FR2648480A3 - Flat metal plate for supporting several spinning spindles - Google Patents

Abstract

This plate, acting as a support element for several spindles, located one after another in spinning frames (machines) is a substantially flat plate 3 formed of a single piece for a metal by a single stamping or cutting operation on a press. This single stamping operation also forms lightening openings 9 in the surface of the plate, through holes 7, and fastening holes for the optional elements of the spinning frame.

Description

FLAT METAL PLATE TO SUPPORT MULTIPLE PIN

WIRE

  The present invention relates to a flat metal plate for supporting several spindles one after the other in a continuous ring spinning machine, said plate being formed using a single

pressing operation.

  The structure supporting the load and forming the support frame of a loom is always susceptible of construction improvements which can essentially bring into play the type of material used and its

machining process.

  Such improvements may be motivated by the desire to reduce construction costs, improve and simplify installation, and more closely meet user simplification requirements in textile factories. The cast iron support plates for pins are well known. Due to their manufacturing process,

  these plates have a considerable thickness and weight.

  They also require subsequent cold machining using machines, such as machine tools working by removing chips, both to form the seats used for mounting and fixing the various operational elements of the spinning machine. and to remove burrs which are always present on metal molded parts. These various machining operations are made even more difficult by the considerable polds of such cast iron plates. In this regard, the operators of machine tools experience difficulties in their handling, all this contributing to

  increase the final cost of such support elements.

  In view of the above, the main objective of the present invention is to provide a support element the manufacture of which is considerably simplified in order to thus significantly reduce the cost of the complete ring spinning machine without damaging its

operational reliability.

  An object of the present invention is therefore to provide a metal support plate having a cost

considerably reduced.

  Another object of the present invention is to provide a support plate which does not require machining by machine tools working by

chip removal.

  In this regard, machining with chip removal is very expensive from the point of view of machine, equipment and time required, as is well known in the art. Another requirement which the present invention aims to satisfy is that the metal support plate must have a low weight to facilitate

the assembly of the complete loom.

  These objectives are achieved and these requirements are met by perfecting the support structure of a continuous ring loom, which is obtained by using a plate as a support element, this plate being a substantially flat plate formed in one piece from a metal by one

  pressing or cutting operation with a press.

  In its surface, the plate includes lightening openings used at the time for the passage of sleepers or bars used to join together and to align with each other a large number of plates spaced as well only for the passage of maintenance lines for blowing or extracting air

  required for each spinning pin.

  The plate also includes in its surface holes, namely one for the passage of the drive shaft which extends longitudinally along the entire spinning loom and the others for fixing consoles or squares to said plate in order to be used to secure and support the bar supporting the pressing arms, the rollers and the pulling system, the crosspiece supporting the spinning pins and the underlying crosspiece which supports and guides the belts

  automatic reel lifting equipment.

  The support plate also consists of two or more than two thin plates joined together

or placed one against the other.

  We will now describe the present invention with reference to the single figure of the accompanying drawing which shows an embodiment of the invention in a schematic view in axonometric perspective of the flat metal support plate associated with the various identical plates spaced one on the other, one after the other, so as to form the aligned modular sections which together constitute the frame of the loom

complete which supports the load.

  In this figure, the reference 1 designates a modular section of the support frame of the continuous ring spinning machine. Two consecutive support plates form a single modular section which comprises, at least approximately, a number of spinning pins equal to that of the pins of the other aligned modular sections; the reference 2 designates the support cross member for the spinning spindles, this cross member extending longitudinally along each face of the complete spinning loom to help connect to each other and align the modular sections 1; reference 3 designates the flat metal support plate according to the present invention, which plate is formed using a single press operation: reference 4 designates the bar supporting the pressure arms. This bar is associated and is supported by brackets or support brackets 12 fixed to the plates 3. The bar 4, one being provided for each working face, extends longitudinally along the entire loom, so as to be part of the support frame for the complete spinning loom; reference 5 designates a foot with the help of which the structure of the loom is supported and leveled on the ground: reference 6 designates a crosspiece which brings together the

  to each other the support plates 3 and aligns them.

  This crosspiece, which extends along the complete loom, crosses the lightening opening 9. This opening is also used for the passage of the conduits serving for the blowing and the suction of the air necessary for each spinning spindle : reference 7 designates the hole for the passage of the drive shaft (not shown) which extends longitudinally along the complete spinning loom for actuating the spinning pins; the reference 8 designates the support and guide cross member for the belts of the automatic equipment for lifting the reels. This crosspiece 8, extending along each spinning face, also contributes to connecting and aligning the support plates 3 and, therefore, the modular sections 1: the reference 10 designates

  the pressing arm connected to the bar 4 and supported by it

  ci to cooperate with the underlying draft system,

  as is well known in the art.
