[0002]
[Prior art]
Conventionally, a main conveyor belt that is endless and has corrugated flanges on both sides in the width direction, and a space between the corrugated flanges on both sides of the main conveyor belt is closed and a space between the corrugated flanges is closed. A conveyor device is also known which comprises a cleat that is provided with cleats that divide the section at equal intervals in the length direction of the main transport belt and has an endless pressing belt.
[0003]
The conventional conveyor apparatus will be described with reference to FIGS. 2 to 4. Reference numeral 1 denotes an endless main conveying belt. The main conveying belt 1 has a corrugated flange 2 over its entire length on both sides in the width direction. , 2 are provided. 3 is a cleat 4 that closes the space between the corrugated flanges 2 and 2 on both sides of the main conveying belt 1 and partitions the space between the corrugated flanges 2 and 2 at equal intervals in the length direction of the main conveying belt 1. It is the endless holding belt which is provided with the surface.
[0004]
The main conveyor belt 1 includes a horizontal carry-in part 5, a vertical rise part 6, and a carry-out part 7 inclined upward at a gentle angle from the upper end of the rise part 6, and a head pulley 8 at the upper end and a tail pulley at the lower end. 9 is bridged in an endless ring shape, and an end roller 10 is supported for a change in the angle from the carrier-side carry-in portion 5 to the rising portion 6, and a change in the angle from the carrier-side rising portion 6 to the carry-out portion 7 is supported. The roller 11 has a disk pulley 12 for changing the angle from the unloading section 7 on the return side to the rising section 6, and a bend pulley 13 for changing the angle from the rising section 6 on the return side to the loading section 5. Carrier rollers 14 and 15 are respectively arranged on the inner side and the inner side of the rising portion 6, and the whole is almost Z-shaped.
[0005]
The pressing belt 3 is stretched endlessly between a head pulley 16 at the upper end and a tail pulley 17 at the lower end, and is pressed against the rising portion 6 of the main conveying belt 1 by a pressing roller 18. Note that the holding belt 3 corresponding to the angle change portion from the carry-in portion 5 to the rising portion 6 of the main conveyance belt 1 is received by the support roller 19, and the angle change from the rise portion 6 to the carry-out portion 7 of the main conveyance belt 1. The pressing belt 3 covering the outside of the main conveyance belt 1 at the inflection portion is received by the end rollers 20 at both sides in the width direction so that the pressing belt 3 is along the portion.
[0006]
In the conveyor apparatus having such a configuration, the main transport belt 1 is closed by the presser belt 3 from the joining portion of the main transport belt 1 and the presser belt 3 on the object to be transported placed on the carry-in part 5 of the main transport belt 1. At the same time, the cleat 4 provided on the presser belt 3 divides the main transport belt 1 at equal intervals in the length direction, and the main transport belt 1 and the presser belt 3 are driven in synchronization. In a state of being wrapped between the main conveyance belt 1 and the pressing belt 3, the rising portion 6 of the main conveyance belt 1 is conveyed upward. The unloading portion 7 at the upper end of the main conveyance belt 1 is not closed by the pressing belt 3, and the object to be conveyed is fed from the end of the unloading portion 7 of the main conveyance belt 1.
[0007]
In the above configuration, the main transport belt 1 has a beveled portion between the rising portion 6 on the carrier side and the carry-out portion 7, and the main transport belt 1 can be received by the support roller 11 at the beveled portion. Since the pressing belt 3 covering the outside of the main conveyance belt 1 at the bent portion is received by the end rollers 20 at both sides in the width direction, the pressing belt 3 is greatly increased toward the center in the width direction due to the tension. Deflection (see FIG. 4), whereby the corrugated flanges 2, 2 of the main transport belt 1 are pressed and deformed on both sides of the retainer belt 3, and the corrugated flanges 2, 2 of the main transport belt 1 are deformed. There was a problem that a gap was generated between the two and the conveyed object spilled out from the gap. In addition, the pressing belt 3 and the main conveying belt are curved at a large radius of the pressing belt 3 that covers the outside of the main conveying belt 1 at the bent portion and strongly contacts the outside of the main conveying belt 1 in a long range. 1 has a problem that the corrugated flanges 2 and 2 are worn quickly and have a short life.
[0008]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION The present invention solves such a problem, and prevents the object to be spilled from a bendable portion between the rising portion on the carrier side of the main conveyance belt and the carry-out portion, and also suppresses the holding belt and the main conveyance belt. The purpose of this is to reduce the wear of the corrugated flange and to prolong the service life.
[0009]
[Means for Solving the Problems]
In order to solve this problem, the present invention provides an endless main transport belt having a corrugated flange over its entire length on both surfaces in the width direction, and a space between the corrugated flanges on both sides of the main transport belt. And an endless holding belt provided with cleats on the surface for partitioning the space between the corrugated flanges at equal intervals in the length direction of the main conveyor belt, the main conveyor belt having a horizontal carry-in portion and The main transport belt includes a rising portion whose lower end is connected to the carry-in portion and a carry-out portion whose one end is connected to the upper end of the stand-up portion, and the main conveyor belt supports and rotates the angle changing portion between the rising portion and the carry-out portion on the carrier side. This two-stage bent state is formed by providing a lower bend portion and an upper bend portion formed by the body, and forming a short straight portion between the lower bend portion and the upper bend portion. Under the main conveyor belt A bendable belt and an upper bendable section are configured so that a presser belt extends along a straight line portion between the bendable section and the upper bendable section, and the presser belt is separated from the main conveying belt while keeping a straight line from the position of the upper beveled section. The gist is that it is configured.
[0010]
With this configuration, the main conveyor belt is bent in two locations, so that the tension acting on the holding belt along the belt is reduced, thereby reducing the amount of bending toward the center of the holding belt in the width direction. The belt can maintain a natural and normal state, preventing the object to be transported from the angled part between the rising part on the carrier side of the main transport belt and the unloading part from falling out, as well as the holding belt and main transport. The wear of the corrugated flange of the belt can be reduced, and the life can be extended.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings (FIG. 1). In the figure, the same members as those in the conventional example are denoted by the same reference numerals, and detailed description thereof is omitted.
[0012]
In FIG. 1, in the conveyor device of the present embodiment, the main conveyor belt 1 has two beveled portions 21, 21 and 22, between the rising portion 6 on the carrier side and the carry-out portion 7. It differs from the conventional example in that it is provided. That is, in the conveyor device of the present embodiment, the lower bend portion 21 is formed by a large number of support rollers 11a, and the upper bend portion 22 is formed by a large number of support rollers 11b. 21 is formed so that a short straight line portion 23 exists between the upper bendable portion 22 and a so-called two-stage folded state, and the lower bendable portion 21 and the upper bendable portion of the main conveyance belt 1 in the two-stage folded state are formed. The presser belt 3 is configured to follow the corner portion 22 and the linear portion 23 therebetween. More specifically, the lower bendable portion 21 of the main conveyor belt 1 is bent at an angle of about 30 degrees, and the upper bendable portion 22 is bent at an angle of about 50 degrees from the short straight portion immediately below. Further, the pressing belt 3 is configured to be separated from the main conveying belt 1 without being bent at the position of the upper bending portion 22 of the main conveying belt 1, and to be separated from the main conveying belt 1. The pressing belt 3 covering the outside of the main conveying belt 1 in 21 is received by end rollers 20 at both sides in the width direction. Since other configurations are the same as those of the conventional example, detailed description thereof is omitted.
[0013]
In the above-described configuration, the main conveying belt 1 is divided into two locations and the angle is changed, so that the tension acting on the pressing belt 3 along this is reduced, thereby reducing the amount of bending of the pressing belt 3 toward the center in the width direction. Thus, the presser belt 3 can maintain a substantially natural normal state, and the wave-shaped flanges of the main transport belt are pressed and deformed on both sides of the presser belt as in the conventional example, and the presser belt and the main transport belt are deformed. It solves the problem of the fall of the object to be conveyed due to a gap between the corrugated flange and the problem that the corrugated flange of the holding belt and main conveyor belt wears quickly and has a short life. is there.
[0014]
In the above embodiment, the lower bending portion 21 of the main conveyance belt 1 is formed by a large number of support rollers 11a, and the upper bending portion 22 is also formed by a large number of support rollers 11b. The portion 22 may be formed by a single thick bend pulley. That is, the upper bendable portion 22 may be formed by a support rotating body such as a large number of support rollers 11b or a single bend pulley.
[0015]
【The invention's effect】
As described above, according to the present invention, since the main conveyance belt is divided into two portions and bent, the tension acting on the pressing belt along the main conveying belt is reduced, thereby bending toward the center in the width direction of the pressing belt. As the amount is reduced, the holding belt can maintain a substantially natural normal state, and prevents the spilled material from being transported from the bendable portion between the rising portion on the carrier side of the main transport belt and the carry-out portion. It is possible to reduce the wear of the corrugated flange of the presser belt and the main transport belt and to extend the service life.
