Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention continuously and automatically removes crowns from bottle containers that are taller than the case peripheral wall and are conveyed by a roller conveyor or the like while being housed in a case. Regarding the uncorking machine that removes the cap.

[Technical background of the invention]

The contents are provided for consumer demand, and empty bottle containers such as beer bottles and soft drink bottles are collected for refilling. The collected empty bottles are then transported to the bottling factory in a case, but in this case, many of the collected bottles have their crowns artificially fixed, and they remain in this state. Since it is not possible to clean the inside of the bottle, the crown must be removed beforehand.

For this reason, in the past, the pair of claws were lowered to the crown lip while holding the bottle container so that it would not lift up from the case, and then the crown was removed from the top of the bottle container by raising the claws. I was doing it.

However, with this method, not only does it require a large amount of power to uncork the cap, but the opening of the bottle container may be chipped when the cap is uncorked, or the operation stop region may occur at the top dead center or bottom dead center of the vertical movement of the claw body. This made it impossible to work continuously and efficiently.

For this purpose, a corkscrew is first provided around the rotating body, and the contact and difference between the circular motion locus of the corkscrew and the linear motion locus of the top of the bottle container is utilized to efficiently remove the cap from the top of the bottle container. An uncorking machine is being considered that can remove the crown from the bottle. This capper remover is equipped with a synchronized disk or an indexing guide plate that rotates integrally with a rotating body provided with a capper remover so that the rotating capper remover matches the top of a conveyed bottle container.

However, the above-mentioned tuning disk or indexing guide plate, etc. performs tuning by engaging with the leading end and trailing end (horizontal crosspiece) of the case that houses the bottle container. If the case itself is short, the case's horizontal bars will not engage with the synchronizing disk or the indexing guide plate, and the uncorking tool will not reliably match the top of the bottle, making it impossible to uncork the bottle.

In addition, with conventional corking machines, even when transporting a group of bottle containers without crowns attached, such as new bottles, to a bottling factory, the corking machine is usually built into the line, so it is difficult to uncork them. I am trying to pass through the machine part. Even in this case, since the rotary body equipped with the capper is rotated as the bottle container is transported, there is a problem in that resistance is created during transport and the transport cannot be carried out smoothly.

[Purpose of the invention]

The present invention takes the above-mentioned points into consideration, and is suitable for cases where the case for accommodating the bottle container is short and it is not possible to perform synchronization by engaging the tuning disk with the leading and trailing ends of the case as in the conventional case. Also, make sure that the capper is aligned with the top of the bottle container to ensure synchronization, and when transporting new bottles that are not mixed with bottles with their crowns fixed, It is an object of the present invention to provide a capping machine that can smoothly transport bottle containers without engaging the bottle container with a rotating body provided with a capping section.

[Summary of the invention]

In order to achieve the above-mentioned object, the capper removal machine according to the present invention is provided with a rotating body equipped with a cap removal part disposed above a conveyor that conveys bottle containers that are taller than the peripheral wall of the case. The crown fixed to the top of the bottle is latched to the cork removal part in the area where the circular motion locus of the cork removal part contacts the linear motion locus of the top of the bottle container, and the crown is removed using the difference between the two trajectories. A tuning device whose outer periphery has a concave portion that engages with the body of a bottle container housed in a case is disposed on the upstream side of the rotating body, and the rotation of the tuning device and the rotating body are controlled. The gist is that the rotation is synchronized, and the shaft on which the rotating body is attached is installed between swingable arms, and a lifting member is provided at the tip of the arm to lift the tip. The main point is that it has been established.

The circumferential speed of the rotating body 45 is set to be equal to the circumferential speed of the rotating body 45.

Next, the operation of the corking machine will be explained.

First, a short case 1 containing a bottle container 18
7 is continuously placed on the roller 14 and the endless belt 15
make it run. Then, the roller 14 rotates and the case 17 is conveyed to the right in FIG. The body of the bottle container 18 housed in the outermost row of the case 17 to be transported, which projects above the case peripheral wall, fits into the recess 24a of the star wheel 24. Then,
The star wheel 24 rotates as the bottle container 18 moves, and this rotation causes the shaft 23, bevel gears 25, 28,
The rotation is transmitted to the shaft 36 through transmission mechanisms such as the sprockets 29, 32, 33, 42, etc., and the rotating body 45 rotates so that its circumferential speed becomes equal to the circumferential speed of the star wheel 24. There may be cases where a bottle is not contained in a part of the case 17, but in this case, the auxiliary synchronized roller 61 rotates as the case 17 moves, thereby causing the shaft 23 to rotate.

The cork removal parts 46 formed on the outer periphery of the rotating body 45 are spaced at intervals equal to the intervals between the bottle containers 18 housed in the case 17, and the cork removal parts 46 are
Since the circular motion locus of the bottle 18 and the linear motion locus of the top of the bottle container 18 partially contact each other, the bottle is uncorked by the action shown in FIG.

That is, at the point in time when the top of the bottle container 18 starts the contact area between the circular motion trajectory and the linear motion trajectory, as shown in FIG.
As shown in FIG.
engages with the lip of the When the bottle container 18 moves to the middle of the contact area, the crown 19 completely enters into the recess 47 of the capper 46, as shown in FIG. 4b. Furthermore, at the end of the contact area, as shown in FIG. Pull the lip part and remove it upwards. Then, the removed crown 19 is attracted to a magnet (not shown) provided in the recess 47 of the plug removal part 46, and rotates together with the rotating body 45 while being held in the recess 47.

Then, when the crown 19 held in the recess 47 rotates together with the rotating body 45 and the plug removal part 46 reaches the position of the release mechanism 52, the release member 4 of the plug removal part 46
The arm portion 49a of 9 is the roller 54 of the release mechanism 52.
comes into contact with. Therefore, the release member 49 rotates against the spring 50, and this rotation releases the recess 4.
The crown 19 held in the container 7 is knocked off and falls into the tray 55.

In addition, when all the bottle containers 18 housed in the case 17 do not have their crowns fixed, such as new bottles, it is not only wasteful to insert the tops of the bottle containers into the cap removal part 46, but also causes problems in the case. 17 may not be carried out smoothly. Therefore, in such a case, the lever 4 of the elevating member 38
Turn 0 upwards. Then, the rotator 39 rotates counterclockwise in FIG. 1 via the roller 41, and the rollers 41, 41 are positioned on the upper frame 12. As a result, the arms 35, 35 swing in the counterclockwise direction in FIG. The top of the container no longer comes into contact with the linear motion locus, the top of the bottle container 18 and the stopper 46 no longer engage with each other, and the bottle container 18 can be transported without resistance.

Note that instead of the star wheel 24, it is also possible to use an endless running guide such as a chain having guide vanes that engage between the pitches of the bottles.

〔Effect of the invention〕

As described above, according to the present invention, the capper remover removes the crown fixed to the top of the bottle container housed in the case to be transported, using the capper provided on the outer periphery of the rotating body. In this system, the synchronization between the transported bottle and the capper is achieved by engaging the body of the bottle, so even when the bottle is stored in a short case, it can be reliably synchronized. The crown can be removed continuously and efficiently, and when the crown is not attached to all the bottles, such as new bottles, the lifting member can be operated. Since the bottle container can be transported without contact between the capper part and the top of the bottle container, there are many advantages such as smoother transport.
