Description

[Detailed description of the invention] "Industrial application field" This invention relates to a container washing device.
The present invention relates to a container washing device that prevents containers after washing from being recontaminated by water dripping from the ceiling of the enclosure.

``Prior Art'' Conventionally, as a container washing device, there has been provided a container conveyor disposed inside a case for conveying the containers, a finish cleaning means for finishing cleaning the containers conveyed by the container conveyor, and a container conveyor for conveying the containers. A draining section formed downstream of the final washing means for draining the finished washed containers, and a container discharging mechanism provided downstream of the draining section for taking out the containers from the container transport conveyor. It is known (Japanese Unexamined Patent Publication No. 111777/1983).

The container transport conveyor in the draining section is configured to transport the containers horizontally for at least a short period of time from the end position of the finishing washing means, so that the ceiling of the casing in this section is also horizontal. was formed.

``Problem to be solved by the invention'' However, since the upper part of the container is filled with steam from the cleaning means of each part, the container that has been cleaned by the final cleaning means passes through the draining section. At the same time, the container was transported in steam, and the steam condensed on the container, making it impossible to drain and cool the container effectively.

In particular, since the ceiling of the enclosure in the draining section was horizontal, water adhering to the ceiling could drip onto the containers that had been washed, and there was a risk that the containers would be recontaminated.

"Means for Solving the Problems" In view of such circumstances, the present invention provides the above-mentioned container washing device in which the container transport conveyor in the draining section is moved along the forward direction in the transport direction from the end position of the finishing washing means. In addition to tilting downward, the ceiling of the enclosure in this portion is also tilted downward, and a collection means is provided for collecting water droplets that adhere to the ceiling and flow down along the slope.

"Function" According to this configuration, since the container transport conveyor in the draining section is inclined downward, it is possible to quickly pull the container to be transported downward from the steam at the upper part of the casing, and the steam is removed. Condensation on the container can be effectively prevented and draining and cooling can be performed well.

Since the ceiling of the enclosure in the draining section is sloped downward, the water adhering to the ceiling can be caused to flow down along the inclination and be collected by the collection means, thus removing the water adhering to the ceiling. can effectively prevent the liquid from dripping into the container.

"Example" The present invention will be explained below with reference to the illustrated example.
An endless container conveyor 3 for conveying containers 2 is disposed in a case 1 of the container washing device, and the container conveyor 3 holds the containers 2 with a number of holders (not shown) and moves them in the direction of the arrow It is designed to run in a circular manner.

A plurality of dipping tanks 4 are provided in the casing 1, and by sequentially immersing the container transport conveyor 3 in the dipping tanks 4 in a meandering manner, the containers 2 are sequentially immersed in the cleaning solution as required. It is now possible to perform cleaning.

A finishing washing means 5 is provided downstream of the soaking tank 4, and within the finishing washing means 5, the container transport conveyor 3 is disposed horizontally so that the containers 2 can be transported horizontally in an inverted state. , and an injection nozzle 6 for spraying hot water onto the containers 2 for final cleaning is provided on the upper side of the container transport conveyor 3, and a collection tank 7 for recovering the hot water injected from the injection nozzle 6 is provided on the lower side. There is.

A draining section A is provided at the downstream end of the final cleaning means 5 for draining the container 2 after final cleaning. In this draining section A, the container transport conveyor 3 is inclined downward from the end position of the final cleaning means 5 along the forward direction in the transport direction, thereby tilting the containers 2 and removing water droplets attached to each container 2. This makes it possible to effectively make it fall.

At this time, the partition wall 8 on the downstream side of the recovery tank 7 is extended obliquely upward so as to enter the first part of the draining section A, so that the washing liquid falling from the tilted container 2 in the draining section A is removed. Much of it can be recovered into the recovery tank 7.

In addition, in the draining section A, the ceiling 9 of the enclosure 1
is inclined diagonally downward along the container transport conveyor 3, thereby causing the water droplets condensed on the ceiling 9 to flow down along the slope of the ceiling 9, and collecting means 10 in the form of a groove provided below the ceiling 9. This makes it possible to collect the water droplets.

Further, on the downstream side of the drain section A, there is provided an inversion section B for inverting the inverted container 2 into an upright state, and on the downstream side of the inversion section B, the inversion section B turns the container 2 into an upright state. A container discharge mechanism 12 is provided for delivering the inverted container 2 from the container transport conveyor 3 to the discharge conveyor 11.

A drip tray 13 is provided on the downstream side of the reversing section B to receive water droplets dripping from the container 2 passing through the drain section A, so that the water droplets can be prevented from adhering to the lower container 2 that has passed through the reversing section B. I try not to.

It is preferable that the reversing section B is composed of an idle sprocket that guides the container transport conveyor 3, thereby improving the sanitary properties of the vicinity thereof compared to a case where the sprocket is used as a driving sprocket. . However, the reversing portion B is not limited to a sprocket, and may be formed of a guide rail.

In the above configuration, the containers 2 held by the container transport conveyor 3 and transported in the direction of the arrow are sequentially immersed and washed in each soaking tank 4, and furthermore, hot water is sprayed from the spray nozzle 6 in the final washing means 5. Finished and washed.

Then, the container 2 that has been finished washed is drained in a draining section A while being conveyed diagonally downward from a position just before passing over the finishing washing means 5. At this time, the upper part of the case 1 is filled with steam from the hot water etc. from the injection nozzle 6, but since the container 2 that has been finished washed is transported diagonally downward, the container 2 is transported horizontally. This makes it possible to quickly draw the steam downwards compared to the case where the steam is in the container, thereby effectively preventing the steam from condensing on the container. and cooling can be performed satisfactorily.

In addition, since the ceiling 9 of the enclosure 1 in the drain section A is inclined downward, water droplets that have condensed and adhered on the ceiling 9 can flow down along the slope and be collected by the recovery means 10. . Therefore, water droplets adhering to the ceiling 9 can be effectively prevented from dripping onto the containers 2 being conveyed through the draining section A, thereby preventing the containers 2 from being recontaminated. can.

Further, the container 2 that has been drained in the draining section A is reversed to an upright state when passing through the reversing section B, and is further discharged onto the discharge conveyor 11 by the container discharge mechanism 12.

``Effect of the invention'' As described above, according to the invention, the container can be drained and cooled well, and water droplets attached to the ceiling of the draining section can be prevented from dripping onto the container after washing. The effect is that it can be effectively prevented.
