Definitions

  • Such machines have three knives, one front blade and two side blades, which are moved with independent movements.
  • the usual practice in the art recommends that the trimming at the sides should be carried out first and, then, the front trimming.
  • This re "quirernent obviously stems from'the fact that, if front trimming were carried out first, the pile or ream might become misaligned and the operator would be compelled to square the ream a-gain prior to carrying out the'side finishing.
  • Such machines are always equipped, moreover, with a paper-pressing device that descends'with a slight advance with respect tothe descent of the side blades and.
  • the introduction of the pile isthe operation that determines the release of movement of the cutting membegs.
  • the front'blade rises, returns back to its upper dead point ,and stops.
  • the blades do not function ,againuntilthecarriage return at its end of travel for the introduction of another :
  • the cutting of a pile comprises the following stages.
  • t is another object of the present invention to provide a mechanism adapted to provide ajfeed pathjfor a carig; hich is slidably movable on guides, toenable of said carriage during a certain predeter ed of time, to provide a return' mov em"ent of and to enable halting of said carriageduring predetermined interval of time, whic maybe different frornthe "first halting time duration, andto'repeat cyclicallythe operations just recited, any number of timesfatwil l.
  • Fig.1 represents a longitudinal section of the case containing the mechanism of theinvention
  • Pi 2 is a representation partly in s'ectiontaken along ris tion partly in elevation;
  • I Fig. 3 shows how the movement of the mecha "g m age
  • An electric motor is provided'for transmitting ⁇ movement to a pulley, as shown'in Fig.1, by' inea f belts.
  • a ge ar is connected to the pulley and thioiggh-a clutch means and a suitablegearing'arrangem tAS of keeping the carriageat Standstill'during the timene transmits rotary movement to the shaft 31 which parallels the shaft 40.
  • the shaft 31 is disposed parallel with the shaft 5.
  • Fixed on the shaft 31 is the plate 27, the sector gear 26 and the sector disk 25. Fixed on the shaft are the star plate 24, the sector gear 23 on one side and the disk 4 with the button on the other side.
  • the continuous rotary movement of the shaft 31 is translated into a movement of intermittent rotation by the shaft 5, the shaft 5 having its rotation interrupted by two halting periods.
  • the button 10 is provided to travel in an arc of 180, to stop for a short period, and then travel over another arc of 180 and stop for a period of longer than that of the preceding stop. This operation is repeated .cyclically.
  • the kinematical problem to be solved is to transform the continuous rotary movement of shaft 31 into a movement of rotation interrupted by two halting periods of the shaft 5: in other words, the button 10 is wanted to travel over an arc of 180, to stop for a short period, to travel over another arc of 180, to stop for a period longer than that of the preceding halt, and so on repeating these operations cyclically.
  • the shaped plate 27 is composed of two parts or wings of sector shape equal to each other and the axes of symmetry whereof are radial with respect to the center of the shaft 31 and form an obtuse angle. From Fig. 2 it will be noted also that on the ends of each of the two arcs of the plate 27 there are fixed two studs. In Fig. 2 the studs are designated with 28, 28', 28", 28", according to the order with which they follow one another in plate rotation.
  • the stud 28 penetrates into the first eyelet of the plate 24 and pushes it in rotation. As soon as the stud 28 is going to leave the first eyelet, and this takes place when the stud 28 has surpassed in its travel the axial line that connects the centres of the shafts 5 and 31, the first toothed sector rigid with the wheel 25 engages with 'the corresponding toothed sector 23 rigid with the plate 24 which continues rotating. When the teeth of the toothed sectors are going to disengage, the stud 28 pene' trates into the second eyelet of the plate 24 and pushes it to complete the rotation of plate 24 by 180. From what has been stated hereinbefore, a rotation of the star plate by 180 is obtained according to the following succession of movements:
  • the second wing of the shaped plate 27 comes to act, which carries the studs 28" and 28' and under which is placed a toothed sector equal to that provided under the first wing carrying the studs 28 and 28'.
  • the succession of movements as already described is repeated, there is a new rotation by 180 of the plate 24, until the sector K comes to find itself at contact with the corresponding curved portion on the plate 24.
  • the length of time during which the sector K is at contact with the corresponding curved portion on the plate 24, represents the haltlonger than the one corresponding to the sector H-for loading the pile of books on the carriage.
  • Means is then provided for transforming the continuous movement of a rotary shaft into a composite rotary movement, formed by a rotation by 180, a short halt, a second rotation by 180 and a longer halt, of a second shaft.
  • the carriage is slidably mounted on guide and whereon it can slide: it will be noted from Fig. 3 that the carriage is inclined with respect to the horizontal.
  • crankpin 10 is pivoted on a small adjustable con necting rod. 12 and the latter in turn is pivoted 'on the Oscillating arm 16 at a point, 15, The crankpin 10 in its rotation drags along with it the arm 16. It has been seen that by virtue of the. mechanism represented in Fig. 2, the crankpin 10 achieves two rotations by 180 intermeaning' by pauses: the same will happen now withthe carriage C since the arm 16 in oscillating also will drag along with it the carriage. Hence the latter will perform the feed travel, halt for the time necessary for cutting and unloading the trimmed pile, perform the return travel, halt for the time necessary for'loading the new pile to be. trimmed, and so on. Now with particular reference to Fig. 4, the braking device will be described that serves .to rendereasier the movement of the shaft whereon the star plate 24 is mounted,
  • the shoe brake 112 the free end of the lever of said brake being COl'l'! trolled by the cam 117 Said cam is mounted on the shaft 31 and as is seen in Fig. .4, it provides two braking stages and two positions of disengagement: the duration of the stages of braking corresponding to the halting time wanted.
  • the spring 118 is fitted over the tie rod 118 and rests at one end against the stirrup 115 and at its other end against a nut screwed onto the free threaded end of the tie' rod 118. It is thus possible to adjust the tension of the spring at will.
  • the brake shoe 113 acts upon the grooved pulley 109 fitted on the shaft 5.
  • a mechanism for automatically controlling the introduction and discharge of paper piles in a trilateral cutting machine comprising a reciprocating carriage adapted to support the paper piles, an intermittently rotating operating means, means operatively connecting the intermittently rotating operating means with the carriage to translate such intermittent rotation into intermittent reciprocatory movement of the carriage, a continuously rotating driving means and means connecting the continuously rotating driving means to the intermittently rotating operating means so as to produce the intermittent rotation thereof, said continuously rotating driving means including a rotating drive shaft, said intermittently rotating operating means including a driven shaft parallel to the drive shaft and said connecting meansincluding a plate circumposed on the driving shaft and formed of two sectors arranged at an obtuse angle relative to each other, said sectors having arcu-ate peripheral portions provided with teeth, a stud provided at the end of each peripheral portion and extending laterally from the sectors, a disc circumposed on the drive shaft and arranged coaxially with and fixed to the'plate and having two smooth sectors arranged in the spaces between and on the same radius with the toothed portions of the sectors, a star plate circumposed on the driven
