Description

Technical Field

[0001] This utility model relates to the technical field of bar stock processing, and in particular to the technical field of a bar stock discharge device. Background Technology

[0002] Bar stock generally refers to straight strip-shaped processed materials with simple cross-sectional shapes such as circles, squares, and hexagons. Bar stock is usually one of the most common materials in machining, such as steel bars, aluminum bars, wooden bars, and plastic bars. Bar stock usually needs to be straightened, chamfered, shot blasted, flawed, and ground to improve the overall performance of the bar stock and facilitate subsequent bar stock cutting and other processing steps.

[0003] Currently, bar stock is typically handled in a semi-automatic manner using manual labor and conveyors during processing. Specifically, workers manually remove the bar stock from the silo and place it onto the conveyor for transport. Obviously, this method not only results in high labor intensity for workers, inconvenience, and low turnover efficiency, but also poses a safety hazard of human injury due to manual handling of the bar stock.

[0004] To address the problems raised in the background art, for example, application number CN202023275472.8 discloses a bar stock feeding device, including a frame with an inverted cone-shaped hopper embedded in the frame. The hopper has a vibrator on its side wall and a discharge port at its bottom. A conveyor belt is horizontally mounted outside the frame below the discharge port. A horizontally arranged and rotatable tilting shaft is rotatably mounted below the hopper on the frame. A guide plate is fitted onto the tilting shaft between the discharge port and the conveyor belt. Through the cooperation of the vibrator, hopper, tilting guide plate, and conveyor belt, the bar stock in the hopper automatically falls from the discharge port to the guide plate under the action of the vibrator, then slides from the guide plate to the conveyor belt under its own gravity, and is finally transported to the processing position by the conveyor belt. This achieves the technical effect of quickly and efficiently transferring the bar stock in the hopper to the processing position. However, this device still has the following drawbacks:

[0005] Although the device transports the bar stock to the processing position via a conveyor belt, the lack of an infrared sensor and a pusher structure on the conveyor belt makes it impossible to accurately transport the bar stock to the designated position, which can easily lead to errors in processing accuracy. Summary of the Invention

[0006] The purpose of this invention is to solve the problems in the prior art by proposing a bar stock feeding device that can accurately feed the bar stock to a designated position, thereby ensuring the accuracy of subsequent processing.

[0007] To achieve the above objectives, this utility model proposes a bar stock discharging device, comprising a support plate, support feet, a conveyor sprocket, a conveyor chain, a baffle, an infrared sensor, a fixed plate, a pushing mechanism, a first cylinder, a first piston rod, and a pushing plate. The support plates are symmetrically arranged, and each support plate has several support feet on its lower end face. Two conveyor sprockets are rotatably arranged between the support plates, located at the front and rear ends of the support plates respectively. A conveyor chain is wound around both conveyor sprockets. A baffle is provided above each support plate, and an infrared sensor for sensing bar stock is installed on the side wall of one of the baffles. A fixed plate is installed on the side wall of the support plate, and a pushing mechanism is provided above the fixed plate. The pushing mechanism includes a first cylinder, a first piston rod, and a pushing plate. The driving end of the first cylinder is connected to the first piston rod, and the end of the first piston rod is connected to the pushing plate. The pushing plate is used to push the bar stock out of the conveyor chain.

[0008] Preferably, a drive motor is mounted on the side wall of one of the support plates, and the output end of the drive motor passes through the side wall of the support plate and is connected to one of the transmission sprockets.

[0009] Preferably, the infrared sensor is electrically connected to the first cylinder via a PLC control system.

[0010] Preferably, one of the support plates is equipped with a discharge plate, which is slightly inclined downwards and corresponds to the pusher plate.

[0011] Preferably, a concave bracket is mounted on both support plates, a second cylinder is mounted on the concave bracket, the drive end of the second cylinder passes through the lower part of the concave bracket and is connected to a second piston rod, the end of the second piston rod is connected to a cleaning plate, and a cleaning brush is adhered to the lower end face of the cleaning plate.

[0012] Preferably, the cleaning brush is located directly above the conveyor chain.

[0013] The beneficial effects of this utility model are:

[0014] This invention, through the combined action of an infrared sensor and a pushing mechanism, enables precise feeding of bar stock to a designated position. First, the drive motor is connected to an external power source, then started. The drive motor drives the conveyor sprocket to rotate, which in turn drives the conveyor chain, causing another conveyor sprocket to rotate synchronously. This then begins the bar stock feeding process. When the bar stock passes the sensing end of the infrared sensor, the sensor receives a signal and sends it to the PLC control system. After processing for several seconds, the PLC control system controls the first cylinder to extend and retract its piston rod, thereby extending the pushing plate forward and pushing the bar stock from the conveyor chain onto the discharge plate, from which it slides to the designated position. This improves the accuracy of bar stock feeding, ensures processing quality, and avoids errors in subsequent processing. It solves the problem of inaccurate bar stock feeding due to the lack of an infrared sensor and pushing mechanism. Attached Figure Description

Detailed Implementation

[0020] See Figures 1 to 4This utility model discloses a bar stock discharging device, comprising a support plate 1, support feet 2, conveyor sprockets 3, conveyor chain 4, baffle 5, infrared sensor 6, fixing plate 7, pushing mechanism 8, first cylinder 81, first piston rod 82, and pushing plate 83. The support plates 1 are symmetrically arranged, and each support plate 1 has several support feet 2 on its lower end face. Two conveyor sprockets 3 are rotatably arranged between the support plates 1, located at the front and rear ends of the support plates 1 respectively. A conveyor chain 4 is wound around both conveyor sprockets 3. Each support plate 1 has a baffle 5 above it, and an infrared sensor 6 for sensing bar stock is installed on the side wall of one of the baffles 5. A fixing plate 7 is installed on the side wall of the support plate 1, and a pushing mechanism 8 is located above the fixing plate 7. The pushing mechanism 8 includes a first cylinder 81, a first piston rod 82, and a pushing plate 83. The first cylinder 81 is driven... A first piston rod 82 is connected to the end of the conveyor chain 4, and a pusher plate 83 is connected to the end of the first piston rod 82. The pusher plate 83 is used to push the bar material on the conveyor chain 4 out. When the bar material passes the sensing end of the infrared sensor 6, the infrared sensor 6 receives a signal and sends the signal to the PLC control system. After processing for several seconds, the PLC control system controls the first cylinder 81 to drive the first piston rod 82 to extend and retract, thereby driving the pusher plate 83 to extend forward and push the bar material on the conveyor chain 4 onto the discharge plate 10, and then slide it off the discharge plate 10 to the designated position. At the same time, since the PLC control system needs to process for several seconds before it can control the first cylinder 81 to operate, the bar material can move to the front of the pusher plate 83 under the conveyor chain 4. After processing, the PLC control system can accurately control the first cylinder 81 to push the bar material onto the discharge plate 10, thereby improving the conveying efficiency.

[0021] See Figure 2 One of the support plates 1 has a drive motor 9 mounted on its side wall. The output end of the drive motor 9 passes through the side wall of the support plate 1 and is connected to one of the transmission sprockets 3. In this application, the drive motor 9 is electrically connected to an external control power supply via a wire. At the same time, the control power supply can also control the speed of the drive motor 9.

[0022] See Figures 1 to 2 The infrared sensor 6 is electrically connected to the first cylinder 81 through a PLC control system. It should be noted that the PLC control system diagram is not shown in this application.

[0023] See Figure 2 One of the support plates 1 is equipped with a discharge plate 10, which is set slightly downward and corresponds to the pusher plate 83, so that after the pusher plate 83 pushes the bar, the bar can fall accurately onto the discharge plate 10, thereby improving the processing quality.

[0024] See Figure 3 A concave bracket 11 is mounted on both support plates 1. A second cylinder 12 is mounted on the concave bracket 11. The driving end of the second cylinder 12 passes through the lower part of the concave bracket 11 and is connected to a second piston rod 13. The end of the second piston rod 13 is connected to a cleaning plate 14. A cleaning brush 15 is attached to the lower end face of the cleaning plate 14. The cleaning brush 15 is located directly above the conveyor chain 4. Since there are some debris on the surface of the bar stock after processing, in order not to affect the subsequent processing quality, this application drives the second piston rod 13 to descend through the second cylinder 12. The second piston rod 13 drives the cleaning plate 14 to descend, so that the cleaning brush 15 below the cleaning plate 14 descends synchronously. When the bar stock passes the cleaning brush 15, the cleaning brush 15 can perform preliminary cleaning on the surface of the bar stock, so that the cleaned debris can pass through the gap on the conveyor chain 4 and fall into the chip collection frame below (not shown in the figure), thereby avoiding excessive impurities on the bar stock that would affect the subsequent processing effect.

[0025] The working process of this utility model:

[0026] In operation, the bar stock feeding device of this utility model drives the transmission sprocket 3 to rotate via the drive motor 9, which in turn drives the transmission chain 4 to rotate, causing another transmission sprocket 3 to rotate synchronously. This then drives the bar stock to begin feeding. When the bar stock passes the sensing end of the infrared sensor 6, the infrared sensor 6 receives a signal and sends the signal to the PLC control system. After processing for several seconds, the PLC control system controls the first cylinder 81 to drive the first piston rod 82 to extend and retract, thereby causing the pusher plate 83 to extend forward and push the bar stock on the transmission chain 4 onto the feeding plate 10, and then slide it off the feeding plate 10 to the designated position. This improves the feeding accuracy of the bar stock and ensures the processing quality.

[0027] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0028] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
