Description

[Background Technology]

[0001] Glass tubes are commonly used to manufacture pharmaceutical packaging, such as syringes and cartridges. These syringes or cartridges are used, for example, in auto-injectors or wearable delivery devices, such as insulin pens or wearable insulin delivery devices. In these auto-injectors or wearable delivery devices, a dose of the pharmaceutical composition is administered by moving a plunger a specific distance within the syringe or cartridge. To minimize the size of these auto-injectors or wearable delivery devices, a practical means is to minimize the size of the syringe or cartridge attached thereto. However, this leads to a reduction in the number of doses, because reducing the size of the syringe or cartridge also reduces its volume. However, since changing wearable delivery devices is inconvenient and multiple doses that can be administered with a single auto-injector are advantageous, there is a need to extend the lifespan of wearable delivery devices or increase the number of doses that can be administered with a single auto-injector. To achieve this, one method is to increase the concentration of the medicinal compound in the syringe or cartridge, thereby reducing the volume of the pharmaceutical composition administered in a single dose. However, to significantly increase the concentration of the medicinal compound in the pharmaceutical composition, one or more geometric parameters of the entire syringe or cartridge, such as the inner diameter, must be known precisely, i.e., in the μm range, and must not vary along the cylindrical portion of the syringe or cartridge, nor differ significantly between different syringes or cartridges fitted when they are replaced. This is especially true since the volume administered is controlled solely by the movement of the plunger. The cylindrical portion of a glass pharmaceutical package is defined by a portion of the glass tubing used in the manufacture of the pharmaceutical package. These glass tubing is generally manufactured by the Danner or Bellows process, in which glass tubing is produced continuously and then cut to length.The inventors recognize that it is advantageous and only possible to identify one or more geometric parameters measured continuously in the μm range over the entire glass tube before the tube is cut to length, because, At this point, the glass tube is lying perfectly flat for measurement. • The surface is flawless (flame polished), and • Minimal contact with other materials • Minimizing exposure time to the environment, • Not cut to length This is because, as a result, the defects are minimal.

[0002] Furthermore, the measuring equipment required to inspect the tube in the μm range is very bulky and can only measure a very narrow area along the tube, making it impossible to position the measuring equipment around the glass tube to measure the entire cut tube. Moreover, the cut tubes are transported perpendicular to their axis of rotation, enabling a densely packed production line and allowing for further processing steps at the ends of the cut tubes, namely flame polishing or end sealing. Thus, the placement of the measuring equipment hinders further processing steps. The difficulty in measuring one or more geometric parameters, such as the inner diameter, before cutting a continuous glass tube to length is that the tube can only be measured a few seconds after it has reached a temperature below the glass transition temperature, i.e., the point at which the molten glass solidifies. Furthermore, due to harsh and fluctuating measurement conditions (temperature, airflow, heat-induced refraction anomalies), the measurements are not stable over long periods. Therefore, the inventors recognized that in order to overcome this drawback and enable the continuous and reliable measurement of one or more geometric parameters, such as the inner diameter, in the μm range, the measuring system, which is mounted between the point where the molten glass solidifies and the drawing device commonly used in the Danner or Bellow method, must be continuously calibrated. [Overview of the Initiative] [Problems that the invention aims to solve]

[0003] Therefore, the object of the present invention is to provide an improved method or system that can continuously and reliably inspect one or more geometric parameters, preferably the inner diameter, of an elongated glass member, preferably a glass tube, down to the μm range.

[0004] Furthermore, an object of the present invention is to provide a bundle containing cut elongated glass members having improved quality, that is, at least one geometric parameter, such as an inner diameter, being within a specific range and reliably and accurately measured, for example, in the μm range. [Means for solving the problem]

[0005] The challenges and other challenges relate to a method for obtaining a cut, elongated glass component, and the following steps: • The stage of supplying a continuous, elongated glass component, - A step of continuously measuring one or more geometric parameters of the continuous elongated glass member to obtain one or more consecutive geometric parameters. The step of cutting the aforementioned continuous elongated glass member to obtain the cut elongated glass member, The steps include: measuring one or more geometric parameters at one or more points along the axis of rotation of the cut elongated glass member to obtain one or more individual geometric parameters, and - A step of connecting one or more of the continuous geometric parameters with one or more of the individual geometric parameters. The problem is solved by the method which preferably includes in this order.

[0006] An apparatus for continuously measuring one or more geometric parameters of a continuous elongated glass member, i.e., the first measuring apparatus, is not particularly limited. The apparatus for continuously measuring one or more geometric parameters of a continuous elongated glass member, i.e., the first measuring apparatus, is preferably a measuring apparatus as described in the European Patent Application No. 20195758.6 (EP20195758.6), which is incorporated by reference herein. An apparatus for measuring one or more geometric parameters at one or more points along the axis of rotation of a cut elongated glass member, i.e., the second measuring apparatus, is not particularly limited. The apparatus for measuring one or more geometric parameters at one or more points along the axis of rotation of a cut elongated glass member, i.e., the second measuring apparatus, is preferably a measuring apparatus as described in European Patent Application Publication No. 3848701 (EP3848701 (A1)) (European Patent Application No. EP20150706.8), which is incorporated by reference herein.

[0007] In particular, by linking one or more continuous geometric parameters with one or more individual geometric parameters, continuous measurements can be continuously adjusted inline. Therefore, measurement quality is improved, and one or more geometric parameters can be reliably measured within the μm range. As a result, a cut, elongated glass component with improved quality can be obtained. Furthermore, since one or more geometric parameters are measured twice at a single point, the reliability of the measurement is further improved.

[0008] In a preferred embodiment of the present invention, the method involves the following steps: • The stage of supplying a continuous, elongated glass component, - A step of continuously measuring one or more geometric parameters of the continuous elongated glass member to obtain one or more consecutive geometric parameters. The step of cutting the aforementioned continuous elongated glass member to obtain the cut elongated glass member, • A step of sorting and removing cut, elongated glass components that exhibit one or more consecutive geometric parameters that are not within a predetermined range. The step of measuring one or more geometric parameters at one or more points along the axis of rotation of the cut elongated glass member to obtain one or more individual geometric parameters, - A step of linking one or more of the continuous geometric parameters with one or more of the individual geometric parameters, preferably controlling whether the cut elongated glass members having one or more continuous geometric parameters that are not within a predetermined range have been sorted out and removed, and Preferably, a step of sorting and removing cut elongated glass members that exhibit one or more consecutive geometric parameters and / or one or more individual geometric parameters that are not within a predetermined range. Preferably, these should be included in this order.

[0009] Therefore, the reliability of the measurements can be improved, and consequently, the quality of the resulting cut, elongated glass components can be improved.

[0010] In a preferred embodiment, the supply of a continuous elongated glass member is carried out in the following steps: • A step of supplying a continuous, elongated glass member by the Danner method or the Bellow method, preferably by the Danner method, and - The step of continuously drawing out the aforementioned elongated glass members using a drawing device. Includes, Preferably, the continuous elongated glass member is continuously drawn out, while the continuous elongated glass member is continuously measured, and / or Preferably, the speed of the drawing device is used to connect the one or more consecutive geometric parameters with the one or more individual geometric parameters, and / or The process of cutting the aforementioned continuous elongated glass member to obtain the cut elongated glass member is carried out by a cutting device. Preferably, the point of cutting in the cutting stage is used to link one or more consecutive geometric parameters with one or more individual geometric parameters.

[0011] Therefore, the reliability of the measurement can be improved.

[0012] In a preferred embodiment, the method further steps: The step of identifying the cut elongated glass member, preferably in a later manufacturing stage or final product, using the one or more consecutive geometric parameters and / or the one or more individual geometric parameters, and / or The steps of bundling the cut elongated glass members together to form a bundle containing the cut elongated glass members, and / or The step of manufacturing one or more, preferably five or more, pharmaceutical packages from the cut, elongated glass members, and preferably bundling the pharmaceutical packages to form a bundle of pharmaceutical packages. Includes.

[0013] Techniques for forming pharmaceutical packages from elongated glass components are well known in the prior art, for example, in German Patent No. 102005038764 (DE102005038764 B3) and German Patent No. 102006034878 (DE102006034878 B3).

[0014] A further aspect of the present invention is a system for carrying out a method preferably described herein for obtaining a cut, elongated glass member. • A feeding device configured for supplying a continuous, elongated glass component. A first measuring device configured to continuously measure one or more geometric parameters of the aforementioned continuous elongated glass member in order to obtain one or more consecutive geometric parameters, A cutting device configured to cut the aforementioned continuous elongated glass member in order to obtain the cut elongated glass member. A second measuring device configured to measure one or more geometric parameters at one or more points along the rotation axis of the cut elongated glass member to obtain one or more individual geometric parameters, and A computer unit configured to link one or more of the continuous geometric parameters with one or more of the individual geometric parameters. The system includes the above.

[0015] A (preferred) embodiment of the present invention is a system, preferably according to any embodiment described herein, for carrying out a method preferably described herein for obtaining a cut elongated glass member, • A feeding device configured for supplying a continuous, elongated glass component. A first measuring device configured to continuously measure one or more geometric parameters of the aforementioned continuous elongated glass member in order to obtain one or more consecutive geometric parameters, A cutting device configured to cut the aforementioned continuous elongated glass member in order to obtain the cut elongated glass member. A sorting device configured to sort and remove cut, elongated glass pieces exhibiting one or more consecutive geometric parameters that are not within a predetermined range. A second measuring device configured to measure one or more geometric parameters at one or more points along the rotation axis of the cut elongated glass member in order to obtain one or more individual geometric parameters, - A computer unit configured to control whether the cut elongated glass members having one or more consecutive geometric parameters that are not within a predetermined range have been sorted out, in order to link one or more of the continuous geometric parameters with one or more of the individual geometric parameters, and Preferably, a further sorting device for sorting and removing cut elongated glass pieces that exhibit one or more consecutive geometric parameters and / or one or more individual geometric parameters that are not within a predetermined range. The system including the above is provided.

[0016] Therefore, the reliability of the measurements can be improved, and consequently, the quality of the resulting cut, elongated glass components can be improved.

[0017] In a preferred embodiment, the system further includes a pull-out device, and the computer unit uses the speed of the pull-out device and / or the cutting point in the cutting stage to link one or more continuous geometric parameters with one or more individual geometric parameters. Thus, the reliability of the measurements can be further improved.

[0018] In a preferred embodiment, continuous elongated glass members are supplied by the Danner or Bellows method, preferably by the Danner method, and the continuous elongated glass members are preferably drawn continuously, preferably non-contact, by a drawing device / the drawing device through a first measuring device, while one or more continuous geometric parameters are measured. Thus, continuous elongated glass members, preferably glass tubes, that already have high quality with respect to one or more geometric parameters, particularly inner diameter, can be supplied, and the amount of cut elongated glass members that must be sorted and removed to obtain a bundle containing cut elongated glass members that have high quality with respect to one or more geometric parameters, particularly inner diameter, is reduced. Furthermore, the overall quality of the cut elongated glass members can be further improved as the quality of all relevant one or more geometric parameters produced by the modern Danner or Bellows method is improved. In particular, the modern Danner method for supplying continuous glass that partially meets the high quality requirements described below is well known to those skilled in the art, and is described, for example, in the "Schott Guide to Glass" (ISBN-10: 9401042306, Springer). However, even when using methods for producing high-quality continuous elongated glass components, it is not possible to guarantee that the quality of one or more specific geometric parameters, preferably inner diameter, will always be stable for several reasons, such as unavoidable process variations, impurities in the starting materials, weather fluctuations, and changes in ambient temperature, and is particularly unstable in the μm range.

[0019] The method for cutting a continuous elongated glass member is not particularly limited. Preferably, to cut a continuous elongated glass member and obtain the cut elongated glass member, the continuous elongated glass member is scribbled to make fine scratches, and then the continuous elongated glass member is cut by breaking it at the fine scratches, thereby obtaining the cut elongated glass member. Even if particles are always generated, this method is very efficient and has a low defect rate due to cutting defects.

[0020] One or more points along the axis of rotation of one or more elongated glass members are not particularly limited. Preferably, the cut elongated glass members include a first end, a second end, and a cylindrical portion, and / or one or more points along the axis of rotation of the cut elongated glass members are the center of the first end, second end, and / or cylindrical portion of each cut elongated glass member, preferably the center. The measurement of one or more geometric parameters at the first end and / or second end may be affected by the cutting method (particles), the end formation method (condensation), and the transport (scratching). Therefore, measurement at the center is particularly preferred.

[0021] The time between measurements of one or more geometric parameters is not particularly limited. Preferably, the time between continuous measurements and measurements at one or more points along the axis of rotation is 1 year or less, preferably 30 days or less, more preferably 7 days or less, preferably 1 day or less, more preferably 12 hours or less, more preferably 6 hours or less, more preferably 1 hour or less, more preferably 30 minutes or less, more preferably 15 minutes or less, more preferably 5 minutes or less, and more preferably 2 minutes or less. If the time between measurements is too long, dust may accumulate in or on the circular elongated glass member, affecting the measurements, especially the (second) measurements at one or more points along the axis of rotation. In particular, if the time is 1 hour or less, preferably 30 minutes or less, more preferably 15 minutes or less, and more preferably 5 minutes or less, the reliability of the measurements can be improved. In a preferred embodiment, the time between continuous measurements and measurements at one or more points along the axis of rotation is 5 seconds or more, preferably 10 seconds or more, more preferably 30 seconds or more, and more preferably 60 seconds or more.

[0022] The types of geometric parameters are not particularly limited. They may be any dimensions and / or angles of a circular, elongated glass member. Preferably, one or more geometric parameters include an inner diameter I, an outer diameter, ellipticity and / or wall thickness, preferably an inner diameter I, an outer diameter, ellipticity and / or wall thickness, more preferably an inner diameter I, or more preferably an inner diameter I and / or One or more geometric parameters include two or more, preferably three or more, more preferably four or more, and more preferably five or more geometric parameters.

[0023] Selectively, or preferably, the one or more individual geometric parameters include an individual inner diameter, an individual outer diameter, an individual ellipticity and / or an individual wall thickness, preferably an individual inner diameter, an individual outer diameter, an individual ellipticity and / or an individual wall thickness, more preferably an individual inner diameter, more preferably an individual inner diameter, and / or The one or more continuous geometric parameters are the continuous inner diameter, the continuous outer diameter, the continuous ellipticity and / or the continuous wall thickness, more preferably the continuous inner diameter I 連続 Including, more preferably a continuous inner diameter I 連続 and / or The one or more individual geometric parameters are the central inner diameter, central outer diameter, central ellipticity and / or central wall thickness, preferably the central inner diameter I 中央 and / or The one or more geometric parameters obtained by continuous measurement and the one or more geometric parameters obtained by measurement at one or more points are the same, preferably the continuous inner diameter I 連続 , and individual inner diameters, more preferably the central inner diameter I 中央 That is the case.

[0024] In particular, the inner diameter can be determined with great accuracy in the μm range using the methods and / or systems described herein.

[0025] In a preferred embodiment, continuous measurements include measurements using an interferometer, and / or measurements at one or more points along the axis of rotation include measurements using an interferometer. Thus, the reliability of measurements of one or more individual geometric parameters can be improved.

[0026] The means for linking the aforementioned measurements are not particularly limited. However, the inventors have surprisingly found that linking one or more continuous geometric parameters with one or more individual geometric parameters is possible in one or more of the following ways: • Calibrating continuous measurements based on measurements at one or more points along the axis of rotation, preferably continuously, and / or • Adapting, preferably continuously adapting, one or more consecutive geometric parameters based on one or more individual geometric parameters, and / or • Calibrating, preferably continuously calibrating, measurements at one or more points along the axis of rotation based on continuous measurements, and / or • Adapting, preferably sequentially, one or more individual geometric parameters based on one or more consecutive geometric parameters, and / or • Comparing one or more consecutive geometric parameters to one or more individual geometric parameters, and / or assigning them to one or more individual geometric parameters, and / or • Comparing one or more individual geometric parameters to one or more consecutive geometric parameters, and / or assigning them to one or more consecutive geometric parameters, and / or • Link one or more parameters to obtain information about the quality of a cut, elongated glass component with respect to one or more geometric parameters. We realized that in this case, the measurement could be significantly improved.

[0027] In a preferred embodiment, one or more continuous geometric parameters and one or more individual geometric parameters are measured and associated as described herein, so as to obtain information about the quality of the cut elongated glass member regarding one or more geometric parameters.

[0028] In particular, continuously calibrating and / or adapting the values or measurements, preferably calibrating, that is, every hour or less, preferably every minute or less, preferably every 40 seconds or less, and / or, preferably or, every approximately 5 times or less the length of the circular portion of the circular elongated glass member, preferably every 2 times or less, and calibrating and / or adapting, preferably calibrating, can significantly improve the reliability of the measurement. In a preferred embodiment, by associating one or more continuous geometric parameters with one or more individual geometric parameters, one or more measurement points of the one or more individual geometric parameters are always associated with each respective measurement point of the one or more continuous geometric parameters, that is, the positions where the one or more geometric parameters are measured are always the same. Therefore, the measurement can be significantly improved.

[0029] Another aspect of the present invention is a bundle comprising five or more cut elongated glass members, each cut elongated glass member comprising a) a first end, b) a cylindrical portion, and c) a second end and satisfying one or more of the following equations: i) (I 中央 (max) - I 中央 (min)) / I 中央 (avg) ≤ 4.0×10 -2 [μm / μm], and / or ii) (I 連続 (max) - I 連続 (min)) / I 中央 (avg) ≤ 4.0×10 -2 [μm / μm] wherein, in the above equations, I 中央(Maximum) is the inner diameter of the largest central part of the cylindrical portion of all the cut elongated glass members in the bundle. I 中央 (Minimum) is the smallest central inner diameter of the cylindrical portion of all the cut elongated glass members in the bundle. I 中央 (Average) is the average of the central inner diameters of the cylindrical portions of all the cut, elongated glass members in the bundle. I 連続 (Maximum) is the maximum continuous inner diameter of the cylindrical portion of any one cut elongated glass member in the bundle, and I 連続 (Minimum) is the smallest continuous inner diameter of the cylindrical portion of one of the cut elongated glass members in the bundle. This is the aforementioned bundle.

[0030] If formula i) and / or ii) are satisfied, a bundle of circular, elongated glass members having improved quality is provided. If both formula i) and ii) are satisfied (which is preferable), the quality of the bundle can be further improved.

[0031] The lower limit of parameter i) is not particularly limited. However, if the value is too low, the effort required to reach this value will outweigh the benefits. Therefore, preferably the following equation is satisfied: iii) a ≤ (I 中央 (Max)-I 中央 (minimum) / I 中央 (average) In the above formula, a [μm / μm] is 1.0 × 10 -6 Preferably 1.0 × 10 -5 , comfortably 1.0 × 10 -4 , comfortably 1.0 × 10 -3 , comfortably 1.0 × 10 -2 That is the case.

[0033] The lower limit of parameter ii) is not particularly limited. However, if the value is too low, the effort required to reach this value will outweigh the benefits. Therefore, preferably the following equation is satisfied: v) c≦(I 連続 (Max)-I 連続 (minimum) / I 中央 (average) In the above formula, c[μm / μm] is 1.0×10 -6 Preferably 1.0 × 10 -5 , comfortably 1.0 × 10 -4 , comfortably 1.0 × 10 -3 , comfortably 1.0 × 10 -2 That is the case.

Preferably (I 中央 (Max)-I 中央(Minimum) is 200 μm or less, preferably 150 μm or less, more preferably 120 μm or less, more preferably 110 μm or less, more preferably 100 μm or less, more preferably 90 μm or less, more preferably 80 μm or less, more preferably 70 μm or less, more preferably 65 μm or less, more preferably 60 μm or less, more preferably 55 μm or less, more preferably 50 μm or less, more preferably 45 μm or less, more preferably 40 μm or less, more preferably 35 μm or less, more preferably 30 μm or less, more preferably 25 μm or less, more preferably 20 μm or less, more preferably 15 μm or less, more preferably 10 μm or less, more preferably 5 μm or less. Therefore, the quality of the bundle can be further improved. In particular, values of 50 μm or less, preferably 45 μm or less, more preferably 40 μm or less, more preferably 35 μm or less, more preferably 30 μm or less, more preferably 25 μm or less, more preferably 20 μm or less, more preferably 15 μm or less, more preferably 10 μm or less, more preferably 5 μm or less are preferred for improving the suitability of the bundle for manufacturing syringes and cartridges.

[0037] (I 中央 (Maximum) - I 中央 (Average) and (I 中央 (Average) - I 中央 (Minimum) are not particularly limited. Preferably, one or more of the following formulas are satisfied: vii) (I 中央 (Maximum) - I 中央 (Average) ≤ e In the above formula, e is 100 μm, preferably 80 μm, more preferably 70 μm, more preferably 60 μm, more preferably 50 μm, more preferably 40 μm, more preferably 30 μm, more preferably 20 μm, more preferably 15 μm, more preferably 10 μm, more preferably 5 μm, more preferably 2 μm, and / or, preferably and viii) (I 中央 (Average) - I 中央 (Minimum) ≤ f; In the above formula, f is 100 μm, preferably 80 μm, more preferably 70 μm, more preferably 60 μm, more preferably 50 μm, more preferably 40 μm, more preferably 30 μm, more preferably 20 μm, more preferably 15 μm, more preferably 10 μm, more preferably 5 μm, more preferably 2 μm.

[0038] Therefore, the quality of the bundle can be further improved. The respective amounts and frequencies of continuous measurements are not particularly limited. Preferably, I 連続 (maximum) and / or I 連続 (minimum), and / or one or more geometric parameters are measured every 20 cm or less, preferably 0.01 cm to 10 cm, more preferably 0.05 to 2 cm, more preferably 0.1 to 1 cm, more preferably every 1.0 mm along the rotation axis of the elongated glass member and / or tube. Therefore, the quality of the bundle and the reliability of the measurement can be further improved.

[0039] According to the present invention, the bundle includes five or more cut elongated glass members. Preferably, the bundle includes 5 or more, preferably 10 or more, more preferably 25 or more, more preferably 25 or more, more preferably 35 or more, more preferably 50 or more, more preferably 60 or more, more preferably 75 or more, more preferably 90 or more, more preferably 100 or more cut elongated glass members, and / or preferably and, 1000 or less, preferably 800 or less, more preferably 700 or less, more preferably 600 or less, more preferably 500 or less, more preferably 400 or less, more preferably 300 or less, more preferably 200 or less, more preferably 150 or less, more preferably 120 or less, more preferably 100 or less cut elongated glass members, preferably shown. The more cut elongated glass members there are in the bundle, especially when the bundle includes 50 or more, preferably 75 or more, more preferably 100 or more cut elongated glass members, it becomes more difficult for each cut elongated glass member to satisfy the parameters described in the present application.

[0040] In a (preferred) embodiment of the present invention, the cut elongated glass members are inspected by a method and / or system according to any embodiment described herein. Thus, bundles with improved quality are obtained.

[0041] In a preferred embodiment, the continuous inner diameter and / or preferably individual inner diameters of the cut elongated glass members can be obtained, preferably, by methods and / or systems according to any embodiment described herein. Thus, the geometric parameters can be measured reliably, and the quality of the bundle can be improved.

[0042] When one or more geometric parameters are internal diameters, these internal diameters can be determined in various ways. Preferably, internal diameter I and / or internal diameter I 中央 The (average) is the average, maximum and / or minimum, preferably the mean, of two or more measurements of the inner diameter, preferably 2 to 20, more preferably 2, 3, 4, 5 or 6, distributed perpendicularly or equally to each other at each point along the axis of rotation of the elongated glass member, and / or I 中央 (Maximum) and I 連続 (Maximum) is the average, maximum and / or minimum of two or more measurements of the inner diameter, preferably 2 to 20, more preferably 2, 3, 4, 5 or 6, preferably distributed perpendicularly or equally to each other at each point along the axis of rotation of the elongated glass member, and preferably the maximum and / or I 中央 (Minimum) and / or I 連続 The (minimum) is the average, maximum, and / or minimum, preferably the minimum, of two or more inner diameters, preferably 2 to 20, more preferably 2, 3, 4, 5, or 6 measurements, preferably perpendicular to each other or equally distributed, at each point along the axis of rotation of the elongated glass member.

[0112] In the following description of embodiments, the same reference numerals indicate the same elements. [Modes for carrying out the invention]

[0113] Figure 1 shows a schematic diagram of system (1) according to an embodiment of the present invention. Initially, molten glass (100) flows over a Danner mandrel (102) mounted on a motor (101). During this time, the motor (101) continuously rotates the Danner mandrel (102). The motor (101) and the Danner mandrel (102) are tilted so that the molten glass (100) reaches the lower end of the Danner mandrel (102), where a tube of molten glass is formed. The tube of molten glass (100) cools at a specific position (103), and the tube of molten glass solidifies, forming a glass tube (10), that is, a continuous elongated glass member (10). The solid glass tube (10) is pulled out by a pulling device (23). At a position between the point where the molten glass solidifies (103) and the drawing device (23), one or more geometric parameters, such as the inner diameter, are continuously measured by a first measuring device (21), while the glass tube (10) is continuously drawn by the drawing device (23). After the tube has passed through the drawing device (23), it is separated, for example, cut to length by a cutting device (24) to obtain cut glass tubes (11), i.e., cut elongated glass members (11). The system 1 includes a sorting device (25) that sorts and removes cut glass tubes (11) whose one or more geometric parameters are not within a predetermined range. Subsequently, one or more geometric parameters of the cut glass tubes (11) are measured by a second measuring device (22). A computer unit (20) is connected to the first measuring device (21), the second measuring device (22), the drawing device (23), and the cutting device (24) to continuously collect data from them. Furthermore, the computer unit can continuously calibrate the first and second measuring devices and control whether the cut elongated glass members (11) having one or more geometric parameters outside the predetermined range have been sorted and removed by the sorting device (25). Finally, a further sorting device (26) sorts and removes the cut elongated glass members (11) having one or more geometric parameters outside the predetermined range, and then the high-quality cut elongated glass members (11) are packed into bundles (12).
