Abstract

This invention relates to a rubber processing technique and is used for cutting bales. The goal is to increase the reliability of work. For this, each selection roller of the roller table is made in the form of coaxially arranged cylindrical segments. The boom stop is designed as mounted on the base in guide frames with spring-loaded pins. The pins are interposed between the lengths of the rolls of the roller conveyor and are associated with the drive of their translational mixing. 3 il.

The invention relates to the field of rubber processing and can be used for cutting natural and synthetic rubber bales.

The aim of the invention is to increase the reliability of operation.

FIG. 1 shows schematically the machine at the moment when the bale stops; in fig. 2 view A in FIG. one; in fig. 3 - the same. In the moment of rolling the cut piece of bale from the roller table.

The rubber bale cutting machine contains a guillotine knife 1 mounted on a base (not shown) connected to drive 2 by moving it along columns 3. Perpendicular to knife 1, a roller table 4 is installed with support table 5 and selection rollers 6. In the guides 7, with the help of projections and protrusions 8, the frame 9 is fixed. On the frame 9, stops are fixed in the form of glasses 10 with pins 11 inserted inside, the ends of which pass through the holes in the frame and protrude beyond the upper frame of the frame. The cups 10 are provided with longitudinal grooves 12, into which rods 13 are inserted, passing through the holes in the pins x 11. On the cups 10 are the raids of the spring 14, the lower ends of which rest against the frame 9, and the upper ends - into the rods 13. Between the upper frame bar 9 and the rods 13 are mounted with a traverse 15 fixed by the ends in the rods of the power cylinders 16 mounted on a base connected to the hydraulic movement of the knife (not shown).

To ensure the movement of the pins 11 relative to the rollers of the roller table 4 when measuring the length of the cut pieces from the pile 17, the selection rollers are made in the form of cylindrical sections between which the pins 11 are placed, and the cross bar 15 has grooves 18 allowing the glasses 10 to be moved relative to the traverse.

The operation of the machine is carried out as follows.

First set the required length of the piece cut from the bale. To do this, move the frame 9 along the guide rails 7 of the base. In this case, 1 t is moved between the lengths of the selection rollers 6 of the roller table 4 to the required distance from the line of movement of the knife 1. The grooves 8 on the cross-bar 15 allow the cups 10 to move relative to the cross-bar fixed on the cylinder rods 16. The cut bale 17 is set on the roller-table 4 and the bale under the action of its own weight moves along the roll table 4

until the stop are pins 11. Then the drive 2 is moved by moving the knife 1 and the knife cuts the pile 17. When the knife contacts the pile 17, the cylinder 16 is turned on, which moves down the yoke 15, and

. the latter, through the rods 13, moved in the grooves 12, lowers the pins II downward, freeing the cut piece, which rolls along the selection rollers 6.

After cutting the bale 17, the knife 1, under the action of the actuator 2, rises to its original position. At the same time, the cylinders 16 lift the yoke 15, and under the action of the springs 14 through the rods 13, the pins 11 are raised upwards. With the release of the knife 1 bale 17 last under its own weight moves along

0 to the roller table 4 until it stops at the pins 11. Then the cycle of operation is repeated.

If the piece is not cut with the knife 1 1, under the action of springs, they will either press the piece to the remaining pile 4 on the roller table 5 and do not allow the pile to move along the roller table 4 until the next cut, at which the final cutting of the piece from the pile occurs, or when the uncut piece is tilted on the qualifying rollers 6 pins under the action of springs 14,

0 moving upwards, they will lift the piece and tear it off from the main part of the bale. This design of the stop increases the reliability of the machine.
