Description

In the case of printing punch card machines, it is known to automatically switch steps of different to the paper tape for receiving the print recordings Length to be granted, depending on the particular operating case. But it can also be used when editing of counting cards (punch cards) sorted by groups regardless of the usual line feed, which also in known machines optionally different extent in connection with can be given to the item printout and with the totals printout, when changing groups at the end the card groups made additional, particularly large paper circuits to an extent be that the total print for a card group from the first item print for the next Card group is moved so far that the paper strip is subsequently placed between the individual groups related printing can be divided into separate sheets, z. B. Invoices can form, which are provided with a head print above the first item. It is now desired, the size of this additional paper circuit that was previously set by presetting the machine has been set to change automatically during operation.

This need is satisfied that according to the invention the amount of additional Paper feed when changing card groups

by one in any or all of the cards in each group of cards intended special S expensive hole is determined according to its type, z. B. its position in the card column, a preset when the cards pass through the machine of the switching path of the paper circuit desired for the group of cards concerned, while the paper circuit itself only in connection with the card group change in the preparation corresponding extent takes place.

In itself it has already been known to produce different sized paper circuits through a series to effect from the stroke of the paper switching element limiting stops, which from under card hole control standing magnets can optionally be made effective.

The present invention is the

possibility of use for the device causing the additional paper feed is essential expanded in that it can be adapted to the respective need without difficulty.

In principle, it is sufficient if one card in a card group, e.g. the first card in the group, has the particular control hole on which a paper transport controller for preparation a paper transport of a certain extent to be carried out during group change. In general, it will be in the interests of the uniformity of the card holes, however recommend all cards in a group evenly with the particular control hole in the same place to provide. As the extent of the paper circuit when changing groups, governing organs can especially with punch card machines Hollerith type, in which the cards are in motion are electrically sensed, several electromagnets are used, which are connected to the sensing of the control holes Sensing organ. can be connected via a power distributor that connects to a certain magnet only effective for a hole located at a certain counting point makes, wherein the paper switching element is moved by a linkage that after each total pressure is put into action.

To explain the invention in more detail, it is used in a tabulating machine Hollerith design with automatic card group control device, as it is, for. B. from the Patent 479 875 can be seen in the drawings illustrated and described below. In this case it is taking effect the current paper circuit to the presence of a card hole at one of several counting points a certain column of a card, it being assumed that this card is the first of the group is.

In the drawings, an embodiment of the invention is shown.

Fig. 7 is a circuit diagram of the new paper switching device.

The control of the tabulating machine, its tape-shaped recording sheet by means of the device is to be advanced according to the invention, takes place in the usual way by counting cards of the type shown in FIG. The counting cards are transported through the machine by pairs of rollers, as indicated in the circuit diagram in FIG. Through the Pairs of rollers are the cards one behind the other at two sensing points with contact brushes 12 and 13 passed by. In connection with the transport of the counting cards, a shaft 11 rotates, which makes one cycle for each counting card that passes the sensing brushes.

It is assumed that the counting cards to be processed are sorted into groups in the usual way and that each time a group of cards has passed through, a sum is drawn · and is printed on the recording sheet, which is also printed on the passage of the individual cards who receives items punched in the cards. It is necessary every time to carry out the item printing a line feed of the paper tape.

The items are printed under the control of those who sense the post holes in the cards Brushes 13, each of which when it hits a card hole create a circuit for a print magnet 14 (Fig. 1) closes so that it is excited. At the same time synchronous with the movement of the Counting cards past the brushes 13 there is an adjustment of the type carrier with respect to the paper roller 16, so that when you feel a certain card hole by a brush 13 each time the The type corresponding to the card hole is in the printing position opposite the paper roller 16. The excitation of the pressure magnet 14 fixes the type rod 15 in the usual way Release of a pawl 18 for engagement in the toothing 19 of the type carrier, wherein the release of the pawl 18 by triggering a pawl 17 under the influence of excitation of the magnet 14 takes place. After each time the scanning of a card 10 has been completed by the Brushes 13 takes place in the usual way, the stop of the print hammer 20, so that the pressure point located Types come to the imprint, whereupon the type rods 15 again in their basic position be returned to under control of the

The perforation of the next counting card is set again when it passes the brushes 13 will.

The paper circuit takes place in the usual way with tabulating machines. That purpose serving device is illustrated in FIG. Since the facility is known, it is only necessary here a brief description of their interaction with the paper switching device according to FIG Invention to make clear.

With 305 an oscillating shaft is referred to, on which an arm 21 sits, which at its upper End of a pin 22 carries. When the shaft 305 oscillates clockwise executes, then the pin 22 lies against a shoulder 23 of a lever 24, which to a from the parts 25 and 26 existing lever connection belongs. The part 25 is rotatable placed on a pin 27 and articulated to the lever 24 at 28. Levers 26 and 24 are at their left ends at 26 "or 24" adjustable connected to part 25. The parts 24, 25 and 26 take effect once they have been set to each other as a unified whole and are driven by the shaft 305.

With the lever 25, a link 29 is connected, which with its free end on the ratchet arm engages a switching mechanism 30, the ratchet wheel is coupled to the paper roller 16 so that the Paper roller is given a line break by each oscillating movement of the shaft 305, the before each item is printed.

After each time a group of cards has passed through the machine, in tabulating machines usually a device for the automatic total pull effective. The making of the effect for the sum move takes place under the influence of a change of the simultaneously by the Brushes 12 and 13 sensed group identification holes, whereby a comparison of the group identification holes of successive cards comes about with one another comes.

According to the illustration in FIG. 6, the card column carrying this control perforation is the first Column of the card, and the tax hole is in the ninth meter point position of this column. the The machine is arranged to give various indexing movements to the recording sheet under the influence of tax holes in the aforementioned special column is able to issue, ever after the column in the ninth metering point position, as shown in FIG. 6, or in the eighth or in the seventh is punched.

As can be seen from Fig. 7, the brush 12, by which the card is first sensed, in the presence of a hole in the one it sensed first card column in contact with a contact bar 31, which has a Cam contact 33 in connection with the main current conductor 32 of the electrical power source of the Plant stands. Contact 33 is used during the sensing period of the counting point locations of the cards kept closed by the cam. The brush 12 is connected to a segment 34 of a power distributor conductively connected, which is ground by a brush 35 during the sensing period of the Cards. A brush 36 is conductively connected to the brush 35, which is used during the card sensing period the contact pieces 37 looped.

When the ninth counting point position of a card is sensed, the brush 36 is located a little to the right of the position in which it is shown in FIG. 7, so that it is in contact with the first contact piece 37. So if a card goes through the machine which has a hole in the ninth metering point of the first column of cards sensed by the brush 12, there is a power connection from the conductor 32 via the contact 33, the contact bar 31, through the card hole at the ninth metering point, the brush 12, segment 34 with the contact piece 37 sensed by the brush 36, which in turn is connected by a current conductor 39 to the winding of an electromagnet 38 and to the second main conductor 44. Just like the mentioned contact piece 37 adjacent to the contact segment 34, which is in contact with the brush 36 when the ninth metering point in the first column is sensed, the two adjacent contact pieces 37, which are in contact with the eighth and seventh metering point positions when the eighth or seventh metering point is being sensed, are also mentioned the brush 36, connected to the main current conductor 44 via current conductors 39 and magnet windings 38. If there is a hole in the eighth or in the seventh counting point position, a magnet 38 is likewise excited by the brush 12 when this hole is sensed. In addition to the contact 33, a contact 40 is also controlled by a cam seated on the shaft 11. This cam is arranged on the shaft that it also closes its contact 40 during the duration of the sensing of the counting point positions by the brushes, so that at this time the main current conductor 32 via the contact 40 has connection to a contact 41, which by excitation of the The electromagnet 38 assigned to it is closed, which in turn is connected to the main current conductor 44 via the winding of a holding magnet 42 for the magnet 38. When excited, the magnets 38 also close contacts 43 which are connected to the main current conductor 44 via a cam contact 45. The cam contact 45 is closed each time before the cam contact 40 opens, and remains closed during the opening period of the cam contact 40. Each contact 43 can be connected by a plug connection 46 to a stroke limiting magnet 47 and a holding magnet 57 for the latter. Corresponding to the three contacts 43 there are also three pairs of magnets 57, 47, the latter being distinguished from one another by one of the letter indices a, b, c. When one of the contacts 43 is closed, the magnet 47, 57 connected to the contact by a plug-in cord 46 is connected to the main current

ladder 44 brought. The windings of the magnets 47 and 57 are also on the cam contact 48, which is under surveillance by a cam seated on the AVelle 11, in connection with the main conductor 32. The contact 48 is closed during the same time during which the contact 45 is closed, and remains also at the end of the metering point sensing period for the last card of the group closed. The contact 40, however, opens before the last card one Group is sensed, whereby the holding magnet 42 is de-energized, and since that time at the Cam control standing contact 33 is open, ■ the selected relay magnet becomes ineffective, and the contacts 41 and 43 assigned to it are opened.

The contact 45 is opened prior to the completion of each card-related machine game. However, if the stroke limiting magnet 47 is energized, then the contact 49 of it is assigned Holding relay 57 closed, thereby maintaining the energization of the selected stroke limiting magnet will.

In summary, it can be said that after the last card in a group has passed through the brush 13 was sensed, then under the control of the brush 12 of the first card of the next one Group of one of the magnets 38 and the holding magnet 42 assigned to it are excited. But since the Group control device interrupts the tabulation drive, the cam contact 45 does not come more about the effect.

The cam contact 48 also remains closed, and the magnet 47, which is still excited, is also kept closed by the holding contact 49 of the holding relay 57, since the shaft 11 also comes to a standstill. Now the sum shaft is set in rotation in order to bring about a sum train. This sum wave is designated 315 in Fig. 7 and brings about the closure of a contact 51 after a sum has been printed under the control of the adder of the machine. The closure of the contact 51 causes a paper solenoid 52 to be excited. As can best be seen from FIGS. 1 and 4, the paper roller 16 is seated on a shaft 53 on which a peeling wheel 54 is attached, in which a pawl 55 engages. The pawl 55 is seated in an articulated manner on an arm 56 which is loosely placed on the shaft 53. The pawl 55 is resiliently held in engagement with the teeth of the ratchet wheel 54 in the usual way, and after the arm 56 has been turned clockwise to switch the wheel 54, the arm 56 is returned to its basic position by a Feather! 5 7 returned. A link 58, which is connected to a rod 59 made of magnetic material, engages the upper end of the arm 56. The latter penetrates a hole in a frame plate 60 and projects with its right-hand end partially into the inner part of the paper switching magnet 52. When the magnet 52 is excited, the rod 59 is pulled into the magnet winding to the right (FIG. 1). The rod 59 is provided with lateral notches 61 and 62, which form stop surfaces 63 and 64. Each of the cap limiting magnets 47 for holding cardboard, e.g. B. in the representation of Fig. 2, the magnet 47 ^ pulls> when it is excited a pair of iron cores 65 into calibration, which sit on two levers 66, which are rotatably mounted at 67 in the frame plate 60. And are moved against each other like scissors .

It should be remembered at this point that when the first counting card 10 of a new group is removed, one of the control magnets 47 is excited and remains excited after the total printout has taken place. If this magnet is the magnet 47 ^C , which is farthest to the right according to the illustration in FIG 52 is moved to the right.

The contact 51, which can be seen at the bottom in FIG. 7, is formed by the cam seated on the shaft 315 closed after every press. Since at this point in time the magnet 47 is already is excited, the rod 59 performs a pivoting movement of the arm 56 and by means of the pawl 55 (a switching movement of the ratchet 54 and daimiit also the paper roller 16, its size is determined by the thereby excited stroke limiting magnet 47.

The switching movement of the paper strip is smallest when the magnet 47 ° is excited, the lever arms 66 of which interact with the shoulder 63 of the rod 59. The magnet 47 ^C causes a somewhat larger switching movement of the paper roller, the shoulder 64 of the rod 59 serving as a stop for limiting the movement of the rod 59 when it hits the scissor arms 66 assigned to ^{the magnet 47 s.}

The greatest screeching movement that can be imparted to the paper tape takes place under the control of the magnet 47 *; When this magnet is excited, the stopping movement of the rod 59 is limited by the impact of its shoulder 63 on the scissor arms 66 actuated ^{by the magnet 47 s}

Although the device described is fully operational, it is advisable to provide suitable means to brake the movement of the rod 59 which is caused by the excitation of the magnet 52. For this purpose, the rod 59 is stranded at its right-hand end with a brake core 68, which carries an extension 69 with a tapering end, which is able to close contacts 70 ", 70 ⁶ , 70 ^. When the magnet 47 ^{0 is} excited then causes the brief movement of the rod 59, which occurs in connection with the fact that the indentation 69 closes the contact 70 ° when the rod 59 approaches the end of its advance

the influence of the magnet 47 ^C closes the contact yo ^c and with the greatest displacement movement of the rod 59 closes the contact yo ^b .

As can be seen from Fig. 7, the one spring leaf of the contacts 70 °, 7ο ⁶ , 70 ^{c is} connected by a wire 71 to the main conductor 32, while the other spring leaf of each contact by a wire J2 with a contact 73 ^a or 73 ¹ 'or 73 ^{C is} connected. Each of the contacts 73 ". 73 ^& , Tb ⁰ has a connection to a wire 74 which leads to a resistor 75 which is connected in series with a brake magnet 76. The magnet 76 is connected to the second main current conductor 44 by a wire 77. The circuit just described reveals that when the rod 59 executes its smallest movement and then the contact 70 "closes, then the contact 73" is also closed and that the greatest resistance is then connected in series with the brake magnet 76 , while at Closing of the contact 7o ^& in connection with the greatest displacement of the rod 59, the contact 73 ^{& is} closed and switches on the smallest resistance in the braking magnet current.

The embodiment of the magnetic brake is illustrated in Fig. 4, where the solenoid 76 of the Brake is inserted into an annular cavity 78 of a plate 79. The brake winding 76 protrudes also into an annular cavity 80 of a cover part 81, which is displaceable, but seated on the shaft 53 secured against rotation by a wedge 82. When the solenoid 76 is excited, then she pulls the cover part 81 against

a collar of the plate 79, so that the rotational movement of the paper roller 16 in its last part is braked.

The brake winding 76 is most effective when the rod 59 is in its greatest displacement

experiences, so that the highest braking effect then comes about while the effect is less with a smaller displacement movement of the rod 59. The setting of the braking effect takes place by a suitable connection of the current conductors 74 to the resistor 75.

After the magnet 52 has been excited and the rod 59 has experienced the desired displacement movement, the contact 51 is opened, so that the spring 57 is able to return the rod 59 to its basic position. On that if the tab motor is switched on again, see above that the shaft 11 begins to rotate while the sum shaft 3i5 is stopped. The cam contact 48 is opened first and interrupts the holding circuits of magnets 47 and 57, see above that these return to the initial position. This is followed by the cam contact 45, which, like has been explained earlier, via contact 43, one in the group change by sensing the first Card of the new group through the brush 12 energized relay 38 the corresponding stroke limiting magnet 57 excited, which now remains excited until after the sum move at the end of the new one Group the additional paper circuit is done and the table work for the new following Card group begins.
