Abstract

The racking container according to the invention has individual racks (2, 2´) height-adjustable in the vertical guides (11) of the frame (1). The racks (2, 2´) are connected to each other by vertical folding rods (3). The upper rack (2´) is suspended on hinges (41) on winding drums (4) rotatable on the frame (1). The winding drum (4) is kinematically connected to a torque source. The winding drum (4) is kinematically connected to the auxiliary drum (5), the unwound part of the hinge (41) from the auxiliary drum (5) is longer than the unwound part of the hinge (41) from the winding drum (4).

Description

Rack magazine with reduced failure rate

Field of technology

The subject of the solution is a rack storage, as a part of warehouse management. The individual racks are height-adjustable in vertical guides in the frame and connected to each other by vertical folding rods. The upper rack is hung on hinges that can be wound on a winding drum rotatably mounted on a frame.

Prior art

Previously known rack conveyors, the individual racks of which are height-adjustable in the vertical guides of the frame and interconnected by vertical folding rods, are height-controlled by an electric motor. The upper rack is suspended on hinges windable on a winding drum rotatably mounted on a frame and the winding drum is operated by a crank or is kinematicly connected to an electric motor, the drive of which is controlled by an electric button, as described in CZ 29088. wear and tear. The individual shelves then collapse and are unmanageable. If the rack conveyor is brought to the assembly line, its operation is endangered due to the limited supply of assembled parts.

The essence of the invention

The shelf magazine according to the invention has individual shelves that are height-adjustable in the vertical guides of the frame. The individual shelves are connected to each other by vertical folding rods. The upper rack is hung on hinges that can be wound on a winding drum rotatably mounted on a frame. The winding drum is kinematically connected to a torque source. The winding drum is kinematically connected to the auxiliary drum, where the unwound part of the hinge from the auxiliary drum is longer than the unwound part of the hinge from the winding drum. When one of the hinges breaks, instead of the individual racks in the guides collapsing, they fall by the length by which the hinge from the auxiliary drum is longer. This guarantees the functionality of the rack magazine until all the assembled parts stored in it are removed.

It is advantageous if the winding drum is at least doubled. At least two parts are arranged on the sides above the vertical guides and an auxiliary drum is arranged between the pair of winding drums. In such an arrangement, the hinge from the auxiliary drum performs its function in the event of a failure of the hinge of any of the winding drums.

The simplest arrangement for transmitting torque to the winding drums and the auxiliary drum provides a solution when the winding drum and the auxiliary drum are set on a common shaft.

Explanation of drawings

In the accompanying drawing in Fig. 1, a rack failure magazine is shown, where an auxiliary drum is located between a pair of winding drums on a common shaft.

Examples of embodiments of the invention

The racking container according to the invention has individual racks 2, T height-adjustable in the vertical guides 11 of the frame 1. The racks 2, 2 'are interconnected by vertical folding rods 3. Upper rack

2 'is suspended on hinges 41 windable on winding drums 4 rotatably mounted on the frame 1. It is suitable to apply straps to the hinges 41, in particular for their stowage during winding and easy visual inspection of their wear. The winding drum 4 is kinematically connected to a torque source, which in this embodiment is formed by a manual crank drive. The winding drum 5 is kinematically connected to the auxiliary drum 5. The unwound part of the hinge 41 from the auxiliary drum 5 is longer than the unwound part of the hinge 41 from the winding drum 4. The winding drum 4 is at least doubled, two parts being arranged laterally above vertical guides. 11 and the auxiliary drum 5 is arranged between a pair of winding drums 4. The winding drum 4 and the auxiliary drum 5 are arranged on a common shaft 6.

The hinges 41 wound on the winding drums 4 are still in a tensioned state due to gravity acting on the racks 2, 2 /. In the event of wear of the hinges 41, when they may elongate or even break, the shelves 2, 2 'will fall in the part below the deformed hinge 41. The fall of the shelves 2, 2' is caught by the hinge 41 from the auxiliary drum 5. of the shelves 2, 15 2 is limited by the size of the added length of the unwound part of the hinge 41 from the auxiliary drum 5. Such an improved shelf hopper will allow the hinge 41 to complete its unloading in temporary mode and subsequently repair it out of the workplace.
