Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a device for extracting a container from a holder for extracting a container from a holder.

``Prior art'' Conventionally, when the container to be filled is made of a soft material such as a soft synthetic resin or has a shape that makes it easy to tip over, it is necessary to prevent the container from tipping over and fill the container. In order to facilitate this process, the bottom of the container is fitted into a cup-shaped holder to hold the container.

In that case, it is necessary to eject the container from the holder, and conventionally, as a extraction device for extracting the container from the holder, the holder containing the container is transported in a straight line by a conveyor, and the upper part of the conveyor is A container gripping means disposed at the holder grips a container housed in the holder, and the container gripping means transports the gripped container horizontally at a constant height, while the container gripping means is disposed at the front end of the conveyor. It is known that the container and the holder are separated by guiding the holder diagonally downward by its own weight using a downwardly sloped inclined plate (Jikkosho).
47-6698).

``Problems to be Solved by the Invention'' However, in the conventional extracting device, the container was extracted from the holder while the holder and the container were in an upright position. In this case, there was a high risk that the container would fall over after being discharged from the holder, causing trouble.

In view of such circumstances, the present invention provides a device for extracting a container from a holder, which allows the container to be extracted from the holder while the container is in an overturned and stable state.

"Means for Solving the Problem" That is, the present invention provides a holder that has a holder holder that holds a holder, and that holds and transports a holder containing an upright container supplied from the outside with the holder holder. a conveyor, and a rotational drive means for rotating the holder holder conveyed by the holder conveyor from an upright state to an overturned state, thereby bringing the holder and container in an upright state into an overturned state;
a container extrusion device that is operated in synchronization with the holder conveyor and inserts a container extrusion member into a through hole formed at the bottom of the holder in an overturned state to extrude the container from within the holder; and a container extrusion device that is operated in synchronization with the holder conveyor. and a container transport conveyor that receives and transports the overturned container pushed out from the holder by the container pushing device.

"Function" According to the above configuration, the holder and the container accommodated therein are held in the holder holder in an upright state, and then the holder holder is rotated from the upright state to the overturned state by the rotation drive means. This allows the container to be overturned along with the holder. When the holder and the container are in an overturned state, the container pushing member of the container pushing device is inserted into the through hole formed at the bottom of the overturned holder, and the container is transferred from inside the holder to the container transport conveyor in the overturned state. It starts to push out.

Therefore, compared to conventional devices that take out the container in an unstable upright position, the container can be taken out from the holder in an inverted and stable state. Work can be carried out smoothly and reliably, with no room left over.

``Embodiment'' The present invention will be described below with reference to an illustrated embodiment. In FIG. 1, a rectangular holder 2 conveyed to the right by a conveyor 1 accommodates and holds the bottom of an upright container 3. This holder 2
and the container 3 are sequentially supplied into the holder holder 5 via the timing screw 4.

Each holder holder 5 is connected to a holder conveyor 6.
A large number of holder holders 5 are provided at predetermined intervals on the endless chain 7 constituting the holder 2, and as shown in FIGS.

It is housed and held within the bottom plate 5a, side plates 5b and 5c of.

Further, the fixed cam 11 moves the holder holder 5 to the second position from a position beyond the timing screw 4.
The holder 2 and the container 3 held by the holder holder 5 can be turned over from an upright position to a horizontal position.

Next, in FIG. 1, a container delivery device 15 is provided on one side of the holder transfer conveyor 6, and a container transfer conveyor 16 is provided on the other side. A container 3 is pushed out in a horizontal direction from a holder 2 in a holder 5, the pushed out container 3 is received by a container conveyor 16, and the container 3 is conveyed in an overturned state by this container conveyor 16. We are making it possible to do so.

As shown in FIG. 4, the container delivery device 15 includes a pair of left and right endless chains 17 disposed along the holder conveyor 6, and a pair of left and right endless chains 17 arranged at the same distance as the holder holder 5 between the two endless chains 17. It includes a cylindrical bracket 18 fixed in a direction perpendicular to the longitudinal direction of the endless chain 17, and a holder pushing member 19 is provided in each bracket 18 so as to be movable forward and backward.

Each of the holder push-out members 19 is fitted with a cam follower 21 that projects outward through a slit 20 formed in each bracket 18, and this cam follower 21 is engaged with a fixed cam 22 fixed to a machine frame (not shown). ing.

The fixed cam 22 can move the holder pushing member 19 forward and backward through the cam follower 21. As shown in FIGS. 1 and 2, the fixed cam 22 moves the holder pushing member 19
When protruding toward the holder holder 5 in an overturned state, the tip of the holder pushing member 19
It is possible to make the holder 2 pass through a through hole 5e formed in the bottom plate 5a and abut against the bottom of the holder 2, and move the holder 2 forward to a position where it abuts an engaging portion 5d provided on the holder holder 5. It's becoming like that.

Further, as shown in FIG. 5, a container pushing member 25 is provided in each of the holder pushing members 19 so as to be movable forward and backward, and a cam follower 26 attached to each container pushing member 25 is formed on the holder pushing member 19. slit 27 and the bracket 18
The cam follower 26 is caused to protrude outside through a slit 20 formed in the slit 20, and is engaged with a fixed cam 28 fixed to a machine frame (not shown).

This fixed cam 28 is also capable of moving the container pushing member 25 forward and backward through the cam follower 26, as shown in FIGS. 1 and 2.
The fixed cam 28 is configured to cause the container pushing member 25 to project toward the holder holder 5 side when the holder pushing member 19 projects toward the holder holder 5 side. This container pushing member 25 is attached to the holder 2.
It penetrates through a through hole 2a drilled in the container 3 and comes into contact with the bottom of the container 3, and the container 3 can be moved horizontally in an overturned state and pushed out onto the container conveyor 16.

The container conveyor 16 includes a pressing plate 30 that is provided at the same interval as the holder holder 5 and that engages with and advances the overturned containers 3 pushed out from the holder 2, and a pressing plate 30 that advances the containers 3 in the conveying direction. The container 3 is provided with fixed guides 31 that guide both sides, so that the container 3 can be transported to a downstream cartoner in an overturned state.

It is also possible to provide a cartoner instead of the container conveyor 16 and to directly accommodate the container pushed out from the holder holder 5 in a box supplied by the cartoner in an overturned state. Furthermore, when the height of the holder 2 is changed in order to be used for different types of containers, the fixed cam 22 that moves the holder pushing member 19 forward and backward can be adjusted accordingly, and similarly, the height of the container 3 can be adjusted accordingly. The width of the fixed guide 31 of the conveyor 16 can be adjusted.

Further, when the container 3 is pushed out from inside the holder 2, the holder pushing member 19 and the container pushing member 2
5 are returned to the retracted position by the fixed cams 22 and 28, respectively, and the holder holder 5 is returned to its original upright state by the fixed cam 11.
Then, as the holder holder 5 is rotated from the fallen state to the upright state, the holder 2 in the holder holder 5 moves under its own weight from the position where it abuts the engaging portion 5d to the bottom plate 5a of the holder holder 5. descend by

As shown in FIG. 2, the side plate 5b of the holder holder 5 has its lower part bulged and curved toward the container conveyor 16 so as to be separated from the holder 2, and is thereby held by the side plate 5b. A space 32 is formed between the holder 2 and the holder 2 . Then, when the holder holder 5 is returned to the upright state,
Of the pair of fixed guides 33 shown in FIGS. 1 and 2, one of the fixed guides 33 relatively enters the space 32 and guides both sides of the holder 2 in the transport direction with the pair of fixed guides 33. The pair of fixed guides 33 connect the holder 2 to the holder holder 5.
From then on, it is discharged onto the conveyor 34.
