Description

[Detailed Description of the Invention] The present invention relates to an apparatus for automatically counting lead wire terminals and the like used in electronic components such as capacitors and resistors.

Conventionally, as a means of counting the number of processed lead wire terminals used for capacitors, resistors, etc., the lead wire terminals flowing during work are captured by a photoelectric switch, and this detection signal is connected to a counter or the photoelectric switch Instead, a proximity switch was used or a touch switch was touched to the lead wire to operate the amplifier, and the amplifier was then connected to a counter.

However, lead wire terminals, etc. are usually processed automatically and at high speed, so when using the aforementioned photoelectric switch or proximity switch, the wire diameter is 1 wig or less due to the detection ability of the switch. It is not suitable for detecting lead wire terminals, etc., and can only be used for wires with a diameter exceeding these.

Since the sensor portion of the photoelectric switch or proximity switch enclosed in the housing is relatively large, there is a problem in that it takes up a large amount of space when installed in an automatic machine.

Furthermore, when the above-mentioned touch switch is used, the head of the touch switch is large, and like the photoelectric switch and proximity switch, it takes up a large space when installed, and is also expensive, making the entire device expensive and large. It had drawbacks.

The present invention has been devised in view of the above-mentioned points, and it is an object of the present invention to provide a device that is capable of reliably detecting and counting even small-diameter lead wire terminals and the like in automatic machines operating at high speed.

The implementation will be explained below.

As shown in Fig. 1, a drum 1 of the main body of the device is attached to a main shaft 2, and a magnet 3 is placed on a part or the entire surface of its circumference.
has been established.

Lead wire terminals 4 and the like attracted to the magnet 3 on the circumferential surface at regular intervals are sequentially fed by the rotation of the drum 1.

Further, a claw 5 provided at a predetermined distance from the drum 1 is used to peel off lead wire terminals 4 and the like adsorbed on the circumferential surface of the drum 1 from the drum 1 and drop them into a chute 6. 1 and moves repeatedly in the direction of the arrow by the circular motion of the rotating shaft 7.

A device having such a mechanical configuration is connected to an electrical circuit shown in FIG.

In FIG. 2, 8 is a reset microswitch, 9 is a counting counter, and 10 is an SCR. A terminal 11 is connected to the drum 1, and a terminal 12 is connected to the claw 5.

The counting device for lead wire terminals and the like having the above configuration operates as follows.

That is, the lead wire terminals 4 that have been attracted to the magnet 3 of the drum 1 and sent are removed one by one by the claws 5 that repeatedly operate due to the circular motion of the rotation axis γ and are stored in the chute 6, but as shown in FIG. Terminal 11 shown is connected to drum 1, terminal 1
Since the lead wire terminal 2 is connected to the claw 5, when the lead wire terminal 4 is removed from the drum 1 with the claw 5, the lead wire terminal 4 is electrically connected through the lead wire terminal 4.

When the 5CR10 is turned on and conductive due to the connection between the drum 1 and the pawl 5, the counting counter 9 is also energized, so that counting is performed.

Terminals 11 and 12, which were connected via lead wire terminal 4, are electrically turned off by brushing off lead wire terminal 4 with claw 5, but counting counter 9 operates due to the self-holding property of 5CRI O. After that, the reset microswitch 8 is turned OFF based on mechanical timing to turn off the 5CR10.

By repeating this operation, the number of lead wire terminals 4 sent sequentially is automatically counted.

Of course, timing the operation of the drum 1 and the pawl 5 is beyond the scope of discussion, and the electrical connections are made by connecting the device body that is electrically connected to the drum 1 and the pawl 5, etc., which are insulated from the device body. You may.

In the above, if a V groove is formed on the circumferential surface of the drum 1 and the lead wire terminals 4 etc. are locked in the V groove, it becomes easier to attract the lead wire terminals 4 etc. at regular intervals.

As described above, the counting device for lead wire terminals, etc. of the present invention automatically counts by connecting two terminals through the lead wire terminal, etc., so it is possible to count any thin lead wire terminal, etc. Since the claws, which are both possible and essential for the machine's configuration, are used as counting terminals, there is no need to install photoelectric switches, proximity switches, touch switches, etc. separately from the machine, which is required in the past, so the installation space is significantly reduced. This is very advantageous in terms of counter arrangement.

Micro switch for resetting 8. Counter 9
．． Since the electrical circuit is constructed of 5CR10 and the like, and there are no mechanically added parts, the device also has the effect of being extremely inexpensive.

In the above embodiment, a device is described in which a magnet 3 is arranged on the circumferential surface of the drum 1 to attract lead wire terminals 4 and the like and sequentially feed them out, but for example, as shown in FIG. For example, a structure in which terminals 11 and 12 shown in FIG. 2 are connected to the parts feeder 21 and the magnet 24, respectively, or a fourth
As shown in the figure, lead wire terminals, etc. 3 are placed between carriers (chains have the same effect) 31 and sent.
2 is flipped up by the transfer claw 33 and stored in the container 34, and the same effect can be obtained in an embodiment in which the terminals 11j12 shown in FIG. 2 are connected to the carrier 31 and the transfer claw 33, respectively. be able to.

Furthermore, it is not necessary to mention that the same effect can be obtained not only with a lead wire terminal but also with a lead wire alone or with a lead wire processed or welded.
