Description

Description: TECHNICAL FIELD The present invention relates to a conveying device for a flanged container.

(Prior Art) At present, the food market such as desserts and beverages using a flanged container tends to be in a smaller quantity and a wider variety, and therefore it is desired to reduce the risk of time and cost associated with the shape change of the container. ing.

However, there has not been developed a transporting device that is capable of transporting a container by forming a sub-chamber for accommodating the container with a transporting device for a flanged container that is currently in practical use and shutting off the inside of the sub-chamber.

(Problems to be solved by the invention) As described above, as there is no transfer device that can form a sub-chamber for containing a container with a transfer device for a container with a flange and shut off the sub-chamber to transfer the container, aseptic filling is performed. There is a drawback that gas diffusion and filling of the drug solution in the sterilization part of the machine and sterilization and holding in the seal part cannot be maintained. Furthermore, the time and cost risks associated with changing the shape of the container cannot be reduced, and it takes time to change and repair the device due to the change in the shape of the container, and the cost increases due to the introduction of a new device. There are drawbacks.

(Means for Solving Problems) Therefore, the technical problem of the present invention is to prevent gas diffusion of a drug solution in the sterilization section of an aseptic filling machine and to maintain sterilization in the filling and sealing section, and the shape of the container. The purpose is to reduce the time and cost risks associated with the change and to miniaturize the chamber with the minimum space commensurate with the container size.
The technical means of the present invention for solving this technical problem is that guide rails that suspend and support both sides of a container flange are separated or brought close to each other by the rotation of a space adjusting rod, and the space is set to the diameter of the container. In a pushing device that is adjustable according to size and moves a container along a guide rail in a suspended state, the pushing device comprises a pushing plate standing upright in an endless belt, and the pushing plate is a filling machine chamber. As a partition plate for the inner transfer chamber, a sub-chamber that houses individual transfer containers together with the transfer chamber wall is formed, and it is possible to transfer containers with the sub-chamber shut off from the outside air. The device is adopted.

(Effects of the Invention) The present invention has the following effects as well as the effect that the shape or size of the flanged molded container can be easily dealt with in a short time. That is, desserts and beverage foods are currently being aseptically packaged, but with an aseptic filling machine corresponding to a molded container, it is difficult to partition in the filling machine chamber as compared with a sheet feeding type aseptic filling machine, and the medicine used for sterilization In the present invention, it is difficult to prevent the diffusion of the liquid and to maintain the sterility in the chamber.In the present invention, the container in the chamber is sub-chambered for each container by the pushing plate installed endlessly and the transfer chamber wall. Since it can be isolated with, when preventing the diffusion of air in the sub-chamber, the inside of the sub-chamber is made a negative pressure by exhausting, and the air is made to flow from the minute gap of the partition in the sub-chamber.
It is possible to prevent the diffusion of air from one sub chamber to another sub chamber.

In the case of maintaining sterility, on the contrary, laminar flow type sterile air is introduced from the top surface of the sub-chamber, and the inflow of air into the chamber can be prevented by positively increasing the pressure in the sub-chamber, In the aseptic filling machine, the gas diffusion prevention of the drug solution in the sterilization section and the filling and the sterilization retention in the sealing section, which are required, can be easily achieved.

(Example) The example shown in the drawings will be described below.

FIG. 1 is a principle view of suspension support of a flanged container and conveyance of the same in the present invention, and the rails for container support (1) (1) are arranged according to the container row to be transferred. The container (a) suspended by using the flange (a ') is attached to the chain (3) stretched between the sprocket wheels (8) and (8) with the pedestal (6) attached to the pushing plate (6). 4) Transferred along the rails (1) (1).

The drive shaft (5) of the sprocket wheel (8) (8) is driven by a prime mover (not shown), and the one shown in the figure conveys a pair of left and right chains (3) ( The pushing plate (4) is attached with the pedestal (6) between 3), and the container (a) is pushed by this.

Further, the rails (1), (1) are the rods (2) for adjusting the space,
(2) is screwed in, and the rod (2) for adjusting the space is
The interval between the rails (1) and (1) can be adjusted by simultaneously rotating (2) from outside the machine. This is the screw insertion part (7) (7 ') of the rail (1) with respect to the rod (2).
Since the screws are reversely threaded to each other, the distance between them is adjusted by moving the rods (2) closer to each other or away from each other, so that the lateral displacement of the container center due to the change in the distance does not occur.

It is desirable that the pushing plate (4) pushes the container (a) as close to the container flange (a ') as possible, that is, at a position close to the container suspension rails (1) (1).

2 and 3 show a filling machine to which the above-mentioned transfer device (A) is attached, and the transfer device (A) described above is incorporated in the filling machine chamber (20). As shown in FIG. 3, the pushing plate (4) forms a partition plate that forms a slight gap with the chamber side wall (20a), and a plurality of partition plates are erected at regular intervals in the chamber (3). . Guide rails (1) and (1) are arranged above the pushing plate (4), and the guide rails (1) and (1) are similar to those in FIG. ) Rotation adjusts the interval.

The containers (a) are dropped one by one from the container supply unit (9) onto the rails (1) and (1) in the filling machine chamber (20), and the dropped containers (a) are railed by their flanges (a '). (1)
Suspended and supported by (1) and transferred along rails (1) and (1) by a pushing plate (4) attached to a pedestal (6) on the chain (3) by driving a sprocket (8) (8). To be done.

The container (a) transferred along the rail (1) (1) is
It is housed in a sub-chamber (25) partitioned by front and rear pushing plates (4) and (4), and is transported together with a moving sub-chamber (25).

During the transportation, the container (a) is sterilized by the drug nozzle (10), and the drug is removed by the heated air from the next heated air pipe (14).

The container (a) from which the drug has been removed is a sterile air supply pipe (1
5) Dessert at the filling nozzle (11) in the filling nozzle chamber (28) of the chamber where aseptic air is supplied from
The beverage (food) is filled and the lid (b) is sealed by the sealing device (12). The container (a) with the lid material (b) sealed is mounted on the rail (1) (1) by the push-up rod (24).
Is pushed up and discharged.

In FIG. 2, (16) is an exhaust port, (17) is a first decompression chamber, and (18) and (19) are second and third decompression chambers. The other (13) is the top surface for subchamber partition.

FIG. 3 is a cross-sectional view of the filling portion in FIG. 2, in which the container (a) is suspended by a rail (1) into which cooling water (29) has been introduced, and a pushing plate (which is connected to a drive chain (3) ( At the time of transfer by 4), the side wall (20a) of the filling machine chamber (20) is formed by the pushing plate (4) and the sub chamber (25) is formed by the pushing plate (4), and the laminar flow type sterile air is supplied to the sterile air supply pipe ( 15) is supplied from the laminar flow air supply section (21) and is exhausted from the exhaust port (16) via the exhaust section (22). Here, the laminar air supply part (21) and the exhaust part (22) are formed by a punching board.

In Fig. 3, there is a large space (30) on the top surface, and it seems that the sub-chamber formation is insufficient.
It is functionally sufficient because the upward airflow is not generated by the laminar flow air and the filling portion itself is partitioned by the subchamber partition top surface (13) in FIG.

The decompression chambers (17), (18), and (19) for exhaust are located between the drive chains (3) to make the sub-chamber formation efficient.

The container (a) is supplied from the container supply unit (9) as described above, and is sterilized by the drug, removed by the drug, filled, sealed and discharged while the sub-chamber (25) is maintained.

Since the required strength of the air flow in the sub-chamber (25) in each part is different, the exhaust decompression chamber is divided into decompression chambers (17), (18) and (19), and the decompression degree is also different. Of course, the number of decompression chambers may be increased or decreased as necessary.

The heating air pipe chamber (27) and the filling nozzle chamber (28) are positive pressures, respectively, from the medicine nozzle chamber (26) and the heating air pipe chamber (27). The subchamber partition top surface (13) has a positive pressure from each room. This is to maintain sterility and prevent drug diffusion.

When the container (a) is changed, the rails (1) and (1) are adjusted to have an interval suitable for the container (a).

This operation can be performed aseptically because the adjusting rods (2) and (2) shown in FIG. 1 can be simultaneously rotated from the outside of the filling machine.

Further, even if the container size is changed, the function of the sub-chamber does not change because the pushing plate (4) is common.

An additional advantage of the present invention is that the device can be miniaturized. In the conventional filling machine chamber, which requires a large space, a chamber having a minimum space corresponding to the container size is sufficient, and the chamber is naturally downsized. In addition, the amount of air supply and exhaust for positive pressure or negative pressure container air is also reduced, which is advantageous in terms of energy saving.
