  • Page 5: General Informations

    1 General informations Press-Right is a control and measurement instrument which, when connected to a press, guarantees the quality control of the production processes. Interfaced to a position transducer and a load cell, it continuously detects the position and the instantaneous force.

  • Page 6: Absolute And Relative Positions

    The positions referred to the zero of the cylinder are called absolute positions. The positions referred to the contact position on the piece are called relative positions. The Press-Right can use both absolute and relative positions. The load cell is used to detect the contact position: when the force measured by the load cell exceeds CONTACT DETECTION a programmed value, the position values is set to zero.

  • Page 7: Control Of The Position-Force Curve

    In practice, the Press-Right controls the curve through a tolerance range, check points and limits. The tolerance range positioned around the sample curve is such that if the curve obtained from the current machining does not pass within this range, the piece is rejected.

  • Page 8: Installation Press-Right

    2 Installation Press-Right To install the instrument on the machine, consult the specific manual.

  • Page 9: How To Start

    3 How to start This chapter will walk you through the basics of programming and using the Press-Right instrument. To better illustrate the operations, it is advisable to carry out the tests in practice. Figure2 To turn on the instrument there is a button on the back. When it is pressed, after a few seconds, the display lights up and the graph appears: 3.1 Press-Right user interface...

    To create a job: • Touch the menu button • Touch the JOBS LIST item • Touch the CREATE A NEW JOB item • Enter the name that identifies the job (example TEST 1) and press the enter key. Note: in the rest of this manual, when it is indicated, for example, “JOBS LIST > CREATE A NEW JOB”...
  • Page 11 The item RESET COUNTERS is used to reset the counters of processed pieces. When the batch number is managed, this menu will be replaced by the NEW PRODUCTION BATCH menu which allows the batch number to be entered. This number will be stored together with the curve. The PART NUMBER item allows the insertion of the identification number of the piece being processed.

  • Page 12: Jobs

    4 Jobs The Press-Right memorizes all the settings (parameters, tolerance range, limits and counters) relating to the various jobs in an internal memory. Each group of settings is called Job. Each job has its own name. JOBS LIST item is present in the main menu. Through this menu it is possible to choose a job among those present, create a new one, or delete the job in use.

  • Page 13: Selection Of A Job Via Fieldbus

    4.6 Selection of a job via fieldbus It is possible to select the job to be used via the fieldbus in three different ways: via the job name, via the identification code or via an index number. 4.6.1 Selection from fieldbus by name To select a job, first write the code of the desired job in the string buffer at the address 45, then write command 3 in the CONTROL_WORD_OUTPLC.

  • Page 14: Job Counters

    4.11 Job counters Each job has a piece counter. To access the counter options, select the menu EDIT JOB > SCHEDULING. In this menu it is possible to reset the piece counter or choose a maximum number of pieces to block the instrument.
  • Page 15 The phases will be performed automatically in sequence. If you want to carry out a phase individually out of sequence, select the Do not perform the phases in sequence option in the TOOLS > SETUP > JOBS SELECTION menu. In this case it is not possible to change the phase that will be performed from the menu. It is also possible to have a single phase repeat several times by activating the Phase repeat options in the TOOLS >...

  • Page 16: Parameters

    5 Parameters After creating a new job, the first thing to do is to set the job options in the EDIT JOB > PROPERTY AND OPTIONS menu. Once this is done, it is possible to set the operating parameters. Note: In the jobs the parameters set equal to zero will be ignored by the instrument. 5.1 Movement management The movement profile parameters are the following and can be found in the EDIT JOB >...

  • Page 17: Checkpoints

    Contact position limits They control the contact dimension of the working. For a part to be classified as good, the measured contact dimension must be above the minimum contact dimension limit and below the maximum contact dimension limit. Peak Position limits They control the maximum position reached during machining.
  • Page 18 Check force Measure and control the force at a pre-set position. This check point is also useful for having a discrete value at the end of pressing to be displayed or sent via fieldbus. Check position Measure and control the position at a pre-set force. This check point is useful for checking deformation at a pre-set load.

  • Page 19: Job Options

    The piece code can also be set via a barcode scanner. To use this option, it is necessary to activate the Part number management option in TOOLS > SETUP > VISIBLE OPTIONS menu. Contact Alfamatic to find out which barcode readers are compatible with the instrument. Save curves of pieces good Save the curves of the good pieces on the internal flash memory.
  • Page 20 Save curves Activates the saving of the curves in the internal memory of the instrument. Save a good curve every If you only want to save some curves, with this parameter you can set every how many pieces you want the curve to be saved.

  • Page 21: The Tolerance Range

    7 The tolerance range The tolerance rage is used to control the curve and consequently to control the quality of the piece. The tolerance rage consists of two lines called the upper border and the lower border. For the piece to be classified as good the points representing the curve cannot be above the upper edge, and cannot be below the lower edge.

  • Page 22: Remove The Tolerance Range

    7.3 Remove the tolerance range To eliminate the tolerance range use the EDIT JOB > TOLERANCE RANGE > DELETE menu.

  • Page 23: Rejected Pieces

    If the job has multiple phases, the Press-Right can request confirmation for the rejected. If the tolerance band is not reached by the curve and if the minimum quota limit is not present, the piece is signaled as reject due to the minimum quota not being reached.

  • Page 24: Rejected Management

    For example, it is possible to separate recoverable rejected from unrecoverable rejected. When there is a special reject the Press-Right activates the second reject signal and counts the piece separately. In this way it is possible to know, for example, how many pieces are rejects due to operator error.

  • Page 25: Verification

    8.7 Verification With this command it is possible to configure the self-verification of the job. 8.8 Codes of the job In this menu it is possible to indicate the job name, the selection index and which part of the barcode identifies the job code.

  • Page 26: Measured Values

    9 Measured values The Press-Right stores the displacement-force curve and measures some quantities that can be controlled thanks to the limits. The last curve can be analyzed with the analysis cursor. The quantities measured can be displayed at the end of each process.

  • Page 27: The Tools Menu

    This option doesn't work with phases. Light up the working area This option is available if a Press-Right output is configured to control the work area light. Displays the status of the command signals By activating this option, the status of the inputs and outputs is displayed above the graph.
  • Page 28 ENABLE MANUAL MOVEMENT With this command you can use the arrow buttons to move the cylinder. In the manual movement, the first section takes place very slowly, then the speed increases. If the cylinder is under stress the speed will be limited. GO TO POSITION With this command it is possible to move the cylinder to a known position.

  • Page 29: Instrument Configuration

    By activating this option, the Press-Right is blocked and enabled by the supervision system connected via fieldbus. Wait for computer connection By activating this option, the Press-Right does not allow the machining of the pieces if it is not connected to the WinScope program. Count the piece when it senses a force By activating this option, the Press-Right will not increase the piece counter if it has not measured an initial position.

  • Page 30: Job Selection

    If several load cells are connected to the instrument, activating this option will use a different cell for each phase. This option allows you to connect up to four identical presses working in sequence one after the other to a single Press-Right. 11.2 Job selection These options modify the method used by the instrument to automatically select jobs and phases.

  • Page 31: Diagnosis

    (outside the menus). 12.1 Firmware version The Press-Right has several microprocessors inside. To find out the version of the software contained in the microprocessors, it is possible to view the diagnosis window TOOLS > DIAGNOSIS.

  • Page 32: Special Configurations

    13 Special configurations The Press-Right tool is very versatile. Thanks to Alfamatic's years of experience in pressing, the instrument is set up to solve the most varied customer needs. In order not to unnecessarily complicate the use of the instrument, these functions are hidden and must be made visible manually in the instrument configuration.

  • Page 33: Management Of Supplementary Controls

    In practice, the outcome of the machining can be conditioned by the logic status of three inputs. This logical state can be checked at various times during the working. For additional control number 1, the Press-Right can also activate an output before carrying out the control and, after a pre-set time, read the state of the input.
  • Page 34 13.4.4 Automatic selection of work with tool To automatically select the job according to the tool mounted on the press, activate the relative option in the TOOLS > SETUP > JOB SELECTION menu.

  • Page 35: Data Storage

    14 Data storage The Press-Right is able to memorize the production data in the internal memory. In practice, for each piece produced, a file is created which contains the following information: • The recorded force-displacement curve. • The job settings used when recording the curve.
