Then, the stopper device 29 is actuated to engage a stopper member 29a with the pallet 14''. Subsequently, the elevating device 16 is lowered by a predetermined stroke to define an access space S between the pallets 14', 14'' to permit access to the articles in the pallet 14'.

Description

[Detailed Description of the Invention] <Background of the Invention> Technical Field The present invention relates to a method for storing and taking out films, paper-1, and various other articles from a pallet at a desired stage by raising and lowering the pallet to a certain height. The present invention relates to a multi-stage pallet device.

Prior Art For example, a fully automatic plate-making film making device is available for making plate-making film for PS plates, but this device requires a multi-stage pallet device to store and take out the film. It is.

In other words, the fully automatic plate making film creation device is comprised of a printer, a multi-stage pallet device, and a transport means.

The transfer means is preferably an industrial Kawaguchi bot, which has a film gripper having a suction band for adsorbing the film at the tip of a robot arm as a hand, and is housed in a multi-stage valent device. The mask plate, embedding plate, character plate, folding plate, and raw film are transferred to the printer, and after exposure is completed, they are transferred again to the valent device.

Figure 1 shows a multi-stage pallet! ＜This shows the multi-tiered pallet B placed on the platform A.

In the elevator A, a cart 2 and a lifting plate 3 are connected by a cross-shaped link mechanism l that moves in parallel, and the lifting plate 3 is guided by a guide post 4 that stands up from the cart 2, so that the lifting plate 3 is in a horizontal state. It is possible to move vertically while maintaining the
The wave pressure cylinder device 5 provided from the truck 2 raises the link mechanism 1, so that the elevating plate 3 is raised.

The multi-stage pallet B has the balents 6 divided into at least three stages, seven stages in the figure, and is suspended horizontally by connecting members 7 at intervals of a predetermined pitch.

C is a film gripping tool for storing and taking out the film F from the pallet 6, and has a suction band 8 for suctioning the film F, and when it is located between the balents, the suction pad 8 Film F on pallet
The size is slightly lowered by the motor 9 so that the electrodeposition is made. Further, D is the hard part of the industrial robot, which is controlled by, for example, an 8-pin microcomputer and is movable in a horizontal plane.

Initially, the mask plate, inset plate, character plate, wrap plate, and raw film F are artificially separated and stored on pallets 6''-, and the necessary types of film F are placed in predetermined stages. To take out the pallet 6, use the AV4 machine A to lower the balent y1 so that the film gripping tool C enters the desired stage of the balent 6'', and then move the hunt part of the industrial Ropon. The film gripping tool C is inserted onto the pallet 6 of the desired stage, and is lowered by the required distance by the motor 9. After the film F on the balent is sucked by the suction pad 8, the film gripping tool C is raised and further removed from between the pallets. This will force you to leave.

However, since this pallet device has gaps between the pallets to allow the film gripping tool C to go in and out, it is not possible to increase the number of stages of pallets 6, and if the number of stages of pallets 6 is increased, As the height increases, the lifting stroke becomes larger, which results in a larger elevator and a disadvantage that the installation becomes larger.

<Object of the Invention> The present invention has been made in view of the above-mentioned problems, and the space between the pallets can be significantly narrowed compared to the conventional one, thereby minimizing R-drop and A-rolling of the valentine. It is possible to increase the number of stages, is compact, and has a small footprint, and moreover, the pallet of the desired stage for taking out films, etc. can have sufficient clearance with the pallet of the other stage, and furthermore, the pallet of the desired stage for taking out films etc. To provide a multi-stage valent device that requires a short period of time to reach a state where it is possible to take out a film or the like from a pallet, and whose operating circuit can be configured for mass production.

Furthermore, the present invention provides a multi-tiered pallet that can be used not only as a multi-tiered pallet device required for a fully automatic plate-making film production device, but also as a stock shelf for storing a wide variety of items in warehouse systems and distribution systems. It provides equipment.

<A configuration of the invention> The multi-stage balent device of the present invention engages a lifting kite extending in the vertical direction, at least three or more stages of balents guided by this row of descending kites, and a lowermost pallet). and a stopper device δ that engages and stops a pallet on any stage that comes to that position at a required height.1. Then, in the stopper state, stop the pallet one level higher than the desired level pallet from which you want to store or take out items, and use the R unloading device to lower the pallet in the desired level to meet the pallet one level higher. The four temple signs are that they are spaced apart.

Therefore, when the pallet one step below the desired pallet from which to store or take out articles comes to the position where it is stopped by the switch/flange device, the stopper device becomes the stopper state, and then Since the balent of the desired stage is lowered by a predetermined stroke to open a space between it and the balent of the desired stage, articles can be taken out or placed on the pallet of the desired stage.

In addition, in order to change the stage and take out the article from the barrento or put it away, it is necessary to wait until the barrento of the desired stage is east of the barrento which is currently stopped by the stopper device.
If the lowering device is used to release the stomper, the barrent that has been stopped until now will not fall to the desired stage, and after that, it will be one step higher than the barents in the other stages. It is sufficient if the lifting device is driven so that the balent is at the position where it is stopped by the stopper device.

The Y1 Ryu kite can be, for example, one or more tie rods that integrally connect a floor plate and a ceiling plate,
Alternatively, when the apparatus ξ of the present invention is installed as a warehouse system, the upper end and the lower end can be provided so as to be supported by the wall defining the shaft space of the building.

The balent is provided in multiple stages of at least three or more stages, and has an engaging part that is guided to the y1 descending kite. A pole neck is provided that extends parallel to the pole neck, and the bottom row of the pole neck is combined with a hole neck provided from the lower part.The pole neck is rotated by a motor. The highest tier valent through Natsuto! It is possible to have a configuration in which the height is increased by one.

On the other side, the y1 lowering device can also be configured such that one point of the end chain is connected to the lowest pallet, and the endless chain is stroke-driven by a motor or cylinder device to lower the lowest balent. .

That's fine.

The pallets other than the lowest stage are only engaged and guided by the If lowering guide using the above-mentioned engaging portions, so that they can be lowered R-5 by the lowermost balent.

For example, a magnetic device is used to drive a magnetor j.
The Ll damper body can be configured to rotate or protrude and retire to engage with a desired part of the pellet and stop. Further, the stopper device is installed at a height that ensures a dimension corresponding to the gain height, y, of all valents on one side and below, respectively.

For each balent other than the bottom row, leave a gap between the pallets,
The upper pallet may be supported by a stopper body of a stopper device that moves in and out of this gap.

Moreover, each pallet other than the bottom layer can be stacked without ensuring a gap between the pallets. However, in this case, a notch is provided in the pallet, and the stopper body that goes in and out of this notch supports the heel 1/soi on the - side. Alternatively, a hook part that fits into the wooden body may be attached.

<Embodiment> FIGS. 2 and 3 show a preferred embodiment of the multi-stage pallet apparatus of the present invention.

This device is installed so as to connect the lifting kite 1O110 or the floorboard 11 and the ceiling board 12, and the floorboard 1
A large number of valents 14.14 between 1 and the ceiling plate 12
, .

Each pallet 14 has a boss 15.15 that slides onto the two R landing kites IO and is supported horizontally by this boss.

The lifting device 16 for raising and lowering the pallet 7+-14 uses a motor 17 as a driving source, and the rotation of the motor 17 is transferred to the sprocket 21 via the bell I/wheel 18, the heald j9, and the belt east 20. Transmit rotation and furthermore chain〉'22
The upper, end, and lower ends of the Nupro Ken I.
24 to transmit rotation.

A pole screw 25 is screwed to this pole screw 23, and this NAND 25 is connected to the two-piece lifting kite 10, IO.
The connecting plate 26 is engaged with the connecting plate 26, and furthermore, the connecting plate 6 is connected to the balent 14 of the Saito role. It is said that he is riding on the highest tier of valentines. Also, this pole screw 2
3 is a two-piece lifting kite 10.10 between the two.
2. Each pallet 14 is provided with a hole 27 through which the hole 23 passes.

When the motor 17 rotates the pole screw 23 once, the pole screw nut 25 is raised or lowered, and the pallet 14 is accordingly raised or lowered.

A stopper device 29 is provided in the middle of the frame 28 extending between the ceiling board 12 and the floor board 11, and this stopper device 28
When 1 is energized, the magnet is excited and strikes.
The stopper body 29a enters the notch 30 of the pallet 14 and supports the pallet 14 on the second side thereof, and then the ballet below the stopper body 29a is lowered by a slight stroke S. For example, at a predetermined height, a large gap can be created between a pallet in a desired stage and a pallet in the next stage above it.

The elevating guide 1O11O and the pole screw 23 are hidden by a rear cover panel 31, and drive parts such as the motor 17 are hidden by a drive part cover panel 32. The distance from the ceiling panel 12 to the drive unit cupboard 32 is determined by the ζ method plus twice the overlapping height H of all balents, and the balent spacing S required for storing and taking out films, etc. is ensured. The stopper device 16 is installed above and below at a height that ensures a dimension corresponding to the overlapping height H of all the pallets.

To explain the operation of the multi-stage pallet device of the present invention, first, when a number corresponding to a desired stage pallet from which a film or the like is to be taken out or stored is pressed on the control section (not shown), the lifting device 16 is operated at the desired stage. The pallet 14 of the tier is driven until it reaches the required height where it is stopped by the lift device 29 at the balent level one step higher than the pallet 1 river 4, and the pallet 14 on the lowest tier is connected to the lifting device 16. In addition, the balent 14 other than the bottom row has a lifting force of
is guided by the lifting kite and lifted or lowered.

Then, when the pallet one level higher than the desired level reaches the height where it is stopped by the stomper device 29,
The lifting device 16 is moved out of operation, so that all valents cease to rise or fall.

Then, the stopper device 28 is activated and the stopper body 29a is activated.
This results in stopping the pa- t which is higher than the desired level of pallet.

Subsequently, the lifting device 1G lowers the lowermost balent 14 by a predetermined stroke, so that the pallets from the bottom 2nd tier 1'' to the desired tier pallet are lowered together with the lowermost balent 1. .

Therefore, the pallet of the desired stage where you want to take out or store films etc. is always located at a predetermined height.
Therefore, a sufficient gap is ensured between the balent at the desired stage and the balent one stage above it, so that films and the like can be stored in and taken out from the pallet at the desired stage.

Next, if you want to store or take out films, etc. from the pallet in another stage, press the number corresponding to that stage on the control unit, and the y1 unloading device 29 will then move the balent 14 on the bottom stage to the second stage. Only for the downward stroke of the desired step.
The second stage is raised to close the gap between the pallet of the desired stage and the pallet of the first stage stopped by the stopper device.

Then, the stopper body 29a of the stomper device is retracted and disengaged from the pallet. Therefore, the pallet that has been stopped by the stopper device will not fall onto the pallet of the desired stage due to disengagement.

From this point forward, in the same way as described above, the y-lowering device will be driven until the balent above the level on that side reaches the required height at which it is stopped by the stopper device, and all pallets are It will be upper J7 or lowered.

<Effects of the Invention> As explained above, the multi-stage pallet device of the present invention has three or more stones in the pallet I, which are guided in the lower cutting direction by the falling guide. The Y1 unloading device engages the lowest pallet to lower it A, and the I/sumper device engages and stops any pallet at the desired height. The pallet at the level below the desired level from which you want to store or take out is stopped by the spa device, and then the pallet at the desired level is lowered by the lifting device and moved to the pallet one level above. The structure is such that there is a gap between the two.

Therefore, the multi-stage pallet device of the present invention does not require gaps between the pallets, and the lowering device does not have a rising link mechanism unlike the conventional structure, and the lifting stroke is large. Since the structure has no effect on the overall length or floor area, the lifting stroke of the pallet can be minimized, and the number of balent stages can be increased to an incomparable extent compared to conventional equipment. It is smaller and requires less installation space.

At the same time, the pallet in the desired stage for taking out films, etc. can have sufficient clearance with the pallet one step above it, and furthermore, the pallet in the desired stage for taking out or storing films, etc. can be taken from the lower stage to the upper stage. Even when changing the stage, the required time is short because the lifting stroke is small.

Furthermore, it is enough to stop the pallet one level higher than the pallet in the desired level using the stopper device, and then lower the pallet in the desired level using the lifting device to open up a gap between the pallet and the pallet in the other level. When you want to store or take out a film, etc. from a barrento, the stopper device closes the gap between the pallet in the desired stage and the stopped pallets in the first and second stages, and then the stopper device The operation circuit can also be easily constructed because all that is required is to release the connection and, after a certain amount of time, cause the lifting device to stop the pallet one level higher than the pallet on the relevant side by the stopper device.
