Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of conveying equipment, in particular to a conveying device for automatic storage of plastic parts. BACKGROUND

[0002] As a basic element indispensable in modern industry, plastic parts are widely used in many fields such as automobiles, household appliances, consumer electronics, medical devices, etc. With the promotion of industrial upgrading and "Industry 4.0", the manufacturing industry has increasingly high requirements for production efficiency and intelligentization. The automated warehouse has become a core component of the enterprise logistics and warehousing system. In this system, the conveying device, as the "artery" connecting the production line, the storage area and the loading area, directly affects the throughput efficiency and operational reliability of the entire warehousing system.

[0003] Currently, the plastic part conveying device usually uses a conveying belt structure for conveying. One end of the conveying belt structure is placed under the discharge part of the plastic part processing equipment. The plastic parts directly fall from the discharge port onto the conveying belt. Due to the inertia of the plastic parts and the impact on the conveying belt structure, the plastic parts are easily bounced out of the end of the conveying belt structure due to the rebound effect of the conveying belt structure.

[0004] To solve the above problems, the existing patent CN119796874A discloses a connector plastic part anti-falling conveying device, which relates to the technical field of processing and conveying devices. It includes a belt conveying component, a material receiving rod holder, and a material falling rack body. The belt conveying component includes two belt wheel parts and a conveying belt wrapped between the two belt wheel parts. The outer surface of the conveying belt has multiple equally spaced pusher units. The top of the material receiving rod holder has two guide rod parts, and a material receiving frame assembly is arranged between the two guide rod parts. The material receiving frame assembly includes a material receiving frame body and two side sliding blocks. Two groups of side connecting plates are arranged between the material receiving rod holder and the material falling rack body, and each side connecting plate is provided with multiple anti-falling guard plate assemblies. The connector plastic parts on the processing equipment can be orderly guided to the belt conveying component by the material receiving frame assembly, which can prevent the connector plastic parts from bouncing out of the belt conveying component, ensure the orderly conveying, improve the processing efficiency of the connector plastic parts, and have strong practicality.

[0005] Although the above-mentioned scheme solves the problem of bouncing out of the plastic parts due to inertia and rebound when falling onto the conveying component, it still sets a rotatable material falling guide assembly at the tail end of the conveying structure to guide the longer plastic parts. However, the material guiding baffle is rotatably arranged. After the plastic parts are discharged, the material guiding baffle will reset under the action of its own weight. During the resetting process, it will block and hit the subsequent conveyed plastic parts, eventually causing the conveyed plastic parts to be in disarray, and the discharging effect is poor.

[0006] Therefore, we propose a conveying device for automatic storage of plastic parts. SUMMARY

[0007] To solve the above technical problems, the application provides an automatic storage conveying device for plastic parts, which comprises a conveying belt body, a supporting rod fixedly connected to the discharging end of the conveying belt body, a circulating material guiding unit rotatably arranged on the supporting rod, two supporting rods arranged on the two sides of the conveying belt body respectively, and a storage hopper arranged between the two supporting rods. The circulating material guiding unit comprises a rotating shaft and a plurality of material guiding plates movably arranged outside the rotating shaft.

[0008] In some embodiments, a supporting arm is fixedly arranged on each of the two supporting rods, a motor is mounted on one of the supporting arms, and the output end of the motor is in transmission connection with the rotating shaft.

[0009] In some embodiments, a sleeve is arranged outside the rotating shaft, a plurality of connecting plug plates are fixedly connected to the outside of the sleeve, the connecting plug plates are arranged in a circumferential array outside the sleeve, notches are formed in the end portions of the connecting plug plates, and the material guiding plates are inserted into the notches at one end.

[0010] In some embodiments, a connecting key is fixedly arranged outside the rotating shaft, and a key groove is formed in the inside of the sleeve.

[0011] In some embodiments, bolt holes are formed in the end portions of the connecting plug plates and the material guiding plates, and the material guiding plates are fixedly mounted on the plug plates through bolts.

[0012] In some embodiments, a plurality of rollers are rotatably arranged on the surface of the material guiding plate.

[0013] In some embodiments, a sliding groove is formed in the material guiding plate, an extension plate is slidably arranged in the sliding groove, a positioning member is arranged on the side wall of the material guiding plate to lock the position of the extension plate, a spring rod is mounted in the material guiding plate, and the two ends of the spring rod are fixedly connected with the material guiding plate and the extension plate respectively.

[0014] In some embodiments, positioning grooves are formed in the two sides of the extension plate, two positioning members are embedded in the two sides of the material guiding plate respectively, cavities are arranged in the two sides of the material guiding plate, the positioning member comprises a positioning rod slidably arranged in the cavity, an inclined surface is formed in the end portion of the positioning rod, the bottom end of the positioning rod slidably penetrates through the bottom of the cavity and extends into the positioning groove, a follow-up magnetic plate is arranged at the top end of the positioning rod, a connecting spring is further arranged outside the positioning rod, and the two ends of the connecting spring are connected with the bottom of the cavity and the follow-up magnetic plate respectively.

[0015] In some embodiments, the front end surface of the extension plate is roughened.

[0016] In some embodiments, the front end of the extension plate and the guide plate are provided with a plurality of avoiding grooves.

[0017] The present application has at least the following advantages: 1. Each guide plate is responsible for guiding one plastic part in its working cycle, which completely separates the front and rear workpieces in space and time, fundamentally eliminating the technical problems of "blocking" and "slapping" of the rear workpiece caused by the reset of the guide baffle in the original device, ensuring the continuity and high orderliness of the conveying and discharging; 2. By matching the speed of the conveying belt and the guide plate, the linear speed of the conveying belt is slightly faster than the rotational linear speed of the end of the guide plate, which promotes the smooth transition of the plastic part from horizontal conveying to inclined posture before it leaves the conveying belt. This "gradual inclination" process enables the center of gravity of the plastic part to move smoothly out of the conveying belt, avoiding collisions, bouncing or posture confusion caused by sudden falling. The multiple rollers on the surface of the guide plate convert sliding friction to rolling friction, further ensuring smooth sliding and effectively preventing scratches on the surface of the plastic part.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] Embodiment 1: please refer to Figures 1-6 The present application provides a technical solution: The present application provides a technical solution: An automatic conveying device for warehouse storage of plastic parts, comprising a conveying belt body 1, the conveying belt body 1 comprising a conveying belt, a material receiving rod frame, a material receiving frame assembly and a fall prevention guard plate assembly, all of the above structures are prior art and have been fully disclosed in patent 202510051360.2, which will not be described here again, the lower end of the conveying belt body 1 is fixedly connected with a supporting rod 2, a circulating lead material unit is rotatably arranged on the supporting rod 2, the supporting rod 2 is used for stably supporting the circulating lead material unit, the supporting rod 2 is provided with two and located at the two sides of the conveying belt body 1 respectively, a warehouse hopper 3 is arranged between the two supporting rods 2, the plastic parts are conveyed by the conveying belt and guided into the warehouse hopper 3 by the circulating lead material unit, and finally the warehouse hopper 3 is lifted into the automatic warehouse by the elevator; The circulating lead material unit comprises a rotating shaft 4 and a plurality of lead material plates 5 movably installed outside the rotating shaft 4, the rotating shaft 4 drives the lead material plates 5 to rotate, when the conveying belt conveys the plastic parts to the end thereof, the end of the plastic parts abuts against the lead material plates 5, and the conveying speed of the conveying belt is slightly faster than the linear speed of the end of the lead material plates 5 during conveying, therefore, with the continuous conveying, the end of the plastic parts abutting against the lead material plates 5 will rise along the lead material plates 5, when the plastic parts are separated from the conveying belt, the plastic parts can slide down along the surface of the lead material plates 5 to realize discharging.

[0022] Two support rods 2 are fixedly provided with support arms 6, the bottom end of the support arm 6 is fixedly connected with a connecting seat, a bolt hole is formed in the connecting seat, the support arm 6 is connected with the support rod 2 through a bolt, the rotating shaft 4 is rotatably arranged on the support arm 6, a motor is arranged on one of the support arms 6, the output end of the motor is drivingly connected with the rotating shaft 4, the rotating speed of the motor needs to be calculated and set, to ensure that the linear speed of the end of the material guide plate 5 is slightly lower than the conveying speed of the conveying belt after the rotating shaft 4 and the material guide plate 5 are driven to rotate, the setting of the rotating speed of the motor is prior art, and will not be repeated here.

[0023] Embodiment 2: please refer to Figures 4-7 The application provides a technical scheme: A kind of automatic storage conveying device for plastic parts, rotating shaft 4 outside is equipped with sleeve 7, rotating shaft 4 outside is provided with connecting key 9, key groove is formed in the inside of sleeve 7, both are connected by key to be able to stably drive sleeve 7 to rotate when rotating shaft 4 rotates, sleeve 7 outside is fixedly connected with multiple connection plug-in plates 8, multiple connection plug-in plates 8 are arranged in circumferential array on the outside of sleeve 7, slot is formed in the end of connection plug-in plate 8, material guide plate 5 one end is inserted with slot; The key connection between rotating shaft 4 and sleeve 7 not only considers the rotation drive between the two, but also ensures that the two can be easily disassembled and connected, in actual use, the number of connection plug-in plates 8 corresponds to the number of material guide plates 5, and the material guide plates 5 are used to support the plastic parts, so the spacing between the material guide plates 5 will be adjusted accordingly as the length of the plastic parts changes, and then the material guide plates 5 and the connection plug-in plates 8 are arranged in a separated manner, so when the number of material guide plates 5 needs to be adjusted, the material guide plates 5 that need to be disassembled can be removed from the connection plug-in plates 8. In order to further adapt to the adjustment requirement of material guide plate 5, sleeve 7 can also be disassembled from rotating shaft 4 and replaced with a suitable sleeve 7, it should be noted that the material guide plates 5 on the outside of sleeve 7 are always distributed in equidistant circumferential array, which can ensure that the spacing between each material guide plate 5 is the same, suitable for conveying the same batch of plastic parts.

[0024] Bolt holes are formed in the end of connection plug-in plate 8 and material guide plate 5, the material guide plate 5 is fixedly installed on the plug-in plate through a bolt, this modular plug-in and bolt fixing structure not only ensures the firmness of the connection, but also facilitates on-site quick replacement of a specific specification or maintenance of a single material guide plate 5, greatly improving the maintainability and adaptability of the equipment.

[0025] A plurality of rollers 10 are rotatably arranged on the surface of the material guide plate 5, which can make the plastic parts slide more smoothly along the surface of the material guide plate 5 after abutting against the material guide plate 5 at one end.

[0026] The motor drives the whole cycle of the lead unit to rotate at a constant speed. When one lead plate 5 rotates to the surface of the conveyor belt body 1, the plastic part sent by the conveyor belt is pushed by the conveyor belt, and the other end is abutted on the lead plate 5. Due to the speed difference, the plastic part is pushed forward while the end abutting on the lead plate 5 is subjected to a backward and upward force, causing the plastic part to rotate slightly around the contact point with the conveyor belt. The end of the plastic part abutting on the lead plate 5 gradually slides upward along the plate surface, and the whole plastic part presents an inclined and lifted posture. This "gradual inclination" process is crucial, as it allows the center of gravity of the plastic part to move smoothly out of the conveyor belt, preparing for smooth sliding, rather than sudden falling. This process benefits from the multiple rollers 10 arranged on the surface of the lead plate 5, which convert sliding friction into rolling friction, making the movement smoother and effectively preventing scratches on the surface of the plastic part. When the plastic part is conveyed to the point where its center of gravity is completely over the edge of the conveyor belt, it slides smoothly into the lower storage hopper 3 under the action of gravity, completing the discharging process. Each lead plate 5 is responsible for guiding one plastic part during its rotation cycle, thereby completely isolating the front and rear workpieces in space and time, and eliminating the interference problem caused by the single baffle reset in the prior art.

[0027] Example 3: Please refer to Figures 8-10 The present application provides a technical solution: An automatic storage conveying device for plastic parts, the lead plate 5 is provided with a sliding groove 11, the sliding groove 11 is provided with an extension plate 12, the side wall of the lead plate 5 is provided with a positioning member for locking the position of the extension plate 12, the lead plate 5 is provided with a spring rod 13, and the two ends of the spring rod 13 are fixedly connected with the lead plate 5 and the extension plate 12.

[0028] The positioning groove 14 is arranged on both sides of the extension plate 12, the positioning member is arranged on both sides of the material guiding plate 5, the material guiding plate 5 is provided with a cavity, the positioning member comprises a positioning rod 15 which is slidably arranged in the cavity, the end of the positioning rod 15 is provided with an inclined surface, the bottom end of the positioning rod 15 is slidably penetrated through the bottom of the cavity and extends into the positioning groove 14, so that the extension plate 12 cannot slide out of the material guiding plate 5 when the positioning rod 15 is inserted into the positioning groove 14, the top end of the positioning rod 15 is provided with a follow-up magnetic plate 16, the outer side of the positioning rod 15 is further provided with a connecting spring 17, the two ends of the connecting spring 17 are connected with the bottom of the cavity and the follow-up magnetic plate 16 respectively, when the follow-up magnetic plate 16 moves out of the cavity, it drives the positioning rod 15 to disengage from the positioning groove 14, thereby releasing the limitation of the extension plate 12, the support rod 18 is fixedly arranged at the bottom of the support arm 6, the inner side of the support rod 18 is fixedly provided with a fixed magnetic block 19, the fixed magnetic block 19 can attract the follow-up magnetic plate 16, as the material guiding plate 5 continuously rotates, when it rotates through the fixed magnetic block 19, the fixed magnetic block 19 attracts the follow-up magnetic plate 16 to move, thereby driving the positioning rod 15 to move out of the positioning groove 14, so that the extension plate 12 slides out of the material guiding plate 5, and the position of the fixed magnetic block 19 is still a certain distance away from the end of the conveying belt, and the opening of the material guiding plate 5 is also downward when it rotates to this position, so that the extension plate 12 slides out under the action of gravity when it is released from the limitation, and the extension plate 12 will return to the material guiding plate 5 again under the action of gravity when the material guiding plate 5 rotates to the upper position, and is locked by the positioning rod 15 again.

[0029] The front end surface of the extension plate 12 is roughened to ensure that the plastic part can obtain sufficient friction force in the initial guiding stage to prevent slipping.

[0030] The front end of the extension plate 12 and the material guiding plate 5 is provided with a plurality of avoiding grooves, in the prior art, a plurality of stop blocks are arranged on the surface of the conveying belt to push the plastic part, so that the avoiding grooves are arranged at the corresponding positions of the extension plate 12 and the material guiding plate 5 to ensure that they do not interfere with each other.

[0031] It should be noted that, in the present text, relational terms such as first and second and the like can only be used to distinguish one entity or operation from another entity or operation, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Moreover, the terms "comprises", "comprising" or any other variant thereof are intended to cover non-exclusive inclusions, so that a process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such a process, method, article or equipment.
