Definitions

  • the present invention relates to machines for rotary cutting of cardboard blanks of the type described in EP-A-0 493 229, which serves as a basis for the preamble of claim 1 and concerns more particularly improvements to the devices ensuring the shelling of the cut blanks.
  • one of the cutting cylinders usually the cylinder counterpart, has sharp elements, such as spikes, which cross the shell, so that at during the rotation, the latter is driven by the pins which ensures its separation from the rest of the blank. Combs between the teeth through which the pins pass then ensure the extraction of the preserved hulls by the pins.
  • This separation can also be achieved by shelling means distinct from the cutting means which consist of a specific shelling module which is arranged downstream of the cutting means.
  • this shelling module consists of two respective series of discs arranged opposite one above the other, between which the cut blank.
  • One of this series of discs, usually the lower discs, is provided with spikes which, as before, pass through the shell to enter holes provided in the cylinder cutting, so that during rotation the shell is separated from the rest of the cut blank and driven by the pins, as described above.
  • the object of the present invention is to remedy these disadvantages by proposing a device for shelling with pins, the constitution is such that it is no longer necessary, to avoid jamming, that the front edge of the combs is fine and that it is placed near the cylinder or the disk.
  • the subject of the present invention is therefore a device according to claim 1.
  • the rotary elements consist of discs and areas sharp gripping elements are formed from of planar elements which are fixed on the base faces of them. These gripping elements can also be fixed against a side face of a shoulder circular discs.
  • the gripping elements consist of a threaded cylindrical part which is surmounted by a flat itself surmounted by a point constituting the area sharp and it includes a fixing lock nut, the threaded part intended to be screwed into a hole threaded of the rotary element and to be locked on it in a position such that the base of the point is at a distance from the external surface of the cylinder equal to at minus once the thickness of the blank.
  • the part of the gripping element included between the base and the base of the sharp area forms a flat whose width, (or dimension in the direction of the axis of rotation of the gripping elements), is equal to that of the sharp area.
  • the device according to the present invention thus allows the hull to be removed from the rotary element carrying the gripping elements, which facilitates the introduction of the comb between these two elements. In these conditions on the one hand it facilitates the realization of means of separating the shell and on the other hand avoids jams.
  • FIGS 1a and 1b are schematic views of two shelling means implemented according to the prior art.
  • Figure 1c is a partial plan view of a comb.
  • Figure 1d is a sectional view of the comb shown in Figure 1c along the line Id-Id of it.
  • Figure 2 is a schematic front view of a separate shelling device.
  • Figure 3 is a partial side view at more large scale of the shelling device shown in figure 2.
  • Figure 4 is a sectional view along the line IV-IV of the device shown in Figure 3.
  • Figure 5 is a sectional side view partial of a device according to the invention, in progress extraction by combs, of a maintained shell by gripping elements.
  • Figure 6 is a front view of two cylinders one of which is provided with removable gripping elements and adjustable according to a second form of implementation of the invention.
  • Figure 7 is a radial sectional view partial on a larger scale of the second mode of implementation work shown in Figure 6.
  • Figure 7a is a top view of the device shown in Figure 7, the upper comb being shown in dotted lines.
  • FIG. 7b is a view in radial section of the device shown in Figure 7 along the line VIIb-VIIb thereof.
  • FIG. 1a shows a device for rotary blank for cardboard blanks which includes essentially two cylinders, namely a cylinder upper 1, called cutting cylinder, i.e. a cylinder which includes the threads ensuring the cutting of the cardboard, and a lower cylinder 3, said cylinder counterpart, which is smooth, between which is entrained a blank of cardboard to cut 5.
  • this device is provided with integrated shelling means. These means consist of gripping elements, such as spikes 7, which protrude from the external surface of the counterpart cylinder 3, and of cavities complementary 9 provided in the cutting cylinder 1, which are intended to accommodate the spikes 7.
  • the device also includes combs 11 (FIGS. 1c and 1d) which have longitudinal slots 13 which are intended for the passage of points 7.
  • the blank to be cut 5 is driven in the direction of arrow F between the two cylinders 1 and 3 which perform the cutting operation. Immediately this performed, the tips 7 enter the shell 5a and drag it down, while the rest 5b cut blank continues on. Comb 11 is arranged in such a way that it extracts the peel of the tips 7.
  • the present invention will be described below in the part of a separate shelling device but it could of course also be implemented in any type of hulling and especially in integrated cutting devices.
  • the separate shelling device shown schematically in Figures 2 to 4 is essentially consisting of a frame 12 which supports a lower shaft 14 and an upper shaft 14 '. These trees support respective lower 16 and upper 16 'discs, which provide training between them of a cut blank 5 from cutting means not shown.
  • the lower discs 16, as shown in the Figures 3 and 4 are hollowed out on each of their faces of a circular groove 21, so as to form a circular shoulder 18. Opposite lateral flanks 20 of this shoulder 18 serve as support for elements of gripping 22 provided with sharp parts 23 intended for enter shell 5a and train it so to separate it from the rest 5b of the blank 5.
  • the gripping elements 22 consist of a steel plate which is applied to a lateral blank 20 of the circular shoulder 18 by a screw 28 which passes through a light in an arc of a circle 26 of the plate, light centered on the axis of the rotary element 16, to be screwed into threaded holes 30 of the sidewall 20, with the interposition of a tightening washer 32.
  • the lower part of the plate 22 is in the form of an inverted V so that it is supported in two points on the base 25 of the circular groove 21. In this position, as shown in FIGS. 3 and 4, the upper part of the plate, or base 27, protrudes from the external face of the circular shoulder 18 d ' a value d of the order of a few millimeters, for example 3 millimeters.
  • the base 27 is extended outwards by the sharp part 23 which is in the form of a knife, the faces of which are sharpened in order to improve its penetration into the shell 5a.
  • the threaded holes 30 are provided with angular spacings such that, taking into account the angular difference of the window 26, it is possible to angularly position the sharp part 23 at any point on the periphery of the disc 16.
  • the sharp part 23 will preferably be arranged on one side of the base which will allow, by turning face to face of the wafer to obtain two angular positioning zones of the sharp part 23.
  • the device comprises combs 11 which are arranged near the external periphery of the circular shoulder 18 so that the slots 13 with which they are provided allow the passage of the sharp parts 23 of the plates 22 and of their base 27.
  • the width has slots 13 of the combs 11 will preferably be as close as possible to the thickness of the plates or gripping elements 22.
  • the value whose base exceeds the external face of the discs 16 may vary depending on the different types of application. It will generally greater than the thickness of the blank 5.
  • the gripping elements 22 may be made up of any device other than platelets.
  • each gripping element 22 ' is formed of a threaded part 36 which has at its part upper a flat 38 which is itself surmounted by a cylindrical element 37 of the same diameter as the thickness of the flat and which ends at its upper part by a point 40.
  • the threaded part 36 is screwed into the threaded hole 34 so that the base 27 'is located at the desired distance d from the external surface of the cylinder 31 and that the flat 38 is oriented parallel to the axis of the cylinder 31.
  • the threaded part 36 is held in position by a lock nut 39.
  • the upper face 27 ' of the flat 38 thus constitutes a base which is intended to receive the underside of the shell 5a and to thus moving it away from the external surface of the cylinder, thus allowing the teeth 13 of a comb 11 in passing on either side of flat 38 closest to it as shown in Figure 7a to release easily the shell of the sharp element constituted by the tip 40 without risking jamming.
