Definitions
- the invention concerns an automated machine to perform fruit growing work according to the preamble of claim 1.
- Document WO2018/057562A1 shows a known machine for carrying out fruit growing work activities presenting the characteristics of the preamble of claim 1. It comprises:
- a platform equipped with means to move on the ground;
- a supporting structure arranged on the platform
- support means for supporting the support bodies on the supporting structure
- a plurality of arms each of which is supported with a proximal end thereof on a support body; . a plurality of work devices suitable for carrying out fruit growing work , each of which is connected to a distal end of an arm;
- connecting means for connecting the working devices to the distal ends of the arms
- a plurality of cameras which acquire images of the area in which the fruit growing work must be carried out
- a command and data processing unit which controls the operation of the machine and its components on the basis of the images acquired by the cameras.
- each support body is supported on the supporting structure in a rotatable way around at least one rotation axis, in particular two rotation axes, and supports several arms. These arms are arranged in a distributed manner on the respective support body and each of them is made of two parts mutually hinged. Furthermore, each working device is positioned at the distal ends of at least two arms, i.e. it connects to each other at least two of the arms which are supported on a support body.
- the machine is therefore organized in groups of working devices and each group of working devices is associated with the arms which are supported on a respective support body.
- the rotations of the support body involve a group rotation, i.e. all together, of the arms and therefore also of the working devices which are located at the distal ends of them.
- a group rotation i.e. all together
- the working devices which are located at the distal ends of them.
- there is a movement along a direction that is parallel to the direction of advancement of the machine, to associate each work device with its own work area, and / or a movement along a direction that is instead perpendicular to the direction of advancement. to approach the plants or move away from them the work devices.
- each working device Due to the extension or retraction movements of those arms at the ends of which the same working device is positioned, on the other hand, an additional movement towards the plants or away from them can take place, i.e. each working device can be moved further individually.
- the task underlying the present invention therefore consists in developing and making available an automated machine for carrying out fruit growing work which has been improved in its ability to carry out fruit growing work, due to the fact that it is always possible and easy to position individually in an optimal way each of its working devices.
- this task is solved if an automated machine for carrying out fruit growing works presenting the characteristics indicated in the preamble of claim 1 additionally also has the characteristics indicated in the distinctive part of claim 1.
- the support means support each support body in a singularly translatable way along a respective part of the load-bearing structure and that there are displacement means, which act individually on each support body to translate it along said respective part of the load-bearing structure .
- the arms are orientable arms, each of which is supported on a respective support body and can be rotated around a respective first axis of rotation, and that rotation means are also part of the machine. , which act individually on each pivoting arm to make it rotate around the respective first axis of rotation.
- each work device corresponds to a single rotatable arm and to each rotatable arm corresponds to a single support body.
- the movements that are carried out by a support body therefore involve a corresponding movement of only the swivel arm which is supported on the moving support body, while the other swivel arms, which are supported on other support bodies, are not involved in any way from these movements.
- the possible rotations of the orientable arm caused by the rotation means then allow to move the working device with respect to the support body and contribute, together with the movement of the support body, to the optimal positioning of the working device.
- each working device can be brought into its optimal working position independently of the positioning of the other working devices, i.e. without the positioning of a working device affecting the positioning of any other working device.
- the machine approaches the orchards that must be subjected to the work: it is basically a movement along the direction of advancement of the machine.
- the command and data processing unit chooses, on the basis of the images transmitted by the cameras, the most suitable support body to bring a work device to the optimal position to perform the intended work and commands the displacement means, so that the selected support body is translated along a respective part of the supporting structure.
- This respective part of the supporting structure appropriately extends obliquely upwards, or better still vertically, so that following this translation, a height positioning of the support body and also of the swivel arm that is supported on it takes place.
- the work device located at the distal end of this swivel arm is positioned in an optimal way and which, due to the effect of the previous movements, has already been brought close to the work area (along the direction of advancement of the machine) and at the right height from the ground (along a part of the supporting structure).
