This application claims priority to and incorporates herein by reference the German patent application DE 10 2022 118 569.9, filed on Jul. 25, 2022.
The invention concerns a handling device for filling one or several product-receiving container/s with products, with at least one feeding unit for a feeding of the products and with at least one handling unit for a handling of the products.
Handling devices of this kind are already known, wherein in the already-known handling devices products go through a plurality of handling stations in order to be fed to a product-receiving container in a desired orientation, or complex and cost-intensive handling units, like for example multi-axis industrial robots or the like, are used to bring the products into a desired orientation. Moreover, with the already-known handling devices an undesired machine stop may occur if, for example, products are in a faulty orientation and therefore a filling of product-receiving containers must be interrupted in order to remove the misaligned product from the production line.
Furthermore, from DE 20 2012 004 631 U1 a packaging machine with at least one handling device is already known, the handling device being configured for filling one or several product-receiving container/s, in particular packagings realized as tubular bags, with products, in particular food products, and comprising at least one feeding unit for a feeding of the products, at least one handling unit for a handling of the products, in particular for taking over the products from the feeding unit, and at least one alignment unit, which is configured to align the products at least with respect to a vertical plane, in order to feed the products to the product-receiving container or to the product-receiving containers in a predetermined orientation.
The objective of the invention is in particular to provide a generic handling device, a generic packaging machine and/or a generic method having improved properties with regard to a reliable and procedurally stable alignment of products, which can be enabled in a manner optimized in terms of cost and installation.
The invention is based on a handling device for a filling of one or several product-receiving container/s, in particular packaging/s, with products, in particular with food products, comprising at least one feeding unit for a feeding of the products, further comprising at least one handling unit, in particular a vacuum gripper unit, for a handling of the products, in particular for taking the products over from the feeding unit, and comprising at least one alignment unit which is configured for an alignment of the products transferred to the alignment unit by the handling unit, at least with respect to a vertical plane, in particular using a weight force of the products, in order to feed the products to the product-receiving container or to the product-receiving containers in a predetermined orientation, in particular for an alignment of the products from a horizontal orientation of the products into a vertical orientation of the products, so as to feed the products to the product-receiving container or to the product-receiving containers in a predetermined orientation.
It is proposed that the alignment unit comprises at least one, in particular movably supported, transfer element and at least one, in particular movably supported, support element, which are configured to alternatingly hold the products in the product-receiving container or in the product-receiving containers in the predetermined orientation. By means of the implementation according to the invention, it is advantageously possible to realize a reliable and procedurally stable alignment of products, such that products can advantageously be fed to product-receiving containers in a predetermined orientation. Advantageously, constructively simple and secure alignment is enabled. Advantageously, alignment is enabled that is optimized in terms of cost and installation. It is preferably possible to ensure, in a manner simple in terms of construction, that the product is in the predetermined orientation so as to counteract undesired machine stops. It is advantageously possible to realize an alignment function in a com-pact construction space. Advantageously, simultaneous alignment of a plurality of products is possible, thus advantageously enabling high output performance. It is advantageously possible to provide an alignment unit for an alignment of the products using a weight force, said alignment unit having a low number of, in particular individually movable, components. Advantageously, a low-maintenance handling device can be realized.
Preferably the handling device is configured for a filling of packagings with products. Preferentially the handling device is configured for a filling of packagings with food products, in particular biscuits, cookies, bars or the like. Especially preferentially the handling device is configured for a filling of trays with food products, in particular biscuits, cookies, bars or the like, wherein the filled trays are preferably fed to a tubular-bag packaging apparatus of a packaging machine comprising the handling device. The product-receiving container/s is/are preferably embodied at least partly or completely as (a) packaging/s, in particular primary packaging/s. Preferentially the product-receiving container/s is/are embodied as (a) receiving tray/s in which a plurality of products, in particular food products, is arrangeable. However, it is also conceivable that the product-receiving container/s is/are realized in a different implementation deemed expedient by someone skilled in the art. “Configured” is in particular to mean specifically prepared, specifically programmed, specifically designed and/or specifically equipped. By an object being configured for a certain function is in particular to be under-stood that the object fulfills and/or carries out said certain function in at least one application state and/or operation state.
In a production line, the handling device, in particular the packaging machine comprising the handling device, is preferably supported downstream of a production machine for producing the products, in particular the food products. The production machine may be, in particular directly, connected to the handling device, in particular to the feeding unit of the handling device, via conveying devices, in particular transport belts or the like. However, it is also conceivable that the production machine and the handling device, in particular the packaging machine comprising the handling device, are arranged at different production locations and are not connected via conveying devices, such that products are delivered to the feeding unit of the handling device in order to be processed by means of the handling device. The feeding unit is preferably embodied as a transport belt unit. It is however also conceivable that the feeding unit presents a different implementation, deemed expedient by someone skilled in the art, like for example an implementation as a chain conveying unit, as a vacuum gripper unit, as an electrodynamic conveying unit, or the like. A transport area of the feeding unit preferably extends at least substantially parallel to a horizontal plane. “Substantially parallel” is in particular to mean an orientation of a direction relative to a reference direction, in particular in a plane, wherein the direction has a deviation from the reference direction that is in particular smaller than 8°, advantageously smaller than 5° and especially advantageously smaller than 2°. The feeding unit preferably comprises a feed transport direction extending at least substantially parallel to a transport-away direction of a transport-away unit of the handling de-vice. However, in particular in an alternative implementation of the handling device, it is also conceivable that the feed transport direction of the feeding unit runs transversely, in particular at least substantially perpendicularly, to the transport-away direction of the transport-away unit. The term “substantially perpendicularly” is in particular meant to define an orientation of a direction relative to a reference direction wherein, in particular viewed in a projection plane, the direction and the reference direction include an angle of 90° and the angle has a maximal deviation that is in particular smaller than 8°, advantageously smaller than 5° and especially advantageously smaller than 2°.
The transport-away unit is preferably configured for transporting the filled product-receiving container/s away and/or further on, in particular for a further transport of the filled product-receiving container/s to the tubular-bag packaging apparatus. The transport-away unit is preferably configured as a stepper-conveyor unit, like for example as a chain conveying unit or the like. It is however also conceivable that the transport-away unit has a different implementation, deemed expedient by someone skilled in the art, like for example an implementation as a conveyor belt unit, as a vacuum gripper unit, as an electrodynamic conveying unit, or the like. The transport-away unit is preferentially configured for a multi-row conveying of product-receiving containers. Preferably the transport-away unit comprises a plurality of transport tracks which are aligned at least substantially parallel to one another and are separated by sidewise guiding elements, like for example guiding plates, sidewalls, or the like. The transport-away unit is preferentially configured for a transport of the product-receiving container/s underneath the handling unit and/or underneath the alignment unit. Preferably, for a filling with products, the product-receiving container/s can be transported by means of the transport-away unit underneath the handling unit and/or underneath the alignment unit.
The handling unit is preferably configured for taking on, in particular receiving, the products from the feeding unit and for transferring the products to the alignment unit. The handling unit is preferentially embodied as a vacuum gripper unit. Preferably the handling unit has a movement axis along which handling elements, in particular vacuum grippers, of the handling unit are movable. The at least one movement axis of the handling unit preferentially extends at least substantially parallel and/or at least substantially perpendicularly to the horizontal plane. Preferably the at least one movement axis of the handling unit extends at least substantially perpendicularly to the transport-away direction of the transport-away unit. The handling unit, in particular the handling elements, may be movable along the at least one movement axis, which extends at least substantially perpendicularly to the transport-away direction and at least substantially parallel to the horizontal plane, and may be additionally movable along at least one further movement axis of the handling unit, which extends at least substantially perpendicularly to the transport-away direction and at least substantially perpendicularly to the horizontal plane. It is also conceivable that the handling unit has a different implementation, deemed expedient by someone skilled in the art, like for example an implementation as a pusher unit configured for transferring the products from the feeding unit, which is for example embodied as a conveyor belt unit extending transversely to the transport-away unit, to the alignment unit. It is also conceivable that the handling unit is embodied as a conveyor belt unit, as a chain conveying unit, as an electrodynamic conveying unit or something like that. In an alternative implementation, the handling unit may also be realized at least partly in a one-part implementation with the feeding unit. It is for example conceivable that the feeding unit is embodied as a conveyor belt unit and the handling unit is realized as a pivotable conveyor belt section of the conveyor belt unit, wherein a transfer of the products to the alignment unit is realizable by a pivoting or tilting of the conveyor belt section, in particular a pivoting or tilting of the conveyor belt section around a pivot axis of the handling unit extending at least substantially parallel to the horizontal plane. By “a unit being realized at least partly in a one-part implementation with a further unit” is in particular to be understood that the unit and the further unit have at least one component they both use in order to fulfill a function. The handling unit may alternatively also have an implementation like the handling unit already known from DE 10 2020 114 084 A1. Particularly preferentially the handling unit is configured for receiving the products from the feeding unit and to transfer them to the alignment unit, by means of which the products are transferred to one or several product-receiving container/s, in particular conveyed into the product-receiving container/product-receiving containers.
The alignment unit is preferably configured to transfer the products from a horizontal orientation of the products into a vertical orientation of the products in order to feed the products to the product-receiving container/s in a predetermined orientation, in particular in the vertical orientation. Preferentially the products are transported by the feeding unit and/or by the handling unit in a vertically aligned state. Preferably a transfer of the products from the feeding unit to the alignment unit is realized by means of the handling unit. The products may be taken on by the alignment unit, already in a transfer from the handling unit to the alignment unit, such that they are—in particular slightly—inclined relative to the horizontal plane, or the products may be taken on by the alignment unit, in a transfer from the handling unit to the alignment unit, in a horizontally aligned state. In the case of a horizontally oriented transfer of the product/s, it is conceivable that the alignment unit has at least one alignment surface which is supported so as to be pivotable around a pivot axis of the alignment unit that extends at least substantially parallel to the horizontal plane, wherein the product/s can be deposited on said alignment surface by the handling unit. For example, following a deposition of the product/s, the pivotably supported alignment surface is pivotable toward the product-receiving container/s, in particular for the purpose of changing an orientation of the product/s from a horizontal orientation into a vertical orientation. It is also conceivable that, with a horizontally orientated transfer of the product/s from the handling unit, the alignment unit has at least one alignment surface which is angled with respect to the horizontal plane. Further implementations of the alignment unit for a transfer of the products into a vertical orientation, deemed expedient by someone skilled in the art, are also conceivable.
It is further proposed that the alignment unit comprises at least the transfer element, which is in particular supported movably, having at least one alignment surface, in particular the aforementioned alignment surface, that is angled relative to a feeding plane of the feeding unit, and comprises at least the support element, which is in particular supported movably, having at least one alignment surface that is angled relative to the feeding plane, wherein, in particular along a direction running transversely to one of the alignment surfaces, the alignment surface of the transfer element and the alignment surface of the support element are spaced apart from each other, in particular for the purpose of delimiting an alignment gap of the alignment unit by means of which the products can be held in an alignment position during a feeding to the product-receiving container/s. Preferentially the transfer element is sup-ported so as to be at least translationally movable, in particular along a movement axis of the transfer element that extends at least substantially perpendicularly to the horizontal plane. Alternatively or additionally, the transfer element is supported so as to be movable in a pivot-able or tiltable manner around a movement axis of the transfer element that extends at least substantially parallel to the horizontal plane. The feeding plane of the feeding unit preferably extends at least substantially parallel to the horizontal plane. Preferentially the feeding plane is equivalent to a plane in which the products are movable, in particular moved, by means of the feeding unit. The feeding plane may be formed, for example, by a transport area of a feeding element of the feeding unit, and/or the feeding plane extends at least substantially parallel to the transport area of the feeding element of the feeding unit. Preferentially the support element is supported so as to be at least translationally movable, in particular along a movement axis of the support element that extends at least substantially parallel to the horizontal plane. Alternatively or additionally, the support element is supported so as to be movable in a pivotable or tiltable manner around a movement axis of the support element that ex-tends at least substantially parallel to the horizontal plane. Preferentially the support element, in particular the alignment surface of the support element, and the transfer element, in particular the alignment surface of the transfer element, are spaced apart from each other at least in an operating state. The alignment surface of the transfer element preferably includes an angle with the feeding plane that is in particular than 180°, preferentially smaller than 90° and particularly preferentially smaller than 60°. The alignment surface of the support element preferably includes an angle with the feeding plane that is in particular smaller than 180°, preferentially smaller than 90° and particularly preferentially smaller than 80°. The alignment surface of the transfer element, which is angled relative to the feeding plane, may be realized by an arc-shaped contour of the alignment surface of the transfer element, with a tangent of the alignment surface including, in each point of the alignment surface of the transfer element, an angle with the feeding plane that differs from 0°, 180° and 360°, or may be realized by a bent-off contour of the alignment surface of the transfer element relative to a further surface, in particular to a further alignment surface, of the transfer element, with the alignment surface including an angle with the feeding plane that differs from 0°, 180° and 360°. This applies analogously to the alignment surface of the support element as well. The implementation according to the invention advantageously allows constructively simple and secure alignment. Preferably it is possible to ensure in a constructively simple manner that the product is in the predetermined orientation, thus counteracting undesired machine stops. Advantageously, reliable and procedurally stable alignment of products can be realized, thus advantageously enabling a feeding of products to product-receiving containers in a predetermined orientation.
Moreover, it is proposed that the alignment unit comprises at least the, in particular movably supported, transfer element, in particular the aforementioned transfer element, having at least two alignment surfaces which are angled relative to each other and which the products can be adjoined to during a feeding to the product receiving container/s. Preferably, during a feeding to the product receiving containers, the products can be transferred into the product-receiving container/s and/or aligned in a gliding fashion. Preferentially the transfer element has the alignment surface and a further alignment surface which is arranged directly next to the alignment surface. The further alignment surface of the transfer element preferably includes an angle with the feeding plane which is in particular smaller than 180°, preferentially smaller than 90° and particularly preferentially smaller than 70°. The alignment surface and the further alignment surface of the transfer element may be formed by an, in particular single, arc-shaped contour of an outer surface of the transfer element or by a contour of two portions of the outer surface of the transfer element which are bent off relative to each other. The implementation according to the invention advantageously enables step-wise alignment of the products. Advantageously, alignment and/or transfer of the products are/is enabled in a manner that is gentle on the products. Advantageously, constructively simple and secure alignment is enabled. Preferably it is possible to ensure in a constructively simple manner that the product is in the predetermined orientation, thus counteracting undesired machine stops. Advantageously, reliable and procedurally stable alignment of products can be realized, thus advantageously enabling a feeding of products to product-receiving containers in a predetermined orientation.
Preferably the transfer element is in at least one support state configured for holding the products already located in the product-receiving container/s and in addition the newly aligned product in the predetermined orientation, wherein the products already located in the product-receiving container/s are supported on a support surface of the transfer element whereas the newly aligned product is supported on a further support surface of the transfer element which faces away from the support surface of the transfer element. Preferentially the support surface and the further support surface of the transfer element in each case include an angle with the feeding plane that is in particular smaller than 180°, that is preferably smaller than 120° and is particularly preferably 90°. Preferentially the support element is in the sup-port state configured to support the newly aligned product by a support surface of the support element that faces towards the transfer element. Preferably the support surface of the support element includes an angle with the feeding plane that is in particular smaller than 180°, that is preferentially smaller than 120° and is particularly preferentially 90°. Preferably the transfer element is movable out of the support state as a result of a relative movement, in particular a lifting movement, relative to the support element, in particular in such a way that the transfer element is free of a contact with the products, and is preferably no longer in direct contact with the products. Preferentially the support element, in particular together with the newly aligned product adjoining the support surface of the support element, is movable relative to the transfer element, in particular translationally movable, preferably in such a way that the support element displaces the newly aligned product towards the products which are already located in the product receiving container/s, until the newly aligned product adjoins the products which are already located in the product receiving container/s. Preferentially, the movement of the support element for a line-up of the products in the product-receiving container/s brings about a translational movement of the product-receiving container/s into a loading position, in particular such that a further product can be fed to the product-receiving container/s at a free position in the product-receiving container/s. The translational movement of the product-receiving container/s into the loading position may be brought about by the support element pushing the product-receiving container/s and/or by the transport-away unit moving the product-receiving container/s. Preferentially, in particular following a movement of the product-receiving container/s into the loading position, the transfer element is movable into the support state,
in which the support surface of the transfer element that faces away from the support element is adjacent to the product that was arranged in the product-receiving container/s most recently. The support element is preferably movable into an alignment state, in which the support element is configured for an alignment of products fed in by the handling unit. In at least one operating state, preferably the support element supports the products already located in the product-receiving container/s, and in at least one operating state, preferentially the transfer element supports the products already located in the product-receiving container/s. By means of the implementation according to the invention, constructively simple and secure alignment is enabled. It is advantageously possible to counteract an undesired tumble-down of the products. Advantageously, reliable and procedurally stable alignment of products can be realized, advantageously allowing a feeding of products to product-receiving containers in a pre-determined orientation, with the products remaining in the predetermined orientation after the feeding.
Beyond this it is proposed that the alignment unit comprises at least the, in particular movably supported, transfer element, in particular the aforementioned transfer element, and at least the, in particular movably supported, support element, in particular the aforementioned support element, wherein, in particular viewed along a longitudinal extension axis of the alignment unit, the transfer element and the support element are arranged offset from each other. Preferably the alignment unit comprises a plurality of transfer elements, which are preferentially realized identically to one another. Preferentially the transfer elements are connected to one another via at least one connection element of the alignment unit; they are in particular realized in a one-part implementation with one another. “In a one-part implementation” is in particular to mean at least connected by substance-to-substance bond, for example by a welding process, a gluing process, an injection-molding process and/or a further process that is deemed expedient by someone skilled in the art, and/or advantageously formed in one piece, like for example by a production from a cast and/or by a production in a one-component or multi-component injection molding process, and advantageously from a single blank. The transfer elements are in particular arranged in an even distribution along the longitudinal ex-tension axis of the alignment unit. Preferentially, viewed along the longitudinal extension axis of the alignment unit, two transfer elements are arranged spaced apart from each other, in particular in such a way that there is an interstice between the two transfer elements. In particular, the plurality of transfer elements forms a rake-like structure. Preferentially the alignment unit comprises a plurality of support elements, which are preferably realized identically to one another.

The alignment unit 20 is preferably configured to transfer the products 14 from a horizontal orientation of the products 14 into a vertical orientation of the products 14 in order to feed the products 14 to the product receiving container 12 and/or to the product-receiving containers 12 in a predetermined orientation, in particular in the vertical orientation. Preferentially the products 14 are transported by the feeding unit 16 and/or by the handling unit 18 in a vertical orientation. Preferably, a transfer of the products 14 from the feeding unit 16 to the alignment unit 20 is brought about by the handling unit 18. The products 14 may, already in a transfer from the handling unit 18 to the alignment unit 20, be taken over by the alignment unit 20 such that they are, in particular slightly, inclined with respect to the horizontal plane, or the products 14 may be taken over by the alignment unit 20, in a transfer from the handling unit 18 to the alignment unit 20, such that they are oriented horizontally.
The alignment unit 20 comprises at least one, in particular movably supported, transfer element 24, which has at least one alignment surface 28, 30 that is angled relative to a feeding plane 26 of the feeding unit 16, and comprises at least one, in particular movably supported, support element 32, which has at least one alignment surface 34 that is angled relative to the feeding plane 26, wherein the alignment surface 28, 30 of the transfer element 24 and the alignment surface 34 of the support element 32 are spaced apart from each other, in particular along a direction extending transversely to one of the alignment surfaces 28, 30, 34, in particular in order to delimit an alignment gap of the alignment unit 20 by which the products 14 can be held in an alignment position during a feeding to the product-receiving container/s 12 (see also
The alignment unit 20 preferentially comprises at least the, in particular movably supported, transfer element 24 having at least two alignment surfaces 28, 30, which are angled relative to each other and which the products 14 can be adjoined to during a feeding to the product-receiving container/s 12 (see
The alignment unit 20 further comprises at least the, in particular movably supported, transfer element 24 having at least one alignment surface 28, 30 which is angled relative to the feeding plane 26 and which the products 14 can be adjoined to during a feeding to the product-receiving container/s 12, and having at least one support surface 38 for holding the products 14 in an alignment position, wherein the alignment surface 28, 30 and the support surface 38 are arranged on sides of the transfer element 24 which face away from each other (see
The alignment unit 20 preferably comprises at least the, in particular movably supported, transfer element 24 and at least the, in particular movably supported, support element 32, which are alternatingly configured to hold the products 14 in the product-receiving container/s 12 in the predetermined orientation (see for example
