Description

[Detailed Description of the Invention] The present invention relates to a supply device that supplies square pipes that have been transferred onto a manbo by stacking them to the next process.

Conventionally, there was no suitable equipment for supplying square pipes to the line, so everything was done manually.

For this reason, it was unsafe, and at the same time, no improvement in efficiency could be expected, creating a bottleneck in the work process.

In addition, conventionally, three workers were required to supply the square pipes, including the operation of the next process line, which was also a problem in terms of labor saving.

Conventionally, devices are known that automatically depalletize items loaded on ordinary pallets.Since the pallets themselves are small, the conveyor on which the pallets and items are placed is moved up and down to stack the items on the pallets one layer at a time. rain is being carried out.

However, there is no known device for processing items such as long square timbers that cannot be stacked on small pallets, and manual work is required as described above.

It is an object of the present invention to solve the above-mentioned problems and provide a supply device that safely and efficiently supplies square pipes stacked on a manbo to the next process.

The details of the present invention will be explained with reference to embodiments shown in the figures.

In FIGS. 1 to 3, square pipes 1 are stacked on a cart 3 with a manbo 2 interposed therebetween.

The trolley 3 has wheels 4, is guided by rails 5, and is reciprocated between loading and unloading positions by suitable drive means.

As the driving means, for example, a conveyor chain 7 driven by a truck drive motor 6 is used, and the truck 3 is pulled by a locking member 8 provided on the conveyor chain 7.

A rear end detection member 9, for example, a limit switch, detects when the trolley 3 reaches the loading position during reciprocation, and a front end detection member 10, for example, the limit switch 4, is provided for detecting that the trolley 3 reaches the loading/unloading position.

Lifter v1 is located at the loading/unloading position for loading and unloading square pipes from trolley 3.
will be provided.

The lifter 11 is raised and lowered by suitable drive means.

As the driving means, for example, a ball screw 13 driven by a lifter motor 12 is used.

Of course, for example, a hydraulic motor or the like may also be used.

At the loading/unloading position, the square pipe 1 on the truck 3 is lifted up by a lifter 11 passing through the truck 3.

Fork insertion level detector 14 when the square pipe 1 rises;
For example, the upper end of the rising square pipe is detected by a phototube, and the lifter 11 is stopped.

Therefore, as the square pipes are loaded and unloaded, the lifter 11 for one stage of square pipes is raised.

A fork device 15 for loading and unloading square pipes lifted by a lifter 11 includes a fork 16, a transfer device 17 that supports the fork 16, and a pedestal 18 that supports the transfer device 17.

The transfer device 1T has wheels 2 driven by a transfer motor 19.
0 is guided by rails 21 provided on the pedestal 18.

The pedestal 18 includes a first detector 22 and a second detector 23 for detecting the standby position, loading/unloading position, and supplying position of the transfer device 17, respectively.
A third detector 24, for example a limit switch, is provided.

The square pipe 1 loaded and unloaded from above the lifter 11 by the fork device 15 is lowered onto the waiting table 25.

The standby table 25 is formed to be able to be raised and lowered, and a raising and lowering means 26 is provided.
For example, it is moved up and down by an air cylinder.

A conveyor belt 27 is arranged between the waiting tables 25.

The conveyor belt conveyor 27 is driven by a drive motor 28.

The square pipes sent by the conveyor belt conveyor 27 are sent one after another to the next process in a vertically lined state by the vertical feed conveyor 29.

The operation of this device is as follows.

Square pipes 1 are loaded in a stacked manner on a cart 3 by a crane using a manbo 2 at a loading position.

Next, when the automatic start button is pressed, the cart drive motor 6 is driven and the cart 3 is moved.

The truck 3 is stopped at the loading/unloading position by the operation of the front end detection member 10.

At the same time, the lifter lifting motor 12 is driven and the lifter 1
1 passes through a through hole 30 formed in the truck 3 and rises.

The square pipe 1 on the trolley 3 is transferred onto the lifter 11 and raised.

The square pipes 3 are stacked with the manbo 2 forming an interval large enough to allow the claw 16a of the fork 16 to be inserted.

When the square pipe 3 rises, the fork insertion level detector 14
The lifter 11 is stopped at the same time that the square pipe 3 at the uppermost end passes and the distance between the square pipes 3 is detected.

At the same time, the transfer motor 19 is activated, the transfer device 17 is moved from the standby position, and the fork 1 carried by the transfer device 17 is moved.
6 is inserted under the square pipe 1 at the uppermost end.

The transfer device 17 activates the second detector 23 at the loading/unloading position and stops.

Simultaneously with the activation of the second detector 23, the lifter 11 descends.

At this time, the top square pipe is left on the pawl 16a of the fork 16.

The lifter 11 is stopped by actuating a lower end detector 31, such as a limit switch.

Activation of the lower end detector 31 causes the transfer device 17 to advance, activate the third detector 24, and stop at the supply position.

At the same time, the standby table 25 is raised by the operation of the elevating means 26, and the square pipe 1 on the fork pawl 16a is transferred onto the standby table 25.

The standby table 25 is stopped by the operation of the rising edge detector 32.

At the same time, the transfer device 17 is moved backward by the reverse operation of the transfer motor 19, and stopped by the operation of the first detector 22, and the fork 16 returns to the standby position.

During this time, the standby table 25 is lowered and stopped at the original position by the operation of the original position detector 33.

While the standby table 25 is lowered, the square pipe 1 placed on the standby table 25 is transferred onto the conveyor belt conveyor 27.

The square pipe 1 is transported by a transport belt conveyor 27,
It hits the stopper 34 and stops.

The stopped square pipes 1 are pushed up one by one by a kicker 35 that moves up and down and are fed to a vertical conveyor 29 by a chute 36.

The kicker 35 is activated when the detector 37 confirms that the square pipe 1 is present.

The conveyor belt conveyor 27 can be driven continuously or can be driven in an inching manner in accordance with the supply to the vertical conveyor 29.

By repeating the above operations, the square pipes 1 on the lifter 11 are sequentially supplied to the vertical conveyor 29.

Every time the square pipe 1 is transferred from the lifter 11 for one stage to the fork 16, the manbo 2 used for stacking the square pipes is manually removed.

When the lifter 11 moves up the square pipe at the lowest stage, the upper limit detector 38 detects the lid 11 and detects the completion of supply.

Upon detection of supply completion, the lifter 11 moves to the through hole 30 of the trolley 3.
When the trolley 3 is lowered to the standby position, the trolley 3 moves backward and stops when detected by the rear end detection member 9, and the next square pipe is loaded by the crane.

The present invention provides a feeding device with a simple structure and reliable operation.

This invention enables safe and efficient work, and allows one worker to do the work, saving labor.

In the embodiment, the supply of square pipes has been described, but the present invention is not limited to square timbers, and can be widely used for conveying and supplying objects that cannot be rolled.
