DESCRIPTION OF THE PREFERRED EMBODIMENTS A supply reel 13 is rotatably supported on a supply reel support shaft 12 of a machine frame 11. The supply reel 13 has a cutting line 1 having a substantially constant width and a substantially constant interval.
The band-shaped rubber material 15 containing the film 4 is wound over the band-shaped interlayer film 16. The cutting line 14 may be one that completely cuts the belt-like rubber material 15 or one that cuts the rubber material 15 while leaving a part thereof. The cutting line 14 is placed at a position where, for example, the weight of the sheet-like rubber material 15C to be taken out is the same.

The machine frame 11 rotatably supports a pair of draw-out rolls 18 which hold a band-shaped laminated body of a band-shaped rubber material 15 drawn out from a supply reel 13 and a band-shaped interlayer film 16. At least one of the draw-out rolls 18 is rotationally driven by a drive motor M1, and
5 and the strip-shaped interlayer film 16 are pulled out in an overlapping state.

Downstream of the pair of pull-out rolls 18 is a separation roll 19 supported by the machine frame 11 and a belt conveyor 2.
0 is provided. The belt conveyor 20 has a pair of rotating rolls 21 and an endless belt 22 wound between the pair of rotating rolls 21, and one of the rotating rolls 21 is driven to rotate by a drive motor M2.

[0010] The separation roll 19 is a rotary roll 2 on the upstream side.
1 and is rotationally driven by a drive motor M3. The interval between the pull-out roll 18 and the belt conveyor 20 (separation roll 19) is set to be larger than the interval between the cutting lines 14 formed on the belt-shaped rubber material 15, and the length of the sheet is determined by the adjacent cutting lines 14. The rubber material 15C does not engage with both the pull-out roll 18 and the separation roll 19 (the belt conveyor 20) at the same time. One of the drive motors M2 and M3 may be omitted.

A separator 24 is provided between the pull-out roll 18 and the belt conveyor 20. The separator 24 has a separation plate 25, a separation roller 26, and a take-up reel 27 for a belt-shaped interlayer film. The separation plate 25 is
When the leading end portion of the belt-shaped rubber material 15 (take-out sheet-like rubber material 15C) is sandwiched between the separation roll 19 and the belt conveyor 20, the belt-like rubber material 15 is located at a position supporting the rear end portion of the take-out sheet-like rubber material 15C. 26 is the separation plate 2
5 is located at a position where the band-like interlayer film 16 is folded back and separated from the band-like rubber material 15 at the tip end. Take-up reel 2
Reference numeral 7 denotes a device that winds the belt-like interlayer film 16 coming out of the separation roller 26, and is driven to rotate by a drive motor M4.

In the vicinity of the end of the belt conveyor 20 in the feed direction, a stopper 30 is provided which abuts on the leading end of the sheet-like rubber material 15C fed by the belt conveyor 20 and regulates the feed position. A vacuum cup 40 for sucking the rubber material 15C is provided at a position above the rubber sheet material 15C stopped by the stopper 30 as a mechanism for extracting the rubber material 15C. 15C
Is provided.

Below the transfer plane of the belt conveyor 20, a sensor 31 for detecting that the taken-out sheet rubber material 15C has entered the belt conveyor 20, and a taken-out sheet rubber material 15C stopped by the stopper 30 are provided. And a sensor 32 for detecting the presence or absence.

The drive control unit 35 controls the drive motors M1 to M4 based on the signals from the sensors 31 and 32, for example, as follows to intermittently remove the sheet-like rubber material 15C taken out from the supply reel 13. Take out. First, in the initial operation, the leading end of the strip-shaped interlayer film 16 drawn from the supply reel 13 is wound around the take-up reel 27,
A belt-like laminate of the belt-like rubber material 15 and the belt-like interlayer film 16 is sandwiched between a pair of pull-out rolls 18, and the pull-out rolls 18 are driven by the drive motor M 1, and at the same time, the drive motor M 4
Thereby, the take-up reel 27 is driven. Further, the drive motor M3 of the separation roll 19 and the drive motor M2 of the belt conveyor 20 are simultaneously driven. Then, the belt-like rubber material 15 and the belt-like interlayer film 16 are sent to the belt conveyor 20 and are separated by the separator 24 soon. The belt-like rubber material 15 is on the belt conveyor 20, and the belt-like interlayer film 16 is on the take-up reel 27. Each sent.

The leading end of the belt-like rubber material 15 is
Conveyor 2 sandwiched between the belt conveyor 20
When it reaches 0, the sensor 31 detects the belt-shaped rubber material 15. Based on the signal from the sensor 31, the drive control device 35 drives the drive motor M1 and the drive motor M2 (withdrawal roll 1).
8 and the take-up reel 27) are stopped. Then, the rearward feeding of the belt-shaped rubber material 15 is stopped, while the leading end of the belt-shaped rubber material 15 is already fed on the belt conveyor 20, so that the feeding is continued. As a result, the extracted sheet-like rubber material 15C cut along the cutting line 14 is separated from the belt-like rubber material 15 behind it and sent until it comes into contact with the stopper 30. This is detected by the sensor 32. Robot 4
1 sucks the removed sheet-like rubber material 15C which is in contact with the stopper 30 by the vacuum cup 40 and transfers it to the lower mold 44 of a molding device or a vulcanizing device.

When the take-out sheet-like rubber material 15C abutting on the stopper 30 is exhausted, the sensor 32 detects this and drives the drive motor M1 and the drive motor M4 (draw-out roll 18 and take-up reel 27) again. Hereinafter, by repeating the same operation, the take-out sheet-like rubber material 15C can be taken out intermittently from the supply reel 13. Of course,
When the sensor 32 detects that the take-out sheet-like rubber material 15C is in contact with the stopper 30, the drive motor M2
And the drive of the drive motor M3 (the conveyor 20 and the separation roll 19) is stopped, and when the take-out sheet-like rubber material 15C is taken out from the belt conveyor 20, the drive motor M2
And a sequence for driving the drive motor M3.
