The invention relates to the technical means of automatic packaging of viscous materials and can be used for packaging viscous, bulk and liquid products.

The known methods of packaging in viscous products do not provide high accuracy and efficiency of dosing.

The purpose of the invention is the expansion of technological capabilities through the packaging in containers of various sizes.

In a device for packaging viscous materials containing a feeder, a metering device with a drive, a device for automatically feeding tare with a belt conveyor, a tare distributor with a drive and a locking mechanism, a device for automatically feeding tare is provided with a disk unit electrically connected with the drive of the dosing device and with the drive of the container dispenser for feeding the material into the container with the dosing device, the container dispenser being designed as an auger, the metering device In the form of a volumetric piston-type metering device, the locking mechanism contains a contact system electrically connected with the metering and auger drives to stop the metering drive in the absence of container on the auger and start the metering unit when it is fed to the metering position.

The drawing shows a device for packaging viscous materials and appearance.

The device contains a finished product hopper 1 with a screw seal 2, the output of which is connected to a rotating volumetric metering piston 3 of a piston type with a stationary cylinder 4, the connecting nozzles 5 are mounted to the upper and lower openings, inside the rotating cylinder there are two freely

sliding pistons 6 interconnected by a micrometer screw 7, the metering cylinder assembly is rotated by an electric motor 8, on the drive axis of which a dial setting device 9 with a microswitch with a switching contact 10 is mounted, to which a normally closed contact of the second micro switch is connected in parallel with a normally open contact, located in the side portion of the dosing position, and is triggered by the presence of tare 12 for packaging on the conveyor belt 13, where alternately feeding the container for packaging the control by a screw 14 and a distributor roller shock absorber 15, whose work is synchronized with operation of the conveyor driven by the motor 16.

The device works as follows.

From the bunker 1 of the finished product, the material enters the screw compactor 2, which operates in a horizontal position. A volumetric metering apparatus is connected to the outlet of the seal, consisting of a cylinder 3 rotating along the central axis inside a stationary cylinder 4 with upper and lower opposing holes 5. The axis of these holes coincides with the axis of the rotating cylinder. Inside the rotating cylinder there are two freely sliding and interconnected pistons 6. The distance between the pistons is selected by the adjusting screw 7. Packaged material, filling the dispenser cylinder, pushes the pistons down to the bottom dead center to the outlet of the stationary cylinder. From the start signal, the metering motor 8 with the gearbox rotates the rotating cylinder through 180 °. At the same time, the dial gauge on the axis of the rotating cylinder makes a half turn and switches the contact group 10. The rotating cylinder - during the half turn, closes the inlet of the stationary cylinder, and the contents in the cylinder rotates and goes to the empty container 12. , filling the cylinder again, moves the cylinder pistons down. Pistons squeeze the contents in the cylinder compartment into an empty container. Thus, simultaneous filling and emptying of the cavity of the rotating cylinder occurs. The filling volume for given cylinder sizes is determined by the height of the caps and the distance between them. By applying the adjusting microscrew

Between the two pistons, a certain volume of the packaged product is installed.

Empty containers on a conveyor belt 13

screw distributor 14 is alternately fed to the packaging. At each turn of the auger, one container is fed under the filling, and the operation of the auger stops. On a roller shock absorber 15, the container is lifted up to the stop into the sealing gland of the lower opening of the stationary cylinder. After the moment of emptying the auger, having made the next turn, removes the filled container and delivers the next empty container.

When the rotating cylinder stops, the normally closed contact 10 is activated and starts the conveyor engine 16. The motor rotates until the next container is fed to a fixed filling position. At the time of finding the container for packaging, its contact group 11 is triggered, which starts the engine 8 of the rotating cylinder. At the same time, the disk setter breaks the conveyor motor chain and

operation of the auger stops. At each feed of the next container for packaging, the metering engine is started. The dial adjuster, having made a half turn, starts the engine of the conveyor.

In this way, a continuous cycle of container handling and packaging is formed. The packing time of one container is determined by the gear ratio of the gearboxes of two interconnected metering devices and

Tare dispenser; Without the filing of empty containers for packaging, the dosing device does not work.

For bulk and liquid self-flowing materials from the system

the device eliminates the screw compaction, and the finished product hopper is directly connected to the metering device.
