Definitions

  • the present invention relates to a three-sided cutting machine, used in bookbinding for trimming books on the unbound sides. This operation is performed in order to make the side edge of a book even and substantially smooth, removing any overlapping unevenness between pages.
  • This operation can be performed by a machine provided with three blades, each operating on an edge of the bound book. Anyhow, the operation of the three blades provides the binding not only of the internal pages of the book but also of the two covers, evening them up with the pages. This effect is required for many kind of books, but not for all.
  • some covers have a internally folded flap, placed at the opposite side of the binding, which edge can be aligned with the internal pages or can be projecting, for making the opening of the cover easier.
  • This arrangement can be used on both covers of the book.
  • cutting machines operating only on the two opposite sides next to the binding have been provided.
  • This arrangement is normally achieved by disassembling or deactivating one blade in three blades machine, in particular the one directed to the cutting of the side opposed to the binding.
  • the trimming on said side is performed separately, using a single-side trimming machine, paying attention to shift and/or open the covers for not cutting them.
  • the technical problem underlying the present invention is to provide a three-sided cutting machine allowing to overcome the drawbacks mentioned above with reference to the known art.
  • a three-sided cutting machine as mentioned above, characterized in that it comprises:
  • the main advantage of the machine according to the present invention lies in that it allows, in a single solution, the three-sided cutting of a book in its final binding step both in case of covers to be trimmed together with the internal pages, both in the case wherein the front cut should only involve the internal pages.
  • the lateral cutting blades and the front cutting blade are parallel to the first and second path, respectively.
  • a three-sided cutting machine is overall indicated with the reference number 1 and it is shown without its external body completely enclosing the structure of the machine 1, being provided with doors and windows required for the operation and maintenance thereof.
  • the machine 1 comprises a substantially conventional supporting frame, supporting all the operative parts of the machine 1, that will be described in the following.
  • the cutting machine 1 is directed to books B trimming, the book B comprising a pair of covers, a back providing the binding thereof, and internal pages.
  • the external edges, corresponding to the free ends of pages and covers are identified in the book B.
  • the edges will be subjected to a respective trimming or cutting, in order to make the edges of pages and covers even.
  • the covers have a respective flap folded therein which is integral to the cover itself. Accordingly, in order to preserve the covers integrity, these should not be involved in the front cut, while they should be subjected to the lateral cut.
  • first rectilinear path 2 onto which books to be trimmed are sent by a conveyor system formed by a first longitudinal chain 3 provided with suitably spaced pushing members (not shown), passing through a receiving plate 4 receiving single books to be trimmed.
  • the first longitudinal chain 3 moves intermittently, in synchronization with the introduction of books.
  • the machine 1 comprises substantially conventional means for introducing books in the machine 1, comprising a roller carpet 5 onto which the books B slides.
  • the carpet 5 position is such that the books B introduction takes place according to a direction substantially perpendicular to said first path 2.
  • the books B arrive with the front edge facing the motion direction on the first path 2, therefore the pushing members push on the back.
  • the machine On the side of the receiving plate 4 opposed to said roller carpet 5, the machine has a first stopping ledge 6, against which the books B terminates their run from carpet 5 and begin to be pushed along the first path 2.
  • the machine 1 has a first longitudinal ledge 7, next to the roller carpet 5 and therefore parallel and next to the first path 2.
  • first longitudinal ledge 7 is placed at the entry side of the first path 2, in a position opposed to the stopping ledge 6 and projecting therefrom.
  • first reciprocating pressing means are provided, moving the books to be trimmed B against said first longitudinal ledge 7 by operating on the side edge of the book B.
  • the book B initially resting against the stopping ledge 6 but without a defined position, is precisely aligned with the respective side edge sliding leaning against said first longitudinal ledge 7, for the entire length of the first path 2.
  • the machine 1 has a longitudinal belt 8, tightened between two pulleys 9, made of soft material, pressing on the book B for keeping it in a fixed translation position, while the book keeps on moving.
  • the machine 1 comprises a pair of lateral cutting blades 11, 12 parallel therebetween and parallel, in the present example, to first path 2, operating thereon and apt to provide a simultaneous trimming on the opposed side edges L of the book B to be trimmed.
  • the blades 11, 12 operates cooperating with a pair of respective vertically disposed pressing plates 13, 14, the lower edges thereof resting on the upper surface of the book B an instant before the blades 11, 12, running above said plates 13, 14, lower on the book B performing the cut.
  • Blades 11, 12 are moved according a reciprocating motion along a vertical axis by a suitable crank-connecting rod system 15, operated by an electric motor 16.
  • a brushless electric motor is preferable for the pressing plates 13, 14, as they requires a very precise motion.
  • the book B is pushed by the pushing members beyond the belt 8, up to the terminal end of the first path 2.
  • the machine 1 comprises a second path 20 perpendicular to the first path 2 and jointed thereto at the terminal end thereof, onto which the books translate without rotating, thus being subjected to 90° deflection but without changing his translation position.
  • the machine 1 On the second path 20 the machine 1 comprises a further conveyor system formed by a second longitudinal chain provided with suitably spaced pushing members (not shown), passing through a joint area 21 between the path 2 and 20.
  • the books B slide along the second path 20 with the front edge parallel thereto and facing the motion direction on the first path 2. Therefore, the pushing members of the second chain pushes on an already trimmed side edge L.
  • the machine On the side of the joint area 21 opposed to the first path 2, the machine has a second stopping ledge 26, against which books B stops their run from the joint between paths 2, 20, and begin to be pushed along the second path 20.
  • the machine 1 has a second longitudinal ledge 27, next to the terminal end of the first path 2 and therefore parallel and next to the second path 20.
  • the second longitudinal ledge 27 is placed at the entry side of the second path 20, in a position opposed to the second stopping ledge 26 and projecting therefrom.
  • second reciprocating pressing means are provided, moving the books to be trimmed B against said second longitudinal ledge 27 operating on the front edge F of the book B yet to be trimmed.
  • the book B which is initially resting against the second stopping ledge 26 but without a precise position, is precisely aligned with the respective back sliding leaning against said second longitudinal ledge 27, for the entire length of the second path 20.
  • the machine 1 comprises lifting means for lifting the covers of the book, so that the front edge F of the book to be trimmed B remains uncovered in association with its sliding motion.
  • the second conveyor belt cooperates with a sliding carpet 22 placed such that it does not interfere with a portion of the book B in correspondence of the front edges F.
  • a further belt exerting pressure on the upper surface of the book and moving according to the pushing chain of the second path 20 can be provided. Said belt is lifted in correspondence of said second reciprocating pressing means, for allowing the displacement of the book under their operation.
  • the means for lifting the covers of the book comprises an opening 23 on said second path 20, such that it provides the downfall displacement of the cover facing downwards of the book to be trimmed.
  • a longitudinal lower rod is provided, parallel to second path 20, and being interposed between the lower cover and the pages. Accordingly, it moves the lower cover away from the pages and, at the same time, provides a resting base for the front edge F sliding thereon.
  • deactivating means for deactivating the opening of said cover are also provided, formed by a removable covering (not shown) of said opening apt to deactivate such falling and to cover said lower share, that can be supported with the help of said longitudinal rod.
  • the means for lifting the book covers comprises a lifter 24 provided with one or more suction cups 25 operating on the upper exposed face of the cover facing upward, a control for potentially deactivating the operation thereof being provided as means for deactivating the lifting means of the book covers.
  • an upper longitudinal rod 28 is provided, being inserted between the upper cover and the pages and therefore moving the upper cover away from the pages.
  • the machine 1 comprises a front cutting blade 30 which, in the present example, is parallel to the development of the second path 20. It operates on one side thereof for performing a front edge F trimming of the book B to be trimmed.
  • the front cutting blade 30 operates cooperating with a respective vertically disposed pressing plate 31, the lower edge thereof being resting on the exposed upper surface of the book B pages an instant before the blade 30, running above said plate 31, lowers on the book B performing the front cut.
  • the blade 30 and the respective and pressing plates 31 are moved according to a reciprocating motion along a vertical axis by means of a suitable crank-connecting rod system 32, operated by an electric motor 33.
  • the operation of the two lower and upper shares stops and, therefore, a guide driving the lower cover back in its position is provided.
