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 processing technology for automatic unwinding, slitting and winding of a spindle-type coiled material. Background Art

[0003] At present, for the slitting of roll materials (such as non-woven fabrics), it is necessary to first unroll, slit, and then rewind (sub-rolls) from a whole roll of roll material (parent roll). In other words, the parent roll is slit according to the required size and then rolled up to form multiple sub-rolls.

[0004] However, in the process from slitting to winding, the slitting sections of the nonwoven fabric are basically relatively separated, 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 there are a large number of sub-rolls after slitting, the space required for rewinding is basically arranged along the width direction of the mother roll (because each sub-roll needs to be arranged side by side at intervals), resulting in a high space requirement, difficult layout, and poor practicality;

[0006] 2) Since each sub-roll is wound in a constant rotational manner, as the roll diameter increases, the length of each sub-roll is limited. Therefore, when the downstream equipment uses the reel material to continue production, the number of roll changes and joints increases significantly. In other words, it not only cannot meet the actual high-speed production needs, but also has low production efficiency and excessive joints that will cause material waste. In addition, due to the large roll diameter formed by the sub-roll, it is not only inconvenient to change the rolls up and down, but also difficult to transport due to its large size;

[0007] 3) Due to the large width of the mother roll, the tension formed during unwinding is different and has a certain range of variation. Therefore, it will cause frequent winding deviations and inconsistent tightness due to uneven winding tension during the subsequent winding process, which will affect 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 to provide an improved process for automatically unwinding, slitting and winding a spindle-type coil.

[0009] In order to achieve the above object, the technical solution adopted by the present invention is:

[0010] A spindle-type coiled material automatic unwinding, slitting and winding processing technology, comprising:

[0011] S1, mother roll unwinding

[0012] The non-woven fabric mother roll is installed to the unwinding station, and the non-woven fabric is unwound backwards;

[0013] S2, Roller Cutting

[0014] The unrolled nonwoven fabric passes through the slitting machine and is cut by the corresponding slitting rollers into multiple strips of nonwoven fabric that are kept side by side and transported backwards;

[0015] S3, sub-roll rewinding

[0016] The multiple strips of non-woven fabrics after slitting are connected by the connecting rollers and are wound up by the multiple sub-roll winding units, and the slit non-woven fabric strips are transmitted backward while being kept relatively separated, and each time one of the multiple non-woven fabrics passes through a transmission roller group, one of the multiple non-woven fabrics is transferred downward and forward, and online correction is performed during the transfer process. After the correction, the non-woven fabric strips pass forward and downward through the temporary storage area again, 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, and the non-woven fabric is wound downward onto the sub-roll winding shaft, and at the same time, the non-woven fabric is wound up in a spindle-like manner by the self-rotation and reciprocating motion of the sub-roll winding shaft along the left and right directions, so as to complete the winding of each sub-roll, wherein the temporary storage area drives the non-woven fabric passing through to move between separation and bonding with the temporary storage roller as one cycle, and the winding mechanism has one reciprocating stroke as one movement cycle, and the temporary storage mechanism completes one movement cycle when the winding mechanism moves half a cycle.

[0017] Preferably, in step S3, the sub-roll winding unit includes a transfer roller group that is adjusted along the width direction of the sheet to achieve alignment with the returned sub-loaded sheet, a winding mechanism that is centered on the transfer roller group and reciprocates in a spindle-like manner along the width direction of the sheet, and a temporary storage mechanism located between the transfer roller group and the winding mechanism, wherein the temporary storage mechanism includes a temporary storage rack, a temporary storage roller, and a negative pressure adsorption head, wherein the temporary storage rack is installed on the roller seat, and there are multiple temporary storage rollers, among which at least three temporary storage rollers are arranged side by side to form a temporary storage area.

[0018] In some specific embodiments, the negative pressure adsorption head is aligned with the temporary storage roller in the middle of the temporary storage area, and the sheet remains in contact with other temporary storage rollers when the sheet is detached from or attached to the temporary storage roller.

[0019] According to a specific implementation and preferred aspect of the present invention, the negative pressure adsorption surface formed by the negative pressure adsorption head is a plane, and is divided into at least three negative pressure chambers from left to right, each negative pressure chamber forms negative pressure adsorption at the same time, and there is a sequence in the pressure relief process. In step S3, the mode of first the middle and then the two sides is used for pressure relief. That is, the mode of first the middle and then the two sides (or the pressure relief mode of first the two sides and then the middle) forms pressure relief (that is, the three negative pressure chambers are not connected), which makes the movement cycle more consistent, and the progressive movement further reduces the probability of sheet displacement, avoiding offset, pulling, stacking and the like.

[0020] According to another specific implementation and preferred aspect of the present invention, in step S1, the mother roll has an automatic filling function, and after the previous roll is unrolled, the next roll continues to unroll through the joint.

[0021] According to another specific implementation and preferred aspect of the present invention, in step S2, the slitting roller used is a commonly used disc cutter, and the nonwoven fabric is cut into equal widths under the roller cutting of the disc cutter, wherein positive pressure blowing is used during the slitting. That is, the nonwoven fabric is kept flat by positive pressure blowing during the slitting process, and the slippage generated during the slitting is also reduced.

[0022] According to another specific implementation and preferred aspect of the present invention, the processing equipment used includes an unwinding device, a slitting device, and a winding device, wherein the unwinding device is used for unwinding the mother roll, the slitting device is used for slitting the roll and transmitting the slit sheets side by side backwards, the winding device is used for winding the sub-rolls, and the winding device includes a frame and a sub-roll winding unit, the frame extends front and back along the sheet transmission direction, and a plurality of transmission roller groups are distributed side by side and at intervals in the length direction of the frame, the sheets after slitting are transmitted side by side backwards and each sheet is loaded after passing through a transmission roller group, and each loaded sheet is transmitted downward and back forward; there are a plurality of sub-roll winding units, and they are arranged at intervals along the length direction of the frame, and each sub-roll winding unit corresponds to one transmission roller group.

[0023] Preferably, a connecting roller is installed on the frame, and the connecting roller is parallel to the transmission roller group. The slit sheets pass through the connecting roller side by side and are sequentially loaded by the transmission roller group.

[0024] In some specific embodiments, the slit sheets are arranged in the order of 1, 2, 3...N along the length direction of the connecting roller, wherein the sheets are grouped according to odd and even numbers, and the loading of each group of sheets is completed sequentially and successively. Based on the sequential loading of odd and even groups, the movement interference between two adjacent groups of sheets caused by the long transmission route is avoided.

[0025] The sliced ​​materials passing through the connecting rollers are kept at equal intervals and are relatively spaced and transported backwards.

[0026] Each adjacent two transfer roller groups are arranged in a staggered manner in the width direction of the frame.

[0027] In addition, the transfer roller group includes a roller seat, a plurality of transfer rollers mounted on the roller seat and arranged parallel to each other, and an online deflection corrector located on the formed transfer transmission path. The roller seat is adjusted to meet the alignment requirements of the transfer roller group and the corresponding return-transported divided sheets, and the online deflection corrector is used to maintain the smooth output of the sheets.

[0028] Preferably, the roller seat is slidably adjusted on the frame along the length direction of the transfer roller.

[0029] In some specific embodiments, a first transmission section, a second transmission section, and a third transmission section are formed between the plurality of transfer rollers, wherein the first transmission section is a receiving section, the online deflection corrector is installed on the second transmission section, and the second transmission section is a deflection correction section, and the third transmission section is an output section. Based on the three-stage transmission, not only the deflection correction adjustment is avoided to affect the change of the in-and-out position of the sheet, but also favorable conditions are provided for the caching of the sheet. 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 cache.

[0030] 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.

[0031] Furthermore, a motion guide rod extending along the width direction is installed on the frame, and the roller seat is slidably installed on the motion guide rod through a sliding component, wherein the sliding component is a sliding seat and / or a sliding roller. Adaptive alignment adjustment is performed based on different slitting widths to increase the practicality of sub-roll winding. At the same time, a sliding seat is used for penetration, and a sliding roller is used to roll the frame supported on the motion guide rod. When the sliding roller is driven to rotate or the sliding seat is displaced, the displacement adjustment of the roller seat in the width direction can be implemented.

[0032] In addition, the tension adjustment component includes a flip arm mounted on the movable seat and rotating around the sheet width direction, a tension transmission roller formed on the flip arm, and a power device driving the flip arm to move and flip, wherein under the drive of the power device, as the outer diameter of the winding changes, the flip arm flips to gradually lift the tension transmission roller to provide adaptive tension. Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0033] In the existing process of winding up sub-rolls formed by slitting the mother roll, once the number of sub-rolls after slitting is large, the space required for winding is basically arranged along the width direction of the mother roll (because the sub-rolls need to be arranged side by side with intervals), resulting in high requirements for the required site space, difficulty in layout, and poor practicality; at the same time, since each sub-roll is wound in a constant rotation manner, and as the roll diameter increases, the winding length formed by each section of the sub-roll is limited, therefore, when the downstream equipment of the reel continues to produce, the number of roll changes and joints is greatly increased, that is, not only can it not meet the actual high-speed production needs, but also the production efficiency is reduced. Low efficiency and too many joints will cause waste of materials. In addition, due to the large roll diameter formed by the sub-roll, it is not only inconvenient to change the rolls up and down, but also difficult to transport due to its large size. At the same time, due to the large width of the mother roll itself, the tension formed in the unwinding is different and there is a certain range of variation. Therefore, it will cause the winding deviation in the subsequent winding process and the phenomenon of inconsistent tightness due to uneven winding tension, which will affect the winding quality of the sub-roll and other shortcomings. The present invention cleverly solves various deficiencies of the existing structure by overall design of the processing technology of automatic unwinding, slitting and winding of the spindle-type coil.After adopting the processing technology of automatic unwinding, slitting and winding of the spindle-type coil, the non-woven fabric mother roll is installed on the unwinding station, and the non-woven fabric is unwound backward; the unwound non-woven fabric passes through the slitting machine, and is cut by the corresponding slitting roller to form multiple non-woven fabrics that are kept side by side and transmitted backward; the multiple non-woven fabrics that have been cut are connected by the connecting roller, and are wound up by multiple sub-roll winding units, and the cut non-woven fabric strips are transmitted backward while being relatively separated, and each time one of the multiple non-woven fabrics passes through a transmission roller group, one of the multiple non-woven fabrics is transferred downward and forward, and online transfer is carried out during the transfer process. After the correction, the non-woven fabric strip moves forward and downward through the temporary storage area again, 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 roll the non-woven fabric in a spindle-like manner to complete the winding of each sub-roll. The temporary storage area drives the non-woven fabric passing through to move between separation and bonding with the temporary storage roller as one cycle, and the winding mechanism has one reciprocating stroke as one movement cycle, and the winding mechanism moves half a cycle. During the cycle, the temporary storage mechanism completes a movement cycle. Therefore, on the one hand, the present invention is based on an assembly line layout, which can not only complete the simultaneous winding of multiple sub-rolls, but also meet the needs of most manufacturers' workshop layouts. At the same time, based on the return transfer, the overall length is shortened, and the movement influence of the divided sheet transmission on the slitting or sub-roll winding is avoided. In addition, 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 load sharing of each sheet, that is, the winding length is increased by multiple times under the same roll diameter, and the multiple is the same as the single-pass winding. The number of passes is equal, which greatly reduces the number of roll changes and joints in the subsequent processing, meets the needs of high-speed production, improves efficiency and reduces material waste rate; at the same time, it can also achieve equal winding length, and the outer diameter of the sub-roll is reduced by multiples to facilitate roll changing or transportation, and the winding is not affected by the unwinding tension; on the other hand, based on short-term retention, the negative pressure adsorption head performs motion switching between adsorption and pressure relief, so that the change of the sheet is sufficient to meet the demand for the offset of the single-pass winding sheet, and then implements reciprocating spindle line winding without changing the transfer position of the sheet.

[0050] 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.

[0051] Specifically, the unwinding device ① is a commonly used mother roll unwinding device, and the mother roll can be automatically replaced and replenished.

[0052] The slitting device ② adopts roller cutting, that is, the unreeled coil material is cut by rollers to form a plurality of slit sheets, and the slit sheets are simultaneously transmitted backward side by side.

[0053] 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 arranged side by side and spaced apart in the length direction of the frame, and the sheets after slitting are transmitted backward in side by side and each sheet is loaded after passing through a transmission roller group 3, 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 a plurality of 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.

[0054] Specifically, a connecting roller 4 is installed on the frame 1, and the connecting roller 4 is parallel to the transmission roller group 3. The slit sheets pass through the connecting rollers 4 side by side and are sequentially loaded by the transmission roller group 3. The slit coils are transferred to the winding device, and then each sheet is loaded (reloaded separately) in progress. In this example, the slit sheets passing through the connecting rollers 4 are kept at equal intervals and are relatively spaced and transferred backward to avoid motion interference.

[0055] In this example, the slit sheets are arranged in the order of 1, 2, 3...N along the length direction of the connecting roller 4, where they are grouped by odd and even numbers, and the loading of each group of sheets is completed in sequence. Based on the loading of odd and even groups in sequence, the movement interference between two adjacent groups of sheets caused by the long transmission route is avoided.

[0056] 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 bonding with the temporary storage roller as one cycle, the winding mechanism 21 has a 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.

[0057] In this example, each adjacent two transfer roller groups 20 in the front and rear are staggered in the width direction of the frame 1. This allows the returned sheets to be aligned with the forward sheets, reducing the probability of offset or stacking of the sheets, improving the flatness of sheet transmission and reprinting, and making it easier to reel them up. The transfer roller group 20 includes a roller seat 200, a plurality of transfer rollers 201 mounted on the roller seat 200 and arranged parallel to each other, and an online deviation corrector 202 located on the formed transfer transmission path, wherein the roller seat 200 is slidably adjusted on the frame 1 along the length direction of the transfer roller. The roller seat is adjusted to meet the alignment requirements of the transfer roller group and the corresponding returned divided sheets, and the online deviation corrector is used to maintain smooth output of the sheets.

[0058] In some specific embodiments, a first transmission section, a second transmission section and a third transmission section are formed between multiple transfer rollers 201, wherein the first transmission section is a receiving section, the online deflection corrector 202 is installed on the second transmission section, and the second transmission section is a deflection correction section, and the third transmission section is an output section. Based on the three-stage transmission, it not only avoids the change of the in-and-out position of the sheet material affected by the deflection correction adjustment, but also provides favorable conditions for the caching of the sheet material. 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 this example, four transfer rollers 201 are used to form the first transmission section, two of which are fixed, and the other two are transferred by a rotating arm to adjust the up and down position to achieve caching in an emergency state. The online deflection corrector 202 uses a photoelectric sensor to obtain sheet information, and then adjusts the offset of the sheet material, which is a conventional product.

[0059] The winding mechanism 21 includes a movable seat 210 arranged on the frame 1 for reciprocating along the width direction of the sheet, a winding component 211 installed on the movable seat 210 and having a winding shaft, and a tension adjustment component 212, wherein the tension adjustment component 212 is adaptively adjusted as the outer diameter of the winding increases. Specifically, the tension adjustment component 212 includes a flip arm a installed on the movable seat 210 for rotating around the width direction of the sheet, a tension transmission roller b formed on the flip arm a, and a power device c for driving the flip arm a to move and flip, wherein under the drive of the power device c, as the outer diameter of the winding changes, the flip arm a flips to gradually lift the tension transmission roller b to provide adaptive tension.

[0060] The temporary storage mechanism 22 includes a temporary storage frame 220, a temporary storage roller 221, and a negative pressure adsorption head 222, wherein the temporary storage frame 220 is installed on the roller seat 200, there are multiple temporary storage rollers 221, at least three of which are arranged side by side to form a temporary storage area, the negative pressure adsorption head 222 is aligned with the temporary storage roller 221 in the middle of the temporary storage area, and when the sheet is separated from or attached to the temporary storage roller 221, the sheet remains in contact with other temporary storage rollers 221. Temporary storage here refers to short-term retention, in other words, the negative pressure adsorption head 222 forms a motion switch between adsorption and pressure relief, so that the change of the sheet is sufficient to meet the offset requirement of the single-pass winding sheet, and then the reciprocating spindle line winding is implemented without changing the transfer position of the sheet.

[0061] Specifically, the negative pressure adsorption surface formed by the negative pressure adsorption head 222 is a plane, and is divided into at least three negative pressure chambers from left to right. At this time, each negative pressure chamber forms negative pressure adsorption at the same time, but there is a sequence in the pressure relief process. In this example, the mode of first the middle and then the two sides (or the pressure relief mode of first the two sides and then the middle) forms pressure relief (that is, the three negative pressure chambers are not connected), which makes the movement cycle more consistent, and the progressive movement further reduces the probability of sheet displacement, avoiding offset, pulling, stacking and other phenomena.

[0062] In addition, a motion guide rod 10 extending along the width direction is installed on the frame 1, and the roller seat 200 is slidably installed on the motion guide rod 10 through a sliding component H, wherein the sliding component H is a slide seat h1 and a sliding roller h2. Adaptive alignment adjustment is performed based on different slitting widths to increase the practicality of sub-roll winding. At the same time, the slide seat h1 is used for penetration, and the sliding roller h2 is used for rolling support on the motion guide rod 10. When the sliding roller h2 is driven to rotate or the slide seat h1 is displaced, the displacement adjustment of the roller seat 200 in the width direction can be implemented.

[0063] The implementation process of this embodiment is as follows:

[0064] S1, mother roll unwinding

[0065] The non-woven fabric mother roll is installed to the unwinding station, and the non-woven fabric is unwound backwards;

[0066] S2, Roller Cutting

[0067] The unrolled nonwoven fabric passes through the slitting machine and is cut by the corresponding slitting rollers into multiple strips of nonwoven fabric that are kept side by side and transported backwards;

[0068] S3, sub-roll rewinding

[0069] After the slitting, the multiple strips of non-woven fabrics are connected by the connecting rollers and are transmitted backwards relatively separated (up and down cross transmission is also possible here), and each time one of the multiple strips of non-woven fabrics passes through a transmission roller group, one of the multiple strips of non-woven fabrics is transferred downward and forward, and online correction is performed during the transfer process. After the correction, the sheet (non-woven fabric strip) passes forward and downward through the temporary storage area again, 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, and the non-woven fabric is wound downward onto 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, thereby completing the winding of each sub-roll.

[0070] Specifically, in S1, the mother roll has an automatic filling function. After the previous roll is unwound, the next roll continues to unwind through the joint. In S2, the slitting roller used is a commonly used disc cutter, and the non-woven fabric is cut into equal widths under the roller cutting of the disc cutter. At the same time, the non-woven fabric is kept flat by positive pressure blowing during the slitting process, and the slip generated during the slitting is also reduced. In S3, the temporary storage area drives the passing sheet to move between the separation and bonding of the temporary storage roller as a cycle, and the winding mechanism has a reciprocating stroke as a movement cycle, and when the winding mechanism moves half a cycle, the temporary storage mechanism completes a movement cycle.

[0071] In summary, on the one hand, the present invention is based on the layout of the long strip assembly line in the front and rear directions, 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-roll winding is carried out by the return transmission method, which shortens the overall length and avoids the movement influence of the sub-roll transmission on the slitting or sub-roll winding; on the other hand, based on the coordination of the temporary storage movement cycle and the reciprocating shift cycle, without affecting the loading of each sheet, the spindle line sub-roll collection is realized, 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 paths, which greatly reduces the number of post-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 slitting roll material to the winding device based on the connecting roller, and then progress the loading (reprinting separately) of each sheet, and at the same time, based on the loading of the odd and even groups in sequence, avoid the occurrence of adjacent groups of sheets due to the long transmission route. Motion interference; fourthly, the returned sheet can keep the forward sheet relatively aligned, reduce 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 positioning requirements of the transfer roller group and the corresponding returned divided sheet, and based on the online corrector to maintain the smooth output of the sheet; sixthly, based on the three-stage transmission, it not only avoids the change of the sheet entry and exit position affected by the correction adjustment, but also provides favorable conditions for the sheet caching; seventhly, the negative pressure adsorption head forms a motion switching between adsorption and pressure relief, so that the change of the sheet is sufficient to meet the offset requirement of the single-pass winding sheet, and then implements the reciprocating spindle line winding without changing the transfer transmission position of the sheet; 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 seat 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 seat is shifted, the roller seat can be shifted in the width direction.
