The upper part of the insertion rod 18 protrudes upward from the upper surface of the rod guide 19, and the lower part thereof is inserted into the rod insertion hole 5 d of the belt cover 5 so as to be vertically movable. As shown in FIG. 5, when the movable pipe 4 is in the standby state, the upper end of the insertion rod 18 is pressed downward against the urging force of the coil spring S6 by the lower flange 4c of the movable pipe 4, and the lower end thereof is moved downward. It slightly penetrates into the concave portion 7a of the belt 7.

Hereinafter, the component supply operation in the apparatus according to the first embodiment will be described with further reference to FIGS.

In the standby state shown in FIG.
Is in contact with the stopper 20, the movable pipe 4 is at the lowered position, and the belt 7 is stopped. In addition, storage room 2a
At least a part of the chip components P therein enters into an annular concave portion (not shown) formed by the inner surface of the pipe sliding hole 2c, the outer surface of the fixed pipe 3, and the upper surface of the movable pipe 4, as shown in FIG. I have.

In this standby state, when the operating end of the operating lever 11 is pressed downward by a portion interlocked with the suction nozzle AN or another actuator, the operating lever 1 is pressed.
3 rotates counterclockwise about the pin 11a in FIG. 3, and this rotation causes the pipe driving lever 12 to rotate counterclockwise about the pin 12a. As a result, the engaging portion 12c of the pipe driving lever 12 rises from the lowered position, and the movable pipe 4 rises by the rise against the urging force of the coil spring S1. Further, as shown in FIG. 9, the rising of the movable pipe 4 raises the insertion rod 18 by the urging force of the coil spring S6, and the lower end thereof is retracted upward from the concave portion 7a of the belt 7 and the lower end of the curved passage 5a.

In the process in which the movable pipe 4 rises from the lowered position, as shown in FIG. 8, the chip component P above the movable pipe 4 and the fixed pipe 3 is released by the movable pipe 4 being pushed up, and this chip component P Are guided one by one into the upper end opening of the fixed pipe 3 while being guided by the tapered portion 4a.

As shown in FIG. 9, the chip component P that has entered the fixed pipe 3 by the upward movement of the movable pipe 4 moves downward in the fixed pipe 3 by its own weight and bends in a curved path 5a communicating with the lower end opening. And moves downward by its own weight in the curved passage 5a. The chip component P, which moves by its own weight in the curved passage 5a, is changed in posture from the vertical direction to the horizontal direction by about 90 degrees during the movement process, and the chip component P after the change in posture comes into contact with the permanent magnet 5c and is attracted. In other words, of the chip components P that move by their own weight in the curved passage 5a, the first chip component P is held at the component outlet position, and the subsequent chip components P are continuously connected behind this without any gap.

On the other hand, when the operating end of the operating lever 11 is pressed downward, the end of the ratchet driving lever 13 is also pressed downward via the coil spring S3. That is, the ratchet drive lever 13 rotates counterclockwise around the pin 11a in FIG. 1 against the urging force of the coil spring S4, and the relay link 14 is pulled rightward by this rotation, and the ratchet support plate 15 is moved. It rotates a predetermined angle in the counterclockwise direction. Thereby, the ratchet support plate 1
The ratchet wheel 17 with which the ratchet 16 of No. 5 is engaged rotates counterclockwise by a predetermined angle together with the sprocket 10, and the belt 7 moves a predetermined distance (distance L between recesses in the belt length direction, see FIG. 7). After moving forward, as shown in FIG. 5, the empty concave portion 7a stops at a position immediately below the component discharge port 5b of the curved passage 4a.

Thereafter, when the operation lever 11 is released from being pressed against the operation end, the movable pipe 4 is returned from the raised position by the urging force of the coil spring S1, and the pipe driving lever 12 and the operation lever 11 are thereby returned. Returns. Also,
At the same time, the ratchet drive lever 13 and the relay link 1
4 and the ratchet support plate 15 return, and the ratchet 16 slides along the outer peripheral groove of the ratchet wheel 17 to return to the standby position and engage again with the subsequent groove while the ratchet wheel 17 and the sprocket 10 remain at the post-rotation positions. Combine. Incidentally, taking in of the component into the upper end opening of the fixed pipe 3 is carried out in the same manner as described above even when the movable pipe 4 is lowered from the raised position.

When the movable pipe 4 returns from the raised position, as shown in FIG. 10, the insertion rod 18 is pressed downward by the lower flange 4c of the movable pipe 4 against the urging force of the coil spring S6. Accordingly, the insertion rod 18 is lowered from the raised position, and the leading chip component P held at the component outlet position is pushed downward from the component outlet 5b against the holding force based on the magnetic force of the permanent magnet 5c. The pushed-out chip component P is inserted into the recess 7 a of the belt 7.

This series of operations is carried out every time the operation lever 11 is repeatedly pressed and released from the operation end, so that the chip parts P are sequentially placed in the recess 7a of the intermittently moving belt 7 at the stop timing. Will be inserted.

The belt 7 after the component insertion advances by intermittent movement thereafter, and when the concave portion 7a accommodating the chip component P in a horizontal state reaches the component extracting position TP shown in FIG. Chip part P is suction nozzle A
By N, it is taken out to the outside in a horizontal state. Since the recesses 7a are provided at intervals in the belt length direction, the second and third chip components P supplied to the component removal position TP are taken out by the suction nozzle AN.
There is no possibility that the chip components P after the first interfere with this.

That is, since the chip component P supplied to the component extraction position TP can be taken out in a state of being completely separated from the subsequent chip component P, the leading chip component supplied to the extraction position as in the conventional device can be taken out. When taking out a chip component, it is possible to reliably eliminate the problem that the second chip component that is in close contact with the chip component causes a posture defect such as chip standing, and the chip component P supplied to the take-out position can be satisfactorily and stably placed in a proper posture. Can be taken out.

In the first embodiment, the curved passage 5
Although the permanent magnet 5c is shown as a means for holding the leading chip component P that moves by its own weight in the component discharge port position, a suction hole is provided instead of the permanent magnet 5c, and a negative pressure is applied to the suction hole. Thus, the leading chip component may be held at the same position.

In the first embodiment, the endless belt 7 is connected to the sprocket 10 and the two pulleys 8 and 9.
12 and move it intermittently.
As shown in (2), the two pulleys 8 and 9 are deleted, and instead, a belt feed reel 23 around which the endless and long belt 7 is wound so as to be able to be fed out is arranged at the position of the rear pulley 8, The belt 7 after the parts have been taken out may be wound up by a belt take-up reel (not shown).

In addition, each recess 31a has one surface in the depth direction opened on the upper surface of the belt and one surface in the length direction opened on one side surface of the belt, so that the chip component P can be inserted sideways from the opening in the depth direction. Thus, the chip component P can be inserted vertically from the opening in the length direction. The belt 31 is held by the main pulley 38 with the opening in the depth direction of the concave portion 31a facing outward.
The rear pulley 8 and the front pulley 9 are wound with a predetermined tension, and a portion between the main pulley 38 and the rear pulley 8 is disposed in the belt guide 32.

Further, a space is provided between the second guide plate 34 and the fifth guide plate 37 to expose a part insertion portion of the belt 31 after twisting, and FIG.
As shown in FIG. 7 (A), the fixed pipe 3 is mounted on the belt guide 32 such that the lower end of the fixed pipe 3 comes close to the upper surface of the belt in a non-contact manner. Further, FIGS. 18A and 18B
, The third to fifth guide plates 35 to 37
Is extended to the vicinity of the component removal position TP.

The component supply operation in the apparatus of the second embodiment will be described below with reference to the drawings used in the description of the first embodiment.

In the standby state shown in FIG.
1 is in contact with the stopper 20, the movable pipe 4 is at the lowered position, and the belt 7 is stopped. In addition, storage room 2
As shown in FIG. 4, at least a part of the chip components P in FIG. 4a enters an annular concave portion (not shown) formed by the inner surface of the pipe sliding hole 2c, the outer surface of the fixed pipe 3, and the upper surface of the movable pipe 4. I have.

In this standby state, when the operating end of the operating lever 11 is pressed downward by a portion interlocked with the suction nozzle AN or another actuator, the operating lever 1
1 rotates counterclockwise around the pin 11a,
By this rotation, the pipe driving lever 12 rotates counterclockwise around the pin 12a. by this,
The engaging portion 12c of the pipe drive lever 12 rises from the lowered position, and the movable pipe 4 moves the coil spring S1
Rise against the urging force of.

In the process in which the movable pipe 4 rises from the lowered position, as shown in FIG. 8, a chip component P located above the movable pipe 4 and the fixed pipe 3 is released by pushing up the movable pipe 4, and this chip component is released. P is the tapered portion 4a
While being guided, or directly into the upper end opening of the fixed pipe 3 one by one in the length direction. The chip component P that has entered the fixed pipe 3 by the upward movement of the movable pipe 4 moves downward in the fixed pipe 3 by its own weight.

On the other hand, when the operating end of the operating lever 11 is pressed downward, the end of the ratchet driving lever 13 is also pressed downward via the coil spring S3.

4 and the ratchet support plate 15 return, and the ratchet 16 slides along the outer peripheral groove of the ratchet wheel 17 to return to the standby position and engage again with the subsequent groove while the ratchet wheel 17 and the sprocket 10 remain at the post-rotation positions. Combine. Incidentally, taking in of the component into the upper end opening of the fixed pipe 3 is carried out in the same manner as described above even when the movable pipe 4 is lowered from the raised position.

This series of operations is carried out every time the operation lever 11 is repeatedly pressed and released from the operation end.
The chip components P are sequentially inserted into a at the stop timing.

The post-twisted portion of the belt 31 is returned to the original state by intermittent movement thereafter, but as shown in FIG. 18 (B), the recessed portion 31a returned to the original state has the opening in the depth direction with the upper surface. Since the opening in the length direction is closed by the fourth guide plate 35 in the state facing, the chip component P after insertion does not fall out of the concave portion 31a. The belt 31 returned to the original state advances by intermittent movement thereafter, and when the concave portion 31a storing the chip component P in the horizontal state reaches the component extracting position TP shown in FIG. The chip component P in the inside 31a is taken out to the outside by the suction nozzle AN in a horizontal state.
Since the recesses 31a are provided at intervals in the belt length direction, when the chip components P supplied to the component removal position TP are taken out by the suction nozzle AN, the second and third and subsequent chip components P are removed. There is no interference with this.

That is, since the chip component P supplied to the component extraction position TP can be taken out while being completely separated from the subsequent chip component P, the leading chip component supplied to the extraction position as in the conventional device can be taken out. When taking out a chip component, it is possible to reliably eliminate the problem that the second chip component that is in close contact with the chip component causes a posture defect such as chip standing, and the chip component P supplied to the take-out position can be satisfactorily and stably placed in a proper posture. Can be taken out.

In the above-described second embodiment, the endless belt 31 is wound around the three pulleys 8, 9, and 39 and intermittently moved. However, similar to the one shown in FIG. The two pulleys 8 and 9 are deleted, and instead of this, a belt feed reel 23 around which an endless and long belt 31 is reeled out is arranged at the position of the rear pulley 8, and the belt after parts are taken out is removed. 31 may be wound by a belt winding reel (not shown). Incidentally, in the above description, the term "belt" is used, but this belt also includes what is called a tape or something similar thereto.

[0052]

As described in detail above, according to the present invention,
Since the electronic component supplied to the component take-out position can be taken out in a state completely separated from the subsequent electronic components, it comes into close contact with the leading electronic component supplied to the take-out position when taking out the same as in the conventional device. It is possible to surely eliminate the problem that the second electronic component has a posture defect such as a chip standing, and to take out the electronic component supplied to the take-out position in a proper posture in a good and stable manner.
