  • the present invention comprises a phase control system for the paddle wheel arrangement in the folder of a printing press, which first includes a rotating paddle wheel with a first plurality of paddle blades, a second rotating paddle wheel with a second plurality of paddle blades and a transport system for feeding the folded products into a product receiving area, as seen in the transport direction, in front of the paddle wheels, the paddle wheels being arranged in such a way as to each other, that the circumferential lines described by the blade tips of the first and second blade wheels partially overlap, and the blade wheel arrangement has a first sensor which detects a first edge of a folded product when it passes a first position and which, depending on this, generates a corresponding first signal, one second sensor, which detects a respective first airfoil when it passes a second position and which generates a corresponding second signal in dependence thereon, a processor which generates a he based on the first signal Calculated most point in time when the folded product reaches a predetermined reference position lying in the product receiving area, which determines the phase

  • a product receiving area is located on an intersection of the first and second paddle wheel circumferences. The product receiving area is designed such that only one of the first and second airfoils came to occupy the product receiving area at any given time.
  • the folded product transport system is intended for the conveyance of the folded products into the product receiving area; it can e.g. B. include a pair of high speed belts and / or a cutting cylinder assembly.
  • the phase control system includes a processor, a first sensor, a second sensor and a paddle wheel motor control switch.
  • the first sensor detects an edge of a respective folded product passing a first position and generates a corresponding first signal.
  • the first position is defined as the point at which a knife of the cutting cylinder arrangement cuts the folded product.
  • this first position can be determined at any point along the high-speed belts, in the product receiving area, or at any suitable location in the folder.
  • the processor of the control system calculates a first point in time at which a respective folded product will reach a target position in the product receiving area.
  • the second sensor detects each first airfoil when it passes a second position and generates a corresponding second signal.
  • the processor of the control system calculates the phase angle of the first or of the second airfoil, whichever occupies the product receiving area first.
  • the processor of the control system then calculates the phase difference between the current airfoil phase angle and the desired airfoil phase angle.
  • a display device can be provided, on which the phase angle or phase difference is displayed to the operator.
  • the speed of rotation of the impeller assembly is controlled by an impeller motor control switch.
  • the control system changes the speed of rotation of the impeller assembly based on the phase difference by sending control signals from the processor to the impeller motor control switch. By repeatedly changing the speed of rotation of the impeller assembly in this manner, the control system adjusts the current impeller phase angle to the desired impeller phase angle.
  • various factors can be used to set the desired phase angle. If e.g., if the products (i.e., the folded signatures) get from the high-speed conveyor belts to the impeller rotation too early, the rear end of the products can wrap around the airfoils and cause a jam in the impeller assembly. On the other hand, if the products are late in the paddle wheel rotation, there is not enough time for the products to slow down and they "crash" into the rear end of the pockets formed between the blades, damaging them. The degree of slowing of the products after their release by the conveyor belts depends on the inertia of the products and the friction between the products and the blades. Another problem is the damage to the pressure due to excessive friction between the signature and the airfoils. Based on these factors, a desired airfoil phase can be determined experimentally to avoid jams, crashes and pressure damage to the products.
  • the desired airfoil phase is changed based on usage and environmental parameters.
  • the friction between the products and the airfoils depends on various other factors, such as the weight and width of the paper used, the silicone content in the paper and the associated adhesion of the products in the machine.
  • the inertia of the products also depends on the web speed of the machine and the weight of the paper.
  • the degree of pressure-damaging friction changes with temperature and humidity. Consequently, it is advantageous to set the desired phase angle based on the values of one or more of these environmental and application parameters.
  • These parameters can either be entered manually on a control panel or measured automatically by sensors.
  • the desired phase angle corresponding to the various combinations of parameters can e.g. B. determined empirically or stored in a memory as an NxN matrix, where N is the number of parameters.
  • the suitable desired phase angles can then be read directly from the matrix by entering the current values of the parameters.
  • control system can be programmed to mimic the process steps performed by the human operator. For example, the manner in which an operator manually adjusts the impeller phase based on a number of different factors, such as web speed, temperature, paper type, or other environmental or usage parameters, can be monitored by the control system and automatically stored in a table in memory. The desired phase angle can then be read from the table based on the current environmental and usage parameters in the subsequent printing process.

  • 3b shows the signature 14.1 in position 1, namely at the point where it first contacts the tip 6.22 of the airfoil 202.
  • the tip 6.12 of the airfoil 102 is still away from the center line 15, and part of the signature 14.1 remains in contact with the high-speed bands 13. Since the signature 14.1 is still in contact with the high-speed bands 13, it moves continues with (approximately) the conveying speed W despite the friction caused by contact with the tip 6.22.
  • signature 14.1 bends slightly as it slides along the surface of airfoil 202, but travels at conveyor speed W due to its continued contact with high speed belts 13. In this position, position 2, the tip 6.12 of the airfoil 102 approaches the center line 15, but has not yet crossed the center line 15.

  • the degree of slowdown of the signatures after their release by the conveyor belts 13 depends on the inertia of the signatures and the friction between the signatures and the airfoils.
  • Another problem that arises is the pressure damage caused by excessive friction between the signature and the airfoil.
  • the moisture in the print shop can affect the degree to which the ink on the signatures 14 has dried when they leave the high-speed belts 13. This in turn can be done in one Relate to pressure damage caused by a given impeller phase.
  • the type of product, type of paper, adhesiveness and silicone content of the paper can also influence the desired impeller phase.
  • the tack which is defined as the amount of static electricity in the signatures, is a parameter that is conventionally regulated by a "stapler".
  • the amount of silicone added to the web can vary in conventional printing presses. The values chosen for the adhesiveness and the silicone also have an influence on the friction and inertia properties of the signatures when they enter the paddle wheel pockets 111 and 211.
  • the phase of rolling the belts 13 with respect to the paddlewheels 100, 200 was manually adjusted by monitoring the position of the signature upon entry into the paddlewheels with a measurement mark (or with the naked eye) and then the speed of the High-speed belts 13 was regulated accordingly.
  • This method of impeller phase adjustment has several disadvantages.
  • First, the manual adjustment of the speed of the conveyor belts 13 based on measuring marks is in itself imprecise, and it is therefore not possible to optimize the phase control in this way.
  • Another problem arises from the fact that it must be possible to change the speed of the folder in accordance with the change in the web speed of the printing press. because the web speed of the printing press can vary to a great extent.
  • This inventive vane wheel phase control system 300 shown in FIG. 4 includes an airfoil position sensor 310, a vane wheel motor 320, a web speed sensor 330, a signature position sensor 360, a processor 340 and a vane wheel motor control switch 350.

  • the signature position sensor 360 determines the position of the signature 14 and can be installed in various ways. It can e.g. B. a sensor relative to the cutting cylinder assembly 20 of the folder 1 can be attached. Since the folded web is cut by the cutting cylinder arrangement 20 into signatures 14, a sensor attached to this arrangement 20 can definitely determine the point in time at which the cutting cylinder generates a signature 14. Since the distance between the cutting cylinder and the high-speed belts 13 is known, and since the The speed at which the signature 14 moves after leaving the cutting cylinder must be substantially equal to the web speed of the printing press (which is sensed by the sensor 330) is the point in time at which the leading or trailing edge of a signature 14 the conveyor belts 13 leaves, determinable. Alternatively, the speed of the signature 14 leaving the cutting cylinder can be measured by the rotational speed of the cutting cylinder 20.
  • the signature position sensor 360 could be designed such that a marking is made next to each knife 401 of the cutting cylinder 20 and a sensor is placed next to the point at which the knife 401 contacts the recess 400 of the cutting cylinder 20.
  • the position of the front and rear edges of the signature 14 is known.
  • the speed at which the signature 14 will move from the cutting cylinders 20 through the high-speed belts 13 is equal to the web speed of the printing press, since any substantial deviation from the web speed would cause a paper jam.
  • the speed of movement of the signature 14 can be calculated more directly by monitoring the speed of rotation of the cutting cylinders 20 and the drive rollers of the high-speed belts.
  • the position of the rear edge of the signature 14 could be determined in the same way.
  • a sensor ie an optical sensor
  • a period of time between the leading edges of the signatures could be from the pulse signals emitted by the sensor and the time t 1 could then be estimated as the time of the last pulse plus the time period.
  • the illustrated method of determining airfoil position is described below with respect to airfoil position sensor 310, including markers 311 and mark sensor 312. As the impeller wheels 100, 200 rotate, the markers 311 activate the mark sensor 312. Since the shape of the airfoil is known, the position of the airfoil tip (or other part of the airfoil blade that is connected to the mark 311 that activates or triggers the mark sensor) can be easily determined at the point in time at which the sensor 312 is activated or triggered. Furthermore, the position of the airfoils at any time between pulse signals can be easily extrapolated from a set of two or more pulse signals. As a result, the position of the airfoil tip in the product receiving area 110 at time t 1 can be easily determined. Since, as shown in FIGS. 3a to 3h, only one blade tip occupies the product receiving area 110 at a given time, the signatures 14 are alternately output into the pockets of the blade wheels 100 and 200.

If a change in the phase angle is required, a signal is sent to the impeller motor control switch 350 to make the desired phase angle change.
