Definitions

• the present invention is in the field of industrial machines, and more particularly in the field of driving and maintenance of such machines.
• the invention relates to the control of industrial machines for the manufacture of different products that may require the change of dimensional parts from one product to another, for example tires.
• the invention aims to propose a solution for simplifying and securing these procedures.
• EP 2 942 717 which relates to a method of providing maintenance instructions to a user, is known in the field of maintenance of industrial machines.
• the method described in this document does not overcome the aforementioned drawbacks, related to the question of dimensional changes.
• the invention proposes a method of assisting the dimensional adjustment of an industrial machine, the machine being driven by an operator provided with a portable device provided with a microphone and a speaker, the device being connected to a remote server hosting a database and software means, the method comprising the following steps:
• the operator transmits, via the microphone, a voice assistance request concerning a step of a dimensional adjustment procedure of the machine, the request is analyzed by voice recognition means,
• the database is selected with a set of relevant data for the step to be performed,
• the relevant data is converted into an audible signal intelligible to the operator via voice synthesis means.
• the sound signal is transmitted to the operator via the loudspeaker.
• the step of an adjustment procedure may consist of different actions:
• the step to be performed is the change of a dimensional part present on the machine.
• the relevant data includes, for example, at least the identification of a part to be changed, and the identification of the replacement part.
• the identification of a part is a set of elements for example included in the group comprising: an identifier inscribed on the part, a part dimension, the name of a part, its location on the machine, its storage location in the factory.
• the step to be performed is the dimensional adjustment of one or more elements of the machine.
• some parts must be replaced, as indicated above, and some must simply be set to different values.
• the relevant data includes, for example, the identification of the workpiece to be adjusted, and one or more adjustment values to be applied.
• the identification of the part to be adjusted is a set of elements for example included in the group comprising: an identifier inscribed on the part, a part dimension, the name of a part, its location on the machine.
• the step to be performed is the verification of adjustment tolerances of the machine.
• the relevant data include, for example, acceptable tolerance values for one or more machine settings.
• the data also include a precise identification of the part on which the adjustment must be made, the term identification must here be understood as before.
• the step to be performed is the encoding of measured values after adjustment.
• the relevant data includes, for example, setting names.
• the assistance method includes a set of additional steps, during which:
• the operator transmits, in response to the sound signal representing the relevant data, an appropriate response,
• This response is analyzed by speech recognition means and transformed into formatted data to be stored in the database.
• the request transmitted by the operator is performed using words in a group of predetermined words and known speech recognition means.
• voice recognition means determines in advance a list of words that the voice recognition means must be able to recognize and associate with an action to be performed and a set of relevant data to select from the database and to transmit to the operator.
• These words can be of different types, such as for example:
• a method according to the invention may advantageously be implemented in a plant with different types of machine, each of them having parts, arrangements, dimensions ... particular.
• the step of selecting the relevant data in the database is performed not only according to the query, but also depending on the machine on which the operator is working.
• a method according to the invention comprises a preliminary step during which the operator initially transmits the identification of the machine on which he operates. In this case, which step of selecting relevant data in the database is performed according to the transmitted request, and the identification of the machine.
• FIG. 1 presents a simplified diagram of the means of implementation of FIG. a method according to the invention.
• Figure 1 shows an operator 1 equipped with an audio device 2.
• This audio device comprises means for capturing the voice of the operator, for example a microphone, and sound transmission means to the operator.
• the audio device is preferably portable, wireless, and insulating external noise. This characteristic is particularly important in industrial environments where the environment is very loud, because of industrial machinery. In an advantageous example, it is possible to use a device operating by bone conduction.
• This audio device also comprises wireless communication means, allowing it to exchange signals with software means 3 installed on a server of the factory.
• These software means 3 comprises, in the example:
• a software application 3 has voice recognition, - A software application 3b of speech synthesis, and
• a 3c software application for managing different scenarios is connected to a database 4 in which all the information relevant to the implementation of a method according to the invention is recorded.
• the operator requests the activation of the software means 3 by pronouncing a predetermined activation keyword.
• a change of dimension for example on a complex tire manufacturing machine, is a complex operation, which comprises a large number of tasks to be performed, among which : change of dimensional parts, machine settings, activation / deactivation of certain functionalities ...
• a method according to the invention makes it possible to perform such an operation in two different modes: a fully guided mode, where the software means indicate to the operator each of the steps to be performed; and an assisted mode, where the operator knows the steps, and only needs to receive details such as dimension values or settings.
• a fully guided mode where the software means indicate to the operator each of the steps to be performed
• an assisted mode where the operator knows the steps, and only needs to receive details such as dimension values or settings.
• the operator requests, by voice, setting values, for example by giving the phrase "roller width A”.
• the voice recognition means 3a analyze the received sound signal to understand the request received from the operator, and transmit the request to the management application 3c.
• This management application 3c retrieves from the database the relevant data to be transmitted to the operator.
• This relevant data is selected in the database according to parameters among which: the identification of the machine on which the operator works, the scenario chosen by the operator during the activation step, and the request of setting of the operator.
• the relevant data from the database are synthesized by the means 3b to be transformed into a voice signal understandable by the operator. It is specified here that the relevant data may concern not only values or a part identifier, but also information to guide the operator on the procedure to follow. When the operator has made the adjustment, he can confirm the good achievement by a predetermined validation word. He then asks for the next setting, and so on until he has done all the necessary operations for the chosen scenario.
• Another example of application of a method according to the invention is the performance of checks on the machine, type "check-list". As indicated in the preamble of this application, such verifications are for the moment carried out by hand by the operator.
• the operator initiates the desired scenario, and the software application 3c retrieves, in the database, the list of elements to be checked.
• the software means 3 then communicate each element, one by one, to the operator, which in return communicates the measured value. In this example, it is then possible to generate, by the software means, a summary report of the verification performed.
• a method according to the invention makes more ergonomic and more reliable all of the procedures of settings, measurements and encodings to be performed on a machine, including a machine manufacturing and / or tire assembly.
