The present invention relates to a turn table lift, and more particularly, the table is installed to be rotated by a plurality of guide bearings, and in accordance with the X-arm, which is always horizontally maintained in a state of lifting and lowering in proportion to the load. The height of the turntable is always kept constant and relates to a turntable lift that is easy to load and transport the goods packaged / taken out of the same weight through an automated production line.

In general, in the near term, all manufacturing processes establish an automated production line so that the multi-tasking process can be continuously performed as a series of processes in consideration of manufacturing cost and workability / productivity. The packaged goods are discharged by a conveyor, and the workers are stacked in multiple stages on a lift and transported to a storage warehouse or a transport vehicle.

However, due to the nature of automated production lines, tens of thousands of items are produced per day, and as workers have to lean their backs and stack and transport them from the bottom of the lift into multiple stages, the work efficiency is greatly degraded. In the case of heavy physical labor caused by the complaints of occupational diseases such as herniated discs, fractures.

Accordingly, the present applicant in the Republic of Korea Patent Application No. 2004-96785 (name: table lift) is proportional to the lifting stroke of the table corresponding to the load, as well as the transfer distance and speed control per weight according to the intermediate stop function As a result, the patent was filed for a table lift that improves work efficiency by simplifying the loading and transport of goods packed / drawn with the same weight through an automated production line.

For example, in the above-described table lift, the table lifts up and down a fixed rail and an auxiliary rail having a predetermined inclination angle through a bearing train, and the bearing train has a restoring force as the spacing is separated by a tension spring. The work height is always kept constant because the position of the table is changed in proportion to the load. As such, the fixed rail and the auxiliary rail for guiding the table to move up and down must be installed at both ends of the table in the transverse direction as long as the stroke distance, so that the loading / unloading work of the goods is performed only in the front direction of the table. Therefore, the use is limited to the proposed use of stacking / carrying small quantities of goods discharged on the conveyor of automated production lines.

In addition, in stacking a large amount of goods in a container or a warehouse, the goods are mainly stacked on a pallet in a double row and transported using a transport means such as a forklift truck.
