For the upward folding of the walls of the foldingbox-blanks one employed heretofore devices in which the blank was first separated from a supply stack and then transferred to an erection station. At this station, the blank is pressed by a plunger between guide members. These known devices require much space, are complicated and expensive. Besides, there frequently occur disturbances on the path from the stack to the erection station.
The device according to the present invention overcomes these disadvantages in that it has a receiving device for a stack of blanks, below which a suction plunger is movable downwardly and upwardly for drawing downwardly the bottom of the lowermost blank, and for feeding the blank between downwardly projecting guide members, which bring about the folding-up of the walls of the blank and their mutual plugin-fastening to the edges of the box.
The drawing illustrates diagrammatically by way of example an embodiment of the invention.
In the drawings:
FIG. 1 is an elevation view of the erection device in a first operativephase.
FIG. 2 is the same view in a second operating phase.
FIG. 3 is the same view in a third operating phase,
and
FIG. 4 is a plan view as in FIG. 2, with omission of all stacked'blanks up to the lowermost, and
' FIG. 5 a perspective showing of an erected blank.
The device shown is intended for the erection of cardboard blanks, which are supplied to the same device in the form of a stack 41, which is inserted between four vertical posts 42, arranged in the corners of a rectangle'In FIGS. 1 to 3, are shown only a few of'the lowermost blanks 40 of the stack 41, each in the form of a single-line. The shape of the blank 40 is apparent sheet-metal guides 49 to 52 inwardly and downwardly.
The upper parts of these sheet metal guides 49 to 52, which are reinforced in a manner not described in greater detail, are curved inwardly convexly, while their lower parts project vertically-downwardly,and accordingly delimit a shaft 53 of rectangular crosssection. This shaft-cross-section corresponds with the 7 .bottom 1 of the blank 40 delimited by the fold-lines 2,
which is in communication with the bore of the tubular piston rod 55 and with a vacuum conduit,.not shown,
and by the interruptions 58 is also in communication with an outer suction chamber delimited 'by the ribs 56 and 57. The suction chambers 59 and 60 serve for the sucking in of the lowermost blank 40,, so that the same is held securely on the ribs 56 and 57, whereby the innermost rib 57 solely prevents too strong a bending of the bottom of the blank 1.
Below the'suction piston 54 is disposed a control piston 61, whose vertical piston rod 62 is movable parallel to thetubular piston rod 55 and likewise is movable upwardly and downwardly. The piston 61 has on its circumference two lateral, symmetrical grooves 62', in
each of which a roller 63 is slidable. Each of the rollers.
63 is rotatably attached to the free end of an arm 64, which is seated on a shaft 65, which is mounted in a support 66 projecting downwardly from the piston 54. At both ends of each of the shafts 65 is mounted a grip per 67, whose upper end is bent at :a right angle to form a claw 68. In FIG. 4 the parts 63 to 66 are not illustrated, and of the four grippers 67 solely the claws 68 are shown, which penetrate the short corner slots 21 in the upper sideof the blank 40,.
In the operating phase illustrated in FIG. 1, the pistons 54 and 61 are disposed in their uppermost position, whereby the suction piston 54 sucks in the lowermost blank 40,. Then the pistons 54 and 61 move downwards and indeed, the control piston 61 moves faster than the suction piston 54, as is indicated by the unequally long arrows 69 and 70. In view thereof, the two arms 64 with their shaft 65 and the associated grippers 67 are pivotal symmetrically inthe direction of the arrows 71 of FIG. 1, until the claws 68 reach the position indicated in the FIGS. 2 and 4, in which they clamp tight the bottom portion 1 of the blank on the suction piston 54. According to the operating phase shown in these Figures, the two pistons 54 and 61 move firstly equally fast downwardly, as is indicated by the equally long arrows 72 and 73. During this downward movement, the one wall 4 together with the edge strips, 7 comes in contact with the sheet-metal guides 49, the one-wall 5 with the sheet-metal guides 50, the other wall 4 together with the associated edge strips 7 with the sheet-metal guides 51, and the other wall-5, the cover 9 and the edge strips 11 with the sheet-metal guides 52. The upper inwardly convex parts of the directed substantially upwardly, so that the suction force carried out by the suction piston 54 on the bottom 1 would not be sufficient to hold the same tight on the piston 54; nevertheless this is obtained satisfactorily by the claws 68 of the gripper 67.
In addition, in this1 manner, the walls 4' which are in connection through the fold-lines 2 with the bottom 1 are held tight on the suction piston 54. On the walls 5, to the contrary, whose outer ends are separated by the corner slots 21 from the bottom 1, the fastening effect of the gripper 67 is. not effective. The ends of these walls to which the flaps 14 are linked may accordingly in each case during the erectionand plugging-inoperation slide somewhat as compared with the walls 4, in direction of the rim formed by the walls 4 and 5. Thereby the prerequisites are furnished which make possible a satisfactory, automatic formation of the boxes, without subjecting the blank to excessive strains.
In FIG. 3 is shown an operating phase in which still only the cover 9 and the edge strips 11 engage the sheet-metal guides 52 while the erected 'plug-in,'folding box 74, otherwise has already left the shaft 53. Shortly before attainment of the position shown in FIG. 3, the speed 72 of the control piston 61 has been reduced with respect to the speed 73 of the suction piston 54, so that the relative position of both pistons 54 and 61 again corresponds to that shown in FIG. 1. The grippers 67 are accordingly again pivoted outwardly, so that their claws 68 have released the box 74. The two pistons 54 and 61 movenow still one step on downwardly with the same speeds 75 and 76, until finally also the edge strip 11 leaves the shaft 53. Then the vacuum in the suction chambers 59 and 60 is abolished, so that the box 74 by means of a slide member, or the like, not
shown, may be transferred from the suction piston 54 to a discharge-conveyor-belt, which for example, leads to a filler station.
The sheet-metal guides 49 to 52'for the purpose of facilitating the illustration and the understanding are not shown in their full width. In FIGS. 1 to 4, as is indicated solely in the right-hand lower corner of FIG. 4, the sheet-metal guide 51 is also provided with an edge strip 5111, which is disposed on the'respective side of the adjacent wall 4 under its corner flaps 26 and their plug-in tongues 25. Furthermore, the sheet-metal guide 50 is also provided with an edge flap 50a, which is located on the respective side of the adjacent wall under its corner'flap 14. The same holds true also for all other'sheet-metal guides. Through suitable, empirically easily determinable curvatures of the sheet-metal guide and their edge strips or edge-flaps, respectively, it is attained that upon upward folding of the walls 4 and 5, first on each common corner edge, the corner flap 25 of the wall 4 is placed on the inner side of the wall 5, whereupon the comer flap 14 of the wall 5 is placed on the inner side of the wall 4, while at the same time, the plug-in tongue 26 of the wall 4 passes through the slot 15 provided along a part of the fold-line l3, lies on the inner side of the wall 5, and prevents an undesired folding apart of unfolding of the erected blank, that is, of the folded-up and plugged together box 74. This is also apparent from FIG. 5, which shows the plug-in-folding box in the condition in which it leavesthe'folding device.
Advantageously the table 43 is provided with stops 69 in the range of the corner flaps 14. During the removal of the individual blanks 40 from the stack 41, the flaps 14 moves over the inner edges 70 of the associated stop member 69 and are thereby subjected to a bending stress. This has the result that the tongue delimited by the notches 15 and 17 is released from the flap 14, which works out to advantage upon plugging-in of the tongue 26 in the slot 15. Thisis then of particular importance when the slots 15 and 17 are not stamped out quite satisfactorily.
It is clear that countless variations of the device shown are possible. Thus one may for example, in place of providing for each a pair of sheet-metal guides 49 to 52, provide a single sheet-metal guide, which extends over the entire length or width of the bottom and is provided in addition on both sides with edge flaps or edgestrips, respectively. Furthermore, one may replace the sheet-metal guides 49 to 52 by corresponding guide members made of other material than sheet metal. The actuating mechanism for the grippers 67 does in no manner need to have the described control pistons 61, although the same is especially simple and advantageous. The table 43, on which the stack 41 rests, need not consist ofa solid table-plate, but may also be grateshaped or frame-shaped. I
Finally it is pointed out that the concepts under, downward, upward, lowermost blank and the like, in the preceding description and the following claims relate to the position of the device coming into question as shown in the drawing. These device would also remain capable of functioning upon a change in its spatial orientation, in that'one could also tilt it as a whole for example by or with reference to the vertical direction. I
