At that time, the assembly is usually used to prevent damage to the ends during transportation, to prevent the pipe material from being pulled out due to loosening of the bundle, or to prevent dust from entering the pipe material during outdoor storage. Both ends are wrapped in packaging bags.

Conventionally, as one means of such packaging, a packaging method as disclosed in Japanese Patent Publication No. 56-38454, for example, has been known.

In this method, a predetermined number of long bodies (tubes) are placed on the receivers of a belt conveyor, in which receivers are arranged at appropriate intervals to accommodate a plurality of long bodies (tubes) in a final convergence state or a state close to this. After the body is put in, the body is transported by the belt conveyor, a large number of folded bags are placed on the side part of the belt conveyor, the bags are taken out one by one, the taken out bags are expanded, In this method, the bag is placed over the end of the group of elongated bodies being conveyed, and then a string is tied from above the bag.

(Problems to be Solved by the Invention) However, the above-described conventional technology has the following problems.

In other words, the outer circumferential length of the aggregate of the tube materials will naturally vary depending on the diameter and number of the tube materials, but
From the viewpoint of work efficiency and economy, only one type of packaging bag is often used, which fits the longest outer circumference.

Therefore, in most cases, when the packaging bag is placed over the end of the assembly, a large amount of excess material is left in the bag. However, in the above-mentioned conventional technology, since the string is tied from above the bag without folding the surplus portion or any other process, wrinkles may occur in the bag, and in some cases, a part of the bag may become loose when the string is tied. There was a problem in that the quality of the product was damaged due to tearing.

That is, simultaneously with the suction of the lower suction pad 44, the first and second clamp extrusion cylinders 54 of the bag clamp unit 5,
54, 55, and 55 operate, and the first and second clamps 56
, 56, 57° 57 are pushed out toward the packaging bag B. Then, the first and second clamps 56, 5 are pushed out.
When 6°57.57 reaches both side edges of packaging bag B,
The operation may be such that each of them is instantaneously closed and the both side edges are clamped.

Subsequently, the upper suction pad elevating cylinder 32, the lower suction pad elevating cylinder 42, and the first clamp extrusion cylinder 54,54 operate all at once, and the upper suction pad 34 and the lower suction pad 44 are vertically separated and used for packaging. While separating the top and bottom surfaces of bag B, the first clamp 56.5
6 presses the opening of packaging bag B from both sides. As a result, the packaging bag B is completely expanded [see FIGS. 22(a) and 22(b)]. Note that since the packaging bag B does not have a gusset, the width of the opening becomes narrower than the width of the bottom when it is expanded, but as described above, the first clamp 56 that clamps the opening .56 moves to press the opening from both sides, so the movement of the packaging bag B is not hindered. Therefore, the packaging bag B can be unfolded neatly without wrinkles.

While the packaging bag B is being expanded as described above,
The upper guide plate 63 of the guide unit 6 is located at a position slightly lower than the upper surface of the packaging bag B, and the lower guide plate 64 is located at a position slightly higher than the lower surface of the packaging bag B, and both guide plates 63
．． 64 are both waiting at a position near the opening of the packaging bag B [see FIGS. 23(a) and 23(b)].

Then, at the same time as the packaging bag B is completely expanded, the drive motor 65 of the guide unit 6 and the lower traveling carriage push-out cylinder 69 operate simultaneously, and the upper guide plate 6 is inserted into the packaging bag B.
3 and the lower guide plate 64 enter.

When the upper guide plate 63 and the lower guide plate 64 enter the packaging bag B, the upper guide plate elevating cylinder 66 and the lower guide plate elevating cylinder 68 operate together, and the inside of the upper and lower surfaces of the packaging bag B is activated. The upper guide plate 63 and the lower guide plate 64 are in contact with the upper guide plate 63 and the lower guide plate 64, respectively. At that moment, the upper suction pad 34 and the lower suction pad 44 adsorbed to the upper and lower surfaces of the packaging bag B are released from adsorption [see FIG. 24 (al) and FIG. 24(b)]. The packaging bag B is supported by the upper guide plate 63, the lower guide plate 64, and the first and second clamps 56, 56, 57, and 57 of the bag clamp unit 5. When it is necessary to make the width of the upper surface of the bag B wider than the lower surface, the upper guide plate expansion cylinder 67 is activated, and the divided pieces of the upper guide plate 63 are expanded, so that the width of the upper surface is wider than that of the lower surface. It will be done.

After this, the upper suction unit 3 returns to the bag stock unit 2, and the lower suction unit 4 returns to its initial state.

Next, the drive motor 52 of the bag clamp unit 5 and the drive motor 65 of the guide unit 6 are activated, and the traveling truck 51, the main traveling truck 61, and the lower traveling truck 62 of the bag clamping unit 5 are operated simultaneously. Move toward bag covering position Y. As a result, the expanded packaging bag B is sent to the bag covering position Y and is placed over the end of the elongated body A [see FIGS. 25(a) and 25(b)]. At this time, the upper and lower surfaces of the packaging bag B are supported from the inside by the upper guide plate 63 and the lower guide plate 64, respectively, so that the periphery of the opening does not catch on the edge of the elongated body A.

After this, the main traveling truck 61 continues to travel, while the lower traveling truck 62
After stopping at the bag-covering position Y, the bag is pushed out from the traveling truck 51 toward the conveyor 1 by a lower traveling truck pushing cylinder 69 provided on the traveling truck 51. As a result, the upper guide plate 63 and the lower guide plate 64 are completely removed from the packaging bag B (see FIGS. 26(a) and 26(b)). With the above steps, the bag covering on the end of the elongated body A is completed. Thereafter, the main traveling truck 61 and the lower traveling truck 51 return to the vicinity of the manufacturing method open position X again, and the upper guide plate 63 and the lower guide plate 64 wait for the next bag B.

(a) and the same figure (see bl).

Then, the first and second clamps 56 and 57 that clamp one side edge of the packaging bag B open, releasing the negative side edge, and the drive motor 52 of the bag clamp unit 5 opens. and clamp lifting cylinders 53.53 operate together, and the first and second clamps 56, 56, 57.57
returns to its original position while descending. At the same time, the transport conveyor 1 is operated, and the elongated object A covered with the packaging bag B as described above is moved to the band binding position Z, and the next new elongated object A is moved to the bag covering position. At the same time, the drive motor 72 of the bag shifting unit 7 is activated, and the traveling cart 71 moves toward the band binding position Z at the same speed as the conveyor 1 [FIGS. 28(a) and 28(a)] figure(
b) see]. As a result, the side edge of the packaging bag B placed over the end of the elongated body A on the traveling direction side of the elongated body A is pulled in the traveling direction by the biasing clamp 7373. Pushed to the side.

In this way, while the elongated body A is being transported to the band binding position Y, the folding clamps 85, 85 of the folding unit 8 are kept open, and the biasing clamps 73.
It is waiting at the stop position of 73.

Eventually, when the end of the elongated body A reaches the band binding position Y and the biasing clamps 73.73 reach the stop position, the folding clamps 85.85 close and clamp one side edge of the packaging bag B. (See Figure 29).

Then, the offset clamps 73.73 open and release the clamping of the negative side edge, so that the negative side edge is clamped only by the folding clamps 85.85 [see Fig. 30 (al and same)]. See figure ('b)].

When the biasing clamps 73 and 73 release the clamping of the negative side edge, the biasing clamp lifting cylinder 74 and the biasing unit 7
The drive motor 72 of is activated again, and the offset clamp 73.7
3 returns to the initial position (near the bag covering position Y) by passing over the end of the elongated body A, and prepares for a new shift.

Next, the extrusion cylinder 94.9 of the folding auxiliary unit 9
4 is activated, the presser rods 91 and 91 move forward (in the direction of approaching each other), and the presser rod lifting cylinder 92
．． 92 is activated, and the presser rod 91.91 descends toward a position near the tip of the folding clamp 85.85. The presser rods 91 and 91 then come into contact with the upper surface of the excess portion E of the packaging bag B that is biased by the biasing unit 7 and generated on the traveling direction side of the elongated body A [Fig. (See figure price)].

Subsequently, the presser rod sliding cylinder 93.93 operates,
The presser rods 91, 91 move horizontally toward the end of the elongated body A [see FIG. 32 (al) and FIG. is pressed down by the presser rods 91 and 91, and the packaging bag B is brought into close contact with the inner side of its upper surface or the upper peripheral surface of the end of the elongated body A.

As described above, the presser rods 91.91 slide on the upper surface of the surplus portion E and reach the base of the surplus portion E [33rd
(see Figures (a) and (b))] and the folding unit 8
drive motor 82 and folding clamp lifting cylinder 83
The traveling trolley 81 moves in the opposite direction to the traveling direction of the elongated body A, and the arm rods 84, 8
4 moves upward. As a result, the folding clamps 85.85 turn upward around the end of the elongated body A while holding the tip of the surplus portion E (one side edge of the packaging bag B). . At this time, the moving speed of the traveling cart 81 and the arm rods 84, 84 is the same as that of the folding clamp 85.
85 is set at such a speed that it can always rotate around the end of the elongated body A without loosening the excess portion E (without continuing to pull it).In this way, the folding clamp 85 However, as the tip of the surplus portion E continues to be pulled and moves upward around the end of the elongated body A, the base of the surplus portion E is pressed against the peripheral surface of the end by the presser rods 91 and 91. Since the folding clamp 85.85 is attached, a force is gradually applied to the folding clamp 85.85 to pull the clamp 85.85 downward.Then, when the folding clamp 8-5.85 is rotated to the position, the above force is applied to the folding clamp 85.85. The force that keeps the clamp 85° 85 in a horizontal state is exceeded, and as a result, the folded clamp 85° 85 has its tip aligned with the presser rod 91.9.
34 (a) and the same figure (bl)].

As a result, the surplus portion E is neatly wrapped around the circumferential surface of the packaging bag B without loosening, and the tip of the surplus portion E is prevented from being damaged by the tip of the folding clamp 85°85.

Eventually, the tip of the folding clamp 85.85 comes into contact with the circumferential surface of the packaging bag B, and when the winding of the excess portion E is completed, the presser rod extrusion cylinder 94.94 of the folding auxiliary unit 9 is activated, and the presser The rods 91, 91 move away from each other and exit from the base of the surplus portion E [see FIGS. 35(a) and 35(bl)].

When the withdrawal operation of the presser rods 91, 91 is completed, the binding machine 10 is activated, the binding arm 101 is closed, and binding is started. At this time, make sure that the excess part E does not loosen.
The tip of the surplus portion E continues to be held by the folding clamps 85 and 85 until the binding is completed [3rd
See Figure 6(a) and Figure 6(b)]. When the binding is completed in this way, the folding clamps 85, 85 are opened to release the tip of the excess portion E, and the binding arm 101 of the binding machine 10 is opened, thereby wrapping the end of the elongated body A. Completed [See Figure 37 (a) and Figure 37 (b)]
Thereafter, the transport conveyor 1 is operated again to carry out the wrapped elongate body A from the band binding position Y.

FIGS. 16 and 18 show the wrapped state of the end of the elongated body A that has been wrapped as described above. In addition, FIG. 16 shows the case where the elongated body A is a bundle of tube materials P... so that the outer circumferential shape has a hexagonal shape as shown in FIG. 15, and FIG. A case is shown in which the length body A is a bundle of tube materials P... so that the outer circumferential shape has a substantially inverted trapezoidal shape as shown in FIG.
