Description

Technical Field

[0001] This utility model relates to the field of material conveying, and in particular to a positioning device and a paper feeding line. Background Technology

[0002] In automated book production lines, the paper feeding line is the core component for achieving continuous production. Among these, the pusher flag, as a key technology for transferring and mounting pages, works in conjunction with a chain device to continuously push the paperboard. However, the pusher flag requires extremely high precision in its positioning when repeatedly performing step-by-step forward movements.

[0003] However, traditional flag-pushing positioning mainly relies on mechanical limiting structures. This method lacks the ability to adapt to dynamic changes in the production line. The detector position cannot flexibly change the detection benchmark according to the production line conditions, changes in material specifications, and other scenarios. When the flag-pushing angle changes, the production line speed fluctuates, or there are slight differences in material size, the accuracy of the positioning benchmark cannot be guaranteed, which ultimately leads to the accumulation of flag-pushing positioning deviations. Traditional positioning devices are difficult to meet the requirements of high-precision repeatable positioning, affecting the stability of page transmission and the quality of subsequent processing.

[0040] The following is combined Figures 1 to 2 The embodiments of this utility model are described below.

[0041] A positioning device according to a first aspect embodiment of the present invention includes:

[0042] The frame 101 is vertically provided with a vertical support;

[0043] A first adjustment frame is mounted on the vertical support and slides along the vertical direction of the vertical support.

[0044] The second adjustment frame is disposed on the first adjustment frame, and the second adjustment frame slides along the horizontal direction of the first adjustment frame;

[0045] A detection component is provided on the second adjustment frame, and the detection component is used to detect the position of the push flag 600.

[0046] The positioning device in this embodiment is used for positioning the pusher flag 600 in the paper feeding line. When the paper feeding line is running, the pusher flag 600 moves forward in a stepping motion under the drive of the chain device to push the cardboard. If it is necessary to adjust the stepping position of the pusher flag 600, for example, when the position of the pusher flag 600 changes in the vertical or horizontal direction, the operator can manually or with the help of a small drive device to make the first adjustment frame slide up and down along the vertical support, and make the second adjustment frame slide horizontally along the first adjustment frame, thereby adjusting the detection component to a suitable position. After the position of the detection component is adjusted, during the movement of the pusher flag 600, when the pusher flag 600 enters the detection range of the detection component, the detection component transmits the detected pusher flag 600 position signal to the control system in real time, realizing accurate detection and positioning of the pusher flag 600 position.

[0047] With a first adjustable frame that can slide up and down and a second adjustable frame that can slide horizontally, the position of the detection components can be flexibly adjusted according to changes in production line conditions, such as changes in the angle of the push flag 600 and differences in material specifications, thereby changing the detection benchmark. Compared with traditional mechanical limit structures, the adaptability to different working scenarios is greatly improved. Moreover, the position of the detection components can be flexibly adjusted, ensuring accurate positioning benchmark even under conditions such as changes in the angle of the push flag 600, fluctuations in production line speed, and slight differences in material size. This effectively avoids the accumulation of positioning deviations and meets the high-precision repeatability requirements of the push flag 600.

[0048] Specifically, the vertical support includes a first guide rod 201, a second guide rod 206, a first connecting seat 202, and a second connecting seat 207; the frame 101 has screw holes on its side, and both the first connecting seat 202 and the second connecting seat 207 have through fixing holes. Screws are provided at the fixing holes, and the screws pass through the fixing holes and are threaded into the screw holes to fix the first connecting seat 202 and the second connecting seat 207 onto the frame 101; the first connecting seat 202 has a first vertical hole 203, and the first guide rod 201 is vertically inserted into the first vertical hole 203; the second connecting seat 207 has a second vertical hole 208, and the second guide rod 206 is vertically inserted into the second vertical hole 208; both ends of the first adjusting frame are connected to the first guide rod 201 and the second guide rod 206 respectively, and the first adjusting frame slides along the vertical direction of the first guide rod 201 and the second guide rod 206.

[0049] Screws pass through the fixing holes of the first connecting seat 202 and the second connecting seat 207, and then are screwed into the screw holes on the side of the frame 101 to fix the first connecting seat 202 and the second connecting seat 207 to the frame 101. The first guide rod 201 is vertically inserted into the first vertical hole 203 of the first connecting seat 202, and the second guide rod 206 is vertically inserted into the second vertical hole 208 of the second connecting seat 207. The two parallel first guide rods 201 and the second guide rod 206, together with the first connecting seat 202 and the second connecting seat 207 connected to the frame 101, form a stable support structure that can withstand various forces generated during the up-and-down sliding of the first adjusting frame. The vertical support adopts a modular design and is assembled by screw connection. After long-term operation of the equipment, if a component such as the guide rod is worn or the connecting seat is damaged, the corresponding screw can be easily unscrewed and the component can be replaced individually without replacing the entire vertical support structure.

[0050] Specifically, the first connecting seat 202 has a first groove 204, which communicates with the first vertical hole 203; the first connecting seat 202 has a first locking hole that passes through the first groove 204, and a first locking bolt 205 passes through the first locking hole.

[0051] The second connecting seat 207 has a second groove 209, which communicates with the second vertical hole 208; the second connecting seat 207 has a second locking hole that passes through the second groove 209, and a second locking bolt 210 passes through the second locking hole.

[0052] When it is necessary to lock and fix the first guide rod 201 and the second guide rod 206, use a wrench to gradually tighten the first locking bolt 205 and the second locking bolt 210; as the bolts are tightened, the bolt nuts apply pressure to the connecting seat portions on both sides of the first groove 204 and the second groove 209, causing these two portions to gradually move closer together; since the first groove 204 and the second groove 209 are connected to the first vertical hole 203 and the second vertical hole 208, this tendency to move closer together will cause the first vertical hole 203 and the second vertical hole 208 to move closer together. The two side walls of 8 exert pressure on the first guide rod 201 and the second guide rod 206 inside the hole; as the bolt tightening increases, the pressure gradually increases, eventually clamping the first guide rod 201 and the second guide rod 206 firmly into the first vertical hole 203 and the second vertical hole 208; by applying pressure through the bolts, the connecting seat generates a clamping force on the guide rod, which can effectively prevent the guide rod from loosening or shifting during operation, ensuring the stability of the vertical support structure and providing reliable support for the smooth up and down sliding of the first adjustment frame.

[0053] Specifically, the first adjusting frame includes a third connecting seat 302, a fourth connecting seat 309, and a third guide rod 301; the third connecting seat 302 has a third vertical hole 303, and the third connecting seat 302 is sleeved on the first guide rod 201 through the third vertical hole 303; the fourth connecting seat 309 has a fourth vertical hole 310, and the fourth connecting seat 309 is sleeved on the second guide rod 206 through the fourth vertical hole 310; the third connecting seat 302 has a first horizontal hole 306, and the fourth connecting seat 309 has a second horizontal hole 313, and the third guide rod 301 is transversely inserted into the first horizontal hole 306 and the second horizontal hole 313; one end of the second adjusting frame is slidably connected to the third guide rod 301, and the second adjusting frame slides along the horizontal direction of the third guide rod 301.

[0054] The diameter of the third vertical hole 303 is tightly fitted to the outer diameter of the first guide rod 201, with tolerances controlled within a very small range, to ensure that the third connecting seat 302 can slide smoothly and stably up and down along the first guide rod 201; similarly, the fourth vertical hole 310 on the fourth connecting seat 309 is also tightly fitted to the outer diameter of the second guide rod 206. The first transverse hole 306 and the second transverse hole 313 are coaxial, and the diameter of the third guide rod 301 is determined according to the dimensions of the first transverse hole 306 and the second transverse hole 313, ensuring that it can be tightly inserted into the two holes to achieve a stable connection;

[0055] When the vertical position of the first adjustment frame needs to be adjusted, a vertical force can be applied to the first adjustment frame by manual force or an external driving device. Since the third connecting seat 302 and the fourth connecting seat 309 are respectively fitted on the first guide rod 201 and the second guide rod 206, the first adjustment frame can move smoothly up and down along these two guide rods. The third guide rod 301 serves as the track for the horizontal sliding of the second adjustment frame. When the horizontal position of the second adjustment frame needs to be adjusted, the second adjustment frame can slide freely along the third guide rod 301 to achieve precise horizontal positioning. This design enables the positioning device to have flexible adjustment capabilities in both the vertical and horizontal directions, and can quickly and accurately adjust the position of the detection component according to the position changes of the pusher 600 under different working conditions.

[0056] Specifically, the third connecting seat 302 has a third groove 304, which communicates with the third vertical hole 303; the third connecting seat 302 has a third locking hole that penetrates the third groove 304, and a third locking bolt 305 passes through the third locking hole; the third connecting seat 302 has a fourth groove 307, which communicates with the first transverse hole 306; the third connecting seat 302 has a fourth locking hole that penetrates the fourth groove 307, and a fourth locking bolt 308 passes through the fourth locking hole;

[0057] The fourth connecting seat 309 has a fifth groove 311, which communicates with the fourth vertical hole 310; the fourth connecting seat 309 has a fifth locking hole that penetrates the fifth groove 311, and a fifth locking bolt 312 passes through the fifth locking hole; the fourth connecting seat 309 has a sixth groove 314 that communicates with the second transverse hole 313; the fourth connecting seat 309 has a sixth locking hole that penetrates the sixth groove 314, and a sixth locking bolt 315 passes through the sixth locking hole.

[0058] When it is necessary to fix the position of the first adjusting bracket on the first guide rod 201 and the second guide rod 206, the third locking bolt 305 and the fifth locking bolt 312 are gradually tightened with a wrench. As the bolts are tightened, the bolt nuts apply pressure to the connecting seat portions on both sides of the third groove 304 and the fifth groove 311, causing these two portions to gradually move closer together. Since the third groove 304 is connected to the third vertical hole 303 and the fifth groove 311 is connected to the fourth vertical hole 310, this moving together action will cause the side walls of the third vertical hole 303 and the fourth vertical hole 310 to exert pressure on the first guide rod 201 and the second guide rod 206 inside the holes. As the bolts are tightened more deeply, this pressure increases continuously, and finally the first adjusting bracket is firmly fixed on the first guide rod 201 and the second guide rod 206.

[0059] The tightening force of the bolts compresses the connecting seat, thus tightly gripping the guide rod and effectively preventing displacement of the first adjusting frame during operation. This ensures the accuracy of the detection component's vertical position and meets the high-precision requirements of the positioning device. When it is necessary to adjust the vertical position of the first adjusting frame, simply loosen the third locking bolt 305 and the fifth locking bolt 312. The first adjusting frame can then slide freely on the first guide rod 201 and the second guide rod 206, achieving flexible adjustment of the first adjusting frame in the vertical direction.

[0060] Similarly, by tightening the fourth locking bolt 308 and the sixth locking bolt 315, pressure can be applied to the connecting seat portions on both sides of the fourth groove 307 and the fifth groove 311, causing these two portions to gradually move closer together. Since the fourth groove 307 is connected to the first transverse hole 306 and the sixth groove 314 is connected to the second transverse hole 313, this moving together action will cause the side walls of the first transverse hole 306 and the second transverse hole 313 to exert pressure on the third guide rod 301 inside the hole. As the bolts are tightened more deeply, this pressure increases continuously, eventually fixing the third guide rod 301 firmly inside the first transverse hole 306 and the second transverse hole 313. By tightening the fourth locking bolt 308 and the sixth locking bolt 315, the third guide rod 301 is firmly fixed inside the first transverse hole 306 and the second transverse hole 313, achieving a stable connection.

[0061] Specifically, the second adjustment frame includes a fifth connecting seat 402 and a fourth guide rod 401; the fifth connecting seat 402 has a third transverse hole 403, and the fifth connecting seat 402 is sleeved on the third guide rod 301 through the third transverse hole 403; the fifth connecting seat 402 has a fourth transverse hole 406 in the orthogonal direction of the third transverse hole 403, one end of the fourth guide rod 401 passes through the fourth transverse hole 406, and the detection component is disposed at the other end of the fourth guide rod 401.

[0062] The second adjustment frame is composed of a fifth connecting seat 402 and a fourth guide rod 401. The fifth connecting seat 402 is provided with a third transverse hole 403 and is sleeved on the third guide rod 301 through the third transverse hole 403 so as to slide along it. The fifth connecting seat 402 is provided with a fourth transverse hole 406 in a direction orthogonal to the third transverse hole 403. One end of the fourth guide rod 401 passes through the hole, and the other end is equipped with a detection component.

[0063] When the position of the detection component in the X direction needs to be adjusted, simply push the fifth connecting seat 402 to slide it along the third guide rod 301 to the appropriate position. To adjust the position of the detection component in the Y direction, the insertion depth of the fourth guide rod 401 in the fourth transverse hole 406 can be changed. Since the detection component is firmly fixed to the other end of the fourth guide rod 401, the position of the detection component in the Y direction will change accordingly as the insertion depth of the fourth guide rod 401 changes. Through the coordinated cooperation between the fifth connecting seat 402, the third guide rod 301, and the fourth guide rod 401, the detection component has flexible adjustment capabilities in both the X and Y directions, and can more accurately adjust its position according to the complex and ever-changing position of the pusher 600 under different working conditions.

[0064] Specifically, the fifth connecting seat 402 has a seventh groove 404, which communicates with the third transverse hole 403; the fifth connecting seat 402 has a seventh locking hole that passes through the seventh groove 404, and a seventh locking bolt 405 passes through the seventh locking hole.

[0065] The fifth connecting seat 402 has an eighth groove 407, which communicates with the fourth transverse hole 406; the fifth connecting seat 402 has an eighth locking hole that passes through the eighth groove 407, and an eighth locking bolt 408 passes through the eighth locking hole.

[0066] When it is necessary to fix the second adjustment bracket to the third guide rod 301, tighten the seventh locking bolt 405. As the bolt is tightened, the bolt nut applies pressure to the fifth connecting seat 402 on both sides of the seventh groove 404, causing the two sides of the seventh groove 404 to move closer to the middle. Since the seventh groove 404 is connected to the third transverse hole 403, this tendency to move closer will cause the two side walls of the third transverse hole 403 to exert pressure on the third guide rod 301 inside the hole. As the degree of bolt tightening increases, this pressure continues to increase, eventually fixing the fifth connecting seat 402 firmly to the third guide rod 301.

[0067] When it is necessary to fix the fourth guide rod 401 in the fourth transverse hole 406, tighten the eighth locking bolt 408. As the bolt is tightened, the bolt nut applies pressure to the fifth connecting seat 402 on both sides of the eighth groove 407, causing the two sides of the eighth groove 407 to move closer to the middle, thereby causing the two side walls of the fourth transverse hole 406 to exert pressure on the fourth guide rod 401 in the hole, and firmly fixing the fourth guide rod 401 to the fifth connecting seat 402.

[0068] The pressure applied by the bolts ensures that the connecting seat tightly grips the guide rod, effectively preventing displacement of the second adjusting frame and the fourth guide rod 401 during operation. This provides a stable and reliable mounting base for the detection components, meeting the stringent requirements of the positioning device for high-precision detection. Furthermore, when it is necessary to adjust the position of the second adjusting frame on the third guide rod 301, or change the position of the fourth guide rod 401 in the fourth transverse hole 406 of the fifth connecting seat 402, the position can be easily adjusted by simply loosening the seventh locking bolt 405 or the eighth locking bolt 408. After adjusting to the appropriate position, tighten the bolts again to complete the fixation.

[0069] Specifically, the detection component includes a mounting base 501 with a first mounting hole, and a fourth guide rod 401 with a second mounting hole. A mounting bolt is provided in the second mounting hole, and the mounting bolt passes through the first mounting hole and is threadedly connected to the second mounting hole to fix the mounting base 501 and the fourth guide rod 401 together. A proximity switch 502 is provided on the mounting base 501, and the proximity switch 502 is used to detect the position of the push flag 600.

[0070] When it is necessary to adjust the tilt angle of proximity switch 502, the fourth guide rod 401 can be rotated. Since the fourth guide rod 401 can rotate around the axis of the fourth transverse hole 406, it can drive the mounting base 501 connected to the fourth guide rod 401 to rotate together, thereby changing the tilt angle of proximity switch 502. For example, when the position of push flag 600 changes at a certain angle in the vertical direction during its movement, by rotating the fourth guide rod 401, the mounting base 501 and proximity switch 502 can be adjusted to a suitable tilt angle.

[0071] When it is necessary to adjust the horizontal rotation angle of the proximity switch 502, the mounting bolts connecting the mounting base 501 and the fourth guide rod 401 can be loosened, the mounting base 501 can be rotated, and the rotation angle of the mounting base 501 relative to the fourth guide rod 401 can be changed, thereby adjusting the rotation angle of the proximity switch 502; so that the proximity switch 502 can be better aligned with the push flag 600 at different positions in the horizontal direction, further improving the detection accuracy.

[0072] By flexibly adjusting the tilt angle and horizontal rotation angle of the proximity switch 502, the position of the detection component can be adjusted more precisely to adapt to the complex position changes of the push flag 600 under different working conditions, greatly improving the positioning accuracy of the push flag 600.

[0073] Specifically, the surfaces of the third guide rod 301, the fourth guide rod 401, and the first guide rod 201 are all provided with scale lines.
