Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a multilayer storage device for storing items of the same size and shape, such as returnable plastic boxes for beer, juice, etc., and cardboard boxes. Equipped with a clipping device that can be moved up and down (while gripped) and traveling, and a lifting fork that can lower the cargo to the receiving floor directly below the clipping device, it is possible to store cargo in multiple layers without requiring any shelves for storage. The present invention relates to an autostereoscopic storage device that can be stacked in rows.

Various types of multi-storey warehouses are used to store cargo three-dimensionally, but all of them are large and require a large amount of equipment cost. Like a cardboard case,
When containers and boxes of a certain size are frequently taken in and out, operating costs are higher than expected, which poses a practical problem.

For this reason, the present applicant has previously proposed Patent No. 870502 (
In Japanese Patent Publication No. 51-35751), there is a storage frame in which a number of storage spaces in which luggage can be stacked in multiple layers are arranged adjacent to each other in the horizontal direction, and a storage frame is provided near the lower end of each storage space to hang the left and right sides of the luggage within the storage space. A claw support device that can be opened and closed, a traverser that is located below the storage frame and can move in the lateral direction of the storage space, and a traverser that has a length that spans the entire length of the storage space and is mounted so that it can be raised and lowered on the traverser. We have invented and disclosed a multi-stage stacking type storage device consisting of an accumulation type conveyor device. However, in the above-mentioned patent, the stored items are advanced to the lower part of a predetermined storage frame by an accumulation conveyor, the conveyor is pushed up by a lift cylinder, and the conveyor is stopped by a hook in the storage space, and the next stage of items is loaded. When lifting, the items in the storage space are pushed up together with the items in the upper tier, and the items in the lowest tier are stacked one after another with the items hooked to the hooks.Also, a conveyor is advanced under the storage frame, and the items are supported by the hooks while being raised. The system opens the device, transfers the cargo at the bottom to the conveyor, returns to the lowered position, and then launches the cargo on the conveyor to be loaded, so it is a large-scale system that creates a large number of storage spaces. The installation of storage frames is essential. Furthermore, a conveyor supported by a lift cylinder on a traverser for pushing up cargo into a storage space is patented, and a claw support device must be provided for each storage frame, which not only makes the entire equipment complex and expensive, but also makes it difficult to operate. Management is also not as good as in a multi-storey warehouse.
However, there were inconveniences such as the need to maintain fairly strict control. In view of the above points, the present invention completely eliminates the need for racks and storage frames for stacking luggage, and uses a system in which a slat-shaped pedestal is arranged on the floor of the stacking space and stacked directly on it. This simplifies the entire device by stacking the containers one after another on top of the lower cargo without pushing them up from below, making operation management much easier.

The cargo handled is boxes and containers of a certain size and shape, such as plastic cases and cardboard boxes.The example below shows the case where plastic cases used as returnable beer bottles are stacked and loaded. Ta.

Next, embodiments of the present invention will be described with reference to the drawings. Fig. 1 is a plan view of the entire device, Fig. 2 is a front view, and Fig. 3 is a side view, the main parts of which are a gutter-type storage device body 1 that runs on rails installed on the floor; A storage conveyor 8 provided along the longitudinal direction of the storage device main body, a clipping device 31 for gripping the luggage stored in a line on the storage conveyor, and a clipping device 31 for supporting the luggage gripped by the clipping device from below.

As shown in FIGS. 2 and 3, the wheels 6, 6 are connected to a driving electric motor 2, a transmission shaft 4, and a transmission mechanism 3 using gears or chains.
The device main body 1 is rotated by the rail 16 to run in forward and reverse directions along the rail 16. As will be described later, a slat-shaped case stand 10 is arranged on the floor between the rails 16, 16. The space surrounded by the frames 13, 14 and the beam 15 serves as a storage space for the case 9, as shown in FIG. A relay conveyor 17 that can be operated in forward and reverse directions is installed parallel to one of the rails 16, and the cases sent by the relay conveyor 17 are sent to the storage conveyor 8 via the driven corner roller conveyor 7, or It will be operated so that cases loaded and unloaded from No. 8 are transferred and discharged. [Storage Conveyor] The storage conveyor 8 is a drive roller conveyor or an accumulation rate type conveyor, and operates in forward and reverse directions, and stores a predetermined number of cases 9 in a row using stoppers 11 and 12 near both ends.

This storage conveyor 8 is mounted on a frame 18 that extends horizontally from approximately the center of the frames 13 and 14 of the main body 1 of the apparatus as shown in FIGS. A corner conveyor 7 is attached.

The case 9 can be loaded and shipped at any position, and it goes without saying that forward and reverse operation is possible. 1st
In the case of Figures 1 to 3, the storage conveyor 8 is provided on a framework 18 extending from the storage device main body 1, and the drive corner conveyor 7 is also attached integrally with the storage conveyor. The conveyor 8 may be separated from the storage device main body 1 and reciprocated on the rails by independent drive devices. An example of this is shown in FIGS. 17 to 19, in which the storage conveyor 8' is separated from the main body 1 and a separate machine frame 65 is provided as shown in the figure.
A mounting bracket 66 is extended to this machine frame, and the conveyor 8' is fixed onto this bracket.

The installation position is the same as in the above embodiment, and is such that when the storage device main body 1 stops at a predetermined position, the conveyor 8' enters directly under the cinch device attached to the device main body. Set to relationship. In this case, as a matter of course, the relay conveyor 17' does not need to be constructed along the rail 16 by the length of the rail, nor is it necessary to provide a driving corner conveyor.
However, FIG. 17 shows an example in which the drive corner conveyor 7' and the relay conveyor 17' are connected in series to the storage conveyor 8'. [Lock Device] The lock device 31 is provided in the upper part of the storage device main body 1.

As shown in FIGS. 2 and 3, frames 19, 19 are attached to the inside of the frames 13, 14 so as to cover the upper side of the storage conveyor 8.

Further, the electric motor 46 is connected to a sprocket 41, a chain 42, a sprocket 43, an electric drive shaft 44, 45, a gear 47, and a wheel 49. The electric motor 46 for driving the hook rotates the wheel 49 to reciprocate the entire hook device on the rail 20. . The knob opening/closing device frames 54 and 55 have guide rollers 61 on the front and rear sides, respectively.
, 55 is suspended by a chain 52 attached to the upper end.

That is, as shown in FIG. 5 and FIG. 9, one of the lock opening/closing device frames 54 does not have a drive source such as a power cylinder, and has a guide rail 62a installed at the lower center of the structural member 21.
It is simply a guided structure. The other lock opening/closing device frames 55, 55 have a power cylinder 56 inside, as shown in FIGS. 5 to 8, and are guided by guide rails 62 vertically provided below both ends of the structural member 21. A pair of fan-shaped racks 59 are pivotally attached to the lower part of the lock opening/closing device frames 54 and 55 with five shafts, maintaining a mutually interlocking relationship.
, 59, and levers 60, 60 which are fixed integrally with the bracket rack are provided with an attachment frame 63 to which a number of attachments 64 are attached. This ume mounting frame 63
is commonly attached near the lower side of each of the lock opening/closing device frames 54, 55, that is, below the horizontal member 21, maintaining the same length as the structural member or a length slightly larger than that. The claw 64 attached to the frame 63 is made, for example, by bending the tip of the plate into an L-shaped cross section, and the bent side is inserted into the handle gap 22 of the side plate of the case 9.

FIG. 5 shows a state in which the attachment frame 63 is lowered, and FIG. 6 shows an enlarged sectional view taken along the line W- in FIG. In this state, the power cylinder 56 is turned off, and the claws 64,
64 is inwardly inclined and closed, and is not engaged with the case 9. When the power cylinder 56 is actuated, the shaft 58
rotates, opens the claws 64, 64 via the racks 59, 59 and levers 57, 57, and presses the tip of the claw against the handle chain 22 of the case 9. Electric motor 3 with the door closed

As described above, when the electric motor 46 for moving the claw is driven while the case is in the raised position or in the lowered position, the entire claw device is reciprocated on the rail 20. Note that the drive source of the above-mentioned lifting drive device and travel drive device is not limited to an electric motor, and may be replaced with either a pneumatic device or a hydraulic device.

The mechanism that holds the case 9 may be a vacuum suction device or an electromagnetic mechanism depending on the shape and material of the case.Also, instead of opening this mechanism from the inside of the case, it is possible to open the case from the outside. It may be changed to hold it down. Furthermore, in the illustrated embodiment, an example is shown in which the locking device is installed inside the storage device main body 1, but the locking device 31 is installed in the storage device main body 1 along with the driving corner conveyor 7 and the storage conveyor 8.
Alternatively, the main body of the storage device alone may be moved back and forth. [Fork] The fork 72 is a device that transfers and holds the case gripped by the pick device 31. When stacking two or more cases on top of the bottom case, the fork 72 transfers and holds the case gripped by the pick device 31. Each time the stacking is completed, the cases are lowered sequentially, and even when descending to the lowest level, there is no interference with the case pedestal 10, and the case can be taken in and out horizontally between the bottom of the case on the case pedestal and the floor surface. It has a structure.

As shown in FIGS. 3 and 12, the fork 72 is attached via a guide 73 that stands on the inside front of the frames 13 and 14 in the device main body 1. Specifically, the fork mounting frame is guided by the guide 73. Many of them are installed horizontally protruding from the bottom of 71. A plurality of guide rollers 86 and 88 are provided on the sides of the fork mounting frame 71 to hold the guide 73 from both sides, and a hanging bolt 75 is provided at the upper end of the mounting frame.

As shown in FIG. 12, the chain 105 is suspended on sprockets 102 to 104 on a daily basis, and its end is connected to a balance weight 107 with rollers 108 guided by the other guide 109 erected inside the frame. . On the other hand, an electric motor 911 for driving the fork up and down is mounted on the side of the beam 15 of the main body of the device, as shown in FIGS. 1 and 10.
are provided, reducer 93 sprocket 94 chain 10
The sprocket 102 is driven through a five-sprocket 96 and a transmission shaft 99.

In this way, the fork 72 can be smoothly moved up and down by the forward or reverse rotation of the electric motor 91. Incidentally, the protruding length of the fork 72 is made to correspond to the width of the cargo (case or cardboard container) 9 to be stored, as shown in FIGS. Set the length so that it does not protrude.

Furthermore, as is clear from the figure, when the fork 72 descends to the lowest position, the cargo placed on the upper part of the fork is transferred to the upper surface of the slatted pedestal 10 laid on the floor of the warehouse. If the fork moves backward, the cargo can be stacked on the cradle 10.
When discharging the baggage on the tray 10, the reverse operation to the above may be performed. In addition, as a safety device when the chain 105 hoisting the fork is broken, the 13th
It is permissible to attach a fall prevention device as shown in Figures 1 and 14.

This device includes a nut 76 for an upper limit stopper provided in the middle of a hanging bolt 75, a stopper 74 provided at the lower end, and a chain 80 fixed to the stopper 74 by a spring 82 attached to the lower end of the chain 80. It is made up of a pair of biased rail holding cams 83 and silk. When the chain 105 is normally tensioned and suspending the fork mounting frame 71 as shown in FIG. A gap is formed and maintained, but if the chain 105 is broken for some reason, the hanging bolt 75 will fall, the chain 80 will become slack, and the force of the spring 82 will rotate the cam and tighten the rail 73. , which acts to prevent the fork from falling. Next, the operation when stacking cases 9 using this device will be explained.

The case 9 sent from the relay conveyor 7 in FIG. 1 is changed direction by the drive corner conveyor 7 and is transferred to the storage conveyor 8 in the main body 1 of the apparatus.

Since the storage container 8 has a stopper 11 at its tip, the transferred cases 9 are stored one after another. When a predetermined number of cases are lined up, the lock opening/closing device frames 54 and 55 located above the storage conveyor 8 are lowered as shown in FIG. By opening the mechanisms 64, 64, the case 9 is grasped from the inside. After that, the lock opening/closing frames 54 and 55 are raised as shown in FIG. Next, the locking device main body 31 is moved on the rail 20 by the operation of the traveling disturbance device 40, and is moved to just above the fork 72, and stopped there. At that position, the locking device frames 54 and 55 are again moved to the case. The case 9 is lowered while being held, and the cases 9 are transferred all at once onto the fork. At this time, the fork 72 is at the uppermost stop position in order to place the first case from the bottom. When the claw opening/closing device frames 54 and 55 located on the fork are lowered to place the case on the fork 72, and then the claw 64 is removed from the case and then raised again, the claw device main body 31 is moved in the opposite direction to the above. Then, the case on the storage conveyor 8 is brought back onto the fork. During this time, the fork carrying the first case has been lowered by the height of one case, and as the lock opening/closing device frames 54 and 55 located on the fork are lowered, they are held by the hook 64. The next group of cases is 1 on the fork.
Stacked on top of tiered cases. Then, the cutter opening/closing device frames 54 and 55 rise again after the clips attached thereto are removed from the case and return to the storage conveyor in the same manner as described above, while the fork further descends by one stage of the case. When the cases are stacked to a predetermined number by repeating this operation, the fork 72 moves to the case holder 1 on the floor.
The stacked cases are lowered from the surface of the case holder 10 without interfering with the case holder 10. ), then storage device main unit 1 is installed in case 1.
Move horizontally by one column (one width). In such a case, the fork will come out of the case placed on the case holder on the floor, so this fork 72 will rise again and move to the top stop position to place the first case from the bottom in the next row. return. In this way, the camera device,
First, a given case can be stored three-dimensionally by the storage device itself repeating a series of organic operations. Next, the case where the stored case is shipped will be explained as follows.

As shown by the iron lines in FIG. 1, the entire apparatus is brought close to the end row of cases 9 that are neatly and three-dimensionally stored on case holders 10 on the floor.

Next, lower the fork 72 from the surface of the case pedestal 10,
Move the storage device main body so that the fork is inserted into the lower surface of the case on the case holder. Next, the lock opening/closing device frames 54 and 55 are positioned on the forks, that is, on the case, and lowered, and when the top case 64 is held, they are raised, and the entire locking device 31 is moved for traveling. By operating the electric motor 46, the device frames 54, 55
After running the case until it moves onto the storage conveyor 8, the gripped case is placed on the storage conveyor 8, and then the handle 64 is removed. Next, the lock opening/closing device frames 54 and 55 are raised and returned to the fork, and the second stage case 9 is held. During this time, the fork 72 rises by one stage of the case and the lock opening/closing devices 64, 55
lowers and puts it in a position where it can hold the second case. When the lowermost case 9 on the fork is held by the lock opening/closing device, the fork descends and is positioned below the case holder 10, and the storage device main body 1 moves horizontally. That is, as the apparatus body 1 moves horizontally, the fork 72 enters the bottom surface of the case in order to place the next row of laminated cases on the case pedestal, and then the fork 72 enters the bottom surface of the case to place the next row of stacked cases to be shipped on the storage conveyor. It will be in a standby state. Incidentally, the cases placed on the storage conveyor 8 are started by releasing the stopper 12, pass through the drive corner conveyor 7, and are sent to the shipping location by the relay conveyor 7. By repeating such a series of operations, the case 9 stored on the pedestal can be quickly shipped. As mentioned above, the cotton invention consists of a storage conveyor, a clipping device, and a fork in the main body of the storage device, and a drainboard-shaped case holder is arranged in the storage space. There is no need to prepare racks or storage frames, and the entire device can be simplified, equipment costs can be significantly reduced, and operation management can be simplified.

In addition, according to the present invention, the area occupied by the mechanical devices for storing or stacking goods is only a small portion of the warehouse floor surface, and it is sufficient to simply lay the rails 16 on the floor surface for these devices to run. Not only can a wide storage space be secured, but also it can be applied arbitrarily and arbitrarily, whether the warehouse floor is wide or narrow, and has a new industrial effect.
