Definitions
- the present invention relates to a gripping device, clamp type. It also relates to a gripping system composed of such devices.
- the invention is particularly applicable to the capture and removal of fragile and sticky objects, for example for deformable food products on an agro-food manufacturing line.
- Automated food processing lines from the beginning to the packaging, generally require a large number of handling operations that entail gripping food products while meeting high hygiene requirements.
- a first type is the grip by pneumatic suction. These are all-or-nothing systems with unknown gripping forces that do not allow for product positioning errors.
- the take-up efficiency is low because of the large geometric variability of the objects handled.
- the removal efficiency is also low because there is no system that processes random bonding on the gripping tool and ensures a correct final position in the dispensing area.
- Another type is the gripping bi-digital clamp with two jaws symmetrical. There is no depositing system overcoming the problem of bonding and there may be failures of seizure or crushing of the product under ex-ante unbounded efforts.
- an object of the invention is to overcome the aforementioned drawbacks by allowing in particular the automated gripping of fragile, deformable and sticky food products while meeting the most stringent hygienic safety standards.
- the subject of the invention is a gripper device of the gripper type, comprising at least: a bar movable longitudinally along an axis of symmetry;
- said bar is provided at one end of a plate, length of said bar being such that said plate is able to push said object when said force U 'is exerted towards the jaws, the thrust being carried out simultaneously at the opening of the jaws.
- Said device is for example monolithic.
- Said beams having a fixed end are for example connected to a rigid part adapted to be fixed on a structure.
- Said beams are for example curved and non-parallel.
- Said beams connected to said bar comprise for example several rectilinear sections, the sections starting from the ends of said beams being parallel, said beams comprising for example three rectilinear sections.
- Said beams have for example non-constant sections, the sections being maximum at the attachment points of said beams and decreasing towards the center of said beams.
- Said jaws are for example flexible. They have for example a width allowing them to enter at least two objects at a time.
- the activation of said bar is for example carried out by means of a ring fixed at the end of said bar opposite said plate.
- the invention also relates to a gripping system comprising a set of devices such as that described above.
- Said devices are for example positioned in at least a double row, staggered.
- Said beams having a fixed end are for example fixed to a structure in the form of a plate.
- Said system is for example suitable for use in an agro-food chain, said object then being a deformable food product.
- FIG. 3 an illustration of the activation mode of a device according to the invention
- FIG. 6, a representation of the mechanical stresses likely to be experienced by an embodiment of a device according to the invention
- FIG. 8 a possible embodiment of the jaws of a device according to the invention.
- FIG. 9 a partial view the embodiment of an embodiment of a gripping system according to the invention comprising a set of previous devices;
- Figure 1 shows a first possible embodiment of a gripping device 10 according to the invention.
- the device is used to perform picking and drop operations. Several applications are possible.
- the device is formed in a deformable monolithic body, symmetrical with respect to an axis 100, comprising an ejection plate 5 and two jaws 4, 4 'forming a clamp.
- the movements of the plate 5 and the jaws January 1, 12 are controlled by four structures in the form of deformable parallelograms 1, 1 ', 2, 2', also called 4-bar systems. Subsequently, for simplicity we will call these parallelogram structures.
- a first pair of parallelograms 1, 1 ' symmetrical with respect to the axis 100, controls the movements of the jaws 4, 4'.
- the second pair of parallelograms symmetrical with respect to the axis 100, controls the movements of the plate 5.
- the two pairs of parallelograms interact with each other.
- the parallelograms 1, 1 'of the first pair are fixed to a structure 7.
- This structure is for example a part of a robot or any other automated device.
- Each fixed parallelogram is connected to a jaw by means of a rigid connection 3, 3 ', the latter being connected to the side 13, 13' of the parallelogram opposite said structure 7. Consequently, any movement caused on this side 1 1 , 1 1 'is transmitted to the jaw 4, 4'.
- the jaws can themselves be rigid or flexible, as needed.
- the parallelograms 2, 2 'of the second pair are connected on the one hand to the rigid connections 3, 3' and on the other hand to a bar 9 carrying the plate 5 arranged in a plane perpendicular to the axis of the bar, coinciding with the axis of symmetry 100.
- the bar comprises an actuation point concretized by a ring 8 in the example of FIG.
- This actuation point constitutes the entry point of the gripping device, the three outputs being the plate 5 and the two jaws 4, 4 '.
- the parallelogram structures are now more precisely described. In the remainder of the description, the parallelograms of the first pair 1, 1 'and the second pair 2, 2' upper parallelograms and lower parallelograms respectively will be referred to with respect to their respective positions.
- FIG. 2 shows a monolithic parallelogram structure 201 of the type of those 1, 1 ', 2, 2' used in the gripping device according to the invention.
- This parallelogram structure is composed of two opposite rigid sides connected by two flexible beams 23, 24 parallel. These beams act as a flexible guiding system by flexing at their hook points, while being stiff in traction.
- This parallelogram structure with flexible beams makes it possible to replace the guide 29 obtained by a poly-articulated parallelogram structure 202, with pivoting pivots.
- the flexible beams 23, 24 in flexion and stiff in tension allow to obtain guidance in pure rectilinear movements, that is to say, accurate, parallel to the other two sides 25, 26 of the parallelogram to which are hung the beams.
- Each upper parallelogram comprises two parallel beams 1 1, 12, 1 ', 12' connected on the one hand to the fixed side 14, 14 'and on the other hand to the opposite free side 13, 13' connected to the rigid connection 3, 3 '.
- this side 13, 13 ' is an integral part of the rigid connection.
- a rigid connection is thus composed of three parts: a horizontal part connected to the first pair of beams 1 1, 12, 1 1 ', 12', a vertical portion connected to the second pair of beams 21, 22, 21 ', 22', and a part which folds towards the axis of symmetry 100, the latter part carrying the jaw 4, 4 '. The length of this portion depends on the desired initial gap between the jaws.
- a deformation caused on the first upper parallelogram 1 causes a rectilinear movement 19, 19 'pure of its free side 13, 13'.
- This pure rectilinear movement is transmitted by translation to the jaw 4, through the rigid connection 3 according to the parallelogram guide described above.
- the same phenomenon occurs between the second parallelogram 1 'and the jaw connected thereto.
- Each lower parallelogram comprises two beams 21, 22, 21 ', 22' connected on the one hand to the rigid connection 3, 3 'connecting the upper parallelogram to the jaw, and on the other hand to the bar 9 connected to the plate 5.
- the side of the lower parallelogram is an integral part of the rigid connection 3, 3 '.
- the bar 9 integrates the other side of the parallelogram.
- the beams 21, 22, 21 ', 22' are directly connected to the rigid connection and to the bar.
- FIG. 3 illustrates the mode of activation of the device according to the invention.
- the device is controlled by a force U exerted on the activation point 8 in a rectilinear path along the axis of symmetry 100 in one direction or the other, in practice up or down.
- Figure 3 illustrates the case where the force is exerted upwards.
- Activation of the entry point causes the three output points 4, 4 ', 5 to move.
- the movement of the entry point upwards causes upward deformation of the lower parallelograms 2, 2' causing a deformation of the upper parallelograms 1, 1 '.
- An activation force exerted downwards causes the opposite rectilinear movements, that is to say a guidance of the plate 5 downwards and a guide of the jaws at a distance, and therefore a loosening.
- a device according to the invention has three positions:
- FIG. 4 illustrates the aforementioned positions by an input cycle and deposits a flexible object 40.
- the gripping device is that illustrated in FIGS. 1 and 3.
- This cycle comprises an approach phase 41, an object acquisition phase 42 and an object ejection phase 43.
- the plate 5 is not in contact with the object and the jaws are in the open position.
- the structure 7 on which is fixed the gripping device is for example a robotic arm whose movement is guided towards the object, causing the device to guide the object.
- the jaws arrive at the level of the object and the plate 5 touches the object.
- an activating force U is exerted on the activation point 8, in the opposite direction to the jaws 4, 4 ', causing the clamping 49 of the object by the jaws, acting as a clamp, and guiding the tray upwards.
- an opposite activation force ⁇ is exerted on the activation point 8, in the direction of the jaws, causing the opening of the jaws, therefore the loosening 49 of the object, and the guiding of the plateau 5 down to the jaws, the plate then acting as a push object.
- the displacement of the activation point in one direction or the other may be less than one centimeter, of the order of 7 mm for example.
- the gripping device according to the invention is under-actuated, that is to say it has more degrees of freedom than actuator.
- a single actuating point makes it possible to obtain, in a phase 42, the controlled tightening of the jaws around the object 40, then in a subsequent phase 43, a guaranteed translation deposit of the pusher plate 5 towards the object.
- the thrust exerted by the plate avoids the adhesion of the product on the jaws and allows precise positioning in a container for example.
- the intrinsic structure of the device according to the invention thus allows a combination of the opening movements of the gripping jaws 4, 4 'and the thrust of the plate 5, acting as a stripping tray. It is therefore a gripping device with an integrated stripping system that does not require external energy or a delayed stripping cycle.
- FIG. 5 shows another possible embodiment of a gripping device according to the invention.
- the beams 21, 22, 21 ', 22' of the lower parallelograms are no longer rectilinear. From a strictly geometrical point of view, these beams no longer form a parallelogram.
- this embodiment makes it possible to reduce the maximum stresses overall.
- the curved character makes it possible to reduce the actuating force, in fact this curved character increases the length of the beam thus flexibility in bending and therefore reduces overall all constraints.
- the non-parallel character makes it possible to symmetrize the distribution of the stresses between two beams facing each other.
- FIG. 6 is a perspective view of the gripping device shown in FIG. It illustrates by gray gradations the stresses exerted on the beams of the lower parallelograms.
- these stresses cause the breaking of the beams.
- the embodiment of FIG. 5 increases this lifetime by distributing in a more homogeneous manner the mechanical stresses exerted on the beams.
- each beam 21, 22, 21 ', 22' comprises three straight segments.
- the segments 21 1, 221, 212, 222, 21 ', 221', 212 ', 222' of the upper and lower beams connected to the rigid parts 3, 3 ', 9 are parallel on a section starting at these rigid parts.
- the shapes of the beams are symmetrical 21, 22, 21 ', 22' with respect to the axis 100 so as to allow suppression of the parasitic movements introduced by these non-parallel beams.
- non-parallel beams as illustrated in particular in FIG. 5, makes it possible to optimize the behavior of the system, in particular the ratio of the movements of the jaws 4, 4 'with respect to the plate 5, and to reduce the operating force. necessary to enter objects. Thus, the maximum stress is reduced and the life of the device is increased.
- the behavior of the deformation system which constitutes a device according to the invention, is directly a function of the stiffness of the flexible guides constituting the system, via the curvature of its beams and their stiffness in flexion and traction. Increasing the flexibility of beams in flexion, corresponding to the large clearance of the plate 5, reduces the actuation force and therefore the constraints involved.
- Figure 7 shows another embodiment of a device according to the invention which improves the homogenization of mechanical stresses on the bars. As shown in Figure 6, the stresses are not identical between the two beams constituting the same flexible guide.
- An objective of the optimization of the embodiment of FIG. 7 is to obtain a homogeneous stress in each beam. We act locally on the thicknesses to homogenize these constraints.
- variable sections are introduced into the beams of the flexible guides, at least on the lower beams 21, 22, 21 ', 22'.
- the stress is locally reduced.
- the thickness is increased at the places 71, 71 'where the stress is maximum, in particular the section is maximum at the points of collision of the beams on the rigid parts 9, 3, 3' and then decreases towards the center of the beams.
- variable section in particular has the effect of reducing stress concentrations within the same beam.
- the homogenization can not be perfect, indeed, it would be necessary to tend towards a thickness of zero beam in places of zero stress.
- the non-constant distribution of the volume or density of material along the longitudinal axis of the beams 21, 22, 21 ', 22', as illustrated in FIG. 7 makes it possible to better distribute and standardize the stresses along the entire length of the beams. beams and therefore further increase their service life.
- FIG. 8 shows another embodiment of a device according to the invention.
- the clamp 81 formed of the two jaws 4, 4 ' is designed to handle several objects 40, for example for gripping two objects.
- the jaws 4, 4 ' are widened. It is the same for the pusher plate 5.
- This type of embodiment is particularly advantageous in gripping systems comprising a plurality of gripping devices according to the invention in parallel for the gripping in parallel of a large amount of objects.
- a clamp 81 of the type of Figure 8 can also allow to grasp larger objects with stability.
- FIG. 9 illustrates, by a partial view, the principle of producing the system for gripping several objects in parallel, in particular in large quantities, for example several tens.
- a device 10 according to the invention elementary clamp we will call a device 10 according to the invention elementary clamp.
- the system of Figure 9 is composed of several elementary clamps.
- the jaws are widened as in the example of Figure 8.
- the elementary clips 10 are arranged in staggered rows. More precisely, they are arranged in double rows 91 only one of which is shown. In each double row, the clamps 10 are staggered as shown in FIG. 9 where only two pliers of a double row are shown. Such an arrangement is particularly advantageous for gripping and depositing objects in a housing, not shown, capable of containing at least two rows of objects.
- Each gripper allows the gripping of two objects, which doubles the handling capacity in relation to the number of grippers.
- 40 clamps 10, 80 objects can be manipulated.
- Figure 10 illustrates the complete system consisting of four double rows of ten clamps each, thus allowing the gripping of 80 objects.
- the clamps 10 are attached to a structure 7 at their upper parallelograms as shown in FIG. 1. This structure is for example a plateau.
- the elementary gripping devices, that is to say the grippers 10, are fixed to the structure 7 by the ends of the flexible beams 11, 12, 11 ', 12', for example via the rigid part 14 itself. even fixed on the structure.
- Recesses 101 are provided to pass a clamp activation mechanism, this mechanism exerting a force in one direction and the other on the activation point 8 of each clamp.
- the structure 7 is for example fixed to a robotic arm coupled to the activation mechanism producing a relative movement of the clamps relative to the structure.
- the actuator, or the activation mechanism may be the same for all the clamps 10.
- the approach, capture and ejection phases are those described with reference to FIG. 4, but for several tens of clamps in parallel with simultaneous movements.
- a gripping device is a deformable monolithic gripper manufactured in a single material compatible with hygienic design constraints.
- the material used may be a polymer of polyoxymethylene type, POM homopolymer or acetal copolymer, polyetheretherketone also referred to as PEEK, polyamide or polyimide.
- a device according to the invention is easily manufactured by deposition of molten polymer, or by laser cutting or numerical control cutting. All the components of the device and in particular the beams are machined in a single block of material.
- a device according to the invention is a flexible monolithic system, equivalent to a poly-articulated kinematic system, which does not require assembly, avoids fouling phenomena, facilitates cleaning and manufacture.
- it is inexpensive, reliable and reduced mass. Its lifetime is further enhanced by a clever arrangement and structure of beams.
- a single linear actuating force makes it possible, initially, to tighten two jaws on the object during the setting phase, and then to obtain, during the removal phase, a detachment and then a removal. Guided product thanks to the push plate. These movements are synchronized by the very topology of the mechanical structure of the device. The production cycles are optimized and the production rate improved.
