Abstract

(57) [Abstract] [PROBLEMS] To provide an improved delivery guide pulley in a wire delivery device. [Structure] In a wire rod feeding device, a shaft of a pulley base that supports a large-diameter guide pulley that guides the wire rod is fitted vertically to a horizontal support portion of a pulley base receiving stand via a bearing, and the pulley base is provided. The wire rod is configured to be passed through the hole provided in the shaft portion and to be sent out in the free direction through the guide pulley.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a delivery guide pulley of a wire delivery device.

[0002]

[Prior art]

 Hereinafter, a delivery guide of a conventional wire delivery device will be described with reference to the drawings. FIG. 3 is a side view of the wire rod feeding machine 5. The wire rod 3 wound around the bobbin 1 is configured to be fed out in a fixed right direction via a guide pulley 2 supported by the wire rod feeding machine 5. It was Further, in order to send the wire rod 3 in any direction, the double girder guide roll 4 is provided on the wire rod feeding machine 5 side as shown in FIG. 4, and the wire rod 3 from the guide pulley 2 is passed through the double girder guide roll 4. I was trying to send it out.

[0003]

[Problems to be solved by the device]

 As described above, in the conventional technical means, when the wire rod is to be fed out in the free direction, the wire rod fed out through the guide pulley is used by using the double girder guide roll. However, this method has a drawback in that the outer diameter of the double girder guide roll is limited, and the bending of the wire rod becomes abrupt, which gives stress to the wire rod to be sent out.

The present invention provides a wire-rod-dispatching machine for feeding a wire-rod in a free direction, in which the above-mentioned drawbacks of the prior art are solved and a wire-rod-dispatching guide pulley capable of guiding the wire in a free direction with a gentle bend. The purpose is to do.

[0005]

[Means for Solving the Problems]

 In this invention, the shaft of a pulley base that supports a large-diameter guide pulley that guides the wire rod in a wire rod feeding device is fitted vertically to a horizontal support portion of a pulley base receiving stand via a bearing, and A wire rod feed-out guide pulley having a free pull-out direction, which is characterized in that a wire rod is fed through a hole provided in a shaft portion of the wire rod and the wire rod is fed through the guide pulley in a free direction.

[0006]

[Action]

 In the wire rod feeding device, by supporting the shaft of the pulley base of the large-diameter guide pulley that guides the wire rod through the bearing, the pulley can freely rotate in the direction of 360 °, and the wire rod can be rotated around the shaft of the pulley base. The guide pulley can be guided in any direction by passing through the through hole.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing a wire rod feeding device of the present invention, and FIG. 2 is a sectional view showing the structure of a guide pulley rotating portion thereof. That is, the base receiving stand 8 is installed on the guide pulley 2 of the feeder 5 so that the guide pulley rotating portion of the present invention is arranged.

An upper portion of the base receiving stand 8 is a horizontal supporting portion 8a, and a bearing hole 11 is vertically formed in the center thereof, and a pulley base 6 supporting a large-diameter guide pulley 10 is provided therein. A shaft 6a provided at the bottom is rotatably fitted and supported via a bearing 7. Reference numeral 9 is a stop ring for fixing the bearing 7 to the shaft 6a of the pulley base 6.

A hole 6b is formed in the shaft 6a fitting portion of the pulley base 6 so as to vertically pass the wire rod therethrough. Therefore, the wire rod 3 sent vertically upward through the guide pulley 2 of the feeder 5 is sent out through the hole 6b through the groove provided on the outer peripheral surface of the large diameter guide pulley 10. . At this time, the guide pulley 10 is supported by the bearing 7 so that the shaft 6a of the pulley base 6 can freely rotate in the direction of 360 °, and the large diameter guide pulley can loosen the bend and send out the wire. In addition, it is possible to freely respond to any direction of sending.

[0010]

[Effect of device]

 As explained above, according to the wire rod feeding guide pulley having a free pulling direction of the present invention, the bending of the wire rod can be loosened in a free direction with a simple device using only one guide pulley having a large outer diameter. Wires can be sent out.
