This invention relates to a collector system for elongated articles as used, for example, in weft winding machines having a conveyor arrangement to remove the wound p It is one of the primary objects of the invention to provide means affording the transfer of pirns in substantially parallel and aligned positions with respect to each other to a collector receptacle, whereby such collector system may be either built onto existing weft winding machines or may be readily incorporated in new winding machines so that the removal of the weft pirns is automatically achieved and the receptacle is charged with said pirns while the same remain in aligned and parallel positions with respect to each other. 7

It is another object of the present invention to provide means facilitating the supply of pirns and like elongated articles from conveyor means to collector means in a substantially orderly and predetermined fashion, whereby said pirns are supplied to or discharged into a collector receptacle gradually while their aligned positions are substantially maintained.

It has hitherto been usual to charge the elongated articles or weft pirns into a container by hand, or to allow them to fall down an inclined chute or a distributing hopper into a box. Falling freely, the pirns do not always align themselves parallel to one another, with the result that they have to he repositioned, or aligned, by hand. A particularly serious disadvantage, however, resides in the fact that owing to the impact of the pirn on falling the strength and the arrangement of the layers of yarn, especially in yarns of fine count, are adversely affected.

The drawbacks just referred to are eliminated by the present invention which renders the possibility of transferring a supply of pirns in parallel relation to each other along a conveyor arrangement from which said pirns are further moved onto a collector band reaching into a collector receptacle, whose top end is substantially level with said conveyor arrangement, said collector 'band under the influence and weight of said weft pirns receding into said receptacle without substantially disturbing the parallel and aligned relationship between the pirns thus discharged into the receptacle.

The collector band is preferably operatively connected to a brake roller for releasing said collector band step by step into said receptacle, whereby the collector band is partly wound around said roller and the braking or drag power of the latter is so calculated that the retraction of the band into the container under the weight of the weft pirns takes place gradually, so that the pirns, unable to fall indiscriminately, retain their parallel alignment.

The drawing shows diagrammatically a typical embodiment of the invention, in which drawing:

Fig. 1 is a lateral elevation of the invention showing only the essential parts;

Fig. 2 is an end elevation of the receptacle or container taking the form of a packing bag in its suspension device.

A conveyor band 1, which expediently extends throughout the length of the weft winding machine (not shown), is driven in the direction of the arrows by a drive motor or by the main drive shaft of the machine through the intermediary of a wormwheel transmission gear (not shown), and conveys the elongated articles or pirns 2, as they arrive, in the leftward direction to the packing arrangement (Fig. 1). The paralleling device consists of a press-plate 4, adjustable for height and spring-mounted, is disposed in the path of the pirns, the reception end of which press-plate is slightly upturned and which pressplate encompasses the exact aligning of the weft pirns transversally to the lengthwise axis of the conveyor arrangement. Adjustment of the height of the press-plate 4 is effected by means of screws 3.

The weft pirns are then impelled into a flat channel consisting of an intermediate plate 5 and an upper mem ber 5a. The thrust of the further weft pirns as they arrive impels forward those lying in front of them, which therefore pass on to a collector band 7 which is of a width approximately equal to the length of the weft pirns and, under the weight of the pirns, slowly recedes into the packing bag 12. The band is provided with eyelets which are slipped on to holding pegs 9 a guide roller 6 on to a braked roller 8 on to which it is preferably partly wound. I

The band or collector element 7 is provided with three portions, of which one portion extends into the path of the aligning or paralleling means 35, a second portion reaches into the receptacle or bag 12 and a third portion is engaged by releasing means 10, which includes a brake roller 8.

The braking and release arrangement, which f0 erab-le means and may consist of a friction brake 10 and a loading weight 11, is so balanced that the subsidence of the band takes place gradually.

Designated by the numeral 13 is a flap which is kept open until the container is full. In order to avoid interruption of the operation of the weft winding machine from the moment of removal of the receptacle until the fitting of a new, empty receptacle, the flap 13 can be swung downwards into the position shown by the broken line, with the result that the weft pirns, as they arrive, will accumulate until the flap 13 is opened again.

When the bag 12 is full, the collecting band 7 is detached from the pegs 9 and '9a, and the bag itself, which is suspended by lateral flaps from the pegs 16 of the packing device, is detached and wheeled out of the packing device by means of a trolley plate 15 travelling on rails 14.

The trolley arrangement 14, 15 is important because it enables the personnel tending the weft winding machine, which personnel generally consists of one woman, to remove the packing bag, which may weigh anything up to about lbs., unaided, and to suspend a new packing bag in its place, without interrupting the running o f the machine. The packed bags can then be sewn up or made ready for transport in some other way.

Although in the embodiment illustrated the receptacle is shown as a packing bag, it is obvious that the invent-ive device can, without modification, be used in conjunction with other receptacles or containers, such as wooden cases, sheet metal bins, or the like.

In general it will be understood that my invention is not limited ms opframe, means for removably supporting said receptacle on said frame when the/former has been filled with pirns,
