The structure is such that after the front parts box placed on the auxiliary member is removed, the subsequent parts box is sent out.

Therefore, a function that reliably guarantees that parts are not taken out incorrectly has not been provided.

The purpose of this invention is to solve the technical problem of the integrated component shelf based on the above-mentioned conventional technology, and to expand the storage capacity of components within the set space without impairing workability when taking out components. Moreover, it is an object of the present invention to provide an excellent integrated parts shelf that can reliably prevent mistakes in taking out parts when taking out parts, thereby benefiting fields in which parts supply technology is used in various industries.

<Means for solving the problem> In order to solve the above-mentioned problem, the structure of this invention, which is based on the above-mentioned claims for utility model registration, is based on the above-mentioned object, in which a plurality of carrier racks are installed in steps on the side frame. A carrier frame on which a plurality of parts boxes are movably placed is installed tilting forward on each carrier rack, and a stopper plate for locking the frontmost parts box is disposed in front of the carrier frame. In the integrated parts shelf, each of the carrier racks is equipped with a slide base that is slidable in the front and back direction and a forward/backward movement device, and the slide base is provided with the stopper plate and is linked to the forward/backward movement device, and the slide base is provided with the stopper plate and is linked to the forward/backward movement device, and the slide base is provided with the stopper plate and is connected to the forward/backward movement device. A stopper device is equipped with another stopper plate, which is shaped like a downward flat plate and has a tapered surface that comes into contact with the parts box, and an air cylinder at the rear of the stopper plate. A technical measure is taken in which a link arm is provided to lift the front part onto the tapered surface of the stopper plate.

<Function> Then, the carrier frame, in which a plurality of parts boxes are movably placed on each of the carrier racks installed in steps on the side frame, is tilted forward and set. A slide base that can be slid in any direction and an advancement/retraction device are provided to move the slide base, and a stopper plate is provided at the front end of the slide base to move a plurality of component boxes back and forth on the carrier frame of each carrier rack. After sequentially placing the parts boxes next to each other, the frontmost parts box can be slidably advanced relative to the slide base by activating the advancement/retraction device in which the desired parts box is located. is equipped with a stopper device for the subsequent parts box,
When the frontmost parts box slides forward due to the operation of the advancing/retracting device, the front part of the succeeding parts box is lifted by the stopper device and brought into contact with the lower tapered surface of the other stopper plate. When the parts are removed from the frontmost parts box, the frontmost parts box is returned to its original position by the advancing/retracting device, and the front parts box is emptied. When removed, the stopper device is released, thereby reliably preventing unloading errors.

<Example> Next, an example of this invention will be described below based on FIGS. 1 to 4. Incidentally, the same parts as those in the conventional mode shown in FIG. 5 will be described using the same reference numerals.

Reference numeral 5 denotes an integrated parts shelf which forms the gist of this invention, and is constructed by constructing a framework in which carrier racks 2 are installed vertically in steps at predetermined pitches on a predetermined number of side frames 1 running in the vertical direction. is formed.

Brackets 6, 6' are installed at predetermined portions of the carrier racks 2 disposed in the longitudinal direction of each stage.
A carrier frame 3, 3 having rollers 7, .

In addition, the carrier rack 2 running in the longitudinal direction...
is assembled in advance so as to be inclined slightly forward with respect to the side frame 1, and therefore, the carrier frames 3, 3 are arranged along the carrier rack 2, which is disposed in the front and back direction. It will be erected.

Further, a U-shaped bracket 9 having a notch 8 is fixed to the lower surface of the front end of the carrier rack 2, and the tip of a guide rod 11 inserted into an air cylinder 10 serving as an advancing/retracting device is attached to the bracket 9. The proximal end of the guide rod is fixed to the front side of the bracket 6.

Then, the cylinder body 1 of the air cylinder 10
2 is fixed to a slide base 13 whose upper surface is flat, and the tip of the slide base 13 is loosely inserted into the notch 8 of the bracket 9, and the stopper plate 4 is integrally attached to the tip. It is curved and extended.

Therefore, since the leading and rear ends of the guide rod 11 are fixed to the brackets 9 and 6, the cylinder body 12 is moved forward and backward integrally with the slide base 13.

The base end of an air cylinder 14 is supported by a pin on the upper surface of the bracket 6', and a rod pin 15 is interposed between the carrier frames 3 in front of the bracket 6'. The center portion of the link arm 16 is pivotally supported at the center portion of the rod pin 15, and the base end portion of the link arm 16 is connected to the piston rod 17 of the air cylinder 14.
A rod 18 of a predetermined length is pivotally supported horizontally at the tip of the link arm 16.

Then, the piston rod 1 of the air cylinder 14
When the link arm 7 is moved forward or backward, the link arm 16 appropriately pivots around the rod pin 15, and the tip of the link arm 16 moves up and down.

Further, 19 is a flat stopper plate having a tapered surface 20 on the lower side, and is fixed to the rear surface of the central part of the bracket 6, and is connected to the air cylinder 14 and
Together with the link arm 16, a stopper device 21 is configured.

In addition, parts boxes 22, 2 placed on carrier frames 3, 3 are placed at appropriate locations on the carrier rack 2.
A limit switch (not shown) is attached to check the existence of air cylinder 1.
0 is connected to a command device (not shown), and the air cylinder 14 is connected in conjunction with the limit switch.

Furthermore, in the above description, one unit storing the same type of component boxes 22, 22' has been described, but in reality, completely similar units are provided in multiple stages and rows in the vertical and horizontal directions.
Different types of parts boxes 22, 22' are stored in each unit.

In the above-mentioned configuration, a plurality of component boxes 22, 22', . Preparations for carrying out the work are completed.

First, before an operator starts to take out parts, a limit switch (not shown) provided on each carrier rack 2 is activated to remove parts from the parts boxes 22 and 2.
2' is confirmed, and when this is confirmed by the limit switch, the air cylinder 14 connected to the limit switch is operated, and its piston rod 17 is extended to move the link arm 16 to the rod pin 15. The tip of the link arm 16 and the rod 1
8 and raise the front part of the succeeding parts box 22' as shown in FIG.

In this way, when the front part of the following product box 22' is lifted, the lifted upper end comes into contact with the tapered surface 20 of the upper stopper plate 19, and as a result, the corresponding The subsequent parts box 22' and the subsequent parts box (not shown) are prevented from sliding on the slope of the carrier frames 3, 3 due to their own weight.

Next, in this state, the air cylinder 10 is operated by a command device (not shown), and the cylinder body 12 moves forward along the guide rod 11 together with the slide base 13.

Then, the stopper plate 4 that was locking the parts box 22 at the frontmost part moves forward at the same time, so the parts box 22 at the frontmost part is pushed against the carrier frame 3 by its own weight.
It slides on the slope of the carrier frame 3, and finally comes forward from the front end of the carrier frame 3, as shown in FIG.
The front end thereof is inclined and comes into contact with the upper surface of the slide base 13.

Then, the cylinder body 12 of the air cylinder 10
When the parts box 22 advances to the frontmost part, the parts box 22 at the frontmost part stops with its upper opening tilted forward at a predetermined angle, and in this state, the operator takes out a part from the part box 22, not shown. Press the completion button to send a completion signal to the command device.

Then, the command device issues an instruction signal to the air cylinder 10 again, and the air cylinder 1
0 retreats the cylinder body 12 together with the slide base 13 and parts box 22 to the original position.

Therefore, the subsequent parts boxes 22' are connected with a space of one box between them.

In this way, the command device sequentially sends signals in accordance with predetermined production instructions, and the worker takes out the parts from the pushed-out parts box.

This series of operations is repeated several times, and when the front parts box 22 is empty, the operator removes the parts box 22 and then moves the slide base 1.
3 is returned to its original position, the air cylinder 14 connected in conjunction with the limit switch operates its piston rod 17 in the retracting direction.

In this case, when the air cylinder 14 retracts the piston rod 17, the link arm 16 connected to the piston rod 17 pivots its tip around the rod pin 15 and lowers the piston rod 17, thereby lowering the piston rod 17. The stopper function for the box 22' is released, and the subsequent parts box 22' slides on the slope of the carrier frames 3, 3 to the position where the preceding parts box 22 was located.

Then, the parts boxes (not shown) following the parts box 22' move forward in the same way to the position where the parts box 22' was located, the presence of each is confirmed by the limit switch, and the parts boxes following the parts box 22' are moved forward. The box is stopped by the stopper device 21, and the same operations as those described above proceed.

In this way, there is no mistake in taking out each part, and parts are taken out exactly as instructed.

It goes without saying that the embodiment of this invention is not limited to the above-mentioned embodiments. For example, the advancing/retracting device and the stopper device installed on the carrier rack are not limited to air cylinders, and other actuators may be used. Various aspects such as the above can be adopted.

<Effects of the invention> As described above, this invention has the excellent effect of being able to reliably expand the parts storage capacity in a limited space without impairing workability when taking out parts. is played.

That is, each carrier rack is equipped with a slide base that can freely slide in the front and back direction and a forward/backward movement device, and the slide base is provided with a stopper plate for locking the parts box at the forefront and is linked to the forward/backward movement device. As a result, the frontmost parts box placed on the carrier rack is projected and tilted by the forward movement of the slide base and stopper plate by the advance/retreat device, and the worker can take out the parts in the projected state. When the parts have been taken out, the slide base and stopper plate can be returned to their original state by retracting the slide base and stopper plate using the advancing/retracting device.As a result, it is necessary to provide a space between the vertical carrier racks for taking out the parts. The effect is that the parts storage capacity can be increased by that amount.

Furthermore, by equipping the carrier rack with a stopper device for the subsequent parts box,
When the front parts box moves forward or backward together with the slide base and stopper plate,
There is no need for unnecessary loads to be applied from subsequent parts boxes, and the effect is that the parts boxes can be smoothly extended and retracted.

In addition, since the operator takes out parts one by one from the parts box that protrudes forward with the slide base and stopper plate, it is possible to reliably take out the desired parts without making mistakes. Excellent effects are produced.

Furthermore, the pitch between the carrier racks in the vertical direction can be narrowed, and unnecessary gaps between the parts boxes and the carrier racks can be almost eliminated, making it easier to block both sides of the integrated parts shelf with obstacles and insert parts boxes. By providing a door with a lock on the side, it is possible to prevent theft of parts, and it also has the effect of improving heat retention efficiency when heating parts in cold weather. .
