Definitions

• the object of the invention is a method of verifying the correct positioning of rodlike articles with simultaneous correction of their arrangement in trays or intermediate stores used in the tobacco industry, and a device enabling the verification of correct positioning of rod-like articles in trays or intermediate stores and aligning of their front face.
• EP 2.079.327 Al belonging to the holder of the present invention, where the rod-like articles are conveyed from the tray to multiple segments separated from each other by vertical division walls, which are then emptied independently on each other through a throat formed at the base of the store, where both the intermediate store and the base with the throat independently of each other make reciprocating motions along the receiving conveyor so as to enable meeting of successive segments with the throat, and the sequence of emptying the segments is backward to the direction of receiving the articles on the conveyor.
• Said articles are fed onto the conveyor via a chute, which is permanently connected to the throat, where the throat of the surface area corresponding to the surface area of the horizontal section of a segment of the intermediate store receives articles each time from one, successive segment, and complete emptying of a segment is monitored by means of a sensor.
• the tray filling unit may jam, the consequence being that not all segments are correctly filled with rod-like articles.
• the arrangement of rod-like articles may be distorted, which would result in their suspension, and in effect a disturbance of the emptying process.
• the production process has to be interrupted as quickly as possible in order to remove the irregularities, and for their detection serve sensors situated in different places of the tray or the store.
• a method of verifying and improving the positioning of rod-like articles in trays or intermediate stores used in the production lines of the tobacco industry where a verification of positioning of the articles is effected by means of sensors, and an improvement of positioning of the articles is effected by aligning the plane of end faces of the articles, consists in verifying and improving the positioning of rod-like articles simultaneously be means of one aligning device provided with sensors, where the sensors detect the correct filling and/or arrangement of rod-like articles, and the aligning device levels the plane of end faces of the articles correctly filling the inside of the tray or the intermediate store.
• Such method ensures that the trays being filled have verified and corrected arrangement of articles, owing to which unloading of the tray will not be disturbed by improper arrangement of front faces of the articles.
• the aligning device In case of detection of incorrect filling and/or arrangement of rod-like articles by sensors, the aligning device is switched off and the operation of the unit, on which the aligning device is mounted, is interrupted. In this way the flow of articles to the tray, which will be later rejected from production, is interrupted, owing to which the number of rod-like articles of full value rejected from production is limited because each improperly filled tray is removed from the production. It is of particular importance in a modern production line where, on average, the trays contain 4000 articles each, and the production output amounts to more than 16000 articles per minute, so that the loading or emptying cycle of one tray lasts about 15 seconds. The above information applies equally to intermediate stores.
• the substance of the invention constitutes also the structure of a device enabling the verification of correct positioning of rod-like articles and aligning of their end face in trays or intermediate stores used in production lines of the tobacco industry, where the verification is effected by means of sensors controlling the filling level of a tray or an intermediate store, and aligning consists in aligning the plane of end faces of rod-like articles by their axial shift.
• an aligning device is made of a plate coming in contact with end faces of rod-like articles, provided with at least one sensor serving for the control of filling of a tray or an intermediate store.
• Said plate may consist of multiple pushers whose number corresponds to the number of segments of a multi-segment tray or an intermediate store, and a gap between the pushers corresponds to the thickness of a partition between the segments, with at least one sensor being situated on each pusher.
• the sensors may constitute an optical element operating in the range of visible radiation or invisible radiation, or may constitute an ultrasonic element.
• movable gates eliminating the gap are placed between the pushers.
• An advantage of the device according to the invention constitutes the possibility to check the correct filling of trays or intermediate stores with rod-like articles, where simultaneously the front face of an entire layer of articles is aligned to one plane, and, if irregularities in arrangement or filling are detected, filling or emptying may be interrupted and removed from the production line.

• fig. 10 an incorrectly filled multi-segment tray in the top view using a verifying device provided with ultrasonic sensors.
• the apparatus constitutes an aligning device J_, having a front plate 2 coming in contact with end faces of rod-like articles 3.
• the plate 2 is divided into multiple pushers 4 whose number corresponds to the number of segments 5 of a multi-segment tray 6 or an intermediate store 7, where a gap 8 between pushers 4 corresponds to the thickness of a partition 9 between segments 5.
• Each of the pushers 4 of the plate 2 has at the top a slant wall 10 which facilitates aligning of axially protruding rod-like articles 3 in the course of vertical movement in the tray 6 or the intermediate store 7 being loaded or emptied.
• movable gates ⁇ connected by a common slat 12 shifted horizontally by an actuator 13 are situated, with the gates ⁇ . having the shape corresponding to a vertical section of the plate 2. If conventional trays 6_1 or intermediate stores 1 with one compartment are used, the slat 12 is shifted forwards in order that the gates ⁇ fill the gap 8 between the pushers 4, making the plate 2 a monolith.
• sensors 14 of the axis perpendicular to the aligning plane are situated, where preferably each pusher 4 is provided with at least one sensor 14.
• the sensors 14 may constitute an optical element, operating in the range of visible or invisible radiation which detects the absence of rod-like articles 3 in a tray 6 or 61 or in an intermediate store 7 or 71, respectively, whereas for locating improperly arranged rod-like articles 3 ultrasonic sensors 14 are used. It is obvious that each pusher 4 may be simultaneously provided with both kinds of sensors 14.
• the device 1 is situated horizontally, preferably in the upper part of the unit loading the articles 3 to trays 6 or 61 or to stores 7 or 71, respectively, and may be also situated in the bottom part of the unit emptying the trays 6 or 61 or the stores 7 or 71, respectively.
• the aligning device I making constantly and uniformly a reciprocating motion in a plane parallel to the axis of the articles 3, provisionally aligns by means of the slant wall 10, and then by means of the plate 2, the front face of successive layers of rod-like articles 3.
• the sensors 14 check the correctness of filling or arrangement of the articles 3, and in case of detection of improper positioning or filling, the operation of the unit is stopped.
