"Ironing machine"

The innovation concerns an ironing machine with an electric motor driven ironing roller and pivotably articulated ironing cheek, with a clutch that controls the bending torque of the Transfers the electric motor to the ironing cheek via a lever and presses it against the ironing roller «

Ironing machines with clutches are known in which both the pressing and lifting movements of the ironing « cheek, as well as the drive of the ironing roller are controlled independently of each other, this happens because next normal ironing processes - in which the laundry to be ironed is drawn in between the ironing cheek and the ironing roller, too

So-called pressing processes have to be carried out in which the laundry to be ironed is between The ironing cheek and the non-rotating ironing roller are located.

There are items to be ironed that are only normal for short distances]

is ironed, since the same must then be rearranged and drawn up. In these cases the ironing process must be

be switched on and off periodically. Furthermore,] ironing machines, in which the switching operations with relatively complex clutches are triggered in very precise tolerances, known.

The disadvantage of these ironing machines is that the tendency to jam is particularly evident here big is “On the other hand, these clutches are predominantly only designed for a certain type of machine.

A type of clutch is also known in ironing machines that work with gear wheels and dog clutches. But this arrangement also has the disadvantage that the dog clutches, as soon as they are in engagement, relatively difficult to shift "

Clutches for ironing machines that The help of spring band clutches work. Are further

Switching arrangements known in which the Biigelwange of a spring is pressed against the ironing roller. At the Lifting the Biigel cheek, the direction of rotation of the motor is switched and the Biigel cheek is lifted via a freewheel « However, this arrangement has the disadvantage that the motor, transmission and freewheel against the force of the spring have to work and become relatively expensive and time-consuming »

The inventor has now set himself the task of opening up an improved design in the aforementioned field in which the indicated disadvantages have been eliminated solved that the output shaft of the gear motor directly or via linkage, belt drive, gear drive or the like « connected to the ironing roller and the ironing machine to "connect the rotatably mounted gear motor = housing with the bow cheek, chain, gear transmission or the like. having.

According to the innovation, there is an elastic between the linkage Link in the form of a leaf spring or the like. " their radius of curvature is arranged changeable by means of an adjusting screw *. To protect against reverse viruses. the Ironing roller when lifting the ironing cheek is a freewheel

According to the innovation, the ironing machine frame is printed

Motor 2 connected gearbox 2 ¹ · arranged «The output« shaft 4 of the geared motor 2 is coupled to the ironing roller 3 »The housing of the geared motor 2 is labeled ^{ax 2f.} Casing to the rotatably mounted Getriebeeotorge- 2 * is an end of line 5, which centrally mounted fixedly ISTJ ₁ "is the free end of a lever mechanism with Yellenendes 6.7 _$ 8, 9 od.

To prevent backward rotation when lifting the bracket cheek 10, there is a freewheel 13 in the bracket roller 3 intended. On the ironing machine frame 1 there is a pressure switch 14 for switching off the motor current when it is reached the maximum lifting of the bow cheek 10.

The transmission 2 ¹¹ with the motor 2 is arranged within the ironing roller 3 in the exemplary embodiment. But there is also the possibility that the ironing roller 3 via a belt drive, gear drive or the like, not shown in the drawing. is driven by the gear motor 2, 2 ″.

If the motor 2 is switched so that the ironing roller 3 rotates in the direction of the ironing, one in the drawing is drawn not shown weak spring the ironing cheek 10 against the ironing roller 3 and thereby initiates the ironing process.

The effect of this spring may be wholly or partially replaced by _s that the Biigelvage 10 dureh its own weight against the ironing roller 3 presses * A further possibility _t initiate the pressing operation is given by the fact that the ironing cylinder 3 slightly braked during rotation in swing direction by a brake will. If the ironing roller 3 and thus the output shaft of the transmission 2 ^{11 is} braked, the reaction torque acts on the rotatably mounted housing 2 'of the motor 2 transferred and used to press the same 10 against the roller 3. Ever

The stronger the ironing roller 3 is braked during ironing by the ironing cheek 10, the stronger the counter-torque and thus the contact pressure of the ironing cheek 10. To avoid blocking the ironing cheek 10, the lever mechanism 6 _t 7,8-, 9 is already mentioned elastic member 11 in the form of a leaf spring or the like «arranged. If the bracket cheek 10 is to be lifted off, the gear motor 2 is switched over in its direction of rotation via a foot switch known per se. The ironing roller 3 is through the freewheel 13 or the like. prevented from rotating backwards, and consequently the motor housing 2 rotates the rotatably mounted shaft end 5 and lifts the bracket cheek 10 via the lever mechanism 6,7,8,9.

The lifting of the bracket cheek 1β is done by a pressure switch

When ironing again, the pressing process of the ironing cheek 10 is initiated by the fact that the motor 2 is switched on in the direction of the ironing via a foot switch (not shown) . The contact pressure remains because in this case too the motor 2 cannot be rotated ^{via the gearbox 2 1 '.}
