Description

Technical Field

[0001] This utility model relates to the field of pallet alignment technology, and in particular to a pallet alignment mechanism for a conveyor line. Background Technology

[0002] In a conveyor system, a pallet alignment mechanism is a mechanical device used to automatically correct the positional deviation of pallets during transport and precisely adjust them to the center of the conveyor line. Its core function is to solve the problem of pallets "deviating" due to conveyor vibration, manual loading deviation, and equipment docking errors, providing a stable and uniform positioning benchmark for subsequent automated operations such as robot gripping, barcode scanning, sorting, assembly, and stacking.

[0003] During transport, pallets may deviate from the centerline or even become stuck on the conveyor line. This necessitates manual correction at critical points, preventing smooth entry into the next process or equipment. This leads to frequent machine downtime for pallet repositioning, reducing production efficiency and increasing maintenance costs. Even after pallet alignment, if a pushing mechanism is lacking to advance it to the next process or equipment, operators must manually push the aligned pallet downstream. However, the alignment conveyor section may still be running slowly, causing the pallet to shift again after alignment. This prolongs material handling time, impacts overall production progress, reduces the automation level of the production line, and increases labor costs. Utility Model Content

[0004] The main purpose of this utility model is to provide a pallet centering mechanism for conveyor lines, which can effectively solve the problems of frequent equipment shutdowns to adjust pallet positions, reduced production efficiency, increased maintenance costs, extended material handling time, impact on overall production progress, reduced automation level of production lines, and increased labor costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pallet centering mechanism for a conveyor line, comprising a conveyor belt, a first support frame fixedly connected to the top of each conveyor belt, a top box fixedly connected to the top of four first support frames, a first support plate fixedly connected to the inner bottom wall of the top box, a placement tray disposed inside the first support plate, fixing blocks fixedly connected to the left and right sides of the placement tray, the other sides of two fixing blocks fixedly connected to the inner left and right sides of the first support plate, a guide rail groove formed between the first support plate and the placement tray, a motor disposed inside the top box, the bottom of the motor fixedly connected to the top wall of the placement tray, a rotating rod fixedly connected to the output end of the motor, a connecting plate fixedly connected to the outer side of the bottom end of the rotating rod penetrating the interior of the placement tray, and connecting rods penetrating the front and rear sides of the interior of the connecting plate.

[0006] Furthermore, the outer top ends of both connecting rods are located inside the guide rail groove, and a fixing ring is fixedly connected to the top end of both connecting rods. The bottom walls of both fixing rings are located at the top of the guide rail groove. A first support rod is rotatably connected to the outer bottom end of both connecting rods. A first hinge frame is rotatably connected to the other side of each of the four first support rods. A second support plate is fixedly connected to the inner side wall of each of the four first support frames.

[0007] Furthermore, each of the four first hinge frames is fixedly connected to a slide rod on its outer side wall, and the second support plate has a slide groove inside. The top outer sides of the two slide rods are slidably connected to the inside of the slide groove, and the bottom of each of the two slide rods is fixedly connected to a first push plate. The two first push plates are arranged on the front and rear sides of the top of the conveyor belt.

[0008] Furthermore, a control panel is fixedly connected to the front wall of the first support frame on the right front side, a fixing frame is fixedly connected to the left side wall of the two first support frames on the left side, a detector is fixedly connected to the bottom of the fixing frame, a transfer table is fixedly connected to the right side wall of the conveyor belt, and a second support frame is fixedly connected to the bottom of each transfer table.

[0009] Furthermore, a first device box is fixedly connected to the front side of the bottom wall of the transfer table, and a second device box is fixedly connected to the front side wall of the transfer table. Hydraulic rods are provided on both the left and right sides inside the first device box, and a second hinge frame is fixedly connected to the front end of the telescopic ends of the two hydraulic rods.

[0010] Furthermore, connecting frames are fixedly connected to the left and right sides of the interior of the two second device boxes, and second support rods are rotatably connected to the interior of the two second hinge frames. The outer sides of the two second support rods are rotatably connected to the interior of the two connecting frames, and I-shaped blocks are rotatably connected to the top outer sides of the two second support rods.

[0011] Furthermore, a connecting block is rotatably connected to the rear interior of both I-shaped blocks, and a second push plate is fixedly connected to the rear side wall of the two connecting blocks. The second push plate is located on the top front side of the transfer table.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model, through its first support frame, first support plate, motor, connecting rod, first support rod, sliding rod, sliding groove, and first push plate, solves the problem of frequent equipment shutdowns for pallet position adjustments, reduced production efficiency, and increased maintenance costs. The first support rod is rotatably connected to the outer top of each of the two connecting rods, and the other end of the first support rod is rotatably connected to the first hinge frame. The first support rod acts as an intermediate transmission component, converting the linear motion of the connecting rod into the swinging and translating motion of the first hinge frame. Since the outer wall of the first hinge frame is fixedly connected to the sliding rod, and the outer top of the sliding rod is nested within the sliding groove of the second support plate, the movement of the first hinge frame drives the sliding rod to slide linearly along the sliding groove in the front-to-back direction. This effectively reduces the time required for frequent adjustments due to inaccurate pallet position, improves equipment operating efficiency, extends equipment life, and ensures that materials remain intact during transport, meeting quality requirements.

[0013] 2. By using a transfer table, a second device box, a hydraulic rod, a connecting frame, a second support rod, an I-shaped block, and a second push plate, the problems of prolonged material handling time, impact on overall production progress, reduced automation level of the production line, and increased labor costs can be solved. The I-shaped block is rotatably connected to the connecting block via a pin on its rear side. This rotating structure can compensate for the slight angular deviation caused by the swing of the second support rod during transmission, ensuring that the thrust direction is always horizontal and backward along the surface of the transfer table. The rear side of the connecting block is vertically fixed to the second push plate. Therefore, the backward translation of the I-shaped block directly drives the second push plate to move backward synchronously, thereby effectively reducing manual intervention, reducing labor intensity, improving material handling efficiency, reducing material dwell time, and preventing material damage due to prolonged dwell time.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figure 1 - Figure 6As shown: A pallet centering mechanism for a conveyor line includes a conveyor belt 1, with a first support frame 2 fixedly connected to the top of each of the four first support frames 2, and a top box 3 fixedly connected to the top of each of the four first support frames 2. The pallet is conveyed from the left to the right by the conveyor belt 1, and the top box 3 at the top of the conveyor belt 1 and the bottom are supported by the first support frames 2 at the top of the conveyor belt 1. A first support plate 4 is fixedly connected to the inner bottom wall of the top box 3. A placement tray 5 is provided inside the first support plate 4. Fixing blocks 6 are fixedly connected to both the left and right sides of the placement tray 5. The other side of the two fixing blocks 6 is fixedly connected to the left and right sides inside the first support plate 4. A guide rail groove is opened between the first support plate 4 and the placement tray 5. The first support plate 4 inside the top box 3 is connected to the placement tray 5 through the fixing blocks 6 on both sides. The guide rail groove between the placement tray 5 and the first support plate 4 provides motion guidance for the transmission components. The two fixing blocks 6 fix the placement tray 5 inside the first support plate 4 on the one hand, and limit the sliding connecting rod 10 inside the guide rail groove on the other hand, to prevent excessive sliding and damage to the first push plate 17 at the bottom.

[0019] A motor 7 is installed inside the top box 3. The bottom of the motor 7 is fixedly connected to the top wall of the placement tray 5. By fixing the motor 7 to the top of the placement tray 5 and inside the top box 3, the motor 7 is externally protected. A rotating rod 8 is fixedly connected to the output end of the motor 7. The bottom outer end of the rotating rod 8 passes through the inside of the placement tray 5 and is fixedly connected to a connecting plate 9. Connecting rods 10 are connected through the front and rear sides of the inside of the connecting plate 9. When the motor 7, which is fixed to the top wall of the placement tray 5, is started, the output end of the motor 7 drives the rotating rod 8 to rotate around its own axis. Since the bottom outer end of the rotating rod 8 passes through the placement tray 5 and is fixedly connected to the connecting plate 9, the rotational motion of the rotating rod 8 is directly converted into the synchronous rotational motion of the connecting plate 9. The connecting rods 10 connected through the front and rear sides of the inside of the connecting plate 9 move synchronously with the rotation of the connecting plate 9.

[0020] like Figure 1 - Figure 6 As shown, the outer sides of the top ends of the two connecting rods 10 are both set inside the guide rail groove. The top ends of the two connecting rods 10 are fixedly connected to the fixing rings 11. The bottom walls of the two fixing rings 11 are both set at the top of the guide rail groove. Because the top ends of the connecting rods 10 are restricted by the guide rail groove between the first support plate 4 and the placement plate 5, they cannot follow the connecting plate 9 to make a complete circular motion. They can only slide horizontally towards each other along the extension direction of the guide rail groove. The bottom walls of the fixing rings 11 fixed at the top ends of the connecting rods 10 are attached to the top of the guide rail groove, which can effectively prevent the connecting rods 10 from deviating or shaking when sliding, and ensure that the connecting rods 10 always move stably along the guide rail groove.

[0021] Two connecting rods 10 are rotatably connected to the outer bottom ends of the first support rods 12. The other side of each of the four first support rods 12 is rotatably connected to a first hinge frame 13. The inner side walls of the four first support frames 2 are fixedly connected to a second support plate 15. The outer side walls of each of the four first hinge frames 13 are fixedly connected to a sliding rod 14. The second support plate 15 has a groove 16 inside. The top outer side of the two sliding rods 14 is slidably connected to the inside of the groove 16. The bottom of each of the two sliding rods 14 is fixedly connected to a first push plate 17. The two first push plates 17 are set on the front and rear sides of the top of the conveyor belt 1. The first support rods 12, which are rotatably connected to the outer bottom end of the fixed ring 11, swing as the fixed ring 11 moves horizontally. The other end of the first support rod 12 is rotatably connected to the first hinge frame 13, and thus the swing drives the first hinge frame 13 to move horizontally synchronously. Since the outer wall of the first hinge frame 13 is fixedly connected to the slide rod 14, and the top outer side of the slide rod 14 is slidably nested in the groove 16 of the second support plate 15, and is fixed to the inner wall of the four first support frames 2 by the second support plate 15, providing support and guidance for the slide rod 14, the horizontal movement of the first hinge frame 13 is converted into the stable sliding of the slide rod 14 along the groove 16. The first push plate 17 fixed at the bottom of the slide rod 14 moves towards the center along the front and rear sides of the top of the conveyor belt 1 synchronously with the slide rod 14; since the connecting rods 10, fixing rings 11, first support rods 12 and other components on the front and rear sides are symmetrically distributed, the moving speed and distance of the first push plates 17 on both sides are completely consistent.

[0022] In addition, as the first push plates 17 on both sides move towards the center, they simultaneously contact and push the pallet on the conveyor belt, gradually adjusting the pallet's position until the center of the pallet is aligned with the center of the conveyor belt 1, completing the centering operation. After centering is completed, the motor 7 reverses, driving the various components to move in the opposite direction through the transmission components such as the rotating rod 8, connecting plate 9, and connecting rod 10. The slide rod 14 retracts along the slide groove 16, and the first push plates 17 return to their initial open state, waiting for the next pallet to enter, thus realizing a continuous cycle of centering operation.

[0023] like Figure 1 - Figure 8 As shown, a control panel 18 is fixedly connected to the front wall of the first support frame 2 on the right side, through which the entire equipment is controlled. A fixing frame 19 is fixedly connected to the left side wall of the two first support frames 2 on the left side, and a detector 20 is fixedly connected to the bottom of the fixing frame 19. By fixing the detector 20 to the left side wall of the two first support frames 2 on the left side, the position of the pallet is detected when the conveyor belt 1 moves the pallet to the right and before it enters the centering device. The detector 20 captures the pallet signal and transmits it to the control panel 18. The control panel 18 determines that the pallet has reached the centering position according to a preset program, and then sends a start command to the motor 7 fixed to the top wall of the placement tray 5, triggering the centering action.

[0024] A transfer table 21 is fixedly connected to the right side wall of the conveyor belt 1. A second support frame 22 is fixedly connected to the bottom of the transfer table 21. The transfer table 21 is used to push the centered pallet to the next area, and the second support frame 22 at the bottom provides bottom support for the transfer table 21 at the top.

[0025] like Figure 1 - Figure 10 As shown, a first device box 23 is fixedly connected to the front side of the bottom wall of the transfer table 21, and a second device box 24 is fixedly connected to the front side wall of the transfer table 21. The first device box 23 and the second device box 24 provide external protection for the devices inside each of them. Hydraulic rods 25 are provided on both the left and right sides inside the first device box 23. The front ends of the telescopic ends of the two hydraulic rods 25 are fixedly connected to second hinge frames 26. Connecting frames 27 are fixedly connected to both the left and right sides inside the two second device boxes 24. The interiors of the two second hinge frames 26 are rotatably connected to second support rods 28. The outer sides of the two second support rods 28 are rotatably connected to the interiors of the two connecting frames 27. When the tray is fully inserted into the transfer table 21, the hydraulic rods 25 are activated, and the second hinge frames 26 fixed to the front ends of the telescopic ends of the hydraulic rods 25 move forward synchronously with the extension of the hydraulic rods 25. Because the second support rod 28, which is rotatably connected inside the second hinge frame 26, is rotatably nested inside the connecting frame 27 fixed on the left and right sides inside the second device box 24, and the connecting frame 27 provides a fulcrum for the second support rod 28, the forward movement of the second hinge frame 26 pushes the second support rod 28 to rotate around the connecting frame 27 as the axis, and the top of the second support rod 28 swings backward.

[0026] Two I-shaped blocks 29 are rotatably connected to the top outer sides of the two second support rods 28. Connecting blocks 30 are rotatably connected to the rear inner sides of the two I-shaped blocks 29. Second push plates 31 are fixedly connected to the rear side walls of the two connecting blocks 30. The second push plates 31 are located on the top front side of the transfer table 21 and move backward as the second support rods 28 swing, connected to the I-shaped blocks 29 on the top outer sides. The connecting blocks 30, rotatably connected to the rear inner sides of the I-shaped blocks 29, move backward synchronously, thereby causing the second push plates 31, fixed to the rear side walls of the connecting blocks 30, to slide backward along the top of the transfer table 21. During the sliding process, the second push plate 31 contacts the front side of the pallet and pushes the pallet to move backward along the top of the transfer table 21 until the pallet is pushed to the next process station behind the transfer table 21. After the pallet is transferred, the control panel 18 sends a retraction command to the hydraulic rod 25. The extension end of the hydraulic rod 25 retracts and pulls the second support rod 28 to rotate in the opposite direction through the second hinge frame 26. The I-shaped block 29 and the connecting block 30 drive the second push plate 31 to retract to the initial position.

[0027] It should be noted that this utility model is a pallet centering mechanism for a conveyor line. First, the motor 7, control panel 18, and hydraulic rod 25 are connected to an external power source to supply power to the device.

[0028] After receiving the signal, the control panel 18 immediately controls the motor 7 to start. The motor 7 is fixed to the top wall of the placement plate 5, and its output end drives the rotating rod 8 to rotate around its own axis. The bottom end of the rotating rod 8 passes through the placement plate 5 and is fixedly connected to the connecting plate 9. Therefore, the connecting plate 9 rotates synchronously with the rotating rod 8. The connecting rod 10, which passes through the front and rear sides inside the connecting plate 9, has its top outer side nested in the guide rail groove between the first support plate 4 and the placement plate 5. The top end is limited by the fixing ring 11. The bottom wall of the fixing ring 11 fits against the top of the guide rail groove to prevent the connecting rod 10 from shifting up and down.

[0029] When the connecting plate 9 rotates, the connecting rod 10 is constrained by the guide rail groove and cannot make a complete circular motion with the connecting plate 9. It can only slide synchronously in the opposite direction along the transverse trajectory of the guide rail groove. The top outer sides of the two connecting rods 10 are rotatably connected to the first support rod 12. The other end of the first support rod 12 is rotatably connected to the first hinge frame 13. The first support rod 12 acts as an intermediate transmission component, converting the linear motion of the connecting rod 10 into the swing and translation of the first hinge frame 13. Since the outer wall of the first hinge frame 13 is fixedly connected to the slide rod 14, and the top outer side of the slide rod 14 is nested in the slide groove 16 of the second support plate 15, the movement of the first hinge frame 13 drives the slide rod 14 to slide linearly in the front and back direction along the slide groove 16.

[0030] The bottom of the slide bar 14 is fixedly connected to the first push plate 17, and the first push plate 17 is located on the front and rear sides of the top of the conveyor belt 1. Therefore, the sliding of the slide bar 14 directly drives the first push plate 17 to complete the centering action. The two first push plates 17 move towards the center synchronously, applying symmetrical pushing force from the front and rear sides of the pallet to correct the front and rear offset of the pallet.

[0031] When the aligned pallet moves to the right along conveyor belt 1 and fully enters the pushing starting area of ​​transfer table 21, hydraulic rod 25 is activated. The front end of the telescopic end of hydraulic rod 25 is fixedly connected to the second articulated frame 26. The telescopic end of hydraulic rod 25 drives the second articulated frame 26 to move forward in a straight line along the inside of the first device box 23. Since the flow rate of the left and right hydraulic rods 25 is controlled to be consistent through hydraulic synchronization valves, the two second articulated frames 26 move forward in complete synchronization.

[0032] The connecting frame 27 serves as a fixed fulcrum, fixed to the left and right sides inside the second device box 24. The middle part of the second support rod 28 is rotatably connected to the connecting frame 27 via a pin, allowing only the second support rod 28 to rotate and swing around this fulcrum. When the second hinge frame 26 moves forward, the lower end of the second support rod 28 is pushed forward, causing the entire support rod to swing counterclockwise around the connecting frame 27. At this time, the lower end of the second support rod 28 moves forward, while the upper end lifts backward and upward, completing the conversion from translational motion to swinging motion.

[0033] The upper end of the second support rod 28 is rotatably connected to the I-shaped block 29 via a pin. When the second support rod 28 swings counterclockwise, the swinging motion of its upper end pushes the I-shaped block 29 to move backward in a straight line through the pin. The rear side of the I-shaped block 29 is rotatably connected to the connecting block 30 via a pin. This rotating structure can compensate for the small angular deviation caused by the swinging of the second support rod during the transmission process, ensuring that the thrust direction is always horizontal and backward along the surface of the transfer table 21. The rear side of the connecting block 30 is fixed vertically to the second push plate 31, so the backward translation of the I-shaped block 29 directly drives the second push plate 31 to move backward synchronously.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
