((11. 156384) This invention relates to machines for feeding a label strip to a forming unit of the machine, which also applies the formed label to an intermittently rotatable table, with another unit operated simultaneously with the first named unit in printing labels applied to said table, the machine having another unit for transferring the label from the first table to a product supported on a second table and to the inclusion of a further unit to eject the labeled product from said second named table. More particularly, the invention deals with a machine of the character described, wherein both of said tables are intermittently and simultaneously rotated in bringing label and product stations in registering position with the respective units defined.

Still more particularly, the invention deals with a ma chine of the character described, wherein the printing unit has associated therewith an inking unit for inking the printing plate of the printing unit.

The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which, the separate parts are designated by suitable reference characters in each of the views and, in which:

FIG. 12 is a partial side view of the ejector unit, omitting parts of the construction; .and

FIG. 13 is an enlarged sectional detail view of a part of the table at the ejector station showing a product preparatory to ejection by the finger of the ejector unit.

In the several views and as noted in part, background showings have, for the most part, been omitted, as well as supporting frames for the shafts or other parts ofthe machine in order to simplify the illustration and no specific showings of the motor drive and intermittent drives of the tables are illustrated, as such drives will be understood by those skilled in the art.

Considering the diagrammatic showing of FIG. 2 of the drawing, it will appear that the machine comprises two intermittently rotatable tables 10 and 11. Associated with the table 10 is a label forming and applying unit 12 and a printing unit 13. Operating in conjunction with the unit 12 is a label strip delivery guide and feeding mechanism, generally identified as the delivery 14, the guide 15 and feed 16 in FIG. 1 of the drawing. At 17, in FIGS. 2, 5, 6, 8 and 9, is shown the inking unit. At 18, FIGS. 2, 10 and 11, is shown, at least in part, the label transfer unit of the machine and at 19, FIGS. 2, 4, 10 and 12, is shown at least in part, the product ejector unit of the machine.

The tables 10 and 11 are intermittently rotated by any suitable means in the base of the machine and such means is not shown. This intermittent rotation brings label stations 20 on the table 10 and product stations 21 on table 11 in registration with the respective unit, as will be apparent from a consideration of FIG. 2. In other words, the units '12 and 13 are registered with the stations 20, unit 18 with stations 20-21 and unit 19 with stations 21. The labels are formed and applied to the table 10 by unit 12 and then printed by unit 13. The printed labels are then transferred from the table 10 by transfer unit 18 to products at stations 21 on the table 11. Finally, the labeled products are ejected from stations 21 by ejector unit 19. Stations 21 are definitely formed in the table 11 by mounting product supporting sleeves 22 in apertures 23 in the table 11. One of the stations 21 is shown in sectional detail in FIG. 13. Each of the sleeves has a flange 22' at its upper end engaged by the undercut rim of a disc 24 fixed to 11 by screws, as at 25. The lower ends of the sleeves 22 have stop shoulders 26 checking downward movement of a product 27. The product 27 shown is in the form of a plastic lipstick case.

Beneath the table 10 is a supplemental and suitably heated table 10', note FIGS. 1 and 5, to heat table 10. The label strip 28, from a spool 29 of the delivery 14, has an adhesive on one surface thereof, so that, when the labels 30 are cut and applied to table 10 at the unit 12, the heat of 10 will temporarily position the labels on the face of 10 in forming the aforesaid stations 20, as seen, in part, in FIGS. 2 and 10. Suitable adjustments are provided at '12 and 13', note FIG. 5, to adjust

units

12, 13 with respect to each other, as well as to synchronize with the unit 18.

Considering FIGS. 1, 2 and 5, it will appear that a frame 31 is supported on rods extending upwardly from the top of the base of the machine. Part of these rods is shown at 32 in FIGS. 2 and 5 and, in FIG. 1, a part of the top of the base is indicated at 33. Fixed to 31 is an upstanding bracket 34 having laterally extending

arms

35, 36, note FIGS. 1 and 5. Fixed to the arm 35 is a shaft 37 having

adjustable collars

38 and 39, FIG. 5, for alining the spool 29 of the delivery 14. A spring 40 tensionally supports 29 on the face of 38 and at 41 is shown a screw in collar 39 engaging shaft 37 in adjusting tension of the spring 40.

Mounted in bracket 34 and arm 36 are

guide rollers

42, 43, FIG. 1, over which strip 28 passes. The strip 28 passes over

other guide rollers

44 and 45 suitably supported in side arms 46 pivoted and adjustable on a housing 47 of the unit 12, as diagrammatically seen in FIG. 1 and shown, in part, in FIG. 2. This structure forms the guide mechanism 15.

Secured to the housing 47 by a semi-circular clamp 48, FIG. 1, is a cylinder 49 pinned against rotation, as seen at 50, FIG. 5. The lower end of the cylinder 49 has a guide channel 51 for the strip 28. Fixed to the lower surface of the cylinder is a label guide plate 52 which also forms a guide for the punch 53 of unit 12. In the punch is a spring supported pin 54 to fix the cut label 30 to the surface of the heated table 10. The punch 53 has a head 55 which operates in the cylinder 49 and a spring 56 normally supports the punch in raised position. Mounted in the upper end of housing 47 is a supplemental cylinder 57 keyed to 47, as at 58. Mounted in 57 is a plunger 59 having a pin 60 fixed to the punch 53. Arranged in the plunger 59 is a spring 61 seating on a button 62 movable in a ring 63 mounted on 57, as shown in FIG. 5.

Mounted in spaced bearings 64 on the frame 31, note FIG. 2, is a pivot pin 65, FIG. 1 for a yoke frame or element 66. In lateral end extensions 67 of 66 are adjustably mounted

rollers

68 and 69 for actuating

units

12 and 13, respectively, note FIGS. 1 and 5. No detail showing of these rollers is illustrated in FIG. 2. Most of the showings in FIG. 2 are purely diagrammatic, as this figure is simply to generally associate the respective units and mechanism. Pivoted to the yoke frame 66 on rod 70 is an operating link 71, which extends into the base through an aperture in 33, as at 33', FIG. 1. At this time, it will be understood that both

units

12 and 13 are simultaneously actuated through element 66 in depression of the

rollers

68 and 69 to simultaneously operate

units

12 and 13. The action of the link 71 will be later described.

Returning now to the strip feed mechanism 16, FIGS. 1 and 2, at 72 is shown the feed roller fixed to a shaft 73 mounted in an extension 74 on the frame 31, FIG. 1. Mounted on the shaft 73 is a one-way clutch lever 75, having an elongated slot 76 therein. The lever serves to intermittently rotate feed roller 72 in one direction only. Operating in the slot 76 is a pin 77, with which the upper end of a link 78, FIG. 1, is coupled, this link also extending through aperture 33 and will be later described. Supported on an arm 79 pivoted in 74 is a pressure roller 80 engaging the strip 28 wound on 72 to keep the strip taut at all times. A spring 81, shown only in FIG. 2, supports 80 in constant engagement with wound strip 28 on 72.

Now, viewing the left side of FIG. 5, at 82 is shown a housing supported in frame 31. Suitably supported in 82 is a cylinder 83, having an adjustable cap 84 at its upper end, keyed as indicated. Mounted in 83 is a plunger normally held in raised position against the adjustable cap 84 by a spring 86. Adjustment of 85 fixes the position of 85 with respect to 69. Fixed to the lower end of 85 is a bracket 87 keyed to 82 by a sliding pin 88. Sliding in the upper end of 85 is a pin 89 having a transverse key pin 90 operating in slots 91 in the threaded extension 85 on 85. A nut 92 is adjustable on 85 to check upward movement of pin 89 by a spring 93 mounted in a supplemental plunger 95 and controls tension of spring 93. A printing plate 95 is mounted on a holder including a pin 96 keyed in a lower plunger 97, as illustrated in FIG. 5. Plunger 97 has a head 98 seating on a bushing 99 in 85 to support plate 95 in flat state during the inking operation. Between the lower end of the plunger 94 and the head 98 is a steel ball 100 housed in the end of plunger 94. On the plunger 97 is a rounded bearing 101 having a universal movement in a bushing 101' mounted in the lower end of plunger 85. It will be apparent that the plate 95 has a universal engagement with the label and the spring 93 provides yieldable engagement with the label 30 being printed. In this engagement, the head 98 is moved off its seat on 99 and 95, 96, 97 and 98 may be said to comprise a universally supported printing head, free to compensate for any engagement of plate 95 with label 30 and the table 10 supporting the label.

The transfer unit 18, shown best in FIGS. 10 and 11 and, in part, in FIGS. 3, 4 and 7, comprises an arm 102 mounted on a vertical shaft 103, FIGS. 10 and 11. Supported on the base is a tubular casing, shown, in part, at 104 in FIG. 3. The casing 104 has a flanged top 105, FIG. 10, above which is a projecting bearing 106, FIGS. 10 and 11. On the bearing 106 is a projecting bracket, having spaced ears 107, in which are adjustably supported screws 108, FIG. 10. The screws operate in conjunction with a short extension 109 on the arm 102, in which is pinned a plug 110 of suitable material, against which the screws 108 operate in checking the two movements of the arm 102 for registration with the label 30 on table 10 and the product 27 on table 11.

Considering FIG. 11, it will be seen that a disc 111 is pinned to the shaft 103 and between 111 and one side of the hub portion of the arm 102 are arranged friction discs 112. Secured to the shaft 103 at one side of the arm is a clamp block 113, between which and the arm is a spring actuated disc 114 keyed to 113, as at 115. Other friction discs 116 are arranged between 114 and the other side of the arm 102. It will thus be seen that the arm 102 is frictionally driven. The block 113 is adjustable on the shaft 103 to control the frictional drive.

A cylinder or element 117 is adjustably positioned in an elongated aperture 118 in the arm 102. A spring 119 extends the cylinder 117, which extension is checked by nuts 120. A suitable coupling 121 on an air suction tube 122 is coupled with one end of the cylinder 117, note FIG. 11. On the other end of the cylinder 117 is mounted a perforated label engaging cap 123 which, in addition to picking up a printed label 30 against the action of the adhesive on the label, also yieldably pressure applies the printed label to the product 27, as diagrammatically seen in FIG. 10. The arm 102 adjustably supports on the offset terminal end thereof a fibrous or other yieldable pressure element 124. This element applies final pressure to the label on a product at an advanced station 21 on table 11, as clearly shown in FIG. 10. It will be apparent that suitable means will be employed in the machine to apply suction in the cylinder 117 in picking up a label from table 10, as well as to cut off this suction in application of the label to the product on table 11.

The means for imparting longitudinal and rotary swinging movement to the shaft 103 to move the arm 102 between tables 10 and 11 and toward and from the tables is best shown in FIGS. 3, 4 and 7. FIG. 3 shows the lower end of the casing 104 and shaft 103. A sleeve 125 has a ball bearing mounting in casing 104. A coil spring 126 is supported in the sleeve 125, this spring engaging a pin 127 in shaft 103 to normally move the shaft in support of the arm 102 in raised position to clear the tables 10 and 11. Secured t0 the shaft 103 and arranged partially within the sleeve 125 is an adjustable block 128, note FIG. 7, which, for clarity, omits the sleeve 125.

75 The block 128 has, at its end, a fork 129 supporting a rounded bearing 130 in providing universal support of the end 131 of a link 132, which imparts the rotary oscillating movement to the shaft 103 in shifting the arm 102 to its two positions over the tables and 11.

The other end of link 132 has a universal coupling, as at 133, on a pin fixed to a cam 134, as seen in FIGS. 3 and 4. Fixed to the lower end of the shaft 103 is a shaft 135, FIGS. 3 and 7, engaged by rollers 136 on the forked end 137 of a lever 138. The lever 138 is pivoted, as seen at 139, note FIGS. 3 and 7. The other end of the lever 138 supports a roller 140 operating on the periphery of the cam 134 which is mounted on a shaft 141. The shaft 141 is a drive shaft from a motor or other drive shown, in part, at 142 in FIG. 4. Fixed to the shaft 141 is a sprocket 143. Another sprocket 144 is fixed to the main cam shaft 145, FIG. 4. Both sprockets are diagram- :matically outlined for simplification and the chain engaging these sprockets is indicated by dot-dash lines at 146.

In the base of the machine are supports 147, in which are secured ball bearings 148. Note the detail showing at the left of FIG. 4. These beanings form supports for the cam shaft 145. On the shaft 145, intermediate the supports 147, are fixed

cams

149 and 150. Rotatable on a pin 151 extending between the supports 147 are

levers

152 and 153. Supported on one end 152' of lever 152 is a ball bearing roller 154 operating on cam 149. On the forked end 153' of lever 153 is a similar roller 155 operating on cam 150. Mounted in an offset end of lever 152 is a universal coupling 156 for the link 71. The other forked end 153" of lever 153 supports a universal coupling 157 for the link 78. It will thus be seen that the cam 149 operates

units

12 and 13 and the cam 150 operates the feed roller 72 of the feed mechanism 16.

The ejector unit 19 is actuated by a crank arm 158 on one end of shaft 145, FIG. 4. Adjustable in an elongated slot 159 of 158 is a link 160, pivoted at 161 to an elongated bar 162, square in cross-sectional form, as seen in FIG. 4. Also note FIG. 12. The bar 162 is slidable in a long bearing 163. The link 160 has a rotatable mounting on the adjustment, as seen at 164 in FIG. 4. In this figure, the rotation of arm 158 is indicated by the dotted line showing. The bearing 162 projects through an upper slotted disc 165 on 163 and its upper end is rounded, as seen at 166 in FIG. 12. Adjustably fixed to 166 is a radial finger 167, on which is adjustably fixed a block 168, with which is coupled up upwardly projecting pin 169, having a head end 170 of rubber or other plastic material. The head 170 and part of the pin 169 is shown in FIG. 13 in its normal lowered position. FIGS. 2 and 10 show the adjusted position of the finger to register with the stations 21 on the table 11. In action of the arm 158 and link 160, the pin 169 and head 170 move upwardly in the sleeves 22 simultaneously to dislodge the products 27 at the ejector station comprising the unit 19.

Fixed to the other end of shaft 145 is an arm 171, in the end of which is pivoted a channelled slide block 172, as seen at 173 in FIG. 4. Operating in the block is one end 174 of a lever 175, note FIG. 8, the other end 174 having an elongated aperture 176 therein, in which the block 172 slides. Rotation of arm 171 is indicated by the dotted line showing thereof in FIG. 4. The other end 177 of the lever 175, which is pivoted as seen at 175 in FIGS. 8 and 9, has arms 178 widely spaced by pin 177' fixed to 177. To ends of the arms 178 is pivoted the frame 179 of the inking roller 180 of the inking unit 17.

The frame 179 consists of side strips 181 joined and coupled by

rods

182 and 183 and to a shaft 184 supporting the inking roller 180, note FIG. 8. The rod 172 forms the pivot for the arms 178. In alinement with rod 183, the side strips 181 haveprojecting grooved spring supporting pins 185 and similar pins 185 are on the arm 178. Spring 186 join these pins to tension-ally hold the roller in engagement with the inking surface of an inking disc 187 of the unit 17.

The inking roller shaft 184 has free bearing mountings in strips 181 and fixed to the shaft 184, adjacent 181, are rollers 188. A sleeve 189 supports the inking roller 180 and has a set screw 189 to adjust roller 180 longitudinally of the shaft 184 to compensate for wear. Sleeve 189 can be reversed on 184.

A shaft 190 of the disc 187 has a bearing support in a part of the frame 191, shown in FIG. 8. In the frame 191 is a spring pressed pin 192 engaging disc 187 to prevent reverse movement thereof. Adjustable in sides of frame 191 are brackets 193, FIGS. 6 and 8, in which are yieldably supported projecting rollers 194, said rollers 194 being in alinement with the strips 181 of the frame 179. It will thus be seen that, as the inking roller 180 passes beneath the printing plate 95, rollers 194 will move rollers 188 into engagement with upper rails 195 adjustable in frame 31, as seen in FIG. 5, to control pressure engagement of inking roller 180 with the printing plate 95. Considering FIG. 6, it will appear that lower rails 196 on frame 191 support the frame 179 in its advancing movement. The lower surface of the forward ends of strips 181 are bevelled, as seen at 197 in FIG. 8, to guide strips 181 on rollers 194 in yieldable support of inking roller 180 in the raised inking position, indicated in dotted lines at 180 in FIG. 8. This action is against the tension of springs 186. The printing unit 13 is actuated after the frame 179 and roller 180 have been withdrawn from beneath the printing plate 95.

In the aforesaid forward inking movement of frame 179, an inwardly projecting pin 198 on one of the arms 178, see FIG. 9, strikes a downwardly directed pin 199 on a one-way clutch 200 on the shaft 190 in rotating the inking disc 187 a partial revolution to change the ink surface engaged by roller 180. This movement is against the tension of a spring 201, FIG. 6. The spring 281 serves to retain the clutch 200 in normal position, as shown in FIG. 6, when the frame 179 is retracted. This latter movement of the clutch is checked by an adjustable stop screw 202 shown in FIG. 6.

Mounted on the lever 152 is a pin 203 and another pin 204 is mounted on 147. Coupled with these pins is a spring 205, FIG. 3, which normally maintains roller '154 in constant engagement with the cam 149. At 203 is shown a pin, similar to 203, on the lever 153 and a similar spring structure, not shown, is employed to support roller 155 in engagement with cam 150, as will be apparent from a consideration of FIG. 3A.

Considering FIG. 1 of the drawing, it will appear that at the left end of guide mechanism 15 is diagrammatically shown a knife or scraper blade 206 and a wiper pad 207 to clear and clean the surface of the table 10 in advance of the uni-t 12. The blade 206, in addition to removing adhesive from the table 10, will also serve to displace unremoved labels to avoid double label applications to a product at the transfer station.

In many instances throughout the description of the several uni-ts, it will appear that reference to detail structures shown are omitted, as their function and operation will be apparent to those skilled in the art. In this manner, a lengthy specification is obviated.

The operation of the machine will be readily understood fr-om the foregoing description and the following brief statement.

At first, it will be understood in advance of the unit 18, products 27 are manually or otherwise placed in the apertures 23 of table 11 in such manner as to assure the delivery of the products to the unit 18 for reception of the labels 30. In intermittent rotation of the tables -10 and 11,

stations

20, 21 are brought simultaneously into registration with the respective spaced units 1 2, 13, 18 and 19. The strip 28 is fed or advanced and the frame 179 is advanced when the tables are rotated; whereupon, the feed of strip 28 is stopped and the frame 179 retracted so that the moment the tables 10 and 11 come to rest, all of the

units

12, 13, 18 and 19 are actuated. Unit 12 forms from the strip 28 a label of any contour and applies the labels to the heated table 10 to which the label is attached by the adhesive employed. Unit 13 prints the label, which, at the time, registers with unit 13, to form the printed label 30. Unit 18 removes label 30 from the dotted line showing at 30' in FIGS. 1 and 10 by suction through the cylinder 117 and immediately applies the label to a pro-duct on the table 11. From this standpoint, it will be apparent that the two cam surfaces on cam 134 will provide in each revolution of the shaft 141 the two downward movements contributed to the arm 102, first into engagement with table 10 and, then, to engage table 11.

In the operation of applying label to the product, in this same operation, a previously applied label is pressure pressed on a product by element 125. The unit 19 ejects a labeled product from one of the sleeves 22 at a station 21.

During the above cycle of operation defined with respect to the primary units, it will be understood that, after one label has been cut from the strip, the strip is fed an interval sufficient to provide formation of the next successive label and the inking unit 17 has been actuated to ink the printing plate, these latter operations being also performed when the tables 10 and 11 are rotated. The foregoing operations are repeated in each cycle of operation of the machine.

In the adaptation of the invention as disclosed, the stations 21 are on a second table moved in synchronism with the table 10. However, in some adaptations of the invention, these stations may be otherwise intermittently brought into registration for delivering products in position to receive labels transferred from 10 by the transfer unit 18.
