The present invention will be described in detail below with reference to the accompanying drawings. It can be understood that, the description related to the drawings is only for the purpose of enumeration and is not intended to limit the present invention. For example, elements in the drawings may not be drawn to actual scale, and / or some details of the elements are omitted. In addition, it is expected that elements, conditions, and features in one embodiment or example can be advantageously incorporated in another embodiment or example, but this is not further enumerated.

Please refer to FIGS. 1A to 1B, which show an exemplary conveying device 1. The conveying device 1 includes a plurality of conveyors 20 and at least one elevation device 30. The conveying line 20 is in a first horizontal direction from an inlet end E1 to an outlet end E2 D1 extends and is sequentially arranged on a second horizontal direction D2 perpendicular to the first horizontal direction D1. The conveying line 20 includes a first conveying line 21 and a second conveying line 22. The first conveying line 21 is used for conveying a first sheet-like object 51, and the second conveying line 22 is used for adjoining the first sheet-like object. The conveyance of a second sheet 52 of 51 is performed. The supporting device 30 is arranged below at least one corresponding conveying line in the conveying line 20. The support device 30 includes a first support device 31. The first support device 31 is located below the first conveying line 21 and supports the first conveying line 21 so that the first conveying line 21 exhibits a height change in a vertical direction D3. Here, the vertical direction D3 is perpendicular to the first horizontal direction D1 and the second horizontal direction D2.

Specifically, according to some embodiments, the conveying device 1 may further include two rollers 10, which are respectively disposed at the inlet end E1 and the outlet end E2, and the conveying line 20 bypasses the two rollers 10, thereby being rolled. The shaft 10 is driven so that the sheet-like article thereon is sent to the outlet end E2. The conveying line 20 may be a belt, a rope, or the like, and is not particularly limited. The sheet-shaped article of the present invention includes, but is not limited to, a final product or a semi-finished product. The sheet-shaped article of the present invention particularly refers to an optical film. The optical film can be a single-layer or multi-layer film, which can be used for gain, alignment, compensation, steering, orthogonal, diffusion, protection, anti-stick, scratch resistance, anti-glare, reflection suppression, high refractive index, etc. The assisted film may be, for example, a polarizing film, a release film, a wide viewing angle film, a brightness enhancement film, a reflective film, a protective film, an alignment liquid crystal film having characteristics such as controlling viewing angle compensation or birefraction, and easy bonding processing. Various surface treatment films such as a film, a hard coating film, an anti-reflection film, an anti-adhesive film, a diffusion film, an anti-glare film, or a combination thereof, but are not limited thereto. In one embodiment, the conveyance speed of the sheet-like object is, for example, 15 to 75 meters / minute (m / min). It can be understood that although not shown in the drawings, a product box may be provided at the exit end E2 for receiving the items being transported. High supporting means 30 such that the corresponding transfer line 20 D1 having an angle [theta] or θ 10 ° ~ 35 ° at the inlet or outlet end E1 and the end E2 first horizontal direction ^', the preferred angle [theta] or ^[theta]' is 20 ° ~ 30 °. In addition, although the first conveying line 21 and the second conveying line 22 shown in the drawings are adjacent to each other, it can be understood that the so-called first conveying line 21 and the second conveying line 22 specifically refer to which conveying line is based on the first A width W and a position of the one-piece object 51 and the second-piece object 52 are determined. For example, when the width W of the first sheet-like article 51 and the second sheet-like article 52 is large, there may be one or more transport lines 20 between the first transport line 21 and the second transport line 22, such as the first Figure 2 shows an example. When a conveying line 20 is only supported by a support device 30, as shown in FIG. 1B, it forms a triangle-like shape with the original horizontal position.

The support device 30 is preferably disposed near the connection 54 formed by the sheet-like object. For example, the first sheet-like article has a width W, and the first support device may be configured in a range of W * (1/3) from the boundary of the first sheet-like article adjacent to the second sheet-like article. The connection 54 corresponds to, for example, the cutting lines of the sheet-like objects. It should be noted that the connection point in the present invention is only used to describe the relationship between two sheet-like objects adjacent to each other and seemingly touching together. The two adjacent sheet-like objects may be caused by, for example, the adhesive layer included therein. Adhesion or other reasons without complete separation, but may not actually be joined together. When a conveying line 20 is only supported by a support device 30, the support device 30 can fall closer to the entrance end E1. For example, in FIGS. 1A and 1B, the first support device 31 is disposed between the entrance end E1 and the intermediate point of the first conveying line 21 in the first horizontal direction D1. According to some embodiments, a support device 30 is a movable and / or height-adjustable device. The position and / or height of the support device 30 can be adjusted according to the size of the sheet-like object or the position of the cutting line.

According to some embodiments, each of the support devices 30 includes a roller 301 and a support mechanism 302 that contact a corresponding one of the conveying lines 20. In some embodiments, an area where the center of the roller 301 contacts the corresponding conveying line 20 may have a smaller diameter to securely fix the conveying line 20 on the roller 301. The roller 301 may be a driving wheel or a passive wheel, and is not particularly limited.

In some cases, the items handled by the conveying device are one or more rows of smaller sheet-like objects formed by cutting a large-area sheet-like object, which may be due to the sheet-like objects. The adhesive layer included in the adhesive force caused by the adhesion to the cutting surface, or other reasons, but not completely separated. With the conveying device including the supporting device 30, a sheet object in a row can be raised as the lower conveying line rises, and another sheet object adjacent to the sheet object is raised. Separated by gravity. Therefore, the use of the conveying device of the present invention can prevent the smaller sheet-like pieces after cutting from sticking or sticking together, so that they are surely separated from each other.
