(Cl. 101-11) This invention relates to apparatus for marking articles and more particularly to an apparatus for branding pigmented indicia onto thermoplastic protector sleeves on electrical resistors to indicate the resistance values thereof.
An object of the present invention is to provide a new and improved machine for marking articles.
Another object of the invention is to provide a machine for automatically feeding articles having thermoplastic protective sleeves thereon and for branding pigmented indicia onto the sleeves.
An apparatus illustrating certain features of the invention may include a hopper for feeding individual resistors into the trailing open ends of successive pairs of arcuate slots in a pair of flanges on a feed wheel which carries the resistors into engagement with a pigment coated tape on a heated branding die and which rolls the resistors over and presses them against the tape and the heated die to effect the branding of pigmented code marks into the thermoplastic protective sleeves on the resistors which then roll out of the slots and drop from the feed wheel as the slots travel upwardly. Driven feed rolls pull the tape at a uniform velocity and a yieldably mounted roller deflects the tape to form a taut loop therein between the feed rolls and the branding element whereby when the tape is temporarily gripped between the branding die and a resistor being branded and the loop is shortened thereby, the yieldable roller is moved by the loop as the loop is being shortened and then reforms the loop after the branded resistor releases the tape.

FIG. 12 is an electrical diagram of the motor control for the apparatus.
The present branding apparatus 18 is designed to im- Patented Aug. 1, 1961 ice press code marks or numbers 20 (FIG. 1) on thermoplastic protective sleeves 22 of resistors 24 to indicate the resistance values thereof. The resistors 24 are of the type having a ceramic rod with a spiral stripe of carbon thereon to which terminal caps are connected with leads 29 extending axially therefrom on opposite ends of the resistor. The code mark 20 is formed by branding a pigment into the thermoplastic sleeve 22.
The apparatus 18 generally comprises a hopper 30 (FIGS. 3 and 4) for receiving and holding a supply of the resistors 24 and guiding them through a predetermined path into engagement with a pair of flanges 32 of a rotary feed wheel 34 and for feeding individual resistors 24 into the trailing open ends 35 of successive pairs of aligned arcuate slots 36 in the flanges for movement with the wheel 34 into engagement with a heated branding element or die 38 (FIGS. 3 and 7) positioned below the feed wheel 34. A tape 40 (FIG. 2) comprising a web of plastic material 41 having a coating 42 of dry pigment thereon is positioned over the branding die with the pigment coating uppermost and as the resistor 24 is carried into engagement with the tape on the branding die it is rolled over the tape and the die by the feed wheel 34 and pressed tightly thereagainst by a layer of resilient material 44 on the rim 45 of the feed wheel during which rolling movement of the resistor 24 on the die 38, the code mark 20 is branded onto the sleeve 22. As the feed Wheel 34 continues rotating the resistor 24 rolls out of the slots 36 and drops from the feed wheel.
The hopper 30 is supported on the upper end of a pair of brackets 47 fixed to and extending upwardly from a base plate 48 of the apparatus. The resistors 24 in the hopper 30 are formed into a row as they pass downwardly through a narrow passageway 50 in the hopper and engage a bottom 'wall 51 which extends inwardly between the flanges 32 of the feed wheel and directs the resistors inwardly toward the wheel, whereby as the resistors pass through a discharge opening 52 in the hopper the lead wires 29 thereof engage the periphery of the flanges 32 of the feed wheel and drop into the open ends 35 of a pair of slots 36 of the feed wheel. A lip 53 on the hopper limits the movement of the row of resistors 24 to permit the positioning of only one of the resistors 24 in the open ends: 35 of each pair of the slots 36) so that as the feed wheel continues its rotation shoulders 55 on the flanges 32 of the wheel at the trailing open end of the pair of slots 36 serve to remove a single resistor from the hopper with the sleeve 22 disposed between the flanges and supported on the resilient peripheral layer 44 of the feed wheel and with the leads 29 of the resistor extending laterally from the slots 36 of the flanges of the wheel. As the slots 36 and the resistors 24 therein pass over the center of the wheel and move downwardly, the resistors roll to the leading closed ends of the slots 36. To insure that this occurs a jet of air is directed through an air pipe 57 (FIG. 1) against the resistors.
The feed wheel '34 is secured to a horizontally disposed shaft 60 which is journaled in bearing brackets 61 mounted on the base plate 48 and the base plate 48 may be supported on a suitable work bench or frame. A motor 62 and gear reducer drive unit 63 are pivotally mounted at 64 on the base plate 48 and are connected through a pulley and belt drive connection 65 to the shaft 60 for driving the feed wheel 34 in a clockwise direction as viewed in FIG. 1.
The branding die 38 (FIG. 9) is in the form of a rectangular slug having the predetermined indicia impressing embossments on the upper end thereof and may be made from individual printer types bonded together. A chase 69 has a recess for receiving the branding element 38 which is locked therein by means of an eccentric 70 and the chase has an annular shoulder or flange 71 and a threaded lower end 72 which is screwed into an electrical heating rod or element 73 (FIG. 10) for heating the branding die. The heating rod 73 as shown herein is shown in the form of a commercial soldering iron unit with the tip removed therefrom. The branding die 38 and the chase 69 fit into apertures 76 and 77 in a supporting block '78 (FIGS. 7, 8, and 10) on the base plate 48 and is clamped with the flange 71 in engagement with the lower surface thereof by an annular member 79 which is screwed into a threaded opening 80 in the base plate. The annular member 79 has a flange 81 formed thereon to which is secured a guard 82 for the heating element 73.
The supporting block 78 is removably secured to the base plate 48 and comprises a flat horizontally disposed plate 85 and a member 86 extending upwardly therefrom along the centerline thereof. Plates 88 and shims 89 secured by screws 90 to the upper and lower sides of the plate 85 along opposite edges thereof are adapted to slidably engage in a slideway formed by the base plate 48 and of a pair of guide members 91 secured thereto by screws 92 (FIG. 6). A pin 93 on the base plate 48 engages the end of the supporting block 7 8 to stop it in a predetermined position to support it and the branding die 38 beneath and in vertical alignment with the center of the feed wheel 34. A pair of horizontally disposed tracks 96 is formed on the upper portion of the member 86 with the upper surface of the tracks disposed slightly below the upper embossed surface of the branding die 38 for supporting the cylindrical resistors 24 for horizontal rolling movement along a portion thereof as the resistors are rolled into engagement with the branding die by the feed wheel 34 during the branding operation. A handle 98 is formed on the block 86 by means of which the supporting block 78 may be removed from the apparatus after the branding die 38 has been removed therefrom, and the block 86 has guide slots 99 formed therein for guiding the tape 40. The position of the upper face of the branding die 38 may be adjusted relative to the feed Wheel 34 by removing the supporting block 78 and changing the shims 89 from one side of the plate 85 to the other.
A supply roll of the tape 40 is suitably supported on or near the apparatus and the tape therefrom passes around a guide rod 103 (FIG. 3) against which it is pressed by a tension device 104. The tape 40 is directed under a pin 105 (FIG. 7) in the supporting block 78, over the branding die '38, under a movable roller 106, onto a guide plate 107 and between a pair of feed rolls 108, 109. The feed rolls 108, 109 which have meshing teeth or positively gripping and feeding the tape are rotatably supported in bearing brackets 110 mounted on the base plate 48, and the upper feed roll 108 has a shaft 111 extending from opposite ends thereof on which is rotatably mounted a pulley 112. This pulley is connected by a belt 113 (FIG. 4) to a pulley 114 on the drive shaft 60 and for driving it, and the pulley 112 (FIG. is connected to the shaft 111 through a one-way clutch 116 to drive the rolls 108 and 109 in one direction to feed the tape 40 and to permit manual rotation of the feed rolls when the drive shaft 60 is not rotating. A hand wheel 118 is fixed to the other end of the shaft 111 and may be manually turned to rotate the feed rolls 108 and 109 for threading the tape 40 between the feed rolls.
The roller 106 (FIG. 7) under which the tape 40 passes is rotatably mounted in one end of a pair of arms 119 which are pivoted at their other ends of a pin 120 mounted in the brackets 110. A coil spring 121 stresses the arms 119 in a clockwise direction as viewed in FIG. 7 to a normal position in engagement with the base plate 48 to cause roller 106 to form a taut loop 122 in the tape 40 between the branding die 38 and the feed rolls 108, 109. Thus, while a resistor 24 is being rolled over the branding die 38 by the feed wheel 34 and the tape 40 is being pulled at a uniform velocity by the feed rolls 108, 109, the loop 122 formed by the roller 106 is progressively shortened and held under tension by the roller 106 until the resistor 24 is rolled off of the branding die and releases the tape at which time the roller 106 moves to its normal position, thereby increasing the length of the loop and quickly advancing the tape over the branding die 38 to present an unused portion of the tape on the die for the next branding operation.
The motor 62 is connected across a power line 123 (FIG. 12) in series with relay contacts 1241 of a relay 124 which is connected in series with a normally open start switch 125 across the power lines. The relay 124 is energized by closing the start switch 125 which closes the contact 1241 to start the motor 62, and the relay locks itself in by its contacts 124-2 which are connected in series with a microswitch 126 and a stop switch 127 which are connected across the start switch 125. The switch 126 (FIG. 3) is provided for stopping the motor 62 in the event that the supply of resistors in the hopper is depleted and it is supported on one of the brackets 47 and has an elongated curved arm 127 positioned above the feed wheel 34 between the flanges 32 thereof for engaging the resistor 24 on the feed wheel and being actuated thereby to close the switch. The arm 127, being long enough to engage a pair of resistors 24 disposed in consecutive slots 36, is held in its closed position by engagement with the resistors 24 on the feed wheel 34, and the arm 127 drops to open the switch 126 and stop the motor 63 when resistors 24 are absent from two successive slots 36 in the feed wheel 34.
Means are also provided to insure that the machine cannot be stopped while a resistor is in contact with the heated branding die 38. A normally open microswitch 131 is connected in parallel with the starting switch 125 and is suitably supported on one of the brackets 47 in a position to be actuated to closed position by cams 132 mounted on one side of the feed wheel 34 (FIG. 3). The cams 132 are arranged to actuate a switch arm 133 (FIG. 4) to close the switch 131 during the intervals that the resistors are normally being branded and in engagement with the heated branding die 38.
In the operation of the device after the apparatus has been started the resistors 24 in the hopper 30 are guided thereby individually into the open ends 35 of successive pairs of slots 36 in the feed wheel 34 and are carried thereby in a downward direction, causing the articles to move into engagement with the leading closed ends of the slots. Each of the resistors 24, in the leading ends of a pair of slots 36, is carried into engagement with the tracks 96 adjacent the branding die 38 and into engagement with the tape 40 on the branding die, and the cylindrical resistor 24 is then rolled along a portion of the track 96 and rolled over the slightly raised embossed end of the branding die 38 and the tape 40 thereon and pressed tightly thereagainst by the resilient layer 44 on the feed wheel 34 during which rolling movement of the resistor across the face of the branding die, the pigmented layer 42 of the tape 40 is heated and a pigmented code mark 20 is branded into the plastic sleeve 22 of the resistor. The resistor is then carried upwardly by the wheel and rolls down the slots 36 and drops therefrom through the open ends 35 of the slots onto an inclined plate 135 (FIG. 7) which is suitably supported on the apparatus. The resistors 24 may roll down the plate into a receptacle (not shown) or be removed by the operator.
In the event a resistor 24 does not roll out of the slots 36 and drop from the feed wheel 34 as it should, a stripper plate 136 is provided to engage such resistors and positively remove them from the feed wheel.
