Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cap supplying device for supplying a cap to a capping applicator used, for example, in the production of a peroxide-filled film.

11ljK c) Capping of the o-neck body member is carried out by holding the cap in the cap holder in the applicator, and then moving this holder to fit and attach it to the cartridge body member already held in a fixed position. Therefore, it is necessary to reliably supply one cap '5 to the applicator in accordance with the operation of the applicator.

The present invention was made based on such a request, and it is an object of the present invention to provide a cap supplying device that has a simple configuration and can reliably supply caps to applicators addressed to 1fli with high reliability. This is the purpose.

The present invention is characterized by a cap transfer mechanism that transfers a large number of caps in line along a feeding path, and a pioneer cap located at the downstream end of the feeding path that is activated and then stopped. a first stopper for causing the first cap to stop, a second stopper for causing the top cap to be in an operating state and stopping the cap, and a drive mechanism for alternately bringing the 1lNl stopper and the M2 stopper to an operating state; The trailing cap is at the point where it is stopped by the front (8) metering stop after being released from said second stop.

The invention will now be described in detail with reference to the drawings.

Fig. 1 shows a device for supplying a cap holder to a cap holder constituting a capping applicator used for producing film containing cartridges, and in this embodiment, a large number of caps are lined up along the feeding path. In the cap transfer mechanism 1, for example, the inlet of the chute 11 placed in an inclined state is connected to the discharge port of the vibrating parts feeder, and the back plate near the lower end of the shoe 11 is 12, two through holes 8M and 8B are formed so as to be lined up in the travel direction, and one end thereof is inserted into the chute 11 through the downstream side through hole 8A, and is located at the downstream end of the transportation route. A first stopper 5m is provided which comes into contact with the lower end of the leading cap 4A to stop the running of the leading cap 4A, and further a trailing cap 4B following the leading cap 4A.
A second stopper 5 is inserted into the central circular hole 41B through the upstream through hole 8B to stop and hold the subsequent cap 4B.
B is provided, and these stoppers 5 s5B are alternately operated 1
ζ interday qss-22214 (2) state (state in which one end of each is pushed into shoe 11)
A driving machine @e is provided. This drive fh mechanism 6 includes, for example, a link 61 pivotally attached to each stopper 5A, 5B and g#4 so as to connect them, and a cap held by the cap holder 2 connected to the cartridge body member. It consists of an air cylinder 62 that is activated in accordance with the timing when it is fitted and installed. In the figure, 21 is an electromagnet for holding the cap in a predetermined position on the cap holder 2. Here, FIG. 2 shows an example of a capping applicator, and the applicator in this example is provided with a gate-shaped frame 28 on a rotation shaft 22 that is rotated around a rotation center X, and this frame 28 to the bridging rod 24 of
A cap holder 2 is provided which is rotated about a central axis Y of the holder 2, and when a cap is fed to this holder 2, the cap is held by the frame body 28 and the holder 2 being rotated in sequence. It is fitted and attached to the patrone chest member 26 held by a mechanism (not shown).

26.27 is determined by the operation command of each cam machine etc. (5) It is an operating rod that is activated.

In a cap feeding device having such a configuration, for example, the vibrating parts feeder is operated to transport the caps along the chute 11, and the first stopper 5A is moved to the tip of the first stopper 5A as shown by the solid line in FIG. In the state in which the head cap 4A is inserted into the shoe 11 from the through hole 8A, that is, in the operating state, the leading cap 4A located at the downstream end 1a of the feeding path is held by the first stopper 5A.
While stopping directly above 1a of A, the second stopper 5B
is kept inactive. In this state, the succeeding cap 4B is held and stopped at the upper end of the leading cap 4A, and the following caps are also stopped in the same way (each figure is an explanatory drawing, so there is a gap between the caps. )
. Then, the cap holder 2 is moved simultaneously, and the cap that was positioned in the holder 2 is removed from the cartridge body member 25.
When the air cylinder ti2 is fitted and installed and returned to its original position, the air cylinder ti2 is extended to operate the link 61, and the second stopper 5B is inserted into the through hole 8B as shown in [7] in FIG.
(8) The first stopper 5A is inserted into the chute 11, ie, in an operating state, and the first stopper 5A is pulled out from the through hole 8A toward the rear side of the chute 11, ie, in an inoperative state. As a result, the leading cap 4A, which had been stopped by the first stopper 5A, falls and hits the cap holder 2.
However, the trailing cap 4B, which was held by the leading cap 4A until the leading cap 4A starts to fall, has reached the circular hole formed in the center of the cap 4B by the second stopper 5B. 41B and is held by the second stopper 5B. Next, the link 61 is actuated by the retraction of the air cylinder 62, and as shown in FIG. 1M stopped by B
Cap 4Bit falls to the position of Ml stopper 5A and is stopped by this first stopper 5A,
The cap 4C right behind this is the 1ft mentioned above? It will be located where cap 4B was located (7). When the first cap 4A held in the cap holder 2 is consumed, the air cylinder 62 is released again and the first stopper 5A becomes inactive, and the caps are lined up in the feeding path in this way. One cap is supplied to the next cap holder 2.

mj In the above-described embodiment, the first cap 4A located at the downstream end of the feeding path is fed to the applicator by releasing the first stopper 5A, and when the first stopper 5A is released, the second stopper 5B is fed to the applicator. By stopping the succeeding cap 4B and activating the collars 5A and 5B alternately, the caps lined up in the feeding path are
Since the structure is such that each piece is sent out one after another, by using a continuous feeding device such as a vibrating parts feeder, it is possible to reliably feed each piece of cap to the applicator in accordance with the timing of capping performed by the applicator. Moreover, the part that separates the first cap from a large number of caps lined up in a row is the two stoppers 5A,
5B and a drive mechanism 6 that alternately puts them into operation, it can be constructed using a simple S structure. Furthermore, in this embodiment, in order to stop the cap 4B by the second stopper 5B, the second stopper 5B is not forcibly inserted between the leading cap 4A and the trailing cap 4B. Since the caps are inserted into the circular holes by using the circular holes in the sleeve, the flow of the caps can be reliably stopped without disturbing the rows of caps.

As described above, in the present invention, the first stopper 5A is set in the operating state to prevent the subsequent cap 4B from falling into the applicator when the second stopper 5B is set in the non-operating state. The time when the stopper 5A is brought into operation is not necessarily the same as the time when the second stopper 5B is brought into the non-operation state. kWtt
The first stopper 5A may be brought into operation before the cap 4B reaches the position of the first stopper 5A.

Note that the present invention is not limited to feeding the caps by tilting the feeding path and using gravity (9), but it is also possible to use a transfer mechanism so that the caps are constantly transferred toward the striped brim. Depending on the configuration, the feeding path can extend horizontally, or the cap can be fed along an inclined feeding path from below to above.

As described above, according to the present invention, it is possible to provide a cap supplying device that has a simple configuration and is capable of reliably supplying a cap to an applicator addressed to 1gi with excellent efficiency.
