Description

Technical Field

[0001] This utility model relates to a type of conveyor, specifically an adaptive pallet straightening conveyor. Background Technology

[0002] In automated packaging systems, pallets are a common conveying method. Pallets often become skewed during the conveyor line process. The angle of the pallets may vary due to differences in pallet size and loading methods, resulting in them not being accurately delivered into the automated warehouse.

[0003] Currently, when pallets deviate from their designated path, they are prone to rubbing against or getting stuck on the edge of the conveyor. This often leads to problems such as pallet jamming and motor overload during transport due to excessive friction. In addition, deviations in the position of pallets of different sizes on the conveyor can prevent them from being accurately transported to the designated location, affecting the normal transport of pallets.

[0017] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0018] like Figure 1-2As shown, an adaptive pallet straightening conveyor includes a conveyor frame 1. The top of the conveyor frame 1 has several sequentially arranged and parallel rollers 11. The bottom of the conveyor frame 1 has two parallel support rods 12 positioned below the rollers 11. A first guide plate 21, arranged along the length of the conveyor frame 1, is located at one edge of the conveyor frame 1 corresponding to one end of the roller 11. The first guide plate 21 is fixed to the edge of the conveyor frame 1, limiting one side of the pallet on the conveyor frame 1. A second guide plate 22, parallel to the first guide plate 21 and reciprocating along the axis of the roller 11, is located at the other edge of the conveyor frame 1 corresponding to the other end of the roller 11. The second guide plate 22 limits the other side of the pallet. Since the pallets vary in size, and the conveyor end has a material... If the pallet is misaligned during the conveying of the pallet by roller 11, it will not be able to accurately enter the silo. Pallets of different sizes will have different positions on roller 11. At this time, the second guide plate 22 can be activated, causing the second guide plate 22 to move towards the first guide plate 21. When the second guide plate 22 moves towards the first guide plate 21, it can push the misaligned pallet on roller 11 until both sides of the pallet abut against the side walls of the first guide plate 21 and the side walls of the second guide plate 22 respectively, and the pallet is close to the fixed first guide plate 21. Then the second guide plate 22 leaves the pallet, so that the pallet is close to the first guide plate 21 and is directly conveyed to the silo by roller 11. This effectively avoids the pallet from running off track and causing its position to shift on the roller, ensuring that the pallet can be accurately conveyed into the silo.

[0019] like Figure 1-3 As shown, the bottom of the second guide plate 22 is provided with multiple connecting blocks 221 extending to the bottom of the roller 11. There is a gap between the two rollers 11 to accommodate the connecting blocks 221. The multiple connecting blocks 221 at the bottom of the second guide plate 22 pass through the gap between the two rollers 11, extend to the bottom of the roller 11 and connect with the slider 222. The top of the support rod 12 is provided with multiple guide rails 13 arranged along the axial direction of the roller 11. The bottom of the connecting block 221 is provided with a slider 222 that slides with the guide rail 13. The guide rail 13 and the slider 222 cooperate so that the slider 222 can slide along the guide rail 13, thereby slidingly supporting the second guide plate 22. This allows the second guide plate 22 to move stably and smoothly, ensuring the stability of pushing the pallet, while avoiding deviation and contact with the roller 11, which could cause damage to the components.

[0020] like Figure 2-3As shown, the support rod 12 has a fixed seat 121 at its bottom, and a drive motor 14 is mounted on the fixed seat 121. The output shaft of the drive motor 14 has a transmission gear 141. The drive motor 14 is fixed to the support rod 12 through the fixed seat 121. When the drive motor 14 starts, it drives the transmission gear 141 to rotate. The connecting block 221 has a rack 23 arranged along the length direction of the roller 11. The teeth of the rack 23 mesh with the transmission gear 141. The side wall of the rack 23 has a connecting piece 24 that connects to the bottom of the connecting block 221. When the drive motor 14 drives the transmission gear 141 to rotate, the transmission gear 141 can drive the rack 23 to move. The movement of the rack 23 can drive the second guide plate 22 to move back and forth toward the first guide plate through the connecting piece 24 and the connecting block 221, thereby realizing the action of pushing the pallet or separating it from the pallet.

[0021] like Figure 3-4 As shown, the rack 23 can move elastically relative to the connecting member 24 along the axial direction of the roller 11. When the second guide plate 22 pushes the tray to abut against the first guide plate 21, if the drive motor 14 continues to work, the second guide plate 22 will continue to push the tray but cannot move further. This would pose an overload risk to the drive motor 14, which could easily damage the drive motor 14 or cause the transmission gear 141 to wear down the rack 23. The rack 23 is designed to move elastically relative to the connecting member 24 along the axial direction of the roller 11, so that when the drive motor 14 continues to work, the rack 23 can continue to move a short distance, avoiding overload of the drive motor 14. At the same time, the second guide plate 22 remains in contact with the tray, increasing the reaction time when the second guide plate 22 moves into place, so as to drive the drive motor 14 again to drive in the opposite direction. This avoids the drive motor 14 from continuing to drive when the second guide plate 22 cannot move, which could lead to jamming or overload, thus playing a buffering role. The side wall of the connecting member 24 is provided with a strip-shaped limiting groove 241 arranged along the length direction of the roller 11, and the side wall of the rack 23 is provided with a strip-shaped limiting groove 241. The connector 24 is provided with a limiting slider 231 that mates with the strip-shaped limiting groove 241. The limiting slider 231 has a protrusion 232 on its side wall that protrudes beyond the outer side of the strip-shaped limiting groove 241. The limiting slider 231 passes through the strip-shaped limiting groove 241, allowing the connector 24 to slide relative to the rack 23. The protrusion 232 also fixes the rack 23, allowing the rack 23 to move stably on the connector 24. One end of the limiting slider 231 is provided with a telescopic spring 233 that is aligned with the strip-shaped limiting groove 241. The side wall of the connector 24 is provided with a fixing block 242 connected to the end of the telescopic spring 233. The two ends of the telescopic spring 233 are respectively connected to the limiting slider 231 and the fixing block 242, so that after the limiting slider 231 moves, the limiting slider 231 can drive the connector 24 and the second guide plate 22 to reset through the telescopic spring 233, so as to continuously realize the buffer function and increase the interaction force between the connector 24 and the rack 23, ensuring that the rack 23 can drive the second guide plate 22 to move normally when it moves normally.

[0022] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
