Abstract

(57) [Abstract] [Purpose] To prevent the trunk rope wound on the fixed winding drum from sliding down from the winding portion due to relaxation during the winding or feeding operation of the trunk rope in the longline fishing industry. [Structure] A vertical fixed winding drum 3 in which a trunk rope A is fed out or wound by a winding member is formed into a frustoconical shape such that the diameter of the trunk becomes smaller from the upper side, and winding is performed. Or, the taper prevents the trunk rope A being wound from sliding down from the winding body due to the sudden loosening of the trunk rope A being fed, so that the winding operation or the feeding operation can be immediately continued. .

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of a winding drum of a trunk line winding device in a longline fishery.

[0002]

[Prior art]

 In the longline fishing industry, the trunk rope winding device is designed to wind the trunk rope on the fixed winding drum with the axis kept vertical in order to prepare the trunk rope separated from the longline lifted for the next throwing. Is known, for example, as seen in Japanese Utility Model Publication No. 3-24058.

[0003]

[Problems to be solved by the device]

 The trunk rope winding device fixes the trunk rope by a winding member that rotates when winding the trunk rope. The trunk rope is tightly and uniformly wound in the up-down direction of the winding drum, and when the rope is thrown, the trunk rope is fed by a feeding machine. However, it is often the case that the winding or unwinding action has to be suddenly stopped depending on the state of the longline at the time of winding or unwinding or the working conditions. However, in the past, since the fixed winding drum was cylindrical, when the winding or unwinding action suddenly stopped, the trunk rope that was being wound or unwound relaxed, and this loosening loosened the wrapped trunk rope. A part of it slips down to the lower flange of the fixed winding drum, and in order to continue the winding and unwinding operations again, it is necessary to rewind the fallen trunk rope again. There is a problem that the operation and the feeding operation cannot be performed quickly and smoothly. An object of the present invention is to provide a winding drum that solves such problems.

[0004]

[Problems to be solved by the device]

 In order to achieve the above-mentioned object, the present invention forms a fixed winding drum whose axial line is held in a vertical direction so as to feed the trunk rope upward so that the diameter of the fixed winding drum is frustoconical so that the diameter of the drum becomes smaller. Is the gist.

[0005]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. A fixed winding drum 3 fixedly installed on a deck 1 and provided with flanges 2 at upper and lower portions thereof has its axis held vertically and its body is The frusto-conical shape is such that the body diameter is small upward and large downward. An umbrella-type guide plate 4 for guiding and guiding the trunk rope A is provided above the fixed winding drum 3, and the trunk rope A is guided by a feeding device 7 through a guide roller 5, a guide trough, a pipe 6, or the like. In order to wind the trunk rope A around the fixed winding drum 3, a known winding member (not shown), for example, as shown in Japanese Utility Model Publication No. 3-24058 is moved around the fixed winding drum 3. It is configured so that the trunk rope A, which is freely arranged and hoisted, is wound evenly and closely.

Since the embodiment of the present invention is configured as described above, during winding or unwinding of the main rope A, the winding or unwinding operation is suddenly stopped depending on the state of the longline, the working condition, and the like. Therefore, even if the trunk rope A is loosened, the taper part of the frustoconical fixed winding drum 3 prevents the trunk rope A from slipping downward, and immediately again, the winding operation or feeding of the trunk rope A is continued. The operation can be continued and the winding and unwinding work can be performed smoothly and easily.

[0007]

[Effect of device]

 The present invention is a trunk rope winding device for a long rope by a fixed winding drum that winds the trunk rope with a winding member or feeds the trunk rope upward. The vertical body of the fixed winding drum is frustoconical. Since it is formed on the fixed winding drum, the winding or unwinding operation of the trunk rope may be suddenly stopped and the trunk rope may be loosened during winding or unwinding of the trunk rope. The trunk of the trunk is prevented from sliding down due to the taper of the trunk, so that the subsequent winding or unwinding work of the trunk can be immediately and smoothly continued without labor, and It has excellent characteristics and practicality that can improve work efficiency in fisheries.
