Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 2The non-powered pallet collection system in this embodiment includes a frame 1, a slide 2 fixed on the top of the frame 1, a feeding component 3 for receiving pallets on the slide 2, a feeding component 4 for conveying pallets on the inner side of the frame 1 and below the feeding component 3, two conveyor chains 5 located on the front and rear sides of the feeding component 4 respectively on the frame 1, four placement rods 6 fixed on the top of the frame 1, right angle plates 7 fixed on the left side of the two left placement rods 6, a movable plate 8 hinged to the inner side of each placement rod 6, and a limiting plate 9 fixed to the inner side of each placement rod 6.

[0025] In addition, the feeding assembly 3 includes a front frame 301 movably connected to the right side of the slide 2, and a rear frame 304 movably connected to the left side of the slide 2. The slide 2 is used to limit the front frame 301 and the rear frame 304, thereby ensuring that the front frame 301 and the rear frame 304 move stably under the action of the connecting chain 303. The inner side of the slide 2 is rotatably connected to two stabilizing sprockets 302 through bearings. The stabilizing sprockets 302 change the direction of movement of the connecting chain 303, thereby ensuring that the rear frame 304 moves in the opposite direction to the front frame 301. Two connecting chains 303 are fixed to the top of the front frame 301. The two connecting chains 303 pass around the two stabilizing sprockets 302 respectively. The other end of the two connecting chains 303 is fixed to the rear frame 304. The bottom of the rear frame 304 is provided with a rotating part 305. When the upper part of the rotating part 305 contacts the pallet, it can provide good support for the pallet. When the lower part of the rotating part 305 contacts the pallet, it will fold, thereby ensuring that it will not interfere with the pallet.

[0026] It should be further explained that the bottom of the rear frame 304 is provided with a through slot for the pallet to pass through smoothly, and the bottom of the front frame 301 is provided with a connecting slot for the pallet to pass through smoothly. Both the through slot and the connecting slot are used to ensure the smooth passage of the pallet. The rotating part 305 includes an abutment seat 3051 fixed to the bottom of the rear frame 304. A lifting plate 3052 is hinged to the inner side of the abutment seat 3051. The bottom of the lifting plate 3052 abuts against the inner bottom wall of the abutment seat 3051. The abutment seat 3051 plays a partial limiting role. By limiting the lifting plate 3052 in one direction, the smooth and stable operation of the device is ensured.

[0027] In addition, a primary torsion spring is provided between the lifting plate 3052 and the abutment seat 3051, and a secondary torsion spring is provided between the movable plate 8 and the placement rod 6. The primary and secondary torsion springs can ensure that the lifting plate 3052 and the movable plate 8 can smoothly return to their original positions without external force. Multiple rollers are rotatably connected to the front frame 301 through bearings, and all the rollers extend outside the front frame 301.

[0028] In this embodiment, through the design of the loading component 3, the pallet can be quickly and smoothly transferred from the loading position to the feeding component 4, reducing manual intervention and improving loading efficiency. In particular, the cooperation between the front frame 301 and the rear frame 304, as well as the transmission of the stabilizing sprocket 302 and the connecting chain 303, makes the pallet loading process smoother.

[0029] Please see Figure 1 , Figure 3 and Figure 4 To facilitate subsequent pallet placement, the feeding assembly 4 in this embodiment includes two limiting rods 404 fixed to the front and rear side walls of the inner side of the frame 1, respectively. A connecting rod 403 is movably connected between the two limiting rods 404. The limiting rods 404 are mainly used to limit the connecting rod 403 and improve the stability of the connecting rod 403. Both limiting rods 404 pass through the connecting rod 403. Two transmission parts 405 are provided on the right side of the connecting rod 403. A swing frame 401 is also fixed on the right side of the connecting rod 403. The swing frame 401 serves as a connection. A trolley push plate 402 is fixed on the top of the swing frame 401.

[0030] Furthermore, each transmission unit 405 includes a small sprocket 4051 rotatably connected to the inner wall of the frame 1 via a bearing. A transmission chain 4052, passing over the small sprocket 4051, is fixed to the right side of the connecting rod 403. A tension sprocket 4053 is rotatably connected to the inner side of the frame 1 via a bearing. A stabilizing sprocket 4054, located to the left of the tension sprocket 4053, is rotatably connected to the inner side of the frame 1 via a bearing. A reversing sprocket 4055 is rotatably connected to the inner side of the frame 1 via a bearing. The transmission chain 4052 is sequentially... Passing above the tension sprocket 4053 and below the stabilizing sprocket 4054, the transmission chain 4052 bypasses the reversing sprocket 4055. The complex transmission structure of the transmission unit 405, through the reasonable arrangement of the tension sprocket 4053, the stabilizing sprocket 4054 and the reversing sprocket 4055, ensures the stable operation of the transmission chain 4052, reduces the risk of chain loosening or falling off, and improves the reliability of the system. A counterweight 4056 is fixed at the end of the two transmission chains 4052 away from the connecting rod 403.

[0031] In addition, the bottom of each movable plate 8 abuts against the limiting plate 9, and the rotating part 305 is located inside the multiple movable plates 8 and maintains a certain distance from the multiple movable plates 8. By maintaining a certain distance between the rotating part 305 and the multiple movable plates 8, it can be ensured that when the rotating part 305 is flipped, it will not interfere with the multiple movable plates 8.

[0032] In this embodiment, the counterweight 4056 on the feeding assembly 4 and the transmission chain 4052 ensure that the trolley push plate 402 and the swing frame 401 can return to their original positions smoothly after the external force disappears, making it convenient for the next use.

[0033] Understandably, the entire system is compactly designed, with each component working together to make full use of the limited space. For example, the placement rod 6 and right-angle plate 7 not only provide a stable placement position for the pallet but also optimize the spatial layout, enabling the equipment to achieve efficient pallet collection and transportation functions in a small space.

[0034] The working principle of the above embodiments is as follows:

[0035] During operation, a forklift places the goods on the front frame 301. The front frame 301 descends under the weight of the goods and the action of the forklift, while the rear frame 304 rises. The front frame 301 touches the bottom and is in a horizontal position with the swing frame 401. The height of the trolley push plate 402 on the swing frame 401 is slightly lower than the top surface of the pallet. The forklift is started and then slowly drives towards the equipment and pushes the trolley push plate 402. The trolley push plate 402 pushes the pallet to the seat, and the goods fall onto the conveyor chain 5. At this time, most of the pallet is pushed to the left side of the equipment. While the forklift pushes the goods, the conveyor chain 5 works to automatically deliver the pallet to the set position. The forklift leaves, and at this time, the rear frame 304 is heavier than the front frame 301. The front frame 301 rises, and the rear frame 304 sinks. The movable plate 8 on the rear frame 304 passes over the pallet and automatically opens at the bottom of the pallet. When the front frame 301 descends with the next load and the rear frame 304 rises, the pallet is lifted. The pallet is collected by the movable plate 8, and the pallets are collected and stacked in a cyclical manner.
