Abstract

The device for cleaning press rolls is used in independent press systems or in machines with integrated single-sheet pressing by press rolls. The aim of the invention is to prevent damage to the folded sheets by paper waste, that is to say paper fibres, paper residues, powder and filler proportions of the paper and also thread residues in the case of thread-sealing units, adhering to the press rolls. The object consists in cleaning these foreign bodies from the surfaces of the press rolls. According to the invention, on each press roll a scraper is arranged which extends over the entire length of said press roll and acts against the direction of rotation of the press rolls. This scraper may be designed as a brush or plate-shaped metal or non-metallic body and is arranged so as to be readjustable. The foreign bodies removed by means of the scraper are caught in a vessel so that they do not fall onto the folded sheet again. <IMAGE>

Description

Die Einrichtung zum Reinigen von Preßwalzen wird in selbständigen Preßwerken bzw. bei Maschinen mit integrierter Einzelbogenpressung durch Preßwalzen eingesetzt.The device for cleaning press rolls is independent Presses or in machines with integrated single sheet pressing used by press rolls.

Bei bogenverarbeitenden Maschinen fallen während des Maschinenlaufes durch die Perforation oder beim Einstich der Nadeln von Fadensiegelaggregaten Papierbutzen, d. h. Papierfasern, Papierreste, Puder und Füllstoffanteile des Papieres sowie Fadenreste an, die mit den Falzbogen mitgefördert werden. Diese Fremdkörper bleiben beim Betrieb der Maschinen an den Preßwalzen haften. Bei jeder Walzenumdrehung werden sie durch den hohen Druck der Preßwalzen in die zu pressenden Falzbogen eingedrückt und führen zur Beschädigung der Falzbogen. Im extremen Fall können diese Teilchen sogar eingestanzt werden.In sheet-processing machines fall while the machine is running through the perforation or when the needles are inserted Thread sealing units, paper slugs, d. H. Paper fibers, paper scraps, Powder and filler parts of the paper as well as thread residues which are also conveyed with the folded sheets. These foreign objects stick to the press rollers when the machines are in operation. At every roll revolution they become due to the high pressure of the press rolls pressed into the folded sheets to be pressed and lead to Damage to the folded sheets. In extreme cases, they can Particles can even be punched.

Ziel der Erfindung ist es, eine Beschädigung der Falzbogen durch auf den Preßwalzen haftende Fremdkörper zu verhindern.The aim of the invention is to damage the folded sheet to prevent foreign bodies adhering to the press rolls.

Die Aufgabe der Erfindung besteht darin, die Oberflächen der Preßwalzen von Fremdkörpern zu reinigen.The object of the invention is the surfaces of the Press rollers to clean foreign bodies.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß an jeder Preßwalze ein über deren gesamte Länge reichender Abstreifer, welcher gegen die Drehrichtung der Preßwalzen wirkt, angeordnet wird. Dieser Abstreifer kann als Bürste oder platten- bzw. kammförmiger metallischer oder nichtmetallischer Körper ausgebildet sein. Zum Ausgleich eventueller Abnutzung ist er nachstellbar angeordnet. Die mittels des Abstreifers entfernten Fremdkörper werden in einem Behälter aufgefangen, damit sie nicht wieder auf die Falzbogen fallen. Damit wird eine Qualitätsminderung der Falzbogen, verursacht durch an den Preßwalzen anhaftende Teilchen, vermieden.According to the invention this object is achieved in that at each Press roll a stripper extending over its entire length, which acts against the direction of rotation of the press rolls, arranged becomes. This scraper can be a brush or a plate or comb metallic or non-metallic body formed be. It can be adjusted to compensate for any wear arranged. The foreign bodies removed by means of the scraper are caught in a container so they don't open again the folded sheets fall. This will reduce the quality of the Folded sheet caused by adhering to the press rolls Particles, avoided.

Die Erfindung wird an zwei Ausführungsbeispielen näher erläutert. In der zugehörigen Zeichnung zeigen: The invention is explained in more detail using two exemplary embodiments. In the accompanying drawing:  

Fig. 1 die Reinigungseinrichtung mit einer Bürste in Prinzipdarstellung Fig. 1 shows the cleaning device with a brush in a schematic representation

Fig. 2 die Reinigungseinrichtung mit einem Abstreifer in Prinzipdarstellung Fig. 2 shows the cleaning device with a scraper in a schematic representation

An einem nicht dargestelten Gestell sind die Preßwalzen 1 und 5 nach bekannten Lösungen fest oder verstellbar gelagert. Entgegen ihrer Drehrichtung ist ein über die gesamte Länge der Preßwalzen 1 und 5 reichender Abstreifer 2; 6 angeordnet. In Fig. 1 ist dieser als Bürste ausgebildet. Der Abstreifer 6 in Fig. 2 kann mit einer Stellschraube 7 eingestellt werden. Die Falzbogen 4 werden zwecks Pressung zwischen den Preßwalzen 1 und 5 hindurchgeführt. Von den Falzbogen 4 mitgeführte Fremdkörper wie Papierbutzen oder Fadenreste gelangen auf die Oberflächen der Preßwalzen 1 und 5. Diese Fremdkörper werden von den Abstreifern 2 und 6 abgestreift und fallen in den Behälter 3. Nach Erfordernis wird dieser von der Bedienperson entleert.On a frame, not shown, the press rolls 1 and 5 are fixed or adjustable according to known solutions. Contrary to their direction of rotation is a scraper 2 extending over the entire length of the press rolls 1 and 5 ; 6 arranged. In Fig. 1 this is designed as a brush. The scraper 6 in Fig. 2 can be adjusted with an adjusting screw 7 . The folding sheets 4 are passed between the press rolls 1 and 5 for the purpose of pressing. Foreign bodies such as paper slugs or thread remnants carried along by the folded sheets 4 reach the surfaces of the press rolls 1 and 5 . These foreign bodies are stripped off by the wipers 2 and 6 and fall into the container 3 . If necessary, it is emptied by the operator.
