JPS59108639A - Feeder for platelike material with resilience - Google Patents

Abstract

PURPOSE:To feed platelike materials piece by piece without fail, by extruding a sheet of platelike materials at the lowest end just above a projecting part more inward than the projecting part by means of a push claw being thinner than each platelike material in thickness, while curving each of these materials downward and making it drop down with its dead load. CONSTITUTION:When a lot of elastic platelike materials such as reed frames and the like are laminated one after another and housed in the inner side of a guide plate 1 and a guide bar, a lower end of the longitudinal direction of each platelike material 15 is supported by a projecting part 14a of a platelike material supporting plate 14. Next, a motor is started, and in a state that a roller is rotated in a fixed direction via a sprocket and a chain, a push cylinder 16 is operated, moving a slide block 18 to the inner side, then a tip of its push claw 19 is extruded out of an opening part 14b of the supporting plate 14, and both ends of a sheet of these platelike materials 15 at the lowest end is extruded to the inner side with this push claw 19. Then, both ends of each platelike material 15 curved downward is detached from the projecting part 14a, dropping these materials 15 with its dead load, thus they are conveyed by the roller.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for stacking elastic plate-like objects, for example, thin metal plates such as lead frames, and feeding them one by one from the bottom to the next process. Frames with thin metal plates that have complex-shaped holes may have burrs or bends, or may have an oil film on the surface, resulting in the top and bottom being completely separated. When suctioning from above with an empty suction machine, two plates may be suctioned at once, or '! F
However, it is complicated to change the suction location depending on the position of the through hole in the lead frame, so it is preferable to use a mechanical method.

Therefore, feeding to the next process such as the Metsuki line was often done manually. [7] However, manual work is not only time-consuming, but also causes problems such as contamination and deformation of the lead frame, which impairs the quality of the product. ￥
Furthermore, when using the tangential method in which the stacked lead frames were taken out from one part, it was necessary to temporarily stop the machine when replenishing.

The present invention aims to eliminate such conventional drawbacks by using an elastic plate-like material such as a laminated lead frame.
Support both ends in the K-hand direction vertically* with an inner cutout and a protrusion protruding from the bottom, and press the bottom piece of the bottom piece directly above the protrusion with a pusher claw that is smaller than the plate-like object to the inside of the protrusion. By pushing it out, the plate-like object is curved downward, dropped by its own weight, and then fed to the next process by a conveying device. An embodiment of the present invention will be explained in detail with reference to the drawings below. Fig. 1 is a plan view showing an embodiment of the present invention supplying device, Fig. 2 is a side view thereof, and Fig. 3 is a rotating section. Front view, 4th
The figure also shows a side cross section of the main part. As shown in the figure, for example, two guide plates 1 for positioning both sides of a lead frame in the longitudinal direction are supported at their bases by guide plate holders 3 each attached to two sliding bearing boxes 2. The lock bolts 5 are tightened to the guide plates 4 and 4, and the spacing between the guide plates 10 on both sides can be adjusted by loosening the lock bolts 5 according to the lengths on both sides of the lead frame. It is now possible to do so. In order to determine the position of the stacked lead frames in the width direction, two each of four lead frame guide rods 6 and 6a are self-installed on the holding rail 7. As shown in FIG. 1, these two Hodoji rails 7 are fixed, one by one, to two holding rail holders 8 which intersect at right angles near both ends of the Hodoji rails 7 in the -F direction. This holding rail holder 8 has pedestals 8aK near both ends.

The support finger 14 is extended to one fork, and the support plate 14 has a protrusion 14a protruding from the inside 17, and this protrusion 1
An opening 141) which is thinner than the lead frame 15 is provided between the upper end of the lead frame 4a and the slide plate 13. Further, a cylinder 16 is fixedly attached to the push cylinder 16 of the inner plate 1r, and a slide block 18 that reciprocates is engaged with the cylinder 16. Further, in the lower part of this slide block 18, there is provided a pressing pawl 19, which is substantially the same as the first part 14b, with one end of the front end opening. The stroke of this push j7 pawl 19 can be extended by a stopper 20.

Next, below the lead frame support plate 14, a large number of rollers 21 are supported by a frame 22 in parallel at right angles to the longitudinal direction of the lead frame 15, and a sprocket 23 and a chain 2 are attached to one end of the rollers 21. - Connected to motor 5 via 1.

The operation of the supply device constructed as above will now be described. First, adjust the distance between the two interior panels 1 to the lengthwise dimension of the lead frame 15 (Fig. 4) with the lock bolt 5 using a2h, and then fix the lock bolt 5. Next, turn the handle 12a 1'1jlJ to connect the connecting rod 1.
2. Helical carrier 11, rack and pinion 10, rack 9
, the holding rail holder 8, and the holding rail 7 between the lead frame guide rods 6 and 6a. Then, when a large number of lead frames 15 are stacked and stored inside the guide plate 1 and the guide rod 6.6a, the lower ends of the lead frames 15 in the longitudinal direction are supported by the projections 14a of the lead frame support plate 14. (See No. 4131). Then, when the motor is started and the roller 21 is rotated 8 times in a certain direction via the chain wheel 24 and the sprocket 2-3, and the cylinder 16 is actuated, the slide block 18 moves to the slide 411II 17. Slide 12 to move inward. Therefore, when the lower part of the slide block 18 is fixed, the tip of the pushing pawl 19 can be pushed out from the opening part 14.

At this time, as shown in FIG. 4, both ends of the lead frame 15 are pushed inward and the lead frame 15 is curved downward [7, and when both ends come off the protrusion 14a. Since there is no supporting part, it falls downward under its own weight and is conveyed by the rollers 21. For this reason, it is preferable to make the tip of the protrusion 1.48 as thick as possible or to have a lower part. Thereafter, one lead frame 15 can be supplied one by one in the same manner.

As explained in detail in Section 7 below, it is possible to reliably feed the lead frames one by one to the present invention, and when the load is running low, it can be fed from the top at any time without stopping the device. Not only is it very efficient to replenish the product, it also prevents contamination of the product. It does not damage or deform the product, so it maintains the quality of the product! 1 can also be improved, resulting in extremely significant effects. Even if dimensions such as the length, width, or thickness of the cutting frame are changed, the spacing between the guide plates and guide rods can be changed.
Slide plate, lead frame support plate, push plate, etc. as required.
It is also highly versatile as it can be easily handled by replacing the claws and adjusting the stopper. At the same time, it is also possible to automate a series of culms unmanned by using a proximity switch, etc. as necessary. It can be applied to any elastic plate-like material.
