Application May 1, 1936, Serial No. 77,403

14 Claims. (Cl. 10-169) The present invention pertains to a novel device for picking up articles out of a mass and delivering them in a desired or predetermined position to a point of assembly. The invention resides in improvements of the device forming the subject matter of my United States Patent No. 2,205,273 of December 24, 1935.

In this patent the invention is disclosed as a pick-up device for screws, the heads of the screws being utilized for the positioning and delivery operations. l In the present invention, the previously patented machine is modified for handling articles other than screws or headed members.

The invention includes a rotary collector ring for picking the articles from a mass and delivering them to a track, but thearticles nd their way to the bottom of slots in the'ring rather than hang in the slots as disclosed in the patent. In conjunction with the receiving end of the delivery go track, there is a xed guard lying over the adjacent ring slots and so mounted as to hold back all articles that do not assume a predetermined position in the ring. In other words, only those articles taking the desired delivery position are permitted to pass to the track. While many articles are barred and then returned to the mass the device is so constructed and operated that the percentage of articles passed is suiiicient for operating purposes. The collector ring and guard are so constructed and related to each other that an article will not be passed unless it lies on a given surface or unless a projection from the ring is received in an opening in the article or unless both of these requirements are fulfilled. For exr, ample, the lower edge of the guard directly above the receiving end o'f the track may be specially shaped to match and clear only an article engaged with a projection from the ring and thereby held in a given position.

4o The collector ring rotates about a xed member that closes the inner ends of the slots except at th'e trough of the delivery track. This closing is obtained by means of an edge of the xed member which is continuous with a side of the track up to its trough, to provide an unbroken riding surface. However, the xed member is rotatably adjustable to shift the point of contact between the edge and the track when various track widths are used. The invention provides a special member that maintains the desired unbroken riding surface in all adjustments of the track.

Another object of the invention is to provide for the overflow of properly positioned articles when the track is lled, for otherwise an article may pass part Way into a nearly filled track and thereby break a part of the machine. Provision for overflow is made by relieving theupper end of the track in the side thereof that is moreremote with reference to the direction of rotation of the collector ring. The length of the release lengthwise of the track is somewhat in excess of the length of a properly positioned article in the same direction.

The invention is fully disclosed by way of example in the following description and in the 10 accompanying drawings in Which- Figure 1 is a vertical section of the device;

As previously indicated, the machine described herein is a modification of the machine disclosed in my United States Patent No. 2,025,273 of De- 45 cember 24, 1935. As far as practicable, the same numerals will be used here as in the patent.

In Figures 6 and 8, the numeral 5 designates the main support or column of the machine. One end of an arm or bracket 6 carries headed 50 bolts 1 received in a key track 8 and is secured in the desired adjustment by tightening the nuts 9. To aid in adjusting the bracket 6 upward, a lug I0 is fastened to the column 5 and receives an inverted thumb screw Il engaging the bottom 55 of the member 6, as shown in Figure 6. Turning the screw in one direction raises the bracket 6 and the assembled mechanism carried directly or indirectly thereby. After the adjustment has been made. a wing nut I2 on the screw II is tightened against the bottom of the lug III.

To the outer or free end of the bracket 6 is secured a worm gear housing I3 from which extends a boss I4 in the axial direction and is disposed on that side of the bracket 6 at which the driving spindle assembly is located. Over this boss is slipped another boss I extending from a gear housing I6. The boss I5 has a lengthwise split I1 with a lug I3 at each side and a tightening bolt I3' passed through the lugs. When the bolt I3' is loose, the boss I5 with its housing I6 can be adjusted around the axes of the bosses. Tightening the bolts secures the proper adjustment.

It will be seen in Figure 1 that the housing I6 is cylindrical and on an axis perpendicular to that of the bosses, the axis of the housing sloping upward in the direction toward the spindle assembly. In this axis is mounted a fixed sleeve having one end keyed in a bearing I9 formed on the rear end wall of the housing I5. This sleeve extends some distance beyond the forward end wall I3' of the housing I6 and carries an external disk 23 .having a hub 2I rotatably mounted on the shaft I9 and extending into the housing I6.

The operation of the pick-up mechanism requires rotation of the disk 20, and the mechanism for effecting such rotation will now be described. The vertical shaft 23 shown in Figure 6, may be considered the power shaft of the machine and is supported and driven in any suitable manner, for example, as illustrated, in the previously mentioned patent; This shaft enters a bearing 25 formed on the worm gear housing I3. A horizontal counter-shaft 26 has one end mounted near the free end of the bracket 5 and, after passing axially through the housing I3 and bosses I4, I5, has its other end just entering the housing I6. Within the housing I3, the shaft 26 carries a worm gear 21 meshing with a worm 21' carried by the shaft 23 within the bearing 25. Within the housing I6, the shaft 26 carries a miter pinion 23 meshing with a miter gear 29 having a hub 36 rotatable on the xed sleeve I9 as may be seen in Figure 1. Pins 3l extend from the hub 39 into the hub 2| and cause the disk 29 to rotate with the gear 29.

The disk 20 is slightly dished, and at the concave side thereof is mounted a baille plate 32 bymeans of a hub 33 thereof fitted on the forward or upper end of sleeve I9. This end of the sleeve I9 is reduced to form a shoulder 34 between the disk 20 and plate 32, and a washer 35 is inserted between the shoulder and the plate.

A long pin 36 is mounted in the sleeve I9 and projects beyond both ends thereof. 'I'he end proj ecting beyond the hub 33 receives two clamp sections 31,and 36, to be described more fully below and is threaded at 36' to receive a clamping nut 36" for the clamp sections. The other end of the pin 36 is formed with a head 36 A bearing against the adjacent end of the sleeve I9 and having a wrench socket 36B. 'I'he last named end of the sleeve I9 is threaded at 36C to receive a cap 36D tightened against the bearing I9. 'I'he cap has an opening 36E forI entry of a wrench into the socket 36B. By turning the pin 36 with a wrench, the nut 36' is tightened against the 'clamp sections 31 and 38, the nut itself being inaccessible for tighteninbecanse of its position between the clamp sections as shown in Figure 4. A bearing washer 36F is inserted between the bearing I9' and hub 33. The elevation of the bale plate 32 on the incline of sleeve I9 may be adjusted, if necessary, by replacing the washer 35 with one of a diil'erent thickness.

To the rim of the disk 20 is detachably fastened -a collector ring 39 by means of screws III. In the face of the ring are inserted equidistant flns or blades 3S lying radially and forming slots or spaces 4I. The width of each space is slightly greater than the diagonal of the nut to be handled, as shown in Figures and 11. The formation of the slots or spaces by means of fins is merely a preferred construction, as the side walls of the slots may be formed lin the casting or machining of the collector ring if desired.

Over the outer wall of the collector ring 39 is fitted and secured a. hood 42 having a comparatively large central opening 43 so that it constitutes a receptacle or hopper for the articles to be handled, as clearly illustrated in Figures 1 and 2. 'I'he opening 43 permits replenishment of the supp1y-of articles in the receptacle and also to accommodate the delivery track presently to be described, as well as permits access to certain parts of the mechanism for assembly, adjustment and dismantling, as will be described in detail below.

'I'he clamp sections 31 and 36 areof L-shape and slotted at 44 in the 'shorter.leg, these legs being superimposed one on the other to form a U-shaped clamp and a through opening for the pin 36 as shown more clearly in Figure 4. The clamp serves to receive and support a delivery track in the form of a channel member 45, and the clamp sections are rmly secured to the track by a bolt 45 passed through the sides of the 'I'he base angle of the inner surface 55 of the conical baille plate 32 is for the most part uniform. 'I'he periphery of this plate with its extended lip 55' covers the inner ends of the slots 4I. However, the surface .55 has an abrupt step 56 on a radial line, as shown in Figures 2 and 9, changing the angle of the inner conical surface. From the bottom of the step, where the base angle is smallest, it increases gradually to the angle of the main surface 55 at the line 51 in Figure 2. The step and the deformed surface from the bottom of the step to the point where the maximum base angle is reached, are of such extent as to uncover the inner ends of slots 4I along approximately ten degrees of the collector ring circumference, as shown in Figure 2, for a purpose to be described inl detail below.

A lug-6ll projects outward from the conical surface 55 near the periphery thereof at a distance of about 45 degrees from the track in the counterrotational direction. 'Ihis member has a slot 5I formed lengthwise therein or parallel to the axis of the conical surface. A baille strip 62, of spring metal, if necessary, is held to the lug 60 by means of a bolt 63 and headed nut 63 in the slot 6I, whereby the member 62 may be adjustably secured at a desired distance from the face of the collector ring 39. The nut has a rectangular body 63" fitted in the strip 62 and in the slot so that there is no relative turning of these parts. The member 62 crosses a few of the slots 4I near the upper end of the track 45, including that slot which is directly over the upper end of the track. In this connection it is to be recalled that the collector ring ,rotates while the baiiie plate 32 and baffle 62 remain stationary.

The upper end of the track 45 is notched or recessed at 64 in the side thereof that is more remote in the direction of rotation of the collector ring. The length of this recess along the track is about one and one-half times the dimension of the article being handled, in the same direction, to permit overflow from the track to the receptacle 42 in a manner that will appear more fully hereinafter. On one of the walls of the track is attached a guard 49 overlapping the trough of the track to prevent the articles in the track from piling up one on another.

A small metal wedge-shaped member 64 is fitted and fastened against the conical surface 55 near the periphery thereof and crossing the abrupt step 56 which lies at the yapproach side of the track 45, that is, the side at which the collector ring approaches the track in its -rotation. The top of the member 65 lies close to the inner circumference of the collector ring 39, the lip 55' being interrupted to permit this position of the member 65. The side 66 of member 65 facing the track is aiinlshed surface and slopes downwardly away from the track for a purpose that will presently be described.

' Operation Figures 10 and 11 are details illustrating the operation of the machine when used for deliverlng hexagonal nuts as'shown in Figures 1 and 2. The nuts 10 which are to be transferred by the track to the point of assembly are merely thrown into the receptacle 42 through the opening 43, whereby they lie in a mass against the face of the collector ring 39 at the lower portion thereof.

The rotation of the ring 39 causes a tumbling action of the nuts so that some of them fall in various positions into the slots 4|. The nuts picked up by the ring, at least those lying flat, are prevented by the lip 55' fromfalling outof the slots while ascending. Further, these nuts cannot drop until crossing'the top of the member 65.

Beyond the member 65, the baille strip or guard 62 extends across the upper end of the track 45 for some distance and is spaced from the face of ring 39, as indicated by the numeral 50 in Figure 11, a distance greater than the thickness of the nuts and smaller than the width thereof. Con` sequently, when a nut lying flat passes the member 65, it is in a position to slide out of its slot 4 I. The trough of the track 45 is positioned to receive this emerging nut and deliver it to the point of assembly. If desired, the upper end of the track may be rounded at 61 (Figure 2) on the approach side so that the emerging nut starts its escape from the collector ring earlier by rolling on the rounded corner.

A nut that has been improperly picked up by the collector ring, such as the nut 1| (Figures 10 and 11) standing on one of its facets, rides on the 'guard 62 and cannot pass through the space 50 to the track. Consequently, it rides to the free end o f the guard, as also shown in-Figure 2, and then drops back into the hopper 42.

At the lower end of the track 65 is a suitable escapement mechanism (not shown) -for releasing the nuts at a timed rate to the point of assembly. The guard 49 prevents overlapping of nuts that may accumulate in the track. 'I'he track may become loaded until there remains at its upper end a space not large enough to receive a nut completely, whereupon a nut may drop into this space and remain partly in its slot 4|, as is the case of the nut 12 in Figure 2. This nut will be carried through the recess 64 and permitted to drop back into the hopper instead of breaking one of the blades 39.

Adiustment Different articles to be handled require different collector rings and tracks. Preferably, the proper track is provided with each collector ring. The tracks are of varying depth and width.v For the larger widths, the plate 32 may require adjustment in the counter-rotational direction to permit the step 56 to clear the approach side wall of the track. This adjustment becomes possible on loosening the nut 36".A Also, the depth of the surface between the step 56 and the line 51 is such as to accommodate various widths and depths of tracks used with particular plates 32, in the various pitch adjustments of the track in the clamp sections 31 and 38.

In keeping with the adjustments already mentioned, other adjustments in the position of the collector ring 39 may be necessary for articles of different sizes and weights. Accordingly, the rctating assembly including the disk 20 and ring 39 is adjustable in height by manipulation of the screw Il in Figure 8, and adjustable in slope by turning the boss I5 on its axis after loosening the bolt I8 as illustrated in Figure 4.

'I'he finished surface 66 of the member 65 makes contact with the adjacent wall of the track at the upper end of this surface to form a smooth continuation of the lip. 55, up to the trough of the track, thereby avoiding any crack or crevice in Iwhich the articles being handled may be caught.

The slope of the surface 66 provides for contact at the point named even in extreme adjustments of the plate 32 in the counter-rotational direction. Also, the surface 66 being machined or finished, has no projections that might be engaged by the track in extreme adjustments of the plate 32 and thereby leave a crack or crevice between the upper end of. surface 66 and the track. I'he upper end of the track, especially on the approach side, is also curved in continuation of the riding surface presented by the lip 55' and the top of the member 65.

The previously mentioned adjustability of the guard 62 in the slot 6I permits variation in the height of space 50 for articles of various thickness. The resiliency of the guard 62 permits it to yield under the action of irregular accumulations of articles in the slots above the guard, when such accumulations might otherwise break a rigid part of. the machine.

Since a separate track is preferably provided for each collector ring 39, the tracks often varying in width, the capacity of the clamp section 31 and 38 is correspondingly adjustable by virtue of the slot 44 therein. For extreme track widths, different clamping members may of course be provided. Figures 12 and 13 illustrate a modied construction for handling castle nuts and feeding them top downward to the track or chute. The slots 4IA in the face of the ring, formed by blades, fins or other walls a are slightly greater in width than half. the diagonal of the nuts being handled. The guard 62a is so spaced from the ring 39a as to clear only those nuts that have received one of the ns 40a in one of its castle slots, such as the nuts 10a. It is evident from a consideration of Figure 13 that nuts taking any other position are carried beyond the track or chute to the free end of the guard 60a from which `they return to the hopper.

Figures 14 and 15 illustrate an arrangement for handling pins or rods. The collector ring 39h has grooves Hb formed radially in its face adapted to receive the pins. A wall of each groove slopes at 2b to the face of the ring. The guard B2b is spaced from the face of the ring less than the diameter of the articles 10b being handled. Unless an article is fairly well seated in a groove, it cannot pass beneath the guard to the chute. Those lying wholly upon the face of the ring or on a slope 42h at more than a limited angle to the radius will not pass. The slope permits a greater percentage of pins to adjust themselves to proper position for transfer to the chute.

The construction shown in Figures 16 and 17 handles threaded studs 10c in the same manner that the castle nuts are handled in Figures 12 and 13. Each stud has a screw driver slot 10d in one end, and it is desired to feed the studs with this end downward. The fins d in the ring 39d are spaced apart a distance slightly more than the radius of the stud. The guard 62d is at such a distance from the face of the ring 39d as to pass only those studs that receive a iin 40d in its slot.

The applicability of the invention to the feeding of diverse shapes is illustrated in Figure 18. The article selected as an example is a sheet metal member 80 having a somewhat S-shape and designed to be used as a clip. One edge of the member is hooked at 8l, and it is desired to feed the members endwise with the hook always at the same side of the track. As in the previous construction, the lip 55' or 55e of. the stationary baille plate 32 retains the articles in the collection ring until they reach the clearance at the discharge end of the guard 62-62E.

The collector ring 39E has fins 40E hooked at 82 to engage the hook 8| of a member 80 lying in the proper position for feeding. The engagement of the hooks also prevents the member 80 from falling out of proper feeding position. In line with the track or chute, the guard 62E has an irregular lower edge 83 adapted to mesh in or match with the upper surface of a member l0 lying in the proper position for feeding. The engagement of the hooks also prevents the member 80 from falling out of proper feeding position. In line with the track or chute, the guard 62E has an irregular lower edge 83 adapted to mesh in or match with the upper surface of a member 80 lying in the proper feeding position. Otherwise, the guard 62E is spaced rather closely to the face of the ring 39E, and only those members 80 that take the desired feeding position are permitted to pass through to the track. Articles of various shapes may be transferred to the track or chute in a given desired position by shaping the lower edge of the guard directly above the track, to conform to the shape of the upper surface of a member when in the desired position, so that only the members in that position are permitted to pass beneath the guard to the track. The shaped edge 83 of the guard prevents the articles from swinging around the free end of the guard, as would be the case of this end even square.

Although specific embodiments of the invention have been illustrated and described, it will be understood that various alterations in the details of, construction may be made without departing from the scope of the invention, as indicated by the appended claims.
