This is because the lifting cylinder 220 is operated, The rotary plate 500 is lifted with the elevation of the elevation member 300 and the heating plate 30 is opened from the workbench 20. [

At this time, in the process of opening the heating plate 30, the fabric 60 is attracted to the work table 20, and is prevented from rising along the heating plate 30. [

10 is a view illustrating a process of replacing a hot plate and a cooling plate in a hot press having a lifting operation and a rotation changing structure of the heating plate and the cooling plate according to the present invention, As a heating plate replacement state and a cooling plate replacement state of a hot press,

This is enabled by the operation of the pivoting cylinder 620 as shown in Fig. 10, in which the pivoting cylinder 620 is operated to draw the cylinder rod 621 downward, and at this time, the end of the cylinder rod 621 One end of the connected rotation unit 630 rotates downward while drawing a call with the rotation axis 400 of the other end as an axis.

That is, as described above, the rotation table 630 rotates the rotation axis 400 fixed to the other end when one end rotates downward, and the rotation plate 500 fixed to the rotation axis 400 rotates 90 degrees to the left And the cooling plate 40 positioned on the right side is positioned at the position of the heating plate 30 and is opposed to the work table 20.

12 is a cooling state view of a hot press having a lifting operation and a rotation changing structure of the heating plate and the cooling plate of the present invention,

The cooling operation is performed as shown in FIG. 12, in which the lifting cylinder 220 is operated to pull the cylinder rod 222 downward and lower the lifting member 300 like the thermal pressing operation by the heating plate 30 The rotary plate 500 connected to the elevating member 300 by the rotary shaft 400 is lowered and lifted by the cooling plate 40 to the upper portion of the work table 20, So that the green cloth 60 is pressed and cooled.

That is, bubbles are prevented from being generated between the double-ply fabrics 60 due to immediate cooling after thermocompression of the fabric 60, and the adhesion is further enhanced.

FIG. 13 is a cooling-released state diagram of a hot press having an elevating operation and a rotation changing structure of the heating plate and the cooling plate according to the present invention,

The cooling plate 40 performing the cooling and pressing operation is returned to the upper position in the state where the cooling of the raw fabric 60 is completed as shown in Fig. 13 because the lifting cylinder 220 is operated, The rotary plate 500 is lifted with the elevation of the lifting member 300 to open the cooling plate 40 from the work table 20.

At this time, in the process of opening the heating plate 30, the fabric 60 is attracted to the work table 20, and is prevented from rising along the heating plate 30. [

Thereafter, in the state where the workbench 20 is opened, the fabric 60 having been subjected to the pressing operation is removed in a state in which the vacuum attraction force of the workbench 20 is released.

It will be appreciated that the heating plate 30 and the cooling plate 40 are returned to the initial preparation stage once a single thermocompression operation is completed by the above-described series of processes.

In the above-described series of processes, one cycle has been described for each process step. Actually, one cycle is continuously operated by the preset program. As described above, the heating plate 30 and the cooling plate 40 are lifted The elevating cylinder 220 for interrupting the rotation and the pivoting cylinder 620 for interrupting the pivoting are formed by the predetermined stroke distance.

In addition, the guide rod 800 is slid through the horizontal portion 120 of the support arm 100 during the lifting operation, thereby guiding the lifting and lowering of the guide rod 800.

Meanwhile, various pressing forces must be applied depending on the type and thickness of the fabric 60 in the course of performing the adhesion. This can be done by controlling the gap of the lifting cylinder 220.

5, the elevating cylinder 220 is configured to be elevated and lowered by the operation of a gap adjusting valve 211 formed at the upper end of the cylinder housing 210 of the elevating cylinder unit 200, The threaded rod 221 inserted into the inner female threaded portion 211a of the gap adjusting hole 211 is moved up or down depending on the direction in which the threaded shaft 211 is rotated.

For example, when the gap regulating opening 211 is controlled to be detoured, the tightening force between the female screw portion 211a and the screw rod 221 is given, and the lifting cylinder 220 is lifted upward, The elevating cylinder 220 is lowered and the heating plate 30 or the cooling plate 40 (not shown) coupled to the elevating member 300, And the work table 20 are adjusted so that the pressing force can be varied.

6, the rotation of the rotating shaft 400 is stopped for safety in releasing the air pressure for operating the lifting cylinder 220 and the rotating cylinder 620, .

That is, when the normal pneumatic pressure is applied together with the elevating cylinder 220 and the pivoting cylinder 620 according to the normal operation of the thermal press 1, the cylinder rod 931 is drawn out of the locking cylinder 930, And the tooth portion 922 of the stopper 920 is released from the tooth portion 911 of the ratchet wheel 910. This allows the rotation of the rotation shaft 400 to be normal .

On the contrary, when the air pressure is released, the cylinder rod 931 is pulled in freely, and at the same time, the tensile force of the locking interlock spring 940 formed at the other end of the stopper 920 acts to pull the other end of the stopper 920, At this time, the toothed portion 922 formed at the middle portion of the stopper 920 is engaged with the toothed portion 911 of the ratchet wheel 910 to prevent the rotation of the rotary shaft 400.

That is, the operation of the locking means 900 as described above stops operation when the pneumatic pressure supply to the elevating cylinder 220, the rotating cylinder 620, and the locking cylinder 930 is canceled due to a malfunction of the hot press 1, Operation and safety.

As described above, according to the present invention, the hot press having the elevating operation and the swinging replacement structure of the heating plate and the cooling plate is operated not by the swing operation but by the upper, lower lift and left and right turning operation, It is possible to shorten the operation time, and there is no element that threatens the worker in front of the worker, thereby securing the safety of the worker.
