摘要:
Die Erfindung betrifft ein Verfahren zum Betrieb einer Lebensmittelaufschneidevorrichtung, in der eine Sensoreinrichtung mit einem Sensor vorgesehen ist, wobei mit einem Schneidmesser ein auf einer Schneidauflage aufliegendes Lebensmittelprodukt aufgeschnitten wird. Das Verfahren dient dazu, den Betrieb des Schneidmessers zu optimieren und zu überwachen. Dies wird dadurch erreicht, dass mittels der Sensoreinrichtung eine Schneidkraft bestimmt wird, die von dem Schneidmesser über das Lebensmittelprodukt auf die Schneidauflage aufgebracht wird.
摘要:
During the machining of workpieces, in particular dynamic loads act on the cutting tools in addition to the static loads. This leads to chipping at the cutting edges of the cutting elements and thus to the destruction of the cutting element with the possible consequence that the workpiece is damaged and thus becomes useless. Furthermore, bending and torsional forces act on the cutting tools, and these bending and torsional forces load the machine tool and cause a change in position of the cutting tool, thereby resulting in defective machining of the workpieces. Furthermore, vibrations and chatter phenomena impair the machining of the workpieces. It is therefore proposed according to the invention that piezoceramic transducers (22, 30) be arranged in the region of the cutting tools (3), where force components of the cutting force act on the transducers. The signals produced by the forces acting on the transducers are directed to the control device of the machine tool and the machining of the workpieces is controlled with regard to these signals.
摘要:
A laser welding system for sealing or cutting polymeric sheets is described. The system comprises a laser source capable of delivering a laser beam. The laser beam is projected onto a region of the polymeric sheets where the sealing or cutting is to be performed. An optical device is provided to image the sealing or cutting as it is performed. An image analyser asserts the sealing or cutting quality. An integrated control means is provided to control the laser source, the projection of the laser beam, the optical device and the image analyser.
摘要:
A lower guillotine cutter blade (2) is mounted to a frame (1). A guillotine cutter-blade holder (3) holds an upper guillotine cutter blade (4) and vertically reciprocates with respect to the lower guillotine cutter blade (2). Rods (6) are vertically slidably mounted to the guillotine cutter-blade holder (3). A pressing plate (5) is secured to the lower ends of the rods (6). Springs (7) are fitted around the rods (6) between the guillotine cutter-blade holder (3) and the pressing plate (5) for downwardly elastically biasing the rods (6) so that the heads (6a) of the rods are kept abutted against the guillotine cutter-blade holder (3). In a cutting operation, after the pressing plate (5) is brought into abutment with a batch of paper (20), the guillotine cutter-blade holder (3) is further downwardly moved, thereby causing the lower and upper guillotine cutter blades (2 and 4) to cut the batch of paper (20) and also causing the heads (6a) to upwardly protrude from the guillotine cutter-blade holder (3). At this time, a sensor (8) mounted to the guillotine cutter-blade holder (3) detects the distance to the heads (6a). A thickness measuring element (27) determines the thickness of the batch of paper (2) on the basis of the detection signal.
摘要:
A sensing mechanism (12) for detecting user contact with an active portion (26) of the power tool (10) is provided. In addition, a safety mechanism (14) for preventing prolonged user contact with the active portion (26) of a power tool (10) is provided. The safety mechanism (14) is configured to actuate upon receipt of a signal from the sensing mechanism (12). According to a first aspect, the safety mechanism (14) is arranged to rapidly displace the active portion (26) away from a user extremity. Alternatively, according to a second aspect, the safety mechanism (14) is arranged to rapidly urge an extremity of the user away from the active portion (26) of the power tool (10).
摘要:
A cutter system for cutting a larger sheet (11) into individual photographic images (52) includes a cutter (28, 30) for severing a transverse strip containing one or more printed images (52) from a larger sheet (11). A transport table (12) positioned to receive the strip from the cutter (28, 30) includes two sets of drivers (20, 24), one set for moving the strip longitudinally and a second set for moving the strip laterally to a second cutter (30) that in turn separates the strip into individual photographs (52). Sensors (27, 29) in both cutters (28, 30) acting in response to fiducial marks (60, 61) on the larger sheet (11) cooperate with the drivers (20, 24) for positioning the larger sheet (11) and the severed strip at the proper cutting locations.
