Description

The invention relates to packaging equipment.

A device for bundling bales of piece goods, such as hides, is known, consisting of a receiving table with grooves for a continuous conveyor and suction cups for fixing products, a mechanism for forming bales, containing, supporting elements for folding the edges of the product, and a mechanism for tying bales connected with it by means of a stretcher conveyor.

In order to increase the performance and reliability of the device, it is proposed to support the elements in the work, and to spring and install the elements on the arms pivoting in the vertical plane. In this case, the elements should be placed at an angle below the plane of the table. Maintaining; elements can be made in the form of trellised nlosh, adok.

FIG. 1 shows a schematic representation of the proposed device, its general view; in fig. 2 is a section along the line A-A in FIG. one; in fig. 3 shows the node I in FIG. one; in fig. 4 is a section along BB in FIG. 2; in fig. 5 is a top view of the device.

The device consists of a receiving table 1 with grooves 2 for a conveyor 3, vacuum suction cups 4, a mechanism for forming bales, containing its supporting elements 5 s

springs 6 mounted on levers 7, mechanism 8 for tying up bales.

The receiving table 1 is folded onto the welded frame 9. On the welded frame 9, a vertical camshaft 10, a driving drum 11 of the conveyor 3, a bale wrapping mechanism 8 and two reels 12 with a polyethylene tape are fixed. Vacuum suckers 4 are connected to a vacuum system.

The supporting elements 5 of the forming mechanism are driven into the direction of the cams 13 and 14 through the tappets 15, gears 16, which are located on the same axis with the holder 17. The supporting elements 5 can

rotate around its axis.

The vertical cam shaft 10 is driven into rotation from the drive shaft 18 through a pair of bevel gears 19. Bevel

the gears 19 are fastened to the shaft 10 freely and locked onto it with the aid of a locking clutch 20. The drive shaft 18 is driven into rotation by the electric motor 21 via a belt drive 22.

Claims (2)

A conveyor belt 3, including drive drum 11, tension drum 23 and lifting roller bearings 24, is rotated by drive shaft 18 through a chain drive 25. The driving sprocket 26 of the latter is attached to the drive shaft 18 freely and locked onto it with a locking clutch 27. Lifting the supports 24 rotate around their axis from the cam 28 through the lever mechanism 29. The gland plate 30 of the bale wrapping mechanism 8 is attached by springs to the base plate 31, which is moved by means of a pneumatic cylinder 32. On the base plate there is a mechanism cooking polyethylene tape, which consists of two spring-loaded biasing the jaws 33 and 34 of the welding electrode mounted on the insulator 35. The forming and viscous bale tie is produced as follows. When the electric motor 21 is turned on, the drive shaft 18 rotates. The conical brush 19 and the drive sprocket 26 are unlocked, and therefore the cam shaft 10 and the conveyor 3 are in the state. The device operates as follows. The skin is placed on the receiving table 1 so that its edges hang down on the supporting elements 5. Then they turn on the forming mechanism. At this time, the suction cups 4 are connected to the vacuum system and hold the skin on the table. At the same time, the coupling 20 blocks the brush 19, and the cam shaft 10 makes one revolution. From the cams 13 and 14, the supporting elements 5 alternately move, which bend the cheek and form a rectangular bale. When the vertical cam shaft 10 makes a full revolution, the suction cups 4 are disconnected from the vacuum system and communicated with the atmosphere. At the same time, the lifting roller bearings 24 rotate from the cam 28 and raise the mites of the conveyor 3, and with it the molded bale above the table 1. Then the clutch 20 unlocks the jaw 19 and the camshaft 10 stops. After that, the clutch 27 is engaged, blocking the drive sprocket 26. Conveyor 3 starts to move and moves the bale. As it moves, the bale grabs the polyethylene tape and moves until it fits under the gland plate 30. At the same time, the polyethylene tape fits the bale on both sides. When the bale passes under the gland plate 30, it presses the sensor and the locking sleeve 27 unlocks the drive sprocket 26, and the conveyor 3 stops. Thereafter, pneumatic cylinder 32 is turned on, which moves the mechanism 8 upside down. When this gland plate 30 compresses the bale and tape. With further movement of the mechanism 8, wrapping down the jaws 33, compress the tape, and the hot electrode 34 melts it. In this case, the tape is cut and welded. The pneumatic cylinder 32 lifts the 8 binding mechanism. Claim 1. A device for packing in bales of threaded products, such as cheek, consisting of a receiving table with grooves for a stretcher conveyor and suction cups for fixing products, a mechanism for forming bales containing supporting elements for bending the edges of the product, and connected to The mechanism for tying bales through a conveyor, characterized in that, in order to increase the productivity and reliability of the device in operation, the supporting elements are spring loaded and mounted on levers , rotatable in a vertical plane, and located at an angle below the plane of the table. 2. A device according to claim 1, characterized in that the supporting elements are made in the form of lattice platforms.
