Definitions

  • the present invention relates to a package collection device for collecting packages through one or more retractable hollow columns provided with package inlets.
  • Said hollow column can be partially extracted above ground level or completely concealed below ground level by means of an actuator device, with an upper surface of the hollow column being flush with the ground level providing a support plane.
  • Said hollow column is connected, below ground level, with an upper end of a storage conduit which is in connection with a duct system in charge of channeling and conveying said packages by means of an airstream generated by suction from a collection center.
  • the packages will be waste products, but the conveyance of another type of packages is also contemplated.
  • Package collection devices for collecting packages through at least one column including a pit located below ground level are known, for example, through documents US2528056A , US3800973 , ES2209690T3 , DE102004001336A1 , and DE19837453A1 .
  • US10399799B2 discloses a device in accordance with the preamble of claim 1.
  • the present invention relates to a collection device for collecting packages through at least one retractable hollow column.
  • the packages are introduced by a user into the package collection device through said at least one hollow column.
  • the collection device may therefore consist of several hollow columns, for example, intended for collecting different types of packages.
  • the packages are waste products, for example different fractions of waste products separated according to their type, containers, paper, glass, etc., to facilitate recycling.
  • the proposed invention comprises, in a manner that is known per se, the following components:
  • Ground level shall be understood to be a plane, that is horizontal or has a slight deviation of at most 15o, for example, with respect to the horizontal, which users in charge of depositing packages in the hollow column can pass through.
  • the components of the device located below ground level mainly the storage conduit, may be buried, if the ground level coincides with the soil level, for example contained inside an underground pit. Alternatively, when the ground level from which the hollow columns emerge is located in a building with several superimposed levels, the components located below ground level will be located in a lower level of said building.
  • Said storage conduit amasses the packages deposited by the users through said at least one package inlet until the emptying thereof through the pneumatic package collection duct system is determined, at which time the hatch located in the lower end of the storage conduit opens while a pneumatic suction of the packages through said pneumatic package collection duct system occurs at the same time.
  • these pneumatic package collection duct systems consist of a network of ducts connecting a plurality of collection points with a collection center.
  • a suctioning unit suctions air from the inside of said network of ducts having air inlets, normally in the collection points, generating an airstream that goes from the collection points to the collection center, entraining the packages deposited in the collection points to the center where they are stored and usually compacted for subsequent conveyance and processing.
  • the proposed collection device for collecting packages would constitute one of said collection points.
  • Each collection device for collecting packages may consist of one or more hollow columns and/or of several storage conduits, the package inlets of a hollow column being connected to one and the same storage conduit or to different storage conduits.
  • a collection device to include, for example, several hollow columns, each with one or more package inlets, each hollow column being connected to a different storage conduit.
  • the collection device includes several package inlets in one and the same hollow column, each of said package inlets being connected to a different storage conduit.
  • the present invention furthermore proposes, in a manner that is not known in the state of the art per se, the following features:
  • the actuator device allows moving the hollow column or columns in a guided manner between the retracted position and the extracted position, these hollow columns therefore being retractable.
  • said guided movement of the hollow column will be a rectilinear, preferably vertical, movement.
  • the hollow column will be guided, for example, by means of guides located below ground level and parallel to the path of movement, to which there will be attached in a sliding manner a lower portion of the hollow column, located below ground level in both the extended position and the retracted position and below the upper portion.
  • the actuator device will be in charge of actuating the movement of the hollow column between the extracted and retracted positions.
  • the actuator device may consist, for example, of pneumatic pistons, hydraulic pistons, or linear motors or other configurations such as a rack-and-pinion configuration.
  • the upper portion of the hollow column which emerges above the plane of the ground in the extended position but is concealed below said ground level in the retracted position, comprises one or more package inlets which, with the hollow column being in the extracted position, will be accessible to a user passing through the ground level.
  • An upper end of the upper portion of the hollow column is preferably flat and parallel to the plane of the ground. In the retracted position, said upper end will be flush with the ground level, allowing a user to pass above the hollow column without any obstacle.
  • An inner conduit of the hollow column communicates the package inlet with a lower aperture of the hollow column located in the lower portion, such that any package introduced into the hollow column through a package inlet falls through the inner conduit due to the effect of gravity, exiting the hollow column through said lower aperture.
  • the upper end of the storage conduit is located below ground level and vertically aligned with the hollow column.
  • Said upper end will preferably be a static upper end, i.e., it will not move together with the vertical column, so its position is fixed regardless of the position of the hollow column.
  • said upper end may serve as an air inlet when the suctioning unit generates suction in the conduit connected to said storage conduit, entraining packages located inside said storage conduit or even around the upper end.
  • Said upper end and a portion of the hollow column which will include at least a part of said lower portion adjacent to the lower aperture of the hollow column, are inserted snugly one into the other at least when the hollow column is in the retracted position, forming together a telescopic segment.
  • the hollow column if the hollow column has a cross-section with a size larger than the upper end of the storage conduit, the hollow column will be arranged around said upper end when the hollow column is in the retracted position, said upper end being contained inside the hollow column, preferably concentric to one another.
  • the upper end is also proposed for the upper end to be able to include a flared opening fitted into the hollow column.
  • the upper end of the storage conduit has a cross-section with a size larger than the hollow column, then the upper end will be arranged around the hollow column when the hollow column is in the retracted position, said hollow column being contained inside the upper end.
  • any of these two alternatives allow a compact construction that requires very little space below ground level, since the storage conduit and the hollow column partially overlap in length in the retracted position, constituting a telescopic segment. This allows the package storage conduit to also partially overlap with the hollow column in the retracted position, efficiently maximizing the storage capacity below ground level.
  • the installation of a sealing system or a hermetic joint between the hollow column and the storage conduit is not considered necessary; however, said possibility is not ruled out to prevent the packages from being interposed between both elements.
  • the hollow column may include air inlets to allow an airstream to be produced through the storage conduit from the hollow column during the emptying of the storage conduit. Said air inlets may be arranged to allow the entry of air with the hollow column being in the retracted position.
  • said air inlets will be arranged at the upper end of the hollow column.
  • they will be arranged in side walls of the hollow column and/or air inlets will be included in the ground level to allow the entry of air from above the ground level to a casing, space, or pit located below ground level containing the collection device.
  • Said air inlets of the ground level can be, for example, a gap between the hollow column and the hole from which said hollow column emerges, or grills arranged around same.
  • said upper end of the storage conduit is connected to a portion of the hollow column by means of an extensible connector conduit, i.e., a conduit the length of which can be modified as it is flexible or elastic, for example, a compressible or corrugated conduit of variable length or a textile tube. Therefore, the connection will be maintained regardless of the position of the hollow column, since the extensible connector conduit will expand or shrink to adapt to the movement of the hollow column.
  • said extensible connector conduit will be interposed between and connected to the upper end of the storage conduit and the hollow column.
  • the storage conduit With the upper end of the storage conduit being arranged below and vertically aligned with the hollow column in the extracted position and connected to a portion of the hollow column by means of a snug insertion and/or by means of an extensible connector conduit, it is assured that the packages introduced through the package inlets will fall into the storage conduit through the upper end by gravity, being stored in said storage conduit until the emptying thereof.
  • the storage space defined inside the storage conduit, can occupy from the lower end to the upper end of the storage conduit. Therefore, part of said storage space may be contained inside a portion of the hollow column at least when said hollow column is in the retracted position, given that said portion of the hollow column and the upper end are inserted one into the other, thereby maximizing the storage space.
  • the package storage space can also occupy at least part of said extensible connector conduit when the hollow column is in the extended position.
  • the length of the extensible connector conduit would be reduced, but this is not true for the package storage space which would then occupy a larger portion of the extensible connector conduit or the entire length thereof and part of the hollow column in the retracted position.
  • the collection device prefferably be able to include a pit located below ground level.
  • the storage conduit will be located inside said pit and also the hollow column in the retracted position. Therefore, a compact solution like the one proposed allows reducing the size of said pit, reducing the technical requirements for its installation and its cost.
  • the storage conduit itself or a casing enveloping it contains all the components of the collection device that must be located below ground level, allowing said storage conduit or said casing to be buried directly in the ground, reducing operations and installation costs.
  • the upper end of the storage conduit and the lower portion of the hollow column are at least partially inserted one into the other also when the hollow column is in the extracted position.
  • part of the upper portion of the hollow column and the upper end of the storage conduit may also be inserted one into the other in the retracted position.
  • the hollow column and the storage conduit are not inserted one into the other only in the retracted position, but they are also partially inserted one into the other in the extracted position.
  • the upper end of the storage conduit and the hollow column will always be inserted one into the other in both the extracted position and the retracted position, thereby assuring that there is always a continuity between the inner conduit of the hollow column and the storage conduit.
  • the hollow column and the storage conduit not to be inserted one into the other in the extracted position, said insertion being caused only when the hollow column is moved to the retracted position.
  • the hollow column being in the extracted position, there will be no continuity between the inner conduit of the hollow column and the storage conduit, although since they are vertically aligned, the packages would go from the inner conduit to the storage conduit by gravity without problem.
  • This option facilitates the entry of air from the pit into the storage conduit, as well as the cleaning, inspection, and maintenance tasks.
  • the storage conduit may furthermore include a fill sensor of the storage space for determining its fill level, said fill sensor being connected to the hatch of the lower end of the storage conduit.
  • the packages would protrude above the upper end of the storage conduit or be arranged in an area intended for containing the hollow column in the retracted position, making the placement of the hollow column in the retracted position difficult or preventing same.
  • the existence of said fill sensor is important, allowing detecting when the fill level of the storage conduit is close to maximum so as to proceed to empty same by means of activating the suctioning unit and opening the hatch.
  • the fill sensor may consist, for example, of an optical detector such as a distance meter used for measuring descending vertical distances and oriented towards the inside of the storage conduit, or a light beam transverse to the storage conduit which detects a specific fill level by means of the interruption thereof.
  • optical detector such as a distance meter used for measuring descending vertical distances and oriented towards the inside of the storage conduit, or a light beam transverse to the storage conduit which detects a specific fill level by means of the interruption thereof.
  • Other types of sensors such as sonic or radiofrequency sensors, are also contemplated.
  • the storage conduit may include a curved or non-vertical portion inserted into the hollow column when it is in the retracted position.
  • the storage conduit is essentially vertical, and the pneumatic package collection duct system consists of essentially horizontal ducts.
  • the lower end of the storage conduit preferably has a curvature for a smoother transition between the vertical direction and the horizontal direction. The inclusion of this curved segment or part thereof inside the hollow column in the retracted position allows obtaining a more compact configuration of the collection device, and therefore lower installation costs.
  • the hollow column may furthermore contain and support a press device provided with a press surface that can be vertically inserted into the storage conduit through the upper end, said press surface being movable between a standby position, in which it is not interposed between said at least one package inlet and the storage conduit, and a pressing position, in which it is at least partially interposed between said at least one package inlet and the storage conduit.
  • a press device provided with a press surface that can be vertically inserted into the storage conduit through the upper end, said press surface being movable between a standby position, in which it is not interposed between said at least one package inlet and the storage conduit, and a pressing position, in which it is at least partially interposed between said at least one package inlet and the storage conduit.
  • the pressing surface will move vertically, either together with the movement of the hollow column between the extracted and retracted positions, or by means of actuation by the press device, causing the packages contained inside the storage space to be pressed.
  • the press device when the press device is in the standby position, it is not interposed between the package inlet and the storage conduit, but when it is in pressing position, said press device is at least partially inserted into the storage conduit at least when the hollow column is in the retracted position.
  • the press device not to interfere with package collection, but when the hollow column is in the retracted position, said press device can be in the pressing position, being inserted at least partially into the storage conduit, compressing the packages housed therein.
  • the press device can move from the pressing position before, during, or after the movement of the hollow column from the extracted position to the retracted position, allowing the press device to be located in the pressing position, for example, and then proceeding with the movement of the hollow column, thereby causing the partial insertion of the press device into the storage conduit through its upper end and the compaction of the packages accumulated therein, thus allowing more packages to be stored before proceeding to perform emptying by suction.
  • This arrangement of the press device is applicable in both the embodiment according to which the storage conduit is housed inside the hollow column when it is in the retracted position, and the embodiment according to which the hollow column is the one that is partially inserted into the storage conduit when it is in the retracted position, also being compatible with the use of the extensible connector conduit.

  • said pressing surface will be operated by means of an actuator mechanism, which may include an electric, hydraulic, or pneumatic motor, a scissor mechanism, a rack-and-pinion mechanism, or others.
  • an actuator mechanism which may include an electric, hydraulic, or pneumatic motor, a scissor mechanism, a rack-and-pinion mechanism, or others.

  • the packages may include a radiofrequency label which, when detected by the actuation signal generator 32, will trigger the generation of an actuation signal to actuate the movement of one or more hollow columns 20.
  • the actuation signal generator 32 will be a biometrics sensor, such as a fingerprint sensor or a facial recognition camera, which allows identifying the users with access rights, triggering the movement of the hollow columns 20.
  • cover 23 of the hollow columns 20 or the lid 11 of the pit prefferably includes an air inlet, facilitating the suction of the packages contained in the storage conduit 40.
  • Said air inlet may be an air inlet that may consist of a gap or of a grill between the lid 11 and the hollow column 20.
