    The invention relates to a press brake for bending metal sheets.
    From EP 2 364 789 B1 a press brake is known, which has a tool manipulation device for taking out individual beer tools from a tool holder of the press brake. The tool manipulation device has a carriage, which is displaceably mounted on the press brake in a direction parallel to the bending edge. On the carriage three manipulation arms are arranged, which are designed to accommodate bending tools. By means of the manipulation arms, individual bending tools can be taken out of the tool holder of the upper press bar, thereby enabling a displacement of the individual bending tools in the tool holder of the upper press bar.
    The press brake described in EP 2 364 789 B1 has the tail, that the tool manipulation device is designed only for receiving three bending tools and thus the flexibility of the tool manipulating device is limited.
    The object of the present invention was to overcome the disadvantages of the prior art and to provide an apparatus and a method by means of which the tool changing operation can be carried out as quickly as possible.
    This object is achieved by a device and a method according to claims 1 and 10.
    According to the invention, a press brake is designed for bending metal sheets. The press brake comprises a first fixed pressing beam, as well as a second pressing beam displaceable relative thereto; arranged on the press beam or trained tool holders for receiving bending tools; a tool storage for storing unused bending tools; a tool changing device, which is designed to move the bending tools between the tool holder and the tool storage. The tool storage has a Vorrüstspeicher and a main memory, wherein the Vorrüstspeicher end is arranged directly adjacent to the pressing bars and the main memory is arranged on the Vorrüstspeicher, and wherein the Vorrüstspeicher and the main memory are each designed to accommodate bending tools.
    The inventive construction of the press brake has the advantage that in the Vorrüstspeicher the bending tools needed for the next bending process can be prepared and already arranged sorted one another. This preparation of the bending tools can be carried out during the operation of the press brake, whereby the operation of the press brake is not restricted or hindered. The actual changing process of the bending tools can then be carried out as quickly and efficiently as possible, since the bending tools are already sorted sorted in Vorrüstspeicher and only need to be moved into the tool holder of the press brake into it. The main memory is used to store a larger number of bending tools in the tool storage, or to sort the bending tools in the Vorrüstspeicher so that they can be sorted arranged in Vorrüstspeicher.
    Furthermore, it may be expedient if the Vorrüstspeicher has at least two first storage rails for receiving a bending tool, which first storage rails are positioned in extension to the tool holder of the first press beam and at least two second memory rails for receiving a bending tool, which second memory rails in extension to the Wherein the main memory has at least two first memory rails for receiving a bending tool, which first memory rails of the main memory in extension to the first memory rails of Vorrüstspeichers can be brought and wherein the main memory has at least two second memory rails for receiving a bending tool, which second memory rails of the main memory can be brought in extension to the second memory rails of the Vorrüstspeichers. The advantage here is that in each case two memory rails are formed in the Vorrüstspeicher and in the main memory, so that the bending tools can be moved from the tool holder in the Vorrüstspeicher or from this into the main memory, the presence of can be achieved by at least two memory rails, that a storage rail can receive the removed from the tool holder bending tools and the second storage rail can accommodate the prepared for mounting the tool holder bending tools.
    Furthermore, it can be provided that the first memory rails of the Vorrüstspeichers are arranged on a first Vorrüstspeicherschienenmanipulationsvorrichtung and that the second memory rails of Vorrüstspeichers are arranged on a second Vorrüstspeicherschienenmanipulationsvorrichtung and that the first memory rails of the main memory on a first main memory rail manipulation device are arranged and that the second memory rails of the main memory are arranged on a second main memory bar manipulating device. The advantage here is that the storage rails can be moved by means of rail manipulation devices and thus a variety of storage rails of the Vorrüstspeichers can be aligned with the tool holder. In addition, a variety of memory rails of the Vorrüstspeichers can be aligned with a variety of memory rails of the main memory to each other by this measure. In particular, it can be achieved that the individual storage rails or the tool storage can be aligned with each other so that a smooth movement of the bending tools between them is made possible.
    In addition, it can be provided that the individual rail manipulation devices are designed as paternoster, wherein two mutually spaced-apart circumferential traction means are formed and the individual storage rails are each coupled at their longitudinal ends with the traction means. The advantage here is that the memory rails can be moved as easily and inexpensively by a rotating paternoster assembly, and beyond the space required for this arrangement, the memory rails can be kept as low as possible.
    Also advantageous is an expression, according to which it can be provided that the individual storage rails are coupled by means of a hinge connection with the traction means, and the storage rails are coupled to the traction means such that the storage rails always remain aligned with respect to their top and bottom due to gravity , The advantage here is that the memory rails remain the same orientation at all positions in circulation. This avoids that the bending tools received in the storage rail can fall out of the storage rail during the rotation of the storage rail in the paternoster system.
    According to a development, it is possible that the tool changing device comprises a manipulation head, which is designed for selective coupling with one of the bending tools in order to be able to displace it in the horizontal displacement direction along the tool holder. The advantage here is that the bending tool can be coupled to the manipulation head such that a displacement of the bending tool by means of the manipulation head is possible.
    Furthermore, it may be expedient if the manipulation head has a driving mandrel, which is designed for engagement in a bending tool, wherein the bending tool has a recess into which the driving mandrel can be inserted, and that the driving mandrel is coupled to an actuator, by means of which actuator of Mitnehmerdorn is inserted into the recess of the bending tool. The advantage here is that by means of the driving mandrel the best possible connection between the manipulation head and the bending tool can be made, so that the bending tool can be moved from the manipulation head.
    In addition, it can be provided that the manipulation head is arranged laterally of the tool holders and is displaceably mounted by a guide rail in the horizontal displacement direction along the tool holder, wherein the guide rail extends from the tool holder to at least in the Vorrüstspeicher the tool memory. The advantage here is that by this measure the manipulation head or the complete tool changing device is not the operation of the press brake in the way.
    Furthermore, it can be provided that the guide rail extends over the entire length of the tool holders and both via the Vorrüstspeicher and the main memory of the tool storage. The advantage here is that the bending tools can be moved with only one manipulation head on the entire length of the tool holder and the tool storage.
    Furthermore, in a method for changing bending tools on a press brake it can be provided that the method comprises the following method steps: preparing a change of the bending tools, wherein the bending tools required for the next bending operation in the required order by means of a tool changing device from a storage rail of a main memory a tool memory are moved into a storage rail of a Vorrüstspeichers the tool memory; - Performing the tool change, wherein bending tools, which are accommodated in a press beam arranged tool holder, are moved by means of the tool changing device from the tool holder in one of the free memory rails of the Vorrüstspeichers and wherein the prepared in the storage rail of Vorrüstspeichers bending tools by means of the tool changing device from the storage rail of Vorrüstspeichers be moved into the tool holder; - Post-processing of the tool change, the shifted from the tool holder into the storage rail of Vorrüstspeichers bending tools optio nal be moved from the storage rail of the Vorrüstspeichers in the memory rail of the main memory.
    An advantage of the inventive method for changing bending tools on a press brake is that the change process for changing the bending tools is still prepared during operation of the bending machine. During the actual change process of the bending tools, these are already sorted in the correct order and can thus be exchanged as easily and quickly as possible between the tool storage and the storage rail.
