Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for stacking formed steel sheets such as roofing materials.

[0002]

2. Description of the Related Art Corrugated steel sheets (roof decks) used as roofing materials for factories and warehouses are sequentially stacked at the exit of a molding machine. Moved to a position. Therefore, a stacking device is conventionally installed at the exit of the molding machine.

A conventional stacking device has a side wall along one side of a formed steel plate and an upper wall extending from the upper end of the side wall onto the formed steel plate. The other side facing the side wall is open,
Further, a pair of opposing horizontal support rollers are attached to the ends of the side wall and the upper wall at regular intervals.

[0004] The formed steel sheet coming out of the forming machine is sent out onto the above-mentioned support roller, and when the feeding is completed, each support roller is rotated downward by the action of the air cylinder, and the formed steel sheet is dropped onto the lower bogie. Then, the support rollers are returned to a horizontal position, and thereafter, the formed steel sheets are sequentially stacked in the same manner. When the number of stacks reaches a certain number, move the bogie to the side,
After being pulled out to the side of the stacking device, a wire rope is hung on a bundle of formed steel plates and moved to an appropriate position by a crane.

Since the conventional stacking device is as described above, it is necessary to temporarily pull out the formed steel sheets stacked on the trolley to the side of the stacking device, which requires a certain space on the side of the device. was there. In addition, since the above-mentioned stacking device has a fixed length, there is a problem that it is difficult to adapt when the length of the formed steel plate changes.

Therefore, a first object of the present invention is to suspend the formed steel sheets directly from the stacking device by a crane so that the space as in the conventional case is not required,
In addition, it is to have flexibility that can freely correspond to the length of the formed steel sheet.

Further, conventionally, the respective support rollers provided at the tip of the above-mentioned stacking device are simultaneously rotated downward to drop the formed steel sheet downward. For this reason, the formed steel sheets fall in parallel, and the air between the formed steel sheets below does not easily escape, so that the upper formed steel sheet moves on the air and shifts, and there is a problem that the formed steel sheets do not stack orderly.

Therefore, a second object of the present invention is to quickly eliminate the air between the lower formed steel sheet and the formed steel sheet falling above it so that the formed steel sheets are stacked in an orderly manner. is there.

Further, the formed steel sheets stacked in a certain number in the stacking apparatus are bundled as they are and carried to the work site. However, at the work site, they may be divided into small bundles for distribution due to work requirements. It is normal. At this time, in order to divide the bundle into small bundles, it was necessary to lift a predetermined number of pieces to make a gap and pass the rope through the gap, but this work is considerably troublesome.

Therefore, a third object of the present invention is to stack a bundle of formed steel sheets into small bundles that can be easily divided at the work site.

[0011]

[Means for Solving the Problems] Means for solving the above first and second problems is a stopper that abuts the tip of a formed steel sheet at a distance slightly longer than the length of the formed steel sheet in front of the exit of the forming machine. In a stacking apparatus for formed steel sheets, in which a plurality of supporting guide devices are installed at a predetermined interval between the stopper and the outlet of the molding machine, the supporting guide devices are each on an independent substrate. a pair of struts facing on both sides of the passing range of the molded steel sheets are provided, the support arm pivotable on each strut is provided between a first state in which no the support arm into contact with the molded steel plate by the actuator, forming a steel sheet Ru can take a second state for supporting the lower surface of the selective.

[0012] Also, the control device of the actuator of the upper Symbol supporting lifting guide device, when each support arm is returned from the second state to the first state, in order from the closest one or farthest to the molding machine Make sure to return after a time lag .

A means for solving the third problem is that the above-mentioned support guide device has a means for running in the feeding direction of the formed steel sheet.

[0014]

The means for solving the first and second problems are as follows:
When the stacking of the formed steel plates is completed, a rope is hung on the bundle of formed steel plates to set the support arms of each support guide device to the first state, and then the crane is lifted up as it is. The bundle of formed steel plates rises directly between the columns of the respective support guide devices and between the support arms, and is moved to an appropriate position after coming out onto the support guide device.

Further, when stacking the molded steel sheets, molded steel sheet overlaps the molding steel plate downwardly falling obliquely from a state of being supported on the supporting guiding device. For this reason, the air between them is easily removed, and the formed steel sheet that overlaps the upper portion does not move.

According to the means for solving the third problem, the work is temporarily stopped in the middle of stacking, each support guide device is moved slightly forward, and then the work is restarted, so that a predetermined number of sheets are transferred. Stacking can be done for each small bundle of. At the work site, a rope is hung on the misaligned portion and lifted up to make a gap for the rope to be lifted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 to 3, the stacking device according to the first embodiment comprises one stopper 1 and three support guide devices 2.

The stopper 1 is a molding machine 3 (see FIG. 2,
(See FIG. 3), and is installed at a distance slightly longer than the length of the formed steel sheet 4. The structure of this stopper 1 is
An air cylinder 6 and a guide rod 7 are provided on the base 5, and the air cylinder 6 and the guide rod 7 are connected to a contact plate 8 provided on the surface on the molding machine 3 side so that the contact plate 8 can be moved in the front-back direction. I am trying.

The support guide device 2 has the support arm 1 on the upper ends of a pair of left and right columns 11 standing on the base 9.
2 and an air cylinder 13 which is an actuator for operating the support arm 12 thereof. The pair of struts 11 are provided at intervals that are slightly wider than the lateral width of the formed steel plate 4, and the regulation plates 14 in the vertical direction are fixed inside each of the struts 11 at an interval of the lateral width of the formed steel plate 4, and each regulation. The formed steel plates 4 are stacked inside the plate 14.

For details of the support guide device 2, as shown in FIGS. 4 and 5, a support plate 15 parallel to the formed steel plate 4 is fixed to the support 11 by protruding toward the forming machine 3 side. The air cylinder 13 described above is mounted on 15. In addition, a vertical rotating shaft 16 is provided on the column 11 so that a pair of upper and lower bearings 1 is provided.
A rotary shaft 16 is attached to the upper end of the rotary shaft 16, and a shaft head 18 integral with the rotary shaft 16 is provided.

One end of a horizontal link 19 is fixed in the tangential direction of the shaft head 18, and the piston rod 21 of the air cylinder 13 is rotatably connected to the other end of the horizontal link 19 by a pin 22. .

In the middle of the rotary shaft 16, the horizontal support arm 12 is attached to a boss member 23 provided integrally with the rotary shaft 16.

The support arm 12 has the boss member 23.
Roller shaft 25 having one end fixed to the roller shaft 25
The roller 26 and the guide plate 27 are rotatably fitted to the roller 26. The guide plate 27 is arranged along the roller 26, and the roller shaft 25 is provided on both sides of the roller 26.
The guide plate 27 is attached to the rings 28, 28 rotatably attached to the
Both ends of are fixed. Further, a movable guide rod 29 is provided on the ring 28 closer to the support 11 on the side opposite to the guide plate 27.

A fixed guide rod 31 which is in contact with the inside of the movable guide rod 29 in the middle thereof and which horizontally projects toward the other support 11 is fixed to the support 11.

The support guide device 2 is the air cylinder 1.
In the state shown by the solid line in FIG. 5 in which the piston rod 21 of No. 3 is retracted, the support arm 12 is open parallel to the formed steel plate 4, and in this state, it does not contact the formed steel plate 4 (the support arm 12 This state of is called the first state).

In the state shown by the one-dot chain line in FIG. 5 in which the piston rod 21 of the air cylinder 13 has advanced, the support arm 12 is closed at a right angle to the formed steel sheet 4, and in this state the formed steel sheet is The lower surface of the support arm 12 can be supported, and the formed steel plate 4 can slide on the roller 26 (this state of the support arm 12 is referred to as a second state).

During the transition from the first state to the second state, as shown in FIG. 4, the movable guide rod 29 is in contact with the fixed guide rod 31, and the contact point is in the middle of the movable guide rod 29. It gradually inclines while moving from to the top. As a result, the guide plate 27 is gradually lifted, and when the second state is reached, the guide plate 27 is located in front of the roller 26 (on the molding machine 3 side).
At the upper edge of the roller 26,
It is fixed at an angle inclined forward (see the chain line in Fig. 4).

The above three support guide devices 2 have the same structure, but the only difference is the support arm 12
2, the height is closest to the molding machine 4, as shown in FIG. 2, and the height is lower.

The number of support guide devices 2 is appropriately increased or decreased according to the length of the formed steel plate 4.

A control device 32 for controlling the operation of the air cylinder 13 of each of the support guide devices 2 is provided (see FIG. 3).

This control device 32 is provided for each air cylinder 1
3 is operated to move the support arm 12 from the first state to the second state, or vice versa. Further, when the formed steel sheet is supported and released from the second state to the first state, the support guide device 2 closest to the forming machine 3 is opened first, and thereafter, the support guide devices 2 are opened sequentially with a time lag. It has become. Further, the air cylinder 6 of the stopper 1 described above is also controlled by the control device 32.

The apparatus for stacking formed steel sheets of the first embodiment is as described above, and its operation will be described below.

First, the support arm 12 of each support guide device 2
1 is closed from the first state to the second state as indicated by the arrow in FIG. The formed steel plate 4 gradually bends when it is separated from the forming machine 3 due to its flexibility, but it is placed on the inclined guide plate 21 in front of each support guide device 2 and is lifted according to the inclination of the guide plate 27. , On the roller 26.

The forming steel plate 4 advances due to the force received from the forming machine 3, but when the rear end comes off the forming machine 3, the force is not exerted, and thereafter, the rollers 26 of each support guide device 2 are moved.
It moves forward by its own weight or inertia due to the height difference of the stopper 1
Hit the backing plate 8 of.

The stopper 1 is detected by a sensor when the rear end of the molded steel plate 4 is separated from the molding machine 3, and is driven by a signal from the control device 32 based on the detection signal of the sensor.

Further, before the contact plate 8 of the stopper 1 hits the tip of the forming steel plate 4, the air cylinder 13 of the first supporting and guiding device 2 closest to the forming machine 3 is operated and its supporting arm 12 is moved to the first position. The state 2 is released to the first state (see the arrow in FIG. 3). As a result, the rear end of the formed steel sheet 4 begins to fall downward, while the formed steel sheet 4
The front end of the stopper hits the contact plate 8 of the stopper 1 and is retracted (see the alternate long and short dash line in FIG. 2).

The rear end of the retracted formed steel sheet 4 contacts the reference surface 33 below the outlet of the forming machine 3. After the first and second support guide devices 2 are opened to the first state, they are sequentially opened to the first state with a slight time lag. Therefore, the formed steel sheet 4 falls between the regulation plates 14 in a tilted state in which the rear end is low and the front end is high, as shown by the alternate long and short dash line in FIG. 2 (see FIG. 3).

At this time, the air sandwiched between the formerly dropped formed steel sheet 4 escapes in the forward direction in sequence, so that it is quickly discharged. For this reason, no air layer for floating the formed steel plates 4 falling from above is generated, so that the formed steel plates 4 drop straight and pile up orderly.

Further, since the rear end of the formed steel sheet 4 falls while contacting the reference surface 33 of the forming machine 3, the formed steel sheets 4 are also stacked in an orderly manner in the front-rear direction.

When the stacking of a certain number of sheets is completed in this way, the wire rope 34 is hung on the bundle of the formed steel sheets 4, and the crane is lifted just above the support guide device 2 and moved to an appropriate place.

In the first embodiment described above, the stopper 1 is provided with the backing plate 8 which moves in the front-back direction.
The contact plate 8 may be fixed at a position where there can be a predetermined gap between the rear end of the molded steel plate 4 and the molding machine 3 (the cylinder 6 and the guide rod 7 are therefore unnecessary).

The fixed pad plate in this case is formed at a height reaching the floor surface, but the front end can be aligned by dropping the formed steel plate 4 while contacting the fixed pad plate. At this time, the timing of opening the support guide device 2 from the first state to the second state is the earliest when it is close to the fixed contact plate, and thereafter it is sequentially opened with a time lag, and the formed steel plate 3 is dropped in an inclined state. Let However, the support guide device 2 may be opened in order from the molding machine 3 side.

Next, a second embodiment will be described with reference to FIGS. 6 to 9. The basic structure of the stacking device of the second embodiment is the same as that of the first embodiment, but the difference lies in the structure of the support guide device 2.

That is, the support guide device 2 of the second embodiment is also shown in FIG.
And, as shown in FIG. 7, three units are installed. Of these, a partial rail 36 is installed on the floor surface of the central support guide device 2, and a pair of front, rear, left, and right metal attached to the lower surface of the base 5 are installed. Wheels 37 are mounted on the rail 36. Also, the base 5

In addition, an inverted L-shaped movable guide rod 29 is provided on the ring 28 closer to the column 11 so as to project on the side opposite to the guide plate 27.

Bracket 4 to which the motor 52 is attached
In the first state (solid line in FIGS. 8 and 9) in which the fixed guide bar 31 is attached downward to the lower surface of the support arm 12 and the support arm 12 is opened, the movable guide bar 29 slightly moves between the fixed guide bar 31 and the movable guide bar 29. It exists inside it with a gap in between.

Therefore, the movable guide rod 29 contacts the fixed guide rod 31 during the transition of the support arm 12 from the first state to the second state (see the alternate long and short dash line in FIG. 9) by driving the motor 52. Similarly to the case of the first embodiment, the guide plate 27 is gradually lifted, and becomes the inclined state in the second state (see the alternate long and short dash line in FIG. 8).

The support guide device 2 of the second embodiment is as described above. As shown in FIG. 6, three support guide devices 2 are installed between the molding machine 3 and the stopper 1, of which the center is provided. Support guide device 2 has a self-propelled motor 38,
