Abstract

PURPOSE:To keep a rectangular plate piece from adhesion of dust furing transportation by providing a plurality of gas jet nozzles for ejecting clean gas obliquely relative to the transport direction so as to float and transport the rectangular plate piece. CONSTITUTION:Nitrogen gas supplied from a hose joint 1G is passed through gas paths 1D1, 1A2, 1A3, 1B2, 1C2 to be ejected from a gas jet nozzle 1A of the base of a transport path and gas nozzles 1B, 1C of the sides of the transport path, so that a transported article 3 on a chute 1A is floated from the base of the transport path to be kept from contact with guide plates 1B, 1C and transported. The ejected gas from the sides of the transport path can eliminate damages of article 3 due to contact of the article 3 with the guide plates 1B, 1C and prevent the article from being caught in the middle of the transport path to increase the speed of transporting the article 3. Thus, the article can be transported more reliably.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveying device for rectangular plate pieces. Conventionally, such rectangular plate pieces have been transported using methods such as transporting with a flat plate, transporting with a vacuum chuck, and transporting with a puller. The adhesion force was unsuitable in some cases. This invention relates to a conveying device tVc for rectangular plate pieces in such a case, and it can be used to automate machines that have been difficult to automate due to problems such as damage to conveyed objects, adhesion of dust, and debris. The purpose is to diagram, save labor, and rationalize. The conveying device for rectangular plate pieces according to the present invention includes: 9) a chute extending downward on four sides, and a clean gas such as extinguishing air;
Plan 9: Use gas, etc.

Here, this invention will be explained based on the drawings as an example using nine elemental gases. As shown in FIG. 1, the device used for conveyance consists of a chute 1 and a sheet 2.
In addition, nitrogen gas is used as a transport gas. The conveyance process of the conveyed object will be schematically explained according to FIG. The conveyed object 3 in the shape of a rectangular plate is fed from the direction of the arrow of the chute 1, and is floated by nitrogen gas ejected from the bottom of the conveyance path to generate a thrust in the direction of the arrow, and is also flown in a tape to avoid damage to the conveyed object 3. <.

Nitrogen gas is ejected in the transport direction from the side of the transport path as well, and the material is transported. The conveyed object 3 that has reached chute 2VC is transferred to chute 1.
Change the direction perpendicular to the transport direction.

Similarly, it is transported to the exit of chute 2. The conveying method in the chute 1 will be explained in detail with reference to FIGS. 2, 3, and 4.

shoe) 1Vi, gas ejection hole 1A facing the conveyance direction,
A chute 1A1 is provided with a gas passage IA, and a gas passage IA for ejecting gas from the side surface of the conveyance path. Gas ejection holes 1B, , I'c, and their gas passages IBt are formed and oriented in the conveyance direction.
, 10x, the guide plates 1B, 1C, the lower surface of the chute 1A, and the gas passage 1At of the ate 1A,
A shade bottom plate 1D equipped with a gas passage 11 communicating with the IAaiC and a hose fitting 1G for the gas supply port, several screws 1E for assembling and fixing these parts, and the amount of conveyance paths for chute 1 and chute 2. Screw 11F# to match and secure! It consists of i pieces. The conveyed object 3 on the chute 1A is supplied with **gas supplied from the hose joint 1G, or each gas passage ID+, 1 kt.
, I As , I B21 Pass through Ct, gas outlet hole I on the bottom surface of the conveyance path I AI Gas outlet hole I on the bottom surface of the conveyance path
By ejecting from B1.10+, it rises above the bottom surface of the conveyance path and is conveyed while preventing contact with the guide plates 1B and 1cJ. Due to the gas ejected from the surface of the conveyance path 111, the conveyed article 3 is brought into contact with the conveyed article 3 and the guide plates IB and 10.
This eliminates damage to the paper, prevents scratches during transportation, and improves transportation.
3, it is possible to increase the conveyance speed and perform more reliable conveyance. As shown in FIGS. 2, 5, 6, 7, and 8, the chute 2 also has one shade 2^, guide plates 2B, 20, 2D, chute bottom plate 2! , several screws 2F for assembling those parts, several screws 2G for fixing the chute 2, and a hose joint 2H.
It consists of 12 engineering and 2 J. In the chute 2, in order to change the conveyance direction of the conveyed object 3 which has been conveyed from the shade 1 and convey it, a gas ejection hole 2A opened in the same direction as the shoe) 2A and the shoe) IA, It is provided with a gas ejection hole 2A that is opened in the direction of conveyance.

In addition, the guide plates 2 (!, 2D) are also similar to the guide plates IB, 10, and the gas ejection holes 2C, 2 are aligned with the direction of conveyance.
D. The conveyed object 3 is conveyed from the chute 1, and the nitrogen gas supplied to the hose joint 2H flows through the gas passage 21! s , 2 At, gas ejection hole 2
When it ejects from A+, it goes further in the same direction and guide plate 01
It hits C and stops. Here, the arrival of the conveyed object 3 on the chute 2 is detected by a sensor, a timer, etc., and the hose joint IG of the chute 1 is connected.

Stop the supply of 9-element gas to the hose joint 2H of chute 2, and at the same time, close the hose joint 2N of chute 2.

When 2JK nitrogen gas is supplied, each gas passage 2E'
2A@,' 2Bs, 2A4, 2A? , 2C! t, 2
D Through the snow, each gas outlet 2A5, 2As, 20t

Same as sheet 1 conveyance, change the conveyance direction and convey @
llS is transported to the exit of chute 2. As is clear from the above-mentioned silence, the rectangular plate conveying device according to the present invention can be used without causing damage to the conveyed object.
Furthermore, by using clean gas, the attachment of dust and the like can be avoided.

In addition, the structure is simple, and there are no mechanical driving parts, making maintenance easy. . Furthermore, it is possible to perform stable conveyance, improve the operating rate of one machine, and enable highly reliable automation.
