Description

[Detailed Description of the Invention] There are various devices for transferring bars, etc. on a skid to a cradle, but all conventional devices
Since the bars and the like were dropped into the cradle with a considerable height, if the bars were heavy, they would make a loud impact sound and the bars would be damaged.

The present invention relates to a transfer device for bar materials, etc., which eliminates the above-mentioned drawbacks, and will be specifically described below based on an embodiment shown in the attached drawings.

In Fig. 1, reference numeral 1 denotes a cart that is driven back and forth on rails 2 laid on the floor by a telescoping actuator 3 powered by hydraulic pressure, etc., and a column 4 is erected at its rear (right side in Fig. 1). It is set up.

A cam piece 7 is fixed to the front surface of the upper end of the support column 4. The cam piece 7 has a vertical front surface 5 and an inclined surface 6 extending rearward and downward at the lower end thereof.

At the front and rear of the pillar 4 are screw rods 8 that are parallel to the pillar 4.
is pivotally installed, and its lower end is linked to a motor 9 installed at the rear of the upper surface of the truck 1 via a speed reduction device 10.

Reference numeral 11 denotes a transfer tool, which includes a plurality of rollers 12 on the support column 4.
A receiving arm 11b facing forward is connected to the upper part of the lifting cylinder 11a, which is fitted to the outside so as to be able to rise and fall freely through the upper part of the lifting cylinder 11a. Furthermore, a detection plate 13 is attached to the lower surface of the receiving arm 11b.

Nut 1 fixed to the rear surface of the elevating cylinder 11a
4 is screwed into the screw rod 8, and when the screw rod 8 is rotated by the motor 9, the loading device 11 moves up and down.

As shown in FIG. 2, at the front end of the receiving arm 11b,
A tilting stopper 15 is pivotally connected by a horizontal pin 16 slightly above its lower end, and a tilting rod 17 facing rearward is attached to the lower end of the stopper 15.
The front end of is pivotally mounted. The rear surface of the upper end of the stopper 15 is an inclined surface 15a directed downward and rearward.

The central part of the tilting rod 17 has a support plate 18,
It is supported by the receiving arm 11b so as to be able to rotate slightly around the horizontal axis, and at the rear end of the tilting rod 17,
A roller 19 facing left and right is pivotally installed.

The tilting rod 17 is biased rearward by a compression spring 20 fitted to the tilting rod 17 on the rear side of the support plate 18 . When the transfer tool 11 is at the upper limit, the roller 19 moves against the vertical front surface 5 of the cam piece 7.
In order to make contact with
Projects upward from c. When the transfer tool 11 is lowered, the lever 17 retreats, the roller 19 presses against the front surface of the support column 4 via the inclined surface 6 of the cam piece 7, and the stopper 15 falls forward and its The inclined surface 15a is directed upward.

Reference numeral 21 denotes a fixed skid provided at the upper end of the support column 4, facing in the front-rear direction and parallel to each other. Reference numeral 22 denotes a pair of left and right cradles having a U-shaped side surface and installed at the lower front of the skid 21 with a space between them. , an escape groove 23 facing in the front-rear direction is formed. At the bottom of the escape groove 23, the inclined edge 11c of the receiving arm 11b of the transfer tool 11 is formed.
When it descends below the bottom of the cradle 22,
A lower limit plate 24 is provided to which the detection plate 13 of the receiving arm 11b comes into contact.

FIG. 1 shows that the device described above has been raised to the upper limit, and a plurality of round bars 25, which have been transferred to the front end of the skid 21, are supported by an appropriate device with the inclined edge 11 of the receiving arm 11b, and This shows the state in which it is held by the stopper 15.

When the transfer tool 11 in this state is moved forward together with the trolley 1 to above the relief groove 23 by shortening the actuator 3, the detection rod 26 protruding laterally from the front part of the receiving arm 11b is moved to the cradle 2.
2, the micro switch is actuated, the actuator 3 is stopped, and the motor 9 is activated to lower the transfer tool 11.

Shortly thereafter, the stopper 15 falls forward as described above, but the round bar 25 at the front end is supported by the front wall 22a of the cradle 22 and does not fall.

As shown in FIG. 4, the inclined edge 11 of the receiving arm 11b
When c further descends from the bottom of the cradle 22, the round bar 25 that was placed on the cradle 2
It is transferred onto the bottom wall of No. 2.

When the transfer tool 11 further descends, the detection plate 13 on the lower surface of the receiving arm 11b comes into contact with the lower limit plate 24, so the micro switch is activated to stop the motor 9, extend the actuator 3, and move the dolly. Move 1 back.

When the receiving arm 11b retreats along the skid 21 to the rear of the cradle 22, a micro switch (not shown) is activated and the actuator 3
At the same time as stopping the motor 9, start the motor 9,
The transfer tool 11 is raised.

When the transfer tool 11 rises to near the upper limit, the stopper 15 stands up as described above, receives the round bar 25 on the skid 21, and transfers it to the cradle 22 as described above.

Then, as shown in FIG.
When the round bar material 25 is already stored inside, the detection plate 13 of the descending receiving arm 11b comes into contact with it and stops the descending of the receiving arm 11b directly above the round bar material 25. , the truck 1 starts moving backward.

As a result, as shown in FIG.
The upper round bars 25 successively fall over the stoppers 15 that have fallen forward, and are transferred onto the already stored round bars 25.

As mentioned above, according to the invention, the cradle 2
The drop of the round bar 25 when transferring to the second place is only the height of the tip of the stopper 15 at most, which is small, so the transfer work is carried out quietly and there is no damage to the round bar 25. There is no fear of it getting stuck.

Although the above has described the transfer of a plurality of round bars 25, it is also possible to transfer square bars and other bar-shaped bodies by silently sliding them down on the stoppers.
