Can be moved inward against the urging force of the coil spring S6 to hold the second component P from the top again.

The operation of the above-described component supply device will be described below. When the leading part P on the belt 7 is taken out from the outlet 5a2 by the suction nozzle or the like, as shown by a white arrow in FIG. It is pressed backward by the driving device.

In the initial state where the movable pipe 4 is at the lowered position, as shown in FIG. 4, an annular pocket E is provided between the upper end of the movable pipe 4 and the inner surface of the sliding hole 2c and the outer surface of the fixed pipe 3.
Is formed, and a small number of components P enter the annular pocket E.

When the operating portion of the operating lever 10 is pressed backward from this initial state, as described above, the movable pipe 4 is raised from the lowered position by a predetermined stroke by the rotation of the first drive lever 11, and The upper end enters the storage chamber 2a of the hopper 2.

In the process of moving the movable pipe 4 from the lowered position to the raised position, as shown in FIG.
As a result, the component P in the annular pocket E is lifted upward and the storage component in the storage chamber 2a is opened, and even if there is a component P lying on the fixed pipe 3, the component P is pushed away from the same position. In the same process, the storage component P is vertically taken into the upper end opening of the fixed pipe 3 by utilizing the inclination of the upper end guide surface 4a of the movable pipe 4, and falls in the fixed pipe 3 under its own weight while keeping the same orientation, and the downward movement is performed. It is led to.

When the operation lever 10 is released from being pressed against the operation portion, the operation lever 10 and the first drive lever 11 are pivotally returned to the initial position by the biasing force of the return spring 12, as described above. The movable pipe 4 is also a coil spring S1.
With the urging force of (1), it returns from the raised position to the lowered position.

In the process of moving the movable pipe 4 from the raised position to the lowered position, as shown in FIG.
Again, a small number of parts P enter again, and the whole stored parts descend. Also in this process, the storage component P is vertically taken into the upper end opening of the fixed pipe 3 by utilizing the inclination of the upper guide surface 4a of the movable pipe 4, and falls in the fixed pipe 3 under its own weight while keeping the same orientation. It is led to.

As described above, the parts are taken into the fixed pipe 3 during both the ascending and descending steps of the movable pipe 4. Part P taken vertically into fixed pipe 3
Moves down the fixed pipe 3 under its own weight and
b2 in the same direction, fall in the vertical passage 5b2 under its own weight, one end of which abuts on the upper surface of the belt 7,
Subsequent parts P are stacked vertically on this.

On the other hand, when the operating portion of the operating lever 10 is pressed backward, as described above, the feed lever 14 rotates through the second drive lever 13 by a predetermined angle,
Then, the first ratchet wheel 15 and the front pulley 8 rotate by a predetermined angle, and the belt 7 moves forward by a distance corresponding to the rotation angle, preferably a distance larger than the length of the component P.

In the process in which the belt 7 moves forward by a predetermined distance, as shown in FIG. 5, a part P abutting one end on the upper surface of the belt 7 is pulled forward by frictional resistance, and rolls over the belt 7. Next, the next component P comes into contact with the upper surface of the belt 7 at one end. The intermittent advance of the belt 7 is the outlet 5a.
2 is repeated each time the leading part P is taken out from the belt 2, the lowermost part P in the vertical passage 5 b 2 is successively led out onto the belt 7 while undergoing a similar roll-over action, and a plurality of parts P While being aligned by the linear grooves 5b1 and 5a1, they are vertically aligned on the belt 7 in a line, and are conveyed forward in the aligned state in accordance with the intermittent movement of the belt 7.

When the first ratchet wheel 15 rotates together with the front pulley 8 to move the belt 7 forward, as described above, the second ratchet wheel together with the first ratchet wheel 15 is used. Similarly, the stopper operation plate 17 is rotated as shown in FIG.
The part stopper 9 is turned by the rotation of the
Abuts on the front end of the linear groove 5a1 to secure a desired part stop position. That is, the components P conveyed by the belt 7 stop when the leading component P abuts against the component stopper 9, and are vertically aligned on the belt 7 in a line without any gap, and the component movement is performed by the component stopper 9. After the regulation, only the belt 7 moves forward by utilizing the sliding of the component contact surface.

After the second ratchet 16 and the first ratchet 15 have rotated counterclockwise by a predetermined angle (one mountain), as described above, the stopper operation plate 17 is moved to the initial position. As shown in FIG. 6, the tip of the holding pin 19 projects into the linear groove 5a1 by the return of the rotation of the holding lever 18, and the second component P from the top is held, as shown in FIG. Is separated from the front end of the linear groove 5a1 of the component guide 5, the leading component P moves forward together with the component stopper 9 by the magnetic force of the permanent magnet M, separates from the second component P, and A gap is forcibly formed with the second component P.

As shown in FIG. 6, the leading component P is taken out by the suction nozzle or the like when the component stopper 9 is displaced forward and the leading component P is completely separated from the second component P. Therefore, even when the first component P and the second component P are stuck or stuck due to the influence of moisture or the like, this can be resolved and the first component P can be taken out very well.

As described above, according to the above-described component supply device, the first stopper 20a for defining the operation limit position of the operation portion of the operation lever 10 and the operation lever 10 are urged in the direction opposite to the first stopper 20a. Since the return spring 12 and the second stopper 5c2 for defining the initial position of the operation lever 10 are provided, the operation portion of the operation lever 10 is simply pressed against the urging force of the return spring 12 so that the operation lever 1
0 can be operated in the range from the initial position to the operation limit position to secure a predetermined amount of displacement between the movable pipe 4 and the feed lever 14 and the driving portion of the ratchet mechanism.
By simply releasing the pressure on the operation lever 10, the operation lever 10 can be automatically returned to the initial position by using the biasing force of the return spring 10.

In other words, the operation of the movable pipe 4 and the feed lever 14 in a predetermined direction and amount can be given to each of the movable pipe 4 and the feed lever 14 by simply applying a simple operation to the operation lever 10 from the outside. There is no need to control these operations on the device side, and there is an advantage that a high-precision device is not required as a driving device, and also an advantage that stable supply of expected parts can be achieved even when the supply speed is increased. There is.

Further, the operating lever 10 is spring-biased clockwise as viewed from the side of the apparatus, and the operating portion of the operating lever 10 is pressed counterclockwise from the initial position, thereby causing the first drive lever 11 to move. Since the movable pipe 4 can be moved in the counterclockwise direction and the feed lever 14 can be moved in the clockwise direction via the second drive lever, the operation lever 10 and the first and second drive levers can be moved. There is an advantage that the lever structure including the levers 11 and 14 can be made compact, which can contribute to downsizing of the device.

Further, since the operation portion of the operation lever 10 is located inside the outline of the apparatus viewed from the side of the apparatus, the operation lever 10 does not hinder the installation of the apparatus or the removal of components by a suction nozzle or the like. It has advantages and is extremely useful when installing a plurality of devices side by side.

Further, a component stopper 9 for stopping the leading component P on the belt 7 at a predetermined position, a permanent magnet M for attracting the leading component P to the component stopper 9, and a component stopper 9 at the same position as the component stopping position. A stopper displacing mechanism for displacing the part to a component take-out position remote from the position.
The driving of the stopper displacement mechanism (rotation of the second ratchet wheel 16) is performed using the movement imparted to the component 4, so that a complicated mechanism for displacing the component stopper 9 is unnecessary, and
There is an advantage that the mechanism can prevent the suction nozzle or the like from obstructing the removal of components, and the mechanism can prevent the apparatus from being enlarged.

In the above embodiment, the component guide is provided with the second stopper for defining the initial position of the operation lever (first drive lever). However, instead of removing this, the first stopper is used. A second stopper having the same structure as that described above is provided on the device frame including the bracket, and the initial position of the operation lever (first drive lever) is defined by the second stopper that directly contacts the operation lever under the bias of the spring. Good.
