Description of the Related Art Generally, in a bottle washing machine or the like, a container after a washing process is received by a container discharging device, extruded onto a dead plate, and further transferred from the dead plate to a discharging conveyor to be out of the machine. It is designed to discharge. The dead plate and the transfer surface of the discharge conveyor are at the same height, and if the condition of the containers after cleaning is the same, the timing at which all containers transfer to the discharge conveyor is almost the same, but the cleaning liquid adheres. Not all containers have the same frictional force between the bottom surface of the container and the conveying surface of the discharge conveyor and the outer periphery of the container and the side guides due to factors such as the state and dimensional error of the container.Therefore, the transfer timing to the discharge conveyor is shifted for each container It was the cause of falling bottles.

[0003] Specifically, the container on the upstream side in the transport direction of the discharge conveyor moves quickly, and collides with the container on the downstream side while being transported on the discharge conveyor, or transports the discharge conveyor. The container may come into contact with the side guide. In order to solve the above-mentioned problem, Japanese Patent Publication No. 53-38659 (JP-B-53-38659) discloses that the angle between the dead plate and the discharge conveyor is set to 95 degrees so that the traveling direction of the discharged container is not perpendicular to the dead plate. An evacuating device is described in which the arrangement reduces the collision of containers moving on the evacuating conveyor.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a side view of a container discharging device according to an embodiment of the present invention. The container discharging device is provided in, for example, a discharging portion of a bottle washing machine, and cleans a container 1 after washing. Discharge outside. The bottle washing machine circulates in the machine and circulates many containers 1
Is provided.

The conveying device 2 includes an endless chain 4 wound around a plurality of sprockets 3 arranged in a bottle washing machine,
The endless chain 4 is arranged in a plurality of rows (an arrangement of holders in the transport direction of the chain is referred to as "column", and an arrangement of holders in a direction perpendicular to the transport direction is referred to as "row").
A plurality of container holders 5 attached at predetermined intervals are provided. Containers 1 are inserted one by one into each of these holders 5 in a bottle supply unit (not shown), and the endless chain 4 travels so that the inside of the bottle washing machine is Is transported. During this transport, the cleaning liquid is sprayed onto the container 1 held by the holder 5, or
After being immersed and washed in the washing liquid tank and subjected to a draining step, it is taken out of the holder 5 in the bottle discharging section shown in FIG. 1 and discharged outside the bottle washing machine.

The holder 5 holds the container 1 in an inverted state until it reaches the sprocket 3 of the bottle discharging portion shown in FIG. 1, and turns the container 1 upside down while rotating around the sprocket 3. Let it. The container 1 is moved downward along the moving path 16 of the holder 5 from the side where the holder 5 is turned upside down.
The support plate 6 that supports the bottom surface of the container 1 is disposed, and the container 1 that has fallen out of the holder 5 when the holder 5 is inverted is supported by the support plate 6 and moves together with the holder 5. On the downstream side of the support plate 6, a chute 7 is arranged at a predetermined interval (an interval at which the container 1 can pass). The chute 7 is arranged to be inclined rearward, and is provided with vertical guide rails 8 attached at regular intervals (see FIG. 3).
Thereby, the endless chain 4 is divided into the same number of drop passages as the number of rows of the holders 5. One row of the container 1 continuously conveyed by the endless chain 4 passes through the support plate 6 and at the same time comes out of the holder 5 and falls along the divided passages of the chute 7.

Behind the chute 7, there is provided a rotary cam 11 (pressing means) which rotates about a rotating shaft 10. The rotary cam 11 has the same number of cam plates 12 as the number of rows of the chutes 7 (the number of drop passages).
The space between the chutes 7 can protrude toward the front of the chutes 7. Each cam plate 12 has an axis O of the rotating shaft 10.
Cam portions 12a formed symmetrically at two locations with respect to 1;
12a, 12b, and 12b. Each of the cam portions 12a, 12a, 12b, and 12b receives the container 1 falling from the chute 7 by the 12b while the rotary cam 11 rotates 180 degrees, and the dead portion arranged below the chute 7 by the 12a. The container 1 placed on the plate 9 is pressed and advanced by a predetermined amount. As shown in FIG. 3, the dead plate 9 is disposed at a predetermined interval so that the cam plate 12 can pass therethrough, and a side guide 14 for guiding both sides of the moving container 1 is provided.

In front of the dead plate 9 (the left side in FIGS. 1 and 2 and the lower side in FIG. 3), a discharge conveyor 13 running in a direction perpendicular to the moving direction of the container 1 which is pushed and moved by the rotary cam 11. Is disposed, and the cam plate 1 is provided.
A section from the end of the dead plate 9 that receives the container 1 from the second to the discharge conveyor 13 forms a discharge path 15 of the container 1. The container discharge path 15 is divided into multiple rows of moving passages 16 by side guides 14 fixed at predetermined intervals on the dead plate 9, and the containers 1 move one by one in each moving passage 16. .

The discharge conveyor 13 is arranged so that the container discharge path 15 is inclined upward, and the height of the discharge conveyor 13 is substantially the same as the mounting surface of the dead plate 9. This inclination angle is the container 1 to be processed.
Although various angles are conceivable depending on the type and the like of the container, any angle may be used as long as the container does not fall when the container moves onto the discharge conveyor 13. In this embodiment, the inclination angle is 1.5 degrees. The means for pressing the container 1 is not limited to the rotary cam 11, but may be a cam, a chain, or a means that moves linearly. In addition, 17 in FIG. 2 is a conveyor guide.

The operation of the container discharging device according to the above configuration will be described. When the container 1 washed while being conveyed by the endless chain 4 in the bottle washing machine reaches the bottle discharging section, the holder 5 of the endless chain 4 rotates around the sprocket 3 to be inverted. The container 1 comes out of the state 5. A support plate 6 is arranged from the periphery of the sprocket 3 to the lower side, and the container 1
Moves with its bottom surface being supported by this support plate 6. As described above, the endless chain 4 continuously transports the containers 1 in a plurality of rows, and one row of containers 1 reaching the tip of the support plate 6 comes out of the holder 5 and slides down on the chute 7.

The container 1 that has slid down each drop passage on the chute 7 is received by the cam portion 12 b of the cam plate 12 of the rotary cam 11 rotating on the rear side of the chute 7 and is placed on the dead plate 9. Then, the rear surface is directly pushed by the cam portion 12a of the cam plate 12 to advance on the dead plate 9 and move to the position shown in FIG.

The endless chain 4 of the bottle washing machine continuously transports the containers 1, and the containers 1 for one line are transferred onto the dead plate 9 by the rotary cam 11 while moving. Then, the container 1 in the next row falls in the chute 7 past the downstream end of the support plate 6. These containers 1
After being received by the cam portion 12b of the cam plate 12 of the rotary cam 11, the rotary cam 11 is also transferred to the dead plate 9 and advanced.

When the container 1 is pushed by the cam plate 12 and moves to the position A, the container 1 previously moved and at the position A is pushed by the succeeding container 1 and
To the position B in FIG. Similarly, when the succeeding container 1 is pushed by the cam plate 12 and moves forward, the dead plate 9
The preceding container 1 in the standby state above is sequentially pushed forward one container at a time. In this embodiment, the two containers 1 can stand by on the dead plate 9, and when the third container 1 is discharged from the bottle washing machine, the containers waiting at the position B are set. 1 is progressively advanced into the area of the discharge conveyor 13 by being pushed by the following container 1.

As described above, the discharge conveyor 13 is disposed so as to be inclined so that the discharge path 15 side is upward, so that even if the container 1 slightly advances to the area of the discharge conveyor 13, The bottom surface of the container 1 is hardly affected by the conveying surface of the discharge conveyor 13, and the container 1 is supported only by the dead plate 9. Further, when the container 1 advances and the area of the bottom surface that enters the discharge conveyor 13 side is larger than half of the bottom surface of the container 1, that is, the area of the bottom surface supported on the dead plate 9, the container 1 is moved to the dead plate 9. Conveyor 13
Transfer to. At this time, in addition to the frictional force of the conveying surface of the discharge conveyor 13, the container 1 is subjected to a force to slide down to the conveyor guide 17 side, so that the container 1 is not affected by the amount of moisture adhering to the container 1. A large shift is less likely to occur in the transfer timing of one row of containers 1 discharged from the bottle washing machine to the discharge conveyor 13.

[0020]

According to the present invention, as a result of employing the above configuration,
The following effects can be obtained. (1) Since the discharge conveyor is arranged at an angle so that the discharge path side is upward, the container can smoothly transfer from the dead plate to the discharge conveyor, and trouble such as falling bottles when transferring to the discharge conveyor is reduced. be able to.
