Abstract

PROBLEM TO BE SOLVED: To keep constant the traveling speed in the conveyer cross direction of works for uniform intervals by supporting a guide roller so as to rotate in a horizontal plane at a small distance from a conveyance surface, and bringing the works into contact with the outer periphery of the guide roller at a fixed position so as to be rotated. SOLUTION: Works (a) on the conveyance surface of a conveyer belt 1 are guided to a fixed guide plate 5 and a movable guide plate 9, aligned in a row, and are brought into contact with the fixed position of the outer periphery of a guide roller 19. The guide roller 19 is rotated in an arrow direction, and the work (a) moves in the cross direction of a conveyer 1 along its outer periphery and is released. As a result, fixed interval is generated between the works (a), and the works are aligned and conveyed. The time of the guide roller's restraining the work (a) is also made uniform.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for separating workpieces such as sintered parts which are successively conveyed by a belt conveyor so as to be separated at a constant interval and for carrying them in line on the belt conveyor. .

[0002]

2. Description of the Related Art For example, when a powder molded product molded by a press molding machine is conveyed by a conveyor and charged into a sintering furnace, if the powder molded products are in contact with each other in the furnace, they will stick to each other and burn. Since the powder may be bound, it is necessary to load the powder molded product into the furnace at regular intervals. To this end, Japanese Patent Laid-Open No. 5-132125 discloses a device for aligning intervals between powder molded products. The interval aligning device is provided with a guide plate on the upper surface of the conveyor so that the inclination angle can be adjusted in the horizontal direction orthogonal to the traveling direction, and the moving speed is slowed by frictional resistance of the powder molded product on the conveyor while hitting the guide plate. In this way, the space can be opened.

[0003]

However, in the above-mentioned conventional spacing aligning apparatus, the force applied in the width direction of the conveyor exerted on the powder molded product by the dynamic frictional force with the inclined surface of the guide plate is not always constant, so that the powder molding is not necessarily performed. There is a problem that the moving speed of the product in the width direction of the conveyor is not constant and the intervals are likely to be uneven.

[0004]

SUMMARY OF THE INVENTION A work space aligning and conveying apparatus according to the present invention is intended to solve the above problems.
The guide roller is supported so as to be rotatable in a horizontal plane at a slight distance from the conveying surface on the belt conveyor, and the work conveyed by the belt conveyor is brought into contact with the outer peripheral surface of the guide roller at a fixed position. The guide roller is thereby rotated in a fixed direction.

[0005]

The work contacting the outer peripheral surface of the guide roller is moved and opened in the width direction of the conveyor when the guide roller is rotated by the contact with the work. For this reason, since the guide roller is rotatably supported, the time during which the guide roller restrains the work becomes uniform and the intervals become uniform.

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of the interval aligning and conveying apparatus for the works, and FIG. 2 is a left side view thereof. In the figure, 1 is a motor 2
The first belt conveyor 3 in which the conveying belt moves at a constant speed in the horizontal direction of the arrow by the operation of the above, is a second belt conveyor provided so as to be continuous with the belt conveyor 1, and the belt conveyor 3 is a motor 4 The operation of causes the transportation belt to move at the same speed. Reference numeral 5 denotes a fixed guide plate fixed to one side edge of the belt conveyors 1 and 3 via mounting pieces 6 and 6. Reference numeral 7 denotes a mounting base provided on the other side edge of the belt conveyor 1. The mounting base 10 of the movable guide plate 9 is loosely fitted on the upper surface of the mounting base 7 so as to be slidable along the groove 8, and the lever 17 is provided. The movable guide plate 9 can be moved in the width direction of the conveyor to adjust the set position by operating the. The fixed guide plate 5 and the movable guide plate 9 are opposed to each other on the belt conveyor 1 and the belt conveyor 3, and the position of the movable guide plate 9 is adjusted so that the works a can be arranged in a line in the space between the plates. It The end portions 5 ', 9'of the fixed guide plate 5 and the movable guide plate 9 on the belt conveyor 1 side are inclined outward in a bent shape, and the work a conveyed by the belt conveyor 1 is conveyed.
Guide them between the plates and arrange them in a line.

Reference numerals 11 and 12 denote optical sensors provided at regular intervals so as to detect the work a arranged between the guide plates 5 and 9. As shown in FIG. When lined up, the signal from the sensor 11 turns on the motor 4 to operate the belt conveyor 3. Further, when the number of the works a is reduced and the number of works a to the other sensor 12 is decreased, the power of the motor 4 is turned off by the signal of the sensor 12 to stop the belt conveyor 3. The belt conveyor 1 is constantly operated regardless of the number of such works a arranged.

Reference numeral 13 denotes a mounting base provided around one side edge of the belt conveyor 3. A groove 14 is formed on the upper surface of the mounting base 13, and a base of an arm 15 is slidable along the groove 14. A lever 1 in which 16 is loosely fitted and pivotally supported by the base portion 16.
By operating 7 to loosen the fitting, the arm 15 is moved in the conveyor width direction so that the setting position can be adjusted. A support shaft 18 is vertically supported on the tip of the arm 15, and a plastic guide roller 19 is rotatably supported by interposing a bearing on the lower end of the support shaft 18. As a result, the guide roller 19 is supported at a slight distance from the conveying surface on the belt conveyor 3 as shown in FIG.

In the work interval aligning / conveying device thus constructed, the works a on the conveying surface of the conveyor belt 1 are guided by the fixed guide plate 5 and the movable guide plate 9 to form a line and the outer circumference of the guide roller 19. Abut the fixed position of the surface. Then, the work a is moved along the outer peripheral surface of the guide roller 19 in the conveyor width direction and is released while rotating the guide roller 19 in the direction of the arrow shown in the figure. For this reason, a fixed interval is formed between the works a and they are aligned and conveyed. The distance between the fixed guide plate 5 and the movable guide plate 9 is appropriately set by refastening the lever 17 and moving the movable guide plate 9 according to the size of the work a. Further, the position and outer diameter of the guide roller 19 are also appropriately set according to the size of the work a and the required formation interval between the works a.

[0010]

As described above, according to the spacing alignment transport apparatus of the present invention, the works are moved and aligned in the width direction of the conveyor by the sub-rotation of the guide rollers, and a space is provided between the works. Since the rollers are rotatably supported, there is an effect that the time during which the guide rollers constrain the work can be made uniform and the intervals can be made uniform. Further, since the work is not unnecessarily applied with a large frictional force, it is possible to prevent the work from being deformed.
