Description

Punch card copier. The present invention relates to improvements in card punching machines. In the Tabelliermaschinentechnik it is customary to provide cards with holes representing various types of 'statistics. These cards are used to classify the statistical material presented by the cards through processing in sorting and tabulating machines. During this statistical work it is sometimes necessary to copy relatively large groups of maps.

Such copying of punch cards has hitherto been effected by hand punching and was consequently time consuming, costly and difficult. In addition, there are such Card copies, the production of which depends on the accuracy of the worker, do not absolutely flawless.

When producing such duplicate cards, it is sometimes desirable part of the statistical information that is on the original card, to leave out; in other cases it is desirable to use the hole symbols to be transmitted to be arranged differently on the card copy and on other card fields and to be accommodated in other graters than on the 'perforated card originals.

It is also desirable to take precautions against certain holes or groups of holes, which are to be repeated on the card copies, automatically get to the punching and that such recurring card holes in any card fields or groups are accommodated (n can.

The present invention now has a machine as an object in which Groups of perforated cards and also card blanks can be inserted and when it is put into operation, it automatically softens the perforated Cards as well as the blank cards conveyed through the machine and clal-ei the perforations in the perforated cards and a corresponding perforation in causes the card blanks.

At the same time, the machine is set up in such a way that reproduction is more specific Holes of the perforated sample cards on the card copies can be suppressed and that a regrouping of those to be transferred from the pattern punch cards to the blanks Holes can be made in the manner that the holes on the card copies in squares or rows other than those on the sample cards.

The new card punching machine also allows you to work automatically on the card copies make recurring perforations in specific, designated fields and the transfer of certain perforations occurring on the perforated sample cards to prevent the card from being copied as desired while taking further punch holes Using a setting device of the machine according to Wa hl can be generated.

A preferred embodiment of a machine according to the invention is shown on the drawings.

In the new machine, storage and disposal containers are initially provided for both punched cards and unpunched cards. The machine secondly has ESTABLISHMENT 'gene to the perforated and non-perforated card from their Vorratsbehältcrn in the laying-Keeps to convey (-r. Further, ge (-ignete Abigreiforgane are provided to the holes in the already perforated cards tap off and to drive punches , which act on the unperforated cards, züi monitor.

In addition to the above devices, devices are provided such as B. a contact plug plate to regroup the perforated by the Carry out the card on the 5 card duplicate holes to be transferred.

The machine is also provided with facilities for the transmission of holes that are located in part of a series of the hole -], delicate, to the to prevent new card to be punched and, if desired, in the same row of the To make a new hole in the duplicate card.

The machine is also provided with facilities for the transmission all holes (r of a certain field of the punch card original, -ina! s on the duplicate to prevent and, if desired, a new hole or on the duplicate cards Punch a group of holes that represent a number that appears with each new one Card returns.

According to the illustration of the drawing, the new punch machine has the usual frame plates, in which the main drive shaft is stored, which is in any suitable manner, e.g. B. by a motor not visible on the drawing, is driven. The gear shown in Fig. I is capable of going back and forth walking crank.greiferarm ii and upper transport rollers 12 and lower transport rollers 13 and the laying roller 14 (Fig. 2). It may be noticed. that the Transport rollers, the gripper mechanism and the deposit mechanism in the machine are available twice, namely a set for the punched cards or the original cards and a second set for the unperforated cards or card blanks. These parts work in harmony with each other.

According to Fig. 3 , the original cards are removed from the storage container 15 by the gripper and fed to the transport rollers 12, from which they pass through a further mechanism to the transport rollers 13, which in turn feed them to the deposit mechanism, through which they reach the deposit container 16. FIG. 2 shows a similar arrangement for the type blanks in order to remove them from their storage container 17 and to convey them in the perforated state into their storage container 18.

Both the original cards and the cards to be punched are advanced step by step on the way from the upper transport rollers 12 to the lower transport rollers 13 so that the punching and new cards can be made while they are at rest. The perforated cards can be picked up while the cards are in motion, and this picking up of the cards monitors the work of the punch, which takes place at a later point in time during the card movement.

As can be seen from Fig. 3 , the shaft io carries a cam groove disk ig which controls a lever 2o which engages a vertically displaceable toothed rack 21 which is in tooth engagement with a drive 22 which is on a ## l'elle 2V " sitting, transmits the drive wheels 23, which engage in vertical toothed racks 24. ig effected while a suitable design causes the stufenförrnige limiting groove a gradual downward movement of the Zabnstangen 24 a specific distance section of the Nutbegrenzung a rapid return of the racks. each rack 24 is suitably for vertical movement in the machine frame, guided and supports a rearwardly projecting part which carries a gripping mechanism which is able to receive and grasp the cards.

The gripping mechanism consists of a block 25 (Fig. 7 and 1: 0) and spring- loaded gripper arms 26 to which a locking arm 27 is assigned, which is under the influence of a stepped pawl 28 . Fig. 7 shows the gripping device in its working position, where it presses the card against the block?, 5. Each gripping mechanism has a protruding approach with which it can grip under the edge of the registration card in order to determine it in the correct position on the gripper slide. The release of the card and the opening of the gripping organs is caused by a cam 29, t, which is able to grasp a pin 30 , which sits on the locking arm 27 and comes into effect when the gripper slide has reached its extreme low position (Fig. 10) . The gripper 26 to go to its release in the lowest position with the carriage in the height outside the lane on which the card moves, as shown in Fig. Io is visible because it into diesel, it will be held by the catch 28 situation . Immediately before the gripper carriage reaches its extreme upper position and immediately before a new card is gripped, the grippers are triggered by a fixed pin 31 which is seated on the machine frame. This pin presses the rear end of the pawl 28 down so that the front end of the pawl releases the gripper arms 26.

So that the cards are gripped in the correct position by the gripping mechanism and also transferred to the lower transport rollers 13 in the correct position, upper and lower adjusting fingers 32, 33 (Fig. 2, 3) are provided, which by means of cams 34, 35 by means of cams 36 , 37 on the shaft 38 can be controlled.

This shaft is set in rotation by the gear shown in Fig. I. The arrangement of the linkage is such that the alignment fingers 32, 33 are raised over the rear edge of the two cards and then lowered so that they come into contact with the card edges and bring the cards into the proper position. During the upward movement of the adjusting fingers, which occurs while the gradual downward movement of the card carriage is taking place, the fingers are pulled backwards from the path of movement of the downwardly moved cards. The adjusting fingers are then lifted up over the upper edge of the next pair of cards and pushed forward again so that they are able to give the cards the correct position.

Across the part of the machine through which the punched cards are transported, a bar 4o is arranged, which carries contact brushes 41, the cards with contact blocks sent through the holes in the machine 42 interact. This contact brush arrangement is that of tabulating machines generally common and does not require any further description.

The contact blocks 42 are connected to selector magnets 45 by a contact plug plate 43 (Figs. 4 and 13) which will be described later. Each voter magnet can control a special punch, as will now be described. The punch 46 (Fig. 2, 6, 7), one of which each is provided for each row of holes of the produced card are mounted in a frame 4-7, and 'can by means of a common drive beam to pass struck by the card 48. The drive bar 48 is slidably mounted in the machine frame and is swung back and forth by a cam 49 which acts on pin 50 on the bar 49. The cam 49 sits firmly on a shaft 51, which is set in rotation by the shaft io by means of a drive 52 (see FIG. 2).

In order to activate one or more punches depending on the excitation of the selector magnets 45, coupling members 53 are provided, which usually assume the position shown in FIG. When a certain magnet 45 is excited, its armature is attracted, with the result that a wire 55 is pulled to the right, causing a corresponding oscillation of the pawl 56 counter to the direction of movement of the clockwise. This releases a T-shaped lever 57 from the pawl 56 so that a spring 58 can rotate this lever, engaging the coupler 53 in the gap between the punch 46 and punch drive shaft 48. When the bar 48 is then advanced against the card to be punched, the punch 46, the associated coupler 53 of which is engaged in the gap between the bar 48 and the punch, is advanced against the card to be punched and perforates it. The perforation occurs while the card is loading alone. In order to retract the punch, hinged fingers 6o are provided which grip behind the punch heads. These fingers 6o receive their drive from a rail 61 which is in direct connection with the punch drive bar 48 so that it is moved by the latter (Fig. 7). In order to return the T-shaped lever 5-7 to the starting position and to lock it by the pawls 56 and to lift the coupler 53 out of the gap between the beams 48 and the punch 46, an angle lever 63 is provided which is rotatable on the shaft 64 sits and carries a cross bar 65 which engages under the T-shaped lever 57. The angle lever 63 is swung out by a pin 66 on a disk 67 , which sits on the camshaft 51: at the appropriate point in time of each operation. In this way, the various parts are brought into the preparation position for the next perforation. A suitable return spring 68 serves to lower the crossbar 65 * seated on the angle lever 63 again after the return of the parts has ended.

From the circuit diagram of Fig. 13 it can be seen that two main lines 70, 71 are provided for the power supply. The beam 40 is connected to the line 7o. The various contacts 42, only three of which are indicated in the drawing, are connected by suitable wires 72 to plug holes 73 on the contact plug plate 43. The roller magnets 45 are connected to the various contact plug holes 74 of the plug plate. The current return line for the selector magnets contains a wire 75 which leads to the cam contacts 76, 76 a and from these through a wire 77 to the main conductor 71. The purpose of the cam contacts 76, 7611 is to shut off the power to the voter magnets 45 at such time as there are cards under the contact brushes 41 and to cut it off when they are not, e.g. B. while the contact brushes are in the space between two consecutive cards. These cam contacts are the ones. similar to those commonly used in tabulating machines for the same purpose.

The purpose of the plug holes 73, 74 is to enable a cross connection to be made, whereby an electrical connection can be made between any rows on the punched card associated brush contacts and any selector magnets 45, so that perforations on the card copies under the control of the brush contacts can be made the same locations as can be created on the perforated sample cards as well as at a different location.

The cam contacts 76, 76a are provided on the main drive shaft io. This shaft also carries a bush 79 on which two groups of slotted disks sit. One group comprises 7 disks, which are designated 8o, and the other group comprises a single disk 81 as shown in the drawing (Figs. 4 and 6). A disc 82 is provided with incisions on its circumference, into which a pawl 83 can be inserted, which is fixedly arranged on a bush 84 which is slidably seated on a shaft 85. A fork 86 is also firmly seated on the bushing 84 and engages in a coupling part 87 which is non-rotatable but slidably seated on the shaft. On the fork 86 there is a pincer lever 88 which can be inserted into each of the three recesses 89, go, gi, which are provided in a suitably arranged fixed plate 92 (FIG. 4). When the parts are in the position shown in Fig. 4, the clutch 87 is disengaged and the pawl 83 engages the recess on the periphery of the disc 82 so that the disc 82, the bushing 79 and the slotted discs So and 81 against Rotation are secured. When the caliper lever 88 eLus of the recess 89 is lifted and the bushing 84 is moved so that the caliper lever can be inserted into the recess go, then the coupling 87 is also still out of engagement with the disc 82, but the pawl 83 is from the disc 82 uncoupled. With the parts in this position, the indicator disc 82 can be rotated by hand into any desired position so that pegs 93 can be inserted into the slots in the discs 80 or 81. These pins act as cams which bring about the opening or closing of contacts associated with each disk So or 81. The contacts cr4 are those which can be closed by the pegs 93 of the slotted disks So, while the individual contact 95 can be opened by a peg 93 in a slot of the disk 8r. The position of the slots in the discs is such that the contacts 94 or 95 are opened or closed in those moments in which holes in the perforated sample card under the contact brushes 41: pass. In order to bring about such contact monitoring during normal operation of the machine, the caliper lever 88 is inserted into the recess gi, as a result of which the clutch disc 87 comes into engagement with the disc 82. In this coupling position, the disks So and 81 rotate together with the shaft: [o.

The purpose of the contacts 95, 94 can best be understood from the circuit diagram of FIG. It will be noted that contacts 94, only a pair of which can be seen in FIG. 13 , lie in a conductor 96 which extends between the main conductor 70 and a group of plug holes 97 on the plug board 43. These plug holes can optionally be conductively connected to individual plug holes 74, which in turn are connected to the selector magnets 45.

By inserting pegs 93 into the recesses of the disks, with a suitable connection between plug holes 97 and 74, each time the peg 93 passes the contact 94, excitation of a selector magnet 45 and thus a perforation can be brought about. This makes it possible to provide recurring perforations in the duplicate cards, the position of which depends on which of the slots on the circumference of the discs So a pin 93 is inserted. It should be noted that the mortises 97 can be connected to any mortises 74, which makes it possible to provide the holes repeated in the card copies at any point on the new cards.

Regarding the registration card shown in Fig. 9 , it should be noted that a row of registration marks is shown at the far right end of the same, in which there are special identifying marks. In individual cases it may be desirable to leave out a certain hole in the original card on the duplicate. In other cases it is desirable that not only one hole in the original card is omitted from the copy, but that a different hole appears on the copy, depending on the setting of the machine. The contacts 95 are now used to monitor these rows of cards. Of course, other rows of cards can also be monitored in this way, in which case additional discs 81 would have to be provided. Contacts 95 are usually closed but can be opened by pins 93 . The contacts 95 lie in a power line ioi which starts from the cactus block 42a, which is furthest to the right in the row of contact blocks, and ful-lit to the plug yoke 73a. It is noted that irrespective of whether the circuit line section ioi containing is closed by the associated contact brush or the circuit is not in any case wholly ineffective when the contacts are open 95 while the card circuit is produced so that in In this case, the associated voter magnet 45 is not excited. This enables the new card to be prevented from being punched regardless of whether there is a hole in the original card. One or more pegs 93 are inserted into the discs 81, depending on the number of holes which are not to appear in the duplicate card. If. not only wishes not to leave a hole in the card stock into the card duplicate appear, but also to produce a non-existent on the original card perforation, then one can for this purpose one of the pins 93 on a slice 8o in connection with the controlled thereby contact 94 use. A plug 93 is inserted into one of the slots in a disk 8o, and the associated circuit section 96, which leads to one of the plug holes 97 , is plugged with an auxiliary plug hole io2 in the circuit section ioia, which leads to the selector magnet 45. With this adjustment of the parts, the selector magnet 45 does not receive a current pulse the moment a hole in row 100 passes under the brush, but it is excited the moment the particular contact 94 is closed. In this way it is possible, when copying a punched card original, to omit a hole in the original on the copy and to replace it with another hole.
