DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for stacking long objects such as pipes and round bars in parallel and in multiple rows.

[0002]

2. Description of the Related Art A resin pipe is continuously formed by an extruder and cut into a predetermined length to be manufactured. Then, the pipes are temporarily stocked until a predetermined number is accumulated before being stored in a warehouse or the like. In the prior art, temporary stocking of pipes has been performed by charging the pipes into containers called stanchions.

[0003]

The prior art method of temporarily stocking pipes is a commonly used method, but has a problem in that it is noisy and it is difficult to align the pipes. . That is, the prior art method simply puts the pipe into the stanchion as described above, but the stanchion has a considerable depth due to the need to stock a large number of pipes. Therefore, in the early stage of the stock, the drop when the pipe is inserted is large, and the sound when the pipe hits the bottom of the stanchion or when the pipes collide with each other is loud.

In the prior art, the impact at the time of collision is large, and the pipe may be deformed. Furthermore, when storing in a warehouse etc., it is necessary to pile up in parallel so that the pipes do not intersect, but in the prior art, since the pipes are simply thrown into the stanchion, the pipes will inevitably intersect . Therefore, when storing in a warehouse, the pipes had to be manually rearranged again. Further, as described above, according to the related art, since the pipes cross each other in the stanchion, a local force is applied to the pipe while in the stanchion, and the pipe may be deformed.

Accordingly, the present invention focuses on the above-mentioned problems of the prior art, and it is possible to quietly temporarily stock long objects such as pipes and to automatically arrange and stack long objects. The task is to develop a stacking device.

In the drawings, reference numeral 1 denotes an apparatus for stacking long objects according to an embodiment of the present invention. The device for stacking long objects according to the present embodiment is specifically used for temporarily stocking a pipe made of vinyl chloride. The apparatus for stacking long objects according to the present embodiment is a suitable example particularly when stacking pipes having an outer diameter exceeding about 28 mm.

The stacking device 1 for a long object according to the present embodiment comprises:
It is roughly composed of a charging device 2 and a main device 3. The main body device 3 further includes a frame 10, a drum 11, and a sling 12.

First, the charging device 2 will be described. The charging device 2 is mounted on an upright body 20 as shown in FIGS.
Is provided. The standing body 20 is vertically independent, and has a chain and a motor (not shown) disposed therein. The elevating table 21 is for mounting the pipes 13 and has flanges at both ends so that the pipes 13 do not fall off (shown only in FIG. 1). The elevating table 21 is attached to a part of the chain of the upright body 20 and moves up and down along the upright body 20. The elevating table 21 is inverted when it reaches the top.

The main unit 3 includes the frame 1 as described above.
0, a drum 11 and a sling 12. The frame 10 is made of die steel or the like, and includes a lower base frame 30 and four standing frames 31, 32, 33, and 34. The base frame 30 includes the upright frames 31, 32, 33, 3
4 to keep them at a constant interval. The base frame 30 is shown only in FIGS. 1 and 2 and is not shown in other drawings.

The standing frames 31, 32, 33, 34
Since both have the same shape and structure, the standing frame 32 at the intermediate portion will be described as a representative. The standing frame 32 is relatively narrow in width, and has left and right side members 27 and 28 and a bottom member 29. In this embodiment, the space formed by the left and right side members 27 and 28 has a tapered shape that expands upward. The standing frame 32 has the bottom member 29 as described above, and has an inverted trapezoidal shape as a whole. The reason why the shape of the standing frame 32 is tapered is to secure a draft angle when the bundle of pipes 13 is extracted from the long stacking device 1. In other words, in the long object stacking device 1 of the present embodiment, the pipe 13 is ultimately supported by the upright frame 32, but the upright frame 32 abuts the pipe 13 discontinuously. The contact portion flexes and swells outward. Therefore, when the side members 27 and 28 of the standing frame 32 are made vertical, a large force is exerted when the bundle of pipes 13 is pulled out, which not only increases the size of the device but also causes damage to the pipe 13 when the bundle is pulled out. Becomes Further, in the present embodiment, the side members 27 and 28 and the bottom member 29 of the standing frame 32 are provided with grooves 38 (FIG. 4) inside.

The left and right side members 27, 2 of the standing frame 32
The rolls 35 and 36 are provided on the top of 8. In the present embodiment, the rolls 35 and 36 function as support portions. The drum 11 is provided on the loading device 2 side of the left and right lower portions of the side members 27 and 28 of the standing frame 32, and the roll 37 is provided on the other.

The sling 12 functions as a support, and is a long belt which has high tension and is easily deformed. The width of the sling (support) 12 is such that it fits within the groove 38 of the standing frame 32 described above.

The sling 12 is wound around the drum 11 with both ends overlapping as shown in FIG. Standing frame 3
Each of the drums 11 provided at 1, 32, 33 and 34 has
2 and 3, a common rotating shaft 41 is inserted, and the rotating shaft 41 receives power transmission from a motor 40 (shown in FIGS. 1, 2, and 3). Therefore, each drum 11 is synchronously rotated in the forward and reverse directions by a single motor 40.

When the drum 11 rotates in one direction, a sling 12 corresponding to the amount of rotation is drawn out from the drum 11, and when the drum 11 rotates in the opposite direction, the drum 11 rotates.
The sling 12 is rolled up. The intermediate portion of the sling 12 is suspended on rolls 35, 36, 37. Here, the rolls 35 and 36 are located at the same height and have a distance between them, and a middle part between them is a space. Therefore, the rolls 35, 3 of the sling 12
An intermediate portion of the portion supported by the supporting portion 6 is bent in a parabolic shape by gravity and becomes a valley shape. In addition, the span length of the sling (support) 12 between the rolls (supports) 35 and 36 is increased or decreased according to the rotation amount of the drum 11.

As will be described later, the pipes 13 are stacked in the valleys formed by the slings 12, and a sensor (not shown) is provided in a part of the main body device 3, and the sensors stack the pipes 13 at a maximum. The height is monitored, and the drum 11 is rotated so that the sling is extended so that the maximum piled-up height of the pipes 13 is constant.

The above-mentioned standing body 20 is juxtaposed beside the main unit 3 as shown in FIGS. 1 and 4, and a handover plate 39 is provided between the top of the standing body 20 and the upper part of the main unit 3. I have. The transfer plate 39 is provided with a slope descending toward the main device 3.

Next, an apparatus 1 for stacking long objects according to the embodiment
The operation of will be described. In the initial stage, the elevating table 21 is located at an intermediate portion of the standing body 20. In addition, the amount of the sling 12 extended is small, and the roll (support portion) 3
The span length of the sling 12 between 5, 36 is short. Therefore, the valley formed by the sling 12 is small as shown in FIGS.

The pipe 13 is continuously formed by an extruder (not shown), cut into a predetermined length by a cutting device (not shown), and conveyed by a conveyor or the like. Then, the pipe 13 is placed on the elevating table 21 of the charging device 2 of the present embodiment. The lifting table 21 may be provided with the pipes 13 one by one or a plurality of pipes at one time.

When the pipe 13 is placed on the elevating table 21, the elevating table 21 moves up along the standing body 20. Then, the lifting table 21 is inverted at the top, and the pipe 1
Discharge 3. As a result, the pipe 13 rolls on the slope of the transfer plate 39 and is inserted between the rolls 35 and 36 serving as support portions. The pipe 13 rolls down along the sling 12 and stops at the center of the valley formed by the sling 12 as shown in FIG. As described above, in the initial stage of loading, the amount of feeding of the sling 12 is small, and the length of the sling (support) 12 between the rolls (support portions) 35 and 36 is short. At this stage, the valley formed by the sling 12 is shallow.
Therefore, the impact when the pipe 13 falls is small. Further, as described above, since the pipe 13 rolls down along the sling 12, the impact at the time of falling is further reduced. Therefore, according to the apparatus for stacking long objects according to the present embodiment, there is no noise which is a problem in the related art. Also, there is no problem that the pipe is damaged as in the prior art.

When the loading of the pipe 13 is completed, the lifting table 21 returns to its original position. Then, another pipe 13 is placed again, and the rolls 35 and 3 serving as support portions are attached to the pipe 13.
Insert between 6. The second pipe 13 ′ rolls down along the sling 12 in the same manner as the previous pipe 13, and FIG.
As shown in (b), the operation stops alongside the pipe 13. The same applies to the third pipe 13 ″, which rolls down along the sling 12 and stops alongside the previous pipe 13 ′ as shown in FIG. 7B. Thus, the first rows of pipes 13 are arranged in parallel.

The pipe 13 to be further charged is shown in FIG.
As shown in (c), the pipes 13, 13 ', 1
Riding on 3 '', the second stage is formed.

When the second stage is piled up and the valley formed by the sling 12 becomes shallow, a sensor (not shown) responds and activates the motor of the drum 11 to rotate the drum 11 in the feeding direction of the sling 12. Then drum 1
1, the sling 12 is fed out twice, one is fed out through a roll 35, and the other is fed out through a roll 36, and the length of the sling (support) 12 between the rolls (supporting portions) 35, 36. Is increased. Here, in the long product stacking apparatus 1 of the present embodiment, since the length of the sling 12 fed from one roll 35 and the length of the sling 12 fed through the other roll 36 are the same, two stages are provided. The piled pipes 13 are lowered vertically straight. Therefore, pipes 13 stacked in parallel
Moves in the vertical direction while maintaining the parallel state. Then, a space is formed on the second stage pipe 13 as shown in FIG.

The pipe 13 is further fed into the main body device 3 by the feeding device 2, but every time the sensor responds, the motor of the drum 11 is started, the sling 12 is fed out little by little, and the pipe 13 falls. The head is always kept constant. Therefore, as shown in FIG. 8E, the pipes 13 are stacked in an orderly manner.

In this way, the pipes 13 are stacked, the sling 12 is fed out, and the length of the sling 12 to be delivered increases, and when the sling 12 reaches the bottom member 29,
As shown in FIG. 8 (f), the sling 12 has a groove 38 in the bottom member 29.
Get in. The same applies to the side members 27 and 28, and the sling 12 enters the groove 38 of the side members 27 and 28. Therefore, the pipe 13 is delivered from the sling 12 to the upright frames 31, 32, 33, and 34, and the pipe 13
Shifts from a state supported by the sling 12 to a state fixedly supported by the standing frames 31, 32, 33, and 34. Therefore, finally pipe 1
3 are stacked in parallel between the frames 10 as shown in FIG.

Then, the bundle of pipes 13 is removed from the stacking device 1 for long objects by the transfer device, and transferred to a warehouse or an intermediate stocking place.

In the above-described apparatus for stacking long objects according to the present invention, a sling is used for the support. In the present embodiment, the sling is used as the structure of the support because the pipe 13
The reason for this is that the support is not limited to a sling, because it is difficult to scratch the drum and it is easy to double-wrap the drum. That is, the support needs only to be a long object that can be easily deformed, and a wire rope, a fiber rope, a chain, or the like can also be used. Further, a sheet-like member is also included in the “support formed of a long object that can be easily deformed” as a constituent member of the present invention. When a wide member such as a sheet is used for the support, the pipe 13 may not need to be held by a plurality of supports as in this embodiment.

Although the above description has been made on the assumption that the long object stacking device of the present invention is used for temporary stock immediately after the pipe 13 is manufactured, the long object stacking device of the present invention is not limited to the above. It is not limited to this application. As another application of the stacking device for long objects of the present invention, for example, it is conceivable to use it for preliminary stacking work when stacking pipes or round bars on trucks or packing. In addition, the stacking apparatus 1 of the long object of this embodiment.
In this case, the standing frame 32 has a taper that expands upward, and the pipes 13 are piled up more as they go up. When used for a preliminary stacking operation when loading 13 or the like on a truck, it is desirable to turn the bundle of pipes 13 upside down before loading on a truck.

The means for transporting the bundle of pipes 13 from the long material stacking apparatus 1 of the present invention is optional. For example, a claw of a forklift is inserted between the standing frames 31, 32, 33, and 34, and the claw is inserted. Lift the pipe 10 from the frame 10
It is conceivable to scoop up the bundle of 3. It is also conceivable to use a dedicated transport device.

Hereinafter, a transfer device which is desirably used in combination with the long object stacking device of the present invention will be described.

The transfer apparatus 50 employed in this embodiment has a form of an overhead traveling crane as shown in FIGS. 9 and 10, and has a rotating claw provided at the club 53 (FIG. 10).
That is, the transport device 50 includes a fixed rail 51 attached to the ceiling and a movable girder 5 moving along the fixed rail 51.
Have two. A club 53 that moves along the moving girder 52 is attached to the moving girder 52. The structure of the fixed rail 51 and the moving girder 52 and the traveling structure of the club 53 are the same as those of a known overhead traveling crane. It is desirable that Four wires 54 are provided from the club 53, and the transport device main body 55 is suspended by the four wires 54.

The transporting device main body 55 includes a frame-like frame 56.
And six turning pawls 60 and 70 are provided.
The turning claws 60 and 70 have two types, a pin structure and a receiving structure, and function as a pair. In other words, the transport device 50 of the present embodiment has three pairs of turning claws. As shown in FIGS. 11 and 12, the revolving claw 60 having the pin structure includes a hanging portion 62 hanging down from the flange portion 61 and a horizontal portion 63 bent at a right angle from the lower end of the hanging portion 62. The hanging portion 62 has four surfaces, and one of the two opposing surfaces is parallel and the other is an inclined surface 65. More specifically, the same surface as the projecting direction of the horizontal portion 63 is an inclined surface 65 that is obliquely inclined. A pin 67 is provided at the tip of the horizontal portion 63 in the vertical direction. The pin 67 is supported in a vertical position by a fork 66 extending vertically in parallel as shown in FIGS. A ring-shaped follower 68 is attached to an intermediate portion of the pin 67.

On the other hand, the turning claw 70 of the receiving structure is different from the above-mentioned turning claw 60 of the pin structure only in the structure of the tip portion. That is, the turning claw 70 of the receiving structure also has the hanging part 62 and the horizontal part 63, and one surface of the hanging part 62 is the inclined surface 65. And in the turning claw 70 of the receiving structure,
A concave notch 71 is provided at the tip of the horizontal portion 63. The notch opening direction is a direction corresponding to the side surface with respect to the protruding direction of the horizontal portion 63. See Figure 1 for details of the site.

The revolving pawls 60 and 70 are capable of revolving 90 degrees. That is, the turning claws 60 and 70 turn in a state where the horizontal portions 63 are linear as shown in FIG. 12 because the horizontal portions 63 are parallel to each other as shown in FIG. When the horizontal portions 63 are linear as shown in FIG. 12, the inclined surfaces 65 of the revolving claws 60 and 70 have a tapered shape. The tapered shape widens as going upward, and has an inverted trapezoidal shape. The shape when the horizontal portions 63 are linear is equal to the shape of the upright frame 32 of the above-described long material stacking device 1. When the horizontal portions 63 are linear, the pin 67 belonging to the pivoting claw 60 having the pin structure and the notch 71 belonging to the pivoting claw 70 having the receiving structure are fitted.

Next, a procedure for transporting a bundle of pipes 13 stocked in the long product stacking apparatus 1 of this embodiment using the transport device 50 will be described. When transporting the bundle of pipes 13 stocked in the long object stacking device 1 of the present embodiment using the transport device 50, first, the moving girder 52 and the club 53 are moved, and as shown in FIG.

Is located between the standing frames 31, 32, 33, 34. The pipe 13 is supported by the standing frames 31, 32, 33, 34 of the device 1 for stacking long objects, and the standing frames 31, 32,
Since parts other than the contact parts with 33 and 34 are bent by their own weight, it is desirable that the revolving pawls 60 and 70 be placed in the vicinity of the standing frames 31, 32, 33 and 34 with little bending.

From this state, the turning claws 60 and 70 are
After turning by 0 °, each pair of turning claws 60 and 70 is brought into a state in which the horizontal portions 63 are linear as described with reference to FIG. As a result, as shown in FIG. 16, the horizontal portions 63 of the revolving pawls 60 and 70 go under the bundle of the pipes 13, and the pins 67 at the ends and the cutouts 71 fit under the bundle of the pipes 13. Therefore, the bottom surface and the left and right sides of the bundle of pipes 13 are surrounded by the six revolving claws 60, 70, and the bundle of pipes 13 is placed in a shape like a palanquin or box jig. Further, as described above, the tapered shape formed by the inclined surfaces 65 of the revolving pawls 60 and 70 is equal to the tapered shape of the standing frame 32 of the long stacking device 1, so that the relative positional relationship of the pipes 13 is determined. Without changing, the revolving pawls 60, 70
Holds a bundle of pipes 13.

Then, the transport device main body 55 is lifted. Here, in the long object stacking device 1 of the present embodiment, since the standing frame 32 has a tapered shape that expands upward, there is an appropriate draft angle, and the long object stacking device 1
The load when pulling out the bundle of pipes 13 from is small. For the same reason, the pipe 13 is not damaged when the bundle of the pipes 13 is pulled out. Pipe 1
After the bundle 3 is lifted, the moving girder 52 and the club 53 are moved to transport the bundle of pipes 13 to a desired position.

Although the transport destination is arbitrary, for example, FIG.
It is convenient to use a pipe stock device 80 as shown in FIG. The pipe stocking device 80 has a stock space 81 having the same shape as the standing frame 32 of the long stacking device 1. 17 and 18, a vertical wall 82 is provided at one end of the stock space 81. The bundle of pipes 13 transported by the transporting device main body 55 is transported to the stock space 81 of the pipe stocking device 80, and the turning claws 60 and 70 are moved in the opposite direction to the above-described process.
From the state in which the horizontal portions 63 are linear as described in the above, the horizontal portions 63 are returned to a state in which the horizontal portions 63 are parallel as shown in FIG. 11, and the bundle of pipes 13 is opened.
