Abstract

PURPOSE:To stably supply wire to stitchers of a saddle stitching machine and a side stitching machine, and enable the use of a large wire roll and the detection of remaining quantity of wire. CONSTITUTION:A wire support 1 furnished with an axis portion for mounting a bobbin 4 wound with wire 3; an arm portion 8 which is attached to a rotating body 7 installed on the axis portion over the bobbin 4 and whose end can revolve around the bobbin 4; a guide member 9 attached to the end of the rotating arm portion 8; and a feed guide member 12 for the wire 3 supplied through the guide member 9 are provided. The use of the bobbin 4 allows a wire roll to be replaced easily without tangling. As a stitcher pulls the wire 3, the rotating arm portion 8 revolves and the wire 3 is released from the bobbin. This permits the use of a large wire roll and therefore reduces the frequency of replacing the wire. The quantity of remaining wire can be detected with a sensor attached to the axis portion for detecting the presence of the wire.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire feeder for supplying wire to a stitcher such as a saddle stitching machine or a flat stitching machine.

[0002]

2. Description of the Related Art Conventionally, as a wire supply device of this type,
What is shown in FIG. 3 is generally used. In this device, an exchange guide 22 is attached to the upper surface of a disk-shaped wire base 21, and the wire base 21 is configured to rotate freely. When the stitcher is activated, the wire winding placed on the wire base 21 is wound. The wire is pulled from 23 through the feed guide member 24, and the turntable 21 is rotated accordingly to loosen the wire winding 23 so that the wire is supplied.

[0003]

In the conventional wire feeder, the wire winding is difficult to hold and easily collapses, so that it is difficult to mount the wire winding on the wire base, and there is a possibility that the wire is entangled during transportation and mounting of the wire winding. There was a problem that there is.
In addition, since it is heavy and cannot be pulled when a wire winding with a large winding amount is used, the current situation is that a wire winding with a relatively small number of windings is used. There was also a problem that the work efficiency was low due to the high cost. Further, when the wire winding is completed or when the wire is entangled to cause a supply failure, there is no alarm means for detecting these, so that there is a problem that a defective product such as a single bound book is generated.

The present invention has been made in view of the above problems, and an object of the present invention is to stably supply a wire without being entangled and to use a large-capacity wire winding. It is another object of the present invention to provide a wire supply device capable of detecting that the remaining amount of wire is small.

[0005]

In order to achieve the above object, a wire feeder according to the present invention comprises a wire base having a shaft portion for mounting a wound bobbin in a lying state,
A rotating body rotatably mounted on the shaft portion while being positioned above the bobbin mounted on the shaft portion, and a rotary arm integrally attached to the rotating body so as to extend to the outside of the bobbin. Section, a guide member having one end attached to the distal end of the rotary arm section for passing a wire from the bobbin, and a wire passing through the guide member arranged with an inlet located above the rotating body. And a feed guide member for guiding the sheet.

When it is detected that the remaining amount of the wire wound on the bobbin is small, a sensor for detecting the presence or absence of the wire is attached to the shaft portion.

[0007]

In the wire feeder of the present invention described above, when the wire is pulled by the stitcher such as the saddle stitching machine or the flat stitching machine,
The wire is unraveled while one end of the guide member attached to the tip of the rotary arm portion circulates outside the bobbin.

[0008]

EXAMPLES Next, examples of the present invention will be described. 1 and 2 show a wire supply device as an embodiment of the present invention. FIG. 1 is a perspective view and FIG. 2 is a sectional view.

As shown in FIGS. 1 and 2, a wire base 1 is provided with an upright shaft portion 2, and a bobbin 4 on which a wire 3 is wound is attached to the shaft portion 2 in a lying state. It is supposed to be done. The bobbin 4 is attached to the shaft portion 2 via a spacer 5 for height adjustment, and the rotating body 7 is attached to the shaft portion 2 on the upper side of the bobbin 4 via a spacer 6 for height adjustment. It is installed. The rotating body 7 has a structure in which a fixed portion 7b and a rotating portion 7c are provided on both sides of a bearing portion 7a, and the upper rotating portion 7c has a rotating arm portion that inclines downward and extends to the outside of the bobbin 4. 8 is integrally attached. Further, one end of a guide member 9 composed of a spring hose is fixed to the tip of the rotary arm portion 8.

Further, an L-shaped guide arm 10 is fixed to the wire base 1 by a mounting member 11 at a position where the rotary arm 8 does not get in the way when the rotary arm 8 rotates around the bobbin 4. A feed guide member 12 made of a spring hose is attached to an upper horizontal portion of the arm 10. Further, the inlet 12a of the feed guide member 12 is arranged so as to be located above the rotating body 7, and the other end of the guide member 9 whose one end is fixed to the rotary arm portion 8 is near below the inlet 12a. Has been extended to.

Further, in this embodiment, as shown in FIG.
A magnetic sensor 13 is attached to the shaft portion 2 of the wire base 1 so as to detect the presence or absence of the wire 3 wound around the bobbin 4.

The wire 3 wound around the bobbin 4 passes through the guide member 9 from the tip of the rotary arm 8 and comes out from the other end of the guide member 10 when the wire supply is started.
In the feed guide member 12 through the inside of the feed guide member 12 and exits from the feed guide member 12 through the wire supply device, the tip of which is a stitcher of a saddle stitching machine or a flat stitching machine. The route is determined so that

Since the wire feeder as one embodiment of the present invention is constructed in this manner, when the stitcher of the saddle stitching machine or the flat stitching machine to which the tip of the wire 3 is connected operates, the wire 3 is fed. Pulled through the guide member 12,
As a result, the wire 3 is unraveled while one end of the guide member 9 attached to the tip of the rotary arm portion 8 circulates outside the bobbin 4. Then, when the amount of the wire 3 wound around the bobbin 4 becomes small and the wire 3 adjacent to the magnetic sensor 13 is unraveled and disappears, the operator is informed of the wire replacement time by an alarm or the like.

[0014]

Since the present invention is configured as described above, it has the following effects.

By using the bobbin wound with the wire, the wire can be easily mounted on the wire base without being entangled during transportation and mounting.

By rotating the rotating arm portion provided with the guide member to loosen the wire, it is possible to use a large-capacity wire winding, so that the replacement of the wire is less and the work efficiency is improved. Can be planned.

By attaching a sensor for detecting the presence or absence of wire to the shaft portion on which the bobbin is mounted, it is possible to detect the remaining amount before the wire runs out. Can be prevented.
