Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a feeding device. Background Technology

[0002] In machining, bulk workpiece transfer is typically handled using material frames. Finished workpieces are placed sequentially into the frame, and once full, the frame is moved by workers. Manual loading and unloading by workers allows for precise control over the force and flatness applied, preventing damage. However, as companies demand higher production efficiency, automated loading and unloading using gantry robots or articulated robots has become commonplace. After processing, these robots grip the workpieces and place them into the material frame.

[0003] The workpiece frame has a certain depth, and both gantry robots and articulated robots directly drop the workpieces into it. This results in the workpieces being subjected to significant impact upon falling into the frame, making them prone to damage, especially the first few workpieces. Besides the gantry robot or articulated robot directly dropping the workpieces into the frame, another method is to use a conveyor belt that connects to the frame. The gantry robot or articulated robot places the processed workpieces onto the conveyor belt, which then drops them into the frame. However, this method also results in the workpieces being subjected to impact. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a feeding device that solves the problem of easy collisions during workpiece feeding.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A feeding device includes a support and a material frame located inside the support. The support has a horizontally arranged cage-like body at its top and a drive motor capable of rotating the cage-like body. A chute is provided on the support. The chute has a first section arranged vertically inclined and a second section connected to the lower end of the first section and arranged horizontally. The second section extends into the cage-like body, and its bottom surface is inclined. A notch is provided on one side of the second section at its lowest point. The cage-like body has several circumferentially distributed feeding ports, one of which has a flexible receiving plate fixed to its side. The lower end of the flexible receiving plate extends to the bottom of the material frame.

[0007] In use, the material frame is empty, and the lower end of the flexible receiving plate is located inside the bottom of the material frame, at which point the flexible receiving plate is in a fully released state. A robotic arm picks up the processed workpiece and places it into the chute. The workpiece slides down the first section of the chute into the second section. Since the second section of the chute is horizontally oriented, sharing the same orientation as the cage-like structure, and its bottom surface is inclined, a notch is provided on one side at its lowest point. This allows the workpiece sliding into the second section to slide out of the notch using the bottom surface of the second section. The cage-like structure has several circumferentially distributed drop ports, one of which has a flexible receiving plate fixed to its side. The lower end of the flexible receiving plate extends to the bottom of the material frame. Thus, the workpiece sliding out of the notch will, under its own weight, fall down through the drop port below it onto the flexible receiving plate, and finally fall into the material frame along the flexible receiving plate.

[0008] This feeding device, through the arrangement of a chute, a cage-like structure, and a flexible receiving plate, allows the workpiece to slide naturally into the material frame. The switching between the first and second sections of the chute provides an initial buffer for the workpiece, while the flexible receiving plate provides a second buffer. Compared to a robotic arm directly throwing the workpiece into the material frame, this significantly reduces the impact force and effectively prevents the workpiece from bumping or colliding. Furthermore, the cage is driven by a drive motor. As workpieces continuously fall into the material frame, they accumulate within the frame. Once the workpieces reach a certain height, the drive motor can be rotated at an angle to roll the flexible receiving plate upwards a certain height. This ensures that the flexible receiving plate is not pressed down by the accumulated workpieces. The frequency of winding the flexible receiving plate can be determined based on the number of workpieces placed in the frame. For example, after placing several large workpieces, the flexible receiving plate can be rolled upwards once, or after placing several small workpieces, the flexible receiving plate can be rolled upwards once. The number of workpieces placed can be counted by setting sensors on the robotic arm. The robotic arm counts once each time it picks up a workpiece. When the frame is full of workpieces, the flexible receiving plate is essentially detached from the frame, thus preventing interference between the flexible receiving plate and the handling of the frame.

[0009] In the above-mentioned feeding device, the cage-like body includes a circular plate, an annular plate opposite to the circular plate, and several connecting rods fixedly connected between the circular plate and the annular plate. The above-mentioned material drop opening is formed between two adjacent connecting rods. The upper end of the flexible receiving plate is fixedly connected to one of the connecting rods, and the second section passes through the annular plate.

[0010] After the circular plate, the annular plate, and several connecting rods are fixedly connected to form a cage-like body, the central hole of the annular plate provides a position for the second section to extend into the cage-like body, and the gap between two adjacent connecting rods naturally forms the material discharge port.

[0011] In one of the above-mentioned feeding devices, the connecting rod connected to the flexible receiving plate is flat and the flexible receiving plate is in contact with one side plane of the connecting rod and fixedly connected by fasteners. The remaining connecting rod is a round rod.

[0012] The connecting rod that connects to the flexible receiving plate is designed to be flat, with a flat side, which allows the flexible receiving plate to fit snugly against the connecting rod and provides a position for secure installation of the fastener.

[0013] In the aforementioned feeding device, all connecting rods except the one connected to the flexible receiving plate are fitted with rubber sleeves, and all connecting rods are fixedly connected to the annular plate by screws.

[0014] Covering the connecting rods, except for the one connected to the flexible receiving plate, with rubber sleeves can protect the workpiece from impacts within the cage. Fixing the connecting rods to the annular plate with screws allows workers to remove the annular plate by unscrewing the screws to replace the worn rubber sleeves.

[0015] In one of the above-mentioned feeding devices, the end of the connecting rod connected to the flexible receiving plate has an abutment step, and the inner edge of the annular plate abuts against the abutment step.

[0016] The inner edge of the annular plate abuts against the abutment step, so that the connecting rod connected to the flexible receiving plate can be circumferentially fixed with the annular plate, that is, there will be no rotation, ensuring that the flexible receiving plate can be smoothly wound as the cage rotates.

[0017] In the aforementioned feeding device, the support includes a frame composed of vertical and horizontal tubes and a top plate fixedly connected to the top of the frame. The top plate is also fixedly connected to a bearing seat and a mounting base. The bearing seat has a rotating shaft along the axial direction of the cage-like body. The circular plate of the cage-like body is fixedly connected to the rotating shaft. The drive motor is fixedly connected to the mounting base. The output shaft of the drive motor and the rotating shaft transmit power through a chain mechanism. The top plate has a clearance groove. The cage-like body passes through the clearance groove. The bottom of the chute is integrally fixedly connected to a base, which is fixedly connected to the top plate.

[0018] The support includes a frame composed of vertical and horizontal tubes and a top plate fixedly connected to the top of the frame. This places the material frame within the lower part of the frame, allowing it to move freely out of the support, facilitating the operation of the frame after it is filled with workpieces. The top plate provides a mounting location for the chute, the cage-like structure, and the drive mechanism for rotating the cage-like structure.

[0019] In one of the aforementioned feeding devices, the top plate is also fixedly connected to a protective cover, with the cage-like body located inside the cover, and the upper end of the first section of the chute extending outside the cover. The protective cover serves as a protective measure on-site.

[0020] In one of the above-mentioned feeding devices, the flexible receiving plate is a polyurethane plate.

[0021] Compared with existing technologies, this feeding device has the following advantages:

[0022] 1. By setting up the chute, cage-like body and flexible receiving plate, the robot arm can place the processed workpiece into the chute and then let it slide naturally into the material frame. The switching between the first and second sections of the chute can provide the first buffer for the workpiece, and the flexible receiving plate can provide the second buffer. Compared with the robot arm directly throwing the workpiece into the material frame, the impact force is greatly reduced, thus effectively avoiding the collision of the workpiece.

[0023] 2. The cage is driven by a drive motor. As the workpieces fall into the material frame, they will accumulate in the frame. After the workpieces accumulate to a certain height, the drive motor can be controlled to rotate at an angle so that the flexible receiving plate is rolled upwards to a certain height. This ensures that the flexible receiving plate will not be pressed down by the accumulated workpieces. Attached Figure Description

[0035] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a feeding device includes a support 1 and a material frame 2 located inside the support 1. The support 1 includes a frame 1a consisting of four vertical tubes and several horizontal tubes fixedly connected between the upper ends of the four vertical tubes, and a top plate 1b fixedly connected to the top of the frame 1a. The top of the support 1 is provided with a horizontally arranged cage 3 and a drive motor 4 capable of driving the cage 3 to rotate around its own axis. The top plate 1b is fixedly connected to a bearing seat 5 and a mounting seat 6. The bearing seat 5 has a rotating shaft 7 along the axial direction of the cage-like body 3. One end of the cage-like body 3 is open, and the other end of the cage-like body 3 is fixedly connected to the rotating shaft 7. The drive motor 4 is fixedly connected to the mounting seat 6. The output shaft of the drive motor 4 and the rotating shaft 7 transmit power through a chain mechanism. The chain mechanism includes a drive sprocket 8 fixedly connected to the output shaft of the drive motor 4, a driven sprocket 9 fixedly connected to the rotating shaft 7, and a chain that is fitted around both the drive sprocket 8 and the driven sprocket 9. The outer diameter of the drive sprocket 8 is smaller than the outer diameter of the driven sprocket 9 (approximately 3-5 times). The top plate 1b is provided with a relief groove 1b1, through which part of the cage-like body 3 passes. The support 1 is equipped with a strip-shaped chute 11. Specifically, a base 12 is integrally fixed to the bottom of the chute 11, and the base 12 is fixedly connected to the top plate 1b. The chute 11 has a first section 11a that is vertically inclined and a second section 11b that is connected to the lower end of the first section 11a and is horizontally arranged. The second section 11b passes through the opening of the cage-like body 3. The bottom surface of the second section 11b is inclined, and a notch 11b1 is provided on one side of the second section 11b at the lowest point of the bottom surface. The cage-like body 3 has several circumferentially distributed discharge ports 3a, and each discharge port 3a is arranged along the length direction of the cage-like body 3. A flexible receiving plate 13 is fixed to the side of one of the discharge ports 3a, and the lower end of the flexible receiving plate 13 extends to the bottom of the material frame 2. A protective cover 14 is also fixedly connected to the top plate 1b. The cage-like body 3 is located inside the protective cover 14, and the upper end of the first section 11a of the chute 11 extends out of the protective cover 14.

[0037] Furthermore, such as Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, the cage-like body 3 includes a circular plate 3b, an annular plate 3c opposite to the circular plate 3b, and several connecting rods 3d fixedly connected between the circular plate 3b and the annular plate 3c. A material discharge port 3a is formed between adjacent connecting rods 3d. The upper end of the flexible receiving plate 13 is fixedly connected to one of the connecting rods 3d, and the second segment 11b passes through the annular plate 3c. The connecting rod connected to the flexible receiving plate 13 is flat, and the flexible receiving plate 13 abuts against one side of the connecting rod 3d. The flexible receiving plate 13 and the connecting rod 3d are actually fixed together by fasteners. The remaining connecting rods 3d are round rods. Each connecting rod 3d, except the one connected to the flexible receiving plate 13, is fitted with a rubber sleeve 3f. Each connecting rod 3d is fixedly connected to the annular plate 3c by a screw 3e. The shank of the screw 3e passes through the annular plate 3c and is threaded into the connecting rod 3d. Each connecting rod 3d is welded to the circular plate 3b. The end of the connecting rod 3d connected to the flexible receiving plate 13 has an abutment step 3d1, and the inner edge of the annular plate 3c abuts against the abutment step 3d1. In this embodiment, the flexible receiving plate 13 is specifically a polyurethane plate.

[0038] In use, the material frame 2 is empty, and the lower end of the flexible receiving plate 13 is located inside the bottom of the material frame 2, at which time the flexible receiving plate 13 is in a fully released state. The robot arm picks up the processed workpiece and places it into the chute 11. The workpiece slides down the first section 11a of the chute 11 into the second section 11b of the chute 11. Since the second section 11b of the chute 11 is set in the horizontal direction, the bottom surface of the second section 11b is set at an inclination, and a notch 11b1 is provided on one side of the second section 11b at its lowest point. In this way, the workpiece that slides into the second section 11b of the chute 11 will slide out of the notch 11b1 by the bottom surface of the second section 11b. The cage-like body 3 has several circumferentially distributed drop ports 3a. A flexible receiving plate 13 is fixed to the side of one of the drop ports 3a. The lower end of the flexible receiving plate 13 extends to the bottom of the material frame 2. In this way, the workpiece that slides out of the notch 11b1 will fall down onto the flexible receiving plate 13 through the drop port 3a below it under its own weight, and finally fall into the material frame 2 along the flexible receiving plate 13.

[0039] As workpieces fall into the material frame 2, they accumulate. Once the workpieces reach a certain height, the drive motor 4 can be rotated at an angle to roll the flexible receiving plate 13 upwards to a certain height. This ensures that the flexible receiving plate 13 is not pressed down by the accumulated workpieces. The frequency of winding the flexible receiving plate 13 can be determined according to the number of workpieces placed in the material frame 2. For example, after placing 10 large workpieces in sequence, the flexible receiving plate 13 can be rolled upwards once, or after placing 20 small workpieces in sequence, the flexible receiving plate 13 can be rolled upwards once. The number of workpieces placed can be counted by setting a sensor on the robot arm. The robot arm counts once every time it picks up a workpiece.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
