Description

La présente invention concerne une table de pliage, notamment d'une plieuse_équipée d'un dispositif de pli d'équerre, du type comprenant

  • une face de pliage qui est adaptée pour recevoir un produit plat à plier,
  • une fente de pliage s'étendant selon une direction d'acheminement, la table s'étendant suivant un plan de table.
The present invention relates to a folding table, in particular a folding machine equipped with a right-angle folding device, of the type comprising
  • a folding face which is adapted to receive a flat product to be folded,
  • a folding slot extending in a routing direction, the table extending in a table plane.

On connaît des dispositifs de pli d'équerre qui sont adaptés pour plier un produit plat, tel qu'une feuille ou une signature qui a été imprimée dans une presse rotative offset.Corner fold devices are known which are adapted to fold a flat product, such as a sheet or a signature which has been printed in an offset rotary press.

Ces dispositifs de pli d'équerre comportent une table de pliage, des rouleaux de pliage et une lame de pliage. La lame de pliage est utilisée pour pousser les produits plats à travers une fente ménagée dans la table dans un interstice formé par les rouleaux. Le dispositif de pli d'équerre est muni de courroies d'acheminement du produit plat afin de l'acheminer sur la table de pliage.These square fold devices include a folding table, folding rolls and a folding blade. The folding blade is used to push the flat products through a slot in the table in a gap formed by the rollers. The square bend device is provided with flat product conveyor belts for routing on the bending table.

Lors du pliage, les courroies d'acheminement sont entraînées par le produit à plier dans une direction transversale à leur direction d'acheminement. En conséquence, les courroies se chevauchent transversalement et créent des bourrages.During folding, the conveyor belts are driven by the product to be folded in a direction transverse to their direction of conveyance. As a result, the belts overlap transversely and create jams.

Le temps de disponibilité des dispositifs de pli d'équerre connus est donc faible.The availability time of the known angle fold devices is therefore low.

L'invention a pour but d'augmenter le temps de disponibilité d'un dispositif de pliage, notamment d'un dispositif de pli d'équerre.The object of the invention is to increase the time of availability of a folding device, in particular of a right-angle fold device.

A cet effet, l'invention a pour objet une table de pliage, notamment d'une plieuse équipée d'un dispositif de pli d'équerre, du type indiqué ci-dessus, caractérisée en ce que la face de pliage comporte des moyens de guidage adaptés pour guider un élément d'acheminement d'un produit plat à plier selon la direction d'acheminementFor this purpose, the object of the invention is a folding table, in particular a folding machine equipped with a square-fold device, of the type indicated above, characterized in that the folding face comprises means for guides adapted to guide a conveying element of a flat product to be folded according to the routing direction

D'autres aspects et avantages de l'invention apparaîtront au cours de la description qui suit, faite à titre d'exemple et en référence aux dessins annexés :

  • la Figure 1 est une vue en coupe d'un dispositif de pli d'équerre selon l'invention ;
  • la Figure 2 est une vue en perspective du dispositif de pli d'équerre selon l'invention, la lame de pliage étant omise ; et
  • la Figure 3 est une vue en coupe, à plus grande échelle d'une partie du dispositif de pli d'équerre selon l'invention.
Other aspects and advantages of the invention will become apparent from the description which follows, given by way of example and with reference to the appended drawings:
  • the Figure 1 is a sectional view of a square-fold device according to the invention;
  • the Figure 2 is a perspective view of the right-angle folding device according to the invention, the folding blade being omitted; and
  • the Figure 3 is a sectional view, on a larger scale of a portion of the angle fold device according to the invention.

Sur la Figure 1 est représentée en coupe un dispositif de pli d'équerre selon l'invention, désigné par la référence générale 2.On the Figure 1 is shown in section a right angle fold device according to the invention, designated by the general reference 2.

Le dispositif de pli d'équerre 2 comprend une table de pliage 4, une lame de pliage 6, et deux rouleaux de pliage 8, 10.The square folding device 2 comprises a folding table 4, a folding blade 6, and two folding rollers 8, 10.

La lame de pliage 6 est mobile en va-et-vient selon une direction de pliage DP et est disposé sur un côté de la table de pliage 4. Les deux rouleaux de pliage 8, 10 ont des axes parallèles et forment un interstice de pliage entre eux.The folding blade 6 is movable back and forth in a folding direction DP and is arranged on one side of the folding table 4. The two folding rollers 8, 10 have parallel axes and form a folding interstice between them.

Le dispositif de pli d'équerre 2 comporte des courroies de convoyage inférieures 12 et des courroies de convoyage supérieures 14. Les courroies de convoyage 12 et 14 sont adaptées pour acheminer des produits plats à plier 16, tels que des signatures ou des feuilles, sur la table de pliage 4 selon une direction d'acheminement D et selon un sens d'acheminement S (voir Figure 2). A cet effet, les courroies de convoyage 12 et 14 s'étendent parallèlement par rapport à la direction d'acheminement D et sont entraînées selon le sens d'acheminement S.The square crease device 2 comprises lower conveyor belts 12 and upper conveyor belts 14. The conveyor belts 12 and 14 are adapted for conveying flat products to be folded 16, such as signatures or sheets, onto the folding table 4 according to a direction of routing D and in a direction of routing S (see Figure 2 ). For this purpose, the conveyor belts 12 and 14 extend parallel to the conveying direction D and are driven in the direction of conveyance S.

La table de pliage 4 comporte une face de pliage 18, tournée vers la lame de pliage 6, et une face inférieure 20, dirigée vers les rouleaux de pliage 8, 10.The folding table 4 has a folding face 18 facing the folding blade 6 and a lower face 20 facing the folding rollers 8, 10.

La table de pliage 4 délimite une fente de pliage 22 à travers laquelle les produits à plier 16 sont poussées par la lame 6. La fente de pliage 22 s'étend parallèlement à la direction d'acheminement D.The folding table 4 defines a folding slot 22 through which the products to be folded 16 are pushed by the blade 6. The folding slot 22 extends parallel to the routing direction D.

La table de pliage 4 est munie de moyens de guidage 24 des courroies de convoyage inférieures 12 selon la direction d'acheminement D. Ces moyens de guidage 24 sont adaptés pour s'opposer à une déviation des courroies de convoyage inférieures 12 vers la fente de pliage 22 , donc transversalement à la direction D, lorsque le produit à plier 16 est poussé par la lame de pliage 6 à travers la fente de pliage 22.The folding table 4 is provided with means 24 for guiding the lower conveyor belts 12 in the conveying direction D. These guide means 24 are adapted to oppose a deflection of the lower conveyor belts 12 towards the slot of the conveyor. folding 22, therefore transversely to the direction D, when the product to be folded 16 is pushed by the folding blade 6 through the folding slot 22.

A cet effet, la table de pliage 4 comporte un corps de base 26 et des nervures de guidage 28 s'étendant selon la direction d'acheminement D.For this purpose, the folding table 4 comprises a base body 26 and guide ribs 28 extending in the direction of routing D.

Le corps de base 26 a une forme générale de parallélépipède. Les nervures 28 sont disposées sur le corps de base 26 et forment les moyens de guidage 24.The base body 26 has a general parallelepiped shape. The ribs 28 are arranged on the base body 26 and form the guide means 24.

Les nervures 28 et le corps de base 26 forment la face de pliage 18.The ribs 28 and the base body 26 form the folding face 18.

Deux nervures de guidage 28 adjacentes forment entre elles un canal de guidage 30 (voir Figure 3) dans lequel s'étend soit une courroie de convoyage inférieure 12, soit plusieurs courroies de convoyage inférieures 12. Par ailleurs, le canal de convoyage 30 le plus près de la fente de pliage 22 reçoit deux courroies de convoyage inférieures 12. Les deux courroies de convoyage 12 dans le même canal de convoyage, de part et d'autre de la lame de pli 6, sont utilisées pour un meilleur guidage et un meilleur maintient lors de la phase de pli, des cahiers, des signatures, des feuilles, notamment de faible largeur (bande de papier de petite laize).Two adjacent guide ribs 28 form between them a guide channel 30 (see FIG. Figure 3 ) in which extends either a lower conveyor belt 12 or several lower conveyor belts 12. Furthermore, the conveying channel 30 closest to the folding slot 22 receives two lower conveyor belts 12. The two belts conveying 12 in the same conveying channel, on both sides of the fold blade 6, are used for better guidance and better maintenance during the fold phase, notebooks, signatures, sheets, in particular narrow width (small width paper strip).

Chaque nervure de guidage 28 est ainsi disposée entre la courroie de convoyage inférieure 12 associée et la fente de pliage 22 afin de pouvoir guider la courroie 12 lors du pliage.Each guide rib 28 is thus arranged between the associated lower conveyor belt 12 and the folding slot 22 so as to guide the belt 12 during folding.

Les courroies de convoyage inférieures 12 ont une première hauteur H1, mesurée perpendiculairement au plan de table P, et chaque nervure de guidage 28 a une deuxième hauteur H2, également mesurée perpendiculairement au plan P de la table. Avantageusement, la deuxième hauteur H2 est soit inférieure ou identique ou soit strictement inférieure à la hauteur H1 afin de ne pas perturber le pliage du produit à plier 16. En particulier, la nervure de guidage 28 a une hauteur H2 qui est comprise entre 0,5 et 0,8 fois la première hauteur H1, et contribue ainsi à supporter le produit à plier 16 lors de l'acheminement.The lower conveyor belts 12 have a first height H1, measured perpendicular to the table plane P, and each guide rib 28 has a second height H2, also measured perpendicularly to the plane P of the table. Advantageously, the second height H2 is either less or identical or is strictly less than the height H1 so as not to disturb the folding of the product to be folded. In particular, the guide rib 28 has a height H2 which is between 0, 5 and 0.8 times the first height H1, and thus contributes to supporting the product to bend 16 during the routing.

Par ailleurs, le corps de base 26 et les nervures 28 sont munies d'un revêtement anti-frottement 32, qui est avantageusement fabriqué en chrome. Ce revêtement 32 favorise le glissement des courroies de convoyage 12 et des produits à plier sur la table 4.Furthermore, the base body 26 and the ribs 28 are provided with an anti-friction coating 32, which is advantageously made of chromium. This coating 32 promotes the sliding of the conveyor belts 12 and the products to be folded on the table 4.

Il est à noter, qu'en cas de la présence du revêtement 32, la deuxième hauteur H2 est mesurée de la surface libre du revêtement 32 du corps de base 26 à la surface libre du revêtement 32 de la nervure 28.It should be noted that in the case of the presence of the coating 32, the second height H2 is measured from the free surface of the coating 32 of the base body 26 to the free surface of the coating 32 of the rib 28.

Egalement, les nervures de guidage 28 sont fabriquées d'un seul tenant et notamment d'une seule pièce avec le corps de base 26, ce qui réduit les coûts de fabrication du dispositif de pliage.Also, the guide ribs 28 are made in one piece and in particular in one piece with the base body 26, which reduces the manufacturing costs of the folding device.

Le corps de base 26 et les nervures 28 sont fabriqués par exemple en acier ou en aluminium.The base body 26 and the ribs 28 are made for example of steel or aluminum.

La table de pliage selon l'invention réduit avec des moyens simples et économiques le risque de bourrage des plieuses d'équerre et augmente ainsi la fiabilité de la plieuse.The folding table according to the invention reduces with simple and economical means the risk of jamming of the bending machines and thus increases the reliability of the folder.

Il est à noter que les courroies de convoyage 12, 14 peuvent être remplacées par d'autres éléments d'acheminement.It should be noted that the conveyor belts 12, 14 can be replaced by other conveying elements.
