Description

The invention relates to a device and a method for carrying out at least one cutting operation for the purpose of producing a book, a booklet or the like, in particular a book-like identification document such as a passport book.

A book includes pages tied to a spine. In addition to the pages, a book may include a book cover that includes covers. In one of the book's final steps, the book is brought to its final format by cropping the book on the non-bound pages of the book. This is necessary to be able to compensate for inaccuracies when cutting a sheet and to allow even edges of the book.

According to the state of the art, books, in particular passport books, are fixed before trimming in a device suitable for trimming, in particular by pressing the book between two restraints. As a result, the respective book is held positionally stable.

The back is formed by a form element, which connects the substantially parallel to each other arranged lid or the first and last pages of the book. Typically, such a spine has a convex shape extending between said covers. He is therefore not held by the press of the book on the lids or the first and last pages positionally true. When the book is trimmed, it can lead to deformations of the back and as a result to damage, especially in the form of slight tears on the lateral boundary of the back, especially at the point where the lateral boundary of the back in the lateral boundary edge of a connected cover or a cover page passes. These damages occur in various techniques for trimming, including cutting and milling. They reduce the visual impression of the book and should be prevented. By the lateral boundaries of the spine are meant the areas which bound the spine at its opposite sides along its longitudinal extent.

The object of the present invention is to provide an apparatus and a corresponding method for carrying out a cutting operation for the purpose of producing a book, which enable a cutting operation on a book in a simple and high-quality manner.

This object is achieved by the device for carrying out at least one cutting operation according to claim 1 and the method for carrying out at least one cutting operation according to claim 7. Advantageous embodiments of the device are specified in the subclaims 2 to 6. Advantageous embodiments of the method are specified in the subclaims 8 to 10. These and other embodiments will be described below.

A first aspect of the invention relates to an apparatus for carrying out at least one cutting operation for the purpose of producing a book comprising book pages bound to a spine. In this case, the device has a receiving element for receiving the book in a first plane, and a cutting unit for acting on the book with a cutting force substantially perpendicular to the plane. The device furthermore has at least one first support device with at least one first support element which is arranged or can be arranged to abut against at least one region of the back and thus counteracts at least one region of the back with one of the cutting force substantially when the cutting force is exerted on the book to support directed supporting force, that is, that the support element is designed to position a contact surface at an angle relative to the plane on this, which can be applied to the back of the book.

Under a receiving element is e.g. to understand a die for pressing and thus fixing recording of the book during the cutting process.

This embodiment of the device is advantageous because it allows support of the back and thus counteracts the deformation of the back and the associated damage in the form of slight tears in the region of the back.

According to a further embodiment, the device is set up such that the support element is set up and arranged or can be arranged so that it is flush or with a minimum distance of a maximum of 1 mm, in particular a maximum of 0.5 mm, with a second plane in which the cutting force applied to the book completes.

In the plane in which the cutting force is applied to the book, runs the edge, which is produced by a separation process, in particular by cutting or milling. In other words, the distance between the support element and the cutting tool or its cutting edge, when it performs the cutting process, meant.

In this embodiment, it is particularly advantageous that the areas of the back are supported, which are in the vicinity of the edges or are limited by the edges that are produced by the cutting process.

According to one embodiment of the invention, it is provided that the device has a second supporting device designed in accordance with the first supporting device, whose supporting elements are configured and arranged or arrangeable such that at least these end regions can be supported by a respective supporting element during cutting operations on the opposite end regions of the back are.

This means that at least two support elements are designed and arranged or can be arranged such that with them during cutting operations at the opposite end regions of the back, at least these end regions can be supported by a respective support element, wherein the support elements are arranged on a common support device or on separate support devices.

In this case, the end regions of the spine designate the regions of the spine which adjoin the edges which are produced by the cutting process.

In this embodiment according to the invention, it is advantageous that at the same time both end regions of the back are supported and the trimming of both supported edges is possible without the book having to be moved.

The embodiment according to the invention, in which a plurality of support elements are present, allows effective support of several areas of the back in one step. The embodiment according to the invention, in which a plurality of support elements are arranged on separate support devices, enables a time-saving arrangement of the individual support elements with respect to the back.

According to a further embodiment of the devices, the support element is set up and arranged or arrangeable such that it encloses the entire back in at least one respective end region of the back in a form-fitting manner.

The entire back here enclosed is described by the thickness of the book which defines the extent of the back between the covers and the first and last pages of the book.

In this embodiment according to the invention it is advantageous that such a uniform pressure can be exerted on the entire back and over the entire thickness of the book, a fixation of the back is effected so that over the entire width of the back tearing is prevented or reduced.

In the previously described embodiments of the device, it is possible for a support element to abut or be pressed against a part of the spine. Furthermore, it is possible that a support element or a plurality of support elements are formed such that it or they support the back over its entire length or support.

These embodiments have the advantage that a support along the entire length of the back takes place and thereby gives a particularly high stability.

According to a further embodiment, the device is designed such that the support device is pneumatically driven or drivable to apply the support element to at least a part of the back.

The pneumatic drive of this embodiment of the invention is advantageous because in pneumatically operated systems, the exhaust air can be discharged to the environment and therefore the device does not have to include return lines. This facilitates the maintenance of the device. In addition, due to the programmatic drive, the pressure force applied to the back can be adjusted very precisely or avoid overload. Furthermore, due to the pneumatics used, no contamination is to be feared.

A further embodiment provides that the device according to the invention comprises at least one rotary joint, on which the support element is rotationally mounted, in order to apply the support element to at least a part of the back.

This embodiment allows tilting of the support elements in the direction of the back. If the device comprises more than one support element, the support elements can be arranged on a common connection element that is rotatably mounted and allows common tilting of the support elements.

In this embodiment, it is advantageous that a movement of the support elements in the direction of the back is made possible with a relatively inexpensive device. The movement of the support elements in the direction of the back is made possible by a tilting, which is caused by a vertical movement of a piston.

A further aspect of the invention relates to a method for carrying out at least one cutting operation for the production of a book comprising book pages bound to a back, in which a book is fed to a device according to the invention, the book is received in or on the receiving element, the Book is fixed in or on the receiving element and the support member of the supporting device and the book are thereby positioned in relation to each other so that the support member rests against at least a portion of the back of the book. The book is acted upon by means of the cutting unit with at least one cutting force substantially perpendicular to the plane of the receiving element, wherein the support member against the effective direction of the cutting force exerts a supporting force on at least a portion of the back on the book.

In this case, a separation process, in particular the cutting or milling, exercised on at least one of the unbound pages of the book. It works one of the Supporting element exerted supporting force with at least one component perpendicular to the first plane and thus also against at least one component of the cutting force.

According to the invention, it is possible both for the support element to move in the direction of the book and for the book to be moved in the direction of the support element.

An advantage of this embodiment of the method according to the invention is that prior to the cutting process, a support member and a back are positioned to each other such that the support element abuts the back and causes a force that counteracts the cutting force and thus can counteract damage in the area of the back.

According to a further embodiment of the method, the support element is moved pneumatically and thus mechanically causes a pressure force on at least one region of the back.

In this case, the pressing force caused by the support element acts positively against the cutting force or else with a component parallel to the plane of the receiving device for the purpose of non-positive fixation of the back region.

According to one embodiment of the method, the cutting operation is realized by a translational movement of a cutting element or by a rotary movement of a milling cutter.

Damage to the back occurs both when trimming by a translationally moving cutting edge and when trimming by milling. The device according to the invention and the method according to the invention can, in particular in the case of these two common techniques of the cutting, counteract damage to the back and improve the visual impression of the book after the trimming. This allows a versatile applicability of the device according to the invention and the method according to the invention.

According to a further embodiment of the method, a three-side trimming is carried out with the cutting device.

This means that in the cutting device all three unbound pages of the book can be cropped, without having to change the positioning of the book between the individual cuts. This reduces the workload.

A further embodiment of the invention provides that it can also be used in cutting devices which do not permit trimming on three sides without rearrangement of the book.

The device according to the invention and the method according to the invention are versatile industrially applicable. You can for trimming different embodiments be used by books, brochures or the like. In particular, they can be used when trimming a book-type identification document such as a passport book.

The book 30 is positioned with the aid of a transfer device with exact position on an upper receiving element 13 below the fixed upper clamping 14 and held there. Subsequently, the movable lower clamping 16 is pneumatically moved vertically upwards. The book 30 is pressed accurately between the upper clamping 14 and the lower clamping 16. The support device 20 is pneumatically actuated such that the support elements 24 of the support device are applied to the back 34 of the book and / or press against it. If the book 30 so braced, the cutting process, in particular the milling, the unbound pages 36 of the book.

The Figures 1A and 1B show a detailed perspective view of a support device 20 for supporting a back 34 of a book during a cutting process for the production of the book 30. The support device 20 comprises two support elements 24 which are arranged individually on a common connecting element 22. The connecting element 22 is connected via a first rotary joint 19 pivotally connected to a part of a movable lower clamping 17. Via a further, second rotary joint 18, the connecting element 22 is pivotally connected to a first piston 42. The first piston 42 is arranged in a first cylinder 46 and pneumatically driven. This embodiment of the invention allows a tilting of a part of the support device 20, in particular of the connecting element 22 and consequently of the support elements 24 to the first rotary joint 19. Die Figure 1A shows an embodiment of the invention with retracted first piston 42, which means that the first piston 42 is in the retracted position in the first cylinder 46. The support elements 24 are in their starting position. The FIG. 1B shows an embodiment of the invention with extended first piston 42, which means that the first piston 42 has been moved within the first cylinder 46 upwards. As a result, the connecting element 22 is pivoted on the first rotary joint 19 and thus tilted. As a result, the support members 24 are tilted in comparison to the starting position, so that they, as will be explained below, can be applied or pressed against the back 34 of a book.

The FIGS. 2 to 7 each show a representation, partially in perspective, partially as a cutaway view of a section of a cutting device 10 which means a device for performing at least one cutting operation for the purpose of producing a book 30 is meant. The cutting device 10 comprises a housing 1 Figures 2 and 3 show the device 10 according to the invention with a book 30, which at the top Clamping 14 is positioned and with a movable lower clamping 16, which is in the starting position. The book 30 can be kept here for example due to a pneumatically generated negative pressure at the upper clamping 14. The FIGS. 4 and 5 illustrate that the movable lower chuck 16 has been raised and the book 30 is pressed. The FIGS. 6 and 7 show how the support members 24 are positioned on the back 34 of the book. For clarity is in the Figures 2 . 4 and 6 the fixed upper clamping 14 is not shown.

In the Figures 2 and 3 is the book 30 already placed on the upper clamping 14 positionally accurate and is held in this position. The movable lower clamping 16 is in its starting position, wherein the second piston 40 is in the retracted position in the second cylinder 44. The movable lower clamping 16 comprises the receiving element 12. The supporting device 20 is arranged on the movable lower clamping 16, so that it is also in the lower position. The support device 20 is in its initial position, in which the first piston 42 is in the retracted position in the first cylinder 46.

The position of the first piston 42 and the second piston 40 is shown in the partially cutaway view of the device in FIG Fig. 3 shown. In Fig. 2 is particularly well the arrangement of the first piston 42, connecting element 22 and the support elements 24 illustrated.

The FIGS. 4 and 5 show that the movable lower chuck 16 has been pneumatically moved to the book 30 and this presses. The second piston 40 is no longer in the retracted position in the second cylinder 44, but has been moved upwards. The book 30 is pressed accurately between upper clamping 14 and lower clamping 16 and thus clamped. The support device 20 has been arranged on the lower clamping 16 and moved together with the lower clamping 16. The first piston 42 has not been moved and is still in the retracted position in the first cylinder 46. The support device 20 is in its initial position. The position of the first piston 42 and the second piston 40 is particularly in Fig. 5 illustrated.

The FIGS. 6 and 7 show how starting from the position of the FIGS. 4 and 5 , the first piston 42 has been moved vertically upwards and as a result the support elements 24 of the support device 20 against the back 34 of the pressed book 30 and press against it.

The connecting element 22 is arranged such that it is connected by means of the second rotary joint 18 with the first piston 42. Furthermore, the connecting element 22 is pivotable by means of the first rotary joint 19 with the lower Clamp 16 connected. By this arrangement, the connecting element 22 is tiltable. When the first piston 42 is moved vertically upward, the part of the connecting element 22 is also moved upwards, which is connected via the second rotary joint 18 with the first piston 42. The connecting element 22 is pivoted about the first rotary joint 19. This has the consequence that the connecting element 22 is tilted, that is, moves from its original position with respect to the receiving element 12 and the book 30. As a result, the support members 24 change their position with respect to the back 34 of the book and are applied against and / or press against it. In the embodiment according to the invention, the two support elements 24 abut one end region of the back 34 and / or are pressed against these regions. The support elements 24 are configured such that they can each apply to the back 34 over its entire thickness and / or be pressed. This is especially in Fig. 7 illustrated. This embodiment of the invention should not be construed as limiting the invention to this form. The invention also includes embodiments of the support elements 24, which lie only on a part of the back 34 of the book and / or pressed against it, preferably on the side of the book 30 facing away from the introduction of a cutting force F1.

The present invention provides an economically interesting apparatus 10 as well as a corresponding method for carrying out a cutting operation for the production of a book 30, which makes possible a cutting operation which does not result in damage in the area of the back 34 of the book. In particular, but not limited to, this device 10 is designed for the production of a book-like identification document such as a passport book. When trimming a book 30, in particular in the region of the back 34, incorrect cut results may occur. Although the book 30 is fixed in position by pressing between upper clamping 14 and lower clamping 16, but the back 34 of the book reserves play, since the restraints do not support this area. In the cutting process, a force F1 is exerted on the back 34 of the book. This causes a deformation of the back 34. The trimming takes place on the deformed spine so that faulty cut results, in particular tears and / or fraying in the area of the back 34, can occur.

In the FIG. 8 an action of the invention is illustrated. A cutting force F1 acts perpendicularly from above on the book 30. The support members 24 support the back 34. They cause a counterforce F2, which acts from the support member 24 from below on the back of the book 30, the cutting force F1 counteracts. By means of the support elements 24 according to the invention the back 34 remains dimensionally stable during the cutting process and there is none faulty cut results in the area of the back 34, in particular tears and / or fraying. <B> LIST OF REFERENCES </ b> 1 casing 10 Sch nittvorrichtung 12 lower receiving element 13 upper receiving element 14 upper clamping 16 lower clamping 17 Part of the lower clamping 18 second rotation joint 19 first rotation joint 20 support device 22 connecting element 24 support element 30 book 32 cover 34 move 36 unbound page 40 second piston 42 first piston 44 second cylinder 46 first cylinder F1 cutting force F2 counterforce
