Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drum can stocker which stacks and stocks drum cans, and when taking them out, sequentially separating them one by one and automatically discharging them.

[0002]

2. Description of the Related Art As one of such drum stockers, the one described in Japanese Patent Laid-Open No. 53-4982 is conventionally known. In this conventional example, a large number of shelves that allow side by side drum cans to be placed side by side in a row are provided in multiple stages, each shelf is inclined at the same angle, and the drum cans automatically roll to the end of each shelf. It is like this.
Then, in order to transfer the drums on each shelf to the crane that moves up and down one by one, and take them out, a pair of stoppers are mounted at the end of each shelf so that they can be retracted, and these stoppers are alternately retracted and retracted to create the most advanced While only one drum can is allowed to roll and is transferred onto 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, but it becomes a large-scale facility and each of the above stoppers is provided. It is necessary to equip each shelf, which is very expensive, and is not suitable as a simple facility in which a relatively small number of drums can be stocked and easily taken out at any time.

By the way, one of the forklifts that stacks and conveys drum cans has laid side-by-side drum cans, each stage is horizontally aligned front and back, and vertically stacked to form a plurality of diagonal stack rows. , There is a type that conveys the shape of a parallelogram that is inclined to one side as a whole, and is currently used in drum can processing plants and the like.

Therefore, the present invention pays attention to this fact, and can relatively easily stock a relatively small number of drums that have been transported in the above-mentioned packing form by a forklift truck while keeping the packing form, and in the stock state. It is an object of the present invention to provide a simple type drum can stocker that can be efficiently taken out one by one.

The drum can stocker according to the present invention is provided with a horizontal lifting platform for loading the drum can, a lifting mechanism for automatically lifting the lifting platform, and a drum can on the lifting platform to maintain a predetermined packing form. Stacking guide, a collapse roll rolling guide for collapsing the stacked drum cans one row at a time to guide rolling forward, and one drum can rolling on the collapse roll rolling guide. And a drum can take-out member for capturing and taking out. The stacking guide has the drum cans laid sideways on the elevating table, the stages are horizontally arranged in front and back, and stacked vertically while being shifted forward and backward to form a plurality of diagonal stacking rows, which are inclined to the rear side as a whole. In order to form a parallelogram-shaped package, it extends rearward and inclines obliquely upward from the rear end of the lifting platform. The load collapse rolling guide is inclined downward from the lower end of the stacking guide and extends forward. The lifting mechanism allows the drum can on the lift table to be placed on the rolling guide and collapsed so that it can be repeatedly transferred to the lift table. Alternate automatically up and down to low position. Since the drum can take-out members are picked up and taken out one by one from the frontmost row of drum cans that collapse and roll forward on the load collapse rolling guides, they repeatedly rotate at the front end position of the load collapse rolling guides.

[0007] It is preferable to provide a seat portion for restricting the rolling of the lowermost drum in each stack row on the lift table. In addition, since the drums transferred on the load collapse rolling guide are sequentially collapsed from the front row, the stoppers that regulate the forward rolling of the drum cans at the bottom of each stacking row are set so that the action position and rolling that can regulate the rolling It is desirable to be provided so as to be able to repeatedly move to and from the allowed retracted position. The drum can take-out member has a concave portion and a regulating portion capable of capturing only one drum can, and is repeatedly rotated by an actuator between a first rotation position and a second rotation position to make a first rotation. At the position, the drum can rolling on the load collapse rolling guide is received by the recess, and at the second rotation position, the drum can is discharged from the recess forward,
The regulation part can regulate the forward rolling of the following drum can.

[0008]

[Operation] When a drum can that has been transported by the forklift in the above-mentioned packing form is transferred from the forklift onto the lifting platform, the transferred drum can is stocked on the lifting platform while maintaining the same packing form as on the forklift. To be done. When the lifting platform lowers the load by the lifting mechanism and lowers it to a lower position lower than the rolling guide, the drum can in the front row at that time collapses the load and collapses on the rolling guide, and the one at the bottom first rolls the load. It rolls on the guide and is received by the drum can take-out member. Since the drum can take-out member repeatedly rotates, one received drum can is captured and taken out, and at the same time, the succeeding drum can is prevented from collapsing and rolling on the rolling guide. Then, by repeating the operation by such a drum can take-out member and the raising and lowering of the lifting platform,
The stacked drum cans are sequentially collapsed from the front row, collapsed on the rolling guides, and taken out one by one by the drum can extraction 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, since the drum can 1 is carried into the drum can stocker by a forklift (not shown) in the same packing form as shown in FIG. 1, the state of FIG. Is the front side, but when the drum can 1 is taken out from the drum can stocker, the direction of arrow A (right side in FIG. 1) is the take-out direction.
This drum can stocker has this A direction as the front. Therefore, Fig. 1 shows the left side of the drum stocker, Fig. 2 shows the front,
FIG. 3 shows the respective planes.

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

At the intermediate position of the frame 2, a horizontal elevating table 9 which is long in the front and rear direction is mounted so as to be vertically movable within a predetermined height range. The lifting platform 9 is composed of two parallel steel bars 10 on the left and right, and a seat portion 11 for preventing the drum can 1 from rolling forward and backward is provided on the upper surface thereof at a predetermined interval in the front and rear direction in the example shown in the figure. It is provided at four locations. As shown in FIG. 4, a pair of guide plates 12 are vertically provided on the lower surface of the platform 9 to guide the vertical movement of the platform 9, and the frame 2 is sandwiched between the guide plates 12 to guide the vertical sliding. The guide member 13 is fixed.

Further, a load collapsing rolling guide 15 is fixedly installed at an intermediate position of the frame 2, and a stacking guide 16 which continuously inclines from the rear end of the load collapsing rolling guide 15 of the frame 2. It is fixedly installed at the rear.

The load collapsing rolling guide 15 is constructed by arranging two left and right rods 17 on the frame 2 in a direction parallel to the left and right outside of the two shaped steels 10 of the lifting platform 9, and these two shaped steels. 10 has a drum can transfer portion 15a that extends forward while gently inclining downward, and an extension portion 15b that extends forward with a slight increase in inclination angle from a position beyond the front end of these mold steels 10.

The stacking guide 16 includes two bar members 1 on the left and right.
8 is continuously connected to the left and right two bar members 17 of the load collapse rolling guide 15 and is raised diagonally rearward from the rear end of the frame 2
It is fixedly erected on and extends rearward and obliquely upward from the rear end of the lift 9.

In order to automatically and repeatedly raise and lower the lift table 9 to the two high and low positions, the following lift mechanism is attached to the frame 2 below it. That is, as shown in FIGS. 4 and 6, front and rear two shafts 20 are respectively supported between the left and right intermediate beam members 19 of the frame 2, and the left and right arms 21 and links 22 are fixed to the respective shafts 20. ing. The upper ends of the left and right arms 21 are pin-connected to the lower surfaces of the left and right shaped steels 10 of the lifting table 9, and the lower ends of the front and rear links 22 are connected by a turnbuckle 23. The turnbuckle 23 is connected to a piston rod 25 of an elevating air cylinder 24 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 simultaneously watch or counterclockwise. By rotating in the direction, the elevating table 9 can be elevated and lowered to a higher position and a lower position lower than the drum can transfer portion 15a of the rolling guide 15 while maintaining the horizontal state.
1, 4 and 6 show the state in which the lift 9 is in the high position, and FIGS. 5 and 7 show the state in the low position. When the lift table 9 is lowered to the lower position, the drum can 1 is lifted on the lift table 9
When the cargo cans are transferred onto the drum can transfer portion 15a of the crushing rolling guide 15 and the elevating table 9 is raised to the high position again, the drum cans 1 are again mounted on the elevating table 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 rotatable 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 supported between the front ends of the intermediate beam members 19 of the frame 2, and extending the left and right sides of the load collapse rolling guide 15. It is located between the parts 15b. A link 29 is fixed to the shaft 27. Since the 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 in the clockwise or counterclockwise direction ( It is rotated forward or backward). The two plates 28 of the drum can take-out member 26 are formed with arcuate recesses 28a corresponding to the outer circumference of the drums 28 to capture the drum can 1. The arcuate rear ends of the plates 28 are collapsed and rolled. Motion guide 1
5 is a restricting portion 28b that restricts the forward rolling of the drum 1 on the left and right extended portions 15b of the drum 5.

Further, a front guide 32 is pivotally mounted above the drum can take-out member 26 at the front end portion of the frame 2 so as to be rotated back and forth by the expansion and contraction of the piston rod 34 of the air cylinder 33. This front guide 32
Is to prevent the frontmost drums 1 on the lift table 9 from collapsing unintentionally. Normally, the drum cans 1 are tilted rearward as shown in FIGS. 1, 4 and 5. When the drum can 1 is loaded onto the lift table 9 by the forklift, it is rotated forward and retracted.

Further, a stopper 35 is arranged between the seat portions 11 of the lift table 9. This stopper 35
As shown in FIG. 5, when the lift table 9 is lowered to the low position and the drum cans 1 on the lift table 9 are collapsed and transferred onto the drum can mounting portion 15a of the rolling guide 15, they are transferred one row at a time. It is for breaking down, and is composed of, for example, an air cylinder. When the piston rod of the stopper 35 protrudes above the drum can mounting portion 15a, the stopper 35 restricts the drum can 1 from rolling forward of the protruding position and retracts below the drum can mounting portion 15a. In this case, the drum can 1 is allowed to roll on the drum can mounting portion 15a.

Next, the operation of the drum stocker thus constructed will be described. When carrying the drum 1 into this drum can stocker by a forklift,
As shown in FIGS. 1 and 4, the elevating table 9 is raised to a high position and the front guide 32 is retracted forward. The drums 1 loaded on the lift table 9 by the forklift in the packing form as shown in FIG.
Extends rearward obliquely upward from the rear end of the lifting table 9, so that it can be placed and stocked on the lifting table 9 while maintaining the same packaging as the forklift.

By operating the lifting air cylinder 24, the lifting table 9 is lowered from the state shown in FIGS. 1 and 4 to a low position as shown in FIG. 5, and the drum can 1 is collapsed to roll the rolling guide 15.
When it is transferred onto the drum can mounting portion 15a, first, the one drum can 1 at the bottom of the front row is rolled from the drum can mounting portion 15a to the extension portion 15b and received by the recess 28a of the drum can removing member 26. . At this time, the drum cans 1 in the other rows except the front row maintain the current state because the lowermost drum cans 1 in each row are prevented from rolling forward by the stopper 35. From 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 can 1 received by the concave portion 28a is captured by the drum can take-out member 26 and is moved forward as shown in FIG. At the same time, the second drum 1 in the front row
The extension portion 1 is formed by the regulating portion 28b of the drum can take-out member 26.
Rolling to 5b is restricted. In addition, the drum can take-out member 2
One drum can 1 discharged by 6 is sent to, for example, a drum can reversing device (not shown), and is automatically inverted from the horizontal posture to the vertical posture.

When the drum can take-out member 26 is rotated backward and then again forward, the second drum can 1 in the front row is captured and discharged, and at the same time, the third drum can 1 in the front row is removed. , The regulating portion 28b of the drum can take-out member 26
The rolling of the extension member 15b is restricted by the rotation of the extension member 15b. When the drum can take-out member 26 is repeatedly rotated back and forth again, the third drum can 1 is discharged.

When the discharge of one row of drum cans 1 is completed in this way, the frontmost stopper 35 withdraws downwards, causing the next row of drum cans 1 to collapse, and the bottom one canister first. Drum can 1 collapses and rolls forward on the drum can mounting portion 15a of the rolling guide 15 to move the drum can removing member 2
It is received by the concave portion 28a of No. 6 and is captured by this and discharged. By repeating the same operation thereafter, the drum cans 1 are sequentially collapsed one row at a time, collapsing on the rolling guides 15, and discharged one by one by the drum can extraction member 26.

[0023]

The drum can stocker of the present invention has the following effects. Since it can be stocked as it is in a predetermined loading form carried by a forklift, that is, as a parallelogram shape that is inclined to the rear as a whole, it is easy to carry in and it is offered as a simple drum can stocker at low cost. it can. By repeatedly raising and lowering the lifting platform, the drums that are stacked diagonally are sequentially collapsed one row at a time from the front side, collapsed on the rolling guide and rolled forward, and captured by the drum can take-out member Since they are taken out one by one, they can be taken out one by one efficiently.

By providing a seat portion for restricting the rolling of the drum can on the lift table, the drum can can be stocked in a stable state. By providing a stopper that regulates the forward rolling of the drum cans at the bottom of the stacking row, and by making this stopper repetitively movable between an action position where rolling can be regulated and a retracted position that allows rolling, the drum cans are It is possible to prevent the drums in the other rows from being accidentally collapsed when taken out. If the drum cans are picked up and taken out one by one by the drum can take-out member and the subsequent drum cans are regulated by the drum can take-out member, the mechanism for taking out the drum cans can be simplified.
