Definitions

  • the present invention relates to a method for Control the transportation speed of a transportation and Gathering track, in particular such a gathering track, used in a paper handling system.
  • Paper handling systems are mainly used by large companies, Banks, insurance companies, service companies etc. used. With these companies serve the paper handling systems, the transport and gathering lanes use for processing large Amounts of paper, such as invoices, reminders, bank statements, Insurance policies or checks.
  • the processing speed of the collating web of such known paper handling systems is according to the state the technology fixed or via controls an operator adjustable. With such devices the total speed of the collating path at a expected exceeding of a maximum stack height of the Filling goods for all items in the gathering path processed, lowered by the operator. This has a deterioration in the throughput of the collating path result.
  • the drives for the maximum acceleration torque, that for the collating path, for example of the paper handling system is required to be interpreted.
  • the drive design is oversized for these applications and charged with too high costs.
  • the drives for maximum processing performance with a limited filling strength and one limited product weight can be used in applications, in which a partially or constantly higher product thickness or a partially or constantly higher product weight occurs, the system only with a reduced processing speed operate.
  • a production cycle are often only in individual cases permissible for a maximum processing speed Limit values exceeded.
  • One over the entire production cycle reduced processing speed thus has a unnecessary reduction in processing power at one Paper handling system of inserting performance, as a result.
  • Object of the present invention is to provide a method for Adjustment of the transport speed of a collating lane through which the throughput of a processing plant, in which the collating track is built, improved can be.
  • This task is accomplished by methods of controlling the transport speed a collating track according to claim 1 and 7 solved.
  • the measure for each stack of product is preferably the number of sheets and / or the height and / or the weight of the stack of contents. If a measure exceeds an assigned setpoint, the processing speed, i.e. the transport speed the collating path, decreased until the Product stack, the dimension of which exceeds the setpoint, the Has left collision lane.
  • the collating path can be a plurality of one behind the other have arranged transport device modules, wherein each transport device module using its own motor is driven.
  • the product stacks are each from a rear transport device module in the direction of movement to a front transport device module in the direction of movement passed, each transport device module has at least one setpoint of its own, wherein the transport speed of all transport device modules is reduced if a dimension of a stack of goods is one Setpoint value of a transport device module on which the Product stack is located, exceeds.
  • Dimensions are overall dimensions for all on one transport device or a transport device module Filling stacks are determined, the transport speed is controlled on the basis of this overall measure.
  • the present invention provides a method of processing speed for example a paper handling system depending on the weight and height of the filling material in the paper handling system, i.e. the inserting system, adjust automatically.
  • a preferred embodiment the method according to the invention is used for adaptation the processing speed in a paper handling system, that works in cycles.
  • the single ones Cycles are referred to as insert clocks.
  • the Processing speed for each inserting cycle to the current loading of the paper handling system regarding the product height, also known as product thickness can be adjusted and the product weight.
  • Paper handling systems consist of the optimized processing speed when processing stacks of filling goods, the different processing quantities, i.e. different Heights or different weights.
  • the result is an improved price / performance ratio the drive selection.
  • the method of the present invention is as follows explained using an inserting system, but obviously is that with the method according to the present Invention any processing system can be operated can be transported with the product stack and with of the product units are added to the product batches.
  • FIG. 1 two transport modules A and B are shown, the form part of an inserting system.
  • the transport modules A and B have conveyor belts 100 on which slides and Stoppers are attached.
  • the sliders and stoppers are like this attached to the conveyor belt 100 that they each have compartments form in which stacked goods, i.e. Sheets of sheets, booklets or groups of sheets 110 can be transported.
  • the conveyor belts of the transport modules A and B are arranged in such a way that they overlap in an overlap area 125. This makes it possible for a stack of the product to be filled Transport module A is transferred to transport module B.
  • the conveyor belts of the transport module A are driven by a drive device, which is designated with motor 1, driven.
  • the conveyor belts of the transport module B are replaced by a Drive device, which is designated with motor 2, driven.
  • the motors, motor 1 and motor 2 have setpoints on, which indicate up to which filling strength and up to the filling weight of the conveyor belts at maximum speed can be operated. Exceeds the Filling strength or the filling weight of a to be transported The system must have a stack of these target values with a operate at lower processing speeds.
  • the motors, motor 1 and motor 2 are driven gradually, i.e. the stack of goods is transported each in envelope files.
  • an insert cycle is a stack of goods from a first stop transported to a second stop.
  • At every stop an insert station can be arranged.
  • a filling unit i.e. a single sheet or Booklets or groups of sheets, for a stack of contents, i.e. a stack of sheets already on the collating path is transported, added.
  • the Transport module A is at the entrance 150 of the same by means of a so-called collection and handover point an input stack 200 handed over.
  • the input stack 200 is still located in the collating path not on the transport module A.
  • the input stack can while being transported over the collating line different insert stations or any, in which Collars opening channels, additional filling units can be added, although not in the figures is explicitly shown.
  • the inserting system also has a control device and a data transmission line that works as a system fieldbus is referred to.
  • the control device is over the Plant field bus with every motor, for example motor 1 and the motor 2 connected.
  • the controller uses this information to the filling strength, i.e. the fill level, and the fill weight of each Sheet stack that transports on the collating path will calculate.
  • the control process available in which the speed specification the next insert cycle based on the input conditions, i.e. the filling strength and the filling weight all supplied filling units as well as the incoming stacks, can be calculated.
  • the control device thus detects a measure for all of the Filling unit fed filling unit, namely for the input stack fed to the collection and handover point as well as all fed to the various insert stations Product units.
  • the measure for every stack of product, added a filling unit at a stop is in the preferred embodiment before Insert cycle, in which the filling unit is the filling material stack is actually added from the insert station.
  • FIG. 1 shows the part of an inserting system, which is shown in Fig. 1, before the beginning of an inserting cycle 1.
  • the input stack 200 is at the entrance of the transport module A and is during the first inserting cycle handed over to the transport module A.
  • the entrance pile has a filling strength of two and a filling weight from 6 to as indicated by the labels "S: 2" and "G: 6" is shown.
  • At four stop points 1 to 4 of the transport module A there are four stacks of product while on four stop points 5 to 8 of the transport module B also there are four stacks.
  • 2 are two more Stops 9 and 10 are shown, but to a subsequent one Transport module belong and thus for the transport modules A and B are irrelevant.
  • Each of these Product stack at the stop points 1 to 10 has a certain one Filling strength and a certain filling weight.
  • Table I shows parameters of engines that are assigned to different transport modules of a collating path.
  • the two transport modules A and B, to which motor 1 and motor 2 are assigned, are shown in the figures.
  • the other motors 3 to 5 are not shown in the figures.
  • the table shows the stop points assigned to the motors, the limit value of the filling strength for a maximum speed Vmax and the limit value for the filling weight for the maximum speed Vmax.
  • engine Assigned stop points Fill level limit for Vmax Limit value fill weight for Vmax Motor 1 1,2,3,4 6 16 Motor 2 5,6,7,8 6 16 Motor 3 9.10 4th 12th Engine 4 11.12 4th 12th Motor 5 13.14 4th 12th
  • the limit or nominal value of the filling strength is for the engine 1 6. That is, if the filling strength of the on the transport module A, which is assigned to the motor 1 stack of goods transporting this limit or setpoint exceeds the transport speed of Vmax can be reduced to a lower value. The same applies if the filling weight of the goods to be transported Filling stack exceeds the target value for the filling weight, 16. This applies in the same way to motors 2 to 5 with respect to the limits that they have.
  • Table II shows the filling strengths and the filling weight of the stack of filling goods located at the respective stop points before the first inserting cycle. The sums of fill strengths and fill weights for the respective motors are also shown. Stop parts Value filling strength Sum for engine Value fill weight Sum for engine 1 1 5 6 15 2nd 1 2nd 3rd 1 3rd 4th 2nd 4th 5 1 5 6 15 6 1 2nd 7 1 3rd 8th 2nd 4th 9 1 2nd 6 8th 10th 1 2nd 11 1 3rd 3rd 7 12th 2nd 4th 13 1 2nd 6 6 14 1 2nd
  • the input stack 200 is fed during the inserting cycle 1.
  • the filling material stack 200 does not yet load the transport module A and therefore the motor 1 during the inserting cycle 1, since the same is fed through the collection and transfer point and still loads the same during the inserting cycle 1. No stop is therefore assigned to stop 1 in Table III.
  • Table III shows the occupancy of the various stop points 1 to 14 during the insert cycle 1, whereby during the input stack 200 is fed to this inserting cycle. During this inserting cycle, none of the limit values is the Motors 1 to 5 injured, as can be seen from Table III. The system is therefore operated with Vmax.
  • FIG. 3 shows the transport modules A and B at the end of the inserting cycle 1.
  • the stacks of contents were each moved one stop.
  • the product stacks that were previously at the stop points 2 to 4 are now at the stop points 3 to 5.
  • the input stack 200 is located at the stop point 1 and thus contributes to the load on the motor 1 is assigned to the transport module A at.
  • Table IV shows the loading of the stop points 1 to 14, as well the sum of the fill strengths or fill weights for each Motor before the end of the first insert cycle. As from table IV can be seen is the sum of the fill weights the stack of filling goods located at the stop points 1 to 4 17. Thus, the total fill weight for the engine exceeds 1 the limit value of the same, which is 16.
  • the control device presents this when comparing the sum of the fill weights the stack of filling goods located at the stop points 1 to 4 and the fill weight setpoint for motor 1. It then controls all motors at the next insert cycle to a reduced speed. The control device first controls the motors to speed Vmax if the sum of the fill weights of the stack of goods at the stop points 1 to 4 the fill weight limit of the engine 1 no longer exceeds, and no other Target or limit value is violated.
  • Table V also shows the parameters of the product stack at the stop points 1 to 14 as well as the sum of the filling strengths and the filling weights of the same for the motors 1 to 5.
  • This control process is based on an information model, in which each motor has a specific segment of the process image assigned. These segments correspond to the number of goods that transport one engine per cycle got to. It is therefore possible to use the for each individual motor Determine acceleration moments for the next cycle and thus the speed specification for the next cycle to determine.
  • the control procedure above regarding the input fill stack 200 when passing through a transport and collation lane without adding a filling unit to one Insert station can be any Use transport and collation lanes where filling units are used by means of an insert station a stack of contents to be added.
  • the fill strength for this stack of goods the next one is the original one Filling strength plus the filling strength of the filling unit, which is added using the insert station.
  • the fill weight of this stack is then the original one Filling weight plus the filling weight of the filling unit is added to the insert station.
  • the method according to the present invention is optimized consequently the transport speed within a collating path, for example an inserting system, depending on the height and / or weight of the product.
  • a collating path for example an inserting system
  • the transport speed within a collating path is based on the number or weight of the leaves up-to-date in a collection and handover point counted or counted, at which point within the gathering path which product stack height or which Product stack weight was reached, then current if a stack exceeds a limit, one Reduction of the working speed of the collating path is made.
  • a collating path consisting of different Transport modules can be used for the different transport modules operated by one motor each, to which different stop points are assigned, different limit values apply, whereby if the respective valid limit value only exceeded at a stop will, all engines at a lower speed must be reduced.
  • the procedure according to the present invention not on the back and forth Shifting between two speed levels at two Limits limits, but also includes one depending of calculated filling thickness sizes and / or filling weight sizes graded cruise control, where then the transport device or each transport module several Setpoints assigned for fill weight and fill height are.
  • the method according to the present invention is thus both applicable to collation lanes that are created by only one Motor driven, as well as on modular gathering lanes, where individual transport modules by each own engines are driven. In the latter Fall need if a limit value of an engine is exceeded will, all engines at a lower speed be reduced.
  • the invention becomes at least one dimension of a stack of contents compared with a target value.
  • an inserting device can be the number of sheets, the height and / or the weight of the product stack can be used.
  • According to the present Invention can compare each of these measures to a target value be, if any of these dimensions match the assigned Setpoint exceeds the transport speed the transport and collation unit down regulated becomes. It is obvious that it is also possible just one measure or a larger number of measures for each Stack of product to be used.
  • the invention provides overall dimensions for all stacks of contents, that of the engine of a conveyor are transported, determined. These dimensions can be at a Inserting system the total number of sheets, the total height and / or the total weight of those transported by this engine Be stacked. Again, any number of these Overall dimensions with associated setpoints that this motor are assigned to be compared.
