Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a continuous delivery device that unwinds a long workpiece material wound into a coil and supplies it to a processing machine such as a press.

(Prior Art) Conventionally, there is a device in which a processed material wound into a coil is placed on a turntable and is continuously sent to a press machine or the like while being unwound by the rotation of the turntable. This continuous feeding device prevents the feeding speed of the processed material from decreasing as the winding diameter of the processed material on the turntable becomes smaller.
Equipped with a turntable rotation speed control device with a speed setting volume, the swing angle of the swing arm is changed in response to changes in the diameter of the workpiece suspended from the workpiece, and the swing angle is linked to the swing arm. The motor is controlled by controlling the speed setting volume to increase or decrease the rotation speed of the turntable and to maintain the processing material delivery speed constant (see Japanese Utility Model Application No. 59-106642).

(Problems to be solved by the invention) By the way, in the above-mentioned conventional device, the material to be processed is hung on the swinging arm immediately after being unwound, so the material, hardness, thickness, etc. of the material to be processed, The attitude of the swinging arm must be changed depending on the width, etc., to maintain a proper hanging state with the processed material, and the attitude of the swinging arm will affect the rotation speed control of the turntable. Therefore, there is a problem in that adjusting the posture of the swing arm is very troublesome. That is, the material to be processed is a strip, and when the strip is wound into a coil and placed on a turntable, the surface of the strip becomes a vertical plane. The unwound strip plate is then twisted so that the vertical plane becomes a horizontal plane by being hung on a swinging arm.

Therefore, in addition to tension, complex forces such as torsional force act on the swinging arm, and this force depends on the material of the processed material,
Varies depending on hardness etc.

Therefore, in the past, adjusting the posture of the swing arm was very important, and this adjustment required skill.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to finely adjust the posture of the tension detection arm depending on the material, hardness, thickness, width, etc. of the processed material. It is an object of the present invention to provide a continuous feeding device that can obtain a proper suspended state of a processed material and accurately detect the tension of the processed material even if the material is not loaded.

(Means for solving the problems) In order to solve the above problems, the present invention takes the following technical measures.

That is, the present invention has a coil-shaped strip processing material M placed concentrically on the upper surface of a turntable 2 which is provided on a base 1 so as to be freely rotatable around a vertical axis.

In the continuous feeding device for processed material, a guide roll 10 is provided on the upstream side of the tension detection arm 6 to hang the strip processed material M so that the strip surface becomes a horizontal plane. , the guide roll 10 is provided on a guide roll mounting post 14 disposed on the outside of the outer periphery of the turntable 2 such that its position can be adjusted in the vertical direction, and a support tube 16 into which the guide roll mounting post 14 is removably inserted is provided.
are provided at a plurality of locations on the base 1 outside the outer periphery of the turntable 2.

(Function) According to the present invention, the strip-shaped processed material M having a vertical surface that is rewound as the turntable 2 rotates is smoothly oriented by the guide roll 10 so that the vertical surface becomes a horizontal surface. After being converted,
It is hung on a tension detection arm 6 and guided to a processing machine. Therefore, the workpiece M contacts the tension detection arm 6 evenly, and the tension of the workpiece M caused by the difference in the delivery speed by the turntable 2 with respect to the supply speed to the processing machine is applied to the tension detection arm 6. accurately communicated. Also, guide roll 1
0 can be adjusted up and down, and the mounting position of the guide roll mounting support 14 can also be changed, so the optimum position can be selected depending on the material, hardness, etc. of the material to be processed.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

In the figure, 1 is a base, and 2 is a turntable, which is rotatably provided on the base 1 around a central axis (not shown), and the table 2 is driven by a motor (not shown) installed below the base. , and can be rotationally driven via drive wheels or the like.

Reference numeral 6 denotes a tension detection arm for operating the control device 3, which includes an arm body 7, a material hanging roll 8 rotatably attached to the tip of the arm body 7,
The base end of the arm body 7 is fixed, and the arm body 7 is provided with a rotation shaft 9 that is rotatably supported by the mounting box 5 so as to be rotatable about a horizontal axis, and is swingable about the rotation shaft 9. ing. A chain wheel (not shown) is wedged at the end of the rotation shaft 9 inside the detection arm mounting box. Although not shown, an endless transmission chain is hung around this chain wheel, and the transmission chain is wound around a chain foil wedged around the rotating shaft of the speed setting volume. The rotation of the shaft 9 is transmitted to a speed setting volume.

Reference numeral 10 denotes a guide roll, which is attached to the guide roll support bracket 11 so as to be rotatable around a horizontal axis, and is perpendicular to the axis of the guide roll 10 at the center of a connecting member 12 that connects the base end of the support bracket 11. A mounting tube 13 centered in the direction is fixed.

According to the above embodiment, the plurality of coil-shaped processing materials M loaded on the turntable 2 are unwound starting from the topmost one, hung on the guide roll 10 to change direction, and then After being hung on the material hanging roll 8 of the tension detection arm 6 and further changed direction, it is led to a processing machine. Therefore, the material M to be processed is guided by the guide roll 10 and is easily changed direction, and is hung on the material hanging roll 8 in a natural state without any strain, so that it is in even contact with the material hanging roll 8. Therefore, the feeding speed of the workpiece M at the beginning of unwinding is almost constant, but as the processing progresses, the coil diameter of the coiled workpiece M gradually decreases, so the feeding speed decreases, and the The applied tension increases, causing the tension detection arm 6 to swing in the direction indicated by A in FIG.

The feeding speed of the processed material M is controlled to be constant.

If the material, hardness, etc. of the processed material M changes, the relative position of the guide roll mounting column 14 with respect to the column 4 is changed, that is, the position of the support cylinder 16 is appropriately selected and the guide roll mounting column 14 is moved. In this way, the workpiece M can be properly hung on the tension detection arm 6.

When one coiled material M is sent out,
The tension caused by the workpiece M becomes zero, and the counterweight 17 automatically returns the tension detection arm 6 to its initial position.

The feeding of the material M to be processed at the next stage is carried out in the same manner as described above, and the operations are repeated in sequence.

In addition, when unwinding the wound coil-shaped processing material M from the inner winding start end, the tension detection arm 6 swings in the direction shown by arrow B in FIG. It is controlled in the decreasing direction so that it can always be supplied to the processing machine at a constant delivery speed.
