Description

TECHNICAL FIELD [0001] The present invention relates to a sheet peeling method and a sheet peeling apparatus,

The present invention relates to a sheet peeling method and a sheet peeling apparatus.

A method and apparatus for peeling a carrier film from a ceramic green sheet are disclosed in Japanese Patent Application Laid-Open No. 2000-252161 (Patent Document 1). In Patent Document 1, a ceramic green sheet held on a carrier film and conveyed is heated by a rotatable heating roll, pressed against a laminate on a table, and pressed. The laminate thus pressed by the ceramic green sheet is transferred to the peeling area, and the carrier film is turned from the ceramic green sheet by turning the carrier film at a predetermined angle with the direction changing contact jig as a fulcrum.

Japanese Patent Application Laid-Open No. 2000-252161

In Patent Document 1, it is necessary to perform an operation such as returning the table moved in the carrying direction to the original position, and the lamination process or the like which has been performed continuously until that time is not performed. Therefore, the operation such as transportation must be intermittent. The intermittent operation is hereinafter referred to as " intermittent operation ". When the intermittent operation is performed, it is necessary to stop the peeling mechanism or reduce the conveying speed. When the transport operation is stopped or decelerated, a certain time is required to return to the normal speed. There is a possibility of causing a problem in peeling off carried out until returning to the normal speed. In other words, since the peeling is performed at a speed lower than a predetermined conveying speed, the peeling state may be different from that originally planned, which may cause problems.

Patent Document 1 discloses an example in which the peeling step is intermittent due to the step of returning the table after the peeling step as described above. For example, when a sheet having a long carrier film is conveyed, it is necessary to perform an intermittent operation such as a printing process (the time required for printing is stopped) before the peeling process There may be a case where the progress of conveyance for the peeling process becomes an intermittent operation by carrying out the process of the kind not provided.

Patent Document 1 discloses peeling off a carrier film from a ceramic green sheet, but it is not limited to a case where a ceramic green sheet is desired to be peeled off, but also includes other types of sheets. .

When carrying out the intermittent operation, the sheet having the carrier film adheres to the region where the peeling of the carrier film progresses at a speed lower than the originally scheduled conveying speed Occurs. Since there is a possibility that a problem has occurred in these areas, these areas are treated as being defective areas. Those obtained by peeling off from these defective areas can not be employed as products. The increase in defective area leads to deterioration of product yield and increase of production cost.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a sheet peeling method and a sheet peeling apparatus capable of reducing a region to be a defective region as much as possible.

In order to attain the above object, a sheet peeling method according to the present invention is a sheet peeling method comprising the steps of: transferring a first sheet having a long shape attached to a surface of a substrate having a long or sheet- A first step in which the first sheet is continuously peeled off from the base material at a bifurcation point where the first sheet and the base material are divided in different directions and a second step in which the conveying speed of the base material A second step of decelerating or stopping the substrate at a speed lower than the first speed and a second step of moving the substrate in a second direction opposite to the first direction to relatively displace the branch point in the first direction And shifting the bifurcation in a second direction relatively opposite to the first direction in the base material By increasing the transport speed of the relative said base material from said branch point to the first rate over a fourth step of resuming the first step.

(Effects of the Invention)

According to the present invention, since the peeling is resumed by increasing the conveying speed by using the portion returned by the reverse conveyance as the entrance section, the ratio of the defective area can be reduced.

The dimensional ratio shown in the drawings does not necessarily mean faithfully and in reality, the dimension ratio may be exaggerated for convenience of explanation. In the following description, when referring to the concept above or below, it does not necessarily mean an absolute up or down but may mean relative up or down in the illustrated posture.

As an example of the problem that the peeling state is caused as a result different from the originally planned state due to the peeling at a speed lower than the original predetermined conveying speed, for example, the following can be cited. For example, in order to form conductor vias so as to penetrate the ceramic green sheet, the conductor paste is filled in the through holes formed so as to collectively penetrate the substrate and the ceramic green sheet in a state in which the carrier film as the base material supports the ceramic green sheet , And the substrate is peeled off from the ceramic green sheet. When the carrier film is peeled at a certain rate or more, the conductor paste remains properly in the through hole of the ceramic green sheet even after peeling off. However, when the carrier film is peeled off at an excessively low speed, there may occur a situation in which the conductor paste is pulled out from the through hole of the ceramic green sheet by the conductor paste inside the through hole of the carrier film. Therefore, there is a lower limit to the applicable peeling speed. This is merely an example of the problem, and there are many other cases where problems occur unless the removal rate is more than a certain level.

Hereinafter, the minimum speed necessary for normally peeling is treated as " first speed ".

(Embodiment 1)

(Sheet peeling method)

A sheet peeling method according to Embodiment 1 of the present invention will be described with reference to Fig. A flow chart of the sheet peeling method in this embodiment is shown in Fig.

The sheet peeling method in the present embodiment is a method in which a first sheet having a long shape is adhered to the surface of a base material having a long or sheet shape is conveyed in a first direction at a first speed or more, A first step (S1) in which the first sheet is continuously peeled from the substrate at a branching point which is divided in different directions, and a second step (S1) of carrying out the first step from the state where the first step is performed, A second step (S2) of decelerating or stopping the substrate so as to cause the substrate to move in a second direction opposite to the first direction, thereby displacing the bifurcation relative to the substrate in the first direction S3), and a second step of displacing the bifurcation point in a second direction opposite to the first direction relative to the base material In a fourth step (S4) to resume the first step (S1) the conveying speed of the base material by raising up to the first speed or higher.

In the first step S1, as shown in Fig. 2, a long sheet 1 is provided with a long first sheet 2 (hereinafter referred to as " first sheet 2 with a base material " Is conveyed in the first direction 81 and the first sheet 2 is continuously peeled off from the base material 1 at the branch point P2. In the example shown in Fig. 2, the first sheet 2 and the base material 1 are divided in different directions by the peeling rolls 21 and 22, and proceed. In the present embodiment, the first sheet with the base material is continuously conveyed from the previous step (for example, the printing step of the conductive paste) which is performed upstream, and intermittent operation (for example, printing operation) is performed in the previous step It is assumed that there is. Since the intermittent operation is performed in all the steps, intermittent operation is also generated in this subsequent step of peeling. Further, the present invention is not limited to the above-described situation, and the intermittent operation may occur in the peeling process by the intermittent operation after the peeling process. Further, the peeling process itself may be a case in which the intermittent operation must be performed for some reason.

The relationship between the conveying distance of the base material 1 and the conveying speed will be described as a typical graph.

3 shows a case in which the third step (S3) is not performed, unlike the sheet peeling method in the present embodiment for comparison. 3 is a comparative example. In this comparative example, the first step (S1) and the second step (S2) are performed, but the third step (S3) and the fourth step (S4) are not performed. In the section 301, the substrate 1 accelerates. In the section 302, the base material 1 is conveyed at a speed equal to or higher than the first speed. In this state, the peeling continues at the branch point P2. This step corresponds to the first step (S1). In the section 303, the substrate 1 decelerates. This step corresponds to the second step (S2). Thereafter, the speed is zero, but at this point, the substrate 1 is completely stopped. In the section 306, the substrate 1 accelerates again to exceed the first speed. In the section 307, the substrate 1 is again conveyed at a constant speed exceeding the first speed, The state continues. In this case, the area A in Fig. 3 is peeled while being conveyed at a constant speed exceeding the first speed, so that the first sheet 2 obtained by peeling can be employed as a product, Since the peeling is performed at a speed lower than the first speed, it becomes a defective area. Repeating the intermittent operation in this manner causes the area A and the area B to be repeated at an intersection, and thus the defective area is generated at a constant rate on the first sheet 2 obtained by peeling.

On the other hand, the sheet peeling method in this embodiment is as shown in Fig. In the section 301, the substrate 1 accelerates. In the section 302, as the first step S1, the base material 1 is transported in the first direction 81 at a speed equal to or higher than the first speed, and the peeling continues at the branch point P2. In the section 303, as the step S2, the conveying speed of the base material 1 is reduced to be less than the first speed. And finally the speed is zero. The substrate 1 is then transported in the second direction 82, as in sections 304 and 305. This corresponds to the third step (S3). P shown in Fig. 4 represents the machining pitch. As shown in the drawing, the third step (S3) is carried out by transporting the substrate 1 in the second direction 82. The third step (S3) performed in this manner is described in detail below.

For example, it is assumed that it is in the state shown in Fig. 5 at the boundary of the section 303 and the section 304. [ This is the state in which the second step (S2) is finished. The substrate 1 is transported in the first direction 81 until this state is reached, but at this point, the substrate 1 is stopped and the transport speed of the substrate 1 is zero. 5 shows a reference point P0, a separation point P1, and a branch point P2. The reference point P0 is a mark as a mark defined at a specific position on the base material 1 for convenience of explanation. When the base material 1 moves, the reference point P0 also moves. The peeling point P1 means a point between a section in which the peeling between the base material 1 and the first sheet 2 has already been performed and a section in which the peeling is not yet peeled. Up to this point, the peeling point P1 and the turning point P2 coincide with each other because the peeling has continued at the branching point P2 defined by the peeling rolls 21, 22. From this state, the base material 1 is transported in the second direction 82 as shown in Fig. The distance between the reference point P0 and the separation point P1 is kept constant and the reference point P0 and the separation point P1 move in the second direction 82. [ Since the branch point P2 is determined by the position of the peeling rolls 21 and 22 regardless of the movement of the base material 1, the position of the branch point P2 is not changed. As a result, Goes away from the peeling point P1. The base material 1 itself moves in the second direction 82 but the bifurcation P2 is displaced in the first direction 81 when viewed from the base material 1. In the sections 304 and 305 shown in Fig. 4, the branch point P2 is relatively displaced in the first direction 81 in the base material 1, which corresponds to the third step (S3). At the time when the section 305 is terminated in this way, as shown in Fig. At this point, the distance between the separation point P1 and the branch point P2 is the maximum.

Subsequently, in the fourth step (S4), the transfer speed of the substrate 1 is increased to the first speed or more while the branch point P2 is displaced in the substrate 1 relatively in the second direction 82, S1). This corresponds to the section 306 in Fig. In the fourth step (S4), the base material (1) accelerates while being transported in the first direction (81). The reference point P0 and the separation point P1 move in the first direction 81 while the distance between the reference point P0 and the separation point P1 is kept constant. The branch point P2 is displaced in the substrate 1 in the second direction 82 relatively. The branch point P2 approaches the release point P1 and finally the branch point P2 coincides with the release point P1. Up to this point, the conveying speed becomes equal to or higher than the first speed. In the section 307 in Fig. 4, the first step (S1) is again performed. The process up to the start of the section 307 is the fourth step (S4).

(Action / effect)

In this embodiment, the base material 1 is transported backward as shown in the sections 304 and 305 (see Fig. 4) in the third step (S3). In the fourth step (S4) , When the substrate 1 is reattached, the conveying speed is increased by using the portion already peeled and returned by the reverse conveyance as the acceleration section. The peeling is resumed by increasing the conveying speed. Therefore, in FIG. 4, the area B is smaller than in FIG. In other words, the ratio of defective areas is reduced.

According to the sheet peeling method in the present embodiment, it is possible to reduce the number of defective areas.

The sheet peeling method described in Embodiment 1 can be carried out, for example, by a sheet peeling apparatus described below.

For example, one apparatus may serve as a plurality of types of control units.

The transport apparatus 40 is provided with an unwinding roll 11. The sheet 1 and the first sheet 2 are superimposed one upon the other by rotating the unwinding roll 11 in the direction of the arrow 92 so that the first sheet adhered to the base material is directed toward the branching advancing device 13 .

According to the sheet peeling apparatus in this embodiment effect, the sheet peeling method described in Embodiment 1 can be easily performed. Therefore, it is possible to reduce the area which becomes the defective area as much as possible.

(Embodiment 3)

(Sheet peeling method)

The sheet peeling method according to the third embodiment of the present invention will be described with reference to Figs. 12 to 16. Fig.

The sheet peeling method in the present embodiment is a method in which a first sheet having a base sheet on which a first sheet of a long shape is attached on the surface of a base sheet in a long or sheet form is disposed in a direction in which the first direction is downstream The jig is brought into contact with one of the first sheet and the substrate so that the jig is bent in the first direction in the second direction in a direction opposite to the first direction, An A1 step in which the first sheet is continuously peeled off from the base material at a bifurcation point where the first sheet and the base material divide in different directions as the base material moves beyond a predetermined speed; A second step of decelerating or stopping the jig such that the relative moving speed is less than the first speed; A step A3 of relatively displacing the jig in the first direction by relatively displacing the jig in the first direction so as to displace the bifurcation relative to the base in the first direction; An A5 step of restarting the A1 process by accelerating the jig so that the jig starts moving in the second direction relatively to the jig in the second direction so as to be equal to or higher than the first speed, .

In the sheet peeling method according to the present embodiment, as shown in Fig. 12, a state in which the substrate 1 is brought into contact with the jig 16 to bend the substrate 1 is prepared. In this state, the substrate 1 is relatively stationary with respect to the stage 15. At this point in time, the substrate 1 may be stopped without being transported. Thus, the conveyance of the base material 1 is intermittent. In this stopped state, the stage 15 may fix the substrate 1 by forming any adsorption function on the upper surface of the stage 15, for example. In Fig. 12, a reference point P0 is shown for convenience of explanation. In Fig. 12, the state immediately before the peeling is started, and the peeling point P1 and the turning point P2 are at the respective positions. The reason for each position is thus clarified by the following description. The branch point P2 is located near the right end of the stage 15 in the figure. Then, the jig 16 is moved in the second direction 82. Tensile force is applied to the base sheet 1 and the first sheet 2 in the other direction with the bifurcation point P2 as a boundary and the peeling progresses due to the movement of the jig 16. The base material 1, Proceed to the upper left corner. The jig 16 may be, for example, a triangular prism extending in the direction immediately before the inside of the ground. The speed of the jig 16 toward the second direction 82 of the jig 16 when accelerated and viewed from the base 1 becomes equal to or higher than the first speed on the way. The jig 16 is moved in the second direction 82 so that the branch point P2 is displaced in the second direction 82 and reaches one of the peeling points P1. Thus, the state shown in Fig. 13 is reached. In Fig. 13, the separation point P1 and the branch point P2 coincide with each other.

The jig 16 is further moved in the second direction 82 at a speed equal to or higher than the first speed so that the separation point P1 and the branch point P2 are displaced in the second direction 82 do. At this time, the peeling of the base material 1 from the first sheet 2 proceeds. The process in which the peeling progresses above the first speed in this manner corresponds to the A1 process. Thereafter, the jig 16 lowers in speed and stops near the left end of the stage 15 in the figure. The process of decelerating and stopping in this way corresponds to the process A2. Thus, the state shown in Fig. 14 is obtained.

In the state shown in Figs. 13 to 14, the peeling point P1 coincides with the turning point P2. The first sheet 2 is in contact with the upper surface of the stage 15. Tensile force is applied to the base material 1 and the first sheet 2 in the directions indicated by arrows, respectively. Fig. 14 shows a state at the point of time when the peeling of one time has already been finished.

In the graph of Fig. 15, the conveying shape of the substrate 1 is indicated by a broken line, and the shape of the movement of the jig 16 is indicated by a solid line. The movement of the jig 16 in Figs. 12 to 14 corresponds to the broken line 503 in Fig. In the example shown in Fig. 15, the gap may be temporarily vacant until the bent line 502 starts after the broken line 503 is terminated, but may be continuously operated without spreading the gap.

As shown by a broken line 501 in Fig. 15, the base material 1 accelerates from a stationary state to a constant speed, advances by a predetermined time, and then decelerates to stop. At this time, as shown by a broken line 502, the jig 16 accelerates to a speed exceeding the base material 1 at all times, and advances at a speed higher than the speed of the base material 1 by a predetermined time. Therefore, it moves in the first direction 81 in a state in which the progress of the base material 1 is prevented. This shape is shown in Fig. The substrate 1 is transported in the first direction 81 but the jig 16 travels in the first direction 81 as indicated by the arrow 96 at the speed at which it is ahead. Whereby the branch point P2 is away from the peeling point P1. Here, the substrate 1 is transported in the first direction 81 corresponds to the step A4. The base material 1 is transported in the first direction 81 when proceeding from Fig. 14 to Fig. 16, so that the distance between the reference point P0 and the peeling point P1 is kept constant and the reference point P0 and the peeling point P1 Is moved in the first direction 81 along the upper surface of the stage 15. [ The bifurcation point P2 relatively moves in the first direction 81 from the peeling point P1 as viewed from the base material 1 as the jig 16 advances at a higher speed almost at the same time. Moving the branch point P2 in the first direction 81 from the separation point P1 thus corresponds to the A3 step. Some or all of the timing at which the third A3 process is performed and the timing at which the fourth A4 process is performed may be overlapped.

The jig 16 has been described as being faster than the conveying speed of the substrate 1 because the jig 16 is ahead of the substrate 1 and the speed of the jig 16 is higher than the conveying speed of the substrate 1. However, It is not necessary to proceed. Even if the traveling speed of the jig 16 is not faster than the feeding speed of the substrate 1, for example, the jig 16 starts to advance from the earlier stage than the substrate 1, The branch point P2 can be moved in the first direction 81 rather than the peeling point P1 by continuing the process to a time slower than the base material 1 or by both of them.

Thus, the state shown in Fig. 12 is returned. 12, the separation point P1 and the bifurcation point P2 are relatively returned to the original position as viewed from the stage 15, but the reference point P0 is relatively shifted from the stage 15 in the first direction 81 ), The reference point P0 does not return to the initial position. Except that the position of the reference point P0 is different, the state shown in Fig. 12 is returned. In Fig. 12, the separation point P1 and the branch point P2 were separately located at the position where the A3 process was performed before Fig. 12. The jig 16 starts to move relatively in the second direction 82 as viewed from the base material 1 in the state shown in Fig. 12 and accelerates so as to be equal to or more than the first speed in the second direction 82, Is resumed. The process leading to the resumption of the A1 process corresponds to the A5 process. By repeating this cycle, the base material 1 is sent in the first direction 81 by a predetermined length, and the peeling advances by a predetermined length each time the jig 16 moves in the second direction 81.

(Action / effect)

The conveying speed of the base material 1 relative to the branch point P2 can be increased to the first speed or more by the movement of the jig 16 even if the substrate 1 itself is not conveyed in the reverse direction, The above peeling can be performed. Peeling is performed at a speed lower than the first speed for the section in which the speed of peeling has been reduced. However, since it is used as an acceleration section at the next time of acceleration due to the reciprocating movement of the jig 16 along the stage 15, can do.

(Sheet peeling device)

A sheet peeling apparatus according to Embodiment 4 of the present invention will be described with reference to Fig.

The sheet peeling apparatus 102 in this embodiment has a jig control device 20 and a transfer device 40 as shown in Fig. The jig control device 20 has a structure in which a first sheet to which a substrate having a long first sheet 2 attached on the surface of a base material 1 in an elongated or sheet- The jig 16 is brought into contact with the substrate 1 while the first sheet 2 and the substrate 1 are brought into contact with the jig 16 so that one of the first sheet 2 and the substrate 1 is bent along the jig 16. [ The first sheet 2 is moved in the second direction 82 which is the direction opposite to the first direction 81 as viewed from the first sheet 2, The sheet 2 is peeled from the base material 1. The transport apparatus 40 transports the first sheet to which the base material is attached in the first direction 81. The jig control device 20 has a jig 16 for determining the turning point P2 and a jig 16 for displacing the turning point P2 in the first direction 81 relative to the base 1 And a jig retraction control unit 46 capable of displacing the bifurcation point P2 in the substrate 1 in the second direction 82 at a first speed or more.

(Embodiment 5)

(Sheet peeling method)

A sheet peeling method according to Embodiment 5 of the present invention will be described. The sheet peeling method in this embodiment includes the same steps as the sheet peeling method described in Embodiment 1 and the like, but differs from the following point. In the sheet peeling method according to the fifth embodiment based on the present invention, at least one of the upstream side and the downstream side of the place where the first step (S1) is performed is applied to at least one of the substrate 1 and the first sheet 2 There is a first facility that performs the fifth process to be performed by the intermittent operation, and at the timing of performing the second process (S2), the fifth process is performed in parallel in the first facility.

(Action / effect)

In the present embodiment, the second step (S2) is performed so as to synchronize with the intermittent operation while performing the fifth step to be performed in the intermittent operation in the first facility.

The same can be said of the sheet peeling method described in Embodiment 3 or the like. That is, there is a first facility for performing an A6 process to be performed on at least one of the substrate and the first sheet by intermittent operation on at least one of the upstream side and the downstream side of the place where the A1 process is performed, And at the timing of performing the A2 process, the A6 process may be performed in parallel in the first facility.

(Embodiment 6)

(Sheet peeling method)

A sheet peeling method according to Embodiment 6 of the present invention will be described. The sheet peeling method in this embodiment includes the same steps as the sheet peeling method described in Embodiment 1 and the like, but differs from the following point. In the sheet peeling method according to the present embodiment, at least one of the substrate 1 and the first sheet 2 is subjected to the first step (S1) on at least one of the upstream side and the downstream side of the place where the first step (S1) (S6) to be processed by the intermittent operation or the continuous operation at the timing different from the fourth step (S4). The flow of the substrate is temporarily operated between the place where the second facility is placed and the place where the first step (S1), the second step (S2), the third step (S3) and the fourth step (S4) A buffer mechanism capable of stopping the buffer mechanism is disposed. At least one of the base material 1 and the first sheet 2 is carried through the buffer mechanism. The buffer mechanism may be a mechanism including any one of a compasser roll, a dancer roll, and the like. The buffer mechanism is, for example, a mechanism for temporarily storing the area of the base material 1 after the sixth step (S6) by the second facility, and then supplying the area toward the place where the first step (S1) is performed good.

(Action / effect)

In the present embodiment, there is a second facility for carrying out the sixth step (S6) to be processed by the intermittent operation or the continuous operation at different timings. However, since the buffer mechanism is disposed, the first step (S1), the second step The third process (S3) and the fourth process (S4) can be performed by the intermittent operation of the desired timing independently of the timing of the operation of the sixth process (S6) in the second facility. As a result, it is possible to reduce the area that becomes the defective area as much as possible.

A plurality of the above embodiments may be appropriately combined.
