DETAILED DESCRIPTION OF THE INVENTION

(5) The invention relates to a high-speed cornet bending machine (A) with high production capacity and mechanically independent motion control system.

(6) As shown in FIG. 1, the bending machine (A) according to the invention comprises a main body (13) which carries the elements forming the bending machine (A). On the main body (13), there is at least one feeding magazine (1) which sequentially transfers the papers to the conveying apparatus (2). The driving movement of said feeding magazine (1) is provided by the feeder motors (3). In front of the feeding magazine (1), the conveying belt (2) which is conveyed from the feeding apparatus (1) to the transfer line (5) is positioned. Said transfer line (5) transfers the papers from the transport apparatus (2) to the end bending unit (8) as standard. The sliding device 4 transfers the papers from the feeding magazine 1 to the transport apparatuses 2.

(7) As seen in FIG. 1, the cornet bending machine A according to the invention comprises at least one saw blade 6 which cuts off the excess pieces on the paper going from the transfer line 5 to the end curling unit 8. When the cornet bending machine (A) stops next to the saw blade (6), the operator cuts the saw blade (6) from the end bending unit (8) at least one blade swivel (7) for preventing accidents is located.

(8) As shown in FIG. 1, the cornet bender (A) according to the invention comprises a tip crimp unit (8) which allows the product ends to be crimped in a standard manner. On the sides of the end bending unit (8) are end bending motors (9) which allow the end bending unit (8) of the paper to enter smoothly.

(9) As shown in FIG. 2, said end bending unit 8 is provided with an upper bending conical mold 8.1 for providing vacuum removal of the sheets from the transfer line 5 and an upper bending bushing mold 8 located under the upper bending conical mold 8.1, (8.2) which folds the paper together with the upper bending conical mold (8.1). The upper bending conical mold (8.1) gives the drive action the upper bending drive motor (8.3). The lower bending conical mold (8.2) gives the drive motion to the lower bending drive motor (8.4). Behind the upper curving conical mold (8.1) is the opening and closing motor (8.5) which allows the upper curving conical mold (8.1) to open and close. Beneath the chip blade (6), a chip suction unit (16) is located which allows the excess chips cut by the chip knife (6) to be sucked and discharged from the medium.

(10) As shown in FIG. 1, the cornet bending machine subject to intervention (A) comprises a glue tank (10) which provides adhesion of the molten glue product. The glue injectors (11) allow the glue coming from the glue tank (10) to be driven onto the paper. Semi lunar reels (12) allow the sheets coming from the feeding magazine (1) to be driven to the transfer line (5).

(11) As shown in FIG. 1, the cornet bender A according to the invention includes feed sensors 14 for starting the feed by sensing the position of the semi lunar reel 12 relative to the product and signaling the appropriate position. The paper transfer unit 15 located on the main body 13 transfers the paper from the transfer line 4 to the end bending unit by equally spacing the paper at a certain distance. The carrier feet (15.1) on the paper transfer unit (15) ensure that the papers are evenly spaced at a certain distance. The paper transfer unit (15) is positioned at an angle of at least 1 degree relative to the floor. In this way, the climbing motion is given to the products and the product transfer is carried out at higher speeds by preventing the undesired movement of the positioned products.

(12) In accordance with the above information, the coating machine (A) according to the present invention operates in the following manner.

(13) As shown in FIG. 1, the loading operation is carried out by the operator to the conveying apparatus 2 in such a manner that the cornet papers in the semi-finished state of the feed magazine 1 are overlaid. The products from the conveying apparatus 2 are removed one by one and conveyed in the fastest manner to the feed sensors 14 by means of the conveyor apparatus 4 on the feeding magazine 1 and held until the appropriate time information from the feed sensor 14 is received. When appropriate information is received, the product is transferred to the feed sensor (14). The semi lunar reel (12) on the transfer line (5) specified as the appropriate time information is the position relative to the product. Products are transferred to the paper transfer unit (15) by the semi lunar reel (12). The carrier feet (15.1) on the paper transfer unit (15) start conveying the products at a certain distance to the end bending unit (8) by aligning the end bending unit (8) During this transfer process, the products are positioned relative to the transfer line (5) with the upper curling conical mold (8.1) and the lower curling conical mold (8.2).

(14) Gluing is carried out with the glue injector (11) in the interior of the products with the desired properties immediately before entering the end bending unit (8) in the products positioned and located in the vicinity of the end bending unit (8). Then the products coming in front of the end bending unit 8 are vacuumed by the upper bending conical mold 8.1 and the products received on the paper transfer unit 15 are compressed with the lower bending conical die 8.2 and bended at the same time by bending. During this bending operation, the upper overrunning drive motor (8.3) is provided. The lower bending conical mold (8.2) gives the drive motion to the lower bending drive motor (8.4). During this bending process, the excess chips formed in the mouth portion of the product are cut with the saw blade (6) rotating on the upper bending conical mold (8.1). Cut chips are sucked out by the chip suction unit (16). After the bending process and the chip cutting process are completed, the lower bending conical mold (8.2) is opened by the opening/closing motor (8.5) and the upper bending conical mold (8.1) In this way the production cycle is repeated continuously. The products are collected manually by the operator in the collection chamber.

(15) In the cornet bending machine (A) of the invention, there are preferably two end bending units (8). In this way, the production speed is increased. The end bending units (8) on the cornet bending machine (A) operate independently of each other. In an alternative embodiment of the invention, the cornet bending machine (A) may have one or more multi-end bending units (8).
