[Industrial applications]

 The present invention is a wrapping plate of a seaweed winding machine composed of four or five rectangular plates, which is sandwiched between adjacent rectangular plates and is expanded by energizing and expanding the wrapping plates in a flat shape. This relates to a separate mounting structure for compression springs.

[0002]

[Prior art]

 In the seaweed winding machine P shown in FIG. 3, the conventional wrapping plate 5 has four or five rectangular plates 5p attached to each other as shown in 4-1 and 4-2 of FIG. 4 (both of which are rear views). They are formed so as to be refractably connected to each other via 5f. Further, a torsion spring 5d is interposed between the adjacent rectangular plates 5p, 5p, and both ends of the spring 5d are held by holding members 5h fixed to the back surface of each rectangular plate 5p. However, since the warp prevention plate 5g is installed on the back surface of each rectangular plate 5p across the adjacent rectangular plates 5p, 5p, the wrapping plate 5 has a flat shape. It is impossible to bend in the opposite direction beyond, and it is urged to expand in a plane. Further, on the back surface of the rectangular plate 5S at the side end, a claw portion 5e whose operation will be described below is formed so as to rise inward.

The winding plate 5 has a rectangular plate 5u at the center thereof connected to a lifting rod 5a of a lifting device 16 as shown in FIG. The ascending / descending rod 5a is vertically slidably fitted into the central portion 17 of the machine body B, and the receiving plate portion 12 is extended above the rectangular parallelepiped cylindrical body 11 erected at the central portion 17 to form a rectangular parallelepiped concave portion 5C. Move up and down in the center of. A drive unit M5 is placed below the machine body B and rotates a rotary disk 14 having an eccentric groove cam 5b formed on the front surface. On the other hand, a roller 5R is connected to the lower end of the lifting rod 5a, engages with the eccentric groove cam 5b, and follows the groove cam 5b. FIG. 3 illustrates a state in which the rotating disk 14 has rotated once and the lifting rod 5a has returned to the upper limit position. The upper limit position is detected by the upper limit detection device 19, and the drive unit M5 is stopped. Thus, at the upper limit position, the wrapping plate 5 stops in a state where it is expanded in a plane. Next, the seaweed winding work will be described with reference to a cross-sectional view (FIG. 3) of the main part of the seaweed winding machine P. The plate-shaped cooked rice 8 is wound by the conveyor 2 of the cooked rice feeder A installed on the machine body B, and the seaweed and the ingredients are wound manually. It is supplied on top of the packaging plate 5. When the drive unit M5 is rotationally started and the lifting rod 5a is lowered, the four rectangular plates 5p connected to each other are fitted into the rectangular parallelepiped concave portion 5C, but the claw portion 5e abuts against the inlet end edge portion 5i and stops. The rectangular plate 5S at the side end is rotated inward to close the rectangular plate. The closed state is illustrated by an imaginary line. Thus, the seaweed, cooked rice and ingredients on the wrapping plate 5 are formed into a square seaweed roll. When the lifting rod 5a further rotates and returns to the upper limit position, the rectangular plate 5p bent and closed in a square shape is released from the rectangular parallelepiped concave portion 5C, and the claw portion 5e is released from the locking of the inlet end edge portion 5i. Then, the wrapping plate 5 is restored and expanded in a flat shape by the torsion spring 5d, and the formed quadrangular nori seaweed roll can be taken out freely on the expanded wrapping plate 5.

[0004]

[Problems to be solved by the device]

 The conventional wrapping plate 5 has a simple and effective structure, but since the torsion spring 5d is interposed between the rectangular plates 5p and 5p without being provided, the seaweed roll placed on the spring can be used. It was in direct contact, and if the spring was damaged during its service life, it could fall off and damage the seaweed roll or mix it into the seaweed roll. Further, the parts of the seaweed winding machine P may be damaged by being sandwiched between the wrapping plate 5 and the rectangular parallelepiped concave portion 5C.

[0005]

[Means and Actions for Solving the Problems]

 The present invention has been made in view of the above problems, and in the structure of the expanding torsion spring in which the conventional torsion spring urges and expands in a planar shape, the torsion spring has to be interposed in a bare state. Although not obtained, the present invention has a compression spring structure in which the compression spring 5m is urged and expanded in a planar shape by utilizing the spring back force when the compression spring 5m is bent laterally, and the adjacent rectangular plates 5p and 5p are respectively provided. Since the bottomed cylinders 5K, 5K are fixed to face each other, and the compression springs 5m are urged and sandwiched in the opposed cylinders 5K, 5K, the expansion compression spring is separately mounted, so that there is a problem of bare mounting. Was solved (Fig. 1). That is, according to the present invention, in the wrapping plate 5 of the seaweed winding machine P, which is composed of four or five rectangular plates 5p that are refractably connected to each other, a bottomed cylinder 5K is provided on the back surface of the adjacent rectangular plates 5p and 5p. The compression springs 5m are urged and sandwiched in the respective opposed bottomed cylinders 5K and 5K which are fixed to face each other, and can be bent by bending the springs 5m laterally in the wrapping direction. However, the wrapping plate 5 is urged and expanded in a flat shape in the opposite direction so that the spring 5m cannot be bent due to the close contact with the spring 5m. Thus, in the structure of the present invention, direct contact between the expanding compression spring 5m and the seaweed roll is avoided, and even if the spring 5m is damaged, it is contained in the bottomed cylinder 5K and can be prevented from falling off.
