Description

[Detailed description of the invention] [Industrial application field] This invention relates to a capping machine that attaches a cap to a container such as a glass bottle containing carbonated beverage, fruit juice, etc. More specifically, the cap is a roll-on cap, a crown, a lip. The present invention relates to a capping machine that can use either a cap or a pre-screw cap.

[Conventional technology]

Conventionally, a capping machine having a configuration shown in FIG. 4 has been known (for example, Japanese Patent Application No. 61-113218).
issue).

The capping machine shown in FIG. 4 is provided with a roll-on pill fur proof cap or a crown or a lip cap on which a screw is rolled after the bottle mouth is attached. It is schematically composed of a spindle-head assembly 2 for a cap and a spindle-head assembly 3 for a crown.

The turret 1 is for rotating the spindle-head assembly 2 for roll-on cap or the spindle-head assembly 3 for the crown in the circumferential direction. The turret 1 serves as a pivot axis of the spindle-head assembly 2 or 3 in the center. A central support 4 is provided.

The center support 4 is provided with an annular and band-shaped upper cam 5, intermediate cam 6, and lower cam 7. These cams are provided with an upper cam track 5a, an intermediate cam track 6a, and a lower cam track 7a, each of which has a U-shaped groove extending in the circumferential direction and bending in the vertical direction, as shown in a development view in FIG. ing.

A ring gear 8 is mounted on the upper part of the lower cam 7.

Spindle-head assembly for roll-on cap 2
Is engaged with the cam followers 9a and 9b fitted to the upper cam track 5a and the lower cam track 7a and the ring gear 8, and covers the roll-on spindle 9 having the gear 9c for rotating the lower part and the roll-on cap on the bottle mouth. Consists of a capping head 10. The crown spindle-head assembly 3 also includes a stopper spindle 11 having a cam follower 11a fitted to the intermediate cam track 6a and a stopper head 12 for applying a crown to a bottle opening.

In the drawing, reference numeral 13 denotes a roll-on roller for threading a screw portion on the outer periphery of the roll-on cap, reference numeral 14 denotes a seal roller for winding the lower end of the roll-on cap into the bottle mouth, and reference numeral 15 denotes a spring.

In order to attach the roll-on cap to the bottle mouth using the above capping machine, first, the spindle-head assembly 2 for the roll-on cap is set. Next, the bottle covered with a roll-on cap by a cap release (not shown) is sent below the capping head 10, and when the apparatus is driven, the capping head 10 moves up and down along the lower cam track 7a, rotates and rolls on. Cap is roll-on roller 13 and seal roller
Attach the cap to the bottle mouth with 14.

The number of rotations by which the capping head 10 rotates while pressing the roll-on cap is determined by the length of a portion located below the lower cam track 7a. The length of the portion located below the lower cam track 7a is determined so that the capping head 10 rotates about 1.65 while pressing the cap.

In addition, when a crown is applied, the pressing force is large, so if the pressing time is long, the number of spindles located below the cam track increases, and an excessive load is applied to the turret, so that the pressing is performed. The shape of the intermediate cam track 6a is set so that the time is extremely short.

[Problems to be solved by the invention]

However, in order to close the mouth of a bottle or the like, a pre-screw cap made of synthetic resin or the like is used in addition to the roll-on cap, the crown, and the lip cap.

To screw the pre-screw cap, place the bottle with the cap under the capping head,
It is sufficient to press and rotate, the mounting operation is similar to that of the roll-on cap, but in the roll-on cap, the head 10 is rotated about 1.65 while pressing the cap, whereas in the pre-screw cap, , About two rotations of the head are required.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a capping machine that can attach a metal cap or a crown to a bottle mouth and can completely screw a pre-screw cap.

[Means for solving the problem]

In order to achieve the above object, in the capping machine according to the present invention, a second intermediate cam track is provided on the intermediate cam along the intermediate cam track, and a capping head for screwing a pre-screw cap to the bottle mouth is attached. The problem-solving means is that a roll-on spindle having a cam follower fitted to the second intermediate cam track is replaceably provided.

〔Example〕

1 to 3 show an embodiment of the present invention.

In these figures, the same elements as those shown in FIGS. 3 and 4 are denoted by the same reference numerals, and description thereof will be omitted.

The capping machine shown in FIG. 1 is different from the capping machine shown in FIG. 4 in that a second intermediate cam track 21 is formed along a cam track 6a of the intermediate cam 6, and a spindle-head for a pre-screw cap is further provided. Assembly 22 is installed.

The second intermediate cam track 21 has a lower part 21
The length a is long, and the number of rotations of pressing and rotating the pre-screw cap 23 by the spindle-head assembly 22 is increased.

Also, the spindle-head assembly 22 for the pre-screw cap includes a cam follower 24a fitted to the second intermediate cam track 21 and a roll-on spindle 24 having a gear 24c that meshes with the ring gear 8 and rotates the lower portion 24b. And a capping head 25 attached to the lower end.

In order to screw the pre-screw cap 23 with the capping machine, first, the spindle-head assembly 22 for screw cap is set. Next, the bottle covered with the cap 23 is set below the capping head 25 by a transport device (not shown). With the rotation of the turret 1, the cam follower 24a moves to the second intermediate cam track 21.
To be moved by the roll-on spindle 24
Is rotated by a gear 24c. When the cam follower 24a is guided to the lower portion 21a of the cam track 21, the rotating capping head 25 comes into contact with the top of the pre-screw cap 23 and rotates it, and the cap 23
Is screwed into the bottle. Since the second intermediate cam track 21 is formed so that the capping head 25 rises when the screwing is completely completed, the capping head 25
Leaves the cap 23 and the capped bottle is removed.

[Effect of the invention]

As described above, the capping machine according to the present invention is not only provided with a crown and a lip cap which are conventionally provided on the intermediate cam, but also with a pre-screw cap along the intermediate cam track. Since the second intermediate cam track is formed, the respective tracks of the upper cam, the intermediate cam, and the lower cam are selectively used, and the spindle-head assembly for the roll-on cap, the spindle-head assembly for the crown, and the spindle for the pre-screw cap are detachable. By replacing the head assembly,
It has the advantage of being compatible with any of roll-on caps, crowns, lip caps, and pre-screw caps.
