機とすることができたのである。In order to eliminate the drawbacks of the conventional continuous screw dispensing machine, the present invention provides the following:
Equipped with a mechanism that sequentially sends each screw of the screw connection emperor to the Hr fixed position of itself while repeating the operation of protruding a certain distance forward from the electric motor part and retreating from the protruding position in the direction of the turtle motor part. The part of the front end of the block that is applied to the workpiece for screwing is y.
At the center is a pressing plate of the screw connecting band whose front edge slightly protrudes from the front end of the block. The holding plate is biased by an elastic spring provided between it and the block, and when the holding plate is retracted into the block against the elastic Irf spring acting on it, each piece of the holding plate This is a flaw or sign that the edge of the screw collides with the screw connecting band and causes the connecting band to follow the rear of the block. V because it is being pulled towards
Utilizing the action of the front end of the block being exposed to the workpiece before screwing the screw into the workpiece, which creates an inclined axis with respect to the LL bit axis, the presser plate protruding from the front end of the block is first inserted into the block. At the end of the push-in, the rear edge of the plate η1 hits the screw connecting band and pushes the connecting band towards the rear of the block.In this way, the screw can be pushed inside the block only by pushing up the connecting band. Since the tendency of the tilting force F is eliminated, the tendency of the screw screwed into the workpiece to tilt is almost eliminated, and an excellent continuous screw tightening machine that can perform the screwing operation easily can be achieved.

す。The screw connecting band 41, which is fed while sliding on the window frame forming the window hole 39, that is, on the block 61, has screws S attached at regular intervals, so that when the tip of the feed pawl 50 swings inside the window hole 69, , corresponds to the next screw. However, in this case, the tip of the feed claw 5° resists the spring force 54 and easily rotates counterclockwise around the stop @53 as a fulcrum, and the tip of the screw 1.
You can get through it. Therefore, when the screw passes through in this manner, the feed pawl 50 immediately returns to the upright state by the spring 54, and when the feed lever 33 returns to the position shown in FIG. 5, it hits the midsection of the screw that has just passed through.
The screw is sent to the center of the block 31. In this way, the screw connection band 41 is fed one pitch at a time each time one of several screws S is plated on the wood BKNi, and the screws S on the connection band 41 are sent out one by one to a predetermined position on the block 31.

への組込みができるようにしである。A screw holding pawl 66 is attached to the side of the block 31 with a screw #167 to prevent the screw connection @41 incorporated into the block 31 from moving unnecessarily in a predetermined position. (4th
(See figure) The pawl 66 is designed to hold the belly surface of the screw on the same side as the screw feed pawl 50 at a position before and after the screw feed pawl 50, and has an angle that protrudes from the side of the block 31 over the screw S. A small projection protrudes from the lower surface of the rod 68. However, since the screw connecting band 61 cannot be assembled into the block 31 with this retaining claw 66, the screw connecting band 61 cannot be assembled into the block 31. A spring 70 is installed between the metal 69 and the elastic force of the spring 70 is applied to the square bar 68.
This makes it effective in suppressing Bis S, and
Against the spring cuff 0, the square bar 68 rotates around its upper shaft 67 so as to rise slightly, and the holding claw 66 opens the screw holding position, thus allowing the screw S to be installed in a predetermined position. That's how it is.

When pushed out, the bit 20 pushes up the screw holding pawl 66 against its spring cuff 0 so that it does not become an obstacle when the bit 20 passes under the holding pawl 66. Further, when the feeding claw 50 feeds out the next screw, the delivered screw S pushes the holding claw 66 with its abdomen, thereby allowing the screw S to be seated at a predetermined position. Therefore, the end surface of the holding claw 66 on the screw feeding side is an inclined surface that is easily pushed up by the abdomen of the screw.

ある。In order to tighten the screw S to the wood B, hold the handle 10 of the tightening machine and apply the tip of the tightening machine to the wood B as shown in FIG.
A pressing plate 71 protruding from the front surface of the block moves into and out of a cutting groove 72 on the front surface of the block. Although this holding plate 71 is thin, it is prevented from falling out of the cut groove 72 by the ω plate 73 attached to the back side of the block 61 and the stopper 69 of the front polish holding claw 66 as shown in FIG. However, in order to allow the front edge to protrude a small length from the front edge of the block 61 at that time, there is a repellent spring 74 between the block 61 and the part that wraps around the back side of the block 31. is assembled and urged to protrude by the spring 74.However, in order to restrict the protrusion length, a stop end 73' is provided protruding from the cover plate 73 attached to the back side of the block 31, Said 1 pregnant toe 7
The stepped portion 71' of the holding plate 71 is arranged to abut against the holding plate 61.

る。When the tightening machine presses against the wood B, the presser plate 71 is retracted into the block 31 so that the front edge of the presser plate 71 is flush with the front edge of the block filter 1 as shown in FIG. At this time, the dirt green 75 on the block 61 of the holding plate 71 hits the synthetic resin band 41 of the screw connection band 41 passing through the back thereof, and pushes up the band 41 slightly to the rear of the block 31.

裁が悪い。By the way, when the screw connecting band 41 is pulled out from the container 4 and assembled into the block 31, the screw connecting band 41 is pulled diagonally to the rear of the block 61 due to the positional relationship between the container 4 and the block filter 1 as shown in FIG. This tendency causes the screw S, at a predetermined position on the block 31, to be slightly inclined with respect to the block center line. Therefore, if the screw S is screwed into the wood B with the pin 20 in the same state, the screw S will be screwed into the wood B in an apparently slanted state and will pierce the iron plate A. This not only requires a very large driving force to screw in, but also reduces the binding force of the wood B to the iron plate A, and the shape of the screws that appear on the wood B is also unsightly.

定方向への送り出しを許容する。When the tightening machine is pulled away from the wood B, the presser plate 71 immediately protrudes a predetermined length by the spring 74, releasing the pushing force on the screw connection band 41, so that the connection band 41 is moved in a predetermined direction by the block 31-hi. Allow sending out.

が与えられる。その機構は次のとおりである。When the tightening machine is pressed against the wood B to tighten the screws, the block filter 1 and the supporting vibro 0 move into the electric motor section 1.
The bit 20, which protrudes a certain length from the screw 100, hits the countersunk head of the screw S on the block 31. When the tightening machine is pressed further, the block 61 retreats further onto the motor part 1, and the bit 20 breaks the connection of the screw S with the connecting band 41 and pushes out the top of the block 31 without piercing the wood B. Bit 20 in Komata
A rearward thrust is also generated, and rotational force is applied to the bit 20 for the first time. The mechanism is as follows.
ビット20は第8図に児られるように、それを組込んだ

The female clutch 25 formed at the rear end of the bit rotating shaft 22 is extended forward until it abuts against the bearing 80 by a spring 24 (dotted line diagram in Figure 8) incorporated between 25 is separated from the corresponding male clutch 82 at the front end of the transmission shaft 81. Then, when a backward thrust is generated on the bit 20 as described above, the bit rotation axis 22
slides backward against the spring 24, where the female clutch 25
engages with the male clutch 82 at the front end of the transmission shaft 81, and the bit rotates! 22 rotates. That is, the bit 20 rotates and the screw S

Therefore, the tip is made of a hard material. However, if you tighten a large number of screws S, the tip will be rounded with a sharp tooth 1.Therefore, the bit 2
0 from the bit rotation axis tkb 22 (((remove and replace with a new one).
) The tip protrudes from the front of the no-using 100, and the protruding part is provided with a square hole 23 into which the square shaft 20' of the focus 200 can be inserted, and then the rear end of the square shaft 20' (the rear 4A is also used with a bit and no screw). Insert the raw ball 27 (shown in Figure 8) that falls into the groove 26 formed in the rear part of the bit corner shaft 20'' into the small hole 28 made in the bit rotation shaft 22,
The bit angle shaft 20' is prevented from being pulled out from the bit rotation shaft 22 by a steel ball 27 that fits into the groove 26 and the small hole 28, and the sleeve 21 is attached to the bit rotation +t'ji 22. to prevent the steel ball 27 from protruding from the small hole 28, but the groove 29 formed on the inner surface of the front end of the sleeve 21 can be removed by retracting the sleeve 21.
8, the steel ball 27 can partially penetrate into the groove 29, so when the bit angle shaft 201 is pulled out from the bit rotating shaft 22, the groove 26 of the angle axis 2σ will be aligned with its slope. Push the steel ball 27 upwards into the small hole 28 and release the engagement between the square shaft 201 and the bit rotation shaft 22, and the square shaft 20' can be pulled out from the square hole 26.

浅くなる。When tightening the screw S into the wood B, it may be necessary to adjust the shallowness and depth of the tightening. In order to be able to make minute adjustments, the vibro 0 is inserted into one of the pipes 30 and 50 supporting the block 61, as shown in FIG.
3, and moves the position of the receiving plate 14 after i%jl where it collides with the receiving plate 14 provided at the rear end of the hole 1.50 and stops moving back. A push ring 86 is provided with a part of its circumferential surface exposed to the surface of the housing 100, and the press ring 86 has a knurled cut on its circumferential surface to facilitate rotation operation with a fingertip. The press ring 8
6 is rotated, the receiving plate 14 combined with the female thread provided on the thin knitting 86 slides on the square shaft 87 and changes its position. When the receiving plate 14 is in the front part of the square cap 87, the pipe 30
is in its retreated position or rather shallow. Therefore, since the block 61 is in the retracted position, the bit 20 is located at the rear of the block 31 by that amount, and the tightening of the screw S is difficult.
It becomes shallow.

゜[Scope of Claims] A block in which a screw connecting band, in which a large number of steel screws are attached at regular intervals using easily broken threads, is inserted in a predetermined position is protruded from the front end of the electric motor section, and is driven by the electric motor section. The block is provided in the motor housing so as to be biased so as to always protrude a certain length in front of the rotating bit. When one of the screws is applied to the workpiece in order to screw into the mJ object and the electric motor section is pushed closer to the workpiece, the block resists the biasing force acting on it and approaches the electric @ section housing. giving an initial motion to the screw connecting mechanism, and on the other hand, the bit engages with the head of the first screw in the screw connecting band in the block, transmitting rotation to the screw, and screwing the screw into the workpiece; At the time when the screwing is completed, when the pushing action of the electric motor part towards the workpiece is released and the electric motor part is pulled away from the workpiece, the block protrudes back to its predetermined position due to the biasing force acting on it, In the continuous screw tightening +i machine, in which the screw connecting band feeding mechanism provided on the block carries the screw and sends out the next screw in the four bands to the front of the bit by the protruding return operation, the front end of the block is at the center y, The front edge of the screw connecting band should be made to protrude slightly from the front end.The presser plate of the screw connecting band is biased by an elastic spring provided between the presser plate and the block so that the front edge of the presser plate always projects from the front end of the block. The retaining plate is retracted inward of the block against the elastic force acting on it, and the rear edge of the retaining plate collides with the screw connecting band, causing the connecting band to also retreat to the rear of the block.
