Definitions

  • the present invention finds application in the field of bookbinding equipment and particularly relates to a fluid or semifluid adhesive delivering head for binding machines designed for binding sheet elements in blocks, such as blocks of paper sheets for books, agendas, albums or the like.
  • the invention further relates to a binding machine incorporating such adhesive delivering head.
  • the sheet elements may be sheets of printed or blank paper of various sizes, which are bound with a more rigid cover to form books, catalogs, notebooks or the like.
  • one of the most widely used techniques to form the binding consists in joining the cover to the block by applying a preset amount of adhesive along its back.
  • the step of applying adhesive to the block is carried out by adhesive delivering heads incorporated in machines that implement the whole bookbinding process.
  • a back with adhesive-free or poorly adhesive areas may cause failed local adhesion of the cover to the sheet elements, and consequent removal of the latter from the cover, thereby affecting the binding.
  • applicator devices In an attempt to improve adhesive distribution on the back of a block, applicator devices have been developed, which are designed for calibrated, uniform delivery of a predetermined amount of adhesive.
  • US 4,512,945 discloses an adhesive delivering head having an adhesive collecting chamber connected to an external tank through a feed pump.
  • the collecting chamber is held in a supporting frame having a seat designed for passage of the block, with a delivery slot formed therein having a plurality of outlet holes.
  • the collecting chamber is put in communication with the holes through a passage whereat two opposite movable piston-like pressure members are located, which have sealing elements for conveying the adhesive to the outlet holes, while controlling the delivered amount.
  • a first drawback of this solution is that the delivery of adhesive through the holes is affected by any water hammer occurring due the motion of the pressure means.
  • the stick slip motion of the pressure members causes discontinuous feeding through the holes and hence uneven delivery of adhesive to the back of the book.
  • a further drawback is that the total amount of delivered adhesive only corresponds to the desired amount if the movement of the pressure members is synchronized. This will require the provision of expensive devices for controlling the movement of the pressure means.
  • a further drawback is that the collecting chamber contains a considerable amount of adhesive, and that cleaning of the device requires discharge of such amount of adhesive and use of relatively large amount of cleaning liquid.
  • the amount of excess adhesive delivered through the slot may contact other external parts of the device, and cause fouling thereof.
  • US 5,129,772 discloses a further adhesive delivering head for binding machines in which the head, in a first configuration, comprises a seat for passage of the back of the block to be bound, in which seat a slot is formed to define an outlet for the adhesive.
  • This configuration does not allow uniform distribution of the delivered adhesive all along the slot, and will result in less than optimal block binding.
  • the same document also discloses a second configuration, in which adhesive is directly fed into the seat for block passage without flowing through an extrusion slot, and is distributed by a plurality of nozzles accommodated in the seat, for a plurality of adhesive beads to be applied along the edge and the side faces of the block.
  • the adhesive is distributed on the back in a discontinuous manner and the quality of binding is not adequate for all applications.
  • the object of the present invention is to overcome the above drawbacks, by providing an adhesive delivering head for binding machines that is highly efficient and relatively cost-effective.
  • a particular object is to provide an adhesive delivering head that affords even and accurate distribution of a predetermined amount of adhesive on the back of a block, while ensuring constant delivery.
  • a particular object is to provide an adhesive delivering head that affords highly accurate metering of the delivered adhesive, while reducing waste and simplifying cleaning operations, particularly allowing the use of a smaller amount of cleaning fluid.
  • a particular object is to provide an adhesive delivering head that allows removal of excess adhesive from the back of the block without fouling parts other than the adhesive delivery area.
  • a particular object is to provide an adhesive delivering head that has a smaller number of parts subjected to wear, which are easily replaceable.
  • Another important object of the invention is to provide a binding machine for binding blocks that uses such adhesive delivering head.
  • an adhesive delivering head for binding machines as defined in claim 1.
  • the adhesive may be spread in a substantially uniform manner all along the slot, while avoiding pressure bursts.
  • the invention relates to a binding machine for binding sheet elements as defined in claim 9, which uses such adhesive delivering head.
  • the adhesive delivering head may be used to spread a predetermined amount of liquid or semiliquid adhesive on the back D of a plurality of sheet elements F gathered in side-by-side relation into a block B having a thickness s.
  • the sheet elements F may consist of paper sheets, either printed or blank, to form a book, a catalogue or the like.
  • the head 1 may be used to spread the adhesive on blocks B of various thicknesses s and various lengths.
  • the head 1 may spread heat melting adhesives of various types, such as polyurethane, hot melts and EVA adhesives, and allows delivery of adhesives with different melting points.
  • the head 1 may be incorporated in any binding machine, not shown as a whole and known per se, or may form a self-supporting station designed to be associated with one or more additional workstations of an existing machine.
  • the binding machine may have one or more adhesive delivering heads 1 of the invention and may include an external storage tank R and pump means P for pumping and conveying the adhesive towards the head 1, as schematically shown in Fig. 3 .
  • an adhesive delivering head 1 essentially comprises a main frame 2 having a longitudinal seat 3 for guiding the back D of the block B of sheet elements F to be bound.
  • the seat 3 may be delimited by a pair of slides 4, 4' located on the upper surface 5 of the frame 2.
  • the slides 4, 44' may be movably mounted to the frame 2 to slide thereon in a direction substantially transverse T to the seat 3 to change the width w thereof.
  • such slides 4, 4' may be fixedly connected to the frame 2 to define a seat 3 having a predetermined, constant width w.
  • the slides 4, 4' may be moved towards and away from each other using drive means 6 associated with the frame 2 and connected to the slides 4, 4' by transmissions 7 or other mechanisms.
  • the width w of the seat 3 may be relatively greater than the thickness s of the block B to allow passage thereof through the seat 3.
  • the head 1 comprises a substantially transverse slot 8 formed in a portion 9 of the seat 3 for local distribution of a fluid or semifluid adhesive on the back D to be bound.
  • the slot 8 may be disposed in the frame 2 in a substantially central position.
  • the seat 3 may be designed to hold the back D close to the slot 8, lying on the upper surface 10 of the seat 3 or slightly raised therefrom.
  • the distance d between the slot 8 and the back D may be of a few tenths of a millimeter, but it may be changed by adjusting the position of the back D, i.e. by lifting the back D of the block B, e.g. using appropriate gripper means, not shown.
  • the head 1 may be associated with translation means for causing vertical translation of the frame 2 or a part thereof associated with the seat 3, which means are not shown and may be of hydraulic, pneumatic or electromechanical type.
  • the length g of the slot 8 may be substantially equal to the width w of the seat 3, if the latter has a fixed, predetermined value.
  • the slot 8 will have a maximum length g slightly smaller than the maximum width w of the seat 3.
  • any change of the width w of the seat 3 may result in a change of the length of the useful portion 11 of the slot 8.
  • Each slide 4, 4' may have a respective substantially vertical channel, one of them being only visible in Fig. 1 and referenced 8', which are located at the slot 8 in fluid connection therewith.
  • the adhesive may also flow out of the channels 8' to be spread on an edge portion of the side faces of the block B.
  • the amount of adhesive that can be delivered by the slot 8 may be controlled according to the thickness s of the block B to be bound and the speed at which the block B moves on the slot 8.
  • the flow rate through the slot 8 shall be simply increased as the speed of the block B increases.
  • controlled feeding means 12 are provided for feeding a predetermined amount of adhesive into the slot 8, which means are located below the slot 8 and upstream therefrom to cause adhesive to flow if it by a flow action from the underlying area.
  • the controlled feeding means 12 comprise a plurality of feeding elements 13, 13', 13", 13"' in fluid communication with the slot 8 and evenly distributed in a substantially transverse direction parallel to the extension of the slot 8 for spreading the adhesive in said distribution portion 9 in a substantially uniform manner.
  • feeding elements 13 may be provided, depending on the size of the head 1. In the configuration as shown in the drawings by way of example and without limitation, the head 1 has four feeding elements 13.
  • the feeding elements 13 are evenly arranged along the width of the slot 8.
  • the distance between two adjacent feeding elements 13 may be selected to ensure the outflow of the same amount of adhesive all along the extension of the slot 8.
  • the amount of adhesive to be spread by the feeding elements 13 may be unchanged through the various feeding elements 13 or differ from one to the other, for variable adhesive distribution in particular cases.
  • the feeding elements 13, 13' may be equally spaced, each feeding the same amount of adhesive.
  • the feeding elements 13 comprise a nozzle 14 which is adapted to be fluidically connected to a tank R for the adhesive and has an inlet section 15 and an outlet section 16.
  • the nozzle 14, as shown in Fig. 7 may be located below the slot 8 and have a substantially cylindrical shape, with the inlet section 15 substantially equal to the outlet section 16.
  • nozzles 14 may use nozzles 14 with inlet sections 15 different from the outlet sections.
  • heads 1 may be provided which deliver the adhesive within a range of transverse widths of backs D and/or within a range of moving speeds thereof, using nozzles 14 with different inlet 15 and outlet 16 sections.
  • the feeding means 12 may be associated to sensor means, not shown, which are located in the seat 3, close to the slot 8, and are adapted to detect the block B and its position relative to the slot 8 to turn the feeding means 12 on or off.
  • the sensor means may be of any type, such as photocells or other proximity sensors.
  • the controlled feeding means 12 comprise flow adjusting means 17 for adjusting the flow of adhesive to be delivered from each of the outlet sections 16 of the nozzles 14.
  • the adjusting means 17 interact with each of the nozzles 14 to adjust the amount of adhesive delivered through the slot 8.
  • these adjusting means 17 may be of either mechanical or hydraulic type and may act upon the outlet sections 16 of the nozzles 14 by the action of electronic control means, not shown.

  • the stem 22 may have a second end 24 outside the stabilization chamber 18, and associated with actuator means 25 for adjusting the distance of the first end 23 of the stem 22 from the inlet section 15 of each nozzle 14.
  • These actuator means 25 may impart a mainly translational movement to the stems 22, in a direction substantially parallel to the longitudinal direction L.
  • the stems 22 are designed to move in respective parallel directions.
