Connected to. Then, the upper end of the feed tube is used as the entrance of the chip component, and the feed tube is continuously arranged from the vertical direction to the horizontal direction, and only the entrance is open to suck air. Thus, the chip component can be fed in a configuration in which the feeding tube has a horizontal portion, and the device is capable of feeding the chip component at high speed and reliably by forcibly feeding without relying on gravity. Further, the same applies to a case where a square groove passage is provided instead of the feeding tube as an application suitable for the square chip component, and the component stopper member is fixed to the device at the tip of the square groove passage. Therefore, the pushing force of the tip component following the tip component does not act on the opening except at the time of suction, and the tip component can be made free without any special separating means. However, in order to be completely free, it is desirable that the subsequent chip component is slightly retracted at one end, but it is difficult for the subsequent chip component to retreat as desired because a plurality of continuous chip components are continuous. It is an object of the present invention to provide a chip component supply device in which a side is slightly retracted to loosen a leading-edge chip component and put in a free state in which a suction pin of a mounting head can be reliably picked up.

In order to achieve the above-mentioned object, a chip component supply device according to the present invention is provided, wherein one end of a tubular supply path for chip components is used as an entrance for chip components, an opening for removing components and air suction. A component stopper having a hole is connected to the other end side of the tubular feeding path, a shutter for opening and closing the component removal opening is provided, and the opening is closed by the shutter so that the entrance is open. In the chip component supply device for feeding the chip components in the tubular feeding path by air suction, a stopper is provided in the component stopper portion where the tip of the chip component fed by air suction abuts, and the shutter is provided with the shutter. When opening the opening, the stopper is configured to move by a predetermined distance in a direction away from the tip of the chip component, and feeds the chip component on a guide. A slide groove is provided at the guide end in the direction, and the stopper and the shutter are slidably guided in a direction along the groove in the slide groove, and the stopper contacts the tip of a chip component fed by air suction. The shutter is biased toward a position positioned in the opening, and the movement of opening the opening of the shutter pushes the stopper and separates the shutter from the position by a predetermined distance against the bias.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a chip component supply device according to the present invention will be described with reference to the drawings. Details of this embodiment will be described with a configuration suitable for square chip components, but the basic configuration is as follows. Generally used for chip parts.

FIG. 1 shows the overall configuration of the present invention. In this figure, what is indicated by a virtual line 1 is a supply base of the chip component mounting machine, and the main body frame 10 of the chip component supply device is mounted on the supply base 1. An auxiliary frame 10A is fixedly integrated with the main body frame 10.

At the right end of the auxiliary frame 10A, a slide guide 11 is erected and fixed. A middle pipe type hopper is mounted on a slider (also used as a hopper mount) 12 which is slidably supported by the slide guide 11 in a vertical direction. 13 is mounted. A large number of loose chip parts 15 are accommodated in the middle tube type hopper 13, and a supply port 16 is opened on the right side of the hopper 13. The supply case proposed by the present applicant in Japanese Patent Application No. 7-95842. The chip component 15 is supplied from the supply case 91 into the hopper 13 through the supply port 16 by mounting the holder 91 on the holder 90. The holder 90 includes the hopper 13 and mounts the supply case 91. A motor mounting plate 18 is fixed to the lower right side of the auxiliary frame 10A, and a DC motor 19 for elevating and lowering the hopper is fixed to the mounting plate 18. The motor 19 has a speed reducer 19A, and a cam (or crank) 20 is fixed to a rotation shaft thereof. The cam 20 is connected via a cam follower (or link) 21 to the slider 1 serving also as a hopper mount.
2 Accordingly, the rotation of the motor 19 causes the slider 12 and the hopper 13 to reciprocate up and down. However, FIG. 1 shows the lowered position of the hopper 13.

At the upper left of the auxiliary frame 10A, a part guide 22 is erected and fixed, and the part guide 22 holds a connecting member 26 connected to the upper end of a square groove passage 25A constituting the tubular feeding path 25. The connecting groove 26 has a square groove passage 2.
A separation pipe 27 communicating with 5A is connected and fixed. The separation pipe 27 is inserted into a lower supply hole of the hopper 13.

As shown in FIGS. 2 to 5, a component stopper 3 is connected to the left end of the tubular feeding path 25.
FIG. 2 is a cross-sectional view showing a main configuration of the component stopper 3, and FIG. 3 is a view of the component stopper 3 as viewed from above. FIG. 4 shows a state in which the guide cover 32 and the shutter 53 are removed from FIG. 3 and the position of the concave portion 52 of the shutter retainer 51 is viewed in cross section. The component stopper member 30 is a guide 3 fixed to the upper end of the main body frame 10.
1 is disposed on the left end. The guide 31 is continuously connected to the tubular feed passage 2 from the square groove passage 25A of the part guide 22 on the upper side.
The guide cover 32 is fixed with easily removable small screws 35 so as to cover the upper surface thereof and prevent the chip component 15 from protruding from the square groove passage 25B.
As shown in FIG. 1, a component detection sensor 36 is disposed at an intermediate portion of a square groove passage 25A connecting the vertical portion and the horizontal portion of the tubular feeding path 25. That is, the square groove passage 2

Are attached to the parts guide 22. Note that a transparent pressing plate 37 that covers the square groove passage 25A from the side surface is fixed to the part guide 22 so that the chip component 15 does not jump out including the detection position of the component detection sensor 36. When the component detection sensor 36 detects the presence of the chip component 15, the DC
The power of the motor 19 is turned off, the movement of the hopper 13 is stopped, and the supply of the chip component 15 is stopped. Although the component detection sensor 36 is turned on and off momentarily when the component passes, the motor 19 has inertia and does not actually stop. When the chip components 15 continue in a line from the component stopper portion 3 and the terminal ends to block the light of the component detection sensor 36, the operation stops. As a result, a predetermined amount of the chip component 1 is always added to the horizontal portion and a part of the arc-shaped portion of the tubular feeding path 25.
5 exists.

As shown in FIGS. 2 to 5, a component stopper member 30 located at the tip of the tubular feeding path 25 and a square groove passage 25 continuous with the square groove passage 25B provided in the guide 31.
C and a block guide 40 fixed to the guide 31
A shutter 53 and a shutter presser 51; a component take-out position 41 that is opened when taking out a component; an air suction hole 42 provided in the projection 30A of the component stopper member 30 and communicating with the component take-out position 41; The air suction hole 43 provided in the shutter 53 and the component stopper 3 for taking out the component are formed. Here, the component take-out position 41 is in a state where the shutter 53 is closed as shown in FIG.
The stopper surface 3 in which the most advanced chip component 15 sucked by the air suction of the air suction hole 42 abuts on the protrusion 30A of
0C. The end of the chip component 15 at the forefront in the tubular feeding path 25 abuts against the stopper surface 30C, and is positioned at the component take-out position 41.

The air suction hole 43 is bent at a right angle in the shutter 53 and has an outlet on the side surface. As shown in FIGS. 2 and 5, when the shutter 53 closes the component take-out position 41, the guide 31 is closed. Side air suction hole 44 (second
In the figure, the one end of the air suction hole 44 coincides with one end of the air suction hole 43 as shown in FIG.
When the shutter 53 is opened, the mutual positions are shifted and no longer coincide with each other, and the shutter 53 is opened and closed to communicate with the main body frame 10 via a space 45 (indicated by a virtual line in FIG. 2). Connected to a negative pressure source such as a vacuum pump via a hose 47 from
1 is a vacuum generator 48 that generates a negative pressure when supplying pressure air, a pressure air supply hose 49 to the vacuum generator 48, and a pressure (not shown) for supplying pressure air to the hose 49. It is composed of a pneumatic circuit including an air source and a solenoid valve for intermittent supply. A slide groove 50 is provided at the left end of the guide 31 at a position near the left end of the main body frame 10, and the component stopper member 30 and the shutter 53 overlap with the slide groove 50 and are slidably guided in a direction along the groove. The shutter holder 51 is fixed to the guide 31 so as to slidably hold and guide the shutter 53 from above. Inside the shutter retainer 51, a concave portion 52 is provided at a position corresponding to the protrusion 30B of the component stopper member 30, and a concave portion 30E is also provided at a position opposite to the protrusion 30B. Concave hole 5
The return spring 55 of the component stopper member 30 which works so as to push and spread with respect to 2, 30E is arranged. Therefore,
The part stopper member 30 for the shutter holder 51
The stopper surface 30C abuts on the distal end surface of the block guide 40 by being pushed by the return spring 55. In this state, the surface of the shutter retainer 51 where the concave hole 52 is provided and the protrusion 30B of the component stopper member 30 A predetermined gap G is formed between the chip surface 15 and the opposing surface. In this state, the leading-edge chip component 15 sucked by the air suction of the air suction hole 42 comes into contact with the stopper surface 30C and is positioned at the component take-out position 41. It is supposed to be.

The shutter 53 has a protruding portion 53A protruding from a surface pressed by the shutter presser 51 on one side, and a concave groove portion 54 is provided on a side surface portion of the shutter 53 including the protruding portion 53A. On the other hand, on a side surface of the main body frame 10, a plate-shaped drive lever 57 and an intermediate lever 60 are pivotally mounted on a fulcrum shaft 59 (not visible inside the screw in FIG. 1, but the axis is concentric with the screw). The supporting disk 58 is screwed and fixed to the end face of the fulcrum shaft 59 so that the driving lever 57 and the intermediate lever 60 do not fall off and do not swing in the thickness direction. To be pivoted freely. At the upper part of the drive lever 57, an engaging pin 56 is fixed at right angles to the plate surface, and the engaging pin 56 is engaged with a concave groove 54 provided in the shutter 53. Shutter 5 via engagement pin 56
3 can be slid in the direction along the slide groove 50. The drive lever 57 has an arm portion 57A on the left end and an engagement protrusion 57B on the lower side. Intermediate lever 6
0 is inside the drive lever 57 (the body frame 10
Side), the intermediate lever 60 has an arm portion 60A on the left end and an arm portion 60B on the lower side.
A and the arm portion 57A of the drive lever 57 are vertically opposed on the left side, and a tension spring 62 is stretched in a spring hook hole provided at each end of the arm portion, so that the arm portion 60A is always provided.
And the arm portion 57A are brought closer to each other. Then, the stopper pin 6 is perpendicular to the plate surface of the intermediate lever 60.
1 and the stopper pin 61 is attached to the drive lever 57.
Since it comes into contact with the lower engaging projection 57B, the arm 60
A and the arm portion 57A are prevented from approaching by the tension spring 62 at a predetermined interval. Therefore, when the intermediate lever 60 is normally swung, the drive lever 57 is also swung integrally, that is, the intermediate lever 60 is moved rightward. When the stopper lever 61 is turned, the force is transmitted in the direction in which the stopper pin 61 pushes the engagement protrusion 57B, and when the intermediate lever 60 is turned in the counterclockwise direction, the tension spring 62 transmits the force in the direction in which the arm portion 57A is pulled. When a drag force greater than the force transmitted by the extension spring 62 acts, the extension spring 62 expands and the drive lever 57 does not follow the movement of the intermediate lever 60.

A support plate 67 is provided at an intermediate position of the main body frame 10.
A fulcrum shaft 68 is fixedly screwed on the upper portion of the support plate 67 (in FIG. 1, the shaft portion on the side where the fulcrum shaft 68 fits into a hole formed in the support plate 67 is shown). (The flange portion and the fulcrum shaft portion which are visible and screwed are not visible on the other side.) The drive plate 66 is pivotally supported by the fulcrum shaft 68 in parallel with the plate surface of the support plate 67 and is not shown. A retaining shaft is provided on the fulcrum shaft 68 from the other side. Drive plate 66
Has an inverted L-shape, and a block 69 (on the back side in FIG. 1 and shown by a dotted line) is screw-fixed to a portion extending upward to the left end, and a support shaft 65 fixed to a portion extending downward.
The other end of the connecting lever 63 is pivotally supported by a support shaft 64 fixed to the lower arm portion 60B of the intermediate lever 60, and when the driving plate 66 is swung, the intermediate lever is pivoted. 60 constitutes a link mechanism that swings.
The connection lever 63 is rotatable with respect to the support shafts 64 and 65 and is prevented from falling off. A spring hook 71 is attached to a side surface of the main body frame 10, and another spring hook 72 is attached to a lower end of a portion where the driving plate 66 extends downward, and a tension spring 70 is stretched over each spring hook 71, 72. Do
The extension spring 70 always works to turn the drive plate 66 clockwise, and when it works to turn the intermediate lever 60 clockwise through the connecting lever 63, it works to turn the drive lever 57 clockwise through the stopper pin 61. Then, the shutter 53 is moved rightward from the engaging pin 56 via the concave groove 54 so that the right end of the shutter 53 comes into contact with the left end of the guide cover 32 and stops. The position 41 is constantly urged in the closing direction, and the portion where the block 69 is fixed to the portion extending to the left end above the driving plate 66 is always lifted.
Therefore, when the push-down lever of the drive means provided in the chip component mounting machine presses the block 69 in the direction of arrow F,
The drive plate 66 swings counterclockwise against the tension spring 70, and thus swings the intermediate lever 60 counterclockwise via the connecting lever 63. The counterclockwise swing of the intermediate lever 60 is a tension spring. An engagement pin 56 fixed to the drive lever 57 swings the drive lever 57 counterclockwise through 62 and moves the shutter 53 to the left.
The shutter 53 pushes the component stopper member 30 and moves to the left together, and the shutter 53 pushes the component stopper member 30 and moves leftward against the return spring 55 to eliminate the gap G, and the projection portion of the component stopper member 30. The movement stops when 30B hits the shutter retainer 51. Even if the shutter 53 cannot move in the left direction, if the position of the block 69 is still pushed down in the direction of arrow F, the intermediate lever 60 swings counterclockwise but the drive lever 57 cannot move the shutter 53, so the engagement pin 56 And the extension spring 62 is extended. Separately from the above configuration, the fulcrum pin 7 fixed to the lower side
4, a driving member 73 pivotally supported is provided. The driving member 73 has an elongated hole 75 in a left arm portion thereof, and a roller 76 is rotatable on an arm portion 60B below the intermediate lever 60. The other arm that is pivotally attached, and thus protrudes downward from the driving member 73, is moved to the position of the arm in the direction of arrow F 'by the engaging lever of the driving means provided in the chip component mounting machine. When you press
The intermediate lever 60 swings counterclockwise via the roller 76, that is, the shutter 53 can be moved from below.

A set piece 80 is attached to the left end of the main body frame 10 and a lock claw 81 is attached to the lower side.
The set piece 80 engages with the front wall of the supply base 1 on the chip component mounting machine side. The lock claw 81 is a link plate 82
, The lock lever 83 and the fulcrum plate 84 constitute a toggle mechanism. The lock claw 81 comes off the supply portion base 1 when the lock lever 83 screwed and fixed to the fulcrum plate 84 pivotally attached to the main body frame 10 is pulled up as shown by the imaginary line 83 'in FIG. In this state, the main body frame 10 and all the mechanisms attached thereto can be removed from the base 1. When the lock lever 83 is in the state shown by the solid line, it is in the mounted state, and the lock claw 81 is engaged with the engaging plate 85 on the chip component mounting machine side.

Next, the operation of the overall configuration in the above embodiment will be described. First, supply case 9 is attached to holder 90.
1 and open the exit shutter of the supply case 91, and insert the chip component 1 into the hopper 13 from the supply case 91.
5 is supplied from the supply port 16, the supply case 91 is mounted on the holder 90 as it is,
The chip components 15 are naturally replenished so as to have a substantially constant amount based on the upper side of the replenishing port 16. Thus, the rotation of the motor 19 causes the middle tube type hopper 13 to perform reciprocating up and down movements via a cam (or crank) mechanism. For this reason,
Bulk (loose) chip parts 15 in the hopper are passed from the lower part of the hopper through the separation pipe 27 to the tubular feeding path 2.
5 falls down the vertical portion of the square groove passage 25A, and eventually reaches the right end of the horizontal portion of the tubular feeding passage 25. In the horizontal part, the chip component feeding action by gravity is eliminated. For this reason, as shown in FIGS. 2 and 3, the component take-out position 41 of the component stopper portion 3 is sealed with a shutter 53,
Only the upper end of the separation pipe 27 is opened, and air is sucked from the air suction holes 42 and 43 via the hose 47. As a result, an air flow is generated through the external ventilation hole of the hopper 13, the inside of the hopper 13, the separation pipe 27, the tubular feed passage 25, and the hose 47 through the air suction hole 42, and the air flows in the horizontal portion of the tubular feed passage. The chip component 15 receives the feeding force in the left direction, and the tip component 15 at the forefront comes into contact with the stopper surface 30C in the square groove passage 25C of the block guide 40 and stops. That is, the most advanced chip component 15
Is positioned and stopped in the square groove passage 25C at the component take-out position 41.

Thereafter, when a driving means provided in the chip component mounting machine, for example, a push-down lever provided in a mounting head for picking up the chip component 15 at the component pick-up position 41 pushes the block 69 in the direction of arrow F, the driving plate 66
Swings counterclockwise against the tension spring 70, swings the intermediate lever 60 counterclockwise via the connecting lever 63, and swings the drive lever 57 counterclockwise via the extension spring 62, and so on. Then, the shutter 53 is moved to the left via the engagement pin 56. Since the position of the block 69 is not normally pushed in the direction of the arrow F, the pulling force of the tension spring 70 is applied to the shutter 53 from the stopper pin 61 by the engaging projection 5.
Acting through 7B, it comes into contact with the left end of the guide cover 32 to seal the component take-out position 41. When the drive plate 66 starts to swing counterclockwise when the push-down lever is pressed, the shutter 53 is moved to the left, so that the shutter 53 does not come into contact with the left end of the guide cover 32. The driving lever 57 transmits the counterclockwise force to the driving lever 57 while maintaining the state of contact with 57B. The driving lever 57 moves the shutter 53 to the left via the engaging pin 56 to open the component take-out position 41. At the same time, the communication between the outlet from the side of the shutter 53 in which the air suction hole 43 in the shutter 53 is bent at a right angle and the air suction hole 44 on the guide 31 side corresponding to the outlet is performed by the shutter 53.
Is moved to the left so that both holes are out of alignment and cut off, and the air suction holes 42 for the tubular feed passage 25 are
Then, the air suction through the air suction hole 43 is stopped. Further, when the shutter 53 is opened, the component take-out position 41 is set.
Is sufficiently opened, the communication between the air suction holes 43 and the air suction holes 44 is completely cut off, and the state where air suction does not work on the chip component 15 continues.

On the other hand, when the shutter 53 seals the component take-out position 41, the component stopper member 30 located at the tip of the tubular feed path 25 in the component stopper portion 3 as shown in FIGS. The component stopper member 30 is constantly pressed by the return spring 55, and the stopper surface 30C of the component stopper member 30 is in contact with the distal end surface of the block guide 40. As shown in FIG.
The stopper surface 30C blocks the square groove passage 25C of the block guide 40, and the end of the leading-edge chip component 15 sucked in air in the tubular feeding passage 25 abuts and is positioned at the component take-out position 41. The shutter 53
Is moved to the left to open the component take-out position 41,
When the air suction of the air suction hole 42 stops, the lateral feeding force does not act on each chip component, and the chip components are loosened from each other. Further, when the shutter 53 is moved leftward, the left end of the shutter 53 is eventually formed. Is the component stopper member 30
Abuts on the projection 30B of the
Pushes the component stopper member 30 and moves in the left direction together to eliminate the gap G against the return spring 55, and the protrusion 30 </ b> B of the component stopper member 30 abuts against the shutter holder 51 to stop the movement. That is, the component stopper member 3
The zero stopper surface 30C moves in a direction away from the position in contact with the distal end surface of the block guide 40 by the distance of the gap G. In other words, the end of the foremost chip component 15 at the component removal position 41 abuts. Stopper surface 3
0C has escaped by the distance of the gap G, and the suction pin of the mounting head descends to the component take-out position 41 where the shutter 53 is fully opened, and the leading-edge chip component 15
Even if the air suction stops, a number of chip components following the leading-edge chip component 15 cannot be retracted, and even if they are not sufficiently loosened from each other, the leading-edge chip component 15 is not removed. Can be completely free, and there is no failure in removing the chip component 15 by the suction pin.

When the leading-edge chip component 15 is picked up, the drive means pressing the block 69 in the direction of arrow F returns, the shutter 53 returns by the force of the tension spring 70, and the component stopper by the force of the return spring 55. The member 30 returns, and the shutter 53 comes into contact with the left end of the guide cover 32, and the air suction holes 42, 43, and 44 are again formed.
Communicate with each other to feed the next chip component 15 and position it at the component take-out position 41.

It is to be noted that a predetermined amount of the chip component 1 is always stored in the tubular feeding path 25 in order to prevent the state in which the tubular component 15 becomes full or short.
5 is present, the component detection sensor 36 disposed in the middle portion of the square groove passage 25A detects the presence or absence of the chip component 15, and when the presence of the chip component 15 is detected, the motor 19
Is stopped, the hopper 13 is stopped, and the separation pipe 27 is stopped.
The supply of the chip component 15 to the square groove passage 25A is stopped. When the presence of the chip component 15 is not detected, the motor 19 is operated. Therefore, control is always performed so that the chip component 15 is present in the tubular feed path 25 by a predetermined amount.

Further, a portion of the horizontal portion of the tubular feeding passage 25 covered by the guide cover 32, for example, a portion of the square groove passage 25B protruding upward so that the sectional shape of the portion becomes convex. The guide cover 32 is provided as a groove 32A. The chip component 15 is fed in the lower part of the convex shape through the square groove passage 25B, and the groove 32A has a narrow cross-sectional shape in which the chip component 15 does not enter. The role of the groove 32A is to enrich the air flow in the tubular feed passage 25 in air suction,
It functions to make the supply of the chip component 15 smoother, but if the air flow is too abundant, the air suction is wasted, so that the size of the cross section of the groove 32A is naturally limited. In this case, an air hole to the outside is provided at a position where the horizontal portion starts in the middle of the tubular feed passage 25, and only the air flow in the horizontal portion is abundant, rather than a configuration in which only the upper end of the separation pipe 27 is open. In some cases, the chip component 15 can be more smoothly fed.

[0021]

As described above, according to the chip component supply device of the present invention, one end of the tubular supply path of the chip component is used as the entrance of the chip component, and the opening at the component removal position and the air suction hole are provided. A part stopper part is connected to the other end side of the tubular feeding path, a shutter is provided for opening and closing the opening at the part take-out position, and the opening is closed by the shutter so that only the entrance is open. In the configuration in which the chip components in the tubular feeding path are fed by air suction, the component stopper portion has a stopper surface with which the most advanced chip component fed in the tubular feeding path by air suction abuts. A component stopper member is slidably provided, and is pressed by a return spring to bring the stopper surface into contact with the tip of the tubular feeding path, thereby positioning the most advanced chip component at the component removal position. And the communication between the outlet of the air suction hole provided in the shutter communicating with the air suction hole provided in the component stopper member and the inlet of the air suction hole provided in the guide connected to the external negative pressure source. The opening and closing of the two holes does not coincide with each other due to the movement of the shutter, and the component stopper member is moved against the return spring by the opening operation of the shutter, so that the component is removed by the movement of the shutter. It can open and close the position, turn on and off the air suction, and release the stopper surface against which the chip components come in contact.The simple operation ensures reliable operation timing, enabling high-speed operation and simplification.
Space saving and cost reduction can be achieved. In addition, the release operation of the stopper surface is performed together with the opening of the component take-out position, so that the leading-edge chip component is completely free without the subsequent chip component pressing, and the leading-edge chip component is securely held by the suction pin of the mounting head. It is possible to provide an extremely reliable chip component supply device that can be picked up.
