Description

[Detailed Description of the Invention] The present invention relates to a conveying body of a sorting slat conveyor that is suitable for conveying spherical articles that roll easily and are soft and easily damaged, particularly spherical fruits and vegetables.

Conventionally, the conveyors that transport these items include:
Conveyors shown in Japanese Utility Model Publication No. 43-910 and Japanese Utility Model Application Publication No. 52-66085 are generally used. The conveying body of these known conveyors has a group of raised hairs growing densely on the upper surface of the conveyor belt, but since the conveyor is a belt conveyor, it is usually necessary to provide a return belt receiving roller, a squeezing roller, etc. As shown in Fig. 1, the roller acts to crush the tufts, that is, the needle-like protrusions, so the tufts are worn out and are not durable and cannot be used for long periods of time. It had the disadvantage that it was only used for conveyors and could not be used for long conveyors.

In order to overcome this drawback, a conveyor was also proposed in which a raised member having the above-mentioned raised raised groups was adhered with adhesive to the upper surface of the conveyor body of a slat chain conveyor, as shown in Figs. 2 and 3. However, these conveyors have the drawback that the napped member can peel off from the conveyor body due to expansion and contraction of the napped member due to changes in temperature, deterioration of the adhesive, etc., and cannot withstand long-term use. In addition, the above conventional method using adhesive
Not only does it increase production costs because it has to be glued one by one to a large number of conveyor bodies, and it requires holding time until the adhesive hardens. I couldn't wrap it around and stick it on.

On the other hand, as shown in Japanese Utility Model Application Publication No. 46-15126, etc., the conveyor body of a conventional sorting slat conveyor equipped with a sorting function has a flat top surface shape, and can handle parcels and parcels. Although it is suitable for transporting and sorting, it is not suitable for transporting and sorting spherical fruits and vegetables that are spherical and easily rolled and damaged, and does not roll or damage spherical fruits and vegetables. The disadvantage was that it could not be transported and sorted.

The present invention has been made to eliminate these drawbacks.

With this invention, depending on the size of the spherical fruits and vegetables, it is possible to transport one fruit or vegetable per conveyor, but one fruit or vegetable can be loaded onto a series of multiple conveyors.
This is a sorting slat conveyor that rotates the conveyor in the middle of the conveyance path of the slat conveyor, which can also carry fruits and vegetables individually, and discharges and sorts fruits and vegetables on the conveyor. A synthetic resin material is injection molded and adhered to the upper part of the conveyor body by an injection molding machine, and the adhered member made of the synthetic resin material molded and adhered to the upper part of the conveyor body is A skin part that wraps around the upper part of the main body, a connecting part that connects the upper part and the lower part of the skin part through a plurality of holes penetrating the upper part of the carrier main body, and a connecting part formed on the upper surface of the skin part. It is made up of a large number of raised hairs, and the upper surface of the large number of raised hairs has a slope shape that slopes slightly downward from both left and right ends toward the center, and the large number of raised hairs has flexibility and elasticity. It is made so that it can be appropriately bent by supporting the weight of the spherical fruits and vegetables. In the present invention, when molding and adhering this adherend member, the conveyor body, which has a plurality of holes penetrating through the upper part of the conveyor body, is inserted in advance into an injection mold of an injection molding machine. A synthetic resin material such as soft PVC is molded onto the upper part of the conveyor body by injection molding to form a skin part that wraps around the upper part of the conveyor body, a large number of raised fluffs formed on the upper surface of the skin part, and a conveyor body. A connecting part that connects the upper part and the lower part of the skin part through the plurality of holes penetrating the upper part of the main body is an integral adherend member, and the adherend member peels off from the conveyor main body. In addition to ensuring that the conveyor can be used for a long period of time, the adhesive is automatically attached to the conveyor body at the same time as the adherend is injection molded to attach the adherend to the conveyor body. The present invention is designed to save time and effort in applying the material by hand, and furthermore, it is possible to apply the material to be adhered even to an extremely small conveyor body. or,
In the present invention, the upper surface of the large number of raised hairs is sloped slightly downward from both left and right ends toward the center, and the large number of raised hairs has flexibility and elasticity to form a spherical fruit or vegetable. A conveying body which is capable of stably conveying spherical fruits and vegetables without causing them to roll on the conveying body during conveyance by being appropriately bent by weight support, and which is also capable of conveying and sorting the fruits and vegetables without damaging them. That is.

The present invention will be explained below based on the drawings showing embodiments of the present invention.

FIG. 4 is a side view of the sorting slat conveyor device, and FIG. 5 is a sectional view of FIG. 4.

1 is conveyor frame, 2 is chain rail, 3
4 is a conveyor chain, and 4 is a large number of attachments provided on the chain 3 at predetermined intervals.

5 is a slat-shaped carrier body;
The conveying body of the present invention is made by attaching a member 6 to the upper part of the attachment member 6, which is attached to the attachment 4 by means described later, and is attached to the spherical fruits and vegetables 11.
It forms a sorting slat conveyor that is loaded with and conveyed. The conveyor of this sorting slat conveyor can place one fruit or vegetable on one conveyor depending on the size of the fruits or vegetables, but it can also place one fruit or vegetable on a series of multiple conveyors. The transport body is rotatably supported on one side, and has an engaging part for holding the transport body horizontally. Piece 12
The engagement piece 12 is attached to the attachment 4 via a rotatably attached holder 13, and is engaged when the rear part of the engagement piece 12 is pushed down by a discharge actuating device 14 that is activated by an external signal. When released, the carrier rotates from a horizontal position to a substantially vertical hanging position, and the fruits and vegetables 11 are discharged and sorted below. As shown in FIGS. 6, 7, and 8, the adhered member 6 molded and adhered to the upper part of the carrier body 5 is a carrier having a plurality of holes 5a penetrating the upper part of the carrier body 5. The main body 5 is molded and adhered to the upper part of the conveyor main body 5 using a synthetic resin material such as soft PVC by insert injection molding, in which the main body 5 is inserted in advance into an injection mold of an injection molding machine and then injected. This adhered member 6 wraps around the upper upper surface of the conveyor main body 5, passes around the upper four circumferences of the main body 5, and is wrapped around the upper back surface portion, and a skin portion 6b formed on the upper surface of the skin portion 6b. A large number of raised bristles 6a are integrally molded, and through the plurality of holes 5a vertically penetrating the upper part of the carrier body 5, the upper portion of the upper surface side of the carrier body 5 of the skin portion 6b and the main body 5. The lower part wrapped around the upper back part of the connecting part 6c
The adherend member 6 is integrally molded so that it cannot be separated from the conveyor main body 5. In addition, as described above, the present invention is such that when the adherend member 6 is injection molded, the adherend member 6 is automatically adhered to the conveyor body 5 at the same time.
This eliminates the need for gluing and manual attachment. Furthermore,
As shown in FIGS. 5 and 6, the upper surface of the large number of raised bristles 6a of the adherend member 6 has a sloped shape with the central part being slightly lower than both left and right ends, and the upper surface of the large number of raised raised 6a
has flexibility and elasticity, and when a spherical fruit or vegetable 11 is placed on the many raised naps 6a, it supports the weight of the fruit or vegetable 11 and flexes appropriately. The spherical fruits and vegetables 11 placed on a conveyor can be stably conveyed without rolling during conveyance, and the fruits and vegetables 11 can be conveyed and sorted without damaging them.

As described above, in the present invention, the adhered member molded and adhered to the upper part of the conveyor body passes through the skin part that wraps around the upper part of the conveyor body and the plurality of holes penetrating the upper part of the conveyor body. Since it is made up of a connecting part that connects the upper and lower parts of the epidermis and a large number of raised hairs formed on the upper surface of the epidermis, the adhered material expands and contracts due to changes in temperature. Even if this occurs, since the adhered member has the connecting portion, the adhered member will not peel off from the conveyor body and can be used for a long period of time without maintenance.

In addition, the present invention uses insert injection molding to attach the adherend to the conveyor body, and when the adherend is injection molded, the adherend is automatically attached to the conveyor body at the same time. Because it is something that
It is possible to eliminate the trouble of gluing and manual attachment that were conventionally required to attach adherends to the conveyor body, significantly improving productivity, and making it extremely compact and complex-shaped. This has the effect that the member to be adhered can also be applied to the main body of the conveyor as desired.

Further, in the present invention, the upper surface of the large number of raised bristles of the adherend member has a slope shape with the center portion being slightly lower than both the left and right ends, and the large number of raised bristles have flexibility and elasticity, When spherical fruits and vegetables are placed on the large number of raised piles, it is designed to support the weight of the fruits and vegetables and flex appropriately, so that it is possible to prevent the fruits and vegetables placed thereon from rolling. The sorting slat conveyor using the conveyor of the present invention can stably convey spherical fruits and vegetables, and has the effect of preventing fruits and vegetables from falling from the conveyor and causing damage. be.
