Description
- 1. Field of the Invention
- The invention relates to a device for deblocking optical glasses (lenses), in particular, spectacle lenses, which are fastened on a block, respectively. The device comprises at least one securing device on which a lens is supported and which has an opening for the block suspended from the lens. The device comprises at least one holding-down device for pressing the lens supported on the securing device against the securing device.
- 2. Description of the Related Art
- When manufacturing lenses of the aforementioned kind, the concave sides, inter alia, must be machined, for example, by milling, grinding, or polishing. The lenses to be processed are fastened by means of a low-melting alloy, whose melting point is approximately 55° C., on a so-called block. After completion of the individual processing steps, the lenses must be detached from the block. This separation of lens and block is commonly referred to as deblocking. This is carried out presently by hand. The lens fastened on the block projects laterally past the block. For deblocking by hand, a piece of tube is employed and the block is positioned in the tube opening. The diameter of the tube is of such a size that the lens, which radially projects relative to the block, will rest on the rim of the opening of the tube. The upright tube is then struck on a hard surface so that, as a result of the impact impulse, lens and block will separate. The block then falls through the tube downwardly, while the lens remains in the hand of the operator. This manual deblocking process is cumbersome and monotonous labor.
- Austrian patent 407 967 already discloses a device for automatic deblocking. In this device, a carriage or slide, on which at least one holder for a lens with a block connected thereto is provided, is movable along a guide. The guide is part of a frame which is supported on a stand to be moveable in the vertical direction. For receiving the optical glasses (lenses) together with the blocks fastened thereto, the frame is lowered relative to the stand, the holders being open during this procedure. After closing the holders, the frame is again lifted and the carriage or slide is moved along the guide provided on the frame to the separating station. The frame is then lowered at great speed so that the jaws of the holder strike a plate of the separating station, and the acceleration force acting on the block now separates block and lens.
- A disadvantage of this known device is that, for lowering the frame at great speed in order to realize deblocking, special piston-cylinder units for moving the frame must be employed which must have special venting valves in order to be able to reach the required high speed. This leads to increased manufacturing costs. Also, a change of the impact speed of the holder on the plate of the separating station is possible only with complex modifications. For this purpose, the piston-cylinder units have to be exchanged or the venting valves have to be modified such that a changed venting action can be achieved. The use of an electric motor drive for adjusting the frame (instead of the piston-cylinder unit) would require a relatively great manufacturing expenditure. Moreover, in this known configuration the mass to be moved for the deblocking process is relatively great so that high acceleration forces must be exerted causing great forces to be absorbed by the bearings.
- A device for manual deblocking is also known from U.S. Pat. No. 3,091,062. The block is inserted into an upright standard so that minimal play relative to the standard remains. At the upper end of the receiving standard a ring is arranged which is pivotable relative to the standard by means of a lever and projects past the upper edge of the standard on which lens is supported. By pivoting the ring in the upward direction, the lens is removed from the block. The block, as a result of the exerted tilting force, is canted relative to the standard so that no additional securing device is required for the block. The one-sided force application onto the lens with this type of deblocking device results in a relatively great risk of breakage of the lens. Also, an automated operation of the device of U.S. Pat. No. 3,091,062 is not taught and, moreover, would not be possible with a device of the this kind.
- It is an object of the present invention to provide an improved device of the aforementioned kind which can be produced less expensively.
- In accordance with the present invention, this is achieved in that at least one striking device is provided which has a striking member movable from below against the securing device for striking the securing device, wherein the securing device and the holding-down device are movably supported against a spring-elastic restoring force in the direction of the impact or striking movement of the striking member.
- In the device according to the invention, the masses which are to be moved upon deblocking can be reduced, and the device can be manufactured in a simpler way. Moreover, the deblocking process can be performed more reliably wherein the number of rejects in the form of lenses damaged by deblocking is reduced.
- In an advantageous embodiment of the invention, the securing device in the area of the support of the lens is of a sleeve-shaped configuration wherein the block suspended from the lens is arranged within this sleeve-shaped area at a spacing to its inner wall. In this way, a simple securing device is provided wherein a deblocking device according to the invention can comprise several such securing devices with different diameters and/or the securing devices can be adjusted for receiving different sizes of lenses or blocks or they can be exchangeable.
- It is expedient to provide the securing device with an anvil or support on a lower side opposite the lens resting on the securing device. The anvil should preferably be arranged centrally underneath the lens or the block suspended therefrom. This anvil or support serves for receiving the impact exerted by the striking member so that the impact acceleration detaching the lens from the block is transmitted via the anvil onto the securing device.
- In the drawing:
- FIG. 1 is a side view of the device according to the invention;
- FIG. 2 is a plan view of the device according to the invention;
- FIG. 3 shows a section along the line A-A of FIG. 1 (the holding-down device and the striking device are not illustrated in section);
- FIG. 4 shows a lens attached to a block in a side view (enlarged scale);
- FIG. 5 shows the lens on the block in a top view (enlarged scale); and
- FIG. 6 shows a bottom view of the lens on the block (enlarged scale).
- FIGS. 4 through 6 illustrate in different views the object to be manipulated by the deblocking device of the present intention. On a
metal block 1, which in this illustrated embodiment has aconical portion 2 and acylindrical portion 3 and is provided with adepression 4 arranged centrally and open in the downward direction, is fastened by means of a low-meltingalloy 5 to thespectacle lens 6 to be processed whose concave side is to be machined. Theblock 1 can have different shapes and different sizes depending on the type of the optical glass (lens) to be treated. Theaforementioned block 1 with the easilymeltable alloy 5 is an auxiliary device with which thelens 6 to be processed is adjustable and positionable relative to the individual tools. The connection between thelens 6 and the easilymeltable alloy 5 is of satisfactory or sufficient strength so that the reaction power caused by the tools when processing the lens can be transmitted safely and reliably onto theblock 1 inserted into a machine tool. After completion of processing of thelens 6, the lens and the block must be separated. The device described in the following is provided for this purpose. - In the illustrated embodiment
several securing devices 8 for blockedlenses 6 are provided on acarriage 7. Two rows of fivesecuring devices 8 are provided. Thecarriage 7 is supported to be movable alongguide rails 10 by means of glide shoes 9. The guide rails 10 are fastened on amachine frame 11. For moving the slide orcarriage 7, atoothed belt 12 is provided on which thecarriage 7 is secured by means of a holdingpart 13. Thetoothed belt 12 is of a continuous or closed configuration and runs on one side about adeflection roller 14 rotatably supported on themachine frame 11. The other side is provided with a drive roller (not visible in the illustration) driven by an actuator. In this way, therespective securing device 8 can be moved in an automated and program-controlled way into the required position in which deblocking of thelens 6 resting on the securing device is carried out. - Moreover, a loading station can be provided, which is not illustrated in the drawing, for supplying the securing
devices 8 with the blocked lenses. In this connection, thecarriage 7 can also be positioned by program control in order to load the respective securing device. In place of an electric actuator for thecarriage 7, it is possible to provide a pneumatic adjusting devices instead. - For pressing an optical glass or
lens 6 to be deblocked against the securing device, a holding-down device 15 is provided. In the illustrated embodiment, the holding-down device 15 is secured on apiston rod 16 of a pneumatic piston-cylinder unit 17 having apiston 18 acting via both ends. In the activate state of the holding-down device 15, air pressure loading the piston is present in thecylinder chamber 19. When a force is exerted onto thepiston 18 which acts against this air pressure and is greater than the air pressure, thepiston 18 is moved by reducing thecylinder chamber 19 against this air pressure so that the air pressure is increased. In this way, a kind of (pre-tensioned) air spring is formed against whose spring-elastic restoring force the holding-down device 15 can be moved when a correspondingly great force is exerted. In place of such an air spring device, or in addition thereto, a pressure spring could be provided, for example, between an adjusting device of the holding-down device 15 and the holding-down device 15; the holding-down device 15 can then be moved against the spring-elastic restoring force of this pressure spring. - The
securing devices 8 are sleeve-shaped at their upper area facing the support of thelens 6. Aninner sleeve part 20 is provided which is connected with anouter sleeve part 21. Aplastic sleeve 22 is arranged between the inner and theouter sleeve parts rings inner sleeve part 20 and of theplastic sleeve 22. Thelens 6 is supported on the O-ring 23. The holding-down device 15 rests on thelens 6 and optionally on the outer O-ring 24. Theblock 1 suspended from thelens 6 projects through theopening 45 of the securingdevice 8 into the interior of the sleeve-shaped area of the securingdevice 8 and is spaced relative to theinner wall 25 of theinner sleeve part 20. - The sleeve-shaped upper area of the securing
device 8 is closed off in the downward direction by a slantedly extendingguide surface 26. Thisguide surface 26 opens into anejection opening 27 for thedeblocked block 1. Theblock 1 which has been deblocked from thelens 6 falls onto theguide surface 26 and then glides along it through the ejection opening 27 into aguide tube 28 which opens into a receptacle (not illustrated in the drawing) for theblocks 1. - The
securing device 8 is axially slidably arranged in aglide sleeve 29 relative to the glide sleeve. Theglide sleeve 29 is arranged in asupport sleeve 31 which is connected to the frame of the slide orcarriage 7. Acoupling nut 32 is threaded onto the lower end of thesupport sleeve 31 and forces anelastic ring 33 against the lower end face of thesupport sleeve 31. Theelastic ring 33 projects inwardly somewhat past thesupport sleeve 31, and theglide sleeve 29 rests on theelastic ring 33 in this area. Thesupport sleeve 31 and theglide sleeve 29 are flush with one another at their upper ends, and on the upper end faces of these sleeves a dampingring 34 is positioned. In the lower end position of the securingdevice 8, ashoulder 30 of the securing device, where the diameter is reduced, rests on the dampingring 34. At the location where theshaft 35 of the securingdevice 8 projects downwardly from thecoupling nut 32, anelastic rubber ring 36 is secured on theshaft 35 and surrounds it in a circular ring shape. Thiselastic rubber ring 36 provides a spring-elastic element against whose spring-elastically acting restoring force the securingdevice 8 can be moved upwardly in the axial direction by a small stroke. Abolt 37, secured in thesupport sleeve 31 and projecting into a corresponding recess in the area of theshoulder 30 of the securingdevice 8, provides a securing action against relative rotation. - On the lower end of the
shaft 35 an anvil orsupport 38 is arranged and connected to theshaft 35. It is positioned centrally underneath thelens 6 or itsblock 1 suspended therefrom. - A device according to the invention comprises moreover a
striking device 39 which comprises a strikingmember 40 in the form of a type of a hammer. The strikingmember 40 is secured on thepiston rod 41 of a piston-cylinder unit 42 and, in its inactive rest (initial) position before carrying out a strike, is positioned at a spacing from the securingdevice 8 or itsanvil 38. By loading the piston-cylinder unit 42, the strikingmember 40 is accelerated from below in the direction toward the securingdevice 8 and carries out a strike onto the securingdevice 8 when impacting theanvil 38. By means of this impact, an acceleration is exerted onto the securingdevice 8 wherein theshaft 35 is moved relative to theglide sleeve 29 with compression of theelastic rubber ring 36 in thedirection 46 of the impact movement. Moreover, the holding-down device 15 is also moved in the upward direction by the upwardly moved securingdevice 8. The acceleration exerted onto the securingdevice 8 is transmitted onto thelens 6 so that theblock 1 as a result of its inertia becomes detached from thelens 6. After the impact energy has been received by the spring-elastic bearing devices of the securingdevice 8 and of the holding-down device 15, thedevices device 8 is damped by the dampingring 34. The O-rings lens 6. - When attaching a lens on a block, an outwardly projecting nose43 (compare FIG. 6) can be produced on a peripheral location. In order to ensure a proper deblocking action despite of this nose, a
slot 44 may be provided on theinner sleeve part 20 which extends in the axial direction across the length of thesleeve part 20. When loading thesecuring device 8, care must be taken that anose 43 which may be present is positioned above this slot so that thisnose 43 can move through thisslot 44 when theblock 1 drops. In the case that an automated loading device is provided, the lens which is gripped by a lens holder could be rotated, for securing the correct angular position of thenose 43, about a central longitudinal axis extending through the lens and the block until the nose of theblock 1 rests against a stop which will position the nose properly. - Different modifications and alterations of the illustrated embodiment are conceivable and possible without leaving the realm of the invention. For example, the support of the securing device that is movable relative to a spring-elastic restoring force could also be realized in a different way then the one illustrated. For example, the
shaft 35 of the securing device could also be attached to a bearing block on an elastic material which, in turn, is fastened on the frame of the carriage. The movement of the securingdevice 8 would then be realized against the elasticity of the material of the bearing block. Also, thebearing device 8, in place of the sleeve-shaped area on which the lens to be deblocking is supported, could have a support which is adjustable with regard to its diameter in order to be able to deblock lenses or blocks of different diameters with one and the same securing device. A securing device could be provided in the area of the support of the lens with several jaws surrounding a receiving opening for the block and positioned at a spacing from one another in the circumferential direction, wherein the diameter of the receiving opening is adjustable by scissor-type members, as disclosed already in the prior art deblocking device described supra. - In principle, it would also be conceivable and possible to eliminate the slide or
carriage 7. The securingdevices 8 would thus be stationary relative to themachine frame 11. In this situation, each securingdevice 8 would be provided with its own holding-down device 15 and itsown striking device 39. Loading of one or several securing devices could be carried out by hand. - While specific embodiments of the invention have been shown and described in detail to illustrate the inventive principles, it will be understood that the invention may be embodied otherwise without departing from such principles.
