The device consists of the following nodes. | Chain conveyor drive 1 transports empty drums from the warehouse of containers and accumulates them in front of the cutter installed on the roller table 2.

Gate 5 with pneumatic cylinder serves to cut off the flow of calcium chloride coming from the hopper 4 to the dispenser (volumetric) 5 using a vibrator 6 fixed on the hopper .I

The drum feeding unit 7 has a carriage with levers that simultaneously move four drums to a position: "loading," rolling, "weighing and" pushing onto a chain conveyor. Calcium chloride through the boot node

An 8 blade feeder 9 is loaded into a drum mounted on a vibrating table 10 designed to compact calcium chloride in the drum during loading. Lifting table // serves for installation

the drum is on it and the latter is lifted for the purpose of clamping during the rolling of the cover with the help of the node 12 for rolling of the covers. A lid magazine 13 is used to place lidded cassettes in it and provides for gradual (one by one) dispensing of lids. A scale 14 with a recorder serves to weigh the packaged calcium chloride drums. The chain conveyor 15 has hooks that transport the filled drums from the weights to the roller conveyor 16, where they are accumulated and labeled. All the basic mechanisms of the automatic line operate on pneumatics. The automatic line is controlled by electrical limit switches, air distributors and a time relay. The electro-pneumatic control circuit provides a sequence of technological operations. Description of the operation of the automatic bulk filling line The filling machine performs the following operations: supplying empty containers (drums) from the container warehouse for loading, loading the drums with calcium chloride, centering the drums, feeding the lids to the throat of the drums, rolling the lids, weighing the filled drums, dispensing the drums with calcium chloride in the warehouse of finished products. In the empty tare warehouse, the drums are mounted on a chain conveyor drive 1, which transports them from the warehouse and accumulates before loading at the cutter installed on the roller table 2. Pressing the control button switches the gate valve 3. The air is fed into the piston cavity of the slide cylinder. The gate opens and calcium chloride from the hopper 4 enters the dispenser 5. When the gate is opened, the end switch roller is released, for example, type VK-1. The limit switch turns on the vibrator 6, which provides intensive filling of the metering device, as well as the air distributor of the pneumatic cylinder of turning the levers of the device 7 for feeding the drums. Air enters the rod end of the pneumatic cylinder. The levers of the device turn, release the drum and, by pressing the limit switch, switch the air distributor of the carriage air cylinder of the device 7 for feeding the drums. The carriage with the raised levers moves to the left and at the end of the course it pushes an emphasis on the limit switch VK-2. The VK-2 switch switches the air distributor of the pneumatic cylinder of turning the arms of the drum feeding device. The air enters the piston cavity of the pneumatic cylinder, the levers lower and seize the drums located on the roller table 2 with a cut-off valve, under the load and under rolling. When lowering the levers with an emphasis at the beginning of the course, they press the limit switch, which gives a signal to the solenoid electromagnet. The core of the electromagnet is retracted, and through the lever system, the movement is transmitted to the pusher bars. The rods are lowered and free the way for the drum to move. With further lowering of the levers of the device at the end of the turn, an emphasis is pressed on the limit switch. Switch VK-3 switches the air distributor of the pneumatic cylinder of the carriage of the device for supplying drums. The air enters the rod end, and the carriage with the levers holding the three drums moves right and sets an empty drum for loading, the loaded drum is under rolling, and the rolled drum is weighed. When moving the carriage levers hit the limit switch roller, the electromagnet of the roller table 2 with the slam-shut device de-energizes, the slam-shut rods extend and limit the movement of the drums located on the chain conveyor). At the end of the stroke, the carriage of the device for feeding the drums with an emphasis presses on the end switch VK-4, switches the air distributor of the pneumatic cylinder of the loading unit 8. Air enters the rod cavity of the pneumatic cylinder and the device funnel enters the drum throat. When relocating the pneumatic cylinder rod of the loading unit, it stops by pressing the limit switch and switches the air distributor of the pneumatic cylinder of the gate 3. Air enters the rod cavity of the pneumatic cylinder and closes the gate, and also turns off the vibrator 6. the drive of the blade feeder 9 and the vibrator of the vibrating table 10. The product is loaded and compacted in the drum. After a certain time has elapsed, the time relay shuts off the paddle feeder 9 and the vibrating table 10, and also switches the air distributor of the pneumatic cylinder of the loading unit 8. Air enters the piston cavity, and the funnel comes out of the drum neck and presses the end switch of the air cylinder gate 3. Air enters the piston cavity of the pneumatic cylinder and opens the gate. The cycle is repeated. While one of the reels is being loaded, the second, already loaded, is rolled. The loaded drum is fed to the lifting table 11 by a drum feeding unit 7, where the covers are rolled using the node 12. The caps are located in the lid magazine 13. Subsequently, the rolled-up drums are fed to the dial scales 14 by means of the drum-feeding unit 7, where they are weighed and the weighing results are recorded on a belt. After being weighed by the same drum feeding unit, the drums collide on the chain conveyor 15. The chain conveyor hooks the drums and pushes them onto the roller carrier 16, where they are accumulated, labeled and transported to the finished goods warehouse. All trp operations: packing, rolling and weighing are performed in parallel at three positions during the automatic line operation cycle. The work of all links of the line is carried out automatically, and manual control is provided.

Description of the construction and operation of the chain conveyor

The chain conveyor / is intended for transporting calcium chloride drums from an empty container warehouse to a tare installation and provides for the accumulation of baoabans in anticipation of loading.

The conveyor consists of two traction chains 17. envelopes of drive and tension sprockets and moving along guide tracks of the metal structure 18, a drive (conveyor) 19, a frame 20 and a tension screw assembly 21.

The main transmission link is two coupled chains connected by welding with each other with hook brackets 22. to which hooks 24 are attached to fingers 23. The hook is two three-link levers interconnected by two lanes. The upper lobe SERVES to grip the reels, the lower lobe - to limit the turn of the locking element when it is recessed, and the side lobe - to return the zenep to its original position when running onto the unhook 25.
