Deviation measuring mechanism and conveyor belt

Abstract

This application discloses a deviation measuring mechanism and a material conveying device. The material conveying device forms a thick section and at least one thin section. The deviation measuring mechanism includes a mounting frame, a triggering member, and a detection member. The detection member sequentially forms a substandard detection area, a standard detection area, and an over-standard detection area along the thickness direction of the material conveying device. When the triggering member comes into contact with the thin section, it is pushed by the thin section so that at least part of it is placed in the substandard detection area and outside the standard detection area. The triggering member can come into contact with the thick section and be pushed by the thick section so that at least part of it moves from the substandard detection area to the standard detection area and is outside the over-standard detection area. The triggering member can be further pushed by the thick section it comes into contact with so that at least part of it moves from the standard detection area to the over-standard detection area. When the detection member detects that at least part of the triggering member is placed in the substandard detection area and outside the standard detection area or at least part of it is placed in the over-standard detection area, it generates a corresponding deviation correction signal.

Description

Technical Field

[0001] This application relates to the field of belt deviation correction technology, and in particular to deviation measuring mechanisms and belt conveying devices. Background Technology

[0002] Before being wound up, a protective film is applied to the surface of the sheet to prevent contamination, oxidation, or scratches, forming a strip. The width of the protective film is usually greater than the width of the sheet to protect it. This results in the strip having a thick section consisting of the sheet and the protective film combined, and a thin section consisting only of the protective film, in the width direction.

[0003] The material strip is usually conveyed by take-up and untake-up rollers, and deviations often occur during the conveying process. In order to correct the deviation in time, detection equipment is usually used to detect the position of the material strip in real time.

[0004] When using detection equipment to detect the position of the material strip, since the original protective film is mostly made of transparent material, a groove-shaped photoelectric sensor is generally used. The groove-shaped photoelectric sensor has a U-shaped groove structure, with the transmitter and receiver installed on both sides of the groove. The transmitter emits a light beam to the receiver, and the material strip continuously passes through the optical path channel in the groove during the conveying process. When the tape is in the standard conveying position, the edges of the thick and thin tape sections cover the beam area of ​​the transmitter in a predetermined proportion. The beam emitted by the transmitter is partially directed towards the thin tape section and partially towards the thick tape section. The beam directed towards the thin tape section passes through the thin tape section and is received by the receiver. At this time, the ratio of the actual light received by the receiver to the total light emitted by the transmitter remains within a preset threshold range, and the photoelectric sensor determines that the tape has not shifted. When the tape shifts into the groove, the coverage area of ​​the thin tape section in the beam area increases, and more beams pass through the thin tape section and are received by the receiver. At this time, the ratio of received light is higher than the upper limit of the preset threshold, and the photoelectric sensor determines that the tape has shifted inward. When the tape shifts outward from the groove, the coverage area of ​​the thick tape section in the beam area increases, and more beams are blocked by the thick tape section. The amount of light received by the receiver decreases, and the ratio of received light is lower than the lower limit of the preset threshold, and the photoelectric sensor determines that the tape has shifted outward.

[0005] In this design, if the strip is offset too far inward, the end of the thin strip that is far from the thick strip will rub against the groove wall of the groove in the depth direction of the groove-shaped photoelectric sensor, which may damage the groove-shaped photoelectric sensor.

[0006] Furthermore, to achieve data reuse, the protective film is recycled. During the process of peeling off the protective film, impurities may remain on the surface, which are difficult to completely remove. During the melt granulation regeneration process, the remaining impurities undergo carbonization or oxidation reactions when heated, causing the protective film obtained in subsequent production to yellow or even darken in color. This will result in the light beam not being able to effectively pass through the thin strip and be received by the transmitter during subsequent strip position detection, even if the thin strip is aligned with the transmitter, thus affecting the detection accuracy. Summary of the Invention

[0007] To solve the aforementioned technical problems and achieve at least one advantage of this application, this application provides a deviation measuring mechanism for detecting the position of a strip, wherein the strip has a thick portion and at least one thin portion formed on one side of the thick portion in the width direction, wherein the thickness of the thick portion is greater than the thickness of the thin portion, and the deviation measuring mechanism is held on one side of the edge in the width direction of the strip, the deviation measuring mechanism comprising:

[0008] Mounting rack;

[0009] A triggering member is configured to be movable, and the material strip is conveyed outside the triggering member such that its surface faces the triggering member and abuts against or separates from the triggering member;

[0010] The detection component, including both the triggering component and the detection component, is mounted on the mounting frame. The triggering component and the detection component are disposed on the same side and maintained along the thickness direction of the strip. The detection component sequentially forms a substandard detection area, a compliant detection area, and an excessive detection area along the thickness direction of the strip. The substandard detection area is closest to the strip. When the triggering component comes into contact with the thin strip portion, it is pushed by the thin strip portion to place at least partially within the substandard detection area and outside the compliant detection area. The triggering component can also come into contact with the thick strip portion and be pushed by the thick strip portion to move at least partially from the substandard detection area to the compliant detection area and outside the excessive detection area. The triggering component can be further pushed by the thick strip portion it comes into contact with to move at least partially from the compliant detection area to the excessive detection area. When the detection component detects that the triggering component is at least partially within the substandard detection area and outside the compliant detection area, or at least partially within the excessive detection area, it generates a corresponding correction signal.

[0011] According to one embodiment of this application, the detection component includes a detection assembly, which includes a signal transmitter and a signal receiver. The signal transmitter and the signal receiver are arranged at a distance from each other. The signal transmitter is configured to transmit a signal toward the signal receiver to form the non-compliant detection area, the compliant detection area, and the exceeding detection area between them. At least a portion of the signal emitted by the signal transmitter toward the signal receiver is blocked by the triggering member to prevent it from being received by the signal receiver. When at least a portion of the signal located in the non-compliant detection area and outside the compliant detection area, or at least a portion of the signal located in the exceeding detection area, is blocked by the triggering member, the signal receiver generates a corresponding correction signal.

[0012] According to one embodiment of this application, the triggering member includes a triggering assembly, which includes a moving member, a contact member, and a triggering element. The moving member is movably mounted on the mounting frame along the thickness direction of the strip. The contact member and the triggering element are both mounted on the moving member. The contact member is pushed by abutting against the thick strip portion or the thin strip portion, so that the triggering assembly moves along the thickness direction of the strip. The triggering element is located between the signal transmitter and the signal receiver. The triggering element blocks the signal receiver from receiving the corresponding portion of the signal by being at least partially placed in the non-compliance detection area and outside the compliance detection area or at least partially placed in the excess detection area, so that the signal receiver forms a corresponding correction signal.

[0013] According to one embodiment of this application, the contact member is rotatably mounted on the movable member, and the axial direction of the contact member is parallel to the width direction of the strip.

[0014] According to one embodiment of this application, the contact member includes a tapered portion. Along the width direction of the strip from the thick strip portion to the thin strip portion, the cross-sectional size of the tapered portion on the same side as the thin strip portion gradually increases. The tapered portion abuts against the thin strip portion and is pushed by the thin strip portion, so that the trigger member is at least partially located in the non-compliant detection area and outside the compliant detection area. The tapered portion can abut against the thick strip portion and be pushed by the thick strip portion, so that the trigger member is at least partially moved from the non-compliant detection area to the compliant detection area and outside the non-compliant detection area. The tapered portion can be further pushed by the thick strip portion it abuts against, so that the trigger member is at least partially moved from the compliant detection area to the non-compliant detection area.

[0015] According to one embodiment of this application, the contact member further includes a cylindrical portion formed by extending axially from the end with the largest cross-sectional size of the tapered portion, so that when the thick strip portion or the thin strip portion abuts against the end with the largest cross-sectional size of the tapered portion, it also abuts against the cylindrical portion.

[0016] According to one embodiment of this application, the triggering member includes an elastic element, the two ends of which are respectively connected to the moving member and the mounting bracket. When the moving member is pushed and moved by the thick strip portion or the thin strip portion, the elastic element undergoes elastic deformation, and the triggering component is held pressed against the thick strip portion or the thin strip portion of the material strip by the elastic force of the elastic element. When the material strip moves in the direction of decreasing cross-sectional size of the tapered portion, the triggering component moves in the opposite direction by the elastic force of the elastic element.

[0017] According to one embodiment of this application, the detection component includes a connecting frame, the signal transmitter and the signal receiver are mounted on the connecting frame at relative intervals, the connecting frame is mounted on the mounting frame, the detection component includes a mounting assembly, the mounting assembly includes a tightening member, the connecting frame has an oblong hole, the length direction of the oblong hole is parallel to the movement direction of the triggering component, the mounting frame has a threaded hole corresponding to the oblong hole, the tightening member is assembled on the mounting frame such that it passes through the oblong hole and is threaded into the threaded hole, and one end of the tightening member away from the mounting frame abuts against the connecting frame, after the tightening member is rotated to move in the direction extending from the threaded hole to the oblong hole, the connecting frame can move outside the tightening member in a direction parallel to the movement direction of the triggering component to adjust the distance between the detection component and the contact member in a direction parallel to the movement direction of the triggering component.

[0018] According to one embodiment of this application, the deviation measuring mechanism further includes a mating roller, which is mounted on the mounting frame and disposed opposite to the contact member of the triggering member. The material strip is conveyed in a manner that it is attached to the mating roller, and the minimum distance between the mating roller and the contact member is less than the thickness of the thin strip portion.

[0019] To solve the above-mentioned technical problems and achieve at least one advantage of this application, this application provides a material conveying device, the material conveying device comprising:

[0020] Deviation measuring mechanism;

[0021] The material rack includes a base and a rack body, and the deviation measuring mechanism is mounted on the base;

[0022] A material roller mechanism, the material roller mechanism including a material roller component, the material roller component being rotatably mounted on the frame body;

[0023] A correction mechanism, wherein the frame body is connected to the correction mechanism, and the frame body is mounted on the base in such a way that it can be driven by the correction mechanism to move relative to the base in a direction parallel to the axial direction of the material roller;

[0024] The controller is connected in communication with the detection component of the deviation measuring mechanism, and the deviation correction mechanism is controllably connected to the controller. The controller controls the operation of the deviation correction mechanism according to the corresponding deviation correction signal generated by the detection component.

[0025] The beneficial effects of this application include:

[0026] 1. This application converts the offset of the material strip into a positional change of the triggering member. By detecting the triggering member through the detection member, the offset of the material strip in the width direction can be detected. Compared with the detection method of directly emitting a light beam to the material strip, this method effectively avoids interference with the detection results due to changes in light transmittance caused by color changes in the thin strip, thus ensuring detection accuracy and preventing the detection member from being scratched.

[0027] 2. This application adjusts the distance between the detection component and the contact member in a direction parallel to the moving direction of the trigger component to satisfy the position detection of the strips with different thicknesses in the thick strip section.

[0028] 3. This application can automatically correct the deviation of the material sheet when it is offset.

[0029] 4. This application can adjust the position of the measuring mechanism in a direction parallel to the width direction of the strip, so that when the local thickness of the thin strip portion is greater than the thickness of the thick strip portion due to processing errors, the measuring mechanism can be moved to avoid damage.

[0048] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0049] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0050] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0051] refer to Figure 1 A preferred embodiment of the material conveying device according to this application will be described in detail below. The material conveying device includes a deviation measuring mechanism 10 for detecting the position of a material belt 90. The material belt 90 has a thick strip portion 91 and at least one thin strip portion 92 formed on one side of the thick strip portion 91 in the width direction, wherein the thickness of the thick strip portion 91 is greater than the thickness of the thin strip portion 92.

[0052] refer to Figures 1 to 6The deviation measuring mechanism 10 is held on one side of the edge in the width direction of the strip 90. The deviation measuring mechanism 10 includes a mounting frame 11, a triggering member 12, and a detection member 13. The triggering member 12 and the detection member 13 are both mounted on the mounting frame 11. The triggering member 12 and the detection member 13 are arranged on the same side and are both held in the thickness direction of the strip 90. The triggering member 12 is movable. The strip 90 is conveyed outside the triggering member 12 with its surface facing and abutting against the triggering member 12. The detection member 13 sequentially forms a substandard detection area A, a standard detection area B, and an excessive detection area C along the thickness direction of the strip 90, wherein the substandard detection area A is closest to the strip 90. The trigger member 12, upon contact with the thin strip portion 92, is pushed by the thin strip portion 92 to place it at least partially outside the substandard detection area A and the compliant detection area B; the trigger member 12 can contact the thick strip portion 91 and be pushed by the thick strip portion 91 to move it at least partially from the substandard detection area A to the compliant detection area B and outside the exceeding detection area C; the trigger member 12 can be further pushed by the thick strip portion 91 it contacts to move it at least partially from the compliant detection area B to the exceeding detection area C. The detection member 13 generates a corresponding correction signal when it detects that the trigger member 12 is at least partially placed in the substandard detection area A and outside the compliant detection area B, or at least partially placed in the exceeding detection area C.

[0053] In this process, the offset of the strip 90 is converted into a positional change of the trigger member 12. The detection member 13 detects the trigger member 12, thereby detecting the offset of the strip 90 in the width direction. Those skilled in the art will understand that, compared to detection methods that directly emit a light beam onto the strip 90, this method effectively avoids interference with the detection results due to changes in light transmittance caused by color changes in the thin strip portion 92, ensuring detection accuracy and preventing any scraping of the detection member 13.

[0054] In one embodiment, the detection component 13 includes a detection assembly 131, which includes a signal transmitter 1311 and a signal receiver 1312. The signal transmitter 1311 and the signal receiver 1312 are disposed at a distance from each other. The signal transmitter 1311 is configured to transmit a signal toward the signal receiver 1312 to form the non-compliance detection area A, the compliance detection area B, and the excess detection area C between them. At least a portion of the signal emitted by the signal transmitter 1311 toward the signal receiver 1312 is blocked by the triggering member 12 to prevent it from being received by the signal receiver 1312. When at least a portion of the signal located in the non-compliance detection area A and outside the compliance detection area B, or at least a portion of the signal located in the excess detection area C, is blocked by the triggering member 12, the signal receiver 1312 generates a corresponding correction signal.

[0055] Preferably, the detection component 13 is implemented using, but is not limited to, photoelectric sensors and acoustic sensors. Based on the configuration of the trigger component 12, compared to existing technologies, it is not limited to photoelectric sensors.

[0056] refer to Figures 3 to 7 Furthermore, the triggering member 12 includes a triggering assembly 121, which includes a moving member 1211, a contact member 1212, and a triggering member 1213. The moving member 1211 is movably mounted on the mounting frame 11 along the thickness direction of the strip 90. The contact member 1212 and the triggering member 1213 are both mounted on the moving member 1211. The contact member 1212 is pushed by abutting against the thick strip portion 91 or the thin strip portion 92, so that the triggering assembly 121 moves along the thickness direction of the strip 90. The triggering member 1213 is located between the signal transmitter 1311 and the signal receiver 1312. The triggering member 1213 blocks the signal receiver 1312 from receiving the corresponding portion of the signal by being at least partially placed in the non-compliance detection area A and outside the compliance detection area B, or at least partially placed in the excess detection area C, so that the signal receiver 1312 generates a corresponding correction signal.

[0057] Preferably, the contact member 1212 is rotatably mounted on the moving member 1211, and the axial direction of the contact member 1212 is parallel to the width direction of the material strip 90, so as to generate rolling friction when the material strip 90 contacts the contact member 1212, effectively preventing the material strip 90 from being worn.

[0058] In one embodiment, the contact member 1212 includes a tapered portion 12121. Along the width direction of the strip 90, from the thicker strip portion 91 to the thinner strip portion 92, the cross-sectional dimension of the tapered portion 12121 on the same side as the thinner strip portion 92 gradually increases. This design of the tapered portion 12121 provides a smooth transition, allowing the strip 90 to move along the direction of increasing cross-sectional dimension of the tapered portion 12121, based on the uneven thickness of the strip 90, so that the thicker strip portion 91 or the thinner strip portion 92 corresponds to and abuts against the end of the tapered portion 12121 with the largest cross-sectional dimension. The tapered portion 12121 abuts against and is pushed by the thin strip portion 92, so that the trigger 1213 is at least partially located outside the non-compliant detection area A and outside the compliant detection area B; the tapered portion 12121 can abut against and be pushed by the thick strip portion 91, so that the trigger 1213 is at least partially moved from the non-compliant detection area A to the compliant detection area B and outside the non-compliant detection area C; the tapered portion 12121 can be further pushed by the thick strip portion 91 it abuts against, so that the trigger 1213 is at least partially moved from the compliant detection area B to the non-compliant detection area C.

[0059] More preferably, the contact member 1212 further includes a cylindrical portion 12122 extending axially from the end with the largest cross-sectional size of the tapered portion 12121, so that when the thick strip portion 91 or the thin strip portion 92 abuts against the end with the largest size of the tapered portion 12121, it also abuts against the cylindrical portion 12122. Compared with abutting only against the end with the largest size of the tapered portion 12121, the contact is changed from line contact to surface contact, effectively avoiding scratches on the surface of the thick strip portion 91 or the thin strip portion 92.

[0060] Further, the triggering member 12 includes an elastic element 122, with its two ends connected to the moving member 1211 and the mounting bracket 11, respectively. When the moving member 1211 is pushed and moved by the thick strip portion 91 or the thin strip portion 92, the elastic element 122 undergoes elastic deformation, and the triggering member 121 is held in place by the elastic force of the elastic element 122, pressed against the thick strip portion 91 or the thin strip portion 92 of the material strip 90. When the material strip 90 moves in a direction decreasing in cross-sectional size along the tapered portion 12121, the triggering member 121 moves in the opposite direction under the elastic force of the elastic element 122 to reset.

[0061] Preferably, the elastic element 122 is implemented as a spring.

[0062] Preferably, when the moving direction of the trigger component 121 is vertical, the trigger component 121 moves in the opposite direction under the action of gravity and the elastic force of the elastic member 122 when the material strip 90 moves along the direction of decreasing cross-sectional size of the tapered portion 12121, so that the trigger component 121 can quickly reset.

[0063] Furthermore, the detection component 13 includes a connecting frame 132, and the signal transmitter 1311 and the signal receiver 1312 are mounted on the connecting frame 132 at a relative interval, and the connecting frame 132 is mounted on the mounting frame 11.

[0064] refer to Figures 4 to 5 as well as Figure 7 Furthermore, the detection component 13 includes a mounting assembly 133, which includes a tightening member 1331. The connecting bracket 132 has an oblong hole 13201, the length direction of which is parallel to the moving direction of the trigger component 121. The mounting bracket 11 has a threaded hole 1101 corresponding to the oblong hole 13201. The tightening member 1331 assembles the connecting bracket 132 onto the mounting bracket 11 by passing through the oblong hole 13201 and being threaded into the threaded hole 1101, with one end of the tightening member away from the mounting bracket 11 abutting against the connecting bracket 132. Furthermore, after the tightening member 1331 is rotated to move in the direction extending from the threaded hole 1101 to the waist-shaped hole 13201, the connecting bracket 132 can move outside the tightening member 1331 in a direction parallel to the moving direction of the trigger assembly 121 to adjust the distance between the detection assembly 131 and the contact member 1212 in a direction parallel to the moving direction of the trigger assembly 121, so as to satisfy the position detection of the strips 90 with different thicknesses of the thick strip portion 91.

[0065] Those skilled in the art will understand that this application may also omit the oblong hole 13201, and instead provide a plurality of through holes spaced apart in a direction parallel to the moving direction of the trigger component 121 on the connecting bracket 132. The tightening member 1331 is used to assemble the connecting bracket 132 onto the mounting bracket 11 such that it passes through one of the through holes and is threadedly connected to the threaded hole 1101, and its end away from the mounting bracket 11 abuts against the connecting bracket 132. In addition, when the tightening member 1331 is rotated to move toward the threaded hole 1101 in a direction corresponding to the through hole to separate from the mounting bracket 11 and the connecting bracket 132, the connecting bracket 132 moves in a direction parallel to the moving direction of the trigger component 121 so that the through holes at different positions correspond to the threaded hole 1101. By installing the tightening member 1331, the distance between the detection component 131 and the contact member 1212 in a direction parallel to the moving direction of the trigger component 121 can be adjusted.

[0066] Furthermore, the mounting assembly 133 includes an abutment member 1332, which is threadedly connected to the connecting frame 132 with one end corresponding to the mounting bracket 11. The abutment member 1332 can rotate to abut or separate from the mounting bracket 11. When the moving direction of the trigger assembly 121 is vertical, the abutment member 1332 is positioned at the top of the mounting bracket 11, and the abutment member 1332 supports the connecting frame 132 by abutting against the mounting bracket 11.

[0067] refer to Figures 3 to 5 as well as Figure 7 Furthermore, the bias measuring mechanism 10 also includes a mating roller 14, which is mounted on the mounting frame 11 and is disposed opposite to the contact member 1212 of the triggering member 12. The material strip 90 is conveyed in a manner that it is attached to the mating roller 14. The minimum distance between the mating roller 14 and the contact member 1212 is less than the thickness of the thin strip portion 92, so that after the thin strip portion 92 or the thick strip portion 91 moves between the mating roller 14 and the contact member 1212, it can push the contact member 1212 to move along the thickness direction of the material strip 90.

[0068] Preferably, the mating roller 14 is rotatably mounted on the mounting frame 11, and the mating roller 14 and the contact member 1212 are axially parallel to each other so as to reduce the resistance when the material belt 90 is conveyed by rolling friction.

[0069] refer to Figures 1 to 2 as well as Figures 8 to 9Furthermore, the material conveying device includes a material rack 30 and a material roller mechanism 40. The material roller mechanism 40 includes a material roller member 41, which is rotatably mounted on the material rack 30. The material roller member 41 is axially parallel to the mating roller 14. The material strip 90 is wound around the material roller member 41 and conveyed to the surface of the mating roller 14. The material roller member 41 rotates to unwind or rewind the material strip 90.

[0070] Furthermore, the material roller mechanism 40 includes a drive assembly 42, which is mounted on the material rack 30. The material roller 41 is mounted on the drive assembly 42 and driven by the drive assembly 42 to rotate, so as to perform winding or unwinding actions.

[0071] Preferably, the drive assembly 42 is implemented to include a motor.

[0072] Further, the material rack 30 includes a base 31 and a frame body 32. The material roller mechanism 40 is mounted on the frame body 32, and the deviation measuring mechanism 10 is mounted on the base 31. The material belt conveying device includes a deviation correction mechanism 50 and a controller 60. The frame body 32 is connected to the deviation correction mechanism 50, and the frame body 32 is mounted on the base 31 in a manner that allows it to be driven by the deviation correction mechanism 50 to move relative to the base 31 in a direction parallel to the axial direction of the material roller 41. The signal receiver 1312 is communicatively connected to the controller 60, and the deviation correction mechanism 50 is controllably connected to the controller 60. The controller 60 controls the operation of the deviation correction mechanism 50 based on the deviation correction signal generated by the signal receiver 1312.

[0073] Specifically, when the tape 90 is conveyed and the thin tape portion 92 abuts against the contact member 1212, the trigger assembly 121 is pushed by the thin tape portion 92, causing the trigger member 1213 to be at least partially placed outside the non-compliance detection area A and outside the compliance detection area B. The signal emitted by the signal transmitter 1311 and located outside the area blocked by the trigger member 1213 is received by the signal receiver 1312. The signal receiver 1312 generates a corresponding correction signal and feeds it back to the controller 60. The controller 60 controls the operation of the correction mechanism 50, which drives the frame body 32 to move relative to the base 31 along the thick strip 91 in a direction parallel and in the same direction as the thin strip 92 on the same side as the measuring mechanism 10; when the material strip 90 is conveyed, the thick strip 91 abuts against the conical portion 12121 of the contact member 1212, and by pushing the contact member 1212, the trigger member 1213 is at least partially placed in the compliance detection area B and located in the excess detection area. When outside the detection area C, the signal emitted by the signal transmitter 1311 and located outside the area blocked by the trigger 1213 is received by the signal receiver 1312. The signal receiver 1312 feeds back to the controller 60, and the controller 60 controls the correction mechanism 50 to suspend operation. When the contact 1212 is further pushed by the thick strip portion 91 it abuts against, causing the trigger 1213 to move at least partially from the compliance detection area B to the non-compliance detection area C, the signal emitted by the signal transmitter 1311... Signals emitted and located outside the area blocked by the trigger 1213 are received by the signal receiver 1312. The signal receiver 1312 generates a corresponding correction signal and feeds it back to the controller 60. The controller 60 controls the operation of the correction mechanism 50. The correction mechanism 50 drives the frame body 32 to move relative to the base 31 in a direction parallel and in the same direction as the thin strip 92 on the same side as the deviation measuring mechanism 10, extending towards the thick strip 91, so as to realize automatic correction of the material strip 90 in the width direction.

[0074] Preferably, the correction mechanism 50 is implemented using, but is not limited to, a cylinder.

[0075] Furthermore, the material conveying device also includes a clearance mechanism 20, which includes a translation member 21. The translation member 21 is mounted on the base 31 of the material rack 30. The mounting frame 11 is connected to the base 31 via the translation member 21. The mounting frame 11 can be moved by the translation member 21 in a direction parallel to the width direction of the material strip 90, thereby adjusting the position of the deviation measuring mechanism 10 in the direction parallel to the width direction of the material strip 90. In this way, when the thickness of the thin strip portion 92 is locally greater than that of the thick strip portion 91 due to processing errors, the translation member 21 moves the deviation measuring mechanism 10 to clear the obstacle and prevent damage to the deviation measuring mechanism 10.

[0076] Preferably, the translation member 21 is implemented as a cylinder.

[0077] Furthermore, the avoidance mechanism 20 includes a thickness measuring component 22. The strip 90 is conveyed and passes through the thickness measuring component 22 before being guided to the deviation measuring mechanism 10. The thickness measuring component 22 is used to detect the thickness of the thin strip portion 92. The thickness measuring component 22 is communicatively connected to the controller 60, and the translation component 21 is controllably connected to the controller 60. When the thickness measuring component 22 detects that the thickness of the thin strip portion 92 is greater than the thickness of the thick strip portion 91, the translation component 21 is controlled by the controller 60 to move the deviation measuring mechanism 10 away from the strip 90 for automatic avoidance.

[0078] Preferably, the thickness measuring component 22 is implemented as a thickness sensor.

[0079] Preferably, the material roller 41 is configured to unwind the material strip 90, and the thickness measuring member 22 is placed between the material roller 41 and the deviation measuring mechanism 10. After the material strip 90 is unwound by the material roller 41, it is guided to the thickness measuring member 22 and then moves through the deviation measuring mechanism 10, so that the thickness measuring member 22 first detects the thickness of the thin strip 92, and then the controller 60 decides whether to control the deviation measuring mechanism 10 to move through the translation member 21 to avoid the obstacle.

[0080] Furthermore, the material conveying device includes a guide roller assembly 70, which includes a first guide roller 71. The first guide roller 71 is rotatably mounted on the base 31. The first guide roller 71 is adjacent to and axially parallel to the mating roller 14. The deviation measuring mechanism 10 is located between the material roller assembly 41 and the first guide roller 71. The material belt 90 is conveyed in a manner that it adheres to the surface of the first guide roller 71.

[0081] Furthermore, the guide roller group 70 includes a plurality of second guide rollers 72, which are rotatably mounted on the frame body 32. The second guide rollers 72 are axially parallel to the material roller 41, and the plurality of second guide rollers 72 are disposed between the material roller 41 and the mating roller 14. The material strip 90 is conveyed by wrapping around the plurality of second guide rollers 72.

[0082] This application also proposes a method for operating a belt conveyor, including the following steps:

[0083] When the material strip 90 is conveyed and the thin strip portion 92 comes into contact with the trigger member 12, the trigger member 12 is pushed by the thin strip portion 92 and is at least partially placed in the non-compliance detection area A and outside the compliance detection area B. At this time, the detection member 13 detects the deviation of the material strip 90 conveying trajectory and generates a corresponding correction signal.

[0084] When the material strip 90 is conveyed such that the thick strip portion 91 abuts against the trigger member 12 and pushes the trigger member 12, causing the trigger member 12 to move at least partially from the substandard detection area A to the standard detection area B and be located outside the substandard detection area C, the detection member 13 detects that the conveying trajectory of the material strip 90 meets the standard.

[0085] When the material belt 90 is conveyed and the trigger member 12 is abutted against the thick belt portion 91, and the trigger member 12 is at least partially moved from the compliance detection area B to the non-compliance detection area C, the detection member 13 detects the deviation of the material belt 90 conveying trajectory and generates a corresponding correction signal.

[0086] Preferably, the operating method of the material conveyor includes the following steps:

[0087] The contact 1212 is pushed by the thick strip 91 or the thin strip 92, causing the trigger assembly 121 to move relative to the mounting frame 11 along the thickness direction of the strip 90. The contact 1212 drives the trigger 1213 to move between the signal transmitter 1311 and the signal receiver 1312 through the moving member 1211, while the elastic member 122 undergoes elastic deformation.

[0088] Preferably, the operating method of the material conveyor includes the following steps:

[0089] The tightening member 1331 is rotated to move it toward the threaded hole 1101 in the direction extending toward the waist-shaped hole 13201, thereby removing the pressure applied to the connecting bracket 132 at one end away from the mounting bracket 11. At this time, the connecting bracket 132 can move outside the tightening member 1331 in a direction parallel to the moving direction of the trigger assembly 121 to adjust the distance between the detection assembly 131 and the contact member 1212 in a direction parallel to the moving direction of the trigger assembly 121, so as to satisfy the position detection of the strip 90 with different thicknesses of the thick strip portion 91.

[0090] Preferably, the operating method of the material conveyor includes the following steps:

[0091] The detection component 13 transmits the corresponding correction signal to the controller 60. When the thin strip 92 abuts against the trigger component 12, the controller 60 controls the correction mechanism 50 to operate. The correction mechanism 50 drives the frame body 32 to move relative to the base 31 along the thick strip 91 in a direction parallel and in the same direction as the extension direction of the thin strip 92 on the same side as the measuring mechanism 10. When the thick strip 91 abuts against the trigger component 12 and pushes the trigger component 12, causing the trigger component 12 to move at least partially from the compliance detection area B to the non-compliance detection area C, the controller 60 controls the correction mechanism 50 to operate. The correction mechanism 50 drives the frame body 32 to move relative to the base 31 along the direction parallel and in the same direction as the extension direction of the thin strip 92 on the same side as the measuring mechanism 10 to the extension direction of the thick strip 91, so as to realize automatic correction of the material strip 90 in the width direction.

[0092] Preferably, the operating method of the material conveyor includes the following steps:

[0093] The thickness measuring component 22 detects the thickness of the thin strip 92 and feeds it back to the controller 60. When the controller 60 determines that the thickness of the thin strip 92 is within a predetermined range, the controller 60 controls the translation component 21 to pause operation. When the controller 60 determines that the thickness of the thin strip 92 is greater than the thickness of the thick strip 91, the controller 60 controls the translation component 21 to run. The deviation measuring mechanism 10 is driven by the translation component 21 to slide in a direction parallel and in the same direction as the extension direction of the thick strip 91 toward the thin strip 92 on the same side as the deviation measuring mechanism 10, so as to avoid collision.
