Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a cleaning device for a box called a plastic return box, that is, a P box for storing and transporting beer bottles, for example.

[Conventional technology]

Generally, a container for storing and transporting beer bottles and the like is made of plastic, and after being used, the container is reused by washing with a high-pressure jet or a brush. However, if the stains were particularly severe, they were manually taken out of the cleaning line and washed in a place different from the cleaning line.

As a cleaning device for cleaning such a returnable box, a cleaning section for spraying a cleaning solution to wash the returnable box and a rinse section for rinsing the returnable box washed by this cleaning section on the same plane are provided. Some are connected in series.

[Problems to be solved by the device]

However, in the case where the cleaning section and the rinsing section are connected in a plane in series, the entire apparatus becomes long, and therefore the installation area becomes very large. Furthermore, since the cleaning solution is still attached to the surface of the carrying box that has been washed in the cleaning section, supplying the carrying box to the rinsing section in that state not only requires a large amount of water for rinsing the cleaning solution, There has been a problem that the area of the entire rinsing portion is increased to secure the rinsing time.

In view of such a point, the present invention aims to provide a compact box cleaning device having a small installation area of the entire device.

[Means for Solving the Problems]

Therefore, the present invention is a box cleaning device for cleaning a box for storing a container such as a bottle, and a rinsing section for rinsing a box after cleaning, in which a cleaning section for injecting a cleaning liquid to clean the box is placed on the upper stage. Was arranged in the lower stage, and a free-falling part for free-falling the cleaned box was formed between the cleaning part and the rinsing part.

[Action]

The box is supplied to the cleaning section arranged in the upper stage through the lifter section, and cleaning is performed by nozzle spray of the cleaning liquid in the cleaning section, and the box after cleaning is guided to the upper end of the free fall section, and from the upper end of the free fall section. The box after washing for a predetermined distance is allowed to fall freely, and after the liquid is drained, the box is supplied to a rinsing section provided on the lower side of the cleaning section, and the box that has been drained at this position is rinsed with water. Since the box after cleaning in the free-falling section falls freely by a predetermined distance, the cleaning liquid adhered to the surface of the box in the cleaning section when shock-supported by the receiving member of the box formed under the free-falling section. Scatter, and the cleaning liquid is well drained. Moreover, since the cleaning section and the rinsing section are arranged vertically, the installation area of the entire apparatus is reduced.

Next, the operation of the box cleaning device of the present invention will be described.
First, the dirty box P is manually pulled out from an ordinary cleaning line and is successively supplied from the lower part of the lifter section 2 of the box cleaning apparatus 1 of the present invention onto the support plate 13 of the transport chain 10 which advances one pitch at a time. The box P carried to the upper part of the lifter part 10 by the carrying chain 10 is supplied to the inlet of the washing part 3 by the pushing plate 15 and sent onto the carrying chain 20 provided at the lower part of the washing part 3 to be dirty. When the box P passes through the nozzle pipes 24, 25, 26, it is cleaned by the heating cleaning liquid sprayed from them, and the upper surface of the box P has a box guide.
Guided by 27. When the box P which has been cleaned by the cleaning section 3 reaches the outlet (left side in the figure) of the cleaning section 3, the retracting rod 30 provided on the upper part of the free fall section 5 is rotated clockwise in FIG. The inner side surface of the front side wall of the box P is pushed leftward in the figure, and the box P is placed on the shutters 34, 34. When the box P is placed on the shutters 34, 34, the drive cylinders 35, 35 are operated to swing the shutters 34, 34 downward to release the lower surface of the box P. When the lower surface of the box P is released, the box P freely falls, and falls on the rubber rollers 41, 41 ... 41 as a receiving member provided in the lower portion of the free fall part 5 in a buffer manner. By this drop, the cleaning liquid adhering to the surface of the box P is scattered and separated from the surface. The box P in which the liquid has been drained in this way is sent into the rinsing section 4 by the operation of the pushing bar 39, and the box P is moved by the transport chain 110 provided in the rinsing section 4 so that the box P is connected to the nozzle pipe 53 ,. After passing 54,94, this nozzle pipe 53,54,94
Rinse water is sprayed onto the surface of the box P from a large number of nozzles when passing through, so that the cleaning liquid adhering to the surface of the box P is completely washed off. The box P in which the cleaning liquid has been washed off by the traveling of the transport chain 110 is a stop plate shown in FIG.
When the box P comes into contact with the contact plate 63 and the contact plate 63 comes into contact with the contact plate 63, the pusher 57 operates to press the rear surface of the box P toward the discharge plate 67 and discharge the discharge rollers 64, 64, ... A clean box P that has been washed and rinsed is discharged onto the plate 67.

[Effect of device]

Since the present invention is configured as described above, the entire apparatus can be made compact and the washing liquid adhering to the box can be drained, so that it is not necessary to perform sufficient rinsing, and the size of the rinsing portion can be made small. It also has the effect of reducing the volume of rinsing water used in.
