Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is provided in a pipe conveyor equipped with a conveying means composed of a chain or a wire which moves within a pipeline by connecting extruded bodies such as blades for pushing an object to be conveyed at predetermined intervals. The present invention relates to a device for removing a conveyed object entangled in an extruded body near a discharge port of a pipeline.

[0002]

2. Description of the Related Art In a pipe conveyor having a link chain and a conveying means in which extruded bodies such as blades or buckets are connected at equal intervals, a pipe conveyor is circulated to drive various solid substances (for example, wood or Metal chips,
Earth and sand, mineral raw materials, metallic substances, paper products, plastics,
It transports fish and shellfish, snow, garbage, etc.) and other granular substances. FIG. 9 shows an example of a conventional link chain type pipe conveyor, which includes a straight pipe 1, a substantially L shape and a U shape.
A pipe run formed in a meandering shape is provided by being combined with the elbow pipe 2 which is bent like a circle. In this pipeline, a hopper 3 serving as an inlet for the transported object is provided at an appropriate location, and a discharge section 4 for discarding the transported object or transporting it to another pipeline is disposed at a predetermined location. ing.
An endless chain 5 is built in the inside of the link chain type pipe conveyor, and the endless chain 5 is provided on a drive casing 10 in which the discharge portion 4 is formed and is stretched around a drive wheel 9 driven by a motor M. The pipeline is stretched so as to connect the shortest distance and circulates (see FIGS. 10 and 11). Here, in the above-mentioned link chain type pipe conveyor, the folding direction of the endless chain 6 by the drive wheel 9 is not particularly limited, and may be the vertical direction (illustrated example) or the horizontal direction. Further, the pipeline may be laid out in a one-way way without folding back. The endless chain 5 is composed of a large number of egg-shaped links 6 which are connected to each other at right angles to each other. Blades 7 having circular outer circumferences are fixed at appropriate intervals, and the blade 7 conveys an object to be conveyed. It is like this.
Therefore, the endless chain 5 constantly circulates in contact with the inner peripheral surface of the inner corner of each corner portion of the pipeline, and the blade 7 abuts against the inner peripheral surface and turns while twisting the endless chain 5. When the blade 7 crosses the corner of the line, the blade 7 turns in the opposite direction by the repulsive force of the twist of the endless chain 5 and returns, and while repeating this, the blade 7 circulates to discharge the conveyed object. In such a link chain type pipe conveyor, the transported object pushed out by the blade 7 is discharged from the discharge port 4 by being dropped due to its own weight. However, when the transported object has a shape that is easily entangled like metal chips, it is transported while being entangled with the chain 5 and the blade 7, and does not fall freely at the discharge port 4 and remains in the return pipeline. Not only does it bring back to the factory, it causes a decrease in transport efficiency, but it also causes problems with the conveyor. On the other hand, if, for example, a metal skewer (not shown) is arranged so that its tip is close to the blade 7 and fixed in the pipe, the blade 7
An object to be conveyed that is entangled with a chain or a chain and protruding from the outer periphery of the chain can be hooked and separated. However, in the above configuration, since the skewers are fixed to the pipe, there is a risk that the conveyed object may restrain the movement of the blade 7 when the conveyed object entwined with the blade 7 or the like cannot be removed. Since it is not possible to determine the mounting position and the number of mounting skewers in advance, it is necessary to determine the optimum conditions depending on the load operation situation, which is a very troublesome work.

Such a problem is not limited to the link chain type pipe conveyor having the above-mentioned structure, but there is also a pipe conveyor in which a roller chain in which extruded bodies such as blades and buckets are connected at a predetermined interval in the pipeline of the pipe. The same problem occurs in the case of a structure in which a wire or other pulling member moves, and a solution to this problem is awaited.

[0004]

SUMMARY OF THE INVENTION The present invention was conceived in view of the above circumstances. A first object of the present invention is to convey a material to be conveyed which is entangled with the extruded body and protruding outward from the outer periphery thereof when the extruded body passes through. A pipe having a blow-off device that makes it possible to blow off an object, and does not restrain the extruded body by pivoting in the traveling direction of the extruded body and escaping when the conveyed object does not get tangled with the extruded body. To provide a conveyor. A second object of the present invention is to dispose the claw portion so as to be able to collide with the extruded body, to be able to pivot and escape in a direction orthogonal to the advancing direction of the extruded body, and to move in the advancing direction of the extruded body. To provide a pipe conveyor having a blow-off device capable of pivoting and escaping even if it is possible to more reliably separate the conveyed object entangled in the extruded body from the extruded body. .

[0005]

In order to solve the above-mentioned first problem, the present invention proposes, in a first aspect of the invention, to connect an extruded body such as a blade for pushing an object to be conveyed at a predetermined interval in a pipeline. In a pipe conveyor in which a conveying means composed of a chain or a wire for moving is installed, a pair of left and right blow-off portions arranged with a slight gap on both sides of the extruded body in the pipeline are formed. Is provided on the pipe so as to be pivotally movable in the moving direction of the extrusion body. In order to solve the second problem, according to the invention of claim 4, in the pipeline, a pair of right and left blow-off portions that can collide with each other are formed on both sides of the extruded body. Taking technical means of pivotally attaching the connecting base to the pipe so as to be pivotable in a direction orthogonal to the direction of advance of the extruding body, and pivotally attaching the connecting base to the pipe so as to be pivotable in the advancing direction of the extruding body. There is.

[0006]

In the invention of claim 1, since the blow-off portion is arranged with a slight gap between the extruding body and the lateral side of the extruding body, the object to be conveyed is entangled with the extruding body passing through the blow-off portion, and the expulsing portion is discharged. The portion protruding outward from the outer periphery of the abutment collides with the blow-off portion and is separated from the extruded body. Further, in the case of a conveyed object that cannot be separated from the extruded body, the expulsion part pivots in the same direction as the extruded body advances and is lifted up to pass through the extruded body, so that the progress of the extruded body may be restricted. Absent. According to the invention of claim 4, in addition to the above-mentioned action, the blow-off portion is set at a position where it can collide with the extruded body, so that the transported object entangled with the extruded body can be more reliably separated, and As the extrudate progresses, it opens outward and escapes, so that the extrudate is not obstructed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a pipe conveyor having a scrubbing device of the present invention will be described below with reference to the drawings. 1 to 4 illustrates a case where the device 12 is provided on the conventional pipe conveyor, and in the drive casing 10 connected to the reciprocating paths 11A and 11B of the pipeline, from the outward path 11A. The discharging unit 13 is pivotally connected to the discharging unit 4.

The stripping device 12 is made of a thick metal piece, and the pair of left and right stripping parts 13, 13 are connected to each other to form a gate shape. Further, an inverted U-shaped notch 14 is provided at the center of the removing device 12, and the blade 7 pulled by the chain 5 inside the notch 14 has a slight gap (in this embodiment, within a few mm). ) Are separated from each other (see FIG. 2).

The sharpening edge portion 1 is provided along the inner edge along the above-mentioned inverted U-shaped notch 14 on the wall surface facing the blade 7 on the entrance side of the advancing blade 7.
5 are formed (see FIG. 4). On the other hand, the removal device 1
A series of pivot shafts P1 projecting to the left and right are formed in the upper part of 2, and are pivotally attached to the drive casing 10 so as to be pivotable in the traveling direction of the blade 7.

When the chain 5 is reversed and moved in the reverse direction, it is sufficient to provide the above-mentioned scrubbing device in the vicinity of the discharge ports of the forward path and the return path of the pipeline. Furthermore,
The scraping device may be configured such that the scraping parts 13 are pivotally mounted in the drive casing 10 in two minutes.

Because of the above structure, the blade 7
The objects to be transported that are entangled without free fall due to their own weight
When passing through the inside of the hollow of the notch 14 of the scrubbing device 12, it collides with the peripheral portion of the notch 14 due to the clearance between the chain 5 and the blade 7 on the entry side thereof. Here, since the removing device 12 swings in the traveling direction of the blade 7 with the pivot P1 as a fulcrum, there is no hindrance to the traction traveling of the chain 5. However, the transported object is caught by the edge portion 15 and tries to separate from the chain 5 and the blade 7. Moreover, since the scraping device 12 is a thick plate and has its own weight of several kg in the illustrated example, it returns to the vertical position while swinging due to its own weight.
Is separated from and falls downward.

In the above-mentioned structure, the wiping device 15 is not in contact with the blade 7 and the chain 5, so that the wiping effect is limited. Therefore, by providing a scraping portion that directly contacts the blade 7, the scraping effect can be improved.

The stripping device 22 shown in FIGS. 5 and 6 has a pair of left and right parts in which a stripping portion 23 is pivotally attached to a connecting base 22A by a pivot P3 and a tip portion 25 is formed. It consists of Further, the connection bases 22A are pivotally attached to the drive casing 10 by pivots P2, are arranged in a left-right pair, and are pivotally attached along the traveling direction of the blade 7. Each of the connecting bases 22A is provided with a blow-off portion 2 which is pivotally movable laterally with respect to the traveling direction of the blade 7.
Three are pivotally attached. The scraping portion 23 is provided with a rod-shaped claw portion 25 at its tip and extends inward. The center of gravity of the scraping portion 23 is shifted so that the tip of the claw portion 25 collides with the advancing blade 7. As shown in FIG. 7, they are arranged in a cross shape.

Further, in the scrubbing device 32 shown in FIG. 8, the pair of connecting bases 32A are formed separately, and a common pivot P
2'shows a different embodiment pivotally attached to the drive casing 10 at 2 '. In this case as well, since the scraping portion 33 having the claw portion 35 is pivotally attached P3 to the connection base 32A and the center of gravity of each scraping portion 23 is displaced, the claw portion at the tip end in the vertical posture is centered. The position is approaching. The other structure is the same as that of the above embodiment.

Because of the above-mentioned respective constitutions, in the shaving devices 22 and 32, the left and right claw portions 25 and 35 are arranged in an intersecting manner toward the center line of the blade, and it is as if the chain 5 and the blade 7 were made. It is set by its own weight at a position that hinders its progress.

The blow-off portions 23 and 33 have a degree of freedom of pivotal movement in the front-rear direction and the left-right direction, and have a center of gravity such that they are close to the center line of the blade 7. Therefore, with the claw portions 25 and 35 arranged at the positions where they collide with the blade 7,
It is possible to reliably hook the moving object entangled with the blade 7 and the chain 5 that are moving forward and to dispose of the transferred object in the discharging portion 4. Then, the blow-off portions 23 and 33 pivot in the direction away from the center of the blade 7 to the side, and
Since it has a degree of freedom of pivoting forward along the traveling direction, the transported object can be separated without obstructing the traveling of the chain 5 and the blade 7.

[0017]

According to the present invention, since the blow-off portion is pivotally attached forward along the advancing direction of the extruding body, the extruding body, the chain or It is possible to cause the object to be conveyed, which is projected from the conveying means such as a wire, to collide with the scraping portion and be separated from the conveying means such as the extruded body, the chain or the wire. Further, when the blow-off portion is provided at the position where it collides with the extruded body, the blow-off portion is attached so as to be pivotable laterally from the extruded body. It does not obstruct the movement of the extruded body by removing the conveyed object and escaping from the moving direction of the extruded body.
