[Problems to be solved by the invention]
However, the conventional roll pallet configured as described above has a problem that it is difficult to safely and reliably transport (including transport by forklift, transport by vehicle, etc.) and hold the roll.
That is, when the film-like material is wound around the mandrel 32 to form the roll 33, the end of the mandrel 32 to be grasped by the grasping portion 24 because the width of the film-like material is large or the winding position is shifted. The exposed part of the part (hereinafter simply referred to as the exposed part as appropriate) is reduced, and the roll 33 is detached from the gripping part 24 due to vibration during transportation, etc., or the exposed part to be gripped by the gripping part 24 is eliminated, and the pallet is used. Sometimes things could not be done.
[0017]
Further, in the prior art, the gantry 2 is not particularly locked in the vertical direction. This is because even if vibration or force in the vertical direction is applied during transportation or the like, since the roll 33 itself is heavy, even if the gantry 2 is detachably installed on the pallet body 1, This is because it has been considered that the mount 2 does not jump off due to the weight of the added roll 33. However, in reality, the gantry 2 may jump off due to vibrations or the like generated when the roll 33 is transported by the pallet, and the roll 33 may be damaged, or the convex portion 26 may be detached from the gantry locking groove 27. there were.
[0018]
Furthermore, when an axial force is applied to the pallet due to rolling or the like when transporting with a forklift, a large force is applied to a portion where the base 16 and the pallet main body 1 are in contact, and the base 16 may be damaged.
Of course, if the base 16 is increased in thickness and size, it can be prevented from being damaged, but this is not preferable because it increases the weight and size. In particular, it is desirable to make the size of the base 16 in the axial direction as small as possible.
[0019]
The present invention was devised in view of the above-described problems, and relates to a roll loading pallet for loading a roll formed by winding a film-like object such as a plastic film or paper around a core shaft.

[0041]
By the way, if the sum of the axial distances of both the left and right gripping portions 24 in FIG. 1 is the required gripping length L1, the core shaft 32 of the roll 33 is an exposed portion where the film-like material at the end of the core shaft 32 is not wound. When the axial length (exposed portion length) L is equal to or greater than the required gripping length L1, that is, when the mandrel 32 can be gripped by the gripping portion 24 and the gripping portion 37 as a whole, as shown by a two-dot chain line in FIG. In addition, the mandrel 32 can be directly gripped by the grip portions 24 and 37. However, when the exposed portion length L does not reach the required gripping length L1, the exposed portion of the mandrel 32 cannot be grasped by the entire grasping portions 24 and 37, so that the mandrel 32 is disengaged from the grasping portion 24 and the roll 33 is There is a risk of falling. In order to prevent this, in this embodiment, as shown in FIG. 6, a roll stacking structure is adopted in which the plated adapter 45 is connected to the core shaft 32 and is gripped by the gripping portions 24 and 37.
[0042]
The roll stacking structure will be described. The core shaft 32 is formed in a hollow shaft shape, and adapters 45 are installed at both ends thereof. As shown in FIG. 7, the adapter 45 is formed in a hollow shaft shape, the fitting portion 46 that is one end of the adapter 45 is formed smaller than the inner diameter of the core shaft 32, and the fixing portion 47 that is the other end is a center. The shaft 32 is formed to have the same diameter as the outer diameter of the shaft 32.
[0043]
Each of the fitting portion 46 and the fixing portion 47 is formed to have an axial length sufficient to support the roll 33. Further, an overhang portion 48 larger than the outer shape of the core shaft 32 is formed in the center portion in the axial direction of the adapter 45. Therefore, when the fitting portion 46 is fitted into the end portion of the core shaft 32, the fixing portion 47 and the overhang portion 48 protrude from both ends of the core shaft 32.
[0044]
In addition, a portion (hereinafter referred to as “alame”) 49 having a surface rougher than the outer peripheral surface of the mandrel 32 is formed on the outer periphery of the fixed portion 47 to prevent slippage.
An adapter lid 51 serving as an adapter engaging member having a bolt hole 50 penetrating through the center is provided at the end of the fixing portion 47. A lid locking portion 52 that locks the adapter lid 51 to the adapter 45 is formed on the outer periphery of the adapter lid 51. Further, a long bolt 53 that connects the adapter cover 51 of the adapter 45 fitted at both ends of the core shaft 32 passes through the bolt hole 50 of the adapter cover 51, and the long bolt 53 is a nut 54. The adapter lid 51, the long bolt 53, and the nut 54 constitute the adapter connecting member 55. Therefore, both adapters 45 inserted into both ends of the core shaft 32 are connected by the adapter connecting member 55, and the adapter 45 inserted into both ends of the core shaft 32 is a long bolt that penetrates the inside of the core shaft 32 and the adapter 45. It is clamped by the adapter lid 51 connected at 53. Here, a special bolt in which the nut 54 is screwed to both ends of the long bolt 53 has been described as an example, but a general bolt may be used as a matter of course. In this case, one end of the bolt is locked to one adapter lid 51 by the bolt head.
[0045]
Since the roll loading pallet and the roll loading structure as one embodiment of the present invention are configured as described above, when the rolls 33 are loaded, the distance between the gantry 2 is set at the both ends of the core shaft 32. By selecting the gantry fixing hole 9 so as to be longer than the axial distance by the required gripping length L1, one roll pallet can be used for rolls of various axial lengths.
[0046]
Further, by inserting the gantry fixing pin 21 into the gantry fixing hole 9 and fixing the gantry 2 to the pallet main body 1, the gantry 2 is displaced horizontally with respect to the pallet main body 1 when vibration occurs. Can be prevented.
Further, by holding the mandrel 32 from above and below by the grasping portions 24 and 37, the mandrel 32 can be reliably held on the pallet. That is, the mandrel fixing plate 34 of the gantry 2 is raised and the exposed portion of the mandrel 32 is loaded on the grip portion 24 of the gantry 2, and then the mandrel fixing plate 34 is lowered and the mandrel fixing plate 38 is fixed with the fixing screw 38. By fixing 34 to the gantry 2, the exposed portion of the mandrel 32 is grasped by being sandwiched between the grasping portion 24 and the grasping portion 37 with rubber lining, so that the mandrel 32 is displaced in the axial direction. Is prevented.
[0047]
Moreover, since the side surface of the roll 33 is clamped inside in the axial direction by the protective plate 3, it is possible to prevent the roll from slipping out into a bamboo shoot shape. That is, the handle 31 is turned to cause the protective plate 3 installed on the two gantry 2 to project together and pressed against the side surface of the roll 33, so that the roll 33 is sandwiched between the protective plates 3 and the roll 33 vibrates due to vibration. Therefore, it is possible to prevent deformation.
[0048]
Further, since the jump prevention pin 40 is fitted in the jump prevention hole 41, the mount 2 is locked in the vertical direction, and the mount 2 jumps even if vibration occurs in the vertical direction during transportation. This can prevent the roll 33 from jumping. That is, since the roll 33 is pressed and held together with the mandrel 32 by the gripping portion 37, the roll 33 is not detached from the gantry 2, and the gantry 2 is fixed to the base 16 by the jump prevention pins 40. Therefore, it does not leave the base 16. Since the base 16 is fixed to the pallet main body 1 by the mounting frame 20, the roll 33 is fixed to the pallet main body 1, and the roll 33 can be prevented from jumping.
[0049]
Even if horizontal vibration occurs during transportation, the reinforcing members 42 and 43 are installed, so that the strength and rigidity of the base 16 can be increased and the base 16 can be prevented from being damaged.
Moreover, the pallet of this embodiment can fold the support | pillar 8 when not using it, Therefore The space required in order to transport pallet itself can be saved.
[0050]
On the other hand, when the mandrel 32 having the exposed portion length L of the mandrel of less than the required grip length L1 is loaded on the pallet, the adapter 45 is used. That is, the adapter 45 is fitted into both ends of the core shaft 32, and the adapter cover 51 is connected with the long bolt 53 that penetrates the inside of the core shaft 32 and the adapter 45, so that the adapter 45 is fixed to the core shaft 32. To do. As a result, even a roll having no or no exposed portion of the mandrel can be loaded on the pallet.
[0051]
By the way, since the mandrel 32 and the adapter 45 are usually formed of metal, if the mandrel 32 and the adapter 45 are rubbed by vibration or the adapter 45 is damaged and rust is generated from there, the metal from the vicinity of the adapter 45 There is a risk of powder generation. Since the adapter 45 is near the roll 33, when metal powder is generated, the metal powder adheres to the roll 33, which causes the quality of the roll 33 to deteriorate. However, in the present embodiment, since the adapter 45 is plated, it is possible to prevent the metal powder from being generated by rubbing or scratching the adapter 45 and generating rust.
[0052]
In addition, since the armature 49 is formed on the outer periphery of the fixed portion 47, the adapter 45 can be prevented from being displaced in the horizontal direction by the grip portions 24 and 37.
Further, since both adapters 45 are connected by the adapter connecting member 55 and the adapter 45 sandwiches the mandrel 32, the adapter 45 is securely fixed to the mandrel 32 without the adapter 45 being detached from the mandrel 32. be able to. Moreover, since the adapter 45 can be fixed with respect to the core shaft 32, there is no possibility that the shaft 32 and the adapter 45 are rubbed as described above, and the generation of metal powder can be prevented.
[0053]
  Further, at this time, since the lid locking portion 52 is formed on the adapter lid 51, the adapter lid 51 does not shift in the radial direction of the adapter 45.
  Long bolt 53By screwing nuts 54 to both ends of the bolt, the long bolt 53Is prevented from protruding only in one axial direction, and the long bolt 53Can be protruded from the adapter lid 51 in a balanced manner.
[0054]
In this way, by using the adapter 45 as appropriate, it is possible to appropriately load various types of rolls 33 with a small number of types of roll loading pallets, and further, the movable range of the protection plate 3 can be reduced. Even if set, it can correspond to various roles.
In the above configuration, the base 16 has been described as a separate component from the gantry 2, but even if the base 16 and the gantry 2 are combined and recognized as a gantry according to the pallet and roll stacking structure of the present invention, It is not out of the gist. In that case, in addition to the jump prevention pin 40 and the jump prevention hole 41, it should be seen that the vertical locking structure including the locking portion 20 is configured.
[0055]
Although the embodiments of the present invention have been described above, the present invention is not limited to such embodiments, and various modifications can be made without departing from the spirit of the present invention.
For example, several pairs of mounts may be installed on one pallet so that a plurality of rolls can be loaded on one pallet. Thereby, many rolls can be hold | maintained or conveyed efficiently.
[0056]
Further, the reinforcing member may not be a block shape having a square cross section, and may be installed by a method other than welding, and can be reinforced by an appropriate method.
Further, a part of the protruding portion of the adapter may be brought into contact with the side surface of the roll to prevent the roll from being deformed into a bamboo shoot. Thereby, the structure of a mount frame can be simplified.
[0057]
Further, an adapter may be used when there are sufficient exposed portions of the mandrel around which no film-like material is wound. Thereby, rolls of various axial lengths can be held or transported without adjusting the position of the gantry.
Further, if the gantry and the base are integrally configured so that the gantry is not folded, the strength of the gantry can be further increased.
[0058]
Further, the mandrel fixing plate 34 may be fixed to the roll support beam 23 by welding the support portion 35, the screw hole 36, and the fixing screw 38 to the roll support beam 23. According to this, the strength of the gantry can be increased, and the mandrel and the adapter can be securely fixed by the grip portion.
[0059]
