Abstract

PURPOSE:To combine a base plate carrying out table with a discharging conveyor so as to make the total length of a device half of a customary one by supportingly sending a plate to be processed of the uppermost step lifted with a hoisting mechanism in the horizontal direction, and providing a carrying conveyor having variable length. CONSTITUTION:When a base plate 1a is raised up to a decided position with an elevatable table 2, an suction pad 3 descends, and then ascends, sucking the end part of a base plate 1a of the uppermost position. Nextly, when the substrate 1a of the uppermost position is elevated and a conveyor shaft 5a advances to the gap formed between the upper base plate 1a and the lower one 1b, the under face of the plate 1a of the uppermost step is supported with a base plate supporting roller 4. When the conveyor shaft 5a advances further, conveyor shafts 5a, 5c, 10a are arranged in a line on a balance weight L and carrying conveyors 6a, 6b are tensilely provided in series. Accompanied with carriage of the base 1a, the conveyor shaft 5a retreats to the right, and the length of a carrying conveyor 7 in the horizontal direction is reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a board loading machine, and particularly to a board loading machine for loading printed wiring boards (hereinafter referred to as substrates) into a conveyor device.

[Conventional technology]

Conventionally, in this type of substrate loading machine, as shown in FIG. 3, when a lifting table 2 on which processing target plates (substrates) 1 stacked vertically is lifted to the upper limit position.

The uppermost substrate 1 on the lifting table 2 is sucked and pulled up by the suction pad 3, and the lifted uppermost substrate I is
When the substrate ejection table 11 enters the upper and lower Q sides and the substrate ejection table 8 reaches the rear end of the J& board 1, the suction pad 3 is released and the substrate 1 is transferred onto the substrate ejection table 8. The substrate discharge table 11 supporting the substrate 1 retreats toward the lower side of the pass line L of the discharge conveyor 9 (fourth
(see figure).

At this time, the substrate 1 is transferred onto the discharge conveyor 12 and discharged by the discharge conveyor 12 6 [Problem to be Solved by the Invention] In this conventional substrate loading machine, the elevating table 2 has the maximum size of the processing plate. Furthermore, since the processing plates are discharged horizontally by the discharge conveyor 9, the length of the discharge conveyor 9 must be approximately twice the maximum size of the processing plates. In other words, the total length of the conventional substrate loading machine is three times the minimum and maximum processing board size.

As mentioned above, a conventional board loading machine requires a length approximately three times the maximum size of the processing board, but as the board size increases year by year, conventional board loading machines become large devices and take up space on the installation floor. This is beginning to have an impact on security.

An object of the present invention is to provide a substrate loading machine that solves the above problems.

[Differences between the invention and the prior art]

The substrate loading machine according to the present invention differs from the conventional substrate loading machine described above in that the total length of the device can be reduced to 1/2 of that of the conventional device by combining the substrate discharge table and the discharge conveyor.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention provides a substrate loading machine for feeding plates to be processed into a conveyor device, which includes an elevating table that lifts and lowers stacked plates to be processed vertically, and an elevating table that rises to an upper limit position. A lifting mechanism that sucks and pulls up the uppermost processed plate to separate the upper and lower processed plates from each other, and a lifting mechanism that supports the uppermost processed plate lifted by the lifting mechanism and feeds it in the horizontal direction. , and a conveyor whose length changes in the feeding direction.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

Fig. 1 is a configuration diagram showing an embodiment of the present invention, Fig. 2(a)
-(d) are operation explanatory diagrams showing one embodiment of the present invention.

First, the present invention will be explained in detail using FIG.

An elevating table 2 on which the substrates 1 stacked vertically is mounted is tilted approximately 15 degrees downward from a horizontal plane toward the advancing direction of the substrates 1, and is installed so as to be movable up and down.

The lifting table 2 is moved up and down by an air cylinder or the like to the upper limit position of the lifting table 2, and the uppermost substrate 1a on the lifting table 2 is sucked and pulled up.
Suction pads (lifting mechanisms) are arranged in parallel to separate them.

Further, a conveyor 7 is provided which supports the uppermost substrate 1a pulled up by the suction pad 3 and feeds it in the horizontal direction, and whose length changes in the feeding direction. The conveyor 7 includes a roller 4 as a substrate receiver, a conveyor shaft 5a that enters the lower surface side of the lifted uppermost substrate 1a, and a conveyor shaft 5b that ascends and descends.
Conveyor shaft loa, 10b, pivotally supported in fixed position;

a, and a conveyor 6b which is suspended from conveyor shafts 5c, lOa, and Iob.

Next, the present invention will be explained in detail using FIGS. 2(a) to 2(d).

When the board 1 is raised to a fixed position by the lifting table 2,
The suction pad 3 descends, attracts the edge of the topmost substrate 1a, and rises (FIG. 2(a)).Then, as shown in FIG. 2(b), the topmost substrate 1a rises. the upper and lower substrates 1a,
The conveyor shaft 5a is strung toward the gap formed between the conveyor shafts 5b and 5c.
rises. The lower surface of the lifted uppermost substrate 1a is supported by rollers 4, and when the conveyor shaft 5a reaches the forward end, it is compacted and the two conveyors 6a and 6b, which are suspended from each conveyor, are Conveyor conveyors 7 arranged in series along the pass line L are stretched horizontally. The adsorption of the suction pad 3 is released and the substrate 1a is transferred onto the conveyor 6a. On the other hand, suction pad 3
rises from that position. In this state, the substrate 1a is conveyed horizontally by the conveyor 7.

As shown in FIGS. 2(c) and 2(d), the conveyor shaft 5a retreats to the right in the figure as the substrate 1a is transported.
While the conveyor shaft 5b is descending, the conveyor 6a rotates in the direction of arrow e, and the conveyor 6b rotates in the direction of arrow f, whereby the substrate 1a is sent out and the conveyor 7 is horizontally is reduced.

〔Effect of the invention〕

As described above, the present invention has the advantage that by integrating the substrate ejection table and the ejection conveyor, the overall length of the apparatus can be reduced to 1/2 of that of the conventional apparatus, and the installation floor can be easily secured.
