Abstract

PURPOSE:To smoothly and cost-effectively transport articles, by constituting a chute for transferring articles by the sliding motion due to the own weight thereof with longsize bars for supporting the bottom and sides thereof. CONSTITUTION:The side faces of a rectangular parallelepiped article 2 to be transported are supported by side rods 3 composed of respective two right and two left long bars and also the bottom thereof is supported by a bottom rod 4 composed of one long round bar, so as to constitute a chute 1. These rods 3, 4 are fixed in the insides of brackets having the U-shaped sections, fitted at every appropriate distance in the axial direction and made so as to form tapers 6 toward their fronts. Since the article to be transported and the bars are always in line-contact, water, oil, dust, etc., this contact is hardly influenced by and it is easy to clean and it can be always kept in a stable transport condition. And since the front end of the round bar is tapered, the articles to be transported are smoothly transferred to another chute at the joint.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article transport chute having an inclined path for moving an article by its own weight.

[0002]

2. Description of the Related Art As a conveying means for transferring an article from one point to another without using power, a ramp type article conveying chute having a height difference between a start end and an end of a feeding path is known. There is.

In the case where an article is conveyed by a conveying device utilizing the sliding motion of the article itself due to its own weight, if a simple groove-shaped chute as shown in FIG. 3 is used, the article will be spherical or circular. Although it does not cause any problems, in the case of a relatively lightweight rectangular parallelepiped object, the mutual contact area between the transported object and the chute is large, so smooth movement is impeded by the adhesion of water, oil, dust, etc. It tends to happen.

As shown in FIG. 4, an example is known in which a guide strip is provided on the inner surface of the guide wall to reduce the contact area with the object to be conveyed. However, since the guide wall is closed, the object to be conveyed is conveyed. It is difficult to visually check the running state of the object, the processing cost of the guide wall tends to be high, and maintenance of the inner surface of the guide wall is difficult.

Although there is a chute that moves an object to be conveyed by applying vibration in a certain direction to the chute using a vibration exciter, the increase in initial cost and running cost due to the vibration exciter is inevitable.

[0006]

SUMMARY OF THE INVENTION The present invention has been devised to solve the above-mentioned disadvantages of the prior art.
Its main purpose is to provide an article transfer chute that can realize smooth transfer at low cost.

[0007]

According to the present invention, such an object is to provide a chute for moving the article by a sliding motion due to the weight of the article itself to support a chute for supporting the bottom surface and the side surface of the article. This is achieved by constructing a rod-shaped member having a length. Particularly, it is preferable that the end of the rod-shaped member is tapered.

[0008]

As described above, by forming the chute with the round bar or the pipe material, the contact with the article becomes a line contact, so that the transport resistance can be remarkably reduced. In addition, it is possible to easily visually check the transportation state of the article through the gap between the rod-shaped materials. In addition to this, by making the end portion tapered, it is possible to prevent the connection portion from being caught.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described in detail below with reference to specific embodiments shown in the accompanying drawings.

FIG. 1 partially illustrates a chute constructed in accordance with the present invention. This chute 1 has a side rod 3 formed of two long round rods on each of the left and right sides of a transported object 2 having a rectangular parallelepiped shape, and a bottom rod 4 formed of one long round rod at the bottom surface. It is supposed to support. As shown in FIG. 2 as well, each of these rods 3 and 4 is fixed to the inner surface of a bracket 5 having a U-shaped cross section which is provided at an appropriate interval in the axial direction, and is tapered at each end thereof. Taper 6 is formed.

FIG. 2 shows the structure of the distribution unit 7 of the chute 1. The distribution unit 7 rotates between a first position (shown by an imaginary line) coaxial with the bottom rod 4 and a second position where the free end is swung upward as shown by a solid line in FIG. The distribution rod 8 is free and is driven by, for example, an air cylinder. If the sorting rod 8 is placed in the first position, the transported object 2 goes straight on the upper chute 1a in FIG. 2, and if it is placed in the second position, the transported object 2 moves to the lower chute 1b. It will fall toward. In this way, by selectively setting the position of the sorting rod 8 by a separate control signal,
It is possible to easily sort the transported objects 2.

[0012]

As described above, according to the present invention,
Since the transported object and the rod-shaped material are always in line contact,
In addition to being easily affected by adhesion of water, oil, dust, etc., and being easy to clean, it is possible to always maintain a stable transport state. In addition, since it is possible to smoothly transfer the transported object at the connection portion by simply tapering the end portion of the round bar material, it is not necessary to perform highly accurate positioning, and the assembly is easy. It is possible to flexibly deal with changes in layout, expansion, and so on. Moreover, since the round bars can be installed with a gap in between, it is possible to easily visually check the behavior of the transported object. It is easy to repair because it is obtained. In addition, since it can be manufactured very easily by combining round bars or pipes, the manufacturing cost is low and high maintainability can be obtained.
