Abstract

The invention relates to a device for removing shavings (7) during the trimming of the top and bottom edges of a stack of books or unbound books in a three-knife trimming machine, in which the parallel trimming knife (3) has assigned to it a dweller nozzle (5) which, when trimming has been completed, moves air towards the cutting edge of the parallel trimming knife and downwards, a rigid guiding device (6) which is connected to the parallel trimming knife (3) and encloses the strip-like shavings (7) on all sides being arranged at a distance from the cutting line of the parallel trimming knife. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Entfernen der Späne beim Kopf- und Fußbeschnitt eines Buch- oder Broschurenstapels in einer Dreimesserschneidemaschine, bei der dem Seitenmesser eine, nach erfolgtem Schnitt, gegen die Seitenmesserschneide und nach unten wirkenden Blasluftdüse zugeordnet ist.The invention relates to a device for removal the chips when cutting the head and foot of a book or Stack of brochures in a three-knife cutting machine, in which the side knife, after the cut has been made, against the side knife edge and acting downwards Blow air nozzle is assigned.

Beim Buch- oder Broschurenbeschnitt auf Dreimesser­ schneidemaschinen müssen die Späne, die beim Beschnitt des Schneidgutes durch die Vorder- und Seitenmesser an­ fallen, entfernt werden. When trimming books or brochures on a three-knife Cutting machines must remove the chips that are produced during trimming of the material to be cut by the front and side knives fall, be removed.  

Die Beseitigung der Späne, die durch Vordermesserbe­ schnitt entstehen, ist zufriedenstellend gelöst. Größere Probleme treten immer wieder bei der Beseitigung der Späne auf, die durch den Seitenmesserbeschnitt ent­ stehen.Removal of chips by front knives cut is solved satisfactorily. Bigger problems occur again and again during the elimination of the chips caused by the side knife trimming stand.

Es ist eine Lösung bekannt, bei der den Seitenmessern Blasluftdüsen zugeordnet sind, die so ausgebildet sind, daß sie die Späne von den Messern wegblasen.A solution is known in which the side knives Blow air nozzles are assigned, which are designed so that they blow the chips off the knives.

Diese Lösung hat den Nachteil, daß mit steigender Takt­ leistung der Dreimessermaschinen der Luftbedarf steigt und ein relativ hoher Geräuschpegel entsteht. Zusätzlich kommt es zu Verwirbelungen, so daß Restspäne in der Schneidstation bleiben, was zu Ungenauigkeiten beim Be­ schnitt des nachfolgenden Schneidgutes führen kann bzw. in seitlich angeordnete Transporteinrichtungen fällt, was zur Havarie führt.This solution has the disadvantage that with increasing clock performance of the three-knife machines the air requirement increases and there is a relatively high noise level. In addition There is turbulence, so that residual chips in the Cutting station remain, which leads to inaccuracies when loading cut of the following material to be cut or falls into laterally arranged transport devices, which leads to the accident.

In der DD-Patentschrift 2 59 128.8 ist eine Blasluftdüse beschrieben, durch welche die Verwirbelungen weitgehend eingedämmt werden sollen, doch bei im Hochleistungsbe­ reich arbeitenden Dreimesserschneidemaschinen ist die Wirkung stark eingeschränkt.In DD patent specification 2 59 128.8 there is a blowing air nozzle described by which the turbulence largely to be contained, but in the high-performance area is the richly working three-knife cutting machine Effect severely limited.

Ziel der Erfindung ist es, eine Vorrichtung so zu ge­ stalten, daß die anfallenden Späne mit optimalem Luft­ bedarf so entfernt werden, daß keine Behinderung des Schneidprozesses eintreten kann und die Bücher- oder Broschuren mit einer hohen Maßhaltigkeit beschnitten werden können.
The aim of the invention is to design a device so that the resulting chips with optimal air are removed so that no hindrance to the cutting process can occur and the books or brochures can be trimmed with high dimensional accuracy.

Aufgabe der Erfindung ist es, eine Vorrichtung zum Ent­ fernen der Späne beim Kopf- und Fußbeschnitt eines Buch- oder Broschurenstapels in Dreimesserschneidemaschinen zu schaffen, die ein sicheres und kontrolliertes ver­ wirbelungsfreies Beseitigen der Späne mit optimalem Luft­ bedarf ermöglicht.The object of the invention is to provide a device for Ent remove the chips when cutting the head and foot of a book or stacks of brochures in three-knife cutting machines to create a safe and controlled ver swirl-free removal of chips with optimal air needs enabled.

Erfindungsgemäß wird die Aufgabe durch die Merkmale der Patentansprüche 1 und 2 gelöst.According to the invention, the object is characterized by the features of Claims 1 and 2 solved.

Die Erfindung soll nachstehend an einem Ausführungs­ beispiel erläutert werden. Die zugehörigen Zeichnungen zeigenThe invention is intended to be an embodiment example will be explained. The associated drawings show

Fig. 1 die schematische Darstellung einer Seitenansicht der erfinderischen Vorrichtung, wobei sich das Seitenmesser oberhalb des Schneidgutes befindet, Fig. 1 is a schematic representation of a side view of the inventive device, wherein the side knives located above the cutting material,

Fig. 2 die schematische Darstellung, gemäß Fig. 1, bei der das Seitenmesser in Durchschnittsstellung ist, Fig. 2 shows the schematic diagram of FIG. 1, in which the side knives in average position,

Fig. 3 einen Schnitt durch Fig. 2. Fig. 3 is a section through FIG. 2.

Die Fig. 1 zeigt einen Schneidtisch 2 auf dem ein Schneid­ gutstapel 1 liegt. Dem das Seitenmesser 3 tragenden Messer­ träger 4 ist eine Leiteinrichtung 6 zugeordnet. Zwischen der Leiteinrichtung 6 und dem Seitenmesser 3 ist eine gegen die Seitenmesserschneide und nach unten blasende Blasluftdüse angeordnet. Fig. 1 shows a cutting table 2 on which a good stack 1 is lying. The knife carrier 4 carrying the side knife 3 is assigned a guide device 6 . Between the guide device 6 and the side knife 3 there is a blowing air nozzle which blows against the side knife edge and downwards.

Die Wirkungsweise der Erfindung ist folgende.The operation of the invention is as follows.

Bei Beginn des Schneidvorganges durch die Seitenmesser 3 beginnt die Blasluftdüse 5 zu blasen, dabei werden die Späne 7 durch die auf die Seitenmesserschneide blasende Düse vom Seitenmesser weggeblasen und durch die nach unten wirkenden Düsen in eine Absaugvorrichtung oder Vorratsbehälter geblasen.At the beginning of the cutting process by the side knives 3 , the blowing air nozzle 5 begins to blow, the chips 7 being blown away by the nozzle blowing on the side knife cutting edge and blown through the downwardly acting nozzles into a suction device or storage container.

Durch die, durch die Anordnung der Leiteinrichtung 6 am Messerträger 4 in einem optimalen Abstand zu dem Seitenmesser 3 entstehende allseitige Ummantelung der Späne 7 wird eine Verwirbelung dieser vermieden. Gleich­ zeitig werden durch die Leiteinrichtung 6 benachbarte Transporteinrichtungen abgeschirmt. Da die Unterkante der Leiteinrichtung 6 der Seitenmesserspitze vorauseilt beginnt die allseitige Ummantelung bereits bei Schnitt­ beginn.Because of the arrangement of the guide device 6 on the knife carrier 4 at an optimal distance from the side knife 3 , all-round sheathing of the chips 7 is avoided. At the same time 6 adjacent transport devices are shielded by the control device. Since the lower edge of the guide device 6 leads the side knife tip, the all-round sheathing begins at the beginning of the cut.

Zusätzlich erfolgt durch die allseitige Ummantelung eine optimale Luftausnutzung. In addition, due to the all-round sheathing optimal air utilization.
