Definitions
- the present invention relates to the field of single-sided or double-sided processing machines. More specifically, the present invention relates to the loading step of these single-sided or double-sided processing machines.
- polishing namely making the reduction of the roughness of a surface
- grinding namely the removal of material produced by a large number of grains of abrasives, sometimes agglomerated, which act as cutting tools
- the invention therefore particularly including, but not limited to, grinding machines or grinding, lapping and polishing.
- the invention therefore relates to the treatment of parts including, but not limited to, the processing of metal parts,
- steel parts stainless steel or not
- copper alloys titanium, aluminum alloys, tungsten carbides, precious metals, glass, crystals, ceramics, composites, synthetic materials, natural materials ....
- this loading technique takes a significant time during a complete cycle of the processing machine which comprises the following steps: loading - treatment - unloading.
- JP2000135672 describes a technique for filling the windows of the workpiece with a rotary loader mounted above the workpiece holder and having vertical storage rooms, these housing being distributed so as to come under the windows. Such a technique requires sufficient space in the machine above the door piece and is not suitable for all geometries of parts and workpieces. In addition, the geometry of a loader in particular is only suitable for a given pair of workpieces and workpiece holders.
- JP2012076191 describes a technique for filling the windows of the workpiece with a specific workpiece, formed of two superimposed plates, pivotally attached at their center, and having the same geometry and distribution of the openings for the housing of rooms.
- a first loading position the relative angular position between the plates is chosen so that the openings of the plate
- An object of the present invention is to provide a system and a method of loading parts in a coin processing machine free of limitations of known techniques. In particular, we seek a solution reducing the loading time of the parts in the machine.
- Another object of the invention is to provide a simple solution to implement, not modifying the tools and facilities
- a plate-shaped workpiece holder for holding at least one workpiece comprising a second face and a first face, said first face being flat, and said workpiece defining at least one through opening forming a cell for housing at least one workpiece, and
- the lower plate and / or the upper plate is set in motion. This generates, in the case where the film is in contact with the plate a friction between the film and the plate of the machine in contact with the film, which allows to use and destroy the film whose constituent (s) ( s) evacuates naturally out of the processing machine.
- the film disappeared and the parts are in direct contact with the worktable (lower tray or upper tray) according to the usual processing procedures.
- the loading time, and therefore the shutdown time of the processing operations is greatly reduced.
- the loading time is reduced to the loading time of the workpiece carriers in the machine, the parts already being loaded in the workpiece holder.
- the applicant company has tested that this solution in some cases reduces the loading time of the machine of the order of six, for example from six seconds to about one second.
- This solution also has the great advantage over the prior art of not modifying the tool, namely the workpiece holder, already used or having to adapt the single-sided or double-sided processing machine.
- the invention also relates to a process for loading workpieces in a single-sided or double-sided workpiece processing machine which comprises at least one lower plate intended to come into contact with the lower face of said workpieces, comprising the steps following:
- a plate-shaped workpiece comprising a second face and a first face, said first face being planar, and said workpiece defining at least one through opening forming a cell for housing one or several room (s) to be treated,
- the present invention also relates to a coin processing method in a single-sided or double-sided machine, comprising the charging method as described in the present text, wherein during the step of mounting said assembly of loaded loaded parts directly on the lower plate of the processing machine, is placed the first face of the workpiece holder on the lower plate so that the film is in contact with lower plate, and further comprising the step of processing said parts with said processing machine, whereby during the start of the treatment the film disappears and the parts come into direct contact with the lower plate during the end of the treatment.
- the present solution does not lead to adaptation of the workpiece processing step, and in particular no additional step to remove or remove the film, which usually degrades during of the processing step as will be discussed in more detail below.
- it is for example the friction between the film of the loading assembly and the plateau of the processing machine in contact with this film which allows the natural and automatic withdrawal.
- a film that is soluble in said liquid it is possible to choose a film that is soluble in said liquid.

- FIG. 1A is illustrated in perspective the mounting of a film 20 on a workpiece holder 12 shown in a vertical position: the film 20 is attached to the first face 12a of the workpiece holder 12 (lower face or upper face during treatment ).
- the workpiece holder constitutes a plate for holding parts in position during their treatment in a single-sided or double-sided processing machine, and delimits for this purpose at least one window in the form of a through opening that is called "alveolus”.
- the illustrated carrier has the shape of a disc with a central opening 13 at the center of the workpiece holder 12 and openings 12 distributed around this central opening, here eight openings 14 placed every 45 °.
- the workpiece carrier 12 has a circular contour and a center.
- a workpiece is for example a satellite comprising a contour with a toothing (not shown), so as to mesh with a corresponding toothing of the system
- the first face 12a is flat, in order to facilitate the laying and holding of the film 20 against this first face 12a.
- the first face 12 of the workpiece carrier 12 will come flat on the upper face, also flat, of the lower plate 40 of the processing machine.
- the second face 12b (often intended to be turned in the opposite direction to the lower plate, and to be turned towards and placed against the upper plate in the case of a double-sided treatment) and the first face 12a of the holder are parallel to each other.
- the workpiece holder 12 comprises cells 14 regularly distributed around the center, but it is possible to design other arrangements of the cells 14 on the workpiece carrier 12, just like other forms for the outline of the workpiece, and the presence of
- the central opening 13 is not systematic.
- the film 20 may be formed in advance and attached to the first face 12a of the workpiece carrier 12 or may be formed directly on the first face 12 of the workpiece carrier 12.
- the film 20 is formed in advance, and reported ( Figure 1A) against the first face 12a of the carrier 12 and held against this first face 12a ( Figure 1B).
- the film 20 is made of a water-soluble material, and in this case a simple moistening with water of the first face 12a of the workpiece carrier 12 and / or the face of the film 20 intended to come against the first face 12a of the workpiece holder 12, then makes it possible, during the contact between the film 20 and the first face 12a of the workpiece carrier 12, a sufficient adhesion and a subsequent maintenance of the film 20.
- the film is soluble, preferably water-soluble or fat-soluble.
- soluble preferably water-soluble or fat-soluble.
- water-soluble is polyvinyl acetate (PVA) or polyvinyl alcohol (PVAL), or other water-soluble resin, or a mixture of these water-soluble materials.
- PVA polyvinyl acetate
- PVAL polyvinyl alcohol
- the workpiece holder 12 comprises a plurality of cells 14 and the film 20 covers all the cells 14 in the loading assembly 10.
- the carrier 12 comprises a plurality of cells 14 and separate films cover the cells 14.
- a restricted film 21 covers two cells 14 and two isolated films 22 and 23 each completely cover a different cell 14, to form a loading assembly 10 '.
- the films 20, 21, 22 or 23 are continuous, namely solid. In other possible examples and not illustrated, these films 20, 21, 22 or 23 are perforated, or discontinuous, as long as they allow, once fixed on the first face 12a of the workpiece carrier 12, to support the weight of the piece 30 housed in the cell 14 of the workpiece carrier 12, that the presence of the film 20 allows to maintain during different conditions
- It can be an open network structure, with openings, woven or otherwise.
- the film is formed directly on the first face 12 of the workpiece holder 12: for this purpose, a projection of a liquid solution on the first face 12a of the workpiece carrier 12, followed by drying, these operations possibly being repeated several times, lead to the formation of a perforated film 20 in the form of an interlacing or a network of filaments.
- the above-mentioned water-soluble materials can be used as well as other water-based or non-aqueous solutions: for example and in a nonlimiting manner, it is possible to use a solution of sugar, salt, milk, organic materials (garlic, etc.) which makes it possible to constitute such a film after drying.
- FIG. 2A the loading assembly 10 (film 20 mounted under the first face of the workpiece carrier 12) is provided (FIG. 2A). Then, as it appears in FIG. 2B, the pieces 30 are placed in the cavities 14. In this FIG. 2B, there is shown a piece 30 per cell 14 but it is possible to envisage placing two or
- a fixing solution consists in moistening a face of the part that will "stick" on the film 20.
- the parts 30 are (temporarily) attached to the door -Piece 12 through the film 20 and, in this case, can be loaded on the machine the workpiece carrier with film and parts, with the film 20 disposed at the top or bottom of this set.
- the loading assembly 10 (the workpiece holder 12 covered with the film 20) loaded with parts 30 (Figure 2B) is arranged directly on the lower plate 40 of a machine of
- the upper plate 50 is lowered on the workpiece or (s) 12 in order to close the processing machine. Then the treatment starts with the implementation
- the unloading of the parts of the processing machine is not illustrated, but it is carried out as in the prior art.
- the workpiece holder (s) 12 are removed by hand and the treated parts are slideably driven out of the lower plate 40, in a storage bin for example waiting for another operation on these parts (another processing operation within the meaning of the present invention, or other machining operation, cutting, mounting.).
- FIGS. 3A to 3E respectively correspond to situations similar to those described previously with reference to FIGS. 2A to 2D. Then, as illustrated in FIG.
- the treatment is started, with the addition of a liquid 61 between the trays 40 and 50 (working space), in particular in the form of an abrasive suspension, which can in particular be hydrophilic or hydrophobic.
- a nozzle 61 serves as a liquid supply means.
- the processing machine is of the double-sided type and comprises a lower plate 40 and an upper plate 50 intended to come into contact respectively with the lower face and with the face. upper part of said parts 30, at least one of said plates being movable in its plane, and the method according to the invention further comprises the following step:
- FIGS. 4A to 4D In the case of the charging and processing processes illustrated in FIGS. 4A to 4D, as in the case of FIGS. 2A to 2E, no liquid is used for the treatment: it is a Dry destruction of the film 20 during the start of the treatment.
- FIGS. 4A to 4C respectively correspond to situations analogous to those described previously with reference to FIGS. 2A to 2C.
- the parts 30 always rest on the film 20, itself resting on the upper face of the lower plate 40 of the machine. In this case, since it is a single-sided processing machine, an upper plate is not used.
- the treatment is started by setting the lower plate 40 in motion relative to the frame of the machine (not shown). Such a movement is symbolized by the arrow 41, and remains in the plane of the lower plate 40.
- This movement can be for example an alternating movement of going and returning in a rectilinear translation, or a rotational movement of the plate, or still a combination of these movements.
- This movement of the tray (s) 40 and 50 is optionally accompanied by a movement of the workpieces 12 in their recess 14.
- FIGS. 5A to 5D respectively correspond to situations analogous to those described previously with reference to FIGS. 2A to 2C.
- the treatment is started, with the addition of a liquid 61 above the tray 40 (working space), in particular in the form of an abrasive suspension, which can in particular be hydrophilic or
- a nozzle 61 serves as a liquid supply means.
- FIG. 7 shows the case of this variant with film 20 at the top, once the loading assembly 10 loaded with parts 30 mounted on the lower plate 40 (as in FIGS. 2C, 3BC, 4C, 5C), in this case the parts 30 are directly in contact with the lower plate 40 of the machine: thus, if it is a single-sided machine, only the underside of the parts is treated and without friction between the film 30 and the machine trays, the film may not be destroyed: in this case, it will be possible to remove the workpiece holder 12 of the machine with the parts still secured to the loading assembly. It is then sufficient to separate each piece 30 of the film after the treatment.
- FIG. 8 shows the case of this variant with film 20 at the top, once the loading assembly 10 loaded with parts 30 mounted on the lower plate 40 and the closed machine with a top plate 50 (as shown in FIG. in Figures 2D and 3D), in this case the parts 30 are directly in contact with the lower plate 40 of the machine and the film 30 is in contact with the upper plate 50.
- the friction between the film 30 and the upper plate of the machine (with or without liquid supply) that will destroy the film if it is a double-sided machine and it is in this case the friction between the film 30 and the upper plate of the machine (with or without liquid supply) that will destroy the film.
- the film 20 is soluble and at the start of the treatment of the parts 30, the liquid supply 61 is also provided in the zone of
- the liquid may be only water, hot or cold, or an abrasive suspension.
- the abrasive particles may be various and are those conventionally used, in particular diamond powders, silicon carbide (SiC), alumina (Al 2 O 3), cerium oxide, alone or as a mixture.
- a loading assembly 10 is formed which allows the parts 30 to be held in the workpiece holder 12. It is therefore possible to prepare the advance and store the load sets 10 loaded with parts 30, and then place them in the processing machine. Time to
- the parts 30 extend essentially in two dimensions, in particular with two plane parallel faces between them.
- plane in the general geometric sense, roughness that may exist.
- parallel in the general geometric sense, in the limit a possible maximum relative inclination of the order of 5 ° between the two faces considered.
