Description

Technical Field

[0001] The present application relates to the technical field of freeze-drying transport equipment, and in particular to a pallet transport platform. Background Art

[0002] In the freeze-drying workshop, the materials to be processed need to go through pre-treatment, temporary storage in cold storage, freeze-drying, sorting and packaging before the final product can be obtained.

[0003] Materials need to be transferred between the equipment in each process, usually by laying them flat on pallets for transfer. Nowadays, workshops tend to be highly automated to reduce the risk of contamination caused by manual operations, so robots are usually used to grab and transfer pallets.

[0004] However, when the robot grabs the pallet, the pallet may not be placed accurately enough, which may cause the robot to grab it with difficulty, or even cause the pallet to fall from the conveyor belt, resulting in unnecessary losses. Utility Model Content

[0005] In order to improve the situation where robots have difficulty in grasping pallets when transferring them, which may even cause the pallets to fall from the conveyor belt, the present application provides a pallet transportation platform.

[0006] The present application provides a pallet transport platform, which adopts the following technical solutions:

[0007] A pallet transport platform, comprising:

[0008] A frame, wherein two parallel and spaced apart conveyor chains are arranged on the frame, and the conveying directions and conveying speeds of the two conveyor chains are consistent;

[0009] A plurality of groups of sprockets, wherein the plurality of groups of sprockets are spaced apart along the length direction of the conveyor chain, each group of sprockets comprises two coaxially fixed sprockets, and the two sprockets in the same group are respectively meshed with one conveyor chain;

[0010] Multiple groups of paddles, wherein two paddles form a group, and the paddles in different groups are spaced apart along the length direction of the conveyor chain. The two paddles in the same group are parallel and spaced apart, and their length directions are perpendicular to the length direction of the conveyor chain. Each paddle is connected to two conveyor chains at the same time, and the paddles move with the conveyor chains. When conveying a pallet, the opposite side walls of the two paddles in the same group are used to abut against the outer wall of the pallet.

[0011] By adopting the above technical solution, when conveying the pallet, the opposite side walls of the two shift plates in the same group will be used to support the outer wall of the pallet and clamp the pallet, ensuring that the pallet always remains in the correct position during the conveying process and can move stably with the conveyor chain to facilitate subsequent robot grasping operations. At the same time, it also effectively reduces the possibility of the pallet falling, thereby improving production efficiency and reducing costs and safety risks.

[0012] Optionally, the sprocket includes a driving sprocket and a driven sprocket, a driving member is provided on one side of the driving sprocket, and an output shaft of the driving member is coaxially fixed with the driving sprocket.

[0013] By adopting the above technical solution, the driving member can drive the driving sprocket to rotate, thereby driving the conveyor chain to run synchronously, and the setting of the driven sprocket ensures the tension of the conveyor chain, and also ensures the smooth operation of the conveyor chain.

[0014] Optionally, each of the shift plates includes a first extension plate and a second extension plate, the first extension plate is close to the conveyor chain and connected to the conveyor chain, and in the same group of shift plates, the second extension plate is arranged on the side where the two first extension plates are close to each other, and the second extension plate is perpendicular to the first extension plate.

[0015] By adopting the above technical solution, the second extension plate perpendicular to the first extension plate increases the contact area with the pallet, and can effectively clamp the pallet.

[0016] Optionally, both ends of the first extension plate along its length direction are provided with connecting pieces, and the two connecting pieces of the same first extension plate are respectively fixedly connected to a conveying chain.

[0017] By adopting the above technical solution, the shift plate can be stably connected to the conveyor chain through the connecting piece, further improving the connection strength between the shift plate and the conveyor chain, ensuring that the shift plate will not fall off or shift during high-speed transportation.

[0018] Optionally, in the same set of dial plates, two of the second extension plates are provided with anti-slip layers on opposite side walls.

[0019] By adopting the above technical solution, the anti-skid layer enhances the friction between the paddle and the pallet, effectively preventing the pallet from sliding or shifting during transportation, and further improving the positioning accuracy.

[0020] Optionally, in the same set of shifting plates, two of the second extension plates are embedded with a plurality of balls on opposite side walls, a portion of the balls are located outside the second extension plates, and each of the balls is rollingly connected to the second extension plates.

[0021] By adopting the above technical solution, the rolling ball contacts the pallet. When the pallet is about to leave the paddle, the ball can roll by itself, reducing the friction between the pallet and the paddle, thereby reducing the wear of the pallet and the resistance of the pallet during movement.

[0022] Optionally, a slide groove is provided on the surface of the first extension plate close to the second extension plate, and a slider is provided at the bottom of the second extension plate. The slider is engaged in the slide groove and is slidably connected to the slide groove. The length direction of the slide groove is consistent with the length direction of the conveying chain. The two second extension plates of the same group of the shift plates can slide towards or away from each other.

[0023] By adopting the above technical solution, the second extension plate that can slide relative to the first extension plate improves the use flexibility of the shifting plate, so that it can adapt to pallets of different sizes.

[0024] Optionally, an elastic member is provided in the slide groove, one end of the elastic member is connected to the sliding block, and the other end of the elastic member is connected to the inner side wall of the first extension plate at the slide groove.

[0025] By adopting the above technical solution, the elastic member provides a buffering capacity for the paddle plate, which can absorb the impact and reduce damage when the pallet contacts the paddle plate. At the same time, it also enables the paddle plate to fit the pallet more closely, thereby improving the accuracy of position fixation.

[0026] In summary, the present application includes at least one of the following beneficial effects:

[0027] 1. By using the paddle to clamp and position the pallet, the accuracy of the pallet position is ensured, making it easier and more accurate for the robot to grab the pallet, while also preventing the pallet from falling during transportation;

[0028] 2. The ball bearings are set to reduce the friction between the pallet and the paddle, so that the pallet can smoothly break away from the paddle during the grabbing process, thus improving the material transfer efficiency;

[0029] 3. By adopting the second extension plate to be slidably connected to the first extension plate, and arranging an elastic member in the slide groove, after the second extension plate abuts against the pallet, it can have a certain buffering effect under the action of elastic force, so that the shift plate can be suitable for pallets of various sizes, with a wide range of applications.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] Embodiment 1:

[0038] Embodiment 1 of the present application discloses a pallet transport platform, referring to Figure 1 and Figure 2 The pallet transport platform includes a frame 1, on which two parallel conveyor chains 2 are mounted. The two conveyor chains 2 are not only parallel to each other but also maintain a certain interval, and the conveying directions and speeds of the two conveyor chains 2 are consistent. This arrangement ensures the stability and continuity of the pallet 3 during transportation.

[0039] A plurality of sprockets 4 are arranged on the frame 1, and the plurality of sprockets 4 are spaced apart along the length direction of the conveyor chain 2, and the spacing between the sprockets 4 can be set according to the frequency of grabbing the pallet 3. Each sprocket 4 includes two coaxially fixed sprockets 4, and each group of two coaxial sprockets 4 is respectively engaged with one conveyor chain 2, so that when the sprockets 4 rotate, the conveyor chain 2 can be driven to run synchronously and at a uniform speed, ensuring that the pallet 3 will not deviate or fall due to speed changes or asynchronism during transportation.

[0040] Furthermore, different groups of sprockets 4 also include a driving sprocket 41 and a driven sprocket 42, wherein the frame 1 is equipped with a driving member on one side corresponding to the driving sprocket 41, and the driving member may be a servo motor, and the output shaft of the driving member is coaxially fixed with one of the driving sprockets 41 in the same group, so as to drive the driving sprocket 41 to rotate, and then drive the conveyor chain 2 to run synchronously. The setting of the driven sprocket 42 ensures the tension of the conveyor chain 2 and ensures the smooth operation of the conveyor chain 2.

[0041] Reference Figure 1 and Figure 2Furthermore, the conveyor chain 2 is provided with a plurality of groups of paddles 5 spaced apart along the length direction of the conveyor chain 2, each group of paddles 5 includes two parallel paddles 5, and a certain interval is maintained between the two paddles 5 in the same group, and their length directions are perpendicular to the length direction of the conveyor chain 2. Each paddle 5 is connected to two conveyor chains 2 at the same time, and when the conveyor chain 2 moves, the paddle 5 will also move accordingly.

[0042] Specifically, each of the paddle plates 5 includes a first extension plate 51 and a second extension plate 52, wherein the first extension plate 51 is in close contact with the conveyor chain 2, and each of the first extension plates 51 is integrally formed with connecting pieces 511 at both ends in the length direction thereof, and the two connecting pieces 511 on the same first extension plate 51 are respectively fixedly connected to a conveyor chain 2, thereby ensuring that the paddle plate 5 will not fall off or shift during transportation. The second extension plate 52 is fixed to the side where the two first extension plates 51 of the same group are close to each other, and is perpendicular to the first extension plate 51. The second extension plate 52 perpendicular to the first extension plate 51 increases the contact area with the pallet 3, thereby improving the effectiveness of the clamping operation.

[0043] During the conveying process of pallet 3, when pallet 3 is transferred from one transport platform to another, a second extension plate 52 of the same group first abuts against one side of pallet 3. As the conveyor chain 2 runs, another second extension plate 52 of the same group rises from below and completely clamps pallet 3 between the two second extension plates 52 of the same group, thereby clamping pallet 3 and ensuring that pallet 3 can always remain in the correct position during transportation, which is convenient for subsequent robot grasping operations and can effectively reduce the possibility of pallet 3 falling.

[0044] The implementation principle of a pallet transport platform in Example 1 of the present application is as follows: a plurality of groups of spaced-apart shift plates 5 are arranged on the conveyor chain 2, and two shift plates 5 in the same group clamp the same pallet 3 during operation, thereby improving the operational stability of the pallet 3 and enabling the pallet 3 to always remain in the correct position during transportation, which is convenient for subsequent robot grasping operations.

[0045] Embodiment 2:

[0046] The difference between Example 2 and Example 1 is that: Figure 3 In the same group of shift plates 5, the two second extension plates 52 are fixed with anti-skid layers 521 on the opposite side walls. The anti-skid layers 521 can be made of materials with greater viscosity such as rubber, or made of materials with greater surface roughness. When clamping the pallet 3, the anti-skid layer 521 directly contacts the outer wall of the pallet 3. The anti-skid layer 521 can increase the friction between the pallet 3 and further prevent the pallet 3 from sliding or deflecting during transportation, and also further improve the position accuracy of the pallet 3.

[0047] Embodiment 3:

[0048] The difference between Example 3 and Example 2 is that: Figure 4 , a plurality of balls 522 are embedded on the opposite side walls of the two second extension plates 52 in the same set of paddles 5, and a part of the balls 522 is located outside the second extension plates 52, and is kept in a rolling connection with the second extension plates 52. When clamping, the balls 522 directly contact the outer wall of the tray 3; and when the tray 3 needs to be separated from the paddle 5, the balls 522 can roll by themselves, thereby reducing the friction resistance between the tray 3 and the paddle 5, making the separation process of the tray 3 smoother and more efficient. This design can not only protect the tray 3 from wear, but also reduce the resistance during the movement of the tray 3, further improving the efficiency of material transfer.

[0049] Embodiment 4:

[0050] The difference between Example 4 and Example 1 is that: Figure 5 In order to adapt to pallets 3 of different sizes, a slide groove 512 is provided on the surface of the first extension plate 51 close to the second extension plate 52, and a slider 523 matching the slide groove 512 is fixed at the bottom of the second extension plate 52. The slider 523 can be clamped in the slide groove 512 and slide along the slide groove 512. The opening direction of the slide groove 512 is consistent with the length direction of the conveyor chain 2, so the two second extension plates 52 in the same group of the shifting plate 5 can be slid and adjusted in the direction of approaching or moving away from each other as needed. Such a design gives the shifting plate 5 higher flexibility in use, so that it can be adjusted accordingly according to the actual size of different pallets 3.

[0051] At the same time, an elastic member 6 is also installed inside the slide groove 512. The elastic member 6 can be a compression spring. One end of the elastic member 6 is fixed to the slider 523, and the other end is fixed to the wall surface of the first extension plate 51 located inside the slide groove 512. The existence of the elastic member 6 provides a buffering capacity for the paddle plate 5. When the tray 3 comes into contact with the paddle plate 5, the elastic member 6 can absorb part of the impact energy, thereby reducing potential damage to the tray 3 and the paddle plate 5. At the same time, the elastic member 6 can also push the second extension plate 52 to fit more closely to the outer wall of the tray 3, thereby improving the accuracy of position fixation. The two second extension plates 52 in the same group are also fixed with ribs 524 on the side walls away from each other. The bottom of the ribs 524 is also fixed to the slider 523, which can provide a stable support force for the movement of the second extension plates 52.

[0052] When the size of the tray 3 changes, for example, it becomes larger, when the lever plate 5 clamps the tray 3, the two second extension plates 52 in the same group will be pushed by the tray 3, so that the two second extension plates 52 will move away from each other, so as to better adapt to the tray 3 with the increased size, and when the second extension plate 52 moves, the slider 523 will compress the elastic member 6, so that the elastic member 6 stores elastic potential energy, so the elastic member 6 will push the second extension plate 52 to clamp the tray 3, further increasing the clamping force.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
