Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a round bar supply apparatus for subdividing a large number of round bars, such as metal, glass fiber, synthetic resin, and ceramic, and supplying them to other devices.

[0002]

2. Description of the Related Art In general, a feeding apparatus of this type separates a small number of round bars from a stacking section where a large number of round bars are stacked and transfers the separated round bars to a next aligning section. 1 wood
The apparatus is configured to be separated from each other and supplied to another part or apparatus. Then, in order to separate several round bars from the stacking section, a member called a kicker is moved up and down, and at the time of upward movement, the round bars in the stacking section are scooped up and separated from other round bars. It is sent to the next alignment part at the dead point,
They are rolled and moved along the slope, and are further aligned at the alignment section before being supplied to other parts or devices.

[0003]

However, the round bars on the collecting section are not always aligned in parallel with each other. As shown in the round bar a1 in FIG. 7 (a), the bar may be oblique and overlap with another bar in an intersecting state, and as shown in the round bar a2 in FIG. 3
The mm round bar may flex and partly intersect with other round bars. In such a case, the kicker may pick up the round bar material in a crossed state and send it to the alignment section as it is. Since the elongated round bar is easy to bend and hard to roll, it is difficult to return to the parallel state once it is in the crossed state. The only way to do this is to stop the device and return it manually. Therefore, conventionally, in order to prevent such inconvenience, the operator must frequently check the feeding state, which is troublesome.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and to provide a round bar feeder capable of reliably feeding a round bar on an accumulation section to the next alignment section without intersecting. I do.

An alignment for aligning a small number of round bars a sent separately from the stacking section 2 is provided on the base 1. A unit 3 is provided, and a supply unit 4 for sending out the round bar materials a sent from the alignment unit 3 one by one is provided at the front of the base 1.

The stacking unit 2 has a support member 5 projecting rearward from an upper portion of the base 1 with an adjustment bolt 6 mounted upward and a front end rotatably mounted on the base 1 having a substantially L-shaped cross section. 7 is arranged so as to be supported on the adjusting bolt 6. The loading member 7 is disposed so as to be inclined downward toward the front, and the inclination is adjusted by the adjustment bolt 6.

The aligning section 3 inclines the guide plates 8 arranged at intervals on the base 1 one by one at the front and the rear at a low angle toward the front, respectively. The rotors 9 and 10 are arranged in parallel, and a bar guide 11 that supports several round bars a and guides it to the alignment unit 3 is located on the stacking unit 2 side at a position higher than the bottom of the stacking unit 2. It is provided in. The rear end of the bar guide 11 has an inclined portion 11a.
A vertical hanging portion 12 is formed through the opening. The bar guide 11 and the guide plate 8 are formed lower on the output side (output side) than on the input side (feed side). At the front end of the guide plate 8, a stop piece 13 for stopping the rolling of the round bar material a is formed so as to rise. The inclined portion 11a is not always necessary. The hanging portion 12 and the bar guide 11 may be formed so as to extend and directly contact with each other.

Each of the feed rotors 9 and 10 is a drive motor 1
4, 15 are connected. Each feed rotor 9, 1
0 has engagement grooves 16 and 17 formed on its peripheral surface in the longitudinal direction. The rear feed rotor 9 is formed so that about two to four round bars a are engaged with one engagement groove 16, and the front feed rotor 10 is formed with one to two engagement grooves 17.
The round bar members a are formed so as to engage with each other.

The supply section 4 includes a kicker 18 arranged at the front end of the guide plate 8 and a guide section 19 extending forward from the upper end of the stop piece 13. The kicker 18 is connected to an air cylinder device 20 and a guide 19
Is inclined low toward the front. The upper end of the kicker 18 is formed obliquely, and the rear vertical surface of the kicker 18 is disposed at a position retracted from the rear vertical surface of the stop piece 13 by substantially the diameter of the round bar a. In addition, another device is usually arranged in front of the guide portion 19, but is omitted here.

Next, a rake means 21 is arranged between the stacking unit 2 and the alignment unit 3. This scooping means 21
Is a plate-like kicker portion 22 having a wedge-shaped upper end.
And an arm-shaped rake portion 2 that is inclined low toward the front.
3 are provided. The rake 23 is provided with the guide plate 8
It is arranged at a shifted position so as not to interfere with the camera. A stopper 24 is formed at the front end of the rake 23. The stopper 24 is preferably provided so as to be movable in the front-rear direction. The amount of the round bar a supported on the rake portion 23 can be adjusted by the position of the stopper 24. The rake section 23 and the kicker section 22 of the rake means 21 may be formed integrally. Since the kicker portion 22 is formed in a plate shape, even if a part of the round bar material is deformed or overlapped, it does not hit the surface of the kicker portion 22 and protrude toward the alignment portion 3 side. .

The kicker 2 of the scooping means 21
The lower end of 2 is connected to an air cylinder device 25 fixed to the base 1. Thus, the rake means 21 is configured to move up and down between the stacking unit 2 and the bar guide 11, and is configured to operate to swing slightly up and down at or near the top dead center. The driving device for operating the rake means 21 is not limited to the air cylinder device 25. Other mechanisms may be used.

Next, a description will be given of an operation mode of the round bar material supply device having the above-described configuration.
Is adjusted to an appropriate gradient, and a large number of round bars a are placed on the stacking unit 2. Next, when the rake unit 21, the air cylinder devices 25 and 20 of the supply unit 4, and the drive motors 14 and 15 of the feed rotor are operated, the rake unit 21 moves upward as shown in FIG. Scoop up several round bar materials a on top. Round bar a picked up
The bar guide 11 is initially supported by the kicker portion 22 and
Of the rake portion 23 at a position beyond the bar guide 11 and stops by hitting a stopper 24 at the front end thereof.

When the rake means 21 reaches the top dead center or its vicinity, the rake means 21 swings up and down by a small stroke by the air cylinder device 25 as shown in FIG. As a result, the round bar a bounces on the rake portion 23 and is shaken up and down, so that it moves along the slope and is parallel to the length of the device (parallel to the other round bar a). Becomes Therefore, even if there is an unstable round bar a obliquely crossing the other round bar a on the rake portion 23, it is corrected to a stable state at the time of bouncing.

Next, when the rake means 21 moves down from the top dead center after swinging, several round bars a at the front end of the rake portion 23 are received by the bar guide 11 of the alignment portion 3 and follow the inclination thereof. To move to the rear rotor side.

Since the rear feed rotor 9 is rotating in the aligning section 3, as shown in FIG. 2, two or three round bars a on the front end side of the round bar material a supplied to the bar guide 11 by the rake means 21. Engages with the engaging groove 16 of the feed rotor 9 and is separated from the other round bar material a, and then rolls on the next guide plate 8 to be aligned in front of the front feed rotor 10. Since the front feed rotor 10 is also rotating, the front end side of the round bar material a
２2 are engaged with the engagement groove 17 of the feed rotor and separated from the other round bar material a, and then roll on the next guide plate 8 and stop and align before the stop piece 13.

As described above, the round bar material a supplied onto the guide plate 8 by the rake means 21 is transported by being separated little by little by the two front and rear feed rotors 10 and 9. Does not overlap during the feeding. The reason why a large number of round bars are not supplied at a time before the rotors 9 and 10 are fed at once is because the thin round bars are easy to bend and are difficult to roll.
This is because, when a large number of bar materials are supplied, the previous bar materials may interfere with the bar material and stop on the line.

Finally, the kicker 18 is actuated by the supply unit 4, one round bar a is engaged with the upper end of the kicker 18 and lifted, and is further supplied to the guide unit 19 at its top dead center. Further, the above operation is repeated, and the round bar material a of the guide portion 19 is supplied to another device one by one.

As shown in FIG. 6, a swinging device for swinging the stacked round bars up and down may also be provided at the bottom of the stacking member 7 of the stacking unit 2. This rocking device,
A push-up portion 28 is attached to an air cylinder device 27 fixed to a support 26 on the lower surface of the loading member 7, and the push-up portion 28 is provided so as to be able to protrude and retract inside the loading member 7 from an opening formed at the bottom of the loading member 7. In this case, a plurality of members may be arranged at intervals along the length of the loading member 7.

When the swinging device provided on the loading member 7 is operated, the push-up portion 28 moves up and down through the opening of the loading member 7 to swing the round bar. As a result, the round bar bounces on the loading member 7, moves forward along the inclination thereof, and stabilizes in a state parallel to the longitudinal direction of the apparatus. Therefore, even if there is a round bar material obliquely crossing another round bar material on the stacking member 7, the posture thereof is correctly corrected at the time of bouncing. The swinging device is operated in a state where the rake means 21 is located above the bottom dead center, the kicker portion 22 serves as a wall, and the rocked round bar a does not move to the rake means 21 side. Is preferred.

As described above, the rake unit 21 having the rake unit 23 with the stopper 24 is disposed between the stacking unit 2 and the alignment unit 3, and the rake unit 21 is moved up and down and the top dead center or Since it is connected to the air cylinder device 25 that swings up and down slightly in the vicinity thereof,
When the rake unit 21 is swung up and down by a small stroke by the air cylinder device 25 at a position at or near the top dead center, the round bar material b bounces on the rake portion 23 and shakes up and down. So that it moves along the slope and is in a stable state parallel to the length of the device. Therefore, even if there is an unstable round bar a obliquely crossing over the other round bar a on the rake portion 23, the round bar on the stacking portion 2 is corrected to a stable state when bound. Material a
Can be sent to the next aligning section 3 without fail.
