Description

Technical Field

[0001] This utility model relates to the field of pallet straightening technology, and in particular to a pallet straightening device. Background Technology

[0002] Pallets are typically used to transport semi-finished products in daily production and assembly workshops. Products are placed on pallets and positioned at predetermined locations, and then transferred from the pallets using robotic arms or similar devices. However, for special products such as panels and glass, it is inconvenient to readjust their position after they are placed on pallets. Therefore, the pallet needs to be positioned accurately when it is placed in the predetermined location to facilitate accurate picking by robotic arms or similar devices. In existing technologies, products placed on pallets are often heavy and require forklifts or similar equipment for transfer. Deviations can occur when placing the products in the predetermined location, and it is difficult to adjust the pallet position manually. This leads to inaccurate product transfer due to inaccurate pallet placement, or the need for an additional positioning device to locate the transferred products. This results in low production efficiency or increased production costs. Therefore, how to accurately position pallets is a problem that those skilled in the art need to consider.

[0025] First direction S1, second direction S2. Detailed Implementation

[0026] The present invention will be further described in detail below with reference to specific embodiments:

[0027] This utility model is applied to pallet alignment. A pallet carrying products is placed on a conveyor mechanism by a forklift or other transfer device. Driven by the conveyor mechanism, the pallet is conveyed along the first direction S1 until it stops when the sensor can no longer detect it. Then, the first and second alignment components, respectively, use the first and second limiting wheels to push the pallet in the second direction to complete the pallet's positioning in the second direction. Simultaneously, the third limiting wheel pushes the pallet in the first direction S1, causing the pallet to abut against the positioning wheel, thus completing the pallet's positioning in the first direction S1. For ease of explanation, as follows... Figure 1 As shown, the conveying direction of the conveying mechanism is taken as the first direction S1, and on the same plane, the direction perpendicular to the first direction S1 is taken as the second direction S2. Specifically:

[0028] A pallet straightening device includes a frame 1, a conveying mechanism 2 and a straightening mechanism 3, all mounted on the frame 1.

[0029] The conveying mechanism 2 includes two conveyor belts 21 with a first conveying direction S1 and a motor (not shown in the figure) that drives the two conveyor belts 21. In this embodiment, the two conveyor belts 21 are spaced apart, and the tray is placed on both sides of the two conveyor belts 21 respectively. The conveyor belts 21 are roller conveyor belts 21; the motor can be set to one, driving both conveyor belts 21 to move simultaneously, or it can be set to two, driving the two conveyor belts 21 to move synchronously and simultaneously.

[0030] The correction mechanism 3 includes a first correction component 31, a second correction component 32, and a third correction component 33.

[0031] Two first alignment components 31 are provided, symmetrically arranged on both sides of the conveying mechanism 2 in the first direction S1. Each first alignment component 31 includes a first mounting plate 311 connected to the frame 1 via a slide rail, first limiting wheels 312 connected to the first mounting plate 311, and a first driving device 313 connected to the frame 1 and capable of driving the first mounting plate 311. In the two first alignment components 31, the two first driving devices 313 respectively drive the first limiting wheels 312 to move towards each other in the second direction S2 to push against the pallet. The first limiting wheels 312 are located at the edge of the first mounting plate 311, so that when the two first limiting wheels 312 move towards each other, the first limiting wheel 312 contacts the pallet first, avoiding interference from the first mounting plate 311. The position of the first limiting wheels 312 on the first mounting plate 311 can be adjusted to accommodate pallets of different sizes.

[0032] Two second alignment components 32 are provided, symmetrically arranged on both sides of the conveying mechanism 2 in the first direction S1. Each second alignment component 32 includes a second mounting plate 321 connected to the frame 1 via a slide rail, second limiting wheels 322 connected to the second mounting plate 321, and a second drive device 323 connected to the frame 1 and capable of driving the second mounting plate 321. The two second alignment components 32 are driven by the second drive device 323 to move the second limiting wheels 322 towards each other in the second direction S2 to push against the pallet. The position of the second limiting wheels 322 on the second mounting plate 321 is adjustable to accommodate pallets of different sizes. The edges of the second limiting wheels 322 protrude from the second mounting plate 321, ensuring that the second limiting wheels 322 contact the pallet before the second mounting plate 321, thus avoiding interference.

[0033] The third guide component 33 includes a positioning wheel 331 and a third limiting wheel 332. The third limiting wheel 332 pushes the tray to move in the first direction S1 until it contacts the positioning wheel 331.

[0034] The third alignment component 33 includes a second limiting wheel 322 connected to the second mounting plate 321, a third driving device 333, and an arc-shaped bracket 334. One end of the third driving device 333 is rotatably connected to the second mounting plate 321, and the other end is rotatably connected to the middle of the arc-shaped bracket 334; one end of the arc-shaped bracket 334 is rotatably connected to the second mounting plate 321, and the other end is connected to the third limiting wheel 332. The third driving device 333 drives the arc-shaped bracket 334 to rotate along its connection with the second mounting plate 321, thereby driving the third limiting wheel 332 to rotate, and thus pushing the tray to move in the first direction S1. The third alignment component 33 also includes a positioning plate 335, and the positioning plate 335 and the positioning wheel 331 are both located at the same end of the conveying mechanism 2 in the first direction S1. Figure 3 The image shows the state of the third guide component 33 when it pushes against the tray, as shown. Figure 2 The image shows the state of the third alignment component 33 when it is reset. It should be noted that the third alignment components 33 on both sides move synchronously.

[0035] In this embodiment, a limit plate 22 and a sensor 23 are provided at one end of the conveying mechanism 2 away from the positioning plate 335 in the first direction S1. The limit plate 22 is connected to the frame 1 through the lifting device 221.

[0036] When the pallet is transported to the conveyor mechanism 2 by a forklift or other transport equipment, both ends of the pallet overlap the two conveyor belts 21 respectively. At this time, the sensor 23 can detect the pallet. Then the motor starts and transports the pallet along the first direction S1 until the sensor 23 can no longer detect the pallet and stops. The first drive device 313 and the second drive device 323 on both sides start simultaneously or in sequence, respectively driving the two first limit wheels 312 and the second limit wheels 322 to move towards each other, and abut against the pallet from both sides to the middle, completing the positioning of the pallet in the second direction S2. Then, the third drive device 333 drives the arc bracket 334 to rotate on the second mounting plate 321, thereby causing the third limit wheel 332 to abut against the pallet in the first direction S1, so that the other end of the pallet abuts against the positioning plate 335 or the positioning wheel 331, completing the positioning of the pallet in the first direction S1.

[0037] The positioning plate 335 is primarily designed to prevent forklifts and other transport equipment from directly contacting the positioning wheels 331 when placing the pallet, thus avoiding deformation of the positioning wheels 331. Therefore, in some embodiments, only the positioning wheels 331 may be provided. When the sensor 23 fails to detect the pallet, it indicates that the pallet is completely above the conveying mechanism 2. At this time, the lifting device 221 lifts the limiting plate 22 upwards, providing protection and preventing the pallet from falling off due to unforeseen circumstances.

[0038] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
