Abstract

PURPOSE:To automatically line up a number of object members such as steel pipes each having a circular section without intervention of human power. CONSTITUTION:A vibration skid 3 for applying vibration to a material 1 by means of a vibrator 2 and a turn-down type stopper 4 for pressing the material 1 are provided so that the material 1 can be delivered by several pieces at a time while eliminating mutual entanglement of the material 1. Further, in the rear of them, a transport conveyor 6 and an upper conveyor 12 or a roller are provided for correcting stacking of the material 1 so that several pieces of delivered materials can be lined up one by one. Human power has been conventionally required for eliminating mutual entanglement of materials, however, this work can be thereby automated to eliminate dangerous manual work.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic aligning device for aligning a rod-shaped material such as a steel bar or a target material having a circular cross section such as a steel pipe.

[0002]

2. Description of the Related Art Conventionally, taking steel pipes as an example, when charging various equipment such as a straightening machine, a large number of steel pipes temporarily placed on a placing frame or the like are bundled with ropes and lifted by a crane. It is transported to the skid etc. on the front of the equipment. On the other hand, since the transported steel pipes are to be loaded into the equipment one by one or several ones after removing the rope, it is necessary to collapsing a large number of steel pipes in piles and align them one by one. The steel pipes in the cradle have been aligned to the front by manual work or by forcibly discharging the steel pipes in the cradle with a chain or the like and rolling the skids. Further, as a steel pipe dispensing device, there is an automatic dispensing device described in Japanese Utility Model Publication No. 63-20402. This device is a device capable of automatically dispensing a large number of target materials having a circular cross section of a steel bar pipe one by one at right angles to the rolling direction.

[0003]

In these conventional methods, there is a large amount of bending, and in the case of small-diameter, long-diameter weak target materials, several target materials overlap due to bending and kinking,
It is paid out while being entangled, and since it does not roll on the skid because it bends, human intervention is indispensable, work is troublesome and workability is poor, and not only the efficiency of the equipment is reduced. There was also a safety issue. The present invention solves the above problems of the conventional method,
An object of the present invention is to provide an automatic alignment device capable of automatically aligning a large number of target materials having a circular cross section such as a steel pipe without human intervention.

[0004]

A feature of the present invention is that a vibrating skid by a vibrator and a tipping-type stopper for holding a target material having a circular cross section such as a steel pipe are arranged at regular intervals in the longitudinal direction of the target material. In addition, a conveyor is provided behind the tumbling stopper, and an upper conveyor or a roll that rotates in the circumferential direction is arranged above the conveyor at regular intervals.

[0005]

In the present invention, the entanglement of the target material is eliminated by vibrating the target material by the vibration skid, and the falling stoppers are gradually overturned, and several pieces are discharged to the conveyor and are conveyed. By rotating the upper conveyor or the rolls, it is possible to correct the overlapping of the target materials and to align them one by one.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a side view of an embodiment of the present invention. In addition, the automatic alignment device shown here is configured such that the steel pipe 1 is a target material and is movable. The vibration skid 3 has a spring 18 at one end (right side in FIG. 1) and has a pin structure at the other end, to which the vibrator 2 is attached. In addition, the fall cylinder 4 has a power cylinder 5
Is installed. The falling speed of the falling stopper 4 is variable.

The conveyer conveyor 6 is provided with a chain sprocket (not shown) mounted at regular intervals on a drive shaft 7 which is rotated by a motor (not shown) as a rotating device. Upper steel pipe 1
It is installed in the longitudinal direction. Incidentally, the shaft 7,
8 is provided with rotary drums 9 and 10, and a belt 11 is attached to the rotary drums 9 and 10. Also,
The speed of the conveyor 6 is variable.

The upper conveyor 12 is arranged above the conveyor 6 at a position corresponding to the conveyor 6, and a chain sprocket (a sprocket attached to drive shafts 13 and 14 rotated by a motor (not shown) as a rotating device ( (Not shown) and drive shafts 13, 1
4, rotating drums 15 and 16 are provided, and a belt 17 is attached to the rotating drums 15 and 16.
The speed of the upper conveyor 12 is variable, and the height and
The structure is such that the left and right positions can be changed.

Next, the operation of the apparatus configured as described above will be described. First, the fall stopper 4 is raised by the power cylinder 5. The steel pipes 1 to be loaded into a facility (not shown) are bundled by a rope, lifted by a crane and carried on a vibration skid 3, and then the rope is removed. Further, a large number of steel pipes 1 from which ropes have been removed are piled up on the vibration skid 3 once. In particular, when the bend is large or in the case of a small diameter long material, the steel pipes are entangled with each other. When vibration is applied to the vibration skid 3 by the vibrator 2, the piled steel pipes 1 are vibrated, and the entanglement between the steel pipes 1 is eliminated from the upper part. Next, the overturning stopper 4 is gradually overturned, so that the upper steel pipes 1 in which the entanglement has been eliminated are dispensed onto the transport conveyor 6 one by one. In addition, the fall stopper 4
It is desirable that the speed of (1) is such that the next steel pipe 1 is discharged after the several pipes discharged onto the conveyor 6 are conveyed.

The discharged steel pipes 1 are sent to the conveyor 6, but there is a case where the steel pipes 1 overlap each other. In such a case, since the steel pipes 1 are prevented from moving by the upper conveyor 12 installed above the transport conveyor 6 rotating in the opposite direction to the transport conveyor 6, the steel pipes 1 in the overlapped state are vibrated by the vibration skid 3 The force in the direction of pulling back to the side acts and the overlap is eliminated. The rotation speeds of the upper conveyor 12 and the transfer conveyor 6 and the installation height of the upper conveyor 12 (clearance α in FIG. 2) are preferably determined by the outer diameter and the bent state of the steel pipe. Further, the upper conveyor 12 has the same function even if it is replaced with a roll.

As a result, the overlapping and entanglement of the steel pipes 1 are eliminated, and the steel pipes 1 are conveyed one by one by the conveyer 6 to be finally aligned. Further, although the steel pipe is the target material in the above-mentioned embodiments, the apparatus of the present invention can also be used in the case of the alignment work of the target material having a circular cross section such as a steel bar other than the steel pipe.

[0012]

As described above, in the apparatus of the present invention, the vibration skid for eliminating the entanglement of the target material on the upper part of the bundle by vibration and the fall stopper for gradually discharging the target material are provided. Since the conveyer is provided from the position where the device is provided, and the upper conveyer or roll is provided so as to eliminate the overlap of the several steel pipes 1 delivered above the conveyer, the overlapping / entanglement of the target materials is prevented. They are resolved and sent one by one smoothly. Therefore, the apparatus of the present invention does not require manual labor by the operator, and thus enables automation of the alignment work when inserting into a predetermined equipment, and eliminates the dangerous manual labor such as lifting the target material. it can.
