Definitions

  • the present invention relates to a method of using machines intended for the reception and stacking of plates with a view to their evacuation at the outlet of a production or processing machine with continuous operation, when such machines have to process plates likely to undergo a format change at certain times.
  • the invention applies more particularly, by way of example, to "automatic longitudinal receivers" placed at the end of a “corrugator” or train of machines with continuous operation for the production of a continuous strip of corrugated cardboard and its plate flow by cutting both longitudinally and transversely.
  • the first conveyor comprises a downstream telescopic part, and are equipped with means making it possible to move this telescopic part so that the discharge point of the first conveyor moves between two positions extremes always located at. above the second transporter; advantageously, these devices are furthermore provided with means for causing the retraction of the telephoto part during the battery changes, as well as its progressive redeployment from the resumption of the formation of the battery.
  • the intermediate stack formed at the end of the exit of the plates of a first format and at the start of the exit of the plates of a second format generally comprises plates of the two types, which it is then necessary to sort manually.
  • the method of the invention makes it possible to avoid this drawback, and therefore to ensure, in the case of a machine with continuous operation, a supply of stacks of plates each comprising only plates of the same format. It is characterized in that it consists in following, as soon as it arrives on the receiving and stacking device, the path of the last plate of a first format and in triggering a change of battery when said plate has left the last carrier.
  • the running speed of the first conveyor is increased when it has collected the last plate of a first format, then this speed is then reduced to a value lower than its normal value when said last plate has left the first conveyor .
  • the speed of travel of the last conveyor is also increased, except during battery changes, at least during the increase of that of the first. In the case where a device is used whose first conveyor has a retractable downstream part, any retraction of said downstream part is advantageously stopped for the duration of the stay of the last first format plate on the last conveyor.
  • the invention also relates to a plate stacking installation equipped with means allowing the implementation of the above-defined product.
  • Such a receiver is placed after a transverse cutter 3 and comprises:
  • a flap 13 At the downstream end of the second conveyor 1 is a flap 13, normally raised so as to allow the sheets to pass during normal operation, and folded down so as to form a stop blocking the passage of the plates during the battery change periods .
  • the actual stacking station is constituted in the usual way for this kind of machine by a lifting table 14, the raising and lowering of which are carried out by a hydraulic system not shown.
  • this hydraulic device is controlled for example by a system of photoelectric cells which detects the upper level of the stack in formation and controls the lowering of the table as and when the stacking of the plates on the stack.
  • the movement of the table 14 is limited by at least one end of travel stop 15, adjustable in height as a function of the batteries to be formed and which supply an electrical signal controlling the triggering of the successive cycles corresponding to a battery change.
  • a normal battery change cycle includes stopping the conveyor 2 and retracting the telescopic assembly (5,6) constituting the downstream part of the conveyor 1, this telescopic assembly then redeploying when the next stack.
  • the stacking station includes a stop 16 adjustable longitudinally according to the format of the plates to be stacked.
  • the conveyors 1 and 2 have been represented in a simplified manner only with the aid of their respective end pulleys (4,5) and (11,9).
  • Each of the pulleys 4 and 9 is coupled to a detector, respectively Dl and D2, providing, on operating command, an electrical impulse per revolution of the corresponding pulley.
  • a position detector D3 is coupled to the end of the telescopic part carrying the pulley 5 and gives a pulse per length of movement of the pulley 5 corresponding to one revolution of the latter.
  • the conveyor 1 transports the plates over a maximum length L1, corresponding to a number of pulses N1 of the detector Dl, and, the pulley 5 being able to retract by a length 1 until it comes into position 5 ′, over a minimum length (L l -2), corresponding to a number of pulses of the detector (Dl) equal to (Nn), n being the number of pulses for the retraction length 1, and the detectors Dl and D3 being identical.
  • the distance traveled between the end pulleys 11 and 9 of the conveyor 2 is equal to L2, and corresponding to a number of turns N 2 of the detector D2.
  • the detectors D2 and D3 being identical, and the distance traveled on the conveyor 2 varying between (L 2 -t) and L 2 , this corresponds to a number of revolutions of the detector D2 varying between (N2-n) and N2, .: 2 being the number of pulses for the length L 2 .
  • the pulses of D1 and of D2 are counted by counters C1 and C2 each comprising a trigger output (17,18) by respective pre-displays N1 and N2.
  • the position detector D3, relating to the retractable pulley 5, sends, in the event of advance of the pulley 5, counting pulses on the counter C2 and countdown on the counter C1, and, in the event of reversing Pulley 5 of the countdown pulses on the counter C2 and counting pulses on the counter C1.
  • an encoder is maithe on the transmission of the corrugator, so that we know precisely, for the machine in question, the moment when the last plate of the first format leaves the cutter transverse 3 to fall on the carpet 1.
  • a gap has advantageously been created, by variation of their respective speeds, between the two sheets of cardboard corresponding to the two successive formats.
  • the format change operation on the receiver which can start at any time, including during a battery change, the retractable pulley 5 can have, at this time, any position, so that it is necessary to continuously operate the up-down counting device of Figure 5 coupled to the detector D3, even outside the format change operations.
  • the counting method is as follows:
  • the telescopic element carrying the pulley 5 is advanced as far as possible (position shown in FIG. 5).
  • the detector D3 gives pulses corresponding to the displacement of the pulley 5.
  • the pre-displays of the counters Cl and C2 are respectively the numbers NI, corresponding to L1, and N2, corresponding to L2.
  • the counter Cl mar 0 in counting, and the counter C2 marks in counting the number n corresponding to the length 1 of maximum retraction of the pulley 5.
  • the pulley 5 moves to the left, towards the maximum recoil position shown in dotted lines in 5 '.
  • the displacement pulses given by D3 are then counted on C1 and counted down on C2, so that at the position 5 ′ of maximum recoil, the comotor Cl will mark n and the counter C2 will mark 0.
  • the displacement pulses D3 will be counted down on Cl and counted on C2.
  • the sheet 19 has then passed through the conveyor 1 and falls on the conveyor 2. From the output 17 there comes a signal controlling the slowing down of the belt 1, the stop of the operation of the detector Dl, the triggering of the operation of the detector D2 whose pulses are also counted on the counter C2, and the stopping of any retraction of the pulley 5.
  • the sheet 19 has left the transfer generator 2, and the output 18 sends a signal controlling a battery change operation and the stop of the detector D2.
  • the front stop 16 changes position from the moment the lifting table 14 rises after having removed the last stack of the first format, the assembly resuming its normal operation until the next format change, where the cycle described above begins again a new time.
  • the invention finds its main use in the manufacture of corrugated cardboard plates.
