Description

Technical Field

[0001] This invention relates to the field of detection technology, and in particular to a roller with a material belt skew detection function. Background Technology

[0002] In battery production, the material strip needs to be transported via a roller mechanism. As the strip passes through multiple different rollers, assembly precision errors between these rollers can easily lead to skewing and wrinkling. Existing rollers typically only provide support, such as fixing the roller at both ends with floating support seats. However, they cannot promptly detect and alert when the strip skewing causes the roller to also skew. Rollers with detection capabilities usually require additional detection and correction devices installed outside the roller itself, which is too costly. Therefore, a roller that can promptly detect and alert when the strip skewing occurs is needed. Summary of the Invention

[0003] This invention provides a conveyor roller with a conveyor belt skew detection function, which can promptly detect and alert when the conveyor belt becomes skewed after passing through the roller.

[0004] In a first aspect, embodiments of the present invention provide a feed roller with a strip skew detection function. The feed roller includes a feed roller body and a roller seat. The roller seat includes a first chamber. The feed roller body extends into the first chamber. A floating element and a sensing element are disposed in the first chamber. The first end of the floating element is floatingly connected to the roller seat, and the second end of the floating element abuts against the feed roller body. The sensing element is configured to detect the skew amount of the feed roller body when there is a relative displacement between the feed roller body and the roller seat.

[0005] Optionally, the roller seat also includes a second chamber that is partially connected to the first chamber. The first end of the floating member has an elastic portion, which is disposed in the second chamber. The elastic portion can contract or expand when the roller body applies a force to the floating member, so that the roller body can be offset relative to the roller seat.

[0006] Optionally, multiple sensors are arranged circumferentially around the outer edge of the roller body.

[0007] Optionally, the roller holder also includes a third chamber that is partially connected to the first chamber. The end of the sensing element near the roller body has a sensing part, which is disposed in the first chamber. The end of the sensing element away from the roller body is adjustablely disposed in the third chamber, so that the sensing part can be close to or away from the roller body.

[0008] Optionally, a turntable is provided on the side of the roller seat away from the roller body, and the end of the sensing element away from the roller body has a rod with a first tooth structure. The first surface of the turntable opposite to the sensing element has a second tooth structure, and the second tooth structure meshes with the first tooth structure of the rod.

[0009] Optionally, the second surface of the turntable away from the sensor is provided with a speed-changing gear set connected to the turntable. The speed-changing gear set can drive the turntable to rotate, thereby causing the rod of the sensor to rotate, so that the sensing part can move closer to or away from the roller body.

[0010] Optionally, the gear set includes a gear and a knob. The second surface has an annular protrusion around the center of the turntable. The knob is coaxially connected to the gear. A third tooth structure is provided on the periphery of the annular protrusion. The gear meshes with the third tooth structure.

[0011] Optionally, the first chamber of the roller seat is a hollow chamber.

[0012] Optionally, the roller seat also includes a first cover plate and a second cover plate. The first chamber has a first opening on the side near the roller body, and the first cover plate covers the first opening. The second chamber has a second opening on the side away from the roller body, and the second cover plate covers the second opening.

[0013] Optionally, roller seats are provided at both ends of the roller body.

[0014] The present invention relates to a roller guide that extends the roller body into the first chamber of the roller holder, and a floating element and a sensing element are installed in the first chamber of the roller holder. The floating element floats and supports the roller body, so that when the material belt passing through the roller is deviated, the roller body can also be offset relative to the roller holder. The sensing element is used to detect the amount of offset of the roller body relative to the roller holder. When the roller body is offset, the sensing element can detect the degree of deviation of the roller body and send the detection data outward to promptly remind the operator to correct the offset of the material belt and the roller.

[0029] The roller 100 of this embodiment includes a roller body 110 and a roller seat 120. The roller seat 120 includes a first chamber 121. The roller body 110 extends into the first chamber 121. A floating element 122 and a sensing element 123 are disposed in the first chamber 121. The first end of the floating element 122 is floatingly connected to the roller seat 120, and the second end of the floating element 122 abuts against the roller body 110. The sensing element 123 is configured to detect the amount of skewness of the roller body 110 when there is a relative displacement between the roller body 110 and the roller seat 120.

[0030] In this embodiment of the invention, the two ends of the roller body 110 of the roller 100 extend into the first chamber 121 of the roller seat 120, and the roller body 110 and the roller seat 120 are floatingly connected by the floating member 122 provided in the first chamber 121. When the material belt passing through the roller 100 deviates, the floating connection between the roller body 110 and the roller seat 120 allows the roller body 110 to deviate along with the material belt, so that the sensing member 123 located in the first chamber 121 can sense the relative displacement between the roller body 110 and the roller seat 120 and detect the amount of deviation of the roller body 110.

[0031] In this embodiment of the invention, the guide roller 100 extends the guide roller body 110 into the first chamber 121 of the roller seat 120, and a floating element 122 and a sensing element 123 are provided in the first chamber 121 of the roller seat 120. The floating element 122 floats and supports the guide roller body 110, so that when the material belt passing through the guide roller 100 is deviated, the guide roller body 110 can also be offset relative to the roller seat 120. The sensing element 123 is used to detect the amount of offset of the guide roller body 110 relative to the roller seat 120. When the guide roller body 110 is offset, the sensing element 123 can detect the degree of deviation of the guide roller body 110 and send the detection data outward to promptly remind the operator to correct the offset of the material belt and the guide roller 100.

[0032] Optionally, in this embodiment of the invention, the sensing element 123 and the roller body 110 are spaced apart, and the sensor provided in the sensing element 123 in this embodiment of the invention can be a pressure sensor, a laser sensor, a magnetic induction sensor, etc.

[0033] When the sensing element 123 detects the amount of skewness through the pressure sensor, if the material belt is skewed, the roller body 110 will also be skewed due to the skewed material belt. The roller body 110 and the roller seat 120 will be relatively displaced, and the roller body 110 will come into contact with the sensing element 123, applying pressure to the sensing element 123. The amount of skewness of the roller body 110 can be obtained by the pressure detected by the pressure sensor.

[0034] When the sensing element 123 detects the skew amount through the laser sensor or the magnetic induction sensor, if the roller body 110 and the roller seat 120 undergo relative displacement and the distance between the roller body 110 and the sensing element 123 changes, the sensing element can obtain the skew amount of the roller body 110 by detecting the change in distance through the laser sensor or by detecting the change in the magnetic field through the magnetic induction sensor.

[0035] Optionally, the roller holder 120 further includes a second chamber 124 that partially communicates with the first chamber 121. The first end of the floating member 122 has an elastic portion 1221, which is disposed within the second chamber 124. The elastic portion 1221 can contract or expand when the roller body 110 applies a force to the floating member 122, allowing the roller body 110 to shift relative to the roller holder 120. The end of the floating member 122 near the roller body 110 has an abutting portion 1222 that abuts against the circumferential surface of the roller body 110.

[0036] like Figure 3 , Figure 6 and Figure 7 As shown, in an embodiment of the present invention, the elastic portion 1221 of the floating member 122 is disposed in the second chamber 124, and the abutting portion 1222 of the floating member 122 is disposed in the first chamber 121. When the material belt deviates, the roller body 110 applies a force to the abutting portion 1222, causing the elastic portion 1221 to contract or expand within the second chamber 124. The roller body 110 also deviates slightly with the material belt to trigger the sensing element 123 to detect the amount of deviance of the roller body 110. By confining the elastic portion 1221 within the second chamber 124, the deviance of the roller body 110 is affected by the degree of contraction or expansion of the elastic portion 1221 within the second chamber 124, thereby controlling the degree of deviance of the roller body 110, and cooperating with the sensing element 123 to detect the amount of deviance of the roller body 110.

[0037] Meanwhile, the side of the abutting part that abuts against the roller body is an arc shape that matches the outer circumferential surface of the roller body, making the abutting between the floating part and the roller body more stable.

[0038] Furthermore, in this embodiment of the invention, the elastic part 1221 may be a piston, spring, etc. When the roller body 110 is subjected to the force generated by the skew of the incoming material belt, the elastic part 1221 can contract or expand, so that the roller body 110 can be offset relative to the roller seat 120.

[0039] like Figure 3 As shown, optionally, a plurality of sensing elements 123 are arranged circumferentially around the outer edge of the roller body 110.

[0040] Specifically, in this embodiment of the invention, four sensing elements 123 and four floating elements 122 are respectively arranged radially along the roller body 110 within the roller holder 120. Each floating element 122 and each sensing element 123 are arranged in a group and side by side. The floating elements 122 are located within the roller holder 120 near the roller body 110, and the sensing elements 123 are located within the roller holder 120 away from the roller body 110. Each group of floating elements 122 and sensing elements 123 within the roller holder 120 are evenly spaced. When the material belt deviates, the direction of deviation of the roller body 110 caused by the influence of the material belt is difficult to determine. By arranging the sensing elements and floating elements in groups around the roller body, with each group spaced 90° apart, the sensing elements within the roller holder 120 can accurately detect the deviation of the roller body 110 in different directions.

[0041] Optionally, the roller holder 120 further includes a third chamber 125 that is partially connected to the first chamber 121. The end of the sensing element 123 near the roller body 110 has a sensing part 1232, which is disposed in the first chamber 121. The end of the sensing element 123 away from the roller body 110 is adjustablely disposed in the third chamber 125, so that the sensing part 1232 can be close to or away from the roller body 110.

[0042] like Figure 3 , Figure 6 and Figure 7 As shown, in an embodiment of the present invention, there is a cavity between the sensing unit 1232 disposed in the first chamber and the roller body 110. When the material belt is deflected, the cavity between the sensing unit 1232 and the roller body 110 will increase or decrease as the roller body 110 deflects, and the distance between the sensing unit 1232 and the roller body 110 will change, thereby triggering the sensing unit 1232 to detect the amount of deflection of the roller body 110.

[0043] Meanwhile, since the end of the sensing element 123 furthest from the roller body 110 is adjustablely disposed in the third chamber 125, the size of the cavity between the sensing part 1232 and the roller body 110 can be adjusted by adjusting the position of the end of the sensing element 123 in the third chamber 125. When the cavity between the sensing part 1232 and the roller body 110 becomes smaller, the detection accuracy of the sensing part 1232 in detecting the skewness of the material strip and the roller body 110 becomes higher; when the cavity between the sensing part 1232 and the roller body 110 becomes larger, the detection accuracy of the sensing part 1232 in detecting the skewness of the material strip and the roller body 110 becomes lower. By adjusting the size of the cavity between the sensing part 1232 and the roller body 110, the roller 100 of the embodiment of the present invention can detect the skewness of material strips of different types and widths.

[0044] Optionally, a turntable 130 is provided on the side of the roller seat 120 away from the roller body 110, and the end of the sensing element 123 away from the roller body 110 has a rod portion 1231 with a first tooth structure. The first surface 131 of the turntable 130 opposite to the sensing element 123 has a second tooth structure, and the second tooth structure meshes with the first tooth structure of the rod portion 1231.

[0045] In an embodiment of the present invention, the second toothed structure of the turntable 130 meshes with the first toothed structure of the rod portion 1231 of a plurality of sensors 123 in the third chamber 125. When the turntable 130 rotates, it can drive the rod portion 1231 of the plurality of sensors 123 in the roller seat 120 to rotate through the meshing structure. The rotating rod portion 1231 can drive the sensing portion 1232 to move along the axial direction of the rod portion 1231 in the first chamber 121. By adjusting the rotation direction of the turntable 130, the sensing portion 1232 of the sensor 123 can be controlled to move away from or closer to the roller body 110, so as to adjust the detection accuracy of the sensor 123.

[0046] like Figure 4 and Figure 6 As shown, in the first embodiment of the present invention, a bearing 126 is sleeved between the first toothed structure of the rod 1231 and the sensing element 123. The bearing 126 is disposed at the communication between the first chamber 121 and the third chamber 125 of the roller seat 120, so that the rod 1231 is fixed in the roller seat 120. The sensing element 1232 is threadedly connected to the rod 1231. When the turntable 130 drives the rod 1231 to rotate, the rotating rod 1231 can drive the sensing element 1232 to move along the axial direction of the rod 1231, so that the sensing element 1232 can move closer to or further away from the roller body 110.

[0047] like Figure 5 and Figure 7As shown, in the second embodiment of the present invention, the end face of the rod 1231 away from the sensing part 1232 is rotatably connected to the inner wall of the roller seat 120 via a rotating shaft 127, so that the rod 1231 is fixed inside the roller seat 120. The sensing part 1232 and the rod 1231 are connected by a thread. When the turntable 130 drives the rod 1231 to rotate, the rotating rod 1231 can drive the sensing part 1232 to move along the axial direction of the rod 1231, so that the sensing part 1232 can move closer to or away from the roller body 110.

[0048] Optionally, the second surface 132 of the turntable 130 away from the sensing element 123 is provided with a speed-changing gear set connected to the turntable 130. The speed-changing gear set can drive the turntable 130 to rotate, thereby causing the rod portion 1231 of the sensing element 123 to rotate, so that the sensing portion 1232 can approach or move away from the roller body 110.

[0049] The speed-changing gear set drives the turntable 130 to rotate by meshing with the second surface 132 of the turntable 130, so that the turntable 130 can drive the rods 1231 of the multiple sensors 123 located in the roller seat 120 to rotate.

[0050] Furthermore, the gear set includes a gear 140 and a knob 150. The second surface 132 has an annular protrusion 133 surrounding the center of the turntable 130. The knob 150 is coaxially connected to the gear 140. A third tooth structure is provided on the periphery of the annular protrusion 133, and the gear 140 meshes with the third tooth structure.

[0051] By turning the knob 150, the gear 140 rotates to drive the turntable 130 to rotate. The rotating turntable 130 drives the rods 1231 of the multiple sensors 123 meshing with it to rotate, causing the sensing parts 1232 of the sensors 123 to move away from or closer to the roller body 110 along the radial direction of the roller body 110. The distance between the sensing parts 1232 and the roller body 110 increases or decreases. The roller 100 of this embodiment can adjust the detection accuracy of the sensors 123 for the skewness of the roller body 110 by controlling the distance between the sensing parts 1232 and the roller body 110. By setting the sensors 123 in the roller seat 120, the roller 100 of this embodiment can detect the skewness of the conveyor belt without external equipment, reducing production costs.

[0052] Optionally, the first chamber 121 of the roller holder 120 is a hollow chamber. By providing a hollow chamber in the roller holder 120, both ends of the roller body 110 can extend into the roller holder 120, the abutting portion 1222 of the floating member 122 can abut against the roller body 110 in the first chamber 121, and the sensing portion 1232 of the sensing member 123 can detect the amount of skewness of the roller body 110 in the first chamber 121 and adjust the detection accuracy of the sensing member 123 by moving away from or closer to the roller body 110.

[0053] Optionally, the roller seat 120 further includes a first cover plate 160 and a second cover plate 170. The first chamber 121 has a first opening 1211 on the side near the roller body 110, and the first cover plate 160 covers the first opening 1211. The second chamber 124 has a second opening 1241 on the side away from the roller body 110, and the second cover plate 170 covers the second opening 1241.

[0054] The first cover plate 160 covers the opening of the roller seat 120 facing the roller body 110, and the second cover plate 170 covers the side of the roller seat 120 away from the roller body 110. Simultaneously, the gear set is sealed within the cavity between the roller seat 120 and the second cover plate 170. The first cover plate 160 and the second cover plate 170 isolate the sensor 123, the floating element 122, and the gear set located on the outward side of the roller seat 120 from the external environment, thus protecting the floating element 122, the sensor 123, and the gear set, ensuring the normal operation of the roller 100. The knob 150 of the gear set is located on the outer surface of the second cover plate 170. Operators can adjust the detection accuracy of the sensor 123 by turning the knob 150 to drive the gear set located between the second cover plate 170 and the roller seat 120.

[0055] Optionally, roller seats 120 are provided at both ends of the roller body 110. The roller seats 120 located at both ends of the roller body 110 float and support the roller body 110 and detect the skewness of the roller body 110. The roller body 110 rotates between the two roller seats 120 to drive the material belt passing through the roller body 110.

[0056] like Figure 3 As shown, the roller body 110 includes a winding portion 111 for winding the material strip and a connecting portion 112 located at both ends of the winding portion 111 and capable of extending into the first cavity of the roller seat 120. The roller body 110 is rotatably connected to the roller seat 120 through the connecting portions 112 at both ends.

[0057] The present invention also proposes a belt drive device, which includes a guide roller 100 with belt skew detection function as described in any of the above embodiments. By installing the guide roller 100 with belt skew detection function in the belt drive device, the belt drive device can detect belt skew in a timely manner during winding or unwinding.

[0058] The conveyor belt drive device of this embodiment of the invention is equipped with the aforementioned conveyor roller 100 with conveyor belt skew detection function. The conveyor roller 100 extends the conveyor roller body 110 into the first chamber of the roller seat 120, and a floating member 122 and a sensing member 123 are arranged in the first chamber of the roller seat 120. The floating member 122 floats and supports the conveyor roller body 110, so that when the conveyor belt passing through the conveyor roller 100 skews, the conveyor roller body 110 can also shift relative to the roller seat 120. The sensing member 123 is used to detect the amount of shift of the conveyor roller body 110 relative to the roller seat 120. When the conveyor roller body 110 shifts, the sensing member 123 can detect the degree of skew of the conveyor roller body 110 and send the detection data outward to promptly remind the operator to correct the shift of the conveyor belt and the conveyor roller 100.

[0059] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0060] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.
