Definitions
- 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 in a tool storage and / or for removing at least one bending tool from a tool storage.
- CH668035A5 discloses a bending press and mechanism for changing
- Bending tools are suspended in a SpeI cher 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 a lot of space must be made available for the movement of the support arm.
- the approach and pivoting of the arm in the direction of the tool holder of the bending press requires a complex sequence of movements.
- a great deal of time in changing is also the result of the fact that the bending tools only individually, i. can be transferred one after the other.
- EP2143506B 1 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 feed and spills them into the bending press.
- the transfer device is vertically and horizontally movable for this purpose; the hook can be rotated additionally.
- the object of the invention is to eliminate these deficiencies and to provide a bending tool memory which can be dimensioned to save space 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 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.
- the first section more guide rails per angle unit are arranged (as in the second section) and therefore more bending tools can be accommodated.
- the solution according to the invention the fact be taken into account that bending tools have different size and shape.
- the first section can be used specifically to accommodate shorter and / or narrower bending tools.
- longer and / or wider bending tools can be accommodated in the second section become.
- 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 to 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 by angular distances from each other; the guide rails each extend in a direction from inside to outside.
- the guide rails extend from the inner circumference in the direction of the outer circumference of the tool storage.
- the guide rails 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.
- 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 has no tangential component here) or in a direction with a radial component.
- the guide rails each extend in directions with tangential component.
- the guide rails extend in this embodiment from the inside out, but inclined to the (pure) radial direction.
- the length of the individual guide rails can be increased by this measure.
- 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, partial ring or disc shape (or the center point) of the respective tool store.
- the radial direction or the radial direction component of the guide rails in each case refers to a center, which may be defined by a ring shape, partial ring shape or disc shape (or circular shape) of the bending tool memory. Due to the course the individual guide rails in each case in the radial direction or in a direction with a radial component increases the distance between adjacent guide rails of a tool storage in the radial direction (ie from the inner periphery in the direction of the outer periphery of the bending tool storage). This means that adjacent guide rails have an angular spacing from one another (or are not parallel to one another).
- 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 store thus has along its circumference the first portion in which the angular distance between adjacent guide rails is smaller than in the second portion along its circumference.
- 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 in this case be spaced apart from one another such that in the area of the outer circumference (short) bending tools can be placed next to one another (i.e., in adjacent guide rails) without touching each other.
- the lateral spacing between adjacent guide rails could already be so small that touching occurs 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.
- a preferred embodiment is characterized in that the second angle is at least 1.3 times, preferably at least 1.5 times, particularly preferably at least 2 times, as large as the first angle.
- the packing density in the first section ie the number of softening bending tools per room unit, can thus be increased by the corresponding factor.
- a preferred embodiment is characterized in that the Biegewerkmaschineschwi- is rather rotatable, in particular about a defined by the radially extending guide rails center axis of rotation. Thereby, each guide rail can be moved into a working area, e.g. a transfer device to be moved.
- a preferred embodiment is characterized in that the Biegewerkmaschinemaschinei- is more 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.
- 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, the bending tools being closer to the outer ends of the guide rails than the inner ends, preferably in the region the outer ends of the guide rails are arranged.
- 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 - on The radial direction - inner ends at most as large, preferably smaller, than the dimension of a held in a guide rail of the first section bending tool is 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 do without first and second sections, is based on the idea that the guide rails are so close to each other, i. have such a small angular distance from each other that it could also lead to collisions between see bending tools. But this is prevented by (a) the short bending tools - radially seen - are positioned outside, where the distance between the guide rails is greater than inside, and (b) the long bending tools occupy at most only every second guide rail so that it does not Collision can come.
- the storage specifications (a) and (b) can also be combined, so that in each case a short bending tool is accommodated 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 inner - related to the radial direction - ends at most as large, preferably smaller than the dimension of a in a guide rail held bending tool perpendicular to the direction of the guide rail.
- the common idea of increasing the storage capacity also lies here.
- a bending tool storage device for storing bending tools, comprising at least one storage unit comprising an outer tool storage which is annular or semi-annular and a plurality of (eg in the radial direction or in a tangential component direction ) Has guide rails for holding and guiding bending tools, wherein the storage unit comprises at least one inner tool storage, which is arranged within the outer tool storage and a plurality of extending in the radial direction
- 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. Turning the tool train storages against one another enables complex maneuvering operations in which the bending tools are moved along the guide rails.
- the outer tool storage and the at least one inner horri-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.
- the storage or charging device With the storage or charging device according to the invention, it is also possible to accommodate a plurality of bending tools in a guide rail in a row one behind the other, whereby the storage density of the tool storage is further increased.
- bending tools can be temporarily moved into the respective other tool store and stored there (in between).
- the two mutually rotatable tool stores allow bending tools to be moved from one (or a first) guide rail of the tool store into another (or second) guide rail of the same tool store.
- Such shunting operations are carried out 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 continuously inserted in guide rails during the maneuvering maneuver (ie, 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) takes place in that the two guide rails in zuei- nander aligned orientation (whereby a continuous guide portion is formed), and by moving the bending tool from the one guide rail in the other guide rail.
- Intermediate steps, which involve the removal of a bending tool from a guide rail and the replacement, are not required due to the principle according to the invention.
- the outer tool storage and / or the inner tool storage 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 centers which are defined by the ring shape, partial ring shape or disc shape of the tool storage together. 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 most, there is a small gap between the tool feed so that the bending tools can be moved directly from one tool store to the other.

- 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 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 guide rails is arranged 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 or the other (s) inner tool storage facilities have from the inside outwardly extending guide rails, which by relative rotation with guide rails of the adjacent tool storage in cursory - lo tende alignment can get.
- a storage unit may also have 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 storage unit 3 comprises at least two inner tool stores 5, 6, which are rotatable relative to one another.
- FIG. 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 bending tools arranged one behind the other (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-hand 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 more bending tools 2 used in a bending press 20.
- the 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 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 guide rail 14 of the tool storage.
- 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, in which at least one bending tool 2 by a guide rail 14, 15 of a tool storage 4, 5 in a guide rail 15, 14 of the other tool storage 5, 4 is moved (Fig. 2) and in which the a tool storage 4, 5 and the other tool storage 5, 4 are rotated relative to each other.
- shorter bending tools 2 are deposited in the guide rails 14 of the outer tool storage 4 than in the guide rails 15 of the inner tool storage 5.
- shorter bending tools 2 are deposited in the guide rails of the first section 11 than in the guide rails of the second section 12.
- 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 extend in this embodiment from the inside to the outside and from the inner periphery to the outer periphery of the tool storage.
- the transfer device 9 has a distance 27 (offset) from the center or the axis of rotation 18. The distance 27 corresponds essentially to the radius of the (imaginary) circle with the circumference 25.
- This variant of the bending tool storage device 1 has an asymmetric design, whereby the load, in particular on the front side of the bending press 20 can be reduced.
