Description

Charger for feeding a horizontal magazine of a machine

Treatment of

  plate products, and method of use.

  The present invention relates to a charger for the supply of

  a horizontal magazine of a plate product processing machine, such as for example a packaging machine and

  packaging of pharmaceutical products.

  On a packaging machine packaging (cases, easels or other), are brought together various elements which, together and arranged between them, form a whole at the output of the machine, the finished product being intended

for sale and use.

  Thus, on a machine of this type, a supply of the product to be packaged is generally provided mechanically. It is the same with the packaging, but the supply of it is however carried out, at first, by a manual operation. This manual operation is constituted by the transfer from the delivery box to the store of the packaging machine. This store is a reserve of packaging that are from this station routed mechanically on the circuit of the machine. The invention relates to a loader intended to ensure the connection between the delivery box packaging and the store of the machine, in other words the transfer mentioned above. Generally in the case of materials known on the market, one or more people draw from a box of packaging, whether they are folding cases, flat blanks, trestles or others, and by handles have these

  packaging in the machine shop. The store is mechanically emptying

  the faster the packaging machine is fast.

  On these modern machines, the production rates have become very fast, the operation of transfer and supply

  manual packaging has become very restrictive. Staff do not

  In many cases, this does not guarantee the proper supply, or this procurement operation mobilizes one or more full-time staff for this task. Production is then penalized. The object of the invention is to facilitate this transfer and supply operation by providing, with the aid of a removable pre-packaging called "charger", in the machine magazine a significant quantity

  packaging in one go, avoiding multiple manual operations.

  It can therefore flow with the reserve thus constituted several minutes of

  production, giving the person in charge of

  to better organize or to engage in other tasks around or on the machine in the meantime.

  There are currently two main types of

  provisioning of plate products processing machines: - so-called "vertical" magazines, where the blanks are stacked on top of each other in vertical guides and descend by gravity as the mechanical system picks them up at the base one by one. For

  vertical magazines, several types of magazine loaders are known.

  provisioning. They are generally constituted by closed sleeves at both ends, which are reversed in the vertical magazine, after removing one of the end fillings and holding the blanks during the establishment. Then simply remove the sheath by pulling it by the

  top, and the blanks remain in the store.

  - so-called "horizontal" stores, where the packaging is arranged

  on column singing, one behind the other, and advance horizontally

  to the gripping system of the driven machine by a belt.

  You can not easily use a model loader for such stores

  known, built to power a vertical store.

  The subject of the invention is therefore a closed sheath-type magazine containing a certain number of blanks, and intended to enable a horizontal magazine to be fed with plates, such a magazine being

  characterized in that it is in the form of a parallelepiped box

  pèdique semi-rigid material whose upper face has a central longitudinal groove on a middle portion of its length, with pre-cutting lines connecting the four corners of the groove to the corresponding four corners of said upper face, and at least the front face comprises a central lower opening, with two pre-cutting lines connecting this opening to the two upper corners of said face.

  The invention will be better understood with the aid of the following description

  of an exemplary embodiment, with reference to the appended drawings in which:

  Figure 1 is a plan view of the charger of the invention,

  flattened out flat before assembly into a parallelepiped box, Figure 2 shows the loader of figure 1 being assembled around a pack of blanks on edge, Figure 3 shows the loader assembled and filled with the pack of blanks on edge Figure 4 shows the horizontal magazine feeding the machine using a horizontal column of edge blanks, Figure 5 shows the installation in the magazine of the loader of the invention, Figure 6 shows the Figure 7 shows the following operation of releasing the rear part of the loader, Figure 8 shows the beginning of the loader extraction phase, Figure 9 shows the current loader. extraction, Figure 10 is a perspective view of the horizontal magazine of the

  machine, with the feeder at the beginning of extraction phase.

  Figure I shows the charger of the invention, fully unfolded and laid flat before assembly. It is composed of a semirigid material packaging, such as cardboard, consisting of a flat blank I whose various constituent parts are as follows: a bottom plane 2, in the shape of a very elongated rectangle as shown, delimited by four folding lines 3, 4, 5, 6, - two transverse flaps 7, 8 extending the rectangle 2 beyond its longitudinal fold lines 3, 5 forming its long sides; each of these flaps 7, 8 is divided by longitudinal fold lines 9 and 10 into a first flap, respectively 11, 12, contiguous to the bottom plane 2, said lateral transverse flap, and a second outer flap, respectively 13, 14 , called upper transverse flap; according to the invention, the sum (2a) of the widths (a) of the two outer flaps 13, 14 is smaller than that I of the rectangular bottom plate 2; moreover, each upper transverse flap 13, 14 is provided, at each of its two longitudinal ends, with a transverse tab, respectively 15, 16, 17, 18, each separated from the central part of the upper transverse flap by a line of oblique pre-cutting, respectively 19, 20, 21, 22 joining as shown the associated end, respectively 23, 24, 25, 26, of the longitudinal fold line, respectively 9 and 10 delimiting the transverse flap greater than the starting point inside, respectively 27, 28, 29, 30 of the tab; finally, the overall transverse width b of each tab is equal, in the nonlimiting example considered, to half the width I of the rectangle 2, while noting that it could alternatively be less than this value or even greater than this, - two longitudinal flaps 31, 32 extending the rectangle 2 beyond its transverse fold lines 4, 6 forming its short sides; each of these flaps 31, 32 is divided by transverse fold lines 33, 34 into a first flap, respectively 35 and 36, contiguous to the bottom plane 2, said lateral longitudinal flap, and a second outer flap, respectively 37 and 38 , said upper longitudinal flap; the length h of each of the flaps 35 and 36 is equal to the width h of each of the flaps 11 and 12, and will define the height of the box forming the loader; as seen in the drawing, each flap 35 and 36 is pierced with a central rectangular opening 39, 40 and resting on the fold lines 4 and 6; on each of the flaps 35 and 36, two pre-cut lines 41, 42 and 43, 44 connect as shown the outer corners of each rectangle 39, 40 to those associated with the flaps 35 and 36; advantageously also, fold lines 45, 46 and 47, 48 are provided on flaps 37 and 38 symmetrically with respect to lines 33 and 34 respectively

  pre-cutting lines 41, 42 and 43, 44.

  In general, therefore, all the dimensions of the flaps and legs of the blank I are such that they allow the making by bending, then fixing by gluing or the like, from the blank 1, a parallelepiped box as shown in the figures 2 and 3 at which we

will refer now.

  As shown in FIG. 2, to produce from blank 1 a magazine filled with blanks 49 on edge, the blank column 49 is placed on edge on the bottom plane 2 of the box, then as indicated by the arrows f, the flaps 49 are folded firstly on the longitudinal flaps 31, 32 and, as indicated by the arrows F, the transverse flaps 7 and 8 are folded together. The loader of the invention shown in FIG. 3, which is fixed to prevent it from deviating with the help of two

pieces of tape 50.

  As seen in Figure 3, the charger of the invention is completely symmetrical with respect to its transverse median plane. As can be seen on its front part fully visible in FIG. 3, each of its ends shows the central lower opening 39 with the pre-cutting lines 41, 42 connecting this opening 39 to the two upper associated corners of the front face. . Furthermore, the magazine has on its upper face a central longitudinal groove 51 on a median portion of its length, with pre-cutting lines 19, 20, 21, 22 connecting the four corners of the groove 51 to the four corresponding corners of

the upper face.

  The method of using the charger of FIG. 3, that is to say the manner in which the blanks 49, which the charger contains, are described in FIGS.

Horizontal store of the machine.

  Figure 4 shows very schematically the horizontal magazine of an automatic cartoner for pharmaceuticals. It consists essentially of an endless belt 52 on which an operator comes to place cleats 53 for keeping on edge the blanks 54, placed horizontally against each other as shown to form a horizontal column 56 and continuous. On either side of the endless belt 52, the blanks 54 are guided in the magazine by two longitudinal plates 55 (see also in FIG. 10) forming lateral ribbons. The gripping device 54 plates one by one in the column 56 is shown

  schematically by a rotary cylinder 57 provided with suction cups 58.

  To transfer the magazine of the invention to the horizontal magazine

  In front of the machine, it is first determined, looking through one of the openings 39, where is the portion of the blanks to be presented downstream, and oriented the charger accordingly. It is indeed important that the cases 49, or others, are presented in the correct

meaning in the machine shop.

  Then, as shown in Figure 5, the charger is placed on endless belt 52, as close as possible to the tab 53, behind the column 56 already in place. As shown in FIG. 6, the fingers are then slid into the front opening 39, and one pulls upwards abruptly. This movement causes the four pre-cut lines 41, 42, 19, 21 to yield so that, as will be understood with reference to FIGS. 2 and 3, substantially all of the longitudinal front flap 31 is torn off, as well as the

two legs 15 and 17.

  As can be seen in FIG. 7, the blanks 49 at the front of the magazine then bear on the cleat 53, moreover

  still weakly supported by the two remaining tabs of the flap 31.

  By passing the fingers under the rear side of the upper central opening 51, and pulling sharply upwards as shown in FIG. 7, the two lines 20 and 22 are yielded, which makes it possible to disengage towards the rear flap 32, as seen in Figure 8. The side flaps 7 and 8 are held in vertical position by the two side guides 55 of the magazine. In these two stripping operations, the folds 45 to 48 come, forming a wedge, in aid of the cutting operation of the pre-cut lines 41 to 44. These folds are however optional, although advantageous. At the same time, as can be seen in FIG. 8, that the flap 32 is pulled backwards, the blank column is held with the other hand, advantageously pushing downstream with it, and, as seen in FIGS. 9 and 10, the magazine is pulled back by the flap 32 until it is completely withdrawn. Finally, another push and hold stop is placed behind the column of blanks 49, and the operation is completed. It is clearly seen in Figure 10 that the opening 51 is essential to allow the passage to the fingers now the blanks 49

  while the magazine is pulled backwards by the flap 32.
