Abstract

PURPOSE:To lead the leading ends of split band-like sheets, being surely clamped, to a spool on a wind-up device by driving a movable member having an inclined surface having an inclined angle less than a frictional angle, and by providing a holding means for opening and closing first and second beam members on the inclined surface. CONSTITUTION:The leading ends of a plurality of split band-like sheets obtained by dividing a wide band-like sheet with the use of a slitter, are distributed by a distributing mechanism and are then received between first and second beam members 16, 17 of a holding device 12 which are waiting at a receiving position, and are clamped therebetween by operating a fluid pressure cylinder 27 so as to move a rod-like movable member 18 having an inclined surface 18a having an inclined angle less than a frictional angle. The holding means 12 is led to a take-out position along a split band-like sheet path, and then the leading ends of the split band-like sheets are adhered to a spool. Thereafter, a fluid pressure cylinder 28 is operated to open the first and second beam members 16, 17. Thus, it is possible to surely hold the leading ends of the split band-like sheets in a batch, thereby it is possible to prevent the split band-like sheets from being disturbed and coming off during transfer thereof.

Description

Detailed Description of the Invention (Industrial Field of Application) This invention aims to move the leading ends of a plurality of split strip sheets, which are divided and sent out from a raw strip sheet of metal foil, plastic film, paper, etc. by a slinter, to a receiving position. The present invention relates to a divided belt-shaped sheet guiding device that holds and guides the divided sheet from the sheet to the take-out position.

(Prior art) Conventionally, this type of split strip sheet guiding device has a pair of beam members closed by the action of a spring, the leading end of the split strip sheet inserted between them being held between them, and a cam mechanism that connects the split strip sheet to the spring. There was a method in which a pair of beam members were opened and released against the pressure (for example, see the specification and drawings attached to Patent Application No. 154256 of 1989).

(Problem to be Solved by the Invention) However, in the above method, the leading ends of the plurality of divided strip sheets that are sent out are pinched together and the divided strip sheets are translated, but it is difficult to ensure that the divided strip sheets are It wasn't enough to hold.

No matter what kind of split sheet it is, there will be some thickness unevenness, and there are limits to the flatness of the fc beam members in terms of processing accuracy.
Since the thickness is originally small, there may be a slight difference in thickness fc
This is a slight gap between the supporting beams and does not have a large effect on the holding force of the six-part strip sheet. Therefore, in order to securely hold the leading edge of the split strip sheet, it is necessary to apply a large amount of clamping force between the pair of beam members in order to prevent the sheet from slipping. Spring·
It is difficult to increase the force of the spring because a force must be applied from the cam to overcome the force of the spring. During the transport, a part of the divided strip sheet sandwiched between a pair of beam members may become sagging, which may interfere with the subsequent processing of the storage area, or part or all of the divided strip sheet may become slack. There was a problem in that the guide was detached from the beam member and could no longer be guided.

Note that in order to increase the clamping force, it is conceivable to attach a drive mechanism such as a fluid pressure cylinder to the beam member. However, this method requires that the structure of the holding device including the beam member of the split strip sheet becomes too large to be applied to the split strip sheet passage, and that a kth supply means for supplying fluid pressure or other power medium to the drive mechanism is required. If it becomes too complicated, there will be problems.

The object of the present invention is to obtain a simple split strip sheet guiding device that can reliably hold the split strip sheet i.

(Means to solve the problem) Achieve the above objectives! In particular, the present invention is designed to divide a wide belt-like sheet into parts using a slinter and send it out.
c. In a split strip sheet guiding device that holds and guides the leading edge of a 7% number of split strip sheets from a receiving position to a taking position, a first beam member and a second beam member sandwich the leading ends of the split strip sheets as a pair. The beam member and the first beam member are provided movably from a standby position to an operating position on the side opposite to the side where the split strip sheet front end portions are clamped, and are moved to the operating position through an inclined surface whose inclination angle is less than or equal to the friction angle. a holding device for a leading end of a divided band-shaped sheet, comprising a movable body that indirectly or directly presses the second beam member against the first beam member on the inclined surface when moved; and a holding device for supporting both ends of the holding device and dividing the sheet. a transfer mechanism attached to the receiving position, the taking-out position, and a release position after the taking-out position along the belt-like sheet path; and a clamp installed near the receiving position to drive the movable body from the standby position to the operating position. The present invention is characterized by comprising a drive mechanism and a return drive mechanism that is installed near the release position and drives the movable body from the accompaniment position to the standby position.

(Function) After the leading end of the split strip sheet is received between the first beam member and the second beam member at the receiving position, when the movable body is driven from the standby position to the operating position by the clamping drive mechanism, the movable body The second beam member is pressed against the first beam member on the inclined surface, and the leading end portions of the divided band-like sheets are clamped. Since the angle of inclination of the inclined surface of the movable body is less than the friction angle, the driving force of the clamping drive mechanism is cut off, and the movable body 6 maintains the state in which the second beam member is pressed against the first beam member on the inclined surface. . The clamping state continues until the return drive mechanism drives the movable body to the standby position.

(Example) Next, embodiments will be described with reference to the drawings.

The beam member 17 remains open in the released position II+. As shown by the chain line in FIG.
After the belt-shaped sheet SO is sent straight downward by the 3p delivery roller 2 until it comes down between a and 5a, the distributed portion is sent to the plate 5.
A and 5a are operated as indicated by the arrows to separate the leading ends of the split strip sheets S. This state is shown by the solid line in FIG. Then, when the divided strip sheet S is sent out again, its leading end is received between the first beam member 16 and the second beam member 17. The divided belt-shaped sheet S in FIG. 5 is in a stopped state with the leading end of the divided belt-shaped sheet S slightly protruding from the downstream side of the holding device 12.

Next, the fluid pressure cylinder device 28 is activated to hold the holding device 1.
The second movable body 18 is moved to the operating position, the first beam member 16 and the second beam member 17 are closed, and the leading end of the divided band-shaped sheet S is held between them.

The motor 24 is then actuated to circulate the body 22 and guide the holding device 12 to the removal position 11. During this time,
The feed roller 26 is driven. After the holding device 12 is placed at the take-out position II (and the cutting and gluing device 29 provided on the swinging arm 10 is activated to bond the divided strip-shaped sheets S to the winding core C, unnecessary portions on the tip side from the bonded portion are Cut the pieces.

When the unnecessary portion of the divided strip sheet S is cut, the motor 24 is activated again, and the transport mechanism 13 moves the holding device 12 to the release position I11. Thereafter, the fluid pressure cylinder device 27 is activated to move the movable body 18 from the operating position to the standby position, open the first beam member 16 and the second beam member 17, and remove the unnecessary portion of the divided strip sheet $ that was being held. release. This completes the winding preparation, and the holding device 12 stands by at the release position iIll.

According to this embodiment, since the divided strip sheets are alternately distributed and automatically taken to the left and right winding positions, the winding preparation work can be performed accurately and reliably in a short time.

FIGS. 8 to 10 are drawings showing a second embodiment of the present invention.

In this embodiment, as shown in FIG.
The beam member 17 is supported by the transfer mechanism 13;
As shown in FIG. 9, the movable body 18 has an inclined surface 18a that is inclined in a direction perpendicular to its longitudinal direction, and a beam member 30 is provided on the inclined surface 18a of the movable body 18.
The upper end and the lower end are respectively connected to a beam member 30 and a second beam member 17.
This shaft 31 connects the second beam member ■7 and the beam member 30.
The first beam member 16 and the movable body 18 are connected to the shaft 3.
In addition, as shown in FIG. 10, a pair of motors 32a is provided in place of the hydraulic cylinder device by means of a clamping drive mechanism.

32a and a lever 32b 32b that is rotationally driven by this motor 32a, and furthermore, a pair of motors 3 is used instead of a hydraulic cylinder device as a return drive mechanism.
This embodiment differs from the first embodiment in that levers 3a, 33a and levers 33b, 33b which are swing-driven by the motor 33a are used. According to this embodiment, as shown in FIG. 10, both ends of the movable body 18 are operated from the retracted position shown by chain lines at the receiving position I, and the movable body 18 is moved to the ninth As shown in the figure, move from the standby position shown by the chain line to the operating position shown by the solid line, and
8a pushes up the inclined surface 19a of the beam member 30, but in this case, since the second beam member 17 is supported by the transfer mechanism 13, the first beam member 16 is lowered and pressed against the second beam member 17.

In addition, in the release position III, both ends of the movable body 18 are shown by chain lines in FIG. 10, and the lever 33b is operated to the fc position;
33b, the movable body 18 moves to the standby position, the first beam member 16 is pushed up by the action of the spring 21 as shown in FIG. 8, and the first beam member 16 and the second beam member 17 are opened.

In this invention, the first beam member can be pressed against the second beam member instead of pressing the second beam member against the first beam member. In this case, even if the first beam member is pressed and sometimes moves, the second beam member is pressed against the first beam member. Therefore, when the movable body moves to the operating position, it can be considered that the second beam member is pressed against the first beam member, regardless of whether the first beam member or the second beam member moves. Further, the direction of inclination of the inclined surface of the movable body is not limited to the longitudinal direction. Furthermore, a drive mechanism other than the fluid pressure cylinder device may be employed as the clamping drive mechanism and the return drive mechanism.

FIGS. 11 and 12 are drawings showing a third embodiment of the present invention.

In this embodiment, as shown in FIG.
7 is pivotally supported by a bin 34 at one side edge of the first beam member 16, and swings to form a first beam member 16 corresponding to the clamping surface and C of the split strip sheet S on the other side edge. The movable body 18 can be opened and closed with the clamping surface of the beam member 16, and the movable body 18 is a frame that is elongated in the longitudinal direction of the first beam member 16 and the second beam member 17. is the first
This embodiment is different from the second embodiment. The first example of this example
The upper surface of the beam member 16 and the lower surface of the second beam member 17 are not parallel to each other as shown in FIG. 11, and in this case, the distance increases toward the clamping surface. The movable body 18 is movable from a standby position shown by a chain line in FIG. 11 to an operating position shown by a solid line. The tip of the inner surface corresponding to the lower surface of the second beam member 17 is an inclined surface 18a. As shown in FIG. 12, at the receiving position I, the movable body 18 is operated from the retracted position shown by the chain line. 2
The beam member 17 has a clamping surface closed so that the divided strip-shaped sheet S can be clamped. Also, at release position III,
The movable body 18 is driven by the levers 33b, 33b which are activated to the position shown by the chain line, and is placed in the standby position (and the first beam member 16 and the second beam member 17 are moved with their distal ends as shown by the chain line in FIG. 11). In this case, the inclined surface 18a of the movable body 18 directly pushes the second beam member 17.

Although the present invention has been described above with reference to a small number of embodiments, it is possible to apply it in a variety of ways depending on the implementation conditions and using the well-known techniques of machine designers.

For example, the present invention may be applied to a slitter-rewinder that winds divided strip sheets without sorting them, or other strip sheet processing devices equipped with a slitter. However, the transfer mechanism may be supported on a fixed frame.

The holding device may include a beam member supported by a transfer mechanism in addition to the first beam member and the second beam member, and the first beam member and the second beam member may be provided on the beam member. The inclined surface of the movable body is not limited to a flat surface and may be a curved surface. In addition, the movable body may not only be one that slides linearly, but also a rotary cam mechanism or the like that can be moved between a standby position and an operating position through rotational movement. In addition, it is also possible to use a clamping member having a large coefficient of friction, in which the split strip-shaped sheet clamping surfaces of the first beam member and the second beam member have an interlocking shape of concave and convex portions in order to ensure the holding. In addition to simply holding the sheet by holding it between the holding surfaces, it is also possible to hold the sheet by protruding a claw-like member into the sheet received between the holding surfaces.

The transfer mechanism is not limited to one that circulates the body; it can slide along rails, guide grooves, etc. if it can support the holding device along the divided strip sheet path and attach it to the receiving position, take-out position, and release position. A block, a swinging arm, etc. can be adopted.

Further, the clamping drive mechanism and the return drive mechanism may be of a type that rotates around a central axis parallel to the width direction of the belt-shaped sheet to drive the movable body.

(Effect of the invention) According to invention C, since the movable body is driven from the standby position to the operating position by the clamp drive mechanism and the second beam member is pressed against the first beam member by the inclined surface of the movable body, the clamp drive mechanism The driving force increases on the inclined surface of the movable body, and a large pressing force can be obtained. Therefore, it is possible to securely clamp the leading ends of each of the divided strip sheets at once with a large clamping force, and it is possible to prevent the inconvenience of the divided strip sheets from loosening or coming off during transportation.

Furthermore, even if the driving force of the clamping drive mechanism is cut off, the movable body maintains the state in which the second beam member is pressed against the first beam member by its inclined surface, so that the drive source for clamping is connected to the holding device. The structure of the holding means including the pair of beams for sandwiching the divided strip sheets can be simplified and downsized.

Therefore, it can be applied to winding preparation work where the space along the divided strip sheet path is complicated and limited to a small size, such as guiding and attaching the divided strip sheet to the winding core of the winding device. In the work of accurately preparing each divided strip sheet guided to the core of the take-out device, etc., the sheet guided to the take-out position can be processed in the next process accurately, reliably, and in a short time. become.
