Abstract:
Disclosed are a sheet punching apparatus and a method for controlling the same in which the side end position of a sheet, its rear end position, a hole position, and the detachment state of a punch portion are sensed only by two sensors, and a punching hole can be formed at the exact position of a sheet by means of the two sensors. The sheet punching apparatus includes a punch portion (120) moving in a direction perpendicular to a moving direction of a sheet, a bracket (122) having an elastic member (12) to move in conjunction with the punch portion (120), a sheet side end sensing means (S10) fixed to a predetermined position of the bracket, sensing the side end of the sheet in accordance with movement of the bracket, and a sheet rear end sensing means (S20) opened to sense the rear end of the moving sheet when the bracket moves at a predetermined distance along with the punch portion to sense the side end of the sheet, wherein the punch portion (120) works to punch the sheet at a predetermined position after the rear end of the sheet is sensed by the sheet rear end sensing means.
Abstract:
A slicing and conveying system (28) forms a three or more flavor-combined draft. Slicing machine slice a succession of first slices in the form of shingled draft side-by-side (A, B, C, D) on an output conveyor (180). An overlap conveyor merges side-by-side shingled drafts into an elongated combined draft. Sensors (192, 194) determine the lengths of the side-by-side drafts and the combined drafts. A control receives input from the sensors and outputs a control signal to the output conveyors to adjust the spacing of the slices.
Abstract:
Die Erfindung betrifft ein Verfahren zum Aufschneiden von Lebensmittelprodukten mit ungleichmäßiger Innenstruktur, wie z.B. Wurst oder Schinken, bei dem die Produkte (11) in Scheiben (S) geschnitten und insbesondere geschindelte Portionen oder Stapelportionen gebildet und aus dem Aufschneidebereich (31) abtransportiert werden, und bei dem während des Aufschneidens mittels einer optoelektronischen Erfassungseinrichtung in aufeinanderfolgenden Erfassungsvorgängen (E) Informationen über die Kontur und die Struktur der Produktscheiben gewonnen werden, indem der Aufschneidebereich ausgeleuchtet und von den Schnittflächen (13) der jeweils vom Produkt abzutrennenden Scheiben und aus dem Randbereich (15) der Scheiben reflektierte Ausleuchtstrahlung nachgewiesen und ausgewertet wird, wobei in wenigstens einem und bevorzugt in jedem Erfassungsvorgang (E) die Ausleuchtung in mehreren richtungsunabhängigen Komponenten (k) durchgeführt wird, die sich zumindest hinsichtlich eines Ausleuchtparameters voneinander unterscheiden. Die Erfindung betrifft außerdem eine Aufschneidevorrichtung, die insbesondere zur Durchführung eines derartigen Aufschneideverfahrens geeignet ist.
Abstract:
A method and apparatus (10) for cutting a graphics area (42a) from a sheet (40) of material which also includes a plurality of registration marks (44) at and about the graphics area in predetermined positions. The method involves steps to ascertain the position and orientation of the sheet as placed on the apparatus, sensing the locations of the marks at the time of cutting, and cutting the graphics area from the sheet along a path determined in response to the sensed positions of the marks with respect to graphics area at that time. Certain embodiments use either (a) a subset (46) of marks which is applied on one side of graphics area or (b)certain reference features (49), such as edges and corners of the sheet and elements of the graphics area, to ascertain the position and orientation of the sheet on the apparatus. The invention provides rapid, automated, and precise cutting despite two-dimensional distortion of the sheet.
Abstract:
The invention relates to a method for feeding a sample or a cutting knife into the cutting plane of a microtome, especially the cutting plane of a disc microtome, via a feeding carriage. According to the inventive method, the feeding carriage is moved and fed to a surface sensor by means of a motor drive. The position of the motor drive is determined and compared to a stored position of the cutting plane when the sample surface contacts the surface sensor. Control signals for the motor drive are calculated from both position values. The feeding carriage is fed into the cutting plane by means of the motor drive and in view of said control signals.
Abstract:
A fluid jet cutting system for simultaneously making multiple cuts in a continuously moving layered web of paper or nonwoven material. The fluid jet cutting system includes a controller (96) which monitors the web speed through an encoder feedback signal, and controls the travel speed and angle based on parameters stored in the controller memory and feedback signals. The user can select a cut length and other cutting parameters through an input device to the controller. Nozzles (16) are mounted to a drive system (12) including an adjustment device which allow fast easy and accurate adjustment of cut length.
Abstract:
A method for detection of false positive condition that an object is in contact with an implement in a power tool includes sampling an electrical signal received from the implement, identifying in-phase and a quadrature components of the sampled electrical signal, identifying a magnitude of each of the samples with reference to the in-phase component and the quadrature component for the samples, detecting an object approaching the implement with reference to the plurality of samples, identifying a signal-to-noise ratio for the samples, and identifying a false positive condition for the detected object with reference to the identified signal-to-noise ratio for the identified samples.
