Problems solved by technology

[0004] Problems can arise during high-speed production of filter seaming machines that the glue layer applied to the wrapping paper web is too thin, or leaks occur, or due to process-induced faults, such as contamination in the glue application system and form an interruption, so that a sufficient connection between the filter tip and the tobacco rod cannot be ensured

Embodiment Construction

[0027] In the following figures, the same or similar elements or corresponding components are provided with the same reference signs, except for correspondingly updated concepts.

[0028] figure 1 is a perspective view of the ultrasonic measurement system 10 . The ultrasonic measuring system 10 is designed in a fork or U shape. A wrapping paper strip 15 is passed and conveyed between the two legs of the U. The wrapping paper strip 15 is provided with a glue pattern coated with glue, which is applied to the wrapping paper strip 15 by a gluing mechanism, not shown here. The glue pattern has a plurality of glue-free areas 17 which are perforated by means of a processing mechanism after cutting the wrapper tape 15 into small packets and wrapping the cut packets around the filter tip and the tobacco rod.

[0029] The edge area is mainly used for bonding the cigarette wrapper to the cigarette rod. Lack of glue in these parts will cause the filter to loosen or fall off, so it is ...

Abstract

The invention provides a further possibility for detecting glue quantity or monitoring glue size applied to a wrapping strip, especially in marginal parts thereof, of the tobacco-processing industry, and for monitoring glued parts. The device has ultrasound measuring system (10) with at least two ultrasound producing sources for impinging ultrasound on the casing strip (15). At least two ultrasonic sensor receiving units (14) are provided for receiving ultrasonic signals which pass through the casing strip. A partition (21, 31) is arranged between at least two ultrasound producing sources or between at least two ultrasonic sensor receiving units. An independent claim is also included for the machine for tobacco processing industry.

Description

technical field [0001] The invention relates to a device for detecting and / or monitoring the quantity or quality of glue applied to wrapping strips in the tobacco processing industry, wherein an ultrasonic measuring system has at least two devices for applying ultrasonic waves to the wrapping strip 1. A wave source for generating ultrasonic waves and having at least two ultrasonic sensor receiving units for receiving ultrasonic signals penetrating the wrapping tape. Furthermore, the invention relates to a tobacco processing industrial machine. Background technique [0002] In order to connect the cigarette filter to the tobacco rod, a wrapper is usually provided. The wrapper wraps the filter on the one hand and connects the tip end of the tobacco rod to the filter on the other hand with a protruding edge. The filter tip and the tobacco rod are usually joined together by gluing. [0003] European Patent Application EP-A-1 147 716 describes a device for applying glue to wra...
