Definitions

• the subject of the invention is an element for displaying information which comprises a frame, rollers which are located some distance apart from each other in the frame, and a web on which the information is placed and which can be moved between the rollers where the information is visible. Identifying codes are located on the web for monitoring the movement of the web and a sensor device is located on the frame to observe the identifying codes, where the identifying codes are codes situated on the web, of which one code is the data code concerning the position of information on the web.
• Elements with changing information are used to display one or generally more notices, advertisements, publications or other display material in such traditional locations as external or internal sites in public or business premises, exhibitions, sports stadiums such as ice hockey rinks, fairs and presentation sites, by roadsides, at airports or in department stores.
• equipment is used in which the web is reeled from one roller to another by one roller pulling and the other roller rotating freely. Possible tensioning of the web is carried out using a sprung tensioning roller or with motors rotating in opposite directions.
• the purpose of this invention is to introduce an element which can be used to eliminate the drawbacks associated with present elements.
• the purpose of this invention is to introduce an element in which data concerning the speed, direction and distance travelled of the web, as well as the location of the information can be determined precisely and reliably, and which, when in use, can guide and control assemblies containing one or more advertising elements.
• one code or code group is for measuring the web speed, direction and distance travelled.
• This code is formed by signals located on the web some distance from each other, which the sensor device has been arranged to observe continually.
• the code concerning the location of the information is contained in a different code strip.
• These two code groups or strips can be used to monitor precisely and reliably the movement of the web, i.e. its speed, direction and distance travelled, on a continual basis since monitoring and measurement is taken direct from the web itself. This means that information can be brought into view for the desired period of time and the operation of the web can be monitored continually. With this equipment, information can be obtained concerning for how long certain information, such as an advertisement, has been displayed.
• the codes are number codes presented in the form of bar code strips, and the sensor device is an optical or electro-magnetic sensor. With this kind of arrangement the movement of the web can be observed reliably and the position of information on the web defined precisely.
• the number codes according to the invention are advantageously binary, BCD or hexacodes, or equivalent codes, of a particular length, which have had start and end signals added at the start and end. In this way the start and end positions of the web can be determined and the web can be stopped if necessary.
• the codes are advantageously situated such that they are in phase displacement to each other. This makes it possible to position the data correctly with the sensor device and to obtain precise and reliable data of the web section, in other words to know precisely the web section in question.
• figure 1 shows one element viewed from the front
• figure 2 shows the element in figure 1 , viewed from the rear and partly opened
• figure 3 shows an enlargement A of the element web according to figure 2, viewed from the side
• figure 4 shows a complete system incorporating elements according to the invention.
• the element according to figures 1 and 2 comprises a frame 2, which has a transparent window on one side 8.
• the frame contains two rollers 3 positioned some distance apart from each other, with one in the upper section and the other in the lower section of the frame.
• the element includes a web 4 containing the information, which can be wound onto the rollers and moved between the rollers.
• the rollers 3 are removable and can be easily changed in the normal manner to exchange the web for another. When the web is between the rollers the information at that position on the web can be seen through the window 8.
• the element includes motors 9 to rotate the rollers.
• There is a microprocessor 10 in the element 1 with which the element 1 can be regulated and controlled independently.
• the electronics are located in the case 11 behind the web, where they are easy to service.
• the case 11 contains the web 4 manual/automated guidance equipment and the forward/reverse switches with which the exchange and removal of the web 4 is made simple.
• the case 11 also contains the measuring sensor 7 forming the sensor equipment.
• the element frame is constructed from tubes and with plastic sheeting as protective panels.
• the window plastic is double or single layer plastic depending on the location where it is used.
• the bases of the motors 9 are attached to the end panels of the element.
• the motors 9 rotate the transmissions 12 which rotate the rollers 3.
• the number of motors rotating the rollers can be reduced by using the same motor to operate several elements.
• the code which comprises two code strips 5, 6, where one 5 is the so-called time signal and the other 6 is the web data signal.
• the codes in the code strip 5 are a short distance apart from each other along the whole length of the web. Every picture section on the web has as its highest point the centre mark 6a of the previous (higher) picture and number code 6b. At the lower edge of the picture section is the number code 6c for this picture section.
• the centre marks can be positioned either at the upper or lower edge of the picture section, depending on the location of the sensor and it is coded in a recognised way to observe the signal.
• the time signal is used to measure the direction of travel of the web, its speed and distance travelled.
• the data signal contains data on the web's stopping positions, the web code and details of every picture on the web.
• the number code is according to the application a certain length binary, BCD or hexacode or other series code, which has had start and end codes added to the start and end.
• the number code of the application shown in the figure is a 6 bit binary code, but longer codes are also possible.
• the time signal 5 and data signal 6 are in the desired phase displacement position with each other.
• the phase displacement is 90°, but it can vary with different applications.
• Every web has a specific web code from which can be identified the web being used and the specific picture code from which can be identified the picture in question. With this method, any incorrect positioning of the web as a result of power cuts or other faults can be remedied immediately.
• the stop signal on the edge i.e. the centre mark can be coded in a certain manner, so that it can be checked whether the signal is correct.
• the data signal is read on either the rising or falling edge of the time signal.
• the distance between the number code and the centre mark can change depending on the application. Also the code mark colours and sizes can alter.
• the time and data signals are read either optically or electromagnetically with the measuring sensor 7.
• the measuring sensor measures the length and speed of the web from the code signals 5 at certain distances on the web 4, and the web can be positioned wherever desired and its movement and speed monitored.
• On finding the picture code 6 the following time pulse is sought, after which the speed of the web is reduced and when the picture stop signal is observed the web is stopped. When a certain number of time pulses have come the picture stop signal should be found from the web. If it is not found it is moved forward.
• a computer 14 is used to control the elements, in which there is a programme which is used to control the communications network 15.
• the element or elements 1 are connected to the network and the microprocessors inside the elements are controlled via the network, through which the management of the elements is centralised and flexible.
• the motors of the elements are controlled by the microprocessors so that the webs can continually travel at the desired speed from end to end.
• the desired section of the web can be held in position and previously selected sections can be driven with the desired stop intervals.
• An advantage of the former is the minimisation of the mechanical parts of the element and the diverse application possibilities of the equipment. Many types of arrangements can be created from the elements according to the invention, such as for ice hockey rinks or other locations.
• the exchange of information-bearing web rollers for other types of information bearing web rollers is possible and easy.
