The gears 17c and 18c are meshed with each other in a phase state in which the respective spiral grooves 17a and 18a of FIG. 1 are correctly opposed to each other, so that the spiral grooves 17a and 18a of the pitch adjusting shafts 17 and 18 form a support space for the screw S. Has become. Also,
A pulley 17d is attached to the front end of the pitch adjusting shaft 17 so as to rotate integrally. Correspondingly, a motor 19 which is an example of a rotary drive source for rotating the pitch adjusting shafts 17 and 18 separately from the roller shafts 15 and 15 is arranged at the front part of the machine base 2. A pulley 20 is integrally attached to the output shaft 19a of the shaft 19. An endless belt B3 is wound around the pulley 20 and the pulley 17d, whereby the drive of the motor 19 is transmitted to the pulley 17d, and in response to this, the pitch adjusting shaft 17 rotates and its rotation is Since the gears 17c and 18c are transmitted to the pitch adjusting shaft 18 by the meshing of the gears 17c and 18c, the pitch adjusting shafts 17 and 18 are synchronously rotated at the same rotational speed.

On the other hand, in the shuttle block 16, as shown in FIGS. 10 (a) and 10 (b), a space formed by the annular grooves 17b and 18b of the pitch adjusting shafts 17 and 18 (a component dropping portion). ), A guide path 16b is formed which is inclined to the rear by a predetermined angle and penetrates to the lower surface side, and is for guiding compressed air supplied from a compressed air supply device (not shown). Air injection hole 1
6c is formed. The shuttle block 16 is provided with a slide member 21 that is movable along the lower surface thereof. The slide member 21 has a flexible screw feed supply hose H (hereinafter referred to as supply hose H). A hose joint 22 for connecting the is attached.
The slide member 21 is arranged in front of the rod of the air cylinder 13e, and is normally a tension spring 21a.
The hose joint 22 is positioned so as to communicate with the guide passage 16b by the urging of the air cylinder 13e.

In the present embodiment, the shuttle block 16, the slide member 21, the hose joint 22, and the air cylinder 13e constitute the above-mentioned component delivery section.

The area around the guide path 16b on the pitch adjusting shafts 17 and 18 side of the shuttle block 16 is
As is clear from FIGS. 2 and 10 (a), etc., the pitch adjusting shafts 17 and 18 cover the peripheral surfaces of the lower surface side of about half,
In addition, the pitch adjusting shafts 17 and 18 are formed in a shape along the surfaces thereof. As a result, the pitch adjustment shafts 17 and 18 side open end portions of the guide passage 16b are connected to the annular groove 17b,
The shape is formed along the annular grooves 17b and 18b of the pitch adjusting shafts 17 and 18 within a range that does not prevent the components from falling from 18b. Therefore, the annular groove 17 that is the component drop site
The gap formed at the boundary between b and 18b and the guide path 16b, which is the component introduction site, is filled so that it is possible to eliminate the bite in the gap when the component falls.

The support shaft 14 can be attached with various auxiliary equipments, and in this embodiment as well, a guide plate 23, a gate member 24, a pressing rod 25, etc. are attached to the support shaft 14. The guide plate 23 is arranged in the drum hopper 9 so as to extend obliquely on the roller shafts 15, 15.
When the drum hopper 9 is rotated, the screw S picked up by the scooping blades 10 ...
It is constructed so that it can be guided to the upper part of the surface. Further, the gate member 24 is arranged in front of the brushes 8 ... As shown in FIG.
It is composed of a circular plate formed with a cutout 24a having a shape in which only a screw S having a correct posture and supported by a neck can pass.
The pressing rod 25 is attached to the support shaft 14 via a bracket, and
5, 15 and the pitch adjusting shafts 17 and 18 are arranged above the screws S supported by the pitch adjusting shafts 17 and 18.

Next, the screw S by the component supply device having the above-mentioned configuration
The supply operation will be described. In the following description of the operation, the drum hopper 9 side is "upstream" and the pitch adjusting shafts 17 and 18 side is "downstream". First, when the screw S is inserted into the drum hopper 9 from the component insertion part and a start switch (not shown) is pressed, the motor 3 is driven and the main drive pulley 40 and the main drive gear 41 rotate. Driving pulley 4
The rotation of 0 is transmitted to the driven pulley 6 via the endless belt B1, whereby the transmission drum 5 or the drum hopper 9 is transmitted.
And the brush holding plate 7 rotate. Further, the rotation of the driving gear 41 is changed from the driven gear 42 to the pulley 4
3, the pulley 14c and the gear 1 through the endless belt B2
4b, and in response to this, the roller shafts 15, 1
5 rotates in the direction shown by the arrow in FIG. This screw S
The motor 19 is not driven and the pitch adjusting shafts 17 and 18 are not rotating and are stopped at the supply start time.

As the drum hopper 9 rotates, the screws S stored therein are picked up by the scooping blades 10 ... And fall sequentially. Among them, the screw S dropped on the roller shafts 15 and 15 is
It is sent to the downstream side sequentially by the inclination and rotation of 5,15. At this time, the screws S dropped on the guide plate 23 can also be guided to the roller shafts 15 and 15, and more screws S can be placed on the roller shafts 15 and 15. Even while the drum hopper 9 is rotating in this way, the opening 9a of the drum hopper 9 and the opening 110a of the component loading unit 11 are always in communication with each other, and thus the loading port 113a of the upper cover 113 is always provided. By inserting the screw S, the screw S can be supplied to the drum hopper 9.

In the drum hopper 9, the roller shaft 15,
The posture of the screw S mounted on the roller shaft 15 is
There are various types, such as a so-called head-hanging posture in which a screw portion is dropped between the rollers 5 and 15 and the head is supported by the roller shafts 15 and 15, and a head which is lying down on the roller shafts 15 and 15. When these screws S are sent to the position of the brush holding plate 7, the brushes 8 ... Which rotate integrally with the brush holding plate 7 are successively passing over the roller shafts 15 and 15 in this way, so that the head is in a hanging position. Screws that are not aligned (hereinafter referred to as misaligned screws) are brush 8
Are excluded from above the roller shafts 15, 15. Further, the gate member 24 is provided on the downstream side of the brushes 8 ...
Since the misaligned screws removed from the roller shafts 15, 15 are prevented from jumping out to the downstream side, they can be reliably returned to the drum hopper 9. Moreover, the gate member 24 prevents the brushes 8 ...
・ Stop on the rotational movement path of and fix this misaligned screw to the brush 8.
・ ・ It also fulfills the function of helping to be surely eliminated. As described above, the brushes 8 ... And the gate member 24 realize a structure capable of reliably eliminating the misaligned screws on the roller shafts 15, 15. The misaligned screws removed from the roller shafts 15 in this way are efficiently returned into the drum hopper 9 by the action of the tapered hole 5a of the transmission drum 5.

On the other hand, the screw S supported by the roller shafts 15 and 15 in a suspended posture moves to the downstream side through the cutout 24a of the gate member 24. In this way, only the screws S supported on the roller shafts 15 and 15 in the correct posture in the hanging state remain, and these are aligned and sent downstream. At this time, the rotation directions of the roller shafts 15 and 15 are such that the screw S is lifted up by friction.
Since the pressing rod 25 is provided on the screw S extending from the gate member 24, the pressing rod 25 prevents the screw S from rising. Further, since the shaft guide 26 prevents the roller shafts 15, 15 from running out of the core, the distance between the rotating roller shafts 15, 15 is stable over the entire length. For this reason, it is possible to stably convey the screw S without causing a problem such as dropping or biting of the screw S due to a variation in the distance between the roller shafts 15 and 15 that occurs as a result of the runout of the roller shafts 15 and 15.

Since the pitch adjusting shafts 17 and 18 are not rotating, the screws S reaching the tips of the roller shafts 15 and 15 cannot be fitted into the spiral grooves 17a and 18a, and cannot be advanced any further. Therefore, the screws S sent one after another are aligned on the roller shafts 15 and 15. When the screws S reach a predetermined amount, a photoelectric sensor (not shown) is turned on and the screws S are received. The driving of the motor 3 is stopped, and the conveyance of the screw S is temporarily stopped. Also,
When a request signal for the screw W is issued from a work machine such as a screw tightening device, the motor 19 is driven to rotate the pitch adjusting shafts 17 and 18 synchronously. As a result, the S screw reaching the roller shafts 15 and 15 at the downstream end is
As shown in FIGS. 7A and 7B, the pitch adjusting shafts 17 and 18 are fitted and supported by the spiral grooves 17a and 18a of the pitch adjusting shafts 17 and 18, and are conveyed at intervals of the leads of the spiral grooves 17a and 18a. As a result of the screw S being conveyed in this way, when the number of screws S on the roller shafts 15, 15 decreases, the photoelectric sensor is turned off, and in response to this, the motor 3 is driven again. As a result, the above-described operation is repeated and the screw S is replenished to the roller shafts 15, 15.

As described above, the pitch adjusting shafts 17, 1
When the screw S fed with No. 8 reaches the positions of the annular grooves 17b and 18b, the guide path 16b of the shuttle block 16 is reached from here.
And is supplied into the supply hose H connected to the hose joint 22. When the screw S is disengaged from the pitch adjusting shafts 17 and 18, as shown in FIG. 10A, the screw S falls onto the guide path 16b in a state in which the head is ahead, that is, the state where the head falls down from the head and tries to be reversed. . This phenomenon is
The shorter the screw S under the neck is, the more prominent it appears. On the other hand, since the guide path 16b is provided obliquely downward, the head of the screw S falling down is received before turning over. It is possible. As a result, the screw S can be transferred to the supply hose H in a correct posture with the head up. Further, due to the shape of the shuttle block 16, the clearance between the annular grooves 17b and 18b and the guide path 16b is almost eliminated, so that the screw S is hardly caught when falling, and the guide path 16b can be smoothly moved. The screw S can be transferred.

A sensor (not shown) is provided around the annular grooves 17b and 18b to detect that the screw S has reached here and dropped into the guide path 16b. In response to this, the motor 19 immediately stops,
As a result, the pitch adjusting shafts 17 and 18 are stopped and the feeding of the screw S is stopped. Further, in response to the signal from this sensor, the air cylinder 13e operates to extend the rod. As a result, the slide member 21 moves forward to connect the hose joint 22 to the air injection hole 16c. At this time,
Compressed air is supplied from the external compressed air supply device from the air injection hole 16c, and thus compressed air is injected to the hose joint 22 or the supply hose H that communicates with the air injection hole 16c. The pressure of the compressed air causes the screw S to be air-fed through the supply hose to be supplied to the work machine. Further, at this time, the lower end of the guide passage 16b is closed by the slide member 21, so that air does not blow out toward the pitch adjusting shafts 17 and 18 through the guide passage 16b. Therefore, it is possible to prevent the occurrence of a problem in which air acts on the subsequent screws S supported by the pitch adjusting shafts 17 and 18, and the screws S tilt and are caught in the pitch adjusting shafts 17 and 18. it can.

As described above, when the screws S drop from the pitch adjusting shafts 17 and 18 to the guide path 16b, if the adjacent screws S are in close contact with each other or their heads overlap each other, the following 16 together with the screw S
Although the so-called double supply problem occurs by dropping to b, in the present component supply device, the screw S has the spiral grooves 17a and 18a.
Since the leads are conveyed at a predetermined interval, the above phenomenon does not occur. That is, in the component supply device, the screws S are surely provided one by one in the guide path 16b.
It can be dropped into the air and sent by air.

[0027]

Since the component feeding apparatus according to the present invention is constructed so that the loading port of the component loading unit which is fixedly arranged is communicated with the opening end face of the rotating drum hopper, the drum hopper rotates to feed the component. Even during the work, there is an advantage that parts can be put into the drum hopper from the input port and the parts can be replenished. Therefore, the down time of the device for supplying the parts can be eliminated, and the efficiency of supplying the parts can be greatly improved. In addition, the combination of the roller shaft and the pitch adjusting shaft can widen the pitch of the parts that are aligned and conveyed to a predetermined pitch at the time of separating and supplying, so that the parts can be reliably separated and supplied one by one. In addition to being able to constantly supply components, it is possible to realize the provision of a component supply device having extremely high supply efficiency.
