Abstract

PURPOSE:To simplify a pipelike endless belt in structure by expanding an inner surface of a pipe conveyor before drum rotation, and making it so as to be set down to an outer surface of this pipe conveyor to be formed after the drum rotation, in case of the pipelike endless belt for granules. CONSTITUTION:An endless belt 1 is molded in a tubular from as being rounded into a pipe from whose belt surface 1a is set down to the inner surface after turning its overlap upside at an outward passage between a driving drum 2 and a driven drum 3 to be shown an arrow A, and, it is expanded at a spot short of the driving drum 2, rotating this drum 2. Next, it is rounded into the pipe form again and entered in a return passage, but at this time, the overlap is turned upside and rounded with an inner surface 1a of the belt set down to an outer surface of a pipe tubular part 5, it is rexpanded at a spot of a driven drum 6, discharging granules, and after passing through the surface 1a, it is put back to the pipe from. With this constitution, the structure is simplified.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is characterized in that an endless belt that reciprocates between two locations is rolled into a pipe shape, and powder and granules are wrapped in the belt and continuously conveyed. This invention relates to a reciprocating conveyance method using a pipe conveyor.

[Conventional technology]

Conventionally, as a reciprocating conveyance method for this type of pipe conveyor, as disclosed in Japanese Patent Application Laid-Open No. 58-104807, an endless belt is folded back from the end point of the forward path and a backward belt is developed into a flat belt. By twisting 180 degrees around the axis in the direction of movement and turning it over, the inner surface is turned upward into a pipe-like shape, and the powder and granules are wrapped and conveyed in the pipe-like belt, making effective use of the returning belt. There is something I measured.

[Problem that the invention seeks to solve]

In the above-mentioned reciprocating pipe conveyor device, the endless belt that has passed through the delivery roller device is turned over twice by 180 degrees by the first and second rotating rollers, so this turning operation is However, there are problems in that the pipe conveyor device requires a large amount of space and the structure of the pipe conveyor device is complicated.

[Means for solving problems]

- The method for reciprocating conveyance using a pipe conveyor according to the present invention includes:
A plurality of support devices each having a plurality of shape-retaining rollers pivoted on almost the same circumference are arranged at appropriate intervals, and an endless belt rolled into a pipe shape is mounted on two drums spaced at a constant interval. At that point, roll it out flat and hang it between the two drums.
A pipe conveyor that transports an object by wrapping the object therein and passing the object through the plurality of support devices.

A pipe-shaped endless belt with one side as an inner surface and an overlapping part as an upper part is made into a pipe-shaped belt with one side as an inner surface and an overlapping part as an upper part after going around the drum. It is designed to transport things.

〔Example〕

The present invention will be explained in detail below based on the drawings.

(1) is a flexible endless belt, which is shaped like a pipe with the longitudinal direction as its axis.A belt or the like is used which has an elastic tendency to be rolled up on either the front or back side.

This endless belt (1) has an upper half, that is, an arrow (
The driving drum (2) at the lower end of the forward path and the driven drum (3) at the upper end of the forward path shown in A) are rotated in a flat shape with the surface (la) as the outer surface, and the overlapping part (lc) is in the middle part. It is hung around each drum (2) and (3) so as to form a pipe-shaped cylindrical part (4) located above and having the surface (1a) as the inner surface.

Also, the lower half of the endless belt (1), that is, the arrow (B)
On the return trip shown by ↓, after going around the driving drum (2), a pipe-shaped cylindrical part (5) is formed with the overlapping part (lc) located above and the back surface (1b) as the inner surface, and the driven drum ( At the driven drum (6) slightly below 3), it is unfolded into a flat shape with the back surface (ib) as the outer surface.

The endless belt (1), which has been lowered in an overhanging manner from the driven drum (6), rotates in a flat shape between a pair of guide rollers (7) (7) while avoiding being slightly directly below it. , is hung around the driven drum (3).

(8) is a support frame arranged parallel to each other at a predetermined interval by connecting rods (9), and is partitioned into two upper and lower chambers (8a) and (8b) as shown in Figure 2. is,
Inside both chambers (8a) and (8b), a plurality of shape-retaining rollers (10) are provided, one on the same circumference, so as to substantially draw the inside.
The pivots are placed at equal intervals.

FIG. 3 shows the input port on the return trip. The endless belt (1) on the return trip, which is developed into a flat belt and goes around the drive drum (2) from below, supports its lower and side surfaces, respectively. Supported by rollers (11) (12), it is gradually rolled into a trough-like shape, between which.

Hopper (13) provided on the side of the endless belt (1)
from the upper end opening (13a) of the powder-like first transported material (1
4) is placed onto the endless belt (1).

This loaded first conveyed object (14) is transported to the cylindrical portion (5) on the return trip.
) After being stored in C and transported, it is discharged to a hopper (15) provided below the driven drum (6).

Similarly, the hopper (1) provided above the driven drum (3)
The second conveyed material (17) in the form of powder and granules introduced from step 6) is discharged to a hopper (18) provided below the drive drum (2).

In addition, (19) (20) are hopper (15) (1
8) The cleaning device 1, for example, a fountain nozzle, is installed adjacent to the back side (1b) and front side (1a) of each endless belt (1) that has passed around the driven drum (6) and the driving drum (2). Then, water or the like is jetted out to wash off the first and second conveyed objects (14) and (17) adhering to the endless belt (1).

In the above-described embodiment, after the conveyed object is conveyed, both sides of the endless belt are cleaned by the cleaning device.
In the case of objects to be transported that do not stain the endless belt, these cleaning devices can be omitted.

The above description is of a pipe conveyor in which the outer surface of the negative end and the inner surface of the other end of the endless belt (1) are overlapped and rolled into a pipe shape, as shown in FIG.

The present invention can also be applied to a pipe conveyor in which the inner surfaces of both ends of the endless belt (21) are overlapped and rolled into a pipe shape, or a pipe conveyor in which the edges on both sides are simply brought into contact or close to each other. Can be applied effectively.

〔Effect of the invention〕

As described above, the reciprocating conveyance method using a pipe conveyor according to the present invention not only conveys the conveyed object on both the outward and return trips, but also allows the front and back sides to be turned into inner and outer sides without the need to twist the endless belt 180 degrees and turn it over. Since a cylindrical portion is formed, the structure is simple and it is extremely effective in reducing installation costs.
