JPS5853530A - Unloading air bag for pulp chip - Google Patents

Abstract

PURPOSE:To enable easy unloading of pulverized chip, by inflating a bag body folded on the bottom of a cargo body of a truck in a triangle isosceles surface state when unloading the pulverized chip. CONSTITUTION:At the time of unloading, air is sent into a bag body 1 folded on the bottom of a cargo body of a truck 7 through an air supply opening 2, the bag body 1 is inflated so that triangle isosceles surfaces forming steep slopes on both sides of the bag body 1 are formed and chips 8 loaded on the cargo body of the truck 7 is discharged and fallen evenly on both sides of the cargo body by making use of the steep slopes. When the air is removed from an air discharge opening 3 of the bag body 1 after a discharge of the chips 8, the bag body 1 is folded flat on the bottom of the cargo body in a evenly plane state by making the tip into the center.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air bag for easily unloading valve chip materials loaded on a truck bed using air power.

Now, to explain the embodiment with a diagram, the main body (1) is made of a soft sheet body and has a triangular roof shape with a triangular prism placed horizontally, and an air inlet (2) and an air outlet (3) are provided. , the bottom peripheral edge 6ζ shall be provided with a mounting fin (5) and fixed to the truck bed surface with bolts and folded, and the rental vehicle internal number ζ
, a partition plate (41 (4)) is provided as a bottom plate whose width increases from the top of the triangle to the base, and when folded, the top line is reduced to the center number ζ equally and flat on both sides of the platform, and the air supply At the time of entry, the top ridge is swollen so that the center number ζ and both sides become a triangular isosceles surface.

In the figure, track (7) and track (8) indicate chip material.

In the past, unloading valve chip materials from trucks required a great deal of time and effort, as the process relied on manual labor.

This application aims to speed up work and save labor in unloading work.
When loading, the outside of the package is folded into the top of the truck bed, and the chip material is loaded, and when unloading, air is introduced into the package from the air inlet (2), and the bag is removed. The body expands to form a triangular isosceles surface with steeply sloped surfaces on both sides, and the internal partition plates (4) (4) hold the triangular isosceles surface and allow the chip material to be placed on the steeply sloped surface. The jars are placed evenly on both sides of the loading platform and can be discharged and dropped in an extremely short time and without requiring any human intervention. After discharging the chips, the air is removed from the air outlet (3) at an angle of 4°, and the partition plates are laid flat, and the main body is folded back to the bottom of the loading platform, with the top portion flat and even with the center plate.

The mounting body has a triangular top and a triangular beam (6) (6) as shown in Figure 4.
) may be attached at equal intervals to form an isosceles, and in the folded state, the apex line may be reduced equally and flat on both sides of the bottom surface of the loading platform.

As described above (this application usually folds onto the loading platform so that it does not get in the way of cargo, loads the chips as is, and when unloading, simply blows air or engine exhaust into the military bag). The steep slope of the bag, which expands into an isosceles shape, allows the powder chips to be discharged and dropped evenly on both sides, making loading and unloading of powdered chips extremely quick and requiring no manpower, resulting in labor savings and extremely high efficiency. be.

[Brief explanation of the drawing]

The drawings show an embodiment of the invention, in which Fig. 1 is a perspective view with a portion cut away, Fig. 2 is a front view of the folded state inside the loading platform, and Fig. 3 is a front view of the swollen and discharged state. , FIG. 4 is a perspective view of an applied example.

Claims (1)

[Claims] The entire body is made of a soft sheet and is used as a bag to feed air as needed.It is fixed to the bottom of the truck's bed and when folded, it shrinks evenly and flatly on both sides with the apex in the center, allowing air to flow in. An air bag for unloading pulp chips, which is characterized by expanding so that both sides become triangular isosceles surfaces around the top ridgeline when being fed.
