Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a reciprocating conveyor device used for conveying articles between two fixed locations.

Conventionally, the following two methods have been used to transport articles between two fixed locations.

One of them is to attach a jig to place the article on a self-propelled device that has a drive source such as an electric motor or an air motor, and to supply electricity or air to the drive source.

It is a self-propelled device that runs on fixed rails.

Another method is to run a jig that is movably supported on a fixed rail and is pulled by a fixed drive source via a chain or something similar.

However, although the above-mentioned conventional devices are simple in operation, they have the disadvantage that they require a lot of work, and that the speed of conveyance cannot be increased, resulting in a long conveyance time.

Further, in order to shorten the time for transporting articles, it is preferable to use a variable speed drive source, but this has the problem of making the device expensive.

In view of the above, this invention can shorten the transport time when transporting articles between two locations.

It is an object of the present invention to provide a conveyance device that can be operated with a simple mechanism.

Next, this invention will be explained based on embodiments shown in the drawings.

In the figure, the support member 1 is attached at its upper end to a beam Gz, which is a ceiling structural member attached to a ceiling C or the like of a factory.

The lower end of the support member 1 is tapered, and the tip thereof is an arcuate portion 1a.

The rail member 2 has a square-shaped cross section, and a bifurcated hanging fitting 3 is fixed to the upper surface of the central portion thereof.

The rail member 2 is attached to the support member 10 by the hanging fitting 3.
It is swingably attached to the support member 1 via a pivot 4 attached to this part with the part a sandwiched therebetween.

Article suspension device 5 (hereinafter referred to as trolley).

), two wheels 7 supported by the lower plate 2a of the rail member 20 are pivoted 8 to U-shaped hanging members 6 on each side of the rail member 20.

Further, a hanging fitting 9 is attached to the hanging member 6 in a hanging manner at the center of its lower part.

The positioning device 10 has a plate-shaped stopper 11.

This stopper 11 has a fan shape, and has a small arc portion 1 on the negative side.
1a has a large arc portion 11b on the other side, and the large arc portion 11b
An arcuate groove 11c is provided in the groove 11c.

The support 12 is fixed to the upper surface of the rail member 2 near the right end.

A stopper 11 is attached to one side of a rotation shaft 13 which is pivotally attached to a support 12 so that its small arc portion 11a can swing (see FIG. 4).

A swing lever 14 is fixed to the other side of the rotation shaft 13, and a pin 16 that engages with the arcuate groove 11cc of a stopper 110 is attached to the tip of an arm 15 fixed at a substantially right angle to the swing lever 14. It is fixed.

The second support 17 is attached to the upper surface of the rail member 2 on the side closer to the support member 1 than the support 12 .

The second support 17 has an Lm lever 18 (hereinafter referred to as L lever).

) is pivotally attached 19 so that it can swing, and the L lever 1
The second lever 18a (on the right side in the figure) of the second lever 18a and the swinging lever 14 are connected to each other while maintaining parallelism through a connecting bar 20 and pins 21 and 22 attached to both ends of the connecting bar 20. .

In the positioning device 10 formed as described above, the stopper 11 is held by its own weight and rotates clockwise around the rotation shaft 13, so that the pin 16 at the tip of the arm 15 is always on the upper edge of the arcuate groove 11c. At the same time, the lower end of the large arc portion 11b of the stopper 11 is located below the upper end of the wheel 7 of the trolley 5.

The first positioning device 10 is the other second positioning device of the L lever 18.
When the lever 18b is pushed down, the L lever 18
Rotate counterclockwise around 9.

The connecting bar 20 moves toward the support member 1 side.

As a result, the swing lever 14 rotates counterclockwise around the pivot shaft 13, and the arm 15 fixed to the swing lever 14 also rotates in the same direction, so that the pin 16 at the tip of the arm 15 rotates in the same direction. Rotate the stopper 11 counterclockwise.

Therefore, the lower end of the large arc portion 11b of the stopper 11 is located at a higher position than the upper end of the wheels 7 of the trolley 5.

The positioning device 10' is attached to the rail member 2 at a position symmetrical to the positioning device 10 with respect to the support member 1, and each component of the positioning device 10' is a stopper 11' and a swing lever 14'.

The L lever 18' etc. are the stopper 11 of the positioning device 10.
．． It is formed in a symmetrical shape with respect to the swing lever 14, the L lever 18, etc., and the support member 1.

The press member 23 has its upper end attached to the beam G above the L lever 18, and the press plate 23a at its lower end is located above the second lever 18b of the L lever 18.

The holding member 23' is also attached at its upper end to the beam G above the L lever 18', and the holding plate 23'a at its lower end is connected to the second lever 18'b of the L lever 18'.
It is located above.

The upper support 24 is attached to the beam G between the support member 1 and the presser member 23.

An air cylinder 25 with a piston 25a is connected to the upper support 24 by a pin 26.

Below the air cylinder 25 is a lower air cylinder 27 having a piston 27a connected to the piston 25a of the air cylinder 25.
is a lower support 2 attached to the upper surface of the rail member 2.
8 and a pin 29.

The upper air cylinder 25 is a positioning device 1 for the rail member 2.
0 side (hereinafter referred to as the right side).

), and the lower air cylinder 27 is operated on the positioning device 10' side (hereinafter referred to as the left side) of the rail member 2.

) is activated when the vehicle is raised.

The first switch 30 is attached to the rail member 2 between the hanging fitting 3 and the lower support 28, and when the trolley 5 passes from the right side to the left side, the first switch 30 detects the trolley 5 and switches it to the upper air cylinder 25. A signal is sent to operate the air cylinder 25 to make the rail member 2 horizontal.

A second switch 31 is attached to the rail member 2 on the side opposite to the first switch 30 with respect to the hanging fitting 3.

When the trolley 5 moves from the left side of this switch 31 to the right side, the second switch 31 detects the trolley 5 and sends a signal to the lower air cylinder 27.
to make the rail member 2 horizontal.

Note that 32 is a right end stopper of the trolley 5 fixed to the right end of the rail member 2, and 33 is a left end stopper fixed to the left end of the rail member 2.

Next, the operation of the reciprocating conveyance device having the above configuration will be explained.

In the following description, the 1 positioning device 10 side will be described as the article carry-out side, and the positioning device 10' side will be described as the carry-in side.

Neither the upper air cylinder 25 nor the lower air cylinder 27 operates, so the rail member 2 is horizontal, and the trolley 5 is at the stop 1 of the positioning device 10.
One worker attaches the article W to the hanging fitting 9 of the trolley 5 in a state on the right side of the trolley 5.

Next, when one worker operates a push button (not shown) to operate the upper air cylinder 25, the piston 25
a rises, and the rail member 2 tilts upward to the right about the pivot 4.

Therefore, after the second lever 18b of the L lever 18 that has risen comes into contact with the presser plate 23a of the presser member 23, this presser plate 2
Pushed down from 3aK.

Due to this. Since the L lever 18 rotates counterclockwise around the shaft 19 to move the connecting bar 20 to the left, the swinging lever 14 connected to the connecting bar 20 by a pin 21 rotates around the rotating shaft 13. (See Figure 5).

Therefore, the arm 15 fixed to the swing lever 14 also rotates counterclockwise, and the pin 16 at the tip of the arm 15 rotates the stopper 11 counterclockwise around the rotation shaft 13, causing the stopper 110 The lower end of the thick arc portion 11b is connected to the trolley 5
move it to a position higher than the top of the wheels 7.

As the stopper 11 rotates in this manner, the trolley 5 is disengaged from the stopper 11.

Each wheel 7 begins to roll to the left on the inclined lower plate 2a of the rail member 20.

In this way, when the trolley 5 that has moved to the left passes below the first switch 30 and the first switch 30 detects the trolley 5, the piston 25a of the upper air cylinder 25 returns to its initial position. The rail member 2 becomes horizontal.

When the rail member 2 becomes horizontal, the trolley 5 moves to the left while its running speed is reduced due to the friction between each wheel 7 and the lower plate 2a of the rail member 20, and the trolley 5 moves to the left by the positioning device 10'.
The left wheel 7 collides with the stopper 11'.

Since the stopper 11' has an arcuate groove 11'c, even if the pin 16' is stationary, the stopper 11' is pushed up by the wheels 7 and rotates clockwise, so the trolley 5 is further decelerated by the stopper 11'. After passing through the stop flange 11', it comes into contact with the left end stopper 33 and stops.

On the other hand, when the trolley 5 passes, the stopper 11' rotates counterclockwise due to its own weight.

The trolley 5 is fixed in this position.

The worker is located at the left end of the rail member 2.

The article W transported by the trolley 5 that has arrived as described above is removed from the hanging fitting 9 of the trolley 5, and the lower air cylinder 2 is moved by operating a push button (not shown) or the like.
7, the piston 27a rises, rotates the rail member 2 clockwise about the pivot 4, and tilts it downward to the right.

As a result, the trolley 5 located at the left end of the rail member 2 arrives at the right end of the rail member 2 in the same manner as when moving from right to left.

In the above embodiment, when the trolley 5 runs on the rail member 2, the speed increases as the trolley 5 advances due to the action of 1 gravity when the trolley 5 moves by itself and descends on the inclined rail member 2.

Further, when the trolley 5 moves on the horizontal rail member 2, its speed gradually decreases due to frictional resistance with the rail member 2.

Therefore, the trolley 5 performs variable speed movement on the rail member 2, and the time required to travel on the rail member 2 is reduced compared to conventional constant speed movement.

As described above, this conveying device can convey articles from either the left or right direction.

As described above, this invention uses a rail member having a predetermined length that is swingably attached to a support member attached to a ceiling structural member, etc., to transport an article between two locations. , a suspension device for an article supported by the rail member so as to be able to travel in its longitudinal direction; and a suspension device for an article supported by the rail member so as to be able to run in its longitudinal direction; and by tilting the rail member, the suspension device is caused to travel by its own weight, and by returning the inclination to the original position, the article is suspended at the conveying end of the rail member. A swing mechanism for a rail member that decelerates the device.

are respectively attached near both conveying ends of the rail member, and are capable of fixing the suspension device when the rail member is horizontal;
By incorporating a positioning device that releases the fixation of the suspension device as the rail member inclines, the suspension device itself is self-propelled and does not require a device to drive it, simplifying the structure of the transportation device. Furthermore, when the rail member is inclined, the suspension device moves faster, and at the conveying end, the rail member becomes horizontal and the moving speed becomes slower, so that the moving time of the suspension device can be reduced compared to the conventional method.
