JP-A-7-285630

In the conveyor belt disclosed in Patent Document 1, an endless belt is wound around a pair of conveyor rollers to run. For this reason, it is necessary to make the conveyor belt flat in the section near the conveyor roller, and the both ends of the width direction cannot be erected, and the conveyor belt is gradually erected outside this section, so it is called conveyance. From a viewpoint, the traveling section during the standing is useless.
For the same reason, as the conveyance end is approached, the standing part near the edge of the conveyor belt is gradually returned to the flat shape, and in this section, the conveyor belt against the spillage and the side of the conveyed goods. There is a problem that the feeding action of is lost.

  The present invention eliminates the problems associated with the prior art described above, and can hold the standing portion at all of the conveyor belt from the start end to the end, or at least at the start or end of the conveyor belt. It is an object of the present invention to provide a transport conveyor that has no useless space that is not involved in transport, and that does not have the problem of spilling or eliminating the belt feeding action on the side of transported goods.

In the present invention, the edge in the width direction of the endless belt-shaped conveyor belt wound around a pair of conveyor rollers provided in the front and rear of the traveling direction is uniformly raised together with the conveyor roller over the entire region in the traveling direction. and then, the folding is a fold portion at least during standing of the endless belt conveyor belt formed of a flexible material having high elongation than bellows or other portion was orthogonal to the folded portion of the conveyor belt in the running direction The above-mentioned object is achieved by a transport conveyor characterized by being positioned on substantially the same plane.

Furthermore, in the present invention, the edge in the width direction of the endless belt-shaped conveyor belt wound around a pair of conveyor rollers provided before and after the running direction is at least at the start end or the end of the running direction. wherein and is erected with the conveyor rollers, endless the fold is a fold portion at least during standing of the belt conveyor belt formed of a high flexibility material elongation from bellows or other portion, the side of the conveyor is raised The above object can also be achieved by a conveyor that is characterized in that the folded portion of the belt is positioned on substantially the same plane orthogonal to the running direction.

Here, the folded portion of the endless belt-like conveyor belt may be formed in a bellows shape, or the folded portion may be formed of a flexible material having a higher elongation rate than other portions of the conveyor.

In this case, the endless belt formed of a flexible material having a higher elongation rate than that of a separate bellows or other portion may be joined to the bent portion of the endless belt-like conveyor belt.

  Further, in the present invention, both edge portions in the width direction of the endless belt-like conveyor belt may be erected to make the belt cross-section substantially upward, or one place in the width direction of the endless belt-like conveyor belt may be provided. It is good also as a V-shaped cross section by bending, and also it is good also as a polygonal cross section by bending several places of the width direction of an endless belt-like conveyor belt.

  Furthermore, in the present invention, an endless belt-like conveyor belt is wound around a pair of conveyor rollers provided at the front and rear in the traveling direction, and one of the conveyor rollers is driven by a motor built in the conveyor roller. It is preferable.

  Further, the standing straight portion of the endless belt-like conveyor belt is wound around a pair of conveyor rollers provided in the front and rear of the running direction, and a motor-equipped conveyor roller is provided in the standing straight portion, and the standing straight portion A device for transmitting power from the conveyor roller with a built-in motor to the conveyor roller of another adjacent linear portion may be provided. In this case, the power transmission device can be a constant velocity universal joint, a pair of bevel gears, or the like.

  According to the present invention, the vicinity of the edge in the width direction of the conveyor belt is uniformly erected over the entire region in the traveling direction, and the final end of the conveyor belt is transferred from the starting end portion without being dislodged in a granular, powdery, or softly conveyed product. Can be transported to the end.

  Further, in the present invention, since the side surface of the conveyed product is in contact with the upright portion of the conveyor belt at at least one of the start end portion and the end portion in the traveling direction, it is reliably conveyed also at the start end portion or the end portion.

  According to the present invention, in the case of a conveyed product containing liquid, since the liquid does not flow down from the side of the conveyor belt, the conveyed product containing the liquid does not adhere to the back side of the belt, a roller or the like, and is hygienic.

  According to the present invention, since the bent portion of the conveyor belt covers the conductive device between the rollers, there is no inflow and biting of the conveyed object, and safety is high.

  According to the present invention, the entire length of the conveyor can be shortened, so that the cost is low and the installation area is small.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings illustrating embodiments of the present invention. FIG. 1 is a perspective view of an embodiment of a conveyor according to the present invention.

As shown in FIG. 1, a pair of conveyor rollers 3 are provided at the front and rear in the traveling direction, and an endless belt-like conveyor belt 1 formed integrally is wound around the pair of conveyor rollers 3 and folded from the folding portion 2. It bends and the edge part of the width direction of the conveyor belt 1 is stood up uniformly over the whole area of a running direction. A portion 2 of the endless belt-like conveyor belt 1 that is bent at least when standing is made of a flexible material such as a polymer material having a higher elongation rate than other portions, or a bellows-like shape so as to be stretchable. As shown in FIGS. 1 and 2, the folded portion of the conveyor belt 1 is positioned on substantially the same plane orthogonal to the traveling direction.

  FIG. 2 is a plan view showing a state in which the conveyor shown in FIG. 1 is partially peeled off, and is a development view in which the left half of the drawing is returned to the horizontal position by the standing angle. Moreover, FIG. 3 is AA sectional drawing of the state which peeled off the conveyance conveyor shown in FIG. 2 partially.

  In FIG. 2, a pair of side plates 8, 8 are arranged in the vicinity of both ends of the horizontal portion of the conveyor belt 1 and the standing portions on both sides, and the side plates 8, 8 are connected to bolts 10 by appropriately connecting the connecting rods 9, 9. By tightening at 10, three sets of frame bodies are formed, that is, a horizontal portion and both side standing portions. These frames are appropriately provided with a receiving plate for receiving the back side of the conveyor belt 1 and a guide roller (both not shown). Further, the arrangement of the receiving plate and the guide roller can also be carried so that the vicinity of the edge of the conveyor belt is pressed inward to surround the conveyed product being conveyed.

  These three sets of frames are connected by several connecting elbows 11 and 11 having a predetermined angle to form an integrally constructed conveyor frame 7 that is uniformly raised over the entire traveling direction. To do.

  As shown in FIG. 3, fixing stays 12 and 12 are detachably attached to side plates 8 and 8 positioned on both outer sides with bolts or the like as appropriate, and the conveyor frame 7 is fixed in place. In this way, the conveyor of the present invention can be easily assembled.

  A well-known motor pulley 3a having a built-in motor is used as a driving roller for the horizontal straight portion of the conveyor belt 1 and the standing straight portions on both sides. The roller 3 on the opposite side of the motor pulley 3a is an idler roller 3b, and both shaft ends of the roller 3b are supported by air cylinders 13 and 13 so that the conveyor belt 1 can be tensioned.

  When removing the conveyor belt 1 having the above configuration, first, the idler roller 3b is moved by the air cylinder 13 to loosen the conveyor belt 1. Next, any one of the fixed stays 12 is removed, and the conveyor belt 1 is pulled out from the removed side.

  The assembly of the conveyor belt 1 is in the reverse order to the case of removing the conveyor belt 1 described above. That is, after the conveyor belt 1 is mounted from the side where the fixed stay 12 is removed, the fixed stay 12 is fixed, and the idler roller 3b is moved by the air cylinder 13 to tension the conveyor belt 1.

  As a method for transmitting power to the rollers 3, there is a method in which each of the above-described rollers 3 is used as a motor pulley 3a, and each driving roller 3 is rotated individually. In addition to this, the motor pulley 3a has only one standing straight portion, and the drive-side roller shaft of the horizontal straight portion and one standing straight portion is sequentially transmitted by interposing a transmission element described later. There is a way to go.

  Furthermore, for example, one of the conveyor rollers 3a located outside in FIG. 2 is a roller 3 with a shaft, and both ends of the shaft are supported by bearings provided on the side plates 8 and 8 so that the outside of the conveyor roller 3 is outside. External power (power from a motor, etc.) is input from the shaft end of the shaft through a transmission mechanism as appropriate, and the following power transmission element is interposed between the inner shaft end and the shaft end of another adjacent conveyor roller. You can develop them in any combination.

  Examples of the power transmission element between the roller shaft ends include those using a pair of bevel gears 5 and 5 'shown in FIG. 4, and those connected by a constant velocity universal joint 6 shown in FIG.

  6 and 7 are similar to the configuration of the embodiment shown in FIGS. 1, 2 and 3, and the bending portion is increased or decreased. In the embodiment shown in FIGS. The both edges of the conveyor belt 1 in the width direction were erected to make the conveyor belt cross-section substantially upward. On the other hand, in FIG. 6, one portion in the width direction of the conveyor belt is bent to have a V-shaped cross section, and in FIG. 7, a plurality of portions in the width direction of the conveyor belt are bent to form a polygonal cross section. It is said.

In the above embodiment, the bent portion of the integrally formed endless belt-like conveyor belt is formed in a bellows shape, or is formed of a flexible material having a higher elongation rate than the other portions. However, an endless belt formed of a flexible material having a higher elongation rate than a separate bellows or other portion may be joined to a bent portion of an endless belt-like conveyor belt to be integrated. In this way, the individual parts of the conveyor belt can be made individually and joined together later, making manufacture easier.

Furthermore, in the said Example, the edge part vicinity of the width direction of an endless belt-shaped conveyor belt was stood up uniformly over the whole region of a running direction. However, in the present invention, the vicinity of the edge in the width direction of the conveyor belt may be raised at at least one of the start end and the end end in the running direction. Such an embodiment is shown in FIG. In the embodiment of FIG. 8, the vicinity of the edge of the conveyor belt 1 in the width direction is raised at the start end (when the conveyor belt is moved in the direction of the solid arrow) to prevent spillage of the conveyed product at the start end, or Standing up at the terminal end (when the conveyor belt is moved in the direction of the broken line arrow) prevents spillage of the conveyed product at the terminal end. As is apparent from FIG. 8, in the embodiment shown in FIG. 8, the folded portion of the conveyor belt 1 is located on substantially the same plane orthogonal to the traveling direction.

It is a perspective view of one Example of the conveyance conveyor which concerns on this invention. It is a top view of the state which peeled off the conveyance conveyor shown in FIG. 1, and it is a development view which made the left half returned to the horizontal by the standing angle toward drawing.
