Definitions

  • a control piston I 0 care 53 actuates pivotally mountedgrippers which enter into I corner slots at the bottom forming portion of the blank and clamp the bottom of the box against the [56] uNlTE g g; r E s giqrENTs suction piston during its downward movement.
  • 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.
  • FIG. 1 is an elevation view of the erection device in a first operativephase.
  • FIG. 3 is the same view in a third operating phase
  • 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 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.
  • 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
  • a 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.
  • a grip per 67 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.
  • 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,.
  • 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.
  • 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.
  • the two pistons 54 and 61 move firstly equally fast downwardly, as is indicated by the equally long arrows 72 and 73.
  • 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.
  • 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.
  • 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.
  • 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
  • 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.
  • 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.
  • 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.
  • the table 43 is provided with stops 69 in the range of the corner flaps 14.
  • 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.
  • Device for the erection of blanks for making plugin-folding boxes comprising receiving means for a stack of blanks, guide members extending downwardly from said receiving means, an upwardly and downwardly movable suction piston arranged below said receiving means for sucking in the bottom portion of the lowermost blank of said stack and drawing it downwardly between the guide members to prodice an upward folding of the walls of the blank and their mutual plug-in-fastening to the edges of the folded box and pivotably mounted grippers, when after an introducing downward movement of the suction piston during which theportion of the blank is separated from the remaining stack, enter slots in the blank and engage its bottom portion for clamping the same to the suction piston.
  • Device including an upwardly and downwardly movable control piston, which through an advancing or lagging movement with reference to the suction piston controls said grippers in such manner that the same engage and release the bottom portion, respectively, of the blank.
  • each of the guide members has an upper portion which is convex inwardly to a vertically extending lower portion, the guide members being arranged with their lower portions forming a rectangular shaft for the passage of the blank during the folding operation.
