Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for transporting electrical parts, and more particularly, to a transport apparatus for cylindrical chip parts.

In recent years, parts called cylindrical chip parts that do not have lead wires have appeared. Unlike parts with leads, these types of parts cannot be subjected to various processes in the manufacturing process using lead wires.

For example, during the painting and subsequent drying processes, parts cannot be supported using lead wires, so a separate device must be developed for processing cylindrical chip parts.

The present invention has been made in view of the above points, and an object of the present invention is to provide an apparatus that can transport cylindrical chip components while performing predetermined processing.

To achieve this objective, the present invention includes an endless belt in which through holes through which cylindrical chip parts can pass are formed at a predetermined pitch, and nine rails arranged below the belt at predetermined intervals. By moving the belt, the through holes of the belt and the rails cooperate to form a wire for conveying the parts.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

HIFIJ is constructed as a coating device and shows the overall configuration of an embodiment of the present invention. In the figure, l is an endless belt, and a flat belt wheel 2.3 and a guide member Kjl between these belt wheels are installed. , the guide member with 〇 that runs along the belt pulley 2゜3 and the guide member between these belt wheels by the drive #5 provided on the belt pulley 3 is the rail 4 in the upper belt passage,
Contact and guide the belt at both side edges of the belt. The lower belt path is also provided with several guide rollers.

Since the cylindrical chip parts to be conveyed have iron caps, they are made of stainless steel to avoid magnetism. On the running path of the belt 1, which is kept constant at all times by The cylindrical chip parts (painted and dried) are also coated on this travel path, and there is a demagnetizer 8 for demagnetizing the iron cap of the cylindrical chip parts, and paint that adheres to the back side of the belt 1. A rotating brush 7 is provided for removing the particles.

The operation of this coating device is controlled by a control panel 12, and the dried products are counted by a counter 13 and sent to the after cure 2]. The after-cure 21 transfers the cylindrical chip components using the driving source B and performs necessary processing such as cooling. The main components of this mechanism are a hopper 101, a parts feeder 103, and a turntable 105, which aligns sorted cylindrical chip parts that have been randomly placed into the hopper 101, and horizontally aligns them on the t. It has the function of dropping one piece at a time onto the general feeding member formed by the belt 1 and rail 4.

That is, the hopper 101 supplies cylindrical chip parts to the parts feeder 1'03 by actuating a reit switch using a lever 102 provided on the parts feeder 103. Also, the parts feeder 103 has a chute 104.
A sensor 107 provided near the turntable 105 of
The cylindrical chip parts can be read into Kuwait 104 one by one until the detection of . The cylindrical chip component that fell straight inside the shade 104 is the turntable 1.
The turntable 105 fits into a large circle provided around the periphery of the belt 1 without changing its posture.The turntable 105 is fed in steps according to the detection output of the sensor 106 that detects holes in the belt 1, and is fed along the periphery of the turntable. A cylindrical chip component is dropped into the through hole of the belt 1. Below the belt 1 there is a rail 4, by which the iron caps at both ends of the cylindrical chip component are received.

What should be noted here is that the turntable 105 is configured in the shape of a bevel gear, and has a component insertion hole at its periphery that is inclined at 45 degrees with respect to the axial direction. This means that it has been installed.

With this configuration, the nine cylindrical electric components that fall vertically are turned horizontally and dropped into the through holes of the belt 1.

Fig. 3 (a), (b) id turntable 105
This figure shows the detailed structure of the turntable 105 and the structure of the cam plate that controls the stepping operation of the turntable 105.

The turntable 105 has a supply drum 105&, an index 105b, and a magnet case 105ot,
It is driven by a stepping motor 108. and,
This stepping motor 108 has, for example, 9
Based on the cam plate 109 provided with slits at intervals of .degree., the turntable 1050 is controlled to be energized so as to rotate one component insertion hole at a time.

FIG. 4 shows the shape of the belt 10 through-hole.

The material of the belt 1 is stainless steel, and the through holes 1 are sequentially arranged at a predetermined pitch p in the center of the belt in the longitudinal direction.
It has a. The width of this through hole 11 is slightly larger than the length of the cylindrical chip component shown by the phase image line, and the length is selected so that the center part is large 1 and the both sides are short <Ll. .

The reason why the central part is large is to prevent the coating roller from coming into contact with the belt [K base (Fig. The rail can be divided into any number of unit structures in the longitudinal direction, and here only the main part of one unit structure is shown.0 As shown, belt 1 is a belt. Width position regulation bearing 2
01, both ends in the width direction are guided by the belt pressing member 202 and the rail 4 in the thickness direction.

The longitudinal end of the rail 4 engages with a rail clamper 203 to prevent the rail from warping due to thermal expansion. And rail 4 is rail clamper 20
4 is fixed to the next rail, forming one long rail. The component supply side of this rail is fixed, and the opposite end is free, allowing thermal expansion to escape in one direction. This means that if there is a gap between the rails, the cylindrical chip component will fit into that gap. Fig. 7 (6L), (c), and Fig. 8 show the structure of a coating device that applies undercoat and topcoat to the parts of cylindrical chip parts except for the iron cap part. It shows in detail,
This is similar to the coating device 10 shown in FIG.

In this device, a rubber roller 302 having a groove in the widthwise center of the circumferential surface presses the part This is done by rotating. In this case, since the iron cap part of the cylindrical chip component is used as a terminal, care must be taken to ensure that the paint does not get on the cap part. Therefore, the thickness of the portion of the coating roller 402 that comes into contact with the component X needs to match the length of the portion of the component X excluding the middle body portion, that is, the cap portion.

This paint roller 402 is driven by a motor 401 and removes the paint pulled up from the paint can 403 onto a paint scraping table 404.
Adjust the amount with and apply part XK.

This painting is done twice: a base coat and a top coat.

Figures 9(a), (b), (a) and Figure 10 are specific examples of the prescribed equipment for coating color codes such as resistance value, capacitance, error rate, polarity, etc. after coating with undercoat and topcoat lines. 0 This coating device is installed in a color code coating line having the same configuration as the coating line shown in FIG. 1II, for example, and can be replaced with the coating device 10 in FIG. .

This coating device is shown for coating four color codes, and a motor 501 drives four rubber rollers 502.
The four coating rollers 602 are rotated by the motor 601. 603 is a paint can, and 604 is a paint caster.

In the above embodiment, the coating equipment is provided separately for the undercoating and topcoating lines and for the color code coating line, but it is of course possible to configure these units in series.

Also, add one more line for resin painting before undercoating.
As described above, in the present invention, cylindrical chips are conveyed so that they can be coated by the cooperation of an endless belt with through holes formed at a predetermined pitch and a rail below the belt. Therefore, the manufacturing efficiency of cylindrical chip parts can be greatly improved.
