Printing machine

The present invention relates to "printing machines.

Until recently, sales slips were entirely handwritten, a carbon copy was issued for the customer. then embossed metal plates came into use for accounting purposes in department stores; this eventually became minted credit cards Developed from plastic material of known type. In these

Cards are information other than the customer's name

contain; The cards are used as data carriers in printing machines, a pressure roller being pressed against the surface of the plate via a set of carbon paper in between. Other information was handwritten on the form before the deal was completed.

Machines have been developed such as those described in U.S. Patent 3,138,091 to J.A. Maul are described in which find several pressure wheels with an Anaahl of pressure areas use. There is one on each of the surfaces of the print wheels different print marks arranged, piese print marks are kept in a group and in line with the credit card being printed. Thus, variable information such as the dollar amount of the transaction, encrypted in the form together with the fixed information at the end of the printing cycle be applied. The use of variable pressure elements together with fixed pressure elements enables the printing process of this information in order to avoid manual entries.

Printing machines of this type were used on a large scale for tank ' jobs were created, but were also widely accepted in industry and hospitals. For example, a Printing press of this type are used to produce the Kenneeichnungakarte of the employee, the master's code card and the identification and code cards of the particular job or

00988370056 _ ₃ _.

Combine machine su. These identical cards are placed in alignment with one another on the platen of the machine and printed together on an encryption sheet. The employee only works occasionally a certain number of hours or does some work for a certain number of pieces before going this work changes. The machine's variable print mark area is provided for this purpose. In some cases, however xvrder variable print characters only at the beginning or at the end of the work process, in some cases not at all. The devices that hold the variable information carry, but are limited in their capacity and the dimensions of the machine are adversely affected, if a completely bare print point is used on these printing devices, there is another solution in using two printing machines, one with one longer printing cycle than the other.

The present invention seeks to provide a printing press of the type set forth above US patent is shown; variable data carriers are used, whereby the print head of the machine is opened, before it reaches the variable entries. After setting by the operator, the print head can also be held until it goes through the field of variable entries

009883/0056

has run. Therefore, if the operator does not wish to use the variable entries, he can can be determined by the printhead opening after the platen has traversed only part of its path Has.

In the drawings, a printing machine according to the present invention with interchangeable printed characters is shown in FIG Combination with variable pressure hulls shown. The pressure roller controls the release of a locking device for the print head, wherein according to the present invention an intermediate piece is provided, which the print head before the end of the printing cycle opens, so that the variable pressure body is printed or optionally left out can be.

The invention is explained with reference to the accompanying drawings.

The present invention relates to printing machines known type. In order to shorten the description of the present invention, only the necessary "components of an ordinary printing press * For a complete understanding of the printing press, however, refer to U.S. Patent 3,138,091 to Maul. About the relationship To indicate this earlier patent, like reference numerals have been used for like parts in the present one Invention adopted. The parts not belonging to the present invention are not listed.

In the drawing, an embodiment of a print length selection device according to the present invention is shown. The printing machine is identified by the reference number "} \ beaseichnet" and consists of a base part 32 and a print head 33. The print head 33 is rotatably mounted on the base 32 so that it can be in a printing position on the.

009883/005

Base part can be lowered and raised again from this pressure position. In FIG. 1 the print head is in the raised pressure rest position : Although the associated parts are not shown in FIG. 2, this shows the print position in which the print head is lowered.

As can be seen in Fig. 1, there is a pressure point slightly above the middle between the sides of the base part. The pressure point is limited on the opposite sides by guides 48 and 49 in order to like embossed metal or plastic cards.

A number of optionally adjustable printing type bodies in the form of encrypted wheels 63 are on the base part 32 attached, and are aligned with respect to the pressure point in the illustrated embodiment. For the present Invention, the use of print wheels is not essential. It is enough to have an elongated, single Use pressure hull with data atu located on the end part, these data temporarily not being used for the Pressure can be used. Print wheels and variable printing devices are known and therefore do not require one further explanation.

The outer frame of the printhead 33 has a pair of side plates 79 and & 1 which pass through. U-shaped ^: guide bodies 82 are connected to one another. A square rotating rod 84 extends between the side bodies 79 and 81 and is rotatably supported on the base part 32 within the side bodies thereof. The base body 32 can thus close by a rotary movement of the print head 33. S.

A platen device within the printhead 33 can be moved manually above the printing point 44 and transversely to it, around those on a card or on cards To transfer records at the printing point to a form, which is inserted between the print head and the base part of the machine. The platen device has a pressure roller 86. This pressure roller can work in the dampening process or in the dry process, where J

in the latter case a band is stretched over the printing area. A bracket 87 includes the guide 82. The pressure roller 86 is within the lower ends of the downward 8-7 standing bracket arms attached. The bracket can be moved along the greater length of the guide 82. The movement of the bracket is designed in such a way that that the pressure roller moves in a path, the end of which

009883/0056

points correspond to the length of the pressure point carrying the card or cards. A handle 89 is used for manual operation of the bracket 87 · The print head 33 is Um the pivot rod 84 is rotatable between closed and open positions; in the closed position if the pressure roller is in pressure engagement with pressure bodies inserted at pressure point 44 of the base part, hk while in the open position the pressure roller out of its Pressure engagement is released.

By means of a locking device, the print head becomes rigid in its printing position during the printing process locked. The locking occurs when moving of the printhead from its raised position to its lowered printing position. This locking device is arranged in such a way that it holds the printhead in its printing position until the platen moved enough to complete printing; if the pressure roller continues to move, the Locking device released in order to raise the print head into its upper pressure rest position shown in FIG.

The locking device is shown in detail in FIG. A pair of latch bodies IO3 and 104 is

009883/0056

rotatably attached to the outside of the guide 82. Eihö rod 111 forms a connection between the two
Pawls »so that they are effective as a single unit tfefdSh. In the drawings not shown springs press the
Pawls on top of each other. A pair of Änsätaön 117 and 118 are arranged in the base part 32, and were engaged by pawls 103 and 10h when the pawls are turned down to the pressure position. The upper surfaces of the lugs 11.7 and 118 are somewhat beveled, as are the lower and inner edges of the pawls 103 and 14. This rotates the lower ends of the pawls outward during the downward movement of the printhead. When the printhead has been lowered sufficiently, the spring, not shown, is effective to move the pawls 103 and 104 inward into their locking position
to be pressed elastically. The print head is thus held until the locking pawls are released from each other at the end of the .Druck cycle of the λ print roller.

The major improvement of the present invention is contained in a device which, as a function of the pressure roller movement, moves into a specific release position is movable along the aligned letters to cancel the clamping effect of the pawls.

Reference is made in particular to FIGS. 2 and 4 below taken. Since the pawls through the rod 111 with each other connected, they act as a single interlock. The pawl 1ö4 is in the path of movement of an arm of the bracket 87, so that with the help of the handle 89 brought about movement of the bracket this into the Proximity of the latch 104 brings. A stop 120 is located on one arm of the bracket 87 in order to actuate the pawl to form a sufficient contact, the locking elements are thus at the end point of the pressure roller movement, to be moved into their release position, whereby the printhead is released at the end of the printing cycle. For no operator is required to release the printhead. After the individual printing bodies or printing elements7 the form with temporary storage is placed at the printing point 44 are placed, the print head 33 is closed in its Position rotated. It remains in this closed position until the pressure roller is completely over the pressure point or over the Plunger was moved away. It is impossible that the printhead can be loosened before the entire one Printing has ended. This means that the entire information available in the mix is printed with the same Clarity guaranteed.

For industrial purposes, however, it is necessary that the Druokmaeohine of the present species is not a complete

Pressure cycle is carried out. If, for example, the variable pressure wheels are used at the end of the pressure hulls, then these can be used to display the start or end of a work segment, see the display of a number of pieces produced during a segment, or for other data. When a worker begins his work, for example, he uses his identification card, while the foreman can attach his identification number to that of the worker; Then the variable printing device can be set at the end of this printing information, for example to show the start of work or other variable values. In this way, personal, handwritten entries are avoided, while clearly recognizable, printed letters with uniform print quality are avoided achieved.

Although most printing uses variable Printing elements is required, so cases are conceivable in which this is not the case. For example, the worker can to approach a work which does not contain variable information underlying. For example, the variable information may only be required at the start of work or at the end of work be, whereby a further pressure with the variable Wjadergabe is not necessary.

According to the present invention, an intermediate body is provided, which is in a first position in the path of the bracket to exert a force on the pawl 104, before the bracket was moved to the end of the printing cycle. The intermediate body can be rotated with respect to a stop, in which it is in the operative position, the print head being opened with normal movement of the bracket.

Although the print head 33 cannot be released as long as not the pawls 103 and 1 04 are turned outwards, and although this does not take place until the stop 120 reaches the pawl 104, the pressure roller can, before it reaches the end part the pressure point has reached 44, can be stopped with the help of the intermediate body. The pawls can at this point can be released in order to interrupt the printing process by the pressure roller from the printing engagement before the end of its printing cycle is resolved.

In particular, the intermediate body 122 ^ as shown in FIGS. 3 and 4 to. can be seen, slidably mounted on a rod 124. The rod 124 preferably has a non-circular shape Cross-section, so that the intermediate body on lugs 126 and 128 located at the end, which likewise do not circular openings are provided, fixed and thus in certain longitudinal position can be held. In particular, the rod 124 has a square cross-section. By wacky

A pivot point is formed in sections 13O. If you have the * Intermediate body moved in such a way that the lugs 126 and 128 are flush with the turned-off sections 13O, the intermediate body between the in Fig. 3 and Flg. 4 position shown can be rotated. A spring 132 displaces the intermediate body in a stop position on the side body 81; however, the contact pressure of the spring is weak enough so that it can pass through the Finger of an operator can be overcome. ™

The strength of the spring 132 is less than necessary to the pawls 103 and 104 against the tension of their springs to press. Due to the arrangement of the intermediate body in the position shown in FIG. 3, it is therefore in a short distance from the side body 81, which can be seen in FIG.

The operator moves the intermediate body along the i Rod 124 until it can be rotated. The intermediate body is always rotated into the position shown in Fig. 3 when the pressure cycle of the pressure roller is to be shortened. He is rotated to the position shown in Fig. 4 during normal printing operation when a full printing cycle is required.

The intermediate body is in the position shown in FIG. 3 in the movement of the pressure roller, whereby the stop 120 on Adjoining interstitial body.

009 883/0 058

When the stop 120 comes into contact with the intermediate body transmit the contact force to the pawl 104. The intermediate body therefore moves along the rod 124 until it adjoins the side body 81. When he has reached this point, the pawl 104 has moved enough to the Release printhead. The intermediate body therefore serves primarily as a release device and not as a holding device, although it does prevents the print roller from moving to the end of its print cycle.

When the bracket 87 strikes the intermediate body, it moves it against the side body 81 when the pawl is opened. The purpose of this arrangement is that the handle 89 should not be used to strike the pawls with too much force. Superfluous force is therefore limited to the contact between the intermediate body and the side plate.

The machine of the present invention performs the functions of two masohins. The printing point or the pressure abutment kk is used for printing conditions, while the abbreviated printing cycle can be used for other printing conditions. This shortening of the printing cycle saves the costs of a second required machine.
