Technical Field

[0002] The utility model belongs to the field of machinery, and in particular relates to a positioning component for a molded tray. Background Art

[0003] As the most fundamental containerized equipment for containerized units and unitized logistics, pallets are closely intertwined with the development of the logistics industry. The logistics industry has experienced steady growth in recent years, and with the nationwide implementation of palletized transportation, the pallet industry has also flourished. Pallets, as the primary means of moving and handling goods, are primarily used to protect cargo, automate freight transportation, and improve cargo flow efficiency. In today's commodity trading system, weight is often used as the unit of measurement for transaction value, including weight measurement of the cargo itself, prevention of overweight transport vehicles, and real-time weight gain or loss during cargo use. Therefore, the ability to visualize cargo weights would significantly improve trade efficiency.

[0004] Molded pallets, or plant fiber molded flat industrial pallets, are typically made from wood shavings, plant straw, bamboo, and other materials. They are monolithic structures, with the panels and support legs molded in a single process. The pallet's upper surface is smooth and flat, suitable for transporting a wide variety of goods, while the lower surface features reinforcing ribs. The pallet's surface is evenly distributed across the board, and its nine legs allow for forklift access in all four directions. This makes it a flat, single-sided pallet with four-way access.

[0005] Since molded pallets are made from recyclable resources such as straw, tree branches, wood chips, bamboo chips, bamboo fertilizer, etc., the production process usually adopts hot pressing and other methods. The raw materials and processes are relatively environmentally friendly. Therefore, molded pallets are increasingly occupying the theme of the pallet market, and the research on molded pallets is becoming more and more intensive. How to better utilize environmentally friendly raw materials and how to improve the load-bearing and strength of pallets are both key research directions of molded pallets.

[0006] Compared with traditional plastic or wooden pallets, molded pallets have the advantages of environmentally friendly materials, streamlined manufacturing processes, low manufacturing costs, low environmental pollution during the manufacturing process, and fewer post-manufacturing processing procedures. As for the pallets themselves, molded pallets are compacted using shredded waste materials, and the density of the compacted material is high. Compared with plastic pallets, they have high compressive strength, good wear resistance, and a wider range of usage scenarios. Compared with traditional wooden pallets, molded pallets undoubtedly have great advantages in terms of material sourcing. The materials for molded pallets are usually processing waste such as sawdust or crop waste, such as straw. Compared with wooden pallets that require logging, molded pallets not only reduce costs, but also meet the requirements of energy conservation, environmental protection, and protection of non-renewable resources.

[0007] After the molded pallet is pressed and formed, there are many burrs on its outer edge surface, which needs to be ground to obtain the final molded pallet product. Currently, one way to grind the edge of the molded pallet is to do it manually. The molded pallet is large in size, and manual processing is very time-consuming and labor-intensive, inefficient, and costly. The dust pollution generated is harmful to the health of the operator. In addition, there are individual differences in the grinding effect, which is not conducive to the quality control of the molded pallet. Another way is to use an automatic grinding mechanism to grind it. The clamping mechanism maintains a certain height when moving the unground molded pallet into the grinding mechanism and when moving the ground molded pallet out of the grinding mechanism. Therefore, the molded pallet must be kept at a height that the clamping mechanism can accurately clamp. Therefore, it is urgent to find a positioning component for the molded pallet to improve the grinding efficiency of the automatic grinding mechanism. Utility Model Content

[0008] In response to the defects of the existing technology, the utility model provides a positioning component for a molded pallet, which includes a traction device and a positioning device. The molded pallet is placed in the traction device, and the positioning device is used to detect the height at which the molded pallet is placed. When the positioning device detects that the height of the molded pallet is too high, the traction device descends and drives the molded pallet to descend to an appropriate height. When the positioning device detects that the height of the molded pallet is too low, the traction device rises and drives the molded pallet to rise to an appropriate height.

[0009] A positioning component for a molded pallet includes a traction device and a positioning device, the traction device includes a base plate and a traction chain, the base plate is used to place a workpiece, and the traction chain is used to pull the base plate; the positioning device is used to detect the height at which the workpiece is placed, thereby controlling the traction device to drive the workpiece up or down; when the positioning device detects that the height of the workpiece is too high, the traction device drives the workpiece down to an appropriate height; when the positioning device detects that the height of the workpiece is too low, the traction device drives the workpiece up to an appropriate height.

[0010] In some embodiments, the automatic edging mechanism is provided with two positioning components, and the automatic edging mechanism is located between the two positioning components. The two positioning components include an input positioning component and an output positioning component. The input positioning component is used to place the un-edged workpiece, and the output positioning component is used to place the edged workpiece; the automatic edging mechanism is also provided with a first clamping component and a second clamping component. The first clamping component is used to transfer the un-edged workpiece from the position of the input positioning component to the automatic edging mechanism, and the second clamping component transfers the edged workpiece from the automatic edging mechanism to the position of the output positioning component.

[0011] In some embodiments, the workpiece is a molded pallet, and the input positioning component and the output positioning component both neatly stack multiple molded pallets. When a molded pallet on the input positioning component is removed, its height is bound to decrease. If the remaining molded pallets are not moved upward in time to maintain the original height, the first clamping assembly will not be able to smoothly grasp the molded pallet, affecting the overall progress. Therefore, the positioning device must promptly detect the stacking height of the molded pallets to be edged in the input positioning component and make timely adjustments so that the first clamping assembly can successfully grasp the molded pallet every time and place it in the automatic edge grinding mechanism. At the same time, when a molded pallet on the output positioning component is moved in, its height is bound to increase. If the molded pallet is not moved downward in time to maintain the original height, the second clamping assembly will collide with the molded pallet when it descends, causing damage to the second clamping assembly and even a serious safety accident. Therefore, the positioning device must promptly detect the stacking height of the edged molded trays in the output positioning component and make timely adjustments so that the second clamping assembly can successfully place the edged molded trays in the output positioning component every time. By adjusting the position of the molded trays, the positioning component ensures that the height of the molded trays to be edged, the height of the molded trays placed by the automatic edge grinding mechanism, and the height of the edged molded trays remain consistent.

[0012] Furthermore, the substrate is provided with a limiting block for limiting the placement position of the workpiece.

[0013] In some implementations, the substrate is larger than the mold tray. This can lead to misalignment when the mold tray is placed into the substrate input positioning component. This misalignment directly impacts subsequent automatic displacement and automatic edging. By placing a retaining block on the substrate, the mold tray is positioned against the retaining block when placed into the substrate. This allows for quick and precise positioning of the mold tray, effectively and simply resolving this issue.

[0014] Furthermore, the traction chains are arranged on both sides of the base plate, and the number of traction chains on each side of the base plate includes one or more.

[0015] In some embodiments, there are four traction chains, which are located on both sides of the substrate, two on each side, for smoothly traction of the substrate up and down.

[0016] Furthermore, the traction device further includes gears and lifting rods, the gears include a first gear and a second gear, and the lifting rods are arranged on both sides of the base plate.

[0017] Furthermore, the first gear is arranged at both ends of the lifting rod, and when the traction chain and the first gear chain drive the substrate to rise or fall, the lifting rod rises or falls along with the substrate.

[0018] In some embodiments, a lifting rod is used to support the traction chain.

[0019] Furthermore, the second gear is arranged at both ends of the transmission shaft, and the second gear is suspended above the base plate.

[0020] Furthermore, the traction device also includes a base bar, and the base bar and the second gear are provided with uniform serrations for engaging with the transmission control substrate to maintain horizontality.

[0021] The traction chain and first gear are located on either side of the base, pulling each side of the base. As the traction chain and first gear pull the base upward or downward, the second gear and base bar pull one end of the base upward or downward. If the traction chain and first gear pull upward or downward too quickly, or if the two traction chains move at different speeds, causing the base to tilt, the coordination between the second gear and base bar will loosen, causing the second gear to rotate faster, causing one end of the base to rise or fall faster, thus keeping the base level. The perfect coordination of the gears and traction chain keeps the base and the upper surface of the molded tray stacked above it aligned, allowing the entire base to rise or fall at a uniform speed.

[0022] In some embodiments, each rotation of the base bar and the second gear is equivalent to a height of about 1 cm, that is, equivalent to raising one side of the base plate by about 1 cm.

[0023] Furthermore, it also includes a frame, one end of the traction chain is fixed to the base plate, and the other end is fixed to the crossbeam of the frame.

[0024] In some embodiments, the frame provides support for the entire positioning component.

[0025] Furthermore, the positioning device and the base strip are fixed on the frame.

[0026] Furthermore, the workpiece includes a molded pallet. Since the molded pallet after pressing has burrs on its edges, it is necessary to perform automatic edge grinding on the edges of the molded pallet.

[0027] The utility model has the following beneficial effects:

[0028] (1) The utility model provides a positioning component for a molded pallet, wherein the positioning component includes a traction device and a positioning device. The molded pallet is placed in the traction device, and the positioning device is used to detect the height at which the molded pallet is placed. When the positioning device detects that the molded pallet is placed too high, the traction device descends and drives the molded pallet to descend to an appropriate height. When the positioning device detects that the molded pallet is placed too low, the traction device ascends and drives the molded pallet to ascend to an appropriate height.

[0029] (2) The base plate is kept horizontal by the meshing transmission control of the second gear and the base bar.

[0030] (3) The use of the utility model will improve the working efficiency of the automatic edge grinding mechanism in inputting un-edge-grinded molded pallets and outputting edge-grinded molded pallets. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments described below are intended to facilitate understanding of the present invention and do not have any limiting effect on the present invention.

[0038] Example 1: A positioning component for a molded tray

[0039] like Figures 1-2As shown, a positioning component for a molded pallet includes a traction device 1 and a positioning device 2. The positioning device 2 is used to detect the height of the workpiece, thereby controlling the traction device 1 to move the workpiece up or down. When the positioning device 2 detects that the workpiece is placed too high, the traction device 1 lowers the workpiece to the appropriate height. When the positioning device 2 detects that the workpiece is placed too low, the traction device 1 raises the workpiece to the appropriate height. The positioning device 2 is positioned near the upper end of a frame 8, which provides support for the entire positioning component. The traction device 1 includes a base plate 3, a traction chain 4, a gear 5, and a lifting rod 6. The base plate 3 is provided with a limiting block 7 to define the placement of the workpiece. The workpiece must engage the limiting block 4 when placed on the base plate 3. Two traction chains 4 are provided on each side of the base plate 3 to smoothly move the base plate 3 up and down. Each traction chain 4 is fixed to the base plate 3 at one end and to the crossbeam 12 of the frame 8 at the other end. Lifting rods 6 are provided on each side of the base plate, one on each side. Gear 5 includes a first gear 9 and a second gear 10. The first gear 9 is mounted at both ends of the lifting rod 6. When the traction chain 4 and the first gear 9 drive the base plate 3 upward or downward, the lifting rod 6 rises or falls with the base plate 3. The second gear 10 is mounted at both ends of the transmission shaft 23 and is suspended above the base plate 3. The traction device 1 also includes a base bar 11. The base bar 11 and the second gear 10 are uniformly serrated and mesh with each other to control the base plate 3 to maintain its horizontal position. When the traction chain 4 and the first gear 9 pull the base plate 3 upward or downward, the second gear 10 and the base bar 11 pull one end of the base plate upward or downward. If the traction chain 4 and the first gear 9 pull upward or downward too quickly, or if the two traction chains 4 move at different speeds, causing the base plate 3 to tilt, the second gear 10 and the base bar 11 will loosen their engagement, causing the second gear 10 to rotate faster, causing one end of the base plate 3 to rise or fall faster, thereby maintaining the base plate 3 at all times. Each rotation of the base bar 11 and the second gear 10 corresponds to a height increase of approximately 1 cm, which is equivalent to raising one side of the base plate by approximately 1 cm. Through the cooperation between the traction chain 4 and the first gear 8 and the cooperation between the second gear 10 and the base bar 11, the base plate 3 can be raised or lowered horizontally at a uniform speed.

[0040] Example 2: Operation of the positioning component

[0041] like Figure 3As shown, the automatic edging mechanism 13 is equipped with two positioning components, located between the two positioning components. The two positioning components include an input positioning component 14 and an output positioning component 15. The workpiece edged by the automatic edging mechanism 13 is a molded pallet 16. The input positioning component 14 is used to place un-edged molded pallets 16, and the output positioning component 15 is used to place edged molded pallets 16. The automatic edging mechanism 13 also has a first clamping assembly 17 and a second clamping assembly 18. The first clamping assembly 17 is used to transfer un-edged molded pallets 16 from a base plate 19 of the input positioning component 14 to the automatic edging mechanism 13, and the second clamping assembly 18 transfers edged molded pallets 16 from the automatic edging mechanism 13 to a base plate 20 of the output positioning component 15. The base plate 19 neatly stacks multiple un-edged molded pallets 16, and the base plate 20 neatly stacks multiple edged molded pallets 16.

[0042] When the unpolished molded tray 16 placed on the substrate 19 is clamped by the first clamping assembly 17 and placed in the automatic edging mechanism 13, its height is bound to decrease. The positioning device 21 of the input positioning component 14 detects the decrease in the height of the molded tray 16 and immediately controls the traction device of the input positioning component 14 to drive the substrate 19 to rise immediately. This ensures that the first clamping assembly 17 can still accurately clamp the unpolished molded tray 16 at the same height position next time. At the same time, the second clamping assembly 18 clamps the polished molded tray 16 from the automatic edging mechanism 13 and transfers it to the substrate 20. The height of the molded tray 16 on the substrate 20 increases. The positioning device 22 of the output positioning component 15 detects the increase in the height of the molded tray 16 and immediately controls the traction device of the output positioning component 15 to drive the substrate 20 to descend immediately. This ensures that the second clamping assembly 18 can still accurately place the polished molded tray 16 at the same height position next time.

[0043] During the operation of the automatic edging mechanism 13, the input positioning component 14 and the output positioning component 15 adjust the position of the molded tray 16 to ensure that the height of the molded tray 16 to be edged, the height of the molded tray 16 placed by the automatic edging mechanism 13, and the height of the molded tray 16 that has been edged are consistent. If the remaining molded trays 16 of the substrate 19 are not moved upward in time to maintain the original height, the first clamping assembly 17 will not be able to smoothly grasp the molded tray 16, affecting the overall progress; similarly, when the substrate 20 moves into a molded tray 16, if the height of the molded tray 16 is not lowered in time to maintain the original height, the second clamping assembly 18 will collide with the molded tray 16 when it descends, causing damage to the second clamping assembly 18 and even a serious safety accident.

[0044] Although the present invention is disclosed as above, it is not limited thereto. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope defined by the claims.
