Description

[Detailed explanation of the invention] (1) Industrial application field This invention relates to a device for attaching a windmill, which is rotated by pachinko balls, etc., onto the substrate in the manufacturing process of amusement machines such as pachinko machines. be.

(2) Prior Art The above-mentioned wind turbines are installed using a manual method in which a nail is passed through a shaft hole in the center of the wind turbine and an operator drives the nail in with a hammer.

(3) Problems that the invention aims to solve The conventional installation method described above is inefficient because it is done manually, and the nails must be driven vertically and at an appropriate depth so that the windmill rotates lightly. There is a problem in that it requires considerable skill because it requires dedication to the process.

(4) Means for Solving the Problems In order to solve the above problems, the present invention provides a nailer for driving nails into the board on the table above the table on which the board of the game machine is placed. A windmill supply means is provided that automatically supplies windmills having a nail hole in the center one by one between the lower end of the nail receiver member of this nailer and the board, and the lower part of the nail receiver member is closed by a spring. A pair of nail guides are provided at the outer lower portions of both nail guides to guide the nail pushed down by the hammer and to be pushed open by the lower end of the hammer that has descended. Guide pawls are provided to guide both sides of the collar of the windmill supplied from the windmill supply means to position the windmill from side to side, and a stopper is provided at the lower end of the nail receiving member to receive and position the front part of the collar of the windmill, It is equipped with a permanent magnet that attracts and fixes it using magnetic force.

(5) Function Since this device has the above-mentioned configuration, one windmill supplied from the windmill supply means in the standby state of the nailer is connected to the left and right claws at the lower end of the nail receiving member of the nailer and the front part. At the same time as being positioned by the stopper, it is fixed to the lower end of the nail receiver member by a permanent magnet.

Next, the hammer of the nail gun descends, pushes down the nail waiting in the nail receiving member, inserts the nail into the nail hole in the center of the windmill, and drives the lower end of the nail into the board.
It descends further, uses a hammer to spread out the nail guides on both sides against the spring, and descends to attach the windmill that has come off the guide claws to the board.Then, the hammer rises and each part returns to its original position, and the next nail is inserted. It is fed into the nail receiving member, and the next windmill acts to feed the lower part of the nailing member.

(6) Embodiment In FIGS. 1 and 2, A is a nail gun, and B is a windmill supply means.

Nailer A is the same as the known one, consisting of a nail receiving member 3 fixed to a mounting frame 2 provided on a frame 1 so as to be vertically adjustable, and a rod-shaped hammer 5 that is raised and lowered by a driving means 4 such as an air cylinder. It is of structure.

That is, as shown in FIG. 3, there is a vertical guide hole 7 in the nail receiving member 3 through which the hammer 5 passes, and a nail supply hole 8 communicates from diagonally above in the middle part of this hole 7. A pipe 9 leading to a nail supply box (not shown) is connected thereto.

A pair of left and right nail guides 11 are fitted into recesses 10 on both outer sides of the lower part of the nail receiving member 3, and their upper ends are swingably attached to the member 3 via a shaft 12. Reference numeral 13 designates a pair of springs arranged outside both nail guides 11 and having their upper ends fixed to the outside of the member 3;
A piece 14 that contacts the outside of the wind turbine is fixed, and its lower end is used as a guide claw 15 for the wind turbine.

As shown in FIG. 4, a pair of permanent magnets 16 for attracting a wind turbine are embedded in the lower end of the member 3, and a stopper 17 for the wind turbine is provided on the outer side of the member 3. Further, the inner lower portions of both nail guides 11 are made to protrude inwardly, and guide grooves 19 for the nails 18 are vertically provided therein.

Reference numeral 21 in FIGS. 1 and 6 is a guide for the wind turbine supply means B, which is held at a constant downward slope by a bracket 22 fixed to a frame (not shown). The guide 21 has an upwardly U-shaped cross section, and a recess 25 is formed over the entire length of the guide 21 at the top of both sides to receive the flange 24 on the upper outer circumference of the wind turbine 23. cover,
Furthermore, a guide rod 27 supported by a support frame 20 is provided at the upper center of the guide 21 to prevent the wind turbine 23 from floating up.

A support plate 28 is fixed to the side of the guide 21, and the rear end of a drive means 30 such as an air cylinder is attached to the support plate 28 so as to be able to swing up and down about a horizontal shaft 31. A pair of windmill push-out pieces 33 facing downward is provided at the tip of a forward/backward rod 32 that moves forward and backward by this drive means 30.

Further, a pair of left and right springs 34 are provided on both outer sides near the front end of the guide 21 as shown in FIG. 1, and the tips thereof are bent inward to support both sides of the front part of the leading wind turbine 23.

A driving means 35 such as an air cylinder is mounted on the support plate 2 so as to be located at the upper rear part of the driving means 30.
8 and is provided with a cam 36 which is moved forward and backward by this driving means. This cam 36 moves back and forth along the lower side of a guide 37 fixed to the support plate 28 as shown in FIG.
A protrusion 38 fixed to the upper side of the support plate 2 contacts a spring 39 that presses the protrusion 38 against the cam 36.
8 and the front part of the drive means 30.

The windmill 23 is made of a material such as iron that is attracted to a magnet, but if the entire windmill is not made of iron, such as plastic, a plate 40 such as an iron plate that is attracted to a magnet is fixed to the upper surface. Also, windmill 23
The central part of the nail 41 is a tubular part 41, and the lower end thereof has a nail hole 42 into which the nail 18 is loosely fitted.The inner diameter of the tubular part 41 is smaller than the head of the nail 18.

The windmills 23 are lined up inside the guide 21 as shown in FIG. The tips of a pair of extruded pieces 33 are inserted between the parts. Further, a board 44 of a pachinko machine is placed on a table 43 at the bottom of the nailing machine A.

On the other hand, the nails supplied from the tube 9 enter the guide hole 7 through the nail supply hole 8, and are supported on the lower protrusions of a pair of closed nail guides 11 as shown in FIG. In this state, when the driving means 30 works and the advancing/retracting rod 32 moves forward, this pushing piece 33 pushes the leading windmill 23, so that this windmill 23 is moved by the springs 3 on both sides.
4 and move forward, from the tip of the guide 21,
It advances to the lower end of the nail receiving member 3, is positioned by the stopper 17 and the guide pawl 15, and is attracted to the permanent magnet 16, as shown in FIGS. 3 and 7. Further, the second windmill 23 is stopped by the tip of the spring 34.

Under this condition, the driving means 35 operates and the cam 36 shown in FIG. 6 retreats to the position indicated by the chain line in FIG. rotates upward and raises the extrusion piece 33. Under the condition that the push-out piece 33 is raised in this way, the driving means 30 operates to retract the advancing/retracting rod 32 and return to its original position, and the driving means 35 operates to move the cam 36 to the position shown by the solid line in FIG. 38 is pushed down, the push-out piece 33 descends between the first windmill 23 and the next windmill 23, and one stroke of the windmill supply means B ends.

On the other hand, under the condition that the windmill 23 is attracted to the lower end of the nail receiving member 3 as shown in FIG. The means 4 is activated, and the hammer 5 starts to descend, pushing down the upper end of the nail 18, so the nail 18 resists the spring 13 at the lower part of both nail guides 11, pushes the lower part of both nail guides 11 open a little, and descends vertically along the guide groove 19. And windmill 2
The nail 18 passes through the tubular portion 41 of No. 3 and loosely fits into the hole 42 at its lower end, so that the lower end of the nail 18 is inserted into the substrate 44 as shown in FIG.
I'm a little impressed.

The hammer 5 further descends and its lower end touches the nail 18.
As the user continues to press down, the lower end of the hammer 5 inserts itself between both nail guides 11 and descends while pushing them open. Therefore, the piece 14 fixed to the spring 13 also opens, and the guide claw 15 at the lower end of the piece 14 is attached to the flange 24 of the windmill 23.
The windmill 23 comes off and is guided by the nail 18 and descends together with the nail 18. As shown in FIG. 9, when the nail 18 is driven to a predetermined depth, that is, to an extent that allows the rotation of the windmill 23, the hammer 5 stops descending, and then the hammer 5 returns to its original position by the action of the drive means 4. It rises to this position, and the next nail is supplied from the nail supply hole 8.

In this way, under the condition that the hammer 5 has risen to its original position, the windmill supplying means B is activated and supplies one windmill 23 to the lower part of the nailing machine. In this state, move the board 44 on the table 43 so that the desired windmill mounting position is directly below the nailer A, then start the drive means and use the same nailing action as before to place the windmill 23 on the board 44. Mounted in place.

Each condition in the above operation is detected by a position detection sensor such as a limit switch provided on each movable part.

(6) Effect This idea is based on a permanent magnet installed at the bottom of the nail receiving member of a nail gun as described above, and a windmill whose upper part or the entire part is made of ferromagnetic material is attracted to this magnet. Since the nail is driven into the board through the board, the nail is driven into the board very accurately. Therefore, the wind turbine can be installed much more accurately and efficiently than the conventional manual installation of the wind turbine. Further, on the side of the nailer, there is a windmill supply means that arranges windmills with the side with the brim facing upward in a row and supplies them one by one to the bottom of the nailer, and at the bottom of the nailer, There are a pair of left and right guide claws and a stopper for guiding the windmill collar supplied from this supply means and positioning it accurately at the bottom of the nailer.This guide claw can be opened and closed at the bottom of the nailer. It is installed at the bottom of a piece that is crimped by the elasticity of a spring to the outside of a pair of left and right nail guides that are freely attached, so when the pinwheel is pressed down with the nail during nail driving, the hammer will move from side to side. The nail guide is pushed open, and the left and right guide pawls open at the same time, and the lower end of the hammer pushes down the windmill together with the nail, so the windmill descends without being hindered by the guide pawls. Moreover, since the windmill descends using nails that have already been driven into the board as a guide, the windmill can be installed accurately.
