Lifting device for pallet goods

Abstract

The invention presents a solution that enables simple separation of individual boxes on a pallet, which is also easy to manufacture and therefore minimally prone to failure, and can also be operated manually. The core is a main mechanism embodied as a frame, on which telescopic rails for lifting boxes are movably attached. These rails are connected by lift templates, which can be implemented as a template, chain, or other sequentially lifting systems with grooves into which the movement pins of the telescopic rails extend. The telescopic rails feature at least two pins on the front side for engaging the transport box, e.g., an EPP box. The main mechanism with the telescopic rails is movably mounted in the frame.

Description

DescriptionTitle of Invention: Lifting Device for Pallet GoodsTechnical Field

[0001] The invention relates to a device for simple lifting and sliding out of stackable boxes placed on a pallet.Prior State of the Art

[0002] Currently, certain types of goods or products are transported using boxes that are stacked on top of each other on a pallet, forming a transport unit. The individual boxes preferably interlock, creating a relatively stable unit on the pallet. The problem arises when the pallet with the boxes reaches its destination and the goods or products need to be removed from the boxes. This can only be done by removing the topmost box, setting it aside, and then extracting the product. Another method involves removing the product first and then taking the box aside. This process is repeated until all the stacked boxes on the pallet are uncovered, i.e., until the transport unit is disassembled. This method is space-intensive, requires extensive handling of boxes, and involves significant manual labor since the empty boxes must be stacked back onto the pallet.

[0003] A search for known solutions revealed EP 3215451 titled “Lifting Device for Pallet Goods” and EP 2316758 titled “Pallet Conveyor Device”, which both represent the state of the art and do not compromise the novelty of the present solution. Another relevant solution is utility model UV 36391, where a scissor mechanism is used to separate individual boxes.Disclosure of the technical solution

[0004] The goal is to find a solution that allows simple separation of individual boxes on a pallet, is easy to manufacture, minimally prone to malfunction, and can be manually operated.

[0005] This goal is fulfilled by the lifting device described in this technical solution with the following structural configuration. The core is a main mechanism embodied as a frame, on which telescopic rails for lifting boxes are movably attached. These rails are connected by lift templates, which can be implemented as a template, chain, or other sequentially lifting systems with grooves into which the movement pins of the telescopic rails extend. The telescopic rails feature at least two pins on the front side for engaging the transport box, e.g., an EPP box. The main mechanism with the telescopic rails is movably mounted in the frame, allowing horizontal movement via a horizontal travel system to connect the pin with the box. The vertical movement of the telescopic rails is provided by a vertical travel system, which is movably connected to the frame. Attached to the vertical travel system is a travel arm, which is connected viaa clearance-defined lifting rod to the upper telescopic rail. The arm is also connected to a control mechanism, namely a winding shaft, which ensures the vertical movement of the telescopic rails and horizontal movement of the main mechanism with the lift templates. A cam is mounted on the vertical travel system, and due to its shape, enables the horizontal movement of the main mechanism, which is guided by the horizontal travel. Controlled movement is ensured via rollers. The entire mechanism is continuously pushed against the cam by springs to ensure its return motion.Brief description of drawing

[0006] The invention is further explained using drawings, where Fig. 1 schematically depicts the entire device, and Fig. 2 shows a cross-section of the device.Modes for carrying out the technical solution

[0007] The device consists of a frame (1), in which a main mechanism (4) is placed. Telescopic rails (10) for lifting boxes are movably mounted on it and are connected by lift templates (11), in this specific example realized as guide rails with grooves (12), into which movement pins (13) of the telescopic rails (10) extend. Each telescopic rail (10) has two front-side pins (14) for engaging a transport box, in this case, an EPP box. The main mechanism (4) with the telescopic rails (10) is movably mounted in the frame (1), allowing horizontal movement via the horizontal travel system (3) to engage the pin (14) with the box. Vertical movement is provided by the vertical travel system (2), which is movably attached to the frame (1). Attached to the vertical travel (2) is a travel arm (6), to which a clearance-defined lifting rod (9) is connected, with its other end fixed to the upper telescopic rail (10). The arm (6) is also linked to a control mechanism (5), a winding shaft, that ensures both vertical movement of the telescopic rails (10) and horizontal movement of the main mechanism (4) with the lift templates (11). A cam (7) is fixed on the vertical travel system (2), which, due to its shape, enables the horizontal movement of the main mechanism (4), guided via the horizontal travel (3). Controlled movement of the mechanism (4) is ensured via rollers(8). The entire mechanism (4) is pressed against the cam (7) by springs (15) to ensure return motion.

[0008] The device functions as follows: A pallet with boxes is inserted into the frame (1). The winding shaft (5) and the connected arm (6) initiate vertical movement of the vertical travel (2), which, via the cam (7), horizontally shifts the main mechanism (4) with the telescopic rails (10) toward the boxes so that pin (14) is inserted into a hole in the box. As the vertical movement of the vertical travel (2) continues, the lifting rod(9) activates the telescopic rails (10), which gradually lift the boxes using grooves (12), creating space between the boxes. Thanks to the telescopic rails (10), any box can be pulled out like a drawer or easily removed.Industrial Applicability

[0009] The invention can be used across virtually all industrial sectors.
