Definitions
- Manufacturing device in particular press brake, with electronic tool detection
- the invention relates to a ceremoniesseimichtung, in particular a press brake, for forming workpieces made of sheet metal, as described in the preamble of claim 1.
- DE 38 24 734 AI and DE 38 30 488 AI discloses a manufacturing device 1 for metalworking, in particular a folding machine or a bending press with an electronic tool recognition system.
- a bending tool set for these production devices consists of at least one upper tool, in particular a punch, and a lower tool, in particular a die. These tools can also be segmented, i. be divided to facilitate their handling by smaller tool parts.
- at least one electronically detectable code carrier is attached, which contains all geometry data that define the tool and the allowable tool load data.
- the code carrier can also be defined only by a tool identifier if the tool data are stored in the machine control. In order to be able to read the code carriers in the tools, in the area of the tool receiving devices, i.
- At least one read head is mounted on the press beam and on the press table. With these reading heads placed per code carrier, the tool data or the tool identifiers of the individual code carriers are determined and transferred to the machine control.
- the disadvantage here is that a plurality of read heads is required in order to detect any bending tool in a variety of possible individual tools, which u.a. a relatively high cabling or wiring effort is required.
- a new bending tool set does not correspond to the predetermined arrangement of the read heads due to a different pitch, so that the arrangement of the individual read heads either changed or the placement of the code carrier must be adjusted on the bending tools, which entails a high manipulation effort ,
- the present invention has for its object to provide a manufacturing device for forming workpieces made of sheet metal, in which an electronic detection and / or position detection of the bending tools used is reliably executable even with a variety of configuration options and thereby no costly Umrüst- or fitting work on the tool recognition system, in particular its construction, are required.
- An advantage resulting from the features of the characterizing part of claim 1 is that only a single detection device for the electronic information carrier is required to electronically detect the bending tools of the press bar and / or the press table. Furthermore, no or hardly any conversion work is required to ensure a reliable detection of the individual, provided for a labor use bending tools with changed tool configuration.
- the specified production facility is therefore overall very flexible with regard to the possible tool spacing or number of tools and their secure, electronic detection. It is furthermore of particular advantage that the individual tool data or tool identifications can be detected consecutively by the positively guided adjustability of the detection device and thus the sequence of the bending tools used can also be determined in a simple manner by the control device. This determination takes place without a precisely defined assignment of a plurality of inputs to the electronic control device.
- Another advantage of the embodiment according to the invention is that the maximum number of detectable tools can be determined by hardware-related limits, such as the sequential read-in of the individual information carriers. a limited number of available inputs, is no longer limited. The number of detectable bending tools is thus relatively easily expandable upwards. Furthermore, a position determination of the individual bending tools can also be simplified or improved with the marked embodiment. Such a position determination can be provided in combination or alternatively to a tool recognition.
- a further embodiment according to claim 2 is advantageous, since thereby a reliable signal or data transmission from the detection device to the control device and possibly vice versa can be achieved and the risk of external influences is low or with simple technical measures, such as shielding measures, can be minimized.
- a further advantage is an embodiment according to claim 3, since a relatively wide adjustment range can be created within which a reliable signal or data transmission can still be achieved with low cabling or wiring complexity.
- an embodiment according to claim 5 is advantageous because hereby larger adjustment paths or tool lengths can be easily bridged and a cost-effective adjustment and / or guiding device can be created.
- Another advantage is also a development according to one of the characterized in claim 6, alternative embodiments, as this is a simple mechanical structure is created, with which the detection device can be moved over in comparison to the dimensions of the detection device extensive routes with sufficient guidance accuracy.
- An alternative embodiment is characterized in claim 7. It is advantageous that a relatively precise positive guidance for the detection device along the possible tool length is created.
- an automatable, bidirectional adjusting movement for the detection device can be achieved in an advantageous manner. Furthermore, when forming a cable connection, harmful cable distortions are excluded and, moreover, a double or multiple query of the individual information can be obtained. be carried out in a relatively short time.
- the demands on the adjustment or guiding accuracy of the adjusting and / or guiding device are low and, in addition, signs of wear due to rubbing or grinding components can be avoided.
- At least the communication or transmission path for information or data signals between the detection device and the information carrier can be made contactless or wireless.
- Electrical operating energy for the passive information carriers is preferably transmitted wirelessly between the detection device and the information carriers via these transmitting and / or receiving devices or else via independent transmitting and / or receiving units.
- information carrier can be easily read or recorded even at low management and adjustment accuracy of the adjustment and / or guide device.
- An inexpensive and reliably detectable, passive position-determining element is specified in claim 15.
- a contact or non-contact detection of the presence and / or position of a bending tool is made possible by the embodiment of claim 16 with inexpensive and reliable means.
- the current position of a particular bending tool within the possible tool length for example, starting from a defined tool start point, determined and evaluated or taken into account for subsequent or to be initiated operations.
- a multi- or Herfiintechnisches namely on the one hand for determining the position of the various bending tools and on the other hand as adjustment drive for the automatically movable detection device, can be achieved by the embodiment according to claim 18.
- tow cable arrangements between the movable detection device and a fixed machine part can be made unnecessary, whereby a secure, wired signal transmission from the movable detection member is made possible to a fixed or fixed point on the manufacturing facility even in confined spaces.
- a functionally reliable and simple forwarding of the electrical signals from the transport member to the control device and / or vice versa is made possible by the embodiment of claim 20 and / or 21.
- an embodiment according to claim 23 is advantageous because it ensures a slip-free adjustment of the detection device along the required tool length and determined by simple technical means a displacement of the detection device relative to the tool length or to a defined zero or starting point or monitored can.
