Description

Conveying device

The present invention relates to a conveying device, and more particularly to a conveying device that provides two different conveying directions.

After the cutting is completed, several optical films will be transported to a centralized place by a conveying device. However, several optical films in the same row fall into the concentrated area substantially at the same time, which increases the probability of collision of these optical films, resulting in impact damage during the dropping process of the optical films. Therefore, proposing a new conveying device to improve the aforementioned problems is one of the directions of the industry in this technical field.

The present invention relates to a conveying device that can improve the aforementioned conventional problems.

An embodiment of the present invention provides a conveying device. The conveying device includes a first conveying module, a second conveying module and a carrier. The first conveying module includes a first conveying mechanism and a first side bar. The first conveying mechanism is arranged on the first side bar and used to provide conveying along a first direction. The second conveying module includes a second conveying mechanism and a second side bar and a third side bar opposite to each other. The second side bar is adjacent to the first side bar, and the second conveying mechanism is disposed on the second side bar and the third side bar. On the rod and used to provide transportation along a second direction, where the first direction intersects the second direction. The carrier is arranged adjacent to the third side rod.

In order to have a better understanding of the above and other aspects of the present invention, the following specific examples are given in conjunction with the accompanying drawings to describe in detail as follows:

Please refer to Figures 1 to 2. Figure 1 shows a top view of the conveying device 100 according to an embodiment of the present invention, and Figure 2 shows the optical film 10 of Figure 1 being conveyed from the first conveying module 110 to the second A schematic diagram of the conveying module 120. The conveying device 100 shown in the figure can be placed on a bearing surface (not shown), and the Z axis in the figure is substantially perpendicular to the bearing surface. The bearing surface is, for example, the ground or floor surface. The several optical film sheets 10 shown are formed by cutting an optical film roll (not shown). The optical film 10 may be, for example, a single-layer or multi-layer film, such as a polarizer, retardation film, brightness enhancement film, or other optical gain, alignment, compensation, steering, orthogonal, diffusion, protection, and anti- Useful diaphragms such as stickiness, scratch resistance, anti-glare, reflection suppression, high refractive index, etc. The material of the optical film 10 can be selected from the group consisting of Triacetate Cellulose (TAC), Polymethylmethacrylate (PMMA), Polyethylene Terephthalate (PET), Polypropylene Polypropylene (PP), Cyclo Olefin Polymer (COP), Polycarbonate (PC), polyester resin, olefin resin, cellulose acetate resin, polycarbonate resin, acrylic resin, polymer Butylene phthalate (polyethylene terephthalate, PET), polyethylene (PE) or polypropylene (Polypropylene, PP), cycloolefin resin or a combination of the above, wherein the polyester resin is, for example, polyethylene terephthalate Ester or polyethylene naphthalate, and the acrylic resin is, for example, polymethyl methacrylate (PMMA).

When the optical film 10 is a polarizer, the material can be a polyvinyl alcohol (PVA) film that absorbs and aligns dichroic pigments or is formed by liquid crystal material mixed with absorbing dye molecules. Polyvinyl alcohol can be formed by saponifying polyvinyl acetate. In some embodiments, polyvinyl acetate may be a monomer of vinyl acetate or a copolymer of vinyl acetate and other monomers. The above-mentioned other monomers may be unsaturated carboxylic acids, olefins, unsaturated sulfonic acids, vinyl ethers, and the like. In other embodiments, the polyvinyl alcohol may be modified polyvinyl alcohol, for example, polyvinyl formaldehyde, polyvinyl acetaldehyde, or polyvinyl butyral modified by aldehydes.

The conveying device 100 includes a first conveying module 110, a second conveying module 120 and at least one carrier 130. The first conveying module 110 includes a first conveying mechanism 111 and a first side bar 112 and a fourth side bar 113 opposite to each other. The fourth side bar 113 and the first side bar 112 are arranged non-parallel. The first conveying mechanism 111 is disposed on the first side bar 112 and the fourth side bar 113, and is used to provide conveying along the first direction S1. As shown in Figure 1, in an embodiment, the first angle A1 between the fourth side bar 113 and the first side bar 112 is, for example, an acute angle, which can be between 15 degrees and 75 degrees, such as 45 degrees. However, the range of the first included angle A1 in the embodiment of the present invention is not limited by this. In another embodiment, the longitudinal direction of the optical film 10 and the conveying direction of the first conveying mechanism 111 have a second included angle A2, which may be between 15 degrees and 75 degrees, such as 45 degrees, but the present invention is implemented In the example, the range of the second included angle A2 is not limited by this.

As shown in FIG. 2, this embodiment is described by taking the short side of the optical film 10 as the falling side falling from the first side rod 112 as an example. In this case, a third angle A3 is formed between the long axis direction of the first side rod 112 and the orthogonal direction of the first direction S1, and a fourth angle A3 is formed between the long side direction of the optical film 10 and the first direction S1 A4, where the third included angle A3 and the fourth included angle A4 are substantially equal. However, the third included angle A3 and the fourth included angle A4 may also be different. For example, the difference between the third included angle A3 and the fourth included angle A4 (ie A3-A4) may be approximately equal to or less than ±15°, preferably approximately equal to or Less than ±10°, more preferably approximately equal to or less than ±5°. On the other hand, in the example where the optical film 10 is changed to fall from the first side rod 112 with the long side, the value of (90°-A3) is approximately equal to the fourth included angle A4, but (90°-A3) and the fourth included angle The difference of A4 (ie (90°-A3-A4)) may also be approximately equal to or less than ±15°, preferably approximately equal to or less than ±10°, and more preferably approximately equal to or less than ±5°.

The second conveying module 120 includes a second conveying mechanism 121 and a second side bar 122 and a third side bar 123 opposite to each other. The second side bar 122 is adjacent to the first side bar 112, and the second conveying mechanism 121 is disposed on the second side bar 122 and the third side bar 123, and is used to provide conveyance along the second direction S2, where the first direction S1 and The second direction S2 intersects. The “intersect” here means that the first direction S1 and the second direction S2 are not parallel. The carrier 130 is disposed adjacent to the third side rod 123. Each optical film 10 is sequentially conveyed by the first conveying mechanism 111 and the second conveying mechanism 121, and is dropped into the corresponding carrier 130 from the second conveying mechanism 121.

In one embodiment, the conveying speed of the first conveying mechanism 111 and the second conveying mechanism 121 is between 10 meters per minute (m/min) and 70 m/min. In an embodiment, the conveying speed of the first conveying mechanism 111 is equal to or less than the conveying speed of the second conveying mechanism 121.

Although not shown, the carrier 130 can be placed on a cart, which can save effort and transport several carriers 130 at a time.

As shown in Figure 1, the first conveying mechanism 111 is used to convey the optical film 10 in the first direction S1. Each optical film 10 has a first side 10e1, and each first side 10e1 is connected to the long axis of the first side rod 112. The directions are substantially parallel, and the extending direction of the first side 10e1 is not perpendicular or parallel to the first direction S1, but may also be parallel or perpendicular. When the optical film 10 is rectangular, the first side 10e1 is, for example, the short side of the optical film 10, but it can also be the long side. As shown in the figure, since the first side bar 112 is an oblique bar (for example, the first side bar 112 is not parallel or perpendicular to the first direction S1), the optical films in the same row are separated from the first side bar 112 Depending on the distance between, the time point at which several optical films in the same row on the first conveying mechanism 111 are conveyed to the second conveying mechanism 121 will also be different. Taking the same row of optical films 10'~10'''' as shown in Figure 1, for example, the distances between the optical films 10'~10'''' and the first side rod 112 are D1'~D1, respectively ''''. Since the distances D1'~D1'’’’ are different, the time for the optical films D1’~D1’’’’ of the same row to be transported to the second transport mechanism 121 will also be different. For example, taking the distances D1', D1'', D1''' and D1'''' from short to long, the order in which the optical film is conveyed from the first conveying mechanism 111 to the second conveying mechanism 121 is optical Diaphragm 10', 10'', 10''' and 10''''.

As shown in Figure 1, each optical film 10 has a center of gravity 10c, and the length of the connecting line L1 of the several centers of gravity 10c of the several optical films 10'~10"" in the same row and the length of the first side rod 112 The axis directions are not parallel, but they can also be substantially parallel. The aforementioned distance D1'~D1'''' is, for example, the distance between the center of gravity 10c of the optical film 10 and the first side rod 112. In an embodiment, the first distance d1 between the centers of gravity 10c of any two adjacent optical films 10 is substantially the same, where the first distance d1 is, for example, a dimension along a direction perpendicular to the long side of the optical film 10.

The distances between the plurality of optical films 10 and the third side rod 123 are different and gradually change. For example, as shown in Figure 2, the several optical films conveyed from the first conveying mechanism 111 to the second conveying mechanism 121 are optical films 10'~10"" in order, so the optical films The distance between 10'~10'''' and the third side rod 123 of the second conveying module is also different. For example, when these optical films 10'-10"" are sequentially conveyed to the second conveying mechanism 121, the optical films 10'-10"" on the second conveying mechanism 121 are separated from each other by the first The distances of the three-sided rods 123 are D2'~D2””, and the distance from the smallest to the largest is D2'~D2””. In this way, the order in which the optical films 10'~10"" on the second conveying mechanism 121 fall into the carrier 130 are optical films 10', 10", 10"' and 10' '''. In an embodiment, the second distance d2 between the centers of gravity 10c of any two adjacent optical films 10 is substantially the same, where the second distance d2 is, for example, a dimension along a direction perpendicular to the long side of the optical film 10. In an embodiment, the second distance d2 is greater than the first distance d1, so that the distance between any two adjacent optical films 10 can be opened to reduce the probability of collision between two adjacent optical films. In another embodiment, d2/d1 may be between 2 and 1.1.

As shown in FIG. 2, the second conveying mechanism 121 is used to convey the optical film 10 in the second direction S2. The second direction S2 is different from the first direction S1, so that the direction in which the optical film 10 is conveyed from the first conveying mechanism 111 to the second conveying mechanism 121 can be changed. As shown in the figure, in the optical film 10 on the second conveying mechanism 121, the first side 10e1 of each optical film 10 and the long axis direction of the third side rod 123 are substantially parallel, and the first side 10e1 extends The direction is substantially perpendicular to the second direction S2.

In one embodiment, please refer to FIG. 3, which shows a side view of the first conveying module 110 and the second conveying module 120 of Fig. 1. The optical film 10 after cutting may be slightly deformed to assume a warped shape. For example, the middle may protrude upward relative to the two sides, or the middle may be concave downward relative to the two sides, or it may be flush. In order to overcome the above-mentioned problems, the embodiment of the present invention may further set the position of the second conveying mechanism 121 to be lower than that of the first conveying mechanism 111. For example, the position of the second side bar 122 of the second conveying module 120 is lower than that of the first conveying module 110 The first side rod 112 enables the opposite ends of the second conveying mechanism 121 and the first conveying mechanism 111 to be partially overlapped along the Z-axis. In this way, it can be ensured that the optical film 10 can completely fall on the second conveying mechanism 121 after it leaves the first conveying mechanism 111 (if the second conveying mechanism 121 and the first conveying mechanism 111 do not overlap along the Z-axis, it will As a result, the distance between the second conveying mechanism 121 and the first conveying mechanism 111 along the X-axis is too large, which in turn may cause the optical film 10 to leave between the first conveying mechanism 111 and the second conveying mechanism 121 after it leaves the first conveying mechanism 111. The interval drops to the bearing surface). In an embodiment, at least a part of the second side bar 122 of the second conveying module 120 may be located directly below the first conveying module 110.

Please refer to FIG. 4, which illustrates a schematic diagram of the optical film 10 of FIG. 2 falling from the second conveying module 120 into the carrier 130. The carriers 130 are used to carry the optical films 10 dropped from the third side rod 123 of the second conveying module 120. Taking the optical film 10'~10'''' as an example, the distance between the optical film 10'~10'''' and the third side rod 123 is D2'~D2'' in order from short to long. Therefore, the optical films that fall into the carrier 130 are also optical films 10'-10"" in order. In other words, the optical films 10'-10'''' leave the second conveying module 120 at different time points, and then fall into the corresponding carrier 130 in sequence. Since the optical film 10'~10"" falls from the second conveying module 120 at different time points, that is, the optical film 10'~10"" does not fall at the same time, the optical film 10 can be reduced or even avoided. '~10''''The probability of hitting each other when falling. In addition, similar to the foregoing, since the second distance d2 in FIG. 4 is greater than the first distance d1, the distance between any two adjacent optical films 10 can be opened to reduce the probability of collision between two adjacent optical films.

As shown in Figure 4, the position of each carrier 130 is located on the path of the corresponding optical film 10 (for example, the same row of optical films 10 arranged in the second direction S2) along the path of the second direction S2, so as to receive from the third The optical films 10 in the same row (for example, arranged along the second direction S2) where the side bars 123 fall.

Please refer to FIG. 5, which shows a process diagram of the optical film 10 of FIG. 4 falling into the carrier 130. As shown in the figure, each bearing member 130 includes a bearing plate 131, a first bearing plate 132, and a second bearing plate 133. The bearing plate 131 has a bearing surface 131u, and the first bearing plate 132, the second bearing plate 133 and the The bearing surface 131u meets at a bearing point P1.

As shown in FIGS. 1 and 5, the edge 131e of the carrier plate 131 is located on the path of the optical film 10 along the second direction S2. When the optical film 10 is dropped from the third side rod 123, the optical film 10 will first contact the edge 131e of the carrying plate 131 and the center of gravity 10c will be above the carrying surface 131u. Therefore, the gravity of the optical film 10 will affect the optical film 10 drives toward the supporting surface 131u, so that the optical film 10 falls on the supporting surface 131u by its own weight.

As shown in Figure 5, the bearing point P1 is the lowest point of the bearing surface 131u. In this way, after each optical film 10 dropped from the third side rod 123 falls on the bearing surface 131u, the corner point P2 of the optical film 10 will automatically align to the supporting point P1, and the first side of the optical film 10 10e1 and the second side 10e2 are aligned with the first supporting plate 132 and the second supporting plate 133, respectively.

6 and 4 are schematic diagrams of the first conveying element 1111 in FIG. 1. The first conveying mechanism 111 includes a plurality of first conveying elements 1111 (only one is shown in FIG. 6), and the rotation axis direction AX1 of each first conveying element 1111 is substantially perpendicular to the first direction S1. Each first conveying element 1111 includes two bases 1111a, two pulleys 1111b, two pivot shafts 1111c, and belts 1111d. The two bases 1111a are respectively arranged on the first side rod 112 and the fourth side rod 113, and the pulley 1111b passes through the pivot shaft. The 1111c is rotatably arranged on the corresponding base 1111a, and the belt 1111d is sleeved on the outer peripheral surface of the two pulleys 1111b to be driven by the pulley 1111b. When the pulley 1111b rotates (for example, driven by a driver (not shown)), the belt 1111d can be driven to transport the optical film 10 (not shown in FIG. 6) on it.

As shown in FIGS. 6 and 4, in this embodiment, each first conveying element 1111 is independently arranged on the first side bar 112 and the fourth side bar 113. At least one of all the first conveying elements 1111 is driven by the same driver (such as a motor). As shown in the figure, the first direction S1 is substantially perpendicular to the axis direction AX1 of the pivot axis 1111c of each first conveying element 1111. As shown in Figure 4, since the first side bar 112 and the fourth side bar 113 are arranged non-parallel, the lengths of the first conveying elements 1111 arranged on the first side bar 112 and the fourth side bar 113 are different For example, the lengths of the belts 1111d of the first conveying elements 1111 (for example, along the X axis) are different.

In addition, as shown in FIGS. 6 and 4, the second conveying mechanism 121 may include at least one second conveying element 1211, and the second conveying element 1211 has the same or similar structure as the first conveying element 1111. For example, each second conveying element 1211 also includes two bases, two pulleys, two pivot shafts, and a belt, which are respectively the same as or similar to the two bases 1111a, two pulleys 1111b, and two pivot shafts 1111c of the aforementioned first conveying element 1111. And belt 1111d, the connection relationship of the base, pulley, pivot shaft and belt of each second conveying element 1211 is also the same or similar to the connection of the base 1111a, pulley 1111b, pivot shaft 1111c and belt 1111d of the first conveying element 1111 relationship. As shown in FIG. 4, the two pivot directions AX1 of the two pivot axes of each second conveying element 1211 are substantially parallel to the second side bar 122 and the third side bar 123, respectively.

In summary, although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Those who have ordinary knowledge in the technical field to which the present invention belongs can make various changes and modifications without departing from the spirit and scope of the present invention.
