Description

Technical Field

[0001] The utility model relates to the field of automobile stamping auxiliary equipment, in particular to a belt conveyor turning mechanism. Background Art

[0002] In the production of stamping automation production lines for automotive parts, such as Figure 1 As shown, the specific process of sheet material conveying is as follows: first, the robot grabs the sheet material from the destacking station and then places it on the destacking belt conveyor 70. The sheet material is conveyed forward on the destacking belt conveyor 70 and passes through the cleaning machine 80 and the oiling machine 90 in turn, and is finally transported to the centering belt conveyor 10. When the oiling machine 90 is not needed in the production process of some stamping products or the oiling machine 90 has an abnormality, the oiling machine 90 will be driven to a station outside the production line, resulting in a vacant space between the cleaning machine 80 and the centering belt conveyor 10. At this time, the sheet material cannot be normally conveyed from the cleaning machine to the centering belt conveyor 10, which will cause the production line to be abnormal or stop, affecting the continuous production of the product.

[0003] The technical solution disclosed in the title "Turning-type magnetic belt conveyor for stamping automated production line" (publication number CN209258955U, hereinafter referred to as document 1) includes a belt conveyor frame, a conveyor belt with a roller driven by a power source is arranged on the upper part of the belt conveyor frame; a working oil cylinder is arranged at the lower part of the belt conveyor frame; a supporting connecting rod is hinged at the end of the piston rod of the working oil cylinder, and the other end of the supporting connecting rod is hinged to the bottom of the workpiece receiving device; a connecting rod is arranged on one side of the workpiece receiving device, and the other end of the connecting rod is hinged to the belt conveyor frame above the working oil cylinder;

[0004] The flipping scheme provided in the above-mentioned document 1 mainly has the following defects: the oil cylinder drives the connecting rod to rotate by supporting the connecting rod. Since the speed of the oil cylinder is generally fast, the rotation speed of the connecting rod is fast. At the same time, no corresponding limiting structure is set on the belt conveyor frame. When the receiving device is flipped up, it is difficult to ensure that the conveying surface of the receiving device is horizontal and to make the receiving device and the conveyor belt connected smoothly, which affects the transportation of the sheet material; at the same time, when the rotation angle of the connecting rod is too large, it is easy for the connecting rod to hit the belt conveyor frame, causing the entire device to produce a large vibration and reducing the service life of the device. Utility Model Content

[0005] The utility model aims to provide a belt conveyor turning mechanism to ensure that the replacement belt conveyor is accurately turned up to a horizontal state as a whole and is in a forward connection state with the centering belt conveyor, so as to facilitate the smooth conveyance of the sheet material to the centering belt conveyor.

[0006] The utility model can be realized through the following technical solutions: A belt conveyor flipping mechanism, at one end of the centering belt conveyor, a supplementary belt conveyor is rotatably arranged. On the frame of the fixed centering belt conveyor, a support plate is arranged. The bracket of the supplementary belt conveyor is fixedly connected to the first end of the connecting arm plate. The connecting arm plate is hinged to the support plate by a pin shaft arranged horizontally. The pin shaft perpendicular to the conveying direction of the material is arranged near the second end of the connecting arm plate. A limiting block is arranged on the support plate. When the driving mechanism drives the connecting arm plate and the supplementary belt conveyor to swing around the pin shaft, the end of the supplementary belt conveyor far from the pin shaft swings from the low position to the high position where the supplementary belt conveyor is horizontal, and the limiting block is in contact and cooperation with the second end of the connecting arm plate.

[0007] Compared with the prior art, the utility model has the following beneficial effects:

[0008] When it is necessary to use the supplementary belt conveyor for compensation, under the action of the driving mechanism, the supplementary belt conveyor and the connecting wall plate swing upward with the pin shaft as the fulcrum. By using the contact and cooperation between the limiting block and the second end of the connecting arm plate, the further upward swing of the connecting wall plate is blocked. Coupled with the supporting effect of the driving mechanism on the supplementary belt conveyor, it ensures that the overall supplementary belt conveyor presents a horizontal state. The top of the overall horizontal supplementary belt conveyor is flush with the top of the centering belt conveyor, which is convenient for the sheet material to be conveyed onto the centering belt conveyor.

[0018] Please refer to Figures 1-9 As shown in the figure, for a belt conveyor turning mechanism, a supplementary belt conveyor 20 is rotatably arranged at one end of the centering belt conveyor 10. A support plate 40 is arranged on the frame 11 of the fixed centering belt conveyor 10. The bracket 21 of the supplementary belt conveyor 20 is fixedly connected to the first end 50A of the connecting arm plate 50. The connecting arm plate 50 is hinged to the support plate 40 by a pin shaft 60 arranged horizontally. The pin shaft 60 perpendicular to the conveying direction of the material is arranged close to the second end 50B of the connecting arm plate 50. A limiting block 41 is arranged on the support plate 40. When the driving mechanism drives the connecting arm plate 50 and the supplementary belt conveyor 20 to swing around the pin shaft 60, the end of the supplementary belt conveyor 20 far from the pin shaft 60 swings from a low position to a high position where the supplementary belt conveyor 20 is horizontal. The limiting block 41 is in contact and cooperation with the second end 50B of the connecting arm plate 50.

[0019] In the above solution, when it is necessary to use the supplementary belt conveyor 20 for supplementary positioning, the driving force of the driving mechanism directly acts on the bracket 21 of the supplementary belt conveyor 20, so that the supplementary belt conveyor 20 and the connecting arm plate 50 swing upward with the pin shaft 60 as the fulcrum. Finally, one end of the supplementary belt conveyor 20 swings from a low position to a high position where the whole is horizontal. At this time, the limiting block 41 is in contact and cooperation with the second end 50B of the connecting arm plate 50, preventing the connecting arm plate 50 from swinging further upward. Coupled with the supporting effect of the driving mechanism on the supplementary belt conveyor 20, it ensures that the supplementary belt conveyor 20 is in a horizontal state as a whole. The top of the supplementary belt conveyor 20 in a horizontal state as a whole is flush with the top of the centering belt conveyor 10, which is convenient for the sheet material to be conveyed onto the centering belt conveyor 10. Therefore, when there is a vacancy between the cleaning machine 80 and the centering belt conveyor 10, at this time, the sheet material can be conveyed to the centering belt conveyor 10 through the supplementary belt conveyor 20, ensuring the continuous processing of the sheet material.

[0020] The connecting arm plate 50 is formed by extending the first plate 501 and the second plate 502 in an angled profile, and the pin 60 is hinged to the plate end of the first plate 501 away from the second plate 502; the second plate 502 constituting the first end 50A of the connecting arm plate 50 is fixedly connected to the plate edge of the first plate 501 away from the second plate 502, and the third plate 503 used to connect the bracket 21 is arranged perpendicular to the plate surface of the connecting arm plate 50; the connecting arm plate 50 with an angled profile and the pin 60 are installed on the first plate 501. The function of the plate end of plate 501 away from plate No. 2 502 is: when the connecting arm plate 50 swings upward, one end of the supplementary belt conveyor 20 will not interfere with the end of the centering belt conveyor 10, while also ensuring that one end of the supplementary belt conveyor 20 can swing to a position close to the feeding end of the centering belt conveyor 10, so that the supplementary belt conveyor 20 and the centering belt conveyor 10 are in a state of extended connection; the plate No. 3 503 can be connected to the bracket 21 by bolt connection.

[0021] A support base 42 for connecting to the frame 11 is fixed to the bottom of the support plate 40; the support base 42 and the frame 11 can be connected by bolts.

[0022] The support seat 42 is provided with a shock-absorbing block 421. When the length direction of the No. 2 plate 502 swings from horizontal to plumb, the No. 3 plate 503 and the shock-absorbing block 421 form a resistance fit; when the replacement belt conveyor 20 is not needed, the driving mechanism drives the replacement belt conveyor 20 and the connecting arm plate 50 to swing downward. During the process of the length direction of the No. 2 plate 502 swinging from horizontal to plumb, one end of the No. 3 plate 503 will hit the shock-absorbing block 421 on the support seat 42. The shock-absorbing block 421 is used to cushion the connecting arm plate 50 when it swings downward, thereby reducing the vibration of the connecting arm plate 50 to the equipment when it swings downward.

[0023] Two travel detection switches 43 are installed on the support plate 40, which are used to detect the position of the bracket 21 when it swings upward and downward respectively; through the travel detection switch 43, it is detected whether the filling belt conveyor 20 is in a horizontal state after flipping, thereby reducing the occurrence of collisions of sheet materials during transportation.

[0024] The support plate 40 includes a groove-shaped cavity 44, the plate body of the connecting arm plate 50 is placed in the groove-shaped cavity 44, the two end sections of the pin shaft 60 are inserted into the connecting holes on the support plate 40, and the middle section is placed in the connecting hole on the connecting arm plate 50. The first plate 501 is rotatably arranged in the groove-shaped cavity 44; when the driving mechanism drives the connecting arm plate 50 to rotate, the first plate 501 rotates around the pin shaft 60 in the groove-shaped cavity 44, thereby realizing the swing of the replacement belt conveyor 20.

[0025] The driving mechanism includes a cylinder 31 installed on the frame 11. A slider 33 is fixed to the rod end of the piston rod 32 of the cylinder 31. The slider 33 is slidably engaged with a slide rail 34 on the frame 11, and the extending direction of the slide rail 34 is the same as the conveying direction of the material. One end of a connecting rod 35 is hinged to the slider 33, and the other end of the connecting rod 35 is hinged to the bracket 21. When it is necessary to use the supplementary belt conveyor 20 for supplementary positioning, the cylinder 31 is started. The piston rod 32 quickly extends out of the cylinder body of the cylinder 31. The piston rod 32 drives the slider 33 to slide on the slide rail 34. The slider 33 drives the lower end of the connecting rod 35 to move away from the cylinder 31, so that the upper end of the connecting rod 35 pushes the bracket 21 to swing upward, thereby realizing the upward flipping of the supplementary belt conveyor 20. When the supplementary belt conveyor 20 is not needed, the piston rod 32 quickly extends into the cylinder body of the cylinder 31, so that the slider 33 drives the lower end of the connecting rod 35 to move toward the cylinder 31, so that the upper end of the connecting rod 35 drives the bracket 21 to swing downward, thereby realizing the downward flipping of the supplementary belt conveyor 20.
