Description

  The present invention relates to a design support system, a paper transport simulation method, a program, and a storage medium for designing a paper transport path of an image forming apparatus represented by a copying machine, a printer, a FAX, and the like.

  In recent years, various simulations for handling mathematical models on a computer for the purpose of supporting machine design have appeared due to the improvement of computer performance. In general, rather than making many so-called prototypes in actual product development and repeating the study, examining product functions under various conditions before building the prototype reduces development time and development costs. Connected. Furthermore, from a macro perspective, it also leads to resource savings.

In the simulation, some analysis systems (design support systems) for analyzing the paper behavior in the paper conveyance path of the image forming apparatus have been proposed. For example, there are Patent Document 1 to Patent Document 3. Both proposals are intended to verify how the paper, which is the analysis model, passes with respect to the set transport conditions, paper transport guide shape, and transport roller shape and position. . By letting the designer understand the paper behavior, it contributes greatly to the support of the design act.
Japanese Patent Laid-Open No. 11-195052 JP-A-11-116133 JP 2004-189436 A

  However, when the design related to the paper conveyance in the image forming apparatus is actually performed, the optimum design cannot be performed in all aspects as long as the paper behavior can be accurately grasped. In actual product design, it is not possible to neglect how the paper behaves depending on the guide shape in the paper transport path. However, more importantly, the degree of change in the paper behavior is important when the guide shape and position fluctuate within design tolerances, and the shape of the paper itself, such as curl, fluctuates.

  For example, as shown in FIG. 2A, consider a case where the relationship between the guide 21 and the transfer portion of the guide 22 is optimized with the setting that the paper S is being conveyed in the direction of the arrow by the conveyance rollers 23 and 24. .

  In the conventional analysis system, the leading edge curl shape of the paper S or some physical property values of the paper S have been given to the guide 21 and the guide 22 created by the analyst or designer. Alternatively, the shape of the guide 21 or the guide 22 is determined by swaying the shape or the position of the guide 21 or the guide 22 with respect to the worst expected curl shape or the physical property value of the paper.

  Further, as shown in FIG. 2B, the position deviation of the unit 25 is roughly predicted, and the case where the stability of the paper behavior is considered to be the worst and the paper curl is considered to be the worst is the designer or analysis. Set by empirical knowledge and perform pinpoint analysis. Then, the tolerance for jamming was inferred.

  It can be said that the determined guide shape is almost optimal. However, in order to recognize objectively and accurately where the design tolerance range is within the allowable range for preventing jamming, an analyst has to execute all possible combinations.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a flowchart showing a procedure of paper conveyance (behavior) simulation processing in the design support system according to the embodiment of the present invention.

  As shown in FIG. 1, the paper conveyance simulation process includes 12 processing steps from Step S101 to S112.

  FIG. 3 shows a configuration example of a screen displayed in each of these steps. The screen mainly includes a menu bar 1 for switching display contents, a sub-configuration menu 2 for each display contents, a graphical screen 3 for displaying defined transport routes and results, output of system messages, and numerical values as required. The command field 4 is used for input.

  Hereinafter, each processing step in the flowchart of FIG. 1 will be specifically described.

  First, the conveyance path definition process of step S101 (conveyance path definition means) will be described. When the “transport route” button in the menu bar 1 is pressed to define the transport route, a sub-configuration menu 2 for transport route definition processing is displayed as shown in FIG.

  The sub-configuration menu 2 shown in FIG. 3 includes a roller pair definition button 2A for defining a pair of transport rollers with two rollers, a roller definition button 2B for defining one roller independently, and a straight guide definition for defining a straight transport guide. It has a button 2C.

  The sub-configuration menu 2 includes an arc guide definition button 2D for defining an arc conveyance guide and a spline guide definition button 2E for defining a conveyance guide with a spline curve.

  The sub-configuration menu 2 includes a flapper definition button 2F for defining a flapper (point) for branching a path along which the flexible paper is conveyed, and a sensor for detecting whether the flexible paper is at a predetermined position in the conveyance path. Has a sensor definition button 2G. In this way, the components for configuring the conveyance path of the actual image forming apparatus are prepared.

  When these component parts are defined by the sub-configuration menu 2, the position and shape of the defined conveyance path are reflected on the graphical screen 3.

  When the conveyance path definition process (S101) is completed, the process proceeds to a guide (conveyance guide) position movement condition setting process in step S102 (movement condition setting means). As shown in FIG. 4, the transition to the guide position movement condition setting process is performed by pressing the “movement definition” button in the menu bar 1, and at the same time the definition of the moving object is displayed in the sub-configuration menu 2. The movement amount (pitch amount) setting in the X direction and the Y direction is displayed.

  The definition of the moving object is an operation of determining a member to be moved in order to determine the jam occurrence boundary by changing the relative positional deviation of the single guide member or the entire unit. Details of the determination method for the jam occurrence boundary will be described later. Here, the movement amount is set to 0.2 mm in both the X direction and the Y direction.

  When the guide position movement condition setting process (S102) is completed, the process proceeds to a paper model creation process in step S103 (paper model creation means). The transition to the paper model creation processing is performed by pressing the “paper definition” button in the menu bar 1 shown in FIG. 5, and at the same time, the paper type selection screen 2H and the division method selection screen 2I are displayed in the sub-configuration menu 2. Is displayed.

  First, in order to determine the position of the flexible paper (paper) in the transport path, a message for prompting input of coordinate values at both ends of the paper is displayed in the command field 4. As a method for inputting the coordinate value, a numerical value may be input from the command column 4 or the coordinate position on the graphical screen 3 may be directly designated by a pointing device attached to a computer such as a mouse.

  When the coordinates of the edge are defined, as shown in FIG. 5, a straight line (broken line) 32 connecting the both ends 31 is drawn on the graphical screen 3, and how the paper is placed in the transport path. I can confirm.

  Next, a message for prompting the input of the division number n when discretizing the flexible paper represented by the straight line (dashed line) 32 into a plurality of spring-mass systems is displayed in the command column 4, and the command is accordingly displayed. In the column 4, the division number n is entered.

  As for the number of divisions, the larger the value of n, the more reliable the analysis result. However, since it takes much time, as a rough guideline, n (positive number) = (paper length) / (1 mm ) Seems to be optimal. Further, the curl shapes of the leading edge and the trailing edge of the paper are also set here.

  When the selection screen for the front end or rear end of the sub-configuration menu 2J in FIG. 5 is selected, the graphical screen 3 is switched to FIG. 6, and calculation is performed by inputting the curl height and the distance from the end to the start of the curl curvature. Create a paper shape first at the start. Also, as shown in FIG. 6, a plurality of curl settings can be performed.

  At the same time, representative paper type names are registered in advance in the paper type selection screen 2H, and the type of paper that is the current calculation target is selected by clicking. Here, the calculation parameters necessary for calculating the motion (behavior) of the paper in the transport path are information on the Young's modulus, density, and thickness of the paper, and each paper type displayed on the paper type selection screen 2H. These parameters are assigned as a database.

  In the example of FIG. 5, EN100DK, which is a representative recycled paper, is selected as the paper type. By this operation, the Young's modulus of EN100DK is 5409 MpA, the density is 6.8 × 10 −7 kG / mm 3, and the paper thickness is 0.0951 mm. Is selected from the database.

  When discretization into spring-mass elements by the paper model creation process (step S103) is completed, the process proceeds to the transport condition setting process of step S104 (transport condition setting means). Here, the driving conditions of the conveying roller, the control of the flapper for branching the conveying path, and the friction coefficient at the time of contact between the conveying guide and the conveying roller and the paper are defined.

  When the “transport condition” button in the menu bar 1 is pressed, the transport condition setting process is performed. At this time, as shown in FIG. 7, a screen for defining the drive condition and the friction coefficient in the sub-configuration menu 2 Appears.

  When “coefficient of friction” is selected from the driving conditions listed in the sub-configuration menu 2, the roller or guide displayed on the graphical screen 3 is individually selected, and the coefficient of friction μ with the paper is shown in FIG. Input depending on the speed difference between the transport roller and the paper as shown. This defines the coefficient of friction.

  When the paper comes into contact with the guide and the vertical drag obtained by the contact calculation is N, the frictional force μN is set to work in the direction opposite to the paper transport direction as shown in FIG. Further, when the paper comes into contact with the non-nip area of the transport roller, a speed difference ΔV between the transport roller speed Vr and the transport speed Vp of the paper in the roller collecting direction is obtained, and friction is determined from the relationship shown in FIG. The coefficient μ is determined, and the frictional force μN is set so as to work.

  Therefore, as shown in FIG. 10, the frictional force μN acting between the transport roller and the paper is a positive value of the friction coefficient μ according to FIG. 8 when the peripheral speed Vr of the transport roller is faster than the paper speed Vp. Therefore, it works in the direction of accelerating the paper in the transport direction. On the other hand, when the peripheral speed Vr of the transport roller is slower than the paper speed Vp, the friction coefficient μ is a negative value, so that the friction force μN acts in a direction opposite to the transport direction of the paper.

  Next, as for driving condition input, FIG. 11 shows an example of input of roller driving conditions in the present embodiment. At the stage when the driving condition “roller” in the sub-configuration menu 2 is selected, a roller for which a driving condition is to be defined is selected from among the conveying rollers displayed on the graphical screen 3.

  When the selection of the conveying rollers is completed, the screen shown in FIG. 12 is displayed, which one of the roller pairs is designated as the driving side, and the roller pair in a state where the roller is pressed by a spring or the like. The inter-axis distance 141 is input.

  Accordingly, as shown in FIG. 13, the roller pair changes the center position of the driven roller to the position of the inputted inter-axis distance 141 with reference to the driving roller. At the same time, in the system internal processing, based on the overlapped roller pair shape, a perfect circle indicating the roller pair is divided into a contact area (nip area) 151 and a non-nip area roller surface 152.

  Next, as shown in FIG. 14, a graph showing the roller conveyance speed Vr with respect to time is displayed on the graphical screen 3. When a feature point consisting of a set of time and transport speed Vr is input from the command column 4 as needed, a graph is created on the graphical screen 3.

  In FIG. 14, the conveyance speed is linearly increased from 0 to 100 mm / second by 0 to 1 second, and is maintained at 100 mm / second from 1 to 3 seconds, and from 100 to 0 mm / second from 3 to 4 seconds. Shows an example of deceleration.

  When the conveyance condition setting process (step S104) is completed, the process proceeds to the jam condition setting process in step S105 (jam condition setting means). Here, first, as shown in FIG. 15, a section for performing jam determination is set. By pressing the “define jam” button from the menu bar 1, “section setting” and “time setting” are displayed in the sub-configuration menu 2.

  Therefore, the start of “section setting” is selected, and a straight line is drawn on the graphical screen 3 so as to cross the paper transport path. The end selection is similarly drawn with a straight line. When the paper behavior analysis is actually performed, the time from the time when the paper crosses the start straight line to the time when the paper crosses the end straight line is determined as a jam determination target.

  Therefore, as shown in FIG. 16, the minimum value and the maximum value of the time during which the paper passes through the section are set, that is, the jam time is set. For example, when the minimum value is 0.1 seconds and the maximum value is 0.25 seconds, when the paper passes through the section set by the result of the behavior analysis in 0 to 0.1 seconds or less, 0.25 If it takes more than 2 seconds, it is judged as jam.

  As described above, when each conveyance condition (driving condition and friction coefficient) is set in step S104, the paper conveyance state is calculated in the motion calculation process in step S106 (conveyance state calculation means).

  According to the present embodiment, when the paper has been conveyed to the vicinity of the roller pair, first, contact determination is performed on the mass point group obtained by discretizing the paper and the surface of the non-nip region roller. When contact is made, a frictional force corresponding to a speed difference ΔV between the roller transport speed Vr and the paper transport speed Vp is applied to the paper quality point. Then, when the paper quality point moves on the surface of the non-nip region roller and enters the nip region, a boundary condition is imposed in which the paper quality point is forcibly moved by the roller conveyance speed Vr.

  Note that the motion calculation process in step S106 is repeatedly executed after the element subdivision process is performed on the paper in step S107. This subdivision process is the same as the process in the conventional paper conveyance simulation. The description is omitted here.

  Next, as a result of performing analysis calculation in a plurality of curl states with one model, if it is not determined as a jam based on the set jam definition (step S108), the single item or unit for which the movement definition has been performed is defined as X The direction is shifted by 0.2 mm (step S109). Then, the motion calculation process is performed again. Here, step S108 constitutes a jam occurrence determination means, and step S109 constitutes a first movement means.

  The movement in the X direction is repeated until a jam occurs. When the jam occurs, the single item or unit for which the movement is defined is returned to the original position and is shifted by 0.2 mm in the Y direction (step S111). The motion calculation process is performed again.

  Similarly, as a result of performing analysis calculation in a plurality of curl states with one model, if it is not determined as a jam based on the set jam definition (step S108), the single item or unit for which the movement definition is performed is again defined as defined. The direction is shifted by 0.2 mm (step S109). Then, the motion calculation process is performed again.

  Further, the movement in the X direction is repeated until the jam occurs, and when the jam occurs, the single item or the unit for which the movement definition is performed is returned to the original position and is shifted by 0.2 mm in the Y direction (step S111). The motion calculation process is performed again from the position. Here, step S111 constitutes a second moving means.

  This operation is performed until jamming is observed when the amount of deviation in the X direction is 0 mm and the amount of deviation in the Y direction is 0.2 × N (times) mm (region in the first quadrant of FIG. 17). Next, the X direction is also returned to the original position in the Y direction, and is similarly shifted by -0.2 mm in the X direction until the occurrence of a jam is detected. The deviation amount in the X direction is 0 mm, the deviation in the Y direction. This is repeated until a jam is seen at an amount of 0.2 × N (times) mm (second quadrant region in FIG. 17).

  Further, the X direction is also returned to the original position in the Y direction, and is similarly shifted by -0.2 mm in the X direction until jamming is seen, and this time by -0.2 mm in the Y direction. This is performed until a jam is observed when the amount of deviation in the X direction is 0 mm and the amount of deviation in the Y direction is −0.2 × N (times) mm (region in the third quadrant of FIG. 17).

  Finally, the X direction is also returned to the original position in the Y direction, and is shifted by 0.2 mm in the X direction until a jam occurs again, and is shifted by -0.2 mm in the Y direction again. This is performed until a jam is observed when the amount of deviation in the X direction is 0 mm and the amount of deviation in the Y direction is −0.2 × N (times) mm (region in the fourth quadrant of FIG. 17). Then, the analysis process ends when the determination is made that all the areas are covered (step S110). Here, step S110 constitutes a boundary region specification determination unit.

  The paper simulation result obtained by the above processing is displayed in step S112 (display means). This result display process is performed by pressing a “result display” button in the menu bar 1. As shown in FIG. 18, when the area display of the sub-configuration menu 2 is performed, a so-called permissible range (hatched area in FIG. 18) where a jam occurs when a single guide or unit is relatively displaced is shown.

  For example, in this result, if the center position of the design is too close to the boundary of the allowable range or the allowable range is too small, it becomes a guideline such as changing the guide shape. In addition, as shown in FIGS. 19 and 20, a moving image menu and a plot menu are displayed in the sub-configuration menu 2.

  The moving image menu shown in FIG. 19 has a play button, a stop button, a pause, a fast forward button, and a rewind button, and each of the analyzed cases can be visualized as a moving image on the graphical screen 3 using these buttons. FIG. 19 shows the paper behavior when the curl shape is [1] (A, B) = (0, 0), the movement amount in the X direction is 0.6 mm, and the movement amount in the Y direction is also 0.6 mm. FIG.

  Furthermore, FIG. 20 shows a plot screen in the present embodiment. In order to perform the behavior of the paper more quantitatively, each analysis result with respect to time such as the conveyance load of the guide and the conveyance roller, the acceleration, speed, and displacement of the paper is displayed in a graph. FIG. 20 also shows the paper behavior when the curl shape is [1] (A, B) = (0, 0), the movement amount in the X direction is 0.6 mm, and the movement amount in the Y direction is also 0.6 mm. It is a graph which shows the resistance of a certain guide.

  As described above, in the present embodiment, the permissible range with respect to the relative positional deviation of the single-piece guide or unit and the individual analysis result display are performed, thereby making it possible to evaluate various conveyance paths.

  Up to now, among several parameters, each individual case can be completely analyzed individually, or all cases within the range set by the analyst can be analyzed regardless of whether or not a jam has occurred. There was a design support device to perform.

  However, as described above, according to the present embodiment, it is more efficient than the conventional one by omitting the analysis calculation of the setting in which the jam has already occurred and displaying the setting in which the jam does not occur in the area. Simulation is possible.

  In addition, by displaying individual analysis results, it is possible to evaluate each of the transport paths in a wider range and in detail.
