なつている。 As shown in FIGS. 3A, B, and C, the conventional cap sealing head has a container opening 1a having a spiral groove 2 formed by a spiral strip 2a on the upper outer peripheral surface of the container 1. The material 3 is covered with a material 3, and the material 3 is pressed from the outside with a plurality of forming rolls 4 (only one is shown in the figure) at the arrow F, and the forming rolls 4 revolve around the material 3 and rotate on their own axis. Then, the material 3 is pushed into the threaded groove 2 with the forming roll 4, and is guided by the threaded groove 2 and advances downward in the figure.
The cap sealing head is formed into a screw-like shape to form a screw cap, and the cap sealing head is further described in detail with reference to FIG. The roll shaft 4a of the forming roll 4 is vertically slidably and rotatably inserted into the spring holder 9 with a snap spring 9a attached to the upper part of the roll shaft 4a, and a spring 6 is inserted between the bush 5 and the spring receiver 9 with a snap spring 9a attached to the upper part of the roll shaft 4a.
In addition, a plurality of disc springs 8 are interposed between the lower surface of the bush 5 and the forming roll 4, and the forming roll 4 is in contact with the spiral groove 2 of the container opening 1a. or when the top of the spiral thread 2a contacts the lower position a in the figure as shown in FIG . , Figure 3C
As shown in the figure, when the spiral strip 2a comes into contact with the upper position b in the figure, the disc spring 8 is compressed and moves as indicated by the arrow b 1 in the figure.
As the lever 7 revolves around the material 3, the forming roll 4 compresses the spring 6 and descends, applying forming pressure to the material 3 and forming the threaded groove 2. When the molding is completed, the lever 7 is molded into a screw shape corresponding to the
The forming roll 4 is separated from the material 3 through the spring 6, and is lifted up by the spring 6 to return to its original state.

作業が必要になるなどの欠点がある。 However, in the conventional cap sealing head, the forming of the screw cap by the forming roll is frequently repeated at high speeds, which causes the spring to become fatigued and damaged, and the spring to be rotated by friction against the spring receiver or bush. There are drawbacks such as wear and tear, and the tendency for foreign matter, liquid, etc. to adhere to the inside and outside of the spring, requiring troublesome cleaning work.

キヤツプシーリングヘツドを供する点にある。 The present invention is an invention to eliminate the above-mentioned drawbacks of conventional cap sealing heads, and includes:
In a cap sealing head in which a roll shaft of a forming roll is slidably inserted into a lever, the lever is made of a non-magnetic material and a magnetic material portion is provided on one side of the roll shaft, and the other side of the roll shaft is provided with a magnetic material portion. The roll shaft of the forming roll is slidably inserted into the lever, and is characterized by a structure in which a magnet is placed in the lever portion of the lever so that the roll shaft is slidably biased toward the other side by magnetic force. The slide of the roll shaft is biased by the magnetic force between the magnetic material part provided on one side of the roll shaft and the magnet placed on the other side of the roll shaft. The biasing mechanism has been extremely simplified, and the rotation and sliding performance and operational reliability of the roll shaft and forming roll have been improved, and the adhesion of foreign matter, liquid, etc. has been significantly reduced, making cleaning easier. The object of the present invention is to provide a cap sealing head that eliminates the drawbacks.

Due to the magnetic force generated by the interaction between the magnet 30 and the ferromagnetic material provided at the lower end of the roll shaft 14a, the roll shaft 14a is urged to slide upwardly in the drawing together with the forming roll 14, as shown in FIG. The structure is such that it has a simple layout.

勢になる。 The illustrated embodiment of the present invention has the above-mentioned structure, and to explain the operation and effect, the forming roll 14 of the embodiment shown in FIG. 1 is placed over the container opening as shown in FIG. 3. The molded material 3 can be molded into a screw cap. When the forming roll 14 is guided by the spiral groove 2 at the container opening and moves in the roll axis direction to form a screw shape, the forming roll 14 is moved between the magnet 30 and the magnetic material provided on the roll shaft 14a. The roll shaft 14a slides downward in the drawing against the applied magnetic force (the force FS is substantially applied), and when the forming is completed, the forming roll 14 is screwed up by an appropriate mechanism (not shown). When released from the cap, the forming roll 14 is raised relative to the lever 17 via the roll shaft 14a by the magnetic force, and is automatically returned to its original state to be ready for the next screw cap forming.

る。 As mentioned above, in the present invention, the mechanism for sliding the roll shaft of the forming roll (upward in the figure) is composed of a magnetic body provided on the roll shaft side and a magnet placed opposite to it, so that the forming roll and Even if the roll shaft rotates and moves in the axial direction at high speed and is frequently repeated, there is almost no damage to the magnets, etc., and the sliding biasing mechanism of the roll shaft is extremely simplified. A predetermined magnetic force is always applied to the shaft, increasing its rotation and movement performance, significantly improving the molding performance and operational reliability of the screw cap, and significantly reducing the adhesion of foreign objects, liquids, etc. This has the effect of making cleaning easier. Note that the forming roll can be rotatably mounted on the roll shaft, and in this case, the roll shaft is only slidably mounted on the lever.
