  • Page 5: General Information

    1 General information Press-Right is a monitor and measuring device that is connected to a press and monitors the quality of productive processes. Being interfaced with a displacement transducer and a load cell, it continuously monitors its positions and instantaneous force.
  • Page 6 Right may set both the absolute and the relative positions. In order to measure the contact point on the manufactured piece, Press-Right use the force transducer: when the force measured exceeds the planned value, the relative zero point is set. This zero point is called conctact START FORCE position.
  • Page 7 The piece is good only if the analysis of the minimum/maximum limits and the tolerance range have a positive result. Press-Right also monitors the cylinder return at the end of the production process. Such return may result from the exertion of a specific force (stop force) or at a specific position (final position).

During PRE-STOP POSITION the pre-stop stroke, the cylinder regulates the speed according to the force value measured. Now, before continuing, make sure that there is At least a 50mm free space in the stroke of the cylinder.

  • Page 13: The Job

    4 The JOB Press-Right stores all settings (parameters, range and counters) referring to the Job. There may be at least 100 of them, each of which with its own name. The main menu also includes the item. By means of this sub-menu, it is possible JOBS MANAGEMENT to create a new job, select one among those present, change the current job or delete it.

    It is possible to create additional jobs by using the unlock password. It is possible to select a job other than the one automatically selected by using the unlock password. The graph In the menu, the item is available, allowing for the editing of the graph axes. EDIT JOB SET GRAPH Note that it is not possible to edit these values and fully or partly hide the range.

  • Page 16: Scraps Options And Management

    As shown in both figures, it is possible to select the following values: GRAPH ORIGIN It is the origin value of the horizontal axis of the heights; this parameter allows to hide the undesired part of the stroke, such as the approach stroke. If the relative heights are used, the origin is usually set to zero.

  • Page 17: Channel Management

    For every job the self-verification function can be excluded. It is managed by Press-Right as follows: Whenever the device is switched on or the self-verification is managed by Press-Right as follows: Whenever the device is switched on or every N1 pieces, N2 sample pieces must be processed.
  • Page 18 4.14.1 Additional monitoring options The monitoring options are as follows: DO NOT RUN THE ADDITIONAL MONITORING SESSION The additional monitoring session is not performed. MEASURE AT START The additional monitoring is carried out when the device receives a STARTcommand. MEASURE AT SHUTDOWN The additional monitoring is carried out when the device commands the shutdown and the piece is good.

  • Page 20: Check Points

    5.2.1 How to choose the limits The initial height limits allow to monitor the dimensions of the components before they are processed. They may be useful to monitor the dimensions of the pieces to assemble or to monitor whether all components necessary for the processing are present. The selection mode of the limits which monitors the maximum force and height reached, also in this case, by the type of production.
  • Page 21 EXCLUDE PRESS SELF-VERIFICATION It disables the self-verification of the press during job execution. EXLUDE TEST SELF-VERIFICATION 1 It disables the self-verification of the additional test during job execution. SAVE GOOD PIECE CURVE It saves the good piece curves on the SD memory card. SAVE SCRAP PIECE CURVE It saves the scrap piece curves on the SD memory card.

  • Page 22: The Tolerance Range

    6 The tolerance range The tolerance range is used to monitor the curve and, as a result, it monitors the quality of the piece. The range consists of two lines called upper edge and lower edge. In order to classify the piece as good, the motion-force points representing the curve must not appear above the upper edge or below the lower edge.
  • Page 23 SET THE GRAPH It allows to change the graph axes. EXIT It ends the range change. To ends the range change, it is possible also to use the key. Figure 13 Figure 14...

  • Page 24: Delete The Range

    The range may be changed by moving the dots at the end of each edge. When the range is changed, only one of the dots of the edges is highlighted; this dot is the active dot, that is, the one that may be moved.

  • Page 25: Scrap Piece

    If the job includes multiple stages, the Press-Right may require confirmation for the scrap materials. If the range is not reached by the curve and there is no minimum height limit, the scrap is reported...

  • Page 26: Scrap Management

    For instance, it is possible to sort reusable scraps from not recyclable materials. When a special scrap is detected, Press-Right activates the second scrap port ad count the piece separately. This way, it is possible to know whether the pieces are rejected by mistake by the operator.

  • Page 27: Measured Values

    8 Measured values Press-Right stores the motion-force curve and it measures the some parameters which may be monitored thanks to the limits. The curve stored can be analyzed with the analysis cursor (chapter 8.2). The vales measured may be visualized at the end of each process (chapter 8.1) and may be measured by an external controller by means of a serial code.

  • Page 28: Analysis Cursor

    MIN-MAX CHECK POINT These are the minimum and the maximum values measured within the whole check point reported. CHECK POINT VARIATION It is the force variation measured at a specific check point. CHECK POINT FORCE It is the force value measured at a specific check point. CHECK POINT HEIGHT It is the height value measured at a specific check point.
