Definitions

  • the present invention relates to a method and apparatus for measuring the dimensions, location, quality and/or other properties of paper, pulp, cardboard or plastic rolls and for marking the rolls with these data and/or for reading such markings in connection with rolls arranged in a row.
  • the measuring point may be located immediately after the winder, but it may also be disposed at a distance from it, in which case the roll sets are generally transferred to the measuring point by means of conveyors.
  • each roll is marked e.g. with a bar code by utilizing an ink jet printing technique, a sticker label or the like.
  • the minimum information given by the marking consists of an identifier which can then be used in the process control system to monitor/trace the passage of the roll. It is further necessary to ensure that the marking is readable and that the identifier corresponds to the physical quantities pertaining to the roll. This can be accom- plished e.g. by using a laser reader, a camera or by some other known method. Identification of the roll is additionally necessary when rolls are returned from an intermediate storage.
  • the measuring and marking operations on the rolls are carried out one roll at a time at separate stations reserved for them. Making the markings one roll at a time is a slow process and problems are often encountered in accommodating the equipment in cramped spaces. Measuring/marking equipment placed in separate stations require multiple conveying mechanisms and supporting structures for these, which leads to high costs. The measurements relating to quality control and the associated actions are generally carried out manually. This involves costs in the form of wages and safety arrangements.
  • Patent specification FI 104483B describes a method and arrangement for marking customer rolls after a winder.
  • the specification contains a detailed description of the operations performed after the winder.
  • the solution in question involves many limitations. According to the description given in the invention, only the dimensions of the roll are measured.
  • the measuring station is outside the rolling area.
  • the marking takes place at a fixed station which is used for nothing else. In other words, several working stations for the various operations and multiple structures are
  • the method of the invention is characterized by what is disclosed in the characterization part of the claims con- cerning the method.
  • the apparatus of the invention is characterized by what is disclosed in the characterization part of the claims concerning the apparatus.
  • a significant advantage provided by the invention is the fact that the required measuring and marking devices can be placed in conjunction with the equipment controlling the rolling motion of the rolls, utilizing its structures. Likewise, it is possible to utilize the movement of the motion control unit in the rolling direction of the rolls.
  • the operations according to the present invention can be carried out during the time when the motion control unit is free of duties relating to control of the rolling motion. Savings of space and time are achieved and multiple structures are avoided. Even if the measuring, marking and/or identifying units are arranged to be movable by a separate carriage unit, they can still share the same guide rails with the unit controlling the rolling motion.
  • the operations described can be carried out at several alternative positions within the framework of the operating range of the control unit. Also, possible later modifications of the working stations will be easy to implement. In many cases it is sufficient to add/transfer units and make the required changes in the control.
  • the method and apparatus of the invention can also be used at a roll measuring point separate from the slitter-winder functions.
  • An example of such use is the so-called trolley transport system, wherein the rolls are transported as roll sets, whereupon they are separated to be individually transported e.g. for packaging.

  • the operating power for the carriages 5 is obtained from a power means 9, preferably a geared motor, engaging a shaft 10. Mounted on the shaft 10, which is supported with bearings at one end of the guide rails 7, are transmission sprockets 11. Mounted with bearings at the other ends are deflecting pulleys 13. Power transmission is preferably implemented using cogged belts 12, whose ends are secured to the carriages 5 and which pass around the transmission sprockets 11 and the deflecting pulleys 13.
  • the apparatus comprises two carriages 5, two guide rails 7 and two belt drives 11 , 12, 13, one of each being disposed on either side of the rolling area, preferably above the rolls 1.

  • the combination of the carriages 5, the bracket 4 and the contact element 3 forms a unit controlling the rolling motion and is abbreviated as control unit 14.
  • the positions of the contact element 3 at different stages are referred to as P1 - P7.
  • the process may be e.g. as follows.
  • the control unit 14 When receiving a roll set 1 at position P1 , the control unit 14 re- cedes in front of the roll set 1 at a speed lower than the rolling speed of the roll set 1 , which therefore catches up with the control unit 14.

  • the control unit 14 conveys the rolls to position P4.
  • the actions typically comprise measuring the location of individual rolls in the direction of their axis of rotation and/or the diameter as well as the width of the roll in the manner described below. These measurement data are used to control a conveyor C1 moving in the direction of the axis of rotation of the roll set, which conveyor moves the rolls further according to the location data to a further process stage, e.g. to a roll packaging stage. Utilizing the location and/or measurement data, the rolls are marked with identification data before being moved further.

  • the power means 15, e.g. pneumatic cylinders raise the bracket 4 with the contact elements to a high position. Thus, it will not hit any rolls that may still remain on the conveyor C1 during the return movement.

  • the location of the rolls is now measured and/or the rolls are identified and registered by reading the identification marking, and possibly a verification quantity, such as the diameter and/or width, is measured.
  • An advantageous place for implementing both the measuring, marking and reading operations is the pick-up point of conveyor C1.
  • the marking on the circumferential surface can be read at the pick-up point C1 from the same rotary angle position at which the marking was made.
  • the measurement data can be used both for associating the identification data with the rolls and for arranging the rolls e.g. for transfer to a packaging machine.
  • Another advantageous point for the measurement and marking of the rolls is before conveyor C1 , e.g. position P3, in which case the previous set or a part of it may be on the conveyor C1 and after the conveyor has delivered that set, the entire new marked set can be moved onto the conveyor and then conveyed immediately further.

Abstract

L'invention concerne un procédé et un dispositif permettant de mesurer les dimensions, l'emplacement, la qualité et/ou d'autres propriétés de rouleaux de papier, de cellulose, de carton ou de plastique, et de les marquer et/ou de lire des inscriptions que comportent des rouleaux placés sur une rangée. Ces opérations peuvent avoir lieu au bobinoir ou à une certaine distance de celui-ci ; dans ce dernier cas, les rouleaux sont transférés vers le point de mesure par des transporteurs. Ces opérations ne nécessitent aucun poste de travail séparé. Une poutre guide (23), parallèle à l'axe d'enroulement de l'ensemble rouleau (1) et reliée à des chariots (5) qui se déplacent le long de rails de guidage (7) s'étendant sensiblement dans le sens de l'enroulement, guide au moins un élément mobile (24) comprenant un bras vertical (25). Un groupement d'unités informatiques fixé à ce bras peut comprendre une unité (26) de contrôle de la qualité, une unité de mesure (27), une unité de marquage (28) et une unité de lecture (29).
