- core H gripped by the core receptacle 40 becomes.
- the two spring-loaded jaws 44, 46 apart against the spring force pressed.
- a special application or control of the Core receptacle 40 is not required.
- the respective core H becomes rather inevitably taken up with the placement of the core receptacle 40 in this and held.
- the core changing process can then begin again.
- Figure 6 shows a simplified, purely exemplary circuit diagram of the Control device 64 comprising winding device.
- control device 64 is in particular the position for the positioning the positioning arm 38 (cf. FIG. 1) detecting the sensor 76, the sensor 68 assigned to the core receptacle 40, to which the rest position of the positioning arm 38, the sensor 78 which detects the takeover area 42 of the core magazine 36 monitoring sensor 80 and the Winding holder 34 (see FIG. 1) on an ejected cotton wrap 12 monitoring sensor 120 coupled.
- control device 64 has two lines with three each Valves 132, 134 and 136 connected. As can be seen in FIG. 6 can, the two valves 132 and 136, for example, each by a 5/3-way valve and the valve 134, for example by a 5/2-way valve can be formed.
- valve 132 controlled by the control device 64 Via the valve 132 controlled by the control device 64 the two cylinder / piston units 84, 86 of the front locking device 82 (see FIGS. 1 and 4) associated drive actuated. That from the control device 64 controlled valve 134 is used to actuate the assigned to the rear locking device 106 (cf. FIGS. 1 and 5) Cylinder / piston unit 108. Via the third from the control device 64 controlled valve 136 becomes the drive 66 of the positioning arm 38 forming cylinder / piston unit actuated.
- control device 64 the two control inputs Y1 and Y2 of the valve 132 can be acted upon. If the belt drive is switched on, the right control input is Y2 acted upon, while the left control input Y1 remains unused. In this case it is the cylinder / piston units 84, 86 front locking device 82 activated.
- valve 132 If the sensor 76 detects that the positioning arm 38 is its lower one Has reached the positioning position, the right control input Y2 of valve 132 is acted upon, while left control input Y1 is not acted upon remains. So that the front locking device 82 on the two cylinder / piston units 84, 86 reactivated.
- the two control inputs Y3 are also via the control device 64 and Y4 of the valve 134 can be acted upon.
- the left control input becomes Y3 acted upon, while the right control input Y4 remains unused.
- the rear cylinder cylinder-piston unit 108 is included Locking device 106 activated. If it is now determined via the sensor 80, that no core H is present in the take-over area 42 of the core magazine 36 , the right control input Y4 is applied while the left control input Y3 remains unoccupied. This will make the rear one Locking device 106 deactivated via the cylinder / piston unit 108, around a respective core H for transfer into the takeover area 42 release.
- the left control input Y3 is then applied again during the right control input Y4 remains unused, causing the rear locking device 106 is reactivated. If still via the sensor 80 no message about the presence of core H in the takeover area 42 is present, this routine just described is repeated. Delivers the Sensor 80 still no corresponding signal, so an error message are generated, which indicates that in the takeover area 42 no Core H is present.
- valve 136 Two control inputs Y5 and Y6 of valve 136 is applied.
- the positioning arm 38 can in particular in its upper To be held at rest.
- the valve 136 thus takes a middle position a, in which the positioning arm 38 in particular for safety reasons is held in its respective position.
- the positioning arm is thus 38 at least between the takeover position in which he has a respective Kern H from Kemmagazin 36 takes over, and the positioning position adjustable, in which he delivers the core H in the defined winding position.
- the deflection roller R3 for example, to during the transfer of the core H to the winding position Compensate for belt length changes occurring in sections. Both the transfer of the core H in the winding position and the Compensation for the belt length shift is at least partially automated and controlled by the controller 64.
- the control device 64 can expediently be designed in this way be that a respective displacement of the belt 20 by the preferably the compensating means comprising the deflection roller R3 only takes place, after the release of the positioning arm 38 for a respective transfer of the core H in the winding position a predetermined time elapsed is.
- a signal For example, after a signal occurs, it becomes a core handover the lock in the sleeve channel is released, whereupon the positioning arm is pivoted downwards.
- This also becomes a timer for the control the compensation means triggered by a predeterminable delay time of about 3 seconds, for example.
- the sleeve-like core is then pressed against the belt.
- the timer releases the control for the compensating means R3, whereby the belt is displaced that the tracked core are transferred to the winding position can.
- the belt shift is stopped.
- the sleeve-like core is now clamped between the winding disks, whereupon the positioning arm is pivoted back into the neutral position becomes.
- the swiveled out pulley is swiveled in again, whereupon the winding process is started.
- control device 64 with at least one the position of the Core H or the positioning arm 38 monitoring sensor 76, 78 coupled is a respective displacement of the belt 20 by the Compensating means comprising deflection roller R3 also as a function of the relevant sensor signals are triggered.
- a timer is not used. Rather is about appropriately arranged sensors the position of the core or the positioning arm supervised. As soon as the sensor or sensors in question respond, the sleeve-like core lies with the correct tension on the Strap on. Thereupon the relocation is carried out via the control device the deflection roller R3 assigned to the compensating means triggered so that the core can be transferred into the winding position.
