Description

The invention relates to a system and / or device (s) for producing and / or further processing a glass body with at least one of its shaping and / or processing further serving and / or at least one device for producing and / or further processing a glass body.

The present invention relates to a device, apparatus and / or plant which serves for the production and / or further processing of a glass body and can be used for all known methods for glass production.

Such devices are industrially assembled regularly to a plant. Devices within the meaning of this invention are structural and / or functional components of devices in the context of this invention.

So far, conventional manipulators are used in the production and further processing of glass bodies, in particular hollow bodies made of glass. These manipulators serve primarily loading and unloading during the manufacturing and / or further processing process. The manipulators are coupled directly to the glassmaking or glassworking device via a transmission. You can alternatively have a separate mechanical drive.

From the US 4,104,046 A For example, a temperature control system for a glassmaking machine is known. The system includes means for automatically determining whether cooling air has to be supplied. The device causes, if necessary, the supply of cooling air to the individual glass forming units. The respective target temperature can be kept stable in all glass forming units, so that a uniform quality level can be maintained.

The DE 10 2012 103 773 A1 discloses an apparatus for producing hollow bodies from a molten glass. A carrier mechanism moves, by means of a carrier, a preform which serves to receive a drop of molten glass between two working positions. The at least one drive of the support mechanism is at least one servo drive.

The task of loading and unloading in particular is that glass products are picked up and moved from an initial position to a second position.

As a glass body according to the present invention, the glass blank is understood. Both, d. H. the glass blank or the glass body are hereinafter also referred to as product.

Depending on the design of the product, different methods are known for shaping and / or further processing. The shaping takes place in particular by pressing, blowing, nozzles, spinning, rolling or drawing or combinations thereof. The further processing of the molded products relates in particular to the possible process steps of engraving, grinding, laser cutting, coating z. B. with colors, films, and drilling.

Hollow glass is produced, for example, in several process steps by pressing, blowing, spinning, or by combinations of these techniques. As a combined manufacturing method, for example, the blow-and-press method or the press-blow method are known. For the production of z. As tableware, technical glasses or artisan glasses, for example, devices are used in which the glass production is carried out by the press-blow process, the system for producing such a product via a generally carousel-shaped device with usually at least one Segment for receiving, inter alia, the preform and the press-blower and the bottom, at least one takeout device, at least one transport device, at least one generally carousel-shaped device for receiving at least one melting device and other devices may have.

The so-called carousel usually includes preforming devices, press-blowing devices, ground facilities. In the further course of the process, the products are taken from a frequently also carousel-shaped takeout device with removal device arranged thereon, also called takeout device, and partially turned over and fed via loading and unloading conveyor belts for the purpose of completing the production and / or further processing. These include o. A. Devices with melting devices, grinding devices, all of which are performed according to the prior art on structurally complicated and expensive machines.

The glass article which has undergone the shaping process is usually tempered by defined slow cooling in a cooling zone, which in addition reduces stresses resulting from the shaping in the glass body.

Other methods of glass production are, for example, the float process in which flat glass is pulled, rolled or cast for production. Tubular glass is produced, for example, by continuous drawing.

Consequently, the system usually comprises various devices and / or various devices which pass through the liquid glass melt until the final glass mold is formed during the manufacturing process.

The known devices of a system comprise - explained with reference to the press-blow process - especially, but not exclusively at least one feeder, at least one preforming device, at least one pressing device, at least one blowing device, at least one neck ring, at least one ground station and at least one finished mold, at least one removal device, at least one melting device, at least one loading device for the melting device and at least one removal device for the melting device. Furthermore, gravure devices, grinding devices, laser separation devices and coating devices are frequently provided.

For systems that follow the blow-blow technology, press technology, spin technology, float technology, such facilities are equally present, as far as they are necessary for the execution of this technology. In principle, the same applies, for example, to systems that follow hardening technology, welding technology or adhesive technology.

The invention relates not only to these aforementioned examples, but to all embodiments of glass-making and / or glass processing equipment, devices and facilities.

Insofar as the terms system, device, device are used in the description of the prior art, this understanding of terms also applies in the context of the description of the invention.

In systems of the aforementioned type for the production of glass bodies is often u. a. a carousel used. In one revolution of the carousel, a drop of molten glass is fed via a feed device to a preform. The preform is regularly associated with one of the formation of the hollow body serving means, in particular a pressing device, a neck ring and a blowing device in connection. The molding of a hollow body from a molten glass is carried out in such a way that first the Kölbel (corresponds to glass blank) is produced. This happens because the glass gob is pressed in cooperation with the so-called preform, neck ring and a so-called plunger to the Kölbel. In a subsequent process part cycle of the Kölbel is formed by means of the blowing device under their interaction with neck ring, so-called bottom and finished shape to the hollow body. In this case, the so-called floor can be moved by a predefined movement under the Kölbel. Due to the vertical movement of the soil under the Kölbel ausgelend by gravity shaping of the hollow body can be driven. Furthermore, the finished molding of the hollow body is carried out by a blowing device.

Furthermore, the systems for the production of glass bodies have at least one carousel-shaped takeout device with removal devices. It is regularly adjacent to the carousel. Both devices interlock. The takeout device takes over the product by means of its removal devices from the carousel and feeds it to a transport device for further processing.

A transport device is provided between the takeout device and a loading device which transmits the glass body to a melting device. In the subsequent melting device further processing of the product takes place.

Subsequently, the product is removed by a further removal device and fed to the cooling area. This can be further processing steps such. As the engraving, grinding, coating and / or drilling connect.

These aforementioned method steps are usually used in the press-blow technology. Regardless of this, in the case of glass-making and / or glass-processing devices, irrespective of which of the above. Technologies they follow, in particular the process steps of the discharge and / or loading in the process of manufacturing and / or further processing an important role. These process steps of unloading and / or loading usually follow the same principles, no matter what technology follows the device for manufacturing and / or further processing.

In the following, by way of example only, without any limitation of the invention being involved, the unloading and loading process according to the prior art and subsequently according to the invention will be described by means of a device which follows the so-called press-blow technology

Removal of press-blower device:

After completion of the blowing process on the arranged on the so-called. Carousel, press-blow device, the products must be accurately taken time and very precise from the device. The temporal synchronization of the removal from the press-blow device is important, since only at one peripheral point a subsequent device (taker) has a same peripheral speed to remove the finished products without error.

For the removal of the largely finished in its basic form product, it is also very important that no damage takes place on the hot surface or on the contour itself. These damages can be caused by unsuitable tools (surface damage) and / or by misadjustment of the process parameters (contour changes). In the prior art, the removal of the pre-pressed and blown out in the further process glasses takes place by a taker of a takeout device, which is coupled to the press-blow device. This is realized by mechanical coupling links (gears, differentials, cardan joints). The mechanical coupling is adjustable from the outside via a differential (gear).

The takeout device is also, like the press-blower mounted on the rotating carousel, a continuously rotating device having a smaller pitch diameter and fewer work stations on a circular path as compared to the press-blow device. The taker, d. H. the take-off device of the take-out device is positioned relative to the press-blow device such that at a position on the circumference both devices intermesh with one another.

A workstation of the extractor consists essentially of a gripper and a floor. The gripper with its entire mechanics is height-adjustable on the main axis of rotation. This again requires additional mechanical coupling links, which in turn increase the susceptibility to failure and extend the repair time. The actuation of the moving gripper takes place via a cam control. The cams are firmly mounted on a curve, the entire curve is usually manually adjustable via a mechanically extensive mechanism from the outside. The energy supply to the grippers via a compressed air rotary transformer. Furthermore, pneumatic valves for switching and adjusting the speed and pneumatic cylinders on the grippers are required. The gripper mechanism as well as the height adjustment must be lubricated. This is usually realized by means of a central lubrication, which in turn requires an oil rotary transformer.

All rotary joints have internal seals that have only a limited life and in this device are accessible only by the complete removal of the entire extractor and thus cause a long downtime of the entire system in case of repair.

The grippers are usually still in addition to 180 ° pivotable about the gripper axis to put products turned on a conveyor belt can. This turning mechanism is either mechanically coupled to the rotary motion of the gripper carousel or the grippers are rotated by a pneumatic actuator about its own axis. The mechanical coupling requires one or more curves, levers and often spring return.

The optional bottom is located axially under the grippers. The bottom may be formed with many holes to ensure cooling of the product during transport from the press-blower to the conveyor belt. Prior to delivery of the product to the conveyor belt, the bottom is swung away by contact with a housing and the product falls into the gripper, which have prevented until this time only the tilting movement. The automatic axial alignment of the soil in the basic position under the grippers takes place after the transfer of the product to the conveyor belt by a spring mechanism.

Overall, the existing taker is very complex and consists of many components. As soon as only one component is defective, if z. B. only one seal of the rotary distributor is leaking, the entire taker is defective. The accessibility is extremely difficult due to the complexity and so usually requires the expansion of the entire Herausnehmers, which in turn means the stoppage of the entire system (press-blow device, takers and subsequent devices / facilities). For maintenance or repair of the extractor, the system as such, in particular the press-blow device, previously empty. To restart the system after the standstill due to repair, it is necessary to heat the devices and equipment to operating temperature to ensure the quality of the product. This means a high loss of time and production.

With regard to the takers treated here, the state of the art does not constitute a satisfactory solution due to the large number of components involved in play and wear.

Loading the melting device:

To load the melting device, the products must be loaded exactly in time and very precisely standing upside down. The time synchronization of the loading of the melting device is important because the loading device, a rotating belt loader, only at a peripheral point has the same peripheral speed as the melting device to pass the finished products in their basic form error-free to the hanging suction cups of the melting device.

For the production of the product, it is also very important that no damage takes place on the hot surface or on the contour itself. These damages can be caused by inappropriate tools (surface damage) and by collisions after misadjustment of the process parameters (contour changes).

In the prior art, the loading of the press-blown glasses is carried out by the loader, which is mechanically coupled to the melting device. This is realized by mechanical coupling links (gears, differentials, cardan joints). The mechanical coupling is adjustable from the outside via a differential gear). The loader is also, like the melting means, a continuously rotating device having a smaller pitch diameter and fewer work stations on a circular path as compared to the melting means. The loader is positioned towards the ablation device so that both devices engage one another precisely at a position on the circumference of the ablation device.

A workstation of the loader consists essentially of a gripper. The gripper with its entire mechanics is height-adjustable on the main axis of rotation. This again requires additional mechanical coupling links, which in turn increase the susceptibility to failure and extend the repair time. The actuation of the moving gripper takes place via a cam control. The cams are firmly mounted on a curve, the entire curve is usually manually adjustable via a mechanically extensive mechanism from the outside. The energy supply to the grippers via a compressed air rotary transformer. Furthermore, pneumatic valves for switching and adjusting the speed and pneumatic cylinders on the grippers are required. The gripper mechanism as well as the height adjustment must be lubricated. This is usually realized by means of a central lubrication, which in turn requires an oil rotary transformer.

All rotary joints have internal seals that have only a limited life and are accessible in this device only by the complete removal of the entire loader and thus cause a long downtime of the entire system in case of repair.

The grippers are usually still in addition to 180 ° pivotable about the gripper axis in order to use upright on the conveyor belt products with product bottom upwards directed into the melting device can. This turning mechanism is either mechanically coupled to the rotary motion of the gripper carousel or the grippers are rotated by a pneumatic actuator about its own axis. The mechanical coupling requires one or more curves, levers and often a spring return.

The existing loader is overall very complex and consists of many components. As soon as only one component is defective, if z. B. only one seal of the rotary distributor is leaking, the entire loader is defective. The accessibility is extremely complicated by the complexity and thus usually requires the removal of the entire loader, which in turn means the shutdown of the entire subsystem (loader, melting device, takers), because the subsystem previously drained empty and then brought back to operating temperature after repair must become.

With regard to the loader treated here, the state of the art does not represent a satisfactory solution due to the large number of components involved in play and wear.

Removal Melting Device:

After completion of the Abschmelzprozesses on the melting device, the products must be accurately timed and very precisely removed from the device. The temporal synchronization of the removal from the melting device is important, since only at one peripheral point a subsequent device (taker with circular path) has the same circumferential speed to remove the finished products without error. For the removal of the finished product, it is also important that no damage takes place on the surface or on the edge itself. These damages can be caused by unsuitable tools (surface damage of the gripper or suction materials) and / or by misadjustment of the process parameters (contour changes).

In the prior art, the removal of the melted glasses by the taker takes place, which with the Melting device is mechanically coupled. This is realized by mechanical coupling links (gears, differentials, cardan joints). The mechanical coupling is adjustable from the outside via a differential gear). The taker is also, like the melting means, a continuously rotating device having a smaller pitch diameter and fewer work stations on a circular path compared to the melting means. The taker is positioned to the meltdown device such that at one circumferential position, both devices intermesh. A workstation of the extractor consists essentially of a gripper. The gripper with its entire mechanics is height-adjustable on the main axis of rotation. This again requires additional mechanical coupling links, which in turn increase the susceptibility to failure and extend the repair time. The actuation of the moving gripper takes place via a cam control. The cams are firmly mounted on a curve, the entire curve is usually manually adjustable via a mechanically extensive mechanism from the outside. The energy supply to the grippers via a compressed air rotary transformer. Furthermore, pneumatic valves for switching and adjusting the speed and pneumatic cylinders on the grippers are required. The gripper mechanism, as well as the height adjustment, must be lubricated. This is usually realized by means of a central lubrication, which in turn requires an oil rotary transformer.

All rotary joints have internal seals that have only a limited life and in this device are accessible only by the complete removal of the entire extractor and thus cause a long downtime of the entire system in case of repair.

The grippers are usually still in addition to 180 ° pivotable about the gripper axis to put products turned on a conveyor belt can. This turning mechanism is either mechanically coupled to the rotary motion of the gripper carousel or the grippers are rotated by a pneumatic actuator about its own axis. The mechanical coupling requires one or more curves, levers and often a spring return.

Overall, the existing taker is very complex and consists of many components. As soon as only one component is defective, if z. B. only one seal of the rotary distributor is leaking, the entire taker is defective. The accessibility is extremely complicated by the complexity and thus usually requires the removal of the entire Herausnehmers, which in turn means the stoppage of the rest of the rest of the system (melting device, takers and subsequent devices), because the system before partially drove empty and then after the repair must be brought back to operating temperature.

With regard to the takers treated here, the state of the art does not constitute a satisfactory solution due to the large number of components involved in play and wear.

The aforementioned devices, in particular the carousel, the take-out device, the preforming device, the pressing device, the blowing device, the combined press-blow device have in the prior art highly complicated, maintenance-prone, expensive components in the form of pneumatic cylinders whose Wear, environmental pollution, hazards to work safety often lead to associated costly protracted production losses. The use of mechanical gear in known from the prior art devices and devices has the consequence that the mechanical adjustment of movements of the devices and devices to the requirements of the product can be achieved only by high risk to the operator. The high security risk arises from the required intervention in the device or device in operation. The adaptation includes the setting of mechanical assemblies, work for assembly and / or disassembly and / or replacement of mechanical components. To minimize the security risk, the device or device concerned must be stopped, which in turn means a huge loss of time and consequent significant loss of production time.

To ensure the proper function and a consistently high quality of the product a variety of mechanical guides and / or centering is provided. These are in turn subject to wear and lead to high maintenance. The maintenance, as described above, the shutdown of the device or device with all the aforementioned negative consequences.

To avoid the wear of the aforementioned components and to increase their life, the mechanical elements of these components must be permanently lubricated and maintained.

The above-described embodiments of the prior art result in increased environmental pollution. Due to the use of lubricants, the risk of fire continues to increase. Likewise, there is a considerable risk of slipping, since it can not be prevented that the lubricant deposits on the floor.

The invention is therefore based on the object to provide a system, one or more device (s) and at least one device for producing and / or further processing of glass bodies, the disadvantages of the prior art known devices, devices or devices in Essentially avoids. In addition, it is an object of the invention to provide a system, at least one device and at least one device for the production and / or further processing of glass bodies, which is exactly controllable and reproducible in their workflows.

In particular, the task is the system or the at least one device not only in relation to the removal of the product, the loading of the melting device, the removal of the melting device, but also the other facilities for the provision of a molten glass, for the supply this molten glass into a preforming mechanism or to a mold, for the design of the press-blow process, the blowing process, the pressing process, for engraving, for grinding, for laser separation, for the coating and / or for the To simplify drilling.

The at least one device, but also the system, as well as the at least one device should moreover be produced cost-effectively, with the further aim of achieving a standardization of the assemblies and replacement parts by providing substantially uniform components.

Furthermore, the existing in the prior art variety of involved play and wear-prone assemblies should be significantly reduced.

It is another object of the invention to produce the glass body faster, reproducible, in high quality and maximum yield. In particular, it should be ensured that the (re-) commissioning of the system or device or device can be simplified by electronic control and executed while dispensing with complex mechanical settings or changes.

Furthermore, the work safety is to be increased, the environmental impact and the risk of fire are significantly reduced.

The above-mentioned tasks relate - which is readily apparent - not only to the device, the system consisting of several devices, but also to the (single or multiple) devices of the device, as well as the system.

The object is solved by the features of patent claims 1, 10 and 17.

For reasons of simplification, the invention will be explained in more detail below using the example of the press-blow process.

The at least one device and / or at least one device is used to shape the glass blank and the further processing of the glass blank into a glass body and / or its loading and unloading and / or transport.

Under a glass body in the context of the invention are in addition to the above description in particular hollow body of any kind, solid, flat glass, tube glass, technical glasses, art glass, regardless whether designed as a single-layer or laminated glass understood.

The at least one device is used for the production and / or further processing of a glass body. It has at least one device serving for its shaping and / or further processing, wherein the at least one device comprises at least one robot. Accordingly, the system also has a corresponding device.

According to the invention, the at least one device is used for the production and / or further processing of a glass body, wherein it is provided with at least one of its shaping and / or its further processing device, and wherein the at least one device is associated with at least one robot. According to the invention, the robot moves in a three-dimensional direction around the product and / or the tool. The robot is simply in the changeover or in the change of the movement sequence, whereby a rapid adaptation to different shapes and characteristics of the further processed products is possible.

The invention will be described beyond the loading and unloading process - also - with respect to the further method steps and the associated devices as follows:
To accommodate a part of the facilities, the plant typically has at least one device as a so-called carousel. For its part, the carousel preferably comprises a base plate for receiving the devices which serve to shape and / or further process the glass blank to form the glass body. The devices include in particular the preforming device, as well as the press-blow device, which are each arranged on one of the preferably 12 or 18 segments of the carousel.

Disclosed is an apparatus for producing and / or further processing a glass body from a glass melt, which comprises at least one device which serves for shaping a glass blank and / or further processing it to form a glass body. The at least one device comprises at least one robot. In addition, it is alternatively provided that the at least one device is associated with at least one robot.

For example, in the case where the preforming device comprises the at least one robot, a robot may be disposed in or replace the mechanism of the preforming device. The robot is thus part of the preforming device in this example. In this case, a preferred embodiment of the invention provides that the at least one carousel and / or a segment of the at least one carousel has at least one robot and / or that at least one of the two embodiments is a robot.

In the other example case in which the device is assigned at least one robot, the robot, for. B. in addition to other robots, adjacent to the device concerned for the production of the glass body to be arranged. The robot is therefore only associated with the device (for example preforming device or the takeout device of the takeout device). In contrast to the first example, the robot in the second example is not a structural part of the device, but a functional part.

In this case, the at least one robot is preferably arranged stationary outside the device, for example stationarily outside a carousel and / or the takeout device for producing glass bodies. In this embodiment, the at least one robot can specifically engage the carousel and / or takeout from the outside during operation of the device and execute the movement of the preform or the movement of the supporting bottom and / or the movement of the gripper of the removal device of the takeout. In this case, the robot foot does not follow the continuous circulating movements of the carousel. In addition to or instead of gripping, sucking, pushing, rolling, blowing or similar picking up of the product may take place.

The robot can be arranged with one foot on the carousel of the apparatus for producing the glass body. The arrangement of the foot can also take place on or on a segment of the carousel. It is also possible to position the foot of the robot outside the apparatus for producing the glass body.

The decentralized and mechanically decoupled design allows a simple change of at least one robot or a simple maintenance without time-consuming disassembly, especially on the carousel.

The two examples are merely exemplary and in no way exclusively related to the preforming device or takeout. Of course, both examples can also be applied to all other devices of the respective device and / or system for the production and / or further processing of glass bodies, in particular to the loading and unloading devices.

In both alternatives, the device for producing glass bodies preferably has at least one feed device in the form of a robot. By means of the feed device, a glass drop emerging from the molten glass is fed to the preform.

The use of a robot greatly improves the accuracy of feeding the glass drop from the feeder to the preform. In the control of the device for the synchronization of the robot preferably electronic (zero-backlash) gearboxes and speed profiles are stored, with which motion sequences can be controlled speed, angle synchronously and repeatable. As a result, it is largely avoided that the drop delivery does not take place centrally in the preform and the drop may optionally impinge on the wall of the preform. The latter would lead to a significant loss of quality and yield of the device.

The movement speed corresponds to a predetermined period of the rotational speed of the carousel. The advantage of the invention is that the bilateral speed of the drop as the drop leaves the feeder and enters its preform is matched to the rotational speed of the carousel. The point in time at which the feeder and the center of the carousel preform overlap is the time at which the drop from the feeder passes into the preform. By way of example, the peripheral speed of the carousel may be 1200 mm / s. This achieves a lateral movement of 12 mm per 1 / 100th of a second. From this it can be seen what great influence results from a fluctuation of the drop transfer time to the centric position of the drop in the preform. The invention avoids the error of conventionally driven feeders in transferring the drop to the preform.

A device for producing a glass body further has a support mechanism, which moves by means of a preform carrier a preform, which serves to receive a drop of molten glass, between at least two working positions. The preform is positioned in a defined waiting position on the segment of the pressing device or the blowing device. This embodiment can be present in both alternatives of the arrangement of the at least one robot. The robot can ride along the segment of the carousel or it can be stationarily positioned outside the carousel.

The at least one robot picks up a preform in these examples. In particular, he grabs them and moves them to the drop feed position. Hereupon, the robot preferably moves the preform with the droplets toward the pressing device. Subsequently, the preform pneumatically, magnetically, mechanically or hydraulically or combinations thereof by z. B. gripping elements of the press-blow device fixed. The fixation is solvable.

After the pressing process, the at least one robot picks up the preform in the pressing device and / or in the combined press-blowing device, in particular it grips it, the fixing being released, and returns the preform back to the waiting position.

In the case where a device of rotation and / or movement of a floor or a combination thereof serves as a finished mold, preferably the robot traveling along the segment of the carousel preferably subsequently grips the floor from a defined waiting position on a segment the press-blower and moves the floor by a predefined movement under a glass blank.

The vertical movement of the bottom under a gravity blanked glass blank, the shaping of the glass blank can be positively controlled. This is followed by the final shaping of the hollow body by a blowing device or by a combined press-blower. Subsequently, the robot resets the floor to the defined waiting position. By the preferably last endless rotating axis of the robot, an optional rotation of the soil can take place during the vertical movement.

By programming the at least one robot, a simple switching or changing of the movement sequence is made possible. It is avoided that mechanical changes to the components of the device or device or their replacement - as in the prior art the case - be necessary if other glass articles are to be produced or if for other reasons optimizations of the movement sequence of the preform or the floor necessary.

With regard to the step of the "extraction-press-blower", the technical problem according to the invention described below is solved as follows:
The plant for the production of glass bodies has at least one removal device of the takeout device. It is regularly adjacent to the carousel. Both modules interlock. The removal device takes over from the carousel the product and leads it to a transport device not described in detail.

In the apparatus according to the invention, the transfer of the product from the shaping device to the transport device is carried out by at least one robot. The tasks of the robot include removal from the device, e.g. B. the press-blow device, by z. B. gripping, a possible rotation of the product by 180 °, the movement to the dispensing position and then the targeted transfer to the transport device. In addition to or instead of gripping, sucking, pushing, rolling, blowing or similar picking up of the product may take place.

The advantages mentioned in relation to the preform device result - irrespective of the further advantages described below with regard to the use of a robot - analogous to the requirements for the takeout. It is achieved that the center of the gripper tongs of the takeout at the time of removal of the hollow body coincides exactly with the defined by the neck ring center of the hollow body. Otherwise, this would lead to a significant loss of quality and yield of the device. The advantage is further that the robot is electronically adaptable to the pressing device and blowing device or the combined press-blowing device. The robot is also easy to switch or change the sequence of movements, whereby a rapid adaptation to different shapes and characteristics of the hollow body to be produced is possible.

The robot of the takeout preferably has preferably different working axes. An embodiment of the robot is such that the robot with its freely programmable axes grips the product at a pick-up position of the press-blower and displaces it to a defined discharge position by movement by means of at least one of several axes.

Another embodiment provides that the robot preferably on its last axis, preferably a turntable or has at least one other support mechanism and / or a sucker and / or a gripper and / or a magnet. At the aforementioned turntable or support mechanism may preferably be arranged more suckers, grippers or magnets. The preferably endless rotation of the last axis of the robot, the suckers, grippers or magnets are set in motion, whereby a recording of the product in the receiving position and a subsequent movement is made possible in the dispensing position. Timing with the carousel is controlled by the robot. The only achievable in the prior art point synchronization is achieved easier and more precise by the use of a robot with the aforementioned working elements by the robot can follow the circulating movement of the carousel over a definable travel path. Necessary adjustments can be simplified by using the robot.

Inventive transport devices may comprise a conveyor belt, but may also be or comprise other means for further movement of the product. The aforementioned robot passes the product z. B. on the conveyor belt.

Alternatively it can be provided that the aforementioned robot loads the subsequent melting device. Furthermore, an alternative is that the aforementioned robot hands the product over to another robot, which in turn loads the subsequent melting device with this product. These embodiments have the advantage that wear-prone, expensive and maintenance-intensive conveyor belts can be dispensed with.

In the inventive loading of the carousel-shaped device for receiving at least one melting device, the transfer of the product from the transport device to a holding assembly, z. B. to a suction cup, the melting device by at least one robot. The task of the at least one robot comprises the removal of the products from a transport device - also in the form of a robot - by z. B. gripping, a possible rotation of the product by 180 °, a movement to the melting device with reaching a synchronous position to the suction cup and then targeted delivery to the hanging suction cup of the melting device. In addition to or instead of gripping, sucking, pushing, rolling, blowing or similar picking up of the product may take place.

By handling at least one robot, a defined synchronous removal of a transport device and synchronous delivery to the melting device can be ensured. By programming the at least one robot, a simple switching or changing of the movement sequence, the gripping height or suction height, gripping force, etc. is made possible.

Incidentally, the above-described process of loading the ablation device in principle follows the above-described removal of the product.

Furthermore, the above-described embodiment of the loading and unloading is valid for any type of the aforementioned glassmaking technologies.

The product is processed further in the melting device. Here, in particular, a separation of the upper region of the product takes place.

After completion of the Abschmelzprozesses on the melting device, the removal of the glass body from the device according to the invention by the robot or the time and accurately takes place. With regard to the exact time synchronization of the removal of the glass body from the melting device by the robot, the statements of the above description for removal in connection with the takeout device apply mutatis mutandis. An exact synchronization is required for error-free adoption of the product.

According to the invention, the at least one robot also effects the transfer of the glass body from the melting device from the shaping device to a (further) transport device. When removing the glass body from the melting device, the robot performs several actions such as gripping, sucking, turning the glass body and the targeted transfer of the glass body to the transport device. By means of the takeout device, the product is supplied to the cooling area.

This can be further processing steps such. As the engraving, grinding, coating and / or drilling connect. According to the invention, the robot detects the product and moves the product relative to the tool, which is designed, for example, as a grinding wheel, drill, engraving device. The robot grasps the product by grasping it. Instead of gripping sucking, pushing, rolling, blowing or a similar recording of the product can take place.

Alternatively, the robot captures the tool and moves it relative to the product.

An advantage of both embodiments is that the robot can move in a three-dimensional direction around the product and / or the tool. The robot is also easy to switch or change the movement sequence, whereby a rapid adaptation to different shapes and characteristics of the products to be processed is possible.

Further general advantages and embodiments of the inventively provided at least one robot in the above-described devices or devices can be summarized as follows. These advantages and embodiments are understood in each case as a preferred embodiment of the invention and also disclosed in this sense.

The advantage is that the at least one robot, in particular the loading and unloading robot, is electronically adaptable to the control of the carousel of the pressing device and blowing device or the combined press-blow device, preferably including the preforming device. Equally, this applies to the control of the removal device of the takeout device and the melting device.

The peripheral speed of the carousel is often about 1200 mm / s. This corresponds to the lateral movement of 12 mm per 1 / 100th second. From this it can be seen what great influence resulting from a fluctuation of the finished product transfer time on the proper and error-free transfer. The invention proves to be advantageous because fluctuations in the time of transfer of the finished product are largely reduced. Such fluctuations have a negative effect on a proper and error-free transfer of the glass body.

By using the at least one robot, substantially all the above-described play and wear-prone coupling elements between the device main drive and the pickup are eliminated. The synchronization of the at least one robot is performed by electronic coupling with the main control of the system.

Alternatively and preferably, the robot can autonomously synchronize with the main control of the system. This can preferably be realized by attaching one or more electronic position sensors to the carousel, which reads in and / or processes and / or processes the at least one robot controller.

Likewise, the retrofitting of such a robot is comparatively easy to carry out.

In particular, the automatic movement machines can preferably work according to a constant movement pattern. It is further preferred if this movement pattern can be changed quickly and easily. Furthermore, this is understood to mean automatic actuators which preferably have different sensors and are thus able to adapt the program sequence automatically to the changes in the hollow bodies to be formed and / or the conditions of use present during their manufacture.

The at least one robot - either in its embodiment as part of the device for producing and / or further processing of the glass body, z. B. in the embodiment of the preforming device, or in its embodiment as a part stationary outside the device, for. B. the preforming device and / or the takeout - can move synchronously with the peripheral speed of the carousel, whereby a significant reduction in the absolute speed of the device is achieved. Due to this reduced speed z. B. the quality of the drop feed or removal and thus the glass body as a final product seriously improved.

In the control defined electronic gearboxes and further stored speed profiles realize the speed and angle synchronous motion sequence with an excellent accuracy of preferably up to 4 microseconds.

The robot according to the invention, which is to be used for movement and control, is preferably a multi-axis robot.

The robot consists of at least 2 moving axes and is fixedly arranged on the circumference of the press-blower. At the head of the robot is a rotation axis (also referred to above as the last axis) arranged, which z. B. can perform a 360 ° rotation angle accurate to 1/100 °. Preferably, this axis can rotate endlessly.

At the axis of rotation of the at least one robot of the loading and unloading device, preferably the turning and gripper mechanism is mechanically fastened. The turning and gripper mechanism consists of at least one working unit, which in turn can perform a rotation angle of 180 °. The movement of the above working unit of the robot according to the invention is carried out by compressed air. The required energy source (compressed air) is transmitted through hoses, which are preferably permanently mounted on the robot. The advantage is that can be dispensed with the installation of rotary distributors or wear-prone components for energy transfer. As a result, in particular seal wear and lubrication are avoided in comparison to the prior art.

The at least one robot ensures the speed and angle synchronous movement with freely programmable axes. A workstation engages the finished product by the gripper mechanism at the time of the ideal transfer. An axis of rotation, to which the work station is attached, subsequently rotates through 180 ° and sets the glass body onto an adjacent, preferably lower transport device. For this purpose, a height stroke may be required, which can be realized by the robot.

Before settling on the transport device, the glass body must be accelerated to the same speed, because at a differential speed, the glass body can fall over due to inertial moments. The necessary speed and orientation of the product in the transport direction is also made by the programmable axes of the robot.

The use of at least one robot also permits such defined synchronous removal from a transport device between the takeout device and the loader device. In addition, the synchronous transmission of the glass body from the loading device to the melting device is ensured.

Through the use of at least one robot are largely related to the prior art negative properties such. B. poor reproducibility of pneumatic cylinders whose high wear, associated production losses and above all eliminates the risk in the workflow. By using the robot according to the invention, the mechanical transmission or guides from the prior art are replaced, whereby a significant reduction in maintenance and risk in the workflow is achieved.

The at least one robot may in each case comprise at least one support mechanism and / or a sucker and / or a gripper and / or a carrier and / or a magnet and / or a production means. The manufacturing means, in particular the gripper, according to the objects to be handled, for. As preform, bottom or hollow body, simplified, changed, adjusted and adjusted.

A further embodiment of the invention provides that the at least one robot can be moved from a waiting position into a working position and vice versa.

In the waiting position, the at least one robot can be serviced and subjected to necessary repair work. Such maintenance and repair activities can be performed without interrupting the normal operation of the glass apparatus.

Moreover, it is possible that the at least one robot is driven pneumatically and / or magnetically and / or mechanically and / or hydraulically.

Different drive concepts can be used to drive the at least one robot. Preferably servo drives and / or other direct drives can be used.

The drive of the at least one robot can be a servo-electric drive. Servo-electric drives are, for example, as linear motors and torque motors.

In this way, the servo drive can be designed particularly efficient especially for fast movements that require little power and for slow movements where a high driving force is required.

The use of a servo-drive in which the power transmission is effected by electromagnetic traction causes elimination of any play and any wear between known from the prior art coupling links.

Design-identical robots can be arranged at different positions of the device or the device or device for producing the glass body. In addition, further components can be standardized in the area of the robot. A drive motor can be effectively used at various locations of the devices for driving a plurality of robots. Investment and replacement costs can be reduced through standardization. Overall, the availability of devices or devices for the production of glass bodies increases.

Another advantage is that the number of mechanical components and thus components to be serviced can be significantly reduced, which can also reduce the manufacturing costs. As a result, maintenance work can be largely avoided or maintenance intervals can be increased.

The use of servo drives allows for predictive maintenance. The current operating states, limit values, contouring errors and / or current consumption can be stored for each production setting. Reference data is compared with data of the current operating state. In this way, messages and Warnings are generated before the occurrence of an accident. Inspections or maintenance of the system are initiated before the incident, which makes revisions predictable and minimizes production and repair costs.

According to the invention, the direction of movement of the robot can run in or against the direction of movement of the device.

Due to the programmability of the at least one robot, the above movements can be carried out mutatis mutandis in the reverse direction. Ie. the pressing device and / or the combined press-blowing device can be moved to the preform. Alternatively, the blowing device and / or the combined press-blower can be guided to the ground. The two examples mentioned are intended purely as examples and in no way exclusively meant.

These aforementioned method steps are - as stated - usually used in the press-blow technology. In principle, however, there are no significant differences in systems, devices, devices that follow one of the other technologies for the production and / or further processing of glass bodies. Regardless of this, in the case of glass-making and / or glass-processing devices, irrespective of which of the above. Technologies they follow, the process steps of the discharge and / or loading in the process of manufacturing and / or further processing an important role.
