Definitions

  • the invention relates to a tampon printing machine with a holder for a cliché, with an ink supply device having a hollow body, the end face of the hollow body resting at least temporarily on the cliché when the machine is working, with a device for pressing the end face of the hollow body against the cliché, whose contact force acts in the immediate vicinity of the contact surface between the cliché and the hollow body, with a device for generating a relative movement between the cliché and the hollow body, the hollow body being pivotable about an axis which is essentially parallel and about a transverse to the relative movement and with a Tampon that can be pressed onto the inked cliché and picks up the color from the recesses in the cliché and transfers it to an object to be printed.
  • the ink container which is open at the bottom and whose lower edges are sharpened in a wedge shape, performs the squeegee function.
  • the publication does not contain any information about the material of the paint container. If such an ink container is made from conventional material, for example steel, brass or plastic, the number of prints that can be produced is limited because of the wear on the lower edge of the ink container and the resulting insufficient doctor blade effect.
  • a pot which is only open on one side is also provided as an ink container, the edge of which is made of a relatively soft material, namely a plastic.
  • the number of printing processes that can be carried out per hour is limited by the fact that the distances that the moving parts have to cover cannot be covered in any short time, because otherwise the parts would accelerate too much.
  • the speed of movement is increased too much, there is the possibility that an additional squeegee will stand out from the surface of the plate because the more or less liquid or pasty ink on the surface of the plate causes the squeegee to float could, so that the cliché can no longer be scraped off properly.
  • the invention has for its object to provide a machine of the type described, in which the number of prints that can be produced is increased.
  • the hollow body has hard material with a hardness of at least 1000 HRC (Rockwell C) on at least part of the circumference of its end face and is finely machined with a roughness depth of at most 2 ⁇ m, and that the device for pressing the hollow body onto the cliché is designed such that the pressing force is distributed at least approximately uniformly on the circumference of the end face.
  • HRC Rockwell C
  • the contact pressure is distributed at least approximately evenly around the circumference of the hollow body, tilting of the hollow body is prevented, and this also lies close to the cliché when the relative movement occurs. Because the hollow body can be swiveled around two axes, it can rest perfectly on the cliché with its entire face. The end face, which is pressed against the cliché by the pressing device, can always adjust parallel to the surface of the cliché.
  • the hard material can be processed with high precision and does not change its shape over a long period of time, even if printing inks are processed that contain components that exert a grinding effect on prolonged exposure.
  • the hollow body also does not damage the cliché, which is preferably formed by an engraved or etched steel plate. Other materials are also possible for the cliché. Currently plastic (because of the softness) and glass (because of the high friction) are not considered suitable.
  • hard metal or ceramic can be used as the hard material.
  • the final shape of the end face in the area of its contact with the cliché is expediently carried out by lapping these hard materials.
  • the hardness of the hard material given above is comparable to a value of 1000 of a Rockwell hardness C. It can be advantageous Ma material with the greatest hardness, e.g. comparable to a hardness of 1600.
  • the expression “comparable” is used here because the Rockwell hardness C is only defined up to a maximum value of 100.
  • the end face of the hollow body also lies in one plane.
  • the end face can have a shape in section that is similar to the cross section of known doctor blades; In particular, it is advantageous if the end face is seated on the cliché only with a relatively narrow area, because this favors a reliable stripping of the color.
  • the cliché is moving and the hollow body is stationary; this also applies to the exemplary embodiment described later.
  • the end face of the hollow body is designed only on part of its circumference so that it can act as a wiping edge or squeegee, it is sufficient if this part of the end face is on the side of the hollow body on which there is also after inking and doctoring through the mentioned part of the end face is the inked cliché, from which the ink is then removed by the tampon.
  • the part of the end face which acts as a wiping edge ensures that the part of the plate which comes under the area of the tampon is scraped off cleanly.
  • the end face of the hollow body is designed over its entire circumference so that it can act as a wiping edge, whereby the leakage of color, if not completely, can be prevented to such an extent that the cliché may need to be cleaned at intervals of several hours.
  • the hollow body preferably consists of hard material in the region of its entire end face or is coated with it.
  • the stripping off of the paint is also referred to here in the manner of the known machine as doctoring.
  • the contact pressure is preferably adjustable in order to be able to adapt it to the respective requirements.
  • the contact pressure depends on the size of the contact surface between the hollow body and the cliché.
  • the hollow body is supported in a housing receiving it against displacement relative to the housing parallel to the relative movement between the cliché and the hollow body in the vicinity of the contact surface between the cliché and the hollow body by a lateral support.
  • This deep-seated support namely in the vicinity of the contact surface, keeps the torques generated by the relative movement, which tend to lift the end face of the hollow body partially from the cliché, to be small.
  • the lateral support for the hollow body is preferably arranged in a stationary manner on the housing. This feature inevitably means that this support is completely independent of the generation of the pressing force acting on the hollow body. This also supports the secure contact of the end face of the hollow body with the cliché.
  • the hollow body is pivotably guided by a bearing having a curved surface. It can be z. B. is a spherical bearing or, according to another embodiment of the invention, a bearing which has an annular support bearing with a spherical inner surface against which a counter surface of the hollow body is supported.
  • the term “ring-shaped” is intended to include both a circular arrangement and an angular arrangement, in particular a quadrangular arrangement.
  • the hollow body can have an outwardly projecting bead in its lower end region, which forms the rounded support surface, which is supported against flat counter surfaces (with a rectangular cross section of the hollow body) or against a circular cylindrical counter surface (with a round cross section of the hollow body).
  • the hollow body can be in one piece in the machine according to the invention.
  • the hollow body is in several pieces and has mutually movable parts which are connected to one another in a liquid-tight manner, and part of the end face is provided on one part of the hollow body and another part of the end face on another part of the hollow body.
  • This embodiment enables dimensional changes of the hollow body in the area of its end face, namely a shortening of the dimensions, without the help of the manufacturer of the hard metal part or hard metal coating.
  • This embodiment also simplifies the manufacture of the hollow body overall.
  • Said liquid-tight connection between the parts of the hollow body can be formed by a liquid-tight contact of the parts without these parts having to be firmly or even non-detachably connected to one another.
  • the hollow body can be formed from more than two parts, but it is generally simpler to produce from no more than two parts.
  • the hollow body is divided into two parts, each of which is a wall, two at right angles to this arranged side walls and a substantially perpendicular to the wall and the side walls of the top wall, the side walls of the two parts abutting one another with surfaces substantially perpendicular to the plane of the cliché.
  • the abutting surfaces of the parts which are movable relative to one another are extremely precisely flat, in particular flat, and lapped so that they adjoin one another in a liquid-tight manner and prevent paint from escaping from the hollow body.
  • the two parts are preferably resiliently pressed against one another.
  • one of the two parts of the hollow body can be formed by an essentially flat plate.
  • the clamping device is designed such that the individual parts of the hollow body are pressed against the cliché, and in one embodiment, each of the parts of the hollow body is assigned its own clamping device. This favors a secure contact of the individual parts of the end face with the cliché.
  • the hollow body or its individual parts in the region of the end face are so massive that they can be regarded as absolutely rigid.
  • the end face can be slightly rounded in embodiments of the invention. This is particularly advantageous if one of the parts of the hollow body can sit on the cliché with different inclinations.
  • the end faces running parallel to the direction of displacement have no squeegee function, but only the function of sealing aprons which are intended to prevent the escape of paint. It appears possible to replace these sealing aprons with elastic parts made of metal or plastic without loss of quality. It should also be borne in mind that the cliché in the area of these sealing aprons has no etching, but is completely smooth.
  • the hollow body is mounted in a transport device which moves it relative to the cliché.
  • the hollow body is arranged essentially immovably in the machine and a drive device moving the cliché is provided.
  • This last-mentioned embodiment can be developed in such a way that the cliché, more precisely that part of the cliché which contains the inked and scraped-off engraving, is located in the path of the tampon which it describes when the object to be printed is printed.
  • the tampon only partially carries out the above-mentioned path, and after the ink has been removed and when the tampon is no longer in contact with the cliché, the cliché is moved under the hollow body to recolor, and the tampon can now print on the object mentioned.
  • This embodiment in particular is suitable for printing objects within a production line or transport line in a place that is difficult to reach.
  • the cliché and the hollow body of the tampon printing machine can be located above the production line, for example, and the tampon is connected to a sufficiently long push rod, which allows the tampon to be moved down a possibly considerable distance after the ink has been removed from the cliché, to print on the object in a place where the entire pad printing machine would have no space.
  • the print to be applied is relatively small in area, i.e. only a few millimeters or a few centimeters in size
  • the tampon can also be relatively small and light and can therefore be moved quickly even with a simple design effort, so that a large number of printing processes are carried out per unit of time can be.
  • the cliché can be moved away from the hollow body by lateral displacement so that the ink can flow downwards by means of a suitable arrangement. Removal of the paint from the hollow body without the risk of contamination is promoted by a further device described below.
  • a filling of the hollow body with relatively small dimensions of the machine is sufficient for several hours of working time of the machine or even for an entire shift (about 8 hours), it is not absolutely necessary to take care that during the barrel of the machine can be filled with paint in the hollow body. However, if necessary, this can be done continuously or in batches through an opening in the top of the hollow body without difficulty.
  • the plate holder that holds the plate is at least twice as long as the length of the impression to be produced in the direction of the relative movement between the plate and the hollow body.
  • this enables the ink to be conveniently removed by the tampon, on the other hand, it also makes it possible to further develop the machine according to one embodiment of the invention in such a way that the plate holder is designed to hold a number of plates, such that a of the plates can be replaced while another of the plates completely closes off the hollow body, and that at least one of the plates is a cliché, i.e.
  • the plates which are not designed as a cliché, are finely machined on the side facing the hollow body in the manner of a cliché.
  • the tops of the two plates abut each other without a step, ie they are at least in the same plane in their contact area.
  • two plates are provided in this embodiment of the invention, namely a plate and a plate that is identical to the plate in terms of surface quality but is not engraved.
  • the non-engraved plate closes the hollow body during those times when the cliché is in the position in which the ink can be removed from the cliché by the tampon. In this position of the cliché, the cliché can also be exchanged for another cliché when the machine is at a standstill.
  • a further cliché can also be provided, in particular if the machine is designed in such a way that the color can be removed from both clichés using one or more tampons.
  • An engraved cliché is just as suitable for closing the hollow body when a cliché is being exchanged as a non-engraved plate.
  • one of the plates provided for insertion into the plate carrier is designed such that its surface facing the hollow body is sealed off with its end face, and that the plate has a recess through which the color contained in the hollow body can be derived.
  • a container can preferably be arranged on the plate, in which the paint flowing out of the hollow body is collected, so that any risk of contamination of the machine is prevented.
  • the hollow body can have such a large cross section that it completely covers the engraving of the cliché.
  • a cross section of the hollow body adapted to this maximum possible engraving in the region of its open end face must then be provided for a machine for a cliché of a predetermined maximum width, which is limited by the width of the cliché carrier, and a predetermined maximum length, which is limited by the possible displacement movement.
  • the dimensions of the hollow body transverse to the relative movement between the cliché and the hollow body smaller than the width of the engraved area if it is provided according to one embodiment of the invention that transverse to the direction of the relative movement between the cliché and the hollow body via the Width of the plate several hollow bodies are arranged distributed.
  • This embodiment can be useful because a plurality of relatively small hollow bodies can be produced more easily and cheaply than a single large hollow body, and because these small hollow bodies in the corresponding number for a plurality of machines, which are characterized by a different permissible width of the Differentiate clichés that can be used.
  • the machine 1 which is a tampon printing machine for fast printing of flat surfaces and preferably of bodies with an uneven surface by means of a tampon 2 made of silicone rubber, has a base body or a machine frame 4 on which the other parts of the machine are arranged.
  • the tampon 2 is fastened to a guide column 8 which is mounted in the guide piece 6 and can be displaced in the vertical direction on a guide piece 6 projecting forwardly beyond the rest of the frame 4.
  • the guide column 8 is connected to the tampon 2 via a holding plate 10 to which the lower end of a piston rod 12 of a pneumatic piston-cylinder unit 14 is attached.
  • On the holding plate 10 is also a parallel to the longitudinal direction of the piston-cylinder unit 14 and the guide column 8 arranged shift rod, which carries height-adjustable switching cams 17 and 18, which cooperate with invisible limit switches and serve to adjust the stroke length of the tampon 2.
  • two mounting plates 19 and 20 are screwed parallel to one another at a distance, the lower end region of which each has a plurality of upper guide rollers 21, all of which are arranged at the same height in one plane, and a plurality of lower guide rollers 22, which are just in one said plane are arranged parallel plane, which upper and lower guide rollers 21 and 22 are arranged on the mutually facing surfaces of the mounting plates 19 and 20.
  • a cliché holder 24 is slidably guided between the upper and lower guide rollers 21 and 22, the cliché holder 24 being supported with its upper side 25 and its lower side 26 on the upper and lower guide rollers 21 and 22 and being guided by these in an exactly linear manner.
  • the leadership through the leadership roles is practically without a game.
  • the plate holder 24 has contact shoulders 28 on which a plate 30 is supported from below, which is held in this position by clamping strips 32 which are screwed onto the underside of the plate holder 24 and act on the underside of the plate 30.
  • the clamping strips 32 leave space for the lower guide rollers 22.
  • the cliché 30 consists of a steel plate and has a completely flat upper surface 35, which is finely machined by lapping, into which an engraving, not shown, is introduced, which can either be actually produced by engraving or also by etching, in particular in a photochemical process.
  • a plate 40 is clamped in the cliché holder 24, the top 42 of which is completely flat and in exactly the same way as for the cliché 30 is finely finished by lapping. This top 42 is not engraved.
  • the plate 40 is pressed against the contact shoulder 28 of the plate holder 24 by releasable and attachable terminal strips, independently of the terminal strips 32, which are visible in FIG.
  • the cliché 30 and the plate 40 can thus be fastened and detached from the cliché holder 24 independently of one another.
  • the upper sides 35 of the clichés 30 and 42 of the plate 40 abut one another without joints and lie exactly in the same plane. To ensure this, the contact shoulder 28 of the plate holder 24 is machined with sufficient accuracy.
  • the plate holder 24 with the parts attached to it can be displaced by a pneumatic piston-cylinder unit 46 which is fixed in the frame 4 and whose piston rod 47 is connected via a connecting piece 48 to a connecting piece 49 which adjoins the plate holder 24 at the rear.
  • the kiischeeha! Ter24 is displaceable in the direction of the double arrow 50 by the piston-cylinder unit 46.
  • a through bore 52 running in the vertical direction, which is somewhat enlarged in its upper end region 54.
  • a ring 58 is suitably inserted and fixed in a recess 56, the radially inwardly facing surface 60 of which is spherical in longitudinal section, cf.
  • FIG. 2 in particular is inserted into the bore 52, which has a circular cylindrical side wall 66 to which an end wall 68 adjoins at the top and is provided with a central threaded bore 70.
  • a tube 72 is screwed into the threaded bore 70 from above and protrudes beyond the top side 74 of the frame 4.
  • the tube 72 is closed airtight on its upper side by a releasable screw plug 76.
  • the side wall 66 of the hollow body 64 has a collar 80 which projects radially outwards with respect to its remaining outer surface 78 and whose outer surface 82 forms a circular cylindrical surface.
  • the upper side 83 of the collar 80 forms an abutment shoulder on which a spring 84 designed as a compression spring, namely as a helical compression spring, is supported with its lower end.
  • the upper end of the spring 84 is supported on a shoulder 86, which is provided on a quick-release fastener 88 inserted into the enlarged area 54, which has a knurled wheel 90 at its upper end for easier handling and in the frame 4 with the aid of projections 92 Kind of a bayonet lock is held.
  • the quick release 88 is drilled lengthways, and the diameter of this bore 94 is larger than the outer diameter of the tube 72, so that the quick release 88 possible lateral movements of the Tube 72 and therefore corresponding movements of the hollow body 64 are not hindered.
  • the spring 84 is designed such that it transmits the desired contact pressure to the collar 80 without any further adjustment possibility. If an adjustment of the contact pressure is to be provided, this is possible without difficulty by providing a screw which essentially corresponds to its dimensions instead of the quick-release fastener 88, the area 54 of the bore 52 then being designed as a threaded bore. The contact pressure of the spring 84 can then be adjusted by screwing in this screw, which replaces the quick-release fastener 88, accordingly.
  • the wall thickness of the hollow body 64 decreases.
  • the narrow annular end face 96 (cf. FIG. 2a) of the hollow body 64, which is in contact with the cliché 30, is like the upper side of the cliché 30 and the like Plate 42 very precisely flat and lapped.
  • the hollow body 94 is made of a hard material in the immediate vicinity of the end face 96.
  • the lower end region of the hollow body 64 is formed by a ring 98 having the end face 96 made of hard material, in the example made of hard metal, whereas the remaining hollow body 64 consists of steel.
  • the ring 98 is produced by sintering and is connected to the remaining hollow body 64 by brazing.
  • the hollow body 64 could also be made in its lowermost region from steel, onto which hard metal or hard metal oxides have been applied by means of a suitable coating method, in particular the plasma spraying method, with the required smoothness subsequently also here the end face 96 is produced by fine grinding and lapping.
  • the printing ink 110 contains a relatively high proportion of volatile solvents.
  • the distance between the upper side 83 of the collar 80 and the lower end face 96 is approximately half the diameter of the hollow body 66 in the region of its lower end face 96.
  • the cliché holder 24 is moved forwards by the piston-cylinder unit 46, that is to say to the left in FIG. 1, until the plate 40 has exactly assumed the position that the cliché 30 in FIG. 1 occupies. During this shifting process, the end face 96 of the hard metal ring 98 strips off excess paint from the top of the plate 30, so that only color remains in the depressions of the top of the plate. This colored area of the cliché is now located below the tampon 2. Now compressed air is supplied to the piston-cylinder unit 14, which moves the tampon 2 downwards and presses it onto the cliché. The tampon 2 is then lifted off the cliché again and takes the printing ink from the recessed areas of the cliché. Now the cliché holder 24 is again moved into the position shown in FIG.
  • the tampon 2 consists of a silicone rubber and is elastically deformable.
  • the contact pressure with which the tampon 2 is pressed against the top of the cliché 30 is expediently such that the tampon deforms only to such an extent and only lies flat against the cliché in such a large area as for receiving the in the engraved area of the cliché color is required.
  • the engraved area of the cliché expediently has an all-round distance from the inner boundary of the end face 96 when the cliché 30 is shown in FIG. 1. This ensures that small traces of paint, which can accumulate on the edge of the area of the plate 30 and the plate 40 which is covered by the end face 96 when the plate holder 24 is moved, are not picked up by the tampon 2.
  • the cliché is completely clean in the area lying within this edge area.
  • the hollow body 64 is held in its position by the ring 58, the spherical inner surface of which allows a slight pivoting movement of the collar 80 about axes running parallel to the top of the plate, and by the compression spring 84. Since the compression spring 84 is located in an area just above the top of the plate on the collar 80 attacks, there is a favorable lever arm, which strives to prevent any tilting of the hollow body 64 due to frictional forces that occur during the displacement movement of the plate carrier 24. However, it should be noted that the printing ink used has a certain lubricating and therefore friction-reducing effect.
  • the end face 96 is always close to the top of the plate 30 or the top of the plate 40. This creates an all-round seal.
  • the pressure with which the lower end face 96 rests on the upper side of the cliché 30 and the plate 40 is also approximately the same in the entire circumferential area of the end face 96. This prevents uneven wear, especially on the top of the plate. The lifespan of the clichés is therefore very long. The end face 96 practically does not wear out.
  • the printing ink 110 does not have to be removed from the machine when the machine is at a standstill, even if it has been idle for the weekend. As soon as the work starts again, the machine can start printing without time-consuming cleaning work.
  • the cliché 30 If the cliché 30 is to be replaced, it is only necessary to move the cliché support 24 from the position shown in FIG. 1 to the position indicated by dash-dotted lines without the tampon 2 being lowered onto the cliché 2. The cliché 30 is then replaced. During this time, ink 110 is prevented from escaping from inside the hollow body 66 through the plate 40.
  • FIG. 2b differs from the embodiment shown in FIGS. 1 to 2a in that the hollow body designated here with the reference numeral 64a has a support surface 83a for the spring 84 which is lower than in FIG. 2. Also the spherical surface 60 'corresponding to the surface 60 offers a support for the hollow body 64a which is lower than in FIG. 2. In the exemplary embodiment, this support formed by the surface 60a is 6.5 mm above the top of the cliché, and the surface 83a is 8 mm above the top of the cliché.
  • the auxiliary device 120 used in FIG. 4 is used.
  • the auxiliary device 120 is shown in a section perpendicular to the drawing plane of FIG. 1. It has a plate 125 in its upper area, the dimensions of which correspond entirely to the dimensions of the plate 30 and the plate 40. The plate 125 is particularly finely machined on its upper side.
  • the cliché 30 is exchanged for the auxiliary device 120 in the manner described above.
  • the plate carrier 24 is again moved into the position shown in FIG. 1 and a bore 128 arranged in and penetrating the plate 125 is now connected to the interior of the hollow body 64.
  • the locking screw 76 is now loosened, and because air can now flow into the hollow body 64, the printing ink 110 flows into a container 130 provided below the plate 125 on the auxiliary device 120.
  • the top of the plate 125 like that of the plate 40, is microfinished and then, when the auxiliary device 120 is mounted, smoothly merges into the top of the plate 40.
  • the container 130 can also be chosen larger than that provided in the exemplary embodiment.
  • FIG. 5 shows a hollow body 164 which differs from the exemplary embodiment in FIG. 1. This is completely closed in the region of its upper end wall 168, and a rod 173 made of solid material is therefore screwed into the end wall 168 instead of the tube 72.
  • This rod 173, like the tube 172, is also used, inter alia, for inserting the hollow body and for removing the hollow body for any maintenance tasks.
  • the entire machine is expediently pivotably arranged such that it can be rotated such that the end face 96 of the hollow body 164 points upwards.
  • the hollow body 164 is then removed downward from the machine with the aid of the rod 173 (after the quick-release fastener 88 has been released) when printing ink is to be filled into the hollow body or removed therefrom.
  • the printing ink is thus filled into the hollow body 164 while the hollow body 164 is located outside the machine; the hollow body is then reinserted into the machine from below.
  • the removal of printing ink present in the hollow body 164 during a color change takes place in the same way, but in reverse order: after the machine has been rotated so that the end face 96 faces upward, the hollow body 164 is removed downward from the machine , so that there is no danger that the machine will be dirty. The hollow body is then poured out, cleaned and provided with a new color and pushed back into the machine.
  • the cross section of the hollow bodies 64 and 164 is, as shown in FIG. 6, circular cylindrical.
  • FIG. 7 A construction different from FIG. 5 is shown in FIG. 7.
  • the contact pressure of the spring 84 can be adjusted in the manner just described by means of a screw 188 replacing the closure piece 88.
  • the upper end of the spring 84 is supported on the screw 188 via an axial ball bearing 190, so that it can be easily adjusted.
  • a rod 173 is not provided here.
  • the hollow body 264 is only open in the area of its end face 96.
  • the drive for the tampon 2 does not necessarily have to have a stroke limitation by means of adjusting rings 17 and 18. It is also possible to supply the piston-cylinder unit 14 with a pressure medium, in particular compressed air, which generates a constant pressure within the piston-cylinder unit 14 when the tampon 2 moves downward. The stroke movement of the tampon 2 is then limited by the fact that the tampon 2 comes to rest on the top of the plate 30 on the one hand and on the top of the object to be printed 115 on the other hand and in the desired manner in accordance with the selected pressure and the elastic properties of the silicone rubber and deformed to the desired extent.
  • a pressure medium in particular compressed air
  • a major advantage of the machine shown is that the plate holder 24 has only a very short displacement path between the position in which the plate 30 is inked and the position in which the ink is removed from the plate 30 by the tampon, and among other things because an additional squeegee is not required. Because of this small displacement path and because the end face 96 of the hollow body 64 or 164 always lies tightly against the upper side of the plate carrier 24 even at high displacement speeds, the printing press can achieve a very high printing speed. In a realized embodiment, in which the cliché holder 24 and the tampon 2 are not yet driven at the highest possible speed, 7000 printing processes per hour were achieved. It is believed that 10,000 printing processes per hour or more can be achieved without difficulty. In contrast, only around 2500 printing processes per hour have hitherto been possible in known machines.
  • the hollow body 64 and 164 has an inner diameter of 25 mm and a clear height of 90 mm.
  • the width of the lower end face 96 is expediently 0.1 to 0.5 mm, in the example 0.3 mm.
  • the ring 98 consists of a so-called hard metal, namely a sintered material produced using metallic hard materials, as is known for. B. also used for cutting tools.
  • the displacement of the plate holder 24 is 50 mm. The remaining dimensions can be found in the scale drawing.
  • the machine 200 shown in FIGS. 8 to 11 differs from the machine according to FIGS. 1 to 7 in the region of the hollow body designated here with the reference number 202.
  • the hollow body 202 is essentially formed from two parts 204 and 210 which are connected to one another in such a way that they can move relative to one another.
  • the part 204 is U-shaped in the horizontal cross section. It has a vertical, flat wall 206, to which side walls 207 and 208 adjoin, which form the legs of the U and run essentially at right angles to wall 206.
  • the vertical end faces of the side walls 207 and 208 are very precisely flat and lapped.
  • the part 210 also has an upper wall 209 running at right angles to the wall 206 and to the side walls 207 and 208. At its lower end region, the walls 206, 207 and 208 taper and here carry a hard metal strip 205 which tapers further downward, the lower end face and the end face of the ring 98 of FIG. 2a forming a wiping edge.
  • the scraper edge formed by the hard metal strip 205 on each wall 206, 207 and 208 runs straight.
  • the part 210 is essentially a mirror image of the part 204.
  • the wall 212 running parallel to the wall 206 thus forms a U in the horizontal cross section with side walls, which are provided here with the reference numerals 213 and 214, and an upper wall 215 connects in the upper region. While the upper wall 209 is closed, a threaded hole 216 is made in the upper wall 215, which allows a sealing plug to be screwed in here or a hose for the continuous or batchwise ink supply to be attached.
  • the vertical end faces of the side walls 207, 208 and 213, 214 and the upper walls 209 and 215 abut one another, the two parts being pressed against one another in a resilient manner. Since the end faces in contact with one another are highly precise, the joint between the two parts 204 and 210 is color-tight.
  • the cohesion of the two parts is ensured by a total of four screws 220 to 223.
  • the screws 220 and 221 are arranged in the lower part of the hollow body 202 so that they pass through the side walls 207, 208, 213, 214, while the screws 222 and 223 in the upper part of the hollow body 202 through the upper walls 209, 215 run at a distance from the side walls.
  • the screws 220 to 223 each have a head 224 which presses a coil spring 225 against a shoulder 226 of the part 204, whereas the threaded part 228 of the screws engages in a matching internal thread in the part 210.
  • grub screws230 which serve as counter screws and also prevent that the screws 220 to 223 can be screwed in too far, the rotational position of the screws mentioned is secured. Since the heads 224 in no case lie against the part 204, a highly uneven clamping of the two parts 204 and 210, which could lead to damage but also to a leakage, is prevented.
  • the screws 220 to 223 including their threaded parts 228 are seated in the part 204 with some lateral play, so that the parts 204 and 210 can shift somewhat along their contact surface relative to one another. This ensures that the hard metal strip 205 of the two parts 204 can fit exactly on the surface of the flat cliché 30, regardless of manufacturing tolerances.
  • each of the parts 204 and 210 of the hollow body 202 there are four bores, which extend parallel to the drawing plane of FIG. 8 and at right angles to the drawing plane of FIG. 9 and are open at the top in FIG. 8, of which the bores 232 in the walls 206 and 212, but are provided in the vicinity of the corners of the rectangular hollow body 202, whereas the bores 234 in the side walls 207 and 208 are provided in the immediate vicinity of the contact surface between the two parts 204 and 210.
  • the lower end of the holes 232 is as deep as possible, it is located just above the hard metal strip 205. Since the longitudinal direction of the holes 234 intersects the screws 224 passing through the side walls, the holes 234 are not quite as deep as the holes 232, 10 shows.
  • Rods 238 are inserted into the bores 232 and 234 from above, and their lower ends press against the bottoms of the bores 232 and 234.
  • the rods 238 do not touch the side walls of the bores 232 and 234.
  • the rods 238 are guided with their upper end sections in a bearing part 240, with an enlarged head 242 of the rods 238 ensuring that the rods are released from the bearing part 240 when it is after removed at the top, cannot fall down.
  • the counterpart 244 is held in place against the force of the springs 248 and in contact with the top of the bearing part 240, it is locked by a latch 252 pivotally mounted in the housing 250, which is held in its locked position by a spring-loaded pawl 254. If the pawl 254 is pivoted back, the latch 252 can be pivoted upwards and the parts 240 and 244 together with the bars 238 can then be removed upwards. The hollow body 202 can then be removed upwards. The exact position of the bearing piece 240 is ensured by the fact that this piece engages with a narrower section in a recess 260 with a rectangular cross-section which passes through the housing 250 from top to bottom. A continuous recess 261 in the parts 240 and 244 allows a hose to be guided to the threaded bore 216 from above.
  • the hollow body 202 With the exception of the slightly beveled corners, the hollow body 202 likewise has a rectangular cross section, but with the exception of its lowermost area it is somewhat smaller than the cross section of the recess 260. Only in the lowermost area of the hollow body 202 does it have a circumferential, outward-facing configuration projecting, convex bulge 262, which fits snugly against the wall of the recess 260. In the lowest area of the recess 260, the latter is lined with hardened steel strips 264 inserted into the housing 250, so that this creates a practically non-wearing support surface for the bead 262.
  • the hollow body 202 above the bead 262 has a smaller cross section than the cutout 260, it can pivot somewhat in the cutout 260 about two horizontal pivot axes which run perpendicular to the plane of the drawing and in the horizontal direction in FIG. 8, and this makes it possible that the scraper edge formed by the hard metal strips 205 is always in exact contact with the surface of the cliché.
  • the visible height of the hollow body in FIG. 8, measured outside, is 60 mm.
  • the maximum width visible in FIG. 8 in the region of the bead 262 is 40 mm.
  • the length of the hollow body transversely to the direction of displacement of the plate, also measured in the region of the bead, is 69 mm.
  • the support formed by the bead 262 is 6.5 mm above the top surface 270 of the plate.
  • the point of attack of the rod 238 within the bore 232 is almost at the same height, namely approximately 7.5 to 8 mm above the top 270 of the cliché.
  • the point of engagement of the rod 238 is approximately 13 mm above the upper side 270. The remaining dimensions can be found in the scale drawing.
  • the machine 200 differs from the machine 1 in that another cliché is used. Instead of the plate 30 and the plate 40, a plate 30a is used, the length of which corresponds to the sum of the lengths of the plate 30 and the plate 40. As a result, it is not necessary to ensure an absolutely smooth transition between the surfaces of the plate 30 and the plate 40.
  • the hard metal parts 205 always slide on the absolutely flat and stepless surface of the cliché 30a.
  • the cliché 30a is exchanged, it is first shifted to the left until it assumes the position shown in dotted lines in FIG. 1, then a fastening screw 290 is loosened, which connects the cliché holder to the connecting piece 48, and it is now the entire plate carrier further forward, so in Fig. 8 shifted to the left.
  • a plate adjoining the cliché 30a then arrives 292, the top of which is machined with high precision, under the hollow body 202 and seals it, while the cliché 30a is replaced.
  • FIG. 12 schematically shows, in a horizontal cross section, the position of three hollow bodies 280 with a round cross section, which are staggered with respect to the displacement direction of the cliché indicated by a double arrow 282 both in this displacement direction and transversely thereto in a housing of a further exemplary embodiment.
  • the machines shown are particularly suitable as built-in printing units in production lines, packaging lines, filling systems and assembly lines with high cycle speeds. They are suitable for printing on completely flat objects as well as for printing on unevenly shaped objects.
  • the maintenance work to be carried out on the printing presses requires little time, and is practically limited to refilling the color from time to time, for example at the end of a shift, or, if necessary, changing a cliché. These activities can be carried out by trained personnel.
  • the machines according to the invention are particularly advantageous because in the case of automatic production lines, many uneven parts have to be labeled and dated, coding or other imprints being required here. These tasks can be taken over by the machines according to the invention without difficulty and allow this pressure to be applied even where this was previously not possible due to the absence of a suitable machine. From a steel cliché, 100,000 to 300,000 prints or more can be produced on the machine.
  • the carbide is a material that is usually used for cutting cutting tools.
  • Such hard metal contains hard materials, e.g. Tungsten carbide.
  • the good sliding properties of the carbide on the steel are also important for the selection of steel.
  • ceramic is used as the hard metal, it can contain silicon carbide or aluminum oxide.
  • the finely machined surfaces are preferably lapped. In this case, a roughness depth of 0.4 11 m can be achieved. In contrast, the diameter of color pigments is generally 3 to 4 1 1m.
  • the total force with which the eight springs press the hollow body 202 against the cliché in the exemplary embodiment according to FIG. Is 20 daN (dean Newton).
  • the hollow body (64, 164, 264, 202) is arranged essentially immovably in the machine and a drive device (46) moving the cliché (30, 30a) is provided, and that the Cliché (30, 30a) in the inked and doctored state in the path of the tampon (2), which this describes when printing on the object to be printed; or that a plate holder (24) is provided which, in the direction of the relative movement between the plate (30, 30a) and the hollow body (64, 164, 264), is at least twice as long as the length of the print to be made that the plate holder (24 ) is designed to hold a number of plates in such a way that one of the plates (cliché (30, 30a) can be replaced, while another of the plates (40) completely closes off the hollow body such that at least one of the plates is a cliché (30, 30a), and that the non-cliché plate or the non-cliché plates
  • a plate (125) provided for insertion into the cliché holder is designed such that its surface facing the hollow body is sealed off with its end face and that the plate (125) has a recess (128) through which the hollow body passes (64) contained printing ink (110) can be derived.
  • a plurality of hollow bodies are advantageously arranged distributed across the width of the cliché across the direction of the relative movement between the cliché and the hollow body, it being possible for at least one of the hollow bodies to be arranged offset with respect to at least one other hollow body in the direction of the relative movement.
