Definitions

  • This invention relates to a system and a method of forming flattened boxes, in particular for containing disk records.
  • disk record packaging boxes intended for packaging disk records therein are required to possess high structural and aesthetic features, since they perform the dual function of attracting potential buyers of the disk records through the high quality of their appearance, and of protecting from shocks and incidental drops a-fragile and sometimes very expensive item, such as a disk record can be.
  • disk record packaging boxes must have some desirable features, such as resistance to crushing, thereby they can be stacked without trouble or incidentally put under some heavier object, and low cost, in order for the cost of the box not to affect appreciably the cost of the packaged product.
  • boxes of various types have been made and sold in the past, generally formed from some cardboard, and having their edges simply folded over and stapled together, or even secured together by means of adhesive tape or glues.
  • cardboard boxes are generally lined both on the inside and outside thereof.
  • the outer lining is finished with the application of a printed label identifying the record contained in the box and glued to the latter.
  • the task of the invention is to provide a thorough solution to the foregoing problems, by providing a system and method which can afford a fully autometeu production of boxes for containing records and the like.
  • the invention provides a system and method for the production of said boxes which also lend themselves to the partial utilization of manual labor, depending on circumstances and preference.
  • the invention provides a system as indicated, which can be operatively split in several separate and variously located parts, thereby allowing, in addition to the cited utilization of manual labor, an optimum layout of the various parts of the system within a manufacturing plant.
  • both the carton containing bottoms and covers are formed from flat quadrangular semi-rigid sheets peripherally die-cut to present along two opposed sides a first pair of lateral bands extending into tongues at both ends, and a second pair of lateral bands being arranged alternately with said first pair of lateral bands and having no tongues, the method comprising, according to the invention, the following steps:
  • the system according to the invention which implements the foregoing method is characterized in that it comprises an auxiliary processing line provided substantially with members for continuously entraining said flat die-cut sheets in a parallel direction to said first lateral bands with tongues, cementing members and ramp-like folding members adapted to cause said first lateral bands to adhere to themselves by acting with a - sweeping action on the moving sheets, and in that it comprises a main processing line having first entraining devices effective to translate said sheets, with said first bands being pre-folded, in a parallel direction to said second lateral bands, a cementing station provided with grid-like dispensing members and adapted to act on those faces of said sheets which will lay on the inside of the carton or case being formed, folding devices operative to position and secure said lateral bands together, and inserting means effective to cause a plate and said carton or case bottom to adhere and become secured together.
  • auxiliary processing line provided substantially with members for continuously entraining said flat die-cut sheets in a parallel direction to said first lateral bands with tongues, cementing members and
  • both the method and the system according to this invention are adapted for manufacturing flattened configuration boxes having substantially identical bottom bodies and lids, excepting for their dimensions and graphical representations.
  • Figure 2a in particular shows a bottom body 1 having a square profile (although it will be appreciated that other profiles may be preferred).
  • the body 1 of Figure 2a has a base or bottom 2 of large dimensions which is surrounded by sides 3 extending at 90° with the base 2.
  • Figures 3 and 3a illustrate a completed carton or case, also suitable for production with the method and system according to the invention throughout; in fact, both the bottom 1a and cover 1b can be formed from a single flexible sheet 4a ( Figure 3), which is die-cut substantially in the same manner as the sheet 4, the only difference being in the portion 4b interconnecting the bottom with the cover and essentially constituting the connective and rear side of both bodies 1a and 1b with the carton in the closed condition.
  • the pairs of lateral bands 5a and 7a are lined up with each other and identical to the bands 5 and 7 of Figure 2,thereby the complete carton 1a-1b can also be formed with the method and system of this invention, with the obvious exception of some suitable modifications in the number and dimensions of the cement-applying means and plate inserting means, which will be twice in number as those required to form a single bottom or single cover.
  • the containing body or bottom of a carton is formed, as mentioned hereinabove, from a semi-rigid sheet 4, as shown in Figure 2; it has first lateral bands 5 provided with end tabs 6, and second lateral bands 7 which alternate with the former and have no tabs.
  • the method according to the invention for forming the semi-rigid sheet 4 into the bottom 1 of Figure 2a comprises, as shown in Figure 1, a first step 8 wherein the first lateral bands 5 are folded, a second step 9 wherein the first bands 5 are positioned and the tabs folded, a third step 10 wherein the second lateral bands 7 are folded, and a final step 11 wherein the bands are set with the insertion of a shaped plate 12.
  • auxiliary steps 12a and 12b wherein the semi-rigid sheet 4 is coated with a glue
  • connection steps 13a and 13b wherein the sheet is turned over such as to allow the completion of all the folding operations of the lateral bands 5 and 7 by raising the bands above the supporting surfaces.
  • the box forming process is carried out continuously, with the semi-rigid. sheets 4 kept moving, and accordingly and advantageously the.lateral bands being folded will always be the ones arranged parallel to the direction of movement of the semi-rigid sheets. Therefore, it will be necessary to vary the directions of movement of the semi-rigid sheets 4 such as to involve all the lateral bands, as shown in Figure 1.
  • the foregoing method which provides for the assembling of the boxes in question by manipulating separately and sequentially the lateral bands, and with displacements and turnovers of the sheets such as to enable manipulation by raising the lateral bands themselves and acting on-the-fly thereon, makes possible the realization of a potentially fully automated system, for implementing said method.
  • the invention provides, as shown in Figures 4 to 20, for the boxes in question being formed completely by means of a series of automated operations carried out on machines which can be grouped together to form a single continuous production line.
  • the machine which defines the auxiliary processing line 15 of the system substantially comprises, as shown in Figure 4, a loading station 17 whereat the semi-rigid sheet 4 of Figure 4 is laid down positioned with the first lateral bands 5 parallel to-the direction of lay of the line 15 itself.
  • the sheet 4 is caused to advance by entraining members 18, shown schematically, which comprise, for example, entrainment chains.
  • the sheet 4 moves from the loading station 17 to glueing members 19 which are constructed to apply a glue or cement to the first lateral bands 5, as taught in the cited auxiliary step 12a.
  • the glueing members 19 are controlled, for example, by a sensor which detects the passing and exiting of the sheet 4.
  • folding members 20 which, by acting on the moving sheets on-the-fly while being entrained by the entraining members 18, force the first lateral bands 5 to fold upon themselves and adhere closely.
  • the structure of these folding members 20 may be any one, and in particular may be similar to that of the pre-folding elements which will be described with reference to the main processing line 16.
  • the sheet 4 is arranged with its face 2a, which is intended to remain on the box inside, facing upwards, and the first lateral bands 5 are obviously folded such that the outer face 2b prevails on the inner face 2a. It follows that, for the transition from the auxiliary processing line 15 to the main processing line 16, there must be inserted a turnover device if the transition is carried out in an automated manner.
  • the sheet 4 In the event of manual transition from the auxiliary processing line 15 to the main processing line 16, the sheet 4, with the first lateral bands 5 already folded upon themselves but still substantially coplanar with the base 2, must be positioned by an operator onto a starting station 21, with the second lateral bands 7 parallel to the direction of advance on the line 16 and the outer face 2b facing upwards.
  • Figures 6 and 7 show how from the starting station 21 the sheet 4 is inserted, by means of a reciprocating translator element 22, to contact first entrainment devices 23 of the chain type which force the sheet to advance.
  • the second lateral bands 7 contact pre-folding elements 24, shown schematically in Figures 6 and 7, as well as in Figure 5, which strain-relieve the folds in the lateral bands 7.
  • pre-folding elements are shown in detail in Figure 8; they comprise first guides 24a so warped relatively to one another as to fold the second lateral bands 7 in two; first straighteners 24b, which substantially bring the second lateral bands back to a situation of coplanarity with the base or bottom 2 and are defined by bearings arranged to press on the folds; second guides 24c which fold the second lateral bands at their bordering line with the base 2; and second straighteners 24d.
  • the cited folding members 20 are similar to the pre-folding elements 24, e.g. comprising guides so warped as to fold the first lateral bands 5 and bearings which confirm by a sqeezing action the prepared fold.
  • the first entrainment devices 23, and the pre-folding elements 24, are terminated at a glueing station 25.
  • the semi-rigid sheet 4 with the first lateral bands 5 folded and glued, and the second lateral bands 7 strain-relieved along the folding lines, is held above a grid 26 wherethrough a grid-like template 27 can be raised which is wetted with glue.
  • Said sheet is positioned with its inner face 2a facing the grid 26, and the exact position is ensured, where the first entrainment devices 23 are terminated at a distance from the glueing station, by a pusher element, not shown.
  • quadrangular grid template 27 has proved itself to be suitable to create a concentration of cement or adhesive along the creasing (fold) lines of the carton sides, which concentration enables the carton sides, as folded perpendicularly to the sheet, to be stiffened, and accordingly to impart high strength features to the completed carton.
  • Figure 9 shows in particular that the template 27 is carried on a stem 28 which can be controlled to move upwards by a fluid-dynamically operated cylinder.
  • a fluid-dynamically operated cylinder An accurate and strong contact between the template 27, wet with glue, and sheet 4 is provided by the backing action of a turnover element 29, more clearly visible in Figures 9 and 10.
  • the turnover element 29 comprises a tilting plate equipped with suction cups 30, which plate, by rotation about a substantially horizontal pivot pin, can move from a position whereat it re p ts onto the sheet 4, at the glueing station 25, to a fully tilted position with the suction caps upside down.
  • the turnover element 29 entrains the sheet 4 therealong, by virtue of the suction cups 30, thus moving the sheet from the glueing station 25 to a delivery station 31 defined by the turnover element itself, in its turned over condition.
  • the sheet 4 is presented into the delivery station 31 with its outer face facing up and arranged along a transverse line of movement to the one followed up to that moment, as shown in particular in Figure 5.
  • the sheet 4 is inserted, as it is entrained by said suction cups, between first side ridges 33 which force the first lateral bands 5, previously folded over and glued, to arrange themselves at 90 0 to the base or bottom 2.
  • a carriage pusher 32 actuated by a fluid-dynamic cylinder and shown particularly in Figures 10 and 11.
  • the carriage pusher 32 is reciprocated along a parallel direction to the first lateral bands 5 and first side ridges 33, thus carrying the sheet 4 to either of two final stations 34, whereat the box forming process is completed, as shown in Figures 11 to 20.
  • turnover element 29 and carriage pusher 32 define second entrainment devices.
  • linkages and detent elements which alternate operatively to one another, and inserter means effective to apply said shaped plate 12.
  • said linkages and detent elements are defined by second side ridges 35 arranged as an extension from the first side ridges 33 and being overlapped by strips 36 set to protrude partially such as to prevent the raising of the sides defined by the first lateral bands 5; by pin-type pushers 37 located at the ends of the second side ridges 35 and movable transversely thereto; by tiltable sides 38 extending transversely to the second side ridges 35; by a stop 39 intersecting the tiltable sides 38; and by folding arms 40 which oscillate and are positionable with their working ends above the tiltable sides 38, when the latter are in their raised position.
  • the pin pushers 37 are provided, as shown in Figures 12 and 13, to fold the tabs 6 inwardly and set them aligned with the second lateral bands 7.
  • the pin pushers 37 are controlled to retract upon the tiltable sides 38 being raised as shown in Figure 14, thus forcing the second lateral bands 7 to arrange themselves substantially at 90° to the base or bottom 2 of the sheet being folded. It is to be noted that before operating the pin pushers 37 and tiltable sides 38,- the semi-rigid sheet 4 is properly positioned by a stop 39 which is partly inserted through a slit in the aides 38.
  • These arms carry out the folding of the end flaps of the second lateral bands 7 prior to the operation of the cited inserter means.
  • the latter as shown particularly in Figures 11, 18, 19 and 20, are in the form of rocker paddles 41 having suction cup elements 42 for supporting the shaped plates 12 and inserting them between the sides 3 of the-box.
  • the paddles 41 are so constructed as to perform themselves the final folding of the second lateral bands 7. As shown in Figure 18, as the paddles 41 are inserted, the arms 40 are retracted and ( Figure 19) the shaped plates 12 fully fold upon themselves the second lateral bands 7, thus enveloping the tabs.
  • fluid-dynamically controlled pressers 43 which (Figure 20) squeeze the second lateral bands 7 such as to enhance the fold, and then move back to a retracted position in order to permit the raising of the paddle which supports them.
  • the system may include a number of auxiliary members, such as a perfuser 44 at the glue supply and others, the final stations 34 being in any desired number.
  • the materials used, the number and dimensions of the various members, as well as their relative positions, may vary in accordance with the size of the die-cut sheet blank, it being contemplated, according to the invention, that said sheet may be made substantially square to form a cover and bottom separately, or rectangular for the formation of a carton or case.
