  Conventionally, when a single pipe is returned, the single pipe is manually stored in the storage rack and returned. However, the single pipe is relatively long and has a certain weight, which makes the operation complicated. Moreover, when storing in a storage rack, it is desirable to store a single pipe neatly arranged. If the single tubes cross in the storage rack and are stored randomly, the storage efficiency is poor and the number of single tubes cannot be checked in the storage rack. You will have to check the number of tubes. However, if the single pipes are neatly arranged and stored, the storing operation becomes worse.

  Accordingly, it is an object of the present invention to provide a single tube processing apparatus that can reduce the burden on humans and more easily handle a single tube.

The pieces are arranged so as to produce an intersecting state and a non-intersecting state that intersect with each other depending on the rotational position. Monotube processing apparatus characterized by there is provided.

  According to this single pipe processing apparatus, when the single pipe is inserted into the single pipe inlet, the direction of the single pipe is aligned by the restriction piece, and the single pipe passes through the restriction piece by its own weight and falls. Therefore, it is not necessary to align the direction of the single tube manually, reducing the burden on humans and handling the single tube more easily.

  In the present invention, the temporary pipe is disposed below the restriction piece, the temporary pipe passing through the restriction piece is temporarily placed, and the single pipe is disposed below the temporary placement part. It is possible to adopt a configuration comprising an attaching means for attaching the tag to the attachment means and a transfer robot for transferring the single tube temporarily placed on the temporary placement portion to the attachment means. According to this configuration, a tag for identifying this can be automatically attached to the single tube.

<First Embodiment>
FIG. 1 is an external perspective view of a single tube processing apparatus 1 according to an embodiment of the present invention, and FIG. 2A is a cross-sectional view taken along line II in FIG. In FIG. 1, arrows X and Y indicate the horizontal direction (orthogonal to each other), and arrow Z indicates the vertical direction (the vertical direction) (hereinafter the same in each figure). The single pipe processing apparatus 1 is an apparatus for processing a single pipe having a circular cross section, and includes a housing having a hollow, substantially rectangular parallelepiped shape by side plates 11 to 14, a bottom plate 15, and top plates 16 and 17.

  The side plates 11 and 12 are spaced apart from each other in the X direction and arranged to face each other. The side plates 13 and 14 are spaced apart from each other in the Y direction and arranged to face each other. The top plates 16 and 17 are disposed at both ends of the upper surfaces of the side plates 11 and 12 so as to be separated from each other in the Y direction. An opening formed by the top plates 16 and 17 and the upper portions of the side plates 11 and 12 constitutes a single tube inlet 18. The single pipe inlet 18 is opened on a substantially horizontal plane and has a substantially rectangular shape.

  Below the side plate 13, an opening 19 for taking the storage rack 2 into and out of the single pipe processing apparatus 1 is formed. The storage rack 2 has a hollow, substantially rectangular parallelepiped shape with an open upper surface, and includes a bottom plate 2a and first and second side plates 2b, 2c that extend upward from the bottom plate 2a and face each other. The storage rack 2 is disposed in the lower part of the single pipe processing apparatus 1, and stores a single pipe that passes through restriction pieces 20a and 21a described later and falls.

  Restricting members 20 and 21 are provided at the single pipe inlet 18. The side plate 11 is provided with a drive mechanism 30 that rotates the regulating members 20 and 21. FIG. 2B is a perspective view showing a part of the regulating members 20 and 21 and the drive mechanism 30. Hereinafter, the configuration of the regulating members 20 and 21 and the drive mechanism 30 will be described with reference to FIGS. 1 and 2B. Each restricting member 20, 21 is provided with a plurality of restricting pieces 20 a, 21 b that restrict the passage of a single tube at the single tube inlet 18.

  The restricting pieces 20a extend from the one side 18a side of the single pipe inlet 18 toward the central portion 18c of the single pipe inlet 18 (in the + Y direction), and are arranged at intervals in the direction along the one side 18a (X direction). ing. On the other hand, the restricting piece 20b extends from the other side 18b facing the one side 18a of the single pipe inlet 18 toward the central portion 18c (in the −Y direction), and is spaced in the direction along the other side 18a (X direction). Are arranged.

  Each regulating member 20, 21 includes shafts 20b, 21b on the lower surface side. The shafts 20b and 21b extend in the X direction, protrude from both ends of the restricting members 20 and 21 in the X direction, and are supported by the side plates 11 and 12, respectively. Accordingly, the restricting members 20 and 21 are rotatable around the shafts 20b and 21b, respectively. Therefore, the restricting pieces 20a and 21a are rotatable around the shafts 20b and 21b, respectively. Each regulating member 20, 21 is provided with shafts 20 c, 21 c protruding from the end surface in the −X direction on the end surface in the −X direction. The shafts 20c and 21c pass through elongated holes 11a and 11b formed in the side plate 11, respectively, and project outside the housing.

  The drive mechanism 30 includes a motor 31 supported on the side plate 11 via a bracket. A pinion gear 32 is fixed to the output shaft of the motor 31, and the pinion gear 32 meshes with a flat gear 33 that is rotatably supported by the side plate 11. Flat gears 34 and 35 are rotatably supported on the side plate 11 at both sides in the Y direction of the flat gear 33, respectively. These flat gears 34 and 35 are engaged with the flat gear 33, respectively. One ends of links 36 and 37 are pivotally supported on the side surfaces of the flat gears 34 and 35, respectively. The other ends of the links 36 and 37 are pivotally supported on the shafts 20c and 21c, respectively.

  Thus, when the motor 31 is rotated, the rotational force is transmitted to the respective flat gears 34 and 35 via the pinion gear 32 and the flat gear 33, and the rotational force is urged thereto. When the spur gears 34 and 35 rotate, the links 36 and 37 move to urge the shafts 20c and 21c to move in the vertical direction, whereby the restricting members 20 and 21 reciprocate around the shafts 20b and 21b. To do. As a result, the restricting pieces 20a and 21a of the restricting members 20 and 21 continuously reciprocate in the vertical direction around the shafts 20b and 21b, respectively. In the present embodiment, the regulating members 20 and 21 are reciprocally rotated continuously at a predetermined period with a phase shift.

  The restricting pieces 20a and 21a are arranged so as to generate an intersecting state and a non-intersecting state that intersect with each other depending on the rotation position. The non-intersecting state further includes a state where the single pipe can pass through the gap between the restricting pieces 20a and 21a and a state where the single piece cannot pass. In the present embodiment, as shown in FIG. 1 and FIG. 2B, the regulating pieces 20 a and 21 a are alternately arranged every other piece. Of course, the restriction pieces 20a and 21a may be alternately arranged in a plurality.

  Next, the operation of the single pipe processing apparatus 1 will be described with reference to FIG. FIG. 3A shows a mode in which a single pipe is put into the single pipe inlet 18. In the embodiment of FIG. 3 (a), the single pipe is inserted with its longitudinal direction greatly deviating from the X direction. Further, the restriction pieces 20a and 21a are in the non-intersecting rotation position, and the single pipe can pass through the gap between the restriction pieces 20a and 21a, but the single pipe has a longer longitudinal direction than the X direction. Since it has shifted | deviated and is mounted ranging over these on the control members 20 and 21, a single pipe cannot pass the clearance gap between the control pieces 20a and 21a. As the restricting members 20 and 21 rotate, the restricting pieces 20a and 21a reach the intersecting rotation positions as shown in FIG. As the regulating members 20 and 21 are rotated and inclined, the single tube changes its posture so that its longitudinal direction gradually faces the X direction.

  With the rotation of the regulating members 20 and 21, in the embodiment shown in FIG. 3C, the longitudinal direction of the single tube is substantially in the X direction, and the regulating pieces 20a and 21a are again in the non-intersecting rotation position. It is in. Although the single pipe can pass through the gap between the regulating pieces 20a and 21a, the single pipe rides on the regulating piece 20a and does not pass through the gap between the regulating pieces 20a and 21a at this timing. In the aspect of FIG. 3D with the rotation of the regulating members 20 and 21, the single pipe has dropped from the regulating piece 20 a, but the gap between the regulating pieces 20 a and 21 a cannot pass through the single pipe (the gap is small). Therefore, the single pipe has moved to the regulating member 21 side. Since the tip of the restriction piece 20a is in contact with the single tube, even if the single tube is directed obliquely at this timing, the single tube has its longitudinal direction substantially in the X direction.

  With the rotation of the regulating members 20 and 21, the regulating pieces 20a and 21a are in the pivoting position where the crossing state shifts to the non-crossing state in the aspect of FIG. The single pipe has dropped from the regulating piece 21a, but the gap between the regulating pieces 20a and 21a cannot pass through the single pipe (the gap is small), so the single pipe moves to the regulating member 20 side. ing. In accordance with the rotation of the regulating members 20 and 21, the regulating pieces 20a and 21a are in a non-intersecting state and the single pipe can pass through the gap between the regulating pieces 20a and 21a in the mode of FIG. Therefore, the single pipe passes through the regulation pieces 20 a and 21 a and falls to the storage rack 2.

  As described above, according to the single pipe processing apparatus 1, when a single pipe is inserted into the single pipe inlet 18, the direction of the single pipe is aligned in the X direction by the restriction pieces 20a and 21a, and the single pipe is restricted by its own weight. Pass through and fall. Therefore, it is not necessary to align the direction of the single tube manually, reducing the burden on humans and handling the single tube more easily. Note that FIG. 3 shows an example in which one single pipe is introduced for convenience of explanation, but a large number of single pipes can be introduced at the same time. For example, a plurality of single pipes may be introduced by a heavy machine or the like. Therefore, the working time can be further reduced.

  Next, a manner of storing a single tube in the storage rack 2 will be described. The storage rack 2 can store a plurality of single tubes arranged in the vertical direction (Z direction) with a plurality of single tubes arranged in the horizontal direction (Y direction) as one stage. When single tubes are stacked in a plurality of stages, first, as shown in FIG. 4 (a), there is a system in which the single tubes of each stage are stacked so that the axial centers are positioned on the same straight line in the vertical direction. However, in this method, the storage height H increases, so that the storage efficiency is inferior and the upper single tube and the lower single tube are in contact at one point and easily roll, so that the storage state becomes unstable and difficult to load.

  On the other hand, as shown in FIG. 4B, there is a method in which single tubes are stacked alternately at each stage so that the upper single tubes are mounted in the recesses between the lower single tubes. In this method, the storage height can be made lower than that shown in FIG. 4A, and the storage state of the single tube is also stable. However, the number of single pipes in each stage is alternated by one stage, and the number of single pipes is reduced by one by skipping one stage. Therefore, the storage efficiency is not always good.

Therefore, in the present embodiment, as shown in FIG. 4C, the number of single tubes in each stage is the same, and is shifted to the left and right for each stage. By doing so, the upper single pipe is mounted in the recess between the lower single pipes, and the storage state is stabilized and the storage efficiency is enhanced. In order to realize such a storage system, the side plates 2b and 2c are arranged apart by a distance L1 (distance between the inner surfaces). The distance L1 is
L1≈n × (single tube diameter) + (single tube radius)
(N is a natural number).

  In addition, a spacer 2d is disposed at the corner between the lower end portion of the side plate 2b or 2c (here 2b) and the bottom plate 2a so that the lowermost single tube is moved toward the side plate 2c. The spacer 2d moves the lowermost single pipe to the side plate 2c side by the radius of the single pipe. In the example of FIG. 4C, the width of the spacer 2d is the single tube radius (L3). The spacers 2c do not need to be disposed over the entire area of the corner in the Y direction, but may be disposed at both ends of the corner in the Y direction. In FIG. 4C, L1 = L2 (n × (diameter of single tube)) + L3. When the lowermost single pipe is shifted, the remaining single pipes are naturally shifted to the left and right for each stage.

Second Embodiment
FIG. 5A is an explanatory view of the structure of a single pipe processing apparatus 100 according to another embodiment of the present invention. The single pipe processing apparatus 100 is obtained by adding a function of attaching a tag to a single pipe as shown in FIG. 5B to the single pipe processing apparatus 1, and the configurations of the regulating members 20, 21 and the drive mechanism 30 are as follows. It is the same. The components having the same or similar functions as those of the single pipe processing apparatus 1 are denoted by the same reference numerals and description thereof is omitted.

  The single pipe processing apparatus 100 includes a temporary placement unit 110 that is disposed below the regulation pieces 20a and 21a and temporarily places a single pipe that has passed through the regulation pieces 20a and 21a. The temporary placement part 110 is formed integrally with the main body part 111 laid between the side plates 11 and 12 and the front end of the main body part 111, and a plurality of locking pieces 112 disposed intermittently along the X direction. With. The single pipe that has passed through the regulating pieces 20 a and 21 a is locked at the bent portion at the end of the locking piece 112 due to the inclination of the main body 111 and the locking piece 112.

  The single pipe processing apparatus 100 also includes an attachment mechanism 120 that is disposed below the temporary placement unit 110 and attaches a tag to the single pipe. The attachment mechanism 120 includes a slot 121 that houses a single tube to which a tag is attached. The slot 121 is constructed between the side plates 11 and 12, and both ends thereof are open. One opening end of the slot 121 is provided with a shutter 121a that is moved obliquely up and down by driving means (not shown), and partially opens and closes the opening end. Further, on the extension of the one opening end of the slot 121, a stopper 121b laid between the side plates 11 and 12, and an open / close bottom 121c connecting the stopper 121b and the bottom of the slot 121 are disposed. Yes. The open / close bottom 121c is rotated by driving means (not shown).

  The attachment mechanism 120 also includes a sheet roller 122 around which a sheet with a tag attached is wound. The sheet is formed by laminating a belt-like mount 122a, a tag 122b attached on the mount 122a at a predetermined interval, and a protective sheet 122c for protecting the attachment surface of the tag 122b. The protective sheet 122c is wound up by the winding roller 123 before the tag 122b is attached to the single tube. The sheet on which the protective sheet 122 c is wound is wound around the winding roller 125 via the pressure roller 124. When passing through the pressure roller 124, the tag 122 c is attached to the single tube disposed on the open / close bottom 121 c, and only the mount 122 a is wound around the winding roller 125.

  The sheet roller 122, the winding rollers 123 and 125, and the pressure roller 124 are disposed on the side plate 12 side. The tag 122b is, for example, a wireless IC tag of a seal or a seal type in which color or predetermined information is written. A single tube can be identified by the tag 122b.

  The single pipe processing apparatus 100 also includes a multi-indirect arm transfer robot 130 that transfers the single pipe temporarily placed on the temporary placement unit 111 to the attachment mechanism 120. The hand unit 131 of the transfer robot 130 is a magnet type hand unit, and holds and releases a single tube by energizing / releasing magnetic force. Needless to say, the hand unit 131 may be of other types. For example, one transfer robot 130 is disposed on each of the side plate 11 side and the side plate 12 side, and is operated synchronously.

  Next, the operation of the single pipe processing apparatus 100 will be described with reference to FIGS. First, the operation of the transfer robot 130 will be described with reference to FIG. In the transfer robot 130, the hand portion 131 enters between the locking pieces 112 from below the temporary placement portion 110 and is locked to the bent portion at the end of the locking piece 112 as indicated by a broken line in FIG. The single tube is held by magnetic force. When the single pipe passes through the regulating pieces 20a and 21a, the longitudinal direction thereof is directed in the X direction, and the temporary holding section 110 is also locked as it is. There is nothing. Thereafter, the single pipe is lifted, moved slightly to the side plate 14 side and lowered, and the single pipe is conveyed to the opening of the slot 121 as shown in FIG. Thereafter, the magnetic force of the hand portion 131 is released to release the holding of the single tube, and the single tube is introduced into the slot 121.

  On the other hand, when a sensor (not shown) detects the presence of a single pipe on the open / close bottom 121c, the take-up roller 125 winds up the mount 122a by a certain amount as shown in FIG. 123 also winds up a certain amount of the protective sheet 122c. The winding roller 125 winds the mount 122a by a certain amount, so that the sheet passes through the pressure roller 124, and the tag 122c is attached to the single tube on the open / close bottom 121c. Thereafter, the open / close bottom 121c is opened as shown in FIG. 7A, and the single tube to which the tag 122c is attached falls to the storage rack 2. Subsequently, as shown in FIG. 7B, the open / close bottom 121 c is again sealed, and the shutter 121 a is lowered to open the open end of the slot 121. As a result, the next single pipe moves onto the open / close bottom 121c. When a sensor (not shown) detects that a single tube is present on the open / close bottom 121c, the shutter 121a rises again to close the open end of the slot 121. By repeating the above operation, a tag for identifying the single pipe can be automatically attached to the single pipe, and the single pipe to which the tag is attached is stored in the storage rack 2.
