DE656150C - Multi-color printing press with a back and forth, the printing blocks, sentence forms or the like. carrying cart - Google Patents

Description

The invention relates to a multicolor printing press with a reciprocating, the printing blocks, sentence forms or the like. Carrying trolleys, several in the press frame as a function inking rollers that can be moved vertically by the movements of the cart and a transfer cylinder that can be raised and lowered.

According to the invention, the transfer cylinder or cylinders of the press are inevitably rotatable arranged in a swivel arm. The swivel arm is adjustable by an eccentric and its downward movement can be regulated by an adjusting screw. The Farhzufuhr- and distribution rollers are in a housing attached to the machine frame and the Inking rollers in a guided underneath the housing on the machine frame, inevitably liftable frame rotatably mounted.

ao The frame carrying the inking rollers hangs on rollers that are either on separate Surfaces of the cart or attached to the cart, curved at one end bent rails run.

In the drawing, the invention is shown in one embodiment, for example, namely show:

Fig. Ι a side view of the machine, but without the drive means for the transfer cylinder,

Fig. 2 is a view of the machine seen from one extreme end,

Fig. 3 and 4 individual representations of the drive means with an arrangement of two transfer cylinders in side and front view.

On the machine frame 1, a cantilever arm 2 is attached to the cart 3 in to support its end positions. A rack 4 is attached to the cart 3, in which engages a gear S mounted in the frame 1. In the cart 3 are the sentence forms, printing blocks 10 or the like. As well as the one to be printed Item 26 attached. The cart 3 is deposited over its entire length near its surface on both sides, so that running tracks 3 'arise. On these are from one end of the cart 3 to over the

Middle reaching rails 14 attached, whose one end 1: 4 'is bent in a curve, the gear 5 is with a pinion in Engagement, on the shaft of which a pulley 6 is seated, from the power source afjf is driven. By a second on dej? 5i The belt pulley seated on the same shaft becomes the ink feed rollers via an intermediate bracket 7 driven, which are mounted in a housing 9 attached to the frame ι. Under the rollers 7 are the paint distributor rollers 8, while above the rollers 7 the Paint containers are arranged.

Through the guides attached to the frame 1 13 a frame 12 adjustable in a vertical plane is guided in the inking rollers 11 are arranged, which have the same distance as the ink feed rollers 7 and 8 distributor rollers. The frame 12 carries rollers 15 which on the remote surfaces 3 ′ of the cart 3 or on the rails 14 attached to the cart 3 be able to walk.

In the machine frame 1 are also on a shaft 18 (Fig. 3) arms 17 pivotably mounted in which the transfer cylinder 16 is rotatably mounted. The arms 17 are pivoted up and down by an eccentric 19 rods. By a Screw 20 can control the movement and thereby the respective pressure of the transfer cylinder 16 are regulated. A gear 21 fixed on the shaft 18 is of a motor o. The like. Driven and transmits through the intermediate gears 23, 22 the Rotation on a gear wheel seated on the shaft of the transfer cylinder 16.

In the embodiment according to FIGS. 3 and 4, there is also a second arm 17 in the arm +0 transfer cylinder 24 arranged by 'an intermediate gear 25 of the gear 21 is driven. The machine thus has a twofold effect by being in motion of the cart 3 from left to right of the transfer cylinder 16 and the reverse Movement then the other transfer cylinder 24 comes into effect. The cart 3 must then have twice the length, thus corresponding to twice the number the objects to be printed 26 a double area is available.

The surface of the ink feed rollers and the transfer cylinder is expedient made of hard rubber or the like.

The machine works as follows:

After the paint containers with the. relevant colors are filled in order to feed the ink feed rollers 7 and to ink the printing blocks 10, the set form or the like, and after the object 26 to be printed is fixed in the cart 3, the machine is driven by the transmission 6, 5, 4 in Movement set-J, whereby the cart 3 is moved horizontally from the cantilever arm 2 to the right in Fig. 1 over the frame 1. Here- ^ ■ _t ! .L% i the rollers 15 of the frame 12 first run on the stepped surfaces 3 'of the cart 3, so that the frame 12 assumes its lowest position and the inking rollers 11 stored in it with the printing blocks , Sentence forms. 10 or the like. Come into contact in order to supply them with the desired color. Shortly after the printing blocks, set forms 10 or the like have been inked, the rollers 15 hit the bent ends 14 'of the rails 14 and now run on the surface of the rails 14. The frame 12 is thus lifted and brings the inking rollers 11 with the - Distributor rollers 8, which have received ink from the ink supply rollers 7, in contact, whereby the rotation of the ink supply rollers 7 by the main drive causes ink to be delivered to the distribution rollers 8 and through them to the inking rollers 11.

When the cart 3 moves further, the colored sentence forms, printing blocks, come 10 or the like then one after the other with the transfer cylinder 16 in touch and transfer the pressure in the relevant colors on cylinder 16. Are on the transfer cylinder 16 transfer all colors from the printing blocks or typesetting forms 10 has been, the arm 17 is moved downwards by the eccentric 19, so that the transfer cylinder 16 with the corresponding pressing pressure with the object to be printed 26 in Touch comes, which now receives the imprints in the different colors at the same time, which are on the surface of the cylinder 16, creating the desired Multi-color printing is achieved. Only now is the direction of movement of the cart 3 vice versa, the transfer cylinder 16 being raised by the eccentric 19. Shortly before the end of the backward stroke of the cart 3, the rollers 15 run from the Rails 14 from on the surfaces 3 ', whereby the frame 12 is lowered and the colored inking rollers 11 with the associated printing blocks, sentence forms 10 or the like. Come into contact.

By adjusting the screw 20 by hand, the contact pressure is between the transfer cylinder 16 and to printed object 26 regulated, because by the screw 20 independently of the Effect of the eccentric 19 the inclination of the arm 17 can be changed.

If the machine is to work double-acting, the mode of operation is the same. at

the reverse movement of the cart 3 then comes the transfer cylinder in the same way 24 to the effect.
