Description

Technical Field

[0001] The present invention provides a wrapping unit, a wrapping system and a wrapping method, and particularly relates to a wrapping unit, a wrapping system and a wrapping method suitable for automatically wrapping a membrane around objects of different sizes. Prior Technology

[0002] Logistics is an indispensable service in people's daily lives. Generally speaking, depending on the type, size, and value of the goods to be transported, there are corresponding logistics equipment and conditions for picking up, placing, and storing the goods; otherwise, the goods are prone to damage or even loss during transportation. Summary of the Invention

[0003] Taking the semiconductor industry as an example, packaged wafer cassettes or other precision semiconductor component housings are typically further sealed in shipping cartons, with appropriate securing and cushioning materials (such as polystyrene) placed inside to prevent these items from sliding or tipping over. To allow these cartons to be moved at once, a film made of a polymer material (such as polyethylene) is usually used to wrap multiple cartons together, reducing relative displacement between them. However, during the wrapping process, if the contents of some cartons are relatively light, they may be pulled away from their original position by the film, causing the wrapping process to be interrupted. Furthermore, because the film itself has a certain tension, if the dimensions of different layers of cartons change (e.g., stacking small cartons on large cartons) or the number of stacked cartons differs (e.g., stacking only one carton on four cartons), the film will be limited to its maximum size and can only adhere to the outer perimeter of the larger or more numerous cartons, creating gaps between the smaller or fewer cartons and the film, making them difficult to secure.

[0004] The inventor then devoted his mind and effort to research and development, and finally developed a wrapping unit, wrapping system and wrapping method suitable for automatically wrapping film onto objects of different sizes, in order to improve wrapping efficiency and enhance the ability to fix the objects to be wrapped.

[0005] This invention provides a wrapping unit suitable for a film body and comprising a fixing module and a wrapping module.

[0009] In one embodiment, the above-described film-coating device is adapted to tilt or rotate relative to the film-coating pivot along an alignment direction, and the film exit direction is not parallel to the alignment direction.

[0010] In one embodiment, the above-described film-coating device includes a film-coating body, a film-supplying component, a film-discharging component, and a driving component. The film-supplying component is connected to the film-coating body; the film-discharging component is connected to the film-coating body and spaced apart from the film-supplying component; the driving component is connected to the film-coating body and disposed between the film-supplying component and the film-discharging component, and the driving component is adapted to guide a film from the film-supplying component to the film-discharging component.

[0011] In one embodiment, the above-mentioned film-coating device further includes a film-forming component, wherein the film-forming component is connected to the film-coating body and disposed between the film-supplying component and the film-discharging component.

[0012] In addition, the present invention also provides a wrapping system, including a carrier unit, a wrapping unit as described above, and a receiving unit, wherein the wrapping unit is configured corresponding to the carrier unit, and the receiving unit is configured adjacent to the wrapping unit.

[0013] In one embodiment, the aforementioned bearing unit includes at least one support member and a lifting member, wherein the lifting member is connected to the support member and is adapted to move along a lifting direction.

[0014] In one embodiment, the aforementioned support member is a plurality of rollers, and the lifting member is arranged at intervals with the rollers.

[0015] In one embodiment, the aforementioned carrying unit includes a carrying platform and a plurality of carrying sensors, which are disposed on the carrying platform and adapted to detect an object to be wrapped on the carrying platform.

[0016] In one embodiment, the film collection unit includes a film collection base and a film collection device, and the film collection device is slidably connected to the film collection base.

[0017] In one embodiment, the film receiving unit further includes a film receiving connector, wherein the film receiving device is slidably disposed on the film receiving connector, and the film receiving connector is pivotally connected to the film receiving base.

[0018] In one embodiment, the film-collecting unit described above includes a heating element, an air gun, or a pair of scissors.

[0019] In addition, the present invention also provides a wrapping method, comprising: providing a fixing module, a wrapping module, a film body, and an object to be wrapped; disposing the film body on a wrapping device of the wrapping module; fixing the object to be wrapped through the fixing module; driving a wrapping pivot member of the wrapping module to rotate relative to the object to be wrapped; and driving the film body to wrap over the object to be wrapped from the wrapping device, wherein the tension of the film body changes during the rotation of the wrapping pivot member.

[0024] In one embodiment, the wrapping method further includes: providing a film-collecting unit; and driving a film-collecting base of the film-collecting unit to move or rotate, so that a film-collecting device connected to the film-collecting base abuts against the film body.

[0025] Therefore, the wrapping unit of the present invention can fix the object to be wrapped by the fixing module, and wrap the film around the object by the wrapping module, thereby preventing the object from being moved by the film and affecting the wrapping process. During wrapping, the wrapping device can slide relative to the wrapping pivot member along the film exit direction, and the tension control member can adjust the tension of the film according to the size of the object to be wrapped. Therefore, even if the size of the object to be wrapped changes at different positions, the film can still be reliably covered on the surface, thereby improving the ability to fix the object to be wrapped.

[0028] The foregoing description and other technical contents, features, and effects of this invention will be clearly presented in the following detailed description of preferred embodiments with reference to the accompanying drawings. It is worth noting that the directional terms mentioned in the following embodiments, such as up, down, left, right, front, or back, are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the invention. Furthermore, in the following embodiments, the same or similar elements will be represented by the same or similar reference numerals.

[0029] Please refer to Figure 1, which is a perspective view of an embodiment of the wrapping system of the present invention. The wrapping system 1 of this embodiment is suitable for wrapping an object 2 to be wrapped with objects such as packaging film, wrapping paper, bandages, or tape. The object 2 to be wrapped is, for example, a cardboard box containing semiconductor components, but the present invention does not limit this. In detail, the wrapping system 1 includes a frame 10, a carrier unit 20, a wrapping unit 30, and a film receiving unit 40. The carrier unit 20 is housed within the frame 10; the wrapping unit 30 is configured corresponding to the carrier unit 20, and in this embodiment, for example, is mounted on the frame 10 and located above the carrier unit 20; while the film receiving unit 40 is configured adjacent to the wrapping unit 30.

[0030] Please refer to Figures 2 and 3, where Figure 2 is a perspective view of the support unit in Figure 1, and Figure 3 is a right-side view of Figure 2. In this embodiment, the support unit 20 may include a support platform 22, a lifting member 24, and a plurality of support sensors 26. The support platform 22 is, for example, a longitudinally extending three-dimensional base and includes at least one support member 22a. In this embodiment, the support member 22a is a roller and there are a plurality of rollers. These rollers are adapted to be driven by a transmission mechanism such as a motor or pulley to actively or passively pivot, and directly or indirectly support the object 2 to be wrapped. Preferably, the support platform 22 may also include a tray 22b independent of the support member 22a, and the support member 22a is adapted to support the tray 22b and move the tray 22b to a specific position. In some possible embodiments, the carrying platform 22 may also be provided with limiting members around the aforementioned specific location to restrict the position of the tray 22b. In this way, when performing the wrapping operation, the user can place the item to be wrapped 2 on the tray 22b, move the tray 22b to the specific position through the operation of the support member 22a, and fix it through the limiting members, thereby eliminating the inconvenience of manually handling the item to be wrapped 2 and preventing the item to be wrapped 2 or the tray 22b from sliding during the wrapping process.

[0031] On the other hand, the lifting member 24 is, for example, a winch made of metal or alloy and adapted to move along a lifting direction R. Specifically, the lifting member 24 is disposed below the support member 22a and connected to the support member 22a through the bottom of the carrying platform 22, and the lifting member 24 and the support member 22a are spaced apart from each other. In this way, when the item to be wrapped 2 or the tray 22b moves to a specific position, the lifting member 24 located below can move along the lifting direction R through the pivoting winch and pass through the gaps between these rollers, thereby abutting the item to be wrapped 2 or the tray 22b, thereby lifting the item to be wrapped 2 or the tray 22b to a specific height to facilitate the wrapping operation. However, in other possible embodiments, the support member 22a and the lifting member 24 can also be combined with each other, that is, the upper surface of the carrying platform 22 can be provided with a complete flat plate, and the flat plate is driven by the lower winch or connecting rod to move along the lifting direction R, which is not a limitation of the present invention.

[0032] In addition, the load-bearing sensor 26 in this embodiment is, for example, a light sensor and is disposed around the load-bearing platform 22 to detect whether the item to be wrapped 2 or the tray 22b has been moved to a specific position, or to detect whether the bottom of the item to be wrapped 2 has tilted or shifted, thereby preventing the wrapping operation from being interrupted.

[0033] Please refer to Figure 4, which is a front view of the wrapping unit in Figure 1. The wrapping unit 30 in this embodiment includes a fixing module 100 and a wrapping module 200. The fixing module 100 is disposed on the frame 10 and includes a fixing pivot 110 and a fixing device 120. The fixing device 120 is connected to the fixing pivot 110 and is adapted to slide relative to the fixing pivot 110 along a fixed direction N. On the other hand, the wrapping module 200 is connected to the fixing module 100 and includes a wrapping pivot 210, a wrapping device 220 and a tension control member 230. The wrapping device 220 is connected to the wrapping pivot 210 and is adapted to slide relative to the wrapping pivot 210 along a film exit direction E. The tension control member 230 is, for example, an electric motor and is connected to the wrapping pivot 210. As shown in Figure 4, the fixing module 100 and the wrapping module 200 are respectively adapted to rotate along a wrapping direction W. In this embodiment, for example, the tension control element 230 drives the fixing module 100 and the wrapping module 200 to rotate synchronously along the wrapping direction W. The wrapping direction W is not perpendicular to the fixing direction N, and the wrapping direction W is also not perpendicular to the film exit direction E. Specifically, in this embodiment, the fixing module 100 and the wrapping module 200 are respectively arranged at opposite ends of a circle enclosed by the wrapping direction W as the rotation axis. The fixing direction N, the film exit direction E, and the wrapping direction W all extend in the vertical direction shown in Figure 4 and are parallel to each other, but the present invention does not limit this. In other possible embodiments, the fixing module 100 and the wrapping module 200 may be positioned at an angle of 60 degrees, 90 degrees, or 120 degrees on the aforementioned circle, and the fixing pivot 110 and the wrapping pivot 210 may extend obliquely according to the size or dimensions of the object to be wrapped 2, thereby causing the fixing direction N and the film exit direction E to be skewed relative to the wrapping direction W. Alternatively, the fixing module 100 and the wrapping module 200 may be positioned at different heights in Figure 4, or have different extension lengths along the radial direction of the aforementioned circle, so that the tension control member 230 can drive the fixing module 100 and the wrapping module 200 individually or in combination with other pivoting devices without causing them to interfere with or collide with each other.

[0034] Please refer to Figures 4 and 5 together, where Figure 5 is a perspective view of the fixing device in Figure 4. Specifically, the fixing device 120 includes a fixing arm 122, which extends generally along the horizontal direction in Figure 4 and includes a fixing end 122a and forms a fixing channel 122b. The fixing channel 122b is located away from the fixing end 122a, and the fixing pivot 110 passes through the fixing channel 122b. Preferably, the fixing device 120 also includes at least one pulley 124. In this embodiment, the number of pulleys 124 is, for example, four, arranged adjacent to the fixing channel 122b, thereby facilitating the sliding of the fixing device 120 relative to the fixing pivot 110 along a fixed direction N when the fixing device 120 is driven.

[0035] On the other hand, the fixing device 120 also includes a fixing member 126, wherein the fixing member 126 is, for example, a metal disc adapted to abut the top of the package 2 and pivotally connected to the fixing end 122a. With this configuration, when the fixing pivot 110 drives the fixing arm 122 to rotate in the wrapping direction W, the fixing member 126 can rotate freely with the fixing end 122a. In other words, even if the fixing arm 122 rotates with the fixing pivot 110 during the wrapping process, the fixing member 126 can remain in its original position and continuously apply pressure to the top of the package 2 to prevent the package 2 from being displaced by the film.

[0036] In addition, in some possible embodiments, the fixing device 120 may also include an elastic element 128, which is, for example, a linear spring and disposed between the fixing end 122a and the fixing member 126. This allows the elastic element 128 to absorb any slight displacement in the fixing direction N during the rotation of the fixing pivot 110 along the wrapping direction W, thereby maintaining the stability of the fixing member 126. In some preferred embodiments, the user may also configure a force sensor to detect the elastic force of the elastic element 128 and confirm that the elastic element 128 maintains an overpressure state during the wrapping process, thereby ensuring that the fixing member 126 applies a fixing force to the object 2 to be wrapped.

[0037] Please refer to Figures 4 and 6 together, where Figure 6 is a perspective view of the film-wrapping device in Figure 4. Specifically, the film-wrapping device 220 of this embodiment includes a film-wrapping body 221, a alignment drive 222, a film supply member 223, a film outlet member 224, and a drive member 225. The film-wrapping body 221 forms a film-wrapping channel 221a, and a film-wrapping pivot member 210 passes through the film-wrapping channel 221a. The alignment drive 222 is, for example, a pulley connected to a motor, disposed on the film-wrapping body 221, and adapted to drive the film-wrapping body 221 to rotate relative to the film-wrapping pivot member 210 along the alignment direction S, and the film outlet direction E is not parallel to the alignment direction S. The film supply member 223 is connected to... The wrapping body 221 is adapted to carry the film 3 that wraps the object 2 to be wrapped. In this embodiment, the film 3 is rolled into a cylindrical shape, and the film supply member 223 is a round rod that passes through the cylindrical film 3 along the film exit direction E. The film exit member 224 is connected to the wrapping body 221 and is spaced apart from the film supply member 223. In this embodiment, it is, for example, a round rod that extends along the film exit direction E. The driving member 225 is connected to the wrapping body 221. In this embodiment, it is, for example, a motor and is arranged between the film supply member 223 and the film exit member 224. The driving member 225 is adapted to guide the film 3 from the film supply member 223 to the film exit member 224. With this configuration, the film 3 unfolded by the film supply member 223 can be guided by the drive member 225 to extend from the film outlet member 224 and cover the surface of the object to be wrapped 2. At the same time, the alignment drive member 222 can adjust the angle of the wrapping body 221 relative to the wrapping pivot member 210 according to the relative position between the object to be wrapped 2, the wrapping device 220 and the film 3, so that the film 3 pulled out by the film outlet member 224 remains perpendicular to the surface of the object to be wrapped 2, thereby preventing the film 3 after wrapping from twisting and covering the object to be wrapped 2 with the maximum area.

[0038] It is worth mentioning that, although this embodiment uses the example of the film-wrapping body 221 rotating relative to the film-wrapping pivot 210 via the alignment drive 222 to achieve the effect of adjusting the orientation of the film body 3, the present invention does not limit this. In other possible embodiments, if the size of the object to be wrapped 2 changes more regularly (e.g., the outer diameter gradually decreases from the bottom to the top), the film-wrapping device 220 can also be tilted and fixed at an angle relative to the film-wrapping pivot 210, which can also achieve the effect of making the phase of the film body 3 correspond to the object to be wrapped 2.

[0039] Furthermore, in some possible embodiments, the wrapping device 220 may also include a film element 226, which is connected to the wrapping body 221. In this embodiment, it is, for example, a round rod extending along the film output direction E, fixed between the film supply element 223 and the film output element 224, and has a smooth surface. This allows the film 3 extending from the film supply element 223 to abut against the surface of the film element 226 to maintain tension, and ensures that the film pulled out by the film output element 224 remains flat, further improving the aesthetics of the wrapped film 3. Alternatively, in other embodiments, the film element 226 may be movably configured on the wrapping body 221. When it is necessary to maintain the tension of the film 3, the film element 226 will abut against the film 3 and flatten it; when it is necessary to reduce the tension of the film 3, the film element 226 can also move to a position separated from the film 3, allowing the film 3 to produce different extension trajectories.

[0040] Please refer to Figure 7, which is a perspective view of the film-collecting unit in Figure 1. In this embodiment, the film-collecting unit 40 is adapted to cut off the film 3 pulled out from the wrapping unit 30 and collect it onto the surface of the object to be wrapped 2. Specifically, the film-collecting unit 40 includes a film-collecting base 42, a film-collecting connector 44, and a film-collecting device 46. The film-collecting connector 44 is pivotally connected to the film-collecting base 42, and the film-collecting device 46 is slidably mounted on the film-collecting connector 44, for example, via a belt slide. Thus, when the user wants to cut off the wrapped film 3, the film-collecting connector 44 can be pivoted to the phase corresponding to the film 3, and the film-collecting device 46 can be driven by the belt slide to abut against the surface of the film 3, thereby cutting off the film 3. It is worth mentioning that in other possible embodiments, the film-collecting unit 40 may not have the film-collecting connector 44, that is, the film-collecting device 46 is only slidably connected to the film-collecting base 42 and does not have the function of pivoting relative to the film-collecting base 42.

[0041] Please refer to Figures 7 and 8 together, where Figure 8 is a perspective view of the film-collecting elements that can be selected for the film-collecting unit in Figure 7. Furthermore, the film-collecting device 46 of this embodiment may include various film-collecting elements for cutting the film 3. For example, the film-collecting device 46 may include at least one heating element 46a, which is, for example, a high-resistance metal strip or sheet. When energized, it heats up based on resistance, thereby melting and adhering the film 3 to the surface of the object to be wrapped 2. Alternatively, the film-collecting device 46 may include an air gun 46b, which can spray high-pressure gas to directly cut the film 3 after the wrapping step is completed. Or, the film-collecting device 46 may include a pair of scissors 46c, which can be configured adjacent to the carrying platform 22. After the wrapping step is completed, the scissors 46c can be driven by a mechanism to close and cut the film 3. In other words, the film-collecting device 46 can cut the film 3 by heat melting, gas cutting, liquid cutting, mechanical shearing and other similar methods. Any film-collecting element that can effectively cut the film 3 and maintain the flatness of the film 3 on the surface of the object to be wrapped 2 is within the scope of protection of this invention.

[0042] The following will describe in detail how the wrapping system 1 of this embodiment wraps the film 3 around the object to be wrapped 2. Please refer to FIG9, which is a partial front view of the wrapping system of FIG1 when the film is wrapped around the object to be wrapped. After the user places the object to be wrapped 2 on the tray 22b, the support member 22a can drive the tray 22b and transport it to a specific position on the carrying platform 22 and then fix it. Afterwards, the fixed arm 122 can slide relative to the fixed pivot 110 along the fixed direction N, so that the fixed member 126 abuts against the top of the object to be wrapped 2 and fixes the object to be wrapped 2 from above. At this time, the wrapping device 220 will detect the relative position of the object to be wrapped 2 and itself. After adjusting the angle of the wrapping body 221 relative to the wrapping pivot 210 by the alignment drive member 222, the film 3 on the film supply member 223 is guided to the film outlet member 224 by the film preparation member 226 through the drive member 225. The fixed pivot 110 and the wrapping pivot 210 will rotate simultaneously along the wrapping direction W, so that the film 3 covers the surface of the object to be wrapped 2 in the circumferential direction.

[0043] When at least one layer of film 3 has been wrapped around a specific height of the item to be wrapped 2, the wrapping device 220 will slide relative to the wrapping pivot 210 along the film exit direction E. Since the wrapping pivot 210 is still rotating along the wrapping direction W at this time, the film 3 will gradually tilt to another height on the item to be wrapped 2. This not only allows it to adhere tightly to different sizes of the item to be wrapped 2 (as shown in Figure 9 where there is only one cardboard box at the top), but also avoids drastic changes in the thickness of the film 3 between different heights. Furthermore, since the alignment direction S of the wrapping body 221 changes according to the tilt angle of the film 3, it can ensure that the film 3 maintains a certain tension and covers the maximum area.

[0044] In addition, when wrapping a smaller portion of the object to be wrapped 2 (as shown in Figure 9, where only a single box-shaped object is placed on top), the tension control member 230 can reduce the rotation speed of the wrapping pivot member 210, thereby adjusting the tension of the membrane 3 to make it more relaxed. At this time, the membrane 3 can act as a rope or strap to fix the small portion. After the membrane 3 wraps around the portion several times in a binding or wrapping manner, the tension control member 230 increases the rotation speed and restores the tension of the membrane 3 to the size that is taut and attached to the surface of the object to be wrapped 2. In other words, by changing the tension of the membrane 3 during the rotation of the wrapping pivot member 210 through the tension control member 230, the membrane 3 can not only tightly cover the surface of the object to be wrapped 2, but also provide a stronger fixing ability in a binding or wrapping manner, thereby adapting to different size changes of the object to be wrapped 2.

[0045] It is worth mentioning that although this embodiment uses the tension control element 230 to increase or decrease the rotation speed of the wrapping pivot 210 to adjust the tension of the membrane 3, the present invention is not limited thereto. For example, the tension control element 230 can also be a motor or controller connected or electrically connected to the wrapping device 220, and adjust the film output speed by controlling the rotation speed of the film output element 224, which can also achieve the effect of controlling the tension of the membrane 3. Alternatively, the tension control element 230 can control the rotation trajectory or rotation radius of the wrapping pivot 210, so that the membrane 3 with a larger travel path per unit time has greater tension, achieving a similar effect.

[0046] After the wrapping pivot 210 rotates a sufficient number of times relative to the object to be wrapped 2 and completes the wrapping operation, the film collection device 46 approaches the end of the film body 3 and cuts off the film body 3 through the aforementioned film collection element (air gun 46b in Figure 9), thus completing the automatic wrapping operation process.

[0047] Please refer to Figure 10, which is a schematic flowchart of an embodiment of the wrapping method of the present invention. The wrapping method of this embodiment is suitable for wrapping the above-mentioned film 3 onto the object to be wrapped 2, and includes the following steps: providing a fixing module, a wrapping module, a film, and an object to be wrapped (step S100); placing the film on a wrapping device of the wrapping module (step S200); fixing the object to be wrapped through the fixing module (step S300); driving a wrapping pivot of the wrapping module to rotate relative to the object to be wrapped (step S400); and driving the film to wrap from the wrapping device onto the object to be wrapped, and the tension of the film changes during the rotation of the wrapping pivot (step S500).
