[Function] The bag conveyed on the bag transfer conveyer is sandwiched between the end of the bag transfer conveyer and the suction conveyer and is conveyed, and further sucked from the end of the bag transfer conveyer by the suction force of the suction conveyer and further conveyed. When this bag reaches above the intermittent transfer conveyor and is detected by the sensor, suction is stopped and the bag drops onto the intermittent transfer conveyor, and this is repeated sequentially to stack the bag on the bag receiving portion. When the number of stacked bags reaches a predetermined number, the detector detects this, the bag transfer conveyor and suction conveyor stop, the bag supply is stopped, and the intermittent transfer conveyor moves one block and intermittently moves. The empty portion of the conveyor advances below the suction conveyor, and by repeating this, the bag is divided into blocks of a predetermined number and transferred to the next step.

As shown in FIG. 4, the sensor 14 is connected to a suction control device 16, and the suction control device 16 is further connected to the suction conveyor 4. When the sensor 14 detects the bag 2 by being connected to a valve (not shown) attached to the suction pipe 15 of the suction pipe 15, the suction control device 16 closes the valve of the suction pipe 13 in the forward direction and stops the vacuum suction from the suction hole 15. Then, the bag 2 separates from the lower surface of the suction conveyor 4 and falls.

Separation walls 18 are provided on the outer surface of the intermittent transfer conveyor 5 at appropriate intervals, and bag stacking portions 19 are formed between the separation walls 18, and the bag stacking portion at the top end of the intermittent transfer conveyor 5 is formed. 19 is located below the end of the suction conveyor 4 to form a bag receiving portion 20 for receiving the falling bag 2. In addition, as shown in FIG.
A detector 21 made of a photoelectric tube for detecting that the number of bags 2 has reached a predetermined number is provided on the outer upper side of the bag receiving portion 20 of the conveyor control device 22 as shown in FIG. The conveyor control device 22 is further connected to the tubular body transfer conveyor 17, the bag transfer conveyor 3, the suction conveyor 4 and the intermittent transfer conveyor 5, respectively.

Then, the bag receiving portion 20 is detected by the detector 21.
When it is detected that the number of bags 2 stacked in the stack reaches a predetermined number, the conveyor control device 22 determines that the tubular body conveyer 1
7. The bag transfer conveyor 3 and the suction conveyor 4 are stopped to temporarily stop the supply of the bag 2 to the bag receiving section 20, and the intermittent transfer conveyor 5 is rotated so that each bag stacking section 19 sequentially moves by one block. The empty bag stacking part 19 adjacent to the rear of the bag stacking part 19 constituting the bag receiving part 20 in the rotation direction is moved to the lower end of the suction conveyor 4 to form a new bag receiving part 20. , Then, the tubular body conveyer 1
7. The bag transfer conveyor 3 and the suction conveyor 4 are operated again to restart the supply of the bag 2.

As shown in FIG. 5, above the bag stacking portion 19 located at the end of the upper surface of the intermittent transfer conveyor 5, as shown in FIG.
A bag discharging device having a vacuum pad 23 is provided,
Simultaneously with supplying the bag 2 to the bag receiving portion 20, the vacuum pad 23 vacuum-sucks the bags 2 one by one from the full-packed bag loading portion 19, sends the sucked bag 2 to the delivery roller 24, and performs the next process. It is designed to be transferred to.

Next, the operation of the bag conveying device 1 will be described. A large number of tubular bodies 9 molded by the tubular forming device are shifted by a certain size, and the reel 7 around which the polymerized tape that has been polymerized is wound is set on the reel stand 6 and the bag transporting device 1 is driven. Conveyor 17, bag transfer conveyor 3
And the suction conveyor 4 start to rotate, respectively, and the reel 7
From the above, the cylindrical body 9 rewound in a state of being overlapped with each other and having the opening edge along the conveying direction is placed on the upper surface of the cylindrical body conveyer 17 and conveyed in the direction of arrow a in FIG. . The tubular bodies 9 that have reached the lower surface of the fast-forward roller 8 are advanced at a faster speed than the tubular body transport conveyor 17, and the tubular bodies 9 are separated at regular intervals and delivered one by one to the upper surface of the bag transfer conveyor 3. , And is conveyed along the arrow b.

When the tubular body 9 reaches below the sewing machine 10,
One of the opening edges is sewn on the bottom to form the bag 2, which is further conveyed in the direction of the arrow b, and is conveyed at the end of the bag transfer conveyor 3 between the belts 11 and 12 of the suction conveyor 4. The bag 2 reaching the end of the bag transfer conveyor 3 is vacuum-sucked from the suction hole 15 of the suction pipe 13 and then the belt 1
When they are adsorbed on the lower surfaces of the nozzles 1, 12 and further conveyed in the direction of the arrow b and reach below the sensor 14, the sensor 14 detects the bag 2 and sends a signal to the suction control device 16, and the suction control device 16 causes the sensor 14 to move. When a signal is received from the device, a suction stop signal is issued to close the valve of the suction pipe 13 ahead of the traveling direction, suction is stopped, and the bag 2 falls into the bag receiving portion 20 of the intermittent transfer conveyor 5, and the bag loading portion 19 Stacked on.

When the number of accumulated bags 2 reaches a predetermined number and the detector 21 detects this, a signal is sent from the detector 21 to the conveyor control device 22, and the conveyor control device 22 receives the signal from the detector 21. Then, the tubular body conveyer 1
7. A stop signal is issued to the bag transfer conveyor 3 and the suction conveyor 4 to stop them, and at the same time, an operation signal is issued to the intermittent transfer conveyor 5 to move the intermittent transfer conveyor 5 in the direction of arrow c by one block of the bag stacking unit 19. The empty bag stacking part 19 adjacent to the bag stacking part 19 filled with the bags 2 at the rear side in the transport direction is positioned below the end of the suction conveyor 4 to form a new bag receiving part 20.

Next, the conveyor control device 22 controls the tubular body conveyer 17, the bag conveyer 3 and the suction conveyer 4.
Then, the drive signal is issued to and the bag is rotated again, and the supply of the bag 2 to the bag receiving portion 20 is restarted.

When the bag loading section 19 in which the bags 2 are fully loaded reaches the upper end portion of the intermittent moving conveyor 5 and the photoelectric tube switch (not shown) installed therein detects the bag 2, the vacuum pad 23 descends to lower the bag 2. Vacuum suction from above,
It is sent to the delivery roller 24 and transferred to the next process such as a packaging device.
