Therefore, due to the push/pull operation of the air cylinder devices 35, 36 that cantilever the retractable rods 33, 34, the opposing clamp bodies 40A, 40B of the chuck device 37 approach and separate from each other between the clamping position and the release position of the container (2). The clamp bodies 40A and 40B move back and forth between the container standby position P1 on the alignment conveyor 2 and the filling position P2 below the filling machine 13 by the push/pull operation of the air cylinder device 30 mounted on the guide receiving frame 19. (See Figures 9 and 10).

In this embodiment, as shown in FIG.
By arranging the clamp bodies 40A and 40B of each chuck device 37 on an imaginary line parallel to the discharge conveyor 3, the bush rollers 41A and 41B are configured to have longer lengths in order from the filling position P2. The containers V pushed out onto the discharge conveyor 3 are configured so that the containers V are pushed out more sequentially as the containers V are pushed out further toward the rear of the discharge conveyor 3 in the conveying direction.

The operation will be explained below.

The electric motor 11 with a variable speed reducer is operated continuously, and the entrance gate section 6
The supply conveyor 5 is operated so that there are always six or more containers ■.

When it is detected by a phototube device (not shown) that there are six or more containers (2) in the entrance gate section 6, the detection signal starts the electric motor 8 with a brake and variable reduction gear, and the alignment conveyor 2 is operated.

The star wheel 10 also starts rotating in synchronization with the alignment conveyor 2.

Container V of entrance gate part 6 by 100 revolutions of star foil
are sent one by one to the starting end of the alignment conveyor 2 at equal pitches.

The container V sent in first is at the waiting position P on the terminal side.
, a proximity switch (not shown) detects this,
The signal causes the electric motor 8 with a brake and variable reduction gear to stop, thereby stopping the operation of the alignment conveyor 2 and star wheel 10.

At this time, containers (3) are being sent to all the standby positions on the alignment conveyor 2, respectively.

The extrusion operation of the air cylinder device 30 is started in response to the alignment completion signal of the containers (■), and the chuck device 37 is opened as shown by the solid line in FIG.
It moves forward in one direction to the standby position of the container (■).

When the clamp bodies 40A, 40B are located on both sides of the container (2), the operation of the air cylinder device 30 is stopped, and then the air cylinder devices 35, 36 for opening and closing are pushed out, and the clamp bodies 40A, 40B are brought close to each other. 10
As shown by imaginary lines in the figure, the clamp bodies 40A, 40B
The container (■) located at the standby position P1 is held between the two.

When a limit switch (not shown) detects that the container (2) is clamped by the clamp bodies 40A, 40B, the air cylinder device 30 starts retracting operation based on the signal, and the chuck device 37 moves back via the movable table 20. [Fig. 10 arrow Z2].

By this backward movement, the container (2) slides on the transfer plate 18 as indicated by the arrow z1 in FIG. 10 and is transferred to the filling position P2.

It is confirmed that the container ■ has been transferred to the filling position P2 by the glue □
When detected by the switch, the filling machine main body 17 is lowered by the actuation of the air cylinder device 16, the spout pipe 17A is inserted into the mouth of the container (2), and filling begins.

At the same time as the filling machine main body 17 starts to descend, the alignment conveyor 2 is operated again, and during filling into the container
A subsequent container V is carried into the standby position P1.

Furthermore, in parallel with this, the clamping state of the container (2) between the clamp bodies 40A and 40B is released.

By the time the filling is completed, the chuck device 37 again moves forward Z1 to pick up the succeeding container (2) to its standby position P1.

After filling is completed, the filling machine main body 17 rises, and when it reaches its upper limit, a limit switch (not shown) detects this and causes the chuck device 37 to move back.

The chuck device 37 has already clamped the subsequent container V while the filling machine main body 17 is being raised.

Due to the double movement z2 of the chuck device 37, the filled container V is
Clamp arm 39A.

The bushing rollers 41A and 41B at the rear of the bushing 39B slide on the delivery plate 18 and are pushed onto the discharge conveyor 3 (arrow Z4 in FIG. 10).

At the same time, the subsequent container (2) is transferred to the filling position P2.

Thereafter, the above-described operation is repeated.

As shown in Fig. 11, filled containers (■) are pushed out more as they move toward the rear of the discharge conveyor 3 in the conveying direction.
When being discharged on the discharge conveyor 3, the container (2) does not interfere with the other bush rollers 41A, 41B.

This discharge is completed before the subsequent container V is pushed onto the discharge conveyor 3.

As is clear from the above-described embodiments, the present invention allows carrying a container from a standby position to a filling position and pushing out a filled container to a discharge conveyor at the same time when the chuck device returns. Moreover, since the containers are automatically carried into the standby position by the feeding device, the series of steps from supplying empty containers to discharging filled containers can be performed efficiently. Since the discharge conveyor, the filling machine, and the chuck device can be arranged neatly in a rectangular space in plan view, the installation space can be narrowed and the structure can be simplified.

Furthermore, as explained in the above embodiments, the series of steps can be controlled by simple control equipment mainly consisting of limit switches, so that the control device itself can be simplified.
