Abstract

PURPOSE:To reduce a sliding clearance and to secure a sure feeding for a sheet substrate feeder comprising a feeding table with concavities and feeding beams also with concavities capable of a vertical and longitudinal reciprocative motions by providing each of the bottom surfaces of the concavities in the beams with a inclined surface for correcting the position of the sheet substrate during feeding. CONSTITUTION:When a sheet substrate 11 is fed on the concavities 16a, 16b, 16c,... by means of the repeat of a cycle consisting of lift, advance, descent, and retreat of feeding beams 13, the substrate 11 slides on inclined surfaces 14 in the direction shown by an arrow 19 due to the inertial of the motion of the feeding beams 13 in the direction shown by an arrow 18 until the substrate 11 abuts against steps at the ends of the inclined surfaces 14, where the substrate 11 is stably located. Accordingly, the substrate 11 is transferred to the subsequent concavity 16b, being stably disposed in a correct position. Thus, a smooth feeding can be secured.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention comprises a conveyor table having an arbitrary number of grooves, and a conveyor rod adjacent to both sides of the conveyor table and having the same number of grooves as the conveyor table. This relates to a sheet-like substrate conveying device that transfers a sheet-like substrate from a table groove to a conveyor rod groove, moves the sheet-like substrate in an upward and advancing direction, lowers the sheet-like substrate, and transfers it to the next conveyor table groove. .

2. Description of the Related Art Conventionally, this type of sheet-like substrate conveyance has been configured as shown in FIG. In Fig. 7, 2 is a conveyance table, 3 is a conveyance rod, and 1 is a sheet-like substrate.
Concave grooves 4.5.6 provided in the transport platform 2 by drawing
The sheet-like substrate 1 was conveyed in this order.

Problems to be Solved by the Invention In such a conventional configuration, when the sheet-like substrate 1 is transported through the transport table grooves 4, 6, 6, etc. shown in FIG. The width b1 of the groove 4 of the conveyor table 2 must be bl>a with respect to the width d of the sheet substrate 1, and the width b1 of the groove 4 of the conveyor table 2 must be greater than a. C4〉bl for a smooth transfer to the groove 8, and b? C1 and the result is d<bl<C1×b
2〈C2〈b3〈C3 . The sheet-like substrate 1 moves a large amount on the conveyor rod 3 and the conveyor table 2 due to slippage, etc., which causes conveyance troubles.

The object of the present invention is to suppress the slip clearance and reduce transportation troubles.

Means for Solving the Problem In order to solve this problem, the present invention provides an inclined portion on the bottom surface of the concave groove of the conveying rod to correct the position of the sheet-like substrate during conveyance.

With this configuration, the sheet-like substrate is transferred to the groove of the conveyance rod, and when the conveyance rod moves, it slides stably on the slope of the groove of the conveyance rod, and the sheet substrate is placed in the groove of the next conveyance table. Transfer to the groove can be performed smoothly and stable conveyance can be achieved.

Embodiment FIG. 1 shows an embodiment of the present invention, which is a conveying device for a square plate-shaped chip resistance board. In FIG. 1, 11 is a square plate-shaped chip resistance board, 12 is a conveyance table, 13 is a conveyance rod, and 14 is a conveyance rod 1.
Reference numeral 3 indicates a groove inclined portion, 15 indicates a groove of the conveying rod 13, and 16 indicates a groove of the conveyor table 12.

An arrow 17 indicates the movement of the transport rod 13.

With this configuration, the concave groove 16a of the conveyor table 12 shown in FIG.
, 16b, 16c...
When the sheet-like substrate 11 is transported, as shown in FIG.
When the substrate 11 is placed on the groove 15a of the conveyor rod 13 and the conveyor rod 13 moves as shown by the arrow 18, the sheet-like substrate 11 slides on the inclined part 14 of the bottom of the groove 16 of the conveyor rod 13 as shown by the arrow 19. The transport platform 12 is moved to a stable state as shown in FIG.
The sheet-like substrate 11 can be reliably transferred to the groove 16, and stable conveyance can be achieved overall. in this case,
In FIG. 2, the width of the sheet-like substrate 11 and the transport rod 13 are
The width b1 of the groove 16 of the conveyor table 12 is bl>a-, and when transferring from the groove 16 of the conveyor table 12 to the groove 15 of the conveyor rod 13, the width d1 of the groove 15 of the conveyor rod 13 is dl>b, However, since the sheet substrate 11 is transported in the state shown in FIG. The relationship between d1 and the width b2 of the groove 16b of the transport platform 12 does not have to be bl>dl.

In other words, if d, > b, > a, transfer is possible and the result is d1=d2=d3=...>b1
=b2=b3...>a allows stable conveyance. As a result, the clearance between the width a of the sheet-like substrate 11 and dN-bN in the concave grooves of the transport rod 13 and the transport table 12 can always be small, and this effect also allows for more stable transport. Further, as shown in FIG. 6, if the inclined portion 14 & having a larger inclination angle is provided, the sheet-like substrate 11 will be smoother and smoother in the direction of the arrow 19.
It becomes easier to achieve a stable conveyance state like the sheet-like substrate 11 shown in the figure.

Effects of the Invention As described above, according to the present invention, there is provided a conveyor table having an arbitrary number of grooves, and a conveyor table having the same number of grooves as the conveyor table adjacent to both sides of the conveyor table. A conveying device consisting of a conveying rod that moves in the direction of transferring the substrate and moving it up and forward, then lowers the sheet-like substrate, transfers it to the next conveying table groove, and retreats.
The effect of more stable conveyance can be obtained.
