Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the structure of a take-up reel made of a dambole such as a connector.

[0002]

[Prior art]

 Up to now, the winding reels made of dambolle, which are schematically shown in FIGS. 3 to 6, have been implemented, but each has the following drawbacks.

FIG. 3 shows a structure in which the left and right circular flanges made of danboles and the paper tube are caulked at the center with metal fastening fittings. The number of parts is large, and production efficiency and economic efficiency are high. It is bad, and the time and effort for separating the fasteners are added at the time of disposal.

FIG. 4 shows a structure in which right and left circular flanges made of danboles are adhered or welded to a foam styrol board instead of a paper tube, and the number of parts is small and the adhesion is sure and easy. However, since the Styrofoam is flexible, it has the advantage of preventing deformation and damage of the rolled product at the beginning of winding, but on the other hand, it takes time and labor to separate the Styrofoam board at the time of discarding and to dispose of it.

FIG. 5 shows a simple structure in which right and left circular flanges made of dambolle are bonded to a paper tube with an adhesive. The number of parts is small and the economy is high, but the strength is poor and the deformation is weak. In addition, smoothness of winding and feeding is lacking.

FIG. 6 is to supplement the defect of the state of FIG. 3, in which reinforcing members (paper tube retainers) are adhered to both edges of the paper tube inner diameter and in contact with the circular flange, but the strength is increased. In addition, it is weak against deformation, the number of parts increases, and the production efficiency decreases.

[0007]

[Problems to be solved by the device]

 The present invention has been made in view of the actual situation of each conventional reel, and is strong and free from deformation such as warpage, smooth winding and unwinding, and the number of parts in the manufacturing process. It is intended to provide a take-up reel such as a connector which brings little productivity and economical efficiency.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the take-up reel made of a dambole such as the connector of the present invention has circular flanges 2 and 3 made of right and left damboles and a diameter of one third or more of the diameters of the circular flanges. And the circular paper tube 1 having the above-mentioned structure, and the left and right circular flanges 2 and 3 are crossed at right angles with the direction of the Danboule wave to obtain a circular vinyl tube 1 having a high initial adhesive strength in a vinyl acetate system. And the inner side surfaces of the left and right circular flanges of the outer peripheral portion of the circular paper tube 1 are crushed 4 and are bonded together by a conductive adhesive.

[0009] In the above, for adhesion with a vinyl acetate-based neutral adhesive, a gun is arranged and 360 degrees is applied by rotating the pallet side driven by the direct drive servomotor once. Can be carried out smoothly and quickly and with a uniform coating amount.

[0010]

[Effect of device]

 As described above, the Danboel take-up reel obtained by the present invention has three parts, namely the right and left Danboru circular flanges and the circular paper tube, and the diameter of the circular paper tube is three. Since the diameter of the circular flange is one-third or more, and the left and right circular flanges are bonded to the circular paper tube by intersecting the square wave directions at right angles, it is possible to effectively prevent deformation such as warpage of the flange. Moreover, since the adhesion was made with a vinyl acetate-based neutral adhesive, which has a high initial adhesive strength, it can be firmly and quickly integrated without being affected by temperature changes, and the material will be destroyed if peeling is attempted. Adhesive effect can be obtained. Further, since the inner surfaces of the left and right circular flanges on the outer peripheral portion of the circular paper tube are crushed and crushed, it can be wound and unwound smoothly. In terms of the manufacturing process, it is very advantageous as it can provide a winding reel with a high precision, which has a small number of parts and brings productivity and economy.

【Example】

 As shown in FIG. 1, it is composed of three elements of left and right (upper and lower in FIG. 1) dumbbell-shaped circular flanges 2 and 3 and a circular paper tube 1 having a diameter of a third of the diameter of the circular flanges. As shown in the figure and FIG. 2, the left and right circular flanges 2 and 3 are crossed at right and left directions of the Danboule wave so that vinyl acetate having a high initial adhesive force is attached to each side surface of the circular paper tube 1. Bond with a neutral adhesive. Further, as shown in FIG. 2, a take-up reel made of a dambole such as a connector formed by crushing the corresponding inner surfaces of the right and left circular flanges on the outer peripheral portion of the circular paper tube 1 by chamfering. .
