Abstract

(57) [Abstract] [Purpose] The purpose of the present invention is to easily attach and detach the core tube and the collar piece in the winding drum by utilizing the deformation and straining action of the fitting. [Structure] A core tube and a pair of collar pieces having a through hole having substantially the same inner diameter as the inner diameter of the core tube is formed in the center part. The through hole of the collar piece and the inner diameter of the core tube are combined to form a collar. In the take-up drum where one piece is applied to the end of the core tube, and this is clamped and attached by the mounting bracket,
The mounting metal fitting is divided into a large number by a notch groove from an edge portion of a circular flat plate to a circumferential position matching the inner diameter of the core tube, and a plurality of equally divided pieces of the divided pieces are pressed pieces of the collar piece. The remaining divided pieces are bent to form a crimping piece that fits into the inner wall of the core tube and presses against it.Furthermore, the inside of the notched circumference is slightly curved and bulges out, and at the center there is a shaft. A support hole is punched and the pressing member is bent, and the pressing piece is applied to the outside of the flange piece applied to the end of the core tube, and a crimping piece is fitted to the inner diameter of the core tube to fix the bulging portion. It is pressed and deformed, and by this deformation strain action, the crimping piece is expanded and crimped to the inner wall of the core tube, and the pressing piece presses the brim piece.

[Industrial applications]

 TECHNICAL FIELD The present invention relates to a collar mounting bracket for a winding drum, which mounts the flange piece of the winding drum with a collar for winding a long body such as an electric wire on a winding drum.

[0002]

[Prior Art]

 A conventional winding drum for winding a long body is a core tube made of paper pieces with through holes on both sides of the core tube that are adapted to the inner diameter of the core tube. The flange piece is pressed from the outside of the flange piece to the inner wall of the core tube and a pair of holding bodies provided with the flange at the edge of the flange piece to press and fix the flange piece.

Therefore, in order to wind the long body, the shaft supporting hole formed at the center of the holding body is fitted to the shaft protruding from the support body, and the winding drum is rotated to wind the long body. It was

However, when inspecting or inspecting the long body wound on the winding drum, the flange piece made of paper is forcibly opened and inspected, and once it is inspected, the open portion becomes habitless and unusable. Therefore, it was uneconomical because it was useless once.

[0005]

[Problems to be solved by the device]

 As described above, the conventional winding drum is uneconomical because it cannot be reused if the long piece that has been wound up is bent and the collar piece made of paper is inspected for inspection. . Therefore, it has been desired that the flange piece of the take-up drum can be easily removed and easily attached after the inspection.

[0006]

[Means for Solving the Problems]

 The present invention has been made in view of the above circumstances in order to solve this problem, and in the above-mentioned mounting bracket for a winding drum, which is composed of a core tube, a pair of collar pieces and a mounting bracket, The notch is divided into a number of notches up to the circumferential position that approximately matches the inner diameter of the core tube, and the inside of the notched circle is slightly curved to provide bulging parts. A plurality of divided pieces that are put together are used as pressing pieces of the collar piece, and the remaining divided pieces are crimp pieces that press-contact with the inner wall of the bent core tube. (EN) Provided is a fitting for pressing the inner wall of a core tube and a collar piece by a deforming action to mount the core tube and the collar piece.

[0007]

[Action]

 According to the present invention, the inner diameter of the core tube 1 and the through holes 2 and 2 of the pair of flange pieces 3 and 3 are brought into contact with the core pieces 1 and 3, and then the core pieces 1 and 3 are respectively contacted from outside. The crimping pieces 7 and 7 are fitted in the core tube 1 so as to be positioned, and the pressing pieces 6 and 6 are applied to the outer surfaces of the brim pieces 3 and 3 to fix the curved bulging portion 4a formed on the mounting hardware 4 and 4. When pressed, the bulging portion 4a is deformed, and due to the action of this deformation strain, the crimping pieces 7, 7 are respectively expanded, the crimping pieces 7, 7 are pressed against the inner wall of the core tube 1, and the pressing pieces 6, 6 are flanged pieces. The winding drum is constituted by pressing 3, 3 and crimping them to the end surface of the core tube 1. When the long piece is wound on the take-up drum and the long piece is to be inspected, the crimp pieces 7 and 7 are reduced by restoring the deformed and deformed portions of the fittings 4 and 4 in order to remove the collar pieces 4 and 4. The collar pieces 4 and 4 that are released from the pressure contact and held between them can be easily removed for inspection and inspection.

【Example】

 FIG. 1 shows an embodiment of a collar mounting member for a winding drum according to the present invention, which will be specifically described with reference to the drawings.

Reference numeral 1 denotes a take-up core tube, and a pair of flange pieces 3 each having a large diameter and having a through hole 2 having the same diameter as the inner diameter of the core tube 1 respectively at the center are provided at both ends of the core tube 1. 2 is applied so as to match the inner diameter of the core tube 1, and this flange piece 3 is attached to the core tube 1 by a mounting member 4.

The fittings 4 are each formed of a steel flat plate that is cut into a circular shape. From the edge of the flat plate to the circumference that substantially matches the inner diameter of the core tube 1, there are a number of notched grooves 5 from the edge side. The plurality of divided pieces are equally spaced and used as pressing pieces 6 for pressing the collar piece 3, and the remaining divided pieces are bent to form a crimping piece 7.

Further, an inner portion of the circumference of the mounting metal fitting 4 which is cut out by the cutout groove 5 has a slightly curved bulging portion 4a, and the pressing piece 6 is provided on the left and right sides of the tip end portion. In addition to providing the pawls 6a, 6a, the pressing piece 6 is bent at an angle from the curved portion and is bent, and the bent portion is provided with a reinforcing rib 6b for maintaining a certain refraction.

Further, the crimping piece 7 is formed so as to become narrower toward the tip end portion, and the tip end portion is cut and raised to provide a locking claw 7a so as to be embedded in the inner wall of the core tube 1 at the time of pressure contact. The curved bulging portion 4a is deformed when pressed, the crimping piece 7 is expanded in the expanding direction by the deformation strain action, and the pressing piece 6 acts in the pressing direction. FIG. 5 is a deformation of the pressing piece 7, and both sides of the crimping piece 7 are made parallel, and the tips on both sides are cut and raised to form locking claws 7a, 7a.

[0013]

[Effect of the device]

 As described above, the collar mounting fitting of the winding drum of the present invention is provided with the curved bulging portion and the bending crimping piece and the pressing piece, and the bulging portion is pressed to expand the core by the deformation and strain action. By holding the crimping piece in pressure contact with the inner wall of the pipe and pressing and holding the flange pieces that touch both ends of the core tube, the flange piece can be easily attached to the core tube, and inspection and inspection of the rolled long body can be performed. However, the collar piece can be easily removed by restoring the deformation and strain action without bending it, and it can be reused without the uneconomical disadvantages of the past. It also has the effect that it can be easily used to change the width of the core tube.
