Description

[Detailed description of the invention] This invention consists of a knotting mechanism on one side of the stem culm focusing space, an intermittent rotating shaft that drives this knotting mechanism, a constantly rotating shaft that transmits power to this rotating shaft, and a power transmission between both shafts. The present invention relates to a binding device that includes a clutch that connects and connects the clutch, a focused pressure sensing device that operates the clutch in conjunction with focused pressure sensing, and the like.

The purpose of this is to simplify the structure of the focused pressure sensor to sense the constant pressure of the stem culm and transmit power from the constantly rotating shaft to the intermittent rotating shaft, and to quickly and quickly The objective is to provide a device that operates accurately, has little wear and tear, and can withstand long-term use.

FIG. 1 shows an outline of the transmission system, in which the input shaft 6 detours through the focusing space A and connects the constantly rotating shaft 3 via the first transmission chain 5.
The power is transmitted from this constantly rotating shaft 3 to a transmission shaft 1 via a second transmission chain 2, and this transmission shaft 1 drives a pulling device and the like.

Further, the input shaft 6 is designed to constantly drive the packer 7 and the needle 8.

A knot 9 is provided on the side facing the needle 8, and a focused pressure sensing device 10 protruding into the focused space A is provided on this knot 9.

Figure 2 shows this focused pressure sensing device 10 and the intermittent rotating shaft 1 for nodules.
1 and the interlocking structure with the constantly rotating shaft 3.

That is, the intermittent rotating shaft 11 and the constantly rotating shaft 3 are connected so as to be relatively rotatable about the same axis, and the actuating clutch piece 12, which is slidable only in the axial direction, is externally fitted near the lower end of the intermittent rotating shaft 11. A fixed clutch piece 13 that meshes with the fixed clutch piece 13 is fixed to the upper end of the constantly rotating shaft 3.

A locking rod 14 for locking the actuating clutch piece 12 at the engagement/disengagement position is provided integrally extending from the sensing device 10, and the sensing device 10 directly locks the actuating clutch piece 12 into the axis of the intermittent rotating shaft 11. It is configured to operate in the core direction to connect and disconnect the constant rotating shaft 3 and the intermittent rotating shaft 11.

Further, a regulating cam 15 for regulating the operation of the focused pressure sensing device 10 protruding into the stem culm focusing space A is externally fitted and fixed to the intermittent rotating shaft 11.

That is, a cam follower 16 is provided on the swing shaft of the sensing device 10, and the cam follower 16 and the sensing device 10 are connected by a rod 17 so as to be slidable only in the direction in which they approach each other. They are biased in the direction of moving away from each other.

Then, the cam follower 16 is brought into sliding contact with the outer peripheral surface of the cam 15 to restrict the operation of the sensing tool 10.

A second spring 19 is interposed between the cam 15 and the actuating clutch piece 12 to urge the actuating clutch piece 12 in the axially engaging direction.

Then, the locking rod 14 is disengaged from the actuating clutch piece 12 by swinging against the first spring 18 due to the focused pressure of the sensing device 10, and the urging force of the second spring 19 causes both the clutch pieces 12, 13 to be disengaged. During one revolution of the intermittent rotating shaft 11 due to this meshing, the cam 15 retracts the sensing tool 10 from the focusing space A via the cam follower 16, and - near the end of rotation, the sensing tool 10 returns to its original position. At the same time as returning, the locking rod 14 is projected toward the operating clutch piece 12 side,
Both clutch pieces 12 are caused to ride on the locking rod 14 and resist the second spring 19.
13 to stop the rotation of the intermittent rotating shaft 11.

The intermittent rotating shaft 11 is provided with a timing gear 20 and a discharge arm, and the rotation of the timing gear 20 drives the bill and the string holder, and the string is fed by the needle 8 and knotted. A knotting section 9 is configured to hold, cut and knot the work.

In summary, the binding device of the present invention has an intermittent rotating shaft 11 for knotting operation arranged concentrically with the constantly rotating shaft 3 above the constantly rotating shaft 3, and a stem culm focusing space A in the intermittent rotating shaft 11. A regulating cam 1 that regulates the operation of the focused pressure sensing device 10 that protrudes inward.
5 is externally fitted and fixed, and below it, the intermittent rotating shaft 1
1, a fixed clutch piece 1 fixed to the upper end of the constantly rotating shaft 3
The operating clutch piece 12 that engages with the regulating cam 15 is fitted onto the outside so that it can freely slide only in the axial direction, and the operating clutch piece 12 and the regulating cam 15
A spring 19 that presses the operating clutch piece 12 downward is interposed therebetween, and the focusing pressure sensing device 10 projects into the stem culm focusing space A to prevent engagement between the operating clutch piece 12 and the fixed clutch piece 13. One end is brought into direct contact with the actuating clutch piece 12, and the actuating clutch piece 12 is actuated in the axial direction of the intermittent rotating shaft 11 by the rocking of the focused pressure sensing device 10, thereby connecting the constantly rotating shaft 3 and the intermittent rotating shaft 11. It is characterized by the fact that it is designed to be intermittently connected.

That is, since the focused pressure sensing device 10 directly operates the operating clutch piece 12 that is slidably fitted onto the intermittent rotating shaft 11, for example, a link mechanism may be connected to the focused pressure sensing device and the link mechanism may be oscillated. Compared to the case where the actuating clutch piece is actuated dynamically, the structure is simpler and the actuating clutch piece 12 is actuated to transmit power from the rotating shaft 3 to the intermittent rotating shaft 11 at all times.

Then, the operating clutch piece 12 of the intermittent rotating shaft 11 that is engaged with the fixed clutch piece 13 of the constantly rotating shaft 3 is connected to the intermittent rotating shaft 1.
Instead of increasing the outer circumferential diameter of the regulating cam 15 in the rotational radial direction and disposing it near the outer circumference of the regulating cam 15 that regulates the operation of the focused pressure sensing device 10, which is fixed to the fixed pressure sensor 10, Moreover, since it is provided around the axis of the intermittent rotating shaft 11, the outer circumferential diameter of the regulating cam 15 and the outer circumferential diameter of the fixed clutch 13 that engages with the actuating clutch piece 12 can be configured to be small, so that This has the advantage that the distance between the two can be made small and it can be mounted compactly on the aircraft body.

Moreover, since the operating clutch piece 12 is provided separately from the regulating cam 15 in the vertical direction, this is compared to, for example, a case where the operating clutch piece 12 and the regulating cam 15 are integrally configured in a continuous manner in the upward direction. Therefore, when the actuating clutch piece 12 is slid upward by the focused pressure sensing device 10, the regulating cam 15 does not create sliding resistance, and therefore the clutch can be disengaged quickly and accurately. Since it does not slide up and down, the regulating surface does not wear out and has the advantage of being durable for long-term use.

That is, when the operating clutch piece 12 and the regulating cam 15 are integrally configured, the regulating cam 15 regulates the operation of the sensing device 10 when the operating clutch piece 12 slides upward, so this regulation is prevented. Since the sliding is against the contact, it is not possible to expect the actuating clutch piece 12 to slide quickly, and therefore, not only is the clutch not able to be switched quickly, but the regulating cam is also worn due to sliding. However, by configuring the actuating clutch piece 12 and the regulating cam 15 separately, the above-mentioned drawbacks are not present.

Furthermore, by configuring the actuating clutch piece 12 to be separated from the regulating cam 15, the support for the spring 19 by which the regulating cam 15 presses the actuating clutch piece 12 downward can also be used as a member, and the structure can be simplified due to the dual use of parts. It also has the advantage of being compact.
