[0002] Field of the Invention

[0003] The present invention relates to a neck mould mechanism developed for rotating the upper jaw holding and carrying apparatus called neck mould, which is used in the production of glass cups, around its centre axis, and which provides more reliable and efficient results compared to existing methods.

[0004] State of the art

[0005] H28 machine is an equipment used in glass press-blowing manufacturing. This machine performs the process of placing hot glass into molds, pressing it, and then shaping it with blown air. It provides high precision and efficiency in the production of glass products and is generally preferred in the production of glasses, bottles and other glass products. Neck mould is an apparatus that functions to hold and carry the upper jaw of glasses in glass production. This apparatus plays an important role in the process of rotating and placing glass glasses. It is often used in automatic machines and ensures precise processing of glass products. Neck mould is a critical component in shaping and transporting of glass. The neck mould is generally rotated by air or torque motors to transport glass cups; however, some problems may arise in this process. While air motors may not be able to provide sufficient power due to pressure loss or leaks, torque motors may experience problems such as overload or overheating. These problems negatively affect the reliability and efficiency of the turning mechanism, leading to interruptions in the production process.

[0006] The H28 machine comprises a series of machines that perform all stages from the beginning of the glass drop production process to the formation of the finished product. This machine is configured with arms called “machine sections”. The manufacturing process comprises three stages: preforming the glass drop in the pressing stage; then, in the sagging stage, the glass in the semifinished form elongates under the influence of gravity; finally, in the blowing stage, the final shape is given to the product. During the manufacturing process, the neck mould holds the glass from the upper jaw and the glass is sagged. Neck mould rotates the glass around its central axis. Rotational movement is a step inherent in the press blowing process, and in current systems it is carried out by an external air motor or electric motor. Today, various studies have been carried out and new structures have been developed, especially to improve the production of stemmed glass glasses. One of these studies is the invention that is the subject of the patent application numbered TR2011 / 03330 and titled "Innovation in the Rotary Foot Pulling Mechanism for the Production of Footed Glasses". Thanks to this invention, it will be possible to produce one-piece footed glasses in 'Press-Blowing' machines that produce glass cups. With the 'Rotary Foot Pulling Mechanism' that will be added to the production arms of the 'Press-Blow' machine, footed glass production will be achieved more economically and more efficiently.

[0007] In the existing systems used today, the neck mould is rotated by air or torque motor. This motor is positioned on the side of the mechanism and the movement is transmitted via gears and drives the pulley. In the current application, there are problems such as high energy cost, difficulty in maintenance and repair, production stops due to glass jams and decrease in product quality due to not having full control over the motor.

[0008] As a result, the requirement for a neck mould rotating mechanism which eliminates the abovementioned problems and the insufficiency of the current solutions makes it necessary to make a development in the relevant technical field.

[0009] Brief Description of the Invention

[0010] The present invention relates to a mechanism for rotating the upper jaw holding and carrying apparatus called neck mould, which is used in the production of glass cups, around its centre axis, and which provides more reliable and efficient results compared to existing methods, which fulfils the above-mentioned requirements, eliminates all disadvantages and introduces some additional advantages.

[0011] Based on the state of the art, the object of the present invention is to eliminate the need for gears, bearings, cantilever covers, reducers and similar parts used in the existing systems for the hollow shift motor (hollow shaft motor) added to the neck mould rotating mechanism and the related problems such as high energy costs, maintenance and repair difficulties, manufacturing stops due to glass jams and decrease in product quality due to not having full control over the motor.

[0012] The object of the present invention is to enable the hollow shaft motor to be connected directly to the inner ring of the motor without any motion transmitting parts such as a gear, bearing, console cover, reducer and similar parts, thanks to its bagel-shaped geometry. A further object of the present invention is to save the cost of air consumption in the event that the neck mould rotating mechanism is used as an alternative to air motorised systems.

[0013] Another object of the present invention is to eliminate the gaps (reducer backlash, inter-gear backlash and the like) caused by these parts and to directly increase the quality of the end product by not using intermediate parts.

[0030] In this detailed description, a neck mould rotating mechanism (10) of the present invention for rotating the upper jaw holding and carrying apparatus called neck mould (11 ), which is used in the production of glass cups, around its centre axis, and which provides more reliable and efficient results compared to existing methods, is explained only as an example for a better understanding of the subject and in a way that does not create any limiting effect.

[0031] The neck mould rotating mechanism (10), which is the subject of the invention, was developed to be used in the glass (20) production process and is connected to the press blowing machine arm (30) shown in Figure-1. In the mentioned press blowing machine arm (30), the neck mould (11) holds the glass (20) from the upper jaw part and the sagging process is performed on the glass (20). Said neck mould (11) rotates the glass (20) around its central axis. The special feature of the neck mould rotating mechanism (10) shown in Figure 2 is the addition of a hollow shaft motor. Thanks to the mentioned hollow shaft motor, rotational movement is given to the neck mould (11) without using gears, bearings, console covers, reducers and similar parts used in existing systems. Hollow shaft motor is a torus shaped electric motor comprises a motor inner ring in the hollow center (13) and a motor outer ring (14). Depending on the application, may prefer the motor inner ring (13) may be fixed, the motor outer ring (14) rotating, or the motor outer ring (14) fixed and the motor inner ring (13) rotating. In the neck mould rotating mechanism (10) of the present invention, a hollow shaft motor containing a fixed motor outer ring (14) and a rotating motor inner ring (13) is preferably used.

[0032] The neck mould rotating mechanism (10) shown in Figure-3 comprises the neck mould (11), which is the upper jaw holding and carrying mould-apparatus of the glass (20) products; the neck mould console (12) carrying the hollow shaft motor; the connecting element (15) connecting the neck mould (11) and the hollow shaft motor. Motor inner ring (13) forming the hollow shaft motor ensures the rotation of the neck mould (11) and therefore the semi-finished glass (20) carried by the neck mould (11). Said fixed motor outer ring (14) is the part of the hollow shaft motor that is fixed to the neck mould console (12).

[0033] When the press blowing machine starts to work, a signal is sent to the hollow shaft motor connected to the press blowing machine arm (30) to ensure that the glass (20) rotates in the mould and the cape is formed. This motor starts to rotate the glass (20) held from above by the neck mould (11) shown in Figure-4. Neck mould (11) and hollow shaft motor are directly connected to each other; in this way, the connection components used in existing systems and the malfunctions, costs and maintenance processes resulting from them are eliminated. Additionally, the stability and control ability of the system has increased. Thanks to the full control of the hollow shaft motor, it was possible to produce the desired quality. In the mentioned neck mould rotating mechanism (10), the rotational movement of the neck mould (11 ) is provided by directly connecting the neck mould (11) and the hollow shaft motor without the use of drive organs (gears, reducers and the like). The hollow shaft motor carries the neck mould console (12) and is connected to the neck mould (11) with the help of the connection element (15). During manufacturing, it starts working by receiving a signal at the time when the motor should rotate. As the hollow shaft motor rotates, the neck mould (11) and glass (20) also rotate, thus the motor fulfils its duty.
