Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a conveying device using the principle of a linear motor for conveying machined non-magnetic conductive metal products to the next process without mechanical contact. It is related to.

[Prior art]

In general, machined non-magnetic conductive metals used as product materials or products (hereinafter referred to as "products, etc.") are washed, etc., and then transferred to the next process using some mechanical conveyance means, such as a belt conveyor. It is being transported.

[Problem that the invention seeks to solve]

However, with conventional technology, machined products, etc., not only pick up dirt when they pass through a conveyance device, but also cause dirt attached to the product, etc., to be transferred to the conveyance device, or this dirt to be attached to other products, etc. There was a risk of contamination. Further, when products, etc. were transported using the contact type conveyance means, problems such as scratches on the surface of the products, etc. occurred. Furthermore, mechanical conveyance means such as belt conveyors are limited in conveyance speed in order to ensure stable conveyance of products, etc., and the conveyance speed is slow, which may lead to a decrease in efficiency.

The purpose of the present invention is to eliminate opportunities for contamination of products, etc. by transporting products, etc. from one process to the next process without mechanical contact, and to improve transport efficiency. .

[Means for solving problems]

When transporting machined products, etc., the present invention provides
This is used as a secondary member for a linear motor, a moving magnetic field is applied to it, and a foaming liquid is interposed between the two, so that the product to be transported can be transported while floating on the foaming liquid. This is the summary.

One specific example of the configuration of the present invention will be described below. Figure 1 is a cross-sectional view, and Figure 2 is a perspective view. In each figure, 1 is a gutter made of a non-magnetic material, preferably a non-metallic material, but with high electrical resistance such as stainless steel. You can also use your body. Reference numeral 2 denotes a moving magnetic field generator, which serves as the primary side of a linear motor, and is disposed facing the bottom surface of the gutter 1 at appropriate intervals. Reference numeral 3 denotes a foaming liquid ejecting device, which is disposed along the guide path 1a of the gutter 1 that guides a product, etc. as a conveyed object made of a non-magnetic conductor, which will be described later, and sprays the foaming liquid toward the product, etc. A spout opening 3a is formed. Reference numeral 4 denotes a foamable liquid supply port, which exits from an appropriate location of the jetting device 3 to the outside from the lower side of the gutter 1. This foaming liquid supply port 4
The number varies depending on the length of the gutter 1, especially for the short gutter 1.
In the case of , it is also possible to perform the role with one piece. Also,
The foaming liquid ejecting device 3 connected to each foaming liquid supply port 4 may be integrated or may be divided according to each supply port 4. 5 is a foaming liquid;
After being supplied from the supply port 4, the opening 3 of the ejection device 3
It squirts upwards from a and generates strong bubbles. 6 is a transported product made of a non-magnetic conductor,
It is sent into the guide path 1a.

[Effect]

In the above configuration, a non-magnetic conductive product etc. 6 processed by a mechanism not shown is connected to the guide path 1a of the gutter 1.
When the foaming liquid is supplied, the foaming liquid is already supplied from the foaming liquid supply port 4, and the foaming liquid 5 is jetted out from the opening 3a of the jetting device 3, and bubbles are generated. Along with this, the bubbles act as an air bearing and the product etc. 6 floats up. In this state, when the moving magnetic field generating device 2 generates a moving magnetic field in the direction of arrow A, the products etc. are conveyed in the direction of arrow A by the principle of a so-called linear motor in which the products etc. 6 serve as a secondary conductor. In this way, products etc. are transported to the next process. In this process, the foamable liquid 5 is recovered through the return passage 1b.

Note that the foamable liquid 5 may be recovered through the surface forming the air bearing of the ejection device 3 without providing the return passage 1b. Furthermore, if the foaming liquid 5 is used as a cleaning liquid, during the process in which the non-magnetic conductive product, etc. 6 to be transported is transported on the jetting device 3 using the foamy foaming liquid as an air bearing,
Products, etc. are washed, and an independent washing device can be omitted. That is, it is possible to wash the non-magnetic conductive product 6 to be transported and further prevent the re-adhesion of dirt by incorporating the dirt into the foam.

〔effect〕

As described above, the conveying device using the principle of the linear motor according to the present invention uses a foaming liquid jetting device as a means for transporting a product made of a non-magnetic conductive material to the next process. At the same time, the moving magnetic field from the moving magnetic field generator and the eddy current induced in the product act as a so-called linear motor to transport the product. It is something. Therefore, since no mechanical contact is involved in the transfer process of products, etc., there is no chance of dirt being transferred to or from the products, etc., and the conveyance speed of products, etc. can be increased compared to conventional mechanical conveyors. Conveyance efficiency can be improved.
