Definitions
- the invention relates to a device for drawing in an endless web, wherein a gripping device transports the beginning section of the endless web from an input section for the endless web to an output section.
- the invention further relates to a printing or copying system and a module.
- the invention further relates to a combined monitoring device.
- High-performance copiers are used, which can handle extensive and complex print jobs or copy jobs. Such systems are relatively large, so that they are broken down into several machine modules that are easy to transport. The various modules are put together by the user to form a printing system or copying system. Such high-performance printing systems or copying systems are described, for example, in WO 98/39691 by the same applicant. This document is incorporated by reference into the disclosure content of the present application.
- Another advantage of a modular concept in which, for example, a printing system is divided into a printing module and a fixing module, is the increased flexibility. In this way, an existing print module can be combined with different types of fixation modules, the prerequisite for this being a defined common interface.
- further modules processing record carriers can be used, which can be put together in a variety of other modules.
- JP-60-99655 A with abstract describes a device for drawing in an endless paper web, in which this endless paper web is drawn through several device modules arranged one behind the other. Each device module has its own traction device that circulates within the module. When the continuous web is passed through several modules, the beginning section of the paper web is transferred to the traction means of the next module at the boundaries of the respective module.
- a traction means is provided in each module, with the aid of which a gripping device for gripping an initial section of the endless web can be transported from an input section to an output section of the respective module.
- the two traction devices face each other genüber.
- a separable connecting device connects both traction means, so that in the connected state of the traction means a traction means which is continuous for both modules is created and the gripping device can transport the beginning section of the endless path from the input section of the first module to the output section of the second module.
- both traction means can be detached from one another again, so that both modules can be transported separately to another location.
- the invention thus provides an apparatus which allows an endless web to be drawn in automatically through two or more modules.
- the device is simple in structure and requires uncomplicated handling. If more than two modules are connected to one another, a plurality of connecting devices must be used at the module boundaries to create a continuous traction means, which connect the respective traction means in the modules.
- Another aspect of the invention relates to a printing or copying system which is equipped with the described modularly constructed feed device.
- a module is specified as part of a printing or copying system, the module being connectable and detachable from one another with an additional module at an interface, with a traction means, with the aid of which a gripping device for gripping an initial section of the endless web can be transported from an input section to an output section of the module, and with a part of a connecting device by means of which the traction means of the two modules, which are opposite one another at the interface, can be connected to and detached from one another. If several modules are equipped with such a feed device, these modules can be connected to one another which enables an automatic drawing of an endless web through the various modules.
- Another aspect of the invention relates to a combined monitoring device, wherein 'is signaled to large tensile force of the traction device falling below a too small tensile force of the traction means and exceeding a.
- the tension of the traction means in the device arrangement consisting of several modules can also be regulated.
- the combined monitoring device contains a first tensioning device and a second tensioning device, each of which is acted upon by spring forces in the direction of the axis of the traction means.
- One tensioning device is moved out of a limit position by traction means; when the tractive force of the traction device is exceeded, the other tensioning device is moved out of a limit position.
- a position sensor detects that the tensioning devices move out of the limit positions and generates signals, whereupon the drive units for the traction device can be switched off.

- the transport route for the endless web 12 is in
- Figure 2 is not shown for reasons of clarity; however, it runs in a manner similar to FIG. 1 from an input section 70 of the first module 60 to an output section 72 of the second module 62 along transport rollers 74 for the endless web 12, to which deflection elements 76 for guiding the cables 66, 68 are assigned.
- a gripping device 78 can be moved by the ropes 66, 68 from the input section 70 to the output section 72. As will be described in greater detail below, the gripping device 78 grips an initial section of the endless web 12 and transports this initial section from the input section 70 of the first module 60 to the output section 72 of the second module 62.
- a first stepping motor 80 is arranged as a drive unit within the printing module 60 and drives a first winding roller 82, onto which the cable 66 is wound or from which the cable 66 is unwound.
- a second stepping motor 84 is connected in the same way as a drive unit to a second winding roller 86, which winds up or unwinds the cable 68.
- Both stepper motors 80, 84 are preferably controlled synchronously with one another, ie the winding or unwinding of the cables 66, 68 takes place synchronously.
- other motors can be used that are precisely positioned can be used, eg motors with incremental encoders that are controlled incrementally.
- the pressure module 60 contains a tensioning means 88 with position sensors for each rope of the rope pair 66.
- This tensioning means 88 generates a rope tension for the rope 66 when the modules 60, 62 are disconnected.
- this tensioning means 88 When the modules 60, 62 are connected, this tensioning means 88 generates the required rope tension for the then connected ropes 66, 68 and is also used to control the stepper motors 80 , 84 with the help of the control module 90.
- a first monitoring unit 92 and a second monitoring unit 94 are provided for each cable 68, which are connected to control modules 96 and 98, respectively.
- the first monitoring unit 92 monitors the rope 68 for exceeding a maximum tensile stress.
- the second monitoring unit 94 monitors the rope 68 for falling below a minimum tension.
- the monitoring units 92, 94 each contain a position sensor, e.g. a microswitch that monitors the position of a spring-loaded deflection roller around which the respective cable 68 is guided.
- the position of this spring-loaded deflection roller changes, which is signaled to the control modules 96, 98 by the microswitch.
- an overload for example as a result of a blockage of the cables 66, 68, or an underload, for example if the endless web or the cables 66, 68 breaks, can be identified and signaled as an operating error.
- the monitoring units 92, 94 also provide the required rope tension for the ropes 68 in the module 62 in the case of separate modules 60, 62.
- control modules 90, 96 and 98 are preferably implemented in software.
- a The control system evaluates the supplied signals and generates • the necessary displays and control commands.
- FIG. 3 shows a schematic drawing of the interface 64 between the two modules 60, 62 in different operating phases.
- the two modules 60, 62 with the two ropes 66, 68 face each other.
- the ropes 66, 68 are connected to one another on a connecting device 100.
- This connection device also carries the gripping device 78, as will be explained in more detail below.
- the structure of the connecting device 100 can be seen in the middle part of the figure in FIG.
- the connecting device 100 contains a first cross member 102 and a second cross member 104 which can be connected to one another or separated from one another at a separating surface 106.
- the crossbeams 102, 104 have specially shaped shaped elements 108, 110 at their ends, which serve to smoothly guide the connecting device 100, which also carries the gripping device 78, on its way through the two modules 60, 62. Both shaped elements 108, 110 can also be separated on the separating surface 106. It is pointed out that the gripping device 78 can also be arranged separately from the connecting device 100.
- the ropes 68 of the fixing module 68 are detachably fastened to the second cross member 104 in a fastening opening 114.
- the ropes 66 of the printer module 60 are also detachably fastened in fastening openings 112 of the first cross member 102.
- the ropes 66, 68 are suspended in the fastening openings 112, 114 with clamping sleeves attached to them.
- the two cross members 102, 104 are connected to one another in the connected state by means of fastening elements, for example screws (not shown).
- the state in which the two modules 60, 62 are detached from one another is shown in the lower part of FIG. 3.
- the two cross beams 102, 104 of the connecting device 100 are detached from one another at the dividing line 106, for example by loosening the connecting screws.
- the first cross member 102 is received in a first holder 61 and is pivoted upward in the direction of the arrow 116 about a pivot axis 118 within the printer module 60. In this way, the first cross member 102 is received within the module 60 so that it does not protrude beyond the boundary plane of the module 60 which faces the fixing module 62.
- the pivoting about the pivot axis 18 takes place in such a way that the cable 66 remains essentially length-neutral, ie no additional
- the second cross member 104 is also held in the fixing module 62 in a second holder 63 in such a way that it does not protrude beyond the boundary plane of the module 62 which faces the printer module 60.
- the ropes 66, 68 remain anchored in the fastening holes 112, 114 and are kept under tension by rope tensioners in the respective modules 60, 62.
- the cross members 102, 104 are locked in the respective brackets 61, 63.
- the pivoting of the first cross member 102 has a further advantage. Due to the length of the swivel arm, which is preferably adjustable, a possibly smaller predetermined distance between the two modules 60, 62 can be bridged. As an alternative to a pivoting movement, however, it is also possible in another exemplary embodiment to translate the two cross members 102, 104 towards one another. A length memory for the ropes 66 or 68 may then be required. To connect the two modules 60 and 62, the cross member 102 is pivoted against the direction of the arrow 116 about the pivot axis 118 onto the second cross member 104 in the module 62. The two cross members 102 and 104 are then connected to one another.
- the connecting device 100 is moved to the module boundary, so that the cross members 102, 104 are positioned relative to the brackets 61, 63.
- the cross beams 102, 104 are locked in these brackets 61, 63. Since the cables 66, 68 in each module 60, 62 are under tension even in the released state, there are no loose ends of the tension elements at the interface.
- the ropes 66, 68 therefore assume a defined stable operating state, as a result of which operating errors are avoided.
- FIG. 4 shows a perspective illustration of the two cross members 102 and 104 in a state in which they are detached from one another.
- the second cross member 104 takes several
- Gripping elements 120 of which only one is shown in FIG. 4.
- the entirety of the gripping elements 120 forms the gripping device 78, which is thus carried by the connecting device 100 as a whole.
- the gripping elements 120 fit into openings 124 in the first cross member 102.
- Each gripping element 120 has a mouth-shaped opening 122 for receiving the starting section of the endless web 12. This starting section is held in the gripping elements 120 so that it can be transported through the modules 60, 62 ,
- FIG. 5 shows an essential part of the clamping means 88
- a deflection roller 130 which guides the cable 66 in a wrap angle of approximately 180 °.
- the deflecting roller 130 has a roller axis 132 which is guided in a longitudinal guide 134 so as to be displaceable along a longitudinal axis together with a movable slide 136 on a roller 138.
- the longitudinal guide 134 is embedded in legs 140 of a holder 142.
- the roller axis 132 is biased on both sides by tension springs 144 in the direction of the axis 146.
- the pre-tension can also be generated by a compression spring, which then acts accordingly on the deflection roller 130.
- two Hall generators 148, 150 are arranged, which interact with a plurality of permanent magnets, two of which are designated 152.
- the permanent magnets 152 are also moved with the movable slide 136 when the deflection roller 130 is deflected.
- the magnets 152, together with the Hall generators 148, 150 posi- tion ⁇ sensors, which signal the displacement of the deflection roller 130th
- the magnets 152 are preferably arranged such that the Hall generators 148, 150 signal a minimum or a maximum deflection of the deflection roller 130.
- an arrangement with a single elongated permanent magnet can also be used, the effective magnetic field of which is normal Operating position of the deflection roller 130 influences both Hall generators 148, 150.
- FIG. 6 schematically shows four states of the deflection roller 130, which are reproduced by the signals of the Hall generators 148, 150 when using an elongated permanent magnet. These signals are evaluated by the control module 90 (cf. FIG. 3), which in turn has a controlling effect on the stepper motors 80, 84.
- the deflection roller 130 and the slide 136 with the permanent magnet are in a normal position, in which both Hall generators 148, 150 detect the magnetic field of the permanent magnet.
- the deflection roller 130 is deflected upwards in a first position and downwards in another position. Both positions are just detected at their limits by the Hall generators.
- the respective deflection upwards or downwards is so great that only one Hall generator 148 or 150 detects the respective position.
- the deflection roller 130 is deflected upwards or downwards to such an extent that the respective detection range of the Hall generators 148 and 150 is left.
- a first monitoring unit 92 and a second monitoring unit 94 are provided in the fixing module 62 for each cable 66. Proper operation is monitored using the control modules 96 and 98 assigned to them. If there is a maximum tension, For example, if a rope tension greater than 100 N is determined, a microswitch contained in the monitoring unit 92 is triggered. The control module 96 then turns off the motors 84 and 80. If the second monitoring unit 94 detects that the tension falls below a minimum, for example when the paper web breaks, a microswitch is also triggered. The assigned control module 98 then causes the motors 84, 80 to stop. For example, when the rope tension falls below 12 N, the engine stop is triggered.
- FIGS. 7 to 10 show an exemplary embodiment for a combined monitoring device 160, which combines the functions of the monitoring units 92, 94 in a single device. The same parts are still labeled the same.
- the combined monitoring device 160 shown in FIG. 7 has a U-shaped frame 162 with a base 164 and two legs 166, 168. These legs 166, 168 of the frame 162 contain elongated holes 170 on both sides, in each of which pins 172 are guided (in FIG. 7 only one pin 172 can be seen) or a single continuous pin 172 projects into both elongated holes 170.
- a first tension spring 174 or tension springs for high cable force act on the pin 172, which tension pin 172 on both sides in the direction of a further pin firmly connected to the leg 168 176 pulls.
- the pin 172 is connected to a first slide 178, which serves as a first clamping device and is U-shaped.
- the first carriage 178 has an elongated hole 180 on each of its two legs, in each of which a pin 182 or a continuous pin 182 is guided.
- This pin 182 is preferably connected on both legs to the end of a second tension spring 184 for small cable force, which is firmly connected to the first slide 178 via a further pin 186.
- the pin 182 movable within the elongated hole 180 is fixedly connected to a second slide 188 serving as a second tensioning device, which carries the deflection roller 130 on the axis 132.
- An elongated Hall magnet 190 is arranged on the second slide 188.
- a Hall sensor 192 is arranged on the leg 168 of the frame 162.
- a guide pin 194 engages in the elongated hole 170 and is fixedly connected to the first slide 178.
- the guide pin 194 lies against a stop 196 and thus limits the movement of the first slide 178 in the direction of the base 164.
- the second slide 188 also carries a guide pin 198 which is guided in the slot 180. Its movement to the left is limited by a stop (not shown) in slot 180.
- a stop 200 limits the longitudinal movement of the second slide 188 relative to the first slide 178. In the normal operating position shown, the pin 182 bears against the stop 200. Likewise, the guide pin 194 bears against the stop 196.
- first tension spring 174 pushes the first slide 178 in the direction of the base 164 up to the stop 196; a rope (not shown) which is guided around the deflection roller 130 has such a great tensile force on the deflection roller 130 that the second carriage 188 follows in the direction of FIG is deflected to the right as far as possible and the pin 182 rests on the stop 200.
- the tensile force of the first tension spring 174 is greater than the tensile force of the rope, which acts on the deflection roller 130.
- the tensile force of the second tension spring 184 is less than the tensile force of the rope.
- the second tension spring 184 pulls the second slide 188 and the deflection roller 130 in the direction of the base 164 and thereby tensions the rope. If the cable force drops further, for example less than 12 N, the Hall magnet 190 on the second carriage 188 is moved so far in the direction of the base 164 that it moves out of the detection range of the Hall sensor 192. The Hall sensor 192 signals this state, whereupon the motors 80, 84 are stopped and the transport of the gripping device 78 is interrupted. This condition can e.g. occur when the guided rope breaks.
- the first tension spring 174 is tensioned and the pin 172 is deflected in the direction of the deflection roller 130 up to the stop 173 at the maximum, with the rope being yielded.
- the Hall magnet 190 which reflects the position of the deflection roller 130, is moved out of the detection range of the Hall sensor 192 to the right, which triggers a corresponding signal that the motors 80, 84 to Stopping brings. The transport of the gripping device 78 is thereby stopped. This operating state can occur if the gripping device 78 is blocked during its transport.
- the position of the Hall sensor 192 relative to the Hall magnet 190 and the length of the Hall magnet 190 determine this
- FIG. 8 shows various operating states of the monitoring unit 160.
- the leg 168 of the frame 162 contains elongated holes 202 in the direction of the axis of the cable 66.
- the frame 162 can be mounted in the module 62 (see FIG. 2) so that it can be adapted to the rope length of the rope 66 by simply moving the frame 162.
- normal operation is
- the deflection of the deflection roller 130 is illustrated using the reference axis 204. In the middle part of the picture the rope tension in rope 66 is too low; the deflection roller 130 is deflected to the left by the reference axis 204. The pin 182 is no longer in contact with the stop 200. The Hall magnet 190 leaves the detection range of the Hall sensor 192, which signals this operating state.
- the rope tension of the rope 66 is too great.
- the deflection roller 130 is deflected to the right by the reference axis 204.
- the tension spring 174 for high cable force is tensioned and the pin 172 is deflected to the right.
- the Hall magnet 190 leaves the detection range of the Hall sensor 192 to the right, which signals this fault condition.
- the combined monitoring unit 160 according to FIGS. 7 and 8 can also take over the function of rope tensioning for the rope 66. For this it is necessary that at least one pin 182 or 194 is not connected to the associated attachment within a control range for the rope tensioning. beat 200 or 196 is present.
- FIG. 9 shows the regulation of the rope tension using a diagram.
- the axis 132 of the deflection roller 130 can move back and forth within a control range 210, a predetermined cable tension being provided by the combined spring force of the first tension spring 174 and the second tension spring 184.
- both springs are symbolically represented as a spring F.
- the position 212 of the axis 132 drawn in denotes a desired position within the control range 210.
- the axis 132 moves to the left in FIG. 9. This movement to the left is brought about by the second tension spring 184, the travel of which is indicated by the arrow F1 between a first position 214 and a second position 216 is defined.
- the first position 214 is determined by the stop of the pin 182 on the stop 200.
- the second position 216 is defined by a stop of the guide pin .198 within the slot 180 (not shown in FIG. 7).
- a path 218 outside the control range 210 is provided, within which the motors 80, 84 (cf. FIG. 2) are to be switched off.
- the axis 132 of the deflection roller 130 is moved to the right in FIG. If the position 214 is reached and overcome, in which the guide pin 182 lies against its stop 200, the first tension spring 174 is deflected. In FIG. 9, the spring travel of this first tension spring 174 ' between the position 214 and a position 220 is designated F2.
- the position 220 is defined by the abutment of the pin 172 against the stop 173. This results in a switch-off path 222 when leaving the control range 210.
- the assembly consisting of Hall magnet 190 and Hall sensor 192 and the additional control elements must be designed such that a safe shutdown of the motors 80, 84 takes place within the path 222.
- these motors 80, 84 are controlled so that the axis 132 within the control area 210 remains.
- the position of the axis 132 is signaled by the arrangement of the Hall magnet 190 and Hall sensor 192.
- the motors 80, 84 are then controlled accordingly within a control loop.
- the desired position should the axis 132 of the deflection roller 130 selected to 212, that the second tension spring 184 having the small spring force of a relatively small distance, typically 5 mm to 10, up to the right stop, ie the distance between positions 212 and 214 must be selected accordingly.
- FIG. 10 schematically shows a variant in which compression springs 206 and 208 are used instead of the tension springs 174 and 184.
- the cable 66 which is guided around the deflection roller 130, does not have to be threaded into the space between the second carriage 188 and the deflection roller 130. This enables easier handling when inserting the rope 66.
- the first compression spring 206 for high rope force acts on the second carriage 188 in the example according to FIG. 10, so that the pin 182 rests against the stop 200 during normal operation.
- the second compression spring 208 for the small rope force acts on the pin 172, which is shown in its maximum left position in FIG. 10. If the rope force in the rope 66 is reduced, the deflection roller 130 and the pin 172 move to the right in FIG. 10. If the rope force is too great, the deflection roller 130 and the pin 182 move to the left in FIG. 10. The shifting of this position is signaled as in the example according to FIG. 7 by the arrangement of Hall magnet 190 and Hall sensor 192.
- leaf springs or other spring elements can also be used to implement the spring tension for the two slides.
