Description

[Detailed description of the invention] Many of the large empty boxes collected from consumers (sales offices, etc.) and sent to the expansion factory have artificial crowns.
It was necessary to uncork the empty bottles in the process before they were supplied to the additional line.

Conventionally, for collection bottles placed in shallow boxes, the neck of the bottle protruded from the top of the box, so it was possible to supply the product to a continuously rotating claw and continuously uncork the bottles while still in the box. In the case of Hosou, the head of the bottle was lower than the top of the box, so it was necessary to insert a claw from the top of the box intermittently, or to lift the box from the bottom into a stopped claw to open the bottle.

However, in this case, since it is a low-capacity intermittent operating machine, it is not suitable for actual production lines, and the current situation is that the plugs are uncorked manually.

The present invention has been proposed in order to eliminate the above-mentioned drawbacks of the conventional art, and aims to provide a corking machine that has a continuous high capacity for corkscrews as well as for shallow boxes, and has a sufficient uncorking force.

Further, 56 is a crown holder, and 57 is a crown guide.

The profile of the portion of the cam 45 corresponding to the plugging station shown in FIG. 6 has a radius portion indicated by R centered at point φ, and in this portion, the center line of the shaft 3 and the C-C cross section in FIG. The quadrilateral obtained by connecting the intersection φ3, the intersection φ26 between the center line of the shaft 26 and the CC cross section, the intersection φ44 between the center line of the cam follower 44 and the CC cross section, and the point φ is a parallelogram. It is supposed to form.

Further, 30a is the tip of the claw 30, 30b is the sloped surface of the claw 30, and 58 is a connecting shaft that connects the rotary disks 23 and 23a and transmits rotation.

The crown guide 57 is provided to scoop up the crown 59 held by the pair of claws 30, and the width of the portion that engages with the crown 59 is determined by the stopper 28 of the pair of claws 30. The spacing is smaller than the spacing between the tip portions 30a.

Next, to explain the operation, the bottle case 35 supplied to the roller 46 portion is filled with one bottle for every l cycle of uncorking.
stopper 2 via timing cam 19 in accordance with the movement of stopper 4.
1, the case 35 is indexed and sent one by one onto the sliding plate 47, and then the button shover 14 sends the case 35 to the uncorking station.

On the other hand, the rotational force of the driving motor 4 rotates the rotary disk 23 via the gear 5, the dog gear 6, and the rotating shaft 7, and at the same time as this rotation, the rotating disk 23a on the symmetric side is also rotated via the connecting shaft 58.

The orientation of the holder 25 etc. held on the shaft 26 by the rotation of the rotary disks 23, 23a is determined by the movement of the cam follower 44 fixed to the lever 43, that is, the cam profile of the cam 45, and as shown in FIG. It changes with respect to line φ3.

That is, quadrilaterals φ, φ3. In the range where φ26° to φ44 form a parallelogram, the case 35 and the holder 25 can be prevented from interfering by setting the cam profile of the cam 45 so that the holder 25 and the like are oriented in the direction of gravity.

The range of the parallelogram is the uncorking station, that is, from the position where the uncorking tool is inserted and lowered into the case to the position where the uncorking tool leaves the case. During this time, the uncorking tool moves vertically up and down, and the partition of the case , so as not to interfere with the outer frame, etc.

Thus, when the holder 25 hangs down from vertically above the bottle 42, the claw 30 is initially pressed against the stopper 28 by the leaf spring 33.
Since the distance between the tips 30a of the pair of claws 30 is smaller than the diameter of the crown 59 of the bottle 42, the inclined surface 30b of the claw 30 and the crown 59 of the bottle 42 engage, and the crown 59 As a result, the claw 30 is pushed open against the leaf spring 33.

When the tip 30a of the claw passes through the crown 59 of the bottle 42,
The pawl 30 is tightened again by the action of the leaf spring 33, and the pawl 3
The tip 30a of the bottle 42 is pushed down along the weir wall of the bottle 42.

That is, the guide 39 and roller 36 in FIG.
The tip portion 30a of the claw 30 obtains a force to be pushed down from the crown 59 portion of No. 2.

The tip 30a of the claw 30 is pushed down by the guide 39 to point P and then released from the guide 39.

At this time, the bottle shoulder press rubber 31 is displaced along the circumferential edge O while being pressed against the shoulder of the bottle.

- The tip 30a of the power water 30 is lifted along the line Q by engaging the roller 36 or the guide 41 with the point P as the lowest point.

Since the degree of rise of the line Q is selected to be larger than the displacement of the circumferential edge O, even if the claw 30a engages with the crown 59 of the bottle 42 and lifts the bottle 42 at the same time, the bottle shoulder of the bottle 42 and the bottle The engagement of the shoulder presser rubber 31 prevents the bottle 42 from lifting itself, the cap is removed, and the crown 59 is held by the magnet portion 32 of the claw 30.

Next, the claw 30, holder 25, etc. are lifted vertically to a position where they can be removed from the case 35, and the plugging process is completed.

The crown 59 is held by the claws 30 on the rotating discs 23, 23a.
The crown guide 57 engages with the crown guide 57 , peels off the claw 30 , and collects the crown receiver 56 .

As explained in detail above, the fixed cam of the present invention is arranged so that the plug remover is oriented in the direction of gravity within the range of the plug remover station from the position where the plug remover is inserted and lowered into the case to the position where the plug remover is removed from the case. The end point is set to the same vector as the vector connecting the axis center of the lever and the center of the cam follower under the condition that the plug puller is oriented in the direction of gravity with the rotation center of the rotary disk as the starting point. The guide has a cam groove having a circular locus at the center and having the same radius as the radius of the circular locus drawn by the shaft, and the guide lowers the pawl relative to the bottle shoulder press member at the uncorking station, and is struck by the bottle. The second guide is located downstream of the first guide and lifts the crown relative to the bottle shoulder holding member to remove the crown. It is now possible to continuously uncork collection bottles containing legal liquid, for which there was no definitive method, and it can also be used as an uncorking machine for shallow boxes.

In addition, since it uses a rotary disk, it is capable of continuous operation and is a compact, high-performance machine.Furthermore, the bottle shoulder holding member and the claw each draw different trajectories using cams, so lifting of the bottle is inhibited and only the crown is removed. It is lifted by the claw and can be removed with high efficiency.

The present invention can be incorporated into a universal anchor for legal phases (an anchor for legal phases), and it is also possible to handle a wide variety of products with different arrangements by simply attaching and detaching the rotary disk with claws.
