Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Applicability] The present invention relates to a magazine for rolled materials used for printing, printing, copying, etc.

[Technical background of the invention and its problems]

Conventionally, a relatively wide magazine for rolled materials used for printing, printing, copying, etc., as shown in FIG. A roll-shaped material 3 is housed in a hollow interior formed by a cap 4, and the rolled material 3 is pulled out from a slot 2 extending along the axial direction of a winding core 5 at a corner of one side of the body portion 1. It is a magazine (for example, Tokko Sho 59-
(See Publication No. 36736).

The rolled material 3 is stored with the tip of the rolled material 3 pulled out from the slot 2 of the magazine, and the tip is fastened with tape 10, for example, on the body of the magazine to prevent it from being rewound into the magazine. It is being and,
For example, when loading a magazine into a magazine mounting section of an image forming apparatus, etc., the tape 10 is peeled off, and the leading edge of the photosensitive material 3 is caught, for example, by a conveyance nip roller of the image forming apparatus, so that the photosensitive material 3 can be pulled out. It will be done. Also,
The bearing hti for receiving the winding core 5 has a cylindrical shape, and supports the winding core 5 by its cylindrical surface.

Here, as the material for the body portion 1, for example, cardboard or plastic is used.

The two end caps 4 that seal both ends of the body portion 1 have structural features such as a groove that engages with the edge of the body portion 1 to keep out light, and a rotation bearing for the core 5 of the photosensitive material 3 housed in the magazine. It has relatively complex irregularities and is required to have the necessary rigidity and accurate dimensions, so it is usually made of a general injection molding material such as plastic.

When such a magazine for rolled materials is subjected to vibrations during transportation, the core 5 and the bearing are circular and contact at one point, so the core 5 swings on the cylindrical inner surface of the bearing, causing the rolled material to gradually shake. As the roll rotates, the roll becomes loose. When this winding slack increases, the rolled material and the inner wall of the magazine rub against each other, causing damage to the surface of the rolled material. In addition, even if there is no slack in the winding, if the rolled material rubs against each other during transportation, or furthermore, if the rolled material is pulled out from the magazine as described above, it will be necessary to tighten the winding. The materials may rub against each other, causing scratches on the surface of the rolled material.The surface of the rolled material normally used in image forming devices is often relatively easily scratched, and the final forming There is a problem that this scratch appears in the image.

As a countermeasure to this problem, Japanese Patent Application Laid-open Nos. 60-156058 and 5
No. 7-128333 K, key (lock) as shown in each publication
A method has been proposed in which the roll core is fixed to the core bearing part of the end cap of the magazine, which is the core of the roll, to prevent the core from rotating before the cassette is used for the first time. This increases the number of extra steps, such as requiring a special structure or using special tools to perform special steps in the magazine assembly stage.

[Purpose of the invention]

An object of the present invention is to solve the above-mentioned problems, and to provide a magazine for rolled materials that suppresses rotation of the core due to vibration during transportation and has a simple structure.

[Means for solving problems]

The present invention has achieved the above-mentioned object by storing a rolled material wound around a core pivotally supported on the inner surface of the end cap in a hollow interior consisting of a cylindrical body part and two end caps sealing both ends of the body part. In the magazine for rolled materials, in which the rolled material is drawn out of the magazine from a slot extending along the core axis at a corner of one side of the body part, a bearing is provided on the inner surface of the end cap to support the core at two points. This is achieved through a configuration with

That is, by providing two support points for the core on the inner surface of the bearing, swinging of the core axis and rotation of the core due to vibration of the magazine are suppressed.

[Embodiment]

Embodiments of the present invention will be described using figures.

FIG. 1 is an exploded perspective view showing an embodiment of the magazine for rolled materials of the present invention.

A roll material 3 wound around a winding core 5 is housed in the center of a rectangular body portion 1 of the magazine for rolled material. The rolled material 3 is pulled out of the magazine by passing between the upper lip 6 and the lower lip 7 of the slot 2 extending in the axial direction of the core 5 at the corner of one side of the body part 1, and the tape 1 is placed on one side of the body part 1.
Pasted by 0. End cap 4 is indicated by arrow X,
Both open ends of the body portion 10 are sealed from the Y direction. At this time,
The winding core 5 enters the bearing 8 and is pivotally supported.

A front view of the end cap 4 is shown in FIG. There is a bearing 8 in the center of the end cap 4, and a total of four ribs 9 extend in the normal direction of the bearing 80 at positions where the diagonal line connecting the apex angles of the flanges 11 of the end cap 4 and the inner surface of the bearing 8 intersect. It is provided.

When this magazine is transported, it is stacked with one side of the seven langes 11 facing down, and the weight is evenly distributed between the two ribs 9 corresponding to the corners at both ends of that side, and the core 5 is placed on the shaft. be supported. Since there are two fulcrums in this way, K, winding core 5
Transverse vibration and even longitudinal vibration for a bearing of 1gK are sufficiently prevented.

Considering transverse vibration and longitudinal vibration, as in this embodiment,
It is optimal to arrange each rib 9 symmetrically at an angle of 45° with respect to the direction of gravity from the center of the bearing 8, but if the weight is distributed between the two ribs, how can the ribs 9 be arranged? is also valid. Also, in Figures 1 and 2, 7
The four ribs 9 are arranged in the above-mentioned manner in order to provide the same pivot support even when the lunges 11 are stacked with either side facing down, but the number of ribs may be more or less than four. can also be effective. Furthermore, it is also effective to use the rib 9 as a protrusion such as a semicircle.

FIG. 3 shows a front view of the end cap 4' in another embodiment. The bearing 8' is not circular, but is square with an apex on the bisector of each side of the seven flange 11'.

When the seven langes 11' are placed with either side facing down in this magazine, the winding core 5 is pivotally supported by contacting two adjacent sides of the bearing 8'. Therefore, the same effect as the end cap 4 of FIG. 2 can be obtained. The bearing 8' may have a shape in which the portion in contact with the winding core 5 is straight or swells toward the winding core 5, and does not need to have an apex angle. In this case, the portions of the bearing 8' in contact with the winding core 5 are preferably arranged symmetrically at angles of 45° with respect to the direction of gravity from the center of the bearing 8', similar to the end cap 4 in FIG. However, if the weight from the winding core 5 is distributed to two points,
No matter what shape it is, a certain degree of effect can be obtained. Therefore, it is also effective to use a polygonal shape such as a hexagonal shape for the bearing.

In the embodiment described above, in addition to suppressing the vibration of the winding core relative to the bearing IK, there was an effect of reducing the drawing resistance when drawing the roll-shaped material from the magazine.

In this embodiment, a rectangular magazine is taken as an example, but it is also applicable to a polygonal column type such as an octagonal column type, an octagonal column type, or a cylindrical magazine.

〔Effect of the invention〕

As mentioned above, the bearing for a magazine for rolled materials has two points on the inner surface that act as fulcrums for the core, which prevents the core from vibrating horizontally and vertically and rotating within the bearing due to vibrations during transportation. , no need to use special parts or tools,
The winding can be prevented from loosening with a very simple structure.
