Description

[Technical field]

[0001] The present invention relates to a device for easily removing a roll of canvas blank when making canvas to be used as a duct joint, and in particular to a device that temporarily stores a blank roll and can pull out the blank from the edge side while rotating the blank roll. [Background technology]

[0002] Ducts used in air conditioning equipment, smoke exhaust equipment, etc. use joints (canvas joints) made of a non-flammable, fire-resistant fabric called canvas to absorb vibrations generated by the operation of the drive parts (air blower drive parts, etc.) that make up the equipment. Canvas joints are made of canvas formed into a tubular shape (cylindrical or rectangular tube) with flange parts attached to both ends, and the flange parts are used to connect ducts together or to a blower, etc. Joints that use canvas are generally called "canvas joints," but recently, joints formed into a tubular shape are simply called "canvas" regardless of whether they have a flange part. Here, we will not strictly distinguish between those with and without a flange part, but will call those formed into a tubular shape canvas and the material used for the canvas a blank.

[0003] Generally, when making canvas, a canvas blank is cut to a specified area and processed into a cylindrical shape by appropriately curving or folding, and the blank is manufactured in a continuous, long state. This continuous, long blank is usually in a roll, and since the roll width corresponds to the length of the joint, several types of blanks with different roll widths are sold wound up to the same roll diameter. Canvas processors use the blanks one by one, starting from the outermost one, while rotating (unrolling) the rolled blank roll. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Publication number 05-26427 [Patent Document 2] JP 2018-66508 A Summary of the Invention [Problem to be solved by the invention]

[0005] Regarding canvas blanks, there are ones in which flanges are formed to connect to both sides of the canvas (see Patent Document 1), and regarding canvas, there are ones in which the blanks for canvas are folded in a wavy shape (see Patent Document 2). The aforementioned Patent Documents 1 and 2 each disclose methods for manufacturing canvas.

[0006] However, these prior art techniques were developed for processing a long blank after it has been cut to an appropriate length, and did not address the operational efficiency of using only the appropriate length of a blank roll containing a long blank in a rolled state. Therefore, those who actually process the blank select a blank roll with the required roll width, rotate (unwind) the roll little by little, take out the required length, and cut it for use.

[0007] Recently, prefabricated blanks have been developed, and these blanks are made of a main cloth made of glass fiber or other inorganic fibers, and edging materials such as galvanized steel sheets or galvalume steel sheets (registered trademark) for flanges are pre-connected to both sides of the main cloth. The entire blank roll has an outer diameter of about 580 mm, a width of at most 300 mm, and a roll thickness of about 50 mm, so the total weight is about 20 kg or more. This weight is not extremely heavy, but it is by no means light. In addition, the roll width varies depending on the length of the joint to be processed, so there are multiple types. Therefore, a blank must be selected appropriately for each canvas production, and the work of moving and removing the blank is troublesome and not easy.

[0008] The present invention has been made in consideration of the above-mentioned points, and its object is to provide an apparatus that can temporarily store a raw sheet roll and easily remove only the required length. [Means for solving the problem]

[0009] Therefore, the present invention is a canvas blank removal device for temporarily storing a blank roll in which a canvas blank is wound into a roll and pulling out a predetermined length of blank while rotating the blank roll, and is characterized in that it comprises a storage section large enough to store the blank roll with the axis of the blank roll oriented horizontally, a plurality of abutment-type support sections provided in the storage section which abut against the surface of the blank roll and support the axis of the blank roll oriented horizontally, a pull-out opening at the lower front side of the storage section which allows the blank to be continuously pulled out from the edge of the blank roll to the outside of the storage section, and a regulating roller suspended parallel to the axial direction of the blank roll at an appropriate position of the pull-out opening and regulating the pulling direction of the continuous blank being pulled out.

[0010] According to the above configuration, the blank roll is stored in the storage section with its axis oriented horizontally, and the blanks can be successively removed by pulling out the ends of the blank roll from below. When the blanks are pulled out, the blanks wound around the blank roll will still have a curling tendency (a slightly curved, deformed state) that occurs when they are wound, but because the extension direction is forced by the regulating rollers, the blanks are pulled out warped in the opposite direction, eliminating the curling tendency. In addition, by pulling out the ends of the blank roll from below at this time, a reaction force due to the weight of the blank roll acts, making it possible to suppress movement (movement) of the storage position of the blank roll.

[0011] In the invention having the above configuration, the multiple abutment-type support portions can all be constituted by long rollers suspended in the axial direction of the base plate roll, and can be configured as roller-type support shafts that are distributed at least above, below, and to the sides of the base plate roll.

[0012] In the above configuration, when the blank roll is stored in a predetermined position, it can be supported by line contact at multiple positions by the multiple roller-type support shafts, and the blank can be stored in a gradually lowered state depending on the use state (pulled-out state) of the blank, stabilizing the position of the end portion at the bottom of the blank roll. Also, since the roller-type support shaft is composed of a long roller, when the blank roll rotates, the rotation of the roller-type support shaft ensures a smooth rotation state, and resistance when the blank is pulled out can be reduced.

[0013] In addition, in the invention having the above configuration, the bottom of the storage section can be configured to be provided with a bottom-side support shaft, in which at least two roller-type support shafts abut against the surface of the raw material roll when the raw material roll is stored therein.

[0014] In the case of the above configuration, for example, by arranging the support shafts on both sides of the lowest part of the surface of the blank roll using two bottom side support shafts, the lowest part of the surface of the blank roll can be stably supported. Furthermore, since both sides of the lowest part are slightly higher than the lowest part, it is possible to suppress lateral movement (along with the roll) when the roll is pulled out.

[0015] Furthermore, in the invention of the above configuration, an insertion opening is provided on the front side of the storage section above the withdrawal opening for inserting the blank roll into the storage section, and among the multiple roller-type support shafts, the front side support shaft that abuts against the blank roll on the front side of the storage section and the upper side support shaft that abuts against the blank roll on the upper side of the storage section can be configured so that their installation positions in the height direction can be changed.

[0016] In the above-mentioned configuration, since the insertion opening is provided above the withdrawal opening, the blank roll can be inserted from above and placed on the bottom support shaft in the storage section. The front support shaft supports the lateral front side of the blank roll, and the upper support shaft supports the upper part of the blank roll, and by making these positions movable, a sufficient gap between them can be secured when inserting the blank roll.

[0017] Furthermore, in the invention having the above configuration, the front side support shaft is maintained in a lowered state when the raw plate roll is inserted, and in the lowered state, the front side support shaft guides the raw plate roll to abut against the bottom side support shaft at a position higher than the regulating roller and higher than the bottom side support shaft abutting the bottom side of the raw plate roll, and the upper side support shaft is maintained in a raised state when the raw plate roll is inserted, and in the raised state, the upper side support shaft can be configured so that it can be sufficiently separated from the surface of the raw plate roll when the raw plate roll abuts against the lowered front side support shaft.

[0018] In the above configuration, by lowering the front support shaft and raising the upper support shaft, a sufficient gap can be secured between them, making it easy to insert the blank roll. Furthermore, since the front support shaft is located higher than the regulating roller when lowered, the regulating roller is prevented from becoming an obstacle when inserting the blank roll. On the other hand, the front support shaft in the lowered state is located higher than the bottom support shaft that abuts on the bottom side of the blank roll, and the blank roll to be inserted abuts on the front support shaft before abutting on the bottom support shaft, so that a suitable inclination is formed between the front support shaft and the bottom support shaft, which can guide the moving direction of the blank roll.

[0019] Furthermore, in the above configuration, the upper support shaft can be provided with a biasing means for biasing the upper support shaft downward, and can be configured to be able to bias the blank roll from above when in contact with the blank roll, and can be made to be able to rise against the biasing force of the biasing means.

[0020] In the above configuration, the upper support shaft can apply a downward urging force from above the blank roll, thereby preventing the blank roll from floating up when it is rotated. Furthermore, the contact by the upper support shaft is lowered by the urging force even when the blank roll is consumed and its outer diameter is reduced, so that the contact state can be maintained regardless of the condition of the blank roll. Note that the urging means may be a spring or other elastic member, or the weight of the upper support shaft may be increased to apply the urging force.

[0021] In the invention of each of the above configurations, of the wall surfaces constituting the storage section, the front portion arranged on the front side may be formed by bending each edge portion of a rectangular plate material into a shallow tube with a bottom that opens toward the inside of the storage section, and the configuration may be such that the tip of the wire can be temporarily held inside this shallow tube with a bottom.

[0022] In the case of the above-mentioned configuration, when the blank is not being drawn out (such as after work is finished), the leading edge of the remaining part of the blank drawn out from the blank roll is inserted into the shallow cylindrical part with a bottom at the front part, thereby preventing the leading edge from protruding from the storage part. Since the leading edge of the blank does not protrude from the storage part in this way, it is possible to prevent workers from inadvertently touching the leading edge and thus preventing injury to workers.

[0023] In the invention having each of the above configurations, a plate-like protective member having an appropriate area and projecting in the extending direction of the wire may be provided on both sides of the extraction opening.

[0024] In the above configuration, since there are plate-like members protruding from at least both sides of the opening, after the blank is pulled out and cut to the length to be used, the cut edges are protected from the sides of the storage section. This protection is provided to prevent workers from coming into contact with the cut edges when moving to a position close to the storage section, and protects the end faces of the blank while at the same time preventing workers from being injured by contact. Effect of the Invention

[0025] According to the present invention, it is possible to store a blank roll with its axis oriented horizontally in the storage section, and since the blank can be used by pulling out the end at the bottom of the blank roll, it can be easily removed by pulling out the length corresponding to the length to be used. Furthermore, in the present invention, a regulating roller is provided near the removal opening, and by regulating the pulling direction of the blank, the blank being pulled out is forced in the regulated direction, so that the blank pulled out from the position extending from the blank roll abuts against the regulating roller and the pulling direction can be changed, and the curling tendency of the blank (a slightly curved residual deformation state) can be eliminated at the same time as the blank is pulled out.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. <Overview of the embodiment> First, an outline of this embodiment will be described. FIG. 1 is a diagram showing an outline of this embodiment. As shown in this figure, the canvas blank take-out device 1 of this embodiment is configured to include a box-shaped storage section 10 having a capacity large enough to store a blank roll A formed by winding a canvas blank in a roll shape, and a plurality of abutment-type support sections 20 suspended inside the storage section 10. The storage section 10 has side sections 12, 13 standing on both sides of a bottom section 11, a top plate section 14 at the upper end of the side sections 12, 13, a front section 15 and a back section (not shown) at the front and back, and by opening the front section 15 and the top plate section 14, a pull-out opening 30 is provided at the lower front side, and an insertion opening 40 is provided at the upper front side.

[0028] The contact-type supports 20 are arranged on the bottom of the storage section 10, as well as on the front, back and top sides, and are capable of contacting the blank roll A from the periphery, so as to maintain the axis of the blank roll A horizontally. Some of the contact-type supports 20 are suspended with both ends inserted into guide grooves 2, 3 that are groove-shaped and penetrate the side sections 12, 13, and are movable along the guide grooves 2, 3. Some of the contact-type supports 20 are equipped with biasing means 4 that bias the supports in a predetermined direction along the inside of the guide groove 3. The other contact-type supports 20 that are not suspended by the guide grooves 2, 3 are suspended with their tips inserted into insertion holes 21 provided in the side sections 12, 13.

[0029] The top panel 14 is provided with an operation window 5 that is used when moving a part of the abutment type support part 20, which will be described later, and the side panels 12, 13 are provided with remaining amount confirmation windows 6 at appropriate positions for checking the remaining amount of the blank roll A. Casters 7 are also provided at four places on the underside of the bottom panel 11. Since it is expected that the canvas blank removal device 1 will weigh well over 10 kg, the casters 7 allow easy movement when moving the device. In particular, when the blank roll A is stored, it will weigh over 30 kg, so the casters 7 can be used to assist in making the device easier to move.

[0030] <Detailed configuration of each part> Next, each component will be described in detail. Figure 2 is a cross-sectional view taken along line II-II in Figure 1. Therefore, except for one side surface 12 of the storage unit 10, the state of the bottom surface 11, the remaining side surface 13, the top plate 14, the front surface 15, and the back surface 16 can be confirmed, and the internal structure of the box-shaped storage unit 10 is shown in Figure 2.

[0031] 2, in this embodiment, the multiple contact-type support parts 20 are composed of multiple long rollers, each of which is composed of roller-type support shafts 201-206. The roller-type support shafts 201-206 have a fixed central shaft and a circumferential portion that is freely rotatable. Therefore, when the blank roll A rotates, the roller-type support shafts 201-206 with which the surface of the blank roll A comes into contact can easily change the contact position while rotating.

[0032] Here, the bottom support shafts 201 and 202 are arranged adjacent to the bottom surface 11 of the storage section 10, the front support shaft 203 is provided in a position adjacent to the front surface 15, and the top support shaft 204 is provided in a position adjacent to the top plate section 14. Side support shafts 205 and 206 are also provided in a position adjacent to the back surface section 16 to support the sides of the raw plate roll A. In this way, by distributing the roller-type support shafts 201-206 above, below, and to the sides of the position where the raw plate roll A should be stored, the raw plate roll A is supported in contact with the periphery and the storage state is maintained stably.

[0033] A regulating roller 50 is provided near the drawing opening 30 provided on the front side of the storage section 10. This regulating roller 50 is basically composed of a long roller having the same structure as the roller-type support shaft, but is provided for a different purpose from the other roller-type support shafts in that it is not brought into contact with the stored blank roll A.

[0034] That is, the regulating roller 50 is provided inside the drawing opening 30 and suspended at a position slightly higher than the positions of the bottom support shafts 201, 202. The regulating roller 50 comes into contact with one side of the blank B drawn out from the blank roll A. Therefore, the drawn blank B extends outward from the opening 30 while being in sliding contact with the lower part of the regulating roller 50.

[0035] In this way, by restricting the drawing direction of the blank B, it is possible to eliminate the curling tendency (slightly curved deformation) remaining in the blank B wound in a roll shape. That is, in this embodiment, the bottom side of the blank roll A is supported by two bottom side support shafts 201, 202 distributed at two positions appropriately separated from the center, so that both bottom side support shafts 201, 201 are in contact with the surface of the blank roll A slightly above the lowest position of the blank roll A. The position from which the blank B is drawn is a position beyond the bottom side support shaft 201 on the drawing side (the side closer to the drawing opening 30) of the two bottom side support shafts 201, 201, so that the blank B goes over the bottom side support shaft 201 and separates from the blank roll A. At this time, the curling tendency remaining in the blank B has the peripheral shape (arc-shaped) of the blank roll A, so the blank B is in a state of being greatly inclined and facing obliquely upward. By pulling the blank B, which has been released from the blank roll A, greatly downward in this obliquely upward direction and making it pass under the regulating roller 50, it is possible to apply a deformation load in the opposite direction to the deformation direction remaining as the curling tendency.

[0036] The front support shaft 203 and the upper support shaft 204 are configured so that the positions to be installed can be changed. Specifically, the heights are changed along the guide grooves 2 and 3, and the changed state is maintained. The guide grooves 2 and 3 are both provided in a substantially J-shape, and are stably supported at the positions of both ends 2a, 2b, 3a, and 3b. The center portions (fixed shafts of the rollers) of the front support shaft 203 and the upper support shaft 204 are inserted into the guide grooves 2 and 3, and the fixed shafts are movable along the guide grooves 2 and 3. Therefore, the peripheral portions (rotating portions of the rollers) can change according to the position of the fixed shafts.

[0037] The guide groove 2 that restricts the movement of the front support shaft 203 has one end 2a at a different height from the other end 2b, and when the front support shaft 203 is moved to the upper end 2a position, it is brought into contact with the surface of the blank roll A, and when the front support shaft 203 is moved to the lower end 2b position, it is for inserting the blank roll A. The front support shaft 203 is stabilized at either one of the ends 2a, 2b, and can be raised and lowered.

[0038] The guide groove 3, which restricts the movement of the upper support shaft 204, can abut against the surface of the blank roll A when it is located at the lower end 3a, and can allow the blank roll A to be inserted without any problems when it is located at the upper end 3b. However, the upper support shaft 204 is provided with the above-mentioned biasing means 4 (tension spring, see FIG. 1) and is biased toward the lower end 3a. Therefore, the position of the upper support shaft 204 is not stable at the lower end 3a, but is stabilized at a suitable lowest point by the biasing force of the biasing means 4. The movement to the upper end 3b is caused by the forced upward movement against the biasing force of the biasing means 4. If the biasing force of the biasing means 4 is not strong, the movement to the other end 3b is easy.

[0039] The position of the front support shaft 203 is moved solely through the insertion opening 40, while the position of the upper support shaft 204 is moved through the operation window 5. These movements are performed manually by an operator, and each support shaft 203, 204 can be moved appropriately by lifting it up by hand. Each support shaft 203, 204 is relatively light and the blank roll A contained in the storage section 10 is not driven to rotate, so that it can be moved sufficiently by manual operation, but the shafts may also be movable outside the storage section 10 (outside the side sections 12, 13).

[0040] Therefore, as shown in Figure 3, by positioning the front side support shaft 203 at a lower position (moving it to the other end 2b of the guide groove 2) and positioning the upper side support shaft 204 at a higher position (moving it to the other end 3b of the guide groove 3), both support shafts 203, 204 are far away from the vicinity of the insertion opening 40, making it easier to insert the blank roll A through the insertion opening 40.

[0041] As shown in FIG. 3, the front support shaft 203 is located above the regulating roller 50 when it is disposed at the lower position, and therefore has the function of preventing the raw plate roll A to be inserted from contacting the regulating roller 50. The front support shaft 203 is located above the bottom support shafts 201 and 202, and the distance between the front support shaft 203 and the bottom support shaft 201 is narrower than the outer diameter of the raw plate roll A. Therefore, the raw plate roll A to be inserted can be moved so that it is hung from the front support shaft 203 to the bottom support shaft 201 (front side) and then hung on the other bottom support shaft 202, and has the function of guiding the insertion direction when the raw plate roll A is inserted. After being hung in this way, the raw plate roll A is gradually guided diagonally downward, and is finally stably supported by the two bottom support shafts 201 and 201 in contact with the bottom surface of the raw plate roll A (see FIG. 2).

[0042] In the state where the raw plate roll A is supported by the two bottom support shafts 201, 202 as described above (see FIG. 2), the side support shafts 205, 206 come into contact with the surface of the raw plate roll A on the back side, stabilizing the installation state after insertion. Furthermore, the front support shaft 203 and the top support shaft 204 return to their original positions (to the ends 2a, 3a), so that the front and top surfaces of the raw plate roll A are also abutted by these support shafts 203, 204, resulting in an even more stable installation state.

[0043] <Usage> Next, a usage mode of this embodiment will be described. Figures 4 and 5 are diagrams showing a usage mode of this embodiment. It is assumed that the raw material roll A has already been accommodated in the accommodation section 10 as described above.

[0044] As shown in FIG. 4(a), in the state in which the raw plate B is accommodated in the accommodation section 10, it is prepared in a state in which it is separated from the raw plate roll A at the bottom of the raw plate roll A. Since the raw plate roll A is wound in a roll shape, it can be taken out one by one from the surface. The direction of taking out the raw plate B to be taken out is prepared in advance so that it passes above the bottom side support shafts 201, 202 (particularly the bottom side support shaft 201 on the front side) as shown in the figure. By drawing out the raw plate B in this state, the raw plate roll A rotates clockwise in the figure. Note that the tip (edge) Ba of the raw plate B to be taken out is lifted upward due to its tendency to roll up, and is therefore located above the drawing opening 30, but in order to prevent the tip (edge) B from protruding outward, it can be positioned inside the bottomed shallow tube part of the front part 15. In the initial stage when the base plate roll A is inserted, it is possible to adjust the protruding length of the base plate B so that it does not reach the shallow cylindrical portion of the front portion 15 (does not protrude outward either), but after use, a base plate B of an appropriate length is separated from the base plate roll A, and the end portion (edge) Ba is positioned as shown in the figure.

[0045] From the above state, the blank B is pushed down to move it below the regulating roller 50. This state is shown in FIG. 4(b). To push down the blank B, a rod-shaped member of an appropriate length is inserted through the insertion opening 40 and the upper surface of the blank B is pushed down, causing the blank B to be temporarily curved and deformed, and it can be moved below the regulating roller 50. After use, an L-shaped member can be inserted through the insertion opening 40 and lifted up by hooking the side edge, thereby moving the blank B above the regulating roller 50. The rod-shaped member for moving the blank B is not particularly limited, so it is sufficient to use one of appropriate length and shape.

[0046] As shown in Fig. 4(b), the raw plate B is ready for use when it is positioned below the regulating roller 50. The raw plate B is manually drawn out by an operator who holds a part of the raw plate B and pulls it out through the removal opening 30. At this time, the raw plate roll A is supported by a plurality of roller-type support shafts 201-206, and rotates clockwise in the figure as the raw plate B is drawn out.

[0047] The blank B drawn out of the storage section 10 (through the drawing opening 30) is cut according to the required length and used, but the remaining part is in a state similar to that shown in FIG. 4(b). If it is to be used further, it can be further used by drawing out the blank B by holding the tip of the blank B. If a blank B longer than necessary is drawn out, the excessively drawn part can be pushed in the backward direction artificially. In the pushing operation, the blank B can be easily pushed back into the storage section 10 by pushing it through the drawing opening 30 toward the inside of the storage section 10. At this time, the blank roll A may need to be turned over, but since it is in a state where it can be rotated relatively easily, there is no particular factor that prevents it from being pulled back. In this way, the blank B can be repeatedly drawn out from the drawing opening 30, and the drawing operation can be performed many times by the same operation.

[0048] Since the raw plate roll A is wound in a roll shape, the number of turns of the raw plate roll A gradually decreases as the raw plate B is repeatedly pulled out. The decrease in the number of turns of the raw plate roll A changes the outer diameter of the raw plate roll A. In such a case, as shown in FIG. 5(a), if the outer diameter is simply reduced, at least the front support shaft 203 and the side support shafts 205 and 206 provided on the back side may be unable to abut against the surface of the raw plate roll A, but the abutment with the bottom support shafts 201 and 202 is maintained, so the posture of the raw plate roll A is not significantly affected. In addition, the upper support shaft 204 is biased downward by the biasing means 4 (see FIG. 1), so that the raw plate roll A can be pressed from above and below.

[0049] Furthermore, as shown in Fig. 5(b), when the number of turns of the raw plate roll A is reduced, the wound state may become loose and the raw plate may expand (due to the restoring force of the raw plate). In such a case, the bottom support shafts 201, 202 and the top support shaft 204, as well as the front support shaft 203 and the side support shafts 205, 206, come into contact with the surface, and the above-mentioned expansion can be contained in a state of contact with each of the support shafts 201-206. Note that the top support shaft 204 at this time may rise against the biasing force of the biasing means 4 (Fig. 1).

[0050] In either of the above states, the position at which the raw plate B is pulled out from the raw plate roll A (the position at which it separates from the raw plate roll A) is directly above one of the bottom support shafts 201 and below the regulating roller 50, which is no different from the state when there are a large number of turns.

[0051] <Summary> Since the embodiment of the present invention is as described above, the raw plate roll A is maintained in a state where it is temporarily stored inside the storage section 10 with its axis oriented horizontally, and the raw plate B to be used of the desired length can be easily taken out by pulling out the raw plate B which is separated at the bottom from the surface of the raw plate roll A. At this time, the support state of the raw plate roll A is maintained by the multiple support shafts 201-206 abutting against the surface, making it easy for the raw plate roll A to rotate, and making it possible to pull out the raw plate B without requiring a strong force.

[0052] In addition, since a regulating roller 50 is provided near the drawing opening 30, the drawing direction of the raw plate B being drawn out is regulated, and by simply drawing out the raw plate B at the abutment position of the bottom side support shaft 201 at the position where it is separated from the raw plate roll A and the abutment position of the regulating roller 50, any curling tendency remaining in the raw plate B can be simultaneously eliminated.

[0053] <Modification> The above-described embodiment is merely an example of the present invention, and the present invention is not limited to the above-described embodiment. Therefore, each element of the above-described embodiment may be changed, or other elements may be added.

[0054] For example, as shown in FIG. 6(a), a configuration can be adopted in which protective members 8 are provided on both sides of the drawer opening 30 provided at the lower front side of the storage section 10. The protective members 8 are formed of plate-shaped members protruding from the edges of the drawer opening 30 in the drawing direction on both the left and right sides. As shown in the figure, the protective members 8 are protruding to a length equivalent to the range in which the blank B slightly protrudes from the drawer opening 30, so that the leading edge Ba of the blank B is protected so as to avoid contact with at least the lateral side. Note that the protection here refers to protection for preventing a worker from contacting the leading edge Ba of the blank B when approaching the storage section 10, and means protection for preventing deformation or damage around the leading end of the blank B, as well as protection for preventing injury due to contact by the worker. It is to protect the blank B from contacting the leading edge Ba of the blank B when passing nearby (contacting sideways when passing by). When this type of protective member 8 is in the form of a thin plate, it is desirable that it has an appropriate thickness in case the edge of the protruding piece can also cause injury.

[0055] Further, in the above embodiment, only one regulating roller 50 is used for regulation, but as shown in Fig. 6(b), the pull-out direction of the blank B may be regulated by a plurality of regulating rollers 50 (two in the figure). This is to suppress the load acting on the bottom support shaft 201, and when the curling tendency is eliminated solely by two regulating rollers 50, the load can be concentrated on the regulating roller 50. In this case, it is expected that the rollers will wear out due to the concentration of the load, and in such a case, it will be necessary to replace only the regulating roller 50.

[0056] In the above embodiment, the roller-type support shafts 201-206 are exemplified as the contact-type support part 20, but the structure does not necessarily have to be made of rollers, and it is also possible to use a plate-like support part that can slide and makes surface contact with the surface of the raw plate roll A. However, when the roller-type support shafts 201-206 are used, they are advantageous in that they make line contact with the surface of the raw plate roll A and facilitate the rotation of the raw plate roll A by the rotation of the rollers.
