Description

Technical Field

[0001] This utility model relates to the field of pallet vertical lifting technology, specifically a pallet adaptive reciprocating vertical lifting device. Background Technology

[0002] Pallet vertical lifting devices are logistics and industrial equipment designed to achieve efficient vertical transfer of pallets and their materials. They are widely used in warehousing and logistics, manufacturing, e-commerce sorting, and other fields. Their core function is to break the spatial limitations of traditional horizontal transfer. Through mechanized and automated lifting mechanisms, they can smoothly and accurately transport pallets carrying workpieces and goods between different floors, shelf layers, or work platforms. They are one of the key pieces of equipment for building a three-dimensional warehousing system and improving space utilization and operational efficiency.

[0003] Current pallet vertical lifting devices generally suffer from poor material changing coordination, resulting in excessively long material changing times. Existing devices often perform workpiece transfer and material changing actions in steps, lacking efficient collaborative design: after the lifting pallet transports the workpiece to the target position, it must wait for the lifting component to complete a series of preparatory actions such as mechanical positioning and power transmission before it can receive the workpiece. During this process, the lifting pallet is idle and cannot immediately begin lifting the next workpiece. Furthermore, the transmission system design of traditional devices is flawed, often using single gear or chain drives, which not only results in high power transmission losses but also slow response speeds. The time interval between the lifting component's activation and the completion of workpiece reception is long, further extending the material changing cycle. This inefficient "transport-waiting-material changing" model leads to long intervals between single material changes and a long overall operation cycle, severely restricting the improvement of production and transfer efficiency.

[0006] Preferably, both the limiting crossbar and the supporting perforated plate have multiple through holes inside, which can limit the movement stroke of the supporting roller.

[0007] Preferably, an auxiliary slide bar is fixed on the side of the linkage crossbar away from the driving component, so that it can limit the movement stroke of the linkage crossbar in conjunction with the sliding support block.

[0008] Preferably, the limiting component includes a driving rotating rod, the sliding block has a driving rotating rod rotating inside, an eccentric block is fixed to the outer wall of one end of the driving rotating rod, sliding push rods are attached to both sides of the eccentric block, a driving wedge is fixed to one end of the sliding push rod, a limiting insert is attached to both sides of the driving wedge, and the limiting insert slides inside the sliding block.

[0009] Preferably, the limiting rod is fitted with a roller on one side of the driving wedge, which, together with the inclined surfaces on both sides of the driving wedge, can drive the limiting rod to move.

[0010] Preferably, the limiting rod is T-shaped, and a spring is provided at the bottom end of the T-shaped horizontal plate. The spring is a reset spring, and the other end of the reset spring is fixed to the inner wall of the sliding block. The elasticity of the reset spring can drive the limiting rod to reset.

[0011] Preferably, a slide rail is provided on one side of the top of the support rod, and multiple limiting holes are provided in the slide rail, which can limit the sliding block in conjunction with the limiting rod.

[0012] Preferably, the driving component includes a drive motor, the top of the sliding support block is fixed with the drive motor, the outer wall of the output shaft of the drive motor is fixed with a drive pulley, the outer wall of the drive pulley is wound with a linkage belt, the inner wall of the other end of the linkage belt away from the drive pulley is wound with a drive ring, and the internal thread of the drive ring has a translation screw.

[0013] Preferably, the outer wall of the drive ring is provided with a trapezoidal groove, which, together with the friction of the linkage belt, drives the drive ring to rotate.

[0014] Preferably, the drive ring has a through hole inside, and the through hole is provided with a thread that matches the outer wall of the translation screw, so that the translation screw can be moved by the thread transmission principle.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Through the coordinated design of "lifting pallet conveying - immediate support roller receiving", seamless connection between workpiece transfer and material change is achieved, fundamentally shortening the material change time. When the lifting pallet moves the workpiece to the target position at the top of the stable support frame, the drive unit can quickly respond and drive the support roller to complete the lifting action. After the drive motor starts, through the efficient transmission of the drive pulley, linkage belt, and drive ring, the power is precisely transmitted to the translation screw, driving the linkage crossbar and support roller to move quickly inward, rapidly fitting the bottom of the workpiece and forming stable support. The entire transmission process relies on the precision of the threaded drive and the rapid response characteristics of the belt drive, resulting in low power transmission loss and smooth action connection. The support roller has a short response time from start to completion of lifting, allowing it to immediately receive the workpiece after the lifting pallet reaches the designated position. This enables the lifting pallet to quickly descend for the next workpiece lifting operation without waiting, completely breaking the inefficient "conveyance-waiting-material change" mode of traditional devices and realizing continuous operation of "loading-receiving-unloading", significantly shortening the interval time of a single material change and the overall operation cycle.

[0017] To address the changing needs of workpieces of different specifications, the device is designed with a flexible and efficient pre-positioning adjustment mechanism, which significantly shortens the equipment debugging time before changing materials. The sliding block can move freely up and down along the slide rail of the supporting vertical rod, driving the limit crossbar and related drive components to adjust the height synchronously to adapt to the lifting and receiving needs of workpieces of different heights. During the adjustment process, only the drive rod needs to be rotated to control the insertion and locking of the limit plug and the limit hole of the supporting vertical rod through the linkage of the eccentric block, the sliding push rod and the drive wedge block, thus fixing the position of the sliding block. The design of the "T"-shaped limit plug and the return spring not only ensures the stability after positioning, but also makes the adjustment operation possible without the need for additional tools, which can be completed quickly by a single person. This convenient pre-positioning adjustment capability allows the device to quickly adapt to pallets and workpieces of different sizes and heights without the need for large-scale disassembly or debugging of the equipment, effectively reducing the preparation time when changing material changing scenarios and improving the efficiency of continuous material changing of multiple specifications of workpieces.
