Abstract

PURPOSE:To eliminate breakage of a shape holding frame and deformation of a belt to aim at smoothening conveyance, by providing such an arrangement that the intervals of shape holding frames in a curve section of a conveyer is made to be smaller than those in a linear section of the conveyer so that the load of each shape holding frame in the curve section is reduced. CONSTITUTION:A pipe-like conveyer belt 1 is forced to be entirely curved by means of several shape holding frames 6 when it travels in a horizontal curved section A, and therefore, the traveling resistance thereof becomes larger remarkably than that of a linear section B. Accordingly, the pitches of the shape holding frames 6 in the curved section is made to be smaller than those in the linear section B. With this arrangement, a load exerted to the shape holding frames 6 in the curved section A is reduced, thereby it is possible to smoothly guide the conveyer belt with the conveyer belt 1 being held in a cylindrical shape.

Description

Detailed Description of the Invention [Industrial Application Field] The present invention provides a pipe in which most of a circulating endless belt-shaped conveyor belt 1- is rolled up into a pipe shape, and an object to be conveyed is wrapped therein for continuous conveyance. It concerns conveyors.

[Conventional technology]

A conventional pipe conveyor has a large number of shape-retaining frames arranged at equal intervals to support and run a pipe-shaped conveyor belt.

[Problem that the invention seeks to solve]

When using a conventional pipe conveyor as described above in cold regions, the conveyor belt is usually made of rubber or the like, so while it passes through a straight section in a rolled state, it When the material is cured in the -m state, it requires an unimaginable force to bend the entire material.

Therefore, when the hardened conveyance bell 1- approaches the curved portion of the conveyor, a large reaction force is generated between it and the shape-retaining frame, and there is a risk of destroying the shape-retaining frame.

The running resistance is also noticeably higher.

In addition, in normal temperature or high temperature regions, if the distance between the shape-retaining frames at the curved portion of the conveyor is large, the conveyor belt 1-, which should be rolled into a cylindrical shape, deforms when passing the shape-retaining frame at the curved portion. The cylindrical shape may become elliptical or distorted, or a portion may become concave, resulting in increased running resistance.

[Means for solving problems]

The present invention improves the spacing between the shape-retaining frames at the curved portion of the conveyor.
By making the spacing narrower than the spacing between the shape-retaining frames in the straight section,
This is an attempt to solve the above-mentioned problems.

[For production]

In the pipe conveyor of the present invention, since the intervals between the shape-retaining frames at the curved portion are narrow, when the hardened conveyor belt passes through the curved portion, as in the case of use in a cold region, the reaction force applied to each shape-retaining frame is The force is dispersed and reduced, allowing the conveyor belt to be guided smoothly.

Furthermore, even in normal temperature or high-temperature regions, the pitch of the shape-retaining frames in the curved portion is small, so there is less risk of deformation of the conveyor belt for each shape-retaining frame.

The conveyor belt 1- can be guided while maintaining its correct cylindrical shape, and therefore the running resistance is significantly smaller than that of conventional pipe conveyors.

[Example] Fig. 1 and Fig. 2 schematically show an example of the pipe conveyor of the present invention, with Fig. 1 showing a straight section at both front and rear ends, and Fig. 2 showing a horizontally curved section in the middle.

The endless 4iF-shaped conveyor belt (1) has flat plate-shaped parts at both front and rear ends that are connected to the front roller (2) and the rear roller (2).
3), and is circulated in the direction of the arrow by a driving device (not shown).

Both rollers (2) (
3), there are a first rounding frame (4) and a second rounding frame (5), and between the two rounding frames (5) there are a number of shape-retaining frames (6), as shown in Fig. 2. As shown in the curved portion (A).

Adjacent shape-retaining frames (6) are arranged closer to each other than in the straight portion (I3).

As shown in Figure 3, at the top of the first round frame (4),
A horizontal rounding roller (7) and a pair of left and right rounding rollers (7) that slope outward and upward from both ends thereof, and a horizontal rounding roller (7) on the top of the second rounding frame (5).
7>, and a pair of left and right rounding rollers (7) facing upward from both ends thereof are respectively pivotally installed.

Note that the lower portions of both rounded frames (4) and (5) are vertically symmetrical with the upper portions and are not shown.

As shown in Figure 4, a pair of upper and lower circular window holes (9) are cut into the mounting plate (8) stretched over the vertical rectangular shape-retaining frame (6). is equipped with multiple shape retaining rollers ([O)
is arranged in an annular shape that is concentric with the window hole (9) and has a smaller diameter than the window hole (9).

As shown in Fig. 3, the outgoing bell 1=(la) is unfolded into a flat plate and runs around the rear roller (:() from below).
While passing through the first rounding frame (4), it is rolled into a gutter shape by a rounding roller (7).

At this time, the hopper (1) installed above the rear roller (3)
1), the conveyed object (12) is on the outgoing belt (I a )
The outgoing belt (1a) passes through the second rounding frame (5) and enters the -1 window hole (9) of the shape retaining frame (6). and shape-retaining roller (1
0), the object to be transported (12) is rolled into a pipe shape.
It wraps around and advances inside each shape-retaining frame (6).

The outgoing belt (1a) that has escaped from the shape retaining frame (6) at the upper end is
It is unfolded while passing the upper part of the second and first rounding frames (5) (4), and the conveyed object (12) is moved to the front roller (
2) into the receiving hopper (Ill) surrounding the container.

The return bell 1-(lb) that has run around the front roller (2) is
It is rolled in the same way as above, and the lower window hole (9
) and then circulates back to the rear roller (:I).

When the pipe-shaped conveyor belt (1) runs around the horizontally curved part (A), the entirety is forcibly curved by a large number of shape-retaining frames (6), so running resistance is lower than the straight part (B). ), but the pipe conveyor of the present invention has a pitch ht m11 of the shape retaining frame (6) of the curved part (A), so the pipe conveyor can convey the conveyor while maintaining the cylindrical shape of the conveyor bell h (1). Bells 1 to 1 can be guided smoothly.

Note that the "double chain" refers to the case where the pipe conveyor curves in the horizontal direction, but the present invention can be effectively applied even when the pipe conveyor curves in the vertical direction.

Furthermore, the above is a case of a pipe conveyor in which the outer surface of the negative end of the conveyor bell h(+) and the inner surface of the other end are brought together by ->lT and rolled into a pipe shape, but 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 conveyor belt (51) are stacked together and rolled into a pipe shape, or to a pipe conveyor in which both side edges are simply brought into contact or close to each other. can be used for.

In addition, a shape-retaining frame for guiding the outward belt (1a) and a shape-retaining frame for guiding the return belt (lb) are provided separately and independently from each other, and the pitch of the curved portion of each of them is set higher than the pitch of the straight portion. It may be small.

〔Effect of the invention〕

As mentioned above, in the pipe conveyor of the present invention, the pitch of the shape-retaining frames at the curved portion is fine, so the reaction force applied to each shape-retaining frame when the conveyor belt passes through that portion is dispersed and reduced, and the pipe conveyor can be smoothly conveyed. It has the advantage that it can guide the conveyor belt and can be used satisfactorily even in cold regions.

In addition, even when used at room temperature or in high-temperature areas, there is less risk of deformation of the conveyor belt for each shape-retaining frame at the curved part, and the conveyor belt can be guided in a straight cylindrical shape. This has the advantage that the running resistance of the conveyor belt can be maintained at a small value.

Therefore, the 1+ force only needs to be a small output, and at the same time, it does not put strain on the conveyor belt or the entire vibrator conveyor, which improves its service life.
