Automatic device for loading and unloading identical objects e.g. textile or yarn supports, on at least one machine and for conveying said objects between the machine, a take up area and a feed area for use particularly in the automatic doffing and donning operation of textile machines, and more especially, machines with vertical spindles, such as synthetic yarn drawing machines. The device includes at least two groups of cars having gripping and laying means. The first group is used for removing treated objects e.g. bobbin with yarn winding thereon, from the machine and conveying them to a take up area, the second group for conveying objects to be treated e.g. empty bobbins, from the feed area and positioning them on the machine.
An automatic device for donning and doffing bobbins on at least one textile machine, and for transporting said bobbins between a textile machine, a take-up area of full bobbins and a feed area of empty bobbins, comprising a guide circuit connecting the textile machine to said take-up area and to said feed area, and at least two independent means capable of traveling along the circuit and of stopping one after the other in front of the textile machine, the first means being fitted with a gripping means for simultaneous gripping of several bobbins and for the removal of said bobbins from the textile machine and for placing them on the take-up area, the second means being fitted with a gripping means for simultaneously gripping several empty bobbins from the feed area and positioning them on the textile machine.
