DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a conveying device used in the manufacturing process of cylindrical electronic components such as fixed film resistors, capacitors, and diodes.

BACKGROUND ART Recently, so-called leadless cylindrical fixed film resistors, capacitors, diodes, and the like have been used. For example, in the case of a fixed film resistor, in the manufacturing process, caps r2 are fitted on both sides of the insulator r1, as shown in FIG.
A coating film r3 is formed on the insulator r1 as shown in FIG. 14B. Next, it is dried, and then, as shown in FIG. Obtainable.

03 is provided. Therefore, the conveyor belt 201
As the resistor element R1 travels, the resistance element R1 in the conveyance hole 202 is conveyed while being rolled on the guide rail 203. Therefore, dripping of the paint r3 applied to the outer periphery of the resistor element R1 can be prevented. Narrow relief holes 204 and 205 are connected to the conveyance hole 202 before and after the conveyance hole 202 in order to prevent the conveyance belt 201 from getting dirty with paint or the like when painting the resistor element R1. has been done.

Problems to be Solved by the Invention However, in the configuration of the conventional conveyor belt 201 as described above, each conveyor hole 202 is provided independently, so the front and rear escape holes 204, 205 and the uncut interval space 206, the total length of the conveyor belt 201 becomes longer. Therefore, in order to improve the manufacturing efficiency of resistors R, etc., it is necessary to increase the running speed of the conveyor belt 201, but if this running speed is made too high,
Not only is there a risk that the resistor element R1 and the like may bounce against the guide rail 203 and come out of the conveyance hole 202, but also supply troubles are likely to occur. Therefore the resistor R
There are limits to the improvement of manufacturing efficiency. Furthermore, the installation area of the factory becomes large, and its construction cost becomes high.Furthermore, the conveyor belt 101 itself becomes expensive, and therefore the manufacturing cost of resistors and the like becomes high.

The present invention can improve the manufacturing efficiency of cylindrical electronic components for resistors, can reliably transport the cylindrical electronic components, can prevent supply troubles, and can improve the production efficiency of cylindrical electronic components. It is an object of the present invention to provide a transport device for cylindrical electronic components that can reduce manufacturing costs and that can also reliably accommodate and transport cylindrical electronic components.

Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems is that long holes long in the running direction are arranged in a row at predetermined intervals, and a hole is inserted in the middle of each long hole. A plurality of transport holes for cylindrical electronic components are formed in a direction orthogonal to this elongated hole, arranged at a predetermined interval, and a detection hole for operating the supply device is provided on the side of each transport hole corresponding to each transport hole. an endless conveying body capable of reversing and running in a row, and a reversing drive device for driving this conveying body;
The guide rail is provided at the lower part of the carrier and guides the movement of the electronic component while the electronic component is housed in the carrying hole of the carrier.

Effect The effects of the above technical means are as follows.

The cylindrical electronic component inserted into the conveyor hole of the conveyor is transported while rolling on the guide rail by being driven by the reversing drive device of the conveyor, and during this conveyance, it is painted, color-coded, etc. Drying etc. can be performed. Since a plurality of conveyance holes are formed in a direction perpendicular to the elongated hole, a relief part is provided for each conveyance hole to prevent the conveyance body from being contaminated by paint etc. when painting cylindrical electronic components. A part of the elongated holes can be used both before and after the conveyance hole, and the interval between the conveyance holes can be narrowed.If the same number of conveyance holes as before are provided, the total length of the endless conveyance body can be shortened. I can do it. Therefore, when the conveyor is run at the same traveling speed as before, the manufacturing efficiency of cylindrical electronic components can be improved, and when the manufacturing efficiency is the same as before,
The traveling speed of the transport body can be slowed down, and the cylindrical electronic components can be transported reliably without bouncing off the guide rails and flying out of the transport hole.
Furthermore, the operation of supplying cylindrical electronic components to the conveyance hole can also be stabilized. Moreover, the installation area of the factory becomes smaller, the construction cost becomes cheaper, and the carrier itself becomes cheaper, so that cylindrical electronic components can be provided at low cost. In addition, by detecting the detection hole for the operation of the supply device, even if the pitch of the conveyance hole of the conveyor body is misaligned between the long holes, the timing of the conveyance hole and the supply device can be adjusted, and the cylindrical electronic component can be placed in the conveyance hole. It can be inserted securely.

The storage groove 4 of the resistance element R1 in the curved part
It can be pumped to the 3rd side. As the supply wheel 42 rotates intermittently, the resistor element R1 stored in the storage groove 43 is guided by the guide member 63 and sequentially transferred downward. As shown in FIGS. 6 and 7, the guide member 63 has a notch 66 formed at the lower end of the circumferential surface side, and when the resistor element R1 reaches this notch 66, it passes through the housing groove 43 and into the relief portion 5 of the conveyor 1. It falls on both sides of 6 and 7 or onto space 3. In this state, the resistance element R1 is restricted from moving in the axial direction by the side surface of the notch 66 of the guide member 63. Then, the position of the supply wheel 42 is finely adjusted by the adjustment screws 29 and 38 so that the position and interval between the storage groove 43 and the conveyor 1 are appropriate. As shown in FIG. 5, a recess 67 is formed on the lower surface side of the guide rail 15 at the position where the resistor element R1 falls, and a support member 68 mounted on the frame 9 is inserted into this recess 67.
A magnet 69 is mounted on the support member 68. The magnet 69 temporarily attracts and holds the resistive element R1, which has fallen onto the carrier 1 as described above, on the carrier 1. A stepping motor 45 is mounted on the upper part of the fixed plate 34 and the base of the arm 33.

Apply around the outside. A known means is also used for the drying position 23, and a heater (not shown) is provided in the drying oven 78, and this heater is connected to a temperature controller 79.
more regulated.

Next, the operation of the above embodiment will be explained. As described above, the resistor element R1 is supplied from the parts feeder 58 shown in FIGS. 3 and 4 to the storage groove 43 of the supply wheel 42 via the chute 57, 53. On the other hand, the transport body 1 is caused to travel by driving the motor 13. When the sensor 72 shown in FIGS. 5 and 6 detects the detection hole 8 of the carrier 1 as the carrier 1 travels, the stepping motor 45 is driven, the supply wheel 42 rotates, and the resistor element R1 is rotated. Transport. When the sensor 50 detects the groove of the timing cam 48, the stepping motor 45 is stopped.
When the sensor 72 detects the next detection hole 8, the stepping motor 45 is driven, and this operation is repeated to transfer the resistive element R1 in the storage groove 43 to the lower part of the guide member 63. And in this state sensor 7
2 similarly detects the next detection hole 8, the stepping motor 45 is driven, the supply wheel 42 rotates, and the resistor element R1 in the storage groove 43 is thereby driven.
falls from the notch 66 of the guide member 63 onto the space 3 of the carrier or on both sides of the relief portions 5, 6, and 7, and is attracted and held by the magnet 69. At this time, the sensor 50 detects the groove of the timing cam 48, and upon this detection, the driving of the stepping motor 45 is stopped. Since the resistance element R1 that has fallen onto the conveyor 1 is held in the notch 66 of the guide member 63, when the conveyor hole 4 of the traveling conveyor 1 is located below it, the inside of this conveyor hole 4 is held. The cap r2 is supported on the guide surface 17 of the guide rail 15. During this time, the resistance element R1 is moved to the guide member 63.
Since the movement of the notch 66 in the axial direction is restricted by both sides, the notch 66 will surely fall into the conveyance hole 4. When the sensor 72 detects the next detection hole 8 as the conveyor 1 travels, the stepping motor 45 is driven, and the same operation as described above is repeated, causing resistance to the conveyor hole 4 of the traveling conveyor 1. The element bodies R1 can be sequentially supplied. As described above, the supply device 21 drops the resistance element R1 vertically in the chute 57, 53, changes its posture horizontally at the lower part of the chute 53, and then drops the resistor element R1 vertically in the chute 53, changing its posture to horizontally at the lower part of the chute 53, and inserts it into the storage groove 4 of the supply wheel 42.
3, by transporting it sideways and letting it fall, clogging in the chute 57, 53 can be prevented. However, if the supply wheel 42 is always rotated intermittently at a constant speed, the conveyance holes 4 are shifted so that the pitch becomes longer between the long holes 2, so that the resistor element R1 cannot be reliably supplied to each conveyance hole 4. I can't. Therefore, in the present invention, since the supply device 21 is operated by the detection of the detection hole 8 as described above, the operation timing of the supply device 21 can be easily matched with the conveyance hole 4, and the resistance element The body R1 can be reliably supplied to the conveyance hole 4. Therefore, the carrier 1 is the resistive element R1
can be reliably stored and transported.

The resistance element R1 supplied to the conveyance hole 4 is transferred to the conveyor 1
As the material travels, it is conveyed while rolling on the guide rail 15 and the guide surface 17. During this conveyance, as shown in FIG. Paint film r on the outer periphery between
3 is formed. At this time, since relief portions 5, 6, and 7 are formed before and after the conveyance hole 4, it is possible to prevent paint from adhering to the conveyance body 1. Since the front and rear relief portions 6 of the conveyance hole 4 formed in each elongated hole 2 are also used, the dead space is limited to the space 3 between the elongated holes 2 and the front relief portion 5 or the rear relief portion 7. Therefore, the interval between the conveyor holes 4 at the two long hole positions can be narrowed, and when forming the same number of conveyor holes 4 as in the past, the overall length of the conveyor 1 can be made significantly shorter than in the past. can do.

The resistor element R1 after painting is transferred to the carrier 1 as described above.
Since the paint is conveyed while rolling on the guide surface 17 of the guide rail 15, dripping of the paint is prevented and the paint is dried by the drying device 23. Also in this drying process, since the intervals between the conveying holes 4 are narrow as described above, the drying device 23 can also be shortened if the drying time is the same as the conventional drying time. The resistor element R1 after drying falls into the receiving box 24 through the opening of the guide rail 15.
