Carbonated beverage filling lines exhibit considerable variability in terms of product types, bottle shapes, filling methods, and production requirements. Our latest advancements in carbonated drink filling machines and product preparation solutions take this into account, enabling various products to be processed on the same line with minimal size changeover times.

We have taken great care to develop a product preparation range that ensures high standards of finished product quality and the design of fully automatic filling and packaging lines, accommodating the widest array of secondary packaging requirements. This sector experiences significant variability due to ever-evolving trends influenced by end-consumer expectations and habits, and occasionally, changes in regulations.

Multiple Infeed Lanes

The wraping system emerged with multiple infeed lanes to guide bottles into the correct one with smart sensors.
With the high automatic wrapper, you can integrate the wrap process into your Steplead PacTek filling line to shrink-wrapping different kinds of products. 

Control System

Moreover, the infeed tunnels integrated intelligent sensor helps to tell the presence or absence of products. When detecting many products infeeding, by sending signals to upstream to regulate the conveyor speed, it will assure a smooth flowing for the wrapping process.

Working principle of the shrink wrapping machine for beverage production

The bottle and other container which need to be packed is transferred to block bottle plate along bottle separate device. The bottle conveyor will stop when photoelectrical inspector on the top send out a signal, while block bottle plate stand back to release pressed force of bottle. The separate plate up rises to separate packing bottle and bottles to be packed. Push bottle device pushes packing bottle and film along with guild bottle device to sealing & cutting position, meanwhile pushes the last package onto conveyor of thermal shrinkage equipment, meanwhile film feeding device is working. Then the thermal sealing & cutting move downward, to sealing and cutting. The package which been pushed on to thermal conveyor is go ahead and finish thermal shrinking function, finally it goes to storage shelf after cooled by cold wind. The above process fulfills an automatic packing cycle.

The above movements are all done by air cylinder under PLC control, except conveyor system.

Operation flow chart of the shrink wrapping machine for beverage production

Regulation before operation of the shrink wrapping machine for beverage production

  • Check the electrical power to see if it is good, and then switch on.
  • Compressed air source is 0.6MPa
  • The filmfor packaging should put in the right position
  • Adjust the hot sealing temperature to the set temperature, keep it 5mins, set the hot sealing temperature on the temperature controller.
  • The temperature of the machine gets to the set temperature.
  • Check the bottle conveyor, make sure there isn’t any rubbish on the belt.
  • Checkif the right forward direction of conveyor belt and
  • Releasing the emergency stop button.

Operation of the shrink wrapping machine for beverage production

First turn on the machine

  • On the touch screen select “Manual” screen
  • On the touch screen section (4) screen, press “Sealing” button to makepressed film cylinder & sealing and cutting cylinder to stay in right place for about 0.5-1.2 seconds loosened, seal cutter automatically reset.
  • Check whether filmbeen cemented, whether edge is cut off; if not meet the requirements, can be repeated once, while adjusting the stay time, until to meet the requirements.
  • Set to “Auto” position on the touch screen PLC

      1. The operation when changing film also operate again

  1. If the film has been bonded together can omit this operation

Power on for automatic production

  1. Adjust the working time on PLC touch screen, stopped at the “Auto” position
  2. Turn onshrinking machine high temperature conveyor belt and turn on cooling station. Turn on delivery device on the main electrical control box to make it work.
  3. The touch screen display (4) Press the “start” button, the machine enters the automatic production of state
  4. After Poweron should be closely observed if previous procedures to meet the requirements, if not, should immediately stop the process to re-adjust the temperature or time, until satisfied。

Shut down the machine

  • Shouldpress “stop” button in the following cases, the machine should stop work

The machine was breakdown

Bottles overturned on a work plane

  • Aftersealing and cutting operation in the following cases and before the bottle pushing action press “stop” button to stop the machine work

Replace film

Stop production when off working

When heat sealing is not strong because of the need to heat up or the temperature is too high needs cool down

If alarm rang, As a result of the inverted bottle between separated board, bottle can be propped

Note1.when machine stop working the Air cylinder on the position of “O”

Note2. No missing bottles at front of pushing board.

Note3.After replace film , the film should keep tight, but not loose, in case affect the production.  

Note4.After finished production, should also turn off the heating up machine, and working about 20minutes then turn off the conveyor &cooling station, then turn off the power supply.

Set parameter as picture(6):

1.“shrink cut time”: Holding the cutter at the lower end of waiting time 0.5 ~ 1.2S

2.“cool time”: After heat shrink are all completed, then cooling time 0.5 ~ 2.0S

  1. Seclude time: There photodetector material in place, after a delay, seclude bottle time is usually 0.3 ~ 0.8S

4.“Push bottle delay time”: After the completion of seclude bottles, after a delay push package usually 0.2 ~ 0.8S

5.“Push bottle stay time”: Refers to pushed back the package in place then delay for some time and then back into place, usually 0.3 ~ 0.6S.

6.“Reverse time”: Photodetector the bottle in place, the forward stop and reverse open 0.1 ~ 0.3S, easy to push the bottle.

  1. “Lack bottle time”: This parameter is only delivery device head, otherwise no need to set, mainly to prevent the bottle conveyor is insufficient to ensure that each bottle pushing the number of correct

8.“Save parameter”: This button means after parameters are set well, in order to prevent parameter is missing after the machine a long time off working, press this button will call the stored parameters automatically

Note: The first start to use the machine or turn on the machine after a long time stopping, pls check the settings interface parameter settings are normal first, otherwise the device is not operating normally, the specific parameter values can be found in Table (1)

  • Adjust feetof Shrinking machine to make it to a substantially horizontal height, the same foot nut tightened.
  • The Order of the shelves located behind the shrinking machine, adjust the height of conveyor belt same with shelves’level, and finally tighten the nuts of
  • The main control box side has a protruding threading pipe, connect the control lines to right place, closethe rear door, it sits at the side of labeling machine back bottle conveying machine.
  • Turn onthe power and compressed air, on the display screen selected manual position, idling each operation check again, and check if the motor direction of rotation meet the requirements.
  • Finally, select “Auto” positionon display, the empty state press the green “Auto” button, then bottle conveying the work, and then use the opaque plate while blocking four photodetectors (when plate stretch out, the plate was immediately withdrawn), the device automatically enters the work program. Note: can only block the photoelectric switch in the bottle conveying the work, each time a block is one At this time all the equipment installation and testing is completed.

Maintenance of equipment

① equipment must be grounded reliability, it is particularly important to do production in the high humidity environment
