JPH078372U - Bobbin with remaining amount display line - Google Patents

Abstract

(57) [Summary] [Purpose] To provide a bobbin that allows the remaining amount of the linear body wound on the bobbin to be estimated by checking the position on the remaining amount display line. . [Structure] A bobbin with a remaining amount display line in which a plurality of remaining amount display lines 4 are provided on an inner surface 3 of a collar of a bobbin 1.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bobbin having a line for displaying the remaining amount on the inner surface of the bobbin collar in order to know the remaining amount of the linear body wound on the bobbin from the outside.

[0002]

[Prior art]

 No conventional bobbin has a line for indicating the remaining amount on the inner surface of its brim.

[0003]

[Problems to be solved by the device]

 The conventional bobbin has the following disadvantages. I am using a filament that is wound on a bobbin, and I do not know the remaining amount accurately, so the filament may end up in the middle of use, and there is a loss that I will leave a lot of it for safety and it will be costly. Was becoming. The present invention has been made to eliminate these drawbacks.

[0004]

[Means for Solving the Problems]

 The bobbin 1 is a bobbin with a remaining amount display line having a basic structure in which a plurality of remaining amount display lines 4 are provided on the inner surface 3 of the collar. It is preferable that a plurality of the remaining amount display lines 4 are provided concentrically with the axial center of the bobbin 1 so that it can be seen from any direction when the bobbin 1 is erected. Of course, the inner surface 3 of the brim may be provided on either side of the brim or only on one side. This is because the one provided on only one side may be placed upright with the side having the remaining amount display line 4 being the lower side when used.

[0005]

[Action]

 In advance, check the weight of each remaining amount display line 4 with respect to the outer diameter of the filament wound on the bobbin. When using, the outer diameter position of the filament that is pulled up and reduced and the remaining amount display line 4 close to the outer diameter position are set by keeping the collar surface with the remaining amount display line 4 downward. Then, the remaining amount is estimated.

【Example】

 An embodiment of the present invention will be described below. As shown in FIG. 1, on the inner surface 3 of one of the collars of the bobbin 1, several remaining amount display lines 4 concentric with the body 2 are provided. In order to provide the concentric remaining amount display line 4, paint that is hard to peel off is used, or the inner surface 3 of the brim itself is cut and drawn by a lathe or the like. In general, the material of the bobbin 1 differs depending on the quality of the filament body to be wound. That is, iron is used for heavy objects such as iron wires and copper wires, and plastic is used for plastic wires and fibers. Therefore, if the material is hard such as iron, the cutting means may be better, and it is more preferable to draw the above-mentioned paint in the remaining amount display line groove formed by cutting.

Alternatively, as shown in FIG. 2, on the inner surface 3 of the collar of the bobbin 1, a plurality of linear residual amount display lines 4 concentric with the body 2 may be provided. This case is adopted when the bobbin 1 is made of plastic and is molded by using a mold that is split in two from the center of the axis. That is, the mold is such that it breaks into two in exactly half of the linear remaining amount display line 4, and since the remaining amount display line 4 is provided in the mold beforehand, there is no residue when molding the bobbin 1. It can be obtained as having a quantity display line 4. In the above description, it goes without saying that the remaining amount display line may be a solid line, a broken line or a dotted line.

[0008]

[Effect of device]

 Since the residual amount of the striatum can be estimated from the appearance, it is possible to reduce the cost by eliminating the waste of running out and leaving too much. If the remaining amount display line 4 is concentric, it can be judged from any direction.
