Description

Squeegee lifting device for screen printing machine {SQUEEGEE LIFTING DEVICE FOR SCREEN TEXTILE PRINTING MACHINE}

The present invention relates to an improvement of a squeegee elevating device for printing screens for printing patterns of various colors on fabric paper, and in particular, connecting the squeegee moving body running along the guide rail with the auxiliary belt, the operating rod fitted to the squeegee moving body is the driving belt Is connected to, but the drive belt is connected to the operating pulley rotated by the operating motor, the auxiliary belt is connected to the sliding pulley which is selectively controlled rotation by the electromagnetic brake, the position of the squeegee moving body and the squeegee By making the exchange possible, it is possible to significantly reduce the power required for the running of the squeegee moving body.

In general, screen printing machines are used as a method for printing a pattern of various colors on textile paper.

The rough printing principle of the screen printing machine is to move the fabric paper intermittently at a certain distance so as to be located directly below the screen, and in the above state, the squeegee moving body moving left and right along the guide rail is moved up and down according to the moving direction of the squeegee moving body. By printing the printing foil supplied to the screen by the squeegee to print the pattern on the woven paper.

At this time, the pair of left and right squeegee connected to the squeegee moving body descends the squeegee located in the rear of the moving direction, so that the printing can be done by printing the printing arc located on the screen, and the squeegee located in the front rises to prevent the printing work. Do not become.

The means for selectively raising and lowering the squeegee is a pair of the operation cam is rotated left and right by the movement of the operating rod fitted to move the squeegee a certain distance to the squeegee moving body, the pinion gear is coaxially coupled to the operation cam is rotated As the rack gear moves up and down, the squeegee is selectively lifted.

During the operation, the squeegee moving body is completely moved to one side to complete the innal work, and then moves to the other side to perform another inlay work. It rotates at a certain angle, so the pinion gear connected to the coaxial is rotated so that a pair of rack gears are lifted and the squeegee located in the rear of the driving direction is lowered, and the squeegee located in the front is raised so that the squeegee is completely replaced and then the squeegee is completed. Allow the moving object to move.

In this case, in order to move only the operating rod inserted into the squeegee moving body by a certain distance while the squeegee moving body is stopped, an appropriate friction force must be maintained between the squeegee moving body and the guide rail, and a brake lining is installed on the squeegee moving body to provide the frictional force. Doing.

Therefore, since the frictional force of the brake lining is always maintained between the squeegee moving body and the guide rail, the motor for moving the squeegee moving body left and right is always driven under load, so the production cost increases because a motor having a large capacity is used. In addition, there was a disadvantage that not only wasted power wasted, but also the management trouble such as frequent check of the operation of the brake lining.

As a means for correcting the shortcomings of the device, the inventor has filed a patent application No. 2010-104373 and No. 2010-112749.

On the other side of the drive shaft 61, as shown in FIG. 7, the drive shaft 61 is extended through the connecting rod 66, and another end of the drive shaft 61 is provided with another squeegee drive box 60 ′. As in the squeegee drive box 60 configured in the fixed bracket 65, the electromagnetic brake 70, the sliding pulley 90 and the operation pulley 80 is installed, the operation pulley 80 and the sliding pulley 90 is connected to the drive belt 44 and the auxiliary belt 47 and then to the operating rod 40 and the squeegee moving body 30 as described above.

At this time, the connecting rod 66 connecting the drive shaft 61 is adjusted in accordance with the width of the fabric (C) to be printed, so if the printing width is wide, the connecting width 66 is long, and if the short is short.

As shown in FIG. 1, two guide pulleys 86 and 96 which guide the driving belt 47 and the auxiliary belt 44 are installed on the other support frame 11 ′, such that the operating belt pulley 80 and the sliding pulley ( The auxiliary belt 44 and the driving belt 47 that rotate by 90 are intended to be guided.

However, the squeegee lifting device to be provided in the present invention is a means for driving the squeegee moving body 30 is made by the operating rod 40 connected to the operating pulley 80 and the drive belt 44, the squeegee moving body 30 Sliding pulley 90 is connected to the auxiliary belt 47 and the rotation is temporarily stopped by the electromagnetic brake 70, in this process the position of the squeegee 50, 50 'is made.

The driving process of the squeegee moving body 30 and the elevating process of the squeegee 50 of the present invention will be described.

First, when the driving motor (M) is driven, the driven pulley (62) connected to the drive pulley (63) and the belt (64) rotates, and thus, the drive shaft (61) rotates and the operating pulley (80) coupled to both sides and sliding. The pulley 90 is rotated.

At this time, the sliding pulley 90 is freely moved and rotated freely on the drive shaft 61, but the engaging rod 91 protruding on one side of the sliding pulley 90 is fitted in the long hole 81 configured at the side of the working pulley 80. In the state is located at the left end 81-1 of the long hole 81 as shown in Figure 9 so that the sliding pulley 90 is rotated together with the working pulley 80, and thus the printing arc 100 is as shown in FIG. Likewise printed on the fabric (C) by one side squeegee (50).

When the squeegee 50 moves in the direction of the arrow A in the same manner as described above, the squeegee moving body 30 moves in the opposite direction to the arrow A by driving the operating motor M in the control box in the same manner as in the conventional method. In this case, one side squeegee 50 is raised, the other side squeegee 50 'is to be lowered, the lifting and lowering of the squeegee 50, 50' to the sliding pulley 90 and the electromagnetic brake 70 Is made by.

That is, when the movement of the squeegee moving body 30 is completed in the direction of the arrow A, the operating motor M is rotated in reverse to move the squeegee moving body 30 in the opposite direction to the arrow A. At this time, the electromagnetic brake 70 When the magnetic force is generated by supplying power, the sliding pulley 90 slidably fitted to the drive shaft 61 is in close contact with the electromagnetic brake 70 while compressing the return spring 73, thereby sliding the pulley 90 and the auxiliary belt 47. ) Is temporarily stopped, and thus the movement of the squeegee moving body 30 is paused.

Since the operation pulley 80 continues to rotate along the drive shaft 61 even in the above state, the driving belt 47 connected to the operation pulley 80 moves in the opposite direction to the arrow A, so that the squeegee moving body 30 Only the inserted operating rod 40 is moved in the opposite direction to the arrow (A).

When the operating rod 40 moves in the opposite direction to the arrow A in the state where the squeegee moving body 30 is stopped as described above, the shaft rod 33 and the pinion gear by the operating cam 34 fitted to the operating rod 40. When the pinion gear 32 is rotated and the pinion gear 32 is rotated, the one side squeegee 50 is raised and the other side squeegee 50 'is lowered by the rack gear 52 coupled thereto.

In this case, it is possible to rotate the operating pulley 80 even when the sliding pulley 90 is controlled to be rotated by the electromagnetic brake 70. The squeegee moving body 30 is arrow A along the guide rail 20. The locking rod 91 protruding on one side of the sliding pulley 90 when moved in the direction is left end portion 81-1 of the long hole 81 in a state of being fitted into the long hole 81 of the working pulley 80 as shown in FIG. 9. When the state is located in, the rotation of the sliding pulley 90 is controlled by the electromagnetic brake 70 when moving in the opposite direction to the arrow (A), the operating pulley 80 in the opposite direction to the arrow (A) in the above state Even if it rotates, the rotation of the operating pulley 80 is problematic until the locking rod 91 of the sliding pulley 90 changes its position to the right end 81-2 of the long hole 81 of the operating pulley 80. Because it is not.

As described above, while the engaging rod 91 of the sliding pulley 90 reaches the right end portion 81-2 of the long hole 81 of the operating pulley 80, the squeegee 50 moves while the operating rod 40 moves. When the lifting and lowering of the 50 'is completed and the lifting and lowering of the squeegee 50 and 50' is completed, the power applied to the electromagnetic brake 70 is cut off so that the function of the electromagnet is terminated, so that the sliding pulley 90 returns the spring. The pulley 91 of the sliding pulley 90 is located at the right end 81-2 of the operating pulley 80 while being separated from the electromagnetic brake 70 by the 73. Along with 80 it is driven to rotate in the opposite direction to arrow (B).

Therefore, the squeegee 50 'prints the printing foil 100 on the fabric C as shown in FIG.

When the squeegee moving body 30 and the squeegee 50 'are completed in the opposite direction to the arrow A by the above means, the operating motor M is rotated again, and the electric brake 70 is turned on. The sliding pulley 90 is applied to the electromagnetic brake 70, and thus the movement of the squeegee moving body 30 connected to the sliding pulley 90 and the auxiliary belt 47 is paused.

However, since the operation pulley 80 is continuously rotated, the operating rod 40 connected to the drive belt 44 is moved in the direction of the arrow A, and the pinion gear 32 is moved by the operation cam 34 in the process. Rotate to swap squeegee 50, 50 'to position as shown in FIG.

In the above, the sliding pulley 90 can be rotated in the direction of the arrow (B) only the operation pulley 80 even when the rotation is controlled by the electromagnetic brake 70, the sliding pulley 90 as shown in FIG. Even if the operating pulley 80 is rotated in a state where the locking bar 91 is located at the right end 81-2 of the long hole 81 of the working pulley 80, the position of the locking bar 91 is long 81. It is possible to rotate by the distance to move to the left end 81-1 of the, and when the engaging rod 91 of the sliding pulley 90 reaches the left end 81-1 of the long hole 81, the electromagnetic brake ( The power supplied to the 70 is cut off so that the sliding pulley 90 is separated from the electromagnetic brake 70 to be driven together with the operation pulley 80 to print the squeegee moving body 30 along the guide rail 20. Work will be done.

As described above, in the present invention, the operating pulley 80 and the sliding pulley 90 are installed on the drive shaft 61 rotated by the operating motor M, and the sliding pulley 90 has the electromagnetic brake installed on one side. By the 70 to stop the squeegee moving body 30 when the driving direction is changed, the sliding pulley 90 is connected to the squeegee moving body 30 through the auxiliary belt 47, the operation pulley 90 By being connected to the operating rod 40 through the drive belt 44, the rotation of the sliding pulley 90 is temporarily stopped by the electromagnetic brake 70 when the driving direction of the squeegee moving body 30 is changed, the squeegee moving body ( 30 is stopped for a while, and the operation pulley 80 continues to rotate even in the above state so that only the operating rod 40 connected to the driving belt 44 is moved in the driving direction, and the operating rod 40 is moved. In the process, the squeegee (5) is operated by the actuating cam 34 and the pinion gear 32. 0) The position of 50 'is exchanged and then printing is performed.

As the printing operation is performed by repeating the above operation, the power required for the movement of the squeegee moving body can be reduced by removing a separate brake device on the squeegee moving body as in the prior art, thereby significantly reducing the power consumption of the screen printing machine.
