Definitions

  • the invention relates to a machine for printing on textile workpieces of a certain format, such as carpet tiles, towels or the like, in a pass with one or more application units arranged above a printing plane, such as rotary printing or spraying units, and with a transport device passing underneath them
  • Driver masks are arranged for receiving one workpiece each and which includes an input station in front of the application units and an output station behind the application units.
  • the transport device for the masks into which the textile workpieces are inserted for the printing process consists of a conveyor belt deflected near the input station and the output station via deflection rollers.
  • the masks must be made of a flexible material in order to be able to take part in the constantly changing bending and stretching of the conveyor belt. For this reason, the masks are attached to the conveyor belt using an adhesive that is selected so that the adhesive points also remain elastic.
  • the throughput speed of the conveyor belt is matched to the application speed, in particular to the circumferential speed of the printing cylinders of rotary printing units, the division dimension under which the driver masks for the workpieces are placed on the conveyor belt at a distance from one another must also be taken into account.
  • the printing or dyeing machines of the known type only work satisfactorily as long as the individual driver masks maintain the predetermined position on the conveyor belt. Because of the constantly changing bend and stretching of the conveyor belt in operation, changes occur both in the driver masks themselves and in their relative position to the conveyor belt, which lead to repeat errors on the printed workpieces.
  • the invention is therefore based on the object of designing the transport device for the driver masks in a machine of the generic type in such a way that a high repeatability is always guaranteed.
  • driver masks are arranged on the top on individual, rigid mounting plates which can be moved between the input station and the output station on a guide parallel to the pressure plane, with a first lifting device at the output station a second lifting device and a return transport device for the receiving plates is arranged between the input station.
  • the particular advantage of the machine according to the invention is that the driver masks for the workpieces are immovably fixed on the rigid mounting plates, which ensures a high repeat accuracy in the area of the printing units, provided a synchronized relative movement of the transport plates and, for example, the rotary printing cylinders.
  • the return transport device is expediently arranged in the machine frame below the feed guide, on which the transport plates are guided past the printing units close to the printing plane. Accordingly, the lifting device located at the output station lowers the transport plates, while the lifting device located at the input station lowers the transport plates the return level up to the pressure level.
  • the pick-up or transport plates are briefly stopped so that the workpieces can be inserted or removed from the driver masks on the top of the pick-up plates by hand or by machine.
  • the transport plates have special driver devices which, at least in the area of the application units, come into engagement with drive devices which convey the receiving plates under the printing units in a movement synchronized with the application speed, such as the peripheral speed of the printing cylinders.
  • toothed racks can be arranged on the underside of the receiving plates in the conveying direction, which engage with gearwheels or screws that are arranged below the feed plane in the machine frame in the area of the printing units.
  • Additional auxiliary drives can be arranged between the conveyor line below the application units, on which the mounting plates are transported in synchronized movement with the printing cylinders, and the input station, on the one hand, and the output station, on the other, which accelerate the mounting plates from a standstill or brake to a standstill and bring to the synchronized speed in the printing area.
  • the recording plates can be continuously conveyed past one another beneath the printing units in order to be transported away from the input station or to the output station by means of higher speeds which are applied by the auxiliary drives. Due to the additional acceleration the receiving plates are then given sufficient time for a brief stop at the input position and the output position.
  • a rotary printing press with a machine frame 1, on the top of which there is the so-called printing plane is located above which one or more printing units 2 with rotary printing cylinders 3 are arranged on the machine frame 1.
  • a guide 4 is arranged on the upper side of the machine frame 1 near the printing plane, on which mounting plates 5 can be transported from an input station 6 under the printing units 2 to an output station 7.
  • the receiving plates 5 are rigid in themselves and carry on their top a driver mask 8 which is matched to the circumferential format of the carpet tiles to be printed in each case.
  • the driving mask 8 can be made in one piece with the receiving plates 5, they essentially form a frame running along the edges of the plates.
  • the receiving plates 5 After each advance, the receiving plates 5 must be returned from the output station 7 to the input station 6.
  • a return transport device 11 not shown in detail in the drawing, is used, which can be a further guide for the upper guide 4 .3 for the receiving plates 5, along which the receiving plates 5 are conveyed by auxiliary drives.
  • the receiving plates 5 At the output station 7, the receiving plates 5 have to be lowered from the conveying plane of the advancing direction for the printing process into the lower level of the return transport device 11, for which purpose a lifting device 9 is used.
  • the receiving plates 5 Below the input station 6, the receiving plates 5 are then released from the return transport device 11 to the lifting device 10, which lifts the receiving plates 5 again up to the level of the guide 4 for forward transport.
  • the drive gears 13 arranged below the guide 4 ensure the feed of the receiving plates 5, which feed is synchronized with the peripheral speed of the printing cylinders 3, come into engagement with the toothed racks 12, which are arranged on the underside of the mounting plates 5 in the feed direction.
  • Fig. 3 shows that the drive gears 13 can be coupled to the drive of the printing cylinder of the printing units 2, for which purpose the drive gears 13 with other gears 15 are seated on a common shaft 14 and via the further gears 15 and thus meshing gears 16 the rotating cylinders Printing units 2 are driven.
  • the receiving plates 5 are conveyed along the guides 4 by means of driver devices 18, the details of which are shown in FIGS. 4 and 5.
  • the receiving plates 5 have lateral recesses 17 which may have the shape of a V-shaped vertical groove.
  • a driver member 19 can be brought, which has the shape of a roller and is actuated via a piston rod 20 by a lifting cylinder 21 which displaces the driver member 19 substantially transversely to the direction of advance of the receiving plates 5.
  • the driver member 19 is also connected to a strut 22 which is attached obliquely to the direction of travel and which is fixed to the carriage 24 carrying the driver device 18.
  • the strut 22 is connected in an articulated manner at both ends to the driver member 19 or the slide 24 and a further articulated mounting of the piston rod 20 or the cylinder 21 enables the driver member 19 to be displaced transversely. As a result of the support strut 22, high acceleration and deceleration forces can also be exerted on the Recording plates 5 are transferred.
  • Fig. 5 illustrates that the driver device 18 is mounted on two carriages 24 on two mutually parallel guide rods 23 which are arranged in the machine frame parallel to the guide 4. A synchronism is ensured between the upper and the lower slide 24 via a cross strut 25 which has an elongated hole 26. A driver pin 27, which is moved on a circular path and which is arranged on a suitable drive device, engages in this elongated hole 26.
  • the receiving plates 5 have on the two sides, which are in the conveying direction, vertical end slats 29, on the side of which a guide rod 29 is arranged, which is in the guide direction.
  • a plurality of roller bearings 30 are fastened to the machine frame in the longitudinal direction on both sides, each of which has three or more rollers 31, 32, which are arranged around a guide channel, the periphery of which is determined by the circumference of the guide rods 29 on the mounting plates 5.
  • the lower support roller 32 is pivotable in the roller bearings 30 lying in the region of the lifting devices 9, 10 Machine frame mounted and connected, for example, via an axle bolt 33 to a corresponding swivel drive.
  • the removal of the workpieces from the driver masks 8 of the mounting plates 5 is facilitated by lifters 34, which are shown in detail in FIG. 7. It is a plate or a plurality of webs which are recessed flush in the transport position in the top of the receiving plates 5.
  • the receiving plates 5 have corresponding top-side receptacles 35 in the area of the masks 8.
  • the lifters 34 have plungers 36 attached on the underside, which penetrate downward through the receiving plates 5 and carry support rollers 37 on their lower end. The lifters 34 thus run into a cam-like overrun element 38 in the region of the dispensing station 7, as a result of which the lifters 34 are raised above the top of the receiving plates 5.
  • the workpieces located in the driver masks 8 are raised so far with freely hanging edges that they can be handled comfortably and quickly removed from the receiving plate 5 at the output station 7.
