Definitions

  • the invention relates to a device for inserting an elastic sealing ring equipped with a support ring into a groove, for example a pipe sleeve, with a pipe sleeve holder and a sealing ring magazine supplying sealing rings with separating device.
  • Sealing rings made of soft elastic rubber are provided with rigid support rings so that they fit securely in the groove provided, e.g. a pipe sleeve of a plastic sewage pipe is guaranteed.
  • the support rings hinder deformation of the sealing rings, as a result of which insertion into the groove of a socket pipe is relatively complicated. Deformation is necessary, however, because the outer diameters of the sealing rings are always larger than the nominal widths of the assigned pipe sleeves, through which the sealing ring can be inserted into a position corresponding to the groove.
  • the invention has for its object to provide a device with which sealing rings in pipe sleeves can be used easily and without excessive deformation.
  • a sealing ring guide part which is assigned to the discharge side of the separating device and has a guide track which is aligned with the pipe sleeve as an extension of a pipe sleeve held in the sleeve holder, by means of one which can be advanced along the guide track to the pipe sleeve, and thereby from Magazine to the guide part emitted sealing ring in the area of the groove in the pipe sleeve entraining tappet with a sealing ring pressing head, and by a following the tappet following insertable insertion punch, whose outer diameter is approximately equal to the inner diameter of the pipe sleeve.
  • the guide path of the sealing ring guide part ensures that the sealing ring carried by the drag tappet is correctly inserted into the pipe sleeve.
  • the drag tappet can be pushed forward until the sealing ring which has been taken along has reached a position corresponding to the groove in the pipe sleeve. Due to the action of the sealing ring pressing head of the tappet, the area of the entrained sealing ring which is in contact with the tappet is pressed into the groove and held there.
  • the subsequent insertion punch which practically presses through the sealing ring, also presses its free areas into the groove. Appropriate actuation devices can then be used to move the tappet and insertion ram back along the guideway into the starting position.
  • the guidance of the sealing ring within the guideway by means of a tappet has the advantage that the sealing ring is only slightly deformed during its insertion into the pipe sleeve, so that there is no longer any risk of breakage of the support ring located in the sealing ring.
  • the sealing ring guide part is advantageously a housing block, a through hole being provided in the housing block as the guideway.
  • the diameter of the through hole is expediently approximately equal to the nominal width of the to be arming pipe sleeve, wherein the pipe sleeve holder and the housing block within the device are assigned to each other such that the through hole in the housing block is aligned with a pipe sleeve held by pipe sleeve holder. Both the tappet and the insertion ram can be moved back and forth in the through hole.
  • a sealing ring emitted by a separating device then sits in the guideway in such a way that it stands in the path of movement of the advancing tappet and is inserted along the guideway with practically no transition into the pipe sleeve extending the guideway.
  • the housing block can be exchangeably held on the device. Housing blocks with different through holes adapted to the respective sealing ring diameters can thus be easily exchanged.
  • the housing block has a radial insertion slot for a sealing ring.
  • a sealing ring can be introduced into the guideway through this insertion slot.
  • the housing block is particularly advantageously arranged in the device in such a way that the through-hole lies horizontally, the radial insertion slot pointing radially upward.
  • a separating device for a sealing ring magazine can thereby be provided with a drop funnel, the mouth of which corresponds directly to the insertion slot, so that an individual sealing ring delivered falls through the drop funnel into the insertion slot and ultimately stands in the guideway in such a way that a lower section of the sealing ring can be gripped by the advancing tappet .
  • This alignment of the components has the advantage that special feed units are not required; because the sealing rings get into the device in free fall.
  • the tappet is preferably a round rod which can be displaced in the longitudinal direction and rotatable about the longitudinal axis, the free end of which has the pressing head. Due to the possibility of moving the round rod, the gripped sealing ring is pulled into the pipe sleeve and by rotating the round bar, for example by 180 °, the pressing head presses a section of the sealing ring into the groove provided in the pipe sleeve.
  • the drag tappet is therefore a component that takes over both the positioning of the sealing ring in the pipe socket and the difficult start of pressing into the groove.
  • the pressure head can be a radial projection at the free end of the round rod.
  • the pressure head is the free end of the round rod provided with a detached shoulder.
  • the tappet and insertion ram can be moved or advanced independently of one another, is according to one Further development is provided in the device that the insertion punch has a guide groove for the tappet.
  • the drag tappet can thus be moved independently of the insertion ram within the guide groove.
  • the insertion punch initially engages the sealing ring to be pressed into the groove where it is already pressed into the groove by the tappet
  • the insertion punch has a rounded oblique tip.
  • the oblique tip is attached to the insertion punch in such a way that the outermost projection, when the insertion punch is pushed forward, first engages over the section of the sealing ring which has already been pressed into the groove by the drag tappet.
  • the oblique tip is pushed more and more through the sealing ring, which is ultimately increasingly pressed into the groove, starting from the section already in the groove.
  • a cylindrical core protrudes from the end face of the oblique tip of the insertion punch, the diameter of which is approximately equal to the inside diameter of the sealing ring.
  • the core can be a deposit on the end face of the insertion die.
  • a plastic body has the advantage that, with relatively soft art material, mechanical damage to the sealing ring during the insertion process can be avoided.
  • Working cylinders preferably pneumatic cylinders, lend themselves to the device according to the invention because the components which actually insert a sealing ring perform rectilinear movements.
  • the drag plunger Since the drag plunger also has to perform a rotary movement, it has teeth in an area adjacent to the associated piston rod, which is in engagement with a toothed rack that can be moved transversely to the drag plunger.
  • the rack performs a linear movement, which can also be brought about by a working cylinder, as a result of which the rotation of the towing bar about its own axis is produced using structurally simple measures.
  • Fig.l the device with its most essential parts is shown in a sectional view. To clarify the mode of operation of the device, insignificant parts have been omitted or only indicated schematically.
  • a pipe sleeve holder 2 On a base plate 1 of the device, not shown, a pipe sleeve holder 2 is arranged, which can consist, for example, of actuatable clamping jaws, which are not described any further.
  • the clamping jaws can hold a pipe sleeve 3 so that a groove 4 formed therein, into which a sealing ring is to be inserted, assumes a predetermined position within the device.
  • 5 designates a guide part, which is designed here as a cylindrical housing body 6.
  • the housing body has a through bore 7, the walls of which form a guide track 8, which is aligned with the pipe sleeve 3 by appropriate alignment of the guide part 5.
  • the housing body 6 is held interchangeably by a screw 9 on the base plate 1 of the device.
  • a drop funnel 12 In the Housing body 6 is cut into a radial insertion slot 10, above which the mouth 11 of a drop funnel 12 is arranged.
  • a drop funnel 12 Through the drop funnel 12, individually dispensed sealing rings from a separating device of a sealing ring magazine, not shown, fall through the insertion slot 10 into the through bore 7 of the housing body 6 serving as a guide part.
  • Each sealing ring 13 is equipped with a support ring 14 and is approximately perpendicular in the guide part 5.
  • With 15 is an insertable through the through hole into the pipe socket 3 insertable stamp whose outer diameter corresponds approximately to the inner diameter of the through hole 7.
  • the insertion punch is designed as a rod which can be moved back and forth in the direction of the double arrow 16 by means of a working cylinder (not shown).
  • the end face of the insertion punch is designed as a bevel tip 17 by a bevel.
  • 18 denotes a cylindrical core which projects from the oblique tip and whose outer diameter is approximately equal to the inner diameter of a sealing ring 13 to be inserted into the pipe sleeve 3.
  • a drag tappet 20 is displaceably guided in the guide groove in relation to the insertion ram 15.
  • the tappet has a sealing ring pressure head 21.
  • the tappet 20 consists of a round rod, which is indicated in the direction of the double arrow 22 by means of the Working cylinder 23 can also be advanced in the longitudinal direction of the housing body 6 through the through hole 7 with respect to the insertion die 15 and which can also be rotated in the direction of the double arrow 24.
  • an indicated section 25 of the round rod serving as a tappet 20 is provided with an external toothing 26 which engages with a toothed rack 27 which can be moved perpendicular to the plane of the drawing by means of an indicated working cylinder 28.
  • insertion punch 15 is shown in a position which corresponds to the fully retracted starting position.
  • the tappet 20 is retracted by the working cylinder 23 to such an extent that it is almost completely sunk into the insertion punch 15, a sealing ring 13 engages in the insertion slot 10 in the guide part 5 by appropriate control of the actuating elements of the device.
  • the lower region of the thus in the through-hole 7 standing sealing ring is consequently in the path of movement of the advanced tappet 20.
  • the tappet is advanced by the working cylinder 23 with appropriate control until the lower region of the sealing ring 13 is in a position corresponding to the groove 4 of the pipe sleeve 3.
  • the working cylinder 28 is actuated, the tappet is then rotated so that its pressing head 21 moves the section of the sealing ring 13 into contact with it in the groove 4 Push in pipe socket 3.
  • the insertion die 15 is pushed forward, the oblique tip 17 of which gradually presses the remaining sections of the sealing ring into the groove 4.
  • FIG. 2 shows a front view of the insertion punch, viewed in the direction of the section line II-II in FIG. 1.
  • the same components are provided with the same reference numbers.
  • the front view shows the arrangement of the guide groove 19 for the tappet 20 in the insertion ram 15.
  • the rounded shape of the oblique tip can also be seen by applying corresponding roundings 29.
  • insertion die 15 is shown together with the tappet 20 in a side view, which illustrates the shape of the rounded portions 29 in the region of the oblique tip 17.
  • FIG 3a shows a perspective view of the pressure head 21 of the tappet 20. It can be seen that the pressure head is formed in the simplest way by a notched step 30.
  • Fig. 3b shows the right detail with the groove 4 and Sealing ring 13 of FIG. 3 in a working position of the device in which the tappet 20 is rotated by 180 °, the end portion 31 of the tappet 20 which has not disengaged, which has remained stationary, having pressed the sealing ring 13 into the groove 4.
  • the sealing ring is held by the tappet and subsequently the insertion punch 15 is pressed, the curves 29 of which on the oblique tip 17 ensure that the sealing ring gradually rolls into the groove.
