[0018] Hereinafter, one embodiment of the present invention will be described.

[0019] -composition- First, the configuration of a winding device 100 according to the present embodiment will be described with reference to Figs.

[0020] The winding device 100 is configured to divide and wind up a strip-shaped sheet 150 that is unwound from a raw roll (not shown). The winding device 100 is also configured to have a replaceable winding shaft 152 on which a winding core 151 that winds up the sheet 150 is attached. The sheet 150 may be made of paper or resin. As shown in FIG. 1, the winding device 100 includes a winding mechanism 8, a discharge mechanism 5, a product receiving table 6, and a winding shaft supply mechanism 7. In FIG. 1, the upstream side is the Y1 direction side, and the downstream side is the Y2 direction side.

[0021] [Take-up mechanism] The winding mechanism 8 is a so-called two-drum winder, and includes a slit section 1, drums 2a and 2b, a chuck 3, a press roller 4, and adjustment mechanisms 30 and 40. The slit section 1 is provided to continuously make slits in the sheet 150 along the conveying direction to divide the sheet 150 into a plurality of sheets 150a.

[0022] The two drums 2a and 2b are provided to rotate a winding shaft 152. The winding shaft 152 is disposed on the drums 2a and 2b, and is disposed between the upstream drum 2a and the downstream drum 2b. A pinch roller 9b that presses the sheet 150a against the drum 2a is provided on the upstream side of the drum 2a. The sheet 150a that has passed through the slit section 1 is transported between the drum 2a and the pinch roller 9b via a guide roller 9a.

[0023] A plurality of winding cores 151 are detachably attached to the winding shaft 152. The winding shaft 152 is configured to be actuated by supplying air to hold the plurality of winding cores 151. The winding shaft 152 can be maintained in a state in which the plurality of winding cores 151 are attached thereto by maintaining the air supplied to the winding shaft 152. The plurality of winding cores 151 are arranged along the axial direction of the winding shaft 152 so as to correspond to the divided sheets 150a. Therefore, the winding cores 151 are rotated together with the winding shaft 152, so that the divided sheets 150a are wound around the respective winding cores 151. The sheet 150a is wound around the winding cores 151 to form a winding roll 150b, and the winding roll 150b is in contact with the drums 2a and 2b.

[0024] The chuck 3 is configured to rotatably support an end of the winding shaft 152. The chuck 3 is provided on a slide member 31 of the adjustment mechanism 30 and configured to be movable in the vertical direction. Two chucks 3 are provided to support both ends of the winding shaft 152, respectively, but only one of the pair of chucks 3 is shown in FIG.

[0025] The press roller 4 is disposed above the winding roll 150b and is provided to press the winding roll 150b against the drums 2a and 2b. The press roller 4 is provided on a slide member 41 of the adjustment mechanism 40 and configured to be movable in the vertical direction.

[0026] Here, a pressing force from the press roller 4 and a pressing force from the weight of the winding roll 150b are applied to the contact points between the winding roll 150b and the drums 2a and 2b. Since the winding quality varies depending on the contact pressure between the winding roll 150b and the drums 2a and 2b, the winding device 100 is provided with adjustment mechanisms 30 and 40 for adjusting the contact pressure.

[0027] The adjustment mechanism 30 is provided to adjust the pressing force due to the weight of the winding roll 150b. The adjustment mechanism 30 includes a slide member 31, a chain 32, a fixed member 33, pulleys 34a to 34c, and an air cylinder 35. The adjustment mechanism 30 is disposed downstream of the winding roll 150b. The adjustment mechanism 30 is provided on each of a pair of side frames (not shown).

[0028] The slide member 31 is configured to be movable along a guide rail 31a provided on the side frame. The guide rail 31a is formed to extend in the vertical direction, and the slide member 31 is movable in the vertical direction. The slide member 31 is provided with a chuck 3.

[0029] One end of the chain 32 is connected to the slide member 31, and the other end is fixed to the side frame by a fixing member 33. The chain 32 is hung on pulleys 34a to 34c. The pulleys 34a and 34b are fixed pulleys, and their rotating shafts are fixed to the side frame. The pulley 34c is a movable pulley, and its rotating shaft is provided on the piston of an air cylinder 35. The air cylinder 35 is provided to move the pulley 34c in the vertical direction.

[0030] In this adjustment mechanism 30, by adjusting the force with which the air cylinder 35 lifts the slide member 31, it is possible to adjust the pressing force due to the weight of the winding roll 150b.

[0031] The adjustment mechanism 40 is provided to adjust the pressing force of the press roller 4. The adjustment mechanism 40 includes a slide member 41, a chain 42, a fixed member 43, pulleys 44a to 44c, and an air cylinder 45. The adjustment mechanism 40 is disposed upstream of the winding roll 150b. The adjustment mechanism 40 is provided on each of the pair of side frames.

[0032] The slide member 41 is configured to be movable along a guide rail 41a provided on the side frame. The guide rail 41a is formed to extend in the vertical direction, and the slide member 41 is movable in the vertical direction. The slide member 41 is configured to rotatably support the press roller 4.

[0033] One end of chain 42 is connected to slide member 41, and the other end is fixed to the side frame by fixed member 43. Chain 42 is hung on pulleys 44a to 44c. Pulleys 44a and 44b are fixed pulleys, and their rotating shafts are fixed to the side frame. Pulley 44c is a movable pulley, and its rotating shaft is provided on the piston of air cylinder 45. Air cylinder 45 is provided to move pulley 44c in the vertical direction.

[0034] In this adjustment mechanism 40, the pressing force of the press roller 4 can be adjusted by adjusting the force with which the air cylinder 45 lifts the slide member 41.

[0035] [Ejection mechanism] The discharge mechanism 5 is provided to discharge the winding roll 150b wound by the winding mechanism 8. The discharge mechanism 5 includes an arm 51, a slider 52, and a push-out roller 53. The discharge mechanism 5 is disposed upstream of the drums 2a and 2b.

[0036] The push-out roller 53 is provided to push out the winding roll 150b when the winding roll 150b is discharged. The push-out roller 53 is rotatably attached to the slider 52 and is disposed on the downstream side of the slider 52. The slider 52 is configured to be movable along a rail 52a. The arm 51 is rotatable and is connected to the slider 52. Therefore, the slider 52 is moved along the rail 52a by the rotation of the arm 51. The arm 51, the slider 52, and the rail 52a are provided as a pair on the left and right sides so as to face each other with the push-out roller 53 in between.

[0037] [Product receiving stand] The product receiving table 6 is disposed downstream of the drums 2a and 2b, and is configured to receive the winding roll 150b discharged by the discharge mechanism 5. Between the product receiving table 6 and the drum 2b, inclined surfaces 10a to 10c (see FIG. 2) are provided. In the product receiving table 6, the winding shaft 152 is pulled out from the winding roll 150b and discharged, and a new winding core (empty winding core) 151 is fitted onto the winding shaft 152. The new winding shaft 152 is then sent to the winding shaft supply mechanism 7.

[0038] [Winding shaft supply mechanism] The winding shaft supply mechanism 7 is provided to supply a new winding shaft 152 to the winding bearing position P1 (see FIG. 2) of the winding mechanism 8 after the winding roll 150b has been discharged by the discharge mechanism 5. The winding shaft supply mechanism 7 is disposed between the winding bearing position P1 of the winding mechanism 8 and the product receiving table 6. The winding bearing position P1 is an upper position between the drums 2a and 2b, and is the position where the winding mechanism 8 starts winding the sheet 150a.

[0039] As shown in Fig. 2, the winding spindle supply mechanism 7 includes a main unit 71 and guide rails 72 and 73. In the winding spindle supply mechanism 7, a new winding spindle 152 supplied from the product receiving table 6 is made to wait at a winding spindle standby position P2. The winding spindle standby position P2 is disposed downstream of the winding bearing receiving position P1, and is disposed below the inclined surfaces 10a to 10c. The guide rails 72 and 73 are examples of the "first guide rail" and the "second guide rail" of the present invention, respectively.

[0040] 3, the main unit 71 has a stay 711 extending in the width direction (X direction), and a lifting member 712 and a side bracket 713 attached to both ends in the width direction of the stay 711. Note that FIG. 3 shows one of the pair of lifting members 712 and side brackets 713.

[0041] An inclined surface 10c is attached to the upper end of the stay 711 over most of the width. The lifting member 712 is connected to a power source (not shown) and is provided so as to be movable along a guide rail 712a. The guide rail 712a is provided on the side frame and is formed to extend in the vertical direction. Therefore, the main unit 71 is configured so as to be liftable. The side bracket 713 is attached to the lower end of the stay 711 and has two plate-shaped parts extending downward. The main unit 71 is also provided with a support member 74, a winding shaft operating part 75, a stopper 76, and a position adjustment member 77.

[0042] The support member 74 is provided to support a new winding shaft 152 onto which the winding core 151 supplied from the product receiving table 6 is fitted. The support member 74 is provided on each of the pair of side brackets 713. The support member 74 is attached to the side bracket 713 via a rotating shaft 74a and is configured to be rotatable relative to the side bracket 713.

[0043] As shown in Fig. 2, the support member 74 has a mounting portion 74b on which a new winding shaft 152 is placed. The mounting portion 74b is formed to be recessed in an arc shape, and is formed to follow the outer circumferential surface of the winding shaft 152. On the upstream side of the support member 74, a lever 74c extending upward is provided, and a roller 74d is provided at the tip of the lever 74c. In addition, a return spring (not shown) is provided on the support member 74, and the biasing force of the return spring causes the support member 74 to return to its initial position (the position shown in Fig. 2).

[0044] As shown in FIG. 3, the winding shaft operating unit 75 is provided to adjust the widthwise position of the new winding shaft 152 at the winding shaft standby position P2 and to cause the new winding shaft 152 to hold a plurality of cores 151. The winding shaft operating unit 75 has an air supply unit 751 provided on one of the pair of side brackets 713 and a winding shaft bearing unit (not shown) provided on the other of the pair of side brackets 713. The air supply unit 751 and the winding shaft bearing unit are disposed to face each other in the widthwise direction and to correspond to the new winding shaft 152 placed on the placement unit 74b. The air supply unit 751 has a socket 751a that can advance and retreat in the widthwise direction. The winding shaft bearing unit is configured to be able to advance and retreat in the widthwise direction.

[0045] In the winding shaft operating section 75, the winding shaft bearing section is moved inward in the width direction, and the socket 751a is moved inward in the width direction, thereby adjusting the position of the new winding shaft 152 in the width direction, and the socket 751a is fitted into the plug 152a of the new winding shaft 152. With the socket 751a fitted into the plug 152a, air is supplied from the air supply section 751 to the new winding shaft 152, whereby the new winding shaft 152 is operated to hold the multiple winding cores 151.

[0046] The stoppers 76 are provided to restrict the rotation of the support member 74. The stoppers 76 are provided on each of the pair of side brackets 713. Specifically, the stoppers 76 have pins 76a that are movable forward and backward in the width direction, and are configured so that the pins 76a protrude inward in the width direction and engage with the support member 74, thereby fixing the support member 74 in an initial position.

[0047] The position adjustment member 77 is provided to adjust the position of the winding core 151 relative to the new winding spindle 152 placed on the placement portion 74b. The position adjustment members 77 are provided near both ends of the stay 711. The position adjustment member 77 has a claw portion 77a, and is configured so that the claw portion 77a can rotate and move in the axial direction.

[0048] 2, the guide rails 72 and 73 are provided to guide the new winding shaft 152 delivered from the support member 74 to the winding bearing position P1. The guide rails 72 and 73 are provided as a pair on the left and right sides so as to face each other in the width direction. The guide rails 72 and 73 are disposed on the outside in the width direction with respect to the drums 2a and 2b and the inclined surfaces 10a to 10c.

[0049] The guide rail 72 is disposed on the product receiving table 6 side (downstream side), and the guide rail 73 is disposed on the take-up bearing position P1 side (upstream side). The guide rail 72 is connected to a drive unit (not shown) and configured to be retractable outward in the width direction by the drive unit. The guide rail 73 is connected to a drive unit 73b via an arm 73a and configured to be retractable downward by the drive unit 73b.

[0050] -Operation- Next, the operation of the winding device 100 according to this embodiment will be described with reference to Figs. 1 to 8. The winding shaft 152 is rotatably held by the chuck 3, and a plurality of winding cores 151 are attached to the winding shaft 152. As shown in Fig. 2, the main unit 71 is retracted downward, and the inclined surface 10c is disposed so as to be continuous with the inclined surface 10b. The guide rail 72 is retracted outward in the width direction by a drive unit (not shown), and the guide rail 73 is retracted downward by a drive unit 73b. The support member 74 is fixed to an initial position by a stopper 76.

[0051] First, as shown in FIG. 1, sheet 150 is unwound from a raw roll (not shown) and sent to slit section 1. Then, as sheet 150 passes through slit section 1, continuous cuts are made in the sheet 150 along the conveying direction. Therefore, sheet 150 is divided into a plurality of sheets 150a. The divided sheets 150a are sent between drum 2a and pinch roller 9b via guide roller 9a. Then, sheet 150a is taken up by take-up roll 150b, which is rotated counterclockwise in FIG. 1.

[0052] The winding roll 150b is formed by winding the sheet 150a around a winding core 151. The multiple winding cores 151 are arranged to correspond to the divided sheets 150a, and each divided sheet 150a is wound onto each winding core 151. The winding roll 150b is driven mainly by the drums 2a and 2b.

[0053] At this time, the press roller 4 presses the winding roll 150b towards the drums 2a and 2b. The pressing force of the press roller 4 is adjusted by the adjustment mechanism 40. Furthermore, as the sheet 150a is wound up, the weight of the winding roll 150b increases. The pressing force due to the weight of the winding roll 150b is adjusted by the adjustment mechanism 30. This makes it possible to appropriately adjust the contact pressure between the winding roll 150b and the drums 2a and 2b. The press roller 4 and the winding shaft 152 are driven as appropriate.

[0054] 2, when a new winding shaft 152 fitted with multiple winding cores 151 is transferred from the product receiving table 6 to the support member 74, the new winding shaft 152 is placed on the placement portion 74b. At this time, the support member 74 is fixed to the initial position by the stopper 76, so that the support member 74 will not rotate even if an impact occurs when the new winding shaft 152 is transferred to the support member 74.

[0055] Next, the socket 751a (see FIG. 3) of the air supply unit 751 is moved inward in the width direction, and the winding shaft bearing portion (not shown) is moved inward in the width direction. As a result, the new winding shaft 152 supported by the support member 74 is sandwiched between the socket 751a and the winding shaft bearing portion, and the position of the new winding shaft 152 in the width direction is adjusted. In addition, the claw portions 77a of the pair of position adjustment members 77 are rotated to abut against the outer circumferential surface of the new winding shaft 152. Then, the pair of claw portions 77a are moved inward in the width direction, and the multiple winding cores 151 are sandwiched between the pair of claw portions 77a, and the positions of the multiple winding cores 151 relative to the new winding shaft 152 are adjusted.

[0056] Also, the socket 751a is fitted to the plug 152a (see FIG. 3) of the new winding shaft 152, and air is supplied from the air supply unit 751 to the new winding shaft 152. This causes the new winding shaft 152 to operate and hold the multiple winding cores 151. That is, while the winding mechanism 8 is winding the sheet 150a, the multiple winding cores 151 are pre-attached to the new winding shaft 152 at the winding shaft standby position P2. That is, before replacement of the winding shaft 152 is started, the multiple winding cores 151 are attached to the new winding shaft 152. Thereafter, the socket 751a is moved outward in the width direction and is released from the engagement with the plug 152a.

[0057] 4, as the winding diameter of the winding roll 150b increases, the chuck 3 is moved upward by the adjustment mechanism 30, and the press roller 4 is moved upward by the adjustment mechanism 40. Specifically, the air cylinder 35 pulls down the pulley 34c, thereby moving the slide member 31 and the chuck 3 upward, and the air cylinder 45 pulls down the pulley 44c, thereby moving the slide member 41 and the press roller 4 upward. At this time, the contact pressure between the winding roll 150b and the drums 2a and 2b is adjusted by the adjustment mechanisms 30 and 40 so as to be appropriate.

[0058] When the winding roll 150b is wound up and the winding shaft 152 is replaced, the winding of the sheet 150a is temporarily stopped. After that, the press roller 4 is moved upward so as to be separated from the winding roll 150b. In addition, the chuck 3 releases the winding shaft 152 from its hold.

[0059] Next, as shown in FIG. 5, the arm 51 of the discharge mechanism 5 is rotated, and the slider 52 is moved downstream along the rail 52a. As a result, the winding roll 150b is pushed downstream by the push roller 53, and the winding roll 150b rolls downstream on the inclined surfaces 10a to 10c. As a result, the winding roll 150b is placed on the product receiving table 6, and the sheet 150a is cut by a cutting device (not shown). The downstream cut end of the sheet 150a is wound up by rotating the winding roll 150b on the product receiving table 6. Also, the chuck 3 is moved downward and disposed at the winding bearing position P1.

[0060] 6, the guide rail 72 is advanced inward in the width direction by the drive unit, and the guide rail 73 is advanced upward by the drive unit 73b. This enables the guide rails 72 and 73 to guide the new winding shaft 152. In addition, the fixation of the support member 74 by the stopper 76 is released.

[0061] Then, as shown in FIG. 7, the main unit 71 is raised, and at that time, the roller 74d is brought into contact with the lower end of the guide rail 72. Therefore, as the main unit 71 is raised, the lever 74c is pressed, and the support member 74 is rotated about the rotation shaft 74a. As a result, the new winding shaft 152 rolls down from the placement portion 74b and is delivered to the guide rail 72. The new winding shaft 152 rolls upstream on the guide rails 72 and 73 and is supplied to the winding bearing position P1. After that, as shown in FIG. 8, the main unit 71 is lowered and retreated, and the support member 74 is returned to its initial position by a return spring (not shown). Then, the support member 74 is fixed to its initial position by the stopper 76. Also, the guide rail 72 is retreated to the outside in the width direction by the drive unit, and the guide rail 73 is retreated downward by the drive unit 73b.

[0062] Then, the new winding shaft 152 at the winding bearing position P1 is held by the chuck 3, and the upstream cut end of the sheet 150a is wound around the winding core 151 of the new winding shaft 152. Then, the press roller 4 is moved downward, and the new winding roll 150b is pressed against the drums 2a and 2b by the press roller 4, and the winding of the sheet 150a is restarted.

[0063] On the product receiving table 6, the winding shaft 152 is pulled out from the placed winding roll 150b, and the winding roll 150b is discharged. A new winding core 151 is fitted onto the winding shaft 152, and the new winding shaft 152 is sent to the winding shaft supply mechanism 7.

[0064] -effect- In this embodiment, as described above, by previously mounting a plurality of winding cores 151 on a new winding spindle 152 at the winding spindle standby position P2 before starting replacement of the winding spindle 152, it is possible to shorten the time required to replace the winding spindle 152 compared to a case in which the winding cores are mounted after replacement of the winding spindle has started, and therefore it is possible to improve productivity.

[0065] In addition, in this embodiment, by locating the winding shaft bearing position P1 near the winding shaft standby position P2, the transport path length of the new winding shaft 152 transported from the winding shaft standby position P2 to the winding shaft bearing position P1 can be shortened, which also shortens the replacement time of the winding shaft 152.

[0066] Furthermore, in this embodiment, since the lever 74c and the roller 74d are provided on the support member 74, the support member 74 is rotated by the rise of the main unit 71. This simplifies the device configuration and reduces manufacturing costs compared to the case where a dedicated power source is provided to rotate the support member.

[0067] In addition, in this embodiment, the stopper 76 is provided, so that even if an impact occurs when a new winding shaft 152 is handed over to the support member 74, the support member 74 can be prevented from moving.

[0068] In this embodiment, the drive unit retracts the guide rails 72 outward in the width direction, so that the guide rails 72 do not get in the way when the sheet 150a is wound or the winding roll 150b is discharged. When replacing the winding shaft 152, the guide rails 72 advance outward in the width direction, so that the guide rails 72 can guide the new winding shaft 152.

[0069] In this embodiment, the drive unit 73b retracts the guide rail 73 downward, so that the guide rail 73 does not get in the way when the sheet 150a is wound or the winding roll 150b is discharged. When replacing the winding shaft 152, the guide rail 73 advances upward, so that the guide rail 73 can guide the new winding shaft 152.

[0070] In this embodiment, the winding shaft operating portion 75 can adjust the position of the new winding shaft 152 in the width direction, and the position adjustment member 77 can adjust the positions of the multiple winding cores 151 in the width direction.

[0071] In addition, in this embodiment, the push-out roller 53 is provided in the discharge mechanism 5, so that the take-up roll 150b can be pushed out smoothly.

[0072] -Other embodiments- It should be noted that the embodiments disclosed herein are illustrative in all respects and are not intended to be limiting. Therefore, the technical scope of the present invention is not interpreted solely by the above-described embodiments, but is defined by the claims. The technical scope of the present invention includes all modifications within the scope and meaning equivalent to the claims.

[0073] For example, in the present embodiment, an example in which the slit portion 1 is provided has been shown, but the present invention is not limited to this, and the slit portion may not be provided.

[0074] Further, in the present embodiment, an example has been shown in which the winding mechanism 8 is a two-drum winder, but the invention is not limited to this, and any type of winding mechanism may be used. [Explanation of symbols]
