  • the primer can be applied simultaneously to the first and third CD on the recording of the carriage and subsequently after the transport of the carriage by the distance D2 on the second and fourth CD.
  • the resolution of the ink jet heads used in the printing stations 50a-50d may not be sufficient for the required print quality.
  • FIGS. 6-8 the design of the part of the printing device according to the invention for loading the receptacles 6 with objects to be printed on the carriage or for removing the printed objects from the receptacles of the carriages will be described.
  • the figures show an input and output station 150, which adjoins the left in the base member 10 shown in Figures 1 and 2, wherein the base member extends into the input and receiving station, so that the respective carriage can drive into it.
  • the parking position of the respective transport carriage or the respective holding plate in the input and output station is indicated by the reference numeral 140. In this position of its holding plate drives a carriage equipped with printed CDs.
  • the input and output station 150 has an input section arranged in the upper region of the illustration in FIGS. 6-8 and an output section arranged in the lower region of the figure.
  • CDs to be printed are stacked on four CD input disks 72, which centrally have a long spindle extending through the center hole of the CDs.
  • the CD input discs 72 are circumferentially disposed on an input carousel 70. After the CDs discarded on one of the CD input discs are removed, the input carousel rotates to the next filled CD input disc, which is then deflated.
  • the input section further comprises a collecting carriage 80, which has a receiving plate which is identical to that of a transport carriage.
  • the collecting carriage also CD recordings 82, which are arranged on the receiving plate in the same manner as those of the transport carriage to each other.
  • the collecting carriage can be moved stepwise parallel to the longitudinal extent of the parking position 140 of a transport carriage by means of a stepper motor 84.
  • the dispensing area has a singling carriage 90, which in turn, like the collection carriage, has CD receptacles, the spacing of the receptacle being again identical to that of a transport carriage.
  • the separating slide is also movable via a stepping motor 94 parallel to the collecting slide or transport slide. Collecting carriages and separating carriages are moved independently and stepwise in the described embodiment. The step size is determined by the distance between two receptacles 82, 92 on the respective carriage 80, 90.
  • accumulation carriages and singulation carriages are moved only within the input and output station.
  • the dispensing area has a receiving carousel 100 which includes four CD receiving plates 102 spaced circumferentially. Each plate in turn has a spindle on which the issued CDs are strung. If a CD-receiving plate is filled to the end of the respective spindle, the carousel 100 rotates to the next CD-receiving plate, which is subsequently filled with printed CDs.
  • each input CD is subjected to a so-called IdentCheck.
  • the IdentCheckteller 78 (FIG. 7) serves this purpose, to which the CD taken from a CD input disk is first placed and subsequently the identity of the relevant CD is detected. For this purpose, each CD has a code mark, which uniquely identifies the data content. If the verification of the identity of the respective CD reveals that it does not correspond to the set printing process, the CD is placed on the ejector 76.
  • a so-called PrintCheck is performed, in which the print quality is checked.
  • the CD to be checked is placed on a PrintCheck carousel 107, which is constructed in an oval shape and symmetrically to a rotational axis 109 of the carousel has two PrintCheckteller 108a, 108b.
  • the CD to be checked is placed on the plate, which is provided with the reference numeral 108a.
  • the PrintCheck carousel 107 rotates 180 ° with the axis of rotation 109 perpendicular to the plane of the drawing, causing the CD device in the receiving area of a camera 110, the recording of which is processed by the printing surface.
  • the PrintCheck carousel 107 rotates back to the starting position in which the tested CD is removed.
  • the CD is placed on one of the four CD-output tray 102, otherwise on the Ausschussteller 106.
  • the one or more color print heads are moved so that an optimal overlay of the single monochrome prints is achieved.
  • the individual color print heads are preferably mounted displaceably in a plane, wherein the heads can be readjusted in their position in response to the detected printing error by a control during operation of the device. Such readjustment may be necessary, for example, after a printhead change.
  • the storage of CDs in the input and output station 150 is performed by a CD transmitter 120 which is movably mounted on a horizontal strut 124 of a portal 122.
  • the movement of the CD transmitter 120 is perpendicular to the longitudinal extent of the carriages, for example the collecting carriage.
  • the CD transformer 120 is reciprocated stepwise in the direction of the arrow C, wherein the step size is equal in both directions and corresponds to half the distance of the center lines of the receptacles 82, 92 of the collecting tray or the separating slide. This step size is identical to the distance between the center lines of separating slide and collecting slide to the center line of the recordings of a transport carriage, as far as it is in the parking position 140 with its support plate.
  • the CD transmitter in the described embodiment has a total of twelve vacuum injectors with which the CDs can be picked up by suction.
  • two spaced straight by the pitch of the CD transmitter rows of injectors 126 are arranged in the central region of the transformer, which serve for simultaneously lifting the arranged on one of the three carriages CDs.
  • the lifted CDs are placed after moving the CD transmitter by one step length in the drawing plane down to an adjacent carriage.
  • the CDs arranged in the collecting carriage 80 can be picked up and stored in the transport carriage 16a, 16b or the CDs arranged in the transport carriage can be picked up and deposited in the singling carriage 90 in a single work step.
  • the CD transmitter 120 has two further injectors on the plate-shaped base both in the input and in the output region, one of which is pivotable. Due to the stepwise movement of the CD transmitter between two operating positions, a single point is assigned to each individual vacuum injector, from which CDs are recorded and a single point within the input and output station 150 on which CDs are stored. Only the injector 126, which is attached to the pivot arm 128 in the input area and the injector 126, which is attached to a pivot arm 127 in the output area, have two alternative storage locations, which are selected depending on the result of IdentChecks or checking the print quality.
  • FIG. 6 shows an operating situation in the input area in which, on the one hand, a CD is placed on the identification deck and the CD previously checked on the identification deck is placed on the collecting rack 80.
  • the separating carriage 90 still has two printed CDs.
  • the CD previously recorded by the separating carriage is placed on the print check plate 108a of the PrintCheck carousel 107, at the same time the pivoting arm 127 checks a positive result CD on a CD output tray 102 of the output carousel 100 from.
  • the collection carriage 80 moves one step to the right and the singulation carriage 90 one step to the left.
  • the CD transmitter 120 then clocks up by the described step size in the drawing figures, so that the operating situation shown in Figure 7 results.
  • the upper vacuum injector 126 in the input area is currently picking up a CD from the CD input tray 72, at the same time the vacuum injector 126 attached to the swing arm 128 receives a CD from the ID tray 78.
  • the outermost injector 126 on the pivot arm 127 picks up a CD checked for its print image while the adjacent vacuum injector picks up a CD from the singulation carriage 90.
  • the CD transmitter can step down one step, placing the checked input CD on the collection slide and the checked output CD on the output carousel.
  • the individual vacuum injectors of the CD transmitter work in the described embodiment in a common plane, ie, the CD transformer 120 moves as described stepwise only in one plane.
  • a CD lifter 74 is provided in order to bring CDs on one of the CD input disk 72, from which CDs are taken, in the receiving plane of the vacuum injector 126.
  • the described reciprocating movement of the CD transmitter on the one hand in a single step a retracted into the input and output station 150 transport carriage loaded with CDs to be printed or the printed CDs are removed.
