JPS597608A - Blade type conveyor capable of conveying upward - Google Patents

Abstract

PURPOSE:To enable an article to be smoothly conveyed without squeezing the article, by a method wherein, in a titled conveyor which prevents the production of crushed grain, the mounting angle of a blade mounted to an endless belt is changeable. CONSTITUTION:A blade moves along a conveying wall 7 of a conveyor casing 6 in a condition that the tip of the blade 4 makes light contact with the conveying wall, and an article A is pushed by the blade 4 to convey it along the wall 7. The charged article A, stayed on a bottom wall 8 once, is pushed from the under surface by the blades 4 passing in succession, and is raised along the wall 7. When reaching a discharge port 10, the article flows to the outside of the casing 6 by aid of inclination of the blade 4. Since the blade 4 has elasticity, the blade 4 is appropriately bent in a condition to make contact with the bottom wall 8, resulting in preventing the production of a high friction force between the tip of the blade and the wall 8 and in the ability to reliably convey all the articles without damaging any one.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vane conveyor capable of transporting articles on an upward slope, that is, from a gentle slope to a steep slope, and even vertically upward.

2. Description of the Related Art A vane type conveyor, in which vanes are attached to an endless strip that is driven in circulation, and articles are pushed by the vanes, has been widely used. However, this vane type conveyor can only be used to convey articles horizontally, and cannot be conveyed on a steep slope. For this reason, it is necessary to use a packet elevator or the like to transport goods on steep slopes, which complicates the structure of the transport device.
It is large in size, and the transportation cost per weight is high, especially when transporting small quantities, making it impractical.

In view of these points, the present invention improves the vane type conveyor and makes it possible to transport on an upward slope, thereby simplifying and downsizing the structure of the device, and in particular, for granular materials that must be prevented from being crushed. The purpose of this project is to provide a conveyor suitable for conveying small amounts of conveyance, and its features include the use of an endless belt with blades attached to it for circulation drive;
The angle of the blades attached to the belt can be varied to some extent depending on the flexibility of the belt, and the angle of the blades is adjusted to the angle of repose of the flow of goods, that is, to allow the goods to flow down naturally. with an angle of inclination greater than that possible,
In addition, at least the tip of the blade is made of an elastic body, and the elasticity of the blade and the variation of the mounting angle of the blade prevent the object from being crushed between the machine wall and the end of the blade, and the object can be smoothly moved. The reason is that it has been made possible to transport the objects upward.

Embodiments of the vane conveyor of the present invention will be described below with reference to the drawings. Belt (1) is -1 pulley (2)
(3) The hook is passed between the two, and by rotating one of the pulleys of the double, vl (1) moves in a circular manner. Wings (4) are attached to this belt (1) with fittings (5) at appropriate intervals. The blade (4) is made of an elastic material, and usually synthetic resin, such as polyurethane rubber, is used. In addition, the blades (4) are tilted at an angle (α) with respect to the belt (1) in several cases. The angle of inclination of the blade (4) is based on the angle of repose of the article, that is, the minimum angle of inclination at which the article can flow down along the inclination, and the angle of inclination is equal to or steeper than this angle of repose. It is set to be. In addition,
Since the angle of repose is determined by the absolute angle with respect to the vertical direction, if the inclination angle of the conveyor changes when the conveyor is installed, the absolute inclination angle of the blade (4) will change. Therefore, the belt (
In order to determine the mounting angle (α) of the blade (4) relative to 1), it must be determined by considering the installation angle of the conveyor. (6) is the casing of the conveyor, and (7) is its conveying wall. , the tip of the blade (4) moves while being in light contact with the conveying wall (4), and the inside of the article is pushed by the blade (4) and sent along this conveying wall (7). (8) is the lower bottom wall, which is formed into an arc shape, and the contents of the articles inputted from the article supply port (9) are temporarily retained on this F bottom wall (8), and the impellers (4) that arrive one after another are ) and are sent upward one by one as if being scraped by the blades (4). 00 is an article discharge port, which is pushed from the bottom by a blade (4),
When the article (Al) that has moved upward along the conveyance wall (7) reaches this discharge port 00, it flows out of the casing (6) by the inclination of the blade (4). It is detachably attached to the main body of 6), and when repairing or inspecting the conveyor, work is done by opening this rear wall 0υ. 0 is the left and right side walls. A slight gap is formed between the side wall Q and the blade (4), and when the blade (4) moves, the blade (4) comes into contact with the side wall O, increasing frictional resistance. Care has been taken to ensure that the articles φ) being transported do not fall in large quantities through this gap. Therefore, this gap should be appropriately determined depending on the length of the conveyor, the grain size of the conveyed article, etc. For example, when conveying grains, it is appropriate to set the gap to about 3 mm. There is still no day on this left and right side wall 0! J-(2) (3) The rotating shaft (13 (14)) is supported. However, the axis a of the lower pulley is supported in a fixed manner, but the rotating axis 03 of the upper pulley is supported by the side wall a. Since the shaft hole a formed in the hole is a long hole, it is supported in a state where it can be moved up and down.The reason why the shaft hole αO is made into a long hole is because the rotation shaft of the pulley can be moved. This is to adjust the tension of the belt (1) by changing the distance between the upper and lower (7) hooves (2) and (3). uQ is the number of driving members (= 1 cover, and the cross section is The outer surface of the two sides of the casing (6), i.e.
The back wall (11) and the left and right side walls are installed in such a manner that they cover the outer surfaces of the rear wall (11) and the left and right side walls. Goo above! Both ends of the rotating shaft Q3 of j-(2) are substantially supported by this cover. Therefore, this cover OQ can be opened by rotating it relative to the casing (6) with the rotating shaft 03 in the center and b as shown by the dashed line in FIG. 2, and the shaft hole a0 is a long hole. Casing the cover OQ by taking advantage of certain things (6)
It can be slid vertically by the length of the elongated hole. There is a Nupro lock at the end of the rotating shaft Q3.
7) is attached, and a chain wire is passed between it and the sprocket 09 attached to the motor 08).

Therefore, when the motor 0 rotates, the rotating shaft 0 rotates, and the pulley (2) is rotationally driven. Ql) is the motor mounting base plate, and this base plate υ is the cover〇f9
It is fixed by fitting it into the open end of the. @ is a screw for fixing the base plate. Furthermore, plywood? With υ attached, the cover M cannot rotate relative to the casing (6). However, even in this state, movement in two directions, that is, in the longitudinal direction of the casing (6) is possible.

@ is a position adjustment bolt, (C) is a bolt support member, the bolt (23 is screwed into the support member (C), and the support member (C) is
c) It is fixed to the casing (6). Therefore, when the pole 1-body 1 is rotated, the position of the tip of the bolt (C) moves, and the bottom surface of the base plate Qυ is pushed by the tip of this bolt, changing the position of the cover, that is, D! Since the position of j-(2) moves, the tension of be/l/ ) (1) can be adjusted. (A) is the chute board, and the lower pulley (
3) -] It is fixedly installed so that it is located on two sides,
To prevent conveyed articles falling from above from jumping between a pulley (3) and a belt (1). Particularly, when the conveyed object is a granular material such as grain, when the object is wound around the belt (1), the grain is crushed, and in the case of grain, the commercial value is reduced. Therefore, objects falling from above are caught by the inclined surface of the upper surface of the chute (C), and the objects are guided laterally along this slope, and the objects jump between the belt (1) and the pulley (3). It prevents

Next, the operation and handling of the conveyor will be explained. When the nozzle (2) is rotationally driven by the motor 0, the belt (1) circulates and the blades (4) attached to the belt (1) also circulate within the casing (6). Next, when the material to be transported is inputted from the supply port (9), the material falls onto the bottom wall (8) and remains there, and then is scraped off by the blades (4) that circulate one after another. They are pushed and transported one after the other. At this time, the feather (4
) has elasticity, so the tip of the blade (4) touches the lower bottom wall (8
) to bend moderately while in contact with the For this reason, the feather (4
) does not generate a large frictional force between the tip of the bottom wall (8) and the object is not damaged by being sandwiched between them, All items can be reliably transported without leaving any items behind. Also feathers (4)
When the blade (4) rises along the conveying wall (7), the tip of the blade (4) is properly pressed against the conveying wall due to the elasticity of the blade (4) and the deformation of the blade (1) at the blade attachment part. Since the conveyed article is in contact with the blade, the article is transported upward reliably and smoothly without the contents of the conveyed article falling out from between the tip of the blade and the wall surface, or being crushed by the tip of the blade, and Since the frictional force between the blade end and the wall surface is small, there is little frictional resistance during conveyance, and there is little wear and tear on the blade or wall surface. In this way, when the article is conveyed to the upper end of the conveyor and reaches the discharge port Q1, the inside of the article slides down under its own weight along the slope of the blade (4), and is discharged out of the machine from the discharge port Q1. Since the slope of the blade (4) is set to be greater than the angle of repose of the article, ejection is reliable and no article remains on the blade. In addition, since the discharge at this time is a tilted flow due to its own weight, and is not discharged by centrifugal force as in the case of discharge from a bucket elevator, there is little impact on the articles during discharge, and there is no possibility of causing granulation. Explain how to disassemble the device for repair or inspection. First of all,
Rotate the adjusting bolt (zlz)) in the direction to return the belt (1) to loosen the tension on the belt (1), then remove the screw (c) and attach the plywood QI) to the motor 08) as shown by the dashed line in Figure 2.
Remove the whole thing. As a result, the cover OQ becomes open,
Since it becomes rotatable, rotate the cover () with the rotation axis θ in the center 1b as shown by the dashed line in Fig. 2.
Next, the rear wall (1υ) is removed and repairs are performed from there.As described above, the blade type conveyor of the present invention, although it is a blade type, is capable of upward conveyance, and its slope ranges from gentle to steep. Furthermore, vertical upward conveyance is also possible.Therefore, compared to conventionally used packet elevators, the conveyor of the present invention has a simpler structure and can be manufactured at a lower cost as a device for upward conveyance. Moreover, the device can be made smaller, and is particularly suitable for conveying small quantities, and is convenient when incorporated into other devices.Furthermore, in the present invention, since the blades have elasticity and inclination, it is possible to reduce the size of the conveyed articles. can be conveyed reliably and smoothly, and even if the conveyed article is a granular material such as grain, no granules will be broken.

Furthermore, in the present invention, since the tips of the blades move along the lower bottom wall, the transported objects do not become infected with bacteria on the upper bottom wall soil, and all the transported objects can be reliably transported. This eliminates the need for cleaning and prevents pests caused by residue. Furthermore, the conveyor of the present invention is easy to assemble and disassemble, and operations such as repair and inspection can be performed easily.
