Definitions

  • pressing is performed using a (press) fitting.
  • Pressing machines such as pipe pressing machines, can be used to connect a pipe to a press fitting.
  • a fitting can, for example, be designed as a pipe fitting, which can be used as a connecting piece in a pipeline.
  • a fitting can be made of various materials, such as copper, aluminum, plastic, composite, and/or (stainless) steel.
  • the present invention is therefore based on the object of achieving the most optimal and material-friendly pressing of a fitting onto a pipe.
  • an improved (pipe) pressing machine is to be provided that enables such pressing.
  • the press machine also includes a Press jaw holder for coupling a press jaw assembly to the pressing machine.
  • the press jaw holder couples to the press jaw assembly in such a way that the pressing machine can drive press jaws of the press jaw assembly.
  • the coupling is achieved via at least one coupling pin.
  • the press jaws of the press jaw assembly can be configured to be movable relative to one another and, for example, can be closed and also moved apart so that, when moved apart, a tubular workpiece, such as a fitting, can be arranged between the press jaws.
  • the press jaws of the press jaw assembly can be interchangeable. Different press jaw assemblies and/or press jaws can be designed for different tasks, such as pressing, crimping, or cutting.
  • a press jaw assembly comprises at least two press jaws.
  • the drive can be connected to the press jaw assembly directly or via a gear to transmit the drive force to the press jaw assembly and the press packs.
  • the force acting on the press jaws or the press jaw assembly can be variably adjusted, for example, by varying motor parameters or other parameters (such as gear settings).
  • the pressing machine further comprises a sensor system configured to identify a pressing jaw arrangement and to provide corresponding sensor data.
  • the sensor system can be configured to recognize an individual pressing jaw arrangement or to recognize a pressing jaw arrangement by its type.
  • the sensor system can comprise detection means (e.g., a sensor) as an interface to the pressing jaw arrangement, and corresponding evaluation means, which can comprise a processor and/or memory with corresponding program code.
  • the detection means can be provided separately from the evaluation means on the pressing machine.
  • the sensor system can be powered by a power source arranged on the pressing machine, which can also power the drive or electric motor, for example.
  • the sensor system can also be activated by a user/operator using a button to carry out the identification. This allows for targeted control of how and when the identification should take place.
  • the sensor system can be configured to detect an exchange and in particular the coupling of a pressing jaw arrangement with the pressing jaw holder and to carry out the identification after detecting the exchange or the coupling.
  • Identification does not necessarily mean that a single jaw assembly is identified as an individual jaw assembly. Rather, it is sufficient that a jaw assembly is identified or recognized as different from another jaw assembly. For example, during identification, the jaw assembly can be classified based on its model number. In one example, it can be recognized that a jaw assembly for pressing stainless steel fittings with a diameter of 15 mm is present and/or coupled. Resulting sensor data can characterize the identified jaw assembly.
  • the press machine comprises a controller which is configured to control the drive based on the sensor data.
  • the drive is controlled accordingly.
  • the press jaw arrangement can be driven differently by the drive to ultimately optimally deform the workpiece.
  • the present invention thus allows the forming process to be carried out depending on the coupled press jaw arrangement.
  • This allows an individual pressing force to be applied by the drive, depending on the type of press jaw arrangement used, in order to achieve optimal and material-friendly deformation of the workpiece.
  • the use of the sensor system allows the press jaw arrangement to be automatically identified and the corresponding data to be transmitted to the drive, so that the user or operator of the press machine does not have to make any inputs themselves and is therefore not subjected to additional stress. This can reduce the risk of incorrect operation.
  • the pressing machine comprises a storage medium with a database.
  • the database preferably includes, for a plurality of press jaw arrangements, specific control parameters for controlling the press machine. Furthermore, the controller can then control the drive according to the at least one specific control parameter. According to the identification of the press jaw arrangement, corresponding control parameters can thus be loaded from the memory or from the database and used to operate the drive. For example, control parameters for a pressing jaw arrangement for stainless steel fittings and different control parameters for a pressing jaw arrangement for copper fittings can be stored in the database. Depending on whether a pressing jaw arrangement for stainless steel or copper fittings was identified by the sensor system, the corresponding control parameters can be loaded from the database and used by the controller to control the pressing machine and ultimately the drive. Corresponding control parameters can be stored in the database for different characteristics of the pressing jaw arrangements (e.g.
  • the database can be accessed via a (wired or wireless) interface, for example to update the contents of the database.
  • control parameters preferably comprise pressing parameters, which preferably include a maximum pressing force, a pressing speed, a pressing path, and/or a pressing time.
  • pressing parameters preferably include a maximum pressing force, a pressing speed, a pressing path, and/or a pressing time.
  • certain pressing forces, pressing speeds, pressing paths, and/or pressing times can thus be specified, for example, which the pressing machine is to use to press or deform the fitting with the pipe section.
  • These parameters can, for example, be specified in the form of a pressing curve that specifies a temporal progression of the pressing force, pressing path, and/or pressing speed.
  • control parameters can, in particular, include drive parameters, which in particular include a drive speed, drive power, and/or oil pressure.
  • drive parameters which in particular include a drive speed, drive power, and/or oil pressure.
  • various drive parameters can thus be stored in the database, which can be loaded based on the identified pressing jaw arrangement in order to ultimately deform the workpiece.
  • the person skilled in the art will understand that the pressing parameters or drive parameters may include motor and/or gear parameters that can control the power transmission from the drive to the pressing jaws.
  • the sensor system can comprise at least one optical sensor, a contact-based sensor, an inductive sensor, and/or a capacitive sensor, wherein the sensor system can be configured, in particular, to read an RFID and/or NFC transponder.
  • the sensor system can alternatively or additionally be configured to read a barcode or a QR code.
  • the sensor system can comprise a Bluetooth module configured to read a corresponding Bluetooth module.
  • a contact-based sensor may include an electrical contact that contacts a corresponding electrical contact of the die/die assembly to identify the die/die assembly.
  • the use of an inductive and/or capacitive sensor enables reliable identification, as inductive and/or capacitive sensors are less susceptible to contamination than, for example, optical or contact-based sensors.
  • the RFID and/or NFC transponder or the corresponding Bluetooth module can have an identifier that is read during identification. This identifier is characteristic of the type of press jaw arrangement or of an individual press jaw arrangement and can, for example, include a serial number and/or a type number. Based on the read identifier and the database, the control parameters can then be determined. Likewise, the RFID and/or NFC transponder or the corresponding Bluetooth module can contain the control parameters themselves. These can then be read during identification and passed on to the control system. This means that the press machine database does not necessarily have to be updated if new or additional press jaw assemblies are to be used.
  • the pressing jaw assembly carries the required control parameters in the RFID and/or NFC transponder assigned to it or in a corresponding Bluetooth module.
  • RFID radio frequency identification
  • the press jaw assembly can be identified automatically and contactlessly using RFID technology.
  • An RFID reader (sensor) mounted on the press machine can read the identification and/or control parameters, which can be provided by a corresponding RFID transponder of the press jaw assembly.
  • An RFID transponder can be read without the need for additional power.
  • the press jaw assembly can be designed passively and requires no additional interface or source for providing electrical power.
  • NFC technology or near-field communication
  • RFID technology for the contactless exchange of data via electromagnetic induction or capacitive transmission.
  • the communication between the corresponding NFC participants can be active-passive or active-active.
  • the active part i.e., the part supplied with electrical energy
  • the passive part is located on the press jaw assembly.
  • the press jaw assembly can be designed passively and does not require an additional interface or source for providing electrical energy.
  • Bluetooth communication enables data transmission between devices over short distances using wireless technology. Communication takes place using a correspondingly developed industry standard, such as the IEEE 802.15.1 standard.
  • a first reading range of the sensor system can be limited and amount to a maximum of 0.3 m, preferably a maximum of 0.2 m, and most preferably a maximum of 0.1 m.
  • the first reading range of the sensor system can be selected such that only one coupled pressing jaw arrangement can be identified. Limiting the first reading range prevents the incorrect pressing jaw arrangement located near the pressing machine from being accidentally identified.
  • the pressing machine is provided together with a plurality of pressing jaw assemblies in a transport case or on a workbench. When the pressing machine is put into operation, only the coupled pressing jaw arrangement or the one to be coupled should be identified. This can be ensured by limiting the first reading range.
  • the sensor system can be configured to identify a workpiece, wherein the storage medium comprises a database which comprises at least one specific control parameter for a plurality of workpieces, wherein the controller is configured to control the drive according to the at least one specific control parameter.
  • the drive is therefore controlled accordingly depending on the identified workpiece.
  • the pressing jaws can, for example, be driven differently by the drive in order to ultimately deform the workpiece optimally.
  • Both the type of workpiece and the type of pressing jaw arrangement can be taken into account when selecting the control parameters. In particular, it can be checked whether the identified pressing jaw arrangement matches the workpiece to be pressed. If this is not the case, an alarm can be issued to prevent incorrect pressing and/or damage to the pressing machine.
  • the control parameters can also be adapted to the identified workpiece and thus over-pressing can be avoided.
  • the pressing force applied would be too high if the type of pressing jaw arrangement were taken into account alone. If, however, the type of workpiece is also recognized, the pressing force can be reduced accordingly and the workpiece can be pressed with the supposedly unsuitable pressing jaw arrangement - but with reduced pressing force.
  • the present invention thus allows the forming process to be carried out depending on the object to be formed and the press jaw arrangement used. This allows an individual pressing force to be applied by the drive depending on the type of workpiece used or the coupled press jaw arrangement, in order to achieve optimal and material-friendly forming without damaging the workpiece or the press machine.
  • a second reading range for identifying the workpiece can preferably be in the range from 0 meters to 5 meters, more preferably in the range from 0.01 meters to 2 meters, more preferably in the range from 0.02 meters to 1 meter and more preferably in the range from 0.05 meters to 0.5 meters.
  • the sensor system can therefore only identify workpieces that are located within the second reading range. This ensures that only those workpieces that are actually intended to be deformed are identified. This at least partially prevents accidental identification of workpieces that are far away and not to be deformed.
  • the first and second reading ranges can be different.
  • the sensor system is configured to detect characteristic features of the workpiece, in particular characteristic geometric features of the pressing jaw arrangement and/or a workpiece.
  • the sensor system can detect a shape and/or size of at least part of the pressing jaw arrangement and/or the workpiece. Based on these characteristic features, the pressing jaw arrangement and/or the workpiece can be identified, at least according to its type, and the drive can then be controlled accordingly to optimally deform the workpiece.
  • the sensor system comprises a sensor such as a camera, an optical scanner, an RFID reader, an NFC reader, and/or a Bluetooth module for identifying the workpiece.
  • the same sensor or different sensors or sensor types can be used to identify the workpiece and the press jaw assembly.
  • the camera can be an optical camera, which can have sufficient resolution and quality to identify the workpiece at least by its type. For example, a fitting with a diameter of 15 mm can be identified using the camera. Furthermore, the material of the workpiece can be deduced from color values.
  • the optical scanner, the RFID reader, the NFC reader, and/or the Bluetooth module can detect data or identifiers that can be provided, for example, by the workpiece itself or the press jaw arrangement, and allow the workpiece to be identified. For example, the optical scanner can detect a barcode or QR code arranged on the workpiece.
  • a light source can also be provided on the press machine, which can at least partially illuminate or illuminate the area captured by the camera or scanner.
  • the sensor system is configured to detect a barcode on the workpiece, a QR code on the workpiece, an identifier in an RFID transponder on the workpiece, an identifier in an NFC transponder on the workpiece, and/or an identifier in a Bluetooth module on the workpiece.
  • the workpiece can be equipped with corresponding codes, transponders, or modules to provide the press machine with corresponding data for identifying the workpiece—at least by its type.
  • the sensor of the sensor system is arranged directly on the press jaw holder.
  • the sensor is at least partially covered by an element of the press machine in a first configuration of the press machine, and is uncovered by the element in a second configuration of the press machine.
  • a sensor of the sensor system can be covered by a part of the housing of the press machine, which can protect the sensor from contamination or other environmental influences.
  • the press jaws are moved towards each other or brought into the first configuration, whereby the sensor can again be at least partially covered by a part of the housing. This also ensures that identification using the sensor system only takes place when the workpiece is to be deformed. This prevents inadvertent misidentification of a workpiece that is nearby (e.g., lying on a workbench).
  • the pressing jaws of the pressing jaw arrangement are free of the sensor system.
  • no elements of the sensor system are arranged on the pressing jaws or the pressing jaw arrangement.
  • the sensor system can thus, for example, be arranged exclusively on or in a hand part of the pressing machine. This enables easy exchange of the pressing jaws or the pressing jaw arrangement.
  • the sensor system is arranged at least partially on the pressing jaws or the pressing jaw arrangement, in particular in a recess in the pressing jaws (for example, to protect the sensor system).
  • the sensor system can be connected to the motor of the pressing machine via a coupling interface.
  • the sensor system is preferably arranged at least partially within a housing of the press machine. If the sensor system is configured to read an RFID and/or NFC transponder, or if it comprises a Bluetooth module, the sensor system can be arranged entirely within the housing of the press machine.
  • the housing of the press machine is at least partially permeable to the readout data.
  • the housing material can comprise glass, ceramic, plastics, or composites, which are at least partially permeable to electromagnetic radiation.
  • the housing can also have suitable recesses to enable reading. This arrangement can protect the sensor system from contamination or other environmental influences, as it is at least partially shielded by the housing of the press machine.
  • the pressing jaw arrangement can at least partially cover the sensor of the sensor system when the pressing jaw arrangement is coupled to the pressing jaw receptacle, wherein the sensor is at least partially uncovered when no pressing jaw arrangement is coupled to the pressing jaw receptacle.
  • the sensor system or the sensor can be protected from contamination or other environmental influences.
  • the reading accuracy of the sensor system can be increased because the sensor system or the sensor of the sensor system is arranged directly adjacent to the coupled pressing jaw receptacle and is not covered by other parts, such as a housing part.
  • a very small maximum first reading range can be realized and the risk of incorrect identification of adjacent, uncoupled pressing jaw receptacles can be reduced.
  • the method steps of identifying, gripping and/or controlling can be implemented in a computer program, wherein the computer program can cause a corresponding press machine system to carry out the respective steps.
