Description

  The present invention relates to a method for winding a conveyor belt, and more particularly, when a conveyor belt is wound around a metal cell, the conveyor belt can be smoothly wound without leaving an unnecessary mark at the beginning of winding. It relates to a winding method.

  In general, after manufacture, the conveyor belt is wound around a cell as its core and packed, and is directly or temporarily stored and then conveyed to a construction site. Various methods for winding the conveyor belt around the cell have been proposed (see, for example, Patent Document 1). Conventionally, when winding a conveyor belt around a metal cell, as illustrated in FIGS. 7 and 8, one end of a winding string 6 is wound around the metal cell 1 and the other end is connected to the conveyor belt B. It was made to attach to the front-end | tip part which starts winding up. Then, by rotating the metal cell 1, the conveyor belt B is wound around the metal cell 1 following the winding string 6 and wound.

  However, when the conveyor belt B is wound, the winding string 6 is already wound around the metal cell 1 in a number of times and protrudes from the outer peripheral surface of the metal cell 1. Therefore, when the conveyor belt B is drawn out from the metal cell 1 and unpacked, an uneven trace formed by the winding string 6 protruding from the outer peripheral surface of the metal cell 1 is formed on the winding start portion of the conveyor belt B. Was left. Originally, the conveyor belt B is wound up including a surplus length, but such unnecessary uneven traces are not preferable in terms of appearance quality, and the surplus length is wasted.

In the case of a wooden cell, the conveyor belt can be fixed to the outer peripheral surface of the cell by driving the fixing bracket directly into the tip of the conveyor belt so that the fixing bracket does not protrude from the conveyor belt. Further, since it is not possible to drive a fixing bracket or the like, it is not possible to adopt a fixing method such as a wooden cell.

  An object of the present invention is to provide a winding method of a conveyor belt that can be smoothly wound without leaving an unnecessary mark in a winding start portion when winding the conveyor belt around a metal cell.

  In order to achieve the above object, the conveyor belt winding method of the present invention is a conveyor belt winding method in which the conveyor belt is wound around a metal cell and packed, and the width of the conveyor belt is not less than the width of the conveyor belt supplied from the sheet supply drum. The leading end of the winding start sheet is temporarily fixed to the outer peripheral surface of the metal cell and wound and fixed one or more times, and then the winding start sheet is stretched between the metal cell and the sheet supply drum. Place the conveyor belt on top, wind the conveyor belt around the metal cell for a predetermined length so as to be sandwiched between the winding start sheet and the metal cell, then cut the winding start sheet before being wound around the metal cell. Thereafter, only the conveyor belt is wound around the metal cell.

  Here, as the winding start sheet, for example, a rubberized cloth sheet or a resin sheet having a thickness of 0.1 mm to 3.0 mm is used. Moreover, when temporarily fixing the front-end | tip part of the said winding start sheet | seat to a metal cell, an adhesive tape is used, for example.

  According to the present invention, the leading end portion of the winding start sheet having a width equal to or greater than the width of the conveyor belt supplied from the sheet supply drum is temporarily fixed to the outer peripheral surface of the metal cell, and wound and fixed one or more times. Thus, the winding start sheet does not protrude greatly locally from the outer peripheral surface of the metal cell when the conveyor belt is wound. After that, a conveyor belt is placed on the winding start sheet stretched between the metal cell and the sheet supply drum, and the conveyor belt is placed in a predetermined length so as to be sandwiched between the winding start sheet and the metal cell. After winding on the cell, the winding start sheet before being wound on the metal cell is cut, and thereafter only the conveyor belt is wound on the metal cell, so that unnecessary marks may remain at the beginning of the conveyor belt winding. And can be wound smoothly.

  Hereinafter, the winding method of the conveyor belt of this invention is demonstrated based on embodiment shown in the figure.

  In the present invention, the metal belt 1 illustrated in FIGS. 1 and 2 is wrapped with a conveyor belt B supplied from a supply source. The metal cell 1 is a hollow cylindrical body made of metal such as steel, is rotatably supported by a support base, and is configured to rotate by driving of a motor or the like. In this embodiment, the metal cell 1 is a simple cylindrical body, but the metal cell 1 having flange portions at both ends in the cylinder axis direction can also be used.

  A sheet supply drum 3 is rotatably supported on one side (right side in FIGS. 1 and 2) of the metal cell 1 on the upstream side in the supply direction of the conveyor belt B. A winding start sheet S used when the conveyor belt B starts to be wound around the metal cell 1 is wound around the sheet supply drum 3. The winding start sheet S has a width equal to or greater than the width of the conveyor belt B to be wound. Further, the metal cell 1 has a width equal to or larger than the width of the winding start sheet S.

  Examples of the material of the winding start sheet S include a rubberized cloth sheet and a resin sheet (polyethylene sheet, polypropylene sheet, etc.). The thickness of the winding start sheet S is, for example, 0.1 mm or more and 3.0 mm in order to secure necessary strength while suppressing an increase in the winding resistance to the metal cell 1 and the outer diameter at the time of winding. Set as follows.

  A support roller 2 is disposed above the sheet supply drum 3 on one side of the metal cell 1. A cutting device 4 is provided between the sheet supply drum 3 and the support roller 2.

  When the supplied conveyor belt B is wound around the metal cell 1, first, as illustrated in FIGS. 1 and 2, the sheet S starting to be wound from the sheet supply drum 3 is wound around the support roller 2. Pull out. Next, the leading end of the unrolled winding sheet S is temporarily fixed to the outer peripheral surface of the metal cell 1 by the temporary fixing means 5. The temporary fixing means 5 may be any means that has a small protrusion amount (for example, 5 mm or less) in the radial direction of the metal cell 1 when the winding start sheet S is temporarily fixed to the outer peripheral surface of the metal cell 1. An adhesive tape and similar means can be exemplified.

  Next, as illustrated in FIG. 3, the metal cell 1 is rotated to start winding, and the sheet S is wound around and fixed to the outer peripheral surface of the metal cell 1 by one or more turns. For example, the winding start sheet S is wound around the metal cell 1 by about two to four turns, and the winding start sheet S is securely fixed to the metal cell 1 by this winding.

  Next, the leading end portion of the conveyor belt B is placed on the winding start sheet S stretched between the metal cell 1 and the sheet supply drum 3 with the support roller 2 interposed therebetween. When the placed conveyor belt B is easily displaced, the conveyor belt B is fixed to the sheet S at the start of winding by a displacement preventing means that does not protrude from the surface of the conveyor belt B or has a minute protrusion amount.

  As illustrated in FIG. 4, the support roller 2 may be omitted, and the winding start sheet S may be directly supplied from the sheet supply drum 3 to the metal cell 1. And the front-end | tip part of the conveyor belt B can also be mounted on the winding start sheet | seat S stretched between the metal cell 1 and the sheet | seat supply drum 3. FIG.

  Next, in this state, the metal cell 1 is rotated as illustrated in FIG. 5, and the conveyor belt B is held at a predetermined length so as to be sandwiched between the winding start sheet S on which the conveyor belt B is placed and the metal cell 1. Just wrap it around the metal cell 1. The predetermined length of the conveyor belt B refers to, for example, a length that is wound around the metal cell 1 by 1 to 2 turns. After winding the conveyor belt B around the metal cell 1 by a predetermined length, the winding start sheet S before being wound around the metal cell 1 by the cutting device 4 is cut.

  Next, as illustrated in FIG. 6, thereafter, only the conveyor belt B is wound around the metal cell 1 to complete the winding operation.

  In the present invention, by using the winding start sheet S as described above, when the conveyor belt B is wound, the winding start sheet S does not locally protrude from the outer peripheral surface of the metal cell 1. Therefore, when the conveyor belt B is drawn out from the metal cell 1 and unpacked, unnecessary uneven traces do not remain on the winding start portion of the conveyor belt B. Therefore, the appearance quality can be prevented from being deteriorated, and the extra length is not wasted.

  In addition, since the winding is started by being placed on the winding start sheet S having a width equal to or larger than the width of the conveyor belt B, the conveyor belt B can be stably supported and can be smoothly wound around the metal cell 1. It becomes possible.
