DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a device for supporting a material roll. More specifically, the present invention relates to a roll material support device used for winding and unwinding material such as paper, film, and sheet.

[0002]

2. Description of the Related Art Conventionally, a roll supporting device of this type is provided with a bearing provided on the upper surface of a machine base and a supporting shaft for setting the roll. Both ends of the support shaft inserted through the hole are supported by the bearing. Also, without using such a support shaft, a rotation shaft having a tapered tip is provided on the upper surface of the machine so as to be able to rotate and move back and forth so as to oppose the roll material, and the roll material center is provided. There is also a type in which a tapered tip is pressed against both edges of the communication hole to hold the roll material. Such a device for supporting a material roll is used in conjunction with a processing device, a printing device, and other devices, and is used for automatically feeding and winding the material roll to another device. The roll material is rotated by attaching a gear motor to the end of the support shaft or the rotation shaft via a coupling. Although the form in which the roll is supported by the device is slightly different as described above, the work of attaching the roll to the device is performed by supporting the support shaft on a bearing or by positioning the roll in the position where the rotating shaft is provided. This is performed by advancing the rotating shaft while holding the rotating shaft.

[0003]

However, whether the support shaft is supported by the bearing or the web is held at the position where the rotary shaft is provided, the support shaft or the web is positioned at a predetermined position. It is necessary. In this positioning, the heavier the material roll, the more attention and labor are required, and the mounting operation requires a considerable amount of time.
This is one factor that reduces the workability and productivity of a product as a whole device including other devices linked to the support device. Therefore, the present invention provides a roll material
An object of the present invention is to provide a roll material supporting device that can be easily and quickly set.

[0004]

The technical means taken to achieve the above object is to support a material roll on the upper surface of the machine base.
Support shaft with tapered recess on both sides
Provide a pair of slopes inside and before rotating on the slope
Provide a stopper for positioning the support shaft, and
On both sides of the extension of the axis of the support shaft
To the machine section above the stopper near the side view.
The shaft center is slightly higher than the shaft center of the support shaft
And supports the rotating shaft for levitation so that it can move back and forth in the support axis direction.
The lifting shaft engages with the recess of the supporting shaft at the tip of the rotating shaft.
It is characterized by forming a beveled surface .

According to the above technical means, when the support shaft on which the material roll is supported is mounted on the slope, the support shaft rotates on the slope and stops in a state of being positioned by contacting the stopper portion . Then, the rotating shaft, whose axis is slightly higher than the axis of the supporting shaft, just above the stopped supporting shaft, moves forward, and the lifting surface formed at the tip of the rotating shaft and the both sides of the supporting shaft. The formed tapered recess engages. By this engagement, the support shaft is supported by the rotary shaft at a distance from the slope by a distance between the axis of the rotary shaft and the slope (claim 1).

[0006] The support shaft is provided with a retractable mechanism for radially extending and retracting the claws from the outer peripheral surface, and an input portion for communicating with the retractable mechanism and retracting the claws is provided in the recess. An output portion that engages with the input portion of the support shaft is provided on the distal end surface of the support shaft. It is characterized in that a driving means for applying is provided.

[0007] According to the above technical means, the support shaft is inserted into the roll material, and is mounted on the slope in a loosely fitted state. When the support shaft rotates on the slope and stops while being positioned in contact with the stopper portion , the rotating shaft associated with the driving means moves forward, and the raised surface formed at the tip of the rotating shaft and the stopped support are stopped. The tapered recesses formed on both side surfaces of the shaft engage, and the output unit and the input unit engage. By this engagement, the support shaft is separated from the slope and supported by the rotating shaft. Then, the driving force of the driving means is transmitted to the retracting mechanism provided in the support shaft via the output unit and the input unit, and the claws are projected radially from the outer peripheral surface of the support shaft to pass through the center hole of the raw material roll. Stretch to support the roll. After that, the rotating shaft is rotated to unwind and wind the web. Here, as the retracting mechanism, a member in the shape of a truncated cone or a truncated pyramid is screwed into a screw rod supported rotatably in the longitudinal direction of the shaft, and the member moves in the longitudinal direction of the shaft by rotation of the screw rod. A mechanical type in which a claw provided slidably in contact with the member at a predetermined position is protruded and retracted, a pneumatic type in which a claw is protruded and retracted by using an inflatable body such as a rubber tube, and the like, and the driving force for driving these are In the former case, the rotation is to rotate the screw bar, and in the latter case, it is the compressed air (claim 2).

[0008] Further, the support shaft is provided with a recessed guide portion guided by a slope on the circumferential surface near both ends, and a scale capable of confirming the relative position between the raw material roll and the support shaft is provided. The pair of slopes is connected by an interval adjusting mechanism for adjusting an interval between the two slopes.

According to the above technical means, the support shaft is inserted into the roll material to a predetermined position and set by using the scale as a guide. When the guide portion which is recessed in the support shaft is placed on the slope to engage a slope, rotates until the stopper portion without displacement to right and left. Also, a pair of slopes are connected by an interval adjustment mechanism that adjusts the interval between them,
It corresponds to support shafts having different lengths (claim 3).

The setup before processing is completed by passing b2 through the punch body 3 and winding it around the core b1. After the setup is completed, punch processing starts. First, after the soft sheet b2 is clamped by the two clamp arms 34a, the sheet transfer sections 34 are slightly separated from each other to be in a stretched state. While maintaining this state, the sheet transport units 34 are moved to a desired punching position in the X-axis direction, and the punching unit 31 is moved to the desired punching position in the Y-axis direction to perform punching. Such an operation is repeated to punch a desired pattern.

When the processing is completed, the sheet transfer section 34 on the feeding side is set to the unclamped state, and then the sheet transfer section 34 on the winding side is moved in the X-axis direction. Sheet transfer unit on the winding side

By providing driving means for applying the driving force of the claw movement to the part, the support shaft in the loosely fitted state just inserted through the raw material roll is placed on the slope, and only by operating the driving means, the rotating shaft becomes At the same time as the support shaft is supported, the claws can protrude inside the roll web to fix the roll, so that a series of setting operations can be performed in a short time. According to the third aspect, by providing the scale on the support shaft, the support shaft can be easily inserted to a predetermined position without using another measuring instrument. The roll material can be set with a desired accurate positional relationship without shifting left and right by placing the guide portion so engaged with the slope. In addition, since the interval between the pair of slopes is adjustable, it is possible to cope with a web having a width corresponding to the support shafts having different lengths.
