DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drum stocker in which drums are stacked and stocked, and when they are taken out, they are separated one by one and automatically discharged.

[0002]

2. Description of the Related Art As one of such drum can stockers, for example, one described in Japanese Patent Application Laid-Open No. 53-4982 is conventionally known. In this conventional example, a number of shelves on which drums laid side by side can be placed in a row are provided in multiple stages, each shelf is inclined at the same angle, and the drum can automatically rolls to the end of each shelf. It has become.
Then, in order to transfer the drums on each shelf one by one to an ascending and descending crane one by one and take them out, a pair of stoppers are attached to the end of each shelf so that they can come and go, and these stoppers are made to come and go alternately. While only one drum can is allowed to roll and rolled on the crane, the following drum can is restricted from rolling by a stopper protruding from the upper surface of the shelf.

[0003]

However, according to this, since a large number of shelves are provided in multiple stages, a large number of drums can be stocked. It is necessary to equip each shelf, which is very expensive, and is not suitable for a simple facility that can stock a relatively small number of drums and easily take them out at any time.

On one side of a forklift for stacking and transporting drums, horizontal drums are arranged horizontally in front and rear of each stage, and are stacked vertically while being shifted back and forth to form a plurality of oblique stacked rows. There is a type in which the whole is transported in the form of a parallelogram inclined to one side, and is currently used in a drum can processing plant or the like.

In view of the above, the present invention is capable of easily stocking a relatively small number of drum cans, which have been conveyed in the form of a forklift as described above, in the form of the form, and the stock state. An object of the present invention is to provide a simple drum can stocker that can be efficiently taken out one by one.

[0006]

According to the present invention, a plurality of diagonally stacked rows are formed by laying drums sideways, each stage being horizontally arranged back and forth, and vertically being shifted back and forth.
A drum can stocker that reloads and stocks drums from a forklift that has been transported in a parallelogram-shaped package inclined to one side as a whole, and removes them one by one from the front row in order to remove them. And the following means. A horizontal elevator 9 on which the drum 1 is placed. An inclined stacking guide 16 extending rearward diagonally upward from the rear end of the elevator 9 so that the drum 1 from the forklift is placed on the elevator 9 in the same package as on the forklift. This stacking guide 16
Load collapse rolling guides 15 extending downward from the lower end of the vehicle. In order to reload the drum 1 on the lifting platform 9 onto the unloading rolling guide 15 and reload it repeatedly on the lifting platform 9, the lifting platform 9 is moved to the unloading rolling guide 15.
A lifting mechanism that automatically raises and lowers alternately between a higher position and a lower position. In order to restrict the forward rolling of the lowermost drum can 1 of each stacking row on the elevating platform 9 and to sequentially break the drum cans 1 loaded on the unloading rolling guide 15 from the front row, the rolling can be restricted. A plurality of stoppers 35 that can be repeatedly moved between a position and a retracted position that allows rolling. In order to capture and take out one drum can 1 at a time from the frontmost drum can 1 which collapses and rolls forward on the unloading rolling guide 15, it has a concave portion 28a and a regulating portion 28b capable of capturing only one drum can 1, and an actuator. The drum can 1 is repeatedly rotated between the first rotation position and the second rotation position, and in the first rotation position, the drum 1 that has rolled on the unloading rolling guide 15 is received by the concave portion 28a. In the second rotation position, the drum can take-out member 26 that discharges the drum 1 from the recessed portion 28a forward and regulates the forward rolling of the subsequent drum can by the regulating portion 28b.

[0007] A seat 11 for restricting the rolling of the lowermost drum 1 of each stacking row is preferably provided on the lift 9.

[0008]

[Function] When a drum can conveyed by a forklift in the above-mentioned form is transferred from the forklift to the elevating platform, the transferred drum can is stocked on the elevating platform while maintaining the same form as the forklift. Is done. When the elevator is lowered by the lifting mechanism and lowered to a lower position than the rolling guide, the drum in the front row at that time collapses and collapses on the rolling guide. It rolls on the guide and is received by the drum take-out member. Since the drum can take-out member rotates repeatedly, it catches and takes out one received drum can and at the same time restricts the following drum can from unloading and rolling on the rolling guide. And by repeating the operation by such a drum can take-out member and the raising and lowering of the elevator,
The stacked drums are sequentially collapsed from the front row and collapsed on the rolling guides, and are taken out one by one by a drum take-out member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. In FIG. 1, the drum can 1 is loaded into the drum stocker by a forklift (not shown) in the packing state shown in FIG. 1 toward the paper of FIG. 1, so that the state of FIG. Is the front, but when taking out the drum 1 from the present drum can stocker, the direction of arrow A (the right side in FIG. 1) becomes the taking-out direction.
In this drum stocker, the direction A is defined as the front. Therefore, FIG. 1 is the left side of the drum stocker, FIG.
FIG. 3 shows the respective planes.

As shown in these figures, the present drum can stocker has a plate-shaped door 6 suspended by wires 5 from front and rear pulleys 4 supported on the upper ends of front and rear columns 3 on the left side of a frame 2. This door 6 is connected to a wire 5 by a piston rod 7
The door can be opened and closed by operating a door opening and closing air cylinder 8 connected to the drum can. When the drum 1 is loaded into the drum stocker by a forklift, the door 6 is lowered as shown in FIGS. And keep it open.

At a middle position of the frame 2, a long vertical elevator 9 which is long in the front and rear directions is mounted so as to be able to ascend and descend within a predetermined height range. The elevating table 9 is formed of two parallel left and right shaped steel bars 10, and a seat 11 for preventing rolling of the drum 1 back and forth is provided on the upper surface thereof at predetermined intervals in the front and rear in the example shown in FIG. It is provided in four places. As shown in FIG. 4, a pair of guide plates 12 are vertically provided on the lower surface of the frame to guide the elevating table 9 up and down. Guide member 13 is fixed.

In addition, a load unloading rolling guide 15 is fixedly installed at an intermediate position of the frame 2, and a stacking guide 16 that is continuously inclined from the rear end of the load unloading rolling guide 15 is provided with a stacking guide 16. It is fixedly installed at the rear.

The unloading rolling guide 15 comprises two right and left bars 17 which are laid on the frame 2 in parallel to the left and right outside of the two steel bars 10 of the elevator 9. It has a drum can transfer portion 15a that extends forward while gently inclining downwardly along 10, and an extension portion 15b that extends a little further from the position beyond the front end of these steel bars 10 to extend forward.

The stacking guide 16 includes two right and left bar members 1.
8 is continued to the two bar members 17 on the left and right sides of the unloading rolling guide 15 and is raised diagonally backward from the rear end to
And extends obliquely upward and rearward from the rear end of the elevating table 9.

In order to automatically and repeatedly raise and lower the elevating table 9 to two elevations, the following elevating mechanism is mounted on the frame 2 below the elevating table 9. That is, as shown in FIGS. 4 and 6, two front and rear shafts 20 are respectively supported between the left and right intermediate beams 19 of the frame 2, and the left and right arms 21 and the links 22 are fixed to the respective shafts 20. ing. The upper ends of the left and right arms 21 are respectively pin-connected to the lower surfaces of the left and right mold steels 10 of the elevator 9, and the lower ends of the front and rear links 22 are connected by turnbuckles 23. The turnbuckle 23 is connected to a piston rod 25 of an air cylinder 24 for elevating and lowering, which is pivotally attached to the rear end of the frame 2. When the piston rod 25 expands and contracts, the front and rear two sets of arms 21 are simultaneously clockwise or counterclockwise. The lift 9 is lifted to a higher position and a lower position higher than the drum transfer portion 15a of the rolling guide 15 while maintaining the horizontal state.
FIGS. 1, 4 and 6 show a state where the elevator 9 is at a high position, and FIGS. 5 and 7 show a state where it is at a low position. When the elevator 9 descends to the low position, the drum 1 moves to the elevator 9
When the lift 9 is raised again to a high position, the drum 1 is again placed on the lift 9.

A drum can take-out member 26 for taking out the drums 1 one by one is pivotally attached to the front end of the frame 2 so as to be able to rotate back and forth. That is, the drum can take-out member 26 is formed by fixing two left and right plates 28 to a shaft 27 that is supported between the front ends of the intermediate beams 19 of the frame 2. It is located between the parts 15b. A link 29 is fixed to the shaft 27. Since this link 29 is connected to the piston rod 31 of the drum can take-out air cylinder 30 pivotally attached to the front end of the frame 2, when the piston rod 31 expands and contracts, the drum can take-out member 26 moves clockwise or counterclockwise ( (Forward or backward). The two plates 28 of the drum can take-out member 26 are formed with arc-shaped concave portions 28a corresponding to the outer periphery of the drum 28 for capturing the drum 1, and the arc-shaped rear ends of these plates 28 are unloaded. Motion guide 1
5 is a regulating portion 28b that regulates the forward rolling of the drum 1 on the left and right extension portions 15b.

Further, a front guide 32 is pivotally mounted at the front end of the frame 2 above the drum can take-out member 26 so as to be rotated back and forth by expansion and contraction of a piston rod 34 of an air cylinder 33. This front guide 32
Is to prevent the drum 1 in the front row, especially on the elevator 9 from crumbled, and is usually in a state of being slanted rearward as shown in FIGS. 1, 4 and 5. When the drum 1 is carried into the elevator 9 by a forklift, it is turned forward and retracted.

A stopper 35 is disposed between the seats 11 of the lift 9. This stopper 35
When the elevator 9 descends to the lower position as shown in FIG. 5 and the drum 1 on the elevator 9 collapses and is transferred onto the drum rest 15 a of the rolling guide 15, the drums 1 are moved one by one. It is for breaking down, and is composed of, for example, an air cylinder. When the piston rod protrudes above the drum can mounting portion 15a, each stopper 35 regulates the rolling of the drum 1 forward from the protruding position, and retracts below the drum can mounting portion 15a. In such a case, the rolling of the drum 1 on the drum mounting portion 15a is permitted.

Next, the operation of the thus constructed drum stocker will be described. When the drum 1 is carried into the drum stocker by a forklift,
The elevator 9 is raised to a high position as shown in FIGS. 1 and 4, and the front guide 32 is retracted forward. The drum 1 transported by the forklift onto the lift 9 in the form shown in FIG.
Extend obliquely upward and rearward from the rear end of the lift 9 and are placed and stocked on the lift 9 while maintaining the same package as on the forklift.

The operation of the lifting air cylinder 24 lowers the lifting platform 9 from the state shown in FIGS. 1 and 4 to a low position as shown in FIG.
When the drum 1 is transferred onto the drum mounting portion 15a, the lowermost drum 1 in the front row first rolls from the drum mounting portion 15a to the extended portion 15b and is received by the concave portion 28a of the drum can removing member 26. . At this time, the drum cans 1 in the other rows except the front row maintain their current state because the lowermost drum can 1 in each row is restricted from rolling forward by the stopper 35. In this state, when the drum can take-out member 26 is rotated forward by the operation of the drum can take-out air cylinder 30, one drum 1 received by the concave portion 28a is caught by the drum can 1, and as shown in FIG. And at the same time, the second drum 1 in the front row is
The extension portion 1 is controlled by the regulating portion 28b of the drum can take-out member 26.
Rolling to 5b is regulated. In addition, the drum can take-out member 2
One drum 1 discharged by 6 is sent to, for example, a drum reversing device (not shown) and is automatically reversed from a horizontal posture to a vertical posture.

When the drum take-out member 26 is rotated backward and then forward again, the second drum 1 in the front row is captured and discharged, and at the same time, the third drum 1 in the front row is discharged. Of the drum can take-out member 26
The rolling to the extension 15b is regulated by the above, and when the drum can take-out member 26 is repeatedly rotated back and forth again, the third drum 1 is discharged.

When the discharge of the drums 1 for one row has been completed in this way, the drum 35 in the next row collapses because the stopper 35 on the foremost side is retracted downward, and the lowermost one of the drums 1 is first removed. Of the drum can 1 collapses and rolls forward on the drum mounting portion 15a of the rolling guide 15, and the drum can take-out member 2
6 is received by the concave portion 28a, and is caught and discharged by the concave portion 28a. By repeating the same operation, the drum cans 1 are sequentially collapsed one by one and collapsed on the rolling guides 15, and are discharged one by one by the drum can take-out member 26.

[0023]

According to the drum stocker of the present invention, the following effects can be obtained. It can be stocked as it is in the specified package loaded by a forklift, that is, in the form of a parallelogram inclined to the rear as a whole, so it is easy to carry in and provided at a low cost as a simple drum stocker it can. By repeatedly raising and lowering the lifting table, the drums stacked diagonally are sequentially unloaded one by one from the front side, collapsed on the rolling guides, rolled forward, and captured by the drum can take-out member. Since it is taken out one by one, it can be taken out one by one efficiently.

A stopper is provided for regulating the forward rolling of the lowermost drum in the stacking row, and this stopper can be repeatedly moved between an operation position where the rolling can be restricted and a retracted position where the rolling is allowed. In addition, when taking out the drums, it is possible to prevent the drums in other rows from being accidentally collapsed. Since the drum can is taken out and taken out one by one by the drum can take-out member, and the subsequent drum can is regulated by the drum can take-out member, the mechanism for taking out the drum can can be simplified. If a seat for restricting the rolling of the drum can is provided on the elevator, the drum can be stably stocked.
