Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to the orientation and centering of a container when performing various treatments such as filling and tapping on a deformable container having an elliptical cross-section, for example. The present invention relates to a container holder which is used as a so-called “hammer” by inserting and inserting a container to obtain stool.

[Conventional technology]

Conventionally, a generally used container holder is usually one in which a container supporting hole adapted to a specific container shape is bored in a resin body, and therefore, this container holder is also used for different kinds of containers. It was difficult. For example, even if a plurality of container support holes are formed by crossing different container cross-sectional shapes on the body plane of the container holder,
The reality is that at most, it can be used as a dual-purpose container.

[Problems to be solved by the device]

As described above, the conventional container holder is difficult to be used for different kinds of containers, and it has the inconvenience of having to prepare various kinds of holders in advance, and moreover, between the above-mentioned bearing hole of the holder and the applicable container. Requires a clearance for fitting, the support of the container by the holder is loose.Therefore, when performing a processing operation such as filling or tapping the container with the holder, a container neck must be separately attached. It has the drawback of requiring a hold mechanism to hold it.

The present invention makes it possible to adapt to a wide variety of containers with a relatively simple structure, and minimizes rattling associated with the support state of the container by the holder. It is intended to provide an unnecessary container holder.

[Means for Solving the Problems]

In the present invention, in order to achieve the above object, a sealing gap is defined between a hard outer frame having a container supporting hole as a container holder and a wall of the container supporting hole. It is characterized in that it is provided with the attached diaphragm portion and valve means provided on the outer frame for guiding the supply and exhaust of air to and from the sealing gap.

[Action]

In the container holder according to the present invention, as described above, the container supporting hole provided in the hard outer frame is provided with the diaphragm portion that defines the sealing gap between the hole and the wall of the hole. Since the valve means for guiding the exhaust is provided in the outer frame, for example, in the air supply / exhaust section for supplying / discharging the compressed air provided in the supply path of the container, the compressed air is injected into the sealing gap through the valve means. However, the shape of the support hole of the diaphragm portion can be maintained in an accurate shape that matches the application container, or the diaphragm portion can be closely held to the outer periphery of the application container.

Therefore, no matter whether the former shaping function or the latter grip function is given to the diaphragm portion, the container is securely inserted into the holder at the time of processing the container and the container is securely attached without a neck gripper or the like. Can be held.

Also, for different types of containers, it is possible to apply some variation in container size by adjusting the resilience of the diaphragm part that originally exists or the pressure of air injected into the diaphragm part, but basically the outer frame is common. As a member to be used, only the diaphragm portion can be replaced with one having another container supporting hole shape at any time so that it can be easily adapted to various deformed containers.

The present invention will be described below with reference to illustrated embodiments. As shown in FIGS. 1 and 2, the holder (1) is composed of an outer frame (2) made of synthetic resin and a diaphragm part (3) made of soft synthetic resin or hard rubber mounted inside the outer frame (2). . The outer frame (1) is provided with a bearing hole (5) having a required margin for the cross-sectional shape of the applicable container (4), and is configured so that it can be commonly used for several kinds of containers. A centering bottom hole (5a) that can be engaged with a protrusion formed on the surface of a transfer conveyor (not shown) is provided at the center of the bottom. On the other hand, the diaphragm part (3) is formed with a bearing hole (6) adapted to a specific container, and is detachably mounted on the outer frame (2) via the restraining plate (7) and the screw (8). In addition,
(9) and (10) show seals provided between the diaphragm part (3) and the upper surface and the bottom hole (5a) of the outer frame (2). These seals (9) and (10) seal the seals. A sealing gap (11) is defined between the outer frame (2) and the support hole (6) of the diaphragm portion (3) by being stopped.

However, the outer frame (2) is provided with a valve means for pipe connection, that is, a socket with check valve (12) on one side in communication with the sealing gap (11). Pneumatic air supply / exhaust section (14) with multiple check valve plugs (13)

Therefore, the diaphragm part
(3) securely holds the container (4) in the holder (1) with a predetermined pressure,
The subsequent processing operations in the filling machine (16) and the stoppering machine (19) can be performed accurately and easily without the need for a neck gripper or the like. Then, in the container group with holder after the processing work is completed, the next compressed air supply / discharge section (14) is brought into contact with and separated from the socket (12) in the exhaust section indicated by the arrow (20) on the processing line.
When the plug and the plug (13) are engaged with each other, the exhaust from the above-mentioned sealing gap (11) is performed by connecting to the vacuum source or opening to the atmosphere. Then, these holder-equipped container groups in which the compressed air is discharged and the grip of the container (4) by the diaphragm part (3) is released, the holder (1) and the container (4) in the holder extractor (21).
The container (4) is sent to the next step as indicated by the solid arrow and the holder (1) is sent to the unscrambler (15) as indicated by the dotted arrow.

As described above, while the outer frame (2) of the holder (1) is a common member, the diaphragm portion (3) is formed as an attachment adapted to each container shape.
For example, it is performed as shown in FIG. In the figure,
(a) shows the container support hole shape of the diaphragm part (3) for a round container, (b) shows the case of a smaller diameter round container, (c) the flat container, and (d) the square container. Shown respectively.
In the case of the small diameter round container shown in FIG.
As shown in, a bottom plate (23) having a recessed portion adapted to the container diameter can be inserted on the bottom of the diaphragm portion (3) to help centering in the holder longitudinal direction.

Further, as shown in FIG. 5 (a), the support hole (6) of the diaphragm portion (3) may be provided with a curved portion (24) conforming to the container shape,
Alternatively, as shown in FIG. 3B, by providing a protrusion (25) having a V-shaped cross section, the center of the container can be surely performed.

As described above, in this embodiment, the pressurized gas supply / exhaust section is composed of the pressure section (17) and the exhaust section (20), which are arranged separately on the upstream side and the downstream side of the container processing apparatus, Container (4) in holder (1) between these two sections
However, depending on the level of flexibility of the container support hole portion of the diaphragm portion (3), only the shape-retaining function by supplying air to the diaphragm portion (3) may be added if necessary. There may be cases where it is sufficient to add.

In this case, the pressure section (17) and the exhaust section (20) described above do not need to be arranged as shown in FIG.
A holder (1) provided in the supply path as shown by the dotted line in the figure is provided as an air supply / exhaust section, and if a required number of the holder (1) group is inhaled, the holder is shaped by supplying the air.
(1) The group may be circulated and exhausted in the air supply / exhaust section after the work is completed.

Next, in the embodiment described above, the resin outer frame (2) of the holder (1)
Is used as a common member, and the inner diaphragm part (3) can be replaced with a plurality of types having different container support hole shapes so that it can be adapted to various types of containers. In the second embodiment shown in, the outer frame (2)
By providing a pair of pressure deforming members that are deformed by the supply of air such as bellows, and by deforming the shape of the container support hole of the diaphragm part (3) that inhales into this pressure deforming member and contacts it, It is designed so that it can be applied to containers. In other words, it can be said that this embodiment corresponds to the case where the shape retaining function of the diaphragm portion (3) is obtained.

That is, as shown in FIG. 6, in addition to the embodiment shown in FIGS. 1 and 2, in the longitudinal direction of the container supporting hole (6) of the diaphragm portion (3) so that it can be contacted from the inside. A pressure deformable member configured as the second diaphragm portions (26) and (26) is provided inside the outer frame (2) so as to face the above. A second check valve for connecting a pipe to the diaphragms (26) and (26) through a lateral passage (27) and a longitudinal passage (28) provided in the outer frame (2). Pressured air is supplied and discharged from the attached socket (29).

Therefore, in the case of this second embodiment, the socket (1

Further, the same action and effect as those of the holder of the first embodiment can be achieved by discharging the exhaust section (20) accordingly.

In the case of this second embodiment, when the compressed air is supplied and discharged from the socket (12) of the holder (1) to the sealing gap (11) between the outer frame (2) and the diaphragm portion (3). Since the sealing gap (11) is divided into the right side and the left side in the figure by the diaphragm portions (26) and (26) having a cylindrical shape, a communication passage for communicating the divided left and right gaps. It is desirable to drill, for example, in the bottom of the outer frame (2). Further, although the diaphragm portion (26) is provided as the compressible deformable member in the above-mentioned example, the same effect can be expected even if the diaphragm portion (26) is replaced with a bellows or piston structure.

Further, in the second embodiment, the diaphragm portion
Although a pair of diaphragm portions (26) and (26) are arranged as opposed to each other as pressure deformable members in the container support hole (6) of (3), the third diaphragm portion shown in FIGS. In the embodiment, the container holder in which the diaphragm portions are arranged separately in the horizontal direction and the vertical direction is shown.

That is, as shown in FIG. 8 and FIG.
In the container support hole (5) of (1), a sealing gap is formed between the hole and the wall of the hole.
A pair of diaphragm parts (30), (3
0) are laterally opposed to each other, and the both sealing gaps (11a), (11a) are communicated with each other through a bottom communication hole (31). Therefore, when pressurized air is supplied through the socket (12) of the holder (1), a pair of diaphragm parts (30),
A grip function or a shaped holding function of the container (4) can be added to the (30). Similarly, another pair of diaphragm parts (32), (32) are vertically opposed to the hole wall of the container support hole (5) through the closing gaps (11b), and both of these closing parts are closed. The gaps (11b), (11b) are communicated with each other through the lateral communication passageway (33), and the pair of longitudinal diaphragm portions (3
Also in 2) and (32), a pair of diaphragms in the above lateral direction.
The container (4) can be provided with a grip function or a shaped holding function in cooperation with (30) and (30).

Therefore, in the third embodiment, which can be said to be the separation type, it is possible to apply to a multi-type container by replacing only one of the vertical direction and the horizontal direction, or both of them. The vertical diaphragms (30) and (30) have a shaping retention function, and the vertical diaphragms (32) and (32) have a gripping function to support the container without rattling, or both the vertical and horizontal diaphragms are shaped. Various modes can be selected according to the application container, such as providing only the holding function.
