Definitions
- the invention relates to a device for supervising the regular transportation of the cards in a card controlled business machine.
- a safety device is actuated by which e. g. the machine is stopped.
- the irregularities in the transportation of the cards can be caused by a lateral displacement of the cards from the guide-track owing to irregular working of the transporting rollers for the cards, said lateral displacement causing wrong position ing of the cards arriving at the following parts of the machine.
- Such irregularities are especially objectionable in business-machines working with indication carriers, e. g. punched cards.
- punched cards In these machines the punched cards must be sorted according to certain combinations of the punched holes.
- the sorting capacity of such machines is very large,
- the main object of the invention is to provide a solution for this problem by placing a plurality of supervising devices near the track of the moving cards, which devices are moved in the direcden of transportation, when one or more cards are displaced out of their normal track and by this movement actuate a safety device, e. g. a stopping device for the machine.
- a safety device e. g. a stopping device for the machine.
- the extentof displacement of the supervising device would be determined by the extent of the irregularity. For instance if an electrical contact had to be actuated by an accumulation of cards one above the other, a certain number of cards would be pushed one over the other before the contact would be closed. In practice it has been shown, that with a laterally moving supervising device such a device must be displaced about 1 millimetre (in relation to th required distance between the electrical contacts and the inevitable play of the moving parts) which distance corresponds with the thickness of six cards of the usual material. However When a supervising device only acts when six cards are pushed one over the other, such a device is much too slow.
- the supervising device according to the invention is already moved into the direction of transportation, when only one card is pushed over a following card, causing a deviation of a fraction of a millimetre.
- the cards are normally transported along the guide path one after another in a non-overlapping condition. Consequently the normal path of these cards is determined by the width and the thickness of the cards.
- irregularities in the vertical direction e. g. any superposition or overlapping of the cards.
- detector tubes at both sides of the guide path as illustrated in one of the embodiments of the invention, a deviation sideways or horizontally with respect to the direction of feed can also be detected.
- Figure 1 schematically shows a side view of the transporting device of a sorting machine for punched cards, all parts not necessary for understanding of the invention being omitted.
- Figure 2 shows asimilar side view of a second embodiment of the invention.
- Figure 3 is a cross-section along the line IIIIII in Figure 2.
- Figure 4 is a cross section of a detail on an enlarged scale.
- Both embodiments respectively relate to the transporting section of a sorting machine for punched cards, the cards moving one following the other in the guide path indicated by the dash lines in Fig. 1.
- a supervising device is placed over theguide path and before the rolls Illa, 111b, said device being provided with an arm rotatable about a spindle 26.
- the free end of the arm 25 is pivotally connected at 28 with an arm 21 forming the supervising device proper.
- the free end of the arm 21 rests on a pin 29 fixed to the frame of the machine, said pin being adjusted in such a man ner, that the lower surface of the arm 21 is just free from the top side of the card it.
- a resilient metal arm [2 is provided, which arm is shown on an enlarged scale in Figure 4.
- a steel wire I8 is connected to this arm, the other end of said wire lbeing con nected to a screw pin M in a bow l5 fixed to the frame of the machine.
- the pin 14 is adjusted by means of a nut 16 in such a manner, that the wire 18 is tensioned by the resilient arm !2, maintaining a constant tension in the wire.
- a supervising device i1 is placed extending along the whole length of the transport track, said device for instance being formed as a tube made of a spiralized metal wire.
- This tube 11 can be easily moved along the smooth wire.
- the right end of the tube abuts against an insulating bushing it placed in an opening of the frame, said bushing being pressed against the tube by means of a spring 29 of a pair of contact springs 20,2061.
- the supervising device 11 is always pressed back 4 are placed directly over the transport track.
- similar supervising devices 110 and [1d are placed at both sides of this track.
- the sorting is achieved by moving the flaps 22 ( Figure 2) placed over the track between adjainto its initial position against the end of the arm 12.
- FIG. 3 shows that each set of transporting rolls for the cards I l comprises two pairs of rolls placed at the left and at the right, said pairs being indicated at 10a, 10b, and 100, Hid respectively. Further, two of the supervising devices already described are indicated by 11a and [1b,which cent pairs of rolls. When such a flap is turned down by electrical means, a card is pressed downwards out of the track and slides along guides (not shown) into a sorting receptacle. As such arrangements are known per se a further description seems to be superfluous.
- the tube 11 can also be made of a material with a rough outer surface or can be provided with a coating with a large coefficient of friction.
