Description

[0001] The invention relates to a method for separating at least one workpiece from a residual skeleton of parts as well as a vibration device and a separating device, in particular for carrying out the method.

[0002] EP 2 436 474 B1 discloses a mechanical arrangement for separating at least one workpiece from a sheet-like material by cutting in a machine tool. A composite of residual skeleton parts produced after cutting the sheet-like material is removed by a handling device and placed on a conveyor belt. The conveyor belt is then driven, so that the composite of residual skeleton parts is guided out of the handling device and transferred to an unloading conveyor belt. Subsequently, manual sorting of the workpieces from the residual skeleton or sorting assisted by a handling device, in particular a robot, can be provided.

[0003] JP 63260692 A1 discloses a separating device for separating a web connection between a workpiece and a scrap skeleton. A sheet produced by cutting is transferred from an upper position onto a conveyor belt by free fall. This conveyor belt is then subjected to vertical vibrations. Some of the workpieces are sorted downwards. The scrap skeleton is then removed from this separating device.

[0004] A workpiece transport device for laser-cut sheet material is known from CN 215509540 U. Vibrations applied to the conveyor belt separate the workpiece from the scrap skeleton and allow it to fall into a parts container positioned below the conveyor belt.

[0005] US Pat. No. 5,259,107 A discloses a separating device for separating a web connection between a workpiece and a scrap skeleton. A tool is provided, which is fed onto the plate-shaped scrap skeleton assembly from a top and a bottom side. The web connection is separated by tapping or hammering by the two opposing tools.

[0006] The invention is based on the object of proposing a method for separating at least one workpiece from a residual skeleton part assembly, by means of which a rapid and reliable separation of cut workpieces that are connected to the residual skeleton by a web connection is enabled. Furthermore, the invention is based on the object of proposing a vibration device by means of which a rapid and reliable separation of a web connection by which the workpiece is held to the residual skeleton is enabled. Furthermore, the invention is based on the object of proposing a separating device for separating at least one workpiece from a residual skeleton, which enables a rapid and reliable separation of the workpiece connected to the residual skeleton by a web connection.

[0007] The object underlying the invention is achieved by a method for separating at least one workpiece from a residual skeleton assembly, in which the residual skeleton assembly is guided out of the machine tool and the residual skeleton assembly is fed to a separating device which comprises a conveyor with a conveyor means, by means of which the residual skeleton assembly is moved along a transport direction and in which a vibration device is moved from a rest position above the conveyor means into a working position and placed on the residual skeleton assembly and the vibration device is activated in the working position. This method enables the vibration device provided on the upper side of the residual skeleton assembly to specifically introduce vibrations into the residual skeleton assembly, by means of which vibrations a web connection between the workpiece and the residual skeleton is severed.

[0008] Preferably, the rebar assembly is moved intermittently along a conveyor path with the conveyor in the separating device. During a standstill phase between the intermittent transport, the vibration device is placed on the rebar assembly and activated. This intermittent transport of the rebar assembly has the advantage that the vibrations only affect certain areas of the rebar assembly. This allows for a reduction in the operating time of the vibration device. The length of the intermittent travel path can be selected depending on the intensity of the vibrations introduced by the vibration device.

[0009] Furthermore, it is preferably provided that the cyclically traveled distance of the remnant skeleton assembly is at least half the length of the remnant skeleton assembly, preferably at least 1 / 4 of the length of the remnant skeleton assembly. This cyclically traveled distance also depends on the size and / or number of workpieces in the remnant skeleton that are connected to the web. For example, a remnant skeleton assembly that has a length of, for example, 3 m can be subjected to vibrations from the vibration device every 0.5 m.

[0010] Preferably, the web connection between the at least one workpiece and the residual skeleton is severed by the vibration device, with a web connection being provided particularly for workpieces that are configured as small parts, micro-parts, or tilting parts. These small parts, micro-parts, or tilting parts have a size that is, for example, smaller than a transfer gap between the conveyor means of the separating device and, viewed in the transport direction, an upstream conveyor belt in the handling device.

[0011] According to a preferred embodiment of the method, the residual skeleton assembly is fed with a partial section to the separating device and subsequently the web connection of the at least one workpiece to the residual skeleton is severed by the vibration device and during a subsequent travel path a further partial section of the residual skeleton assembly is introduced into the separating device, wherein the previously separated workpieces fall downwards between conveyor belts of the conveying means and are absorbed in a parts container and at least the residual skeleton is guided out of the separating device and transferred to an unloading conveyor belt. The residual skeleton lying on the unloading conveyor belt, which may still contain freely cut, large workpieces which could not be sorted out downwards due to their format, is unloaded manually or by means of a handling device.

[0012] According to an alternative embodiment of the method, it is provided that after the residual skeleton assembly has been removed from the machine tool, the residual skeleton assembly is fed to an unloading station with a handling device for large workpieces which are completely cut free from the residual skeleton, and the large freely cut workpieces are removed automatically, and then the remaining residual skeleton assembly is fed to the separating device for separating the at least one workpiece which is connected to the residual skeleton by a web connection, and after the web connection has been separated, the small part, preferably with a dimension of less than 150 mm or a micro part, preferably with a dimension of less than 60 mm orThe workpiece formed as a tilting part is conveyed downwards into a parts container through the conveyor, and the residual skeleton is removed from the separating device and fed into a subsequent waste container. Advantageously, the residual skeleton can also be divided into small-format residual skeleton sections by one or more web connections, so that after being removed from the separating device, small-format residual skeleton sections can be transferred into the waste container.

[0013] The object underlying the invention is further achieved by a vibration device, in particular for separating the at least one workpiece from the residual skeleton composite, which comprises a holding bar on which at least one vibration head is provided. Such a holding bar can accommodate one or more vibration heads. This holding bar can be mounted, for example, on a base body of a separating device above a conveyor. Likewise, this holding bar can also be mounted on a linear axis system assigned to the separating device.

[0014] Advantageously, the retaining bar extends at least along the width of a conveyor of the conveyor system. This allows the at least one vibration head provided thereon to be moved into different positions along the entire length of the retaining bar. This allows the vibrations to be introduced into individual areas of the residual skeleton assembly in a specific application.

[0015] It is preferably provided that the at least one vibration head is movable or displaceable along the holding strip and preferably the at least one vibration head is adjustable to a working position for introducing the vibrations into the residual skeleton assembly. In particular, two or more vibration heads can be adjusted and aligned at a distance from one another. As a result, viewed along a width of the residual skeleton assembly, for example, several smaller workpieces can be provided next to one another, which are held in the residual skeleton by a web connection, and adjacent to these, larger workpieces that are cut free from the residual skeleton. In such a residual skeleton assembly, the vibration heads are adjusted such that they are assigned to the small workpieces with the respective plug-in connection.

[0016] According to an alternative embodiment of the vibration device, at least two spaced-apart vibration heads are provided on the retaining bar, which accommodate a vibration bar that extends at least partially across the width of the conveyor. Advantageously, the vibration bar extends across the entire width of the conveyor. This allows for a virtually continuous vibration head to be created.

[0017] The at least one vibration head of the vibration device can be pneumatic, hydraulic, or electrical or driven by a further vibration excitation.

[0018] The vibration heads provided on the holding bar can advantageously be controlled individually. This allows, for example, a different number and / or sequence of vibration heads to be controlled according to a particular cyclical movement of the skeleton part assembly. For example, the vibration heads can also be controlled in groups or all at once.

[0019] The object underlying the invention is further achieved by a separating device for separating at least one workpiece from a residual skeleton of a residual skeleton assembly, which comprises a base frame receiving a conveyor device, wherein the conveyor device has a conveyor by which the residual skeleton assembly is received on the inlet side and can be transported in the transport direction, wherein a vibration device according to one of the previously described embodiments is provided above the conveyor means, which can be transferred at least temporarily from a rest position to a working position and can be placed on the residual skeleton assembly, and the vibration device can be activated in the working position and causes the residual skeleton assembly to vibrate. By means of such a separating device, the vibrations can be introduced directly into the residual skeleton assembly with the vibration device.This enables a quick and reliable separation of the web connection between the workpiece and the remaining skeleton. Oscillations also include vibrations or shaking movements.

[0020] In the separating device, the vibration device is preferably provided on the inlet side of the conveyor. Alternatively, the vibration device can also be provided in a region between the beginning of the conveyor and halfway along the conveyor's conveying path.

[0021] Furthermore, it is preferably provided that the holding bar of the vibration device is adjustable at a distance from the transport plane of the conveyor. This allows different thicknesses of the residual skeleton assembly to be processed and the web connections of the workpieces to be separated. Alternatively, it can be provided that the respective thickness of the residual skeleton assembly is taken into account when controlling the movement of the vibration device from the rest position to the working position.

[0022] According to another embodiment, the conveyor is formed by support bars or support webs that are aligned transversely to the conveyor. These support bars have support tips on which the residual skeleton assembly rests.

[0023] According to an alternative embodiment of the conveyor, it is provided that it is formed from several conveyor belts aligned in the conveying direction. These conveyor belts are narrow in relation to the width of the conveyor. Advantageously, the distance between these conveyor belts is adjustable. Thus, a free space is provided between the conveyor belts through which the workpieces, in particular small parts, micro-parts, or tiltable parts, can fall.

[0024] Preferably, at least one parts container is positioned below the conveyor system. This allows workpieces for which the plug connection to the scrap skeleton has been severed and whose width is smaller than the distance between two adjacent conveyor belts to be sorted downwards. It can also be provided, for example, that two or three conveyor belts are positioned at a smaller distance and at least two additional conveyor belts are positioned at a larger distance. In this case, two parts containers are positioned below the conveyor system, enabling pre-sorting of the smaller and larger workpieces.

[0025] According to a further preferred embodiment of the separating device, a hold-down element is provided above the conveyor, which is preferably height-adjustable and / or movable up and down perpendicular to the transport plane of the conveyor. Such a hold-down element rests on the upper side of the residual skeleton component assembly at least when vibrations are introduced into the residual skeleton component assembly by the vibration device. This has the advantage that a workpiece removed from the residual skeleton due to the vibrations does not come to rest on the upper side of the residual skeleton. Because the hold-down element rests on the residual skeleton component assembly, the workpiece remains in the residual skeleton after the web connection has been broken. This can enable a further increase in process reliability. In particular, the hold-down element extends below the vibration device.Thus, the vibration is introduced into the residual skeleton part assembly via the hold-down element.

[0026] A further preferred embodiment of the separating device provides for a scraper, in particular a brush strip, to be provided on the inlet and / or outlet side of the conveyor, which is preferably adjustable in height relative to the transport plane. If no hold-down element is provided or if a workpiece nevertheless comes to rest above the scrap skeleton, the workpiece resting on top is retained when the scrap skeleton is removed from the separating device and can then also be removed from the separating device after the scrap skeleton has been removed. This, in turn, ensures process reliability for the downstream sorting process.Furthermore, the stripper provided on the inlet side has the advantage that a preceding workpiece may come to rest above the skeleton, preventing the workpieces resting on the skeleton from being damaged by a vibration head when moving into the separating device. Preferably, an additional collecting container is assigned to the separating device below the stripper on the inlet side. The at least one stripper is preferably height-adjustable, which in turn allows adaptation to the thickness of the skeleton-part composite to be processed.

[0027] The invention, as well as further advantageous embodiments and developments thereof, are described and explained in more detail below with reference to the examples shown in the drawings. The features shown in the description and the drawings can be used individually or in any combination according to the invention. They show: Fig. 1 a mechanical arrangement for laser cutting plate-shaped workpieces with a laser cutting machine and an automation unit arranged in front of it with a handling device and a cutting device, Fig. 2 a schematic side view of the separating device according to Fig. 1, Fig. 3 a schematic view from the front of the separating device according to Fig. 1, Fig. 4 a perspective view of a vibration device of the separating device, Fig. 5 a perspective view of an alternative embodiment of the vibration device Fig. 4, and Fig. 6 is a schematic top view of an alternative embodiment of a machine arrangement for Fig. 1.

[0028] In Fig. Figure 1 shows a perspective view of a machine assembly 1 with a machine tool 3, in which a sheet-like material 2 is separated by a cutting device into at least one workpiece 7 and a residual skeleton 8 or several residual skeleton parts. The machine tool 3 is preferably designed as a laser cutting machine.

[0029] For cutting, the plate-shaped material 2, in particular the sheet metal, is placed on a workpiece support 15 inside a working area 5 of the machine tool 3. In a known manner, the plate-shaped material 2 is passed over by a laser cutting head 6 of the laser cutting machine for cutting. Fig. 1 shows a plate-shaped material 2 inside the work area after cutting, during which workpiece blanks or workpieces 7 in the form of finished parts and a residual skeleton 8 at least partially surrounding the workpiece 7 were produced as processing products. Between the workpiece 7 and the residual skeleton 8 there is a cutting gap a few millimeters wide. The at least one cut workpiece 7 and the residual skeleton 8 form a residual skeleton part assembly 9. It is preferably provided that a large-format workpiece 7' is completely cut free from the residual skeleton 8. A workpiece 7, which is a small part, a very small part and / or a tilting part, is connected and held in the residual skeleton 8 by at least one web section or a plug-in connection, in particular a microjoint or nanojoint.

[0030] The workpiece support 15 is provided on a movable pallet 4, which was moved with the sheet material 2 through a slot-shaped opening in a housing of the machine tool 3 into its working area 5. Previously, the workpiece support 15 with the raw sheet material 2 was placed on the front side of the machine tool 3 on a conventional pallet changer 10. After the sheet material 2 has been machined, the pallet 4 with the workpiece support 15 is moved back onto the pallet changer 10 with the residual skeleton assembly 9 resting thereon. From the pallet changer 10, the residual skeleton assembly 9 is removed jointly by a handling device 11 of an automation unit 12.

[0031] The handling device 11 is motor-driven and can be moved in the direction of a double arrow 14 on a linear device 13 of the automation unit 12. The handling device 11 can be moved either via the pallet changer 10 or via a conveyor belt 19 arranged laterally next to the pallet changer 10. A separating device 21 is provided adjacent to the conveyor belt 19. The residual skeleton part assembly 9 is guided out of the handling device 11 via the conveyor belt 19. To increase the degree of automation, the separating device 21 is provided adjacent to the conveyor belt 19. A discharging device, in particular an discharging conveyor belt 23, is arranged downstream of the separating device 21 in the transport direction 22, for example.

[0032] In the separating device 21, the web connection between the workpiece 7 and the scrap skeleton 8 is severed by the vibration device 25. The separated workpiece(s) 7 are sorted out as they fall downwards within the separating device 21. The scrap skeleton 8, as well as any large-format workpieces still remaining in the scrap skeleton, are guided out of the separating device 21 and fed to the unloading conveyor belt 23. At the end of the unloading conveyor belt 23, the remaining workpieces 7' can be unloaded manually or using a handling device 39. The scrap skeleton can be placed on another pallet, which is arranged, for example, for movement below the unloading conveyor belt 23. The scrap skeleton 8 can also be unloaded using the handling device 39.

[0033] In Fig. 2 shows a schematic side view of the separating device 21. The Fig. Figure 3 shows a schematic front view. This separating device 21 is designed as a standalone module or unit. It can be integrated between the conveyor belt 19 and the unloading conveyor belt 23. The separating device 21, arranged between the conveyor belt 19 and the unloading conveyor belt 23, is positioned so as to be vibration-decoupled from the conveyor belt 19 on the one hand and the unloading conveyor belt 23 on the other.

[0034] This separating device 21 comprises a base frame 26. This base frame 26 accommodates a conveyor device 27 with a conveyor 28. A rest skeleton assembly 9 resting thereon is transported in the transport direction 22 by the conveyor 28. The vibration device 25 is positioned above the conveyor 28. Advantageously, the vibration device 25 is attached to a frame 29 of the base frame 26.

[0035] The vibration device 25 is preferably assigned to the inlet side of the conveyor device 27. This vibration device 25 is adjustable at least in height relative to the transport plane of the conveyor 28. The conveyor 28 comprises a plurality of conveyor belts 30 aligned in the transport direction 22. These conveyor belts 30 are designed to be many times narrower than the width of the conveyor 28. Each conveyor belt 30 is preferably adjustable in its distance from the adjacent conveyor belt 30. Each conveyor belt 30 is advantageously driven individually. At least one parts container 31 is provided below the conveyor 28. This parts container can be positioned on a transport carriage 32 or on a pallet. Workpieces 7 that may fall between the conveyor belts 30 are caught in this parts container 31.

[0036] The separating device 21 can have a stripper 33 on the inlet side and / or the outlet side. On the inlet side, the stripper 33 is positioned in front of the vibration device 25, as seen in the transport direction 22. On the outlet side, the stripper 33 is positioned at the end of the conveyor belts 30. The inlet-side stripper 33 serves to prevent any workpieces 7 or waste pieces from internal contours resting on the scrap skeleton 8 from entering the separating device 21. The outlet-side stripper 33 serves to ensure that a scrap skeleton, possibly containing large-format workpieces, is removed from the separating device 21 without a workpiece 7 resting on top, so that subsequent, process-reliable unloading from the unloading conveyor belt 23 is possible.

[0037] In Fig. 4 shows a perspective view of the separating device 21. The vibration device 25 advantageously extends across the entire width of the conveyor 28. In this embodiment, a holding bar 36 extends between the frame 29. At least one vibration head 37 is provided on the holding bar 36. Preferably, several vibration heads 37 are arranged on the holding bar 36. These vibration heads 37 can advantageously each be controlled or activated individually. These generate vibrations, oscillations or shaking. Preferably, the vibration heads 37 can be moved from a rest position into a working position in which the vibration heads 37 rest on the residual skeleton part assembly 9. In this working position, the vibration heads 37 are activated so that vibrations are introduced into the residual skeleton part assembly 9 in order to break the at least one web connection.

[0038] In Fig. 5 is a perspective view of an alternative embodiment of the vibration device 25 to Fig. 4. In this embodiment, two vibration heads 37 arranged at a distance from one another are provided on the holding bar 36. These vibration heads 37 accommodate a vibration bar 38. This vibration bar 38 can extend partially across the width of the conveyor 28. In such a case, two or three vibration bars 38 can also be provided in series, one behind the other. Advantageously, the vibration bar 38 extends across the entire width of the conveyor 28. To break the web connections, this vibration bar 38 is placed on the residual skeleton part assembly 9.

[0039] The prescribed separating device 21 operates as follows: A skeleton assembly 9 resting on the conveyor belt 19 is fed cyclically to the separating device 21. During the feed movement, the vibration device 25 is in a rest position, i.e., raised relative to the transport plane of the conveyor 28. The skeleton assembly 9 is conveyed into the separating device 21 along a predetermined travel distance. The travel movement is then stopped. The vibration device 25 is moved into a working position in which the vibration heads 37 touch the skeleton assembly 9. The vibration heads 37 are activated. The vibrations introduced into the skeleton assembly 9 separate at least one web connection between the workpiece 7 and the skeleton 8. The skeleton assembly 9 is then conveyed into the separating device 21 by a further predetermined travel distance in the transport direction 22.The workpieces 7 that have been separated in the meantime and are smaller than the distance between the conveyor belts 30 can be sorted downwards and collected in the parts container 31. Subsequently, the skeleton-part assembly is stopped again, and the vibration device 25 is activated. This process can be repeated several times depending on the predetermined travel distance on the one hand and the length of the skeleton-part assembly 9 on the other. Subsequently, the skeleton 8 and any large-format workpieces remaining in the skeleton 8 are removed from the separating device 21 and transferred to the unloading conveyor belt 23.

[0040] In Fig. 6 is a schematic view of an alternative embodiment of a machine arrangement 1 to Fig.1. In this embodiment, it is provided that, for example, on one side of the machine tool 3, a loading station (not shown) is provided in order to feed unprocessed plate-shaped material or partially processed plate-shaped material 2 to the machine tool 3. On the opposite side of the machine tool 3, a conveyor device 27 is provided, by means of which a residual skeleton part assembly 9 is guided out of the machine tool 3. In this embodiment, it is provided, for example, that the conveyor means 28 is formed from support webs or support strips. These support strips are arranged at a fixed distance from one another. This conveyor device 27 can extend into the machine tool 3. A handling device 39 is assigned to this conveyor device 27.This handling device 39 allows large-format workpieces 7', which have been completely cut free from the scrap skeleton 8, to be unloaded and placed, for example, on a pallet or the like. The remaining scrap skeleton assembly 9, which consists of a scrap skeleton 8 and at least one workpiece 7 held by a plug connection to the scrap skeleton 8, is subsequently fed to the separating device 21. The operation of the separating device 21 corresponds to the operation described above. In this exemplary embodiment, only the scrap skeleton 8 is fed out of the separating device 21 and placed in a collecting container 41. The scrap skeleton 8 is preferably cut into several parts that are connected by a web connection.This web connection of the residual skeleton parts is also separated in the separating device 21, so that small-sized waste parts of the residual skeleton 8 are subsequently deposited in the collecting container 41.
