Description

TECHNICAL FIELD The present invention relates to a capper that caps a cap on the mouth of a container.

"Prior Art" Generally, a capper has a clamp mechanism for gripping a container,
A capping head that caps the supplied cap on the mouth of the container and a cap supply mechanism that supplies the cap to the capping head are further provided.

The capping head grips the supplied cap in a state in which the cap is directed downward by a chuck mechanism, a negative pressure, or the like, and caps the cap from above in a mouth provided at the top of the container.

[Problems to be Solved by the Invention] As described above, in the conventional capper, the cap is capped at the mouth facing upward, and the cap facing the mouth facing downward can be capped. There was no.

By the way, when capping each mouth after filling a container having upper and lower mouths with a filling liquid, first, the upper mouth is opened while the lower mouth is sealed, and the upper mouth is opened in this state. After capping the mouth, open the mouth below. In this case, since the upper mouth is sealed, the filling liquid does not flow out of the container. Then, in this state, it is conceivable to rotate the container from the upright state to the upright state so that the lower mouth portion is directed upward and the cap is capped from above.

However, in such a case, there is a risk that the filling liquid inside the container leaks when the container is inverted.

"Means for Solving the Problem" In view of such circumstances, the present invention provides a capper capable of capping a lower mouth part of a container having an upper mouth part and a lower mouth part. Is.

That is, the present invention is provided with a tubular body portion, an upper mouth portion provided above the body portion, and a lower mouth portion provided below the body portion and having a smaller diameter than the body portion, and the upper mouth portion. When the container is closed, the container that conveys the filling liquid that is difficult to flow out is conveyed with the lower mouth portion facing downward, and the upper mouth portion of the container that is conveyed by the conveying means is sealed. A sealing means for preventing the filling liquid in the container from flowing out from the lower mouth portion, and a clamp mechanism for holding the container which has been conveyed to a predetermined position by the conveying means,
A capping head that raises the cap from below the lower mouth of the container held by the clamp mechanism to cap the cap on the lower mouth, and a cap supply mechanism that sequentially supplies the cap to the capping head. It is provided.

[Operation] According to the above configuration, the cap can be capped from below without inversion of the container, so that capping can be performed while preventing leakage of the filling liquid due to inversion of the container.

[Examples] The present invention will be described below with reference to the illustrated examples. In Figs. 1 to 4, a cylindrical container 1 has mouths 2 and 3 above and below its body (Fig. 4). ), The inside thereof is already filled with the filling liquid, and the cap 4 as the sealing means is capped on the upper opening 2 by a capper (not shown). Then, the four containers 1 are set as one set and are carried into the clamp mechanism 6 of the capper according to the present invention by the carrying means having an appropriate structure. At this time, the lower opening 3 of each container 1 is open, but the lower opening 3 has a smaller diameter than the body of the container 1 and the upper opening 2 is sealed, so The filling liquid in the container will not leak unless a relatively strong impact is applied to the container 1.

The clamp mechanism 6 includes four fixing plates 11 horizontally attached to the frame 10.
A circular table 12 (FIG. 1) is attached to the central portion of the container, and a hole 13 into which the lower opening 3 of the container 1 is inserted is formed in each fixing plate 11 and the table 12.

The clamp mechanism 6 is provided with a pair of clamp members 14 and 15 for holding two containers 1 each, and the pair of clamp members 14 and 15 are arranged in parallel with the fixed plate 11 to be mounted on the frame 10. It is slidably attached to the fixed guide rod 16.

Of the pair of clamp members 14 and 15, a movable frame 17 is attached to lower portions on both sides of one clamp member 14, and the movable frame 17 is extended to a position below the other clamp member 15 to the frame 10. Fixed cylinder device
By interlocking with the cylinder device 18, the clamp device 14 can be moved forward and backward by the cylinder device 18.

Then, while fixing the rack 21 to the movable frame 17, the rack 22 is also fixed to the other clamp member 15,
Moreover, a pinion 23 is meshed between the racks 21 and 22.
The rotary shaft 24 to which the pinion 23 is fixed is passed through an elongated hole 17a formed in the movable frame 17, and each end of the rotary shaft 24 is rotatably attached to a bracket 25 (FIG. 3) fixed to the frame 10. I support you.

Therefore, if one of the clamp members 14 is moved in one direction via the movable frame 17 by operating the cylinder device 18, the other rack 22 via the pinion 23 that meshes with the rack 21 moved in the same direction. And the clamp member 15 is moved in the opposite direction, so that the container 1 can be clamped and unclamped between the two by the mutual movement of the two clamp members 14, 15 in the opposite directions.

Next, a guide member 31 having a U-shaped cross-section (FIG. 2) whose lateral side is open orthogonal to the longitudinal direction of the four fixing plates 11 is fixed to the lower part of the four fixing plates 11.
A slider 32 is engaged therein so as to be movable back and forth. The slider 32 is supported by a guide rod 33 arranged in the longitudinal direction of the guide member 31 so as to be movable back and forth, and is reciprocally driven by a cylinder device (not shown).

In the slider 32, as shown in FIG. 1, the distance between the holes 13 formed in the fixed plate 11 is made equal, that is, 4
Pockets 35 for accommodating the caps 4 are formed so as to match the intervals of the book containers 1, and the caps 4 can be sequentially supplied from the chute 36 to the pockets 35.

At the tip of the chute 36, an air nozzle 37 and a stopper
When the slider 32 is moved to the left in FIG. 1, the stopper 38 releases the stop of the cap 4 and the air from the air nozzle 37 surely supplies the cap 4 into the pocket 35. On the other hand, when the slider 32 retreats, the stopper 38 stops the advance of the cap 4 so that the cap 4 is not supplied into the pocket 35.

Further, as shown in FIG. 2, the guide member 31 has
A through hole 41 is vertically formed at a position directly below the hole 13 formed in each fixed plate 11, and the through hole 41 is provided below the through hole 41.
Further, a capping head 42 that penetrates the hole 13 is provided. The capping head 42 includes a cylinder device 43.
Is raised and lowered by the capping head at the lower end position.
The upper end surface of 42 has substantially the same height as the lower surface of the slider 32, so that the cap 4 in the pocket 35 can be capped on the lower opening 3 when the upper end surface is located at the rising end position. .

In the above configuration, when the capping operation is started, the slider 32 is located at the right end of FIG. 1, and the inside of each pocket 35 is empty. The clamp members 14 and 15 of the clamp mechanism 6 are in an unclamped state in which they are separated from each other, and the capping head 42 is located at the lower end position.

In this state, one set of four containers 1 is transported by the transport means 5, and the lower surface thereof is paired with the pair of clamp members 14, 15.
Cylinder device of the clamp mechanism 6 when the lower mouth 3 is inserted into the hole 13 while being placed on the table 12 between
18 is activated to clamp each container 1.

In this state, the slider 32 is advanced to the left in FIG. 1 and the stopper 38 releases the stop of the cap 4, so that the cap 4 in the chute 36 is sequentially moved into the pocket 35 of the slider 32 by the air. Be accommodated. When the slider 32 reaches the forward end position and stops, the caps 4 housed in the pockets 35 are located on the capping heads 42 located at the lower end positions. Then, in this state, the cylinder device 43 is actuated and the capping heads 42 are raised, so that the caps 4 are raised and capped in the lower opening portion 3 of the container 1.

After that, when each capping head 42 is returned to the lower end position, the slider 32 is retracted to the right in FIG. 1, and at this time, the stopper 38 blocks the advance of the cap 4 and the pocket 35. The supply of the cap 4 into the inside is blocked.

In the above embodiment, the upper mouth 2 is sealed by the cap 4, but the conveying means 5 is provided with a sealing means as a sealing means, and the upper mouth 2 is sealed by the sealing means. The lower opening 3 may be sealed with the cap 4 and then the upper opening 2 may be opened to cap the upper opening 2.

[Advantages of the Invention] As described above, according to the present invention, it is possible to provide a capper capable of capping the lower mouth of a container having an upper mouth and a lower mouth. Moreover, at the time of capping, the cap can be capped from the lower side to the lower opening portion of the container as it is without inversion of the container, so capping can be performed while preventing leakage of the filling liquid due to inversion of the container. The effect is obtained.
