PURPOSE:To simplify structure of mounting a winding core support member to winding core spanning arms by a method wherein the winding core spanning arms are moved along rails according to the division position of a division sheet to position a pair of the winding core spanning arms on both sides and the winding core support members. CONSTITUTION:When the division position of a beltform sheet S is varied by means of a splitter K, a pair of winding core spanning arms 1 on both sides are moved along rails 6 by means of screw shafts 11 for feed on both sides and engaging mechanisms 13 for feed on both sides to position the winding core spanning arms and winding core support members 3 on both sides in the direction of the width of a beltform sheet S. After winding core C is prepared between a pair of the winding core support members 3, each of a pair of the winding core arms 1 is moved forward toward the winding core C, and the winding core C is supported in a position to wind a division beltform sheet S'. After completion of winding, each of the winding core spanning arms 1 is moved backward from the winding core C, and is released from engagement with the winding core support member 3 to take out a sheet R in roll. This constitution enables simplification of structure of mounting of the winding core support members to the winding core spanning arm.

Description

Detailed Description of the Invention (Industrial Application Field) This invention is a method of dividing a strip sheet of plastic film, paper, metal foil, etc. into multiple divided sheets of a desired width using a slitter that can change the sheet division width. divided into articles,
A sheet division winding device distributes a strip sheet to two winding positions in the longitudinal direction and winds it on a rotatably driven winding core provided for each distributed division winding via a touch roller. The present invention relates to a core support device.

(Prior Art) Conventionally, in the sheet division winding device described in "-", a core support device is provided in each winding device to removably support the core in accordance with the feeding position of each divided sheet in the width direction of the strip-shaped sheet. This core support device has a rail provided in the width direction of the strip sheet, and is supported and guided on the rail and can move in the width direction of the strip sheet. A pair of winding core erecting arms are positioned on both sides in the direction, and a pair of winding core erecting arms are positioned at opposing predetermined positions of each pair of winding core erecting arms (facing each other, with the axis parallel to the width direction of the strip sheet as the center). It was equipped with a core support that was rotatably mounted and engaged with the end of the first core to hold the core concentrically.This core support was able to slide in the direction of the center axis of the core The movable body is supported by a bearing held on a movable body extending from the arm, and the movable body is driven by a drive mechanism consisting of a fluid pressure cylinder provided on the two-volume core installation arm to move the two-volume core support to the winding core ( When the length of the winding core for winding the divided sheet changes, the pair of winding core installation arms are brought closer to both ends of the winding core to determine the position on the rail. After temporarily supporting the winding core between the winding core supports of the winding core installation arms on both sides, the second winding core support is driven forward by the forward/backward drive mechanism and engaged with the end of the winding core. The winding core was supported with the hook being passed between the arms. (Refer to Japanese Patent Publication No. 45-20644.) (Problems to be Solved by the Invention) By the way, the width of Wide strip-shaped sheets are generally used for packaging by only going through one divisional winding process.

Rather than being processed into narrow product sheets such as tapes, they are processed into product sheets with a predetermined width through a dividing and winding process using a sheet dividing winder that corresponds to the dividing width and three times. . However, as a recent trend, the division width of the band-shaped sheet has become more diverse.

In order to improve productivity, it is required to minimize the number of divisional winding processes that the wide belt-shaped sheet produced in the manufacturing process undergoes. For this reason, the minimum winding width specification of the sheet division winding device is made as small as possible, and divided sheets of a wide range of widths, from narrow width divided sheets to wide width divided sheets, can be wound with a pair of winding core installation arms. Is required.

Furthermore, in order to improve productivity, it is required to increase the length of the divided sheets wound around the core, that is, to increase the maximum winding diameter and to increase the speed of one winding. In order to comply with this request (ha.

The core support device must have sufficient mechanical strength to withstand the high speed rotation of a heavy sheet roll. but,"
In the conventional dual core support device, the first core support is rotatable with respect to the core mounting arms (two, and slidable in the width direction of the strip sheet). The structure for attaching the winding core support on the arm is complicated.Moreover, the structure that supports the second winding core support prevents the first winding core from colliding with the touch roller when it reaches the second winding start position. The thickness from the rotation center of the second winding core support to the surface of the winding core installation arm facing the touch roller is limited to a small value, so in order to have two functions of one rotation and sliding, ζ The structure of the coil 114 becomes complicated, and the mechanical strength of the structure for attaching the winding core to the five-winding core erection arm is also limited.Therefore, even if it is desired to increase the mechanical strength of the winding core support device, it is not possible. Furthermore, since the core supporter is provided with a mechanism for driving the core back and forth on the core installation arm, it is not possible to reduce the distance between adjacent core installation arms in the width direction of the strip sheet. .The winding core installation arms in one of the winding devices installed in two locations are connected to each other (the core installation arms supporting different winding cores are placed back to back), and the core installation arms in one of the winding devices are Since it is positioned in the space created by distributing the divided sheets to the winding device, if it is not possible to reduce the distance between the two winding core installation arms that are lined up back to back, the minimum winding width specification will have to be reduced. However, when the power of the prime mover is transmitted to the first core to rotate the core, the structure for attaching the core to the second core support becomes particularly complicated.

Therefore, in the conventional sheet division winding device, each pair of winding core installation arms are used to separate the two winding core arms into two winding widths each having a wide range of different winding widths. This was not possible structurally.

(Means for Solving the Problems) Therefore, the first invention divides the band-shaped sheet S into sheets 1-1 of a required width using a nullitter K, as shown in FIGS. 1 to 4.
S' is divided into a plurality of strips, distributed to multiple winding positions in the longitudinal direction of the strip sheet 1-3, and a touch roller T is applied around the winding core C, which is driven twice for each divided sheet s'.

- It is characterized by comprising a moving drive device for the winding core installation arm provided along the rail 6. Further, in the second invention, as shown in FIG. 3, the winding core support member 3 according to the first invention is composed of support shafts 3alV, 1bIl and supports 3a, 3b, and the support shafts 3alV, 1bII are comprised of support shafts 3alV, 1bII. 3a.

3b is rotatable. The third invention is characterized in that the supports 3a, 3b according to the second invention are able to slide in the axial direction of the core support member 3, as shown in FIG. In a fourth invention, as shown in FIG. 3, the core installation arms 1a and Ib in the core support device according to the first invention are moved from a standby position to an advanced position below the core support part A3. A core plate holder 18 is provided between the mutually facing core support members 3 to temporarily support the core coaxially with the core supports 3. Further, a fifth invention provides a forward and reverse rotation drive provided along the rail 6 as shown in FIG. A screw shaft 22 for left and right feeding rotationally driven by machine-〇- Ij4,
-1 A left-right feed engagement/disengagement mechanism is provided on each of the two winding core erection arms and engages and disengages the winding core erection arm 1 and the above-mentioned left-right feed screw shaft.

(Function) The screw shaft for left and right feed and the engagement mechanism for left and right feed move the individual winding core installation arms to the right or left side of the rail as necessary when changing the dividing position of the belt-like 7-t by the Nurikoo. The divided sheet obtained by changing the position of two divisions should be wound up.

On both sides in the width direction of the belt-shaped sheet on which the winding core is supported,
The individual two-winding core mounting arms and the winding core support part of the pair of winding core mounting arms are shown.

Can be positioned. Furthermore, after the winding core is prepared between the pair of winding core supporting members, the individual winding core erecting arms of the pair are moved forward toward the winding core, and the second winding core supporting member is engaged with the end of the winding core. By aligning the two winding cores in a predetermined position, the hook is passed between the pair of winding core installation arms, and when the seventh winding is completed, each of the pair of winding core installation arms is moved from the winding core. By retreating, the first core and the core supporting device can be disengaged, and the second core and the sheet roll can be released.

Since the core support member is supported by the bearing fixed to the second core installation arm, the structure for attaching the first volume core support member to the core installation arm is simplified.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. The wide strip-shaped sheet s is divided into multiple strips as divided sheets S' of a required width by the nullitter K, and distributed alternately to the front and rear winding positions in the flow direction of the strip-shaped sheet 1-3. After that, each core C' is wound up by a core supporting device, and each core C' is supported parallel to the width direction of the strip sheet S and driven to rotate, corresponding to the supply position of each divided sheet S'. This will be a sheet roll R.

As shown in FIG. 2, the winding core supporting device is provided with a pair of winding core erection arms 1, which are arranged on both sides in the width direction of the band-shaped sheet S of each winding core C. Bearings 2a and 2b are fixedly held at the tips of each pair of winding core installation arms 1 facing the touch roller T, and a third
As shown in the figure, one of the pair of core installation arms 1a supports the core support 3a with a bearing 2a, and the other core installation arm 1b supports the core support 3b with a bearing 2b. , are supported so as to be rotatable about respective axes parallel to the width direction of the strip-shaped sheet s, and with the core supports 3a and 3b facing each other. Winding core support 3a,
3b can engage with both ends of the winding core C to hold the first winding core C concentrically. According to this embodiment, a core tube such as a paper tube is used as the 1-volume core C, and 1 cylindrical or cylindrical support portions 3 a I, 3 b have a thickness that matches the inner circumference of the core tube.
I, and flanges 3a II, 3b II, and the support parts 3aI, 3a are inserted from both ends of the core tube into the hollow part thereof.
The core supports 3a and 3b are winding shafts that engage with the core tube by fitting bl. Furthermore, as shown in FIG. 3, a motor 4 for rotationally driving the first winding core C is attached to one winding core installation arm 1a.
In order to transmit the driving force to the winding core C, the winding core support 3a has two
For example, in Japanese Patent Application Laid-open No. 61-4160 (as shown in the figure, a core fixing means 3 for fixing a core C to a core support 3a)
aIII, and a transmission shaft 3alV having one end concentrically fixed to the support portion 3al.

A journal portion of this transmission shaft 3alV is supported by a bearing 2a.

The driving force of the motor 4 is transmitted to the transmission shaft 3alV of the first core support 3a through a suitable transmission mechanism 5 provided between the transmission shaft 3alV and the motor 4, and the second core support 3a is wound. It is transmitted to the core C.

It goes without saying that it is also possible to form the two-turn core supporter 3a and the transmission shaft 3alV into an integral structure. On the other winding core installation arm 1b.

In this case, since a drive mechanism for actively rotationally driving the winding core C is not provided, the first winding core support 3b is fixed by being fitted onto the outer periphery of the support shaft 11]H fixed between the first winding core installation arms b. It is rotatably supported by a bearing 2b. bearing 2a,
2b is for this example.

Commercially available ball bearings are arranged in two rows, and the transmission shaft 3alV of the second core support 3a and the inner circumference of the core support 3b are fixed and supported by the inner ring and outer ring of the ball bearing, respectively. format.

The manner in which the winding core support is attached is not limited to this embodiment; for example, it is possible to use not only a rolling bearing, a sliding bearing, or a run-al bearing, but also a combination of a radial bearing and a null bearing.

The core support device also includes a rail 6 along the core installation arm 1, as shown in FIG. This rail 6 extends long in parallel to the width direction of the belt-shaped sheet S, and can individually (movably support) the two-core construction arms 1 and guide them in the width direction of the belt-shaped sheet S. According to the above, the rail 6 has two guide surfaces 6a on its upper part, each consisting of an upper surface and a side surface forming an acute angle to the upper surface, as shown in FIG. The base part 11 of the winding core installation arm 1 is slidably fitted into the dovetail groove.The base part II of the winding core installation arm 1 is equipped with a clamping device 7.
- The base of the winding core installation arm II has been moved to the desired position.
can be fixed to the rail 6. In this embodiment, the rail 6 is fixedly supported on the support base 8 of the guide device 8, and the rail 6 is fixedly supported on the support base 8 of the guide device 8, and is extended in the width direction of the band-shaped seam 1-3. By moving on the rail 6, the winding core C approaches and moves away from the touch roller T. The guide device 8 is fixed to the base 9. Guide rails 8■ are arranged at two or more locations at predetermined intervals in the width direction of the sheet S and extend long in the longitudinal direction of the belt-shaped sheet S, and the guide rails 8■ are capable of linear movement while being guided by the guide rails 8■. It is composed of a movable body 8, which is mechanically restrained from moving in directions other than , and a support base 81, which is fixed to the movable body -1. The separation from T is performed by linear movement using the guide device 8''.

Compared to separation of the winding core due to rotational movement, the function of suppressing vibrations of the two-winding core installation arm and the winding core can be significantly improved. Even if high-speed winding is performed, a high-quality sheet roll can be obtained. The movement of the rail 6 is provided on the base 9-. This is performed by the drive device 10.

The winding core support device further includes a left and right feeding screw 11 along the rail 6. Further, a left-right feed engagement mechanism 13 is provided for each winding core construction arm 1 and engages and disengages the left-right feed screw shaft 11 and the winding core construction arm 1 . According to this embodiment, the screw shaft 11 for left and right feeding is as follows.

It has a right-handed thread and is driven to rotate in forward and reverse directions by a one-rotation drive device 15. Further, the left-right feeding screw shaft 11 is placed in a groove between the two guide surfaces 6a, 6a of the rail 6.
As shown in FIG. 3, the two parts protruding from the base 1al or 1bl of each winding core installation arm into the metal 1-1 are fixedly attached to the bearings 16 and 16, respectively, and pass through the shaft in a sliding manner. The left-right feed engagement mechanism 13 includes a female threaded body 131 provided between the bearings 1616 and screwed onto the left-right feed screw shaft 11, and a frictional engagement member at the tip pressed against the outer periphery of the female threaded body 131. A threaded body 131 that does not engage a friction engagement member (not shown) with the female threaded body 13I.

A clutch mechanism is used, which includes a fluid pressure cylinder 1311 located at the base IH of the first core installation arm and restrained from rotating together with the screw shaft 11. The internal threaded body 13I is restricted from one rotation by the fluid pressure cylinder 1311.
With respect to the rotating left-right feeding screw shaft 11, the arm 1 rotates relative to the left-right feeding screw shaft 11 and moves left-right, thereby moving the double-core construction arm 1 to the left and right together with the female threaded body 13I. This engagement mechanism 13 can bring the winding core installation arm 1 and the left and right feeder screws 11 into an engaged state by supplying pressure fluid to the fluid pressure cylinder 13■. Note that the engagement mechanism described in item 1 is not limited to this embodiment.
If necessary, a dog clutch using a well-known electromagnetic clutch split nut or the like may be employed.

In addition, as a moving drive device for the 4-volume core installation arm, a means for moving the 1-volume core installation arm, such as a rack and pinion or a near motor, is used instead of the screw shaft for left and right feeding and an engagement mechanism, and the rotation drive device for the screw shaft. It goes without saying that conventional technology can be applied in various ways in terms of design.

The core support device further supports a new core C as shown in FIG.
are engaged with the winding core supports 3a and 3b, and the first winding core installation arm 1a is installed.
, Ib (As an auxiliary means for supporting this, a two-volume core plate support device 17 is provided directly below the core support device 3 of each core installation arm 1. The core temporary support device 17 is provided.

A temporary support 18 that temporarily receives the winding core C, a temporary support support mechanism 19 that supports the temporary support 18 movably between the standby position and the advanced position, and a temporary support mechanism 19 that supports the temporary support 18 between the standby position and the advanced position. It is composed of an advance/retreat drive mechanism 20 that advances and retreats between the vehicle and the vehicle.

In this case, the temporary joint support mechanism 19 has a shaft 191 slidably inserted into a guide hole 19m provided on the winding core installation arm 1 and having a guide surface parallel to the axis of the second winding core support part 3. 1.91
Temporary holders 1 are attached to the inner tips of the -pair of winding core installation arms 1a and lb.
He has written several 8s. The standby position of the temporary holder 18 is at the flanges 3an, 3bll of the winding core support member 3, as shown by solid lines in FIG.
The temporary holder 18 is at a position retreated from the end face on the winding core C side toward the winding core installation arm 1 side, and the advanced position of the temporary holder 18 is as shown in FIG. The core support portion is located at a position further forward than the tip of the moon 3. In this case, the advancing/retracting drive mechanism 20 is a fluid pressure cylinder that is mounted on the winding core installation arm 1 and whose pinion tip end is engaged with the temporary support 18.

When the 1st roll core C is placed on the upper part of the temporary receiver 18, 2
Make sure that core C does not roll.

In addition, in order to temporarily support the axis of the winding core support part 3 and the winding core C so that they coincide or almost coincide, a U-shaped and a ■-shaped 7+' are formed in the direction of the axis of the seventh winding core support part 3. + or a projection for supporting the lower surface of the winding core at two points. Note that even if the outer diameter of the first winding core C is different, the height of the upper end of the first temporary support 18 must be adjusted so that the height of the second winding core C can be matched to the height of the winding core support part 3. It is desirable to be able to do so. Further, according to this embodiment, since the temporary holder 18 can be slid in parallel to the axis of the core support portion 3, the temporary holder 18
The height of the positioning means of the temporary support 18-1z does not change due to the movement of the temporary support 18-1z. For this reason, the winding core support part A
The core supporting member 3 of the first core C can be engaged with the core support by aligning the axis of the core C temporarily supported with A3.
The mounting becomes more reliable, and the end face of the first winding core is not damaged by the winding core support device 3.

Next, the operation of this core support device will be explained. When it is desired to change the width of the divided sheet S' to be wound by the sorting division winding device or the number of divided sheets S' to be wound at a time, the rail 2L for changing the position of two divisions, 1. : The Nutitter K movably supported by , is moved in the width direction of the band-shaped sheet S to a required dividing position. Along with this, as shown in Fig. 4, a pair of winding cores are arranged on both ends of the winding core on which the newly divided divided sea 1-S' is to be wound and on both sides of the second winding core C in the axial direction. Erection arm 1. a, lb core supports 3a, 3b
a winding core installation arm 1a that maintains a predetermined distance from the tip of the winding core arm 1a;
It is necessary to move each winding core installation arm 1a, Ib to the standby position of lb and the initial 1-1 position. Therefore, the left-right feeding screw shaft 11 is driven to rotate in forward and reverse directions by the rotary drive device 15, and the screw shafts 11 for left and right feeding are rotated in forward and reverse directions.

If the above-mentioned first position 1'' is on the right side of the current position, actuate the required horizontal feed engagement mechanism 13 for the core installation arm to move the core installation arm 1 to the left and right feed screw shaft 11. If the first 1" position of each winding core erection arm is on the left side of the current position, operate the left/right feeding engagement mechanism 14 to move the second winding core erection arm 1. By engaging with the left-right feeding screw shaft 12, the winding core installation arms 1 that need to be moved are sequentially moved to the initial target position, that is, a standby position for supporting the winding core C at a desired position. . Once the winding core construction arms 1 have been moved to the initial 1-1 positions, the operation of the left/right feeding engagement mechanism 13 during operation 5 is stopped, and the winding core construction arms 1 are removed from the left/right feeding screw shaft 11. . In this way, each winding core installation arm 1 has been moved by the distance v6 and placed at the initial target position. In addition, the strip sea 1
-Depending on the number of divisions into 3, it may not be necessary to use all the core installation arms 1, so select a position where the unused core installation arms 1 will not interfere with winding 2 and move them away. . Further, the rotation of each screw 11 may be stopped after all the winding core installation arms 1 have been moved to their respective 1'' positions.

Next, core supports 3a of a pair of core installation arms facing each other,
3L+, the axis of the winding core C is aligned with the axis of the seventh winding core support part 3, and the winding core C is temporarily held. The retention of this winding core C is 2
Although this may be done manually, since the winding core supporting device of this embodiment is equipped with a nine-turn core plate receiving device 17, the one-turn core plate receiving device 17 is used. The winding core C is held by the winding core board receiver Vj, 17 by driving the temporary holder 18 by the advancing/retracting drive mechanism 20, and moving the left and right temporary holders 18 and 18 from their respective standby positions as shown in FIG. It is sufficient to advance the winding core C to the advanced position and then place the prescribed winding core C on the temporary holder 18.181.

After preparing the winding core C between the winding core supports 3a and 3b of the pair of winding core erection arms 1a and lb, the pair of winding core erection arms 1a and Ib are rotated five times by the operation of the left and right feeding engagement mechanism 13. The winding core erecting arms 1a on both the left and right sides are engaged with the left and right feed screw shafts 11.
, lb, the left and right winding core supports 3a, 3b are moved forward toward the winding core C (oppositely, the supporting portions 3a of the winding core supports 3a, 3b are moved from both ends of the core tube, which is the second winding core C, into the hollow part thereof. 'l,
Insert 3bl. When the core tube end, which is the 9th core C, comes into contact with the end surface of the flange 3all of the core support 4A, the operation of the left and right feeding engagement mechanism 13 of each core installation arm 1a, Ib is stopped, and the left and right feeding mechanism 13 is stopped. The advancement of the core installation arms 1a, lb and core supports 3a, 3b on both sides toward the core C is stopped. Thereafter, the temporary holder 18 is moved back to the standby position by the driving force of the advance/retreat drive mechanism 20. with this.

This means that the winding core C is wound several times between the winding core installation arms 1a and Ib.

After the winding of the divided sheet S' is completed, the winding core C is moved to the winding core erecting arm 1a.

1b, the sheet roll R is supported by a suitable conveyance means, and then the pair of winding core erection arms 1a, I

In the above-described embodiment, the two-winding core installation arm 1 has a body structure in which the base part II and the arm body holding the bearing that holds the winding core support device 3 have a body structure. may have a structure that protrudes from the rail 60 so that the core C can be supported by the pair in a suspended state. However, the present invention is not limited to this, and it may be configured as shown in FIGS. 5 and 6, for example. Fifth
The core installation arm 1 shown in the figure includes a base II that slidably engages with a rail 6 that is movable in the longitudinal direction of the strip sheet S;
An arm 1■ whose lower end was fixed to the base 11 and whose upper end protruded toward the side where the touch roller T was provided was provided at the upper end of the arm 1■.

It is swingable about a support shaft 1■ parallel to the width direction of the band-shaped sheet S, and is composed of a swing arm 1■ hanging from the support shaft 1■. The second core support member 3 is supported by a bearing 2 held at the lower end of the swing arm 1. Moreover, the winding core installation arm 1 shown in FIG. It is composed of a swingable arm 1. The nine-volume core support member 3 is supported by a bearing 2 held at the free end of the swing arm 1.

FIG. 7 is a drawing for explaining another embodiment of the present invention. The core support device of this embodiment differs from the embodiments described above in the following points. That is, instead of the left-right feed screw shaft and the left-right feed engagement mechanism in the dual embodiment, a single screw shaft 22 provided along the rail 6 is screwed into this screw shaft 22, and each winding The internal thread body 23 is rotated in the normal direction while the base 1 of the core installation arm 1 can rotate once, and the band-shaped sheet S is restrained from moving in the width direction with respect to the core installation arm 1. Both ends of the screw 22 are connected to the rail 6.
Since the two-core installation arm 1 is fixed so that it does not rotate, rightward or leftward movement of the two-core installation arm 1 is performed by driving the female threaded body 23 in the forward or reverse direction with the prime mover 24, and the desired When the winding core installation arm 1 reaches the position, the driving of the female threaded body 23 by the prime mover is stopped and the second winding core installation arm 1 is moved.
This embodiment differs from the above-mentioned embodiment mainly in that the movement of the motor can be stopped. Note that in this embodiment, the prime mover 24
Although the female threaded body 23 is driven by a pulse motor via a helical gear mechanism, other known driving means and transmission means may also be used. In addition, to explain still another embodiment, the support shaft of the 7-volume core support member is attached in the axial direction of the core installation arm (one feature is that it is non-slidably attached to the support shaft). On the other hand, even if the winding core support is slidably attached, if the support shaft does not slide against the winding core installation arm, the mechanical strength of 2 is sufficient. For example, 2
Assuming that the winding core is attached and removed by moving the winding core installation arm 1, as shown in FIG. 3. The core support 3a is supported slidably in the axial direction.

Press the winding core support 3a forward with the coil spring 3, etc. When the first winding core is installed, push the winding core support 3a into the ninth winding core so that the first winding core support tool 3a supports the support shaft 3. This embodiment is also effective because it is possible to automatically stop the advance of the winding core installation arm upon detection of slight sliding.

Although this invention has been explained above using several examples,
Its embodiments are not limited to the above embodiments, and may be varied in various ways based on known techniques. For example, the 9-core installation arm is not limited to having its tip protruding upward from the rail; it may also protrude downward or in other directions, or it may protrude from the rail and support the winding core with a pair of hooks across it. As long as it is a long and thin arm, it can also be a stand.

Its shape does not matter. Moreover, the rail may be supported so as to be rotatable about an axis parallel to the width direction of the belt-shaped sheet. Also, the pair of core installation arms have the same core support 5 on each side. Bearings may be installed, or core rotation drive mechanisms may be installed on both sides, and surface drive using a touch roller is used to drive the rotation of the winding core, without the rotational drive of the two winding cores. There may be cases.

Further, other embodiments of the single-volume core support device are shown in FIGS. 9 to 11. An example in which the winding core support member 32 is applied to a fixed member that cannot be freely extended or retracted but can only rotate and cannot be moved horizontally will be explained with reference to FIGS. 9 to 11.

This embodiment shows a specific example in which the winding core support of the present invention is employed in the winding arm, which is effective for specifications such as wide-width, large-diameter winding with heavy loads.

What is shown in FIGS. 9 and 10 is a pair of winding arms facing each other, and only the main part of one of the winding arms is disclosed.

A winding core support member 32 is provided at the tip of the winding arm 30.5 It is fixed in a state protruding from the inward end surface of the winding arm 30, and 1 Only rotation is transmitted from a drive source (not shown) via a transmission mechanism. It has become.

and 1 cover/sheet roll stopper part 3 having a hole 31 that does not touch the outer periphery of this core support member 32;
3 is the shape of the winding arm attachment part (this is also provided, this is usually the case when one winding is completed and the sheet roll is attached to the winding arm 3).
When removing from 0, the pair of opposing winding arms 30 move so that the distance between them increases in the left and right directions. At this time, it functions to stop the sheet roll from following, and is provided with, for example, a fluid pressure cylinder 34 for pushing this. At this time, the first-turn core receiver 35 also moves at the same time.

Furthermore, a core support 35 is provided at the lower part of the first core support member 32 to support the core C. The upper end is a concave notch edge 36 that fits loosely into the lower part, and the winding core holder 35 (this is a core holder 35) that reciprocates horizontally.

Another drive mechanism, the binuton, shown in Figure 10.11,
It is reciprocated by the cylinder 38 (there are various design considerations for using other known reciprocating means, but the explanation is omitted), and the core C is replaced with the core holder 35. At this time, the winding arm 3 moves its end horizontally to the position 35a shown in chain lines in FIG.
A drive mechanism, in this case, a hydraulic cylinder 38.0, moves along with the movement of the winding core C and returns the cut edge 36 at one end of the first winding core receiver 35'' after chucking the winding core C. Retraction spring 39
This is a winding core receiver 35 equipped with.

Further, when the two-volume core receiver 35 is moved horizontally by the drive mechanism 38, the concave notch edge 36 at the - end of the two-volume core receiver 35 touches the core support member 35.
It should be placed in front of the protruding position.

Move the winding core support member 32 together with the winding arm to remove the winding core C.
When the fluid pressure of the drive mechanism 38 is released when both ends of 1 are reached, the winding core receiver 35 returns to its original position by the force of the return spring 39. The stopping part at the time of return is omitted in the figure.

(Effects of the Invention) According to the present invention, the structure of attaching the first winding core support member to the winding core installation arm is simplified, so that the first winding core support member (l) can be attached to one machine without increasing the space occupied by the first winding core supporting member (l). The strength of the target can be increased.Also.

By moving the winding core installation arm using the left/right feeding screw shaft and the left/right feeding engagement mechanism, the second winding core support member can be engaged with or disengaged from the winding core, so the winding core can be moved like a conventional method. Since there is no need for an advancing/retreating drive mechanism for advancing the support member from the core installation arm, the width in the width direction of the belt-like sheet of the two-winding core installation arm can be made narrower than in the past. For example, in a type of conventional primary sheet dividing winding device that unwinds the original film formed and wound up by a film forming machine and winds it into one piece, the film is wound up into divided films with the maximum winding width. The minimum winding width of the pair of winding core installation arms provided for this purpose was approximately 450 mm, and the maximum winding load was approximately 500 Kr. However, according to the present invention, the minimum winding width is 300 inches + maximum winding load. can be approximately 1.5 tons. Then, the belt-like sheet can be divided into divided sheets with a width of 300 mm, which is the same as the minimum division width specification, which can omit the secondary division winding process, or it can be divided into divided sheets with a maximum width of 2 3 m. You can now also wind it up. This shows that the first core support member has a structure in which the core support member is carved into the core installation arm so that it does not slide, which has an excellent weight resistance.
