Definitions
- the present invention relates to a device for supporting and heating of tools in the form of metal plates used for embossing hot and / or cutting and transfer by hot pressing of portions of films, preferably metallic, on a paper or cardboard substrate mainly.
- Such operations are, for example, carried out in a machine comprising a platen press, in which a sheet of cardboard is brought there to be printed with given patterns from a strip generally metallized pipe between this sheet and the upper box spring heating.
- the pressure required to transfer the metallized film onto the sheet of cardboard is given by the movable lower bed base of the press platinum.
- This movable bed base is generally equipped with a stamping plate, against which the counterparts of each of the tools in the form of upper box spring plate.
- These tools are generally known from a person skilled in the art under the term of stereotypes. So in a vertical movement periodic, the lower bed base will press the counterparts against the clichés correspondents, sandwiching the cardboard sheet above which is stretched the metallized strip.
- the heating of the pictures is therefore made in contact with the nests chassis of bees which, itself, is in direct contact with the upper box spring heating.
- the latter constitutes a heavy and massive part capable of withstand the high pressures generated by the lower movable base during stamping the metallic strip and sometimes even during an operation simultaneous embossing of the sheet.
- Stamping and embossing strength varies depending on the total surface of the patterns to be stamped and can be typically of the order of 1 to 5 MN for areas of worked leaves of almost one approximately square meter. It is inside this box spring that the device resides to heat the honeycomb chassis and therefore the clichés being fixed there.
- Such a box spring generally comprises a massive block rendered secured to the machine frame. Against the lower surface of this block is found at least one support plate, in the thickness of which a plurality of parallel conduits are machined making it possible to house a twenty electric heaters. This support plate is still divided into ten zones, so that the heaters are located in each of these zones, can be supplied together with independently. To this end, an electrical supply network takes also placed inside the upper box spring and connects each group heating body to an external power source. In order to adjust the temperature of the photos to an optimal value, generally between 50 ° C and 180 ° C, the electrical circuit is provided with a thermostatic regulation connected to a plurality of thermal probes. These the latter are generally housed as close as possible to the honeycomb chassis and are distributed according to the areas defined by the different groups of heater.
- Patent FR2'639'005 describes a hot foil stamping device analogous to that exposed so far.
- the heating device of one of the box springs has six independent heating elements separated from each other others by intervals of the order of a millimeter.
- Each heating element consists of a stack of different plates.
- Under this plate is a copper plate acting as a heat distributor.
- Below this last is another milled plate of grooves in which are placed the heating resistors.
- This set of plates rests finally on a last plate formed by compact plastic strips alternated with honeycomb slats. This last plate constitutes a thermal insulation preventing excess heat dispersion to the rest of the bedspring.
- Such heaters have multiple disadvantages which do not facilitate the improvement of the performance of these machines and also make them not very versatile.
- these disadvantages we will mainly mention the great thermal inertia of the many parts massive of these heaters which decrease the performance of the machine when it comes to quickly adapting to new temperature.
- Such a situation can arise, during the same work stamping, when a batch of cardboard sheets is no longer in the same temperature than the previous batch.
- the reasons for such a difference in temperature between these two batches of sheets which can be directly linked to their place of storage, with uneven ambient temperatures, or be due to an increase in machine speed.
- By working sheets of cardboard at a lower temperature it will be necessary to compensate for the heat loss of the plates coming into contact with these sheets in shortest possible time.
- the thermal inertia of all the parts that include the heating devices known to date may require no less than ten minutes before the thermal probes can capture the temperature variation.
- the reaction time to be able to correct such sudden temperature differences is therefore very long compared to the production speed which can be of the order of 4000 or even 7000 sheets per hour.
- Another disadvantage is the difficulty of the systems heating systems to regulate the temperature.
- the heating zones being relatively coarse surfaces, regulating the temperature of areas bordering the honeycomb chassis is generally difficult to get it satisfactorily. Indeed, these peripheral areas are subjected to a temperature gradient which shows a decrease in the temperature of the shot as we approach the edge of the heating plate. This decrease is caused either naturally by surrounding conditions, where the ambient air is at a much lower temperature to that of the stereotypes, either artificially by a wind tunnel placed upstream of the platen press, used to facilitate detachment of the rest of the strip metallic, once stamped on the cardboard sheet. Therefore, if these zones are located not far from the periphery of the heating plate, their temperature can never be made uniform. There will follow a notable reduction in the quality of the transfer of the metallized strip, or even the appearance of faults in these places.
- heaters as described, are difficult to repair and maintain.
- the main organs subject to breakdown being the electrical resistances and the temperature probes.
- the area heating system which could even cripple the entire machine in the event that one or even several photographs were found, even partially, in this area.
- the object of the present invention is to remedy, at least in part, to the aforementioned drawbacks.
- the object of the present invention allows quick and user-friendly adaptability of cutting and stamping machines thanks to a much simpler device to set up and remove from a ordinary box spring. It thus considerably reduces the times necessary to carry out these transformations and improves the versatility of these production machines. It also increases energy efficiency of heating plates, choosing and targeting precisely the different zones to be heated, to decrease the power necessary heating and thereby reduce consumption costs by electricity.
- the object of the present invention also covers the possibility of no longer having to systematically resort to the arrangement of temperature inside the box spring thanks to a system self-regulation integrated in each heating element. In addition, it presents the advantage of considerably reducing the heating and cooling of the machine, respectively before and after production of a given job.
- FIG. 1 shows schematically the main organs a platen press 1 in which the device 20 for supporting and heating of the present invention is arranged therein.
- the platen press 1 is essentially consists of a fixed upper bed base 2 and a box spring lower 3 movable in the vertical direction. Between these box springs at least a metallic film or strip 4, unwound from a reel 5 by a pair of feed rollers 6. Thanks to the arrangement of a plurality of feed rollers reference 7, this metallized strip then goes around the upper bed base 2. It is tensioned by a pair of drive rollers 8 before being removed from the machine by a deflection member 9 and to be evacuated by a pair of brushes 10 towards a recovery tank 11.
- a substrate such as a sheet 12 of cardboard or other material, is deposited on the lower base by a transport member, for example a clamp bar 13 mounted on a chain train 14, as partially shown.
- the lower bed base 3 is equipped with a stamping plate 15 against which at least one counterpart 16 is fixed there.
- the support and heating device 20 of the invention equipped with at least one plate 17 intended to be heated.
- a new sheet 12 is routed and positioned by the clamp bars 13 on the lower bed base 3 equipped with counterparts 16.
- a new portion of metallized strip 4 is unwound from the coil 5 and then stopped next to the pictures 17.
- the rise of the lower bed base 3 being then actuated, it causes the closing of the platen press 1 during which each counterpart 16 comes to fit into the corresponding plate 17. Being sandwiched between these two organs, the sheet 12 and the portion of metallized strip 4 are strongly compressed against each other.
- This compression force to which is added the heat given off by the plate heated, used to cut the imprint of plate 17 in the metallic strip 4 and stick this imprint against the sheet 12 using an adhesive layer specific to each metallized strip.
- a blower 18 allows to breathe air to facilitate separation of sheet 12 from the remaining skeleton metallic strip which sometimes tends to stick to it. Sheet 12 stamped is then removed from the press by the clamp bar 13 and a new cycle can begin.
- FIG. 2 illustrates in more detail the device 20 for supporting and heating which allows to fix the stereotypes 17 of the upper box spring and to raise their temperature up to an optimal working value.
- the device 20 comprises in particular a first non-conductive insulating plate 21 electricity or even thermally insulating, against which is supported by a bottom sheet 22 of copper for example. Against the in front of this sheet is pressed an insulating surface 23 having a almost infinite ohmic resistance.
- the assembly constituted by the insulating plate 21, the bottom plate 22 and the insulating surface 23 can form a whole and constitute thus an organ called base plate 40.
- a honeycomb frame 24 comes then be positioned against this base plate 40, more precisely against the insulating surface 23.
- This chassis is identical in all respects to those used for hot stamping operations in known platen presses of the skilled person.
- a honeycomb chassis has a multitude openings 25, also distributed over its entire surface, and has dimensions substantially equal to the maximum sheet size that it is possible to work with the press in question. Being very expensive to realize, it will be understood that it is also advantageous not to necessarily have to use a specific chassis to be able to implement the object of the present invention.
- the openings 25 are preferably circular in shape and right through the thickness of the honeycomb chassis 24. Through each opening 25 we can see a hole 26 made in the insulating surface 23 so that it is also possible to see part of the bottom sheet 22.
- the openings 25 and the holes 26 are preferably concentric as illustrated in FIG. 2.
- Each opening 25 can receive an independent heating element 30, taking at least support, at one of its ends, against the stripped part of the bottom plate 22 and having, at the other end, a front part intended to come into contact with the back a plate 17 plated and fixed against the outside surface of the nests chassis bee 24.
- FIG. 3 gives a schematic illustration of an element heater 30 of the device 20 of the present invention.
- Each element heater consists in particular of a capsule 31 manufactured in a insulating material which does not allow electrical current to pass.
- This capsule 31 is crossed by an electrode essentially consisting of a bar 32.
- One end of this bar crosses the hole 26 of the insulating surface 23 and comes into contact with the bottom plate 22, and the other end supports a seat 33 sliding along the vertical axis of the bar.
- Elastic means such as a compression spring 34, pushes this seat 33 in direction of the exterior of the opening 25, facing the back of the plate 17.
- the spring of compression 34 is preferably integral, at its ends, respectively from the inner bottom of the capsule 31 and the inner surface of the seat 33.
- any electrical resistance 35 of the heating element 30 is always found properly pressed against the back of plate 17 when the latter is fixed on the honeycomb frame 24. It is intended that the heating element 30 comes snap into opening 25 so that it is easily removable. However, any other means of attachment allowing it to be put on and easily removing it from the opening 25 may also be suitable.
- the bar 32 and the seat 33 constitute one of the electrodes of the support and heating device 20, while the honeycomb frame 24 and plate 17 constitute the other electrode of this device.
- the bottom sheet 22 is therefore connected to the positive polarity of the source electric power and the honeycomb frame 24 is connected to the polarity negative so that the visible parts, such as the chassis and the plate, of the electrical circuit are connected to earth and thus presents no danger when the device is powered on.
- the insulating plate 21, the insulating surface 23 and the capsule insulating 31 which consist in electrically separating the bottom sheet 22 from all the other parts of the device 20 connected to the ground of the platen press 1.
- the electric source not forming part of the present invention, it will not be not described in more detail here.
- the network of electrical wires allowing to connect the bottom plate 22 and the honeycomb chassis 24 to the terminals respective to the electrical source, has no particularities. However, we will still mention that these connections are useful achievable in a very simple way given the access, particularly easy from the outside, offered by both the bottom plate and the honeycomb frame.
- the device 20 of the present invention has no network of internal conductors for the power supply of the electrical organs which it comprises.
- the plates 17 are fixed by means of tight clamps in a few selected openings of the honeycomb frame, near the plate 17. Contributing nothing to the understanding of the present invention, these fastening means have simply not been shown in FIG. 2. However, it will be noted that the device 20 of the present invention therefore allows advantageously to keep this method of fixing the pictures. He never forced therefore by no means the user to invest to equip themselves with a fixing means specific to the device of the present invention.
- the electrical resistors 35 can be present, for example, in the form of ceramic pellets used for heated glue guns in the field of building construction. They can therefore be easily found in specialized shops. These lozenges generally exist in different types, each of which corresponds to a different ohmic resistance.
- the device of the present invention can advantageously be equipped with different electrical resistors 35, depending on the specificity of the work carried out in the platen press. It is therefore also possible to have at the same time, in the device 20, several pads of different ohmic resistances. So it would become possible to heat more part of a plate compared to another or in relation to the rest of the photo for example.
- the device of the present invention makes it possible to place the heating elements 30 at will over the entire surface of the chassis 24, and more judiciously to place them at least inside the covered areas by snapshots 17. Thus, only these snapshots and the chassis surfaces that they occupy will actually be heated by the heating elements 30.
- the pellets, forming the electrical resistors 35 are in direct contact with plate 17. It also results in a gain not negligible from an energy point of view.
- certain types of these resistances electric vehicles could have an inherent self-regulatory power of these pastilles.
- these lozenges could have a composition chemical whose ohmic resistance varies according to the difference between the actual temperature of the tablet and a determined maximum temperature.
- regulating the electric current consumed by each resistor would be done automatically and independently until the tablet reaches the maximum set temperature for which it was designed.
- the heating elements 30 located not far from the blower 18 would automatically absorb more electrical current than those located more in the center of the honeycomb frame, this in order to compensate for the loss of heat generated by the movement of air from the blower. Thanks to that local compensation, which sometimes could even be punctual, a snapshot 17 located near the blower 18 could therefore be heated to a value of almost uniformly.
- this kind of pastilles would no longer require having to systematically use the arrangement of temperature sensors to control the regulation of the different zones heated.
- the support device 20 and heater of the present invention comprises only a few elements and, on the other hand, that the latter are almost all in the form of plates, can be very easily mounted against the bare upper box spring any platen press. Conversely, the disassembly of the device 20 to equip the box spring with tools for cutting cardboard sheets presents no more difficulties.
- FIG. 4 represents a variant of the preferred device of this invention.
- This variant consists in using a base plate 40 formed of a plurality of successive inseparable, insulating and conductive layers 41 42, replacing the insulating plate 21, the bottom plate 22 and the insulating surface 23.
- Such plates are known under the name of circuits multi-layer prints and are commonly used in the field of electronics and IT for making electronic cards, such as graphics cards, motherboards or expansion cards for example. Serving as a support, these multi-layer circuits are therefore a kind of millefeuilles conductive and insulating layers on which are generally soldered electronic components
- the electronic cards To that the electric current can be brought to the surface, from the different conductive layers 42 internal to external surface contacts 44, the electronic cards usually have vias 43, a kind of small rivet insulated metal, which cross all the upper conductive layers, without making electrical contact, until reaching their destination layer at which they are electrically and mechanically connected by a weld 45.
- the heating element 30 comprises an envelope 51 insulator similar to the capsule 31 referred to in Figure 3.
- an insulating jacket 52 containing the main desired members, namely a piston 53 actuated by an elastic actuator 54 such as a compression spring, an electrical resistance 35, a cap 55 conductor and an electronic device 56 which can be a measurement device such as a thermal probe for example.
- the electrical resistance 35 is connected to a medium voltage source via a first electrode 61 intended to be connected to one of the contacts 44 whose potential equivalent to the voltage of 230V for example, and through a second electrode 62 intended to be connected to a second contact 44 whose potential is equivalent to zero voltage for example.
- a third electrode 63 intended to be connected to the last contact 44, allows to put the electronic device 56 under a low voltage, for example 5V, thanks to the potential difference existing between the second and the third electrode.
- the electrodes 61, 62 and 63 are regularly arranged around the insulating jacket 52 and pass through this last through passages 57, to be able to be connected to the element electrical or suitable electronic component.
- the piston 53 is preferably made of insulating material.
- an elastic actuator 54 as a spring
- a piston 53 both conductors.
- the organ electronics 56 is, in the example illustrated in FIG. 5, arranged inside the piston 53.
- the purpose of the cap 55 is here to double the contact surface of electrical resistor 35, thereby improving diffusion heat against plate 17, while keeping this protected pellet at inside the envelope 51.
- This cap 55 can also be produced in a material such as copper or mica as far as this material has good thermal conductivity. However, it could be also considering removing this cap 55 or replacing it simply by the electronic measuring device 56. It is quite clear that the number of electrodes provided in the variant of the heating element 30 could be different in order to obtain either an improvement of this element, or a simplification of its design for example.
