Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a container discharging device for discharging processed containers in a bottle washer or the like.

[Conventional technology]

In general, a container discharging device such as a bottle washer uses a discharging mechanism to discharge containers that have undergone processing such as washing in the machine onto a dead plate, and the containers on this dead plate are sequentially discharged one after another. It is pressed and moved by a subsequent container, pushed out onto a conveyor disposed adjacent to the dead plate, and discharged by this conveyor.

In such a container discharging device, while containers are being continuously discharged, the containers on the dead plate are successively pushed by the following containers and moved onto the conveyor; When there are no more containers left on the dead plate, the last container remaining on the dead plate is not moved onto the conveyor and cannot be carried out.

Therefore, a bottle discharging device equipped with a mechanism for discharging the last container left on the dead plate has already been proposed (Japanese Utility Model Publication No. 153495/1983).
The bottle ejection device disclosed in the above publication rotates an arm for pushing out bottles provided below the dead plate, and causes the tip of the arm to project upward from below the dead plate to push out the bottle from behind. It was hot.

[Problem that the invention attempts to solve]

In conventional container discharging devices such as those described above, in order to press the bottle by rotating the arm from the bottom to the top within a vertical plane, the bottle is rotated vertically relative to the upright bottle. Power is added,
The drawback was that the bottle could fall over.

The present invention has been made to eliminate such drawbacks, and an object of the present invention is to provide a container discharging device that can stably discharge containers left on a dead plate without overturning them.

[Means for solving problems]

In order to achieve the above object, in the present invention, a container discharged onto a dead plate by a discharge mechanism is pushed and moved by a subsequent container to be discharged, thereby pushing the container onto a conveyor. In a container discharging device for discharging containers, a horizontally rotatable lever is provided on the side of the container moving path on the dead plate, and this lever projects into the container discharging path to move the containers on the dead plate onto the conveyor. The container is characterized in that a driving means for rotationally driving the container is provided between a projecting operating position for pushing the container upward and a retracting position along the container transfer path.

[Effect]

In the present invention, by configuring the lever to rotate in the horizontal direction, the container can be moved onto the extrusion conveyor in a stable posture without applying vertical rotational force to the container that would easily cause the container to fall.

〔Example〕

Hereinafter, the present invention will be explained based on illustrated embodiments.

1 and 2 show a container discharging device for discharging containers after being processed in a bottle washer or the like, with FIG. 1 being a side view and FIG. 2 being a plan view of the main parts. Containers such as bottles that have been washed while being accommodated in a number of holders (not shown) and being continuously transported are released from the holders after being transported above the discharge mechanism 6 that includes a rotary cam 2 and a chute 4. , falls on the chute 4 due to its own weight and reaches the dead plate 8. Thereafter, the container B is pushed forward (to the right in FIGS. 1 and 2) on the dead plate 8 by the rotation of the rotary cam 2 in the direction of the arrow shown in the figure, and reaches the tip of the dead plate 8.

A conveyor 10 is disposed adjacent to the tip of the dead plate 8, and the containers B that have reached the tip of the dead plate 8 are
By the subsequent container which is subsequently discharged and pushed by the rotary cam 2 and advances on the dead plate 8,
It is pushed out onto the conveyor 10 and carried out of the bottle washing machine by this conveyor.

A plurality of the discharge mechanisms 6 as described above are usually arranged in parallel, and a plurality of containers are discharged simultaneously and moved on the dead plate 8. Therefore, the moving path 12 of each container is defined by the fixed guide 1 so that containers in multiple rows can move in parallel on the dead plate 8.
Each area is divided by 4. Each fixed guide 14 has a U-shaped side surface.
A lever 16 is housed within the space. This lever 16 is rotatably supported by the fixed guide 14 by a rotating shaft 20 provided near the tip of the dead plate 8. Each rotating shaft 20
is integrally formed with a shaft 22 extending vertically downward. Furthermore, pinions 24 are attached to the lower ends of the shafts 22, and these pinions 24 are connected to the conveyor 1.
It engages with a single rack 26 horizontally disposed below 0. Therefore, by causing this rack 26 to reciprocate, all the pinions 24 are rotated, and this rotation is transmitted to the lever 16 via the shaft 22, so that the lever 16 can be rotated. Note that the rack 26 is connected to the operating lever 28.
It is designed to be operated by. Further, as shown in FIG. 2, the tip 14a of the fixed guide 14 is directed toward the path 12 on the side where the lever 16 in the adjacent fixed guide 14 rotates among the container moving paths 12 on both sides. It is bent. To explain the operation of the container discharging device, when the bottle washer is operated and containers B are continuously discharged, the containers B on the dead plate 8 are disposed of by the following containers B.
Since the lever 16 is sequentially pushed out onto the conveyor 10 by the lever 16, the lever 16 does not need to be operated and is housed within the fixed guide 14. After the cleaning of container B is completed, the final container B is placed on the dead plate 8.
2, the rack 26 is moved upward in FIG. Then, each pinion 24 is rotated in the direction of the arrow shown in the figure, and in conjunction with this, the lever 16 is rotated from within the fixed guide 14 into the container moving path 12. This lever 1
By the horizontal rotation of the container 6, the containers B on the dead plate 8 are pushed out onto the conveyor 10 in a stable posture, and the discharge of all the containers B is completed.

In the above embodiment, the reciprocating movement of the rack 26 is performed by the actuating lever 28, but an air cylinder, a cam mechanism, or other actuating mechanism may be used instead. Furthermore, the timing of activation may be determined automatically by a signal from a cycle counter or the like, or by manual operation using a push button or the like. The discharging mechanism shown in FIG. 1 is based on a so-called rotary cam system, but it can also be applied to container discharging apparatuses using discharging mechanisms of various other configurations, such as a rotary chain bar system or a slowdown system. The rotation angle of the lever 16 is not limited to 90 degrees, but can be set as appropriate depending on the position of the rotating shaft 20 or the positional relationship with the conveyor 10. In addition, in the case of the conventional device, the arm passes through the slit in the dead plate, so its thickness is limited, but the lever 16 of the present invention can have any width depending on the shape of the fixed guide 14. By making the width wider, the contact surface with the container can be enlarged, allowing for more stable pressing.

[Effect of idea]

As described above, according to the present invention, a lever that rotates horizontally within the container movement path of the dead plate is provided to eject the last container left on the dead plate, which makes it possible to eject the containers that are last left on the dead plate. Unlike other devices, there is no risk of the container tipping over, and the container can be discharged in a stable state.
