Definitions

  • the present patent concerns bookbinding, book and brochure leaf collators, and bookbinding machines in particular.
  • this patent refers to the devices and mechanisms for spreading glue on the spine of the sheaf of leaves to bind, or on any other material.
  • Each sheaf of leaves forming a book or brochure to bind is manually or mechanically positioned between the clamps, which carry said sheaf throughout the bookbinding process.
  • the sheaf carried by the clamps is earned to the vibrating table, which brings the leaves into line.
  • Rollers and blades then spread hot-melt glue on the spine of the book and possibly also on the edge of the first and last leaves on the side of the spine.
  • the cover feeder places each unfolded or ready-folded cover in the cover press, which attaches the covers to the sheaf of leaves.
  • rollers and blades for spreading the hot-melt glue are partially immersed in one or more heated tank(s) containing said glue.
  • Hot-melt in bookbinding jargon i.e. a known type of glue that is solid at room temperature but liquefies when heated to a variable temperature, depending on the different types of glue, making it fluid enough for it to be applied with the rollers and blades.
  • the glue has to be heated up to high temperatures in order for it to be used. All parts in contact with the glue melting tanks, or in the vicinity of any objects coming into contact with the glue, are consequently likely to reach high temperatures, meaning that the operator risks being burned.
  • the hot-melt glue may drip or splash outside the tanks or off the rollers or blades for various reasons. These splashes of glue soil the various pails of the bookbinding machine and can spoil the sheaf of leaves being bound, as well as posing a hazard for the operator.
  • the heated hot-melt glue becomes fluid, it retains a degree of viscosity that prevents any increase in the speed of the various parts involved in carrying and applying the glue beyond certain limits.
  • the entire bookbinding chain also has to adapt to the speed limit imposed by the type of hot-melt glue used in the gluing stage, thus limiting the speed and productivity of the whole system.
  • the glue is used up during the binding of the books, so the level in the tanks from where it is collected by the rollers and blades progressively drops, making it necessary for a feeder device or an operator to top up the tanks with more liquid or solid glue to keep the level of glue in the tanks at an optimal, or at least minimum, level for collection.
  • the amount of glue deposited on the spine of the book also depends on how much glue is collected by the rollers and blades from the corresponding tanlcs. As a consequence, when the tanks contain plenty of glue, a greater quantity of glue is deposited on the spine of the book; conversely, if the level of the glue in the tanlcs is low, a smaller amount of glue is collected by the rollers and blades and not enough glue is deposited on the spine of the book.
  • the hot-melt glue When heated, the hot-melt glue produces fumes and vapours that can have an irritating effect.
  • the patent GB 447 219 regards a glue applicator for bookbinding machines comprising a tank of glue and a vertical glue delivery cylinder, equipped with shutter. Said delivery cylinder and said shutter are equipped with openings through which the glue is extruded, and where said delivery cylinder is mobile with respect to the shutter to partially or totally close said openings to control the flow of glue.
  • One object of the new glue applicator for bookbinding machines is to use a lower working temperature for the various parts involved in distributing the glue and for the hot-melt glue.
  • Another object of the new glue applicator for bookbinding machines is to be able to use other glues, as well as the normal hot-melt glue, such as polyurethane based glues in the bookbinding process.
  • Another object of the new glue applicator for bookbinding machines is to require fewer maintenance or servicing operations by the operators.
  • Another object of the new glue applicator for bookbinding machine is to enable the application of an even, constant quantity of glue for all the paperback volumes being bound.
  • Another object of the new glue applicator for bookbinding machines is to enable the use and application of different types of glue during the course of the same bookbinding process.
  • Another object of the new glue applicator is to accelerate and facilitate the cleaning operations of the machine, particularly from the glue residues, without having to disassemble the components of the machine, such as the glue tank and/or glue delivery cylinders.
  • the new glue applicator for bookbinding machines comprising one or more tank(s) of glue with a base or body for connecting it to the bookbinding machine, one or more delivery cylinder(s) with glue delivery on/off mechanisms, one or more pair(s) of guides for the volumes to bind, and two or more components for applying the glue.
  • the tank consists of a cylindrical or otherwise shaped heated container (also called a melter), complete with a sealed cover and a device for increasing the pressure therein. It can be foreseen that said tank comprises at least one pressurised air inlet tube to cause the expulsion of the glue.
  • the base for the tank serves the memepose of supporting the tank and connecting it the bookbinding machine, and also of conveying the glue from the tank to the delivery cylinders.
  • the delivery cylinders consist of substantially parallel cylinders, lying substantially horizontally and substantially at right angles to the direction in which the volumes to bind are fed forward.
  • each of said delivery cylinders there is an on/off mechanism or valve for controlling the flow of glue from the tank and through the base to the glue applicator members.
  • Each pair of guides is installed on each of said delivery cylinders so that the two guides are parallel and the sheaf of leaves to glue passes between said two guides.
  • One of said guides is substantially fixed to the delivery cylinder, while the other can be displaced in a direction perpendicular to the movement of the volumes so as to adjust the distance between the two guides to suit the thickness of the volumes.
  • Precision displacement means are used to control the displacement of the mobile guide.
  • the components for applying the glue consist of accessories, devices, nozzles and other such elements suitable for enabling an established quantity of glue to be delivered from the delivery cylinders and spread over the spine of the volumes and along the sides in the vicinity of the spine.
  • Said components for applying the glue are installed inside the delivery cylinders and the volume guides.
  • a first type of glue applicator component consists of a slot in the top of the delivery cylinders, aligned with the axis of said delivery cylinders.
  • a second type of glue applicator component consists of a series of holes (nozzles) on the vertical side of each guide facing towards the opposite guide on the same delivery cylinder. Holes and/or channels inside the guides and in communication with the inside of the delivery cylinders enable the passage of the glue from inside said delivery cylinders through said holes in the guides.
  • the on/off mechanism or valve for controlling the flow of glue to the delivery cylinders can consist of a revolving tube, hereinafter called a shutter, housed inside the delivery cylinder and complete with slots or holes in its perimeter.
  • a shutter housed inside the delivery cylinder and complete with slots or holes in its perimeter.
  • the turning of said shutters brings the holes or slots into or out of alignment with the holes or slot in the delivery cylinders, thereby enabling or preventing the passage of the glue under pressure in the delivery cylinders through said holes or slots.
  • Said inside shutters can be turned by electromechanical or pneumatic actuators suitably controlled so as to allow the delivery of glue through the slots in the delivery cylinders, or through the slots in the guides, only when it is required, i.e. during the passage of a volume.
  • a mechanism induces a partial backflow of the glue through the delivery channels and holes when the shutter is closed to prevent any glue from leaking or overflowing through the applicator slots and holes when there is no volume on which to apply the glue.
  • the new applicator unit comprises at least one further tank for detergent fluid and/or water, connected to said glue delivery cylinders, said tank, preferably under pressure, being connected to a pressurised air inlet tube for the expulsion of the liquid glue.
  • said detergent fluid and/or water tanlc comprises at least one non-return valve, suitable to prevent the glue, circulating in said delivery cylinders during the normal operation of the machine, from going back into said tank of detergent fluid and/or water.
  • said glue tank also comprises at least one non-return valve which allows the expulsion of the glue in said delivery cylinders, during the normal operation of the machine, and prevents the detergent fluid and/or the water, circulating inside of said delivery cylinders during the cleaning cycle, from going back into the glue tank.
  • Figures 1 and 2 respectively illustrate a top view and an axonometric view of an embodiment of the new glue applicator for bookbinding machines.
  • the new applicator comprises a tank (1) with a base or body for its connection to the bookbinding machine (2), two delivery cylinders (3a, 3b) with corresponding glue delivery on/off mechanisms (4a, 4b), and two pairs of volume guides (5a, 5b).
  • the tank (1) consists of a cylinder with a sealed top cover (1.1).
  • Said tank (1) can be heated to enable the use of glues whose fluidity is improved by an increase in temperature.
  • a device or mechanism increases the pressure inside the tanlc, e.g. by delivering compressed air.
  • the base (2) for the tank (1) serves both as support for the underside of the tanlc (1) and as a means for connecting the assembly to the bookbinding machine and for conveying the glue contained inside the tanlc (1) towards the delivery cylinders (3a, 3b).
  • Said delivery cylinders (3a, 3b) consist of cylinders lying substantially parallel to one another, substantially horizontal and substantially at right angles to the direction in winch the volumes to bind are fed forward.
  • the delivery cylinder (3 a) that the volume encounters first has a slot (3ac) to the top, lying parallel to the length of the delivery cylinder (3a).
  • the glue applied to the spine of the volume is delivered through said slot (3ac).
  • the delivery cylinder (3 b) that the volume encounters afterwards has two holes or openings (3bc) in its upper part, coinciding with the two guides (5a, 5b), for delivering the glue that is applied to the edge of the first and last sheet in the vicinity of the spine of the volume.
  • each of said delivery cylinders (3a, 3b) there is an on/off mechanism or valve (or shutter) (4a, 4b) for enabling/preventing the flow of glue coming from the tank (1) through the base (2).
  • Figure 3 schematically illustrates one said delivery cylinders (3a, 3b), showing a preferred embodiment of said on/off valves (4a, 4b).
  • the delivery cylinder (3a, 3b) contains a further inside cylindrical tube, hereinafter called a shutter (4a, 4b), coming up against the inside of the slots or holes (3ac, 3bc) in the delivery cylinder (3a, 3b).
  • the wall of said internal shutter (4a, 4b) has holes or slots (4ac, 4bc) of similar size, shape and arrangement as the holes or slots (3ac, 3bc) in the delivery cylinders (3a, 3b).
  • Each internal shutter (4a, 4b) extends from the corresponding delivery cylinder (3a, 3b) on the side opposite the tank (1) and base (2), and said extremity is closed mechanically.
  • Lever mechanisms and/or electromechanical or pneumatic mechanisms are attached to the extremity of the shutter (4a, 4b) extending from inside the cylinder to enable a partial rotation of said internal shutter (4a, 4b) around its central axis.
  • the holes or slots (4ac, 4bc) in the internal shutter (4a, 4b) are brought into or out of alignment with the holes or slots in the delivery cylinder (3a, 3b).
  • the glue under pressure in the tank (1) and flowing in the delivery cylinders (3a, 3b) may or may not pass through the holes or slots (3ac, 3 be, 4ac, 4bc) in the internal shutters (4a, 4b) and delivery cylinders (3a, 3b).
