DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centrifugal dewatering device for a folding basket used in a dehydration step when washing a synthetic resin folding basket used for transporting articles such as vegetables, fruits or small parts. .

[0002]

2. Description of the Related Art Conventionally, when goods such as vegetables and fruits or small parts are transported by a cargo transportation vehicle such as a truck,
A paper packing box such as a cardboard box is used, and articles are packed and packed therein, and after unpacking the articles, the paper packing box such as a cardboard box is discarded. At Shakubin, such paper boxes are collected and reused.
Such paper boxes are often soiled or broken during transportation or the like, and thus their disposal rate is still high, which is extremely disadvantageous both economically and in terms of resource saving.

[0003] Therefore, such a transport container is made of synthetic resin such as plastic, and it is being surely reused. However, if such a synthetic resin transport container was transported in the shape of a container, that is, in the shape of a box or basket, even though the inside was empty, for example, at the source of the article,
Unnecessary space becomes too large, and waste is liable to occur in terms of a freight transport vehicle for transporting the space and a stocker yard for storing the same. Therefore, for example, such a synthetic resin transport container is formed in a basket shape without a lid, and when the inside is empty, both side walls are folded inward to form a thin plate shape, for example, to the source of the article as described above. It is considered that no useless space is generated when the sheet is transported. Such a foldable basket made of a synthetic resin is hereinafter simply referred to as a foldable basket.
Japan Co., Ltd. "

[0004] Fig. 11 briefly shows the usage of the folding basket. In this folding basket 1, as shown in FIG.
A side wall (hereinafter also referred to as a short side wall) 1b corresponding to a short side thereof and a side wall (hereinafter also referred to as a long side wall) 1c corresponding to a long side thereof stand perpendicular to the rectangular bottom member 1a. From a fully opened state (hereinafter also referred to as a fully opened state), first, as shown in FIG. 3B, the short side wall 1b is folded inward (hereinafter, this state, that is, only the long side wall 1c is opened). (Referred to also as a half-open state), and then, as shown in FIG. 3C, when the long side wall 1c is folded inward (hereinafter, also referred to as a closed state), the basket 1 is completely folded. It is in a folded state. In the closed state or the folded state, for example, if the sheet is conveyed to the conveyance source, no useless space is generated. When used as the basket 1, conversely, the side walls can be opened in the order of the long side wall 1c and the end / side wall 1b to form the basket 1 in a fully opened state. A large number of slit-shaped gaps are formed in the bottom member 1a, the short side wall 1b, and the long side wall 1c of the folding basket 1.

[0005]

However, the folding basket 1 made of such a synthetic resin, as described above, contaminates both the inside and the outside of the basket when conveying articles such as vegetables and fruits. I will. The folding basket 1 that has been soiled in this way is
Prior to re-use, it is necessary to wash the baskets. However, in the past, these baskets were completely opened by an operator and then the inside and the outside were manually washed.

However, in this case, the cleaning operation is troublesome, and the time required for the cleaning is enormous. Therefore, the present applicant transports the folding baskets made of synthetic resin stacked in a folded state to a cleaning device, and sprays a cleaning liquid on the inside and outside of the folding baskets in the latent image device to wash the folding baskets. Is transported to a reversing drainer, and while the folding basket to which the cleaning liquid is attached is turned over, a slight impact is applied to the folding basket to shake off the cleaning liquid attached to the folding basket, and the folding basket is stacked by a predetermined number of stages with a stacking device. After being piled up and transported to a centrifugal dehydrator, this centrifugal dehydrator is used to wash the folding baskets that are stacked on the turntable, rotated at high speed together with the turntable, centrifugally dehydrated, and then carried out.・ Developed a drying device.

In such a folding basket cleaning / drying apparatus, in the drying step after spraying a cleaning liquid onto the folding basket, since the folding basket 1 is made of a synthetic resin, hot air of 100 ° C. or more is blown. Since a so-called blower drying for drying cannot be adopted, a centrifugal dehydrator for centrifugally dehydrating the washing liquid is indispensable, but in order to improve the efficiency of this centrifugal dehydrator, the turntable is rotated at a higher speed. There is no other way to shorten the centrifugal dehydration time.

However, since the folding baskets are centrifugally dehydrated in a stacked state, the weight of these baskets increases, and the mechanical strength of each part becomes a problem, and the speed of the turntable cannot be easily increased. There were challenges.

The present invention has been made in view of the above-mentioned unresolved problems of the prior art, and it is possible to reliably prevent the heavy basket from moving out of the folded basket in a stacked state. It is another object of the present invention to provide a folding basket centrifugal dehydrator capable of rotating a turntable at high speed without receiving wind resistance during centrifugal dehydration.

At the same time, the air resistance can be reduced, and the stacked baskets are stored in the storage space in a state in which the stacked baskets are stored in the storage space so as to abut against the opening edge of the storage opening from the outside by the storage basket holding means. In addition, it is possible to reliably keep the folded baskets in the stacked state from projecting outward due to the centrifugal force at the time of high-speed rotation of the turntable.

Further, in the folding basket centrifugal dehydrator according to claim 2, in the invention according to claim 1, the folding basket holding means includes an opening / closing plate portion rotatably held on a rotation shaft;
It is characterized in that the opening / closing plate portion is constituted by an elastic body which biases one end of the opening / closing plate portion so as to abut against the opening edge of the storage opening from the outside.

According to the second aspect of the present invention, even if a large centrifugal force acts on the stacked folding baskets which are heavy in weight and have a simple configuration in which only the opening / closing plate portion and the elastic body are provided, these stacked stacking states can be achieved. Of the folding basket can be reliably prevented from protruding outward.

Further, in the folding basket centrifugal dehydrator according to the third aspect, in the invention according to the second aspect, the opening means is capable of moving forward and backward with respect to a lower end edge of the opening / closing plate portion of the folding basket holding means on the storage opening side. The opening / closing plate is configured to be pushed open into the storage opening against the elastic body by the actuator.

As described above, according to the centrifugal dehydrator for a folding basket according to the first aspect, the storage space for accommodating the folding baskets in the stacked state of the turntable is closed by the cylindrical surface. Therefore, when the turntable is rotated at a high speed by the rotary driving means, the air resistance can be reduced, and the storage basket is opened by the folding basket holding means while the stacked folding baskets are stored in the storage space. By being held in contact with the edge from the outside, the folding basket in a stacked state can be reliably prevented from jumping outward due to centrifugal force during high-speed rotation of the turntable, and the turntable can be made faster And the centrifugal dehydration time can be shortened.

According to the centrifugal dewatering device for folding baskets according to the second aspect, the folding basket holding means has a simple structure in which only the opening / closing plate portion and the elastic body are provided, so that the stacking state in which the weight is increased is increased. Thus, even if a large centrifugal force acts on the folding baskets, the stacked baskets can be reliably prevented from jumping outward and held.

Further, according to the folding basket centrifugal water cutoff device of the third aspect, the opening means has an actuator that can move forward and backward with respect to the lower end edge of the opening / closing plate portion of the folding basket holding means on the storage opening side, Since the opening / closing plate portion is configured to be pushed and opened into the storage opening against the elastic body by the actuator, by moving the actuator forward, the opening / closing plate portion of the folding basket holding means is rotated inward to open. Thus, the folding basket can be easily inserted into the storage space in a stacked state.
