Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pressure zone for an edge gluing or mail forming machine having a number of pressure roller sets which can be brought into their working position separately from each other.

Outsourcing production to edge-gluing or post-forming machines is only possible if the integrated machinery required for processing each workpiece can be brought to its working position without special downtime. It is economically feasible.

In capping, milling or other integrated machines, the above problem is solved by introducing all the integrated machines required for the processing into the processing line in series. Therefore, when switching to another workpiece, simply transfer and move each time.

Alternatively, in some cases only minor adjustments are required. Therefore, large downtimes can be avoided.

However, the pressure area is a problem in edge sticking or mail forming machines. The above-mentioned pressure zone must always be immediately behind the sticking point in the direction of passage of the work piece, so that immediately after the workpiece is stuck, the edge pressurization must be carried out through the pressure zone. In this case, it is impossible to arrange the various pressurized areas in a front-to-back relationship with respect to the various workpieces, as is the case when the workpieces pass through the machine during contract manufacturing. It is.

Therefore, in order to reduce the downtime when transferring from one pressure area to another, pressure roller sets have already been developed which are brought to the working location as a unit on demand. That is, it is true that if this is done, the downtime for changing the pressurized area will be slightly reduced. However, sufficient reduction of downtime and automation of this process
Even with this measure, it has not become possible.

According to the invention, this object is solved in that the pressure roller sets are fixed on a joint rotating device and can be individually brought into actuating position verbally.

According to a feature of the invention, the pressure roller set required for the respective processing is placed in the rotating device as a pre-prepared unit, which is immediately ready for operation when the first pressure is applied to the pressure zone. so that, when required, the unit to be machined in each case can be brought into its working position at the edge of the workpiece by a simple rocking or pivoting movement. Therefore, manual replacement, as was previously required for replacing certain areas. There is no need to replace the pressure roller set.

In an advantageous embodiment of the invention, the rotating device is configured as a drum-shaped, rotating cross-shaped or rotating star-shaped device, with parallel axes running parallel to the direction of passage of the workpiece. has been done. In one such device, a pre-prepared set of pressure rollers is moved to the operating position by simply oscillating the rotary device by a certain degree by means of an easily automated device. brought to. Based on this type of device, pressure roller sets with a large number of front plates are arranged around the drum device, rotating cross device or rotating star device, and therefore it is possible to perform an extremely wide variety of work. becomes.

Furthermore, in an advantageous implementation of the invention, the rotating device is provided with a central shaft, which is floatingly supported on the stator. In each case, the central axis serves as a support arm which can provide extremely stable dimensions without any technical difficulty. Since it is floatingly supported as described above, it is only necessary to place the stator on one side of the pressurized area. It can thus be ensured that its free end is pressed relatively tightly against the sticking point.

In order to obtain as many adjustment possibilities as possible, the stator is equipped with a cross-slide device that allows the axis to be displaced parallel to the axis in a plane perpendicular to the direction of workpiece passage. It is possible to set up According to this method, the center shaft, and thus the pressure roller set, can be moved back and forth, and can also be pulled up and taken down.

In an advantageous embodiment, rods parallel to the axis are fixed around the periphery of the carrier, spaced apart from each other on the axis.
A disk-shaped, cross-shaped or star-shaped carrier is arranged on which a set of pressure rollers is fixed in a displaceable manner. Shading in this manner not only makes one structure relatively simple, but also allows individual pressure rollers to be arranged in multiple stages. Thus, for example, for a certain edge shape, pressure rollers can be provided on a number of bars arranged next to each other, so that several rows of roller sets act on the edge. can. Despite these various possibilities, the overall outlook for this arrangement is relatively good.

For rotating the shaft and/or operating the cruciform slide, a manually operable adjusting shaft, a hydraulic or pneumatically controlled cylinder, or an electrically controlled motor may be provided. When applying this to an automatic machining line, the rotation of the shaft and/or the operation of the cross-shaped slide can be controlled by a program as necessary, eliminating the need for manual switching. Become.

In one advantageously implemented embodiment of the invention, said bale is fixed such that it can be displaced around the carrier. According to this, there are many possibilities for the arrangement of the pressure rollers, so that even the most complex pressure problems can be solved.

In order to achieve sufficient fixation, it is necessary to make a rough oscillation toward the respective operating position, then to be able to bring it to the correct position by means of a restraining device, and to be able to fix it in this position. is appropriate. According to the above-mentioned method, it is therefore possible to use all kinds of, and therefore economically advantageous, drive devices for oscillating the rotary device.

This is because fine adjustments can be made by means of an unrelated device. Advantageously, the restraining device provided for said fine adjustment has a syringe-actuated ram which can enter into a sleeve fixed to the one-turn device in a position dependent on the respective operating point. do. Such an arrangement is not only simple to manufacture, but also more reliable and reliable in operation.

In the above-mentioned restraint devices, it is fixed directly to a disc-shaped, cross-shaped or star-shaped carrier.

An advantageous construction is obtained by providing a corresponding number of sleeves in two locations, which are fixed around the circumference of the tubular sleeve. According to this method, since there is no need to use a transmission joint that includes play, extremely accurate restraint can be performed with a simple method.

In an advantageous embodiment of the invention, the above-mentioned push rod and/or sleeve are configured conically,
At the same time, if it is fixed without play, the rough rocking will cause
Fine tuning is achieved. That is, with this conical configuration, each sleeve, which is arranged with different protruding rods and shafts for the purpose of swinging the arm, can be swung to its correct position by the entry of the protruding rod. , and in the completely inserted state, is immovably fixed in this position by the protruding rod.

Next, for a more detailed explanation and better understanding of the present invention, embodiments of the present invention will be described with reference to the drawings.

The pressure area for the edge sticking or mail forming machine shown in the drawings has a vertically oriented cradle 1 which, on its negative side, can move vertically up and down against the cradle 1. A dovetail guide for the sliding rack 3 is provided.

The sliding rack 3 furthermore has a dovetail guide 4, in which a sliding rack 5 is arranged so that it can be moved back and forth in the horizontal direction. Both sliding racks 3 and 5 constitute a cross-shaped sliding rack device.

A bearing 6 that supports the central shaft 7 is attached to the sliding rack 5. The bearing 6 for this shaft 7 is shown in FIG.
It is shown enlarged with a partial cross section.

In this case, two cruciform carriers 8, 9 arranged at a distance are fixed on the shaft 7, which is supported in a floating manner on a bearing 6, the shape of which is shown in FIG. ing. said cruciform carrier 8, which is arranged on the axis 7 in exact alignment;

The rods 10, 11, 14 and 15 each carry a number of pressure rollers 16, each consisting of a holding device 17 fixed to the rod and a roller body 18. There is.

In the illustrated embodiment (see FIG. 5), two rows of pressure rows 218 are combined into one pressure rope set 19.

As is clear from FIGS. 1 to 6, a holding device 20 is also arranged on the cruciform carriers 8 and 9, outside the rods 10 to 15 and parallel to the axis 7. This holding device 20 carries a number of trochanters 21 arranged exactly next to each other, and
These also constitute one pressure roller set as a whole.

The shaft 7 has cruciform carriers 8, 9 . Together with the rods 10 to 15 and the holding device 20, it constitutes a rotating device.

In this embodiment, the rods 12, 13 are no longer pressurized.
It does not carry any rollers (see FIG. 3), so the rotating device shown has in total only six sets of pressure rollers, each offset by 90 DEG with respect to one another.

As is clear from FIG. 4, a tubular sheath 22 is fixed to the cruciform carrier 8 at its free end, carrying a ring 23, which is separated by an angle from the sleeve 22.
It has 4. The protruding rod 25 is inserted into the sleeve 24.

A control axis that can be moved together with the robot.

There is also no control cylinder or control motor present.

Now, when processing workpieces on a contract basis, certain types of workpieces are glued to the edges or when inserted into a mail-forming machine, markings and other marks from the machine are removed. The students are made to understand the identification items in this way. The workpiece is then fed at the sticking point (not shown) and then by a first pressure roller (not shown).

Pressure is applied to the work piece. Following this, the workpiece (indicated by dashed lines in the drawing) enters the working range of this processing area. In the illustrated embodiment, a pressure roller set consisting of a pressure roller 21 acts on the protrusion of the workpiece.

Guidance of the processing area to the respective processing roller set is as follows:
The gluing of the edges takes place already upon introduction into the mail forming machine. The entire rotating device is displaced by the sliding rack device and the central shaft is subsequently rotated until the respective set of pressure rollers lies in the operating position. In this case, the rotation device is fixed after the pivoting process has been completed by the insertion of the protrusion 25 into the sleeve 24 (see FIG. 4). Thereafter, the pressure roller set is brought to a proper position opposite to the workpiece by the sliding rack device, and further moved in the horizontal direction to reach the desired location.
