Abstract

PROBLEM TO BE SOLVED: To stop swinging of a support easily and surely by providing a stopper capable of touching the support and a support pressing means in the support side shaft supported freely by a device body. SOLUTION: When moving a movable body 26 to the front (front direction of paper), the pinch roller 28 provided on the movable body 26 moves to the front and leaves from the guide face 18 of a pressing means, a rod 14, and the pressing part 17 of the tip end leaves from the support 9 side so that the support 9 becomes capable of swinging. When the movable body 26 moves to the front, a button 7a of a switch 7 moves to the front to turn on the switch 7 and so a laser light emission device becomes usable. On the contrary, when the movable body 26 is moved to the back, the pinch roller 28 moves to the rod 14 direction to press the guide face 18 so that the rod 14 rotates to press the side of the support 9 with the pressing part 17 and moves to the opposite direction to the rod 14. By this, the support 9 touches the stopper, casing inner wall and its swing is stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swing-stopping mechanism, and more particularly to a swing-stopping mechanism capable of restraining a swinging motion of a pendulum swinging support relative to an apparatus body. This is used for a laser device for ink marking.

[0002]

2. Description of the Related Art Heretofore, this kind of rocking stop mechanism basically has a structure in which a support on which a laser light emitting device for projecting laser light is mounted is rotatably supported in a vertical plane. It is generally used for a pendulum swing type ink-marking laser device described above.

[0003] The above-described blackout laser device is shown in FIG.
As shown in (b), a support 43 formed of a solid bar is disposed at the center of the circular shape of a horizontal frame 42 fixed horizontally to two columns 41, 41 erected from the bottom of the apparatus body 40, After the pivot shaft 45 is inserted into the inner diameter of the bearing 44 fitted in the through hole formed in the support 43, the pivot shaft 45 is connected to the horizontal frame 42.
And a laser light emitting device 46 is attached to the upper end of the support 43.

Therefore, in the above-described ink-marking laser device, since the support 43 is rotatable about the pivot shaft 45, the device body 40 of the ink-marking laser device is mounted on an inclined place. Even if it is placed, the support body 43 is always in a vertical state due to its own weight.

[0005] The swing-stopping mechanism, which is employed in the above-described ink-marking laser device and is intended to stop the swing of the support member 43 during movement or when not in use, is provided with an extended bifurcated locking mechanism. The body 47 is pivotally supported by an inverted concave support plate 48 on the lower surface of the horizontal frame 42, and is rotatable in a direction orthogonal to the swing direction of the support 43. By pivoting, the fork bilaterally surrounds the support 43, locks the support 43, and can suppress the swing of the support 43.

[0006]

However, in the above-mentioned rocking stop mechanism, the interval E between the forks of the locking member 47 is formed to be larger than the width F of the support 43, so that Since a gap is formed between E and the width F, there is a problem that it is impossible to completely stop the swing of the support 43.

In order to solve the above problem, the distance E
It is conceivable to make the gap between the support 43 and the horizontal frame 42 as small as possible.
Are not maintained in the orthogonal state, that is, the device body
When the locking member 47 is rotated in a state in which the locking member 47 is not in the vertical state, one of the two forks of the locking member 47 interferes with the support 43, and the locking member 47 is rotated.
Further rotation of 47 is impeded and support 43 is
It becomes impossible to lock 43. Therefore, in the above-described swing stop mechanism, in order to securely lock the support, the locking body 47 is maintained in a state where the apparatus main body 40 is maintained in a substantially vertical state.
It was necessary to perform a very complicated operation of rotating the.

In view of the above, the present invention has been made in view of the above-described conventional problems, and it is possible to reliably prevent the swing of the support that swings with the pendulum with respect to the apparatus main body, and to prevent the swing of the support. An object of the present invention is to provide a rocking stop mechanism such as a laser device for marking out, which can be very easily performed to stop the rocking.

And characterized by the following.

In the swing-stopping mechanism such as the blackout laser device having the above structure, the pressing means presses the support 9 so that the support 9 swings while being pressed by the pressing means. Contact 1 Accordingly, the support 9 is fixedly held between the locking body 1 and the pressing means, and the swing of the support 9 is restrained. On the other hand, when the pressing means is separated from the support 9, the support 9 is also separated from the locking member 1, so that the support 9 can swing.

According to a second aspect of the present invention, there is provided a swing stop mechanism for a blackout laser device or the like, wherein the pressing means is a rod 14 rotatably supported by the apparatus main body 2. In addition, the rod 14 is formed with a guide surface 18 inclined with respect to the rotation surface of the rod 14.
When the movable contact body 28 abuts in a direction substantially orthogonal to the rotation surface of the rod 14, the rod 14 rotates, and the pressing portion 17 at the tip of the rod 14
9 can be adopted.

According to a second aspect of the present invention, there is provided a rocking stop mechanism for a blackout laser device or the like in which the pressing portion at the tip of the rod presses the support when the rod rotates. The support 9 swings while being pressed by the pressing means, and comes into contact with the locking body 1. Therefore, the support 9 is composed of the locking body 1 and the rod 14
The pressing member 17 is pinched and fixed, and the swing of the support 9 is stopped. Moreover, when rotating the rod 14, the movable contact body 28 is moved in a direction substantially perpendicular to the rotation surface of the rod 14, and the contact body 28 is pressed against the guide surface 18 and pressed. Then, the pressing force of the contact body 28 against the guide surface 18 is componentized, and a part thereof acts in a direction for rotating the rod 14.

On the other hand, when the rod 14 rotates in a direction opposite to the above direction, the pressing portion 17 is separated from the support 9 and the support 9 is separated from the locking member 1. Becomes swingable. Moreover, when rotating the rod 14 in a direction opposite to the above direction, the contact body 28 is moved to separate the contact body 28 from the guide surface 18. Then, the rod
The component force acting in the direction of rotating 14 disappears, and the restrained state of the support 9 is released.

The rod 14 is inserted into a hole 2c formed in a side position of the hole 2b and then fixed from the back surface of the support piece 2a with a nut 16, so that the rod 14 is pivotally supported with respect to the apparatus main body 2. At the same time, the support member 9 rotates on a surface parallel to the swinging surface of the support member 9 (the rotation surface of the rod 14).

The rod 14 is arranged on one side with respect to the hole 14a.
14b is formed to be longer than the other side 14c, and the tip of the one side 14b abuts on the side surface of the support 9 (the surface of the support 9 on the side in the swinging direction is the side, the same applies hereinafter). Possible pressing parts
17 are formed. Therefore, when the rod 14 rotates, the pressing portion 17 can freely contact and separate from the side surface of the support 9. still,
The position where the pressing portion 17 contacts the side surface of the support 9 is near the side of the mounting hole 11 for mounting the laser light emitting device 30.

The other side 14c of the rod 14 has a pivot shaft.
A guide surface 18 that is inclined with respect to 15 is formed. Specifically, the guide surface 18 has an angle of about 45 degrees with respect to the pivot 15, but is not limited thereto. More preferably, it should be at least about 30 degrees, and should be within about 80 degrees, and more preferably be within about 60 degrees.

The movable body 26 is made of, for example, an iron plate, and is movable in engagement with the protruding piece 7a of the switch 7 which is movable in the front-rear direction, that is, in the direction orthogonal to the swinging surface of the support 9. is there.
That is, the movable body 26 also has a movable range of about 3.3 mm like the protruding piece 7a.

In front of the movable body 26, a holding portion 27 having a substantially U-shape in a front view is formed by appropriately bending an iron plate strip, and a pinch roller 28 as a contact body is formed.
Are accommodated in the holding portion 27, and are rotatably supported by a shaft 29 fixed to the holding portion 27 in the vertical direction. Moreover, since the shaft 29 is provided near the edge of the holding portion 27, when the pinch roller 28 is supported by the shaft 29, a part of the pinch roller 28 is exposed from the holding portion 27. State.

When the movable body 26 is attached to the apparatus main body 2, that is, when the movable body 26 is
When the pinch roller 28 is engaged with the guide surface 7a,
It is formed at a position where it can come into contact with 18.

Therefore, when the movable body 26 is moved in the Q direction, the protruding piece 7a engaged with the movable body 26 also moves to the rearmost end (position Q), and the circuit is closed, so that the laser beam Light emitting device 30
When the supply of electric current to the
When the movable body 26 is moved in the P direction, the protruding piece 7a also moves to the forefront end (position P), and the circuit is in a conductive state. The current is supplied to the device 30, and the pinch roller 28 is separated from the guide surface 18 of the rod 14.

The ink-marking laser device employing the rocking suppression mechanism according to the present embodiment has the above-described configuration, and switches between a state in which the support 9 can rock and a state in which the rocking operation of the support 9 is stopped. An operation mode will be described. FIG.
As shown in (a) and (b), the movable body 26 is moved to the position P by moving it forward.

In this state, since the pinch roller 28 provided on the movable body 26 moves forward, the pinch roller 28 is separated from the guide surface 18 of the rod 14. Accordingly, since the rod 14 is in a rotatable state and the pressing portion 17 at the tip of the rod 14 is separated from the side surface of the support 9, the support 9 is in a swingable state.

Further, when the movable body 26 is moved to the position P, the protruding piece 7a of the switch 7 also moves forward,
Is turned on, electricity is supplied from the power supply to the laser light emitting device, and the laser light emitting device emits laser light,
This is a state in which the blackout laser device can be used.

Next, as shown in FIGS. 4A and 4B, when the use of the blackout laser device is stopped or when the blackout laser device is transported, the movable body 26 is moved backward. To change the position to the position Q.

At this time, a pinch roller 28 provided on the movable body 26 moves in the direction of the rod 14 and comes into contact with the guide surface 18 of the rod 14, and further presses the guide surface 18. Then, the pressing force of the pinch roller 28 is divided by the guide surface 18, and the force is urged in a direction orthogonal to the pressing force, that is, in a direction for rotating the rod 14. Then, as the rod 14 rotates, the pressing portion 17 at the tip of the rod 14 comes into contact with and presses against the side surface of the support 9, and the support 9 is pressed.
Is swung in the opposite direction to the rod 14. Therefore, the support 9 is
14 comes into contact with the inner wall of the casing 2 in the opposite direction, and the support 9 is sandwiched and fixed by the pressing portion 17 of the rod 14 and the casing 2 as a locking body. Swing is stopped.

Further, when the position of the locking member 27 is changed to the position Q, the protruding piece 7a of the switch 7 also moves backward,
Is turned off, the supply of electricity from the power supply to the laser light emitting device stops, the laser light emitting device emits no laser light, and the blackout laser device becomes unusable.

As described above, in the ink jetting laser apparatus employing the swing stop mechanism according to the present embodiment, the movable body
It is possible to switch the supporting member 9 between the swinging and non-swinging states only by moving the back and forth 26, and to turn on and off the power of the blackout laser device.

Further, the swing restraining mechanism according to the present embodiment includes a pinch roller 28 serving as an abutting member.
By moving the movable body 26 in the front-rear direction into the left-right movement of the rod 14 by contacting the guide surface 18 inclined with respect to the moving direction of the This is a mechanism for stopping, that is, a mechanism for stopping the swing of the support 9 by a movement in a direction different from the swing direction of the support 9,
For example, when the swing direction of the support 9 cannot be widened due to a design problem, the swing restraining mechanism has an excellent advantage.

Further, the support 14
9 is formed longer than the distance from the hole 14a to the guide surface 18 which contacts the pinch roller 28, the amount of movement of the pressing portion 17 is 28 movement amounts, for example, about 3.
It has the advantage of being amplified and larger than 3 mm. Therefore, the moving amount of the pressing portion 17 is increased even by a slight moving amount of the movable body 26, so that the pressing portion 17
Has the advantage that it can be reliably pressed to a position where it contacts the inner wall of the casing 2 and the support 9 can be fixed securely.

The pinch roller 28 as the contact body is
Since it is rotatably supported by the shaft 29 on the holding portion 27 of the movable body 26, when it comes into contact with and presses the guide surface 18 of the rod 14,
The pinch roller 28 is in a state of rolling on the guide surface 18, and has an advantage that the pressing force of the pinch roller 28 can be smoothly transmitted to the guide surface 18.

In addition, the swing-stopping mechanism according to the present embodiment is a mechanism that stops the swing of the support 9 by the pressing portion 17 pressing the support 9 from the side of the support 9. Whatever state the support 9 is in with respect to the device body 2,
The swing of the support 9 can be easily and reliably stopped, and therefore, it is necessary to perform a very complicated operation of keeping the main body of the apparatus substantially vertical as in the conventional swing stop mechanism. It also has the advantage of disappearing.

Further, by changing the position of the movable body 26,
Since the power supply to the laser light emitting device can be turned on and off, only by changing the position of the movable body 26, the support 9 can be switched between the swingable state and the swing-stopped state, and the switch 7 can be switched.
Has the advantage that the operation can be greatly simplified.

The present invention is not limited to the above-described embodiment, but can be appropriately designed and changed. That is, in the present embodiment, the case where the rocking suppression mechanism is adopted in the laser device for blackout has been described, but the present invention is not limited to this.
It can be applied to a device having a configuration in which the support 9 swings in a pendulum, for example, an optical device, a seismometer, a balance, a pendulum clock, and the like.

In the above-described embodiment, the rod 14 is employed as the pressing means. However, the present invention is not limited to this, and a cam such as a plate cam may be employed.

Further, in the above embodiment, the inner wall of the casing 1 of the blackout laser device is used as the locking member that can be brought into contact with the support member 9; A body may be provided, for example, attached to the apparatus main body 2.

Further, a pinch roller 28 is employed as an abutting member that abuts on the guide surface 18 of the rod 14. However, the present invention is not limited to this, and a part of the movable body 26 directly abuts on the guide surface 18. In this case, the movable body 26 has a function as a contact.

Further, since the rod 14 is formed to be lighter in weight than the support 9, when the support 9 is made to be able to swing, in particular, the pressing portion 17 of the rod 14 is forcibly pressed. Support 9
It is not necessary to separate from the side surface of the support member 9, but the present invention is not limited to this, and a configuration in which a force of an elastic body or the like is urged in a direction in which the pressing portion 17 of the rod 14 separates from the support body 9 can be adopted.

[0054]

As described above, the swing-stopping mechanism such as the blackout laser device according to the present invention comprises a locking member provided on the side of a swingable support, Since the pressing means is used to maintain the contact state of the support, the support can be reliably fixed by the locking body and the pressing means only by pressing the support with the pressing means.

Further, the swing-stopping mechanism such as the blackout laser device according to the present invention is configured such that the support swings while being pressed by the pressing means, and comes into contact with the locking member, thereby stopping the swing. Therefore, regardless of the state of the support with respect to the apparatus main body, the support can be securely fixed, and
In stopping the swing of the support, it can be performed very easily.

Further, according to a second aspect of the present invention, there is provided a swing stop mechanism such as a blackout laser apparatus, wherein the pressing means comprises:
A rod rotatably supported by the apparatus main body, and the rod includes:
A guide surface that is inclined with respect to the rotation surface of the rod is formed, and the movable surface of the rod abuts on the guide surface in a direction substantially orthogonal to the rotation surface of the rod. Since the pressing portion at the distal end presses the support, the swing of the support can be reliably suppressed only by rotating the rod.

Further, when the swing of the support is restrained, the rod for fixing the support is performed by the contact of the contact body, so that the rod is moved by a very simple operation of only moving the contact body. The practical value is significant in that the swing of the support can be suppressed.

In addition, since the guide surface is inclined with respect to the rotation surface of the rod, when the rod is rotated, the movement of the abutment should be different from the rotation direction of the rod. So that the contact body can be moved in the swinging direction of the support,
It is not necessary to provide the support in the rotation direction of the rod, and the above problem can be avoided even if the width of the swing direction of the support is limited due to the design problem of the target device.
