Description

  The present invention relates to a sheet cut sticking control method, and in particular, a first transport unit that sequentially feeds an intermediate product at a predetermined pitch, and a second transport unit that continuously feeds a sticking sheet at a speed lower than the feed speed of the intermediate product; The present invention also relates to a sheet cut sticking control method in a cut slip device including an intermittent cut transfer means that cuts a sticking sheet and intermittently transfers the cut sheet and sticks it to each intermediate product.

  When manufacturing absorbent articles such as disposable diapers and sanitary napkins, for example, a landing tape for fixing the diaper at a position corresponding to the waist of the diaper is attached to the back sheet, or a sanitary napkin is attached. An intermittent cutting transfer device may be used as a device for sticking an adhesive tape for preventing displacement to prevent displacement to a back sheet (for example, see Patent Document 1). The intermittent cutting transfer device described in Patent Document 1 supplies a continuous long adhesive sheet so as to be wound around a peripheral surface of an anvil roll between an anvil roll and a rotary cutter that rotate in opposite directions. The long adhesive sheet is cut by bringing the receiving blade provided on the anvil roll into contact with the cutter blade provided on the rotary cutter, and the cut strip-like adhesive sheet is continuously conveyed and supplied. The back sheet is configured to be intermittently transferred and pasted at a predetermined interval.

  In addition, the adhesive sheet after cutting is cut by cutting the adhesive sheet while sliding the adhesive sheet on the peripheral surface of the anvil roll with the supply speed of the long adhesive sheet being slower than the rotation speed of the anvil roll. The sheet can be intermittently conveyed toward the back sheet via the anvil roll.

And according to the intermittent cutting transfer apparatus of patent document 1, when a continuous long adhesive sheet is supplied between an anvil roll and a rotary cutter and an adhesive sheet is cut | disconnected in strip shape, it winds around an anvil roll. The adhesive sheet can be intermittently cut at high speed without causing wrinkles, and the strip-like adhesive sheet after cutting can be intermittently transferred at high speed to the back sheet as the sheet to be adhered.

  On the other hand, when manufacturing absorbent articles such as disposable diapers and sanitary napkins, for example, when attaching release paper coated with adhesive on the wing part of a napkin with wings, or tag tape on individual films covering absorbent articles In the case of attaching an adhesive sheet, it is necessary to transfer and attach an adhesive sheet cut to a length shorter than the length of the intermediate product to each intermediate product of absorbent articles that are sequentially conveyed and supplied. is there. Such a process is different from the case where the pasting sheet is intermittently transferred to the pasting sheet that is continuously conveyed and supplied, such as a back sheet, and the predetermined step is performed at a predetermined position with respect to each intermediate product. Each pasting sheet is pasted by length. Therefore, for example, if there is a gap before the transfer of the sticking sheet to the intermediate product to be sequentially conveyed and supplied, the cut sticking sheet remains in the process without being transferred to the intermediate product. Therefore, in order to avoid such problems, it is desirable to improve the control method of the apparatus.

  The present invention provides an intermediate product that is sent out sequentially while avoiding the sticking sheet remaining in the process without being transferred to the intermediate product even if a missing part occurs in the intermediate product that is sent out sequentially at a predetermined pitch. On the other hand, it aims at providing the sheet cut sticking control method which can each transfer the sticking sheet of shorter length than the said intermediate product easily.

  In the present invention, the first conveying means for sequentially sending the intermediate product at a predetermined pitch, and the adhesive sheet transferred to the intermediate product with a shorter length than the intermediate product are continuously provided at a speed smaller than the delivery speed of the intermediate product. Each intermediate product which is disposed between the first conveying means, the first conveying means and the second conveying means, and cuts the sticking sheet and intermittently transfers the sheet after cutting. A sheet cut sticking control method in a cut slip device including an anvil roll and an intermittent cutting transfer means provided with a rotary cutter, each of which is affixed to the intermediate product, the product upstream of the intermittent cutting transfer means in the delivery direction of the intermediate product A presence / absence detection sensor is provided, and when the missing of the intermediate product is detected, the feeding of the adhesive sheet by the second conveying means is stopped. By providing a sheet cut joining control method for controlling the cut-slip device to emit command is obtained by achieving the above object.

  According to the sheet cut and sticking control method of the present invention, even when an intermediate product sequentially fed out at a predetermined pitch is missing, the sticking sheet is prevented from remaining in the process without being transferred to the intermediate product. On the other hand, it is possible to easily transfer each of the pasted sheets having a shorter length than the intermediate product to the intermediate products that are sequentially sent out.

  FIG. 1 illustrates a configuration of a cut slip device 10 to which a sheet cut and sticking control method according to a preferred embodiment of the present invention is applied. According to this embodiment, when manufacturing the sanitary napkin with a wing as an absorbent article, for example, the cut slip device 10 covers the wing part of the napkin main body 20 that is an intermediate product so that the napkin main body 20 The release paper 21 cut to a length shorter than the length is transferred as a post-cut sheet obtained from the pasting sheet 22 to the napkin main body 20 that is sequentially conveyed and supplied, and the napkin main body 20 to which the release paper 21 is transferred is transferred. , And is transferred to the next process downstream in the delivery direction X.

  The cut slip device 10 includes a first conveying unit 11 that sequentially feeds the napkin body 20 that is an intermediate product at a predetermined pitch, and a pasting before cutting that is transferred to the napkin body 20 with a shorter length than the napkin body 20. The sheet 22 is disposed between the second conveying means 12 that continuously sends out the sheet 22 at a speed V1 that is smaller than the sending speed V0 of the napkin body 20, and the first conveying means 11 and the second conveying means 12, and is pasted. It includes an intermittent cutting transfer means 15 including an anvil roll 13 and a rotary cutter 14 for cutting the sheet 22 and intermittently transferring the release paper 21 which is the cut sheet and affixing it to each napkin body 20.

  The sheet cut sticking control method of the present embodiment is a control method applied to the cut slip device 10 having such a configuration, and the presence / absence of a product on the upstream side of the intermittent cutting transfer means 15 in the feeding direction X of the napkin body 20. A detection sensor 16 is provided, and when the product presence / absence detection sensor 16 detects a lack of the napkin body 20 to be sequentially sent, a cut slip is issued so as to issue a command to stop the feeding of the adhesive sheet 22 by the second conveying means 12 The apparatus 10 is controlled so that the anvil roll 13 and the rotary cutter 14 are idled so as not to cut the sticking sheet 22 or to transport the release paper 21 after cutting.

  Further, according to the present embodiment, the cut slip device 10 includes the feeding speed V0 of the napkin body 20 by the first transporting means 11, the feeding speed V1 of the adhesive sheet 22 by the second transporting means 12, the anvil roll 13 and the rotary cutter 14. Both have a controller 17 for controlling the rotation speed and the like, and a setting machine 18 for calculating and setting the return amount of the sticking sheet 22, the reference speed of the process, the speed ratio of each conveying means 11 and 12, etc. A cutting timing detection sensor 19 that detects the timing of cutting the adhesive sheet 22 by the rotary cutter 14, an adhesive application device 23, and the like are provided.

  The first transport means 11 is provided, for example, by arranging a plurality of conveyor devices 11a in a tandem arrangement in the feed-out direction X. A plurality of napkin bodies 20 formed so as to be cut into the same size are, for example, 100 to 400 mm in length. At a predetermined pitch P, it can be sequentially conveyed and supplied in the delivery direction X at a predetermined speed V0 determined by the setting machine 18, for example, 10 to 200 m / min. Further, the driving roller 11b of each conveyor device 11a is connected to the first servo motor 24 controlled by the controller 17, so that the sending speed V0 can be variably controlled.

  The second conveying means 12 is composed of, for example, a conveyor device 12 a including a suction gripping unit 25, and the driving roller 11 b of the conveyor device 12 a is connected to a second servo motor 26 controlled by the controller 17. By the control, the adhesive sheet 22 is transferred to the intermittent cutting transfer means 15 at a delivery speed V1 which is smaller than the delivery speed V0 by the first conveying means 11 and is proportional to the delivery speed V0 by a proportional constant K of 0 to 1.0. It is designed to be able to carry it continuously. The suction gripping unit 25 has a suction board in which a large number of suction holes arranged along the transport surface of the conveyor device 12a are formed. The suction sheet 22 is attached to the suction board by sucking air inside. The adhering sheet 22 can be continuously pulled out from, for example, an original fabric roll by the conveyor device 12a and fed to the intermittent cutting transfer means 15 while being adsorbed and gripped with a predetermined gripping force.

  Furthermore, according to the present embodiment, the second servo motor 26 that drives the second transport unit 12 has a variable rotational speed, and can stop rotating according to a command from the controller 17. Accordingly, the servo motor can be rotated in the reverse direction to the feed direction, and as such a servo motor, for example, “HC-MFS73” (manufactured by Mitsubishi Electric Corporation) can be preferably used. The second servo motor 26 has a function of detecting the feed speed V0 by the first transport means 11 using a rotary encoder or the like, and is controlled by the controller 17 that also controls the rotational speed of the first servo motor 24. The sticking sheet 22 is sent to the intermittent cutting transfer means 15 at a predetermined speed V1 obtained by multiplying the sending speed V0 of the first transport means 11 by a proportional constant K. Thus, the release paper 21 cut as a post-cut sheet from the pasting sheet 22 by the intermittent cutting transfer means 15 is obtained by multiplying the feeding constant of the napkin body 20 fed by the first transport means 11 by a proportional constant K, for example, 30 It will be cut with a length L of ˜80 mm.

  The anvil roll 13 constituting the intermittent cutting transfer means 15 is a cylindrical rotary roll having a suction and discharge unit 27 inside, and is connected to a third servo motor 28 controlled by the controller 17, and is connected to the rotary cutter 14. At the same time, the peripheral surface moves at the same speed as the feed speed V0 of the first conveying means 11 and is driven to rotate in the direction opposite to the rotary cutter 14. Further, the anvil roll 13 sucks and holds the affixing sheet 22 sent from the second conveying means 12 through the air holes formed in the peripheral surface by sucking the air inside the suction and discharge unit 27, The adhesive sheet 22 is sandwiched between the receiving blade provided on the anvil roll 13 and the cutter blade 29 provided on the rotary cutter 14 for cutting, and the release paper 21 after cutting is intermittently adsorbed and held on the peripheral surface. However, it is conveyed toward the napkin body 20 on the first conveying means 11.

  Further, the anvil roll 13 is arranged at a position where the lower peripheral surface of the anvil roll 13 can come into contact with the upper surface of the napkin main body 20 on the first conveying means 11, and is adsorbed to the peripheral surface. The release paper 21 is discharged from the suction / discharge unit 27 while moving the release paper 21 in the delivery direction X at the same speed as the delivery speed V0 of the napkin body 20 at the lower peripheral surface portion of the anvil roll 13. Is pressed against the napkin main body 20 so that the release papers 21 can be sequentially attached to predetermined positions on the upper surface of the napkin main body 20.

  Here, according to the present embodiment, the feeding speed V1 of the adhesive sheet 22 by the second conveying means 12 is smaller than the moving speed of the peripheral surface of the anvil roll 13 which is the same speed as the feeding speed V0 of the napkin body 20. In addition, the suction gripping force of the pasting sheet 22 by the suction gripping unit 25 of the second conveying means 12 is larger than the suction gripping force of the pasting sheet 22 by the suction discharge unit 27 of the anvil roll 13. Accordingly, the adhesive sheet 22 fed from the second conveying means 12 to the intermittent cutting transfer means 15 is slid on the peripheral surface of the anvil roll 13 until being cut by the rotary cutter 14, and the second conveying means 12. Is continuously supplied at the feed speed V1 and is cut at substantially the same time as being cut, and is moved at the speed V0 of the peripheral surface of the anvil roll 13, whereby the release paper 21 after cutting is The napkin body 20 is intermittently supplied via the peripheral surface of the anvil roll 13.

  The rotary cutter 14 that constitutes the intermittent cutting transfer means 15 together with the anvil roll 13 is a cylindrical rotary roll having a pair of cutter blades 29 arranged at an interval of 180 degrees in the circumferential direction, for example. And the third servo motor 28 controlled by the controller 17, the tip of the cutter blade 29 rotates at the same speed as the feed speed V 0 of the first transport means 11, and synchronizes with the anvil roll 13. And is driven to rotate in the opposite rotation direction. Thereby, the adhesive sheet 22 is cut into a predetermined length on the anvil roll 13 once for each napkin main body 20 sent out by the first conveying means 11. Further, the rotary cutter 14 is provided with a phase machine, for example, so that the speed can be temporarily increased or decreased, and the position of the release paper 21 transferred onto the napkin body 20 is adjusted accordingly. be able to.

  According to this embodiment, the product presence / absence detection sensor 16 arranged upstream of the intermittent cutting transfer means 15 in the delivery direction X of the napkin body 20 can send the detection result of the presence / absence of the product to the controller 17. For example, the trade name “PZ-101” (manufactured by Keyence Corporation) can be preferably used. Further, as the cutting timing detection sensor 19, various known detection sensors that can send the detected cutting timing by the cutter blade 29 to the controller 17 can be used. For example, the product name “E2E-X2E1” (manufactured by OMRON Corporation) ) Can be preferably used.

  According to the present embodiment, as the controller 17 for controlling the servo motors 24, 26, 28, etc. for driving the conveyor devices 11a, 12a, the anvil roll 13 and the rotary cutter 14, for example, the trade name “Q173” (Mitsubishi Electric Corporation) The product name “A950-GOT” (manufactured by Mitsubishi Electric Corporation) can be preferably used as the setting device 18 connected to the controller 17.

  Moreover, according to this embodiment, the adhesive application device 23 has a function capable of intermittently applying the adhesive to the sheet member that is continuously sent out while repeating supply and stop of the adhesive. Various well-known coating devices provided can be used. Here, the adhesive does not necessarily need to be applied to the affixing sheet 22 in the process using the cut slip device 10, and the affixing sheet 22 that has been subjected to an adhesive treatment in a separate process is continuously supplied to the cut slip apparatus 10 and used. Also good.

  And by applying the sheet cut sticking control method of the present embodiment, in the cut slip device 10 having the above-described configuration, the release paper 21 is prevented from remaining in the process without being transferred to the napkin body 20. However, in order to attach the release paper 21 having a predetermined length to a predetermined position of the napkin main body 20 that is sequentially sent out, a product presence / absence detection sensor provided on the upstream side of the intermittent cutting transfer means 15 in the sending direction X. 16, the presence or absence of the napkin main body 20 that is sequentially sent out is monitored, and when the lack of the napkin main body 20 is detected, the controller 17 issues a command to stop the feeding of the adhesive sheet 22 by the second conveying means 12. To control.

  That is, when the lack of the napkin main body 20 to be sequentially sent out by the product presence / absence detection sensor 16 is detected from the normal operating state shown in FIGS. 2A and 2B (see FIG. 1), the information is immediately transmitted to the controller 17. For example, the controller 17 stops the driving of the conveyor device 12a of the second conveying means 12 at the timing when the release paper 21 is cut to the napkin body 20 preceding the missing portion. A command is issued to the servo motor 26.

  As a result, as shown in FIG. 3, the supply of the adhesive sheet 22 is stopped until the missing part of the napkin body 20 passes and the napkin body 20 to be delivered next is detected by the product presence / absence detection sensor 16. Thus, the anvil roll 13 and the rotary cutter 14 of the intermittent cutting transfer means 15 are idled to effectively prevent the release paper 21 from remaining in the process by the cut slip device 10 without being transferred to the napkin body 20. It becomes possible to do.

  Here, after the controller 17 issues a command to stop the driving of the conveyor device 12a of the second conveying means 12, until the second servo motor 26 actually stops as shown in FIG. If there is a time delay, the paste sheet 22 will be sent out after the command for the area indicated by A in FIG. In addition, when the feeding of the sticking sheet 22 by the second conveying means 12 is resumed after the sending is stopped, the sticking sheet 22 cannot be sent out immediately at a predetermined sending speed V1, and therefore the predetermined number of times from the restart of sending. Before the transition to the delivery speed V1, the delivery delay may occur by the area indicated by B in FIG. Due to the delay in the stop and the delay in the delivery, as shown in FIG. 4 (b), the sticking sheet 22 corresponding to the area A is transferred to the missing part of the napkin main body 20, or the napkin main body 20 just after restarting is transferred. There is a possibility that the transfer paper 21 to be transferred becomes smaller by the area of B.

  According to the present embodiment, with respect to these delays, these problems are solved by adding a command that compensates for the delay amount to the speed command of the second conveying means 12 via the second servo motor 26. So that it can be controlled. That is, when stopping, a general servo motor system can obtain the length of the response delay as information in real time. For example, in the setting machine 18, a speed command for returning the delay amount at the stop determination timing. As shown in FIG. 5A, a speed command A for additionally sending back the pasted sheet 22 that has been sent out in the reverse direction is additionally output. The speed of the additionally output speed command A is adjusted so that the second servo motor 26 finishes positioning by the next cutting timing at which the next cutter blade 29 contacts the anvil roll 13.

  At the time of start-up, for example, the setting machine 18 predicts and calculates the delay length generated at that time from the feed speed V1 of the second transport means 12 obtained from the feed speed V0 of the first transport means 11 to determine the start. The speed command B, to which the delay length is added at the timing, is additionally output. The delay length is predicted by calculating the target speed K · V0 and the speed K · V0 of the second servomotor 26 according to the feed speed V0 of the first transport means 11 and the gain setting of the second servomotor 26 of the second transport means 12. This is done by obtaining the position deviation of the second servo motor 26 at. As in the case of the stop, the speed of the additionally output speed command B is adjusted so that the speed of the second servo motor 26 becomes K · V 0 by the next cutting timing.

  And by these controls, the delay of stop and the delay of delivery are effectively compensated, and as shown in FIG. 5 (b), the adhesive sheet 22 is transferred to the part where the napkin body 20 is missing, or immediately after the restart. It becomes possible to effectively avoid the release paper 21 transferred to the napkin body 20 from becoming small.

  Further, according to the present embodiment, the cut slip device 10 uses the suction gripping unit 25 of the second conveying means 12 by the cutting frictional force at the moment of cutting of the pasting sheet 22 due to, for example, deterioration of the cutter blade 29 of the rotary cutter 14. The suction and gripping force by the suction / discharge unit 27 of the anvil roll 13 is superior to the suction and gripping force, and an extremely short sheet may be pulled out every time it is cut. As a result, even if the second conveying means 12 is stopped after the sticking sheet 22 is cut, a very short sheet 30 is continuously cut out as shown in FIG. The device may be contaminated or mixed into the product.

  According to this embodiment, in order to avoid the occurrence of such an extremely short sheet 30, control is performed to send back the pasted sheet 22 that has been pulled out excessively. That is, for example, when the driving of the second conveying means 12 by the second servomotor 26 is stopped, in view of the cutting frictional force of the cutter blade 29, the feeding speed V1 of the sticking sheet 22, etc. As shown in FIG. 6 (b), the additional length for securing the feed back length before the next cutter blade 19 comes into contact with the anvil roll 13 so as to obtain a feed back length of 1 to 5 mm. Speed command A ′ is output. Further, when restarting the feeding of the adhesive sheet 22 by the second transporting means 12, the delay of the feeding due to the feeding back is output at a speed faster than the feeding speed V1 by outputting an additional speed command A '. Thus, the amount of reverse rotation for sending back at the time of stop is controlled so as to send out more. And generation | occurrence | production of the very short sheet | seat 30 can be effectively avoided by these.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, the present invention is not limited to the case where a release paper is attached to the wing portion of a napkin with a wing, and other various absorbent biological products in which a sheet material shorter than this is pasted to an intermediate product are manufactured. Can also be adopted. Moreover, you may comprise a 1st conveying means and a 2nd conveying means with conveying apparatuses other than a conveyor apparatus. Further, as the means for driving the first conveying means and the second conveying means, various other driving devices such as a stepping motor can be adopted in addition to the servo motor.
