The feeding mechanism 2 (Figs. 1, 2, and 3) of the film sleeve includes a bobbin holder 8, a sleeve roll, a vertical frame 9 carrying preparatory rollers 10. It is fixed on an axis with a roller 11. A supporting roller device 12 having two pairs of vertical rollers 13 and two pairs of horizontal roles 14.

A device 3 (Fig. 3) for opening the film sleeve and shaping the desired profile is placed inside the supporting roller device 12 and contains two pairs of vertical rollers 16 mounted on the frame 15, working together with the rollers 13, and a pair of horizontal rollers 17 working with the rollers 14. The vertical rollers 16 and 13 are placed in pairs at the corners of the frame 15. At the end of the latter, parallel horizontal guides 18 are fixed along the process, forming a rectangular space between them to form a film from the sleeve rectangular volume.

Each bending guide 18 (Fig. 3) is spring loaded relative to the frame 15 and consists of two L-shaped parts interconnected by a spring 19.

In order to eliminate the film slack during the formation of the film sleeve and during welding, its device 3 is equipped with an additional compensator 20 and an expander 21.

The compensator 20 (Fig. 3) is made of a spring wire, mounted above the frame 15. The latter forms a spring cavity with the frame 15.

The expander 21 (Fig. 3 and 4) is made in the form of drive scissors, the working part 22

which is placed between the flexible guides 18 and has an elongated curved shape. The scissors drive 23 is made in the form of rollers 24 at the ends of the inoperative part interacting with the rollers 25 (Fig. 7) mounted on the supporting roller device 12 and receiving movement from the mechanism 5 for welding and cutting the film sleeve.

The mechanism 4 for pulling and putting the sleeve from the film onto the frozen fish block (Figs. 1, 4, 5) includes a carriage 26. Moving along the roller bearings 27 and carrying the gripping jaws 28. Between the gripping jaws 28 there is a groove 29 mounted on a platform formed the rough flexible tapes 3 (3, the carriage 26 is driven back and forth by means of an individual drive 31 (FIG. 4) operating reversely.

Two pairs of gripping jaws 28 are mounted on the carriage 26 with the possibility of additional movement relative to the latter at the extreme points of its location: at the beginning of the packaging process when the jaws 28 grasp the vertical edges of the film sleeve and at the end when they are removed from the packaging zone. To this end, each pair of gripping jaws 28 is mounted on a gear rail 33 including a rail 32 kinematically connected to the rail 33:

A lever 34 is mounted on the walls of the carriage 26. When turning it, by means of the cam 35 mounted on it, the jaws 28 are closed or disconnected. Each toothed rack 32 receives a drive from peers of fixed stops 36 fixed to frame 1 at the beginning of the packaging process, and from a pair of movable stops 37 (Fig. 4) at the end of the packaging process. At the beginning of the packaging process, the lever 34, in cooperation with the stop 38, closes the jaws 28 by means of a cam 35 located on it, and at the end of the packing process, the stop 38 opens the jaws. On the levers 34, in addition, hooks 39 are secured, which fix the groove 29 for its two ledges 40 while jointly moving the carriage 26 with the groove 29 towards the device 3 for opening the film sleeve. The ledges 40 are located on the outer lateral sides of the trough 29. On the upper crossbar of the carriage 26 there is (strengthened) a tilted visor 41 to protect the sleeve of the film from above when packing a block of fish and in the center of the crossbar there is a copier 42.

The rectangular chute 29 is mounted on a pair of flexible tapes 30. The latter are flat belts with a corrugated surface that envelope two pairs of stationary rollers 43. The tapes 30 are moved in a rigid IJ-shaped deck 44, the height of which does not exceed the height section of the belts 30. The ends of the belts 30 are fixed on two opposite sides on the frame of the carriage 26. A rough platform of flexible tapes 30 facilitates pulling the sleeve of the film when putting it on the chute 29 with a block of frozen fish.

To reduce the overall dimensions of the device, it is equipped with a cassette 45 (Fig. 4.6) for receiving the gutter 29, The bottom 46 and the wall 47 of the gutter 29 are interconnected by an amount not exceeding 1/3 of the length of the gutter 29. The specified cassette 45 is mounted on the frame 1 in the end of the device during the packing process and is made in the form of horseshoe-shaped vertical guides that form two channels 48 of variable cross-section for receiving the walls 47 of the groove 29 when removing it from the film bag and two symmetrical guides 49 designed to receive the bottom 46 of the groove 29. For fixation walls 48 in the channels 47 terminate last vertical rollers 50;

The movement of part of the groove 29 into the cassette 45 is carried out by a chain 51 fixed to the end of its bottom 46, from the side of the cassette 45. In this case, the chain 51 is passed through a series of sprockets that kinematically couple the chute 29 to a common drive 52 of the device.

The drive 52 (Fig. 4) includes a drive 53 and a camshaft 54 mounted perpendicularly and interconnected by bevel gears 55. The camshaft 54 is located along the device. A series of cams 56. 57, 58 and 59 are fixed on it according to a certain sequence diagram, by means of which the mechanisms and devices of the inventive device are sequentially activated in the program recorded on the cams. Thus, the aforementioned chain 51 is driven by a cam 59 when pulling the chute 29 from the bag and fixing it in the cassette 45. At the bottom 46 of the chute 29 (Fig. 6), in the fastening zone of the chain 51, a fixed stop 60 is installed to prevent movement troughs 29 with a block of fish together with the carriage 26 at the place of putting on the opened sleeve of the film by mechanism 4.

The mechanism 5 for welding and cutting the sleeve of the film (Fig. 4, 7) contains the upper welding jaw 61 and the lower 62. Together with the upper jaw 61, a sawtooth knife 63 is mounted, and from the bottom 62 there are paired sawtooth plates 64, cutting together with the knife 63 film after welding. The welding jaws 61 and 62 are moved from a common drive 52 through a chain gear 65 and an intermediate shaft 66. Two cams 67 and 68 are fixed to the latter. The cam 67 is kinematically connected to the rollers 25 of the device 12, which act on the rollers 24 of the expander 21 when the film is expanded , and the cam 68 provides the closure of the welding jaws 61 and 62.

The device 6 (Fig. 1, 4, 5), designed to feed frozen fish blocks into the chute 29 and remove the packed blocks from the device, contains a conveyor 69, a lifting platform 70, a pusher 71 and a feeder 72. The lifting platform 70 is equipped with a presence sensor 73 on it, the block is driven by the cam 57 of the camshaft 54 from the common drive 52 via a linkage system. The pusher 71 (Fig. 2), which feeds the blocks to the feeder 72, is kinematically connected to the cam 56 of the shaft 54.

The feeder 72 (Figs. 1, 4, 5) consists of two symmetrical corners 74 mounted on the frame with the possibility of rotation by 90 ° and interconnected by a system of levers 75 closed to the cam 58 of the shaft 54.

The feeder 72 is equipped with two electrical sensors (not shown), one of which detects the presence of a fish block in it, and the other automatically turns on the drive 31 of the carriage 26. In addition, it is equipped with a movable lever 76 in contact with the abutment 60 of the groove 29 while being put on it sleeves of a film. The lever 76 is kinematically coupled to the cam 59 of the camshaft 54. The cam 59 makes contact of the stops 76 and 60 while removing the chute 29 from the film bag. In addition, the cam 59 is kinematically coupled to the movable stop 37 acting on the lower gear rack 32, which allows the gripping jaws 28 to move relative to the carriage 26 in the final packaging step of the frozen fish block.

The removal of a pack of frozen fish packaged in a sleeve film welded on one side is carried out simultaneously with the process of loading a new block of fish using the pusher 71 into the feeder 72.

The device operates as follows.

Before starting the operation of the device, the film sleeve is partially wound from the bobbin holder 8 and refilled through the rollers 10 and 11, after which it opens

the cover 77 of the supporting roller device 12, the sleeve is passed into the inside of the latter, and the device 3 is manually installed inside the sleeve to open the sleeve and form a volume from it

0 desired shape. After that, the device is fixed in the support device 12 by means of vertical rollers 16 and 13 and horizontal rollers 17 and 14, clamping the film inside and out. The roles are 5 ki 25 plant tf also inside the sleeve of the film. After that, the lid 77 is lowered. The device is ready for use.

After that, the block of frozen fish with its elongated face is conveyed by conveyor 69 to the lifting platform 70 and the sensor 73 installed on it activates the general drive 52 of the device. From a common drive 52 through an intermediate 53 and a camshaft 54, on

5 of which a cam 57 is mounted, and a lever system linking pad 70 with a cam 57, the system fires and raises the pad 70 with the fish block to the level of the base of the loading niche of the feeder 72. Then

0, the pusher 71, driven by the cam 56 of the camshaft 54, moves the block into the niche of the feeder 72, after which the pusher 71 returns to its original position and acts on the sensor located next to it, which drives the drive 31 of the carriage 26.

When the carriage 26 moves in the direction of the tool 3, the hooks 39 are fastened behind the levers 34 of the gripping jaws

0 28, hook the chute 29 into two steps 40 and pull it along. In this case, the gear racks 32 abut against the fixed stops 36 and get the movement in the opposite direction, while the gripping jaws 28 located on the racks 33 are moved forward.

When the rotary levers 34 are locked with the fixed stops 38, the jaws 28 with the cam 35 are closed, capturing the open ru

0 cav film on both sides. In this case, the groove 29 is fixed under the feeder 72 with the help of the movable lever 76 of the feeder and the stationary stop 60 of the groove 29, mounted on its bottom 46.

5 At this point, the cam 58 of the camshaft 54 acts on the linkage system 75 by turning the corners 74 of the feeder 72 90 °. The fish block is shifted to the gutter 29. When the corners 74 return to their original position, they act on

a feeder sensor that includes a drive 31 of the carriage 26; making a reciprocating movement on the roller bearings 27 (Fig. 1, 4, 5) due to the reversibility of the drive 31.

The lever 76 holds the gutter 29 with the fish block, abutting against the support 60, when the carriage 26 starts reversing in the opposite direction with the film sleeve fixed by the jaws 28. The previously opened film sleeve has to be put on the stationary gutter 29, in which there is block of fish or other item.

When the carriage 26 moves in the opposite direction, the bar is wound from the bobbin holder, passes through the rollers 10 of the frame 9, the tool 3 and the guides 18.

When the carriage 26 moves in the opposite direction along the stationary trough 29, the film is put on the trough. Flexible tapes 30 moving together by carriage 26 provide tensioning of the film sleeve to the groove 29.

When the carriage 26 reaches the extreme position, the gripping jaws 28 are opened due to the interaction of the pivot arm 34 with the fixed stop 38 of the frame 1. The open jaws 28 continue to move after the carriage 28 stops due to the contact of the gear rack 32 with the movable stop 37 by acting on the last cam 59 of the camshaft 54. Moreover, the cam 59 simultaneously acts on the movable lever 76 of the feeder 72 and, by means of the copier 42, disconnects its contact with the stop 60, thereby securing the block of frozen fish lever Agom 76.

At the same time, the cam 58 (Fig. 4. 5) of the common drive 52 acts on the sprockets 78 of the gear 79, including the drive of the chain 51, removing the groove 29 from the package. Since the bottom 46 and the walls 47 are not interconnected, they are fixed in the channels 48 And guides 49 of the cassette 45. Thereby, the overall dimensions of the device are reduced. Thus, the trough 29 is pulled out of the sleeve and the fish block remains in it, held by the lever 76. After removing the trough 29 from the sleeve film, the lever 76 is also removed from the package by means of the lever system 80.

When the gutter 29 is removed, a mechanism 5 is activated to weld and cut the sleeve. The drive of the mechanism 5 is carried out from the general drive 52 of the device through a chain transmission 65 and an intermediate shaft 66, carrying the cams 67 and 68. Thus, the cam 67 is connected through levers to the rollers 25, compressing the rollers 24 of the expander

21, the working parts of which stretch the film sleeve. A cam 68 of the shaft 66 closes the welding jaws 61 and 62 gluing the film, and a sawtooth knife 63 and identical plates 64 cut off the film sleeve on one side with a packaged fish block. When welding jaws 61 and 62, knives 63 and 64 return to their original position, flexible guides 18 extend the film sleeve.

 The film-wrapped fish block, brewed on one side, is removed from the device by means of a pusher 71 moving the new block to the feeder 72. After this, the cycle is repeated.

A device for packaging items, e.g. blocks of frozen fish, in a tubular film has several advantages over known ones.

firstly, injury or rupture of the edges of the film is avoided by reducing the efforts of the gripping jaws 28, which is associated with the introduction of rough flexible tapes 30, dragging the film from the bottom when putting it on the gutter. At the same time, two elements were introduced into the device: a compensator 20 and an expander 21, which prevent the formation of corrugations, adversely affecting the packaging quality and the quality of the weld ..

Secondly, in order to reduce the overall dimensions of the device, which is especially important in marine conditions, the device is equipped with a cassette 45 that selects the length of the groove 29 when pulling it out of the package.

Thirdly, the gripping jaws 28 have their additional stroke, which reduces the path length of the carriage 26 in the inventive device. .

Fourthly, a simplified mechanism 2 feed sleeve film. It eliminated convex and concave rollers, laborious in manufacturing. Reduced the number of cylindrical rollers.

All this provides a reduction in the overall dimensions of the device, improves the quality of packing objects, and also increases its reliability in operation by eliminating damage and distortions of the film in the process of pulling the sleeve onto the object.
