Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a container discharging device, and more particularly to a container discharging device that continuously discharges containers processed by a container processing device such as a bottle washer.

Generally, in a container processing device such as a bottle washing machine, a basket conveyor holds and transports the container through the device, and the container is processed during this time. The containers processed in this manner are discharged and sent to the next process by a container discharging device that includes a discharge conveyor and a delivery member that delivers the containers to the discharge conveyor.
The shapes of containers processed by bottle washing machines etc. are not limited to circular shapes, but also include various deformed containers such as ellipses and squares, and in the case of a multipurpose machine that can be applied to these various deformed containers, the following process For processing, it is necessary to position and align the deformed containers in a certain direction, either during or after container ejection. If positioning is performed after discharge, a separate alignment device must be provided, and if discharged without positioning, the containers will mesh with each other on the discharge conveyor. There were drawbacks such as the so-called bridging phenomenon. Therefore, a discharge device has been proposed that aligns the deformable containers in a certain direction during discharge (for example, Japanese Utility Model Publication No. 57-52075). However, such a discharging device requires various members such as a bottle bottom guide that supports the bottom surface of the bottle, a bottle side guide that supports the side surface, and a transfer member that transfers the bottle to the discharge conveyor. By preparing a large number of shapes corresponding to the external shapes of various deformable containers and replacing them each time, it was possible to accommodate various deformable containers. Therefore, it has disadvantages in terms of both cost and efficiency.

The present invention was devised in view of the above-mentioned drawbacks, and the present invention is designed to improve the distance between the extrusion member that extrudes containers received from the basket conveyor onto the discharge conveyor and the guide member that supports the sides of the containers extruded onto the conveyor, and the movement of the extrusion member. The process is set according to the external shape of the deformable container to be discharged, and the distance between the front surface of the extrusion member at the forward end and the guide member is set approximately equal to the length of the short side of the deformable container, and the extrusion a first forward movement in which the member is advanced to a position where the distance between the end of the delivery member side of the discharge conveyor and the front surface of the extrusion member is smaller than the long side of the container and larger than the short side of the container; By performing forward drive in two stages, including the second forward movement in which the container is advanced to the end and transferred to the discharge conveyor, a separate member is not required, and the simple structure can accommodate various deformed containers. The present invention provides a container discharging device that can be used.

The present invention will be explained below based on the illustrated embodiments.
FIG. 1 is a front view showing an example of a container discharging device connected to an end of a bottle washer. Containers A washed by the bottle washer are stored in each basket 2 of a basket conveyor 1. At the same time, the bottom surface is guided by the bottom guide 3 and conveyed to the container discharging device. A bottle support plate 5 that swings about a shaft 4 is disposed at the end of the bottom guide 3 to support the container A that has passed through the bottom guide 3. A container delivery member 6 is provided below the bottle receiving plate 5 and is rotated about an axis (not shown) to move up and down.
When the plate 5 swings downward, it rotates after receiving the container A and lowers the container A to the same height as the upper surface of the discharge conveyor 7. The lowering container A is supported on its side by a warp guide 8 disposed along the movement locus of the delivery member 6. A container pushing member 9 that can move back and forth is provided behind the discharge conveyor 7 of the container delivery member 6 in the lowered position.
The container A on the delivery member 6 is transferred onto the discharge conveyor 7 by moving forward and backward in the direction of. The container A pushed onto the discharge conveyor 7 by the pushing member 9 is supported on its side by a conveyor guide 10 provided on the conveyor 7, and is stopped at a central position of the conveyor 7. Note that the container A is normally configured to discharge a plurality of rows of containers A at the same time, and a partitioning member 11 is fixed to the side of the discharge conveyor 7 to separate the containers A from each other. However, this partition member 11
may not be necessary depending on the shape of the container to which it is applied.

The container A can be removed by the container discharge device having the above configuration.
The state in which is discharged will be explained with reference to FIGS. 2a to 2d. As the plate 5 swings, the container A supported on the plate 5 via the bottom guide 3,
It moves onto the container delivery member 6, which has been raised to the vicinity of the lower surface of the plate 5. At this time, the delivery member 6 has already started descending to avoid interference with the plate 5 (see FIG. 2a). The container A that has completely transferred onto the transfer member 6 is gradually lowered while being guided by the warp guide 8 on its side (second
(See Figures b and c). After the transfer member 6 descends to position the bottom of the container A at the same height as the discharge conveyor 7, the container pushing member 9 operates to push the container A toward the conveyor (see Figure 2 d). .

Container A pushed out by container pushing member 9
The process of transferring the material onto the conveyor 7 will be explained in detail with reference to FIGS. The container discharging device according to the present invention is capable of discharging deformed containers whose bottom surfaces have long sides and short sides while arranging them. This is applied to bottles. The bottom surface B of the container A has a substantially rectangular shape with the length of the long side L being 1 and the length of the short side S being s. Discharge conveyor 7
The positional relationship between the conveyor guide 10 and the container pushing member 9 is set as follows. That is, the distance between the extrusion member 9 side end 7a of the conveyor 7 and the guide surface 10a of the conveyor guide 10 is as follows.
The distance between the end 7a of the conveyor 7 and the front surface 9a of the pushing member 9 is approximately equal to the short side S of the bottom surface B of the container, and is slightly larger than the long side L of the bottom surface B of the container. The container A is lowered by the container delivery member 6 between the conveyor 7 and the container pushing member 9 which are in the above positional relationship. At this time, since the orientation of containers A is not regulated, containers A are mixed in various orientations (see FIG. 3a). Then the container pushing member 9 is activated. This forward movement of the pushing member 9 is the first
The process is carried out in two stages: the first forward movement and the second forward movement after a temporary stop. The stop position in the first stroke is a point where the distance between the front surface 9a of the extrusion member 9 and the end 7a of the conveyor 7 is smaller than the long side L of the container bottom surface B and larger than the short side S. (See Figure 3 b). Therefore, when the long side L faces in a direction perpendicular to the direction of movement of the conveyor 7, a part B' of the bottom surface B of the container is placed on the conveyor 7, and as a result, the conveyor 7 is driven. Therefore, the portion B' placed on the conveyor 7 is swung in the direction of movement of the conveyor 7. Further, when the long side L faces in a direction parallel to the traveling direction of the conveyor 7, the entire bottom surface B of the container A is located on the delivery member 6 without being transferred onto the conveyor 7. Container A with part B' of bottom surface B on conveyor 7
The extrusion member 9, which had been stationary while being redirected by the conveyor 7, then performs a second forward stroke. The push-out member 9 is moved to a position substantially above the end 7a of the conveyor 7 by the second forward movement (see FIG. 3c). By this second forward movement, the container A whose long side L is parallel to the traveling direction of the conveyor 7 is transferred onto the conveyor 7 while facing the same direction. Container A, which is facing in a direction inclined to the direction of movement of the container A, is pushed by the extrusion member 9 on the rear side and regulated by the conveyor guide 10 on the front side, so that its direction is gradually changed and the container A is extended in length. It is completely transferred onto the conveyor 7 with the side L facing the direction of movement of the conveyor 7. In this way, the containers A whose long sides L are perpendicular to the direction of travel of the conveyor 7 are changed in direction, and all containers A have their long sides L parallel to or inclined to the direction of travel of the conveyor 7. After that, the containers A are transferred onto the conveyor 7 while being sandwiched between the extrusion member 9 and the conveyor guide 10, so that all the containers A can be aligned and discharged in the same direction. Thereafter, the pushing member 9 is moved back (see FIG. 3d) and returned to its original position (the position shown in FIG. 3a), after which the next container is lowered and the same operation is repeated to eject the container.

Note that during the second forward movement of the extrusion member 9 (the third
If the discharge conveyor 7 is temporarily stopped as shown in FIG. c), the containers A can be reliably transferred from the container delivery member 6 to the conveyor 7 in a stable posture.
It goes without saying that the container delivery member 6 is not limited to the above-mentioned structure, and that various conventionally known systems can be applied as long as it is related to a structure in which containers are delivered intermittently.

As described above, according to the present invention, it is possible to discharge deformable containers while aligning them in a certain direction with an extremely simple configuration.
