Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a rotor for a rotary stamp using an endless belt stamp.

(Prior Art) Conventionally, a U-shaped frame has a bridging piece at the tip, and a fixed shaft is installed between the intermediate parts of the frame, and a plurality of drive rotors are rotatably provided around the fixed shaft. A rotary rubber stamp, which is rotatably supported in parallel with each other, is provided with an endless belt stamp made of a rubber material between each belt hooking section and the bridging piece, if one rotor is rotated. One fixed endless belt mark was always rotating.

Therefore, there is a need for a rotor that operates as many endless band marks as there are endless band marks.

Further, in the rotor that operates the endless band mark, the disk on which the force is applied needs to have a certain thickness, so that there is a gap between the endless band marks.

Further, it is necessary to use the above-mentioned disc that has a diameter larger than the outer diameter of the endless belt mark that is axially supported by the fixed shaft and that is stretched on the belt hanging cylinder portion. Becomes complicated and large, and the cost is high.

In addition, in order to solve the problem of the appearance shape for the purpose of improvement, there are JP-B-55-18210, JP-B-55-18211, and JP-A-51-119812, which include a drive rotor and an endless belt. The number of marks is the same, which is not effective in the present invention.

(Problems to be solved by the invention) As described above, conventional rotary rubber stamps with stretched endless belt marks require the same number of endless belt stamps and rotors, resulting in high cost, complicated appearance and large size. There is a point.

Therefore, one rotor rotates two endless belt marks,
(EN) Provided is a rotor for a rotary mark, in which the distance between the endless belt stamps is small, the appearance is neat, the mold is easy to mold, and the assembly is easy.

(Means for Solving the Problem) A shaft cylinder 6 is stretched around the center of the drive rotor 4, and two sets of a locking end 8 and an arc-shaped lubricating arc 9 are provided on the outer peripheral surface of the shaft cylinder 6. With respect to the locking claws 7, one set of the locking claws 7 is directed outward from the center of the barrel 6 in a fixed rotation direction, and the other set of the locking claws 7 is the above-mentioned one.
The locking teeth are provided in the direction opposite to the set from the center of the shaft cylinder 6 toward the outside in a certain rotation direction, and abut on the lubricating arcs 9 of the two sets of the locking pawls 7 so as to mesh with the locking ends 8. The rotor for rotary marking is characterized in that two interlocking rotors (10) each having an inner wall (13) of a belt hanging cylinder portion (12) are provided so as to cover the two sets of locking claws (7).

(Operation) On the outer peripheral surface of the shaft cylinder 6 stretched around the center of the drive rotor 4,
Two sets of locking claws 7 each of which includes a locking end 8 and an arc-shaped lubricating arc 9 which are provided from the center of the shaft cylinder 6 toward the outside in a fixed rotation direction have opposite rotation directions. Is provided so as to contact the lubrication arc 9 on the inner wall of the band-hanging tubular portion 12,
Two interlocking rotors provided with locking teeth 13 that mesh with the locking end 8.
Two sets of locking claws 7 are respectively inserted into the belt hanging cylinder portion 12 of 10, and when the driving rotor 4 is rotated in one of the front and rear directions, one of the two interlocking rotors 10 is Operate.

At this time, in one rotating interlocking rotor 10, the locking end 8 of the locking claw 7 of the drive rotor 4 comes into contact with and meshes with the teeth of the locking teeth 13. Rotational force is transmitted to the interlocking rotor 10.

On the other hand, in one interlocking rotor 10 that is not rotating, the lubricating arc 9 slides on the tip end of the engaging tooth 13 as the engaging pawl 7 of the drive rotor 4 rotates. However, with this sliding force, the interlocked rotor
10 does not rotate easily.

Further, conversely, when the drive rotor 4 is rotated in the direction opposite to the rotation direction, the action is reversed, the interlocked rotor 10 that has not rotated operates, and the interlocked rotor 10 that has rotated does not operate. .

As described above, two endless belt marks 3 can be operated by one drive rotor 4, and the number of rotors can be reduced.

(Embodiment) Next, a first embodiment will be described in detail with reference to FIGS. 1 and 2.

 Reference numeral 1 is a frame, which has a U-shape.

Reference numeral 2 denotes a bridge piece, which has a rod-like shape and is installed between the opening tip ends of the frame 1. In both cases, the material is metal such as aluminum and steel, or hard plastic.

Reference numeral 3 denotes an endless belt mark, which has printed characters or numbers on the surface, and is made of a rubber material.

Reference numeral 4 denotes a drive rotor, which has a toothed disc 5 and a shaft cylinder 6 fixed to the center of the toothed disc 5, and a set of two locking claws provided on the surface of the shaft cylinder 6. It consists of 7. Furthermore, the shaft cylinder 6
And the locking claw 7 provided on the surface of the shaft cylinder 6 has the toothed disc 5
It is provided on both sides of.

Further, the toothed disc 5, the shaft cylinder 6, and the locking claw 7 may be separate parts.

The two locking claws 7 have a shape along a certain rotation direction from the center to the outside, and the rotation directions of the left and right locking claws 7 are different. Further, the locking claw 7 is composed of the locking end 8 and the arc-shaped lubricating arc 9, and the number of the locking claw 7 is not limited.

Further, the diameter of the toothed disc 5 is the same as the assembled endless belt mark 3
Is bigger than that.

Reference numeral 10 denotes an interlocking rotor, which is provided with a disk 11 and a belt hanging cylinder portion 12 on one side of the disk 11, and further, an infinite number of locking teeth 13 provided on the inner wall circumference of the belt hanging cylinder portion 12. is there.

Here, the disk 11 and the band-hanging tube portion 12 may be separate parts. Further, the circular plate 11 is an endless belt mark 3 stretched on the belt hanging cylinder portion 12.
It is sufficient that the disk 11 has the same diameter as the above, and the thickness of the disk 11 is such that it can be separated from the adjacent endless band mark 3. Therefore, the disc 11 can be made very thin.

One of the interlocking rotors 10 is arranged on each side of the drive rotor 4.

Further, a long convex portion 14 along the direction of the fixed shaft 15 is provided on the surface of the band-hanging tubular portion 12 so that the endless band mark 3 does not slip.

The above-mentioned respective parts are combined as follows. The fixed shaft 15 is installed between the middle parts of the frame 1
A drive rotor 4 rotatable around and a interlocking rotor 10 rotatable on the left and right sides thereof. At this time, the endless belt mark 3, the bridge piece 3 and the belt hanging cylinder portion 12 of the interlocking rotor 10 are stretched.

Further, both the locking claws 7 on both the left and right sides of the drive rotor 4 and the left and right belt hooking cylinder portions 12 are inserted into the belt hooking cylinder portion 12 so as to lock with the lubricating arc 9. The teeth 13 are combined so that the tips thereof are in contact with each other.

Next, the second embodiment will be described in detail with reference to FIG.

In the second embodiment, the shaft cylinder 6 is stretched on one side of the center of the drive rotor 4, and the locking claws 7 having different rotation directions are provided in parallel, so that the locking teeth 13 come into contact with them. Interlocking rotors
10 are arranged in parallel. When the drive rotor 4 is rotated forward or backward, either the interlocking rotor 10 close to the drive rotor 4 or the next interlocking rotor 10 operates. The method of operation is the same as in the first embodiment.

(Effect) With the above configuration, one endless belt mark 3 can be rotated by one drive rotor 4.

As a result, the drive rotor 4 can be reduced and the endless belt mark 3
The distance between comrades can be reduced. Furthermore, a rotating rubber stamp having a neat appearance can be obtained.
