Spindle type roll material winding device and winding process

Abstract

The application discloses a spindle type roll material winding device and a winding process. The device comprises a rack and a sub-roll winding unit. The sub-roll winding unit comprises a transfer roller group, a winding mechanism and a temporary storage mechanism. The application can realize the increase of the winding length by multiple times under the same roll diameter. The multiple times are equal to the number of single pass winding. The number of roll changing and joint in the later process is greatly reduced, which meets the needs of high-speed production, improves the efficiency and reduces the material waste rate. Meanwhile, the outer diameter of the sub-roll can be reduced by multiple times under the same winding length, which facilitates roll changing or transportation. The winding is not affected by the unwinding tension. On the other hand, based on the short temporary storage, movement switching is formed between the adsorption by the negative pressure adsorption head and pressure relief, so that the change of the sheet material can meet the demand of the single pass winding sheet material offset amount. Then, the reciprocating spindle line type winding is implemented without changing the transfer position of the sheet material.

Description

[0001] This application is a divisional application with the application date of November 21, 2024, application number 2024116684264, and name as Spindle-type coil unwinding, slitting and winding machine. Technical Field

[0002] The invention belongs to the field of textile processing equipment, and in particular relates to a spindle-type coiling device and a spindle-type coiling process. Background Art

[0003] Currently, for the slitting of roll materials (such as non-woven fabrics), it is necessary to first unroll, slit, and then rewind the rolls (sub-rolls) from a whole roll (parent roll). In other words, the parent roll is cut into pieces according to the required size and then rewound into multiple sub-rolls.

[0004] However, in the process from slitting to winding, the slitting sections of the non-woven fabric are basically separated relatively, and then the corresponding winding discs are used for side-by-side and synchronous winding. Therefore, there are the following technical defects:

[0005] 1) Once the number of sub-rolls after slitting is large, the space required for rewinding is basically arranged along the width of the mother roll (because the sub-rolls need to be arranged side by side with intervals), resulting in a high space requirement, difficult layout, and poor practicality;

[0006] 2) Because each sub-roll is wound in a constant rotational manner, the length of each sub-roll segment is limited as the roll diameter increases. Therefore, when the downstream equipment uses the reel to continue production, the number of roll changes and splices increases significantly. This not only fails to meet the actual high-speed production requirements, but also has low production efficiency and excessive splicing, resulting in material waste. In addition, the large roll diameter of the sub-rolls not only makes it inconvenient to change rolls up and down, but also makes transportation difficult due to their large size.

[0007] 3) Due to the large width of the parent roll, the tension formed during unwinding is different and has a certain fluctuation range. Therefore, it will cause the winding deviation in the subsequent winding process and the uneven winding tension resulting in inconsistent tightness. Such phenomena will frequently occur, thereby affecting the winding quality of the sub-roll. Summary of the Invention

[0008] The object of the present invention is to overcome the deficiencies of the prior art and provide an improved spindle-type coil winding device.

[0009] At the same time, the invention also relates to a spindle-type coiling process.

[0010] In order to achieve the above object, the technical solution adopted by the present invention is:

[0011] A spindle type roll material winding device, comprising a frame, a sub-roll winding unit, the sub-roll winding unit comprising a transfer roller group adjusted along a sheet width direction, a winding mechanism reciprocating in a spindle line type winding mode with the transfer roller group as a center and along the sheet width direction, a temporary storage mechanism between the transfer roller group and the winding mechanism, wherein the temporary storage mechanism has a cycle of driving the passing sheet to move between the detachment and the adhesion temporary storage rollers, the winding mechanism has a cycle of one reciprocating stroke, and the temporary storage mechanism completes a cycle of movement when the winding mechanism moves half a cycle; the temporary storage mechanism comprises a temporary storage frame, temporary storage rollers, and a negative pressure suction head, wherein the temporary storage frame is mounted on the roller seat, the temporary storage rollers are multiple, at least three of which are arranged side by side to form a temporary storage area, the negative pressure suction head is aligned with the temporary storage rollers in the middle of the temporary storage area, and the sheet keeps in contact with other temporary storage rollers when the sheet detaches from or adheres to the temporary storage rollers; the winding mechanism comprises a moving seat reciprocating along the sheet width direction and arranged on the frame, a winding component with a winding shaft mounted on the moving seat, and a tension adjusting component, wherein the tension adjusting component adaptively adjusts with the increase of the winding outer diameter.

[0012] According to a specific implementation and preferred aspect of the present application, the negative pressure suction surface formed by the negative pressure suction head is a plane, and is divided into at least three negative pressure cavities from left to right, each of which forms negative pressure suction at the same time, and there is a sequence in the pressure relief process. In some specific implementations, the mode of first middle and then two sides forms pressure relief. That is, the mode of first middle and then two sides (or the pressure relief mode of first two sides and then middle) forms pressure relief (that is, the three negative pressure cavities are not communicated), which makes the movement cycle more consistent, and the gradual movement further reduces the probability of sheet displacement, avoiding phenomena such as deviation, pulling, stacking, etc.

[0013] According to another specific implementation and preferred aspect of the present application, the transfer roller group comprises a roller seat, multiple transfer rollers arranged in parallel on the roller seat, and an online deviation corrector on the transfer transmission path formed thereby. The roller seat is adjusted based on the alignment requirement of the transfer roller group and the corresponding return transmission sub-loaded sheet, and the online deviation corrector is used to keep the sheet output stable.

[0014] Preferably, the roller seat is adjusted on the frame along the length direction of the transfer roller.

[0015] In some specific embodiments, the plurality of transfer rollers form a first transmission section, a second transmission section, and a third transmission section. The first transmission section is the receiving section, the online web guide is installed in the second transmission section, and the second transmission section is the web guide section. The third transmission section is the output section. This three-stage transmission not only avoids the impact of web guide adjustments on the sheet's entry and exit positions, but also provides favorable conditions for sheet buffering. Specifically, at least one of the transfer rollers forming the first transmission section can move up and down relative to the other transfer rollers to form a buffer.

[0016] Preferably, at least one of the transfer rollers forming the first transmission section can move up and down relative to the other transfer rollers to form a buffer.

[0017] Furthermore, a motion guide rod extending along the width of the machine frame is mounted on the frame, and the roller seat is slidably mounted on the motion guide rod via a sliding component, wherein the sliding component is a slide and / or sliding roller. Adaptive alignment adjustment is performed based on different slitting widths, increasing the practicality of sub-roll winding. At the same time, the slide is used for penetration, and the sliding roller is supported by the motion guide rod. When the sliding roller is driven to rotate or the slide is shifted, the roller seat can be shifted and adjusted in the width direction.

[0018] In addition, the tension adjustment component includes a flip arm installed on the movable seat and rotating around the width direction of the sheet, a tension transmission roller formed on the flip arm, and a power device that drives the flip arm to move and flip, wherein under the drive of the power device, as the winding outer diameter changes, the flip arm flips to gradually lift the tension transmission roller to provide adaptive tension.

[0019] Another technical solution of the present invention is: a spindle-type coil winding process, which adopts the above-mentioned spindle-type coil winding device and includes the following steps: after slitting, the non-woven fabric passes through a transmission roller group to transfer one of the multiple non-woven fabrics downward and forward, and performs online correction during the transfer process. After the correction, the sheet material moves forward and downward again through the temporary storage area, and then the negative pressure formed by the temporary storage area is adsorbed and released so that the non-woven fabric passing through is dynamically switched between tension and relaxation. The non-woven fabric is wound downward to the sub-roll winding shaft, and at the same time, the sub-roll winding shaft rotates and reciprocates along the left and right directions to wind the non-woven fabric in a spindle-like manner, so as to complete the winding of each sub-roll, wherein the temporary storage area drives the passing sheet material to move between detachment and bonding with the temporary storage roller as one cycle, and the winding mechanism has one reciprocating stroke as one movement cycle, and when the winding mechanism moves half a cycle, the temporary storage mechanism completes one movement cycle. Due to the application of the above-mentioned technical solution, the present invention has the following advantages compared with the prior art:

[0020] In the process of forming sub-rolls from the existing parent roll cutting, once the number of sub-rolls after cutting is large, the space required for winding is basically arranged along the width direction of the parent roll (because each sub-roll needs to be arranged side by side), resulting in high space requirement, difficult layout, and poor practicability. At the same time, each sub-roll is wound in a constant self-rotation manner, and as the roll diameter increases, the winding length of each segment of the sub-roll is limited. Therefore, when using the downstream equipment of the roll stock, the number of roll changing and jointing is greatly increased, which not only cannot meet the actual high-speed production needs, but also has low production efficiency and causes material waste due to excessive joints. In addition, due to the large diameter of the sub-roll, the up-down roll changing operation is inconvenient, and transportation is difficult due to the large volume. At the same time, due to the large width of the parent roll, the tension formed during unwinding is different and has a certain fluctuation range, which causes the winding to deviate during the subsequent winding process and the tightness to be inconsistent due to uneven winding tension, thereby affecting the winding quality of the sub-roll and other problems. The present application ingeniously solves the various shortcomings of the existing structure through overall design of the spindle type roll stock winding device. After cutting, the non-woven fabric is transferred downward and forward by one transmission roller group from multiple non-woven fabrics, and online correction is performed during the transfer process. The sheet material after correction is transferred forward and downward again through the temporary storage area, and then the negative pressure adsorption and release formed by the temporary storage area are used to dynamically switch the non-woven fabric between tension and relaxation. The non-woven fabric is wound downward to the sub-roll winding shaft, and at the same time, the non-woven fabric is wound in a spindle line type by the self-rotation winding of the sub-roll winding shaft and the reciprocating motion along the left and right directions, thereby completing the winding of each sub-roll. The temporary storage area takes the movement of the passing sheet material between the separation and adhesion of the temporary storage roller as a period, and the winding mechanism takes one reciprocating stroke as a movement period. Therefore, the present application coordinates the temporary storage movement period and the reciprocating displacement period on the premise of not affecting the distribution of each sheet material, realizes spindle line type sub-roll collection, increases the winding length by multiple times under the same roll diameter, and the multiple times are equal to the number of single pass winding, thereby greatly reducing the number of roll changing and jointing in the subsequent processing, meeting the needs of high-speed production, improving efficiency, and reducing material waste rate. In addition, the outer diameter of the sub-roll can be reduced by multiple times under the same winding length to facilitate roll changing or transportation, and the winding is not affected by the unwinding tension. On the other hand, based on the short temporary storage, the movement switching between the adsorption and pressure relief of the negative pressure adsorption head is formed to make the change of the sheet material sufficient to meet the demand of single pass winding sheet material deviation, thereby implementing the reciprocating spindle line type winding without changing the transfer position of the sheet material.

[0037] like Figures 1 to 8 As shown, the spindle-type coil unwinding, slitting and winding machine of this embodiment includes an unwinding device ①, a slitting device ② and a winding device ③.

[0038] Specifically, the unwinding device ① is a commonly used mother roll unwinding device, and the mother roll can be automatically replaced and replenished.

[0039] The slitting device ② adopts roller cutting, that is, the unwound coil is cut by rollers to form multiple sliced ​​sheets, and the sliced ​​sheets are transported backward side by side.

[0040] The winding device ③ is used to load the side-by-side sheets one by one (transfer them separately), and includes a frame 1 and a sub-roll winding unit 2, wherein the frame 1 extends along the front-to-back direction (corresponding to the length direction), and a plurality of transmission roller groups 3 are distributed side by side and spaced apart in the length direction of the frame. After slitting, the sheets are transmitted backward in side by side and each time they pass through a transmission roller group 3, a sheet is loaded, and each loaded sheet is returned downward and forward, and the sub-roll winding unit 2 is used to rewind the returned sheet, wherein there are multiple sub-roll winding units 2, and they are arranged at intervals along the extension direction of the frame 1, and each sub-roll winding unit 2 corresponds to a transmission roller group 3.

[0041] Specifically, a splicing roller 4 is mounted on the frame 1, parallel to the conveyor roller assembly 3. The slit sheets pass side by side over the splicing roller 4, where they are sequentially loaded by the conveyor roller assembly 3. The slit coils are then transferred to the rewinding device, where each sheet is subsequently loaded (and transferred individually). In this example, the slit sheets passing through the splicing roller 4 are transported backward with equal spacing and relative spacing, thus preventing motion interference.

[0042] In this example, the slit sheets are arranged along the length of the feeder roller 4 in the order 1, 2, 3, ...N, with the sheets grouped by odd and even numbers, and the loading of each group of sheets is completed sequentially and successively. By sequentially loading the odd and even groups, the movement interference between adjacent groups of sheets caused by a long transport route is avoided.

[0043] In some specific embodiments, each sub-roll winding unit 2 includes a transfer roller group 20 that is adjusted along the width direction of the sheet to achieve alignment with the returned divided sheet, a winding mechanism 21 that is centered on the transfer roller group 20 and reciprocates in a spindle-like manner along the width direction of the sheet, and a temporary storage mechanism 22 located between the transfer roller group 20 and the winding mechanism 21, wherein each transfer roller group 20 is aligned with the corresponding returned divided sheet, the temporary storage mechanism 22 drives the passing sheet to move between detachment and adhesion to the temporary storage roller in one cycle, the winding mechanism 21 has one reciprocating stroke as one movement cycle, and when the winding mechanism 21 moves half a cycle, the temporary storage mechanism 22 completes one movement cycle.

[0044] In the example, every two adjacent roller groups 20 are arranged staggered in the width direction of the frame 1, so that the returned material can be aligned with the front material, reducing the probability of material deviation or stacking, improving the flatness of material transmission and transfer, and facilitating winding. The roller group 20 includes a roller seat 200, a plurality of transfer rollers 201 installed on the roller seat 200 and arranged in parallel with each other, and an online deviation corrector 202 located on the formed transfer transmission path, wherein the roller seat 200 is adjusted on the frame 1 along the length direction of the transfer roller. Based on the adjustment of the roller seat to meet the alignment requirements of the transfer roller group and the corresponding returned material, and based on the online deviation corrector to keep the material output stable.

[0045] In some embodiments, a plurality of transfer rollers 201 form a first transmission section, a second transmission section and a third transmission section, wherein the first transmission section is a lead-in section, the online deviation corrector 202 is installed on the second transmission section, and the second transmission section is a deviation correction section, and the third transmission section is an output section. Based on the three-section transmission, not only the change of the in-out position of the material caused by deviation correction is avoided, but also the caching of the material is facilitated. Specifically, at least one of the transfer rollers 201 forming the first transmission section can move up and down relative to the other transfer rollers 201 to form a cache. In the example, four transfer rollers 201 are used to form the first transmission section, two of which are fixed, and the other two are adjusted in position up and down by rotating arms to realize caching in emergency state. The online deviation corrector 202 uses an optical sensor to obtain material information and then adjusts the deviation of the material, which is a conventional product.

[0046] The winding mechanism 21 includes a moving seat 210 reciprocally arranged on the frame 1 along the width direction of the material, a winding component 211 with a winding shaft installed on the moving seat 210, and a tension adjusting component 212 which is adaptively adjusted with the increase of the winding outer diameter. Specifically, the tension adjusting component 212 includes a turnover arm a rotatably installed on the moving seat 210 around the width direction of the material, a tension transmission roller b formed on the turnover arm a, and a power device c driving the turnover arm a to turn over. With the change of the winding outer diameter, the turnover arm a turns over to gradually lift the tension transmission roller b to provide adaptive tension under the driving of the power device c.

[0047] The temporary storage mechanism 22 comprises a temporary storage rack 220, a plurality of temporary storage rollers 221, and a negative pressure suction head 222, wherein the temporary storage rack 220 is installed on the roller base 200, the plurality of temporary storage rollers 221 are arranged in parallel, at least three of which form a temporary storage area, and the negative pressure suction head 222 is aligned with the temporary storage rollers 221 in the middle of the temporary storage area, and the sheet material is in contact with other temporary storage rollers 221 when the sheet material is separated from or adhered to the temporary storage rollers 221. The temporary storage here refers to a short-term storage, in other words, a motion switching is formed between the suction and pressure relief of the negative pressure suction head 222, so that the change of the sheet material is sufficient to meet the requirement of the single-pass winding sheet material offset amount, thereby implementing the reciprocating spindle line winding without changing the transfer position of the sheet material.

[0048] Specifically, the negative pressure suction surface formed by the negative pressure suction head 222 is a plane, and is divided into at least three negative pressure cavities from left to right, at this time, the negative pressure cavities simultaneously form negative pressure suction, but there is a sequence in the pressure relief process, in this example, the mode of first middle and then both sides (or the pressure relief mode of first both sides and then middle) forms pressure relief (that is, the three negative pressure cavities are not connected), which makes the motion cycle more consistent, and the gradual motion further reduces the probability of sheet material displacement, avoiding phenomena such as offset, pulling, stacking, etc.

[0049] In addition, a motion guide rod 10 extending along the width direction of the motion guide rod 10 is installed on the rack 1, and the roller base 200 is slidably installed on the motion guide rod 10 through a sliding component H, wherein the sliding component H is a sliding seat h1 and a sliding roller h2. Adaptive alignment adjustment is made based on different slitting widths, the practicability of the sub-roll winding is increased, the sliding seat h1 is used for penetration, and the sliding roller h2 is used for rolling and supporting on the motion guide rod 10, and when the sliding roller h2 is driven to rotate or the sliding seat h1 is displaced, the displacement adjustment of the roller base 200 in the width direction can be implemented.

[0050] The implementation process of the embodiment is as follows:

[0051] S1, mother roll unwinding

[0052] The non-woven fabric mother roll is installed to the unwinding station, and the non-woven fabric is unwound backward;

[0053] S2, roll cutting

[0054] The unwound non-woven fabric passes through the slitting machine, and is cut into a plurality of non-woven fabrics by the corresponding slitting roller knives, and the plurality of non-woven fabrics are kept in parallel and transmitted backward;

[0055] S3, sub-roll winding

[0056] The multiple pieces of non-woven fabric after slitting are connected by the connecting roller, and are transmitted backward while being kept apart, and one piece of the multiple pieces of non-woven fabric is transferred downward and forward by each transmission roller group, and is rectified on line in the process of transfer, and the piece (non-woven fabric piece) after rectification is transmitted forward and downward again through the temporary storage area, and is then adsorbed and released by the negative pressure formed in the temporary storage area, so that the non-woven fabric is dynamically switched between tension and relaxation, and the non-woven fabric is wound downward to the sub-roll winding shaft, and is wound by the self-rotation of the sub-roll winding shaft and reciprocated along the left-right direction to be wound in the form of a spindle line, so that the winding of each sub-roll is completed.

[0057] Specifically, in S1, the mother roll has an automatic position compensation function, and after the winding of the current roll is completed, the winding of the next roll is continued through the joint. In S2, the slitting roller cutter used is a common disc cutter, and the non-woven fabric is cut at a constant width by the roller cutter, and the non-woven fabric is kept flat in the process of cutting by positive pressure blowing, and the slip generated in the cutting is also reduced. In S3, the temporary storage area takes one period as the movement of the piece passing through the temporary storage roller between separation and adhesion, and the winding mechanism takes one reciprocating stroke as one movement period, and the temporary storage mechanism completes one movement period when the winding mechanism moves half a period.

[0058] In summary, on the one hand, the present invention is based on the layout of the front-to-back direction of the long strip assembly line, which can not only complete the simultaneous winding of multiple sub-rolls, but also meet the needs of the workshop layout of most manufacturers. At the same time, the sub-rolls are wound in a return manner to shorten the overall length, and the movement influence of the sub-loaded sheet transmission on the slitting or sub-roll winding is avoided; on the other hand, based on the coordination of the temporary storage movement cycle and the reciprocating shift cycle, the spindle line sub-roll collection is realized without affecting the loading of each sheet, that is, the winding length is increased by multiple times under the same roll diameter, and the multiple is equal to the number of single-pass winding lanes, which greatly reduces the number of subsequent processing roll changes and joints, meets the needs of high-speed production, improves efficiency and reduces material waste rate; in addition, it can also achieve the same winding length. The outer diameter of the sub-roll is reduced by multiples to facilitate roll changing or transportation; the third aspect is to transfer the slit roll material to the winding device based on the connecting roller, and then load each sheet in progress (separately), and at the same time, based on the loading of odd and even groups in sequence, it is avoided that there is a gap between two adjacent groups of sheets due to the long transmission route. Motion interference; fourthly, the returned sheet can keep the forward sheet relatively aligned, reducing the probability of sheet deviation or stacking, so as to improve the flatness of sheet transmission and reprinting, and thus facilitate winding; fifthly, based on the roller seat adjustment to meet the transfer roller group and the corresponding return load sheet alignment requirements, and based on the online corrector to maintain smooth sheet output; sixthly, based on three-stage transmission, it not only avoids the correction adjustment from affecting the change of the sheet's entry and exit position, but also provides favorable conditions for the sheet's caching; seventhly, the negative pressure adsorption head forms a motion switch between adsorption and pressure relief, so that the change of the sheet is sufficient to meet the requirement of the single-pass winding sheet offset, and then implements reciprocating spindle-type winding without changing the sheet's transfer transmission position; eighthly, based on different slitting widths, adaptive alignment adjustment is performed to increase the practicality of sub-roll winding, and at the same time, a slide is used for penetration, and a sliding roller rolling frame is supported on the motion guide rod. When the sliding roller is driven to rotate or the slide is shifted, the roller seat can be shifted in the width direction.

Their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly.
