    The invention relates to a bending tool storage for storing bending tools with a plurality of guide rails for holding and guiding of bending tools. The invention also relates to a bending tool storage device and a method for depositing at least one bending tool into a tool storage and / or for removing at least one bending tool from a tool storage.
    CH668035A5 discloses a bending press and a mechanism for changing bending tools. Bending tools are suspended in a storage device each on a hook. The change takes place by means of a support arm rotatable about a horizontal pivot axis, which receives a single bending tool and transfers it from the tool store into the bending press. A disadvantage of this changing device is that much space must be provided for the movement of the support arm. In addition, the approach and pivoting of the arm in the direction of the tool holder of the bending press requires a complex sequence of movements. In addition, there is a high risk of collision between the support arm and parts of the bending press on the one hand and the tool storage on the other. A large amount of time when changing is also due to the fact that the bending tools only individually, i. can be transferred one after the other.
    EP2143506B1 discloses a device for exchanging and assembling a multi-part tool for a press brake. A complex and space-demanding transfer device with a gripper or hook removes bending tools from the tool storage and spends them in the bending press. The
    Transfer device is vertically and horizontally movable for this purpose; The Ha ken additionally rotatable.
    Other known from the prior art memory devices have the disadvantage that their storage capacity is very low. That the number of bending tools that can be stored per unit of space in the storage device is limited or collisions between individual bending tools can not be ruled out.
    The resulting from the prior art disadvantages therefore exist on the one hand in the complex and space-demanding design of the tool storage and the transfer device, which transfers the bending tools from the tool storage in the bending press. On the other hand, the storage capacity of the tool memory is very limited or requires such tool memory very much space. This results in particular from the fact that (as in CH668035A5) a separate holding structure, e.g. in the form of a hook, is required or that (as in both references mentioned above) the tool memory must have sufficient (intermediate) space for the retraction of the transfer device. Changing tools can be time-consuming. In addition to an increased risk of collision of the moving parts, including the bending tools and the transfer device, the expense is a disadvantageous factor of known devices.
    The object of the invention is to eliminate these disadvantages and to provide a bending tool storage which can be dimensioned space-saving and which has a higher storage density, i. can accommodate a higher number of bending tools per room unit. The loading and changing of bending tools should be accomplished in a simple and reliable way. The bending tool storage and its Be-operation should be cheaper.
    This object is achieved with a bending tool storage of the type mentioned by at least a first portion in which the angular distances between adjacent guide rails are each at most as large as a first angle, and at least a second portion in which the angular distances between adjacent guide rails respectively at least are large as a second angle, wherein the second angle is greater than the first angle.
    By this measure, an increase in the storage density is achieved. In the first section, more guide rails are arranged per angular unit (than in the second section) and accordingly more bending tools can be accommodated. Above all, by the solution according to the invention the fact can be taken into account that bending tools have different size and shape. Thus, the first section can be used specifically to accommodate shorter and / or narrower bending tools. On the other hand, longer and / or wider bending tools can be accommodated in the second section. With an appropriate memory strategy, the achievable storage density, ie the number of bending tools per unit of space, can thereby be increased.
    The angular distance is to be understood as that angle by which the adjacent guide rails are inclined relative to one another. The guide rails can be distributed over the entire circumference of the bending tool memory.
    The guide rails are each spaced apart by angular distances from each other; the guide rails each extend in a direction from inside to outside.
    In the case of an annular or partially annular tool storage, the guide rails extend from the inner circumference in the direction of the outer circumference of the tool storage. In the case of a disc-shaped (inner) tool storage from an inner area in the direction of the exterior. The directions in which the guide rails run, thus each have a radial component.
    In one embodiment, the guide rails of the outer tool store and the guide rails of the at least one inner tool store each extend in the radial direction (the course direction of the guide rails here has no tangential component) or in a direction with a radial component.
    In an alternative embodiment, the guide rails each extend in directions with tangential component. The guide rails extend in this embodiment from the inside outwards, but inclined to the (pure) radial direction Rich. The length of the individual guide rails can be increased by this measure. In this embodiment, the extending directions of the guide rails have a tangential component in addition to a radial component. The radial or tangential direction component is in each case based on the ring, Teilring-, or disc shape (or the mid-point) of the respective tool memory.
    The radial direction or the radial direction component of the guide rails in each case refers to a center which can be defined by a ring shape, part ring shape or disk shape (or circular shape) of the bending tool memory. Due to the course of the individual guide rails respectively in the radial direction and in a radial component direction, the distance between adjacent guide rails of a tool storage increases in the radial direction (i.e., from the inner periphery toward the outer periphery of the bending tool storage). That adjacent guide rails are at an angular distance from each other (or are not parallel to each other).
    In the first section, the bending tool storage has a higher density of guide rails (smaller angular distance) and in a second section a lower density of guide rails (larger angular distance). The tool storage thus has along its circumference on the first portion in which the angular distance between adjacent guide rails is smaller than in the second portion along its circumference.
    It should be noted that the bending tool storage may also have two or more first and / or second sections, which may be e.g. alternate along the circumference.
    Adjacent guide rails of the first section may be spaced from each other such that in the region of the outer circumference (short) bending tools can be placed side by side (i.e., in adjacent guide rails) without touching each other. In the area of the inner circumference, on the other hand, the lateral spacing between adjacent guide rails could already be so small that it comes into contact when two bending tools are simultaneously pushed through this area. The advantage of being able to accommodate more bending tools next to each other in guide rails, however, outweighs.
    A preferred embodiment is characterized in that in the first section, the angular distances between adjacent guide rails are each as large as the first angle and / or that in the second section, the angular distances between adjacent guide rails are each as large as the second angle. As a result, an arrangement of essentially equidistant (i.e., the same angular distance from each other) guide rails can be achieved in the first and / or second section.
    A preferred embodiment is characterized in that the second angle is at least 1.3 times, preferably at least 1.5 times, more preferably at least 2 times, as large as the first angle. The packing density in the first section, ie the number of bending tools to be stored per room unit, can thus be increased by the corresponding factor.
    A preferred embodiment is characterized in that the bending tool storage is rotatable, in particular about an axis of rotation passing through the center point defined by the radially extending guide rails. Thereby, each guide rail can be moved into a working area, e.g. a transfer device be moved.
    A preferred embodiment is characterized in that the bending tool storage is annular, semi-annular or disc-shaped. This makes possible an arrangement which can form an efficient storage device in cooperation with a bending tool transfer device and / or further, in particular concentrically arranged bending tool stores.
    A preferred embodiment is characterized in that the at least one first section and / or the at least one second section extend over an angular range of at least 30 °, preferably at least 60 °, particularly preferably at least 90 °. As a result, a substantial increase in the storage density can be achieved.
    A preferred embodiment is characterized in that the first section and / or the second section comprise at least 3, preferably at least 5, particularly preferably at least 10, guide rails.
    A preferred embodiment is characterized in that shorter bending tools are held in guide rails of the first section than in guide rails of the second section, wherein the bending tools are closer to the radial direction than the outer ends of the guide rails closer than the inner ends, preferably are arranged in the region of the outer ends of the guide rails. Such a storage strategy takes into account the size and shape of the bending tools, thereby increasing the achievable storage density.
    A preferred embodiment is characterized in that in the first section, the distance between the longitudinal axes of adjacent guide rails in the region of their - related to the radial direction - inner ends at least as large, preferably smaller than the dimension of a in one Guide rail of the first section held bending tool perpendicular to the direction of the guide rail. The available space is thereby optimally utilized, in which the guide rails are arranged as close to each other as possible.
    Another embodiment of the invention, which can also manage without the first and second sections, is based on the idea that the guide rails are so close to each other, i. Such a small angular distance aufwei-sen each other, that it could also lead to collisions between bending tools. This is prevented, however, by (a) positioning the short bending tools, radially outwardly, where the distance between the guide rails is greater than the inside, and (b) the long bending tools occupy at most only every other guide rail, so that it no collision can occur. The storage specifications (a) and (b) can also be combined so that a short bending tool is accommodated in each case between long bending tools. This embodiment is characterized in that the angular distances between adjacent guide rails are dimensioned such that the distance between the longitudinal axes of adjacent guide rails in the region of their - related to the radial direction - inner ends at most as large, preferably smaller than, is the dimension of a bending tool held in a guide rail perpendicular to the direction of the guide rail. As with the other embodiments, there is also the common idea of increasing storage capacity.
    The object of the invention is also achieved with a bending tool storage device for storing bending tools, comprising at least one storage unit comprising an outer tool storage which is ring-shaped or semi-annular and a plurality of (eg in the radial direction or in a tangential direction Component running) guide rails for holding and guiding of bending tools, wherein the storage unit comprises at least one inner tool storage disposed within the outer tool storage and having a plurality of radially extending guide rails for holding and guiding of bending tools, and that the outer tool storage and the inner tool storage are rotatable relative to each other, wherein at least one guide rail of the outer tool storage in different relative rotational positions between-ßerem tool storage and inner tool storage each with a the Fiihrungsschiene of the inner tool storage is in alignment, and that the inner tool storage and / or the outer tool storage according to the invention is / are formed.
    By providing at least one inner tool storage, on the one hand, the storage capacity of the storage device is increased, and on the other hand, the storage and extraction of individual bending tools into or out of the tool stores is simplified. The counter-rotation of the tool train storage allows complex maneuvering operations, in which the bending tools are moved along the guide rails.
    The outer tool storage and the at least one inner Werkzeugspei-cher are in a common plane (or can be brought into a common plane), so that a bending tool can be moved from a tool storage in the other tool storage.
    With the storage or charging device according to the invention, it is also possible to accommodate several bending tools in a guide rail in a row behind one another, whereby the storage density of the tool storage is further increased. In order to extract or separate a first bending tool from this row, bending tools can be temporarily moved into the respective other tool storage and stored there (between). In addition, the two mutually rotatable tool storage allow bending tools from one (or a first) guide rail of the tool storage in another (or second) guide rail of the same tool storage can be moved. Such shunting operations take place exclusively by shifting operations of bending tools along guide rails and relative rotation (s) between the tool stores.
    An advantage of this embodiment is that the bending tools remain uninterrupted in guide rails during the maneuvering maneuver (i.e., do not have to be removed from the guide rails). The transfer of a bending tool from a guide rail (eg, the outer tool storage) into another guide rail (eg, the inner tool storage) is accomplished by aligning the two guide rails (to form a continuous guide section) and displacing the bending tool from one guide rail to the other guide rail. Intermediate steps, which include the removal of a bending tool from a guide rail and reinserting, are not required due to the principle according to the invention.
    In order to realize a relative movement (rotation) between the outer and inner tool storage, it is possible to form the outer tool storage and / or the inner tool storage rotatably. Due to the relative rotation, the guide rail (s) of one tool store can be aligned with different guide rails of the other tool store.
    By this measure, on the one hand the charging process can be accelerated and made more efficient, on the other hand increases the possible storage density of bending tools in the storage device.
    The outer tool store and / or the inner tool store can each form a closed ring (annular) or a ring open on one side (partially annular). With respect to storage density, annular tool stores (closed ring) are preferred, but for other reasons (e.g., space), semi-annular tool stores may be used. The inner tool storage could be formed instead of a ring shape in the form of a disc.
    A preferred embodiment is characterized in that the at least one inner tool storage is arranged concentrically to the outer tool storage. The center points, which are defined by the ring shape, partial ring shape or disc shape of the tool stores, coincide. This allows not only a space-saving arrangement but also an increase in storage density. It is also possible to rotate the tool storage around a common axis of rotation.
    A preferred embodiment is characterized in that the inner diameter of the outer tool storage substantially corresponds to the outer diameter of the inner tool storage. At best, there is a small gap between the tool stores so that the bending tools can be moved directly from one tool store to the other.
    A preferred embodiment is characterized in that the outer tool storage and the at least one inner tool storage are rotatable, preferably about a common axis of rotation. The fact that both tool stores are rotatable by themselves (particularly relative to a frame on which both tool stores are stored) increases the options for maneuvering operations, thereby simplifying and shortening the loading process.
    Preferably, the outer tool storage and the inner tool storage of the storage unit each have their own rotary drive. This allows the tool stores to be rotated simultaneously and independently.
    In an alternative embodiment, at least two tool memories of the memory unit have a common rotary drive, from which they can be individually coupled off. In this embodiment, at least one rotary drive can be saved. An actuatable clutch provides for the coupling or uncoupling of the tool storage of the rotary drive.
    A preferred embodiment is characterized in that the storage unit comprises at least one sensor, in particular an angle sensor, for determining the rotational position of the outer tool storage and / or of the at least one inner tool storage. This allows automation of storage and loading operations.
    A preferred embodiment is characterized in that a transfer device for moving the bending tools along the Fiihrungsschienen is disposed within the inner tool storage.
    A preferred embodiment is characterized in that the storage unit comprises at least two inner tool storage, which are rotatable relative to each other. This can further increase the storage capacity. Also, the other (s) inner tool storage (s) from the inside outwardly extending Fiihrungsschienen that can get into alignment alignment by relative rotation with guide rails of the adjacent tool storage. A storage unit may also include a plurality of concentrically arranged (partially) annular tool stores.
    A preferred embodiment is characterized in that the storage device has at least two storage units, which are arranged one above the other and preferably concentric with each other. This can create a bending tool reservoir with large storage capacity.
    A preferred embodiment is characterized in that the guide rails of a first storage unit and the guide rails of a second storage unit are facing each other. The first storage unit thus represents a lower tool storage and the second storage unit is an upper tool storage. The upper tool and lower tool units are preferably arranged one above the other (and according to the arrangement of the tool holders in a bending press).
    A preferred embodiment is characterized in that the storage device comprises at least one clipboard, which has at least one guide rail for holding and guiding bending tools, wherein the clipboard can be moved between the storage units. As a result, a bending press from various storage units with bending tools be sent.
    The object is also achieved with a feeding device, in particular changing device, for feeding a bending press with bending tools and / or for replacing one or more bending tools used in a bending press, comprising a storage device according to the invention. The loading device may comprise a transfer device for moving bending tools along guide rails.
    A preferred embodiment is characterized in that the transfer device comprises a shuttle, which can be moved along the guide rail (s) and is preferably guided in the guide rail, in particular in the form of a carriage or carriage.
    A preferred embodiment is characterized in that the transfer device comprises an elongate, preferably flexible tensile and / or pressure transfer means, in particular a band, a rope, a rod or a chain, and that the shuttle to the Zug- and / or pressure transmission means is connected. By using a tension and / or pressure transmission means, the traverse drive of the transfer device can be arranged far away from the guide rails. The transfer device can thereby also be designed low-weight and space-saving. The transmission means can be designed to transmit tensile forces or compressive forces or tensile and compressive forces. If the feeding or changing of the bending tools takes place only from one end of the rail, a tension and pressure transmission means is used.
    The transfer device, in particular the shuttle, preferably has a releasable coupling for connecting a bending tool. This allows the transfer device not only push the bending tools, but also pull. The clutch has a releasing (released) position and a coupling position and can be actuated by an actuator. The coupling may e.g. be designed as a mechanical clutch, magnetic coupling or as a suction device. The coupling can produce a frictional and / or positive connection with the bending tool. The actuator for actuating the clutch may comprise a cylinder-piston unit, a linear drive, a motor, a sub-pressure device and / or an electromagnetic device.
    In an alternative variant, the shuttle could also be designed to be self-propelled, wherein the travel drive is arranged in or on the shuttle. The transfer device can be constructed in this way particularly component-saving. The control of the shuttle could be wired, but also by radio.
    The object is also achieved with an arrangement of a bending press and a coupled therewith feeding device according to the present invention for feeding the bending press with bending tools, wherein the bending press has a guide rail designed as tool holder for holding and guiding of bending tools. The bending press and the loading device can form a continuous guide section, so that a bending tool can only be transferred from or into the bending press by displacement along guide rails.
    The object is also achieved with a method for depositing at least one bending tool in a tool storage and / or for removing at least one bending tool from a tool storage, in particular for Ver bring the bending tool from Or into a bending press, wherein the tool storage is designed according to the invention and wherein the at least one bending tool is verscho ben along a guide rail of the tool storage.
    A preferred embodiment is characterized in that shorter bending tools are stored in guide rails of the first section than in guide rails of the second section.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    Fig. 3 shows a bending tool memory 4 for storing bending tools 2 with a plurality of radially extending guide rails 14 for holding and guiding of bending tools 2. The bending tool memory has a first portion 11, in which the angular distances a between adjacent guide rails 14 each at most are large as a first angle, and a second-th portion 12 in which the angular distances ß between adjacent guide rails 14 are each at least as large as a second angle, wherein the second angle is greater than the first angle.
    In the illustrated embodiment, the angular distances in the respective sections 11, 12 are substantially constant. That in the first section 11, the angular spacings a between adjacent guide rails 14 are each as large as the first angle, and in the second section 12, the angle spacings β between adjacent guide rails 14 are each as large as the second angle.
    In a preferred embodiment, the second angle may be at least 1.3 times, preferably at least 1.5 times, more preferably at least 2 times, as large as the first angle.
    The bending tool storage 4 of FIG. 3 is annular, but could be formed in an alternative embodiment, but also part-ring-shaped or disc-shaped.
    The first section 11 and the second section 12 extend over an angular range of at least 30 °, preferably at least 60 °, particularly preferably at least 90 °, along the circumference of the bending tool store 4.
    It is also preferred if the first section 11 and the second section 12 each comprise at least 3, preferably at least 5, particularly preferably at least 10, guide rails 14.
    From FIG. 3 it can be seen that shorter bending tools 2 are held in guide rails 14 of the first section 11 than in guide rails 14 of the second section 12, wherein the bending tools 2 in the guide rails 14 of the first section 11 outer ends of the guide rails 14 are closer than the inner ends. In Fig. 3, they are arranged in the region of the outer ends of the guide rails 14.
    It can also be seen from FIG. 3 that in the first section 11, the distance between the longitudinal axes 10 of adjacent guide rails 14 in the region of their inner ends, which are relative to the radial direction, is at most as large (preferably even smaller) than the dimension of a held in a guide rail 14 of the first section 11 bending tool 2 perpendicular to the direction of the guide rail fourteenth
    FIGS. 1, 2 and 5 show embodiments of how a bending tool storage device according to the invention can be integrated in a storage unit 3 of a bending tool storage device 1. It should be noted at this point that the embodiments according to FIGS. 4 and 7 also comprise at least one bending tool storage according to the invention, e.g. in type of Fig. 3, may contain.
    1 shows a bending tool storage device 1 for storing bending tools 2. A storage unit 3 of the storage device 1 comprises an outer (bending) tool storage 4 which is annular (alternatively: part-annular) and a plurality of radially extending guide rails 14 for holding and guiding bending tools 2 has. The outer Werkzeugspei-cher 4 is formed as shown in Fig. 3.
    The storage unit 3 comprises an inner (bending) tool storage 5, which is disposed within the outer tool storage 4 and also has a plurality of radially extending Fiihrungsschienen 15 for holding and guiding of bending tools 2. The outer tool storage 4 and the inner tool storage 5 are rotatable relative to each other, wherein at least one Fiihrungsschiene 14 of the outer tool storage 4 in different relative rotational positions between the outer tool storage 4 and inner
    Tool memory 5 is in each case in alignment with another guide rail 15 of the inner tool storage 5.
    The inner tool storage 5 is also annular (alternatively: partial ring-shaped). The tool storage 4, 5 are arranged concentrically with each other and rotatable about a common axis of rotation 18.
    As shown in FIG. 2, the inner tool storage 5 can also be designed according to the invention. In a first section (which is positioned in the same angular range in FIG. 2 as the first section 11 of the outer bending tool storage 4), the inner tool storage 5 has a higher density of guide rails 15 (smaller angular distance) and in a second Section a lower density of guide rails 15 (larger angular distance) on.
    Within the inner tool storage 5, a transfer device 9 for moving the bending tools 2 along the guide rails 14,15 is arranged. The transfer device (which is shown in detail in FIG. 6) can comprise a shuttle 22 which can be moved along the guide rail (s) and is preferably guided in the guide rail, in particular in the form of a carriage or carriage.
    Likewise, the transfer device 9 may comprise an elongate, preferably flexible, tensile and / or pressure-transmitting means 23, in particular a band, a rope, a rod or a chain. The shuttle 22 is connected to the tension and / or pressure transmission means 23. The transfer device 9, in particular the shuttle 22, preferably has a releasable coupling for connecting a bending tool 2. This allows the transfer device not only push the bending tools, but also pull.
    The inner diameter of the outer tool storage 4 corresponds substantially to the outer diameter of the inner tool storage. As can be seen from the preferred embodiment of FIG. 1, the outer tool storage 4 and the inner tool storage 5 each form a closed ring
    From Fig. 1 it can be seen that the number of guide rails 14 of the outer tool storage 4 is larger (in this case: twice as large) than the number of guide rails 15 of the inner tool storage 5. Thus, the angle is also between adjacent guide rails 14 of the outer tool storage 4 smaller (here: 9 ° in the second section 12) than the angular distance between adjacent guide rails 15 of the inner tool storage 5 (here: 18 °). Of course, Figs. 1 and 2 are to be understood as illustrative examples, and is any possible distribution of radially extending or a radial direction component having guide rails possible.
    FIG. 2 shows an application in which shorter bending tools 2 are held in the guide rails 14 of the outer tool storage 4 than in the guide rails 15 of the inner tool storage 5.
    FIG. 7 shows that the outer tool storage 4 and the inner tool storage 5 of the storage unit 3 can each have their own rotary drive 19. These are - as well as the drive of the transfer device - controlled by a control device 24.
    In an alternative embodiment, at least two tool stores of the storage unit 3 can have a common rotary drive from which they can be individually decoupled (by means of a coupling, for example a coupling ring).
    The storage unit 3 preferably comprises at least one sensor 8 (see FIG. 7), in particular an angle sensor, for determining the rotational position of the outer tool storage 4 and / or the at least one inner tool storage 5.
    5 shows a storage device 1, in which the storage unit 3 comprises at least two inner tool stores 5, 6, which are rotatable relative to one another.
    4 shows an embodiment with a plurality of storage units 3, 13, which are arranged one above the other and (also here) concentrically with one another.
    The guide rails of the tool storage of a first storage unit and the guide rails of the tool storage of a second storage unit are facing each other (see lower part and upper part of Fig. 4).
    Also visible is a clipboard 7, which has a guide rail 17 for holding and guiding bending tools 2. The clipboard 7 is movable between the storage units 3, 13 (here: along the double arrow). It is preferred if the clipboard 7 is also rotatable about a rotation axis 28. As a result, the orientation of a bending tool or a series of successively arranged bending tools (by 180 °) can be changed. The assembly of the bending tools and the loading of the bending press are thereby extended by a further option.
    The object shown in the left part of FIG. 7 represents a loading device, in particular a changing device, for loading a bending press 20 with bending tools 2 and / or for exchanging one or several other bending tools 2 used in a bending press 20 Tool holders 21 of the bending press are simultaneously guide rails along which the bending tools are moved to their desired position.
    A method for depositing at least one bending tool 2 into a tool store 4 and / or for removing at least one bending tool 2 from a tool store 4, in particular for transferring the bending tool 2 from or into a bending press 20, can now be carried out with the bending tool store, wherein at least one Bending tool 2 is moved along a Fiih-rungsschiene 14 of the tool storage.
    In the case of several bending tool stores, the at least one bending tool 2 is displaced along guide rails 14, 15, 16 of the tool stores 4, 5, 6.
    The method is performed with a maneuvering process in which at least one bending tool 2 is displaced from a guide rail 14, 15 of a tool store 4, 5 into a guide rail 15, 14 of the other tool store 5, 4 (FIG. 2) and in which a tool store 4, 5 and the other tool memory 5, 4 are rotated relative to each other.
    As can be seen from FIG. 2, it may be preferred if four bending tools 2 are deposited in the guide rails 14 of the outer tool store 4 than in the guide rails 15 of the inner tool store 5.
    In a storage device 1 according to FIG. 3, it is preferred if in the guide rails of the first section 11 shorter bending tools 2 are deposited than in the guide rails of the second section 12.
    8 shows an alternative embodiment of a bending tool storage device 1 for storing bending tools 2. A storage unit 3 of the bending tool storage device 1 includes an outer tool storage 4 and an inner tool storage 5 having a plurality of guide rails 14, 15. The tool storage 4, 5 may be annular (alternatively: partial ring-shaped) may be formed. The guide rails 14,15 extend in directions 26, which - based on the ring shape or partial ring shape of the respective tool storage - have a tangential component. The guide rails 14,15 are also in this embodiment from the inside out or from the inner periphery to the outer periphery of the tool storage. They thus have - based on the ring shape or partial ring shape of the respective tool storage - (in addition to the tangential component) and a radial component. Based on an (imaginary) circle circumference 25, which is concentric with the outer tool storage 4 and the inner tool storage 5, the guide rails (tangentially) run tangentially. The imaginary circle circumference 25 is smaller than the inner circumference of the inner tool storage 5. In this embodiment, the transfer device 9 has a distance 27 (offset) from the center point or the rotation axis 18. The distance 27 corresponds essentially to the radius of the (imaginary) circle with the circle circumference 25. This variant of the bending tool storage device 1 has an asymmetrical design, whereby the load, in particular on the front side of the bending press 20, is reduced can.
    Of course, all embodiments of a bending tool memory shown in FIGS. 1-7 can also be realized with guide rails, the course directions of which - as exemplified in FIG. 8 - have a tangential component.
