Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a sheet-like plate stacking apparatus for piling the end faces of sheet-like plates and stacking the plates in an aligned manner.

(Prior Art) Conventionally, there is an apparatus shown in FIG. 5 that piles sheet materials and laminates them in an aligned manner.
In FIG. 5, a rootstock 52 is placed on a lift table 51, and a sheet-like plate material W is laminated on this rootstock 52. The sheet-shaped plate materials W are transferred onto the lift table 51 from another conveyance device in a misaligned manner, but when conveying the sheet-shaped plate materials W to the next process, they are conveyed in an aligned and stacked state. There are times when you have to. Therefore, the end faces of the sheet-like materials W that have been stacked inconsistently are stamped using a pair of side guides 53 and piled to stack the sheet-like materials W in an aligned manner. 51
Since there is a gap between the bottom edge of the side guide 53 and the bottom edge of the side guide 53, a problem arises in that the sheet material W gets caught in this gap during stamping. To avoid this problem, conventionally,
Stamping is performed while the lower surface of the sheet-like plate material W is held at a position slightly higher than the lower edge of the side guide 53 by the rootstock 52. In the figure, 54 is an air cylinder for stamping, the rod end of which is fixed to the side guide 53.

(Problem) However, in the conventional device as described above, a rootstock 52 is required, but this rootstock 52 is not only unnecessary during transportation, but also must be removed when promoting automation in the next process. There were many cases where this was not the case, and how to deal with it became a problem.

(Means for Solving the Problems) The present invention has been devised in view of the above-mentioned conventional problems, and is a method for laminating sheet-like boards that does not require a rootstock and does not cause the board to be caught during piling. The purpose of the present invention is to provide a device, the gist of which is that a pair of movable frames 6, 6 that can be moved to appropriate positions according to the dimensions of the sheet material W are arranged on a lift table 1 that can be moved up and down, A pair of side guides 2, 2 are disposed on each movable frame 6, 6 so as to be repeatedly movable via an air cylinder 3, and the sheet-like plate material W is piled with the pair of side guides 2, 2, and the lift table 1, a pedestal 4 is installed in the gap between the lower edge of the side guide 2 and the lift table 1 at least on the side guide 2.
This pedestal 4 has a link bar 29 that rotates the pedestal 4 downward under its own weight, and an air cylinder 18 that is connected to the outside of the link bar 29. Arms 22 and 26 are connected to each other, and the arms 22 and 26 rotate and pull out the pedestal 4 to the outside of the side guide 2 when the pedestal 4 starts piling the side guide 2.
is held at a position slightly higher than the lower edge of the side guide 2, and after a certain amount of sheet material W has been piled, as the lift table 1 descends, it rotates downward via the link bar 29, and the arm 22 and 26 so as to be actively retracted to the outside of the side guide 2.

(Function) A pedestal is interposed in the gap between the lower edge of the side guide and the lift table, and this pedestal can hold the sheet material at a slightly higher position than the lower edge of the side guide when piling the side guide starts. This prevents the sheet material from being caught in the gap between the lower edge of the side guide and the lift table. In addition, after a certain amount of sheet material has been piled, the pedestal can be rotated downward via the link bar as the lift table descends, and the arm can be pulled out to the outside of the side guide. Sheet materials stacked in a consistent manner without rootstocks are placed on the holder, and can be transported to the next process.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

First, to explain the outline of this embodiment with reference to FIG. 1, sheet materials W (iron plates, plywood, resin plates, etc.) are loaded one by one onto the top surface of a lift table 1 that can move up and down from a separate loading device. Laminated.
In order to stack the loaded plate materials W in an aligned manner, two side guides 2 are disposed oppositely on the lift table. That is, the side guides 2, 2 are repeatedly moved by air cylinders 3, 3, and the end faces of the stacked plates are intermittently stamped and piled by the repeated movements of the two side guides 2, 2. , the plate materials W are stacked on the lift table 1 in an aligned manner. During this time, the pedestals 4, 4 are inserted into the gaps between the lower edge of each side guide 2, 2 and the lift table 1, and the receiving surfaces 4a, 4a of the pedestals 4, 4 are on the inside of the side guide 2.
It is held at a position slightly higher than the lower edge of the side guide 2. Therefore, the receiving surfaces 4a, 4a of the cradle come into contact with the lower surface of the lowermost plate W, and hold the lowermost plate W at a position higher than the lower edge of the side guide 2. Therefore, when piling by the side guides 2, 2, the trouble that the lowermost plate material W gets caught in the gap between the lower edge of the side guides 2 and the lift table 1 does not occur. Furthermore, after the piling is completed, the supports 4, 4 are moved down by the moving means to the outside of the side guides 2, 2 while being lowered with the lowering of the lift table 1. 1 and transported to the next process. Next, when a new lift table is transferred below the side guides 2, 2, the pedestal 4 is returned to its original position,
The lowermost plate material W is held in a position higher than the lower edge of the side guide 2 by interposing it in the gap between the lower edge of the side guide 2 and the lift table 1.

Note that when the stacking height of the sheet materials W is set high, the lift table 1 is lowered after a certain amount of sheet materials W have been piled, and the pedestal 4 is accordingly lowered and moved by the moving means. It is retracted to the outside of the side guides 2, 2.
Therefore, with the plate material W placed directly on the lift table 1, the lift table 1 is further lowered, and the sheet-like plate materials are successively piled toward the upper layer and stacked in a high-rise layer.

Hereinafter, each part of the laminating apparatus of this example which performs the above operation will be explained based on FIGS. 2 to 4.

FIG. 2 shows a partially cutaway plan view of the laminating device of this example, and FIG. 3 is a partially cutaway detailed view of section C in FIG.
The figure shows a view taken along the line DD in FIG. 3.

In FIG. 2, reference numeral 5 denotes a pair of fixed frames arranged symmetrically on the left and right sides of the figure, supported by legs 5a and 5a, respectively, and set at a height corresponding to the lift table 1. It is arranged. In the figure, reference numerals 6, 6 indicate a pair of movable frames installed between the fixed frames 5, 5, which are installed symmetrically above and below in the figure, respectively. Both ends of the pair of movable frames 6, 6 are screwed 6a into threaded rods 7, 8 disposed on the left and right fixed frames 5, 5, respectively. Therefore, as the threaded rods 7, 8 rotate, the movable frames 6, 6 can move on the fixed frames 5, 5 in the vertical direction in the drawing. That is, the threaded rod 7 has a right-hand thread, and the threaded rod 8 has a left-hand thread, so the double-threaded rods 7 and 8
When the movable frames 6, 6 are connected and rotated in the same direction, the pair of movable frames 6, 6 move toward or away from each other. Reference numeral 9 in the figure is a bearing for the threaded rods 7 and 8, and reference numeral 10 in the figure is a coupling that connects the threaded rods 7 and 8. Incidentally, the rotational force of the threaded rods 7 and 8 is transmitted via a bevel gear 12 by a reduction motor 11 disposed at the lower right end in the figure, and is further transmitted to the left side via a shaft 13 and a gear 14. Next, the side guide 2 disposed inside the movable frames 6, 6 will be explained.

Side guides 2, 2 are arranged inside the upper and lower movable frames 6, 6, respectively, and these side guides 2, 2 are connected to each movable frame 6, 6 by a guide bar 15 and an air cylinder 3. They are connected so that they can be moved repeatedly. That is, as shown in FIGS. 1 and 2, the cylinder portion of the air cylinder 3 is fixed to the movable frame 6, and the rod end of the air cylinder 3 is fixed to the side guide 2. Further, the end of the guide bar 15 is fixed to the side guide 2, and the housing 16 supporting the guide bar 15 is connected to the movable frame 6.
It is fixedly installed. Therefore, by introducing air into the air cylinder 3 fixed on the movable frame 6 side, the rod of the air cylinder 3 moves in and out, and the side guide 2 fixed on the end of the rod moves repeatedly with respect to the movable frame 6. Will have to move. In this case, the guide bar 15 fixed to the side guide 2 slides inside the housing 16 fixed to the movable frame 6 while being guided by the housing 16, so the side guide 2 is stable with respect to the movable frame 6. make repetitive movements. Moreover, since an appropriate number of air cylinders 3 and guide bars 15 are provided along the movable frame 6, the repeated movement of the side guide 2 with respect to the movable frame 6 becomes more stable. Incidentally, the side guide 2 is formed in a cross-sectional shape, and is erected so that the upper part thereof expands outward.

Next, a cradle 4 arranged below the side guide 2
and its means of transportation will be explained.

The pedestal 4 is formed in the shape of a horizontally long plate, and its cross-sectional shape includes a receiving surface 4a at the top, a recessed portion 4b at the rear of the receiving surface 4a, and a tapered portion 4c at the front of the receiving surface 4a. . And the receiving surface 4a is the fourth
In the figure, the lowermost plate W stacked on the lift table 1 comes into contact with the lower surface of the lowermost plate W to hold the lowermost plate W at a position slightly higher than the lower edge of the side guide 2. In that case, the recess 4b is located below the lower edge of the side guide 2. This recess 4b
Piling is performed by repeatedly moving the lower edge of the side guide 2 inside.

In FIGS. 2, 3, and 4, an air cylinder 18 is fixed to the outside of each movable frame 6 via a bracket 17.
The rod 19 of this air cylinder 18 extends along the movable frame via a nut 20 and a connecting rod 21, and is connected to the nut 2 arranged at equal intervals.
0, the upper arm 22 is rotatably attached to the pin 2.
It is pinned in 3. The end of the upper arm 22 is fixed to a shaft 25 inserted through a bearing 24 fixed to the movable frame 6. A dogleg-shaped lower arm 26 is fixed to the lower end of the shaft 25, and a bracket 27 is rotatably pinned to this lower arm 26. This bracket 2
7 is connected via two link bars 29 to a fixed bracket 28 fixed to the rear upper part of the pedestal 4. Note that the ends of the link bar 29 are rotatably pinned with pins 30, respectively. Therefore, the pedestal 4 can be rotated downward together with the fixed bracket 28 via the link bar 29 as shown in FIG. Moreover, by operating the air cylinder 18, the rod 1
9, the upper arm 22 is rotated, and the upper arm 2
2 rotates the lower arm 26, and the lower arm 26 moves the bracket 27 rearward.
Therefore, by the operation of the air cylinder 18, the pedestal 4 can also be moved rearward (to the outside of the side guide 2) with respect to the side guide 2, and the lift table 1, which is in contact with the lower surface of the pedestal 4, is lowered. The pedestal 4 is rotated downward by its own weight and is also moved rearward by the operation of the air cylinder 18.

According to the stacking apparatus of the present embodiment, the pair of movable frames 6, 6 are moved to appropriate positions by operating the deceleration motor 11 in advance according to the dimensions of the sheet-like plates W to be stacked on the lift table 1. After that, the plate materials W are placed on the lift table 1 and stacked. Piling of the plate material W is performed by repeatedly moving the side guide 2 by operating the air cylinder 3, and repeatedly pinching the plate material W by the pair of side guides 2, 2. During this piling work, the plate material W with the receiving surface 4a of the pedestal 4 located at the lowest end
The lowermost plate W is held in a slightly higher position than the lower edge of the side guide 2 by contacting the lower surface of the side guide 2, and the plate W
is prevented from being pinched between the lower edge of the side guide 2 and the lift table 1. Thereafter, after the piling is completed and the end faces of the plate materials W are aligned, the lift table 1 is lowered, and the pedestal 4 is accordingly lowered by rotation of the link bar 29. As the pedestal 4 descends, the air cylinder 18 is activated, and its operating force is transmitted to the rod 19, knuckle 20, upper arm 22, lower arm 26, bracket 27, link bar 29, bracket 28, and pedestal 4.
The pedestal 4 is pulled out to the outside of the side guide 2. Therefore, the plate material W is directly placed on the lift table 1 and transported to the next process. or,
As described above, when the stacking height of the sheet materials W is high, even after the pedestal 4 is pulled out, the lift table 1 is not conveyed and continues to descend one by one, and the pile of sheet materials W gradually moves toward the upper layer. Continued. In that case, the lift table 1 has already been lowered, so there is no need to worry about the sheet material W getting caught.

Note that a conveyor may be provided on the upper surface of the lift table 1 to convey the continuously piled plate material W to the next process.

In this way, according to the laminating apparatus of this example, since the pedestal 4 is brought into contact with the lower surface of the plate material W at the start of piling, there is no need for a rootstock as in the conventional method, and the plate material W after piling is transferred to the next process. This has the advantage that conveyance can be carried out smoothly and the entire apparatus can be automated.

(Effects) According to the present invention, a pair of movable frames that can be moved to appropriate positions according to the dimensions of the sheet material W are arranged on the lift table 1 that is movable up and down, and an air cylinder is attached to each movable frame. A pair of side guides 2, 2 are arranged so as to be repeatedly movable through the lift table 1, and the sheet-shaped plates W are piled by the pair of side guides 2, 2, and the sheet-shaped plates W are stacked on the lift table 1 in an aligned manner. In this device, a pedestal 4 is interposed between the lower edge of the side guide 2 and the lift table 1, leaving at least a gap between the lower edge of the side guide 2 and the lower edge of the side guide 2. A link bar 29 that rotates the pedestal 4 downward under its own weight, and an arm 22 connected to the outside of the link bar 29 and rotated by the operation of the air cylinder 18 to pull out the pedestal 4 to the outside of the side guide 2. .
is held at a position slightly higher than the lower edge of the side guide 2, and after a certain amount of sheet material W has been piled, as the lift table 1 descends, it rotates downward via the link bar 29, and the arm By configuring the structure so that the rotation of the side guides 22 and 26 actively retracts the side guides 2 to the outside, it is possible to prevent the sheet material from being caught in the gap between the lower edge of the side guide and the lift table at the start of piling. No trouble occurred,
Moreover, after a certain amount of sheet material has been piled, the pedestal can be rotated downward via the link bar as the lift table descends, and the arm can be pulled out to the outside of the side guide. It has the advantage that it can be stacked in a consistent manner on the lift table without a rootstock.
