Description

Technical Field

[0001] The present invention relates to the technical field of hygiene product processing equipment, and particularly relates to a corner conveying device for coil slitting in the hygiene product industry. Background Art

[0002] Currently, in the hygiene product industry, the final products need to go through multiple processes. When transferring between processes, the materials are generally wound into a disk shape by circumferential rotation for the convenience of the next process. For example, in the existing coil slitting process, the coiled materials need to be slit into several strip-shaped materials and wound up before the next process. The slitting situations involved in the slitting process can be divided into one-to-two and one-to-many. In the one-to-many coil slitting process, the coil is slit into multiple strip-shaped materials, and the multiple strip-shaped materials need to be wound synchronously during winding. In some existing winding devices, winding devices arranged in a straight line are usually used to wind the multiple strip-shaped materials synchronously, and each strip-shaped material corresponds to a winding roller in a single winding device. In the application document with the publication (announcement) number CN110065834A, a core winding type winding unit for the hygiene product industry is disclosed. The winding unit in this application document is arranged in a straight line, and the unwinding and slitting device is arranged at the end of the winding unit and performs straight unwinding and slitting directly towards the direction of the winding unit. The strip-shaped materials are conveyed one by one from above the winding unit to the corresponding winding unit. However, in the specific use process, there are still the following problems: 1. The problem of equipment floor area; when the width of the material coil to be slit is greater than the width of the winding device, the entire slitting and winding equipment will be arranged in a T shape. As the width of the material coil increases, the overall width of the equipment will be larger, and the utilization rate of the site area is relatively low; 2. The problem of material unwinding; after the wide material coil is slit, the strip-shaped materials near both ends need to be corrected towards the middle of the material coil by the deviation rectifying rollers before being conveyed directly above the winding unit. However, the widths of the strip-shaped materials cut from coils of different widths are different, and the number of cut strip-shaped materials is also different. After changing the material, it is necessary to readjust the deviation angles of each deviation rectifying roller to perform re-calibration and centering, which is rather troublesome.

The corner mechanisms are arranged on the correction structures in a staggered manner layer by layer along the Y-axis direction.

[0006] As an improvement of the above solution, the correction structure includes a guide rod and a screw rod structure horizontally connecting the first fixed bracket and the second fixed bracket along the Y-axis direction, and a first movable base and a second movable base penetrated through the guide rod and the screw rod structure; The corner roller and the first conveying roller are respectively arranged on the first movable base and the second movable base.

[0007] As an improvement of the above-mentioned scheme, the screw structure includes an adjusting screw and an adjusting handle, one end of the adjusting screw passes through the first fixed bracket and is connected to the adjusting handle, and the other end is hinged to the second fixed bracket. The adjusting screw passes horizontally through the second movable base along the Y-axis direction, and a rotary encoder is provided on the outer facade of the first fixed bracket corresponding to the penetration position of the adjusting screw.

[0008] As an improvement of the above solution, the guide rod is symmetrically arranged on both sides of the screw rod, and the ends are respectively fixed to the first fixed bracket and the second fixed bracket, and the guide rod horizontally passes through the first movable base and the second movable base along the Y-axis direction.

[0009] As an improvement to the above solution, the corner mechanism includes a corner roller, a first conveying roller, and a third movable base disposed on the end face of the first movable base. The third movable base is aligned with the first conveying roller in the Y-axis direction, and the bottom of the third movable base is hinged to the first movable base.

[0010] As an improvement to the above solution, the second movable base is provided with vertical connecting portions at positions corresponding to both ends of the first conveying roller. Both ends of the first conveying roller are hinged to the vertical connecting portions, and a gap is reserved between the bottom of the first conveying roller and the second movable base. Both ends of the third movable base are clamped upward in a pincer shape at both ends of the corner roller, and a gap is reserved between the bottom of the corner roller and the third movable base.

In addition, when switching coiled materials with different widths, there is no need to adjust the corner angle of the corner roller to achieve centering due to the different widths of the strip-shaped materials, simplifying the process.

Specific embodiments

[0021] The following combines the drawings with relevant embodiments to illustrate the implementation manners of the present invention. The implementation manners of the present invention are not limited to the following embodiments, and the relevant necessary components involved in the present invention should be regarded as well-known technologies in the technical field, which can be known and mastered by those skilled in the technical field.

[0022] As Figure 1 shown, a corner conveying device for slitting coiled materials in the sanitary product industry includes an equipment main body 1. The equipment main body 1 includes a first corner conveying structure 2 and a second corner conveying structure 3 arranged in sequence along the X-axis direction. The first corner conveying structure 2 and the second corner conveying structure 3 are the same, and the first corner conveying structure 2 and the second corner conveying structure 3 are arranged in a staggered manner along the X-axis and Y-axis directions; As Figure 1 shown, in the technical solution of the corner conveying device of the present invention, the unwinding direction of the strip material is the X-axis, and the winding direction is the Y-axis. This corner conveying device is applied between the slitting device and the winding device in the production line. Among them, the winding device is arranged in a straight line along the Y-axis for winding, and the unwinding device unwinds the material along the X-axis into the slitting device. When in use, the material forms several strip materials conveyed in parallel after passing through the unwinding device and the slitting device. During the conveying process, the strip materials are lifted and turned through the corner conveying device, and the conveying state is converted from being conveyed in parallel along the X-axis straight line to being arranged layer by layer along the Z-axis and conveyed in a straight line along the Y-axis. Among them, the strip material at the top layer of the Z-axis is conveyed to the winding roller near the end of the winding device, and the strip material at the bottom layer of the Z-axis is conveyed to the winding roller near the front end of the winding device; It should be noted that during the unwinding process of the material on the unwinding device, when the width of the material exceeds the width of the first corner conveying structure 2, the strip-shaped material exceeding the width of the first corner conveying structure 2 crosses the first corner conveying structure 2 and is conveyed towards the second corner conveying structure 3, and the second corner conveying structure 3 is used to lift and turn the strip-shaped material of the ultra-wide part.

[0023] As Figures 1 to 4 shown, it should be noted that the first corner conveying structure 2 and the second corner conveying structure 3 are the same, the first corner conveying structure 2 and the second corner conveying structure 3 are arranged in a staggered manner along the X-axis and Y-axis directions, the strip-shaped materials are arranged side by side in the Y-axis direction, and the staggered arrangement of the first corner conveying structure 2 and the second corner conveying structure 3 can effectively solve the problem of the winding and turning of a large number of strip-shaped materials formed after the slitting of the wide-width coil material; The structures of the first corner conveying structure 2 and the second corner conveying structure 3 in the present invention are the same, so the technical solution description of the first corner conveying structure 2 is applicable to the second corner conveying structure 3. In one specific embodiment, the winding device can adopt a double-sided winding device arranged in a straight line. The first corner conveying structure 2 and the second corner conveying structure 3 are respectively arranged in a staggered manner corresponding to the winding rollers on both sides of the double-sided winding device, and the strip-shaped material of the ultra-wide part is wound on the other side of the double-sided winding device after being lifted and turned by the second corner conveying structure 3.

[0024] As Figures 2 to 6 shown, in the technical solution of the first corner conveying structure 2 of the present invention, the first corner conveying structure 2 includes a lifting mechanism 4, a corner mechanism 5 and a correction mechanism 6. The function of the lifting mechanism 4 is to lift the strip-shaped material to different Z-axis coordinates. The correction mechanism 6 is used to adjust the corner mechanism 5 to align with the strip-shaped material. The corner mechanism 5 is movably arranged along the length direction of the correction mechanism 6. The correction mechanism 6 extends along the Y-axis direction and has at least one movable base and a lead screw structure 64 for adjusting the movement of the movable base along the Y-axis direction; As Figure 2 and Figure 3As shown, in the technical solution of the lifting mechanism 4 of the present invention, the lifting mechanism 4 includes a plurality of lifting rollers 41 arranged layer by layer along the Z-axis direction. Adjacent two lifting rollers 41 are arranged at equal intervals. A pressure roller 42 is provided at the upper working position of the lifting roller 41. The strip-shaped material formed after the coil material is slit passes under the pressure roller 42. The pressure roller 42 keeps the strip-shaped material on the same horizontal plane, avoiding the phenomenon of fluctuating up and down during the conveying process due to different local tensions. After the strip-shaped material passes through the action of the pressure roller 42, it is neatly conveyed into the lifting roller 41. Each single lifting roller 41 corresponds to a single strip-shaped material, and the strip-shaped material is lifted to different horizontal heights; As Figure 5 and Figure 6 shown, in the technical solution of the corner mechanism 5 of the present invention, the corner mechanism 5 has a corner roller 51 and a first conveying roller 52. The corner roller 51 is aligned with the angular bisector between the X-axis and the Y-axis. The included angle between the first conveying roller 52 and the Y-axis is a right angle. The corner roller 51 is offset towards the starting end direction of the strip-shaped material conveying. During conveying, the strip-shaped material passes around under the corner roller 51 and is output above the corner roller 51, thereby realizing the turning of the strip-shaped material. The turned strip-shaped material is conveyed towards the first conveying roller 52 direction, that is, it turns to convey along the Y-axis direction.

[0025] As Figure 5 and Figure 6 shown, in the technical solution of the correction mechanism 6 of the present invention, the correction mechanism 6 includes a first fixed bracket 61 and a second fixed bracket 62 vertically arranged along the Z-axis direction and a plurality of layers of correction structures 63 arranged between the first fixed bracket 61 and the second fixed bracket 62; The correction structures 63 are arranged layer by layer along the Z-axis direction. Adjacent two groups of correction structures 63 are arranged at equal intervals. The corner mechanism 5 is arranged to move layer by layer and stagger in the Y-axis direction on the correction structures 63.

[0026] It should be noted that the correction mechanism 6 is used to adjust the coordinates of the corner mechanism 5 in the Y-axis direction, so that the corner mechanism 5 is on the X-axis transmission path of the strip-shaped material, thereby realizing the turning of the strip-shaped material. The positions between the correction structures 63 layer by layer correspond to the Z-axis positions of the lifted strip-shaped material.

[0027] Furthermore, in the technical solution of the correction structure 63, the correction structure 63 includes a guide rod 67 and a lead screw structure 64 horizontally connecting the first fixed bracket 61 and the second fixed bracket 62 along the Y-axis direction, and a first movable base 65 and a second movable base 66 sleeved on the guide rod 67 and the lead screw structure 64. The corner roller 51 and the first conveying roller 52 are respectively arranged on the first movable base 65 and the second movable base 66.

[0028] Further, in the above solution, the guide rods 67 are symmetrically arranged on both sides of the lead screw, and the ends are respectively fixed to the first fixed bracket 61 and the second fixed bracket 62. The guide rods 67 horizontally pass through the first movable base 65 and the second movable base 66 along the Y-axis direction.

[0029] It should be noted that the structure of the guide rods 67 guides the first movable base 65 and the second movable base 66. By rotating the lead screw structure 64, the Y-axis coordinate of the second movable base 66 can be adjusted. The first conveying roller 52 is arranged on the second movable base 66. Adjusting the Y-axis coordinate of the second movable base 66 correspondingly adjusts the Y-axis coordinate of the first conveying roller 52. Adjusting the Y-axis coordinates of two adjacent first conveying rollers 52 correspondingly adjusts the interlayer spacing of two adjacent strip materials after turning.

[0030] In the technical solution of the lead screw structure 64 of the present invention, the lead screw structure 64 includes an adjusting lead screw 641 and an adjusting handle 642. One end of the adjusting lead screw 641 passes through the first fixed bracket 61 and is connected to the adjusting handle 642, and the other end is hinged to the second fixed bracket 62. The adjusting lead screw 641 horizontally passes through the second movable base 66 along the Y-axis direction. A rotary encoder 643 is provided on the outer vertical surface of the first fixed bracket 61 corresponding to the passing position of the adjusting lead screw 641.

[0031] It should be noted that rotating the adjusting handle 642 drives the adjusting lead screw 641 to rotate, thereby driving the second movable base 66 to rotate along the Y-axis direction. The rotary encoder 643 is arranged at the driving end of the adjusting lead screw 641. By detecting the rotation angle of the lead screw, the position distance of the second movable base 66 is indirectly calculated, so as to accurately adjust the position of the second movable base 66 in the layer-by-layer correction structure 63.

[0032] In the technical solution of the corner mechanism 5 of the present invention, the corner mechanism 5 includes a corner roller 51, a first conveying roller 52, and a third movable base 53 arranged on the end face of the first movable base 65. The third movable base 53 is aligned with the first conveying roller 52 along the Y-axis direction. The bottom of the third movable base 53 is hinged to the first movable base 65.

[0033] The first conveying roller 52 moves with the second movable base 66, the corner roller 51 moves with the first movable base 65. The first movable base 65 is fixed on the guide rods 67. The Y-axis coordinate of the first movable base 65 is aligned with the Y-axis coordinate of the strip material conveying. The corner roller 51 is fixed on the third movable base 53. The third movable base 53 is hinged to the first movable base 65. A locking member is provided between the third movable base 53 and the first movable base 65. The locking member is one of a screwing screw or a screwing handle, and is inserted through the first movable base 65 and the third movable base 53, and has a locking effect on the first movable base 65 and the third movable base 53 after adjusting the rotation angle of the third movable base 53; It should be noted that the obliquely arranged corner roller 51 is used to turn the strip material. The inclination angle of the corner roller 51 determines the turning direction of the strip material. In the preferred embodiment of the present invention, the winding direction of the strip material is the Y-axis direction, and the unwinding direction of the strip material is the X-axis direction. Considering the floor area of the equipment, the included angle between the winding direction and the unwinding direction of the strip material is 90°. Therefore, the inclination angle of the corner roller 51 is 45°. After the strip material is turned by the corner roller 51, it is conveyed along the Y-axis away from the winding device, and then bypasses the first conveying roller 52 and the second conveying roller 71 in sequence and is conveyed towards the winding device above the corner mechanism 5; Regarding the problem of dealing with the floor area of the equipment, in the existing slitting and winding equipment, the unwinding and slitting device is usually arranged at one end of the winding equipment, that is, the unwinding direction of the material is the same as the winding direction of the material. In the winding equipment, the winding devices arranged in a straight line are usually used to wind multiple strip materials synchronously. Each single strip material corresponds to a winding roller in a single winding device. When facing a wide coil material, the width of the unwinding and slitting device is often greater than the width of the winding device, resulting in a T-shaped overall equipment. When retrofitting the unwinding and slitting device of the equipment in the later stage, the T-shaped equipment structure greatly limits its transformation in the width direction.

[0034] In the technical solution of the present invention, the unwinding and slitting device is arranged on the side of the end of the winding device, and the overall equipment is L-shaped. The unwinding direction of the unwinding and slitting device is perpendicular to the winding direction of the winding device. The corner conveying structure is arranged at the end of the winding device, and the material is turned and lifted through the corner conveying structure. When encountering a wide coil material, by modifying and increasing the width of the unwinding device, compared with the traditional T-shaped equipment, the L-shaped equipment will not affect the overall width of the equipment during the transformation in the width direction of the unwinding device, and a good aisle spacing can be maintained between adjacent equipment bodies 1; In the technical solution of the first conveying roller 52 of the present invention, vertical connecting portions 661 are provided at positions corresponding to both ends of the first conveying roller 52 on the second movable base 66. Both ends of the first conveying roller 52 are hinged to the vertical connecting portions 661, and a gap is reserved between the bottom of the first conveying roller 52 and the second movable base 66. Both ends of the third movable base 53 are clamped upward in a pincer shape at both ends of the corner roller 51, and a gap is reserved between the bottom of the corner roller 51 and the third movable base 53.

[0035] As Figure 7 shown, it should be noted that after the strip material turns out upward from the gap between the corner roller 51 and the third movable base 53, it turns out upward from the gap between the first conveying roller 52 and the second movable base 66. The strip material is horizontally output after turning through the corner roller 51, and is lifted and reversed by the first conveying roller 52 and the second conveying roller 71. The overall force on the strip material is relatively balanced. In the traditional way of directly reversing and outputting the material by setting a single corner roller 51 in an inclined plus corner way, the strip material will be subjected to an inclined torsion force, and the transmission stability will be affected.

[0036] Further, in the above solution, a conveying support 7 is provided above the corner mechanism 5. A plurality of second conveying rollers 71 aligned with the first conveying roller 52 in the Z-axis direction are provided on the conveying support 7, and the second conveying rollers 71 are arranged in a staggered manner layer by layer in the Y-axis direction.

[0037] It should be noted that the strip material conveyed through the corner roller 51 overlaps in the same Y-axis coordinate in the Z-axis direction. The first conveying roller 52 and the second conveying roller 71 arranged layer by layer convey the strip material to the winding device one by one layer by layer. The second conveying roller 71 is arranged above the corner conveying mechanism and the winding device. The strip material is conveyed to the winding roller of the winding device through the upper part of the equipment, making full use of the upper space of the equipment and reducing the floor area.

[0038] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
