Description

Technical Field

[0001] This utility model relates to the field of sorting machine technology, specifically to an automatic counting spring sorting machine. Background Technology

[0002] Currently, springs, as a common basic component in mechanical parts, are widely used in many fields such as automobiles, home appliances, precision instruments, and construction machinery. To ensure the consistency of spring quality during use, springs are usually counted and sorted one by one on the production line.

[0003] In existing technologies, the common methods are manual counting and sorting, or using simple conveyor mechanisms to sequentially feed the springs into the collection container. Manual operation is not only inefficient and labor-intensive, but also prone to counting errors or inaccurate sorting due to human negligence. While some equipment incorporates rotating tables or conveyor belts for automatic feeding, their lack of effective design in spring arrangement and limiting leads to springs easily stacking, jamming, or shifting in position, thus affecting counting accuracy and the stability of subsequent sorting.

[0004] In the sorting process, most existing equipment uses a single mechanical baffle or simple lever to separate and unload the springs. These mechanisms typically have simple movements, making it difficult to achieve precise control over individual springs and unable to distinguish between qualified and unqualified products, resulting in insufficient reliability of the sorting results. In addition, traditional equipment generally lacks intelligent detection and counting methods, relying on manual verification, which is inefficient and cannot meet the needs of mass production and automation.

[0005] Therefore, there is an urgent need for a device that can achieve automatic feeding, single-column arrangement, real-time counting, intelligent sorting, and automatic discharge to improve the accuracy and production efficiency of spring sorting. Utility Model Content

[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0007] Therefore, the technical solution adopted by this utility model is as follows: an automatic counting spring sorting machine, including a base, a sorting rail group, a sorting material group, and a turntable. An input conveyor belt and an output conveyor belt are respectively provided on both sides of the base. The input conveyor belt is connected to the feed inlet, and the output conveyor belt corresponds to the discharge outlet, used to realize continuous feeding and discharging of springs. The sorting rail group includes an outer guide edge, an inner guide edge, and several connecting girders, used to define the conveying trajectory of the springs and form a slide. Counting sensors are fixedly installed on the surface of the connecting girders for counting the springs one by one. The sorting material group is evenly distributed on the surface of the outer guide edge, responsible for the separation and discharging of individual springs. A motor-driven turntable is provided inside the base. The surface of the turntable is roughened, and the springs move synchronously through friction. Through the above overall structure, automatic feeding, single-row arrangement, real-time counting, and accurate sorting of springs can be ensured, improving the overall automation level.

[0008] In a preferred embodiment, the outer guide edge is further configured such that its bottom surface is fixed to the base surface and located on the edge surface of the turntable; a suspension gap is provided between the bottom surface of the inner guide edge and the top surface of the turntable. Specifically, this structure can prevent the inner guide edge from directly contacting the turntable, prevent frictional interference, and ensure smooth and stable rotation of the turntable.

[0009] In a preferred embodiment, the configuration is further as follows: a fixed guide plate is fixedly mounted on the surface of the machine base. One end of the fixed guide plate is rotatably connected to the axis of the turntable via a pin and fixed to the top surface of the machine base. A gap is provided between the bottom surface of the fixed guide plate and the top surface of the turntable. One end of the fixed guide plate has a slot communicating with the inner side of the outer guide rail for the passage of a single spring. Specifically, this structure ensures that the springs are guided into the slide rail one by one, avoiding jamming caused by multiple springs entering simultaneously, thus improving the accuracy and stability of feeding.

[0010] In a preferred embodiment, the width of the slide is equal to the diameter of a single spring, the inner guide edge is a semi-circular or 3 / 4-circular strip, and both the outer and inner guide edges are arranged concentrically with the turntable. Specifically, this structure enables the springs to advance in a single row within the slide, avoiding spring overlap or interleaving and ensuring the smoothness of the sorting process.

[0011] In a preferred embodiment, the surfaces of the inlet and outlet are located in the same plane as the turntable, with the inlet connected to the input conveyor belt and the outlet connected to the output conveyor belt. Specifically, this structure enables smooth spring connection, avoids misalignment between upstream and downstream conveying links, and improves the overall production line's connection efficiency.

[0012] In a preferred embodiment, the sorting assembly is further configured as follows: The sorting assembly includes a discharge hopper, a lever, and a servo motor. One end of the discharge hopper is fixedly connected to the surface of the outer guide edge, and a spring valve is fixedly installed on the inner side of the discharge hopper. The spring valve is a flexible sheet-like material, normally located in the same vertical plane as the outer guide edge, used to seal the port of the discharge hopper and guide the spring to move along the slide. Specifically, this structure ensures that the spring passes stably when not sorting and can open promptly when sorting is required.

[0013] In a preferred embodiment, the paddle is rotatably mounted on the surface of the discharge hopper, and a servo motor drives the paddle to rotate. The movement of the paddle pushes a single spring within the chute out through the discharge hopper, simultaneously causing the spring valve to deflect elastically, thus rejecting defective products. Specifically, this structure ensures the accuracy of the sorting action and improves the reliability of the sorting results.

[0014] In a preferred embodiment, the connecting truss is further configured as follows: a portal frame structure is used for the connection between the outer and inner guide edges, and a visual recognition component is fixedly mounted on the surface of the connecting truss. The visual recognition component can perform image recognition on the passing springs, achieving intelligent sorting in conjunction with the sorting mechanism. Specifically, this structure can improve the intelligence level of the sorting machine and achieve quality control based on visual inspection.

[0015] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, through the coordinated operation of the input conveyor belt, turntable, outer guide edge, inner guide edge and fixed guide plate, the springs can enter the slide in sequence and maintain a single-row orderly conveying. Furthermore, the counting sensor enables counting one by one, ensuring the stability and accuracy of the feeding and counting process. This avoids the problems of low efficiency and large error in traditional manual counting, thereby improving the level of automated production.

[0016] 2. In this utility model, the combination structure of the discharge hopper, the lever, the servo motor and the spring valve in the sorting group realizes the precise separation and directional discharge of individual springs in the slide. With the assistance of the visual recognition component, it can complete the rejection of unqualified products, thereby ensuring the reliability and consistency of the sorting results and significantly improving product quality and production efficiency.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0020] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0021] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an automatic counting spring sorting machine.

[0022] Combination Figures 1-4 As shown, this utility model provides an automatic counting spring sorting machine, including a base 100, a sorting rail assembly 200, a sorting material assembly 300, and a turntable 400. The base 100 has an input conveyor belt 110 and an output conveyor belt 120 on both sides. The input conveyor belt 110 transports the springs to be sorted to the feed inlet 201 of the sorting rail assembly 200, and the output conveyor belt 120 receives the sorted springs and transports them to subsequent processes, thus achieving automatic connection between upstream and downstream processes. The sorting rail assembly 200 includes an outer guide edge 210, an inner guide edge 220, and several connecting girders 230. The outer guide edge 210 and the inner guide edge 220 are concentrically arranged to jointly define a slide 202. The width of the slide 202 is equal to the diameter of a single spring, ensuring that the springs pass through it stably one by one. The connecting truss 230 is used to connect the outer guide edge 210 and the inner guide edge 220 to form an integral support structure, ensuring the rigidity and stability of the slide 202.

[0023] A counting sensor 231 is fixedly installed on the surface of the connecting truss 230. When the spring moves along the slide 202, the counting sensor 231 detects and records the number of springs one by one, realizing the real-time automatic counting function.

[0024] The outer guide edge 210 has an inlet 201 and an outlet 203 on its surface. The inlet 201 is connected to the input conveyor belt 110, and the outlet 203 corresponds to the output conveyor belt 120. Both are on the same horizontal plane as the turntable 400 to ensure smooth entry and exit of the spring. A slide 202 is provided between the outer guide edge 210 and the inner guide edge 220, and this slide is located above the turntable 400. When the motor drives the turntable 400 to rotate, the spring is driven to rotate and enter the slide 202 under the action of the rough surface friction of the turntable 400, and moves forward in an orderly manner under the limiting action of the outer guide edge 210 and the inner guide edge 220.

[0025] The sorting material groups 300 are numerous and evenly distributed along the circumferential direction on the surface of the outer guide edge 210, and arranged between the feed inlet 201 and the discharge outlet 203. Each sorting material group 300 can realize the separation and discharge of a single spring, thereby realizing the function of batch sorting.

[0026] A motor is installed inside the base 100, and the motor is connected to the turntable 400 to drive the turntable 400 to rotate. The surface of the turntable 400 has a rough surface structure to increase friction, so that the spring can be stably driven forward during rotation.

[0027] In this embodiment, the bottom surface of the outer guide edge 210 is fixed to the surface of the base 100 and located on the edge surface of the turntable 400. A floating gap is provided between the bottom surface of the inner guide edge 220 and the top surface of the turntable 400. This gap avoids direct contact between the inner guide edge 220 and the turntable 400, ensuring smooth rotation of the turntable 400.

[0028] In this embodiment, a guide plate 130 is fixedly mounted on the surface of the base 100. One end of the guide plate 130 is rotatably sleeved onto the axis of the turntable 400 via a pin and fixed to the top surface of the base 100. A gap is provided between the bottom surface of the guide plate 130 and the top surface of the turntable 400. One end of the guide plate 130 is provided with a slot communicating with the inner side of the outer guide rail 210. The width of the slot is suitable for a single spring to pass through, for guiding a spring individually. This structure can prevent multiple springs from entering the slide rail 202 at the same time, ensuring the accuracy of single-row movement.

[0029] In this embodiment, the width of the slide 202 is equal to the diameter of a single spring, the inner guide edge 220 is in the shape of a semi-circular arc or a 3 / 4 circular arc, and both the outer guide edge 210 and the inner guide edge 220 are concentrically arranged with the turntable 400. This structure ensures that the spring maintains stable single-row movement within the slide 202, avoiding overlap or jamming.

[0030] In this embodiment, the surfaces of the feed inlet 201 and the discharge outlet 203 are located in the same plane as the turntable 400. The feed inlet 201 corresponds to the input conveyor belt 110, and the discharge outlet 203 corresponds to the output conveyor belt 120, ensuring smooth transmission of the spring during the feeding and discharging process.

[0031] In this embodiment, the sorting assembly 300 includes a discharge hopper 310, a lever 320, and a servo motor 330. One end of the discharge hopper 310 is fixedly connected to the surface of the outer guide rail 210, and a spring valve 311 is fixedly installed on the inner side of the discharge hopper 310. The spring valve 311 is a flexible sheet and is located in the same vertical plane as the outer guide rail 210 under normal conditions. It is used to block the port of the discharge hopper 310 and guide the spring to move along the slide rail 202. This structure can ensure that the spring remains in orderly movement within the slide rail 202 when not sorting.

[0032] In this embodiment, the paddle 320 is rotatably mounted on the surface of the discharge hopper 310, and the servo motor 330 is used to drive the paddle 320 to rotate. The rotation of the paddle 320 pushes out a single spring inside the slide 202 through the discharge hopper 310, while the spring valve 311 is elastically deflected, thereby realizing the sorting and discharge of unqualified springs.

[0033] In this embodiment, the connecting truss 230 is a portal frame structure used for connecting the outer guide edge 210 and the inner guide edge 220. Optionally, a visual recognition component is mounted on the surface of the connecting truss 230. This component is used to acquire and recognize images of passing springs, and to intelligently sort the springs based on the recognition results.

[0034] Working principle and usage process of this utility model: The input conveyor belt 110 transports the springs to be sorted to the feed inlet 201 of the outer guide edge 210. After entering, the springs rotate synchronously with the turntable 400 under the friction of the rough surface. Under the obstruction of the fixed guide plate 130, the springs slide along the curved surface of the fixed guide plate 130 and adhere to the inner side of the outer guide edge 210, following the rotation of the turntable 400. The rotation of the turntable 400 is driven by the motor built into the machine base 100. As the turntable 400 rotates, the springs enter the slide 202 between the outer guide edge 210 and the inner guide edge 220 and move in an orderly manner.

[0035] Within the slide 202, springs pass through one by one under the limiting action of the outer guide edge 210 and the inner guide edge 220. The width of the slide is equal to the diameter of a single spring, thus ensuring that the springs move forward stably in a single row. The connecting truss 230 is used to connect the outer guide edge 210 and the inner guide edge 220. A counting sensor 231 is mounted on its surface, which can count the springs one by one as they pass through, realizing an automatic statistical function.

[0036] When the spring moves with the turntable to the sorting group 300, its internal spring valve 311 normally blocks the outlet, ensuring the spring moves stably inside the slide 202. During sorting control, the servo motor 330 drives the paddle 320 to rotate, pushing the individual springs in the slide 202 out of the discharge hopper 310. At the same time, the spring valve 311 can be elastically deflected, allowing the unqualified springs to be discharged.

[0037] After selection, the springs enter the output conveyor belt 120 from the discharge port 203 of the outer guide 210 and are transported to the subsequent process. A vision recognition component is optionally installed on the surface of the connecting truss 230 to detect the springs through image recognition, thereby achieving intelligent sorting based on image information.

[0038] Through the aforementioned synergistic effect, this utility model realizes continuous operation of automatic feeding, sequential sorting, real-time counting, precise sorting, and automatic unloading of springs, and has the characteristics of high efficiency, stability, and intelligence.
