  The belt 66 travels by the rotation of the motor 17 and rotates the pulley 67. The pulley 67 is rotated by the running of the belt 66 and moves the link 68. The link 68 is moved by the rotation of the pulley 67 to move the link 69. The link 70 moves together with the link 69, moves the link 71, and moves the link 72 together. The link 71 is moved by the movement of the link 70 and moves the arm 56. The link 72 moves together with the link 70 and moves the link 73. The link 73 is moved by the movement of the link 72 and moves the link 74. The link 74 is moved by the movement of the link 73 and rotates the pulley 75. The pulley 75 is rotated by the movement of the link 74 and causes the belt 76 to travel. The belt 76 travels by the rotation of the pulley 75 and rotates the rollers 44 of the belt conveyor 14.

  According to the power transmission mechanism 18 described above, power is transmitted as follows. As shown in FIG. 8A, the pusher 60 is lowered by the operation of the cylinder 61, and the pushers 62 and 63 are lowered by the operation of the cylinder 64.

  Then, as shown in FIG. 8B, the motor 17 rotates in the right direction. The belt 66 travels so as to circulate in the right direction. The pulley 67 rotates in the right direction. The link 68 moves in the lower right direction. The link 69 rotates together with the links 70 and 72 in the right direction. The link 71 moves in the right direction. Thereby, the arm 56 travels on the rail 59 in the right direction. The arm 57 is integrated with the arm 56 and travels on the rail 59 in the right direction.

  The link 73 moves upward. The link 74 rotates in the right direction. The pulley 75 rotates in the right direction. The belt 76 travels so as to circulate in the right direction. Thereby, the roller 44 of the belt conveyor 14 rotates in the right direction and causes the belt 33 to travel.

  Further, as shown in FIG. 9A, the pusher 60 is raised by the operation of the cylinder 61, and the pushers 62, 63 are raised by the operation of the cylinder 64.

  Furthermore, as shown in FIG. 9B, the motor 17 rotates in the right direction. The belt 66 travels so as to circulate in the right direction. The pulley 67 rotates in the right direction. The link 68 moves in the upper left direction. The link 69 rotates together with the links 70 and 72 in the left direction. The link 71 moves in the left direction. As a result, the arm 56 travels on the rail 59 in the left direction. The arm 57 is integrated with the arm 56 and travels on the rail 59 in the left direction.

  The link 73 moves downward. The link 74 rotates in the right direction. The pulley 75 rotates in the right direction. The belt 76 travels so as to circulate in the right direction. Thereby, the roller 44 of the belt conveyor 14 rotates in the right direction and causes the belt 33 to travel.

  Next, the effect | action of the packaging line 10 is demonstrated based on FIG. 1 and FIG. FIG. 10 is a schematic diagram for explaining the movement of the article XA1 from the bucket 22 to the belt conveyor 14. FIG. 10A shows a state in which the article XA1 moves from the bucket 22 to the belt conveyor 14, and FIG. The state which moves is shown, (C) shows the state which moves the downstream side in the belt conveyor 14. FIG.

  As shown in FIG. 10A, the plurality of articles XA1 accommodated in the grooves 25 of the bucket 22 are pushed forward by the pusher 60 and conveyed toward the belt 33 of the belt conveyor 14. As shown in FIG. 10B, the article XA1 on the belt 33 is pushed forward by the pushers 62 and 63 as the belt 33 travels, and is conveyed toward the outer packaging machine 11. Since the path formed on the belt 33 by the outer guide members 46 and 47 becomes narrower toward the outer packaging machine 11, a plurality of transports are performed on the belt 33 as shown in FIG. Article XA1 is compressed in the width direction of the passage.

  As described above, according to the integrated supply system 12, the plurality of articles XA <b> 1 are compressed in the width direction of the passage by being conveyed through the passage where the width becomes narrower toward the outer packaging machine 11. Thereby, since several articles | goods XA1 are arranged compactly, the packaging in the outer packaging machine 11 can be performed smoothly. Further, when the upper part of the article XA1 is pushed toward the outer packaging machine 11 by the pushers 62 and 63, the belt 33 on which the article XA1 is placed travels toward the outer packaging machine 11 in conjunction with the pushers 62 and 63. Even if the length of the article XA1 in the vertical direction is longer than the length of the article XA1 pushed by the pushers 62 and 63, the article XA1 collapses out of balance and falls into the outer packaging machine 11. It is unlikely that it will not be supplied correctly. Further, the packaging mode of the article XA1 is a case where the film is folded in half so as to wrap the article XA1 from the upper part, and the lower side of the film and the three sides on both sides are sealed with a sealant, Even when the protruding sealant agent deteriorates the slipperiness of the article XA1 with respect to the belt 33, the article XA1 does not need to be moved with respect to the belt 33 in the first place. There is no case of not being supplied to the outer packaging machine 11. As described above, according to the integrated supply system 12, the article XA1 can be supplied to the outer packaging machine 11 regardless of the shape or packaging mode of the article XA1.

  And the belt 33 of the belt conveyor 14 is arrange | positioned so that the attachment members 53 and 54 which attach the intermediate | middle guide members 48-52 may be bypassed. Thereby, the intermediate guide members 48 to 52 that partition the passage formed by the outer guide members 46 and 47 into a plurality of small passages can be arranged on the traveling belt 33.

  Further, since the intermediate guide members 48, 49, 52 are provided with projecting pieces 48a, 49a, 52a that project from the lower side to the side and support the lower side of the article XA1 placed on the belt 33, the packaging for packaging the article XA1. When the seal portion of the material is arranged toward the belt 33, a space for releasing the seal portion of the packaging material is formed. Thereby, the shape of the seal portion is kept straight, and the seal portion is prevented from being caught in the gap formed between the belt 33 and the intermediate guide members 48, 49, 52.

  Further, the power transmission mechanism 18 that converts the rotational power of the motor 17 that travels the belt 33 of the belt conveyor 14 into reciprocating power that travels the pushers 62 and 63 and then supplies the power to the pushers 62 and 63 is provided. The belt 33 and the pushers 62 and 63 can be operated by one power source.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and technical idea thereof.
