Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reversing piling device for picking up products conveyed on a conveying conveyor in a lateral direction of the conveyor which is perpendicular to the conveying direction of the conveying conveyor and stacking them alternately or in reverse order. Regarding,
In particular, for products such as flat deck plates used as concrete formwork during concrete floor construction, products that have a flat upper surface and multiple longitudinal ribs on the lower side with a space in the product width direction, In addition, the present invention relates to an inversion piling device suitable for stacking work including products in which a part including one or both ribs in the product width direction is cut off.

[0002]

2. Description of the Related Art As shown in FIG. 6, deck plates (so-called flat deck plates) having a cross-sectional shape having one side flat and a plurality of longitudinal ribs provided on the other side at intervals in the product width direction are stacked. In the case of piling), simply stacking the products as they are will result in a stacking height that is twice as high as the product height, significantly increasing the product space, occupying a large inventory space, and increasing the packing volume. It is required to stack and reduce the stack height. For this reason, in a deck plate manufacturing line for manufacturing a deck plate by cold roll forming, an inversion piling device is provided for alternately inverting and stacking products conveyed on a runout table of a forming equipment. As will be described later, FIG. 6 shows an example of width cutting of the flat deck plate, and the symbol S is a standard product without width cutting.

As a conventional reversing piling device of this type, there is one in which a reversing device 6 shown in FIG. 9 is provided at the position of a runout table. The reversing device 6 has an annular frame 4 to which holding rollers 2 and 3 for sandwiching a product (deck plate) 1 vertically are attached, and a drive gear 5 meshing with a gear 4a formed on the outer periphery of the annular frame 4 is provided. The drive gear 5 allows the annular frame 4 to be 180 ° for each product.
The product 1 is rotated one by one, and every other product 1 is turned upside down. When the reversing device 6 is used, as shown in FIG. 10, the product 1 molded by the molding machine 7, cut by the cutting machine 8 to a fixed length, and conveyed by the runout table 9 is transferred by the reversing device 6 as described above. Every other piece is turned over, and then conveyed forward and stacked by the piling device 10.

Further, as shown in FIG. 11, an angle θ larger than 90 ° is provided in the middle of a horizontal feed conveyor for laterally feeding the product 1.
The first arm 11 rotatable by ₁ and (180 ° -θ
Second arm 1 that can rotate by an angle θ ₂ similar to ₁ )
And 2 is provided to rotate the product 1 in the first arm 11 by an angle theta _1, the waiting in the angle theta ₂ happened posture 2
There is also one in which a reversing device 13 for tilting the product 1 to the arm 12 side for delivery and then reversing the product 1 with the second arm 12 horizontal is used.

[0005]

In the method using the reversing device 6 shown in FIG. 9, the reversing operation is carried out in the annular frame 4, so that the products shown in FIG.
As shown in 0, it has to be transported further forward,
There is a problem that the total length of the line becomes long.

Further, in the method using the reversing device 13 shown in FIG. 11, when the product 1 is transferred from the first arm 11 to the second arm 12, the product 1 and the second arm 12 are caused to fall over. The collision noise becomes a loud noise. Further, this reversing device 13 must be provided in the middle of the lateral feed conveyor that feeds the cut-out products 1 in the lateral direction perpendicular to the conveying direction of the run-out table, and in order to perform the reversal stacking, the reversing device 13 must be reversed. Since a stacking device is required in addition to the device 13, there is also a problem that the space of the equipment occupies a large amount.

Further, since the processing speed of each of the reversing devices 6 and 13 is not always high, there is a problem that when the time cycle of the product conveyed on the runout table is short, it may not be possible to follow this. ..

By the way, depending on the beam span laying the deck plates (beam span in the width direction of the deck plate), there may be a surplus in the width dimension of the deck plate of the terminal. In this case, one side of the deck plate in the width direction or A so-called width-cutting process of cutting off parts on both sides may be performed. It is conceivable that this width cutting is performed in the deck plate manufacturing line, but in that case, there arises a problem in the packaging packing form (outline of the binding section). As shown in FIG. 6 described above, there are four types of width-cut products A, B, C, which are standard products S that are not width-cut and width-cut products that are narrowed.
The case of stacking together with D will be described as an example. Especially, in FIG. 6, the rib at the left end is cut off.
There is a problem with stacking type of width-cut products. That is, looking at the superposition of one set of normal and reverse postures, the width for one set is almost the same as shown in FIGS. 8C and 8D for combinations other than the D type. Although it is constant, in the combination including the D type, there is a case in which the width for one set becomes short as shown in FIGS. 8A and 8B. In addition, since there is no rib at the end between the D types, it becomes unstable with respect to one set of forward and reverse stacking. For this reason, if the D-type width-cut products are stacked in the same manner as the standard product S or the other width-cut products A, B, and C, the outline is entirely as shown in FIGS. 8A and 8B. It becomes uneven and becomes unstable when it is tightened and tied with the binding hoop, or the cantilevered edge of the product is easily deformed. However, since the above-described conventional reversing devices 13 and 16 simply reverse the product, it is difficult to make the above-mentioned packing packing form stable and free from product deformation.

The present invention has been made in order to solve the above-mentioned conventional drawbacks. It is less noisy, and the reversing and stacking can be performed by the same device, so that the space can be saved, and it can be transported. Inverting piling device that can easily cope with extremely short time cycles of incoming products and, when stacking so-called width-cut products, provides a stable and unpacked packaging form without fear of product deformation. The purpose is to provide.

[0010]

A lower arm that is movable and can move up and down, a lower arm lateral drive mechanism that drives the lower arm by a certain distance in the lateral direction of the conveyor, and a parallel direction with the lower arm that is provided at a lateral position of the conveyor. Axis, a reversing arm rotatable by 180 ° about the axis, and the reversing arm 180 degrees around the axis.
A rotary drive mechanism that rotates and a suction device that is attached to the reversing arm and that can suck the product on the transfer conveyor are provided. In the above,
The term "stacking products by inverting them alternately or in any order" means that the products are stacked one after another, such as front and back or front and back.

[0011]

[Operation] In the above configuration, the operation of stacking the products as they are on the roller conveyor (normal stacking operation)
Is performed by lowering the upper arm, sucking the product by the suction device, moving it in the lateral direction of the conveyor, lowering it, and then releasing the suction. The operation of reversing and stacking the products (reversing and stacking operation) is performed by raising the reversing arm together with the lower arm and the shaft from under the conveyor to adsorb and hold the product by the suction device, and then rotating the reversing arm by 180 °. Is reversed and adsorption is canceled. During the normal stacking operation, the reversing arm can wait for the next product to be immediately adsorbed, and during the reversing stacking operation, the upper arm can wait for the next product to be adsorbed immediately, and products can be sent one after another in a short time cycle. Even if you come, you can easily respond.

Among the width-cut products, if the stacking position is laterally shifted and the packing load is appropriate, in the case of the normal stacking operation, before the lowering of the upper arm,
The second lateral drive mechanism moves the upper arm in the lateral direction of the conveyor by a certain distance, and the position of the adsorption device on the upper arm side during the adsorption operation is displaced in the lateral direction of the conveyor by a certain distance. Also, in the case of reverse stacking operation, before raising the lower arm,
The lower arm lateral drive mechanism moves the lower arm in the lateral direction of the conveyor by a certain distance, and the position of the adsorption device on the lower arm side during the adsorption operation is displaced in the lateral direction of the conveyor by a certain distance.
As a result, it is possible to perform stacking in which only specific width-cut products are laterally shifted so as to form a stable packaged product in which product deformation does not occur.

Although not shown, like the electromagnet 56 on the upper arm 27 side, a touch switch (touch SW) that turns on when the electromagnet 82 rises and comes into contact with the product 1 on the roller conveyor 20. Is provided.

Next, the operation will be described. Now, the standard product S shown in FIG. 6 and four kinds of width-cut products A, B, C,
Stacking in which D is mixed is performed. The operation of stacking the products 1 sent on the roller conveyor 20 on the transverse feed conveyor 22 in a posture in which they are not turned upside down, that is, the normal stacking operation is performed except for a specific width cut product, for example, the above-mentioned D type width cut product. And, if there is no particular problem with the time cycle in which the product 1 is transported,
Basically, it is performed according to the procedure of steps (S1) to (S12) shown in the flowchart of FIG. That is, (S1) the sent product 1 is stopped at a predetermined position on the roller conveyor 20. (S2) The chain 51 is circulated by the lifting drive motor 45, the upper lift table 24 connected to the chain 51 is lowered, and the upper arm 27 is lowered together with the upper lift table 24. (S3) The electromagnet 56 is the product 1 on the roller conveyor 20.
When touched, the touch SW is turned on and the touch of the product 1 is detected. (S4) The electromagnet 56 is excited by the touch SW ON signal, and the product 1 is attracted. (S5) The elevating drive motor 45 operates, the chain 51 circulates, and the upper arm 27 moves up together with the upper elevating table 24. (S6) The chain 32 is driven by the drive drive motor 31.
And the pinions 33 and 34 rotate, and the upper arm 2 passes through the rack 35 that meshes with the pinions 33 and 34.
7 is fed (advanced) in the lateral direction of the conveyor indicated by the arrow a in FIG. (S7) The upper arm 27 stops, and the electromagnet 56 that suspends the product 1 stops at a fixed position (immediately above the product stacking position on the transverse feed conveyor 22). (S8) The chain 51 orbits and the upper arm 27 descends. (S9) When the product 1 adsorbed by the electromagnet 56 is placed on the transverse feed conveyor 22 or the product 1 previously placed, the touch SW is turned on. (S10) The electromagnet 56 is demagnetized by the touch SW ON signal, and the product 1 is released. (S11) The upper arm 27 rises as the chain 51 orbits. (S12) The upper arm 27 is driven by the pinions 33 and 34 via the rack 35 to retract, and returns to the initial state in FIG. According to the above procedure, the normal stacking operation of stacking the products 1 on the roller conveyor 20 in the same posture on the transverse feed conveyor 22 is performed.

The above procedure is for the case where the product is long and the time cycle for sending the product is relatively long, but when the time cycle is short, it is shown in the flowchart of FIG. Follow the procedure. That is, when the upper arm 27 is raised and lowered, the air cylinders 58 and 59 are actuated in parallel with the raising and lowering of the upper arm 27 so that the piston rods 58a and 59b are retracted and raised and lowered (raised and pulled down) of the chains 60 and 61. Then, the electromagnet 56 suspended by the chains 60 and 61 is moved up and down. In this way, the up-and-down time of the electromagnet 56 supporting the product 1 is shortened, and a short time cycle is dealt with. In the flowchart of FIG. 4B, the upper arm 27 moves up and down (S2, S5, S8, S1).
1) and the lifting and lowering operations of the chains 60 and 61 (S2 ', S
5 ′, S8 ′, S11 ′, etc.) are performed in parallel. However, if necessary, the lifting and lowering of the chains 60 and 61 may be omitted when only the lifting and lowering of the upper arm 27 is required, or the lifting and lowering of the upper arm 27 may be omitted when the lifting and lowering of the chains 60 and 61 is sufficient. Good.

When the products 1 on the roller conveyor 20 are turned upside down and stacked on the transverse feed conveyor 22, that is, the reverse stacking operation is performed, the flow chart shown in FIG. The procedure is performed from step (P1) to step (P12). That is, (P1) the sent product 1 stops at a predetermined position on the roller conveyor 20. (P2) The lower arm 40 rises, and the reversing arm 81 and the electromagnet 82 integrated with the lower arm 40 rise together with the lower arm 40. At this time, the reversing arm 81 and the electromagnet 82 are horizontally positioned below the roller conveyor 20. When the lower arm 40 is lifted, the chain 51 is rotated by the lifting drive motor 45 to raise the upper lift table 24, and the lower lift table 2 connected to the upper lift table 24 via the connecting rod 26.
5 is raised together with the upper lift table 24. Although not shown in this embodiment, an air cylinder or the like for independently raising and lowering the lower elevating table 25 may be provided so that the lower arm 40 can be quickly moved up and down. (P3) When the reversing arm 81 moves up together with the lower arm 40 and the electromagnet 82 comes into contact with the lower surface of the product 1, a touch SW (not shown) detects this and turns on. (P4) The electromagnet 82 is excited by the touch SW ON signal, and the product 1 is attracted. (P5) The lower arm 40 and the reversing arm 81 continue to rise. The lower arm 40 is raised by raising the lower lift table 25 together with the upper lift table 24, as in the case of the above-described lowering. (P6) The reversing drive motor 83 drives the shaft 80 and the reversing arm 81 integrated with the shaft 80 to rotate 180 ° in the counterclockwise direction (direction of arrow c) in FIG. 1. As a result, the product 1 is attracted to the lower surface of the electromagnet 82 in a posture in which it is turned upside down. (P7) The lower arm 40 and the reversing arm 81 descend. (P8) When the product 1 attracted by the electromagnet 82 rides on the product 1 placed earlier, the touch SW is turned on. (P9) The electromagnet 82 is demagnetized by the touch SW ON signal, and the product 1 is released. As described above, the product 1 is stacked on the previous product 1 in a posture in which the product 1 is turned upside down. (P10) The lower arm 40 moves up to the initial height position. (P11) The reversing arm 81 is rotated clockwise (arrow d direction) by an angle of a little less than 90 ° (this operation is called semi-reversal). The lower arm 81 is in a semi-inverted posture in which it is substantially vertical as shown by the chain double-dashed line.
Wait to be lifted from the roller conveyor 20 by the side electromagnet 56. (P12) When the next product 1 is lifted from the roller conveyor 20 by the electromagnet 56, the reversing arm 81 immediately further rotates clockwise (direction of arrow d) in FIG. It returns to the initial state (state shown by the solid line) of standing by in a horizontal posture below.

In the above, the normal stacking operation by the upper arm 27 and the reversing stacking operation by the reversing arm 81 have been individually described, but both of them are performed in parallel in order to shorten the time cycle.

Next, the operation when the D-type width-cut product is sent will be described. At the time of normal stacking, in the flow chart shown in FIG. 1 (a) or (b), the upper arm lateral movement air cylinder 36 is operated before the product is stopped (step S1), and the upper arm 27 is shown for a certain distance of the cylinder stroke. In 1 move to the right. If the operation shown in the flowchart of FIG. 4 (a) or (b) is performed in this state, the position of the electromagnet 56 at the time of product adsorption is displaced to the right by a certain distance. When stopped at the same fixed position and lowered, the D type products are stacked at a position shifted to the left by a fixed distance.

Further, when the D-type width-cut product is sent during the reverse stacking, the lower arm lateral movement air cylinder 44 is activated before the product stop (step P1) in the flowchart of FIG. , The lower arm 40 is moved to the right in FIG. 1 by a certain distance of the cylinder stroke. In this case, the position of the electromagnet 82 when the product is adsorbed shifts to the right by a certain distance. Therefore, after the product is adsorbed and lifted, the lower arm lateral movement air cylinder 44 is returned to move the shaft 80 together with the lower arm 40 normally. When the reversing arm 81 is then reversed like any other product, the D type product is reversed and stacked at a position displaced to the right by a certain distance.

When only the D type is laterally shifted and stacked as described above, instead of the stacked packing form of FIG. 8 described above, as shown in FIGS. The D-type products in the posture are shifted to the left by a certain distance, and the inverted D-type products are shifted to the right by a certain distance in the stacking.
In addition, the ribs are appropriately arranged when the front and back of the D types are superposed one on the other, and a stable packaged product with no fear of product deformation can be obtained.

The inversion piling device of the present invention can also be applied as an inversion depiling device in which the front and back are taken out one by one from a product group in which the front and back are inverted alternately or in any order. .. Also,
This inversion depiling device can also be used, for example, when some processing is performed on a once-piled product.

Further, although the roller conveyor is used as the transfer conveyor in the embodiment, the present invention is not limited to this, and may be, for example, a belt type conveyor divided into a plurality of parts. In short, it is sufficient if the reversing arm 81 has a space where the reversing arm 81 can move up and down at the position of the conveyor.

Further, in the above-mentioned embodiment, the inversion piling device is installed in the run-out table part of the cold roll forming equipment, but not limited to this case, the inversion piling device (or the inversion depiling device) in various equipments ) Is applicable.

[0029]

According to the present invention, the front and back of the product can be removed by the take-out operation by the suction device provided on the upper arm of the transfer conveyor and the take-out operation by the suction device provided on the reversing arm below the transfer conveyor. Since the stack is configured to be alternately or inverted in any order, the time loss can be reduced as much as possible, and the stacking operation can be performed extremely efficiently. Further, since the product is held by adsorption, the collision noise of the product is small and the noise is reduced.

The structure is such that products are inverted and stacked by one device, and space can be saved as compared with the conventional system in which the reversing device and the stacking device are separately provided. In addition, since the product is directly taken out from the conveyor and is subjected to the inversion piling, unlike the conventional method using the inversion device having the annular frame, it is not necessary to convey the product further forward from the inversion operation position. However, space can be saved. Further, unlike the conventional method using the reversing device having the first and second arms, a lateral feeding conveyor for laterally feeding the product from the feeding conveyor is not necessary, and in this respect, space saving can be achieved.

Since a second lateral drive mechanism for moving the upper arm in the lateral direction of the conveyor by a constant distance and a lower arm lateral drive mechanism for moving the lower arm in the lateral direction of the conveyor by a certain distance are provided, only a specific width-cut product is provided. It is possible to move the machine in the lateral direction of the conveyor to make it a stable packaged product without the risk of product deformation.

On the side of the upper arm, a second lateral drive mechanism for moving the conveyor laterally by a predetermined distance is provided separately from the first lateral drive mechanism for moving the normal conveyor lateral direction. The control for laterally moving only the cut product is simplified, and the system design is simplified.
