Definitions

  • the present invention relates to a stapling machine, intended in particular for assembling planar elements, in particular cardboard blanks in the context of the manufacture of packaging cases, this machine comprising a support plane on which the elements to be stapled are called to scroll and an oscillating stapling device mounted on the frame of the machine, facing the support plane, and coupled to an actuating mechanism capable of rotating it in one direction and in the other, around a main axis substantially perpendicular to the direction of travel of the elements to be stapled and within the limits of an angular range of variable amplitude.
  • the present invention proposes to remedy all these drawbacks and, to do this, it proposes a stapling machine of the aforementioned type, which is characterized in that it comprises means for varying the amplitude of the pivot range of the stapling device, means which consist of a mechanism for adjusting the distance from the main pivot axis of the stapling device, relative to the bearing plane of the elements to be stapled.
  • the adjustment mechanism comprises, according to a preferred embodiment of the invention, a guide sleeve in which the connecting rod is inserted with free sliding, a positioning arm on which the guide sleeve is mounted pivoting about an axis constituting the main pivot axis of the stapling device, this arm being articulated on the frame of the machine, around a second axis parallel to said main pivot axis and distant from the latter, and control means coupled to the positioning arm to bring it and immobilize it in a chosen angular position.
  • said control means comprise an electric motor driving in rotation at least one member screwed onto a respective threaded rod articulated to the positioning arm, at a point located between the main pivot axis and the second axis.
  • the technique for adjusting the range of the oscillating movement of the stapling device consisting of bringing the stapling elements closer or further away from the bearing plane, is to implementation much simpler and faster than manual interventions that until then had been necessary to practice directly in the actuating mechanism of the stapling device.
  • this adjustment can also be done during the operation of the stapling machine, since the guide sleeve can slide along the connecting rod without hampering its oscillating movement.
  • the adjustment mechanism according to the invention therefore guarantees optimum flexibility of adaptation in a production line for packaging cartons, without however affecting the flow rate or the production rate of the latter.
  • the present invention also offers the advantage of a possibility of automating the adjustment of the pivoting range of the stapling device, which can be obtained by placing the electric motor driving the positioning arm, under the order for example from a detector of the running speed of the elements to be stapled.
  • the stapling machine according to the invention is built around a frame 1 which, in a manner known per se, carries a stapling head 2, single or double (shown in dotted lines), suspended above a horizontal support plane 3 (shown in broken lines), defined by cleat chains or conventional flexible belts.
  • the elements to be assembled mutually by stapling in this case cardboard blanks, arrive on this support plane from the preceding post, namely the folder, and pass continuously under the stapling head 2 under the ripple effect of chains or belts.
  • the stapling head 2 acts cyclically, to place each time a staple or a pair of staples on two blanks to be assembled, under the control of an eccentric actuation mechanism (not shown) wedged on the rotary shaft 4 mounted in the upper part of the frame 1.
  • the stapling head 2 can, in a manner also known per se, oscillate in the direction D of this movement. To do this, it is fixed to a support block 5 articulated at the bottom of four suspension arms, only two of which 6, 7 are visible in FIG. 1, these arms 6, 7 being themselves articulated at 8 and 9 at machine frame 1.
  • a riveting pallet 10 is likewise suspended from the frame 1, by means of four arms 11, 12 (shown in part) and is further connected, by articulated links 13, to the support block 5 of the stapling head, to follow the movement oscillating from the latter.
  • This oscillating movement of the stapling head is more precisely produced by a control rod 14 which, under the control of an eccentric actuation mechanism 14 wedged on the rotary shaft 4 (shown in a tearing of the frame on the Figure 1), can rotate, in one direction and in the other, around a horizontal axis X substantially perpendicular to the direction of advance D of the elements to be stapled.
  • the articulation 16 between the control rod 14 and its actuation mechanism 15 is further supported by an elbow lever 17, itself articulated to the frame.
  • the control rod 14 is coupled, by an articulated link 18, to the front of the support block 5 of the stapling head.
  • a mechanism is provided for adjusting the amplitude of the pivoting range or of the oscillating movement of the control rod 14 and, consequently, of the stapling device constituted by the stapling head. 2 and the riveting pallet 10 which extends under the latter to cooperate with it.
  • this adjustment mechanism comprises a positioning arm 19, a first end of which is articulated on the frame 1, around an axis Y parallel to the pivot axis X of the connecting rod 14.
  • the arm 19 which is in fact essentially formed by two parallel branches 20, 21, carries, at its second end, a guide sleeve 22 (shown in a cutaway in FIG. 1) pivotally mounted, between these two branches, by two lateral pins 23, 24 (see FIG. 2) which define the pivot axis X, this sleeve 22 freely sliding receiving the control rod 14.
  • the positioning arm 19 is, at its middle part, suspended, by two rods of articulated vertical connection 25, to a mechanism for controlling its angular position, shown diagrammatically in FIG. 4, the two connecting rods 25 being articulated at 25a on the arm 9.
  • this control mechanism comprises a small electric motor 26 driving, by means of a transmission 27, 28, a first horizontal pulley 29, the hub of which is screwed onto a vertical threaded rod 30, articulated by its lower end, at the top of one of the connecting rods 25, as indicated at 31 in FIG. 1.
  • a belt 32 passes around the pulley 29 and a second horizontal pulley 33, the hub is screwed onto a second threaded rod 34, parallel to the first and articulated at the top of the second connecting rod 25.
  • the pulleys 29, 33 and the belt 32 can of course be replaced respectively by toothed wheels and a chain.
  • FIG. 2 shows the structural details of the guide sleeve 22.
  • this guide sleeve 22 consists of two parts, namely a main shell 35 which carries the two pins side 23, 24 and a cover 36 which is assembled by screws 37, 38 to the shell 35, after positioning of the control rod 14 inside the latter.
  • the shell 35 and the cover 36 delimit, after assembly, a sliding cavity 39 of rectangular cross section.
  • the rod 14 is applied only against the four corners of this cavity 39 by four longitudinal bearing surfaces 40 forming a single piece with a central core 41 in the form of H.
  • This special machining of the control rod 14, which aims to minimize friction, will in principle be limited to the section thereof, on which the sleeve 22 is called upon to slide (see FIG. 1). However, it will be good to cut or hollow out the remaining part of the connecting rod 14 to reduce the inertia.
  • a wedge-shaped take-up key 43 is retained, on the correspondingly shaped inner face of the cover 36 of the guide sleeve 22, by a screw-nut assembly 44 joining two external extensions 45, 46 of these two parts. It is in fact this key 43 which defines, with the shell 35, the sliding cavity 39 of the guide sleeve.
  • the use of the key to take up play 43 avoids the need for precise sizing of the cavity 39.
