Arrangement to preclude pressing

The mandrel drum I5 normally rotates in direction _f, so that each mandrel assembly 98 successively before the printing station S is brought. The position of the mandrel assemblies 98 is adjusted so that the containers C on the mandrel 47 of the printing elements of the drum assembly 14 at the -Print adequate pressure applied and put into circulation so that the entire circumference of each container C can be printed. If, in an unexpected manner, no container C is placed on a single mandrel 47, it is desirably, the mandrel 47 inwardly against the mandrel disc 81 out of the "print" position, so that you can be sure that this single rifle is definitely not is printed. To accomplish this, a print preventing arrangement is provided which includes arm 89 in FIG necessary direction moves.

The arrangement excluding printing comprises a sensor diaphragm arrangement, which is designated generally by loj and has a membrane Io4 corresponding to FIGS. 9 and 11, which the facility Ioj5 in separate departments I05 and

106 divided. Department I05 is on a line

107 connected to the vacuum port Io2 and this in turn is connected to a vacuum source in a manner to be described. The diaphragm Io4 is connected to a rod I09, which supports a hardened sleeve Ho which is received between a block 111 attached to each pivot pin 88 is solid; a plunger arm 112 is provided which is pivotally received on each pin 88. The plunger arm 112 comprises a part 112a with an opening II3, which has a rear *

. adjusting spring 114 receives the other end by a spring mounting element 115 held on the block 111. »At the end of the tappet end 112, a cam follower roller 116 is mounted, which is designed so that it rests against a stationary Nooke 117 (Pig. Io) which is on an arm II8 on the Frame member 84 is mounted in the vicinity of the circumferential path of the printing drum assembly 14.

Since each arm 48 comprises an arrangement which excludes printing, the arrangement is set in rotation in the direction £ in FIG. 1, the cam follower roller 116 on the follower arm II7 engages behind the cam II7 as shown in FIGS. 1 and Io and pivots the follower arm 112 around the pivot pin 88. If the machine is working normally and the containers C are stored on each of the mandrel pairs 47 of a special mandrel arrangement 48, the vacuum state in the line Io7 is maintained and the diaphragm Io4 comes into a position in which the diaphragm rod Ho in the position shown in Fig. 11 is arranged. In this position the plunger arm 112 pivots slightly relative to the block 111 and, when the roller 116 passes over the cam II7, the spring 114 returns the plunger arm 112 to its position. Since the plunger arm 112 is free, the position of the support arm 89 and the mandrels 47 is not changed thereupon; printing of the containers continues in the usual manner. If, however, is for some w other reason, no container C on one of the mandrels 47 is the line remains IO7 against the atmosphere open and the membrane Io4 and the rod I09 are to the right in Fig. 11 in a position between the block 111 and the Cam follower arm portion 112a moves. If the vacuum condition in the diaphragm chamber ... Io5 is released, the spring II9 pushes the rod I09 to the right in FIGS. 9 and 11, whereby the bushing Ho is positioned between the block part 112a and the block 111 112 pivoted, so prevents the bushing Ho on the rod I09

a relative movement between the parts 111 and 112 and both parts 111 and 112 are pivoted. Since the block 111 is fixed to the pin 88 by a cap screw 12o (see FIG. 12), the pin 88 is pivoted, whereby the arm 89 and the mandrels 47 are pivoted and moved in a direction 1 , as in FIGS. 8 and 9 shown, from the circumferential path ■ of the printing drum assembly 14 away.

The printing drum assembly

The drum assembly 14 is particularly shown in Figures 1, 3-15 * 14 and 15 and includes a pair of offset printing drums 121 rotatably supported on shaft 122 which are rotatable in bearings 123 on side frame members 124 in direction "l " runs. The shaft 122 is driven by a block disk 125 by means of a drive belt 126 in a manner to be described further below.

On the drums 121 are spaced around the circumference staggered high speed printing blankets - indicated generally at 127 - arranged each one color applying cloth part 128 and a trailing, lacquer-applying cloth part 129. Near every cloth 127 is a drive strip I30 (Fig. I5) of the same length provided, which is made of the same cloth material but is thicker so that it faces the opposite Spikes 47 grabs and drives. The cloths 127 are of such length relative to the peripheral speeds of the Drums 121 and the mandrel assembly 13 that each mandrel 47 preferably makes two revolutions while passing a cloth 127. During the first revolution, the drum assemblies move

While the printing drum assembly 14 and the mandrel assembly Ij5 continue to move around their axes (counterclockwise according to Fig. 1) in the same direction of rotation, paint becomes applied by the next running cloth parts 129. The engaging surfaces of the cloth portions 128 are preferred so designed in the usual way that one color never comes into contact with another color and that so there is no mixing of colors. In the machine shown, four colors are applied - and the one on The container of printed polyethylene paint is covered with a quick-drying, clear, protective polyethylene bag cover Covered. Other compatible paints and varnishes can be used, depending on on the material from which the containers to be printed are formed. The resilient cloth material used (usually natural or synthetic rubber) is of the kind that is not attacked by the paints and varnishes used will.

Inking cloth cover assemblies, indicated generally at 131, and various colored compositions on each sheet portion 128 can be seen in Figure 1 and reference numeral 1; 55 generally indicates a similar one Arrangement, however, used to apply the protective varnish to the portion 129 of each cloth 127. Because the paint Much faster than the paint can be dried or dried quickly, it becomes possible by coating the Color printing with varnish to reduce the drying time in a very considerable way and thereby considerably reduce the container, which can be treated in a certain period of time,

'To increase, varnish and paint that are used * are' immiscible in the sense that they do not mix, dissolve or attack each other. The paint is in the form of a paste with a relatively high tack number (typically 12 -j5o), while the paint is a free-flowing liquid that does not move or disturb the paint after application due to this difference in viscosity.Typically, such paints are from INTERCHEMICAL COHPORATION of New York Cifcy, New York, USA. Each blanket 127 prints all four colors and applies a coating of varnish, the number of blanket assemblies on a given drum assembly 14 being the relative speeds of rotation of the mandrel assemblies IJ, the mandrel assembly 14 and the number of mandrel assemblies 48 carrying the containers to be printed and is set.

As shown in FIG. 14, the paint-applying ends extend Wipes 131b to 135b on the colored inking rollers 131a, l? 2a, IJ ^ a and 134a as well as the paint application roll 135a only to a part around the scope of each role and are positioned so that the rollers 131a to 135a move laterally gauges are driven with respect to the drums 121; the blanket 135b misses the printing drum parts 128 and applies a lacquer coating only to the lacquer-applying parts 129, while the wipes 131b to 134b the printing drum parts 129 and miss a job Apply to parts 128 only. It should be noted that the ordering arrangements I3I 1 to 135 may be of the type described in U.S. Patents 2,718,847, 3,3308,754, or 3,195,451 and, since they do not form part of the invention, they are intended to

Work catfish

In operation, two rows of containers C are conveyed by the pair of inclined container delivery conveyor assemblies 1 and Io the star wheel mechanisms 11 are supplied. As Figures 1 and 4 indicate in particular, take the slightly upwardly inclined belts 27 the container C and, as they move at a considerably greater speed as those of the belts 25 move, they work so that the leading containers C are separated and counterclockwise b are turned over so that they are actually pivoted upwards into the pockets 34 which are in the Lower star wheel elements 35 are provided - Fig. 1 -. These run continuously counterclockwise in direction d »

From the upper star elements 4o, the containers C are individually to a location between the loader or transfer assembly

12 and the mandrel drum 13 directly opposite the migration orbit the container support mandrels 47. As the various mechanisms are timed and driven continuously there is a slide plate 57 in a position in which a container C is pushed onto the mandrel 47 at the moment becomes where the container C arrives opposite a mandrel 47. This working method makes it necessary, of course, that the mandrel drum 1J5 timed with the other mechanisms is driven, so that a mandrel 47 is at that moment in the position where he one Container C takes up. As shown in FIG. 5, the mandrel moves .47 with a container that hardly fits over its end C continues to move, the pusher element 57 hereby in time and gradually pushes the container C onto the mandrel 47. So the chains 63a and 63b have to be slightly smaller Speed than the mandrels 47 move.

The mechanism 12 is assisted in loading the containers onto the mandrels 47 by suction forces which are applied to the containers C. be placed through mandrel openings lol in each mandrel 47. to At this point in time an opening 2o2 is aligned in the one particular one The rotating disk 19I representing the mandrel is essentially radial with the bearing arrangement 12 and is connected to the vacuum opening in the fixed disk I89 through the vacuum slot 2ol in the Washer I09 in connection. The suction forces thus come to Action and assist the loader plates 57 to pull the containers C the rest of the way on the mandrel 47. The suction forces are maintained (note the length of the slot 2ol), which keeps the containers C securely in place for as long be held until the containers C have been printed and moved away from the printing station.

As previously mentioned, the pusher plates 57 are caused by the nook 79 to compress the springs 69 and the

Follow the Urafangsbahn of Dorne 47. While a single mandrel 47 is approaching the printing station, the hollow 116 * on the ram arm 112 of the mandrel arm or the lever arrangement 48 grips the stationary Nooke II7 supported against the frame and is thereby pivoted about the pivot pin 88. If the machine is operating normally and the containers C are stored on each of the pairs of mandrels 47 of a particular mandrel arrangement 48, the vacuum condition is maintained in the line Io7. obtained, the diaphragm Io4 comes into a position in which the diaphragm shaft part Ho in FIG. 11 is located, as a result of which the tappet arm 112 can pivot slightly relative to the block 111. In this situation, the pair of mandrels 47 will remain in the "off" position and will not be moved to an off position. However, if, for example, the supply of the containers C to the conveyors Io is inadequate to ensure that each mandrel 47 is also loaded and no container C is on one of the mandrels 47, the line I07 is opened against the pressure of the air in the room by the printing machine operating at a point in time when the vacuum slot 2ol is still in communication with the vacuum line 197. If the vacuum condition in the diaphragm chamber Io5 is released, the rod I09 is pushed to the right in FIGS. 9 and 11, whereby the sleeve Ho is positioned between the block part 112a and the block 111 ″ the pin 88 is pivoted by the block 111 and the arm 89 and the mandrels 47 thereupon are moved in direction 1 to the remote position in which the bare mandrel does not come into contact with a printing drum cloth 127.

As previously indicated, each mandrel 47 leaves more than one and preferably make two revolutions as it passes a towel 127. During the first turn the container is rotated relative to the cloth part 128 and. will

One revolution of the mandrels 4-7 and thus the one held thereupon by the suction forces Container C is replaced by drive strips IJo of the same length which is resilient like the cloth material and can be referred to as friction drive surfaces. The springs 90 are adjustable so that the one desired for printing Pressure is supplied and of course hold the mandrels 47 in the off position. The thorns "swim" in the direction of the springs 9o * which causes them to move the printing drum that acts as a nooke. The drum 14 runs in a timed relationship with respect to the drum Γ5 *, however, faster than this.

The container unloading mechanism 15 is assisted by pressurized air flowing through the mandrel openings lol Delivered via the stationary slots 2oo in the disk 190 connecting to a source of compressed air 198. As mentioned earlier, each of the openings represents 2o2 in the rotating disc 19I is a mandrel assembly and is aligned with the slot 2oo when the containers are printed on the individual mandrel assembly and are opposite the unloading mechanism I5. So moved Compressed air first removes the container C a small distance from the mandrels 47, but the stop elements 1J37 hold the Container C on the single pair of mandrels 47 until they ready to be removed by the suction cups I70. As mentioned earlier, the suction cups go through I70 a way in which they are held in alignment with the circumferential path of the mandrels 47 under the influence of the cam track 174. At the same time, the cam 72 adjusts the position of the suction cups 170 relative to the path of the container ends so that the

BATH ORIGINAL

Suction cups do not tend to slide as they move along with the containers and face to face can be withdrawn from the containers. If the suction cups 17o approach the discharge or pick-up conveyors 16, they hold Cams 175 the suction cups 170 aligned (Squared) with the Running surface of the conveyor 16, so that the containers are deposited in an upright position and do not tip over. Once a Container C is once firmly seated on a discharge conveyor 16, so this particular opening 177b moves for a suction cup beyond vacuum slot 18I in manifold I80 and the vacuum is released on the suction cup I70 so that it actually the container C, which it is to the discharge conveyor 16 has worn, releases.

It should be noted that the drawing and description are only intended as an interpretation for the measure are to be viewed according to the invention and are not intended to limit it in any way; various changes and amendments on the various elements are of course possible to achieve similar results within the scope of the invention.

If the word "print" is used in the documents, then should this generally refer to anything that is transferred through the wipes to the containers so that underneath actually printed words, coatings, but also purely ornamental patterns are to be understood.
