Description

Technical Field

[0001] The present invention relates to a specific inspection device for ensuring the quality of a cylindrical body and a specific bundle of cylindrical bodies with improved flatness.

[0002] The present invention relates to an inspection device for a cylindrical body, the inspection device comprising: i) a conveying device; ii) a rotating device; and iii) a measuring device; wherein the conveying device is configured to move the cylindrical body relative to the measuring device; wherein the rotating device and the conveying device are configured to rotate the cylindrical body when the cylindrical body moves relative to the measuring device; and wherein the measuring device is configured to measure the cylindrical body when the cylindrical body moves relative to the measuring device and when the cylindrical body rotates. In addition, a specific bundle of cylindrical bodies with improved flatness is also disclosed herein, and the specific bundle can be obtained by using the above specific inspection device. Background Art

[0003] The demand for high-quality cylindrical bodies is increasing. This is because cylindrical bodies with insufficient quality can cause a high scrap rate and lead to machine failures. For example, particles outside the dimensional tolerance generated by damaged or broken cylindrical bodies can contaminate the machine. Moreover, due to the increasing economic competition in the field of pharmaceutical products such as vials, cartridges, syringes or ampoules, efficient production has become even more important. And efficient production is only possible when the quality of the cylindrical bodies that can be used as semi-finished products of these pharmaceutical products is high. Therefore, the degree of curvature of the cylindrical body is especially an important quality measure. If the degree of curvature of the cylindrical body is large, the cylindrical body (such as a glass tube) may be damaged or broken when it is further processed into pharmaceutical products such as vials, cartridges, syringes or ampoules.

[0004] In order to obtain high-quality cylindrical bodies, a large number of measures need to be taken. For example, the manufacturing process of the cylindrical body can be improved, such as the Danner process or the Vello process. However, these improvements have certain limitations and usually result in costs exceeding the final benefits. In addition, there are certain quality standards, but not all cylindrical bodies can reliably meet this standard. Usually, the produced cylindrical bodies can be packed into bundles without any inspection. Even if the overall average quality is high, it has the following disadvantages: if the quality of one of the cylindrical bodies is low, this will only become obvious at the processor site and may lead to machine failures and thus additional costs.

[0005] Another measure for improving the overall quality of the cylindrical body is to produce cylindrical bodies with a certain average quality and to improve the overall quality by picking out cylindrical bodies with a quality below a specific value. Therefore, in order to better evaluate the cylindrical body, it is particularly important to evaluate the entire circumference of the cylindrical body. For evaluation in a production line, this evaluation needs to be fast, efficient and reliable. Therefore, if the cylindrical body rotates about its own axis, the entire circumference can be evaluated quickly, efficiently and reliably. This in turn can only be achieved by means of the device continuously rotating the cylindrical body during measurement, or the device rotating the cylindrical body repeatedly at specific angles so as to measure it at each angle. If the cylindrical body is rotated repeatedly, it is usually necessary to remove the cylindrical body from the conveying device, insert it into the testing equipment, conduct the test, and then insert it back into the conveying device again. This process is very time-consuming. Summary of the Invention

[0006] Therefore, an object of the present invention is to provide a testing device that overcomes the above-mentioned drawbacks and is used for detecting the entire circumference of a cylindrical body, in particular for detecting the curvature of a cylindrical body. Another object of the present invention is to provide a testing device for a cylindrical body that can test the cylindrical body without removing it from the conveying device. Another object of the present invention is to provide a testing device for a cylindrical body that can measure the cylindrical body faster, more efficiently and more reliably.

[0007] Another object of the present invention is to provide a cluster pack of cylindrical bodies that enables subsequent processes to be improved, preferably enabling subsequent processes to be flawless.

[0008] The inventors have surprisingly found that this object can be achieved by a testing device for a cylindrical body, the testing device comprising: i) a conveying device; ii) a rotating device; and iii) a measuring device; wherein the conveying device is configured to move the cylindrical body relative to the measuring device; wherein the rotating device and the conveying device are configured to rotate the cylindrical body when the cylindrical body moves relative to the measuring device; and wherein the measuring device is configured to measure the cylindrical body when the cylindrical body moves relative to the measuring device and when the cylindrical body rotates.

[0009] In this text, a cylindrical body is a body having at least one hollow or filled cylindrical portion that is long enough and has a suitable outer diameter such that it can be measured in a detection device. The cylindrical portion defines a rotational axis. Preferably, the cylindrical body is composed of a polymer or glass, more preferably composed of a cycloolefin copolymer (COC), a cycloolefin polymer (COP), a silicate glass, or a borosilicate glass. Preferably, the cylindrical body is selected from the group consisting of a tubular member, a conduit, a vial, an ampoule, a syringe, and a cartridge that can be sealed on one or both sides, and the cylindrical body is preferably a tubular member or a vial that can be sealed on one or both sides, and more preferably a tubular member that can be sealed on one or both sides, and even more preferably a tubular member sealed on both sides.

[0010] There are no specific limitations on the length and outer diameter of the cylindrical portion. However, if the length of the cylindrical portion is too short, the ratio of the plane of the cylindrical portion in contact with the detection device to the plane not in contact with the detection device during the detection process becomes larger. If the length of the cylindrical portion is too long, it will hinder the manipulation of the cylindrical body due to, for example, bending, and thus reduce the accuracy of the detection. Therefore, the preferred length of the cylindrical portion of the cylindrical body is above 1 cm and below 1000 cm, preferably above 20 cm and below 400 cm, more preferably above 60 cm and below 300 cm, more preferably above 100 cm and below 200 cm, and most preferably above 120 cm and below 180 cm; and / or the outer diameter of the cylindrical portion of the cylindrical body is above 2 mm and below 100 mm, more preferably above 4 mm and below 50 mm, more preferably above 6 mm and below 35 mm, more preferably above 8 mm and below 25 mm, and most preferably above 10 mm and below 20 mm. Preferably, the detection device includes the cylindrical body.

[0011] In this text, any term in the singular form should be understood to also include the plural, and any term in the plural form should also be understood to include the singular. Specifically, all the definitions and preferred embodiments of a single cylindrical body in this text also apply to multiple cylindrical bodies, such as more than 5 cylindrical bodies. In addition, unless otherwise stated, all the definitions and preferred embodiments of the detection device also apply to the cluster pack, and vice versa.

[0012] In this text, the plane is the plane of the device, and this plane should be in contact with the cylindrical body. The plane of the device itself can have any shape that can be circular or flat, such as a cylindrical shape or a cube shape. Regardless of the shape of the plane, what is important in this text for determining parameters (such as the calculation of angles or contact points) is the plane of the device that should be in contact with the cylindrical body when the cylindrical body is located in the detection device. In this text, "flat" means that for a plane, the measured part thereof is substantially free of curvature, preferably completely free of curvature.

[0013] In this text, a cluster pack is a trading unit, a loading unit, or a packaging unit for distributing cylindrical bodies. For example, usually but not necessarily, products of the same type are combined into a cluster pack when retail ordering or logistics packaging. According to the present invention, the cylindrical bodies in the cluster pack can be separated by spacers (such as plastic sheets or paper sheets) so that they do not contact each other during transportation. Usually but not necessarily, the cluster pack is at least partially covered with a plastic foil. Preferably, a cluster pack includes 5 to 5000, preferably 10 to 1000, more preferably 25 to 500, more preferably 50 to 300, and most preferably 75 to 250 cylindrical bodies. An example of a cluster pack is that of Schott AG For economic considerations, the cluster pack preferably includes 25 to 500, more preferably 50 to 300, and most preferably 75 to 250 cylindrical bodies, which are at least partially covered with a plastic foil, and wherein the cylindrical bodies are in direct contact with each other within the cluster pack. Preferably, the length of the cylindrical part of the cylindrical bodies in the cluster pack is more than 1000 mm.

[0014] In this text, relative movement is such a movement: in which the distance or angle (preferably the distance) between a specific object (such as a measuring device) and another specific object (such as a cylindrical body) changes. The individual rotation of a cylindrical body does not belong to relative movement because neither its distance nor its angle with another specific object changes.

[0015] In this text, "when the cylindrical body moves" or "when the cylindrical body rotates" means that the cylindrical body moves or rotates at least during this period.

[0016] The detection device for the cylindrical body includes a conveying device, a rotating device, and a measuring device. Minor modifications can be made to the detection device without departing from the scope of the present disclosure.

[0017] Conveyor device

[0018] The conveying device is configured to move the cylindrical body relative to the measuring device. The shape of the conveying device is not particularly limited. Generally, the conveying device includes a conveying plane and a feeding plane, wherein the conveying plane is configured to support the cylindrical body when the cylindrical body is not in contact with the rotating device, and wherein the feeding plane is configured to push the cylindrical body forward. Specifically, the feeding plane is configured to push the cylindrical body forward when the cylindrical body is in contact with the rotating device. Preferably, the feeding plane is fixedly mounted on the conveying plane; preferably, the feeding plane is a rod fixedly mounted on the conveying plane; more preferably, the feeding plane is a rod fixedly mounted on the conveying plane and extending perpendicular to the conveying plane.

[0019] The materials of the conveying plane and the feeding plane are not particularly limited. Preferably, the materials are adjusted according to the friction characteristics of the materials to achieve the optimal rotation of the cylindrical body and minimize the wear of the materials on the cylindrical body. If the conveying plane is composed of a polymer, preferably an elastomer, most preferably silicone rubber, the wear during the conveyance of the cylindrical glass body can be minimized. In addition, if the material of the feeding plane is composed of a polymer, graphite or wood (preferably composed of graphite), the friction between the cylindrical body and the conveying device can be minimized, and the defects in the cylindrical body can also be reduced.

[0020] The detection device may include one or more conveying devices. For example, it may include 2, 3 or 4 conveying devices. Preferably, the detection device includes two conveying devices, wherein the conveying devices are arranged parallel to each other or change their distances within the detection device; more preferably, the detection device includes two conveying devices, wherein the two conveying devices are parallel to each other.

[0021] Generally, the speed of the conveying device is not limited. However, if the speed of the conveying device is below 1 m / s, preferably between 0.001 m / s and 1 m / s, preferably between 0.001 m / s and 0.5 m / s, more preferably between 0.005 m / s and 0.25 m / s, most preferably between about 0.01 m / s and 0.2 m / s, the detection of the cylindrical body can be both fast and very accurate.

[0022] Rotating device

[0023] Generally, the rotating device includes a rotating plane. The shape of the rotating device is not particularly limited and it can be cylindrical or cubic.

[0024] The material of the rotating plane is not specifically limited. However, if the rotating plane is made of a polymer, preferably an elastomer, and most preferably silicone rubber, the wear during the conveyance of the cylindrical body can be minimized, and the particle load on the cylindrical body can also be reduced.

[0025] In one embodiment, the rotating device includes a static rotating plane, that is, the rotating plane does not move relative to the measuring device when detecting the cylindrical body. This is beneficial for simplifying the device structure, thereby saving maintenance costs and time.

[0026] In another embodiment, the rotating device includes a moving rotating plane, wherein the moving rotating plane moves relative to the measuring device and the conveying device. More preferably, the moving rotating plane is configured to move in the opposite direction relative to the conveying plane; more preferably, the moving rotating plane is configured to move at a speed of 0.001 km / h to 10 km / h, preferably at a speed of 0.001 m / s to 0.5 m / s, more preferably at a speed of 0.002 m / s to 0.3 m / s, more preferably at a speed of 0.005 m / s to 0.25 m / s, and most preferably at a speed of 0.01 m / s to 0.2 m / s in the opposite direction relative to the conveying plane. Thereby, the body can be detected faster. Redundant detection of the entire circumference can be achieved by a high rotational speed relative to the conveying speed of the conveying device during detection. Such a high rotational speed can be achieved by providing a moving rotating plane, wherein the moving rotating plane is configured to move in the opposite direction relative to the conveying plane.

[0027] In one embodiment, the rotating device includes a rotating plane, wherein the rotating plane is a flat rotating plane. In another embodiment, the rotating plane is a non-flat rotating plane. Preferably, the rotating plane is a flat rotating plane.

[0028] Preferably, the width of the rotating plane is between 0.1 mm and 200 mm, preferably between 1 mm and 5 mm. If the width is too small, the frictional force required to rotate the cylindrical body is insufficient. On the contrary, if the width is too wide, the contact area of the rotating plane increases and the defects of the cylindrical body also increase.

[0029] Preferably, the length of the rotating plane is between 1 cm and 300 cm, preferably between 5 cm and 200 cm, and more preferably between 10 cm and 50 cm. If the rotating plane is too short, uniform measurement cannot be performed. On the contrary, if the rotating plane is too long, the contact flat area of the rotating plane increases and the defects of the cylindrical body also increase.

[0030] The detection device may include one or more rotating devices. For example, it may include 2, 3, or 4 rotating devices. In one embodiment, the rotating devices are arranged diagonally in the detection device. In another embodiment, the detection device includes two rotating devices, wherein the rotating devices are arranged parallel to each other or change their distance within the detection device; more preferably, the detection device includes two rotating devices, and the two rotating devices are parallel to each other.

[0031] Rotating device and conveyor device

[0032] The rotating device and the conveying device are configured to rotate the cylindrical body when the cylindrical body moves relative to the measuring device. Preferably, during the rotation of the cylindrical body, the cylindrical body does not contact the conveying plane of the conveying device. Thus, generally, the conveying device includes a conveying plane and a supply plane, and the rotating device includes a rotating plane. The rotation is achieved in such a way that during the rotation, the cylindrical body contacts the supply plane of the conveying device and the rotating plane of the rotating device, but does not contact the conveying plane of the conveying device.

[0033] Preferably, at least a part of the rotating plane is parallel to the conveying plane. Preferably, the supply plane and the rotating plane are perpendicular to each other. Preferably, the conveying device and the rotating device are configured to lift the cylindrical body when the cylindrical body moves relative to the measuring device and when the cylindrical body rotates. Thus, preferably, the conveying device and the rotating device have an inclined rotating plane, wherein the inclined rotating plane is configured to lift the cylindrical body when the cylindrical body moves relative to the measuring device and when the cylindrical body rotates. With the above configuration, the frictional force under the influence of gravity can be reduced and the generation of defects can also be prevented.

[0034] More preferably, at least a part of the rotating plane is parallel to the conveying plane, and the supply plane and the rotating plane are perpendicular to each other. The rotating plane is an inclined rotating plane, wherein the inclined rotating plane is configured to lift the cylindrical body when the cylindrical body moves relative to the measuring device and when the cylindrical body rotates.

[0035] Preferably, the conveying device and the rotating device do not contact each other. Thus, the two devices can be installed separately, thereby reducing the maintenance work of the detection device. Additionally, if the conveying device and the rotating device are not directly connected to each other, the contact area between the cylindrical body and the conveying device and the rotating device can be adjusted. Thereby, the generation of defects can be prevented.

[0036] The detection device may include one or more rotating devices and one or more conveying devices. In a preferred embodiment, the detection device includes more than two rotating devices and more than two conveying devices, wherein the rotating devices and the conveying devices are parallel to each other or change their distances within the detection device; more preferably, the detection device includes more than two, preferably two rotating devices, and includes more than two, preferably two conveying devices, wherein the rotating devices and the conveying devices are parallel to each other.

[0037] Measuring device

[0038] The measuring device is configured to measure the cylindrical body when the cylindrical body moves relative to the measuring device and when the cylindrical body rotates.

[0039] Generally, several parameters can be measured. The detection device may include one or more measuring devices so as to be able to detect one or more parameters simultaneously, or to be able to determine the same parameter of the cylindrical body at different positions when the cylindrical body rotates and moves in one direction.

[0040] Generally, the measuring device may measure at least a part of the cylindrical body. However, one or more parts of the cylindrical body can be measured by one or more measuring devices, and the entire cylindrical body can also be measured by one measuring device. Preferably, the measuring device measures one or more parts of the cylindrical body, and more preferably, the measuring device measures the entire cylindrical body.

[0041] Preferably, the angle between the normal of the supply plane and the center line of the measuring device (such as a camera), and / or, preferably, the angle between the rotation plane and the center line of the measuring device is greater than 45° and less than 135°, preferably between 60° and 120°, more preferably between 70° and 110°, more preferably between 80° and 100°, more preferably between 85° and 95°, and most preferably 90°.

[0042] Preferably, the measuring device can measure the curvature and the angle between the normal of the supply plane and the center line of the measuring device, and / or, preferably, the angle between the rotation plane and the center line of the measuring device is greater than 45° and less than 135°, preferably between 60° and 120°, more preferably between 70° and 110°, more preferably between 80° and 100°, more preferably between 85° and 95°, and most preferably 90°. The inventors surprisingly found that if the angle is close to 90°, for example between 70° and 110°, the curvature of the cylindrical body can be measured without being affected by other variables of the cylindrical body, which variables can be, for example, the thickness or ellipticity of the cylindrical body (see the detailed description below). If the distance between the measuring device and the cylindrical body is long enough, for example between 20 cm and 200 cm, preferably between 30 cm and 100 cm, and most preferably between 40 cm and 60 cm, the above-mentioned specific angle can be achieved by using more than one measuring device or only one measuring device, so that the angle changes only slightly when the cylindrical body moves relative to the measuring device and when the cylindrical body rotates.

[0043] Preferably, the measuring device is an object and geometry detection device, which preferably includes laser technology devices or cameras. More preferably, the measuring device is a camera. In this context, the center line of the measuring device (such as a camera) refers to the normal extending from the middle of the measuring device, such as the camera lens.

[0044] Sorting device

[0045] The detection device may optionally include a sorting device. The sorting device is configured to sort out cylindrical bodies with a quality below a specific value. Any value measured by the measuring device can be selected, for example, the curvature of the cylindrical body.

[0046] Cylindrical bodies with a quality below a specific value can be sorted out by, for example, clamping devices, blowers or trap doors, and preferably, by trap doors.

[0047] Bundle package of cylindrical body

[0048] Using the above detection device, a cluster package of cylindrical bodies with improved flatness can be obtained, and this cluster package can be used in high-demand applications. In addition, cylindrical bodies of lower quality can be separated and further used in low-demand applications. By using the above detection device, as long as the quality of a subset of the cylindrical bodies is sufficient to make the cluster package of cylindrical bodies have high quality, there is no need to specifically manufacture cylindrical bodies with very high quality. Additionally, by means of the above device, it can be ensured that all cylindrical bodies in the cluster package have very high quality because all cylindrical bodies are measured. For some applications, it does not matter if there are a few cylindrical bodies below a specific quality standard. Moreover, by using the above detection device, a cluster package of customized cylindrical bodies with specific quality can be obtained. In particular, the curvature of the cylindrical bodies can be reliably detected by the above detection device in the manner detailed in the measurement example and method section below.

[0049] Therefore, by using the above detection device, a cluster package including more than 5 cylindrical bodies can be obtained, wherein the curvature of all cylindrical bodies in the cluster package is below 1 mm. Preferably, the curvature of all cylindrical bodies in the cluster package is below 0.9 mm, more preferably below 0.8 mm, more preferably below 0.7 mm, more preferably below 0.6 mm, more preferably below 0.5 mm, more preferably below 0.4 mm, more preferably below 0.3 mm, more preferably below 0.2 mm, more preferably below 0.1 mm. The present invention does not specifically limit its lower limit. For economic considerations, preferably, the curvature of all cylindrical bodies in the cluster package is above 0.01 mm.

[0050] Preferably, the curvature of all cylindrical bodies in the cluster package is below 1 mm, preferably below 0.9 mm, more preferably below 0.8 mm, more preferably below 0.7 mm, more preferably below 0.6 mm, more preferably below 0.5 mm, more preferably below 0.4 mm, more preferably below 0.3 mm, more preferably below 0.2 mm, more preferably below 0.1 mm; and / or, more preferably, the curvature of all cylindrical bodies in the cluster package is above 0.01 mm; and / or, more preferably, wherein the cylindrical body is a tubular member; and / or, more preferably, wherein the cylindrical body is composed of a polymer or glass, more preferably composed of a cyclic olefin copolymer (COC), a cyclic olefin polymer (COP), a aluminosilicate glass or a borosilicate glass; and / or, more preferably, wherein the length of the cylindrical portion of the cylindrical body is above 1 cm to below 1000 cm, preferably above 20 cm to below 400 cm, more preferably above 60 cm to below 300 cm, more preferably above 100 cm to below 200 cm, most preferably above 120 cm to below 180 cm, and / or, the outer diameter of the cylindrical portion of the cylindrical body is from 2 mm to 100 mm, more preferably from 4 mm to 50 mm, more preferably from 6 mm to 35 mm, more preferably from 8 mm to 25 mm, most preferably from 10 mm to 20 mm; and / or, more preferably, a cluster package includes 5 to 5000, preferably 10 to 1000, more preferably 25 to 500, more preferably 50 to 300, most preferably 75 to 250 cylindrical bodies.

[0051] Preferably, all cylindrical bodies are measured by the detection device according to the present invention. The measurement details of the curvature will be described below. Brief Description of the Drawings

[0052] Figures 1 to 4 Exemplarily shows the detection device according to the present invention, wherein, Figure 1 and Figure 2 shows a side view of the detection device, Figure 3 and Figure 4 shows a top view of the detection device.

[0053] Figures 5 to 8 Shows how to measure the curvature. Detailed Description of the Invention

[0054] Measurement examples and methods

[0055] Figures 1 to 4What all the examples shown have in common is that the detection device includes a conveying device 1, a rotating device 2, and a measuring device 3. The conveying device 1 includes a conveying plane 4 and a supply plane 5. Usually, the detection device includes two conveying devices 1, each of which includes a conveying plane 4, and one or more supply planes 5 are fixed on the conveying plane 4. The rotating device 2 includes two rotating planes 6 / 6a. Usually, the detection device includes two rotating devices 2. The rotating plane 6 / 6a can be a static rotating plane 6( Figure 1 ), or it can include a moving rotating plane 6a, which preferably moves in the opposite direction relative to the conveying device 1 (see Figure 2 ).

[0056] The detection device includes one or more measuring devices 3, and the measuring device 3 can be located anywhere in the detection device. Thus, the position of the measuring device 3 depends on the property to be measured. If the detection device includes more than one measuring device 3, then more than one property can be easily measured in one detection device. Sometimes, it may be necessary to install more than one measuring device 3 of the same type to obtain an overall view of the cylindrical body 7. In one example, the two rotating planes 6 / 6a and / or the conveying plane 4 are parallel ( Figure 3 ). In another example, the distance between the two rotating planes 6 / 6a and / or the conveying plane 4 changes, i.e., decreases ( Figure 4 ) or increases. This may be beneficial if the measuring device 3 needs to measure the entire cylindrical body 7. In this case, more than one measuring device 3 of the same type can be installed at different positions to perform an overall detection of the entire cylindrical body 7 ( Figure 4 ). Another example (not shown) with the same effect is a detection device in which one rotating device 2 is diagonally arranged in a top view. The conveying device 1 is configured such that the cylindrical body 7 moves relative to the measuring device 3. In Figures 1 to 4 , the cylindrical body 7 moves in a specific direction 8. When the cylindrical body 7 reaches the detection device, the cylindrical body 7 contacts at least the conveying plane 4, and usually contacts the conveying plane 4 and the supply plane 5. In the detection device, when the cylindrical body 7 moves further relative to the measuring device 3, the cylindrical body 7 contacts the rotating plane 6 / 6a. Because the speed of the rotating plane 6 / 6a is different from that of the supply plane 5, the cylindrical body 7 begins to rotate around its rotation axis. When the cylindrical body 7 moves relative to the measuring device 3 and when the cylindrical body 7 rotates, one or more measuring devices 3 measure one or more properties. Through the rotation of the cylindrical body 7 and the specific position and focus of the measuring device 3, the entire circumference of the cylindrical body 7 can be measured.

[0057] Based on Figures 5 to 8Describe the method for measuring the degree of curvature. Based on Figure 5 The definition of the degree of curvature of the cylindrical body 7 will be described. The cylindrical portion of the cylindrical body 7 contacts two defined contact points 11, and the distance between these two contact points is 1000 mm. The degree of curvature herein refers to the maximum deviation length 12 between the outer surface of the cylindrical body at any position measured when the cylindrical body 7 rotates 360 degrees around its rotation axis and the ideal line 13 defined by the two contact points 11. If the cylindrical portion of the cylindrical body is longer than 1000 mm, the middle part of the cylindrical portion of the cylindrical body is placed in the middle of the two contact points for measurement.

[0058] Figure 6 and Figure 7 Exemplary measurements of the cylindrical body 7 with a degree of curvature are shown in Figure 6 As can be seen in Figure 6 and Figure 7 During the measurement, the cylindrical body 7 contacts the supply plane 5 defining the two contact points 11 and the rotation plane 6 / 6a. Thus, when the supply plane 5 moves in the direction 8, the cylindrical body 7 rotates. The measurement is carried out along the observation line. The measuring device 3 (not shown) measures the position x of the contact points 11 and the position of the outer surface of the cylindrical body 7 between the contact points 11 over time t. As can be seen in

[0059] InFigure 8 In it, a schematic diagram of the angle 15 between the normal line of the supply plane 5 and the measurement direction is shown. Additionally, the angle 16 between the rotation plane 6 / 6a and the measurement direction is shown. Both of these angles are 90°.

[0060] In summary, the steps for measuring the camber are as described below:

[0061] i) Bring the cylindrical part of the cylindrical body 7 into contact with two defined contact points 11, where the distance between the two contact points is 1000 mm;

[0062] ii) When the cylindrical body 7 rotates 360 degrees around its rotation axis, measure the maximum deviation length 12 between the outer surface of the cylindrical body at any position and the ideal line 13 defined by the two contact points 11, that is: the camber;

[0063] Wherein, if the length of the cylindrical part of the cylindrical body is greater than 1000 mm, place the middle part of the cylindrical part of the cylindrical body in the middle of the two contact points for measurement.
