Abstract

PURPOSE:To transfer a work pushed out by a processing device passively or actively at the predetermined speed by suspending a power transmitting means across a driven wheel provided on a roller and a driving wheel fitted to a clutch. CONSTITUTION:A drive shaft 21 is connected to the shaft 20 of a speed reducer 19, the drive shaft 21 has a cam clutch 22, and the first sprocket 23 serving as a driving wheel is fitted to this cam clutch 23. A chain 24 on the primary side serving as a power transmitting means is suspended across the first sprocket 23 and a sprocket 17. When the cam clutch 22 is disengaged, a conveyor roller 12 is freely rotated, thus it is passively rotated by a steel frame S pushed out by a steel frame assembling device 3. On the other hand, when the cam clutch 22 is engaged, the rotation of the drive shaft 21 is transmitted to each conveyor roller 12 via the chain 24, each conveyor roller 12 is actively rotated, thus the steel frame S on the conveyor roller 12 is actively transferred.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a conveying device. More specifically, the present invention relates to a steel frame conveying device.

[Prior art]

Conventionally, when a steel frame with a special shape such as an H-shape or an I-shape in cross section is formed by assembling and tacking with a steel frame assembly machine while moving the workpiece, the steel frame formed with the steel frame assembly machine is , are successively pushed out to the downstream conveyance device.

However, in the conventional conveying device, since the conveying rollers are free rollers, it is not possible to actively convey the assembled steel frame once the steel frame leaves the steel frame assembly device.

[Purpose of the invention]

The present invention solves such conventional drawbacks, and the conveying roller passively rotates according to the steel extruded from the steel frame assembly device until it leaves the steel frame assembly device, and The purpose of the steel frame is to provide a device that can be actively conveyed at a predetermined speed.

[Structure of the invention]

That is, the conveying device of the present invention includes a large number of rotatable rollers, a clutch provided on the drive shaft, and a power transmission means between the driven wheel provided on each roller and the driving wheel attached to the clutch. It is characterized by being crossed.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 8 is a plan view showing a steel frame assembly line, and this steel frame assembly line 1 is composed of a feeding device 2, a steel frame assembly device 3, and a conveying device 4.

This conveying device 4 has a large number of conveyor rollers 12 rotatably disposed on an upper frame 11. That is, as shown in FIG. 1, each conveyor roller 12 is rotatably attached to the upper frame 11 via a pair of right and left diamond flange units 13.1 and 3a. In the figure, the unit 13 on the right side is supported by a push bolt 15 attached to a frame 14 protruding inward from the upper frame 11, and the unit 13a on the left side is supported by a push bolt 15 attached to the upper frame 11. The level of each conveyor roller 12 can be adjusted by each push bolt 15. Further, by supporting each conveyor roller 12 from below with each push bolt 15, it is possible to prevent each conveyor roller 12 from escaping downward. Further, as described above, the use of the diamond flange type unit 13.13a has the advantage of reducing machining and reducing manufacturing costs. One foot 1 of each of the above conveyor rollers 12
A sprocket 17 as a driven wheel is attached to 6a.

On the other hand, a drive shaft 21 is connected to a shaft 20 of a reduction gear 19 via a chain coupling 18 . This drive shaft 21
has a cam clutch 22, and this cam clutch 2
A first sprocket 23 as a driving wheel is attached to the first sprocket 23 and a primary chain 24 as a power transmission means between the first sprocket 23 and the sprocket 17.
is being passed over.

When the cam clutch 22 is in the "disengaged" state, the conveyor roller 12 rotates freely and is therefore passively rotated by the steel frame S pushed out from the steel frame assembly device 3. On the other hand, when the cam clutch 22 is "on", the rotation of the drive shaft 21 is transmitted to each conveyor roller 12 via the chain 24, and each conveyor roller 12 actively rotates, so that the steel frame on the conveyor roller 12 S is actively transported.

Furthermore, the drive shaft 21 has a second sprocket 25 between the chain coupling 18 and the cam clutch 22. A secondary chain 27 is stretched between the second sprocket 25 and the third sprocket 26, and power is transmitted from the downstream conveying device 4A to the upstream conveying device 4B. In FIG. 7, 28 is the fourth sprocket,
This fourth sprocket 28 is attached to the cam clutch 22. Additionally, one sprocket (not shown) in the fourth cam clutch 28 and the upstream conveying device 4B is connected to the fourth cam clutch 28.
When the next chain (not shown) is stretched and both cam clutches 22 are "on", the downstream and upstream conveyor rollers 12 rotate synchronously.

In the figure, reference numeral 30 indicates a drive motor, 73 indicates an idle roller in the steel frame assembly device 3, and 84.842 indicates a pinch roller.

In the above description, a conveyance device that is attached to a steel frame assembly apparatus has been described, but the present invention is not limited to this, and it goes without saying that the present invention can be widely used as a conveyance device.

〔Effect of the invention〕

As described above, the present invention provides a large number of rotatable rollers, a clutch is provided on the drive shaft, and a power transmission means is provided between the driven wheel provided on each roller and the driving wheel attached to the clutch. Since the workpiece is spanned, the workpiece such as a steel frame will passively rotate according to the workpiece pushed out from the processing equipment until it leaves the processing equipment such as the steel frame assembly equipment, and the workpiece that has left the processing equipment will rotate at a predetermined speed. This allows for active transportation.
