Definitions

  • the present invention as expressed in the statement of this specification refers to a tool for cutting and extracting samples of various kinds.
  • the main field of application of the present invention is biology since the cutting and extraction tool of the present application for the extraction of plant leaf samples has preferably been designed without implying having to tear the plant leaf.
  • the drive of the cutting element available to the tool may be automatic or manual while the operation of the extraction means will always be automatic.
  • the present invention allows the positioning of the tool manually or automatically as it comprises means for its installation in the articulated arm of a robot.
  • the procedure for extracting samples of plant leaves with the manual perforator is as follows: once the sheet from which the sample is to be extracted is selected, a rigid and flat support is placed under the sheet. With a circular movement, the blade is pressed with the perforator against the support and the sample is cut. Often the sample is stuck inside the piercing tube so it must be removed. This can be done by blowing air through one end of the perforator or by inserting a rod.
  • the invention consists of a tool for cutting and extracting samples of diverse nature, which preferably comprises the extraction of plant samples.
  • the main object of the present invention is the tool, which will preferably be automatic, for cutting and extracting samples.
  • the tool comprises having a recess in the lower part for the placement of a material from which the sample is to be extracted. This material may be of a different nature although it will preferably be a material of plant origin and more preferably they will be plant leaves.
  • the tool comprises having a metal plate located on the underside of the recess, said plate and the underside of the recess comprising a central and through hole. It also includes means for driving a cutting tool that will be responsible for cutting the sample.
  • the tool is characterized in that it at least comprises: o a cylindrical rod connected at its upper end to the actuation means and which at its free end comprises a widening that defines a push head and ejection of the sample.
  • the rod is disposed inside a cylindrical tubular body; Y,
  • Said tubular body comprises a cutting element at its lower end, a recess in the upper part for fixing a spring and some mechanical stops in the lower part of the upper recess and in the upper part of the cutting tool so that when the drive means push the cutting element down to perform the cutting the mechanical stops stop against the upper edge of the vertical sliding guide means and against the metal plate and brake the cutting element.
  • the drive means of the cutting tool at least comprise:
  • the tool comprises gripping means for manually positioning the tool.
  • the tool comprises means for coupling the tool to a robot.
  • These coupling means will be more preferably located at the top of the guiding means to perform an automatic positioning of the tool.
  • the cutting element comprises being cylindrical.
  • the motor comprises being a servomotor.
  • the cylindrical tubular body comprises a recess at its lower end to accommodate the thrust and ejection head of the sample.
  • the cutting and ejection tool comprises a collection element of the sample extracted at the bottom of the tool so that when the sample is ejected, it falls to the collection element.
  • the motor comprises being inside a sealed case having at least two holes.
  • the first hole made for the output of the motor power and control cables and a second hole made for the output of the motor shaft.
  • Both holes comprise conventional sealing means such as a cable gland for the hole through which the cables are removed and a shaft seal for the hole through which the motor shaft leaves.
  • Another object of the present invention is the use of the tool, which will preferably be automatic, for cutting and expelling samples, these samples being of different nature.
  • Another object of the present invention is the use of the tool, which will preferably be automatic, for cutting and expelling samples for cutting and extracting plant samples.
  • Another object of the present invention is the use of the sample cutting and ejection tool for cutting silicone discs that can be used among other things as caps in test tubes.
  • Figure 1. Shows a perspective view of a particular embodiment of the sample cutting and extraction tool object of the present invention.
  • Figure 2A Shows a side view of the embodiment of Figure 1.
  • Figure 2B. Shows a rear view of the embodiment of Figure 1.
  • Figure 2C- Shows a plan view of the embodiment of Figure 1.
  • Figure 3. Shows a view of the longitudinal section of the embodiment of Figure 1, along its central axis with the cutting element located in the starting position.
  • Figure 4.- Shows a view of the longitudinal section of the embodiment of Figure 1, along its central axis with the cutting element in the starting position of the sample cut.
  • Figure 5. Shows a view of the longitudinal section of the embodiment of Figure 1, along its central axis with the cutting element in the end position of the sample cutting and the rod having already pushed the sample out of the cutting element .
  • Figure 1 shows an embodiment of the tool, which in this case is automatic, for cutting and extracting samples (1) comprising a perpendicular axis (4) that moves in the cutting direction by means of a conventional piston-rod mechanism - crank operated by a motor (7).
  • This axis has guide means (16) at its ends and travels along two guides (17).
  • the motor can be of any type although it will preferably be a servomotor, it rotates its axis which in turn makes the steering wheel (6) rotate.
  • the turning movement of the flywheel (6) is transmitted to a connecting rod (5) that moves the shaft (4) up and down.
  • the elements selected in this embodiment, flywheel (6), connecting rod (5) and shaft (4) could be changed by any other that transformed the movement rotating the motor (7) in a displacement movement as described above.
  • a spring (8) placed between the two cylinders (9,10) of the cutting tool allows the cut-eject sequence to be carried out with half a turn of the flywheel (6).
  • the cylindrical tubular body (9) is pushed down, integral with the spring (8) and the cylindrical rod (10), and cuts the target sheet to obtain the sample.
  • the cylindrical tubular body (9) can no longer advance because mechanical stops (11) located in the upper and lower part of the cylindrical tubular body (9) bump against the guiding means (12) of the body itself and against the area (13) closest to the hole of the metal plate (3) located in the lower part of the recess respectively, causing the force exerted by the piston-crank-crank mechanism to exceed the elastic force of the spring (8) and thus the cylindrical rod (10) can descend until the cut sample is ejected out of the cutting tool.
  • Figures 3 to 5 show the process of cutting and expelling the sample in 3 phases. It is clearly shown how when the forward movement of the cylindrical tubular body (9) is stopped, the cylindrical rod (10) continues to advance so that the thrust head (15) of said rod (10) pushes the sample that would have been trapped inside the cutting element (2).
  • the perforated metal plate (3) has a small set so that the cutting tool centers it and does not collide with it or get stuck.
  • a servo motor that is programmable has been used, so that both the speed and the force and the path of the tool can be controlled and parameterized depending on the type of sheet to be extracted.
  • the tool has the coupling means (14) for mounting on the element Barrett WAM robotic arm terminal to control its position and orientation in space.
  • This arm allows both operator-assisted guidance to execute a controlled cut, as well as complete automation of the tool positioning and cutting process.
  • the tool is fully controllable by programming through any computer.
  • the present embodiment shows a cutting element (2) in a cylindrical shape
  • the tool allows interchangeable cutting elements (2) to collect samples of different size and shape.
  • the invention has been designed to include the option of biological decontamination of the tool by immersion (for example in Ethanol).
  • a box with IP67 protection index such as that offered by the manufacturer Fibox with Reference ABS 95/50 LG
  • an entry for the cables of the cable has been added to the box control using an IP68 threaded cable gland such as that of the manufacturer RS (Code RS 444-2955) and a cable duct such as that of the manufacturer Adaptaflex Reference PAFS13 / BL / 10M, to seal the output of the shaft (4) of the motor (7)
  • It uses a sealing joint for shafts like that of the manufacturer RS Reference 10X19X7 NBR. With this it is possible to isolate the motor (7) and the electrical part to be able to immerse the tool.
