Description

Die Erfindung betrifft eine Anlage zum Sortieren von von einer automatischen Bearbeitungsmaschine, z.B. einer Metallsäge, abge­führten Werkstücken, z.B. Sägeabschnitten.The invention relates to a system for sorting from an automatic processing machine, e.g. a hacksaw, removed workpieces, e.g. Saw sections.

Zum sortierten Abführen von Sägeabschnitten von einer Metallsäge ist es bekannt, an der Abfuhrseite der Bearbeitungsmaschine einen auf Schienen geführten Wagen vorzusehen, der in vorge­gebenen Abständen von der Bearbeitungsmaschine seinen Inhalt entleert. Nachteilig bei dieser Anlage ist, daß der Wagen für einen Abführvorgang eine Hin- und Herbewegung ausführen muß, also eine Leerfahrt hat.For the sorted removal of saw sections from a hacksaw, it is known to provide a carriage guided on rails on the discharge side of the processing machine, which trolley empties its contents at predetermined intervals. A disadvantage of this system is that the carriage has to perform a back and forth movement for a removal process, that is to say it has an empty run.

Der Erfindung liegt die Aufgabe zugrunde, eine Anlage zum Sortieren von Werkstücken zu schaffen, welche fortlaufend, d.h. ohne Unterbrechung, die von einer Bearbeitungsmaschine abge­gebenen Werkstücke abführt und sortiert.The invention has for its object to provide a system for sorting workpieces that continuously, i. Without interruption, the workpieces delivered by a processing machine are removed and sorted.

Gelöst wird diese Aufgabe durch die Merkmale des Anspruchs 1. Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by the features of claim 1. Further developments of the invention are specified in the subclaims.

Die Erfindung wird beispielhaft anhand der Zeichnung beschrieben, in der sind

  • Fig. 1 eine Seitenansicht der Sortieranlage,
  • Fig. 2 eine Vorderansicht der Anlage,
  • Fig. 3 eine Draufsicht der Anlage,
  • Fig. 4 eine Vorderansicht der Abteile von Aufnahmebehältern in größerem Maßstab und
  • Fig. 5 eine Seitenansicht eines Abteils eines Aufnahmebe­hälters.
The invention is described by way of example with reference to the drawing, in which:
  • 1 is a side view of the sorting system,
  • 2 is a front view of the system,
  • 3 is a plan view of the plant,
  • Fig. 4 is a front view of the compartments of receptacles on a larger scale and
  • Fig. 5 is a side view of a compartment of a receptacle.

Gemäß Fig. 1 ist an der Abfuhrseite der (nicht dargestellten) Sägemaschine ein Auflagetisch 1 angebracht, und zwar unmittelbar anliegend an das Sägeblatt 2. An dem Auflagetisch ist ein Greifer 3 angebracht, der den Sägeabschnitt 4 auf das Transport­band 5 legt. Das Transportband 5 weist einen Antrieb 6 auf. Das Transportband 5 ist ein mit einem Mittelscharnier versehenes Gliederband, dessen beide Seiten mittels auf Führungen wirkenden Kippzylindern 7 und 8 abgekippt werden können, womit die Sägeabschnitte längs der Pfeile 7' und 8' von dem Transportband nach den Seiten abgeworfen werden. Der Antrieb 6 des Transportbands 5 steht über einen Riemen oder eine Kette in Verbindung mit einem Meßwertgeber 9 für die Transportstrecke.According to FIG. 1, a support table 1 is attached to the discharge side of the sawing machine (not shown), namely directly adjacent to the saw blade 2. A gripper 3 is attached to the support table, which places the sawing section 4 on the conveyor belt 5. The conveyor belt 5 has a drive 6. The conveyor belt 5 is a link hinge provided with a central hinge, the two sides of which can be tilted by means of tilting cylinders 7 and 8 acting on guides, whereby the saw sections along the arrows 7 'and 8' are thrown off the conveyor belt to the sides. The drive 6 of the conveyor belt 5 is connected via a belt or a chain to a transmitter 9 for the transport route.

Beidseitig des Transportbands 5 sind Aufnahmebehälter 10 bis 17 aufgestellt, die beliebige Abmessungen aufweisen können, ins­besondere von Kunden gelieferte Aufnahmebehälter sein können. Ein weiterer Aufnahmebehälter 18 ist unter dem Ende des Trans­portbands 5 vorgesehen. In den Behältern liegen die sortierten Sägeabschnitte 19. Die Aufnahmebehälter 10 bis 17 sind in Abteilen angeordnet, die durch Trennwände 20 bis 29 gebildet sind, die in Transportrichtung des Bandes verschiebbar sind, um die Abteile den Abmessungen der jeweils gewünschten Aufnahme­behälter anzupassen. An den Trennwänden sind Bügel 30 bis 33 (Fig. 4) angebracht, in welche die Aufnahmebehälter eingehängt werden. An den oberen Enden der Trennwände sind Leitbleche 34 bis 37 angebracht, um die von dem Transportband abgeworfenen Sägeabschnitte sicher in die Aufnahmebehälter zu führen. Des weiteren können an den oberen Enden der Trennwände Ablage­schienen 38 mit Kunststoffauflagen 39 angebracht sein, um auch längere Stangen, deren Länge die Breite der verfügbaren Auf­nahmebehälter übersteigt, sortiert ablegen zu können.On both sides of the conveyor belt 5, receptacles 10 to 17 are set up, which can have any dimensions, in particular can be receptacles supplied by customers. Another receptacle 18 is provided under the end of the conveyor belt 5. The sorted sawing sections 19 lie in the containers. The receiving containers 10 to 17 are arranged in compartments which are formed by dividing walls 20 to 29 which can be displaced in the direction of transport of the strip in order to adapt the compartments to the dimensions of the respectively desired receiving containers. Brackets 30 to 33 (FIG. 4), in which the receptacles are suspended, are attached to the partition walls. Baffles 34 to 37 are attached to the upper ends of the dividing walls in order to safely guide the saw sections thrown off the conveyor belt into the receptacles. Furthermore, storage rails 38 with plastic supports 39 can be attached to the upper ends of the dividing walls in order to be able to store even longer rods, the length of which exceeds the width of the available receptacle, in a sorted manner.

Eine Steuervorrichtung 40 ist über eine Leitung 41 mit dem Meß­wertgeber 9 und über Leitungen 42 und 43 mit den Kippzylindern 7 und 8 verbunden. Die Steuervorrichtung wird mit Daten 44 der Zahl, Abmessungen und Bestimmung der Werkstücke 4 bzw. 19 und der Lage und Abmessungen der Aufnahmebehälter 10 bis 17 einer zu bearbeitenden Partie von Werkstücken gespeist und verarbeitet die Daten zu zeitlich abgestimmten Steuerbefehlen für jeweils einen der Kippzylinder 7, 8 unter Berücksichtigung der von dem Meßwertgeber 9 jeweils zu ermittelnden Strecke des Transports der Werkstücke auf dem Transportband 5.A control device 40 is connected via a line 41 to the transmitter 9 and via lines 42 and 43 to the tilt cylinders 7 and 8. The controller is provided with data 44 The number, dimensions and determination of the workpieces 4 and 19 and the position and dimensions of the receptacles 10 to 17 of a batch of workpieces to be machined are fed and processed by the data to timed control commands for each of the tilt cylinders 7, 8, taking into account those from the transmitter 9 route of the transport of the workpieces to be determined on the conveyor belt 5.

Die Arbeitsweise der erfindungsgemäßen Anlage ist wie folgt.The operation of the system according to the invention is as follows.

Die Sägemaschine ist mit einer Steuerung versehen, welche die zu sägenden Partien nach Auftraggeber, Termin, Zahl, Werkstückgröße etc. registriert. Darüber hinaus werden die Abmessungen der für die gesägten Partien vorgesehenen Aufnahmebehälter und ihre Standorte längs des Transportbands gespeichert. Beim Sägen einer bestimmten Partie werden aus den in der Steuerung verarbeiteten Daten Signale an den Meßwertgeber 9 gegeben, der daraufhin die für das Transportband mit den Werkstücken dieser Partie zurück­zulegende Strecke festlegt. Wenn ein von der Bearbeitungs­maschine abgeführter Sägeabschnitt diese Strecke durchlaufen hat, wird er von dem Transportband abgeworfen, sei es durch Kippen des Transportbands nach einer bestimmten Seite oder auf andere Weise, beispielsweise mittels eines Schiebers abge­schoben. Dabei wird die von dem Sägeabschnitt auf dem Transport­band zurückzulegende Strecke unter Berücksichtigung der Band­laufgeschwindigkeit so festgelegt, daß der Sägeabschnitt an der Abwurfstelle in definierter Lage zum Aufnahmebehälter, z.B mit seiner Mitte auf die Mitte des Aufnahmebehälters positioniert ist.The sawing machine is equipped with a control system that registers the parts to be sawn according to the client, date, number, workpiece size, etc. In addition, the dimensions of the receptacles intended for the sawn lots and their locations along the conveyor belt are stored. When sawing a certain lot, signals are sent from the data processed in the control to the measuring value transmitter 9, which then determines the distance to be covered for the conveyor belt with the workpieces of this lot. When a saw section carried away by the processing machine has passed this distance, it is thrown off the conveyor belt, whether by tipping the conveyor belt to a certain side or in another way, for example by means of a slide. The distance to be covered by the saw section on the conveyor belt is determined taking into account the belt running speed so that the saw section is positioned at the discharge point in a defined position relative to the receiving container, for example with its center on the center of the receiving container.

Die Sägeabschnitte müssen auf dem Transportband so festliegen, daß sie sich nicht in dessen Längsrichtung verschieben können, weil andernfalls die registrierte zurückzulegende Transportstrecke nicht mit der tatsächlichen Transportstrecke übereinstimmt. Die muldenförmige Ausbildung des Transportbands unterstützt das Halten des Sägeabschnitts an der gewünschten Stelle des Transportbands.The saw sections must be fixed on the conveyor belt so that they cannot move in the longitudinal direction, because otherwise the registered transport route to be covered does not match the actual transport route. The trough-shaped design of the conveyor belt supports holding the saw section at the desired location on the conveyor belt.

Da die Steuerung auch die Abmessungen des Sägeabschnitts und der Aufnahmebehälter überwacht, wird sichergestellt, daß nicht zu lange Sägeabschnitt in zu schmale Aufnahmebehälter abgeworfen werden.Since the controller also monitors the dimensions of the saw section and the receptacle, it is ensured that the saw section that is not too long is thrown into receptacles that are too narrow.

Die erfindungsgemäße Anlage ermöglicht es, daß laufend die von der Sägemaschine geschnittenen Abschnitte abgeführt und sortiert abgeworfen werden, so daß kein Stau der Sägeabschnitte auftritt. Allerdings kann es auch erwünscht sein, mehrere gleiche Säge­abschnitte an einer bestimmten Stelle des Transportes ansammeln zu lassen und gemeinsam in enen Aufnahmebehälter abzuwerfen. Rest- und Schrottstücke können in dem am Ende des Transportbands angeordneten Aufnahmebehälter 18 abgeworfen werden.The system according to the invention makes it possible for the sections cut by the sawing machine to be continuously removed and sorted so that there is no jam in the sawing sections. However, it may also be desirable to have several identical saw sections accumulate at a certain point in the transport and to drop them together into a receptacle. Remnants and scrap pieces can be dropped in the receptacle 18 arranged at the end of the conveyor belt.

Durch die Aufhängung der Aufnahmebehälter an den Trennwänden bleibt unter den Aufnahmebehältern ein freier Raum, so daß diese nach Beendigung des Sortiervorgangs mit einem Hubwagen abtrans­portiert werden können.Due to the suspension of the receptacles on the partition walls, a free space remains under the receptacles, so that they can be transported away with a pallet truck after the sorting process has ended.

Die Steuerung der Sägemaschinen kann so ausgelegt werden, daß unter Berücksichtigung der Zahl und Abmessungen der Säge­abschnitte und der Abmessungen der Aufnahmebehälter eine optimale Zuordnung erfolgt, wobei im Einzelfall auch eine Mehr­fachbelegung von Aufnahmebehältern vorgesehen werden kann. Des weiteren kann die Steuerung auch die Transportstrecken unter Berücksichtigung von Abmessungen und Gewicht der Sägeabschnitte optimieren.The control of the sawing machines can be designed in such a way that, taking into account the number and dimensions of the sawing sections and the dimensions of the receptacles, an optimal allocation takes place, whereby in individual cases a multiple assignment of receptacles can also be provided. Furthermore, the control can also optimize the transport routes taking into account the dimensions and weight of the saw sections.
