5. The device according to claim 1, characterized in that it is provided with a locking mechanism comprising a bar hinged on the cassette for interacting with the limit switch.

12 (one sleeve not shown) that can move along the guides 13. Two platforms 14 can be hingedly attached to the sleeves 12, consisting of

pivotally connected levers 15, axes 16, and axially mounted on axes with rotation, figured rollers 17 made of elastic material and having shaped grooves on the outside. Figured rollers hold the bottle in the position in which they were in the cassette. The platforms are interconnected by central levers 18 (one lever is shown) providing simultaneous change of the levels of the platform 14 to the extreme positions. The movement to the ejection mechanism 3 is set by chains 18 and 19 (one chain is shown), enveloping drive sprockets 20 and reversing sprockets 21 and articulated with central levers 18. Mechanism 4 orientation of bottles

may consist of a rotary platform 22 with valleys for fixing the bottles in a predetermined position, a curvilinear support 23 having a horizontal section capable of accommodating one row of blocks. The rotary platform is connected with the axis 24, on which the link 25, which can perform reciprocating movements with a stand, is fixed, interacting through the rocker stone 26 with the rod 27, fixed on the sleeve 12 and having a groove 28.

To return the rotary platform 22 to its original position, spring 29 is installed. The wire cutting mechanism 6 consists of two blades 30, in the shanks of which there are grooves 31. The blades are interconnected and the pusher 32 axle 33. At the end

the pusher is fixed to the roller 34 which engages with the cam 35. The pusher 32 is mounted for longitudinal movement in the guide 36 fixedly mounted on the bracket 37. The stops 38, which are also included in the slots 31 of the blades 30, are also fixed on the bracket 37.

The wire removal mechanism 8 may consist of a drive drum 39 and a pressure drum 40, which are mounted on shafts 41 and 42 and consist of two parts, between which the clamps 43 fixed by screws 44 through rings 45 are mounted with the possibility of rotation relative to the shafts 41 and 42. to sprockets 46, mounted on bearings 47. Grippers 43 can reciprocate with oscillating motion, chains 48, sprockets 49, gears 50 and gear racks 51, at the ends of which are fixed rollers 52 which are in engagement with cams 53. The presser the drum 40 by means of the spring 54 is pressed against the drive drum 39.

In order to prevent the package of bottles connected with wire from entering the ejection zone, there is a locking mechanism, which is a bar 55, which is hinged on the cassette 1 and interacts with the limit switch 56.

The common drive of the device consists of an electric motor 57, a gear 58, which transmits torque to the shaft 59.

The torque from the shaft 59 to the drive sprocket 20 of the ejection mechanism is transmitted via sprockets 60, chains 61, sprockets 62.

The cams 35 of the wire cutter are driven from sprocket 21 by an asterisk 63, a chain 64, an asterisk 65, and a pair of bevel gears 66.

The cam 53 of the wire removal mechanism is driven from the shaft 59 by means of an asterisk 67, a chain 68 and an asterisk 69. The drum 39 is driven by an autonomous electric motor (not shown).

Conveyors 5 tap bottles are equipped with guides 70.

The device works as follows.

The bottle package is fed to the cassette 1. At the time when the bag is stationary and the bottles 2 are in the position shown in FIG. 9 and 10, the cam with its protrusion rolls onto the roller 34, thereby moving the pusher 32 with the blades 30. The insertion of the blades into the cassette is accompanied by their simultaneous closure due to the fixed stops 38, as a result of which the wire 7 is cut.

The cut wire of the gripper 43 through the groove 10 is removed from the cassette 1 and inserted between the rotating drums 39 and 40.

After the wire is pinched by the reels, the gripper 43 returns to its original position, and the wire carried by the reels is completely removed from the cassette. The second turn of the wire is removed in a similar manner with the aid of a gripper 43 mounted on the shaft of the pressure drum 40, after the bag is lowered onto one row of bottles. An autonomous drive of the drums, which provides a greater speed of rotation of the drums compared to the hooks, as well as alternately switching on the hooks 43, eliminates the entanglement of the wire.

The bottles 2 released from the wire 7 do not fall apart due to the shape of the cassette.

Firstly, the bottom is lowered into the zone of operation of the ejection mechanism 3, which pushes the row out of the cassette 1 by the ejector bar 11 and is moved by the rollers 17 of the platforms 14 (Figures 2, 3 and 4). Another set of bottles

0 is first supported by the pushing bar 11, and then by the platform 14 moving after the pushing bar. At the end of the stroke of the bumper bar, platform 14 smoothly lowers another row of bottles to subsequently shift them in the opposite direction, eliminating blows that can lead to a battle of the bottles. This is achieved by turning the central lever 18, which is pivotally connected to the platform 14 and the chain 19, which, when bending around the sprockets 20 and 21, carries the central lever, turning the latter. With chain 19 and central lever 18 ejector bar

II and the sleeve 12 is set to reciprocate along the guide 13.

The row of bottles pushed out of the cassette at the end of the stroke is lifted by the platform 14 and during the return stroke of the pushing bar 11 and the platform 14 slides from the platform to the turntable 22 of the mechanism 4 for orientation of the bottles, resting

0 while on the cassette 1 (Fig. 3 and 4). The turntable 22 begins to move only after the platform 14 leaves the area described by the turntable during movement (Fig. 4). With further movement of the turntable

 the row of bottles is transferred to the horizontal portion of the curvilinear support 23, while pushing out the previously installed row to the conveyor of removal of the bottles. Return the turntable to its original position

produced by the action of the spring 29.

The reciprocating movement with the platform of the turntable is carried out with the help of the rod 27, having a groove 28 and backstage with the rocker stone 26. 5 The device operates in automatic mode. When stopping the supply of packages of bottles to the cassette 1, the hinged plate 55 is retracted by the end spring
