Abstract

PURPOSE:To improve the consistency of level between a support table and a shelf, by constituting an apparatus for storing articles placed on vats such as packed goods or the like such that an elevator is stopped by detecting that the upper face of the support table reaches the same level with the upper face of the shelf. CONSTITUTION:After a carrying-in sensor S1 detects articles carried in, a microcomputer sends an instruction to shift a support table upward or downward with an elevator to the position of a predetermined shelf. The position of the predetermined shelf is detected by counting the number of passing shelves. When the support table reaches the predetermined shelf 4a, the subject shelf 4a is detected by a sensor S2a or sensor S2b depending upon whether the table is lowering or riging: by the sensor S2a when it is lowering and by the sensor S2b when rising. The space between these sensors S2a and S2b is set equal to the thickness of the shelf 4a so that the elevator is stopped upon actuation of the S2a when lowering and of the sensor S2b when rising. With this constitution, the support table can be stopped at the same level with the shelf.

Description

[Detailed description of the invention] The present invention relates to an article storage device.

An article storage device that stores articles, etc., which are loaded with multiple bank products on a vat, into a storage member such as a status card, has a platform on which the articles are placed, and a platform that moves up and down in the main body of the device. an elevator mechanism is provided, storage members having multi-tiered shelves are arranged adjacent to each other on the display stand, the display stand is stopped at a shelf position of a predetermined height, and articles are transferred from the display stand to the shelf. 1) In the article storage device as described above, a reflection type optical sensor is provided on the platform, the shelf position is detected by the sensor, and the elevator mechanism is stopped based on the detection signal. In this case, the following problems may occur.

When the platform moves up, it detects the bottom end of the shelf and stops; when it moves down, it detects the two ends of the shelf and stops.
Even if it is adjusted to either the upward movement or the downward movement of the sleeve, it will deviate by the thickness of the shelf during other movements.

If the loading platform and the shelf are at the same height, the article may collide with the level difference between the loading platform and the shelf when transferring the item from the loading platform to the shelf.
Impact may be applied to the item.

Particularly when the product is one in which a plurality of packaged products are mounted on the bat, there is a risk that the posture of the Bank IiM product will be disturbed or that the flat product will fly out from the top of the bat.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an article storage device in which a loading platform and a shelf are stopped at the same height, thereby smoothly transferring articles.

In the article storage device of the present invention, the article storage device is provided with a sensor for detecting that the top surface of the mounting table and the top surface of the shelf are at the same height, and based on the detection by the sensor. The elevator mechanism is characterized by stopping the elevator mechanism.

An example of the article storage device of the present invention will be explained with reference to the drawings. In the figure, (1) is the main body of the device. ) is installed vertically, and guide rails (LC) are installed on both sides of the front of the frame (1b).

This is the sensor installed in 1).

The sensor (B6) is a sensor for setting the upper limit provided on the top of the device body (1), and the sensor (8,) is the sensor provided on the device body (1).
There is a sensor for setting the lower limit installed at the bottom of the mounting table (3
) reaches any of the sensors (S, ) (S, ), the platform (3) is returned to its initial position and then the elevator mechanism (2) is stopped.

The sensor (B8) is a position detection sensor for detecting whether or not the platform (3) has returned to the initial position for receiving the article, and the sensor (a,) is located at a predetermined position above and below the sensor (B8). (S, , ) are provided respectively.

The sensor (S, XE]
The speed is changed to move the platform (3) at a low speed between , , , ) and at a high speed at positions above the sensor (8,) and below the sensor ("1G)" to improve processing speed. and to prevent sudden stops.

The sensor (S,) detects whether an article is placed on the platform (3), and the sensor (B2) detects whether or not the shelf (4a) is placed on the storage member (4). It is a position detection sensor.

As shown in FIGS. 6 and 7, the sensor (B2) includes a sensor CB2a) for downward movement and a sensor (s, CB2a) for upward movement.
b) The distance between the sensor (S, =) and (s2b) should be approximately equal to the thickness of 11 (4 mm).

For this reason, the sensor (S2a) and (s,
It is preferable to adjust the distance from b).

That is, when moving the platform (3) down, the sensor (S, -
), the shelf (4a) is detected based on the output signal of the sensor (s, b), and when the platform (3) is moved up, the shelf (4a) is detected based on the output signal of the sensor (s, b).
Make sure that the platform (3) and 1111 (4a) are at the same height.

The sensor (81) is a reflective optical sensor that detects whether items are stored in the shelf (4a) and prevents items from being stored in piles. The sensor (8,) is provided on the platform (3) so as to be able to appear and retract from the shelf (4a) of the storage member (4) in conjunction with the driving belt of the pusher (5).
Make it stick out to nearby areas. When the sensor (S3) protrudes near the shelf (4a), the sensor (S,...)
is configured to detect the pusher (5) and stop the protruding movement.

The sensor (S,) detects whether the pusher (5) that has moved forward has retreated and returned to its initial position.When it detects that the pusher (5) has returned to its initial position, the pusher (5) Stop the drive belt.

The sensor (84) detects whether the pusher (5) moves forward and reaches a predetermined position.
) has reached a predetermined position, the drive belt of the pusher (5) is rotated in a y direction, and the drive belt of the pusher (5)

Since the detection signal of the sensor (S4) indicates that the pusher (5) has moved forward and transferred the article, the sensor (S4)
How many shelves (4, ) are detected by counting the number of times they are detected?
It is possible to detect whether the article has been transferred to a).

The embodiment described above is controlled and driven by a control unit equipped with a microprocessor (not shown).

That is, to explain the operation of the article storage device, first, articles are loaded onto the platform (3) manually or by a loading device.

When the sensor (8I) detects the loading and unloading of the article, the microprocessor determines which JIA (4a) from the bottom of the first storage member (4) the article should be stored. This judgment is made based on the microprocessor's memory as to which shelf (4a) from the bottom of the storage member (4) an article is stored.

After determining the position of the shelf (4a), the shelf (4a) is placed on the platform (
3) Determine whether the initial position is above or below. In order to make this judgment, the macro processor must:
The number of shelves of the storage member (4) below the initial position of the platform (3) is memorized. When storing articles 'jk in a new storage member (4) for the first time, either input the number of bundles of the storage member (4) from the operation section (not shown), or move the loading platform (3) to the lower limit sensor (S, ) to count the number of shelves.

When the shelf position for storing articles is above the initial position of the platform (3), the platform (3) is moved upward and the detection signals of the sensors (s, b) are used to detect the shelf position.

Similarly, if the shelf position of the article Q is below the initial position of the loading platform (3), the loading platform (3) is moved down and the detection signal of the sensor (l11.a) is used to detect the shelf position. .

Note that the shelf position where the article J1g is stored is detected by counting the number of passing shelves.

When the sensor (S2) detects that the platform (3) has moved to the predetermined shelf (4a), the belt starts to be driven after stopping the platform (3), and the belt is moved to the shelf (42L).
A sensor (Mo) detects whether an article is already loaded on the container.

When articles are loaded on the shelf (4a), the belt is reversed and the process moves to the next storage order W (4a).

If no articles are loaded on the shelf (4a), drive the belt as is, load the articles Q, and then move to the article loading position (S).
The elevator mechanism (2) is driven to move the platform (3) to a location near 8).

When the storage member (4) is full by repeating the above operation, slide the loading platform (10a) as shown in Fig. 8 and place the empty storage member (4) on the loading platform (3). and replace one full storage member (4) with an empty storage member (4).

When the storage member (4) is full again, open the loading platform (10&)
Slide it in the opposite direction and repeat the above operation.

Next, the second embodiment will be explained with reference to FIGS. 8 to 10.
In this embodiment, the sensor (S2) is composed of only the sensor (S2a).

If the detection voltage generated when receiving the reflected light from the sensor (El, a) is (V), the detection voltage (V ) occurs.

FIG. 9 shows the detected voltage during upward movement, and FIG. 10 shows the detected voltage during downward movement. That is, OFF during upward movement and ON during downward movement are at the same timing, and the elevator mechanism is configured to be stopped at this timing.

This embodiment achieves the same effect as the first embodiment using only one sensor. Further, the other configurations and operations are the same as those of the first embodiment, and their explanations will be omitted.

As described above, the present invention provides a device main body with a platform on which an article is placed and an elevator mechanism that slides the platform up and down, and a storage member having multi-tiered shelves on the platform. In an article storage device in which the writing table is arranged so as to fit together, the writing table is stopped at a sharpening position at a predetermined height, and the article is transferred from the table to the shelf, the writing table is placed on the top surface of the table and the top surface of the shelf. Since the article storage device is configured with a sensor that detects that the heights have become the same, and stops the elevator mechanism based on the detection by the sensor, when the platform is stopped, the top surface of the platform and the shelf are Since the upper surface of the shelf is at the same height as the top surface of the shelf, the transfer of articles from the platform to the shelf becomes extremely smooth.

Thus, the desired goal is achieved.
