Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belts, and particularly relates to an annular conveying device. Background Art

[0002] There are many types of existing annular conveying lines. For example, annular guide rail conveying lines, precision link type annular guide rail conveying lines, and chain type conveying lines with accessories. Another example is that the patent document with the authorization publication number CN206813861U discloses an annular conveying slide rail device, which includes a double-V slide rail arranged in a ring, a plurality of slider positioning seats evenly installed on the double-V slide rail, a synchronous belt for driving the slider positioning seats to rotate synchronously, synchronous wheels installed at the front and rear ends of the synchronous belt for driving the synchronous belt to rotate, a speed reducer installed below the synchronous wheel, and a servo motor installed on the speed reducer; the slider positioning seat includes a horizontal plate, a positioning block installed at the upper end of the horizontal plate, a bushing installed in the middle of the horizontal plate, and a pulley installed at the bottom of the horizontal plate.

[0003] When the above device is in use, the servo motor and the synchronous belt are used in cooperation to drive the slider positioning seat, and the double-V slide rail is used to guide and limit the movement of the slider positioning seat. Specifically, the horizontal plate is located above the double-V slide rail, and the horizontal plate and the double-V slide rail are connected by rolling through the pulley. The annular movement of multiple slider positioning seats is in the vertical rotation axis direction. The self-weight of the horizontal plate and the positioning block can exert a positive pressure on the pulley towards the double-V slide rail, so that the pulley fits tightly with the double-V slide rail, ensuring that there is no position offset between the pulley and the double-V slide rail during operation, that is, ensuring that the slider positioning seat moves along the guiding track of the double-V slide rail during operation. However, this kind of annular movement with the action of the double-V slide rail will cause the device to occupy a large area. If the above double-V slide rail is simply rotated by ninety degrees to make the annular movement in the vertical rotation axis direction become the annular movement in the horizontal rotation axis direction for use, the problem of the large floor area of the device can be effectively solved; but during the annular movement in the horizontal rotation axis direction, the slider positioning seat located below will be affected by the self-weight of the horizontal plate and the positioning block below it and pull the pulley downward, and then the pulley and the synchronous belt will show a drooping phenomenon. This drooping phenomenon will cause the overall longitudinal annular movement track of the synchronous belt to deviate, that is, the position of the product on the slider positioning seat will deviate. When the slider positioning seat stops at the preset specified position later, there will be a position deviation at this specified position, resulting in the product not being accurately detected, etc. And if it lasts for a long time, the overall synchronous belt will be stretched and deformed, and the teeth on the inner side of the synchronous belt will wear faster, and then the service life of the synchronous belt will be greatly reduced, and the replacement cycle will become shorter.

[0004] Therefore, we propose an annular conveying device to solve the above problems. Content of the Utility Model

[0005] The purpose of the present utility model is to propose an annular conveying device to solve the problems in the prior art. By guiding and limiting the upper and lower sections of the conveyor belt, the conveyor belt can always maintain a straight and stable state during movement, so that the products on the conveyor belt can be accurately conveyed to the designated position without position deviation.

[0006] To solve the above problems, the present utility model provides the following technical solutions:

[0007] An annular conveying device includes a bearing frame with two parallel side parts, a conveyor belt arranged on the bearing frame, and a driving member for driving the conveyor belt to rotate. The conveyor belt is located between the two parallel side parts, and the rotation axis of the conveyor belt is arranged horizontally. The upper and lower sections of the conveyor belt respectively form a heavy-load section and a return section. Guide strips are arranged on the tops of the two parallel side parts, and limit strips are arranged on the bottoms of the two parallel side parts. Along the conveying direction, the two guide strips are respectively used to support both sides of the heavy-load section, and the two limit strips are respectively used to support both sides of the return section.

[0008] As a further solution of the present utility model: It further includes multiple fixture plates. The conveyor belt is set in two groups. The two ends of the fixture plates are respectively installed on the two groups of conveyor belts, and multiple fixture plates are arranged equidistantly on the two groups of conveyor belts, so that the two groups of conveyor belts and multiple fixture plates together form a plate chain conveyor belt; the upper section of the plate chain conveyor belt forms the heavy-load section, and the two guide strips are respectively arranged corresponding to the two groups of conveyor belts; multiple extension blocks are arranged on both sides of the plate chain conveyor belt along its length direction, and the multiple extension blocks are equidistantly distributed. The lower section of the plate chain conveyor belt and the multiple extension blocks located on the lower section of the plate chain conveyor belt together form the return section, and the two limit strips are respectively used to support the extension blocks on both sides of the return section.

[0009] As a further solution of the present utility model: The guide strip is arranged along the length direction of the parallel side part, and a receiving groove for supporting the conveyor belt is opened on the guide strip along its length direction.

[0010] As a further solution of the present utility model: The extension block is fixedly arranged at the end of the fixture plate, and one end of the extension block located on the lower section of the plate chain conveyor belt extends to the top of the limit strip and abuts against it.

[0011] As a further solution of the present utility model: The layouts of the guide strip and the limit strip are staggeredly distributed in the vertical direction, so that the lower section of the plate chain conveyor belt is far away from the limit strip.

[0014] As a further solution of the present invention: the conveyor belt is configured as a synchronous belt.

[0015] As a further solution of the present invention: the extension block is configured as a wear-resistant block.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Through the setting of the guide strips and the limit strips, during the movement of the conveyor belt, the receiving grooves on the guide strips can support and limit the heavy-load section of the conveyor belt, and the limit strips can support and limit the empty section of the conveyor belt. The coordinated setting of the two can keep the conveyor belt in a taut state at all times.

At the same time, the setting of the extension block can make the lower section of the plate chain conveyor belt away from the limit strip, avoiding the limit strip from interfering with the movement of the lower section of the plate chain conveyor belt.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0029] As Figures 1 - 7 shown, an annular conveying device includes a carrying frame 1 having two parallel sides 101, a conveyor belt 2 provided on the carrying frame 1, and a driving member 3 for driving the conveyor belt 2 to rotate. The conveyor belt 2 is located between the two parallel sides 101, and the rotation axis of the conveyor belt 2 is arranged in the horizontal direction. The upper and lower sections of the conveyor belt 2 respectively form a heavy load section and a return section. As Figure 1 shown, the parallel sides 101 on both sides are used to support the entire device, and the heavy load section of the conveyor belt 2 is used to carry products and convey the products for a specified distance.

[0030] In the above conveying process, in order to ensure that the conveyor belt 2 will not be stretched and deformed by the products, guiding strips 4 are provided at the tops of the two parallel sides 101 in the present utility model, and limiting strips 5 are provided at the bottoms of the two parallel sides 101. Along the conveying direction, the two guiding strips 4 are respectively used to support both sides of the heavy load section, and the two limiting strips 5 are respectively used to support both sides of the return section. Through the arrangement of the guiding strips 4 and the limiting strips 5, both the heavy load section and the return section of the conveyor belt 2 can be supported and limited. Therefore, when the products are placed on the heavy load section, the pressing of the products on the conveyor belt 2 will not cause the conveyor belt 2 to deform, so that the conveyor belt 2 can always maintain a straight and stable state during the movement process. Thus, the products on the conveyor belt 2 can be accurately conveyed to the specified position without any position deviation.

[0031] As Figures 1 - 3As shown, during actual use, this conveying device can adapt to different application scenarios. To illustrate this conveying device in detail, in this embodiment, a plate chain conveyor belt is taken as an example. Specifically, the present utility model further includes multiple fixture plates 8. The conveyor belt 2 is set in two groups. The two ends of the fixture plate 8 are respectively installed on the two groups of conveyor belts 2, and multiple fixture plates 8 are arranged at equal intervals on the two groups of conveyor belts 2, so that the two groups of conveyor belts 2 and multiple fixture plates 8 together form a plate chain conveyor belt.

[0032] Based on the above plate chain conveyor belt, the heavy load section and the return section are respectively arranged as follows:

[0033] 1) Heavy load section: The upper section of the plate chain conveyor belt constitutes the heavy load section. The two guiding long strips 4 are respectively arranged corresponding to the two groups of conveyor belts 2. The guiding long strips 4 are arranged along the length direction of the parallel side part 101, and a receiving groove 6 for supporting the conveyor belt 2 is formed along the length direction of the guiding long strip 4. During the use of the conveying device, the receiving groove 6 on the guiding long strip 4 always supports and limits the heavy load section. The bottom of the conveyor belt 2 always runs on the receiving groove 6, thereby avoiding the situation that the conveyor belt 2 is deformed due to being pressed by the product.

[0034] 2) Return section: Multiple extension blocks 7 are arranged on both sides of the plate chain conveyor belt along its length direction, and the multiple extension blocks 7 are evenly distributed. The lower section of the plate chain conveyor belt and the multiple extension blocks 7 located on the lower section of the plate chain conveyor belt together form the return section. The two limiting long strips 5 are respectively used to support the extension blocks 7 on both sides of the return section. The extension blocks 7 are fixedly arranged at the ends of the fixture plate 8, and one end of the extension block 7 located on the lower section of the plate chain conveyor belt extends to the top of the limiting long strip 5 and abuts against it. During the use of the conveying device, the limiting long strip 5 can support and limit the extension block 7, so that the entire return section is lifted upward and does not show a sagging phenomenon.

[0035] In summary, under the combined action of the guiding long strip 4 and the limiting long strip 5, the heavy load section and the return section of the conveying device can always be supported and limited, so that the conveyor belt 2 always maintains a taut state. Even if products are placed on the heavy load section subsequently, the pressing of the product weight on the heavy load section will not cause the heavy load section to sag and deform, and the conveying device can still accurately convey the products to the designated position.

[0036] It should be noted that the jig plate 8 on the plate chain conveyor belt in this embodiment can be used in conjunction with a corresponding carrier during use. The carrier is used to place products that are compatible with it. The carrier and the jig plate 8 can be positioned and matched by positioning pins and other positioning methods, so that the position of the carrier placed on the jig plate 8 always remains constant, that is, to ensure that the position of the product on the jig plate 8 is constant. After the subsequent conveying device drives the product to the designated position and pauses, the processing device such as the robot next to the conveying device can perform corresponding processing on the product at that position.

[0037] like Figures 4 - 5 As shown, the layout of the guide strip 4 and the limiting strip 5 is staggered in the vertical direction so that the lower section of the plate chain conveyor belt is away from the limiting strip 5. On the one hand, this arrangement can ensure that the movement of the return section will not be interfered with by the limiting strip 5. On the other hand, it is convenient to install the extension block 7 on the jig plate 8, and the extension block 7 can contact the top of the limiting strip 5.

[0038] like Figure 2 As shown, for the setting of the above-mentioned conveyor belt 2, a rotating roller 9 can be rotatably set on the supporting frame 1, and the rotating axis of the rotating roller 9 is arranged in the horizontal direction. The conveyor belt 2 is sleeved on the rotating roller 9, and the driving member 3 is used to drive the rotating roller 9 to rotate.

[0039] Furthermore, the drive element 3 includes a servo motor mounted on the support frame 1 and connected to the rotating roller 9. This servo motor allows the conveyor belt 2 to be paused at any desired position. Of course, the servo motor in this embodiment can also be replaced with a stepper motor, etc. Preferably, the conveyor belt 2 is configured as a synchronous belt, and the extension block 7 is configured as a wear-resistant block. The use of the synchronous belt and wear-resistant block increases the service life of the conveyor device and extends maintenance cycles.

[0040] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
