Definitions

  • the present invention relates to a device for binding sheets by heating according to the preamble of claim 1.
  • a device of this type is known for example from DE-A-38 05 996.
  • This device includes a base plate and a housing.
  • the housing has a table surface, in the rear part of which there is an opening in order to be able to insert one or more envelopes until they come into contact with the heating plate.
  • the opening is delimited at its rear edge by a fixed rear support member and at its front opposite edge by a front support member which can be displaced in parallel.
  • the slidable organ is bent to form a horizontal part that is in the immediate vicinity of the underside of the table surface.
  • This horizontal part of the support member carries a handle which protrudes above the table surface through slots provided therein. Openings for signal lamps are also provided in the table surface.
  • a pair of rails for mounting the displaceable support member is fastened in the base part. On its bent horizontal part, this has two parallel flanges that run in the rails. The edges of the flanges are covered with slightly sliding material, for example in the form of a Teflon tape.
  • the bottom part also carries a heating plate.
  • the opening can be partially closed by the horizontal part of the vertical support member.
  • This horizontal part moves a movable magnetic core in a stationary coil to produce an output signal which indicates the respective width of the opening.
  • Such devices can be used in an excellent manner for the production of book covers, brochures and the like or for similar work, in that the back of a loose-leaf stack is glued using a thermoplastic adhesive under heating against the back of a folder, the sheets from Paper, cardboard, plastic and / or the like can be.
  • Such devices are of course also suitable to enable the gluing of two or more sheets under themselves and / or with the back of a pencil case.
  • the known device of this type is quite complex, and it is therefore an object of the present invention to improve such a device.
  • the base part 1 basically consists of a bottom part 1 and a cover part 2, which form a unit.
  • the base part 1 comprises a base plate 3, on which an elongated heating device 4, for example a rail provided with PTC circuit boards, is arranged, which has an upper elongated flat side in order to be able to support the back of the integration thereon.
  • the rail 4 extends almost over the entire length of the base plate 3 and approximately in the middle thereof. Behind the rail 4 in the left half of the bottom plate 3, a printed plate 5 is mounted vertically thereon.
  • the plate 5 is provided with a transformer 6, an electrolytic capacitor 7, two integrated circuits 8 and 9, a sound emitter 10 and a plug device 12 connected with a cable 11.
  • a holder 13 for two so-called reed relays 14, 15 is mounted on the base plate 3.
  • a holding strip 16 is mounted on the base plate 3 such that the level of the surface of the holding strip 16 is one Forms angle W with the base plate 3.
  • the holding strip 16 serves to hold a switch 17 and a plurality of light-emitting diodes or other display elements 18.
  • a switch-on device 19 which is provided with a sprung actuating element 20.
  • the holding strip 16, the reed contacts 14, 15, the switch-on device 19, the heating elements under the rail 4 and a plug connector 21 can be connected to the printed circuit board 5 via various cables.
  • 1 has the shape of a truncated pyramid with a deep slot-like opening 22 from top to bottom, such that the leaves to be bound can be inserted through this opening until they stand on the rail 4 with their backs.
  • the front wall 23 of the truncated pyramid is preferably inclined inwards at an angle W, while the rear wall 24 is directed practically perpendicular to the floor.
  • the rear wall 24 and the right side wall 26 are only indicated because they are invisible.
  • the upper edge of the wall 24 (FIG. 3) is connected to a support wall 27, which serves to delimit the slot-shaped opening 22.
  • the walls 24 and 27 form a small angle W '.
  • the plate 5 is in the assembled state in the space between the walls 24 and 27.
  • the lower part of the wall 27 has a small opening, so that the actuating element 20 is partly in front of the wall 27 in the space of the opening 22, while the Device 19 is otherwise housed behind the wall 27.
  • a folding wall 28 is pivotally mounted in the interior, which is pressed backwards by a spring, in such a way that the lower area of the folding wall 28 touches the lower area of the wall 27 or a holding plate 29 which can be moved tangentially thereon or can touch.
  • the folding wall 28 is preferably trapezoidal due to the pyramid-shaped configuration of the cover part 2, it can have a triangular flap on the right and left, which can also be pivoted and sprung.
  • the right flap is designated 30 and the corresponding hinge 31, 32, 33.
  • a magnet preferably a transversely magnetized ferrite magnet 34, is attached to this flap 30 or in solidarity with the wall 28, which moves with the wall 28 in order to actuate the reed relays 14 and 15.
  • the front wall 23 has an opening for the bar 16 as such or only for the elements 17 and 18 mounted on the bar.
  • the pyramid-shaped cover part 2 has preferably 4 beveled edges, such as edge 35 (Fig. 1).
  • the cover part 2 can also comprise a base part 36 all around.
  • the device according to Figures 1 to 3 works as follows: When the device is switched on, for example, the electroacoustic transducer or sound emitter 10 and / or one of the light-emitting elements 18 can emit an alarm signal, namely during the time ta that the device needs until the rail 4 has warmed up.
  • the time ta can be 3 minutes.
  • the sliding holding plate 29 can be pulled out upwards (according to arrow 37) in order to hold the leaves or the like better. If the leaves are relatively short, this operation is not necessary.
  • the leaves When the leaves are inserted into the opening 22, they activate the actuating element 20, which is shown in FIG. 2 as a microswitch, but which could also be an optically acting element. Due to the pressure of the leaves, the microswitch 20 disappears behind the wall 29; at the same time the wall 28 (according to arrow 38) is pushed to the right. Thus the back of the sheets or other documents can be supported on the rail 4.
  • the wall 28 pivots to the right in the direction of arrow 38, the thicker the leaf beige or the stack.
  • the magnet 34 can thus assume different positions with respect to the reed relays.
  • the magnet can not affect any Keed relay or only the first (14) or both (14, 15) or only the second (15) or (34 ′).
  • the electronic circuit is provided with an appropriate memory, it can discriminate five positions or stack thicknesses and after five corresponding times emit an acoustic and / or visual alarm signal which indicates the end of the heating process.
  • first reed relay 14 is 15 to 20 mm thick and the second one is 40 to 45 mm thick Reed relay 15 is activated.
  • the device If the user does not pay attention to the corresponding alarm signals after heating or after the binding process has ended, the device emits a further alarm signal or extends the alarm signals or signals emitted during a time which may be 45 minutes, for example, until the heating elements are automatically switched off become.
  • the heating elements are, for example, as in the case of EP-0379 838 A1 Known device arranged, but preferably in duplicate, that is, in two parallel slots on the lower side of the rail 4.
  • the spring that pushes the wall 28 to the left in Fig. 3 should not be too strong, so that the leaves only held loosely, but not pressed sideways in order not to impair the capillary action of the liquid adhesive.
  • a so-called Hall probe could also be used.
  • the combination magnet / reed relay could also be replaced by an electro-optical device.
  • the switch-on device 19 could also work on the electro-optical principle.
  • a pivotable wall 28 which consists of a relatively thin trapezoidal plastic sheet with recesses 41, which are provided to lighten the weight of the wall.
  • the wall 28 has some ribs 42 to increase the rigidity of the wall.
  • the plastic sheet On the oblique sides of the trapezoid, the plastic sheet has an extension in the form of a thin, narrow wall 43, 44, which are arranged approximately perpendicular to the plane of the sheet 28 and serve as holders for hinge elements 45, 46 and 47, 48.
  • the wall 28 On the short side of the trapezoid, the wall 28 has further hinge elements 49, 50 which are used for the pivotable mounting of the wall 28 in the upper inner region of the wall 23.
  • the hinge elements 45, 46 and 47, 48 are used for pivotable mounting of a flap, such as flap 30 in FIG. 3.
  • a flap such as flap 30 in FIG. 3.
  • a flap as shown in FIGS. 5 and 6, consists of a triangular plastic sheet 51 with two Ribs 52, 53 protruding from the blade 51 to form an area in which the hasps or clamps 54, 55 are present which allow the blade 51 to pivot.
  • a rod 32 (FIG. 3) can also be used.
  • the magnet 34 can preferably be mounted below the lower rib 53 (Fig. 5, 6).
  • the bottom part 1 and the cover part 2 can be assembled, for example, with the aid of screws or clamping elements, not shown, to form a unit.
