Definitions
- the present invention relates to a control system for loading and unloading or movement of goods. It applies, in particular, to all companies, public or private organizations using the transport of goods in handling or packaging units or any other container that can be handled in the same way as a container support such as a pallet ( handling by pallet truck).
- container support or "pallet” used in this document covers any type of goods whether or not contained in containers that can be handled by a fork-lift machine (manual or electric pallet truck, forklift, stacker, etc. ..), it can be wooden pallets, plastic pallets, metal pallets, pallet boxes (wood, plastic, cardboard, wire mesh) ...
- One of the aims of the invention is to automatically trace the movements of goods during the loading and unloading phase.
- a prior art consists in using a laser beam bar code reader.
- the disadvantages of this technique are that the reading area must be less than 1 meter in height, bar code reading is unreliable (of the order of 30% of unread bar code) and there is no no proof of loading or unloading
- Another technique consists in using a portable terminal with barcode reader type PDA (for Personal Digital Assistant, in English terminology or personal digital assistant in French, also called an organizer).
- PDA Personal Digital Assistant
- the disadvantages of this technique are that it is not guaranteed that the identification of the container support is done before loading (the container support can be loaded and not identified), it is necessary to pause to identify the carrier of goods, and also there is no proof of loading or unloading.
- the invention can be extended from the automatic traceability of the movements of goods during the loading and unloading phase, to the movements of goods during their movements from one warehouse to another, and to the movements of stocks in general.
- the present invention aims to remedy these drawbacks with a completely innovative approach.
- the present invention relates to a system for controlling the loading and unloading or movement of goods comprising a terminal positioned near the point of passage of the goods, said goods being in containers, each container having a bar code or a container support comprises a bar code, said system being remarkable in that the terminal comprises:
- a camera-type taking device configured for taking a photo or film when at least one container passes in front of said terminal, said terminal extracts and decodes the bar code identifying the container (s) ( s) before sending said photo or said film to a database;
- control unit comprising a microcontroller controlling the system and said database, a photo or film processing unit to identify the bar code taken in a photo or film, a unit for triggering the taking of a photo or film in function of at least:
- the first detection cell comprising a first diffusion sensor and a second diffusion sensor indicating a passage in front of the terminal
- the second detection cell having a first reflection sensor and a second reflection sensor, cooperating with a reflector positioned on the container (s) or the or the container support (s) or a container support handling device indicating the presence of at least one container at the terminal.
- Diffusion sensors are installed in a single terminal, the transmitter and the receiver both being in the same housing. Diffusion sensors use the reflection of the target object within the predetermined detection range. The emitter sends out a continuous beam of light. Once it hits the target, it is scattered all over the place. Some of this light comes back and is recognized by the receiver which then sends an electrical signal to the output. Alternatively, background suppression diffusion sensors are used which utilize an adjustable sensing distance. In this case, objects with a reflective background are ignored to ensure that only objects included in the detection distance are detected. The information is then processed by the control unit.
- the system makes it possible to automatically trace the movements of goods or containers of goods or the like:
- the system is reliable in identifying everything on a container support passing nearby.
- proximity is meant a distance of less than 20m.
- Automatic identification consists of performing the following operations: [0016] - Automatically read the identification bar code of the container or of the container support without stopping the machine handling the container support (pallet truck, handling trolley, etc.), there is a continuous reading.
- the system makes it possible to identify with certainty and proof by the photo or film the movements of containers or supports of the containers carried out within the framework of precise operations (loading / unloading of a truck, transfers of stock, transfer of zone etc ).
- the system makes it possible to detect with certainty and proof by the photo or film the movements of containers or supports of the multiple containers pushed one behind the other, or superimposed on one another.
- the reflection sensors are installed in a terminal and the transmitter and the receiver are in the same housing. It is therefore sufficient simply to position the reflector facing the sensor. In the present case, the reflector is positioned on the handling machine. The principle is that a detection takes place when the light beam between the emitter and the receiver is received. The reflector returns the light beam to the sensor when an object is present which makes it possible to receive the beam and causes the sending of an electrical signal by the sensor to the output. The information is then processed by the control unit.
- the system can be easily installed anywhere in a warehouse or workshop: no need for square meters to install a terminal.
- the system of the present invention also makes it possible to identify the container (package) and container support (pallets) and their characteristics at a distance greater than 40 cm and up to several meters (which again gives the flexibility in material flows, and give agility and flexibility to material flows).
- the system of the present invention makes it possible to flash a container support which is in motion.
- the system of the present invention is flexible, it also does not impose a maximum width or length of the loaded packages. Unlike the systems of the state of the art, there is a maximum dimension in which packages or pallets fit.
- the system of the present invention is compatible and adaptable to each installation context (nature of sensor recognition, nature of the physical measurement elements), for example with the use or not of RFID, with the use or not of cameras, with the use or not of bar code readers, with the use or not of camera or camera.
- the invention is advantageously implemented according to the embodiments and the variants set out below, which are to be considered individually or according to any technically operative combination.
- the unit for triggering the taking of the photo or film takes the photo or film if the first diffusion sensor indicates the presence of a passage in front of the terminal to the control unit, then the second diffusion sensor indicates a passage past the terminal to the control unit.
- the unit for triggering the photo or film taking takes the photo or film if the second diffusion sensor indicates a passage in front of the terminal, then the second reflection sensor indicates the presence of at least one container or container support, then the first diffusion sensor indicates a passage in front of the terminal, then the first reflection sensor indicates the presence of at least one container or container support.
- it comprises at least one system information screen.
- it may include a second system information screen intended for the operator or his management giving him quantitative and qualitative information on the status of unloading or loading. (State of progress, compliance with safety and transit instructions, deadlines, time, percentages etc.)
- the screen makes it possible to show the photo taken or film during the loading and unloading or zone transfer of a container or of a container support.
- a terminal on each side of the crossing point of at least one container or container support is a terminal.
- a first depth sensor adapted to measure at least one distance in height of the container or containers between said first sensor and the container (s).
- a second depth sensor and a third depth sensor on either side of the passage point of at least one container or container support is a second depth sensor and a third depth sensor, the second depth sensor and the third depth sensor being adapted to measure at least a distance in length and width of at least one container or container support between the second sensor and the container (s) or container support, or the third sensor and the or the container (s) or container support.
- the system makes it possible to automatically determine the volume of air in the containers on the container support (maximum exterior dimensions: length, width, height), without stopping the device handling the container support.
- the various measurement sensors will measure all of the containers and will be able to reconstruct the volume of the assembly in three dimensions.
- the control unit will process the information from the various sensors to subtract the person handling the machine and the handling machine so that only the volume of the containers remains.
- the processing of information from the sensors is possible by knowing the direction and the direction of the container support, which facilitates the calculation of the volume to allow reliable identification of the handling machine and the person who uses it. manipulate.
- said system comprises a communicating terminal having a camera device and an element for sending said shots to said database.
- the communicating terminal is, for example: a digital tablet, a mobile phone, in particular of the “smartphone” type, a connected watch, connected glasses, a helmet, a computer, or a virtual reality helmet, or a digital screen in all its forms.
- a digital tablet for example: a digital tablet, a mobile phone, in particular of the “smartphone” type, a connected watch, connected glasses, a helmet, a computer, or a virtual reality helmet, or a digital screen in all its forms.

- One of the problems solved by the invention consists in guaranteeing the triggering of one or more photos or films at the exact moment of the passage of the container or of the container support in front of the terminal 20.
- the original idea is to use two container detection cells or the container support (direct reflection) to determine the direction of passage (one cell then the other), to measure the time between the two detections, calculate the speed of passage and trigger the photo or film at the precise moment of the passage of a container or the container support.
- the use of a third sensor also makes it possible to calculate the acceleration in addition to the speed.
- the cells When leaving the empty cart (without container support), the cells detect the order of passage and inhibit the triggering of a photo or film.
- the cells are positioned about 30 cm from the ground so as to be able to detect a container or a lower container support.
- FIG. 2 represents a diagram of the passage of a container support in front of a terminal 20 of the loading and unloading control system or of zone transfer of a container support.
- the implementation of the system results in the installation of terminals 20 at the level of the truck loading dock, it is also the installation of terminals 20 at the level of access doors to stocks ( example: products or goods leaving production on a container support or a container and then stored in a warehouse integrated on the site, the transfer is done by forklift).
- stocks example: products or goods leaving production on a container support or a container and then stored in a warehouse integrated on the site, the transfer is done by forklift).

- the control unit processes the direct information and calculates the speed of movement of the container support.
- the speed information is then processed by the photo or film triggering unit to trigger the photo or film at the right time.
- the photo or film is taken if the first diffusion sensor 23 indicates a passage past terminal 20 to the control unit and then the second diffusion sensor 24 indicates a passage past terminal 20 to the control unit.
- the photo or film is taken as a function of the speed of advance of the container support and if the first diffusion sensor 23 indicates a passage in front of terminal 20 to the control unit then the second diffusion sensor 24 indicates a passage past terminal 20 to the control unit.
- FIG. 5 represents the triggering of the photo or film centered on the container support.
- the unit for triggering the taking of the photo or film triggers the taking of the photo or film when the container support is at the environment of the cone shown in the figure.
- the medium is known by the speed of movement of the container support.
- the dimensions of the container support are known, the photo or film taking is triggered slightly (depending on the speed) after the outputs of the first diffusion sensor 23 and of the second diffusion sensor 24 indicate a passage in front of the terminal 20.
- the cut-off order of the first diffusion sensor 23 then of the second diffusion sensor 24 clearly indicates the loading and therefore the taking of a photo or film for the loading or transfer of the zone.
- FIG. 6 represents the loading of the container support in the truck or transfer to the area.
- the container support is loaded into the truck.
- the first diffusion sensor 23 and the second diffusion sensor 24 not being cut by the container support or by its handling device.
- FIG. 7 represents the exit of the carriage (handling equipment) of the truck.
- the container support is stored in the truck and we see the handling machine out of the truck.
- the handling machine is detected as follows: detection by the second diffusion sensor 24 then by the first diffusion sensor 23. In this detection order there is no photo or film trigger. In other words, when the second diffusion sensor 24 is cut and then the first diffusion sensor 23, the photo or film taking trigger unit does not take a photo or film.
- the handling system is first detected and certainly the operator if it is an electric or manual pallet truck.
- FIGs 8 to 11 show diagrams of the passage of the container support in front of a terminal 20 of the control system during unloading of the container support.
- terminal 20 is shown, a first diffusion sensor 23, a second diffusion sensor 24, first reflection sensor 27 and second reflection sensor 28.
- FIG. 8 represents the arrival in front of the identification zone and the detection of the operator.
- the container support is unloaded into the truck.
- the second diffusion sensor 24 is cut as well as the second reflection sensor 28.
- the second reflection sensor 28 does not return the reflection information since the reflector is on the handling machine.
- the operator walks past the detection cells without triggering them.
- FIG. 9 represents the detection of the handling device.
- the handling machine is detected by the second reflection sensor 28.
- the reflector positioned on the handling machine gives the information of the passage in front of the terminal 20.
- the first reflection sensor 27 is not cut, the handling machine has not yet been detected.
- the first diffusion sensor 23 is cut by the handling machine.
- the system records the triggering order of the sensors so that the loading of the unloading can be identified.
- FIG. 10 shows the detection of the handling device by the first reflection sensor 27.
- the handling device is detected by the first reflection sensor 27 cooperating with the reflector positioned on the handling device.
- FIG. 11 represents the taking of photos or films. Photos or films are taken only if the container support or container is present.
- the photo or film triggering unit allows photos or films to be taken if the second diffusion sensor 24 is cut or indicates the passage in front of terminal 20, then the second reflection sensor 28 is cut or indicates the presence of the container support or of the container, then the first diffusion sensor 23 is cut or indicates the presence in front of the terminal 20 and finally if the second reflection sensor 28 indicates the presence of the container or the container support.
- the principle of using four detection cells makes it possible to automatically detect whether it is a loading or unloading and the empty handling machine is never photographed or filmed.
- the system makes it possible to trigger an event during the precise passage of a container or a container support, for example during the loading or unloading of a truck.
- the system comprises depth sensors for measuring the volume. These sensors return a matrix of points each containing the distance between the sensor and the potential object.
- FIG. 12 makes it possible to see the measurement with a depth sensor located above a container support.
- This top view makes it possible to recover at least a distance in height from the container or from a container support.
- FIG. 13 makes it possible to see with a depth sensor located above at least one container and two others on the side in order to obtain an exhaustive measurement of the dimensions of the container or of the container support.
- the depth sensors being positioned on a gantry above the passage of a container or the container support. This system allows you to take a photo or film and measure the volume of the container or container support.
- a microcontroller allows using a measurement processing algorithm to reconstruct a three-dimensional view of the three measurements made of the container or of the container support and to extract the maximum external dimensions therefrom.
- Figures 14 and 15 show a three-dimensional view from two different angles. These figures show a point cloud representing the measurement made by the depth sensors. Help of the control unit, the volume is deduced from these measurements. The three dimensions height, width and length being taken from these depth measurements.
- the packets are not distinguished one by one, the calculation of the volume is not the result of the volume of each packet but an overall measurement.
