From the structure 6h The previous word Fu ancient law
A triangular wave-shaped attachment 53a is detachably attached to support the end portions of a predetermined number of angle irons W extending one inch in front of each other. Further, a centering pusher 59 is disposed on the movable base 48 and is supported by a slide guide rod 57 so as to be freely retractable and is pushed and pulled by a cylinder unit 58.

The stacking support 21 is shown in FIGS. 2, 9, and 1.
As shown in Figure O, it is composed of a pair of left and right table lifters 61 provided on a trolley 60. The trolley 60 is supported on a guide rail 62 via wheels 63 and 64 so as to be able to reciprocate in the transport direction of the transport route l,
The drive shaft 65 of one wheel 63 is driven forward and backward by a drive motor 66 to move it back and forth. On each table lifter 61, a pair of left and right triangular wave-shaped attachments 61a that support a predetermined number of parallel angle irons W are removably installed in parallel.
At the front of the parallel angle steel group supported by a, there is @Cai+7. A stacking guide 68 that can be freely recessed around the upper shaft 67
and a cylinder unit 69 that makes the stacking guide 68 rise and fall. Note that the rear end of the attachment 61a (the side adjacent to the end of the conveyance path 1)
A fixed stacking guide 61b is provided upright.

As shown in FIG. 1, FIG. 2, and FIG. 9, the table when a plurality of rows of unloading conveyors (supporting chain conveyors) 70 are at the lower limit position so as to be continuous at the end of the conveyance path 1. It is arranged at a higher level than the attachment 61a of the lifter 61. 71 is the carrying out conveyor 7
This is a motor that rotationally drives the drive shaft 72 of 0.

The angle iron W sent out in the length direction from manufacturing equipment (not shown) is transferred at right angles and laterally onto the conveyance path 1 shown in FIGS. The supporting chain conveyors 2a and 2b convey the material horizontally at right angles. At this time, the position of one end of each angle iron W (the end on the side that is received by the stopper) WR varies slightly in the left and right directions, so when the angle iron W passes directly beside the side stopper 5, it is necessary to manually By moving each angle iron W toward the side stopper 5 and bringing one end WR into contact with the side stopper 5, the positions of the one ends WR of each angle iron W are aligned. It is also possible to press the angle iron W onto the side stopper 5 automatically by a mechanical device instead of manually.

Each angle iron W, whose one end WR is aligned using the side stopper 5, passes under the stopper 6b in the open position, and is forcibly stopped by the pair of left and right stoppers 6a in the operating position, so that a predetermined number of angle irons W are aligned. Steel W is stopper 6b
When passing below, the stopper 6b is lowered to the operating position to stop the following angle iron W. As a result, the predetermined number of angle irons W that have passed under the stopper 6b are pressed against the pair of left and right stoppers 6a due to friction with the continuously driven chain conveyor 2a, and are corrected to a horizontal position perpendicular to the conveyance direction. . When a certain period of time has elapsed, the stopper 6a is opened and the iron is sent out by the chain conveyor 2a, and when all the angle irons W have passed the position of the stopper 6a, the stopper 6a is switched to the operating position again, and the stopper 6b is opened. Subsequent angle iron W
is sent to the position of the stopper 6a.

The angle iron W whose orientation has been corrected using the stopper 6a is
Next, it passes over the lifter 7 for irregular angle irons, and the irregular angle iron WE which is not of a predetermined length is stopped on the lifter 7 by the stopper 8a. This irregular shaku yamagata IW
For automatic selection of E, for example, a sensor SI such as a transmission type light switch for detecting the other end WL of the short angle iron is installed at a position immediately before the stopper 8b, and a sensor SI such as a transmission type light switch for detecting the other end WL of the long angle iron is placed, for example. When a long angle shape longer than a predetermined length is to be used as a random angle shape WE, the random angle shape WE is automatically detected by turning on detection of both sensors S1 and S2. When a short angle iron with a length shorter than a predetermined length is used as a random angle iron WE, when the sensor S1 is in the detection ON state, the sensor S2 is in the detection OFF state, so that the random angle steel WE can be automatically detected. At this time, as described above, the position of one end WR of the angle iron W is aligned using the side stopper 5, and the angle iron W is corrected to a sideways posture perpendicular to the conveyance direction using the stopper 6a. Therefore, the automatic sorting of irregular angle iron WE by the sensors SL and S2 is performed accurately.

However, sensor S1. When the irregular angle shape WE is detected in S2, the stopper 8a is switched to the operating position at a predetermined timing, and the detected irregular angle shape WE is stopped at the stopper 8a. The stopper 8b is kept open until the sensor 31, 32 detects the angle iron W of the normal length, and when the angle iron W of the normal length is detected, the stopper 8b is switched to the operating position. All of the continuously fed irregular length angle iron WE can be collected and stopped before the stopper 8a, and the angle iron W of normal length can be kept on standby without being fed onto the lifter 7.

After a certain period of time has elapsed after the stopper 8b is switched to the operating position, the lifter 7 is raised to the upper limit position, and then the transfer pusher 19 is driven forward by the cylinder unit 20, so that the stopper 8a is moved on the transport path l. All of the irregular angle iron WE received by is transferred onto the conveyor 18 for transporting the irregular angle iron, and can be transported to a predetermined location by the conveyor 18. The stoppers 8a and 8b are opened after the lifter 7 has been lowered to a lower limit position at a lower level than the transport path 1.

The angle iron W of normal length, which is conveyed by passing under the stoppers 8b and 8a in the open position, then passes under the stopper 10b in the open position, and then is received by the stopper 10a in the working position. Predetermined number of angle iron W
When the stopper 10b passes under the stopper 10b, the stopper 10b is switched to the operating position to stop the following angle iron W, and then the pair of left and right centering bushers 9a.

9b is driven forward by cylinder units 14a and 14b, and a predetermined number of parallel angle irons W of normal length are centered at a predetermined position. Centering pusher 9
After returning the a and 9b, the stopper 10a is opened, and the parallel angle steel group that has been centered is sent out by the chain conveyors 2a and 2b.
A is switched to the operating position and the stopper 10b is opened to send the waiting following angle iron W to the centering position.

The angle iron W sent out from the centering position is received by the fixed stopper 11a after passing under the stopper 11b in the open position.

The stopper 11b is switched to the operating position when a predetermined number of angle irons W pass under the stopper 11b, and the subsequent angle irons W are stopped and on standby. Next, the lifting platform 33 (attachment 33a) of the first transfer cart 25 in the transfer device 23 is driven up and down by the cylinder unit 32 and by pushing and pulling the cart 25 by the cylinder unit 30. As shown in FIG.
The motor is continuously moved in the order of (forward) → forward upper limit position C → (lower) → forward lower limit position D → (reverse) → backward lower limit position A. As a result, the predetermined number of angle irons W received by the fixed stopper 11a are lifted from the conveyance path 1 in a state that they are fitted into each angle part of the attachment 33a of the lifting table 33, and are moved to the backward and upward limit position. It is transferred onto the lifting platform 34 of the second transfer cart 26 that is waiting at E. Also on this elevating table 34, each angle iron W is positioned by fitting into each angle shaped part of the actuator h34a.

Next, the lifting platform 34 (attachment 34a) of the second transfer cart 26 is moved as shown in FIG. Backward ascent limit position E → (forward) → Forward ascent limit position F → (descend) → Forward descending limit position G- (reverse) → Backward descending limit position H →
(Rise)→Reverse ascent limit position E. When the lifting platform 34, which supports a predetermined number of angle irons W by the attachment 34a, is in the forward ascent limit position F, as shown in FIGS. 7 and 8. As shown in FIG. Both ends of W are transferred to the tip of the support arm 53 that rises together with the lifting platform 51 in a horizontal support position, and are lifted up while being fitted into the chevrons of the attachment 53a on the support arm 53 and positioned. It will be done.

The lifting platform 51 of the lowering means 27 is lowered and returned from the upper limit position J to the lowering limit position I by the cylinder unit 50, but at this time the lifting platform 34 of the second transfer cart 26 has already been moved as shown in FIG. It has returned backward from the forward lowering limit position G to the backward lowering limit position H. A pair of left and right unloading means 2
When the lifting platform 51 of No. 7 reaches the lowering limit position I, the cylinder unit 56 shown in FIG. 8 drives the lifting rack gear 55 to rotate the rotary shaft 52 forward by a predetermined angle, as shown by the imaginary line in FIG. The support arms 53 of both lowering means 27 are swung downward from the horizontal support position to the hanging position at the lowering limit position (2). As a result, the angle iron W supported by the attachment 53a of the support arm 53 will fall from above the support arm 53, but immediately after the both ends of the angle iron W are separated from the support arm 53. The table lifter 61 is kept on standby at the upper limit position so that the angle iron W is transferred onto the attachment 61a of the pair of left and right table lifters 61 (stacking support bases 21).

A predetermined number of chevrons @W whose both ends are supported by the support arms 53 as described above are placed on a pair of left and right table lifters 6.
1 (stacking support base 21), the lifting rack gear 55 is raised by the cylinder unit 56 shown in FIG. Centering pusher 5 shown in
9 is moved forward by the cylinder unit 58 to center the angle iron W supported on the attachment 61a of the table lifter 61.

With the above, the transfer of one stage of angle iron W to be stacked on the stacking support stand 21 (a pair of left and right table lifters 61) has been completed, and in the same way, the table lifter 61
), by lowering the table lifter 61 by a unit amount each time the transfer of one stage is completed, or each time the transfer of a certain number of stages is completed, The falling distance of the angle iron W from the support arm 53 swinging downward can be maintained at a substantially constant minimum distance.

Once the predetermined number of stages have been stacked, the angle iron W must be turned upside down and transferred as shown in FIG.

For this reason, a predetermined number of Yamagata I pieces should be transferred upside down.
When the RW is received by the fixed stopper 11a, before moving the lifting platform 33 of the first transfer cart 25 upward from the backward lowering limit position A to the backward raising limit position B as shown in FIG. , actuate the reversing means 24 shown in FIGS. 5 and 6.

That is, each of the lifting tables 42 to 44 of the reversing means 24 can be raised and lowered individually by the cylinder units 39 to 41, but first, as shown in FIG. 12, the supporting lifting table 42 is moved to the upper limit position. and lift a predetermined number of angle irons W received by the fixed stopper 11a from above the transport path l. Next, the lifting platform 43 for pushing up is raised to the upper limit position, and the claw 43a for pushing up is entered into the downward inner corner Wa of each angle iron W supported on the flat support surface 42a of the lifting platform 42 for support. Then, each angle iron W is pushed up to the flat support surface 42a by the push-up claw 43a.
lift it from As a result, as shown in FIG. 13, each angle iron W is in an unstable state in which it can swing from side to side on the push-up pawl 43a.

Next, when the reversing lifting platform 44 is raised to the upper limit position,
Each reversing claw 44a on the reversing lifting platform 44 is
As shown in the figure, since the oblique side portion wb located on the front side of each angle iron W supported on the pushing up pawl 43a is pushed upward, the lifting table 43 for pushing up is lowered and each angle iron is pushed up in such a state. Push up claw 4 from inner corner Wa of W
By pulling down 3a, each angle iron W is transferred onto the flat support surface 42a of the support platform 42 while falling in the direction in which the oblique side portion wb stands up, that is, backward. In other words, each angle iron W is placed in the reversing claw 4 at a position slightly shifted rearward from its original support position on the flat support surface 42a.
It is supported at the oblique side part We on a different side from the oblique side part wb pushed up by 4a.

Therefore, after lowering the reversing lifting platform 44 as shown in FIG. 16, the lifting platform 33 of the first transfer cart 25 is raised from the backward lowering limit position A to the backward raising limit position B shown in FIG. By doing so, the attachment 3 on the lifting platform 33
3a, each angle iron W is supported in an overturned position on the flat support surface 42a of the support lifting table 42.
Since the hypotenuse part WC of is pushed up, each angle iron W
further falls backwards, and as shown in FIG. 17, fits vertically upside down into the valleys between the respective chevrons of the attachment 33a on the lifting table 33, and is positioned and supported.

As mentioned above, the predetermined number of angle irons W transferred onto the attachment 33a on the lifting platform 33 of the first transfer cart 25 in an upside-down state with their position shifted backward by half a pitch are The transfer cart 25, the second transfer cart 26, and the pair of left and right unloading means 27 are used to place the items onto the multiple stages of angle iron W that have already been stacked on the stacking support stand 21 (the pair of left and right table lifters 61). Since it is transferred in a vertically inverted state between horizontally adjacent angle irons W, it becomes an inverted angle iron W' shown in FIG.

By the above procedure, the angle irons W are moved between the pair of left and right table lifters 6 with the inverted angle irons W' interposed at every multiple stages.
The angle irons W can be stacked a predetermined number of stages on one attachment 61a, but the stacking of angle irons W on the pair of left and right table lifters 61 is stabilized between the front and rear stacking guides 68 and 61b, as shown in FIG. It is carried out according to Then, when the predetermined number of stacking is completed, the first
As shown by the imaginary line in FIG. 8, the table lifter 61 (attachment 61a) has descended from the stacking start level L1 to the stacking end level L2. While lowering it to position L3, the stacking guide 68 standing up on the unloading direction side is rotated forward and downward by the cylinder unit 69 shown in FIG. After that, by driving the carrying-out conveyor 70, the stacked angle bars that have been transferred from the table lifter 61 onto the carrying-out conveyor 70 can be carried out by the carrying-out conveyor 70 toward the bundling equipment.

In the above embodiment, the stacking support 21 is moved to the terminal transfer position 22 of the transport path l so that scalene angle irons WU can be stacked without any trouble as shown by the imaginary lines in FIG.
Although the stacking support table 21 is configured to be movable back and forth in the same direction as the transfer direction from the stacking support table 21 to the stacking support table 21, the position of the stacking support table 21 can be fixed when the scalene angle iron WU is not handled. In addition, although it is configured to automatically sort and take out the irregular angle iron WE, the front side is the irregular angle iron WE.
If it is possible to remove this configuration, this configuration can also be omitted.

(Operations and Effects of the Invention) As described above, according to the angle iron stacking equipment of the present invention, by conveying the angle iron sent out from the manufacturing equipment horizontally at right angles to its length direction, One stage of parallel angle steel groups assembled at the terminal transfer position can be sequentially stacked on a stacking support by a transfer device. Then, the angle irons to be stacked upside down are turned upside down by the reversing device at the transfer position and delivered to the transfer device, and the angle irons that are to be stacked on the stacking support are placed at the top of the pile. They can be stacked upside down between horizontally adjacent angle irons in the upper tier.

In this way, it is possible to mechanically stack angle irons in a predetermined number vertically and horizontally without relying on manpower or magnetic cranes, which can contribute to greatly improving the efficiency of stacking work and reducing the required costs.

Further, according to the present invention, the reversing means includes a support elevator having a flat support surface, and a push-up pawl that fits into a downwardly facing inner corner of the angle iron lifted from the conveyance path by the flat support surface. and a reversing lifting table having a reversing claw that pushes up one oblique side of the angle-shaped steel that is swingably supported by the lifting claw, and the transfer device includes: A lifting platform (implemented) having a wavy attachment that changes the angle iron placed in an overturned state on the flat support surface into an up-and-down inverted position and supports it at the trough by pushing up the reversing claw and lowering the pushing-up claw. In the example, an elevating platform 33) for the first transfer cart 25 is provided, and when the reversing means is not operating, the angle bar in the upright position at the transfer position is supported by the angle section of the wavy attachment. Therefore, after the support lifting table, the pushing-up lifting table, and the reversing lifting table are raised in sequence, the pushing-up lifting table and the reversing lifting table are sequentially lowered, and then the By simply raising the lifting platform, each of the parallel angle irons can be turned upside down and shifted by half a pitch in the parallel direction, and then supported by the lifting platform of the transfer device, allowing the entire group of parallel angle irons to be supported by the lifting platform of the transfer device. Compared to the case of flipping the bar upside down by pinching it from above and below, the space required for flipping is smaller, and the transfer device itself can be used both for transferring upright angle bars and for transferring inverted angle bars. Therefore, the structure is much simpler than in the case where a dedicated transfer device is required for each, and it can be implemented at a low cost.
