Figure 2 is the overall layout of the surface section of the invented Taping machine, Figure 3 is the overall layout of the side section of the invented Taping machine, Figure 4 is the enhanced layout of the major sections of the invented Taping machine, and Figure 5 is the structural layout showing the operating condition of the invented Taping machine

The invention is in regards to the Taping machine for taping boundaries of the case requiring various colors of painting using head unit to apply covering tapes.

The head unit (H) of the Taping machine of the invention stores the covering tape (T) in rolled (R) condition and attaches to the case (C) on the surface of the case (C) that requires various colors of painting, in other words, by taping the covering tape (T) on the boundaries without moving off the line and at the same time, once the taping process is complete, the machine also cuts the tape and completes the process of taping effectively.

Here, the Taping machine of the invention is structured with major components of die (12), detecting bar (14), sensor bar (16), jig (10), close to jig (10) is transporting rod (22), changing table (20)(20') equipped with changing and clamping method, the secondary guardrail (33) set on the primary guard rail (24) of the changing table (20)(20') extruding on the supplementary table (30), installed on the secondary guardrail (33) of the supplementary table (30) and prepped with the primary and secondary sensors (44) (46), and transporting table (40) with head unit (H) riding up and down on the load rod (48a).

The jig (10) of the invention is et with the die (12) which the case (C) is loaded and equipped on both sides with primary and secondary detectors (14a) (14a¹) (16a) (16a¹) with detecting bar (14) and sensor bar (16).

On the jig (10), size of the case (C) is considered and die (12) with settling hole (12a) on the surface to support on 3~4 sides of the case (C) and the detecting bar (14) and the sensor bar (16) is prepped close to the die (12).

The detecting bar (14) and the sensor bar (16) detects the taping position and scope of the head unit (H), reacting to the detecting method of the transporting table (40) and to the primary and secondary sensors (44) (46), and on both sides, prepped with primary and secondary detectors (14a) (14a') (16a) (16a¹) and installed flatly with the case (C) loaded on the die (12).

Here, the primary detector (14a) (14a¹) limits the detecting sectors of the primary sensor (44) with narrow width on the upper section of the detecting bar (14) and the secondary detector (16a) (16a¹), detects the case (C) size situated on the die (12) through secondary sensor (46) prepped on both outer sides of the sensor bar (16) and sets the scope of transport for the transporting table (40) and for detailed description of the primary and secondary detectors (14a) (14a¹) (16a) (16a'), refer to description of transporting table (40) to come later.

For example, the detecting bar (14) is installed on the fixed plate (10b) of the jig (10) through space (14b), and its position is adjusted by the movement of the adjusting hole (15) and the elastic spring (15a) positioned on both sides.

The detecting bar (14), as shown in enlarged figure of Figure 1 , goes through the space (14b) and is adjustably fixed with bolt on fixed plate (10b) of the jig (10) and its position is adjusted by the movement of the adjusting hole (15).

The adjusting hole (15) must be installed, using precision measuring tool such as micrometer head (omitted from the drawings) and bolts (omitted from the drawings) attached to the detecting bar (14) and here, since the detecting bar (14) is constantly attached to adjusting hole (15) by the elastic spring (15a), the position adjustment of the adjusting hole (15) is done with high precision.

The jig (10) must be fabricated with consideration of the size of the case (C) which may be changed based on the die (12), and the positioning width and location of the detecting bar (14) and sensor bar (16) and to meet such changes, the jig (10) must be made to be attached and detached on the main body of the Taping machine. And since the setting of the case (C) is detected through the touch sensor (12b) positioned close to the setting hole (12a), when the case (C) is unloaded upon completion of the taping process, the head unit (H) of the Taping machine returns to original position.

The changing table (20) (20') of the invention is close to the outer section of the jig (10) and is effectively transported via transporting rod (22) and changing methods and is fixed with clamping method and on the hem is the primary guardrail (24).

The changing table (20) (20') is positioned on the sides of the jig (10) and installed on set of changing tables (20) (20') parallel to each other and through transporting bar (22) prepped with primary guardrail (24), it moves in and out.

The changing table (20) (20') is fabricated in square plate shape near the outer side of the jig (10) and prepped with, in length direction, at least 2 primary guardrail and is set with supplementary table (30). the changing table (20) (20'), for the setting of the head unit (H), in other words, for the initial setting of the overall size of the case (C) loaded on the jig (10), rides on the transporting rod (22) and slides. Here, the reacting changing tables (20) (20') is mutually connected and operates back and forth movement.

Here, for the changing method, the changing table (20) (20') is installed to meet racks (R) (R') and the racks (R) (R') are prepped with pinion (P) clamping each other so that the changing table (20) (20') is effectively transported riding on the transporting rod (22).

The changing method, as shown in Figure 2, the set of racks (R) (R') is installed to meet the facing changing tables (20) (20') but install pinion (P) between the rack (R) and the rack (R') so that both are effectively connected and operated.

Here, when one of the changing table (20) (20') is transported individually, the changing method formed with racks (R) (R') and pinion (P) and its reacting changing tables (20) (20') is simultaneously transported and the repositioning of the changing tables (20) (20') as per initial setting of the case (C) is made simple and fixed with clamping method.

Here, the clamping method is prepped with transporting rod of the changing table (20) (20') that supports a flange (23), and the stopping plate

\ 'i (23a) is locked/released through functions of the cylinder (S3) and the passive linkage (23b) and active linkage (23c) which is linked on the on the side of the a flange (23), and portion cut and elastic changing stopping plate (23a).

The method of the clamping, as shown in enlargement of Figure 3, a portion on the hem of the a flange (23) is cut and through unique elasticity, the lock/release of the transporting rod is done through transporting of the stopping plate (23a) and passive linkage (23b) through the motion of the cylinder (S3) of the set of active linkage (23b) on the stopping plate (23a).

In addition, the changing tables (20) (20') is installed on one of the two pivots that react to each other. In other words, select one set of changing tables (20) (20') from the facing 20 changing table or 20' changing table and regardless to the length, the width is adjusted and its interference of each other is prevented and comparably larger changing width is obtained so that taping of the various sizes of the case (C) is possible.

In addition, the supplementary table (30) of the invention is set on the primary guardrail (24) of the changing tables (20) (20') and is transported, and extrudes on the sides the secondary guardrail (33). On the upper section of the supplementary table (30), the secondary guardrail (33) is extruded towards the inner side where the jig (10) is installed and on the transporting table (40), it is set to allow slide transport, and is set on the primary guardrail (24) of the changing tables (20) (20') and moves back and forth.

Here, the movement method is done through the force of the servo motor positioned on both sides of the changing tables (20) (20') which rotates with a set of belt pulley (36a) (36b) and with belt (36), or through servo motor linked with screw nut (37a) and screw rod where the transporting of the screw nut (37a) in direct line is related through rotational force of the screw rod (37).

Such movement method should be done by considering the space of the movement and apply selectively so that individually moving changing tables (20) (20') and supplementary table does not interfere with each other when moving back and forth.

The transporting table (40) of the invention is installed on the secondary guardrail (33) of the supplementary table (30) and is prepped with primary and secondary sensors (44) (46) and is set with head unit (H) that rides up and down on the load rod (48a).

The transporting table (40), together with the supplementary table (30) transports back and forth on the changing tables (20) (20') and at same time sets on the secondary guardrail (33) on the supplementary table (30) and through the motion of the cylinder (S1), it slides in and outer direction.

The transporting table (40) is prepped with load rod (48a) length wise on its hem and with the supplementary block (48) set on the head unit (H) on the load rod (48a), it is installed to move up and down via cylinder (S2) and is equipped with primary and secondary sensors (44) (46) and detecting methods on the lower section of the transporting table (40).

Here, for the detecting method, the detecting roller (42) to meet the detecting bar (14) of the jig (10) is equipped and directs the taping position of the head unit (H). The detecting roller (42), extrudes to the lower section of the transporting table (40) through the supporter (42a) and is installed to meet the detecting bar (14) of the jig (10). Here, the taping process should be done through the head unit (H) while it is transported by the supplementary table (30) where the detecting roller (42) of the transporting table (40) is attached to the detecting bar (14) of the jig (10), but here, the taping area by the head unit (H) is controlled by the primary and secondary sensors (44) (46). The primary sensor (44) rides on the primary guardrail (24) of the supplementary table (30) and during transport, detects the primary detecting part (14a) (14a¹) of the detecting bar (14) and raises or lowers the position of the head unit, in other words, detects the actual taping area and the secondary sensor (46) detects the secondary detecting part (16a) (16a') of the detecting bar (14) and detects the back and forth moving area of the supplementary table by detecting the overall size of the case (C) loaded on the jig (10).

In addition, the transporting table (40) detects the primary guardrail of the changing tables (20) (20') positioned on both sides and is equipped with the limit sensors (40b) (40b¹) to detect the limits of back and forth movement. The limit sensor (40b) (4Ob') is prepped on both sides of the transporting table (40) and detects the transporting area of the supplementary table (30), in other words, it detects the limiting position of the transporting table (40) set with the hear unit (H). The large width or the small width in accordance to the size of the case (C) and the changing tables (20) (20') which setting is initialized and limit of the supplementary table's back and forth movement is continuously detected and prevents the crashing of the transporting table.

As shown in the enhancement shown in Figure 4, the load rod (SV) of the cylinder (S1) that transports the transporting table (40) is installed with the elastic spring (E) on the fixating plate (4Oa) of the transporting table (40) and forms small tension section and transports with the detecting roller (42) is in contact with the detecting bar (14) and the movement of the head unit (H) is prevented for precise taping of the covering tape (T).

The movements of the Taping machine of the invention will be explained with reference to the Figures 1 and 5.

First, the jig (10) fabricated to the size of the case (C) is installed on the Taping machine, changing tables (20) (20') is transported and the detecting roller (42) is attached to the detecting bar (14) and by locking the setting clamp (22a), the changing tables (20) (20') is fixed in its position and when the transporting table (40) returns back to its original position, the preparation is finished.

Then by loading the case (C) to interlock with the setting hole (12a) of the die (10), and turning on the start switch (omitted from the drawings), the transporting table will move forward via motion of the cylinder (S 1) and the detecting roller (42), attached to the detecting bar (14) of the jig(10) and transports riding on the primary guardrail (24) of supplementary table (30) and simultaneously, the head unit tapes the covering tape (T) onto the case (C).

For example, on the transporting table (40), the supplementary block (48) is lowered via operation of the cylinder (S2) as the primary and secondary sensors (44) (46) goes through the primary detecting part (14a) and secondary detecting part (16a), and each head unit (H) simultaneously tapes the various sides of the case (C) while transporting.

Then the primary and secondary sensors (44) (46) consecutively detects the primary detecting part (14a) and secondary detecting part (16a) and cuts the covering tape (T) and as the head unit (H) rises, it returns to original position with the transporting table (40). And when the case (C) is unloaded, the touch sensor (12b) detects this and after 3~5 seconds, the head unit (H) returns to starting position and repeats the taping process.

The Taping machine's jig (10), changing tables (20) (20'), supplementary table (30), transporting table (40), head unit (H), and primary moving parts of cylinder (S1) (S2) (S3), touch sensor (12b), fixating clamp (22a), limit sensors (40b) (40b¹), primary and secondary sensors (44) (46) are connected to the control box (omitted from the drawings) via circuits and controlled based on the set sequence. In addition, the on/off power switch, the start switch, and instant stop switch that stops the Taping machine in case of an emergency and other control keys (omitted from the drawings) is equipped.

The Figures 6 and 8 is the layout of an example model of the Taping machine. Here, the Figure 6 is the overall frontal layout of the example model of the Taping machine and Figure 7 is the overall side layout of the Taping machine shown in Figure 6 and Figure 8 is the overall surface layout of the Taping machine shown in Figure 6.

In Figures 6 or 8, installed on the lower section of the table (10a) prepped with the jig (10) and prepared with the setting hole (50a), and install the setting ball (51) to aforementioned setting hole (50a), and while set on the supporting roller (54) on one part of the index table (50) that rotates on the spindle (52) and transports riding on the primary guardrail (56a) and with the changing table (56) with secondary guardrail (56b) on its hem, while on the secondary guardrail (56b) of aforementioned changing table (56), together with the load rod (58a) and with transporting table (58) equipped with head unit (H), the aforementioned transporting table (58) is prepped and the detecting roller (42') is equipped to detect the outer sections of the jig (10).

The index table (50) is fabricated to the original plate shape and on the upper side, the jig (10) and table (10a) is installed and various supporting roller (54) is set, and rotates on the spindle (52) in the center, and prepped with various setting holes (50a) on the outside in fixed intervals.

The setting hole (50a) rotates by position setting ball (51) installed close to the index table (50), here the spinning force of the index table (50) is transferred by the movement gadget (55) linked with passivity gear (52a) on the spindle (52).

Here, the supporting roller (54) is formed to tape on the outer side and rotating pivot (54a) installed with slant on the center of the index table (50) is set so that it is able to rotate. The supporting roller (54) is a taping roller and to support the index table (50) set with the jig (10) and table (10a) is installed in various position in set intervals and rotates centered on rotating pivot (54a)

The rotating pivot (54a) is installed with a slight slant angle (aes)on the center of the index table (50), here, the slant angle (afe) of the rotating pivot (54a) is changed based on the diameter and positioning of the supporting roller (54).

Here, there's an added benefit of preventing slipping friction, of the supporting roller (54) while attached to the lower portion of the index table (50) and in rotation, extending the life span. And install the changing table (56) prepped with a set of primary guardrail (56a) parallel aligned to aforementioned index table (50), and aforementioned changing table (56) moves back and forth through movement parts, and is equipped on the upper side with the secondary guardrail (56b) and transporting table (58).

The transporting table (58) is installed to ride up and down through the motion of the cylinder (S1) and load rod (58a) on the head unit (H) on one side and through movement parts, rides on the secondary guardrail (56b) and moves back and forth.

The transporting table (58) is prepped with detecting roller (42') on its lower section, and the aforementioned detecting roller (42'), as shown in enhancement in Figure 7, rides on the outer part of the jig (10') and detects the taping position and transporting areas of the head unit (H).

Here, the movements is done through rotation of the set of belt pulley (59a) (59b) and the belt (59) moved through force of servo motor, and through force of aforementioned belt (59), the changing table (56) and transporting table (58) is moved back and forth.

In regards to operation, when operating the switch after loading the case (C) to the die (10'), the changing table (56) will move forward.

Then the detecting roller (42') on the transporting table (58) is in contact with the outer parts of the jig (10') and through the motion of cylinder (S1), the head unit (H) lowers and simultaneously, the transporting table rides on the secondary guardrail (56b) and tapes the covering tape (T) onto the case (C).

Then once the taping is complete on one side of the case (C), the head unit (H), returns to original position by changing table (56) and the transporting table (58), then the index table (50) is rotated at fixed angle (for example: 90 degrees) and rotates the case (C), and aforementioned process is repeated and tapes the various sides of the case (C).

As various sides of the case (C) is taped using the head unit (H) and through fixed angle rotation of the index table (50), the cycle time may be increased, reducing productivity, but since the cost of the Taping machine is low, there's effect of reduction in facility investment.

The table (10a) installed on the index table (50) should consider the supplying and delivering process of the case (C), loaded/unloaded by the jig (10'), and fabricate one side in flat shape.

Jig (10') is installed on the table (60) that transports back and forth by the cylinder (S1) riding on the primary guardrail (62), with one set of die (12') installed so that it is able to rotate on the hem in roller shape, here the motion force is transferred to die (12') through reducer (R) linked to driving servo motor.

On the upper section of the jig (10'), head unit (H) is installed, here the head unit (H) is set on the transporting table (66) that transports back and forth riding on the load rod (66a) on the supporter (64) attached to a part of the table, and riding on the secondary guardrail (68), it moves up and down via movements of the cylinder (S2).

In regards to operation, after setting the circular shaped case (C") to a set of die (12') and pressing the start switch, the table (60) will ride on the primary guardrail through motions of the cylinder (S1), the head unit (H) will go through the load rod (66a) and the secondary guardrail (68) to taping position, in other words, attach to the surface of the case (C"), and through the motions of the drive servo motor, the reducer (R) will move and set of die (12') will rotate.

Then the circular shaped case (C") will link with the set of die (12') and the taping process will be conducted and once the process is complete, the drive servo motor will halt and when the table (60) rides on the primary guardrail (62) and the covering tape (T) is cut in unloading status, the taping process is complete.

As such, by fabricating the die (12) in roller shape and rotate the case (C") and conduct the taping process, the difficult manual taping process of circular shaped case (C") is automated and increases not only the productivity but prevents the bending (for example, the situation where the taping is done with the covering tape (T) in bent condition) of the covering tape (T) and results in high reduction of the defective rate.

The Figures 12 and 14 is different example model of the invented Taping machine and is described using aforementioned Taping machine and will only describe different sections.

When explaining with reference to the Figures, on the outer front section of the jig (10) set with the die (12) where the case (C) is loaded is prepped with the table (200), and on top of the fixed table (200) in length direction are the ball screw (210), which rotates through servo motor (M) and are the actual parts to move each blocks, and on top of the ball screw (210) is attached operation table (211) to allow movement.

And is installed near the exterior of the jig (10), excluding the fixed table (200), prepped with changing table (20) (20') with ball screw (210), which rotates through servo motor (M) in length direction, and also supplementary table (30) that can move along the ball screw (210).

Unlike the previously mentioned Taping machines, the movement is done not through the belt and pulley motion but through servo motor(M) and the operation table (11) linked to its rotating ball screw (210) which causes various blocks in each directions.

When using the ball screw (210) and the operation table (211) as the force of drive, error caused by slippage when using belt or pulley can be reduced and as a result, more precise control of each part is possible.

On the inner front section of the aforementioned fixed table (200) and changing table (20) (20') are numerous guardrails (110). To detect fixed table (200) and changing table (20) (20') while in motion, numerous sensor plates with various detecting parts are installed.

On the inner side of the changing table (20) (20') is the supplementary table (30) with ball screw (210) that rotates via servo motor (M), and installed on the ball screw (210) of the supplementary table (30), the lower section is prepped with detecting methods and the primary and secondary sensors (44) (46), with transporting table (40) set with the head unit (H) that rides up and down on the limit rail; and centered on the transporting table (40), a tilting method is formed to link the head unit (H) on slight angle of slant.

On top of the aforementioned die (10), in other words, on the section where the case (C) is settled and or is close to, start block (310) is installed, since this start block (310) does not provide stable initial contact when attaching on the case (C) with low adhesiveness through head unit (H), more freer adhesion is achieved through the head unit (H) by taping the case (C) and nearby start block (310) first.

In addition, the head unit (H) has sub roller (320) and main roller (330) that is each able to rotate on its pivot and support, the sub roller (320) conducts slight pressure when adhering the tape onto the case (C), the main roller (330) conducts heavy pressure when adhering the tape, preventing rising or distorting conditions.

When viewing the detailed structure of aforementioned tilting method, it is pivoted and supported to allow slight angled rotation of the portion of the transporting table, with changing plate (400) equipped with fan like angler (410) on the side installed through changing plate (400) on the aforementioned angler of the changing plate, and adjustment screw (420) to maintain the changing angles between the changing plate and the transporting table is installed

Here, same effect can be achieved by using precision controller such as micro meter and not going through the adjustment screw (420).

Therefore, when conducting the taping process with the front section of the case (C) is slightly angled and the angle of the head unit (H) is adjusted using tilting method, stable taping process can be achieved.

To explain in more detail, by fine tuning the angle using adjusting screw (420) and maintaining such angel through setting bolt located on the upper section of the angler (410), overall precise angle adjustment of the head unit (H) is possible.

In other words, the taping process is not only possible on flat surface but also on slightly angled areas as well.

The invention is not only limited to aforementioned examples, and without varying from the idea and scope of the invention, the various ways of adjusting and modifying the invention can be possible to anyone with general knowledge in this technical field. Therefore, such modified examples of the invention should also be included within the scope of the patent.

Above was the description of specific examples of the invention but the invention should not be limited to aforementioned examples and within the demanded scope, without varying from the importance of the invention, anyone with general knowledge in technical field that includes this invention may modify in various ways.
