Abstract

PURPOSE:To make a frame on an operational side compact, and to perform paper supply easily by one operator by making the size of a turret wheel on the operational side small, and by forming a tooth that engages with a driving transmission gear, on the entire inner circumferential surface of the wheel. CONSTITUTION:A turret wheel 43 on an operational side is formed as small as possible, while a tooth that engages with a driving transmission gear 42 is formed on the entire inner circumferential surface, so as to support a peripheral surface on a frame 36' through a bearing 45. The turret wheel on the operational side is made compact thereby, and the frame 36' is also lowered. In the time of paper supply, by one operator's standing on the operational side and his moving with a film held on the side, the film can be wound around a winding core 35b in rotation that is held between a pair of turret wheels 37 and 43 supported by the frames 36, 36' of both on the driving side and on the operational side, and can be drawn out.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a film manufacturing device, a filing machine, a paper manufacturing machine,
This invention relates to a sheet winding machine applied to textile finishing machines, etc.

(Conventional technology) FIG. 3 shows a conventional turret type winder.

In the figure, 1 is a wide film that is fed, and the film 1 is wound up to a certain length on a long winding core 5 that extends perpendicular to the plane of the paper and is rotatably supported, and then is brought to the take-out position B. ,
The next winding core 5a is rotated to the winding position A. This turning is achieved by a turret wheel 7 that is rotatably and precisely supported by a highly rigid frame 6 and has teeth formed all over its outer circumferential surface, and a gear 8 that meshes with the teeth of the turret wheel 7.
This is accomplished by being rotated by a turret motor 10 via a reducer 9 having a sufficient reduction ratio. It is desirable to use a DC motor or a pulse motor as the turret motor 10.

This rotational speed control, that is, the rotational speed control of the turret motor 10, is performed by pulse input from the control device 11, and the frequency of this pulse and the motor rotational speed, and therefore the rotational speed of the winding core, are made to correspond. ing. Further, the number of pulses corresponds to the motor rotation angle, and thus to the turning distance of the winding core.

The rotation speed of the winding core 5a is controlled by the control device 11 from the take-out position B to the winding position A at a speed as shown in FIG. That is, the winding core 5a starts turning from the take-out position B, is turned at a relatively high speed NI, and reaches a position C close to the winding position. The arrival of the winding core 5a at position C is detected by a suitable detector 12 such as a limit switch or a nearby switch, and the signal is transmitted to the control device 11, which decelerates the rotation speed to a considerably low speed N2. be done. Thereafter, the winding core 5a reaches a position closer to the winding position A than the position C. Detection that the winding core 5a has reached the position is performed by a high-precision detector 13 such as a high-precision proximity switch, and the rotational speed of the turret motor 10 is controlled by the signal from this detector 13. starts counting pulses.

(Problems to be Solved by the Invention) In the above winding machine, as shown in FIG. Even if an attempt is made to pass the film 1 that is being guided more continuously through the winder (this is called a paper threading operation).
The reality is that operator M cannot easily do this alone.

In addition, 21 in the figure is an operation panel for the winding machine. This paper passing work needs to be done quickly. Recently, production speeds have become faster (over 200 m/min), and if a sheet fails to pass, a pile of film will continue to come out from upstream, and the equipment will essentially stop. However, unless this is removed, production cannot be restarted, resulting in a huge production loss.

On the other hand, the reality is that it is not permissible to increase the number of operators in order to save labor.Furthermore, as mentioned above, the frames of conventional winding machines have become larger, which increases equipment costs and increases equipment costs. The installation space must also be increased.

The present invention has been made in order to solve the various problems mentioned above at once, and it is possible to easily perform paper threading work by one operator, as well as to save space and reduce equipment costs. The purpose is to provide a material winding machine.

(Means for Solving the Problems) In order to achieve this object, the present inventor proposed that in a conventional winding machine, the driving means of the turret wheel is provided with a bearing on the inner circumferential side of the wheel, and is used as an external gear. We focused on the fact that this requires a large, highly rigid frame because it uses an external gear type swivel bearing that is driven by meshing with a drive gear. We were convinced that this would be easy to do, and would be advantageous in terms of both economy and space.

The structure adopted here is to rotate a pair of turret wheels supported by both the driving side and operating side frames via bearings, and to move the winding core held between both turret wheels to the winding position and take it out. In a sheet winding machine equipped with a mechanism for rotating between positions, the turret wheel on the operating side is formed to have a diameter as small as possible, and teeth that mesh with a drive transmission gear are formed on the entire inner peripheral surface of the turret wheel. , is a sheet-like material winding machine characterized in that its outer circumferential surface is supported by a frame via a bearing, and this is a means for solving the above-mentioned problem.

(Function) Since the sheet winder according to the present invention is configured as described above, the turret wheel portion on the operating side is compact and has a low bulk, so that only one operator can feed the sheet. stand on the operating side and move while holding the side of the sheet in your hand, allowing you to wrap the edge of the sheet around one of the take-up cores.When this winding is finished, the end of the sheet can be wrapped around one of the take-up cores. The rotation eliminates the slack in the sheet.At this point, the automatic cutting device is activated to automatically wind and cut the sheet around another winding core at the winding position, and a regular winding operation begins.

(Example) Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIG. 1 shows a schematic structure of a sheet-like material winding machine which is a typical embodiment of the present invention, and in the same figure, 35a, 35
b is a winding core, and both ends of each winding core 35a, 35b are connected to a pair of core shafts 46a, 46b, 46c, respectively.
, 46d is held by a core boulder fixed to the tip.

Each core shaft 46a, 46b, 46c, 46d is supported by an internal bearing (not shown) of a holding part 49a, 50a, 49b, 50b, respectively.
9a, 49b.

The operation side holding parts 50a and 50b are the drive side turret wheel 37 and the operation side turret wheel 43, respectively.
are integrated with a phase difference of 180°.

External teeth are formed on the entire outer circumferential surface of the drive-side turret wheel 37 in which the respective drive-side holding parts 49a and 49b are housed on the inner circumferential side, and external teeth are formed on a part of the inner circumferential surface and a part of the drive-side frame 36. It is supported by the drive side frame 36 via an assembled bearing 44 (herein, this bearing is referred to as an externally toothed swing bearing). On the other hand, the operation side turret wheel 43 houses each operation side holding part 50a, 50b on its outer circumferential side,
Therefore, when compared to the diameter of the drive side turret wheel 43, its diameter is approximately twice as small as the diameter of the holding part. The operating side frame 3
6'.

34 and 34' are drive-side and operation-side turret wheel drive force transmission shafts, respectively; both shafts 34
．． 34' shares a driving force transmission gear 39 that meshes with the output gear 39' of the motor 40 which is the driving source.

38 is a gear attached to the drive-side turret wheel drive force transmission shaft 34, which meshes with the external teeth of the drive-side turret wheel 37, transmits the rotational force of the motor 40 to the turret wheel 37, and transmits the rotational force of the motor 40 to the drive-side turret wheel 37. 49a,
Rotate 49b. On the other hand, the operating side turret wheel driving force transmission shaft 34' is provided with 41 gears, and the turret wheel meshes with the internal teeth of the operating side turret wheel 43 via a gear train of 41', 41'', 41''. The driving force is transmitted to the driving gear 42 and the turret wheel 43 is rotated.

Reference numerals 47a and 47b are core shaft drive motors assembled to the holding parts 49a and 49b of the drive side turret wheel 37 1, a toothed pulley and a belt 41L 4
The winding cores 35a and 35b are driven and rotated via the winding cores 8a', 48b and 48b' to wind up the sheet-like material.

As is clear from the above configuration, in the sheet-like material winding device according to the present invention, the bearing 45 between the operating side frame 36' and the turret wheel 43 is an internal gear type swivel bearing, so that the frame 36' is extremely compact.

Next, the operation of the apparatus of the above embodiment will be described. Although not shown, the configuration other than the above configuration is substantially the same as the conventional device shown in FIG. 3.

Now, for example, when trying to pass a new film through the winder, since the height of the frame 36' on the operating side is low,
A human operator M stands on the operating side and moves the film while holding it sideways, and winds it around the rotating take-up core 35b. The slack of the wound film is absorbed by the rotation of the winding core 35b, and the film can be taken up steadily.

When the film is steadily taken up by the winding core 35b, an automatic cutting device (not shown) is activated to automatically cut the film and wind it around the other winding core 35a at the winding position. Winding is started and production operation is started.

Thereafter, the same operations as in the conventional device shown in FIG. 3 are repeated to continuously wind the film.

(Effects of the Invention) As described in detail above, according to the present invention, the operating side turret wheel is made small in diameter and can be driven from the inner circumferential side, so that the operating side frame can be configured compactly, which was previously impossible. Paper threading work (one-man threading) can now be performed by one operator at the take-up machine section, which was previously possible, and by making one-man threading possible, the number of personnel required for paper threading work can be reduced. Work can be streamlined. Furthermore, one-man threading eliminates the need for cooperative work between operators, making it easier to respond to higher speeds. Further, the winding machine of the present invention allows the entire machine to be made compact, and investment costs can be reduced.
