Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates mainly to the transportation of lightweight and thin components in electronic component mounting equipment, printed circuit board manufacturing equipment, semiconductor manufacturing equipment, and the like.

Structure of the conventional example and its problems The conventional conveyance mechanism has a concrete structure as shown in Fig. 1.
A feed rod 2 to which a feed claw 1 is attached is reciprocated in the conveying direction, and the feed rod is swung to move the feed claw up and down to feed the object 3.

However, the above configuration has the following drawbacks.

0) If multiple feed pawls are installed at a fixed pitch, the distance between the feed pawls will be p"'m from 9 feed pitches, so the feed rod cannot be supported between the feed pawls, and the rod will become long. If the rod is too long, the rod will bend and the conveyance condition will become unstable.

(2) Since the feed rod makes reciprocating and oscillating movements, it is extremely difficult to support the feed rod at the part where the feed claw is attached, and in addition, the weight of the moving parts including the feed rod and feed claw is heavy. It becomes large and high-speed conveyance becomes unstable.

Purpose of the Invention In view of the above-mentioned drawbacks, the present invention aims to strengthen the bearing guide of the feed rod, reduce the weight of the parts that move in the direction of gravity, such as swinging up and down, and thereby stabilize and speed up the feed operation. That is.

Composition of the invention The structure of the present invention is as follows.

The object to be transported is received and guided by fixed guide rails at both left and right ends in the transport direction. The feed rod is disposed below the conveyance surface and is supported by a bearing so that it can reciprocate in the conveyance direction. A single rotation axis is provided on this feed rod 9, and a feed pawl that swings around this shaft is attached. When this pawl is swung in one direction, one end of the pawl protrudes slightly from the conveying surface at the swing limit, and in the opposite direction. Set it so that when it swings, it will be below the conveyance surface.

The other end of the feed pawl is brought into contact with the feed pawl upper and lower rails provided in parallel with the feed rod. The feed claw upper and lower rails must have an appropriate length to allow the feed claw to be in constant contact with the feed rod while the feed rod reciprocates. The feed pawl upper and lower rails are guided by bearings so as to be able to move up and down, and the feed pawls in contact with the rails are swung upward and downward.

The above is the configuration of the present invention. With this, the feed rod performs only reciprocating motion, and is driven by a separate path from the vertical movement of the feed claw, so the 52 movements of the feed rod reciprocation and the up and down movement of the feed claw are performed completely separately. It has the unique effect of providing strong bearing guidance.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 shows a conveying device in one embodiment of the present invention.

In FIG. 2, 4 is an object to be transported, 5 is a guide rail for guiding the object, 6 is a feed rod, T is a feed claw attached to the feed top, and 8 is a feed claw upper and lower rail.

The operation of the transport device configured as described above will be described below. The objects to be transported are supported and guided by guide rails. To convey this, the feed claw upper and lower rails are lowered, the feed claw is swung forward, and the feed rod is advanced with the tip of the claw protruding from the conveyance surface. When the conveyed object has been completely fed, the upper and lower rails of the feed claw are raised, the feed claw is swung backwards, and the feed rod is moved back with the tip of the feed claw being below the conveyance surface.

As described above, in this embodiment, the driving force is transmitted through independent operating paths: the front and rear of the feed rod for the front and back of conveyance, and the vertical movement of the feed claw upper and lower rails for the upper and lower sides of the feed claw. I can do it.

In this embodiment, the feed pawl was raised in response to the lowering of the feed pawl upper and lower rails, but this was achieved by bending the shape of the feed pawl in the opposite direction to raise the feed pawl upper and lower rails. It goes without saying that you can raise your nails.

Effects of the Invention As described above, the present invention provides reciprocating motion through a single feeding rod,
Unlike the conventional method in which the feeder claw moves up and down, it can be guided by bearings independently, which provides strong support for movement, and also minimizes the number of feeder claws that move in the direction of gravity, resulting in stable and high-speed transfer operation. It can be said that it is extremely effective for

In the conventional example, the feeder 9 itself rotates and moves back and forth, so if it is placed between the partial feeder claws that support it, it cannot move back and forth with a stroke longer than the spacing between the claws, but with the present invention, these two movements are completely possible. Because they are separate, there is no restriction on strokes.
