Description

The invention relates to an address printing machine according to the preamble of claim 1.

Such an address printing machine has become known from DT-OS 22 32 255. With the well-known Address printing machine is the print carrier surface to be printed from an endless paper web formed, which conveyed together with a ribbon in the vertical direction through a printing station will. The printing plates coming from an embossing machine are transversely to the conveying direction of the Paper web moved in the horizontal direction through the printing station, but are in the same way Way as the paper web is paused for printing. In doing so, a pressure wake is generated on a moved horizontally across the printing plates.

Such a printing device cannot be used where it is already finished in a magazine Printing plates on individual print media, such as envelopes for printing should.

An address printing machine for such a purpose is from 1932 original prospectus »Die Adressette« became known. This well-known address printing machine worked with printing forms lined up next to one another in the form of a ribbon, which ran in a vertical direction through the Printing station were passed. For this, the printing station was with a vertically upwards equipped opening receiving gap, in which the addressing envelopes are inserted from above became. The device was equipped with a hand crank, and as far as can be seen, the printing forme conveyor was and the print carrier conveyor is formed by a friction drive with a hand crank. Both the stripes lined up Printing forms as well as the addressed envelopes left the printing station in the downward direction, the addressed envelopes were caught in a pocket while the printing forms were being processed Could free fall through the strip going through the printing station.

Such an address printing machine with individual threading of the address printing form strips and individual feed of the envelopes to be addressed by hand does not meet today's requirements, with the large ones Numbers of addresses are to be printed automatically and possibly even a collaboration the address printing machine should be possible with other data processing systems.

In particular, strip-shaped printing forms of the type used in the known machine are poor and can easily be damaged, mixed up or otherwise incorrectly handled. Man In such a system it is also difficult to skip individual addresses, and still stands also the indiscriminate dropping of those addressed

Envelopes in a collecting pocket inconsistent with the principles of proper handling.

The German patent specification 5 31 338 already has aiich a device for automatically depositing the items fed to the impression point by means of a conveyor drum Address templates disclosed in address printing devices. This device has one above one Print drum arranged magazine, from the lower end of the address printing templates in tangential Direction of the printing drum are pulled off, then after use tangential in one to the upper To be introduced at the end of the magazine leading back guide shaft.

British patent specification 13 523 shows an address printing machine, which also works with printing plates stacked in a vertical magazine. The magazine has an upper part for receiving the printing plates that are still to be printed, and one lower part to accommodate the printing plates that have already been printed. Between these two parts of the Magazine, a slide assembly is provided, which each of the lowermost pressure plate from the upper Pulls out the magazine part and feeds it to the printing station, while the printing plates brought during the printing process withdraws from the printing station and at the upper end into the stack of already printed printing plates introduces. Precautions are taken to move the stack of printing plates for each printing operation to move down a plate thickness and in this way all printing plates one after the other To bring an imprint. In this known device, the slide assembly is in a horizontal position arranged, wherein a pivot lever is provided with a pressure element at the printing station, which with a pressure abutment cooperates to form an interposed assembly of pressure plate and envelope to be printed on top of each other.

The DT-AS 11 74 332 describes an addressing machine, in which a slide assembly, the respective printing plate to be printed below from a vertical Feed chute pulls off and lying on a horizontal path through the printing station to one Storage shaft transferred.

The state of the art also includes d ^; e DT-AS 10 51 292 and US-PS 28 71 781 should be mentioned. These relate to postage stamping machines in which individual letters or the like are layered through a printing device standing in a horizontal path on their lower edge. In the case of stamp devices of this type, the problem does not arise that the movement of the individual printing media must now be precisely matched to individual printing plates from a stack.

Finally, reference is also made to US-P3 27 65 733, in which a card magazine with a Stacks of cards lying on their main surfaces and a printing plate magazine with them on their main surfaces lying pressure plates are provided. The cards and plates from the two magazines will be then introduced together into a printing station and brought there for printing.

The present invention is based on the object of a novel printing machine for the Aare create that with a simple, cheap and space-saving structure an automatic processing of plate-shaped embossed printing forms and printing media, such as B. Turning, permitted. It is intended especially for an easy-to-grip arrangement of the printing plate supply and the printing medium and also the Possibility to be opened up, the printing plates to be imprinted in each case immediately beforehand to watch.

The solution to the problem consists in the combination of the features of the characterizing part of the claim 1, for whose unique characteristics no independent protection is sought.

In the address printing machine according to the invention, the printing plates and printing media are on top of one another crossing tracks with vertical position of their main levels inevitably promoted. The print media are guided through the printing station standing on the edge on a horizontal path, while the Printing plates are stored vertically on the edge in a supply located below the printing station and taken from it for printing. The printing plates are then used for the The printing process is promoted upwards, but first of all arrive in one above the printing station located inspection station, where they can be inspected before they are then on the way back in get the magazine into the print station. This concept leads to a particularly compact table machine, which can not only work completely automatically and is largely foolproof, but beyond that has the great advantage that the individual printing plates can be viewed before printing To be available.

The subclaims relate to advantageous configurations and developments of the subject matter of the main claim.

Below is an embodiment of the invention with reference to the drawings explained:

A printing device 10 is shown in FIGS. 1 to < shown: it has a container 16, inside which several arc-shaped objects, ζ. Β Bric envelopes as print media 18 are stacked in an upright position on one edge. The upright existing print media 18 are conveyed individually from the container H along a horizontal path into a printing station 2. A print carrier conveying device 22 (FIG. 3) is provided for this transport.

Printing plates 26 are in sequence along a vertical path by means of a printing plate conveyor direction (32 F i g. 5) from a removable magazine 28 of the printing station 20 delivered. During a

During the printing run, the data from one of the printing plates 26 is transferred to one of the printing media 18 in the Transfer area of the printing station 20. When the next following print carrier 18 with the help of the print carrier conveyor 22 is moved in the direction of the printing station 20, the printed printing medium 18 becomes discharged through an opening 34 into a receiving trough 36 (FIG. 1). Got during this process the next printing plate 26 into the printing station; the pressure plate 26 used is with the help of Printing plate conveying device 32 returned to the magazine 28 used for printing plate storage. After all the printing plates 26 have been withdrawn from the magazine 28 and delivered to it again, can the magazine 28 of the printing plates 26 removed from a carrier 42 and od in a storage compartment. to be introduced.

The print media 18 are stored within the container 16 so that their sides are vertical extend above; their lower edges lie on a wing 48 (Fig.4), which in the direction of a Control panel 52 runs obliquely downwards. When a print carrier 18 from the container 16 of the printing station 20 to is transferred, an intermittently drivable separating device 54 is switched on by a Electromagnet 56 is energized for a short time to the frontmost print carrier 18 on a continuously driven conveyor belt 86 to pass. This is on the lower edge of the print carrier 18 with its upper run 94.

The conveyor belt 86 engaging the lower edge of a print carrier 18 transports the print carrier 18 standing vertically in the printing station 20. The conveyor belt 86 is continuously driven by a pulley 92 driven.

When the print medium 18 reaches the printing station 20, its leading edge is by contact with a Alignment gap 100 (Fig. 4) stopped, which consists of a pair of rollers 102 and 104 within a Stop device 106 is formed. When the leading edge of the print substrate 18 is in the alignment gap 100 arrives, the print carrier IS is aligned in the longitudinal direction with respect to the printing station 20 and in kept stationary position. The upper run 94 of the conveyor belt 86 slides along the lower one Edge of the upright print carrier 18 (Fig. 5).

The print medium conveying device 22 is in detail Subject of a further application, so that no independent protection is sought for these details.

The print carrier 18 remains in an upright position within the print station 20 during data from a pressure plate 26 are transferred to him. After the pressure is done, it rotates Drive shaft 104 around the upright print carrier 18 through the opening 34 (FIG. 1) into the To lead receiving trough 36. The stop device 106 can be connected to the conveyor belt 86 from the position shown in FIG shown withdrawn in a in F i g. 1 shown extended position can be moved, around different surfaces of a print carrier 18 opposite the pressure plate 26 in the area of Align printing station 20 or to be able to print print media 18 of different lengths.

When a print carrier 18 with the help of the print carrier conveyor 22 transported to the printing station 20 (> <> is benefits, at the same time a printing plate 26 with the help of the printing plate conveyor 32 (Figure 5) in the printing station 20 passed. The printing plate conveyor 32 has a front conveyor 120, which pulls each of the printing plates 26 from the magazine 28 and up into a Inspection station 122 forwards. A rear conveyor 126 in turn engages each of the Printing plates 26 in the area of the examination station 122 and moves them down into the printing station 20. After completion of a print run in which data is transferred from the printing plate 26 to a printing medium 18 have been transferred, the rear conveyor 126 directs the pressure plate 26 into the removable Magazine 28 back.

The printing plates 26 are arranged within the magazine 28 in a predetermined order. Around To maintain order, the printing plates 26 in the magazine 28 are in the same position returned, which they had taken before removal by the front conveyor device 120.

The front conveyor 120 lifts the pressure plates 26 along a pair of vertical rails 130 (Fig. 5) to the top; rails 130 are formed in uprights 132 and 134 (Fig. 3). Though only one of the rails 130 is shown in the stand 134 (FIG. 5), there is a corresponding rail in the Stand 132. It opens outward toward rail 130.

The front conveyor device 120 has a right front pick-up slide (not shown) and a left front take-up slide 138 (Fig. 5). The left and right front pick-up slides 138, hereinafter referred to only as slide, are each in a vertical guide rail arranged, which is formed in one of the stands 132 and 134 and assigned to this. The front Sliders 138 engage the lower edge part of a pressure plate 26 located in the magazine 28 (FIG. 6) and are moved upwards together to move the printing plate 26 from the magazine 28 to an intermediate station 140 and from the intermediate station 140 to the inspection station 122. In a comparable way it has rear conveyor 126, a right rear return pusher (not shown); and a left rear return slide 144 on the slide 144 are in vertical rearward The rails of the vertical uprights 132 and 134 are slidable. Only the rear rail 148 for the rear left slider 144 is shown in FIG. 5 shown. The two rear slides 144 slide a pressure plate 26 vertically out of the inspection station 122 down into the printing station 20 and from the printing station 20 back into the magazine 28.

The front slide 138 have a lower end portion 152 which extends over a longitudinal direction extending connecting portion 156 is connected to a main part 154 Slide 138 into the position shown in FIG. 6A is moved downward, the connecting portion 15f elastically deformed backwards when a « Tab 160 on the inner surface of a pressure plate 26; (Fig.6A) attacks When the slide 138 nact Moved at the bottom, the nose 160 slips into a groove located on the side of the pressure plate 26a, around the horizonta Grip the lower edge part of the pressure plate 26a securely.

Simultaneously with this abutment, the lower end portion 152 of the slide 138 moves against the pressure plate 26a the upper end portion 162 of the slide 138 under the horizontal lower edge portion one in the middle

station 140 located pressure plate 266. The upper end portion 162 of the slider 138 is connected to the body or main part 154 of the slider 138 via an elastic and deformable connecting part 166th The connecting part 166 is deflected in a rearward direction by the contact of the upper end part 162 of the slide 138 on the pressure plate 26b when the slide 138 moves into the receiving position shown in FIG. 6A.

When the front slide 138 is moved upward from the position shown in FIG. 6A into the position shown in FIG. 6B, the nose 160 lifts the pressure plate 26a out of the magazine 28 into the intermediate station 140. When the pressure plate 26a moves vertically upwards in the direction of the intermediate station 140 , it pivots a lever 167 clockwise ( Fig. 5), the lever 167 rotating about an axis 168 against the action of a tension spring 169 . After the lower edge of the pressure plate 26a has moved upwards via the lever 167 , the tension spring 169 rotates the lever 167 counterclockwise (according to FIG. 5) around the shaft 168. This movement places the lever 167 under the pressure plate 26a, to prevent downward movement of the printing plate out of the intermediate station 140 .

When the pressure plate 26a moves into the intermediate station 140 , a pressure plate 260 simultaneously moves from the intermediate station 140 (FIG. 6A) upward into the inspection station 122 (FIG. 6B). When the pressure plate 266 moves upward in the direction of the inspection station 122 , a lever 170 is pivoted in a clockwise direction (FIG. 5) about an axis 171. When the pressure plate 266 moves up past the upper end of the lever 170 , it rests on a pivoting support plate 174 (FIG. 5) in the inspection station 122 . The lever 170 is spring-loaded so that the upper end 172 of the lever 170 moves back into contact with a stop 178 as soon as the pressure plate 266 has come free from the upper end of the lever 170 . The lever 170 then rests against a lower edge part of the pressure plate 266 and holds it in the position shown in FIG. 6C, ie on the support plate 174 (FIG. 5) in the inspection station 122.

Simultaneously with this vertical movement of the pressure plates 26a and 266, which runs upwards in the direction of the intermediate station 140 and the inspection station 122 , the preceding pressure plates 26c and 26d are transported downward by the rear slide 144 Inspection station 122 (FIG. 6A) on a printing plate 26c and moves it downward into the printing station 20 (FIG. 6B). When the printing plate 26c is moved into the printing station 20, the printing plate 26c / is pushed by the rear conveying device 126 from the printing station 20 (FIG. 6A) into the magazine 28 (FIG. 6B). When the pressure plate 26c / has been returned to the magazine 28, its rear side is in level contact with the front side of the pressure plate 26c /, which immediately precedes it within the row of pressure plates 26 in the magazine 28.

In order to enable this vertical downward movement of the pressure plates 26c and 26c /, the rear slide 144 is provided with an upper end portion 186. '■ which engages the horizontal upper edge of the pressure plate 266 when the rear slide 144 moves downwards. Simultaneously with this, a lower end portion 188 of the rear slide 144 rests against the horizontal upper edge of the pressure plate 26c . When the rear slider 144 is moved downward from the position shown in FIG. 6A to the position shown in FIG. 6B, the upper end portion 186 of the slider 144 pivots the support plate 174 (FIG. 5) and the pressure plate 26c against the Clockwise to guide the pressure plate 26c into a vertical guide rail 194 (Fig. 5). During this downward movement of the rear slide 144 , the lower end portion 188 of the slide 144 initiates the movement of the pressure plate 26c , which is countered by the printing station 20 the effect of a spring-loaded support lever 1% (Fig. 5) runs downwards. For this purpose, the support lever 1% is pivotably mounted on an axle 198 . The continued downward movement of the rear slide 144 has the consequence that the printing plate 26c moves from the inspection station 122 into the printing station 20 and the printing plate 26c / is transported from the printing station 20 back into the magazine 28 . As soon as the pressure plate 26c / is free from the support lever 196 , the latter swings back under the action of a tension spring 199 in order to support the pressure plate 26c . The front and rear sliders 138 and 144 sit on ropes, as indicated at 208 , and are moved up and down together by means of a slider drive device 200 (FIG. 4) in a manner not to be explained in greater detail here: the slider drive device is in turn set in motion by a main drive motor 202 (FIG. 4).

Although only the connection between the slide drive device 200 and the left slide 138 and 144 is shown, the same arrangement is of course also present for the right slide.

Every time a pressure plate 26 is removed from the magazine 28 , the magazine 28 moves as shown in FIG. 5 to the right in order to bring a subsequent printing plate 26 into a position in which it can be gripped by the printing plate conveying device 32 during the next run thereof. In order to trigger this backward or inward movement of the magazine 28 , the magazine 28 is arranged on the movable carrier 42 , which is continuously pulled inward by means of a tension spring 224 (FIG. 5). The tension spring 224 is connected to a frame 226 of the carrier 42 which extends in the longitudinal direction.

Each time a pressure plate 26 is removed from the magazine 28, an adjusting device 230 ( FIG. 5) releases the magazine 28 so that it executes a movement corresponding to the thickness of a pressure plate 26. In this way, the next pressure plate 26 is in vertical alignment brought with the front conveyor device 120 so that the lower end portions 152 of the slide 138 engage the next following pressure plate 26 during the next downward movement of the conveyor device 120.

The setting device 230 (FIG. 5) has a front, leading setting lever 234 which engages the rear or inner surface of the next pressure plate 26, which is to be withdrawn from the magazine 28. The inside of the setting lever 234 rests against a stop 244 , to hold the magazine 28 and the carrier 42 against a rearward movement under the action of the tension spring 224. However, as soon as the printing plate conveying device 32 removes a printing plate 26 from the magazine 28

withdraws, allows the gap created by the removal of the pressure plate 26 that the Extension spring 224 pulls magazine 28 backward against front surface 238 of adjustment lever 234. Of the Adjustment lever 234 is pivotably mounted on the axis 168 so that the adjustment lever 234 is free in the Turn clockwise (according to FIG. 5) in the direction facing away from the stop 244 and out of the magazine 28 can be pivoted out when the magazine 28 is removed from the printing device 10 target.

The pressure plates 26 returned to the magazine 28 are held by a holding lever 248 of the adjusting device 230 (Fig. 5) braced backwards. The holding lever 248 can be pivoted with the setting lever 5 234 mounted on the axle 168. The retaining lever 248 is braced rearward (i.e., against the Clockwise according to FIG. 5), since it is under the influence of a tension spring 250.

A printing device 260 (FIGS. 4 and 5) in the area of the printing station 20 prints between the work cycles of the printing plate conveying device 32, each of the printing carriers 18 with one of the different ones Printing Plates 26. The printing device 260 operates with a printing roller assembly 262 which runs along a Support rod 264 is moved from right to left (according to FIG. 4) around the pressure roller 266 assigned to it to move over a platen 270 during a print run. The pressure plate 26 is located in the Printing station 20 in the area between the platen 270 and an ink ribbon 274.

When the platen assembly 262 has reached the end of its leftward travel (as shown in FIG. 4) reached, the platen 266 is pivoted to a retracted position. The pressure roller assembly 262 is moved from left to right during the return movement, with the pressure roller 266 moving at a distance from the print carrier 18 is located. During this return, the drive roller 104 is in the holder 106 for Print carrier stop and print carrier output rotated at a relatively high speed in order to achieve the the printed print carrier 18 through the opening 34 in front of the printing station 20 into the receiving trough 36 convict. When the printed printing medium 18 has left the printing station 20, it moves The next following print carrier 18 under the action of the conveyor device 22 in the direction of the printing station 20 In addition, the printing plate conveying device 32 is put into operation for a subsequent printing plate 26 to lead into the printing station 20.

The platen 266 is driven by a drive device 27i during the print and return runs (Fig. 4) moved forward and backward. The drive device 278 is for this purpose via cable 280 ar the platen assembly 262 connected. The drive device 278 is in turn by the Main drive motor 202 driven. Since both the drive device 278 and the pressure plates Conveyor 32 are driven by the main drive motor 202, the mutual synchronism run of the two devices reached. The print carrier conveying device 22 is also corresponding Voted.

Each time the platen roller 262 completes a print run, a ribbon feed device becomes 290 put into operation. The ribbon feed device 290 is of known construction unc causes the ribbon 274 to cover the same movement segments when it is actuated. Thereby wire the ribbon 274 is withdrawn from a spool 292.

When a pressure plate 26c is in the inspection station 122, it is illuminated by a lamp 298 is the operator of the printing device 10 kla visible. If the operator does not wish, mi To work this pressure plate 26c, it can operate a snap switch on the control panel 52, so that the printing device 260 is not put into operation when this printing plate 26c the printing station 2 ( achieved.
