With the swinging of 38 and 238, the pinching of the one end of the string 8 attached to the mouth portion 3b of the bag body 3 toward the tip end of the string holding bar 237 is released.

Thereafter, when the piston rod 305 of the air cylinder 304 is retracted upward, the arm 300 rotates counterclockwise in FIG. 63 with the support pin 299 as a fulcrum as the piston rod 305 of the air cylinder 304 extends. Then, the lever 297 swings in the clockwise direction in FIG. 63 with the rotation of the arm 300, and the rod 295 causes the lever 2 to move.
While the swinging motion of 97 causes the string pressing rod 16 to serve as a fulcrum, FIG.
35 in the clockwise direction, and as shown in FIG. 35, the holding claw 296 of the string pull-out clamp 19 has the notch recessed portion of the string pressing bar 16 at the other end of the string 8 attached to the mouth portion 3b of the bag body 3. Release the clamp on 294.

Next, when the piston rod 228 of the air cylinder 227 is retracted toward the vertical member 222 of the base frame 1,
The levers 225 and 225 swing in the clockwise direction of FIG. 51 around the support shaft 224 of the bracket 223 as the piston rod 228 of the air cylinder 227 retracts.
As shown in FIG.
With the swing of 5, 225, the bag holding plate 5 moves from one side to the inside of the vertical member 222 of the base frame 1, and the string winding clamp 17 returns to the original standby state as shown in FIG. .

After that, when the piston rod 266 of the air cylinder 265 is retracted toward the vertical member 261 of the base frame 1,
The levers 264 and 264 swing counterclockwise in FIG. 55 about the support shaft 263 of the bracket 262 as the piston rod 266 of the air cylinder 265 retracts, and as shown in FIG.
While moving along with the rocking motion of 4, 264, the bag holding plate 5 is moved to the inside of the vertical member 261 of the base frame 1 from the other side, and as shown in FIG. 10, the cord wrapping clamp 18 returns to the original standby state. .

Next, when the links 95 and 96 are swung in the clockwise direction in FIG. 1 with respect to the carriage 67 by an air cylinder (not shown), the base plate 97 remains horizontal while the links 95 and 96 swing. At the same time as moving from above the side frame 68 to the outside of the base frame 1, the lift truck 10
2 moves together with the base plate 97 from above the side frame 68 of the bogie 67 to the outside of the base frame 1, and the bag pressing plate 5 moves to the lifting cart 1.
02, while moving horizontally from above the support member 77 of the carriage 67 to above the side frame 68, as shown in FIG.
The top of the bag body 3 and the ears 3c and 3c
And pull out from between.

Then, when the piston rods 88, 88 of the air cylinders 87, 87 are extended along the longitudinal direction of the horizontal members 69, 69 of the side frames 68, 68 of the carriage 67, the joints 89, 89 are moved to the air cylinders 87, 87. Of the piston rods 88, 88 move horizontally, the levers 86, 86 swing in opposite directions as the joints 89, 89 move, and the support shafts 78, 78 move the levers 86, 78.
With the swing of 86, the support gears 77, 77 of the carriage 67 rotate in mutually opposite directions, and the drive gears 80, 80 rotate together with the support shafts 78, 78 in mutually opposite directions, and the driven gears. 81, 81 rotate in opposite directions while meshing with the drive gears 80, 80, and the support shafts 79, 79 together with the driven gears 81, 81 in opposite directions with respect to the support members 77, 77 of the carriage 67. When rotated, the arms 83, 83 of the holding plates 82, 82 of the bag clamps 4, 4 and the arms 85, 85 of the holding plates 84, 84 are supported by the support shafts 78, 78 and the support shafts 79, 79.
16, the holding plates 82, 84 and the holding plates 82, 84 release the holding on one side and the other side of the body portion 3a of the bag body 3, as shown in FIG. To do.

After that, when the piston rod 63 of the air cylinder 62 is retracted along the longitudinal direction of the vertical member 56 of the bag receiving base 2, the bracket 60 is fulcrumed on the support shaft 59 as the piston rod 63 of the air cylinder 62 is retracted. At the same time as rotating clockwise in FIG. 1, the movable plate 58 rotates in the clockwise direction in FIG. 1 together with the bracket 60, and the bag body 3 moves outside the bag cradle 2 along the inclination of the movable plate 58 and the chute 64. Slide down to.

[0150]

As described above, according to the device for tying a bag body according to the present invention, the bag holding body is placed on the upper part of the bag receiving stand in an upright state so that the bag holding body is a body of the bag body. Since the one side and the other side of the bag are clamped, the bag can be maintained in an upright state with respect to the bag holder by the bag clamp, and the bag pressing plate presses the upper part of the bag. The bag retainer plate can prevent the folded mouth from returning to its original state.
Since the push-up roll pushes both sides of the upper part of the bag upward, it is possible to direct one end and the other end of the cord at the mouth of the bag upward by the push-up roll, and the string-raising-and-holding-body holds the bag. Since one end and the other end of the cord of the mouth part of the body are raised in parallel with each other, the one end and the other end of the cord of the mouth part of the bag body are raised by the string raising clamp. It can be held as it is.

At the same time when the elevating frame moves up and down with respect to the base frame, the clamp holder moves downward together with the elevating frame toward the bag pressing plate. Therefore, the cord twisting clamp and the cord pull-out clamp are held together with the clamp holder. It can move toward the lifting clamp and the twisting clamp clamps one end and the other end of the cord at the mouth of the bag, so the clamp holder can only rotate 180 degrees around the vertical axis. Thus, one end and the other end of the cord at the mouth of the bag can be crossed while being clamped by the rotation of the cord twisting clamp, and the cord twisting clamp can be connected to one end of the cord at the mouth of the bag and the other. As the ends are clamped, they swing in opposite directions about the horizontal axis, so one end and the other end of the cord at the mouth of the bag body are twisted in the opposite directions as the clamp clamp swings. The string support plate can be used to connect one end and the other end of the string at the mouth of the bag. While supporting the difference part, the string pull-out pinching body oscillates in opposite directions about the horizontal axis while holding the one end and the other end of the string of the mouth part of the bag body, so that the mouth part of the bag body One end and the other end of the cord can be pulled out in mutually opposite directions with the swing of the cord pull-out holding body, and one end and the other end of the cord at the mouth of the bag can be tied.

Further, the string pressing rod presses the knot between the one end and the other end of the string at the mouth portion of the bag body against the string support plate, and the string winding sandwiching body holds one end part of the string at the mouth portion of the bag body. Since the cord is rotated around the cord retainer rod while being clamped, one end of the cord of the mouth portion of the bag body can be wound around the outer periphery of the cord retainer rod as the clamp body rotates. Since the string-wrapping sandwiching body rotates in the direction opposite to the string-wrapping sandwiching body around the string holding rod while the other end of the string at the mouth part of the bag body is sandwiched, the string at the mouth part of the bag body The other end of the cord can be wound around the outer circumference of the cord pressing rod as the clamp body rotates, and the cord pull-out clamp body can clamp the other end of the cord at the mouth of the bag body. Since it is pulled out while passing through the loop portion at one end, the one end and the other end of the string at the mouth of the bag can be firmly tied by the string pull-out sandwiching body.
