    A preferably shelf-like frame (3), on which a multiplicity of storage spaces (4) for bending tools (2) are arranged, at least one preparation path (10), preferably in the form of a tool guide (11), for issuing and / or retrieving bending tools ( 2), and at least a first transfer device (5) for transferring bending tools (2) between the storage locations (4) and a transfer point (6), characterized in that the bending tool storage device (1) between the transfer point (6) and the Provision path (10) has a rotating device (7) for rotating the bending tools (2).

    The invention relates to a bending tool storage device according to the preamble of claim 1.
    AT 516 624 B1 discloses a tool magazine with a large number of storage locations for storing forming tools for a forming press. A transport device for transporting the forming tools can be moved between the storage locations and a transfer position. An intermediate store is set up in the immediate vicinity of a forming press and is formed by two ring-shaped tool stores that can be rotated as a whole. Forming tools are transported between the tool magazines and the intermediate storage, each of which has its own frame and can also be used independently of one another. Such an arrangement requires a lot of space and is associated with considerable structural and control engineering. The storage density, i.e. the number of forming tools in relation to the space required is too small to meet the requirements of modern production.
    EP 2 946 846 B1 discloses a tool changing device which, similar to that disclosed in AT 516 624 B1, discloses an annular tool storage which can be rotated as a whole, i.e. all storage spaces are formed on the ring-shaped platform and rotate with every change. Such a construction requires a strong and reliable and therefore also expensive drive. The forming tools must also be moved (turned) when they are not needed.

    WO 2016109862 A1 discloses a loading device for loading a bending press with bending tools. This includes a tool store with a plurality of guide rails for holding and guiding bending tools and a transfer device for moving the bending tools. A clipboard with at least one guide rail is provided in order to expand the possibilities when maneuvering the bending tools. The tool storage and clipboard can be moved relative to each other.
    The object of the present invention is to overcome the disadvantages of the prior art and to provide a storage device which can be constructed in a compact design and by means of which the required space can be reduced and. The loading of bending presses or the replacement of bending tools should be faster. The storage density should be increased and the costs of production should be reduced.
    This object is achieved by a storage device mentioned at the outset in that the bending tool storage device has a turning device for rotating the bending tools between the transfer point and the preparation path.
    Due to the rotating device, the bending tools can be stored in the storage device in an orientation that is inclined to the preparation path. This means that the available space can be optimally used. In addition, the correct orientation and sequence of the bending tools for the bending press can be specified in the preparation path.
    The rotating device is a connecting link between the first transfer device and the preparation path. It transfers a bending tool (coming from the first transfer device) to the preparation path or turns a bending tool (to be transferred to the first transfer device) out of the preparation path.
    3/40
    N2017 / 01200 AT-00
    The first transfer device can in particular be designed in such a way that it can pick up bending tools stored in several levels of the storage device. At the transfer point, the bending tools are transferred from the first transfer device either directly or via a connection point to the turning device (this can be done, for example, using a manipulator of the first transfer device), or to an intermediate connection via which the bending tool subsequently reaches the turning device.
    The preparation path (also called the loading path) is used to load a connected bending press and / or (vice versa) to load the storage device with bending tools. The orientation of the preparation path is usually predetermined by the bending press or its tool holders and thus runs parallel to the bending line of the bending press. The provision path of the storage device can include a tool guide for holding and guiding bending tools. In the sense of the present application, the term “preparation path” is understood to mean a path via which bending tools can be moved away from the turning device (e.g. in the direction of a connected bending press) and / or (coming from the opposite direction) towards the turning device. The provision path in the sense of the present application can, but does not have to, form a complete connection between the turning device and a (to be connected) bending press. However, the provision path of the storage device can also form only a section of such a connection, or it can only be a connection point to which a further tool guide can be connected. The provision path can also be understood to mean a guide section which serves as a parking position for a movable transfer device for displacing the bending tools.
    The storage device preferably comprises a drive which interacts with the rotating device, in particular a motor, by means of which the rotating device can be driven. The drive can be controlled by a control device. The loading process can thus be automated.
    4/40
    N2017 / 01200 AT-00
    The storage locations for the bending tools are preferably stationary, i.e. arranged relative to or on the frame. The frame may be shelf-like, preferably with several shelf levels, e.g. in the form of a closet.
    The storage locations, the first transfer device, the rotating device and the preparation path can each have one or more tool guides in the form of guide rails, which run essentially horizontally, for holding and guiding bending tools. The bending tools are transferred from one tool guide to the other and are thus reliably held and guided throughout the transfer process. The tool guides preferably have a linear course.
    The bending tools for a bending press each have a shaped section for shaping a workpiece and a guide section for holding and guiding the bending tool in a tool guide. The guiding section therefore defines the guiding direction.
    The storage device is preferably designed to accommodate upper tools (hanging) and lower tools (standing).
    The storage device preferably comprises a rotating device for upper tools and a rotating device for lower tools, the rotating devices preferably being arranged one above the other. The axes of rotation of the rotating devices can coincide.
    The spacing between the storage locations provided in the storage device can vary depending on the type of tool, so that the highest possible packing density can be achieved. Larger distances between the individual storage locations will be provided for the storage of wider tools. With thinner tools, storage locations with a smaller distance are used. Storage locations can also be designed such that several (in particular identical) tools are stored in one storage location. If the storage space is replaced by a tool guide or
    5/40
    N2017 / 01200 AT-00
    Storage rail is formed, several tools can be arranged one behind the other.
    A preferred embodiment is characterized in that the rotary device has at least one (preferably linear) tool guide which can be rotated about a preferably vertical axis of rotation, which is in alignment with the preparation path in a first rotary position and points to the transfer point in a second rotary position, preferably the angle of rotation between the first rotational position and the second rotational position is at least 45 °, preferably at least 60 °. An aligned alignment is understood in particular to mean that a bending tool can be displaced from the tool guide of the rotary device by moving it along the tool guide into the tool guide of the preparation path.
    In this embodiment, the rotating device can be designed in the form of a turntable. The bending tool only has to be moved into the tool guide and then turned. The rotating device thus forms a link between the first transfer device and the preparation path.
    A preferred embodiment is characterized in that the rotating device has at least two (preferably linear) tool guides which can be rotated about the axis of rotation, the tool guides being inclined to one another, preferably by an angle of at least 60 °. The transfer of bending tools to the preparation path, in particular in a specific order, is made considerably easier and shortened in time by this measure. As a result, two bending tools can be held or rotated by the rotating device at the same time or moved relative to the rotating device. In this way, one bending tool can be moved from the first transfer device onto the rotating device, while at the same time another bending tool is moved from the rotating device onto the preparation path. The setup process of a bending press and thus the total cycle times are noticeably reduced.
    6/40
    N2017 / 01200 AT-00
    In one embodiment, the at least two tool guides intersect, preferably in the axis of rotation. This also enables a bending tool to be simply turned. For example, two tool guides could be inclined at 90 ° to each other.
    In another embodiment, the tool guides of the rotating device run without intersections; they are then radially spaced from the axis of rotation and can e.g. triangular or quadrangular. This means that there are no obstructions with multiple tools.
    A preferred embodiment is characterized in that the tool guides are arranged on a preferably disk-shaped platform which is rotatably mounted about the axis of rotation. The platform can e.g. be designed in the form of a circular disk or merely as a framework, carrier or frame that carries the tool guides.
    A preferred embodiment is characterized in that in at least one rotational position of the rotating device, a first tool guide of the rotating device is in alignment with the preparation path and a second tool guide of the rotating device points to the transfer point. This means that the turning device can be loaded on one side (transfer point) with a bending tool and at the same time unloaded on another side (preparation path).
    A preferred embodiment is characterized in that at least one tool guide of the rotating device can be pivoted relative to the platform about a pivot axis which is spaced from the axis of rotation and is parallel to the axis of rotation. For the loading process, the tool guide can be swung out in order to be aligned with the (tool guide of) the first transfer device at the transfer point. This extends the possibilities of loading the rotating device. Regardless of the number and arrangement of the tool guides of the rotating device, this can ensure that one tool guide is always aligned with the loading path and another tool guide is oriented for loading. Around
    7/40
    N2017 / 01200-AT-00 to reach the latter, too - if necessary - the relevant tool guide is swiveled about the swivel axis.
    The rotating device can have one or more drives by means of which the tool guide (s) can be pivoted relative to the platform. The drive can be controlled by a control device. The loading process can thus be automated.
    A preferred embodiment is characterized in that the pivoting movement of the at least one tool guide about the pivot axis is limited by a stop which is preferably formed on the platform. A certain orientation can be defined by the stop, in particular the orientation in which the tool guide is aligned with the first transfer device.
    A preferred embodiment is characterized in that the at least one tool guide of the rotating device passes between its first end and its second end a plane that is perpendicular to the longitudinal direction of the tool guide and contains the axis of rotation. The tool guide thus extends around the central plane. As a result, the rotating device can accommodate bending tools with the smallest space requirement. The diameter of a disk-shaped platform can therefore be kept very small. If the rotating device is formed by a disk-shaped platform, it is preferred if its diameter is at most 1.5 times the length of the tool guides of the storage locations.
    The first end and the second end of the at least one tool guide of the rotating device are preferably at the same distance from the axis of rotation. This measure also has a positive effect on the space requirement and the compactness of the rotating device.
    A preferred embodiment is characterized in that the at least one tool guide of the turning device at the point at which it turns 8/40
    N2017 / 01200-AT-00 axis comes closest, has a distance from the axis of rotation, the distance preferably being at least a quarter of the length of the tool guide. In this embodiment, the tool guides do not pass through the axis of rotation, but run decentrally. This prevents the tool guides from crossing and bending tools hindering one another. This measure also allows several, in particular three or four, tool guides to be provided on the rotating device with the smallest space requirement.
    A preferred embodiment is characterized in that the tool guides of the rotating device run along the sides of a preferably equilateral polygon, preferably an equilateral triangle or a square. The axis of rotation is at the center of the equilateral polygon. Such a symmetrical arrangement expands the possibilities of simultaneous loading / unloading of the rotating device.
    A preferred embodiment is characterized in that the storage locations each comprise a tool guide for holding and guiding at least one bending tool. The storage, like the transfer, can thus take place by means of tool guides, in particular guide rails, whereby the bending tool (with its guide section) is constantly held or shifted in a guide.
    A preferred embodiment is characterized in that the tool guides of the storage spaces are inclined to the tool guide of the supply path, preferably by an angle of at least 45 °, particularly preferably by an angle of at least 60 °, in particular by an angle of 60 ° or by one 90 ° angle. As already mentioned, this results in a particularly space-saving construction. The storage locations can be arranged one after the other along the direction of the provision path. The tool guides of the storage locations are arranged parallel to one another at least in groups.
    9/40
    N2017 / 01200 AT-00
    A preferred embodiment is characterized in that the at least one first transfer device for receiving a bending tool comprises a tool holder with which the storage locations and the transfer point can be approached. The tool holder serves to securely hold the bending tool during the process with the first transfer device. It is preferred if the tool holder can be moved in at least two spatial directions (horizontal and vertical) in order to be able to move to the storage locations arranged in several levels.
    A preferred embodiment is characterized in that the tool holder comprises a tool guide for holding and guiding at least one bending tool, wherein the tool guide of the tool holder can be brought into alignment with the tool guides of the storage locations. That the bending tools can be moved between the tool holder and the storage locations or also the rotating device (along the tool guide).
    A preferred embodiment is characterized in that the tool guide of the tool holder can be pivoted about a pivot axis parallel to the axis of rotation of the rotating device, preferably by an angle of at least 45 °, particularly preferably by an angle of at least 60 °, in particular by an angle of 60 ° , With a corresponding arrangement of tool guides on the turning device (e.g. with three tool guides that are each inclined at 60 ° to one another), at least two tool holders of the turning device can be loaded without having to rotate the latter in between. This therefore represents an advantageous extension of the maneuvering or set-up processes.
    A preferred embodiment is characterized in that the first transfer device has a manipulator which can be moved with the tool holder and by means of which a bending tool can be displaced into and / or out of the tool holder along the tool guide. The collection or storage of bending tools can be fully automated.
    10/40
    N2017 / 01200 AT-00
    A preferred embodiment is characterized in that the storage device has at least one second transfer device, by means of which a bending tool can be displaced along the tool guide of the preparation path. The loading or return process can thus take place independently of the first transfer device. The concept of the turning device represents a separation between the actual loading or return process along the supply path and the picking up or storing of the bending tools from or into the storage locations by the first transfer device. The first transfer device and the second transfer device work parallel. The rotating device represents a link between the first and second transfer device.
    The first transfer device and the second transfer device can be controlled independently of one another by a control device. The transfer device can therefore work in parallel in time.
    A preferred embodiment is characterized in that the second transfer device comprises a shuttle which can be moved along the tool guide, preferably in the tool guide of the preparation path, preferably in the form of a slide or carriage, the shuttle preferably having a releasable coupling for connecting a bending tool to the shuttle having. The shuttle can be connected to an elongated tension / pressure transmission means (in particular in the form of a chain, a rope or a band).
    A drive, which is preferably connected to a control device, acts on the retractable / extendable tension / pressure transmission means and thus moves the shuttle along the tool guide of the preparation path. Such a drive concept is also referred to as a pull / push actuator.
    An embodiment is therefore preferred in which the second transfer device has an extendable elongate (in particular flexible) tension and pressure transmission means, preferably in the form of a chain, a rope or a belt, which can be moved along the tool guide, preferably in the tool guide of the preparation path , In addition, a store, in particular a reel-up device or a store with spiral and / or meandering
    11/40
    N2017 / 01200-AT-00 extending guide, for holding the tension and pressure transmission means in the retracted state.
    A preferred embodiment is characterized in that storage locations of a first group of storage locations are formed by mutually parallel first tool guides and storage locations of a second group of tool guides by mutually parallel second tool guides, the first tool guides being inclined to the second tool guides, preferably by an angle of at least 45 °, particularly preferably by an angle of at least 60 °, in particular by an angle of 60 °.
    A preferred embodiment is characterized in that the rotating device is arranged between storage locations of the first group and storage locations of the second group. This means that the area around the rotating device can be optimally used for storage spaces.
    A preferred embodiment is characterized in that the rotating device is carried by the frame, the rotating device preferably being arranged in a shelf compartment of the frame. The rotating device is thus carried by the same frame on which the storage spaces are also formed. The storage device can be realized as a compact construction and combine all functions in itself (storage, provision in a desired order and orientation and loading of a bending press).
    A preferred embodiment is characterized in that the preparation path has a first guide section and a second guide section, at least part of the second transfer device being arranged in its retracted position in the first guide section and a bending tool along the second guide section consisting of and / or is displaceable in the storage device, and that at least a part of the rotating device is arranged between the first guide section and the second guide section of the preparation path. On the one hand, this creates a parking position for the second transfer device; on the other hand, the second Trans12 / 40
    N2017 / 01200-AT-00 can also be used to transfer a bending tool from the rotating device into the preparation path and (without changing the direction of movement) to load a bending press.
    A preferred embodiment is characterized in that the storage spaces are arranged in at least two levels, wherein preferably a plurality of storage spaces are arranged in a shelf compartment of the frame
    At least some of the storage locations are preferably arranged below and / or above the rotating device. These measures make the best possible use of the available space.
    A preferred embodiment is characterized in that the at least one first transfer device is arranged on a first side of the frame and the preparation path is arranged on a side of the frame opposite the first side, the rotating device forming a hatch between the opposite sides of the frame. This means that the transfer devices are not in the way and retain maximum freedom of movement.
    A preferred embodiment is characterized in that the first transfer device, the second transfer device and the rotating device each have at least one drive and / or actuator and can be controlled by a control device. This allows the individual actions of the various components to be coordinated with one another as best as possible. Specifically, the first transfer device and the second transfer device each have at least one traversing drive and the rotating device has a rotary drive (for rotating the tool guide about the axis of rotation).
    A preferred embodiment is characterized in that the memory device can be expanded in a modular manner and / or is formed from at least two memory modules releasably connected to one another, each of which has a large number of memory locations. This means that the storage capacity can be changed as required. For example, can offer a first memory module (which also includes the rotating device) with the corresponding memory capacity as basic equipment
    13/40
    N2017 / 01200 AT-00
    Tools are provided. A second memory module offers the possibility to expand the memory, e.g. for processing thick sheet and / or thin sheet and / or other types of workpieces. The memory size can be expanded as required by attaching or connecting additional memory modules.
    A preferred embodiment is characterized in that the storage device has at least one loading point accessible from outside the storage device, preferably via a loading hatch, for in particular manually loading the storage device with bending tools, the loading point preferably being accessible by the first transfer device and / or by at least a tool guide is formed. This enables an operator to store and retrieve tools during operation, i.e. the set-up or bending processes do not have to be interrupted in order to enable the use of new tools (not yet available in the storage device).
    The invention also relates to an arrangement comprising a bending press and at least one bending tool storage device connected to the bending press or its tool holder (s). It is preferred if a first storage device is connected to one side of the bending press and a second side is connected to the opposite side of the bending press. The storage devices are (indirectly) connected to one another via the tool holder (s) of the bending press. This means that the set-up and change processes can be carried out even faster.
    The object is also achieved by a method for loading a bending press with bending tools and / or for exchanging bending tools in a bending press, the bending press being connected to a bending tool storage device according to the invention, and that bending tools between the storage locations of the bending tool storage device and the tool holder the bending press by actuation of the first transfer device, actuation of the rotating device and displacement of the bending tools along the supply path to the bending press and / or be obtained by the bending press.
    14/40
    N2017 / 01200 AT-00
    A possible general procedure for changing tools is described in more detail below: the first transfer device takes a bending tool (by means of a manipulator) from the storage space and pushes it into the turning device (also called tool turning unit). The manipulator can e.g. comprise a magnetic and / or mechanical gripper and / or a suction gripper.
    The bending tool can now be turned in the rotating device or swiveled into the staging line (staging path) in a normal orientation. The second transfer device (also called bending line manipulator) then pushes the tool to the desired position in the tool holder of the bending press. By separating the second transfer device and the first transfer device, they can work independently of one another. While the second transfer device is still moving the tool, the first transfer device can already take another tool from a storage location and thus load the rotating device.
    The bending tool storage device can have the same components for upper tools and lower tools: storage locations, first transfer devices, rotating devices and second transfer devices. The upper and lower tools are stored and loaded independently of one another according to the principle described above.
    In a rack storage version, the lower tools are each in tool guides and the upper tools are each suspended in tool guides. Several tools can be stored according to type in the tool guide of a storage location. In order to increase the storage capacity, the shelf can be stretched in length or built higher. The height and side distances of the storage rails are adjusted according to the tool to be stored.
    The rotating device represents the connecting link between the first and second transfer device. The tool is inserted into the rotating device,
    15/40
    N2017 / 01200-AT-00 or retracted and optionally pivoted to the bending line by turning left or right. The orientation (turning of the tool) can be defined based on the direction of rotation. The second transfer device can be designed such that it pushes the tool through the turning device into the tool holder of the bending press or (in the opposite direction) pulls the tool out of the bending press into the turning device.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    For the sake of order, it should finally be pointed out that, for a better understanding of the structure, elements have sometimes been shown to scale and / or enlarged and / or reduced.
    1, 2 and 3 show a bending tool storage device 1 for storing bending tools 2. A multiplicity of storage locations 4 with bending tools 2 (here: upper and lower tools) are arranged on a shelf-like frame 3.
    The sub-tool-related components of the storage device 1 are explained in more detail below. The upper tool-related components work on the same principle, except that the upper tools are transported hanging (and not standing) and stored.
    FIG. 2 shows a preparation path 10 in the form of a tool guide 11, along which the bending tools 2 are output and brought in.
    On the opposite side (FIG. 1), a first transfer device for transferring bending tools 2 is arranged between the storage locations 4 and a transfer point 6.
    Between the transfer point 6 and the preparation path 10, the storage device has a rotating device 7 for rotating the bending tools 2. The rotating device represents a link between the first transfer device 5 and a second transfer device 20 (described in detail below).
    The rotating device 7 has at least one tool guide 9 which can be rotated about a preferably vertical axis of rotation 8, which is in a first rotational position in alignment with the preparation path 10 and in a second rotational position facing the transfer point 6 (see FIGS. 1 and 10). The angle of rotation between the first rotational position and the second rotational position is preferably at least 45 °, preferably at least 60 ° (see also the variants according to FIGS. 4, 5 and 8, in which this angle of rotation is 90 ° or 120 °).
    18/40
    N2017 / 01200 AT-00
    It is preferred if the rotating device 7 has at least two tool guides 9 rotatable about the axis of rotation 8, the tool guides 9 being inclined to one another, preferably by an angle of at least 60 °. An embodiment with two tool guides 9 is shown in FIG. 5, with three tool guides 9 in FIGS. 7 and 8 and with four tool guides 9 in FIG. 4.
    The tool guides 9 of the rotating device 7 are arranged on a disk-shaped platform 17 which is rotatably mounted about the axis of rotation 8.
    In at least one rotational position of the rotating device, a first tool guide 9 of the rotating device 7 is in alignment with the preparation path 10 and has a second tool guide 9 of the rotating device 7 to the transfer point 6.
    7 shows a special embodiment in which the tool guides 9 of the rotating device 7 can be pivoted relative to the platform 17 about pivot axes 19 which are spaced from the axis of rotation 8 and are parallel to the axis of rotation 8. As a result, as shown in FIG. 6, the bending tool can be transferred to the rotating device at two positions or unloaded from the rotating device, thereby expanding the possibilities for loading and storing processes. In particular, the transfer device 5 can transfer a bending tool to a tool guide 9 of the turning device 7, then move to the second position and there take another bending tool from the turning device 7 from another tool guide 9 and bring it to a storage location 4.
    The pivoting movement of the tool guides 9 about the pivot axis 19 can be limited by a stop 18 preferably formed on the platform 17. A drive (not shown) can be controlled by a control device in order to effect this pivoting movement about the pivot axis 19.
    The tool guides of the rotating device 7 are designed such that each tool guide has one between its first end and its second end
    19/40
    N2017 / 01200 AT-00
    Plane that is perpendicular to the longitudinal direction of the respective tool guide and contains the axis of rotation 8 passes. The first end and the second end of the respective tool guides 9 of the rotating device 7 have essentially the same distance from the axis of rotation 8 in all the illustrated embodiments.
    While the tool guides 9 cross in FIG. 5, the tool guides 9 in FIGS. 4 and 8 are arranged without crossings. At the point where they come closest to the axis of rotation 8, they are at a distance A from the axis of rotation 8, the distance A preferably being at least a quarter of the length of the tool guide 9.
    It is particularly preferred if the tool guides 9 of the rotating device 7 run along the sides of a preferably equilateral polygon, preferably an equilateral triangle or a square.
    The storage locations 4 and the first transfer device 5 are described in more detail below:
    The storage locations 4 each comprise a tool guide 14 for holding and guiding at least one bending tool 2 (FIGS. 1.6 and 9).
    The tool guides 14 of the storage locations 4 are inclined to the tool guide 11 of the preparation path 10, preferably by an angle of at least 45 °, particularly preferably by an angle of at least 60 °. In Fig. 1 this angle is 90 °, in Fig. 6 this angle is 60 °.
    The first transfer device 5 for receiving a bending tool 2 comprises a tool holder 15 with which the storage locations 4 and the transfer point 6 can be approached. The tool holder 15 comprises a tool guide 16 for holding and guiding at least one bending tool 2. The tool guide 16 of the tool holder 15 can be brought into alignment with the tool guides of the storage locations 4, so that a bending tool 2 can be shifted from an approached storage location 4 into the tool holder ,
    20/40
    N2017 / 01200 AT-00
    In the particular embodiment of FIG. 9, the tool guide 16 of the tool holder 15 can be pivoted about a pivot axis 13 parallel to the axis of rotation 8 of the rotating device 7 (here by an angle of at least 60 °).
    As a result, two tool guides 9 can be loaded into the rotating device 7 (see the two arrows inclined by 60 ° in FIG. 9) without having to rotate the rotating device 7.
    The first transfer device 5 can have a manipulator 12 which can be moved with the tool holder 15 (shown schematically in FIGS. 1 and 8), by means of which a bending tool 2 can be displaced along the tool guide 14, 16 into and / or out of the tool holder 15.
    The storage device 1 also has a second transfer device 20, by means of which a bending tool 2 can be displaced along the tool guide 11 of the preparation path 10 (FIGS. 2 and 3).
    The second transfer device 20 can comprise a shuttle 21, preferably in the form of a carriage or carriage, which can be moved along the tool guide 11, preferably in the tool guide 11 of the preparation path 10. The shuttle 21 can have a releasable (e.g. mechanical, magnetic or suction) coupling for connecting a bending tool 2 to the shuttle 21. The shuttle 21 can be moved in a self-propelled manner or by means of an elongated pull / pressure transmission means (in particular a chain) (not shown). The tension / pressure transmission means can also be movable in the tool guide 11 of the preparation path 10.
    If - as shown in FIG. 9 - storage locations 4 of a first group 22 of storage locations are formed by mutually parallel first tool guides 14 and storage locations of a second group 23 of tool guides are formed by mutually parallel second tool guides 24, the first tool guides 14 forming the second tool guides 24 are inclined (here by an angle of 60 °), the available space can be optimally used. This is particularly the case when the rotating device 7 between
    21/40
    N2017 / 01200 AT-00
    Storage locations 4 of the first group 22 and storage locations 4 of the second group 23 are arranged.
    From Fig. 1 it can also be seen that the rotating device 7 is carried by the frame 3 and is arranged in a shelf compartment of the frame 3.
    The preparation path 10 can have a first guide section 25 and a second guide section 26, at least part of the second transfer device 20 (here the shuttle 21) being arranged in its retracted position in the first guide section 25 and a bending tool 2 along the second guide section 26 can be moved out of and / or into the storage device 1. At least a section of the rotating device 7 is arranged between the first guide section 25 and the second guide section 26 of the preparation path 10 (see, for example, FIG. 4).
    As can be seen from FIG. 1, the storage spaces 4 are arranged in at least two levels, wherein a plurality of storage spaces 4 can be arranged in a shelf compartment of the frame 3. In the embodiment shown, at least some of the storage locations 4 are arranged below and / or above the rotating device 7.
    A preferred aspect is also that the at least one first transfer device 5 is arranged on a first side of the frame 3 (FIG. 1) and the preparation path 10 is arranged on a side of the frame 3 (FIG. 2) opposite the first side. The rotating device 7 forms a hatch between the opposite sides of the frame 3.
    3 shows an arrangement of a bending press 27 and a bending tool storage device 1 connected to the bending press. In a method for loading a bending press 27 with bending tools 2 and / or for exchanging bending tools 2 into the bending press 27, bending tools 2 become between the storage locations 4 of the bending tool storage device 1 and the tool holder 28 of the bending press 27 by actuation
    22/40
    N2017 / 01200-AT-00 of the first transfer device 5, actuation of the rotating device 7 and displacement of the bending tools 2 along the preparation path 10 (by means of a second transfer device 20) are output to the bending press 27 and / or obtained from the bending press 27.
    A great advantage can be seen in the fact that the first and second transfer devices can work independently of one another, as a result of which the cycle times in the production of workpieces can be significantly reduced.
    3 shows only one storage device 1 connected to the bending press 27, in an expanded embodiment two storage devices could be connected to the bending press. It is preferred if a first storage device is connected to one side of the bending press (see FIG. 3) and a second storage device to the opposite side of the bending press. By providing two storage devices, the setup and change processes can be shortened further.
    11 shows a memory device 1 which can be expanded in a modular manner or is formed from at least two memory modules 30, 31 detachably connected to one another, each of which has a large number of memory locations 4. The rotating device 7 can be accommodated in the first memory module 30, while the second memory module 31 can only accommodate memory locations 4. The first transfer device 5 (not shown in FIG. 11) can be designed such that it can move to the memory locations of the first and second memory modules.
    Fig. 11 also shows one from outside the storage device 1, e.g. Via a loading hatch, accessible loading point 29 for, in particular, manual loading of the storage device 1 with bending tools 2 (upper and lower tools for this). The loading point 29 can be approached by the first transfer device 5 and is preferably formed by at least one tool guide. In this way, the bending tools that are placed in the loading point can be picked up by the first transfer device in the same way as the bending tools 23/40
    N2017 / 01200-AT-00 witnesses, which are arranged in the memory locations. The tool guide of the loading point 29 is preferably parallel to the tool guides of the storage locations 4.
    12 finally shows the second transfer device 20. A shuttle 21 can be moved along the tool guide 11, here even in the tool guide 11 of the preparation path 10 or (in the further course) in the tool holder 28 of a connected bending press 27 (see FIG. 3) , The shuttle 21 is pushed or pulled by an elongated pull / pressure transmission means 32. The transmission means 32 is preferably formed from chain links. The tension and pressure transmission means 32 can be moved along the tool guide 11, here in the tool guide 11 of the preparation path 10 or (in the further course) in the tool holder 28 of a connected bending press 27 (see FIG. 3).
    In conclusion, it should be pointed out that the components, in particular the first transfer device, the second transfer device and the rotating device, can be controllable by a control device. The interaction between these components can be optimized.
