Description

TECHNICAL AREA

The present invention relates to a processing machine for flat material parts, comprising a machine frame, a lower beam, an upper beam, at least one processing tool assigned to the lower beam or upper beam and held on the machine frame, a control unit for controlling a processing sequence with the processing tools, an infeed table on which the Flat material part can be placed for positioning in the processing machine, and a placement unit for predetermined positioning of the flat material part on the feed table, wherein the feed table can be moved back and forth from a parking position in an extension direction into a loading and unloading position and wherein the placement unit has a plurality of Has suction cup units with which the flat material part can be picked up and positioned by the feed table, and it relates to a method for this.

STATE OF THE ART

A processing machine for flat material parts with a loading unit is from EP 3 208 008 A1 known to the applicant. This placement unit makes it possible to improve, in particular to speed up, the feeding process of the placed flat material part.

From https://www.youtube.com/watch?v=Eg3Ovmc_wZQ a processing machine for flat material parts from ASCO with a laying unit is known (dated 3.

February 2015) that was shown at a trade fair. The placement unit is a turning unit in which a group of suction cups are each arranged between individual sections of the subdivided feed table and rotate the workpiece about an axis parallel to the bending axis, which bending axis is pivoted out from below the feed table above the feed table, with the suction cups on transverse attached to the bending axis arranged arms. In this case, the arms have a predetermined length in order to be able to grip the flat material part from behind and turn it over. The cheeks of the processing machine must be moved far apart in order to achieve a sufficient height for the open cheeks reach, so that flat material parts of a certain width can be turned over. Turning in the machine also speeds up the infeed or feed process, since the next bending step can be tackled more quickly. https://www.youtube.com/watch?v=VtqX869N3Tk shows a company video of a processing machine for flat material parts with the above function, which forms the basis for the preamble of claim 1. https://www.youtube.com/watch? v=WwuX11ckxmM&ab_channel=jornsswiss shows another example of a similar processing machine.

U.S. 2016/107847 A1 shows a handling device for a folding machine. The part to be bent can be gripped on one of its flat sides by forces acting on one side of the flat side in a pulling manner at several longitudinally consecutive points, after which the holding unit can in turn be pivoted relative to a pivotable carrier unit about a first pivot axis parallel to the longitudinal direction, with the pivotable carrier unit pivotable relative to a pivotable support base about a second pivot axis parallel to the first pivot axis, and wherein the pivotable support base is movable in a direction transverse to the second pivot axis by a support base moving unit.

WO 97/32677 A1 shows a device for bending a metal sheet, comprising a frame, a stationary lower beam with a lower clamp, a movable upper beam with an upper clamp, the clamps each having a clamping surface for clamping a metal sheet in a working position, a lower bending beam and a Upper bending beam for bending a clamped metal sheet upwards or downwards, the bending beams being mounted on both sides in a carrier plate so that they can rotate about a corresponding axis, the carrier plates being movably mounted in the frame in such a way that the lower or upper bending beam is in can be moved to a working position in which its axis lies essentially in the plane of the clamping surface of the lower or upper clamp. Also provided is a device for holding the sheet metal, the holding device being provided with a substantially C-shaped frame with a carriage which is reciprocable on a carriage bed between a front and a rear position, the legs of the C- shaped frame each carry a lower and an upper disc, which are suitable for engagement with a metal sheet in a working position. In the forward position of the carriage, the legs of the C-shaped frame extend between the top and bottom beams such that the bottom and top discs abut the clamps.

To perform the bending movement, the flexures are attached to the jaws by spatial mechanisms, preferably ball joint couplings, and positioned longitudinally by mechanically or hydraulically actuated displacement devices.

PRESENTATION OF THE INVENTION

Proceeding from this prior art, it is an object of the present invention to specify a processing machine in which the feeding process or unloading process can be accelerated, and this can include a machine-internal feeding as a turning process. The functions are advantageously integrated and also allow a directly turned, machined flat material part to be output.

This object is achieved by the features of claim 1 in a processing machine of the type mentioned. The fact that the placement unit is mounted on the axis of movement associated with the machining tool or tools outside of the associated cheek for a similar pivoting movement results in several advantages. On the one hand, an existing movement axis is used for this placement unit, which works as a turning unit, so that no further elements are necessary. The feature "outside" an associated cheek also means that the mechanism, for example a parallelogram mechanism for moving the processing cheek, is arranged on the side of the cheeks opposite the pivot axis of the upper part and lower part, so that this mechanism does not have to open the upper part too much for the turning process requires. In all Figures 2 to 12 the extension direction of the flat material part is denoted by the double arrow with the reference number 17 . The double arrow is evidently in the cross-sectional view "inside" the inner free space of the machine formed by the upper part and lower part, while said turning unit on the axis of movement assigned to said processing tools for a similar pivoting movement, i.e. for a pivoting movement in the same direction, viewed in cross-section "outside " of the upper part and lower part is mounted.

This makes it possible to turn even wide sheet metal, since the width of the flat component or sheet metal may occupy the free space between the level of the infeed table and the frame of the processing machine downwards or the room height from the level of the infeed table upwards. At the same time it accelerates Procedure for manipulating the sheets, since the clamping cheeks only have to be opened a little, namely only to the extent that the folded ends of the sheet rise above the middle level, i.e. no more than to push out such a machined sheet through the feed table itself. is required.

Advantageously, the suction cups of the placement unit are directly connected to the movement control, for example a parallelogram mechanism, of the processing tools, so that only a corresponding drive has to be provided via the sections of the processing machine. The suction cups can be mounted in a row on a frame. It is also possible to provide two rows of suction cups.

In the parking position of the suction cups, the plane of the suction cups forms an acute angle with the horizontal plane of the feed table, in particular an angle between 70 and 85 degrees. In addition, the infeed table between the lower beam and the upper beam can advantageously be moved out in order to pick up a turned flat component after the suction cups have been released.

This makes it possible, for a placement unit belonging to the upper beam, to let the flat component, which has been turned through 95 to 110 degrees, slide down either onto the feed table or onto a shelf provided underneath by releasing the suction cups.

For a placement unit associated with the lower beam, the flat component turned over 95 to 110 degrees can also slide down onto a shelf provided below by releasing the suction cups.

A further feed can be realized by the placement unit on the upper or lower processing tool if the flat component is placed in the parking position of the upper beam or the lower beam on the then activated suction cups and by pivoting downwards or upwards the flat component placed in this way on the moving infeed table is deposited, so that then, in particular after the retraction table has returned and the flat component has been aligned, processing by the bending tools begins.

If, in addition, the placement unit is positioned transversely to the processing tool or tools laterally within the associated cheek for a feed movement of the flat component in In the direction of the processing edge of the flat component, a loading movement can be accomplished via a rail that is pivotably connected to the upper part, thereby enabling the flat component to be lifted off a loading table. The purpose of the placement unit here is to ensure a feed movement of the flat component in the direction of the processing edge of the flat component. For this purpose, the placement unit can be moved transversely to the processing tool or tools, that is to say parallel to the processing edges of the processing tool or tools, and is connected to this cheek within the associated cheek. This enables the feed movement of a flat component in the direction of the processing edge of the flat component, which enables the device to be loaded forwards in front of the machine directly after a processed flat component has been ejected.

Advantageously, the loading or transfer table is arranged in a parallel plane and higher than the plane defined by the feed table, so that the transfer of the flat component is possible without an additional pivoting movement of the placement unit.

Advantageously, a free space is provided between the transfer table and the feed table as a parking space for the placement unit, so that the processing machine can carry out the clamping movement of the cheeks required for the folding movement of a flat component without this placement unit spatially impeding such a movement.

If, in addition, the placement unit is connected transversely to the processing tool or tools on the side within the associated cheek for a feed movement of the flat component in the direction of the processing edge of the flat component, both placement units are used in combination, so that one person feeds flat components to the machine and these alone after the processing is complete turned over or cannot be removed from the machine.

Technically, the two placement units have in common that they feed the flat component from the outside into the interior without having to open the clamping jaws very far, which takes a certain amount of time with the processing machines. In addition, the complexity of the machines is kept low by the corresponding holding devices, suction cups are attached to frames that are attached to existing pivoting axes of the machine, so that the costs are kept low.

Further embodiments are specified in the dependent claims.

DESCRIPTION OF PREFERRED EMBODIMENTS

the 1 shows a perspective view of a processing machine 1 according to exemplary embodiments of the invention. More precisely of two sections of one Processing machine 1 with its upper parts 3 and lower parts 2, which are arranged on a transverse frame 4. Processing machines 1 with four, six or 8 sections are customary, in which case a feeding and turning unit 50 is particularly advantageous due to the length and weight of the flat component 5 to be turned. The frame 4 runs in a direction of the double arrow 7, which direction is also the direction of the bending edges that can be produced with the processing machine 1. This direction runs transversely to the feed direction 17.

The one in the 1 The section shown furthest to the left is the foremost section in front of a set-up area 20. Here, a lay-on unit 70 is shown in the form of a side-insertion unit, which is associated with FIG Figures 13 to 22 is explained. This placement unit 70 is used together with a transfer table 80 with stops 12 .

The upper part 3 is also referred to as the upper machine part and the lower part 2 as the lower machine part of such a sheet metal bending machine. These are arranged so as to be movable relative to one another perpendicularly to a feed direction 17 of a workpiece 5 to be bent. A lower holding beam 21 and a lower bending beam, also referred to as the lower machining tool 22, are assigned to the lower machine part, and an upper holding beam 23 and an upper bending beam, also referred to as the upper machining tool 24, are assigned to the upper machine part, with the four cheeks being transverse are aligned with the said feed direction and the flat component 5 to be bent can be inserted between the said four cheeks between the machine parts, with the upper holding cheek clamping the workpiece to be bent in a clamping position opposite the lower holding cheek, the lower bending cheek being set up in the said clamping position, in order to bend the flat component 5 to be bent upwards around the front edge of the upper holding cheek, with a double bender a further clamping position being set up in such a way that the upper bending cheek 24 can bend the flat component 5 to be bent downwards around the front edge of the lower holding cheek 21.

The upper parts 3 and lower parts 2 can be driven and articulated in many ways, especially after EP 3 403 738 A1 the applicant. The processing machine 1 also does not have to be a double bending unit that has a lower processing tool 22 and an upper processing tool 24, as here in 1 shown, has. It can also be a single editing tool, with this is assigned to the feeding and turning unit 50 as a loading unit. the Figures 2 to 12 show here a double bender with two placement units 50 and 60, which are assigned to the two processing tools 22 and 24.

The feed unit 50 comprises a series of suction cups 51 connected to a pneumatically operated vacuum source, this connection being controlled, for example, via hydraulically activatable valves. The feed unit 50 or the suction cups 51 of this are attached to a frame component 53 to which the processing tool 24 is attached directly or indirectly. The processing tool 24 is connected via an in 4 shown movable parallelogram mechanism 52 articulated on the upper part 3 and the upper beam 23. In particular - as with the EP 3 403 738 A1 - the processing tool 24 is already arranged in relation to the upper part 3 and the upper beam 23 in such a way that the processing tip of the processing tool 24 is arranged in the extension direction of the infeed table 10, which corresponds to the direction of the plane defined by the surface of the underside of the suction cups 51, which direction in the side view of the 6 is specified by the sheet 5.

the 6 shows the feed unit 50 after the placement of the flat component 5, before it after 7 is placed on the infeed table 10 and is then brought into the machine 1 as a feeding step by retracting the infeed table 10, in order to be advanced in the direction 17 in a predetermined manner after striking the depth stops between sections of the infeed table for processing.

the Figures 2 to 8 show in a sequence the sequence of movements when using this placement unit 50 with its additional function as an upper turning unit. while showing 2 a schematic side view of essential parts of a processing machine 1 with an infeed table 10 and the placement unit 50 in a rest position. The upper part 3 is slightly open compared to the lower part 2.

the 3 shows a schematic side view of the processing machine 1 1 with a pushed-out feed table 10 on which the sheet to be machined or already machined 5 is located. The laying-on unit 50 is in a rest position.

the 4 shows a schematic side view of the processing machine 1 1 with a pushed-out feed table 10 and the loading unit 50 on the Flat material part 5 in a receiving position. The upper processing tool 24 is pivoted as for a hemming process, except that the upper part 3 of the processing machine 1 is slightly open in relation to the lower part. This opening only needs to be opened slightly so that the processing tip of the upper processing tool 24 remains securely above the feed table 10 . In the exemplary embodiment shown, the processing tool 24 is pivoted with the parallelogram mechanism 52 on the holder 53 outside the upper part 3, so that the suction cup 51 shown (from a row of suction cups 51 arranged parallel to the processing tool 24 in direction 7) is placed on the flat material part 5 lowered and supported on this, so that the flat material part 5 adheres to the suction cups 51 by a downstream suction of air located inside the suction cup 51 . A negative pressure is usually generated pneumatically and applied to the suction cups 51 via hydraulically operated valves, which negative pressure is then constantly maintained.

the figure 5 shows a schematic side view of the processing machine 1 1 with a pushed-out feed table 10 and the laying-on unit 50 with picked up flat material part 5, the laying-on unit 50 returning to the rest position. This position of figure 5 is maintained in the vacuum from the 4 achieved by returning the machining tool 24 to its starting position.

the 6 shows a schematic side view of the processing machine 1 with a pushed-out feed table 10 and the loading unit 50 with the feed table 10 lowered flat material part 5. After the flat material part 5 is held by vacuum application on the suction cups 51 and in the position of figure 5 has been included is the application of a negative pressure / vacuum to represent the 6 was reduced via a valve control (lower negative pressure) in such a way that the dead weight of the flat material part 5 made it possible to lower it onto the feed table 10 . The flat material part 5 forms in the side view of 6 with the inward part of the feed table 10 an acute angle in the range between 70 and 85 degrees.

The reference number 54 shows a reinforcement profile, which is arranged on the processing tool in direction 7 depending on the required expenditure of force.

the 7 shows a schematic side view of the processing machine 1 1 with a pushed-out feed table 10 and the placement unit 50 with the flat material part 5 released and sliding onto the feed table 10; just before the flat material part 5 comes to rest fully on the feed table 10 . This movement is ensured by the fact that when picking up the flat material part 5, this has the said slightly acute angle with the feed table in the direction of the interior of the processing machine 1, which is now in the 7 below 30 degrees then changes to 0 degrees (= complete contact).

the 8 shows a schematic side view of the processing machine 1 1 with a partially retracted feed table 10 and now facing it 2 turned flat material part 5. Thus, over the sequence of 2 to 8 a full turn has been achieved. If at the 6 before the flat material part 5 is released by the suction cups, the feed table is drawn in, the flat material part 5 can alternatively also be lowered directly to the ground or to a carriage arranged in front of the processing machine 1 .

the Figures 9 to 12 show in a sequence the sequence of movements when using the placement unit 60, which is designed here as a lower turning unit. while showing 9 a schematic side view of essential parts of a processing machine 1 with an infeed table 10 and the placement units 50 and 60 in a rest position. The upper part 3 is slightly open compared to the lower part 2. The flat component 5 has already been machined on both side ends and has an “S” shape in each case in the cross section shown. An upper lay-up unit 50 and a lower lay-up unit 60 are shown, only the lower lay-up unit 60 being used here in sequence. This is also provided with corresponding suction cups 51 which are mounted on a frame part 53 which is firmly connected to the lower processing tool 22 .

the 10 shows a schematic side view of the processing machine 1 9 with a pushed-out infeed table 10, on which the sheet metal 5, which has already been processed here, lies. The upper lay-up unit 50 is in a rest position and will remain so throughout the sheet 5 turning operation. The turning process is carried out here by a lower placement unit 60 which is attached to the lower processing tool 22 . The lower machining tool 22 as pivoted for a folding process, except that the upper part 3 of the processing machine 1 is slightly open relative to the lower part 2. This opening only needs to be slightly open so that the machined flat component 5 can be safely pushed through on the feed table 10 between the cheeks 21 and 23 . In the exemplary embodiment shown, the lower machining tool 22 is pivoted with the parallelogram mechanism 52 on the holder 53 outside the lower part 2, so that the suction cup 51 shown (from a row of suction cups 51 arranged parallel to the machining tool 22 in direction 7) moves from below the flat material part 5 applies, so that the flat material part 5 adheres to the suction cups 51 by subsequent suction of air located inside the suction cup 51 . The part of the suction cup 51 lying against the flat material part 5 is shown in the side view 10 covered by the feed table 10. The feed table 10 is not a continuous surface, at least here, but has slots in the direction of the double arrow 17 at least at the locations of the suction cups 51, through which it can be applied from below to the flat material part 5 and through which the feed table 10 can be inserted in the direction of this double arrow 17. and is extendable.

the 11 shows a schematic side view of the processing machine 1 9 with a retracted feed table 10 and the laying-on unit 60 with the flat material part 5 that has been picked up and carried by it, before the laying-on unit 60 returns to the rest position. The one in the 11 The illustrated end position of the parallelogram mechanism 52 goes beyond the fold position of the lower processing tool 22 and also leads beyond the horizontal as alignment of the front end face of the suction cups 51. Therefore, the free edge of the flat component 5 pointing away from the processing machine 1 (as far as the main orientation of the flat component 5 is concerned) is arranged higher relative to the base of the processing machine 1 than the end of the flat component 5 near the suction cup.

the 12 shows a schematic side view of the processing machine 1 9 with the previously swung out lower loading unit 60 in the rest position but with activated suction cups 51 with it still held flat material part 5 over a shelf 11. From the 11 Starting from this, the lower placement unit 60 is pivoted back so that the lower retaining cheek 21 forms the lower edge opposite the upper retaining cheek 23 and the flat material part 5 held on the suction cups 51 is pivoted downwards.

It is possible, but not in 12 shown that the plane defined by the main plane of the flat material part 5 is similar to the flat material part 5 in FIG 6 is aligned. Then, when the suction cups are no longer held under vacuum, the sheet 5 falls on its back and the two "S" folds projecting upwards remain up. The flat material part 5 then falls onto the tray 11 without having been turned beforehand. The advantage then lies in the fact that, particularly in the case of very long metal sheets that extend in the transverse direction 7 over six or eight sections, the flat material part 5 only falls from a small height, making the risk of accidents and damage to the component less likely.

In a solution of the suction cups 51 only in the position of 12 the lower placement unit 60 acts as a turning unit and turns the flat material part 5 in relation to its position in, for example 9 and then places it on shelf 11.

Similar to the execution 6 However, the lower placement unit can also be designed as a feed unit when in the position of the 12 the (then still unprocessed) flat component 5 is pressed against the row of suction cups and then the suction cups 51 with their parallelogram mechanism backwards, so to speak 11 be moved in order to then first correctly position the flat component for the folding processes described above after the feed table 12 has been pushed underneath.

The arrangement of the lower and upper placement units 50 and 60 is fixed to the associated bending tools 24 or 22 or on an axis parallel to their pivoting axis, which is also an axis parallel to the axis of movement of the upper part 3 (and if the lower part 2 is pivotable) or parallel to the axis of movement of the lower part 3 allows faster and safer turning of the flat component or faster conveyance of the same from the bending machine. Because these units act outside of the upper part 3 and lower part 2, this does not need to be opened that far, which saves further time. Due to the arrangement of the superimposed holding cheeks and processing tools 21, 22 and 23, 24, which is not necessary for the initial advantages of this laying unit 50 or 60, the angular relationships for the turning units 50 and 60 are easy to achieve an angle of over 90 degrees for effective turning is easier and can be achieved by using the parallelogram mechanism 52 that is already present for bending, which means one movement axis less.

the 13 shows a perspective view with essential parts of a processing machine 1 according to an embodiment of the invention. The feed table 10 is in the retracted position between the upper part 3 and the lower part 2, only a section of which is shown here. This section shown is the foremost section in front of a set-up area 20, which has a transfer table 80, not shown here. A loading unit runs transversely between the upper part 3 and the lower part 2 as a side insertion unit 70 which has a side insertion rail 72 under which a frame component 73 is arranged such that it can be moved in direction 7 . A plurality of suction cups 51, here nine in a 3×3 matrix, are arranged on the frame component 73, with which a flat component 5 can be picked up laterally outside of the processing machine 1 by the set-up table 80 mentioned. It has already happened here. The suction cups 51 correspond to the suction cups of the other exemplary embodiment with a corresponding, advantageously hydraulic control of valves and a permanently operated vacuum source.

The frame component 73 and thus the side insertion rail 72 is firmly connected to the upper part 3 . This leads in particular to a saving on an axis to be moved, since the flat component 5 can be lifted by the suction cups 51 of the side insertion unit 70 simply by opening it slightly (and thus tilting the rail 72. In order to be able to easily see the correct position of the A fixed transfer table 80 with stops 12 is provided to achieve flat component 5 for insertion into processing machine 1. These stops are in FIGS 1 , 19 and 21 only shown arranged forward. Lateral stops are not necessary since the position of the flat component 5 in the direction of the arrow 7 is not critical, because the cutting length of the bending machine 1 always far exceeds the length of the flat component 5 .

the 14 shows a schematic side view of the processing machine 1 13 with the placement unit 70 in the pickup position with nine activated suction cups 51 with the flat component 5 picked up. 15 shows a schematic side view of the processing machine 1 13 with the placement unit in the insertion movement of the recorded flat component 5, the upper part 3 being slightly open, so that the flat component 5 is slightly inclined relative to the loading table 10. the 15 shows the insertion movement so that it is a state timed after the 14 indicates. It's with her too 16 to recognize the a perspective view of the situation of 15 with the retracting placement unit 70, the flat component 5 that has been sucked in being moved in the direction of the double arrow 7 (here to the right) by the suction cups 51 and being moved further.

When picking up the flat component 5 in 14 the upper part 3 of the processing machine 1 is slightly closed, ie towards the lower beam 21 but not for clamping, but for docking the suction cups 51 on the flat component 5. This makes it clear, and that is later in the 20 shown that the transfer table 80 is arranged parallel to the feed table 10 but higher with respect to the horizontal. After the in the 14 After the flat component 5 has been sucked in as shown and has taken place, the upper part is opened slightly, whereby the insertion rail is raised and tilted about the same axis of rotation, so that the flat component 5 picked up is lifted from the transfer table 80 and then moved by the frame component 73 along the side insertion rail 72 in the insertion direction of the double arrow 7 , until well after the presentation of the 16 the entire flat component 5 has been moved into the processing machine 1 until it is positioned between the cheeks 21 and 22 .

the 17 shows a schematic side view of the processing machine 1 13 with the placement unit 70 after releasing the suction cups 51 with the flat component 5 lowered, whereby this protrudes from the front of the machine 1. For this shows 18 a perspective view of the situation of the processing machine 1 chronologically 17 , wherein the frame component 73 has been pulled back laterally on the side insertion rail 72 of the placement unit 70, while the metal sheet between the cheeks 22, 24 protrudes from the machine 1 at the front. 20 shows a schematic side view of the processing machine 1 19 .

This Figures 17 to 20 show that after releasing the flat component 5, the flat component 5 can be advanced with precise positioning without the use of the feed table 10 by depth stops (not shown here), which are located between segments of the feed table 10 divided in the direction of the double arrow, in order to then fold the flat component 5 allow. For the frame member 73 is moved out laterally, as the 18 indicates. the 19 shows the position of the frame component 73 to the side next to the foremost section of the processing machine 1, but in the direction of the double arrow 7 behind the transfer table 80, i.e. in a free space between this and the section of the processing machine 1, so that the frame component 73 can be moved when the upper part 3 can move freely up to a clamping position, without to be impeded by the transfer table 80 or by a next flat component 5 that has already been placed on it. At the same time, this addresses the time-advantageous simultaneous renewed loading of the machine 1 on the transfer table 80 while the processing steps of clamping and folding are still ongoing.

21 shows a perspective view of the machine 1 during a folding process of a first flat component 5, the side insertion unit being the placement unit 70 in the parking position and a second flat component being placed on the transfer table 80 and pushed against the stops 12; and 22 shows a schematic side view of the processing machine 21 with the laying unit 70 in the parking position, with the two flat members 5, one which is bent over in its front portion and the other which lies on the transfer table 80.
