Definitions

  • ABSTRACT An apparatus for binding groups of loose perforated sheets for albums, copy-books, calendars and the like,
  • the present invention relates to an automatic apparatus for binding of loose perforated sheets for albums, copy-books, calendars, notebooks, memorandumbooks and so on.
  • Binder elements are known, which are available in the trade as reels of metallic wire optionally coated with plastic materials or enamelled, or also made out of plastic materials, substantially similar in shape to an open spiral, or to say it better, a sequence of open rings connected together, or even being of the so-called comb" type.
  • the semiautomatic apparatus is characterized in that it comprises, in a housing and supporting frame, means for feeding a looped wire band from a feed reel, means for counting the number of loops of said band and for comparing such number with the number preset on an adjustable selector adapted to operate means for cutting the band, and means for inserting the cut band segment into holes provided in groups of loose perforated sheets positioned on the same apparatus at a coupling and closing station, means responsive to said positioning being provided and adapted to allow the feeding of the next multi-loop segment upon the actuation thereof due to said positioning and adapted to operate said feeding means when said responsive means is released upon the removal of said group of sheets from the coupling and closing station after the closing has been effected by said inserting means.
  • two different operations are possible, a first of which provides for the insertion of only one multi-loop segment, having a given length, for each article to be bound and a second one, particularly suitable for calendars, in which the binding operation is accomplished, for each article, along two series of peripherical holes spaced apart so that at the middle of the sheets a free space is provided in order to allow the application for example of a fastening means of the calendar to a wall and so on. In this ing operation.
  • the insertion of the binder into the perforated sheets is automatically accomplished together with the closing under the press of the binder elements
  • the coupling statically occurs by manually placing the group of sheets to be bound in a given position and by operating the press, for example by means of a foot control lever on the same group of sheets.
  • FIG. 1 shows a perspective diagrammatic view of the apparatus according to the present invention
  • FIG. 2 shows a diagrammatic view of the feeding device of the binding elements
  • FIG. 3 shows a frontal partially sectional view of a de tail of the coupling and closing station of the binder elements with the perforated sheets;
  • FIG. 4 shows a sectional view taken along the line v lV-IV of FIG. 3;
  • FIG. 5 shows a diagram of the pneumatic circuit of the apparatus according to the present invention.
  • Feeding means (shown in FIG. 2 but not in FIG. 1) delivers an open wire binding strip 2 to the apparatus from a supply reel 3.
  • Strip 2 has a generally C-shaped cross-sectional configuration and is formed by integrally-connected, parallel spaced looped prongs best illustrated in FIGS. 3 and 4.
  • a sensing device 4 counts the loops passing thereunder and compares the counted number with a number programmed on a selector included in a control panel 5. When the programmed count is reached a cutting means 6 separates the counted loops from the strip.
  • a press consisting of two metallic elements 7 and 7a is adapted to press the cut loops 'therebetween to cause the open loops to close at a coupling and closing station formed by two support shelves 8 and 8a for the sheets to be bound.
  • the strip feeding means comprises a toothed chain or belt 9 driven and guided by a set of rollers.
  • Roller 10 serves as a drive roller whereas the remaining rollers 11, 11a, 11b, 11c, and 11a are idler rollers.
  • chain 9 is diverted on two idler transmission rollers 12 mounted on a movable plate 13.
  • Plate 13 may be brought nearer to roller 11 without deviation; that is, strip 2 remains aligned with a front chain guide 9a.
  • a strip segment transferred automatically to the coupling and closing station at the end of the preceding operation cycle (or manually at the beginning of the first cycle), arrives in front of a stack of perforated sheets which has been arranged on the two shelves 8 and 8a.
  • the lower of the two open (i.e., C-shaped) ends of the loops of strip 2 is designed to pass through the perforated holes of sheets 23. Therefore the press stoke, in order to cause the coupling between strip 2 and the perforated sheets by closing the loops, should occur chiefly from the bottom.
  • the lower member 7a of the press usually has a greater stroke and/or speed than upper member 7 which acts substantially as an anvil.
  • FIG. 4 parallel to and in front of the two press members 7 and 7a there are two movable walls 20 and 20a.
  • the walls act as a front guide surface for strip 2 during the press stroke to prevent the ends of the loops from getting crushed in a position parallel to the stack of sheets by guiding the loop ends into the sheet holes.
  • the movable walls'20, 2011 close lightly to hold the loops, automatically adjusting their positions by proper elastic means (see FIG. 3) according to the thickness of the group of sheets.
  • the press opens walls 20, 200 return to their normal position.
  • microswitch 21 which senses the presence of the sheets.
  • lever 14 moves back to its initial (illustrated) position. This causes displacement to the left (in FIG. 2) of the toothed belt 9 section, between rollers 11 and 11d, resulting in a balancing of the previous displacement to the right but without affecting the positioning of the strip segments since in this situation the displaced belt section carries no binder elements.
  • the driving roller 10 moves up to bring another strip segment between rollers 11 and 11d so that the I equipment of the apparatus according to the present invention, which equipment is substantially housed inside control panel 5.
  • the operation of the circuits will be described hereinbelow with the understanding that a digital (not analog) systemis employed andtherefore the output and input voltages have strictly defined values (except for smallvoltage drops due to the loads, etc.).
  • the voltage level 0 V is indicated by 0 (logic zero) and the voltage level l2 V dc. by. 1. (logic one), the meaning of which is well known in digital electronic language.
  • a pulse is produced by the photoelectric cell 4 (FIGS. 1 and 3) through suitable slits formed on the driving roller 10.
  • These pulses reach the 0 input of block AU which operates as a feeder for the two decade counting devices DUI and DU2 and further as a filter and squaring device for the counting pulses.
  • the pulses From the output 4 of the block AU the pulses reach the input of the first counting decade, i.e., of the first decade block DUl, from which the pulses, from number 0 to.9, come out coded through the outputs 6, 7, 8, 9 respectively.
  • These outputs are connected with the inputs 6, 2, 7, 4 of the coding section relating to the first decade of a numerical selector S.
  • Each tenth pulse counted at DUI is sent from output 2 to the input 3 of second decade DU2 where the pulse is counted in the same manner as in the first decade.
  • the switches in selector S are manually set to the number corresponding to the required number of loops of a binding segment. When the selected count is reached, output 3 of the selector S provides a logic 0.
  • the output 3 of selector S is connected to pin 4 of inverter N3Z which drives input 1 of the memory ML3. The latter switches and causes its output 0 to be switched from 0" to 1, whereby the motor stops and the brake isapplied through the static switches J 1F and JOM.
  • the cutting operation occurs at the end of each feeding cycle through the above described actuations.
  • the cut may be also provided through the double manual operation (closing and subsequent opening), of the cutting push-button D on the front side of the control panel 5 (see FIGS. 1 and 6), but only when the motor is at rest.
  • the output 0 of the block ML3 becomes logic l and therefore the output 4 of the same memory block goes to logic 0 since the outputs of the ML blocks are complementary.
  • This logic 0 reaches the input 2 of block NEW and enables the actuation of static switch I 1P relating to the operation of the press.
  • the press foot lever 22 see also FIG.
  • the total operating cycle as described from the setting of the switch A on the contact 1 and so on, may also occur through the micro switch 21, since its contact opens when the sheets to be bound are placed in the insertion zone, and closes again when the bound sheets are removed from said zone as above described.
  • the advantage of this operation is easily understood since the feeding of the new binder elements occurs during the time in which the apparatus operator stores the bound sheets and takes the next group of sheets to be bound, with no idle time.
  • the switch A has to be set in position 2.
  • input 2 of block N2 receives logic level, as do input 7 of block N3X and input 8 of memory MLl.
  • These logic levels result in a change of the operation as so far described.
  • This change resides in the fact that, at the end of a feeding cycle, besides performance of the cutting operation, the static switch J 15 is also enabled. This excites the magnetic valve E15 thus pushing the lever 14 through piston 15. This results, as above mentioned, in the sliding to the right of that binder segment, which is between the pulleys 11 and 11d.
  • the second binder section consisting of the same number of loops as those of the first section, but spaced therefromby a length depending on the layer 14 displacement, is drawn forward.
  • the spacing device 15 be retracted back into the cycle starting position. Specifically, the logic l level at the output of block MS2 reverses the logic level at output 4 of block ML2. Therefore at the input 8 of block N3X the logic balancing is destroyed and then output 9 of N3X assumes a logic 0 level, i.e., the static switch J 15 is cut off and spacing cylinder 15 is retracted.
  • the apparatus If the apparatus has to be adjusted, it is necessary that the brake be unlocked without starting the motor. This is met by positioning the switch C on the front of the control panel 5, into brake unlock position, i.e., by closing the switch C of FIG. 6. In this way, a logic l level is obtained at the input 8 of the block N2 and therefore the cut off of the static switch JOM is also obtained. The logic l level reaches the input 2 of static switch J 1F and excites the circuit for unlocking the brake.
  • the blocks AC of FIG. 6 are d.c., known devices.
  • a semi-automatic apparatus for binding loose sheets perforated along one edge comprising:
  • a feed reel for storing a wire band configured as a series C-shaped loops
  • feed means for feeding said wire band from said feed reel along a predetermined feed path

  • control means responsive to absence of predetermined positioning of said sheets at said coupling station for inhibiting. operation of said press means, and responsive to removal of a stack of sheets from said predetermined positioning at said coupling station for re-initiating wire band feed by said feed means.
  • said feed means comprises a toothed belt driven by various pulleys, one of which is a driving self-limiting pulley.
  • An apparatus according to claim 2 further comprising:
  • said driving pulley is provided with slits on its upper surface for each loop drawn by said toothed belt
  • said counting means comprises a photoelectric cell mounted near said driving pulley for sending a pulse for each slit of said pulley.
