Description

Technical Field

[0001] The utility model relates to the technical field of material sorting, in particular to a teaching device for material sorting. Background Art

[0002] Material sorting systems are part of the industrial automation sector, primarily used to improve production efficiency, reduce labor costs, and ensure accurate and consistent sorting. Historically, this type of sorting technology was first used in mining and agriculture to sort materials of varying sizes and types. However, with the rapid advancement of electronics and sensor technologies, modern material sorting has far surpassed simple manual or mechanical sorting. Previous sorting systems relied heavily on mechanical systems (e.g., screens, vibrating conveyor belts, etc.), which primarily distinguished materials based on physical characteristics (e.g., size and weight). While simple, these systems were inefficient and required significant manual intervention. With the maturity of detection devices such as photoelectric sensors and color sensors, sorting systems have begun to rely on visual, color, and light intensity characteristics to automatically identify materials. This phase marked the transition from simple physical sorting to intelligent sorting based on data and information. Programmable logic controllers (PLCs) have gradually become the core of sorting systems, responsible for real-time control of actuators such as conveyor belts and robotic arms, and for performing logical judgments based on sensor data. This makes sorting systems more flexible and programmable, adapting to diverse production needs. However, many people don’t know much about the sorting system with PLC as the core. Therefore, we need to provide a material sorting teaching device to help them understand the basic distance, movement and structure of the sorting system.

[0003] At present, the PLC sorting system in the field of industrial automation is directly taught. However, due to the large size of the PLC sorting system in the actual industrial automation field, it is not easy to carry. In addition, due to actual needs, these PLC sorting systems often have complex actions to execute and a single action takes a long time to complete. Directly using them for teaching will affect the teaching effect. Utility Model Content

[0004] The technical problem to be solved by the present invention is: in order to solve the technical problem that the use of PLC sorting systems in the existing industrial automation field for teaching will affect the teaching effect, the present invention provides a teaching device for material sorting, and by improving the structure of the teaching device, the teaching effect of the PLC sorting system can be improved.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a teaching device for material sorting, comprising: a frame, a first drive unit, a second drive unit, a plurality of silos and an operating table, the frame comprising: a horizontal plate and a vertical plate, the horizontal plate is connected to the vertical plate, a PLC is installed on the side of the vertical plate close to the first drive unit, and the first drive unit is located on the rear side of the horizontal plate, the second drive unit, a plurality of silos and an operating table are all installed on the horizontal plate, the second drive unit is located on the right side of the horizontal plate, the silo is located on the left side of the second drive unit and on the side close to the first drive unit, and the operating table is located at the left front corner of the horizontal plate; wherein: the first drive unit is used to drive the material to move along the Y-axis and the Z-axis to transport the material from the middle position to the silo, and the PLC moves along the X-axis to transport the material from the upper material position to the middle position.

[0006] Therefore, by arranging the first drive unit, PLC, second drive unit, silo and operating platform on the frame, and using the teaching device formed by this layout for teaching, compared with the teaching method of directly teaching the PLC sorting system in the industrial automation field, this method has a simple structure and is easy to operate. It can make full use of the space of the frame, shorten the volume of the entire teaching device, and thus facilitate the transportation of the entire teaching device. At the same time, the teaching device has simple actions and a short time to complete a single action, which can shorten the teaching time of the PLC sorting system and thus improve the teaching effect of the PLC sorting system.

The Y-axis drive unit is connected to the horizontal plate, the drive end of the Y-axis drive unit is connected to the Z-axis drive unit, and the suction member is installed at the drive end of the Y-axis drive unit. The suction member is connected to the PLC. Thus, the Y-axis drive unit can drive the material to be transported along the Y-axis direction, the Z-axis drive unit can drive the material to be transported along the Z-axis direction, and the suction member can absorb the material, so that the Y-axis drive unit and the Z-axis drive unit can act on the material to drive the material to move.

[0009] Furthermore, the Y-axis drive unit includes: a support frame, a first drive member, a screw, and a first slider; the support frame is connected to the horizontal plate; the first drive member is connected to the support frame; one end of the screw is connected to the drive end of the first drive member; the other end of the screw is rotatably connected to the support frame; the screw passes through the first slider and is threadedly connected to the first slider; the Z-axis drive unit is connected to the first slider; and the first drive member is connected to the PLC. Thus, the first drive member is activated and the screw is controlled to rotate by the first drive member, so that the first slider moves along the axial direction of the screw, ultimately realizing the conveying of materials along the Y-axis direction.

[0010] Furthermore, the Z-axis drive unit includes a second drive member, a gear belt assembly, and a second slider. The second drive member is connected to the first slider, the input end of the gear belt assembly is connected to the drive end of the second drive member, and the output end of the gear belt assembly is connected to the second slider. The second slider is connected to the adsorption member. The second drive member is connected to the PLC. Thus, when the second drive member is activated, it controls the movement of the gear belt assembly, causing the second slider to move in conjunction with the movement of the gear belt assembly, ultimately achieving material conveyance along the Z-axis.

[0011] The system further includes a color sensor installed in the middle of the second drive unit, configured to identify the color of the material; wherein the color sensor is connected to the PLC. Thus, the color sensor is configured to identify the color of the material and distinguish the materials based on their color to achieve material sorting.

[0012] Furthermore, the operating console is provided with a plurality of operating buttons, wherein the operating buttons are connected to the PLC, so that the operation of the entire teaching device can be controlled through the operating buttons.

[0013] Furthermore, the operating table is provided with a plurality of indicator lights, wherein the indicator lights are connected to the PLC. Thus, the operating status of the entire teaching device can be judged based on the color of the indicator lights, thereby determining the progress of the material sorting.

[0014] Furthermore, the device further comprises: two handles, which are mounted on the horizontal plate and are located on the left and right sides of the horizontal plate, respectively. Thus, the handles can facilitate the transportation of the entire teaching device.

At the same time, the teaching device has simple actions and a short time to complete a single action, which can shorten the teaching time of the PLC sorting system and thus improve the teaching effect of the PLC sorting system.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0029] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0030] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0031] like Figures 1 to 8The figure shows the optimal embodiment of the present invention. The material sorting teaching device of this embodiment includes: a frame 1, a first drive unit 2, a second drive unit 4, a plurality of silos 5 and an operating table 6. The frame 1 includes: a horizontal plate 101 and a vertical plate 102. The horizontal plate 101 is connected to the vertical plate 102. The PLC3 is installed on the side of the vertical plate 102 close to the first drive unit 2, and the first drive unit 2 is located on the rear side of the horizontal plate 101. The second drive unit 4, a plurality of silos 5 and an operating table 6 are all installed on the horizontal plate 101. The second drive unit 4 is located on the right side of the horizontal plate 101, and the silo 5 is located on the left side of the second drive unit 4 and on the side close to the first drive unit 2. The operating table 6 is located at the left front corner of the horizontal plate 101; wherein: the first drive unit 2 is used to drive the material 7 to move along the Y-axis and the Z-axis to transport the material 7 from the middle position to the silo 5, and the PLC3 moves along the X-axis to transport the material 7 from the upper position to the middle position. Therefore, by arranging the first drive unit 2, PLC3, the second drive unit 4, the silo 5 and the operating platform on the frame 1, and using the teaching device formed by this layout for teaching, compared with the teaching method of directly teaching the PLC3 sorting system in the industrial automation field, this method has a simple structure and is easy to operate. It can make full use of the space of the frame 1, shorten the volume of the entire teaching device, and thus facilitate the transportation of the entire teaching device. At the same time, the teaching device has simple actions and a short time to complete a single action, which can shorten the teaching time of the PLC3 sorting system and thus improve the teaching effect of the PLC3 sorting system.

[0032] In other words, the PLC3 sorting system used in the industrial automation field has inconsistent product sorting locations (good products after sorting are placed in area A, bad products are placed in area B, and areas AB are often not together), and the sorting execution process is complicated (sorting is often performed after material 7 is processed). Directly replacing it with teaching will take a long time (the purpose of teaching is to clearly demonstrate its functions rather than actual application).

[0033] It should be noted that improving the teaching effect is reflected in two aspects. On the one hand, the design layout of this solution can shorten the volume of the entire teaching device and facilitate transportation. On the other hand, it simplifies the execution process of complex sorting actions and shortens the teaching time for sorting material 7.

[0034] In this embodiment, the plurality of silos 5 are sequentially distributed along the Y-axis direction. Thus, the sequentially arranged silos 5 can further reduce the volume of the entire teaching device.

[0035] In this embodiment, the first driving part 2 includes: a Y-axis driving unit 201, a Z-axis driving unit 202 and an adsorption member 203, the Y-axis driving unit 201 is connected to the horizontal plate 101, the driving end of the Y-axis driving unit 201 is connected to the Z-axis driving unit 202, and the adsorption member 203 is installed at the driving end of the Y-axis driving unit 201; the Y-axis driving unit 201 includes: a support frame 2011, a first driving member 2012, a screw rod 2013 and a first slider 2014, the support frame 2011 is connected to the horizontal plate 101, the first driving member 2012 is connected to the support frame 2011, one end of the screw rod 2013 is connected to the driving end of the first driving member 2012 The ends are connected, the other end of the screw rod 2013 is rotatably connected to the support frame 2011, the screw rod 2013 passes through the first slider 2014, and is threadedly connected to the first slider 2014; the Z-axis drive unit 202 is connected to the first slider 2014; the Z-axis drive unit 202 includes: a second drive member 2021, a gear belt group 2022 and a second slider 2023, the second drive member 2021 is connected to the first slider 2014, the input end of the gear belt group 2022 is connected to the drive end of the second drive member 2021, and the output end of the gear belt group 2022 is connected to the second slider 2023; the second slider 2023 is connected to the adsorption member 203. Thus, the material 7 can be driven to be transported along the Y-axis direction through the Y-axis drive unit 201, the material 7 can be driven to be transported along the Z-axis direction through the Z-axis drive unit 202, and the material 7 can be adsorbed by the adsorption member 203, so that the Y-axis drive unit 201 and the Z-axis drive unit 202 can act on the material 7 to drive the material 7 to move; the first drive member 2012 is started, and the first drive member 2012 controls the rotation of the screw rod 2013, so that the first slider 2014 moves along the axial direction of the screw rod 2013, and finally the material 7 is transported along the Y-axis direction; the second drive member 2021 is started, and the gear belt group 2022 is controlled to move through the second drive member 2021, so that the second slider 2023 moves with the movement of the gear belt group 2022, and finally the material 7 is transported along the Z-axis direction.

[0036] Specifically, the gear belt group 2022 includes: a driving wheel, a driven wheel and a belt. The driving end of the second driving member 2021 is connected to the driving wheel, and the driving wheel and the driven wheel are both connected to the belt. The second slider 2023 is installed on the belt. The second driving member 2021 is started, and the driving wheel is driven to rotate by the second driving member 2021, so that the belt rotates, and finally drives the second slider 2023 to move.

[0037] For example, the second driving part 4 uses a conveying track, the first driving part 2012 and the second driving part 2021 both use motors, and the adsorption part 203 uses an electromagnet (the material 7 is made of magnetic material. When power is applied, the electromagnet can adsorb the material 7. When power is not applied, the electromagnet cannot adsorb the material 7, and the material 7 is free from the restraint of the adsorption part 203).

[0038] This embodiment further includes a color sensor 8, which is mounted in the middle of the second drive unit 4 and is used to identify the color of the material 7. The color sensor 8 is connected to the PLC 3. Thus, the operating status of the entire teaching device can be determined based on the color of the indicator light 602, thereby determining the progress of the sorting of the material 7.

[0039] In this embodiment, the operating console 6 is provided with a plurality of operating buttons 601 and a plurality of indicator lights 602. Thus, the operation of the entire teaching device can be controlled by the operating buttons 601; the operating status of the entire teaching device can be determined by the color of the indicator lights 602, thereby determining the progress of the sorting of the material 7.

[0040] For example, the operation button 601 includes: a start / stop function button, a confirmation function button, and a sorting requirement function button (taking color sorting material 7 as an example, the red, blue, and yellow buttons mean: the color sorting requirement is to place the red material 7 in the first silo 5, the blue material 7 in the second silo 5, and the yellow material 7 in the third silo 5).

[0041] For example, if the indicator light 602 is green, it indicates that the entire system is running, and if it is red, it indicates that the entire system has a fault. The on and off colors of the indicator light 602 can be set according to the operating mode.

[0042] In this embodiment, the device further comprises two handles 9 , which are mounted on the horizontal plate 101 and are respectively located on the left and right sides of the horizontal plate 101 . Thus, the handles 9 can facilitate the transportation of the entire teaching device.

[0043] This embodiment further includes a support rod 10, with both ends of the support rod 10 connected to a horizontal plate 101 and a vertical plate 102, respectively. The horizontal plate 101, the vertical plate 102, and the support rod 10 are arranged in a triangle. Thus, the triangular support structure between the horizontal plate 101, the vertical plate 102, and the support rod 10 can improve the structural strength of the entire teaching device.

[0044] In this embodiment, the first driving member 2012, the second driving member 2021, the second driving unit 4, the operating button 601, the indicator light 602, and the color sensor 8 are all connected to the PLC 3. Specifically, the PLC 3 can control the start and stop of the first driving member 2012, the second driving member 2021, the second driving unit 4, and the indicator light 602 based on the instructions of the operating button 601 and the detection results of the color sensor 8, thereby controlling the operating state of the entire teaching device.

[0045] The teaching process of sorting materials 7 of the present invention (taking the sorting of materials 7 of three colors, red, yellow, and blue, as an example) is as follows: first, three silos 5 are set up in sequence from left to right (the three silos 5 are respectively recorded as silo A 5 (for placing screened red materials 7), silo B 5 (for placing screened yellow materials 7), and silo C 5 (for placing screened blue materials 7));

[0046] Then, the operation button 601 is pressed, and the material 7 to be sorted is gradually placed at the loading position of the second drive unit 4. Through the cooperation of the first drive unit 2, the second drive unit 4, and the color sensor 8 (if the color sensor 8 detects that the color of the material 7 is red, it is sorted to the position of the A silo 5; if the color sensor 8 detects that the color of the material 7 is yellow, it is sorted to the position of the B silo 5; if the color sensor 8 detects that the color of the material 7 is blue, it is sorted to the position of the C silo 5), the screening of materials 7 of different colors is completed.

[0047] In summary, the utility model arranges the first drive unit 2, PLC3, the second drive unit 4, the silo 5 and the operating platform on the frame 1, and uses the teaching device formed by this layout to perform teaching. Compared with the teaching method of directly teaching the PLC3 sorting system in the industrial automation field, this method has a simple structure and is easy to operate. It can make full use of the space of the frame 1, shorten the volume of the entire teaching device, and thus facilitate the transportation of the entire teaching device. At the same time, the teaching device has simple actions and a short time to complete a single action, which can shorten the teaching time of the PLC3 sorting system and thus improve the teaching effect of the PLC3 sorting system.

[0048] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of this utility model. The technical scope of this utility model is not limited to the content of the specification and must be determined according to the scope of the claims.
