Definitions

  • the present invention relates to a system for feeding sheet products to a machine for processing said products.
  • the system according to the invention is more particularly suitable, although not exclusively, for the continuous feeding of cardboard blanks from a machine allowing the manufacture of packaging from said blanks.
  • the system according to the invention is not limited to this type of product, but could also be used for products such as plates, panels, etc. made of different materials, other than paper, such as, for example, metal, glass, synthetic material, etc.
  • some of the systems for feeding sheet products, such as cardboard blanks, to a machine intended for making packaging or the like from said blanks include a storage magazine, arranged upstream of the machine and comprising a stack of cardboard blanks, and a transfer device authorizing the taking of the upper blank of the stack to bring it towards the table of the machine and place it thereon.
  • the object of the present invention is in particular to overcome this drawback and relates to a system for feeding sheet products to a machine for processing said products, which prevents an operator from frequently reconstituting the storage magazine of said system while allowing the machine to '' be regularly and automatically fed sheet products without interruption.
  • the system for bringing sheet products to a deposit area of a machine for processing said sheet products comprising means for storing said sheet products and a device for transferring, one by one, said sheets. products of the storage means at said machine, is remarkable, according to the invention, in that said storage means comprise at least first and second magazines, and, in that said transfer device comprises at least first and second means for gripping said products, arranged and controlled so that, when one of the gripping means grasps the product in the upper sheet of the corresponding storage magazine, simultaneously, the other gripping means deposits on said zone for depositing the machine the product in upper sheet, previously seized from the other storage store and then transferred to said machine, and vice versa.
  • the system offers greater operating autonomy allowing the machine to be supplied continuously, without an operator intervening frequently.
  • the system allows the sheet products to be brought to a high speed in the direction of said machine.
  • said transfer device may comprise two arms fixed to a shaft capable of being driven alternately in rotation by a motor member, each of said arms carrying one of said gripping means and being capable of moving between two separate positions, one of which is located above the corresponding storage magazine and the other of which is located above the machine removal area.
  • the second gripping means of the other arm deposits the upper sheet, previously gripped of the second storage magazine, on the machine removal zone, then, by rotation of the arms driven by the motor member via said shaft, the second gripping means, stripped of sheet, comes into contact with the upper sheet of the second means storage, while, simultaneously, the first gripping means deposits on the machine the sheet, previously gripped.
  • the movement of said arms takes place in a plane parallel to the plane of said sheet products, the movement of said gripping means being carried out orthogonally to these planes and parallel to the shaft driven alternately in rotation.
  • said arms fixed by one of their ends to said shaft, form between them an angle of 90 °
  • said motor member which drives in rotation through the shaft said arms, being a motor reversible electric.
  • each of said gripping means may comprise a jack whose cylinder is linked to the corresponding arm of the transfer device and whose rod is provided at its end with controllable suction cups capable of ensuring the taking up and the transfer of a product in sheet of the storage magazine corresponding to the removal zone of said machine.
  • the rotation of the arms via the drive member and the shaft takes place when the jacks are in the high position, the drive member does not operate when the jacks are in the low position.
  • each gripping means is capable of occupying two distinct positions along said corresponding arm, a first position, distant from the axis of rotation of the shaft, corresponding to a position for which said means of gripping is located above the machine removal zone, and a second position, close to the axis of rotation of said shaft, corresponding to a position for which said gripping means is located above the storage magazine corresponding.
  • This arrangement thus makes it possible to reduce the spacing between the two storage magazines, and, consequently, to reduce the space requirement of the system in the workshop.
  • the two stores can thus be arranged practically side by side.
  • each gripping means is mounted on the corresponding arm by means of a support capable of sliding, during the rotation of said shaft, along the arm between the two said positions, close and distant from the axis of rotation of said shaft, thanks to a connecting rod, one end of which is fixed to the chassis of said system and the other end of which is connected to the corresponding gripping means.
  • the two connecting rods of the chassis to the gripping means move in superimposed planes, parallel to the plane formed by said arms.
  • said system may include means for detecting and upgrading the sheet products of each storage store. These means make it possible to bring, each time a sheet has been gripped and then transferred to the depositing area of the machine, the sheet product then superior of each stack to a determined reference level, so that the suction cups equipping them each time come into contact with said product in upper sheet to grasp it, then transfer it.
  • said means for detecting and leveling each store comprises at least one photoelectric cell fixed to the chassis of said system and a control member allowing the mounting of said store, so that when the product in the upper sheet of said magazine is seized then transferred, a light beam is transmitted by said cell, which causes the actuation of said control member and the rise of said magazine until the new top sheet of the stack interrupts the transmission of the light beam, then stopping said control member.
  • replacement magazines each containing a stack of sheet products can be provided upstream of said first and second storage magazines, said storage and replacement magazines based on controllable displacement means enabling said replacement magazines to be replaced by said storage magazines, when the sheet products of the latter are used up.
  • the operating autonomy of said system is further increased, which allows the operator to intervene, for example, only daily, or even less, in the various machine stores.
  • said first and second storage magazines as well as said replacement magazines respectively, arranged upstream from the storage magazines, are aligned by forming two parallel queues, the transfer device being provided between the two queues near the drop-off area. of said machine.
  • Each row of magazines can then be arranged on controllable displacement means comprising a belt conveyor driven by a motor, and, moreover, the storage and replacement magazines can advantageously be arranged on the conveyor of each queue in a regularly spaced manner. .
  • the magazines aligned in N stacks can be driven in translation by the displacement means so that, when the stack of storage magazines is exhausted, the following N stacks advance by a step corresponding to the distance separating two successive stacks, the first of the replacement magazine batteries replacing the storage magazine battery, and so on.
  • the system according to the invention is particularly intended for feeding sheet products, such as cardboard blanks, to a machine for processing said products.
  • the system 1 comprises means 2 for storing sheet products, namely cardboard blanks 3 arranged in the form of a stack 4, and a device 5 for transferring, one by one, the blanks 3 of the storage means 2 at a deposit area 6 of a processing machine 7.
  • the storage means 2 comprise a first, 8, and a second, 9, magazines, each magazine consisting of a stack 4 of cardboard blanks 3 resting on a pallet 10, which is arranged on controllable displacement means 11. Behind each storage magazine 8 and 9 is provided at least one replacement magazine, respectively 12 and 14, identical in constitution to that of stores 8 and 9. It can be seen, in particular with regard to FIG. 2, that the storage stores 8 and 9 and the replacement stores 12 and 14, respectively arranged upstream of the stores 8 and 9, form two parallel rows, the transfer device 5 then being located between the two rows, close to the removal zone 6 of the machine.
  • the controllable displacement means 11 of each row comprise a conveyor 15, for example of the belt type, capable of being set in motion, which thus makes it possible to bring the replacement magazines 12 and 14 to replace the storage stores 8 and 9, when the cardboard blanks 3 of the latter are exhausted, as will be seen later.
  • Each conveyor 15 can advantageously be associated with a device, not shown, for forming stacks of products resting on the pallets of the storage and replacement stores.
  • a device for forming stacks of products resting on the pallets of the storage and replacement stores.
  • Such a device is, for example, described in French patent application FR-A-88 10830 filed in the name of the Applicant and makes it possible to form stacks of strictly vertical products while being, moreover, regularly spaced along the conveyor .
  • the storage stores 8, 9 and replacement 12, 14 thus offer the system considerable autonomy in operation, which allows the processing machine 7 intended, for example, to produce packaging from said blanks, to be able to operate without interruption and automatically for a long time.
  • the transfer device 5 schematically illustrated in FIGS. 1 to 3, comprises first, 18, and second, 19, means for gripping said sheet products, that is to say, in this application, the blanks 3 of cardboard.
  • first and second gripping means are arranged and controlled so that, when one of the gripping means grasps the blank upper of the corresponding storage magazine, simultaneously, the other gripping means deposits on the removal zone of the machine the upper blank, previously gripped from the other storage magazine and then transferred to the machine, and vice versa.
  • FIGS. 1 to 3 it can be seen that the first gripping means 18 is ready to grip the upper blank 3 of the stack 4 of the magazine 8, while the second gripping means 19 is ready to deposit on the area 6 of the machine the blank 3 previously entered from the stack 4 of the magazine 9, then transferred.
  • the device 5 thus operates in the manner of a turnstile, each gripping means moving by alternating rotation, between two distinct positions.
  • each conveyor 15 is, for example, made up of two profiles 23, parallel and spaced, and two endless belts 24, each cooperating with a profile, capable of being driven, in a synchronized manner, in rotation by pulleys.
  • each conveyor (shown in phantom in Figure 4), on which the pallets 10 of the storage and replacement stores rest, are set in motion by an electric motor, respectively 25 and 26.
  • L drive of each motor 25 and 26, fixed to the chassis 20, to the bands of the corresponding conveyor is carried out by means of a mechanism 28 with eccentric and belts 29, well known in this field, which allows a slow and progressive starting of the conveyor, then a substantially constant speed thereof, to be completed by a gradual deceleration until stopping.
  • This mechanism 28 thus allows said stacks of products to remain plumb on each conveyor, avoiding their tilting.
  • the path of the belts 29 of the mechanism 28 is illustrated in dashed lines in FIG. 4.
  • the transfer device 5 comprises two arms 30 and 31 fixed to a shaft 32 capable of being rotated alternately by a motor member 33 fixed to one of the side members of the chassis 20.
