There are 12783 and others, which are put to practical use. However, since the former device requires an air compressor to generate compressed air, it is inconvenient to carry, and the screw holding when the driver body is tilted downward is magnetized. Since there is a large reliance on the magnetic force of the driver bit, there is a concern that the screw will fall off due to the tilting state and vibration of the machine body, and it is also difficult for the screw shaft and the central axis of the driver bit to be perfectly aligned. In some cases, screwing is not performed. Further, in the latter screw supply method using a screw holding strip, since the screw tip end portion held by the holding strip is exposed and continues in a strip shape, there are some surfaces that hinder work. In addition, it is difficult to use the loose normal screws, and it is customary to purchase and use the screws with the screws already inserted in the holder, which is expensive.

The cartridge type screw aligning and accommodating device is detached from the supporting base body on the side wall of the main body, the lid is opened, the operation knob of the pullback plate is pushed, and the sliding opening at the lower part of the side wall of the device is slid to the screw extracting side. The locking projection of the pullback plate is locked to the locked part of the push plate and the screw push plates are pulled back together at the same time, and the pull plate is inserted into the lock opening at the end of the sliding opening and the screw push plate is locked together. Place it fixed. In this state, when a loose screw is dropped on the surface of the groove forming portion, the screw is guided by the inclined surface portion of the component member, the screw shaft is inserted into the forming groove, and the screw head is supported by the inclined surface portion. After inserting the desired number of screws, remove the screws that did not fit in the groove, cover the device, and lock the lid. The gap between the lid and the screw head does not hinder the sliding movement of the screw, and the screw does not fall off regardless of the orientation of the machine body. When the operation knob of the pullback plate is moved in the longitudinal direction in this state and the screw pressing plate is removed, the screw pressing plate is pushed by the spring and the screws are aligned with the screw extraction side dam plate. The support base is inserted into the device in which the screws are aligned and housed, the locking plate of the traction spring is locked to the support base, and the stopper claw on the base is hung on the rack on the side of the device to allow the sliding movement of the device. stop. The device supported by the support base is contact-connected with the screw introduction rail of the next-stage screw delivery mechanism, and when the device is attached, the projecting locking portion from the contact surface on the screw introduction rail side is covered by the barrier plate. The dam plate slides on the locking piece to open the screw extraction side. The screw is pushed by the screw pressing plate, and only one screw is fitted to the screw fitting portion of the rotary columnar body provided at the end of the screw introducing rail of the next stage mechanism. In such a state, when the screws held in the first stage screw retainer of the screw transport path are fed and run out, the switch mechanism composed of the retainer and the feed claw sliding base are in the return state position. When the switch and the switch are activated, the slidac is urged so that the mounting base of the screw pressing structure slides on the guide rail, and the screw separating claw of the screw pressing structure separates the next contact screw. , Push the screw shaft on the hypotenuse face of the screw pushing arrangement. When the screw fitted to the side surface is pushed, the rotary columnar body rotates and the screw is released from the fitting surface in the opposite direction and slides between the rails.
The screw is pushed between the rotary crossing bodies which are located between the screw introducing rail end and the screw conveying path entrance and intersect with each other by the spring body. Obtains the momentum of pushing the screw holders into each other by the restoring force of the crossing body, and the switch mechanism is held by the holders in the screw conveying path.

When the screw is thus extracted and the last screw in the screw groove is pushed out, the switch operating piece at the bottom of the screw pressing plate actuates the switch of the forward feeding mechanism, and the sliderac is urged to the tow rod. The rotating ring at the end of the feed claw arm is pulled by the ring pulling rod in the sliding support frame which is connected. The feed claw attached to the arm body of the stopper-claw works in a lever-like manner and is locked by the stopper claw that is locked by being pulled by the traction spring at the end of the arm body and pressed against the rack. Remove. When the screw arrangement storage device with the stopper-claw disengaged from the rack is pulled by the pulling spring and slidably moved, the feed claw also slidably moves by the set value in a state where the feed claw is locked in the rack inside the rack. The rotating ring of the feed claw also rotates on the ring pull rod. At this time, the screw introduction
The locking projection on the front of the screw is released from the locked piece of the weir plate stopped by the stopper on the side of the screw organizing and storing device, and the weir plate is pulled by the spring in the slide rail and the screw is extracted. Close the face. Further, the projecting locking portion is locked to the locked piece of the next barrier plate and slides the barrier plate in accordance with the movement of the device.

Next, off delay. When the set time of the timer elapses, the bias of the sliderac is released, the stopper operating part is pushed to the rack side by the spring of the guide support part, the stopper claw engages with the rack again, and stops the movement of the device and feeds it at the same time. The pawl comes off and the return spring of the feed pawl returns it to its original position. The extracted screw enters the screw conveying path as described above.

Next, the screw tightly held in the screw holder in the screw conveying path is pushed by the screw head at the vertical surface of the screw feed claw and removed from the screw holder, and moved to the next screw holding piece. To do. The stroke operation of the screw feed claw is repeated intermittently until the screw advances to the hypotenuse part of the screw holding piece at the final stage position of the screw transport path and the screw detection sensor operates again. Wait for the plane to return. Further, the screw receiving the stroke of the screw feed claw pushes the hypotenuse part of the screw holding piece as well as the screw feed claw, and the pushed screw holding piece passes the retracting screw and the screw feed claw to the base side. The screw feed claw that moved between one screw holding piece by one stroke operation, when the sliderac is released from its bias and returns, the screw head locked to the screw holding piece and the screw holding piece in the protruding state The hypotenuse is pushed by one piece, and the passage side is restored while retracting to the base body side.

When the screw is moved to the end of the screw conveying path by a few strokes of the screw feed claw, and the adhesive mounting machine is at the return position and the screw is not tightly attached to the screw narrowing piece, two switch sensors are used. -Is operated and the screw is pushed between the screw tightening holding pieces of the screw mounting device by the stroke of the screw feeding claw.

Next, an embodiment of a spiral type screw conveying mechanism which is a screw feeding mechanism exclusively for screws having a flat screw head and a screw delivering mechanism connected to the spiral type screw conveying mechanism will be described. The screw extracted from the pre-stage device is guided by the contact surface portion of the support base and the screw introduction portion of the screw holding attachment and is fitted into the screw fitting portion of the rotating cylinder, and the curved surface of the screw holding attachment is rotated as the cylinder rotates. The portion moves to enter the screw advancing passage entrance of the screw conveying mechanism connected thereto, and activates the switch on the side wall of the passage to stop the rotation of the rotating columnar body. The fin of the rotating spiral body is engaged with the screw head fitted to the screw fitting portion and slid down from the screw fitting surface and taken into the screw advancing passage. The switch operates again, the rotating cylinder rotates, the screw fits on the screw fitting surface, and the screw is repeatedly transferred to the screw transport mechanism side. The screw taken in the screw advancing passage advances in the target direction by the rotation of the spiral fin, and the rotation of the spiral body continues until the screw advances to the sensor position at the terminal end,
When the screw mounting machine is in the return position and the screw is not held tightly, the drive circuit operates by the return detection switch and the screw tightness detection switch, and the spiral body further rotates to screw the screw into the screw mounting machine. Push in between the screw-holding pieces to hold them tightly.

The screw is guided between the screw narrowing holding piece in contact with the passage outlet and between the screw guide pieces protruding from the inner wall of the main body, and the screw shaft is inserted and supported between the two pairs of screw narrowing holding pieces of the screw mounting machine. Activate the screw tightness detection switch at the tip of the screw. Then, the screw is held by the screw mounting machine, the support sleeve and the driver bit are completely restored, and the drive signal is added to the drive signal by the circuit signal when the main motor and the driver bit support selecting device are stopped. When urged, the operation knob connected to the rod swings, and when the turning knob connected in the main body swings, the turning arm supports the arm supporting shaft portion as a shaft. Rotate toward the screw mounting cavity of the hub, press the screw shaft against the screw receiving opening of the screw mounting holder, push open the screw holder, and insert the screw in the center. The set time of the delay timer elapses, the bias of the slidac is released, the screw mounting machine is pulled by the return spring and starts to return, and the mounting screw tries to return together, but it is blocked at the intersection of the screw mounting cage and the screw is stopped. The rest is retained. When the screw mounter returns to the return position and operates the switch sensor, a return signal enters the timing circuit, and the timing circuit issues a signal indicating that the screw mounter has mounted the screw and returned to the main motor start switch signal. And the contactless switch is closed via the interlock circuit to start the main motor.

When the main motor is started, the arm of the pantograph mechanism with the engaging weight is unfolded, and the end of the telescopic clutch shaft is pushed out by the mounting base and at the same time the propelling screw of the propelling screw cylinder is engaged. The combined engagement weight rotates forward, and the front end clutch part moves and engages with the clutch part of the driver bit.

As the driver bit advances, the coil springs surrounding it are sequentially compressed and the supporting sleeve is compressed.
The sliders also slide with each other, and the overall length shrinks.
The bit rotatably moves in the support sleeve and catches the screw head held therein.

The bit tip, which is rotated forward, is gradually pushed into the holding center hole, and the protruding tip portion is guided by the screw introduction surface of the next screw holder, the screw shaft is inserted into the center hole, and is held. The screw clamp holder is pushed to both sides by the screw head and the driver-bit shaft so that the screw and the driver-bit pass through. Furthermore, the screw holder that holds the screw shaft that is rotating further gradually spreads to both sides as the screw advances, and similarly the screw head passes after the screw shaft is held by the next-stage screw holder. . In this way, the screw continues to rotate while being linearly attached to the driver bit, and when most of the screw shaft length enters the holding part of the sliding retainer at the front end of the support sleeve, the screw around the retainer is surrounded. The sliding support cylinder slides on the inner wall of the supporting sleeve and moves the end of the sleeve while compressing the return spring. As the screw hits the target material and is screwed in, the scat-shaped contact portion of the slide retainer contacts the surface of the target material and spreads in all directions, and the tubular screw holding portion also expands. The holding container is also spread by the screw head and the driver bit from the screw introducing portion side, and holds the screw until the screw shaft is sufficiently screwed into the target material.

When the start switch near the machine is released and the power is turned off after the screws have been screwed in, the short switch interlocked with the start switch works to quickly stop the motor rotation, and the pantograph mechanism is engaged. The compound weight also loses its centrifugal force and is disengaged by the return spring attached to the arm, and the retractable clutch shaft is also pulled back by the return spring, and the shaft end retreats rapidly, but the shock absorbing spring softens the shock. . Also, support sleeve and driver
The bit also returns to the return position with the return spring. Further, the sensor operates and the drive circuit operates, and the above stroke operation is repeated.

Further, the reverse gear insertion operation, the driver
The bit selection operation and the vibration work conversion operation have been described in the relevant portions of the configuration section, and will not be newly described.

Next, the flow of the program operation when the automatic production system is connected to the computer will be described. First, extract the driver data from the input work data, reset the counter, count the number of drivers according to the usage order, divide the data if it is larger than the number that can be embedded in the main unit, and send them to the next work program, Each driver is compared with the memory data whether it is actually installed on the support desk, and if it is not installed, the unevenness is output and displayed, and according to the display, it is manually installed on the desk and the memory data is re-registered. . Repeat this operation for the number of instructions to install the driver bit. Next, read the data of the driver to be used first in the driver driving program, set the number of times the driver is used (the number of screw driving) and reset the counter, and also position the pulse motor of the positioning device so that the driver bit axis goes straight to the driving position. The step signal is set to the feed position, the step signal is sent to the pulse motor of the screw transport path connection switching device, the screw transport path is connected to the requested screw supply source, and the screw is fed. Also, during this time, the number of steps up to the use position of the driver bit on the support desk is counted, and the step operation is performed to wait at the use position. Then, the screw enters the driver body, detects the signal held by the screw holding piece of the screw mounting device, sends a movement pulse to the movement pulse motor of the screw mounting machine, and causes the screw mounting holder in the sleeve to hold the screw. After detecting the holding signal and the return signal of the screw mounting device, the forward / reverse of the motor rotation is judged based on the data, and the motor is started. Then, the quality of the driving condition of the screw is judged by the light type judging device on the positioning device, and if the driving condition is bad, the motor stop signal is outputted and the fact is displayed and an alarm is issued. Manual processing is performed according to the display, resetting is performed and restart is started. If the screw driving condition is good, set the counter to N = N + 1 to move to the next position, arrange the next screw driving system, count the number of driving at the bit, and when the specified number of driving is reached, screw A signal to disconnect the connection of the transport path is output, and a signal to eject the residual screw in the screw transport path is output to remove the residual screw. Then move to the next program step to start driving with another type of driver bit, repeat the work operation according to the flow of the program described above, and when the number of bit types reaches the number of built-in driver bodies or the specified number within it, start bit From the selection preparation operation, the work operation is repeated in the above-described flow to digest the work.

[0047]

Since the present invention is constructed and operates as described above, the following effects can be obtained.

Since various kinds of driver bits can be built in, a wide variety of screws (or screws) can be widely accommodated by this driver main body.

And conventional. In the type that feeds the screw to the tip of the bit outside the body body, the substantial movement distance of the driver bit corresponds to the length of the screw from the complement of the screw to the screwing in, and the screw holding band feeding device is in this gap. Since some of them are located, it may not be possible to hit them at the corners and corners when screwing in, but in the present invention, it is necessary to install and supply screws and screws to the tip of the bit. After doing it inside the body,
It is a type that allows the tubular slide holder to hold the screw when it advances from the main body and holds it while the screw is completely screwed in while the driver bit progresses. In addition, since the sliding holder that holds the screw can be manufactured to be slightly thicker than the bit diameter, it is possible to reach and drive the screw into a narrow and deep part that is impossible with a conventional driver.

Further, since the desired driver can be immediately selected by the switch operation by the electronic circuit and the change of the work contents can be immediately responded to, the work can be smoothly carried out.

Further, since the operation can be performed with one hand, work at a high place is particularly safe.

Since it is an electronic control circuit, it is easy to have other functions. For example, it is easy to add a counter circuit and count the number of screws used, which can be useful for work planning.

Further, since the supply device, the transfer device, the holding mechanism, and the like are mechanisms in which the shape of the tip portion does not matter unless the sizes of the screws are so different, the range of use is further widened.

Further, it is possible to immediately use those in a normal state without purchasing screws or screws already held in the holder band. (This leads to cost reduction and makes it easier to procure materials)

Since the holding effect of the screw is high, the screw can be driven in line with the bit shaft.

By adopting the above-mentioned configuration mechanism, connection with the control system can be easily performed, and an automatic electronic driver having a function capable of exerting a higher effect as a production robot can be obtained.
