Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is useful for stacking angle irons, particularly scalene angle irons sent from manufacturing equipment, into a substantially prismatic shape with a predetermined number of horizontal and vertical angles for bundling. The present invention relates to a preferred angle iron stacking facility.

(Prior art and its problems) In order to bundle together a predetermined number of angle-shaped steels sent out from manufacturing equipment, for example, similar shaped steel sections W as shown in FIG. 19, it is necessary to bundle them together as shown in FIG. It is necessary to stack them vertically and horizontally in a predetermined number of approximately prismatic shapes.

Moreover, in order to prevent the cargo from collapsing easily during transportation in a stacked state, it is necessary to stack the products with inverted angle irons W', which are vertically inverted, interposed between horizontally adjacent angle irons W at every plurality of stages.

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 then transferred and stacked one stage at a time onto a stacking support. It was getting worse.

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

(Means for Solving the Problems) In order to solve the conventional problems as described above, the present invention has the following features:
A stacking support stand that can be raised and lowered adjacent to the end of a conveyance path for conveying angle iron horizontally at right angles to the length direction thereof is disposed so as to be movable back and forth in the conveyance direction of the conveyance path. A transfer device is provided for transferring a predetermined number of parallel angle steel groups gathered at a terminal transfer position onto the support base,
We propose an angle iron stacking facility in which a reversing means is disposed at the terminal transfer position of the conveyance path to turn a predetermined number of parallel angle iron groups into an upside-down state and deliver them to the transfer device. It is something.

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 arranged in parallel, and furthermore, this attachment 61
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. 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 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.

After the tip of the angle iron W sent out in the length direction from manufacturing equipment (not shown) is caught by a stopper, it is transferred in the transverse direction at right angles to the conveyance path l shown in FIGS. 1 and 2, and is placed in multiple rows. 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 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 the irregular angle iron WE by the sensors Sl and S2 is performed accurately.

When the irregular angle shape WE is detected by the sensors S1 and 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 connected to the sensor S1. S2 is kept open until it detects an angle iron W of the normal length, and when the angle iron W of the normal length is detected, the stopper sb is switched to the operating position, so that a plurality of angle irons are continuously fed. All of the 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 lOb in the open position, and then is received by the stopper 10a in the working position. Ru. When a predetermined number of angle irons W pass under the stopper 10b, the stopper 10b is switched to the operating position to stop the following angle irons W, and then a 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 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 part of the attachment 34a.

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 again 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 moved to the position shown in FIG. The movement is returned from the forward/lower limit position G shown in FIG.
is driven to rotate the rotary shaft 52 in the normal direction by a predetermined angle, and swing the support arm 53 of both lowering means 27 downward from the horizontal support position to the hanging position at the lowering limit position 2, as shown by the imaginary line in FIG. make it move. As a result, the angle iron W whose both ends are supported by the attachment 53a of the support arm 53 falls from above the support arm 53, but immediately after both ends of the angle iron W are separated from the support arm 53. The angle iron W is a pair of left and right table lifters 61 (stacking support base 21).
The table lifter 61 is kept on standby at the upper limit position so as to be transferred onto the attachment 61a.

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 1. 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), but 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. Before moving upward from the position B to the backward raising limit position B, the reversing means 24 shown in FIGS. 1, 5, and 6 is activated.

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 1. 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 Wc on a different side from the oblique side 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 Transfer trolley 25, second transfer trolley 26, and left and right ~
The pair of unloading means 27 causes the horizontally adjacent angle irons W to be placed in a vertically inverted state on top of the multiple stages of angle irons W already stacked on the stacking support stand 21 (a pair of left and right table lifters 61). As a result, the inverted angle bar W' shown in FIG. 20 is obtained.

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 piled angle irons are equal angle irons W as shown in FIGS. 19 and 20, so as shown in FIG. The steel sheets W are stacked so that some of the corners are located on the same vertical line. Therefore, the stacking support 21 is moved to the trolley 60.
Although the stacking support base 21 is configured to be movable back and forth, it is not necessary to move the stacking support base 21 using the cart 60 during stacking work. However, when stacking scalene angle bars WU as shown in FIG.
! is inclined toward the shorter side of the scalene angle steel WU. Therefore, if the lowering means 27 supports both ends of the scalene angle bars (5) and lowers them to the same position on the stacking support base 21, when the number of stacked stages increases, the scalene angle bars already stacked On the other hand, the scalene angle steel stacked on the short side comes off, and normal stacking cannot be performed.

Therefore, when stacking scalene angle bars WU, the 22nd
As shown in the figure, the support stand 21 (table lifter 61) for the stacking method is installed at each stage or every multiple stages.
Each scalene angle bar of the top layer that has been stacked earlier on the stacking support 21 is moved by a unit amount to the long side of U, and is placed approximately directly below each scalene angle bar WU that is lowered by the unloading means 27. If the steel WU is kept on standby, the stacking of the scalene angle steel WU can be carried out safely and reliably.

Of course, the wavy attachments 33a attached to each lifting platform 33, 34 of the first transfer trolley 25 and the second transfer trolley 26
, 34a, the wavy attachment 53a attached to the support arm 53 of the unloading means 27, and the wavy attachment 61a attached to the table lifter 61 constituting the stacking support base 21 are made of scalene angle steel WU as shown in FIG. A sawtooth-shaped one is used to match the shape of the Moreover, the stacking guide 61b shown in FIG.
is unnecessary because it does not function when stacking scalene angle steel. That is, when stacking scalene angle irons, an attachment 61a without a stacking guide 61b is used as shown in FIG. 22. Furthermore, as shown by the imaginary line in FIG. 22, the stacking guide 68, which is provided so as to be able to rise and fall, gets in the way when stacking the scalene angle bars WU, so it is kept in a lying state, but the stacking guide 68 is placed in a collapsed state. The stacking guide 68 may be erected in an inclined state according to the inclination of the stacking guide 68.

Furthermore, when handling a relatively thin and long scalene angle steel WU, when both ends of the scalene angle steel WU are supported by the support arms 53 of the lowering means 27, the scalene angle steel WU hangs down due to gravity. Since it has scalene sides, it curves in one direction in the front-back direction in plan view. Therefore, the scalene angle steel WU is lowered onto the stacking support base 21 by the unloading means 27 with the position of the central part in the longitudinal direction shifted in the front-rear direction, so that the length of the scalene angle steel WU to be lowered is The center part in the width direction is first attached to the support base 21.
It will come off in the front-back direction from the top layer of angle iron stacked above, and there is a risk that normal stacking will not be possible.

In order to eliminate this inconvenience, as shown in FIG. 22, parallel scalene chevrons are supported at both ends by the pair of left and right unloading means 27 and lowered onto the stacking support base 21 (table lifter 61). Stacking guides 80, 81 can be arranged on both sides of the lowering path of the steel group. These stacking guides 80, 81 can be arranged in parallel at one location or at multiple locations in the longitudinal center of the parallel scalene angle steel group to be lowered, at positions that do not interfere with other devices, and are arranged in parallel at the fixed frame 82, respectively. 83 with support shaft 84.85
The parallel scalene angle bar WU is lowered by being lowered by the springs 86 and 87 biasing the scalene angle iron WU toward the lifting path. It is desirable that the angle irons WU located at both the front and rear ends of the angle iron group be configured so as to be able to buffer the shock when they come into contact with the stacking guides 80, 81.

Note that, at least as shown in the figure, the stacking guides 80 and 81 on the side opposite to the side where the scalene angle iron WU curves and protrudes in plan view on the stacking support base 21 are , can be omitted. Furthermore, among the front and rear ends of the parallel scalene angle steel group, the stacking guide 8I adjacent to the side whose position differs depending on the number of pieces for one stage can be adjusted in position in the front and rear direction with respect to the fixed frame 83 as shown in the figure. It is desirable to attach it to a movable frame 88 that is attached to.

(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 a predetermined number of six angle irons vertically and horizontally without relying on manpower or a magnetic crane, which can contribute to a significant improvement in the efficiency of stacking work and a reduction in required costs.

Furthermore, according to the present invention, the stacking support is configured to be able to rise and fall as well as to be movable back and forth in the conveyance direction of the conveyance path, so even scalene angle iron can be stacked safely and reliably without any problem. Moreover, since the angle iron unloading position of the transfer device with respect to the stacking support is always substantially constant, the transfer device can also be configured relatively easily.
