Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an ink roll having a cylindrical ink carrier and end plates attached to both end faces of the ink carrier and having a diameter larger than the diameter of the ink carrier. A device for receiving and manipulating an ink roll, the ink roll being fixable with its end regions in a U-shaped receiving member by a snap-clamp connection; The present invention relates to a printing machine which can be attached to and detached from a holding member consisting of an arm and a slit.

BACKGROUND OF THE INVENTION Ink rolls are used in printing machines to ink the type prior to carrying out the actual printing process. For example, German Patent Application No. 2502108 describes the use of an ink roll in a manual labeling machine, in which case the ink roll is It is designed to apply ink to the type placed on a printing device installed in the pasting machine. Ink rolls as described above can also be installed in stamps operated with automatic type inking devices.

Once the ink impregnated in the ink roll is printed on a certain surface, it almost never comes off. Due to the properties of this ink, which are desirable in themselves, when handling the ink roll,
In particular, when exchanging a worn-out roll for a new roll, the user's fingers or clothes may become soiled and cannot be removed, and in order to avoid this, special care is required.

OBJECT OF THE INVENTION The object of the invention is to provide a device which makes it possible to cleanly store and handle new and used ink rolls.

According to the invention, this object is achieved by providing two U-shaped shells connected to one another, the width of which at the open end is the width of the ink roll to be received. and the depth of the shell is the same as the diameter of the end plate of the ink roll to be received, and on each end side of the shell there is a resilient elastic member which acts as a clamping part for said end plate. The outer width of one shell member is uniform throughout its depth, while the outer width of the other shell member is closed from its open end. The solution is that they widen towards the ends, so that a spreading effect is produced on the retaining member arms upon insertion of the shell into the retaining member.

Effects of the Invention With the device of the invention, it is possible to remove a used ink roll from a printing machine without having to touch it with one's fingers. Furthermore, in this regard, a new ink roll held by the device in question can also be loaded onto the printing machine without directly touching the ink roll. Also, since the used ink roll is kept in a relatively protected position within the inventive mounting, the risk of inadvertent contact is extremely low.

Embodiments Advantageous embodiments of the invention are defined in claim 2.
As described in Sections to Sections 4.

The ink roll receiving device 1, which is shown in end view in FIG. 1 and in sectional view in FIG.
It has letter-shaped shells 2, 3 which are adapted to each receive one ink roll 4, which is indicated in phantom in FIG. The ink roll 4, clearly shown in FIG. 4, has an ink carrier 5 and end plates 6, 7 mounted on both end faces of the ink carrier 5. The width of the ink roll 4 measured up to the outer surfaces of the end plates 6, 7 is designated by the symbol B, and the depth of the ink roll is designated by the symbol T. Two bearing pins 8 project from the end plates 6, 7, one of which is shown in FIG.

According to FIG. 1, the above two shell members 2, 3
are connected to each other by webs 9, the width of which is reduced towards the shell part 2 for reasons explained below.

The inner surfaces of the shell members 2 and 3 have an inner diameter 11 in the main section 10 of each shell member between the legs 12 and 13 and between the legs 14 and 15 that is larger than the diameter of the ink carrier 5 but that the end plate 6 and 7. The width of the main section 10 corresponds to the width of the ink carrier 5.

On both sides of the main section 10 of each shell member 2, 3, narrow elastically flexible sections 16, 17 and 18, 19 are provided, for example by notches, in which the inner diameter 20 corresponds to the diameter of the end plates 6, 7 and serves as a covering part with a clamping effect for the end plates 6, 7, as will be explained below. As can be seen in the partial view of FIG. 3, the inner surfaces of the legs 12, 13, 14, 15 are arcuate in this section 16, 17, 18, 19 in order to adapt to the outer surfaces of the end plates 6 and 7. has been done. In this case, this arcuate shape is the ink roll 4
, which terminates at a point 21 located above a central plane 22, indicated by a dash-dotted line in FIG. Also category 1
two legs 12 in 6,17 and 18,19,
The distances 13 and 14, 15 widen in a funnel-shaped manner starting from said point 21 towards the open ends of the shells 2 and 3.

Each leg 12, 13 and 14, 15 of shell members 2 and 3 only in sections 16, 17 and 18, 19
The inner diameter 20 of the space between them corresponds to the diameter of the end plates 6, 7 of the ink roll 4, whereas the inner diameter 11 of the main section 10 of each shell 2 and 3 corresponds to the diameter of the end plates 6, 7 of the ink roll 4. The purpose of this is that the ink roll 4 is held against axial movement within the shells 2, 3 and that the end plates 6, 7 are designed to be smaller than the diameter of the sections 16, 17 or 1
8, 19 so that it can be fitted into the shell members 2, 3 accurately at a prescribed position where it should be in contact with the shell members 8, 19.

In the shell member 2, its outer surfaces 23 and 24
extend parallel to each other at a distance corresponding to the width B of the ink roll 4. However, shell member 3
The distance between the outer surfaces 25 and 26 increases from the open end with a width B towards the U-shaped closed end.

The ink roll receiving device 1 initially has in its shell 2 a new, unused ink roll 4 which is to be inserted into the printing machine as a replenishment for the used ink roll. In this case, the ink roll 4 is held in the shell 2 at its end plates 6, 7. At this time, the clamping action is performed by the sections 16 of the legs 12 and 13, as described above.
This is brought about by the fact that the inner surface in the area 17 is arcuate up to a point 21 which lies above the central plane 22 of the inserted inking roller 4. The insertion of the ink roll 4 into the shell 2 therefore takes place with a snap action after the legs 12 and 13 have been slightly spread apart.

The used ink roll 4, which is now located in the holding member with two arms 27, 28 of the printing machine shown in FIG. If it has to be replaced, the used ink roll 4 must first be removed from the corresponding holding member. For this purpose, the shell part 3 of the ink roll receiving device 1 is mounted from above in FIG. 4 onto the ink roll 4 in the holding part. At this time, the outer peripheral surfaces 25 and 26 of this shell member 3
Since the distance between the arms 27 and 2 corresponds to the width B of the ink roll 4 at the open end of the U-shape, the outer circumferential surfaces 25, 26 at this open end
It is brought into contact with the inner surface of 8. When the ink roll receiving device 1 is subsequently moved further towards the ink roll 4, said obliquely extending outer surface 25,
26 causes the arms 27, 28 to widen, and finally the shell part 3 is snapped onto the end plates 6, 7 of the ink roll 4 with the sections 18, 19, so that the bearing pin 8 is already slit 2
9 so that the ink roll can be captured by the shell member 3 and removed from the holding member.

When the ink roll receiver is subsequently rotated,
The shell 2 is inserted between the arms 27 and 28 with the ink roll 4 located in the shell, and the bearing pin 8 is inserted into the corresponding slot 29 in the arms 27,28. Shell member 2
The outer surfaces 23 and 24 of the arm 2 extend parallel to each other at a distance corresponding to the width of the ink roll 4, so that when a new ink roll is inserted, the arm 2
No spreading action occurs at 7 and 28, so that the aforementioned short bearing pin 8 reliably reaches engagement with the slot 29. Subsequently, in order to release the receiving device 1 from the ink roll 4, the receiving device 1 is rotated slightly about the axis of the ink roll 4;
This makes it possible for the receiving device 1 to be pulled away from the ink roll 4 in a direction different from the direction of insertion into the slot 29. This slit 29 is provided with a small constriction so that the slit 29
9 receives the bearing pin 8 with a snap action;
It would also be possible to retain the bearing pin against light pull-off forces. In this case, it is possible to remove the ink roll receiving device 1 from the ink roll 4 in the same direction as the insertion of the bearing pin 8 into the slot 29.

According to the above-mentioned example of use of the ink roll receiving device 1, at a certain point in time, i.e. after the used ink roll 4 has been removed, an ink roll is located in both shell parts 2 and 3. It turns out. Therefore, it is possible that the ink roll 4 that has just been removed from the shell member 3 is inserted again into the holding member having the arms 27 and 28 by mistake, instead of the new ink roll 4 that is inside the shell member 2. Probably. To avoid this, the outer surfaces 25 and 26 of the shell member 3 are
is constructed so that when the shell member 3 enters between the arms 27 and 28, the arms are expanded. Due to this expansion action, the slit 2
The bearing pin 8 cannot be engaged with the bearing pin 9, so that it is not possible to insert the inking roller 4 in the shell part 3 into the printing machine. Only the new ink roll 4 in the shell 2 can then be inserted, since the arms 27 and 28 are not expanded when the shell 2 is inserted, so that the bearing pin 8 is brought into engagement with the slot 28. Because you will get it.

Since used ink rolls cannot always be easily distinguished from new ink rolls,
The width of the web 9 of the ink roll receiving device 1 is designed in the manner already described so that it narrows from the side of the shell 3 towards the shell 2. web 9
This shape makes it possible to visually reliably identify two ink rolls 4 held together by the web 9 at a certain stage of the exchange process. The purpose of making the inner diameter 11 of the inner surface of the legs 12 and 13 larger than the diameter of the ink carrier 5 of the ink roller 4 is to
This is to prevent the ink from coming into contact with the surface of the ink carrier 5. When such contact is made, the ink carrier 5
This is disadvantageous because a constant pressure is exerted on the ink carrier 5, which causes the ink to be forced out at the contact point in question, resulting in uneven ink distribution within the ink carrier 5.

By using the above-described ink roll receiving device 1 according to the present invention, it is possible to replace a used ink roll with a new ink roll in a printing machine without having to directly touch the ink roll with a finger. .
