    4.How To Operate A Doypack Filling & Screw Capping Machine?

    A doypack filling & screw capping machine can be operated by following few easy steps which are enlisted below:

    Operate A Doypack Filling

    Machine Loading

    Machine Loading

    Doypack loading into machine- Picture Courtesy:

    The very first step required for operating the machine is loading it with material. In case of doypack filling & screw capping machine, it must be fed with premade empty doypacks, sufficient volume of liquid to be filled in pouches, and stock of caps to be placed over filled doypacks. Now, it is significant to know that each mentioned material has its fixed place in the machine, and you need to load these objects in relevant components.

    Machine Setting

    Machine Setting

    Machine setting- Picture Courtesy:

    Once the loading phase gets done, the setting of machine will be carried out in next step. Here, the operator will adjust basic parameters of the machine including the volume of liquid for each doypack, speed of filling, temperature of material hopper, and the pressure of torque for cap screwing etc.

    Doypack Conveying

    Doypack Conveying

    Doypack conveying- Picture Courtesy:

    During this phase, the machine will be turned on by operator after which it will begin functioning. As the machine is powered on, it will start conveying empty doypacks from rack towards main machine. This is carried out when the spouts of pouches are gripped in the collar of gripping unit and doypacks are mobilized forward.

    Doypack Filling

    Doypack Filling-1

    Doypack filling- Picture Courtesy:

    Once doypacks reach to the filling station, the diving nozzles sit on the spout to ensure enclosed filling for proper pouch expansion. Similarly, the material coming from hopper through the weighing system is gently dispensed into doypacks. During this time, the machine control system makes sure to maintain precise filling while reducing waste and fill level inconsistencies.

    Doypack Capping

    Doypack Capping

    Doypack capping- Picture Courtesy:

    Proceeding further, the filled doypacks are moved ahead for capping where a vibratory or rotary sorter convey the caps to chute. This chute, when contacting the passing filled doypacks, keep releasing the caps over doypacks. In this way, caps are placed over pouches and then by using a rotating capping head, caps are tightly screwed.

    Doypack Discharging

    Doypack Discharging

    Finished doypacks discharging- Picture Courtesy:

    Once the doypacks are capped, they are discharged from machine through a chute and transported through a conveyor for further packaging or collection into a container. At this point, the defective doypacks are rejected from the properly packed ones to reduce production line stoppage.

    5.Describe The Components Of A Doypack Filling & Screw Capping Machine?

    Doypack filling & screw capping machine is composed of several parts each performing its own task. However, these components may vary from one type of machine to another with more or less having same functions. In this question, you will know about the various parts of a fully automatic doypack filling & screw capping machine:

    Components Of A Doypack Filling & Screw Capping Machine

    Components of SF RANGE FOOD- SPOUT FILLING/CAPPING MACHINE- Picture Courtesy:

    Material Hopper

    Material hopper is one of the essential components of a doypack filling & screw capping machine which comes in large size to hold large volume of liquids for processing. Inside hopper is the fitted system of heat which keeps the material at suitable temperature level to avoid jamming.

    Piston Filler

    Piston filler is another core part of the machine that is attached to the hopper of machine. It is a weighing device that measure the exact volume of liquid by using piston. Therefore, the material is first transfered from hopper into piston filler and then transported from here for filling into doypack through nozzles.

    Cap Feeder

    The machine has another feeding unit which is known as cap feeder. Here, bulk of caps are loaded before initiating the process and caps are supplied to machine through this unit.

    Electronic Control Panel

    This tool is considered the brain of the machine as it is the sole part through which machine can be regulated and its functioning can be controlled. It mainly consists of a PLC touch screen which display over it multiple information regarding machine like filling volume, sealing temperature, and torque pressure for capping. Along with that, this part has certain knobs like emergency stop, power switch and indicators etc.

    Feeding Rack System

    Feeding rack system is a tool attached to the main machine. Its function is to supply the machine with prearranged empty doypacks.

    Stainless Steel Body

    The body of machine is made up of GMP'S regulated stainless steel with all parts contacting material are fully corrosion resistant and antibacterial. The overall structure of machine is highly stable with several feet which enable machine to stand stable on surface.

    Doypack Gripper

    As the name demonstrate, doypack gripper is a device which takes the doypack from feeder towards filling station by perfectly gripping their spouts in its clamps. Therefore, it removes the fear of doypacks getting deviated from path.

    Transparent Window

    The machine has a transparent protected window which enables you to observe the operation while as protecting the inside operation from external environment that may pollute it.

    Filling Station

    It refers to the station where doypacks are filled with liquids. This filling station has multiple filling nozzles through which liquid is dispensed into doypacks.

    Capping Unit

    Capping unit is located right after the filling station. It includes the cap placing device, screw device, and a torque. It basically carries out the function of placing caps over doypacks and screwing them tightly.

    Discharge Chute

    Discharge chute is the last section of machine through which finished doypacks are ejected out of machine for further packaging.
