Description

The invention relates to a firing device, in particular a punching device or riveting device, comprising a round tool body with a feed device which is designed for feeding firing elements, in particular punching elements or riveting elements, and is connected to a tool head, which tool head has a tool cage which is connected to the tool base body by means of an intermediate plate, wherein the intermediate plate and the tool cage delimit in sections a receiving space for at least one sensor element.Weft devices of the type mentioned at the beginning, for example punching devices or riveting devices, are fundamentally known from the prior art. For mounting the tool cage on the intermediate plate, fastening means are usually provided, for example screws. For reasons of symmetry, such fastening means are usually arranged in the same way, in particular point-symmetrically, with respect to a center point or a center axis of the shooting device. This has the result that the intermediate plate and the tool cage can be mounted in different orientations relative to each other, since, for example, when rotated through 180°, similar fastening openings come into alignment with each other or the hole pattern of intermediate plate and tool cage is aligned with each other even when oriented in a rotated manner. As a result, mispackaging can also be carried out.In other words, the intermediate plate and the tool cage of the tool head can be connected to one another in a incorrectly oriented manner, since the hole pattern of the fastening openings is provided symmetrically. This can lead to the situation that a receiving space for a sensor element, which is bounded in parts by the tool cage and the intermediate plate, is not produced correctly, since the individual subspaces of the receiving space are not aligned with one another in the case of incorrect orientation or are not mutually engaged or arranged on one another on account of the incorrect installation.If the intermediate plate is nevertheless connected to the tool cage in the incorrect orientation in order to form the tool head, this has the result that the receiving space for the sensor element is not sufficiently available and the sensor element can therefore be squeezed between the intermediate plate and the tool cage. On the one hand, this has the result that, owing to the initial incorrect installation of the tool head, the intermediate plate has to be separated from the tool cage again and has to be mounted again in the correct orientation. Further, damage to the sensor element may occur due to the crush of the sensor element.The invention is based on the object of specifying a shooting device which is improved in comparison with it, in which in particular incorrect installation of the intermediate plate on the tool cage is ruled out.The object is achieved by a shooting device according to claim 1. The claims dependent thereon relate to possible embodiments.As described, the invention relates to a shooting device, in particular a punching device or a riveting device. The firing device comprises a tool base body with a feed device which is designed for feeding firing elements, in particular punching elements or rivet elements. The feed device is connected to the tool head or is designed in sections, for example as a channel or tube in the latter, so that the corresponding shot elements can be fed into the tool head. The tool head has a tool cage which can be connected to the tool base body of the shooting device by means of an intermediate plate. In other words, the intermediate plate lies in the vertical direction, for example in the feed direction of the shot elements, between the tool cage and the tool base body.The intermediate plate and the tool cage of the tool head each delimit a partial space of the receiving space for at least one sensor element in sections. In other words, a sensor element can be arranged in the tool head, which is accommodated in part in the first subspace of the receiving space in the intermediate plate, and in part in a second subspace of the receiving space, which is formed in the tool cage. In other words, the sensor element is accommodated in the accommodation space, which is formed by corresponding partial spaces in the intermediate plate and the tool cage when the intermediate plate and the tool cage are correctly installed.The invention is based on the finding that the tool head is connected to the tool base body by at least two fastening means, wherein fastening openings formed to receive the fastening means are arranged asymmetrically on the intermediate plate and / or the tool base body. The asymmetrical design of the fastening openings fixes the orientation of the tool cage and of the intermediate plate in which the tool cage and intermediate plate can be fastened to one another. In other words, there is no symmetrical hole pattern of the fastening openings, so that the usually possible at least two orientations of the intermediate plate and of the tool cage are just not given, but there is exactly one possible orientation in which the intermediate plate can be mounted on the tool cage, namely when the fastening openings are aligned with one another.This ensures that a mounting of the tool cage with the intermediate plate can only lead to an engagement of the fastening means in the fastening openings if the correct orientation is present. If an incorrect orientation is nevertheless attempted, the fastening means cannot be brought into engagement with the fastening openings, in particular screws cannot be screwed into the corresponding threaded bores, with the result that at least damage to the sensor element accommodated in one of the subspaces of the receiving space can be prevented, since the fastening means cannot be tightened.According to one embodiment of the shooting device, it can be provided that a hole pattern of the fastening openings on the tool cage and / or on the intermediate plate is formed asymmetrically. The hole pattern of the fastening openings can be viewed in particular in a transverse plane which runs transversely to the longitudinal axis of the fastening means. The asymmetry can be understood in particular as a point symmetry with respect to a central axis, for example the feed direction or the firing direction in which the firing elements are applied to the component, i.e. in particular punched or riveted. The hole pattern of the fastening openings therefore only comes into alignment if the tool cage and intermediate plate are correctly oriented with respect to one another. If an opposite or reversed orientation is present, the fastening openings do not come into register, so that an introduction of the fastening means at least into one type of fastening openings is prevented.According to a further development of the shooting device, the tool cage and / or the intermediate plate can have two first fastening openings and two second fastening openings, wherein either the two first fastening openings or the two second fastening openings are opposite each other with respect to a central axis. In other words, exactly two fastening openings, namely the corresponding first fastening openings or the corresponding second fastening openings, are situated opposite one another with respect to a central axis, wherein the respective other fastening openings are not situated on a connecting line through the central axis, but one of the fastening openings is positioned differently from this connecting line. This ensures that all the fastening openings of the same type come into alignment with one another only when the correct orientation is selected. If a different orientation is selected, at least one fastening opening, for example in the intermediate plate, is not in alignment with its counterpart, for example in the tool cage, so that an insertion of a fastening means through the corresponding fastening openings is not possible.The fastening openings can relate, for example, to through-bores or threaded bores or can have these at least in sections. Stepped bores are likewise understood as through-bores. In a development of the shooting device, it can be provided that exactly two first fastening openings, in particular as through-bores, and exactly two second fastening openings, in particular as threaded bores, are formed or at least partially encompass these. In other words, a fastening means, in particular a screw, can be passed through the tool head through the fastening openings provided as through-holes, which engage with a thread in the tool base body. The second fastening openings designed as threaded bores can be provided in particular in the tool cage and can be brought into engagement with fastening means which can be guided through through-bores in the intermediate plate and can be screwed into the fastening openings designed as threaded bores in the tool cage.In other words, a fastening means can be inserted through one of the through-holes in the intermediate plate and screwed into a threaded hole which is aligned with the previously described through-hole of the intermediate plate. Alternatively, the fastening openings in the intermediate plate can also have threaded sections into which fastening means introduced into the fastening openings in the tool cage can be screwed. The joined tool head can then be connected to the tool base body via the through-bores in the intermediate plate and tool cage. However, this is only possible if the intermediate plate and the tool cage are oriented correctly with respect to one another, since otherwise the asymmetrically arranged fastening openings are not aligned and assembly is thus ruled out. In this case, those fastening openings which are provided for connecting the intermediate plate to the tool cage are preferably selected asymmetrically, with the result that the joining of the tool cage to the intermediate plate is prevented if the orientation is incorrect, with the result that damage to the sensor element can be ruled out.As described, an asymmetrical design of the fastening openings is to be selected. In principle, the asymmetrical design can be achieved as desired. According to one embodiment of the shooting device, it can be provided that a size and / or a position of at least one first fastening opening or second fastening opening deviates from the respectively corresponding opening. As already described, two first fastening openings and two second fastening openings are preferably provided on the intermediate plate and the tool cage. In the described variant, for example, the size of one of the first fastening openings differs from the respective other first fastening opening or one of the second fastening openings differs from the other second fastening opening.The same can apply to a position of the fastening openings, so that at least one of the fastening openings is selected asymmetrically with respect to the other fastening opening of the same type. The deviation in position can be chosen by a defined distance, for example by one half of the diameter of the fastening opening. It can likewise be provided that a position of a first fastening opening is interchanged with a position of a second fastening opening, so that only mounting in a unique orientation is possible. As described above, it is also possible to arrange one of the fastening openings outside a connecting line through the center point of the other fastening opening of the same type and through the center point of the tool cage or the intermediate plate.The described firing device can furthermore be further developed to the effect that the second fastening openings are arranged closer to a central axis of the tool head than the first fastening openings, wherein a second fastening opening is arranged closer to the central axis than the other second fastening opening. As described, the first fastening openings can be provided for fastening means which are provided for fastening the tool head to the tool base body. The first fastening openings can therefore be provided both in the tool cage and in the intermediate plate as through-bores, wherein these can be designed as stepped bores in the tool cage.The second fastening openings accordingly serve for mounting the intermediate plate on the tool cage. For example, the second fastening openings of the intermediate plate can be designed as through-bores or stepped bores and the second fastening openings in the tool cage can be threaded bores or comprise such bores, wherein a reverse design is likewise possible. When viewing the tool cage and the intermediate plate, one of the two second fastening openings is accordingly arranged closer to the central axis than the respective other second fastening opening. This has the result that the design or arrangement of the second fastening openings is asymmetrical and therefore it is only possible to mount the tool head when the second fastening opening arranged closer to the central axis is in alignment with the corresponding second fastening opening, which is present only in a single orientation because of the symmetrical design.In the shooting device, it can further be provided that the second fastening opening arranged on the side opposite the receptacle for the sensor element is arranged closer to the central axis of the tool head than the other second fastening opening. In other words, the fastening opening that is situated opposite the receptacle for the sensor element is moved closer to the central axis of the tool head. As a result, it is not necessary to change the second mounting hole disposed on the side where the sensor element receptacle is formed. Instead, the opposite second fastening opening is changed in its position, for example moved closer to the central axis, so that an impairment of the receptacle for the sensor element can be ruled out.As described, in the shooting device, a sensor element is accommodated in the receptacle. The sensor element can basically be designed for detecting at least one shot element fed in the tool head. For example, the sensor element can thus ensure that a weft element is inserted into the tool head and that only the required number of weft elements is supplied in the tool head.In addition to the described shooting device, the invention relates to a tool head for a described shooting device, which tool head has a tool cage which is connectable or connected to the tool base body by means of an intermediate plate, wherein the intermediate plate and the tool cage delimit a receiving space for at least one sensor element in sections, wherein the tool head is connectable or connected to the tool base body by at least two fastening means, wherein fastening openings formed for receiving the fastening means are arranged asymmetrically on the intermediate plate and / or the tool base body.The invention further relates to a method for producing a tool head for a shooting device described above, which tool head has a tool cage which can be connected to the tool base body by means of an intermediate plate, wherein the intermediate plate and the tool cage delimit a receiving space for at least one sensor element in sections, wherein the tool head can be connected to the tool base body by at least two fastening means, wherein fastening openings formed for receiving the fastening means are formed asymmetrically on the intermediate plate and / or the tool base body.All advantages, details, embodiments and / or features described with respect to the shooting device can be completely transferred to the tool head and the method for producing a tool head for such a shooting device.The invention is explained on the basis of exemplary embodiments with reference to the figures. The figures are schematic representations and show: FIG. 1 shows a schematic illustration of a shooting device according to an exemplary embodiment in a lateral sectional view; FIG. 2 shows a schematic illustration of an intermediate plate according to an exemplary embodiment in a sectional view in plan view; and FIG. 3 shows a schematic illustration of a tool cage according to an exemplary embodiment in a sectional view in plan view.FIG. 1 shows a shooting device 1, for example a punching device or riveting device. The shooting device 1 has, for example, a tool base body 2 which comprises a feed device 3 through which shooting elements, for example punching elements or riveting elements, not shown in more detail can be guided into a tool head 4, from which the shooting elements can be applied to a component, not shown, for example can be punched or riveted to the latter.The tool head 4 comprises an intermediate plate 5 and a tool cage 6, which are connected to one another and are also connected to the tool base body 2 for mounting the tool head 4 on the tool base body 2, in particular by means of fastening means, in particular screws, which are not shown in more detail.The fastening means are introduced into fastening openings 7, 8. Merely by way of example, first fastening openings 7 and second fastening openings 8 are provided, which are different from one another. Merely by way of example and correspondingly variable, the first fastening openings 7 are provided for mounting the tool head 4 on the tool base body 2 and can be embodied as through-bores in the intermediate plate 5 and the tool cage 6. In other words, fastening means, in particular screws, can be guided through the through-bores of the first fastening openings 7 and screwed into threaded bores, which are not shown and are provided in the tool base body 2, in order to fasten the mounted tool head 4 to the tool base body 2, for example "from below" in the illustration selected in FIG. 1.The second fastening openings 8 are provided for mounting the intermediate plate 5 on the tool cage 6. For example, the second fastening openings 8 in the intermediate plate 5 can be designed as through-bores or stepped bores and the second fastening openings 8, 8' in the tool cage 6 can be designed as threaded bores or vice versa. In other words, the tool head 4 can be mounted by means of the second fastening openings 8, 8', namely by arrangement of the tool cage 6 on the intermediate plate 5, such that the mounted tool head 4 can subsequently be mounted on the tool base body 2, namely by introduction of fastening means into the first fastening openings 7.FIGS. 2, 3 show that the intermediate plate 5 delimits a first subspace 9 and the tool cage 6 delimits a second subspace 10 of a receiving space for receiving a sensor element 11, which is shown partially received in the second subspace 10 in FIG. 3. The sensor element 11 can sense, for example, whether a shot element, for example a punching element or a rivet element, is accommodated in the tool head 4.As shown in FIG. 1, the tool head 4 can only be mounted when the hole patterns of the fastening openings 7, 8 in the intermediate plate 5 and the tool cage 6 are aligned with one another. In the embodiment shown, this is selected such that this applies only to a single orientation, namely the orientation in which the first subspace 9 adjoins the second subspace 10 in the vertical direction, such that the sensor element 11 can be accommodated in a defined manner. In the case of a reverse arrangement, for example when intermediate plate 5 or tool cage 6 is rotated through 180° about the vertical axis or the central axis of feed device 3 shown by way of example, fastening openings 7, 8 are not aligned or the hole pattern of fastening openings 7, 8 is not aligned, so that the fastening means cannot be passed through fastening openings 7, 8.For this purpose, a connecting line 12, 13 is shown in FIGS. 2, 3 for each of the fastening openings 7, 8, which connecting line connects the center points of the fastening openings 7, 8 to the center axis or the center point of the tool head 4 in the corresponding plane. As can be seen, the first fastening openings 7 are present symmetrically, since their center points are arranged point-symmetrically with respect to the center axis of the tool head 4, i.e. of the tool cage 6 or of the intermediate plate 5. One of the second fastening openings 8' is arranged deviating from the symmetrical positioning, namely, as is shown by an arrow, offset in the direction of the central axis or the central plane of the intermediate plate 5 and the tool cage 6.This determines that there is only exactly one mountable orientation in which the fastening means can be passed through and tightened by the fastening openings 7, 8. The attempt to mount the intermediate plate 5 on the tool cage 6 in the reverse orientation fails, since although the first fastening openings 7 can be brought into register even in the reverse orientation, the second fastening openings 8, 8' do not come into register, and thus the intermediate plate 5 and the tool cage 6 cannot be braced against one another. The sensor element 11, which is inserted between the intermediate plate 5 and the tool cage 6, therefore cannot be inadvertently squeezed.The tool head 4, in particular the intermediate plate 5 and the tool cage 6, can therefore be produced by arranging one of the second fastening openings 8 offset in the direction of the central axis or generally by making the intermediate plate 5 and the tool cage 6 asymmetrical with respect to the arrangement of the fastening openings 7, 8.All the advantages, details and features shown in the individual exemplary embodiments can be combined with one another as desired, interchanged and transferred to one another. The shooting device 1, in particular its tool head 4, can be produced by carrying out the method for production described herein. The description can therefore also be applied to this.List of reference characters1 Shooting device 2 Tool base body 3 Feeding device 4 Tool head 5 Intermediate plate 6 Tool cage 7, 8 Fastening opening 9 First subspace 10 Second subspace 11 Sensor element 12, 13 Connecting line
