JPH0719740Y2 - Shifting device for lateral movement of round knife carrier of round knife type roll paper cutter - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a device for shifting the lateral movement of a round knife carrier of a round knife type roll paper cutter used for cutting roll paper for recording in a facsimile machine or the like. .

[Prior Art] The conventional horizontal knife roll paper cutter The shift of the left-right movement of the round knife carrier is performed in the following manner.

Microswitches are provided at the left and right ends of the guide for the left and right movements of the round knife carrier, and the microswitches are mounted such that their hinge lever-type actuator faces face the round knife carrier, and the actuators of the round knife carrier itself are mounted. Was touched by a shift.

[Problems to be solved by the invention] The shift microswitch having the above-described shift configuration also switches ON / OFF of the current, but at this time, since the working distance of the hinge lever of the actuator is small, the machine of the round knife carrier There is also a problem that an abnormal stopper action also occurs and abnormal vibration occurs during shift.

The present invention has been made in view of the above problems, and provides a shift device for the horizontal movement of a round knife carrier of a round knife type roll paper cutter that does not generate abnormal vibration when the round knife carrier is shifted. Is intended.

[Means for Solving the Problem] The present invention is directed to a round knife carrier which is mounted on a round knife type roll paper cutter and travels on a traveling guide, and to move laterally off the axis of the moving space of the round knife carrier. Microswitches provided on both sides of the space for shift-controlling the movement of the round knife carrier, and a shift plate laterally long in the moving direction of the round knife carrier fixed to the round knife carrier are provided. A round knife protector which covers the front face of the round knife mounted on the round knife carrier and is provided on both sides of the round knife protector so as to be offset from the mounting position of the round knife carrier, and corresponding to the above-mentioned microswitch, along with the movement of the round knife carrier. It is equipped with a dog that presses the micro switch.

[Embodiment] An embodiment of the present invention will be described below in detail with reference to the drawings.

1 is a front view showing an embodiment of the present invention, FIG. 2 is a side view of an embodiment of a shift plate according to the present invention, and FIG. 3 is a plan view of FIG.

In each of the above figures, the shift device for the horizontal movement of the round knife carrier of the round knife type roll paper cutter of the present invention is
A round knife carrier 2 having a round knife 4 mounted thereon, and a horizontally long shift plate 1 fixed to the round knife carrier 2,
And a micro switch 3 which is operated by a shift plate 1 to shift the round knife carrier 2.

The round knife carrier 2 carries a round knife 4 and runs on a running guide (not shown), and the round knife 4 cuts the roll paper along with this running.

The shift plate 1 has a horizontally long plate shape as a whole, and includes a round knife protect portion 1a for covering the front surface of the round knife 4 and dogs 1b provided on both sides of the round knife protect portion 1a.

The dog 1b is provided so as to be displaced from the movement direction axis of the mounting position of the round knife carrier 2, and is formed by an elastic body that is bent in a dogleg shape and can be bent in the lateral direction of the movement direction of the round knife carrier 2. ing.

The micro switches 3 are provided on both sides of the moving space of the round knife carrier 2, and the round knife carrier 2 is provided in each side.
Is laterally offset from the axis of the moving space.
It corresponds to the axis of the dog 1b of the shift plate 1. Therefore, when the round knife carrier 2 travels on the traveling guide and reaches the end, the dog 1b pushes down the micro switch 3 to shift-control the round knife carrier 2.

Since the microswitch 3 is removed from the movement route of the round knife carrier 2, the current is switched by the contact between the dog 1b and the actuator, while the round knife carrier is stopped,
The shift is smoothly performed without physical contact or collision.

The round knife protector 2 prevents troubles such as the end of the cut paper getting caught in the round knife 4.

[Effects of the Invention] As described above, the present invention is provided with a round knife type roll paper cutter, and a round knife carrier that travels on a travel guide, and a round knife carrier that moves laterally away from the axis of the moving space of the round knife carrier. Microswitches provided on both sides of the space for shift-controlling the movement of the round knife carrier, and a shift plate laterally long in the moving direction of the round knife carrier fixed to the round knife carrier are provided. A round knife protector that covers the front surface of the round knife that is mounted on the round knife carrier, and is provided on both sides of the round knife protector, offset from the mounting position of the round knife carrier,
By providing the dog corresponding to the above-mentioned micro switch, which pushes down the micro switch with the movement of the round knife carrier, the round knife carrier does not collide with or come into contact with the micro switch, and the round knife carrier due to collision etc. This has the effect of eliminating abnormal vibration when shifting to the left and right.

Further, since the round knife is also covered with the shift plate, there is an effect that it is possible to prevent troubles such as cutting paper getting caught in the round knife.
