Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a sheet division winding method in which a strip-shaped sheet of plastic film, paper, metal foil or the like is divided into a plurality of strips and wound around a winding shaft supported at both ends. In particular, the present invention relates to a sheet dividing winder equipped with a sheet roll removing device for removing a sheet roll from a winding shaft.

(Prior Art) Conventionally, in a sheet split winding machine, Japanese Patent Publication No.
As disclosed in Japanese Patent Publication No. 7, a turret disk having a double structure in which a winding shaft is horizontally cantilevered at both a sheet winding position and a sheet roll withdrawing position having substantially the same height, and this turret. A main frame having a receiving hole that supports the outer circumference of the disc so that it can be rotated only and supports the winding shafts at both positions, and the frame facing the main frame, projecting when necessary and winding at the winding position. Winding consisting of a shaft support mechanism that supports the free end of the shaft, a spherical bearing fitted to one side of the double structure of the turret disk, a bearing slidably fitted to the radial guide part on the other side, and its drive stop mechanism. With a shaft deflection mechanism, the winding shaft is supported at both ends during winding, and when the wound sheet roll is removed from the winding shaft, the winding shaft is cantilevered and the winding shaft is supported cantilevered. The frame on the opposite side of the turret frame does not hinder the removal of the sheet roll. In order to avoid this, there is a type in which the sheet roll is deflected to the sheet roll extraction position and the sheet roll is manually extracted.

As a device for removing the sheet roll from the winding shaft,
As shown in US Pat. No. 3,690,583, a roll wound around a cantilevered winding shaft is pushed by a pusher driven by a fluid pressure cylinder and moved along the winding shaft. There is a type in which it is moved to a receiving shaft, which is coaxially provided adjacent to the free end side of the winding shaft, and is taken out.

These types eliminate the work of removing the sheet roll together with the winding shaft from the sheet dividing winder, and removing the winding shaft from the sheet roll by the winding shaft pulling device installed in a place different from the sheet dividing winder. You can

(Problems to be solved by the invention) However, the former requires labor of an operator to remove the sheet roll, and even if the latter sheet roll removing device is applied to the former, the winding shaft is wound. Since it moves between the position and the sheet roll withdrawing position, it is difficult to provide a pressing tool for the sheet roll so as to be movable along the winding axis, and not only the mechanism becomes complicated, but also the sheet roll withdrawing device performs a winding preparation work and the like. Worsens the workability of. Further, the latter temporarily receives the sheet roll from the winding shaft to the receiving shaft, and therefore, in order to release the sheet roll from the receiving shaft, it is necessary to remove the received sheet roll from the receiving shaft. Therefore, a carriage that supports the lower surface of the sheet roll and is movable in the direction of removing the sheet roll is provided, and after the sheet roll is wound up, the carriage is advanced from the side of the sheet split winder to the lower side of the winding shaft. It is conceivable to support the sheet roll, push the sheet roll out from the winding shaft, and retract the carriage to the side of the sheet split winder to release the sheet roll onto the trolley. In the case of a sheet split winder that supports both ends, it is necessary to secure a large space for the carriage to enter below the winding shaft and to provide a guide mechanism for the carriage so that the winding shaft support exists below the winding shaft. Difficult for. Further, a sheet roll receiving table is provided outside the winding shaft instead of the above receiving shaft, and the sheet roll is extruded onto the receiving table from the winding shaft. If the width of the split sheet roll is too narrow, the rubbing on the upper surface of the receiving stand will scratch the lower surface of the sheet roll and the reel support will prevent the receiving stand from being installed close to the reel end. The released sheet roll drops before it reaches the receiving stand, and it is difficult to reliably transfer the sheet roll from the winding shaft to the receiving stand, and it is not possible to reduce the minimum division width specification of the sheet dividing winder. There was a problem with the point.

(Means for Solving the Problem) The outline of the present invention will be described with reference to FIGS. 1 and 2 showing an embodiment of the present invention. In the present invention, the strip sheet S is divided into a plurality of lines by a slitter K. In a sheet split winding machine that winds around a winding shaft 1 supported at both ends,
A winding shaft support 2 which is provided at one end of the winding shaft and can rotatably and cantilever supports the winding shaft, and is provided at a position separated from the other end of the winding shaft 1 in the axial direction of the winding shaft 1 by a predetermined distance. Is movable between a winding shaft engaging position that engages with the winding shaft 1 and a retreat position that allows the sheet roll wound around the winding shaft to be taken out. A movable winding shaft support 3 having a winding shaft holding portion 3a which holds the shaft and can release the winding shaft when necessary, a sheet roll R on the winding shaft 1 or an end surface of the winding core C or a sheet roll R, A pusher 9 that engages with both end faces of the winding core C and moves along the winding shaft to push the sheet roll outward from the other end of the winding shaft 1, and the outside of the movable winding shaft support 3 And is movably supported in the sheet roll extruding direction while bending below the other end of the winding shaft 1.
And a feeding mechanism 15 having a bendable movable body 19 for supporting the lower surface of the sheet roll R extruded from the sheet roll R.

(Operation) The reel support and the movable reel support reliably support both ends of the reel during winding. When the sheet roll is taken out, the winding shaft support cantileverly supports one end of the winding shaft together with the sheet roll, and the movable winding shaft support releases the other end of the winding shaft from the winding shaft holding portion.
It moves from the winding shaft engaging position to the retracted position, enabling the sheet roll to be extruded from the other end of the winding shaft. Then, the pusher moves from one end side to the other end of the winding shaft to push out each sheet roll from the winding shaft. The movable plate supports the lower surface of the sheet roll extruded from the winding shaft and moves in the extruding direction together with the sheet roll. Even if the sheet rolls are extruded from the other end of the winding shaft one after another, the movable body bends below the other end of the winding shaft and is fed from below one after another and lays in the sheet roll extruding direction. From the reel to the extrusion,
The movable body supports the lower surface of the sheet roll extruded from the other end of the winding shaft and can move together with the sheet roll. Therefore, the movable body does not have to enter the sheet winding area. Further, since the movable core support is provided at a predetermined distance from the other end of the winding shaft in the axial direction of the winding shaft, it is possible to install the movable body sufficiently close to the other end of the winding shaft.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS. The strip sheet S is divided into a plurality of strips by the slitter K, alternately distributed on both sides, and wound around the winding shafts 1 and 1 to become the respective sheet rolls R. FIG. 2 shows a state in which the sheet roll R and the winding shaft 1 reach the take-out position of the sheet roll R, respectively. The two-dot chain line in FIG. 2 shows the winding shaft and winding core at the winding start position. Since the winding shaft 1 winds a plurality of divided sheets S'at the same time, it may be a winding shaft capable of giving proper tension to each sheet as shown in Japanese Utility Model Laid-Open No. 61-5845. desirable. A winding shaft support 2 is provided at one end of the winding shaft 1, and the winding shaft is rotatably supported on an upper portion of the winding shaft support 2. The reel support 2 can support the reel 1 together with the sheet roll R in a cantilever manner. In this example,
The other end of the winding shaft 1 is composed of a small-diameter journal portion 1a protruding from the end portion of the winding shaft main body portion in the sheet winding region, and a bearing 1b attached to the journal portion 1a. Bearing 1b
Has a small diameter portion 1c on the winding body side and a large diameter portion 1d having the same outer diameter as the winding body on the outside thereof. At the other end of the winding shaft 1, that is, at a position a predetermined distance from the end surface of the large diameter portion 1d of the bearing 1b in the axial direction of the winding shaft, the movable winding shaft support 3
Is provided. On the upper part of the movable winding shaft support body 3, there is provided a winding shaft holding portion 3a capable of engaging with the winding shaft 1 to hold the winding shaft and release the winding shaft when necessary. The winding shaft holding portion 3a is a rod for clamping the small diameter portion 1c of the bearing 1b which receives the small diameter portion 1c of the bearing 1b constituting the other end portion of the winding shaft 1 in this case and the U shaped groove 3b. And a clamp mechanism with a fluid pressure cylinder
It consists of 3c. The sheet dividing winder of this embodiment is
Since the winding shaft 1 is of a type that separates from the touch rollers T, T supported at a fixed position according to the winding weight of the sheet roll R, the winding shaft support 1 and the movable winding shaft support 3 are provided below them. It can swing around a support shaft 4 which is parallel to the winding shaft 1.
The support shaft 4 is rotatably supported by the left and right machine frames F, F, and the winding shaft support 2 is fixed to one end thereof. A movable winding shaft support 3 is rotatably supported at the other end of the support shaft 4 with respect to the support shaft 4, and an auxiliary arm 5 is adjacent to the movable winding support 3 and supports the winding shaft. It is fixed parallel to the body 2. Then, with the fluid pressure cylinder 6a attached to the auxiliary arm 5, the knock pin 6 provided at the tip thereof is moved to the movable reel support 3
The movable winding shaft support 3 is fixed to the support shaft 4 by being pushed into the knock hole. At this time, the movable reel support 3 is in the reel engagement position, and the U-shaped groove of the reel holder 3a is
The small-diameter portion 1c of the bearing 1b is put into 3b and is in a state of being engaged with the winding shaft 1. The oscillating drive of the winding shaft support 2 is performed by the fluid pressure cylinder 7, and the oscillating drive of the movable winding support body 3 is performed by the fluid pressure cylinder 8.

At the sheet roll take-out position, the core C end surface on the winding shaft 1 supported at this position or the sheet roll R end surface or both end surfaces are engaged, and the sheet roll R is moved by moving along the winding shaft 1. A pusher 9 for pushing outward from the other end of the winding shaft 1 is provided. In this embodiment, the pusher 9 is C-shaped as shown in FIG. 2, and its opening is directed inward,
The winding shaft 1 can be received from the winding position to the sheet roll removing position, and the area of engagement with the winding core C at the time of extrusion is increased. The pusher 9 is guided by a guide frame 10 provided parallel to the winding shaft 1 and is supported by a movable support body 11. The pusher 9 is attached to both end portions of the guide frame 10 as shown in FIG. Reciprocating drive mechanism of the type in which the left and right ends of the chain 14 looped on the chain wheels 12 and 13 are locked to the support body 11, and the chain wheel 13 is driven in forward and reverse directions by a drive device (not shown). Thus, the support 11 is reciprocally driven between the standby position near the winding shaft support 2 and the sheet roll extruding position at the other end of the winding shaft 1.

On the outer side of the movable winding shaft support 3, a sheet feeding mechanism 15 is provided for mounting the sheet roll R extruded from the winding shaft 1 and feeding it in the sheet roll extruding direction. In this case, the feed mechanism 15 is a belt conveyor, and as shown in FIG. 1, a guide roller 17 supported by a frame 16 below the other end of the winding shaft, and this guide roller 17.
A bendable endless belt 19 is stretched between a guide roller 18 supported by a frame 16 at a predetermined distance in parallel with the belt 17. The guide roller 17 is rotationally driven by a drive mechanism (not shown) at the same speed as or substantially the same speed as the pushing speed of the pressing tool 9, and the belt 19 circulates and moves in the direction of the winding shaft 1 below the guide roller 17. The other end of the winding shaft 1 is bent along the guide roller to reach the upper side thereof and can be moved in the sheet roll pushing direction. Therefore, the endless belt 19 is a movable body that supports the lower surface of the extruded sheet roll R above the guide rollers 17 and 18. Although not shown, the guide roller
The lower parts of the upper parts of 17, 18 are supported by rollers or guide plates so that they are not bent by the weight of the sheet roll and hinder the feeding of the sheet roll. Then, in order to match the upper surface of the movable body 19 (belt) with the lower surface of the sheet roll R according to the winding diameter of the sheet roll R so that the sheet roll R can be extruded,
The frame 16 of the feeding mechanism 15 is supported on the elevating mechanism 20, and the feeding mechanism is
The height of 15 can be adjusted. To adjust the height of the feed mechanism 15, a photoelectric switch for detecting the end face of the sheet roll R is provided on the side surface of the feed mechanism 15 on the winding shaft 1 side, and when the end face of the sheet roll is detected, the lifting drive of the lifting mechanism is stopped. Then, the sheet roll R is moved to the end of the winding shaft 1 by the pusher 9 and temporarily stopped, and the lifting mechanism is moved.
It may be automatically performed by raising 20 to detect the end surface of the sheet roll R or the like.

Next, the operation of this device will be described. When each core C is fitted into a predetermined position from the free end of the cantilevered support shaft 1 at the sheet roll take-out position, the fluid pressure cylinder 8 drives the movable winding shaft support 3 to set it at the winding shaft engaging position. The winding shaft 1 is held by the winding shaft holding portion 3c, and the knock pin 6 is driven by the fluid pressure cylinder 6a to be pushed into the knock hole of the movable winding shaft support 3 to move the movable winding shaft support 3 and the winding shaft support 2 to each other. Thus, the winding shaft 1 is supported at both ends. And reel support 2
And the movable winding shaft support 3 are respectively connected to the fluid pressure cylinders 7, 8
Are simultaneously driven to bring the winding shaft 1 to the winding start position, and the leading end of each sheet is stopped at the winding core C to start winding. When the winding is completed, the winding shaft support 2 and the movable winding shaft support 3 are simultaneously driven by the respective fluid pressure cylinders 7 and 8 to set the winding shaft 1 at the sheet roll take-out position. The sheet roll R is now in a position where it can be engaged with the pusher 9 in the standby position. Then, the knock pin 6 is attached to the movable reel support 3
3 by driving the fluid pressure cylinder 6a and driving the clamp mechanism 3c to release the winding shaft 1 from the winding shaft holding portion 3a, and then driving the fluid pressure cylinder 8 to move the movable winding shaft support body 3. As shown in FIG. 5, the sheet roll R is swung to the retracted position so that the sheet roll R can be taken out, and the winding shaft 1 is placed in a cantilevered support state. When the winding diameter of the sheet roll R changes, the height of the belt (movable body) 19 of the feeding mechanism 15 is adjusted to the height of the lower surface of the sheet roll R by operating the elevating mechanism 20. Then, the pusher 9 is driven to move from the standby position to the sheet roll extruding position, and the sheet roll R is extruded from the other end of the winding shaft 1 which is the free end. After that, the pusher 9 is returned to the standby position. On the other hand, the belt 19 of the feeding mechanism 15 is driven during the sheet roll extrusion. Even if the sheet roll R extruded from the winding shaft 1 is a sheet roll having the smallest width, the large diameter portion of the bearing 1b is used to ensure that the sheet roll R can be placed on the belt 19 of the feeding mechanism 15. The sheet roll R can be guided to the end of the winding shaft, the movable winding shaft support 3 is inserted from the other end of the winding shaft 1 in the axial direction of the winding shaft 1 by a predetermined distance, and the feeding mechanism 15 is rotated. Since it is sufficiently close to the other end of No. 1, the extruded sheet roll R does not drop, the end surface of the sheet roll R and the peripheral edge of the sheet are not damaged, and the peripheral surface of the sheet roll R is fed without being damaged. Received on mechanism 15. And, one after another, reel 1
The belt 19 also circulates with respect to the sheet roll R extruded from the sheet roll R so as to support the lower surface of the sheet roll R one after another and move in the sheet roll extruding direction. When the sheet roll extrusion is completed,
The driving of the belt 19 is also stopped. In this way, after all the sheet rolls R have been released onto the feeding mechanism 15, the winding core C for the next winding is fitted onto the winding shaft 1 again and the winding is started in the same manner as described above.

FIG. 4 shows an embodiment of a winding shaft holding portion which is different from the above. The winding shaft holding portion 3a extends outward from the main body of the movable winding shaft support 3 in the winding shaft axial direction. It is composed of a projecting end portion 3d of the movable winding shaft support and an engaging mechanism 3e that can engage with and disengage from the other end of the winding shaft 1. In this case, the engagement mechanism 3e
Is a push cup (center cone) 3f that holds the roll shaft 1 by entering a hole provided on the end face of the roll shaft 1, a shaft 3g that rotatably supports the push cup, and a shaft that moves the shaft forward and backward. It is provided with a fluid pressure cylinder 3h.

FIG. 5 and FIG. 6 show an embodiment of a pressing tool different from the pressing tool of the above-mentioned embodiment. The pressing tool 9 is provided with a roller 9a for supporting the lower surface of the winding shaft 1. ing. Therefore, even if the length of the winding shaft 1 is long, the height of the free end of the winding shaft when the sheet roll is extruded can be maintained at a predetermined height by the roller 9a that moves smoothly together with the pressing tool 9. There may be a case where the pressing shaft 9 is directly slidably engaged with the lower surface of the winding shaft 1 to support the winding shaft 1 without using a roller.

Although the present invention has been described above centering on one embodiment, it goes without saying that the embodiment is appropriately changed depending on the implementation conditions and the like.

For example, a sheet dividing winder is a type that winds a sheet that is divided on a winding shaft that is supported at a fixed position, a type that has only one winding shaft, or a sheet that is divided into two winding shafts arranged above and below. It may be in a form of winding up. The movement of the movable winding shaft support between the winding shaft engaging position and the retracted position may be performed not by swinging about the support shaft but by swinging. Further, the drive of the movable winding shaft support is not limited to the fluid pressure cylinder, and other driving mechanism may be adopted. In the type in which the winding shaft separates from the touch roller during winding, as in the above-described embodiment. Instead of using one fluid pressure cylinder for both the drive during winding and the drive during sheet roll extraction, a dedicated drive mechanism may be provided for each. Further, there may be a case where a swing support shaft for moving between the winding shaft engagement position and the retracted position of the movable winding shaft support and a swing support shaft during winding are separately provided. The pusher may not be C-shaped, but may be simply an arm, and the mechanism for supporting the pusher so that it can move along the winding shaft and the mechanism for driving the pusher are not limited to those in the above-described embodiments, and are well-known techniques. Can be used. The movable body of the feeding mechanism is not limited to one having flexibility such as a belt, but may be one in which links and links are bendably connected by a pin or the like, and is not endlessly supported. It has a front end that bends downward in the winding axis and lies in the sheet roll extruding direction, and a rear end that is stored below it. When the sheet roll is extruded, it is pulled out and moved in the sheet roll extruding direction. The movable body may be returned in the direction opposite to the sheet roll extrusion direction. In addition, the feeding mechanism is not provided with a drive mechanism for the movable body, and the movable body is supported so as to be freely movable in the sheet roll extruding direction, and the lower surface of the sheet roll is attached to the sheet roll extruded by the pressing tool. It is also possible that the supported movable body is driven.

(Effect of the Invention) According to the present invention, when the sheet roll is removed, the winding shaft is cantilevered at one end thereof, and the sheet roll is extruded by the pusher onto the movable body provided on the free end side of the winding shaft. Since the sheet roll is once delivered from the winding shaft to the receiving shaft coaxially provided adjacent to the free end side of the winding shaft as in the conventional case, it is possible to remove the sheet roll from the receiving shaft. The sheet roll removal work is simplified compared to the required sheet roll removal. Since the winding shaft is supported at both ends during winding, the present invention is applicable not only to a winding shaft having a short length. Since the movable body is bendable and can move in the sheet roll extruding direction by supporting the lower surface of the sheet roll that is extruded one after another without entering the winding area, scratches are generated on the surface of the extruded sheet roll. There is no need to worry about making the sheet roll defective, and it occupies a small area, and the space for the truck in the take-up area is the same as when the truck is moved into the sheet roll take-up area and the sheet roll is carried out. There is no need to provide a guide mechanism for it. Moreover, since the movable body can be installed sufficiently close to the free end of the cantilever-supported winding shaft, even a narrow sheet roll can be reliably delivered onto the movable body, and the sheet roll can be securely transferred. Not hurt. Therefore, without significantly changing the winding mechanism of the conventional sheet split winding machine,
It is possible to apply the feeding mechanism and the like of the present invention, and even if it is a sheet split winder for wide belt-shaped sheets with a small minimum sheet split width specification, it is possible to cause a defect in the sheet roll when the sheet roll is removed. Without, the sheet roll can be easily removed.
