Description

Technical Field

[0001] This invention relates to the field of machining equipment technology, and in particular to a feeding device. Background Technology

[0002] In the stamping process, the stamping press presses the sheet metal in the mold into the corresponding shape, and then unloads the finished stamped part to the designated position. In existing technologies, there are two methods for unloading stamped parts: First, the stamped parts are manually removed and randomly placed in the hopper. Subsequent manual sorting and counting of the processed parts is required, which not only easily leads to errors in quantity counting but also increases labor intensity. Second, a sliding plate is inclined at the stamping press's outlet, and the stamped parts slide down the sliding plate into the hopper under their own weight. During unloading, stamped parts are prone to jamming, causing the press to stop. Furthermore, the random placement of stamped parts in the hopper, requiring subsequent manual sorting and counting, easily leads to errors in quantity counting and increases labor intensity.

[0003] Therefore, there is an urgent need to provide a feeding device to solve the above-mentioned technical problems. Summary of the Invention

[0042] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0045] like Figure 1 and Figure 2 As shown, this embodiment provides a feeding device that is used in conjunction with a machine tool and can be applied to an industrial internet-connected intelligent production line to transport the processed workpiece 100. Specifically, the feeding device includes a workpiece sliding mechanism 1, a workpiece bearing mechanism 2, a workpiece flipping mechanism 3, and a workpiece pushing mechanism 4.

[0046] The workpiece sliding mechanism 1 is inclined, with its higher end connected to the discharge port of the machine tool. The workpiece carrying mechanism 2 is connected to the lower end of the workpiece sliding mechanism 1. The workpiece flipping mechanism 3 is mounted on the workpiece sliding mechanism 1, and is used to allow the workpiece 100 on the workpiece sliding mechanism 1 to fall to the first station 21 of the workpiece carrying mechanism 2 in a preset posture. The workpiece pushing mechanism 4 is located on one side of the workpiece carrying mechanism 2, and is used to push the workpiece 100 at the first station 21 to the second station 22.

[0047] The unloading device provided in this embodiment allows the workpiece 100 discharged from the discharge port of the processing machine tool to slide down from the workpiece sliding mechanism 1 by its own gravity. After being flipped to a preset posture by the workpiece flipping mechanism 3, the workpiece falls to the first station 21 of the workpiece bearing mechanism 2. The workpiece pushing mechanism 4 pushes the workpiece 100 at the first station 21 to the second station 22. Each processed workpiece 100 is completed according to the above-mentioned process. The workpiece 100 is placed at the first station 21 in a preset posture. The workpiece pushing mechanism 4 pushes the workpiece 100 to the second station 22 respectively, so that the workpiece 100 is arranged in an orderly manner at the second station 22, realizing the orderly placement of the workpiece 100 and reducing the intensity of manual labor.

[0048] The workpiece sliding mechanism 1 includes two parallel and spaced-apart slide plates 11. The two slide plates 11 support both ends of the workpiece 100. The slide plates 11 are inclined so that the workpiece 100 slides down by its own weight. The slide plates 11 also reduce the contact area between the workpiece 100 and the workpiece sliding mechanism 1, thereby reducing the friction between the workpiece 100 and the workpiece sliding mechanism 1 and ensuring that the workpiece 100 can slide down smoothly. Each slide plate 11 has a side baffle 12 on its outer side. The distance between the side baffle 12 and the slide plate 11 is sufficient to accommodate the workpiece 100 without affecting the sliding of the workpiece. The side baffle 12 can prevent the workpiece 100 from detaching from the slide plate 11 and falling down, thus playing a stopping role.

[0049] Each side baffle 12 is also provided with a top baffle 13 at its upper end. The two top baffles 13 extend towards each other and are spaced apart. The top baffles 13 can also play a certain role in limiting the workpiece 100 and prevent the workpiece 100 from leaving the slide plate 11.

[0050] In this embodiment, the workpiece 100 is a stamped sheet metal part, the processing machine tool is a stamping machine, the two ends of the workpiece 100 are bent, and the angle of bending at both ends is obtuse with the middle part. The middle part of the workpiece 100 overlaps on the slide plate 11, and the two ends of the workpiece 100 are placed on the outside of the slide plate 11. The workpiece 100 can stably slide down along the slide plate 11.

[0051] In some other embodiments, the workpiece 100 can be of other shapes, and the workpiece sliding mechanism 1 can be adapted to the shape of the workpiece, without being specifically limited here.

[0052] like Figure 2 , Figure 3 and Figure 4 As shown, the workpiece flipping mechanism 3 is used to allow the workpiece 100 on the workpiece sliding mechanism 1 to fall to the first station 21 of the workpiece carrying mechanism 2 in a preset posture. In some embodiments, the workpiece flipping mechanism 3 includes a stop unit 31 and a flipping unit 32. The stop unit 31 is disposed on the workpiece sliding mechanism 1, and the flipping unit 32 is disposed on the workpiece sliding mechanism 1 and located downstream of the stop unit 31. The stop unit 31 is used to allow the workpiece 100 on the workpiece sliding mechanism 1 to fall orderly onto the flipping unit 32, and the flipping unit 32 is used to allow the workpiece 100 placed on the flipping unit 32 to fall to the first station 21 of the workpiece carrying mechanism 2 in a preset posture. The stop unit 31 allows the workpiece 100 to fall orderly onto the flipping unit 32 to ensure that the flipping unit 32 can allow the workpiece 100 to fall to the first station 21 in a preset posture, so that the flipping unit 32 can work normally.

[0053] The flipping unit 32 is located at the lower end of the workpiece sliding mechanism 1 to facilitate connection with the workpiece carrying mechanism 2, allowing the workpiece 100 to stably fall to the first station 21 of the workpiece carrying mechanism 2. The stop unit 31 is located upstream of the flipping unit 32, with the two spaced apart.

[0054] Optionally, the stop unit 31 includes a first stop 311 and a second stop 312 spaced apart along the length of the workpiece sliding mechanism 1. A workpiece can be accommodated at the workpiece sliding mechanism 1 position between the first stop 311 and the second stop 312. The first stop 311 and the second stop 312 can extend to stop the workpiece 100 or retract to release the workpiece 100, respectively. The cooperation of the first stop 311 and the second stop 312 allows the workpiece 100 to fall orderly onto the flipping unit 32. The first stop 311 is located upstream of the second stop 312. The workpiece sliding mechanism 1 position between the first stop 311 and the second stop 312 is designated as a storage position. Specifically, in actual operation, the first stop 311 extends to isolate the workpiece 100 upstream of the first stop 311 from the workpiece 100 at the storage position, and the second stop 312 extends to isolate the workpiece 100 at the storage position. The second stop 312 retracts, and the workpiece 100 at the storage position falls onto the flipping unit 32. The first stop 311 retracts, and the workpiece 100 upstream of the first stop 311 falls to the storage position. The first stop 311 and the second stop 312 cooperate to store the workpiece 100 at the storage position and to ensure that the workpiece 100 falls onto the flipping unit 32 in an orderly manner.

[0055] The first stop 311 and the second stop 312 are respectively disposed above the workpiece sliding mechanism 1. The first stop 311 and the second stop 312 respectively include a stop cylinder 3111 and a stop plate 3112. The output end of the stop cylinder 3111 is connected to the stop plate 3112. The stop cylinder 3111 drives the stop plate 3112 to extend so that the stop plate 3112 can be inserted between two adjacent workpieces 100 to separate the two adjacent workpieces 100. The structure is simple and the control method is simple.

[0056] In some other embodiments, the first stop 311 and the second stop 312 are disposed on the side of the workpiece sliding mechanism 1. The first stop 311 and the second stop 312 include a stop cylinder 3111 and a stop plate 3112. The stop cylinder 3111 drives the stop plate 3112 to extend so that the stop plate 3112 is inserted between two adjacent workpieces 100 to separate the two adjacent workpieces 100.

[0057] In order to allow the stop plate 3112 to be smoothly inserted between the two workpieces 100 to separate the two workpieces 100, the end of the stop plate 3112 is set in the shape of a wedge.

[0058] The flipping unit 32 is used to cause the workpiece 100 placed on the flipping unit 32 to fall to the first station 21 of the workpiece carrying mechanism 2 in a preset posture. In some embodiments, the flipping unit 32 includes a flipping disk 321 and a driving assembly 323. The flipping disk 321 is circumferentially provided with at least one workpiece contouring groove 322 for carrying the workpiece 100. The driving assembly 323 is drivenly connected to the flipping disk 321 and is used to drive the flipping disk 321 to rotate. After the flipping disk 321 rotates and the workpiece contouring groove 322 receives the workpiece 100 on the workpiece sliding mechanism 1, the workpiece 100 falls to the first station 21 as the flipping disk 321 continues to rotate.

[0059] Multiple workpiece contouring grooves 322 can be provided around the circumference of the flip disk 321. The number of workpiece contouring grooves 322 can be determined according to the size of the flip disk 321 and the size of the workpiece 100. In this embodiment, the flip disk 321 is provided with three workpiece contouring grooves 322. According to the shape of the workpiece 100, an L-shaped groove is cut on the circumferential edge of the flip disk 321 to form the workpiece contouring groove 322. The middle part of the workpiece 100 overlaps the bottom of the workpiece contouring groove 322, and one side of the workpiece 100 abuts against the side wall of the workpiece contouring groove 322. The bottom of the workpiece contouring groove 322 is connected to the workpiece sliding mechanism 1. The opening of the workpiece contouring groove 322 allows the workpiece 100 to slide into the workpiece contouring groove 322. The flip plate 321 rotates counterclockwise. When the workpiece 100 is in a vertical position, the workpiece 100 will not detach from the workpiece contouring groove 322 due to the limitation of the side wall of the workpiece contouring groove 322. As the flip plate 321 continues to rotate, the workpiece 100 is released from the opening of the workpiece contouring groove 322 and falls to the first station 21. The workpiece 100 is flipped 90°, that is, one side of the workpiece 100 is placed on the workpiece carrying mechanism 2, so that the workpiece pushing mechanism 4 can push the workpiece 100 to stack the workpieces together, making it easier for the worker to take away the workpiece 100 and saving the space used to place the workpiece 100.

[0060] Optionally, to reduce the driving force of the drive assembly 323, the rotating disk 321 includes two circular rotating plates with identical structures. The two rotating plates are spaced apart on a rotating shaft 327, which is connected to the drive end of the drive assembly 323. The distance between the two rotating plates is no greater than the length of the workpiece 100, so that the workpiece 100 can overlap the two rotating plates. Based on the structure of the workpiece 100 described above, the distance between the two rotating plates is no greater than the length of the middle portion of the workpiece 100.

[0061] The drive assembly 323 includes a drive motor and a reducer, with the reducer being configured to increase the torque of the drive motor.

[0062] The flipping unit 32 also includes a detection component, which includes a first detection element 324, a second detection element 325 and a third detection element 326.

[0063] The first detection element 324 is disposed on one side of the flip plate 321. The first detection element 324 is configured to detect whether the workpiece contouring groove 322 is positioned at a workpiece receiving station capable of receiving the workpiece 100 in the initial state. After confirming that the workpiece contouring groove 322 is positioned at the workpiece receiving station, the stop unit 31 actuates to cause the workpiece 100 to slide into the workpiece contouring groove 322. Specifically, the second stop 312 retracts to release the workpiece 100 from the storage position into the workpiece contouring groove 322, the second stop 312 extends, the first stop 311 retracts, the workpiece 100 slides to the storage position, and the first stop 311 extends to isolate the workpiece 100 at the storage position from the adjacent workpiece 100.

[0064] A round hole is provided on one side of the rotating disk 321. When the rotating disk 321 rotates, the first detection element 324 cannot detect the rotating disk 321, that is, when the round hole is directly opposite the first detection element 324, the workpiece contour groove 322 is placed at the workpiece receiving station.

[0065] After determining that the workpiece contouring groove 322 is located at the workpiece receiving station in the initial state, the rotation angle of the flipping disk 321 is controlled according to the number of workpiece contouring grooves 322, so that the next workpiece contouring groove 322 is placed at the workpiece receiving station. In this embodiment, three workpiece contouring grooves 322 are set on the flipping disk 321. One workpiece contouring groove 322 is placed at the workpiece receiving station, and the other workpiece contouring groove 322 is placed at the first station 21 and is in a state that allows the workpiece 100 to be flipped 90° and fall onto the workpiece bearing mechanism 2.

[0066] The second detection element 325 is disposed above the tilting disk 321. The second detection element 325 is configured to detect whether there is a workpiece 100 in the workpiece contouring groove 322 placed at the workpiece receiving station. After confirming that there is a workpiece 100 in the workpiece contouring groove 322, the drive assembly 323 drives the tilting disk 321 to rotate by a preset angle, so that the workpiece 100 in the workpiece contouring groove 322 falls onto the workpiece bearing mechanism 2.

[0067] The workpiece sliding mechanism 1 is provided with a first mounting bracket, and the second detection component 325 is mounted on the first mounting bracket.

[0068] The third detection element 326 is set at the first station 21. The third detection element 326 is used to detect whether there is a workpiece 100 at the first station 21. After the third detection element 326 detects that there is a workpiece 100 at the first station 21, the workpiece pushing mechanism 4 pushes the workpiece 100 at the first station 21 to the second station 22.

[0069] A second mounting bracket is provided on one side of the workpiece carrying mechanism 2, and the third detection component 326 is mounted on the second mounting bracket. Specifically, the second mounting bracket is placed between the two flip plates, without affecting the flip plates' flipping and the workpiece 100's slippage from the workpiece contour groove 322.

[0070] The first detection element 324, the second detection element 325, and the third detection element 326 can be photoelectric sensors, and no specific limitation is made here.

[0071] The workpiece pushing mechanism 4 is used to push the workpiece 100 at the first station 21 to the second station 22. In some embodiments, the workpiece pushing mechanism 4 includes a workpiece push plate 41 and a push driver 42. The drive end of the push driver 42 is connected to the workpiece push plate 41, and the push driver 42 is used to drive the workpiece push plate 41 to push the workpiece 100 from the first station 21 to the second station 22. The push driver 42 can be a cylinder or an electric push rod, which is not specifically limited here.

[0072] To avoid the aforementioned second mounting bracket, the workpiece pusher plate 41 is U-shaped. The middle part of the workpiece pusher plate 41 is connected to the output end of the push driver 42. The workpiece pusher plate 41 moves below the flip plate 321, and both ends of the workpiece pusher plate 41 are used to contact the two ends of the workpiece 100. The workpiece 100 is subjected to uniform force, and the workpiece 100 will not deflect during the pushing process, so as to stack the workpieces 100 together in an orderly manner. The workpiece 100 is pushed from the first station 21 to the second station 22. Along the pushing direction of the workpiece pushing mechanism 4, multiple workpieces 100 are stacked together, which serves to organize the workpieces 100, so that the unloaded workpieces 100 can be arranged in an orderly and neat manner. In addition, the number of times the workpiece pushing mechanism 4 pushes out the workpieces 100 is the number of stacked workpieces 100, so that the number of processed workpieces 100 can be automatically counted.

[0073] In some embodiments, the workpiece carrying mechanism 2 not only carries the workpiece 100 but also transports the stacked workpieces 100 to a designated position. The workpiece carrying mechanism 2 includes a belt conveyor, and a workpiece pushing mechanism 4 is disposed on one side of the belt conveyor. The conveying direction of the belt conveyor and the direction in which the workpiece pushing mechanism 4 pushes the workpiece 100 are perpendicular to each other in the same plane. The belt conveyor can transport the stacked workpieces 100 to the designated position. The structure of the belt conveyor is prior art and will not be described in detail here.

[0074] Optionally, a third station 23 is provided on the side of the belt conveyor opposite to the workpiece pushing mechanism 4. A fourth detection element 24 is provided at the third station 23. The fourth detection element 24 is configured to be triggered when the number of workpieces 100 accumulates to a preset number. The belt conveyor is then controlled to move in the conveying direction until the fourth detection element 24 is no longer triggered. As the workpieces 100 are continuously pushed to the second station 22, they are stacked sequentially, and the stacked workpieces 100 move in the direction pushed by the workpiece pushing mechanism 4. After the fourth detection element 24 detects a workpiece 100, it indicates that the stacking of that column of workpieces 100 is complete. The belt conveyor can then be controlled to move in the conveying direction, transporting the stacked column of workpieces 100 away from the second station 22, and creating a blank second station 22 on the belt conveyor for stacking a new column of workpieces 100. The number of workpieces 100 stacked in each column is fixed. Therefore, after the fourth detection element 24 detects the signal of workpiece 100, it proves that the number of workpieces 100 in this column has reached the preset value. It has a counting function with high counting accuracy, eliminating the need for manual counting of the number of workpieces 100. The fourth detection element 24 can be a photoelectric sensor.

[0075] In some embodiments, the fourth detection element 24 is a distance sensor. The distance between the fourth detection element 24 and the outermost workpiece 100 is obtained by the signal detected by the fourth detection element 24. When the value of the distance is less than or equal to a first preset value, the workpiece pushing mechanism 4 stops pushing the workpiece 100 and controls the belt conveyor to move in the conveying direction until the fourth detection element 24 is no longer triggered.

[0076] In other embodiments, the unloading device further includes a counter for measuring the number of times the workpiece pushing mechanism 4 pushes the workpiece 100, i.e., the number of stacked workpieces 100. After the number of times the workpiece pushing mechanism 4 pushes the workpiece 100 reaches a preset number, the workpiece pushing mechanism 4 stops pushing the workpiece 100 and returns to its initial position. The belt conveyor is then controlled to move to a preset distance in the conveying direction, conveying a stacked column of workpieces 100 away from the second station 22, and forming a blank second station 22 on the belt conveyor for stacking a new column of workpieces 100. Along the conveying direction of the belt conveyor, a fifth detection element 25 is provided downstream of the first station 21 on the belt conveyor. The fifth detection element 25 is configured to detect the workpiece 100 to remind the operator to remove the workpiece 100. After the fifth detection element 25 detects the signal of the workpiece 100, the belt conveyor is controlled to stop working, so that the second station 22 is formed at the position corresponding to the workpiece pushing mechanism 4. After receiving the detection signal from the fifth detection element 25, the controller can also notify the operator to remove the stacked workpieces 100.

[0077] Along the direction of the belt conveyor, a sixth detection element 26 is set at the other end of the belt conveyor. The sixth detection element 26 is located downstream of the fifth detection element 25. When the sixth detection element 26 detects workpiece 100, it means that the belt conveyor is full of workpiece 100. The belt conveyor can no longer rotate, and the unloading device will alarm to remind the operator to remove workpiece 100 in time. If workpiece 100 is not removed, the entire device will stop after the workpiece 100 at the second station 22 is piled up.

[0078] The fifth detection element 25 and the sixth detection element 26 can be photoelectric sensors or through-beam sensors, or other types of sensors, without specific limitations here.

[0079] When using the unloading device provided in this application, the workpiece 100 discharged from the discharge port of the processing machine tool slides down from the workpiece sliding mechanism 1 by its own gravity. The workpiece contouring groove 322 of the tilting disk 321 is connected to the end of the workpiece sliding mechanism 1 to support the workpiece 100. The first stop 311 and the second stop 312 are controlled to cooperate to make the workpiece 100 fall orderly onto the workpiece contouring groove 322 of the tilting disk 321. After detecting that there is a workpiece 100 in the workpiece contouring groove 322, the tilting disk 321 is tilted to flip the workpiece 100. Upon detection, workpiece 100 automatically falls to the first station 21 of the workpiece carrying mechanism 2 in a preset posture. After detecting the presence of workpiece 100 at the first station 21, the workpiece pushing mechanism 4 pushes the workpiece 100 at the first station 21 to the second station 22. Each processed workpiece 100 completes the above process, and each workpiece 100 is placed at the first station 21 in a preset posture. The workpiece pushing mechanism 4 then pushes each workpiece 100 to the second station 22, arranging the workpieces 100 in an orderly manner at the second station 22. After the fourth detection piece 24 at the third station 23 detects workpiece 100, it proves that the column of workpieces 100 is full. The belt conveyor is then controlled to transport the full workpieces 100 to a designated position, and the second station 22 of the belt conveyor is left empty to prepare for the subsequent arrangement of workpieces 100. The feeding device provided in this application realizes the orderly placement of workpieces 100, and the number of workpieces 100 can be counted by the number of times the workpiece pushing mechanism 4 pushes out workpieces 100. The accuracy of the count is high, which reduces the intensity of manual labor.
