Abstract
A process and a device is provided for the positioning of bobbins which are delivered by a conveying device and are tilted from a conveyed position into a position from which they can be picked up by a grasper. Provisions are made for the bobbins to be brought into the desired position for pickup by the grasper. For this, further provisions are made for the tilting action to be triggered by the bobbin which is running up against a tilting surface and for the bobbin to be brought up against a stop so that the predetermined position is achieved.
Claims28
A process for positioning textile bobbins delivered by a conveying device for subsequent grasping by a grasping device, said process comprising the steps of:
- delivering the bobbin to a tilting device with the conveying device, the axis of the bobbin oriented substantially horizontal with respect to the conveying device;
- supporting the bobbin in its horizontal position upon a support surface of the tilting device;
- actuating the tilting device so that the bobbin is tilted approximately 90 degrees, wherein the bobbin axis is substantially vertical;
- substantially simultaneously with said tilting, positioning the bobbin on the tilting device so that the bobbin axis is essentially placed at a relatively constant position with respect to the tilting device regardless of the diameter of the bobbin, bobbins of varying diameters thus being positioned at the relatively same position for suitable grasping by a grasping device.
A device for positioning textile bobbins formed about a bobbin tube which are delivered from a conveying device with their axis oriented substantially horizontal to a position wherein their axis is substantially vertical for subsequent grasping by a grasping device, said device comprising:
- a tilting device, said tilting device including a support surface for receiving the bobbin from said conveying device in a substantially horizontal position;
- drive means for rotating said tilting device so that a bobbin carried thereby is tilted approximately 90 degrees to a substantially vertical position;
- and
- a positioning device configured integral with said tilting device, said positioning device further comprising means which operate substantially simultaneously with said tilting device for positioning bobbins in their vertical position so that the bobbin axis of bobbins with different outside diameters are at a relatively fixed predetermined position on said tilting device regardless of the diameter of the bobbins for subsequent pick-up by a grasping device.
