  • the present invention relates to a computerized control device and a computer-implemented method for controlling the speed of a conveyor for feeding printed products to stacking devices which form packages of printed products.
  • EP 1 935 821 describes a method for stacking printed products in a production line, in which the process for collating the printed sheets into precursors is controlled as a function of the stack size to be formed. According to EP 1 935 821, based on the cycle time for the discharge of a stack and the number of cycles with which the production line is produced, a minimum number of cycles is calculated which the stacking devices need for the formation of a stack. If particularly small stacks with a smaller number of cycles must be formed, in the production line according to EP 1 935 821 empty cycles are inserted, which reduces the production capacity of the production line.
  • an allocation plan for the stacking devices is guided with products attached to one of the Stacking devices upstream detection point were detected on the conveyor and can be processed at a defined target speed of the conveyor by an associated stacking device.
  • the desired speed of the conveyor is automatically reduced if in the allocation plan for at least one product no destacking can be determined, which can process the at least one product at the unreduced target speed of the conveyor, that is, if the product concerned in the allocation plan not one of the stacking so assigned can be that it is processable at the unreduced target speed of the conveyor.
  • a product is preferably determined based on the current position of the particular product based on the processing speeds of the stacking devices based on the desired speed of the conveyor and based on the allocation of products to each of the stacking devices in the allocation plan which of the stacking devices the product in question can be processed at the defined target speed of the conveyor.
  • the current position of a product on the conveyor defines its respective relative position or distance to the inputs of the stacking devices.
  • a current position on the conveyor or in the associated stacking device is respectively determined for the products included in the allocation plan, and the setpoint speed of the conveyor is increased if a product that has caused a reduction of the setpoint speed of the conveyor, a defined position (in the Printed product processing plant) has reached.
  • the desired speed of the conveyor is increased, for example, when the product, which has justified a reduction in the desired speed of the conveyor has reached the trigger point for transfer to the associated stacking device, or at this point already triggered and handed over to the stacking device, or before Stacking device has been processed.
  • the determination of whether and by which of the stacking devices the products transported on the conveyor can be processed at the defined target speed of the conveyor, and the virtual allocation of the products based on the individual stacking devices enables an automatic, dynamic and flexible adaptation of the conveyor speed to production-specific parameters and Conditions such as product thickness, package size, number of products in the package, package structure, and availability and processing speed of stacking devices, avoiding overflow of non-processable products as much as possible and keeping production output (ie products / time) as high as possible.
  • this dynamic adaptation of the conveying speed allows a high degree of flexibility in the package formation with individually different and time-varying package sizes in the individual stacking devices.
  • the current conveying speed of the conveyor is set to the target speed at a defined time, and in the allocation plan, a product is assigned to one of the stacking devices, if the relevant product at a set from the defined time to the reduced target speed conveyor speed by the relevant Stacking device is processable.
  • the time for setting the current conveying speed of the conveyor to the reduced set speed is set as late as possible in such a way that the relevant product can still be processed by the corresponding stacking device in question.
  • the longest possible delay of a speed reduction has the advantage that the conveying speed and thus the operating performance is kept as high as possible, while the processability of the products is granted and the overflow of products is avoided.
  • the current conveying speed of the conveyor is set to the setpoint speed at periodic times.
  • the period of time for possibly adjusting the conveying speed to a reduced or increased set speed is preferably a multiple of the time duration in which two successive products on the conveyor pass a fixed reference point, for example the detection point.
  • the products detected in the allocation plan, which are still on the conveyor are each assigned to one of the stacking devices, which can process the product in question at the reduced setpoint speed of the conveyor when the setpoint speed of the conveyor is reduced.
  • the reallocation of the unreleased and non-overflow products at each speed reduction allows for the continuous automatic optimization of production planning and execution by way of a processable allocation of the products to the stackers dynamically adapted to the conveying speed.
  • the present invention also relates to a computer program product comprising a computer-readable storage medium having stored therein
  • Computer code includes.
  • the computer code is arranged to control one or more processors of the control device in such a way that the processors or the control device for the stacking devices carry out an allocation plan with products which were detected at a detection point upstream of the stacking devices on the conveyor and at a defined desired speed of the conveyor each associated Abstapelvoriques are processable, and that the processors and the control device reduce the target speed of the conveyor, if at least one product in the allocation plan can not be assigned to one of the stacking devices so that it can be processed at the unreduced nominal speed of the conveyor.

Abstract

L'invention concerne un dispositif de commande et un procédé pour réguler la vitesse d'un convoyeur. Selon l'invention, la régulation de la vitesse d'un convoyeur (2) destiné à transporter des produits imprimés vers des dispositifs d'empilage (A, B, C) est réalisée en menant pour les dispositifs d'empilage (A, B, C) un plan d'allocation (Z) des produits (P, P*) qui ont été détectés sur le convoyeur (2) au niveau de l'un des points de détection (DD) placés en amont des dispositifs d'empilage (A, B, C) et qui peuvent être traités avec une vitesse de consigne donnée (55) du convoyeur (2) à chaque fois par un dispositif d'empilage (A, B, C) associé. La vitesse de consigne (55) du convoyeur (2) est réduite automatiquement lorsqu'au moins un produit détecté (P, P*) ne peut pas, dans le plan d'allocation (Z), être associé à l'un des dispositifs d'empilage (A, B, C) de manière à pouvoir être traité à la vitesse de consigne (55) non réduite du convoyeur (2). La détermination de la possibilité de traitement d'un produit (P, P*) à la vitesse de consigne (55) et, le cas échéant, par quel dispositif d'empilage (A, B, C), ainsi que l'allocation virtuelle des produits (P, P*) à chaque fois à l'un des dispositifs d'empilage (A, B, C) basée là-dessus permet une adaptation automatique, dynamique et flexible de la vitesse de convoyage à des paramètres et des états spécifiques à la production. Selon l'invention, la capacité de production est maintenue la plus élevée possible.
