Description

  The present invention supports a roll body formed by winding a sheet-like long article such as a polyvinyl alcohol film for forming a plastic film, in particular a polarizing film, etc. around a core material at both left and right ends of the core material, The present invention relates to a roll support for storing or transporting the body in a horizontal state.

  Conventionally, large-size original film used for manufacturing final products such as polyvinyl alcohol film made of polyvinyl alcohol resin and polarizing film made of polyvinyl alcohol film prevents damage or deformation during storage or transportation. Therefore, after winding around a core material (core tube) wider than this film to form a roll body (long roll), both end portions of the core material projecting to the left and right of the roll body are substantially U-shaped or It is supported or supported by a pair of left and right mounting tables provided with a core material receiving portion such as a substantially V shape, and is stored or transported in a state where the roll body is horizontally mounted (a state where the central film portion is floated in the air).

  As such a roll support, for example, a roll support shown in Patent Document 1 is known. This is provided with a mounting table (A) and a mounting table (B) having different heights, and when the film is shipped, the roll body is supported at a high position by the mounting table (A). When returning the support table, the mounting table (A) is folded and the lower mounting table (B) is projected upward from the upper surface of the base, and the film wound on the mounting table (B) is empty. In order to prevent the core material from dropping, the core material and the mounting table (B) are bundled with a rubber band or the like and fixed. According to this roll support base, the entire roll support base at the time of return can be made compact, and damage to the core material and the like due to impact during transportation can be prevented. An example of a roll support that draws such a flow is shown in FIGS.

  FIG. 5 is a perspective view when the conventional roll support base is returned, and FIG. 6 is an explanatory view showing a use state of the roll support base. That is, this roll support base is formed by connecting a hollow rectangular column frame and a base 1 having a substantially rectangular shape in plan view, and a roll body 6 formed by winding a film around a core material 3 in a horizontal state. A pair of mounting tables (A) 2 (folded in FIG. 5) supported at a predetermined height, and a pair of mounting tables (B) that support both ends of the core material 3 in which the film is empty. 4 and a collapsible core material mounting table 7 that holds the core material 3 in a horizontally mounted state.

  When the film is shipped, as shown in the upper part of FIG. 6, the roll support base stands the above-mentioned mounting base (A) 2, and the roll in a state of being horizontally placed on the standing mounting base (A) 2. When the core 6 is supported and the core material 3 is returned, the mounting table (A) 2 is folded in a direction facing each other, and the core material mounting table 7 is protruded, as shown in the lower part of FIG. As shown in FIG. 5, both the end surfaces of the core material 3 are covered with a pair of mounting tables (B) 4 so that the core material 3 extends in the longitudinal direction. The movement is suppressed. When the core material 3 is returned, the core material 3 and the core material mounting table 7 are bundled and fixed with a rubber band 11 in order to prevent the core material 3 from dropping due to an impact during transportation.

JP 2010-265024 A

  As described above, the roll support base that uses two types of mounting tables having different heights has an advantage that the roll support base can be made compact at the time of return, but each time the return is made, the core support base 7 is raised. It takes time and effort. Further, when transporting an empty core material 3, the core material 3 is only fixed to the core material mounting table 7 by the rubber band 11. As a result, the core material 3 jumps up, and the core material 3 and the core material mounting table 7 may be deformed or damaged. Moreover, since a pair of mounting bases (B) are provided so as to cover both end surfaces of the core material 3, an arm such as a crane can be inserted into each end opening of the core material 3 in this state. Therefore, there is a problem that it is difficult to lift the core material 3. In addition, since the rubber band 11 used for fixing the core material 3 is likely to deteriorate, there is also a problem that the core material 3 may drop off during work or transportation. Therefore, there is a strong demand for improvement.

  The present invention has been made in view of such circumstances. The core material 3 can be firmly fixed only by a simple operation, and even if an excessive impact is applied during transportation, the core material is affected by the impact. The purpose is to provide an easy-to-use roll support base in which 3 does not move.

In order to achieve the above-mentioned object, the roll support of the present invention has a predetermined shape in a state in which a roll body formed by winding a substantially rectangular base and a film around a core material having both ends formed into a cylindrical shape is horizontally mounted. And a pair of support tables (A) that can be raised and lowered, and a pair that supports both ends of the mounting base (A) at a position lower than the support position by the mounting table (A). And the pair of mounting tables (B) are provided in a standing posture on the base, and each of the mounting tables (B) rises from the base, and the rising parts Each of the mounting bases (B) including a core material mounting portion provided horizontally, a stopper that suppresses the movement of the core material in the longitudinal direction, and a holding portion that suppresses the movement of the core material in the circumferential direction. the standing part of) has a body portion and a clamp portion mounted rotatably on the main body, the rotation of the clamping portion The core material is fixed on the mounting table (B) by inserting the tip of the clamp portion into the end opening of the core material that is horizontally mounted on the mounting table (B), and the clamp unit The gist of the roll support is provided with core material holding means configured so that the core material is released from being fixed by returning the position to the initial position .

That is, the present inventors have conducted research in order to protect the core material in the roll support that is returned after the film is used. As a result, used as both ends as the core material is formed into a cylindrical shape, a pair of second mounting base for supporting the core material at a position lower than the mounting table (A) of (B), each upright in part, by fixing the both ends of the core member which is laterally placed on the mounting table (B) to hold the support state of the core material, when removing the core material, configured to release the fixed When a special core material holding means is provided, as in the past, the roll support table is provided with a core material mounting table that protrudes upward from the upper surface of the base only when the roll body is not loaded, or for fixing the core material. It has been found that the core material can be firmly fixed while using a simple structure without using a rubber band, and the present invention has been achieved.

As described above , the roll support base of the present invention uses a pair of mounting bases that are formed in a cylindrical shape at both ends as the core material and are supported at a position lower than the support position by the pair of mounting bases (A). A special core material that can hold the supporting state of the core material by fixing both ends of the core material horizontally mounted on the mounting table (B) to the mounting table (B) side in each standing part of (B) Holding means is provided. For this reason, as in the prior art, the structure of the base is complicated, such as providing a mounting base for core material that protrudes upward from the upper surface of the base only when the roll body is not loaded, or a rubber band is used to fix the core material. There is no need to use it, and the core material can be securely fixed to the mounting table (B), and this fixing can be released. Since the pair of mounting tables (A) are provided so that they can be tilted up and down, when the roll support table is returned, the roll support table can be laid down and folded to make the roll support table compact. Space is being planned.

That is , as the core material, one having both ends formed in a cylindrical shape is used, and the core material holding means provided on each standing portion of the mounting table (B) is provided on the base or the mounting table (B). An end portion opening of the core member that has a fixed main body portion and a clamp portion that is rotatably attached to the main body portion, and that is pivoted on the mounting table (B). to, by entering the distal end of the clamping portion, the core member is fixed on the mounting table (B), by returning the clamp portion to the initial position, as fixed in the core material is unconfigured because it is, without the large scale of the core holding means can disposed space. Moreover, since it is simple structure, since a core material can be reliably and simply fixed on a mounting base (B), it is convenient.

  Further, when the pivoting posture of the clamp part is fixed or released by a lock lever that is pivotally attached to the main body part, the core material and the mounting table can be easily operated. (B) can be fixed and released more reliably, and operability is good.

  Furthermore, when a plurality of roll bodies having different lengths are prepared, and the mounting positions of the mounting table (A) and the mounting table (B) can be changed according to the length of the roll body, Films of various sizes can be transported and stored simply by changing the mounting position of the mounting table (A) and mounting table (B) according to the size (width) of the film or core material. For this reason, it is not necessary to prepare and store the roll support bases as many as the number of types (widths) of the film or the core material, and the cost can be reduced and the space can be saved.

  Next, an embodiment for carrying out the present invention will be described.

  FIG. 1 is a perspective view showing a state when a roll support base according to an embodiment of the present invention is returned. That is, this roll support base is for supporting the roll body 6 formed by winding the film around the core material 3 or the core material 3 in which the film is emptied, and is configured by connecting hollow prismatic frames. A substantially rectangular base 1 in a plan view, a pair of mounting tables (A) 2 that support the roll body 6 in a state of being horizontally mounted, and a support of the core 3 in a state of being horizontally mounted A pair of mounting tables (B) 4, core material holding means 5 provided in the vicinity of the mounting table (B) 4, and four support columns 8 provided at the four corners of the base 1. ing.

  More specifically, the base 1 is formed by connecting hollow square members made of metal such as iron, and as shown in FIG. 1, two long long side frames 1a constituting the long side, The two short short side frames 1b constituting the short side are formed in a substantially rectangular shape in plan view.

  And inside each long side frame 1a of the said base 1, while reinforcing the said base 1, the two inner side frames 1c used as the attachment part of the mounting base (A) 2 are the long side frame 1a. It is provided in parallel.

  The pair of mounting tables (A) 2 are attached to the inner frame 1c so as to be able to rise and fall in directions facing each other. When these are raised, the roll body 6 can be supported at a predetermined height, When returning the table, they are laid down and folded (see the upper part of FIG. 6).

  In addition, at the four corners of the base 1, four support columns 8 that can be raised and lowered are provided, and auxiliary frames 8 a that serve as guides for the support columns 8 when the support columns 8 stand. That is, each support column 8 stands and falls along the longitudinal direction of the base 1 with the pivoting portion 8b as a fulcrum, and when the support column 8 stands, its base portion is fitted into the auxiliary frame 8a. The standing posture is maintained. Further, as shown in FIG. 1, the support column 8 can be folded inward along the long side frame 1 a of the base 1, and accordingly, the auxiliary frame 8 a protrudes high from the base 1. ing. And the leg part 10 fitted with the upper end of each support | pillar 8 of the other roll support stand of the same shape or the upper end of each auxiliary frame 8a is provided in the lower end of the said auxiliary | assistant frame 8a, respectively. Accordingly, by fitting the legs 10 with the support 8 or the auxiliary frame 8a of another roll support base, the roll support bases can be multi-staged in a state where the support post 8 is raised or the support post 8 is folded. Can be stacked.

  The two short side frames 1b constituting the short side of the base 1 are provided with a pair of mounting tables (B) 4 for supporting the core material 3 in a horizontally mounted state. This mounting table (B) 4 is the above described in a state where the above-mentioned mounting table (A) 2 is folded and the height of the roll support table is lowered at the same time as the support column 8 is folded and folded when the roll support table is returned. This is for supporting the core material 3 at a position lower than the mounting base (A) 2.

  As shown in FIGS. 2 (a) and 2 (b), the mounting table (B) 4 is provided on a standing part 4a that rises from the short side frame 1b of the base 1, and is provided horizontally on the standing part 4a. The mounting portion 4 b of the core material 3, a stopper 4 c that suppresses the movement of the core material 3 in the longitudinal direction, and a holding portion 4 d that suppresses the movement of the core material 3 in the circumferential direction are provided. A rubber sheet 13 is disposed on the placement portion 4b in order to prevent the core material 3 from slipping and shock from the outside.

  Then, on the side of the mounting table (B) 4 (on the side opposite to the side supporting the core material 3), when supporting the core material 3, core material holding means 5 for fixing the supporting state is provided. Is provided. As shown in FIGS. 2 (a) and 2 (b), the main body 5a of the core material holding means 5 has two sheets fixed to the side surface 4e of the standing part 4a of the mounting table (B) 4. It consists of a pair of plates. A substantially L-shaped clamp portion 5b is attached to the main body portion 5a via an engagement pin 5g so as to be rotatable and slidable. That is, the side surface of the clamp part 5b is provided with a long hole 5f, and the engaging pin 5g is inserted through the long hole 5f, so that the clamp part 5b is vertically moved along the long hole 5f. And can rotate around the engaging pin 5d. Further, an engaging pin 5d is horizontally fixed to the upper portion of the vertical side portion of the clamp portion 5b, and an engagement notch is formed at the upper end portion of each plate on which the main body portion 5a is opposed. 5c is provided. Then, when the clamp portion 5b is rotated and slid to fall in the upright posture (indicated by a chain line 5b 'in FIG. 2A) and dropped down on the stone, the engagement pin 5d is engaged. The clamp portion 5b is held in an upright posture by engaging with the notch 5c. Therefore, the lower end opening of the core member 3 is sandwiched and fixed between the elastic member 14 provided at the tip of the lateral side of the clamp portion 5b and the placement portion 4b.

  In addition, a lock lever 12 is provided inside the clamp portion 5b to prevent the clamp portion 5b from rotating and to ensure that the core member 3 is fixed to the mounting table (B) 4. The lock lever 12 has a substantially L-shaped shape, and one end side (rotating portion 12a) of the lock lever 12 is rotatably mounted using the engaging pin 5d which is the rotation center of the clamp portion 5b. It has been. The other end portion 12c on the other end side of the lock lever 12 is free and protrudes outward from a long hole 5e extending in the vertical direction at the center of the vertical side portion of the clamp portion 5b.

  Since the lower end of the rotating portion 12a of the lock lever 12 is formed in a special arc shape, as shown in FIG. 2 (a), an engagement pin for the clamp portion 5b is formed in the notch 5c of the main body portion 5a. 5d is engaged and the clamp portion 5b is in an upright posture, and the other end portion 12c that is free of the lock lever 12 is pushed downward, and the lock lever 12 is pushed inward. Then, the lower end portion of the rotating portion 12a enters below the lower end of the clamp portion 5b, and the bent portion 12b cut into a V shape in plan view engages with the lower end edge of the elongated hole 5e of the clamp portion 5b. At this time, the lock lever 12 is pushed downward due to the weight of the clamp portion 5b, and the free other end portion 12c of the lock lever 12 tries to enter inside as shown by a thick arrow in FIG. Therefore, the inward force as a whole works and it does not move easily. Therefore, the fixing of the core material 3 to the mounting table (B) 4 can be reliably locked.

  In order to release the lock and take out the core material 3 from the mounting table (B) 4 as described above, as shown by the thick arrow in FIG. 12c is pulled up while resisting the weight of the clamp part 5b, and the engagement between the bent part 12b of the lock lever 12 and the elongated hole 5e of the clamp part 5b is released. Then, the entire clamp portion 5b is lifted upward as indicated by the arrow, and the engagement of the notch 5c of the main body portion 5a and the engaging pin 5d of the clamp portion 5b is released. As a result, as shown in FIG. 3 (b), the clamp portion 5b is rotated around the engaging pin 5g and tilted forward (rightward in the figure), so that the core 3 It can be released. Therefore, in this state, the core material 3 can be taken out from the mounting table (B) 4 described above.

  According to the roll support base, as described above, the horizontal core material 3 is fixed to the vicinity of the mounting table (B) 4 on which the empty core material 3 is placed, and the core material 3 is fixed. When removing the core member, a core member holding means 5 is provided so as to release the fixation. For this reason, it is possible to provide a core material mounting table that protrudes upward from the upper surface of the base 1 only when the roll body 6 is not loaded, and to fix the core material 3 to the core material 3 with a rubber band 11 as in the prior art. It becomes unnecessary. Therefore, the core material 3 can be reliably fixed to the mounting table (B) 4 with a simple operation, and the fixing can be released, which is convenient.

  In particular, in this example, as the core material 3, the one having both ends formed in a cylindrical shape is used, and the core material holding means 5 is fixed to the body part 5 a fixed to the mounting table (B) 4. Since the clamp portion 5b is rotatably attached to the main body portion 5a, the opening of the core member 3 that is horizontally mounted on the mounting table (B) 4 by rotating the clamp portion 5b. The tip of the clamp portion 5b can be inserted into the end portion, and the core material 3 can be fixed to the mounting table (B) 4 described above. At that time, since the elastic member 14 made of rubber is provided at the tip of the lateral side portion of the clamp portion 5b, the holding performance of the core material 3 is enhanced and the impact can be more absorbed from the outside. The material 3 is further protected. Then, by returning the clamp portion 5b to the initial position, the fixing of the core material 3 can be easily released. For this reason, the core material holding means 5 does not become large and space is saved.

  In addition, since the support column 8 is provided so that it can be tilted up and down, and the pair of mounting tables (A) are provided so as to be able to be tilted up and down, the folding support column 8 and the mounting table (A) can be folded. By supporting the core material 3 on the mounting table (B), the roll support table at the time of return can be made compact, and further space saving is achieved.

  And since the rotation posture of the clamp part 5b is fixed or released by the lock lever 12 attached to the main body part at the base side, the operability is particularly good, and the core material 3 and the mounting table (B) 4 can be fixed and released more reliably.

Moreover , in the said embodiment, the said core material 3 uses what was formed in the cylindrical shape at both ends, and the said core material holding | maintenance means 5 is the main-body part 5a fixed to the said mounting base (B) 4, , due to the use of one having a clamp portion 5b mounted rotatably on the main body portion 5a, with simple structure, Ru can reliably hold the core 3.

  In the above embodiment, rubber is provided as the elastic member 14 at the tip of the lateral side portion of the clamp portion 5b. However, the present invention is not limited to this, and other highly elastic members can also be used. Further, the elastic member 14 is not necessarily provided. However, it is preferable to provide the elastic member 14 in terms of enhancing the retention of the core material 3 and absorbing external shocks to protect the core material 3. Here, examples of the rubber include natural rubber, acrylic rubber, nitrile rubber, isoprene rubber, urethane rubber, ethylene propylene rubber, chlorosulfonated polyethylene, epichlorohydrin rubber, chloroprene rubber, silicone rubber, styrene / butadiene rubber, Synthetic rubbers such as butadiene rubber, fluorine rubber, and polyisobutylene are listed.

  Moreover, in the said embodiment, in order to fix the attitude | position of the said clamp part 5b, the lock lever 12 attached to the engagement pin 5g by the side of the main-body part 5a is used inside the clamp part 5b. A lock mechanism may be used. However, it is preferable to use the fixing / releasing mechanism using the lock lever 12 because it is easy to operate and requires less installation space.

  And in the said embodiment, although the mounting base (B) 4 on the short side frame 1b of the base 1 is not made to fall down in particular, you may make it provide so that it can fall down. In this case, the storage space when the roll support base is not used can be further reduced.

  Moreover, in the said embodiment, although the standing part 4a of the mounting base (B) 4 is not made especially extendable, you may make it provide so that extension is possible. In this case, there is an advantage that the height of the mounting table (B) 4 can be finely adjusted according to the amount of the remaining film wound around the core material 3.

  Further, in the above embodiment, the mounting positions of the mounting table (A) 2 and the mounting table (B) 4 are not particularly changeable. For example, as shown in FIG. it can. In this case, a plurality of mounting holes for mounting the mounting table (A) 2 are provided in the longitudinal direction of the inner frame 1c of the base 1, and another base is provided between the two inner frames 1c. When a guide frame extending in the center of 1 is provided and a plurality of mounting holes for mounting the mounting table (B) 4 are provided in the longitudinal direction of the guide frame, a plurality of roll bodies 6 having different widths are prepared. The mounting position of the mounting table (A) 2 and mounting table (B) 4 can be freely changed according to the width of the roll body 6. Therefore, it is not necessary to prepare and store roll support bases as many as the size (width) of the roll body 6, and cost reduction and space saving can be achieved. In FIG. 4, the mounting table (A) 2 and the mounting table (B) 4 are arranged so that each roll body 6 is brought close to the central portion of the base 1, but these are placed on one side of the base 1. You may make it approach. From the viewpoint of stacking the roll support in a well-balanced manner, it is preferable to approach the central portion, but considering work efficiency, it is preferable to approach one side.

  The roll support base of the present invention supports a roll body formed by winding a sheet-like long article such as a plastic film around a core material at both right and left ends of the core material, and is stored or transported in a state where the roll body is horizontally mounted. Available to do.
