Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flange structure for a roll-shaped product, comprising a first flange member mounted on both ends of the roll-shaped product, and a second flange member inserted into the first flange member. Also, the present invention relates to a method and an apparatus for mounting a flange structure for a roll-shaped object for inserting the second flange member into the first flange member.

[0002]

2. Description of the Related Art For example, a film used in the field of plate making is provided with flange members at both ends of a roll-shaped photosensitive material in which a long photosensitive material sheet is wound around the outer periphery of a winding core, and a light-shielding sheet ( A light-shielding leader) is configured as a light-shielding photosensitive material roll wound around the outer periphery of the roll-shaped photosensitive material.

Regarding this type of light-shielding photosensitive material roll,
Various proposals have been made in the past, for example, a patent application has been filed by the present applicant in order to easily manufacture the light-shielding photosensitive material roll (Japanese Patent Application No. 11-50946).
No.).

In this application, specifically, as shown in FIG. 21, a length of a photosensitive material roll (roll-shaped material) 1 with a disc-shaped light-shielding member (flange member) 2 attached to both ends thereof is used. Long heat-shrinkable light-shielding reader 3 that heat-shrinks in the direction
Is wrapped around, and the end portion of the light-shielding leader 3 is fixed via the tape 4. Next, for example, the photosensitive material roll 1 is introduced into the shrink tunnel in order to heat and contract the light-shielding leader 3. Therefore, the light-shielding leader 3 is thermally contracted, and both ends of the light-shielding leader 3 and the outer surface of the disk-shaped light-shielding member 2 are brought into close contact with each other, and the light-shielding photosensitive material roll 5 is manufactured.

By the way, in the light-shielding photosensitive material roll 5 of this type, the flange member 6 is mounted in the disc-shaped light-shielding member 2 in relation to the device in which the light-shielding photosensitive material roll 5 as a product is loaded. There are cases. At this time, the groove portion 7 is formed on the inner peripheral surface of the disc-shaped light shielding member 2, and the protrusion portion 8 is provided on the outer peripheral surface of the flange member 6 from the tapered portion 6a to the straight portion 6b. Therefore, the flange member 6 is rotated so that the protrusion portion 8 of the flange member 6 is aligned with the groove portion 7 of the disc-shaped light shielding member 2, and the flange member 6 is inserted into the disc-shaped light shielding member 2.

[0006]

However, in general,
The inner diameter of the disc-shaped light-shielding member 2, the outer diameter of the flange member 6, or the shapes (roundness, etc.) of the disc-shaped light-shielding member 2 and the flange member 6 themselves are likely to change. Therefore, when rotating the flange member 6 while inserting the tapered portion 6a of the flange member 6 into the disc-shaped light shielding member 2, the protruding portion 8 of the tapered portion 6a gets over the groove portion 7, and the protruding portion 8 is formed. The flange member 6 may be inserted into the disc-shaped light shielding member 2 in a state where the groove portion 7 and the groove portion 7 do not match.

As a result, there is a problem that the flange member 6 cannot be easily removed from the disc-shaped light-shielding member 2 when the component is to be recycled after the light-shielding photosensitive material roll 5 has been used.

Furthermore, since the engagement condition between the disc-shaped light-shielding member 2 and the flange member 6 greatly varies, the torque for rotating the flange member 6 tends to be insufficient. For this reason,
There is a problem that the torque generating means becomes large in size, and the mounting device for the flange member 6 becomes large in size.

The present invention solves this kind of problem, and the groove portion of the first flange member and the protrusion portion of the second flange member can be surely and easily aligned with each other and has a simple structure. It is an object of the present invention to provide a flange structure for a roll.

Further, according to the present invention, the groove portion of the first flange member and the protrusion portion of the second flange member can be surely and easily aligned with each other with a simple process and structure, and the efficiency of the mounting work of the flange structure can be improved. It is an object of the present invention to provide a method and an apparatus for mounting a flange structure for a roll-like object that can be realized.

[0011]

In the flange structure for a roll-like object according to the present invention, the inner peripheral surface of the first flange member is
A plurality of grooves extending in the axial direction are formed at predetermined angular intervals, and at the second flange member insertion side end of the inner peripheral surface, an opening diameter is increased to form a step. It is provided. On the other hand, the outer peripheral surface of the second flange member is provided with a taper portion whose diameter decreases toward the front end in the insertion direction and a straight portion which is continuous from the diameter-increasing side end portion of the taper portion. Then, in the second flange member, at a portion separated from the reduced-diameter side end portion of the taper portion to the straight portion side by a predetermined distance, the second flange member rises radially outward corresponding to the opening diameter of the step portion,
In addition, a plurality of protrusions extending along the straight portion are formed corresponding to the grooves.

Therefore, when the second flange member is inserted into the first flange member under the guiding action of the taper portion, the protrusion provided on the second flange member causes the protrusion portion provided in the first flange member to move. It is supported in contact with a step provided on the peripheral surface. Therefore, when the second flange member is rotated, the second flange member is moved to the first position at the position where the protrusion matches the groove.
It is inserted into the flange member. Accordingly, the protrusion and the groove can be accurately and surely aligned with each other, and the second flange member can be inserted into the first flange member with high accuracy.

Here, on the inner peripheral surface of the first flange member,
A notch for guide is provided that is inclined and communicates from the step portion to the tip side of the groove portion in the rotational direction when the second flange member is inserted into the first flange member. Therefore, when the second flange member is rotated, the protrusion of the second flange member is smoothly and surely inserted into the groove under the guiding action of the guide cutout portion, and the protrusion forms the groove. It is possible to effectively prevent overcoming.

Further, in the method and apparatus for mounting the flange structure for a roll-like object according to the present invention, the second flange member is maintained so as to be movable back and forth with respect to the insertion actuator.
The second flange member is rotated while the flange member is pressed against the first flange member side only via the biasing member. Then, after it is detected that the second flange member has moved into the first flange member by matching the groove portion and the protrusion portion, the second flange member moves into the first flange member under the action of the insertion actuator. Is inserted.

As described above, since the second flange member is rotated while being pressed toward the first flange member via the biasing member, the rotational torque of the second flange member can be kept constant. it can. This urging member includes a cylinder that supports the second flange member gripping chuck provided on the insertion head so as to be movable back and forth with respect to the insertion head, and the rotational torque of the insertion head is reliably maintained.

Further, since it is detected that the second flange member has moved into the first flange member, it is possible to surely and easily detect that the groove and the protrusion are aligned. Therefore, the second flange member can be inserted into the first flange member with high accuracy and efficiency with a simple process and configuration.
