Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automation production, especially to a line body rack connecting structure and conveyor. BACKGROUND

[0002] Conveyors play a vital role in many fields such as food production, logistics, and automation processing. As an important part of the equipment assembly line, they effectively realize the horizontal linear transportation of workpieces or materials. In the traditional equipment assembly line production process, due to the differences in the specific needs of each set of equipment assembly line for the conveyor (such as length, orientation, transportation height, transportation method, etc.), the conveyor manufacturer often needs to provide non-standard customization services for customers. Although this customization requirement meets the individual needs of customers, it also brings the problem of low production efficiency.

[0003] To this end, the conveyor produced by the current conveyor industry generally adopts modular design, that is, the line body rack (and other key components) of the conveyor is divided into multiple independent single modules. Each single module has a specific function and size, and can be flexibly combined and adjusted according to different application scenarios and customer requirements, while not losing the customization ability, so that the conveyor can use a large number of prefabricated standard modules in the production process, thereby greatly shortening the delivery cycle and improving the production efficiency.

[0004] However, in the application process of the current modular design conveyor, we face a significant problem: although the detachable fixed connection by using bolts and other fasteners ensures the close and reliable connection between the modules of the conveyor and the overall structural strength of the conveyor rack finally assembled, this connection method brings inconvenience in actual application. Especially in the process of equipment production and sales and subsequent customer self-adjustment of production line layout, the conveyor often needs to be disassembled and reassembled, especially the conveyor rack of large assembly line is usually heavy, and it is extremely difficult to disassemble and reconnect using bolts and other fasteners, which is time-consuming and laborious, and seriously hinders the shortening of the implementation and debugging period.

[0005] In short, although the current modular design conveyor ensures the stability and strength of the structure when connected by using bolts and other fasteners, the installation and disassembly process is complicated and time-consuming, which undoubtedly has an adverse effect on production efficiency and flexibility.

[0029] Embodiment one

[0030] Reference Figure 1 A line body rack connecting structure, like the line body rack connecting structure of the existing modular design conveyor, comprises a plurality of groups (at least two groups) of rack modules 1 arranged in sequence along the horizontal transverse direction, each group of rack modules 1 comprises at least two groups of rack units 11 arranged in parallel and spaced apart from each other, at least one connecting rod 12 for connecting the two groups of rack units 11, adjacent rack modules 1 are detachably connected to each other, so that the plurality of groups of rack modules 1 constitute a line body rack assembly 2.

[0031] Reference Figures 1-3The difference between the conveyor of the application and the conveyor of the prior art is that the connection between the rack modules 1 is optimized, that is, the adjacent rack modules 1 are detachably connected by hooking. Specifically, one end of each rack monomer 11 of each rack module 1 is provided with an ear 13, and the other end of each rack monomer 11 away from the ear 13 is fixedly or movably provided with a hook plate 14, the hook plate 14 extends outward to form a hooking body 141, and the bottom of the hooking body 141 is recessed inward to form a connecting groove 142 for hooking the ear 13. During work, only the connecting groove 142 of a rack module 1 is connected by hooking on the ear 13 of the adjacent rack module 1 by moving the rack module 1 and / or the hook plate 14 thereon, so that the two adjacent rack modules 1 are connected to each other, and when disassembled, the fasteners do not need to be disassembled, only the ear 13 is separated from the connecting groove 142 by moving the rack module 1 and / or the hook plate 14 thereon again, so that the two rack modules 1 are separated.

[0032] Through the above technical solution, the adjacent rack modules 1 are detachably connected by hooking, and during installation and disassembly, a large number of fasteners and tools are not needed, only the ear 13 is connected or separated from the connecting groove 142 by moving a single rack module 1 and / or the hook plate 14 thereon, so that the connection and separation between the rack modules 1 are completed, greatly simplifying the installation and disassembly process of the conveyor line rack, which is beneficial to shorten the time cost of the conveyor during production, sales and debugging, and is easy to adjust and maintain, and can be flexibly configured according to different scenes and customer needs.

[0033] Although the hooking direction can fix the plurality of rack modules 1 along the conveying direction of the conveyor, so that the plurality of rack modules 1 are connected like a string, when the application is applied to a light conveyor, that is, the overall mass of the conveyor is light, it is difficult to generate enough friction force by contacting the ground static friction to ensure that the adjacent rack modules 1 will not deviate laterally. To this end, the embodiment is further optimized: the inner side of each rack monomer 11 of each rack module 1 is provided with a limiting baffle 15, and the ear 13 is arranged on the limiting baffle 15. After the adjacent rack modules 1 are connected by hooking, the limiting baffle 15 can limit the rack module 1 in the horizontal longitudinal direction (that is, perpendicular to the conveying direction of the conveyor) by abutting against the inner side of the adjacent rack monomer 11, preventing the rack module 1 from deviating in the horizontal longitudinal direction, and ensuring the stability and reliability of the entire line rack assembly 2.

[0034] The scheme of limiting the rack module 1 laterally by the limiting baffle 15 is simple and effective, does not need additional fasteners or connecting pieces, only needs to provide direct limiting action through physical contact, does not need complex mechanical structures or control systems, and can reduce the risk of connection failure caused by loosening or wear of the fasteners due to mechanical vibration when the fasteners are used for lateral limiting.

[0035] It is considered that the precision error exists during production and assembly, the connecting groove 142 of the hook plate 14 and the lug 13 are worn due to mechanical vibration during equipment operation, and these factors can cause a gap between the connecting groove 142 and the lug 13 during use, cause the hooking body 141 to be disconnected from the lug 13, cause invalid connection between adjacent rack modules 1, and then reduce the stability of the line body rack assembly 2 during operation. To avoid the disconnection, the embodiment is further improved: the two ends of the connecting rod 12 of each group of rack modules 1 are rotatably connected to the rack body 11, and the hook plate 14 is arranged on the connecting rod 12; the hook plate 14 is connected with the elastic body 16; the end of the elastic body 16 away from the hook plate 14 is connected to the rack body 11 corresponding to the hook plate 14, and the elastic body 16 is used to generate an elastic force to drive the hooking body 141 to continuously abut against the lug 13.

[0036] Through the above technical scheme, the connecting rod 12 is rotatably connected to the rack body 11, and the hook plate 14 is arranged on the connecting rod 12. This design enables the hook plate 14 to have a certain range of motion when subjected to external force, thereby adapting to the effects of precision error and mechanical vibration. At the same time, the elastic force generated by the deformation of the elastic body 16 can drive the connecting groove 142 to continuously abut against the lug 13, and the tension generated by the elastic body 16 can compensate for the small gap between the connecting groove 142 and the lug 13 caused by precision error or mechanical vibration, thereby maintaining the tightness of the connection between the lug 13 and the connecting groove 142. Specifically, when a gap appears between the connecting groove 142 and the lug 13, the tension of the elastic body 16 will promote the hook plate 14 to rotate together with the connecting rod 12, so that the connecting groove 142 is tightly abutted on the lug 13 again, thereby avoiding disconnection and invalid connection, and enhancing the adaptability and stability of the hooking connection between adjacent rack modules 1.

[0037] In addition, to reduce the connection difficulty between the hook plate 14 and the lug 13, in the embodiment, the hooking body 141 is formed with a guide slope 143 for the lug 13 to abut against, and the guide slope 143 extends downward from the top end of the hooking body 141 to the connecting groove 142.

[0038] Through the above improvement, in actual operation, the staff does not need to lift the rack module 1 vertically. Only need to simply horizontally push the rack module 1, let the rack module 1 move along the horizontal transverse to the other group of rack module 1 which needs to be hooked. With the movement of the rack module 1, the hook plate 14 on it will hit the lug 13 of the target rack module 1 (i.e. the rack module 1 to be connected). Because the guide slope 143 extends downward from the top end of the hooking body 141 to the connecting groove 142, when the lug 13 hits the hook plate 14, it will first contact the guide slope 143 and generate an inclined upward thrust on the slope. Under the action of the thrust of the lug 13, the hook plate 14 will swing upward against the elastic force of the elastic member. At the same time, the lug 13 moves along the inclined direction of the guide slope 143, and finally smoothly drills into the connecting groove 142 at the bottom end of the hooking body 141. Through this series of simple actions, the hooking connection between the two groups of rack modules 1 can be realized. The above technical solution not only simplifies the connection process, reduces the difficulty of connection operation, but also improves the efficiency and stability of connection.

[0039] In addition, considering that in actual application process, the elastic member will be pre-compressed or stretched during installation, the elastic member is pre-tightened, so as to increase the upper limit of deformation of the elastic member after the connection of the lug 13 and the hook plate 14, increase the force applied by the elastic member to the hook plate 14, and enhance the connection tightness and hooking strength between the lug 13 and the connecting groove 142. This will bring a problem, that is, in the case that the hook plate 14 and the lug 13 are not connected, the elastic member needs to be pre-tightened to apply force to the hook plate 14, and under the action of the force, the relative position of the guide slope 143 of the hooking body 141 and the lug 13 is difficult to guarantee. When the pre-tightening degree of the elastic member is large, the position of the hooking body 141 will be vertically deviated downward, which is easy to cause that in the connection process, the lug 13 may directly collide with the top end of the hooking body 141 without entering the connecting groove 142 along the guide slope 143.

[0040] To this end, the embodiment is further improved: the rack unit 11 is provided with a limiting rod 17 located below the hooking body 141 for abutting against the hooking body 141 to longitudinally limit the hooking body 141. By setting the limiting rod 17, the hooking body 141 can be longitudinally limited by the limiting rod 17 when the two groups of rack modules 1 are not connected, so as to overcome the force applied by the elastic member to the hooking body 141, so that the guide slope 143 on the hooking body 141 can better face the lug 13, and ensure that the lug 13 can relatively and smoothly move along the guide slope 143 during the subsequent collision with the hook plate 14, lift the hooking body 141 and finally drill into the connecting groove 142.

[0041] In the embodiment, the hanging ear 13 comprises a hanging body part 131, one end of which is connected to the rack body 11, and the other end of which is rotatably connected with a rolling body 132. The hanging ear 13 rolls to contact the hooking body 141 and the connecting groove 142 through the rolling body 132. The rolling contact of the hanging ear 13 with the hooking body 141 and the connecting groove 142 through the rolling body 132 can significantly reduce the abrasion caused by the impact of the hanging ear 13 on the hook plate 14, prolong the service life of the hanging ear 13 and the hooking body 141, and enable the hanging ear 13 to more smoothly connect with the hooking body 141 and the connecting groove 142. In the embodiment, the rolling body 132 rotatably connected with the hanging ear 13 can have various embodiments, for example, the rolling body 132 can be various types of bearings, which are rotatably sleeved on the hanging body part 131 of the hanging ear 13 and rollably contact the hooking body 141 and the connecting groove 142 through the outer ring thereof.

[0042] In addition, the rolling body 132 is provided with an elastic layer 133, which can elastically abut against the hooking body 141 and the connecting groove 142. The elastic layer 133 is made of wear-resistant elastic materials, such as rubber, polyurethane or other synthetic materials. Through the provision of the elastic layer 133, the elastic layer 133 can absorb the vibration and impact generated by the collision and friction during the impact of the hanging ear 13 on the hook plate 14, reduce the noise, and reduce the abrasion of the surfaces of the hanging ear 13 and the hook plate 14. After the hanging ear 13 enters and hooks the connecting groove 142, the elastic layer 133 can form elastic contact between the hanging ear 13 and the connecting groove 142. The elastic layer 133 can elastically deform under the extrusion, increase the contact area between the hanging ear 13 and the connecting groove 142, and enable the hanging ear 13 to be filled and clamped in the connecting groove 142, compensate for the gap caused by the manufacturing tolerance or installation error, ensure the close fit between the connecting parts, and make the connection between the hanging ear 13 and the connecting groove 142 more tight and reliable.

[0043] In the embodiment, the hook plate 14 and the rack body 11 are provided with a hinge bolt 18, and the elastic body 16 is a tension spring with hooks at both ends. The tension spring hooks the hinge bolt 18 to detachably connect the hook plate 14 and the rack body 11. In use, the tension spring can detachably connect the hook plate 14 and the rack body 11 through the hooks, which is simple to install and can easily detach and replace the tension spring or the hinge bolt 18 during maintenance, thereby improving the maintainability of the equipment. In addition, the position of the hinge bolt 18 can be adjusted to change the tension of the tension spring or the connection angle, or different tension springs with different tension coefficients can be replaced to meet specific mechanical requirements.

[0044] The connecting rod 12 is provided with a handle 19. When it is necessary to detach and separate two adjacent rack modules 1, the handle 19 can be pulled to rotate the connecting rod 12 and drive the hook plate 14 to disengage from the hanging ear 13, thereby quickly realizing the connection and separation of the modules and improving the work efficiency and the convenience of operation.
