Description

Engine power system of goods transfer stacker machine

The present invention is a new high-efficiency installed in the logistics stacker machine (Stacker M / C, Robot) that performs the loading and unloading of the product among the components constituting the automated logistics system (Stocker System) in the production plant, such as semiconductor, LCD, PDP It relates to a power train.

In general, in the production plant of semiconductor, LCD, PDP, etc., an effective loading & unloading of each process logistics and an automated logistics system (Stocker System) are established to systematically transport and manage logistics.

This logistics automatic system is equipped with a shelf-type stocker for mass loading and storage, and a stacker machine (Stacker M / C, Robot) for logistics transportation that performs the integrated management of each cell ID information in the product and the shelf as well as the entry and exit of products. do.

However, the conventional power transmission device installed in the stacker machine (Stacker M / C, Robot) for transporting logistics,

The structure was unnecessarily complicated, and the manufacturing cost was high, but the operation efficiency was low, and there was a problem that the cost burden was high due to frequent repairs.

In particular, there was a serious problem that malignant tremors, vibrations, and shakes occurred in the safe transportation of products during loading and unloading operations for logistics transportation.

That is, in the conventional power transmission structure, sprockets are installed on one shaft (one driving shaft) and the other shaft (the driving shaft on the other side), respectively.

It consists of a method or device that transmits power by walking a chain that has a large number of links connected to each other between the sprockets on both sides.

This structure is difficult to smoothly and precisely drive and rotate transfer due to the deflection of the chain during use due to the characteristics of the rotational drive between the chain and the sprocket.

Although separate tensioning devices can be installed on both sides of the chain to prevent sagging to some extent, there are significant problems associated with significant cost losses.

In addition, the conventional chain-type power connection system because of the characteristics of the chain, as the use time elapses, the sagging or sagging phenomenon continues to deepen,

There is also a disadvantage, which is quite inconvenient because it must be continuously adjusted and managed after checking the tension degree of the tension control device in real time.

Furthermore, in the conventional chain drive method, even if the degree of the tension device described above and the relative management of the adjustment is perfect,

Since the chain is inevitably generated at every pitch when the interlocking action of the plurality of links and sprockets constituting the chain is inevitable,

In the rotation operation of the driven shaft rotated by the rotational power transmitted from the driving shaft, a predetermined shake, vibration, and tremor occur.

High precision rotational transfer was not possible, so there was a problem that high-efficiency logistics transfer and highly accurate loading and unloading of the more sensitive ultra-precision high-tech products were virtually impossible.

Accordingly, the present invention has been devised to eliminate the above problems, and greatly improved arm drive power transmission means, which is the substance of loading and unloading transportation for logistics, enables simple and precise smooth transportation operation, in particular, logistics transportation. It is a technical task completed with the focus on providing an excellent high performance logistics transfer stacker machine that guarantees high efficiency and stable operation without heavy noise, vibration, vibration, or shaking.

The present invention for achieving the above technical problem is the support frame 10 is provided with two drive motor (M), the driving shaft (M); A first arm (110) extending one step at a predetermined length from the support frame; A second arm 120 extending longer at the other end of the first arm 110; A driven shaft 12 includes a driven shaft 12 at one end of the first arm 110 to which the second arm 120 is coupled, and a rotary connecting shaft 13 therebetween. A gear reducer (200) configured between the motive shaft (11) and a drive motor (M); A prime bevel gear 130 is installed between the prime shaft 11 and one end of the rotary connecting shaft 13; The driven bevel gear 140 is installed between the other end of the rotary connection shaft 13 and the driven shaft 12.

As described above, the power transmission device of the logistics transport stacker machine of the present invention as described above, the power transmission system is made of a bevel gear system with no or minimal defects such as play or backlash and vibration, vibration, sagging. This ensures more precise and stable movement during the loading / unloading operation of the tacker, and enables long-term use without the need for separate tensioning means, especially for high-precision and sensitive cutting-edge products. It can be effectively used as well, the expectation is indeed a great invention.
