The invention relates to devices for packing small-piece products, preferably in packages of heat-sealing material, and can be used in the food industry.

The aim of the invention is to increase productivity.

Figure 1 shows schematically the proposed device, a general view of figure 2 is a device control circuit; FIG. 3 shows the device before the start of the operation. FIG. 4 is the same at the moment of formation of the bottom; FIG. 3 is the same when the bag is loaded with a coarse weight dozing; Fig. 6 shows the same at the moment of cutting off the product flow; in Fig. 7 it is the same when the weight dosing chamber is released; 8 - the same, when the product is compacted, the neck is formed and the fluid is supplied; Figure 9 is the same when printing a package; figure 10 is the same, at the time of removal of the packaged package.

The device comprises a hopper 1, roll holders 2 with unwinding mechanisms 3, mechanisms 4 forming a longitudinal seam of the bag 3 on the mandrel 6 of the bunker 1, mechanisms 7 sealing the bottom and neck of the bag 3, air supply systems, containing a drive 8 controlling the air reducer 9 , pipelines 10 and .11 spool valves 12 and 13 with actuators 14 and 15 controlled by a contactor

16, the weighing dosing sensor 17, two pairs of hollow elastic dampers 18 and 19, which are successively located at the outlet of the hopper 1, form between the weighing dosing chamber and connected to the air supply lines 10 and 11 in their cavities.

Weight dosing sensor 17. associated with actuators 8, 14 and 15 of the air supply system. The bunker 1 and the mechanisms 4 for forming a longitudinal seam are fixed on the frame 20 mounted on the platform 21 and connected with the mechanism

22 step motion. A hydraulic weight metering device 23 comprising a pallet 24 for installing navivnyh drums

23 and the chamber 26 is connected to the weight dosing sensor 17.

In the lower part of the mandrel 6, under the flap 19, there is a collector 27 for supplying fluid to the bag 5, and on the frame 28 at one of the positions a sealing mechanism 7 is installed; The bottom and the neck of the bag 3 containing the knife 29. On the movable parts of the mechanism 7, a pneumatic device 20 30 is installed to seal the air and form the neck of the bag 3, consisting of semi-annular inflatable chambers communicated with the air supply system.

The device works as follows.

The coiled drum 25 is placed on the pallet 24 at the loading position.

(.fig. 1). At the same time, the gearbox 9 supplies the medium, for example air, under the highest pressure through pipelines 10 and 11 to the valves 18 and 19 (Fig. 3), which, filling with air, block the outlet of the bunker mandrel 6 and hold the fish. In this position, the longitudinal seam mechanisms 4 glue the heat-adhesive film together to form a sleeve and push it down into the drum.

When the platform 21 with the hopper 1 is rotated to the second position (FIG. 4), a mechanism 7 for sealing the bottom and neck of the bag is brought to the sleeve, which compresses the sleeve and imposes a metal compression ring on it, and cuts the edge of the sleeve under the package bottom with a knife 29. In the third position (FIGS. 2 and 5), the contactor 16 includes actuators 14 and 15, which switch the spools 12 and 13 together in the cavity

pulsating air supply is then to the valve 18, then to the valve 19, which contributes to the destruction of the arch and the prevention of the laying of the fish, rocking, destroying the lower layer of the fish.

The average air pressure provided by the gearbox 9 does not allow the dampers to completely block the outlet 10 of the mandrel 6. The bag 5 in the winding drum 25 is filled more slowly but uninterruptedly, and the pointer of the manometric sensor 17 moves to the second position,

15 wherein the sensor 17 transfers the reducer 9 to the supply of maximum pressure during its pulsating flow to the flaps 18 and 19. The opening of the mandrel 6 is blocked completely but alternately

20 either by valve 18, then by valve 19. Since an intermediate tank a is formed between them, when the valve 19 is open, the valve 18 is closed, the tank a is filled

dampers 18 and 19 with atmosphere, pressure - 25 (Fig. 6), and when damper 19 is closed,

the valve 18 is open, the container a is released from the fish, feeding its portion into the bag (Fig. 7). Then the valve 19 is closed. The valve 18 is closed, the tank and cut off from the mass of fish in the mandrel 6 (| Fig.8).

In this way, a slow serving of fish into the bag takes place.

When a fish hits between the dampers, it is not injured, and the pressure pulsation in the damper 19 (Fig. 2) constantly shakes the lower layers of the fish in the mandrel, preventing its formation and bedding.

When the standard weight reaches the package, the pointer of the sensor 17 goes to the mark M, turns off the drive of the reciprocating movements of the spools 12 and 13 and the pressure pulsation of the lazy stops the dampers closed, the pressure of the reducer is maximum.

In the fourth position of the scapular movement, the mechanism 7 for sealing the bottom and the neck of the package 5 (Figures 1 and 8) and the pneumatic device 30 are brought to the winding drum 25. Air is supplied to the device chambers, they increase in volume, press the product down, remove it from the package 5 . Air and crimping the neck of the package 5. Simultaneously, the helix is fed to the collector 27, which, when the bag is packed, fills it, and the mechanism 7 compresses the sleeve and applies

the drop in them falls and the opening of the mandrel 6 opens completely. The fish begins to fill the sleeve, moving the mandrel 4 with the mechanism 4 until the navivaya drum 25 is filled with the product, and the actuators 14 and 15 immediately switch the spools 12 and 13 to their previous position, connecting the cavities of the flaps 18 and 19 to the pressure reducer 9 of the highest pressure, the flaps 18 and 19 fill the opening of the drum 6 and re-open both at the same time. The naval drum 25 acts on the hydraulic device 23 of the weight dosing (Fig. 2). As the number of fish in the package increases, the pointer of the manometric sensor 17 moves to the first position, providing during this time a coarse batch dosing mode, but not allowing a speed overflow of the bag.

In the first position, sensor 17 switches actuators 14 and 15 to alternate pressure supply to dampers 18 and 19, gear 9 to medium pressure to create dampers 18 and 19 at the exit of mandrel 6, a slit for fine-jet feeding of fish into the drum.

Since the reduction in size and the flow area for feeding fish increases the risk of arching, alternating

pulsating air supply is then to the valve 18, then to the valve 19, which contributes to the destruction of the arch and the prevention of the laying of the fish, rocking, destroying the lower layer of the fish.

The average air pressure provided by the gearbox 9 does not allow the dampers to completely block the outlet port of the mandrel 6. The bag 5 in the winding drum 25 is filled more slowly but uninterruptedly, and the pointer of the manometric sensor 17 moves to the second position,

5 whereby the sensor 17 converts the reducer 9 to the supply of maximum pressure during its pulsating flow to the flaps 18 and 19. The opening of the mandrel 6 is completely blocked, but alternately

0 then the flap 18, then the flap 19. Since an intermediate tank a is formed between them, then in the case when the flap 19 is open, the flap 18 is closed, the tank a is filled
