Description

  The present invention relates to a film carrying platform used for supporting a roll in which a wide film as a material such as a polarizing film is wound around a winding core in a suspended state at both left and right ends of the winding core.

  A film such as a polarizing film is used in the liquid crystal display, and the manufacturing of the polarizing film is performed by receiving a raw material film wound around a tubular metal winding core. Therefore, it is necessary to convey the raw material film wound around the winding core from the raw material film manufacturing process to the polarizing film manufacturing process without causing scratches or deformation. Conventionally, studies have been made on a carrier for carrying a film while supporting it in a suspended state. However, in recent years, liquid crystal displays have become larger and less expensive, and the raw material film has become wider and longer. As a result, it has become impossible to adequately cope with the conventional carrier.

  Patent Document 1 discloses an example of a conventional transport gantry (a roll film pallet). This pallet includes a support frame that is long on the left and right sides, and a frame that surrounds the four sides of the support frame. In the center of the upper part of each support base, a support concave surface part for assembling with the pipes at both ends of the roll film is provided, and a support piece for blocking the entrance of the support concave surface part is further provided on the upper part. It is connected. And the plate-shaped member is arrange | positioned on the outer side of this supporting concave-surface part (FIG. 4).

  Also, Patent Document 2 discloses an example of a conventional transport stand (film roll package transport stand). This transportation platform has a structure similar to that of the transportation platform described in Patent Document 1. The fixing member (corresponding to “support piece” in Patent Document 1) is provided with a side plate, and the position of the end surface portion of the core of the film roll package (corresponding to “pipe” in Patent Document 1) is defined. And the fixation to the axial direction of this package is strengthened.

  Further, Patent Document 3 also discloses an example (supporting base) of a conventional transport base. This transfer stand also has a structure similar to the transfer stand described in Patent Documents 1 and 2 above. Then, horseshoe-shaped stoppers in which the left and right end faces of the core material (corresponding to “pipe” in Patent Document 1) abut on the center U-shaped part (corresponding to “supporting concave surface part” in Patent Document 1) Equivalent to the “plate-like member” of Patent Document 1.

  In these transport stands, after the core material of the film roll is inserted into the core material receiving portion, the core material is fixed from above by the core material pressing portion, and the vertical movement of the core material is suppressed, and the core material receiver The movement of the core material in the axial direction is suppressed by fixing both ends of the core material with members provided on the part or the core material pressing part. By restricting the movement of the core material in this way, the vibration of the film roll being conveyed is reduced, and the deformation and damage of the film can be suppressed. However, the more the movement of the core material is restricted, the greater the force applied to the core material itself, and the higher the possibility that the core material will be deformed / damaged. For example, as described in Patent Document 1, it is not possible to sufficiently suppress the vibration of the film roll only by fixing only the lower part of the end face of the core material, but as described in Patent Document 2 and Patent Document 3. In addition, if all or most of the end face of the core material is fixed, damage to the core material may increase.

Further, in the second aspect of the present invention, as shown in FIG. 7, the core material movement prevention plate 9 is a pair of left and right plates, there is no bottom surface corresponding to 9a in FIG. Similar to FIG. 5, it protrudes from the side portion 7 b of the core material receiving portion. In the present invention, the core material end of the film roll is firmly fixed by the core material receiving portion 7, the core material pressing portion 8 and the core material movement preventing plate 9.

(Core receiving part and core holding part)
3 and 4 show a core material receiving part 7 for accommodating the film roll core material C (outer diameter Cb, inner diameter Ca) and a core material pressing part 8 for pressing and fixing the film roll core material C from above. Show. 3 shows a concave portion of the U-shaped core material receiving portion 7, and FIG. 4 shows a concave portion of the semicircular core material receiving portion 7. In the present invention, the core material receiving portion 7 preferably has a U-shaped or semicircular recess having a width slightly larger than the outer diameter of the core material to the extent that the film roll core material can be received. At this time, the bottom surface of the core material receiving portion 7 has an arc shape along the outer diameter surface of the film roll core material. Similarly, it is preferable that the lower surface of the core material pressing portion 8 has an arc shape along the outer diameter surface of the film roll core material. After the film roll core material is inserted into the core material receiving portion 7, the film roll core material is pressed by the core material pressing portion 8 from above. As shown in FIG. 2 or 4, the core material pressing portion 8 may be fixed to the upper portion of the core material receiving portion 7 with screws after the core material is inserted, or as shown in FIG. 3. In addition, one side may be pinned rotatably, and the other side may be screwed. As shown in FIGS. 3 and 4, buffer layers 15 made of rubber or flexible synthetic resin are provided on both sides and the bottom surface of the recess of the core material receiving portion 7 for receiving the core material. In addition, it is preferable that a buffer layer 16 made of an elastic member such as rubber is provided on the lower surface of the core pressing portion 8 that is in contact with the film roll.

(Shape of core material movement prevention plate)
As shown in FIG. 1, the core material movement prevention plate 9 is in contact with the outside of the core material receiving portion 7, and the core material movement prevention plate 7 is formed by welding, screws, bolts, nuts, or the like. It is fixed to the receiving part 7. The aspect which shows the specific example of the core material movement prevention board 9 in 1st this invention is shown by FIG. 5 and FIG. As is clear from FIG. 5, the core material movement preventing plate 9 includes a concave portion having a substantially U shape. The width w of the recess preferably covers at least the outer diameter Cb of the core material in order to obtain a sufficient core material movement preventing effect. Thereby, the axial movement of the core material C is prevented. On the other hand, if the width w of the recess is smaller than the diameter wb of the metal rod P inserted into the core material C, the metal rod P may be disturbed when inserted into the core material C. This problem can be avoided if w is larger than the diameter wb, preferably so as not to cover the cavity inside the inner diameter of the core material, and more preferably substantially equal to the inner diameter Ca of the core material. As described above, in the present invention, the core material receiving portion 7 has a U-shape or a semicircular shape. However, as shown in FIG. It protrudes inward from both side portions 7b of the concave portion of the material receiving portion 7. At this time, it is preferable that the protruding side portions 7b are in contact with the end portions of the core material. This reliably prevents the movement of the core material in the film width direction. On the other hand, the aspect which shows the specific example of the core material movement prevention board 9 in 2nd this invention is shown by FIG. In this case, the core material movement preventing plate 9 is a pair of left and right plates, and corresponds to the both side portions 9b of the recess in FIG. As in the first aspect of the present invention, the plate interval w preferably covers at least the outer diameter Cb of the core material in order to obtain a sufficient core material movement preventing effect. Thereby, the axial movement of the core material C is prevented. On the other hand, if the interval w between the plates is smaller than the diameter wb of the metal rod P inserted into the core material C, there is a risk that the metal rod P will be disturbed when inserted into the core material C. This problem can be avoided if w is larger than the diameter wb, preferably so as not to cover the cavity inside the inner diameter of the core material, and more preferably substantially equal to the inner diameter Ca of the core material. As shown in FIG. 7, the left and right plates 9 b of the core material movement prevention plate 9 protrude inward from both side portions 7 b of the recess of the core material receiving portion 7. At this time, it is preferable that the protruding plate 7b is in contact with the end of the core material. This reliably prevents the movement of the core material in the film width direction.

(Bottom of core material movement prevention plate)
In the example shown in FIGS. 5 and 6, the bottom surface 9 a of the concave portion of the core material movement prevention plate 9 is at the same height as the lower outer surface of the core material C held by the core material receiving portion 7. May be below. That is, the bottom surface 9 a of the concave portion of the core material movement prevention plate 9 is the same height as or below the bottom surface 7 a of the concave portion of the core material receiving portion 7. If the bottom surface 9a of the core material movement prevention plate 9 is made higher than the bottom surface 7a of the concave portion of the core material receiving portion 7, the core material end portion may locally hit the bottom surface 9a, causing damage to the core material. If it is at or below the same height, the problem is solved. The prevention of the movement of the core material in the film width direction is achieved by the protrusion of both side portions 9b of the U-shaped recess of the core material movement prevention plate 9 as described above.

(Another example of film carrier)
Another example of the film carrying platform of the present invention is shown in FIGS. In this film transport platform, in addition to the structure of the platform shown in FIGS. 1 and 2, two product stacks (for stacking the platform) are provided on both outer sides of the film roll support frame 3. A side frame 11 is provided. Specifically, each of the side frames 11 includes two support columns 12 provided at the left and right corners of the pallet base 2, and it is desirable that these support columns are connected by a frame 14 for structural reinforcement. Further, the side frame 11 is connected to the column attachment members 13 fixed to the four corners of the pallet base 2 at the respective leg portions of the column 12 constituting the side frame 11, similarly to the film roll support frame 3. 8 and 9, the film roll support frame 3 is positioned inside the product stacking side frame 11 along the length direction and the width direction (front-rear direction) of the pallet base 2. It is preferable.

(Pallet base)
8 and 9, the pallet base 2 includes at least two outer frames 2d along the long side direction, two inner frames 2c parallel to the inside thereof, and a width direction on both sides. The column mounting member 6 for supporting the column 4 constituting the film roll support frame 3 is supported by the inner frame 2c and for supporting the column 12 constituting the side frame 11. The post mounting members 13 are fixed to both sides of the outer frame 2d. In this case, in order to strengthen the gantry, the inner frame 2c and the outer frame 2d may be joined to the outer frame frame 2b, respectively, or the width direction of the base frame so as to connect the outer frame 2d and the inner frame 2c. A plurality of auxiliary frames may be provided in the (front-rear direction).

(Folding structure of film carrier)
As shown in FIG. 8, the column 4 holding the film roll and the column 12 of the side frame 11 are folded inward of the pallet base 2 to reduce the space volume after the film roll is removed. It is configured to be possible. In order to fold so that both the column 4 and the column 12 of the side frame 11 do not overlap, the side frame 11 is folded at a position higher than the film roll support frame 3, and a spacer or the like is set on the frame so that the position can be maintained. It is desirable to do.

(Structure of support mounting member)
As described above, the columns 4 and 12 are foldable, but in order to be foldable, the column 4 is attached to the column mounting member 6, and the column 12 of the side frame 11 is connected to the column mounting member 13 of the side frame. It is attached. An example of a structure in which the column 4 is attached to the column attachment member 6 is shown in FIG. 10, and the column 12 of the side frame 11 can be similarly attached. The column attachment member 6 has a U-shaped cross section, and is provided in a state in which the inner side of the long side of the rectangle is opened so as to form four corners of the rectangle on the pallet base 2. The column 4 is rotatably attached to the column mounting member 6 and is supported by being surrounded by three surfaces. At the same time, the two columns 4 connected by the side frame 5 are integrally formed inside the unsupported pallet base. And is configured to be rotated and folded. In order to make the column 4 rotatable, a hole 20 is formed in the column mounting member 6, and a pin 21 is mounted on the column 4. When the column 4 is fixed at a predetermined position, the column 4 can be rotated about this pin. The hole 20 is a long hole so that the column can be fixed at an appropriate height so that the height of the column 4 can be adjusted according to the film roll diameter. In the above example, the pin 21 is attached to the support column 4 and the elongated hole 20 is provided in the support column attachment member 6. However, this is reversed, and an elongated hole is provided in the support column 4. A pin may be provided.

(Mounting the support mounting member to the pallet base)
FIG. 10 and FIG. 11 show an example in which the column attaching member 6 is attached to the pallet base 2. In this aspect, the pallet base 2 is composed of a frame 2a and a guide frame 2e, and the column mounting member 6 is fitted into a groove 2f formed between the frame 2a and the guide frame 2e of the pallet base 2 without play. The plate-like member 17 that slides together is integrated vertically. The integration method of both is performed by normal methods, such as welding, bolting, and integral molding. The plate member 17 is fastened and fixed to the guide frame 2e by bolts and nuts through a long hole 18 provided in the length direction of the guide frame 2e and a hole 19 provided in the plate member 17. . The column attachment member 6 may be attached to the pallet base 2 by attaching the frame 2a of the pallet base 2 to the frame 2a with a wider width than the examples of FIGS.

(Adjustment of the distance between struts)
As shown in FIG. 10, it is preferable to form a convex portion 22 at the bottom of the column 4 and insert and fix the concave portion 23 formed in the pallet base 2. The pallet base 2 is provided with a plurality of recesses 23 so that the position of the column can be changed according to the width of the film. In the gantry shown in FIG. 10, the column mounting member 6 slides on the inner frame 2c of the pallet base 2, but a slide-dedicated rail may be provided separately from the frame 2c. Further, instead of providing the convex portion 22, it is also possible to adopt a structure in which the support column 4 itself fits directly into a recess or through hole provided in the frame or rail.

(Structure to prevent the column from falling down)
As described above, the column 4 is attached to the column attachment member 6 and is erected, and the film roll is held by the core material receiving portion 7 provided on the side frame 5 that connects the column 4. The weight of the film roll may reach several tons, and a large load is applied to the column 4. In one example of the present invention, in order to make the support column 4 stand upright stably, as shown in FIG. A stopper 25 is provided for fixing the other end of the bar. The bar 24 has a rod shape or a flat plate shape, and one end thereof is rotatably attached to the support column 4 by pinning or the like, and the other end is engaged with and fixed to a stopper 25 on the pallet base. When the support column 4 is folded, the engagement between the bar 24 and the stopper 25 is released. In the present invention, the engagement means a connection / disconnection relationship between the bar 24 and the stopper 25, and the stopper 25 fixes the bar 24 to prevent the upright column 4 from falling inward and necessary. In response, the bar 24 is opened so that it can move freely.

  In an example of the gantry of the present invention, by adopting such a structure, it is possible to prevent the film roll support frame 3 from falling down and rattling between the column attachment member 6 and the pallet base 2. In the present invention, as shown in FIG. 12, the support frame 3, the column mounting member 6, and the pallet base 2 are fixed with bolts, and the convex portion 22 at the bottom of the column 4 and the concave portion of the pallet base 2. 23, the film roll support frame 3 is more completely prevented from falling down and rattling. For this reason, it is easily damaged by slight vibration and backlash during storage and transfer, and is very effective as a carrier for transporting an optical film original roll that has a significant influence on the quality and productivity of the polarizing plate.

  As shown in FIG. 10, when the pallet base 2 is provided with a plurality of recesses 23, the column attachment member 6 and the column 4 move according to the width of the film wound around the film roll. In this case, as shown in FIG. 12, it is preferable that the stopper 25 is also provided so that the position on the pallet base 2 can be changed. In FIG. 12, the stopper 25 is attached to the tip of a plate-like or bar-like support member 25a extending from the column attachment member 6. When the stopper 25 is fixed, the support member 25a is fixed to the pallet base 2 with bolts 25b. . When moving the column 4 and the column mounting member 6, the bolts 25 b are removed, and the column 4 and the column mounting member 6 are slid on the pallet base 2. At this time, the stopper 25 moves following the column 4 and the column attachment member 6 and can be fixed again with the bolt 25b at a predetermined position. Note that the support member 25 a may be attached to the support column 4.

(Folding structure of side frames for stacking)
