Description

Die Erfindung betrifft eine Belade- und Entladevorrichtung für an ihrem Falzrücken hängende Falzprodukte.The invention relates to a loading and unloading device for folding products hanging on their fold back.

Aus der US-A-4 478 398 ist es bereits bekannt, mittels einer umlaufenden Einrichtung, z. B. einer Kette, an der Stäbe angeordnet sind, Falzprodukte zu übernehmen, indem bei einer Aufwärtsbewegung der Stäbe jeweils unter den Falzrücken eines Falzproduktes eingeführt werden. An einer Abgabestation können die Falzprodukte auf eine weitere Transportvorrichtung übergeben werden. Mit dieser Vorrichtung ist eine Abspeicherung von Falzprodukten nicht möglich. Auch können die Falzprodukte mit dieser Vorrichtung nicht direkt aus einem Speicher entnommen werden.From US-A-4 478 398 it is already known to use a rotating device, e.g. B. a chain on which bars are arranged to take folded products by being inserted under the fold back of a folded product when the bars move upwards. The folded products can be transferred to another transport device at a delivery station. It is not possible to store folded products with this device. The folding products cannot be removed directly from a store with this device.

Aufgabe der Erfindung ist es, eine Vorrichtung aufzuzeigen, mit der an ihrem Falzrücken hängende Falzprodukte von der vorgenannten Einrichtung abgenommen oder von einem Speicher in Form einer Aufnahmevorrichtung an diese übertragen werden können. Diese Aufgabe wird durch die Anwendung der Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst. Aus der US-A-2 526 253 sind zwar bereits Transportvorrichtungen bekannt, bei denen im Abstand voneinander Elektromagnete befestigt sind, jedoch können mit dieser keine Falzprodukte in der vorangehend.beschriebenen Weise übernommen bzw. transportiert werden. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und aus der Beschreibung in Verbindung mit den Zeichnungen. In diesen zeigt jeweils schematisch:

  • Fig. 1 eine Vorrichtung zur Entnahme von Falzprodukten von einer Transportvorrichtung und zur Speicherung derselben in einer Aufnahmevorrichtung bzw. zur Beladung einer Transportvorrichtung von einer gefüllten Aufnahmevorrichtung.
  • Fig. 2 magnetisierbare Falzprodukt-Transportelemente und
  • Fig. 3 eine Vorrichtung zum Übergeben von in einem Speicher in Form einer transportierbaren Vorrichtung auf magnetisierbaren Transportelementen hängenden Falzprodukten auf an einer weiteren Transportvorrichtung befestigten Stäben.
The object of the invention is to provide a device by means of which folding products hanging on their fold back can be removed from the aforementioned device or transferred from a memory in the form of a holding device to the latter. This object is achieved by applying the features of the characterizing part of claim 1. From US-A-2 526 253, transport devices are already known in which electromagnets are fastened at a distance from one another, but no folded products can be taken over or transported with them in the manner described above. Further developments of the invention result from the subclaims and from the description in conjunction with the drawings. Each of these shows schematically:
  • Fig. 1 shows a device for removing folded products from a transport device and for storing them in a receiving device or for loading a transport device from a filled receiving device.
  • Fig. 2 magnetizable folded product transport elements and
  • 3 shows a device for transferring folded products hanging in a storage device in the form of a transportable device on magnetizable transport elements onto bars attached to a further transport device.

Die mit der erfindungsgemäßen Vorrichtung zu übernehmenden Falzprodukte 1 hängen an ihrem Falzrücken auf beidseitig einer Transportvorrichtung 3 angeordneten Transportelementen, vorzugsweise in Form von Stäben 2, die durch die Transportvorrichtung 3 entlang eines vorgegebenen Weges bewegbar sind. Letztere kann beispielsweise ein umlaufendes Hand- oder Kettensystem umfassen.The folded products 1 to be taken over with the device according to the invention hang on their fold back on transport elements arranged on both sides of a transport device 3, preferably in the form of bars 2, which can be moved along a predetermined path by the transport device 3. The latter can include, for example, a rotating hand or chain system.

Neben der Transportvorrichtung 3 gemäß Fig. 1 ist die erfindungsgemäße Vorrichtung 4 zur Übernahme und Speicherung der durch die Transportvorrichtung 3 angelieferten Falzprodukte 1 gezeigt. Diese umfaßt zumindest eine Aufnahmevorrichtung 5, in der die von der Transportvorrichtung 3 übernommenen Falzprodukte 1 gespeichert werden. Es ist vorteilhaft, eine weitere Aufnahmevorrichtung 6 zu verwenden, so daß eine kontinuierliche Arbeitsweise auch dann geboten wird, wenn die Aufnahmevorrichtung 5 gefüllt ist. Die Aufnahmevorrichtungen 5 und 6 sind beweglich, d.h. entweder mit Hilfe von an diesen angeordneten Rädern aus der Entladestation 4 entfernbar oder durch eine an die Entladestation 4 heranfahrbare Maschine heraushebbar.In addition to the transport device 3 according to FIG. 1, the device 4 according to the invention for taking over and storing the folded products 1 delivered by the transport device 3 is shown. This comprises at least one receiving device 5 in which the folded products 1 taken over by the transport device 3 are stored. It is advantageous to use a further receiving device 6, so that a continuous mode of operation is offered even when the receiving device 5 is filled. The receiving devices 5 and 6 are movable, i.e. either removable from the unloading station 4 by means of wheels arranged thereon, or lifted out by a machine that can be moved to the unloading station 4.

Die Aufnahmevorrichtungen 5 und 6 weisen jeweils mindestens eine Haltevorrichtung 7 bzw. 8 auf, die in dem hier beschriebenen Ausführungsbeispiel in der Arbeitsposition schräg geneigt sind. Es können mehrere, nebeneinander angeordnete Haltevorrichtungen in Form von Stangen oder Stäben verwendet werden.The holding devices 5 and 6 each have at least one holding device 7 or 8, which are inclined obliquely in the working position in the exemplary embodiment described here. A plurality of holding devices in the form of rods or bars arranged next to one another can be used.

An den Enden 7', 7" läuft eine umlaufende Transportvorrichtung 9, beispielsweise an einem Band oder einer Kette, vorbei. Auf einem Telweg ist dieser Transportvorrichtung 9 eine zweiteilige elektrische Leitung 10,11 zugeordnet. Diese dienen zur zeitgerechten Erregung und Entregung von im Abstand voneinander an der umlaufenden Transportvorrichtung 9 befestigten Elektromagneten 12. Die Elektromagnete 12 sind jeweils mit einem Schleifschuh 13 ausgerüstet, der wie bei 14 angedeutet z. B. durch Kippen, in Kontakt mit den elektrischen Leitungen 10, 11 gebracht werden kann. Hierfür eignet sich ein Einführungstrichter 15, der kurz vor der Halterung 8 zu positionieren ist. Zur Rücksteuerung der Schleifschuhe 13 und somit zur Entregung der jeweils mit diesen verbundenen Elektromagnete 12 sind Auslauftrichter 26 und 27 geeignet, die kurz vor den Enden 7' und 8' der Halterungen 7 und 8 angeordnet sein müssen. Dadurch wird erreicht, daß die Elektromagnete 12 kurz vor dem Ende 8" erregt und kurz vor dem Ende 7' bzw. 8' entregt werden, je nachdem, ob die Aufnahmevorrichtung 5 oder die Aufnahmevorrichtung 6 verwendet wird.At the ends 7 ', 7 ", a rotating transport device 9 runs past, for example, a belt or a chain. A two-part electrical line 10, 11 is assigned to this transport device 9 by telecommunication. These are used for timely excitation and de-excitation at a distance Electromagnets 12 fastened to each other on the rotating transport device 9. The electromagnets 12 are each equipped with a grinding shoe 13 which, as indicated at 14, can be brought into contact with the electrical lines 10, 11, for example by tilting Introductory funnel 15, which is to be positioned shortly in front of the holder 8. To back-control the grinding shoes 13 and thus to de-energize the electromagnets 12 connected to them in each case, discharge funnels 26 and 27 are suitable, which shortly before the ends 7 'and 8' of the holders 7 and 8 must be arranged. This ensures that the electromagnets 12 "shortly before the end 8" and shortly before the end 7 'or 8' are de-energized, depending on whether the receiving device 5 or the receiving device 6 is used.

Die umlaufende Transportvorrichtung 9 wird über Führungsrollen 16 bis 24 in der in Fig. 1 dargestellten Weise geführt und beispielsweise durch die Rolle 24 angetrieben, die mit einem entsprechenden Antrieb 32 versehen ist. Die Rolle 23 wirkt als Spannrolle für die Transportvorrichtung 9. Den einzelnen Leitungsabschnitten 10, 11 sind separate Ansteuerklemmen zugeordnet, die mit 10' und 11' bezeichnet sind.The rotating transport device 9 is guided over guide rollers 16 to 24 in the manner shown in FIG. 1 and driven, for example, by the roller 24, which is provided with a corresponding drive 32. The roller 23 acts as a tension roller for the transport device 9. The individual line sections 10, 11 are assigned separate control terminals, which are designated by 10 'and 11'.

In erfindungsgemäßer Weise werden in der Entladestation 4 vorzugsweise flache Falzprodukt-Transportelemente verwendet. Die Falzproduktelemente bestehen aus magnetisierbaren Blechen 28. Es ist jedoch auch ausreichend, nur bestimmte Bereiche der Transportelemente magnetisierbar auszubilden. Auf den Halterungen 7 in der Aufnahmevorrichtung 5 bzw. auf den Halterungen 8 in der Aufnahmevorrichtung 6 werden die von den Enden 7' bzw. 8' eingeführten Transportbleche 28 nebeneinander positioniert, in der Weise, daß beispielsweise durch eine leichte Neigung der Halterungen 7 und 8 diese von links nach rechts rutschen in Richtung der Enden 7" und 8". Da die Transportbleche 28 auf den Halterungen 7 und 8 dicht nebeneinander liegen, ist es erforderlich, jeweils an diesen nichtmagnetische Abstandsstücke 29 vorzusehen, wie in Fig. 2 angedeutet ist. Die Halterungen 7 und 8 sind jeweils mittels eines Vibrators 30 in Schwingungen versetzbar, so daß das Gleiten der Transportbleche 28 nach rechts noch begünstigt wird. Erreicht ein nichtmagnetisches Teil, beispielsweise in Form einer nichtmagnetisierbaren Platte 31, das rechte Ende 7" bzw. 8", so wird angezeigt; daß die jeweilige Aufnahmevorrichtung 5 bzw. 6 gefüllt ist. Nunmehr kann kein Transportblech 28 mehr an einen der am Ende 7" bzw. 8" vorbeilaufenden Elektromagnet 12 übergeben werden. Wie in Figur 1 angedeutet ist, können die Elektromagnete 12 an den Enden 7" oder 8" ein Transportblech 28 von den Halterungen 5 oder 6 übernehmen und in einer Aufwärtsbewegung dieses jeweils zwischen ein gespreizt auf den Transportstäben 2 ankommendes Falzprodukt 1 einführen, um dieses zu übernehmen. Es versteht sich, daß nach Übernahme eines Falzproduktes 1 seitlich die Transportstäbe 2 aus demselben herauszuziehen sind. Gegebenenfalls könnte auch durch eine entsprechende Führung der Transportvorrichtung 9 weiter nach oben ohne Bewegung der Transportstäbe 2 die Übergabe erfolgen.In the manner according to the invention, flat folded product transport elements are preferably used in the unloading station 4. The folded product elements consist of magnetizable sheets 28. However, it is also sufficient to use only certain areas of the Training transport elements to be magnetizable. On the brackets 7 in the holding device 5 and on the brackets 8 in the holding device 6, the transport plates 28 inserted from the ends 7 'and 8' are positioned side by side in such a way that, for example, by a slight inclination of the brackets 7 and 8 these slide from left to right towards the ends 7 "and 8". Since the transport plates 28 lie close together on the brackets 7 and 8, it is necessary to provide non-magnetic spacers 29 on each of them, as indicated in FIG. 2. The brackets 7 and 8 can each be set in vibration by means of a vibrator 30, so that the sliding of the transport plates 28 to the right is further promoted. If a non-magnetic part, for example in the form of a non-magnetizable plate 31, reaches the right end 7 ″ or 8 ″, it is displayed; that the respective receiving device 5 or 6 is filled. Now it is no longer possible to transfer a transport plate 28 to one of the electromagnets 12 passing at the end 7 ″ or 8 ″. As indicated in FIG. 1, the electromagnets 12 can take over a transport plate 28 from the holders 5 or 6 at the ends 7 "or 8" and, in an upward movement, insert them between a folded product 1 arriving on the transport rods 2 in order to feed them take over. It goes without saying that after taking over a folded product 1, the transport bars 2 are to be pulled out of the same laterally. If necessary, the transfer could also take place by correspondingly guiding the transport device 9 further up without moving the transport rods 2.

Nun werden die jeweils auf einem Transportblech 28 liegenden Falzprodukte 1 durch die Transportvorrichtung 9 zum Ende 7' der Halterung 7 oder zum Ende 8' der Halterung 8 geführt, je nachdem, welche der Aufnahmevorrichtungen 5 oder 6 beladen wird. Wird die Aufnahmevorrichtung 5 beladen, so muß die Führungsrolle 18 in die ausgezogen dargestellte Position verschwenkt werden, bei der unter Entregung des jeweils ankommenden Elektromagneten 12 durch den Auslauftrichter 27 die Übergabe des Transportbleches 28 mit dem auf diesem befindlichen Falzprodukt 1 an die Halterung 7 erfolgt. Vorzugsweise sind jeweils die Enden der Halterungen 7', 7" bzw. 8', 8" leicht nach oben gebogen. Beim Beladen der Aufnahmevorrichtung 5 muß die Führungsrolle 20 von der Aufnahmevorrichtung 6 weggeschwenkt werden. Beim Beladen der Aufnahmevorrichtung 6 hingegen wird die Führungsrolle 18 in die gestrichelt dargestellte Position und die Führungsrolle 20 ebenfalls in die gestrichelt dargestellte Position gebracht. Dadurch ergibt sich, daß die Transportbleche 28 an der Aufnahmevorrichtung 5 vorbei zu den Enden 8' der Halterungen 8 der Aufnahmevorrichtung 6 bewegt werden und, nachdem nicht der Auslauftrichter 27, sondern erst der Auslauftrichter 26 die Elektromagnete 12 entregt, folgt die Übergabe der Transportbleche 28 und somit der auf diesen hängenden Falzprodukte 1 an das Ende 8' der Halterung 8. Durch entsprechende Spannungsbeaufschlagung der Leitungsabschnitte 10 bzw. 11 wird der Beginn der Erregung der Elektromagnete 12 bzw. der Einfluß derselben festgelegt, so daß wiederum in Abhängigkeit von der Beladung der Aufnahmevorrichtung 6 oder der Aufnahmevorrichtung 5 entweder die Transportbleche 28 von der Halterung 8 oder von der Halterung 7 abgenommen werden.Now the folding products 1 lying on a transport plate 28 are guided through the transport device 9 to the end 7 'of the holder 7 or to the end 8' of the holder 8, depending on which of the holding devices 5 or 6 is loaded. If the receiving device 5 is loaded, the guide roller 18 must be pivoted into the position shown in the solid line, in which the discharge plate 27 with the folded product 1 located thereon is de-energized by the discharge funnel 27 by excitation of the incoming electromagnet 12 to the holder 7. Preferably, the ends of the brackets 7 ', 7 "and 8', 8" are slightly bent upwards. When loading the receiving device 5, the guide roller 20 must be pivoted away from the receiving device 6. When loading the receiving device 6, however, the guide roller 18 is brought into the position shown in dashed lines and the guide roller 20 is also brought into the position shown in dashed lines. The result of this is that the transport plates 28 are moved past the receiving device 5 to the ends 8 'of the brackets 8 of the receiving device 6 and, after the discharge funnel 26 does not de-energize the electromagnets 12, the transfer of the transport plates 28 follows and thus the folding products 1 hanging thereon at the end 8 'of the holder 8. The voltage applied to the line sections 10 and 11 respectively determines the start of the excitation of the electromagnets 12 and the influence thereof, so that again depending on the loading of the Receiving device 6 or the receiving device 5, either the transport plates 28 are removed from the holder 8 or from the holder 7.

In Fig. 3 ist eine Beladestation, die auch zum Entladen einsetzbar ist, dargestellt, die im grundsätzlichen Aufbau mit der Entladestation gemäß Fig. 1 übereinstimmt. Deshalb wurden gleiche bzw. gleichwirkende Teile mit den gleichen Bezugszeichen versehen wie in Fig. 1. Mit der Vorrichtung gemäß Fig. 3 sollen in Speichern bzw. Aufnahmevorrichtungen 33 und 35 vorhandene auf Transportblechen 28 hängende Falzprodukte 1 auf die Transportvorrichtung 3 übertragen werden, d.h, es ist eine umgekehrte Arbeitsweise wie bei der Vorrichtung gemäß Fig. 1 erforderlich. Einen wesentlichen Vorteil bietet die erfindungsgemäße Magnetanordnung. Die Verwendung als Beladestation ist möglich, wenn die Bleche neigbar sind, so daß sich die Exemplare öffnen. Nach Abgabe der Falzprodukte 1 von der Aufnahmevorrichtung 33 bzw. wenn diese geleert ist von der weiteren Aufnahmevorrichtung 35 an die Transportstäbe 2 der Transportvorrichtung 3, die sich bei der Anordnung gemäß Fig. 3 von rechts nach links bewegt, müssen die leeren Transportbleche 28 wieder gesammelt werden, wofür weitere Aufnahmevorrichtungen 34 und 36 verwendet werden. Wenn die Aufnahmevorrichtung 33 geleert wird, gelangen die Transportbleche 28 jeweils in die Aufnahmevorrichtung 34 und wenn die Aufnahmevorrichtung 35 geleert wird, gelangen diese in die Aufnahmevorrichtung 36.FIG. 3 shows a loading station which can also be used for unloading, the basic structure of which corresponds to the unloading station according to FIG. 1. For this reason, the same or equivalent parts have been provided with the same reference numerals as in FIG. 1. With the device according to FIG. 3, folding products 1 hanging on transport plates 28 and stored in storage devices or receiving devices 33 and 35 are to be transferred to the transport device 3, ie a reverse procedure as in the device according to FIG. 1 is required. The magnet arrangement according to the invention offers a significant advantage. It can be used as a loading station if the sheets can be tilted so that the specimens open. After delivery of the folded products 1 from the receiving device 33 or when the latter is emptied from the further receiving device 35 to the transport rods 2 of the transport device 3, which moves from right to left in the arrangement according to FIG. 3, the empty transport plates 28 must be collected again are used for which further receptacles 34 and 36. When the receiving device 33 is emptied, the transport plates 28 each get into the receiving device 34 and when the receiving device 35 is emptied, they get into the receiving device 36.

Wie bereits im Zusammenhang mit der Beschreibung der Fig. 1 erwähnt wurde, sind in jeder der Aufnahmevorrichtungen 33, 34, 35, 36 jeweils eine oder mehrere Halterungen 37, 38, 39, 40 vorgesehen, die in der bereits beschriebenen Weise geneigt sind. Beim Entleeren des Speichers bzw. der Aufnahmevorrichtung 33 werden die Elektromagnete 12 durch Beaufschlagung der Steuerleitung 10' mit einer Spannung erst an der Aufnahmevorrichtung 33 erregt, so daß sie jeweils ein Transportblech 28 mit einem Falzprodukt 1 übernehmen. Danach erfolgt in einer Aufwärtsbewegung die Heranführung an die Transportstäbe 2 der Transportvorrichtung 3, wobei eine Spreizung der Falzprodukte erfolgt durch eine entsprechende Neigung der Bleche, wie in Fig. 1 angedeutet ist, so daß die Transportstäbe 2 seitlich leicht einführbar sind. Nunmehr können die Transportbleche 28 durch die Transportvorrichtung 9 unter Entregung an dem Auslauftrichter 42 abgegeben werden an die Aufnahmevorrichtung 34.As already mentioned in connection with the description of FIG. 1, one or more brackets 37, 38, 39, 40 are provided in each of the holding devices 33, 34, 35, 36, which are inclined in the manner already described. When emptying the memory or the receiving device 33, the electromagnets 12 are only energized by applying a voltage to the control line 10 'at the receiving device 33, so that they each take over a transport plate 28 with a folded product 1. Thereafter, in an upward movement, the transport rods 2 of the transport device 3 are brought up, the spreading of the folded products being effected by a corresponding inclination of the sheets, as indicated in FIG. 1, so that the transport rods 2 can be easily inserted laterally. Now they can Transport plates 28 are delivered to the receiving device 34 by the transport device 9 with de-excitation at the outlet funnel 42.

Soll die Aufnahmevorrichtung 35 entleert werden, so erfolgt die Erregung der Elektromagnete 12 bereits am Einauftrichter 41, wobei die Leitung 11 durch eine Spannung, die an den Anschluß 11' angelegt wird, aktiviert wird. Die Übergabe der Falzprodukte 1 an die Transportstäbe 2 erfolgt in der zuvor beschriebenen Weise, wonach die Transportbleche 28 wiederum an einen Auslauftrichter 43 unter Entregung der Elektromagnete 12 an die Aufnahmevorrichtung 36 abgegeben werden. Um die gewünschte Bewegungsbahn für die Transportvorrichtung 9 zu erhalten, sind Führungsrollen 44, 45, 46, 47, 48 vorgesehen. Je nachdem ob die oberen Aufnahmebehälter 33 und 34 oder die unteren Aufnahmebehälter 35 und 36 verwendet werden, müssen die Führungsrollen 46 und 48 im ersten Fall, in die jeweils ausgezeichnete und im zweiten Fall in die gestrichelt dargestellte Position geschwenkt werden. Wie bei 49 und 50 angedeutet, sollten auch die Enden der Halterungen 37 bis 39 nach oben gebogen werden.If the receiving device 35 is to be emptied, the electromagnets 12 are already energized at the inlet funnel 41, the line 11 being activated by a voltage which is applied to the terminal 11 '. The folded products 1 are transferred to the transport bars 2 in the manner described above, after which the transport plates 28 are in turn delivered to an outlet funnel 43 with de-energization of the electromagnets 12 to the receiving device 36. In order to obtain the desired movement path for the transport device 9, guide rollers 44, 45, 46, 47, 48 are provided. Depending on whether the upper receptacles 33 and 34 or the lower receptacles 35 and 36 are used, the guide rollers 46 and 48 in the first case must be pivoted into the respectively excellent position and in the second case into the position shown in broken lines. As indicated at 49 and 50, the ends of the brackets 37 to 39 should also be bent upwards.
