Definitions

  • the object about present request for industrial invention is a machine for realization of the "abrasive threads" used in cutting machines which are employed in block of marble cutting in a quarry or in a unworked marble yard processing.
  • Mentioned machines execute marble cutting through a particular "abrasive threads" dragged in rotation by flywheel of the electronic cutting machine.
  • the mentioned “abrasive threads” consists by a metal cable, which is characterized by ends tied together and threaded annular components.
  • Said threaded components may be: spacer rings, coil springs, or abrasive pearls, in accordance with a periodic sequence all over in length of the metal cable.
  • Above-mentioned machines allows to make vertical, horizontal, or tilt cutting through an hydraulic translation system for cutting machine moving.
  • abrasive threads is made only manually; said components, which have abrasive surface or not, are threaded in a metal cable following a required sequence.
  • Purpose of this invention is to achieve a machine for automatic assembly of the "abrasive threads"; in meaning to thread every said annular components in a metal cable.
  • Said machine comprises a "loader-body” which is a loader for some types of annular components.
  • Leading pipes on vertical axis guide annular components into cylindrical housings which are obtained inside a cylindrical drums.
  • Above "loader-body” lodges said drums that are revolving on horizontal axis.
  • Mentioned cylindrical housings consist by diametral loop holes which are executed on lateral surfaces of the said drums. Above cylindrical drums can rotate on horizontal axis in order to modify cylindrical housings alignment from vertical to horizontal axis.
  • Said "loader-body” implements a loop duct on horizontal axis that intersects vertical axis of the leading pipes, and horizontal axis of cylindrical drums which is aligned on perpendicular direction.
  • above cylindrical housings When above cylindrical housings is oriented on vertical axis, they are aligned to leading pipes.
  • said cylindrical drums turn on 90°, above cylindrical housings become oriented on horizontal axis and they are perfectly aligned to said loop duct into the "loader-body”.
  • Above-mentioned machine comprises, aligned at loop duct of the "loader body", a couple of pliers moving together on horizontal axis by sliding trolley, and a third pliers independent moving on the same side and on the same direction by another sliding trolley.
  • Said couple of pliers are designed to support and translate metal cable which should be kept coaxial at loop duct of the "loader body”. After said annular components threading, above third pliers translates them on metal cable, in order to enable another threading cycle.
  • Mentioned machine comprises, aligned at loop duct of the "loader body” and on other side respect said pliers, a threading bar which is constituted by a cylindrical pipe that can be translated on alternative moving in order to thread annular components.
  • Above threading bar have an external diameter lower than diameter of the loop duct in the "loader body", and an internal dimeter higher than diameter of the metal cable.
  • Said threading bar moves inside loop duct of the "loader body” from other side to thread a group of annular components on metal cable and to thrust outside of the "loader body” said annular components. In this stage inserted end of metal cable doesn't operate any movement and it is lodged into internal hole of threading bar.
  • Figure 1 shows, by axonometric schematic representation, said "loader body”, threading bar, and an end of the metal cable.
  • Figures from 2 to 10 show, by section on vertical plan H-Il of fig. 1 , the consecutive configurations that said elements of the mentioned machine are getting on threading cycle.
  • the machine according to the invention implements the "loader body” (1), on parallelepiped shape, which comprises two leading pipes (2) on vertical axis (Z).
  • Cross section of the leading pipes (2) allows to guide every associate annular components (3) which are designed to be threaded on the metal cable (4). Every leading pipes (2) arrive into corresponding cylindrical housings (5) obtained on lateral surfaces of the cylindrical drums (6) which are inserted into the "loader body” (1) and can rotate on horizontal axis (X).
  • Loop duct (7) passes through said "loader body” (1) on horizontal axis (Y) which intersects above-mentioned (X) and (Z) axes. Every said annular components (3) cross into circular section of the loop duct (7) which implements a suitable diameter.
  • Leading pipes (2), cylindrical housings (5), and loop duct (7) of the "loader body” (1 ) having the same diameter.
  • Said cylindrical drums (6) interrupt material continuity of the loop duct (7) until they turn on 90° on (X) axis in order to align above cylindrical housings (5) on said horizontal loop duct (7) on (Y) axis.
  • the above-mentioned machine implements a couple of pliers (8a and 8b) and a third pliers (10) which are displaced on one side respect at the "loader body” (1), where the metal cable (4) is situated.
  • pliers (8a) is more near to the "loader body” (1 ) than pliers (8b), distance between said couple of pliers (8a and 8b) is at least as total length adding of every length of the cylindrical housings (5).
  • Above third pliers (10) is positioned between said couple of pliers (8a and 8b), it is mounted on sliding trolley (11) and it can translates, independent of said couple of pliers (8a and 8b), on (Y) axis.
  • Said couple of pliers (8a and 8b) are provide by jaws which can tighten the metal cable (4) which is supported and translated for manually positioning and to carry out threading cycle. Mentioned third pliers (10) can't quite tighten the metal cable (4) by its jaws so that it implements annular components (3) sliding after threading stage.
  • Both sliding trolley (9) and (11) be able to achieve moving to or away march from the "loader body” (1).
  • the end (4a) of the metal cable (4) is displaced out side of the pliers (8a) in order to thread the first of annular components (3) in the loop duct (7) after the sliding trolley (9) has been completed moving to the "loader body” (1).
  • Above-mentioned machine provides a threading bar (12) on other side of the "loader body” (1) respect said pliers (8a, 8b, and 10).
  • Mentioned threading bar (12) is a cylindrical pipe aligned to horizontal (Y) axis, coaxial at loop duct (7) of the "loader body” (1) and it is characterized by an external diameter lower than diameter of the loop duct (7) and an internal diameter higher than diameter of the metal cable (4).
  • Said threading bar (12) has a total length higher than length of the loop duct (7) and it can move inside the loop duct (7), on (Y) axis, in order to thrust the annular components (3), which are lodged in the loop duct (7), out of the "loader body” (1).
  • the machine provides a electronic control system which is designed to activate and monitor every operating device on correct sequence in order to achieve automatic assembly of the annular components (3) along with the metal cable (4).
  • wile pliers (8a) is opening, threading bar (12) moves inside the loop duct (7) until its working extremity is displaced over the opened jaws of the pliers (10); every annular components (3) are ejected from the "loader body” (1) and all together are threaded into metal cable (4), as showed in fig. 6; d) threading bar (12) moves back from the loop duct (7), pliers (8a) is tighten and pliers (10) is closed, as showed in fig. 7; e) sliding trolley (9) and (11) move back in order to extract end (4a) of the metal cable (4) from the loop duct (7), as showed in fig. 8; f) pliers (8b) open its jaws, as showed in fig. 9; g) sliding trolley (11) moves back until every threaded annular components (3) are displaced over the pliers (8b), as showed in fig.10.
  • Said annular components (3) may be on different external or internal diameters and length, according to used metal cable (4) and "abrasive threads" which would to be realized.
  • the diameters of the leading pipes (2) must be different for every annular components that should be loaded, the same for the associated cylindrical housings (5).
  • the loop duct (7) of the "loader body” mustn't be on constant diameter but it should be divided on consecutive sections with different diameters which are increasing on out put direction of the annular components. Every said section of the loop duct (7) should be associated at each cylindrical housing (5) and it have the same diameter.
