[Problems to be Solved by the Invention]

In addition, in the technology described in Patent Document 1, there is a possibility that slippage may occur between the carrier tape (CT) and the roller (102, 103, 104, 105, 107, 109, 110). The sliding direction is the length direction of the carrier tape (CT) or the width direction of the carrier tape (CT). If the sliding occurs between the carrier belt (CT) and the roller (102, 103, 104, 105, 107, 109, 110), the conveying distance or position of the carrier belt (CT) cannot be accurately controlled.

Therefore, there are cases where a carrier tape having a plurality of perforations is used. These feeding holes are arranged in the length direction of the carrier belt. The carrier belt is hung on the sprocket, and the feeding holes are engaged with the teeth of the sprocket. If the sprocket is rotationally driven by the motor, the carrier belt is carried. However, there is a backlash between the feed hole and the teeth of the sprocket. Due to the backlash, there is a risk that the sprocket will idling slightly with respect to the carrier belt. In particular, there is the delivery of the carrier tape from the supply reel, the take-up of the carrier tape for recycling the reel, and the take-up of the cover tape of the take-up reel. The risk of sprocket idling. If such idling occurs at the end of the feeding of the carrier tape, the conveying distance and position of the carrier tape cannot be accurately controlled.

Therefore, the present invention has been made in view of the foregoing circumstances. The problem to be solved by the present invention is to suppress the occurrence of idling with respect to the sprocket of the belt even if there is a backlash in the engagement between the feeding hole of the belt and the teeth of the sprocket.

[Means to solve the problem]

In order to solve the above-mentioned problem, the tape peeling device is characterized in that it includes a feed motor that feeds a laminated tape, and the laminated tape is formed by attaching a cover tape to a base tape and is rolled The winding and peeling section peels the cover tape from the base tape of the laminated tape sent by the feeding motor; and the first winding motor winds the peeled tape by the peeling section. The aforementioned base tape; and a second winding motor for winding the aforementioned cover tape that has been peeled by the peeling section, and the aforementioned layer on the path of the laminated tape from the feed-out motor to the peeling section. The tension of the pressing belt is set to be smaller than the sum of the tension of the base tape wound by the first winding motor and the tension of the cover tape wound by the second winding motor. And bigger.

According to the above configuration, since the tension of the laminated belt is greater than the sum of the tension of the base belt and the cover belt, it is possible to suppress the occurrence of the idler of the sprocket due to the backlash. This matter contributes to the stable transportation of the laminated tape, the base tape, and the cover tape.

The motors 21, 31, 41, and 51 are servo motors. The rotation speeds of these motors 21, 31, 41, and 51 are servo-controlled by the control unit 81. The control unit 81 includes a servo amplifier, a programmable logic controller, and the like.

The carrier tape 1 is fed from the reel 20 toward the guide pulley 22. The carrier belt 1 is guided in the order of the guide pulley 22, the tension pulley 23, and the guide pulley 24, and is hung on these pulleys 22 to 24. The carrier tape 1 is guided from the guide pulley 24 through the space between the guide member 61 and the peeling member 62 and is guided under the take-out opening 64. The cover tape 3 is folded back by the end portion 63 of the peeling member 62 that becomes the edge of the take-out opening 64, and thereby the cover tape 3 is peeled from the base tape 2.

The stripped cover tape 3 is guided in the order of the guide pulley 66, the guide pulley 44, the tension pulley 43, and the guide pulley 42 and is covered with these pulleys 66, 44-42. on. The cover tape 3 is guided from the guide pulley 42 toward the reel 40.

The base belt 2 is guided from the guide pulley 32 toward the reel 30.

By having the base belt 2 be hung on the sprocket 52, the teeth 53 of the sprocket 52 are inserted into the feed hole 5. The teeth 53 of the sprocket 52 are hooked at the feed hole 5, and the sprocket 52 is rotated and driven by the drive motor 51, and the stripped base tape 2 is conveyed. Therefore, the pocket 4 and the IC chips 6 on the inside thereof sequentially pass below the take-out opening 64.

With the transfer of the base tape 2, the carrier tape 1 is carried in a direction from the guide pulley 24 to the sprocket 52.
The carrier tape 1 is sent out from the reel 20 by rotating the reel 20 by the sending-out motor 21 for rotation. By rotating the reel 30 by the first winding motor 31, the base tape 2 is wound by the reel 30. When the reel 40 is driven to rotate by the second winding motor 41, the cover tape 3 is wound by the reel 40.

During the operation of the drive motor 51, the output signal of the encoder provided at the drive motor 51 is fed back to the control unit 81. The control unit 81 controls the drive motor 51 based on the output signal of the encoder. Specifically, the control unit 81 controls the rotation speed of the drive motor 51 to be constant. As a result, the belts 1 to 3 are fed at a constant speed V. That is, the conveying speed V of the belts 1 to 3 is determined by the drive motor 51.

In addition, there is a backlash between the teeth 53 of the sprocket 52 and the feed holes 5 of the base belt 2. In the operation of the drive motor 51, there is a possibility that some idling may occur due to the backlash with respect to the sprocket 52 of the base belt 2. In order to prevent this kind of idling, the tension T1 of the carrier tape 1 is greater than the tension T2 of the base tape 2, and the tension T1 of the carrier tape 1 is more than the sum of the tension T2 of the base tape 2 and the tension T3 of the cover tape 3. A little bigger.

4. Tension control carrier tape 1, carrier tape, base tape, and cover tape. A certain tension T1 is applied to the path between the reel 20 and the peeling member 62 by the first tension applying portion 29. The peeled base tape 2 is connected to the path between the sprocket 52 and the reel 30, and is given a certain tension T2 by the second tension applying portion 39.

The first tension applying portion 29 includes a tension pulley 23, a linear guide member 25, and an air cylinder 26. The air cylinder 26 is attached to the machine frame 11 near the guide pulley 25. The rod of the air cylinder 26 extends downward from the body of the air cylinder 26 and is connected to the tension pulley 23. The tension pulley 23 is provided so as to be rotatable with respect to the rod of the air cylinder 26.

The body of the air cylinder 26 is supplied with high-pressure air by a compressor. An electric air conditioner 27 is provided in the middle of the piping from the compressor to the main body of the air cylinder 26. The electric air regulator 27 is controlled by the control unit 81 to control the supply pressure to the air cylinder 26 to be constant.

The high-pressure gas is supplied to the air cylinder 26 through the electric air regulator 27. The air cylinder 26 pushes the tension pulley 23 downward. As a result, the tension T1 which is in opposition to the load applied by the air cylinder 26 is applied to the carrier tape 1. Since the supply pressure to the air cylinder 26 is controlled by the electric air regulator 27, the load of the air cylinder 26 which pushes the tension pulley 23 downward is controlled to be constant. The tension T1 is also controlled to be constant.

The second tension applying section 39 includes a tension pulley 33, a linear guide member 35, and an air cylinder 36. The air cylinder 36 is attached to the casing 11 near the guide pulley 35. The rod of the air cylinder 36 extends downward from the body of the air cylinder 36 and is connected to the tension pulley 33. The tension pulley 33 is provided so as to be rotatable with respect to the rod of the air cylinder 36.

The body of the air cylinder 36 is supplied with high-pressure air by a compressor. An electric air conditioner 37 is provided in the middle of the piping from the compressor to the body of the air cylinder 36. The electric air regulator 37 is controlled by the control unit 81 to control the supply pressure to the air cylinder 36 to be constant.

The high-pressure gas is supplied to the air cylinder 36 through the electric air regulator 37, and the air cylinder 36 pushes the tension pulley 33 downward. As a result, the tension T2 which is in opposition to the load applied by the air cylinder 36 is applied to the base band 2. Since the supply pressure to the air cylinder 36 is constant, the load of the air cylinder 36 pushing the tension pulley 33 downward is controlled by the electric air regulator 37 to be constant, and the tension T2 of the base belt 2 It is also controlled to be constant.

The third tension applying section 49 includes a tension pulley 43, a linear guide member 45, and an air cylinder 46. The air cylinder 46 is attached to the machine frame 11 near the guide pulley 45. The rod of the air cylinder 46 extends from the body of the air cylinder 26 to the right and is connected to the tension pulley 43. The tension pulley 43 is provided so as to be rotatable with respect to the rod of the air cylinder 46.

The body of the air cylinder 46 is supplied with high-pressure air by a compressor. An electric air conditioner 47 is provided in the middle of the piping from the compressor to the main body of the air cylinder 46. The electric air regulator 47 is controlled by the control unit 81 to control the supply pressure to the air cylinder 46 to be constant.

The high-pressure gas is supplied to the air cylinder 46 through the electric air conditioner 47. The air cylinder 46 pushes the tension pulley 43 toward the right. As a result, a tension T3 that is in opposition to the load applied by the air cylinder 46 is applied to the cover tape 3. Since the supply pressure to the air cylinder 46 is constant, the load of the air cylinder 46 which pushes the tension pulley 43 toward the right is controlled by the electric air regulator 47 to be constant, and the tension of the cover belt 3 T3 is also controlled to be constant.

5. Speed control of the feeding motor By driving the motor 51, the substrate belt 2 is transported at a constant speed, and the carrier belt 1 is also transported at a constant speed. Furthermore, since the carrier tape 1 is sent out by the feed motor 21, the winding diameter of the carrier tape 1 at the reel 20 is changed. The rotation speed of the sending-out motor 21 is controlled by the control unit so that the conveying speed V and the tension T1 of the carrier tape 1 are kept constant and the rotation speed of the reel 20 is also changed in accordance with the change in the roll diameter of the carrier tape 1. 81 was controlled. The rotation speed of the sending-out motor 21 is controlled in accordance with the detection result of the first position detection unit 28.

Here, the first position detection unit 28 is provided with an encoder or the like. The first position detection unit 28 detects the position of the tension pulley 23, and the control unit 81 controls the rotation speed of the feed-out motor 21 based on the detection position caused by the first position detection unit 28. Specifically, it is as follows.

The control unit 81 compares the detection position caused by the first position detection unit 28 with the first reference position. This first reference position is a point between the uppermost point and the lowermost point of the movable range of the tension pulley 23, and more specifically, is the midpoint between the uppermost point and the lowermost point. If the detection position is higher than the first reference position, the length of the path of the carrier tape 1 is shorter than the first reference length. On the other hand, if the detection position is lower than the first reference position, the length of the path of the carrier tape 1 is longer than the first reference length. The first reference length refers to the length of the path of the carrier tape 1 from the guide pulley 22 through the tension pulley 23 to the guide pulley 24 when the tension pulley 23 is positioned at the first reference position.

As a result of the comparison, when the detection position is higher than the first reference position, that is, when the length of the path of the carrier tape 1 is shorter than the first reference length, the control unit 81 The speed of the sending-out motor 21 is increased. When the detection position is located lower than the first reference position, that is, when the length of the path of the carrier tape 1 is longer than the first reference length, the control unit 81 causes the feed motor 21 slow down. When the detection position is equal to the first reference position, that is, when the length of the path of the carrier tape 1 is equal to the first reference length, the control unit 81 does not change the speed of the delivery motor 21 .

As described above, by making the control unit 81 perform feedback control on the rotation speed of the feed motor 21 based on the detection position caused by the first position detection unit 28, the tension pulley 23 is microscopically centered on the first reference position And shaking. However, macroscopically, the tension pulley 23 stays at a slightly constant position, that is, at the first reference position. In addition, by the above-mentioned general feedback control, the rotation speed of the feed motor 21 is microscopically changed at a high frequency, but macroscopically increased.

6. The speed control of the first take-up motor keeps the conveying speed V and tension T2 of the base tape 2 constant and also changes the winding diameter of the base tape 2 at the reel 30 to rotate the reel 30. The speed is changed. The rotation speed of the first take-up motor 31 is controlled by the control unit 81. The rotation speed of the first winding motor 31 is controlled in accordance with the detection result of the second position detection unit 38.

Here, the second position detection unit 38 is provided with an encoder or the like. The second position detection unit 38 detects the position of the tension pulley 33, and the control unit 81 controls the rotation speed of the first winding motor 31 based on the detection position caused by the second position detection unit 38. Specifically, it is as follows.

The control unit 81 compares the detection position caused by the second position detection unit 38 with the second reference position. This second reference position is a point between the uppermost point and the lowermost point of the movable range of the tension pulley 33, and more specifically, is the midpoint between the uppermost point and the lowermost point. If the detection position is higher than the second reference position, the length of the path of the base tape 2 is shorter than the second reference length. On the other hand, if the detection position is lower than the second reference position, the length of the path of the base tape 2 is longer than the second reference length. The second reference length refers to the length of the path of the base band 2 from the sprocket 52 through the tension pulley 33 to the guide pulley 32 when the tension pulley 33 is positioned at the second reference position.

As a result of the comparison, if the detection position is higher than the second reference position, that is, the length of the path of the substrate band 2 is shorter than the second reference length, the control unit 81 causes the first take-up motor 31 deceleration. On the other hand, if the detection position is lower than the second reference position, that is, the length of the path of the substrate band 2 is longer than the second reference length, the control unit 81 causes the first take-up motor 31 growth. When the detection position is equal to the second reference position, that is, when the length of the path of the base tape 2 is equal to the second reference length, the control unit 81 does not make the first winding motor 31 The speed changes.
By the general feedback control as described above, the tension pulley 33 stays at a slightly constant position, that is, at the second reference position.

7. The speed control of the second take-up motor keeps the conveying speed V and tension T3 of the cover tape 3 constant and also makes the reel 40 rotate in accordance with the change in the diameter of the cover tape 3 at the reel 40. In the speed change mode, the rotation speed of the second take-up motor 41 is controlled by the control unit 81. The rotation speed of the second winding motor 41 is controlled in accordance with the detection result of the third position detection unit 48.

Here, the third position detection unit 48 is provided with an encoder or the like. The third position detection unit 48 detects the position of the tension pulley 33, and the control unit 81 controls the rotation speed of the second winding motor 41 based on the detection position caused by the third position detection unit 48. Specifically, it is as follows.

The control unit 81 compares the detection position with the third reference position. The third reference position is a point located between the rightmost point and the leftmost point in the movable range of the tension pulley 43, and more specifically, it is a midpoint between the rightmost point and the leftmost point. If the detection position is further to the left than the third reference position, the length of the path of the cover tape 3 is shorter than the third reference length. On the other hand, if the detection position is further to the right than the third reference position, the length of the path of the cover tape 3 is longer than the third reference length. The third reference length refers to the length of the path of the cover tape 3 from the guide pulley 44 through the tension pulley 43 to the guide pulley 42 when the tension pulley 43 is positioned at the third reference position.

As a result of the comparison, if the detection position is more to the left than the third reference position, that is, the length of the path of the cover 3 is shorter than the third reference length, the control unit 81 causes the second take-up motor 41 slow down. On the other hand, if the detection position is further to the right than the third reference position, that is, the length of the path of the cover tape 3 is longer than the third reference length, the control unit 81 causes the second take-up motor 41 Growth rate. When the detection position is equal to the third reference position, that is, when the length of the path of the cover tape 3 is equal to the third reference length, the control unit 81 does not make the second winding motor 41 The speed changes.
By the general feedback control as described above, the tension pulley 43 stays at a slightly constant position, that is, at the third reference position.

8. Setting of belt conveying speed and tension During the operation of the drive motor 51, the conveying speed V of the base belt 2 and the tensions T1 to T3 of the belts 1 to 3 are controlled to be constant as described above. Before the operation of the drive motor 51, the user can input the set speeds of the base belt 2 and the set speeds T1 to T3 of the belt 1 through the input section 82, and the transfer speeds V and The tensions T1 to T3 of belts 1 to 3 are changed.

The input section 82 is a keyboard, a ten-key keypad, a touch panel, a mouse, a switch, a button, a rotary potentiometer, an operation panel, and the like. When the user operates the input unit 82, a signal corresponding to the operation content is output from the input unit 82 to the control unit 81. As a result, the control unit 81 obtains the set values of the conveying speed V of the base belt 2 and the tensions T1 to T3 of the belts 1 to 3.

After the setting value is input, the control unit 81 is a drive motor 21, 31, 41, 51 and electric air conditioners 27, 37, 47. At this time, as described above, the control unit 81 controls the rotation speed of the drive motor 51 to be constant so that the transport speed V of the base tape 2 becomes a set value. Further, the control unit 81 controls the supply pressure of the electric air conditioners 27, 37, and 47 to be constant so that the tensions T1 to T3 of the belts 1 to 3 become set values.

9. Beneficial effects
(1) As described above, the tension T1 of the carrier tape 1 is greater than the tension T2 of the base tape 2. The tension T1 of the carrier tape 1 is slightly larger than the sum of the tension T2 of the base tape 2 and the tension T3 of the cover tape 3. Therefore, it is possible to suppress the occurrence of the idling of the sprocket 52 relative to the base belt 2 caused by the backlash. This matter contributes to the stable transfer of the base tape 2 and improves the stability of the transfer speed and tension of the base tape 2 below the take-out opening 64. Therefore, the timing of the pocket 4 through the removal opening 64 and the removal timing of the content removal device 100 are reliably synchronized, and the IC chip 6 is reliably removed by the content removal device 100.

(2) The tensions T1 to T3 applied to the belts 1 to 3 by the air cylinders 26, 36, and 46 are constant. Therefore, the belts 1 to 3 are stably transported. The constant speed conveyance of the substrate belt 2 caused by the drive motor 51 is also stable, and the conveyance speed V of the substrate belt 2 is unlikely to be disturbed.

(3) Even if the tensions T1 to T3 with bands 1 to 3 are disturbed in general due to external disturbances, etc., the air cylinders 26, 36, and 46 and the tension pulleys 23, 33, and 43 are guided in a linear manner. The members 25, 35, 45 are displaced. This matter is to suppress the occurrence of the aforementioned situation.

(4) Even if the winding diameters of the belts 1 to 3 at the reels 20, 30, and 40 are changed, the rotation speed of the motors 21, 31, and 41 is adjusted by the control unit 81 in accordance with such changes in the winding diameter. And was controlled. In addition, the tension pulleys 23, 33, and 43 stay at slightly fixed positions without being displaced. Accordingly, the tension control of the tensions T1 to T3 of the belts 1 to 3 is set to high accuracy.

(7) The type of carrier belt 1 can be set to set the conveying speed V of the base belt 2 and the tensions T1 to T3 of the belts 1 to 3. For example, if the bonding strength between the cover tape 3 and the base tape 2 is high, the set values of the tensions T1 to T3 of the tapes 1 to 3 are set to be high. In this way, the peeling force of the cover tape 3 from which the cover tape 3 is peeled from the base tape 2 can be combined with the bonding strength to increase the strength. On the other hand, if the bonding strength between the cover tape 3 and the base tape 2 is low, the set values of the tensions T1 to T3 of the tapes 1 to 3 are set to low. In this way, the peeling force of the cover tape 3 from which the cover tape 3 is peeled from the base tape 2 can be adjusted to the bonding strength and reduced.
