Method of and device for feeding electric and/or electronic elements to given positions
First Claim
1. A method of feeding and transferring elements, comprising feeding a series of elements along a feed path in a feed direction, so as to move the elements one at a time to a transfer position;
- and transferring an element from said transfer position in a transfer direction by a transfer member,characterized by the additional steps ofdefining said feed path by a feed channel enclosing said series of elements on all sides except in the transfer direction, said feed channel having a removal opening at the transfer position to permit movement of an element in the transfer direction,moving an end of an elongated part of a transfer member through said removal opening into contact with one side of an element at the transfer position,moving an ejection pin into contact with the other side of the element,pressing the element out of the respective transfer position by further movement of the ejection pin, while holding the element between the ejection pin and the elongated part, andthen holding the element by the transfer member and transferring the element to another, selected position.

Abstract
A method for feeding chip components to positions in which they can be picked up by transfer members, in which the chips are pushed out of a feed channel while being held between an ejection pin and a transfer member part. An elongated part of a transfer member is advanced into a feed channel into contact with one side of a chip, an ejection pin then advances to the other side of the chip and pushes the chip and transfer member out of the feed channel through a removal opening, and the chip is then held by the transfer member while the ejection pin retracts. Preferably, a cover plate prevents movement of the chips toward the transfer member until the member is in contact with the side of the chip.

1. A method of feeding and transferring elements, comprising feeding a series of elements along a feed path in a feed direction, so as to move the elements one at a time to a transfer position;
- and transferring an element from said transfer position in a transfer direction by a transfer member,
characterized by the additional steps of defining said feed path by a feed channel enclosing said series of elements on all sides except in the transfer direction, said feed channel having a removal opening at the transfer position to permit movement of an element in the transfer direction, moving an end of an elongated part of a transfer member through said removal opening into contact with one side of an element at the transfer position, moving an ejection pin into contact with the other side of the element, pressing the element out of the respective transfer position by further movement of the ejection pin, while holding the element between the ejection pin and the elongated part, and then holding the element by the transfer member and transferring the element to another, selected position. - View Dependent Claims (2, 3, 4)

5. A method of feeding and transferring a plurality of series of elements, comprising feeding a plurality of series of elements along a corresponding plurality of parallel feed paths in a feed direction, so as to move the elements one at a time to a corresponding plurality of transfer positions;
- and transferring an element from said transfer position in a transfer direction by a transfer member,
characterized by the additional steps of defining said feed paths by a corresponding plurality of respective feed channels enclosing each of said series of elements on all sides except in the transfer direction, each of said feed channels having a respective removal opening at the transfer position to permit movement of an element in the transfer direction, simultaneously moving an end of a corresponding elongated part of each of a corresponding plurality of respective transfer members through each respective removal opening into contact with one side of an element at the respective transfer position, moving a respective one of a corresponding plurality of ejection pins into contact with the other side of each respective element, simultaneously pressing the elements out of the respective transfer positions by further movement of the ejection pins, while holding the elements between each respective ejection pin and elongated part, and then holding each element so pressed out by the respective transfer member and transferring the element to another, selected position. - View Dependent Claims (6, 7, 8)

9. A device for heating and transferring a plurality of series of elements, comprising
a plurality of feed channels arranged substantially parallel with each other, each channel defining a feed path and enclosing said path on all sides, and having a removal opening at an end of the channel, said removal openings being arranged in a straight line, a corresponding plurality of transfer members disposed opposite each respective removal opening, means for moving the transfer members in a transfer direction transverse to said feed direction, characterized in that each of said transfer members comprises an elongated part having an end disposed toward the feed channel, said means for moving the transfer member includes means for moving said elongated part through said removal opening into contact with one side of an element located at the transfer position aligned with said opening, and the device further comprises a corresponding plurality of ejection pins disposed to the other side of the feed channel opposite respective elongated parts, and means for first moving each respective elongated part until it contacts a respective element at the transfer position, subsequently displacing the respective ejection pin together with the element and the elongated part, and then holding the element by the transfer member and returning the ejection pin to its initial position.
