It relates to a punching device of a large-sized Thomson machine, which simply implements a power transmission structure necessary for lifting and lowering.

In general, a device called "Thompson machine" that can simultaneously perform lamination, punching, and gripping work on industrial tapes and sheets used in the electronic field, has a wooden blade with a blade fitted in accordance with the shape of the product to be processed. Or it has a punching part (or punching machine) which can process a product into a desired shape, pressing up and down.

Such thomson machine is usually provided with a fabric supply unit for supplying a wound fabric (or sheet), and a die (wood mold) provided with a jig part and a cutting blade on which a fabric for die cutting the fabric supplied from the fabric supply unit is placed. Discharge upper and lower plate portion for the upper and lower movable upper and lower plate portion to process the fabric, and the discharging fabric to pull the fabric processed in the punching portion at a constant pitch through the extrusion roller and the auxiliary roller driven by a motor By providing each part, it is used extensively for the fabrication of the precise product which an optical component, an electronic component, etc. require.

The Thomson machine is very diverse in kind, and may be divided into small, medium, and large sizes depending on the size of the product to be processed.

Among the Thomson machines classified by size, the large Thomson machine is specialized in processing 65-inch large TV / screen prism sheet, diffusion sheet, reflective sheet and various large fabrics used in various industries.

On the other hand, the punching unit that can process the product into the desired shape while pressing the wood die (or wood mold) with the blade inserted up and down to fit the shape of the product to be processed in the Thomson machine as described above employs a conventional punching machine It is common to use it.

Prior art related to such a conventional punching machine is published in Republic of Korea Utility Model Publication No. 0304095 (2003.14. 2003), Patent No. 1194816 (August 25, 2012.), Publication No. 2014-15781 (2014.2) .7, published), and Japanese Patent No. 1520866 (August 1, 2015).

For example, the punching portion disclosed in the Patent Publication No. 1520866, the upper plate which can perform the punching operation by pressing by lifting up and down the wood mold containing the blade on the upper surface of the main housing of the workbench regularly It is disclosed that a lifting upper plate portion including a plate, a jig portion in the form of a plate disposed to face the lifting upper plate portion, and an upper plate driving portion that provides a driving force for raising and lowering the lifting upper plate portion.

Here, the elevating top plate is a portion that is mounted so that the wood mold can be pulled out and charged, the upper plate of the elevating top plate is assembled to be fixed to the four corners of the elevating shaft through each of the elevating shaft to perform the punching operation while elevating by the elevating shaft It is assembled to help.

Then, the wood mold is fixed to the upper plate of the upper side of the punching portion to grip the handle, can be pulled out from the elevating top plate portion, and the blade is embedded in the buffer material or the like in accordance with the shape to be processed.

In addition, the top plate is regularly pressed to the fabric passing through the upper surface of the jig in the state in which the mold is loaded and performs the stamping or cutting operation (semi-cut work or complete knife work) to the shape to be processed on the fabric.

In particular, the upper plate driving portion is a driving portion for raising and lowering the elevating shaft by the crank shaft rotation, the upper plate driving portion has a configuration including a main motor, a crank shaft including a connecting rod and a cam shaft.

Therefore, when the crankshaft and the camshaft are driven by the driving of the main motor, and the crankshaft rotates one turn (that is, one stroke), the lifting shaft connected to be linked by the connecting rod of the crankshaft is lifted and lowered once, thereby making one punching operation. It has a configuration in which the connecting rod and the lifting shaft of the crankshaft are interlocked with each other so as to perform the operation.

As such, the crankshaft and the camshaft repeatedly perform the shaft rotation according to the driving of the main motor, and each time the crankshaft and the camshaft makes one rotation (that is, one stroke), the elevating top plate moves up and down once. The punching operation is made, and the punching operation is performed continuously and repeatedly in accordance with the fabric that is transferred from the fabric supply unit to the punching position of the punching unit, and the driving of the main motor is automatically controlled through the control signal of the controller.

By the way, in the case of the method of driving the elevating shaft in the punching portion as the crankshaft rotation as described above, it can be said to be suitable when the size of the punching portion is small and medium, but in the punching portion that is applied to a large Thomson machine, the specification of the elevating plate portion is very large ( For example, the width x length is about 150 cm x 150 cm), in order to interlock the four lifting shafts by the crankshaft and the connecting rod method, the specification of the crankshaft and the connecting rod as well as the large-capacity drive motor must be increased. There was a downside.

In particular, since it is difficult to simultaneously drive the four lifting shafts by the crankshaft and connecting rod or the known rotary method, the four lifting shafts are individually lifted and lowered by the driving motor or the hydraulic cylinder method. In many cases, it is not desirable in terms of space utilization, weight reduction of the product and the simplification of product specifications, and economic aspects of the product, and the design of the organic layout and combination of each component becomes very complicated or the installation area is increased. There was a drawback that the design specification of the product is large due to the large occupancy.
