Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a pallet conveying device. Background Art

[0002] PTC heaters are widely used in new energy vehicles, often in car air conditioners, battery temperature control, and refrigerators. These heaters generate heat by passing an electric current through the PTC material. By leveraging the PTC material's increasing resistance as temperature rises, they automatically control the temperature, offering advantages such as precise control, high safety, and energy conservation and environmental protection. The production and assembly of these heaters involves the supply and transportation of numerous parts, typically carried out on pallets, with stacks of profiles stacked one above the other. Pallets serve as the direct carrier for loading materials into processing equipment and are typically transported directly to the equipment's loading area. From there, the pallets are moved to a retrieving location, allowing the equipment to grasp or remove materials from the retrieving location. However, due to vibration or swaying of the equipment itself, pallets can easily shift or deflect when transported from the loading area to the retrieving location, hindering accurate material handling by the processing equipment.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0044] like Figure 1-3A pallet conveying device is shown, and the pallet conveying device includes a power mechanism 1, a conveying assembly, and two sets of guide mechanisms 3. The conveying assembly includes two sets of conveying mechanisms 2, which are arranged side by side. The power mechanism 1 is connected to the two sets of conveying mechanisms 2 to drive the two sets of conveying mechanisms 2 to work. The two sets of guide mechanisms 3 are respectively arranged in a one-to-one correspondence with the two sets of conveying mechanisms 2, and the guide mechanisms 3 are arranged on the outside of the corresponding conveying mechanisms 2, and the height of the guide mechanisms 3 is higher than the height of the corresponding conveying mechanisms 2. In this embodiment, the conveying assembly includes two sets of conveying mechanisms 2 arranged side by side, so that the pallet can be carried and conveyed from both sides of the pallet, thereby improving the stability of the conveying. In addition, the two sets of guide mechanisms 3 are respectively located on the outside of the corresponding conveying mechanisms 2, thereby guiding the pallet to move along a predetermined route. Therefore, the pallet conveying device in this embodiment can convey the pallet stably and accurately, and the pallet does not shift or deflect during conveyance, so that the pallet can be accurately moved to the predetermined position, which is convenient for the processing equipment to accurately pick up and grab the material.

[0045] Furthermore, if Figure 1 、 Figure 2 As shown, there is a gap between the two sets of conveyor mechanisms 2. The pallet conveyor device also includes two pallet lifting mechanisms 4, which are respectively disposed at either end of the gap. In the pallet conveyor device, a gap is provided between the two sets of conveyor mechanisms 2 to accommodate the pallet lifting mechanisms 4. The two pallet lifting mechanisms 4 are disposed at either end of the gap, thereby providing pallet support devices at both ends of the pallet conveyor device. One end can be used for directly placing and retrieving materials from processing equipment during support, while the other end can be used to receive pallets, which are then placed by the pallet lifting mechanisms 4 between the two sets of conveyor mechanisms 2, facilitating pallet transfer or placement.

[0046] Furthermore, if Figures 1 to 3 As shown, the pallet conveying device also includes two sensors 5, which are respectively arranged at both ends of the conveying mechanism 2 for sensing the pallet at the starting and ending positions, and the starting and ending positions are respectively located on the two pallet lifting mechanisms 4. When the pallet is moved onto the pallet lifting mechanism 4, the sensor 5 senses the pallet, thereby triggering the pallet lifting mechanism 4 at the corresponding position to perform an action. Specifically, the starting and ending positions are respectively the starting position and the ending position. After the pallet lifting mechanism 4 at the starting position receives the pallet, it is sensed by the sensor 5, the two sets of conveying mechanisms 2 stop conveying, and the pallet lifting mechanism 4 descends, thereby placing the pallet on the two conveying mechanisms 2. After that, the two sets of conveying mechanisms 2 start to convey the pallet until the other sensor 5 at the ending position senses the pallet. After the sensor 5 at the ending position senses the pallet, the two sets of conveying mechanisms 2 stop conveying, and the pallet lifting mechanism 4 at the ending position lifts the pallet to support the pallet for a longer time.

[0047] In some embodiments of the tray lifting mechanism 4, such as Figure 5 As shown, the pallet lifting mechanism 4 includes a mounting plate 41, a lifting element 42, a plurality of guide columns 43, a connecting piece 44 and a lifting plate 45. The mounting plate 41 is arranged below the lifting plate 45. The lifting element 42 is arranged on the mounting plate 41, and the lifting element 42 is connected to the lifting plate 45. The guide column 43 is slidably arranged on the mounting plate 41, and the upper end of the guide column 43 is connected to the lifting plate 45. The connecting piece 44 is located below the mounting plate 41, and the connecting piece 44 is connected to the lower end of each guide column 43. The lifting element 42 drives the lifting plate 45 to perform lifting and lowering movements, and the guide column 43 guides the lifting plate 45 to precisely lift and lower, thereby improving the lifting stability of the pallet lifting mechanism 4. Specifically, the lifting element 42 can be an electric push rod or a pneumatic push rod.

[0048] Furthermore, the pallet lifting mechanism 4 also includes a positioning pin 46 and a buffer pad 47. The buffer pad 47 and positioning pin 46 are disposed on the lifting plate 45. The buffer pad 47 on the lifting plate 45 increases the friction between the lifting plate 45 and the pallet, improving the stability of the pallet on the lifting plate 45 and buffering equipment vibration, thereby preventing or reducing pallet vibration and pallet displacement caused by vibration. Furthermore, the positioning pin 46 on the lifting plate 45 can accurately locate the pallet position, thereby limiting the pallet position and improving the pallet's positioning accuracy, effectively preventing or reducing pallet displacement, and improving the accuracy of material handling by the processing equipment.

[0049] In some embodiments of the transmission mechanism 2, such as Figure 3 、 Figure 4 As shown, the conveyor mechanism 2 includes a conveyor frame 21, a driving sprocket 22, a driven sprocket 23, and a conveyor chain 24. The driving sprocket 22 and the driven sprocket 23 are respectively arranged at both ends of the conveyor frame 21, and the conveyor chain 24 passes through the driving sprocket 22 and the driven sprocket 23. The power mechanism 1 is connected to the driving sprocket 22. The power mechanism 1 drives the driving sprocket 22 to rotate, and the driving sprocket 22 drives the conveyor chain 24 to operate. At the same time, the driven sprocket 23 also rotates accordingly, allowing the pallet to move on the conveyor chain 24.

[0050] In addition, if Figure 4As shown, the conveyor mechanism 2 also includes a wheel seat 25, an adjusting screw 26, and a screw seat 27. The wheel seat 25 has an elongated hole oriented in the conveying direction, within which a mounting screw for connecting to the conveyor frame 21 is located. The screw seat 27 is positioned on the conveyor frame 21, near the center of the wheel seat 25 relative to the wheel seat 25. The adjusting screw 26 abuts the wheel seat 25 to adjust the tension of the conveyor chain 24. Either the driving sprocket 22 or the driven sprocket 23 is mounted on the wheel seat 25, with the driven sprocket 23 preferably being mounted on the wheel seat 25. During installation, the mounting screws are initially tightened to initially install the wheel seat 25. Then, the adjusting screw 26 is rotated, which pushes the wheel seat 25 outward, increasing the distance between the driving sprocket 22 and the driven sprocket 23, thereby adjusting the tension of the conveyor chain 24. Finally, the mounting screws are tightened again to fully install the wheel seat 25.

[0051] Furthermore, if Figure 4 As shown, the conveyor mechanism 2 also includes a roller chain 28, which is a long structure used to carry chain rollers. The roller chain 28 is installed on the conveyor frame 21 and is located below the tight edge of the conveyor chain 24. The width of the upper portion of the roller chain 28 is less than the inner link plate spacing of the conveyor chain 24. The conveyor chain 24 is mounted on the roller chain 28, and the rollers on the conveyor chain 24 roll along the roller chain 28. The roller chain 28 not only supports the tight edge of the conveyor chain 24 by means of bearing rollers, so that the conveyor chain 24 can carry pallets, but also guides the conveyor chain 24 along its length, making the operation of the conveyor chain 24 more precise and stable.

[0052] In some embodiments of the guide mechanism 3, such as Figure 3 As shown, guide mechanism 3 includes support legs 31 and roller guide rail 32. Roller guide rail 32 comprises a guide rail body and several rollers. The guide rail body is mounted on support legs 31. A groove is defined on the side of the guide rail body that is closest to conveyor mechanism 2, or more precisely, on the side of the guide rail body that is closest to the pallet. The rollers are positioned within the groove. When a pallet moves on conveyor mechanism 2, it is likely to contact guide mechanism 3. The rollers on guide mechanism 3 come into rolling contact with the pallet, guiding the pallet's movement while reducing friction and resistance to pallet movement.

[0053] For the aforementioned power mechanism 1, specifically, Figure 3As shown, the power mechanism 1 includes a motor 11, a transmission chain assembly 12, and a transmission shaft 13. The motor 11 is connected to the transmission chain assembly 12, which is in turn connected to the transmission shaft 13. The transmission shaft 13 is located in the gap between the two transmission mechanisms 2, with both ends of the transmission shaft 13 connected to the two transmission mechanisms 2. Of course, the motor 11 can also be connected to the transmission shaft 13 through a gear reduction mechanism. The power mechanism 1 synchronously drives the two transmission mechanisms 2 via the transmission shaft 13, facilitating their synchronous operation while also reducing the number of power mechanisms 1.

[0054] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
