Description
ROBOTIC MACHINE FOR REMOVING AND INSERTING TROMMEL SCREENS, AND
OPERATING METHOD THEREOF
Field The present invention relates to the removal and replacement of wear elements, such as "screens or panels" used in the separation process performed by the trommel.
The invention relates to a robotic machine for removing and inserting trommel screens or panels. Furthermore, the invention contemplates the associated method.
Background In the grinding process of different concentrating plants using SAG mills, at the exit from the mill a screening based on size is required, and this function is performed by a trommel, which is an equipment that rotates integrally with the SAG mill and the inner surface of said trommel is covered with sorting screens or panels which have slots. Due to the impact of the mineral on the screens, these are subjected to constant wear, for which reason they must be changed continuously.
Screens or panels are changed in a completely manual manner and must be coordinated with the overall maintenance of the mill, which generates a series of interferences that make it impossible to change all the panels during the mill maintenance period.
Furthermore, the very small work area makes it impossible to perform tasks in parallel.
Among the activities interfering with the panel changing process, the following can be mentioned:
= Changing the sieve: The crane passes over the trommel with the sieve, which means stopping work and clearing the area.
= Maintenance of water injection pipes: The two pipes

Due to the impact of the mineral on the screens, these are subjected to constant wear, for which reason they must be changed continuously.
Screens or panels are changed in a completely manual manner and must be coordinated with the overall maintenance of the mill, which generates a series of interferences that make it impossible to change all the panels during the mill maintenance period.
Furthermore, the very small work area makes it impossible to perform tasks in parallel.
Among the activities interfering with the panel changing process, the following can be mentioned:
= Changing the sieve: The crane passes over the trommel with the sieve, which means stopping work and clearing the area.
= Maintenance of water injection pipes: The two pipes
2 are removed and taken to a point where they are cleaned. Their center of mass is at a point inside the trommel that makes the passage of slings difficult.
= SAG maintenance requires constant rotations of the SAG-trammel assembly, which involves a system lockout-tagout (LOTO) process, reducing effective work times. Trommel works must be adapted to the mill works.
The activity of changing panels requires a series of preliminary jobs, such as:
= Removing shell = Cleaning the interior = Installing of scaffolds = Installing life safety rope = Determining the panels to be changed = Stocking new panels After performing the preliminary activities, removal of the panels commences, which is carried out using two crowbars with a heel inserted between panels on one side and hit with a mallet to assure reaching the lower part thereof. Then the crowbars are lowered at the same time until the panel is completely separated from the fixing rod or rail. At that point, the maintenance operators grab the panel from the sides and by means of horizontal movements, detach the edge of the panel from the missing rod. Slings are attached to the panel and the trommel is removed to the surface of the mill.
New panels are installed following the process opposite that for removal, adding the application of the impact with the mallet for introducing the panel into the fixing rail. This action is very dangerous for maintenance operators because the rebound of the mallet when it impacts the rubber in the panel requires enormous skill and care in order to not be hit.

3 Drawbacks of the current process include Production: the current process does not allow complete replacement of the panels, which entails a risk when leaving worn panels that may potentially fail during the next operating period. There is a risk that production will be stopped to change a panel that breaks.
Occupational health and safety:
o The current process involves getting into the trommel, which is intrinsically dangerous, working at a height and material falling from the trommel, among others.
o Maintenance operators must handle the panels, which entails a high physical demand and risks of being hit or trapped when removing and inserting panels.
The state of the art comprises national application 3496-2012, which relates to a pick-up and release system comprising a pick-up mechanism comprising a robotic arm, a pick-up device assembled in a rotational manner on the robotic arm, a movable insertion device. Said application furthermore discloses a method for grabbing and releasing an object with a pick-up system. This application does not disclose a method involving a robotic arm for removing and inserting trommel screens or panels.
In addition, national application 2642-2005 discloses a robotic method for the process of removing bolts from SAG mills, which in turn comprises providing a robotic arm with at least 5 degrees of freedom, grabbing a nut cutting tool from a tool carrier rack, cutting or releasing the nut and grabbing a tool for removing bolts and knocking a securing bolt out of the mill.
Application 2642-2005 discloses a process for removing bolts but it does not disclose a method for removing and inserting trommel screens or panels.

4 There are not documents in the state of the art referring to a method for removing and inserting trommel screens or panels;
therefore, there is a need to provide a method that allows automating the operation for changing panels, removing people from this operation and reducing times for this activity.
The invention reduces the times for changing a panel, which in turn allows being able to replace most or all of the panels during maintenance, being adapted to the available time or times without affecting the rest of the critical maintenance jobs.
Reliability of trommel operation therefore improves given that the risk of emergency stops for replacing broken panels decreases.
Based on the foregoing, the objective of the present invention is to develop a method and robotic device capable of performing the process of removing and inserting panels in a stand-alone, rapid and safe manner.
Summary The present invention relates to a robotic machine and to a method for removing and inserting trommel screens or panels. The robotic machine contemplates three main parts: a tool for grabbing the panel with damping system (1), a robotic arm (2) with 6 degrees of freedom which manipulates the tool and allows the panel to be removed and replaced, and a mobile main beam (3) which is anchored to the structure of the building or site of installation or assembly and allows moving the robotic manipulator and introducing it into the trommel to carry out the operation.

The tool (1) for grabbing the panel (19) consists of a chassis structure (9), four damping systems (6), four pneumatic drives (5) and four pairs of fingers (4). The fingers are introduced into the slots (21) of the panel (19) between the metal inserts (20) it has and allow securely grabbing it. The
6 pneumatic drives (5) on which the pairs of fingers are assembled allow the fingers to open and close for grabbing and leaving the panels according to the operating logic. The damping system (6) is a unit made up of springs (7) and a linear guiding system (8) on which the pneumatic drive is assembled and the function of which is to gradually transmit the reaction force of the panel to the robotic arm, such that it prevents impulsive loads therein which can generate excessive torques. The chassis structure (9) on which the damping system is assembled offers strength to the tool. Furthermore, it has a flange coupling (10) which allows attaching the chassis of the tool to the robotic arm.
The robotic arm (2) for grabbing and manipulating the tool consists of a torque sensor (11), a wrist (12), two oscillating arms (13) and a rotating column (14). The torque sensor is placed against the wrist (12) of the robotic arm and allows the robotic arm "to feel" the force it applies and depending on said force, changes trajectories. The wrist (12) allows turning and orienting the tool depending on the point for grabbing the panel. The oscillating arms (13) allow moving the tool to the different trommel work points. The rotating column (14), which is the base of the entire robotic arm, allows rotating the entire robotic arm to reach different positions.
The mobile main beam (3) consists of a crossbeam (15), a support structure (17), a drive system (16) and a mobile carriage (18). The robotic arm is assembled on the crossbeam (15) and said main beam moves, allowing the robotic arm to enter and exit the trommel. The drive system (16) moves the crossbeam. The support structure (17) on which the crossbeam and the drive system are assembled allows the entire unit to be anchored to the structure of the building or site of assembly. The mobile carriage (18) moving on the crossbeam has two compartments where on one hand the robotic arm places the removed panels, and on the other hand

The mobile carriage (18) moving on the crossbeam has two compartments where on one hand the robotic arm places the removed panels, and on the other hand
7 loads the new panels; this carriage allows moving the panels away from and into the trommel.
The control and operating unit of the robotic machine corresponds to a group of cabinets which are located on the main beam, which have the function of providing power and control to the robotic machine, in addition to having controls for commanding and monitoring same. The cabinets forming the robotic machine are: the switchgear or SG, the control panel or CP and the human machine interface or HMI, which are described below:
SG: Corresponds to the cabinet containing the protective elements against overvoltages, protections for electrical equipment in the control cabinet, local control cabinet of the robotic arm and equipment like the same robotic arm and HMI
operator panel. Also, the single-pole busbar for electrical distribution to the different elements and cabinets is also located here. It has a main single-phase thermomagnetic breaker for opening or closing the electric power intake circuit, in addition to luminous pilot light indicators.

Additionally, the present invention has a safety architecture that is formed by a controller monitoring all the safety signals of the robotic machine, emergency stops and excessive torques of the robotic machine. The emergency stops are
8 mushroom-type stop buttons and are located in the operating panel and to the side of accesses and windows. The actuation of emergency stops causes the robotic machine to shut down.
Restoration from an emergency stop alone does not leave the machine in conditions for starting up again; recognition of the emergency stop by the operator is required. The emergency stops are reset in the area where the emergency stop was activated, but recognition of the emergency stops is done through the operating display.
The robotic machine is operated by means of an operating console located in a secure site in the mobile main beam (3); the robotic machine for removing and inserting panels is controlled and configured in this operating console. The machine is switched on and the crossbeam (15) moves into the trommel, for which purpose it depends on the viewing or inspection cameras, which help it to remotely position itself. Then the mobile carriage is loaded with the panels that will be assembled and the carriage moves on the crossbeam into the trommel on the side of the robotic arm. After the robotic arm of the robotic machine is positioned in the line of action of the panels to be replaced and depending on the information provided by the operator, the robotic arm moves towards the panel (19) to be removed, the pairs of fingers (4) are actuated and the panel is grabbed. The robotic arm pulls the panel (19), making it rotate around one of the anchoring rods, completely releasing a first side, to then continue with the other side, thereby completely letting go of the panel. Once the panel is released from the trommel, by means of the robotic arm the robotic machine moves the panel to the mobile carriage (18) and leaves it in the compartment for used panels, and the robotic arm immediately grabs a new panel from the other compartment of the same mobile carriage (18) and performs the reverse sequence for inserting the new panel in the
