Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a storage device that continuously stores and holds an object by utilizing its own weight and inertia, and can easily take out the object that has been stored and held. .

(Prior art) Conventionally, when storing an object at a high position in a storage device at a low position, if the object is heavy enough to be transported by human power, it is necessary to rely on human power or to store a soft object at a low position. Generally, this was done by laying out cushioning material and dropping it on top of it, or by using a suitable conveyor as an emergency measure.

Furthermore, it has generally been the case that objects to be transported are manually arranged and stored in storage devices.

(Problems to be solved by the invention) As mentioned above, when storing objects at a high position in a storage device at a low position, relying only on human power is not efficient, and There is a high risk that the product may fall due to carelessness, damaging the transported object or causing personal injury.

In addition, even if items are dropped on top of cushioning material, the dropped items must be sorted and stored, and there must be sufficient communication between those who organize and store items on the lower side and those who drop them on the upper side. Otherwise, not only will the risk of personal injury below still be eliminated, but
Damage to the transported object cannot be avoided.

Further, when a conveyor is used, it is only an emergency situation and is not generally used, and even in this case, manual labor must be relied upon before and after the conveyor.

It is an object of the present invention to solve the above-mentioned problems and provide a storage device that can store heavy items safely and quickly while reducing the need for manual labor as much as possible.

(Means for solving the problem) In order to achieve the above-mentioned purpose, a plurality of cylindrical storage tubes 6 are provided on the circumference, and the mount 2

The buffer means 10 is equipped with a buffer spring 8 and a receiving plate 9.

(Function) The conveyed object 25 that has been conveyed by the chute from a high position slides into the storage cylinder 6 in the storage position, is decelerated and stopped by the buffer means 10, and at the same time is automatically stopped by the holding means 26. It is held securely and will not slip out until it is released.

(Example) FIG. 1 is a front view (partially in section) of the main parts of the storage device of the present invention, and FIG. 2 is a side view as seen from the entrance side of objects 25 to be transported. 1 is the main body of the storage machine, and a shaft 5 is held by bearings 3 and 4 provided on both sides of the pedestal 2.
It is held rotatably. This storage machine body 1
Cylindrical storage tubes 6 are arranged at regular intervals on the outer circumference of the shaft 5.
Multiple pieces are provided in parallel to each other. Further, the storage machine main body 1 is linked to a drive device 7 provided at one end of the shaft 5.

At the upper part of the bearing 3 side of the gantry 2 (the side opposite to the side where the transported object 25 slides in, the left side in FIG. 1), at a position opposite to the rear end surface 6-1 of the storage cylinder 6 in the storage position. Buffer means 10 consisting of a buffer spring 8 and a receiving plate 9
A chute 11 is provided at the upper part of the bearing 4 side (the side into which the transported object 25 slides in, the right side in FIG. 1), at a position facing the inlet end surface 6-4 of the storage cylinder 6 in the storage position. A pedestal 12 for holding the is provided.

As shown in the plan view of FIG. 5 and the side (cross-sectional) view of FIG. The restriction fitting 13 and the ratchet 14 are inserted into the pins 15 and 16.
and is pivotally supported by brackets 17 and 18 to constitute a holding means 26. Back end surface 6 of storage tube 6
Spring mounting hole 19-1 of boss 19 provided in -1
and a spring mounting hole 13-1 provided in the restriction fitting 13.
A tension spring 20 is provided between them. In addition, a compression spring 2 is placed inside the spring tube 6-3 provided in the storage tube 6.
1 and a push rod 22, the tip of the push rod 22 is in contact with the ratchet 14.

The pawl 14-1 of the ratchet 14 and the pawl 13-2 of the limit fitting 13 are brought into contact with each other by the spring force of the stopper 23 and the compression spring 21.

The limit switch 24 is provided on the pedestal 2 so as to come into contact with the outer periphery of the spring cylinder 6-3 of the storage cylinder 6, as shown in the third figure.

Next, the operation of the storage device described above will be explained.
The transported object 25 used in this storage device includes a cylindrical body part 25-2 and a flange 25-2 provided at one end of the body part 25-2.
It consists of 1. Mating surface 1 of chute 11
The storage machine main body 1 is rotated by the drive device 7 to a position where the entrance end face 6-4 of the storage tube 6 and the storage cylinder 6 are aligned, that is, to the storage position, and the limit switch 24 is used to accurately align the storage machine body 1. The conveyed object 25 slides down from a high position inside the chute 11 with the collar 25-1 at the top due to its own weight and inertia, and slides down the mating surface 11-1 of the chute 11 and the inlet end surface 6-4 of the storage cylinder 6. It passes through and reaches the inner end surface 6-1 inside the storage cylinder 6. Immediately before reaching the rear end surface 6-1, the collar 25-1 of the conveyed object 25 comes into contact with the lever 14-2 of the ratchet 14 as shown in the fourth figure, and then the ratchet 14 is moved by the compression spring 21 as shown in the sixth figure. It springs up against the force around the pin 16, then hits the lever 13-3 of the limit fitting 13, flips the limit fitting 13 up against the force of the tension spring 20, and finally moves forward. As shown in the figure, it advances through the receiving plate 9 until the buffer spring 8 is compressed. At this time, the buffer spring 8 is biased, so that the object 25 to be transported is pushed back in the opposite direction after the movement of the object 25 is stopped. When the transported object 25 compresses the buffer spring 8, the limit fitting 13 is moved by the lever 13 due to the spring restoring force of the tension spring 20.
Since the lever 13-3 is in contact with the body portion 25-2 of the transported object 25, even if the transported object 25 is pushed back in the opposite direction, the lever 13-3 is moved to the flange 25-1 as shown in the eighth figure. The conveyed object 25 is caught in the storage cylinder 6.
securely held within.

Next, the relationship between the limiting fitting 13 and the ratchet 14 will be explained. The ratchet 14 acts as a stopper for the limiting fitting 13, and is provided in a relative position as shown in FIG. That is, the distance A between the end of the lever 14-2 of the ratchet 14 and the end 13-4 on the ratchet 14 side of the contact surface between the lever 13-3 of the limiting fitting 13 and the collar 25-1 is equal to the thickness of the collar 25-1. It is smaller than B. As a result, as shown in FIG. 6, the collar 25-1 of the transported object 25
When the lever 14-2 is pushed up, the ratchet 1
4 is sprung up, and at the same time, the engagement between the claw 14-1 and the claw 13-2 of the restriction metal fitting 13 is released, so the restriction metal fitting 13 is released from its restraint, and the conveyed object 25 moves forward until it reaches the collar 25-1. is the ratchet 14 of the lever 13-3.
When the lever 13-3 is pushed up by contacting the side end 13-4, the tip of the lever 14-2 is still attached to the tsuba 2.
5-1, the restricting metal fitting 13 remains in the unrestricted state. Therefore, in this state, the conveyed object 25 can move forward until it comes into contact with the receiving plate 9, and can move forward until it presses this and compresses the buffer spring 8. At this time, the tsuba 25-1 is attached to the lever 13.
-3, the limit fitting 13 is rotated by the restoring force of the tension spring 20, and the tip of the lever 13-3 is inserted into the body part 25-2 of the object 25.
comes into contact with.

When this state is reached, the lever 14-2 of the ratchet 14 has also come off the collar 25-1, so the restoring force of the spring 21 is applied to the body part of the object 25.
5-2, the claw 13-2 and the claw 14-1 engage with each other, and the restriction fitting 13 becomes in a restrained state again.

Further, after storing the transported object 25 in the storage cylinder 6, when the storage machine main body 1 is rotated so that the transported object 25 is in the position directly below as shown in Figure 10, the transported object 25 and the restriction fitting 13 are The relationship is that lever 13-3 is tsuba 25
At this time, the weight of the transported object 25 is applied to the lever 13-3 and attempts to rotate the restriction fitting 13 against the tension spring 20. , claw 14-1 of ratchet 14
Since the limit fitting 13 is engaged with the claw 13-2 of the restriction fitting 13, the restriction fitting 13 cannot be rotated, and the restraint of the conveyed object 25 is not released. That is, the transported object 2
Once 5 is restrained, unless the engagement between the ratchet 14 and the restriction fitting 13 is manually released, the storage machine main body 1 will rotate and the transported object 25 stored in the storage tube 6 will be on the lower side. However, the object 25 to be transported inside the storage tube 6 is reliably accommodated by the restriction fitting 13.

Next, the transported object 2 stored in the storage cylinder 6 is
5, as shown in Figure 9, the ratchet 14 is rotated and held in the release direction (in the direction of the arrow in the figure) by human power or the like against the compression spring 21.
and the restriction fitting 13, and then the restriction fitting 1
3 is rotated in the direction of the arrow in the same direction against the tension spring 20, the engagement between the lever 13-3 and the collar 25-1 is released. It can be easily taken out from the storage tube 6 by pushing it out from the end surface 6-1 (or by pulling it out from the entrance end surface 6-4 of the storage tube 6).

(Effects of the Invention) As described above, according to the storage device of the present invention, the transported objects 25 can be stored efficiently, reliably and safely without being damaged.
