Abstract

An apparatus for tool plate positioning for a flat press has upper and lower tool receiving plates (11, 21), and upper and lower mounting plates (10, 20) associated with the upper and lower tool receiving plates. The tool receiving plate (11, 21) can be pushed in against the mounting plate (10, 20), wherein the depth of the push-in position for the tool receiving plate (11, 21) in the push-in direction (7) is given by a respective separate stop (32, 33) which fixes the push-in position by assembling the upper mounting plate with respect to the lower mounting plate (10, 20). For this purpose, a first and a second locking actuator (12, 12', 22) are provided, by means of which the tool receiving plate (11, 21) can be tensioned at a mounting plate (10, 20) associated with the tool receiving plate.

Description

Apparatus for positioning tool plate of flat press

Technical Field

The invention relates to a device for positioning a tool plate of a flat stamping machine.

Background

A tool for a camber stamping and embossing machine is known from EP 2 351 A1.

GB 2,337,224 uses lateral tensioning means for securing the tool to the substrate.

EP2 279 835 shows another device so that the tools for the camber stamping and embossing machine can be replaced more easily.

EP 2 087 972 A1 shows an apparatus for stamping arched materials made of paper, cardboard or the like, said apparatus having: an upper platen and a lower platen; a first male die comprising a stamping and/or groove tool, the male die being connected to an upper platen; and a second female die, which comprises a plate carrying the lower die, which is held in a frame, wherein the lower die is connected, in particular screwed, to the plate, the frame being connected to the lower platen by means of a clamping mechanism, and the frame being horizontally adjustable with the plate carrying the lower die relative to the lower platen by means of an adjusting device.

In summary, the devices for accommodating stamping and punching tools for processing or refining different printed materials, such as paper, cardboard, film or tube laminates, generally have two simple flat plates, to which the stamping and punching tools are fastened. Here, there are an upper tool accommodating plate and a lower tool accommodating plate. Typically, a female mould is mounted in the upper part, said female mould being particularly heated for embossing, and a male mould is mounted in the lower part. But this can also be arranged inversely in the machine.

The upper and lower plates must be precisely oriented with respect to each other in the machine. In the prior art according to the applicant, the upper and lower plates are connected to each other by means of two guide pins and two sleeves, so that the positions are oriented relative to each other. This has the following disadvantages: the two plates must be removed from the machine all the time. Because trimming is performed only on the lower plate, in conventional solutions the entire cassette must be taken out and the upper plate removed each time; or if necessary the cassette must be rotated and the lower plate removed and placed on the side work surface.

Another disadvantage is that in the case of transversely running embossed film, the embossed film must be cut to remove the cassette.

Disclosure of Invention

Based on this prior art, the object of the present invention is to reduce the set-up time for a stamping or embossing machine, for example when changing the score or impression to be produced or when changing from one method type to another, so that the productivity of the stamping or embossing machine mentioned at the outset is increased.

According to the invention, the object is achieved by: in the stamping and embossing machine, additional second plates, also called mounting plates, are mounted on each side of the machine. One mounting plate is disposed above the upper receiving plate and the other mounting plate is disposed below the lower receiving plate. The upper mounting plate and the lower mounting plate are connected with the guide pin and the sleeve. The respective receiving plate is oriented at a defined stop on the mounting plate.

In other words, according to the invention, the object is achieved by: in the stamping and embossing machine, an additional floating-mounted unit is inserted between the two pressure plates (Tiegel), i.e. between the embossing head and the embossing table, which is pressed from below onto the unit of the mounting plate and the tool receiving plate. The units are formed by an upper plate and a lower plate, respectively, called mounting plates, which plates can be implemented entirely or also in a covering manner only as part of the working surface. The mounting plates may also be mounting frames, respectively, so that the mounting frames are not complete, since the basic function is the fastening of the floating unit. A heating unit may then be mounted into such a mounting frame, which heating unit then acts substantially on the tool receiving plate.

In other words, the device for tool plate positioning of a flat press has upper and lower tool receiving plates and associated upper and lower mounting plates which are connected to each other and oriented by two guide bars and sleeves. The tool receiving plate can be pushed in against the mounting plate, wherein the depth of the push-in position for the tool receiving plate in the push-in direction is specified by a corresponding individual stop. In this case, a further stop can be provided at the rear edge of the mounting plate, wherein the user notices the end position when the respective tool receiving plate is pushed to the depth. However, technically, the position of each tool receiving plate is only specified by the separate laterally oriented stop only when the locking actuator is activated. The required positioning of the tool receiving plates relative to one another for the process is defined by guide posts or guide posts and guide sleeves, which serve either directly as stops or are connected to the respective individual stops via a mounting plate. The specific orientation is carried out here by mechanical locking by means of an actuator or manually. For this purpose, a first and a second locking actuator can be provided, by means of which the tool receiving plate can be tensioned in the position defined by the stop at the mounting plate associated therewith. The mounting plates are arranged at a distance from each other and are pushed further towards each other during the embossing process. The continuous pin ensures that the positioning of the embossing tool on the tool receiving plate does not change even during the movement cycle. At least two stops are present at the upper and lower parts, which are either directly formed by means of the guide post/rod and the sleeve, or are mounted separately on the mounting plate, or are connected directly to the guide post or sleeve as separate stops. Thus, each tool receiving plate has at least two stop points which are matched to the stops provided for orientation.

In this case, the upper mounting plate is advantageously pushed together relative to the lower mounting plate by a guide sleeve, which can advantageously serve at the same time as a stop, which leads to a higher degree of precision. Two sleeves with one flange each can be provided, which are placed into corresponding holes in the mounting plate. The containment plate is then pneumatically oriented and clamped to the mounting plate. For this purpose, a locking actuator is provided.

As a result, a separate removal can be achieved, which results in a shorter adjustment time, since the trimming can be carried out directly at the exchange station. If the upper plate has to be pulled out for cleaning the tool, a faster accessibility to the tool is likewise ensured. Furthermore, in the case of continuous films, cutting of the film is no longer necessary. The film may be pushed to one side so that the path for the receiving plate is hollow out of the machine.

During the stamping or embossing process, it is now necessary to move the tool. This is now no longer achieved by means of the receiving plate, but rather by means of the mounting plate. The mounting plate is floatingly supported in the machine and is connected to the motor via a spindle. Instead of a spindle, one or more electrically or manually driven adjustment mechanisms may be connected to the remaining machine structure. Lateral movement of the units of mounting plate and tool receiving plate for embossing can now be performed by means of operation on the HMI. Guiding one of the mounting plates in the transverse direction ensures that the mounting plate is pushed precisely sideways for the stamping process by means of only one motor. The floating support should in particular allow a movement in the horizontal direction, for example in the range of plus/minus 5mm, and should likewise allow an angular rotation and an angular adjustment.

The stop for the push-in depth is formed by a pair of recesses at one side of the tool receiving plate and a complementary connecting pin section for fixing the two mounting plates relative to each other. The connecting pin section is also understood to mean, in particular, a guide sleeve through which the connecting pin then protrudes.

In order to orient the mounting plate, locking means are required which lock the mounting plate on the guide post and the guide sleeve or a stop provided for this purpose.

Advantageously, a slide guide embodied as a single-sided dovetail guide is provided on the opposite side of the tool receiving plate from the one side, the complementary guide on the mounting plate side of the slide guide being braced by the first locking actuator. In other words, a tensioning force acting in the direction of arrow 6 transversely to the insertion direction of fig. 6 is applied to the tool receiving plate.

Alternatively, the locking mechanism may also be provided on the side of the guide post and guide sleeve, in which the plate is oriented by one or more actuators at a stop provided for this purpose. The further second locking actuators arranged on the left and right in the push-in direction ensure the adjustment of the first locking actuator and take into account the weight and size of the tool receiving plate.

In a further advantageous embodiment, the lower mounting plate is essentially realized as a side frame carrying the elements essential to the invention and locking the lower tool receiving plate relative to the guide mechanism (sleeve/pin), but in other cases the lower tool receiving plate may be placed on the embossing table. It is then also advantageous to lock the lower tool receiving plate itself to the embossing table during embossing by means of a further locking actuator, i.e. to hold the floating support only for the adjustment process (displacement and offset).

For this purpose, with reference to the other embodiments mentioned above for the first embodiment, the second locking actuator can be designed to be adapted to the side associated with the recess in such a way that it tightens the pressing device pressed onto the side.

The upper or lower mounting plate may be provided with a heating plate or be designed in one piece with the heating plate, so that corresponding working steps may be carried out.

The unit formed by the upper and lower mounting plates, which are connected via pins, has connection elements, for example spring plates, by means of which the floating support of the unit is formed in the stamping or embossing machine.

Further embodiments are specified in the dependent claims.

In EP 2 087 972 A1, the inserted plate can be moved in a corresponding frame. It is not possible, however, to form a unit from an upper tool receiving plate and a lower tool receiving plate, in which the upper tool receiving plate and the lower tool receiving plate are connected to form a unit after being pushed in up to a predefined stop, and then move and/or rotate as such a unit in a plane. By unlocking the upper and lower tool receiving plates relative to each other, each individual tool receiving plate can be removed from the machine individually, replaced or serviced, and the tool receiving plate or another tool receiving plate can be pushed in again without the need to cancel the existing positioning of the movement of the tool receiving plates in the method approach, as that positioning is maintained via another maintained positioning of the mounting plate.

Detailed Description

Fig. 1 shows an exploded perspective view of a receiving device of an embossing and stamping tool according to an embodiment of the invention, and fig. 2 shows an enlarged detail of fig. 1. Like features are provided with like reference numerals throughout the drawings.

In the housing apparatus according to the present invention, the upper mounting plate 10 and the lower mounting plate 20 are used. In the illustration of fig. 1, the tool receiving plates 11 and 21 are pushed together partially with the mounting plate 20. For this purpose, the lower tool receiving plate 21 is placed on the upper side of the lower mounting plate 20 and is then pushed together, wherein on the opposite side of the lower tool receiving plate 21 opposite edge surfaces 34 slide under the respective sides of the two holding-down devices 35. The tool receiving plate 21 slides with its left front edge 36 and its right tapered end edge 14 between the inwardly directed borders of the actuator 22 and on the opposite side against the guide rail 15 complementary to the tapered end edge 14 up to two depth stops, not shown in fig. 1, which are inserted into the holes 17 in the vicinity of the rear end of the lower mounting plate 20 and against which the recesses 18 are guided. The front flange inside the edge of the lower guide sleeve 32 is thus in the region of the positioning recess 33. The introduction direction itself is provided with reference numeral 7.

The method approach is similar for the upper mounting plate 10 and the upper tool receiving plate 11, except that in the embodiment shown here, a heating plate 5 is provided below the upper mounting plate 10. The heating plate is here considered as a unit together with the upper mounting plate 10. The heating plate may be omitted in other applications.

In this case, fig. 1 shows the perforated underside of the upper tool receiving plate 11, which is pushed from below onto the upside-down upper mounting plate 10 with the heating plate 5, with corresponding pressing devices being provided on the opposite sides of the locking cylinders 12, 12' of the upper tool receiving plate 11/heating plate 5.

The positioning recess at the end of the lower tool receiving plate 11 to be pushed in, which has a rounded shape corresponding to the outer diameter of the flange 32 of the lower guide sleeve 31 through which the guide pin 13 is inserted, is designated by reference numeral 33. A corresponding second positioning recess 33 is provided on the same side of the tool receiving plate 11, which is shown on the left, and is associated with a second flange of the guide sleeve 31 of the lower mounting plate 20, which is likewise provided on said side.

At the upper tool receiving plate 11, two further positioning recesses 43 are correspondingly provided on the same side, which is shown to the left here.

On the opposite side of the upper tool receiving plate 11, shown to the right here, the right-hand edge 14 tapers in order to be held relative to the guide attachment 15 and the upper mounting plate 10. The guide attachment 15, which can be moved by the locking cylinder 12', also serves here as a guide rail. Thereby, the position of the tool receiving plates 11 and 21 relative to the insertion direction 7 is preset by the stop pairs 17/18. The tool receiving plate 11 is fixed to the upper mounting plate 10 by pushing a guiding attachment 15 connected in a controlled manner to the locking cylinder 12' in the direction of arrow 6.

In the case of a continuous film, the continuous film is located between the two tool receiving plates 11 and 21 in the direction of the arrow 6 or 7. In other words, the continuous film may be processed not only in the longitudinal direction but also in the transverse direction (corresponding to the arrow direction).

Fig. 3 shows an exploded perspective view of a receiving device of the stamping and punching tool as in fig. 1, in which case the tool receiving plates 11 and 21 are pushed in, fig. 4 shows an enlarged detail of fig. 3. Here, at least after activation of the locking cylinder 22', the position recess 33 impinges on the outer edge of the ring 32, so that the lower tool receiving plate 21 is held in and at the lower mounting plate 20. Other relationships are then described in connection with fig. 5.

Thereby, in fig. 3, mounting plates 10 and 20 and tool receiving plates 11 and 21 are shown to be pushed together for use. After activation of the locking cylinders 12, 12', 22', the upper mounting plate 10 can no longer be pushed with respect to the upper tool receiving plate 11 and the lower mounting plate 20 can no longer be pushed with respect to the lower tool receiving plate 21. The upper mounting plate and the lower mounting plate form a machining unit for embossing. The unit is pushed for embossing by means of an electric side adjustment in the direction of arrow 7.

Fig. 5 shows a perspective view of the holding device of fig. 1 in the assembled state, i.e. the state in which the continuous film to be embossed passes in the direction 7, and fig. 6 shows a further perspective view of the holding device of fig. 5. Also included therein is fig. 7, which shows a perspective view of the lower mounting plate 20 with an associated lower tool receiving plate 21. The upper tool receiving plate 11 is advanced at the upper mounting plate 10, wherein a hollow positioning sleeve 16 impinges from below onto the upper mounting plate 10 and is fastened thereto. The pin 13 extends in the hollow positioning sleeve 16, said pin protruding underneath through the guide sleeve 26. The edge of the guide sleeve 26 serves as a stop for the positioning recess 33. From above the upper mounting plate 10 is provided with: a bolt plate 27 into which bolts are screwed; here, three guide sleeve bolts 28 ending in the cylinder wall of the positioning sleeve 16 at an angle of 120 degrees to each other and a central guide pin bolt 29 ending in the guide pin 13. Embossing can also take place in the direction 6.

The device has four locking cylinders 12, 12' for the upper tool receiving plate 11. With respect to the four locking cylinders, four locking cylinders 22, 22' for the lower tool receiving plate 21 are likewise provided.

The following directions of movement are indicated with reference number 6: in the direction of movement, the tool receiving plate 11 is passed through the upper locking cylinder 12' and the lower tool receiving plate 21 is tensioned by the lower locking cylinder 22' via the tapered side edges 14 or the pressing means 35' in the direction of arrow 6 in order to be locked for the stamping or embossing movement. In contrast, the locking cylinders 12 and 22 act on the pressing devices 35 on the opposite side.

The unit formed by the upper and lower mounting plates 10 and 20, which are connected via pins 13 in sleeves 26 and 16, has connecting elements 19, by means of which a floating support of the unit is formed in the stamping or embossing machine. The illustrated connecting element is a lateral spring 19 which engages into a complementary element of the machine and in this case floatingly supports the unit formed by the mounting plates 10 and 20 etc.

As is clearly evident from fig. 7, the locking cylinder 12' for the tool receiving plate 21 likewise has an upwardly closed bevel, so that the tool receiving plate 21 is pushed in the direction of the arrow 6 on the one hand and the tool receiving plate 21 is blocked by the upwardly closed bevel in the direction of said arrow and perpendicular to the plane of the mounting plate 20. As in the tool receiving plate 11, a pressing device 35 is provided on the opposite side.

In summary, the upper tool receiving plate 11 is pushed in the direction 7 against the mounting plate 10, by means of the lateral locking cylinder 12', the tool receiving plate 11 is pressed laterally against the shank (Schaft) of the guide pin 13 and is then held in this position in order to be stopped there against the recess 43. Subsequently, with the lateral locking cylinder 12 activated, the tool receiving plate 11 becomes a unit with the upper mounting plate 10.

In a similar manner, on the other side, the lower tool receiving plate 21 is pressed laterally against the shank of the guide sleeve 31 by means of the lateral locking cylinder 22', and is then held in said position in order to be stopped there against the recess 33. Subsequently, with the lateral locking cylinder 22 activated, the tool receiving plate 21 becomes a unit with the lower mounting plate 20.

By connecting the two units thus created via the pins 13 engaged into the sleeve 31, a tool unit is formed in which the tool receiving plates 11 and 21 are fixedly positioned relative to each other, while the tool unit itself is supported in a floating manner on the embossing table 100 (not shown in fig. 1 to 8) via springs 19 provided on both sides.

Fig. 8 shows an exploded perspective view of a receiving device for stamping and punching tools according to a further embodiment of the invention, with two tool receiving plates 11, 21 and two mounting plates 10, 20, one tool receiving plate 11 being external and not being pushed in. For this purpose, fig. 9 shows an enlarged detail of fig. 8. Like reference numerals refer to like features.

According to the second embodiment, the two tool receiving plates 11, 21 are again pushed into the press in the direction of the arrow 7 as in the first embodiment. However, the two guide posts 13 and guide sleeves 31 are now arranged behind in the insertion direction, at which the mounting plates 10 and 20 are oriented and firmly connected to one another. Advantageously, said guide posts 13 and guide sleeves 31 are provided at the corners of the plates 11 and 21.

By means of two respective pneumatic cylinders 112 or 122, the tool receiving plate 11 or 21 is locked with the mounting plate 10 or 20 and thus at the guide post 13 or the guide sleeve 31.

Two upper pneumatic cylinders 112 are provided near the end edges at the upper mounting plate 10 between the guide pins 13 placed in the corresponding holes. For this purpose, at the upper tool receiving plate 11, a C-shaped hook 144 is provided at the end edge in the introduction direction 7 in order to co-act with the pneumatic cylinder 112.

The upper tool receiving plate 11 is locked at the upper mounting plate 10 by four further pneumatic cylinders 12. For this purpose, the side edges 114 of the tool receiving plate 11 are designed to be surrounded by the holders of the pneumatic cylinder 12 and to be pressed against the underside of the mounting plate 10 from below. In contrast to the embodiment of fig. 1 and as an alternative to the embodiment of fig. 1, the upper tool receiving plate 11 is pushed in the direction 7 by means of corresponding lateral guides until the hooks 144 come to rest on the front edge and then lock there forward and four times laterally with the pneumatic cylinder 12. In a simpler embodiment it is also possible to omit two cylinders 112 closer to the pneumatic cylinder 12, so that again there are only four locking cylinders. However, in the case of the larger dimension in the direction 6, i.e. the width of the rail to be processed, two pneumatic cylinders on each side are a meaningful holding means.

The lower tool receiving plate 21 is first locked to the guide sleeve 31 by only two pneumatic cylinders 122 at the lower mounting plate 20. The pneumatic cylinder 122 is arranged between the sleeves 13 at the end edge of the lower mounting plate 20 in the direction of insertion 7. By means of the described embodiment of the second embodiment, which has been described here until now, the same tool unit as in the first embodiment is thereby achieved. When the upper and lower mounting plates 10 and 20 are guided together with the tool receiving plates 11 and 21 locked therein, a unit is realized which is arranged floatingly on the embossing table 100 and which can then be pushed on the embossing table 100 by other actuators not shown here by a few millimeters and rotated, if necessary, by a predetermined angle in order to achieve the advantages of the invention. In the second embodiment, the upper tool receiving plate 11 can thus also be pulled out of the unit separately by disengaging the pneumatic cylinder 112 and the cylinder 12, for which purpose in particular a handle 44 is provided. And by disengaging the lower pneumatic cylinders 122 and 122', the same applies to the second tool receiving plate 21.

But now a second embodiment will be further described. Advantageously, the lower mounting plate 20 is as light as possible. Finally, the lower mounting plate may be replaced by a frame adjoining the embossing table 100, as the frame is shown in fig. 9 ff. The lower mounting plate 20 then still achieves with its sleeve 31 that the lower tool receiving plate 21 is stopped and fastened and fixed relative to the frame 20 by means of the lower pneumatic cylinder 122, but is lighter and the underside of the lower tool receiving plate 21 is placed directly on the embossing table. Since the width of the material to be embossed by means of the embodiment may be large in size, it is advantageous to fix the floating unit relative to the embossing table 100 in the embossing itself.

The lower tool receiving plate 21 is additionally locked at the embossing station 100 (also shown in dashed lines) by four further pneumatic cylinders 122' (shown in dashed lines in fig. 9). However, the lock must be disengaged to move or misalign the tool receiving plates 11, 21 laterally relative to the platen because the tool receiving plates are not connected to the lower mounting plate 20. In the case of a lower table speed, the additional locking with the pneumatic cylinder 122' may also be dispensed with.

Fig. 10 shows an exploded perspective view of the holding device of the stamping and punching tool as in fig. 8, with the tool holding plates 11, 21 pushed in and locked to one another, and fig. 11 shows an enlarged detail of fig. 10 before locking the upper mounting plate/tool plate unit 10/11. The upper tool receiving plate 11 collides with the positioning sleeve 16 of the guide pin 13 in the push-in direction with the positioning notch 143. The lower tool receiving plate 21 collides with the guide sleeve 31 in the push-in direction with the positioning recess 133.

FIG. 12 shows a perspective view of a receiving device of the stamping and punching tool of FIG. 8, without the advanced tooling plate; and fig. 13 shows an enlarged detail of fig. 10.

The entire unit is floatingly connected to the imprint head and the imprint table 100 acting from below. Here, the platen moves. The entire unit in the machine can be moved laterally with respect to the track travel direction 6 of the printing material or can be offset at an angle with respect to the track travel direction by two adjustment mechanisms, for example a spindle as in the first embodiment or other actuators connected to the upper mounting plate 10. Both adjustments may be implemented at the HMI.

Unlike the first embodiment, the two tool receiving plates 11, 21 in the second embodiment do not have to be moved laterally relative to the mounting plate (in the first embodiment by the inclined side edges 14 and the columns 12') moving in the direction 6, since the guide columns/pins 13 are arranged behind, wherein "behind" means at the rear edge in the pushing-in direction 7 of the tool receiving plates 11 and 21 and thus transversely to the direction of movement 6. Furthermore, the lower mounting plate 20 is not embodied entirely for cost reasons as well as for precision reasons; which is a frame at which the mentioned components are arranged.
