Description

The invention relates to a machine for printing addresses, or the like, of destination, with the connection of the printing subtussles, v j} {QiUBQ4JUTjCfi to the installation and the head pech11yu || ; | G6. fttisa. When supplying a tajaii machine with the well-known prispresco, dd automatic, gteriodi 1 (SCOG9 before moving the tape, jailllfOflt. when, due to the shutdown of the cushion, the template in the printing position does not produce a print at all. The present invention aims at completely eliminating this disadvantage. It consists in the fact that the boom system that actuates the paper tape mechanism, depending on the switching and coupling device, connects to the positioning roller in the head of the Njuti ro furnace by the setting roller of the press of the cushion that when turning this setting roller from the printing position to the position for passing the paper feed mechanism automatically turns off, or this drive is turned on only if an imprint has indeed been made from a template that is in the working position. This form of the invention is particularly recommended, for which the connecting rod wire, Hp ("cBpcjqi | m"; for feeding the paper strip, splits into two telescopically displaced one relative to another part, of which the one that is fixed to the printing arm may have a tubular shape. K This tubular part is reinforced by an interlocking device that is turned on and off by a relocation rod system, controlled either directly by the mounting roller, in the head of the printing arm, or by a mechanism that causes . The action of the roller in dependence on, in a position to turn the roller, both sides of the driving rod are coupled either to each other fixedly, or can be moved relative to one another Coupling device consists essentially of a rotationally strengthened 2. -

captive to the tubular part of the driving rod of the engaging lever, provided with a hooked end and a ratchet lever, also supported rotationally to the same tubular part. The coupling lever consists of two parts swinging about a common axis, of which the part intended for coupling with the other part of the drive rod and provided with a hook-shaped end for this is done more desirable than the other part, and a spring is connected between both parts. The latter comes into effect only when the ratchet lever belonging to the adjustable rods system prevents the rear part of the coupling lever upwards near the common axis and pushes the hooked front end of the coupling lever into the notch of the rod-like part of the driving rod when this notch and hooked end of the coupling lever are against each other.

Since the spring included in the coupling lever causes the coupling lever to jump into the coupling position extremely quickly, the coupling of both parts of the driving rod of the belt feeding mechanism occurs even if the switching system of the shifters is rearranged after the printing lever is lowered , as is the case in the address printing machine with the printing pad turned off, in which the setting roller rotates automatically under the action of the printing patterns during Vision to the place of printing.

FIG. 1-15 show two exemplary embodiments of an address printing machine. FIG. 1 shows a cross-section of the machine with the printing pad turned off, at the moment following the shutdown; in fig. 1a is a detail of FIG. one; in fig. 2 - top view from above; in fig. 3 shows the coupling device in the same position as in FIG. 1, but on a larger scale; in fig. 4 is a top view of FIG. 3; in fig. 5 and 6 are different positions of the parts of the coupling than in FIG. 3; in fig. 7-section of the coupling with the corresponding FIG. 6 arrangement of its parts.

on a larger scale; in fig. 8, 9, and 10 are transverse sections along lines m VIII - VIII, IX-IX, and X-X of FIG. 7; in fig. 11 is a cross-sectional view of an address printing machine with an automatic transmission device and a device constituting the subject matter of the present invention, with the printing pad turned off and the printing lever down; in fig. 12 - the same view when the cushion is on and the lever is lowered; FIG. 13-shows the arrangement of the parts of the maschine after raising the printing lever in the case when the preceding lowering thereof, respectively, FIG. 11, the pattern imprint was not received; in fig. The 14-position of the parts when the printing lever is raised after receiving a print from the template, respectively, in FIG. 12; in fig. 15 - a detail of the device. In both of the illustrated forms of implementation, the machine has a table with a guide b, for templates c from which prints are supposed to be taken and which move along this guide b, one after the other, passage through the machine. A printing arm d is rotated on the table, and in its head g there is also an installation roller / printing pad /, which is constantly pressed against it by the action of spring 16. The installation roller / has notches 15 and is equipped with a handle 18, so that depending on one or another rotation of the roller I in the head g, the pad /, more or less significantly protrudes from said head, and the print with the template B in the working position occurs only if the pad U is moved out of the head g of the print present the lever by a certain amount. FIG. Figure 1 shows such a position of the roller (and cushion), in which its rubber pad does not reach the paper on template c while lowering the lever d, so that in this case the template passes through the machine without giving a print, i.e. it passes. A device for periodically feeding paper tape h in the direction transverse to the path of the patterns C consists of two, connected to the table and side beds g and L between which the paper guide film or carriage 1 runs. The bed g is provided with a longitudinal slot for placement ratchet ratchet rail. The latter moves in the said groove back and forth under the action of the toothed sector n and acts together with the dog on the bar with, so that when the rail moves in the direction of the arrow, the dog it and the guide rail also move in the same direction. To reinforce the paper tape L, the carriage i is provided with a clip q. The toothed sector and is actuated by the help of a rotary shatun fortified to the table. By the latter, at any distance from the swing point, a clamp can be fixed, to which the shtanga is hinged. The front end of the latter goes in a tubular bar, m, which is pivotally fixed to the clip V, which is similar to the clip s, and can be fixed at any height on the foot and attached to the printing lever d. As long as the parts and and / are connected to each other tightly (as will be described below), each time the printing lever d is raised, the toothed sector n rotates in the direction of the arrow and, and the toothed rail moves in the direction of the arrow /, and therefore, the paper feed is fed in the direction of the same arrow p. When the lever is subsequently lowered, the toothed sector rotates back to its previous position, dragging along the rail W, the teeth of which slides under the ratchet, thus, so that the carriage retains the position to which it was brought before. Depending on the installation of the clamps g and s on the leg and on the connecting rod g, the tape h with each stroke of the lever d moves to a greater or smaller length. In the embodiment shown in FIG. 1 and 2 of the implementation form for printing the addresses to the installation roller / reinforced bar Y (FIG. 15), with coupling g, equipped with a through hole through which the end 20 of the rod 21 bent at a right angle passes, which can be a help of the clamping screw We fix in the coupling z in various positions. The rod 21 is connected to the tubular part and the driving rod by means of a ratchet lever 27, rotationally at point 28 fixed to said tubular part and. The upper end of the lever 27 is hingedly connected to the coupling 2c, which is seated on the rod 21 on which it can be fixed in the desired position by means of a clamping bolt 50 (figure 8), which is under the action of a spring. However, with sufficient force, it is possible to move the sleeve 26 along the rod 21, despite the resistance of the clamping bolt 50, to set it to the desired position. The ratchet lever 27 has the shape of a fork, the parts of which are connected at the lower end by a cross-beam .9. The coupling arm, rotatably about the axis 51, consisting of a heavier front hooked part 62 and a lighter rear part 55, is strengthened to the tubular part. A coil spring 54 is placed between the two parts 52 and 53 (Fig. 7). The bar t has a notch 33 in the proper place and is kept from rotating relative to the tubular part and inside the latter by a pin 55, which, at the same time, limits the retraction of the parts / and in such a way as to give them a position more extended than shown in FIG. 7, is impossible (at which position the capped end 32 of the lever 52 can jump into the notch 33 of the rod). The operation of the device shown in FIG. 1 and 2 and 1a, is as follows. With the position of the parts shown in FIG. 1, i.e., with the printing pad turned off /, while immediately following the shutdown, the coupling lever 52-53, whose front end is 52 tons more than the rear end 55, assumes the position shown in FIG. 1 and 3, in which its hook 32 is outside the notch 55 tons g t. However, due to the fact that the mounting roller / is disengaged, the ratchet lever 27 comes to the position shown in FIG. 1 and 3, in which its crossmember 31 is placed in the recess 5Q in the rear part 55

 4 hitch lever, however, are not in contact with this part. If with this arrangement of parts, the printing lever of will follow, with the pillow off /, then the pin 55 of part m sweat is not behind the rod / in the direction of arrow 57, without any changes, however, in the relative position of the rod t and the lever 5S-55. The toothed rack is moved, in this case, by the toothed sector and, to the right, in the direction of the arrow 5S, at which movement the fixture i-, actually producing the feeding of the paper tape, remains in place. With the subsequent raising of the printing lever d, the rack bar t still does not get carried away with the reverse arrow 58, but the tubular part also moves along the rod t, as can be seen in FIG. 1 a. If, however, with the position of the parts shown in FIG. 1 and 1 a, turn the handle 18 in the direction of the arrow 5d, and at the same time bring the setting roller /, together with the printing pad, to the working position, then the rod 21 moves in the direction of the arrow 60, as a result of which the ratchet lever 27 turns relative to the tubular part w to the position shown in FIG. 5, 6 and 7. At the same time, the cross member 31 of the lever 27 abuts against the rear, which has a special shape, the end 55 of the lever 55, and thus makes it impossible for the latter to pivot about the axis Y upwards. When the printing lever d is lowered, then the forward movement of the rack t in the direction of arrow 58 occurs, or, if the rack t already occupies the position shown in FIG. 1a, the displacement of the tubular part on the rod / from the position shown in FIG. 5, in the position shown in FIG. 6. By fixing the lever 55, the spring 54 gets a constant desire to press the hook 32 of the lever 52 to the rod / and insert it into the notch 55 and the latter as soon as it comes against this notch 55, as shown in FIG. 6 and 7. If at such a position of the hooked end 32 of the lever 52 in the notch 55 the printing lever rf rises, the tubular part “, having seized the stanch /, will be moved by the action of the printing template when it is printed. from the off position, FIG. 11, in the included, FIG. 12, serves as the usual lever system 62, 63, 64, 65 and 66. The lever 66 is mounted on the axis 67 of the printing lever d, through friction clutch and rotates around this axis 67, together with the lever d, if this latter is not held in its initial position shown in FIG. 12. Thus, when printing from a pattern that is in the position shown in FIG. 12, the lever 66 is rotated relative to the lever d, which in the exemplary embodiment shown is utilized to activate the drive lever mechanism driving the paper feed device, and this device has the advantage that the swiveled rod 81 does not need to be brought to the setting roller . it in the direction of the arrow 61, as a result of which the rack bar t moves in the direction opposite to arrow 58, and the paper tape is moved forward to the desired length. This feeding of the paper tape takes place with each printing, until the setting roller / is turned in the direction of arrow 59. If, however, the setting roller / is turned back to the position shown in FIG. 1, then the rod 21 returns the switching lever 27 to the position shown in FIG. 1 and 3, with the front end of the coupling lever 52-55 extending out of the recess 55, so that with the subsequent lifting of the printing lever d, the gear herd is in place, and therefore the bookcase is leached; thus, the feeding of the paper tape is done only if, before, an imprint was taken from the next printing pattern. In the device shown in FIG. 11-14, the device is applied to such an address printing machine, for KOTQpoM, the activation of the setting roller / by turning in the direction of the arrow 5fl is done automatically, it comes to the position for producing the transfer roller /

The rod 21 in this embodiment is fixed to the lever 66, while the rest of the device for transmitting movement to the paper feed mechanism remains the same as in the first example. Action image of naf. The device I-14 consists in the following: when passing through the place of printing the pattern from which the print was not made, parts of the address printing machine occupy the position shown in FIG. 13. If then a template arrives at the same printing site, which also does not produce a print, then the relative position of the levers, rotary 27 and coupling 52-55, does not change, and when lowering the printing lever d, provided that the rack bar does not yet occupies its right end position, it moves in the direction of the arrow 58; then the lifting of the lever d does not, however, cause the return movement of the rail t and, consequently, the movement of the paper tape, since the hooked end 52 of the coupling lever 52-55 still does not enter the notch 55 in the rod. If, however, when lowering the lever d, the setting roller / is rotated, in order to obtain a print from the printing pattern that has come into working position, then the yushi bar 21 has moved, despite lowering the printing lever d, has retracted its position due to the immobility of the lever 66, meanwhile as a tubular boom and moves in the direction of arrow 67, which causes rotation of the pivoting lever 27 near the clutch 26, which lever comes to the position shown in FIG. 12, not allowing the lifting of the lever 55. In; Firstly, when the printing lever arrives in its lower position (Fig. 12.), the hooked end 52 of the lever 62 enters the notch 55 in the rod t and the subsequent lifting of the printing lever d causes the rod t to fall. through the lever 52-55 in the movement of the tubular barbell and, in the direction of the arrow 61, which, in turn, causes the corresponding movement of the rail t to the left. The hook 52, caught when lifting the lever d into the notch 55 in the rod t, remains in this position until the tubular rod and no longer press in the direction of the arrow 61. Thus, it is a fact that the tubular rod and, when lifting the lever d, gradually returns the pivot arm 27 to the position shown in FIG. 14, does not interfere, nevertheless, with the movement of the rack t to the left in its final position. When the rod reaches this end position and the pressure of the arrow 61 stops and, therefore, when the printing lever d is subsequently lowered, its direction of movement changes to the opposite, the coupling lever 58-53 lowers to the dotted position, FIG. 14, in which the pin 55 of the tubular part does not interfere with the movement of the rack t in the direction of the arrow 58 to the right; Reiki movement in the opposite direction during the subsequent lowering of the printing lever d would be performed only if the next printing template kept the lever 66 in the position shown in FIG. 12, 13 and 14, which would entail a repetition of the action described above. skipping and periodically advancing a paper tape in an address printing machine, characterized by the use (Fig. 1, 1 ", 2, 15) of a tube and equipped with a hitch lever 52, 55 and a swivel lever 27 and moving along an articulated toothed sector and rod t by means of t gigi 21 connected to the lever 27 and to the adjusting roller / with the handle 8 in the head g of the printing lever d. 2.
