Further conveying paths (TS') are provided for subsequently feeding the items of post to a combining arrangement (4) and the channelling device (2). The items of post are permanently grasped as they are conveyed on the conveying paths (TS, TS') and the weighing systems (WS1, ..., WSn).

Description

Vorrichtung zur automatischen Gewichtsbestimmung von Poststucken Device for automatically determining the weight of postal items
Beschreibungdescription
Die vorliegende Erfindung betrifft eine Vorrichtung zur automatischen Gewichtsbestimmung von Poststucken gemäß dem Oberbegriff des Patentanspruchs 1The present invention relates to a device for automatically determining the weight of postal items according to the preamble of patent claim 1
In automatischen Briefverteilanlagen muß von flachen, flexiblen und leicht zerreißbaren Gegenstanden mit unterschiedlicher Lange, z B C6-Briefen, DL- Briefen, C5-Briefen, Postkarten, die als kontinuierlicher Strom transportiert werden, zu verschiedenen Zwecken das Gewicht bestimmt werden, ohne daß die Gegenstande gestoppt oder verzögert werden Schwierigkeiten können dadurch auftreten, daß grundsatzlich die Gewichtsbestimmung der Poststucke auch dann genau und sicher erfolgen soll, wenn die Poststucke mit hohen Geschwindigkeiten transportiert werden, z B oberhalb einer Geschwindigkeit von 2m/s Auch bei diesen Geschwindigkeiten dürfen die Poststucke nicht beschädigt werden Darüber hinaus ist es erforderlich, daß die Poststucke im kontinuierlichen Strom ihre relative Lage zueinander weitgehend erhalten Insbesondere sollen die Lucken zwischen den Poststucken durch die Gewichtsbestimmung nicht verändert werdenIn automatic mail distribution systems, the weight of flat, flexible and easily tearable objects of different lengths, for example C6 letters, DL letters, C5 letters, postcards, which are transported as a continuous stream, must be determined for various purposes without the weight Objects are stopped or delayed Difficulties can arise from the fact that the weight of the postal items should always be determined precisely and safely even when the postal items are transported at high speeds, for example above a speed of 2 m / s. Even at these speeds, the postal items are not allowed Be damaged In addition, it is necessary that the postal items largely maintain their relative position to one another in a continuous stream. In particular, the gaps between the postal items should not be changed by the weight determination
Bereits bekannt sind Verfahren, bei denen die zu wiegenden Gegenstande waagerecht über em Wagesystem geleitet und dabei dynamisch gewogen werden Allerdings treten dann bei höheren Geschwindigkeiten Verschiebungen zwischen den Gegenstanden auf, weil die Gegenstande vom Transportsystem nicht fest gefaßt werden, darüber hinaus gestatten diese Anordnungen keine hohen Durchsatze, da bei geringen Abstanden zwischen den Gegenstanden die einzelnen Gegenstande nicht lange genug im Wagesystem verbleiben, um das Gewicht mit ausreichender Genauigkeit zu bestimmen Wenn zwischen Gegenstanden unterschiedlicher Langen nur geringe Lücken bestehen, hat dies darüber hinaus die Konsequenz, daß kurze Gegenstande nicht allein im Wagesystem sind, so daß eine Gewichtsbestimmung in diesen Fallen gar nicht möglich ist Um dieses Problem zu losen, wurde der Strom der Gegenstande in mehrere Teilstrome gesplittet und die einzelnen Gegenstande mehreren Wagesystemen zugeführt. Dies ermöglicht grundsätzlich einen höheren Gesamtdurchsatz Allerdings besteht auch dann das Problem der Verschiebbarkeit der einzelnen liegenden Gegenstande der Teilstrome, so daß solche Anordnungen für höhere Geschwindigkeiten nicht anwendbar sind. Darüber hinaus besteht die Gefahr, daß die zu wiegenden Gegenstände beim Übergang zu dem Wägesystem beschädigt werden, insbesondere dann, wenn sie nicht starr und stabil genug sindMethods are already known in which the objects to be weighed are passed horizontally over a weighing system and are dynamically weighed.However, there are shifts between the objects at higher speeds because the objects are not firmly grasped by the transport system, and furthermore, these arrangements do not permit high arrangements Throughput, because with small distances between the objects, the individual objects do not remain in the weighing system long enough to determine the weight with sufficient accuracy.If there are only small gaps between objects of different lengths, this also has the consequence that short objects are not alone in the Weighing system, so that a weight determination in these cases are not possible at all. In order to solve this problem, the flow of the objects was split into several partial flows and the individual objects were fed to several weighing systems. This basically enables a higher total throughput. However, there is also the problem of the displaceability of the individual lying objects of the partial streams, so that such arrangements cannot be used for higher speeds. In addition, there is a risk that the objects to be weighed will be damaged during the transition to the weighing system, especially if they are not rigid and stable enough
Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung zur automatischen Gewichtsbestimmung von Poststücken zu schaffen, mit der eine Messung im kontinuierliche Strom erfolgen kann, wobei auch bei höheren Geschwindigkeiten Verschiebungen der relativen Position der Poststucke zueinander im Sendungsstrom vermieden werden. Diese Aufgabe wird erfindungsgemaß durch die Merkmale des Patentanspruchs 1 gelost.It is therefore an object of the present invention to provide a device for automatically determining the weight of mail pieces, with which a measurement can be carried out in a continuous stream, shifts in the relative position of the mail pieces to one another in the mail stream being avoided even at higher speeds. This object is achieved by the features of claim 1.
Die erfindungsgemäße Vorrichtung ermöglicht einen höheren Gesamtdurchsatz an Poststücken bei höherer Wiegegenauigkeit und Betriebssicherheit.The device according to the invention enables a higher total throughput of mail pieces with higher weighing accuracy and operational reliability.
Vorteilhafte Ausführungsformen der Erfindung sind in Unteranspruchen, sowie der Beschreibungen zu entnehmen.Advantageous embodiments of the invention can be found in the subclaims and in the descriptions.
Im folgenden wird die Erfindung anhand von Zeichnungen genauer beschrieben Dabei zeigen: Fig 1 ein Blockschaltbild einer erfindungsgemaßen VorrichtungThe invention is described in more detail below with reference to drawings, in which: FIG. 1 shows a block diagram of a device according to the invention

Wägesystem Fig. 3 das Layout für eine erfindungsgemäße Vorrichtung mit zwei WägesystemenWeighing system Fig. 3 shows the layout for a device according to the invention with two weighing systems
Fig. 1 zeigt das Blockschaltbild einer erfindungsgemäßen Vorrichtung. Die Poststücke werden einem Transportpfad TS mit einer Zufuhrvorrichtung 1 zugeführt, wobei die Poststücke während des Transports permanent gefaßt werden Dies hat zur Folge, daß jedes einzelne im Transportpfad TS in seiner Position vorangehenden und zum nachfolgenden Poststück fixiert ist. Die Zuführeinrichtung 1 ist über den Transportpfad TS vorzugsweise an eine Verteileinrichtung 3 angeschlossen. Die Poststücke werden in dieser Verteileinrichtung 3 auf eine Anzahl von Transportpfaden TS verteilt und den Wägesystemen WSi, WS2 WSN zugeführt Auch in diesen Transportpfaden TS werden die Poststucke permanent gefaßt und transportiert Innerhalb der Wagesysteme WSi, WS2. WSN werden die Poststucke ebenfalls permanent gefaßt und transportiert und anschließend Transportpfaden TS' übergeben und über diese Transportpfade TS' einer Vereinigungsvorrichtung 4 zugeführt Anschließend erfolgt eine Zuführung der Poststucke zu einer Ausschleusungsvorrichtung 2. Da die Poststücke in den Transportpfaden und den Wägesystemen permanent gefaßt und transportiert werden, ist der relative Abstand der Poststücke zueinander im Sendungsstrom bei der Zuführung zur erfindungsgemäßen Vorrichtung der gleiche wie bei der Ausschleusung1 shows the block diagram of a device according to the invention. The mail pieces are fed to a transport path TS with a feed device 1, the mail pieces being permanently grasped during the transport. This has the consequence that each individual piece of the mail item preceding and following in the transport path TS is fixed. The feed device 1 is preferably via the transport path TS to a distribution device 3 connected. The mail pieces are distributed in this distribution device 3 over a number of transport paths TS and fed to the weighing systems WSi, WS 2 WS N. The mail pieces are also permanently gripped and transported in these transport paths TS Within the weighing systems WSi, WS 2 . WSN, the mailpieces are also permanently gripped and transported, and then transport paths TS 'are handed over and fed via these transport paths TS ' to a combining device 4. The mailpieces are then fed to a rejecting device 2. Since the mailpieces are permanently gripped and transported in the transport paths and the weighing systems , the relative distance of the mail items to one another in the mail flow when they are fed to the device according to the invention is the same as when they are discharged
Fig. 2 zeigt, daß erfindungsgemaß die Transportpfade und die Wägesysteme Deckbandsysteme aufweisen zwischen denen die Poststücke festgeklemmt und transportiert werden. Ein solches Deckbandsystem besteht aus zwei parellel laufenden Riemen, die über Transportrollen und Antriebsrollen 5 - 12 geführt werden Poststucke werden in allen Transportsystemen TS, TS' Wägesystemen WSi, . WSN mit einer gleichen vorgegebenen Geschwindigkeit transportiert, so daß keine zusatzlichen Beschleunigungs- bzw. Bremskräfte an den Übergangsstellen zwischen Transportpfaden und Wägesystemen auftreten.2 shows that, according to the invention, the transport paths and the weighing systems have cover belt systems between which the mail items are clamped and transported. Such a cover belt system consists of two parallel belts which are guided over transport rollers and drive rollers 5 - 12. Post pieces are used in all transport systems TS, TS ' weighing systems WSi,. WSN is transported at the same predetermined speed so that no additional acceleration or braking forces occur at the transition points between transport paths and weighing systems.
Vorzugsweise weist jeder Transportpfad eine Antriebseinheit DU auf, die starr mit einem zentralen Antrieb D z.B. einem Motor verbunden ist, so daß in allen Transportpfaden und zwar sowohl hinter als auch vor den Wägesystemen die Poststucke mit exakt der gleichen Geschwindigkeit transportiert werden, wobei diese Geschwindigkeit selbst allerdings variabel ist. Das Ein- und Ausschalten des Antriebs D sowie eine mögliche Geschwindigkeitssteuerung erfolgt durch eine Steuereinheit CU.Each transport path preferably has a drive unit DU which is rigidly connected to a central drive D e.g. is connected to a motor, so that the mail pieces are transported at exactly the same speed in all transport paths, both behind and in front of the weighing systems, although this speed itself is variable. The drive D is switched on and off and a possible speed control is carried out by a control unit CU.
Wie bereits erwähnt, werden die Poststucke in den Wägesystemen möglichst mit genau der gleichen Geschwindigkeit transportiert wie in den Transportpfaden durch die die Zufuhr der Poststücke erfolgt bzw denen die Poststücke zugeführt werden, um eine Beschädigung der Poststücke zu vermeiden. Allerdings muß dabei eine mechanische Kopplung zwischen den Transportpfaden und den Wiegesystemen vermieden werden, da andernfalls keine genaue Gewichtsbestimmung durch die Wagesysteme möglich wäre. Erfindungsgemaß weist daher jedes Wagesystem eine Steuereinheit CUi, CU2, CUN auf, der von einem Geschwindigkeitssensor SS ein Signal als Maß für die Geschwindigkeit der Transportpfade TS bzw TS' zugeführt wird Jedes System weist weiterhin jeweils einen Sensor SS i, SS2 SSN auf, mit dem die lokale Transportgeschwindigkeit im Wagesystem bestimmt wird. Das Signal dieser lokalen Geschwindigkeitssensoren SSi, SS2 SSN wird jeweils den lokalen Steuereinheiten CUi, CU2. CUN zugeführt Jedes Wagesystem weist außerdem einen lokalen Antrieb Dj, D2 .DN auf, der von der Steuereinheit CUi, CU2 CUN auf die Geschwindigkeit der Transportpfade TS, TS' geregelt wird. Dies ermöglicht, eine Übergabe der Poststucke von den Transportpfaden TS in die Wagesystemen bzw von den Wägesystemen in die Transportpfade TS' vorzunehmen, ohne daß Geschwindigkeitsdifferenzen auftreten und zwar auch dann, wenn die Vorrichtung zu einem beliebigen Zeitpunkt wahrend des Betriebs abgeschaltet werden mußAs already mentioned, the mail pieces are transported in the weighing systems as precisely as possible at the same speed as in the transport paths through which the mail pieces are fed or to which the mail pieces are fed in order to avoid damage to the mail pieces. However, there must be a mechanical coupling between the transport paths and the weighing systems be avoided, since otherwise exact weight determination by the weighing systems would not be possible. According to the invention, each weighing system therefore has a control unit CUi, CU 2 , CU N , to which a signal from a speed sensor SS is supplied as a measure of the speed of the transport paths TS or TS ' . Each system also has a sensor SS i, SS 2 SS N with which the local transport speed in the weighing system is determined. The signal from these local speed sensors SSi, SS 2 SS N is sent to the local control units CUi, CU 2 . CU N supplied Each weighing system also has a local drive Dj, D 2 .D N , which is controlled by the control unit CUi, CU 2 CU N on the speed of the transport paths TS, TS ' . This enables the mail pieces to be transferred from the transport paths TS to the weighing systems or from the weighing systems to the transport paths TS ' without speed differences occurring, even if the device has to be switched off at any time during operation
Die Arbeitsweise der erfindungsgemaßen Vorrichtung ist folgendermaßen Poststucke werden über die Zuführvorrichtung 1 der erfindungsgemaßen Vorrichtung zugeführt, passieren zuerst einen Eingangssensor IS, z.B. eine Lichtschranke, der jedes Poststuck registriert und an die Steuereinheit CU weitermeldet Der Geschwindigkeitssensor SS bestimmt dieThe method of operation of the device according to the invention is as follows. Post pieces are fed via the feed device 1 of the device according to the invention, first pass through an input sensor IS, e.g. a light barrier that registers each piece of mail and forwards it to the control unit CU. The speed sensor SS determines the
Eingangsgeschwindigkeit der Poststucke im Transportpfad TS Dies ermöglicht auch, daß die Steuereinheit CU jedes Poststuck bei seinem Durchlauf durch die Vornchtung verfolgt, da der Aufenthaltsort jedes Poststücks durch Integration über die Zeit bestimmt werden kann. Die Poststucke werden als kontinuierlicher Strom der Verteileinrichtung 3 zugeführt und auf die Wagesysteme WSi bis WSN verteilt Die einzelnen Wägesysteme sind mechanisch von der übrigen Vorrichtung entkoppelt, so daß ihre Funktion nicht beeinträchtigt ist. Beim Passieren der Wagesysteme werden die Poststücke den Transportpfaden TS' zugeführt und in der Vereinigungseinrichtung 4 wieder zu einem kontinuierlichen Strom zusammengeführt, der über die Ausschleusungsvorrichtung 2 die Vorrichtung verläßtEntry speed of the mail pieces in the transport path TS This also enables the control unit CU to track each mail piece as it passes through the device, since the location of each mail piece can be determined over time by integration. The mail pieces are fed as a continuous stream to the distribution device 3 and distributed to the weighing systems WSi to WS N. The individual weighing systems are mechanically decoupled from the rest of the device, so that their function is not impaired. When passing through the weighing systems, the mail pieces are fed to the transport paths TS ' and brought together again in the combining device 4 to form a continuous stream which leaves the device via the discharge device 2
Fig 3 zeigt eine bevorzugte Ausführungsform der Vorrichtung mit zwei Wagesystemen Jedes Wagesystem WSi bzw WS2 befindet sich auf einer mechanisch von übrigen Vorrichtung entkoppelten Grundplatte 13 bzw. 14 Jedes Wagesystem weist ein Deckbandsystem 15 bzw. 16 auf, von dem die Poststucke wahrend der Gewichtsbestimmung transportiert werden. Die Zufuhrvorrichtung 1 weist ebenfalls Deckbandsysteme auf Als Verteil einrichtung 3 wird eine Weiche eingesetzt auf die die Poststucke jeweils über einen ersten bzw zweiten Transportpfad 17 bzw 18 geleitet werden. Diese Transportpfade sind ebenfalls durch Deckbandsysteme realisiert Nach Transport innerhalb der Wagesysteme erfolgt eine Übergabe der Poststucke an Transportpfade 19, 20, die die Poststucke zu der Vereinigungseinrichtung 4 transportieren. Auch diese Transportpfade sowie die Vereinigungseinrichtung sind ais Deckbandsysteme realisiert. Die Ubergabestellen zwischen den Transportpfaden und den Wägesystemen sind vorzugsweise durch versetzt angeordnete Transportrollen realisiert, so daß einerseits eine sichere Übergabe der Poststücke ermöglicht wird, andererseits das Wägesystem von der übrigen Vorrichtung mechanisch entkoppelt ist.3 shows a preferred embodiment of the device with two weighing systems. Each weighing system WSi or WS 2 is located on a base plate 13 or 14, each mechanically decoupled from the other device The weighing system has a shroud system 15 or 16, from which the items are transported during the weight determination. The feed device 1 also has cover belt systems. A switch is used as the distribution device 3, onto which the mail items are each guided via a first or second transport path 17 or 18. These transport paths are also realized by cover belt systems. After transport within the weighing systems, the mail pieces are transferred to transport paths 19, 20, which transport the mail pieces to the combining device 4. These transport paths as well as the combining device are also implemented as shroud systems. The transfer points between the transport paths and the weighing systems are preferably realized by staggered transport rollers, so that on the one hand a secure transfer of the mail items is made possible, and on the other hand the weighing system is mechanically decoupled from the rest of the device.
Die Wägesysteme selbst weisen zunächst die weiter oben angegebenen Merkmale auf, d.h. jeweils einen Antrieb, eine Steuereinrichtung einen Geschwindigkeitssensor sowie eine Transportstrecke in der die Poststücke permanent gefaßt transportiert werden Darüber hinaus wird für die Durchführung des eigentlichen Wiegevorgangs in den Wägesystemen eines der verschiedenen bekannten Wägeprinzipien verwendet. The weighing systems themselves initially have the features specified above, i.e. One drive each, one control device, one speed sensor and one transport route in which the mail items are permanently transported. In addition, one of the various known weighing principles is used to carry out the actual weighing process in the weighing systems.
