Definitions

  • the invention relates to a machine for flanging and pulling cylindrical can bodies on both sides according to the preamble of claim 1.
  • the aforementioned machines are known (prospectus Lanico "automatic flanging and drawing-in machine BEA 6-325"), which are designed as fully automatic machines and in which the can bodies pass through the machine in a horizontal position.
  • Such machines have proven extremely useful in practice for processing cylindrical can bodies with welded longitudinal seams, as are used in particular for aerosol or beverage cans.
  • the invention has for its object to develop a machine of the type mentioned in the introduction so that it is suitable both for processing relatively soft and hard sheets.
  • each swashplate is assigned two flanging and drawing-in rollers arranged on parallel axes and held so that they are each at the same time attack the can body to be treated and gradually deform it in the direction of its rotation.
  • can bodies can be processed from the above-mentioned sheets, and indeed within processing times as they are for previously workable sheets are necessary, but without cracking appearing in the hard or double-reduced sheets.
  • the two flanging and pulling-in rollers should expediently be arranged as closely as possible one behind the other on the circumference of the can body, as seen in the direction of rotation of the can body, so that the pre-deformation caused by one roller is subjected to the action of the second roller for subsequent deformation after a short distance.
  • the two flanging and drawing-in rollers assigned to each swash plate are arranged together at the free end of the swivel lever and at least one of the rolls is held adjustable in and against the swash plate with respect to the other roll. Due to the adjustable mounting of the rollers to each other, the degree between the respective pre- and post-deformation can be adjusted during each rotation of the can body.
  • roller arranged further outward at the free end of the swivel arm is held in the swivel arm so as to be pivotable about the axis of rotation of the other roller. In this way, a sensitive adjustment of the one roller relative to the other can be carried out.
  • a further expedient embodiment results from the fact that the roller, which is arranged further outward at the free end of the swivel arm, is narrower than the other roller, at least in the peripheral region with which it engages in the can body.
  • the fuselage rim Due to the smaller and / or narrower roller in diameter at the free end of the swivel arm, the fuselage rim is deformed before it is subsequently exposed to the larger roller.
  • the hull material springs back after being deformed by the first roller, but is largely compensated for by the second roller.
  • the drawing shows an embodiment of the invention.
  • the machines shown in Figures 1 to 3 consist of two drive units 1 and 2, which are held on a base and controlled by a synchronizing device so that they drive the central shaft 3 together.
  • the guide disks 4 have recesses for the tools (not shown in FIGS. 1 to 3) for pulling in and flanging the ends of the can bodies.
  • FIGS. 1 and 2 The machine shown in FIGS. 1 and 2 is equipped according to FIG. 3 with six planetary stations 5, to which the can bodies 7 are fed via a feed trough 6.
  • an additional supply channel 6 ⁇ is provided in order to ensure the continuous operation of the machine shown, if possible.
  • FIGS. 4 to 6 The structure of the flanging tools of the individual stations 5 and their mode of operation can be seen from FIGS. 4 to 6.
  • FIGS. 4 to 6 show only one of the units 1 and 2 in partial section, since the other drive unit with tools held in it has the same structure as the unit shown in FIG. 5.
  • the flanging and retracting head 9 is connected to a spindle 11 which can be driven in rotation.
  • the spindle 11 is in turn held or supported in a thrust sleeve 12.
  • feed rollers 13 are connected in a rotationally secure manner, which engage in a groove 14 of a ring part 16 held stationary in the housing 15.
  • a guide roller 17 connected to the thrust sleeve 12 is firmly connected, which in turn interacts on a guide track 18 rotating with the central shaft 3.
  • the thrust sleeve 12 is held in an annular bearing part 19 connected to the central shaft 3.
  • the structure of the flanging and retracting head 9 is shown in detail in the enlarged illustration in FIG. 6.
  • a counter disc 20 cooperating with the flanging or retracting roller is secured against rotation.
  • a swash ring 21 is supported on the counter disc 20, which is held with little play between the counter disc 20 and a sleeve 22 which rotates with the spindle 11.
  • the swash ring 21 acts axially on the spindle 11 against a spring 23 slidably held cone part 24 together.
  • An abutment bell 25 in the form of a ring component is also held on the sleeve 22.
  • the respective end of the can body 7 is pressed and deformed by the flanging roller to be described against the swash plate 21, the opening edge of the can body interacting with the abutment bell 25, which holds the can body freely between the two flanging and retracting heads 8 and 9 stabilized in its position.
  • the swash plate 21 is displaced radially under the action of the flanging roller and in turn causes an axial displacement of the conical part 24 under the pressure of the spring 23.
  • the swash plate 21 is displaced so far that in the area between the counter plate 20 and the sleeve 21 the crimped edge is created.
  • Each crimping and retracting head 8 or 9 is assigned a pivot arm 26 held in the annular bearing part 19, which can be connected in a rotationally secure manner to a pivot axis 27, which in turn interacts with a control cam 31 via a cantilever arm 28 and cam rollers 29 and 30 rotatably held thereon .
  • the control curve 31 is held in the ring-shaped component 16 in a rotationally secure manner.
  • Flaring and retracting rollers 32 and 33 are provided at the free end of the swivel arm 26, two are arranged on parallel axes according to the invention Flaring and retracting rollers 32 and 33 are provided.
  • the flanging and drawing-in roller 33 is held pivotably with respect to the flanging and drawing-in roller 32.
  • the flanging and drawing-in roller 33 is mounted in a cantilever arm 34, which in turn is connected to the swivel arm 26 in an articulated manner, but can be locked in any angular position.
  • FIG. 5 shows the parallel course of the axes of rotation 32a and 33a of the flanging and drawing-in rollers particularly clearly.
  • Fig. 5 also shows the locking screw 35 for the cantilever arm 34.
  • the roller 33 arranged further outward on the swivel arm 26 is kept smaller in diameter in the exemplary embodiment than the roller 32. It also has a smaller thickness than the roller 32.
  • rollers 32 and 33 act simultaneously on the respective can body 7, and that when the rotational movement of the can body 7 is shown in the direction of movement of the can body 7, first the narrower and smaller roller 33 and then the larger and larger in diameter also wider roller 32 engages in the can body.
  • the configuration of the flanging and retracting heads 8 and 9 with associated actuating devices described for a station and the flanging and retracting rollers 32 and 33 interacting therewith with the associated swivel arm 26 are configured identically in all stations of the machine shown.
