US 4,784,556 A · Device for the rearrangement of a pile of pictures

Abstract

The invention relates to a device for the cyclic rearrangement of a pile of rectangular or square pictures, with a first and a second frame part (12, 14), which can be moved back and forth parallel to the principal plane of the pile of pictures held by them, with a separator bar (20), arranged in the second frame part (14), which defines a separating through-gap for a picture and a return through-gap for the picture, with a retaining element in the first frame part (12) for retaining a picture taken from one end of the pile and guided through a separating through-gap, and with a guide element for shifting the retained picture transversely to the pile and returning it through the return through-gap to the other end of the pile, and with a viewing window (35) in one of the frame parts (12), wherein the two frame parts (12, 14) are coupled by way of a free-wheel-type device which, when the two frame parts (12, 14) are in the end position where they are pulled completely apart, frees the return movement and, in the end position where they are pushed completely together, frees the withdrawal movement, but when there is a change in the direction of movement blocks this at least in the two respective areas of reversal of withdrawal and return movement adjacent the two end positions.

Dependent claims

Apparatus for the cyclic rearrangement of a pile of rectangular or square pictures, said apparatus comprising:

a first and a second frame part which can be moved back and forth parallel to the principal plane of the pile of pictures held by said frame parts between a first end position and a second end position, each of said first and second frame parts having stop means, said stop means on said first frame part cooperating with said stop means on said second frame part to define said end positions;
a separator bar arranged in the second frame part which defines a separating through-gap for a picture and a return through-gap for the picture;
a retaining means in the first frame part for retaining a picture taken from one end of the pile and guided through said separating through-gap;
a guide means for shifting the retained picture transversely to the pile and returning it through the return through-gap to the other end of the pile;
a viewing window in one of the frame parts;
wherein
the two frame parts are coupled by way of a free-wheel-type device which, when the two frame parts are in the first end position, frees return movement toward the second end position and, when they are in the second end position, frees withdrawal movement toward the first end position, but prevents a change in the direction of movement at least adjacent the first and second end positions.

Apparatus for the cyclic rearrangement of a pile of rectangular or square pictures by removing a picture from one end of said pile and returning it to an opposite end of said pile, said apparatus having a first and a second frame part which can be moved back and forth, parallel to the principal plane of the pile of pictures held by said frame parts between a first end position and a second end position, each of said first and second frame parts having stop means, said stop means of said first frame part cooperating with said stop means on said second frame part to define said end positions, wherein the two frame parts are coupled by a free-wheel-type device which, at least over some regions of the movement of the frame parts, prevents a change in direction of movement.
