Description

Technical Field

[0001] The utility model relates to the technical field of tray disassembly, in particular to a tray disassembly mechanism. Background Art

[0002] With the rapid development of e-commerce and modern logistics, goods are generally mechanically classified and transported through a large number of pallets in logistics warehouses. As the basic carrier of goods transportation, the efficiency of loading, unloading, storage and distribution of pallets directly affects the cost and efficiency of the overall supply chain. In order to facilitate pallet handling and reduce the space occupied by pallets, empty pallets are usually stacked in stacks, and the stacks of pallets need to be separated when used. The current operation of splitting pallets is mainly achieved manually, which is relatively inefficient.

[0003] At present, a Chinese utility model patent with patent publication number CN104986577A discloses an automatic pallet splitting system. This scheme disassembles the stacked pallets one by one by setting two pairs of ratchets that rotate in coordination. When splitting the pallets, no friction will be generated between the pallets, and no components such as travel switches are required. The structure is simple and the system has high stability. However, in the actual production process, the splitting system cannot freely adjust the splitting position according to the height position of the pallet, resulting in a small range of use and inability to adaptively split the pallets according to the type and specifications of the pallets. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A pallet dismantling mechanism comprises an installation box, in which a dismantling guide rod assembly for dismantling the pallet and a dismantling lifting assembly for adjusting the height position of the dismantling guide rod assembly are arranged, one end of the dismantling guide rod assembly abuts against the pallet, and the other end is transmission-connected to the dismantling lifting assembly; the dismantling guide rod assembly comprises a bracket guide rod, a linear bearing and a dismantling motor, one end of the bracket guide rod is rotationally connected to the linear bearing, and the other end extends out of the installation box; the linear bearing is transmission-connected to the dismantling flag cylinder via a connecting plate, and under the action of the dismantling motor, the bracket guide rod is driven to freely extend and retract to complete the dismantling of the pallet.

[0007] Preferably, the pallet-removing lifting assembly includes a lifting bracket, a lifting guiding member connected to the lifting bracket, and a driving motor drivingly connected to the lifting guiding member. A fixing plate is connected to the top end of the lifting bracket, and a fixed support is provided at the bottom end of the lifting bracket. A synchronous belt transmission assembly is connected between the driving motor and the lifting guiding member. The lifting guiding member is movably connected to the pallet-removing guide rod assembly.

[0008] Preferably, the lifting guiding member includes a lifting guide rail, a lifting screw rod, and a lifting plate. The lifting guide rail is arranged on the lifting bracket, and a slider is connected between the lifting guide rail and the lifting plate. The slider is slidably connected to the lifting guide rail. The lifting screw rod is arranged parallel to the lifting guide rail, and one end of the lifting screw rod is rotationally connected to the synchronous belt transmission assembly. A nut seat is connected between the lifting screw rod and the lifting plate, and the nut seat is slidably sleeved on the lifting screw rod.

[0009] Preferably, the lifting plate is slidably connected to the lifting guide rail and the lifting screw rod through the slider and the nut seat, and a pallet-removing motor and a linear bearing are fixedly connected to the lifting plate to drive the pallet-removing guide rod assembly to slide up and down.

[0014] In summary, the beneficial effects of the present utility model are as follows:

[0015] The utility model realizes the sequential splitting and conveying of the trays at the bottommost layer of the tray group to be split through the cooperative transmission of the tray-splitting guide rod assembly and the tray-splitting lifting assembly built in the tray-splitting mechanism, thereby achieving the rapid and orderly splitting of the trays, reducing the waste of manpower and improving the splitting efficiency. Among them, the tray-splitting lifting assembly can automatically control and adjust the splitting height of the tray-splitting guide rod assembly according to the height of the tray. When the tray-splitting guide rod assembly reaches the specified splitting height, the linear bearing is controlled by the tray-splitting motor to extend out of the bracket guide rod until the bracket guide rod is inserted into the gap between the bottommost tray and its upper tray.

[0025] The following is combined with Figures 1-4 , an embodiment of a tray removal mechanism of the utility model is further described in detail.

[0026] A tray disassembly mechanism, such as Figure 1 , 2 As shown, it includes an installation box 2, in which a dismantling guide rod assembly 3 for dismantling the tray and a dismantling lifting assembly 4 for adjusting the height position of the dismantling guide rod assembly 3 are arranged. One end of the dismantling guide rod assembly 3 abuts against the pallet, and the other end is transmission-connected to the dismantling lifting assembly 4; the dismantling guide rod assembly 3 includes a bracket guide rod 31, a linear bearing 32 and a dismantling motor 33, one end of the bracket guide rod 31 is rotationally connected to the linear bearing 32, and the other end extends out of the installation box 2; the linear bearing 32 is transmission-connected to the dismantling flag cylinder through a connecting plate 34, and under the action of the dismantling motor 33, the bracket guide rod 31 is driven to freely extend and retract to complete the dismantling of the tray.

[0027] Specifically, the pallet removing mechanism is symmetrically arranged at both ends of the pallet feeding ground belt 1, so that the two sides of the pallet can be supported and split simultaneously. First, the pallet group to be split is conveyed between the two pallet removing mechanisms through the pallet feeding ground belt 1. Through the cooperation and transmission of the pallet removing guide rod assembly 3 and the pallet removing lifting assembly 4 built in the pallet removing mechanism, the pallet at the bottom of the pallet group to be split is split out, and the single split pallet is continuously conveyed to the next process through the pallet feeding ground belt 1; during the pallet removing process, the pallet removing lifting assembly 4 can automatically control and adjust the splitting height of the pallet removing guide rod assembly 3 according to the height of the pallet. After the pallet removing guide rod assembly 3 reaches the specified splitting height, the linear bearing 32 is controlled by the pallet removing motor 33 to extend out of the bracket guide rod 31 until the bracket guide rod 31 is inserted into the gap between the bottommost pallet and its upper pallet. The bracket guide rod 31 holds the upper pallet and rises until the upper pallet is separated from the bottommost pallet; after the bottommost pallet is conveyed away, the pallet removing lifting assembly 4 controls the pallet removing guide rod assembly 3 to descend until the bottommost pallet falls onto the ground conveying chain, and the bracket motor reverses to control the bracket guide rod 31 to retract, and the pallet removing mechanism returns to the initial state, waiting for the next pallet removal.

[0028] In this embodiment, as Figures 2-4 shown, the pallet removing lifting assembly 4 includes a lifting bracket 41, a lifting guiding member 42 connected to the lifting bracket 41, and a driving motor 43 drivingly connected to the lifting guiding member 42. A fixing plate 5 is connected to the top end of the lifting bracket 41, and a fixed support 6 is provided at the bottom end of the lifting bracket 41; a synchronous belt 93 transmission assembly 9 is connected between the driving motor 43 and the lifting guiding member 42; the lifting guiding member 42 is movably connected to the pallet removing guide rod assembly 3.

[0029] Specifically, a distance detection bracket is further provided at one end of the lifting bracket 41. A plurality of square holes are formed in the distance detection bracket. By using the distance detection bracket, the lifting distance can be controlled, and thus the pallet removing position of the pallet removing guide rod assembly 3 can be accurately controlled; among them, the lifting guiding member 42 includes a lifting guide rail 421, a lifting screw 422, and a lifting plate 423. The lifting guide rail 421 is arranged on the lifting bracket 41, and a slider 424 is connected between the lifting guide rail 421 and the lifting plate 423. The slider 424 is slidably connected to the lifting guide rail 421; the lifting screw 422 is arranged parallel to the lifting guide rail 421, and one end of the lifting screw 422 is rotationally connected to the synchronous belt 93 transmission assembly 9. A nut seat 425 is connected between the lifting screw 422 and the lifting plate 423. The nut seat 425 is slidably sleeved on the lifting screw 422. The lifting plate 423 is slidably connected to the lifting guide rail 421 and the lifting screw 422 through the slider 424 and the nut seat 425, and the pallet removing motor 33 and the linear bearing 32 are fixedly connected to the lifting plate 423 to drive the pallet removing guide rod assembly 3 to slide up and down.

[0030] In this embodiment, as Figure 3As shown, buffer pads 7 are provided at the positions of the fixed plate 5 and the fixed support 6 corresponding to the lifting plate 423, and the buffer pads 7 are made of rubber pads.

[0031] Specifically, when the lifting plate 423 slides along the lifting guide rail 421 and the lifting screw 422, in order to prevent the lifting plate 423 from colliding with the fixed plate 5 and the fixed support 6 when it slides to the maximum stroke position, buffer pads 7 are provided to buffer the impact force of the lifting plate 423, thereby preventing the unpacking position of the unpacking guide rod assembly 3 on the tray from shifting during the collision. The purpose of using rubber pads is that flexible materials can better absorb the impact force and achieve a good buffer and shock absorption effect.

[0032] In this embodiment, as Figure 2 shown, a proximity switch 8 for controlling the sliding stroke is further provided at the bottom end of the lifting plate 423.

[0033] Specifically, by using the proximity switch 8 in cooperation with the distance detection frame, the lifting position of the unpacking and lifting assembly 4 is controlled, so that the unpacking position of the unpacking guide rod assembly 3 can be detected in real time, enabling the unpacking position of the tray to be accurately identified during unpacking, thereby improving the unpacking efficiency.

[0034] In this embodiment, the synchronous belt 93 transmission assembly 9 includes a lifting driving wheel 91, a lifting driven wheel 92 and a synchronous belt 93. The lifting driving wheel 91 is sleeved on the output end of the driving motor 43, the lifting driven wheel 92 is sleeved on the lifting screw 422, and the synchronous belt 93 is sleeved between the lifting driving wheel 91 and the lifting driven wheel 92.

[0035] Specifically, during the lifting process, in order to enable the driving motor 43 to control the lifting of the lifting guide member 42, the driving force of the driving motor 43 is transmitted to the lifting screw 422 by using the synchronous belt 93 transmission assembly 9, thereby controlling the lifting position of the lifting screw 422 and further adjusting the splitting height of the unpacking guide rod assembly 3.

[0036] In this embodiment, an unpacking baffle 10 is provided at the position of the mounting box 2 corresponding to the unpacking guide rod assembly 3. A strip-shaped guide groove 101 is formed on the unpacking baffle 10, and the bracket guide rod 31 moves up and down along the direction of the strip-shaped guide groove 101.

[0037] Specifically, the installation box 2 can function as a protective cover to prevent the internal pallet removal lifting component 4 and the pallet removal guide rod component 3 from being impacted. At the same time, since the installation box 2 is connected to the incoming pallet guide rail, in order to limit the extended position of the pallet guide rod 31, a pallet removal baffle 10 is provided at the position of the installation box 2 corresponding to the pallet guide rod 31 for limitation. And in order not to affect the extension of the splitting guide rod, a strip-shaped guide groove 101 is opened on the pallet removal baffle 10, so that the pallet guide rod 31 can move up and down along the strip-shaped guide groove 101 during lifting, thereby completing the work of splitting the pallet.

[0038] Working principle of the present utility model:

[0039] When the forklift places the whole pallet on the ground conveyor chain and the staff sets the height of the pallet, according to the height of the pallet set by the staff, the drive motor 43 rotates clockwise to drive the synchronous belt 93 and the transmission component 9 to rotate together, thereby driving the lifting screw rod 422 to rotate and driving the nut seat 425 to rise. Thus, the lifting plate 423 and the proximity switch 8 are driven to rise. When the proximity switch 8 passes by the distance detection frame, a signal is input. When passing through the square hole on the distance detection frame, no signal is input. According to the time of signal input and non-input of the proximity switch 8, the rotation speed of the drive motor 43, and the lead of the lifting screw rod 422, the rising distance of the lifting plate 423 is calculated, so as to set the height required for the lifting plate 423 to support the second-to-last pallet. Then the pallet guide rod 31 extends, and the pallet guide rod 31 supports the second-to-last pallet to continue rising until the second-to-last pallet detaches from the last pallet. After the last pallet is conveyed away, the drive motor 43 rotates counterclockwise, the lifting plate 423 descends until the second-to-last pallet falls onto the ground conveyor chain, the pallet cylinder extends, the pallet guide rod 31 retracts, and the mechanism returns to the initial state, waiting for the next pallet removal.

[0040] The embodiments of the present specific implementation manners are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. The same components are denoted by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
