DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention separates chips (various small electronic components) conveyed in a line by a feeder into individual recesses for chip loading of a rotor that rotates at a high speed and transfers and transfers the chips. At the same time, the chips loaded forward in the recess are directly transported by the rotation of the rotor, while the chips loaded backward are reversed from the recess through the arc-shaped reversing track provided opposite to the recess of the rotor to be turned forward from the back and returned to the recess. In this way, there is provided a chip longitudinally-conveying means for transporting all the chips in a state of being aligned forward by a rotor and feeding the chips to a next process such as a chip tape.

[0002]

2. Description of the Related Art Conventionally, one row of chips conveyed by a feeder is inserted into each recess of a rotor in which recesses for chip loading are formed at regular intervals in a circumferential portion of a disk which rotates stepwise at a high speed.
2. Description of the Related Art Automatic separation / transportation means for chips is widely used in which chips are separated, transferred, loaded, transferred and transferred, and the chips in the recesses are transferred and supplied to a chip tape or other chip holding means.

Further, some chips are separately loaded from the feeder to the respective recesses of the rotor and transported, and the chips need only be transported separately without addressing the front and rear of the chips. For example, there is a black mark or the like indicating the electrical direction at the front of the chip, and the black mark or the like is aligned in one direction, that is, aligned forward, separated and transported to one chip, and the chip is aligned. Some items must be transferred to a tape or the like.

Conventionally, the front and rear alignment of the chips is mainly performed in a ball feeder in front of and behind a single-row transfer feeder (straight feeder) facing the concave portion of the rotor. Chips are randomly input, and the chips are aligned and conveyed in a line by vibration, and the backward (or forward) chip is prepared so as to be returned to the ball again by the front / rear discrimination sensor provided around the chip, so that the chips are aligned forward (or backward). Are fed to a single-row transport feeder, and then separated and loaded one by one into each recess of the rotor.

However, since the above-mentioned chip front-rear alignment means is integrally formed as a part of the ball feeder, the ball feeder is extremely expensive as a special custom-made product. In addition, since the determination is made in the middle of the alignment of one row by vibration, the forward and backward directions of the chips are almost half, and almost half of the aligned one row is returned to the ball. Efficiency (number of conveyed pieces, speed) is reduced to about ２, which hinders speeding up of automatic separation and transfer of chips.

[0006]

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned conventional problems by eliminating the above-mentioned conventional means and providing a reversing track as a means for aligning the front and rear of the chip at a position relative to the recess at the set position of the rotor. It is an effective solution.

[0007]

According to the present invention, the chips conveyed in a row by a feeder are suction-loaded into each of the recesses for loading the chips of a rotor which rotates at a high speed by the suction force of suction means provided in the recesses.

When the rotor is rotated and the recess loaded with the chip comes to a position facing the entrance of the reversing track, a direction detecting sensor detects the front-back direction of the chip, and the chip is loaded forward by the sensor. While rotating, the rotor is rotated and transported as it is.

The backwardly loaded chip is blown from the recess to the entrance of the reversing track by the blast force of the blowing means, and is blown to the exit of the reversing track in the shape of an arc. Prepare to load forward with inspiration,

The passage sensor detects the blowing from the recess of the chip to the entrance of the reversing track and gives a signal for rotating the rotor. The passage sensor detects the suction loading from the exit of the reversing track to the recess. Be prepared to give a signal to rotate the rotor

The timing of the blast from the blast means and the timing of the rotation of the rotor are controlled by the detection signals of the above sensors, so that all the chips loaded in the respective recesses of the rotor are conveyed while being aligned in the forward direction. The object has been solved by a chip front-back direction aligning / conveying means.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. The chips t conveyed in one row by the feeder 1 are suction-loaded into the respective recesses 3 for loading the chips of the rotor 2 rotating at high speed by the suction force of the suction means 4 provided in the recesses 3.

When the rotor 2 rotates and the concave portion 3 loaded with the chip t comes to a position facing the entrance 7a of the reversing track 7, the direction detecting sensor 5 detects the front-back direction of the chip t, and When the tip t is loaded forward in the recess 3, the rotor 2 is rotated and conveyed as it is, while when the tip t is loaded backward, a signal for blowing from the blowing means 6 of the recess 3 is given.

The backwardly loaded chip t is blown from the recess 3 into the inlet 7a of the reversing track 7 by the blast force of the blasting means 6 and is blown out to the outlet 7b of the reversing track 7 in a circular arc shape, whereby the tip is reversed from the rear to the front. Preparing to be loaded forward by the suction force of the concave portion 3 facing the outlet 7b,

The passage sensor 8 detects the blowing from the recess 3 of the tip t into the entrance 7a of the reversing track 7 to give a signal for rotating the rotor 2, and also provides a signal from the exit 7b of the reversing track 7 to the recess 3. In order to detect the suction load by the passage sensor 9 and provide a signal for rotating the rotor 2,

The timing of the blast from the blast means 6 and the timing of the rotation of the rotor 2 are controlled by the detection signals of the sensors 5, 8 and 9, and the rotation of the rotor 2 is controlled.
A chip front and rear direction aligning / conveying means characterized in that all the chips t loaded in each of the concave portions 3 are transported in a state of being aligned in a forward-facing manner.

The reversing track 7 is formed such that a track passing through the tip t is formed in an arc shape, and its tip is formed at an entrance 7a.
The rear end is an outlet 7b, and the inlet 7a is provided opposite to one of the recesses 3 at the set position of the rotor 2,
The recess 3 is provided with a recess 3 at least one step behind the recess 3 and the outlet 7b. The tip t entering the inlet 7a of the reversing track 7 from the recess 3 of the rotor 2 passes through the arc-shaped track and exits. 7b, the front and rear directions thereof are reversed, and in this state, the reversing track is provided so as to be reloaded into the recess 3 by the reversing track. Are all transported in a state of being loaded in a forward direction.

The loading of the tip t into the recess 3 of the rotor 2 from the recess 3 of the feeder 1 rotor 2 or the outlet 7b of the reversing track 7 is performed so as to be suction loaded by the suction force of the suction means 4 provided in the recess 3. The suction means 4
Are provided with openings of the respective intake grooves 4a radially formed on the lower surface of the rotor 2 in the respective recesses 3 so as to always take in air from the openings.

The tip t is blown and fed from the concave portion 3 of the rotor 2 to the entrance 7a of the reversing track 7 by the blast force of the blasting means 6, and the blasting means 6 is connected to the entrance 7a of the reversing track 7. A blow port 6a for blowing air is provided in the opposed recess 3 so as to be blown out from the blow port 6a to blow out the chip t according to a signal from the direction detection sensor 5.

[0020]

[Function] First chip t transported in one line by feeder 1
Is suction-loaded into the recess 3 by the suction force of the suction means 4 in the recess 3 of the rotor 2.

Next, when the rotor 2 rotates stepwise and the concave portion 3 loaded with the chip t comes to a position facing the entrance 7a of the reversing track 7, the direction detecting sensor 5 detects the direction (forward or backward) of the chip t. And the sensor is
When the tip t is loaded in the recess 3 in the forward direction, the rotor 2 rotates as it is, and when the tip t is loaded in the recess 3, a signal for blowing from the blowing means 6 in the recess 3 is given.

Therefore, when the chip t is loaded backward, air is blown out from the blowing port 6a of the blowing means 6 to blow the chip t in the concave portion 3 into the inlet 7a of the reverse track 7, and the chip t is The gas is blown through the reversing track by the fumarolic force, during which the direction is reversed and reaches the outlet 7b.

The passage sensor 8 detects that the tip t has been blown into the inlet 7a from the recess 3 by the blowing means 6, and gives a rotation signal to the rotor 2, and the rotor 2 rotates, and the empty recess 3 is removed. When the tip t reaches the relative position of the outlet 7b, the tip t reaching the outlet 7b is suction-loaded by the suction means 4 (constant suction) of the concave portion 3.

The passage sensor 9 detects that the tip t is loaded into the recess 3 from the outlet 7b, and gives a rotation signal to the rotor 2.

Even if the recess 3 into which the chip t is loaded forward is located at a position relative to the entrance 7a of the reversing track 7, the signal from the direction detecting sensor 5 does not exist, so that the blowing means 6 does not operate.
Even when the chip is conveyed as it is and comes to the relative position of the outlet 7b, since the forward-facing chip t is already in the concave portion 3, the chip does not collide with the chip and is not loaded.

As described above, all the chips in the respective concave portions that have passed the reverse track position of the rotor are aligned in the forward loading, and are transported to the next process.

[0027]

[Effect] Since the direction of the chips can be reversed by the action of the reversing track provided relatively to the circumference of the rotor, all chips separated and loaded one by one from the feeder to the concave portion of the rotor have the same direction (forward or backward). There is an excellent effect that it can be arranged in a state where it is aligned and conveyed to the next process.

Since it is only necessary to provide the arc-shaped inverting track and the sensor, the cost is low. In addition, since the direction of the inverting track is reversed from the entrance to the exit of the inverting track, the risk of malfunction may be caused. There is no at all.

Further, since the chip reversing process can be performed in parallel during the high-speed step rotation of the rotor, there is no hindrance to the high-speed separation and transport function of the rotor.
