SU950549A1 - Machine for encasing books in dusk jackets - Google Patents

Abstract

In this machine, the books (1) are each fed to a jacket and then, during their joint onward longitudinal advance, the jacket flaps are folded around the book covers. The books (1) are to leave the dust jacket wrapping machine without quality defects in the book shape. In this arrangement, the shape of the book (1) which has more or less been lost during the dust jacket wrapping operation, is to be restored. A book shaping station with shaping elements (4, 9) is arranged adjacent to a book conveying device which is known per se, and one of the shaping elements (4) is preferably designed as a universally applicable fixed prismatic plate with a V-shaped receiving surface (5).

Description

(54) MACHINE FOR COVERING BOOKS WITH SUPERBLOCK

The invention relates to the Madonna to cover the books with a dust jacket, in which the book is transported to one dust jacket and then during further joint longitudinal feeding of the dust jacket valves are folded over the sides.

To cover books, there are some super-known machines according to DT-PS 1 103 294 which use an endless chain link as a transport device for books, some of which have recesses in the shape of trays in the direction of the longitudinal axis to receive books that are installed downwards. These recesses are primarily intended for orientation along the axis of the dust covers, regardless of thickness. During the longitudinal feed process on this link chain, the sides are opened, the flap of the dust jacket is folded and the books are closed again. Then the book again enters, are at the receiving station.

However, during transportation of the supply and in the process of opening and closing, the roundness of the book roots is broken, the shape of which is still not sufficiently stabilized, which leads to

defects. This is especially the case if the dust cover machine directly covers the production line for the production of books, since the glue in the book backs is not yet fully grasped, and therefore the shape stability is negligible.

The machines described in DT-OS 2 065 731 and OL-PS 23 920 have the same drawback. In these machines, the books are turned over in the transport process when they are covered with dust;

15 which leads to deformations of the book roots due to loads that constantly act on the roots.

In addition, books are known for covering books with a dust jacket, in which the supports on the front edges of the book binding are carried out in the rt-length direction, through a book divider, and then are taken as a supporting sheet and transported together with

25 dust jacket. The sides of books that hang on the base sheet during the longitudinal feed are opened and the flaps of the dust cover on the edges of the binding are opened. Then

The 30 books are removed from the support sheet and guided to the receiving station, resting on the front edges of the binding. However, with such a process, the roundness of KopeujKOB books is strongly disturbed, especially when transported on the front edges of the binding under the influence of the entire weight of the book block. The purpose of the invention is that the books leave the machine to cover the books with a dust jacket without degrading the quality of their form. The object of the invention is to restore the roundness of the roots, which is more or less lost during transport and covering with the dust jacket, in a dust jacket for books. The problem is solved by the fact that a molding station is located at the end of the well-known book conveyor; with the corresponding form elements, and 4TQ one of the molding elements is preferably made in the form of a universally applicable fixed prismatic plate with a V-o different receiving surface. Due to the direct effect of mechanized matching with the thickness of the molding tools book, the books are given a final high-quality form. Figure 1 shows the location of the forming station in the car for covering books with dust jacket; on figv - stan qi molding, a perspective view. The separate stages of covering with a superblock (Fig. 1) in which the book 1 is transported, installed on the roots on the plate chain, are completed in detail by the P molding station shown in Fig. 2, followed by the iTl receiving station. The P forming station (Fig. 2) consists of a laterally equipped “jumper 2 lamellar chain 3” of the lower molding element 4, which is made in the form of a prismatic plate with a V-shaped receiving surface 5. the lamellar chain 3 and the lower molding element 4 are installed the lateral continuously rotating feed rollers 6 for moving the book 1 to the lower molding element 4. On the latter there is a book 1 installed on the spine, provided with a dust jacket that is supported by the side guides 1 "from tires 1. Above the front edge of the book 1 is the upper molding element 9, interchangeable in accordance with the thickness of the book, spring 8 and moved vertically. To eject book 1 it is continuously moving with a system consisting of a chain leash 10 and chain units 11. Relocatable a plate chain 3, installed on the spine and snab enna with a dust jacket, the book 1 first falls between two side feed rollers 6, the circumference of which speed slightly exceeds the speed of transport of the plate chain 3. Rotation Tel'nykh motion communicates oschims leaning to the sides according to the thickness of the book feed rollers 6 undepicted universal joints. Thus, book 1 from the field of the wrapping jumpers 2 of the plate chain 3 enters the prismatic lower molding element 4 supporting the book back, the V-shaped receiving surface 5 of which preferably has an opening angle of 120, at which, irrespective of the thickness of the book Hmj of the book, its back is supported in npaBOfi and the left outer portion, the middle portion sags for molding. Thus, it becomes unnecessary to replace the lower molding element 5, which is associated with a different book format. During the pause in transport, | which is provided by adjusting the speed and selecting the phase of the jumpers 2, the chain leads 10 of the ejection system, the upper molding element 9, under the action of the pre-compressed springs 8, presses against the front edge of the book 1 and thus restores the roundness of the core, lost in the process of covering the super-blind: transportation. The interchangeable upper molding element 9 is selected in accordance with the thickness of the book. Its movement to the rise is created by a non-illustrated drive mechanism. After the end of its movement to the rise, at which the roundness of the spine of Book 1 is restored, the chain leash 10 moves the finished book 1 to the iTl receiving station. The guide bus lines 7, which prevent the book block from diverging under the action of the pressure of the upper molding element 8, are set to the thickness of the book by an un-displayed p; central device. In order to place the molding station C. in the car for closing books with a peroblock according to the invention, it is not essential whether the book is placed on the spine, as in the described example or the front trim is down. In this case, the lower {Shaping Molding Element 4 and the upper Molding Element 8 are interchanged and the latter is positioned under the edge of the book.
