Description

Technical Field

[0001] This utility model belongs to the field of conveying mechanism technology, specifically a flexible clamp ring transfer mechanism. Background Technology

[0002] Traditional rigid conveyor lines (such as chains and double-speed chains) require fixtures to achieve synchronous movement through mechanical engagement with the drive chain links. Therefore, these fixtures need to integrate complex structures such as guide rails and locking mechanisms, resulting in high maintenance costs, heavy weight, and a high degree of customization. Furthermore, the spacing of these fixtures is usually fixed, limiting their potential for modification and making them difficult to integrate with products of different specifications.

[0003] Of course, there are methods on the market that use belts to transport the carrier, such as the publicly available technical document "CN 222203812 U, Lifting and Circulating Conveying Mechanism". However, continuous circulating operation cannot be achieved. Lifting devices need to be set at both ends of the conveying mechanism for jig transfer. The structure is also relatively complex, and the equipment is large and has high manufacturing costs. Utility Model Content

[0004] The purpose of this invention is to provide a flexible clamp ring transfer mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Rollers are installed at both ends of the main body, and the two rollers are wound around the conveyor belt. The upper and lower positions of the conveyor belt are respectively provided with a first support part located on the inner side and a second support part located on the outer side. The first support part and the second support part are used to support the clamp body and extend to the rollers at both ends. The rollers and the conveyor belt form a clamping position.

[0008] The clamp body is provided with a first contact part and a second contact part. It moves forward by friction with the transmission belt. The first contact part contacts the outer surface of the transmission belt, and the second contact part contacts the inner surface of the transmission belt. The position is switched by the clamping position.

[0009] In a further technical solution, the first support portion and the second support portion respectively form concave channels with the main body, and the second contact portion is arranged laterally inward and placed in the channels.

[0011] In a further technical solution, the outer periphery of the roller is provided with a soft rubber material, and the conveyor belt has two belts.

[0012] In a further technical solution, the length of the main body is less than the length of the first support portion and the second support portion, and an installation space is formed between the first support portion and the second support portion at both ends. Limiting components are installed in the two installation spaces to limit the position of the clamp.

[0013] In a further technical solution, the limiting component includes at least one first cylinder and at least one second cylinder respectively installed in two installation spaces, wherein the output ends of the first cylinder and the second cylinder can extend out of the first support portion and abut against the clamp body.

[0014] A further technical solution is that a limiting groove is provided on the first contact portion of the fixture body.

[0015] A further technical solution involves installing at least two third cylinders in at least one of the installation spaces, with the two third cylinders arranged symmetrically and their output ends extending out to abut against the second contact portion.

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Please refer to Figure 1-7 ;

[0031] This utility model aims to provide a more structurally simple flexible conveying mechanism, specifically including a main body 1 and a clamp body 2; rollers 31 are installed at both ends of the main body 1, and the two rollers 31 are wound around a conveyor belt 32; a drive device 6 is installed on one side of the main body 1, and the output end of the drive device 6 is connected to one of the rollers 31 for transmission, and achieves rolling circulation through the conveyor belt 32; a first support part 13 and a second support part 14 are located at the upper and lower positions of the main body 1, wherein the first support part 13 is located inside the upper conveyor belt 32, and the second support part 14 is located inside the upper conveyor belt 32. The support portion 14 is located on the outer side of the lower conveyor belt 32, and both ends of the first support portion 13 and the second support portion 14 extend laterally to a position close to the roller 31, minimizing the distance between the end and the roller 31 as much as possible to make the transition smoother. In addition, a clamping position is formed between the roller 31 and the conveyor belt 32. The clamp body 2 is provided with a first contact portion 21 and a second contact portion 22 on its inner side. The first contact portion 21 contacts the outer surface of the conveyor belt 32, and the second contact portion 22 contacts the inner surface of the conveyor belt 32. The position is switched by the clamping position.

[0032] The explanation is based on the initial state where the clamp is located on the upper surface. In this state, the first support part 13 supports the conveyor belt 32 and the clamp body 2 to prevent the conveyor belt 32 from bending. At the same time, the clamp body 2 applies pressure to the outer side of the conveyor belt 32 under the action of gravity, forming a state where the first contact part 21 and the first support part 13 clamp the conveyor belt, so that a large frictional force is generated between the first contact part 21 and the conveyor belt 32. At this time, the second contact part 22 is located below the first support part 13.

[0033] The drive device 6 drives one of the rollers 31 to rotate and drive the conveyor belt 32 to move forward. Under the action of friction, the clamp body 2 and the transmission belt will not move relative to each other. That is, the clamp body 2 will move forward synchronously with the transmission belt. When the clamp body 2 reaches the end of the first support part 13, the second contact will also reach the intersection of the conveyor belt 32 and the roller 31. However, the first contact part 21 is not completely separated from the outer side of the conveyor belt 32. Since there is a gap between the first support part 13 and the roller 31, it is necessary to continue to push the clamp body 2 forward with the help of friction.

[0034] When the second contact part 22 enters the clamping position formed between the transmission belt and the roller 31, since the second contact part 22 is clamped, it will not move relative to the roller 31 and the transmission belt 32, but will rotate synchronously with the roller 31. After rotating 180°, it reaches the end of the second support part 14. Under the action of gravity, the second contact part 22 applies pressure to the inside of the transmission belt 32, and cooperates with the second support part 14 to form a clamping state on the transmission belt. Thus, the switching of the upper and lower positions of the clamp is completed.

[0035] It should be noted that the second contact part 22 is divided into front and rear parts. Since there is a gap between the end of the second support part 14 and the roller 31, after the front part is released from the clamping of the roller 31 and the transmission belt, the rear part remains clamped, providing thrust for the clamp body 2 to continue to move forward.

[0036] The second support part 14 supports the conveyor belt 32 and the clamp body 2, preventing the conveyor belt from bending and ensuring the straight movement of the clamp body 2. Then, under the action of friction between the second contact part 22 and the inner side of the conveyor belt 32, the clamp body 2 is driven to move downward in the direction of another roller 31. Finally, based on the same principle, the clamp body 2 reaches the other end of the second support part 14 and rotates 180° with the other roller 31 to reach the upper position, realizing the switching between the lower and upper positions and completing the complete cycle of the clamp. In the past, most clamp cycles were achieved by using rigid connection. However, this utility model can also achieve clamp cycles in a flexible transmission mechanism by using the above-described embodiment, which greatly simplifies the structure and reduces the wear of parts.

[0037] Since the connection between the transmission belt and the clamp body 2 is not rigid, the position of the clamp body 2 or the spacing between multiple clamp bodies 2 can be adjusted at any time. That is, the transmission belt can keep running relative to the clamp body 2 when the limit component 4 stops the clamp body 2. After the adjustment is completed, the clamp bodies 2 can be released one by one. It has greater flexibility. Moreover, during the production process, sometimes the clamp moves due to foreign objects. If a rigid connection is used, it will cause the entire production line to stop running and easily burn out the driver.

[0038] This utility model uses a flexible method to drive the clamp body 2 to move, and innovatively sets a first contact part 21 and a second contact part 22 to realize the switching of the upper and lower positions, realizing the clamp circulation in the flexible transmission mechanism. There is no need to set up a lifting device to assist, breaking the way that only a rigid transmission mechanism can realize the clamp circulation. Moreover, the structure is simpler, and the clamp can be adjusted in both the upper and lower positions, making it more flexible. Due to the simpler structure, the production and maintenance costs are lower.

[0039] In this embodiment of the utility model, the first support portion 13 and the second support portion 14 respectively form a concave channel 15 between themselves and the main body 1, and the second contact portion 22 is arranged laterally inward in the channel 15 to form a limit and prevent the clamp from coming out.

[0040] One embodiment of the second contact part 22 of this utility model specifically includes two left and right distributed front fixing rods 221 and two left and right rear fixing rods 222 respectively. The front fixing rods 221 and rear fixing rods 222 are hollowed out and the distance is less than the diameter of the roller 31. First, the fixing rods on both sides can limit the clamp body 2. Second, the fixing rods are cylindrical and have a relatively small outer diameter, which can more easily enter between the transmission belt and the roller 31. Finally, the front and rear arrangement can lock the roller 31 to prevent relative slippage and make it rotate synchronously with the roller 31.

[0041] The roller 31 and the conveyor belt 32 also need to maintain good friction to avoid slippage. For this purpose, the outer periphery of the roller 31 is provided with soft rubber material 33 to enhance friction. Secondly, in order to maintain good conveying effect, the conveyor belt 32 is generally taut and has very little deformation. Therefore, the outer periphery of the roller 31 is provided with soft rubber material 33 so that when the second contact part 22 enters the clamping position, it can slightly squeeze the soft rubber material 33 to deform it and enter it. In addition, the conveyor belt has two fixing rods distributed on the corresponding sides.

[0042] In this embodiment of the utility model, the length of the main body 1 is less than the length of the first support part 13 and the second support part 14. An installation space 16 is formed between the first support part 13 and the second support part 14 at both ends. A limiting component 4 is installed in the two installation spaces 16 to limit the position of the clamp.

[0043] More specifically, the limiting component 4 includes at least one first cylinder 41 and at least one second cylinder 42 respectively installed in two installation spaces 16. The output ends of the first cylinder 41 and the second cylinder 42 can extend out of the first support portion 13 and abut against the clamp body 2. The number of the first cylinder 41 and the second cylinder 42 is specifically determined according to the number of clamps. Assuming that there are two clamps, the number of the first cylinder 41 and the second cylinder 42 is one each. They are distributed to limit the position of the clamp body 2 and release the corresponding clamp body 2 according to actual needs. The spacing between the clamp bodies 2 can be adjusted by different release timings. Preferably, a limiting groove 23 is provided on the first contact portion 21 of the clamp body 2, which extends into the interior of the clamp body 2 to limit its position, resulting in a better limiting effect.

[0044] Furthermore, at least two third cylinders 43 are installed in at least one of the installation spaces 16. The two third cylinders 43 are symmetrically arranged, and their output ends can extend out to abut against the second contact part 22. It should be noted that the two third cylinders 43 are installed downwards and extend to a position close to the second support part 14 to limit the position of the clamp body 2 from below. Together with the first cylinder 41 and the second cylinder 42 mentioned above, the entire conveying mechanism is provided with at least three places for limiting the position of the clamp body 2. The specific functions can be adjusted according to the actual situation to make the overall functions richer. In addition, the limiting components are integrated into the installation space 16 in the form of modules, so that the conveying mechanism integrates more functions and has a smaller volume.

[0045] It should be noted that since the second support portion 14 does not have a channel 15 at the position where it extends out of the main body 1, in order to prevent the clamp body 2 from jumping when entering the second support portion 14, a mounting plate 44 is provided in the limiting assembly 4 above the second support portion 14, and a channel 15 is also formed between the two. Moreover, the mounting plate 44 can serve as a mounting carrier for each cylinder.

[0046] In this embodiment of the utility model, a plurality of position sensors 5 are installed on the main body 1, and a notch 24 is provided on one side of a plurality of clamps to cooperate with the position sensors 5. The moving position of each clamp is obtained by the cooperation of the position sensors 5 and the notch 24, so as to facilitate better adjustment.

[0047] In this embodiment of the utility model, the main body 1 is an aluminum profile, and baffles 11 are installed on both sides of the main body 1 to provide support for the rollers 31. The baffles 11 have openings 12 at the positions corresponding to the limiting components 4, which mainly provide outlets for the air pipes of each cylinder.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
