Definitions

  • This invention concerns a device to unscrew bolt-nut assemblies on platelayer waggons for rails.
  • the invention also concerns a platelayer waggon for rails which employs such device.
  • such known machines are intended to remove the above cited components, already disassembled, from railway lines, for instance when existing railway lines are being dismantled.
  • patent FR-A-2.118.602 discloses a machine with magnetized crosswise strips to collect the above components. Such magnetized strips send the bolts, nuts, etc. to a central sorter conveyor belt, which carries these components to a set of collection stores.
  • Patent FR-A-2.388.086 is also known and discloses a self-propelled machine to remove clips, bolts, etc. from existing railway lines.
  • the machine comprises in its lower part some magnetized rollers to collect the above components, which are already disassembled.
  • the magnetized rollers take the components thus collected to transverse conveyor belts, which in turn cooperate with a central conveyor belt that delivers clips, bolts, nuts, etc. to a sorting or collection station.
  • the nuts are unscrewed by these rotating heads while the operator is keeping the bolts still with his hand.
  • the bolt is introduced by the operator by hand into a guide for bolts.
  • the present invention has the purpose of improving the unscrewing operation by making it semi-automatic;that is to say, according to the present invention the operator has the sole task of taking the bolt-nut assemblies, namely a bolt and a nut partly meshed together,and introducing them into the unscrewing device of this invention.
  • This unscrewing device conveys the bolt-nut assemblies along a path where appropriate rotation means act on the nut and cause it to become unscrewed and to drop into an appropriate collection guide.
  • the bolt and nut are conveyed along different guides.
  • the bolts run along the whole active tract of the unscrewing device of the invention and are gathered at the end of the same within a guide which delivers the bolts to a first work station of the machine.
  • the nuts,instead, being separated from the bolts by the unscrewing device of this invention, are delivered in an appropriate guide.
  • This latter guide delivers them to the last work station of the machine so as to be screwed onto the bolts and fastened definitively.
  • the invention has the purpose of automatically unscrewing and separating the bolt-nut assemblies into their constituent nut and bolt parts in such a way that the operator has only to perform an initial loading action.
  • a further purpose of the invention is to cause the nuts and bolts to be introduced automatically into their respective guides and to be delivered in the same to their respective work stations.
  • a further purpose of the invention is to ensure that when the nut leaves its guide, it is positioned with its most integral portion of screw-thread towards the bolt, which is already located on its seating in the plate.
  • the invention therefore arranges for the nuts to be turned upside-down while being collected after being unscrewed.
  • this is obtained by providing the guide of the nuts with a development such that at the end of such guide the nut has been turned upside-down as compared to its initial position; that is to say, the portion of the nut meshed earlier with the bolt is facing downwards and is therefore, in any event, presumably in good condition.
  • the device of the invention includes a conveyor, which consists of a chain means in a preferred embodiment.
  • This chain means has on its periphery means able to grip the stem of a bolt-nut assembly introduced into it by the operator.
  • Such latter means may consist, for instance, of a series of peripheral plates solidly fixed to the links of the chain.
  • the bolt-nut assembly is drawn along to the straight tract, where it is gripped between the plates, which have come close to each other in the meanwhile.
  • the bolt-nut assembly is drawn next along the conveyor, and the nut slides against a series of unscrewing means which consist advantageously of rubber or another material with a high coefficient of friction.
  • the nut is unscrewed from the end of the bolt and drops and slides through the force of gravity down collection chutes, which convey it to the guide that delivers it to its work station.
  • This invention is therefore embodied with a device to unscrew and deliver bolt-nut assemblies on platelayer waggons for rails, which carries out the separation of nuts and bolts from bolt-nut assemblies introduced by an operator into such device and also sends such nuts and such bolts to separate work stations, the device being characterized by including in cooperation:
  • the invention is also embodied with a platelayer waggon for rails which is characterized by employing a device thus constituted to unscrew and deliver bolt-nut assemblies.
  • a device 11 of a platelayer waggon 10 is located so as to correspond with an operator's cab 31.
  • An operator 15 takes bolt-nut assemblies 21 from a store 14.
  • the invention provides advantageously for two stores 14, one on each side of the cab 31.
  • the outlets of these stores 14 are immediately within reach of the operator 15 on each side.
  • the operator 15 takes bolt-nut assemblies 21 from the lateral outlets of each of the stores 14 and positions these assemblies 21 by hand within the device 11 at its loading end 111.
  • Fig.l shows a guide 12 for bolts, which is located at the end of the device 11 and delivers bolts 23 separated from their respective nuts 22 to a station 17 for the depositing of bolts.
  • a guide 13 for nuts located near the first end 111 of the device 11 delivers nuts 22 separated from their bolts 23 to a station 18 for the depositing of nuts.
  • ⁇ ig.1 shows also a positioner trolley 16,which has the task of screwing the nuts 22 onto their respective bolts 23 deposited earlier at 17; however, this positioner trolley 16 does not form part of this invention and will therefore not be described further.
  • the guide 13 for nuts includes an initial tract with a bend 113.
  • the nut 22 has been separated from its bolt 23, it has to run along this tract 113 and is thus turned upside-down so that its portion of screw-thread meshed earlier with the bolt 23 is facing downwards.
  • the nut 22 is then delivered to the station 18 where it is deposited.
  • the end tract of the guide 13 comprises a spiral development from a substantially central position towards the outside of the platelayer waggon 10.
  • Fig.2 shows how the bolt-nut assembly 21 is introduced at the end 111 of the device 11 and is gripped by engagement means 20 which are borne and moved by a conveyor 19.
  • the conveyor 19 consists of a chain but could consist of equivalent means such as a belt or band, for instance.
  • the engagement means 20 in this example consist of plates solidly fixed to links of the chain 19.
  • the chain 19 is drawn by means of a powered sprocket wheel 25 and a driven wheel 26.
  • the drive wheel 25 is powered in a known manner, by an electric motor for instance.
  • the plates 20 are spread apart as compared to their reciprocal position in the straight tracts of the chain 19. This facilitates the introduction of the bolt-nut assembly 21, which is then held by means of seatings 120 of a circular shape provided in the engagement plates 20. In this way the bolt-nut assembly 21 is gripped and drawn along the chain 19.
  • unscrewing elements 27 consist advantageously of a material which is at least partially resilient and has a high coefficient of friction.
  • Such chutes 28 comprise a suitable backwards slope, owing to which the nut 22 slides into the curved portion 113 of the guide 13 (see Fig.l) and is then delivered to the station 18 where it is screwed onto a bolt 23.
  • the bolt 23, still in such a position, is delivered to the station 17 for the depositing of bolts.
  • the unscrewing elements 27 are positioned on each side of the device 11 so as to obtain an anticlockwise rotation of the nuts 22 on both sides of the device 11.
  • the elements 27 are positioned on the outside of the device 11 in the lefthand part of the device 11,whereas they are positioned on the inside in the righthand part of the device 11; in this way an anticlockwise movement of the nuts 22 is always obtained.
  • unscrewing elements 27 are envisaged as being separate from each other, but it is possible to envisage elements 27 solidly fixed together, such as corrugated elements or ridges or projections belonging to one single element positioned alongside the path of the conveyor 19.
  • the present device 11 provides for the automatic sorting and elimination of faulty bolt-nut assemblies 121 (see Fig.4).
  • the bolt-nut assembly 121 is not separated into a nut 22 and bolt 23 by the unscrewing elements 27.
  • the bolt-nut assembly 121 therefore pursues its course, remaining held in the seating 120, and completes a full turn about the wheel 25.
  • the bolt 23 cannot fall into the guide 12 for bolts since it is withheld by the nut 22 against the engagement elements 20; the bolt-nut assembly 121 therefore continues on its course in the lower branch of the device 11 until it 121 encounters a discharge rib 29 at the end 111 of the device 11.
  • the inclined surface of the edge of the discharge rib 29 acts against the shank of the bolt 23 and creates a sideways thrust which discharges the bolt-nut assembly 121 from the engagement means 20.
  • the faulty bolt-nut assembly 121 is collected in a station 30 for the collection of faulty bolt-nut assemblies, from which the operator 15 can take it 121 by hand and put it, for example,into an appropriate tray or examine it for re-cycling.
  • the lay-out of the device 11 and its inclination and sizes can be varied. It is possible to employ a chain means 19 of a type other than that shown, as well as unscrewing elements 27 embodied with a form different from that described and shown.
