    The invention relates to a method for simultaneously displacing at least two bending tools held in a rail of a tool holder, which form a row along the rail, by means of a transporting device, in particular a method for feeding a bending press with bending tools and / or for removing bending tools from a bending press , The invention also relates to a bending press and / or feeding device for feeding a bending press with bending tools and / or for exchanging bending tools and / or for storing bending tools. During simultaneous feeding of multiple bending tools along an elongate tool holder by means of a transport device, during (for example during the loading process), the bending tools must be removed from the bending press individually, since the hitherto known transport devices can only be coupled to a bending tool. The coupled bending tool is then pulled out of the bending press. The steps, approaching the transport device, coupling to the bending tool and pulling out of the bending tool, must be carried out separately for each bending tool. This is a complicated and time-consuming procedure. Another disadvantage is that in a (connected to the bending press) feeding device complex maneuvering maneuvers are required to store the individually transported bending tools. It should be noted that the transport device often uses the same rail as a guide and therefore this is to be kept free from any loading or unloading process.
    The invention has the aim of eliminating these disadvantages and to provide a method which allows simultaneous displacement of at least two bending tools by pulling by means of the transport device. The effort in loading or removal of bending tools should be significantly reduced. The (pulling out) the bending tools should be designed to save time compared to known solutions.
    This object is achieved by a method mentioned above in that the transport device is moved in a first direction along the rail to the first bending tool of the series and a first section of the transport device extending to the last bending tool of the series and arranged on the last bending tool of the Row is coupled and that the transport device is moved with the series of bending tools in the direction opposite to the first direction.
    The method of the transport device in the opposite direction to the first direction means that the bending tools are pulled by the transport device. In this case, the last bending tool is coupled to the first section of the transport device, whereby the other bending tools of the series are forcibly pulled along. The inventive measure several bending tools can be pulled simultaneously, with only a coupling to the last bending tool is required. The invention goes hand in hand with a reduction of the (shifting) effort and with a significant saving of time.
    The first direction corresponds to the direction that points (along the rail) from the first bending tool of the series to the last bending tool of the series. The direction opposite to the first direction corresponds to the direction that points (along the rail) from the last bending tool of the series to the first bending tool of the series.
    A preferred embodiment is characterized in that the bending tools of the row held in the rail each have at least one passage extending in the longitudinal direction of the rail, in particular a bore, the first section of the transport device passing through the passages of the bending tools of the row at least up to the first last bending unit of the series is laid. The passages of the individual bending tools are aligned (at least partially) with one another and form a continuous passage through which the first section is laid or threaded. The passages therefore serve as a guide for the first section. The first section can thereby be laid in an elegant manner along the bending tool row, wherein the passages or the continuous passage represent a guide for the first section. At the same time, the first section is protected from external influences during the transport of the bending tools.
    The passages, in particular holes, serve to reduce the weight of the bending tools and can therefore already be introduced. With the above embodiment, in addition to a weight reduction, the passages additionally fulfill the function of guiding the first section of the transport device.
    In an alternative embodiment, the first section of the conveyor could also be located adjacent to the bending tools, i. outside of the bending tools, the series are routed and then joined with the last bending tool of the series.
    A preferred embodiment is characterized in that the first section of the transport device comprises an elongated, preferably flexible tensile transfer means. An elongated transmission means is not only particularly space-saving, but can also be easily inserted into the passages of the bending tools.
    A preferred embodiment is characterized in that the first section of the transport device comprises a preferably operable by a drive coupling device with which the last bending tool of the series is coupled to the transport device, wherein the coupling device preferably a spreader and / or a clamping device and / or a driver device comprises. The drive of the coupling device can e.g. be accommodated in a trained as a shuttle second section of the transport device.
    A preferred embodiment is characterized in that the first portion of the transport device comprises two, along its longitudinal extent mutually displaceable tension and / or pressure transmission elements, wherein the coupling means is actuated by a mutual displacement of the tensile and / or pressure transmission elements. The actuation of the coupling device can take place from elsewhere, e.g. from the second section (e.g., shuttle) of the transport means described hereinafter.
    A preferred embodiment is characterized in that the transport device is guided in the same rail in which the bending tools are held.
    A preferred embodiment is characterized in that the transport device has a second section movable along the rail, in particular a shuttle, and that the first section is movable relative to the second section, preferably extendable from the second section, in particular rollable. The second section is moved up to the maximum of the first bending tool (i.e., the second section remains outside the bending tools). Subsequently, the first section is extended and thus positioned along the bending tools.
    A preferred embodiment is characterized in that the second section of the transport device comprises a housing in which the first section can be accommodated, in particular during the approach of the transport device to the first bending tool of the series. This protects the possibly filigree first section. In addition, the first section can be selectively extended by appropriate guides in the area of the passages, so that a reliable 'threading' takes place.
    The object is also achieved with a bending press and / or feeding device for feeding a bending press with bending tools and / or for exchanging bending tools and / or for storing bending tools, with a tool holder designed as a rail and a transport device movable along the rail. In this case, the transport device has a first section, which can be arranged along a series of bending tools held in the same rail. The term "along a series of bending tools" is to be understood to include both placement of the first portion within the bending tools (in passages) and placement of the first portion externally adjacent to the bending tools.
    A preferred embodiment is characterized in that the bending press and / or charging device is designed for carrying out a method according to the invention.
    A preferred embodiment is characterized in that the bending press and / or charging device comprises at least two, held in the rail bending tools, which form a row along the rail and each have at least one extending in the longitudinal direction of the rail passage, in particular a bore, wherein the passages of the bending tools are aligned with each other, and that the first section of the transport device can be laid through the passages of the bending tools in the row.
    A preferred embodiment is characterized in that the first section of the transport device comprises an elongated, preferably flexible tensile transfer means.

    Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions.
    The task underlying the independent inventive solutions can be taken from the description.
    Above all, the individual figures shown embodiments may form the subject of independent solutions according to the invention. The relevant objects and solutions according to the invention can be found in the detailed descriptions of these figures.
    For the sake of order, it should finally be pointed out that, for a better understanding of the structure of the bending press, feeding device and transport device, these or their components have been shown partially unevenly and / or enlarged and / or reduced in size.
    Based on the sections of a bending press 1 and a charging device 2 shown in Fig. 1, the inventive method is explained in detail. This is a method for the simultaneous displacement of at least two bending tools 4, 5, 6 held in a rail 3 of a tool holder.
    In the illustrated embodiment, three bending tools 4, 5, 6, which form a row along the rail 3, are displaced by means of a transport device 7. The method may be e.g. to a feed of the bending press 1 with bending tools 4, 5, 6 and / or to the removal of bending tools 4, 5, 6 from the bending press 1 act.
    In a first step, the transport device 7 is moved in a first direction 11 along the rail 3 to the first bending tool 4 of the series. Subsequently, a first section 8 of the transport device 7 is arranged such that it extends to the last bending tool 6 of the series. In other words, the first section 8 is arranged along a series of bending tools 4, 5, 6 held in the same rail 3.
    Then, the first section 8 is coupled to the last bending tool 6 of the series. Now the transport device 7 can be moved with the row of bending tools 4, 5, 6 in the opposite direction to the first direction 11 12th In the illustrated embodiment, the bending tools are thus pulled out of the bending press 1 in the direction of the charging device 2.
    In the illustrated embodiment, the bending tools 4, 5, 6 of the row held in the rail 3 each have at least one passage 14, 15, 16 extending in the longitudinal direction of the rail 3, in particular a bore. The passages 14, 15, 16 are aligned with each other and form a passageway continuous along the row of bending tools 4, 5, 6. The first section 8 of the transport device 7 is laid through the passages 14, 15, 16 of the bending tools 4, 5, 6 of the row at least until the last bending tool 6 of the row (here: into the region of the end of the last bending tool 6). Fig. 4 shows a bending tool 4 with a passage 14 in section.
    The first section 8 of the transport device 7 comprises an elongate, preferably flexible, tensile transfer means that is 'threaded' through the passages 14, 15, 16.
    The first section 8 of the transport device 7 comprises in its end region a (preferably by a drive) operable coupling device 10, with which the last bending tool 6 of the series is coupled to the transport device 7. The drive (not shown) of the coupling device 10 may e.g. be housed in the form of a shuttle second section 8 of the transport device 7. The coupling device 10 of FIGS. 1 and 2 is designed in the manner of a driving device. Alternatively, the coupling device may also comprise a spreading device (FIG. 3) and / or a clamping device.
    As shown in more detail in the embodiment of FIG. 2, the first section 8 of the transport device 7 may have two tension and / or pressure transmission elements 17, 18 which can be displaced relative to one another along their longitudinal extent. In this case, a transmission element 17 as (tubular or tubular) envelope may be formed, while the other (rope or chain-shaped) transmission element 18 extends within the enclosure. The coupling device 10, which comprises here pivotable driver can be actuated by a mutual displacement of the tension and / or pressure transmission elements 17, 18. In this case, e.g. that transmission element 18 are moved relative to the transmission element 17 along the arrow shown in FIG. 2, whereby the drivers of the coupling device 10 are swung out.
    3 shows a further variant of a coupling device 10. By inflating a balloon within the passage 16 of the last bending tool 6, a frictional connection is made. The balloon is formed in the end portion of the first portion 8 and presses against the inner walls of the passage 16. Instead of an inflatable balloon and other spreading or clamping devices can be used as coupling devices.
    From Fig. 1 it can be seen that the transport device 7 is guided in the same rail 3, in which the bending tools 4, 5, 6 are held. The transport device 7 has a movable along the rail 3 second section 9, in particular in the form of a shuttle. The first section 8 is movable relative to the second section 9 or extendable from the second section 9 (here: roll-bar). As a result, the first section 8 enters the passages 14, 15, 16 and passes through them.
    The trained in the form of a shuttle second section 9 of the transport device 7 is moved by means of an elongated train / pressure transmission means 20, in particular a transport chain along the rail 3. The tension / pressure transmission means 20 may be formed as a chain, rope, or the like, and is moved by a drive (indicated in FIG. 5 as rollers). The train / pressure transmission means 20 may itself be guided in the rail 3.
    The second section 9 of the transport device 7 may comprise a housing 19, in which the first section 8 is housed - in the retracted position. This is the case in particular during the approach of the transport device 7 to the first bending tool 4 of the series.
    5 finally shows a bending press 1 and a feeding device 2 coupled to the bending press 1 for feeding the bending press 1 with bending tools 4, 5, 6 and / or for exchanging bending tools 4, 5, 6 and / or for storing bending tools 4, 5, 6. These are each designed to carry out a method according to the invention.
    As can be seen from FIG. 5, the principle according to the invention can be used both for lower tools and for upper tools.
