摘要:
A force transducer, in particular a load cell, includes a spring body that deforms when loaded with a force or load to be measured. Two support parts, which are separated by a gap, are moved out of a position of rest. A capacitive displacement detector is used to detect the relative movement of the support parts, where the capacitor includes two electrode combs that are each held on one of the support parts and includes a multiplicity of electrode fingers. The electrode combs are configured designed and mounted on the two support parts such that the electrode fingers of the one electrode comb pass into the finger interspaces of the other electrode comb when the spring body is loaded so that the force transducer is resistant to overloading.

A method for testing a monitoring device (20) of an automatic labeling machine (10) for containers (12) for correct functioning, in the case of which, a specially marked measuring container (14) is fed thereto, upon whose detection, a labeling process is discontinued at least for this measuring container (14), and the measuring container (14) provided with markings (16) is scanned by at least one optical sensing device (21) of the monitoring device (20).
摘要:
A method and a device for inspecting containers and/or preforms. A scattering medium is provided in the interior of the containers or preforms and is irradiated in such manner that the scattering medium forms a bright field behind the container or preform wall area to be imaged. In this way, the wall area can easily be illuminated and imaged from different directions, so that inspection units can be created with a high degree of design freedom and with smaller dimensions.

Method of optical inspection of closures on containers in which the outer edge of a closure is illuminated obliquely from above over the full circumference, and a photograph of the top side of the closure is made perpendicularly from above, and this photograph is used to detect the outer edge of the mouth, which appears brighter, and to check on the position of the cover logo relative to this edge of the mouth either directly or indirectly, and a signal is generated in the event an unacceptable eccentricity is found.
摘要:
In a process for the optical inspection of at least partially transparent containers in an inspection area with an illuminating device and a camera for producing images to be evaluated, the degree of transparency of each container is determined, and a light field is configured for this specific container. The light intensity of the light field and/or the imaging sensitivity is adapted to the determined degree of transparency, and the traveling light field is shifted through the inspection area in synchrony with the container. The system for implementing the process has an LED light screen with a plurality of LEDs, which can be activated individually or in groups, and a device upstream of the inspection area for measuring the individual degree of transparency of each container. These components are connected to a control unit, which produces the traveling light field for each container and shifts it in synchrony with the container. The control unit also adapts the light intensity of the traveling light field to the degree of transparency found for the container in question.

Disclosed is a method and apparatus for correlating first and second signals where sampling values of the signals are multiplied together and discrete values of the correlation function are determined. In one embodiment, the signals are sampled at different sampling frequencies such that one sampling frequency is a multiple of the other sampling frequency. A number of the respective last sampling values of the more fully sampled signal are stored and each sampling value of the more rapidly sampled signal is multiplied simultaneously by all of the stored sampling values of the more slowly sampled signal. The results of the multiplication are separately summed corresponding to equal time displacements between the multiplied sampling values. In a further preferred embodiment, a microcomputer is programmed for sampling the two signals with sampling frequencies having a ratio 1:k. The more slowly sampled signals are stored in an n stage register. The contents of corresponding register stages are multiplied in n multiplier circuits by the sampling values of the more quickly sampled signal. A summation store having m=k.multidot.n storage locations stores the multiplication values and a distributing circuit introduces the multiplication values into the storage locations associated with the respective time displacements for addition to the preceding storage location content.
