Description

Technical Field

[0001] The present invention relates to a connecting assembly, a connecting device, a side guiding holding part, a sensor holding part and a covering part holding part of a connecting device for a holding part for mounting a component of a conveying device for transporting piece goods.

[0002] In addition, the present invention respectively relates to a conveying device.

[0003] The present invention also relates to a conveying device. Background Art

[0004] Retention parts are known from the prior art, by means of which side guiding profiles can be fastened to the frame profiles of a conveying device in order to laterally delimit the conveying area and at least temporarily guide the piece goods conveyed in the conveying area. Such retention parts must be constructed robustly in order to withstand the loads during operation of the conveying device and to ensure safety in the event of misuse if necessary. Thus, when a worker touches the installed side guiding profile, the retention part should in particular withstand the weight of the worker in order to perform overhead work, for example, above the conveying area. In order to fasten the side guiding profile to the respective frame profile, the retention part is usually screwed to the frame profile in order to establish a firm and robust connection with the frame profile.

[0005] Such a retention part is known from DE 101 18 566 A1, which can be mounted on the side of the frame profile. For this purpose, the retention part has a connecting screw which acts in cooperation with a fastening groove on the side of the frame profile. The side guiding profile is usually fastened to the frame profile by means of a plurality of such retention parts, wherein the side guiding profile is held on the retention part by means of a chuck.

[0006] The disadvantage here is that additional devices, such as screws, are required to fix the retention part to the frame profile, which makes the installation of the retention part cumbersome. In addition, the retention part is fixed to the side of the frame profile, whereby the subsequent installation of the covering part for the frame profile becomes difficult because the individual sub-parts of the covering part must be arranged between two retention parts. This results in a plurality of joints, in particular, along the side of the frame profile, respectively, between the sub-parts of the covering part and the retention part fastened to the frame profile. In addition, this results in a significant technical extra expense when installing the conveying device, especially since each sub-part of the covering part must be precisely fitted, cut and installed individually. On the other hand, for example, when passing through the conveying device, the laterally protruding screws and screw heads pose an increased risk of damage.

[0007] In addition, a holding part is known from the prior art, by means of which a sensor can be fastened to a frame profile of a conveying device. A holding part is described in EP 0 995 980 A2, which can be fastened to the frame profile by means of a uniaxial connecting device. Here, the holding part has a connecting head, which is inserted into a mating recess on the frame profile and fixed by rotation.

[0008] The disadvantage here is that the recess arranged on the frame profile must have a special and precisely corresponding cross-section to the locking head, which makes the production of the frame profile difficult. The recess is arranged at the selected position, so the sensor position must already be considered during the production of the frame profile. In addition, the uniaxial connecting device is not suitable for fastening side guide profiles.

[0009] A conveying device is known from the prior art, in which a grating for detecting piece goods is provided in the conveying area. Here, when the light beam of the grating is interrupted by the piece goods and thus does not reach the light receiver of the grating, the piece goods are detected.

[0010] Usually, such a conveying device has two opposed side guide profiles that laterally delimit the conveying area, and these side guide profiles are respectively fastened to the frame profile. In order to guide the light beam of the grating into the conveying area, a gap is usually provided between the side guide profile and the frame profile.

[0011] The disadvantage here is that especially piece goods, in particular articles packed in so-called polymer bags, may be clamped in the gap, whereby the transport efficiency of the conveying device is impaired. In addition, damage to the articles may occur.

[0012] To overcome this disadvantage, it is known from the prior art that the side guide profile abuts directly against the frame profile. In order to be able to guide the light beam of the grating into the conveying area, the side guide profile is configured in a segmented manner, and a special connecting piece with an adapted clearance for the sensor is inserted between two successive sub-pieces of the side guide profile. Therefore, the installation of such a conveying device becomes complex and cumbersome. Summary of the Invention

[0013] Therefore, the object of the present invention is to provide a connecting assembly of the type mentioned at the beginning, which can be used universally and can achieve a reduction in the work effort during the installation of the conveying device.

[0014] In addition, the object of the present invention is also to provide a connecting device, a side guide holding part, a sensor holding part, and a cover holding part having such a connecting assembly.

[0015] In addition, the object of the present invention is to describe a conveying device of the type mentioned at the beginning, in which the installation effort can be reduced.

[0016] Furthermore, the object of the present invention is to provide a conveying device of the type described at the beginning, by means of which any piece goods can be transported and reliably detected.

[0017] According to the present invention, in a connecting assembly of the type described at the beginning, the object of the present invention is solved in such a way that the connecting assembly has a base body, the base body comprising a bottom wall, a connecting element and a locking device, wherein the bottom wall provides a mounting surface and the connecting element is arranged protruding from the mounting surface and can engage with a first recess in the recess in the connecting position of the connecting assembly, wherein the connecting element is configured with a mounting rotation axis oriented orthogonally to the mounting surface, the connecting assembly can be rotated from the connecting position to the mounting position about the mounting rotation axis, and wherein the locking device is arranged at a distance from the connecting element, so that the locking device can engage with a second recess in the recess of the mounting leg in the mounting position of the connecting assembly.

[0018] The advantages achieved by the present invention lie firstly in that the connecting assembly can be connected to the mounting leg in a simple manner and method, in particular without screws, and can be used universally, for example for mounting different components of a conveying device, such as side guide profiles, sensors, light reflectors or covers, in particular the retaining part of the bottom cover. Advantageously, for example, the mounting of the retaining part on the mounting leg can be carried out without tools. Here, the connecting element of the connecting assembly can be inserted from above into the first recess in the recess and rotated into the mounting position for fixing, in which the locking device engages in the second recess in the recess. Thus, a simple and lockable plug-in rotary connection is achieved by means of the connecting assembly.

[0019] Here it is preferably provided that the first recess and the second recess or the plurality of recesses are constructed identically.

[0020] Fixing, fastening, etc. "from above" basically means from above the conveying plane in the sense of the present invention.

[0021] The mounting leg can be arranged on the frame profile of the conveying device and / or on the cover. Here, the longitudinal direction of the mounting leg preferably corresponds to the longitudinal direction of the frame profile and / or the conveying device. The longitudinal direction of the mounting leg, the frame profile and / or the conveying device basically extends in the conveying direction of the piece goods. In the curved conveying section of the conveying device, the longitudinal direction of the mounting leg, the frame profile and / or the conveying device can of course also be curved. Alternatively, the longitudinal direction of the mounting leg extends along the wide side or the longitudinal side of the cover.

[0022] Preferably, it is provided that the connecting element is configured to be journal-shaped. Additionally, it can be provided that the locking device is configured to automatically engage into a second recess in the recess. Alternatively, the locking device can be configured such that the locking device can be manually engaged with the second recess in the recess.

[0023] The base body forms a firm base, which is connected to the holding part if necessary or is integrally formed with the holding part.

[0024] For installing a side guide profile or a sensor, for example, it can be provided that the mounting leg is arranged on the frame profile of the conveying device such that the corresponding holding part can be ergonomically advantageously connected to the frame profile from above by means of a connecting assembly. Additionally, during the installation of the conveying device, the work and time consumption are significantly reduced, especially since it is not necessary to tighten the connecting assembly on the frame profile and usually multiple holding parts have to be fixed in the conveying device.

[0025] Since the holding part (such as a side guide holding part or a sensor holding part) is not laterally fastened to the frame profile, it is also possible to arrange an integral side covering of the frame profile (especially a plastic covering) on the frame profile without having to divide the side covering into sub-parts or segments. This additionally simplifies the installation of the conveying device. Furthermore, with the integral side covering or the side covering, the number of joints along the side of the frame profile and / or along the sides of multiple frame profiles of the conveying device is significantly reduced, thus simplifying the cleaning of the conveying device.

[0026] To establish the connection between the connecting device and the mounting leg, first, the connecting assembly is brought into a connection position in which the connecting element is inserted into a first recess in the recess. Thereby, the axis of rotation defined by the connecting element is positioned and oriented. Then the connecting assembly is rotated or pivoted about the axis of rotation, thereby introducing the connecting assembly from the connection position into the mounting position. In the mounting position, the locking device engages with a second recess in the recess. Thereby, the connecting assembly is fixed to prevent unintentional rotation or pivoting back into the connection position.

[0027] To release the connection between the connecting assembly and the mounting leg, the locking device moves out of the second recess in the recess. Now the connecting assembly can be rotated from the mounting position into the connection position, in which the connecting element can move out of the first recess in the recess and, for example, the holding part can be removed from the frame profile.

[0028] Suitably, the base body has

[0029] - a top wall,

[0030] - a first side wall and

[0031] - a second side wall,

[0032] Wherein, the first side wall and the second side wall are arranged opposite to each other and extend from the bottom wall at least to the top wall, and the upper side of the bottom wall faces the top wall and the lower side of the bottom wall provides the mounting surface. Thus, the base body has high stability.

[0033] Preferably, the base body is configured as a hollow body. Thereby, materials can be saved and the weight of the connecting assembly can be reduced. In addition, the base body can provide an inner cavity and, if necessary, a housing. The top wall and the bottom wall can be oriented to extend parallel to each other. The holding part can be arranged to protrude from the upper side of the top wall or to be connected to the top wall. For this purpose, the holding part can be formed on the upper side of the top wall. In addition, it can be provided that the lower side of the bottom wall has a recessed section in which the connecting element is positioned.

[0034] Advantageously, the base body has a plurality of support walls which are arranged between the first side wall and the second side wall and extend from the bottom wall to the top wall. The support walls can be oriented parallel to each other and / or parallel to the first side wall and / or the second side wall. Preferably, the first support wall among the support walls is positioned together with the connecting element in an imaginary line extending orthogonally to the bottom wall.

[0035] In addition, reinforcing ribs can be provided, which are oriented parallel to the support walls and are formed to protrude onto the top wall in the direction towards the bottom wall. If necessary, the reinforcing ribs are positioned together with the spring element in an imaginary line extending orthogonally to the bottom wall. In addition, in addition to or as an alternative to the support walls, a plurality of reinforcing ribs can be provided.

[0036] The support walls and / or the reinforcing ribs increase the bending strength of the top wall, thereby ensuring increased firmness and stability of the connecting assembly. In addition to the bending strength of the top wall, the bending strength of the bottom wall is also increased by the support walls.

[0037] The base body advantageously has a rear wall which extends from the bottom wall at least to the top wall and from the first side wall to the second side wall. Thereby, the base body can be configured to be open on one side, especially closed on the back side and open on the front side. The rear wall can be configured to be curved. Preferably, the rear wall extends from the bottom wall beyond the top wall in order to form a mounting receiving portion for the holding part.

[0038] If the base body is configured as a hollow body, then the bottom wall, the top wall, the opposing side walls and the rear wall define the inner cavity of the hollow body. Suitably, support walls and / or support protrusions are arranged in the inner cavity of the hollow body.

[0039] In a preferred embodiment, the base body has five walls, namely a bottom wall, a top wall, opposing side walls and a rear wall, such that the hollow body is open on one side. Thereby, the base body, especially together with the support walls, can be manufactured by a simple injection molding method.

[0040] Preferably, the base body is constructed of plastic. The base body can be manufactured preferably integrally by an injection molding method or by 3D printing. Thereby, the base body can be manufactured particularly advantageously and simply. In addition, the base body has a small weight.

[0041] Suitably provided that the connecting element includes a journal protruding from the mounting surface, the journal having a hammer-shaped head at the end protruding from the mounting surface, wherein the hammer-shaped head can be guided through the first recess of the mounting leg in the connecting position of the connecting assembly and engages behind the edge region of the first recess of the mounting leg in the mounting position of the connecting assembly.

[0042] Thereby, the fixed connecting element is prevented from being pulled out of the first recess in the recess and the connecting assembly is fixed to the mounting leg substantially by form fit orthogonally to the mounting leg. Here, a slight gap may exist between the mounting leg and the hammer-shaped head to facilitate the pivoting movement between the mounting position and the connecting position. Preferably, the connecting element is arranged anti-rotationally on the bottom wall, in particular on the lower side of the bottom wall.

[0043] Advantageously, the connecting element includes a reinforcing insert.

[0044] Thereby, an improved stability and robustness of the connecting assembly, in particular the connecting element, is achieved. If the connecting assembly is used, for example, to mount the side guide holder of a conveying device, the connecting assembly not only bears the load caused by heavier piece goods during the operation of the conveying device, which may laterally hit the side guide profile and slide along it, but also bears the excessive load that may occur in case of misuse. For example, misuse occurs when a fitter climbs onto the side guide profile and the side guide holder has to transfer the weight of the fitter to the frame profile. The reinforcing insert can be arranged inside the connecting element and / or at least partially surrounded by the connecting element, for example by casting the reinforcing insert during the manufacture of the connecting assembly by an injection molding method. Advantageously, the head of the connecting element includes a reinforcing insert.

[0045] In order to achieve particularly high robustness, the reinforcing insert can be constructed of a metallic material, in particular of steel or aluminum.

[0046] The connecting element suitably includes a recess in which the reinforcing insert is arranged and to which the connecting element is connected. This simplifies the manufacturing method on the one hand. On the other hand, by accommodating different reinforcing inserts in the recess, the robustness of the connecting element can be individually adapted to the corresponding requirements.

[0047] Further advantageously, the recess is arranged on the protruding end of the connecting element, in particular on the head of the connecting element. The reinforcing insert can be bonded or screwed to the connecting element.

[0048] Particularly preferably, the connecting element has a cylindrical screwing-in hole along the longitudinal axis of the connecting element, for example a drilled hole. The screwing-in hole can have an internal thread for a screw for fixing the reinforcing element. Alternatively, the screwing-in hole can be configured with a smooth inner surface or without a thread. Here, the connecting element can be fixed, for example, using a tapping screw that is screwed into the screwing-in hole. Preferably, the screwing-in hole passes through the connecting element and into the first support wall in the support wall.

[0049] Advantageously, the locking device has a locking element that can move perpendicular to the mounting surface, in particular can move out of the base body, in order to engage in the second recess of the recess.

[0050] It can be provided here that the bottom wall preferably has a recess at the lower side, where the locking element can move at least partially, in particular completely, into the recess and / or at least partially out of the recess. The recess can extend through the bottom wall, for example, and is preferably configured as a through-hole, such that the locking element can move at least partially, in particular completely, into the base body and / or at least partially out of the base body. Preferably, the locking element can be moved into the recess or the base body such that the locking element terminates flush with the bottom wall, in particular flush with the lower side of the bottom wall. Thus, the locking element can be at least partially arranged inside the base body or inside the recess in the bottom wall in order to move the connection assembly from the connection position into the installation position, or vice versa. Similarly, the locking element can at least partially protrude from the base body or from the recess in the bottom wall in order to lock the connection assembly in the installation position. It has proven that the locking element is configured as a journal.

[0051] It is preferably provided that the locking element is rotatably supported about a locking rotation axis between a first position and a second position on the base body and has a hammer-shaped head that can be guided through the second recess in the recess in the first position of the locking element and engages behind the edge region of the second recess in the recess in the second position of the locking element.

[0052] Thereby, it is possible to prevent the locking device from moving out of the second recess in the recess. Thus, the connection assembly can be fixed along two axes, namely perpendicular to the mounting leg through the axes of the connecting element and the locking device, in particular similar to the connecting element. This is particularly advantageous when the connection assembly is connected to the mounting leg from below, for example when fastening the covering of a conveying device, in particular the bottom-side covering. It is not mandatory that the first and second positions are fixed. Additionally, it can be provided that the locking element is rotatably supported freely, preferably rotatable 360°.

[0053] Preferably, it can be provided that the locking element is perpendicular to the mounting surface and is movable against the action of a spring force, wherein the locking element can be automatically engaged into the second recess in the recess in the mounting position by means of the spring force.

[0054] Advantageously, the locking device includes a spring element, wherein the locking element is arranged on the spring element. Thus, the locking element can move against the action of the spring force in order to pre-tension the spring element, so that the locking element can automatically be engaged into the second recess in the recess when the spring element is decompressed. Here, it can be provided that the locking element provides a latching element. If necessary, the locking element or the latching element can be rotatably supported on the spring element.

[0055] The spring element can be configured, for example, as a spring arm, and the locking element or the latching element is arranged on the spring arm. Preferably, the latching element is configured as a latching lug, and the latching lug is formed on the spring arm.

[0056] As an alternative to this, the spring element can be arranged in a recess in the bottom wall. The recess is preferably configured cylindrically. Here, the spring element can be connected to the bottom wall at a first end. The locking element can be positioned at a second end of the spring element such that when the spring element is relaxed, the locking element at least partially protrudes from the recess. The locking element cooperates with the spring element such that when the locking element is at least partially pressed into the recess, the spring element is tensioned or compressed.

[0057] For example, the latching element or the locking element can be configured as a journal, wedge-shaped or spherical or configured as a sphere. Preferably, the spring element is configured as a helical spring.

[0058] Suitably, the bottom wall has two gaps extending from a first edge of the bottom wall in a direction towards a second edge of the bottom wall opposite to the first edge and spaced apart from each other, so that the bottom wall is bendable between the gaps in order to provide the spring element. Thus, a section of the bottom wall between the gaps can be bent relative to the rest of the bottom wall and substantially orthogonally to the mounting surface and form the spring element or the spring arm. This enables the locking element or the latching element arranged on the spring element to move, so that the locking element or the latching element can be guided on the mounting leg and can be snapped into the second recess in the recess. Additionally advantageously, the base body is at least partially configured as a hollow body here.

[0059] According to the invention and by means of the above advantages, a further task is solved in such a way that, in a connecting device of the type mentioned at the beginning, the connecting assembly is constructed according to one of the above aspects and the mounting leg has a plurality of recesses spaced apart from one another in the longitudinal direction of the mounting leg, wherein a first recess of the recesses is capable of cooperating with a connecting element of the connecting assembly and a second recess of the recesses is capable of cooperating with a locking element of the connecting assembly. Preferably, the connecting assembly is arranged on the holding part here.

[0060] The connecting device thus comprises a first part, namely the connecting assembly, and a second part, namely the mounting leg, wherein the first and second parts cooperate in order to establish a connection which can in particular be plugged into one another and locked by a rotational movement.

[0061] It is hereby particularly provided that the plurality of recesses spaced apart from one another in the longitudinal direction of the mounting leg are constructed to be identical to one another. This simplifies the manufacturing process of the mounting leg or the frame profile.

[0062] The advantages achieved by means of the invention lie firstly in that the connection can be established in the simple manner and method as described above by means of the connecting device and preferably loosened again without the use of additional tools.

[0063] Advantageously, the mounting leg is arranged on the frame profile of the conveying device.

[0064] The connecting assembly can thus be connected to the frame profile in a simple manner and method in order to, for example, mount a holding part for a side guide profile, a so-called side guide holding part. The connecting assembly is arranged on the holding part here or surrounded by the holding part. In order to mount the side guide profile on the side guide holding part, alternative connecting means can be provided, in particular a form-fitting receptacle, clamping and / or threaded connection etc. of the side guide profile on the side guide holding part.

[0065] Suitably, the mounting leg is arranged on the covering part.

[0066] The connecting assembly can thus be connected to the covering part in a simple manner and method in order to, for example, connect the covering part to a holding part therefor, a so-called covering part holding part. The connecting assembly is arranged on the holding part here or surrounded by the holding part. In order to fasten the holding part to the frame profile, alternative connecting means can be provided.

[0067] By making full use of the aforementioned advantages, a further task is solved, namely that in a side guide holding part of the type mentioned at the beginning, the connecting assembly is constructed according to one of the above aspects.

[0068] In the sense of the present invention, the side guide holding part includes a connecting component, which is equivalent to the connecting component including the side guide holding part. Therefore, these expressions are regarded as similar.

[0069] The advantages achieved by the present invention are especially as described above in that the side guide holding part can be easily accessible, i.e., connected to the mounting leg from above, without additional mounting devices, whereby the side guide profile can be fixed to the frame profile in a simple manner and method.

[0070] The side profile usually has a guiding side and a mounting side, wherein the guiding side points to the conveying area and the mounting side points away from the conveying area. The mounting receiving part is configured to form-locking receive the side guide profile, especially the mounting side of the side guide profile. For this purpose, the mounting receiving part of the side guide holding part and the mounting side of the side guide profile can be constructed with corresponding profiles.

[0071] Preferably, the mounting receiving part is configured such that the side guide profile can be arranged at a vertical distance relative to the frame profile. The vertical distance is oriented orthogonally to the mounting leg and extends between the mounting leg of the frame profile and a (hypothetical) first cutting plane parallel to the mounting leg, which first cutting plane defines the lower edge of the side guide profile. The vertical distance between the frame profile and the side guide profile at least corresponds to the height of the base body of the connecting component, or in other words, corresponds to the distance between the lower side of the bottom wall and the upper side of the top wall. Thereby, an optical access to the conveying area is ensured, which optical access can, for example, enable the detection or detection of the goods transported in the conveying area by means of an optical sensor. In addition, an improved side guidance of the goods can be achieved with a lower side guide profile height. The material usage for the side guide profile can be kept small.

[0072] Advantageously, the mounting receiving part is integrally constructed with the base body of the connecting component. Thereby, the operation of the side guide holding part is simplified and the robustness is increased, since the side guide holding part does not have to be additionally connected to the connecting component, if necessary by means of additional connecting means. In addition, simple manufacturing is achieved.

[0073] Preferably, the mounting receiving part has an opening for receiving the connecting device.

[0074] Therefore, the connecting device can be guided through the opening and the side guide profile can be fastened to the side guide holding part by means of the connecting device. For this purpose, the opening is preferably configured as a through-hole. The connecting device advantageously includes a screw, which passes through the opening with its shank, especially from the outside of the mounting receiving part, and is connected to the side guide profile. Alternatively, the screw can pass through the opening from the inside and be fixed on the outside with a nut. Here, the screw head can be connected to the side guide profile.

[0075] Preferably, it is provided that the connecting device comprises a T-headed screw which can cooperate with the fastening groove of the side guide profile in order to fasten the side guide profile to the side guide holding part. The hammer-shaped screw head of the T-headed screw can be received in the fastening groove of the side guide profile for fastening, wherein the shank of the T-headed screw is guided through the opening of the mounting receiving part and fixed to the mounting receiving part by means of a nut. The fastening groove is suitably arranged on the mounting side of the side guide profile. The fastening groove preferably has fastening tabs on both sides at the open end, so that the fastening groove is configured to surround or engage the hammer-shaped head of the T-headed screw from behind. By tightening the nut, the fastening tabs can be pressed against the mounting receiving part in order to fix the side guide profile.

[0076] In the case of using the advantages described for the connecting assembly or connecting device, a further task is solved in that, in a sensor holding part of the type described at the beginning, the sensor holding part has a connecting assembly according to any one of the foregoing aspects.

[0077] In the sense of the present invention, the sensor holding part comprises a connecting assembly which is equivalent to the connecting assembly comprising the sensor holding part. These expressions are therefore regarded as similar.

[0078] Suitably, the outer housing has a bottom wall and a top wall. In addition, a first side wall and a second side wall can be provided, which are arranged opposite one another and extend from the bottom wall to the top wall respectively. In addition, a rear wall can be present, which extends from the first side wall to the second side wall and from the bottom wall to the top wall. It can be provided here that the upper side of the bottom wall faces the top wall and the lower side of the bottom wall provides the mounting surface. The top wall, bottom wall, side walls and / or rear wall are preferably constructed integrally.

[0079] Advantageously, the outer housing is constructed such that the emitted light beam can be guided out of the outer housing and the reflected light beam can be guided into the outer housing. For this purpose, the outer housing can be constructed open on one side. This can be achieved in that the outer housing does not have a wall on the side facing the conveying area after being mounted on the frame profile of the conveying device. Alternatively, the outer housing can have a fourth side wall which has at least one opening, so that the sensor, in particular the light source and the light receiver, is optically accessible.

[0080] In an alternative embodiment, the outer housing can be constructed in a grid-like manner as a support or side wall, bottom wall and / or top wall.

[0081] The inner housing is arranged within the outer housing and is used to accommodate sensors. Thus, the sensor holder can be used flexibly because different sensors can be accommodated in the inner housing. Therefore, for example, the inner housing can be adapted to any sensor without having to adapt the outer housing, the connection between the inner housing and the outer housing, and / or the connection components.

[0082] In order to detect or sense, for example, the piece goods transported by the conveying device, it is advantageous that the sensor holder includes sensors. The sensors are preferably configured as optical sensors, including a light source and a light receiver. Here, the sensors can be configured, for example, to sense the piece goods or to detect identification marks, such as barcodes or QR codes.

[0083] Advantageously, the sensors are arranged such that the light beam emitted by the light source passes through the conveying area. For this purpose, it can be provided that the sensor holder is configured or can be fastened to the frame profile such that the sensors are arranged between the mounting leg and the aforementioned first cutting plane. For this purpose, the height of the outer housing preferably corresponds to the height of the base body of the connection component of the side guide holder or the orthogonal distance between the corresponding bottom wall and top wall.

[0084] Preferably, it is provided that the base body of the connection component forms the outer housing. Thus, the sensor holder including the connection component or the connection component including the sensor holder can be manufactured in a simple manner and method.

[0085] The height of the base body of the sensor holder, i.e., the orthogonal distance between the bottom wall and the top wall, is preferably less than or equal to the aforementioned vertical distance between the frame profile and the side guide profile. Thus, additional advantages can be seen, namely that the sensor holder can be fastened to the frame profile of the conveying device even if the side guide profile has already been installed. Similarly, the sensor holder can be loosened from the frame profile without having to remove the side guide profile beforehand. In addition, it is also possible to achieve, for example, a simple replacement of a faulty sensor, which simplifies the maintenance of the conveying device.

[0086] Suitably, the inner housing can be pivotally supported on the outer housing, wherein the inclination of the inner housing can be adjusted by means of an adjusting device. Thereby, the adjustability of the angle enclosed by the emitted light beam and the conveying plane can be achieved. For pivotally supporting, the outer housing can respectively have bolt receiving portions in the first side wall and the second side wall, such as circular or oval openings and / or recesses, in particular drill holes. The inner housing can have two cylindrical protrusions or bolts corresponding to the bolt receiving portions, and the protrusions or bolts are arranged in a line with each other on both sides on or formed on the inner housing. These bolts are configured such that they can be fitted into the corresponding bolt receiving portions. Thus, the bolts define the pivot axis of the inner housing, and this pivot axis is oriented substantially parallel to the bottom wall and the top wall of the outer housing. Preferably, the inner housing is detachably fastened in the outer housing. For this purpose, mounting notches can be respectively provided on the inner sides of the first side wall and the second side wall, and the mounting notches lead from the edges of the side walls to the bolt receiving portions, so as to guide the screws from the notches into the bolt receiving portions.

[0087] The adjusting device preferably includes an adjusting screw and a toothing that cooperates with the adjusting screw, and the toothing is arranged on the inner housing, in particular formed on the inner housing. Preferably, the adjusting screw is configured as a threaded pin. Advantageously, the toothing is configured to be bent around the pivot axis of the inner housing, so that during the pivoting of the inner housing, it is ensured that the thread of the adjusting screw is continuously fitted into the toothing of the inner housing. In order to construct a sensor holding part with a small height, it can be provided that the adjusting screw is oriented orthogonally to the bottom wall and the top wall of the outer housing and the toothing is arranged on the rear wall of the inner housing. Preferably, the bottom wall and / or the top wall have operating openings through which the adjusting screw can be operated, for example, by means of a screwdriver.

[0088] Alternatively, the adjusting screw can be oriented parallel to the bottom wall and the top wall of the outer housing and the toothing can be arranged on the bottom wall or the top wall of the inner housing. Thereby, the sensor holding part can be constructed with a small depth. Here, the rear wall of the outer housing can have an operating opening through which the adjusting screw can be operated, for example, by means of a screwdriver.

[0089] The connecting element of the connecting assembly advantageously has a cable channel through which the cables of the sensor can be led out of the housing. Thereby, power supply for the sensor, in particular by an external power supply, or data exchange between the sensor and a data processing device can be achieved. The cables of the sensor, such as current cables and / or data cables, can be guided through the connecting element via the cable channel and thus through the first recess in the recess. Here, the cables of the sensor can have a single cable or be configured as a cable bundle having multiple cables. Preferably, the cable channel is configured cylindrically and extends parallel to the longitudinal axis of the connecting element, preferably from the hammer-shaped head of the connecting element through the bottom wall into the housing. The side walls of the cylindrical channel can be open or have slits parallel to the longitudinal axis of the channel over the entire length of the channel, such that the cable channel has a substantially C-shaped cross-section. Thus, the cable can be pressed into the cable channel laterally through the slit.

[0090] In view of the foregoing advantages, this further task is solved in such a way that, in a cover holding part of the type described at the beginning, the connecting assembly is configured according to the foregoing aspects.

[0091] With such a cover holding part, the cover of the conveying device, in particular the bottom cover or the conveying device protective cover, can be fastened to the frame profile of the conveying device. For this purpose, the cover is fastened to the first frame profile of the conveying device on the one hand and to the second frame profile of the conveying device on the other hand by means of a plurality of cover holding parts.

[0092] Preferably, the mounting receptacle is integrally formed with the base body of the connecting assembly. Thereby, a cover holding part that can be easily operated is provided, which is first connected to the cover and can then be fastened to the frame profile of the conveying device with less manual operation.

[0093] Suitably, the mounting receptacle is connected to the base body of the connecting assembly by a hinge connection, such that the mounting receptacle and the base body of the connecting assembly can pivot relative to each other. Thereby, the cover can be pivotally fastened to the frame profile of the conveying device. It can be provided here that the cover is first connected to the first frame profile of the conveying device in a first position by means of a plurality of pivotable cover holding parts along a first edge of the cover and is then pivoted into a second position, in which the cover is connected to the second frame profile of the conveying device along a second edge of the cover by means of a plurality of pivotable or integral cover holding parts.

[0094] Advantageously, the mounting receptacle has an opening for receiving the connecting device. The connecting device can thus be guided through the opening and fastened to the frame profile. The aspects previously described for the connection between the side guide holder and the side guide profile and for the connecting device of the side guide holder apply analogously to the connection between the cover receptacle and the frame profile or to the connecting device of the cover receptacle.

[0095] It is also particularly preferably provided that the connecting device comprises a T-head screw which can cooperate with a fastening groove of the frame profile in order to fasten the cover holding part to the frame profile.

[0096] In the case of utilizing the above advantages, it is preferably provided that the locking device of the connecting assembly has a locking element which can move perpendicular to the mounting surface in order to engage in a second recess in the recess, and / or the locking element is supported on the base body in such a way that it can be reversibly rotated from a first position to a second position about a locking axis of rotation and has a hammer-shaped head which can be guided through the second recess in the recess in the first position of the locking element and engages behind an edge region of the second recess in the recess in the second position of the locking element.

[0097] Another task is solved by utilizing the above advantages in such a way that, in a conveying device of the type described at the beginning, at least one of the side guide holders in the side guide holders has a connecting assembly according to any one of the preceding aspects and is connected to a corresponding frame profile in the frame profiles by a connecting device according to any one of the preceding aspects.

[0098] The advantages achieved by the present invention lie in particular in that the conveying device can be established in a simple manner and method, wherein the side guide holder can be connected to the mounting leg of the frame profile without screwing.

[0099] The conveying plane on which the piece goods can be transported can be defined by at least one conveying element. For example, the conveying device can be configured as a belt conveyor, wherein an endless conveyor belt provides the conveying element, and the conveying plane is defined by the conveyor belt. Alternatively, the conveying device can be configured as a roller conveyor, wherein a plurality of conveying elements, in particular conveying rollers, are provided, and the conveying plane is defined by the conveying elements.

[0100] In such a conveying device, the first side guide profile and the second side guide profile form the lateral delimitation of a conveying area in which piece goods can be conveyed. The conveying area is delimited downward by the conveying plane. The piece goods are transported on the conveying plane.

[0101] Suitably, at least one of the side guide holders is configured according to one of the foregoing aspects. Additionally, additional alternative side guide holders can be used.

[0102] Advantageously, the frame profiles each include profile legs oriented orthogonally to the conveying plane, where the profile legs have a first side facing the conveying plane and a second side facing away from the conveying plane, and the mounting legs are arranged on the profile legs protruding from the second side and are oriented parallel to the conveying plane. The mounting legs are preferably arranged in a plane with the conveying plane and / or arranged and oriented parallel to the conveying plane. The frame profiles preferably include additional legs arranged parallel to the mounting legs, which additional legs are arranged on the profile legs protruding from the second side, such that the frame profiles have a substantially C-shaped cross-section. Additionally, the frame profiles can have removable side covers that extend between the mounting legs and the additional legs and are positioned spaced apart from the profile legs, thereby providing an inner cavity defined by the profile legs, the mounting legs, the additional legs, and the side covers. In this inner cavity, for example, cables, in particular current or data cables of sensors, can be guided. Particularly preferably, the cables of the sensors are guided through the cable channels of the sensor holders through the first recess in the recess into the inner cavity of the frame profile.

[0103] Advantageously, the profile legs have a plurality of mounting openings. On the mounting openings among the mounting openings, for example, conveying elements or components such as junction boxes for actuators and / or sensors, data processing devices, power supply units for electrical components, etc. can be mounted. The conveying elements, in particular conveying rollers, can be supported by roller shafts in the opposing mounting openings of the frame profile. Alternatively or additionally, one of the mounting openings can be used for threading cables, such that the cables can be guided from the first side of the profile leg to the second side of the profile leg, in particular into the inner cavity of the profile leg.

[0104] Preferably, the side guide profiles each have fastening grooves for receiving the connecting devices of the side guide holders. Thus, the side guide profiles can be fastened to the side guide holders in a simple manner and method. Here, the fastening grooves can be configured as described previously with respect to the side guide holders.

[0105] For monitoring the transportation process, it can be stipulated that at least one sensor is fastened to one of the frame profiles by means of a sensor holder according to one of the above aspects. Preferably, the sensor is connected to a control unit, which controls the drive of the conveying element based on the sensor signal, for example, changes the conveying speed of the conveying element of the conveying device, so as to stop the piece goods during the conveying movement or convey the piece goods at a changed conveying speed in the conveying section. In order to detect the presence of piece goods in a determined conveying section, the conveying device preferably has a grating, and the grating includes a sensor. The grating can be configured as a unidirectional grating, which includes a light source or a light emitter and a light receiver positioned on opposite sides of the conveying area. Alternatively, the grating can be configured as a reflection grating, wherein the sensor includes a light source and a light receiver arranged in a common housing, and the grating includes a light reflector, which is positioned on the side of the conveying area opposite to the sensor.

[0106] This further task is solved by means of a conveying device of the type described at the beginning, wherein at least one of the covering part holders has a connection assembly according to one of the foregoing aspects and can be connected to the covering part via a connecting device according to one of the foregoing aspects, in which connecting device the mounting legs are arranged on the covering part, and wherein a first edge section and a second edge section of the covering part are respectively configured as mounting legs.

[0107] Preferably, the covering part is configured as a bottom-side covering part and is mounted on the underside of the conveying device. The bottom-side covering part serves as a protective part to prevent being inserted into the conveying device from below. In addition, the covering part can be lined with a pad to attenuate the sound or noise of the conveying device.

[0108] By means of the connecting device or the holder having a connection assembly according to the present invention, the covering part can be connected to the frame profile of the conveying device in a simple manner and method. In particular, it can be stipulated here that the covering part holder is first connected to the covering part by means of the connection assembly and then connected to the frame profile by means of a connecting device, preferably a T-head screw.

[0109] In the case of utilizing the foregoing advantages, at least one covering part holder is configured according to one of the foregoing aspects.

[0110] The frame profiles respectively suitably have covering legs oriented parallel to the conveying plane, and the covering legs have fastening grooves. The covering legs can be substantially corresponding to the other legs described previously and extend parallel to the mounting legs of the frame profile. The fastening grooves are configured similar to the fastening grooves of the side guiding profiles, so that the connecting devices of the covering part holder, in particular T-head screws, can be received in the fastening grooves.

[0111] Advantageously, the conveying device is constructed according to one of the aspects described previously.

[0112] According to the invention, a further task is solved in that, in a conveying device of the type described at the beginning, the first side guide profile has a first through-hole through which the emitted light beam can be guided into the conveying area and which provides a sensor-side orifice plate for the emitted light beam.

[0113] Thus, the sensor can be positioned behind the side guide profile or on the side of the side guide profile facing away from the conveying area, i.e., on the mounting side, wherein the emitted light beam is guided into the conveying area through the through-hole. Thus, the advantage achieved with the present invention can be that the sensor can be positioned very space-savingly. In addition, the sensor is arranged on the side of the first side guide profile or the second side guide profile facing away from the conveying area located between the first side guide profile and the second side guide profile and can be mounted in such a way that the side guide profile is not interrupted. Thereby, it is possible to mount the first or second side guide profile at a relatively small vertical distance relative to the frame profile, preferably directly adjacent to the frame profile, so that the conveying device is suitable for transporting any piece goods, in particular articles packaged in plastic bags or polymer bags. The first side guide profile and / or the second side guide profile can have a skirt for this purpose, which increases or extends the guiding surface of the side guide profile facing the conveying area below the conveying plane and closes the gap between the side guide profile and the frame profile. Here, the skirt can include an orifice plate. With the orifice plate, the emission cone angle of the emitted light beam is restricted, thereby enabling the sensitivity of the sensor to be increased.

[0114] In this way, a significantly less expensive sensor can be used, the light source or light emitter of which typically provides a particularly divergent light beam, since the measurement or detection inaccuracies caused by the divergent light beam can be substantially compensated for by the restricted emission cone angle.

[0115] One or more sensors can be mounted on the first frame profile of the conveying device by means of a first embodiment of a sensor holder according to one of the aspects described above. Alternatively, one or more sensors can be mounted by means of a second embodiment of a sensor holder which can be fastened laterally to one of the frame profiles or can be screwed laterally to the frame profile.

[0116] Alternatively, one or more sensors can be fastened to the first side guide profile by means of a third embodiment of the sensor holder. For this purpose, the sensor holder has fastening means, in particular clamping means, which cooperate with the fastening groove of the side guide profile in order to fasten the sensor holder at the side guide profile. The fastening means can be constructed substantially analogously to the mounting section of the side guide holder described previously. In addition, the sensor holder can have an outer housing, an inner housing and, if necessary, adjusting means, which are constructed substantially analogously to the outer housing, inner housing and, if necessary, adjusting means of the sensor holder described previously.

[0117] Preferably, the conveying device has a grating which comprises a sensor and a light reflector corresponding to the sensor, wherein the sensor has a light receiver and the light reflector is positioned on the side of the conveying area opposite the sensor such that the emitted light beam can be reflected on the light reflector and the reflected light beam can be guided from the light reflector to the light receiver. The sensor is thus constructed as a reflection grating. Thereby, the light source and the light receiver can be positioned on the same side of the conveying area, in particular in a common housing. The advantage thus results that only the wiring of the sensor has to be mounted on the first frame profile, while passive elements, namely light reflectors, are arranged on the second frame profile. Here, the light beam is guided substantially as the emitted light beam through the conveying area from the sensor to the light reflector and as the reflected light beam through the conveying area back to the sensor. Here, the light reflector can be fastened to the second frame profile or to the second side guide profile.

[0118] The piece goods transported past the sensor in the conveying direction interrupt the light beam. This interruption is detected by the sensor and converted into an electrical signal. It is thus possible to detect the presence of piece goods in a specific section of the conveying device. By means of the light reflector, the path length of the light beam is substantially doubled and the light beam is guided through the conveying area twice. Thereby, the probability that the light beam is guided past the piece goods to be detected by means of reflection is reduced and the sensitivity of the sensor or the grating is increased.

[0119] The second side guide profile suitably has a second through-hole through which the emitted light beam can be guided to the light reflector and the reflected light beam can be guided into the conveying area, and the second through-hole provides a reflector-side aperture plate for the emitted light beam and / or the reflected light beam. Thus, the light reflector can be arranged analogously to the sensor or also on the side of the first or second side guide profile facing away from the conveying area between the first side guide profile and the second side guide profile. By means of the reflector-side aperture plate, it is also possible to limit the light cone angle of the emitted light beam and / or the reflected light beam incident on the reflector, thereby further increasing the sensitivity of the sensor.

[0120] Advantageously, the sensor can be adjusted relative to the first through-hole via an adjusting device such that the first through-hole blocks a part of the emitted light beam. Thereby, the emitted light beam and / or the light cone angle of the emitted light beam can be targeted restricted or trimmed, thereby further improving the sensitivity of the sensor.

[0121] Similar to the sensor and in case of utilizing the above advantages, it can be provided that the light reflector can be adjusted relative to the second through-hole via a further adjusting device such that the second through-hole blocks a part of the reflected light beam.

[0122] It has been confirmed that the optical axis of the emitted light beam extends offset and / or inclined relative to the central axis of the first through-hole.

[0123] Suitably provided that the optical axis of the reflected light beam extends offset and / or inclined relative to the central axis of the second through-hole. Thereby, the edge region of the emitted light beam and / or the reflected light beam can be blocked and thus the light cone is restricted, thereby improving the sensitivity of the sensor.

[0124] Advantageously, the conveying device is configured according to one of the foregoing aspects. Description of the Drawings

[0146] It must first be determined that identical parts in different described embodiments are provided with identical reference signs or identical component names, where the disclosure contained throughout the specification can be transferred in meaning to identical parts with identical reference signs or identical component names. The positional descriptions chosen in the specification, such as upper, lower, side, etc., also refer to the directly described and illustrated drawings and are transferred in meaning to new positions when the position changes.

[0147] Figure 1 A perspective view showing a section of a conveying device 1 for piece goods 2, the conveying device comprising two frame profiles 3a, 3b, two side guide profiles 4a, 4b and a plurality of conveying elements 5.

[0148] In the illustrated example, the first frame profile 3a and the second frame profile 3b extend parallel to each other at a distance from each other in the conveying direction of the piece goods 2. The conveying elements 5 are arranged between the first frame profile 3a and the second frame profile 3b and define a conveying plane.

[0149] Here, the conveying element 5 is configured as a conveying roller. Alternatively, it can be provided, for example, that the conveying element 5 is configured as a conveyor belt or that there is provided a conveying element 5 which is configured as a conveyor belt. The conveyor belt can also be guided around the conveying roller, so that the conveying element 5 is formed by the conveyor belt.

[0150] The piece goods 2 are transported on the conveying plane FE or in a conveying area which is laterally limited by the side guide profiles 4a, 4b or by the mutually facing inner sides or guide sides of the side guide profiles 4a, 4b and is limited downwards by the conveying plane FE.

[0151] In order to laterally delimit the conveying area, the first side guide profile 4a and the second side guide profile 4b also extend parallel to each other at a distance from each other and in the conveying direction of the piece goods 2. The side guide profiles 4a, 4b are respectively fastened to the corresponding frame profiles 3a, 3b by a plurality of side guide retaining parts 6.

[0152] Furthermore, the side guide profiles 4a, 4b each have a guide side and a mounting side. In the illustrated conveying device 1, the side guide profiles 4a, 4b are arranged such that the guide sides of the side guide profiles face each other or are directed towards the conveying area. The mounting sides of the first side guide profile 4a and the second side guide profile 4b face away from each other or away from the conveying area. In addition, the side guide profiles 4a, 4b are respectively connected to the side guide retaining parts 6 on the mounting side.

[0153] Furthermore, the frame profiles 3a, 3b each have mounting legs 7, which mounting legs include a plurality of recesses 8 spaced apart from one another. In order to fasten the side guide holders 6 to the frame profiles 3a, 3b, the side guide holders are each configured such that the side guide holder 6 can be snapped into the recesses 8 in the mounting legs 7.

[0154] The frame profiles 3a, 3b substantially have a C-shaped cross-section, wherein side coverings 9 are provided for closing or covering the open side of the C-shaped cross-section. Thus, an inner cavity of the frame profiles 3a, 3b delimited by the frame profiles 3a, 3b and the side coverings 9 is provided. In Figure 1 FIG. shows a first frame profile 3a with a side covering 9 and a second frame profile 3b without a side covering 9.

[0155] In order to detect the piece goods 2, the conveying device 1 has a sensor 10, which is fastened to the second frame profile 3b by means of a sensor holder 11. The sensor holder 11 is mounted here similar to the side guide holder 6, such that the sensor holder can be snapped into the recesses 8 in the mounting legs 7.

[0156] In Figure 2 FIG. shows a perspective view of the side guide holder 6, which side guide holder includes a connecting assembly 12 and a mounting receptacle 13. The connecting assembly 12 is arranged on the underside of the side guide holder 6 and cooperates with the mounting leg 7, in particular with two adjacent recesses 8, to form a connecting device.

[0157] It is provided here that the connecting assembly 12 is arranged on the underside of the side guide holder 6 and has a base body. The base body includes a bottom wall 14, a top wall 15, a rear wall, and two side walls 16. The first side wall 16 and the second side wall 16 are positioned at two opposite ends of the bottom wall 14 and both extend between the bottom wall 14 and the top wall 15. The rear wall extends from the first side wall 16 to the second side wall 16 and from the bottom wall 14 to the top wall 15. Furthermore, a plurality of support walls 17 are provided, which support walls extend from the bottom wall 14 to the top wall 15 parallel to the side walls.

[0158] On the side or underside of the bottom wall 14 facing away from the top wall 15, a connecting element 18 and a locking device are arranged. The connecting element 18 and the locking device cooperate with two adjacent recesses 8 in the mounting leg 7 in order to establish a connection, such that the connecting assembly 12 and the mounting leg 7 form a connecting device.

[0159] The connecting element 18 includes a journal having a hammer-shaped head at the end protruding from the bottom wall 14. In order to form the hammer-shaped head, the protruding end is configured with a side recess. The journal is formed onto the bottom wall 14.

[0160] Furthermore, the connecting element 18 may include a reinforcing element 19 disposed in a recess on the protruding end of the connecting element 18. The reinforcing element 19 may be configured as a plate, especially made of steel or aluminum. For fixation, the reinforcing element 19 may be screwed to the connecting element 18.

[0161] According to this embodiment, the locking device includes a spring element 20 and a locking element 21, which is disposed, preferably formed, on the spring element 20. The spring element 20 may be configured as a spring tongue. Thus, the connecting assembly 12 and the mounting leg 7 form a lockable connecting device.

[0162] In the illustrated example, the locking element 21 is configured as a latching lug. To form the spring element 20, the bottom wall 14 has two slits starting from the edge of the bottom wall 14, such that the bottom wall 14 is bendable between these slits. Thus, the section of the bottom wall 14 between the slits forms the spring element 20. Here, the slits extend parallel to each other or mirror each other around a symmetry axis, such that the spring element 20 or the slits and the imaginary connecting line between the ends of the slits form a rectangle or an isosceles trapezoid.

[0163] It should be noted that the connecting assembly 12 shown in Figure 2 may be arranged on the side guide holder 6, or equally on a holder for other components and members of the conveying device 1 or may be part of such a holder.

[0164] The mounting receptacle 13 is arranged on the side of the top wall 15 facing away from the bottom wall 14 or on the upper side. Furthermore, the mounting receptacle 13 is configured to form - fitly receive the side guide profiles 4a, 4b. For this purpose, the mounting receptacle 13 has a profile corresponding to the mounting sides of the side guide profiles 4a, 4b.

[0165] To fasten the side guide profiles 4a, 4b to the mounting receptacle 13 or the side guide holder 6, the mounting receptacle 13 has a connecting device 22, which includes T - head screws in the illustrated example.

[0166] To increase the shape stability or flexural rigidity of the side guide holder 6, the illustrated mounting receptacle 13 has a plurality of support ribs 23, which are arranged substantially orthogonally to the top wall 15. The support ribs 23 are not absolutely necessary. Thus, the mounting receptacle 13 can also be configured as a solid body, for example.

[0167] In Figure 3a and Figure 3b the process of establishing a connection between the connecting assembly 12 and the mounting leg 7 is shown in a bottom view.

[0168] The recess 8 of the mounting leg 7 is configured in the illustrated example as a rectangular elongate recess or as a slot with rounded corners. The circumferential shape of the recess 8 substantially corresponds to the circumferential shape of the hammer-shaped head.

[0169] To fasten the connecting assembly 12 to the mounting leg 7, the connecting assembly 12 is first brought into the connecting position 24. In the connecting position 24, the connecting element 18 is in the same orientation as the first recess 8 in the recess 8. Thereby, the hammer-shaped head of the connecting element 18 can be guided through the first recess 8. This is shown in Figure 3a Now, the connecting element 18 inserted into the first recess 8 defines a rotational axis about which the connecting assembly 12 can rotate or pivot into the mounting position 25. The rotational axis is oriented perpendicular to the mounting leg 7. As can be seen in Figure 3a and Figure 3b the recesses 8, in particular the first and second recesses 8 in the recess 8, are configured identically.

[0170] Next, the connecting assembly 12 can be rotated into the mounting position 25 about the rotational axis by a specific rotational angle α, in particular by at least 30°, preferably by an angle in the range from 45° to 90°, particularly preferably by approximately 60°. Figure 3b The connecting assembly 12 in the mounting position 25 is shown.

[0171] In the mounting position 25, the hammer-shaped head of the connecting element 18 engages the mounting leg 7 from behind in the edge region of the first recess 8. Thus, the connecting element 18 is fixed in the first recess 8 orthogonally to the mounting leg 7 against movement out of the first recess.

[0172] During the rotation of the connecting assembly 12 from the connecting position 24 into the mounting position 25, the locking element 21 and the mounting leg 7 cooperate such that the locking element 21 and the spring element 20 move orthogonally to the mounting leg 7 and in the direction of the top wall 15 of the base body or upwards against the action of the spring force. Here, the spring element 20 is pre-tensioned.

[0173] In the mounting position 25, the locking element 21 is positioned above or in line with the second recess 8 in the recess 8 such that the locking element 21 automatically engages and snaps into the second recess 8 when the spring element 20 is decompressed. Thereby, the connecting assembly 12 is fixed against unintentional rotation about the rotational axis, whereby the connecting device is locked.

[0174] In an alternative embodiment, it can be provided that the locking element 21 is first arranged flush with or recessed from the bottom wall 14 and does not automatically snap in in the mounting position 25, but rather has to be moved or pressed through the second recess 8.

[0175] To release the connection, the locking element 21 first moves out of the second recess 8. Then, the connection assembly 12 can be rotated from the installation position 25 into the connection position 24, in which the connection element 18 can be pulled out of the first recess 8 in the recess 8.

[0176] The orientation of the connection position 24 and the installation position 25 and the rotation angle α are indicated by dash-dotted lines respectively in Figure 3a and Figure 3b respectively.

[0177] In Figure 4a and Figure 4b a top view shows the process for establishing the connection for the side guide holder 6 generally shown for the connection assembly 12 in Figure 3a and Figure 3b Here, the side guide holder 6 moves from the connection position 24 ( Figure 4a ) to the installation position 25 ( Figure 4b ). The side guide holder 6 is constructed as shown in Figure 2 , wherein the connecting device 22 of the side guide holder 6 is visible in Figure 4a and Figure 4b .

[0178] Figure 5 shows a cross-section through the conveying device 1 along the line V-V in Figure 1 . Here, the second side guide profile 4b is fastened to the second frame profile 3b by the side guide holder 6. Of course, the first side guide profile 4a can be fastened to the first frame profile 3a by a further side guide holder 6 in a similar manner. The conveying plane FE is oriented orthogonally to the drawing plane.

[0179] Furthermore, the frame profiles 3a, 3b include profile legs 26 on which the conveying elements 5 are rotatably supported by means of rollers. The mounting legs 7 of the frame profiles 3a, 3b project orthogonally to the profile legs 26 and are arranged away from the conveying area or the conveying elements 5. In addition, the frame profiles 3a, 3b include further legs which are arranged parallel to the mounting legs 7 at the end of the profile legs 26 opposite to the mounting legs 7.

[0180] Thus, the mounting legs 7, the profile legs 26 and the further legs basically form a C-shaped cross-section of the frame profiles 3a, 3b. In addition, the further legs have fastening grooves 27a pointing downwards or away from the mounting legs 7.

[0181] The side guide holder 6 can be fastened to the mounting legs 7 of the frame profiles 3a, 3b by the connection assembly 12, in particular as Figures 3a to 4b shown.

[0182] In Figure 5The side guide holder 6 is shown in a cross section through the connecting element 18 and the first support wall 17, which is arranged in line with the connecting element 18, so that the fastening screws for the strengthening element 19 can be seen. The fastening screws extend along the longitudinal axis of the connecting element 18. It is hereby specified that the screws pass through the connecting element 18 and through the bottom wall 14 into the first support wall 17. For this purpose, the connecting element 18 and the first support wall 17 have cylindrical bores with internal threads for the fastening screws.

[0183] The side guide profiles 4a, 4b have fastening grooves 27b on the mounting side, which cooperate with the connecting devices 22, in particular with T-head screws, in order to fasten the side guide profiles 4a, 4b to the side guide holder 6.

[0184] In Figure 6 a side view of the conveying device 1 is shown, in which the side guide profile 4b is fastened to the frame profile 3b by means of the side guide holder 6. This construction is also possible for the first side guide profile 4a on the first frame profile 3a and for the second side guide profile 4b on the second frame profile 3b, as Figure 1 shown. The side cover 9 is also not shown in this illustration.

[0185] The profile legs 26 of the frame profiles 3a, 3b include a plurality of mounting openings 28. It is specified that the conveying elements 5 are supported in such mounting openings 28, as in Figure 5 shown. For this purpose, the roller shafts of the conveying elements 5 are inserted into the mutually opposing mounting openings 28 of the first frame profile 3a and the second frame profile 3b.

[0186] Figure 7 The sensor holder 11 is shown in a perspective view, in which the connecting assembly 12 is arranged on the lower side of the sensor holder 11. Thus, the sensor holder 11 can be fixed to the mounting legs 7 of the frame profiles 3a, 3b by means of the connecting assembly 12. As described above and as shown in Figure 3a and Figure 3b the fastening process takes place.

[0187] It is hereby specified that the base body of the connecting assembly 12 provides the outer housing 29 of the sensor holder 11. An inner housing 30 is arranged inside the outer housing 29, in which the sensor 10 is located.

[0188] According to this embodiment, the inner housing 30 is pivotally supported on the outer housing 29. For this purpose, the first side wall 16 and the second side wall 16 of the connecting assembly 12 or the outer housing 29 respectively have bolt receiving parts 31. The bolt receiving parts 31 include through holes for receiving bolts and guide recesses, in which the bolts can be guided to the through holes.

[0189] It is hereby stipulated that bolts are respectively formed on the opposing side walls of the inner housing 30, and the bolts are respectively fitted into bolt receiving portions 31. The bolts are oriented in a line with each other such that the bolts define a pivot axis of the inner housing 30, and this pivot axis is oriented parallel to the bottom wall 14.

[0190] In addition, the connecting element 18 of the connecting assembly 12 has a cable passage through which the sensor cable 32 can be led out from the outer housing 29. The cable passage is constructed to extend through the connecting element 18 and through the bottom wall 14 in a cylindrical shape. In order to be able to laterally press the sensor cable 32 into the cable passage, the cable passage is laterally open or is constructed in a C-shaped cross-section. Since the cable passage extends through the connecting element 18, it is possible for the sensor cable 32 to be guided through the first recess 8 in the recess 8 into the inner cavity of the frame profiles 3a, 3b.

[0191] Since the load on the sensor holder 11 is less than the load on the side guide holder 6, it is not necessary for the base body to have multiple support walls and / or for the connecting element 18 to have a strengthening element 19.

[0192] In order to adjust the inclination of the inner housing 30 and thus the sensor 10 accommodated therein relative to the conveying plane FE, the sensor holder 11 has an adjusting device which can be accessed and manipulated through a manipulation opening 33 in the top wall 15 and / or in the bottom wall 14.

[0193] Figure 8 Shows a cross-section through the sensor holder 11 along Figure 7 the line VIII-VIII shown in, in which the adjusting device located within the outer housing 29 is visible.

[0194] The adjusting device includes an adjusting screw 34 and a toothing 35 which cooperates with the adjusting screw and is arranged on the inner housing 30. In the example shown, the adjusting screw 34 is oriented orthogonally to the bottom wall 14 and the toothing 35 is bent around the pivot axis of the inner housing 30. By manipulating or rotating the adjusting screw 34, the inner housing 30 and thus the sensor 10 can be pivoted about the pivot axis, as indicated by the double arrow. The adjusting screw 34 can be manipulated, for example, with a screwdriver through the manipulation opening 33 in the top wall 15.

[0195] Figure 9 Shows a cross-section through the conveying device 1 along Figure 1 the line IX-IX shown in. Here, the sensor holder 11 is fastened to the mounting leg 7 of the second frame profile 3b, so that the outer housing 29 is basically positioned between the second frame profile 3b and the second side guide profile 4b. Of course, the sensor holder 11 can be fastened to the first frame profile 3a in a similar manner.

[0196] Here, the side guide profiles 4a, 4b are arranged identically to those in Figure 5 such that a perpendicular distance is provided between the mounting leg 7 and the lower edge of the side guide profiles 4a, 4b or the tangent plane passing through the base of the side guide profiles 4a, 4b. The perpendicular distance enables the sensor 10 to be optically connected to the conveying area.

[0197] Figure 10a A perspective view of the cover retaining part 36 is shown, by means of which the covers 37, in particular the underside cover for the conveying device 1, can be fixed to the frame profiles 3a, 3b. The cover retaining part 36 has a further embodiment of the connecting assembly 12. Similarly to the examples shown hitherto, the mounting receptacle 13 includes a connecting device 22 which is configured as a T-head screw.

[0198] The base body has a bottom wall 14 on which the connecting element 18 is arranged. The connecting element 18 is configured similarly to the previously shown embodiments of the connecting assembly 12. For the cover retaining part 36, the reinforcing element 19 is not necessarily required.

[0199] In this variant, the locking device includes a recess in the bottom wall 14. The locking element 21 is arranged to be movable orthogonally to the bottom wall 14 in the recess such that the locking element 21 can be moved out of the recess. In addition, the locking element 21 is rotatably supported about a locking axis. The locking rotation axis is oriented orthogonally to the bottom wall 14. It is hereby specified that when the locking element 21 is positioned within the recess, the locking element 21 terminates flush with the bottom wall 14 or is arranged to be recessed from the bottom wall 14.

[0200] Figure 10b Shown Figure 10a is the connecting assembly 12 in

[0201] In Figure 10a and Figure 10b the mounting receptacle 13 and the base body of the cover retaining part 36 shown in

[0202] Figure 10c are rigidly connected or integrally constructed.

[0203] A further alternative embodiment of the cover retaining part 36 is shown, in which the mounting receptacle 13 and the base body are pivotally, in particular by means of a hinge, hingedly connected to each other. Thereby the cover 37 can be pivotally fastened to the frame profiles 3a, 3b.

[0203] The fastening of the connecting assembly 12 or the cover retaining part 36 to the mounting leg 7 is basically carried out as shown and previously described in Figure 3a and Figure 3b

[0204] For fastening, first, as Figure 3a shown, the covering part holding portion 36 or the connecting assembly 12 is introduced into the connecting position 24, in which the head of the connecting element 18 passes through the first recess 8 in the recess 8 of the mounting leg 7. Next, the connecting assembly 12 is rotated by a rotation angle α into the mounting position 25.

[0205] In the mounting position 25 of the connecting assembly 12, as can be seen in Figure 11 , the locking element 21 can now move out of the recess and engage with the second recess 8 in the recess 8 similarly to the connecting element 18. Here, the head of the locking element 21 is guided through the second recess 8 in the recess 8.

[0206] Subsequently, the locking element 21 can be rotated, in particular, by 90°, such that the hammer-shaped head of the locking element 21 engages with the mounting leg 7 from behind in the edge region of the second recess 8 in the same manner as the head of the connecting element 18. This is shown in Figure 11 .

[0207] Here, the mounting leg 7 is arranged on the covering part 37. The first edge section of the covering part 37 and the second edge section of the covering part 37 respectively form the mounting leg 7. The covering part 37 can be configured, for example, as the bottom covering part of the conveying device 1, which is fastened to the further legs or covering legs of the frame profiles 3a, 3b by the covering part holding portion 36.

[0208] Figure 12a A cross-section of the covering part holding portion 36 is shown, by means of which the covering part 37 is fastened to the frame profiles 3a, 3b. The covering part 37 or the mounting leg 7 of the covering part 37 is fastened to the covering part holding portion 36 by means of the connecting assembly 12. The connecting device 22 of the covering part holding portion 36 is inserted into and cooperates with the fastening groove 27a on the further legs or covering legs of the frame profiles 3a, 3b in order to fasten the covering part holding portion 36 to the frame profiles 3a, 3b.

[0209] In Figure 12b Another cross-section through the covering part holding portion 36 in the plane of the locking element 21 is shown, which is rotatably and movably supported on the base body of the connecting assembly 12.

[0210] In Figure 13a , a section of an alternative embodiment of the conveying device 1 is shown in a perspective view. The conveying device 1 is basically constructed similarly to the conveying device 1 shown in Figure 1 .

[0211] In the illustrated example, the first frame profile 3a and the second frame profile 3b extend parallel to each other at a distance from each other in the conveying direction of the (not entered) piece goods 2.

[0212] Between the first frame profile 3a and the second frame profile 3b, a plurality of conveying elements 5 are arranged, which define a conveying plane FE.

[0213] Here, the conveying element 5 is configured as a conveying roller. Alternatively, it can be provided, for example, that the conveying element 5 is configured as a conveyor belt or that the conveying element 5 is provided, which is configured as a conveyor belt. The conveyor belt can also be guided around the conveying roller, so that the conveying element 5 is formed by the conveyor belt.

[0214] The piece goods 2 are transported on the conveying plane FE or in a conveying area, which is laterally limited by the side guiding profiles 4a, 4b or by the facing inner sides or guiding sides of the side guiding profiles 4a, 4b and downwardly limited by the conveying plane FE.

[0215] In order to laterally define the conveying area, the first side guiding profile 4a and the second side guiding profile 4b also extend parallel to each other at a distance from each other and in the conveying direction of the piece goods 2.

[0216] The first side guiding profile 4a is mounted on the first frame profile 3a and the second side guiding profile 4b is mounted on the second frame profile 3b. The side guiding profiles 4a, 4b are fastened to the corresponding frame profiles 3a, 3b by means of side guiding holders respectively. In the illustrated embodiment, the side guiding profiles 4a, 4b are mounted by a side guiding holder 6' alternative to the above-mentioned side guiding holder, which is fastened to the sides of the frame profiles 3a, 3b. However, in principle, it is also conceivable to use the side guiding holder with the above-mentioned connecting assembly 12.

[0217] In the illustrated example, side guiding profiles 4a, 4b are provided, which are arranged substantially directly adjacent to their respective frame profiles 3a, 3b. Thus, the conveying device 1 is suitable for transporting piece goods 2 packed in so-called polymer bags.

[0218] Furthermore, the side guiding profiles 4a, 4b each have a guiding side and a mounting side. In the illustrated conveying device 1, the side guiding profiles 4a, 4b are arranged such that the guiding sides of the side guiding profiles face each other or face the conveying area. The mounting sides of the first side guiding profile 4a and the second side guiding profile 4b face away from each other or away from the conveying area. In addition, the side guiding profiles 4a, 4b are each connected to the side guiding holder 6 on the mounting side.

[0219] The frame profiles 3a, 3b basically have a C-shaped cross-section, wherein the side cover 9 is used to enclose or cover the open side of the C-shaped cross-section. Thus, an inner cavity of the frame profiles 3a, 3b defined by the frame profiles 3a, 3b and the side cover 9 is provided. In FIG. 13, a first frame profile 3a with a side cover 9 and a second frame profile 3b without a side cover 9 are shown.

[0220] In order to accommodate the holding parts, the frame profiles 3a, 3b respectively have mounting legs 7, and the mounting legs include a plurality of recesses 8 arranged at intervals from each other, as described above.

[0221] In order to detect the piece goods 2 being transported, the conveying device 1 has one or more gratings, in particular reflective gratings. Two gratings are arranged in the shown section of the conveying device 1. Of course, additional gratings and / or additional sensors 10 can be arranged in sections not shown.

[0222] Such a grating includes a sensor 10 and a light reflector corresponding to the sensor 10, which is not shown in FIG. 13. The sensors 10 are respectively fastened to the first frame profile 3a. The light reflector is mounted opposite to the sensor 10 on the second frame profile 3b or on the second side guiding profile 4b.

[0223] In the shown example, the (not shown) sensor 10 of the first grating is fastened by means of a first sensor holding part 11, which has the aforementioned connecting assembly 12. The shown sensor 10 of the second grating is mounted by means of an alternative sensor holding part 11a, which is fastened to the side surfaces of the frame profiles 3a, 3b. Generally, the sensor 10 can be selectively mounted by means of the first sensor holding part 11 or the alternative sensor holding part 11a.

[0224] In Figure 13b the shown variant, the (invisible) sensor 10 can be mounted by means of another alternative sensor holding part 11b, which is fastened to the first side guiding profile 4a. The another alternative sensor holding part 11b has an outer housing 29 and an inner housing 30 for accommodating the sensor 10, as shown in Figure 7 and Figure 8 shown. The inner housing 30 (as previously described for Figure 7 and Figure 8 described) is pivotally supported on the outer housing 29. The inclination of the inner housing 30 or the sensor 10 can be adjusted by means of the adjusting device previously described for Figure 7 and Figure 8 described. Different from the embodiment shown in Figure 8 , the outer housing 29 shown in Figure 13b does not have a connecting element 18 and a locking element 21.

[0225] In addition, the sensor holding part 11b includes an alternative connecting component with fastening means or clamping means, which fastening means or clamping means cooperate with the upper fastening groove 27b or the lower fastening groove 27b' shown in Figure 14 (as shown in this Figure 13b ). The alternative connecting component can be constructed substantially similar to the mounting section 13 of the side guide holding part 6.

[0226] The sensor 10 includes a light source or light emitter for providing an emitted light beam (see the solid arrows in Figure 14 ) and a light receiver for detecting the light beam. In the shown grating, the emitted light beam is guided from the light source to the light reflector, wherein the emitted light beam crosses the conveying area. The light beam reflected on the light reflector (see the dashed arrows in Figure 14 ) is guided from the light reflector to the light receiver, wherein the reflected light beam crosses the conveying area.

[0227] In order to enable the emitted light beam and / or the reflected light beam to pass through, the first side guide profile 4a has a first through hole 38 and the second side guide profile 4b has a second through hole 38, and the first through hole and the second through hole provide a sensor-side perforated plate and a reflector-side perforated plate. It is hereby stipulated that one perforated plate in the perforated plate is assigned to each sensor 10 and / or each reflector.

[0228] In addition, the sensor 10 can be adjusted relative to the sensor-side perforated plate by an adjusting device, so that the angle between the central axis of the through hole 38 and the emitted light beam can be adjusted. It is further stipulated that the sensor 10 is positioned relative to the through hole 38 such that a part of the light beam is blocked from the through hole 38. Herein, the light beam extends staggeredly with respect to the central axis of the through hole 38. The light reflector can be adjusted in the same way and method, so that the angle between the central axis of the second through hole 38 and the reflected light beam can be adjusted.

[0229] In Figure 14 the cross-section of the first side guide profile 4a is shown and the first frame profile 3a of the alternative conveying device 1 is schematically shown, which first frame profile has a first or upper fastening groove 27b and a second or lower fastening groove 27b'. Thus, the first side guide profile 4a has a greater height or a greater distance between the lower edge and the upper edge of the side guide profile 4a compared to the side guide profile shown in cross-section in Figure 5 and Figure 9 . Thereby, the gap or the vertical distance between the side guide profile 4a and the frame profiles 3a, 3b can be closed or reduced. The second side guide profile 4b can be constructed in the same way and is similarly arranged on the second frame profile 3b.

[0230] The side guide profiles 4a, 4b can be arranged such that the lower edges of the respective side guide profiles 4a, 4b extend below the conveying plane FE, as Figure 14 shown. In other words, the conveying plane FE can extend, in particular, slightly above the lower edges of the side guide profiles 4a, 4b, as in Figure 14 shown.

[0231] For fastening the side guide profiles 4a, 4b, the side guide holders 6' are inserted into the upper fastening grooves 27b, as can be seen in FIG. 13. The side guide profiles 4a, 4b have skirts 39 at their lower ends in order to close or cover the gap or vertical distance between the side guide profiles 4a, 4b and the frame profiles 3a, 3b (as can be seen in Figure 1 ), which is shown in Figure 14 shown.

[0232] Through-holes 38 are arranged in the skirts 39 in order to introduce the emitted and / or reflected light beams not far above the conveying plane FE into the conveying area. Here, the through-holes 38 or the perforated plates can be drilled or punched.

[0233] Finally, it should also be mentioned that with the described connecting assembly 12, a firm and lockable connecting device can be realized, by means of which various holders for the components of the conveying device (such as the side guide profiles 4a, 4b, the connecting elements 18, the sensors 10, the reflectors, the coverings 37, in particular the bottom-side covering, etc.) can be fastened to the frame profiles 3a, 3b of the conveying device 1. Thus, such holders can be implemented, for example, as side guide holders 6, sensor holders 11 and covering holders 36.

[0234] Therefore, the connecting device according to the invention is universal and can be used in a simple manner and method and simplifies the installation work on the conveying device 1. In addition, by means of the through-holes 38, the field of use of the conveying device 1 can be expanded.

[0235] Finally, it should also be pointed out that the scope of protection is determined by the claims. However, the claims should be interpreted with reference to the description and the drawings.

[0236] In particular, it is also pointed out that the device shown can in practice also include more or fewer components than shown. The device shown or its components can also be shown partially out of proportion and / or enlarged and / or reduced.
