Description

Spindle bench moved up and down. A switching cam 8 is attached to the push rod 3.

On two threaded spindles 9 and 10, which are individually Can be driven at any speed and any direction of rotation are used as a limiter for changing the direction of the traversing stroke reversing switches 11 and 12 and for initiating a higher one Traversing speed attached to the Hubeüden control switches 13 and 14 adjustable. at the traversing movement of the push rod 3 driven by the piston 7 actuates the switching cam 8 Switches 11 to 14, which in turn control the hydraulic flow in the cylinder 6 according to the direction and amount of flow per unit of time

The threaded spindles 9 and 10 are driven by a motor 15 reversible in its direction of rotation via a clutch not shown in the drawing, located in a gear housing 16 and controlled by a switchgear cabinet 17. * ° A circular switching disk 18 of the switching cabinet 17, which is also driven by the motor 15, has on its circumference at different distances from the switching disk axis of rotation for each switching path 19, 20 specially shaped control cams 21, 22 which differ in length from one another the duration of the coupling of the threaded spindles 9, 10 to the motor 15 During operation, only one stopping section 19 or 20 is in action. 3 <>

In order to be able to switch the production program to laps of other lengths, are on the threaded spindle 9 in the desired winding length spacing in addition to switches 11 to 14 em reversing switch 23 for the desired change in direction of the traversing stroke and a control switch 24 for acceleration the stroke movement on the hand ^ actuation of a winding length selector switch (not shown) the previously in operation - 12 or the control switch 14

Control and switching device for hydraulic total winding length corresponds to this lisch driven traversing devices at 5 maximum distance of the reversing switch, the zwi-spinning, Twisting and, in particular, stretch twisting, see both of them in the course of a complete unwinding, in which the direction change of the winding process assumed extreme positions Traversing stroke of each reversing switch can be according to the preselected pro. gram adjustable electric reversible scarf- If you want to change the length of the roll to be formed tern is triggered by their adjustment organization, εο must be the distance between the reversing nen be set along the path of a switch from the traversing organ accordingly. That alone driven and on the reversing switch is not sufficient if the shape of the new winder acting switching cam can be moved, since it should be similar to that of the old one. It's easy to characterized in that to see that with the same traversing stroke speed represent the time between two reversals of the stroke of coils with different winding speeds length at one or both ends of the stroke at the same end of the winding, the greater the longer the bes of the switching cam (8) is on the adjustment organ stroke. and that one, around the same bevel of the nen (9, 10) several reversing switches (12, winding ends for windings of different lengths 23) are provided. to achieve the shifting movement of the limit switch 2. Apparatus according to claim I, with control 20 ter must slow down, the longer the roll should be, switches for the stroke acceleration on the stroke and vice versa. Therefore, when changing the end next to the reversing switch, thereby marking the winding length next to the setting of the new label, that in a known manner each of the stands between the reversing switches still additional reversing switches (12, 23) each have their own control settings such as the conveyor speed switch (14, 24) is assigned. 25 of the adjusting elements of the reversing switch and, if 3.
