Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides a transfer passage for supplying book blocks to a grasping and conveying device of a perfect binding machine, and a paper feeding device for separately separating endpapers and supplying them to the passage. Is it in the transport passageway? E?
5. The first and last of the book blocks having individual endpaper passageways, transport elements that grab the book blocks and endpapers and feed them together into a conveying device, and glue application discs for gluing the endpapers to the first and last folds. The present invention relates to a endpaper adhesive device for a perfect binding machine that positions endpapers on signatures and adheres them laterally.

[Conventional technology]

DE 29 48 802 A1 describes a device for positioning and laterally gluing endpapers on the first and last signatures of a book block in the transport path of a perfect binding machine. In this device, the endpapers are separated by a rotary paper feeder provided on the l side and fed into a U-shaped endpaper path having guide means at the top, located at a distance from the transport path. The transfer of book blocks and both endpapers in the transfer aisle and both endpaper aisles is carried out as follows:
This is done by a feed chain with feed fingers.

The book block is coated with a band of glue using a glue nozzle on the outer part of the edge cut, and then the supplied endpaper is integrated into the block by means of a suppression element. The book block is then passed in a clamped state through a glue applicator for applying glue to the endpaper edges, which is provided with mutually inclined conical applicator rollers for applying glue to the book block edges; Glue is thus pressed between the first and last signature and each endpaper.

This requires a very large construction outlay and does not result in a glue application with a linear progression in .

Furthermore, German Patent Application No. 1 536 512 discloses that a device for attaching endpapers to the first and last signatures of a book block in a perfect binding machine is provided with a suction device that lifts endpapers from the book block provided on the side of a gripping and conveying device. The element is described with a glue application disc that applies glue in a band to the endpaper. Further, on the above publication, the endpaper is slightly lifted laterally from the book block by a suction roller, and a band of glue is applied to the first and last sheets of the book block using a glue wheel similar to that of a endpaper gluer. It is also stated that this is possible.

As is known, suction rollers or similar suction elements are used to ensure that the endpapers are unrolled from the book block held by the clips of a perfect binder only when the speed of passage of the book block is relatively slow. Can be done.

Since the return force of the endpaper protruding at a small distance from the clip is large, it is not guaranteed that the endpaper can be reliably grasped and lifted from one book block when efficiency is increased.

[Problem to be solved by the invention]

An object of the present invention is to provide an endpaper gluing device for a perfect binder, which is capable of applying glue evenly and linearly in order to improve quality. Furthermore, this facing gluing device should be characterized by a high degree of reliable functionality, especially at very high working speeds, without having the above-mentioned disadvantages of known devices.

[Means to solve the problem]

A transfer path is provided for feeding the book blocks to the gripping and conveying device of the perfect binder, and a paper feeding device is provided for separately feeding endpapers into the path. Transfer path K G 5 - 1 book block with individual endpaper paths, transport elements that grab the book block and endpapers and send them together to the transport device, and a glue application disc for gluing the endpapers to the first and last signatures. Starting from the endpaper gluing device of a perfect binding machine, which positions and laterally glues the endpapers on the first and last signatures of the position, and in this final position area K, a glue application disc is provided, which applies glue from below in a linear manner to the part near the spine of the endpaper bent by the endpaper passageway. Therefore, the glue applicator disk is fitted into the facing channel, in which case the glue application disc is provided with an application surface inclined correspondingly to the facing channel, which is operatively connected to the inclined surface of the facing channel, and is provided with a pressing means and optionally This is achieved by having means for directing the endpaper towards the book block.

Further advantageous features are apparent from the appended claims.

In contrast to applying glue to a book block with the known generally mushroom-shaped sloped back, the present invention provides a consistently flat application surface with the region of the endpaper positioned and held and deflected from the book block. suitable for obtaining a high degree of reliable functionality and for applying precisely dosed glue in a linear and flat manner with a fitted glue application disc. .

〔Example〕

Next, the present invention will be explained in detail with reference to one illustrated embodiment.

As is known, endpaper adhesive equipment is used to position and adhere endpapers to the first and last folds of a book block.

In a first embodiment of the invention, a book block 1 is fed in an upright position in a transfer path 2 to a gripping and transporting device 3 of a perfect binding machine, as is known in the art. In that case, the book block 1 stands on a lower support surface 4 and is held by lateral guides 5. A carrier 6 of a rotating transport device behind the book block 1 performs the transport action. The endpapers 1a and 1b, which require gluing, which is also known and therefore not shown in detail, are separated from the two paper feeders 7 consisting of loading stores provided above and to the sides of the transport path 2. is fed into a U-shaped endpaper passage 8 in the guide 5 and sent forward by the carrier 6 together with the book block l, in which case the endpapers la and 1b are held parallel to the book block l by the guide plate 9. held in an upright position.

The lateral facing passages 8 are spaced apart from the transfer passage 2 and are placed against the support surface 4 of the passage 2 in order to create the backs of the facings ta and tb during the subsequent finishing of the spine of the book block. It is slightly deviated upward.

According to the invention, laterally facing facing paths 8 along the transfer path 2 extend up to the gripper conveying device 3 of the perfect binder and are gradually inclined from a starting position parallel to the transfer path 2 and the book block 3 to 45 The transition to the final position is then started after closing the clip 3a, ie after receiving the book block and both endpapers.

In the region of this final inclined position of both facing channels 8, a glue application disk 10 is provided, which extends from below into the channel 8.
It has a conical application surface 1 (Ia) extending at the same slope as the slope 8a at the top of the channel 8 so as to penetrate into the slope and act on the slope 8a in the direction of supporting the facings 1a and 1b.

The book block l and the endpapers 1a and 1b are pushed together by the carrier 6 and reach between the clips 3a;
The receiver is inserted by this clip 3a and transported in a pinched state, and in that case, the endpaper 1a in the endpaper passage 8
and the dorsal part of 1b is gradually bent outward diagonally, and in the final tilted position of 45°, the glue-applied disc i
o and glue is applied in a line. After the glue coated disc IO has passed, it is smudged.

In a second embodiment of the invention, a device for positioning and gluing the endpapers to the book blocks is provided in the transport path 18 of the perfect binder in front of the gripping and conveying device. In that case, the book block l and the endpapers la, lb are arranged in a transport path 18 with a support surface 19 and lateral guides 20.
