DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a transport device that can accurately transport coaxial lead type circuit elements such as capacitors and resistors in the horizontal direction.

Prior Art FIGS. 1 and 2 show a circuit element 4 consisting of a cylindrical or cylindrical element body 1 and a pair of lead wires 2 and 3 led coaxially from the center of both sides of the element body 1, which is transported in a horizontal direction. This figure shows a conventional device for doing this. This conventional conveying device consists of first and second conveying bodies 9 and 10 constructed by attaching a pair of attachments 7 and 8 to a pair of endless chains 5 and 6. As is clear from FIG. 2, the pair of attachments 7 and 8 have grooves 11 and 12 at a constant pitch that are open at the top, and support the pair of lead wires 2 and 3 and move together with the chains 5 and 6. As a result, the circuit element 4 is horizontally transferred in the right direction as indicated by the arrow in FIG.

By the way, due to vibrations during transportation, the lead wires 2 and 3 jump out of the grooves 11 and 12 in their normal positions, as shown in the circuit element 4a in FIG.
an abnormal condition such that the circuit element 4 in FIG.
As shown in b, only one lead wire 2 is connected to the adjacent groove 1.
1 may occur. If such an abnormal state occurs, it becomes difficult to properly process not only the abnormal circuit elements 4a and 4b but also the normal circuit elements 4 before and after these in the next process. It is conceivable to solve this kind of problem by determining and removing the abnormal circuit elements 4a and 4b using the human eye or an optical method. However, this results in an increase in man-hours or equipment costs. Also,
It is difficult to distinguish between normal circuit elements 4 and abnormal circuit elements 4a and 4b.

OBJECTS OF THE INVENTION Accordingly, an object of the present invention is to provide a coaxial lead type circuit element transporting device that can remove abnormal circuit elements and normally transport the circuit elements with a simple configuration.

Structure of the Invention The present invention for achieving the above object will be described with reference to the reference numerals in the drawings showing the embodiments for easy understanding.
This is a device for sequentially horizontally conveying a plurality of coaxial lead type circuit elements 4 consisting of a pair of bendable lead wires 2 and 3 coaxially extending from a a first transporting body 9 that moves while supporting one of the pair of lead wires 2 and 3 of the plurality of circuit elements 4 in the groove 11;
A plurality of grooves 12 arranged at the same pitch as the grooves 11 of the first transfer body 9 support the other of the pair of lead wires 2 and 3 of the plurality of circuit elements 4, and The first
A second transport body 10 that moves in synchronization with the transport body 9 of
The circuit element 4 has a plurality of recesses 16 on its outer peripheral surface arranged at the same pitch as the grooves 11 and 12 of the first and second transfer bodies 9 and 10, and the recess 16 is one circuit element 4. It is formed in such a way that it is impossible to accommodate the element body parts 1 of a plurality of circuit elements 4, and the first and second transport bodies 9, 10 The element main body 1 of the circuit element 4, which is normally transferred horizontally by the recess 16, is arranged so that it can automatically enter the recess 16 and then automatically exit from the recess 16. and a second transport body 9,
A roller 15 that is rotationally driven in the transfer direction of the circuit element 4 in synchronization with 10 does not engage with the circuit element 4 in a normal state that is normally transferred in the horizontal direction, but the circuit element 4 in the normal state Circuit elements 4a, 4 in an abnormal state located below the height position of
Abnormal circuit element removal engaging members 18 and 19 have tip ends 20 disposed at engaging positions and have inclined surfaces 21 that gradually push down the circuit elements 4a and 4b in the abnormal state, and This relates to a coaxial lead type circuit element conveying device consisting of the following.

Effects of the Invention In the above invention, the roller 15 has a recess 16 for accommodating one element main body 1 of the circuit element 4.
Since the roller 15 and the first and second transport bodies 9, 10 are driven synchronously to transport the circuit element 4 in the horizontal direction, the circuit element 4 is not supported abnormally by the grooves 11, 12 of the transport bodies 9, 10. If the circuit elements 4a and 4b are present, they will not engage properly with the roller 15, and the abnormal circuit elements 4a and 4b will be pressed lower than the normal circuit element 4. On the other hand, this device has an inclined surface 21 and engaging members 18 and 1 disposed such that the tip 20 is located above the abnormal circuit elements 4a and 4b.
9, the abnormal circuit elements 4a, 4b are engaged with the engaging members 18, 19 and pushed down, the lead wires 2, 3 are bent, and the abnormal circuit elements 4a, 4
b is completely removed from the normal transfer position or is in a state where it can be easily removed. Therefore, removal of circuit elements 4a and 4b in an abnormal state can be easily achieved with a simple configuration.

Moreover, since the abnormally placed circuit elements are found using the roller 15 which has a plurality of recesses 16 and is driven to rotate synchronously, the abnormally placed circuit elements can be removed while maintaining a high transfer speed.

Embodiment Next, a conveying device according to an embodiment of the present invention shown in FIGS. 3 to 7 will be described. However, since the parts indicated by reference numerals 1 to 12 in FIGS. 3 to 7 are substantially the same as those shown by the same reference numerals in FIGS. 1 and 2, the explanation thereof will be omitted.

As is clear from FIGS. 3 and 4, a pair of endless chains 5, 6 and an attachment 7,
The first and second transport bodies 9, 10 consisting of 8 are arranged in parallel as in FIGS. 1 and 2,
The circuit element 4 is supported and moved to the right as indicated by the arrow 14 in FIG. 3 so that the height position of the center of the circuit element 4 in a normal state coincides with the chain line 13 in FIG. Although not shown, a drive source for driving the first and second transport bodies 9 and 10 synchronously is provided.

Reference numeral 15 denotes a newly provided roller, and recesses 16 are provided on its outer peripheral surface at a pitch equal to the pitch of the grooves 11 and 12 of the attachments 7 and 8. This recess 16 is formed to removably accommodate the main body 1 of the circuit element 4, and is formed so as to accommodate at least a portion of the main body 1, but is unable to accommodate a plurality of main body 1. ing. Although the recess 16 is shown only on a part of the outer peripheral surface of the roller 15 in FIG. 3, it is of course provided on the entire outer peripheral surface. The roller 15 is placed in the center of the pair of attachments 7 and 8, and is placed in such a way that the chain line 13 indicating the center height position of the circuit element 4 in a normal state passes through the lowermost recess 16. In synchronization with the second transport bodies 9, 10, arrow 1 in FIG.
The circuit element 4 is rotated in the transport direction indicated by 7 by a motor (not shown).

As is clear from FIG. 4, a pair of circuit element removal engaging members 18 and 19 are provided below the roller 15. Tips 2 of these engaging members 18 and 19
0 is a pair of lead wires 2, 3 of the circuit element 4, which are arranged slightly below the height position of the lowest point of the roller 15 and housed in the recess 16 at the lowest point of the roller 15, as shown in FIG. It is located slightly below. Further, the engaging members 18 and 19 have an inclined surface 21. This inclined surface 21 is formed so as to push down the abnormal circuit elements 4a and 4b shown in FIGS. 5 and 7 as they are transferred.

22 is a circuit element scraping claw, and roller 23
Multiple pieces are provided around the outer periphery of the . Roller 23 rotates in the opposite direction to upper roller 15, as shown by arrow 24 in FIG. As a result, if there are circuit elements 4a, 4b in an abnormal state at the position where the claw 22 passes, they are forcibly removed.

Next, the operation of this transport device will be described. Third
When the circuit element 4 is normally transferred as shown in FIG.
8 and the claw 22 have virtually no effect on the circuit element 4. That is, the main body 1 of the circuit element 4 is sequentially engaged with the recess 16 of the roller 15, but the pitch of the recess 16 and the grooves 1 of the attachments 7, 8 are different from each other.
Since the pitches 1 and 12 are identical and driven synchronously, the rollers 15 do not interfere with the transport of the circuit elements 4. Furthermore, since the tip 20 of the engaging member 18 is located below the lead wires 2 and 3 of the normal circuit element 4, it does not engage with the lead wires 2 and 3.

On the other hand, if the lead wires of the two circuit elements 4 and 4a enter the same grooves 11 and 12 shown in FIG. 1, as is clear from FIG. Since it is impossible to accommodate the body part 2 of two elements 4, 4a, the upper element 4 is accommodated in the recess 16, and the lower element 4a
It will be in a state where it sticks out. That is, since the roller 15 rotates with its central axis 15a kept at a constant position, the upper limit position of the main body 1 of the elements 4, 4a is determined by the bottom of the recess 16 of the roller 15, while the The lower limit position of the lead wires 2, 3 is the groove 11 of the pair of attachments 7, 8, as shown in FIG.
12. For this reason, the upper element 4
The lower element 4a is pushed down by the roller 15 via the roller 15, and the pair of lead wires 2 and 3 are bent. As a result, the tips 2 of the engaging members 18 and 19
0 is located above the lead wires 2 and 3 of the circuit element 4a in the abnormal state. Abnormal circuit element 4a
Since the lead wires 2 and 3 are also being transferred in the direction shown by the arrow 14, the lead wires 2 and 3 enter under the sloped surfaces 21 of the sloped engagement members 18 and 19, and are guided by the sloped surfaces 21 and moved in the direction shown by the arrow 25. do. As a result, the lead wires 2 and 3 are bent further, and the abnormal circuit element 4a separates from the attachments 7 and 8 and falls. Note that since the claw 22 is rotating counterclockwise in FIG. 5, if the abnormal circuit element 4a has not yet fallen when the claw 22 passes, the claw 2
2, it is forcibly removed.

Abnormal circuit elements, such as those shown at 4b in FIG. 1, are removed as shown in FIG. That is, since the abnormal circuit elements 4b are not arranged at a constant pitch,
It is impossible to enter the recess 16 of the roller 15. Therefore, the protruding outer circumferential surface of the roller 15 pushes down the lead wires 2 and 3, bending them similarly to the abnormal circuit element 4a in FIG. When the abnormal circuit element 4b is moved to the right as shown by the arrow 14, the lead wires 2,
3 engages with the inclined surface 21, the lead wires 2 and 3 are further bent, and the circuit element 4b is separated from the attachments 7 and 8.

As is clear from the above, according to this embodiment, the abnormal circuit elements 4a, 4b can be easily removed by the action of the roller 15 and the engaging members 18, 19.
Furthermore, since the claw 22 is provided, the inclined engagement members 18, 1
Even if there is something that is not removed by 9, it can be definitely removed.

Modifications Although the embodiments of the present invention have been described above, the present invention is not limited thereto, and, for example, the following modifications are possible.

(A) The upper surfaces of the engaging members 18 and 19 are elements 4a and 4b.
Since it has nothing to do with the guide of the element 4, it may be deformed in various ways as long as it does not interfere with the normal transportation of the element 4.

(B) If the abnormal circuit elements 4a, 4b can be removed using the inclined surface 21, the claws 22 may be omitted.

(C) The engaging members 18 and 19 may be engaged with the element main body 1 without engaging with the lead wires 2 and 3. In this case, a single engaging member may be used.

(D) In the embodiment, the engaging members 18 and 19 are fixed, but after engaging the lead wires 2 and 3 of the abnormal circuit elements 4a and 4b, they are displaced in the direction of pushing down the lead wires 2 and 3. Good too. In this case, the lead wires 2 and 3 of the next element 4 are connected to the tip 2.
The tip 20 is returned to its original position before reaching the top of 0.
