Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] When a ceramic substrate is conveyed by a conveyor and blasted in a blasting chamber, the present invention applies to This invention relates to a device for inverting a ceramic substrate that inverts the ceramic substrate so that it selectively follows the inclined portion of the substrate.

[Prior art 1] Conventionally, a V-shaped substrate support section is provided on the outer periphery of a conveyor that passes through a blast chamber, and a ceramic substrate is placed on one inclined section of this V-shaped substrate support section. The ceramic substrate is supported in an inclined state, and one surface of the ceramic substrate is blasted by jetting blasting material from a blasting material jetting nozzle installed in the blasting chamber. Reversing air is applied to the ceramic substrate that was being supported to invert the ceramic substrate and support it on the other inclined part of the V-shaped substrate support part, and then the blasting material is jetted from the blasting material jetting nozzle in the blasting chamber. Then, the other surface of the ceramic substrate is blasted.

[Problems to be Solved by the Invention] In the case of the above-mentioned conventional example, inverting air is not used to align the ceramic substrate along one slope of the V-shaped substrate support and to align the ceramic substrate along the other slope of the V-shaped substrate support. It ejects and flips the ceramic substrate, but it is not related to the size of the ceramic substrate (,
It blows out air at a constant pressure <4Kg/cm2) and turns over.

By the way, there are various types of ceramic substrates with different sizes, and if the size of the ceramic substrate is small, there is a problem that the air hits the ceramic substrate with more force than necessary, causing the ceramic substrate to crack. If it is lower, there is a problem that it will not be inverted if the ceramic substrate is large. Therefore, depending on the size of the ceramic substrate, the position of the air jet nozzle must be adjusted to hit the center of the ceramic substrate (in the present invention, this is the position that is most likely to turn over when air is applied to the ceramic substrate), or the air pressure must be adjusted. There is a problem of having to make adjustments.

The present invention has been made in view of the above points, and an object of the present invention is to provide a reversing device for ceramic substrates that can reliably reverse ceramic substrates of different sizes without any adverse effects.

[Means for Solving the Problems 1] In order to achieve the above object, the inverting device for ceramic substrates of the present invention is provided with a substrate support portion 5 shaped like a 7 on the outer periphery of a conveyor 2 passing through a blasting chamber 9. The ceramic substrate 1 is placed along one inclined part 8 of the substrate support part 5 having a shape of 7, and a blasting agent is applied to one surface of the ceramic substrate 1 by spraying the material. In the blast processing apparatus, the ceramic substrate 1 is placed along one inclined part 5 of the substrate supporting part 5 in the shape of a letter 7, and blasting material is ejected onto the other surface of the ceramic substrate 1 for blasting. A reversing air jet nozzle 11 that is reversed in order to align the substrate along the other inclined portion 8 is disposed on the side of the substrate support portion 5, and a plurality of reversing air jet nozzles 11 are arranged above and below. No. 3-4- Composed of nozzle parts 11a, 1lb, and 11c, suitable air nozzle parts 11a and 11c are arranged according to the size of the ceramic substrate 1.
It is characterized by being configured to blow out air from the lb and lie.

[Operation] When the size of the ceramic substrate 1 is small, air is ejected from the air nozzle part 11a located below to hit the center of the ceramic substrate 1, and the ceramic substrate 1 is turned over.
If the size of is large, the upper air nozzle part l

[Example] As shown in FIGS. 1 and 2, the conveyor 2 is constructed by installing a large number of bars 2b at regular intervals between a pair of chain conveyors 28. The substrate support part 5 made of a wire material with a shape is attached. The ceramic substrate 1 is supported on this 7-shaped substrate support portion 5 and is conveyed by the conveyor 2.
In this case, the ceramic substrate 1 is tilted and supported so as to lean against one of the sloped portions 8 on both sides of the substrate support portion 5 having a letter 7 shape.

If the ceramic substrate 1 is supported by the inclined portion 8, even if the reversing air jetted from the reversing air jet nozzle 11 hits the ceramic substrate 1, the ceramic substrate 1 will not be reversed. Therefore, no matter which slope part 8 of the double-ended slope part 8 of the V-shaped substrate supporting part 5 supports the ceramic substrate 1 on the starting end side of the conveyor 2, the ceramic substrate 1 passes through the reversing air jet nozzle 11 part. Then, it is tilted and supported by the same inclined part 8 of the V-shaped substrate support part 5. By the way, there are a plurality of reversing air jet nozzles 11 arranged above and below (
