Description
- The present invention relates to an apparatus for feeding sets of signatures to a signature collator which has a predetermined large number of compartments.
- As is known, for book production, in general, use is initially made of folding machines, which produce, from printed sheets, corresponding signatures, a predetermined large number of which are designed to be stitched together to form a book. In particular, the signatures thus formed and stacked in sets are dropped into a collator, which has a predetermined large number of compartments, each designed to receive the said sets to form stacks of signatures. The collator subsequently supplies the signatures from all the compartments for stitching to form the desired books.
- At the present time, book production requires a high proportion of manual labour, which is used, with appropriate means of transport, to convey the sets of signatures, each set containing a multiplicity of individual identical signatures, to the collator, placing each set in the corresponding appropriate compartment.
- This mode of operation is laborious, requires the use of large numbers of personnel and is very time-consuming. Moreover, personnel may make mistakes, for example by loading the signatures into an incorrect compartment, thereby adversely affecting the quality of the books produced and even creating wastage.
- These problems have been accepted up to the present time as a matter of necessity, since no automatic line for book production, starting from the sheets to be folded into signatures and continuing up to the stitched book, has ever been made or devised.
- In the prior art are disclosed carrying elements driven in a circulating direction, charging and discharging sheet-like products, see for example documents EP 0 771 754 A and
DE 22 37 222 A. In EP 0 218 872 A it is disclosed a plurality of hoppers which are product-loadable and are transported along a path of conveyance. - It should be pointed out that this is because a hypothetical book production line would include in a single system, on the one hand, the folding machine, which is a very fast machine designed to carry out a single operation on a single part, and used for successive cycles as required, and, on the other hand, the collator, which is a relatively slow machine, but which acts on a plurality of parts, namely all the signatures required for the production of the desired book.
- The problem which has given rise to the present invention is that of devising an apparatus to feed a signature collator of the specified type, to enable such a desirable automatic line to be developed.
- This problem is solved by an apparatus of the specified type, according to claim 1.
- Advantageously, in the said apparatus there are two trains of boxes, movable independently of each other along the forward travel line.
- Also advantageously, the apparatus comprises a return travel line, forming together with the forward travel line a closed loop around which the said trains of boxes travel.
- According to a variant embodiment of the said invention, there are advantageously two trains of boxes, forming two substantially overlapping independent closed-chain box conveyors.
- Further characteristics and the advantages of the apparatus according to the present invention will be made clear by the following description of a preferred embodiment of the invention, provided for information and without restriction, with reference to the attached figures:
- Figure 1 is a schematic plan view of an automatic book production line incorporating an apparatus according to the invention;
- Figure 2 is a schematic plan view, on an enlarged scale, of a detail of the apparatus shown in Figure 1;
- Figure 3 is a schematic perspective view of a detail of the apparatus shown in Figure 1;
- Figure 4 is a schematic plan view of an automatic book production line incorporating an apparatus according to the invention, according to a variant embodiment; and
- Figure 5 is a side view, on an enlarged scale, of a detail of the apparatus shown in Figure 4.
- With reference to the attached figures, the number 1 is a general reference for an automatic book production line.
- In the line 1 there is a group consisting of a predetermined small number of folding machines, three in the example, indicated by the
numbers - The line 1 also comprises a single collator, which is indicated by the
number 5, and comprises a predetermined large number of identical compartments, fifteen in the example, all indicated by thenumber 6, each designed to house corresponding sets of signatures of the book to be produced. - It should be noted that the
compartments 6 are disposed in an alignment extending in a longitudinal direction X-X and are distributed regularly at intervals according to a predetermined step P. - The line 1 is completed by a group of stitching machines, in particular three machines, indicated by the
numbers collator 5 with identical sets of signatures, fifteen in the example, all different within each set of signatures, the signatures being disposed in the order required for the production of the book, as supplied by the collator. Clearly, in the case of books which are paperbound rather than stitched, a paper-binding apparatus would be provided in place of the stitching machines. - In line 1, according to the present invention,
corresponding stacking machines - Three
conveyor belts 13, 14 and 15, which run parallel to each other in a direction Y-Y perpendicular to the direction X-X, run from thestacking machines conveyor belts 13, 14 and 15 are disposed at intervals according to the said predetermined step P. - Each of the
conveyor belts 13, 14 and 15 runs from acorresponding stacking machine collecting conveyor belt 16, which extends parallel to the direction X-X, and therefore extends parallel to the alignment of thecompartments 6 of the collator. Thecollecting conveyor belt 16 is movable through intervals according to the said step P, over a distance which comprises afirst portion 17 in front of thebelts 13, 14 and 15, and asecond portion 18 in front of the alignment of thecompartments 6. - Between the
second portion 18 of the collecting conveyor belt and the alignment ofcompartments 6 there extends, in the direction Y-Y perpendicular to the direction X-X, a plurality of linear conveyors, all indicated by thenumber 19, one for eachcompartment 6 and each positioned level with acorresponding compartment 6. - At a
first end 20 of eachlinear conveyor 19 there is amanipulator 21, at a position between thecollecting conveyor belt 16 and the saidfirst end 20. - Similarly, at the
second end 22 of eachlinear conveyor 19, there is amanipulator 23, at a position between thesecond end 22 and thecorresponding compartment 6 of the collator. - These
manipulators - Each
linear conveyor 19 comprises two identical trains of boxes, indicated by thenumbers number 26, extending from thefirst end 20 to thesecond end 22, and along areturn travel line 27 extending in the opposite direction, the forward travel line and the return travel line forming a closedloop 28. - The two
trains train corresponding metal plates train 24, 25 acorresponding box plates - In particular, the
fixing points plates 29 of thetrain 24 are fixed to two closedchains fixing points plates 30 of theother train 25 are fixed to two closedchains - The closed
chains chains - It should be noted that the assembly consisting of the conveyor belts (13,14,15), the collecting conveyor belt, the conveyors and the manipulators (21,23) forms an apparatus 41 capable of feeding the signature collator which has a predetermined large number of compartments, with groups of sets of signatures supplied by groups of signature stacking machines.
- In operation, the folding machines are fed with sheets to be folded into signatures. In the present example, each of the folding machines carries out five cycles, folding in succession. three of the fifteen signatures required to form the desired book.
- After the folding machines, the signatures are stacked by suitable stacking machines and transferred, in sets, along the
conveyor belts 13, 14 and 15. The sets are dropped from the conveyor belts on to theportion 17 of the collectingconveyor belt 16 which is movable by steps. - The
collecting conveyor belt 16 which is movable by steps positions itself in such a way as to supply the manipulators with three sets of signatures, exactly level with the position of thecompartments 6 of the collator, for which the three sets are intended. - The three sets are dropped by the
corresponding manipulators 20 into theboxes 31 of thefirst train 24, which, being also movable by steps, halts next to thefirst end 20, alongside themanipulator 21. - With successive stepping movements of the collecting
conveyor belt 16, numbering five in total, all fifteen of the signatures required for the formation of the book are dropped into the boxes of thefirst train 24 of eachlinear conveyor 19. - When the
trains 24 are full, they move along theforward travel line 26 and are carried to thesecond end 22 of each conveyor, next to thecorresponding manipulator 23. - The
manipulators 23 start to feed the sets of signatures into thecompartments 6 of the collator. - In the meantime, the
second trains 25 travel along thereturn travel line 27 and are carried to thefirst end 20 within the range of themanipulators 21. - In other words, each of the
trains corresponding manipulator 21 when it is at thefirst end 20 of theconveyor 19, and supplies these sets to themanipulator 23 when it is at thesecond end 22 of the said conveyor. - Particularly the
boxes boxes forward travel line 26, in synchronization with thefirst manipulator 21 to receive sets of signatures supplied by the group ofsignature stacking machines forward travel line 26, in synchronization with thesecond manipulator 23, to transfer the said sets of signatures from theboxes boxes compartment 6 of thecollator 5. - The principal advantage of the apparatus according to the present invention is that it makes it possible to feed, in a fully automatic way, the signatures supplied from folding machines, which act in a very fast cycle on individual components, to a collator, which acts with an operationally slow cycle on a plurality of components.
- A further advantage of the apparatus according to the present invention is that it has been found to have a simple and reliable structure, which is not the least of the advantages for an apparatus which is required to have a substantially continuous operating cycle.
- A further advantage of the apparatus according to the present invention lies in the correctness of the completed books, preventing any possible manual error typical of the known art.
- With reference to Figures 4 and 5, the description of a variant embodiment of the invention is given below; in this embodiment, parts structurally or functionally identical to those shown in Figures 1 to 4 have the same reference numbers.
- In a
line 51 according to Figures 4 and 5 there arelinear conveyors 52, each of which comprises two trains ofboxes chain box conveyors forward travel line 26 and areturn travel line 27. - The closed-
chain box conveyor 55 has a greater length and is disposed below, while the closed-chain box conveyor 56 has a smaller length and is disposed above, substantially overlapping theconveyor 55. - Owing to its smaller length, the
upper conveyor 56 allows the signatures to be loaded into and discharged from thelower conveyor 55 byfirst manipulators 57 andsecond manipulators 23 operating at thefirst ends 58 and at thesecond ends 59, respectively, of thelinear conveyor 52 and facing thestacking machines collator 5 respectively. - It should be noted that in the
line 51 the number offirst manipulators 57 is equal to the number of the stacking machines in the group of stackingmachines first manipulators 57 being movable in the longitudinal direction X-X parallel to the alignment of thecompartments 6 of the collator. The stackingmachines corresponding folding machines linear conveyors 52 of the fifteen linear conveyors of theline 51. - Each of the three
first manipulators 57 takes signatures from a corresponding stacking machine and deposits them in the boxes of alinear conveyor 52 of the corresponding group of five linear conveyors; more precisely, it deposits them successively in one of the two trains ofboxes manipulator 23. - The
first manipulators 57 are of a conventional type. For example, themanipulator 57 may comprise a head 60, which is movable in the three orthogonal directions "a", which is longitudinal and parallel to X-X, "b", which is vertical, and "c", which is transverse and parallel to Y-Y, and is rotatable through 180° as shown by the arrow "d". The head 60 is provided with agripper 61 which can be orientated as shown by the arrow "e" to take sets of signatures from the stacking machines and to release them into the boxes of the trains ofboxes - The assembly consisting of the
linear conveyors 52 and themanipulators apparatus 62 capable of feeding the collator with sets of signatures supplied by groups of stacking machines. - The
line 51 according to the variant in Figures 4 and 5 provides the advantage of an unusual compactness, owing to a reduced length of the linear conveyors, for the same output, and is structurally simple, owing to the reduction of the number of first manipulators. - Clearly, a person skilled in the art may make numerous modifications and changes to the apparatus described above, in order to meet contingent and specific requirements, all such modifications and changes being contained within the scope of protection of the invention, as defined by the following claims.
