Description

The present invention relates to a conveyor belt winding method and a winding drum connector used in the winding method, and more particularly, a conveyor belt that is easy to transport and handle and minimizes the use space. The winding method of this invention and the coupling tool of the winding drum used for the winding method.

  Conveyor belts used for transporting cement, coal, ore, etc. may have a total length of several kilometers or more. In such a case, it takes a lot of time to join the conveyor belts. To reduce the number of joints, make the conveyor belt as long as possible and transport it from the manufacturing plant to the site of use. The effort of splicing is reduced.

  When such a long conveyor belt is wound on a take-up drum and mounted on the platform of a transport vehicle to transport a general roadway, transport it within the range regulated by the Road Traffic Law. There is a need to. Therefore, the conveyor belt is continuously wound around a pair of winding drums and packed, and the vehicle is conveyed as long as possible within the scope of legal regulations.

  Conventionally, when a long conveyor belt is wound around a pair of winding drums, approximately half the length of the conveyor belt is wound on one winding drum and the other half is reversed on the other winding drum. I was trying to wind in the direction. Therefore, when the conveyor belt is wound around the belt conveyor device at the site of use and joined, the winding drum is used to take out one belt end of the conveyor belt from the winding center of the winding drum. The conveyor belt wound on the other side must be wound on the other winding drum.

  At that time, the other winding drum having a normal winding outer diameter of about 2.5 m to 3.0 m is wound with a conveyor belt that is twice as long as the normal winding drum. growing. Therefore, a new winding auxiliary tool such as a drum flange is required to prevent the conveyor belt from collapsing.

  As such a winding assistance tool, for example, a substantially fan-shaped winding assistance tool that matches the outer diameter of the winding drum (bobbin) has been proposed (see Patent Document 1).

However, since this winding aid is a large circular object (substantially fan-shaped), it requires a lot of labor and cost for transportation. In addition, since it is attached to the outer peripheral edges of the left and right winding drums with bolts or the like, it is troublesome to attach and detach, and since it is substantially circular, there is a problem that diversion cannot be performed if the winding drums have different sizes.

SUMMARY OF THE INVENTION An object of the present invention is to provide a conveyor belt winding method that can be easily transported and handled, and can minimize the use space, and a winding drum connector used in the winding method. .

  In order to achieve the above object, the conveyor belt winding method of the present invention winds a predetermined length of a long conveyor belt on one of a pair of winding drums provided with flange members on both sides, and winds the other winding. The ends of the coupling tool are fixed to both flange members on at least one side surface of the pair of winding drums, the remaining length of which is wound around the drum in the opposite direction, and the circumferential side surfaces are opposed to each other. Transporting in a state where the two are connected and fixed, and after transporting, the connecting tool is removed from the flange member of the other winding drum, and the fixing of the connecting tool and the flange member of the one winding drum is left as it is. The coupling tool is in a state of projecting in the outer peripheral direction of the flange member of the one winding drum, and the coupling tool takes the conveyor belt wound around the other winding drum into the one winding drum. When winding on the ram, the one winding drum protrudes from the winding outer diameter and has a length of 90% or less of the winding outer diameter. The conveyor belt wound around the other winding drum is wound up.

The winding drum coupling tool of the present invention winds up a predetermined length of a long conveyor belt on one of a pair of winding drums provided with flange members on both sides, and the remaining winding drum on the remaining winding drum. Conveyor belt that winds up in the opposite direction and fixes the end portions to both flange members on at least one side surface of the pair of winding drums facing the circumferential side surfaces, and connects and fixes both flange members. A winding drum connecting tool used for winding a winding belt, which is detachable from both flange members, and a conveyor belt wound around the other winding drum is wound around the one winding drum. said with protruding from the winding outer diameter of one of the winding drum, 90% or less of the length der of the take-up outer diameter is, and can store on the flange member of the winding drum of the one when Features It is intended.

  According to the conveyor belt winding method of the present invention, a predetermined length of a long conveyor belt is wound around one of a pair of winding drums provided with flange members on both sides, and the remaining winding drum is left with the remaining winding drum. The ends of the coupling tool are fixed to both flange members on at least one side surface of the pair of winding drums whose lengths are reversed and the circumferential side surfaces are opposed to each other, and both flange members are connected and fixed. In a stable state.

After transporting, simply remove the coupling tool from the flange member of the other winding drum, and keep the coupling tool and the flange member of one winding drum fixed, and connect the coupling tool to the flange member of one winding drum. The conveyor belt wound around the other winding drum can be wound around one winding drum along the connecting tool.

  This connector protrudes from the winding outer diameter of one winding drum when the conveyor belt wound on the other winding drum is wound on one winding drum. Even if it becomes very large, it is possible to prevent collapse and the like. Furthermore, since the length is 90% or less of the outer diameter of the winding, it is easy to transport and handle, and it is possible to minimize the use space occupied during transportation and winding.

  According to the winding drum connector of the present invention, a predetermined length of a long conveyor belt is wound around one of a pair of winding drums provided with flange members on both sides, and the remaining winding drum is left with the remaining winding drum. A conveyor belt that winds up in the opposite direction and fixes each end to both flange members on at least one side surface of a pair of winding drums that face each other on the circumferential side, and connects and fixes both flange members together. Since it is a winding drum connecting tool used for winding and is detachable from both flange members, it can be stably transported in a state where both flange members are connected and fixed by being mounted during transportation.

  Moreover, the coupling tool can be made to protrude in the outer peripheral direction of the flange member of one winding drum only by removing the coupling tool from the flange member of the other winding drum, and it is wound on the other winding drum. When the conveyor belt is wound on one winding drum, it protrudes from the winding outer diameter of one winding drum, so even if the winding outer diameter becomes very large, The conveyor belt wound around the other winding drum can be wound around the other winding drum while preventing collapse.

  Furthermore, since the length is 90% or less of the outer diameter of the winding, it is easy to transport and handle, and it is possible to minimize the use space occupied during transportation and winding.

  Hereinafter, the winding method of the conveyor belt of this invention and the coupling tool of the winding drum used for the winding method are demonstrated based on embodiment shown in the figure.

  FIG. 1 is a front view showing a packing state of a pair of winding drums 1a and 1b using the connector 6 of the present invention, and FIG. 2 is a plan view of FIG. A pair of winding drums 1a and 1b are adjacent to each other with their peripheral side surfaces facing each other, and are connected by two parallel bar-like connecting tools 6 in total, two on one side. Details of the connector 6 will be described later.

  Both winding drums 1a and 1b are provided with circular flange members 3a and 3b of a predetermined size, which are integrally fixed with reinforcing cross-shaped beams 2a and 2b on both sides, respectively. The shape of the flange members 3a and 3b is not limited to a circle.

  Rectangular insertion ports 4a and 4b are formed at the center of each winding drum 1a and 1b. A winding shaft (not shown) is inserted through the insertion openings 4a and 4b, and the respective winding drums 1a and 1b are rotated in opposite directions, whereby each winding drum 1a and 1b has a long conveyor belt. W is wound up by a predetermined length. In this embodiment, it is wound up by approximately half the length.

  The cross-shaped beams 2a and 2b attached to the respective flange members 3a and 3b have a plurality of attachment holes 5 formed at predetermined intervals at the tip portions. Fixing bolts 6b inserted through bolt holes 6a at both ends of the coupling tool 6 are fastened to the mounting holes 5, and the pair of winding drums 1a and 1b are coupled via the flange members 3a and 3b.

  In the above-described embodiment, the pair of winding drums 1a and 1b and the flange members 3a and 3b have the same specifications (shape, size, etc.), but they can also have different specifications. Further, the length of the conveyor belt W wound around each winding drum 1a, 1b is not limited to half, and the length wound at a predetermined ratio can be changed. For example, 60% length of the conveyor belt W is wound around one winding drum 1a, and the remaining 40% length is wound around the other winding drum 1b. Accordingly, the predetermined ratio is determined. Moreover, the number of the couplers 6 and the shapes of the insertion openings 4a and 4b are not limited to those shown in the embodiment.

  Next, a method for winding the conveyor belt W will be described. First, about half the length of the long conveyor belt W is wound around one winding drum 1a, and the remaining length is wound around the other winding drum 1b in the reverse direction.

  Then, each winding drum 1a, 1b is made to oppose a surrounding side surface, and both sides are connected and fixed with a total of four rod-shaped connecting tools 6, and it packs in the state shown in FIG. The package is mounted on a transport vehicle such as a truck and transported from the conveyor belt W manufacturing plant to the site of use.

  Next, the fixing bolt 6b of the flange member 3b of the other winding drum 1b fixing the connector 6 is removed to separate the winding drums 1a and 1b. And the connection tool 6 is made into the state protruded in the outer peripheral direction of the flange member 3a of one winding drum 1a as the state with fixation with the flange member of one winding drum 1a as it is. And as shown in FIG. 3, each winding drum 1a, 1b is installed in the winding base 7 for winding.

  In this state, as shown in FIG. 4, one winding drum 1a is rotationally driven to wind up the conveyor belt W wound around the other winding drum 1b. At this time, the coupler 6 projecting outward from the flange member 3a of the winding drum 1a guides the conveyor belt W to be wound.

  When the conveyor belt W wound around the other winding drum 1b is wound around the one winding drum 1a, the coupler 6 protrudes from the winding outer diameter D. Even when the length of the conveyor belt W is wound up and the winding outer diameter D becomes very large, it is possible to prevent collapse and meandering.

  Furthermore, since the length L of the coupler 6 is 90% or less of the winding outer diameter D, it is easy to transport and handle, and the use space occupied during transportation and winding can be minimized. Become. For example, the height H of the winding base 7 can be lowered. Since the connector 6 is compact in this way, the connector 6 and the associated cost reduction can be achieved.

Depending on the position where the connector 6 is fixed to the flange member 3a, the length L of the connector 6 can be set to about 20% to 80% of the winding outer diameter D, for example.
In addition, the protrusion length t of the coupler 6 from the winding outer diameter D is preferably 10% or less of the winding outer diameter D, and more preferably 5% or less.

  After all the conveyor belts W have been wound on one winding drum 1a, the belt end is pulled as shown in FIG. 5, the wound conveyor belt W is unwound and wound on a belt conveyor device (not shown). go. Even during the feeding, the connecting member 6 protruding from the flange member 3a toward the outer periphery prevents collapse or meandering due to feeding.

  As described above, the connecting tool 6 used for connecting and fixing the two winding drums 1a and 1b at the time of transportation can be easily wound and fed out by simply removing it from the flange member 3b of the other winding drum 1b. It becomes possible to function as a guide for preventing time collapse and meandering.

  After all the conveyor belt W has been unwound, as shown in FIG. 6, the fixing bolt 6b which has fixed the connecting tool 6 to the flange member 3a is loosened to rotate the connecting tool 6, and the other end side bolt hole 6a. The fixing bolt 6b is inserted through the flange member 3a. Thus, since the protrusion of the coupling tool 6 from the flange member 3a can be eliminated and the coupling tool 6 can be stored on the flange member 3a, it becomes compact and easy to handle and carry.

  The mechanism for storing the connector 6 on the flange member 3a is not limited to the illustrated one. For example, the bolt 6a can be made longer and the connector 6 can be slid. Further, the position and number of the bolt holes 6a can be arbitrarily determined so as to improve the workability at the time of connection, protrusion, and storage with the flange members 3a and 3b of the connector 6.

  FIG. 7 shows a packing state of a pair of winding drums 1a and 1b using another connector 6. FIG. The connector 6 has a flat plate shape, and corners of the four corners are machined into an arc shape. The corners are arcuate so that the conveyor belt W is not damaged.

  When the conveyor belt W wound up on the other winding drum 1b is wound around one winding drum 1a, it protrudes from the winding outer diameter D and is 90% or less of the winding outer diameter D. As long as the length is L, it is possible to adopt a shape other than the rod shape.
