Figure 1 shows a front view of a packaging module with a straight-through thermal knife for automatic packaging of products in shrink film;

figure 2 packaging module in a top view; figure 3-module in a spatial image; figure 4 is a diagram of the storage of film branches between the elements of the nodes of the unwinding of the film.

The packaging module (Fig. 1) contains a frame 2 mounted on height-adjustable supports 1, on which a thermal knife 3 is mounted, a feed conveyor made of sections is connected to the frame 2, located on one straight line passing through the longitudinal axis of the packaging module. The conveyor is a set of interconnected tracks 4, forming, together with other components of the line, a product supply unit included in the former 5 of the product block. A product block is understood to mean several units of products or products, or a plurality of product units combined in a film block.

On the frame 2 of the packaging module, in front of the thermal knife 3 in the direction of the product, a vertically movable table 6 is mounted with the limiters 7 located on it, which are part of the product shaper 5. The packaging module contains a pusher 8 moving in vertical guides for moving products from the upper level of the tracks 4 located on the conveyor frame 9 (Fig. 2) to the level of the receiving table 10 of the module (Fig. 1). The pusher 8 is connected to the rod of the pneumatic cylinder 11, the thermal knife 3 is connected to the rod of the pneumatic cylinder 12, the stops 7 are connected to the rods of the pneumatic cylinder 13. Table 6 is connected to the rod of the pneumatic cylinder 11. The housing of each specified pneumatic cylinder is rigidly fixed to the frame 2 of the packaging module.

In addition to these components, dividers 14 (FIG. 2), cutoffs 15 and brackets 16 (FIG. 2) are mounted on the frame 2, on which the pneumatic cylinders 13 are fixed. The said receiving table 10, which serves for receiving products, is mounted on the frame 2 and movably mounted over it in the guides of the frame 2, a clamp 17 is installed (Fig. 1), connected to a pneumatic cylinder 18 for moving the clamp.

On the frame 2 (Fig. 1), drive rollers 19 connected to the drive are fixed, on which the upper film roll 20 and the lower film roll 21 are supported. Cloths 22 and 23 (Fig. 4) of film rolls forming the upper and lower branches of the film, respectively, are welded together into one web, through which, resting against it, passes a group of products and turns into a film. The film is stored (filled) between the bypass rollers 24 and the tension roller 25, which is movably in the guides 26 of the frame 2.

The thermal knife 3 (Fig. 4) is located above the stop 27 so that when the thermal knife touches the stop, the film branches 22 and 23 located in the rear of the packaging unit from the side of the block motion are pressed by the thermal knife against the stop and welded at 28.

At least one lower roller 19 is connected to the roller drive electric motor 29. The remaining rollers have a rotation drive from rotation of the lower film roll 21, movement of the connected branches 22 and 23 and rotation of the upper film roll 20.

The packaging module is equipped with a film tensioner, which is a U-shaped frame 30 made of a rod, hinged 31 mounted on the frame 2. At one end of the frame 30, a counterweight 32 is movably fixed for fixation, and a jumper is made at the other end of the frame 30 through which it is thrown a film branch 22 running from the upper film roll 20.

On the frame 9 of the conveyor (FIG. 2), a pair of closed circuits 33 is installed, interconnected by tracks 4, forming a plane of product movement along the module, and an electric motor 34 (FIG. 1) connected to the conveyor chains. The electric motor 34 is mounted on the end of the conveyor frame 9 and this end of the frame is connected to the module frame 2 in such a way that it rests on the frame 2.

The packaging line operates as follows. Units of production are fed automatically or manually to the conveyor 4 and when all rows of the conveyor are filled, the sensor for filling the conveyor is triggered, cutters 15 (Fig. 2,3) are moved apart and the products are moved to table 6 (Fig. 1) in the area of the limiters 18. When the table is fully loaded 6 with the product blocks, table filling sensors are triggered, cut-off devices 15 (FIG. 2) are retracted and delayed products on the conveyor 4. At the same time, the movable table 6 is lowered and the pusher 8 is triggered (FIG. 1), promoting the product beyond the plane of the stop 28 (FIG. 4) and termono and 3 to the receiving table 10 (Fig. 2), while the table 6 returns to its original position, the pusher 8 moves back and the clamp 17 (Fig. 1) presses the products to the table 6. Then the thermal knife 3 goes down to the stop 28 (Fig. 4) and there is a welding of the film branches with which the products are wrapped. At the same time, the film is cut off from its web. After that, the thermal knife 3 and clamp 17 rise up by the pneumatic cylinders and the cycle of the line is repeated.

The device presented in the description, due to its layout features, made it possible to create a compact device as a part of a packaging module and a conveyor easily joined with it, and they are connected in such a way that the packaging module and the conveyor essentially represent one compact and simple design. The end of the conveyor frame resting on the packaging module frame significantly reduces the length of the device and increases the compactness of the packaging module. The technical solution was used in the design design of the packaging module UM-1 "Automatic" thermal direct-flow cutter.
