Abstract

Saw Bale DismantlerIt is designed to move layers of rust or other board materials in production lines, the equipment is composed of a lifting platform, scraper units and a support rail. The reciprocating squeegee units of the push bar have one-sided carrier beams lined up above the lifting platform. The grippers are connected to the push pin and connected to the drive chain. The device requires a considerably smaller working area compared to other dismounters.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention

When disassembling bales or playing timber, special equipment is used, usually consisting of a single unit * Known disassemblers with folding arms, where the moving chains with the carrier and the horizontal axis of the chain bear their own weight on the timber * Swinging arms are equipped with tilting * hydraulic lifting platform requiring a shaft to a depth of 3 meters below floor level * This equipment is only suitable for smaller lumber thicknesses is a system where, after folding down, the girders form the overflow edge *

The disadvantage of the above mentioned equipment is the fact that they are mostly space-intensive and construction-intensive * The width of the equipment is two - even more than the width of the timber bales *

These drawbacks are eliminated by a device according to the invention, comprising a separate lifting platform, a reciprocating rake unit and a support rail, in which at least one rake unit having a linear movement of the push bar has a one-sided support for the push bar carrier extending above the lifting platform. connected to the drive *

For longer materials two rake units are used, which can be interconnected by a continuous push bar. This bale disassembler can therefore be made up of a commercially available scissor lift platform, which is complemented by a rake unit which is dimensionally and structurally undemanding. The required area includes only the maximum area of the bale plus two smaller areas of the racks of the folding units * The device according to the invention is more versatile, since it is also useful for disassembling bales of large-area materials or bales of other flat materials stacked

BRIEF DESCRIPTION OF THE DRAWINGS In the accompanying drawings, an exemplary embodiment of a bale disassembler according to the invention is shown in FIG. Fig. 2 is a plan view of two rake units ·

The bale disassembler consists of a scissor lift 2 to which the lumber bundle 1 is conveyed. Two scraper units 3 are mounted along the lift platform 2 and on the opposite side a support bar 12, which may be part of the device to which the lumber layer is moved or · The lifting platform 2 gradually lifts the individual layers of the lumber bundle 1 above the support rail 12 and these layers are pushed together for further processing by the pressure rails 8 of the folding units 3. The carrier 7 is derived from the drive chain 6 with the chain wheels mounted in the horizontal plane, ie · with the vertical axis of rotation · Because the carrier 7; the carrier 7 is connected to the carrier 7 by a push bar 8, which can be height-adjusted on the carrier 7 in order to adjust the basic position with respect to the position of the carrier. The drive 10 of the drive chain 6 is mounted on the stand 4.

The reciprocating movement of the carrier 7 can also be derived from another drive element with a linear reciprocating movement, for example from a rack, a motion screw or a hydraulic cylinder. By using a rack or a hydraulic cylinder, the maximum dimensions of the device are increased.

In Fig. 2, there are two rake units 3 in a configuration suitable for longer materials. The push bars 8 of these feed units 3 can be replaced by a continuous push bar 11. Separate drives 10 for each feed unit 3 can be replaced by a common drive · For shorter materials, one folding unit 3 is sufficient. · For large-area materials, push bar 8 or 11 requires a suitable adjustment to flip back and limit the relative position of the material and bar.

-3The end positions of the reciprocating movement of the gripper · 7 can be adjusted according to the width of the saw timber JL. The function of the support rail 12 can also be replaced by a frame or other part of the device on which the sawn timber extends laterally.

The lumber or other material baler according to the invention is suitable for inclusion in mechanized or automated defective lines where transverse displacement in the production line is required.
