Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) This invention relates to a button conveying device used, for example, when supplying buttons to a button holding member of a button sewing machine.

(Prior art) As a conventional device of this type, for example,
- As shown in Publication No. 176, a button transport passage having a width corresponding to the diameter of the button is formed on a pair of button guide members that are arranged facing each other so as to be movable toward and away from each other, and the button transport passage is The button transported along the button is held on the shutter in the closed position in the button waiting section at the end of the passage, and when the shutter is opened, it is transferred onto the button carrying body below the button waiting area, and the button carrying body is rotated. There is known a device configured to be conveyed onto a button holding member of a button sewing machine as the sewing machine moves.

In this conventional device, a pair of stoppers are fixed to the tips of both button guide members so as to restrict the button waiting portion, and by adjusting the rotation of an adjustment screw, both button guide members and the stopper can be moved closer or closer together. By moving in the direction of separation, the widths of the button transfer path and the button waiting section can be changed.

(Problems to be Solved by the Invention) However, in the conventional configuration, the pair of stoppers are fixedly supported on the button guide member and are moved and adjusted integrally with the button guide member, so that the diameter of the button If the width of the button transfer path is changed in accordance with the setting, the widthwise interval in the button waiting area will be changed accordingly, but the stopper regulation position in the front and back direction perpendicular to the width direction will not be changed, and the button waiting area will be changed. The center of the button held on standby no longer coincides with the rotation axis of the button position correction member located above it and the center of the support portion of the button delivery body located below.

For this reason, the insertion pin protruding from the support part does not fit into the hole of the button, and when adjusting the movement of the button guide member, it becomes necessary to change the position of the button carrying body in accordance with the diameter of the button. ,
There has been a problem in that the rotation of the button position correction member is not accurately transmitted to the button, so that the button hole cannot be smoothly inserted into the insertion pin, resulting in a mistake in transferring the button to the button delivery body.

Structure of the invention (Means for solving the problem) This invention was made by focusing on the above-mentioned problem, and it is possible to change the spacing of the button guide members using an adjustment member to improve the button transfer path. When adjusting the width to correspond to the diameter of the button, a plurality of button position regulating members for regulating the position of the button in the button waiting section move the same amount in the direction of approaching or separating from each other with respect to the center of the button. The center of the button that is moved by the button and is waited in the button waiting section is always aligned with the center of the support section of the button carrying body and the rotation axis of the button position correction member,
There is no need to change or adjust the position of the button carrying body or the button position correction member, and the hole of the button can be smoothly inserted into the fitting part on the support part, so that there is no need to make mistakes in transferring the button to the button carrying body. This makes it possible to perform the process accurately without any problems.

To this end, the button conveyance device of this invention includes a pair of button guide members 24A that are disposed oppositely and movable toward and away from each other so as to form a button conveyance path 9 having a width corresponding to the diameter of the button B. , 24B, a button standby part 27 that is provided corresponding to the end of the button transfer passage 9 and allows the button B to stand by in a stationary state, and a fitting part 14 that fits into the hole h of the button B, Part 27
