Definitions

  • the present invention relates to a servo device organs delivering sheets from a stack to a machine working.
  • a device described in CH 651 807 comprising a lifting mechanism said stack, a sheet introducing member provided with a gripping, means for detecting the upper level of said stack comprising a detector of the front level of said battery connected to a computer acting on an electric motor of said lifting mechanism of said stack and means for raising said stack according to said level superior.
  • a command to raise this battery is sent to the motor drive which drives the stack elevating mechanism by impulse.
  • the duration of the pulse is modulated to obtain steps of rise of variable size, allowing to bring back the top surface of the stack at the same level consecutively at the start of each sheet of this stack.
  • the object of the present invention is to remedy, at least in part to this disadvantage.
  • the subject of this invention is a device for controlling the organs delivering sheets from a stack, to a machine working them, as defined by claim 1.
  • the feeding station represented by figure 1 is of the type of that described in CH 651 807 to which reference may be made for more details. It includes a stack elevator with a lifting grid 1 suspended from chains 2. One end of each chain 2 is attached to the lifting grid 1 by means of legs 3 at least minus two, preferably four, placed on either side of the stack sheet feed 4. Each chain 2 is connected to its other end, to a fastening piece crossed by a screw. Each chain 2 passes around a chain wheel 7 mounted on shafts 8.
  • a device ensures the vertical drive of the lifting grid 1 by the chains 2. This device may be constituted by the attachment piece which is of course guided during its movement along the screw by slides (not shown). The opinion is supported by two bearings (not shown) and driven by a motor reduction gear 11 fitted with an encoder 41. It is obvious that any motor-reduction device capable of generating the rotation of the shaft 8 secured to the wheels chains 7 can be used.
  • the introduction station also includes a fixed suction group 12 on a frame 13 suspended from the end of at least one, in this case at least two chains 14 via fixing lugs 15.
  • the other end of the chains 14 is fixed to the output axis of a linear motor 18.
  • One end of the frame 13 rests so that it can slide on a spacer 24 while the other is fitted with a guide arranged in the supports 27 fixed on each of the lateral uprights 28 of frames 47, 48 of the feeding station. This provision ensures an unchanged position of the suction group 12 relative to the rear edge of the stack of sheets 4, when it goes up or down under the action of the motor 18.
  • the suction unit 12 includes several suction cups 29 (only one has been shown to simplify the drawing), as well as a first detector member 30 which will be described in more detail below. It is specified that the sucking group 12 is only described to understand how sheet feeding is done but that this known sucking group 12 is not part of the present invention and will not be described here in all its details.
  • the first detector member 30, which includes a crowbar 19 and a reading cell 20, is placed in the vicinity of the upper part back of the stack of sheets 4 on a theoretical axis corresponding to the axis theoretical median of the stack of sheets 4.
  • a second detector member 32 is placed in front of the upper front part of the stack of sheets 4 on the axis median of this stack.
  • This second detector member 32 consists of preferably by a fixed linear camera arranged in the height direction of the stack of sheets 4, so as to provide an analog signal depending on the level measured.
  • a retractable front stop 33 is pivotally mounted around a axis 34, near the upper level of the front face of the stack of sheets 4.
  • the pivoting movement of the front stop 33 is obtained using a lever 35 controlled by a cam 36, actuated by the drive device of the introduction station fed by the sheets of stack 4.
  • This stop 33 has a window (not shown) centered on the median axis of the stack of sheets 4, to allow the detector 32 to constantly see the level top of this stack 4.
  • the first detector member 30 is electrically connected to one circuits of a computer 37 by a cable 38, while the second member detector 32 is connected to a second circuit of this same computer 37 using of a cable 39.
  • the computer 37 receives a signal from the first detector organ 30, it transmits positive or negative sense information intended to be transmitted by the cable 40 to the motor 18 governing the vertical movement of the sucking group 12.
  • the analog signal supplied to the computer by the second detector 32 allows the latter to evaluate in real time the difference between the upper level of the stack, measured by the second detector 32 and the upper reference level of this stack.
  • This comparison between these two levels allows to form a speed signal at the output of the computer which will be compared to the real-time speed of the reduction motor 11 provided by a encoder 41 associated with this motor.
  • the result of the comparison between these two speed signals is used to change the frequency more or less power supply to the motor through a frequency converter 42 connected to this reduction motor 11.
  • the reduction motor 11 raises the stack of sheets 4 continuously with a speed constantly adapted to the actual level of the stack compared to the reference level.
  • the introduction station can also also include a auxiliary supply device 50, commonly called non-stop (NS), allowing to change the battery without interrupting the flow of leaf.
  • This auxiliary supply device 50 is composed of a frame 51 allowing the establishment of bars 52 supporting the stack when the grid 1 main battery rise reached a level requiring recharging of a new stack of leaves.
  • the introduction of these bars 52 under the main stack allows to form an auxiliary grid while supporting the stack main so that we can lower the grid 1 in position low allowing charging of the new battery.
  • This non-stop device is generally equipped with a drive having a kinematics similar to that of the rise of grid 1, and it comprises inter alia a gear motor 53 intended to drive wheels with chain 54 around which the chains 55 ensure movement vertical of the frame 51.
  • the gear motor 53 is also connected to the computer 37.
