I. Overview

 

 

OR series automatic quantitative packing machines are new generation of self-developed quantitative packaging equipment after our digestion and absorption of foreign advanced technologies. Its salient features are: accurate, low failure rate, wide adaptation and flexible combination.    

 

OR series packing machines are designed by module, discharging with vibration and the weighing hoppers work alternately. You can also choose automatic feeding machines and bag-making machines according to need, so as to further improve packaging efficiency, quantitative accuracy and the degree of automation.

 

automatic powder filling machine  in this series adopts microcomputer control technology, and the weighing units are controlled independently without disturbing each other. It is stable and reliable with high repeatability and low noise. The whole machine is made of high quality stainless steel with high corrosion resistance, and will not contaminate materials. Changes to specifications and materials can be realized through modifying the parameters by the control panel instead of mechanical adjustments. automatic powder filling machine  has such functions as real-time weight display, dynamic measurement weighing, automatic error correction, tolerance alarm, level control, counting, data protection and so on. It is applicable for packing of small and irregular granular materials including: detergent, snack foods, salt, sugar, spices, seeds and so on. Contour of automatic powder filling machine  is shown below:

III. Requirements for Operation

 

     1.The ground should be flat and the environment dry.

 

     2.No strong magnetic field, large airflow and vibration are allowed nearby, or the electronic scale

       will be unstable.

 

3.Power should be well grounded to ensure safety.

 

4.Materials shall not be mixed with foreign matters.

 

IV. Inspection and Adjustment

 

 All parts of the equipment have been adjusted before leaving factory. But fasteners may become loose, causing changes in position in the process of shipping and handling. Therefore, before using automatic powder filling machine  officially, inspection and adjustment should be carried out as follows:

 

     

     Contents of the inspection:

 

      1.Supply voltage is normal or not.

 

 2.The electrical connectors are reliable or not and each fastener is loose or not.

 

      3.Each key is valid or not.  

 

V. Basic Operation

      1.Plug in, turn the power switch on. The  monitor shows AT-FC or full [8] before automatic powder filling machine  goes

       into working state.

 

      2.Press the key [Feed] (i.e. [9] key) on the keyboard. The feeder starts feeding and will stop automatically  

        after reaching material-feeding level.

 

      3.Quantitative calibration. 

 

        1).Manually empty the weighing hopper.

 

        2).Press the key [Zero] to reduce tare weight, so that the weight is displayed as 0.

 

   3).Set weight gap

 

When the material is filled close to the set weight, the difference between the reference value of package weight and the weight upon stopping discharging is the weight gap. When the switch for automatic adjustment of weight gap is "on", the value will be automatically adjusted based on the final weight.

 

Press the key [Set] to display the prompting message [bSZ] for settings of packaging parameters; then press the key [1] to display the prompting message [LC----] for settings of weight gap; input four digits, which stand the weight gap (only the right window double-digit valid); then press [OK] and the buzzer sounds for about 0.5 seconds, which means that the weight gap setting process ends.

 

If you find any mistake, you can always use the key [ESC] to exit, and then restart the operation.

 

    4). Set package weight

 

Press the key [Set] to display the prompting message [bSZ] for settings of packaging parameters; press the key [2] to display the prompting message [ZLJ----] for settings of reference value of package weight; input four digits of reference value of package weight which will be displayed on the right window four-digit and the screen of right window four-digit display prompting message for confirmation [====]; then press [OK] and the buzzer sounds for about 0.5 seconds, which means that the reference value of package weight setting process ends.

 

    5).Set the advanced-slowly-feeding amount

 

Press the key [Set] to display the prompting message [bSZ] for settings of the advanced-slowly-feeding amount; press the key [7] to display the prompting message [tp - - - -] for settings of advanced-slowly-feeding amount; input four digits of advanced-slowly-feeding amount which will be displayed on the low four-digit and the screen of low four-digit display prompting message for confirmation [====]; then press [OK] and the buzzer sounds for about 0.5 seconds, which means that the setting process of advanced-slowly-feeding amount ends.

 

Increasing within a certain range the advanced-slowly-feeding amount can reduce packaging weight error but will affect packaging speed. Too small value of advanced-slowly-feeding amount may result in large package weight error. When filling is completed, the letter "E" shows on the highest position, which means that it is filled to the package weight before automatic powder filling machine  being into the slowly-feeding state. Then, you should increase the advance amount. Operators should, according to their experience, determine an appropriate value of advanced-slowly-feeding amount for every kind of material and discharging screws of different specifications.

 

If you find any mistake in operation, you can always use the key [ESC] to exit, and then restart the operation.

 

6).Set the bag number for automatic feeding (except for the equipment without automatic feeding device)

 

 

Press the key [Set], and the left window shows [gLdS ----]; input the number of automatic feeding bags (no more than 15 recommended) and the number will be displayed on the right window four-digit; then press [OK] (Large number for the package of small size and small number for large size).

 

After the above steps, you can work properly. A quantitative packaging is completed once photoelectric switch is covered. Filling weight may not be accurate at the beginning, but it will be automatically corrected after the buzzer sounds.  

 

 

Note: the value of weight gap generated by ration which may result in inaccurate quantity. This problem may be solved by automatic correction by electronic scales for several times. You can also adjust manually with the following method:

Press the key [Set] and then press [5]. The current value of weight gap will be displayed, and take this value as a reference; input a new gap value, then press [OK].

 

The value of weight gap will not lose due to power failure. The value in use is automatically adjusted,  so it may not be the original figure you have set when automatic powder filling machine  starts up next time. 

VI. Query of Parameters

 

This operation is mainly used to view or record the current parameters. When package specification or feeding materials are changed, you can directly input the corresponding values without having to repeat the calibration process. The parameters can be queried include: reference value of weight, upper limit value of weight, lower limit value of weight, coarse addition value, weight gap value, automatic adjustment switch, number of automatic feeding bags, coarse addition amplitude and fine addition amplitude. Press [Set] and corresponding number key for query and press [ESC] to end the query. See Appendix I. Reference List for Common Operation

 

VII. Settings of Count Switch

 

When the count switch is On, counting function works and when the count switch is OFF, counting function does not work.

 

Press the key [Count] and the monitor displays [JSCL]; then press [4], and the monitor shows [JS   -]; then input the value for states of switch ( [1] for On and [0] for OFF). Once you have done this, the low four-digit will display [==== ], then press [OK] and the buzzer sounds, which means that the settings of count switch process ends.

 

The setting of count switch state is not retained. After power-up or reset, its default state is OFF.

 

 

VIII. Emptying

 

This function is applied when the materials in the hopper are required to be emptied; press the key [Clear] (i.e. [0]) to empty the weighing hopper. It is suggested to empty the materials within the hopper every time for shutdown.

 

IX. Manually Feeding

 

Manually feeding is used only for maintenance or feeding for the first time. Press the key [Feed] to start feeding and then press the key [Feed] again to stop feeding. (It is used with automatic feeding device.)

 

X. Zeroing

 

Weight display should be zero after automatic powder filling machine  is powered on. If the electronic scale display is not zero or there are materials in the hopper, you should clear the hopper and press [Zero] for display of zero or you should carry out the operation of empty materials 

 

XI. Common Failures and Treatment

 

Phenomenon 1: No display after turning it on.

 

Check if the power supply is properly connected, and the ground wire is used as the null line as well as the protector tube is invalid.

 

Phenomenon 2: [CHAO] displays on the monitor  

 

Cause: The electronic scale is currently in the state of overloading. The electronic scale may not be properly calibrated or may be also damaged by large stress.

 

Solution: 1) re-calibrate the electronic scale, 2) replace the sensor.

 

If the electronic scale is in the overload state, any operation should be terminated.

 

Phenomenon 3: [E3] displays on the monitor

 

Cause: It indicates that no weight is put on it when the electronic scale is calibrated.

 

Solution: Use [ESC] key to end and re-calibrate it.

 

Phenomenon 4: The photoelectric switch reacts insensitively.

 

Cause: It may be caused by too much dust on the inductive head of photoelectric switch or too low sensitivity.

 

Solution: Wipe off the dust on the photoelectric switch or improve the sensitivity. When wipe it, please enter the state of [bSZ].

 

Phenomenon 5: Covering the photoelectricity but it doesn't discharge.

 

Check: 1) Is the red indicator always on? If it is always on, the sensitivity screw can be rotated anticlockwise. 2) When covering the photoelectric switch, is its red light on? If it isn't on, check if the voltage of photoelectric switch is normal (should be 12V); and check if the signal line voltage of photoelectric switch is normal (about 0V when it is covered, and 11V when not covered), and replace it if it isn't normal.

 

    

    Phenomenon 6: Inaccurate discharging

 

Cause: Too wet or caking materials, and wrong operation methods.

 

In addition, too large change of the level of material inside the hopper, or instable grid voltage can also cause the result.

 

Phenomenon 7: Irregular vibration of the vibrator

 

Cause: May be the instable power supply voltage or clutter of the power supply.

 

It is recommended that provide constant voltage power supply and do not share the same circuit of power supply with the large equipment.

 

Phenomenon 8: Inaccurate weighing

 

   Cause: May be that the looseness of the adjusting pin of the vibrator causes the touch of oscillator and weighing hopper (re-lock it), or the sensor is damaged (replace the sensor).

 

   

   Phenomenon 9: Material leakage of weighing hopper  

 

  

   Cause: May be that the door opening turn cut nut is loose, door opening spring breaks off, or door opening time is set too small. Also it may be the deviation of position of door opening tumbler (turn the power off, put the tumbler turn to the bottom).

 

Phenomenon 10: Zero of the electronic scale is instable.

 

  

   Cause: May be that the mounting bolts of weighing hopper are loose, or the large humidity of working environment causes the control circuit board damp. An electric drier can be used to drive the moisture away. The temperature should be controlled at 40 ~ 50 ℃ for about 10 minutes.

 

Phenomenon 11: The feeder doesn’t feed.

 

Cause: The material level switch sensitivity is too high or the ends are bonded with materials.

 

Solution: Reduce the sensitivity (the same way as photoelectric switch), remove the material level switch and clean the materials.

 

XII. Maintenance

 

The following matters should be paid attention during the operation of the equipment:

 

1. Power supply voltage should be 220V ± 10% and the power frequency should be 50Hz ± 2%. As well as it should be grounded well.

 

2. Electronic scale cannot be impacted by overload and prohibit the large stress on the platform.

 

3. Electronic scale should be running in the no vibration and dry environment.

 

4. The feeder should not be mixed with debris.

 

5. Please clean automatic powder filling machine  when it is free, and place it under dry and ventilated space.

 

6. If there is any abnormal noise when automatic powder filling machine  is working, cut off the power immediately.

 

Appendix I. Method to Change the Original Parameters

 

Original parameters to be changed include: filtering times, calibration segments, tare weight of removing weighing hopper, calibration of electronic scales, division, discharge delay and so on. These parameters have already been set in the factory. Please read the following carefully when weighing reads inaccurately or needs to be reset after replacement of major components:

 

If the following operations are not carried out before start-up of the packaging machine, the monitor may keep flashing or read data incorrectly, then you can do the following operations in sequence:

 

Enter Set State:

 

Press the key [Reset], next the key [Set] for about 3s, the left window displays[CSZ], meaning the set state has been entered; Firstly, enter the password (9999), re-enter the password if incorrectly or exit by using the key [ESC] (password failure), and only after entering the correct password then the following operations can be performed. If there is any mis-operation during the process, you can always press the key [ESC] to back to the [CSZ]state, and start to re-operate.

 

1. Set Filtering Times

 

Filtering times: namely, the mathematical processing for the data of electronic weighing scales.

 

Under [CSZ] state, press the numeric key [1] to display [CS --] entering the state to set the filtering times;  enter two figures which will be displayed on the right window double-digit of the monitor, once you have done this, the right window four-digit will display [==== ], then press [OK] and the buzzer sound, which means that the filtering times setting process ends. The figures entered range from 3 to 10. For example: if the filtering times are 5, then you shall enter “05”. It is recommended 10 as the filtering times to be set.

 

Under [CSZ] state, press [ESC] to return to working state.

 

Filtering times will not be lost due to power failure.

 

    2. Set Calibration Segments

 

Calibration segments: namely, the number of segments divided when calibrating the electronic scale.

 

Under [CSZ] state, press the numeric key [2] to display [dS --] entering the state to set calibration segments; enter two figures which will be displayed on the low double-digit of the display, once you have done this, the low four-digit will display [==== ], then press [OK] and the buzzer sounds, which means that the calibration segments setting process ends. The figures entered range from 1 to 5. For example: if the calibration segments are 3, then you shall enter “03”. The calibration segment usually is 1.

 

Under [CSZ] state, press [ESC] to return to working state.

 

 The calibration segments will not be lost due to power failure.

 

3. Confirmation of Endodermis Value

 

Endodermis Value: namely, the electronic scale's original zero value. At this point the electronic scale displays steadily without flashing.

 

Under [CSZ] state, press the numeric key [3] to display [NP ====], then press [OK] and the buzzer sounds, which means that the confirmation of endodermis value setting process ends.

 

Under [CSZ] state, press [ESC] to return to working state.

 

The endodermis value will not be lost due to power failure.

 

4. Calibration of Electronic Scales

 

Calibration: namely, calibrating electronic scales and only calibrated electronic scales can be used. It must be calibrated after replacing the sensor and the main board.

 

Set the number of segments (1~3, unusually 1) prior to calibrate.

 

The weight used for calibration should be the Level 3 verified standard weight.

 

Before calibrate the first segment, the platform shall be remained empty. Don't remove the calibration weights of the previous segment when calibrate the subsequent segments.

 

Under [CSZ] state, press the numeric key [4] to display [dS --], then enter the calibrated segments serial number which will be displayed on the low double-digit of the monitor, after a while the monitor displays [Cbd ---- ], which means that the calibration status has been entered; Enter the four-digit weight value of the weight (in units of g), which will be displayed on the low four-digit of the monitor. Enter zero if the weight value is less than four digits. For example: if the weight used weighs 100g, then you should enter 0100. After entering the weight value, the low four-digit will display  [==== ], then put weight on the scale, press [OK] when the scale resumes stale(about 5s) and the buzzer sound for about 0.5 seconds, which means that the calibration of this segment ends.

 

Calibrate the other segments like this.

 

Under [CSZ] state, press [ESC] to return to working state.

 

The calibration segments will not be lost due to power failure.

 

5. Set Division.

 

Division: namely the minimum resolution when the electronic scales read the weight value.

 

Under [CSZ] state, press the numeric key [5] to display [Fd --], then enter the number between key [3] to [6], 3 means the division is 0.5, 4 means 1, 5 means 2 and 6 means 5. The number entered will be displayed on the right window of the monitor. Once you have done this, the low four-digit will display [==== ], then press [OK] and the buzzer sounds, which means that the division settings process ends.

 

Under [CSZ] state, press [ESC] to return to working state.

 

The division will not be lost due to power failure. Just once operation is need for the same kind of packaging specifications.

Appendix III. Operation for Optional Devices

 

The feeding device has the function of automatic feeding. The start and stop of feeding device are controlled by the material-feeding and material-discharging level. The material-discharging level is determined by the number of bags, and the material-feeding level is determined by the material level controller. That is to say, after a certain number of bags being packed, the feeding device feed and the material level controller stops feeding after receiving the signal. Set the number of bags for automatic feeding before operation. Please see the preceding section VI 5 on page 6.

 

The installation and adjustment process of material level controller are as following:

 

Connect the power: open the electrical box door on the lower part of the packaging machine, connect the wiring of the feeder through the reserved holes to AC contactor terminals.

 

 

Switch on "Total Power", press the key [Feed] (i.e., the key [9]) orderly to observe the feeder direction of rotation. If the direction is wrong, exchange the wiring.

 

Adjust sensitivity: rotate the sensitivity knob while putting your hand near the end and keep the distance for test about 100 mm (Our company has adjusted before the product leaving factory).

 

Install the material level device on the viewing window board. Cover the board and press it with press strips.

 

 

Notice:

 

1.No debris shall be contained in the materials.

 

2.The fasteners are loose or not.

 

3.Add lubricant to upper rotating parts once every month.

 

4.Operators should not wear a skirt, gown and so on when working. Please pay attention to safety when the  

       motor is working. Cut off the power when troubleshooting automatic powder filling machine .
