Detailed ways

Next, the bracket for carrying the optical film roll formed by winding the optical film provided by the present invention and the optical film roll transport vehicle with which the bracket is conveniently transported by the operator will be described below with reference to FIGS. 4 to 8 . It should be noted that Fig. 4 to Fig. 8 are only examples for describing the present utility model in detail, and are not used to limit the protection scope of the present utility model.

<Bracket structure>

Fig.4 (a) has shown the structure of the tray for optical film roll mounting before mounting an optical film roll. A bracket for mounting an optical film roll (hereinafter sometimes referred to as a bracket) has a bracket base; pillars, which are provided at the respective centers of opposite ends of the bracket base and on the upper surface of the bracket base for supporting The winding core (also referred to as the winding shaft) of the optical film roll; two rolling bodies are respectively arranged on the upper part of each support in a rotatable manner around the shaft. Each component of the optical film roll mounting tray will be described in detail below.

[Bracket Base]

As shown in FIG. 4( a ), the bracket base is formed into a picture frame shape with a frame portion so that when the optical film roll is mounted on the bracket, the bracket base can accommodate at least a part of the lower part of the optical film roll. The frame part may be integrally formed, or four separate frame parts may be assembled to form a single body. Here, known methods can be used for integral molding or assembling. It should be noted that the bracket base is not limited to the shape of a picture frame, and may be formed in a plate shape. However, it is preferable that the bracket base be formed in a picture frame shape by the frame part from the viewpoint of suppressing the overall height after mounting the optical film roll.

In addition, considering the transportation of the carrier for mounting the optical film roll, the saving of storage space, etc., the carrier base is preferably formed in a rectangle (an example of a rectangle), but if it is a site where the space is not limited, it can also be formed in a square ( An example of a rectangular shape).

When the bracket base is formed into a picture frame shape, it is preferable that the length of the inner side in the longitudinal direction (direction along the reel) close to the optical film roll is at least longer than the width of the optical film roll (the width of the optical film roll along the reel direction). ) is slightly longer. In this case, when the optical film roll is supported between the two rolling elements on the pillars, the optical film roll can be prevented from contacting the pillars on both sides, and damage to the optical film due to the contact can be prevented.

It should be noted that as long as the optical film roll can be supported without causing damage to the optical film, there are no restrictions on the material, thickness, length, width in the direction perpendicular to the longitudinal direction of the bracket base, or the side frame members when it is composed of a frame portion. The various dimensions of the cross-section etc. are specially limited.

[pillar and two rolling elements]

As shown in FIGS. 4( a ) to ( d ), the pillars are erected on the upper surface of the bracket base so as to face each other at the center of opposite end portions of the bracket base. In the case of a rectangular bracket base, the two ends refer to the two ends along the length direction; in the case of a square bracket base, the two ends refer to any one of the four ends of the square. opposite ends. The strut is preferably formed in a rectangular parallelepiped box shape from a plate-shaped member, and two adjacent rolling elements rotatable via respective shafts are provided on the upper portion thereof. That is, when the two rolling elements are rotatably provided on the upper portion of the pillar, a part of the lower part of the rolling elements is accommodated inside the pillar ( FIG. 4( d )). In addition, the strut may be formed of a block member, and in this case, a concave portion for mounting the two Ro-Ro bodies needs to be formed on the upper surface of the strut.

It should be noted that the material and size of the pillars are not particularly limited. The struts can be fixed to the bracket base by known methods. In addition, the bracket base can be integrally formed with the pillar.

And, as shown in FIGS. 4( a ) to ( d ), the ends of the spool protruding to both sides of the optical film roll are respectively placed on two rolling bodies, and the spool can rotate together with the two rolling bodies. With such a configuration, abrasion due to friction between the spool and the rolling elements can be prevented. In addition, in order to prevent the optical film roll from falling off the bracket when the optical film roll is loaded on the bracket, it is preferable to arrange the two rolling elements so that the shaft center is close to the connecting line of the two rolling body axes, and the connecting line is arranged at The underside of the axis of the reel.

In addition, the bracket base is surrounded by frame members and formed into a picture frame shape, so that a part of the lower part of the roll is stored in the storage space for the optical film roll in the center of the bracket base, so that damage to the optical film can be prevented, and The height of the pillars can be reduced by an amount equivalent to the height in the radial direction of the optical film roll, so that the optical film roll can be loaded in such a way that the center of gravity of the optical film roll is lowered. The overall height is reduced, and as a result, the stability of the mounted optical film roll is improved.

In addition, when the bracket base is formed of a plate-shaped member instead of the picture frame-shaped frame part, in order to prevent the lower part of the optical film roll from contacting the upper surface of the plate-shaped bracket base, it is necessary to make the height of the pillars higher than that of the picture frame. The height of the pillars is high.

In addition, the rolling elements are not particularly limited as long as they can support the reel and rotate together with the reel.

〈Optical film roll transfer vehicle〉

FIG. 5 is a schematic view showing the structure of the optical film roll transport vehicle before the tray on which the optical film roll is mounted as shown in FIG. 4( b ) is placed on the optical film roll transport vehicle. An optical film roll transport vehicle (hereinafter sometimes referred to as a transport vehicle) has: a transport vehicle base, which is provided with wheels on the lower surface of the four corners; a bracket support part, which is provided on the transport vehicle base; on either side of the truck bed. Each structural member of the optical film roll transport vehicle will be described in detail below.

[bracket support part]

The bracket supporting part is preferably formed corresponding to the shape of the bracket for mounting the optical film roll, and its length (length along the reel direction) and width (length in the direction perpendicular to the direction along the reel) are the same as those for mounting the optical film roll. The brackets are about the same. Although there are cases where the tray for mounting an optical film roll is placed on the tray support section from above, the tray for mounting an optical film roll is usually placed on the tray support section by moving laterally. For example, as shown in FIG. 7 and FIG. 8, when moving from the conveyor belt for unloading the tray in the optical film manufacturing equipment or in the optical film roll warehouse to the tray support part of the optical film roll transport vehicle, due to the optical The optical film roll mounting bracket after the film roll is relatively heavy. Therefore, by providing a plurality of balls (an example of a sliding mechanism) on the surface of the bracket supporting part, the lower surface of the optical film roll mounting bracket is slid, thereby The heavy optical film roll mounting bracket can be easily moved. In order to limit the moving direction of the optical film roll mounting bracket caused by sliding, on the side surface of the bracket supporting part along the longitudinal direction (that is, the direction in which the optical film roll mounting bracket slides), a A guide mechanism is erected so that the surface protrudes upward, and this guide mechanism guides the flat side surface of the holder base of the holder for mounting an optical film roll. In addition, the bracket supporting part may be directly detachably mounted on the surface of the carrier base without any parts, but in order to improve the applicability of the optical film roll carrier, the bracket supporting part may be detachably mounted via a height adjustment mechanism. on the base of the truck. Height adjustment mechanism can adopt known mechanism.

In addition, since the optical film roll mounting bracket moves to the bracket support portion by sliding, it is preferable that the lower surface of the optical film roll bracket base be formed flat. In addition, in order to smoothly slide the tray for mounting an optical film roll to the tray supporting portion, it is preferable that the width of the tray supporting portion is substantially the same as the width of the tray for mounting an optical film roll. The "approximately" here may not be the same in the strict sense.

It should be noted that, as shown in FIG. 5 , the bracket support portion is formed in a "day" shape, but it is not limited to this structure, and may also be formed in a picture frame shape without a beam in the center, and may be integrally formed of a plate-shaped member. In addition, the ball and the guide mechanism are not particularly limited as long as they can slide and guide the tray for mounting an optical film roll. Here, the arrangement of the balls on the carriage support portion is not particularly limited as long as the carriage for mounting an optical film roll can be slid. The material of the bracket support portion is not particularly limited as long as it can support the bracket.

In addition, as the sliding mechanism, instead of balls, cylindrical rolling elements can be used.

[Pallet truck base]

The wheels arranged on the lower surface of the truck base are preferably universal wheels that can rotate in all directions. In addition, a brake device (an example of a brake) may be provided on the truck bed in consideration of the movement of the truck when the bracket slides laterally to the bracket support portion. Brake device can be provided separately, also can adopt the wheel with braking function. The brake device that is provided separately can adopt known mechanism.

In addition, the shape, size, material, etc. of the truck base are not particularly limited. For example, the carrier base may be formed in the shape of a picture frame as shown in the shape of the bracket for mounting the optical film roll shown in FIG. type. In addition, when viewed from above, the truck bed may have an outer shape that is substantially the same size as the bracket support portion, or may be slightly larger than the bracket support portion.

In addition, the optical film roll transport vehicle may also have a "U"-shaped bracket fall-off prevention mechanism as shown in FIG. 6(b). After the tray loaded with the optical film roll is placed on the tray support section, the tray may slip freely on the tray support section during the transportation process, so the tray is clamped by the mechanism for preventing the tray from falling off. The frame and the bracket support part can fix the two. The shape of the bracket fall-off preventing mechanism is not limited to the "U" shape. For example, it could be a "C" shape. In addition, not only a clamping method but also a locking method in which the bracket and the bracket support portion are locked to each other to prevent the bracket from falling is also conceivable. The locking mechanism employed in this locking method is also an example of the mechanism for preventing the bracket from coming off. This locking mechanism can adopt known mechanism.

[handle]

The handle is used for operators to carry the optical film roll by pushing or pulling by hand, and there is no limitation on its shape, arrangement position and material. In FIG. 5, the handle is mounted on the side of the truck bed in the lengthwise direction (in the direction of the reel), but it may also be mounted on other sides. For example, as an arrangement position, the handle may be detachably attached to either side of the truck bed, or may be detachably attached to the upper surface or the bottom surface.

<Operation status on site>

The film roll carrier is preliminarily positioned adjacent to one end of the conveyor belt, and has, as described above, a bracket support portion whose height is adjusted to be the same as that of the conveyor belt. The surface of the part is mounted with balls. At this time, since the guide mechanism is provided on the side surface of the tray support portion, the tray for mounting an optical film roll can be accurately and smoothly placed on the tray support portion.

In addition, after the optical film roll loading tray on which the optical film roll is placed is moved to the optical film roll transport vehicle, the operator can freely move the optical film roll transport vehicle by hand because a mechanism for preventing the tray from falling off is installed. When it is necessary to temporarily stop during the transportation, the brake function of the wheels can be used or the brake can be activated to stop.

As shown in FIG. 8 , the operator pushes the optical film roll carrier on which the optical film roll mounting bracket is placed, and transports it to the optical film roll inlet of the next optical film manufacturing equipment, and places the optical film roll in the same state as the optical film roll. Carry in the position adjacent to the entrance, then remove the bracket fall-off prevention mechanism, and move it by hand to a conveying mechanism such as a conveyor belt that is installed at the same height as the bracket support part.

In addition, as shown in FIG. 8 , when the optical film roll mounting tray on which the optical film roll is placed is carried out from the optical film roll warehouse, the height is adjusted to be equal to the height of the conveying mechanism such as a conveyor belt. The optical film roll transport vehicle of the carriage support section is adjacent to the optical film roll warehouse, and the optical film roll loading tray is manually or automatically moved to the optical film roll transport vehicle.

It should be noted that, in the above-mentioned embodiments, as a countermeasure to prevent the optical film roll from falling off the bracket, it has been described, for example, that the axis of the reel is close to the connecting line of the axes of the two rolling elements, so that the two rolling elements are connected. The line is arranged on the lower side of the axis of the reel, but as shown in Figure 9(a)-(c), it is also possible to prevent the optical film roll from falling off the bracket by further providing two optical film roll fall-off prevention covers. As shown in Figure 9(b), the cover body for preventing optical film rolls from falling off includes: an upper cover main body, which surrounds the reel, and is formed in a "U" shape in a plan view; The central part of the side surface protrudes downward and is formed. By inserting the insertion part of the cover body for preventing the optical film roll from falling off into the opening formed by matching the shape of the insertion part in the center of the side part of the upper surface of the support and opposite to the reel, the cover main body surrounds the reel, thereby preventing the optical film roll from falling off. The roll of film is detached from the support of the carriage. Here, it is preferable that the optical film roll detachment preventing cover is formed of a single plate-shaped steel plate having a predetermined thickness. In addition, the shape of the optical film roll detachment preventing cover is not limited to the shape shown in FIG. 9( b ).

The above embodiments are only specific implementations of the present utility model, and the protection scope of the present utility model is not limited thereto. Changes or substitutions that are easily conceivable by those skilled in the art within the technical scope disclosed in the utility model all fall into the protection scope of the utility model.
