3 and a belt feeder 5 for supplying a tying belt corresponding to the tying position of the tube rod material 1.
5 and 5.

The bundling device 13 is used when the tube rod 1 is formed.
The binding machine 54 is evacuated to the outside of the supply path of the tube rod 1 by the carrier 52, the binding machine 54 is moved to a position corresponding to the binding position at the time of binding, and it is already formed by the binding belt supplied by the belt feeder 55. The tube rod material 1 is bound.

(D) Dispensing Device 14 As shown in FIG. 2, the dispensing device 14 comprises a chain conveyor driven by a motor 61. A plurality of chain conveyors 62 are arranged side by side in the longitudinal direction of the pipe rod 1 (the direction perpendicular to the feeding direction). The chain conveyor 62 has its carry-in end extending below the pipe rod forming region of the forming machine 12,
The transport surface is positioned above the bottom molding surface 42A of the bottom frame 42 at the lowest position (dispensing level). Therefore, when the bottom frame 42 is lowered to the payout level, the tube rods 1 bound by the molding machine 12 are naturally transferred to the chain conveyor 62 and paid out.

The binding processing apparatus 10 has the following characteristic structure and operational effects.

(1) Supply guide 23 of the supply device 11 (see FIG.
The supply guide 23 is configured by a wedge-shaped beam that becomes thinner from the base end side that is tilted and supported by the second supply rail 22 side toward the protruding tip side when the above-mentioned setting from the standby position to the working position is set. It Then, in the supply guide 23, the upper surface of the wedge-shaped beam is a downwardly inclined transfer surface 23A and the lower surface thereof is a horizontal surface 23B.

The lower surface of the supply guide 23 is preferably as small as 5 mm or less, for example, 5 mm or less.

Further, it is desirable that the supply guide 23 is made of an elastic material such as spring steel which has a high yield strength and is flexible. According to this, the supply guide 23 set to the working position bends downward due to the weight of the tube rod material 1 (upper layer tube rod material) received on the upper surface thereof, and the bottom forming surface 42A in the tube rod material forming area is formed. Alternatively, it can be deposited on the lower layer tube rod and the upper layer tube rod can be transferred from the wedge tip to the bottom forming surface 42A or the lower layer tube rod with a minimum drop.

Further, the thickness to of the wedge tip portion of the supply guide 23 and the thickness t of the base portion (see FIG. 4 (A)) are as shown in FIG.
It is necessary to properly select and adjust the size according to the size, the retracting distance of the supply guide 23 from the working position to the standby position, and the retracting direction.

Further, the retreat speed v of the supply guide 23 from the working position to the standby position needs to be appropriately selected and adjusted according to the size of the tube rod material 1.

For example, the outer diameter of the tube rod 1 is 15.9 mm, the movement distance of the supply guide 23 is 900 mm, and the movement direction (wedge slope).
If the gradient is 1/25, then to is 4mm, t is 40mm, and v is 10.5.
m / min.

Therefore, in the supply device 11, since the supply guide 23 has a thick wedge shape at the base end side,
A constant cross-sectional strength can be secured when receiving and supporting the pipe rod 1 in a cantilevered state in which it projects from the side of the supply rail 22 to just above the pipe rod forming region of the molding machine 12. Then, by setting the horizontal lower surface 23B of the supply guide 23 directly above the tube rod material forming region with a slight gap, the upper surface of the supply guide 23 serves as a downwardly inclined transfer surface 23A.
While allowing the pipe rod 1 to be received in the transfer state, the distance that the pipe rod 1 falls from its upper surface to the pipe rod forming region can be reduced. For this reason, noise at the time of dropping can be reduced, and damage due to collision can be reduced.

(2) Alignment guide 71 of the feeder 11 (see FIG. 5)
The supply device 11 is provided above the supply guide 23 set at the working position with a certain distance from the supply guide 23 to form the pipe rod 1
Alignment guides 71 are installed to guide the in one row.

The alignment guide 71 is hung from the support frame 72 via the pantograph 73, and is set from the upper standby position to the working position by the expansion and contraction of the pantograph 73 by the operation of the motor 74, and the distance H from the supply guide 23 is adjusted. It is possible. H is preferably 1.5 times or less the outer diameter of the tube rod 1.

The alignment guide 71 is the supply guide 23.
In order to prevent the occurrence of biting of the tube rod material 1 between
It is recommended to use a bite prevention mechanism that uses a spring.
This biting prevention mechanism can be configured by interposing a spring 71A between the lower frame of the pantograph 73 and the alignment guide 71.

Therefore, in the supply device 11, the pipe rod 1 transferred from the supply rail 22 to the supply guide 23.
However, the alignment guide 71 prevents jumping upward, and there is no need to go over the tube rod material 1 that was previously supplied to the supply guide 23 and stayed there, thus forming a single bundle of the bundled load. The tube rod 1 can be reliably and easily aligned on the supply guide 23.

(3) The pushing device 81 of the feeding device 11 (see FIG. 6,
(See FIG. 7) The supply device 11 arranges the tube rod material 1 received in the supply guide 23 in the tube rod material alignment area on the supply guide 23 (the bottom frame 44 of the molding machine 12, the molding surface 44A of the auxiliary frame 45,
Pushing device 8 for pushing into a region whose position is regulated by 45A)
1 is provided.

The pushing device 81 slidably supports a movable base 83 on a guide rail 82 extending along the supply rail 22, and slides a pair of left and right pushing rods 84 on the movable base 83 via a turning cylinder 83A. The left and right pushing heads 85 which are freely supported and are capable of undulating by rotating 90 degrees at the tips of the pushing rods 84 are provided. The pushing rod 84 is the swivel tube 8.
3A is spline-coupled and can be swiveled integrally with the swivel cylinder 83A.

The pushing device 81 rotates the swivel cylinder 83A 90 degrees by rotating the swivel cylinder 83A 90 degrees by meshing the rack 87 driven by the undulating cylinder 86 installed on the movable table 83 with the pinion 88 provided on the swivel cylinder 83A. The pushing head 85, which turns together with the cylinder 83A, is set to a prone position where it does not buffer the pipe rod 1 on the supply rail 22 and a standing position where a pushing force is applied to the pipe rod 1 received on the supply guide 23. To do.

The pushing device 81 moves the movable base 83 forward and backward by the forward / backward moving cylinder 81A to move the movable head 83 forward and backward.
Of the length measuring cylinder 8 fixed to the movable table 83 after the pushing head 85 is set to the upright position by the operation of the undulating cylinder 86.
The right and left upright pushing heads 85 are pushed into the right and left two positions in the longitudinal direction of the pipe rod 1 to the proper pushing positions of this time through the connecting beam 90 by means of 9.

The tube rod material pushing surface of the pushing head 85 is a roller surface 91 formed by a large number of rotatable rollers. Each roller forming the roller surface 91 has its roller axial direction parallel to the longitudinal direction of the tube rod material 1 on the supply guide 23.

The length measuring cylinder 89 has a length measuring function. Then, the pushing device 81 determines the pushing position of the pushing head 85 based on the length measurement output of the length measuring cylinder 89, and further calculates the number of pipe rods received on the supply guide 23 so that the determination can be performed.

That is, the length measuring cylinder 89 is, for example, an NSD.
The company's Silnack cylinder can be adopted, magnetic materials are incorporated into the cylinder rod at equal pitches, and an exciting coil for applying an AC voltage and an induction coil for measuring the induced voltage are installed on the cylinder casing side. The amount of rod movement between the pitches is measured by the phase difference of 1 and the number of movement pitches is measured by counting the repetition of phase changes, and as a result, the total amount of rod movement is obtained.

The method of determining the number of tube rods using the length measuring cylinder 89 is as follows. That is, the pipe rod material pushed on the supply guide 23 comes into contact with the side frame 44 or the auxiliary frame 45 and stands still (FIG. 10 (A),
(See (B)). Here, the supply guide 23 and the main frame 4
The distance L0 from the intersection with 1 to the origin position of the tip of the pushing head 85 and the angles θ1 and θ2 shown in the figure are fixed values.
, X2, X3 can be measured by a frame positioning device, and the diameter R of the pipe rod is known. Therefore, the distance L from the origin position of the tip of the pushing head 85 to the pipe rod tip is geometrically defined by the following (1 ) And (2). By subtracting the moving amount of the pushing head 85, that is, the rod moving amount of the measuring cylinder from this distance L, the width W of the aligned pipe rods is obtained, and the number data is obtained by dividing by the diameter R of the pipe rods. .

The position data X of each frame determines which of the side frame 44 and the auxiliary frame 45 the tube rod is in contact with.
It is possible to judge from 1, X2, and X3, but in this device, when each lower hexagonal step (not including steps connecting diagonals) is supplied to the side frame, the hexagonal upper side (diagonal Each stage (including the stage to connect) is to be in contact with the auxiliary frame.

(A) When the pipe rod is in contact with the side frame 44

[Equation 1]

(B) When the pipe rod is in contact with the auxiliary frame 45

[Equation 2]

Therefore, in the feeding device 11, the pushing device 81 pushes the pipe rod material 1 received on the feed guide 23 into the pipe rod material alignment region, and the pipe rod material 1 is left in the pipe rod material alignment region. Make sure that they are aligned. Further, when changing the setting of the supply guide 23 from the working position to the standby position, the pushing device 81
Prevents the tube rods 1 from accommodating the return movement of the supply guide 23 and holds the tube rods 1 in the tube rod alignment region. Therefore, the tube rod material 1 is transferred to the tube rod material forming area of the molding machine 12 while being properly aligned on the supply guide 23, and is given an appropriate packing form.

The pushing head 85 of the pushing device 81 has
By providing the tube rod pressing surface 91 composed of a roller surface, the tube rods 1 are aligned without interfering with the free rotation of the tube rods 1 on the supply guide 23 which is moved back from the working position to the standby position. The state can be maintained stably.

The number of tube rods on the supply guide 23 can be determined by the pushing position of the pushing head 85 of the pushing device 81. Therefore, the tube rods 1 can be aligned on the supply guide 23, and at the same time, the adequacy of the number of lines can be confirmed.

(4) Tube End Alignment Device 101 of Molding Machine 12 (See FIG. 8) The molding machine 12 is arranged on one side or both sides of the tube end material of the tube bar material 1 being formed in the tube bar material forming area. End aligning device 10 for aligning pipes
1 is provided. The pipe end aligning device 101 mounts a carriage 102 that can move forward and backward on the side of the molding machine 12 on a guide rail 103, and rotates a wheel 105 by a rotation operation force applied to a handle 104 to rotate the carriage 102 to the guide rail. 1
03, and the carriage 102 is stopped by inserting the stop pin 106 provided on the carriage 102 into any one of a large number of stop holes 107 defined along the guide rail 103. Air cylinder 1 on 102
The pipe end aligning plate 109 advanced at 08 aligns the pipe ends of the pipe rod 1 being formed in the pipe rod forming region.

Here, the pipe end aligning plate 109 of the pipe end aligning device 101 collectively bundles the pipe rod materials 1 for one layer, which have been aligned by the supply guide 23 and then transferred to the pipe rod material forming region. Align the edges.

The operator of the pipe end aligning device 101 should hold the retaining pin 106 described above in accordance with the expected position of the pipe end, which is determined according to the total length of the pipe rod 1 being formed this time. 1
07 is set and the truck 102 is stopped.

Therefore, in the molding machine 12, the tube rod material 1 whose tube ends are aligned by the aligning roller 24 of the supply device 11 is then passed through the supply rail 22 and the supply guide 23 and then the tube rod of the molding machine 12. Even if the pipe ends are misaligned before being transferred to the material forming region, the pipe ends 1 transferred to the pipe forming region can be reliably aligned for each layer of the bundled load. And

(5) Molding adapters 111 of the molding machine 12, 1
12 (see FIG. 9) The molding machine 12 includes molding adapters 111, 1 capable of partitioning and forming tube rod material molding regions on the molding surfaces 41A, 44A of the main frame 41 and the side frame 44 facing each other.
12 is removable.

The molding machine 12 not only obtains a hexagonal bundled shape by partitioning and forming the aforementioned hexagonal tube rod material molding region by the molding surfaces 41A and 44A, but also the molding adapter 1
For example, a U-shaped tube rod material forming region is defined by 11, 112, and as a result, a circular bundled packing shape can be obtained.

The molding adapters 111, 112 can be prepared in various shapes according to the shape of the bundled load.

Therefore, in the bundling apparatus 10, the shape of the tube rod material molding region defined by the main frame 41, the bottom frame 42, and the side frame 44 of the molding machine 12 is the main frame 41 and the side frame. The attachment and detachment of the molding adapters 111 and 112 to and from each of the parts 44 causes a great difference. This makes it possible to easily and drastically change the bundling load.

The bundling operation by the bundling processing device 10 will be described below (see FIG. 1). The bundling machine 12 has the bottom frame 42 set to the first-stage loading position and the swing frame 43 is set to the working position, and the side frame is set to the side position. The frame 44 and the auxiliary frame 45 are in the tube rod material forming region forming position. Further, the second stop lever 29 of the supply device 11 has a stop position, the supply guide 23, and the alignment guide 7.
1 is set to each standby position. Then, the pipe rod material 1 supplied from the side of the first supply rail 21 onto the second supply rail 22 is stopped by the second stop lever 29 by the first stop lever 28 by two for the first stage ( See FIG. 1A).

Next, the feeding guide 2 of the feeding device 11
3, the alignment guide 71 is changed from the standby position to the working position, and the side frame 44 is moved from the second supply rail 22 side.
Be extended to the side of. After that, the second stop lever 29 is opened by the cylinder 32, and the two tube rod materials 1 are released. The two pipe rod materials 1 are transferred on the downwardly inclined transfer surface 23A of the supply guide 23, and the positions thereof are regulated by the side frames 44 to be received in the pipe rod material alignment region on the supply guide 23. At this time, the tube rod material 1 is guided upward by the alignment guide 71 (see FIG. 1B).

Then, the pushing device 81 of the feeding device 11 is actuated to push the two pipe rods 1 received in the feed guide 23 into the pipe rod alignment region on the feed guide 23. afterwards,
The supply guide 23 returns to the standby position, and the two tube rods 1 are transferred onto the bottom frame 42 (see FIGS. 1C and 1D). At this time, since the pushing device 81 holds the two pipe rods 1 in the pipe rod alignment region and the supply guide 23 is constituted by a wedge-shaped beam, the dropping distance is small and the pipe rod 1 Is transferred stably. After that, the alignment guide 71 and the pushing device 81 return to the standby position.

On the other hand, the second stop lever 29 is reset to the stop position for receiving the pipe rod 1 of the next stage, that is, the second stage after releasing the two pipe rods 1 in the above, and the second stage Then, the three tube rod materials 1 are stopped (see FIG. 1C).
Further, the pipe end aligning device 101 of the molding machine 12 aligns the pipe ends of the two pipe rods 1 transferred on the bottom frame 42 (see FIG. 1D).

After the two tube rods 1 have been transferred onto the bottom frame 42 as described above, the bottom frame 42 is set to the second stacking position (see FIG. 1D). After that, as in the case of the above-mentioned first-stage loading, the process shown in FIG.
The step (D) is repeated, and the three tube rods 1 of the second stage and the two tube rods 1 of the third stage are stacked one by one, and the regular hexagonal shape of FIG. 1 (E) is obtained. The united package of is molded.
At the time of this loading, the fall position of the third-stage tube rod material 1 is regulated by the auxiliary frame 45, and a stable regular hexagonal bundled loading shape is secured.

As described above, when the stacking work of the forming machine 12 into the tube rod forming area is completed, the retracted binding machine 54 is moved by the carrier 52 on the moving rail 51 to a predetermined binding position. It is set (see FIG. 1E).

Then, the binding machine 54 performs a predetermined operation to bind the tube rod materials 1 stacked in a regular hexagon by the belt supplied from the belt feeder 55 provided on the floor. Then
Similarly, the binding machine 54 moves to another binding position and binds (see FIG. 1 (F)). When the bundling at a predetermined location (two locations in this embodiment) is completed, the bundling machine 54 moves on the moving rail 51 as at the time of setting and is evacuated to a standby position outside the supply path of the pipe rod 1.

Simultaneously with the evacuation of the binding machine 54, the swing frame 43 of the molding machine 12 is swung to set the side frame 44 to the payout position, and the bottom molding surface 42A of the bottom frame 42 is set to the chain conveyor of the payout device 14. 6
It is lowered to the payout level below the conveyance surface of No. 2 (see FIG. 1G). Therefore, the binding tube bar 1 is transferred onto the chain conveyor 62.

Next, the motor 61 is driven and the pipe material 1 is carried out to the stock conveyor side by the chain conveyor 62 (see FIG. 1 (H)). At the same time, the side frame 44 is returned to the working position for forming the tube rod forming region, and the bottom forming surface 42A of the bottom frame 42 is set up to the first-stage stacking position (see FIG. 1A). Then, prepare for the next binding operation.

In the practice of the present invention, the supply device 11, the molding machine 12, and the payout device 1 which constitute the binding processing device 10.
Each of 4 may be divided into a plurality of units corresponding to each of a plurality of positions defined in the longitudinal direction of the pipe rod 1, and the units may be separately installed. It is possible to improve the sex.
