This suction pump operates based on a command signal from a control device (not shown). The third suction member 53 is disposed so as to be separated from the second suction member 45 with the packaging bag 3 interposed therebetween. Then, by adsorbing the opening 3 a of the packaging bag 3, the opening 3 a of the packaging bag 3 is expanded in cooperation with the second adsorption member 45.

  Note that the third suction member 53 may be configured to be displaceable in a direction toward and away from the second suction member 45. In this case, the third suction member 53 can be closer to the opening 3 a of the packaging bag 3, so that the opening 3 a of the packaging bag 3 can be easily sucked.

  Referring to FIG. 4, bag sealing mechanism 9 is provided for heat-sealing and sealing opening 3 a of packaging bag 3 with belt 2 inserted therein. The bag sealing mechanism 9 is disposed adjacent to the sealing position P3. As described above, the sealing position P3 is a position when the revolving body 46 revolves the packaging bag 3 from the insertion position P2 around the revolving center axis 47 by a predetermined amount (for example, 90 degrees).

  The bag sealing mechanism 9 is disposed adjacent to the revolving body 46, and includes a pressure contact portion 54, a heater (not shown), and an elevating mechanism 55 that raises and lowers the pressure contact portion 54 and the heater. The bag sealing mechanism 9 descends when the packaging bag 3 is sent, presses the opening 3a by the pressure contact portion 54, and heats the heater of the packaging bag 3 disposed at the sealing position P3.

The discharge unit 10 includes a conveyor 56 that is driven by an electric motor (not shown). The conveyor 56 is configured to receive the packaging bag 3 dropped from the revolving body 46 and to transport the packaging bag 3 containing the belt 2. The electric motor that drives the conveyor 56 operates based on a command signal from a control device (not shown).

  Next, the operation of the above-described belt bagging apparatus 1 will be described. First, prior to the start of the operation of the belt bagging device 1, the packaging bag 3 is placed on the bag stocker 42 by the operator H, and the rotation support members (11 a, 11 b, 11 c) of the plurality of hooks 13 are placed. The belt 2 is hung on the hook 13 located below the belt. From this state, the operation of the belt bagging apparatus 1 is started.

  Then, the belt bagging device 1 is operated based on a command signal from a control device (not shown), so that the operation of inserting the belt 2 into the packaging bag 3 is automatically performed. In the following description, one belt 2 is sent from the hook 13 and inserted into the packaging bag 3, and then, the packaging bag 3 containing the belt 2 is heat-welded, and then the packaging bag after heat-welding. The process in which 3 is discharged to the conveyor 56 will be described with reference to the drawings.

  1 and 2, when the operation of the belt bagging apparatus 1 is started, first, the rotation support member 11a of the belt transport mechanism 4 is rotationally driven, and the first transport member 12 is driven. . As a result, the hook 13 that holds the belt 2 is transported in the transport direction D <b> 1 together with the first transport member 12.

  As shown in FIG. 2, the hook 13 that has reached the rotation support member 11c on the downstream side in the transport direction D1 rotates around the rotation support member 11c. For this reason, the latching | locking part 20 of this hook 13 changes direction from the horizontal state to the inclined state. As a result, the belt 2 naturally falls from the locking portion 20 due to its own weight. The tip of the second conveying member 14 is arranged in advance at the dropping position of the belt 2, and the second conveying member 14 receives the belt 2.

  The second transport member 14 that has received the belt 2 is moved in the same direction as the transport direction D1 by the transport drive mechanism 15 as shown in FIG. Accordingly, the belt 2 is moved so as to retreat from the hook 13 and is disposed at the insertion position P <b> 2 below the case 5. Thereafter, as shown in FIG. 6, the belt 2 is moved in the direction opposite to the insertion direction D2 (upward) by the second conveying member 14, and is temporarily placed at the standby position P5.

  When the belt 2 is moved in the direction opposite to the insertion direction D2 and disposed at the standby position P5, the belt 2 has a pair of opposing leg portions (24, 25) of the case 5 as shown in FIGS. It enters between and is accommodated in the case 5. At this time, the belt 2 is bent by being sandwiched between the side walls 27 of the pair of opposed leg portions (24, 25). The belt 2 is brought into frictional contact with the side walls 27 by applying an elastic repulsive force due to the bending to the side walls 27, and is held by the case 5.

  Thereafter, as shown in FIG. 8, the second conveying member 14 is displaced in the direction parallel to the conveying direction D <b> 1, thereby being displaced from the standby position P <b> 5 to the outside of the case 5, and separated from the belt 2 and the case 5. .

  Next, as shown in FIG. 9, the first adsorbing member 43 adsorbs the uppermost packaging bag 3 placed on the bag stocker 42, and the first adsorbing member 43 is moved to the swing shaft 44. Rotate around. After the first adsorbing member 43 raises the packaging bag 3, the second adsorbing member 45 sucks the packaging bag 3 and the first adsorbing member 43 sucks the packaging bag 3. To stop. As a result, the packaging bag 3 is delivered from the first suction member 43 to the second suction member 45 at the delivery position P1.

  Next, the swivel body 46 is turned 90 degrees around the turning center axis 47, whereby the packaging bag 3 is moved from the delivery position P1 to the insertion position P2 shown in FIG. In FIG. 10, illustration of the revolving body 46 and the bag guide plate 48 is omitted, and only a part of the second suction member 45 is illustrated. The opening 3 a of the packaging bag 3 arranged at the insertion position P <b> 2 is sucked by the third suction member 53 of the bag opening mechanism 7. By the cooperation of the third suction member 53 and the second suction member 45, the opening 3a of the packaging bag 3 is expanded.

  Next, the case 5 and the belt 2 are collectively inserted into the packaging bag 3. Specifically, as shown in FIG. 11, the movable portion 33b of the first linear displacement mechanism 33 of the belt insertion mechanism 8 is displaced (lowered) along the insertion direction D2. The case 5 is integrally lowered together with the movable portion 33b, and the taper portions (28, 28) of the pair of opposing leg portions (24, 25) of the case 5 pass through the opening 3a of the packaging bag 3, and the packaging bag. 3 is inserted. Furthermore, as shown in FIG. 12, most of the case 5 is inserted into the packaging bag 3. In this way, the case 5 and the belt 2 are inserted into the packaging bag 3. In FIG. 12, the first linear displacement mechanism 33 of the belt insertion mechanism 8 is not shown.

  Next, as shown in FIG. 13, the belt pushing member 35 is moved to the insertion direction D2 side by the second linear displacement mechanism 34. Accordingly, the belt 2 presses each tapered portion (28, 28) to elastically expand the case 5, and is pushed out of the case 5 through the tapered portion (28, 28). As shown in FIG.

  After the belt 2 is pushed out of the case 5, the movable portion 33b of the first linear displacement mechanism 33 moves in the upward direction opposite to the insertion direction D2, as shown in FIGS. Thereby, the case 5 is taken out from the packaging bag 3. Thereafter, as shown in FIG. 17, the movable portion 34b of the second linear displacement mechanism 34 moves upward in the direction opposite to the insertion direction D2, thereby moving the push belt 35 between the tapered portions (28, 28). Evacuate.

  After the belt 2 is inserted into the packaging bag 3, the third adsorption member 53 releases the adsorption of the packaging bag 3. Next, as shown in FIG. 18, the swivel body 46 is turned 90 degrees around the turning center axis 47 from the insertion position P2, whereby the packaging bag 3 is displaced to the sealing position P3.

  At the sealing position P3, the lifting mechanism 55 of the bag sealing mechanism 9 lowers the pressure contact portion 54 and the heater, and heat-welds the opening 3a of the packaging bag 3. The packaging bag 3 to which the opening 3a is heat-welded is moved from the sealing position P3 to the discharge position P4 by the turning of the turning body 46. At the discharge position P4, the suction of the packaging bag 3 by the second suction member 45 is released, and the packaging bag 3 is discharged onto the conveyor 56 of the discharge unit 10.

  In the belt bag filling device 1, as shown in FIG. 19, when one turning arm 51 of the turning body 46 is located at the sealing position P3, the other turning arm portion 52 is located at the delivery position P1. ing. With the above configuration, when performing the sealing operation on the packaging bag 3 held by one of the swivel arm portions 51, the other swivel arm portion 52 can perform the delivery operation of the packaging bag 3. Further, as shown in FIG. 20, when one of the swing arm portions 51 is positioned at the discharge position P4, the other swing arm portion 52 is positioned at the insertion position P2.

  With the above configuration, when the packaging bag 3 is discharged from the one turning arm portion 51 to the discharge portion 10, the case 5 and the belt 2 are inserted into the packaging bag 3 held by the other turning arm portion 52. Can be performed. Therefore, the operation of inserting the belt 2 into the packaging bag 3 can be performed twice while the revolving body 46 rotates once.

  As described above, according to the belt bag filling device 1, the belt bag filling device 1 can automate the conveyance of the belt 2, the insertion of the belt 2 into the packaging bag 3, and the sealing of the packaging bag 3. The operation of packing 2 into the packaging bag 3 can be performed more quickly. Specifically, the belt 2 is transported to the standby position P5 by the belt transport mechanism 4, and is disposed in the case 5 at the standby position P5. Next, the opening 3 a of the packaging bag 3 disposed at the insertion position P <b> 2 by the bag supply mechanism 6 is expanded by the bag opening mechanism 7. The belt insertion mechanism 8 inserts the case 5 and the belt 2 into the packaging bag 3 through the opening 3a. At this time, the pair of opposed leg portions (24, 25), particularly the tapered portions (28, 28) as the guide portions of the case 5 function as guide members for inserting the belt 2 into the packaging bag 3. For this reason, when inserting the belt 2 in the packaging bag 3, it can suppress that the belt 2 contacts the packaging bag 3, and bends carelessly, and makes the belt 2 smooth (quickly). 3 can be inserted. Since the time required to insert the belt 2 into the packaging bag 3 can be shortened, the operation of packing the belt 2 in the packaging bag can be performed more quickly.

  Therefore, according to the belt bagging apparatus 1, the operation of bagging the belt 2 can be automated, and the operation of bagging the belt 2 can be performed more quickly.

  Moreover, according to the belt bagging apparatus 1, the belt 2 can be transported to the standby position P5 more accurately by using the second transport member 14 while the belt 2 is transported quickly by the first transport member 12. As a result, the belt 2 can be accommodated in the case 5 at the standby position P5 without error, so that the bag 2 can be packed more quickly.

  Moreover, according to the belt bagging apparatus 1, the bag supply mechanism 6 holds the packaging bag 3 using the suction force of the first and second suction members (43, 45). If it is the structure using adsorption | suction force, the chucking operation | work of the packaging bag 3 and the release operation | work of a chucking are unnecessary for delivery of the packaging bag 3. FIG. Thereby, the packaging bag 3 can be quickly transferred from the first suction member 43 to the second suction member 45. Moreover, since the turning motion of the turning body 46 is a simple operation, the packaging bag 3 can be moved at a high speed by the turning body 46, and the packaging bag 3 can be quickly placed at the insertion position.

  Moreover, according to the belt bagging apparatus 1, the opening portion has a simple configuration in which the third suction member 53 of the bag opening mechanism 7 is spaced from the second suction member 45 in a state in which the packaging bag 3 is sucked. The work of expanding 3a can be performed quickly.

  Moreover, according to the belt bagging apparatus 1, since the operation | movement which rotates the turning body 46 from the insertion position P2 is a simple operation | movement, a high-speed operation | movement is realizable. Therefore, the packaging bag 3 can be quickly conveyed from the delivery position P1 to the insertion position P2, can be rapidly conveyed from the insertion position P2 to the sealing position P3 (bag sealing mechanism 9), and is further discharged from the sealing position P3. Can be transported to P4 quickly.

  Further, according to the belt bag filling device 1, the belt insertion operation into the packaging bag 3 can be guided by the pair of opposed leg portions (24, 25) disposed outside the belt 2 in the case 5. Thereby, the operation of inserting the belt into the packaging bag 3 can be performed more smoothly (quickly).

  Moreover, according to the belt bagging apparatus 1, since the belt 2 can be held by the case 5, a dedicated member for separately holding the belt 2 in the case 5 is not necessary. For this reason, in the packaging bag 3, the operation | work which takes out the belt 2 from the case 5 and the operation | work which removes the member holding the belt 2 in the case 5 from the belt 2 can be performed collectively. Thereby, the operation of inserting the belt into the packaging bag 3 can be performed more smoothly (quickly).

  Further, according to the belt bagging device 1, the second conveying member 14 is displaced to the outside of the case 5 after the belt 2 is held by the case 5. For this reason, in the operation | work which inserts the case 5 and the belt 2 in the packaging bag 3, the 2nd conveyance member 14 does not become obstructive, and the case 5 and the belt 2 can be inserted in the packaging bag 3 smoothly. Therefore, the operation of inserting the belt 2 into the packaging bag 3 can be performed more smoothly (quickly).

  Further, according to the belt bagging device 1, the case 5 and the belt 2 are inserted into the packaging bag 3 by the pair of movable legs (29, 30) of the belt insertion mechanism 8, and thereafter, the belt pushing member 35 is used. The belt 2 can be pushed out of the case 5 and can be reliably inserted deeply into the packaging bag 3. Thereby, the belt insertion mechanism 8 can perform the operation | work which takes out the case 5 from the packaging bag 3 more reliably and rapidly, inserting the belt 2 in the packaging bag 3.
