2. Description of the Related Art A cable rewound from a drum is towed by a towing device provided on a wire-drawing route (for example, Japanese Patent Laid-Open No. 62-144513). At that time, the wire drawing machine supporting the drum is required to perform the following two operations. The first is to assist the feeding of the cable when the wire is extended. This is because it is impossible to pull only by the pulling device provided on the wire drawing route. Secondly, when the wire drawing is stopped, that is, when the traction device in the wire drawing route is stopped, the drum rotation must be immediately stopped. Regarding the latter, JP-A-5-146015 is known. The brake drum is fixed to the center axis of the drum, and the brake shoe is operated by a cam that changes the angle according to the tension of the cable. However, there is no description corresponding to the former in this known example. Assistance from workers is always necessary when the wire is extended.

The frame of the wire drawing machine has a frame body standing upright at the front and a drum supporting column at the rear. (a) The structure is such that the motor roller is pressed against both flanges of the drum to assist the feeding of the cable. A motor roller is attached to the lower end of a drive arm pivotally attached to the front frame, and the drive arm is pressed in the drum direction via a spring. The motor roller is momentarily activated by energization to rotate the drum. Note that the motor roller can both feed and wind the cable by forward and reverse rotation, but a small torque, high-speed, large-diameter one is suitable for feeding, and a large torque, low-speed small-diameter one is suitable for winding. . In practical use, it is desired that both of them can be selectively used, but in that case, an end plate for supporting the both in parallel is provided, and the central axis thereof is pivotally supported by the drive arm.
It is configured such that it can be fixed to the drive arm at the 80-degree symmetrical position. The center shaft is positioned so that two types of motor rollers having different diameters uniformly press the drum brim.

(B) The stop of the drum is performed by pressing the brake rod against both flanges of the drum. A brake rod is fixed to one end of a brake lever whose intermediate portion is pivotally attached to a frame, and a power cylinder is exposed to the other end, and an electric signal immediately applies pressure braking. (c) A guide device, a detection arm, and a control panel are provided on the frame for determining the timing of driving and braking. The guide device gives a certain resistance to the cable to allow it to pass through a fixed position and detect its speed. One end of the detection arm is pivotally attached to the shaft of the frame body, and the other end of the detection arm is slidably engaged with the cable passing through the guide device to be extended, and swings according to the degree of tension of the cable. This swing angle can be detected by an encoder attached to the pivot. The control board determines the timing of driving and braking from both the speed and tension of the cable and gives an instruction. Since the extended cable has a curl due to the drum, the detection arm reacts excessively to the undulations. To reduce this, an appropriate weight should be attached to the detection arm.

(D) A hydraulic cylinder is incorporated in the supporting column of the drum so that it can be pushed up hydraulically. However, while the stroke of the hydraulic cylinder is limited, the drum has different diameters of different sizes. To cope with this, the following structure is adopted. Place hydraulic cylinders on the frame and set guides on both sides. An elevating rod with a plurality of pin holes drilled at an appropriate pitch is inserted vertically along a guide so that it can be pushed up by a hydraulic cylinder. Similarly, a bearing body that can be moved up and down along the guide is provided with a through hole that can be selectively pinned to the hole of the lifting rod, and a hole through which the drum central shaft can be inserted is provided on the side thereof. As an assembling procedure, first, the height of the bearing body is adjusted and the drum center shaft is inserted. Then, adjust the height of the lifting rod to pin it to the bearing body. This allows the drum to be lifted hydraulically.

DETAILED DESCRIPTION OF THE INVENTION The drawings will be described. (a) In the frame 1, a frame body 2 is provided on the front surface of a rectangular plate, and drum supporting columns S are erected on both rear sides, respectively, and a cable drum D can be carried in between the supporting columns. The drive arm 3 has an upper end pivotally attached to the frame body 2, and a motor roller M attached to the lower end. One end of the bifurcated lever 4 is pivotally attached to the middle portion of the frame body 2, the other end is connected to the middle portion of the drive arm 3 via a spring 5, and a handle 4a is provided at the bent base portion. This lever 4 is at the position shown in FIG. 3 when the construction is not yet started, and the motor roller M is the drum D.
The tsuba is not pressed. When the handle 4a is pushed at the start of construction, the spring 5 is reversed and the state shown in FIG. 1 is reached, so that the drive arm 3 is strongly pressed and the motor roller is pressed against the drum collar. When the motor roller is energized, the drum D rotates. FIG. 4 shows that two types of motor rollers M1 and M2 for feeding and winding and large and small can be selectively used, and both motor rollers are axially supported by the end plate 6. The central shaft 7 penetrates both end plates and is pivotally supported by both arms 3. The positioning pin 8 locks both end plates to the arm 3 at 180-degree symmetrical positions. The center shaft 7 is deviated from the center line between the two motor roller shafts so that they can uniformly press the drum brim. (b) The brake lever 9 is pivotally attached to the frame at an intermediate portion, and a brake rod 10 made of steel or the like is fixed to one end thereof. The power cylinder 11 faces the other end. An electric type cylinder is suitable for the power cylinder considering the convenience of moving the wire drawing machine. Since there is a commercially available product that can push out the inner cylinder connected to the nut by rotating the screw shaft with an attached motor, this is used. When the power cylinder is energized, the brake rod presses the drum brim for braking.
The power cylinder 11 may be a hydraulic cylinder, and presses the brake rod against the drum brim by the pressure oil from the hydraulic unit to brake the drum.

When the wire drawing work is stopped, the motor roller presses the drum collar, but the power supply is cut off. The brake bar keeps pressing the drum collar. When resuming the work, first, the traction device (not shown) in front of the wire-drawing route is activated, and the cable is strained. FIG. 1 shows the state at that time. As a result, the detection arm rises, the encoder of the pivot shaft detects the angle change, and the guide device detects the passing speed of the loosened cable on the drum side, and notifies each to the control panel. Therefore, the control board first commands the energization of the motor roller. The motor roller tries to rotate, but since the brake is applied, the rotation pulse is gradually increased in a stationary state. Pulse is set value (for example, about 20HZ)
When the control signal reaches, the control panel issues a brake release command, and then commands the rotational speed of the motor roller to change in accordance with the angle change of the detection arm and the passing speed of the cable. When stopping the work, first stop the traction device in front of the route. The cable slack detection arm moves down and the motor roller is stopped when the encoder reaches the lower limit setting value. The brake rod also operates simultaneously to press the drum. Even if the detection arm may not descend due to the high rigidity of the large diameter cable, the guide device detects the stop of the cable and stops the motor roller.

The motor roller is pressed against the drum collar to control the drum drive. Press the brake rod against the drum guard to brake. Since all of them are the simplest direct means, there is no fear that the action will go wrong. By making it possible to grasp the speed and tension of the cable with the guide device and the detection arm, it is possible to reliably determine the timing of driving and braking.
Further, since the motor roller can freely change the speed according to the set value, it is possible to cope with a slight change in the degree of tension.
By attaching the weight to the detection arm, the excessive reaction of the detection arm due to the winding of the cable is controlled to prevent malfunction. It was also found in a trial experiment that an unexpected effect was obtained in eliminating the undesirable small wave motion of this arm. Although a conventional screw type jack was used for the drum support pillar,
Manual rotation of the screw shaft was a heavy labor. The support column of the present invention frees the operator from this effort.
