[0018]

In the chip component supply device of the present invention and a hopper used in the device, the hopper is constituted by a supply case for accommodating the chip component, and a hopper base that moves up and down by mounting the supply case. By providing the hopper base with a function of smoothly dropping chip components onto the component separating member, the supply case portion for accommodating a large number of bulk chip components can have a simple and inexpensive structure. Therefore, the supply case can be used as it is as a container for accommodating and storing bulk chip components for distribution. Also, by moving the hopper base up and down with the supply case up and down, the component separation member enters and exits the hopper base,
When the component separating member enters, the chip components in the hopper base and the supply case are slightly raised, so that a bridge (chip components become bridged and become clogged) in the hopper base and the supply case. Has been prevented. The chip component is separated by dropping the chip component from the hopper base into a through hole or groove having a cross-sectional shape through which one chip component of the component separating member can pass with the vertical movement of the hopper base. Chip components can be incorporated into holes or grooves in the separating member. Note that the chip components fall in a row in the holes or grooves of the component separating member as the hopper base moves up and down.

The hopper base has a funnel-shaped space that opens upward and gradually narrows downward, and a hole that communicates with the lowermost portion of the funnel-shaped space and that penetrates the component separating member. In this case, the dropping of the chip component onto the component separating member can be performed more smoothly, and the occurrence of clogging can be prevented.

The supply case may be separate from the hopper base so as to be detachable, has at least a space for accommodating chip components, and has a lower opening corresponding to the opening above the funnel-shaped space. It can be simply provided, has a simple structure, and can be inexpensively distributed as a container for storing and storing chip components.

Further, in the chip component supply device of the present invention, a component pick-up opening corresponding to a component pick-up position is provided at a tip end side of an alignment chute having a component supply path connected to a hole or a groove of the component separating member. Provided, further provided with a shutter for opening and closing this and an air suction path communicating with the component feeding path, with the shutter closed
Is connected to the air suction path and the parts feeding path.
The air is sucked in the part feeding path, and the shutter is opened.
The air suction path is
Since a structure of blocking, reliably feed the parts feed passage in the closed state of the shutter without resorting to gravity chip components ranging from the entrance of the component feed path by air suction to part take-out opening it can. In addition, since the transfer of the chip components is performed by air suction, the generation of dirt in the component supply path is small, and the scattering of dirt, dust, and the like to the outside of the device is small, so that it is possible to cope with a clean room.

Further, the supply case comprises: a case body;
In the case where the case component has an outer lid that is openably and closably or detachably attached to the entrance of the chip component on the upper part of the case body and a case shutter that opens and closes the lower opening, the outer lid is removed during the operation of the chip component supply device to remove the chip component. The supply of chip components to the hopper base can be appropriately stopped by closing the case shutter.

Further, when the supply case has an inner lid which is provided in the accommodation space so as to be able to descend by its own weight and presses the accommodated chip parts from above, the chip part accommodated by the inner lid is pressed by its own weight. For example, in the case of a configuration in which the chip component supply device moves and delivers the chip component to the mounting head of the chip component mounting machine, the chip component swings in the case body due to the movement, and the chip component is broken or chipped. Can be prevented or a situation in which the toner is charged and adheres to the inside of the case body can be prevented.

Further, the case shutter of the supply case has a through hole having a shape substantially continuous with an upper opening of the funnel-shaped space of the hopper base in the opened state, and the lower opening of the case main body also has the same shape. When the shape is substantially continuous with the opening at the upper part of the funnel-shaped space, the edges of the case shutter and the opening of the case main body protrude like an eave above the funnel-shaped space, and the chip component falls smoothly. Can be avoided.

Further, when the funnel-shaped space of the hopper base is formed inside the lower funnel-shaped surface having a gentle slope and the upper funnel-shaped surface following the steep slope, the width of the hopper base is reduced. Even if it is narrow, it is possible to prevent clogging such as bridges of chip components in the funnel-shaped space.

When the rotation lever 84 rotates clockwise, the shutter opening / closing arm 81 rotates clockwise by the engagement portion 83 being pushed by the engagement pin 85, and the shutter 73 slides rightward to close.

The other end of the connecting arm 86 is pivotally connected to an operating lever 88. The operation lever 88 is rotatably supported by a support plate 89 fixed to the main body frame 10, and an operation unit 91 provided at an upper portion receives an operation force F on the chip component mounting machine side. It is designed to rotate left. The operation force F is interlocked with the lowering of the suction pin 2 when the suction pin (component pickup pin) 2 on the chip component mounting machine side shown in FIG. To be added. A tension spring 92 is provided between the lower end of the operation lever 88 and the main body frame 10. When the suction pin 2 returns to the raised position and the operation force F to the operation section 91 is released, the operation lever is released. 88 is urged to rotate clockwise. When the operating lever 88 receives the operating force F of the driving source, the operating lever 88 rotates left and the connecting arm 8
6 is pulled to rotate the rotation lever 84 counterclockwise. When the operation force F of the drive source to the operation lever 88 is released,
The operation lever 88 is rotated clockwise by the tension spring 92, and pushes the connecting arm 86 to rotate the rotation lever 84 clockwise.

As described above, the opening and closing of the shutter 73 is as follows.
The shutter opening / closing arm 81, the rotating lever 84, the connecting arm 86, and the operation lever 88 are operated in conjunction with each other. At this time, the shutter opening / closing arm 81 and the rotation lever 84 are connected by a tension spring 87, and the left rotation of the shutter opening / closing arm 81 is made to follow the left rotation of the rotation lever 84. In the case where a force that obstructs the left rotation of the shutter opening / closing arm 81, that is, a force greater than the tension force of the tension spring 87 is applied, the tension spring 87 expands and absorbs this force. Shutter opening / closing arm 8
1 does not forcibly follow the left rotation of the rotation lever 84. The right and left rotation of the shutter opening / closing arm 81 and the rotation lever 84 is connected by utilizing the pulling force of a tension spring 92 provided between the operation lever 88 and the main body frame 10 (biasing the operation lever 88 in the right rotation direction). Since the operation is performed through the arm 86, the shutter 73
During the closing operation (sliding to the right), some trouble occurs, and the shutter opening / closing arm 81 and the rotating lever 8
When a force that prevents the right rotation of the shutter 4 is applied, that is, a force greater than the pulling force of the tension spring 92, the rotation of the operation lever 88 is stopped, and the shutter opening / closing arm 81 and the rotation lever 84
Is not forced to rotate to the right. Therefore, when opening or closing the shutter 73, even if the chip component 20 is caught in the component take-out opening 100 which is a gap between the shutter 73 and the tip side chute lid 68, etc. No action is taken.

As shown in FIG.
An optical sensor 95 as a component detection sensor is arranged on the left side of the middle part of the image forming apparatus. The optical sensor 95 has a light emitting element and a light receiving element (not shown) opposed to each other across the component feeding path 62 of the linear chute 61, and both of them are attached to the main body frame 10 side. A small transmission hole 96 is formed in the chute lid 64 and the linear base 63 so that a light beam from the light emitting element is transmitted to the light receiving element, and an optical path between the light emitting element and the light receiving element (dashed line S). ) Passes through the linear component feed path 62.
As shown in FIG. 14, the optical path is interrupted by the presence of the chip component 20 on the optical path of the optical sensor 95 in the component feeding path 62,
The presence of the chip component 20 is detected.
When the optical sensor 95 detects the presence of the chip component 20, the DC motor 42 is turned off, the movement of the hopper 13 is stopped, and the supply of the chip component 20 is stopped. When the parts pass, the sensor 95 is turned on and off instantaneously, but the motor 42 has inertia and does not actually stop. As shown in FIG.
The DC motor 42 stops when 0 is connected to the component stopper 71 in one line and the aligned end continuously blocks the light of the optical sensor 95. This ensures that an appropriate number of chip components 20 are present in the component feed path 62.

Here, the transmission type optical sensor in which the light emitting element and the light receiving element are arranged opposite to each other is used, but a reflection type optical sensor in which the light emitting element and the light receiving element are arranged in parallel may be used.

As shown in FIG. 1, the main body frame 10
On the lower side, a feeder lock lever 101 and a lock claw 102 are attached. The feeder lock lever 101 and the lock claw 102 are pivotally attached to the main body frame 10, respectively, and both are connected via a connection link 103. Although not shown, a spring for biasing the feeder lock lever 101 in the locking direction (clockwise direction in FIG. 1) is provided between the feeder lock lever 101 and the main body frame 10. The lock claw 102 is disengaged from the pin 104 provided on the supply unit base 1 of the chip component mounting machine when the feeder lock lever 101 is pulled up as shown by the imaginary line Q in FIG. And it is possible to remove all the mechanisms attached thereto. When the feeder lock lever 101 is in the state of the solid line in the figure, it is in the mounted state,
The locking claw 102 is adapted to engage with the pin 104.

Next, the operation of the overall configuration of the above embodiment will be described.

First, a supply case 14 accommodating a large number of chip components 20 is mounted on a hopper base 15 fixed to the hopper base 12 to constitute a hopper 13.
The case shutter 27 of the supply case 14 is opened so that the chip component 20 in the supply case 14 can drop into the funnel-shaped space 21 of the hopper base 15.

Then, the switch 45 is turned on to set the hopper elevating DC motor 42 in a rotatable state. When the optical sensor 95 does not detect the aligned end of the line of chip components 20 in the linear component feed path 62 of the linear chute 61, the DC motor 42 rotates and the hopper base via the cam mechanism. 12 and the hopper 13 are moved up and down. For this reason, the separation and alignment pipe 55 enters and exits the funnel-shaped space 21 through the hole 22 of the hopper base 15, and the supply case 14 extends from the funnel-shaped space 21.
The chip component 20 reaching inside is raised, lowered and slightly moved. Along with this, the bulk (loose) chip components 20 in the hopper enter (fall) one by one into the through-holes of the separating and aligning pipe 55 that rise and fall with respect to the holes 22 of the hopper base 15. The chip component 20 passes through the through hole of the pipe 55, falls on the vertical portion of the arc-shaped component feeding path 52 formed in the arc-shaped chute 53, is gradually turned sideways, and reaches the left end of the horizontal portion.

In the horizontal portion, the chip component feeding action by gravity is lost. For this reason, as shown in FIG. 11, the component picking-up opening 100 at the component pick-up position P on the tip side of the linear chute 61 is closed by the shutter 73, and only the upper end of the separation and alignment pipe 55 is substantially open. Then, vacuum suction is performed by the vacuum generator 78 through the air suction paths of the air suction holes 74 and 75, the barb joint 76 and the hose 77. As a result, an air flow is generated through a component feed path in which the through-hole of the separation and alignment pipe 55, the arc component feed path 52, the linear component feed path 62, and the linear groove 66 communicate with each other, and the arc component is generated. From the horizontal portion of the feed path 52 to the linear component feed path 62,
The chip component 20 in the straight groove 66 receives the feeding force in the left direction, and the leading-edge chip component 20 comes into contact with the component stopper 71 and stops. That is, the leading-edge chip component 20 is positioned and stopped at the component pickup position P of the component extraction opening 100. Since the component feeding path is substantially airtight, the chip component 20 receives a feeding force by vacuum suction from the through hole even in the arc-shaped component feeding channel 52. Can be dropped.

Thereafter, the suction pin 2 on the chip component mounting machine side shown in FIG. 13 is lowered, and an operating force F is applied to the operating portion 91 of the operating lever 88, so that the connecting arm 86 and the rotating lever 84 are linked to operate the shutter opening / closing arm. Rotate 81 to the left and slide shutter 73 to the left. As a result, first, when the shutter 73 is opened halfway, the external communication hole 79 is opened.
Forms an air passage communicating with the outside, substantially disables the air suction of the air suction hole 74, and furthermore, in a state where the shutter 73 is open, the bottom surface of the shutter 73 closes the upper end opening of the air suction hole 75, The state where the air suction path is cut off and the air suction does not work on the chip component 20 continues. Then, in the fully opened state of the shutter 73 in FIG. 13 (the fully-opened state of the component take-out opening 100), the suction pin 2 on the mounting machine side descends to suck the leading-edge chip component 20 at the component pick-up position P, lift it up and transfer it. I do. During this transfer operation, the air suction holes 7 on the side of the linear base 63
5, the air suction hole 74 communicating with the linear component feed path 62 does not apply a suction force to the chip component 20 in a state where the air suction is stopped. No lateral feeding force acts on the components, and they are in a mutually loose state, and there is no failure in removing the chip component 20 by the suction pin 2.

If there are chip components continuously from the horizontal portion to the vertical portion of the component feeding path 52, a lateral force due to gravity may be applied to the most advanced chip component 20. In addition, even if the suction is stopped, if there is a rear component to which a force due to gravity is applied, the components in one line do not become loose. For this reason, when the optical sensor 95 located at the intermediate portion of the linear chute 61 detects a series of rows (aligned ends) of the chip components 20 at the arrangement position, and detects an aligned series of chip components. DC motor 42
Is stopped, the vertical movement of the hopper 13 is stopped, and the supply of the chip component to the component supply path is stopped.
Therefore, when the chip components are sucked by the suction pins 2, each chip component is located only on the linear chute 61.

When the suction pin 2 sucks the chip component 20 and moves upward, the operating portion 9 of the operating lever 88 is moved.
1 is released, the operating lever 88 is rotated clockwise by the tension spring 92, and the connecting arm 86 and the rotating lever 84 are rotated.
Rotates the shutter opening / closing arm 81 clockwise to slide the shutter 73 rightward. As a result, the shutter 73 is closed, the component take-out opening 100 is closed, the air suction hole 74 communicates with the air suction hole 75 on the side of the linear base 63, and the air suction of the air suction hole 74 becomes effective. Then, the chip component 20 receives a feeding force in the left direction by air suction, and the foremost chip component 20 comes into contact with the component stopper 71 to be positioned and stopped at the component pick-up position P of the component take-out opening 100, and the suction pin 2 is stopped. Standby state for component removal.

According to the above embodiment, the following effects can be obtained.

(1) The hopper 13 is connected to the hopper base 1
A hopper base 15 fixed to the second horizontal portion 12b, and a supply case 14 which can be detachably mounted vertically to the hopper base 15, and the supply case 14 has a simple and inexpensive structure. It can be used as it is as a container for accommodating and storing the bulk chip component 20.

The supply case 14 has a structure in which chip components are inserted through an entrance 25a above the case main body 25 and taken out through a lower opening 25c at the center of the lower part of the case main body.
5a can be set to an optimal opening size for packing of chip components, and the lower opening 25c can be set to an optimal shape and size for dropping chip components to the hopper base 15. The supply case 14 is arranged vertically, which is advantageous for smoothly dropping chip components.

Further, the holding frame 16 of the hopper base 15
Are fitted around the four lower side surfaces of the case body 25, so that the case body 25 can be prevented from being shifted from front to back and left and right.

(2) Connect the supply case 14 to the hopper base 15
The chip component 20 can be easily replenished by attaching and detaching it, and the chip component 20 can be supplied for a while even without the supply case 14 by slightly leaving the chip component 20 in the hopper base 15, so that the replenishment work can be performed more easily. Can be

The supply case 14 is connected to the hopper base 15
It is also possible to add the chip component to the supply case 14 by removing or opening the outer lid 26 in the attached state.

(3) A large number of chip components 20 are moved by the vertical movement of the hopper 13 and the separation / alignment pipe 55 is moved into and out of the hopper 13, and the chip components are taken into the through holes of the pipe 55 one by one (dropped). Thus, the chip components are separated, and the chip components can be separated, aligned, and supplied without using compressed air for separating and aligning the chip components. For this reason, breakage and contamination of the chip component due to the compressed air are eliminated, and devices such as a solenoid valve are not required, so that the device can be simplified.

(4) The chip component 2 from the entrance of the component feed path (the opening of the through-hole of the separation and alignment pipe 55) to the tip of the component feed path (the tip of the linear groove 66 of the chute tip member 67).
Since the transfer of 0 is performed by air suction, the generation of dirt in the component feeding path is small, and the scattering of dirt, dust, and the like to the outside of the apparatus is small, so that it is possible to cope with a clean room.

(5) The lower opening 25 c of the case main body 25 of the supply case 14 is fitted to the funnel-shaped space 21 of the hopper base 15.
Of the case shutter 27, and the through hole 27c of the case shutter 27 also has a shape continuous with them, so that the linear groove 30 in which the shutter 27 slides is formed.
Is filled with the edge of the through hole 27c, so that there is no dent, and the edge of the lower opening 25c and the edge of the through hole 27c does not protrude like an eave to prevent the chip component 20 from dropping smoothly. Smooth supply of the chip component 20 is not hindered from entering and exiting the funnel-shaped space 21.

(6) Funnel-shaped space 2 of separation and alignment pipe 55
1, the tip component 20 from the funnel-shaped space 21 of the hopper base 15 to the inside of the supply case 14 can be raised and lowered and slightly moved. No parts are dropped and bridges remain.

(7) Funnel-shaped space 21 of hopper base 15
Is formed inside the lower funnel-shaped surface 21a having a gentle slope and the upper funnel-shaped surface 21b having a steep slope following the lower funnel-shaped surface 21a, so that the area of the upper opening of the funnel-shaped space 21 can be small,
The width of the hopper base 15 can be reduced, and the clogging of the chip component 20 due to the bridge can be prevented.

(8) The supply case 14 is
And an outer lid 26 which can be freely opened and closed and detachably attached to the entrance of the chip component on the upper part of the case body, a case shutter 27, and an inner lid 28 which can be lowered by its own weight in the accommodation space of the case body 25. While the chip component supply device is in operation, the outer cover 26 and the inner cover 28 can be removed to supply additional chip components, and by closing the case shutter 27, the chip components can be appropriately supplied to the hopper base 15. Supply can be stopped. Further, since the chip components housed in the inner lid 28 can be pressed from above, for example, in a configuration in which the chip component supply device moves to deliver the chip components to the mounting head of the chip component mounting machine,
With this movement, it is possible to prevent a situation in which the chip component swings in the case body to cause cracking or chipping or a situation in which the chip component is charged and adheres to the case body.

(9) The shutter 73 is provided in the component pick-up opening 100 for picking up the component by the suction pin 2.
When the shutter is in the closed state, the leading chip component 20 abuts against the component stopper 71 by the air suction force, and is positioned. When the shutter 73 is in the half-open state, the external communication hole 79 communicates with the air passage communicating with the outside. As a result, the air suction is substantially disabled, and the air suction path is shut off in the fully opened state. Therefore, when the component is taken out (the shutter 73 is fully opened), unnecessary force is applied to the leading chip component 20. In addition, it is possible to accurately position the chip component 20 at the component pickup position P and to achieve a stable posture. Therefore, the chip component 20 can be stably taken out by the suction pin 2.

(10) An optical sensor 95 as a component detection sensor is provided, and when a certain amount or more of chip components 20 is present in a horizontal portion (horizontal portion) of the component feed path, the hopper up / down DC motor 42 is stopped. Then, the vertical movement of the hopper 13 is stopped, and the chip components 20 in the hopper 13 are not agitated more than necessary, so that damage to the chip components 20 can be suppressed.

When the outer shape of the chip components accommodated in the supply case is large, the number of the chip components accommodated is sufficiently ensured, and the width dimension of the supply case in the thickness direction is set so that the separation and alignment pipes can smoothly enter and exit. It is preferable to make it larger.

FIGS. 15 to 17 show other specific examples of the supply case and the hopper base used in the present invention, and show a configuration in which the width in the thickness direction is widened in view of the above points. In this case, the case body 25 of the supply case 114 has a large width dimension in the thickness direction because the outer shape of the chip component housed therein is large, and accordingly, the shape of the lower opening 25c is also changed as shown in FIG. It is larger in the width direction. Similarly, the outer lid 26, the inner lid 28, and the holding frame 16 of the hopper base 115 are also changed into a shape that fits the supply case 114. The other components are the same as the supply case 14 of the above-described embodiment, except that the dimensions are changed in accordance with the increase in the width of the case body 25 in the thickness direction. Corresponding parts have the same reference characters allotted, and description thereof will not be repeated.

As described above, the width of the supply case 114 in the thickness direction is increased, and the width of the hopper base 115 is similarly enlarged so as to be adapted to the supply case 114, so that the lower opening 25c and the funnel-shaped space 21 are formed. The width of the upper opening can be increased, and even when the external dimensions of the chip component are large, the chip component can be smoothly dropped and the clogging of the chip component by the bridge can be prevented.

FIGS. 18 to 20 show still another specific example of the supply case and the hopper base used in the present invention. By changing the structure of the hopper base, the external dimensions in the thickness direction of the entire apparatus can be increased. In this case, the width of the supply case in the thickness direction is increased.
In this case, the width W of the case body 25 of the supply case 214
19 and 20, as can be seen from FIGS.
15 and the holding frame 2 of the hopper base 215.
Reference numeral 16 denotes only the left and right sides, and the other two sides are omitted. In addition, a positioning protrusion 230 is formed integrally with the bottom surface of the case body 25 for positioning the case body 25 in the width direction.
Are formed on the upper surface of the hopper base 215. In addition,
Other components are the same as those of the supply case 14 and the hopper base 15 of the above-described embodiment, and the same or corresponding portions are denoted by the same reference numerals and description thereof will be omitted.

As described above, by making the width W of the case body 25 the same as the width of the hopper base 215, the funnel-shaped space 2
The width of the upper opening of the first component can also be increased, and the effect of preventing the clogging of the chip component by the bridge can be further improved.

In the above embodiment, the separating and aligning pipe 55 is used as a component separating member.
Instead of 5, it is also possible to use a part-separating member that is formed in a pair of half-split cylinders and has grooves formed close to or opposed to each other.

In the above embodiment, the hopper base 15
A ball plunger 18 is attached to the holding frame 16 of
Although the supply case 14 is locked, the specific structure is not limited to the ball plunger 18 but may be variously changed as long as it is a locking mechanism that causes a locking part such as a sphere to protrude with a spring or the like.

The structure of the above embodiment can be applied to both a columnar chip component and a rectangular parallelepiped chip component. If the columnar chip component is used, the through hole or groove of the component separating member is used. In addition, in the case of a chip component having a rectangular parallelepiped shape, the cross section of the component feeding path subsequent thereto may be circular, and the cross section of the through hole or groove of the component separating member and the cross section of the component feeding path subsequent thereto may be square.

Although the embodiments of the present invention have been described above, it is obvious to those skilled in the art that the present invention is not limited to the embodiments and various modifications and changes can be made within the scope of the claims. Would.

[0087]

As described above, according to the present invention,
Since the hopper is composed of a supply case for accommodating chip components and a hopper base that moves up and down by mounting the supply case, the supply case can have a simple and inexpensive structure. It can be used for distribution as a container for storing and storing parts.

Also, the supply case can be easily attached and detached to and from the hopper base to easily replenish the chip components. By slightly leaving the chip components in the hopper base, the component supply can be continued for a while without the supply case. Replenishment work can be afforded.

Further, by allowing the component separating member to enter and exit the funnel-shaped space at the base of the hopper of the hopper, the chip components in the funnel-shaped space can be dropped into the through holes or grooves of the component separating member. Therefore, the chip components can be aligned and supplied without causing component clogging and causing breakage or contamination of the chip components (since spraying of compressed air or the like is not required). Also, the tip of the alignment chute
