74 Claims. (Cl. 153-15) This invention pertains to the manufacture of elongate strand-like articles, of which shoe or similar tipped laces may be cited as examples, and relates more particularly to a method of and means for inspecting, transferring or conveying, and delivering such articles, whether individually or in groups, for example in pairs, such transfer and conveying means including loading and unloading devices.

For specific illustration I have here chosen to describe my invention in its application to the tipping and packaging of shoe laces. The present invention as herein disclosed is embodied in means for holding the laces in definite relative arrangement to facilitate inspection and for transferring the laces after tipping and inspection to a packaging mechanism. This transfer means comprises, among other things, a movable reservoir (or conveyor) device, preferably in the form, of a rack or holder movable individually from loading position adjacent to the tipping machine to unloading position adjacent to the packaging machine, 'such rack or holder being adapted to hold any convenient number of laces, for

1 Referring to the drawings and more particularly to Figs. 1 to 4 inclusive, the numeral 1 designates the frame of a tipping machine. This frame 1 may be provided with upstanding brackets 18 (of which but one is here shown) forming supports for two substantially parallel rails 20 constituting a guideway for a reciprocating shuttle or nipper carriage 21. The brackets 18 also support a rail arm 101.

22 which carries spaced nipper controlling devices 23 and 24. The devices 23 and 24 may be adjusted longitudinally of the rail 22 and determine by their relative positions the points at which the nipper shall seize and drop the lace material respectively. The shuttle or nipper carriage 21' is reciprocated along the rails 20 by means. of a rock arm 25 pivotally connected to the carriage 21 and actuated by any suitable means, not shown. The tipping mechanism also comprises usual tipforming dies indicated generally at D, actuated in usual manner and by usual means.

The lace material C which may be drawn from any suitable source of supply, after passing through tension devices or other accessory elements, extends over a lifter 63 on its way to the dies. This lifter is actuated at proper intervals by suitable mechanism to lift the lace material to form an upwardly extending bight C permitting the nipper 6Q on the nipper carriage to grip the lace material when the nipper carriage is in the dotted line position of Fig. 1. The nipper carriage, as shown more clearly in Fig. 2, carries a fixed jaw 69 with which the movable jaw 69 cooperates. The movable jaw has an actuating tail 70 which is adapted to engage cam devices on the members 23 and 24, whereby the movable jaw is separated from the fixed jaw at proper times to enable it to seize the lace and. then to drop it. As the nipper carriage reciprocates the jaws seize the lace of the bight C and draw it longitudinally across the dies, the length thus drawn out depending upon the point at which the arm 70 engages the releasing cam of the member 24. When the lace material has thus been drawn across the dies, the latter are actuated to form a double length tip, and the material is then severed at the mid point of this tip, thus forming a lace C having tips T and T at opposite ends, it being understood that the tip T was formed at the previous operation.

In accordance with the present invention, I provide automatic lace delivering means for delivering laces from the tipping mechanism to the transfer devices. This delivering means comprises a shaft mounted in suitablebearings upon the frame 1 of the tipping machine or upon other convenient support. This shaft carries an arm 101 which is forked at its outer end to provide parallel arms 102 and 103 (Fig. 1) Each of the arms 102 and 103 is provided with a fixed nipper jaw, 104 and 105 respectively. With these fixed jaws cooperate movable jaws 106 and 107, respectively, carried by bell crank levers pivotally mounted upon themespective arms 102 and 103. These bell crank levers are provided with arms 109 which are connected by a transverse bar 110 (Fig. 1). A connecting rod 111 is pivotally secured at one end to the bar 110, and at its other to a rock lever 112 (Fig. 2) pivoted at-112 on the A spring 113urges the rocker 112 in a counterclockwise direction, as viewed in Fig. 2,

thus tending to hold the nipper jaws open.

The rocker 112 is provided with a cam follower shoe 114 which, as the arm 101 is rocked in a counterclockwise direction, engages a relatively fixed pivoted bridge cam 115, thereby swinging the rocker so as to close the jaws and to deliver the cam follower 114 onto the top of a fixed cam dwell 116 concentric with theaxis of the shaft 100. So long as the cam follower remains in contact with the dwell 116, the nipper jaws remain closed, but when the follower drops from the lower end of the dwell 116, the jaws are opened by the spring 113. As the arm 101 then swings to the right, as viewed in Fig. 2. the cam follower 114 passes through a groove 117 beneath the dwell 116 and eventually escapes from beneath the bridge member by raising the latter. v

The shaft 100 is provided with a pinion 118 meshing, with a segmental gear 119 carried by a shaft 120. This shaft is provided with a rocker arm having a connector rod 121 secured thereto. This connecting rod is actuated in proper timed relation to the movement of the carriage 21 by means of a suitable cam B (Fig. 11) on the main cam shaft S of the tipping machine.

The frame of the machine is furnished with a forwardly projecting bracket 122 provided with bearings for a shaft 123 on which is mounted a ratchet wheel 124 to which is secured a gear 125. An arm 126 turns freely on the shaft 123 and carries a pawl 127 engaging the ratchet wheel 124. The arm 126 is rocked by means of a connecting rod 128-pivotally connected to a rock arm 129 carried by the shaft 100 and which is actuated by means of a connecting rod 129. The connecting rod 129 receives its motion from a cam 201 on a counter shaft 202, (Figs. 10 and 11). A gear 203 fast to cam 201 meshes with a pinion 204 on shaft S. As shown the gear and pinion are in such ratio that the cam 201 turns but half as fast as cam B'but cam 201 has a double throw and thus arm 101 makes one down stroke for each movement of the ratchet wheel. Equivalent means for attaining the desired results may be used. The cams B and 201 are so timed that the ratchet wheel is moved while the arm 101 is moving to the right. (Fig. 2).

The bracket 122 supports an auxiliary bracket 130 (Fig. 2) carrying spaced members 131 which support the-outer of a pair of guide rails 132 and 133 respectively (Fig. 4). These guide rails sup- .port a reciprocating carriage 134, the rails being preferably so disposed as indicated 'in Fig. 2, that the carriage moves in an inclined plane. This carriage is furnished with a toothed rack 135 on its under side which meshes with the pinion 125. The carriage 134 is of suitable width and length to accommodate a lace holdingdevieeftrhereinafter referred to as a reservoir since it functions to, receive and to store an accumulation of laces. shown in Fig. 3, the reservoir may take the form of a rack comprising as one of its essential features two spaced series of article positioning and engaging elements, for example notches 0r slots 138 in parallel bars 137, said notches being spaced at suitable and preferably equal intervals, the notches in the bars being directly opposite each other, a pair of aligned notches hereinafter being referred to as a set. Preferably the notches are inclined to the edges of the bars 137, for example at 45, so that when the reservoir is placed in the carriage, each slot, when in lace-receiving position, opens upwardly and is substantially tangent to the cylindrical surface described by the two pairs of nippers on the arm 101. In place of the notches, series of spring clips or other equivalent retaining elements may be employed for engaging and positioning thelaces, the notches if used being suificiently narrow to pinch orgrip the lace to prevent its accidental displacement or escape.

The reservoir R, comprising the spaced bars 137, may be secured in carriage 134 inany suitable way, as for example, by means of spring clips (not shown) or merely by fitting snugly within a properly dimensioned carriage. Alternatively the carriage may, if desired, be integral with the reservoir and may be moved therewith from place to place.

The delivery mechanism above described operates substantially as follows:Assuming that the tipping machine has just completed a lace C, and assuming that the nipper jaws on the arm 101 are open, and that the completed lace C lies in the path of movement of the jaws, the arm 101 is moved forwardly until the lace lies between the open nipper jaws just as the dies and the nippers on the carriage 21 release the lace. Substantially at the instant that the jaws of the arm 101 engage over the lace, the cam follower 114 engages the cam member 115, thus closing the jaws. The arm 101 continues its forward movement (to the left in Fig. 2) with the lace firmly clasped between its spaced sets of nipper jaws. The arms 102 and 103 are spaced further apart than the two series of lace positioning elements, and in fact far enough apart to straddle the entire Width of the reservoir. Thus when the arm 101 reaches the dotted position of Fig. 2, the straight and slightly tensioned run K of lace extending between the arms 102 and 103 is stretched across the entire width of the reservoir. The latter has been so positioned by the operation of the pawl 127 and ratchet 124 that a set of upwardly open notches 138 stands ready to receive the straight run of lace extending between the nipper jaws. At the end of the forward movement of the arm 101, the nipper jaws are opened as above described, leaving the lace in the reservoir the straight run K being maintained by engagement of the lace at spaced points inthe notches 138. As the arm 101 swings back, the reservoir is moved one step, so that at the next forward movement of the arm 101, a fresh pair or set of notches is positioned to receive a lace.

Preferably the parts are so positioned that a relatively short end of the lace, for example, that end having the tip T, hangs down from one side of the reservoir, the longer portion of the lace depending from the other side. Since the relative position of the guides 132 and 133 and the dies D is fixed, the depending short ends of the several laces are of substantially the same length.

The arm 101 andthe reservoir R continue to move as above described until each set of notches in the reservoir holds a lace. The reservoir is then removed from the carriage, the latter is returned to the upper end of its path, and an empty reservoir is mounted in the carriage. The full reservoir, with its complement of accurately spaced and positioned laces may be delivered to a means for direct carriage to a packaging or other machine, or it may be placed in storage and subsequently used as a source of supply for any later operation whether carried out by hand or mechanically. However, at some point between tipping and packaging the laces must be inspected for defects, and the spaced arrangement of the laces in the reservoir permits inspection of the entire group without disarranging the laces and much more quickly and accurately than is possible by usual methods.

Thus this mode of arranging the laces at the completion of the tipping operation is of distinct advantage since the laces in the reservoir are kept in a definite spaced relative positionso that they are not readily snarled; they are individually exposed for inspection, and they may be separated with the greatest ease and certainty for subsequent use. If desired the reservoir and delivery means may be made of such dimensions as to hold a major part of the lace in a definite position and straight and taut. Thusfor example, as shown in Fig. 15, the reservoir R, which in this instance is made of sheet metal has the parallel side walls 137 spaced apart a distance but slightly less than the length of a lace, the walls having the notches or slots 138 for the reception of the laces. As shown the end portions of the laces are received in the notches or slots 138 in the respective side walls so that the major portion of each lace forms a substantially straight run K withthe tips T hanging down outside the walls 137 While the reservoir thus above described is useful more generally, for example for inspecting laces, its ultimate purpose is to serve as a transfer device or conveyor in which the laces may be stored and eventually carried from the tipping machine to the packaging machine.

Referring now to Figs. 5, 6 and 7, the numeral 140 indicates in general the frame of a machine for performing a subsequent operation upon the tipped laces. As here illustrated this machine is adapted to package the laces in pairs. Only so much of this machine is here disclosed as is necessary to indicate its general mode of operation. Thus, as shown in Fig. 5, the packaging machine comprises a hollow shaft 43 having an elongate pinion 45\mounted thereon and carrying an elongate member 46 constituting the back of a reel. This reel comprises spaced sets of jaws, each set having jaws 47 and 48 which may be separated to admit the ends of a pair of laces between them. An intermittently driven gear 59 engages the pinion 45 and is adapted to turn the reel whereby to wind the laces upon the arms constituted by the spaced sets of jaws. The reel ceive the end of a properly positioned lace between its open jaws, and secondly to move further to a reeling position. The position of the reel is controlled by a cam Z (Fig. 12). This cam has a dwell cl adapted to hold the reel in a fully retracted position, a dwell d which holds the reel in a mid-position during reeling, and an active portion 01 which advances the reel to discharge position after reeling is complete. The machine may comprise a shaft upon which is mounted a turret comprising arms 114 etc., each of said arms being furnished with sets of coil holders 126 and 126 adapted to receive a reeled lace from the jaws of the reel and to carry such .reeled lace to suitable wrapping mechanism (not shown).

In accordance with the present invention, I

provide suitable unloading means for discharging.

laces from the transfer reservoir R and presenting them to the packaging machine, or such other machine asis to perform the next operation upon the laces. To this end I furnish the latter machine with substantially horizontal parallel guide rods 141, 142 and 143 respectively. These rods are secured in fixed relation to the machine frame in any desired manner, their outer ends being supported, if desired, in a bracket 144. The rods 141 and 142 support a reciprocating carriage 145 having a projecting pin 146 to which one end of an actuating lever 147 is connected. This lever 147 may be actuated by any suitable means, for example, a connecting rod 147 Fig. 12) operated by a cam W.

The carriage 145 is provided with a journal 148 for a rock shaft 149. This shaft carries a hub member 150 having a projecting arm 151 whose outer end 152 constitutes a fixed nipper is adapted to be moved axially so as first to re- 'stitutes a movable nipper jaw. A spring 156 tends to hold the jaw 155 in contact with the jaw 152. The hub 150 is also provided with an arm 157 having a cam follower roll 158 which engages a cam face 159 on a fixed plate 160 disposed between the bars 142 and 143. A spring 161, acting upon a pin projecting from the shaft 149, tends to hold the follower roll 158 in contact with the cam surface 159 and to swing the arm 156, when permitted to do so, in a clockwise direction as viewed in Fig. 5. The cam 159 is so shaped that when the carriage 145 is at the outer limit of its stroke, (as shown in Fig. 5) the arm 151 stands substantially at right angles to the guide rods 141 and 142, but when the carriage is at the other end of its stroke, the arm 151 is disposed in a position substantially parallel with the guide rods 141 and 142. As shown in Fig. 5 the nipper jaws 152 and 155 are disposed at substantially right angles to the length of the arm 151. Preferably these 'nipper jaws are of a length at least equal to twice the width of a lace.

The lever 154 is provided, at that end opposite the jaw 155, with a pin 162 adapted to engage a cam 163 (Fig. 14) on a bracket 163 adjustable on the rod 143. This cam 163 is mounted on a pin 163 journalled in the bracket and its free end is normally held against a stop 163 by a spring 163 the under'surface of the cam thus normally inclining downwardly and to the left (Fig. 6). As thecarriage 145 nears the end of its outward stroke, the pin 162 engages the cam 163 and is moved down, thus separating the jaws 152 and 155. When the carriage reaches the end of its stroke the pin 162 escapes from beneath the pivoted end of cam 163 and spring 156 closes the jaws. As the carriage moves back, pin 162 rides over cam 163, and the latter yields downwardly to permit free passage of pin 162.

The frame of the machine is also furnished with a bracket 165 (Fig. 6) providing bearings for a shaft 166 carrying a ratchet wheel 167, a gear wheel 168, and a rock arm 169, the latter being free to turn on the shaft and carrying a pawl 170 which engages the ratchet wheel 167. A connecting rod 171, secured to the arm 169, is actuated by suitable means, for example a cam K (Fig. 12). As shown this cam has a riser a of sufficient throw to cause wheel 167 to advance two teeth for each complete cycle of operation of the reeling mechanism, the advancer of the ratchet'wheel taking place while the carriage 145 is at an intermediate point in its stroke. Obviously equivalent means can be substituted for moving the ratchet wheel and the carriage in properly timed relation.

The bracket 165 carries an auxiliary bracket 172 which supports guide rails 173 along which a carriage 174 reciprocates. A rack 175 secured to the underside of this carriage meshes with the gear 168. This carriage 174 is of substantially the same type and construction as the carriage 134 above described and is adapted to hold the conveyor or reservoir device R. In mounting this reservoir device in the carriage 174, it is preferably arranged with its notches 138 substantially horizontal, and the jaws 152 and 155 of carriage 145 are disposed in such position, and the timing of the parts is such that when the carriage 145 nears the end of its outward stroke, the open jaws 152 and 155 pass on opposite sides of the substantially straight run K of a lace which extends between opposite notches in the spaced rails of the reservoir. Preferably the parts are so arranged and proportioned that the jaws 152 and 155 receive the grip between them two laces slmul- I taneously. As the carriage completes 1t outward movement the pin 162 escapes from the com 163. and the jaws close, thus gripping the laces between them. This action is made possible by the arrangement of the laces in accurately spaced relation in the reservoir, and is facilitated by mounting the reservoir in the inclined position described with the notches 138 horizontal which results in disposing the straight runs K of the series of laces in stepped relation, said runs being in uniformly spaced parallel planes and with the rear edge of one lace substantially below the forward edge of the next lace above it.

As the carriage now moves on its return stroke these laces, gripped between the jaws in edge to edge relation, are pulled out from the slots in the reservoir device and are moved to the right as viewed in Figs. 5 and 6, but when'the follower roll 158 engages. the slope 160 of the cam 159, the arm 151 is swung to the right until at the end of the right-hand stroke of the carriage the. jaws 152 and 155 are disposed, as shown in the dotted line position in Fig. 5. During the last part of the stroke of the carriage, the trailing portions of the laces C are caused to drag over the guide device G and when the carriage comes to a stop at the end of its stroke the short depending ends T of the laces hang directly in the path of the open jaws of the reel. The cam W which moves the. carriage 145 has a dwell d which keeps the carriage at the right-hand end of its path while the cam Z advances the reel to reeling position. During this advance of the reel, the ends T of the lace are gripped between the jaws 47 and 48 of the reel and as the latter jaws close and the reel starts to rotate the laces are dragged out from between the spring pressed jaws 152 and 155. .The operation is thus repeated until the reservoir is empty, whereupon a fresh reservoir, loaded with laces is placed in the carriage and the operation continued.

In Figs. 8, 9 and 9 I have illustrated certain features of the present invention as specifically applied to,a reservoir device of another type.

As illustrated diagrammatically in Fig. 13, the tipping machine is associated with a packaging machine in such a way as to permit both machines to be driven in accurately timed relation by means of a common drive shaft S having a drive pulley S adapted to receive a driving belt. Thus in these figures the reservoir device comprises an endless sprocket chain 6 extending from the tipping machine to the packaging machine and provided at suitable intervals with lace-holding supports or holders 7. For conven ience in loading by the means here disclosed, these holders 7 preferably comprise a base member 7 rigidly secured to the chain, and a hinged extension 7 normally disposed in a horizontal plane but capable of swinging to a substantially vertical position. The part 7 is provided with a notch 8 for the reception of laces, the notches preferably being of sufficient depth to hold two laces in edge to edge relation. As here shown the chain passes around a sprocket 181 and then about a sprocket wheel 182, the wheels 181 and 182 being spaced to provide a straight run 183 which lies in a vertical plane intermediate the vertical planes of the arms 102 and 103 of the delivery mechanism. Normally the members 7 of the lace supporting holders move insa substantially horizontal plane, but as they pass along the run 183 of the chain, they engage a cam device 184 which turns the member 7" into a substantially vertical plane as indicated at the central part of Fig. 8. In this position, the notch or slot 8 in the holder is so related to the path of movement of the nippers carried by the arms 102 and 103 of the lace delivery mechanism that the run M of lace extendingbetween the spaced nippers is placed in'the notch 8 with the end T of the lace closely adjacent to the holder and the longer trailing end of the lace hanging down on the other side of the chain. This chain f 6 is driven intermittently in any suitable manner, and may, if desired be driven at such a rate that the lace delivery arm 101 makes two down strokes while the holder member '7 dwells in receiving position, thus placing two successive laces in the recess 8 of each holder. As the chain again advances, the holder member 7 is disengaged from the cam 184 and resumes its normal horizontal position. In order to move the long depending end of the lace C to the other side of the chain, which is its proper position, I may provide any suitable means such, for example, as a rotating brush wheel 185 extending across the width of the chain in a position to brush the depending end of the lace transversely of the chain until it drops to the opposite side.

The holders 7 are moved forward intermittently and eventually reach a stationary position such that the depending ends T of the laces lie directly in the path of the advancing open jaws of the reel. In approaching this position, the long trailing ends of the laces are drawn over the guide G.
