Description

The present invention relates to machines for perforation of statistical cards, having a dial mechanism for the spherical movement of the carriage in one direction during the action of the dial mechanism. In order to annul the wrong set of punches and return the carriage back, the proposed machine is equipped with a device for activating which from an continuously rotating shaft an electromagnetic device is provided with a control mechanism designed to regulate the movement of the carriage by only one row of punches with each press back key.

In FIG. 1 shows the front view of the proposed machine with some parts removed for greater clarity; FIG. 2 is a side view with a partial cut; FIG. 3 and 4 mechanism, cancellation set, in separate stages of work; FIG. 5-control mechanism in the off position; FIG. 6, 7

and the 8-position of the control mechanism in various stages of work; FIG. 9 is a diagram of an electromagnetic device; FIG. 10-part reversing mechanism.

The rails 23 mounted on the main frame 20 (Fig. 1) are moved on rollers 22 by a carriage 21 carrying a row of push pins 24 (Fig. 2) acting from keys (not shown in the drawing) to composing rods 25 which are locked in its lower position, the corresponding latches 26, which are moved into position of the springs 27. Each extension rod 25 contacts the lower end with a pin 28 located directly below it, which is provided with a spring, which supports the stud 28 and the corresponding extension rod 25 in the upper polo life. The number of rows of composing rods 25 corresponds to the number of columns to be perforated in the card, and the carriage 21 is provided with one row of push pins 24, which are alternately mounted over successive rows of composing rods 25 by movement of the carriage 21, the punches 29 supported by the bar 32 enter movable frame 30, with each pin 28 corresponds to a separate piercer 29 located below it on the same vertical. When the dowels 28 are dialed so as to represent the desired amount or quantity, and the card is inserted into the slot 31 of the frame 30, the latter is lifted upwards, taking with it all the punches 29, the ends of which rest on the card. Those of the punches 29, which abut against the typed dowels 28, are kept by them from further lifting and the cards are perforated. The bar 32, when lifting the frame 30, serves to guide the punches 29 and, when the frame 30 moves downward, to remove the punches 29 from the card. The entire mechanism described is known and forms part of the well-known punching mechanism of the drive perforator machine.

It often happens that when dialing the machine, the operator presses the wrong pin 25 and the corresponding pin 28. At the same time, the carriage automatically goes to the next column of pins. The invention aims to return the carriage reliably and quickly to the row or to the column of pins where the error occurred, and to allow a new set to be made in that row by destroying or canceling the wrong set of pins.

The carriage 21 is constantly attracted by the tape 33 and the spring 34 to the right end (Fig. 1) of the machine. This movement of the carriage to the right is controlled by a ratchet 35 and dogs 36, Zba. A lever 37 is pivotally attached to the frame of the carriage 21 with a shoulder 38 provided with a upwardly directed protrusion, the extended upper edge of which is located below the lower edge of the bar 39 attached to the fixed part of the machine. The downward-facing arm of the lever 37 is pivotally connected to the earring 40, the lower end of which is articulated with the swinging body 42 with a pin 41. The upper end of the earring 43, the lower end of the connected

with a lever arm 44, fortified rotationally on the frame of the carriage 21 and carrying a conical roller 45 on the other shoulder, which is located above the tensioned part 46 of the release lever 47 (Figures 2, 3 and 4). There are several such release levers 47, one for each latch bar 26; A dog 48 returning the carriage is planted on the same axis with the lever 37 (Fig. 1), the free end of which ends in a tooth (Figs. 1, 3 and 4). The dog 48 is kept in an inoperative position in contact with the lower edge of the stationary bar 39 by a spring, one end of which is attached to the dog 48, and the other end is attached to a pin protruding from the frame part of the carriage 21. On the fixed bar 39, the rod 50 is movably fixed with pins 51, provided at the ends of the slots 52, the left (Figs. 1, 3 and 4) of which has a slope, and the right is horizontal. The teeth 49 of the lower edge of the rail 50 are directed to the left (Figs. 3 and 4), and the spring of 53 tons does not have the rail 50 to the right, so that its teeth are raised and disengaged from the pawl 48 and the shoulder 38, which is achieved by the joint action of the pin 51 and the inclined of the slit 52. The rail 50 is connected by an earring 54 to the upper arm of the angle lever 55, swinging on the pin 56 and having on the other shoulder an arc slit 57 (Fig. 1, 3, 4 and 10), which includes a pin 58 attached to the fixed part cars . On the pin 56, the lever 59 also swings, equipped with an arc slot 57a (FIG. 10), coinciding with the arc slot 57 of the corner lever 55, the upper arm of which is connected to the upper protruding part of the lever 59 by the spring 60, and the pin 61 on the last one serves a stop for the lever 55, so that the lever 59 and the angular lever 55 normally move as one piece. A flexible connection is provided here, so that if something prevents the carriage from making a reverse movement, and the return mechanism is in operation, then the lever 59 receives a separate movement, and the mechanism is not damaged. Spring 62 tends to hold portions 55 and 59 in their upper position defined by pin 58 and slits 57

: and 57a, the free end of the rocker arm 59 is connected by a pull 63 with a pin 64 to the case of the electromagnet 65, freely seated on a continuously rotating shaft 66 of the machine, on which a disk 67 is fixed next to the electromagnet 65. Fig. 9) the switch is closed at point 69, and the current from the network 70 passes through wires 71 and 72 to the electromagnet 73, then through the wire 74 back to the network 75. The anchor 76 is fixed on the plate 77 (Fig. 5), and the free its end is provided with a set screw 78 in contact with its lower end with the end of the left end (FIG. 5) the shoulder of the lock lever 79, the right shoulder of which for this purpose is pulled down by the spring 80. On the stationary part of the machine the lever 81 is rotated, the lower end of which is provided with a finger 82 located under the right shoulder of the lock lever 79 and abutting under the action of the spring 84 into the protrusion 83. On the common axis with a locking lever 79, an auxiliary locking arm 85, which is attracted to it by a spring 86, is seated, the protruding part 87 of which is located slightly to the left of the protrusion 83 (Fig. five). The horizontal arm 88 of the lever 81 is provided at the end with insulation 89 located under the contacts 90, 91 (Fig. 5 and 9), which close the current coming from the network 70 (Fig. 9) through the wire 92 to the electromagnet 65 and from there along the wire 93 , through contacts 90, 91 and through wire 94 back to the network 75. When pressing the reverse button 68 (FIG. 9) closes the current in circuit 70, 71, 69, 72, 73, 74 and 75 of electromagnet 73, the latter attracts measles 76 (FIG. 5), and vnnt 78 rotates the locking lever 79 so that the protrusion 83 goes out of engagement with the finger 82, which moves from the position of the consonant . 5 and 6 to the position according to FIG. 7. The horizontal arm of the lever 81 is kept from further movement, resting against the contacts 90, 91, thereby closing the current in the circuit 70, 92, 65, 93, 91, 90, 94 and 75 (Fig.9) of the electromagnet 65, which captures The disk 67 (Fig. 1) and with it rotates, attracting downwards to the rim 63 (Figs. 1, 3 and 4) together with the rocking lever 59 and the angular lever 55. As a result

The earring 54 deflects to the left (Fig. 3), which carries the rail 50, which, by the action of the pins 51 on the inclined parts of the slots 52, presses downwards before the teeth 49 catch with the pawl 48. Further, (Fig. 4) the movement of the rail 50, the pins 51 enter t in the horizontal part of the slots 52, and the carriage 21 is carried away to the left a little more than the column distance, which ensures proper engagement of the releasing dog and the ratchet. At the same time, the teeth 49 of the slats 50 push the protrusion of the shoulder 38 of the lever 37, as a result of which the earrings 40 and 43 are raised, and the swinging lever 44 rotates on its axis so that when moving the carriage 21 to the left, the roller 45 acts on the inclined surfaces 46 releasing levers 47, which move the respective latches 26, thereby releasing the pushed-in pin rods 25 and the pins 28. When the rocking lever 59 is pulled downwards with the thrust 63 and after movement is sufficient to reverse the movement of the carriage 21 and cancel the kit In this case, the lower edge of the lever 59 (Fig. 5) presses the insulation 89 and, by opening these contacts 90, 91, interrupts the current in the circuit of the electromagnet 65 (Fig. 9), which is released from the disk 67 and together with 63 59, 55, 54 and 50 returns to their original position under the action of springs 53 and 62. The lever 81 deflects and pushes the finger 82 over the protrusion 87 of the auxiliary locking lever 85. When the reverse button 68 is canceled, the electromagnet 73 opens and the spring 80 returns the locking lever 79 and the parts in contact with it to their original position according to As shown in FIG. 6
