Abstract

(57) [Summary] [Purpose] To enable lifting and conveying of cylindrical metal fittings without providing a large number of crosspieces on a conveyor belt. [Structure] The conveyor belt 10 is provided in an inclined state, and a large number of chains 12 are lined up along the width direction at the lower end portion of the conveyor belt 10 with the lower end hanging down. 1
The cylindrical metal fittings 18 are brought into contact with the upper surface of the belt 10 over a predetermined length in the conveyance direction of the chain 12, and the direction of the cylindrical metal fittings 18 is changed by the irregular movement of the chains 12, so that it is raised as the belt 10 moves.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea is based on a belt controller that transports rolling objects such as cylindrical and cylindrical objects from below to above. Regarding the conveyor device.

0002 [Problems to be solved by conventional techniques and ideas] When conveying cylindrical objects or cylindrical objects from bottom to top using a belt conveyor device, Because these conveyed items rotate on the belt and cannot be conveyed smoothly, it is usually 3, a plurality of bars 102 are provided on the belt 100 at a predetermined pitch. The articles 104 are received and conveyed by the crosspieces 102.

0003 In this belt conveyor device, a belt is generally used as shown in Fig. 4. A side plate 106 is provided above the crosspiece 102 at both ends in the width direction of the conveyed object 10. 4 from falling from the ends of the belt 100 in the width direction. 102, it goes without saying that the side plate 106 should be in almost contact with the top surface of the belt 100. Since the conveyed object 104 on the belt 100 cannot hang down to the position where it is The end of the belt 100 in the width direction passes under the side plate 106 between the belts 102 and 102. This causes the inconvenience of falling further downward.

0004 In addition, since there is some gap between the side plate 106 and the crosspiece 102, the belt 10 0 with a plate-like object 108 placed on it together with a rolling object such as a cylindrical object or a cylindrical object, or When conveying separately from them, these plate-like objects 108 are connected to the crosspiece 102 and side plate 106 The fall prevention plate may be caught between the crosspiece 102 and the lower end of the belt 100. 110 (see FIG. 3), and further between the crosspiece 102 at the upper end of the belt 100 and the receiver 112. This causes the inconvenience of being caught between the two.

[0005] In addition to this, when such a crosspiece 102 is provided, the crosspiece 102 may change its shape during the period of use. It is said that maintenance work is troublesome because it causes collapse and wear and tear. Other problems also arise.

[0006]

[Means to solve the problem]

This invention was developed to solve these problems, and its gist is as follows: A cylindrical or columnar object is placed on a conveyor belt that is tilted up and down. In a belt conveyor device that conveys the conveyed object from the bottom to the top, the bottom of the belt A large number of chains are lined up along the width of the end portion with almost no gaps, and the lower end is At the same time, the lower ends of the belts are made to hang down over a predetermined length in the conveying direction of the belt. The reason is that the belt is made to come into contact with the upper surface of the belt.

[0007] [Effects of actions and ideas] In the device of this invention, if a rolling object such as a cylindrical object or columnar object is placed on the belt, , they are blocked by a number of blind-like chains lined up at the bottom end of the belt. become trapped.

[0008] In this state, when the belt moves upward from the bottom, the axial direction of the conveyed object If the direction matches the conveying direction of the belt, the belt will move without rotating. However, many other items are transported upward as the belt moves. Performs a rotational movement and is not carried upwards.

[0009] On the other hand, many chains with their lower ends touching the top surface of the belt are The lower end lifts up and returns due to the movement, and this repeats, as if dancing. Perform irregular movements.

0010 Due to this movement, the conveyance that is blocked by these chains The orientation of the object gradually changes, and eventually the vertical direction, that is, the axial direction becomes the bell. The conveyed object facing the conveyance direction of the belt is conveyed upward as the belt moves. wife The conveyed object, which is in a random state, is corrected in direction by the movement of the lower end of the chain. It is gradually carried upwards.

[0011] According to this device, there is no need to provide the above-mentioned crosspiece on the belt. The above-mentioned problems caused by the arrangement of the crosspieces can be solved.

【Example】

Next, we will explain an example of the present invention when transporting a cylindrical metal fitting (hereinafter referred to as a workpiece). will be explained in detail based on the drawings as an example. In FIG. 1, 10 is a belt in a conveyor device 11, which is arranged in an inclined state. It is set up. This belt 10 has a cone-like shape from the ends in the width direction toward the center. It has a concave cross section.

[0013] 12 are chains arranged in the width direction with almost no gaps at the lower end of the belt 10 The upper end is supported by a support member 14. Also, their lower end sides are self-contained. It hangs down due to the weight, and each lower end extends over a predetermined length in the longitudinal direction of the belt 10. is brought into contact with the upper surface of the belt 10.

[0014] 16 is a back plate placed after the chain 12, and its lower end is above the belt. It extends to a position where it almost touches the surface.

[0015] In the case of the belt conveyor device 11 of this example, as shown in FIG. Initially, the lower ends of the chains 12 arranged on the belt 10 extend over a predetermined length. The belt 10 is in contact with the surface, and in this state, the belt 10 moves upward in the direction of the arrow in the figure. As shown in (B) and (C), the lower end of the chain 12 is held by the belt 10. being lifted upwards.

[0016] Along with this, the contact length between the chain 12 and the belt 10 decreases, and When the chain 12 reaches the position shown in FIG. and return to the original position vigorously. The returned chain 12 continues to move the belt 10 causes the lower end to move upward again in the order of (A) → (B) → (C), and almost When it was stretched out to its full extent, it was brought back again with great force.

[0017] The chain 12 repeats this movement. At that time, the wire placed on the chain 12 The chain 18 uses its own weight to increase the frictional force between the lower end of the chain 12 and the upper surface of the belt 10. and encourage the above-mentioned movements.

[0018] Now, when the workpiece 18 is placed on the lower end of the belt 12, most of the workpiece 18 is placed on the lower end of the belt 12. It rotates as it moves, and is not transported upward even when the belt 10 moves. .

[0019] However, the chain 12 does not move as described above, or irregularly as if dancing. In order to cause regular motion, the direction of the workpiece 18 is gradually changed during the process. As shown in FIG. 2(C), the belt 10 reach. The workpiece 18 facing the same direction will not rotate and move as the belt 10 moves. Both are lifted upwards.

[0020] That is, in this device, a large number of chains 12 act as direction correcting members for the workpiece 18. A large number of works 18 dropped onto the belt 10 are gradually carried upwards. Ku.

[0021] Although the embodiments of the present invention have been described in detail above, this is merely an example. For example, in the above example, the belt 10 has a concave cross section, but it can be changed to a flat shape. In addition to the above-mentioned cylinder, it is also possible to use rectangular cylinders, cylinders, and other shapes. Also applicable to conveying workpieces that have a rotatable direction and a non-rotational direction. This invention is within the knowledge of a person skilled in the art to the extent that it does not depart from the spirit of the invention, such as that it is possible. It can be configured with various changes based on the above.
