Description

[Detailed Description of the Invention] This invention relates to an article conveying device that supplies a predetermined amount of articles to a location at a constant height.

Conventionally, there have been many devices for transporting small articles such as workpieces from a low place to a high place between machines on a production line.

However, there is no device for feeding a fixed amount of workpieces to the conveyance device, and it has not been possible to alleviate the decrease in production caused by the difference in machining ability between the machines.

Furthermore, there is no system that utilizes the driving force of a conveying device to that of a stationary device, resulting in a complicated structure.

Therefore, in view of the above circumstances, this invention opens and closes the supply port of the storage tank that stores the workpiece in relation to the vertical movement of the packet of the transport device, and takes out a certain amount of the workpiece from the storage tank into the packet. This is transported to a high place in a packet and automatically supplied to the desired high place.

Hereinafter, this invention will be described in detail based on an embodiment shown in the accompanying drawings.

FIG. 1 shows an outline of an embodiment of this invention.

A guide frame 3 is vertically fixed on the substrate 1 for vertically guiding a packet 2 for transporting articles, and a storage tank 4 for storing workpieces is fixed near the guide frame 3. It is set up.

Then, the packet 2 at the bottom position of the guide frame 3 (
A cutting chute 6 is provided between the supply port 5 of the storage tank 4 (represented by a two-dot chain line in FIG. 1) and the supply port 5 of the storage tank 4.

Next, the vertical movement of packet 2 and the loading/unloading mechanism are set to the second stage.
This will be explained with reference to FIGS. 6 to 6.

The guide frame 3 has a linear cross-section and has vertical grooves 7 along its entire length, and a motor 8 is fixedly installed on the lower rear surface.

The output shaft 9 of this motor 8 is projected into the concave cross section of the guide frame 3, the driving sprocket 10 is fixed, and the driven sprocket 11 is rotatably attached to the upper part of the concave cross section of the guide frame 3. A chain 13 is hung endlessly between the sprocket 11 and the driven sprocket 11, and the chain 13 is circulated in the same direction by driving the motor 8.

The pin 14 is fixed to one location of the chain 13 in a horizontal cantilevered manner, and is fitted into a horizontal elongated groove 16 of the attachment 15, and circulates as the chain 13 circulates.

The attachment 15 is guided within the concave cross section of the guide frame 3 by a guide roller 17 attached to the side.
It moves up and down within the guide frame 3.

Furthermore, a packet holder 18 is attached to the attachment 15 in order to improve the stability of the packet 2 when the packet 2 moves up and down.

A packet reversing shaft 19 is attached to this packet holder 18, on which the packet 2 is rotatably supported, and a spring 2
0 is compressed between the bottom outer surface of the packet 2 and the packet holder 18.

In addition, a stopper 21 is protruded from the upper side of the guide frame 3, and a locking piece 22 that engages with the stopper 21 is fixed to the rear side wall of the waist packet 2. When the waist packet 2 rises, the locking piece 22 is attached to the stopper 21. When they collide, the packet 2 tilts its opening downward against the spring 20 to eject the accommodated workpiece, and when the stopper 21 and the locking piece 22 are disengaged, the packet 2 is moved by the biasing force of the spring 20. Returns to horizontal position and stabilizes.

23 is a chute for carrying out articles.

Next, the cutting and distributing chute 6 and its related mechanisms are installed in the seventh
This will be explained with reference to Figures A and Bi and Figure 8.

The lower side of the storage tank 4 is cut out over its entire width as shown in the figure, and this portion is used as the supply port 5.

In order to ensure the supply of workpieces from the supply port 5, the bottom of the storage tank 4 is sloped, and side plates 24 are extended from both sides of the supply port 5.

A cutting fixed distribution chute 6 is fitted in front of the supply port 5 and between the side plates 24, and a rotating shaft 25 protruding outward from the middle part of the side wall of the cutting fixed distribution chute 6 is connected to the storage tank 4.
It is rotatably supported on a support frame 26.

The cutting and distributing chute 6 receives a certain amount of the workpiece in the storage tank 4 when the packet 2 is located above the lowest position by more than a set distance in the state shown in FIG. 7A,
In the state shown in FIG. 7B, that is, when the packet 2 is at the lowest position, a certain amount of the workpiece is transferred into the packet 2, and during this period, the outflow of the workpiece from the supply port 5 of the storage tank 4 is prevented. is being prevented.

The cutting and distribution chute 6 is connected to the supply port 5 of the storage tank 4 in the state shown in FIG. 7A, and has a receiving plate 28 for receiving a certain amount of workpieces in the storage tank 4, and a receiving plate 28 in the state shown in FIG. 7B. Packet 2
It consists of a bottom plate 27 for supplying the workpieces into the storage tank 4, and an arcuate bent plate 29 for preventing the workpieces from flowing out from the supply port 5 of the storage tank 4 between them.

Note that 27' is a side plate extending upward from both sides of the bottom plate 27.

A return spring 30 is compressed between the rear part and the base end 1 of the cutting and distributing chute 6, and an adjustable stopper 31 is screwed to the front end of the support frame 26 to restrict the return rotation of the cutting and distributing chute 6. do.

In addition, the front lower surface of the cutting fixed distribution chute 6 is connected to a direct connection rod 34.
It is connected to a movable slide 33 that is slidably fitted onto a guide rod 32 that is vertically fixed to the base plate 1.

Note that the length of the connecting rod 34 is adjustable, and the connecting portion is rotatable.

Due to the above structure, when the packet 2 is located above the lowest position as shown in FIG. 7A, the cutting and distributing chute 6 is always in an upright state by the return spring 30.

By the way, one end of the movable slide 33 is within the movement locus of the drive transmission member 35 fixed to the packet holder 18 of the packet 2. Therefore, near the end of the downward stroke of the packet 2, the drive transmission member 35 is moving slide 33
Thereafter, as the packet 2 moves downward, the movable slide 33 is pushed down, and the cutting and distribution chute 6 is moved through the connecting rod 34 against the elasticity of the return spring 30 as shown in FIG. 7A.
It is tilted from the state shown in FIG. 7 to the state shown in FIG. 7B.

Further, the upward stroke of the movable slide 33 along the axial direction of the guide rod 32 is regulated by the contact position between the stopper 31 and the abutting plate 36 extending from the base end of the cutting and fixed distribution chute 6 toward the rotating shaft 25. The movable slide 33, which is released from the pressed state by the rise of the drive transmission member 35 attached to the packet 2, is rotated by the tensile force of the return spring 30 to a position where the abutment plate 36 abuts the tip of the stopper 31. It rotates counterclockwise around the moving shaft 25 as the rotation center.

Here, the length of the guide rod 32 along the axial direction is adjusted in advance so that the movable slide 33 does not come off the guide rod 32 at the end of the ascending stroke of the movable slide 33.

On the other hand, at the end position of the upward stroke of the movable slide 33, the workpiece discharge end of the cutting and distributing chute 6 is
As shown in FIG. 7A, the packet 2 moves to a position deviated from the movement trajectory of the packet 2 by the rotational movement about the rotation axis 25.

Therefore, the upward movement of the packet 2 causes the cut-out fixed distribution chute 6
will not be disturbed by.

The operation of this device will be explained.

In the state shown in Fig. 7 (Fig. 5), the cutting distribution chute 6
A certain amount of workpieces accommodated in the packet 2 are loaded into the packet 2.

Subsequently, the packet 2 is raised via the chain 13, the bin 14, and the attachment 15 by the drive of the motor 8.

As the packet 2 rises, the drive transmission member 35 provided on the packet holder 18 rises, and accordingly, the tip of the cutting and distributing chute 6 is lifted upward by the elasticity of the spring 30. As shown in FIG. 7A, the supply port 5 of the storage tank 4 and the receiving plate 28 of the cutting and distributing chute 6 communicate with each other.

On the other hand, as the packet 2 approaches the rising end as shown in FIG. 6, the locking piece 22 of the packet 2 collides with the stopper 21 and is reversed in the A direction to discharge the workpiece to the unloading chute 23.

When packet 2 starts descending from the rising end, spring 2
0 returns to direction B and further descends.

When the packet 2 continues its downward movement from the state shown in FIG. The fixed distribution chute 6 is rotated so that the tip thereof faces downward against the biasing force of the return spring 30.

At this time, a certain amount of the workpiece stored in the cutting and distribution chute 6 is thrown into the packet 2, and the supply port 5 of the storage tank 4 is closed with the arc-shaped bending plate 29.

After that, repeat the above operation.

As mentioned above, this device is a device that automatically conveys a fixed amount of articles from a low place to a high place, and is guided by an upright guide frame and moves up and down by an endless chain drive. a storage tank for storing articles and having a supply port at the bottom; a storage tank rotatably provided between the packet at the lowest position of the guide frame and the supply port of the storage tank; At the time of carrying out, an arcuate bending plate is provided on the rear upper surface which rotates forward and closes the supply port of the storage tank, and a constant return spring rotates backward to remove a certain amount of goods from the supply port of the storage tank. and a fixed cutout chute configured to receive the packet, and configured to cause the cutout fixed distribution chute to rotate forwardly against the return spring when the packet is lowered to the lowest position. This device is capable of automatically transporting a fixed amount of workpieces from a low place to a high place between machines on a production line, and the distribution device can also be operated by the vertical driving force of the packet, resulting in a simple structure. .

Next, differences in process power of the production line can be absorbed.

Furthermore, the conveyance from the pre-process outlet chute to the machine entrance parts feeder can be automated, making it possible at low cost.
