Definitions
- the invention relates to a method for Ta ponschnel Ibuch with tampons, clichés and workpiece holders for the workpieces to be printed, in which the workpieces are fixed in the workpiece holders and in which the tampons take over alternately print images from the inked clichés and transfer them to the workpieces.
- Pad printing machines are known in which the cliché and the workpiece rest during the transfer of the print image and the transfer of the print image.
- the tampon is usually adjusted in three directions in a linear way.
- the workpiece holder After the print image transfer, the workpiece holder also performs a linear movement, so that a new workpiece holder with workpiece is brought into the printing position.
- the tampons, the clichés and the workpieces are each moved synchronously on an endless path, that at least a section of the path with the tampons parallel to a section of the path with the clichés and at least one further section the web with the tampons is arranged parallel to a section of the web with the workpieces and each is moved in the same direction and that in the same running sections of the webs the tampons are alternately adjusted perpendicularly to the assigned sections and for a given path for printing with a colored cliché and for print image transfer ragu ⁇ g with a workpiece in operative connection.
- the tampons, the clichés and the workpiece holders with the workpieces can be moved on the endless webs at a much higher speed and since the printing is carried out by means of a short lateral adjustment during the running movement of the webs, the printing cycles can be increased considerably, with the print image being taken over by one Cliché can run parallel to a workpiece with a print image transfer and several tampons, clichés and workpiece holders can be arranged on the tracks.
- This enables printing speeds to be achieved which lie far above the printing speed of the known pad printing machines with a stationary cliché and a stationary workpiece.
- the structure of the pad printing machine for carrying out the method is much simpler than that of the known pad printing machines.
- the endless tracks are formed by conveyor belts that over Deflection rollers are guided so that the tampons, the clichés and the workpiece holder with the workpieces are arranged in a uniform division on the conveyor belts and that the conveyor belts are continuously moved at a constant speed, then the drive of the conveyor belts is simplified and the movement sequence is easy to synchronize .
- the optimal utilization of the running time of the conveyor belts over the parallel parallel sections for print image transfer and for print image transfer is achieved according to one embodiment in that the adjustment of the tampons perpendicular to the synchronous sections of the conveyor belts is carried out for a duration during the continuous running of the conveyor belts , which is tuned to the throughput time of the conveyor belts through the synchronous sections.
- the conveyor belts with the tampons, the clichés and the workpiece holders with the workpieces are designed and driven identically, that two tampons, two clichés and two workpiece holders are provided for workpieces which are in one half the length of the Conveyor belt can be arranged given division, and that the one strand of the conveyor belt with the tampons, a parallel section of the conveyor belt with the clichés and the other strand of the conveyor belt with the tampons, a parallel section of the conveyor belt with ' the workpiece holders for workpieces can then be assigned Both strands of the conveyor belt with the tampons are deflected in opposite directions during the passage of the synchronized, facing sections, so that on the conveyor belt with the clichés A tampon takes over a print image, while on the side facing the conveyor belt with the workpiece holders, another tampon simultaneously transfers a print image to a workpiece.
- one embodiment provides that the tampons are adjusted perpendicular to the synchronized sections of the conveyor belts so that the tampons in the print image transfer from the clichés and in the print image transfer to the work pieces perform the required maximum deformation path .
- the adjustment movement of the tampons can be derived in such a way that the tampons are adjusted or guided perpendicularly to the synchronous sections by controlled deflection or guidance of the assigned strand of the conveyor belt.
- Controlled deflection or guidance of the conveyor belt strands can be achieved in a simple manner by providing a switch with control cams to adjust the strand of the conveyor belt with which the tampons are supported with control approaches.
- the control curves of the switch are assigned to the two strands of the conveyor belt with the tampons.
- the adjustment of the tampons for transferring the image from the printing blocks and for transferring the print image to the workpieces can, according to one embodiment, also be effected in that the adjustment of the tampons is carried out perpendicular to the assigned synchronous sections of the conveyor belts by appropriate adjustment of the entire conveyor belt with the tampons.
- a continuous inking of the clichés is obtained according to one embodiment in that a coloring device is assigned to the strand of the conveyor belt which is turned away with the tampons and the clichés are inked, which colors the continuous or passing clichés.
- the loading of the workpiece holder with workpieces to be printed and the removal of printed workpieces from the workpiece holders are facilitated in that the number of tampons is chosen equal to the number of clichés, that the number of workpiece holders for workpieces is chosen to be greater than the number of tampons or clichés and that all three conveyor belts are driven at the same running speed.
- the conveyor belt with the workpiece holders can then be arranged so that it projects at both ends of the conveyor belt with the tampons, which facilitates access to the workpiece holders in the projecting sections.
- FIG. 1 is a schematic representation of a pad printing machine for performing the method according to the invention
- Fig. 2 shows schematically a modified pad printing machine for performing the method according to the invention
- Fig. 3 shows another variant of a pad printing machine for performing the method according to the invention.
- three endless tracks 10, 20 and 30 are formed by three endless conveyor belts.
- the middle conveyor belt forming the web 10 carries the tampons 13 and 14 and is guided around the deflection rollers 11 and 12.
- the tampons 13 and 14 are attached in a Tei treatment that corresponds to half the length of the conveyor belt.
- the upper run of the conveyor belt with the tampons 13 and 14 is associated with the conveyor belt forming the web 20 with the clichés 23 and 24.
- This conveyor belt is guided over the deflection rollers 21 and 22 and carries the clichés 23 and 24 in the same division, since both conveyor belts are constructed and designed identically.
- the direction of rotation is selected so that the upper run of the conveyor belt with the tampons 13 and 14 at a distance parallel to the lower run of the conveyor belt with the clichés 23rd and 24 is arranged, and that both strands of the two conveyor belts are moved in the same direction in this section. This means that the conveyor belt with the clichés
- the inking device 25 is assigned to the upper run of the conveyor belt with the clichés 23 and 24.
- the lower run of the conveyor belt with the tampons 13 and 14 is associated with the conveyor belt forming the endless path 30 with the workpiece holders receiving the workpieces 33 and 34.
- the upper run with the .workpiece 33 is moved in the same direction as the lower run of the conveyor belt with the tampons 13 and 14.
- the conveyor belt with the workpiece holders is guided over the deflection rollers 31 and 32 and constructed identically to the conveyor belt with the tampons 13 and 14, as well as the conveyor belt with the clichés 23 and 24.
- all three conveyor belts can be driven most simply by a common drive device which, for example, in the same way can be coupled to the pulleys 11, 21 and 31.
- the distances between the synchronous sections of the conveyor belts with the clichés 23 and 24 and the tampons 13 and 14, as well as the sections of the conveyor belts with the tampons 13 and 14 and the workpiece holders are the same size and matched to the dimensions of the tampons 13 and 14.
- the clichés 23 and 24 are colored. If the upper run of the conveyor belt with the tampons 13 and 14 on the deflection roller 11 is adjusted upwards, which can be achieved by a controlled deflection or a fixed guidance of the conveyor belt itself, then the tampon 13 comes with the cliché 23 in operative connection. This active connection is maintained until the tampon 13 is moved downwards and is lifted off the cliché 23. The printed image is taken from the inked cliché 23 by the tampon 13. The tampon 13 must be adjusted so far up that it can perform its maximum deformation. The adjustment can be selected according to the size of the printed image and limited accordingly.
- the tampon 14 is adjusted downward and brought into operative connection with the workpiece 33.
- the adjustment path is set and limited to the required deformation path of the tampon 14.
- the tampon 14 is adjusted upwards again and lifted off the workpiece 33.
- the printed image has been transferred from the inked tampon 14 to the workpiece 33.
- the conveyor belts can be put into circulation at high speed.
- the adjustment paths of the tampons 13 and 14, which run perpendicular to the conveyor belt runs, are short, with sufficient time remaining for the necessary deformation of the tampons 13 and 14.
- both tampons are 13 and 14 accept print images from clichés 23 and 24 and transfer them to workpieces 33 and 34.
- the alignment of the conveyor belts must be such that in one position the clichés 23 and 24, the tampons 13 and 14 and the workpieces 33 and 34 or their workpiece holders lie on the central axis of all three conveyor belts which is perpendicular to the conveyor strands.
- the length of the conveying strands, which form the synchronous sections of the endless webs 10, 20 and 30, and the rotational speed are the parameters which determine the printing speed.
- the adjustment path of the tampons 13 and 14, which is directed perpendicular to the conveying doors, must be carried out in the directions indicated and initiated and ended when these sections pass through.
- the middle conveyor belt carries only the tampon 13 and the upper conveyor belt only the cliché 23.
- the division is thus determined by the length of these two dental conveyor belts.
- the lower conveyor belt has workpiece holders for two workpieces 33 and 34, which are arranged in the same division on the conveyor belt which is twice as long.
- the arrows indicate the running directions of the conveyor belts of the conveyor belts.
- the conveyor belt passes with the tampon 13 back to its middle position, wherein the tampon 13 lifts from the cliché 23rd If the inked tampon 13 runs into the lower run of the conveyor belt, then the entire conveyor belt becomes mt the tampon 13 adjusted downwards.
- the workpiece 33 has in the meantime been moved on the endless path 30 so that it comes into operative connection with the lowered tampon 13 in the upper run.
- the printed image is transferred from the inked tampon 13 to the workpiece 33.
- FIG. 3 shows an exemplary embodiment in which the web 10 is covered with six tampons 13 and the web 20 with six clichés 23.
- the track 10 with the tampons 13 is assigned a switch 15 which has the two control cams 16 and 17.
- the tampons 13 have control lugs 18 which move through the synchronous sections, i.e. support the two strands of the web 10 on the control cams 16 and 17 and control the adjustment of the tampons 13 for transferring the print image from the printing blocks 23 and for transferring the print image to the workpieces 33.
- the conveyor belt 30 bi ldd has a number of workpiece holders, which is greater than the number of tampons 13 and the number of clichés 23.
- the rotational speeds of all conveyor belts are the same, so that with uniform division of tampons 13, clichés 23 and workpieces 33 ensures that when the tampons 13 are adjusted via the control cams 16 and 17, the Wi rkverbi ⁇ dungen continuously produced by the tampons 13 to the clichés 23 and to the workpieces 33 and be canceled again.
- the number of workpieces 33 is preferably an integral multiple of the number of tampons 13 or the number of clichés 23. In this way, a corresponding number of revolutions of webs 10 and 20 that fall through this fall on one revolution of web 30 integer multiples is given.
- the ends of the web 30 protrude at both ends of the web 10 with a section. In these sections, access to the workpiece holders is facilitated, which on the one hand favors the introduction of the workpieces to be printed into the workpiece holders and, on the other hand, the removal of the printed workpieces from the workpiece holders.
Abstract
Selon le procédé d'impression rapide avec des tampons (13, 14), des clichés (23, 24) et des supports pour les pièces à imprimer (33, 34), les pièces (33, 34) sont fixées dans les supports; les tampons (13, 14) prennent les images des clichés encrés (23, 24) etles reportent sur les pièces (33, 34). La vitesse d'impression peut être notablement augmentée par une synchronisation des déplacement des tampons (13, 14), des clichés (23, 24) et des pièces (33, 34) le long de trajectoires fermées (10, 20, 30). Une partie au moins de la trajectoire (10) des tampons (13, 14) est parallèle à une partie de la trajectoire (20) des clichés (23, 24). Au moins une autre partie de la trajectoire (10) des tampons (13, 14) est parallèle à une partie de la trajectoire (30) des pièces (33, 34). Le déplacement des parties correspondantes se fait dans le même sens. Dans ces parties correspondantes des trajectoires (10, 20, 30), sur un tronçon déterminé, les tampons (13, 14) sont tour à tour déplacés perpendiculairement pour la prise de l'image sur un cliché encré (23, 24) et pour la transmission de celle-ci sur une pièce (33, 34).According to the rapid printing method with pads (13, 14), clichés (23, 24) and supports for the parts to be printed (33, 34), the parts (33, 34) are fixed in the supports; the buffers (13, 14) take the images of the inked plates (23, 24) and transfer them to the parts (33, 34). Printing speed can be significantly increased by synchronizing the movement of pads (13, 14), plates (23, 24) and parts (33, 34) along closed paths (10, 20, 30). At least part of the trajectory (10) of the buffers (13, 14) is parallel to a part of the trajectory (20) of the negatives (23, 24). At least another part of the trajectory (10) of the buffers (13, 14) is parallel to a part of the trajectory (30) of the parts (33, 34). The movement of the corresponding parts is done in the same direction. In these corresponding parts of the trajectories (10, 20, 30), on a determined section, the buffers (13, 14) are in turn moved perpendicularly for taking the image on an inked block (23, 24) and for transmitting it to a part (33, 34).
