Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an automatic control device for a reciprocating conveyor-type loading platform developed to facilitate cargo handling operations and improve the efficiency of the operations.

(Prior Art) In order to facilitate the loading and unloading of powder and granular materials, etc., a reciprocating conveyor-type loading platform in which the loading platform of a vehicle (freight vehicle) is movable has been developed. (Unexamined Japanese Patent Publication No. 1983-
No. 148106, JP-A-58-193810, U.S. Patent No.
4143760, etc.) As shown in FIG. 2, the loading platform floor a has a large number of flooring materials 1 arranged in parallel and slidably in the longitudinal direction on the horizontal joists 2 of the vehicle body, and each of these flooring materials 1 is arranged in the left-right direction between the horizontal joists 2 on the lower surface of the flooring 1, and is connected to three drive beams 3a-3c, which are slidable in the front-back direction, through connecting members 4a-4c. fixed in rotation, three groups 1a-1
It is divided into c.

Each of the drive beams 3a to 3c is a drive member 6a to 6 which is disposed on the lower surface of the horizontal joist 2 so as to be slidable in the front and rear direction by a guide member 8 via a support member 5.
Each is fixed at c. The drive member 6a~
One end of the cylinder 6c is connected to each of cylinders 7a to 7c provided on the lower surface of the flooring 1 near the rear of the vehicle body.

As shown in FIG. 3, each of the flooring materials 1 is slidably fitted to a guide pipe 8 fixed in parallel on a horizontal joist 2 via a resin bearing 9.
Further, a slight 〓H is provided in order to eliminate sliding resistance with other adjacent flooring materials 1 during sliding movement. The hole H is closed off with a sealing material 10 made of an elastic material so that powder, grains, etc. do not spill from the hole H.

(Problems to be Solved by the Present Invention) However, in this conventional sealing structure, the corner portions of the flooring material 1 are formed at right angles, and the sealing material 10 is a sealing material formed on the side surface of the flooring material 1. The base portion 10a is fitted into the fitting groove 1a, and the seal portion 10
Since the tip of b is in contact with the upper corner portion of another adjacent flooring material 1, a narrow and deep substantially V-shaped groove h is formed between the seal portion 10b and the flooring material 1. It will be done. For this reason, there was a problem in that particulate matter and the like accumulated as residue in the groove h.

Moreover, the conventional sealing material 10 has a sealing portion 1
0b is curved upward, and the lip portion 10
Since c is shaped to be joined to the floor material 1 on the fitting side, when pressurized water from car washing etc. is applied from the bottom surface of the loading platform floor a, the water will infiltrate from the above 〓H,
There was also a risk that the sealing member 10b of the sealing member 10 would be pushed up and enter the cargo compartment, thereby wetting the cargo and the like.

(Purpose of the present invention) Therefore, the present invention has been made in view of the above-mentioned conventional problems, and is a seal that does not allow residues such as powder particles to accumulate and does not allow car wash water to enter. The purpose is to provide structure.

(Means for Achieving the Object) To achieve this goal, the present invention provides a seal structure for a reciprocating conveyor type loading platform floor by forming a tapered surface along the longitudinal direction on both sides of the upper surface of each floor material constituting the loading platform floor. A sealing material fitting groove into which the base of the sealing material is fitted extends parallel to the tapered surface on one side of the tapered surface, and the sealing material is formed of an elastic resin material. , a base and a seal portion extending obliquely upward from the base and having a substantially arcuate cross section so that its lower surface joins a tapered surface formed on the other side of another floor material adjacent to the tapered surface; , a lip portion extending obliquely downward from the base portion and joining to the other side surface of the adjacent floor material, the base portion of the sealing material being fitted into the sealing material fitting groove, so that the lip portion extends diagonally downward from the base portion and is attached to the other side surface of the adjacent floor material, and The intended purpose is achieved by creating a structure in which the bottom of the material is closed.

(Function) With the above configuration, when the sealing material is fitted into the sealing material fitting groove of the flooring material, the sealing portions are placed on the tapered surfaces of the flooring material adjacent to each other, and both of the tapered surfaces It is formed into a substantially arcuate cross section along , and is interposed between both tapered surfaces.

In addition, when the lip part is pressed against the other side surface of the adjacent flooring material, a downward rotational force acts on the lip part, and this rotational force causes the sealing part to be pressed against the other side surface of the adjacent flooring material. Since the tip side that is joined to the tapered surface of the material is pulled downward, the tip side is pressed against the tapered surface. On the other hand, the proximal end of the seal part is pressed into contact with the tapered surface of the floor material to which the seal material is attached by the base part fitted into the seal material fitting groove, so that the lip part Rotating force is not applied to the proximal end side.

(Embodiments) The present invention will be described below with reference to illustrative embodiments.

Reference numeral 11 denotes a floor material constituting a reciprocating conveyor-type loading platform floor, and the floor material 11 can slide on a steel guide pipe 12 fixed in parallel to the horizontal joist of the vehicle body via a resin bearing 13. is mated to. Tapered surfaces 14a, 1 are provided along the longitudinal direction on both edges of the upper surface, which are the upper corners of the flooring 11.
4b is formed, one of which has a tapered surface 14.
On the tapered surface 14a, a sealing material fitting groove 15 into which a base 17 of a sealing material 16 to be described later is fitted is formed.
It extends parallel to the

Reference numeral 16 denotes a sealing material for closing the hole H formed between the flooring material 11 and the adjacent other flooring material 21, and is made of an elastic resin material such as rubber or high-density polyethylene. A base 17 that is fitted into the sealing material fitting groove 15, and a tapered surface 24b extending diagonally upward from the base 17 and formed on the other side of another floor material 21 adjacent to the tapered surface 14a has a lower surface. a seal part 18 formed in a substantially arcuate cross-section so that the seal part 18 and the lip part 19 extend diagonally downward from the base part 17 and whose tip joins to the other side surface 21a of the other adjacent flooring material 21. have.

In addition, the number 22 in the figure is a guide pipe that attaches another adjacent flooring material 21 to the vehicle body via a bearing 23 in a slidable manner, and 25 is a sealing material formed on the tapered surface 24a on one side of the flooring material 21. This is a fitting groove.

(Effects of the present invention) As described above, according to the present invention, tapered surfaces are formed on both sides of the upper surface of each floor material constituting the reciprocating conveyor type loading platform floor, and a sealing material is fitted to one tapered surface. In addition to forming the groove, the sealing part of the sealing material is formed to have a substantially arcuate cross section so as to be joined to both tapered surfaces of the adjacent flooring material, and the lip part is joined to the other side surface of the other adjacent flooring material. Since V-shaped grooves are not formed between the flooring materials as in the conventional method, not only can residue such as powder particles be eliminated, but also the lip area can be easily removed. Since the double-sealed structure of the seal portion and the seal portion can be used, it is possible to reliably prevent the intrusion of pressurized water during car washing.

Further, according to the present invention, since the seal portion is fitted into the recess formed by the adjacent tapered surfaces, the seal portion is not damaged by cargo.

Furthermore, according to the present invention, since the lip portion is longer than that of conventional products, it has the advantage of being easier to attach.
