Abstract
Description
【Technical Field】 【0001】 Generally, the present disclosure relates to edge protection attachment in a system for sheet coil packaging. 【Background Art】 【0002】 Coils of sheet metal need to be properly wrapped to protect the sheet metal during transportation and storage. In particular, the edges of the sheet metal coil need to be properly protected so that the sheet metal does not get damaged along the edges. US20230227188 describes the attachment of edge protection material onto the edges of a sheet coil in a system for sheet coil wrapping using two robotic arms and a wrapping tool. During the wrapping sequence, the first robotic arm inserts the wrapping tool into the central hole of the sheet coil and passes it to the second robotic arm, which transports the wrapping tool along the outside of the sheet coil and passes it back to the first robotic arm. [Problems of the Prior Art] 【0003】 Prior art edge protection attachment devices are very bulky and time-consuming to apply edge protection material to both the inner and outer edges of the sheet coil. Thus, there is a need for an improved edge protection attachment device for use in a system for sheet coil packaging. 【Summary of the Invention】 【0004】 This disclosure relates to an edge protection mounting device for use in a system for sheet coil packaging. The edge protection mounting device comprises a mounting arm mechanism having at least one edge protection material guide configured to guide edge protection material to the correct position along at least one edge of a sheet coil. The at least one edge protection material guide is shaped to guide the edge protection material so that it is laterally shifted away from the mounting arm mechanism. This allows the mounting arm mechanism of the edge protection mounting device to be positioned laterally to the sheet coil rather than above or below it, thereby allowing the system for sheet coil packaging to be much more compact. 【0005】 Furthermore, this disclosure relates to a system for sheet coil packaging. The system comprises: a sheet coil wrapping mechanism positioned for wrapping a sheet coil; a sheet coil rotating mechanism positioned to rotate the sheet coil while it is being wrapped by the sheet coil wrapping mechanism; and two edge protection mounting devices, each having a mounting arm mechanism including at least one edge protection material guide positioned to guide edge protection material to the correct position along at least one edge of the sheet coil as the sheet coil is being wrapped by the sheet coil wrapping mechanism and rotated by the sheet coil rotating mechanism, thereby securing the edge protection material to the edge of the sheet coil by the wrapping. The at least one edge protection material guide is shaped to guide the edge protection material so that it is shifted laterally from the mounting arm mechanism. This allows the mounting arm mechanism of the edge protection mounting device to be positioned laterally to opposite ends of the sheet coil rather than above or below the sheet coil, thereby making the entire system for sheet coil packaging much more compact. 【0006】 In one embodiment, each mounting arm mechanism includes an outer edge protection material guide configured to guide the edge protection material to the correct position along the outer edge of the sheet coil, and an inner edge protection material guide configured to guide the edge protection material to the correct position along the inner edge of the sheet coil. Such an edge protection mounting device makes it possible to apply both inner and outer edge protection much faster than is known from the prior art. 【0007】 In the embodiment, each mounting arm mechanism includes a hinge mechanism arranged to allow a portion of the mounting arm, including at least one edge protection material guide, to be moved out of the way if at least one edge protection material guide is not used. 【0008】 In the embodiment, each edge protection mounting device includes an arm support that supports the mounting arm mechanism, and the arm support includes a horizontal adjustment mechanism and a vertical adjustment mechanism. This allows the mounting arm mechanism to be positioned so that the edge protection material guide can guide the edge protection material to the correct position on the edge of the sheet coil. This makes it possible to easily adjust for sheet coils of various dimensions. 【0009】 In embodiments, the mounting arm mechanism supports an edge protection material coil containing edge protection material thin enough to be wound in a folded state. This means that it is not essential to provide a mechanism for folding the edge protection material between the edge protection material coil and the edge protection material guide. 【0010】 This disclosure also relates to an edge protection mounting material for use in the edge protection mounting device described above. The edge protection material has slits along both longitudinal sides, resulting in the formation of a series of tongues along both longitudinal sides. The edge protection material is positioned so as to be able to slide laterally when folded and to be guided to the correct position along the edge of the sheet coil. The slits allow the folded edge protection material to be guided to the correct position along the edge of the sheet coil from the side of the end of the sheet coil using an edge protection material guide. 【0011】 In embodiments, the shape of the tongue is determined by the size of the sheet coil on which the edge protection material is intended to be mounted, such that the tongue is shaped so that the slit is substantially closed at the base of the sheet coil when the edge protection material is mounted on the outer edge of the sheet coil. This allows the edge protection material to cover the surface around the edge of the sheet coil to the greatest extent possible. 【0012】 The length of the tongue is preferably matched to the width of at least one edge protection material guide so that the edge protection material is easily guided through at least one edge protection material guide. 【0013】 In one embodiment, the sheet coil wrapping mechanism includes a first industrial robot and a second industrial robot, which are arranged to wrap the sheet coil using a wrapping tool, using a sequence in which a first robot arm inserts a wrapping tool into the central hole of the sheet coil and hands the wrapping tool to a second robot arm, and the second robot arm transports the wrapping tool along the outside of the sheet coil and hands it back to the first robot arm, as the sheet coil is rotated by a sheet coil rotation mechanism. 【0014】 In an embodiment, the system further comprises a sheet coil rotation mechanism and two additional edge protection mounting devices to enable the sheet coil wrapping mechanism to wrap the sheet coil at two different positions. 【0015】 Furthermore, this disclosure relates to a method for sheet coil packaging. The method comprises: a step of wrapping a sheet coil using a sheet coil wrapping mechanism; and a step of feeding edge protection material along the edges of a sheet coil using two edge protection mounting devices as the sheet coil is rotated by a sheet coil rotation mechanism during the wrapping step of the sheet coil. Each edge protection mounting device has a mounting arm mechanism on which at least one edge protection material guide is positioned to guide the edge protection material to the correct position along at least one edge of the sheet coil as the sheet coil is wrapped by the sheet coil wrapping mechanism and rotated by the sheet coil rotation mechanism, thereby securing the edge protection material to the edges of the sheet coil by the wrapping. The step of feeding the edge protection material through at least one edge protection material guide includes a step of laterally shifting the edge protection material from the mounting arm mechanism. This makes it possible to position the mounting arm mechanism laterally to opposite ends of the sheet coil rather than above or below the sheet coil, thereby making the system for sheet coil packaging much more compact. 【0016】 In embodiments, the method further comprises the step of positioning an outer edge protection material guide on each mounting arm mechanism for guiding the edge protection material to the correct position along the outer edge of the sheet coil, and an inner edge protection material guide for guiding the edge protection material to the correct position along the inner edge of the sheet coil. Such a method makes it possible to apply both inner and outer edge protection much faster than known from the prior art. 【0017】 In embodiments, the method includes the step of moving a portion of the mounting arm, which includes at least one edge protection material guide, out of the way using a hinge mechanism included within the mounting arm mechanism, if at least one edge protection material guide is not required. 【0018】 In embodiments, the method includes a step of positioning the edge protection material guides using an arm support section, which includes a horizontal adjustment mechanism and a vertical adjustment mechanism provided within the edge protection mounting device, so that they guide the edge protection material to the correct position along the edge of the sheet coil. This allows the mounting arm mechanism to be positioned so that the edge protection material guides can guide the edge protection material to the correct position on the edge of the sheet coil. This makes it possible to easily adjust for sheet coils of various dimensions. 【0019】 In embodiments, the method comprises the step of using an edge protection material thin enough to be wound in a folded state on an edge protection material coil supported by a mounting arm mechanism. This means that it is not essential to provide a mechanism for folding the edge protection material between the edge protection material coil and the edge protection material guide. 【0020】 In an embodiment, the method comprises the step of using an edge protection material having slits along both longitudinal sides such that a series of tongues are formed on both longitudinal sides. The slits allow the edge protection material guide to guide the folded edge protection material from the side of the end of the sheet coil to the correct position along the edge of the sheet coil. 【0021】 In an embodiment, the method includes shaping the tongue such that the tongue is shaped such that the slit is substantially closed at the base of the sheet coil when the edge protection material is mounted on the outer edge of the sheet coil, with the shape of the tongue being determined by the size of the sheet coil. This allows the edge protection material to cover the surface around the edge of the sheet coil to the greatest extent possible. 【0022】 The length of the tongue is preferably matched to the width of at least one edge protection material guide so that the edge protection material is easily guided through at least one edge protection material guide. 【0023】 In one embodiment, the method includes the step of guiding the edge protection material in a folded state along the edge of the sheet coil. 【0024】 In an embodiment, the method is configured such that the sheet coil wrapping mechanism comprises a first industrial robot and a second industrial robot having a first robot arm and a second robot arm positioned to wrap a sheet coil using a wrapping tool, and the step of wrapping the sheet coil comprises a step of using a sequence in which, as the sheet coil is rotated by a sheet coil rotation mechanism, the first robot arm inserts the wrapping tool into the central hole of the sheet coil and hands the wrapping tool to the second robot arm, and the second robot arm transports the wrapping tool along the outside of the sheet coil and hands it back to the first robot arm. However, the method may operate similarly with other types of sheet coil wrapping mechanisms, and the use of industrial robots may not be essential. 【0025】 In some embodiments, the edge protection material comprises plastic and / or corrugated cardboard. 【0026】 In this embodiment, the sheet coil is a sheet metal coil. 【0027】 The scope of the present invention is defined by the claims, which are incorporated herein by reference. Those skilled in the art will, by considering the following detailed description of one or more embodiments, more fully understand the embodiments of the present invention and recognize their additional advantages.

It should be understood that similar reference numbers are used to identify similar elements shown in one or more of the figures. [Modes for carrying out the invention] 【0036】 This disclosure relates to a system and method for sheet coil packaging. Embodiments of the disclosed solution are presented in further detail with reference to the figures. 【0037】 Figure 1 shows a system 100 for sheet coil packaging. The system 100 shown in Figure 1 comprises two pairs of sheet coil wrapping mechanisms 112, 113, each equipped with two industrial robots, and two pairs of edge protection mounting devices 200, each pair arranged with a sheet coil rotating mechanism 120, which is configured to rotate a sheet coil 116 so that it is wrapped. The sheet coil wrapping mechanisms 112, 113 are configured to wrap the sheet coil 116 as the sheet coil 116 is rotated by the sheet coil rotating mechanism 120. Thus, the sheet coil 116 is wrapped preferably in sync with the delivery of edge protection material 400 from the edge protection mounting device 200, and as a result, the edge protection material 400 is secured to the sheet coil 116 by the wrapping as the sheet coil 116 is rotated by the sheet coil rotating mechanism 120. 【0038】 In the system 100 shown in Figure 1, the same sheet coil wrapping mechanisms 112, 113 may wrap the sheet coil 116 on multiple sheet coil stations on both sides of the sheet coil wrapping mechanisms 112, 113 in synchronization with the delivery of edge protection material 400 from the currently operating pair of edge protection mounting devices 200, so that the edge protection material 400 is secured to the sheet coil 116 by the wrapping as the sheet coil 116 is rotated by the sheet coil rotation mechanism 120. However, the system 100 may comprise only one sheet coil station, and consequently only one pair of edge protection mounting devices 200 and one sheet coil rotation mechanism 120. The delivery of the edge protection material may be performed using a drive unit described later, thereby allowing the delivery of the edge protection material to be performed in synchronization with the sheet coil wrapping. 【0039】 Since it is desirable to have edge protection material 400 on both sides of the sheet coil 116, preferably there are two edge protection mounting devices 200, one positioned beside each end of the sheet coil 116. The fact that the edge protection mounting devices 200 are positioned beside the sheet coil 116 rather than above or below it makes the entire system for sheet coil packaging much more compact. Thus, the two edge protection mounting devices 200 are positioned beside the sheet coil 116 at opposite ends so that as the sheet coil 116 is rotated by the sheet coil rotating mechanism 120, the edge protection material 400 can be fed and guided to the correct position along the edge of the sheet coil 116. Figures 2a to 2b show different embodiments of the two edge protection mounting devices 200 arranged in the system 100 for sheet coil packaging with the sheet coil rotating mechanism 120, which is positioned to allow the sheet coil 116 to be rotated and wrapped. Figures 2c to 2e are close-up views of the edge protection mounting devices 200. 【0040】 The shown edge protection mounting device 200 comprises a mounting arm mechanism 215 supported by an arm support 230. An edge protection material coil 250 is positioned on the first end of the shown mounting arm mechanism 215. The edge protection material coil 250 has a conical shape because the edge protection material 400 is wound on the edge protection material coil 250 in a folded state. The folded edge protection material 400 is preferably wound on the edge protection material coil 250 with a slight offset in each turn. However, it is also possible to use an edge protection material coil 250 that is not supported by the mounting arm mechanism 215. It is also not essential that the edge protection material 400 is wound on the edge protection material coil 250 in a folded state; instead, there may be a mechanism for bending the edge protection material provided between the edge protection material coil 250 and the edge protection material guides 310, 320. 【0041】 As shown in Figures 2b and 2d, the edge protection mounting device 200 may be configured to mount both outer and inner edge protection simultaneously using the same type of edge protection material 400. Therefore, the mounting arm mechanism 215 shown in Figures 2b and 2d comprises two mounting arms, namely an outer mounting arm 210 and an inner mounting arm 220. The outer edge protection is mounted using the outer mounting arm 210, and the inner edge protection is mounted using the inner mounting arm 220. An outer edge protection material guide 310 is positioned at the end of the outer mounting arm 210. Correspondingly, an inner edge protection material guide 320 is positioned at the end of the inner mounting arm 220. 【0042】 The same edge protection material coil 250 may be arranged, for example, by having two separate windings of edge protection material 400 on the same edge protection material coil 250, to enable the feeding of edge protection material 400 to both the outer edge protection material guide 310 and the inner edge protection material guide 320. Feeding of the edge protection material may be performed using a drive unit comprising a drive wheel 800. The drive wheel 800 may be arranged to feed material for inner edge protection, outer edge protection, or both inner and outer edge protection. The drive wheel may be connected to a drive means (not shown) that actively feeds the material, or the wheel 800 may rotate by inertia to allow the material to pass through without influence. The drive unit may be arranged to synchronize the feeding of the edge protection material with the wrapping of the coil. Two different edge protection material coils 250 may be present. In this case, both edge protection material coils 250 may be placed on the mounting arm mechanism 215, only one of them may be placed on the mounting arm mechanism 215, or neither of them may be placed on the mounting arm mechanism 215. One or more edge protection material coils 250 may be placed separately from the mounting arm mechanism 215 in order to supply the edge protection material 400 to the mounting arm mechanism 215. 【0043】 When the edge protection mounting device 200 shown in Figures 2a, 2c, and 2e is used, the edge protection material may be mounted on the inner edge of the sheet coil 116 before wrapping begins. US20230227188 describes a method for creating a ring of edge protection material and mounting it on the inner edge of the sheet coil 116. It is also possible to simply pick up a pre-made ring of edge protection material and mount it on the inner edge of the sheet coil 116 before wrapping begins. 【0044】 Figure 3a is a close-up view of the outer edge protection material guide 310. The outer edge protection material guide 310 is attached to the outer mounting arm 210 of the mounting arm mechanism 215, preferably to the end of the outer mounting arm 210, and is shaped to allow the folded edge protection material 400 to be guided to the correct position on the outer edge of the sheet coil 116. However, the shape of the outer edge protection material guide 310 makes it difficult for folded edge protection material 400 that is too rigid to be guided through it. Therefore, when using the outer edge protection material guide 310 shown in Figure 3a, it is essential to use edge protection material 400 in which slits 410, 420 are located on both sides of the fold 450, resulting in the formation of a series of tongues 430, 440. Such edge protection material 400 is shown in Figures 4a to 4c. The slits 410 and 420 are flexible enough to guide the edge protection material 400 through the indicated outer edge protection material guide 310, thereby allowing the actual material (preferably plastic and / or corrugated cardboard) to be laterally displaced from the mounting arm mechanism 215 despite being very rigid. As described above, the edge protection material 400 does not need to be wound in a folded state on the edge protection material coil 250; instead, a mechanism for folding the edge protection material can be provided between the edge protection material coil 250 and the outer edge protection material guide 310. 【0045】 Figure 3b is a close-up view of the inner edge protection material guide 320. The inner edge protection material guide 320 is attached to the inner mounting arm 220 of the mounting arm mechanism 215, preferably to the end of the inner mounting arm 220, and is shaped to allow the bent edge protection material 400 to be guided from a location not above or below the sheet coil 116 to the correct position on the inner edge of the sheet coil 116 at the central hole 118 of the sheet coil 116. 【0046】 The mounting arm mechanism 215 preferably moves such that, as the sheet coil 116 is rotated by the sheet coil rotation mechanism 120, the outer edge protection material guide 310 is positioned to apply the folded edge protection material 400 along the outer edge of the sheet coil 116, while at the same time, the inner edge protection material guide 320 is positioned to apply the folded edge protection material 400 along the inner edge of the sheet coil 116. The arm support 230 is preferably arranged to be easily adjustable both horizontally and vertically so as to facilitate positioning the mounting arm mechanism 215 so that the outer edge protection material guide 310 and the inner edge protection material guide 320 guide the folded edge protection material 400 to the correct position on the edge of the sheet coil 116. Therefore, the arm support 230 preferably comprises both a horizontal adjustment mechanism 240 and a vertical adjustment mechanism 245. This makes it possible to easily adjust for sheet coils 116 of various dimensions. 【0047】 Therefore, an edge protection mounting device 200 for use in a system 100 for sheet coil packaging may comprise a mounting arm mechanism 215 comprising at least one edge protection material guide 310, 320 configured to guide the edge protection material 400 to the correct position along at least one edge of a sheet coil 116, the at least one edge protection material guide 310, 320 being shaped to guide the edge protection material 400 so as to be laterally shifted away from the mounting arm mechanism 215. The edge protection mounting device 200 may further comprise an arm support 230 supporting the mounting arm mechanism 215. The mounting arm mechanism 215 has a first end on which an edge protection material coil 250 comprising the edge protection material 400 wound in a folded state may be positioned, and a second end comprising at least one mounting arm 210, 220 on which the edge protection material guide 310, 320 is positioned. However, it is not essential that the edge protection material coil 250 is supported by the mounting arm mechanism 215, nor is it essential that the edge protection material 400 is wound around the edge protection material coil 250 in a folded state. 【0048】 A system 100 for sheet coil packaging preferably comprises: sheet coil wrapping mechanisms 112, 113 arranged for wrapping a sheet coil 116; a sheet coil rotating mechanism 120 arranged to rotate the sheet coil 116 while it is being wrapped by the sheet coil wrapping mechanisms 112, 113; and two edge protection mounting devices 200, each having a mounting arm mechanism 215 including at least one edge protection material guide 310, 320 arranged to guide an edge protection material 400 to the correct position along at least one edge of the sheet coil 116 as the sheet coil 116 is being wrapped by the sheet coil wrapping mechanisms 112, 113 and rotated by the sheet coil rotating mechanism 120, thereby securing the edge protection material 400 to the edge of the sheet coil 116 by the wrapping, the at least one edge protection material guide 310, 320 being shaped to guide the edge protection material 400 so that it is laterally shifted away from the mounting arm mechanism 215. Once the edge protection material 400 is secured to the edge of the sheet coil, the drive wheel 800 can be rotated by inertia. Thus, the edge protection material will be unwound from the coil 250. As shown in Figures 1 and 2a to 2b, the edge protection mounting device 200 is preferably positioned laterally to each other's opposite ends of the sheet coil 116 when the sheet coil 116 is rotated by the sheet coil rotation mechanism 120. The fact that the edge protection mounting device 200 is positioned laterally to the sheet coil 116 rather than above or below it makes the entire system 100 for sheet coil packaging much more compact. 【0049】 While the illustrated embodiments show that the edge protection material 400 is wrapped over one or both edges of the coil 116 from below, it should be noted that wrapping the edge protection material 400 over the inner and outer edges can also be done by wrapping the edge protection material from the top side of the coil 116. 【0050】 Figures 4a to 4c show edge protection materials used with the edge protection mounting device 200 described above. As described above, the edge protection material 400 preferably has slits 410, 420 along both longitudinal sides, resulting in a series of tongues 430, 440 being formed on both longitudinal sides. The shape of the tongues 430, 440 is preferably determined by the size of the sheet coil 116 on which the edge protection material 400 is intended to be mounted. As described above, it is essential that the edge protection material 400 has slits 410, 420, because these slits 410, 420 make the edge protection material 400 flexible enough to be guided through the outer edge protection material guide 310 shown, thereby allowing it to be laterally shifted away from the mounting arm mechanism 215 despite the actual material (preferably plastic and / or corrugated cardboard) being very rigid. The slits 410 and 420 should preferably not be simply straight cuts in the material, as this would cause the tongues 430 and 440 to overlap when the material is bent as it is mounted around the outer edge of the sheet coil 116. However, for optimal protection of the sheet coil 116, it is still preferable that the edge protection material 400 covers the surface around the edge to the greatest extent possible. Therefore, it is preferable to shape the tongue 440 such that the slit 420 is substantially closed at the base of the sheet coil 116 when the edge protection material 400 is mounted on the outer edge of the sheet coil 116. This is shown in Figure 4b. 【0051】 If the edge protection material 400 is symmetrical, and as a result the slits 410, 420 and tongues 430, 440 have the same shape along both longitudinal sides of the edge protection material 400, it becomes easier to use the same edge protection material 400 for all edge protection mounting devices 200. However, it is also possible to use an asymmetrical edge protection material 400 in which only the slits 420 and tongues 440 located at the base of the sheet coil 116 are shaped to be substantially closed when the edge protection material 400 is mounted on the outer edge of the sheet coil 116. The slits 410 and tongues 430 located on the outside of the sheet coil 116 may simply be straight cuts in the material, as this means that the edge protection material 400 covers the surface around the edge to the greatest extent possible. 【0052】 The length of the tongues 430 and 440 is preferably matched to the width of at least one edge protection material guide 310 or 320 so that the edge protection material 400 is easily guided through at least one edge protection material guide 310 or 320. 【0053】 The edge protection material 400 is preferably guided in a folded state along the edge of the sheet coil to the correct position. As described above, the edge protection material 400 may be wound in a folded state on the edge protection material coil 250, however, it is possible to provide a mechanism for folding the edge protection material between the edge protection material coil 250 and the outer edge protection material guide 310 instead. 【0054】 The sheet coil wrapping mechanism may comprise, for example, two industrial robots 112, 113 arranged to wrap the sheet coil 116 as it is rotated by a sheet coil rotation mechanism 120, as shown in Figure 5. Each of the industrial robots 112, 113 preferably has robot arms 108, 109 arranged to wrap the sheet coil 116 using a wrapping tool 110. The first robot arm 108 inserts the wrapping tool 110 into the central hole 118 of the sheet coil 116 and hands the wrapping tool 110 to the second robot arm 109. The second robot arm 109 then transports the wrapping tool 110 along the outside of the sheet coil 116 and hands it back to the first robot arm 108. This sequence then continues as the sheet coil 116 is rotated by the sheet coil rotation mechanism 120. In system 100, two industrial robots 112 and 113 wrap the sheet coil 116 in synchronous motion with the delivery of edge protection material 400, so that the edge protection material 400 is secured to the sheet coil 116 by wrapping as the sheet coil 116 is rotated by the sheet coil rotation mechanism 120. Preferably, an integrated cutting mechanism is present within each edge protection mounting device 200 so that the edge protection material 400 can be cut to a desired length before the wrapping is complete. The length is preferably calculated based on a defined diameter of the sheet coil 116. 【0055】 As shown in Figure 5, each of the robot arms 108, 109 may be equipped with wrapping material clamps 146, 147, preferably mounted near the distal ends of the robot arms 108, 109, configured to hold strips of wrapping material. When the sheet coil 116 is completely wrapped, the strips of wrapping material may be clamped at the clamping station 156 and the strips may be cut. For the purpose of cutting the wrapping material, the strips of wrapping material may be wrapped around the shaft 159 at the clamping station 156 to keep track of where the wrapping material is in robot space, and the strips may then be cut. Before the strips of wrapping material are cut, the strips may be held by one of the clamps 146, 147 of the robot arms 108, 109 so that the remaining wrapping material on the roll 106 on the wrapping tool 110 is ready for a new wrapping procedure. Untreated end strips of wrapping material wrapped around the coil may be positioned to adhere to the wrapping, for example, by self-adhesive properties. The wrapping material may be, for example, a stretchable film of a plastic material. 【0056】 System 100 operates similarly to other types of sheet coil wrapping mechanisms, and the use of industrial robots 112, 113 may not be necessary. 【0057】 After the wrapping operation at the wrapping station, a crane or similar device may be used to lift the wrapped sheet coils and move them to a post-processing station, where additional packing operations may be performed manually or semi-automatically. 【0058】 System 100 may include a robot jig 114 having a first leg 148 and optionally an intersecting second leg 149. The first leg 148 of the robot jig 114 is configured such that a first robot base frame 150 and a second robot base frame 151 are positioned spaced apart on the first leg 148. The second leg 149 of the robot jig 114 may be configured such that a first coil roller contact base 152 is positioned at the end of the second leg 149. The sheet coil rotation mechanism 120 may be positioned relative to the robot jig 114 such that, for example, thanks to a positioning beam having a contact base, the sheet coil rotation mechanism 120 does not physically or mechanically contact the robot jig 114 during operation in order to avoid transmitting power to the robot jig 114. 【0059】 In an embodiment comprising two sheet coil stations, the robot jig 114 may include two sheet coil rotating mechanisms 120, and consequently, a second coil roller contact base 153 positioned at the other end of the second leg 149. 【0060】 The robot jig 114 shown in Figure 5 is configured such that two robot base mounts 150, 151 are positioned spaced apart on the first leg of a cross geometry, and first and second coil roller contacts 152, 153 are positioned spaced apart on the second leg of a cross geometry.

The first and second sheet coil rotating mechanisms 120 are positioned on their respective coil roller contacts 152, 153. Such a sheet coil rotating mechanism 120 is known in itself and typically comprises a cradle of two rollers that can be actuated to impart rotational motion to a sheet coil 116 positioned within the cradle. 【0061】 In the embodiment shown in Figure 5, the robot jig 114 is composed of a substantially cross geometry of legs that are substantially perpendicular to each other and have one or more bars, i.e., the bars constitute the legs, and thus one or more bars intersect at substantially right angles. Other intersection angles may consist of the adapted configuration of the robot, their range, and their movement. In the embodiment shown in Figure 5, each leg comprises two parallel bars. Other embodiments include only the first leg, as described above. 【0062】 The sheet coil 116 is found in a variety of sizes. Large coils can have a length of 2300 mm, while typical sizes range from 1200 mm to 1500 mm in length, and can be as small as 800 mm. The central hole 118 often has an inner diameter of 508 mm or 610 mm, although smaller diameters of around 420 mm also exist.

The wrapping material clamping station 156 may be provided with one or more wrapping material clamps 157, 158 configured to hold strips of wrapping material. 【0064】 The system 100 may further comprise a roll magazine 160 for storing multiple rolls 106 of wrapping material available to one or more of the industrial robots 112, 113. The roll magazine 160 may consist, for example, one or more roll holders 164 and associated wrapping material clamps 162, 166 for each roll of wrapping material. Each of the wrapping material clamps 162, 166 may be configured to hold a strip of wrapping material. The roll magazine 160 may be positioned and located within reach of at least one robot during use, for example, to the side of the robot setup, or in front of one of the robots, for example, to the side of the coil roller. 【0065】 System 100 may further include a measuring mechanism configured to measure the position and dimensions of a sheet coil 116 positioned on a sheet coil rotating mechanism 120 for packaging with wrapping material. In embodiments, the measuring system includes, for example, one or more laser measuring tools mounted on one or both of the robot arms 108, 109. When such a laser measuring tool is mounted on a robot arm, it is preferably positioned so that it has an optical path that is not obstructed by the roll of wrapping material attached to the wrapping tool 110. When measuring position and dimensions, System 100 is configured to find the center of the coil, trace its contour, and calculate the position and dimensions. 【0066】 System 100 may further comprise a robot control system 170 configured to control the movement of industrial robots 112, 113 with respect to a sheet coil 116 positioned on a sheet coil rotating mechanism 120 within System 100. The robot control system 170 may comprise input / output interfaces configured to be communicably coupled to the industrial robots 112, 113, one or more sheet coil rotating mechanisms 120, and / or a human / machine interface (not shown), for example, in the form of a GUI that generates a dashboard. The robot control system 170 may be used to determine the dimensions of the sheet coil 116 before applying edge protection. 【0067】 Figure 6a shows a wrapping tool 110 configured for handing between robot arms 108 and 109, with a roll holder shaft 104 for holding a roll of wrapping material 106, and Figure 6b shows the wrapping tool 110 of Figure 6a with the roll of wrapping material 106 positioned on the roll holder shaft 104. 【0068】 The wrapping tool 110 preferably comprises two opposite ends 102, 103, each end having coupling tool pieces 122, 123 configured to interface with robot arms 108, 109. The wrapping tool 110 preferably further comprises a roll holder shaft 104 configured to hold a roll of packaging material 106, the holder shaft 104 being rotatably mounted at one end, preferably substantially midway between the opposite ends 102, 103, and preferably projecting substantially perpendicular to an axis extending between the opposite ends 102, 103. The wrapping tool 110 may be provided with a housing 105 comprising one or more cover plates 107A, 107B. 【0069】 In an embodiment, robot arms 108, 109 are each provided with coupling robot pieces 124, 125, such as grippers or master pieces of tool changers, configured to grasp or engage with the respective coupling tool pieces 122, 123 of the lapping tool 110. As shown in Figure 6a, robot arm 109 can be coupled to the lapping tool 110 via coupling robot piece 124, which engages with the left-hand robot tool piece 122 in Figure 6a at one end 102. At the other end 103 of the right-hand lapping tool 110, a second coupling tool piece 123 is available for coupling to another robot arm 108, which is not shown in Figure 6a. 【0070】 The coupling toolpieces 122 and 123 of the lapping tool 110 are configured to transmit actuation force from the power supply line of a robot, such as an industrial robot. In different embodiments, the actuation force may be in the form of, for example, pneumatic power, hydraulic power, or electric power. The coupling section may typically be connectable by a bayonet coupling and / or configured to lock into the correct position using actuation force controlled by the respective robot. 【0071】 A coupling configured to interface between an industrial robot and a lapping tool 110 may be configured in the form of a robot tool changer, with coupling tool pieces 122, 123 configured to be matesable with coupling master pieces 124, 125 of the tool changer mounted on the respective robot arms 108, 109. Such a coupling may consist of presence sensors adapted to detect or indicate that the lapping tool 110 is attached to the robot arms 108, 109. The presence sensors may be based on pneumatic or electrical signals that are integrated into the tool changer function of the coupling and are readable by the robot control system, or they may be located laterally on the coupling in the form of an electrical presence detector coupled to the robot control system, for example. 【0072】 The roll holder shaft 104 may include roll fixtures 140, 141 configured to releasably secure rolls of wrapping material to the roll holder shaft 104. For example, portions 140, 141 of the roll holder shaft 104 may be configured to be radially expandable to allow the roll fixtures to releasably secure rolls of wrapping material to the roll holder shaft 104. This can be implemented, for example, as one or more inflatable bladders 140, 141 that are controllably inflatable using pneumatic power, i.e., pressurized air, transmitted from each robot via a coupling interface. Alternatively, the roll fixtures 140, 141 may be actuated, for example, by electric or hydraulic power. One embodiment comprises first and second radially expandable portions 140, 141 in the form of an expandable bladder on a shaft 104, wherein the first expandable portion is configured to secure a roll of wrapping material having a first smaller width, and consequently, the combined first and second expandable portions are configured to secure a roll of wrapping material having a larger width. 【0073】 The wrapping tool 110 may further include at least one motor configured to drive, prevent, and / or brake the rotation of the roll holder shaft 104. This may enable the roll holder shaft 104 to be driven in a first rotational direction, e.g., forward, to unwind the wrapping material from the roll in synchronization with the movement of a robot, or in a second rotational direction, e.g., backward, to wind or wind the wrapping material onto the roll, e.g., to collect excess wrapping material or to increase the tension of the wrapping material. This may further enable the rotation of the roll to be prevented, e.g., to maintain the unwound strip of wrapping material to a specific length or to maintain the current tension of the wrapping material. Furthermore, this may enable the rotation of the roll to be braked, e.g., to obtain, change, or maintain a specific tension on the roll. 【0074】 Figure 7 schematically illustrates method 700 for sheet coil packaging. Method 700 may include the following: 【0075】 Stage 770: The stage of wrapping the sheet coil 116 using the sheet coil wrapping mechanisms 112 and 113. 【0076】 Step 780: Using two edge protection mounting devices 200 described above, during the wrapping 770 of the sheet coil 116, the edge protection material 400 is fed along the edge of the sheet coil 116 as the sheet coil 116 is rotated by the sheet coil rotating mechanism 120, each edge protection mounting device 200 having a mounting arm mechanism 215 on which at least one edge protection material guide 310, 320 is positioned to guide the edge protection material 400 to the correct position along at least one edge of the sheet coil 116 as the sheet coil 116 is wrapped by the sheet coil wrapping mechanisms 112, 113 and rotated by the sheet coil rotating mechanism 120, thereby fixing the edge protection material 400 against the outer edge of the sheet coil 116 by the wrapping, where Step 780 of feeding the edge protection material 400 through the edge protection material guides 310, 320 includes a step of laterally shifting the edge protection material 400 from the mounting arm mechanism 215. 【0077】 This allows the mounting arm mechanism 215 to be positioned laterally to opposite ends of the sheet coil 116. The fact that the mounting arm mechanism 215 is positioned laterally to the sheet coil 116, rather than above or below it, makes the entire system 100 for sheet coil packaging much more compact. 【0078】 In this embodiment, the sheet coil 116 is a sheet metal coil. 【0079】 Method 700 may further comprise one or more of the following: 【0080】 Step 710: The sheet coil wrapping mechanism 112, 113 is arranged to include a first industrial robot 112 and a second industrial robot 113 having a first robot arm 108 and a second robot arm 109 positioned to wrap the sheet coil 116 using a wrapping tool 110, and Step 770 for wrapping the sheet coil 116 has a step that uses a sequence in which, as the sheet coil 116 is rotated by the sheet coil rotation mechanism 120, the first robot arm 108 inserts the wrapping tool 110 into the central hole 118 of the sheet coil 116 and hands the wrapping tool 110 to the second robot arm 109, and the second robot arm 109 transports the wrapping tool 110 along the outside of the sheet coil 116 and hands it back to the first robot arm 108. However, Method 700 may also work with other types of sheet coil wrapping mechanisms, and the use of industrial robots 112, 113 may not be essential. 【0081】 Step 720: The step of positioning an outer edge protection material guide 310 on each mounting arm mechanism 215 to guide the edge protection material 400 to the correct position along the outer edge of the sheet coil 116, and an inner edge protection material guide 320 to guide the edge protection material 400 to the correct position along the inner edge of the sheet coil 116. In this manner, both inner and outer edge protection can be applied much faster than known from the prior art. 【0082】 Step 730: Using the arm support section 230, which includes a horizontal adjustment mechanism 240 and a vertical adjustment mechanism 245 provided within the edge protection mounting device 200, the edge protection material guides 310, 320 are positioned so that they guide the edge protection material 400 to the correct position along the edge of the sheet coil 116. This makes it possible to easily adjust for sheet coils 116 of various dimensions. 【0083】 Stage 740: A stage in which an edge protection material 400 is used that is thin enough to be wound in a folded state on an edge protection material coil 250 supported by a mounting arm mechanism 215. This means that it is not necessary to provide a mechanism for folding the edge protection material between the edge protection material coil and the edge protection material guide. 【0084】 Step 750: Step of using edge protection material 400 including slits 410, 420 along both longitudinal sides so that a series of tongues 430, 440 are formed on both longitudinal sides. The slits allow the edge protection material guide to guide the folded edge protection material from the side of the end of the sheet coil to the correct position along the edge of the sheet coil. 【0085】 Step 755: A step in which the shape of the tongues 430 and 440 of the edge protection material 400 is determined by the size of the sheet coil 116, such that the tongues 430 and 440 are shaped such that the slit 420 is substantially closed at the base of the sheet coil 116 when the edge protection material 400 is mounted on the outer edge of the sheet coil 116. This allows the edge protection material 400 to cover the surface around the edge of the sheet coil 116 to the greatest extent possible. 【0086】 Stage 760: The stage of guiding the edge protection material 400 in the correct position, folded along the edge of the sheet coil 116. 【0087】 Step 790: If at least one edge protection material guide 310, 320 is not needed, the step involves using the hinge mechanism 260 contained within the mounting arm mechanism 215 to move a portion of the mounting arm mechanism 215, including at least one edge protection material guide 310, 320, out of the way. 【0088】 The foregoing disclosure is not intended to limit the invention to the exact form disclosed or to any particular field of use.
