Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in transporters such as powder and granular materials.

Conventionally, bags made of flexible materials such as turbolin, which are formed by covering a base fabric woven with synthetic fiber yarn with two thermoplastic synthetic resin sheets, have been widely used as a means of transporting powder and granular materials. Various improvements have been proposed and implemented to easily discharge the contents filled in this bag.
Although these bags make it easier to discharge the contents, they have drawbacks such as a complicated structure, troublesome handling, and an increase in cost due to the increase in manufacturing steps.

5 From this point of view, conventionally, a cloth bag formed in a substantially rectangular parallelepiped shape is provided with a filling chute, a take-out chute, an air venting device, etc., and is supported on a frame wall such as a loading platform on the side wall of the bag. A tilting structure is constructed in which support metal fittings are attached, and an air chamber is formed by covering the base 10 with a wire mesh on the bottom surface of the inside of the bag body with breathable cloth, and air can be forced into this air chamber from the outside. Powder container devices have been proposed which can be loaded into a flexible loading platform.

However, in this type of container device, 15
Since the overall shape of the bag is a rectangular parallelepiped, simply providing an air chamber in the bottom does not allow for smooth discharge of powder and granular material, nor is it possible to efficiently fill the powder. There is a point. Therefore, as a result of various studies and trial production20, the inventors decided to incline the lower half of the bag inward over its entire circumference, and to prevent the powder from flowing out onto one side of the tilted bag. By extending a channel to form an outlet, and by extending an inflow channel above the inlet to form an inlet, and by providing an air slide 25 that can be freely inserted and removed from the opening of the outlet, powder and granular material can be removed. It has been found that filling and discharging of the bag can be accomplished quickly and smoothly, and maintenance of the air slide and cleaning of the inside of the bag can be accomplished easily.

Therefore, the object of the present invention is to have a simple structure, to be able to manufacture the bag at low cost, to be able to fill and discharge the contents efficiently and quickly, and to be able to easily clean and maintain the inside of the bag. An object of the present invention is to provide a transporter for powder and granular materials that is easy to handle.

In order to achieve the above object, in the present invention, a rectangular parallelepiped bag is formed using 35 flexible sheet material, and an appropriate number of hanging devices and fixing devices are installed at predetermined locations on the outer surface of the bag. , an inlet for the powder and granular material is provided at the top of the bag, an outlet for the powder and granular material is provided on one side of the bag, and an air slide is provided in the bottom of the bag. In such transporters, the lower half of the bag is inclined inward over its entire circumference, and an outflow path for powder and granular material is extended to one side of the inclined bag, and this outflow path is The present invention is characterized in that an inflow passage for the powder and granular material is extended on the same side surface of the bag body provided with the bag, and an air slide is further provided so as to be freely inserted and removed from the opening of the outlet passage for the powder and granular material.

Next, preferred embodiments of the transport body according to the present invention will be described in detail below with reference to the accompanying drawings.

In the accompanying drawings, the transport body according to the present invention is formed in the shape of a rectangular parallelepiped using a flexible sheet material that is waterproof and tough, such as vinyl chloride tarpaulin, synthetic rubber, polypropylene cloth, or waterproof canvas. Bag body 1
An appropriate number of fixing devices 12 are attached to the top and sides of the outer surface of the bag body 10 by means such as welding or sewing, and hanging devices 14 are attached to these fixing devices 12. An inlet 16 for powder, granules, etc. is provided at the upper side of the bag 10, and a cylindrical inlet channel 18 made of the same flexible material as the bag body is attached to this inlet 16. Further, the bag body 10 has a lower side surface inclined inward to form a bottom portion narrower than the upper portion, and an air slide 22 is disposed within the bottom portion so as to be freely inserted and removed from an outlet to be described later. In addition, an outlet 22 for powder, etc. is opened at a position corresponding to one end of the air slide 20 in the lower part of the bag 10, and this outlet 22 is also bellows made of the same flexible material as the bag body. A square tubular outlet passage 24 is attached. In this case, it is preferable to attach a tightening belt 26 to a part of the outflow path 24 and to close the outflow path 24 by tightening the belt 26 with a stopper 28 disposed on the side surface of the bag body. On the other hand, the sliding surface 30 of the air slide 20 is made of a porous material such as canvas cloth, asbestos, ceramic, or synthetic fiber cloth that allows low-pressure air to pass through and has a uniform air permeability.
8 is configured to be inclined at an angle of 4 to 8 with respect to the outlet 22, and the air supply pipe 3 is connected from an external air supply device (not shown).
The powder and granules on the slide surface 30 are fluidized over the entire surface of the slide by low-pressure air pumped through the outlet 2.
2 to the outflow path 24.

Next, the functions and effects of the transporter according to the present invention configured as described above will be explained.

First, when filling powder or the like, the air slide 20 is inserted into the bottom of the bag 10, the outflow path 24 is folded with the air pipe 32 led out from the outflow path 24, and the belt 26 is closed. It is fixed with a stopper 28 to close the outflow port 22.

Next, after filling the bag 10 with powder or the like through the inflow path 18 and the inflow port 16, the inflow path 18 is closed by an appropriate means, and the bag 10 is suspended by the suspension tool 14. and transport it to the destination.

When discharging powder and granules, etc., after removing the belt 26 from the stopper 28 and opening the outflow path 24, the air supply pipe 32 of the air slide 20 is connected to an external air supply device (not shown), and the slide surface is The powder and granules are fluidized over the entire slide surface by low-pressure air jetted from the slider 30 and are discharged through the outlet 22 and the outlet 24.

As is clear from the embodiments described above, the transporter according to the present invention prevents the bridging phenomenon of powder and granular material inside the bag by inclining the lower half of the bag inward over its entire circumference. In addition, by providing the powder inlet and outlet on the same side, the powder can be taken in and out while the bag is always fixed, and the air slide can be easily avoided. The removable structure provides many advantages such as easy cleaning of the inside of the bag and easy maintenance of the bag.

Although the preferred embodiments of the transport body according to the present invention have been described above, it goes without saying that various design changes can be made without departing from the spirit of the present invention.
