  • the wrapper roll assembly may include one or more wrapper rolls adapted to be positioned adjacent the mandrel during the initial wrap forming operation and moved away from the mandrel during the succeeding portion of the coiling operation.
  • the wrapper rolls may be mounted on a carriage displaceable relative to the mandrel, and often the wrapper rolls are supported by arms;
  • pivotal movement is imparted to the wrapper roll such as by hydraulic piston and cylinder components having opposite ends. connected one to the arms and the other to the carriage or coiling machine frame.
  • coiling machines of the character to which the present invention relates include one or more apron members cooperable with the wrapper rolls and mandrel in forming the initial wraps of sheet metal on the mandrel.
  • the apron members are generally mounted for pivotal movement relative to the mandrel by means arms of the apron members at one end and having their other ends pivotally, mounted on the carriage or machine frame.
  • removal and replacement of the wrapping rolls relative to the coiling machine has involved a considerable amount of time and work.
  • the removal and replacement operation required the un-bolting and subsequent re-bolting of numerous securing and driving parts including, in applicable cases, disconnection of the pivot arms for the rolls and- /or apronmembers.
  • removal and replacement requires'the complete removal of the wrapping roll carriage from the machine frame.
  • Such-a removal operation also requires many manual connecting and disconnecting operationswith respect to fasteners, pivot arms, and the actuating components of hydraulic piston and cylinder drive units.
  • the foregoing problems and others are overcome by providing a wrapper roll assembly and coiling machine support therefor which are structurally interengaged in a manner which enables convenient and expeditious wrapper roll removal and displacement operations. Accordingly, down time and production loss are minimized as are maintenance expenses. In this respect, a minimum number or preliminary operations are required by maintenance personnel prior to a removal operation and, likewise, a minimum number of operations are required by such personnel subsequent to a replacement operation.
  • the wrapper roll assembly includes a head member supporting the wrapper roll or rolls and the head member and rolls are removable as a unit from the supporting components of the coiling machine.
  • the head member and support component structure enable such removal to be achieved in a minimum amount of time, and the only preliminary operations necessary to achieve removal are disconnection of the drive shaft or shafts for the wrapper rolls and release of the head member from the support component. Removal and replacement of. the wrapper roll assembly is achieved, preferably, from one side or the other of the coiling machine along a linear path unobstructed by structural components of the coiling machine.

  • supporting head 30 of wrapper roll assembly 14 includes a support plate 57, and wrapper roll support arms 58.
  • Head 30 further includes a support plate portion for fixed guide member 34.
  • the latter support plate portion includes walls 59 and 61 extending forwardly from plate 57 and between arms 58, and a front wall 63 to which the guide member 34 is removably secured.
  • Support plate 57 has upper and lower edge surfaces 176 and 178, respectively. As will be seen in FIGS. and 13, surfaces 176 and 178 are inclined such that-the planes thereof converge in the direction from side, 20 of frame toward side 18 thereof. Preferably, surfaces 176 and 178 are provided with wear plates 177 of bronze or the like. Further, as best seen in FIGS. 1 and 5, surfaces 176 and 178 are also inclined such-that the planes thereof converge toward one another in the direction toward the mandrel axis.
  • the forward end of carriage 16 is provided with a support plate -179extending between sidewalls 149 and 151 of the carriage and plate 179 is provided adjacent its topand bottom bottom edges with parallel recesses 181 adapted to receive upper.
  • Pads 180 and 182 have inwardly. facing surfaces 184 and 186, which are inclined for cooperative engagement, respectively, with wear plates 177 on surfaces 176 and 178 when the wrapper roll assembly is in assembled relationship with the carriage. Accordingly, the planes of pad surfaces 184 and 186 converge in the direction from sidewall of the frame toward sidewall 18 thereof, and in the direction toward the mandrel axis.
  • the tapered surface of plate 57 define projecting guides and the tapered surfaces of pads and 182 define recessed guideways facilitating sliding engagement of the wrapper roll assembly relative to the carriage.
  • Bronze wear plates 188 and hardened steel linears 190 may be provided on plates 57 and 179, respectively, to enhance the sliding engagement therebetween during assembly and a tight fit therebetween upon completion of the assembly.
  • the cooperative tapers on plate 57 and carriage pads 180 and 182 provide for wrapper roll assembly 14 to be withdrawn from the coiling machine in a horizontal direction from side 20 of frame 10.
  • the tapered guides cooperate to support the wrapper roll assembly against displacement vertically relative to the carriage and in a direction from the carriage toward the mandrel.
  • the tapers are symmetrical with respect to a horizontal center line therebetween as this relationship enables interchanging the wrapper roll assemblies with respect to the carriages. It will be appreciated, however, that the desired sliding and interengaging relationship can be achieved with cooperable recessed guideways and projecting guides other than those illustrated and described herein, and that such recessed guideways can be provided on the supporting head and the projecting guides on the carriage. Many structural arrangements and modifications will be apparent to those skilled in the art.
  • end wall 149 of carriage 16 includes a flange portion 196 and the adjacent side of support head 30 of the wrapper roll assembly is provided with an opening 194 in wrapper roll arm 58 and a recess 195 in plate 57.
  • Flange 196 is provided with a recess 198 adapted to receive the shank of a pivotal lock bolt 200.
  • bolt 200 is'disposed in recess 195 and supported for pivotal movement relative to the head 30 such as by a pivot pin 202 extending through the bolt.
  • a spring biased finger 204 is supported by head 30 and is biased toward the pivoted end of bolt 200,'which pivoted end is provided with a pair of spaced apart recesses 206 and 208.
  • the outer end of bolt 200 is threaded to receive a nut 210.
