## Abstract

An apparatus for depositing cross wound yarn spools into an open top transport container utilizing a vertically extending dropping channel. The channel is raised and lowered into the transport container for guiding and directing the spools of yarn into the container. The container with the dropping channel provided therein is selectively moved for depositing the spools in a plurality of longitudinal rows.

## Claims

### Claim 1

An apparatus for depositing cross wound yarn spools into an open top transport container comprising:
an open top vertical dropping channel extending into said transport container;
said dropping channel including front and rear walls joined by side walls, said front and rear walls being spaced apart a distance slightly greater than the length of said yarn spool for receiving and guiding said spool therebetween into said transport container;
means shifting said dropping channel and transport container horizontally in a first direction a distance corresponding to the length of a spool facilitating the deposit of more than one vertical row of said spools in said container;
means conveying said spools in said first direction to said open top of said dropping channel for depositing same in said container;
means selectively raising said channel out of said transport container after a vertical row of said yarn spools stacked upon one another has been deposited; and
means for selectively lowering said channel into said transport container after shifting of said container positioning said channel next adjacent said vertical row previously formed whereby successive vertical rows are formed along the length of said container in said first direction.

### Claim 2 (depends on 1)

The apparatus as set forth in claim 1 further comprising:
said shifting means includes means for shifting said channel a distance in said first direction greater than the length of a spool, said channel abutting a previously formed vertical row of said spools urging same in said first direction facilitating compact loading while shifting said container horizontally.

### Claim 3 (depends on 1)

The apparatus as set forth in claim 1 further comprising:
said shifting means including adjusting means varying the distance said channel shifts horizontally.

### Claim 4 (depends on 1)

The apparatus as set forth in claim 1 further comprising:
means deforming said rear wall of said channel elastically inwards.

### Claim 5 (depends on 1)

The apparatus as set forth in claim 1 further comprising:
said rear wall including a pair of walls spaced apart from each other defining an inner and outer wall; and
means for elastically deforming said inner wall of said pair of walls inwardly.

### Claim 6 (depends on 5)

The apparatus as set forth in claim 5 wherein said means for elastically deforming said inner wall includes a compressed air cylinder.

### Claim 7 (depends on 5)

The apparatus as set forth in claim 5 further comprising:
means for elastically deforming said inner wall at a distance from the lower end of said dropping channel which corresponds at least to half the diameter of a cross wound yarn spool retarding the fall of same before engaging said container at the lower end of said channel.

### Claim 8 (depends on 5)

The apparatus as set forth in claim 5 further comprising:
a yarn spool scanning means for detecting the presence of a spool adjacent the top of said channel for activating said means for elastically deforming said inner wall respectively thereto.

### Claim 9 (depends on 1)

The apparatus as set forth in claim 1 further comprising:
means for adjusting the distance between the front and rear walls of said channel to accommodate yarn spool sleeves of different lengths.

### Claim 10 (depends on 1)

The apparatus as set forth in claim 1 further comprising:
an upper part of said rear wall being swivable;
means for swivelling said rear wall;
means for controlling the swivelling movement of said upper part of said rear wall inwardly towards the interior of said channel responsive to raising to said dropping channel.

### Claim 11 (depends on 10)

The apparatus as set forth in claim 10 further comprising:
cam means for causing said swivelling movement responsive to said raising of said channel.

### Claim 12 (depends on 1)

The apparatus as set forth in claim 1 further comprising:
a transport belt for conveying said spools to said open top dropping channel in said first direction.

### Claim 13 (depends on 12)

The apparatus as set forth in claim 12 further comprising:
guide means carried on the side of said transport belt for guiding said spools thereon.

### Claim 14 (depends on 12)

The apparatus as set forth in claim 12 further comprising:
a trolley carrying said transport belt and said dropping channel.

### Claim 15 (depends on 14)

The apparatus as set forth in claim 14 further comprising:
a frame for guiding said dropping channel; and
means for shifting said trolley in a direction transverse to said first direction in which said container is shifted.

### Claim 16 (depends on 14)

The apparatus as set forth in claim 14 further comprising:
means for clamping said transport container in said trolley facilitating shifting of said container by engagement by said dropping channel.

### Claim 17 (depends on 12)

The apparatus as set forth in claim 12 further comprising:
a second transport belt for delivering cross wound yarn spools to said first mentioned transport belt; and
means for driving said second transport belt at a slower speed than said first mentioned transport belt.

### Claim 18 (depends on 1)

The apparatus as set forth in claim 1 further comprising:
said dropping channel increasing in width towards its lower end.

### Claim 19

An apparatus for depositing cross wound yarn spools into an open top transport container comprising:
an open top vertical dropping channel extending into said transport container said channel having front and rear walls, said front and rear walls being spaced apart a distance slightly greater than the length of the sleeve of said yarn spool for receiving and guiding said spool therebetween into said transport container;
means conveying said spools to said open top of said channel for deposit in said container;
said channel depositing said spools forming a vertical row of spools stacked vertically upon one another;
said channel having a lowered position in which said spools are deposited therein and a raised position in which said channel is raised above said spools;
means raising and lowering said channel; and
means shifting said channel horizontally in a first direction when in said lowered position urging said channel against a previously formed vertical row compacting said spools in said container and shifting said container to accommodate the deposit of another row of said spools;
whereby successive vertical rows of said spools are formed in said container.

### Claim 20 (depends on 19)

The apparatus of claim 19 further comprising means shifting said channel horizontally opposite to said first direction after said channel has been raised.
