Description

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 pouring the pipes into containers called pallets.

[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 pallet as described above,
Pallets have considerable depth due to the need to stock a large number of pipes. Therefore, in the early stage of the stock, the head when the pipe is inserted is large, and the sound when the pipe hits the bottom of the pallet or when the pipes collide with each other is large.

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 or the like, it is necessary to stack the pipes in parallel so that the pipes do not intersect. However, in the prior art, since the pipes are simply put on the pallet, the pipes inevitably cross each other. . Therefore, when storing in a warehouse, the pipes had to be manually rearranged again. Also, it has been difficult to monitor virtually everything and manually align them completely. Further, as described above, according to the prior art, the pipes cross each other in the pallet, so that when the pipe is in the pallet, a local force is applied to the pipe 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.

According to the first aspect of the present invention, there is provided a support frame on which long objects are stacked, and a bottom portion of the support frame on which the long objects are placed. A lifting device that descends to the side to open the long object, and a break-in member that contacts the long object in the support frame and moves in the rolling direction of the long object. Is loaded into a support frame, and the long objects are aligned by a running-in member.

The apparatus for stacking long objects according to the present invention is for stacking long objects in a support frame. The long objects are placed on the support frame and lowered to the bottom of the support frame to open the long objects. The long object is lowered to the bottom side of the support frame, and then the long object is opened. Therefore, the long object is thrown into the support frame after being transported to the bottom side. Therefore, according to the apparatus for stacking long objects of the present invention, the head at the time of charging is small. In addition, the apparatus for stacking long objects according to the present invention has a running-in member, and the long-running objects are aligned by the running-in member, so that the pipes can be stacked neatly without crossing the pipes.

According to a second aspect of the present invention, the lifting device has a table inclined toward the support frame, and a long object is dropped on the tip of the table. 2. A device for stacking long objects according to claim 1, wherein a stopper is provided to prevent the lifting of the object, and the stopper is opened when the elevating device descends to a predetermined position.

In the long object stacking device according to the present invention, the lifting device has a table inclined toward the support frame.
A stopper for preventing a long object from falling is provided at the tip of the table. Therefore, the long object is placed on the table without falling, and is carried to the bottom. The stopper is opened when the elevating device descends. Therefore, when the stopper is opened, the long object rolls along the inclination of the table and is thrown into the support frame side.

According to a third aspect of the present invention, the break-in member reciprocates in a direction substantially perpendicular to the long object and has a position parallel to the long object. 3. The device for stacking long objects according to claim 1, wherein the device can be retracted.

In the apparatus for stacking long objects according to the present invention, the conditioning member reciprocates in a direction substantially perpendicular to the long objects. Therefore, the long objects perform a rolling motion, and other long objects are fitted into gaps between the long objects and aligned. In the long object stacking device of the present invention, the break-in member can be retracted to a position parallel to the long object. Therefore, when extracting the long object from the long object stacking device of the present invention, the break-in member does not interfere. As one usage of the long object stacking apparatus of the present invention, a long object obtained by dividing the number of each layer laminated on the support frame into several times is placed on the elevating device. Therefore, when all the long objects are put into the support frame, the long objects are buried and aligned without any excess or shortage by the running-in member.

According to a fourth aspect of the present invention, in which the above-mentioned invention is further improved, a member which generates frictional force and has elasticity is provided on an abutting surface of the break-in member with a long object. The device for stacking long objects according to any one of claims 1 to 3, characterized in that:

Embodiments of the present invention will be described below. FIG. 1 is a perspective view of a main part of a long product stacking apparatus according to the present invention. FIG. 2 is a front view and a right side view of the elevating device of the long object stacking device in FIG. 1. FIG.
FIG. 2 is a front view, a right side view, and a plan view of a support frame of the long object stacking device in FIG. 1. 4 to 6 are explanatory diagrams for explaining the function of the long object stacking device in FIG.

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 device for stacking long objects according to the present embodiment is an example suitable for stacking relatively small-diameter pipes having an outer diameter of 28 mm or less, which are particularly soft and easily deformed into a bow shape and easily deformed.

The stacking device 1 for a long object according to the present embodiment comprises:
The lifting device 2, the support frame 3, and the break-in member 5
Composed of

First, the lifting device 2 will be described. The lifting device 2 has five standing members 6 as shown in FIG. 2 (only two members are shown in FIG. 1), and two lifting members 6 are provided on the inner and outer surfaces thereof. Tables 7, 8
Is provided. The standing body 6 is self-supporting in the vertical direction, and has two sets of chains and motors (not shown) arranged therein. And the outer lifting table 7
It is inclined downward from the outside toward the standing body 6. A flange 11 is provided at the outer end of the outer lifting table 7 so that the pipe 10 does not fall off. The outer lifting table 7 is attached to a part of the chain of the standing body 6 described above, and moves up and down along the outside of the standing body 6.

The inner lifting table 8 is inclined downward from the standing body 6 toward the support frame 3. A claw-shaped stopper 15 is provided at the tip of the inner lifting table 8. The stopper 15 is actuated by a cylinder or the like (not shown),
0 is stopped, and again, the pipe 10 is opened. The inner lifting table 8 is attached to a part of the chain of the standing body 6 like the inner lifting table 7 described above.
It goes up and down along the inside of the standing body 6. The inner lifting table 8 can be stopped at a plurality of positions.

As shown in FIG. 3, the support frame 3 comprises five standing frames 17 (only two are shown in FIG. 1) and the base frame 1
8 and a wall 19 for positioning. The base frame 18 supports the standing frame 17 and the positioning wall 19 and keeps them at a constant interval. The positioning wall 19 is provided upright at the end of the support frame 3, and the upper end is slightly open. The positioning wall 19 is used for positioning the pipe 10 in the longitudinal direction by abutting the end of the pipe 10.

The standing frames 17 have the same shape and structure. To explain one of them, the standing frame 17 is relatively narrow,
It has left and right side members 20 and 21 and a bottom member 22. In the present embodiment, the space created by the left and right side members 20 and 21 has a tapered shape that expands upward. The standing frame 17 has the bottom member 22 as described above, and has an inverted trapezoidal shape as a whole. The reason why the shape of the standing frame 17 is tapered is to secure a draft angle when the bundle of pipes 10 is extracted from the long product stacking device 1.

A receiving member 25 is provided on the bottom member 22 of the standing frame 17. The receiving member 25 is
It has a bar shape, and one end is swingably fixed to a side portion of the bottom member 22 by a pin 26. Therefore, the receiving member 25
Can swing about the pin 26. A bar 27 is connected to the tip of the receiving member 25, and a link mechanism 30 composed of two straight members 28 and 29 is formed on the other end of the bar 27. Further, a common shaft 31 is inserted through the other end of the link mechanism 30. That is, the common shaft 31 is
And the front ends of the link mechanisms 30 of the standing frames 17 are connected to each other. And the common shaft 31
Is connected to a motor or a torque actuator (not shown). Therefore, by rotating a torque actuator (not shown) or the like, the common shaft 31 rotates, and the link mechanism 30 becomes linear or “C” -shaped, and the open side of the receiving member 25 is raised and lowered. Therefore, the receiving member 25 of each standing frame 17 moves out of the bottom of the support frame 3 by rotating a torque actuator or the like (not shown).

The running-in member 5 is provided with a running-in bar 33 that can move in the vertical direction and the turning direction, and that reciprocates linearly. That is, the break-in member 5 has the lift 34 that is raised and lowered by the cylinder 35 that stands upright. The elevating table 34 has a fixed side member 36 and a movable side member 37, and both are connected by a hinge (not shown). The fixed side member 36 is connected to the rod of the upright cylinder 35 described above. In addition, fixed side member 3
A small cylinder 38 is fixed to 6, and the rod of the small cylinder 38 is joined to the movable member 37. Therefore, when the rod of the cylinder 38 is extended,
When the movable member 37 is parallel to the bottom member 22 of the standing frame 17 as indicated by the solid line in FIG.
The movable side member 37 rotates 90 ° as indicated by the two-dot chain line. That is, when the rod of the cylinder 38 is extended when the pipes 10 are stacked as described later, the movable side member 37
When the rod is extended, it becomes a positional relationship in which it is retracted to a position parallel to the pipe 10.

The movable side member 37 is provided with a break-in bar 3.
A cylinder 32 for reciprocating the cylinder 3 is fixed. On the other hand, the break-in bar 33 is fixed to the lower surface of the movable member 37 so as to be capable of linear movement. The rod of the reciprocating cylinder 32 straddles the distal end of the movable member 37 and is connected to the break-in bar 33. Therefore, when the rod of the reciprocating cylinder 32 is expanded and contracted,
Moves linearly along the movable side member 37. The lower surface of the break-in bar 33 is made of a material such as rubber or urethane resin which is rich in elasticity and easily generates friction.
In addition, the lower surface of the break-in bar 33 is formed with an uneven shape so as to easily generate friction.

The positional relationship between the lifting device 2 and the support frame 3 and the running-in member 5 will be described. As shown in FIG. 1, the lifting device 2 is provided on the side of the supporting frame 3 and the running-in member 5 is provided. The support frame 3 is fixed to a dedicated frame 14 (see FIG. 1) provided on the opposite side of the lifting / lowering device 2.

Next, the operation of the long object stacking apparatus 1 according to the present embodiment will be described with reference to FIGS. As a preparation for stacking the pipes 1, the rod of the cylinder 38 of the break-in member 5 is contracted and placed in a retracted position as shown by a two-dot chain line in FIG. The pipe 10 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 10 is placed on the lifting table 7 outside the lifting device 2 of the present embodiment as shown in FIG. The pipes 10 may be placed one by one on the outer lifting table 7, or a plurality of pipes may be placed at one time.

When the pipe 10 is placed on the outer lifting table 7, the lifting table 7 moves up along the standing body 6. Here, the lifting table 7 is inclined downward from the outside toward the standing body 6 as described above, but since the standing body 6 is on the inclined side, the pipe 10 does not fall down.

When the elevating table 7 reaches the top of the standing body 6, the obstacles of the pipe 10 are eliminated and the pipe 10
Rolls along the inclination of the elevating table 7 and is placed on the inner elevating table 8. The inner elevating table 8 is inclined downward from the standing body 6 toward the support frame 3, but the stopper 15 is provided at the tip of the inner elevating table 8. Rolling is prevented. In this way, a part of the pipes 10 constituting the first layer is first placed on the inner lifting table 8 (4a). Also, before the elevating table 8 descends, the common shaft 31 is rotated, and the receiving member 25 is lifted out of the bottom member 22 of the support frame 3 in advance.

Then, in this state, as shown in FIG. 4B, the inner lifting table 8 is lowered to a position near the bottom. Here, as described above, before the elevating table 8 descends, the common shaft 31 is rotated, and as shown in FIG.
Since the pipe 5 has been lifted out of the bottom member 22 of the support frame 3 in advance, the pipe 10 placed on the lifting table 8 is picked up by the receiving member 25 from below. Then, the receiving member 25 is lowered and sunk into the bottom member 22 of the support frame 3, and the pipe 10 on the receiving member 25 is placed on the bottom member 22 of the support frame 3. In this way, a part of the first layer of the pipe 10 (three out of five in the figure) is placed on the bottom member 22 of the support frame 3.

The pipe 10 of the first layer is placed on the elevating table 8 inside, and is picked up from below by the receiving member 25 and placed on the bottom member 22 of the support frame 3.
They are arranged in an aligned state as in (d). Further, since the pipe 10 of the first layer is picked up from below by the receiving member 25 and placed on the bottom member 22, there is no impact noise as in the prior art, and the pipe 10 is not damaged.

The empty lifting table 8 is shown in FIG.
Ascend to the top. Then, the remaining pipes 10 of the first layer are newly placed from the outer lifting table 7 to the inner lifting table 8. Here, the number of pipes 10 placed on the elevating table 8 is made to match the remaining number of pipes 10 constituting the first layer. In the example of FIG. 5, two pipes 10 are placed on the lifting table 8. Subsequently, as shown in FIG. 5E, the inner lifting table 8 is lowered to the bottom side. Specifically, the lifting table 8 is lowered to a position immediately adjacent to the existing first-layer pipe 10. And the stopper 15 at the tip
Defeat As a result, as shown in FIG. 5 (f), when the pipe 10 enters the support frame 3,
For example, the pipes 10 to be newly inserted collide with each other, or the pipes 10 to be newly inserted collide with each other as shown in FIG. In the stacking apparatus 1 for long objects according to the present embodiment, the pipes 10 which are in an irregularly overlapping or intersecting stacked state as shown in FIG.
Are arranged in parallel by the conditioning member 5.

That is, the break-in member 5 is in a state shown by a two-dot chain line in FIG. 1 (a state in which it is retracted in parallel with the pipe 10).
Then, it is swung 90 °, and the break-in bar 33 is moved to a position orthogonal to the pipe 10. Then, the elevator 34 is moved to an appropriate position, and the break-in bar 33 is brought into contact with the pipe 10. And repeatedly extend and retract the rod of the cylinder 32,
The running-in bar 33 is reciprocated. The contact portion of the break-in bar 33 with the pipe 10 is provided with rubber or the like that is rich in frictional force and elasticity, and the contact portion is provided with irregularities. Rolls with the reciprocating motion of. Therefore, the pipe 10 fits into the gap of the first-layer pipe 10 and is aligned.

When the alignment of the pipes 10 is completed, the break-in bar 33 is moved upward. Then, a new pipe 10 is placed on the inner lifting table 8 (FIG. 6h). After that, the above steps are repeated, and the inner lifting table 8 is lowered to the vicinity of the existing first layer pipe 10,
The stopper 15 is removed, the pipe 10 is opened, the break-in bar 33 is lowered to make contact with the pipe 10, and the pipe 10 is rolled by linear motion to align the pipe 10. In addition,
Depending on the diameter of the pipe, such a break-in operation may not be necessary for the second and subsequent layers. Thus, the pipes 10 are stacked in a predetermined number of stages, and the operation is completed.

Then, the bundle of pipes 10 is removed from the stacking device 1 for long objects by the transfer device, and transferred to a warehouse or an intermediate stocking place. Means for transporting the bundle of pipes 10 from the long product stacking apparatus 1 of the present invention is arbitrary. For example, a claw of a forklift is inserted between the upright frames 17 and the claw is raised to move the pipe from the upright frame 17 to the pipe. It is conceivable to scoop 10 bundles. It is also conceivable to use a dedicated transport device.

The above description has been made on the assumption that the apparatus for stacking long objects according to the present invention is used for temporary stock immediately after the pipe 10 is manufactured. It is not limited to use. 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. Note that, in the long object stacking device 1 of the present embodiment, the upright frame 17 forms a taper that expands upward, and the pipes 10 are stacked more in the upper layer. In the case where the long object stacking device 1 of the embodiment is used for preliminary stacking work when stacking the pipes 10 or the like on a truck, it is desirable that the bundle of the pipes 10 be turned upside down before stacking on the truck.

[0035]

According to the long object stacking apparatus of the present invention, a long object such as a pipe hits the support frame with a small head. Therefore, in the long object stacking device of the present invention, noise is not generated when a pipe or the like is inserted, and the device is quiet. In the long object stacking device of the present invention, the long objects are aligned by the break-in member, so that the long objects are stacked neatly without intersecting each other.

In the apparatus for stacking long objects according to the second aspect of the present invention, a structure is employed in which the long objects are put into the support frame by utilizing the inclination, so that the long objects move smoothly.

Further, in the apparatus for stacking long objects according to the third aspect, the long objects roll by the break-in member, and other long objects are fitted into the gaps between the long objects and aligned. You. For this reason, the long objects are smoothly aligned and rarely cross each other. Further, in the long object stacking device of the present invention, the break-in member can be retracted to a position in a direction parallel to the long object, so that the break-in member does not hinder the extraction of the long object. .
