Description of the Related Art Conventional Problems and Problems Thereof A conventional waterproof sheet welding machine is designed to perform the hot melting necessary for welding the ends of two facing waterproof sheets by blowing hot air. Since the blowing of hot air is accompanied by a surge, it is difficult to heat two facing welded portions of the waterproof sheet. For this reason, although the two opposed welded ends of the waterproof sheet are sandwiched by the pinch rolls after the heat melting, there is a problem that welding mistakes often occur.

It is sufficient that the pinch rolls (4) can be separated from each other in one of the pairs. The open / close structure of the pinch roll (4) has a structure in which a roll (9) on the required side is attached to the tip end of an arm (9) pivotally attached to the frame (3) by an axis (8) whose axis is parallel to the axis of the pinch roll (4). The type supporting 4) can be applied. The arm (9) is rotatable about the shaft (8) in the clockwise and counterclockwise directions in FIGS. 2, 5, 6, 11, and 12. The counterclockwise rotation of the arm (9) causes the pinch roll (4) to open and separate.

On the free end side which is the other end of the leaf spring (10-1), coaxial cams (12-1) (12-1) and (12-2) having a hand-turning lever (11) at the shaft end. Is pressed against the peripheral surface of the cam (12-1) in the parallel body (see FIGS. 1, 5, and 6). The free end side, which is the other end of the leaf spring (10-2) whose one end side is fixed to the bracket (9a) connected to the arm (9), is pressed against the peripheral surface of the cam (12-2). (See Figures 1 and 12). When the pinch roll (4) is opened and separated, the hand turning lever (11) is arranged so that the lever tip (11a) side faces the rear side of the frame (3), that is, the right side in FIG. There is. Move the lever (11) 1 from this right side
When it is reversed by 80 °, the arm (9) moves to the second position via the leaf spring (10-1) by the rotation of the cam (12-1) connected to it.
The pinch roll (4) is rotated in the clockwise direction in the figure to be in the closed state (see FIG. 5). In the closed state, the pinch roll (4) is held by the cam (12-1) through the leaf spring (10-1) and the arm (9), that is, the roll pressed state is maintained. When the lever (11) is returned to the right side in FIG. 1, the displacement of the cam (12-2) along with it causes the arm (9) to pass through the plate spring (10-2) and the bracket (9a) as shown in FIG. It is rotated clockwise to release the roll pressure (see FIGS. 6 and 12). The state where the roll pressure is released is set by the cam (12-2) by the leaf spring (10-

始まる。According to the present invention, a pinch roll driving (in other words, welding machine starting) motor is formed by connecting a hot iron in a predetermined manner to a pushing member which is a spring-type driving type and whose spring-biasing driving is suppressed by a catch. The member for releasing the catch is attached to the push button for turning the switch on and off.
Since it is connected so that it can be operated by pushing down the button, if the welding machine is started by operating the push button, the hot iron occupies the position immediately in front of the pinch roll, and the waterproof sheet is welded. Thermal melting of the edges begins without time lag.

行われる。In the present invention, the movement of the hot iron due to the driving of the pushing member by the spring bias is regulated to a predetermined degree by the stopper at the fixed position. Displace to the position just before the pinch roll, and under the pinching pressure of the waterproof sheet by the pinch roll,
The displacement of the hot iron into this position causes it to break between the two facing tarpaulins. Therefore, according to the present invention, the opposing ends of the waterproof sheet can be successfully melted by the movement of the hot iron as the welding machine moves by itself. In addition, this thermal melting is achieved without any time lag when the welding machine is started, as described above, and is thus achieved in a proper manner. In addition to this, since the heat melting is performed at a position immediately before the pinch roll, the pinch roll is effectively welded after the heat melting of the end portion of the waterproof sheet.

るのである。Advantageous Effects of Invention According to the present invention as described above, the opposite ends of the waterproof sheet can be successfully heat-melted, and the pinch roll pressure following the heat-melting of the opposite sheet ends causes the sheet ends to be melted. Thus, it is possible to provide a waterproof sheet welding machine capable of reliably welding.
