Description

  The present invention relates to a transport device for transporting a transport target member to be transported.

  Conventionally, for example, the conveyance device described in Patent Literature 1 is attached to a rotation shaft and the rotation shaft so as to be rotatable in accordance with the rotation of the rotation shaft, and each member to be conveyed (processed product) is provided. A plurality of holding mechanisms (swivel units) to be held, and a speed change mechanism (transmission unit) that changes the angular velocity of each holding mechanism while each holding mechanism rotates about the rotation axis.

  The plurality of holding mechanisms are arranged at different angles around the rotation axis. The speed change mechanism changes the angular velocity of the two holding mechanisms so that an angle difference is generated between two holding mechanisms adjacent to each other among the plurality of holding mechanisms. Accordingly, the distance between the two holding mechanisms changes according to the difference in angular velocity between the two holding mechanisms.

  Here, when foreign matter such as dust or dust enters a gap between two holding mechanisms adjacent to each other, this foreign matter is a mechanism provided between the two holding mechanisms (the holding mechanism is rotated about the rotation axis). There is a possibility that the transport device may not operate normally due to an adverse effect on a mechanism that can be supported.

  Therefore, the transport device described in Patent Literature 1 includes a cover attached to the two holding mechanisms so as to cover a gap between two adjacent holding mechanisms from the outside in the radial direction of the rotation shaft. . This cover is formed in a bellows shape that can be expanded and contracted in accordance with a change in the distance between two holding mechanisms adjacent to each other.

Japanese Patent No. 4054191 (particularly FIG. 3)

  However, when a bellows-like cover is provided between the two holding mechanisms, when the two holding mechanisms approach each other, the cover is not folded as planned, and a part of the cover has a diameter of the rotation shaft. There is a risk of jumping inward or outward in the direction.

  As a result, when the cover comes into contact with the surrounding structure, the cover may be damaged, and the function as the cover may not be effectively performed.

  An object of the present invention is to provide a transport device that can more effectively prevent foreign matter from entering between the two holding mechanisms regardless of the distance between the two holding mechanisms adjacent to each other, and disposable wear using the same. The object is to provide a method for manufacturing an article.

  In order to solve the above-described problems, the present invention is a transport device for transporting a transport target member to be transported, and the rotation shaft and the rotation so as to be rotatable according to the rotation of the rotation shaft. A plurality of holding mechanisms attached to a shaft and capable of holding each of the conveyance target members and arranged at different angles around the rotation shaft; and two adjacent ones of the plurality of holding mechanisms A transmission mechanism that changes angular velocities of the plurality of holding mechanisms so as to cause an angle difference between the holding mechanisms, and a gap between the two holding mechanisms so as to cover from the outside in the radial direction of the rotating shaft. At least one first cover extending from one first holding mechanism of the two holding mechanisms toward the other second holding mechanism of the two holding mechanisms, and covering the gap from outside in the radial direction And at least one second cover extending from the second holding mechanism toward the first holding mechanism and overlapping the first cover in the radial direction, wherein the first cover and the second cover are Provided is a transport device having a length that allows two holding mechanisms to overlap each other in the radial direction in a state where the two holding mechanisms are farthest apart.

  According to the present invention, the first cover and the second cover respectively extending from the two holding mechanisms adjacent to each other overlap each other in the radial direction. Thus, unlike the conventional bellows-like cover that deforms according to the variation in the distance between the two holding mechanisms, the gap between the two holding mechanisms is maintained in the radial direction while maintaining the shapes of the first cover and the second cover. Can be covered from the outside.

  In the present invention, since both covers have such a length that they can overlap each other in the radial direction in a state where the two holding mechanisms are farthest apart, the two holding mechanisms are changed even if the distance between the two holding mechanisms varies. It is possible to prevent foreign matter from entering the gap between them.

  Therefore, according to the present invention, it is possible to more effectively prevent foreign matter from entering between the two holding mechanisms regardless of the distance between the two holding mechanisms adjacent to each other.

  Here, the first cover and the second cover may be in contact with each other in the radial direction, but in this case, both the covers are rubbed in accordance with a change in the distance between the two holding mechanisms, so that the consumption of both the covers is performed. Is big.

  Therefore, in the transport device, it is preferable that the first cover and the second cover are separated from each other in the radial direction.

  According to this aspect, it is possible to prevent the sliding of both covers due to the relative displacement of the two holding mechanisms, and therefore, it is possible to reduce the wear of both the covers.

  Here, when both covers are separated from each other in the radial direction as described above, foreign matter may enter between the two holding mechanisms through a gap between the covers.

  Therefore, the transport device further includes a sandwiching member sandwiched in the radial direction between the first cover and the second cover, and the sandwiching member is in a state where the two holding mechanisms are farthest apart. It is preferable that the first cover and the second cover are provided only in a region overlapping each other in the radial direction.

  According to this aspect, the sandwiched member that is sandwiched between the covers in the radial direction is provided only in a region that overlaps in the radial direction of both covers in a state where the two holding mechanisms are farthest apart. Therefore, it is possible to minimize the increase in sliding resistance due to the provision of the sandwiched member while preventing foreign matter from entering through the gap between the covers.

  Here, the plurality of holding mechanisms include a holding pad for holding the conveyance target member, a turning shaft extending from the holding pad toward the inside in the radial direction, and a turning cam follower attached to the turning shaft, And the transfer device guides the turning cam follower so that the holding pad can turn around the turning axis according to the rotation of the plurality of holding mechanisms around the rotation axis. If the structure further includes the turning cam having the guide surface, the object to be transferred held by the holding pad can be turned around the turning axis while being conveyed around the rotation axis.

  However, in this case, if a foreign object enters between the turning cam follower and the turning guide surface, the turning cam follower cannot be accurately guided.

  Therefore, in the transport apparatus, it is preferable that the turning guide surface has a portion covered from the outside in the radial direction by the first cover and the second cover.

  According to this aspect, since the turning guide surface can be covered by the two covers from the outside in the radial direction, it is possible to prevent foreign matter from entering between the turning cam follower and the turning guide surface.

  In particular, all of the plurality of holding mechanisms include the first cover and the second cover, and the entire turning guide surface includes all of the plurality of holding mechanisms, all of the first covers, and It is preferable that the second cover is covered from the outside in the radial direction.

  According to this aspect, since the entire turning guide surface can be covered from the outside in the radial direction by the holding mechanism and both covers, it is possible to more reliably prevent foreign matter from entering between the turning cam follower and the turning guide surface. Can be prevented.

  Here, when the turning guide surface is covered only from the outside in the radial direction, foreign matter enters between the turning cam, the holding mechanism, the first cover, and the second cover along the axial direction of the rotating shaft. There is a risk.

  Therefore, the conveying device is provided on both sides of the turning cam in the axial direction of the rotating shaft, and is between all of the plurality of holding mechanisms, all of the first cover, and all of the second cover. It is preferable that the apparatus further includes a pair of covering members that form a covering chamber covered from the outside in the radial direction and from both sides in the axial direction, and the turning guide surface is provided in the covering chamber.

  According to this aspect, since the turning guide surface can be covered from both sides in the axial direction by the pair of covering members, it is possible to prevent foreign matter from entering along the axial direction between the turning guide surface and the cam follower. It can be surely prevented.

  Here, since the plurality of holding mechanisms may rotate at different angular velocities, the pair of covering members provided on both sides in the axial direction of the plurality of holding mechanisms are the holding mechanism, the first cover, and the second cover. It is necessary to allow relative displacement in the rotation direction around the rotation axis. However, in this case, a clearance is required between the covering member, the holding mechanism, the first cover, and the second cover in order to allow the relative displacement, and foreign matter can be prevented from entering through the clearance. It ’s difficult.

  Therefore, it is preferable that the transport device further includes a filter for capturing foreign matter and an outside air introduction unit capable of introducing outside air into the coating chamber via the filter.

  According to this aspect, since the outside air through the filter can be introduced into the coating chamber, even if the clearance as described above is formed, the air in the coating chamber is led out through this clearance. It is possible to prevent foreign matter from entering the coating chamber through the clearance.

  Here, although the transmission mechanism may be provided in the coating chamber, the transmission mechanism may be inevitably provided outside the coating chamber in the axial direction due to the configuration of the transport device.

  In this case, in the transfer device, the transfer device covers the transmission mechanism from the side opposite to the coating chamber and the outside in the radial direction in the axial direction, and further includes a rotary shaft side cover fixed to the rotary shaft. It is preferable to provide.

  According to this aspect, the speed change mechanism provided outside the coating chamber can be covered by the rotating shaft side cover from the side opposite to the coating chamber in the axial direction (one side in the axial direction) and the outside in the radial direction. Further, since one covering member exists on the opposite side of the transmission mechanism from the rotation shaft side cover in the axial direction, the transmission mechanism can also be covered from the other side in the axial direction by the covering member. Therefore, it is possible to suppress the occurrence of an abnormality in the operation of the speed change mechanism due to foreign matters adhering to the speed change mechanism.

  In addition, since the rotating shaft side cover is fixed to the rotating shaft, the weight of the holding mechanism can be reduced, whereby the transport speed of the transport target member can be improved.

  Further, the present invention is a method for manufacturing a disposable wearing article having a waistline portion disposed around a wearer's waist and a crotch portion disposed at a wearer's inseam using the transport device, wherein the waistline A waistline sheet transporting step for transporting a waistline sheet for forming a section along the longitudinal direction thereof, and a crotch member provided in a portion corresponding to the crotch part to the waistline sheet using the transport device A crotch member joining step for conveying and forming the joined body by joining the inseam member to the waistline sheet, and a two-folding step for folding the joined body in the width direction perpendicular to the longitudinal direction A side sealing step of joining the overlapping portions of the waistline sheet on both sides of the crotch member in the longitudinal direction to form a side seal, and in the longitudinal direction To provide a method of manufacturing a disposable wearing article comprising a cutting step of forming a disposable wearing article by cutting the waist sheet as side seal remains on both sides of the crotch member.

  According to the manufacturing method according to the present invention, the crotch member is formed into the waistline sheet by using the conveying device that can prevent foreign matter from entering the gap between the two holding mechanisms as described above. Can be transported.

  Then, the crotch member is joined to the waistline sheet to form a joined body, the joined body is folded in half, a side seal is formed on the joined body, and the waistline sheet is cut, thereby disposing the disposable wearing article. Can be manufactured.

  Therefore, according to the manufacturing method which concerns on this invention, since the malfunctioning of a conveying apparatus can be reduced, the manufacturing efficiency of a disposable wearing article can be improved by using this conveying apparatus for manufacture of a disposable wearing article. it can.

  According to the present invention, it is possible to more effectively prevent foreign matter from entering between the two holding mechanisms regardless of the distance between the two holding mechanisms adjacent to each other.

Further, as shown in FIGS. 2 and 3, the cam groove 33b is a portion formed along a path in which the position in the direction along the rotation center C changes in accordance with the change in the position around the rotation center C. Have

  The rotation mechanism 12 has a rotation shaft 15 supported by the fixing mechanism 13 so as to be rotatable about the rotation center C. Specifically, the rotary shaft 15 passes through the bottom plate portion 31a of the fixed drum 31 and the cam main body 32a of the speed change cam 32, and is rotatably supported by the bearing B1 with respect to the bottom plate portion 31a. On the other hand, it is rotatably supported by bearings B2 and B3.

  Further, the rotating mechanism 12 is attached to the rotating shaft 15 so as to be rotatable in accordance with the rotation of the rotating shaft 15, and ten holding mechanisms 19 arranged at different positions around the rotating shaft 15. It has.

  Further, the rotation mechanism 12 has the following configuration in order to support the holding mechanism 19 so as to be rotatable according to the rotation of the rotation shaft 15.

  Specifically, the rotation mechanism 12 includes a rotation support body 16 fixed to the distal end portion of the rotation shaft 15, ten arms 17 attached to the rotation support body 16, and a link lever 18 attached to each arm 17. (That is, ten link levers 18) and support members 20 and 21 that are rotatably attached to the fixed drum 31.

  The rotary support 16 is a disk-shaped member provided on the tip side of the turning cam 33.

  The arm 17 includes an arm main body 17a attached to the outer edge of the rotation support 16 and the link lever 18, and extends from the arm main body 17a to the base end side (right side in FIG. 4) and into the cam groove 32b of the speed change cam 32. And an inserted cam follower 17d. The arm body 17a has a first end attached to the rotary support 16 so as to be rotatable about the shaft 17b, and a second end attached to the link lever 18 so as to be rotatable about the shaft 17c. And having. The shafts 17b and 17c are shafts extending in parallel with the rotation center C. The cam follower 17d is attached to the arm main body 17a so as to be rotatable about an axis parallel to the rotation center C, and this axis is provided at a position different from the axis 17b in the front view shown in FIG. Therefore, when the rotary shaft 15 is rotating, the position of the cam follower 17d in the cam groove 32b changes, so that the arm body 17a rotates with respect to the rotary support 16 about the shaft 17b.

  The link lever 18 has a lever body 18 a attached to the arm 17 and the holding mechanism 19. The lever main body 18a has a first end attached to the arm main body 17a so as to be rotatable about the shaft 17c, and a second end attached to the holding mechanism 19 so as to be rotatable about the shaft 18b. And having an end. The axis 18b is an axis extending in parallel with the rotation center C.

  3 and 4, the support member 20 includes a donut-shaped support plate 20a rotatably attached to the cylindrical portion 31b of the fixed drum 31 via a bearing B4, and an outer edge portion of the support plate 20a. And a rail 20b attached to a surface facing the front end side of the support plate 20a. The support plate 20a is provided on the distal end side (left side in the figure) of the turning cam 33. The rail 20b is provided along a circular path centered on the rotation center C.

  Similarly, the support member 21 includes a donut-shaped support plate 21a rotatably attached to the cylindrical portion 31b of the fixed drum 31 via a bearing B5, and the support plate 21a along the outer edge portion of the support plate 21a.

  Sliders 26d and 26e provided on the holding mechanism 19 are engaged with the rails 20b and 21b of the support members 20 and 21, respectively. Accordingly, the holding mechanism 19 is allowed to move along a circular path defined by the rails 20b and 21b, and is restricted from moving in other directions.

  Therefore, when the rotation shaft 15 rotates and the angle of the arm 17 with respect to the rotation support 16 changes, the holding mechanism 19 connected to the arm 17 via the link lever 18 is defined by the rails 20b and 21b. It moves with respect to the rotating shaft 15 along a circular path. Thereby, the angular velocity of the holding mechanism 19 changes.

  Specifically, in FIG. 2, when the rotary shaft 15 rotates clockwise around the rotation center C, the cam follower 17d is guided along the cam groove 32b. Thereby, for example, the arm 17 connected to the holding mechanism 19 at the take-over position for receiving the absorber A from the delivery roller 5 is gradually inclined in the rotation direction of the rotary shaft 15 with respect to the rotary support 16 (arm 17 And the inner angle with the link lever 18 is gradually narrowed). As a result, the holding mechanism 19 is pulled in the rotation direction by the link lever 18 with respect to the rotary support 16 (rotating shaft 15), that is, the holding mechanism 19 is accelerated. This acceleration period continues until just before the delivery position at which the absorber A is delivered to both sheets S1, S2 positioned between the conveying device 10 and the take-up roller 6, and a holding mechanism in the region from this position to the delivery position. 19 rotates at a constant speed.

  When the rotation shaft 15 further rotates, the arm 17 connected to the holding mechanism 19 at the delivery position gradually inclines in the direction opposite to the rotation direction with respect to the rotation support 16 (the inner angle between the arm 17 and the link lever 18). Gradually spread). As a result, the holding mechanism 19 is pushed to the rotation support 16 (rotating shaft 15) by the link lever 18 in the direction opposite to the rotation direction, that is, the holding mechanism 19 is decelerated. This deceleration period continues until just before the delivery position, and the holding mechanism 19 rotates at a constant speed in the region from this position to the delivery position.

  As described above, in this embodiment, the speed change cam 32, the arm 17, and the link lever 18 are set so that an angular difference is generated between two holding mechanisms 19 adjacent to each other among the ten holding mechanisms 19. This corresponds to a speed change mechanism that changes the angular velocity of each holding mechanism 19.

  Each holding mechanism 19 is capable of holding the absorber A delivered from the delivery roller 5 and is positioned between each holding mechanism 19 and the receiving roller 6 after the absorber A is turned 90 °. The absorbent body A is delivered to both sheets S1 and S2.

  Specifically, as shown in FIGS. 2 to 4, each holding mechanism 19 includes a drive base 26 connected to the above-described transmission mechanism, and a holding pad attached to the drive base 26 via a turning shaft 28. 27, a lever 29 attached to the turning shaft 28, and a cam follower (turning cam follower) 30 attached to the lever 29.

  The drive base 26 is an outer wall portion 26 a provided outside the turning cam 33, the support members 20 and 21, the arm 17, and the link lever 18 described above in the radial direction of the rotation shaft 15 (direction orthogonal to the rotation center C). And supported portions 26b and 26c protruding radially inward from the outer wall portion 26a, and sliders 26d and 26e provided on the supported portions 26b and 26c. The link lever 18 is rotatably attached to the tip-side surface of the tip-side supported portion 26b via a shaft 18b. Further, a slider 26d engaged with the rail 20b described above is provided on the base end side surface of the supported portion 26b. On the other hand, a slider 26e engaged with the rail 21b described above is provided on the surface on the base end side of the supported portion 26c on the base end side.

  The holding pad 27 has a holding surface that faces the outside in the radial direction of the rotary shaft 15 and can hold the absorber A. Specifically, a suction hole (not shown) is formed in the holding surface of the holding pad 27, and the absorber A is sucked into the holding surface by sucking air outside the holding surface through the suction hole. Is adsorbed. In FIG. 2, the holding surface of the holding pad 27 is formed flat, but the shape of the holding surface is not particularly limited.

  The pivot shaft 28 extends from the holding pad 27 toward the inside in the radial direction of the rotary shaft 15 and penetrates the outer wall portion 26 a of the drive base 26. Further, the turning shaft 28 is supported by the outer wall portion 26 a so as to be rotatable about an axis along the radial direction of the rotating shaft 15.

  The lever 29 is fixed to the inner end of the turning shaft 28 in the radial direction of the rotating shaft 15. The lever 29 extends in a direction orthogonal to the turning center of the turning shaft 28.

  The cam follower 30 is provided at the tip of the lever 29 so as to be rotatable about an axis parallel to the turning shaft 28. The turning shaft 28 and the rotation shaft of the cam follower 30 are provided at different positions on a plane orthogonal to the turning shaft 28. The cam follower 30 extends from the lever 29 toward the inside in the radial direction of the rotating shaft 15 and engages with the cam groove 33 b of the turning cam 33.

  Therefore, the cam follower 30 is guided along the inner surface (the turning guide surface) of the cam groove 33b according to the rotation of the rotating shaft 15. Specifically, the cam follower 30 is guided by the cam groove 33 b so that the holding pad 27 can turn around the turning shaft 28 in accordance with the rotation of the holding mechanism 19 around the rotating shaft 15. As a result, the absorbent body A held by the holding pad 27 is turned by 90 ° before it is conveyed from the delivery roller 5 to the take-up roller 6.

  In the transport device 10 configured as described above, the size of the gap between the two holding mechanisms 19 adjacent to each other is changed by the speed change mechanism (the speed change cam 32, the arm 17, and the link lever 18). To do. In the present embodiment, since the turning cam 33 is provided in the gap between the holding mechanisms 19, if foreign matter such as dust or dust enters the gap from the outside in the radial direction of the rotating shaft 15, the cam follower There is a possibility that foreign matter may be caught between the cam 30 and the cam groove 33b and the turning operation of the holding pad 27 may be abnormal.

  Therefore, as illustrated in FIGS. 5 to 7, the transport device 10 includes a first cover 22 that extends from one first holding mechanism of two holding mechanisms 19 adjacent to each other toward the other second holding mechanism. And a second cover 23 extending from the second holding mechanism toward the first holding mechanism. A gap between the two holding mechanisms 19 is covered from the outside in the radial direction of the rotating shaft 15 by both covers 22 and 23.

  In the present embodiment, all the holding mechanisms 19 have a first cover 22 and a second cover 23. Since the first cover 22 and the second cover 23 all have the same configuration, only one set of the first cover 22 and the second cover 23 will be described.

  Specifically, the first cover 22 includes an attachment portion 22a attached to the outer wall portion 26a of the drive base 26 of the first holding mechanism, a cover portion 22b extending from the attachment portion 22a toward the second holding mechanism, and an attachment portion. And a reinforcing rib 22c provided across the cover 22a and the cover 22b.

  Similarly, the second cover 23 includes an attachment portion 23a attached to the outer wall portion 26a of the drive base 26 of the second holding mechanism, a cover portion 23b extending from the attachment portion 23a toward the first holding mechanism, and an attachment portion 23a. And a reinforcing rib 23c provided over the cover portion 23b.

  The cover portion 22b of the first cover 22 and the cover portion 23b of the second cover 23 have a length that overlaps with each other in the radial direction of the rotary shaft 15 in a state where the two adjacent holding mechanisms 19 are farthest from each other. Specifically, the cover 22b overlaps the outer side of the cover 23b in the radial direction.

  Further, the cover 22 b of the first cover 22 and the cover 23 b of the second cover 23 are separated from each other in the radial direction of the rotary shaft 15. Thereby, when the two holding mechanisms 19 approach each other and move away from each other, it is possible to prevent the sliding resistance between the cover portions 22b and 23b from occurring.

  On the other hand, if the cover portions 22b and 23b are separated from each other in the radial direction of the rotary shaft 15, foreign matter may enter from between the cover portions 22b and 23b. Therefore, in order to prevent this foreign substance from entering, the rotation mechanism 12 of the transport device 10 is sandwiched between the cover portions 22b and 23b in the radial direction of the rotation shaft 15 (in the hatching of FIG. 7). Member).

  The sandwiched member 7 is provided only in a region where the two holding mechanisms 19 adjacent to each other are separated from each other in the radial direction of the first cover 22 and the second cover. Specifically, as shown in FIG. 7, the sandwiched member 7 is provided only at the tip of the cover 23 b of the second cover 23 (the end close to the first holding mechanism). Thereby, intrusion of a foreign substance can be prevented while preventing the occurrence of the sliding resistance described above. The sandwiched member 7 can be formed of felt, for example.

  As shown in FIG. 3, the outer wall portion 26 a of the holding mechanism 19 to which both the covers 22 and 23 are attached is disposed so as to cover the cam groove 33 b from the outside in the radial direction of the rotating shaft 15. Therefore, the entire cam groove 33 b is covered from the outside in the radial direction of the rotary shaft 15 by all the holding mechanisms 19, all the first covers 22, and all the second covers 23.

  3 and 4, the pair of support members 20 and 21 described above are provided on both sides of the turning cam 33 in the axial direction of the rotating shaft 15, and all the holding mechanisms 19 and all the first covers 22 are provided. , And a pair of covering members that form a covering chamber R1 that is covered between the second cover 23 and the outer side in the radial direction of the rotary shaft 15 and from both sides of the rotary shaft 15 in the axial direction.

  Specifically, the support member 21 includes an outer peripheral cover 21 c that covers a gap between the support plate 21 a and the drive base 26 of the holding mechanism 19 from the radially outer side of the rotary shaft 15. The outer periphery cover 21c is provided over the entire periphery centering on the rotating shaft 15 along the outer periphery of the support plate 21a. The covering chamber R <b> 1 is partitioned by a support plate 20 a of the support member 20, a support plate 21 a and an outer peripheral cover 21 c of the support member 21, a drive base 26, a first cover 22, and a second cover 23.

  The cam groove 33b of the turning cam 33 is provided in the coating chamber R1.

  The support member 20 also includes an outer peripheral cover 20c that covers the gap between the support plate 20a and the supported portion 26b from the outside in the axial direction of the rotary shaft 15. The outer peripheral cover 20 c and the outer peripheral cover 21 c cover the rails 20 b and 21 b and the sliders 26 d and 26 e from the outside in the radial direction of the rotating shaft 15, respectively.

  As shown in FIG. 3, the first cover 22 and the second cover 23 extend from the position of the end face on the proximal end side of the outer peripheral cover 20c to the position of the end face on the distal end side of the outer cover 21c in the axial direction of the rotary shaft 15. It is provided over the region.

  Here, since the holding mechanism 19 rotates at different angular velocities, the support members 20 and 21 provided on both sides in the axial direction of the holding mechanism are supported by the rails 20b and 21b and the sliders 26d and 26e as described above. A relative displacement in the rotation direction around the rotation shaft 15 with respect to the holding mechanism 19 and the covers 22 and 23 is allowed. However, in this case, a clearance is required between the support members 20 and 21 and the holding mechanism 19 and the covers 22 and 23 in order to allow relative displacement, and foreign matter can be prevented from entering through the clearance. It ’s difficult.

  Therefore, the fixed drum 31 of the transport apparatus 10 can introduce outside air into the coating chamber R1 through the filter 31e for capturing foreign matter as shown in FIG. 4 and the filter 31e as shown by the arrow in FIG. Fan (outside air introduction means) 31c. The filter 31e and the fan 31c are provided in a through hole 31d formed in the bottom plate portion 31a. The through hole 31d opens in the cylindrical portion 31b. Therefore, when the fan 31c is operated, air is introduced into the cylindrical portion 31b through the through hole 31d, and is further covered through a hole formed in the cylindrical portion 31b (shown by a two-dot chain line in FIG. 4). Guided into chamber R1. Thereby, even if the clearance as described above is formed, it is possible to prevent foreign matter from entering the coating chamber R1 by leading the air through the clearance.

  Further, since the air introduced into the cylindrical portion 31b of the fixed drum 31 by the fan 31c passes near the bearings B4 and B5 that rotatably support the support members 20 and 21 on the cylindrical portion 31b, these bearings. B4 and B5 can also be cooled. Thereby, the thermal expansion of the bearings B4 and B5 (outer ring and inner ring) accompanying the temperature rise of the bearings B4 and B5 can be suppressed, and the operation of the holding mechanism 19 can be stabilized.

  As described above, the speed change mechanism (the speed change cam 32, the arm 17, and the link lever 18) has a covering chamber in the front end side (left side in FIG. 4) of the support member 20 on the front end side, that is, in the axial direction of the rotary shaft 15. It is provided outside R1 (left side in FIG. 4).

  Therefore, as shown in FIGS. 3 to 5, the rotation mechanism 12 of the transport apparatus 10 covers the transmission mechanism from the opposite side of the coating chamber R1 in the axial direction of the rotation shaft 15 and from the outer side in the radial direction of the rotation shaft 15, A rotation shaft side cover (reference numeral omitted) fixed to the rotation shaft 15 is provided.

  The rotation shaft side cover is arranged along the outer peripheral edge of the rotation support 16 and has a plurality of inner covers 24 each having a fan shape fixed to the outer periphery of the rotation support 16, and the outer periphery of each inner cover 24. And two outer covers 25 that are detachably attached.

  The inner cover 24 is a plate material extending along a plane orthogonal to the rotation center C, and covers the speed change mechanism, in particular, the arm 17 and the speed change cam 32 in a direction parallel to the axial direction of the rotary shaft 15.

  The outer cover 25 includes a side wall portion 25a extending from the outer peripheral edge of the inner cover 24 to the outer side in the radial direction of the rotary shaft 15, and a base end side in the axial direction of the rotary shaft 15 from the outer peripheral edge of the side wall portion 25a (right side in FIG. 4). And a peripheral wall portion 25b extending to the plate. The side wall portion 25 a is a portion extending along a plane orthogonal to the rotation center C, and covers the speed change mechanism, particularly the arm 17 and the link lever 18 in a direction parallel to the axial direction of the rotation shaft 15. The peripheral wall portion 25 b is a portion extending along an arc surface centered on the rotation center C, and covers the speed change mechanism, particularly the arm 17 and the link lever 18 from the outside in the radial direction of the rotation shaft 15.

  Referring to FIG. 4, the drive mechanism 14 includes a motor 34, a drive shaft 35 that is rotationally driven by the motor 34, a shaft-side drive pulley 36 that is fixed to the drive shaft 35, and a shaft side that is fixed to the rotary shaft 15. A driven pulley 37 and a belt (reference numeral omitted) indicated by a two-dot chain line spanned between the shaft-side drive pulley 36 and the shaft-side driven pulley 37 are provided. As the drive shaft 35 is rotated by the motor 34, the power of the motor 34 is transmitted to the rotary shaft 15 via the belt.

  Here, the support members 20 and 21 support the ten holding mechanisms 19 in a rotatable manner, and may be fixed regardless of the drive of the rotary shaft 15 (fixed to the support plate 11). May be) However, the ten holding mechanisms 19 rotate at different speeds as described above. For this reason, when the support members 20 and 21 are fixed, forces having different vectors are simultaneously applied to the support members 20 and 21 as the ten holding mechanisms 19 rotate. There is a problem that the shifting cam 32 and the cam follower 17d deteriorate due to the concentration on the cam 32 and the cam follower 17d.

  Therefore, the drive mechanism 14 rotates both the support members 20 and 21 in synchronization with the rotation shaft 15.

  Specifically, the drive mechanism 14 includes a support-side drive pulley 38 fixed to a shaft (reference numeral omitted) connected to the drive shaft 35 by a pulley and a belt (not shown), and a support member 21 on the base end side. A support-side driven pulley 39 fixed to the support plate 21a, and a belt (reference numeral omitted) indicated by a two-dot chain line spanned between the support-side drive pulley 38 and the support-side driven pulley 39. When the drive shaft 35 is rotated by the motor 34, the power of the motor 34 is transmitted to the support member 21 via the belt.

  The drive mechanism 14 further includes an angle 26 f that connects the support plate 20 a of the support member 20 on the distal end side and the rotation support 16. As a result, the power of the motor 34 is transmitted to the support member 20 via the rotary shaft 15 and the rotary support 16.

  Since both the support members 20 and 21 are rotationally driven in synchronization with the rotation shaft 15 in this way, the force applied to the both support members 20 and 21 is relative to the rotation shaft 15 by the ten holding mechanisms 19. Since the force is reduced according to the speed difference, the deterioration of the shift cam 32 and the cam follower 17d described above can be reduced.

  As described above, the first cover 22 and the second cover 23 extending from the two holding mechanisms 19 adjacent to each other overlap each other in the radial direction. Thus, unlike the conventional bellows-shaped cover that deforms according to the variation in the distance between the two holding mechanisms 19, the shape between the two holding mechanisms 19 is maintained while maintaining the shapes of the first cover 22 and the second cover 23. The gap can be covered from the outside in the radial direction.

  In addition, since both covers 22 and 23 have such a length that they can overlap each other in the radial direction with the two holding mechanisms 19 being farthest apart, the two holding mechanisms 19 can be maintained even if the distance between the two holding mechanisms 19 varies. Foreign substances can be prevented from entering the gap between the mechanisms 19.

  Therefore, foreign matter can be more effectively prevented from entering between the two holding mechanisms 19 regardless of the distance between the two holding mechanisms 19 adjacent to each other.

  Moreover, according to the said embodiment, there can exist the following effects.

  Both covers 22 and 23 are separated from each other in the radial direction of the rotary shaft 15. Thereby, since the sliding of both the covers 22 and 23 accompanying the relative displacement of the two holding mechanisms 19 can be prevented, the wear of both the covers 22 and 23 can be reduced.

  The sandwiched member 7 that is sandwiched between the covers 22 and 23 in the radial direction is provided only in a region that overlaps in the radial direction of the covers 22 and 23 in a state where the two holding mechanisms 19 are farthest apart. Therefore, it is possible to minimize an increase in sliding resistance caused by providing the sandwiched member 7 while preventing foreign matter from entering through the gap between the covers 22 and 23.

  Since the entire cam groove (turning guide surface) 33b can be covered from the outside in the radial direction of the rotary shaft 15 by the holding mechanism 19 and the covers 22, 23, foreign matter enters between the cam follower 30 and the cam groove 33b. It can prevent more reliably.

  Since the cam groove 33b can be covered from both sides in the axial direction of the rotary shaft 15 by the pair of support members (covering members) 20 and 21, foreign matter is generated along the axial direction between the cam groove 33b and the cam follower 30. Intrusion can be reliably prevented.

  According to this aspect, the outside air that has passed through the filter 31e can be introduced into the coating chamber R1. Therefore, even when a clearance is formed between the support members 20 and 21 and the holding mechanism 19 and the covers 22 and 23, through the clearance, the air in the coating chamber R1 is led through the clearance. It is possible to prevent foreign matter from entering the coating chamber R1.

  A transmission mechanism (transmission cam 32, arm 17, and link lever 18) provided outside the coating chamber R1 is covered with a rotary shaft side cover (an inner cover 24 and an outer cover 25) in the axial direction of the rotary shaft 15. And the opposite side (one side in the axial direction) and the outside in the radial direction. Further, since one support member 20 exists on the opposite side of the rotation shaft 15 to the rotation shaft side cover in the axial direction of the rotation shaft 15, the transmission mechanism can also be covered by the support member 20 from the other side in the axial direction. . Therefore, it is possible to suppress the occurrence of an abnormality in the operation of the speed change mechanism due to foreign matters adhering to the speed change mechanism.

  Moreover, since the rotating shaft side cover is fixed to the rotating shaft 15, the holding mechanism 19 can be reduced in weight, thereby improving the conveyance speed of the absorbent body A.

  Since the malfunction of the transport apparatus 10 can be reduced as described above, the manufacturing efficiency of the disposable diaper 1 can be improved by using the transport apparatus 10 for manufacturing the disposable diaper 1.

  In addition, this invention is not limited to the said embodiment, For example, the following aspects can also be employ | adopted.

  Although an example in which the covers 22 and 23 are separated from each other in the radial direction of the rotary shaft 15 has been described, the covers 22 and 23 may be in contact with each other in the radial direction. In this case, the sandwiched member 7 can be omitted.

  The example in which the entire cam groove (swing guide surface) 33b is covered from the outside in the radial direction of the rotating shaft by the holding mechanism 19 and the covers 22 and 23 has been described. However, at least a part of the cam groove 33b is covered by the covers 22. , 23 may be covered from the outside in the radial direction. Thereby, the bad influence which a foreign material has on the turning operation | movement of the holding pad 27 can be reduced.

  Although the example which covers the cam groove 33b from the both sides of the axial direction of the rotating shaft 15 by the supporting members (a pair of covering members) 20 and 21 has been described, at least one of the supporting members 20 and 21 can be omitted.

  Although the example which has the filter 31e and the fan 31c was demonstrated, these can also be abbreviate | omitted.

  Although the example in which the speed change mechanism (the speed change cam 32, the arm 17, and the link lever 18) is disposed outside the coating chamber R1 has been described, the speed change mechanism may be provided in the coating chamber R1. In this case, the rotating shaft side cover (the inner cover 24 and the outer cover 25) can be omitted.

  Although the fan 31c is illustrated as an example of the outside air introduction unit, the outside air introduction unit is not limited to the fan 31c. For example, a blower (such as a compressor) that can send air into the coating chamber R1 through the filter 31e can be employed as the outside air introduction unit. When a compressor is employed as the outside air introduction means, it is preferable to dehumidify the air sent by the compressor.

  The positional relationship between the first cover 22 and the second cover 23 can be reversed with respect to the holding mechanism 19 in the rotation direction about the rotation shaft 15. Moreover, although the example where the cover part 22b of the first cover 22 overlaps the outer side in the radial direction with respect to the cover part 23b of the second cover 23 has been described, the cover part 23b overlaps the cover part 22b from the outer side in the radial direction. It may be. Even in this case, it is preferable that the sandwiched member 7 is provided between the cover 22b and the cover 23b.
