Description

one

The invention relates to devices for stacking sheets in bags and can be used in industries where sheet materials are produced, in particular in cross-cutting and finishing units in the shops of metallurgical plants.

A device for stacking sheets is known, comprising a conveyor table and a lifting table for sheets 1 located between its rollers.

This device has poor performance.

In order to improve the performance of the device, the lifting stop is mounted on carriages with guides with the possibility of reciprocating movement relative to the carriages along the rollers by means of a pinion gear, one of the rails of which is fixed on the lifting table and others on the rails, while the rails are connected among themselves by means of the cogwheels installed on carriages.

FIG. shows the proposed device in the initial position, the cross-section; in fig. 2 - the same, at the moment when the sheet is raised above the level of the roller table and shifted to the side above the left pocket; in fig. 3 - the same, at the time of rolling and laying the sheets in the pocket; in fig. 4 shows section A-A in FIG. ; in fig. 5 is a device in plan view.

The device consists of a lifting table made in the form of beams, carrying idle rollers 2 on top of them. Beams 3 are arranged in rows between the rollers of the transport roller table 3, From the bottom of the beam, there are guide rails that interact with the support rollers 4. The rollers 4 are mounted into movable carriages 5, which are moved by the actuator 6, for example, through a chain transmission. Carriages are supplied, except TOGO; rollers 7 interacting with guide beams 8. The ends of the beam 8 are hingedly attached to two hydraulic lifts 9 having individual power supply and control systems of hydraulic nets.

The movable carriages 5 are mounted with idle gears O interacting simultaneously with two rails of the upper 11 attached to the beam 1 and the lower 12 attached to the beam 8. The sheets 13 are placed in two pockets 14 that are mirrored to each other relative to the axis of symmetry of the roller table. The proposed device works as follows: In the initial position, the lifting table transfer beams are located between the roles of the transport roller table 3, while the beams are arranged horizontally and the idle rollers 2 are recessed below the level of s roller table. In this position, the ball sheet 13 is freely transported by the roller table to the stacking area. In the predetermined position the roller table is stopped along with the sheet. The hydraulic lifts 9 are turned on up, at the same time the carriages 5 and the transfer bins 1 are lifted simultaneously. The upstroke is chosen such that the idle rollers 2 raise the sheet above the roller table. Include the drive b and move the carriage 5 in the direction of full-time from the pockets. When moving the carriages 5, a gear consisting of wheel 10 and rails 11, 12 comes into operation. The gear is mounted on carriages, so the mobile rail receives translational motion in the same CTOpoiry. that the carriage, In this case, the course of the transfer beams 1 will be 2 times larger than the carriage stroke. This condition is fulfilled in view of the fact that the center of the gear wheel 10 is connected with the carriage, and the rail 11 receives a double increase in speed due to the relative movement of the teeth of the wheel. When the sheet reaches the zone of the pockets 14, one of the lifts 9 is lowered, respectively, and the sheet under the action of its own weight rolls over the idle rollers 2. The final stop of the sheet is limited to the side stops of the pockets. After this, the carriages 5 with the transfer beams 1 are returned to their original position by means of the actuator 6, the sheet rolls off the rollers 2, lowers and stacks into the stack. Then, the other side of the guide rails 8 is lowered, and the sheet stacking cycle is repeated. Laying sheets in another pocket made in the same sequence. Introduction to the device of a movable carriage mounted on guides and carrier transfer beams, and implementation of the mechanism for moving each beam in the form of a rack and pinion gear consisting of two rails, one of which is fixed on the transfer beam and the other on the guide and gear wheel installed in the carriage, reduces the weight and size of the device. For example, the weight of a device for stacking large sheets with a length of 40 m and a width of 4.5 m will be almost half the size of existing devices. Formulas The device for stacking sheets, containing} a roll table and a lifting table for sheets between its rollers, characterized in that, in order to improve the performance of the device, the lifting table is mounted on carriages with reciprocating moving relative to the carriages along the rollers by means of a slatted gear before .gl; One of the slats of which are fixed on the lifting cn-ojie, and others on the guides, when the axes are connected to each other by means of gear wheels mounted on carriages.
