Field of the Invention The present invention relates to a device for detecting the front and back of rubber for packing an electrolytic capacitor, and more particularly to a device for manufacturing an electrolytic capacitor in which the front and back of the packing rubber having a stepped portion for bleeding air on one end surface are aligned. The present invention relates to a technique for discriminating between the front and back of a packing rubber which is gripped and conveyed by a gripping means for supplying.

[0002]

2. Description of the Related Art As a packing rubber for an electrolytic capacitor, one having an air venting function as shown in FIGS. 7 (a), 7 (b) and 7 (c) is used. Figure 7
In the packing rubber, substantially semi-cylindrical stepped portions 3a, 3b facing each other are formed integrally with the main body 1 on one circular end surface of the cylindrical main body 1. Two lead wire insertion holes 7a and 7b penetrating the main body 1 are formed in the gap 5 between the stepped portions 3a and 3b.

Such a packing rubber is fitted into the bottom of a cylindrical aluminum case having an electrolytic capacitor body housed therein to pack the aluminum case. In this case, the stepped portions 3a and 3b of the packing rubber are arranged so as to be positioned toward the outside of the electrolytic capacitor. As a result, when the electrolytic capacitor is mounted on the printed circuit board,
A gap is formed between the printed circuit board and the electrolytic capacitor, so that it becomes possible to appropriately discharge the flux, the air, etc., which are present between the electrolytic capacitor and the printed circuit board, during the solder reflow process or the like.

As shown in FIG. 8, the packing rubber having such an air bleeding step portion is fitted into the holes provided at predetermined intervals in the carrying tape 11 and supplied to the electrolytic capacitor manufacturing apparatus. To be done. The transport tape 11 is
For example, it is formed of flexible plastic, polyethylene or the like. When the packing rubber 9 is mounted on the transport tape 11, the packing rubber 9 is mounted so that the air bleeding stepped portions 3a and 3b are on the upper side. The packing rubbers 9 are mounted so that the direction of the gap 5 between the air bleeding stepped portions is constant, for example, aligned in the length direction of the carrier tape 11. These conditions are required for the packing rubber 9 to be incorporated in the electrolytic capacitor at an appropriate position and direction in the electrolytic capacitor manufacturing apparatus.

By the way, in order to mount the packing rubber 9 on the carrying tape 11 with the front and back aligned, the packing rubber 9 should be aligned with each other in advance and near each mounting hole of the carrying tape 11. It is necessary to convey the packing rubber 9. For this reason, it is necessary to detect the front and back of the packing rubber 9 and eliminate the one that has been conveyed with the front and back reversed.

FIG. 9 schematically shows a front / back detecting mechanism conventionally used for such a purpose. In the mechanism shown in the figure, the front and back of the packing rubber 9 are determined by pressing the detection pin 15 against the packing rubber 9 placed on the base 13. That is, the detection pin 15 is provided with a protruding portion 17 having a width narrower than the width of the gap portion 5 between the stepped portions of the packing rubber 9 at the tip portion. The detection pin 15 is fitted in the through hole 21 of the arm 19 and is urged downward by the coil spring 23 with respect to the arm 19. A proximity sensor 25 is provided at the upper end of the detection pin 15. Proximity sensor 2
Reference numeral 5 outputs an instruction signal, for example, a signal indicating that the front and back sides are reversed when the detection pin is magnetically or optically located at a position facing the sensor 25.

In the mechanism of FIG. 9, the protrusion 17 of the detection pin 15 is pressed against the packing rubber 9 placed on the base 13 by moving the arm 19 downward. Therefore, when the packing rubber 9 is placed on the base 13 with the air bleeding step up, the normal condition is that the protruding portion 17 of the detection pin 15 has the gap of the packing rubber. The position of the pin 15 is lowered as it enters the portion 5. Therefore, the proximity sensor 25
From this, it can be seen that the signal indicating the proximity of the pin 15 is not output, and therefore the packing rubber 9 is normally placed on the base 13. Note that the packing rubber 9 has the gap 5 in a predetermined direction, that is, the detection pin 1 in advance.
The angle is adjusted by an angle correction device (not shown) so as to coincide with the direction of the protrusion 17 of No. 5.

On the other hand, as shown in FIG.
When the packing rubber 9 is placed on the base 13 with the stepped portion facing downward, the protrusion 17 of the detection pin 15 contacts the back surface of the packing rubber 9, and the position of the entire detection pin 15 is changed. Get higher Therefore, the proximity sensor 25 outputs a signal indicating the proximity of the detection pin 15, that is, a signal indicating that the packing rubber 9 is placed in the inverted state.

[0009]

In the above-mentioned conventional detection mechanism, the packing rubber 9 is pressed by the protrusion 17 of the detection pin 15 to press the packing rubber 9.
In order to determine the front and back sides, the rubber may be crushed due to pressure, resulting in erroneous detection. In particular, erroneous detection often occurs with a smaller packing rubber or a smaller stepped portion.

Therefore, an object of the present invention is, in view of the above-mentioned problems in the front and back detecting mechanism of the conventional example, in the front and back detecting device for the packing rubber of the electrolytic capacitor, the influence due to the collapse of the packing rubber is eliminated and the front and back are more accurate. It is to realize a front and back detection device capable of detecting

[0011]

In order to achieve the above object, according to the present invention, an air bleeding step having first and second end faces, which face each other with a gap portion sandwiched between the first end faces. A front and back detecting device for discriminating the front and back of the packing rubber of the electrolytic capacitor which is carried by the gripping means and which is aligned and carried so that the gap part is aligned with the carrying direction. From the top surface of the fence-shaped protrusion of the fixed guide, which is formed along the fixed guide having a fence-shaped protrusion that is narrower than the width of the gap of the packing rubber, Surface parallel to the feeding surface of the packing rubber at a position that is larger than the thickness between the end surfaces and is smaller than the thickness from the second end surface to the end surface of the stepped portion of the first end surface. In providing a detection lever movable, and a sensor which outputs the front and back instruction signal in response to the movement of the detection lever.

In this case, it is preferable that the fence-shaped protruding portion of the fixed guide has a small protruding amount on the introduction side of the gap portion of the packing rubber.

Further, it is preferable that the fence-shaped protruding portion of the fixed guide is formed so as to have a narrow width on the introduction side of the gap portion of the packing rubber.

Further, the gripping means may convey the packing rubber along an arc around a predetermined rotation center, and the fence-shaped protrusion of the fixed guide may be formed along the arc.

[0015]

In the front and back detecting device for the packing rubber of the electrolytic capacitor according to the above configuration, when the packing rubber is conveyed with its stepped portion facing the fixed guide side, the fixed guide protrudes like a fence. Since the portion enters the gap portion of the packing rubber, the second end surface passes through the fixed guide portion without contacting the detection lever. On the other hand, when the stepped portion of the packing rubber is conveyed so as to face the side opposite to the fixed guide, the second end surface contacts the top surface of the fence-shaped protrusion of the fixed guide and moves the guide portion. The stepped portion provided on the first end face abuts on the detection lever to move the detection lever, thereby outputting a signal indicating that the sensor is upside down.

In such an operation, since there is no member for pressing the packing rubber, erroneous detection due to the collapse of the rubber is completely eliminated. Further, by adjusting the distance from the top surface of the fence-shaped protrusion of the fixed guide to the detection lever, it is possible to easily deal with packing rubber of various sizes.

Further, the wall of the fixed guide having the fence-shaped protruding portion is provided with a small amount of protrusion and / or a narrow width on the introduction side of the gap portion of the packing rubber so that the packing rubber is conveyed. It becomes possible for the gap portion of the rubber to smoothly fit into the wall of the fixed guide and pass through the fixed guide portion without being caught. This improves the reliability of the front / back detection device.

Further, the gripping means is configured to convey the packing rubber along an arc around a predetermined rotation center, and the fence-shaped protrusion of the fixed guide is formed along this arc to fix the rubber. The fence-shaped protruding part of the guide can be provided so as to be precisely aligned with the conveying path of the packing rubber, eliminating the jamming of the packing rubber and other inconveniences, enabling high-speed front and back detection and reliability of the device. The property is also improved.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic configuration of a taping device that includes a packing rubber front and back detecting device according to an embodiment of the present invention, and that mounts the packing rubber on a carrying tape. The apparatus shown in FIG. 1 includes a parts feeder 101 for supplying packing rubber, a carrying device 103 for carrying the packing rubber to perform front and back detection described later, and a height adjusting device for matching the height of the packing rubber during carrying. 10
5, an angle adjusting device 107 for adjusting the angle of the gap portion with respect to the conveying direction of the packing rubber, a front / back detecting device 109 for detecting the front and back of the packing rubber, and a reverse rubber removing device 111 for removing the packing rubber which is the reverse of the front and back,
Further, a mounting device 113 for mounting the packing rubber on the transport tape 11 is provided.

The parts feeder 101 is for supplying a large number of packing rubbers 9 put into the tray 115 in the central part in a continuous manner along the guide rails 117. Such a parts feeder has a conventional structure. It is more well known. The cross section of the guide rail 117 is a quadrangle having a size through which the packing rubber 9 can sufficiently pass, and an observation gap is provided on the upper portion thereof. The guide rail 117 extends from a circular portion formed along the periphery of the pan 115 to a straight portion that extends horizontally in the right lateral direction in the drawing. At the end of the straight portion of the guide rail 117, the packing rubber 9 coming out from the guide rail 117 is held and can be moved in the arrow A direction or the opposite direction so as to be fed to the height adjusting device 105. Transport arm 1
19a and 119b are provided. These arms 1
19a and 119b linearly convey the packing rubber 9 from both sides to the position of the height adjusting device 105. After the conveyance, it returns to the end of the guide rail 117 and holds the next packing rubber 9. Therefore, these arms 119a and 119b are driven by an actuator (not shown) to perform these operations. As the actuator, various actuators such as a pneumatic actuator and an electromagnetic actuator can be used.

The transfer device 103 is provided with a disk member 123 which is rotatable around a rotary shaft 121 in the direction of arrow B. Two holding arms 125a and 125b for holding or holding the packing rubber are attached to the disc member 123. The holding arms 125a and 125b are operated by an actuator (not shown) to hold the packing rubber 9 from both sides or release the holding. The holding arms 125a and 125b rotate together with the rotation of the disk member 123 to sequentially move the packing rubber 9 to each device.

The height adjusting device 105 is supplied from the parts feeder 101 and has the conveying and holding arms 119a and 119b.
The height of the packing rubber sent by is adjusted so that the packing rubber is held by the holding arms 125a and 125b at a preset reference height. The operation of the height adjusting device 105 will be described later in detail.

The angle adjusting device 107 is a height adjusting device 10.
5, holding arms 125a, 125b at a predetermined height
The direction of the gap 5 of the packing rubber 9 sandwiched and conveyed by the packing rubber 9 is aligned with the conveying direction of the packing rubber 9, that is, the circumferential direction of a circle around the rotation shaft 121. This device may rotate the packing rubber 9 so that the lead holes 7a and 7b of the packing rubber (FIG. 7) are aligned in the carrying direction.
In this case, for example, an optical sensor consisting of a light source and a photodiode is arranged at the positions of the lead holes 7a and 7b along the direction in which the packing rubber is conveyed, and the photodiodes of the respective optical sensors pass through the lead holes 7a and 7b. The angle of the packing rubber is aligned by rotating the packing rubber 9 at such an angle that the detected light can be detected.

Next, the front and back detecting device 109 will be described in detail later, but a fixed guide 129 provided with a wall-shaped protruding portion 127 formed along the conveying direction of the packing rubber 9, a detection arm 131, and a sensor 133. Etc. When the stepped portions 3a and 3b of the packing rubber 9 are conveyed upward in the plane of the drawing, the gap 5 of the packing rubber 9 fits into the fence-shaped protrusion 127 and passes therethrough. The position of the lower surface of 9 passes a position higher than the detection lever 131. Therefore, the detection lever 131 does not move, the sensor 133 does not output a signal indicating the reversed state of the packing rubber 9, or outputs a signal indicating that the direction of the packing rubber 9 is normal. On the other hand, when the packing rubber 9 is conveyed in the stepped portions 3a and 3b below the paper surface, that is, in the direction farther than the fixed guide 129, the packing rubber stepped portions 3a and 3b are formed. The flat end face is conveyed while being in contact with the fence-shaped protruding portion 127, so that the stepped portions 3 a and 3 b come into contact with the detection lever 131. As a result, the detection lever 131 is rotated counterclockwise, and the sensor 133 outputs a signal indicating that the front and back are reversed, or does not output a signal indicating that the sensor is normal.

Next, the reversal rubber removing device 111 further mounts the packing rubber 9 conveyed by the holding arms 125a and 125b on the basis of the signal given from the sensor 133 of the front and back detecting device 109 without further processing.
It is selected whether the sheet is conveyed to the No. 13 or is pushed down into the rubber receiving container 141. Therefore, the reverse rubber excluding device 11
1 includes an exclusion pin (not shown) and an actuator that operates the exclusion pin. The actuator presses an exclusion pin against the packing rubber 9 when the packing rubber 9 is conveyed in the reverse state on the basis of a signal from the sensor 133 of the front and back detection device 109, and the holding arm 1
It is pushed down into the rubber receiving container 141 from 25a and 125b.

The mounting device 113 includes a holding arm 125a,
The packing rubber 9 which is normally held in a desired direction, that is, desired by 125b, and conveyed is pressed from above and fitted into each hole 143 of the conveyance tape 11. For this reason, the mounting device 113 includes an actuator and a pressing pin (not shown), and when each hole 143 of the transport tape 11 is set at a desired position, the pressing pin is operated to move the packing rubber 9 into the hole 143. Inset.
The transport tape 11 is sequentially moved by, for example, a pulse motor so that the holes 143 come to the mounting position of the mounting device 113.

As described above, in the apparatus shown in FIG. 1, the packing rubber 9 sequentially fed from the parts feeder 101 to the guide rail 117 is used to convey and hold the holding arms 119a and 11a.
It is nipped by 9b and conveyed to the position of the height adjusting device 105. Then, the height adjusting device 105 holds the packing rubber conveyed by the conveying and holding arms 119a and 119b by the two pins arranged in the vertical direction to adjust the height. After the height is adjusted, packing rubber 9
Is held by the holding arms 125 a and 125 b of the transfer device 103 and transferred to the angle adjusting device 107. In the angle adjusting device 107, the stepped portion 3a of the rubber 9 for packing,
The direction of the gap 5 between 3b is the rubber 9 for packing.
The angle is adjusted so as to coincide with the conveyance direction of. Then, the front and back detection device 109 determines the front and back of the packing rubber 9 conveyed from the angle adjusting device. When it is transported to the place, it is removed into the rubber receiving container 141. The packing rubber that has been conveyed in the normal direction passes through the portion of the reverse rubber elimination device 111 and is conveyed to the mounting device 113. In the mounting device 113, the packing rubber 9 is sequentially fitted into the holes of the transport tape 11 in the normal direction. The carrying tape 11 thus fitted with the packing rubber 9 is supplied to an electrolytic capacitor manufacturing apparatus (not shown) and used for packing the electrolytic capacitor.

A control unit (not shown) is provided to control the operation of each unit as described above, and the control unit is composed of a microcomputer and its control program.

FIG. 2 shows an example of the configuration and operation of the height adjusting device 105. The apparatus shown in FIG. 2 includes two holding members 145 and 147 for sandwiching the packing rubber 9 conveyed by the conveying and holding arms 119a and 119b of the parts feeder 101 from above and below to adjust the height. The holding members 145 and 147 have, for example, a cylindrical shape, and hollow portions 149 and 151 are formed inside.
These cavities 149 and 151 have a circular cross section, the diameter of which is smaller than the outer diameter of the main body 1 of the rubber 9 for packing, and the stepped portions 3a and 3b can be accommodated inside. Further, the holding members 145 and 147 are respectively provided with the pin 1
It is connected to an actuator (not shown) by 53 and 155, and is configured to be movable in a predetermined vertical direction.

A process in which the height of the packing rubber 9 is adjusted by such a height adjusting device will be described. First, as shown in FIG. 2A, the parts feeder 1
The carrying nip arm 119a, 119b of 01 causes the packing rubber 9 to hold the holding members 145, 14 of the height adjusting device.
It will be transported to 7 locations.

Next, as shown in (b), an actuator (not shown) is operated and the holding members 145 and 147 hold the packing rubber 9 from the upper side and the lower side, respectively. At this time, the stepped portions 3a and 3b of the packing rubber enter into the hollow portions 149 or 151 of either holding member 145 or 147. Therefore, the holding member 14
5, 147 holds the packing rubber 9 on the upper and lower circular end surfaces of the main body 1.

Next, the conveying pinching arms 119a and 119b from the parts feeder 101 widen their intervals to release the pinching of the packing rubber 9, and the parts feeder 1 again.
01 Return to the end of the guide rail 117. In this state, an actuator (not shown) of the height adjusting device 105 is operated to move the holding members 145, 147 upward, for example, by a predetermined distance so that any circular end surface of the main body 1 of the packing rubber 9 becomes the reference surface. Height adjustments are made to position it. FIG. 2C shows a state in which such height adjustment is performed. In this figure, the alternate long and short dash line T indicates the position of the reference plane.

Next, in this state, the transport device 103 (FIG. 1)
The holding arms 125a and 125b of the
Hold from both sides. Then, the actuator (not shown) of the height adjusting device 105 is actuated to operate the holding members 145, 1
47 is moved to the upper side and the lower side respectively, and the holding of the packing rubber 9 is released. FIG. 2D shows this state, in which the height of the packing rubber 9 is adjusted and the conveying device 10 is adjusted.
3 shows a state of being held by three holding arms 125a and 125b. The state of FIG. 2A shows a normal state in which the stepped portions 3a and 3b of the packing rubber 9 are held upward. On the other hand, FIG. 2 (e) shows a front-back reversal state in which the stepped portions 3a and 3b of the packing rubber 9 are sandwiched in the downward direction. In this way, the height of the packing rubber 9 adjusted by the nipping arms 125a and 125b is sent to the angle adjusting device 107 (FIG. 1), and the direction of the gap 5 is adjusted.

FIG. 3 shows the construction of a front / back detection device 109 for detecting the front / back of the packing rubber 9 conveyed from the angle adjusting device 107. The front / back detection device 109 of FIG.
The stationary guide 129 is formed of an arc-shaped member having a square cross section, for example. On the lower surface of the fixed guide 129, a fence-shaped protruding portion 127 is provided along the conveyance route of the packing rubber 9.
Are formed. The width of the fence-shaped protrusion 127 is smaller than the width of the gap 5 of the packing rubber 9. The height of the top surface of the wall-shaped protruding portion 127, that is, the bottom surface in this case, is parallel to the conveying surface of the packing rubber 9.

The detection arm 131 is provided at a predetermined distance from the bottom surface of the fence-shaped protrusion 127 of the fixed guide 129. The detection arm 131 is rotatable about the rotation shaft 135 in a plane parallel to the transport surface of the packing rubber 9. Further, the portion of the packing rubber on the conveying path side is biased clockwise by the coil spring 137. A stopper pin 139 for stopping and positioning the detection pin 131 is provided in opposition to this bias. At the other end of the detection arm 131, a sensor 133 composed of a photo interrupter or the like is provided. The sensor 133 has a gap portion 153, and is configured to output a predetermined instruction signal when the detection pin 131 enters the gap portion 153. The other end of the detection arm 131 is usually arranged outside the gap part of the sensor 133, and when the detection lever 131 separates from the stopper pin 139 and rotates clockwise, it enters the gap part 153. Has been done.

More importantly, the distance from the bottom surface of the fence-shaped protruding portion 127 of the fixed guide 129 to the upper surface of the detection lever 131 is longer than the distance between both end surfaces of the packing rubber main body 1 and It is configured to be shorter than the distance from the end surface of the stepped portion of the rubber 9 to the end surface of the main body 1 on the side not having the stepped portion. Therefore, the distance from the bottom surface of the fence-shaped protruding portion 127 to the upper surface of the detection lever 131 is set according to the height of the packing rubber for performing front / back detection. This distance may be adjustable to detect the front and back of various packing rubbers.

With this structure, the packing rubber 9 nipped by the holding arms 125a and 125b from the angle adjusting device 107 and conveyed has the stepped portions 3a and 3b facing the fixed guide 129. When it is conveyed in a normal state, the gap portion 5 of the stepped arm 9 passes by sandwiching the fence-shaped protruding portion 127, and therefore the gap between the lower surface of the packing rubber 9 and the detection lever 131. A gap is formed, and the packing rubber 9 passes through the fixed guide 129 without contacting the detection lever 131. FIG. 3B shows this state.

On the other hand, as shown in FIG.
When the stepped portion of the conveyed packing rubber 9 faces the side farther than the fixed guide 129, the stepped portion of the packing rubber 9 is formed on the bottom surface of the fence-shaped protrusion 127 of the fixed guide 129. The fixed guide 129 is conveyed while contacting the end surface on which is not formed. Therefore, the stepped portions 3a and 3b of the packing rubber 9 are not attached to the detection lever 131.
And the detection lever 131 is rotated counterclockwise. This causes the other end of the detection lever 131 to enter the gap portion 153 of the sensor 133, and the sensor 133 outputs a signal indicating that the sensor is upside down. FIG. 3C shows this state.

FIG. 4 shows the fixed guide 129 used in the apparatus of FIG. 3 in an upside down state. As is clear from FIG. 4, the fence-shaped protrusion 127 of the fixed guide 129 has a fence-shaped protrusion 127 formed at a constant height along the conveying path of the packing rubber 9. However, on the inlet side where the packing rubber 9 reaches first, the fence-shaped protrusion 1
The height of 27 is configured to gradually increase from the inlet side toward the inside. Further, the width of the fence-shaped protruding portion 127 is also narrower on the inlet side than other portions. This is the gap 5 of the packing rubber 9 being conveyed.
This is for easily engaging with the wall-shaped protrusion 127.

FIG. 5 shows the packing rubber 9 in the normal direction.
The positional relationship among the packing rubber 9, the fixed guide 129, and the detection lever 131 when the paper is conveyed is shown.
When the packing rubber 9 is conveyed in the normal direction as shown in FIG. 6A, the gap portion formed between the stepped portions of the packing rubber 9 is formed as shown in FIG. The fixed guide 129 is conveyed so as to sandwich the fence-shaped protrusion 127. Therefore, the lower surface of the packing rubber 9 does not come into contact with the detection lever 131. Therefore,
The detection lever 131 does not move, and the packing rubber 9 passes through the fixed guide 129 as it is.

FIG. 6 shows how the packing rubber 9 is conveyed with its front and back reversed. In this case, when the packing rubber 9 is conveyed toward the fixed guide 129 as shown in FIG. 9A, a stepped portion of the packing rubber 9 is provided as shown in FIG. The end surface on the non-contact side is conveyed while abutting on the bottom surface 155 of the fence-shaped protrusion 127. Therefore, the stepped portion of the rubber 9 for packing comes into contact with the detection lever 131 to rotate the detection lever 131. As a result, the sensor 133 outputs an instruction signal indicating that the sensor is upside down.

[0042]

As described above, according to the present invention, since the packing rubber is not pressed by the detection pin as in the conventional case, the rubber is not crushed. Therefore, even if the packing rubber has a particularly small stepped portion, it is possible to detect the front and back sides extremely accurately without being adversely affected by the rubber collapse. Further, according to the present invention, the front and back of the packing rubber that is sequentially conveyed can be accurately detected continuously and at a high speed, so that the production efficiency and speed of the electrolytic capacitor can be significantly increased. .
