[0001]

[Industrial applications]

 The present invention relates to a packaging tool used for transporting a long conveyor belt and a conveyor belt wound in a spectacle shape (for transportation) between a pair of the packaging tools.

[0002]

[Prior art]

 When conveyor belts are used to transport coal, ores, cements, etc., the conveyor belts are usually very long, for example over several kilometers. Therefore, the conveyor belts used for this type of application consist of several conveyor belts of a fixed length spliced together, but splicing the conveyor belts together is very time-consuming, and as long as possible. It is required to use a conveyor belt to minimize the time and effort of seaming. To meet this requirement, it is necessary to transport the conveyor belt from the manufacturer to the customer while keeping the conveyor belt as long as possible.

By the way, as a packing tool for carrying a long conveyor belt, a packing tool shown in FIG. 10 has been generally adopted. That is, a so-called bobbin 21 having a circular plate 24 protruding in the radial direction at each end of the take-up drum 23 of the conveyor belt A is fixed, and a fitting opening 25 for a shaft 28 is opened at the center of the circular plate 24. It was made up of structures. Then, with the shaft 28 fitted in the fitting opening 25 of the circular plate 24, the sling wires Y are passed through both ends of the shaft 28, and the bobbin 21 is lifted by the crane C or the like through the sling wire Y. Place on top. Then, after fitting the rolling stoppers 27 on both sides of the lower end of the bobbin 21 (circular plate) to fix the bobbin 21 on the packing pallet 29, the sling wire Y is removed from the shaft 28 and the shaft 28 is pulled out. Was there.

[0004]

[Problems to be Solved by the Invention] The above-described conventional packaging tool has the following problems. During packing and loading and unloading work, the shaft had to be inserted into and removed from the bobbin insertion port, and it took time, and the bobbin could roll on the packing pallet, which was extremely dangerous. . Since the height (diameter) of the bobbin for transportation is limited due to the road traffic law, the length of the conveyor belt was also limited according to the height of the bobbin.

The present invention has been made in view of the above points, and the packing and cargo handling work can be performed without using a shaft, the work is relatively easy and the safety is high, and the conveyor belt can be used more easily than conventional packing tools. It is an object of the present invention to provide a conveyor belt packing tool and a meganet winding conveyor belt which can be increased in length (about double).

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the packaging tool of the present invention comprises: a) a pair of bobbins fixed on both sides of a winding drum, which are circular plates projecting radially, and a long conveyor belt is attached to each bobbin. A conveyor belt packing tool for packing in the form of spectacles, which is wound about the same number of times, b) An opening for inserting a rotation shaft is opened at the center of each bobbin, and c). Outward annular collars are formed on the peripheral edge of the insertion opening and the outer peripheral edge of the circular plate, respectively, and d) the tips of the annular flanges on the insertion insertion opening side and the outer peripheral edge side face each other. Each of them is bent to have an L-shaped cross section.

[0007] Like the packing tool according to claim 2, e) the bobbins are arranged side by side and are opposed to each other with a space between the annular flanges with a part of the annular flanges on the outer peripheral edge side being in contact with each other. It is desirable to provide a plurality of connectors for connecting the arc-shaped portions, and f) form arc-shaped flanges that can be joined to the arc-shaped portions of the annular flanges on both sides of each connector.

A packing tool for a conveyor belt, which is used for packing in a spectacle shape by winding it a number of times.g) Removably attaching a winding assisting tool that projects radially to the outer peripheral edge of the bobbin. It is configured to be possible.

The spectacles winding conveyor belt of the present invention (claim 4) comprises: A) a long conveyor belt for a pair of bobbins each having a circular plate projecting radially on both sides of a winding drum. , So that the number of turns of each bobbin is approximately equal, and B) one bobbin is brought close to the other bobbin so that a part of their outer peripheral edges contact each other, thereby It is wrapped around both bobbins in the shape of glasses.

[0010]

[Action]

 In the packing tool (Claim 1) having the above-mentioned configuration, the annular flanges having an L-shaped cross section on the fitting-insertion side and the outer peripheral edge side of each pair of bobbins act as reinforcing members, respectively, and Improve strength. In addition, the ring-shaped collars on the insertion / insertion side can hook the sling wires, and the bent portion at the tip of the ring-shaped collar acts as a retainer for the sling wires, so that the ring-shaped collars on the insertion / insertion side can be slid on. By hooking on, two bobbins can be hoisted at the same time by a crane without using a shaft, and can be loaded or unloaded on the platform.

To wind the conveyor belt around a pair of bobbins in the form of glasses, for example, one bobbin should be wound around the entire length of the conveyor belt, and then the other bobbin should be covered with a part of the conveyor belt and both bobbins should be wound. The winding is performed so that they are almost equal to each other, and one bobbin is brought close to the other bobbin to bring a part of the outer peripheral edge side annular collars into contact with each other. The two bobbins are connected in series by the conveyor belt extending between the bobbins while the conveyor belt is wound in the shape of glasses. When the conveyor belt is wound around the bobbin, the shaft is fitted into the fitting opening of the bobbin and the shaft is rotated together with the bobbin, as in the conventional case.

In the packing tool according to claim 2, the arc-shaped flanges of the respective coupling tools are joined to the arc-shaped portions of the pair of bobbins facing each other between the outer peripheral edge side annular collars of the pair of bobbins, and the coupling tools are fitted into the packing tool. The arcuate portion of the annular collar and the arcuate collar are connected to each other via a connecting fitting or the like. Therefore, since the pair of bobbins are more firmly integrated by the connecting tool, the bobbins do not roll or fall. In addition, the strength of the entire packing tool is increased by connecting the upper-side connecting tools and the lower-side connecting tools with the connecting rods. Moreover, the conveyor rod can be prevented from being damaged during transportation by passing the connecting rod outside the conveyor belt that extends between the pair of bobbins.

Further, in the packing tool of the present invention, before the conveyor belt is wound around a pair of bobbins in the shape of glasses, one bobbin is wound up with the entire length of the conveyor belt (twice the length wound around one bobbin), Then, part of the conveyor belt of the same bobbin (half length) is wound on the other bobbin so that the number of turns of both bobbins is approximately equal, and put into a transport state. At this time, that is, when one bobbin is wound around the entire length of the conveyor belt, and when a part of the conveyor belt of one bobbin is wound around the other bobbin, the packing tool according to claim 3. According to this, by attaching a winding assisting tool to the outer peripheral edge of one bobbin, the winding assisting tool prevents the conveyor belt from rolling and prevents the conveyor belt from being guided during winding and unwinding. To do Also, after the conveyor belt has been wound so that the numbers of turns on both bobbins are approximately the same, it can be transported by removing the winding assist tool from the bobbin.

According to the conveyor belt having the above structure (claim 4), since the two bobbins are wound about the same number of times, it is about twice as large as the conventional conveyor belt wound on one bobbin. Reach length In addition, since the part of the conveyor belt that straddles between the bobbins acts as a connecting band for the two bobbins, the bobbins are integrated and the rolling and overturning of the bobbins are prevented.

That is, outwardly facing arc-shaped collars 7a that can be joined to the arc-shaped portions of the respective annular collars 4a are formed on both sides of the coupling tool 7, respectively, and the tip portion 7b of the arc-shaped collar 7a is bent inward. Thus, the entire arc-shaped brim 7a is formed to have an L-shaped cross section. Further, a plurality of elongated holes 7c are formed at intervals at the tip end portion 7b of the arcuate flanges 7a on both sides, as shown in FIG. Further, an insertion hole 7d for a long bolt 7e serving as a connecting rod is opened at a substantially central portion of the connecting tool 7, so that the left and right connecting tools 7, 7 can be integrally connected by the long bolt 7e as shown in FIG. It is like this.

As shown in FIGS. 4 and 5, a connecting fitting 9 for connecting the arc-shaped flange 7a of the connecting tool 7 and the outer peripheral edge side annular flange 4a of the bobbin 2 is formed in a substantially J-shaped cross section. . The key portion 9b in cross section is located on (the arc portion of) the bolt insertion port 9c and the annular collar 4a communicating with the elongated hole 7c in a state of being fitted to (the arc portion of) the annular collar 4a. Screw holes 9d are formed in the long side portions 9a, respectively. Reference numeral 10a is a bolt and nut, which is inserted in series through the bolt insertion port 9c and the elongated hole 7c. 10b is a bolt which is screwed into the screw hole 9d. Further, the connecting fitting 9 is of a type that is fitted to the outer peripheral edge annular collar 4a on the bobbin 2 side, and that of the arc-shaped collar 7a on the connecting tool 7 side is such that the bolt 10a is inserted into the elongated hole 7c. Therefore, the connecting tool 7 can be mounted at an arbitrary position between the collars 4a and 7a.

Next, the procedure of the work of packing the conveyor belt A using the packing tool 1 of the above-described embodiment and loading and unloading the conveyor belt A will be described with reference to the drawings.

At this time, the rotating shaft 8 is fitted into the fitting opening 5 of the bobbin 2A, and both ends of the shaft 8 are rotatably mounted on the winder 12. It should be noted that both ends of the shaft 8 are formed to have a circular cross section even in the case of the angular shaft 8 as described above. Then, the shaft 8 is rotated by a drive device (not shown) provided in the winder 12, and the long conveyor belt A is wound around the winding drum 3 (FIG. 2) of the bobbin 2A. The shaft 8 is fitted into the fitting opening 5 of the other bobbin 2B, and is rotatably mounted on the movable take-up carriage 13 (FIG. 1 (a)).

One end of the conveyor belt A wound on one bobbin 2A is attached to the winding drum 3 of the bobbin 2B on the winding carriage 13, and a drive device (not shown) arranged on the winding carriage 13 The bobbin 2B is rotated by and wound up (FIG. 2 (b)). At this time, the drive device on the winder 12 side is used as a brake device.

When the number of turns of the conveyor belt A wound around the bobbin 2B approaches the number of turns of the conveyor belt A on the other bobbin 2A side, the annular plate 11 around the bobbin 2A is removed. Then, the winding carriage 13 is brought close to the winding machine 12, and the annular flange 4a on the outer peripheral edge side of the bobbin 2A is brought into contact with the annular flange 4a on the outer peripheral edge side of the bobbin 2B. Also, when the number of turns of the conveyor belt A on the bobbin 2A side becomes almost equal to the number of turns of the conveyor belt A on the bobbin 2B side, in other words, the outer diameter of the conveyor belt A wound on the two bobbins 2A, 2B becomes equal. At that point, the bobbin 2B is stopped from rotating and the winding operation is completed ((c) in the same figure).

Further, an outward annular flange 5a is also projectingly provided on the peripheral portion of the insertion opening 5, and the tip portion 5b of the annular flange 5a is bent outward in the radial direction. This configuration is almost the same as the packaging tool 1 of the above-mentioned embodiment, but the following points are different.

That is, in order to reduce the weight and to confirm the winding state and the unwinding state of the conveyor belt A from the outside, the circular plate 4 is provided with radial windows 4w at regular intervals in the circumferential direction. ing. Instead of opening the window 4w, the entire circular plate 4 may have a fence structure.

Further, instead of the annular board 11, a substantially fan-shaped winding assist in which an inner-diameter side arcuate flange 15 and an outer-diameter side arcuate flange 16 are connected by a plurality of U-shaped cross-section fence members 17 A plurality of tools 14 are provided. When the conveyor belt A is wound up, a plurality of corresponding screw holes 18 for bolts are formed in the inner-diameter side arcuate flanges 15 of the respective winding assisting tools 14 and the annular flange 4a of the circular plate 4 to which they are attached. The winding assisting tool 14 can be attached to and detached from the annular collar 4a with bolts 19 as required at the time of rewinding.

[Effect of device]

 As is clear from the above description, the packing tool of the present invention and the conveyor belt wound with glasses using the packing tool have the following effects. (a) Since an annular brim is provided on the peripheral edge of the shaft fitting opening at the center of the pair of bobbins, if two sling wires are attached to the annular brim, the two bobbins can be lifted at the same time by a crane without using the shaft. Since it can be moved by moving it, the packing and cargo handling work can be performed easily and in a short time compared to the conventional packing tool.

(B) Since a pair of bobbins are arranged side by side and connected to each other, compared to the conventional packing tool (one bobbin), it is hard to roll and fall, and is highly safe and transportable. Since the length of the conveyor belt can be doubled, the conveyor belt can be made longer.

(C) In the packing tool according to the second aspect, the pair of bobbins are connected by the connecting tool, so that the rolling and the falling are prevented more reliably, and the workability is further improved. To do.

(D) The packing tool according to claim 3 is used for winding or unwinding a conveyor belt having a length equal to or larger than a predetermined number of turns (usually double length) on one bobbin. , A winding aid attached to the outer peripheral edge of the bobbin prevents the conveyor belt from rolling and guiding the conveyor belt.

(E) Since the spectacle-wound conveyor belt (Claim 4) is about twice as long as the conventional conveyor belt wound around one bobbin, it can be used as a conveyor belt over several kilometers, for example. It takes about half the time to join the conventional conveyor belts. Also, since the number of joints is reduced, the strength of the entire conveyor belt is also improved. Also, the part of the conveyor belt that straddles the bobbins functions as a connecting tool for the two bobbins, and prevents the bobbins from rolling or falling.
