MURRAY N. LEVY NAVI BY MENASHE PAIENIED Jul 1 2 FIG. 6

SHEEI '6 0f 5 INVENTORS. MURRAY N. LEVY BY MENASHE NAVI ARTICLE CONTROLLED BOTTOM MARKING APPARATUS BACKGROUND OF THE INVENTION This invention relates to printing apparatus for imprinting the bottom surface of containers and the like.

In practice, it is frequently desired to imprint the bottom surface of a container or the like with a coded identification, which may represent the date of processing, the batch from which the contents were taken, the machine upon which processing was accomplished, or any desired information. As used herein, bottom surface, is not limited to the actual bottom surface of the container or the like, but rather, includes any surface of the container or the like which is the lowermost surface when the container or the like is processed by the apparatus according to the invention.

In the art, such bottom marking has been achieved by such diverse means as hand stamping and machines incorporating a lead screw which propels the object to be imprinted past the printing means, while maintaining successive objects in a predetermined spaced relation so as to insure registration of the imprinting with the bottom of each object. The prior art arrangements have been found to be inflexible, complex and unduly expensive. Thus, in the case of the devices provided with a lead screw, the lead screw must be changed if an object of a different size is to be imprinted, a time consuming process. Further, such devices are severely limited in the shape of the objects which can be processed thereby.

By providing a bottom marking apparatus wherein the objects to be imprinted are propelled by a pair of spaced moving belt means, and flexographic printing is effected in response to a sensing means in the path of the object, which sensing means is selectively displaceable along said path, the foregoing disadvantages in the prior art arrangements are avoided.

SUMMARY OF THE INVENTION Generally speaking, in accordance with the invention, an apparatus for imprinting on the bottom surface of a plurality of objects carried along a path is provided including a pair of spaced moving belt means in said path for carrying said objects along a portion of said path. Sensing means are disposed in said portion of said path for producing a detection signal when each object to be imprinted passes thereby. Print means is positioned below and intermediate said pair of moving belt means and adapted for actuation in response to said detection signal to effect imprinting on the bottom surface of the detected object. Drive means are provided for driving said moving belt means and said print means. Means are provided for selectively displacing said sensing means along said portion of said path for positioning said imprinting on said bottom surface.

Means may be provided for laterally displacing said pair of spaced moving belt means for selectively adjusting the space therebetween. The height of each of said pair of moving belt means relative to said print means may also be adjustable. Cabinet means may be provided for carrying said print means and drive means, said pair of spaced moying belt means being mounted on the top surface of said cabinet means and projecting beyond the sides thereof for cooperation with infeed and take-away conveyor means. The objects to be imprinted may be carried solely by said pair of spaced conveyor means, or may be conveyed along the top surface of said cabinet means.

Said print means may include frame means on which are mounted a rotatable die wheel means and inking means. Means may be provided for resiliently pivotably mounting said frame means so that said frame means is displaceable in response to the engagement of said die wheel against regions of irregular elevation on the bottom surface of the object to be imprinted. Said print means may include a drive shaft positioned on the axis of pivoting of said frame means and means operatively coupling said drive means to said drive shaft and said drive shaft to said die wheel means and inking means. The means for operatively connecting the drive shaft and inking means may be adapted for continuously rotating said inking means. The means operatively interconnecting said drive shaft and said die wheel means may include clutch means for selectively operatively coupling said die wheel means to said drive shaft in response to said detection signal for rotating said die wheel through one cycle to effect printing on the detected object.

Said die wheel means may be formed from a pair of radially projecting arms and a die means mounted on the end of each of said arms. Said inking means may include an inkwell, an ink roll projecting into said inkwell, and a metering roll engaging said ink roll. Said die wheel means is adapted to rotate during each cycle, first engaging said metering roll to receive ink therefrom, and then engaging the bottom surface of the object to be imprinted to effect imprinting.

The means for pivotably mounting said print means may also permit the lateral displacement thereof for positioning of said die wheel means laterally in the space between said pair of moving belt means. Said drive means and moving belt means and print means may be operatively connected by flexible shaft means.

Accordingly, it is an object of this invention to provide a bottom marking apparatus which imprints a plurality of successive objects in response to detection of each of said objects.

A further object of the invention is to provide a bottom marking apparatus adapted to accommodate objects of a wide range of sizes and shapes, and to imprint on the bottom surfaces of such objects, irrespective of the irregular elevation of said bottom surfaces.

Still another object of the invention is to provide a bottom coding apparatus which incorporates flexographic printing techniques to imprint on a plurality of successive objects.

Still other objects and advantages of the invention will in part be obvious and will in part be apparent from the specification.

The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts which will be exemplified in the constructions hereinafter set forth, and the scope of the invention will be indicated in the claims.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to FIGS. 1 3, marking apparatus 10 depicted in the drawings is positioned between an infeed conveyor 12 and a take-away conveyor 14 in the path of a plurality of objects such as containers 16. Said containers are carried in the direction of arrows 18 and are fed to the bottom marking apparatus 10 by infeed conveyor 12 and carried away therefrom by take-away conveyor 14.

Bottom marking apparatus 10 is formed with a cabinet 20 within which is mounted a drive assembly 22 and a print assembly 24 (FIG. 3). A conveyor assembly 26 is mounted on top of cabinet 20 in the path of containers 16.

Conveyor assembly 26 consists of a pair of laterally spaced substantially parallel moving belt means, each of which consists of an endless belt 28 respectively rotatably mounted on a pair of rollers 30, which in turn are mounted by shafts 32 to a belt housing 34. Each of belt housings 34 are supported on a pair of longitudinally spaced lead screws 36 and 38. As best shown in FIG. 3, said lead screws are journaled through each belt housing 34 so that said lead screws may rotate relative to said belt housing while supporting said belt housing. Lead screws 36 and 38 are ganged together by means of pulleys 40 and 42 mounted respectively on lead screws 36 and 38 and a chain 44 joining said pulley. Each of lead screws 36 and 38 pass through correspondingly threaded apertures in vertically fixed blocks 46 and 48. Said blocks are in turn mounted on lead screws 50 and 52, as more particularly shown in FIG. 2. Lead screw 38 is formed with a projecting portion 54 of square cross section adapted to removably receive a handle such as handle 56 shown in dashed lines in Fig.3. Said handle provides means for rotating lead screws 36 and 38 for selectively raising and lowering each endless belt 28 and belt housing 34 relative to the vertically fixed blocks 46 and 48. The conveyor assembly is shown in phantom lines in a raised position in FIG. 3.

Referring now to FIG. 2, it is noted that lead screws 50 and 52 are mounted on cabinet 20 so that they may rotate relative thereto in response to a handle 58 removably mounted on a squared projecting portion 60 of lead screw 52. Lead screws 50 and 52 are ganged together for coordinate rotation by means of pulleys 62 and 64 mounted respectively on lead screws 50 and 52,

along lines which pulleys arejoined by a chain 66. The threaded apertures in the two sets of blocks 46 and 48 associated with each endless belt 28 are threaded in a direction such that, upon the rotation of handle 58, the spacing between endless belts 28 may be selectively adjusted. FIG. 2 shows said endless belts in phantom lines in an expanded position engaging in enlarged containerl6.

As best shown in FIGS. 2 and 3, each endless belt 28 is driven through a drive shaft 68 rotatably mounted on belt housing 34 and having a pulley 70 mounted thereon. Pulleys 70 are joined by chains 72 to pulleys 74 mounted on one of shafts 32, for the transmission of the rotation of drive shafts 68 to endless belts 28.

Drive assembly 22 includes a variable speed motor 76 controlled by a speed control 78. Said variable speed motor is operatively connected to each of the two drive shafts 68 by separate flexible drive shafts 80, which in turn are driven through gear train 82, which gear train is directly driven by motor 76. The use of flexible drive shafts permits the ready adjustment of the positioning of the conveyor assembly without concern for disconnecting or otherwise realigning the drive arrangement. From the foregoing, it is apparent that the conveyor assembly is particularly adapted to be readily set to receive objects of a wide range of sizes and shapes. The ends of the conveyor assembly project beyond the sides 84 of cabinet 20, thereby eliminating the necessity of any special interface surfaces or devices intermediate the intake and take-away conveyors and the bottom marking apparatus according to the invention. The foregoing arrangement also permits the grasping of the object to be imprinted by the endless belts, so that the bottom of said objects need not be in engagement with the top surface of cabinet 20, thereby minimizing the possibility of tipping of the containers due to friction, or the wear of said top surface. The arrangement of the endless belts also tend to urge objects to be imprinted into the belt gap even if they are an inch or so off center.

Each of belt housings 34 are formed with a longitudinal slot 84 for mounting the sensing arrangement according to the invention. Said sensing arrangement consists of a light source 86 connected to a source of power by means of electrical cable 88, and a receiver I 90 connected to a control means by means of electrical cable 92 (FIG. 2). One of said light source and receiver is mounted on each of said belt housings by means of bolts 94. which extend through slot 84. A scale 95 is provided adjacent each slot to permit the coordinated adjustment of both the light source and the receiver.

Said light source and receiver are positioned in.

which detection of a container 16 occurs may be selectively controlled.

Referring now to FIGS. 3 6, it is seen that the print assembly 24 is pivotably mounted on a bracket 96, which in turn is secured to a cross bar 98 (FIGS. 3, 4 and 6), which cross bar is mounted within cabinet 20. Cross bar 98 extends laterally of the path of container 16, and as best shown in FIGS. 4 and 6, is provided with a longitudinally extending slot through which mounting bolt 102 extends for securing bracket 96 to said cross bar. A pin 104 also projects from bracket 96 into slot 100 for supporting said bracket. By loosening bolt 102,it is possible to laterally displace all of print assembly 24 relative to the path of the containers for positioning of the desired imprinting on the bottom surface of said containers.

Bracket 96 is provided with a pair of arms 106 having aligned apertures 108 therethrough. A bearing 110 is received within each of said apertures for rotatably supporting a print drive shaft 112. Said print drive shaft is operatively coupled to drive assembly 22 through a flexible cable 114 which engages one end of said shaft. Fixed to said shaft by set screw 115 for rotation therewith is a driving gear 116. A drive housing 118 is also mounted on said shaft through bearings 120 which perpin 126 to print housing 118. Said threaded rod passes through an aperture 128 in bracket 96 and is retained by a knob 130 formed with a threaded aperture through which said threaded rod extends. A spring 132 is mounted intermediate a washer 134 and nuts 136 to normally bias print housing 118 so that it is positioned in the extreme counter clockwise position as viewed in FIG. 4. When a downward pressure is applied on the print assembly, as described below, said print housing will pivot in the clockwise direction as viewed in FIG. 4, against the bias of spring 132, and will be returned to its original position upon release of the pressure, due to the action of said spring. Aperture 128 is sufficiently wide to permit the skewing of rod 122 during the pivoting of print housing 118.

By the foregoing arrangement, the print assembly is pivotable without interferring with the transmission of drive to said print assembly, since the axis of pivoting is defined by the print drive shaft. The rotative force of said drive shaft is transmitted through driving gear 116, to idler gear 138, which is mounted on shaft 140 to print housing 118. Said idler gear is operatively coupled to a first inking roll gear 142 which is joined to a second inking roll gear 144 for driving inking roll 146. Said first and second inking gears and said inking roll are all mounted for free rotation on inking shaft 148 through bearings 151. These parts are retained on the inking shaft by means of a cap screw 153 secured to one end of said shaft. Inking shaft 148 extends through print housing 118, the portion 150 thereof being eccentrically mounted within said print housing. The shaft is retained in position by means of a sleeve 152 and a cap screw 154. When cap screw 154 is released, shaft 148 may be rotated by rotating sleeve 152, which is coupled to said shaft by a set screw 156, to adjust the position of the axis of rotation of inking roll 146, for purposes which will be described below.

As shown in FIG. 5, inking roller 146 projects into an inkwell 158 which is mounted on print housing 118 by a rod 160, the end of which is threaded for engagement with a corresponding aperture 162 in the base of inkwell 158. Rod extends through an aperture in print housing 118 and is formed with a knob. 164 at the end thereof to permit easy removal of inkwell 158. A lock washer 166 is mounted on rod 160 adjacent the threaded portion thereof, so that said rod is retained in the print housing when the inkwell is removed. The ink is retained between walls 168 and 170 of the inkwell, and is fed thereto from a bottle 172 through a tube 174 (FIG. 1). This continuous feeding arrangement insures a constant desired level of ink in the inkwell during printing. Second inking gear 144 operatively engages with a metering gear 176 which is coupled to a metering roll 178, said metering roll and metering gear being freely rotatable on a metering shaft 180 formed substantially identically to inking shaft 148.

Thus, metering shaft 180 is formed with an eccentric portion 182 which extends through print housing 118 and is locked in position by a sleeve 184 and a cap screw 186, said sleeve being secured to said shaft by a set screw 188. The eccentric adjusting means for metering roll 178 and inking roll 146 permits the relative displacement of said metering and ink rolls. In this manner, said rolls can be set in and out of engagement, and the degree of engagement can also be strictly regulated. Ink roll 146 is adapted to pick up ink from inkwell 158, while metering roll 178, the surface of which is textured, is adapted to pick up a measured thin layer of ink from said ink roll. The nature of the ink is such that it quickly dries when exposed to the air, and accordingly, both the ink and metering rollers are continuously rotated to prevent the drying of the ink thereon.

Referring again to FIG. 6, the first inking gear 142 is operatively engaged with a second idler gear fixedly mounted on a idler shaft 192 which is journaled through a bearing 194 mounted within print housing 118. A third idler gear 196 is fixedly mounted to the other end of said idler shaft and is in operative engagement with a die wheel gear 198. Said die wheel gear is mounted for free rotation on a bearing 200, which in turn is fixed on a die wheel shaft 202. Said die wheel shaft is journaled through bearing 204 in print housing 118, and carries at one end thereof, a die wheel 206. Die wheel gear 198 is coupled to die wheel shaft 202 through a solenoid actuated clutch 208. Said solenoid actuated clutch permits the free rotation of die wheel gear 198 in response to the rotation of the drive shaft 114 through the gear train described above, while normally preventing the rotation of die wheel shaft 202 and die wheel 206.

Solenoid clutch means 208 is operated in response to the detection signal generated by receiver 90 as more particularly shown in FIG. 8. Specifically, when a container .16 cuts the beam of light 210 between light source 86 and receiver 90, a detection signal is passed along line 92 from receiver 90 to a control means 214, which in turn is operatively coupled to the solenoid coil of clutch means 208 through line 216 to actuate said coil in response to said detection signal. When the coil of clutch means 208 is actuated, die wheel shaft 202 is operatively coupled to die wheel gear 198 so that the die wheel 206 is rotated in response to the rotation of drive shaft 112. Such rotation is limited to an incre mental distance, since the coil of clutch means 208 is only momentarily actuated, and the clutch is provided with stops engaged by the armature of the solenoid so that the die wheel 206 rotates only an incremental distance, 180 in the embodiment of the drawings.

Die wheel 206 is in the form of a pair of radially extending arms having dies 218 mounted in grooves 220 in the ends thereof. As shown in FIG. 7, the rest position of die wheel 206 is with the dies out of engagement with metering roll 178. lnk roll 146 is continuously rotating in the direction of arrow 222, while metering roll 178 is continuously rotating in the direction of arrow 224. When a detection signal is transmitted by receiver 90 in response to the proper positioning of a container 16, clutch means 208 is released, and the die wheel 206 rotates in the direction of arrow 226. Simultaneously,

the container 16 is carried in the direction of arrow 228 into the path of the die wheel. Die wheel 218 rotates so that die means 218 first engages metering roll 178 to transfer ink to said die means, and then engages the bottom surface 230 of can 16 to imprint on said bottom surface. The shape of the die wheel permits the imprinting on a concave or other recessed bottom surface, as shown in FIG. 7. The die wheel returns to a rest position at which the die means 218 assumes a position just passed the point of imprinting, while the other die means is positioned adjacent metering roll 178 for the next imprinting. A slot 231 is formed in the top surface of the cabinet to permit the arms of die wheel 206 to extend therethrough. The flexographic inks preferably used in this process promptly dry and a permanent marking has been achieved. The die means 218 may take any desired shape, including numerical, alphabetical and other indicia. The rest position of die wheel 206, between each 180 cycle, is also chosen so that the arm nearest the top surface 232 of cabinet 20' is below said top surface so as not to interfere with the containers being carried thereby by the conveyor assembly. While the embodiment of the bottom marking apparatus according to the invention is designed for a 180 rtation cycle of die wheel 206, said apparatus could also be designed for other incremental rotation cycles including but not limited to 360 and 90.

Referring again to FIG. 6, a plate 234 is mounted by bolt 236 to print housing 118 for carrying the solenoid coil of the clutch means.

It will thus be seen that the objects set forth above, and those made apparent from the preceding description, are efficiently attained and, since certain changes may be made in the above constructions without departing from the spirit and scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
