Description

DESCRIPTION
METHOD AND SYSTEM FOR MOVING ONE OR MORE PRODUCTS ALONG LOGISTIC PATHS IN AN INDUSTRIAL PLANT
Technical field
This invention relates to a method and a system for moving one or more products along logistic paths in an industrial plant.
The invention also relates to an industrial plant, a storage unit and an industrial line comprising the above-mentioned industrial system.
This invention also relates to a computer program.
In other words, the invention can be applied in the industrial automation sector.
Background art
Generally speaking, the term logistic paths in industrial plants means all those paths along which one or more products must travel including, for example, a production line and an industrial carriage, for example if these products must be loaded on the line or unloaded from it.
In particular, there are currently few methods which are actually efficient that allow a significant automation for the requested loading/unloading of the products from the line, also referring to requests made by voice between the various operators inside the industrial plant.
In a similar way, this process also occurs at a point of sale where, if a product is missing on a shelf, an operator would need to physically realise that there is a lack of the product and call a storekeeper to replenish the product.
It should be noted that these methods are not very efficient and can lead to bottlenecks inside the industrial plant which can reduce the overall efficiency of the plant. Solutions which have the above-mentioned drawbacks are described, for example, in the following prior art patent documents: US2021081886A1 , US2017323162A1 and US2014193227A1 .
The technical purpose of the invention is therefore to provide a method and a system for moving one or more products along logistic paths in an industrial plant which are able to overcome the drawbacks of the prior art.
Aim of the invention
The aim of the invention is therefore to provide a method and a system for moving one or more products along logistic paths in an industrial plant which are able to effectively automate the requests for moving the products inside the plant.
It should be noted that the term industrial plant means not only a production line but the entire industrial complex which may comprise, inter alia, storage units, loading bays, unloading bays, terminal for loading/unloading of earth moving machines (such as trucks).
A further aim of the invention is therefore to provide a method and a system for moving one or more products along logistic paths in an industrial plant which allow a high exchange of information inside a star network.
The technical purpose indicated and the aims specified are substantially achieved by a method and a system for moving one or more products along logistic paths in an industrial plant comprising the technical features described in one or more of the appended claims. The dependent claims correspond to possible embodiments of the invention.
According to an aspect of the invention, a method is provided for moving one or more products along logistic paths in an industrial plant. The method comprises a step of measuring a control parameter, representing a quantity of products present in an exchange terminal of the industrial plant. The method comprises a step of comparing between the measured value of the control parameter and one or more threshold values of the control parameter. The method comprises a step of generating a movement signal from the results of the comparison which respect at least one predetermined movement condition and as a function of the predetermined movement condition. The movement signal represents a type of movement between a picking up of products from the exchange terminal or a replenishment of products on the exchange terminal.
The method also comprises a step of sending the movement signal to at least one industrial carriage, a step of moving the industrial carriage towards the exchange terminal and a step of picking up products from the exchange terminal or a replenishment of products on the exchange terminal by the industrial carriage. It should be noted that, according to an embodiment which is simpler but more rapidly actuated, the invention comprises a method wherein the generation of the movement signal is started manually by a supervision operator, which manually monitors the control parameter. For example, the operator could select a button which starts the generation and sending of the movement signal.
Preferably, the movement step may be performed in an automated fashion by means of a unit for controlling the industrial carriage (or any other movement means involved in the method such as AGV, trucks or movable shelves) configured for actuating an actuator of the industrial carriage.
Preferably, the movement step may be performed manually by an operator or other technician for moving the carriage and/or the products.
According to another aspect of the invention, a system is provided for moving one or more products along a logistic path of an industrial plant comprising at least one transmitting device comprising at least one sensor configured for measuring a control parameter, representing a quantity of products present in an exchange terminal of the industrial plant and movement means, preferably an industrial carriage, configured to move one or more products along the logistic path and including an actuator, to allow a movement of the industrial means, that is, of the carriage, and at least one receiving device, configured to receive signals and to transmit them to the control unit of the movement means, that is, of the industrial carriage.
According to an embodiment, the transmitting device does not comprise a sensor but receives a signal representing the control parameter from a sensor which is part of the exchange terminal on which the transmitting device is implemented. In other words, the sensor is constrained to the exchange terminal for detecting a parameter linked to the exchange terminal and the transmitting device is connected to the sensor to receive a value of the control parameter, on the basis of which to generate and send the movement signal.
According to other embodiments, an industrial terminal may include a plurality of sensors, each associated with a respective zone or station of the industrial terminal. For example, the industrial terminal could comprise a first sensor, associated with a container for supplying the industrial terminal (for example at the infeed to a production line), and a second sensor, associated with a container for collecting the finished or semifinished product (for example, at the outfeed to a production line). In that case, each sensor (or the control unit of the industrial terminal) communicates with the transmitting device, to send a control signal including the type of control parameter, a value of the control parameter and the zone/station to which said value refers. The transmitting device implements variable control logics based on the zone/station to which the value refers.
Obviously, the control logics (that is, the step of comparing the control parameter) may be performed in the transmitting device, which is equipped with a relative processing unit, or in the control unit of the industrial terminal.
The system also comprises a processing unit, configured to receive the measured value of the control parameter, comparing the measured value of the control parameter with one or more threshold values of the control parameter, generating a movement signal, from the results of the comparison which comply with at least one predetermined movement condition and as a function of the predetermined movement condition, wherein the movement signal is representative of a type of movement between a picking up of products from the exchange terminal or a replenishment of products on the exchange terminal and sending the movement signal to the receiver device of the industrial carriage.
The industrial carriage (or the generic movement means) is configured to move or be moved to the exchange terminal to pick up products from the exchange terminal or to supply products on the exchange terminal as a function of the movement signal.
Preferably, the processing unit is configured to perform one or more of the steps of the method according to the invention.
Preferably, the at least one sensor configured for measuring a control parameter comprises or is made in the form of optical sensors, photocells, weight sensors and/or image capturing systems.
Preferably, the control parameter includes a weight value, a flight time of an optical signal and/or a space occupied, inside an image, by the products in the exchange terminal.
For example, if there are photocell sensors, these are positioned perpendicularly to a front for accumulating the material (for example perpendicular to the bottom of a container of pieces). In that way, the distance of the sensor from said storage front is representative of the number of pieces and can therefore start the generation of the movement signal for distances which are less than a threshold value (unloading requirement) or greater than a threshold value (replenishment requirement).
According to other embodiments, which can preferably be used when the objects are transferred on belts individually, it is possible to use a viewing system with integrated artificial intelligence, which makes it possible to recognise the products with image recognition algorithms and, consequently, to perform a count of the products. According to an aspect of the invention, the transmitting device is configured to send a movement signal representing a processing which is necessary at a specific point of the industrial plant. Thus, the device is not necessarily called for loading/unloading operations. For example, according to an embodiment, the transmitting device is configured to call a sealing machine, located in the industrial plant in a standby zone, in such a way that it reaches the industrial terminal to perform the specific sealing process.
According to another embodiment, the transmitting device could be positioned on a truck for transporting goods which arrives in an industrial plant. The acceptance associates with the truck a specific loading bay, on which a receiving device is positioned connected to a luminous actuator of the loading bay. The receiving device of the loading bay may receive an activation signal (which has been referred to as a movement signal but which, more generally speaking, is an activation signal), which actuates the luminous actuator, for example to indicate the loading bay to the truck or to indicate that the products in the loading bay have arrived.
Preferably, the transmitting device, the receiver device and the processing unit communicate with each other via a radio type communication.
Preferably, the radio communication is performed at a high coverage frequency of between 863 and 928 MHz.
Preferably, the radio communication is performed at a frequency of 868 MHz.
According to another aspect of the invention, an industrial plant is provided comprising a system configured for performing the method. The system comprises at least one industrial carriage configured for storing replenishment products.
According to another aspect of the invention, a storage unit is provided comprising a system configured for performing the method according to the invention. According to another aspect of this invention, an industrial line is provided comprising a system configured for performing the method according to the invention.
According to another aspect of the invention, a computer program is provided including instructions for performing the steps of the method according to the invention.
According to an embodiment, the computer program is stored at least in the processing unit.
According to an embodiment, the computer program is stored remotely. According to this embodiment it is a "SAAS (Software as a Service)” computer program, that is to say, configured to be implemented only in the presence of an Internet connection.
According to an aspect of the invention, the invention provides an industrial plant comprising a plurality of industrial terminals, comprising:
- a plurality of transceiver devices, configured for receiving and exchanging radio signals between each other and each associated with a corresponding industrial terminal;
- a plurality of sensors, each configured for measuring a respective value of a corresponding control parameter and for sending it to a corresponding transceiver device of said plurality, said plurality of sensors being integrated with one or more transceiver devices or being integrated with one or more industrial terminals.
Each transceiver device is configured for:
- receiving a control signal from the corresponding industrial terminal, representing a further transceiver device to which to send an activation (that is, movement) signal, or
- comparing the control parameter with a threshold value, for verifying compliance with an activation condition (movement) and, on the basis of said verification, generating the activation signal.
Each transceiver device is configured to start an actuator of the industrial terminal to which the device is associated for: - moving a loading/unloading means to the industrial terminal which sent the activation signal;
- switching on/starting an actuator of the industrial terminal associated with it, for example an illuminator or an audio emitter.
According to an aspect of the invention, each of said transceiver devices is configured to operate as an intermediate signal intensifying node. In particular, the activation signal comprises a unique code identifying the transceiver device to which the message is intended. Each transceiver device, upon receiving the activation signal, is programmed to derive the unique code and compare it with the relative unique code. If the unique derived code is the same as the relative unique code, the transceiver device reads the content of the activation signal and activates the corresponding actuator. If the unique derived code is not the same as the relative unique code (thus the message is not addressed to it), the transceiver device re-emits the activation signal, allowing even the most distant nodes to be reached. In this regard, it should be noted that each transceiver device is spaced from the device closest to it by a threshold value, less than 1200 m, preferably 1000 m.
In this way, this system is able to enable the communication on industrial plants which extend potentially without limits (that is to say, very long), working on the number of devices and their reciprocal arrangement.
With this type of structure, the industrial plant is able to communicate with industrial terminals which are even very distant from each other, thanks to the support of the intermediate nodes (devices).
Preferably, the radio communication occurs by means of a predetermined protocol, preferably on a frequency equal to 433 MHz, 868 MHz and/or 915 MHz. Preferably, the predetermined protocol is a protocol which uses an expanded spectrum modulation derived from the Chirp Spread Spectrum (CSS) modulation. Preferably, the predetermined protocol is the Lora ® protocol.
The use of the predetermined communication protocol allows communication even with loud background noise, which is a very likely context in an industrial plant.
Further features and advantages of the invention are more apparent in the non-limiting description which follows of a non-exclusive embodiment of a method and a system for moving one or more products along logistic paths in an industrial plant.

Detailed description of preferred embodiments of the invention
With reference to the accompanying drawings, the reference label "M" denotes in its entirety a method for moving one or more products "P" in an industrial plant 1 .
The term product "P" means any finished product or component for making a finished product which can be produced and/or stored in an industrial plant 1 .
The term industrial plant 1 may mean an industrial line (such as, for example, the one shown in Figure 2), a storage unit or a sales point. Alternatively, the industrial plant 1 is a building or a room comprising an industrial line, a storage unit or a point of sale (such as a supermarket and its shelves).
Inside or close to the industrial plant 1 there may also be at least one industrial carriage 3. Other features of the above-mentioned industrial plant are described in more detail below.
Preferably, the method "M" according to this invention is a method "M" for moving one or more products "P" in an industrial plant 1 performed in the form of, or comprising, an industrial line.
Preferably, the method "M" according to the invention is a method "M" for moving one or more products "P" in an industrial plant 1 made in the form of, or comprising, a storage unit or a point of sale.
The method “M” comprises a step F1 of measuring a control parameter, representing a quantity of products P present in an exchange terminal 2 of the industrial plant 1 (for example, the industrial line).
If the industrial plant 1 is made in the form of an industrial line (or comprises it), the measuring step "F1" comprises the measuring of the control parameter on one or more exchange terminals 2, defined by stations for loading or unloading the industrial line.
If the industrial plant 1 is made in the form of a storage unit or a sales point (or comprises them), the measuring step "F1" comprises the measuring of the control parameter on one or more exchange terminals 2, defined by shelving of the storage unit or of the point of sale.
Preferably, the measuring step "F1" is performed by optical sensors, photocells, weight sensors and/or image capturing systems.
Preferably, the control parameter includes a weight value, a flight time of an optical signal and/or a space occupied, inside an image, by the products "P" in the exchange terminal 2.
The method “M” also comprises a step “F2” of comparing between the measured value of the control parameter and one or more threshold values of the control parameter.
In other words, the comparison step "F2" is performed by checking that the control parameter is above or below the above-mentioned threshold values.
If the comparison shows that the control parameter falls within the threshold values, the method "M" would continue to perform the measuring "F1" and comparison "F2" steps.
If, however, the results of the comparison "F2" show that the control parameter is above or below a threshold value, the method "M" comprises generating "F3" a movement signal.
The movement signal is therefore generated by the results of the comparison which respect at least one predetermined movement condition and as a function of it.
For this reason, the movement signal represents a type of movement between the picking up of products "P" from the exchange terminal 2 or a replenishment of products "P" on the exchange terminal 2.
In other words, the generation "F3" comprises generating a pick-up movement signal if the control parameter is above a threshold value. This condition therefore identifies an excess of products "P" on the exchange terminal 2 which corresponds to a pick-up movement condition.
Moreover, the generation "F3" comprises generating a supply movement signal if the control parameter is below a threshold value. This condition therefore identifies a shortage of products "P" on the exchange terminal 2 which corresponds to a supplying movement condition.
The method "M" also comprises sending "F4" a movement signal to at least one industrial carriage 3.
The sending "F4" may be performed with reference to an automated industrial carriage 3 which therefore, in response to the signal, will pick up products "P" from the exchange terminal 2 or it will supply products "P" to the exchange terminal 2.
Alternatively, the sending may be performed by sending the signal to a control panel (installed on or close to the industrial carriage 3) or to a user interface device of a work technician who, after receiving the signal, will supply or pick up the products "P" from the exchange terminal 2.
Preferably, the step "F4" of sending the movement signal is performed by radio type communication. Preferably, the step “F4” of sending the movement signal is performed using a high cover frequency of between 863 and 928 MHz.
Even more preferably, the step "F4" of sending the signal uses a frequency of 868 MHz. Advantageously, the frequency of 868 MHz allows a high coverage to be obtained to exchange a large number of relative information items without limiting the data exchanged.
The method "M" also comprises moving "F5" the industrial carriage 3 towards the exchange terminal 2. The movement step "F5" may be performed by automated control of the industrial carriage 3 or by manual movement by an operator/technician.
Lastly, the method "M" comprises picking up or supplying "F6" the products "P" from or onto the exchange terminal 2 by the industrial carriage 3.
Advantageously, the method "M" allows a timely intervention if there is an excess or a shortage of products "P" on the exchange terminal 2.
Advantageously, the method "M" allows the control and management of the functions relative to the replenishment or picking up of the products "P" to be automated.

The industrial carriage 3 comprises an actuator for allowing a movement of the carriage and at least one receiver device 12 configured to receive the signals.
Preferably, the industrial carriage 3 also comprises a control unit, configured to instruct the actuator in the movement of the carriage. According to this embodiment, the receiver device 12 is configured for transmitting the signals to the control unit.
The term actuator may therefore mean a unit which can be actuated manually or automatically as a function of the embodiment of the industrial carriage 3 which allows the movement of the industrial carriage 3.
The system 10 also comprises a processing unit, configured to receive the measured value of the control parameter, comparing the measured value of the control parameter with one or more threshold values of the control parameter, generating a movement signal, from the results of the comparison which comply with at least one predetermined movement condition and as a function of the predetermined movement condition, wherein the movement signal is representative of a type of movement between a picking up of products “P” from the exchange terminal 2 or a replenishment of products on the exchange terminal 2 and sending the movement signal to the receiver device 12 of the industrial carriage 3.
In other words, the processing unit is configured for performing one or more of the functions of the method "M" according to the invention.
The industrial carriage 3 is configured to move or be moved to the exchange terminal 2 for picking up product from the exchange terminal 2 or supplying products to the exchange terminal 2 as a function of the movement signal.
Preferably, the transmitting device 11 and the receiver device 12 communicate with each other by radio type communication.
