Definitions

  • the present invention relates to a transport system for load and unload of large flat items onto a process board such as a printer, which system comprises a transport board.
  • US 8459183 relates to a method of printing panel material with a printed image, whereby the panel material is moved from a feeding station into a printing station in which an image is applied and out of which it is fed onwards in the transport direction by means of a conveyor system.
  • the panel materials to be printed are disposed immediately one after the other in rows in the transport direction at least in an inlet region to the printing station and are fed jointly through the printing station during the print- ing operation, and the printed image is applied by means of an inkjet printing device.
  • the object of the pending patent application is to achieve automatic system for load and unload of large flat items in a full automatic and fast load and unload process.
  • a further object of the invention is to preform load and unload mostly simultaneously.
  • a further object of the invention is to turn an item upside down for double side processing.
  • the transport board comprises at least first loading cavity and second unloading handling cavity, which first loading cavity is formed between a plurality of first set of belts, which first set of belts are forces to move an item in the direction of the process board, which second unloading handling cavity is formed between a plurality of second set of belts, which second set of belts are forced to move an item away from the process board, which set of belts are forced to move by rotating wheels, which rotating wheels are rotated by motors, which motors are controlled by a control system, which transport board further comprises loading and unloading rollers.
  • Handling of different items is rather critical because fingerprints of the items are probably not acceptable in many situations, therefore personnel who has to perform the handling also has to wear gloves in order not to destroy the items. All in all it is a very time consuming process where for example the printer is in a standstill situation waiting to start the next process.
  • the pending application is able to solve these problems because the system as such is able to pick up and flat item at a storage and move the flat items towards the process board where probably a previous processing is taking place at an item.
  • the system at first picks up the item at the process board, but as soon as movement has started moving the item into a second cavity of the transport board, the transport board starts to load the next item at the process board. In that way the loading can take place extremely fast and the standstill period for example for a printer, a drilling machine or a grinding machine is extremely short.
  • the waiting time for the handling is only very few seconds. Further is achieved that no fingerprints have had any access to the item.
  • the loading and unloading rollers be are driven by motors controlled by the control system, which loading and unloading roller are carried at arms, which arms are forced to move around fixation means by actuators, which actuators are controlled by the control system.
  • the transport board can pick up items even if there is some distance to the item. Because the rollers are placed on arms, these arms can be turned around a bearing by an actuator so that the rollers can have access to the surface of the item.
  • the rollers By rotating the rollers, the item is moved in the direction of rotation of the rollers.
  • the item can be picked up and placed in one of the cavities where the belt that has the same direction of movement, further moves the item into the storage in the cavity.
  • the rollers are also active in moving the items the last few centimetres onto the board simply because the item at that moment has left the cavity and the belts. Therefore, the end movement maybe into a stop at a process board is made by the rollers. Direct position indication with help by the rollers is also possible. But the most direct position control is probably still a manual stop that the item is moved into contact with the stop. Further when the printed item is returned to a storage can, the rollers perform the last movement of the item at the storage so that an item is correct placed maybe on the top of other items at a storage. By correct dimension of rollers and arms and actuators an adjustment of the forces that are acting by the rollers at the items can be adjustable by a connected computer system.
  • the transport board be carried by a first vertical frame comprising actuator for vertical displacement.
  • actuator for vertical displacement Especially in relation to storage it is important that the transport board is able to change its vertical position.
  • the process board will have the same vertical position, but produc- ing a system that can be used for different purposes, it can also in relation to the production at the process board be important that the vertical distance can be changed easily, probably by the connected computer system.
  • the transport board and the first vertical frame be carried by a second horizontal frame, which vertical frame is moveable in at least one horizontal direction in relation to the second horizontal frame.
  • the system In many situations there will be some distance between storage and the process board. Therefore, it is rather important that the system as such is movable in horizontal direction. It is in some situations of course possible to place the storage so that only horizontal movement in one direction is necessary. But in other situations the system can be designed as a robot that is able to move at a floor in different directions.
  • the first set of belts be forced to move by rotating wheels, which second set of belts is forced to move by rotating wheels, which third set of belts are forced to move by rotating wheels.
  • the belts can be relative small for some possible embodiments for the inventions, but for other processes the belts can have a sufficient dimension so they are more or less filling the whole area and even in some situations only one very large belt can be used to fulfil requirements for very soft items to be sent to the processing.
  • a simple very small rubber belt can be used and in some situations there will be a high number of these parallel rubber belts. In the extreme situation to the other side there is simply one belt having the same size and the item. Therefore, this invention is able to handle a high number of different items. Starting with thin, solid plates up to very week material such as cloth, the same invention can probably be used.

Abstract

La présente invention porte sur un système de transport pour le chargement et le déchargement de grands articles plats (4) sur une plaque de traitement (6) telle qu'une imprimante, lequel système comprend une plaque de transport (8). La demande de brevet en instance vise à obtenir un système automatique pour le chargement et le déchargement de grands articles plats dans un processus de chargement et de déchargement rapide et entièrement automatique. À cet effet, selon l'invention, une plaque de transport comprend au moins une première cavité de chargement (10) et des deuxième cavités de déchargement (12) formées entre une pluralité d'ensembles de courroies. Il est ainsi obtenu que, par l'impression ou le traitement d'articles plats plus grands, la manipulation de ces éléments est très difficile, et que plusieurs personnes sont probablement impliquées à chaque fois qu'une manipulation manuelle doit être effectuée. Ceci est essentiel pour tous les traitements de plaques plates de grands articles. Spécialement dans des situations dans lesquelles de grands processus d'impression sont effectués, ou, dans des processus de perçage et de meulage qui demandent beaucoup de temps, ceci est très essentiel, car aucune personne ne peut observer le processus pendant l'opération. Par conséquent, quand le processus s'achève, il y a probablement un temps d'attente supplémentaire jusqu'à ce qu'éventuellement deux personnes soient prêtes pour changer un article.
