Abstract

PURPOSE:To make a conveyed work dischargeable at an optional place, by installing the mobile truck provided with a guide roller capable of developing an outward route part into a plane form, in case of a device which makes the outward route part of a conveyor belt round upward and houses the conveyed work in this rounded part for conveyance. CONSTITUTION:Front and rear wheels 14 and 15 at a lower part of a mobile truck 13 are placed on rails 12 and 12 laid down on a support frame 7 of a pipe conveyor. An upper surface of the mobile truck 13 is set down to an ancline 13a gradually rising toward the front, and an upper guide roller 18 is installed in the front end, while a lower guide roller 20 is attached to a space between these front and rear wheels at the lower part of the mobile truck 13. With this constitution, an outward route part 6a of a conveyor belt 6 is gradually developed from a circular form to a plane form at an interval ranging to the upperguide roller 18, and after passing through the lower guide roller 20, the outward route part is made round upward again by a form keeping roller 8 at an adapter plate 7d and traveled. Then, a discharge pipe 21 us installed in a front end part of the mobile truck 13, thereby making the conveyed work dischargeable.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention provides a method for forming a flat belt in the -L direction into a pipe shape or a TJ.
This invention relates to a pipe conveyor that is rolled into a shape so that the conveyed objects can be conveyed without scattering.

(Prior Art) As schematically shown in FIGS. 6 and 7, an endless belt-shaped rubber conveyor belt ( 33), and at least its upper forward path is covered with a large number of shape retaining rollers (34).
), the pipe conveyor is rolled upward into a pipe shape, and the conveyed object (36) introduced from a hopper (35) provided near the rear roller (32) is wrapped and conveyed therein. be.

In this device, the conveyed object (36) is ejected, that is, dropped onto the conveyor belt (36) at the front roller (31).
33) is performed when it is reversed downward.

(Problems to be Solved by the Invention) In the pipe conveyor as described above, once it is installed, the discharge location of the conveyed objects is fixed and cannot be changed.

The present invention enables objects to be transported to be freely discharged at any point along the length of a pipe conveyor once installed.

(Means for Solving the Problems) The present invention rolls most of the upper forward path portion of the endless conveyor belt, which is passed around the front roller and the rear roller, into a pipe shape using a large number of shape-retaining rollers. A pipe conveyor that accommodates and conveys objects, which has an inclined surface that rises toward the front, has an upper guide roller at its front end, and has a lower guide roller below it. A cart is provided so as to be movable parallel to the upper forward path portion of the conveyor belt, and the upper forward path portion of the belt is looped around the upper surface and front surface of the upper guide roller in a flat state through the inclined surface of the moving cart. Then, it is made to run toward the front roller via the rear and lower surfaces of the lower guide roller.

(Function) According to the pipe conveyor of the present invention, even after it is once installed, the dropping position of the conveyed object can be changed to any position in the longitudinal direction by a simple operation.

(Embodiment) FIGS. 1 to 5 show an embodiment in which the present invention is applied to a pipe conveyor.

(1) is a front roller, and (2) is a rear roller, both of which are rotatably installed at required positions on the pedestal (3), and the front roller (1) is attached to the front end of the pedestal (3). motor (
4), it is driven via the chino (5).

An endless conveyor belt (6) made of rubber and having a tendency to curl around its longitudinal axis is wound between the rollers (1) and (2).

The portion of the frame (3) excluding the front end and rear end has a height higher than that including the upper outgoing path portion (6a) and the lower backward path portion (6b) of the conveyor belt (6), and Conveyor belt (
A large number of support frames (7) perpendicular to the running direction of the vehicle (6) are fixed at approximately constant intervals.

The support frame (7) is as clearly shown in FIG.

A pair of outer rods (7a) (7a) and inner rods (7b) (
7b) are connected to each other by a bottom rod (7c), and a support plate (7d) is stretched between the inner rods (7b).

A U-shaped recessed hole (7e) with an open top is formed at a key point in the upper part of the support plate (7d), and a circular hole (7f) is formed at a key point in the lower part of the support plate (7d).
) is cut out.

The support plate (7d) is located parallel to the mounting plate (7d) and on the same circumference of the side and lower part of the recessed hole (7e) and the periphery of the circular hole (7f). A plurality of shape-retaining rollers (8) and (9) are mounted on rackets (lo) with bearings.
It is pivoted with (11).

These shape-retaining rollers (8) and (9) allow the conveyor belt (6
) runs upward in a rounded state in a circular or U-shape in its upper outgoing portion (6a), and in its lower returning portion (6b), its side edges are overlapped with each other as lower sides. It is designed to run in a circular manner.

A longitudinal rail (12) is attached spanning the top surface of the outer rod (7a) of each support frame (7).

On the rails (12) (12) are mounted axles (14) (15) at the front and rear lower portions of the movable trolley (13). The rear axle (15) is driven by a motor (16) attached to the moving truck (13) via a chino (17).

The upper surface of the movable cart (13) is a sloped surface (13a) that gradually rises toward the front, and an upper guide roller (18) is attached to the upper front end of the sloped surface (13a).

Furthermore, as shown in FIG. 4, a plurality of sets of holding rollers (19) arranged in a V-shape from side to side are attached to key points on the inclined surface (13a) of the movable trolley (13).

Front and rear axles (+4) (1) at the bottom of the moving trolley (]+3
5), a lower guide roller (20) is installed.

As a result, the forward path portion (6a) of the conveyor belt (6) is
Rising along the slope (13a) of the mobile cart (13),
After the guide roller (18) is unfolded into a flat shape on the upper surface, it passes through the front surface of the guide roller (18), goes rearward and downward, passes through the rear and lower surfaces of the lower guide roller (20), and heads forward, and then extends to the mounting plate (7d) in front of it. ) The shape-retaining roller (8) causes it to roll upward again into a circular or U-shape and travel.

In addition, at the front end of the movable trolley (13), a vertical discharge tube (21
) is permanently installed. The lower part (21) of this discharge tube (21)
a) is divided into left and right halves and opens at the lower portions on both sides of the pedestal (3).

A fixed discharge tube (22) is provided at the front end of the pedestal (3) at a portion including the front roller (1).

Immediately after the front roller (1) on the gantry (3), an appropriate number of tension rollers (23) are provided to take up slack in the return path portion (6b) of the conveyor belt (6).

In the pipe conveyor of the present invention having the above configuration, no matter where the moving cart (13) is located on the rail (12),
The upper outgoing portion (6a) of the conveyor belt (6) is always
After moving up the slope (13a) of the movable trolley (13) and unfolding it flat, it moves toward the front roller (1), so that the transported objects (2) loaded near the rear roller (2)
4) is thrown into the discharge tube (21) and discharged when passing the guide roller (18) of the movable trolley (13).

Therefore, the movable cart (13) can be moved to a desired position in the longitudinal direction of the pedestal (3) by the motor (16), and the transported object (24) can be discharged at that location, which is convenient. be.

Moreover, the movement of the mobile cart (13) is carried out using the conveyor belt (6).
This is convenient because it can be done freely even while driving.
