Description

Group control device for tabulating machines with perforated Register card-controlled tabulating machines, automatic group control devices are used, in order to offset the number of cards running through the machine in the event of a group change interrupt and, if required, initiate an automatic total printout. The groups are thereby assigned identification perforations through the value perforations of the cards determined so that with the help of the automatic group control for all cards the assigned group result is obtained with the same identification perforation. Included The group control is of course always only a certain, limited number monitored by registration columns, namely the identification columns, in accordance with the requirements whose perforation the group results are to be formed. Everyone to be monitored Column is assigned a control element and the number of required Control elements within moderate limits, d. H. within the practically occurring To keep the maximum number of group control columns, one has the group control device made adjustable in such a way that the group control elements with the A. Registration columns can be connected. Plug connections are used for this purpose, through which the control elements of the group control to the sensing organs of the group columns on the card. Another suggestion is the connections Adjusting member carrying the control elements along the sensing elements of the card set, and by means of switches the unused control elements can be ineffective be made.

The present invention now provides for one that is simpler to operate Establishment through which, above all, that of the Group control Controlled column area is set in a clear manner and if necessary can be read on a scale. The group controller n411 of the invention belongs to that Gatt4@e.a where the several are each intended for a card slot Group control elements durcji a common setting element optionally to the sensing organs of an area of adjacent map columns and for the from Control element selected column area the group control elements effective or can be made ineffective., The essential after: the invention consists of such an arrangement that on the one on the sensing members of an area of adjacent columns of cards adjustable adjusting member (z. B. a slide) another relative to him and with it adjustable adjusting member (z. B. another slide) sits, through its relative setting to the first adjustment member to the sensing organs of the selected Map columns switched on group control elements for these map columns step by step can be made effective or ineffective; according to the attitude of the two Adjustment members relative to the card columns as well as relative to each other is thus -the column area monitored by the group control according to position and number of monitored card columns determined, z. B: through the scale space between the with the adjusting members connected and playing along a scale pointers lies.

The invention also provides means for adjusting the two adjustment members inevitably towards the maximum number of existing group control elements limit so that no more registration columns can be switched on than Group controls are present. The adjustability is still made so that at least one registration column is under group control, if not, through a special switch the group control facility completely ineffective is set.

The embodiment described below is in conjunction illustrated with an electrical group control device, in which in As is known, two cards running through the machine in a row at the same time felt by two sets of brushes offset from one another and the marking perforations be compared, with the group controls in the selected columns placed between the two sets of sensing brushes. The invention can However, they can be used just as well in a group control facility using of a single set of sensors, it senses successive cards one after the other. at the use of a group control device with control magnets, which in turn Controlling control contacts is, according to the present invention, by the relative movement of the two setting members to each other the required number of control magnets automatically switched on in the group control circuit, and the unused control contacts are short-circuited at the same time.

Even if the present invention on hand ebnes for an electrical Group control device suitable embodiment, is described so its application is by no means to this type of group control device limited. It can easily also be used for a mechanical group control device Find application, with only the electrical connections by mechanical Connections replaced too - will need. With such mechanical group control devices Multiple rows of sensing pens sense the identification columns of the card and control a kind of memory device for the group control numbers. The adjusting links according to the present invention then only have to be provided with Verhindungsglie: dern-for the sensing pins be provided with the memory device, so that depending on or relative setting of the two adjustment elements more or less rows of pins with the corresponding control elements the memory device are connected.

7 illustrates the control of a control contact by means of a group control magnet. The registration cards io (FIG. I) are tapped in a known manner by a knife from a stack of cards and then guided one after the other through the machine by means of transport rollers ii. The registration gaps of the cards are sensed by an upper set of brushes 12 and a lower set of brushes 13 which are offset from one another so that the upper and lower brushes each sense the same hole positions. The brushes 12 can establish a conductive connection through the holes in the cards with a contact roller 14 and the brushes 13 with a contact roller 15. For the sake of simplicity, only 15 registration columns are illustrated in the punch cards shown, although the usual registration cards generally have more columns. The same group number 514 is punched in the 5th, 6th and 7th columns on both cards shown in the drawing. The upper and lower brushes now work together with the group control device under the control of two consecutive cards. The lower brushes 13 assigned to the value punching columns, however, also serve to control the adding units in accordance with the value punching. In the drawing, only the control for the first registration column and; the corresponding adding wheel is shown schematically; however, the same facilities are provided for each column whose numerical values are to be added. Since this device does not belong to the actual essence, the invention, it will only be discussed briefly. The adding unit 16 is driven by the motor 17 of the machine through the intermediary of a claw coupling 18, ig and the gear wheel 2o, from which the drive of the transport rollers ii is also derived. A wedge sits on the adder shaft 16, which takes the coupling element 21 along with the continuous rotation of the shaft 16, but enables the coupling element 21 to be displaced axially. A fork of an angle lever 22, which is controlled by the adder magnet 23, engages in a groove of the coupling element 2i, and when the magnet 23 is excited, the coupling element 21 is brought into engagement with the coupling claw of the counting wheel 24, so that the latter as a result of Rotation of the shaft 16 is rotated further. So if the leftmost column of the lower card punched at 5 passes the brush 13, at the moment when the hole comes under the brush, a current from the power source 25, contact 26, line 27, sliding contact 28, contact roller 15 , Brush 13 of the first column, line 29, magnet 23 flow back to the power source 25. The magnet rotates the Winkelhebe122 clockwise so that the adding wheel 24 is engaged, and at the same time a holding circuit for the magnet 23 is established via the contact 30 , which is closed at this time, by means of the contact plate 31, which until the passage of the zero line of the card under the brushes 13 is maintained; At the last-mentioned point in time, the contact 30 is interrupted by the cam 32 and the clutch 21 is disengaged under the influence of the spring 33. As a result of the existing synchronism between the card transport and the adder shaft 16, the amount 5 corresponding to the perforation in the first column will have been transferred to the adder wheel 24 after the end of the process of the lower card io on the brushes 13. The contact 26 is controlled by a cam in such a way that it is opened every time the brushes come into contact with their associated contact rollers as a result of the space between two successive cards, so that in this case no control pulse can be triggered.

As already mentioned, the card feed and the transport of the cards, as well as the drive for the adder, are derived from the gear wheel 2o, which can be coupled to the motor 17 by the coupling 18, ig. When the main switch arranged in line 36 is inserted, motor 17, which is then connected to power source 25 via lines 36, 36a, is continuously in operation. When the start button 34 of the machine is depressed, a circuit via line 37, contact 35, line 38, clutch magnet 39, line 40, contact 41 and line 42, which is closed at this time, is established by contact 35, which circuit is parallel to the motor on the Power source. The clutch magnet 39 is therefore excited, and by means of the angle lever 43 the clutch ig is shifted along the splined connection on its shaft to the left so that it comes into engagement with the clutch 18, whereby the gear wheel 2o and thus also the transport device for the cards and the adder shaft 16 are driven by the motor 17 starting at the same instant. The clutch magnet 39 produces a holding circuit via the lines 44, 45 by means of the contact plate 46, so that the clutch remains engaged when the button 34 is released again and the contact 35 opens. In Fig. I. For the sake of easier understanding of the mode of operation, the coupling 18, ig is shown in the uncoupled state, although a card conveyance is assumed. It is clear, however, that when the card is being conveyed, the clutch 18, ig driving the card must also be engaged. Shortly before the end of each work cycle, contact 41 is opened by cam 47, so that the circuit of the clutch magnet is interrupted and the same is de-energized if it does not continue to receive current via a circuit bridging contact 4i. This bridging circuit comprises lines 49 and 48 which are connected to the group control contacts 5o connected in series. These group control contacts are controlled in such a way that if the group numbers of two consecutive cards match, all control contacts 5o are closed, so that when contact 41 is opened, a parallel circuit is established via line 49, contacts 50 and line 48 and the clutch remains engaged in this case . However, if the identification perforations of two consecutive cards in one or more columns do not match, one or more of the contacts 50 will remain open, and when the contact 41 is briefly opened, the circle of the coupling magnet 39 is interrupted so that the angle lever 43 is below the Influence of the spring 51, the clutch 18, ig interrupts, whereby the card transport device and in the illustrated example also the adder shaft are stopped. Subsequently, if necessary, the total of all items belonging to this group in the adding wheels can be automatically printed out, and then the machine can start up again to start the accounting of a new card group.

The setting of the group control device according to the present invention to any columns will now be explained in more detail with reference to the schematic representation according to FIG. I. In this representation it is assumed that the group control device consists of four control magnets 5a (labeled a to d ), so that in the maximum case four hole gaps can be monitored. A control contact 5o is assigned to each of these magnets. The electromechanical control of these contacts by the magnets 52 is illustrated in FIG. An angle lever 53 is assigned to each magnet and control contact, which is normally caused by a pawl 54 forming the armature of the magnet 52 in the position shown in this figure. vivid location is kept. When the magnet 52 is excited, the pawl 54 releases the arm 53, and the spring 55 rotates the angle lever 53 counterclockwise about the pivot point 56 against the stop 57, so that the nose 58 closes the contact 50 and keeps it closed until further notice , even if the pawl 54 is pulled back into its starting position by the spring 59 after the magnet 52 is de-energized. The contacts 5o closed as a result of the excitation of their magnets remain closed until shortly before the end of the working cycle; this is also the case when the contact .I1 (Fig. i) is opened, but shortly thereafter the tip of the cam 6o, which rotates once in each working cycle, hits a nose 61 of the angle lever 53 and returns it to its normal position in which his horizontal arm snaps behind the nose of the latch 54. While all the parts described are provided separately for each individual control column, the cam 6o can be designed in a known manner as a cam drum common to all angle levers 53.

The control magnets can be optionally connected to the sensing brushes i2 and 13 by means of two adjusting members 62 and 63. Lines 64 lead from the 15 upper sensing brushes i2 to contacts 65. Lines 66 lead from the lower brushes 13 to contacts 67. The setting element 62 forms an insulation block in which three groups of four each. Contact fingers 68, 69 and 70 (labeled ca to d ) are arranged. The contact fingers 68 slide on the contacts 65, and the contact fingers 70 slide on the contacts 67. The corresponding control magnets 52 are located between the contact fingers 69 and 70, in such a way that the control magnet 52 ″ lies between the contact fingers 69 and 70, and so on The setting member 62 is also equipped with two groups of three contact fingers 71 and 72 each (labeled b to d ). The control contacts 50 with the same letter designation are located between the contact fingers 71 and 72 intended. Within the setting member 62, another setting member 63 is displaceable, the latter being provided with four bridging contacts 73 which, depending on the setting of the member 63, electrically connect or interrupt the contact fingers 68, 69 on the one hand and the contact fingers 71, 72 on the other hand. In Fig. I, the member 63 is set relative to the member 62 such that the contact fingers 68 and 69 of the a, b and c point are connected to one another, while there is no conductive connection between the contact fingers 68, 69 of the d point . The contact fingers 71, 72 of the b- and c-point are open, while the contacts 71, 72 are conductively connected in the _d-point through the first contact .73 of the member 63, so that the control contact Sod is short-circuited. Depending on the setting of the members 62 and 63 with respect to one another, the contact fingers 68, 69 can now be connected in more or fewer places and the control contacts 50 can be short-circuited. Since three columns are to be monitored in the above case, namely the 5th, 6th and 7th registration columns, the contact fingers 68, 69 of the a, b and c positions are connected, whereby the control magnets 52a, 52b and 52, in the group control circuit are switched on while the magnet 52.1 is switched off; At the same time, however, the control contact Sod belonging to this magnet is short-circuited by the leftmost bridging contact 73.

Therefore, when the 5-hole of the hundreds identification column of two cards passes the brushes 1.2 and 13, a current from the power source 25 is passed through the at that time. closed contact 26, line 27, contact roller 15, brush 13 in the fifth column, corresponding line 66, contact 67, contact finger 7o ", control magnet 52a, contact finger 69a, bridging contact 73, contact finger 68", contact 65 of the fifth column, corresponding line 64 , Brush 12, contact roller. 14, grinding brush 74 and flow back to the power source via the closed switch 75 and line 76. The magnet 52 "will thus be excited and close its contact 50a. Similar processes take place when the i-hole of the tens identification column and the 4-hole of the units identification column pass the brushes, so that finally the magnets Soa, 50b , 50, are energized and their associated control contacts 50 have been closed, while the contact Sod is short-circuited in the manner described above It can be seen that if the group perforation does not match in certain columns of two consecutive cards, the brushes 12, z3 do not establish a conductive connection with their contact rollers at the same time, so that the associated magnet 52 is not energized; therefore the corresponding control contacts 5o are not activated either t is closed, and if the contact 41 is opened after the upper card has passed on the upper brushes 12 and the lower card on the lower brush 13, the circuit of the clutch magnet 39 is interrupted and therefore the clutch i9 is disengaged, so that the set-off is interrupted will.

When the adjusting member 63 is pushed into its extreme left position, all three contact finger pairs 7 i, 72 are connected so that the control contacts 50b, 50 and Sod are short-circuited. However, the connection between the contact fingers 68a, 69 ″ is maintained by the rightmost bridging contact 73, so that at least the control magnet 52 is always switched on in the group control circuit the four contact finger pairs 68, 69 lie, in which case all magnets 52 are switched on in the control circuit and none of the contacts 5o is short-circuited.

It is therefore readily apparent that by setting the member 62 relative to the contacts 65, 67 and by the relative setting between the members 62 and 63, one to four arbitrary registration columns on the card can be selected for group control. If it is desired to have the machine operate without group control, it is only necessary to open switch 75, which completely disconnects the upper brushes from the power source.

An embodiment of the adjustment device, which is shown in Fig. I is illustrated schematically, will now be explained in more detail with reference to Figs will.

On a base plate 77 are two insulating strips by angle 78 79 and 8o attached; The contact pieces 65 are pressed into the bar 79, too the upper brushes i2 lead (see also Fig. i), and the contact pieces 67 of the bar 8o are connected to the lower brushes 13. As well as the contact pieces 65 and 67 are also the connecting contacts of the adjusting members to be described pressed into their carrier made of insulation material. The embodiment according to Figures 2 to 6 is for 45 registration columns (corresponding to the usual card size) and set up for a maximum of eight group control columns, in contrast to the schematic Representation according to FIG. I, in which the card comprises only 15 registration columns and the group control facility is only intended for a maximum of four columns.

The insulating strips 79 and 8o are provided with grooves into which guide rails 8i and 82 (FIGS. 4 and 5) are pressed, and the adjusting member 62 is displaceable in the longitudinal direction in these guide rails. The setting member 62 (Fig. 3) is equipped with eight contact fingers 68 which are embedded in the setting member and cooperate with the contacts 65 on the one hand and the bridging contacts 73 of the second setting member 63 on the other hand. Eight contacts 68 and eight contacts 73 are also provided, corresponding to a number of eight monitoring magnets. The setting member 62 also carries contact fingers 69, # which are connected to the contact fingers 70 with the interposition of the control magnets (see FIG. I), the latter cooperating with the contact pieces 67 leading to the lower brushes. The position of the short-circuiting contacts 71, 72 for the control contacts 5o (FIG. I) can be seen from FIGS. 4 and 5. The contacts 71 and 72, which are connected at their lower end to the mentioned control contacts, are embedded in the setting member 62 in the manner shown in the drawing and can be short-circuited by the bridging contacts 73 of the setting member 63. The adjusting member 62 has a groove 83 within which the adjusting member 63 is displaceable. Analogous to the scheme according to FIG the corresponding seven control contacts 5o are short-circuited, while only the contacts 68, 69 of a single point are connected by a bridging contact 73, so that the control magnet in question can be effective with its control contact. As can be seen from FIGS. 3 and 4, the bridging contacts 73 are pressed into the slide 63 in such a way that their outer surface forms a smooth surface with the slide 63, so that the slide can easily be attached to the contacts 68, 69, 71 and 72 slides along. So that the two setting members 62, 63 cannot be pulled apart further than corresponds to the maximum number of group control elements, ie that no more than eight registration columns can be set, a limitation device shown in FIGS. 4 and 6 is provided. In the adjusting member 63, a U-shaped rail 84 is pressed, which ends at an angle 85; a pin 86 is pressed into the lower part of the adjusting member 62 and limits the movement of the member 63 to the right (FIG. 6). When the member 63 is pulled out of the adjusting member 62 so far that the angle 85 abuts the pin 86, all eight contacts 68 and 69 (FIG. 3) are connected by the eight bridging contacts 73, and all seven short-circuiting contacts 71, 72 are open, so that the maximum number of registration columns permitted for group control is activated. Depending on the setting - of the members 62, 63 to one another, one to eight columns of the 45 registration columns of the card can be placed under group control.

To feed the lines coming from the upper and lower brushes to the contacts 65 and 67, two slots 87 (FIGS. 3 to 5) are provided in the base plate 77, and another slot 88 is used to feed a bundle of wires which is attached to the contacts 69, 70 on the one hand and to the contacts 71, 72 on the other hand. This bundle of lines leads to the control magnets 52 (FIG. I) and to the control contacts 50 and is displaced simultaneously with the adjusting slide 62 in the slot 88 of the base plate. In the embodiment shown, it is assumed that the entire housing is placed on the machine at a suitable location and that the lines are fed from the machine through the base plate 77.

At the left end of the adjusting member 62 (Figs. 3 and 6) is a Plate 89 and attached to the right end of the adjusting member 63 a plate 9o. A link 9i is placed on each of these plates at the upper end, which ends in a square 92 on which a handle 93 or 94 is seated. The handle 93 is with a pointer 95 (Fig. 2) and the handle 94 connected to a pointer 96, which with upward and downward flaps 97 in a slot 98 of the housing cover 99 are performed. The slot 98 is provided with notches ioo, in the Square edges 9a attached springs ioi intervene to adjust the pointer and thus to secure the adjusting members in a precise position. On the case 99 is attached a scale corresponding to the device of the present embodiment on 45 columns with i to 45 and over which the pointers 95 and 96 to play. In the drawings, however, an intermediate piece has been cut out for reasons of space, without that the clarity suffers. From the illustration according to Figure 2 is can be seen that the fifth through the ninth column of the cards below Group control stand. As can be seen from a consideration of FIG. 3, are also actually the contacts 65 and 67 of the fifth up to and including the ninth connection point connected to the control magnets, while the remaining three contacts 68 and 69 are interrupted; corresponding to the use of five control posts the short-circuiting contacts 71, 72 assigned to these control points free while the remaining three contact pairs 74 72 through contacts 73 are short-circuited.

The two pointers 95 and 96 are in 'different planes and cover exactly when the two adjusting members 62 and 63 are pushed together, in in which case only one registration column is monitored. If a range of columns goes to Group control is to be selected, the pointers 95 and 96 are the handles 94 and 93 are set to the desired scale range, whereby the group control device by means of the slide 62 and 63 completely automatically is turned on to the same area. If only the first column is checked is to be, the handle 93 is pushed all the way to the left, so that the pointer 95 on Scale mark i is set, and the setting member 63 is completely in the setting member 62 pushed in so that the pointers 95 and 96 coincide. If only the column 45 is to be checked, both adjusting members 62 and 63 are again whole pushed together; the handle 94 is then at its far right end, and the two overlapping pointers 95, 96 point to the last registration plate. if the machine is to work without any group control, switch 75 (Fig. i and 2) in its right position, which is designated in Fig. 2 with O, rotated, while he stands in the illustrated G position during group control.

As mentioned at the outset, the invention is intended to relate to a mechanical group control device are applied, the contact connections by the following equivalent elements Replaced: A set of contacts 65 or 67 would be spring-loaded pins each contact would correspond to that of mechanical tabulating machines usual principle of the simultaneous sensing of all hole positions in a column replace with a series of ten feeler pens. The memory device mentioned at the beginning for group control -which the former is trained in a manner known per se can be - owns for each control element, i. H. for each column, ten control pins, which are monitored by the sensing pins, the control pin rows to any Sensing pin rows are adjustable. The connection between a row of sensing pins and a row of control pins, however, is not immediate, but occurs under Interposition of a number of coupling pins. The different rows of Coupling pins sit on a carrier, the slide 63 of the above Embodiment corresponds and by its relative setting between the Sensing pin rows of the punch card and the control pin rows of the group control device through the coupling pin rows a connection between more or less sensing and Control pin rows is produced, while the unneeded control pin rows are exposed and do not establish any connection. The invention can of course also It can also be used for any other type of mechanical group control system find, e.g. B. also in the form that it is used in connection with facilities in which all or some of the aforementioned types of rows of pins are in each Column through a. only common element are replaced.
