Definitions

  • the invention relates to a method for manufacturing books.
  • the invention relates to a method and apparatus for manufacturing books.
  • the invention provides a method for manufacturing books including the steps of :-
  • the support platform includes guide bars, the guide bars engaging a secondary guide means as the support platform is lifted to guide the stack into the aligned position.
  • the support platform is lifted upwardly by a drive means which drives a drive train comprising a separate drive chain connected to each lifting point, and the method includes the step of driving the drive means and hence each drive chain in synchronisation with the operation of the folding unit.
  • each drive chain is trained over sprockets driven by the drive means, an end of the drive chain being connected to an associated lifting point and the other end of the chain being preferably counterweighted and free to rise and fall as the support platform is raised and lowered.
  • the method includes the steps of detecting the end of the stack, and in response stopping the drive means and the folding unit.
  • the method includes the step, after completion of the stack, of returning the support platform to a lowered pallet receiving position.
  • the method includes the steps of :-
  • the method includes the step of wrapping the stack with a plastics film after printing and stacking to retain a substantially constant humidity of the paper sheets prior to delivery to the support platform for the folding unit.
  • the books are bound by applying a hot melt adhesive and the method includes the step of curing the adhesive prior to packing the books.
  • the books are cured by leading them along a circuitous conveyor prior to packaging.
  • the method includes the steps, after binding, of :- trimming the book; weighing each book; comparing the book weight with a check weight; and rejecting any books not conforming to the check weight.
  • the method includes the steps of :- collecting waste paper generated in the book manufacturing process; shredding the waste paper; compacting the shredded waste paper; and recycling the compacted waste paper.
  • the invention also provides an apparatus for use in the method of the invention, the apparatus comprising :-
  • the support platform includes guide bars for engagement with secondary guide means as the support platform is lifted.
  • the secondary guide means preferably comprises a pair of side guide arms including a lower inturned portion in which the guide bars run.
  • each drive chain is trained over sprockets driven by the drive means, an end of the drive chain being connected to an associated lifting point and the other end of the chain being free to rise and fall as the support platform is raised and lowered.
  • the free end of each drive chain is counterweighted.
  • chain engagement means are provided over at least some of the sprockets to ensure engagement of the chain with the sprockets.
  • the apparatus includes switch means for disabling the drive means when the support platform is raised and/or lowered beyond preset positions.
  • the invention also provides books whenever manufactured using the method of the invention and/or utilising the apparatus of the invention.
  • a method for manufacturing books large sheets of paper are first printed using conventional printing techniques.
  • the printed sheets are then stacked on a pallet 2 which holds a stack 3 of typically several hundred printed sheets.
  • the stack of sheets 3 is preferably wrapped with a plastics film pending the further steps in the method of the invention.
  • each book is individually weighed, after trimming, and the weight is compared with a check weight to ensure that the book has the correct number of pages.
  • waste paper is generated at several stages, for example, during trimming.
  • the waste is collected, shredded, compacted and recycled.
  • the apparatus 5 comprises a support platform 10 for receiving a pallet 2 of a stack 3 of printed sheets.
  • the support platform 10 has four lifting points provided by lifting lugs 11 which are located in use adjacent the corners of a pallet 2 as will be particularly apparent from Fig. 2.
  • the apparatus 5 also includes lifting means for pulling the lifting lugs 11 upwardly in synchronisation with the operation of the folding unit 6.
  • the lifting means comprises drive means provided by a drive shaft 15 for driving a drive train extending between the drive shaft 15 and the lifting lugs 11.
  • the drive train comprises a separate drive chain 16 connected to each lifting point 11, the drive chains 16 being operated substantially simultaneously by the drive shaft 15 for controlled and accurate lifting of the support platform 10 and hence presenting a sheet from the top of the stack 3 to the folding unit 6.
  • Each of the drive chains 16 is trained over a number of sprockets 18 which are driven by the drive shaft 15.
  • An end 20 of each drive chain 16 is mounted to an associated lifting lug 11 and the other end 21 of the chain 16 is a free end which is provided with a counterweight 22 to retain the chain 16 in position and ensure that the chain remains in contact with the sprockets 18.
  • a segment-shaped chain engagement 25 means is positioned over at least the main driven sprockets, to ensure that the chain 16 is retained in positive contact with the sprockets of the sprocket wheel.
  • the drive is optimised to ensure that all the lifting points 11 and hence the support platform and top row sheet 2 in the stack 3 is presented to the folding unit in such a way that the folding unit is synchronised with the presentation of the sheets so that the folding unit operates at optimum operating conditions.
  • a control unit 31 having a sheet engaging extension arm 32 monitors the delivery of sheets to the folding unit from the stack and ensures that the drive shaft 15 is driven in synchronisation with the operation of the folding unit.
  • the apparatus 5 also includes a guide means for guiding the stack into an aligned position on the support platform 10 for delivery of single sheets from the top of the stack 3 to the folding unit 6.
  • the guide means is provided by guide strips 40 against which the stack 3 is engaged.
  • the guide means also includes secondary guide means provided by a pair of side angle-shaped guide arms 45 which include a lower inturned portion 46 as illustrated particularly in Figs. 9(a) and 9(b).
  • the platform 10 includes projecting bars 50 which run in the guide arms 45. The arrangement is such that when a pallet 2 with a stack 3 is loaded by means of a forklift truck onto the platform 10, the stack 3 is not pushed against the guide bars 40. On lifting of the platform 10, the bars ride up along the lower portion 46 of the guides 45 which causes the stack 3 to move inwardly against the guides 40. In this way, the stack 3 is presented to the folding unit in a consistent and optimum manner at all times.
  • switch means is provided by upper and lower limit switches 59,60 which are operated by a switch arm 63 carried by the platform 10.
  • the switches 59,60 cause the drive means to be disabled when the platform 10 is raised and/or lowered beyond preset positions.
  • the method and apparatus of the invention particularly allows a folding unit to be loaded with stacks of printed sheets for folding in a highly efficient and optimum manner for folding. Minimum handling is required and a high level of efficiency and quality is achieved with the folding unit as the sheets are always presented to the folding unit in a consistent manner. Manufacturing efficiency is thereby optimised.
