DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0069] The bending press 11 shown in FIG. 1 has a top beam 21 and a lower beam 26, wherein the top beam 21 can be traversed relative to the lower beam 26 for bending metal sheets. Depending on the type of the bend to be created, the corresponding bending tools are provided on the top beam 21 and the lower beam 26. The controller, the drive means for the top beam 21 as well as the other usual components of a common bending press 11 are provided within the housing 13 of the bending press 11.

[0070] In the example at hand, two drawers 31, 31A, which are designed for accommodating bending tools, are arranged on both sides next to the lower beam 26. The drawers 31, 31A are integrated in the housing 13 of the bending press 11.

[0071] Each drawer 31, 31A is guided via guide rails 34 on a correspondingly designed drawer mechanism, which is provided in the housing 13 of the bending press 11. Provision is advantageously made for a pull-out stop, which prevents that the drawer 31, 31A can inadvertently be pulled too far out of the housing 13 of the bending press 11. Provision can also be made for fixing locks for the drawers 31, 31A, in order to be able to fix the latter in certain positions relative to the housing 13 of the bending press 11 and to thus be able to prevent an unintentional closing thereof.

[0072] In this example, the drawer 31 can be traversed via a motor unit 48, wherein this motor unit 48 is controlled via a sensor 49—here designed as motion sensor.

[0073] The drawer 31 is provided with a lock 35. The drawer 31 can be locked or blocked, respectively, by means of the corresponding key as locking means.

[0074] Each drawer 31, 31A further has an accommodating area 32, in which provision is made for a plurality of bending tool accommodating units 36 for bending tools (FIGS. 2 and 3). Each of these bending tool accommodating units 36 has an accommodating holder 37 for a bending tool, in which the bending tool is held in a clamped manner for example. The accommodating holder 37 is made of a foam, for example, and has—in this example—three accommodating slits 39 for accommodating at least three bending tools.

[0075] Provision is in each case made on each bending tool accommodating unit 36 for a display unit 43, which runs along the longitudinal extension thereof, as well as a display unit 44, which runs along the transverse extension thereof. These display units 43 and 44 are in each case designed as LED light strips, wherein the individual LEDs can be controlled separately. Via these LEDs, it is displayed to the operator, for example, where he is to store a bending tool, which is no longer needed. For example, it can also be displayed to the operator via these LEDs, which bending tool from the bending tool accommodating unit 36 he is to arrange in the lower beam 26 or the top beam 21 for the next bending process.

[0076] Each of the bending tool accommodating units 37 can be moved from the accommodating area 32 of the corresponding drawer 31. In the example at hand (see in particular FIG. 4), each bending tool accommodating unit 37 can be pivoted out of the accommodating area 32 of the drawer 31 about a pivot axis 38, which is defined by a bolt here.

[0077] Provision is furthermore made in the drawer 31 for holding devices 40 for temporarily holding the bending tool accommodating units 36. The holding devices 40 have for example a magnet 42, which is arranged on the bending tool accommodating unit 36, and a counter magnet 41, which is arranged on the inner side of the accommodating area 32 of the corresponding drawer 31. The magnet 42 as well as the counter magnet 41 are designed in such a manner that the bending tool accommodating unit 36 is temporarily held in response to opening and closing the drawer, while the available holding force between the magnet 42 and the counter magnet 41, however, can be overcome easily by the operator and advantageously without much expenditure of force.

[0078] With regard to the illustration at hand in the upper area of the drawer 31, said illustration has a part accommodating unit 33, which covers the drawer 31 from the top and which at least partially protects the bending tools, which are present in the bending tool accommodating units 36. This part accommodating unit 33 serves for example to accommodate tools for the machine maintenance or for arranging or changing, respectively, bending tools on the top beam 21 and/or the lower beam 26. Measuring means, in particular the measuring means, which are required in response to the bending of the metal sheet, can further also be stored in the tool accommodation 33. All of the work equipment required for operating the bending press 11 are thus directly available to the operator thereof at the bending press 11.

[0079] Provision is made in the part accommodating unit 33 for an induction surface as an electrical interface 121, via which devices, which are capable of induction, can be charged as needed. Provision is furthermore made for an electronic interface 123—here in the form of a USB port, via which for example data can be exchanged with the drawer 31 and/or with the bending press 11.

[0080] Provision is further made in or at the part accommodating unit 33, respectively, for a control electronics 125, which can perform controls at the bending parts and/or at the bending tools via corresponding sensors 127 or devices (e.g. a camera). For example, this control electronics 125 serves to capture an actual state of a bending tool.

[0081] The drawer 31 can furthermore be pivoted with respect to the housing 13 of the bending press 11 about the axis of rotation 46 and can be moved along the latter relative to the housing 13 of the bending press 11 (see FIG. 4). The drawer 31 can accordingly be positioned along the axis of rotation 46 in the height as needed. The drawer 31 can also be pivoted in such a manner that the operating space of the operator of the bending press 11 is limited less by the drawer 31 or is only limited slightly, respectively.

[0082] In the case of the bending press 51 shown in FIG. 5, drawers 71, 71A and 71B, which are designed to accommodate bending tools, are arranged on both sides next to the lower beam 66 and next to the top beam 61. Based on the illustration at hand, the drawer 71 is arranged to the right of the lower beam 66. Based on the illustration at hand, the drawer 71A is arranged to the right of the top beam 61. Based on the illustration at hand, the drawer 71B is arranged to the left of the lower beam 66 as well as next to the top beam 61 and, in the example at hand, extends virtually cross the entire height of the bending press 51. The drawers 71, 71A and 71B are integrated in the housing 53 of the bending press 51.

[0083] Provision is made on the drawer 71 for a display unit 72, which is designed as screen. The operator can read the type and/or the number of the bending tools located in the drawer 71 on the integrated display unit 72. These data were provided to the controller of the bending press 51 in advance, for example, or were automatically captured via corresponding sensors. The drawer 71 itself can have a storage/control unit, which stores the data in connection with the parts accommodated in the drawer 71 or removed therefrom and has them displayed.

[0084] FIG. 6 illustrates a drawer 81, which can be separated from a bending press. This drawer 81 has a traversing unit 83, which comprises a plurality of rollers 84.

[0085] Provision can be made on this drawer 81, but also on the other embodiments of the drawers 31, 71, 91, 101 described herein for connecting parts for connecting a plurality of these drawers to one another. Bending cells can be realized with this by means of a plurality of bending presses for example, which are designed for a continuous processing of bending parts in these bending presses. These connecting parts are designed, e.g., as conveying devices, so that bending parts can easily be transported or transferred, respectively, from one bending press to the next bending press.

[0086] Provision is made in the drawer 91 (see FIG. 7) for two assistance devices 93 and 96. The assistance device 93 is designed as a robot 94. The assistance device 96 comprises a power generating device 97 in the form of a compressor and a power supply device 98 in the form of a compressed air tube.

[0087] As shown in FIG. 8, the drawer 101 has a support element 103 arranged thereon, which is illustrated in the stored state (dashed line) on the one hand and in the use state (continuous line). The support element 103 comprises a schematically illustrated hook element 104, via which the support element 103 can be arranged on the drawer 101 in one of the two shown positions. By means of a support 105, which can advantageously be adjusted in its length, the angular orientation of the support element 103 can be adapted relative to the drawer 101.

[0088] The drawer 101 further has a support element 106 arranged therein, which is also illustrated in the stored state (dashed line) on the one hand and in the use state (continuous line). The support element 106 can be pivoted relative to the drawer 101 about a pivot axis 107. Provision is made for a drive device 108, here a gas pressure spring, for pivoting the support element 106. The drive device 108 is advantageous controlled, so that any angular orientation (angle α) of the support element 106 relative to the drawer 101 can be set. Provision is advantageously made for an automatism, so that the support element 106 transfers into a position vertically to the drawer 101 in response to the activation of the drive device 108—without mutual influencing by the operator or a controller.

[0089] Provision is made on the support element 103 for a conveying device 111, which is designed in a chute-shaped manner, for bending parts and/or bending tools, the incline of which can be set relative to the support element 103. The drawer 101 also has a further conveying device 113, which is designed as conveyor belt. The conveying device 111 provided on the support element 103 can also be designed as conveyor belt—an alternative not illustrated here—and the conveying device 113 could also be designed as chute.
