Definitions

  • This invention relates to a device for automatically forming and applying metal delivery mouths to packaging containers for flowable products, in particular cardboard containers for powders.
  • a device of this type is described for example in Italian patent 828,966.
  • the delivery mouths are formed from a metal strip and fed intermittently to a device, the purpose of which is to apply them to the boxes.
  • Said applicator device is formed structurally from a hammer and an anvil.
  • the hammer comprises a cavity for receiving the formed delivery mouth, and is arranged to be moved, in synchronism with the anvil, into a position corresponding with the container in order to carry out the application of said mouth.
  • Machines of the type described in Italian patent 828,966 are large rotary machines of high productivity, and comprise a turntable carrying a plurality of said applicator devices each cable of successively applying the delivery mouths to the containers, which are continuously fed in an upright position by a suitable conveyor.
  • a machine of lower productivity able to be coupled to packaging machines into which the empty containers are conveyed in a lying position by spindles which move stepwise.
  • the object of the present invention is to satisfy the aforesaid need, and for this purpose the invention provides a device for automatically forming and applying metal delivery mouths to packaging containers for flowable products, of the type in which each mouth is formed from a metal strip by a forming unit and is fed to a complementary seat in an arm provided with a hammer which is arranged to apply the mouth to a respective container, characterised in that said arm is movable alternately between a vertical position in which the mouth is received in said seat from said forming unit by gravity, and a horizontal position in which said mouth is applied to a container, there being provided a positioning unit arranged to correctly locate the mouth in the seat, and sequential operating means for said unit and said arm.
  • the device according to the invention is formed from a frame 10 carrying a forming unit indicated diagrammatically by 11 and of known type, arranged to form delivery mouths 12 from a metal strip 13.
  • the formed mouths 12 are fed one at a time to an underlying applicator device, indicated generally by 14, which offers them up to a cardboard container 15 and applies them thereto.
  • the applicator device 14 comprises an L-shaped arm 16 which swivels about 17 between the vertical position shown in Figure 3 and the horizontal position shown in Figure 5.
  • a percussion head 19 commonly known as a hammer, slides on suitable guides 18.
  • said head 19 is articulated to one end of a bell crank lever 20 pivoted at 21 to the arm 16, and maintained in the position of Figure 2 by a spring 8.
  • Said bell crank lever is oscillated by the rod 22 of a cylinder 23 fixed to the machine frame.
  • a positioning unit indicated generally by 24 cooperates with the described applicator device 14.
  • Said unit 24 is composed of a blade 25 and a pusher 26 which are rigid with each other and are carried by a slide 27 slidable on guides 28.
  • a locking device also cooperates with the applicator device, and consists of the rod 29 of a cylinder 30, said rod becoming inserted into two bores 31 of the arm 16, so as to lock it exactly and securely in said vertical and horizontal positions.
  • the containers 15 are mounted in a -lying position on spindles 32 of a packaging machine (not shown) movable stepwise.
  • said spindles 32 carry each container 15 against a counter-member 33 which is movable vertically in a guide block 34 between the lowered position of Figure 3 and the raised position of Figure 5.
  • the oscillation of the arm 16 about 17, the horizontal movement of the positioning unit 24 and the vertical movement of the counter-member 33 are controlled in the correct sequence by means of a single control system.
  • This control system can for example comprise a drive shaft 35 with which there are rigid two plates 36 in which cam seats 37 are formed in order to provide, by means of lever systems, the abutting movement of the counter-member 33 and the oscillation of the arm 16 about 17 respectively.
  • said shaft 35 drives a second shaft 39 carrying a third plate 36 comprising a cam seat 37 which operates the positioning unit 24 by means of lever systems.
  • the delivery mouths 12, formed by the forming unit 11, are made to fall one at a time into the underlying applicator device 14. More specifically, the mouth 12 falls into the cavity 9 ( Figure 2) when the percussion head 19 is in its rest position, in which it is maintained by the action of the spring 8 on the bell crank lever 20.
  • the positioning unit 24 operated by the combination of the plate 36 with cam seat 37 driven by the shaft 39 and the respective lever systems, moves by virtue of the sliding of the slide 27 on the guides 28 until the blade 25 and the pusher 26, which is provided with elastic means, correctly position the mouth 12 against the percussion head 29 ( Figure 4).
  • the cylinder 23 is operated so that its rod 22 engages against the lever 20 pivoted at 21, to cause the percussion head 19 to slide on the guides 18.
  • the counter-member 33 is lowered inside the guide block 34, and the packaging machine rotates its spindle 32, which carries the container 15 to which the mouth 12 has been applied.
  • the rod 29 of the cylinder 30 withdraws from the second bore 31 and enables the arm 16 to return to the vertical position under the forming unit 11, where it is locked by the engagement of the rod 29 of the cylinder 30 in the first bore 31 ( Figure 2).
