Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a feeding device with material sorting function. Background Technology

[0002] Sheet metal work is a comprehensive cold processing technology for thin metal sheets, including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming. Sheet metal processing is a technique for shaping thin sheet metal. Feeding devices are used when manually loading sheet metal.

[0003] Chinese Patent CN219620279U discloses a feeding and conveying device for sheet metal processing, relating to the technical field of sheet metal processing feeding equipment. It includes a feeding box with a feeding chamber on its rear side. Inside the feeding chamber, a lifting platform is connected via an electro-hydraulic actuator. Sheets are neatly stacked on the lifting platform. A discharge chute is located on the front of the upper part of the feeding box. A drive box is fixedly connected to the top of the feeding box. This invention uses a driving electro-hydraulic actuator to move the lifting platform and the stacked sheets on it upwards by the thickness of one sheet. A servo motor drives two feeding arms to move the top sheet forward, transferring it onto a conveyor belt. The conveyor belt then transports the sheet to a photoelectric switch position and stops, achieving automatic feeding and conveying of sheet metal processing sheets. This eliminates the need for sheet metal processing personnel to bend over and retrieve sheets, effectively reducing labor intensity and improving sheet metal processing efficiency.

[0004] In the aforementioned patent, the opening of the discharge chute allows one or two sheet metal plates of varying thicknesses to pass through. When a sheet metal plate with a relatively thick thickness appears in the same batch, it will also be transferred to the sheet metal processing platform by the operators, which will affect the entire sheet metal processing process and the quality of the final product.

[0005] The purpose of this invention is to provide a feeding device with material sorting function to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a feeding device with material sorting function, comprising: a feeding box, a discharge trough being provided at the upper front end of the feeding box, an adjusting plate vertically disposed within the discharge trough and slidably connected to the top plate of the feeding box, a threaded rod vertically rotatably connected to a fixed frame, the fixed frame being fixed to the top surface of the feeding box, a movable plate vertically sliding at the lower end of the adjusting plate, a distance sensor and a spring fixed to the adjusting plate being vertically fixed to the top surface of the movable plate, and a support located below the discharge trough being horizontally fixed to the front wall of the feeding box. The frame has a support frame with a conveyor belt installed inside. A conveying device is located on the front side of the support frame. Sensor 2 is installed on the front end of the left plate of the support frame. A baffle is vertically slidable on the front plate of the support frame. Sensor 1 is installed on the upper end of the baffle. A rack that meshes with a gear is vertically fixed at the lower rear end of the baffle. A rotating shaft that rotates with a fixed plate is horizontally fixed to the gear. The fixed plate and the bottom surface of the support frame are fixed. A drive motor is fixed to the rotating shaft. A controller that is electrically connected to the drive motor and the drive equipment of the conveyor belt is installed on the top surface of the feeding box. Sensor 1, Sensor 2 and the distance sensor are connected to the controller for signal connection.

[0007] Furthermore, the outer wall of the adjusting plate and the inner wall of the discharge chute are slidably connected. A bearing is installed in the center of the upper end of the adjusting plate. The inner wall of the bearing is fixed to the lower end of the threaded rod. A handle located above the fixing frame is fixed to the upper end of the threaded rod. The fixing frame has an inverted U-shaped cross section and is located on the outside of the adjusting plate.

[0008] Furthermore, the bottom surface of the adjusting plate is provided with a movable groove that slides with the movable plate, and both the left and right ends of the adjusting plate are provided with vertical connecting grooves that slide with the connecting block. The connecting grooves and the movable grooves are interconnected, and the side walls of the connecting block and the movable plate are fixed.

[0009] Furthermore, multiple springs are provided, evenly distributed within the movable groove. The distance sensor is located within the movable groove, and the thickness of the distance sensor is less than the distance between the inner wall of the connecting groove and the inner wall of the movable groove.

[0010] Furthermore, a strip-shaped groove is vertically formed at the lower end of the rear wall of the baffle, the rack is located in the strip-shaped groove, two fixing plates are provided, the two ends of the rotating shaft are rotatably connected to the two fixing plates respectively, the gear is located on the rear side of the rack and between the two fixing plates, the output end of the drive motor is fixed to one end of the rotating shaft, and the drive motor is fixed to the fixing plates.

[0011] Furthermore, the conveying direction of the conveying device is the same as that of the conveyor belt, and the height of the conveying device is the same as that of the conveyor belt.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0013] 1. According to the thickness of the material plate being fed, the present invention rotates the handle to drive the threaded rod to move vertically on the fixed frame. The threaded rod drives the adjusting plate through the bearing to move the movable plate to the appropriate position, and then stops rotating the handle. The electro-hydraulic actuator is activated to raise the material plate on the lifting platform. When the bottom surface of the uppermost material plate and the lower inner wall of the discharge trough are on the same horizontal plane, the electro-hydraulic actuator is closed. Then the drive device on the feeding box is activated to push the material plate with the feeding arm. After the feeding arm rotates 180 degrees, the drive device is closed. When the material plate is of the required thickness, when one end of the material plate is detected by the second sensor, the second sensor sends a signal to the controller. The controller controls the drive device on the conveyor belt to stop the conveyor belt. Then the operator can pick up the material plate on the conveyor belt for feeding. After the material plate is picked up, when the second sensor no longer detects the material plate, the second sensor transmits a signal to the controller again. The controller controls the drive device on the conveyor belt to continue the conveyor belt, thus realizing the feeding of material plates of normal thickness.

[0014] 2. In this invention, when the material plate thickness is greater than the required thickness, the feeding arm pushes the material plate so that its end corner contacts the inclined surface of the movable plate. The material plate slides on the movable plate, compressing the spring. The movable plate drives the connecting block to slide in the connecting groove. The connection between the connecting block and the connecting groove ensures that when the movable plate is at its lowest point, it avoids sagging due to its own weight and the spring after long-term use, thus ensuring that the distance between the movable plate and the discharge chute is accurate. Simultaneously, the movable plate moves the distance sensor upward, bringing it closer to the upper inner wall of the movable chute. Detecting a change in distance, the sensor transmits a signal to the controller. The controller prevents the sensor from transmitting the signal of the material plate to the controller, thus ensuring continuous operation of the conveyor belt. Simultaneously, the controller controls the drive motor to operate. The output of the drive motor drives the rotating shaft to rotate on the fixed plate. The rotating shaft drives the gear to rotate, causing the rack to move the baffle downwards, so that the upper part of the baffle is completely inserted into the support frame. The drive motor is then turned off. When the material plate passes the movable plate and is discharged from the discharge chute onto the conveyor belt, the material plate passes completely over the sensor above the baffle and falls onto the conveying device. The sensor continuously senses the material plate passing by and sends a signal to the controller. The controller controls the drive motor to restore the baffle to its original position. The operator can judge whether the material plate needs to be fed again based on whether the conveyor belt stops or the position of the baffle, thus realizing the sorting of the material plates. This solves the problem that when there are thicker material plates in the same batch, they are transferred to the sheet metal processing platform by the operator, which will affect the entire sheet metal processing process and the quality of the final product.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-7This utility model provides a technical solution: a feeding device with material sorting function, comprising: a feeding box 1, a discharge trough 2 opened at the upper front end of the feeding box 1, an adjusting plate 4 vertically disposed inside the discharge trough 2 and slidably connected to the top plate of the feeding box 1, a threaded rod 11 vertically rotatably connected to the adjusting plate 4 and threadedly connected to the fixed frame 3, the fixed frame 3 and the top surface of the feeding box 1 being fixed, the outer wall of the adjusting plate 4 and the inner wall of the discharge trough 2 being slidably connected, a bearing 12 installed in the center of the upper end of the adjusting plate 4, the inner wall of the bearing 12 and the lower end of the threaded rod 11 being fixed, a handle 10 fixed at the upper end of the threaded rod 11 located above the fixed frame 3, the fixed frame 3 having an inverted U-shaped cross section, the fixed frame 3 being located outside the adjusting plate 4, a movable plate 20 vertically sliding at the lower end of the adjusting plate 4, and the adjusting plate 4... The bottom surface has a movable groove 25 that slides with the movable plate 20. Both ends of the adjusting plate 4 have vertically extending connecting grooves 22 that slide with the connecting block 23, and these connecting grooves 22 and the movable groove 25 are interconnected. The connecting block 23 is fixed to the side wall of the movable plate 20. The connecting grooves 22 and the connecting block 23 keep the movable plate 20 at its lowest point, preventing the spring 21 from changing its elasticity and falling under its own weight. This facilitates control of the distance between the bottom surface of the discharge chute 2 and the movable plate 20. A distance sensor 24 and a spring 21 fixed to the adjusting plate 4 are vertically fixed to the top surface of the movable plate 20. The distance sensor 24 monitors the distance between the movable plate 20 and the inner wall of the movable groove 25. When the distance between them shortens, it indicates that the thickness of the material plate is relatively large. The signal is transmitted to the controller 8 for subsequent sorting. Multiple springs 21 are evenly distributed within the movable groove 25. A distance sensor 24 is located within the movable groove 25, and its thickness is less than the distance between the inner wall of the connecting groove 22 and the inner wall of the movable groove 25. A support frame 13 is horizontally fixed to the front wall of the feeding box 1, located below the discharge groove 2. A conveyor belt 5 is installed inside the support frame 13. A conveying device 9 is located on the front side of the support frame 13. The conveying direction of the conveying device 9 is the same as that of the conveyor belt 5, and the height of the conveying device 9 is the same as that of the conveyor belt 5, facilitating the conveying of the sorted material plates. A sensor 26 is installed on the front end of the left plate of the support frame 13. A baffle 6 slides vertically on the front plate of the support frame 13, and a [missing information - likely a device or component] is installed on the upper end of the baffle 6. Sensor 7, a rack 15 meshing with gear 16 is vertically fixed to the lower rear side of baffle 6, gear 16 is horizontally fixed to a rotating shaft 17 that rotates with fixed plate 18, fixed plate 18 and the bottom surface of support frame 13 are fixed, rotating shaft 17 is fixed to drive motor 19, a strip groove 14 is vertically opened at the lower rear wall of baffle 6, rack 15 is located in strip groove 14, two fixed plates 18 are provided, the two ends of rotating shaft 17 are rotatably connected to the two fixed plates 18 respectively, gear 16 is located behind rack 15 and between the two fixed plates 18, the output end of drive motor 19 is fixed to one end of rotating shaft 17, drive motor 19 is fixed to fixed plate 18, controller 8 electrically connected to drive motor 19 and drive equipment of conveyor belt 5 is installed on the top surface of loading box 1, and the controller 8 is electrically connected to drive motor 19 and drive equipment of conveyor belt 5.Sensor 7, Sensor 26, and Distance Sensor 24 are connected to Controller 8. Distance Sensor 24 can be an infrared distance sensor, such as GP2Y0A21YK0F. This type of sensor uses infrared light to measure distance and is commonly used for precise measurements over short distances. Controller 8 can be an Arduino controller used in conjunction with the infrared distance sensor. The Arduino controller can also control motors; it can control the motor's start, stop, and speed via its digital or analog pins, enabling complex motion control. Sensor 26 is primarily used for object detection and can be an inductive proximity sensor. Inductive proximity sensors are non-contact devices that detect the disruption of electromagnetic fields by metallic objects. They are widely used in automation and process equipment. The inductive proximity sensor transmits signals to the Arduino controller. Sensor 7 is mainly for continuously sensing objects and transmitting signals to Controller 8. Sensor 7 can be an infrared sensor or an optical sensor. Both infrared and optical sensors can transmit signals to the Arduino controller. The Arduino controller, through its digital or analog pins, can receive signals from the infrared and optical sensors and perform further processing and control.

[0026] Working principle of this utility model:

[0027] Refer to the instruction manual appendix Figure 1-7 Based on the thickness of the material plate being fed, rotating handle 10 drives threaded rod 11 to rotate. Due to the threaded connection between threaded rod 11 and fixed frame 3, threaded rod 11 moves vertically. The lower end of threaded rod 11 rotates on bearing 12, and threaded rod 11 drives adjusting plate 4 to slide vertically on feeding box 1 through bearing 12. In turn, adjusting plate 4 moves movable plate 20 vertically to a suitable position, that is, the distance between the bottom surface of movable plate 20 and the lower inner wall of discharge trough 2 is equal to the thickness of the material plate. Then, stop rotating handle 10; start the electro-hydraulic actuator in feeding box 1 to raise the material plate on the lifting platform. When the bottom surface of the uppermost material plate and the lower inner wall of discharge trough 2 are on the same horizontal plane, close the electro-hydraulic actuator, and then start the drive device on feeding box 1 to push the material plate with the feeding arm. After the feeding arm rotates 180 degrees, the drive device is closed.

[0028] When the material plate is of the required thickness, that is, the thickness of the material plate is just right to be discharged from the discharge chute 2 and fall onto the conveyor belt 5, when one end of the material plate is detected by sensor 26, sensor 26 sends a signal to controller 8. Controller 8 controls the drive device on conveyor belt 5 to stop conveying. Then the operator can pick up the material plate on conveyor belt 5 for loading. After the material plate is picked up, when sensor 26 no longer detects the material plate, sensor 26 transmits a signal to controller 8 again. Controller 8 controls the drive device on conveyor belt 5 to continue conveying.

[0029] When the material plate thickness is greater than the required thickness, the feeding arm pushes the material plate so that its end corner contacts the inclined surface of the movable plate 20. The material plate slides on the movable plate 20 and within the movable groove 25. The movable plate 20 compresses the spring 21, causing the connecting block 23 to slide within the connecting groove 22. The connection between the connecting block 23 and the connecting groove 22 prevents the movable plate 20 from sagging due to its own weight and the long-term use of the spring 21 when it is at its lowest point. This ensures that the distance between the movable plate 20 and the discharge chute 2 is accurate. Simultaneously, the movable plate 20 moves the distance sensor 24 upward, causing it to move closer to the upper inner wall of the movable groove 25. Upon detecting a change in distance, the sensor transmits a signal to the control unit. The controller 8 prevents sensor 26 from transmitting a signal indicating the material plate is detected, thus ensuring continuous operation of the conveyor belt 5. Simultaneously, the controller 8 controls the drive motor 19, whose output drives shaft 17 to rotate on the fixed plate 18. Shaft 17 drives gear 16, causing rack 15 to move baffle 6 downwards until its upper end is fully inside the support frame 13. The drive motor 19 then shuts off. When the material plate passes the movable plate 20 and is discharged from the discharge chute 2 onto the conveyor belt 5, it passes completely over sensor 7 above baffle 6 and lands on the conveyor device 9. Sensor 7 continuously senses the material plate's passage and transmits a signal to the controller 8. The controller 8 then controls the drive motor 19 to restore baffle 6 to its original position.

[0030] Operators can determine whether a material plate needs to be fed again based on whether the conveyor belt 5 has stopped or the position of the baffle, thus achieving the sorting of material plates. This solves the problem that when a thicker material plate appears in the same batch, it will be transferred to the sheet metal processing platform by the operators, which will affect the entire sheet metal processing process and the quality of the final product.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
