An axially leaded diode (12), travelling at a high rate of speed in a longitudinal direction, is terminated within a bin assembly (18). The bin (18) has first and second ends (43 and 44) and first and second sidewalls (21 and 22) including magnets (33-41) therein to orient a diode (12) transversely to such sidewalls. A tube (48) guides the diode (12) on a path forming a given angle 'A' with the sidewalls (21 and 22). A discharge end (49) of tube (48) is located at the first sidewall (21) such that the diode (12) is discharged toward the second sidewall (22). A deceleration apparatus (54) is provided at discharge end (49) of tube (48) and spaced therefrom. Apparatus (54) includes a vertical bar (65) with a row of deceleration elements (66) extending therefrom toward the first end (43) of the bin (18). The row of elements (66) provides a penetrable restraint (64) such that a first lead (14) of a diode (12) discharged from tube (48) penetrates between the elements (66). The body (16) of the diode (12) impinges upon and is slidably restrained along the elements (66). As the diode (12) advances out of the elements (66) said diode is rotated to an orientation transverse of bin (18).

Decelerating and reorienting elongated magnetic articles

Elongated magnetic articles 12 are introduced into vacant positions 31 on a carrier wheel 18 for a given operation. A magnetic bin 40 has a feed end in communication with wheel 18 and includes spaced sidewalls 41-44, with arm sections 43-44 thereof extending substantially beyond the periphery of wheel 18 and along the sides thereof. There is established between said sidewalls 41-44 a first, magnetic field and a second, stronger field to orient and suspend the articles 12 in bin 40. However, the field between arm sections 43-44 is established substantially within the periphery of wheel 18 and such field includes the stronger second field located in a specific region of arm sections 43-44. For loading articles 12 into continuously occurring vacant positions 31 which are advanced in an ascendent path, the stronger second field is located in a lower region of arm sections 43-44. For a difficult make-up function, articles 12 are introduced into randomly occurring vacant positions 31 as such are advanced in a descendent path. A bin 80 also has a strong second magnetic field located within the periphery of wheel 18; however, such field is confined to an upper region of arm sections 83-84 and there is a non-magnetic lower region to avoid downwardly attracting articles 12. In a taping operation, means are employed to machine sense all diodes, to machine eject unacceptable diodes 13 and to machine count all diodes and positions 31. Input is made to a microprocessor which determines the exact time to control various functions on a substantially automatic basis.

Introducing elongated magnetic articles into vacant positions on a

Elongated magnetic articles 12 are transferred directly from a magnetic bin 17 and transported on a member 80 having deep slots 84 to retain the articles 12 for treatment. In a preferred example, the articles 12 include some articles 13 having undesirably shaped leads 14 and the treatment comprises lead straightening. A system of magnets 30 generates a magnetic field in the bin 17 which suspends and orients a supply of the articles 12 and 13 such that a dense, rotating pattern of articles is formed and urged against member 80. A pair of supports 57 and 58 limit the depth of the slots 84 at a first level to prevent more than one article 12 or 13 to enter therein. As an entered article 12 or 13 advances beyond the supply of articles, the supports 57 and 58 are discontinued and the entered article moves to a second level. Portions of the magnets in the bin 17 are advantageously extended, without discontinuities, along the edges of the transport area to form a system of magnets 34 which communicates from end to end of the articles 12 and 13 as they are advanced along the first and second levels. A system of magnets 70 generates a magnetic field directed inwardly of the slots 84 to attract the articles 12 and 13 to the first level and another system of magnets 55 generates a magnetic field transversely of member 80 to stabilize the articles in the slots 84. System 70 also generates a series of inwardly directed magnetic fields to attract the articles 12 and 13 and to retain them at the second level until they reach the treatment area.

Transferring and transporting elongated magnetic articles for treatment

Elongated articles (13), having an undesirable shape caused by a bent lead (14), are distinguished from elongated articles (12) which are desirably straight. The bent articles (13) are separated from a mass of articles (12 and 13), most of which are substantially straight. The articles (12 and 13) are typically axially leaded diodes having leads (14) which are magnetic. Such diodes (12 and 13) are successively introduced between sidewalls (11 and 22) of a bin (17) having a magnetic field which orients each article transverse to guide members (28 and 29) extending lengthwise of the bin (17). Each oriented diode (12 and 13) presents a distinctive configuration according to its shape when viewed against a plane transverse to the guide members (28 and 29). The major portion of a bent diode (13) will be disposed lower than the major portion of a straight diode (12). The diodes (12 and 13 ) are advanced in succession along the guide members (28 and 29) and the configurations of the diodes (12 and 13) form substantially parallel pathways through the bin (17). An interposing and separating mechanism (34) is located in the bin (17) adjacent to the pathways of the diodes (12 and 13). The mechanism (34) interposes at least one member (32) between the pathway of a diode (12) which is substantially straight and the pathway of a diode (13) which is unacceptably bent. The bent diode (13) strikes the interposed member (32) and becomes disoriented in the magnetic field of the bin (17). The bent diode (13) falls away from the guide members (28 and 29) and is drawn downwardly through an exit port (18) into an exit chute (44) which has a magnetic field to orient the diode (13). The straight didode (12) passes over the interposing member (32) and continues to advance along the guide members (28 and 29) to an outlet end (21) of the bin (17).
