Description

  

   <EMI ID = 1.1>

  
The present addition relates to an improvement to the process and to the machine for making tear-off closures,

  
 <EMI ID = 2.1>

  
This improvement particularly concerns positions

  
 <EMI ID = 3.1>

  
on container closure and stacking finished closures.

  
In the machine described in the main patent, the pressing was controlled by angled levers, by means of eccentrics and a chain drive. The finished parts were lifted by means of helical elements rotating in opposite directions on the threads of which the parts came to rest. The elements

  
 <EMI ID = 4.1>

  
operation of the device is satisfactory, its implementation is not

  
 <EMI ID = 5.1> <EMI ID = 6.1>

  
According to the present improvement, the finished parts are lifted and then stacked by means of a very

  
 <EMI ID = 7.1>

  
formed. The aforementioned plate is actuated by a vertical rod whose reciprocating movement results from the positive re-engagement of a transverse element in an eccentric groove.

  
The same principle also applies to the movement which

  
 <EMI ID = 8.1>

  
cleaver,

  
 <EMI ID = 9.1> <EMI ID = 10.1>

  
In the drawings and, in particular, in FIG. 3, we

  
 <EMI ID = 11.1>

  
actuates a crank 7 fixed to the shaft 8. The shaft 8 carries two rockers 9 '(see also fig. 1) on the end of which few.-

  
 <EMI ID = 12.1> <EMI ID = 13.1>

  
elements of a transverse element 12 to which the ends are fixed

  
 <EMI ID = 14.1>

  
 <EMI ID = 15.1>

  
 <EMI ID = 16.1>

  
goes from shaft 8, the ends of connecting rods 10 and 11 thus being

  
 <EMI ID = 17.1>

  
in this way the desired compression effect on the workpiece.

  
 <EMI ID = 18.1>

  
and 11 additional, so as to cause similar movements;

china, the assembly being actuated by an eccentric and a crank

  
 <EMI ID = 20.1>

  
 <EMI ID = 21.1>

  
 <EMI ID = 22.1>

  
The plates 20 carry the finished parts. Due to the rotation of-.

  
the shaft 15 the plates 20 are lifted and they bring the finished pieces between the projections 22, which are therefore spaced apart.

  
. Then, during the return stroke of the plates 20, the protrusions <EMI ID = 23.1>

  
piece which they carry and, consequently, the stack of superimposed pieces. The projections 22 are shaped as angled levers to each

in its closed position "

  
 <EMI ID = 25.1>

  
 <EMI ID = 26.1> high, these parts having approximately the shape of a disc.

  
 <EMI ID = 27.1>

  
 <EMI ID = 28.1>

  
can provide construction variants of this device without

  
depart from the scope of the invention.

  
 <EMI ID = 29.1>

  
 <EMI ID = 30.1>

  
the lifting of a transverse element integral with the plates on

  
which rest the pieces, this lifting being obtained at

  
way of eccentrics.

 

Claims (1)

2.- Device according to claim 1, characterized <EMI ID = 31.1> reciprocating rotation of a shaft carrying balances which cause quent, with the intervention of a connecting rod, the reciprocating vertical of the cross member. 3.- Device according to claim, 2, characterized in that the aforementioned shaft is provided, at one of its ends,. : of a crank engaging via a roller in a radial groove of the eccentric. <EMI ID = 32.1> in that ,, in the stacking station, the movement imprinted in the summer-. transverse is directly by means of two eccentrics mounted on a continuously moving shaft. <EMI ID = 33.1> in that the transverse element is provided at its ends with <EMI ID = 34.1> next to the eccentrics. 6.- Device according to claims 4 and 5, charac- <EMI ID = 35.1> <EMI ID = 36.1> and meet, during their upward movement, elastic projections which move apart as the plate passes and come closer when the plate descends, these projections each hold the last part received by a tooth and, consequently , the stack of the various coins received. <EMI ID = 37.1> ized in that the movement of the aforementioned two shafts, arranged horizontally below the plane of the machine, is communicated to them by the same lateral vertical shaft. <EMI ID = 38.1> risé.en that the elastic protrusions are in the form of angled levers whose main vertical arm carries the tooth holding the workpiece, their shorter arm being constantly pulled to a rest position by a return spring. 10.- Device according to claim 9, characterized in that the protrusions are carried by blocks each placed between two of the four uprights of the stacking cages. 11.- Device for controlling the pressing movements <EMI ID = 39.1> <EMI ID = 40.1> -represented in the accompanying drawings.
