Description

Technical Field

[0001] The present invention relates to: an apparatus for unpacking optical workpieces according to the foregoing portion of claim 1, particularly a lens blank for spectacle lenses; a method for unpacking optical workpieces (particularly lens blanks for spectacle lenses) according to the foregoing portion of claim 12; and an application of the apparatus for unpacking optical workpieces (particularly lens blanks for spectacle lenses). Background Technology

[0002] In automated production processes, especially in the manufacture and / or processing of spectacle lenses, automated unpacking of optical components (particularly lens blanks) is beneficial for low-cost manufacturing.

[0003] EP 3 819 092 A1 discloses an apparatus and method for unpacking lens blanks from a box-shaped package, wherein the package is cut or sawn open, particularly on the opposite side. This may result in unwanted dust, which can adversely affect the production process. Furthermore, there is a risk that the lens blank or the inner packaging used to hold the lens blank may be damaged due to the prescribed separation of a portion of the package.

[0004] EP 4 173 979 A1 discloses an apparatus and method for unpacking lens blanks, wherein the packaging is cut using a laser. However, this method also generates undesirable contaminants, particularly particulate or gaseous contaminants, which can adversely affect the manufacturing process or require additional cleaning steps.

[0005] DE 10 2013 019 921 A1 discloses a package for eyeglass lenses, and a package in which a perforation is opened along a predetermined break line by applying pressure to the upper end region of the package. This method requires very specialized packaging. Furthermore, the tearing process is often accompanied by the formation of undesirable particles and dust.

[0006] The variety of packaging available on the market is also an issue. Depending on the manufacturer and / or supplier, the workpiece is packaged in different ways. (External) packaging is often designed as a box, particularly a rectangular box, for example, which is closed by an insert tongue on one side (particularly the narrow side) or an insert tongue on the opposite side and / or the narrow side. Alternatively or additionally, the packaging and / or box may also be tearable on one side (particularly the flat side).

[0007] In addition, the workpiece is usually held in place by an inner package (such as an inner support structure, a packaging tray, a blister pack, etc.), and / or the workpiece is provided with an (additional) outer shell, such as a folded sleeve, a pocket for insertion, etc. Summary of the Invention

[0008] The purpose of this invention is to describe an apparatus, method, and application for automatically removing packaging, which is capable—at least to the greatest extent possible—of opening packaging in a contamination-free manner, and / or is generally applicable, particularly in the presence of different outer and / or inner packaging.

[0009] The above-mentioned objectives can be achieved by the device according to claim 1, by the method according to claim 12, or by the use according to claim 20. Advantageous improvements are the subject of the dependent claims.

[0010] This invention relates in principle to the unpacking of optical components, particularly optical lens blanks or spectacle lenses, and especially preferably, to the unpacking of optical components used in the production and / or processing of spectacle lenses. For simplicity, the following text will generally only refer to the components.

[0011] According to one aspect of the invention, the device preferably includes an opening device with an opening element for laterally inserting under or engaging the side flap of the package from below, and / or for flipping open the side of the package or the side flap. In particular, the opening element is wedge-shaped. This allows the package to be opened without cutting or sawing, thereby preventing the generation of unwanted dust. Specifically, packages with insert-type seals can therefore be opened in a simple and defined manner by inserting a tongue-like element.

[0012] According to another aspect of the invention, which can also be implemented independently, the device preferably includes two opening devices, an adjusting device, and / or a measuring device. The opening devices are used to open opposite sides of the package, and the adjusting and / or measuring devices are used to automatically adapt the spacing and / or position of the two opening devices or their opening elements to the package to be opened, and / or to automatically adapt the position or orientation of the opening devices to the side to be opened. This allows for automatic adaptation to the corresponding package or box, compensating for tolerance deviations even for packages of the same actual size, and enabling the automatic opening of different package sizes in a simple manner.

[0013] In another aspect, which can also be implemented independently according to the invention, the device is preferably configured to open the flat side or top side of the package. This makes automatic removal of the workpiece easier.

[0014] According to another aspect of the invention, which can also be implemented independently, the device is preferably configured to simultaneously remove two workpieces and / or simultaneously open two packages. This enables particularly high throughput.

[0015] According to another aspect of the invention, which can also be implemented independently, the device preferably includes a return device for specifically returning the (intact) package and the corresponding workpiece to the transport carrier in the event of an error during opening and / or removing the packaging. This enables and simplifies fault checking, particularly in a manual manner.

[0016] According to another aspect of the invention, which can also be implemented independently, the device is preferably configured for automatically opening packages of different packaging variations or different sizes, and / or the device is configured for automatically removing workpieces packaged in different ways. In particular, the device includes different opening stations or opening devices adapted or configured for opening different packages. This enables the device to be versatile.

[0017] The proposed method for removing packaging from optical workpieces is characterized by the automatic pull-out of the insert seal and / or the folding and unfolding of the cover from the lower engaging side using an opening device. This enables uncontaminated opening and avoids the risk of damage to the contents of the packaging, specifically the workpiece or inner packaging.

[0018] Another aspect of the invention, which can also be implemented independently, is that the position or location of the opening device automatically adapts to the actual position or location of the side or side flap to be opened. This facilitates automatic and precise opening of the package, effectively preventing undesirable damage to the workpiece.

[0019] According to another aspect of the invention, which can also be implemented independently, the packaging of the workpiece is preferably opened on opposite sides, particularly by flipping open the side flaps, and additionally, the packaging of the workpiece is preferably opened on the transverse side, especially by cutting, so that the flat side or top side of the packaging can be flipped open. Tests show that opening the packaging is very efficient and the workpiece can be removed in a simple manner.

[0020] Particularly preferably, the proposed device is used for removing optical workpieces, wherein the outer packaging of workpieces to be opened in different ways is opened by means of the same device, and / or wherein the workpiece is removed from inner packaging of different structures by means of the same device, and / or wherein the outer packaging is opened first, and then the workpiece is removed from the inner packaging by means of the same device. In this way, the automatic removal of workpieces even those packaged in different ways can be achieved in a very efficient manner.

[0021] The aspects and features described above, as well as the aspects and features resulting from the following description, can be implemented, in particular, in a manner independent of each other, or in any desired combination. Attached Figure Description

[0032] In the illustrated example, the package 3 or the outer package 4, or one or more opposing sides or narrow sides 4B of the outer package 4, are preferably closed by means of an insert-type seal 4C or an insert-type tongue 4C.

[0033] When the package 3 or the outer package 4 is not opened, the insert tongue 4C specifically keeps the connected side flap 4D closed.

[0034] In addition to the insert-type sealing element 4C and / or the insert-type tongue element 4C, the side-folding cover 4D can also be kept closed alternatively or additionally by other means, such as by adhesive elements, adhesives, etc.

[0035] When the package 3 or the outer package 4 is closed, the side flap 4D that needs to be opened is specifically formed on the side or narrow side 4B of the package 3 or the outer package 4.

[0036] According to Figure 2A and Figure 2B In variations of the implementation, the package 3 or the outer package 4 is preferably openable on two opposing sides or a narrow side 4B, and / or is provided with an insert-type seal or an openable side flap 4D and / or an insert-type tongue 4C.

[0037] According to Figure 2C In the third embodiment variant, the package 3 or the outer package 4 is preferably openable only on one side or narrow side 4B, or the package 3 or the outer package 4 is provided with an openable side flap 4D or an insertable tongue 4C.

[0038] Alternatively or additionally, according to a variant of the third embodiment, the package 3 or the outer package 4 preferably has a tear-open side or an openable flat side or a covered side or upper side 4E.

[0039] Particularly preferably, the openable or foldable side cover 4D is connected to the side or flat side 4E, which can be opened in particular by tearing, especially via a bend or crease 4F. However, other structural embodiments are also possible.

[0040] exist Figure 2C In the middle, the partially opened state of the side folding cover 4D and the upper cover 4E is indicated by dashed lines.

[0041] Optionally, an unshown sidewall of the package 3 may also be provided behind the flip-open or foldable side cover 4D, so that even if, for example, no sidewall is present... Figure 2C When the inner packaging 5 or inner layer structure 5C is in the middle, the workpiece 2 will not slide out to the left when the packaging 3 is flipped up.

[0042] The openable or tearable side or top 4E does not necessarily involve the entire surface of the package 3 or outer package 4, but may only form a partially openable cover or section of the package 3 or outer package 4. For according to Figures 2A to 2C All variations of the implementation are also preferably applicable to other openable side or side-folding covers 4D.

[0043] Package 3 may optionally also have an inner package 5, which is specifically contained by the outer package 4, and / or, if necessary, the inner package may be formed by the outer package.

[0044] According to Figure 2A In the first embodiment variant, the inner packaging 5 is preferably designed as a packaging tray or blister pack 5A.

[0045] In a first embodiment variant, the inner packaging 5 is preferably configured such that the workpiece 2 is exposed through, in particular, the flat side 2A to be processed (pointing upward in FIG2) or that the workpiece 2 can be removed from the inner packaging 5, which can only be done after the outer packaging 4 has been opened or removed.

[0046] The inner packaging 5 or packaging tray or blister 5A preferably holds the workpiece 2 generally only at the edge or prevents it from being held on the finished side 2B (the underside in this application), and / or makes the finished flat side 2B of the workpiece 2 covered by the inner packaging 5, or kept spaced apart from the inner packaging 5, or protects the finished flat side 2B of the workpiece 2 from external influences or damage or contamination.

[0047] The flat side 2A to be processed is drawn flat. However, usually or preferably, this flat side is constructed to be concave and in particular forms a so-called rezeptfläche (finished side). On the other hand, the finished side 2B is preferably constructed to be convex.

[0048] According to Figure 2B In a second embodiment variant, the inner packaging 5 is preferably formed of or includes a wrapping layer 5B. Specifically, the wrapping layer 5B is formed as a folded sleeve, a folded sheet material (e.g., made of foam material), a soft or cushioning pad or air-cushioned film, a pocket for insertion, etc. The inner packaging 5 or the wrapping layer 5B also serves to protect the workpiece 2, particularly its (optionally processed) flat side 2B, from damage or other influences (e.g., contamination).

[0049] According to Figure 2C In a third embodiment variant, the inner packaging 5, which is provided only optionally, is preferably formed of an inner layer structure 5C that holds the workpiece 2 so that the workpiece can be removed after the packaging 3 or the outer packaging 4 (particularly the lid or the upper side 4E) is opened.

[0050] The inner structure 5C can also optionally be configured to be used according to Figure 2A and / or Figure 2B The packaging 3 replaces the packaging pallet 5A and / or wrapping layer, or the inner structure may partially or at the edge surround or overlap the workpiece 2.

[0051] The illustrated examples show different packaging variations, specifically different packages 3, or different outer packaging / outer packaging 4, and different inner packaging / inner packaging 5.

[0052] Particularly preferably, the device 1, the proposed method, and the proposed uses are constructed or configured to automatically unpack different packages 3, outer packages 4 and / or inner packages 5 in the aforementioned sense, and / or to automatically unpack packages 3, outer packages 4 and / or inner packages 5 of different sizes, thereby making the device 1 and the method universally applicable.

[0054] The conveying device 10 is particularly preferably configured as a circulating conveyor, a conveyor belt, or a belt conveyor.

[0055] The conveying device 10 preferably extends along one side of the equipment 1.

[0056] The workpiece 2 and / or package 3 to be unpacked are preferably fed / supplied onto or into the transport carrier 11 by means of a conveying device 10. The transport carrier 11 is particularly preferably configured as a transport container and / or for receiving two workpieces 2 and / or packages 3 respectively.

[0057] The transport carrier 11 is also preferably used to transport the workpiece 2, which has been unpacked.

[0058] The conveying direction or main extension direction of the conveying device 10 is preferably parallel to one side of the equipment 1, or extends along the X direction and / or extends in the horizontal direction.

[0059] The conveying device 10 can optionally be connected to the equipment 1 via the connector 12.

[0060] Figure 1 A schematic overview of a particularly preferred structure of the device 1 proposed according to the first embodiment is given.

[0061] The device 1 preferably includes a loading device 20, a positioning device 30, a steering device 40, a transfer device 50, a separation device 60, an unpacking device 70, a delivery device 80, a (first) opening station 100, and / or (another or second) opening station 200.

[0062] The device 1 or loading device 20 is preferably configured to receive the package 3 carrying the workpiece 2 from the conveying device 10 or from the transport carrier 11, and / or to transport or transfer the package 3 carrying the workpiece 2 to the positioning device 30, the steering device 40 and / or the transfer position P1.

[0063] Figure 3A portion of the device 1 in the area of ​​the loading device 20, positioning device 30, and steering device 40 is schematically shown.

[0064] The loading device 20 preferably has a loading manipulator 21, which in particular has an adsorption member 22 or other holding member to be able to grasp or pick up the package 3 with the workpiece 2.

[0065] The package 3 is preferably able to be lifted by means of a loading robot 21, and in particular, can optionally be rotated about an axis, especially a vertical one.

[0066] In the illustrated example, the holding or adsorption member 22 is particularly movable in the vertical or Z direction to lift and place the package 3, can move in the horizontal or Y direction (particularly transverse to the conveying direction X), and / or optionally can rotate about the vertical axis (Z direction).

[0067] Specifically, the loading robot 21 or the adsorption component 22 can move or be displaced linearly or along the Y direction via the slider guide 23, and / or can move or be displaced linearly or along the Z direction via the slider guide 24.

[0068] like Figure 3 As shown, the device 1, loading device 20, or loading robot 21 preferably has a detection device 25 (particularly a camera) for detecting or reading the identification 3A on the package 3. Specifically, optical detection is performed. The identification 3A is, for example, a barcode. However, other identification methods may be used, and alternatively or additionally, an RFID chip may be used for identification; the information from the RFID chip is detected or read, for example, by the detection device 25.

[0069] Data and information provided by an external system (e.g., a lens management system (LMS)) via an information carrier (not shown) on or within the transport carrier 11, and / or available based on input detection, specifically indicate the construction form and / or packaging method of the corresponding workpiece 2, i.e., in particular, which packaging variant or what packaging size, outer package 4, and / or inner package 5 are present. Where necessary, the aforementioned data and information also indicate, for example, the orientation of the workpiece 2 within the package 3 and / or the package 3 during the transport process (e.g., on or within the transport carrier 11). This facilitates automated and safe unpacking, wherein, in particular, the proposed device 1 and the proposed method enable unpacking and removal from different packaging variants or packages 3.

[0070] Optionally, device 1 may check, or optionally as a method step, whether there is a workpiece 2 or more workpieces 2 (i.e., correct workpieces 2) in transport carrier 11 with correct identification 3A bearing information carrier conforming to the corresponding transport carrier 11 and / or data conforming to the system or LMS. This can identify and, for example, sort out incorrect workpieces 2.

[0071] Optionally, the device 1 is configured to detect the corresponding packaging variant and orientation of the package 3 and thereby achieve automatic unpacking, even without supplementary or external information.

[0072] In this application, the placement and / or transfer of package 3 (especially placement and / or transfer to positioning device 30 and / or steering device 40 and / or opening station 100 or 200) is preferably carried out at transfer position P1.

[0073] Figure 3 The image shows package 3 still in transport carrier 11 before being removed, and package 3 in transfer position P1.

[0074] In the exemplary description, device 1 or loading device 20 preferably has a carrier 26 for placing and / or transferring package 3 and Figure 3 Only marked in the middle, but Figure 8 The position after displacement can be observed more clearly in the middle.

[0075] The positioning device 30 is used to define the alignment of the package 3 and is preferably configured to align the package 3 at a corner, i.e., by the two sides and / or narrow side 4B forming the angle, here in the X and Y directions or on the horizontal plane (especially on the carrier 26).

[0076] Preferably, the positioning device 30 has a first positioning element 31 and optionally a second positioning element 32. The first and second positioning elements are specifically configured to be corner-shaped and can be engaged with the diagonally opposite vertical edges or corners of the package 3 in order to align the package 3 in a desired manner, particularly in the transfer position P1 or on the carrier 26.

[0077] In the exemplary description, the two positioning elements 31, 32 can be moved or fed. In particular, the two positioning elements 31, 32 can be moved or fed in the XY plane or horizontal plane, and / or the two positioning elements 31, 32 can be moved along the diagonal of the package 3, 4 (bottom side 4A) to achieve the desired alignment.

[0078] Specifically, the first positioning element 31 is movable to a desired position for aligning the package 3, and then the package 3 is pressed against the first positioning element 31 by the feeding of the second positioning element 32, so that the package 3 and the first positioning element 31 are aligned in the desired manner. If necessary, the second positioning element 32 can also be guided to accommodate a non-square bottom surface by additional lateral displacement. However, other structural solutions are also possible.

[0079] Specifically, the steering device 40 enables the package 3 to be steered or rotated about a horizontal axis. The steering device 40 preferably has a steering manipulator 41, which is designed as a gripper with gripping arms 42 that engage laterally with the package 3 and are particularly preferably capable of feeding in opposite directions in a preferred symmetrical manner.

[0080] In order for the steering device 40 to clamp the package 3 on opposite sides or two narrow sides 4B by its steering manipulator 41, the positioning elements 31 and 32 of the positioning device 30 preferably move apart again after aligning and / or positioning the package 3 before performing the preferred steering.

[0081] The steering manipulator 41 is preferably capable of vertical movement or lifting (see...). Figure 8 And / or be able to pivot about an axis, especially a horizontal one (preferably extending in the Y direction), so that the package 3 can be lifted, turned and repositioned when needed. However, other structural solutions are also feasible.

[0082] The device 1 and / or loading device 20 preferably have a transfer manipulator 27 to transfer the package 3 (especially in positioning or alignment and / or turning or from transfer position P1 or from carrier 26) to a downstream or other device (preferably opening station 100).

[0083] In the illustrated example, the transfer robot 27 is provided with a holding member, specifically an adsorption member 28, and the transfer robot can pick up or lift the package 3 from the transfer position P1 and / or from the carrier 26, and preferably can pivot about a particularly horizontal axis or about an axis extending in the Y direction, so as to transfer the package 3 via a preferably vertically aligned main plane or bottom surface 4A to the opening station 100 or the opening robot 101 of the opening station 100 or to other means of transferring it to the device 1. However, other structural solutions are also possible.

[0084] In the illustrated example, the transfer manipulator 27 is preferably attached to the slider guide 23 in a pivotable manner, meaning that the transfer manipulator 27 can move or be displaced, particularly together with the loading manipulator 21. However, other structural solutions are also possible.

[0085] The adsorption component 28 of the transfer manipulator 27 is preferably movable or fed in a linear manner. However, other structural solutions are also possible.

[0086] Figure 1 The diagram schematically shows the state in which package 3 is transferred from transfer robot 27 to opening station 100, and in particular the state of opening robot 101 transferred to opening station 100, which receives package 3 from loading device 20 or transfer robot 27 at transfer position P2 and holds package 3 in particular by means of adsorption member 101A.

[0087] Packages 3, 4, or their flat / bottom side 4A are preferably configured to be vertical during transfer to the opening station 100 and / or during opening, and / or the side that needs to be opened for the removal of workpiece 2 is preferably pointing downwards.

[0088] The opening manipulator 101 can move together with the held package 3 in a preferably linear manner (especially by means of an adjusting cylinder or linear drive), particularly along the guide or track 102 and or in the horizontal direction or in the Y direction or in the direction transverse to the conveyor 10.

[0089] The opening station 100 preferably includes a (first) opening device 110 and optionally includes a (second) opening device 120.

[0090] exist Figure 1 The opening devices 110 and 120 are only schematically shown. According to... Figure 4A The 3D model shows a more realistic presentation. Figure 4A The key components of the opening station 100 are shown.

[0091] The (first) opening device 110 is preferably configured to open the package 3 or the outer package 4, particularly by opening the narrow side 4B, pulling out the insert tongue 4C and / or flipping open the side flap 4D. For this purpose, the (first) opening device 110 preferably includes a (first) opening element 111, which is specifically configured as wedge-shaped, strip-shaped or tongue-shaped.

[0092] Preferably, opening or unfolding is achieved by inserting the side of the opening element 111 (particularly substantially within the plane of the side to be opened or the side flap 4D) under the side to be opened or the side flap 4D of the package 3 or the outer package 4, and particularly by means of an inclined plane or wedge-shaped surface 111A or by subsequent pivoting. In the illustrated example, this is particularly achieved by the package 3 and the opening device 110 or the opening element 111 of the opening device 110 moving relative to each other by an opening movement B, which, in the case of the opening station 100, is preferably achieved by the opening robot 101 moving past each other along the guide / track 102.

[0093] The (first or lower) opening device 110 preferably includes an opening retainer 112 for keeping the side or side fold cover 4D that has been opened by the opening element 111 open and / or for continuing to fold outward.

[0094] The second or upper opening device 120 is preferably constructed at least substantially correspondingly, in particular constructed to have a second opening element 121 and optionally also an opening retainer 122.

[0095] The device 1 and / or the opening station 100 are preferably configured to open the package 3 or the outer package 4 on opposite sides or two narrow sides 4B, specifically by means of two opening devices 110, 120.

[0096] The package 3 can be moved from the transfer position P2 by means of the opening movement B or by means of the opening robot 101. Figure 1 The open position or transfer position P3 is schematically indicated and / or achieved by moving the package 3 along one or more opening elements 111, 121 or between opening elements 111 and 121.

[0097] The opening manipulator 101 is optionally configured such that it clamps and / or supports the package 3 (by means of section 101B) on the rearward and vertical side or narrow side 4B, so as to prevent the package 3 or the outer package 4 from rotating and / or displacing during opening, since the laterally inserted opening elements 111 and 121 may exert considerable force on the package 3 or the outer package 4.

[0098] Equipment 1 and / or opening station 100 preferably include regulating device 103 ( Figure 4A , Figure 5 ), which is used to open the device 120 or to open the devices 110 and 120 to each other or to open the elements 111 and 121 to each other ( ), Figure 4BAdjustment can be made by means of the adjustment mechanism 103. For example, the adjustment mechanism 103 is designed to adjust a drive or cylinder that can adjust the opening device (here, the second opening device 120), particularly along the linear adjustment direction R and / or relative to the other opening device 110. Alternatively, the other or first opening device 100 can be adjusted by the adjustment mechanism 103 or independently by its own adjustment mechanism (not shown).

[0099] The adjustment direction R preferably extends vertically and / or laterally or perpendicularly to the plane of the side / side flap 4D to be opened and / or laterally or perpendicularly to the opening motion B performed by the opening robot 101 to open the package 3, and / or the adjustment direction R extends within the main plane of the package 3 to be opened.

[0100] In order to automatically adapt to the position of the adjustable opening device 120 (vertical in this case) or between the two opening devices 110, 120 or the opening elements 111, 121 Figure 4B The distance A shown in the diagram, or to enable automatic feeding of the opening device 120 or the opening element 121, the device 1 or the opening station 100 preferably includes a measuring device 104. In particular, the measuring device 104 detects the actual size or side length of the package 3 or the outer package 4, and / or detects the actual position of the side or side flap 4D to be opened. Therefore, the position of the corresponding opening device (here, the second opening device 120) or the position of the second opening element 121 can be correspondingly adapted to the position of the side flap 4D (here, the height of the side flap 4D) so that the opening element 121 can be correctly inserted under the side flap 4D.

[0101] In principle, the two opening devices 110 and 120 may also be equipped with corresponding automatic adjustment devices to adapt to the corresponding positions of the side flaps 4D to be opened. Since in this illustrated example, at least one (in this case, the lower part) of the side or side flap 4D to be opened is positioned in a defined manner, double adjustment is not required (as is preferably specified in the second embodiment), and single-sided adjustment as specified in the illustrated example according to the first embodiment is sufficient to adapt to the actual packaging size.

[0102] Therefore, through the provided adjustment device, the distance A between the two opening devices 110, 120 or between the opening elements 111, 121 is also adapted to the internal distance I of the package 3 or the side flap 4D to be opened, wherein Figure 4B The distance A between the two open elements 111 and 121 and the internal distance I are shown only schematically.

[0103] Optionally, the opening devices 110, 120 or their opening elements 111, 121 are offset by an offset amount V in the direction of the opening movement B or in the insertion direction, such that the opening elements 111, 121 are initially inserted into the package 3 or the outer package 4 sequentially rather than simultaneously, so that the forces acting on the package 3 do not occur simultaneously, but rather occur in a time-staggered manner.

[0104] Figure 4C The opening element 111 in the preferred embodiment is shown in perspective. It can be seen that the opening element 111 particularly has or forms an inclined plane or wedge-shaped surface 111A. Particularly preferably, the angle of the inclined plane and / or wedge-shaped surface 111A is between 10° and 20° at least in the region of the free end of the opening element 111, and / or the opening element 111 is preferably provided with a rounded free end.

[0105] The opening element 111 preferably has a flat bottom side 111B, which points to the workpiece 2 located in the package 3 during insertion and preferably extends parallel to the movement B, i.e., in the direction of lateral insertion.

[0106] In the top view of the bottom side 111B, the opening element 111 is preferably rounded at its front end, and in particular, the opening element 111 is semi-circular at its front end.

[0107] The plane or wedge-shaped surface 111A of the opening element 111, which extends inclined to the bottom side 111B, is preferably transverse to the insertion direction or rounded at the longitudinal edge.

[0108] The second opening element 121 is preferably constructed to be the same as the first opening element 111, but the second opening element 121 may also be designed in a different manner.

[0109] The inclined planes, slopes, or wedge-shaped surfaces 111A and 121A of the opening elements 111 and 121 are preferably directed away from the package 3 to be opened, so that the corresponding side or side flap 4D can be opened as desired by the opening movement B.

[0110] After opening package 3 or outer package 4, remove inner package 5 or workpiece 2. Specifically, this process occurs when... Figure 1 The transfer location is P3, indicated by the dashed line.

[0111] Figure 5 The transfer device 50 is shown schematically and three-dimensionally in detail when picking up or removing the inner package 5 or workpiece 2 from the package 3 or outer package 4 at position P3.

[0112] The transfer device 50 preferably has a transfer manipulator 51, which is specifically provided with grippers or holding arms 52 that can be fed by a motor so as to pick up, hold or clamp the workpiece 2, which preferably still has its internal packaging 5. Particularly preferably, the transfer manipulator 51 picks up, holds or clamps the workpiece 2 from the side and / or on the outer periphery.

[0113] In particular, the transfer robot 51 is configured in a fork or pincer shape to stably pick up and hold the workpiece 2.

[0114] The device 1 or transfer device 50 particularly preferably has at least one detection device (here two or more detection devices 53 and 54) to detect whether the workpiece 2 has been (correctly) picked up by the transfer robot 51, whether the workpiece 2 is provided with an internal package 5 and / or what kind of internal package 5 the workpiece 2 is provided with.

[0115] Preferably, the two detection devices 53 and 54 operate in different ways; for example, the detection device 53 operates in a tactile manner while the detection device 54 operates in an optical manner.

[0116] For example, the first detection device 53 or its sensor 53A is configured as a miniature tactile sensing device to identify whether the workpiece 2 and / or the packaging tray or blister pack 5A serving as the inner packaging 5 has been identified and / or picked up. In particular, the sensor 53A can detect the orientation of the blister pack 5A because the blister pack 5A is configured to be asymmetrical relative to the workpiece plane, which can cause different, detectable deflections of the sensing arm of the sensor 53A.

[0117] The device 1 or detection device 53 preferably (additionally) includes a workpiece sensor 53B, which is particularly capable of detecting the presence and / or curvature of the workpiece 2 and / or the inner packaging 5 or the wrapping layer 5B, and thereby can monitor the orientation of the workpiece 2. In particular, the workpiece sensor 53B includes (preferably arranged adjacent to each other or in a straight line) three tactile sensing devices that are capable (particularly generally centered) abutting against the side or flat side of the workpiece to detect the presence and / or curvature of the workpiece 2 and / or the inner packaging 5 or the wrapping layer 5B, and thereby detect the orientation of the workpiece 2.

[0118] For example, the second detection device 54 is designed as an optical sensor to detect the wrapping layer 5B as the inner packaging 5, and / or to detect what material the inner packaging 5 is made of and / or what color or markings the inner packaging 5 has, and / or to detect whether the inner packaging 5 is transparent, and / or to detect the presence of the workpiece 2.

[0119] Preferably, the device 1 or the second detection device 54 has a camera or multiple cameras (here, two cameras 54A and 54B) so as to enable inspection of the workpiece 2 or its internal packaging 5, particularly from the opposite side or flat side.

[0120] The device 1 and / or the transfer device 50 may optionally have a pusher 55 so as to push the workpiece 2 out of the package 3 or into the transfer robot 51 when necessary. In particular, the pusher 55 pushes the workpiece 2 out of the package 3 from above or from the side opposite to the transfer robot 51 or the take-out side.

[0121] The transfer robot 51 is movable, and preferably, the transfer robot 51 is pivotable about a horizontal axis and / or a vertical axis to transfer the removed workpiece 2 to a downstream device, which is preferably used to remove the inner package 5. In particular, depending on the type of inner package 5, the removed workpiece 2 is selectively transferred to a separation device 60 or an unpacking device 70, and in particular, the removed / taken workpiece 2 is also transferred in a desired direction, especially with the finished side 2B on top.

[0122] Empty package 3 or outer package 4 can be transported away or discharged.

[0123] Equipment 1 or opening station 100 preferably includes a packaging robot 105, the packaging robot 105 being particularly... Figure 1 Empty package 3 or outer package 4 is received at the transfer position P4 (in particular from the opening robot 101) so that the empty package 3 or outer package 4 can be discharged to the disposal device (here, chute 106 or similar device).

[0124] In the illustrated example, the packaging robot 105, which is capable of moving, particularly linearly, and equipped with an adsorption component, can interact with empty packages 3 and 4, particularly horizontally and / or toward them. Figure 1 The conveyor position P5, which is schematically marked in the diagram, is moved to discharge packages 3 and 4 there, for example, by causing packages 3 and 4 to fall. However, other structural solutions may also be used.

[0125] exist Figure 6 The separation device 60 is schematically shown. The separation device 60 preferably has a particularly platform-shaped receiving area 61, which has a preferably integral retainer or adsorption member 62 for holding the workpiece 2, which is transferred or placed thereon by the transfer device 50 or transfer robot 51 (transfer position P6). During transfer, the workpiece 2 retains its internal packaging 5, which, if present, is constructed as a packaging tray or blister pack 5A according to a variant of the first embodiment.

[0126] The separation device 60 preferably includes a robotic arm 63, which in particular has a gripper or suction member 64 for removing and, in particular, transporting the inner packaging 5, which in particular is a packaging tray or blister pack 5A, such as in Figure 6 It is shown schematically in the diagram.

[0127] In the illustrated example, device 1 or separation device 60 preferably has a conveying member 65 for conveying empty inner packaging 5 or packaging pallets or empty blister packs 5A outward.

[0128] like Figure 1 As shown, the empty inner package 5 is preferably transferred by the separation robot 63 to the conveyor 65, such as a conveyor belt.

[0129] The workpiece 2, after being completely unpackaged, can ultimately be transferred again to the conveyor 10 or the (empty) transport carrier 11 by means of the delivery device 80, or specifically transferred back to the original transport carrier 11. For this purpose, the delivery device 80 preferably has a delivery robot 81, and particularly preferably, the delivery robot 81 has a gripper 82, which is preferably movable along the guide 83 and / or in the vertical direction, as in... Figure 1 It is shown schematically in the diagram.

[0130] exist Figure 7A The diagram schematically shows the unpacking device 70 in operation, and the unpacking device 70 is configured to remove the inner package 5 (particularly the wrapping layer 5B) from the workpiece 2.

[0131] The unpacking device 70 preferably has a rolling element 71, which is particularly in the form of a rotatable disc or a rotatable plate, so that the workpiece 2 can roll on the circumferential edge of the rolling element 71 and detach the wrapping layer 5B from the workpiece 2 or detach the workpiece 2 from the wrapping layer 5B. For example, the rolling element 71 may also be formed by an inclined plane and / or an inclined or V-shaped groove, etc.

[0132] Particularly preferably, the rolling element 71 is rotatable and has an edge 72 on which the workpiece 2 can roll circumferentially. In particular, the rolling element 71 supports the workpiece 2, preferably almost upright, preferably on the flat side 2A of the workpiece to be processed.

[0133] After receiving or accepting the workpiece 2, the rolling element 71 tilts upward or flips, specifically, such that the rotation axis D of the rolling element 71 is tilted more than 5° and / or less than 45° or 35° relative to the horizontal direction and rotates, particularly preferably, such that the rotation axis D of the rolling element 71 is tilted between about 10° and 30° relative to the horizontal direction and rotates.

[0134] The unpacking device 70 preferably has an air supply mechanism and / or an adsorption mechanism 75 to assist in the detachment of the packaging layer 5B by airflow and / or to be able to adsorb the detached packaging layer 5B.

[0135] Figure 7B The unpacking device 70 is shown in a schematic rear view during the delivery of workpiece 2 detached from the wrapping layer 5B.

[0136] Preferably, the unpacking device 70 has a transfer area 76 for placing and / or transferring the workpiece 2 (transfer position P8) after the packaging has been completely removed.

[0137] From transfer area 76 or its associated location P8, the unpackaged workpiece 2 can preferably be transferred again by means of delivery device 80 or clamp 82 to conveying device 10 or transport carrier 11, such as... Figure 1 As shown in the image.

[0138] Alternatively or additionally to the opening station 100 and / or to the separating device 60 or the unpacking device 70, the proposed device 1 preferably includes a modified opening station or a second opening station 200, which is specifically configured to open the package 3 or other packages 3 according to a variant of the third embodiment.

[0139] Figure 8 The open station 200 is shown in a three-dimensional and schematic partial view.

[0140] The device 1 or opening station 200 preferably includes (additional, additional, or third) opening device 130 and preferably includes feeding device 201.

[0141] Preferably, the feeding device 201 is used to transfer the package 3 from the transfer position P1, that is, the package 3 which is preferably aligned by means of the positioning device 30 and / or turned by the turning device 40 (as needed), to the opening device 130 or the opening device, and / or to insert the opening element 131 of the opening device 130 preferably from the side into the package 3 or under the side to be opened or the narrow side 4B or the side flap 4D.

[0142] The device 1 or feeding device 201 preferably includes a retainer 202, which is particularly designed in the form of a slider, and the device or feeding device particularly includes a guide rail 203 for displaceable guiding of the retainer 202.

[0143] Specifically, the retainer 202 is platform-shaped and / or provided with only Figure 1The holding device, indicated by the dashed line, such as the adsorption member 202A, is used to hold the package 3 placed on the holder 202, such as... Figure 8 As shown.

[0144] In particular, such as Figure 8 As shown, it is the retainer 202, not the carrier 26, that is capable of moving to the transfer position P1. Preferably, in this case, the carrier 26 can be removed from position P1, specifically pushed away. Alternatively, the carrier 26 can also be guided in a displaceable manner via the guide track 203. However, other structural solutions are also possible.

[0145] Preferably, the opening device 130 is configured such that the side or narrow side 4B or side flap 4D of the package 3 or outer package 4 to be opened can be grasped and / or held or held in a clamping and / or gripping manner. For this purpose, in addition to the opening element 131 that engages with the side and / or side flap 4D from below, the opening device 130 preferably includes a clamping element 132, which preferably forms a grasping device, a clamping device, and / or a clamping forceps together with the opening element 131. For example, the clamping element 132 can be moved or tensioned toward the opening element 131 by means of a clamping drive 138, or the opening element 131 can be moved or tensioned toward the clamping element 132 by means of the clamping drive 138, to induce the desired clamping of the received side and / or side flap 4D. However, other structural solutions also exist in this application.

[0146] The feeding device 201 is preferably configured such that the package 3—particularly by means of the correspondingly driven retainer 202—is movable to the opening device 130, entering the open position P9 (e.g., Figure 1 As shown), and / or the package 3 may be movable relative to the opening device 130 or the opening element 131, so that the opening element 131 can be moved, in particular, laterally or inserted under the side or side flap 4D to be opened and / or the side / side flap 4D to be opened can be moved or inserted into the clamping device or clamping clamp.

[0147] The opening device 130 preferably includes a (first) pivot drive 133 having a (first) pivot axis S1 for opening the side / side flap 4D that engages or receives from below, and / or the latching device optionally includes a (second) pivot drive 134 having a (second) pivot axis S2 for opening / tearing the side / flat side of the package 3. Specifically, the first pivot drive 133 pivotally holds the opening element 131 and the clamping element 132 or the clamping device formed therefrom in a pivotal manner, and is itself preferably pivotally held by the second pivot drive 134. However, other structural solutions are also possible.

[0148] The device 1 or opening device 130 preferably includes—in particular, in addition to the retainer 202 or the adsorption member 202A—a retaining device 135, which is used to retain or hold the package 3 or the outer package 4, particularly in a lateral manner, during opening or in position P9.

[0149] In the illustrated example, in particular, the retaining device 135 includes two driving elements or pivoting devices 136 and 137, which include retaining elements 136A and 137A and / or adsorption members 136B and 137B that are particularly movable or pivotable toward the package 3 on opposite sides.

[0150] exist Figure 8 In this case, the pivot drive 136 and its holding element 136A are preferably lifted, thereby allowing the holder 202 with the package 3 to move into the opening device 130 or position P9.

[0151] Figure 9A The opening station 200 or opening device 130 is shown schematically, in which the still-closed package 3 is in the open position P9. In particular, the opening element 131 has been inserted under the side to be opened, the narrow side 4B, or the side flap 4D.

[0152] The pivot drive 136 has been lowered. The retaining elements 136A, 137A or the adsorption members 136B, 137B have not yet engaged or pressed onto the package 3. The above operation will then be performed.

[0153] Subsequently, the side or side cover 4D is opened by pivoting about the first pivot axis S1 via elements 131, 132 or the clamping device / clamp (particularly when clamping the side / side cover 4D to be opened). The first pivot axis S1 preferably extends at least substantially coaxially with the desired folding axis of the bend or crease 4F or the side cover 4D to be opened.

[0154] After the side fold cover 4D is opened, or regardless of whether it is opened, it is preferably pivoted into place around the second pivot axis S2. Figure 9B In the indicated position, the second pivot axis S2 preferably extends at least substantially coaxial with the rear edge or longitudinal edge 4H of the packages 3, 4, or at least substantially coaxial with another desired folding axis of the side to be opened. During this pivoting, the side, flat side, or upper side 4E connected to the side flap 4D is opened, flipped open, or torn open, particularly preferably along a predetermined or perforated tear line 4G (see...). Figure 9AOpen, flip, or tear open the package 3 or outer package 4 to finally open the package or allow the workpiece 2 to be preferably retrieved from the flat side, such as Figure 9B As shown.

[0155] After the packaging 3 or outer packaging 4 is opened, or regardless of whether it is opened, the lateral clamping device is preferably reopened, or the retaining elements 136A, 137A or the adsorption members 136B, 137B are preferably flipped open again to facilitate the removal of the workpiece 2. However, during this process, the packaging 3 or outer packaging 4 is still preferably held by the retainer 202 or the adsorption member 202A.

[0156] The exposed workpiece 2 (preferably pointing upwards with its finished side 2B) can now be grasped by the delivery device 80 or the delivery robot 81 or the gripper 82 and transferred to the conveyor 10 or the waiting transport carrier 11.

[0157] The device 1 or opening station 200 preferably includes a packaging robot 204 to remove the empty package 3 or outer package 4 from the open position P9 and, for example, transfer the empty package 3 or outer package 4 to a receiving portion (not shown). For this purpose, the packaging robot 204 may have, for example, a pivot arm with an adsorption member 205 capable of moving particularly vertically, etc., as in... Figure 1 The text is only illustrative.

[0158] The particularly preferred aspects, variations, and method sequences of the invention will be emphasized and / or explained again below.

[0159] Preferably, the package 3 supplied by the conveying device 10 or the transport carrier 11 is picked up by the equipment 1 or the loading device 20. In particular, the package 3 is picked up by the equipment 1 or the loading device 20 from the loading position (the loading position is at...). Figure 1 (The middle section is shown as a transport carrier 11 with a package 3 on the right).

[0160] Optionally, particularly by means of the detection device 25, the markings 3A (especially barcodes and / or text descriptions) on the package 3 are detected or read, and / or preferably, the specific orientation of the supplied package 3 is detected according to the alignment or position of the markings 3A, particularly the specific orientation of the supplied package 3 in the transport carrier 11 and / or during transfer to position P1, according to the alignment or position of the markings 3A.

[0161] Typically, the marking 3A is provided on the side that needs to be opened (narrow side 4B, side flap 4D, or upper side 4E) at least to remove workpiece 2.

[0162] The loading device 20 preferably grasps the package 3 by means of a loading robot 21 or a loading suction member 22. More preferably, the loading device 20 grasps the package 3 on the flat side and / or the upper side 4E by means of the loading robot 21 and / or the loading suction member 22. However, the loading device 20 can also pick up or grasp the package 3 in other ways.

[0163] The loading device 20 and / or loading robot 21 can rotate the package 3 as needed, particularly about a vertical axis or an axis perpendicular to the bottom surface 4A of the outer package 4, to facilitate, for example, the subsequent opening of the side flap 4D to be opened.

[0164] The detection device 25 is preferably linked or connected to the loading robot 21 or the slider guide 24 of the loading robot 21. Therefore, in particular, when and / or after the package 3 is picked up by the loading robot 21 or the loading suction member 22, the mark 3A can be read and / or the package 3 can be rotated until it can be read and / or the package 3 is oriented in the desired manner.

[0165] Optionally, the package 3 is positioned, i.e., aligned, on one side, particularly on the narrow side 4B, and especially preferably on the two narrow sides 4B forming an angle of the outer package 4. Positioning and / or alignment can be achieved, particularly by means of the positioning device 30, and if necessary, depending on the design, positioning and / or alignment can also be achieved alternatively or additionally by means of the loading device 20 and / or the steering device 40.

[0166] Optionally, the package 3 can be rotated, specifically flipped, so that the upward-facing flat side can be rotated downward when needed. This is particularly useful for rotating the workpiece 2 contained in the package 3 with its processed side (i.e., finished side 2B) pointing upward, or for rotating the workpiece 2 in such a way that the workpiece 2 can be delivered at the end of the unpacking process, particularly preferably, at the end of the unpacking process, the workpiece 2 can be delivered from the equipment 1 or delivery device 80 with its finished side 2B facing upward, and in particular, at the end of the unpacking process, the workpiece 2 can be delivered again from the equipment 1 and / or delivery device 80 to the transport carrier 11 with its finished side 2B facing upward.

[0167] Particularly preferably, after being received into the device 1, the package 3 is first aligned and oriented, particularly by means of the positioning device 30, and then turned as needed.

[0168] The steering device 40 or its steering manipulator 41 may also be designed to maintain or achieve the desired alignment or positioning of the package 3, for example by the two gripping arms 42 being able to move symmetrically toward each other, or the two gripping arms 42 being able to move asymmetrically toward each other or toward each other only on one side, so as to grip the package 3 and align the package 3 if necessary.

[0169] The device 1 preferably includes different opening stations 100 and 200 for opening and / or unpacking different packages 3, especially different outer packages 4.

[0170] The transfer to the (first) opening station 100 is preferably achieved by means of a transfer robot 27, and / or by preferably vertically aligning the flat side of the package 3 or the flat side of the workpiece 2.

[0171] Preferably, the package 3 is transferred to the (second) opening station 200 by means of the feeding device 201, and / or by at least substantially horizontal alignment of the flat side of the package 3 or horizontal alignment of the workpiece 2.

[0172] It should be noted that, in this invention, "flat side" is understood to be the largest side or the side with the longest diagonal of the package 3 or outer package 4, which is preferably at least generally rectangular in shape.

[0173] In particular, package 3 or 4 can be selectively conveyed or supplied to one of the opening stations 100 or 200 depending on the packaging variant. More preferably, package 3 or 4 can be conveyed or supplied to one of the opening stations 100 or 200 from position P1 or from the defined alignment and pointing state of package 3, depending on the packaging variant.

[0174] In the (first) opening station 100, packages 3 and 4 are preferably opened on at least one side or narrow side 4B, particularly on the downward side or narrow side 4B and / or on the opposite side or narrow side 4B, and extremely preferably on both the downward narrow side 4B and the upward narrow side 4B.

[0175] Particularly preferably, the opening of the package 3 or the outer package 4 is achieved by mechanically engaging the side or side flap 4D to be opened from below, particularly by opening elements 111, 121, 131, wherein the side or side flap 4D can be opened simultaneously or sequentially, particularly by means of inclined planes or wedge-shaped surfaces 111A, 121A (particularly as in the first opening station 100), and / or particularly subsequently by pivoting of the opening element 131 (particularly as in the second opening station 200).

[0176] The opening elements 111, 121, 131 are configured, at least at their free ends and / or front ends, to be preferably at least generally flat and / or rounded, so as to facilitate lateral insertion under the side or side flap 4D to be opened, especially during the so-called opening movement B.

[0177] According to a particularly preferred aspect that can be implemented independently, the adjustment or feeding of the opening device or opening element can be optionally implemented, wherein the opening device and / or opening element is a second opening device 120 or a second opening element 121, so that, particularly after prior measurement or detection of the position of the side or side flap 4D to be opened or its edge 4H prior to opening, the side or side flap 4D to be opened can be reliably engaged from below by the opening element 121.

[0178] The term "engage from below" is generally understood to mean inserting the corresponding opening element (here, opening element 121) into the side or side flap 4D to be opened (particularly forming the narrow side 4B of package 3 or 4) between the package 4 and the narrow side 4B extending transversely to the side flap. The opening movement B or insertion movement is preferably parallel to the longitudinal extension direction of the side or side flap 4D to be opened or to the axis or edge 4H of the side or side flap 4D about which it is opened.

[0179] Particularly preferably, the distance A between the two opposing opening devices 110, 120 or between their opening elements 111, 121 is adapted to the detected actual internal distance I of the opposing side or side flap 4D to be opened, such as in Figure 4B The text is a schematic instruction.

[0180] Preferably, the orientation of workpiece 2 or the orientation of its flat side is detected.

[0181] Specifically, sensor 53A is used to detect whether blister 5A has been (correctly) received in the receiving position and how blister 5A is aligned (which side its open flat side or outlet points to).

[0182] Specifically, the degree of curvature (concave or convex) of workpiece 2 is detected by means of workpiece sensor 53B.

[0183] The orientation of workpiece 2 is derived from information from sensor 53A and / or workpiece sensor 53B. If necessary, workpiece 2 is then flipped, particularly by means of transfer robot 51.

[0184] The presence of an inner package 5 or its type can be reliably detected by means of (second) detection device 54 or cameras 54A and 54B.

[0185] After properly receiving the workpiece 2 with the inner packaging 5, the transfer robot 51 preferably grips the workpiece 2 in a sufficiently firm manner by the feed of the holding arm 52 in order to transfer the workpiece 2 to the next device, particularly preferably, whereby the workpiece 2 is transferred to different devices for selectively removing different inner packaging 5, such as selectively transferring the workpiece 2 to the separation device 60 or the unpacking device 70.

[0186] For the corresponding motion, the transfer manipulator 51 is preferably pivotable about a vertical and / or horizontal axis via one or more drive members 57 and can also extend or retract if necessary, particularly so that the workpiece 2 with the upward-pointing finished side 2B can be transferred. However, other structural solutions may also be adopted.

[0187] Particularly preferably, the device 1 can selectively detach or remove different internal packaging components 5.

[0188] The preferred method of removing the packaging tray or blister pack 5A from the workpiece 2, particularly by means of the separating device 60, is simple to implement. The lifting is particularly preferably achieved by means of a retainer or adsorption member 62, but in principle, the lifting can also be achieved by other operating members.

[0189] Conversely, removing the inner package 5 (particularly a folded cover) in the form of a wrapping layer 5B is methodically difficult. Experiments have shown that rolling the workpiece 2 at its edge (particularly preferably in conjunction with airflow and / or an adsorption mechanism 75) proves to be a very simple and effective method for separation.

[0190] The detached packaging layer 5B is preferably sucked away or removed by means of the adsorption mechanism 75 or otherwise. In particular, the unpacking device 70 or the rolling element 71 has a corresponding cover, on the one hand to achieve the desired airflow, air guidance and / or adsorption in the tilted state or in the working position, and on the other hand to enable the workpiece 2 with the inner packaging 5 or the packaging layer 5B to be placed into the rolling element 71, especially by means of the transfer device 50, in the descending position or changing position.

[0191] Preferably, workpieces 2 that have been unpacked by different devices can be picked up and re-output by means of a shared delivery device 80 or a shared gripper 82, particularly to an empty transport carrier 11 or the original transport carrier 11, preferably having a corresponding information carrier, and particularly preferably output with the finished surface 2B pointing upwards.

[0192] Preferably, the multiple positions of the packaged workpiece 2, namely positions P6, P8, and / or P9, are arranged in a straight line, so that the delivery device 80 can pick up and output the workpiece 2 through different positions by means of the linear guide 83. In particular, the delivery device 80 can output the workpiece 2 to the conveying device 10 or the transport carrier 11 (which is specifically in the receiving position or in the...). Figure 1 The left-hand position in the picture is different from the position when the packaged workpiece 2 was supplied.

[0193] Particularly preferably, the lines of receiving positions P6, P8 and / or P9 extend transversely to the conveying direction X. In particular, the lines of receiving positions P6, P8 and / or P9 extend perpendicularly to the conveying direction X. In the illustrated example, the lines of receiving positions P6, P8 and / or P9 extend in the Y direction.

[0194] In the (modified or second) opening station 200 or opening device 130, the side or side flap 4D of the package 3 or outer package 4 is preferably opened by pivoting via the opening element 131 and / or the clamping device formed therefrom. In particular, this is a common alternative method of folding or opening via an inclined plane, and the above-described solution can also be implemented in a manner independent of other aspects and features and / or in combination with other aspects and features.

[0195] Another aspect that can be achieved independently is that the side or part of the outer packaging 4 is automatically torn open, in particular along the set weakening line, predetermined break point, perforation or tear line 4G.

[0196] Particularly preferred is a combination of clamping and gripping a portion of the outer packaging 4, followed by tearing open the connected area. Specifically, the connected area is either the flat side or the upper side 4E of the outer packaging 4. Alternatively, only a portion of the flat side or the upper side 4E may be opened or torn open and flipped open.

[0197] Extremely preferably, the side flap 4D is first opened and / or flipped open, and then the side or top 4E of the outer packaging 4 connected to the side flap 4D to be opened is torn open.

[0198] In opening station 100, the direction of opening movement B (i.e., the relative movement between packages 3, 4 and opening devices 110, 120, 130) is preferably horizontal and / or extends along the Y direction or laterally to the conveying direction X, and in opening station 200, the direction of opening movement B is preferably horizontal and / or parallel to the conveying direction X and / or laterally to or perpendicular to the opening movement B of opening station 100.

[0199] Preferably, the positioning device 30, the steering device 40, the separating device 60, the unpacking device 70, and / or the (second) opening station 200 are arranged at least generally in the lower plane and / or a common plane and / or at approximately the same height as the conveying device 10. The (first) opening station 100 is preferably arranged at least generally in the plane above it or in a higher plane. This facilitates a compact structure of the device 1.

[0200] The device 1 is preferably configured to automatically remove the workpiece 2 from different outer packages 4 and / or inner packages 5, wherein the means required for this purpose are preferably or at least substantially all housed in a common frame or housing 1A.

[0201] Preferably, the term "adsorption component" should generally be understood as an operating component that operates under negative pressure.

[0202] However, it should be noted that other clamping or retaining components can usually be used in place of the adsorption component, depending on the requirements, even if not explicitly mentioned in each case.

[0203] The following will refer to Figure 10 The second embodiment of the proposed device 1 and the proposed method for removing the optical workpiece 2 (particularly a lens blank for spectacle lenses) from the package 3 is described with reference to the accompanying drawings.

[0204] In the following description, in particular, only the differences and new aspects, features and advantages will be discussed in detail first, wherein the foregoing descriptions and explanations are applied in a corresponding and / or supplementary manner, so that the corresponding features and advantages are obtained even if repeated descriptions are omitted.

[0205] Figure 10 A schematic top view of device 1 according to the second embodiment is shown.

[0206] In a second preferred embodiment, the device 1 and method are preferably configured such that every two packaged workpieces 2 or eyeglass blanks (potentially) are unpackaged simultaneously. Therefore, preferably, the two packages 3 are always opened in parallel or simultaneously. This allows for a particularly high throughput, preferably exceeding 500 pieces per hour, and particularly, approximately 600 pieces or more per hour.

[0207] However, in principle, as in the first embodiment, the packaged workpieces 2 or packages 3 can be opened one by one. In particular, the packaged workpieces 2 or packages 3 are picked up from the conveying device 10 or transport carrier 11 and then opened sequentially. The following descriptions and explanations also apply accordingly.

[0208] According to the second embodiment, the device 1 preferably further includes, or similarly includes, a conveying device 10, a loading device 20, a positioning device 30, a turning device 40, a (first) opening station 100, an additional opening device 140, a (second) opening station 200 or another opening station 130, a transfer device 210, a separation device 60, a delivery device 80 and / or a return device 90.

[0209] In the second embodiment, the conveying device 10 is preferably configured to at least substantially correspond to the first embodiment.

[0210] The device 1 or its loading device 20 is preferably configured to simultaneously grab or lift two packaged workpieces 2 or packages 3, particularly from the transport carrier 11.

[0211] The loading device 20 for simultaneously gripping two packages 3 preferably includes two correspondingly spaced loading manipulators 21, which are located at corresponding gripping elements or loading adsorption components 22.

[0212] Specifically, the positioning device 30 is arranged above the conveying device 10, and / or the positioning device 30 is movable. Particularly preferably, the positioning device 30 can move along the conveying device 10 or in the X direction, and / or the positioning device 30 can move below the loading device 20 or one or more of its loading manipulators 21, so that the package 3, when lifted from the conveying device 10 or the transport carrier 11, can be placed directly on the positioning device 30 or its support surface 33 by descent. However, other structural solutions are also possible.

[0213] In the second embodiment, preferably, the vertical slider guide 24 for loading the robotic arm 21 or the vertical lifting of the package 3 to be opened is sufficient to place the package 3 on the preferably movable positioning device 30. However, other structural solutions are also possible.

[0214] In the second embodiment, preferably, the effect of centering the corresponding package 3 is that the corresponding package 3 is placed in a specific position with the center of the flat side, that is, the package 3 is centered.

[0215] Furthermore, the package 3 is preferably aligned horizontally by its flat side and positioned in the desired rotational position, particularly such that one side extends parallel to the X-axis of the conveyor 10 or the conveying direction. However, other alignment methods may also be used in principle.

[0216] In the second embodiment, the positioning device 30 of the device 1 preferably has two positioning elements 31 and 32 for each package 3 that needs to be positioned, wherein the positioning elements 31 and 32 are preferably fed symmetrically to each other, in particular along the diagonal of the package 3 or the angle bisector of the XY plane, so as to center the package 3 in a desired manner.

[0217] Due to the preferred angular structure of the two positioning elements 31 and 32, which engage at opposite corners of the package 3, the package 3 can thus be aligned in a desired manner in its rotational position (around the Z-axis or vertical axis) and can also be centered in a desired manner simultaneously by the opposing feeds of the positioning elements 31 and 32.

[0218] The positioning device 30 preferably has a particularly horizontal support surface 33 on which packages 3 that are not yet aligned or positioned can be placed by means of the loading device 20. Figure 10 The positioning device 30 is shown, which has only one unpositioned or uncentered package 3 located on the left. For ease of illustration, the common second package 3 located on the right is omitted from the figure.

[0219] Subsequently, the package 3 is centered using a positioning device 30, preferably in pairs or simultaneously. Specifically, centering is achieved by symmetrically feeding two positioning elements 31 and 32, each belonging to the same package 3. Figure 10 In the positioning device 30, the transfer position P1 is marked with a dashed line on the right side. Particularly preferably, the transfer position P1 is the position of the package 3 after centering, and / or the position from which the package 3 leaves when it is preferably taken away again. Similarly, this also preferably applies to the other side.

[0220] Particularly preferably, the packages 3 (especially by means of the positioning device 30) are positioned and / or centered at a greater distance than on the conveying device 10 or transport carrier 11. This increased distance facilitates the opening of the two packages 3 in parallel, especially when the sides or side flaps 4D that point opposite to each other (as preferably specified in the second embodiment) are also opened or flipped open.

[0221] In the second embodiment, the loading device 20 or the loading robot 21 is not configured to rotate the package 3. Preferably, rotation is performed only after the package 3 has been positioned and aligned or centered.

[0222] After positioning / centering the package 3, the transfer robot 27 (see...) Figure 11The robotic arm picks up package 3, and preferably has two holding members (particularly transfer adsorption member 28) to pick up package 3 from positioning device 30 and / or transfer package 3 to turning device 40 or opening station 100 or transfer position P2 (see Figure 10 ).

[0223] Preferably, the transfer robot 27 is offset relative to the loading device 20 or the loading robot 21 in the X and / or Y directions.

[0224] In order to pick up the centered package 3, in the second embodiment, preferably, the positioning device 30 is positioned below or in front of the transfer robot 27, or the positioning device 30 is moved in the X direction or moved to the delivery position or transfer position P1 (see...). Figure 10 ), so that package 3 can be transferred to transfer robot 27.

[0225] In the second embodiment, the transfer manipulator 27 is preferably arranged separately from the loading device 20 or its loading manipulator 21, particularly positioned laterally or offset in the X direction, since the positioning device 30 is preferably capable of displacement or movement accordingly. However, other structural solutions are also possible.

[0226] according to Figure 10 As shown, the positioning device 30 is positioned at the extension and / or front of the transfer robot 27, the steering device 40, and the opening station 100. For clarity, Figure 10 The transfer robot 27 and its motion mechanism 29 are not shown in the diagram, but are only shown in the diagram. Figure 11 As shown in the 3D diagram. However, in Figure 11 In this case, the positioning device 30 is not located at the transfer position P1, but at the picking position below the loading robot 21 used to pick up the package 3.

[0227] In the illustrated example, the transfer manipulator 27 moves preferably horizontally in the Y direction or laterally to the transport direction X and / or vertically by means of the motion mechanism 29 or the corresponding slider guide, wherein, preferably, the holding member or the transfer adsorption member 28 can rotate about the central axis or the vertical axis respectively and independently of each other.

[0228] The transfer robot 27 or its holding member is preferably configured such that, after the package 3 has been lifted or is left idle, the package 3 can be rotated as needed and / or independently of each other, particularly in 90° increments, in order to achieve the desired alignment of the package 3 very quickly and in a defined manner.

[0229] According to the second embodiment, the device 1 preferably further includes a detection device 25 for detecting or reading the mark 3A on the package 3, and therefore reference can be made to the above description related to the first embodiment.

[0230] By means of the rotatable holding member or transfer adsorption member 28 of the transfer manipulator 27, the package 3 can be rotated around its main axis or around a preferred vertical axis of rotation, and the correct or desired rotational position of the package 3 can be reached accordingly by means of the detection mark 3A.

[0231] In order to receive and transfer the package 3, the transfer robot 27 is preferably liftable, that is, the transfer robot 27 can move in the vertical direction or the Z direction, and preferably can also move in the horizontal direction or the Y direction or transverse to the conveying direction of the conveying device 10.

[0232] Therefore, in the second embodiment, it is not specified that the package 3 is pivoted around a horizontal axis by means of the transfer robot 27.

[0233] The transfer robot 27 transfers the package 3 to the turning device 40 or the opening station 100 or the opening robot 101 of the opening station 100. Figure 10 and Figure 11 Only package 3 or location P2 on the right side of the schematic seismic intensity map is marked.

[0234] In the second embodiment, preferably, the package 3 is opened by horizontally aligning the bottom side or bottom surface 4A of the outer package 4. It may be necessary to flip the package 3 around a horizontal axis. This is illustrated by marking 3A as "inverted."

[0235] The turning of package 3 is optionally performed in a turning device 40, preferably located downstream, where the transfer robot 27 transfers the two packages 3 to the turning device 40 in a centered state and in a manner aligned in the desired rotational position.

[0236] Preferably, the steering device 40 is provided with two receiving areas and two steering manipulators 41. In particular, the two steering manipulators 41 have clamp-like gripping arms 42 so as to lift the package 3 and turn it (especially about the horizontal axis) when needed. In this case, the package 3 is kept in a fixed-center state.

[0237] According to the second embodiment, preferably, the package 3 is first opened laterally in the first step; specifically, the package 3 is first opened laterally on the opposite side or the side flap 4D. Preferably, the above process is achieved by means of an opening station 100.

[0238] In the second embodiment, preferably, after the package 3 is opened laterally in the opening station 100, the upper side 4E of the package 3 or the outer package 4 is preferably opened or flipped open in the second step, and particularly, after being opened laterally in an intermediate step, the upper side 4E of the package 3 or the outer package 4 is preferably opened or flipped open in the second step.

[0239] Preferably, the device 1 or the opening station 100 has a first opening device 110 and a second opening device 120 for each package 3, so as to open the package 3 from opposite sides respectively. Unlike the first embodiment, in the second embodiment, opening is preferably achieved by horizontally aligning the bottom side 4A or the package 3.

[0240] Preferably, the device 1 or the opening station 100 includes a modified opening robot 101 to transfer or move the package 3 from the turning device 40 and / or along the opening devices 110, 120 and / or to the intermediate station or the transfer device 210.

[0241] In the illustrated example, the opening robot 101 preferably has a receiving portion 107 for the package 3, that is, preferably has two receiving portions 107 for receiving two packages 3 to be opened in a parallel manner.

[0242] according to Figure 12 and Figure 13 This allows for a better view of the optimal design of the opening station 100 or the opening robot arm 101. Figure 12 and Figure 13 The components of the device 1 or the opening station 100 are shown from different perspectives, particularly the opening manipulator 101 with two receiving parts 107. Preferably, the opening manipulator 101 can move along the guide track 102 or in the Y direction or in a straight line or horizontally.

[0243] Preferably, the receiving portion 107 forms a horizontal support, and / or in the illustrated example is configured preferably at least generally U-shaped, and / or is provided with an adsorption member 108 so as to receive the package 3 to be opened in a horizontally aligned manner, and in particular hold it from the bottom side.

[0244] Preferably, the receiving portion 107 is provided with a one-sided or rearward (especially upright) stop 109 so that the package 3 can be securely held or supported and guided in the direction of movement B in a form-fitting manner at the narrow rear side when moving through the opening devices 110, 120.

[0245] Preferably, the steering device 40 or its steering manipulator 41 is designed such that the clamping arms 42, capable of feeding in a pincer-like manner and particularly in a symmetrical manner, can laterally surround the upright stop 109, such as Figure 10 As shown, before the corresponding package 3 is transferred to the receiving part 107 or the robot arm 101 is opened, the corresponding receiving part 107 can move with its stop 109 toward the narrow side of the package 3 pointing toward the conveying device 10 in the illustrated example.

[0246] Alternatively, the package 3 can be held or positioned by the transfer robot 27 to ensure that the stop 109 abuts against the package 3, thereby ensuring that the package 3 is held in a defined manner when it is opened laterally.

[0247] Preferably, the opening manipulator 101 or receiving portion 107 can move from the receiving position P2 (particularly in the turning position 40, i.e., the position where the package 3 is transferred by the transfer manipulator 27, especially for opening the package 3 on the opposite sides) along the opening devices 110 and 120 (preferably linearly and particularly along the guide track 102) to the intermediate station or transfer device 210 or the transfer position here. During this opening movement or movement direction B, preferably, the two opposite sides or side flaps 4D of each package 3 are opened simultaneously.

[0248] Preferably, the two opening devices 110 and 120 are not offset in the direction of the opening movement B, that is, there is no offset V as in the first embodiment.

[0249] Figure 14 The device 1 is shown in a schematic top view, with the opening manipulator 101 positioned in the center, and the receiving portion 107 located precisely between the opening devices 110 and 120 or between the opening elements 111 and 121. For simplicity, only one package 3 is shown here, namely the package on the right side of the two parallel opening paths. Furthermore, only in this schematic view, the opening elements 111 and 121 associated with the package 3 are not shown to be correctly engaged with the package 3, but rather spaced apart from it. In this state, the package 3 must have been opened laterally, specifically by means of the upward-folding side cover 4D, which in the correct schematic would correspondingly cover the opening elements 111 and 121.

[0250] Preferably, as in the first embodiment, device 1 or open station 100 also uses measuring device 104 (see... Figure 12 and Figure 13 Specifically, the measuring device 104 is in the form of a camera or a tactile sensor for detecting the dimensions (particularly the width) of the package 3.

[0251] Because of the center alignment of package 3, a single-sided inspection of one side of package 3 is sufficient to infer the size of package 3 and / or the position or location or spacing of the opposite side flap 4D to be opened.

[0252] Therefore, specifically, two measuring devices 104 are sufficient for two opening paths with two packages 3. However, two measuring devices 104 can also be assigned to each package 3 or each opening path respectively, in order to measure the adjustment direction R with particular precision. Figure 10 Alternatively, detect the position or location of each side to be opened in the horizontal direction or the X direction in the diagram.

[0253] The two opposing opening devices 110 and 120, or their opening elements 111 and 121, can be adjusted or modified by means of a preferred common adjusting device 103, particularly in terms of their position or spacing in the horizontal direction, such that the opening elements 111, 121 engage the respective side flaps 4D from below during the movement of the package 3, and the side flaps are opened by the preferred wedge shape or bevel of the opening elements 111, 121.

[0254] In the second embodiment, preferably, both the first opening device 110 and the second opening device 120 are adjustable (here, along a preferred horizontal adjustment direction R), and preferably, the first opening device 110 and the second opening device 120 are symmetrical to each other, since the respective packages 3 to be opened are guided along a central line or in a centered manner. Specifically, the adjusting device 103 includes a threaded spindle for adjusting the two respective opening devices 110 and 120 together in opposite directions. However, other structural solutions are also possible.

[0255] In the second embodiment, preferably, parallel (extending along the Y direction in the illustrated example) movement paths are formed in the opening station 100 for two packages 3 to be opened simultaneously, or preferably for opening corresponding opposite sides simultaneously. Each opening path is respectively assigned a first opening device 110 and a second opening device 120. Preferably, these paired opening devices can be individually adjusted to or adapted to the size of the corresponding package 3, and preferably, each opening device is provided with its own adjustment device 103.

[0256] In the illustrated example, preferably, it is folded upwards, that is, in particular, so that the side fold cover 4D is suspended on the corresponding upper side 4E.

[0257] The opened package 3 is transferred from the opening robot 101 to the intermediate station of the equipment 1 or the transfer device 210 or the receiving table 211 of the transfer device 210.

[0258] Figure 14 The receiving device 210 or its receiving platform 211 is shown in a transfer position for receiving a package 3 that has been opened laterally.

[0259] In particular, the transfer device 210 can also perform the function of the feeding device 201 according to the first embodiment, and is specifically assigned to the opening station 200 or another opening device or the third opening device 130. However, in principle, the transfer device 210 can also be a completely independent device.

[0260] In the illustrated example, in particular, an additional or third opening device 130 is arranged at the transfer device 210 or on its receiving platform 211. However, other structural solutions are also possible.

[0261] Alternatively or additionally, preferably, in the illustrated example, the transfer device 210 also cooperates with an additional opening device 140, or is used to move or transfer the package 3 to the additional opening device 140 and / or opening station 200 and / or separation device 60 and / or return device 90.

[0262] Preferably, the transfer device 210 includes a guide rail 212 or other guide with a corresponding drive, which is specifically used to move the receiving table 211, particularly linearly, to the desired position. The direction of movement extends, preferably horizontally, in the X direction parallel to the conveying direction of the conveying device 10 and / or laterally to the opening path of the opening station 100.

[0263] Preferably, the receiving table 211 has a recess 213 into which the receiving portion 107 can move into, so as to transfer the side-opened package 3.

[0264] The package 3 extends out of the receiving portion 107 in a preferred lateral manner through the bottom surface or bottom side 4A of the package 3, so that the package 3 can be received or held by the receiving table 211.

[0265] Preferably, adsorption members 214 are centrally arranged in the recesses 213 of the receiving table 211 so as to hold the package 3 on the receiving table 211.

[0266] Specifically, the receiving portion 107 can move into the recess 213 via its extended legs, so that the adsorption members 214 are respectively received between them, especially in order to subsequently hold the corresponding package 3 on the receiving table 211.

[0267] Alternatively or additionally, the receiving platform 211 and the receiving section 107 may also vary in height relative to each other to ensure stable transfer of the package 3.

[0268] Alternatively or additionally, the transfer can be supported or secured by additional holding or clamping of the package 3 on the transfer device 210 or the receiving table 211, as will be explained in more detail below.

[0269] Figure 15 An opening robot 101 in a transfer position is shown, used to transfer package 3 (not shown) to transfer device 210 or receiving table 211. Receiving portions 107 move into corresponding recesses.

[0270] Preferably, the receiving table 211 has a bevel on its edge pointing toward the opening manipulator 101, which ensures that the package 3 is pushed upward onto the receiving table 211 in a defined manner or facilitates transfer.

[0271] Preferably, the device 1, the feeding device 211, or the receiving table 211 is provided with a holding element or a pivoting element 215 so that the package 3 can also be held on the receiving table 211 from above, and / or so that the package 3 can be opened from above or from its flat side or upper side 4E. The above will be explained in more detail later.

[0272] Preferably, the pivoting element 215 is provided with two arms 216 and / or one or more adsorption members 217, and / or can pivot from above onto the package 3 (not shown), particularly by means of a corresponding drive member, so as to securely hold the received package 3 on the receiving table 211.

[0273] After the packages 3 are opened laterally on opposite sides, and preferably after transfer (in an intermediate step or at an intermediate station), these packages 3 are preferably additionally opened, separated or cut so that the upper side 4E can be turned up.

[0274] Preferably, the additional opening, cutting, or separation is performed on the bottom side, i.e. on the base side or bottom surface 4A of the outer packaging 4 and / or particularly preferably near the narrow side 4B or edge, and / or on the entire extension of the packaging 4 or on the narrow side 4D or on the bottom side 4A located between the opposing (preferably already opened or needing to be opened) sides of the packaging 4. Thus, in the illustrated example, the additional opening, cutting, or separation is performed in the X direction.

[0275] For additional opening, separation, or cutting, preferably, device 1 or intermediate station includes an additional opening device 140, preferably in the form of a cutting device, specifically having a rotating blade 141, as in... Figure 10Only illustrative markings are shown in the text.

[0276] Preferably, the cutting device or its blade 141 is movable relative to the package 3 or the receiving table 211 in the cutting direction, which is the X direction.

[0277] In the illustrated example, preferably, the feeding device 210 or the receiving table 211 can move in the X direction from a transfer position for receiving the package 3 to a conveying position (e.g., Figure 10 As shown), the conveying position is used to fully open or flip over the package 3.

[0278] The aforementioned movement can be used for relative movement between the additional opening device 140 or cutting device and the package 3, for cutting the package 3. In this case, the additional opening device 140 or cutting device is arranged in a particularly fixed manner, especially preferably such that the package 3 moves past (here, from the receiving table 211) Figure 14 The indicated transfer position is moved to Figure 10 During the transport phase shown, the section is automatically cut in the desired manner. However, other structural solutions are also possible.

[0279] However, it is also possible, for example, that the opening device 140 or the cutting device can move along the package 3 in a desired manner. Therefore, a variety of structural solutions can be adopted here.

[0280] It should be noted that package 3 does not necessarily have to be cut open from the bottom. Alternatively, in principle, package 3 can be torn open, for example, along a predetermined tear line, through a perforation, etc.

[0281] Alternatively, the cut may be made on the still-closed narrow side 4B or generally in the area of ​​the (narrow side or still-closed) end of the package body 3, 4.

[0282] Importantly, the package 3 is opened, separated, or cut in the area of ​​the transverse side or narrow side 4B that is still closed between the two opposing narrow sides of the package 3 that have been opened or still need to be opened, so that the upper side 4E is subsequently connected to the bottom side and / or bottom surface 4A of the outer package 4 only on the other narrow side and can be easily (especially upward) turned open accordingly.

[0283] In principle, the package 3 can also be opened or cut from the bottom side or horizontally before the side fold cover 4D is opened.

[0284] In principle, the package 3 can also be opened by cutting it laterally, that is, by cutting the package 3 on the opposite narrow side, for example by means of the first opening device 110 and the second opening device 120, or by other means, instead of flipping open the side flap 4D.

[0285] Preferably, the device 1 or transfer device 210 or pivot element 215 is configured such that the corresponding package 3 (especially on the receiving table 211) is preferably held in a clamping and / or fixed manner, so as to be cut in the lateral direction (i.e., in this case, along the X direction or between two open, opposite narrow sides) or opened in some other way.

[0286] In the illustrated example, preferably, the pivot element 215 has two arms 216 and / or one or more adsorption members 217, particularly each arm 216 or each package 3 corresponds to multiple adsorption members 217, so as to securely and rotatably fix the package 3 in a desired manner.

[0287] After the opposite narrow side is opened (preferably by flipping open the side flap 4D) and after opening or separating the package 3, 4 in the still closed narrow side end area or the still closed lateral side or narrow side 4B area (preferably by cutting from the bottom side by means of the cutting device 150), the package 3 is preferably fully opened by flipping open the upper side 4E.

[0288] Preferably, the device 1, the transfer device 210, or the pivot element 215 is configured to open or flip open or turn upwards the upper side 4E or other flat side of the package 3 or the outer package 4.

[0289] Specifically, the transfer device 210 here also forms an additional opening device 130 and / or (second) opening station 200. Conversely, the opening device 130 and / or opening station 200 can also be understood to include the transfer device 210.

[0290] In the illustrated example, preferably, the package 3 is fully opened or the upper side 4E is flipped open at the aforementioned transfer position. Figure 10 The transfer position is specifically achieved by moving the feeding device 210 or the receiving table 211 with the packaging 3 from the receiving position to the transfer position (here, by moving in the X direction). However, if the cutting or opening has already been performed in this position between the opposite open sides, the opening of the upper side 4E can also be performed in principle in the transfer position.

[0291] To open, the pivoting element 215 preferably pivots, particularly upwards, wherein the package 3 or the upper side 4E of the package 3 is held and thereby driven by one or more suction members 217, such as Figure 16 As shown. However, other structural solutions are also possible.

[0292] In the second embodiment, preferably, the device 1 or its delivery device 80 and / or its separation device 60 are also configured such that two workpieces 2 and / or inner packages 5 can be removed simultaneously or in parallel from the two opened packages 3. In particular, two parallel removal paths are formed, which are spaced apart from each other, enabling the removal of the workpieces 2 and (if necessary) the inner packages 5.

[0293] Specifically, the removal path extends parallel to the opening path of the already mentioned opening station 100, but in the opposite direction.

[0294] Preferably, the lens or workpiece 2 points from its finished side 2B to the opened flat side or upper side 4E. (According to...) Figure 2A , Figure 2B and Figure 2C In contrast to the illustration, in this case, workpiece 2 is preferably oriented in the opposite manner. According to... Figure 2A In the case of a variant of the implementation, specifically, the blister 5A is correspondingly fitted from above to cover the finished side 2B. Correspondingly, according to... Figure 5 In the case of a variant of implementation C, the inner layer structure 5C holds the workpiece 2, preferably by partially overlapping the finished side 2B located above, or by protecting the finished side 2B from scratches in the package 3.

[0295] Therefore, the removal and separation of workpiece 2 is preferably carried out in a lateral offset relative to the lateral opening of package 3 (i.e., offset in the X direction). More specifically, workpiece 2 is preferably moved back toward conveyor 10 in the opposite direction to the lateral opening of package 3, so as to achieve an optimized process and compact structure of device 1.

[0296] In the second embodiment, preferably, the delivery device 80 or its delivery robot 81 has two or more retaining arms 82 as retaining members, so as to preferably grip or hold the workpiece 2 from the edge side.

[0297] When workpiece 2 is fully opened after packaging 3 is opened, particularly when it is exposed after the upper side 4E is opened (especially with the upward-pointing finished side 2B), workpiece 2 is grasped or held by delivery device 80 or delivery robot 81 (especially from above), and workpiece 2 is transferred again to conveyor 10 or transport carrier 11, especially the original transport carrier 11 that has already transported the packaged workpiece 2. As mentioned above, it is preferable to take out and transfer two workpieces 2 in parallel or simultaneously. Correspondingly, device 1 or delivery device 80 preferably has two delivery robots 81, in particular, these two delivery robots 81 are connected to a common slider guide, etc., preferably, each delivery robot 81 has two holding arms 82. However, other structural solutions are also possible.

[0298] In the illustrated example, preferably, the retaining arm 82 is provided with two abutment areas or abutment protrusions 82A, and / or is designed to be slightly curved so that it can abut against the workpiece 2 at two circumferentially spaced locations, thereby firmly holding the workpiece 2.

[0299] Preferably, the delivery robot 81 or its holding arm 82 can rotate about a central axis (preferably a vertical axis). Figure 16 (Exemplary example shown at the delivery robot 81 on the right side). Therefore, in some cases, the inner package 5, which is laterally engaged with the workpiece 2 or even partially spans the workpiece, can be pressed away radially outward by rotating about the aforementioned axis.

[0300] Preferably, the delivery robot 81 with the open retaining arm 82 is first moved between the inner package 5 or inner structure 5C, and then the delivery robot 81 is rotated at a certain angle, particularly about 45°, to slightly compress the inner package or inner structure 5C radially outward. Subsequently, the retaining arm 82 is closed and the workpiece 2 is gripped and removed from the package 3, particularly by lifting.

[0301] Preferably, the delivery device 80 or its delivery robot 81 is configured to move in the vertical or Z direction and in the horizontal direction (especially the Y direction) to transfer the workpiece 2 from the package 3 to the conveying device 10 or the desired transport carrier 11 in a desired manner. For example, this process can be achieved by a horizontal guide or slider guide 83 and a corresponding lifting device 84, etc.

[0302] Particularly preferably, the two delivery robots 81 can move or be positioned together, particularly vertically, via a lifting device 84 (e.g., a shared slider). However, they can also move vertically and / or horizontally, for example, individually or independently of each other.

[0303] In the illustrated example, the package 3 and the workpiece 2, whether in the opening station 200, in the conveying device 210, on the receiving table 211, or in a state where they are opened or flipped open by the opening device 130, preferably still have the spacing set by the opening station 100 or when the opposite side is opened and / or increased relative to the original spacing in the transport carrier 11.

[0304] Particularly preferably, the device 1 or delivery device 80 is configured such that the removed or unpackaged workpiece 2 can be retransferred to the desired transport carrier 11 at its original spacing. During the simultaneous processing of two workpieces 2 by means of preferably two delivery robots 81, they are preferably adjustable relative to each other in a corresponding manner. Specifically, a lateral adjustment device 85 is provided for this purpose, by means of which the two delivery robots 81 can (preferably symmetrically) move towards each other, or at least one delivery robot 81 can be adjusted relative to the other. However, other structural solutions are also possible. The lateral adjustment device 85 is configured according to… Figure 18 The three-dimensional diagram is shown.

[0305] Depending on throughput and operating speed, the delivery device 80 can, in principle, operate with only one delivery robot 81. Specifically, the acceptance and transfer of workpieces 2 will be carried out one at a time. In this case, intermediate storage may be advantageous so that the transfer device 210 or its storage platform 211 can be unloaded at the delivery location as quickly as possible.

[0306] Preferably, the delivery device 80 or the delivery robot 81 is equipped with a detection device, specifically, the detection device is a camera or the like. Figure 17 The detection area 86 is shown in the diagram so that it can detect whether the workpiece 2 has actually been removed from its packaging, i.e., whether its facing side is exposed, before it is grasped or clamped.

[0307] In the illustrated example, specifically, the detection device or camera is centrally positioned on the delivery robot 81 or between the holding arms 82. However, other structural solutions are also possible.

[0308] If the packaging 3, which serves as the inner packaging 5, has a particularly flexible wrapping layer 5B, then preferably the wrapping layer 5B is unfolded or opened and / or sucked away or removed by a compressed air supply mechanism and / or an adsorption mechanism 75.

[0309] Figure 14 An adsorption mechanism 75 is shown, which is preferably arranged in the area of ​​the conveying position. Figure 16The adsorption mechanism 75 and the corresponding conveying device 210 or the corresponding support platform 211 are shown in a schematic perspective view, wherein the opened package 3 is in the conveying position, and in particular, for ease of explanation, the separation device 60 and other components of the equipment 1 are omitted.

[0310] Particularly preferably, the device 1 and / or the adsorption mechanism 75 has at least one adsorption opening 75A. Preferably, the adsorption opening 75A can be moved to the adsorption position as needed. Particularly preferably, the adsorption opening 75A can be moved to the area of ​​the conveying position as needed.

[0311] Specifically, the adsorption mechanism 75 or adsorption opening 75A can be moved next to and arranged adjacent to the opened package 3 so that the wrapping layer 5B can be opened or kept open when needed, and / or the wrapping layer 5B can be sucked up and thus removed (especially after picking up or removing the workpiece 2). However, other structural solutions are also possible.

[0312] In the second embodiment, preferably, the adsorption mechanism 75 has at least two adsorption openings 75A so that it can be used to open or unfold the wrapping layer 5B for each of the two packages 2 that are opened at the same time, and (if necessary) can also suck up the wrapping layer 5B.

[0313] After the wrapping layer 5B is opened or unfolded, as previously mentioned, preferably, the workpiece 2 can be directly grasped and picked up by the delivery device 80 or the delivery robot 81 or the holding arm 82 of the delivery robot 81, and transferred to the conveying device 10 or the desired transport carrier 11 in a desired manner.

[0314] In the second embodiment, if the workpiece 2 is packaged in an inner package 5 in the form of a packaging tray or blister pack 5A, it is preferable that the workpiece 2 can also be removed from the packaging.

[0315] Preferably, the device 1 or its separation device 60 or the separation manipulator 63 of the separation device 60 is configured such that, in particular, when the upper side of the workpiece 2 is covered by the inner packaging 5 or the packaging tray or blister pack 5A, the workpiece 2 can be removed (in particular pulled out) together with the inner packaging 5. Preferably, the flat side 2A located at the bottom is configured to be concave, such that it rests against the bottom only by its edge.

[0316] Since the package 3 (more precisely, the outer package 4) that is opened according to the suggestions of this application is also open forward or on multiple sides (in this case, even three sides), it can be pulled out in a very easy manner. Figure 18 The starting positions of two packages 3 and one workpiece 2 are shown in the figure.

[0317] In the illustrated example, preferably, the workpiece 2 with the blister pack 5A is pulled into the receiving area 61 via the intermediate plate 66. Particularly preferably, this is achieved by means of a separation device 60, which engages the separation manipulator 63 from above via the suction member 64, and pulls the inner package 5 together with the workpiece 2 below it into the receiving area 61 via the intermediate plate 66. However, other structural solutions are also possible.

[0318] In the receiving area 61, preferably, the separation of the package 5 and the workpiece 2 is achieved by removing the inner package 5 or the blister pack 5A, such as... Figure 19 As shown in workpiece 2.

[0319] In the second embodiment, particularly preferably, the device 1 or the separation device 60 also has a retainer or adsorption member 62 in the receiving area 61 to retain the workpiece 2, especially when the inner package 5 or the packaging tray 5A / blister 5A is removed.

[0320] Therefore, in the illustrated example, preferably, the separation manipulator 63 or each separation manipulator 63 can pivot via its adsorption member 64, preferably about a horizontal axis, particularly extending in the X direction.

[0321] Preferably, the device 1 or the separation device 60 has two separation manipulators 63, which preferably operate independently of each other and / or are capable of pivoting about a preferred horizontal axis, particularly extending in the X direction and / or a common axis, particularly independently of each other, and / or the two separation manipulators 63 can be particularly jointly adjusted and / or moved, particularly preferably, the two separation manipulators 63 can be jointly adjusted and / or moved by means of an adjustment device 66, and / or the two separation manipulators 63 are preferably configured as arms and / or each has an adsorption member 64 at its free end.

[0322] After the packaging pallet 5A is removed by the separation device 60 or the separation robot 63, the workpiece 2 is openly located in the receiving area 61 and can be grasped by the delivery device 80 or its delivery robot 81 and transferred in the desired manner to the conveying device 10 or the transport carrier 11.

[0323] Typically, workpiece 2 is positioned with its processed flat side (i.e., finished side 2B) facing upwards or towards the upper side 4E of package 4. Correspondingly, workpiece 2 is also transferred from delivery device 80 to conveying device 10 or transport carrier 11 with finished side 2B facing upwards.

[0324] If workpiece 2 is placed in an opened package 3 or packaging pallet 5A with its finished side 2B facing down, workpiece 2 can optionally be turned using a separation device 60. For this purpose, the separation device 60 or its separation manipulator 63 grasps workpiece 2 on the upper, unprocessed, flat side 2A via an adsorption member 64. Workpiece 2 is then flipped over by pivoting 180° around this preferably horizontal pivot axis by the separation manipulator 63, and can then be directly grasped by the delivery device 80 or delivery manipulator 81 and ultimately transferred to the conveyor 10 or transport carrier 11.

[0325] The empty package 3 is output to a disposal or collection device (not shown), such as a collection container or collection bag, or to a conveyor, chute, or shredder.

[0326] For example, in the illustrated example, the support platform 211 can be tilted to transfer the empty package 3 to a collection device, etc. Then, the package 3 can slide down and fall downwards.

[0327] Therefore, preferably, the intermediate plate 66, optionally provided in the illustrated example, is movable or pivotable (e.g., downward) to allow a path for the empty package 3. However, other structural solutions are also possible.

[0328] A particular advantage of the proposed device 1 and the proposed method is that, particularly preferably, the outer packaging 4 is opened so that it remains a single piece, i.e., not divided into multiple parts. This is advantageous and desirable for the transport, disposal, crushing, or further processing of the empty packaging 3 or the outer packaging 4.

[0329] Preferably, the empty packaging pallet 5A or the empty blister pack 5A is transferred from the separating device 60 to the conveyor 65, specifically the conveyor 65 being a conveyor belt, chute, etc., so that it can be transported away in a desired manner and, for example, transferred to a waste container or waste bag.

[0330] Preferably, the empty packaging pallet 5A or empty blister pack 5A is removed or pushed away from the receiving area 61, to fall, for example, into or onto the conveyor 65. For this purpose, preferably, the device 1 or the separating device 60 or its adjusting device 67 has at least one pusher, particularly a pivotable push arm 68, to push the empty packaging pallet 5A or empty blister pack 5A toward, for example, the conveyor 65, especially in the direction of the conveyor 10. However, other structural solutions are also possible.

[0331] Once the packaging pallet 5A or blister pack 5A has been removed from the workpiece 2 by the separating device 60 or the separating robot 63 (especially pivoted away), the exposed workpiece 2 is first picked up and transported away from the receiving area 61 by the delivery device 80. Subsequently, the separating device 60 or the separating robot 63 can place the empty packaging pallet 5A or empty blister pack 5A back onto the receiving area 61 so that it can be subsequently transferred back to the conveyor 65 by displacement. However, depending on the structural configuration, the separating device 60 can alternatively perform the transfer directly to the conveyor 65 in this case.

[0332] Particularly preferably, the proposed device 1 and method further have the following features: if an error occurs during the opening of the package 3 and / or the removal of the workpiece 2, the workpiece 2, together with, in particular, the entire package 3 or the outer package 4, is returned to the conveying device 10 or the transport carrier 11, especially to the same transport carrier 11 that carried the package 3 containing the workpiece 2. Preferably, this return process is carried out in a spatially separated manner, particularly simultaneously with or alongside the opening path of the package 3 and / or simultaneously with or alongside the removal path of the workpiece 2.

[0333] Particularly preferred, in accordance with Figure 10 In the schematic top view, the opening of package 3, or at least on the opposite narrow side, occurs at least generally on the right side, particularly preferably in the vicinity of the area where package 3 with workpiece 2 is supplied by conveyor 10, and / or in a straight line generally transverse to the conveying direction 10 (i.e., in the Y direction).

[0334] Then, preferably, the opening of the package 3 and / or the removal of the workpiece 2 and its transfer to the conveying device 10 are carried out with a slight offset in the conveying direction X, according to... Figure 10 As shown, it is performed to its left side or at least roughly in the center of device 1, and / or similarly along the removal path in the Y direction.

[0335] In short, according to Figure 10 In the top view, during the opening of package 3 and its subsequent removal and return, workpiece 2 moves at least roughly in a large U-shape.

[0336] Instead, package 3 is only roughly removed from conveyor 10 and remains largely in the area of ​​device 1 spaced apart from conveyor 10 for subsequent transfer to collection device.

[0337] Lateral movement of the device 1 away from the rear region of the conveying device 10, particularly in the X direction, is preferably accomplished by the transfer device 210, which is specifically formed by a movable or displaceable receiving platform 211. However, as mentioned above, other structural solutions are also possible.

[0338] Particularly preferred, in accordance with Figure 10 In the top view, the return of the error occurs offset relative to the aforementioned U-shaped motion flow, and / or particularly occurs next to the delivery device 80 and the separation device 60, or next to the removal and transfer process of workpiece 2 or next to the removal path.

[0339] Particularly preferably, in the event of an error, the transfer device 210 or the receiving table 211 can transfer the package 3 containing the workpiece 2 to the return device 90 of the equipment 1 by continuing to move or by lateral movement in the X direction.

[0340] In the illustrated example, preferably, the return device 90 has a chute or conveyor 91 and / or a pushing device 92 so as to transfer the defective package 3 together with the corresponding workpiece 2 intact to the desired transport carrier 11.

[0341] In the event of an opening error, the transfer device 210 or the receiving table 211 moves or transports the defective package 3 containing the workpiece 2 to the return device 90 or the conveying trough 91, and causes the defective package 3 to slide into or fall into the conveying trough 91 together with the workpiece 2.

[0342] With the aid of the return device 90, the conveyor 91, or the pusher 92, the defective package 3, together with the workpiece 2, is then conveyed to the desired transport carrier 11, and in particular, can be directly output to or from there.

[0343] In the illustrated example, preferably, the conveying trough 91 is movable on the conveying device 10 or the transport carrier 11, and / or is provided with a hinged cover and / or a pushing device 92, so that the defective package 3 can be safely and intactly transferred to the transport carrier 11, and in particular, the defective package 3 can be allowed to slide into or fall into the transport carrier 11.

[0344] However, other structural solutions are also possible.

[0345] In the second embodiment, as previously described, preferably two packages 3 are opened simultaneously and two workpieces 2 are removed simultaneously, particularly for achieving high throughput. However, in principle, the packages 3 can also be opened one by one or sequentially, and / or the workpieces 2 can also be removed. Therefore, the description and explanation of the second embodiment also apply accordingly to this situation. For example, if we are referring to a plurality of packages 3, the device 1 or the corresponding apparatus can also be configured in a corresponding manner such that only a single package 3 is processed and opened accordingly.

[0346] Furthermore, when workpiece 2 is removed from its packaging or taken out of an opened package 3, package 3 can also be opened from the side simultaneously to increase throughput. This can be achieved either by opening two packages 3 at the same time or by opening them one by one.

[0347] The aforementioned uses of device 1, method sequence, and proposed applications, as well as one aspect, feature, and idea of ​​the two implementation methods, can also be implemented independently of each other or in any desired combination.
