【Example】

 1 to 9 show an embodiment of the present invention. FIG. 1 is a sectional view of an article supply device, FIG. 2 is an enlarged view of a main part of FIG. 1, FIG. 3 is a perspective view of a magazine, and FIG. FIG. 5 is a perspective view of the mechanism, and FIGS. 5 to 9 are explanatory diagrams of the operation.

First, the configuration of the article supply apparatus will be described with reference to FIGS. 1 to 4. The article supply device shown in the figure is intended to supply an IC (hereinafter referred to as an article P) having a rectangular flat outline package, and is composed of an apparatus main body 1, a magazine 11, and an pushing mechanism 21. It is configured.

The apparatus main body 1 has a horizontal guide groove 2 having a sectional shape slightly larger than the width and thickness of the article P on its upper surface in a linear shape, and a magazine 11 to which a magazine 11 is detachably mounted. The support portion 3 is provided on the front upper portion of the guide groove 2. Further, an optical sensor 4 such as a phototransistor which is activated by the incidence of external light is embedded in the bottom surface of the front end of the guide groove 2 through a light passage hole 4a.

As shown in FIG. 2, the magazine supporting portion 3 is provided with a mounting hole 3a penetrating therethrough, which has a cross-sectional outer shape of the magazine 11 and is inclined by about 60 ° with respect to the vertical line. On the lower surface of the hole 3, a step portion 3b that engages with the lower edge of the outlet of the magazine 11 is formed. Further, in front of the mounting hole 3a, there is a horizontal clearance slightly larger than the lower end opening of the mounting hole 3a and the length of the article P, and slightly larger than the bottom surface of the guide groove 2 and the thickness of the article P. A vertical wall 3c having a vertical clearance is formed. The article P flowing out from the magazine 11 comes into contact with the vertical wall 3c, the position and the direction of the article P are corrected, and the article P is dropped onto the guide groove 2.

The magazine 11 has a vertically long storage space 12 therein, one end of the space 12 is opened as an outlet 13, and a large number of articles P are stored side by side in the storage space 12. .. As shown in FIG. 3, the magazine 11 of the illustrated example has a vertically elongated magazine body 14 having a concave portion 14a having a sectional shape slightly larger than the width and thickness of the article P, and is rotated to one side edge of the magazine body 14. The opening / closing plate 15 is freely attached, and the articles P can be stored by opening the opening / closing plate 15, and the opening / closing plate 15 can be closed by a magnet 16 and a metal piece 17. The magazine 11 is mounted on the apparatus main body 1 by inserting its outlet portion into the mounting hole 3 and engaging the lower edge of the outlet 13 with the step portion 3b.

As shown in FIG. 4, the push-out mechanism 21 includes a push-out arm 22, a drive arm 23, a cam 24, and a motor 24, and is arranged at the rear portion of the apparatus main body 1. There is. The extrusion arm 22 has a vertically long flat plate shape and has a recess 22a on the upper surface of the front end portion and an operation pin 22b made of a ferromagnetic metal on the upper surface of the rear end portion. It is movably arranged. The drive arm 23 has a vertically long flat plate shape, holds the operation pin 22b slidably and rotatably in a long hole 23a formed from a front end portion to a substantially middle portion, and also sucks the operation pin 22b. Has a magnet 23b for use at the front end. The cam 24 is formed by providing an eccentric shaft 24a on a disk component, and the rear end portion of the drive arm 23 is rotatably supported on the eccentric shaft 24a. The motor 25 includes a speed reducer 25a, and the output shaft of the speed reducer 25a is connected to the central portion of the cam 24.

In the push-out mechanism 21 described above, by rotating the cam 24 in a predetermined direction by the motor 25, the rotational movement of the cam 24 is converted into a linear movement by the drive arm 23 and operated by the magnet 23b. The push-out arm 22 having the pin 22b adsorbed and held therein can be moved forward or backward in the guide groove 2. Further, when a resistance exceeding the attraction holding force of the magnet 23b acts on the pushing arm 22 when the pushing arm 22 moves forward, the operating pin 22b is slid along the elongated hole 23a, and the pushing arm 22b is slid. 22 can be retracted relative to the drive arm 23.

Next, with reference to FIG. 1 and FIGS. 5 to 9, the handling and supply operation of the above-described article supply apparatus will be described.

Before the supply of the articles P, the magazine 11 is first attached to the apparatus main body 1. Specifically, while holding the outlet 13 of the magazine 11 with a fingertip, the outlet portion is inserted into the mounting hole 3 of the magazine supporting portion 3, and the lower edge of the outlet 13 is engaged with the step portion 3b. As a result, the magazine 11 is supported at the same angle as the mounting hole 3, that is, in a state of being inclined by about 60 ° with respect to the perpendicular. At the same time as mounting, as shown in FIG. 1, the lowest article P in the magazine 11 flows down and contacts the vertical wall 3c, where its position and orientation are corrected and dropped onto the guide groove 2. In the illustrated example, the lower two articles P in the magazine 11 sequentially flow down and are vertically stacked on the guide groove 2, and the third and subsequent articles P are restricted from falling by the upper article P.

When the mounting of the magazine 11 is completed, a power switch (not shown) is turned on. In the state of FIG. 1 in which the article P is not above the optical sensor 4, external light is incident on the optical sensor 4 and operates, whereby the motor 25 of the pushing mechanism 21 operates and the cam 24 moves in a predetermined direction. Rotate 360 °. The rotation of the cam 24 is controlled by, for example, detecting a detection piece provided on the cam 24 with a limit switch. By the rotation of the cam 24, the rotational movement is converted into a linear movement by the drive arm 23, and the pushing arm 22 advances in the guide groove 2.

When the lower article P stacked on the guide groove 2 is extruded slightly forward by the forward movement of the extrusion arm 22, the upper article P is extruded by the extrusion arm 22 as shown in FIG. Then, the article P in the magazine 11 is slightly lowered by entering the recess 22a.

When the recess 2a of the extrusion arm 22 passes through the vertical wall 3c, the lowest article P in the magazine 11 flows down, as shown in FIG. 6, and abuts on the vertical wall 3c to remain. The stacked articles P are stacked on each other and one article P in the magazine 11 is lowered. The extruded article P moves to the front end portion of the guide groove 2 when the cam 24 rotates by 180 °, and the entry of external light to the optical sensor 4 is blocked by the article P.

When the cam 24 further rotates from the state shown in FIG. 6, the extrusion arm 22 retracts in the guide groove 2 contrary to the above. In the process in which the recess 22a passes through the vertical wall 3c when the extrusion arm 22 retracts, the lower articles P stacked as shown in FIG. 7 enter the recess 22a of the extrusion arm 22 twice and move up and down. Both articles P swing back and forth. When the cam 24 has rotated 180 ° from the state shown in FIG. 6, the pushing arm 22 returns to the same position as in FIG. 1, where the operation of the motor 25 is stopped and one pushing operation is completed. ..

When the article P at the front end position of the guide groove 2 is taken out by the suction pad or the like, the motor 25 of the pushing mechanism 21 is actuated by the incidence of external light on the optical sensor 4 and the cam 24 is moved. It is rotated by 360 degrees again, and the next article P is extruded to the same position. That is, each time the article P at the front end position of the guide groove 2 is taken out, the pushing mechanism 21 operates and the articles P are sequentially pushed out.

By the way, when the external light is incident on the optical sensor 4 due to a defective extraction or the like while the article P still remains at the front end position of the guide groove 2, the push-out mechanism 21 operates in the same manner as described above. It may happen. However, in the above-mentioned push-out mechanism 21, the forward movement of the push-out arm 22 is obstructed by the article P in the guide groove 2, and when the push-out arm 22 receives a resistance exceeding the attracting and holding force of the magnet 23b, FIG. And as shown in FIG. 9, the holding of the operating pin 22b by the magnet 23b is released, and the operating pin 22b slides along the elongated hole 23a, so that the pushing arm 22 is moved relative to the driving arm 23. Retreat to. That is, even if the pushing mechanism 21 is accidentally operated in a state where the article P remains at the front end position of the guide groove 2, an extra pushing load is not applied to the article P in the guide groove 2.

As described above, in the above-described article supply apparatus, since the magazine 11 in which the articles P are stored is attached to the apparatus main body 1 in a state of being inclined by about 60 ° with respect to the vertical line, the conventional article of the upper article The entire weight is not applied to the extruded article, and the load applied to the extruded article P is reduced as much as possible to prevent the article from being caught with the upper article, and the article P can be extruded smoothly without resistance. . Further, because of the reduction of the extrusion resistance, a small output motor 25 can be used as a driving source, and the running cost can be reduced and the apparatus itself can be made compact.

Further, since the article P flowing out from the magazine 11 is brought into contact with the vertical wall 3c and the position and the direction thereof are corrected here and then dropped into the guide groove 2, the article P flows down from the inclined magazine 11. Also, the extruded article P can be smoothly extruded in an appropriate state without the article P tilting or falling on the guide groove 2.

The pushing mechanism shown in the above embodiment may be replaced with another mechanism having the same function, for example, a pushing mechanism as shown in FIG. The pushing mechanism 31 shown in FIG. 11 comprises a pushing arm 32, a first arm 33, a second arm 34, a cam 35, and a motor 36. The push-out arm 32 has a vertically long flat plate shape, has a recess 32a on the upper surface of the front end, and an engaging piece 32b on the upper surface of the rear end, and slides in the guide groove 2 of the main body 1 of the apparatus. Arranged freely. The first arm 33 has a vertically long flat plate shape, the upper end of which is swingably engaged with the engaging piece 32b, and the lower end of which is the second arm via a flexible hinge member 33a. It is swingably supported on the rear surface of the upper end of the frame 34. A first magnet 33b is attached to the first arm 33 at a position near the hinge member. The second arm 34 has a vertically long flat plate shape, and its substantially central portion is axially supported by the side surface of the apparatus main body 1 via a shaft member 34a. A second magnet 34b having a polarity different from that of the first magnet 33b is attached to a portion of the second arm 34 facing the first magnet 33b, and a lower end portion of the second arm 34 is attached to the lower end portion. The third magnet 34c is attached. The cam 35 is formed by attaching an eccentric shaft 35a to a disk made of a ferromagnetic metal, and the lower end of the second arm 34 is in contact with the peripheral surface thereof by the magnetic force of the third magnet 34c. Further, a spur gear 35b is attached to the eccentric shaft 35a of the cam 35. A reduction gear 36a is attached to the motor 36, and a crown gear 36b is attached to the output shaft of the reduction gear 36a. The crown gear 36b meshes with the spur gear 35b.

In the push-out mechanism 31, the second arm 34 and the first and second magnets 33b, 34b are attracted to each other by rotating the cam 35 in a predetermined direction by the motor 36. The pushing arm 32 can be moved forward or backward in the inner groove 2 by swinging the first arm 33 held on the arm 34 side back and forth. Further, when a resistance exceeding the attraction and holding force of the first and second magnets 33b and 34b acts on the pushing arm 32 when the pushing arm 32 moves forward, the first arm 33 uses the hinge portion as a fulcrum. By swinging, the pushing arm 32 can be retracted relative to the second arm 34. The main extrusion mechanism 31 can also obtain the same operation and effect as the above-mentioned embodiment.

The rotation control of the cam of the push-out mechanism is not limited to that shown in the embodiment, but a control circuit capable of controlling the rotation angle of the motor by the number of pulses, and a timer when the motor is rotated by a timer. It may be a control circuit or the like capable of controlling the distance.
