Abstract

The present invention relates to transmission device for plotters characterized in that it comprises at least a freely rotating first wheel (2) arranged between the motor tube (5) and the winder tube (6) of a plotter, such that the rotation of the motor tube (5) is transmitted to said winder tube (6) through said freely rotating first wheel (2). It may also comprise a pair of freely rotating wheels (3) that are constrained to rotate together by contact, arranged between said motor tube (5) and said winder tube (6), one wheel of said pair of wheels (3) being in contact with said motor tube (5) and the other wheel of said pair of wheels (3) being in contact with said winder tube (6). It facilitates the change from direct to inverse transmission without having to use tools, and it achieves a clutch effect as the result of the sliding of the wheels with respect to the tubes.

Claims

1. A transmission device for plotters comprising at least a freely rotating first wheel (2) arranged between the motor tube (5) and the winder tube (6) of a plotter, such that the rotation of the motor tube (5) is transmitted to said winder tube (6) through said freely rotating first wheel (2).

2. The transmission device according to claim 1, further comprising a pair of freely rotating wheels (3) that are constrained to rotate together by contact, arranged between said motor tube (5) and said winder tube (6), one wheel of said pair of wheels (3) being in contact with said motor tube (5) and the other wheel of said pair of wheels (3) being in contact with said winder tube (6).

3. The transmission device according to claim 1, wherein said first wheel (2) is arranged at one end of said transmission device, and said pair of wheels (3) are arranged at the other end of said transmission device.

4. The transmission device according to claim 3, comprising a pair of shafts (4) located at the ends of the transmission device, in the opposite part with respect to said wheels (2, 3) for the assembly thereof as direct transmission or inverse transmission.

5. The transmission device according to claim 2, wherein said first wheel (2) is arranged at one end of said transmission device, and said pair of wheels (3) are arranged at the other end of said transmission device.

6. The transmission device according to claim 5, comprising a pair of shafts (4) located at the ends of the transmission device, in the opposite part with respect to said wheels (2, 3) for the assembly thereof as direct transmission or inverse transmission.
