[Detailed Description of the Invention] The present invention relates to an ignition mechanism assembling device for a fuel-filled lighter, which allows an ignition mechanism assembly member to be automatically assembled into a lighter body filled with fuel during mass production of fuel-filled lighters.

The so-called disposable type lighter that is widely used has a well-known structure in which the ignition mechanism assembly member is inserted into the lighter body with a predetermined amount of fuel sealed in the tank. In the assembly process, the assembly was mainly carried out by hand by workers, or partially automated assembly was used.

This idea was created in view of the above-mentioned circumstances.
The ignition mechanism assembly members prepared in advance are separated, and the separated ignition mechanism assembly members are held and conveyed in an upright position to the lighter body which is intermittently conveyed sequentially in an upright position, and the work is carried out by fitting and assembling the ignition mechanism assembly members with the crown. The object of the present invention is to provide a device that incorporates an ignition mechanism for a fuel-filled lighter that can be operated completely automatically and accurately.

Embodiments of the present invention will be described below with reference to the drawings.

The present invention is a device for automatically combining an ignition mechanism assembly member with a lighter body, and includes a separating device A that separates and takes out an ignition mechanism assembly member 4 that has been assembled in advance and is transported from its conveying means, and this separating device. While holding the ignition mechanism assembly member 4 separated and taken out by A, the ignition mechanism assembly member 4 is transported directly above the lighter body 1 that has been sent after being filled with fuel in the previous process. Lighter body 1
It consists of an assembly device B that is integrated into the nozzle, and an adjustment device C that adjusts the nozzle.

In this embodiment, the lighter body 1 is intermittently progressively fed from the previous process along the base 3 by the jig 2 shown in FIGS. 1 and 2 a and b. A predetermined number of lighter bodies 1 are fitted into each jig 2. The separating device A, the incorporating device B, and the nozzle adjusting device C are operated in synchronization with the movement of the jig 2 that is intermittently fed sequentially in this way.

The separation device A is for separating and taking out the ignition mechanism assembly members 4 one by one, which are conveyed by a linear feeder 17 as a conveyance unit connected to a stock portion of the ignition mechanism assembly members 4. It is as follows.

In FIG. 1, a second plate 16 on the opposite side of the first plate 5 of the base 3 is provided for communicating with a stock portion (not shown) of the ignition mechanism assembly member 4 for conveying the ignition mechanism assembly member 4. A linear feeder 17 is arranged as shown in FIG. Two guide bars 18 arranged at right angles to the linear feeder 17 are slidably fitted into bearing members, and one of the guide bars 18 is fitted with an ignition mechanism assembly member. A carrier 20 having a recess 19 for taking in one piece of the bearing member 4 is fixed so as to slide along the outer circumferential axis of the bearing member. A connecting rod 21 is fixed to the ends of the two guide bars 18, and a compression coil spring 22 is wound around the outer periphery of each guide bar 18 between the connecting rod 21 and the bearing member. Connecting rod 21
In addition, the two guide bars 18 are pressed and biased toward the left in FIG. 3, so that the carrier 20 fixed to the guide bars 18 is separated from the open end of the linear feeder 17. Also, the above connecting rod 21
One end of an L-shaped arm 23 that is horizontally movable is connected to. The other end of this L-shaped arm 23 is
It is connected to a second cam follower 25 which is in sliding contact with the outer periphery of the first cam 13 via a link bar 24, and when the cam peak reaches the second cam follower 25 as the shaft of the first cam 13 rotates, the second cam follower 25 The cam follower 25 rotates counterclockwise in FIG. 1, and the L-shaped arm 23 is rotated counterclockwise in FIG. 3 via the link bar 24, connecting the connecting rod 21 and the two guides. The bar 18 is connected to the coil spring 2
2, and is pressed to the right in FIG. As the guide bar 18 moves, the carrier 20 fixed to the guide bar 18 also moves so that its recess 19 coincides with the open end of the linear feeder 17, and the ignition mechanism assembly member 4 for one piece is moved as described above. It is designed to be taken into a recess 19. Furthermore, when the cam crest separates from the second cam follower 25 due to the shaft rotation of the first cam 13, the connecting rod 21 and the two guide bars 18 are moved to the left in FIG. 3 by the biasing force of the wound coil spring 22. Along with this, the carrier 20 also moves to the left in FIG.
The one ignition mechanism assembly member 4 taken into the recess 19 is separated from the other ignition mechanism assembly members 4 in the linear feeder 17. Incidentally, when the carrier 20 moves backward, the open end of the linear feeder 17 is closed by a stopper member of the carrier 20. Further, due to the return movement of the connecting rod 21 and the guide bar 18, the L-shaped arm 23 rotates clockwise in FIG. 3, and the second cam follower 25 rotates clockwise in FIG. 1 via the link bar 24. It is configured to rotate.

Next, the installation device B transports the ignition mechanism assembly member 4, which has been separated and taken into the recess 19 of the carrier 20 by the separation device A, to a position directly above the lighter body 1 while holding it there. It is for press-fitting and assembling into the lighter body 1. This ignition mechanism assembly member 4 is designed to be held between bits 30 shown in FIG. This bit 30 is located at the lowest end of the rod 31. The upper end of this rod 31 passes through the slide holder 28 on the way and is fixed to the slide plate 32, with the tip protruding slightly upward. This slide plate 32 is disposed parallel to the base 3, and has a hole bored through it through which a guide rod 33 erected on the slide holder 28 passes. Also, the plate 3

1 is lowered, and the ignition mechanism assembly member 4, which has been taken into the recess 19 of the carrier 20, is held in place by the bit 30 at the lower end of the rod 31.

Further, after the bit 30 of the rod 31 clamps the ignition mechanism assembly member 4, the link 37 rotates clockwise due to the rotation of the second cam 40, and moves the slide plate 32 to the guide rod 33 via the guide rail 35. Move it up along the rod 3
1. The bit 30 is returned to its upward movement and the ignition mechanism assembly member 4 is taken out from within the recess 19 of the carrier 20.

A slide holder 28 passing through the rod 31 is slidably fitted into a pair of upper and lower guide bars 27. This slide holder 2
A coil spring 29 is installed between the slide holder 8 and the support plate 26, and urges the slide holder 28 so that the rod 31 passing through the slide holder 28 is always positioned on the jig 2 of the base 3. . This slide holder 28 is connected to a fourth cam follower 42 via a pillow ball 41. The lower end of this fourth cam follower 42 is connected to the second cam 4
0, and the third cam follower 39
It is designed to be able to rotate in the same direction. That is,
When the second cam 40 rotates counterclockwise, the fourth cam 40 rotates counterclockwise.
Pulled by the cam follower 42, the slide holder 28 and rod 31 slide to the left in the drawing against the biasing force of the spring 29, and the bit 30 at the lower end of the rod 31 is inserted into the recess 19 of the carrier 20. The rod 3 is located directly above the taken-in ignition mechanism assembly member 4 (the rod 3 shown by the two-dot chain line in Fig. 4).

The slide plate 32 is operated and lowered, and the ignition mechanism assembly member 4 is placed on the upper surface of the lighter body 1 in the jig 2, and the ignition mechanism assembly member 4 is pushed into the lighter body 1 by pressing with a cylinder 43, which will be described later.
After this installation, the second cam 40 returns to its upward movement again.

Further, above the support plate 26, a cylinder 43 is arranged on the axis of the rod 31, so that the upper end of the rod 31 can be pressed downward.

Furthermore, the micro switch 44 is connected to the guide bar 27.
The pusher bars 45 are fixed to the ends of the slide plates 32, respectively, so that an operation completion signal as described below can be detected.

On the other hand, the nozzle adjustment device C is installed in the lighter body 1 in the built-in device B as shown in FIGS. 1 and 2.
In order to adjust the nozzle adjustment member 10 of the ignition mechanism assembly member 4 incorporated in the ignition mechanism assembly member 4, an abutting member 11 that moves toward and away from the slightly protruding outer surface of the nozzle adjustment member 10 to come into contact with and separate from the nozzle adjustment member 10 is provided. This contact member 1
1 is fixed to a slide core 8 which is slidably fitted into the guide bar 7. This guide bar 7 is mounted between a pair of guide plates 6, 6 that are perpendicular to the guide bar 7, and a tension rod mounted between this guide plate 6 and the slide core 8. A spring 9 urges the slide core 8 toward the base 3.

The guide plate 6 is provided along the direction of movement of the jig 2, and is connected to a first plate connected to the base 3.
It is erected on the plate 5. Further, one end of a crank arm 12 abuts against the distal end surface of the slide core 8. A central portion of the crank arm 12 is rotatably attached to the first plate 5. Moreover, the other end of the crank arm 12 is
It is connected via a pillow ball 15 to an L-shaped first cam follower 14 that slides on the outer periphery of the first cam 13, and is responsive to the pressure of the crank arm 12 due to the shaft rotation of the first cam 13 and the tensile force of the tension spring 9. Therefore, the slide core 8 moves reciprocally, and the nozzle adjustment member 10 is brought into contact with the contact member 11 of the slide core 8, thereby causing the nozzle adjustment member 10 to rotate. The first cam 13 is
It has a predetermined shape that causes the L-shaped first cam follower 14 to swing, and is rotated by a drive motor (not shown).

Next, the operation of the present invention will be explained.

First, the standby states of the separating device A, the incorporating device B, and the nozzle adjusting device C are as follows:

The separating device A is configured such that the connecting rod 21 and the two guide bars 18 are moved to the third position by the urging force of the coil spring 22.
Return to the left direction in the figure and remove the concave part 1 of the carrier 20.
Reference numeral 9 is in a standby state in which it is separated from the open end of the linear feeder 17 with one ignition mechanism assembly member 4 installed therein.

The built-in device B is configured to rotate the fourth cam 40 by rotating the second cam 40.
The cam follower 42 rotates counterclockwise and the slide holder 28 moves to the left in FIG. is located directly above the position where it slides away from the linear feeder 17.

In the nozzle adjustment device C, the first cam follower 14 is rotated counterclockwise, and the crank arm 12 pushes the slide core 8 to the right in FIG. 1 while resisting the tensile force of the tension spring 9. In this state, the contact member 11 is retracted from above the jig 2.

Next, the separating device A and the incorporating device B operate as follows.

First, when the second cam 40 rotates and the third cam follower 39 rotates counterclockwise in FIG. 4, the operating rod 36 moves to the left in FIG. 4, and the pair of links 37 rotate counterclockwise. As a result, the slide plate 32 and the rod 31 are lowered to remove the recess 1 of the carrier 20.
The ignition mechanism assembly member 4 in 9 is held between bits 30. The bit 30 and rod 31 holding the ignition mechanism assembly member 4 therebetween are returned to the upper position by the rotation of the second cam 40, and the ignition mechanism assembly member 4 is taken out from the recess 19 of the carrier 20.

Next, the fourth cam follower 42 returns clockwise to move the slide holder 28 to the right in FIG.
When positioned above, the third cam follower 39 rotates counterclockwise again due to the rotation of the second cam 40, and slides the operating rod 36 to the left in FIG.
The link 37, the guide rail 35, and the slide plate 32 are operated to move down, and the ignition mechanism assembly member 4 is placed on the upper surface of the lighter body 1 in the jig 2. Then, for example, a detection device (not shown) outputs a position detection signal for the bit 30 and the cylinder 43
is operated to press the upper end of the rod 31 downward in FIG. 4, and the ignition mechanism assembly member 4 is press-fitted into the lighter body 1.

At this time, the push bar 45 presses the micro switch 44 to obtain an assembly completion signal, and at the same time as the cylinder 43 returns, the third cam follower 39 rotates clockwise to move the guide rail 35 to the second position. In order to move upward in FIG. 4, the bit 30 separates from the ignition mechanism assembly member 4 that was being held and is lifted upward, and the fourth cam follower 42 rotates counterclockwise to move the slide holder 28. moves to the left in FIG. 4, and the bit 30 returns to the waiting position.

On the other hand, when the ignition mechanism assembly member 4 taken into the recess 19 of the carrier 20 is pinched and taken out by the bit 30 of the installation device B, the first cam 1
By the rotation of step 3, the cam mountain becomes the second cam follower 25.
The second cam follower 25 rotates counterclockwise in FIG. 1, and the L-shaped arm 23 rotates counterclockwise in FIG. The book guide bar 18 is moved to the linear feeder 17 against the biasing force of the coil spring 22.
direction, the recess 19 of the carrier 20 is aligned with the open end of the linear feeder 17, and one ignition mechanism assembly member 4 is taken into the recess 19. Thereafter, when the cam crest separates from the second cam follower 25 due to the rotation of the first cam 13, the connecting rod 21 and the two guide bars 18 return to the left in FIG. 3 due to the biasing force of the coil spring 22. The carrier 20 also moves to the left and separates from the open end of the linear feeder 17, entering the above-mentioned waiting state.

Next, the nozzle adjustment device C operates as follows. The nozzle adjustment by this nozzle adjustment device C is as follows:
This is the next step after the step of assembling the ignition mechanism assembly member 4 into the lighter body 1 in the assembling device B, and is, for example, setting the nozzle adjustment member 10 to the maximum open (+) side.

When the lighter body 1 is moved intermittently along the base 3 from the built-in device B position to the nozzle adjustment device C position, the first cam follower 14 rotates clockwise, pushes the pillow ball 15, and moves the crank arm. 12 is rotated counterclockwise to release the contact with the slide core 8, the slide core 8 slides to the left in FIG. The nozzle adjusting member 10 has a tip end slightly protruding from the lighter body 1, and the member 10 is attached to the outer surface of the nozzle adjusting member 10.
Contact and press from the side opposite to the direction of adjustment movement. The nozzle adjustment member 10 is rotated by the amount of movement of the contact member 11 to set it to a predetermined setting state, for example, to the maximum open (+) side. Then, when the first cam follower 14 returns counterclockwise,
The crank arm 12 rotates clockwise, the slide core 8 slides to the right in FIG. 1 against the tensile force of the spring 9, and the abutment member 11 retreats from the nozzle adjustment member 10, resulting in a standby state. becomes.

As mentioned above, the present invention solves the complicated task of assembling the ignition mechanism assembly members, which are separated one by one from the stock part, into the lighter body in a jig that is continuously and intermittently fed onto the base. Since it is designed to be carried out continuously and automatically, the work efficiency is extremely high.
Moreover, it is accurate, has a high yield, is extremely effective in terms of quality control, and has the effect of making it possible to manufacture lightweight lighters at low cost.
