Conventionally, for such stacking work, the angle irons sent out from manufacturing equipment were manually transferred and stacked one by one onto a stacking support, or the angle irons were stacked at right angles to their length. A method is adopted in which a predetermined number of angle irons are assembled in parallel on the end of a conveyance path that is transported horizontally, and this group of parallel angle irons is attracted by a magnetic crane and transferred one layer at a time onto a stacking support stand and stacked. It was getting worse.

All of these conventional methods require several full-time workers, are inefficient, and are expensive.

As shown in FIG. 0, 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.
Adjacent to the front end of the parallel angle iron group supported by a,
A stacking guide 68 that can swing up and down around a support shaft 67 and a cylinder unit 69 that swings up and down the stacking guide 68 are provided. Note that a fixed stacking guide 61b is erected at the rear end of the attachment 61a (the side adjacent to the terminal end of the transport path 1).

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 with the end of the conveyance path l. 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 chevron RW 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 angle iron W
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 having 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 81.32 is performed accurately.

When the irregular angle shape WE is detected by the sensor Sl, 32, 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 sensors Sl and S2 detect 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 passed 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 1. All of the irregular chevrons mWE received by the above are transferred onto the conveyor 18 for transporting the irregular chevrons, 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 pushers 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 transport path l in a state where they fit into the respective angles of the attachment 33a of the lifting platform 33, and are moved to the backward ascent 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 part of the attachment 34a.

Next, the lifting platform 34 (attachment 34a) of the second transfer cart 26 is moved as shown in FIG. The movement is made sequentially from the rearward ascent limit position E→(front position G-(reverse)→reverse descending limit position H-(raise)→reverse ascender limit position E), but a predetermined number of angle irons W are supported by the attachment 34a. When the elevator platform 34 is at the forward ascent limit position F, the seventh

In the horizontal support position, the support arm 53 is moved up and down together with the lifting table 51, and the support arm 53 is lifted up while being fitted into each of the chevrons of the attachment 53a on the support arm 53 and positioned.

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

-j←,'/ II -y The elevator rack gear 55 is driven by the lifter unit 56 to rotate the rotary shaft 52 in the normal direction by a predetermined angle, and the support arms 53 of both lowering means 27 are lowered as shown by imaginary lines in FIG. At the limit position I, it is swung downward from the horizontal support position to the hanging position. As a result, the angle iron W whose both ends are supported by the attachments 53a of the support arm 53 falls from above the support arm 53.
The table lifter 61 is moved to its upper limit so that immediately after both ends of the angle iron W are separated from the support arms 53, the angle iron W is transferred onto the attachments 61a of the pair of left and right table lifters 61 (stacking support bases 21). Wait in position.

A predetermined number of angle irons W, both ends of which are supported by the support arms 53 as described above, are placed between 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 steps, 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 manner, they will be transported one after another on the transport path l. A predetermined number of angle irons W are sequentially transferred onto the stacking support stand 21 (a pair of left and right table lifters 61), and each time the transfer of one stage is completed,
Alternatively, by lowering the table lifter 61 by a unit amount each time a certain number of stages of transfer are completed, the falling distance of the angle iron W from the downwardly swinging support arm 53 is reduced to a substantially constant minimum distance. can be maintained.

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

Therefore, when a predetermined number of angle irons W to be transferred upside down are received by the fixed stopper 11a, the lifting platform 33 of the first transfer cart 25 is moved to the backward lowering limit position A as shown in FIG. 1, 5, and 6 is activated before moving upward to the backward upward movement limit position B.

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, raise the reversing lifting platform 44 to the upper limit position.
As shown in FIG. 14, the Fumoto Nita rTIAAa pushes up the oblique side portion wb located on the front side of each angle iron W supported on the push-up pawl 43a, so in this state, the push-up lift Lower the platform 43 and attach each angle iron W.
By pulling down the push-up claws 43a from the inner corners Wa of the angle bars W, as shown in FIG. Transfer onto the support surface 42a. That is, each angle iron W is supported at a position slightly shifted rearward from the original support position on the flat support surface 42a, and at a hypotenuse part WC on a different side from the hypotenuse part wb pushed up by the reversing claw 44a. It turns out.

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
Each chevron in 3a is placed on the flat support surface 42a of the support platform 42;
Since it will push up the proverbial cheek WC of b-ascending 2-like W,
Each of the angle irons W further falls backwards, and as shown in FIG. 17, fits vertically upside down into the valley between the respective angles of the attachment 33a on the lifting platform 33, and is positioned and supported. It turns out.

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° as shown in FIG.

According to the above procedure, the angle iron W is moved between the pair of left and right table lifters 6 while interposing the inverted angle iron W 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.

Next, the features of the above embodiment of the present invention will be listed.

(1) Although it is also possible to use a fixed stand that cannot be raised or lowered as the stacking support stand 21 and to transport the stacked angle iron groups by a forklift or the like, as in the embodiment, the table lifter 61 The stacked angle iron group on the support stand 21 is moved up and down by the lowering of the support stand 21 onto the conveyor 70 for carrying out.
If the configuration is such that the stacked angle steel group can be transferred to the top, it is possible to carry out the stacked angle steel group efficiently.

(2) a pair of left and right liftable unloading means 27 for supporting both ends of a predetermined number of parallel angle iron groups and lowering them onto the stacking support base 21; Transfer means for transferring a predetermined number of parallel angle steel groups assembled at the loading position 22 onto the pair of left and right unloading means 27 (in the embodiment, the first transfer trolley 25 and the second transfer trolley 26)
In this case, it is better to use a transfer device that supports and lifts both ends of the parallel angle iron group gathered at the transfer position 22 and lowers it directly onto the stacking support 21. Also, it is possible to shorten the transfer distance in an unstable supporting state where both ends of the parallel angle iron group are supported.

(3) The transfer means transfers the group of parallel angle irons onto the pair of left and right unloading means 27 from an intermediate position between the terminal transfer position 22 of the transport path l and the stacking support stand 21. A second transfer trolley 26 that can reciprocate and transfer a predetermined number of parallel angle iron groups gathered at the terminal transfer position 22 of the transport path l onto the second transfer trolley 26 located at the intermediate position. When the first transfer cart 25 is reciprocally movable, the transfer from the transfer position 22 to the stacking support base 21 is performed using only one reciprocally movable transfer cart. In comparison, when one cart is in the forward movement for transfer, the other cart can be made to perform a backward movement to the transfer start position, so that the movement from the transfer position 22 to the unloading means 27 is The cycle time required for one transfer operation can be shortened.

(4) The pair of left and right lowering means 27 are moved to the lifting platform 51.
and a vertically swingable support arm 53 that cantilevers out from the lifting platform 51 toward the stacking support 21 and supports the end of the parallel angle steel group. When configured to be able to be raised and lowered by a table lifter 61 or the like, the supporting arms 53, which separately support both ends of the parallel angle iron group, are oscillated in synchronization.
When transferring the parallel angle iron group onto the stacking support 2I, a centering effect can be obtained, and it is possible to prevent the parallel angle iron group from shifting in the left and right lateral directions. By lowering the parallel angle iron group by a unit amount, the falling distance when the group of parallel angle irons is transferred onto the stacking support base 21 is always minimized, thereby reducing shock and preventing the load from collapsing. Further, by utilizing the downward movement of the stacking support stand 21, the stacked angle iron group can be transferred to the carrying-out conveyor 70 as described above.

(5) When the pair of left and right unloading means 27 are provided with a pusher 59 for centering at least the highest group of parallel angle irons transferred onto the stacking support stand 21, the stacked angle irons can be placed in the final position. It is possible to stack angle irons in an orderly manner by centering them. Further, even when the position of the lowering means 27 is adjusted in the left and right directions according to the length of the angle iron, there is no need to adjust the position of the centering pusher 59 alone, and the push/pull drive stroke of the centering pusher 59 is reduced. It is good that it is also constant.

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. Furthermore, although the structure is configured to automatically sort and take out the irregular angle iron WE, it is possible to automatically sort and take out the irregular angle iron
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.
