Description

[Detailed Description of the Invention] This invention relates to a method and device for fixing a cable winding start end on a winding drum, and a cable winding start end fixing method and device thereof.
The present invention relates to a method for fixing the winding start end of a cable to a take-up drum when the cable is wound onto a take-up drum, a device therefor, and a system for controlling the fixing device.

The conventional method for fixing the winding start end of a cable to a winding drum is to rely exclusively on human power, in which the exit portion of the cable tip led out to the outside of the collar plate through the collar plate exit hole is manually secured to the collar plate. There is a method of bending it along the outside surface and fixing this part to the outer part of the collar plate, or fixing it with a Stella pull or the like. However, this manual method has the drawback that in the case of large diameter cables, the bending rigidity is too thick and it takes a great deal of effort to bend the cables, resulting in extremely poor overall work efficiency.

In addition, as shown in FIG. 1, a conventionally used mechanical method is to press the outlet part 2 of the cable end pulled out from the outlet hole of the flange plate 1 of the winding drum and apply hydraulic pressure using a disc 101. A known method is to press and fix it to the outer surface of the collar plate 1 using, for example, a method such as a method. However, in this conventional mechanical method, (1) when the rigidity of the cable is high and the length t of the outlet part 2 is long, the tip of the outlet part 2 protrudes from the outer periphery of the collar plate 1; This causes various obstacles and inconveniences during winding rotation. In addition, (11) since the holding disk 101 presses almost the entire outlet part 2, there is a risk of damaging the cable at the outlet hole and the corner of the holding disk; Since the pressing force is applied to the relatively outer part in the radial direction, the collar plate is likely to be deformed.
This has resulted in drawbacks and problems such as obstructing the winding of the cable in an aligned manner.

The present invention has been made to eliminate such drawbacks of the prior art; 19. First, an embodiment of the present invention will be described with reference to FIGS. 2 and 8.

Facing the flange plate 1 of the winding drum, a bottle 3 inserted into the shaft hole of the flange plate 1 is rotatably supported by a bottle support base 4 so as to be perpendicular to the surface of the flange plate 1. Bintle 3
A presser plate arm 51 is slidably and rotatably attached thereto so as to extend parallel to the surface of the collar plate 1. A gear 6 is fixed coaxially with the bottle 3 at a portion of the recess and arm 51 that is penetrated by the bottle 3, and a substantially disc-shaped holding plate 5 is fixed to the free end.

The outer circumferential edge of this presser plate 5 is selected so as not to protrude beyond the outer circumferential edge of the collar plate 1.

A bending arm 7, which rotatably supports a contact roller 8 at one end thereof, is attached to approximately the center of the presser plate 5 so as to be perpendicular to the surface of the collar plate 1. In this case, the bending arm 7 is designed, for example, as a splined shaft, so that it can slide axially relative to the retaining plate 5 but is prevented from rotating relative to it. For example, a coil-shaped pressing spring 9 is attached to the end of the bending arm 1.7 opposite to the contact roller 8 through a spring case 10i, so as to press the bending arm 7 against the surface of the collar plate 1 at all times. It is configured. What you want to pour into the load regarding the bending arm 7 is the distance from the central axis of the bottle 3 to the bending arm 7, which is the distance from the center axis of the bottle 3 to the bending arm 7, which is the distance from the central axis of the bottle 3 to the bending arm 7. The radius of rotation of the arm around Bintle 3 is the 4th
As can be seen from the figure, the radius is selected to be slightly larger than the radius from the center of the nail plate 1 to the outlet hole 1A, and smaller than the radius of the collar plate 1.

A substantially hollow cylindrical push ring 12 is attached to the side surface of the gear 6 of the presser plate arm 51 via an appropriate thrust bearing 11.
are in contact. This push ring 12 is coaxially and loosely fitted to the bottle 3, and a piston rod 13A of a hydraulic cylinder 13 extending parallel to the bottle 3 is connected to the push ring 12 via its radially outwardly extending arm. connected.

A coiled return spring 31 is attached to the outer periphery of the bottle 3 between the pressure plate arm 51 and the outer surface of the collar plate 1.
When inserting the collar plate of the bottle 3, it acts to suppress the presser plate arm 51 from separating from the collar plate. Note that the reference numeral 21 indicates a solenoid valve that allows pressure fluid to enter and exit the fluid pressure cylinder 13.

A support frame 20 is fixed to the bottle support base 4, and a drive shaft 15 extending parallel to the bottle 3 is rotatably provided on the support frame 20.

At one end of the drive shaft 15 is a drive pinion 14 that meshes with the gear 6.
is fixed, and the other end is operatively connected to an induction motor 18 and an electromagnetic brake 19, which are drive sources, via an electromagnetic clutch 16. Further, the drive shaft 15 is equipped with a rotary pulse transmitter 17 for detecting the amount of rotation.
is attached.

Note that the end face 14A of the drive pinion 14 is located to the right in FIG. As is clear from the figure, a space is secured between the gear 6 and the spring case 10 through which the drive pinion 14 can pass. This is a condition for preventing mechanical interference when the holding plate arm 51 rotates, as will be understood in the section on operation described later.

Next, with reference to FIGS. 4 and 5, the operation of the above-mentioned apparatus of the present invention, that is, the method of fixing the starting end of the cable winding on the winding drum, as well as the control system of the apparatus of the present invention will be described.

FIG. 4(a) shows a standby state in which the device of the present invention is about to start operating. The holding plate arm 51 is waiting in a horizontal position, and the bending arm 7 at this time
is detected by the fixed position detection sensor 22.

The type of winding drum and the type of cable (diameter) are determined by the microcomputer shown in FIG.

(rigidity, etc.), the length t and bending angle α of the protrusion 2 to be led out from the protrusion hole of the flange plate 1 to the outer surface of the flange plate 1 are calculated and input into the sequencer device. .

The device starts operating when the end of the cable is led out from the outlet hole 1 and the length of the outlet part 2 reaches a predetermined length t. First, the piston support base 4 approaches the collar plate 1, the bottle 3 is inserted into the shaft hole of the collar plate 1, and the contact roller 8 of the bending arm 7 comes into contact with the outer surface of the collar plate 1 (Fig. 2). condition). A transmission command is issued from the sequencer device, and first, the induction motor 18 starts rotating. At this time, the electromagnetic clutch notch 16 is in a connected state, and the presser plate arm 51 starts rotating counterclockwise in FIG. 4 via the drive pinion 14 and gear 6.

When the state shown in FIG. 4(b) is reached, the bending arm 7 comes into contact with the protrusion 2 from the outside in the radial direction and begins to bend it. As shown in FIG. 4(C), the protruding portion 2 is bent sufficiently inward in the radial direction, and at this time, the tip of the protruding portion 2 begins to enter inside from the outer peripheral edge of the collar plate 1.

When the holding plate arm 51 starts rotating, the pulse transmitter 17 connected to the drive shaft 15 begins to output pulses, and the sequencer device counts these pulses and calculates the rotation angle of the holding plate arm 51, that is, when the bending arm 7 is at the cable outlet. I'm starting to measure the bending angle to bend 2. When this bending angle is calculated to be optimal by the microcomputer device and reaches the value α that has already been input into the sequencer device (the state shown in Fig. 4(d)), a command is issued from the sequencer device and the electromagnetic brake 19 is activated. The rotation of the drive shaft 15 and therefore the presser plate arm 51 is stopped, and at the same time, the induction motor 18 is also stopped. Next, a command is issued to the solenoid valve 21 and the solenoid valve 21 opens, allowing pressure fluid to flow into the fluid pressure cylinder 13 and pushing the push ring 12 to the left. The opening part 2 is pressed against the outer surface of the collar plate 1 and fixed there. This fixed part is shown in Figure 4(d).
Note that the holding plate 5 securely catches only the tip of the cable and fixes it to the collar plate 1, which is the circular part shown with diagonal lines.

Next, a command is issued from the sequencer device to set the electromagnetic clutch 16 in the "1-disengaged" state. This breaks the operational relationship between the drive pinion 14, the induction motor 18, and the electromagnetic brake 19.

After the above preparations, the winding rotation of the unwinding drum is started. Together with the collar plate 1, the presser plate 5, and hence the presser plate arm 51, gear 6, and bottle 3 also rotate. The drive pinion 14 meshing with the gear 6 also rotates, but since the electromagnetic clutch 16 is disengaged, the drive pinion 14 simply idles regardless of other devices. As already mentioned, there is no interference between the spring case 10 and the drive pinion 14, and smooth winding rotation is ensured.

An additional comment will be made regarding the structure of the bending arm 7 shown in FIGS. 4(a) to 4(d). The contact roller 8 has a shaft 8 extending coaxially with the bending arm 7, as shown for example in FIG.
1, the bending arm 7 can be rotated about the central axis of the bending arm 7. When the contact roller 8 moves along one circumference on the outer surface of the collar plate 1, the contact roller 8 itself has a small resistance. Since the bending arm 1 can take various positions, the bending arm 1 may be rotatable with respect to the holding plate 5 as shown in FIG. 6, and there is no need to use a spline shaft as already described in the embodiment.

According to this invention, (1) the outlet portion of the cable tip is bent inward from the outer peripheral edge of the collar plate and does not protrude outside, so there is no problem at all during the winding rotation of the winding drum; (11) ) Since this method securely presses and fixes only the tip of the cable exit part with the holding plate, there is no risk of damaging the cable. Since it only acts on local areas, it prevents the possibility of deformation of the collar plate.
It is possible to eliminate the drawbacks of the conventional technology, such as not interfering with the aligned winding of the cable, and furthermore, the new control system promotes automation of the drum winding work of the wire body, which saves labor. It has the effect of contributing significantly to the
