摘要:
System for continuous change of reels (15) made of corrugated cardboard (50), supplying packaging machines; an extensible container compartment (20), made up of protection elements (25, 26), arranged to close the supply section which starts from the reel unwinding area; the protection elements (25, 26) expand, so as to define a variable volume loading reservoir and increase the capacity thereof in the step of accumulating the cardboard corresponding to the step in which the reel is about to finish; pressing means hold the final strip of the unwound cardboard in an end joining area while sealing means (90) allow the joining of the final strip of the unwound cardboard with an identical strip of another replacement reel, replaced in the meanwhile.

A label paper processing apparatus is provided which can meet with a requirement for production of a large variety and small lots of label products, such as not to impose a large burden on manufacture of the products in terms of cost and delivery time therefor, which facilitates controlling in half-cutting of label paper and in which feeding label paper to travel can easily be controlled. The apparatus comprises a paper supply means 3, a digital printing means 4, a laser processing means 5 and a pair of loop forming means 8 disposed between the paper supply means 3 and the digital printing means 4 and between the digital printing means 4 and the laser processing means 5, respectively, each forming a loop of the label paper. The digital printing means 4 is used to print a print image and a cutting locus, thereby meeting with a requirement for production of a large variety of and small lots of label products, thereby not to impose a large burden on a manufacturer in terms of cost and delivery time therefor. The laser processing means 5 is designed to half-cut the printed label paper and to form cutouts of a shape along the printed cutting locus with a laser beam irradiated so as to scan and trace the printed cutting locus, thereby facilitating control in half-cutting of label paper. The loop forming means 8 designed to form a loop of the label paper which is held substantially constant all the time makes it simplified to control feeding the label paper to travel.

Die Erfindung betrifft eine Vorrichtung (10) zur spannungsfreien Speicherung von bahnförmigem Material (60), mit einem Materialeinlauf (11) mit einer das Material (60) kontinuierlich zuführenden Zuführvorrichtung (12), einem Materialauslauf (13) mit einer das Material (10) kontinuierlich ausführenden Ausführvorrichtung (14) und einer endlos umlaufenden Fördervorrichtung (20) für das Material (60) mit wenigstens zwei durch die Fördervorrichtung bewegbaren Traggliedern (21) wobei das Material (60) über die Tragglieder (21) geführt ist und zwischen benachbart angeordneten Traggliedern (21) jeweils eine Schlaufe (61) ausbildet und die Tragglieder fest mit der Fördervorrichtung verbunden sind und ein gesteuerter Vorschub der Fördervorrichtung (20) vorgesehen ist und der Vorschub anhand der Menge an zugeführtem Material und/oder der Länge der in einem Zwischenraum zwischen den Traggliedern (21) ausgebildeten Schlaufe (61) steuerbar ist sowie ein Verfahren zum Befüllen einer Vorrichtung (10) zur Speicherung von bahnförmigem Material (60).
摘要:
This hot-marking machine (1) comprises a marking member (6) intended to press a tape (7) against the peripheral surface (2A) of individual parts (2) in order to mark them, said individual parts (2) being positioned in succession in a marking station and being marked by the repetition of a marking sequence for each part. The machine (1) comprises means (12-14) for unwinding the tape, intended to unwind a length of tape (7) sequentially at the end of each marking sequence, for the next marking sequence, and means (15-17) for rewinding the tape. The machine (1) further includes a tape suction box (18) and a tape braking surface (19A), the braking surface (19A) being of fixed orientation relative to the frame (3) of the machine (1) during each marking sequence, the tape (7) output by the unwinding means (12-14) passing in succession through the suction box (18), along the braking surface (19A) and facing the marking member (6), in such a way that a reserve of tape (7) is available in the suction box (18) between the unwinding means (12-14) and the braking surface (19A), while the tape (7) is tensioned, facing the marking member (6), between the braking surface (19A) and the rewinding means (15-17).
摘要:
The invention relates to an application device (10) for applying individual flat material segments (26), especially labels, to be separated from a flat material web (20), to products (P) that continuously move past the application device (10). The application device comprises a separation unit (50) for separating a flat material segment (22) from the flat material web (20) and an application unit (60) for applying the flat material segment (26) to the product (P). Between the separation unit (50) and the application unit (60) a buffer unit (70) is provided that decouples the separation process performed by the separation unit (50) from the application process performed by the application unit (60).
摘要:
The invention relates to a device for cutting paper webs. Said device comprises a paper feed device (102), a cutting device (108) and a paper delay device (106) which is located between the paper feed device (102) and the cutting device (108) and which delays the fed paper web (112) in such a way that a position is determined on the paper web (112) in which the cutting device (108) is to cut the paper web (112). A buffer device (104) is located between the paper feed device (102) and the paper delay device (106) to take up an accumulating length of the paper web (112) in the form of a loop whilst said web (112) is delayed. A control device (190) controls the paper feed device (102) and the paper delay device (106) in such a way that the height of the loop (195) taken up by the buffer device (104) does not fall below a minimum threshold (h).
