Description
Technical Field
The present invention relates to an apparatus for processing an ophthalmic lens according to the preamble of claim 1.
Background
The processing of the ophthalmic lenses is performed in a plurality of separate processing devices, in particular the processing of the ophthalmic lenses and/or the spectacle lenses is performed in a plurality of separate processing devices. In particular, the processing may include: shaping, preferably machining; polishing; testing and/or measuring; marking; cleaning; and/or coating.
For connecting the processing devices, serial processing is performed using a conveyor system of a belt conveyor, which transports ophthalmic lenses and/or lens carriers loaded with ophthalmic lenses from one processing device to the next.
EP2822883B1 discloses an apparatus for independent processing of optical lenses in a plurality of separate processing devices, in particular for spectacles. Each processing device includes its own conveyor for conveying lenses and/or lens carriers to and from the processing device. A conveyor system with a first conveyor track T1 for conveying lenses and/or lens carriers from one processing device to the next and a second parallel conveyor track T2 for parallel conveying of lenses and/or lens carriers is used as conveyor. Furthermore, the transfer system comprises a transfer device arranged between the processing devices for receiving and temporarily storing the lenses and/or the lens carriers and for conveying the lenses and/or the lens carriers further to a conveyor track of the processing devices or to a second conveyor track T2 as required. The first transport track T1 is formed by a transport device and a transport device assigned to the processing device, each of which can be controlled and driven independently.
In the general device known from EP2822883B1, the first transport track T1 is constituted by a transfer device and a conveyor device assigned to the processing device, each of which comprises its own drive system and two conveyor belts. Furthermore, the second transport track of the generic device is assigned to a separate conveyor device with two conveyor belts.
Furthermore, the transport device of the generic device known from EP2822883B1 is composed of a plurality of individually driven parts.
The transport system of the generic device therefore has a very complex structure with a plurality of transport sections, a plurality of conveyor sections and thus a number of drives and/or drive systems.
Disclosure of Invention
The invention is based on the task of further simplifying the general equipment for processing ophthalmic lenses.
The above-mentioned task is solved by a device according to claim 1.
The apparatus according to the present solution comprises a plurality of individual processing devices for the independent processing of ophthalmic lenses, in particular for the independent processing of lenses of spectacles. The processing device is positioned on a continuous conveyor. The conveyor serves to guide ophthalmic lenses to and/or from the respective processing device, in particular to guide ophthalmic lenses on the lens carrier to and/or from the respective processing device.
Preferably, the continuous conveyor comprises two conveyor tracks, in particular to allow independent parallel processing of the ophthalmic lenses in separate processing devices. The first transport rail is used in particular for transporting ophthalmic lenses and/or lens carriers from one processing device to the next, and the second transport rail is used for parallel transport, in particular as a chasing rail on which ophthalmic lenses and/or lens carriers which are not required and/or cannot be fed to the processing device are additionally transported.
According to a first aspect of the invention, the conveyor comprises at least one continuous conveyor belt and at least one drive system.
Compared to the prior art, the device according to the present solution has a substantially simplified design, since the conveying means are now continuous with respect to the conveying direction and are not constituted by separate subunits. According to a first aspect of the invention, only one continuous conveyor is now provided for the two transport tracks, particularly preferably only one continuous conveyor belt. Concomitantly, a significantly reduced drive system is particularly required for operating the conveying device, particularly preferably only one drive system is required for operating the conveying device. This allows for a significant reduction in control and assembly costs.
A basic aspect of the invention, which can also be implemented independently, is that each processing device is directly adjacent to the first transport track T1, i.e. the first transport track T1 preferably extends directly through the processing device, instead of through the processing device as described in EP2822883B 1.
For the purposes of the present invention, the term "directly adjoining" is to be understood primarily as the first transport track T1 extending directly through the processing device and not through the processing device.
Preferably, the processing device is positioned directly on the first transport track T1, in particular substantially free of voids and/or distances. This makes maintenance work simpler and reduces complex assembly and/or equipment extensions to include further machining devices, since these now only have to be moved and directly connected to the conveyor and/or the transport track T1.
The term "directly adjoining" is therefore also to be understood as meaning that the processing device and the transport track T1 and/or the conveying device are directly adjoining one another, in particular at least substantially free of distances and/or gaps.
Alternatively, however, the processing device may also be spaced apart from the conveying device, in particular from the first transport track T1. This distance is preferably limited by the range of the respective handling means for loading and unloading the processing means.
In principle, all known lens carriers are suitable for the device of the present solution. The most common lens carriers comprise, in a manner known per se, two holding positions for holding up to two ophthalmic lenses, which is a convention in lens and/or ophthalmic lens production. The lens carrier serves to pre-position the ophthalmic lens, so that the processing device can be loaded particularly reliably. The ophthalmic lenses may also be individually removable from the lens carrier.
The distance between the pick-up locations for the ophthalmic lenses within the lens carrier is preferably the same as the distance between a pick-up location in the lens carrier and an adjacent pick-up location in the immediately adjacent lens carrier. This simplifies handling and/or positioning of the ophthalmic lens, in particular in the holding area of the processing device for loading and unloading the ophthalmic lens on the processing device.
A conveyor is required to transport ophthalmic lenses and/or lens carriers from one transport rail to another.
According to a particularly preferred aspect of the invention, which can also be implemented independently, each transfer device is designed as a pushing device which pushes ophthalmic lenses and/or lens carriers from one transport rail to another, in particular from one transport rail to another in a manner transverse to the conveying direction.
The ophthalmic lenses and/or lens carriers are transported from one transport rail to the other transport rail by means of a pusher, preferably from one transport rail to the other transport rail transversely to the transport direction, and particularly preferably from one transport rail to the other transport rail along the shortest path, i.e. at approximately right angles to the transport direction. However, the transverse transport can also take place at other angles with respect to the transport direction. In particular, the transport can be carried out obliquely with respect to the transport direction, preferably both in the transport direction and counter to the transport direction. The lens carriers are transported laterally by the pusher, in particular such that the lens carriers are transported from one transport rail to the other in a particularly reliable and as possible manner.
This design of the transmission device as a push device facilitates a significantly simplified and cost-effective construction by eliminating the transmission device known from EP2822883B1, which consists of a plurality of subunits and a drive system. In particular, a transverse transport and/or a travel-free transverse transport can be achieved during the operation of the conveyor belt. In other words, simpler and faster transmission can be achieved.
Preferably, the conveyor belt is provided with a particularly smooth surface, in particular without shoulders and unevenness, particularly preferably a connecting belt with a smooth surface. One advantage of a conveyor belt in the form of a continuous connecting belt is that, unlike in EP2822883B1, the lens carriers do not have to travel precisely on a transport track, but can be transported in different sizes using the apparatus according to the present solution. For example, lens carriers of different widths can be transported on a conveyor belt, provided that the width of the lens carrier does not exceed the corresponding transport track.
After the ophthalmic lenses have been processed at the processing device, the ophthalmic lenses may be transported on the first conveyor track to a pusher device downstream of the respective processing device at a pick-up location of the respective lens carrier. If it is now desired not to process ophthalmic lenses at the nearest processing device but at a further processing device, the lens carrier carrying the processed ophthalmic lenses is pushed from the first transport rail to the second transport rail by the pushing device transversely to the transport direction, so that the nearest processing device in the transport direction can be tracked on the second transport rail. The ophthalmic lens and/or the lens carrier to be processed, which is now located on the second transport rail, can be pushed from the second transport rail onto the first transport rail by means of the pushing device transversely to the transport direction after reaching the pushing device located in front of the processing device at the place where the next processing is to be performed.
In the case of a necessary and/or desired stopping of the lens carriers in a holding area in front of the processing device or in front of the pushing device, for example in the case of a large number of lens carriers, in particular in order to avoid collisions with the lens carriers, stopping means are provided on the transport rail, in particular to enable the conveying device to continue to run continuously.
Advantageous further developments are the subject matter of the dependent claims.
According to a particularly preferred aspect of the invention, which can also be implemented independently, each pushing device comprises a fork which can be moved in particular transversely to the conveying device. This is particularly helpful in carrying the lens carrier from one transport track to another as required. Preferably, the fork is designed and/or the opening of the fork is preferably located opposite the conveying direction, so that the lens carrier can pass the fork and/or under the fork when the conveyor belt is running, in particular because the lens carrier is not clamped between the retaining arms of the fork (see below). The fork-like part of the pushing device ensures that only one continuous conveying device is needed and that no separate subunit of the conveying device for transverse conveyance is needed.
Another aspect of the invention, which can also be implemented independently, is that the pushing device comprises a fork with an adjustable height. An advantage of this further embodiment is that the lens carrier can leave the pushing device faster due to the rapid rise of the fork during the running of the conveyor belt. This helps, inter alia, to prevent stacking of lens carriers and/or to achieve higher throughput.
In the case of a pile of lens carriers, a stop device is provided to stop the lens carrier, in particular in front of the pushing device, i.e. in front of the fork occupied by the lens carrier or on the opposite transport rail to which the lens carrier is to be pushed by the fork. The device is preferably positioned on the conveyor such that the following lens carrier does not accumulate behind and/or collide with another lens carrier when the conveyor is running and/or is not occupied before lateral transport by the pusher occurs in a waiting position to which the lens carrier is to be pushed by the fork of the pusher.
Particularly preferably, the pushing device comprises a linear drive for laterally transporting the fork, which in particular pushes the ophthalmic lens and/or the lens carrier from one transport rail to the other. In contrast to the device known from EP2822883B1, the transmission device thereof is formed by a plurality of sub-units, each having its own drive and/or motor, which results in a significant reduction in control and assembly costs.
Preferably, the fork of the pushing device is movable in two directions transverse to the conveying direction. This allows a significant reduction in material and assembly costs, since only a single drive pushing device is required to push the ophthalmic lens and/or lens carrier from one transport rail to another, without the need for a transfer device made up of a plurality of individually driven subunits.
Particularly preferably, the pushing device is arranged on the conveying device, preferably between two processing devices and/or before each processing device and/or after each processing device. This has the advantage that the arrangement of the pushing device is independent of the position and/or location of the processing device.
Alternatively or additionally, the pushing device can also be attached directly to the processing device, in particular on the side of each processing device that can be reached first with respect to the conveying direction of the lens carrier. This means that if the apparatus is modified, for example by adding additional processing means, it is no longer necessary to attach the pushing means to the conveying means, but the processing means can be pushed directly to the conveying means.
It is also conceivable to arrange a plurality of pushing devices, preferably two pushing devices, directly following one another on the conveying device or also on the processing device. This is mainly to achieve a higher throughput and a smooth and/or delay-free procedure. For example, if during a running conveyor belt a first lens carrier is to be pushed from the second conveyor track to the first conveyor track, so that the corresponding ophthalmic lens of the first lens carrier can be processed at a subsequent processing device in relation to the conveying direction, whereas the second lens carrier is located on the first conveyor track in a region in front of the pushing device in relation to the conveying direction, it is necessary to first push the second lens carrier to the second conveyor track, so that the region in front of the processing device on the first conveyor track is free for processing the first lens carrier, the second lens carrier can be pushed from the first conveyor track onto the second conveyor track by means of the first pushing device, whereas the subsequent pushing device in relation to the conveying direction can push the first lens carrier to be processed from the first conveyor track onto the second conveyor track.
It is of course also conceivable for two lens carriers transported one behind the other on one transport track to enter the fork-shaped parts of two pushing devices arranged one behind the other and to be pushed in parallel onto the other transport track.
If the number of lens carriers is small, it is also possible to push the lens carriers from one transport track to the other transport track, respectively, using a first or a second pushing device with respect to the transport direction, depending on the desired position of the lens carriers on the transport device.
A possible embodiment of the apparatus of the present solution is that the conveyor comprises a conveyor belt with two transport tracks and a common drive system. This is associated with low assembly costs and particularly simple transverse transport, since the two transport tracks extend on a common conveyor belt and therefore the fork of the pusher only has to be displaced transversely to the transport direction on the running conveyor belt.
In a particularly preferred embodiment, the conveyor means comprises two separate conveyor belts, each in the form of a transport track, and preferably a common drive system. Preferably, a space is provided between the two separate conveyor belts, forming an intermediate space. Various measuring devices such as stops and sensors can be accommodated in this intermediate space, which reduces the space and/or area requirements of the apparatus due to the inward displacement between the two conveyor belts. Thus, more space is available for the processing apparatus as well as for the operator. Furthermore, this ensures a more advantageous connection of the processing device to the conveying device.
It is however also conceivable for the conveying device to comprise two conveyor belts, each in the form of a conveyor track, wherein each conveyor belt has a drive system or particularly preferably a common drive system, in particular with an epicyclic gear unit known per se. This design allows independent operation of the conveyor belt and/or the transport track, in particular at different speeds. This may be advantageous, for example, if multiple lens carriers are to be transported past multiple processing devices on the chase, to avoid stacking of the lens carriers and/or to transport the lens carriers loaded with ophthalmic lenses faster to more distant processing devices and/or to achieve higher throughput.
A particularly preferred embodiment of the apparatus of the present embodiment with two spaced conveyor belts provides that each pusher is assigned an intermediate plate arranged between the conveyor belts. This helps bridge the distance between the conveyor belts so that cross-conveying of ophthalmic lenses and/or lens carriers from one conveyor belt to another conveyor belt can be performed particularly reliably.
The intermediate plate can also be used for temporary storage of the lens carrier, i.e. as a waiting position, for example, to achieve higher throughput. For example, if a first lens carrier is to be tracked on a conveyor track so that a subsequent second lens carrier can arrive first to a subsequent processing device, for example, if there is room for processing the corresponding ophthalmic lens of the second lens carrier at this time, the first lens carrier can be pushed onto the intermediate plate by the fork of the pushing device and temporarily stored on the intermediate plate so that the second lens carrier can track over the first lens carrier.
Conveniently, the width of the intermediate plate preferably corresponds at least to the width of the lens carrier.
Another aspect of the invention, which can also be implemented independently, is that the width of the conveyor and/or the conveyor belt is determined by the width of the lens carrier.
Preferably, the width of the transport track corresponds at least to the width of the lens carrier. It can be seen that the width of the conveyor preferably corresponds at least to the number of transport tracks multiplied by the width of the lens carrier.
In the above-explained embodiment with two conveyor tracks on the conveyor belt, the width of the conveyor belt and the conveyor is at least twice the width of the lens carrier.
In a particularly preferred embodiment of the conveyor with two spaced conveyor belts and/or conveyor tracks, the width of the conveyor is at least twice the width of the lens carrier plus the width of the distance between the conveyor belts, and the width of each conveyor belt is at least equal to the width of the lens carrier.
In general, in the case of a plurality of conveyor belts, i.e. in the case of at least two conveyor belts, the width of the conveyor device corresponds at least to the product of the number of conveyor belts and the width of the lens carrier, in particular plus the respective distance between the conveyor belts.
Preferably, the device according to the present solution comprises a guiding rod, in particular at the edge of the conveyor belt, parallel to the conveying direction, in particular for guiding the ophthalmic lens and/or the lens carrier. This causes the lens carrier to be guided at least substantially in a straight line along a transport track on the conveyor belt and/or prevents the lens carrier from running at an angle and/or falling off the apparatus.
In the region of the pushing device, in the case of at least two spaced-apart conveyor belts, a recess is preferably provided in the guide bar, which recess in particular corresponds to the size of the lens carrier. This design allows for simple, rapid lateral transport without the need to lift the lens carrier from one conveyor to another. The lens carrier is guided by the side elements of the fork through and/or into the fork parallel to the conveying direction.
According to another aspect of the invention, the apparatus according to the present solution is configured such that the circulation of the ophthalmic lens and/or the lens carrier can be performed in a loop. This allows the ophthalmic lens and/or lens carrier to be accessed repeatedly and/or in any order to the processing means and the order of processing, utilization of the processing means and the processing sequence can be changed and/or optimized. In this way, lens carriers can be prevented from piling up, in particular before or at the processing device.
A possible embodiment of the cycle is that the conveying means of the device according to the present solution are expanded or connected and/or can be expanded or connected to form the device. In particular, this allows for circulation or recycling of the ophthalmic lens and/or lens carrier. Such a device may consist of one or more conveyor belts with one or two transport tracks, in particular in the form of a ring or oval. In the case of multiple conveyor belts, the conveyor belts may be spaced apart from one another and/or directly adjacent to one another.
The transport device of such a device is particularly preferably driven by a common drive system, but may also comprise a plurality of drive systems. Preferably, the processing means are arranged along an at least substantially straight long line of the preferably elliptical factory system, but may also be arranged at any other desired location, such as on the inner side or the short side of the factory system.
According to another aspect of the invention, a plurality of conveyor devices may also form a factory system.
A preferred embodiment of such a factory system of the system according to the present solution is a U-shaped or endless arrangement with two conveyor means facing each other, wherein preferably a conveyor belt with one or two conveyor tracks is provided, or two spaced conveyor belts in the form of one conveyor track each.
Along the conveyor facing each other, a plurality of processing devices are preferably arranged in a row in a manner known per se, which processing devices are preferably directly adjacent to the first transport rail.
Preferably, a connecting element is provided for circulation of the ophthalmic lens and/or the lens carrier, for example a curved portion or a lateral connecting portion, which connects the conveying means opposite to each other, in particular around a corner and/or a curved portion. The curved delivery ensures that the alignment of the ophthalmic lens and/or lens carrier is maintained constant with respect to the respective delivery direction.
According to a particularly preferred aspect of the above-described embodiment of the apparatus of the present aspect, each of the two conveying means facing each other comprises two conveyor belts connected to each other via a pushing means, each conveyor belt being in the form of a transport track. It is particularly preferred that the second transport rails of the conveyor are connected to each other via connecting elements, such as bends and/or transverse connections, respectively, to ensure endless transport. The function of the pushing device is to transfer ophthalmic lenses and/or lens carriers from one transport rail to another transport rail or to push all ophthalmic lenses and/or lens carriers to be transferred from one transfer device to another to the second transport rail.
According to a further aspect of the invention, the device according to the present solution comprises more than two transport rails, particularly preferably a third transport rail for parallel transport, in particular for fold-back transport of ophthalmic lenses and/or lens carriers.
Preferably, the first and second transport tracks are opposite to the transport direction of the third transport track.
A preferred embodiment of the apparatus of the present solution is that the first and second transport rails extend in one direction and the third transport rail extends in the opposite transport direction in parallel with the first and second transport rails. The third transport rail is used to fold back the ophthalmic lens and/or lens carrier. It is therefore preferred that a plurality of processing devices are arranged along the first transport track, while the third transport track is used only for return transport.
According to a particularly preferred aspect of the above-described embodiment of the invention, only one common drive system is provided for all three transport tracks on one conveyor belt, each conveyor belt being on a common conveyor device. The reversal of the conveying direction and/or the driving of the third transport track is effected, for example, by means of planetary gears in a manner known per se.
Furthermore, pushing means for changing the transport rails are provided, preferably at right angles to the transport direction, in particular between the processing means, which pushing means can push the ophthalmic lenses and/or lens carriers over two or three transport rails. The pushing device extending on the three transport rails allows circulating and/or transporting ophthalmic lenses and/or lens carriers on the three-rail transport device. In particular, the conveyed ophthalmic lens or lens carrier may be repeatedly conveyed onto and/or out of the processing device.
According to a particularly preferred aspect of embodiments of the present disclosure, the pushing device, which is preferably arranged between the processing devices, may be used to initiate a return conveyance after each processing device, in particular via the third conveying track, instead of only at the end of the conveying device. This makes it possible to avoid blocking of the lens carriers and in particular to achieve a higher throughput, since the lens carriers can be circulated over a shorter distance without having to be transported back over the entire distance of the third transport rail before being pushed again onto the first transport rail adjoining the processing device via the pushing device.
The three-track design of the conveyor belt and/or the conveyor device described above can also be integrated into more complex processing equipment, such as the processing equipment known from EP2822883B 1.
According to a particularly preferred aspect of such an apparatus of the invention, the three-rail conveyor may be connected to at least one further, preferably opposite conveyor. For example, the connection may be made via the connection elements described above. It is here conceivable to make the connection on both sides of the conveyor to form a loop-shaped or U-shaped arrangement, wherein one side of the conveyor belt is maintained open by omitting the connecting element, and thus the intermediate space between the two conveyor devices, which are preferably parallel, is still accessible to the operator.
The rows of two conveying means and/or processing means in the apparatus are preferably spaced apart such that the intermediate space forms a reach possibility for the operator. This is particularly easy for the operator to reach in the case of a U-shaped arrangement. In the case of a ring-shaped arrangement, the connecting element is designed such that it can be released and/or opened or folded as required in order to access the intermediate space. Alternatively or additionally, the connecting element may also be placed higher or lower and/or connected, for example, via a vertical conveyor or a downhill section, so as to ensure a preferably free access to the intermediate space.
The intermediate space may alternatively or additionally be used in a manner known per se for a container for an operating fluid of a processing device, such as a container for chips, polishing agent or coolant. However, these containers may also be arranged below the conveyor belt. In this way, the intermediate space can be used for other purposes or reduced in size if necessary, and thus the entire apparatus can be kept narrow to save space.
In a further embodiment of the apparatus of the present solution, the processing means are not arranged outside the ring-shaped and/or U-shaped system, but in the space between the two conveying means, and preferably such that the space between them remains as narrow as possible, but each processing means can still be easily and quickly reached by the operator. In addition to the significant space savings due to the elimination of outwardly projecting machining devices, another advantage of this alternative embodiment is the shorter path for the operator from one machining device to another.
It is particularly preferred that the three-track conveyor is combined with a double-track conveyor, the two transport tracks of which extend in the same direction, in particular the first and the second transport track. In this embodiment, a plurality of processing devices are arranged along each of the conveying devices, in particular along the first transport track, preferably in a row. The triple track conveyor with the return third transport track is preferably used as a fast wire, the task of which is to ensure a high throughput.
According to another aspect of the apparatus of the present embodiment, the third transportation rail and the above-mentioned connecting element may also be combined, if desired.
It is conceivable, for example, that the second transport rail is connected around the bend and/or the corner by known connecting elements to a third transport rail which extends in parallel with and in opposite direction to the second transport rail.
Another aspect of the invention, which can also be implemented independently, is the simplification and/or optimization of the automation of the entire conveying system of the device according to the present solution, compared to the general device known from EP2822883B 1.
In the apparatus known from EP2822883B1, the transport devices belonging to the first transport track and assigned to the processing devices are each individually controlled by the machine control system and do not form part of the transport control system, i.e. the transport system is not controlled centrally by one control system but by a plurality of control systems, i.e. by the central control system and the machine control system.
On the other hand, in the apparatus of the present embodiment with all the embodiments described above, a control system is provided, in particular a central control system, which controls the entire conveying system in the holding area in front of the respective processing device, i.e. the conveying device comprising the conveyor belt and/or the transport rail, the pushing device and the stopping device. The processing devices are independently controlled and/or separately controlled by a central control system, i.e. by their own machine control system, to effect independent processing. It is of course also possible that the stopping means are also controlled by the machine controller.
This shifting of automation to the central control system allows a considerable reduction in the complexity of the assembly, changeover and maintenance work of the apparatus of the present solution, in particular since the processing device with its own machine controller only has to be connected to the central controlled conveyor device, not to any additional separate conveyor device assigned to the processing device. This makes it easier to extend the apparatus of the present solution to include additional processing means and/or to form the apparatus.
Each of the above and subsequent aspects and features of the invention may be combined with each other in any desired manner, but may also be implemented independently of each other.

Detailed Description
Fig. 1 shows a schematic view of a preferred embodiment of an apparatus 1 for processing a lens 2 according to the present solution, in particular the lens 2 is an ophthalmic lens 2.
The ophthalmic lens 2 is preferably an ophthalmic lens, i.e. a lens for spectacles and/or ophthalmic lenses. Alternatively, however, the ophthalmic lens may also be another lens, such as a contact lens.
The ophthalmic lens 2 is preferably made of plastic, but may be made of glass or other materials if desired.
The apparatus 1 according to the present embodiment preferably comprises a plurality of individual processing means 3, in particular for the individual processing of the ophthalmic lenses 2.
As known from EP2822883B1, the apparatus 1 may comprise a plurality of individual processing devices 3, such as for blocking, shaping, in particular machining, polishing, testing and/or measuring, marking, and cleaning and coating the ophthalmic lens 2.
It is further known from EP2822883B1 that not only different types of processing devices 3 but also a plurality of apparatuses of the same type can be integrated into the apparatus 1 for the same processing.
As shown in fig. 1, the apparatus 1 of the present solution comprises a conveyor 4, which conveyor 4 is used for transporting ophthalmic lenses 2 and/or lens carriers 5, in particular for transporting ophthalmic lenses 2 and/or lens carriers 5 from one processing device 3 to another. The conveyor 4 comprises the following tasks: the ophthalmic lens 2 and/or the lens carrier 5 are fed into the respective processing device 3, the ophthalmic lens 2 and/or the lens carrier 5 are transported from one processing device 3 to another processing device 3 after the processing is completed, and/or the ophthalmic lens 2 and/or the lens carrier 5 are guided out of the processing device 3.
As is known from EP2822883B1, the ophthalmic lens 2 and/or the lens carrier 5 can be transported onto the transport device 4, for example, by a pick-up station (not shown) transporting the ophthalmic lens 2 and/or the lens carrier 5 onto the transport device 4. The lens 2 and/or the lens carrier 5 may be removed from the conveyor 4 by a transfer station (not shown).
The conveyor 4 comprises at least one conveyor belt 6, in particular a continuous conveyor belt 6, preferably two continuous conveyor belts 6, 6', as shown in fig. 1 and 2.
Furthermore, the conveyor device 4 preferably comprises two transport tracks T1, T2, in particular wherein the conveyor belts 6, 6' are each formed by at least one transport track T1, T2.
In the illustrated example, the conveyor belts 6, 6' correspond to respective transport tracks T1, T2 (fig. 1 and 2). In particular, the conveyor belts 6, 6' form respective transport tracks T1 and T2.
In an alternative embodiment (not shown), the at least one conveyor belt 6, 6' comprises a plurality of transport tracks, in particular two transport tracks T1, T2.
The conveying direction of the conveyor belts 6, 6' is indicated by arrows F1 and F2 in fig. 1 and 2, respectively. The conveying direction of the conveyor tracks T1, T2 is thus preferably aligned with the conveying direction of the conveyor belts 6, 6'.
Preferably, in the illustrated embodiment of the apparatus 1 according to the present solution, the second conveyor belt 6' and the transport track T2 are conveyed in the same direction as the first conveyor belt 6 or the first transport track T1.
However, other constructive solutions are also possible here.
The first transport track T1 is preferably directly adjacent to the processing device 3. In particular, the first transport track T1 serves to transport lenses 2 or lens carriers 5 from one processing device 3 to the next processing device 3 or to connect the processing devices 3 to each other.
According to the preceding definition of the term "directly adjoining", the processing device 3 and the transport track T1 and/or the conveying device 4 are preferably directly adjoining each other, in particular at least substantially free of distance and/or play.
The processing device 3 can thus be positioned in particular directly on the conveyor 4 and/or the transport track T1.
A particular advantage of the device 1 according to the present embodiment is therefore that, depending on the requirements, the device 1 can be extended very easily by means of the additional processing devices 3, since these only have to be pushed onto the conveyor 4 and/or the transport track T1.
The at least substantially parallel second transport track T2 is used for transporting the respective ophthalmic lens 2 or lens carrier 5, in particular for transporting and/or otherwise transporting the respective ophthalmic lens 2 or lens carrier 5 in parallel. In particular, the transport track T2 serves as a transit track on which the ophthalmic lenses 2 and/or the lens carriers 5 which do not need to be fed into the processing device 3 are transported in addition.
Preferably, a distance is provided between the particularly individual conveyor belts 6, 6 'such that an intermediate space is formed between the conveyor belts 6, 6'. This has the advantage that various components can be accommodated, in particular measuring devices such as the stop device 31 and/or the sensor 32.
Fig. 1 shows a plurality of stop means 31 in the form of spacers. These stop means stop the lens carrier 5 as required, in particular when the conveyor belts 6, 6' are running. The lens carrier 5 is stopped, in particular in order to position the lens carrier 5 alone at a corresponding position on the transport rail 4, for example on the transport rail T1 in the region of the processing device 3, in particular for loading and unloading the ophthalmic lens 2 on the processing device 3, and on both transport rails T1 and T2 in front of the pushing device 10. The stop means 31 are preferably located in front of the respective pushing device 10 with respect to the conveying direction F1, F2, preferably at a distance from the pushing device 10 and/or from each other, in particular at least one length of the lens carrier 5. Furthermore, the stop means 31 are provided in the holding region of the processing device 3, which processing devices 3 are in particular spaced apart from one another, so that the loading and unloading of the lens carrier 5, in particular the loading and unloading of the ophthalmic lens 2 onto the lens carrier 5, can be carried out particularly reliably.
The device 1 according to the present solution preferably comprises a sensor 32, such as: an optical scanner, in particular for detecting the presence and position of the lens 2 and/or the lens carrier 5, and/or a bar code reader, in particular for identifying the ophthalmic lens 2 and/or the lens carrier 5.
In the example shown, the conveyor belts 6, 6', which in particular form the transport tracks T1, T2 respectively, are driven by a common drive system 7 (fig. 2), preferably such that the two conveyor belts 6, 6' and/or the transport tracks T1, T2 rotate in the same direction, in particular at the same speed. In a particularly preferred embodiment, this is achieved by a drive shaft connecting the two conveyor belts 6, 6' in a manner known per se.
A further variant of the conveyor 4 of the device 1 according to the invention provides that the two conveyor belts 6, 6 'of the conveyor 4 are driven by two separate drive systems 7, 7' or preferably by a common drive system 7 with planetary gears. This enables in particular the circulation speed of the conveyor belts 6, 6' and/or the transport tracks T1, T2 to be varied. For example, it is conceivable to select a higher speed for the conveyor belt 6' and the transport track T2 than for the conveyor belt 6 and/or the transport track T1, in order to avoid stacking of the lens carriers 5 and/or in order to achieve a higher throughput when there are a large number of lens carriers 5. In such an embodiment, opposite conveying directions F1 and F2 are also conceivable.
In another embodiment, the conveying device 4 of the apparatus 1 according to the present embodiment may further include: (only) one conveyor belt 6, which is divided into two separate areas, namely two transport tracks T1 and T2; and a drive system 7.
Preferably, the conveying means 4 of the device 1 according to the present solution comprise a guiding rod 8, in particular arranged at the edge of the conveyor belt 6, 6'. It is particularly preferred that each conveyor belt 6, 6' is delimited by two guide rods 8.
The guiding rod 8 enables the lens 2 and/or the lens carrier 5 to be guided along the transport tracks T1, T2, in particular parallel to the transport directions F1 and F2, in particular at least substantially straight.
As can also be seen from fig. 1, the apparatus 1 according to the present solution comprises pushing means 10, which are preferably arranged between the processing means 3. Particularly preferably, the pushing device 10 is arranged between all processing devices 3 that are each adjacent. However, the following embodiments are also possible: the pushing device 10 is not arranged between all the processing devices 3, but only between some of them. Alternatively, the pushing device 10 can also be assigned to the processing device 3, in particular directly or indirectly adjoining the processing device.
In the example illustrated, the processing devices 3 are preferably arranged one after the other, in particular in a row, particularly preferably on a common side of the conveyor device 4 and/or the conveyor belt 6, 6', with respect to the conveying direction F1, F2.
The pushing device 10 is preferably used for transporting the lenses 2 and/or the lens carriers 5 from one transport track T1, T2 to another transport track and/or for transporting the lenses 2 and/or the lens carriers 5 from one conveyor belt 6, 6' to another, in particular as required, in particular transversely to the conveying direction F1, F2.
The transverse transport can take place in two directions R1, R2 transverse to the transport directions F1, F2. In the example shown, lateral transport may take place in the lateral direction R1 from the first transport track T1 and/or the first conveyor belt 6 to the second transport track T2 and/or the second conveyor belt 6', and vice versa, and lateral transport may take place in the direction R2 from the second transport track T2 and/or the second conveyor belt 6' to the first transport track T1 and/or the first conveyor belt 6.
For simplicity, the transverse directions R1, R2 in fig. 1 are perpendicular and/or at right angles to the conveying directions F1, F2. However, as mentioned above, the transverse transport may also take place at any other angle, in particular diagonally with respect to the transport directions F1, F2.
Furthermore, the pushing device 10 is designed to receive and temporarily store the ophthalmic lens 2 and/or the lens carrier 5 as required.
Preferably, the apparatus 1 according to the present solution comprises an intermediate plate 9, in particular in the region between the conveyor belts 6, 6' of the pushing device 10. The intermediate plate 9 serves in particular to bridge the distance between the conveyor belts 6, 6', in particular during the lateral transport of the ophthalmic lens 2 and/or the lens carrier 5 from one conveyor belt 6, 6' to the other by the pushing device 10.
Furthermore, in the region of the pushing device 10, in particular in the region of the intermediate plate 9, recesses and/or openings (see fig. 1, 3, 5 and 6) of the guide rod 8 are preferably provided, in particular to achieve a stroke-free lateral transport of the lens 2 and/or the lens carrier 5.
It is particularly preferred that the intermediate plate 9 is higher than the conveyor belts 6, 6 'themselves, and/or that the intermediate plate comprises inclined surfaces 9a, 9b on the edges facing the conveyor belts 6, 6', as shown in fig. 3. The bevel serves in particular for the upward transport of the lens carrier 5 onto the intermediate plate 9, preferably without lifting the lens carrier 5. The higher level of the intermediate plate 9 relative to the conveyor belts 6, 6 'again serves in particular to ensure that the lens carriers 5 do not get caught on the edges of the respective conveyor belt when being transported from the intermediate plate 9 onto the conveyor belts 6, 6' and/or the transport tracks T1, T2.
The transport or transverse transport of the ophthalmic lenses 2 and/or the lens carriers 5 by the pushing device 10 can be effected on the one hand from one conveyor belt 6, 6' to the other, in particular independently of the number of transport tracks on the conveyor belt. The lateral displacement can take place either between two spaced-apart conveyor belts 6, 6', which are connected to one another in particular by means of an intermediate plate 9, or between two conveyor belts 6, 6', which are directly adjacent to one another and/or are not spaced apart from one another.
Alternatively, the lateral transport of the ophthalmic lenses 2 and/or the lens carriers 5 by the pushing device 10 can also take place between a plurality of transport tracks T1, T2 on a common conveyor belt 6, 6'.
As shown in fig. 3, the pushing device 10 preferably comprises a fork 11, which in particular has two side elements 11a, 11b. In the illustrated example, the side elements 11a, 11b are connected to the holding surface 12, preferably in a single piece to the holding surface 12.
In the example shown, the pushing device 10 preferably comprises a vertical stop cylinder 13, in particular recessed into the holding surface 12. Particularly preferably, the stop cylinder 13 is designed as a pneumatic cylinder.
The stop cylinder 13 is preferably arranged to stop the lens carrier 5, in particular to stop the lens carrier 5 when the conveyor belt 6, 6' is running. As can be seen in particular from fig. 4, in the example illustrated, the stop cylinder 13 comprises an expandable piston 13a. If the piston 13a extends vertically downwards towards the conveyor belt 6, 6', the lens carrier 5 is stopped by the piston 13a and/or becomes rested against the piston 13a when the conveyor belt 6, 6' is running. When the piston 13a is in the retracted state, the lens carrier 5 can continue to run on the conveyor 4 and/or the conveyor belt 6, 6'.
As can be seen in addition from fig. 3, the fork 11 and/or the detaining surface 12 of the fork 11 are connected in particular via a fastening bracket 14 to a drive 15, which is preferably in the form of a carriage.
In particular, the driver 15 serves to drive the fork 11 so as to transport the lens carrier 5 laterally from one transport track T1, T2 to the other.
Preferably, the drive 15 is arranged to be linearly movable, in particular on the transfer cylinder 17.
The transfer cylinder 17 is preferably designed as a linear drive, in particular as a pneumatic cylinder.
In the example shown, the transfer cylinder 17 is mounted on a carrier 18. Preferably, a guide or rail 19, preferably designed as a linear guide, is attached and/or mounted on one longitudinal face of the carrier 18, in particular the guide or rail 19 is attached and/or mounted on the bottom face 18a of the carrier 18.
The fork 11 can be moved and/or positioned along the guide and/or rail 19, in particular linearly along the guide and/or rail 19, in particular by means of a slide 16 guided so as to be displaceable on the guide and/or rail 19.
In the example shown, the fork 11 is transported laterally, in particular via a linear drive of the transfer cylinder 17. The displacement and/or movement of the fork 11 and/or the slide 16 along the guide and/or the rail 19 makes the lateral transport of the fork 11 and/or the lens frame 5 particularly reliable or targeted, in particular the displacement or movement is linear. The two linear guide elements, namely the transfer cylinder 17 on the one hand and the guide and/or rail 19 on the other hand, ensure a particularly stable transverse transport.
According to another aspect of the invention, which can also be implemented independently, the following procedure can be carried out with the pushing device 10 in combination with the conveying device 4 of the apparatus 1 according to the present solution:
once the lens carrier 5 moves into the fork 11, the lens carrier 5 is stopped by the lowered piston 13a of the stop cylinder 13. For the lateral transport of the lens carriers 5 from one transport track T1, T2 to the other transport track and/or from one conveyor belt 6, 6 'to the other conveyor belt, the forks 11 are transported from one transport track T1, T2 to the other transport track and/or from one conveyor belt 6, 6' to the other conveyor belt by means of the transfer cylinders 17 and in particular by means of supporting linear guides along the guides and/or tracks 19 via the intermediate plate 9, the lens carriers 5 being carried along between the side elements 11a, 11b of the forks 11. When the lens carrier 5 is to be additionally transported on the transport tracks T1, T2 along the transport directions F1, F2, the piston 13a of the stop cylinder 13 is moved upwards so that the lens carrier 5 can pass the fork 11 on the moving conveyor 6, 6'. This is made possible in particular by the fact that no lateral clamping forces act on the lens carrier 5 from the side elements 11a, 11 b.
Alternatively, the lens carrier 5 may also pass directly through the fork 11 when the conveyor belt 6, 6' is running, i.e. there is no need to transport the lens carrier 5 laterally from one transport track T1, T2 to the other. This can be provided, for example, if the lens carriers 5 conveyed on the second conveyor track T2 are not processed at the processing device 3 nearest to the conveying direction F1, F2, but only on the subsequent processing device 3.
Fig. 5 and 6 show another embodiment of the pushing device 20 of the apparatus 1 according to the present solution.
The pushing device 20 preferably comprises a fork 21, which in particular has two side elements 21a, 21b. In the illustrative example, the side elements 21a, 21b are preferably connected to the (upper) holding surface 24 in a single piece. In the illustrated example, the pushing device 20 comprises a vertical lifting cylinder 23, in particular a pneumatic cylinder, which is placed in an (upper) holding surface 24 and whose lower end is preferably fastened to the lower holding surface 22.
According to a particularly preferred aspect of the invention, which can also be implemented independently, the fork 21 of the pushing device 20 can be height-adjusted, in particular along arrow H.
Preferably, the lifting cylinder 23 is adjustable and/or displaceable in height, in particular by means of a piston 23a, in particular along arrow H. Vertical displacement of the lifting cylinder 23 along arrow H causes the fork 21 to be displaced in height, in particular via the upper holding surface 24.
In the illustrated embodiment, the fork 21 is in a raised state. In this state, the lens carrier 5 can pass under the fork 21 while the conveyor 6, 6' is running.
As can be seen from fig. 6, a stop element, in particular a substantially vertical holding arm 25, is preferably used to stop the lens carrier 5 on the conveyor belt 6, 6', in particular circulating.
If the lifting cylinders 23 are in a non-raised state on the lower holding surface 22, the lens carrier 5 is stopped by the holding arms 25 when the conveyor belt 6, 6 'is running, and the lens carrier 5 can continue to run with the conveyor 4 and/or the conveyor belt 6, 6' when the lifting cylinders 23 connected to the fork 21 by the upper holding surface 24 are raised along the piston 23 a.
In the case of the pushing device 20, the lateral transport of the ophthalmic lens 2 and/or the lens carrier 5 takes place in the same way as in the case of the pushing device 10 (see above).
A particular advantage of the pushing device 20 and/or in particular the preferably height-adjustable fork 21 of the pushing device 20 is that the lens carrier 5 can leave the pushing device 20 relatively quickly and/or be carried with the conveyor belt 6, 6' by a rapid elevation of the fork 21. This may prevent clogging of the lens carrier 5 and/or achieve a higher throughput. For the lateral transport of the ophthalmic lenses 2 and/or lens carriers 5 from one transport track T1, T2 to the other transport track, the fork 21 with the lens carrier 5 remains on the conveyor belts 6, 6' or the intermediate plate 9 at all times.
The prongs 11, 21 of the pushing device 10, 20 are preferably wider than the lens carrier 5, in particular in order to ensure that the lens carrier 5 is substantially free of resistance when entering and/or passing the prongs 11, 21. The width of the fork 11, 21 is advantageously selected in particular such that when the lens carrier 5 is carried along the fork 11, 21 and/or transported laterally by the fork, it can be pushed from one transport track T1, T2 to the other transport track and/or from one conveyor belt 6, 6' to the other with particular reliability, in particular with little play.
Fig. 7 shows a schematic top view of a preferred embodiment of a lens carrier 5 for housing at least one ophthalmic lens 2, in particular two in the example shown.
Preferably, two ophthalmic lenses 2 and/or pairs of lenses to be processed are accommodated by a lens carrier 5, as is common in lens or ophthalmic lens production.
The lens carrier 5 preferably comprises two receiving locations 41, which are intended in particular for receiving the ophthalmic lens 2. In particular, the receiving position is designed such that a sliding of the ophthalmic lens 2, in particular a sliding of the ophthalmic lens 2 during transport and/or stopping of the lens carrier 5, can be avoided. In particular, this allows the spatial position of the ophthalmic lens 2 on the lens carrier 5 to be maintained particularly stable and thus loading and unloading can be carried out particularly reliably, in particular in the holding area of the processing device 3.
Preferably, in the illustrated example, the distance between the ophthalmic lens 2 and/or the receiving site 41 in the lens carrier 5 is at least substantially the same as the distance between the ophthalmic lens 2 and/or the receiving site 41 in the lens carrier 5 and the adjacent ophthalmic lens 2 and/or the adjacent receiving site 41 in the directly adjacent lens carrier 5. This simplifies handling and/or positioning of the ophthalmic lens 2, in particular on the transport rail T1 at the processing device 3 for loading and unloading the ophthalmic lens 2 on the processing device 3.
In the illustrated embodiment, the distance a between the centers of the receiving locations 41 of the lens carrier 5 is about 130mm, with an error tolerance of 10mm. The length l of the lens carrier 5 is preferably twice the distance a, i.e. about 260mm, with an error tolerance of 10mm. The width b of the lens carrier 5 is preferably about 220mm with an error tolerance of 10mm.
A further aspect of the invention, which can also be implemented independently, is that the width of the conveyor 4 and/or the conveyor belt 6, 6' is preferably determined by the width of the lens carrier 5, in particular by the number of transport tracks.
Preferably, the width of the transport tracks T1, T2 corresponds at least to the width b of the lens carrier 5.
Furthermore, the width of the conveyor belts 6, 6' preferably corresponds in each case to the number of transport tracks per conveyor belt. In other words, the width of the conveyor preferably corresponds at least to the number of transport tracks multiplied by the width b of the lens carrier 5.
In the example of embodiment, the width of the conveyor belt 6, 6' is in each case at least the width b of the lens carrier 5, i.e. at least about 220mm, taking account of error tolerances.
The width of the conveyor 4 is preferably at least equal to the number of conveyor tracks times the width b of the lens carrier 5.
In the case of a plurality of conveyor belts, i.e. in the case of at least two conveyor belts 6, 6', the width of the conveyor 4 preferably corresponds at least to the number of conveyor belts 6, 6' times the width b of the lens carrier 5, i.e. preferably at least a multiple of about 220mm, taking into account error tolerances.
In the case of mutually spaced conveyor belts 6, 6', the width of the conveyor 4 preferably corresponds at least to the number of transport tracks T1, T2 times the width b of the lens carrier 5, in particular plus the distance between the conveyor belts 6, 6'.
According to the present solution, the width of the conveyor 4 is preferably at least twice the width b of the lens carrier 5, i.e. at least about 440mm in the illustrated embodiment, in particular plus the distance between the conveyor belts 6, 6', taking into account error tolerances.
In the embodiment with two transport tracks T1, T2 on the common conveyor belt 6, the width of the conveyor belt 6 corresponds to the width of the conveyor 4, preferably at least twice the width of the lens carrier 5.
In addition to the above-described embodiments of the lens carrier 5, narrower variants of the lens carrier 5 are also conceivable, which are known to the skilled person. For example, the length l is between 245mm and 265mm, in particular about 250mm, the width b is between 120mm and 130mm, in particular about 125mm, and/or the distance a between the receiving sites 41 is between 110mm and 135mm, in particular about 130mm. Of course, other dimensions are also contemplated.
Furthermore, embodiments known per se, in particular stackable, can also be used, such as for example a double tray of the lens carrier 5 can be used. In case the lens carriers 5 are stacked one on top of the other, it is useful to consider their height. For example, it is possible to raise or lower the respective height of the additional lens carrier 5 by means of the conveying device 4 or the processing device 3.
