Definitions

  • the present invention relates to a device for binding Scroll by heating according to the preamble of the claim 1.
  • a device of this type is, for example, from EP-B1-0 508 945 known.
  • This device includes an elongated electrical heater, the length of the length of an elongated opening of the Device corresponds and a switching device to an electrical Activate circuit at the moment of inclusion is placed on the heater.
  • the heating device itself comprises PTC thermistor elements and is therefore self-regulating.
  • a computer is provided with which the Width of the inserted in the opening between the support members Envelopes can be scanned and with which depending on it the switch-on time of the timer for the heating element can be set is.
  • Such devices can be manufactured in an excellent manner of book covers, brochures and the like or the like Works are used in that the back of a Loose-leaf stacks using a thermoplastic acting adhesive while heating against the back of a Folder is glued, the sheets of paper, cardboard, Plastic and / or the like can be. Such devices are of course also suitable to stick two or several sheets under and / or with the back of a pencil case to enable.
  • the device shown in Figures 1 and 2 has a base body 1 with an octagonal cross-section.
  • a cable connection 2 At the front of the Base body 1 are a cable connection 2, a switch 3 and a Control panel 4 available.
  • the base body 1 points to the upper one Side an elongated slot 5, the width at least corresponds approximately to the width of a heating device 6, which is a heat-conducting rail 7, preferably made of aluminum, includes.
  • the base body is at least two supports fixed at a distance for an elongated laterally pivotable flap 10 and a Switch 11 arranged, the via a movable pin 12 at Swiveling the flap 10 is actuated.
  • a spring 13 By a spring 13 is the flap 10 is held in an elevated position, in which the Switch 11 is not turned on.
  • the heating device 20 comprises one elongated metal rail 21, preferably made of aluminum, with a approximately U-shaped cross section, as shown in Figure 4.
  • a ceramic support 22 arranged, preferably over a relatively thin Layer-forming thermal adhesive 23 with the flat side the rail 21 is glued.
  • the ceramic carrier 22 preferably carries two via a fuse 26 resistors 24, 25 connected in series. Resistors 24, 25 have two connections A1, A2 for the heating current. On the resistance 24 is a temperature sensor or sensor 27 with two connections B1, B2 arranged, preferably at a distance from one end of the rail, which is approximately equal to 1/3 of the length is the rail 21, which has two legs 28, 29, the Leg 28 is shorter than the other. The leaves to be bound are inserted vertically in the area between the legs 28 and 29. The resistance masses are through a glass insulation 30 protected.
  • the switch 11 (Fig. 2) and the heater 20 is shown with the sensor 26.
  • the Switch 11 is via the series connection of the heating device 20 and a switch 31 connected to earth.
  • One at the switch 11 connected rectifier 32 supplies the current for two Comparators 33, 34 and for a lamp 35, preferably a Illuminated field or a red LED lamp, which over another Switch 36 is connected to earth.
  • the electronics include one OR link 37, the input side with one output each Comparators 33, 34 is connected, and their output signal for Control of the switch 36 is used. Comparators 33 and 34 are acted upon by the output signal of the sensor 26.
  • the Reference voltage input of the comparator 33 is connected to the Output of the rectifier 32 connected reference voltage circuit 38, which is preferably a voltage divider, connected.
  • the reference voltage input of the comparator 34 is on the output of the rectifier 32 connected locking circuit or latch 39 connected to the output of the comparator 34 is fed back.
  • the rising temperature curve depends on the constant mass of the rail and the mass of the inserted leaves, which can fluctuate.
  • the glue begins to become liquid; this corresponds to time T3 (signal b).
  • T3 signal b
  • T min a time at which a time T2 is a predetermined T min .
  • the comparator 33 becomes active and emits a signal "1", which is of no importance per se for the heating process.
  • the reference voltage of the comparator 34 is predetermined such that its output signal "0" and the switch 31 (signal h) are switched off at a sensor temperature T max . This corresponds to time T4 in FIG. 6. The temperature drops as the device cools naturally. As long as T> T min , the comparator 33 outputs an output signal "1" and the switch 36 remains closed, that is to say the lamp 35 burns until T ⁇ T min . Then, that is to say at time T5 (FIG. 6), it goes out.
  • the switch 31 remains open, even if T ⁇ T max , so that the heating effect only lasts from time T1 to time T4. During this time, the energy consumption (curve e, Fig. 6) is greatest.
  • the device remains switched on as long as sheets are inserted in the device remain that over the depressed flap 10 (course k, Fig. 6) keep the main switch 11 closed. After removal of the bound leaves the stream is interrupted Latch circuit loses its effect, for example by discharging a capacitor, and the process can start from Start at the beginning, with the immediately following binding the Process time or binding time becomes shorter because of the heating device is still a little warm.
  • the temperature gradient becomes correspondingly smaller due to the inertia of the system (FIG. 13), that is to say the time T5-T3 becomes longer, and the heating device 20 remains switched on longer, which is desirable given the large folder thickness; this automatically results in the necessary duration of the heating process depending on the folder thickness. Since the process is controlled via T max and T min , the binding time is automatically adjusted.
  • the energy consumption is zero during the waiting times.
  • the folder can be removed as soon as the lamp 35 is no longer burns because then the process is complete.
  • the folder may however, continue to stay in the device, for example if you use them forgets because the heating is switched off and therefore the folder cannot be damaged by overheating.
  • a narrow pivoting wall or flap 70 is provided as a cover for the elongated opening 5.
  • the flap 70 actuates a switch 71 via a lever 72.
  • a spring 73 holds the flap 70 in one closed position at the opening of the housing.
  • On the end areas an elongated base plate 74 are each a holder 75, 76, preferably attached made of plastic, with a Shoulder 77 and 78 are provided, on which the ends of the Support rail 21.
  • the Switch 71 housed with its resilient lever 72.
  • the flap 70 which is laterally pivotable between the brackets 75 and 76 is mounted, has a rounded extension 81 on, when rotating the lever 72 down presses to turn on switch 71.
  • FIGS. 8 and 9 show the relative position of the rail 21 with respect to the switch 71.
  • Figure 8 shows schematically the beginning the pivoting movement of the flap 70 when the extension 81 begins to exert pressure on the lever 72.
  • Figure 9 shows switch 71 in a closed position.
  • the flap 70 has slanted slots 82 which are provided to facilitate the passage of warm air.
  • the flap 70 is in the central region in cross section slightly arched and relatively strongly curved on the outer edge.
  • the outer surface of the extension 81 and the curved Part of the flap 70 also forms an arc in cross section Center in the pivot axis 83 of the flap 70, which is approximately located above the shorter U-leg 28 of the rail 21.
  • Another advantage of the device according to the invention is that the Input switch 3 (Fig. 1) can be omitted because of the inventive Electronics of the switch 11 or 71 are enough to to control the desired heat cycle.
  • the temperature sensor 26 does not necessarily have to be very precise. It For example, sensors known per se can be used. which have a PTC or an NTC resistor.
  • the Switch 31 is preferably a TRIAC switch.
  • Figures 10 and 11 show examples of housings with a round or square cross-section.
