Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a supply device for parts with leads, and more particularly to a straight feeder that stores leads in a lead storage groove and transfers them in a suspended state.

2. Description of the Related Art A combination of a straight feeder 1 and a bowl feeder 2 as shown in FIG. 3 is used as an arrangement and supply device for leaded electronic components such as capacitors and resistors. When the electronic components 3 are first supplied to the bowl feeder 2, they are separated and sequentially sent to the straight feeder 1. Straight feeder 1 is opposite to the feeding end of bowl feeder 2.
At the same time, as shown in FIGS. 3 and 5, a lead storage groove 1a is formed in the transfer path, and a radial type lead 3b, for example, is stored in the lead storage groove 1a, and the component body 3a is suspended. Align and transfer.

Problems to be Solved by the Invention By the way, as described above, when arranging and transporting electronic components 3 with radial leads, for example, by the straight feeder 1, as shown in FIG. If it is larger than the width W [P
>W], parts that are adjacent to each other at the shoulder of lead 3b,
The electronic components 3 may overlap and become entangled, and may not be transferred smoothly. Furthermore, even in the case of P<W, if the lead 3c is bent in a direction perpendicular to the transfer direction X, as shown by the chain line in FIG. As shown by the chain line in Fig. 4, the transfer direction
Similarly, at the foot of the lead 3c, the lead 3c may become entangled with the adjacent part.

Means for Solving the Problems The present invention is an alignment and feeding device equipped with a straight feeder that aligns and transfers leaded components sent out from a feeder in a lead storage groove with the component bodies suspended. The lead storage groove is composed of a side wall block body having a notch in the center, the upper side wall interval of both block bodies is set to less than twice the lead diameter, and the lower side wall interval is larger than the upper electrode interval, and the lead It is characterized by being set to four times the diameter or less. In other words, a lead storage groove is formed in the transfer path of the leaded component, and the lead is stored in the lead storage groove to align and hang the component body.
A supply device for parts with leads, comprising a straight feeder for transporting the parts, and a feeder in which the sending ends of the electronic parts are arranged opposite to each other in the transport path,
Both side walls of the lead storage groove are formed into a U-shaped cross section, and the interval between the upper side walls of the U-shape is set to less than twice the lead diameter, and the interval between the lower side walls is larger than the interval between the upper side walls, It is characterized by being set to four times or less the lead diameter.

Function: In the straight feeder, which is composed of two side wall blocks, both side walls of the lead storage groove in the transfer path are formed in a U-shaped cross section, and the interval between the upper side walls of the U shape is set to less than twice the lead diameter. At the same time, the interval between the lower side walls is set to be larger than that and four times the lead diameter or less, and the shoulder and foot portions of the lead are supported and regulated by the upper and lower side walls of the lead storage groove having a U-shaped cross section.

Furthermore, even if the lead spacing P is smaller than the width W of the component body [P<W], even if the leads are bent in the direction perpendicular to the transfer direction Since the foot part of the lead is provided with an escape from the lead, it is difficult for the foot part of the lead to come into contact with the lower side wall, and transfer is not prevented. Therefore, the part body tilts along the transfer direction There is no such thing as getting involved.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In the figure, 3 is an electronic component with leads, for example, an electronic component with radial leads;
4a is a lead storage groove forming a transfer path for the straight feeder 4, and as shown in FIG. 2, the block bodies on both sides are formed into a U-shaped cross section. Configure. The distance d between the upper side walls _4a1 is 2 of the lead diameter l.
The distance between the lower side walls _4a2 is set to be larger than that and four times the lead diameter l or less, which is a feature of the present invention.

The lead 3 of the electronic component 3 is placed in the lead storage groove 4a.
When the leads 3b are stored and aligned and transferred, first, since the distance d between the upper side walls _4a1 of the lead storage groove 4a is less than twice the lead diameter l of the electronic component 3, the leads 3b overlap at the shoulders of adjacent components. There isn't. Therefore,
When the lead interval P is larger than the width W of the component body 3a [P>W], as shown in FIG.
The electronic parts 3 are smoothly transferred without overlapping and intertwining the parts whose shoulder parts b are adjacent to each other. or,
Even _{if the} lead 3b is bent in the direction perpendicular to the transfer direction , since the foot part of the lead 3b is unlikely to contact the lower side wall and transfer is not prevented, when P<W, the electronic component 3 will not tilt in the transfer direction The electronic components 3 are smoothly transferred without getting entangled with each other.

Note that setting the interval between the lower side walls 4a ₂ to be larger than the interval d between the upper side walls 4a ₁ and less than 4 times the lead diameter l means that if it exceeds 4 times, it will be difficult to transfer the parts. This is because the foot portion of the lead 3b of the electronic component 3 is not regulated and continues to swing in the direction perpendicular to the transfer direction X, making it impossible to transfer it smoothly.

Effects of the invention According to the invention, in an aligning and feeding apparatus for leaded electronic components that is a combination of a straight feeder having a lead storage groove and a bowl feeder, both side walls of the lead storage groove of the straight feeder have a U-shaped cross section. , and the interval between the upper side walls of the U-shape is set to less than twice the lead diameter, and the interval between the lower side walls is made larger than the interval between the upper side walls, and is set to less than 4 times the lead diameter. For example, when electronic components with radial leads are transferred in a straight line using a straight feeder, the shoulders of the leads are prevented from overlapping, and the foot area is regulated. Matching parts,
The leads are transferred smoothly without overlapping and tangling.

Furthermore, even if the lead is bent in a direction perpendicular to the transport direction, the gap between the lower side walls is larger than the gap between the upper side walls to provide escape from the lead, so the foot part of the lead is bent against the lower side wall. It is difficult to come into contact with the body, and there is no way to prevent it from being transferred. This prevents the component body from tilting along the transfer direction and becoming entangled with adjacent components at the foot of the lead.
