Description

[0001]
BACKGROUND OF THE INVENTION
In the process of the present invention, chips (various small electronic components, for example, chip registers) are separately loaded into each recess of a rotor and conveyed to the next process. Provided is a chip front-and-back alignment transport device in which chips are aligned (aligned) in the front (or back) direction.
[0002]
[Prior art and its problems]
Conventionally, chips that are transported in a single row by a feeder or the like are separated and transferred and loaded into each recess of a rotor in which recesses for chip loading are formed at equal intervals around the circumference of a disc that rotates intermittently at high speed. An automatic chip separation / conveying means is widely used in which the chip in the recess is transferred to one chip holding means such as a chip tape.
[0003]
Also, some chips need only be separated and transported to one chip without causing problems, and for example, all chips are aligned in the front (or back) direction, such as a chip register. Some must be transported separately and transferred to a chip tape or the like in that state.
[0004]
The above-described front / back alignment is conventionally performed mainly in a ball feeder in front of a single-line conveying feeder (straight feeder) opposed to the concave portion of the rotor, and the ball feeder randomly inserts a large number of chips into the ball. In addition to aligning and conveying it in a row by vibration, it is equipped with a tip (or front) tip that returns to the ball again by the front / back discriminating sensor provided around it, and only those that are aligned in the front (or back) direction. It is sent to the one-line transport feeder, and then one is separately loaded into each recess of the rotor.
[0005]
However, since the above-mentioned chip front / back alignment means is integrally formed as a part of the ball feeder, there is a problem that the ball feeder is extremely expensive as a special custom product, Since the front and back of the chip are divided in half during the alignment in line with vibration, almost half of the aligned chip is returned to the ball, so the efficiency of the chip aligned transfer (transported number, speed) Has been reduced to about ½, which hinders the speeding up of the automatic separation and transfer of chips.
[0006]
[Object of the present invention]
In view of this, the present invention carries out tip-to-back inversion alignment by rotating a disc wheel provided close to the rotor while the tip is separated and loaded into each recess of the rotor and rotated and conveyed to the next process. It is an object of the present invention to provide an apparatus as described above, and to improve the efficiency of chip front-and-back alignment and conveyance as compared with the prior art.
[0007]
[Means for solving the problems]
In the present invention, chips that are conveyed in a row by a feeder or the like are separately loaded into each recess of a rotor in which recesses for chip loading are formed at equal intervals around the circumference of a disk that rotates intermittently at high speed. In an automatic chip separating and conveying apparatus in which the conveyed chips are transferred to one chip tape or other chip holding means.
[0008]
A slit of a size that fits each chip is formed at the left and right symmetrical positions of the circumferential part of the disk car that is pivotably pivoted, and the left and right slits are communicated with each other through communication holes. With a tip that can move freely,
[0009]
The disc wheel is placed close to the circumference of the rotor, and the slit on the right side is installed in a state of being fitted and matched with the recess of the rotor, and the recess can pass through the slit of the disc wheel when the rotor rotates. In addition, it is equipped with a fumarole in relation to the slit on the left side of the disc wheel,
[0010]
The front and back of the chip in each concave part of the rotor are discriminated by a sensor, and when the concave part of the back (or front) chip fits into the slit on the right side of the disc wheel and the chip moves into the slit, the disc wheel is moved 180 ° Rotate and rotate the right slit to the left to invert the tip to face up (or back), and blow the tip in the left slit toward the right slit with the blast force of the air outlet, and at the same time the rotor The chip is restored and loaded in the slit on the right side, that is, in the recess of the rotor by the suction force of the inlet of the recess, and then the chip is transported to the next position by passing through the slit in the right side by the rotation of the rotor.
[0011]
In addition, if the chip is transferred into the slit when the concave portion of the front (or back) tip is fitted and matched with the slit on the right side of the disc wheel in the sensor discrimination, the disc wheel is not rotated and the tip Let the recess pass through the slit as it is,
[0012]
Therefore, the problem is solved by a chip front-and-back aligning and transporting device characterized in that all the chips in each recess of the rotor are transported while being aligned in the front (or back) direction.
[0013]
【Example】
Next, examples of the present invention will be described. (FIGS. 1 to 4)
Chips t transported in a row by the feeder 2 are separately loaded into each recess 3 of the rotor 1 in which recesses 3 for chip loading are formed at equal intervals around the circumference of a disk that rotates intermittently at high speed. In the automatic chip separation / conveying apparatus, the transferred chip t is transferred to the chip tape 4 and other chip holding means.
[0014]
Slits 6 and 6 having dimensions of inserting one chip t are formed at left and right symmetrical positions of the circumferential portion of the disc wheel 5 that is rotatably pivoted, and a communication hole is formed between the left and right slits 6 and 6. 6a is connected between the left and right slits 6 and 6 so that the tip t can move freely,
[0015]
The disc wheel 5 is placed close to the circumference of the rotor 1 and the slit 6 on the right side is installed in a state where the disc wheel 5 is fitted and matched with the recess 3 of the rotor 1. Provided so that it can pass through the slit 6, and provided with an air inlet 7 in opposition to the left slit 6 of the disc wheel 5,
[0016]
The front and back of the chip t of each concave portion 3 of the rotor 1 is discriminated by the sensor 8, and the concave portion 3 of the chip t facing the back (or front) is fitted and matched with the slit 6 on the right side of the disc wheel 5. When the disc wheel 5 is moved in, the disc wheel 5 is rotated 180 °, the right slit 6 is rotated to the left to invert the tip t so as to face up (or back), and in the left slit 6 by the jet force of the jet port 7. The tip t is blown toward the slit 6 on the right side and at the same time, the tip t is restored and loaded into the slit 6 on the right side, that is, into the recess 3 of the rotor 1 by the suction force of the suction port 9 of the recess 3 of the rotor 1. The rotation of the rotor 1 causes the chip t to pass through the right slit 6 and be conveyed to the next position.
[0017]
Further, when the concave portion 3 of the front (or reverse) tip t is fitted and coincides with the slit 6 on the right side of the disc wheel 5 by the discrimination of the sensor 8 and the tip t is transferred into the slit 6, the disc wheel 5 So that the recess 3 of the chip t passes through the slit 6 as it is,
[0018]
Thus, the chip front / back alignment transporting apparatus is characterized in that all the chips t in the respective recesses 3 of the rotor 1 are transported while being aligned in the front (or back) direction.
[0019]

[0020]
[Action]
During the high-speed intermittent rotation of the rotor 1, the circumferential portion of the rotor 1 provided with the recess 3 rotates through the slit 6 of the disc wheel 5.
[0021]
When one chip t is separately loaded from the feeder 2 into each recess 3 of the rotor 1, and the front and back of the chip t are detected by the sensor 8 while being conveyed by the rotation of the rotor 1, for example, when the chip t is aligned face up When the tip 3 is detected and the concave portion 3 is fitted and matched with the slit 6 on the right side of the disc wheel 5 and the tip t is transferred into the slit 6, the disc wheel 5 is rotated 180 ° and the slit 6 on the right side is rotated. Is rotated to the left to invert the tip t so that the tip t is turned upside down, and the tip t in the left slit 6 is blown toward the right slit 6 by the squirting force of the squirt port 7 and at the same time the recess 3 of the rotor 1 The tip t is restored and loaded into the right slit 6, that is, into the recess 3 of the rotor 1 by the suction force of the inlet 9, and then the tip 1 passes through the right slit 6 by the rotation of the rotor 1 to the next position. Carry.
[0022]
Further, when the concave portion 3 of the front-facing tip t is fitted and matched with the slit 6 on the right side of the disc wheel 5 by the discrimination of the sensor 8 and the tip t is transferred into the slit 6, the disc wheel 5 is not rotated, The concave portion 3 of the chip t is conveyed through the slit 6 as it is.
[0023]
Due to the action described in the above paragraphs 0021 and 0022, all the chips t of the respective recesses 3 that have passed through the position of the disc wheel 5 are conveyed in a state of being aligned face up, and transferred to the next step, for example, chip tape. It is what is done.
[0024]
【effect】
As described above, the present invention is provided by inserting the slit on the right side of the disc wheel formed with the slit into the concave portion of the rotor so that the circumferential portion thereof passes through the slit when the rotor rotates, and from the concave portion. Since the disc wheel is rotated 180 ° when the front and back of the chip transferred to the slit are reversed, the rotation and synchronization of the rotor is performed during the separation and transfer of one chip by each concave portion of the rotor that rotates at high speed intermittently. Thus, it is possible to perform high-speed reversal alignment of the chips by the disc wheel, and therefore, there is a great effect that the front-rear alignment conveyance of the chips can be performed at a high speed doubled as in the past.
