Description

[Detailed Description of the Invention] The present invention relates to a container filling and closing device that combines a rotary filling machine and a closure device such as a screw cap cap into a single unit.

Conventionally, for this type of filling and sealing equipment, the line configuration is generally tailored to the equipment with the minimum processing capacity. Because it is necessary to install a seaming machine in each container holder, the pitch of the container holder must be larger than a certain value.
For this reason, the pitch of the container holding part on the rotary filling machine side is
Even if it could be made smaller from the point of view of filling capacity, it was customary to match the pitch of the container holding part of the screw cap cap.

This invention was developed in order to utilize the high capacity of the filling machine when the pitch of the container holding part of the sealing machine is larger than the capacity of the rotary filling machine. A plurality of sealing machines are arranged so as to be in contact with the star foil on the discharge side, and the pitch of the container holding part of the rotary filling machine and the star foil on the discharge side is set to the pitch of the container holding part of the sealing machine. A small pitch corresponding to the reciprocal of the number of containers is used, and between this discharge side star foil and each sealing machine, the containers transferred by the discharge side star foil are sequentially transferred to each of the above sealing machines. It is characterized by the installation of a sorting device that divides the food into equal parts.

To explain the illustrated embodiment below, 1 is a supply conveyor, 2 is a rotary filling machine, and the supply conveyor 1
Container C transported by timing screw 3,
It is sequentially fed into the container holding section of the filling machine 2 via the supply side star foil 4. 5 is a star foil on the discharge side that receives the container C after filling, 6 and 7 are threaded caps disposed in contact with the star foil 5 on the discharge side, and both caps 6 and 7 are star foils on the discharge side, respectively. It is equipped with wheels 8, 8 and discharge conveyors 9, 9.

Pitch a of the container holding part of the screw cap caps 6 and 7
is set larger than a normal capping machine etc. due to the presence of a sealing machine (not shown) or other factors.
The pitch b of the container holder on the side is set to half the pitch a of the container holder, so that it is possible to transport containers equal to the sum of the processing capacities of the screw caps 6 and 7.

The sorting device for distributing containers to the two screw cap caps 6 and 7 includes a vacuum suction passage 10 opened every other container holding part of the discharge side star foil 5;
It consists of a gripping device 11 provided on the container holding portion of the screw cap 6 on the upstream side, and a fixed guide 12 provided on the screw cap 7 on the downstream side. Note that 13 and 14 are other fixed guides, respectively.

In this device having the above configuration, each rotary driving part rotates synchronously, and empty containers C are sequentially fed from the timing screw 3 and the supply side star foil 4 to the container holding part of the filling machine 2, and a well-known filling mechanism is used. The container C is filled while it is rotating. The filled containers are then transferred to each container holding portion of the discharge side star foil 5, and from these container holding portions are further distributed and supplied to two screw caps 6 and 7 by the above-mentioned distribution device. That is, each container C held by the discharge star foil 5 first interferes with the screw cap cap 6 on the upstream side, but the screw caps arranged at a pitch a twice the pitch b of the container holding part of the discharge star foil 5 interfere with each other. The gripping device 11 of the capper 6 holds the star foil 5 on the discharge side.
The remaining containers are held by the discharge side star foil 5 by the suction negative pressure of the vacuum suction passage 10 and reach the downstream screw cap 7, where they are attached to the fixed guide 12. It is then transferred to the container holding portion of the screw cap 7. The double-screw caps 6, 7 tighten the cap around the rotating container C, and the thus sealed container C is sent out via the discharge star foils 8, 8 and the discharge conveyors 9, 9. Although not shown, each container holding portion of the screw cap 7 on the downstream side is provided with a gripping device for preventing rotation of the container, similar to the screw cap 6 on the upstream side. Of course, such a gripping device is not necessary when a capping machine is used as the sealing machine, and the container can be capped by simply feeding the container into the container holder using the fixed guide 12.

In addition to the illustrated example, the container sorting device can also be obtained with the following configuration, for example. The first example is
A push-out body that can move forward and backward in the radial direction is provided between each gripping device 11 of the upstream screw cap cap 6 to eliminate the vacuum suction passage 10, and the push-out body and the container of the discharge star foil 5 are made to interfere with each other, so that the screw This prevents containers to be supplied to the stopper cap 7 from being transferred to the screw cap 6. Also, as a variation of this,
It is also possible to arrange an eccentric cam between each gripping device 11 and rotate it synchronously to press the container against the discharge star foil. In the second example, instead of the gripping device of the upstream sealing machine, a star foil 5 on the discharge side is used.
A vacuum suction passage similar to the vacuum suction passage 10 is provided. This example is particularly applicable when a capping machine is used as the sealing machine.

The present invention can also be applied in the same way in the case where three or more sealing machines are installed in contact with the star foil on the discharge side. That is, in this case, depending on the number of sealing machines installed and the pitch of their container holding parts, the pitch of the container holding parts of the filling machine and the discharge side star foil may be made small, and furthermore, a sorting device may be added. Furthermore, as described above, it is clear that the present invention can be applied to cases where a capper or capping machine other than a screw capper is used as the capping machine.

As mentioned above, the filling and sealing device of the present invention can be used when the processing capacity of the filling machine is higher than that of the sealing machine alone.
This has the effect of making it possible to perform highly efficient work by utilizing the processing capacity of the filling machine.
