Description

[Detailed Description of the Invention] The present invention relates to equipment for storing heavy objects such as jigs and molds.

Generally, when loading or unloading cargo into or out of a rack, the cargo placed on a pallet is moved in and out using a forklift, but in this case a dedicated passage for the forklift is required, and the rack installation space is limited. Floor space is not used effectively. For this reason, slide the drawer in the depth direction and use the overhead traveling crane with the drawer pulled out from the rack.
There is a method of loading and unloading cargo on a drawer using a hoist, etc., but if the cargo is light, the worker can pull out the drawer directly, but it is difficult to place and store heavy objects such as jigs and molds. If the drawer weighs 2 to 3 tons, it is impossible and dangerous for the worker to pull it out directly.

The present invention does not cause the above-mentioned problems, and allows an operator to safely and easily pull out a drawer containing stored items weighing 2 to 3 tons by hand, and
To provide a heavy object storage facility which can completely prevent accidents such as sudden protrusion of a drawer due to the inclination of a floor surface, etc., and accidental withdrawal or falling of the drawer in the protruded state.

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, the rack 1 is a column 2a,
2b and 3a, the cross beams 4, 4 and the pillar 2a between 3b,
A frame is constituted by the cross beams 5, 5 between 3a and 2b, 3b, and brackets 6, 6 are attached to the supports 2a, 3 at each stage of the rack, that is, at the front opening of each article storage compartment.
bearings 7, 7 of the brackets 6, 6.
A connecting shaft 8 is inserted between them, and drawer mounting rollers 9, 9 are fixed to both ends of the shaft 8, and as the shaft 8 rotates, the left and right rollers 9, 9 rotate simultaneously.

In addition, the front and rear supports 2a, 2b and 3 of the rack
A guide rail 10 shown in FIG. 3 is fixed to each article storage compartment (each stage) between a and 3b, and a roller 13 pivotally supported 12 at the rear end of the drawer 11 rolls along the guide rail 10. The drawer 11 may be constructed by passing and fixing a cross beam 15 between the U-shaped steels 14, 14 on both sides as shown in the first diagram, or by fixing the crossbeam 15 between the U-shaped steels 14, 14 on both sides.
A type with a flat plate fixed in between is used. Reference numeral 16 in the third diagram indicates a reinforcing beam for the drawer.

Further, as shown in FIG. 3, cam-shaped stoppers 17 and 18 are fixed to the front end and intermediate portion of the drawer 11. As shown in FIG. The stopper 17 is used to prevent the drawer from accidentally advancing forward when it is stored; that is, the front surface 17a engages with the stop pin 19, and the upper surface 17
b is an inclined surface that becomes lower toward the rear. On the other hand, a stopper 18 in the middle of the drawer prevents the drawer from returning when it is pulled out, and its rear surface 18a engages with a stop pin 19, and its upper surface 18b has an inclined surface that becomes lower toward the front.

The stop pin 19 that engages the stoppers 17 and 18 is connected to a shaft 2 fixed to the support column 2a as shown in the fourth figure.
The lever 21 is fixed to the tip of a hook lever 21 which is rotatably supported on the shaft, and a rod 22 for operation by an operator is fixed to the opposite side of the lever 21 from the pin 19. Normally, the tip of the lever 21 is in contact with the upper surface of the drawer 11, and the stopper 17 or 18 passes through the stop pin 19 when the operator temporarily lifts it up when pulling out or storing the drawer.

Furthermore, as shown in FIGS. 3 and 5, the drawer 11
A stop plate 23 is fixed to the rear end, and is engaged with a stopper 24 fixed to the rack-side guide rail 10, thereby regulating the most advanced position of the drawer. In other words,
Breaking out is prevented. The fixing position of the stopper 24 is set within a safe range to prevent the rack from falling or damage to the drawer due to deflection when the drawer on which a heavy object is placed is pulled out.

At the end of the connecting shaft 8 of the roller 9, which is pivotally supported in the front opening of the rack, there are formed engagement teeth 26 having a spline, a square cross section, a hexagonal shape, etc. that can be engaged with the ratchet handle 25. (Fig. 4), if a known ratchet handle that can rotate in one direction or in both forward and reverse directions, such as the ratchet handle for socket trenches according to JIS standard B4641, is engaged with the 8 ends of the connecting shaft and rotated, a pair of left and right The rollers 9 rotate at the same time, and the drawer 11 on the rollers 9 can be smoothly pulled out forward or retracted backward without rattling.

When the front drawer is drawn out, the stopper 17 and the stop pin 19 and the stop plate 23 and the stopper 24
As mentioned above, these are locked to prevent unexpected forward protrusion or slippage.

Next, the operation of pulling out and storing the drawer on which a heavy object is placed will be explained.

When pulling out the drawer 11 on which a heavy object W is placed as shown in FIG. 2 from the rack 1, insert the ratchet handle 25 shown in FIG. Axis 20 to position
The handle 25 is rotated intermittently under this condition to simultaneously rotate the left and right rollers 9, 9, and the drawer 11 is moved forward. In other words, drawer 1
1, the lower surface of the drawer rolls into contact with the left and right rollers 9 as shown in the third figure, and the roller 13 pivotally supported on the drawer itself moves forward in the direction of arrow X while rolling on a guide rail 10 fixed to a support.

Once the front end stopper 17 fixed on the drawer passes below the stop pin 19, the operator can place the lever 21 in its original position, that is, on the upper surface of the drawer.

Furthermore, by intermittently turning the handle 25, the drawer 11 moves forward, and when it reaches the vicinity of the most advanced position, the stop pin 19 engages with the inclined surface 18b of the stopper 18 in the middle of the drawer shown in the third figure, causing the drawer to move further. The stop pin 19 then relatively climbs over the stopper 18 and comes into contact with the upper surface of the drawer on the engaging surface 18a side. Further, the drawing of the drawer is completed at the position where the stop plate 23 at the rear end of the drawer engages with the stopper 24 fixed on the rail 10. Of course, movement forward from the locking position is prevented, and slipping out is completely prevented.

Therefore, the drawer 11 pulled out as shown in the sixth figure
The operator M can safely remove the heavy object W from the drawer by operating the hoist 27 or the like.

An empty drawer can be easily stored into the rack by the rollers 9 and 13 by the operator temporarily lifting the lever 21 and pushing the drawer in without using the ratchet handle. Of course, if you want to pull out an empty drawer and store a drawer with a heavy object placed on it, use the ratchet handle 25 to rotate the shaft 8 of the roller 9 in the opposite direction, such as by operating the pawl switching lever on the ratchet handle.
By rotating intermittently, the rack can be stored in the rack while performing a reverse movement to the above-mentioned pull-out operation.

As described above, in the rack according to the present invention, even if the drawer is loaded with a large amount of stored items, the ratchet handle can be attached to the end of the connecting shaft 8 as appropriate, and the rack can be turned easily by hand. The stoppers 23 and 24 completely prevent the drawer from falling out, which can easily occur due to the fact that the drawer can be pulled out and stored, and the drawer can be easily pulled out. 2
1 prevents the drawer from unexpectedly protruding and retracting in the protruded state, ensuring complete safety.

In addition, the pair of rollers on the front side that support the drawer rotate at the same time to move the drawer, so even if the stored items are extremely heavy (2 to 3 tons), the drawer can be moved extremely smoothly without wobbling or getting caught. Can be stored in a drawer.

Furthermore, when the ratchet handle is not attached, the end of the connecting shaft 8 is just a shaft that slightly protrudes from the roller 9, so it may become a hindrance when taking out and taking out stored items, or it may get caught on the worker's clothes, causing an unexpected accident. There is no risk of it happening.
