Definitions

  • the present invention relates to an installation for the continuous production of various mineral fiber products, consisting of a plurality of devices, most of which are provided with elements for adjusting the parameters specific to the product produced.
  • Such an installation for the manufacture of mineral fiber products usually referred to as a production line, consists, from the fiberizing station to the packaging station, of several devices which act on the mineral fiber product with a view for example to '' add binder, compress it, harden it, cut it in width, cut it in length, cover it if necessary with a facing, roll it up, stack it, l 'to wrap up.
  • a production line is described for example in document DE-OS-3 100 003; the problems relating to the application of a facing on such mineral fiber products are more particularly explained in documents DE-OS-3 036 816 and 3 325 341 while those relating to the control of a winding station at the end of the production line are in document DE-OS-3 314 289.
  • Such heights differing from one case to another can again influence subsequent processing operations, for example the winding operation as such, the length of ply necessary for the wrapping path of the roll, etc., being It is understood that other quantities which also vary according to the circumstances can again intervene here, such as for example the binder content.
  • the installation comprises a certain number of adjustment elements provided on apparatuses of the installation for adjusting parameters specific to the product, said parameters being able to be adjusted by hand on set point adjustment devices. and be applied to the adjustment elements by means of an electrical control signal produced in each setpoint adjusting device, the electrical control signals being stored in a read only memory and stored as setpoints under a common address corresponding to a product determined to be manufactured; said set values being extracted jointly, by calling the address, and being applied as control signals to the adjustment elements, and the novelty is that the control signals can be modified momentarily in a pre-established domain, without modifying the stored setpoints, by means of manual correction devices.
  • the line Since a product is to be produced for the first time on the line, the line is controlled by hand by highly quality personnel who select likely settings and change parameters during a test cycle in such a way that a desired product quality is obtained.
  • the setpoint adjustment devices are used as simple control elements by means of which rapid variations in the setting can be carried out and monitored by qualified personnel, in order to achieve individual combinations of the chain. the desired product quality.
  • the settings thus acquired are taken over as setpoints in the ROM and are stored as data associated with the product. They can in this way be called at any time via the specific address of the product, in common for all devices.
  • the setpoints can be adjusted at the setpoint adjusters to an average value, if necessary by corresponding subsequent corrections made by highly qualified personnel, for example after a relatively long operation of the line with the new product, this average value giving, in the case of the desired product, a quality of product in any case still acceptable taking into account the amplitude of the variations of the parameters to be taken into account which presents itself.
  • less qualified personnel can also call these average values together, at the press of a button, after they have been stored in the fixed memory, so that the transition from the entire production line to these values pre-determined takes place automatically without an Interruption of production or that significant quantities of scrap are produced.
  • the quality of the product obtained on the basis of the newly called set values may however from one case to another not be optimal, although still suitable for sale, and may furthermore change little little by little during production.
  • correction manipulations are planned and also allow less qualified personnel to make corresponding adjustments.
  • This possibility of adjustment is however situated in a predetermined framework which certainly excludes gross adjustment errors.
  • the adjustments are not introduced into the fixed memory and therefore do not modify the set value therein that this set value remains always available without modification. This guarantees that with the aid of the adjustment in a determined framework, optimizations can be carried out, the basic adjustment for the product remaining however always available in accordance with the storage in the fixed memory. In this way, additive errors are avoided with certainty which would otherwise be inevitable in the case of multiple adjustments and corresponding storage of the values each time adjusted, in particular with low-skilled personnel.
  • the single figure of the drawing is a simplified schematic view and presenting itself as a mounting diagram of an installation according to the invention in the area of a winding station.
  • 1 designates a winding station as described in more detail, for example, in document DE-OS-3 314 289, to which reference is explicitly made.
  • a winding station As explained precisely in this document, during the winding and wrapping of the sheets of mineral fibers in such a winding station, it is necessary to carry out numerous control operations and to fine-tune them together to obtain a quality optimal product. Similar control operations as well as a reciprocal agreement of set parameters must be carried out during previous work operations of such a production line, and in this regard, with regard to the problems posed by the application of a facing, reference should be made to documents DE-OS-30 816 and 3 325 341 to which reference is explicitly made for other details.
  • a sheet of mineral fibers 3 is brought by its front end to a conveyor belt 4 in the winding station 1, where the front end of the mineral fiber sheet 3 is returned by a straightening strip 5 and forms a coil 6.
  • the carding roller 2 guides the curved front end of the mineral fiber sheet 3 to form the first turn and is then applied under a defined pressure against the external face of the coil 6 which forms and whose diameter increases, to regulate the pressure exerted on the turns and thus influence the final diameter of the formed coil.
  • the application pressure of the carding roller 2 on the periphery of the coil 6 is adjusted by means of a jack 7, for example a pneumatic jack.
  • the cylinder is supplied with pressurized agent through a line 8 from a source of pressurized agent, not shown here, the pressurized agent line 8 containing a control member 9 which regulates the pressure of the agent under pressure in the cylinder 7.
  • the adjustment of the control member 9 is carried out by means of an adjustment element of a central control unit, abbreviated to CPU, designated at 11.
  • a probing line 12 is connected to the pressurized agent 8 and transmits the effective pressure of the pressurized agent, present in line 8, to a feeler 13 in the form of a measurement transducer, which applies an electrical comparison signal via a power line 14 to the CPU 11, so that a control circuit generally designated at 15 is formed and ensures that the actual value of the pressure in the cylinder 7 actually corresponds to the value which is set by the CPU 11 on the adjustment element 10.
  • the setting value for element 10 can be adjusted by hand on a setpoint adjusting device 16 connected via electrical lines 17 and 18 having an intermediate inverter 19 to the CPU 11 in such a way that 'A direct adjustment of the adjustment element 10 corresponding to the reference value adjustment 16 is obtained.
  • the personnel can directly modify the pressure in the jack 7 and thus regulate the action of the carding roller 2 on the reel 6 in the desired manner.
  • the CPU 11 supplies, in addition to the adjusting element 10, several other adjusting elements 20, for example in the area of the winding station 1 or in other areas of the line of production by means of corresponding adjustment data which is each time introduced by associated setpoint adjustment devices 16.
  • each desired parameter of the production line can be adjusted to a selected value by means of an associated setpoint adjustment device 16, the CPU 11 or several central units of this kind and corresponding adjustment elements.
  • the production line can thus be adjusted so that it gives an optimal product quality.
  • average values are introduced into the setpoint adjustment devices 16 which allow deviations on both sides as much as possible without leading to the production of scrap.
  • a manual correction device 25 to each setting device the setpoint 16 which is connected to the CPU 11 instead of the corresponding setpoint setting device 16, when switching from manual operation by means of the setpoint adjustment device 16 for automatic operation by means of read-only memory 22, the inverter 19 connecting instead of line 17, a corresponding line 26 of the manual correction device 25 to the input line 18 of the CPU 11.
  • the manual correction device 25 allows fine adjustment between preset limits, the control or control signal that the CPU 11 applies to each control element 10 or 20 in a manner corresponding to the storage in the memory. fixed 22.
  • the manual correction devices 25 only modify the signal and not the average value stored independently of it in the read-only memory 22, which can only be modified by pressing the key 21.
  • This final state is checked by the manager and is memorized by pressing the key 21 in the read-only memory 22 in which it is stored under the address of the new product.
