Definitions

  • the present invention relates to a method and a device for the automatic feeding of a machine for treating plate products, and more particularly for the automatic filling of the feed magazine of a machine for treating blanks in plates. This is how it applies particularly effectively, for example, to the automatic feeding of the feeder magazine on a printer slotter with a high production rate for the shaping of corrugated boxes.
  • corrugated cardboard packaging boxes involves a first phase in which the corrugated cardboard is produced in a continuous strip, in a corrugating machine, then cut into rectangular blanks whose dimensions correspond to the development of the box to be produced.
  • the blanks are most often taken one by one in a machine called “slotter-printer", in which they undergo various cuts to form for example the flaps of the box.
  • a machine includes an input element called “feeder”, with a feed magazine where the blanks are stacked to be extracted one by one from the bottom of the stack, at a rate in synchronism with the rotary cutting elements or printing.
  • feeder input element
  • the blanks are stacked to be extracted one by one from the bottom of the stack, at a rate in synchronism with the rotary cutting elements or printing.
  • the cardboard blanks are stacked awaiting passage on the shaping machines, slotter or flat cutting machine.
  • the filling of the slotter supply magazine is generally done manually, by successive removal of packets of plates from a waiting pile.
  • the reserve formed in the slotter magazine generally provides sufficient flywheel, at the end of each stack of blanks, to have time to bring another stack to the slotter and avoid stopping the machine.
  • the stacking of the plates during their transport between the corrugating machine and the shaping machines is never strictly vertical. If therefore, the upper part of the stack has been correctly centered so that the plates arrive well in the axis of the slotter, it is frequent to note that when one arrives at the lower part of the stack, the centering is not more correct and the plates still hardly enter the feeder magazine.
  • this kind of process allows only one package to be obtained at a time, which can constitute, with high rates, an insufficient reserve when a battery change is carried out.
  • Document DE-A-3 021 367 relates to a device for unloading a pallet on which are linked bundles each forming a block in itself. This document simply shows the tilting of the battery, which is only a secondary element of the invention.
  • the machine 1 is normally positioned adjacent to a standby conveyor 12 for supplying batteries (13, 14). These are for example stacks of cardboard plates at the outlet of a corrugator, said plates being intended to be introduced, via the device of the invention, one by one into a machine for forming and printing cardboard boxes. corrugated.
  • the tilting lifting platform 3 is provided with forks 15 which can be moved along a conveyor frame 16 which is orthogonal to them. In its "standing" position shown in dotted lines in FIG. 2, it receives one of the waiting piles, such as the pile 14, the forks 15 being in their extreme low position so as to be inserted in the supply conveyor 12 , the latter being provided with longitudinal spaces accordingly.
  • the tilting of the apron 3 is carried out, in a very conventional manner for this kind of tilting apron, by output from the rod of a jack 17, the base of which is articulated on the chassis 2 of the machine.
  • the apron 3 then swings around the shaft 18 to the almost horizontal position shown in the drawings.
  • the conveyor frame 16 is extended, with a downward offset as seen in the drawings, by a retractable support 4 constituted by forks 19 assembled on a cross member 20 retractable using a jack 21.
  • This support 4 allows you to create a staircase intended to separate by gravity a package from the top of the stack. Its retraction also makes it possible to then drop said package downwards.
  • the top of the conveyor frame 16 is also provided with a device 10 facilitating the separation of packages from the top of the stack, moved by a jack 22 and essentially comprising a separating blade 23, and which will be described in more detail below.
  • the device 5 intended to accompany each pack in its quasi-vertical fall after the separation operation consists of a fork 25 composed of teeth fixed on a crosspiece 26 animated by a cyclic movement back and forth vertically, synchronism with the withdrawal of the support 4. This device 5 will also be described in more detail later.
  • a plate 7 lined with idle rollers is articulated at 29 on the chassis 2 at the level of the support 4, and is used, in its quasi-vertical position shown in FIGS. 1 and 2, to laterally support the packages during their quasi-vertical fall, as well as at the end of this fall.
  • This plate can be raised psr rotation about the axis 29 until it reaches a quasi-horizontal position, by exiting the rod of a jack 27, articulated at its other end on the chassis 2 of the machine.
  • the lateral squaring device for standing packages comprises two joggers 28 adjustable in position according to the format of the blanks, the operation of which will be explained later. Facing the plate 7, when the latter is in the quasi-vertical position, there are three left sheets 8 curved as shown in a slightly enlarged spiral arc.
  • the packet 9 for receiving and discharging the packets is in itself of a new type. It has the advantage of allowing the reception of successive packets by placing these packets in a line, one behind the other as closely as possible, even if the first packet in the series is awaiting evacuation at downstream end of block 9, and even if the packets arrive on block 9 randomly. At any time, the leading packet can be alone evacuated to a processing station located downstream, and replaced in the waiting position it occupied by the second packet without the operation of arriving new packets at the back of the line is embarrassed.
  • the whole of the block 9 is movable from front to back, this to allow access to the machine without the need to move it on its rollers 11.
  • one of the lower sides of the table 30 is furnished with a rack 35 meshing with a toothed wheel 36, the motorization of which is ensured, as shown diagrammatically in the drawings, by a conventional chain device 37, traction cylinder 38, and return toothed wheel 39.
  • Figure 4 is a perspective view of the separation device 10. It comprises a separating blade 23, furnished with teeth as shown, and carried by a roller 24 which can be moved back and forth by retracting and leaving the rod of the jack 22, itself connected to a crankshaft 40 carrying the roller 24 and mounted idly on the axis of the downstream pulleys of the conveyor 16.
  • FIG. 5 The perspective view of FIG. 5 makes it possible to realize how the forks 15 can move along the conveyor structure 16.
  • a motor 41 drives, via a transmission 42 of a shaft 43 and d 'a gear 44, a chain 45 on which is fixed the fork 15.
  • the fork 15 can roll back and forth on the frame 16 by rollers 460 and is integral with the conveyor belt as shown.
  • This device is a direct equivalent to the devices known according to French patents 2,273,656 and 2,359,052, which could very well be used here.
  • Figure 6 is a partial perspective view of the above device 4. It comprises forks 19 fixed on a cross member 20 and supported at the front by a transverse bar 47 fixed to the chassis and furnished with idle rollers 48 each placed under one of the forks. Longitudinal guide elements 49 fitted with lights 50 allow, thanks to rollers 51, the longitudinal sliding of the cross-member 20 by retraction or exit of the rod of the jack 21.
  • Figures 7 and 7a show, in partial perspective and section along aa, the structure of the support device 5 intended to accompany, by their lower edge, the packages in their fall.
  • the cross member 26 carrying the two forks 25 is slidably mounted on quasi-vertical guides 52.
  • the reciprocating movement from top to bottom is given, from a motor 53 fixed to the chassis, by a conventional transmission of the rod-crank type comprising a wheel 54, a first articulated connecting rod 55, and a second articulated connecting rod 56.
  • the connecting rod 56 has one of its ends articulated on the chassis of the machine and its other end mounted sliding along the crosspiece 26 by means of a roller. bearing 57.
  • the device 6 for squaring the packets laterally after their fall is shown diagrammatically in FIG. 8. It comprises two conventional joggers 28, the bases of which can slide in two parallel slides (60, 61) fixed to the chassis of the machine. Said bases are fixed at the end of the rods of two jacks (62, 63) placed in each of the slides (60, 61) and held in these slides by sliding parts (64, 65) each provided with a vertical rod (66, 67) whose end comes out of said slides.

  • the wheel 70 is driven in rotation using a transmission 71 and a motor 72 fixed to the chassis.
  • the position of the jacks (62, 63) is chosen in the rest position.
  • the position of the jacks (62, 63) is chosen so that the spacing of the joggers is greater than the lateral format of the blanks by an amount equal to or slightly less than the sum (c + d) of the strokes of the rods of the jacks ( 62, 63).
  • the sudden retraction of the rods of said jacks thus makes it possible to perform a lateral squaring of the blank pack by action of the joggers 28.
  • FIG. 9 makes it possible to explain the action of raising a package 58 horizontally, after its lateral squaring using the device of FIG. 8.
  • the left sheet 8 has a concave curved shape, widened in a spiral by an angle relative to the arc of a circle C with a center 29.

  • the stop at waiting for the packet 59 to be evacuated at the end of the conveyor 34 is triggered by stopping the latter due to the blackout by the front of the packet 59 of a photocell 77.

  • the tilting apron 3 is then in a standing position, as shown in dotted lines, so that it can receive the stack, shown at 14, on its four forks 15 which are in the low position and inserted into the conveyor 12.
  • the roller (24, figure 4) of the separator 10 is then made to rotate about half a turn in the opposite direction to the hands of a watch, which allows the blade 23 (figure 4), in combination with a slight lifting action due to the roller 24, and possibly to idle rollers (78, 79, Figure 3) optionally mounted on the same axis, to be introduced between two sheets so as to clearly separate a package (80. Figure 11) from the top of stack 14, in exactly the same way as in the aforementioned French patent No. 923,939.

  • the quasi-vertical fall of the package 80 stops when the accompanying device also stops in its extreme low position.
  • the package 80 is then almost always upright on its edge as shown, and the two tabs 28 are then actuated which cause easy lateral squaring of the package since the latter is upright on its edge.
  • the forks 15 are advanced along the frame 16 by a calibrated quantity, sufficient to allow the subsequent separation of a new package 81, the support 4 having of course been previously released and the blade 23 of the separator 10 brought back.
  • the package 80 is brought up by output from the rod of the jack 27, which allows rotation upwards. of the table 7 around its axis of articulation 29.
  • the table 7 then stops, as previously mentioned, in a quasi-horizontal position, slightly inclined towards the front, in alignment with the slope of the block 9.
