DD239189A1 - LIFTING DEVICE FOR STACKS OF PLAN PARALLEL QUADER-FOAM STACKING ELEMENTS WITHOUT INTERMEDIATE BARS - Google Patents

Abstract

In known Entstapelungsvorrichtungen of this kind is unstacked from above, wherein the uppermost stacking element is unstacked from above by means of siphon. By the device according to the invention, the Kohaesionskraefte be repealed between the top and the following stacking element, so that a trouble-free unstacking can take place.

Description

Field of application of the invention

The unstacking device according to the invention is used in the singling of plane-parallel rectangular stack elements, which are constructed without intermediate strips.

Characteristic of the known technical solutions

In a known device of this type, the EntStapelung from above, wherein the uppermost stacking element is lifted by means of a siphon.

Due to the cohesive forces occurring between the stack elements, one to two further stack elements remain adhered to the raised stack element.

In addition, a device for stacking layers of stacks of layers (profiled timbers) is known, which moves the stack layer (profile wood) to a support element by means of a sliding device. By means of a hold-down the stack layer is pressed onto the support element. The support element, which is movable both vertically and horizontally, lifts the stack layer, then moves in the direction of a sliding device.

Support arms are then moved under the raised stacking position and moved to a stacking machine arranged next to the stack.

For this device, a large space is required and the technical solution very complicated.

Object of the invention

The object of the invention was the development of a simple design in the unstacking, for which a small space requirement is required.

Explanation of the essence of the invention

The technical object of the invention was to provide a device which allows a EntStapelung planparalleler cuboid stacking elements from above by means of a siphon, with no cohesive forces between the element to be unstacked and the following element.

According to the invention the object is achieved in that laterally next to the stack, a horizontally movable cross slide is arranged and that on the opposite side is a rotatably mounted roller whose center is located below the lower edge of the uppermost stacking element.

The cross slide is formed as a profile, which tapers from a rectangular cross-section trapezoidal to a sliding latch.

embodiment

The stack 1 is raised by means of a lifting table 7 in each case the height of a stack element per Entstapelungstakt.

After completion of the stroke, the top stacking element 2 is pushed by means of a transverse slide 3 on a rotatably mounted roller.

Due to the trapezoidal taper of the cross slide 3, the stacking element following the uppermost stacking element, if necessary, is positioned for separation.

The lower edge 5 of the uppermost stacking element moves onto the rotatably mounted roller 4 and due to the further transverse movement performs a curved movement with the roller 4, so that a wedge-shaped air gap is formed and the cohesive forces between the uppermost stacking element 2 and the next following can no longer act , Thereafter, the uppermost stacking element is unstacked by means of siphon.

Claims (3)

Invention claim: 1. unstacking devices for stacks of plane-parallel cuboidal stacking elements without intermediate strip, characterized in that laterally next to the stack (1) a horizontally movable cross slide (3) is arranged and that on the opposite side a rotatably mounted roller (4), whose center point located below the lower edge of the top stacking element (2). 2. Entstapelungsvorrichtung according to item 1, characterized in that the cross slide (3) is designed as a profile which is reinforced by a rectangular front part trapezoidal to a rectangle. - (3)
