The two cam tracks 42a and 42b correspond to two different types of capping operations, for example, a capping operation with a pre-screw cap (referred to as type A cap) and a pilfer proof cap (referred to as type B cap). It is formed as follows. That is, in this embodiment, in the case of the capping operation when the type A cap is mounted, the driven roller 52a of the spindle head 70 is accommodated and engaged in the first cam track 42a, and the type B cap is attached. In the case of the capping operation for mounting, the driven roller 52b of the spindle head 70 is accommodated and engaged with the second cam track 42b and moved along the groove of the cam track.

(Rotation prevention member)
Furthermore, the capping device 1 is fixed to the lower surface of the fixed support plate 30 by a connecting member (not shown) at a position where the capping device 1 is substantially in close contact with the slider 51 between the third cylindrical rotary shaft 33 and each slider 51. And a rotation preventing member 43 that is partly in contact with the cam block surface and is detachably attached to the slider 51 to prevent the slider 51 from rotating.

FIG. It is AA cross-sectional view of the vicinity. As shown in FIG. 4, the rotation preventing member 43 is screwed to the slider 51 with bolts 45, the curvatures of the surfaces M1 and M2 at both ends substantially coincide with the curvature of the outer peripheral surface 40M of the cam block 40, and both ends It is preferable that the surfaces M1 and M2 are adjusted so as to be in contact with the outer peripheral surface 40M of the cam block 40. Thereby, even if the rotating member 54 of the capping head CH and the spinning head 70 rotates (autorotates), the slider 51 can be prevented from rotating accordingly.

  The screw hole 44 for tightening the bolt 45 has two directions (180 degree reversal) of the type A cap driven roller 52a side (44a) and the type B cap driven roller 52b side (44b). When the type of capping operation is changed, the anti-rotation member 43 fixed to the cam floor 51 is removed, the spinning head 70 is rotated 180 degrees, and the sealing head SH or capping head CH is used. Exchange. Since the slider 51 is also rotated with the rotation of the spinning head 70 by 180 degrees, the rotation preventing member 43 is screwed to the cam follower 51 with the driven roller being accommodated in the corresponding cam track and engaged. Any type of capping operation can be performed using the driven roller 52 and the cam track 42 corresponding to a desired type of capping operation.

  Thus, the capping device using the rotation exchange type spinning head of the present invention can be easily exchanged by rotating the capping head CH and the sealing head SH which are detachably attached to the spinning head 180 degrees, and the slider 51. By removing the anti-rotation member 43 and rotating the slider 51 180 degrees and then reattaching the anti-rotation member 43 to the cam follower 51, different types of capping operations can be performed with simple resetting.

Details of the capping operation are not necessary for the understanding of the present invention, so they are omitted, and only the main points are described.
During the capping operation, the rotation support plate 22 rotates with the container B placed by the carrying-in rotation turret 3 placed thereon, whereby the first cylindrical rotation shaft 20, the rotation support plate 22, the driven gear 23, 1 driving gear 24, rotating body 25, second cylindrical rotating shaft 26, mounting plate 27, sleeve 28, cylindrical bearing 29, and spinning head 70 and capping head CH (or sealing head SH) mounted thereon. Are rotated (revolved) around the central column 10 as a unit.
With this rotation, the type A cap driven roller 52a or the type B cap driven roller 52b slides while being accommodated in the first cam track 42a or the second cam track 42b of the cam block 40. As a result, the capping operation is performed sequentially.
Accordingly, by rotating the second drive gear 31 at a predetermined rotational speed, the rotation is driven by the driven gear 32, the third cylindrical rotating shaft 33, the third drive gear 34, and the rotating member. Accordingly, the rotating member 54, that is, the capping head CH (or the sealing head SH) attached to the attachment flange of the rotating member 54 is rotated at a necessary rotational speed. be able to.

  As described above, according to the capping device of the present invention, it is possible to perform a plurality of types of capping operations with different operating conditions by rotating the cam follower 180 degrees without exchanging the spinning head.

The above is merely an embodiment for explaining the present invention. Accordingly, it is easy for those skilled in the art to make various changes, modifications, or additions to the above-described embodiments in accordance with the technical idea or principle of the present invention.
For example, in the above-described embodiment, the number of cam tracks in the cam block 40 is two. However, for example, the number of cam tracks is increased to three, four, etc., and capping with three or more different operating states is performed. It is also possible to realize a capping device corresponding to the operation. In this case, the number of mounting holes of the driven roller 52 and the rotation preventing member 43 should be increased while changing the circumferential interval between the mounting holes of the driven roller 52 and the rotation preventing member 43 to 120 ° and 90 °. That's fine. Moreover, what is necessary is just to change suitably the drive rotation speed of the 2nd drive gear 31 with the kind of capping operation | movement.

  In the above-described embodiment, the rotation preventing member 43 having a shape as shown in FIG. 4 is used. However, the rotation of the slider 51 can be prevented so that the driven roller 52 of the slider 51 is properly guided to the cam track 42. As long as it is a thing, a rotation prevention member may be what kind of form.

It is the top view which showed the outline of the structure of the capping system provided with the capping apparatus of this invention along the rotation turret. It is XX longitudinal cross-sectional view along the plane which passes along the central axis of the spinning head in the symmetrical position with respect to the center of the capping apparatus shown in FIG. FIG. 3 is a development view showing an example of a cam track corresponding to two types of capping operations provided in the cam block shown in FIGS. 1 and 2. It is an AA transverse cross section near slider 51 of Drawing 2 showing an example of a rotation prevention member.
