Description

June 18, 1957 W..STUTZ DEVICE FOR TREATING BOBBINS Filed Dec. 29, 1954 DEVICE FOR TREATING BOBBINS Waiter Stutz, Kempten, near Wetzikon, Switzerland, assignor to Stutz & Cie, Kempten, near Wetzikon, Switzerland Application December 29, 1954, Serial No. 478,443 3 Claims. (Cl. 164-47 The present invention relates to a device for treating bobbins, and more particularly those bobbins which are to be led to a cleaning machine in order to have their thread waste removed.

As is well known there is always a waste left on the bobbins ejected by automatic looms. Such waste is usually removed in a so-called cleaning machine, to which the bobbins to be treated are fed in relatively large number per time unit. Preferably the bobbins, ejected from the looms and collected for example in a small carriage, are poured into a transport container and fed by the latter to the cleaning machine. Now during such handling of the bobbins entanglement of the ends of the thread wastes is inevitable. The thus interconnected bobbins must be separated in order to be correctly treated, this separation having heretofore been effected by pulling apart the entangled bobbins.

The present invention aims to avoid this time-wasting hand-work. For this purpose the invention provides a device for treating bobbins, destined to be fed to a cleaning machine for removal of the thread waste, comprising a guiding chute adapted to receive the bobbins, said chute having a cutting device for separating bobbins connected to each other by entanglement of their thread waste.

Other advantages and features of the invention will become apparent from the description now to follow, of two preferred embodiments thereof, given by way of example only, and in which reference will be made to the accompanying drawings, in which:

Fig. 1 is an elevational view of the first embodiment;

Fig. 2 is a partial side elevation to Fig. 1;

Fig. 3 is an elevational view of the second embodiment, and

Fig. 4 is a top view of the embodiment shown in Fig. 3.

In the first embodiment an inclined guiding groove or chute 1, of which only the lower portion is represented in Fig. l, is connected to a not represented bobbin catcher. This guiding groove or chute 1 is not represented in Fig. 2. On the inclined bottom 2 of the chute, the bobbins glide towards a distributor device 3 (see also Figs. 3 and 4) by which the bobbins coming from the said catcher are separated into at least two streams. The distance between the two sidewalls of the chute, is smaller at the lower end portion of the chute, than it is in the upper portion of the chute. The bottom 2 of the chute is provided at the lower end portion thereof with a slot 4 providing for the passage of a circular cutting disk 5. This disk is rotated by a motor 7 through a belt 6. Reference numeral 8 designates a support for the cutting device constituted by the motor 7, the belt driving 6 and the cutter 5. A safety cover 9 provided in the chute 1 encloses a large part of the cutter portion projecting into the latter, leaving free the slot 4 at the side facing the oncoming bobbins only. As visible from Fig. 2 the substantially flat safety cover 9 forms an innited States Patent O 2,196,126 Patented June 18, 1957 clined guiding surface. By the provision of the safety cover 9 it is avoided that the holding rings provided at the thickened end of the bobbin or the point thereof come into contact with the cutting disk. Likewise accidental touching of the cutter with the hands is effectively prevented. The thread waste, however, is pulled towards the cutter 5 in the zone of'the upper end portion of slot 4 and cut so that the desired separation of the entangled bobbins is attained.

The embodiment illustrated in Figs. 3 and 4 differs from the aforedescribed example in several respects. In this second embodiment a vertical guiding 10 is provided in the chute 1, said guiding 10 housing a straight, toothed cutter 11 supported by its back and two sides in the guiding 10. The cutter 11 is connected by its lower end by means of an arm 12 to an eccentric tap of a driven disk 13 so that an up-and-down movement is imparted to the cutter when the disk 13 rotates. Reference numeral 9 designates again a protective cover provided in the chute 1, this cover enclosing the larger part of the cutter but leaving free the upper end portion of the slot 4 in the bottom of the chute so that the thread waste may come into contact with the cutter. Reference numeral 14 designates the bobbin catcher, the bottom of which is constituted by the upper surface of an endless conveyor belt 15 a portion of which also serves as a movable bottom for the chute 1, in contradistinction to the embodiment of Figs. 1 and 2 in which the bottom 2 of the chute is stationary. The conveyor belt 15 passes over two

rollers

16 and 17 connected by a belt driving 18 operable by a hand wheel 19. Reference numeral 20 designates supporting rolls provided on the carrying side of the conveyor belt 15 and supported on the frame 21 of the catcher 14. By corresponding rotation of the hand wheel 19 it is possible to move the conveyor belt 15 so that it feeds bobbins towards the cutter 11.

The cutting device could also be provided with several cutters instead of one as illustrated in the foregoing embodiments. The rotational cutting disk could also be replaced by a to-and-fro swinging cutting disk or scissors-like or knife-like cutting devices could be provided. The bottom of the chute 1 could be arranged to be movable in the feed direction of the bobbins over its whole length instead of over a portion thereof only, as in the second embodiment.

I claim:

1. In a device for treating bobbins destined to be fed to a cleaning machine for removal of the thread waste, the provision of a guiding chute have an inclined bottom and a discharge portion of a smaller width to provide a restricted pathway, a slot in said bottom arranged centrally of said restricted pathway, a cutting device partly projecting through said slot for cutting the thread waste of bobbins entangled by the thread waste, a protective cover partly enclosing the portion of the cutting device projecting into said chute and leaving free the slot on its end facing the oncoming bobbins and having its opposite end constituted as a guiding surface, said protective cover being mounted centrally of said restricted pathway such that bobbins will pass along opposite sides thereof.

2. In a device for treating bobbins destined to be fed to a cleaning machine for removal of the thread waste, the provision of a guiding chute having an inclined bottom movable in direction of feed of the bobbins at least over a portion of its length, said chute being provided with a small discharge portion providing a restricted throat, a slot in said bottom, a cutting device device projecting into said chute and leaving free the slot on its end facing the oncoming bobbins and having itsppposite endjconstituted as a guiding surface; said cutting device and protective cover being arranged centrally of said restrictedthroatsuch that bobbins will pass therethrough on opposite sides: of said cuttingdevice. 3. In a device-for treating bobbins destined to be fed to a cleaning machine for removal of the thread waste, the provision of a guiding chute having a slot in its bottom and provided with a small discharge portion providing a restricted pathway, a cutting device having at least one movable cutting member partly projecting through said slot for cutting the thread waste of bobbins entangled by the thread waste, a protective cover partly enclosing the portion of the cutting device projectinginto said chute and leaving free the slot on itsend facing the oncoming bobbins and having its opposite end constituted 4 as a guiding surface, said cutting device and protective cover being mounted centrally of said restricted pathway such that bobbins will pass downwardly on opposite sides thereof and the entangling threads will pass along the base of said protecting coverto be engaged by said cutting device.
