    Description [0001] The present invention relates to an apparatus and a method for transporting goods, in particular to an apparatus and a method used in the field of paper handling for supplying goods to a processing, wherein the goods are in order flat goods, such as filled envelopes, packaging, groups of goods, leaves, groups of leaves, can act.
    Devices for transporting and processing envelopes are known in the art. Such devices include, for example, a printer to print on a surface of a filled envelope, such as an address, other information, advertising, or even to frank the envelope. In such known devices, which are intended to effect a processing of the transported goods, it is necessary that the material is moved with a predetermined distance with respect to the processing station; in the case of a printer, it is necessary to maintain a predetermined distance between the surface of the envelope and the printheads of the printer to ensure proper printing. In other examples, the envelope is fed to the processing station, and it is desired that the envelope with its upper surface be in a certain relationship with respect to the inlet of the processing station. The processing station may be e.g. to trade a meter, a labeler, a laminator or a coater.
    As long as the goods to be processed have the same thickness, the maintenance of the distance between the processing station and the surface of the goods is no problem, since all elements of the device can be adjusted accordingly. In the field of paper handling, however, the production of mailpieces results in envelopes of different thickness, depending on how much and with which the envelopes are filled. As a result, envelopes provided by an inserter have different thicknesses, so that there is no constant distance between the processing station and the surface of the envelope.
    In the case of printers can be provided in this situation, for example, to contact the filled envelopes in edge regions thereof by an upper guide, wherein the upper guide is set such that a distance of the envelope to the processing station corresponds to a desired distance and so Proper printing can be ensured in most cases. A disadvantage of this embodiment, however, is that due to the upper guides, for example, laterally engage with the transported envelope, not the entire envelope surface is available for printing, and always a border area remains free. Furthermore, the envelopes may contain goods that result in an uneven thickness distribution across the width and length of the envelope so that, particularly in the case of side, upper guides, which act only on edge regions of the envelope, different thicknesses exist in the area between the guides , Which results in that at least in places the distance to the processing station is less than the desired or required distance, so that it can lead to printing problems despite the leadership here. Although this can be suppressed by appropriate dimensioning of the guides or by providing further guide elements, however, the printable area on the surface of the envelope or the goods is thereby further restricted.
    Another known approach in the art is to detect the thickness of the material before its transport and its further processing, and depending on either the transport, the processing station or both to move relative to each other, so that for the processed Well, the desired distance from the surface to a reference plane can be dynamically adjusted. Fig. 1 shows a schematic representation of a plant for processing flat goods, as used in the prior art. Fig. 1 shows a transport 100 comprising a belt 104 revolving around two rollers 102a and 102b. Instead of the belt shown, other elements may be used, for example, chains with corresponding grippers or the like, as is known per se in the prior art. The rollers 102a and 102b are rotatably supported by the bearings 106a, 106b, wherein one of the rollers 102a or 102b are driven by a drive not shown in FIG. The transport 100 is arranged vertically adjustable, as indicated by the arrows 108a, 108b. The transport 100 further comprises the rollers 112a, 112b which, together with the rollers 102a and 102b, respectively define a roller pair in order to define a transport inlet or a transport outlet.
    The plant shown in Fig. 1 further comprises a processing station 200, which in the example shown comprises a printer 202 having printheads 202a, 202b. The printer may be, for example, an inkjet printer. Similar to the transport 100 and the printer is arranged vertically adjustable, as indicated by the arrow 204.
    The plant receives at the inlet 102a, 112a the goods which are moved by means of the transport 100 at the processing station 200 to effect printing of an upper surface of the goods. At the entrance, the system includes the sensor S to detect the thickness of the material so that, depending on the thickness, either the height position of the transport 100 and / or the height position of the printer 202 can be adjusted to a desired distance a between the printheads 202a, 202b and the surface of the goods G to be transported are maintained, and thus proper printing can be ensured.
    Compared to the approach described above, the upper guide elements for guiding the goods G includes, the approach according to FIG. 1 is advantageous because it can be dispensed with these upper guide elements, so that a full-surface printing of the goods is possible. However, the approach of FIG. 1 requires a considerable mechanical effort to move either the transport 100, the printer 202, or both, depending on a detected thickness of the material. This is also time consuming because it may be necessary to change the setting for each good. Printing can not take place until the adjustment is completed. Furthermore, the approach shown in Fig. 1 allows only a single item to be transported, since for each item the thickness is detected and a corresponding setting is made so that the throughput, ie the number of processed items per unit time, suffers. Furthermore, there is a problem when the goods have a thickness that varies along the width of the goods or along the length of the goods (in the transport direction T), since in this case the sensor may detect only an average thickness of the goods , and so there is no optimal distance in all areas of the material surface to the printhead and so a non-optimal printing takes place.
    Starting from the above-outlined prior art, the present invention seeks to provide an improved approach to the transport of goods, which avoids the disadvantages described above.
    This object is achieved by a device according to claim 1 and by a method according to claim 15.
    Preferred embodiments of the present invention are defined in the dependent claims.
    The present invention provides a device for transporting goods, comprising: a deformable transport means; and means for supplying a good to the deformable transport means; a means for impressing the goods in the deformable transport, so that a top of the material facing away from the deformable transport means has a predetermined height position with respect to the means for impressing the goods, and wherein the deformable transport means is formed to the predetermined height position of the goods outside the effective range the means for embossing the goods, characterized in that the means for embossing the goods comprise an element which is arranged at a distance from the deformable transport means, and on which a good for impressing in the deformable transport means on the element is moved past.
    The present invention provides a method for transporting goods, comprising the following steps:
    Feeding a good to a deformable transport;
    Impressing the goods in the deformable transport means, so that an upper side facing away from the deformable transport means of the goods has a predetermined height position with respect to a means for impressing the goods in the deformable transport means; Transporting the embossed material, wherein the deformable transport means is formed so that the predetermined height position of the goods outside the effective range of the means for imprinting the goods is at least temporarily maintained, characterized in that the means for embossing the goods comprise an element that with a distance to the deformable transport means is arranged, and that a good for impressing in the deformable transport means is moved past the element.
    Thus, the present invention provides embodiments according to a novel
    Approach to the transport of goods, which, while avoiding the above-described problems in known approaches, allows a transport of goods of different thickness in a simple manner such that their upper surface has a predetermined distance to and a predetermined orientation with a reference plane suitable for several consecutively transported goods regardless of their thickness and regardless of the course of the thickness along the length of the goods or along the width of the goods is always the same. According to the invention, therefore, for example, in approaches in which a good, for example, a flat element or a filled envelope to be printed by an inkjet printer, on the one hand created the opportunity to achieve a constant quality of the pressure, since the distance between the good / envelope and the printhead is always kept constant and at the same time the printable area is increased compared to conventional approaches.
    It is particularly advantageous that no special sensor is required to detect a thickness of the goods, since due to the inventive approach, the desired distance of the surface to the reference plane is essentially defined by the impressing of the goods in the deformable transport. For example, a roller or a belt with a predetermined distance to the surface of the undeformed transport means, so that a fed between the roller (or the belt) and the means of transport Good is stamped into the deformable transport so far that all embossed goods the same distance between have their surface and a surface of the undeformed transport. Thus, all goods have the same distance to a reference plane in which, for example, the printheads of a printhead are arranged. The deformable region also makes it possible to transport several goods of different thickness along the transport device, since they are impressed differently deep into the means of transport according to the inventive approach, whereby an increase in throughput can be achieved without increasing the processing speed, ie an increase per unit time processed goods.
    In the field of inserting the inventive approach is advantageous because the surface of the envelopes is always aligned parallel to the reference plane regardless of the filling of the envelopes, especially for different fillings.
    Another advantage of the inventive device is that can be dispensed with the complex mechanical movement and the corresponding control of the transport device and the processing device.
    Thus, according to the invention, an approach is provided in which a transport to the material is adapted so that its surface has a predetermined distance with respect to a reference plane, without the need for special sensors or active control, so that the above-mentioned throughput gain established.

    Fig. 2a shows a schematic representation of an arrangement which is similar to the arrangement shown in Fig. 1, but is equipped with the inventive transport. The plant shown in Fig. 2a is used, similar to the system shown in Fig. 1, to print on a surface of a transported goods G. The system comprises a transport 100 which, in the example shown, has a transport means 300 revolving around the rollers 102a and 102b. The transport means 300 is deformable, as will be described below in detail with reference to various embodiments. The deformability of the transport means 300 makes it possible to impress a good G1, which is moved by the transport 100, as shown at 302. The material G1 is stamped in such a way that its upper surface 304 has a desired distance d from the undeformed region 306 of the transporting means 300 or a desired distance d from a means for embossing the material into the deformable transporting means 300.
    In the embodiment shown in Fig. 2a, the processing station 200 again comprises the printer 202 with the printheads 202a and 202b, but the printer 202 is located at a fixed height position during processing of the goods and is not displaced during processing. Due to the embossing of the product G1 in the area 302, the approach according to the invention next to the desired distance d simultaneously sets the desired distance a of the surface of the product G1 to the reference plane in which the print heads 202a and 202b are located, so that the surface 304 of the goods G1 can be printed properly. It is not necessary to make the transport 100 adjustable in height, but this can remain on the bearings 106a and 106b during processing at a fixed height position. It should be noted at this point that the transport and / or the processing station 200 are basically adjustable in height, so that before the execution of a specific job, which involves the processing of a number of goods having a thickness within a predetermined range, a basic adjustment can be made to set a certain distance between the print head and the transport.
    For impressing the goods G1 in the transport means 302, the plant according to FIG. 2a further comprises a feed 400, which comprises a roller 402, which may be adjustable in height, as indicated by the arrow 404. The distance of the roller 402 is selected so that a good for transport Good, the goods left in Fig. 2a, so embossed in the deformable transport that the transport means remote top 304 of the goods the desired height position with respect to the non-deformed means of transport 306 or with respect to the roller 402 has. As can be seen, the product for impressing in the transport means 302 on the element for embossing (in Fig. 2, the roller 402) is moved past. The movement of the goods can be done by the feeder. Alternatively or additionally, the movement of the goods can be carried out by the means of transport, in particular if the goods are embossed only after being taken over by the means of transport (see, for example, below FIGS. 3 to 5. As mentioned, the element can be adjustable in height for impressing, eg Alternatively, the embossing member may be fixedly disposed at a height, and in such a configuration, the member may be arranged prior to processing an order corresponding to a desired height.
    After impressing the goods G1 this is transported by the transport 100 in the desired position with respect to the reference plane, since the deformable transport is formed to the effect of the imprinting of the material deformation at least during the time until the Good at the Processing station was moved past, to maintain. As a result, the predetermined height position of the goods outside the effective range of the means for impressing the goods is maintained at least temporarily.
    As can be seen from a comparison of Figs. 1 and 2, the inventive approach is advantageous because no sensor is required to detect a thickness of the goods. The material is impressed on the roller 402 (alternatively a belt) in the transport means 300, so that the transport means 300 deforms. The surface 304 is parallel to a reference plane in which, for example, the printheads 202a and 202b are arranged. Any differences in the thickness along the length of the product G1 or along the width of the product G1 are compensated by the embossing, since the deformable transport means 302 yields according to the thickness of the product G1, due to the force exerted by the roller 402 during embossing.
    As a result, not only can be dispensed with the sensors, but also in principle to the need to change the height position of the transport and / or the processing station 200 during operation, so that a simplified processing with increased process reliability is possible.
    According to the invention, it is also not necessary to provide upper guide elements for the good G1, since the indentation 302 in the transport 300 (deformation of the means of transport) is maintained at least temporarily outside the effective range of the means for impressing the goods, and the good accordingly moved in the desired height position, thereby simultaneously creating the opportunity to edit the entire surface 304 of the goods G1.
    Fig. 2a shows an arrangement in which the material is impressed by a roller in the deformable transport, so that it projects slightly beyond the surface of the non-deformed means of transport. The present invention is not limited to such a configuration. Fig. 2b shows a schematic representation of an arrangement similar to that in Fig. 2a, in which the material is impressed by a solid sheet 402 'in the deformable transport means so that it projects slightly beyond the surface of the undeformed transport means. Instead of the bent sheet 402 ', another element, e.g. a crossbar or the like may be provided.
    According to the embodiments described so far, the material has been embossed into the deformable transport means so that it protrudes slightly beyond the surface of the undeformed transport means. The present invention is not limited to such a configuration. Fig. 2c is a schematic representation of an arrangement similar to that of Fig. 2a, but the product is impressed by the roller 402 into the deformable transport means so as to be substantially flush with the surface of the undeformed transport means. In this case, the predetermined height position d of the upper side 302 of the material facing away from the transporting means 300 with respect to the undeformed transport means or the means for imprinting is zero or substantially zero. The distance a to the print heads in this case is equal to the distance between the transport and the printheads.
    Fig. 3 shows a further embodiment of the invention, in which the transport 100 additionally comprises elements to act on the deformable area to prepare this for receiving the goods or to effect a cancellation of the deformation. In Fig. 3, the elements which have already been described with reference to FIG. 2, provided with the same reference numerals and a re-description does not occur. As can be seen in FIG. 3, the transport device 100 in the region in front of the roller 402 comprises an activation device 500, which is provided depending on the design of the transporting means 300, in order to activate a region along the transport device, so that it is deformable, for example by applying the material of the transporting means 300 with a magnetic field, ultrasound, heat, electrical power, irradiation or a force. The device 500 can also act mechanically on the transporting means 300 in order to prepare it for receiving, for example by releasing movable elements or the like. The area prepared in this way is guided past the roller 402 and a product is embossed in the manner described above. The deformed region is designated by reference numeral 3021. After processing, the material leaves the plant. Depending on the design of the deformable transport means, a deactivation device 502 may be provided which acts on a deformed region 3022, which no longer contains the product, in order to release the deformation, as shown in FIG. The means 502 may be provided to act on the means of transport mechanically or by a magnetic field, ultrasound, heat, electrical power, radiation or a force to cancel the deformation. In the case of mechanical action, for example, it may be provided to release the mechanical elements in the deformed position so that they can be reset to their original position.
    Depending on the design of the means of transport, the activation or the deactivation device may comprise one or more elements which act on the means of transport by different means. If the means of transport e.g. Wax comprises, the activation circuit may have a means to heat the wax sufficiently so that a good can be embossed, and a further means for cooling the wax, in that the Good was embossed, so that it holds the shape.
    In other embodiments, it may be provided that the activation device extends along the transport, up to the processing station or beyond. In such a case, the activation can allow the deformability of the means of transport, and the goods are embossed and transported. After processing, the active area ends and the transport returns to its initial, undeformed shape.
    Depending on the design of the transport means 300, the activation device and / or the deactivation device may be provided, wherein other embodiments have a transport means 300, which maintains a deformation for a predetermined period of time, which is sufficient to the held in the deformable region Good to transport and move, and then returns automatically in its undeformed state.
    Fig. 4 shows the embodiment of Fig. 3, in which the feeder instead of the roller 402 comprises a belt 406 which runs around two rollers 408a and 408b. Further, in the embodiment shown in Fig. 4, the processing station 200 is not a printer, but a subsequent to the transport 100 station, which takes over the estate G1 with a desired height position and further processed.
    Fig. 5 shows an embodiment of the invention according to which a plurality of goods with the same or different thickness can be moved simultaneously by the transport device 100, wherein Fig. 5a shows a system similar to that in Fig. 3, wherein between the printer 202 and the Roll 402 exemplified three goods G1 to G3 are shown.
    FIG. 5b shows an enlarged representation of the goods G1 to G3 from FIG. 5a. The different thicknesses of the goods are recognizable and correspondingly the different insertion depths e1, e2 and e3, where e3 <e1 <e2. Due to the approach according to the invention, the goods G1, G3 are embossed into the transport means 300 such that their upper surfaces 304 all have the same distance d from the non-deformed region 306.
    Thus, in contrast to the known approach described with reference to FIG. 1, the article according to the invention according to the embodiment of FIG. 5 enables the simultaneous movement of a plurality of goods independently of differences in thickness, as a result of which, as described above, the throughput, i. the number of goods processed per unit time is increased without requiring an increase in the process speed, that is, the printing speed and the transport speed, so that the process reliability can be improved while increasing the throughput.
    Examples of the design of the means of transport will be explained in more detail with reference to the other figures, wherein the transport means 300 either by mechanical elements or by a corresponding deformable
    Material is formed. First, embodiments will be described with reference to FIGS. 6 to 9, which have mechanical elements for generating the deformable region, and then follows with reference to FIGS. 10 and 11, a description of embodiments for a transport, which has a deformable material.
    6, an embodiment of the deformable transport means is explained in more detail, wherein Fig. 6a shows an isometric view of the embodiment, and Fig. 6b details with regard to the design of the movable crossbars.
    In Fig. 6a, reference numeral 300, the transport means 300 schematically shown with reference to the preceding figures is shown, which is deformable, as explained above. Also shown in Figure 6a is a portion of the feed means in the form of the two rollers 402a and 402b arranged in the illustrated embodiment and the desired distance between a surface 304 of the stock G1 to a reference surface and the surface of the undeformed transport means, respectively define. The feeder further comprises in the embodiment shown counter rollers 406a and 406b, which are mounted vertically movable to yield slightly when inserting the goods G1. Fig. 6a further shows an output roller pair 112b1 and 112b2.
    The transport means 300 shown in Fig. 6a comprises two parallel belts 600a, 600b between which extends a plurality of transverse rods 602, which are rotatably mounted on respective slip clutches 604a and 604b.
    Fig. 6b shows details of the arrangement of the crossbars. Shown in Fig. 6b is the belt 600a which is rotatably supported in a guide 606 with supports 608 secured thereto at predetermined intervals along the belt 600a, which are moved together with the belt 600a. On the support 608, a crossbars 602 is disposed over the slip clutch 604a, wherein the attached to the slip clutch 604a end 602a of the cross bar 600 is rotatable upon application of the cross bar 602 counterclockwise or clockwise, depending on an applied Good G1 a height position of the Change crossbar 602 with respect to the starting position shown in Fig. 6b, so that the height position of the cross bar 602 changes depending on a thickness of the supplied good G1. The slip clutch 604a is configured such that the crossbar 602 maintains its position without force, but upon application of a force, for example by impressing the material G1, but is moved from the position shown in a deflected position along the periphery of the disk shown in Fig. 6b and in this for the transport of goods G1 remains. After completion of the transport can be acted upon by suitable means on the cross bar 602 to bring them back to the starting position shown in Fig. 6b.
    The functionality of the embodiment described with reference to FIG. 6 will be described below with reference to an envelope G1 whose surface is to be printed. As mentioned above, printing on the surface 304 of the envelope G1, depending on the thickness of the envelope, requires adjustment to maintain a desired height. According to the invention this is effected by the deformable transport means 300, in which the height compensation by the individual, adjustable in height crossbars 602 is realized. The crossbars 602 are mounted on the transport belts 600a and 600b, and the adjustment and fixing of the crossbars 602 are performed by the slip clutches 604a and 604b. The transverse rods 602 are brought to the starting position in the lower belt area (see Fig. 6a [return]). If no envelope runs through the unit, then the cross bars 602 remain in their set starting position. This means that they are held in their uppermost position (see Fig. 6b) and this position does not change. In the upper belt area, at the inlet 402, the boundary rollers 402a and 402b, or alternatively a belt, are installed for the boundary of the upper side 304 of the envelope. When feeding envelopes, the transverse rods are brought to a corresponding height position, depending on the thickness of the supplied envelope, so that the envelope surface 304 always occupies the same height position.
    The crossbars are mounted at both ends by respective slip clutches, so that regardless of the envelope filling always takes place with respect to the Kuvertoberseite, as explained above, for example, in an uneven distribution of the thickness across the width of the envelope, a crossbar at one end has a height position that differs from the height position at the opposite end. Likewise, changes in thickness along the length of the envelope are compensated by deflecting the successive crossbars to different extents.
    After the envelopes have been positioned to the desired height, they are passed under the printer and printed and output for further processing. After printing can be provided according to embodiments, bring the envelopes back to the original transport height to supply them to a post-processing. In this case, the slip clutches can be acted upon, so that they are moved back to their original position. This can e.g. by utilizing a spring force or by a mechanical action on the crossbars, e.g. by a stop / bracket or a backdrop, done. According to embodiments, the provision of the transverse rods can be carried out in their starting position after each circulation. Alternatively, it can also be provided to selectively activate or deactivate the return means, so that e.g. at the same thickness of the goods or in goods becoming thicker no provision is made, so that an unnecessary movement of the crossbars is avoided.
    The embodiment described with reference to FIG. 6 is advantageous, since only the low mass of the transverse rods, which are in contact with the envelope, has to be moved when leveling the height. The envelopes can be guided along the means of transport substantially without Gutabstand, so that the throughput increases without the speed of transport must change. The height compensation is done without additional actuators or sensors and the envelope surface is always aligned, regardless of the envelope filling.
    Fig. 7 shows the structure of a device according to Fig. 6, in which instead of the rollers 402a and 402b in the inlet region, a belt 408 is arranged. The assembly rests on a support 610. Further, the drive 612 is seen, which drives the belts 604a, 604b.
    Instead of the mechanical elements described with reference to FIGS. 6 and 7, these may also be configured differently. Fig. 8 shows a further embodiment for the transport means 300, wherein Fig. 8a shows the undeformed state, and Fig. 8b shows the deformed state. In Fig. 8, an example is shown in which the transport means 300 comprises a plurality of pins 800, e.g. Metal pins which are mounted vertically movable in a carrier 802. Further, a locking mechanism 804 is provided which causes a vertical deflection of the individual pins 800 down a locking thereof in the deflected position. The area shown in Fig. 8 is a section of the transport described with reference to FIGS. 2 to 5, which is configured circumferentially. In Fig. 8a it is shown that all the pins 800 are not deflected downwardly, so that the nail bed shown forms, in which the upper ends of the pins 800 are arranged in a common plane. Fig. 8b shows a situation in which a good G1 (see dashed line) has been embossed in the transport, the Good along the longitudinal direction and / or along the transverse direction has a different thickness. The impressing of the product G1 causes a deflection of a number of pins 800 down so that they reach the locking mechanism 804 and are held in the deflected position. The deflected pins define the deformed region 302, wherein the impressing of the material G1 by the input rollers, for example, causes a desired distance d of all the imprinted goods G1 with respect to a surface of the undeformed region 306 of the conveyor 300.
    In the embodiment according to FIG. 8 it can be provided that the individual metal pins 800 are arranged during a return transport from the outlet to the inlet of the arrangement (see FIG. 3) in a position which does not allow a vertical displacement. By means of the device 500 may be provided to act on the locking structure 804 to activate them, so that when impressing the goods G1, a deflection of individual pins and a locking of the same is made possible. In the return, by means of the deactivation device 502, the locking device 804 can be acted upon to release the deflected pins 800 so that they are moved back to their original position (FIG. 8a), for example due to a return force provided by a spring if necessary be locked.
    Fig. 9 shows a further embodiment of the embodiment of the deformable transport means using mechanical means. 9a again shows the undeformed state, and FIG. 9b shows the state in which a product has been embossed into the transport means 300. In the exemplary embodiment shown in FIG. 9 a, the transporting means 300 comprises a plurality of spring elements 900, which are supported by a carrier 902. The carrier 902 facing away from the ends of the spring elements 900 carry a transport surface 904 of a deformable material. Alternatively, the individual spring elements 900 may also have individual surfaces on their ends facing away from the carrier 902, so that the adjacent surfaces of the plurality of spring elements 900 define the surface 904. By impressing a good G1, a deflection of individual one of the spring elements takes place downward, as shown in FIG. 9b, so that the deformed region 302 adjusts. According to the imprint of the goods G1 whose surface remains at the distance d above the non-deformed region 306. In the embodiment shown in Fig. 9, the spring elements 900 can be mechanically acted to effect locking thereof in the deflected state, wherein the return is again acted to release the lock. The locking of the spring elements in the manner shown in Fig. 9b can be done by mechanical means, which lock the deflected spring elements at the deflected position, the compressed position in Fig. 9b. Alternatively, the spring elements can also be electrically actuated, so that they remain in their deformed position in response to a control signal and release them only when a corresponding electrical signal is applied or no longer applied.

Further, means 1006 is provided which, for example, corresponds to the activation means 500 shown in Figure 3 to allow activation of the fluid 1004, e.g. to cause a change in the viscosity of the fluid (e.g., wax) so that it deforms upon impressing a product and also retains the deformation accordingly. This can be done for example by applying the fluid with a mechanical force, electrical power, magnetic radiation, ultrasound or the like. Fig. 10b shows the transport device 300 after the introduction of the goods G1, in turn, as described above with reference to FIGS. 8 and 9, the imprint is such that the surface of the good G1 a distance d to the non-deformed surface 306, regardless of how the thickness distribution of the product is along the length or width of the product. The device 1006 can also be provided to be effective as a deactivator 502 (see FIG. 3) for, after transport, the fluid with a mechanical force, electrical power
