DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for dispensing a reinforcing bar, that is, a rod-shaped body, used for an automatic welding machine in a reinforcing bar manufacturing process in a manufacturing plant of an autoclave-cured lightweight cellular concrete product (ALC) as a concrete product. It is about.

[0002]

2. Description of the Related Art The transverse streak used for reinforcing wire mesh of ALC products has a streak diameter of 3 to 7 mm and a length of 1500 mm or less, so that the conventional transfer technique is a belt type.

[0003]

As described above, the horizontal streak, that is, the rod-shaped body is transported by a belt transport system. During the transport, the rod-shaped body is guided by a side guide of a payout gate so as not to come off the belt conveyor. The bar is always conveyed to a specific position on the belt conveyor. Then, in order to positionally supply the rod-shaped body to the next process, the rod-shaped body is positioned against a stopper on a belt. While the bar is stopped by the stopper for positioning, friction occurs between the bar and the specific position of the belt conveyor. As a result, the belt conveyor is severely worn.
As a result, a sticking trouble occurs when the rod-shaped body is dispensed and supplied to the next process, and stable supply cannot be performed. In addition, the life of the belt is short and the frequency of belt replacement is high. Further, since the rod-shaped body repeatedly rebounds when stopped by the stopper, the positional accuracy at the time of dispensing is not obtained. Therefore, an object of the present invention is to provide a rod-shaped dispensing device that can stably convey a rod-shaped object.

[0004]

SUMMARY OF THE INVENTION The present invention provides the following rod-shaped dispensing apparatus for achieving the above objects. That is, in a dispensing device that transports a rod to a dispensing position in the longitudinal direction and dispenses the rod in a direction orthogonal to the transport direction, a flat roller that is disposed in the dispensing position longitudinal direction and transports the rod in the longitudinal direction. And a stopper for stopping the bar-shaped body conveyed by the conveyor at the dispensing position, and a pair of sides arranged on the conveyor and extending on both sides for guiding the conveyed bar-shaped body. A rod-shaped dispensing device comprising: an elongated dispensing gate having a guide; and driving means for moving the dispensing gate from above the conveyor in a direction orthogonal to a conveying direction.

[0005]

The bar-shaped body guided by the guide of the payout gate and conveyed on the roller with the built-in magnet is positioned by the stopper, and simultaneously with the positioning, the bar-shaped body is conveyed to the next step by the payout gate.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. A description will be given of a rebar payout apparatus used in an automatic welding machine in a reinforcing wire mesh manufacturing process in an ALC manufacturing factory shown in FIGS. 1 to 3, but it can also be used for general rod-shaped body transport and payout. Reference numeral 1 in FIG. 1 denotes a plurality of flat magnet rollers, which are arranged below the payout gate 2 in the longitudinal direction of the gate, and a plurality of flanged magnet rollers 3 are arranged on a front extension of the flat magnet roller 1. ing. These rollers 1 and 3 are driven by a drive motor 4
Is driven via a drive pulley 7 by a belt 6 driven by the drive transmission of the belt 5. A belt pressing roller 8 is provided between the pulleys 7 to apply tension to the belt, and the rollers 1 and 3 as described above constitute a roller conveyor for transporting the rod-shaped body as a whole. Below the elongated payout gate 2, there are a pair of side guides 2a, 2b arranged along the roller conveyor and extending on both sides of the bar to be conveyed, and guided by the flange of the flanged magnet roller 3. The rod is guided and conveyed by the side guides 2a and 2b of the payout gate 2. The payout gate 2 is reciprocated by a payout air cylinder 9 via a piston rod 10 in a payout direction orthogonal to the transport direction of the rod. When reciprocating, the bracket 1
The payout guide bar 13 is guided along one payout guide 12. A bar-shaped stopper 14 is provided on the roller 1 disposed at the end of the flat type magnet roller 1, and a detection sensor 15 which is turned ON at a position where the bar hits the stopper 14 is provided.

The above apparatus is a dispensing apparatus which transports a rod to a dispensing position in a longitudinal direction and dispenses the rod in a direction perpendicular to the transport direction. The magnet roller has a flat type roller 1 which transports the rod in a longitudinal direction. There is a stopper 14 for stopping the rod-shaped body conveyed by the magnet roller conveyor at the dispensing position. Also. The payout gate 2 has a pair of side guides 2a and 2b which are arranged along the conveyor and extend on both sides of the bar to be conveyed. The dispensing gate 2 has a driving unit including a dispensing air cylinder 9 for moving the dispensing gate 2 in a horizontal direction, that is, a direction orthogonal to the transport direction, from above the conveyor.

Therefore, when the rod-shaped body pulled out from the take-up reel and cut into a certain size comes on the roller conveyor, it is first guided and transported by the flange of the flanged magnet roller 3, and is composed of the next flat type magnet roller 1. It is transported to a roller conveyor, where it is guided and guided by side guides 2 a and 2 b of the payout gate 2 and hits a stopper 14. At this abutted position, the detection sensor 15
Detects the rod-shaped body, and the payout gate 2 moves in the paying-out direction by the payout air cylinder 9 by this detection, and pays out the rod-shaped body to the welding process. At the time of dispensing, since the roller 1 is a flat type, the rod-shaped body does not catch on the roller, and the dispensing is performed smoothly. According to the above, the flat type magnet roller 1 facing the payout gate is a wear-resistant magnet roller, so that the conveyor does not wear while the rod-shaped body is stopped by the stopper 14,
The rebound does not repeat when stopped by the stopper 14 due to the holding action of the magnet bar.

[0009]

As described above, according to the present invention, while the bar is stopped by the stopper, the roller is not worn by the wear-resistant magnet roller, and the rod is held by the stopper by the holding action of the magnet. There is no repulsion of the body and the positional accuracy at the time of dispensing is improved. In addition, the rod-shaped body only makes line contact with a plurality of rigid rollers in the dispensing direction, so it can be smoothly dispensed against the holding force of the magnet, and since the roller is flat, there is no object that the rod-shaped body gets caught and the belt when dispensing There are no accidents like a conveyor. In addition, the attraction force of the magnet acts evenly, and parallel payout is possible even with a short payout gate.
