Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article storage device used for entering and exiting articles such as round bars, storage or in a garage of a vehicle, and more particularly, to an article storage device mounted on a multi-tiered support bracket. The present invention relates to an article storage device that selectively pulls out a plurality of article storage pallets and conveys the article storage pallet to an article loading / unloading position at a predetermined height.

[Problems to be solved by the invention]

In order to efficiently use limited space in factories and warehouses and to improve work efficiency, it is extremely important to store materials and the like in an organized manner, and various storage means have been considered. Although a storage having multi-stage storage shelves is used, it is difficult to put in and take out when the height is out of reach, and heavy objects such as round steel are particularly dangerous.

Therefore, a storage device has been developed in which a lifting stage is provided in front of the multi-stage storage, and a storage pallet at a desired position is placed on the lifting stage and moved up and down to a storage position at a predetermined height. There is an inconvenience that the storage pallet needs manual labor to put in and out, and the space in front of the storage is always occupied by the elevating stage, so that it cannot be used as a passage or the like.

Therefore, a main object of the present invention is to transport a desired storage pallet accommodated in a casing of a storage device to a work position of a predetermined height by a consistent electric operation by a pallet transportation member that moves horizontally and vertically. Another object of the present invention is to provide a multi-stage article storage device in which a pallet transport member is stored in the storage device when it is unnecessary, and does not occupy the space in front of the storage device.

Further, another object of the present invention is that the opening of the storage housing is closed with a shutter as the pallet transport member descends,
Another object of the present invention is to provide the multi-stage article storage device provided with a shutter mechanism that opens and closes a shutter above and below a conveying member by a predetermined vertical width in conjunction with expansion and contraction of the conveying member at a desired pallet position.

[Means for solving the problem]

The main object of the present invention is to provide a storage housing in which a plurality of upper and lower pallet support brackets are provided inside a frame having a pallet access opening on one side, and mounted on each support bracket of the storage housing. An article storage pallet that is housed so as to be able to be taken in and out through an access opening and a base member that is vertically movable along the side surface of the support bracket group inside the storage housing, and that is capable of carrying the article storage pallet. A pallet transport member having an arm member capable of extending and contracting in the horizontal direction; a telescopic drive mechanism for extending and retracting the telescopic arm member of the pallet transport member; and a vertical drive mechanism for vertically moving the pallet transport member. This can be achieved by a characteristic multi-stage article storage device.

Preferably, the telescopic arm member of the pallet transport member includes a distal telescopic arm engaged with the base member so as to be extendable and contractible in a horizontal direction, and a telescopic arm between the distal telescopic arm member and the engaging portion of the base member. The pallet transport member is configured with a mounted intermediate arm,
A pair of sprockets attached to the front and rear sides of the distal extensible arm, at least one of which is rotated forward and reverse by a driving device attached to the distal extensible arm, and wound back between the pair of sprockets, and both ends are integrated with the base member. With the chain belt fixed to the bracket, the tip extendable arm and the guide rail of the base member are rolled on the upper and lower surfaces of the engaging roller axially attached to the intermediate arm, so that the distal extendable arm engages with the intermediate arm. The roller is configured to extend and contract while rolling with respect to the base member.

In addition, the telescopic drive mechanism of the pallet transport member includes a pair of sprockets, which are rotated forward and reverse by a driving device having at least one of them mounted on the distal arm, on both front and rear sides of the distal telescopic arm, and wound between the pair of sprockets. The two ends of the chain belt are fixed to a bracket integral with the base member, and the vertical drive mechanism of the pallet transport member uses the pull-up chain belt and the pull-down chain belt fixed to the base member as a shared forward / reverse drive sprocket. It is desirable to have an engaged configuration.

Another object of the present invention is to mount the shutter for closing the pallet access opening of the storage housing upward so as to open upward and freely movable up and down on the multi-stage article storage device. The lowering wire for closing is engaged or engaged with the telescopic arm member of the transport member, and the opening above the transport member is automatically closed by the shutter in conjunction with the shortening of the telescopic arm. This can be achieved by providing a shutter mechanism that automatically opens the shutter above the conveying member by a predetermined width in conjunction with the extension of the arm.

The conveying member controls the motors of the telescopic drive mechanism and the vertical drive mechanism using an encoder or a proximity switch, etc., so that a desired palette is automatically pulled out and stored by a series of electric operations. .

[Function of the invention]

The pallet transport member is configured such that the telescopic arm portion carrying the pallet expands and contracts automatically and self-propelledly, and the whole moves up and down electrically, so that the arm portion is extended and moved up and down to a desired pallet position of the storage housing. The arm is extended while the part is shortened and the pallet is slightly lifted,
When the transport member is moved up and down to a predetermined work position, the article storage pallet stored in the storage housing is automatically transferred to the predetermined work position, and the article can be loaded and unloaded. The pallet is stored in its original position in the housing by the reverse operation. In the position where the pallet is completely stored, the transport member is always in a state where the arm portion is shortened, and is therefore stored in the storage housing. At the end of the operation, the transport member may be stored in a predetermined location in the housing.

The telescopic arm member of the transport member is self-propelled by a pair of sprockets, one of which is a driving side, and a chain belt wound around these sprockets and having one or both sides fixed to a base member.

An intermediate arm is interposed between the distal extensible arm with the chain belt engaged and the engaging portion of the base member, and the upper and lower surfaces of the rotating roller pivotally mounted on the intermediate arm are rolled into contact with the distal extensible arm and the guide rail of the base member. When supported, the stroke of the telescopic arm can be kept long and stable. At this time, the moving speed of the distal extensible arm and the intermediate arm is 2: 1 and moves synchronously with respect to the base member.

When the shutter mechanism is provided in the article storage device of the present invention, the entire opening of the storage housing is closed when the transport member is stored in the lowermost predetermined storage section,
At an arbitrary position, the shutter above the conveying member opens by a predetermined vertical width in conjunction with the extension of the arm, and closes in conjunction with the shortening of the arm.

(Example of the invention)

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, the storage housing 1 is formed of a frame having a predetermined width, depth and height.
A pallet access opening 2 is formed at the front (in the figure), and a horizontal pallet support bracket 4 is integrally provided in a plurality of stages vertically from the support 3 located at the rear of the storage housing 1 toward the opening 2 inside. Have been.

Each palette support bracket 4 of the storage housing 1
Is composed of a pair of left and right members in the embodiment of the figure, and article storage pallets 5a, 5b, 5c.
It is housed so that it can be taken in and out through the access opening 2.

Reference numeral 6 denotes a housing opening 2 which carries a desired pallet 5 housed on a support bracket 4 in the housing 1.
1 is a pallet conveying member which is carried forward and is moved up and down to a working position at a predetermined height along the housing 1. The pallet conveying member 6 is provided at a front portion of the housing 1 as shown in FIGS. It comprises a horizontally long base member 9 that moves up and down along a guide rail 8 of an upright guide column 7 and a telescopic arm member 10 that expands and contracts in the horizontal direction along the longitudinal direction of the base member 9.

As shown in FIGS. 3 and 4, the base member 9 of the transport member 6 is disposed inside the housing 1 so as to move up and down along the side surface of the support bracket group. The fixed upper, lower, left and right four engaging rollers 11a, 11b and 11c, 11d are combined with the left and right guide rails 8,
8 so as to be movable in the vertical direction of the storage housing along the column 7.

The telescopic arm member 10 of the pallet transport member 6 may be composed of only the tip arm member 10a,
As shown in FIG. 6 to FIG. 6, it is constituted by a distal end telescopic arm 10a and an intermediate arm 10b for reinforcing the engagement of the distal end telescopic arm 10a with the base member 9. In this case, an intermediate arm 10b is movably interposed between the engagement portion of the distal extensible arm 10a and the base member 9, and the upper and lower portions of the plurality of engaging rollers 12 axially attached to the intermediate arm 10b are connected to the distal extensible arm 10a. The guide rails 10a 'and 9' of the base buzzer 9 are rolled, so that the distal extensible arm 10a and the intermediate arm 10b are
It moves at a speed of one to one. Further, the distal end telescopic arm 10a integrally has a supporting bracket 13 extending outward, and supports the distal end of the pallet 5 locked to the supporting bracket 4 of the housing 1 from below.

As shown in FIGS. 3 to 7, a telescopic drive mechanism that expands and contracts the telescopic arm member 10 with respect to the base member 9 includes a pair of the distal end arms 10a that are rotated in the longitudinal direction, that is, at least one of the front and rear sides by a driving force. Sprockets 14a, 14
b facing each other and this sprocket 14
A chain belt 15 is wound between a and 14b and both ends thereof are fixed to a bracket 16 integrated with the base member 9. On the contrary, the sprocket is attached to the base member 9.
14a and 14b may be attached, and a bracket 16 may be provided on the telescopic arm to fix the chain between the sprockets.

In the illustrated embodiment, the conveying member 6 is connected to the columns 7, 7 of the housing 1.
The left and right telescopic arms 10a, 10a of the transport members 6, 6 are connected by a hollow crosspiece 17 to form an integral member.

Further, as shown in the figure, a rotating shaft 18 extending over the entire length of the hollow connecting crosspiece 17 is installed inside the hollow connecting crosspiece 17, and one end of each of the pair of telescopic arms 10a, 10a is fixed to each of the sprockets 14a, 14a, and connected. A motor 19 is integrally provided in the middle of the crosspiece 17, and the motor 19 rotates the rotating shaft 18 via a gear and a chain (or a combination of bevel gears).

Thus, when the drive-side sprocket 14a of the distal extensible arm 10a is rotated by the rotating shaft 18, the chain belt 15 is pulled to one side, so that the distal extensible arm 10a extends or shortens (by reverse rotation) with respect to the base member 9 in a self-propelled manner. . At this time, since the intermediate arm 10b is in rolling contact with the distal extensible arm 10a and the base member 9 via the roller 12, the intermediate arm 10b expands and contracts with the distal extensible arm 10a at half the speed thereof.

The vertical drive mechanism of the transport member 6 includes a pull-up chain belt 20a fixed to the base member 9 and a pull-down chain belt 20b.
Guide sprockets 21 and 22 mounted above and below support 7
Through a common drive sprocket 23 that rotates forward and backward through the drive sprocket.

In the embodiment of FIG. 1, the pull-up chain belt 20a of one base member 9 of the pair of left and right base members 9, 9 is connected as a pull-down chain belt 20b of the other base member 9 ', as shown in FIG. The thus formed two-system operation chain belt is connected to a common drive sprocket 23 driven by a motor and a speed reducer (not shown).
Are engaged so that they are sent in opposite directions to each other.

Although not shown in the figure, the pull-up chain belt 20a and the pull-down chain belt 20b of one base member 9 are wound around upper and lower guide sprockets and connected endlessly.
The working chain belt of each base member thus formed may be engaged in a reverse drive on the double drive sprocket.

The lower guide sprockets 22, 22 are actually mounted coaxially.

Thus, the transport member 6 is normally stored in the lowermost stage inside the storage housing 1 with the telescopic arm member 10 contracted,
After extending the telescopic arm member 10 if necessary, the base member 9 is moved up and down along the columns 7, 7
It is transported up and down.

Accordingly, the motors of the telescopic drive mechanism and the vertical drive mechanism of the transport member 6 can be sequence-controlled in the following order.

(1) Extend the telescopic arm member.

(2) Move the base member up and down to a pallet position at a predetermined step. (3) Shorten the telescopic arm member.

(4) Slightly raise the base member to carry the pallet.

(5) Extend the telescopic arm member.

(6) The base member is moved up and down to a work position at a predetermined height.

By the above operation, the pallet 4 at the predetermined stage is automatically conveyed to the predetermined work position, and the pallet 4 and the conveying member 6 are contracted to the predetermined position in the storage housing 1 by the reverse operation. Such automatic control can be easily achieved by motor control by a proximity switch or an encoder.

In the embodiment shown in FIG.
A shutter mechanism that opens and closes by a vertical movement of the base member 9 and opens and closes by a predetermined width by expansion and contraction of the telescopic arm member 10.

That is, the pallet access opening 2 of the storage housing 1
A shutter 24 is stretched openably and closably. The shutter 24 extends to the rear of the housing via upper guide rollers 25 and 26, and is urged by a weight 27 suspended from the rear end to open the opening 2 upward.

On the other hand, as shown in FIG.
A wire 29 for pulling down the shutter 24 downward is connected to 28, and this wire 29 is wound around a stationary wheel 30 which is pivotally mounted on the distal end side of the base member 9 as shown in FIG. Further, it is wound around a movable pulley 31 attached to the intermediate arm 10b of the telescopic arm member 10, and its tip is fixed to the base member 9 (stopper 33 in the figure).

Accordingly, since the intermediate arm 10b is pulled down as it is extended and the wire 29 is loosened, the shutter 24 is opened upward by a predetermined width by the weight 27, and as the intermediate arm 10b is shortened, the pull-down wire 2 is pulled down.
The opening above the conveying member 6 is closed to pull 9 downward.

By adjusting the distance between the moving pulley 31 and the fixed pulley 30 or the stopper 33, the predetermined opening / closing width can be changed. Reference numeral 32 denotes a rod which can be displaced in the lateral direction and is fixed to the intermediate arm 10b. The moving pulley is fixed to the tip of the rod 32.

When the transport member 6 itself is moved up and down, the shutter 24 is moved.
Is moved along by the weight and the pull-down wire 29. Therefore, when the transport member 6 is raised to the uppermost stage, the access opening 2 is fully opened, and when the transport member 6 is lowered to the lowermost stage, the entire chain is formed.

In the embodiment shown in the drawings, the apparatus for storing and transporting the pallet 4 has been exemplified. However, by appropriately designing the strength of the supporting columns, support brackets, chains, motors, and other members, the apparatus can be applied to a multi-stage garage. Although the embodiment in which the transport member 6 is provided on both the left and right sides has been described, the present invention is not limited to this.
This also includes a configuration in which the carrying bracket of the distal extensible arm 10a is elongated in the lateral direction to form the cantilevered conveying member 6.

〔The invention's effect〕

According to the present invention, the pallet conveying member moves in the vertical direction of the storage housing and expands and contracts in front of the opening, so that the pallet of an arbitrary stage is conveyed to a work position of a predetermined height. Can be stored in the housing. Therefore, the conveyance member does not become an obstacle, and the front of the storage housing can be used effectively.

Since both the vertical movement and the expansion and contraction operation of the transport member are driven by a motor or the like, the removal and storage of the pallet can be completely automated. In particular, since the telescopic arm member of the transport member has a built-in motor for driving and expands and contracts in a self-propelled manner, there is no need to provide a pallet access mechanism at each stage.

Furthermore, when the shutter is not needed, the entire shutter opening is closed, and the necessary part is opened only when needed, so that there is no waste, and since this operation depends on the operation of the telescopic arm, a special No drive is required. Also, since the shutter is connected to the base of the conveying member via a wire and urged upward, a part of its weight can be offset with the urging force of the shutter when the pallet moves up and down. It is.
