Description

The present invention relates to a method and an

  to supply packaging machines in

  preformed cases of tubular shape, folded and flattened.

  These preformed tubular shape packaging cases

  folded and flattened, are obtained, as it is

  naked, and having cardboard sheets in each of which

  the, following transverse and longitudinal lines or bands

  nales, several flat blanks are cut together by rupture bridges and equipped with panels, lips or panels for the assembly in tubular form of conditioning and the

  closing the cases at the opposite ends; then, we

  leaves from individual flat blanks

  right of the aforementioned break bridges, with a view to their

  on pallets in the form of overlapping layers with

  of flat support elements according to multiple batteries

  tiples.juxtaposed both transversely and longitudinally.

  These stacks of flat blanks are then normally

  by manual operation in a well or hopper of a-

  below which these drafts are taken from

  tomatically and successively to power the machine that

  shaping them to give them the shape

  bent, folded and flattened, in which these blanks are

  usually made to form batteries or

  quets in boxes to be delivered to users for

  to condense certain products.

  Even in the field of packaging or packaging

  of pharmaceutical products and the like, it is known to use this kind of cases or boxes preformed, shaped

  tubular, folded and flattened, which is called in the com-

  -2- "knockdown" cartons, which, also because of their ease of sampling,

  are distributed to packaging machines in the pre-

  lifting one-by-one under a short vertical magazine or hopper in which we add manually and as stacks

  while ensuring, during the feeding phase, that

  individual operation, the so-called deployment operation

  hold the tubular shape that allows to introduce the product

  to be packaged in the box, followed by the operation.

  at opposite ends of it.

  Due to the rapid increase in production rates

  the number of products packaged in the unit of time), to which these packaging machines have come, US-A-3 655 072 proposes to ensure

  by an automatic refueling order of the short magazine

  vertical sin supra in preformed cases of tubular shape, folded and flattened, using a large capacity magazine in which the cases intended to ensure this supply are

  arranged so as to form a long, sensitive file

  horizontally in order to transfer them under control "possibly

tail ", that is to say by gravity.

  As is apparent from this US patent, the adoption of such a large reserve, as conceived and arranged to supply the short vertical magazine referred to above, as is due, does not completely eliminate manual work; it only reduces the frequency or frequency

refueling the machine.

  The main object of the present invention, on the other hand,

  is to completely eliminate this intervention from manual labor.

  nuel in the refueling of a short vertical magazine in which the preformed cases, tubular, folded and flattened

  are taken individually to feed as and when

  on the packaging machines.

  Another object of the present invention consists in

  formity with the purpose stated above, to provide a method for refueling the short vertical store without solution

  continuity and in such a way that

kills by automatic means.

  Furthermore, the purpose of the invention is to enable the

  -3 installation of an installation for the purpose stated above, in

  exploiting for this the notches which form the parts of

  appearance in the tubular form of the cases and closure of

these latter.

  Finally, the invention aims, always in accordance with the aims stated above, to allow the realization

  such an installation through the use of automatic means

  ticks which can in turn be designed indifferently for the execution of an intermittent and / or continuous movement of a

  particularly simple way and ensuring a productive

  in the unit of time for a relatively low cost, especially considering the results that can be

  get in practice through these automatic means.

  These different goals, as well as others that are

  complementary, are achieved through the process and installation

  feeding according to the invention of

  packaging in preformed cases of tubular form, folded and flattened, these cases comprising assembly faces defined by cutting for their realization in tubular form and

  for closing these cases at their opposite ends ,.

  the method being characterized in that the cases, at the exit of the machine which ensures their tubular shaping, folded and flattened, are arranged transversely of edge in trays provided with lateral retaining walls whose height is calculated to not cover at least two opposite longitudinal notches defining the faces

  above mentioned, by the fact that the trays thus replaced

  folds are successively directed to the short vertical magazine

  corresponding cal of said packaging machines through tracks provided with fixed guide rails which engage in said longitudinally opposite slots, and that said trays are gradually disengaged or lowered by

  compared to the corresponding preformed cases, tubular in shape

  folded and flattened, leaving these cases slip into

  suspension on the fixed guide rails in order to be succes-

  pushed, under control, out of the successive trays, to and inside said vertical short magazine, while

  the trays thus emptied are directed to an unloading station

payment and reception.

  Other features and advantages of the installation according to the present invention will become more apparent during

  of the detailed description that follows and relates to a mode

  preferred embodiment of the invention, given by way of non-limiting example and with reference to the accompanying drawing, in which; FIGURES 1, 2 and 3 show three different types of preformed packaging cases, in their tubular form,

  folded and flattened for use in

  tioning; FIGURES 4 and 5 show the following kinds of cases

  Figures 1 and 3 in their prior placement in

  for their individual feeding in the machinery.

  and in plan, on an enlarged scale, the power plant

  according to the method of the invention, and FIGURES 10 and 11 show, still in elevation and plan, but in more detail, the power supply

Figures 8 and 9.

  As indicated above, FIGS. 1 to 3 show, by way of example, three types of preformed packaging cases in their tubular, folded and flattened shape,

  intended for use in packaging machines.

  The case shown in Figure 1, designated 1, comprises flaps, lips or closure panels 2, 2a and 3, 3a symmetrical, defined by longitudinal notches and aligned 4; the case shown in Figure 2, designated 5, comprises flaps, lips or closure panels 6, 6a and 7 asymmetric, defined by notches 8 also aligned in the longitudinal direction, and -5- and finally the case 9, shown 3, comprises flaps or flaps, lips or closure panels 10, 10a, 11, 11a,

  also asymmetrical but defined by notches 12

  aligned in the longitudinal direction for the different

  opposite side wall (or coat) of the case

well said.

  The method according to the present invention for delivering these packaging cases, provided with flaps, lips and panels

  assembled and closed, and preformed, so as to

  storing a tubular shape, folded and flattened, to packaging machines, provides for their realization, at the exit of the machine which serves to give them this tubular shape, folded and flattened, to deposit these preformed cases in cardboard trays 13 and 14, in a transverse and edge position, these trays being provided with lateral retaining walls whose height is calculated so as not to cover at least two longitudinally opposite notches 4, 12 (see FIG.

  Figures 4 and 5), which define the remaining flaps

  closing poles 2, 2a; 3, 3a and 10, loa; 11, lla.

  The trays, thus filled; always according to the

  tion considered, in a manner which will be described in detail later, by the machine which ensures the packaging of the product in these cases, this displacement being effected by means of rails fixed guides that engage in the notches

longitudinally opposite.

  During this journey and up to the short vertical store, the trays are "loosened" or released progressively from below by the preformed cases, tubular, folded and flattened, leaving these cases slide in suspension on

  the fixed guide rails, in order to be pushed successively

  on the order, out of successive trays, to and inside the short vertical magazine, while the trays thus emptied are directed to a unloading station and

reception.

  This method of feeding the machines to be packaged

  products in these preformed cases, tubular in shape,

  folded and flattened, is implemented through a device as-

  partner in one of these packaging machines.

  In Figures 6 and 7, there is shown by way of example

  a machine of this type, combined with a machine for

  blisters 15, which is manufactured and marketed

  The blister-making machine comprises in substance (see Figure 6), from upstream to downstream by

  relation to the direction of movement of a strip being processed.

  In order to obtain cells or cells, a compartment A which carries out stamping of the above-mentioned cell or cell strip intended to contain the different products. To be packaged in this type of packaging, a compartment B which

  deposits in these cells or cells the products with

  ner, a compartment C o is hermetically sealed cells or cells each containing one of the aforementioned products to be conditioned, by the superposition, on the same band thus shaped and moved, a second band that can be solder to the first, and finally a compartment D for the separation of the complex strip thus obtained so as to form individual blisters that are conditioned

then in cases.

  In combination with the machine 15 manufacturing

  blisters, for example the aforementioned machine IMA C 65 (see also

  Figures 6 and 7) or by a machine 16 to make the

  cases (see Figures 10 and 11) of a type known in the

  under the trademark ZANASI K 400, arranged downstream of a

  China to manufacture blisters in the IMA C 60 version (no

  shown), there is provision for equipment designated in its

  appears by reference number 17 (see in particular the

  Figures 8 and 9) for dispensing packaging cases

  preformed, tubular, folded and flattened, in

  trays 13, 14 according to the method of the present invention.

  tion. These trays 13, 14 which contain cut and grouped cases, preformed, of tubular shape, folded and flattened 1 or 5, 9, are directed successively, thanks to an endless conveyor system 18, 19 (see in particular the 7 and 11), towards a transfer station S on two fixed horizontal guiding and support rails 20 (see FIG. 9) using two endless belts 21 provided with thrust elements 22 (FIG. see in particular Figures 8

and 9).

  During the forward movement of the trays pushed by the thrust members 22 of the two endless belts 21, the notches 4, 8 and 12 of the respective holsters are engaged by fixed guide elements 23 (see in particular Figure 8) and when the trays have reached a station R, a suction arm, actuated by a kinematic device with fluid control under pressure, designated as a whole

  by the reference numeral 25, Figure 8, discharges the

  quet corresponding cases by depositing them on a conveyor with two parallel and endless conveyor belts 26, so that these cases remain suspended from the fixed elements of

  guidance 23 (see again Figure 8).

  The cases thus released and suspended to the fixed guiding elements 23 are urged forward by the trays

  successive stages until they are above a transpor-

  27 which, on order, insures the insertion in the magazine

  short and vertical sin supra, designated at 28 in Figures 6 to 11, while the empty trays deposited on the conveyor

  26, are directed to an unloading and receiving station.

  Of course, the description here referring to

  the accompanying drawings relate only to exemplary embodiments to which many modifications and variations may be made by those skilled in the art.

  without however departing from the basic principles of the invention.
