  An object of the present invention is to provide a conveyor belt transport holder that can stably hold and transport a conveyor belt while preventing deformation of the wound conveyor belt due to its weight and its own weight.

  In order to achieve the above object, a conveyor belt transport holder according to the present invention is a conveyor belt transport holder for holding a wound conveyor belt wound around a winding core. And a connecting member for connecting corresponding ends of both ends of the receiving base and the both ends of the winding core, and the outer periphery of the conveyor belt in the winding state. It has an arcuate mounting portion along the surface, and also has a grounding portion that moves the cradle to a fixed position when the cradle is placed on a flat surface.

  Another conveyor belt transport holder according to the present invention is a conveyor belt transport holder for holding a wound conveyor belt wound around a winding core, on which the wound conveyor belt is placed. A support shaft that penetrates the winding core in the direction of the core axis, a support shaft connecting member that connects corresponding ends of the both ends of the support base and both ends of the support shaft, and the base A connecting member that connects the winding core, and the cradle has an arcuate placement portion along the outer peripheral surface of the wound-up conveyor belt, and the cradle is placed on a flat surface And a grounding portion for moving the cradle to a fixed position.

  In the former conveyor belt transport holder according to the present invention, as described above, since the cradle has the arcuate mounting portion, the conveyor belt is supported by the surface by the arcuate mounting portion, and the conveyor belt is locally Load burden is reduced. Therefore, it is advantageous to prevent deformation of the conveyor belt transport holder. Further, since the arcuate placement portion restricts the movement of the rolled-up conveyor belt in the rolling direction, it can be stably held. Further, when the cradle is placed on a flat surface by the grounding portion, the cradle is fixed to a fixed position, so that the stability of the transporting holder is also ensured. Furthermore, since the movement of the conveyor belt in the axial direction is restricted by the connecting member, the conveyor belt can be stably held.

  Here, the arc length of the placing portion is set to, for example, 20% to 45% of the outer peripheral length of the wound-up conveyor belt. Thereby, since the load burden range of a conveyor belt becomes wide, it becomes easy to prevent a deformation | transformation of the conveyor belt conveyance holder further. Moreover, it becomes easier to regulate the movement of the conveyor belt in the rolling direction.

  A length adjusting unit for adjusting the connecting length of the connecting member can also be provided. Thereby, since it becomes possible to hold | maintain the conveyor belt from which winding outer diameter differs, without replacing | exchanging a connection member, versatility increases.

  A pair of connecting members are provided at each end of the cradle, and the pair of connecting members are connected so that the connecting portion with the winding core is an apex angle, and the apex angle is set to 30 ° to 120 °. It can also be made to the specification that is.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

  1 to 3 illustrate a first embodiment of a conveyor belt transfer holder of the present invention (hereinafter referred to as holder 1). The holder 1 includes a receiving base 10 on which a wound conveyor belt CB is placed on a winding core C, and ends corresponding to both ends of the receiving base 10 and both ends of the winding core C, respectively. And a connecting member 20 that connects the parts.

  The cradle 10 has a placement portion 11 on the upper surface. The mounting portion 11 is formed in an arc shape along the outer peripheral surface of the conveyor belt CB in a wound state. On the other hand, the lower surface of the cradle 10 has a grounding portion 12 that moves the cradle 10 to a fixed position when the cradle 10 is placed on a flat surface. The outer peripheral surface of the conveyor belt CB in the wound state is covered with a resin film such as polypropylene in order to prevent dirt and scratches.

  In the first embodiment, the cradle 10 has a mounting portion 11 composed of a concave curved surface 11a formed by processing an upper surface of a rectangular parallelepiped steel material into an arc shape along the outer peripheral surface of the wound conveyor belt CB. have. The grounding portion 12 is configured by forming the lower surface of the cradle 10 on the flat surface 12a.

  The connecting member 20 is composed of a plate material 21. As a material of the connecting member 20, a metal such as steel or iron, a hard resin, wood, or the like can be employed. In this embodiment, two plate members 21 and 21 are bridged between the cradle 10 and the winding core C, and both ends of the plate member 21 are fixed to the cradle 10 and the winding core C by bolts 22. Yes.

  In the holder 1 of the present invention, since the cradle 10 has the arcuate placement part 11, the conveyor belt CB is supported by the surface by the arcuate placement part 11. Thereby, it is possible to avoid applying an excessive load to a specific part as in the case of conveyance in a state of being wound around a conventional winding drum, and to reduce a local load burden. Therefore, it is advantageous to prevent the holder 1 from being deformed. Further, since the arcuate mounting portion 11 receives the conveyor belt CB in the wound state and restricts its movement in the rolling direction, the conveyor belt CB can be stably held.

  Since the grounding part 12 puts the cradle 10 in a fixed state when the cradle 10 is placed on a flat surface, the stability of the holder 1 is also ensured. Since the movement of the conveyor belt CB that tends to shift in the axial direction during conveyance is restricted by the connecting member 20, it becomes more and more advantageous to stably hold the conveyor belt CB. In addition, since the conveyor belt CB is in surface contact with the mounting portion 11, if the conveyor belt CB moves in the axial direction, the conveyor belt CB is damaged due to friction between the conveyor belt CB and the mounting portion 11. Although there is a possibility, since the axial movement of the conveyor belt CB integrated with the winding core C is restricted by the connecting member 20, this damage can also be avoided.

  For example, the arc length L of the mounting portion 11 is set to 20% to 45% of the outer peripheral length of the wound-up conveyor belt CB. Thereby, since the load burden range of the conveyor belt CB becomes wide, it becomes easier to further prevent the holder 1 from being deformed. Moreover, it becomes easier to regulate the movement of the conveyor belt CB in the rolling direction. If the arc length L of the mounting portion 11 is smaller than 20% of the outer peripheral length of the wound-up conveyor belt CB, the load bearing range of the conveyor belt CB is narrowed, so the effect of preventing the holder 1 from being deformed is reduced. . Moreover, since the mounting depth with respect to the mounting part 11 of the conveyor belt CB becomes shallow, the effect which regulates the motion of the conveyor belt CB in the rolling direction becomes small. When the arc length L of the mounting portion 11 is larger than 45% of the outer peripheral length of the wound-up conveyor belt CB, the size and weight of the holder 1 become excessive.

  Although the outer peripheral length of the conveyor belt CB is various, it is about 1500 mm-3600 mm, for example. The width of the conveyor belt CB is, for example, about 300 mm to 3200 mm. The weight of the wound conveyor belt CB is, for example, about 1000 kg to 32000 kg.

  In the first embodiment, a pair of connecting members 20 are provided at each end of the cradle 10. In this case, as shown in FIG. 2, the pair of connecting members 20, 20 are connected so that the connecting portion with the winding core C has an apex angle, and the apex angle θ is set to 30 ° to 120 °. It is preferable. Thereby, the load of conveyor belt CB can be disperse | distributed effectively and the deformation | transformation of the holder 1 can be prevented. Furthermore, it contributes to alleviation of the load burden of the connecting member 20. If the angle θ is smaller than 30 °, the pair of connecting members 20 and 20 are too close to each other, so that it is substantially the same as that fixed by one connecting member 20, and the load on the conveyor belt CB is effectively dispersed. It becomes difficult. If the angle θ is larger than 120 °, the fixing point for fixing the connecting member 20 and the cradle 10 is close to the end of the cradle 10, so that the load on the end of the cradle 10 increases and deformation occurs. It becomes easy.

  The cradle 10 is preferably provided with a fork toe tip insertion portion 13 of a forklift as illustrated in FIGS. Thereby, conveyance of the holder 1 becomes easy.

  The holder 1 of the present invention is not limited to the first embodiment, and may be, for example, the second to fifth embodiments described below. Note that configurations not particularly mentioned in the description of the second to fifth embodiments are the same as those of the first embodiment. Various arrangements described in the first embodiment can be similarly performed in the second to fifth embodiments.

  In the second embodiment illustrated in FIGS. 4 to 5, the cradle 10 (mounting portion 11) has a plate-like body having a concave curved surface 11 b that is curved in an arc shape along the outer peripheral surface of the wound conveyor belt CB. It is comprised by. The grounding portion 12 is configured by providing a pair of a plurality of pillars 12b extending downward from the lower surface of the curved plate-like body and a grounding board 12c extending so as to connect the lower ends of the plurality of pillars 12b. ing.

  Thereby, the effect similar to 1st Embodiment can be acquired. Since the grounding portion 11 includes the pillar 12b and the grounding plate 12c, the gap between the adjacent pillars 12b can be used as the fork toe tip insertion portion 13 of the forklift.

  Since the volume of the cradle 10 can be reduced, it is advantageous for weight reduction and compactness. The cradle 10 may be formed by arranging a large number of thin plate materials curved in an arc shape in the width direction of the cradle 10 (the axial direction of the winding core C).

  In the third embodiment illustrated in FIG. 6, the mounting portion 11 is configured by arranging a plurality of strip-shaped plate materials 11 c extending in the width direction of the cradle 10 so that the long sides of the plate materials 11 c are in contact with each other. The mounting portion 11 has a polygonal shape along the outer peripheral surface of the wound-up conveyor belt CB, but becomes a substantial arc shape by increasing the number of plate members 11c. In the present invention, such a polygonal shape is also referred to as an arc shape. Therefore, the same effect as that of the first embodiment can be obtained. The fork toe tip insertion portion 13 may be provided on either the width direction side portion of the cradle 10 or the side portion orthogonal thereto, or both.

  The fourth embodiment illustrated in FIG. 7 is a modification of the grounding portion 12 of the second embodiment. The grounding portion 12 is composed of a pair of leg portions 12d that protrude downward from the lower surface of the curved plate-shaped cradle 10 and are spaced apart in the circumferential direction. The leg portion 12 d is formed to have a length for grounding together with the outer peripheral surface of the cradle 10. As a result, when the cradle 10 is placed on a flat surface, the cradle 10 is kept stationary at a fixed position.

  8 and 9 show modifications of the connecting member 20. These connecting members 20 include a length adjusting unit that adjusts the connecting length.

  A connecting member 20 illustrated in FIG. 8 includes a plate member 21 having a plurality of bolt holes 23 in the longitudinal direction and bolts 22. The plate member 21 is bridged between the receiving base 10 and the winding core C, and the connecting member 20 and the receiving base 10, and the connecting member 20 and the winding core C are fixed to the bolt holes 23 through the bolts 22, respectively. The connection length can be adjusted by appropriately selecting the bolt hole 23 through which the bolt 22 is passed from the plurality of bolt holes 23.

  The connecting member 20 illustrated in FIG. 9 includes a plate member 21 and a bolt 22 having an elongated bolt hole 23 extending in the longitudinal direction. The plate member 21 is bridged between the receiving base 10 and the winding core C, and the connecting member 20 and the receiving base 10, and the connecting member 20 and the winding core C are fixed to the elongated bolt holes 23 through the bolts 22, respectively. Since the fixing position of the bolt 22 passed through the elongated bolt hole 23 can be arbitrarily selected in the longitudinal direction of the bolt hole 23, the connection length can be adjusted.

  In the connecting member 20 illustrated in FIGS. 8 and 9, versatility is enhanced because it is possible to hold the conveyor belt CB having a different winding outer diameter without replacing the connecting member 20.

A support shaft connecting member 40 that connects the corresponding ends of both ends and the both ends of the support shaft 30 and a connecting member 20 that connects the cradle 10 and the winding core C are provided. In this embodiment, since it has the support shaft 30 and the support shaft connection member 40 which penetrate the winding core C to a core-axis direction, the winding cores C1 and C2 of several conveyor belts CB1 and CB2 are carried out by the support shaft 30. By penetrating and holding, a plurality of conveyor belts CB1 and CB2 can be held by one holder 1. Since the winding cores C1 and C2 of the conveyor belts CB1 and CB2 are respectively connected to the cradle 10 by the connecting member 20, the axial movement of the conveyor belts CB1 and CB2 is restricted by the connecting member 20, and a plurality of conveyors The belts CB1 and CB2 can be stably held.

  In addition to holding a plurality of conveyor belts CB having the same winding outer diameter, it is also possible to hold conveyor belts CB1 and CB2 having different winding outer diameters as illustrated in FIGS. In this case, the placing portion 11 is formed in an arc shape along the outer peripheral surface of the conveyor belt CB1 having the largest outer diameter.
