Definitions

  • the present invention relates to the polishing of the inner wall of cylindrical tubes, in particular for medical use.
  • the inner part may be the piston of a syringe whose outer tube would be the body, or the inner part may be an inner tube, such as the syringe body, in relative sliding with the outer tube so that it comes to cap one end of the inner tube, in particular to cover the needle of the syringe to prevent the manipulator is injured after an injection.
  • the lubricating agent thus introduced is a foreign body, the presence of which is often problematic for medical applications. There is therefore a need for another technical solution, to improve the sliding of a tube or an inner part in an outer tube without requiring the use of an additional lubricant.
  • the parts concerned are plastic parts manufactured industrially in very large series. Given the large number of parts to be produced, the technical solution sought must be both simple, inexpensive, and immobilize each piece for a short period of time; this solution must also be part of a highly automated industrial manufacturing process and at very high production rates.
  • the invention aims to overcome these disadvantages by providing a simple and reliable way to polish the inner wall of cylindrical tubes, in particular for medical use.
  • a first object of the invention is to provide a device for polishing the inner wall of cylindrical tubes, in particular for medical use, characterized in that it comprises a manipulation system to enable movement to be made. relative between a shuttle and a polishing tube for polishing an inner wall thereof, a movement in which the shuttle passes from one end of the tube to the other passing therethrough; said polishing shuttle having a longitudinal axis, and having axially flexible radial projections adapted to come into contact with the inner wall of the tube to be polished when the shuttle is inside thereof, and such as in a longitudinal section the sections of said projections form a series of undulations separated from each other, the peak-to-peak height of these undulations being greater than the distance between two successive undulations.
  • said device further comprises a tube holding tool capable of holding a tube during its polishing, and a system for supplying and removing polished and polished tubes respectively; moreover, said relative movement between the shuttle and the tube to be polished is a movement of the shuttle relative to the tube.
  • the invention also relates to a shuttle having a longitudinal axis for polishing the inner wall of cylindrical tubes, in particular for medical use.
  • the object of the invention is achieved by virtue of the fact that the shuttle comprises flexible radial projections in the longitudinal direction, able to come into contact with the inner wall of a polishing tube when the shuttle is inside of it. ci, and such that in a longitudinal section the sections of said projections form a series of undulations separated from each other, the peak-to-peak height of these undulations being greater than the distance between two successive undulations.
  • the projections Because of their relative height, the projections have a slender shape in the radial direction, which gives them a certain flexibility in the axial direction. In general, the projections extend in a substantially radial direction. However, depending on the type of polishing desired, the projections may also be inclined (generally only slightly inclined, for example a few degrees) in the longitudinal direction, either forward or backward.
  • the sections of the projections form corrugations whose height is greater than the distance between two undulations.
  • the peak-to-peak height of said undulations is greater than twice the distance between two successive undulations.
  • the material of the projections is chosen according to that of the tubes to be polished, and more particularly according to the hardness of the inner walls thereof. It is chosen sufficiently flexible, so as not to create scratches on the inner wall of the polishing tubes; in addition, a good tear resistance is necessary to ensure the durability of the shuttle.
  • the projections are based on flexible composite material.
  • This material may be a homogeneous thermoplastic or thermosetting material, having a continuous structure and not formed in the form of grains (Projections whose material comprises 'polishing grains' of high hardness, embedded in a resin or a binder, are however also usable). As the material of the projections is thus a unique material, the manufacture of these remains simple.
  • the shuttle can allow the polishing of all types of plastic tubes, including thermoplastics such as polycarbonates, polyamides, polyethylene terephthalate (PET), etc. It can also be used for polishing the inner wall of glass tubes.
  • thermoplastics such as polycarbonates, polyamides, polyethylene terephthalate (PET), etc. It can also be used for polishing the inner wall of glass tubes.
  • the invention also relates to a method of polishing the inner wall of cylindrical tubes, particularly for medical use, well adapted to industrial constraints, and to avoid the use of a lubricant.
  • the method is particularly simple and can be largely automated.
  • the relative displacement between the shuttle and the tube, during which the projections of the shuttle are in contact with the wall, is sufficient to polish it.
  • the relative movement of the shuttle relative to the tube is a single round trip, for example in the case of tubes closed at one end.
  • the shuttle makes a single passage through the tube to be polished, entering the tube at one end and exiting at the opposite end.
  • the polishing process is then particularly simple.
  • This version of the method is more especially advantageous if the polishing tubes have an edge on the inner wall which must not be blunted.
  • This case is particularly present for many tubes having a shoulder having a non-return function, which serves to ensure that the relative movement between an inner part and an outer tube is stopped in one direction.
  • the method according to the invention implemented with passage of the shuttle only in the preferred direction of the tube, allows the polishing in an extremely simple and fast manner and without blunting or damaging the edge of the tube. the shoulder.
  • This shuttle has a longitudinal axis 16.
  • it comprises a shaft 14 disposed along the axis 16. It thus consists of two parts: an inner shaft 14 generally metallic or plastic, extending along its axis longitudinal 16 which is also its axis of displacement, and a polishing piece 15 of plastic.
  • the shaft 14 made of rigid material ensures the maintenance and support of the polishing member 15 more flexible, and allows the manipulation thereof.
  • the polishing shuttle has a form of revolution; it is more symmetrical with respect to its median plane PM perpendicular to its longitudinal axis. Because of this latter symmetry it can be used indifferently for a movement in one direction or the other.
  • the shaft 14 has substantially the shape of a cylindrical bar. It has a reception portion in its middle part at which the polishing piece 15 is placed. This median part can be limited by two shoulders 17A and 17B ensuring the axial blocking of the polishing piece on the shaft 15.
  • the increase in diameter at these shoulders should not be too large, to allow the polishing piece can be threaded onto the shaft 14 by passing over one of these.
  • the polishing piece may have a generally cylindrical through bore which extends along its axis and through which the shaft 14 passes.
  • the part 15 may more generally be attached to the shaft by any appropriate means, in particular being formed by overmoulding, which is compatible with both shoulders more marked than less marked, and with the absence of Shoulders, in particular when an internal connection is made between the shaft and the part 15, for example if they are made of compatible plastic materials.
  • polishing piece 15 especially when the polishing piece 15 is attached to the shaft 14, it may be a reusable part, the polishing piece then being a wear part, a consumable part.
  • gripping portions 11A and 11B On either side of the shoulders 17A and 17B respectively extend two substantially cylindrical gripping portions 11A and 11B. These gripping portions facilitate the handling of the polishing shuttle for use in a polishing device. In a more general manner any shape or structure allowing or facilitating the gripping can be used, whether for manipulation by pushing or pulling, and by mechanical means, by suction, or others.
  • the outer surface of the polishing member 15 comprises radial projections 12, able to come into contact with the inner wall 2 of a polishing tube 1 when the shuttle is inside thereof.
  • the projections are part of a cylindrical envelope 3, the diameter of which is slightly greater than that of the inner wall 2 of the tube to be polished.
  • the radius (A) of the polishing piece including the projections and measured from the axis 16 of the shuttle must correspond substantially to the radius of the inner wall 2 of the polishing tube 1 and be slightly greater than that -this.
  • the sections of these projections form a series of undulations separated from each other.
  • the peak-to-peak height (B) of these undulations is greater than the distance (C) between two successive waves.
  • the projections have substantially the shape of disks arranged one after the other along the longitudinal axis.
  • the projections have a helical shape.
  • a projection in a view along the axis of the shuttle, does not extend over 360 ° about the axis, but is divided or distributed on one or more radial angular sectors. In the latter case, it will advantageously ensure that projections axially cover the angular sectors left free by other projections, so that, taken together, the projections cover 360 °.
  • the projections may have the shape of waves or have a substantially sinusoidal profile.
  • the section width (E) of a projection may also be substantially constant or decrease as one moves away from the axis 16. Such a section width profile (E) decreasing facilitates in particular the manufacture of polishing parts by injection-molding because of the remains; it also gives good mechanical resistance to the polishing piece 15.
  • the longitudinal section of the projections may have a width of section (E) average or median less than the height (B) peak-to-peak thereof, and even less than half thereof .
  • the shuttle may comprise a metal shaft disposed along the axis thereof.
  • projections 12 are overmolded on said shaft 14 and it is reusable.
  • the projections generally constitute a single piece, in one piece, which can more particularly be overmolded on the shaft 14.
  • the projections 12 and the shaft 14 may in another embodiment constitute a single piece.
  • a longitudinal section of said projections it appears on at least one of said corrugations and substantially at the top thereof, at least one point contact zone 18 allowing a substantially punctual contact between the projection 12 and the tube to be polished. (the top of a ripple here designating the part of the latter furthest from the longitudinal axis).
  • the almost punctual contact made by the area 18 of point contact with the inner wall of the tube to be polished is allowed by the fact that the radius of curvature R of the corrugation measured in its longitudinal section is small, in particular with respect to the width E of the projection section.
  • the inner wall of the tube will be polished by making a relative movement between the shuttle and the tube to be polished, movement during which the shuttle passes from one end of said tube to the other through the tube. -this.
  • the tube to be polished is maintained.
  • the relative movement between the shuttle and the tube to be polished is then effected; this movement is a movement of the shuttle relative to the tube.
  • the tube is released.
  • a means such as in particular a tool 26 for holding tubes.
  • a tube 24B is first put in place by means of supply and removal not shown.
  • This polishing tube 24B is maintained for polishing in a holding passage 40 pierced through the tooling 26 and opening on two sides thereof 36A and 36B by two openings 36 and 38.
  • This tube comprises a cylindrical portion whose inner cylindrical wall must be polished, and a flared collar forming a shoulder at one end 32 of the cylindrical portion.
  • Maintaining the tube 24B in the holding passage 40 is on the one hand to the insertion of the cylindrical portion in the holding passage, but also to the abutment of the aforementioned shoulder of the tube against the 36B side of the tool 26, which prevents the tube from sinking into said holding passage 40 when the shuttle moves in the tube in the direction indicated by the arrow F.

  • the recovery of the shuttle would be directly in the vicinity of the second end 34 of the tube.
  • the movement of the shuttle relative to the polishing tube is thus a simple translation, inscribed along the axis of the tube. It is not necessary to provide more rotation.
