Description

Technical Field

[0001] The utility model relates to the technical field of assembly lines, in particular to a tray separation device. Background Art

[0002] Current automated production processes, particularly those involving pallet loading and conveying, lack an efficient device for separating stacked pallets. Traditionally, this process relies on manual separation of pallets, requiring workers to manually remove each pallet from the stack and feed it to the subsequent production line. This existing method not only significantly slows down overall production cycles, reducing production line efficiency and throughput, but also leads to significant labor consumption and increased costs.

[0003] Specifically, manual pallet separation is susceptible to factors such as worker fatigue and uneven operating speed, making it difficult to ensure consistent and stable production. Therefore, a device that can automatically and accurately separate pallets one by one is needed to replace the existing manual operation. Utility Model Content

[0035] Regarding the problems existing in the above-mentioned prior art, see Figure 1 This embodiment provides a pallet separation device for separating the pallet at the bottom of multiple stacked pallets. The pallet separation device mainly includes a platform 1, a first-type electric cylinder 2, a second-type electric cylinder 3, a third-type electric cylinder 4 and a movable support block 6 arranged on the platform. Each part will be described separately below.

[0036] The first type of electric cylinder 2 is connected to the platform 1 through a connecting block. In this embodiment, two groups of first type electric cylinders 2 are used, both of which are arranged on the same two sides of the stacked pallets and are arranged on both sides of the stacked pallets facing each other. The guide rods of the first type of electric cylinder 2 match the gap between the edges of the upper and lower adjacent pallets to ensure that the guide rods can be inserted into the gap of the edge of the pallet.

[0037] The second-type electric cylinder 3 is connected to the platform 1. This embodiment uses a group of second-type platforms 3, which are arranged on both sides of the stacked pallets. The second-type electric cylinder 3 is located between the two first-type electric cylinders 2 on the same side of the stacked pallets, and the second-type electric cylinder 3 is arranged along the direction in which the pallets are stacked.

[0038] The two third-type electric cylinders 4 are respectively connected to the guide rods of the two second-type electric cylinders 3. The third-type electric cylinders 4 on both sides of the stacked pallet are arranged facing each other. The guide rods of the third-type electric cylinders 4 are connected to the separation blocks 5. The cross-section of the separation blocks 5 is L-shaped, and the bent parts are smoothed.

[0039] Multiple movable support blocks 6 are located in pre-opened grooves on the platform 1 below the stacking pallet and are arranged in a rectangular shape. The movable support blocks 6 are located below the guide rod of the first type electric cylinder 2. When the support blocks are extended, the height from the platform 1 is greater than the height from the guide rod of the first type electric cylinder 2 to the platform 1.

[0040] The three types of electric cylinders are located on three horizontal planes to ensure the separation of the pallets.

[0041] Preferably, the device further comprises a limit block 7 with an L-shaped cross section, which is connected to the platform 1 and is respectively arranged at the four corners of the stacked pallets, to further ensure the stability of the stacked pallets after the pallets are separated and to ensure that the position of the pallets is relatively fixed.

[0042] Preferably, a through slot 8 is provided on the platform 1 to facilitate removal of the separated trays.

[0043] In this embodiment, the first type electric cylinder 2, the second type electric cylinder 3 and the third type electric cylinder 4 are implemented by commercially available products, and the movable support block 6 can be driven by commercially available electric cylinders, pneumatic cylinders, etc.

[0044] See also Figure 2-Figure 6 Schematic diagram of the tray separation device in five positions during a separation process.

[0045] See also Figure 2Before the formal separation, the first type of electric cylinder 2 is in the extended state, and the stacked pallet is supported by the guide rod of the first type of electric cylinder 2. The second type of electric cylinder 3 is in the extended (i.e., lifted) state, and the third type of electric cylinder 4 is in the retracted state. The movable support block 6 is located in the slot of the platform 1.

[0046] See also Figure 3 , the movable support block 6 rises from the slot and lifts the stacked pallet, the pallet is supported by the support block 6, and the first type electric cylinder 2 retracts.

[0047] See also Figure 4 The movable support block 6 stops after falling to a certain height, the first type of electric cylinder 2 extends, and the guide rod extends into the gap between the edges of the two adjacent pallets.

[0048] See also Figure 5 At the same time as the first type of electric cylinder 2 extends, the third type of electric cylinder 4 extends. The height of the separation block 5 is slightly larger than the height of the gap between the edges of the two adjacent pallets. The fixing point of the separation block 5 is located at the upper end of the L-shape, and a certain margin is left at the fixed position. The extension action of the third type of electric cylinder 4 drives the upper end of the separation block 5 to penetrate into the gap between the edges of the two pallets, and the lower end abuts against the edge of the pallet located on the lower side.

[0049] See also Figure 6 , the movable support block 6 falls into the slot of the platform 1. At this time, the stacked pallets are supported by the guide rod of the first type electric cylinder 2 while the second type electric cylinder 3 retracts, driving the separation block 5 to move downward to separate the bottom pallet. After separation, the second type electric cylinder 3 returns to the extended state and the third type electric cylinder 4 returns to the retracted state, completing a separation action.

[0050] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
