Definitions
- the invention relates to a method and an apparatus for applying a protecting film to books or booklets.
- Object of the invention is to describe a method and an apparatus for applying a protecting film to books or booklets in order that a film is applied perfectly, but at the same time in order that the speed of application is increased considerably.
- the apparatus may apply film to books or booklets of varying thickness, making any changes in the appara ⁇ tus as well as adjustments for the thickness and other dimensions of the book unnecessary.
- a film may also be applied to books or booklets, having a highly sensitive cover.
- a film is to be applied to e.g. hardbacks, where the cover is not scratchproof, it is not sufficient merely to convey and position the books on an ordinary conveyor belt, as small sand or other dirt particles may cause scratches in the cover.
- an air cushion according to the invention scratches and other damages to the cover caused prior to the application of a protecting film, are completely avoided.
- the apparatus for applying protecting films is primarily designed as related to in the characteri ⁇ zing part of claim 8.
- the apparatus may thus in a simple manner be adjusted for books or booklets of varying thickness.
- the apparatus is primarily designed in order that adjustment of height takes place according to the thickness of the next book.
- the drawing 4 is a table or a similar machine frame carrying the whole of the film applying appara ⁇ tus.
- a case with books 1 is shown, which case is designed in order that it may hold books of varying sizes.
- the case is of a generally known sort and thus need be described in no further detail.
- the books are delivered one by one by a generally known delive ⁇ ry device to an endless conveyor belt 3, always moving in the direction indicated by arrows.
- the books are placed with their backs facing to the right and are delivered to the belt 3 in the same position. It is therefore necessary that the books 1 are always placed in the case with their back in a certain direction, but it is irrelevant whether the book has its front up or down.
- the conveyor belt 3 is supplied with a number of holes or nozzles 14 for compressed air in order to create an air cushion between the book 5 and the belt 3.
- the book 5 may be moved or pushed to its correct place along the belt, without dirt, sand or unevennesses on the belt scratching the book cover.
- a micro switch or another type of sensing device 6 acts, as soon as a book 5 passes, thus actuating an air cylinder 26 controlling a lateral steering control placing the book 5 correctly on the belt; the length of the back of the book is measured simultaneously.
- Another micro switch or another type of sensing device 9 is used for controlling the driving motor of the conveyor belt 3 in order that the books 5 and 5' are conveyed at a suitable pace and keeping a suitable distance.
- the sensing devices 6 and 9 are moreover applied for measuring the width of the book.
- the width of the book ma also be established by measuring the book case delivering the book to the belt 3.
- the film device When a book 5' 1 has reached the actual application position, the film device has been prepared. From a store roll a length of film 12 with cover film is led to a main roll 20 with a unilateral direction of rotation as shown. The length of film 12 immedi ⁇ ately meets a pulling roll 15 pulling the length of film 12 forward and delivering the cover film 11 to a store roll. Arrows indicate the direction of motion of both the length of film 12 and the cover film 11. The protecting film is led further along by a roll 16, which moreover cuts the edge of the film to the correct width in accordance with the earlier mentioned measuring of the height of the book.
- a leading roll 17 By a leading roll 17 the film is led through an opening (not shown) in the table 4 down toward a drawing and holding roll 21.
- a cutting tool 18 is operated in such a manner that a piece of film 22 of suffici- ent size for the book 5 11 is cut off, which book has now reached the film application device.
- the prepared and clean cut piece of film 22 is now held and stretched between the rolls 20 and 21 both standing still, the holding roll 19 pressing the film toward the roll 20, and the film being sucked onto the roll 21.
- the film is now ready for application, in that the adhesive side turns toward the back of the book 5' ' now to be applied with film.
- the book 5' 1 is led toward the film by the conveyor belt 3 and between the rolls 20 and 21, of which the latter is now driven in the opposite direction of rotation, whereby the piece of film 22 is rolled onto the book 5' 1 from its back toward the edges.
- Another conveyor belt 8 now takes over and conveys the book 5' ' ' to a position 5' ' ' ' , where the book is delivered for further treatment, such as manual folding of excess film along the edges of the book opposite the back.
- the main roll 20 with the auxiliary rolls 15, 16, 17, and 19 as well as the cutting tool 18 are mounted on a holder 10, which may be turned around its centre of suspension 25, whereby the position of all the mentioned parts may be changed jointly, as indicated by the double arrow next to the holder 10.
- the distance between the main roll 20 and the holding roll 21 is thus controlled by raising and lowering the holder 10.
- the holder 10 is raised and lowered by means of an air cylinder 13 with a piston catching the holder 10 by means of an arm.
- the distance between the rolls 20 and 21 is adjusted according to the thickness of the book in order that the rolls always roll the piece of film 21 onto the book 5' ' exerting a certain press ⁇ ure, irrespective of the thickness of the book.
- the roll distance is thus automatically adjusted to correspond with the size of the next book to be applied with film exactly.
- a micro switch 23 or a similar sensing device sensing the O-position to prevent the rolls 20 and 21 from pressing too hard against each other, when the apparatus does not apply film to a book.
- the driving motors for the conveyor belts may moreover be placed here.
- the individual rolls and auxiliary rolls may be driven by small electric motors or by compressed-air motors.
- the rolls 15, 16, 17, and 19, and possibly also the rolls 20 and 21 as well as the cutting tool 18 are constructed in such a manner that the highly adhesive film does not adhere, as they may be provi- ded with Teflon or a similar rejecting coating.
- the rolls 20 and 21 are primarily rubber rolls.
- the control case 24 controls the various operations of the apparatus in a generally known manner by sensing the position and size of the books, the controlling and adjusting taking place in a generally known manner by means of electric components or compressed-air components.
