Abstract

Automation of a cylindrical bailing press. The object of the invention is to automate the triggering of the various stages of forming a cylindrical bail in a variable-chamber or constant-chamber bailing press. Contrary to the prior art where bailing presses did not operate continuously, the bail, in the system in accordance with the invention, itself triggers the functions in series by virtue of an automation box; binding, stopping the belts, opening the gate 5, ejecting the bail 8 after starting the belts, closing the gate and raising the table 6. The hydraulic opening of the gate takes place upwards whilst the carrying table 6, which is very much raised towards the rear, comes down towards the bottom at the same time as the gate. The hydraulic opening and closing of the gate are independent of the tractor.

Description

AUTOMATISATION D'UNE PRESSE A BALLE CYLIMDRI@UE
Le but de l'inyention est de rendre automatique les différentes fonctions d'une presse à balle cylindrique, qu'elle soit concue à chambre variable ou à chambre constante.AUTOMATION OF A CYLIMDRI @ UE BALL PRESS
The purpose of the invention is to make the various functions of a cylindrical baler automatic, whether designed with a variable chamber or with a constant chamber.

Les Dresses à balle cylindrioue actuelles ne travaillent en continu, donc chaque fonction est faite par le chauffeur du tracteur, ler reculer, 2e liage, ( électrique ou hydrolique ), 3e arret des courroies pour ouverture de la porte, 4e ouverture de la porte, 5e embrayage des courroies pour éjection de la balle, 6e avancer le tracteur pour pouvoir fermer la porte, 7e fermeture de la porte. Toutes ces fonctions sont des pertes de temps et demande une grande expérience de la part du chauffeur.The current cylindrical ball dresses do not work continuously, so each function is performed by the tractor driver, backing up, 2nd tying, (electric or hydraulic), 3rd stop of the belts for opening the door, 4th opening of the door, 5th clutch of the belts to eject the bale, 6th move the tractor forward to be able to close the door, 7th close the door. All these functions are a waste of time and require a great deal of experience on the part of the driver.

L?inovation permet à la balle qui est terminée dans la presse de déclen- cher elle-même toutes les fonctions en série. A sa grosseur normale, la balle arrête le pick Up et déclenche le liage ( pour gagner du temps on pourra doubler les lieurs pour qu'ils ne fassent qu'un seul passage ). La liage terminé les lieurs dëclenchent ( par l'intermédiaire du boîtier d'automatisation ) l'arrêt des courroies et l'ouverture de la porte par l'hydraqulique indépendant du tracteur . Loi, on note une inovation très importante par rapport aux autres presses existantes et nécessaire à l'automatisation. Le tablier porteur de la balle est très relevé vers l'arrière et celui-ci s'abaisse en même temps que s'ouvre la porte vers le haut. Cette inovation indispensable et unique en son genre, permet sans avancer le passage de la porte devant la balle qui est posée au sol. The innovation allows the bale which is finished in the press to trigger all the functions in series. At its normal size, the ball stops the pick up and triggers the binding (to save time we can double the linkers so that they make only one pass). When the tying is finished, the linkers trigger (via the automation unit) the stopping of the belts and the opening of the door by the hydraulic system independent of the tractor. Law, there is a very important innovation compared to other existing presses and necessary for automation. The bale-carrying apron is very raised towards the rear and this is lowered at the same time as the door opens upwards. This essential and one-of-a-kind inovation allows without advancing the passage of the door in front of the ball which is placed on the ground.

La fermeture de la porte déclenche la mise en route du pick up Un signal lumineux ou sonere averti le chauffeur qu'il peut repartir. When the door is closed, the pick-up starts. A light or sound signal warns the driver that he can leave.

Claims

CLAIM

The automation case 1 makes it possible to centralize the functions and order the following cycles.

Cycle A t A @ stop of the pick up by contact 2 confirm by the size of the bale 8 and start of cycle B

Cycle B: Binding of the hydraulic or electric boot, the linker may also double 3 to reduce the binding time (string number 10). The end of the binding triggers the cycle C.

Cycle C: Stopping of the belts by the coupling 4, the main shaft 9 always turns as well as the independent hydraulic pump 7. The open clutch controls the start of cycle D.

Cycle D X Opening of door 5 upwards and of the support apron 6 towards the bottom. This inovation of the descending apron, as well as the shape of the door, is new in their design, and essential for closing it without advancing the press. Once the door is open and the door folded down start of cycle E.

Cycle E: Starting of the belts by gluing the clutch 4 in order to eject the bale 8. Once the bale ejected, start of cycle F.

Cycle F: Closing of the door and raising of the apron, The belts always rotate. The opening and closing of the door are hydraulic, this hydraulic is independent of the tractor by a linked pump mounted on the main shaft 9, it always turns whatever the function. When the door is completely closed, an audible or light signal is given to warn the driver that he can leave.
