Abstract

The device for positioning the tool plates of a flat stamping press has an upper tool receiving plate (11) and a lower tool receiving plate (21) and an upper mounting plate (10) and a lower mounting plate (20) associated with the upper and lower tool receiving plates. The tool receiving plates (11, 21) can be pushed in against the mounting plates (10, 20), wherein the depth of the push-in position for the tool receiving plates (11, 21) in the push-in direction (7) is given by corresponding individual stops (32, 33) which fix the push-in position by assembling the upper mounting plate relative to the lower mounting plate (10, 20). For this purpose, first and second locking actuators (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

Device for positioning a tool plate of a flat embossing press

Technical Field

The invention relates to a device for positioning a tool plate of a flat-bed stamping press.

Background

A tool for a camber punching and stamping machine is known from EP 2351634 a 1.

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

EP 2279835 shows another device so that the tools for the arching press and stamping machine can be exchanged more easily.

EP 2087972 a1 shows a device for punching arched material consisting of paper, cardboard or the like, said device having: an upper platen and a lower platen; the first male die comprises a stamping and/or groove cutter, and is connected with the upper pressure plate; and a second female mold, which comprises a plate that is held in a frame and that carries the lower mold, wherein the lower mold is connected, in particular screwed, to the plate, wherein the frame is connected to the lower platen by means of a clamping mechanism, and wherein the frame together with the plate that carries the lower mold is horizontally adjustable relative to the lower platen by means of an adjusting device.

In summary, the devices for accommodating embossing and punching tools for processing or refining different printed materials, such as paper, cardboard, film or tube laminates, usually have two simple flat plates to which the embossing and punching tools are fastened. Here, there are an upper tool receiving plate and a lower tool receiving plate. Usually, a female mold is mounted on the upper part, said female mold being particularly heated for embossing, and a male mold is mounted on the lower part. However, this can also be reversed 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 as to orient the positions with respect to each other. This has the following disadvantages: both plates must always be removed from the machine together. Since trimming is only performed on the lower plate, in conventional solutions the whole box has to 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 a nearby work surface.

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

Disclosure of Invention

Based on the prior art, the object of the invention is to reduce the setup time for stamping or embossing machines, for example when changing the scores or impressions to be produced or when changing from one method type to another, in order to increase the productivity of the stamping and embossing machines mentioned at the outset.

According to the invention, said object is achieved by: within the stamping and embossing machine, additional second plates, also referred to as mounting plates, are mounted on each side of the machine. One mounting plate is arranged above the upper accommodating plate, and the other mounting plate is arranged below the lower accommodating 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 stamping and embossing machines, an additional floating bearing unit is inserted between two pressure plates (Tiegel), i.e. between the embossing head and the embossing table pressing from below on the mounting plate and the unit of the tool receiving plate. The unit is formed by an upper and a lower plate, respectively, called mounting plate, which plates can be embodied over the entire surface or can be embodied in a covering manner only as a part of the working surface. The mounting plate can also be a mounting frame, respectively, which is thus not the entire surface, since the essential function is the fastening of the floating unit. A heating unit can then be installed in such a mounting frame, which heating unit then acts substantially on the tool receiving plate.

In other words, the device for the positioning of a tool plate of a flat bed stamping press has an upper and a lower tool receiving plate and an upper and a lower mounting plate associated therewith, which are connected and oriented to each other by means of two guide rods 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 defined by a corresponding separate 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 being reached when the respective tool receiving plate is pushed into the depth. Technically, however, the position of each tool receiving plate is only defined by the individual 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 rods and guide sleeves which either serve directly as stops or are connected via a mounting plate with corresponding separate stops. The defined orientation is performed 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. The continuous pins ensure that the position of the stamping tool on the tool receiving plate does not change even in the movement cycle. At least two stops are present at the upper and lower part, which are either formed directly by means of the guide post/rod and the sleeve, or are mounted separately on the mounting plate, or are connected directly with the guide post or sleeve as separate stops. Thus, there are at least two stop points per tool receiving plate, which match the stops provided for the orientation.

It is advantageous here that the upper mounting plate is pushed together relative to the lower mounting plate by means of a guide sleeve, which can advantageously simultaneously serve as a stop, which results in a higher accuracy. Two sleeves with one flange each can be provided, which are inserted into corresponding openings 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.

This makes it possible to achieve a separate removal which leads to 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 a continuous film, cutting the film is no longer necessary. The film can be pushed to one side so that the path for accommodating the plate is hollowed out of the machine.

During the working process of stamping or embossing, it is now necessary to move the tool. This is now no longer achieved by means of the receiving plate, but by means of the mounting plate. The mounting plate is floatingly supported in the machine and connected with the motor via a spindle. Instead of a spindle, one or more electrically or manually driven adjustment mechanisms may be connected to the rest of the machine structure. The lateral movement of the unit of mounting plate and tool receiving plate for stamping can now be performed by means of operating on the HMI. Guiding one of the mounting plates in the transverse direction ensures that the mounting plate is pushed laterally precisely by means of only one motor for the embossing process. The floating bearing should in particular allow a movement in the horizontal direction, for example in the range of plus/minus 5 mm, and 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 complementary connecting pin sections for fixing the two mounting plates relative to each other. Here, a connecting pin section is also to be understood to mean, in particular, a guide sleeve through which the connecting pin then projects.

For orienting the mounting plate, a locking device is required which locks the mounting plate at the guide post and the guide sleeve or a stop provided for this purpose.

Advantageously, a sliding guide, which is embodied as a one-sided dovetail guide, is provided on the side of the tool receiving plate opposite the one side, the complementary guide of the sliding guide on the mounting plate side being able to be tensioned by the first locking actuator. In other words, a tensioning force acting in the direction of the arrow 6 transverse to the insertion direction of fig. 6 is applied to the tool receiving plate.

Alternatively, the locking mechanism can also be provided at the side of the guide post and the guide sleeve in which the plate is oriented by one or more actuators at a stop provided for this purpose. The additional second locking actuators arranged to the left and to the right in the insertion direction ensure an 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 realized essentially as a side frame which carries the elements essential to the invention and locks the lower tool receiving plate relative to the guide means (sleeve/pin), but in other cases the lower tool receiving plate can be placed on the stamping station. It is then also advantageous to lock the lower tool receiving plate itself to the stamping station by means of further locking actuators during the stamping process, i.e. to maintain a floating support only for the adjustment process (movement and offset).

For this purpose, with reference to the further embodiments of the first embodiment mentioned above, the second locking actuator can be designed, matched to the side face associated with the recess, such that it tensions the pressing device pressing onto the side face.

The upper or lower mounting plate can be provided with heating plates or be designed in one piece with said heating plates, so that corresponding working steps can be carried out.

The unit, which is formed by an upper mounting plate and a lower mounting plate, which is connected via a pin, has a connecting element, for example a spring plate, by means of which a floating bearing of the unit is formed in a punching or stamping press.

Further embodiments are set forth in the dependent claims.

In EP 2087972 a1, the inserted plates can be moved in the respective frame. However, it is not feasible to form a unit from an upper tool receiving plate and a lower tool receiving plate, in which unit the upper tool receiving plate and the lower tool receiving plate are connected after being pushed in up to a predefined stop into one unit, which then moves and/or rotates in a plane as such a unit. By releasing the locking of 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 maintained, 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 plate in the approach of the method, since the 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 a stamping and punching tool according to an embodiment of the invention, and fig. 2 shows an enlarged detail view of fig. 1. Throughout the drawings, like features are provided with like reference numerals.

In the accommodation 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 partially pushed together 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 then pushed together, wherein on the opposite sides of the lower tool receiving plate 21, the opposite edge faces 34 slide under each of the two pressing devices 35. The tool receiving plate 21 slides with its left front edge 36 and right tapered end edge 14 between the inwardly directed borders of the actuator 22 and on the opposite side against the guide rails 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 near the rear end of the lower mounting plate 20 and against which the recess 18 is 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 approach is similar for the upper mounting plate 10 and the upper tool receiving plate 11, with the difference that in the embodiment shown here, the 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.

Fig. 1 shows the perforated underside of an upper tool receiving plate 11, which is pushed from below onto an upper mounting plate 10, which is arranged upside down and has a heating plate 5, wherein corresponding hold-down devices are arranged on opposite sides of the upper tool receiving plate 11/locking cylinders 12, 12' of the heating plate 5.

The positioning recess at the end of the lower tool receiving plate 11 to be pushed in, which has a radius corresponding to the outer diameter of the flange 32 of the lower guide sleeve 31 through which the guide pin 13 is inserted, is denoted by reference numeral 33. A corresponding second positioning recess 33 is provided on the same side of the tool receiving plate 11, shown on the left here, which second positioning recess 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 arranged on the same side, shown on the left here.

On the opposite side of the upper tool receiving plate 11, which is shown on 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 appendages 15 which can be moved by the locking cylinder 12' also serve here as guide rails. The position of the

tool receiving plates

11 and 21 relative to the insertion direction 7 is thereby predetermined by the pair of stops 17/18. The tool receiving plate 11 is fixed to the upper mounting plate 10 by pushing the guide attachment 15, which is connected in a controlled manner to the locking cylinder 12', in the direction of the arrow 6.

In the case of a continuous film, the latter is located between the two

tool receiving plates

11 and 21 in the direction of the arrows 6 or 7. In other words, the continuous film can 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 the receiving device of the stamping and punching tool according to fig. 1, in which the

tool receiving plates

11 and 21 are pushed in, and fig. 4 shows an enlarged detail of fig. 3. Here, at least after activation of the locking cylinder 22', the position recess 33 strikes against 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 set forth in conjunction with fig. 5.

Thereby, in fig. 3 the mounting

plates

10 and 20 and the

tool receiving plates

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

Fig. 5 shows a perspective view of the receiving device of fig. 1 in the assembled state, i.e. in the state in which the continuous film to be embossed runs in the direction 7, and fig. 6 shows a further perspective view of the receiving device of fig. 5. Also included is fig. 7, which shows a perspective view of the lower mounting plate 20 with the associated lower tool receiving plate 21. The upper tool receiving plate 11 is pushed in at the upper mounting plate 10, wherein the hollow positioning sleeve 16 strikes from below onto the upper mounting plate 10 and is fastened thereto. The pin 13 extends in a hollow positioning sleeve 16, which projects below through a guide sleeve 26. The edge of the guide sleeve 26 serves as a stop for positioning the recess 33. From above the upper mounting plate 10 are provided: a bolt plate 27 into which a bolt is 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. The 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 also provided.

The following directions of movement are indicated with reference numeral 6: in the direction of movement, the upper tool receiving plate 11 is tensioned in the direction of the arrow 6 by the upper locking cylinder 12' and the lower tool receiving plate 21 is tensioned by the lower locking cylinder 22' via the tapered side edge 14 or the pressing device 35' in order to lock for the punching or stamping movement. In contrast, the locking

cylinders

12 and 22 act on the pressing device 35 on the opposite side.

The unit formed by the upper and lower mounting

plates

10 and 20, which is connected in the sleeves 26 and 16 via the pins 13, has a connecting element 19, by means of which a floating bearing of the unit is formed in the punching or stamping press. The connecting element shown is a lateral spring 19 which engages into a complementary element of the machine and in this case floatingly supports the unit made up of the mounting

plates

10 and 20 or the like.

As can be seen clearly in 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 the 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, the tool receiving plate 11 is pressed laterally against the shank (Schaft) of the guide pin 13 by the lateral locking cylinder 12', and is then held in the position in order to stop 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, by means of the lateral locking cylinder 22', the lower tool receiving plate 21 is pressed laterally against the shank of the guide sleeve 31 and is then held in said position in order to be stopped there with the recess 33. Subsequently, with the lateral locking cylinder 22 activated, the tool receiving plate 21 is integrated with the lower mounting plate 20.

By connecting the two units thus created via the pins 13 engaging into the sleeves 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 floatingly supported on the stamping station 100 (not shown in fig. 1 to 8) via the springs 19 arranged on both sides.

Fig. 8 shows a perspective exploded view of a receiving device for embossing and punching tools according to a further embodiment of the invention, with two

tool receiving plates

11, 21 and two mounting

plates

10, 20, wherein one tool receiving plate 11 is on the outside and is not 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 stamping press in the direction of the arrow 7 as in the first embodiment. However, the two guide posts 13 and the guide sleeves 31, at which the mounting

plates

10 and 20 are oriented and firmly connected to one another, are now arranged behind one another in the insertion direction. Advantageously, said guide posts 13 and guide sleeves 31 are provided at the corners of the

plates

11 and 21.

By means of two

pneumatic cylinders

112 or 122 each, 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 that are inserted in the corresponding holes. For this purpose, a C-shaped hook 144 is provided at the upper tool receiving plate 11 at the end edge in the introduction direction 7 in order to interact with the pneumatic cylinder 112.

The upper tool receiving plate 11 is locked at the upper mounting plate 10 by four additional pneumatic cylinders 12. For this purpose, the side edges 114 of the tool receiving plate 11 are designed to be enclosed by the holders of the pneumatic cylinder 12 and to be pressed from below against the underside of the mounting plate 10. 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 a corresponding lateral guide until the hook 144 comes to a stop at the front edge and is then locked there in the forward and four-fold lateral direction with the pneumatic cylinder 12. In a simpler embodiment it is also possible to omit the two cylinders 112 closer to the pneumatic cylinder 12, so as to have again only four locking cylinders. However, in the case of a larger dimension in the direction 6, i.e. the width of the rail to be machined, two pneumatic cylinders on each side are meaningful holding means.

The lower tool receiving plate 21 is first locked to the guide sleeve 31 only by the 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 push-in direction 7. The same tool unit as in the first exemplary embodiment is thereby realized with the aid of the described configuration of the second exemplary embodiment described up to now. When the upper and lower mounting

plates

10 and 20 are guided together with the

tool receiving plates

11 and 21 locked thereto, a unit that is arranged in a floating manner on the stamping table 100 is realized, which unit can then be pushed on the stamping table 100 by a few millimeters by means of further actuators, not shown here, and can be rotated, if necessary, by a predetermined angle, in order to realize the advantages of the invention. In the second exemplary embodiment, therefore, the upper tool receiving plate 11 can also be pulled out of the unit separately by disengaging the pneumatic cylinder 112 and the cylinder 12, for which purpose in particular the handle 44 is provided. And the same applies to the second tool receiving plate 21 by disengaging the lower pneumatic cylinders 122 and 122'.

The second embodiment will now be described further. Advantageously, the lower mounting plate 20 is as light as possible. Finally, the lower mounting plate may be replaced by a frame that abuts the impression station 100, as shown in fig. 9 ff. The lower mounting plate 20 then still with its sleeve 31 effects the stopping and fastening and fixing of the lower tool receiving plate 21 relative to the frame 20 by means of the lower pneumatic cylinder 122, but the lower mounting plate is lighter and the underside of the lower tool receiving plate 21 rests directly on the impression station. Since the dimensions of the width of the material to be imprinted by means of the described embodiment can be large, it is advantageous to fix the floating unit relative to the imprint station 100 in the imprint itself.

The lower tool receiving plate 21 is additionally locked at the impression station 100 (also shown in dashed lines) by four further pneumatic cylinders 122' (shown in dashed lines in fig. 9). However, the locking must be disengaged to allow the

tool receiving plates

11, 21 to move laterally or be misaligned relative to the pad because they are not connected to the lower mounting plate 20. The additional locking with the pneumatic cylinder 122' can also be dispensed with in the case of a low table speed.

Fig. 10 shows an exploded perspective view of the receiving device of the stamping and punching tool according to fig. 8, here with the

tool receiving plates

11, 21 pushed in and locked to each other, and fig. 11 shows an enlarged detail of fig. 10 before the upper mounting plate/tool plate unit 10/11 is locked. The upper tool receiving plate 11 collides with the positioning recess 143 against the positioning sleeve 16 of the guide pin 13 in the push-in direction. The lower tool receiving plate 21 hits the guide sleeve 31 with the positioning recess 133 in the pushing-in direction.

Fig. 12 shows a perspective view of a receiving device of the embossing and punching tool according to fig. 8, without a tool plate being pushed in; and figure 13 shows an enlarged detail view of figure 10.

The entire unit is in floating connection with the stamping head and the stamping table 100 acting from below. In this case, the embossing table moves. By means of two adjusting mechanisms, for example spindles or other actuators connected to the upper mounting plate 10 as in the first embodiment, the entire unit in the machine can be moved laterally with respect to the track travel direction 6 of the printed material or can also be offset at an angle with respect to the track travel direction. Both adjustments can 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 means of the inclined side edges 14 and the cylinder 12' moving in the direction 6) because the guide post/pin 13 is arranged in the rear, where "rear" 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 implemented in an irregular manner for cost reasons and also for accuracy reasons; it is a frame at which the mentioned components are arranged.
