Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of an apparatus for transporting shaped articles and loading and unloading them into and out of shelves and other insertion slots.

The operation of loading and unloading articles from ordinary shelves can be automated by providing a suitable article clamping device on a movable carriage along the front of the shelf, movable towards or away from the shelf. be.
However, for example, video cassette tapes (hereinafter referred to as "tapes") are stored on many shelves.
It is generally not possible to automate the task of taking out any one piece of video tape and setting it in a video tape recorder (hereinafter referred to as ``video''), even if the video tape is of the type that accepts tapes in the front tape slot. It's difficult. This is because in this type of video recorder, the tape cannot be set unless the tape is inserted deep into the tape insertion slot; however, if the tape is still being held, the tip of the holding device may collide with the front of the video. This is due to the fact that the tape cannot be inserted sufficiently.

Therefore, it is an object of the present invention to provide a conveyor table with a holding device for holding and pulling in articles, and an extrusion device for pushing out articles without having to worry about the position of the tip of the holding device. The goal is to provide transportation equipment.

A further object of the present invention is to provide a fixed-sized article loading/unloading/transporting device that makes it possible to automate the task of taking out any one of the tapes stored on a large number of shelves and setting it on a video tape.

According to the present invention, there is provided a conveyance platform movable along the front surface of a shelf for storing fixed-sized articles, a frame movably provided on the conveyance platform in a direction toward or away from the shelf, and a frame movable along the front surface of a shelf for storing regular articles; a drive mechanism that moves the shelf toward or away from the shelf;
a chucking device that is movably mounted on the frame in the direction of moving toward or away from the shelf, and is configured to be able to clamp regular shaped articles on the shelf and pull them onto the conveyance table; A return spring biased toward the shelf, and a return spring provided in the frame so as to be movable in the direction toward or away from the shelf, the tip of which faces the front surface of the shaped article on the conveyance table. a push shaft, a push spring that biases the push shaft in a direction toward the shelf relative to the frame, and a lock that stops only the movement of the chucking device in the direction toward the shelf with respect to the conveyance table midway. A shaped article loading/unloading/transporting device is obtained.

According to the shaped article loading and unloading device of the present invention, when the frame is brought close to the shelf by the drive mechanism, both the chucking device and the push shaft are initially carried by the frame, but only the chucking device is stopped midway. The push shaft alone is then carried by the frame towards the shelf to push the shaped articles. At this time, if the movement of the shaped article is prevented by some kind of obstacle, even if the push shaft moves with further biasing of the push spring,
It is safe because it detects any abnormality in the motor and stops it. Therefore, it is possible to automate the task of reliably inserting the tape deep into a small tape insertion slot such as the one for the video tape described above. Note that when the frame is moved away from the shelf, the chucking device is returned to its original position relative to the frame by the return spring.

Examples will be described below with reference to the drawings.

FIG. 1 shows an article storage apparatus suitable for use with the apparatus for carrying in and out of regular articles according to the present invention.
In FIG. 1, a column 4 movable in the left and right direction is placed opposite to the front surface of a shelving device 3 which is formed by providing a plurality of shelves 2 between a plurality of shelf pillars 1.
A fixed-shaped article loading/unloading/transporting device 5 is provided on this column 4 so as to be movable up and down. In this way, the fixed-sized article loading/unloading/transporting device 5 is moved vertically and horizontally along the front surface of the shelf device 3, and operations such as taking out a fixed-sized article such as a tape from a desired shelf 2 and storing the tape on a predetermined shelf 2 are automatically carried out. I try to do it. A video 6 is also built into this shelf device 3, so that tapes can be automatically taken in and out of this video 6 as well. It is assumed that the video 6 has a tape insertion slot 6a on the front side.

In the fixed-shaped article loading and unloading conveying device 5, referring also to FIGS. 2 and 3, the conveyor table 7 is
A pair of long guide shafts 9 are provided, and a frame 11 made of blocks or the like is slidably assembled to these guide shafts 9. The frame 11 is connected to a chain 14 that extends between the front and rear sprockets 12 and 13, and can be transported in the front-rear direction 8 by a motor 15 that rotationally drives the rear sprocket 13.

The frame 11 is provided with a pair of push shafts 16 that are long in the front-rear direction 8 and are slidable in the axial direction. The push shafts 16 are each urged forward, that is, toward the shelf device 3, by a push spring 17. Note that the push shaft 16 is prevented from coming off forward by, for example, providing an E-ring or the like at the rear end and locking it to the frame 11.

A sliding block 18 is supported by the pair of push shafts 16 so as to be slidable in the front-rear direction 8, and is urged forward by a return spring 19. Note that the sliding range of the sliding block 18 is limited by the frame 11.

A chucking device 21 is assembled between the two sliding blocks 18. Therefore, the chucking device 21 is also movable in the front-rear direction 8. The chucking device 21 is configured to open and close the front ends of a pair of finger members 23 at the front depending on whether or not a solenoid 22 at the rear is energized, thereby gripping or releasing the tape. It is something. The solenoid 22 is fixedly held by a plate 24 fixed to the sliding block 18, and the rear end of the finger member 23 is rotatably supported by the sliding block 18 by a pin 25. A solenoid shaft 26, which is moved back and forth by a solenoid 22, is connected to the finger member 23 via a link mechanism 27. Thus, by controlling the energization of the solenoid 22, the finger member 2
3 drives are possible.

Furthermore, a stopper 28 is fixed to the upper surface of the plate 24, and on the other hand, a stopper 28 is also provided on the conveyor table 7 to prevent the stopper 28 from moving forward at a certain position.
9 is fixed. The position where the stoppers 28 and 29 engage with each other is preferably a position where the tip of the finger member 23 reaches just before the front surface of the shelf device 3.

Further, at a relatively front portion of the conveyance table 7, there is an article guide 31 for guiding the tape in and out of the conveyance table 7.
is provided.

FIG. 4 shows an example of the operation of inserting a tape into the tape insertion slot 6a of the video 6 using such a fixed-shaped article loading/unloading/transporting device 5. Referring to Figure 4,
With the tape 32 held between the pair of finger members 23, first move the frame 11 in a direction approaching the video 6, and insert most of the tape 32 into the tape insertion slot of the video 6, as shown in FIG. 4a. insert. Just before the tip of the finger member 23 collides with the video 6, the solenoid 22 releases the tape 32 from being held by the finger member 23. Next, frame 11 is moved further toward video 6. At this time, the stopper 28,2
9 prevents the finger member 23 from advancing. Thereafter, therefore, the tape 32 is pushed deep into the tape insertion slot of the video 6 by the push shaft 16. In this way, the tape can be set reliably.

When the frame 11 is moved away from the video 6 after the tape 32 has been set, the finger member 23 is returned to its original position by the return spring 19.

In the above description, the tape 32 is held between the pair of finger members 23 until the middle of the tape insertion work, but the tape 32 is released from the grip from the beginning of the tape insertion work, The tape can be reliably set on the video tape 6 by pushing it only by the push shaft 16 while being guided by the article guide 31.

In addition, the work of drawing the tape 32 into the conveyor table 7 is as follows.
As shown in FIG. 4a, the tape 32 may be held between the finger members 23 and the frame 11 may be moved away from the video 6 in this state.

By the way, it is preferable that switches for detecting the position of the frame 11 be provided and the opening/closing of the finger member 23, the movement/stopping of the frame 11, etc. be performed based on the operation of these switches.

Although the special case of setting the tape 32 on the video 6 has been described, it goes without saying that the present invention can be implemented in the same way when dealing with other shaped articles.
