If the control device 86 measures an actual load of the main motor 80 over an adjustable period of time, which is / greater than a predefinable target load, the reason for this can be in a contact pressure of the pressing jaws 8 that is too high, for example, for hardwood present in the form of fine chips and 10 are. The control device then emits a signal which lowers the signal pressure in the pressure cylinders 58 and 60, for example to the pressure control valve 85 (FIG. 3). which is connected between the pressure medium source and the pressure cylinders. This relieves the main engine. The pressure level is monitored by the control device 86, if necessary and also compared with a setpoint. The load on the main motor and, if applicable, the pressure in the pressure cylinders is adjusted to the setpoints.

  • the control device 86 additionally sends a control signal to the transmission
  • the target load of the main engine cannot be reached, which reduces the speed and thus reduces the amount of material supplied, which relieves the main engine and allows it to run again within the target load range. 2. If, for example, in the case of softwood in the form of coarse chips, the load on the main motor falls below the desired value, the pressing pressure exerted on the pressing jaws can first be increased to a maximum value by increasing the signal pressure in the pressure cylinders. If the target load is not yet reached, the control device outputs a control signal to the geared motor, by which the speed of the geared motor 82 is increased until the main motor 80 runs again with the target load.
  • the regulation of the load on the main motor additionally via the speed of the geared motor of the feed device does not of course need to start until the signal pressure of the pressure cylinder reaches the maximum and minimum values that can be specified, but can also be used for any signal pressure values that lie between the maximum and minimum. respectively.

  • the speed control is designed in such a way that it is readjusted up to a predefinable target load. This enables optimal utilization of both the main motor and the gear motor.
  • the respective limit values for the signal pressure can be determined by the end positions of the press jaws that are scanned.
  • the load on the main motor can be monitored by measuring the current consumption with averaging.
  • the speed of the geared motor can be measured using the known rotary encoders.

If the wedge angle cannot be selected accordingly or if such an automatic return movement should not take place due to additional frictional forces, return springs 75 and 77 moving back the frame can additionally be provided, cf.

Abstract

Presse à briquettes avec mâchoires de pressage (8, 10) en partie de cylindre; procédé et installation pour régler la puissance de pression. Le but de la présente invention est de développer une presse à briquettes de telle façon que la puissance de pression puisse être réglée rapidement et automatiquement en fonction des propriétés du matériau à comprimer, afin d'éviter des surcharges de lapresse et d'obtenir des briquettes de qualités constantes. A cet effet, les mâchoires de pressage (8, 10) sont réglables par l'intermédiaire d'une installation manoeuvrable exerçant des forces de coin. Cette installation possède des surfaces de coin (44, 46) formées sur les mâchoires de pressage, sur lesquelles se déplacent des rouleaux de pression (48, 50) disposés dans un cadre mobile (52). Afin de régler la puissance de pression, on mesure la charge du moteur à piston de compression (80) que l'on compare avec une valeur seuil. Lorsqu'elle s'écarte de la valeur seuil, on modifie la puissance de pression des mâchoires de pressage (8, 10) et/ou la quantité de matériau amené, de manière à régler le moteur à piston de compression (80) à la charge seuil.
