Definitions

  • Handheld pressing devices are commonly used for the purpose of joining pipes.
  • a press fitting is slipped on the pipe ends and is then compressed by means of the pressing device, wherein both the press fittings and the pipe end are compressed.
  • the pressing devices include a pressing tool with two or more pressing jaws that approach each other during the pressing operation, whereby the press fitting is pressed together with the pipe end.
  • Such pressing devices are used for great numbers of pressing operations in buildings, in particular when erecting a building.
  • different pipe pressing applications demand differently equipped pressing tools, jaws and fitting or connectors, which means that almost every component has to be specially adapted to an individual specification.
  • This means that each press tool has to be specially designed with a specific setup of accessories, such as jaws providing desired operational features, with the result that the manufacturing costs for the pressing tools tend to be rather high.
  • the scanner is configured to scan coding means, such as NFC tags, RFID tags, bar codes, data matrix codes or any combination thereof on the pressing jaws and/or on the work pieces, in particular the press fitting and the pipe, in order to identify the pressing jaws and/or the work pieces.
  • the data collecting element is capable of reading out so-called "distinguishing marks", which may be part of the pipe pressing device or its components, in particular the pressing jaw. These distinguishing marks can also be present at work pieces to be joint by the pipe pressing device. Suitable distinguishing marks are colour marks and/or special characters.
  • barcodes or QR codes can be used, which allow for a simple identification of the pressing jaw and work pieces used.
  • the adapter comprises an input unit, being configured to receive the data of the pressing tool, wherein the data can be manually entered by a user.
  • the input unit may include an internal display device and/or an internal memory device to display the data of pressing tool pre-stored in the adapter in advanced. Storing data of pressing tool in advances allows the user select manually via the display device.
  • the present invention further provides a method for documenting pressing operations performed on two work pieces, in particular a pipe and a press fitting, performed with a handheld pressing device with a pressing tool having a plurality of pressing jaws; the method comprises:
  • data of the pressing devices collected in the step 2) includes the data of the pressing jaw used and/or the work pieces used by scanning coding means, such as NFC tags, RFID tags, bar codes, data matrix codes or any combination thereof on the pressing jaws and/or on the work pieces, in particular the press fitting and the pipe.
  • scanning coding means such as NFC tags, RFID tags, bar codes, data matrix codes or any combination thereof on the pressing jaws and/or on the work pieces, in particular the press fitting and the pipe.
  • the data collected in the step 2) further includes of the data of press tool used by a user manually selecting from the data of pressing tools pre-stored in the memory unit in advance.
  • the data is selected from a group comprising type, name, serial number, last service, or any combination of aforementioned information of the pressing tool and/or pressing jaw, type, name and/or batch of the work pieces.
  • the data collected in step 3) is selected from a group comprising the pressing tool pressure, force, motor loads, current consumption values, strain values or any combination thereof.
  • the data is collected by a sensor system inbuilt in the pressing tool. Hence, it can be proven subsequently that the required pressing force has been reached and the pressing operation has been executed basically completely by reading out the data at a later time.
  • the data collected in step 3) further includes the success or fail information from the pressing tool, an operation number and - if the pressing operation was not successful - the reason for failure.
  • the success or fail information from the pressing tool it is necessary to ensure the proper functionality of the pressing device.
  • the user of the pressing device may - as a consequence - be able to read out the information whether the pressing device functions properly.
  • the present handheld pressing device 10 is used for joining two work pieces, in particular a pipe 18 and a press fitting 19, by pressing.
  • the pipe pressing device 10 comprises a pressing tool 11 with a plurality of pressing jaws 12.
  • the pressing tool 11 includes a converting unit and an electric motor (not shown), the electric motor and the converting means being enclosed by a housing.
  • a battery pack 14 is detachably mounted on the pressing tool to supply power to the electric motor.
  • the pressing tool 11 has a coupling portion 15 that is attached to the battery pack 14 on the rear end of its housing while the battery pack 14 has a coupling portion 16 of the battery pack 14 that is to be attached to the pipe pressing tool 11 on the top side of the battery pack 14.
  • the pressing jaws 12 of the pressing tool 11 are pressed apart at the rear part, i.e. on the side facing the converting unit. Thereby, the pressing jaws 12 are pivoted about pivot pins so that the pressing jaws 12 approach each other at the front part, i.e. on the side averted from the converting unit. Thereby, a compression is achieved. Due to the pressing movement of the pressing tool 11, a press fitting 19 is joined with a pipe end 18 by pressing and is thus joined with the same in a reliable and tight manner. A sensor system 13 is arranged on the head of the pressing tool 11 close to the pivot pin of the pressing jaw 12 coupled to the pressing tool 11
  • an adapter 20 for a pipe pressing device 10 for joining two work pieces comprises a main body 23 that includes a first coupling portion 21 and a second coupling portion 22.
  • the first coupling portion 21 has a configuration basically identical to a coupling portion 16 of the battery pack 14 that is to be attached to the pressing tool 11.
  • the second coupling portion 22 has a configuration basically identical to a coupling portion 15 of the pipe pressing tool 11 that is attached to the battery pack 14.
  • the adapter 20 can be mechanically and/or electrically connected to the housing of the pressing tool 11 by attaching the first coupling portion 21 to the coupling portion 15 of the pressing tool 11.
  • the adapter 20 can be mechanically and/or electrically connected to the battery pack 14 by attaching the second coupling portion 22 to the coupling portion 16 of the battery pack 14.
  • the adapter can be attached to the pipe pressing tool 11, no change in the designs of either the battery pack 14 or the pressing tool 11 is necessary, and thus no additional costs are incurred. Also, the external adapter 20 is adapted to work with various pressing tools on a same platform, which means the interfaces between these pressing tools and battery pack 14 are same.
  • the pressing jaws 12 is equipped with a barcode element and the press fitting 19 is equipped with an NFC element and the pipe 18 is equipped with a RFID tag element.
  • the scanner 25 captures three elements and can thereby identify the pressing jaw12, the pipe 18 and the press fitting 19.
  • the adapter 20 may comprise an input unit 26.
  • the input unit 26 may in particular be an internal display device being configured to receive the data of the pressing tool 11 manually input by a user.
  • the internal display device display the data of pressing tool pre-stored in the memory unit 24 of the adapter 20. Pre-storing data of the pressing tool 11 in advance allows the user to select manually via the display device at a later time.
  • a sensor system 13 inbuilt in the pressing tool 11 is used to measure the data of the pressing operation.
  • the data of the pressing operation may in particular be the tool pressure, force, motor loads, current consumption values, strain values, the operation number or any combination thereof over the full press cycle.
  • a controller 28 of the adapter 20 will assess if the measured data from the sensor system 13 match the pre-stored data in the memory unit 24. In particular, the controller 28 compares the measured data collected by the sensor system 13 to the pre-stored data. If the measured data match with the pre-stored data, the pressing operation will be regarded as successful. However, if the measured data have a deviation from with the pre-stored data, the pressing operation will be regarded as having failed.
  • the adapter 20 comprises transmitter unit 27 adapted to be connected to an external device 29 to transmit the collected data to the external device 29.
  • the information result from the collected data transmitted from the adapter 20 by the transmitter unit 27 via Bluetooth.
  • An overview of the collected data of the pressing operations stored in the memory unit 24 is reached via the external device 29. Hence, for each single pressing operation, the data can be well documented and/or read out at any time.
  • the present invention further provides a method for documenting pressing operations performed on two work pieces.
  • the method for the documentation of pressing operations for later use as evidence.
  • the adapter 20 is connected to both the pressing tool 11 and battery pack 14 mechanically and electrically. Specifically, it is possible that the data collecting is started automatically with each single pressing operation or, as an alternative, upon activation of the pressing device so as to collect the respective pressing operations.
  • the data of the pressing tool 11 is selected manually by the user from the input unit 26.
  • the data are type, name, serial number, last service, or any combination of aforementioned information of the pressing tool 11.
  • the scanner 25 collects data specific to the pressing devices before pressing operation.
  • the scanner 25 will scan the coding means 17, like NFC tags, RFID tags, bar codes, data matrix codes or any combination thereof, which can be attached to the pressing jaws 12 and/or on the work pieces, in particular the press fitting 19 and the pipe 18.
  • Data of the pressing devices collected by the adapter 20 here includes the information of the pressing jaw 12 used, such as type, name, serial number, last service, and the information of the fittings 18 and pipe 19, such as type, name, batch, or any of combination.
  • the collected data is transmitted in particular in a wireless manner, for example via WLAN, Bluetooth, IR transmission or radio transmission to an external device 29.
