[Detailed description of the invention] "Industrial application field" This invention relates to a liner forming device for supplying a liner material into a cap shell such as an aluminum cap and molding the liner material by stamping. The present invention relates to a liner forming device suitable for caps.

``Prior Art'' Generally, a liner forming apparatus as shown in FIG. 6 is used to attach a liner to a cap shell such as an aluminum cap.

Reference numeral 1 in the figure is a liner forming device. This liner forming device 1 has a cap shell 2 at the peripheral edge.
A rotary conveying device 5 equipped with a star wheel 4 formed with engaging portions 3, 3... that engage with the capsels 2, 2... is rotated as described above from a predetermined position (capsel supply position A). A cap shell supply device 6 that supplies the liner material to the rotary conveyance device 5, and a liner material supply device 8 that supplies the liner material 7 into the cap shells 2, 2 that are conveyed by the rotary conveyance device 5.
and an embossing device that receives the cap shell 2 that has been conveyed to a predetermined position (embossing device connection position C) by the rotary conveyance device 5, and performs embossing of the liner material 8 supplied into the capsule 2. It is composed of 9.

The rotary conveyance device 5 transports the cap shells 2, 2... in the shape of a cylinder with a bottom, which are supplied from the cap shell supply position A with the opening side facing upward, using a star wheel rotating in the direction of the arrow in the figure. 4, and is continuously conveyed in the direction along the peripheral edge of the star wheel 4. A high frequency heating device 1 is installed at the bottom of this rotary conveyance device 5.
0 is arranged, and the cap shells 2, 2, . As shown in FIG. 7, the liner material supply device 8 extrudes the liner material 7 made of thermoplastic resin to the outside through the extrusion port 11, and the rotating cutting blades 12, 12 move the liner material 7 to the desired location. It is designed to cut only a fixed amount and supply it into the cap shells 2, 2, . . . . Embossing molding device 9
The cap shells 2, 2... are transported by the rotary transport device 5 to the embossing molding device connection position C.
The liner materials 7, 7, etc., which are received and supplied inside the cap shells 2, 2, are heated and stamped into a sheet-like liner using a stamping machine (not shown).

The liner attachment to the cap shell 2 by the liner forming apparatus 1 described above is carried out as follows. First, the cap shells 2, 2, . . . are continuously supplied to the cap shell supply position A of the rotary conveyance device 5. The cap shells 2, 2, . . . are transported to a liner material supply position B while being heated by a high frequency heating device 10, and a predetermined amount of liner material 7 is supplied at this position. The cap shells 2, 2, . . . supplied with the liner material 7 are received by the embossing device 9 at the embossing device connection position C. The cap shells 2, 2... entered the embossing molding device 9,
The liner material 7 supplied inside the cap shell 2 is heated, and the liner material 7 is embossed using an embossing machine, whereby a sheet-like liner is pasted inside the cap shell 2. Become.

"Problems to be Solved by the Invention" When the above-mentioned liner forming apparatus 1 uses a ring pull cap in which a ring part is formed on the cap body as a cap, it has a function of keeping the direction of the ring part constant. Because it is not held in place, when the ring pull cap is transported by the rotary transport device 5, the ring portion may collide with the mouth of the liner material supply device 8, deforming the cap, or the liner material supply position C may be There was a problem that problems such as misalignment were likely to occur.

This invention solves the above-mentioned problems, prevents troubles such as the ring part colliding with the liner material supply device 8 even when using a ring pull cap as a cap, and allows continuous liner application. It is an object of the present invention to provide a liner forming apparatus that can perform the following steps.

``Means for Solving the Problems'' This invention is based on the above-mentioned liner forming apparatus, in which the star wheel of the rotary conveyance device has a smaller outer diameter than the star wheel and accommodates the ring portion of the ring pull cap. It is characterized by the provision of two star wheels.

"Operation" The liner forming device of this invention accommodates the ring portion of the ring pull cap in the second star wheel provided in the star wheel 4 of the rotary conveyance device 5, and this ring portion collides with the liner material supply device, etc. The ring-pull cap can be transported by holding it in a direction that would not allow the ring-pull cap to move.

"Embodiment" FIGS. 1 to 3 are diagrams showing an embodiment of this invention. In these figures, the same elements as those shown in FIGS. 5 and 6 are designated by the same reference numerals, and their explanations will be omitted.

The liner forming apparatus 1a described here is the sixth
The difference from the liner forming apparatus 1 shown in the figures and FIG.
Another feature is that a second star wheel 15 is provided which has a smaller outer diameter than this and accommodates the ring portion 14 of the ring pull cap 13. Accommodating portions 16, 16, . . . for accommodating the ring portion of the ring pull cap 13 are formed at the peripheral edge of the second star wheel 15. This second star wheel 15
are disposed on the first star wheel 4 with their rotational axes aligned with each other, and rotate at the same angular velocity as the first star wheel 4. Further, the second star wheel 15 has a housing portion 16 that holds the ring portion of the ring pull cap 13 supplied from the cap shell supply position A in a state facing inward in the radial direction of the first star wheel 4. It is now possible to transport it. The ring pull cap 13 supplied to the cap shell supply position A of the rotary conveyor 4 is located at the fourth
The ring pull cap feeding device 18 shown in FIGS.
The ring portion 14 is supplied with the ring portion 14 facing inward in the radial direction of the star wheels 4, 15.

Liner pasting on the ring pull cap 13 using the liner forming apparatus 1a described above is carried out as follows. First, the ring pull cap supply device 18 continuously supplies the ring pull cap 13 to the cap shell supply position A of the rotary conveyance device 5a with its ring portion 14 facing inward in the radial direction of the star wheels 4 and 15. do. The ring pull cap 13 supplied to the rotary conveyance device 5a,
13..., the cap main body 17 engages with the engaging portions 3, 3... of the first star wheel 4,
The ring portion 14 is accommodated in the accommodating portions 16, 16, . . . of the second star wheel 15, and is continuously conveyed in the direction of the arrow shown in FIG. The ring pull caps 13, 13, . . . are transported to the liner material supply position B while being heated by the high frequency heating device 10 on the way. At this liner material supply position B, the ring pull caps 13, 13, . . . are continuously supplied with a predetermined amount of liner material 7 by the liner material supply device 8. It is transported to C. The ring pull caps 13, 13, .
is heated and then continuously pressed to form a sheet-like liner.

The above-mentioned liner forming device 1a has a ring portion 1 of a ring pull cap 13 in a rotary conveying device 5a.
4 and can hold the ring pull cap 13 in a predetermined direction.
When transporting the liner material 3, it is possible to prevent troubles such as the ring portion 14 colliding with the liner material supply device 8.

"Effect of the invention" The liner forming device of this invention accommodates the ring portion of the ring pull cap in the rotary conveying device,
Since a second star wheel is provided that can hold the ring pull cap in a predetermined direction, troubles such as the ring portion colliding with the liner material supply device when transporting the ring pull cap are avoided. It can be prevented.
