Definitions

  • the present invention relates to a conduit reservoir for receiving an electrical or optical cable or hose or other conduit for conducting or transmitting at least one of a fluid, a signal or power.
  • a cable reeling device in which a partition wall a winding cylinder in a first part with a first, larger diameter and dividing a second part with a second, smaller diameter.
  • a cable to be wound passes through a corresponding recess in the partition wall between the first and the second part of the winding cylinder.
  • the wound state are on the second part of the winding cylinder a few loose layers of a non-extendable part of the cable and on the first part of the winding cylinder several adjacent layers.
  • the first part of the winding cylinder is empty and the non-extendable part of the cable is wound in the second part of the winding cylinder in some closely spaced layers.
  • a sliding contact, as in the DE 1 574 306 A is unsatisfactory for many applications.
  • a sufficiently reliable transmission of electrical power or electrical signals for many applications is possibly possible with great effort.
  • Corresponding devices for transmitting optical signals or light output require significantly more effort and are only satisfactory possible if the optical axis corresponds to the axis of rotation at the coupling point.
  • An object of the present invention is to provide an improved conduit reservoir for receiving an electrical or optical cable or hose or other conduit for conducting or transmitting at least one of a fluid, a signal or power.
  • Embodiments of the present invention are based on the idea of designing a conduit reservoir in which a conduit can be inserted or removed from a conduit path by rotating a carrier such that the conduit is movable along the conduit path ,
  • This allows, in particular, a substantially symmetrical configuration of the line path, in which a line, starting from a central area, is simultaneously inserted into or taken out of two sections of the line path.
  • the resulting simultaneous shortening of both ends of the conduit may be modified by the movability of the conduit along the conduit path such that only one end of the conduit is shortened or lengthened, but at twice the speed.

  • the conduit reservoir like a conventional cable winder, is capable of receiving a conduit by rolling up, simultaneously shortening or lengthening the conduit from a central portion to both ends.
  • the recorded quantity or length of the line can be released again by rotation of the carrier in a second direction, which is opposite to the first direction.
  • a line received in the line reservoir is movable along the line path, particularly both at rest and at the same time rotating carrier and largely or completely independent of the amount of currently received from the line reservoir amount.
  • a movement of a line along the line path is meant a movement of the tight or taut line and without generating loose loops of undefined shape and arrangement.
  • the line reservoir is therefore also for multi-core or multi-core electrical or optical lines, for transmitting high-bandwidth electrical or optical signals, for light transmission cables for transmitting high-power light (for example, illumination light for endoscopy), for lines for compressed air, water, blood or other fluids suitable in which rotary unions can be realized at best with great effort.
  • the line reservoir may also be for hybrid transmission for simultaneous transmission electrical and / or optical signals and / or power and / or be suitable for fluids.
  • the guide devices comprise in particular a roller rotatable relative to the carrier.
  • One or more rollers defining the conduit path may allow a particularly smooth displaceability of a conduit along the conduit path.

  • a line reservoir as described herein includes a first stationary guide at a portion of the line path adjacent to the first portion of the line path, and a second stationary guide at a portion of the line path adjacent to the third portion of the line path.
  • the rollers on the carrier and the fixed guide means are arranged such that a first angle between a first position of the carrier, in which a guided by the first stationary guide means just touches a first roller on the first portion of the line path, and a second position of the A carrier in which the conduit guided by the second stationary guide means just touches a first roller on the third portion of the conduit path and a second angle between the second position of the carrier and a third position of the carrier in which the first stationary guide Direction guided line a first roll adjacent to the first roller on the first portion of the line path just touched, are substantially equal.

  • the carrier is in particular mounted so that a rotation of the carrier by 360 degrees with a axial displacement of the carrier is accompanied by a predetermined pitch.

  • An example of an arrangement of three rigidly connected plate-shaped components which form a rotatable carrier is described below with reference to FIGS FIGS. 13 to 15 described.
  • the opening 44 can be designed to be significantly larger than indicated in the figures.
  • the opening 44 is each formed so large that a connector at the end of a line 10 can be passed through the opening 44. This may allow the use of the conduit reservoir 20 with a conduit 10 already assembled and permanently connected to connectors or other means at both ends.
  • a tensile force on the line 10 is translated into a torque on the rotatable support 40 and vice versa.
  • the transmission ratio is determined by the length of the effective levers, ie the distances of the straight lines along which the line 10 between the stationary guide rollers 26, 27 and the stationary attachment 28 on the one hand and the rollers 51, 52, 53, 54, 71, 72, 73 on the other hand, and determines the axis of rotation 48 of the carrier 40. These distances or lever arms vary periodically during rotation of the carrier 40.
  • FIG. 9 shows a simple example of a line reservoir with only four rollers 51, 52, 71, 72 on a rotatable support 40.
  • the two rollers 51, 52, on the viewer side facing the plate-shaped member 42 define a first portion 31 of a line path.
  • the two arranged on the side facing away from the viewer side of the plate-shaped member 42 rollers 71, 72 and defined by this third portion 33 of the line path are not visible and therefore indicated only in dashed lines.
  • a line runs along substantially straight portions 34, 35 of the line path.
  • These straight portions 34, 35 are also shown in dashed lines with a different stroke length to distinguish them from the first portion 31 and the second portion 33.
  • line reservoir is a similar reduction in the variation of the transmission ratio between tension and torque achievable by the arrangement of the rollers on the side facing away from the viewer side of the plate-shaped member 42 relative to the arrangement of the rollers 51, 52, 53, 54 on the viewer side facing the plate-shaped member 42 is rotated by 45 degrees.
  • the stationary guide rollers 27 may be shifted relative to the rotational axis of the rotatable carrier 40 by 45 degrees.
  • FIG. 8 a similar reduction in the variation of the transmission ratio between tension and torque is achieved when the rollers on the side facing away from the viewer side of the plate-shaped member 42 is different than in FIG. 8 represented symmetrically to the rollers 51, 52, 53 at the the observer facing side of the plate-shaped member 42 are arranged, similar to that in the line reservoir of FIGS. 2 to 6 the case is.
  • the attachment 28 can be replaced by a mounted relative to the axis of rotation of the carrier 40 by 60 degrees or pivotally mounted attachment 29.
  • Another alternative is an arrangement of the guide rollers or fasteners in the same place - similar to that in the line reservoir of the FIGS. 2 to 6 the case is - when using the rotatable carrier 40 FIG. 8 with 60 degrees against each other twisted arrangements of the first portion 31 and the third portion 33 of the line path.
  • the conduit 10 passes twice over the roller 73.
  • additional guide means can be provided.
  • the roller 73 may have a circumferential groove of sufficient depth to receive multiple layers of the conduit 10.
  • FIG. 10 shows a schematic sectional view of a variant of the roller 72, which can lead multiple layers of the line 10.
  • the illustrated section plane contains the axis of rotation 77 of the roller 72. It can be seen that the circumferential groove 75 of the roller 72 is formed so deep that it can simultaneously lead up to three layers of the line 10.
  • FIGS. 11 and 12 show schematic representations of a line path, each with four rollers, as in FIG. 10 indicated, in each case three layers of the line 10 can lead simultaneously, in the first and in the third portion of the line path can be realized.
  • the drawing layers of the FIGS. 11 and 12 are parallel to the two planes in which the first and the third portion of the line path is located, and perpendicular to the axes of rotation of the carrier 40 and the rollers.
  • first section 31 solid line
  • the second section 32 dasheshed line
  • an area 34 dashex line
  • the third section of the line path is in particular - similar to the line reservoir FIG. 7 - symmetrical and largely parallel to the first section 31, but in the FIGS. 11 and 12 not shown. To distinguish the first portion 31, the second portion 32 and the portion 34 of the line path, these are, as mentioned, shown in two different textures.
  • FIGS. 11 and 12 show the carrier 40 in two different positions and situations. At the in FIG. 11 shown position, a maximum amount of a pipe is accommodated in the pipe reservoir.
  • the conduit is received in the entire first section 31 of the conduit path and each roller carries three layers of conduit. Accordingly, the line is in the whole in FIG. 11 not shown third section of the line path, wherein also in the third section each roller leads three layers of the line.
  • FIG. 12 illustrated situation is determined by rotation of the carrier 40 from the in FIG. 11 achieved situation by almost three (more precisely: two whole and 7/8) full turns in the clockwise direction.
  • the line is almost completely removed from the first section 31 of the line path and extends only in a short area of the first section 31 between the second section 32 and the area 34 of the line path.
  • the line will be in the in FIG. 12 shown situation only by a single role in the first section 31 of the line path. Accordingly, the line is almost completely out of the FIG. 12 not shown third section of the line path taken.
  • the carrier 40 can be further rotated by about one eighth of a full turn clockwise until the line is also from the last, in the situation in FIG. 12 the lead still leading role is completely lifted.
  • FIGS. 11 and 12 shows that using roles of the kind they are in FIG. 10 is shown, and can lead multiple layers of the line 10, the capacity of the line reservoir can be multiplied.
  • the advantages of the so-increased absorption capacity of the line reservoir come in particular when using a line 10th with a surface that ensures a low friction between the layers of the conduit 10, to advantage.
  • FIGS. 13 to 15 show an alternative embodiment of a line reservoir, in which the receiving capacity is also significantly increased.
  • FIG. 13 shows a schematic sectional view of a roller 52 in the first section 31 (see FIGS. 14, 15 ) and a roller 74 in the second section 33 of the line path of the line reservoir.
  • Each of the rollers 52, 74 has three parallel grooves each.
  • the roller 52 at the first portion 31 of the conduction path is disposed between a first plate-shaped member 41 and a second plate-shaped member 42, the roller 74 in the third portion 33 of the conduction path is disposed between the second plate-shaped member 42 and a third plate-shaped member 43.
  • the plate-shaped component 41, 42, 43 are rigidly connected to each other, in particular via the axes of rotation 57, 79 of the rollers 52, 74 defining waves, and together form a rotatable carrier 40th
  • FIGS. 14 and 15 show - similar to the FIGS. 11 and 12 only the sections and areas 31, 32, 33, 34, 35 of the line path and the circular contour of the carrier 40 (FIG. FIG. 14 ) or the plate-shaped components 41, 42, 43 ( FIG. 15 ).
  • the positions of the rollers required to define this routing path are obvious.
  • the sections and areas 31, 32, 33, 34, 35 of the line path are shown in different textures.
  • the drawing plane of the FIG. 14 is parallel to the plate-shaped components 41, 42, 43 and perpendicular to the axis of rotation of the carrier 40.
  • the plane of the FIG. 15 is parallel to the cutting plane of the FIG. 13 and to the axis of rotation of the carrier 40 and perpendicular to the plane of the FIG. 14 ,
  • first portion 31 and the third portion 33 of the line path each have a helical shape.
  • the first section 31 and the third section 33 of the line path are thus each approximately curves of constant pitch on a lateral surface of a cylinder, but not a circular, but an approximately square cross-section with rounded according to the radius of the rollers corners.
  • the second section 32 of the line path connects the first section 31 and the third section 33 through an opening in the second plate-shaped component 42.
  • the rollers 52, 74 and their axes of rotation 57, 79 are tilted by a small angle to allow a low-friction guidance of the conduit 10 in the spiral-like first and third sections 31, 33 of the line path.
  • the line is inserted at each role in the upper and middle, but not the lower groove.
  • the respective lowermost turn of the first section 31 and the third section 33 of the line path is not occupied by the line 10.
  • the line reservoir upon rotation of the carrier formed from the plate-shaped members 41, 42, 43 by a counterclockwise rotation (based on the illustration in FIG. 14 ) can receive a maximum amount of the line 10 by inserting the line in the respective lower grooves of the rollers.
  • the line 10 can be removed almost completely from the first section 31 and the third section 33 of the line path.
  • the carrier is in particular mounted so that a rotation of the carrier 40 by 360 degrees with a displacement of the carrier parallel to its axis of rotation by the distance between two adjacent grooves in one of the rollers 52, 74 goes along.
  • This helical or helical movement is also indicated by the arrows 85, 86.
  • guide plates 81, 83 may be provided for guiding the conduit, which are in FIG. 13 are indicated.
  • the guide plates each have a spiral-like shape on the first section 31 and on the third section 33 of the line path.
  • the line reservoirs 20 described here can each be provided with a tubular sterile coating or with a sterile sheath for the line 10.
