Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vertical belt conveyor device that conveys an object such as earth and sand above ground or above ground or above ground.

[0002]

[Prior art]

 Generally, the vertical belt conveyor device is useful for transporting construction sand, gravel, etc. from the ground to a higher place, or for transporting soil to the ground for underground excavation.

As shown in FIG. 5, the conventional vertical belt conveyor device has an endless conveyor belt 3 stretched between a drive pulley 1 arranged above and a tail pulley 2 arranged below, An object to be conveyed 5, such as earth and sand, is placed on the horizontal shaft 4 provided on the outside of the belt 3, and is conveyed upward and then discharged. In this conventional example, horizontal portions are provided above and below. In the figure, 6 is an upper base, 7 is a lower base, 8 is a disc roller, and 9 is an excavation hole.

In the vertical belt conveyor device having the above-described configuration, the vertical traveling portion of the conveyor belt 3 is considerably long, and the number of the supporting rollers 10 is small in this vertical traveling portion. Therefore, the vertical traveling portion of the conveyor belt 3 has a curling motion. This may cause the transported object to drop during transportation, which is dangerous and reduces the transportation effect. For this reason, as shown in the figure, the anti-ravel belt 10 is in contact with the vertical traveling portion of the conveyor belt 3 on the object-conveying side.

[0005]

[Problems to be solved by the device]

 In the vertical belt conveyer device having the above-described configuration, the belt 10 for curling is used to prevent the conveyor belt 3 from being squeezed, and since the transported object protruding from the horizontal shaft 4 is held down, the risk of the transported object falling is reduced. However, the anti-rattle belt 10 rubs against the transported object and the conveyor belt 3 to generate noise, and the anti-rattle belt 10 is worn by the rubbing. 4 and the flexible side plate 15 are worn.

The present invention has been made in consideration of the above conventional problems, and an object of the present invention is to provide a vertical belt conveyor device which is low in noise and safely conveys an object to be conveyed.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the vertical belt conveyor device of the present invention comprises an endless conveyor belt stretched between a drive pulley arranged above and a tail pulley arranged below, whereby the conveyor belt runs vertically. Section or inclined traveling section, and the anti-raising belts are arranged facing each other with a small gap on the conveyed object side, and the anti-raising belt is configured endlessly and is designed to run synchronously with the conveyor belt. The belt conveyor system will be used.

[0008]

[Action]

 In the vertical belt conveyor device having the above-mentioned configuration, the conveyor belt is prevented from being swung by the anti-raising belt, and the transported object protruding from the lateral side of the conveyor belt is pressed by the anti-causing belt, and therefore the transported object is prevented. In addition, there is little drop, and the anti-raising belt does not contact the conveyor belt and does not generate noise due to synchronous running, and the two belts are minimally worn due to rubbing between the anti-raising belt and the conveyor belt. It is suppressed to the limit.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. In the figure, 11 is a drive pulley, 12 is a tail pulley, 13 is an endless conveyor belt, 14 is a horizontal shaft integrally provided on the outside of the conveyor belt 13, and 15 is an outer side portion of the conveyor belt 13. A flexible side plate, 16 is an upper base, 17 is a lower base, and 18 is a disk roller. These are configured in the same manner as the configuration of the conventional example described above, and therefore description thereof is omitted.

A feature of this embodiment is the arrangement of the anti-rattle belt 19. That is, the anti-raising belt 19 is configured to be endless, and is stretched between the second drive roller 20 and the tail pulley 21, and one surface of the anti-raising belt 19 conveys an object to be conveyed in a vertical traveling portion of the conveyor belt 13. It is placed so as to face each other with a gap of 10 to 30 mm. The width of the anti-raising belt 19 is made substantially equal to the width of the conveyor belt 13.

In the above-mentioned configuration, the conveyor belt 13 carries the object 20 to be conveyed on the horizontal shaft 14, and is conveyed upward by the traveling of the conveyor belt 13. When the conveyor belt 13 reaches the vertical traveling portion, the anti-raising belt 19 is provided so as to face the anti-raising belt 19. Therefore, when the conveyor belt 13 tilts, the motion is prevented. Further, the transported object 20 is prevented from falling to the outside by the anti-belt belt 19. Here, the transported object 20 protruding from the horizontal shaft 14 comes into contact with the anti-raising belt 19, but since the anti-raising belt 19 runs in synchronization with the conveyor belt 13, the anti-raising belt 19 is used. It is conveyed upward while being held down.

In the above embodiment, the conveyor belt 13 has horizontal portions at the upper and lower portions, but this horizontal portion may be omitted, and the vertical traveling portion may be inclined. Furthermore, the shapes of the base, the lateral walls of the conveyor belt, the side walls, etc. are not limited to those shown in the drawings, and any shape may be used as long as it has its function.

[0013]

[Effect of device]

 As is clear from the description of the above embodiments, in the vertical belt conveyor device of the present invention, the anti-raising belt is arranged oppositely with a small gap on the conveying side of the conveyor belt in the vertical or inclined traveling portion. Since the anti-raising belt is made to run in synchronization with the conveyor belt, the anti-raising belt can be prevented and the objects to be conveyed can be prevented from falling.Because the anti-raising belt does not rub against the conveyor belt, noise and noise are generated. It has no practical wear and is of great practical value.
