Abstract

The invention relates to production unit (1), in particular a bending press (2), for forming workpieces (3) of sheet metal, having two press beams (15, 16) which are displaceable relative to one another by means of a drive mechanism (53) and can be used to obtain a required tool length (42) by fitting a variable number of bending tools (36, 37). To enable them to be identified and/or their positions detected on an at least partially automated basis, the inserted bending tools (35, 37) have unmistakable codes in the form of electronically detectable information carriers (43). To this end, an electronic detection device (44) for detecting a plurality of information carriers (43) connected to a control device (46) or a control and/or evaluation device (47) connected to it co-operates with the first and/or second press beam (15; 16), and at least one displacement and/or guide mechanism (45) is provided which extends essentially parallel with the achievable tool length (42) and accommodates the detection device (44). The codes or data and/or detection signals of a plurality of information carriers (43) can be detected in sequence during a relative displacement of the detection device (44) along the displacement and/or guide mechanism (45) and can be transmitted to the control device (46) or the control and/or evaluation device (47) co-operating with it.

Description

Manufacturing device, in particular press brake, with electronic tool detection

The invention relates to a Fertigungseimichtung, 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. In the individual tools at least one electronically detectable code carrier is attached, which contains all geometry data that define the tool and the allowable tool load data. Alternatively, 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. In addition, it may happen that 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.

This object of the invention is achieved by the technical features of a production device according to claim 1.

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.

Of particular advantage are the measures according to claim 4, as a result in easier

It is ensured in such a way that the respective data or identifiers of the plurality of information carriers can be sequentially inserted successively on the detection device or taken up by it. The risk of erroneous captures is thereby minimized and also favors the determination of the order or arrangement of the individual tools.

Furthermore, 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.

Of particular advantage is also an optional development according to claim 8, since thereby the detection process can be performed at least partially or to a large extent automated.

By the optional development according to claim 9, 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.

Due to the embodiment according to claim 10, 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.

Advantageous in terms of low cost are the virtually maintenance-free, electronic information carrier according to claim 11.

Due to the construction according to claim 12, 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. In addition, such information carrier can be easily read or recorded even at low management and adjustment accuracy of the adjustment and / or guide device.

Of particular advantage is also a possible embodiment according to claim 13, as a result variable data or cumulative history data can be deposited as needed or requirement via the detection device in the storage device, which is always current information or data present at the information carrier.

Furthermore, the possible development according to claim 14 is advantageous, since it is possible with simple means a sufficiently accurate determination of the relative position of bending tools within the possible tool holding length. At the bending tools or position detection elements themselves doing any adjustment or adjustment must be made in an advantageous manner.

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.

Due to the configuration according to claim 17, 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 mehrfiinktionale use of Versteilantriebes, 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.

Due to the possible embodiment according to claim 19 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.

The measures according to claim 22, a reliable electrical isolation between the transport member and the machine frame is achieved by simple means.

Finally, 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. The invention will be explained in more detail in the following anliand the embodiments illustrated in the drawings.

As an introduction, it should be noted that in the differently described Ausfuhamgsformen the same parts are provided with the same reference numerals or the same component names, the revelations contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or the same component names transmitted. Also, the position information selected in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to a new position analogous to the new situation. Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions.

1 and 2 is a manufacturing device 1, in particular a press brake 2, for the forming, in particular of workpieces 3, e.g. to housing parts 4, profiles, etc., shown. Furthermore, these manufacturing devices 1 are also used for the production of elongated profiles, e.g. Angle profiles, U-profiles, Z-profiles, etc. used with a generally very large length / aspect ratio.

A machine frame 5 of the manufacturing device 1 consists essentially of two parallel and spaced C-shaped stator side walls 6, 7, which are used directly or as needed, e.g. supported on a footprint 9 via damping elements 8 or in a further embodiment, as shown by way of example, on a common

Base plate 10 attached, in particular welded to it. Furthermore, the stator side walls 6, 7 are connected to each other at a distance 11 via vertical to a vertical center plane 12 extending wall parts 13.

With respect to a to the footprint 9 parallel working plane 14, the

Manufacturing device 1, two opposing press beams 15, 16, which extend over a length 17, which is generally determined by the intended machine size or the intended working length for bending the workpieces 3.

The contact surface 9 facing the press beam 15 is via a mounting arrangement

19 on the machine frame 5, preferably attached directly to end faces 20 of the bottom plate 10 associated legs 21 of the C-shaped stator side walls 6, 7, in particular by means of welded connection. On side surfaces 22, 23 of beabstan- to the Aufstandsfläclie 9 Deten legs 24 of the C-shaped stator side walls 6, 7 are acted upon by a pressure medium actuators 25, 26 of a drive assembly 27, formed from double-acting hydraulic cylinders 28, respectively. Adjusting elements 29, for example piston rods of the hydraulic cylinders 28, are drivingly connected to the guide bars 30 of the machine frame 5 in a direction perpendicular to the working plane 14 perpendicularly mounted press beam 16 via spherical plain bearings 31 and, for example, bolts 32. The press beam 15 and the press beam 16 extend over the length 17 approximately symmetrically and in the direction perpendicular to the center plane 12, wherein the length 17 is slightly larger than the distance 11.

On facing each other and to the working plane 14 parallel end faces 33, 34, the press bars 15, 16 tool receiving devices 35 for supporting and releasable attachment of bending tools 36, 37 on. As known from the prior art, these bending tools 36, 37 generally form a bending die 39 designed as a die 38 and a bending punch 41 designed as a male 40. The tool receiving devices 35 on the press beams 15, 16 are on the one hand designed for releasably securing the bending tools 36, 37, on the other hand they form support surfaces for transmitting the bending forces.

From the prior art, it is also known to divide the bending tools 36, 37 into sections, resulting in a slight variability for a tool length 42, in order to adapt to the respective requirements can or to the conversion of the manufacturing device 1 or the Exchange of bending tools 36, 37 easier to make. In particular, by a juxtaposition of several bending tools 37 on the upper press beam 16 and by a juxtaposition of several corresponding bending tools 36 on the lower press beam 15 and on the press table, the required tool length 42 can be set or configured by an operator of the production device 1.

It is also possible that the operator on the lower press bar 15 and / or on the upper press bar 16 within the required tool length 42 in their properties or

Parameters according to a specification aware of each other slightly different bending tools 36 and 37 lined up. For example, at least one of the outer bending tools 36 or 37 may have different dimensions or a slightly different geometry. As a result, it is possible, for example, to design the end region of a work piece 3 to be shaped somewhat differently than the middle region or the distal end region of this work piece 3. It is also conceivable to shape the middle area differently than the two end areas of the same. Also, depending on the tool length 42 slightly different pressing pressures or to achieve the most exactly constant bends or shapes of the workpieces 3, it may be appropriate to make the individual, juxtaposed bending tools 36 and 37 within the tool length 42 different. As a result, any differences in pressure or slight deviating movements of the production device 1, in particular the press beams 15,

16, are at least partially offset at the high pressing forces, whereby an improved, in particular a dimensionally accurate, bending or shaping result can be achieved. The individual bending tools 36 and 37 to be joined to one another within the desired or required tool length 42 hardly differ in the geometrical dimensions and these slight differences in dimensions are evidently only difficult or not recognizable. The differences between the individual bending tools 36 and 37 for forming the bending die 39 and the formation of the punch 41 move in the range of a few tenths of a millimeter to a few millimeters and are therefore evidently hardly ascertainable.

For distinguishing marking these different bending tools 36 and 37 may be provided to form a defined tool set in the manner of a Biegegesenkes 39 or a specific punch 41 with color codes and / or numeric or graphic-based information. The togetherness of a corresponding kit for the desired bending die 39 or for the desired bending punch 41 can be visually recognized by the operator on these usually visually detectable markings.

Alternatively or in combination with these identifiers visually detectable by the operator, the individual bending tools 36 for forming the desired bending die 39 and / or the bending tools 37 for providing the corresponding bending punch 41 are provided with at least one electronically or electrically detectable information carrier 43. This information carrier 43 for the individual bending tools 36; 37 or for the individual segments of the bending die 39 or the punch 41 comprises either data on relevant intrinsic Schaften or specifications of the respective bending tool 36, 37 or the information carrier 43 includes only a distinctive, quasi-identifying identifier, behind which a particular record with a variety of data on the bending tool 36; 37 stands. This means that when a memory-less, distinctive or distinctive identifier is assigned to the information carrier 43, a large amount of data concerning the peculiarity of the particular tool with relatively small amounts of data or low memory requirements can be defined or quasi deposited directly on the bending tools 36 and 37, respectively. Especially if only small amounts of data are to be transmitted or read out of the information carriers 43, the use of an electronic identification mark as information carrier 43 for identifying the respective bending tool 36 or

37 a concrete and detailed deposit of data on the bending tools 36; 37 preferable. In particular, the information carrier 43 is designed as an electronically detectable characteristic, for example as an electrical resonant circuit with defined properties, which describes the respective bending tool 36 or 37 quasi indirectly, by the externally lying, associated data set for this characteristic of an electronic

Circuit of a control utilized or processed electronically.

For electrical or electronic recording of the respective characteristics or data of the individual information carrier 43 in the individual bending tools 36 and / or in the individual bending tools 37 at least one relative to the machine frame 5 adjustably mounted detection device 44 is formed. This electrical or electronic detection device 44 for the individual information carrier 43 can thereby by hand, i. manually, relative to the bending tools 36; 37 and their information carrier 43 are adjusted and / or moved automatically, as will be described in detail below.

The detection device 44 is associated with an adjusting and / or Fülπungsvorrichtung 45 and mounted relative to this adjustable to be moved along the individual bending tools 36 and 37 of the bending die 39 and the punch 41 can. In spite of a detection device 44 which is relatively limited in the detection range or in the detection range, reliable detection of the information carriers 43 extending or dividing over comparatively large areas can be achieved by the relatively movable detection device 44 assigned to the adjusting and / or guiding device 45 be achieved.

As has been illustrated schematically in FIG. 1, it is also possible, by means of only one movable or adjustable detection device 44, both the information carrier or carriers 43 of the punch 41 and the information carrier or carriers 43 of the bending die

39 to capture or read. The reading of the identifiers or data of the information carrier 43 is preferably carried out without contact or contact. In particular, the identifiers or data are received and received by the detection device 44 via a so-called "air transmission path." That is, a defined one between the bending tools 36 or 37 or their information carrier 43 and the adjustable detection device 44

Air gap or free space is formed, via which the individual license plate or data to the detection device 44 are transmitted.

An electrical or electronic control device 46 controls or controls at least the basic processes or functions of the production device 1. The detection device 44 for the individual information carrier 43 is connected to this control device 46 or one of these control device 46 associated control and / or evaluation device 47. Preferably, at least one line connection 48 is provided between the detection device 44 and the control and / or evaluation device 47 for forwarding the signals or data supplied or generated by the detection device 44. in the

In the area of the adjusting and / or guiding device 45, this line connection 48 can be formed by a trailing cable arrangement 49, via which a defined adjustment range for the detection device 44 is achieved and a preferably electrical, possibly also optical signal connection to the control and / or evaluation device 47 is ensured is. Such a tow cable arrangement 49 offers a reliable signal or data transmission starting from the detection device 44 to the electronic control and / or evaluation device 47 and vice versa. Of course, instead of forming a tow cable arrangement 49 with cable loops carried by carriages, it is also possible to provide a cable drum arrangement from which the tow cable can be removed and wound up. In particular, any trailing cable arrangements 49 for secured electrical or optical connection between the control device 47 and the detection device 44 can be used. The data or information or identifiers recorded by the detection device 44 are included in the control sequences or the available functions of the press brake 2 by the control and / or evaluation device 47 and / or by the actual control device 46.

The peculiarities or the respective specifications of the bending tools 36 and 37 used on the press brake 2 can be at least partially automatically detected by the detection device 44 and the adjusting and / or guiding device 45 and utilized by the preferably program-controlled or software-controlled control device 46 , In particular, the respective data or characteristics of the information carriers 43 influence this

Behavior or the work processes of the press brake 2 in the manner described below.

Preferably, the adjusting and / or guiding device 45 ensures a precisely defined adjustability of the detection device 44 along the elongated bending tools 36 and 37, which are usually composed of a plurality of individual tools. This ensures that none of the individual tools is skipped or overrun or otherwise skipped as may happen with a handheld acquisition device 44, such as a handheld scanner. By means of the adjusting and / or filling device 45 it is also ensured at all times that the detection device 44 always maintains a defined, fail-safe reading or recognition distance to the individual information carriers 43. Exceeding the maximum reading range or the maximum possible reception range would namely lead to an erroneous reading or to a gap-like detection of the individual, quasi-serially arranged information carrier 43 of the respective bending tools 36 and 37, respectively. This can be reliably prevented by the advantageous adjusting and / or guiding device 45.

For example, the adjusting and / or guiding device 45 can be provided by at least one guide element 50 running along the lower and / or the upper press beam 15, 16, e.g. in the manner of a guide rail or a guide shaft, be formed. Along this

Guide element 50 is a guide carriage 51 mounted linearly adjustable. On this guide slide 51, the detection device 44 is arranged or mounted comprising a transmitting and / or receiving device 52 for electromagnetic waves. By means of these transmission and / or receiving device 52 for realizing a radio transmission and / or a radio reception, the information carrier 43 in or on the individual bending tools 36 and 37 at least contact or contactless read, in particular detected.

Via the line connection 48 extending from the detection device 44 to the control and / or evaluation device 47, the corresponding information or signals are reliably relayed from the information carriers 43 over comparatively extensive distances. Preferably, the detection device 44 also includes a converter or amplifier for the signals to be transmitted from the information carriers 43 to the control and / or evaluation device 0 47.

If the data acquired via the detection device 44 or the information obtained from the characteristics do not match the required or predetermined values, in particular the desired values in the control device 46, then at least one reference or one or more indications will be provided

[5 Issue a warning message and, if necessary, interrupt the workflow of the pressbrake 2 or not initiate it at all. Damage to the press brake 2 or the bending tools 36; 37 avoided and the cause of committees or defective parts 3 are reduced. Likewise, this may cause injury to the operator as a result of overloaded and possibly breaking machine parts or parts 3

! 0 avoided or the risk of injury to the operator are at least reduced. In particular, it can be checked on the basis of the data obtained from the bending tools 36 and 37, whether the current configuration of the press brake 2 is suitable for the intended workflows or not. Only in the case of a positive control or comparison result can the work processes specified by a control program be executed or initiated.

Otherwise, an alarm or error message will be output and the press brake 2 will preferably be shut down or transferred to a safe operating state or held therein until the proper configuration or assembly with the required bending tools 36 or 37 has taken place. In particular, the actuators 25, 26 of the drive assembly 27 and / or an electromotive drive device 53 of a hydraulic

0 aggregates as long as not put into working movement, as long as the actual configuration with the stored preferably in a memory of the control device 46 and / or manually entered desired configuration. FIG. 2 shows a double embodiment of a detection device 44 with adjusting and / or guiding device 45 for the information carriers 43. In particular, a detection device 44 and adjusting and / or guiding device 45 for detecting a plurality of information carriers 43 in or on the bending tools 36 and 37 are respectively associated with the lower press beam 15 and the upper press beam 16. By allocating a detection device 44 to the upper, the bending die 41 forming bending tools 37 and by the allocation of a separate detection device 44 to the bending die 39 forming bending tools 36 can even at relatively low reading or detection sensitivity or low reception sensitivity proper sampling the individual information carrier 43 are ensured. Optionally, these two each assigned detection devices 44 may also be placed on a common adjustment and / or guide device 45. The two detection devices 44 are always moved simultaneously and absolutely the same.

Each of these detection devices 44 has an electromagnetic wave transmitting and / or receiving device 52, which can be received by the information carriers 43. In response to a polling and / or powerless received signal, i. Signal providing energy, send the information carrier 43 their respective identifier or the deposited data to the requesting issuing the corresponding detection device 44 or in the vicinity of surrounding area so that they can be picked up by the detection device 44. Each of the detection devices 44 in the region of the upper and lower press beams 15, 16 or in the area of the tool receiving devices 35 for the bending tools 36, 37 is connected via a respective cable connection 48, in particular via a cable connection with the control device 46 or its control and / or evaluation device 47 connected.

By the double or double execution of the detection device 44 or by the assignment to the upper and lower bending tool 36, 37 can be checked whether associated bending tools 36, 37 and a certain bending punch 41 and a dazuge- hearing impaired 39 on the Press brake 2 is present. Otherwise, it is prevented by the control device 46, that with the press brake 2, a shaping or Abkantvorgang is performed. The risk of damage to the mechanical components of the production facility 1, the production of unusable workpieces and the injury risk for the user can be avoided or at least limited by the at least partially automated tool recognition - as mentioned above.

For scanning the information carrier 43 or detecting the existing along the current tool length 42 bending tools 36 and 37, the electronic detection device 44 along the adjustment and / or guide device 45, for example, be manually adjusted. It is necessary to move the detection device 44 at least once along the currently existing tool length 42 at least once. During the positively guided adjusting movement of the detection device 44 along the adjusting and / or guiding device 45, the respective information carriers 43 are preferred

Bending tools 36 and / or 37 scanned or scanned and continuously transmitted to the control device 46 and the control and / or evaluation device 47. Preferably, the transmission of these identifiers or data to the control and / or evaluation device 47 takes place "on the fly", ie without significant intermediate storage in the detection device 44. The recording of the respective information or data of the information carrier 43 during the more or less continuous, linear adjustment movement of the detection device 44 relative to the information carriers 43 allows rapid detection of the respective configuration of the bending punch 41 and / or the bending die 39. This short-term tool recognition would not be possible with a discontinuous stop-and-go operation of the detection device 44 ,

Alternatively or in combination with a manual adjustment of the detection device 44 along the adjusting and / or guiding device 45, it may be useful to associate the detection device 44 with an automatically controllable drive device 54, as can be seen from the schematic representations according to FIGS. 3 and 4 ,

This embodiment of an adjusting and / or guiding device 45 according to FIGS. 3 and 4 shows the drive device 54 for the detection device 44 in conjunction with the lower press beam 15 or in combination with the press table. Of course, it is also possible in a similar or similar manner, such a drive device

54 for a detection device 44 to the upper press bar 16 - Fig. 2 - assign. The mechanical and electromechanical components of this drive device 54 -as shown in FIG. be arranged on the machine frame 5 of the press brake 2, or, as illustrated in FIGS. 3 and 4, at least partially integrated in the interior of the load-bearing or load-bearing components of the generic machine.

5 This drive device 54 comprises according to the illustrated embodiment, a flexible transport member 55 in the form of a belt, a chain or a rope. Preferably, the transport member 55 is endless and guided by at least two rotatably mounted deflection pulleys 56, 57, wherein the designed as an endless loop transport member 55 between the guide plates 56, 57 is at least slightly stretched. The defined between the 0 deflection 56, 57 adjustment away for the fortified on the transport member 55

Detection device 44 extends at least over the maximum possible tool length 42 of the manufacturing device 1, in particular the press brake second

Alternatively, it is also possible to guide the flexible transport member 55 by two mutually spaced 5 arranged winding coils, in which case the two ends of the transport member 55 are attached to a respective reel spool and the transport member 55 is at least slightly tensioned between the two reel spools. In this case, the flexible transport member 55, together with the detection device 44, can be adjusted bidirectionally and also largely linearly along the required adjustment path by counteracting the same upward and downward movements of each reel spool.

An adjusting drive 58 for the transport member 55 is preferably formed by an electric motor drive. Alternatively, it is of course also possible to use pneumatic or hydraulic drives for the belt or belt-shaped transport member 55.

> 5

The automatically controllable or drivable adjusting and / or guiding device 45 for the detection device 44 in this case therefore comprises the flexible, preferably endlessly circulating transport member 55 with the detection device 44 mounted thereon and an electrically controllable drive unit 55 connected to this transport member 55.

Preferably, this adjusting drive 58 is reversible in its direction of rotation or movement, so that a bidirectional adjustment movement of the detection device 44 along the maximum possible tool length 42 is achieved. The bidirectional, reversible operation of the adjusting and / or guiding device 45 or the endless Transport member 55 and Versteilantriebes 58 is preferable to a circulating, unidirectional operation when the corresponding signals or data via the line connection 48 between the detection device 44 and the electronic control and / or evaluation device 47 and the control device 46 of the press brake 2 the. Spiral entanglements of the cable connection preferably made via a cable 48 köm thereby be prevented.

Here too, the line connection 48 from the detection device 44 to the control device 46 at least in the region for bridging the maximum possible adjustment path of the adjusting and / or guiding device 45 comprises a tow cable arrangement 49 in FIG

Form of slidably suspended cable loops or a cable and cable unwinding device in the manner of a drum store for the corresponding cable.

As is clear from the synopsis of FIGS. 3 and 4, the adjusting and / or guiding device 45 for the detection device 44 is embedded in the press table or at least partially integrated therein. In particular, at least in the tool receiving device 35, a groove-shaped recess 59 is formed, in which the transport member 55 extends with the detection device 44 mounted thereon. The recess 59 extends with respect to its longitudinal direction approximately over the maximum possible tool length 42 in order to ensure a complete recording or recording of the respective held by the tool receiving device 35 bending tools 36. This depression 59 in the tool receiving device 35 can also extend into the press beam 15 or into a table top 60 of the press table in order to be able to accommodate relatively generously dimensioned adjusting and / or filling devices 45. As a result, in the press beam 15 or in the press table, a largely outwardly closed hollow chamber 61 can be formed, in which the adjusting and / or guiding device 45 or at least its transport member 55 and the detection device 44 are securely received against external influences or force effects. So it is also possible to arrange the deflection pulleys 56, 57 at the frontal and distal end portions of the press table and only to guide the endless transport member 55 together with the detection device 44 in the interior of the machine frame 5. The dimensions of the Holilkammer 61 can be reduced thereby, whereby the stiffness of the form of the press table or press bar 15 is hardly affected. Instead of a bearing of the deflection pulleys 56, 57 on horizontally oriented axes of rotation 62, 63, it is of course also possible to provide vertically oriented axes of rotation 62, 63 for the deflection pulleys 56, 57. Specifically, in a quasi-horizontal bearing of the hubs 56, 57, a half or a strand of the circulating transport member 55 may be performed outside the load-bearing machine frame 5.

As further illustrated schematically, the axes of rotation 62, 63 for the deflection pulleys 56, 57 may be mounted between the top of the table top 60 and the underside of the tool receiving device 35. Thereby we achieve a simple assembly and a problem-free accessibility to the adjusting and / or guiding device 45 for possible maintenance, adaptation and / or control purposes.

The groove-shaped recess 59 in the tool receiving device 35 may also be stepped from the top of the tool receiving device 35 in the direction of the support plane of the machine frame 5 in order to support or support a plate-like cover element 64. This covering element 64, which can be inserted and removed from the indentation 54, causes a quasi-spatial separation in the recess 59 between an upper tool receiving groove 65 and the underlying receiving or hollow chamber 61, which at least for receiving the ribbon-shaped or rope-shaped, flexible transport member 55 is provided together with the detection device 44.

The plate-shaped covering element 64 between the hollow chamber 61 and the tool receiving groove 65 for the bending tools 36 prevents or minimizes contamination of the transporting member 55 or the detecting device 44 located beneath the bending tools 36. Furthermore, this separating or covering element 64 can be used to interpose the tool - Aufhauptut 65 and the hollow chamber 61 are prevented for the detection device to be relatiwerstellbare 44 that the detection device 44 hooked with the bending tools 36 and the information carriers 63 used when the transport device 44 is guided along the information carriers 43 and the bending tools 36 relatively close. By removing the cover 64, it is then possible in a simple manner to gain access to the detection device 44 or to the transport member 55 and / or to the other components of the adjustment and / or guide device 45. FIG. 5 illustrates a further embodiment of a tool recognition system for a production device 1, in particular for a press brake 2 or a so-called press brake. Due to the better clarity, the presentation of cladding or coverings has been dispensed with and this figure is greatly simplified and schematic in order to simplify the understanding of the relationships.

Here, the adjusting and / or guiding device 45 for the detection device 44 is assigned to the upper press bar 16 next. Here, too, the adjusting and / or guiding device 45 extends substantially parallel to the achievable tool length 42 and carries the contactless or contactless detection device 44 for the information carrier 43 associated with the various bending tools 37. Thus, either by manual and / or or the identifiers or data of a plurality of information carriers 43 are successively detected and transmitted to the control device 46 or an associated control and / or evaluation device 47 by an automated, motor-related relative position of the detection device 44 along the adjusting and / or guiding device 45 in order to process or utilize the corresponding information from the control device 46 or the control and / or evaluation device 47.

The signal or data transmission from the movable detection device 44 to the electronic control device 46 takes place at least in sections via the line connection 48. For the signal transmission from the movably mounted detection device 44 to a stationary point on the machine frame 5 in this case a sliding contact arrangement 66 is formed. This sliding contact arrangement 66 comprises a sliding contact 67 attached to the machine frame 5 or on the press beam 16 and at least one with this

Sliding contact 67 in electrically conductive interconnect conductor 68 in or on the transport member 55. Preferably, this conductor 68 closes on the revolving or endless transport member 55 flush with the top from. If appropriate, the at least one printed conductor 68 can also be arranged in a groove-shaped depression of the belt-shaped or belt-shaped conveying member 55.

Via these at least one conductor 68, electrical signals can be transmitted from the detection device 44 via the transport member 55 to the sliding contact 67 and further Sequence can be transmitted to the control device 46. Likewise, it is possible to transmit electrical signals to the detection device 44 in a corresponding manner electrical signals from the control device 46 via the line connection 48, the sliding contact 67 and the conductor 68 on the transport member 55. For this purpose, electrical inputs and / or outputs of the detection device 44 with the at least one conductor 68 in or on the transport member 55 in electrically conductive connection. This conductor 68 has a high flexibility and can be formed as a thin-layered sheet of copper or by another electrical conductor. The sliding contact 67 is in any case connected to the control device 46 or the associated control and / or evaluation device 47 via the line connection 48 in an electrically conductive connection.

It is expedient to contact the printed conductor 68, starting from the upper side of the conveying member 55, and to electrically isolate at least one printed conductor 68 from the deflection disks 56, 57 so that the electrical signals to be transmitted on the at least one printed conductor 68 do not impact the machine frame 5 are transmitted. The reference or reference potential of the electrical signals can be formed by a so-called ground connection on the machine frame 5. If this is not desired, at least two electrical conductor tracks 68 may be embodied on the transport member 55, to which a multiple sliding contact arrangement 66 is assigned.

Alternatively, it is also possible to form the belt or belt-shaped transport member 55 itself as an electrical conductor, so that this also represents the electrical conductor 68. In particular, the transport member 55 may be designed as a metallic rope, which is in electrical connection with the sliding contact 67. Specifically, the electrically conductive transport member 55 is electrically isolated from the machine frame 5 by, for example, the deflection discs 56, 57 of non-conductive material, such as plastic, and the transport member 55 itself not with the machine frame 5 and other parts of the press brake 2 in Touch stands. This can be accomplished by appropriate design and dimensioning of the adjusting and / or guiding device 45 in a simple manner. The machine frame 5 or parts thereof then carry the reference potential, so that between the machine frame and the transport member 55 electrical signals from the detection device 44 can be tapped or fed into this. According to an advantageous development, the information carriers 43 comprise at least one passive position detection element 69 or the information carriers 43 themselves constitute a passive position detection element 69. By means of this position detection element 69 it is possible to increase the relative position of the individual bending tools 36 or 37 relative to the maximum possible tool length 42 determine, ie that the position of the individual bending tools 36 and 37 in the tool receiving devices 35 relative to a starting point 70 or origin can be determined automatically. This starting point 70 can represent the so-called zero dimension of the production device 1 or the press brake 2.

Preferably, the passive position detection element 69 of the information carrier 43 is formed by a simple metallic aperture 71 or an equivalent metallic object, which represents a kind of marking or a mark for the presence of a bending tool 37.

The presence of such a shutter 71 can be detected by the detection device 44. In particular, the detection device 44 comprises an inductive sensor 72, preferably a so-called Hall sensor, which detects an approximation or a vorbebeifaliren the detection device 44 on the aperture 71 without contact. In particular, when the sensor 72 comes into the vicinity of the metallic diaphragm 71, a change in its electrical properties results, which is detected by the detection device 44 or the control and / or evaluation device 47 or the control device 46. This signal state change at the sensor 72 is an indication that the detection device 44 is currently in the vicinity of or directly at the metallic aperture 71. The diaphragm 71 is preferably coupled directly to the information carrier 43 or the diaphragm 71 may be formed, for example, by the housing or another metal element of the information carrier 43.

In addition to the recognition of the type or properties of the bending tools 36, 37, it is thus also possible, via the detection device 44 or the sensor 72 associated with it, for the

Use or use position of the respective bending tools 36; 37 to determine at least partially automated relative to the tool receiving device 35 and relative to the available tool length 42. For this purpose, the detection device 44 or the Control and / or evaluation 47 further includes a distance measuring device 73, via which the distance traveled by the detection device 44 adjustment path can be determined. Such distance measuring device 73 are based, as known per se, usually on the count of pulses, which are directly related to a certain distance or a certain Drehwinlcel or number of revolutions of a rotary motion, such as a motor.

Such pulse generator for the Wegmessvorrichtung 73 are formed for example by so-called incremental encoder or rotary encoder, as they are well known in the prior art.

In particular, if the adjusting and / or guiding device 45 comprises a stepper motor 58 as a stepping motor 74, the path measuring device 73 can use this stepping motor 74 to determine the distances traveled by the detection device 44 or the sensor 72 and consequently to determine the position of the individual information carriers 43 and bending tools 36, 37 with respect to a defined starting point 70. The determined actual positions of the individual bending tools 36; 37 can then from the control device 46 to control or monitor the proper working position of the bending tools 36; 37 are used.

6 and 7, a bending tool 36 equipped with an electronically or electromagnetically detectable information carrier 43 is illustrated.

The information carrier 43 is assigned to a lower base surface 75 of the bending tool 36. In particular, a groove-shaped recess 76 is formed in the base surface 75, in which at least one information carrier 43 is received. As a result, on the one hand, a simple, yet effective protection from damage and given a good

Detectability thereof achieved because the antenna or the transmitting and / or receiving device 52 of the information carrier 43 is only partially surrounded by the metal of the bending tool 36 and thus only slightly shielded.

Instead of forming a channel-shaped or groove-shaped recess 76, it is of course also possible to form a bore in the region of the base surface 75 or in the lower end of the tool receiving device 35 - Fig. 5 - and in this bore the information carrier 43 in such a way to ensure that it is protected from damage. The information carrier 43 is preferably interchangeable or detachably connected to the respective bending tool 36 as required. As a result, programming operations can be facilitated or damaged information carriers 43 can be replaced in a simple manner.

FIG. 8 shows a possible embodiment of an electronic information carrier 43. This information carrier 43 is designed as a so-called transponder 77 with integrated semiconductor circuits. As is known per se, this transponder 77 has a passive transmitting and / or receiving antenna 78, which is essentially formed by a coil arrangement with a plurality of conductor loops. Via this transmitting and / or receiving antenna 78, electromagnetic waves of a specific frequency can be received and / or transmitted. Optionally, as schematically shown, the transmitting and / or receiving antenna 78 may also comprise a coil core 79 in order to achieve a higher reception sensitivity or higher transmission power.

However, this transmitting and / or receiving antenna 78 can also serve as an energy source for an electronic circuit 80 of the transponder 77. In particular, when the transmitting and / or receiving antenna 78 is exposed to an alternating electromagnetic field, electrical energy is actually induced in the coil arrangement, which can be used to supply or operate the integrated circuit 80. In this electronic see circuit 80 may preferably be an energy storage, for example in the form of a

Condenser, be arranged to allow even after the elimination of the electromagnetic alternating field, a sufficiently long operating time after the transponder 77 is preferably designed to be battery-free. As a result, as long as possible freedom from maintenance and a relatively inexpensive, electronic information carrier 43 for the BiegeWerkzeuge 36; 37 - see Fig. 1 to 7 - achieved.

If the integrated circuit 80 is supplied with electrical energy via the transmitting and / or receiving antenna 78, it reads at least its identifier and / or the corresponding data from a memory device 81 assigned to it and, if necessary, transmits them via the same transmitting and receiving antenna / or receiving antenna 78 or an associated, under

Circumstances specially designed transmitting and / or receiving device 52 wirelessly to the detection device 44, as can be clearly seen from a comparison with the preceding figures. It is essential that the formed as a transponder 77 information carrier 43 only in a limited range of action or environment relative to the detection device 44 - see Fig. 1 to 5 - works. This means that the detection device 44 only receives the corresponding data or identifiers from the memory device 81 when the transponder 77 and the detection device 44 are arranged at a defined distance from each other or within the predefined, limited effective range. Depending on the sensitivity of the transponders 77 or the power of the detection device 44, this range is usually 1 cm to approximately 50 cm. 0

This information carrier 43 is explained below in conjunction with the preceding illustrations: In order to ensure with simple measures that the detection device 44 the respective identifiers or data of the successively arranged bending tools 36; 37 receives temporally successive received or can receive 5, it is advantageous if a maximum detection distance 82 between the adjustably mounted detection device 44 and an information carrier 43 of a nearest bending tool 36; 37 dimensioned smaller than a smallest possible distance 83 between two information carrier 43 of fully lined-up bending tools 36 and 37, as has been illustrated schematically in Fig. 4. By these structural precautions

.0, it is possible that the detection device 44 does not receive a plurality of identifiers of different information carriers 43 in parallel. As a result of the successive arrival of the individual signals or data, the order of the bending tools 36; 37 reliably determined.

Optionally, the information carrier 43 or the corresponding transponder 77 can also comprise a memory device 81 which permits both read and write accesses. This makes it possible to permanently store possibly changing data or properties in the storage device 81. In particular, an update of changing information or data in a simple manner, for example via the detection device 44, can be performed by means of write accesses to the information carrier 43 or its memory device 81 as required. In particular, when passing or positioning the detection device in the vicinity of an information carrier 43, the data content and / or data extent of its storage device 81 may be at least partially updated. The non-volatile memory device 81 is formed, for example, by a so-called EEPROM memory. Of course, any other rewritable memory devices 81 are conceivable, which do not require a permanent power supply to permanently store the corresponding data can.

The data stored in the memory device 81 preferably unchangeable or defined with a unique identifier may include, for example, information about the geometries or dimensions, the maximum load capacity and / or a production date or a product number. Optionally, at least some data about certain tool parameters can also be stored variably in the storage device 81. This is particularly advantageous when the bending tool 36; 37 was modified or modified by post-processing and these new tool parameters or geometries in the storage device 81 to be updated.

If appropriate, it is also possible to obtain information about the intensity of use or the number of previous inserts of the respective bending tool 36; 37 in the information carrier 43 continuously update or deposit. In particular, in combination with the control device 46, a service life management for the bending tools 36, 37 can be established and, in particular, when a maximum permitted service life or

Stand Quantity issued a corresponding warning or the implementation of further bending or deformation processes for workpieces are fully automatically prevented.

However, the individual data carriers or information carriers 43 can also be used to find a particular bending tool 36 in a machine shop or in a plurality of production devices 1 used; 37 to facilitate or support. In particular, it can be determined in which machine or on which production device 1 the desired bending tool 36; 37 is mounted. Furthermore, the expense for retrofitting the production device 1 can be optimized or reduced by the at least partially automated tool recognition.

Especially in the assignment or permanent deposit of so-called history data and their recording in the storage device 81 of the information carrier 43 is a so-called rewrite function of the storage device 81 of importance.

The various components of the so-called transponder 77 are preferably at least partially surrounded by plastic or synthetic resin or housed in a corresponding, shaping 5 housing.

Furthermore, the information carrier 43 may represent or comprise the passive, preferably metallic, position-decoding element 69. This passive position decoding element 69 basically serves only as a contactlessly detectable identification or marking for the presence of an information carrier 43 or a bending tool 36; 37. Optionally, a housing or the antenna of the information carrier 43 act as a passive position detecting element 69. Such information carriers 43 or position detection elements 69 cause electrical detection or position signals on the detection device 44, whereupon the latter and / or the control and / or evaluation device 47 - as explained above - the respectively current position of the individual Bending tools 36; 37 can be determined or calculated and these collected positions subsequently used as desired, such. visualized by means of a display device.

Via such an information carrier 43, on the one hand, the positions of each individual bending tool 36; 37 are detected relative to the tool holder or relative to the bending machine and on the other hand, the properties or parameters of the respective tool are determined automatically. As a third data or information group of an information carrier 43, the deposit of different history or usage data between bending tool 36 to bending tool 37 can be provided. > 5

Notwithstanding the exemplary illustration according to FIG. 8, it is of course also possible not to carry out the information carrier 43 and the passive position detection element 69 as a structural unit, but independently or separately from each other at different positions on a bending tool 36; 37 to provide. 10

As best illustrated in FIG. 1, in an alternative embodiment, the adjustment and / or guide device 45 may also include a spindle drive 84, as indicated by the threads shown in dashed lines. In particular In this case, the rod-shaped guide element 50 is formed by a threaded spindle 85 which is in motion connection with the detection device 44 or its guide carriage 51 via the thread. By means of a reversibly controllable, electromotive, pneumatic or hydraulic adjusting drive and / or by a hand crank, the detecting device 44 can be moved bidirectionally along the tool length 42 so that all of the existing information carriers 43 are detected or read out.

Instead of forming a cable connection between the detection device 44 and the control device 46 or the associated control and / or evaluation device 47, it is of course also possible to design the transmitting and / or receiving device 52 or a separate transmitting and / or receiving unit in such a way that that the relevant signals or data can be transmitted throughout wireless or contactless. In this case, it is then necessary to assign to the detection device 44 a mains-independent power supply device, for example in the form of accumulators or in the manner of an inductive energy transmission system.

The control device 46 and / or the communicatively connected with this control and / or evaluation device 47 are, as is known, for influencing the performance of the manufacturing device 1 as a function of sensory detected states of manual control commands and / or in a Storage device provided defaults.

For the sake of order, it should finally be pointed out that, for a better understanding of the structure of the production device 1, these or their components have been shown partially unevenly and / or enlarged and / or reduced in size.

The task underlying the independent inventive solutions can be taken from the description.

Above all, the individual in Figs. 1; 2; 3, 4; 5; 6, 7; 8 embodiments form the subject of independent solutions according to the invention. The relevant objects and solutions according to the invention can be found in the detailed descriptions of these figures. Signposting
