Definitions
- the present invention is concerned with the fundamental problem of how to supply envelopes for printing to a printing press without causing work to be interrupted or stalled. If, for example, a stack of envelopes is placed on a printing press for printing, then it will be moved at a relatively high speed, e.g. B. by means of a suction arm, these envelopes are lifted off individually in the printing cycle and fed to the actual printing process. So that one can now put more envelopes from the additional boxes, the machine would have to be switched off. In order to prevent this, one is forced to design envelope feeders that continuously deliver envelopes to the printing press without the printing press having to be interrupted.
- 1st variant In this variant, the printing press and the envelope feeder are assembled as a single compact machine. There is therefore no possibility for use on other printing presses.
- 2nd variant The envelopes are removed individually using suction rods or suction plates, which then have to go in sync with the printing press. However, this synchronous running device available on the market only fits a single commercially available printing machine and is therefore not compatible with others.
- 3rd variant Another envelope feeder is partially compatible. However, it works with a rubber band, which has the consequence that a very large spread is obtained in the scaling. In addition, there is the fact that this envelope feeder, like all the others already mentioned, transports the envelopes alongside, ie the envelopes precede with the short side and the envelope cover is then not on the front but on the side.
- this envelope feeder cannot be used for sheetfed offset presses that are intended for A 3-format sheets.
- the envelopes can no longer be taken over by the scale feeder of this printing press because the width of the preceding narrow side is too small. This applies especially to the C 6 envelope.
- the market gap mentioned here can now be filled with the present invention by constructing an envelope feeder which can also transport the envelopes transversely, ie. H . with the broad side ahead. It was thus possible to build an envelope feeder that can be used for practically all printing machines.
- the first problem was to solve the problem of how to construct an envelope feeder at all, which works very reliably with a very small scaling distance of, for example, less than 2 cm and has only low scatter values. As shown in Fig. 1, this is especially necessary for self-adhesive envelopes 1, which only have a very narrow cover strip 2 of approx. 2 cm.
- Fig. 1 b) can we see what happens when the distance as shown in Fig. 1 a) was too large.
- the subsequent envelopes 1 are erroneously pushed under the cover 2 of the previous envelope when the storage beige 8 is formed.
- Fig. 1 d) it is shown how the envelopes come to lie nicely on one another again if only a small overlap distance was selected, as in FIG. 1 c).
- Fig. 2a it is shown how the bottom envelope is drawn in by the vacuum chamber 3. The result of this is that it sticks to the conveyor belt 4 and is pulled away from it. As soon as the rear edge of the envelope has moved to the right enough, the suction effect can also be exerted on the second bottom envelope.
- Fig. 2 b) exactly this borderline situation is shown and in Fig. 2 c) the second lowest envelope has already been seized by this suction effect and likewise moves to the right with the lowest envelope, the second envelope being offset to the right by the shingling distance 5 from the first envelope.
- the negative pressure is too high (e.g. 50 mbar), two envelopes are pulled away at the same time, while less than half of this value guarantees perfect functioning.
- FIG. 2 shows clearly how the scale distance 5 can be set very easily, because it also corresponds to the distance between the left edge of the vacuum chamber and the left edge of the envelope 1.
- This scaling distance can now be deliberately and specifically varied by moving the envelope beige to the left or to the right. This can be accomplished very easily with the displaceable barrier and the simultaneous stripper 6 (see FIG. 3), because this barrier or stripper 6 can be displaced to the left and right and can then be fixed in any position.
- the wiper 6 can also be shifted in height and can be fixed again in any position.
- the task of the envelope feeder is now to form a storage beige 8 (see FIG. 3), from which the scale feeder of the printing press can remove envelopes at the top at any time.
- This storage beige 8 is achieved in that, in the case of a beige, further envelopes are continuously pushed in at the bottom, and the beige is therefore always larger if the envelopes are not continuously removed from the scale feeder of the printing press again at the top. So that this storage beige cannot nevertheless become too large, it is provided with a light barrier so that the envelope feed can be electronically controlled in this way.
- a photocell can also be installed at the refill beige 11, which emits a signal as soon as you have to refill.
- the hold-down roller 7 also belongs to this invention immediately before the storage beige 8. It ensures that any air that may be present is pressed out of the envelopes. With this addition, an old evil can be eliminated, which up to existed with the previous machines. As soon as the excess air was squeezed out when printing the envelopes, the paper fluttered and, as a result, a blurred and blurred print. With the hold-down roller 7 mentioned, it is ensured from the outset that there is no more air during the printing process, and as a result a high printing precision is achieved during the first pass.
- the present invention has succeeded in constructing an easily adjustable envelope feeder which no longer knows the disadvantages of the existing ones, because it can be used for practically all printing presses without synchronization with the printing press machine is necessary and because it is possible to transport the envelopes with the broad side ahead on the conveyor belt thanks to a precisely adjustable, precise clutch.
