Description

Title of the invention: Parcel transport installation and vessel equipped with such an installation FIELD OF INVENTION

[0001] The present invention relates to a parcel transport installation, as well as to a ship equipped with such an installation. STATE OF THE ART

[0002] In a building, such as a ship, many packages are moved from a storage or production floor (also called a deck on a ship) to floors for use and / or temporary storage of these packages.

[0003] Such packages are, for example, packages of clean linen, luggage or consumables, such as drinks or food for a bar or restaurant.

[0004] These packages are transported using trolleys pushed by people. Thus, for horizontal journeys, transport is simply carried out by pushing the trolley. For vertical transport, it is carried out using service elevators not specifically designed for this task, which may also be a freight elevator or similar device.

[0005] Indeed, there may be a space constraint limiting the number of elevators, such as for example on a ship.

[0006] However, such transport generates disturbances at the level of the service elevators and requires a significant number of human handling operations.

[0007] Thus, the disturbances noted include the following: - Managing the processing and inventory of parcels is not easy, - Parcel flows are not easily traceable, - There is a risk of parcels, which contain items such as linens or consumables, being unavailable to people who need them. - The workspace is cluttered in areas where parcels are prepared, for example in a laundry room, - Parcel delivery times are significantly longer. - The flow of people and trolleys passing through the elevators and decks of the ship is significant, generating unproductive waiting times and requiring the mobilization of a large number of people to carry out the transports within a constrained timeframe; - there is an accumulation of parcel flows of different types at the same time, for example at the beginning and end of a cruise on a ship, and traffic peaks can overlap. - the upstream and downstream parcel flows are not separated, for example an upstream flow of clean laundry and a downstream flow of dirty laundry.

[0008] Thus, particularly on a ship, the transport of parcels is not very optimized due to numerous disturbances. Description of the invention

[0009] The present invention aims to overcome all or part of the drawbacks mentioned above.

[0010] In particular, the invention aims to provide a parcel transport system with optimized and highly automated flows, thereby limiting manual operations.

[0011] According to a first aspect, the invention proposes a parcel transport installation, remarkable in that it comprises: - an elevator shaft comprising a mobile elevator car between at least two floors, - a mobile parcel transport unit, the mobile unit comprising a removable chassis supporting a mobile parcel loading / unloading conveyor, the installation being such that: - the elevator car is configured to receive the mobile unit, - at least two floors each include a first access to the elevator car, of which at least one loading floor has a parcel loading conveyor onto the mobile unit and at least one receiving floor has a parcel receiving conveyor from the mobile unit, each first access being configured to allow the transfer of parcels either from the loading conveyor to the mobile conveyor or from the mobile conveyor to the receiving conveyor, and - the mobile unit is mobile between a rest position outside the elevator car and a use position inside the elevator car, the transfer from the use position to the rest position and vice versa being carried out by passing the mobile unit through the first access.

[0012] Thus, thanks to the invention, the number of people employed in parcel transport is reduced and the management of parcels and their flow is improved. More generally, parcel transport is optimized.

[0013] The installation according to the invention is advantageously and optionally supplemented by the following features, taken alone or in any of their technically possible combinations:

[0014] - Each floor includes a second access to the elevator cabin, the second access being configured to allow access to the elevator car for at least one person in order to allow their transfer from one floor to another. Thus, the invention allows, with the same installation, the transport of people and the transport of parcels in a manual or automated manner.

[0015] - Each conveyor is a roller conveyor, preferably a roller conveyor motorized. Thus, each conveyor is made in a simple and reliable manner. By "each conveyor," we mean in particular each conveyor in the conveyor system formed by the mobile conveyor, each loading conveyor, and each receiving conveyor.

[0016] - Each conveyor is multi-level, preferably between four and eight levels. This optimizes package transport, particularly because the number of packages that can be transported by the mobile conveyor is increased despite the limited space in the elevator car. More generally, the use of multi-level conveyors reduces the space occupied by these conveyors for the same number of packages stored or to be transported.

[0017] - Each conveyor is configured to receive packages.

[0018] - All conveyors have the same number of levels. Thus, the management of parcels and their flow is further optimized.

[0019] - At least one floor includes a storage area for the mobile unit In the resting position, the storage area is directly adjacent to the elevator shaft. Thus, the storage of the mobile unit is carried out simply and quickly.

[0020] - The storage area is located between the elevator shaft and the conveyor of The receiving or storage area is located between the elevator shaft and the loading conveyor. Therefore, the mobile unit's conveyor can also be used for parcel storage during parcel distribution or parcel preparation.

[0021] - Alternatively, the storage area is located on a floor without receiving conveyor and no loading conveyor. Thus, the storage area is isolated.

[0022] - The storage area is an airlock configured to delay the propagation of a Fire can spread from the elevator shaft to the floor containing the storage area, or vice versa. This provides better isolation for the storage area.

[0023] - The installation includes an operating unit and parcel detectors Configured to count the packages on each conveyor, the operating unit is configured to control, based on the number of packages counted by the package detectors, both the transfer of the mobile unit from its operating position to its resting position and vice versa, the quantity of packages loaded onto the mobile conveyor by the loading conveyor, and the quantity of packages unloaded from the mobile conveyor onto the receiving conveyor. This optimizes package management and flow.

[0024] - Each package has an identifier configured to be detected by the Package detectors. Thus, package detection is simplified, and the management of packages and their flow is further optimized.

[0025] - The operating unit is configured to control according to the number of Packages are counted by package detectors based on data contained in each package's identifier and detected by the detectors. This data relates to the nature of the respective package, including the transfer of the mobile unit from its operating position to its resting position and vice versa, the quantity of packages loaded onto the mobile conveyor by the loading conveyor, and the quantity of packages unloaded from the mobile conveyor onto the receiving conveyor. This process further optimizes package management and flow.

[0026] - The mobile unit includes a transfer mechanism configured to perform the The transfer mechanism allows for the movement from the operating position to the resting position and vice versa. Thus, the transfer from one position to the other is achieved simply. By "and vice versa," it should be understood that the transfer mechanism is also configured to perform the transfer from the resting position to the operating position.

[0027] - The transfer mechanism includes a motor mechanism configured to perform The unit automatically transfers from the operating position to the resting position and vice versa. This makes the transfer from one position to another simple and automated, and eliminates the need for manual handling of the mobile unit.

[0028] - The elevator car includes a presence detection device, the unit The operating system is configured to prevent the elevator from moving from its resting position to its operating position as long as the presence detection device detects a person in the elevator car. This improves the safety of the installation.

[0029] - The first access point includes an automatic door. Thus, the handling of packages and Their flow is further optimized.

[0030] - The second access includes an automatic door. Thus, the transport of people The space in the elevator is also optimized.

[0031] - Each automatic door is an automatically opening and closing door automatic. Thus, the usage time of the elevator cabin is optimized.

[0032] - The operating unit is configured to control the movement of the cabin at least one elevator when the mobile unit is in its operating position. This further optimizes the management of packages and their flow.

[0033] - The loading stage is lower than the receiving stage. This arrangement is particularly advantageous especially on a ship, in which the deck dedicated to parcel preparation is generally lower than the deck for parcel distribution.

[0034] - The elevator shaft comprises at least three floors, preferably at least six floors.

[0035] - Each package is a package of clean linen or a package of consumables, of preferably a package of clean laundry.

[0036] - The identifier is an RFID chip. Thus, identification is carried out remotely and this in a particularly simple and quick way.

[0037] - When the mobile unit is in the elevator car, each second access is closed. Thus, the safety of the installation is improved. Indeed, it is guaranteed that no person can access the elevator car when it contains the mobile unit.

[0038] - When a person is in the elevator car, each first access is closed. Thus, the safety of the installation is improved. Indeed, it is guaranteed that the mobile unit cannot access the elevator car when it contains a person.

[0039] According to a second aspect, the invention also proposes a vessel comprising an installation such as previously described.

[0040] Thus, in a ship with limited internal space, the use of such an installation is particularly advantageous.

[0041] The vessel according to the invention is advantageously and optionally supplemented by the following features, taken alone or in any of their technically possible combinations:

[0042] - The ship has at least two decks, preferably at least three decks, plus preferably at least six stories.

[0043] - The ship is a cruise ship. Such a cruise ship is configured for the Passenger transport, and is notably distinct from a cargo ship which is configured for the transport of goods. Thus, given that a large number of packages must be moved between decks within a cruise ship, where a large number of people also need to move between decks, the presence of such a facility is particularly suitable.
