Definitions
- the present invention relates to a method for the spatial arrangement of coils in a coil store and a combination of a processing machine and a coil store.
- a coil in the sense of the present application is understood to mean a sheet metal reel, i.e. a reel on which sheet metal in the form of sheet material is wound.
- the processing machine can be, for example, a sheet metal cutting machine, a sheet metal bending machine, a sheet metal punching machine or some other sheet metal processing machine.
- Sheet metal processing companies usually process various types of orders from their customers.
- the various jobs regularly require the processing of sheets of different thicknesses and / or different material compositions.
- the individual orders are usually never so extensive that the entire sheet metal wound in the form of a coil with a certain thickness and / or composition is processed by the processing machine in one operation. Rather, depending on the job, the processing machine has to be fed one type of sheet metal for processing, and then the other.
- a well-known coil store is, for example, in the EP 1 626 823 B1 described.
- Fixed bearing blocks are proposed there for storing the coils in fixed storage locations.
- the fixed storage locations mean that the coils located in the coil store, regardless of how much sheet metal has already been withdrawn from the individual coils for processing, have an essentially constant space requirement over the service life of the processing machine.
- the increasing variety of sheet thicknesses and types of sheet to be processed in practice means that more storage space must be made available for the coil store if sheet thicknesses or types of sheet are to be processed that are not yet available in the coil store.
- first rails are provided for transporting the coils from a starting point to an end point with a transport carriage and second rails are provided for transporting the coils from the end point back to the starting point by means of the same transport carriage.
- second rails are arranged above the first rails. With the help of lifting and lowering devices, the trolley can be moved vertically between the plane of the first rails and the plane of the second rails.
- the processing machine precisely that coil with the sheet metal to be processed (selected coil) is transported to the processing machine. A part of the sheet metal is then unwound or unwound from the selected coil and processed in the processing machine. The selected coil is then transported back to the coil store, where it waits for the next order, which requires exactly the sheet metal of this selected coil for processing.
- the diameter, more precisely the outer diameter, of all coils in the coil store decrease sooner or later to a greater or lesser extent as sheet metal processing progresses.
- the inventive method uses in a skilful manner the thereby between The individual coils are increasingly free space as a storage space for coil storage.
- the method according to the invention is carried out with the aid of an electronic, programmed system control.
- the initial diameters of all coils, which may differ in size, and the spatial coordinates of the initial storage positions of all coils in the coil store are stored in it.
- the initial storage positions can be stored, for example, in the form of the respective spatial coordinate of the coil axis of each coil.
- the sheet metal of the selected coil If there is an order to process the sheet metal of the selected coil, it is transported to the processing machine and part of its sheet metal is processed.
- the reduced diameter of the selected coil is detected electronically by the system control with the aid of a sensor, preferably an optical laser sensor.
- the system control calculates a storage storage position that deviates from the initial storage position, with the reduced diameter of the coil being included in the calculation of the storage storage position. Due to the reduced diameter of the selected coil, its coil axis can be arranged closer to the coil axis of an adjacent coil.
- This approach of the selected coil with reduced diameter to an adjacent coil takes place, for example, in such a way that the coil axis of the selected coil is offset by half the reduction in its diameter from its initial storage position in the direction of the adjacent coil.
- the distance between the cylindrical outer surfaces of the offset, selected coil and the one adjacent to it is then Coils as big as they were when the selected coil still had its larger initial diameter and was still in its initial storage position.
- the coil selected and transported back into the coil store moves spatially preferably in the direction of the processing machine in the row of coils located in the coil store.
- the electronic system control can save the reduced diameter of the selected coil and the spatial coordinates of the storage location as the new initial storage status in terms of method step a).
- the next cycle of steps b) to f) of the method according to the invention can then be carried out.
- a cycle according to steps b) to f) takes place repeatedly, so that the stored coils move closer or closer together in the coil store.
- an additional coil in the coil store which remains the same in terms of its external spatial dimensions, this can also be added to the coil store.
- the coil store then takes one more coil than it had taken in the original initial storage condition.
- the additional coil can, in particular, be made of a sheet metal whose sheet thickness and / or sheet type was not yet available in the original initial storage condition.
- the transport according to steps b) and e) takes place by means of a coil transport device, which is preferably a coil lifting device.
- a coil transport device which is preferably a coil lifting device. This lifts the selected coil over the coils remaining in the store, transports them in translation to the processing machine and finally unwinds the part of the sheet metal to be processed by the processing machine from the selected coil.
- the latter is particularly advantageous since no separate unwinding device has to be arranged in the area of the processing machine to which the selected coil would have to be transferred.
- the coil transport device which also takes on the function of unwinding, thus avoids a mechanical transfer step of the coil to be unwound and thus the associated risk of malfunctions during a transfer process.
- a device in the form of a combination of a processing machine and a coil store for holding several coils ready for processing the sheet metal of the coils by means of the processing machine comprises a receiving device arranged in the coil store for the storage of all coils at any point on the receiving device.
- a receiving device arranged in the coil store for the storage of all coils at any point on the receiving device.
- an electronic storage device in which electronic data about an initial storage status can be stored, these data containing information about a respective initial diameter of the coils and a respective spatial initial storage position of the coils in the coil store.
- the initial spatial storage position is stored, for example, in the form of the spatial coordinates of the coil axis of each coil.
- a coil transport device transports a selected coil from its initial storage position at a first location of the receiving device to the processing machine for processing part of the sheet metal of the selected coil. Thereafter, the selected coil has a reduced diameter, more precisely the outer diameter.
- the coil transport device can also transport the selected coil having the reduced diameter to a second location of the receiving device which forms a deposit storage position and which deviates from the first location of the receiving device and is controlled by the electronic system control depending on the reduced diameter of the selected coil in a way that saves storage space is chosen that the distance between a coil axis of the selected coil and a coil axis of the selected Coil in the coil storage adjacent coils in the storage storage position is smaller than in the initial storage position.
- a sensor device for detecting the reduced diameter of the selected coil, the detection of the reduced diameter taking place after the part of the sheet metal of the selected coil has been removed from the selected coil for processing by the processing machine.
- the sensor device is preferably an optical laser sensor which is in electronic signal connection with the system control.
- the coil transport device advantageously has an unwinding device for unwinding the part of the sheet metal of the selected coil to be processed in the direction of the processing machine.
- the receiving device for the storage of all coils preferably comprises two elongated bearing supports, each of which has a horizontally extending, elongated upper edge.
- the bearing supports are spaced from one another in such a way that all coils can be held ready at any point on the two horizontal upper edges with the help of stub axles protruding from their end faces or, alternatively, with the help of two bolts attached to the coil transport device, which can engage in bearing shields on the reels of the coils the processing machine can be put down.
- These arbitrary points along the upper edges form a geometrically continuous multitude of storage points at which the coils can be deposited.
- the sensor device for detecting the reduced diameter of the selected coil is advantageously arranged on the coil transport device.
- FIG. 1 an embodiment of a coil store 7 and a processing machine 8 for processing the sheet metal wound in the form of coils 1, 2, 3, 4, 5 and 6 can be seen in a side view.
- the coils 1, 2, 3, 4, 5 and 6 contain rolled up sheet metal with different sheet thicknesses and / or made of different sheet metal compositions.
- the processing machine 8 is, for example, a lengthwise and cross-cutting system for lengthwise and cross-cutting of sheet metal.
- An electronic, programmed system control can be operated by an operator of the processing machine 8 with the aid of an operating unit 15.
- the coil store 7 is located in Fig. 1 in an original initial storage condition in which all six coils 1, 2, 3, 4, 5 and 6 each comprise an original initial quantity of sheet metal. In the embodiment shown, they all have the same initial diameter D A , which is shown in FIG Fig. 1 is only shown as an example for the coil 4. Of course, two, some or all of the coils 1, 2, 3, 4, 5 and 6 can also have different initial diameters in the initial storage state.
- a coil transport device in the form of a portal-like coil lifting device 9 can also be seen, which is shown in FIG Fig. 1 can be moved by motor on running rails 16 from left to right or right to left.
- the coil lifting device 9 can lift a coil in a manner known per se and move it over other coils Fig. 1 move in the horizontal direction.
- An exemplary order of the processing machine 8 is to cut sheet metal with exactly the sheet thickness that is wound on the coil 3.
- the operator has entered this accordingly on the operating unit 15.
- the electronic system control activates the coil lifting device 9 accordingly in such a way that it does the in Fig. 1
- the initial storage position shown for the coil 3 selected for processing the order moves.
- Fig. 1 it can be seen how the coil lifting device 9 has already lifted the selected coil 3 (for illustration purposes only, the coil lifting device 9 together with the lifted coil 3 is shown in FIG Fig. 1 left of the initial storage position of the coil 3).
- the coil lifting device 9 now transports the selected coil 3 in Fig. 1 to the right over coils 4, 5 and 6 until they are in Fig. 2 has reached the unwinding position shown shortly before the processing machine 8. As in Fig. 2 It can be seen that the coil lifting device 9 already has the selected coil 3 lowered into an unwinding position for unwinding the sheet metal into the processing machine 8.
- the starting diameter D A is in Fig. 2 marked on coil 2.
- the coil lifting device 9 is provided with a non-illustrated, known per se unwinding device which the selected coil 3 in Fig. 2 unwinds motor-driven clockwise in such a way that the unwound sheet metal reaches the processing machine 8 for cutting.
- the unwinding device is therefore not arranged in a stationary manner, but always moves with the coil lifting device 9.
- the coil lifting device 9 thus exercises the functions of raising and lowering the coils, of translational transport of the coils in the horizontal direction and of unwinding a coil required in each case on the processing machine 8.
- the coil 3 or 3' is therefore not released by the coil lifting device 9. This is advantageous because no transfer to a stationary unwinding device as in the prior art is required. An associated transfer risk of a mechanical malfunction and the associated transfer time for transferring the coil to the stationary unwinding device are thereby avoided.
- Fig. 3 are that in Fig. 2
- the coil store 7 shown, the processing machine 8 and the coil lifting device 9 can be seen in a view from above.
- Same reference numbers as in Fig. 2 identify the same parts.
- the coil 3 ' After a part of the sheet metal wound on the selected coil 3 has been fed to the processing machine 8 as a sheet metal web and the sheet metal processing order has been processed for the concrete sheet according to coil 3, the coil 3 'has a reduced diameter D compared to its starting diameter D A , which is shown in FIG Fig. 4 is shown.
- the coil 3 'with the reduced diameter D thus takes up less space than the coil 3 with the initial diameter D A.
- the electronic system control is programmed in such a way that it transports the coil 3, 3 'back from its to the Fig. 2 and 3 shown unwinding position with the aid of the coil lifting device 9 in such a way that the coil 3 'is not set down again at its original starting storage position. Instead, the coils 3 'are deposited at a storage position that is in the Fig. 2 and 3 closer to coil 4.
- the coil axis of the coil 3 ' which is again deposited in the coil store 7, is accordingly closer to the coil axis of the coil 4.
- the coil 3' is in comparison to FIG Fig. 2 and 3 one hand and the Fig. 4 on the other hand, moved up a little to the right in the direction of the processing machine 8.
- coil 2 becomes the “selected coil” in the sense of the method according to the invention.
- the coil 2 now also has a reduced diameter and is transported back into the coil store 7 by the coil lifting device 9.
- the storage position of the coil 2 can be calculated by the system control in this case, for example, in such a way that the coil axis of the coil 2 compared to its initial storage position by the sum of half the diameter reduction of the coil 2 and half the diameter reduction of the coil required in the previous sheet metal processing order 3 'in the Figs. 2-4 moves to the right in the direction of coil 3 '.
- Fig. 4 shows the state of the coil store 7 after the execution of a large number of sheet metal processing jobs by the processing machine 8.
- the coils 2 and 6 in this snapshot still have their initial diameter D A , which is shown in FIG Fig. 1 and 2 is shown.
- the coils 1 ', 3', 4 'and 5' have significantly reduced diameters compared to their respective initial diameter D A.
- a reduced diameter D is shown as an example for the selected coil 3 '.
- the coil axis of the coil selected for a processing order moves into the area by the amount of half the diameter reduction that was caused by the unwinding of sheet metal required for processing the order Figs. 1 to 4 to the right.
- This will repeatedly - as in Fig. 4 can be seen - a state reached in which the distances between the cylindrical outer surfaces of adjacent coils are constant.
- the distances between the coil axes of adjacent coils are generally not equidistant, since the coils located in the coil store 7 generally have different diameters.
- the in Fig. 4 The center distance A 4-5 drawn between the coils of coils 4 and 5 is significantly smaller than that in Fig. 4
- the center distance A 5-6 of the coil axes of coils 5 and 6 is drawn.
- Fig. 4 the space gain for storing additional coils can be seen to the left of the coil 1 ', which results from the multiple implementation of the method according to the invention.
- the coil 2 is shown with its initial diameter D A and yet in a storage position moved to the right.
- the system control can be programmed in such a way that a scanner unit present on the coil lifting device 9 is included If required, the geometric state of the coil store 7 can be read electronically into the system control. For a predetermined length of time not required for a processing order coils, here the coil 2, are then in the sense of clearing up the coil store 7 from the coil lifting device 9 to the Fig. 1-4 moved to the right without starting the processing machine 8 with the affected coil.
- two elongated bearing supports 11 and 12 can be seen here in the form of elongated bearing walls. They form the receiving device for the storage of all coils in the coil store 7 in the sense of the present invention.
- the wall-like bearing supports 11 and 12 have horizontally extending upper edges 13 and 14 on which the coils 1, 2, 3, 4, 5 and 6 can be deposited at any point, provided that there is no mechanical collision of the coil to be deposited with others at the corresponding point , coils that have already been stored are to be feared.
- Fig. 5 shows that in Fig. 4 marked detail A in an enlarged view.
- a part of the upper edge 13 of the wall-like bearing support 11 can be clearly seen.
- This rear grip strip 17 can be of a bearing shoe 36, which in Fig. 3 marked stub axle 26 of the coil 6 is supported, are engaged from above.
- the bearing shoe 36 is exemplary for all others in Fig. 3 marked stub axles 21, 22, 23, 24 and 25 of the coils 1, 2, 3, 4 and 5.
- the upper edge 14 of the wall-like bearing support 12 opposite the wall-like bearing support 11 has an in Fig. 5 Not visible rear grip strip, which is designed and arranged analogously to the rear grip strip 13.
- the wall-like bearing supports 11 and 12 run with their upper edges 13 and 14 in a straight line parallel to one another and are spaced apart such that the coil lifting device 9 always places the coils in such a way can that the bearing shoes (see bearing shoe 36 in Fig. 5 ) of coils 1, 2, 3, 4, 5 and 6 the rear grip strips (see rear grip strip 17 in Fig. 5 ) can reach behind along the upper edges 13 and 14 and thereby secure the coils in the axial direction on the bearing supports 11 and 12 in a form-fitting manner.

Description
Die vorliegende Erfindung betrifft ein Verfahren zum räumlichen Anordnen von Coils in einem Coillager sowie eine Kombination aus einer Verarbeitungsmaschine und einem Coillager. Unter einem Coil im Sinne der vorliegenden Anmeldung wird eine Blechhaspel verstanden, d.h. eine Haspel, auf welche Blech in Form von Bahnmaterial aufgewickelt ist. Bei der Verarbeitungsmaschine kann es sich beispielsweise um eine Blechschneidemaschine, eine Blechbiegemaschine, eine Blechstanzmaschine oder eine sonstige Blech verarbeitende Maschine handeln.The present invention relates to a method for the spatial arrangement of coils in a coil store and a combination of a processing machine and a coil store. A coil in the sense of the present application is understood to mean a sheet metal reel, i.e. a reel on which sheet metal in the form of sheet material is wound. The processing machine can be, for example, a sheet metal cutting machine, a sheet metal bending machine, a sheet metal punching machine or some other sheet metal processing machine.
Blech verarbeitende Unternehmen bearbeiten üblicherweise verschiedenartige Aufträge ihrer Kunden. Die verschiedenartigen Aufträge erfordern regelmäßig das Verarbeiten von Blechen verschiedener Dicken und/oder unterschiedlicher werkstoffmäßiger Zusammensetzungen. Die einzelnen Aufträge sind mengenmäßig meist nie so umfangreich, dass das gesamte, in Form eines Coils aufgewickelte Blech mit einer bestimmten Dicke und/oder Zusammensetzung in einem Arbeitsgang von der Verarbeitungsmaschine verarbeitet wird. Vielmehr muss der Verarbeitungsmaschine auftragsabhängig mal die eine und mal die andere Art von Blech zur Verarbeitung zugeführt werden.Sheet metal processing companies usually process various types of orders from their customers. The various jobs regularly require the processing of sheets of different thicknesses and / or different material compositions. In terms of quantity, the individual orders are usually never so extensive that the entire sheet metal wound in the form of a coil with a certain thickness and / or composition is processed by the processing machine in one operation. Rather, depending on the job, the processing machine has to be fed one type of sheet metal for processing, and then the other.
Vor diesem Hintergrund ist es bekannt, für eine Verarbeitungsmaschine zum Verarbeiten von Blech ein sogenanntes Coillager zur Verfügung zu stellen, in welchem Coils aus unterschiedlichem Blech, beispielsweise Bleche mit unterschiedlichen Dicken, bereitgehalten werden.Against this background, it is known to provide a so-called coil store for a processing machine for processing sheet metal, in which coils made of different sheet metal, for example sheets of different thicknesses, are kept ready.
Ein bekanntes Coillager ist beispielsweise in der

Es ist daher die Aufgabe der vorliegenden Erfindung, ein Verfahren zum räumlichen Anordnen von Coils in einem Coillager sowie eine Kombination aus einer Verarbeitungsmaschine und einem Coillager zum Bereithalten mehrerer Coils für die Verarbeitung des Blechs der Coils mittels der Verarbeitungsmaschine zu schaffen, das bzw. die das Lagern von Coils mit möglichst vielen unterschiedlichen Blechdicken und/oder Blecharten auf möglichst geringem Raum ermöglicht.It is therefore the object of the present invention to provide a method for the spatial arrangement of coils in a coil store as well as a combination of a processing machine and a coil store for keeping several coils ready for processing the sheet metal of the coils by means of the processing machine, the or the Storage of coils with as many different sheet thicknesses and / or sheet types as possible in the smallest possible space.
Diese Aufgabe wird mit einem Verfahren mit den Merkmalen des Anspruchs 1 sowie mit einer Kombination aus einer Verarbeitungsmaschine und einem Coillager mit den Merkmalen des Anspruchs 3 gelöst. Weitere Merkmale der vorliegenden Erfindung ergeben sich aus den Unteransprüchen.This object is achieved with a method with the features of
Erfindungsgemäß wird ein Verfahren zum räumlichen Organisieren bzw. Anordnen von Coils in einem Coillager vorgeschlagen, in welchem mehrere Coils lagerbar sind, wobei das Verfahren folgende Schritte umfasst:
- a) Bereitstellen von elektronischen Daten über einen Anfangslagerzustand, welche Informationen über einen jeweiligen Anfangsdurchmesser aller Coils und über eine jeweilige räumliche Anfangslagerposition aller Coils in dem Coillager enthalten,
- b) Transportieren eines ausgewählten Coils mit einer bestimmten Blechdicke und/oder einer bestimmten Blechzusammensetzung von seiner Anfangslagerposition zu einer Verarbeitungsmaschine zum Verarbeiten eines Teils des bestimmten Blechs des ausgewählten Coils,
- c) Sensorisches Erfassen eines verringerten Durchmessers des ausgewählten Coils, nachdem der Teil des Blechs des ausgewählten Coils für das Verarbeiten durch die Verarbeitungsmaschine von dem ausgewählten Coil entfernt bzw. abgespult wurde, so dass die Menge des auf dem ausgewählten Coil verbleibenden Blechs um den von der Verarbeitungsmaschine zu verarbeitenden bzw. verarbeiteten Blechanteil verringert wurde,
- d) Elektronisches Speichern des verringerten Durchmessers des ausgewählten Coils,
- e) Transportieren des den verringerten Durchmesser aufweisenden, ausgewählten Coils zu einer Ablagelagerposition, die in Abhängigkeit von dem verringerten Durchmesser des ausgewählten Coils abweichend von seiner Anfangslagerposition in Lagerraum sparender Weise von einer elektronischen, programmierten Anlagensteuerung derart gewählt wird, dass der Abstand zwischen einer Coilachse des ausgewählten Coils und einer Coilachse eines dem ausgewählten Coil in dem Coillager benachbarten Coils in der Ablagelagerposition kleiner ist als in der Anfangslagerposition, und
- f) Elektronisches Speichern der Ablagelagerposition des ausgewählten Coils.
- a) Providing electronic data about an initial storage status, which contains information about a respective starting diameter of all coils and about a respective spatial starting storage position of all coils in the coil storage,
- b) transporting a selected coil with a specific sheet thickness and / or a specific sheet composition from its initial storage position to a processing machine for processing part of the specific sheet of the selected coil,
- c) Sensory detection of a reduced diameter of the selected coil after the part of the sheet metal of the selected coil has been removed or unwound from the selected coil for processing by the processing machine, so that the amount of sheet remaining on the selected coil by that of the Processing machine to be processed or processed sheet metal part has been reduced,
- d) Electronic storage of the reduced diameter of the selected coil,
- e) Transporting the selected coil having the reduced diameter to a storage storage position which, depending on the reduced diameter of the selected coil and deviating from its initial storage position in a storage space-saving manner, is selected by an electronic, programmed system control in such a way, that the distance between a coil axis of the selected coil and a coil axis of a coil adjacent to the selected coil in the coil store is smaller in the deposit storage position than in the initial storage position, and
- f) Electronic storage of the storage position of the selected coil.
Die voranstehende Reihenfolge der Schritte a) bis f) entspricht nicht zwingend der im Ablauf des erfindungsgemäßen Verfahrens einzuhaltenden chronologischen Schrittreihenfolge. Soweit es der technische Kontext des Verfahrens zulässt, kann ohne Weiteres eine andere chronologische Reihenfolge der Verfahrensschritte gewählt werden. Beispielsweise ist denkbar, die Speicherschritte d) und f) gleichzeitig nach dem Transportschritt e) durchzuführen. Da die Daten der Ablagelagerposition bereits vor dem tatsächlichen Transport des ausgewählten Coils zu der Ablagelagerposition gemäß Schritt e) aus der Verringerung des Durchmessers des ausgewählten Coils und seiner vorherigen Anfangslagerposition errechnet werden können, wäre es auch möglich, die Speicherschritte d) und f) ggf. vor dem tatsächlichen Transport gemäß Schritt e) vorzunehmen.The above sequence of steps a) to f) does not necessarily correspond to the chronological sequence of steps to be followed in the course of the method according to the invention. As far as the technical context of the process allows, another chronological order of the process steps can easily be selected. For example, it is conceivable to carry out storage steps d) and f) simultaneously after transport step e). Since the data of the storage location can already be calculated before the actual transport of the selected coil to the storage location in accordance with step e) from the reduction in the diameter of the selected coil and its previous initial storage position, it would also be possible to use storage steps d) and f) if necessary before the actual transport according to step e).
Während der Verarbeitung von Blechen verschiedener Art mit der Verarbeitungsmaschine wird genau dasjenige Coil mit dem jeweils zu verarbeitenden Blech (ausgewähltes Coil) an die Verarbeitungsmaschine herantransportiert. Ein Teil des Blechs wird dann von dem ausgewählten Coil abgewickelt bzw. abgespult und in der Verarbeitungsmaschine verarbeitet. Danach wird das ausgewählte Coil wieder in das Coillager zurück transportiert, wo es auf den nächsten Auftrag wartet, zu dessen Abarbeitung genau das Blech dieses ausgewählten Coils benötigt wird. Somit nehmen die Durchmesser, genauer die Außendurchmesser, aller im Coillager befindlichen Coils mit fortschreitender Blechverarbeitung früher oder später mehr oder weniger stark ab. Das erfindungsgemäße Verfahren nutzt in geschickter Weise den dadurch zwischen den einzelnen Coils zunehmend entstehenden Freiraum als Lagerplatz zur Coillagerung.During the processing of sheet metal of different types with the processing machine, precisely that coil with the sheet metal to be processed (selected coil) is transported to the processing machine. A part of the sheet metal is then unwound or unwound from the selected coil and processed in the processing machine. The selected coil is then transported back to the coil store, where it waits for the next order, which requires exactly the sheet metal of this selected coil for processing. Thus, the diameter, more precisely the outer diameter, of all coils in the coil store decrease sooner or later to a greater or lesser extent as sheet metal processing progresses. The inventive method uses in a skilful manner the thereby between The individual coils are increasingly free space as a storage space for coil storage.
Die Durchführung des erfindungsgemäßen Verfahrens erfolgt mit Hilfe einer elektronischen, programmierten Anlagensteuerung. In ihr sind die ggf. unterschiedlich großen Anfangsdurchmesser aller Coils sowie die räumlichen Lagekoordinaten der Anfangslagerpositionen aller Coils in dem Coillager gespeichert. Die Anfangslagerpositionen können beispielsweise in Form der jeweiligen räumlichen Koordinate der Coilachse jedes Coils gespeichert sein.The method according to the invention is carried out with the aid of an electronic, programmed system control. The initial diameters of all coils, which may differ in size, and the spatial coordinates of the initial storage positions of all coils in the coil store are stored in it. The initial storage positions can be stored, for example, in the form of the respective spatial coordinate of the coil axis of each coil.
Steht ein Auftrag zur Verarbeitung des Blechs des ausgewählten Coils an, so wird dieses zu der Verarbeitungsmaschine transportiert und ein Teil seines Blechs wird verarbeitet. Der verringerte Durchmesser des ausgewählten Coils wird mit Hilfe eines Sensors, vorzugsweise einem optischen Lasersensor, elektronisch von der Anlagensteuerung erfasst.If there is an order to process the sheet metal of the selected coil, it is transported to the processing machine and part of its sheet metal is processed. The reduced diameter of the selected coil is detected electronically by the system control with the aid of a sensor, preferably an optical laser sensor.
Nach dem Zurücktransport des ausgewählten Coils von der Verarbeitungsmaschine in das Coillager erfolgt die Ablage des Coils nicht wieder an seiner Anfangslagerposition, die es vor der Abholung für die Abarbeitung des Auftrags eingenommen hatte. Stattdessen berechnet die Anlagensteuerung eine von der Anfangslagerposition abweichende Ablagelagerposition, wobei in die Berechnung der Ablagelagerposition der verringerte Durchmesser des Coils einfließt. Aufgrund des verringerten Durchmessers des ausgewählten Coils kann seine Coilachse näher an der Coilachse eines benachbarten Coils angeordnet werden.After the selected coil has been transported back from the processing machine to the coil store, the coil is not returned to its initial storage position that it had assumed before being picked up for processing the order. Instead, the system control calculates a storage storage position that deviates from the initial storage position, with the reduced diameter of the coil being included in the calculation of the storage storage position. Due to the reduced diameter of the selected coil, its coil axis can be arranged closer to the coil axis of an adjacent coil.
Diese Annäherung des ausgewählten Coils mit verringertem Durchmesser an ein benachbartes Coil erfolgt beispielsweise derart, dass die Coilachse des ausgewählten Coils um die Hälfte der Verringerung seines Durchmessers von ihrer Anfangslagerposition in Richtung des benachbarten Coils versetzt abgesetzt wird. In diesem Fall ist dann der Abstand der zylinderförmigen Außenoberflächen des abgesetzten, ausgewählten Coils und des ihm benachbarten Coils so groß wie er war als das ausgewählte Coil noch seinen größeren Anfangsdurchmesser aufwies und noch an seiner Anfangslagerposition angeordnet war. Auf diese Weise rückt das ausgewählte und in das Coillager zurück transportierte Coil in der Reihe der im Coillager befindlichen Coils räumlich vorzugsweise in Richtung der Verarbeitungsmaschine auf.This approach of the selected coil with reduced diameter to an adjacent coil takes place, for example, in such a way that the coil axis of the selected coil is offset by half the reduction in its diameter from its initial storage position in the direction of the adjacent coil. In this case, the distance between the cylindrical outer surfaces of the offset, selected coil and the one adjacent to it is then Coils as big as they were when the selected coil still had its larger initial diameter and was still in its initial storage position. In this way, the coil selected and transported back into the coil store moves spatially preferably in the direction of the processing machine in the row of coils located in the coil store.
Nach dem Abarbeiten eines Blechverarbeitungsauftrages und dem Zurücktransport des ausgewählten Coils an die Ablagelagerposition in dem Coillager kann die elektronische Anlagensteuerung den verringerten Durchmesser des ausgewählten Coils und die räumlichen Koordinaten der Ablagelagerposition als neuen Anfangslagerzustand im Sinne des Verfahrensschritts a) speichern. Auf Grundlage dieses neuen Anfangslagerzustands kann dann der nächste Zyklus der Schritte b) bis f) des erfindungsgemäßen Verfahrens durchgeführt werden.After a sheet metal processing order has been processed and the selected coil has been transported back to the storage location in the coil storage, the electronic system control can save the reduced diameter of the selected coil and the spatial coordinates of the storage location as the new initial storage status in terms of method step a). On the basis of this new initial storage condition, the next cycle of steps b) to f) of the method according to the invention can then be carried out.
Mit jedem weiteren Blechverarbeitungsauftrag findet wiederholt ein Zyklus gemäß der Schritte b) bis f) statt, so dass sich in dem Coillager ein räumliches Aufrücken oder Zusammenrücken der gelagerten Coils ergibt. Sobald dadurch in dem in seinen räumlichen Außenabmessungen gleich groß bleibenden Coillager genügend Platz für ein zusätzliches Coil frei geworden ist, kann dieses zusätzlich in das Coillager aufgenommen werden. Das Coillager nimmt dann ein Coil mehr auf als es in dem ursprünglichen Anfangslagerzustand aufgenommen hatte. Das zusätzliche Coil kann insbesondere aus einem Blech sein, dessen Blechdicke und/oder Blechart in dem ursprünglichen Anfangslagerzustand noch nicht vorhanden war.With each further sheet metal processing order, a cycle according to steps b) to f) takes place repeatedly, so that the stored coils move closer or closer together in the coil store. As soon as sufficient space has become free for an additional coil in the coil store, which remains the same in terms of its external spatial dimensions, this can also be added to the coil store. The coil store then takes one more coil than it had taken in the original initial storage condition. The additional coil can, in particular, be made of a sheet metal whose sheet thickness and / or sheet type was not yet available in the original initial storage condition.
Das Transportieren gemäß der Schritte b) und e) erfolgt mittels einer Coiltransporteinrichtung, bei der es sich vorzugsweise um eine Coilhebeeinrichtung handelt. Diese hebt das ausgewählte Coil über die im Lager verbleibenden Coils an, transportiert sie translatorisch zu der Verarbeitungsmaschine und spult schließlich den von der Verarbeitungsmaschine zu verarbeitenden Teil des Blechs von dem ausgewählten Coil ab. Letzteres ist besonders vorteilhaft, da im Bereich der Verarbeitungsmaschine keine separate Abspulvorrichtung angeordnet werden muss, an welche das ausgewählte Coil übergeben werden müsste. Die auch die Funktion des Abspulens übernehmende Coiltransporteinrichtung vermeidet somit einen mechanischen Übergabeschritt des abzuspulenden Coils und somit ein damit verbundenes Risiko von Fehlfunktionen während eines Übergabevorgangs.The transport according to steps b) and e) takes place by means of a coil transport device, which is preferably a coil lifting device. This lifts the selected coil over the coils remaining in the store, transports them in translation to the processing machine and finally unwinds the part of the sheet metal to be processed by the processing machine from the selected coil. The latter is particularly advantageous since no separate unwinding device has to be arranged in the area of the processing machine to which the selected coil would have to be transferred. The coil transport device, which also takes on the function of unwinding, thus avoids a mechanical transfer step of the coil to be unwound and thus the associated risk of malfunctions during a transfer process.
Erfindungsgemäß wird des Weiteren eine Vorrichtung in Form einer Kombination aus einer Verarbeitungsmaschine und einem Coillager zum Bereithalten mehrerer Coils für die Verarbeitung des Blechs der Coils mittels der Verarbeitungsmaschine vorgeschlagen. Sie umfasst eine in dem Coillager angeordnete Aufnahmeeinrichtung zur lagernden Aufnahme aller Coils jeweils an einer beliebigen Stelle der Aufnahmeeinrichtung. Es ist eine elektronische Speichereinrichtung vorhanden, in welcher elektronische Daten über einen Anfangslagerzustand speicherbar sind, wobei diese Daten Informationen über einen jeweiligen Anfangsdurchmesser der Coils und eine jeweilige räumliche Anfangslagerposition der Coils in dem Coillager enthalten. Die räumliche Anfangslagerposition wird beispielsweise in Form der räumlichen Koordinaten der Coilachse eines jeden Coils gespeichert.According to the invention, a device in the form of a combination of a processing machine and a coil store for holding several coils ready for processing the sheet metal of the coils by means of the processing machine is also proposed. It comprises a receiving device arranged in the coil store for the storage of all coils at any point on the receiving device. There is an electronic storage device in which electronic data about an initial storage status can be stored, these data containing information about a respective initial diameter of the coils and a respective spatial initial storage position of the coils in the coil store. The initial spatial storage position is stored, for example, in the form of the spatial coordinates of the coil axis of each coil.
Eine Coiltransporteinrichtung transportiert ein ausgewähltes Coil von seiner Anfangslagerposition an einer ersten Stelle der Aufnahmeeinrichtung zu der Verarbeitungsmaschine zum Verarbeiten eines Teils des Blechs des ausgewählten Coils. Danach weist das ausgewählte Coil einen verringerten Durchmesser, genauer Außendurchmesser, auf. Die Coiltransporteinrichtung kann außerdem das den verringerten Durchmesser aufweisende, ausgewählte Coil zu einer eine Ablagelagerposition bildenden zweiten Stelle der Aufnahmeeinrichtung transportieren, die von der ersten Stelle der Aufnahmeeinrichtung abweicht und von der elektronischen Anlagensteuerung in Anhängigkeit von dem verringerten Durchmesser des ausgewählten Coils in Lagerraum sparender Weise derart gewählt ist, dass der Abstand zwischen einer Coilachse des ausgewählten Coils und einer Coilachse eines dem ausgewählten Coil in dem Coillager benachbarten Coils in der Ablagelagerposition kleiner ist als in der Anfangslagerposition.A coil transport device transports a selected coil from its initial storage position at a first location of the receiving device to the processing machine for processing part of the sheet metal of the selected coil. Thereafter, the selected coil has a reduced diameter, more precisely the outer diameter. The coil transport device can also transport the selected coil having the reduced diameter to a second location of the receiving device which forms a deposit storage position and which deviates from the first location of the receiving device and is controlled by the electronic system control depending on the reduced diameter of the selected coil in a way that saves storage space is chosen that the distance between a coil axis of the selected coil and a coil axis of the selected Coil in the coil storage adjacent coils in the storage storage position is smaller than in the initial storage position.
Des Weiteren ist eine Sensoreinrichtung zum Erfassen des verringerten Durchmessers des ausgewählten Coils vorhanden, wobei das Erfassen des verringerten Durchmessers erfolgt, nachdem der Teil des Blechs des ausgewählten Coils für das Verarbeiten durch die Verarbeitungsmaschine von dem ausgewählten Coil entfernt wurde. Bei der Sensoreinrichtung handelt es sich vorzugsweise um einen optischen Lasersensor, der in elektronischer Signalverbindung mit der Anlagensteuerung steht.Furthermore, a sensor device is provided for detecting the reduced diameter of the selected coil, the detection of the reduced diameter taking place after the part of the sheet metal of the selected coil has been removed from the selected coil for processing by the processing machine. The sensor device is preferably an optical laser sensor which is in electronic signal connection with the system control.
In vorteilhafter Weise weist die Coiltransporteinrichtung eine Abspuleinrichtung zum Abspulen des zu verarbeitenden Teils des Blechs des ausgewählten Coils in Richtung der Verarbeitungsmaschine auf.The coil transport device advantageously has an unwinding device for unwinding the part of the sheet metal of the selected coil to be processed in the direction of the processing machine.
Vorzugsweise umfasst die Aufnahmeeinrichtung zur lagernden Aufnahme aller Coils zwei längliche Lagerstützen, von denen jede eine horizontal verlaufende, längliche Oberkante aufweist. Die Lagerstützen sind derart voneinander beabstandet, dass alle Coils mit Hilfe an ihren Stirnseiten jeweils hervorstehender Achsstummel oder alternativ mit Hilfe zweier an der Coiltransporteinrichtung angebrachter Bolzen, die in Lagerschilde an den Haspeln der Coils eingreifen können, an beliebigen Stellen der beiden horizontalen Oberkanten zum Bereithalten für die Verarbeitungsmaschine ablegbar sind. Diese beliebigen Stellen entlang der Oberkanten bilden eine geometrisch kontinuierliche Vielzahl von Lagerpunkten, an denen die Coils abgelegt werden können. Eine Beschränkung der von der Coiltransporteinrichtung anfahrbaren Lagerpunkte durch diskret voneinander beabstandete Lagerböcke oder ähnliches ist nicht gegeben.The receiving device for the storage of all coils preferably comprises two elongated bearing supports, each of which has a horizontally extending, elongated upper edge. The bearing supports are spaced from one another in such a way that all coils can be held ready at any point on the two horizontal upper edges with the help of stub axles protruding from their end faces or, alternatively, with the help of two bolts attached to the coil transport device, which can engage in bearing shields on the reels of the coils the processing machine can be put down. These arbitrary points along the upper edges form a geometrically continuous multitude of storage points at which the coils can be deposited. There is no restriction of the bearing points that the coil transport device can approach by means of bearing blocks or the like that are discretely spaced from one another.
Die Sensoreinrichtung zum Erfassen des verringerten Durchmessers des ausgewählten Coils ist in vorteilhafter Weise an der Coiltransporteinrichtung angeordnet.The sensor device for detecting the reduced diameter of the selected coil is advantageously arranged on the coil transport device.
