Abstract
A holding tool for conveyor belt conveyance for holding a conveyor belt in a wound-up state on a winding core comprises a cradle for placing a conveyor belt in a wound-up state and attaching members for attaching both ends of the cradle to both corresponding ends of the winding core. Furthermore, the cradle has an arc-shaped placement section that matches the outer circumferential surface of a conveyor belt in a wound-up state, and a ground-contacting section for bringing the cradle to an immovable state at a fixed position upon the cradle being placed upon a flat surface.
Description
- The present technology relates to a holding tool for conveyor belt conveyance. More specifically, the present technology relates to a holding tool for conveyor belt conveyance capable of stable holding and conveyance of a conveyor belt while preventing deformation due to gravity and the dead weight of a conveyor belt in a wound-up state.
- In general, conveyor belts are stored and conveyed while in a state of being wound up on a winding drum. Such winding drums are known to comprise a winding core member and a pair of flange members formed into disk shapes extending from both ends of the winding core member towards the outer radial sides (See Japanese Unexamined Patent Application Publication No. 2005-206265A, for example).
- In certain cases when conveyor belts are conveyed while in a state of being wound up on such drums, the winding drums experience deformation or buckling. This particularly occurs when loading or other work employing forklifts is done, placing an excessive load upon sections at the edges of the flange members. Furthermore, if the dead weight of the winding drum is too great, then sometimes the winding drum experiences deformation simply from the winding and holding of the conveyor belt. In addition, the winding drums are roughly cylindrical, and thus are poor in stability since they easily roll when placed on a flat surface and require special means for safe conveyance.
- The present technology provides a holding tool for conveyor belt conveyance that can stably hold and convey a conveyor belt while preventing deformation due to gravity and the dead weight of a conveyor belt in a wound-up state
- A holding tool for conveyor belt conveyance of the present technology is a holding tool for conveyor belt conveyance for holding a conveyor belt in a wound-up state on a winding core, which comprises a cradle for placing a conveyor belt in a wound-up state and attaching members for attaching both ends of the cradle to both corresponding ends of the winding core. Furthermore, the cradle has an arc-shaped placement section that matches the outer circumferential surface of a conveyor belt in a wound-up state, and a ground-contacting section for bringing the cradle to an immovable state at a fixed position when the cradle is placed upon a flat surface.
- Another holding tool for conveyor belt conveyance of the present technology is a holding tool for conveyor belt conveyance for holding a conveyor belt in a wound-up state on a winding core, which comprises a cradle for placing a conveyor belt in a wound-up state, a support shaft passing through the winding core in the direction of the core axis, support shaft attaching members for attaching both ends of the cradle to both corresponding ends of the support shaft, and attaching members for attaching the cradle to the winding core. Furthermore, the cradle has an arc-shaped placement section matching the outer circumferential surface of the conveyor belt in a wound-up state, and a ground-contacting section for bringing the cradle to an immovable state at a fixed position when the cradle is placed upon a flat surface.
- As stated above, the cradle of the former holding tool for conveyor belt conveyance of the present technology has an arc-shaped placement section. Therefore, the conveyor belt is brought to a state of being supported on its surface by the arc-shaped placement section, and the localized load burden is reduced. This has the benefit of preventing deformation of the holding tool for conveyor belt conveyance. In addition, a conveyor belt in a wound-up state may be stably held since its movement in the rolling direction is restricted by the arc-shaped placement section. In addition, the stability of the holding tool for conveyor belt conveyance is ensured by the ground-contacting section since the cradle is in an immovable state at a fixed position when the cradle is placed upon a flat surface. Furthermore, a conveyor belt may be stably held since its movement in the direction of shaft is restricted by the attaching members.
- Here, as an example, the arc length of the placement section is set to 20% to 45% of the outer circumferential length of the conveyor belt in a wound-up state. By this, the load burden of the conveyor belt is spread out, making it easier to prevent deformation of the holding tool for conveyor belt conveyance. In addition, this makes it easier to restrict the movement of the conveyor belt in the rolling direction.
- A length adjusting section that adjusts the attachment length of the attaching members may be provided. By this, versatility is increased since it is possible to hold conveyor belts of different outer winding diameters instead of replacing the attaching members.
- The attaching members are provided in pairs for each end of the cradle. These pairs are attached so that attaching portions with the winding core form a vertical angle. This vertical angle may be specified as being set to 30° to 120°. This specification makes it possible to effectively distribute the load of the conveyor belt to prevent deformation of the holding tool for conveyor belt conveyance, and alleviate the load burden on the attaching members.
- Conveyance with the holding tool for conveyor belt conveyance is made easier by forklift hook tip insertion sections being provided on the cradle.
- The latter holding tool for conveyor belt conveyance of the present technology achieves the same effects as the former holding tool for conveyor belt conveyance, and may employ the same arrangements. Furthermore, it has a support shaft that passes through the winding core in the direction of the core axis, and support shaft attaching members. Thus a single holding tool for conveyor belt conveyance may hold a plurality of conveyor belts by passing through the winding cores of a plurality of conveyor belts with the support shaft.
- In addition, spacers located on the placement section may be provided. By this, relatively small-diameter conveyor belts may be stably held via the spacers when a plurality of conveyor belts of different outer winding diameters are held.

-
FIG. 1 toFIG. 3 depict a first embodiment of a holding tool for conveyor belt conveyance of the present technology (hereinafter, holding tool 1). This holding tool 1 comprises acradle 10 for placing a conveyor belt CB in a wound-up state on a winding core C and attachingmembers 20 for attaching both ends of thecradle 10 to both corresponding ends of the winding core C. - The
cradle 10 has aplacement section 11 on its top surface. Thisplacement section 11 is formed in an arc shape matching the outer circumferential surface of a conveyor belt CB in a wound-up state. On the other hand, the bottom surface of thecradle 10 has a ground-contactingsection 12 for bringing thecradle 10 to an immovable state at a fixed position when thecradle 10 is placed upon a flat surface. Furthermore, the outer circumferential surface of a conveyor belt CB in a wound-up state is covered by a polypropylene or other resin film to prevent dirt, corrosion and the like. - According to a first embodiment, the
cradle 10 has aplacement section 11 consisting ofconcave surface 11 a constituted by the machining of the top surface of rectangular steel material into an arc shape matching the outer circumferential surface of a conveyor belt CB in a wound-up state. The ground-contactingsection 12 is constituted forming aflat surface 12 a on the bottom surface of thecradle 10. - The attaching
members 20 are constituted byplate material 21. Steel, iron or other metals, hard resins, or timber may be used as material for the attachingmembers 20. According to this embodiment, two pieces ofplate material cradle 10 and the winding core C, and both ends ofplate material 21 are fixed bybolts 22 to thecradle 10 and winding core C. - The
cradle 10 in holding tool 1 of the present technology has an arc-shaped placement section 11, bringing the conveyor belt CB to a state of being supported on its surface by the arc-shaped placement section 11. Thus, it is possible to avoid an excessive load being applied to specific areas, such as during conveyance of a conveyor belt CB wound around a conventional winding drum, and to reduce the localized load burden. This is useful in preventing deformation of the holding tool 1. In addition, since the arc-shapedplacement section 11 can catch a conveyor belt CB in a wound-up state, and restrict its movement in the rolling direction, the conveyor belt CB is stably held. - The ground-contacting
section 12 ensures the stability of this holding tool 1, since thecradle 10 is in an immovable state at a fixed position when thecradle 10 is placed upon a flat surface. This further benefits stable holding of the conveyor belt CB since the movement of the conveyor belt CB, which is prone to slippage in the direction of the shaft during conveyance, is restricted by the attachingmembers 20. In addition, since the conveyor belt CB is in surface contact with theplacement section 11, the conveyor belt CB may be damaged by friction between the conveyor belt CB and theplacement section 11 when the conveyor belt CB moves in the direction of the shaft. However, since the conveyor belt CB integrated with the winding core C is restricted in moving in the direction of the shaft by the attachingmembers 20, this damage can also be avoided. - The arc length L of the
placement section 11 may be set, for example, to 20% to 45% of the outer circumferential length of the conveyor belt CB in a wound-up state. Thus, the load burden of the conveyor belt CB is spread out, making it easier to prevent deformation of the holding tool 1. In addition, this makes it easier to restrict the movement of the conveyor belt CB in the rolling direction. If the arc length L of theplacement section 11 is less than 20% of the outer circumferential length of a conveyor belt CB in a wound-up state, the load burden of the conveyor belt CB is narrower, and the effect of preventing deformation of the holding tool 1 is reduced. In addition, the placement depth of the conveyor belt CB on theplacement section 11 becomes shallower, lessening the restricting effect upon the movement of the conveyor belt CB in the rolling direction. If the arc length L of theplacement section 11 is greater than 45% of the outer circumferential length of a conveyor belt CB in a wound-up state, the size and weight of the holding tool 1 will be too greater. - The outer circumferential length of the conveyor belt CB may vary, but is, for example, about 4700 mm to 11,300 mm with outer winding diameters of about 1500 mm to 3600 mm. The width of the conveyor belt CB is, for example, about 300 mm to 3200 mm. The weight of a conveyor belt CB in a wound-up state is, for example, about 1000 kg to 32,000 kg.
- In the first embodiment, the attaching
members 20 are provided in pairs, each pair corresponding to an end of thecradle 10. In this case, as illustrated inFIG. 2 , the pair of attachingmembers members 20. If the angle θ is less than 30°, then the pair of attachingmembers member 20, making it difficult to effectively distribute its load. If the angle θ is greater than 120°, then the fixing points where the attachingmembers 20 are fixed to thecradle 10 begin to reach the ends of thecradle 10, resulting in an increased load burden upon the ends of thecradle 10 and making deformation more likely. - The
cradle 10, as depicted inFIGS. 1 and 2 , is preferably provided with forklift hooktip insertion sections 13. These make it easy to convey the holding tool 1. - The holding tool 1 of the present technology is not limited to the first embodiment, and may be any one of the second to fifth embodiments described below. Furthermore, configurations not specifically referred to in the descriptions of the second to fifth embodiments share the same configuration as the first embodiment. In addition, the various described arrangements according to the first embodiment may be similarly implemented in the second to fifth embodiments.
- In the second embodiment depicted in
FIGS. 4 and 5 , a cradle 10 (placement section 11) is constituted by a plate-like body having aconcave surface 11 b curving in an arc shape matching the outer circumferential surface of a conveyor belt CB in a wound-up state. A ground-contactingsection 11 is constituted provided with, a pair of a plurality ofsupports 12 b extending downward from the bottom surface of the curved plate-like body andground plates 12 c extending so as to be joined with the bottom ends of the plurality ofsupports 12 b. - Thus, the same effects as the first embodiment can be achieved. The ground-contacting
section 11 is constituted by thesupports 12 b and theground plates 12 c, so the gap between theadjacent supports 12 b may be utilized as forklift hooktip insertion sections 13. - The volume of this
cradle 10 may be reduced, which is useful for miniaturization and compactness. Multiple cradles 10 may be formed side-by-side in the widthwise direction of the cradle 10 (in the direction of the shaft of the winding core C) from thin plate material curved into an arc shape. - In the third embodiment depicted in
FIG. 6 , aplacement section 11 is constituted by lining up a plurality of strips ofplate material 11 c extending in the widthwise direction of acradle 10 so that the long sides of theplate material 11 c are in contact with one another. Thisplacement section 11 has a polygonal shape matching the outer circumferential surface of a conveyor belt CB in a wound-up state, and is substantially an arc shape made up of multiple pieces ofplate material 11 c. In the present technology, such polygonal shapes are also referred to as arc shapes. Consequently, the same effects as the first embodiment can be achieved. The forklift hooktip insertion sections 13 may be provided on either the widthwise side sections of thecradle 10, side sections orthogonal to them, or both. - The fourth embodiment depicted in
FIG. 7 illustrates a modification of the ground-contactingsection 12 of the second embodiment. Here a ground-contactingsection 12 is projecting downward from the bottom surface of a curved plate-like cradle 10, and is constituted from a pair ofleg sections 12 d disposed that is spaced circumferentially. Theseleg sections 12 d are both formed to have a length such that both of the leg sections and the outer circumferential surface of thecradle 10 makes contact with the ground. Thus, thecradle 10 is in an immovable state at a fixed position when thecradle 10 is placed upon a flat surface -
FIGS. 8 and 9 illustrate a Modified Example of the attachingmembers 20. These attachingmembers 20 are provided with a length adjusting section that adjusts the attachment length. - The attaching
members 20 depicted inFIG. 8 haveplate material 21 having a plurality of bolt holes 23 in the lengthwise direction andbolts 22. These pieces ofplate material 21 are suspended between thecradle 10 and the windingcore C. Bolts 22 are passed through the bolt holes 23 to fix the attachingmembers 20 to thecradle 10, and the attachingmembers 20 to the winding core C, respectively. The attachment length may be adjusted by properly selecting the bolt holes 23 through which thebolts 22 will be passed through from the plurality of bolt holes 23 provided. - The attaching
members 20 depicted inFIG. 9 haveplate material 21 having long and narrow bolt holes 23 extending in the lengthwise direction andbolts 22. These pieces ofplate material 21 are suspended between thecradle 10 and the windingcore C. Bolts 22 are passed through the long and narrow bolt holes 23 to fix the attachingmembers 20 to thecradle 10, and the attachingmembers 20 to the winding core C, respectively. The attachment length may be adjusted by selecting the fixing positions for thebolts 22 passed through these long and narrow bolt holes 23 at any position along the bolt holes 23 in the lengthwise direction. - In the attaching
members 20 depicted inFIGS. 8 and 9 , versatility is increased since it is possible to hold conveyor belts CB of different outer winding diameters without replacing the attachingmembers 20. - In the fifth embodiment depicted in
FIGS. 10 and 11 , acradle 10 for placing a conveyor belt CB in a wound-up state, asupport shaft 30 passing through a winding core C in the direction of the core axis, supportshaft attaching members 40 for attaching both ends of thecradle 10 to both corresponding ends of thesupport shaft 30, and attachingmembers 20 for attaching thecradle 10 and the winding core C are provided. In this embodiment, asupport shaft 30 passing through the winding core C in the direction of the core axis and supportshaft attaching members 40 are provided. Thus a single holding tool 1 may hold a plurality of conveyor belts CB1, CB2 by causing thesupport shaft 30 to pass through and hold winding cores C1, C2 of the plurality of conveyor belts CB1, CB2. The winding cores C1, C2 of the respective conveyor belts CB1, CB2 are each attached to thecradle 10 by respective attachingmembers 20, so the plurality of conveyor belts CB1, CB2 may be stably held since the movement of each of the conveyor belts CB1, CB2 in the rolling direction is restricted by the attachingmembers 20. - As depicted in
FIGS. 10 and 11 , not only a plurality of conveyor belts CB with the same outer winding diameter, but conveyor belts CB1, CB2 with different outer winding diameters may be held.
