Description

Technical Field

[0001] The present application relates to the field of plate conveying equipment, and in particular to a clamping feeder. Background Art

[0002] As social demands continue to increase, the way of industrial production is gradually changing towards high efficiency and high quality. Assembly line operation plays an important role in industrial production. Optimizing the assembly line is directly related to product quality and production efficiency. Among them, conveying equipment is one of the important equipment for the smooth operation of assembly line operation.

[0003] In the related art, a plate conveying roller is disclosed, which includes a conveying frame composed of two parallel straight beams, and conveying rollers with rubber roller sleeves are arranged at intervals along the length direction of the conveying frame. The rubber roller sleeve includes a first through hole sleeved with the conveying roller, and the two ends of the first through hole are expanded along its radial direction to form a second through hole. When the rubber roller sleeve is sleeved on the conveying roller, a blocking mechanism for blocking the door plate from sliding off the conveying roller is engaged in the gap between the second through hole and the conveying roller, and a limiting mechanism for limiting the falling off of the blocking mechanism is also provided on the conveying roller. The plate is placed above the conveying roller and moves with the rotation of the conveying roller, so that the plate is conveyed to each process step.

[0004] Regarding the above-mentioned related technologies, the inventor believes that the movement method of the plate needs to meet the process requirements of the subsequent process. Therefore, when the subsequent process needs to process the stationary plate, the conveyor roller needs to turn, stop or retreat quickly. Under the action of inertia, the plate may move relative to the conveyor roller, resulting in insufficient feeding accuracy. Summary of the invention

[0005] In order to improve the feeding method and enhance the feeding accuracy, the present application provides a clamping feeder.

[0006] The present application provides a clamping feeder adopting the following technical solution:

[0007] A clamping feeder comprises a support seat for supporting a sheet material, a moving block is slidably connected to the support seat, a driving assembly for driving the moving block to slide is provided on one side of the moving block, a feeding assembly is provided on the moving block, the feeding assembly comprises a feeding roller rotatably connected to the moving block, the sheet material is located between the feeding roller and the support seat, and a push plate is provided on the downstream side of the feeding roller along the moving direction of the sheet material, one side of the push plate is fixedly connected to the feeding roller, and the other side is away from the feeding roller and abuts against the sheet material.

[0008] By adopting the above technical solution, the driving component drives the moving block to move forward, that is, the moving direction of the moving block is the same as the moving direction of the plate, the feeding roller moves with the moving block, and the moving direction of the feeding roller is toward the side where the push plate is located. At the same time, because the side of the push plate away from the feeding roller abuts against the plate, when the feeding roller moves, the feeding roller tends to rotate relative to the feeding roller under the obstruction of the push plate, and the pressure of the push plate on the plate gradually increases, thereby enhancing the friction between the push plate and the plate. The push plate drives the plate to move synchronously through the friction force. When the movable block moves backward, the moving direction of the feed roller is away from the side where the push plate is located. Therefore, the push plate is subjected to the resistance exerted by the sheet material on it, that is, the force opposite to the moving direction of the feed roller. Therefore, the push plate and the feed roller tend to rotate toward the side away from the sheet material. Therefore, the friction between the push plate and the sheet material is not enough to drive the sheet material to retreat synchronously with the movable block, and so on. The sheet material is intermittently conveyed and moved. At the same time, the friction between the push plate and the sheet material hinders the inertial movement of the sheet material, thereby improving the accuracy of the sheet material movement, meeting the processing requirements of different processes, and improving the production efficiency and quality of the product.

[0009] Optionally, the driving assembly includes a fixed block arranged on the moving block, one end of the fixed block is rotatably connected to a driving rod, an end of the driving rod away from the fixed block is rotatably connected to the driving block, a driving disk is provided on one side of the driving block, the driving block is located at an eccentric position of the driving disk, and a driving motor is provided at the center of the driving disk.

[0010] By adopting the above technical solution, the driving motor drives the driving disk to rotate, and the driving block makes a circular motion around the rotation center of the driving disk. During the rotation of the driving block, the driving block drives the fixed block to move through the driving rod, and the fixed block drives the moving block to translate on the support seat, thereby the driving assembly drives the moving block to translate back and forth.

[0011] Optionally, the driving block is slidably connected to the driving disk, and a fixing member for locking the driving disk and the driving block is provided between the driving disk and the driving block.

[0012] By adopting the above technical solution, the position of the driving block on the driving disk is adjusted, and then the driving block is connected and fixed to the driving disk through a fixing part, thereby adjusting the moving range of the driving block on the horizontal plane, thereby changing the moving distance of the moving block, thereby controlling the length of the sheet material fed each time, thereby meeting different processing requirements and production specifications.

[0013] Optionally, a fixing plate is provided on the feeding roller, a first spring connecting the fixing plate and the fixing block is provided between the fixing plate and the fixing block, and the push plate is pressed against the sheet material through the first spring.

[0014] By adopting the above technical scheme, under the support of the fixed block, the first spring applies a thrust to the fixed plate, so that the feed roller tends to rotate, so that the push plate is always pressed against the sheet material. Therefore, when the movable block completes the backward movement, the push plate and the sheet material abut against each other, and the movable block moves forward again. At this time, the push plate can directly push the sheet material to move, thereby preventing the feed roller from rotating, causing the push plate and the sheet material to abut against each other, causing the moving length of the sheet material to not meet the specified size, thereby improving the feeding accuracy.

[0015] Optionally, an adjusting screw is threadedly connected to the fixing block, one end of the first spring is fixedly connected to the adjusting screw, and the other end of the first spring is fixedly connected to the fixing plate.

[0016] By adopting the above technical solution, the adjusting screw is rotated, and the distance between the adjusting screw and the fixed plate is changed, thereby controlling the deformation of the first spring, and then controlling the pressure of the push plate on the sheet material. By controlling the adjusting bolt, the push plate pushes the sheet material forward when the moving block moves forward, and the push plate will not drive the sheet material to move backward when the moving block moves backward, thereby reducing the possibility of the sheet material size not meeting the requirements.

[0017] Optionally, a check assembly is provided on the support seat, and the check assembly includes a check roller rotatably connected to the support seat and parallel to the feed roller, and a check plate is provided on the side of the check roller located downstream in the moving direction of the sheet material, and the connection structure between the check plate and the check roller is the same as the connection structure between the push plate and the feed roller.

[0018] By adopting the above technical solution, when the moving block moves backward, the sheet material may tend to move backward due to the friction force applied by the push plate. At this time, the check plate is pressed against the sheet material, and as the tendency of the sheet material to move backward increases, the pressure applied by the check plate on the sheet material increases, thereby preventing the sheet material from moving backward and reducing errors.

[0019] Optionally, a support plate is provided on the non-return roller, and a second spring for connecting to the support seat is provided on the support plate, and the non-return plate is pressed against the sheet material through the second spring.

[0020] By adopting the above technical solution, the second spring makes the non-return plate always abut against the sheet material, so that the non-return plate always plays a non-return role.

[0021] Optionally, a guide assembly is provided on the support seat at one end upstream of the sheet material moving direction, and the guide assembly includes guide columns arranged on both sides of the support seat, the guide columns are slidably connected to the support seat in a direction parallel to the axis of the feed roller, and a locking piece is provided between the guide columns and the support seat.

[0022] By adopting the above technical solution, the position and relative distance of the guide column are adjusted, and the sheet is locked and fixed with the support seat through a locking piece. Before reaching the feed roller, the sheet first moves between the guide columns located on both sides of the support seat. The guide columns limit the movement direction of the sheet on both sides of the sheet, thereby moving the sheet to directly below the feed roller.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The feeding assembly enables the sheet to move intermittently, and the friction between the push plate and the sheet hinders the inertial movement of the sheet, thereby improving the accuracy of sheet movement, meeting the processing requirements of different processes, and improving the production efficiency and quality of the product;

[0025] 2. The non-return component prevents the sheet from moving backward, reduces errors and improves feeding accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The present application embodiment discloses a clamp-type feeder. Figure 1 and Figure 2The clamp feeder includes a support seat 1, and two mutually parallel guide rods 11 are fixed inside the upper end of the support seat 1. The two guide rods 11 are slidably connected with moving blocks 2, and the moving blocks 2 are slidably connected with the bottom surface of the support seat 1. A feed port 12 is provided on one side of the upper end of the support seat 1, and a discharge port 13 is provided on the other side. The sheet material 7 enters from the feed port 12 and passes through the discharge port 13. The sheet material 7 is located between the two moving blocks 2 and abuts on the bottom surface of the support seat 1. The moving direction of the sheet material 7 is parallel to the direction of the guide rods 11. A support pad 15 perpendicular to the guide rods 11 is fixed on the bottom surface of the support seat 1. The support pad 15 is located between the two moving blocks 2, and the sheet material 7 abuts on the support pad 15. The support pad 15 is used to reduce the shaking of the sheet material 7 and improve the stability of the movement of the sheet material 7.

[0033] Reference Figure 2 and Figure 3 A feeding assembly 3 for conveying the sheet material 7 is provided between the two moving blocks 2, a driving assembly 4 for driving the feeding assembly 3 is provided on the outer side of the support seat 1, and a guide assembly 5 for guiding the sheet material 7 is provided at one end of the support seat 1 close to the feed port 12. The sheet material 7 passes through the feed port 12 through the guide assembly 5, and at the same time, the driving assembly 4 drives the feeding assembly 3 to continuously move the sheet material 7, and the sheet material 7 passes through the discharge port 13 under the drive of the feeding assembly 3.

[0034] Two waist-shaped holes 14 are provided on one side of the support seat 1 outside the feed port 12, and the two waist-shaped holes 14 are opposite and parallel. The guide assembly 5 includes guide columns 51 corresponding to the waist-shaped holes 14 one by one, and the two guide columns 51 can approach or move away from each other along the direction of the waist-shaped holes 14. A positioning hole 511 is provided on the guide column 51, and the positioning hole 511 is directly opposite to the waist-shaped hole 14, and a locking member for locking the guide column 51 and the support frame is provided between the guide column 51 and the support frame. The locking member is configured as a locking bolt and a locking nut, and the locking bolt and the locking nut are not shown in the figure. One end of the locking bolt passes through the positioning hole 511 and the waist-shaped hole 14 and is threadedly connected to the locking nut, the nut of the locking bolt abuts against the side of the guide column 51, and the locking nut abuts against the side of the support seat 1, thereby fixing the guide column 51 and the support seat 1.

[0035] The sheet 7 moves under the restriction of the two guide pillars 51, aligns and passes into the feed port 12. When the specifications of the sheet 7 are changed, the locking nut is screwed to adjust the position and relative distance of the two guide pillars 51, so as to adapt to the width of the sheet 7 and the corresponding direction of entering the feed port 12, thereby improving the applicability of the guide assembly 5 to sheets 7 of different specifications.

[0036] The feeding assembly 3 includes a feeding roller 31 arranged between two moving blocks 2. The feeding roller 31 is located above the sheet 7. The axis of the feeding roller 31 is parallel to the plane where the sheet 7 is located, and the axis of the feeding roller 31 is perpendicular to the moving direction of the sheet 7. An eccentric sleeve is installed on the side of the moving block 2 close to the feeding roller 31, and a bearing is installed in the eccentric sleeve. The moving block 2 is rotatably connected to the end of the feeding roller 31 through the bearing. By adjusting the angle of the eccentric sleeve, the distance between the lower side of the feeding roller 31 and the bottom surface of the support seat 1 can be quickly adjusted to adapt to sheets 7 of different thicknesses. The feeding assembly 3 also includes a push plate 32 arranged on the side of the feeding roller 31 close to the discharge port 13. One side of the push plate 32 is fixedly connected to the feeding roller 31, and the other side gradually deviates from the feeding roller 31 and abuts against the sheet 7. At this time, the end of the push plate 32 abutting against the sheet 7 has a certain inclination relative to the feeding roller 31, and the included angle with the sheet 7 is an acute angle.

[0037] When the two moving blocks 2 move forward synchronously along the moving direction of the sheet material 7, the moving block 2 drives the feed roller 31 to move, and the sheet material 7 applies a resistance to the push plate 32 in the opposite direction of the moving direction of the moving block 2, so that the feed roller 31 rotates and presses the push plate 32 against the sheet material 7, thereby increasing the pressure and static friction of the push plate 32 on the sheet material 7, thereby pushing the sheet material 7 and the moving block 2 to move synchronously; when the moving block 2 moves backward, the resistance of the sheet material 7 to the push plate 32 is also opposite to the moving direction of the moving block 2 at this time, so that the feed roller 31 rotates and reduces the pressure of the push plate 32 on the sheet material 7, thereby not driving the sheet material 7 to move backward.

[0038] Reference Figure 1 and Figure 4 , the driving assembly 4 drives the two moving blocks 2 to move synchronously, so that the feeding assembly 3 works. The driving assembly 4 includes a fixed block 41, and the ends of the two moving blocks 2 close to the feed port 12 are fixedly connected to the fixed block 41. One end of the fixed block 41 is located outside the support seat 1, and is rotatably connected to a driving rod 42, and the end of the driving rod 42 away from the fixed block 41 is rotatably connected to a driving block 43, and the side of the driving block 43 away from the driving rod 42 is slidably connected to a driving disk 44, and a fixing member for locking the two is provided between the driving block 43 and the driving disk 44. A driving motor for driving the driving disk 44 to rotate is provided on the side of the driving disk 44 away from the driving block 43, and the driving motor is not shown in the figure.

[0039] The driving disk 44 is provided with a pitch-adjusting groove 441 distributed along the diameter of the driving disk 44. The pitch-adjusting groove 441 has a narrow notch and a wide bottom, and is T-shaped. The driving block 43 is inserted into the pitch-adjusting groove 441 and is slidably connected to the driving disk 44 through the pitch-adjusting groove 441. The fixing member is a pitch-adjusting screw 45. One end of the pitch-adjusting screw 45 is located in the pitch-adjusting groove 441 and is rotatably connected to the pitch-adjusting block. The other end passes through the pitch-adjusting groove 441 along the direction of the pitch-adjusting groove 441 and is threadedly connected to a limit block 46. The limit block 46 is fixedly connected to the driving disk 44. By rotating the pitch-adjusting screw 45, the eccentric distance of the driving block 43 on the driving disk 44 is adjusted, thereby changing the translation distance of the fixed block 41 and the moving block 2, thereby corresponding to the moving length of the sheet material 7 each time it moves.

[0040] When the motor is driven, the driving disk 44 rotates, and the driving block 43 makes a circular motion around the center of the driving disk 44, and drives the fixed block 41 to move through the driving rod 42, and the fixed block 41 drives the moving block 2 to translate synchronously.

[0041] In order to facilitate the adjustment of the relative position of the driving block 43 and the driving disk 44, the driving rod 42 includes a first connecting rod 421, a second connecting rod 422 and a connecting cylinder 423. One end of the first connecting rod 421 is inserted into the connecting cylinder 423 and is threadedly connected to the connecting cylinder 423. One end of the second connecting rod 422 is also inserted into the connecting cylinder 423 and is threadedly connected to the connecting cylinder 423. The thread directions of the first connecting rod 421 and the connecting cylinder 423 are opposite to those of the second connecting rod 422 and the connecting cylinder 423. The other end of the first connecting rod 421 is rotatably connected to the fixing block 41, and the other end of the second connecting rod 422 is rotatably connected to the driving block 43.

[0042] By rotating the connecting cylinder 423 , the first connecting rod 421 and the second connecting rod 422 are relatively moved closer or farther away, thereby adjusting the distance between the driving block 43 and the fixing block 41 , thereby quickly adjusting the moving distance of the sheet material 7 each time.

[0043] Each time the moving block 2 moves backward, the feed roller 31 and the push plate 32 rotate toward the side away from the sheet material 7 under the action of resistance, so that the push plate 32 reduces the degree of contact with the sheet material 7; when the moving block 2 is driven forward again, the feed roller 31 and the push plate 32 may rotate toward the side of the sheet material 7 again and contact the sheet material 7 again, but before the push plate 32 contacts and pushes the sheet material 7 to move, the moving block 2 will move a certain distance in advance, thereby reducing the feeding accuracy.

[0044] Therefore, refer to Figure 1 and Figure 2A fixing plate 33 is fixedly connected to the upper end of the feed roller 31 near the fixing block 41, and a first spring 34 in a compressed state is arranged between the fixing plate 33 and the fixing block 41. One end of the first spring 34 is fixedly connected to the fixed bottom plate, and the other end is fixedly connected to an adjusting screw 35, and the end of the adjusting screw 35 away from the first spring 34 passes through the fixing block 41 and is threadedly connected to the fixing block 41.

[0045] Since the first spring 34 is in a compressed state, the first spring 34 pushes the fixed plate 33 away from the fixed plate 33, drives the feeding roller 31 to rotate, and makes the push plate 32 press against the sheet 7, thereby reducing the possibility of reduced feeding accuracy caused by the push plate 32 being separated from the sheet 7. In addition, the adjustment screw 35 is rotated to change the distance between the adjustment screw 35 and the fixed plate 33, thereby controlling the compression amount of the first spring 34, and then adjusting the pressure of the push plate 32 on the sheet 7. Selecting a suitable pressure allows the push plate 32 to push the sheet 7 forward and cannot drive the sheet 7 to move backward.

[0046] In order to further improve the feeding accuracy of the sheet material 7 and reduce the possibility of the sheet material 7 moving backward, a non-return assembly 6 is provided at one end of the support seat 1 located at the discharge port 13. The non-return assembly 6 includes a non-return roller 61 rotatably connected to the support seat 1, the non-return roller 61 is located above the discharge port 13 and is arranged parallel to the feeding roller 31. A non-return plate 62 is fixed to the side of the non-return roller 61 away from the feeding roller 31, and the side of the non-return plate 62 away from the non-return roller 61 abuts against the sheet material 7, and the connection structure between the non-return plate 62 and the non-return roller 61 is the same as the connection structure between the push plate 32 and the feeding roller 31.

[0047] When the feed roller 31 and the push plate 32 drive the sheet material 7 to move forward, the sheet material 7 applies a friction force to the check plate 62, causing the check roller 61 to rotate in the direction away from the sheet material 7. At this time, the check plate 62 cannot prevent the sheet material 7 from moving forward; when the feed roller 31 and the push plate 32 move backward, the push plate 32 applies a backward force to the sheet material 7. At this time, the sheet material 7 has a tendency to move backward. At this time, the friction force applied by the sheet material 7 to the check plate 62 causes the check roller 61 to rotate toward the sheet material 7, thereby causing the check plate 62 to press against the sheet material 7 to prevent the sheet material 7 from moving backward.

[0048] The upper end of the non-return roller 61 is fixedly connected to a support plate 63, and a second spring 64 is provided between the support plate 63 and the support frame to fix the two. The second spring 64 is in a compressed state and pushes the non-return roller 61 to rotate toward the sheet material 7, so that the non-return plate 62 always abuts against the sheet material 7, thereby preventing the sheet material 7 from moving backward.

[0049] The implementation principle of a clamp-type feeder in an embodiment of the present application is as follows: the sheet material 7 passes through the feed port 12, the feed assembly 3, the discharge port 13 and the non-return assembly 6 in sequence under the restriction of the guide column 51, the driving motor drives the driving disk 44 to rotate, and the driving rod 42 drives the moving block 2 to translate as the driving disk 44 rotates. When the moving block 2 moves forward, the push plate 32 pushes the sheet material 7 forward. When the moving block 2 moves backward, the non-return plate 62 prevents the sheet material 7 from moving backward, and so on and so forth, and the sheet material 7 moves forward intermittently.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
