Definitions
- the invention relates to a device for separating a number of workpieces from a strip of material having a separation unit which can be fed to the strip of material and in which by loading the material strip the workpiece is detachable from the strip of material, and wherein the device comprises a transport device, by which a workpiece strip containing the workpieces separated from the material strip and at least one residual strip containing the remaining region of the material strip can be moved further in a transport direction.
- the invention further relates to a method for separating a number of workpieces from the strip of material, wherein the strip of material from a Transport device of a device is fed to a separation station, wherein in this separation station from the strip of material a number of workpieces are removed, wherein a workpiece strip containing these workpieces and at least one of the remaining area of the material strip processed in the separation station containing residual strip are moved out of the separation station.
- the separation unit of the device in the transport direction of the Materiaist presents a separating station, by means of which the workpiece strip containing the workpieces can be separated in a first plane and the residual strip or strips can be separated into at least one second plane spaced from the first plane.
- the method according to the invention provides for the workpiece strip and the residual strip or strips to be spatially separated from one another in a separating station arranged downstream in the direction of transport of the strip of material of the separating station, such that the workpiece strip is in a first plane and the residual strip or strips of the material strip in one are transported to the aforementioned first level spaced further level.
- the measures according to the invention is achieved in an advantageous manner that with the inventive device and the inventive method an efficient production of dimensionally stable workpieces, even of filigrane workpieces, is made possible, as by the measures according to the invention the men during the separation process Deformation forces acting on the workpiece are eliminated or at least substantially reduced.
- the spatial separation of the residual strip containing the remainders of the strip of material allows a simple removal thereof from the device according to the invention. Another advantage here is that the remainders of the material strip arising during the separation process are coherent, whereby the removal of the residual material is simplified, which likewise contributes to a higher cycle rate.
- the separating station contains a separating element, which is preferably wedge-shaped. By this separating at least one residual strip is at least laterally wegbewegbar from the transport direction of the strip of material.
- the separating element of the separating station of the device according to the invention thus facilitates the spatial separation of one or both remaining strips from the workpiece strip containing the workpieces.
- a further advantageous development of the invention provides that the separating station has at least two channels, wherein at least one residual strip can be guided in the first channel of the workpiece strip and at least one second channel, the invention being provided according to a further advantageous development in that at least one lower guide surface of the at least one second channel is arranged slightly inclined with respect to a working plane of the device.
- the at least one channel receiving a residual strip extends inclined to the transport direction of the workpiece strip.
- FIG. 1 shows a schematic representation of an exemplary embodiment of a device for fl exing a workpiece from a strip-shaped base material
- FIG. 2 shows a plan view from the direction II of FIG. 1,
- FIG. 4 shows a detail A of FIG. 3
- 5 shows a further section along the line AA of FIG. 2
- FIG. 6 shows a detail A of FIG. 5
- FIG. 7 shows a section along the line B-B of FIG. 2,
- FIG. 8 shows a detail B of FIG. 7,
- FIG. 9 shows a section along the line C-C of FIG. 2,
- FIG. 10 shows a detail C of FIG. 9,
- Figure 11 shows a first embodiment of a strip
- Figure 12 shows a second embodiment of a strip.
- FIGS. 1 and 2 a device, generally designated 1, for separating out workpieces W from a strip of material S is shown schematically.
- This is essentially composed of a known and therefore no longer described separation station 10, which in a known manner for separating out a workpiece W from the material strip S is used, and a separating station 20, in which -. as also described below - the workpieces W are spatially separated from the remainder of the material strip S and the remainder of the material strip S is removed.
- FIG. 2 shows a plan view of the working plane of the device 1, the upper part of the separating station 10 shown in FIG. 1 has been omitted here for reasons of clarity.
- the material strip S is - in the illustration of Figure 2 - from the right of the device 1 in a per se known ter and therefore not described manner of a transport device (not shown) supplied. It then passes to the separating station 10 and to the separating station 20. A workpiece strip WS containing the workpieces W is led out of the device 1 for further processing of these workpieces W.
- the remainder of the material strip S here two residual strips S ', S "(see Also FIG. 11) are removed from the device 1 through discharge openings 20a, 20b.
- the workpiece strip WS and the two remaining strips S 'and S "of the originally planar material strip S lie in different planes. It can be seen from the aforementioned figure that the workpiece strip WS lies below the residual strips S and S ".
- Such an approach has the advantage that in a simple manner, a precise and dimensionally stable Fler ein of such workpieces W, especially filigree workpieces W, is possible because of the reasons explained below deformation of the workpieces W in the separation process, as in the known devices can occur, eliminated or at least substantially reduced. This is because any deformation forces arising during the separation process are dissipated by the measures described into the two residual strips S ', S "and thus do not lead to a deformation of the workpieces W to be produced.
- Another advantage of the procedure described is that it is now possible to dissolve even filigree workpieces W in a single separation process from the strip of material S. It is therefore no longer necessary in the case of the described device 1 that the production of such workpieces W takes place in two or more successive partial separation processes. This leads advantageously to an increased production rate.
- the separation operation performed by the separation station 10 is a shearing operation.
- the measures described are not limited to such a shearing process. It can also be a punching or a cutting process for Fleraustrennung the workpieces W from a strip of material S are used or another material-separating method, which is based on the action of forces on the material strip S.
- the changes to be made by the person skilled in the art are obvious to him and therefore need not be described any further.
- FIG. 4 which shows detail A of FIG. 3 on an enlarged scale, the area of material forming the workpiece W has been separated therefrom by a corresponding loading of the material strip S by the punch of the separating station 10. This material region thus lies in the cutting insert 25 of the separating station 10 on an ejector 26.
- the workpiece piece W, and thus a workpiece strip WS containing the workpieces W, are thus located below the edge region of the material strip S forming the remaining strips S ', S ".
- FIGS 5 and 6 now show the separation station 10 in its top dead center.
- FIG. 6 showing a detail A of FIG. 5 that the ejector 26 of the separating station 10 has been moved upwards, so that the workpiece W has been moved out of the cutting insert 25.
- the workpiece strip WS containing the workpieces W lies in a first plane and the two residual strips S ', S "lie in a second plane above the abovementioned first plane.
- Such a separation process is known and therefore need not be further described.
- the material strip S is advanced further.
- the workpiece strip WS is guided in a first channel 22a extending in the main body 20 of the separating station 20.
- the first residual strip S is guided in a channel 22b and the second residual strip S "in a channel 22c of the separating station 20.
- the channel 22a runs in a substantially straight line in the transport direction, while the channels 22b and 22c extend at an angle to the transport direction and thus to the channel 22a.
- FIGS. 7 and 8 now show a section along the line BB of FIG. 2.
- the workpiece W which has been separated out of the strip of material S as described above is thus already in the separating station 20 following the separating station 10.
- This has - as is apparent in particular from FIG It can be seen - a separating element 21, which is designed wedge-shaped in the embodiment shown here, wherein the narrow end of this wedge-shaped Separierele- element 21 of the separation station 10 faces.
- the separating element 21 has the task of deflecting the remaining strips S ', S ", which run parallel to one another, to the outside, so that the residual strips S' and S" -as best seen in FIG. 1 -by corresponding discharge openings 20a, 20 b can be removed from the device 1.
- the separating station 20 has channels 22a, 22b and 22c for the different partial strips WS, S 'and S "of the material strip S led out of the separating station 10, which - in a drawing plane of FIG 2 and thus the working plane 2 of the device 1 orthogonal Z-direction seen - run in different fleas.
- a central channel 22a which runs in a lower first plane, serves to guide the work piece W containing workpiece strip WS.
- channels 22b, 22c are arranged, which serve to guide the first residual strip S 'and the second residual strip S ".
- These two channels 22b, 22c are arranged in a second plane lying above the first plane.
- the lower guide surface 23b of the channel 22b is not parallel to the lower guide surface 23a of the channel 22a receiving the workpiece strip WS, but slopes slightly outwardly sloping with respect to the working plane 2.
- the lower guide surface 23c of the channel 22c is also arranged sloping downwards.
- the channels 22b and 22c receiving the residual strips S 'and S do not run parallel to the channel 22a receiving the workpiece strip WS, but are arranged to extend obliquely outward to this channel 22a.
- Flier notebook is in an advantageous manner the spatial separation of the workpiece strip WS of the remaining strips S 'and S "allows in a direction inclined to the transport direction.
- both channels 22b and 22c it is not necessary for both channels 22b and 22c to be inclined at the same time, for certain purposes it may well be sufficient if only one of these two channels 22b, 22c moves away from the channel 22a.
- FIGS. 9 and 10 now show a section along the line C-C of FIG. 2. It can be seen that the lower guide surface 23c of the channel 22c now again runs approximately parallel to the lower guide surface 23a of the channel 22a. As described above, the two remaining strips S ', S "have already been sufficiently separated by the separating element 21 of the device 1, and above all the residual strip S" guided in the channel 22c is already sufficiently far away from the workpiece strip WS is, further tilting of the remaining strip S "is no longer necessary. As can also be seen from the figure, the wider residual strip S ', which is guided in the channel 22b, partly still above the workpiece strip WS, so that a further lifting of this residual strip S is expedient.
- channels 22a-22c described herein is exemplary only. It can, depending on the particular application of the device 1, be changed within wide limits.
- the configuration of the channels 22a-22c depends in particular on the width of the respective strips WS, S 'and S ". It should be chosen such that, on the one hand, the workpiece strip WS can be transported away from the device 1 by the remaining strips S, S "unhindered, and, on the other hand, the residual strips S ', S" can be easily removed from the device 1.
- the channels 22a-22c are formed as recesses in the main body 20 'of the separating station 20.
- any configuration is possible in which it is achieved that the strip running in the corresponding channel 22a-22c is channeled in a specific direction, that is, guided in this direction.
- the term "channel” is thus understood in its broadest meaning and functionally oriented and therefore not limited in geometric-constructive respect to the "trench-like" design shown in the described embodiment.
- the device 1 preferably has a processing station 30 arranged in front of the separating station 10, in particular a punching or cutting station, which serves to bring the aforementioned openings D into one or preferably both edge regions of the material strip S, by the corresponding material regions be separated out of the strip of material S.
- a processing station 30 arranged in front of the separating station 10, in particular a punching or cutting station, which serves to bring the aforementioned openings D into one or preferably both edge regions of the material strip S, by the corresponding material regions be separated out of the strip of material S.
- FIG. 12 now shows a further embodiment of such a material strip.
- the difference between the material strips S of Figures 11 and 12 is that the material strip S of Figure 11 is now formed in two parts, d. H. he only has the workpiece strip WS and only a residual strip S 'on.
- the person skilled in the art can see from the above description how he has to modify the device 1 described above.
- only two guides 22a, 22b are then required and the separating element 21 may preferably also be dispensed with.
- the described measures advantageously produce a more efficient production of workpieces from a strip-shaped, strip-shaped or plate-shaped basic body such as the material strip S, by way of which the mode of operation of the described device 1 has been explained by way of example. is possible.
- a further advantage of the measures described is that the workpieces W can now be separated out of the material strip S in a single separation process, whereby the production speed of such a device 1 is markedly increased.
