2. Description of the Related Art FIG. 8 is an explanatory diagram showing a schematic configuration of a conventional taping device. As shown in FIG. 8, the taping device 1 has a storage tape 3 that is transported and moved between a tape feeding wheel 2a and a tape feeding wheel 2b. A timing belt 4 for transmitting power, which is maintained in tension by a tensioner 4a, is stretched between the tape feeding wheel 2a and the tape feeding wheel 2b.

[0005] The storage tape 3 is provided with a timing belt 4.
By the pitch feed operation of the tape feed wheel 2a directly connected to the drive motor 5 through the tape feeding wheel 5, the tape is sent out in the transport direction a (see the arrow in the drawing) from the tape feed wheel 2a to the tape feed wheel 2b. At this time,
A number of feed pins projecting from the outer peripheral surface of the tape feed wheel 2a and the tape feed wheel 2b at substantially equal intervals in the circumferential direction respectively enter and lock the respective feed holes provided in the storage tape 3. I do.

The storage tape 3 is embossed, and is provided with a plurality of storage recesses (emboss pockets) 3a which are open on the surface and are continuous in the longitudinal direction.

A tape rail 6 is provided between the tape feeding wheel 2a and the tape feeding wheel 2b. Above the storage tape 3 moving on the tape rail 6, a tape cover 6 is opened on a top cover 7 covering the storage tape 3. A suction nozzle 8 is installed facing the component insertion opening 7a. The suction nozzle 8 can suction and hold the electronic component E, and moves the storage tape 3 to move the component insertion port 7a.
When the storage concave portion 3a is positioned at the position, the electronic component E can be dropped by releasing the suction and holding, and the electronic component E can be stored in the storage concave portion 3a.

A sensor 9 for detecting the storage state of the electronic component E stored in the storage recess 3a is provided downstream of the component insertion opening 7a of the top cover 7 in the transport direction a.

The taping device 1 allows the storage tape 3 to move with the rotation of the tape feeding wheel 2a.
The electronic components E are sequentially and sequentially stored in the respective storage recesses 3 a via the suction nozzles 8.
The storage state of the electronic component E in each storage recess 3a can be confirmed.

As such a taping device, for example, an electronic component assembly covering tape winding device disclosed in JP-A-57-188900, and JP-A-5-29.
An electronic component supply device disclosed in JP-A-791 and a mounting method and a mounting device using a taping product of a semiconductor device disclosed in JP-A-6-21687 are known.

An electronic component assembly covering tape winding device includes: a storage tape in which a large number of concave portions for storing electronic components are arranged at equal intervals; an electronic component aggregate having a covering tape fixed to the storage tape and closing the concave portion; Means for transporting the electronic component assembly, support means for horizontally supporting the electronic component assembly with the covering tape facing upward, and covering tape provided near the take-out position of the electronic component and near the upper surface of the storage tape A take-up reel that is provided at a position opposite to the take-out position of the electronic component and takes up the covering tape; a support base that detachably and rotatably supports the take-up reel; and a lower part of the take-up reel. The take-up reel is always rotated by the take-up reel, with the tension of the take-up reel being greater than the force that peels off the covering tape from the storage tape and that does not break the covering tape. Comprising a take-up rotary shaft to provide a.

Further, the electronic component supply device has a dancing guide having a fulcrum shaft provided between a reel holding portion fixed to a main body frame and a carrier tape feed gear for transporting a certain amount of taping electronic components. Before the components are conveyed, a certain amount of taping electronic components is pulled from the reel.

[0012]

However, the above-described conventional taping device 1 can detect the stop position of the storage tape 3 but has a monitoring means for monitoring the moving state of the storage tape 3. Therefore, even if some trouble occurs during the movement of the storage tape 3 and the storage tape 3 enters an abnormal movement state, it cannot be dealt with.

The sensor 9 detects each of the storage recesses 3a.
Can be detected whether or not the electronic component E stored in the device 9 is stored as specified. However, since the installation position of the sensor 9 is away from the component insertion port 7a, the electronic component E is not stored as specified. Even if was detected, it was not possible to stop immediately upon storage.

As described above, when any abnormality occurs in the transport system of the storage tape 3 and an excessive load is applied to the storage tape 3, not only the storage of the electronic component E in the storage recess 3a becomes insufficient, but also In the worst case, damage such as breakage of the storage tape 3, breakage of the storage recess 3a, or deformation of the feed hole provided in the storage tape 3 will occur without breaking.

That is, in the transport system of the storage tape 3, when the electronic component E is inserted into the storage recess 3a in an incomplete posture or when the holding state during the insertion process is poor, the electronic component E is not stored in the storage recess 3a. 3a, it may cause excessive friction and interference with peripheral parts of the tape transport system, causing abnormal tape feeding. When the electronic component E interferes with a peripheral component, a compressive stress is generated at a local portion of the storage tape 3 and the stress is released with tape breakage.

Further, when the sprocket holes are deformed, the positioning of the electronic component E in the next process equipment is adversely affected. In particular, in the case of a high-speed apparatus in which taping is performed in less than 0.3 seconds per piece, since the feeding time of the storage tape 3 is as short as 0.1 seconds or less, the initial load becomes large at the start of tape feeding, and the torque of the drive motor 5 becomes large. Is also big. The power of the tape feed is
A large number of feed pins provided on the tape feeding wheel 2b are dispersed and transmitted to the feed holes of the storage tape 3, and if the tape feed is normal, no excessive load is applied to the storage tape 3.

However, if the storage tape 3 is clogged during transportation, power for feeding the tape is directly applied to the clogged storage tape 3, and the storage tape 3 is damaged by the resulting compressive stress. Since the electronic component E in the damaged storage tape 3 cannot be shipped as it is as a product, it is necessary to discard the electronic component E as it is already stored or to perform a re-taping operation with a great deal of time and effort. And

Such damage to the storage tape is also caused by the conventional electronic component assembly covering tape winding device, the electronic component supply device, and the mounting method and mounting device of the semiconductor device by taping under similar conditions. As a result, the electronic component E needs to be discarded or re-taped.

An object of the present invention is to prevent the storage tape from being damaged even if an excessive load is applied to the storage tape during the tape feeding of the electronic component, and to recover to a normal state even if a tape feeding error occurs. An object of the present invention is to provide an easy taping device and a driving method thereof .

[0020]

In order to achieve the above object, a taping device according to the present invention uses a drive motor.
The storage portion of the storage tape being transported moved between a first wheel and a second wheel, the taping apparatus for feeding and housing electronic components, and the first wheel and the second
The deviation of the driving amount from the wheel is out of the preset allowable value.
In this case, an abnormality detecting means for stopping the movement of the storage tape is provided.

With the above structure, the storage tape
Between the first wheel and the second wheel for transporting
Drive amount of deviation, if it is preset allowance values, the abnormality detecting means, Ru stops the movement of the storage tape. Thus, even if an excessive load is applied to the storage tape during the feeding of the electronic component to the tape, the storage tape is not damaged.

When the storage tape is bent,
Force the first wheel in the direction opposite to the tape feeding direction.
By reversely rotating the tape, it is easy to recover to a normal state even if a tape feeding error occurs.

[0023]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an explanatory diagram showing a schematic configuration of a taping device according to an embodiment of the present invention. As shown in FIG. 1, the taping device 10 includes a tape feeding wheel ( first wheel ) 11 and a tape feeding wheel ( first wheel ) .
Storage tape 1 conveyed and moved between two wheels 12)
Three. Between the tape feeding wheel 11 and the tape feeding wheel 12, a power transmission timing belt 15, which is maintained in tension by a tensioner 14, is stretched. The tensioner 14 can be fixed by the tension lock 16 in a state where the timing belt 15 has been bent.

The storage tape 13 is transported from the tape feed wheel 11 to the tape feed wheel 12 by a pitch feed operation of the tape feed wheel 11 directly connected to the drive motor 17 through the timing belt 15 (in FIG. (See arrow). At this time, a plurality of tape feed pins 18 projecting from the outer peripheral surfaces of the tape feed wheel 11 and the tape feed wheel 12 at substantially equal intervals in the circumferential direction are provided on the tape feeder provided on the storage tape 13. The holes 19 (see FIG. 5A) are respectively engaged and locked.

The storage tape 13 is embossed, and is provided with a plurality of storage recesses (emboss pockets) 13a which are open on the surface and are continuous in the longitudinal direction (see FIG. 3 (a)). ). The operation of the drive motor 17 is controlled by the control unit 20. This control unit 2
0 controls the operation of the solenoid 31 described later together with the operation of the drive motor 17.

A tape rail 21 is provided between the tape feeding wheel 11 and the tape feeding wheel 12, and the storage tape 13 moves on the tape rail 21. A first top cover 22 and a second top cover 23 are provided so as to cover the storage tape 13 so as to sandwich the storage tape 13 between the tape rail 21 and insert a component between the top covers 22 and 23. The mouth 24 is open. Above both top covers 22 and 23, a suction nozzle 25 is provided facing the component insertion port 24.

The suction nozzle 25 can hold the electronic component E by suction, for example, in a decompressed state. When the storage tape 13 moves and the storage recess 13 a is positioned in the component insertion port 24, the suction nozzle 25 performs suction holding. By releasing and dropping the electronic component E, the electronic component E can be stored in the storage recess 13a.

A component detection sensor 28 for detecting whether or not the electronic component E is stored in the storage recess 13a is installed on the second top cover 23 located on the downstream side in the transport direction a of the component insertion port 24. Have been. 1st top cover 2
2, on the upstream side in the transport direction a, above the storage tape 13 corresponding to the operation position of the tape push-up pin 30 described later,
A push-up confirmation sensor 29 that detects that the storage tape 13 has been pushed up is provided.

Below the tape rail 21, there is provided a solenoid 31 for vertically moving a tape push-up pin 30 to push up the storage tape 13 from below. The tape push-up pin 30 is provided at one end of a plate-shaped base 32 at a predetermined angle, and is formed in an L-shape integrated with the base 32. The base portion 32 is rotatably supported by a shaft 33 that penetrates a substantially central portion in the longitudinal direction, and the other end is provided on a lower side with a locking protrusion 34 a protruding from an upper end side of the operating portion 34 of the solenoid 31. From the lock.

A base locking projection 35 is formed at one end of the base 32 on which the tape push-up pin 30 is projected, and the base locking projection 35 is provided on a mounting surface 36 of the solenoid 31 mounted on the mounting surface 36. Return spring 38 with one end locked to stop 37
Is locked at the other end.

FIGS. 2A and 2B show the tape feeding wheel of FIG. 1, wherein FIG. 2A is a front view and FIG. 2B is a sectional view. As shown in FIG. 2, a rotation detector 41 including a rotation angle display cam 39 and an angle sensor 40 is provided on the tape feeding wheel 11.
(See (a) and (b)).

The rotation detector 41 is also provided on the tape feeding wheel 12. In the tape feeding wheel 11, the rotation detector 41 serves as a reference detector for detecting a reference rotation. , Function as a shift detector for detecting a shift with respect to a reference rotation. Hereinafter, the configuration of the tape feeding wheel 11 will be described, but the same applies to the tape feeding wheel 12.

The rotation angle display cam 39 is formed in a disk shape having an involute curved outer periphery whose distance from the rotation center changes according to the rotation angle (see (a)), and the rotation center of the tape feeding wheel 11 is determined. It is fixed to one end of the penetrating shaft 42 (see (b)). A rotating pulley 43 to which driving force is transmitted by the timing belt 15 and rotates is fixed to the other end of the shaft 42 (see (b)). This axis 4
2 is a tape feeding wheel 1 via a gear type index 44 in order to increase the resolution of the rotation angle display cam 39.
1 (see (b)) and the rotation angle indicating cam 39
The rotation corresponds to one pitch of the storage tape 13.

An angle sensor 40 is provided so as to sandwich the outer peripheral edge of the rotation angle display cam 39 (see (b)). The rotation of the rotation angle display cam 39 causes the diameter of the rotation angle display cam 39 passing through the angle sensor 40 to be different, and the amount of light shielding changes.
The rotation angle (drive rotation angle) of the rotation angle display cam 39 is detected as the feeding amount of the storage tape 13. That is, the rotation amount of the tape feeding wheel 11 directly connected to the drive motor 17 is detected as a reference rotation amount when comparing with the rotation amount of the tape feeding wheel 12.

The shift detector having the same configuration as the reference detector is a tape feed wheel 1 driven by a tape feed wheel 11 via a timing belt 15.
2, the feed amount of the storage tape 13 itself can be indirectly detected.

Each rotation amount obtained by the reference detector and the deviation detector is used as detection information by a control unit (comparison detection means) 2.
0, and is compared by the control unit 20 to determine whether or not a shift has occurred during the conveyance of the storage tape 13. In the case of displacement, it is presumed that a problem such as tape clogging occurs on the transport path of the storage tape 13 and a compressive stress is generated in a local portion of the storage tape 13.

If a problem such as tape clogging occurs when the storage tape 13 is transported, a compressive stress is applied to a local portion of the storage tape 13. When a compressive stress is applied to the storage tape 13, the storage tape 13 itself or the tape delivery wheel 12 is not fed by one pitch and is incompletely rotated with respect to the tape feeding wheel 11 which performs one pitch feeding operation regardless of occurrence of abnormality. State.

If there is no abnormality such as tape clogging, the rotation amount of the tape feeding wheel 11 and the tape position sensor 4
5, the feed amount of the storage tape 13 or the rotation amount of the tape feeding wheel 12 is the same at the same timing and the same amount. However, when there is an abnormality such as tape clogging, the rotation amount of the tape feeding wheel 11 and the rotation amount of the storage tape 13 or the rotation amount of the tape feeding wheel 12 detected by the tape position sensor 26 are changed. Timing and amount shift.

When a tape jam or the like occurs in the component insertion port 24 and a timing shift or a shift in the feed amount occurs in both the tape feeding wheel 11 and the tape feeding wheel 12, the tape feeding wheel 11 and the component insertion port 24 In the meantime, the storage tape 13 is bent by one pitch of the storage tape 13.

When the bending occurs, the tape push-up pin 30 is pressed against the portion where the bending occurs, and the bending generated in the storage tape 13 is held. This bending is caused by the fact that the storage tape 13 is not sent out, and a local portion causing the tape clogging is in a state where a compressive stress is generated. In an attempt to release the compressive stress, a force is applied to the storage tape 13 to move in the direction of the tape feeding wheel 12 with a low load.

At this time, if the storage tape 13 is sent out in an attempt to forcibly eliminate the tape jam, the storage tape 13 itself will be damaged. Therefore, if the tape push-up pin 30 is pressed against the bending of the storage tape 13 caused by tape clogging or the like to prevent the release of stress in the tape advancing direction, and if the stress is forcibly released in the opposite direction, the storage tape 13 Can be prevented from being damaged.

FIGS. 3A and 3B show the tape push-up pin of FIG. 1, wherein FIG. 3A is an explanatory diagram when the solenoid is not operated, and FIG. 3B is an explanatory diagram when the solenoid is operated. As shown in FIG. 3, when the solenoid 31 does not operate, the base 32, the other end of which is locked to the locking projection 34 a of the operating portion 34, is in a substantially horizontal state. It is almost in contact with the lower surface side (see (a)).

On the other hand, when the solenoid 31 operates, the
4 retracts and the locking projection 34a moves downward, the base 32 rotates clockwise about the shaft 33 against the urging force of the return spring 38, and pushes up the tape push-up pin 30. The storage tape 13 is pushed upward by the pushed-up tape push-up pin 30 (see (b)). The push-up confirmation sensor 29 detects that the storage tape 13 has been pushed up.

When the operating portion 34 advances and the locking projection 34a moves upward from the state in which the tape push-up pin 30 is pushed up, the base 32 is moved by the urging force of the return spring 38 to move the shaft 3 inward.
3, the tape push-up pin 30 returns to its original position, and the storage tape 13 returns to a substantially horizontal state before being pushed up (see (a)).

The amount by which the storage tape 13 is lifted depends on the distance between the tape feed pin 18 of the tape feed wheel 11 on the storage tape 13 and the end face on the entrance side of the first top cover 22, and is embossed at a pitch of 4 mm, for example. If each distance in the storage tape 13 is 120 mm, the lifting amount is about 7 mm.

It is important that the time required for lifting the tape is short. In the case of a taping device which completes the tape feeding operation in 0.1 second, it is necessary to operate the tape at about 10 ms after the detection. Use a responsive solenoid. The stroke of the operating portion 34 of the solenoid 31 is converted into the amount of pushing up of the tape pushing up pin 30 via the base 32 that rotates about the shaft 33.

When an abnormality is detected and the taping device 10 stops, the tape push-up pin 30
With the tape pushed up from below, the tape feeding wheel 1
Numerals 1 stop after being rotated by one pitch. At this time, the tension lock 16 is set so that the timing belt 15 is bent so that the tape feeding wheel 12 connected to the tape feeding wheel 11 via the timing belt 15 does not rotate.
Is fixed in the state where is operated.

When the tape feeding wheel 11 has already been rotated by one pitch and the tape push-up pin 30 has been actuated, it is necessary to return the excessively fed storage tape 13 by one pitch when the taping device 10 recovers its original state. Becomes Therefore, based on the operation command from the control unit 20, the reverse rotation operation of the tape feeding wheel 11 is performed by using the reverse rotation function of the drive motor 17.

That is, an abnormality occurs in the component insertion port 2
4 has many troubles, so the tape feeding wheel 11
Is rotated by one pitch in the reverse direction, so that the component insertion port 2
4 makes it possible to see the storage recess 13a in which the problem has occurred, facilitating the recovery of the original state before the occurrence of the abnormality.

The solenoid 31, the base 32, the tape push-up pin 30, the return spring 38, the drive motor 17, and the control unit 20 force the compressive stress generated in the storage tape 13 in the direction opposite to the tape feeding direction. It functions as a stress release part to release. Further, the driving motor 17 having the reversing function enables the feeding wheel 11 to be reversed by one pitch so that the taping device 10 can easily recover its original state.

Next, the operation of the taping device will be described.

The storage tape 13 which is moved by the rotation of the tape feeding wheel 11 by the taping device 10.
The electronic components E are sequentially and sequentially stored in the respective storage recesses 13a via the suction nozzles 25 . Each storage recess 13a
Can be confirmed by the sensor 28 .

When the electronic component E is stored, the feed amount or the rotation amount of both the tape feeding wheel 11 and the tape feeding wheel 12 is detected by the reference detector and the shift detector, and the detection result is arithmetically processed by the control unit 20. And a matching comparison with a comparison reference value stored in a memory (not shown). If the comparison result is equal or within the set tolerance, the taping device 10 continues to operate (ie, does not push up the tape push-up pin 30). If the comparison result is mismatched and out of the set tolerance, the taping device 10 is operated. 10 is a tape push-up pin 3 with an alarm output
The stress release operation is performed by pushing up 0.

FIG. 4 is a flowchart showing the operation of the taping device shown in FIG. As shown in FIG. 4, first, it is determined whether or not a timing shift has occurred in the tape feeding (step S101). When the timing shift does not occur (No), the determination is repeated, and when the timing shift occurs (Yes), the tape push-up pin 30 is activated (Step S102), and thereafter, an apparatus alarm is output and the tape feed is stopped at the same time. (Step S10
3).

Next, it is determined whether or not the alarm is cleared (step S104). If the alarm is not cleared (No), the process returns to step S103. If the alarm is cleared (Yes), a return operation is started (step S105). After the return operation starts,
It is determined whether or not the tape feeding wheel 12 is located at a fixed point (step S106), and is not located at the fixed point (N
o), return to step S103, and if located at the fixed point (Yes), the storage recess 13 below the component insertion port 24
It is determined whether there is a work (electronic component E) in a (step S107). If there is a work (No), step S
Returning to 103, if there is no work (Yes), the push-up operation by the tape push-up pin 30 is stopped (OFF) (step S108).

Thereafter, the tape feeding wheel 11 is reversed by one pitch of the tape (step S109), and it is determined whether or not the tape feeding wheel 11 has stopped (step S110). Returning to S109, if the wheel 11 has stopped (Yes), the process ends.

Accordingly, when a compressive stress is applied to the storage tape 13 due to tape clogging or the like, the taping device 10 can release the load applied to the storage tape 13 by the stress release unit. It is possible to prevent the storage tape 13 from being damaged by a compressive stress generated as a result of direct application of the tape feeding force.

FIG. 5 shows a top cover section provided with a tape position sensor for detecting a tape feed amount.
(A) is a plan view and (b) is a cross-sectional view. As shown in FIG. 5, the transport direction a of the component insertion port 24 (see the arrow in the figure)
On the first top cover 22 located on the upstream side, a light transmission type tape position sensor 45 for detecting a moving state of the storage tape 13 is provided.

The tape position sensor 45 has two slit-shaped detection holes 46 provided in parallel with the first top cover 22.
(See (a)), the first top cover 22 facing one of the two light emitting portions 45a (see (b)) and the two detection holes 46 arranged below the storage tape 13.
Light receiving sections 45b arranged above the camera (see (b))
It is composed of The detection hole 46 is opened corresponding to the locus of the tape feed hole 19 provided in the storage tape 13 to be conveyed (see (a)).

The feed amount of the storage tape 13 can be directly detected by the tape position sensor 45 based on the light receiving state of the light transmitted through the detection hole 46 at the light receiving portion 45b.

FIG. 6 is a plan view showing an example of the arrangement of the detection holes in FIG. As shown in FIG. 6, the first top cover 22
Is formed by a plate provided with two detection holes 46. Both detection holes 46 are provided, for example, in the storage tape 13.
, Which are substantially perpendicular to the transport direction a (see the arrow in the figure) and are closely arranged side by side (see (a)) or spaced apart and parallel (see (b)). They are arranged side by side along the direction a (see (c)).

With these two detection holes 46, a slight movement of the tape feed hole 19 can be detected as a change in the amount of transmitted light. If the tape is clogged, the storage tape 13
Since the feed amount is almost zero or slight, the above-described arrangement example is used as an example, and the detection holes 46 having various arrangement patterns are used in accordance with the trouble situation of each storage tape 13.

FIG. 7 is an explanatory view showing another example of the stress release section using a solenoid. As shown in FIG. 7, the stress releasing portion is provided below the storage tape 13, and has a hemispherical tape push-up piece 47, a cylindrical push-up guide 48 whose upper end opening 48a is reduced in diameter, and a push-up guide 4
8 and a solenoid 49 located on the side of the lower end opening 48b. The tape push-up piece 47 is provided at the upper end of a cylindrical slide guide 50 slidably mounted in the push-up guide 48.
Accordingly, it is possible to prevent the tape push-up frame 47 from being inclined during sliding.

The slide guide 50 has an operating portion 49a of a solenoid 49 which enters the push-up guide 48 from the lower end opening 48b via a return spring 51 for avoiding overload.
It is connected to the tip of. The push-up guide 48 has an upper end opening 48 a adjacent to the lower surface of the storage tape 13.

When the solenoid 49 is actuated and the operating portion 49a advances, the slide guide 50 as well as the return spring 51 rises inside the push-up guide 48, and the tape push-up piece 47 projects from the upper end opening 48a. When the tape push-up piece 47 protruding from the upper end opening 48a is at its highest position, the storage tape 13 is pushed upward. The pushing up of the storage tape 13 is indicated by the push-up confirmation sensor 2.
9 is detected.

Therefore, by having the tape push-up piece 47 serving as an action point for pushing up the storage tape 13 at the tip of the solenoid 49, the push-up operation is performed only in one axial direction, and the action is performed in a short time by the solenoid 49 that operates at a high speed. be able to. The operation time corresponds to the response time of the solenoid 49. Further, the combination on one axis allows the stress release portion to be reduced in size, and the taping device 10 can be reduced in space.

In this case, since the taping device 10 can be reduced in size, the above-described tape push-up pin 30 can be used.
It is most suitable when tapping does not occur or when the taping device requires higher speed operation.

As described above, the taping device 10 according to the present invention detects the rotation amount of the delivery wheel 12 that performs a driven operation via the timing belt 15 with respect to the delivery amount or the drive amount of the storage tape 13 itself. The means and the means for detecting the rotation amount of the tape feeding wheel 11 directly connected to the tape feeding drive motor 17 are compared with the feeding amount or the rotation amount of both the feeding wheel 12 and the feeding wheel 11, and a shift occurs in both. Means for determining that the storage tape 13 is not damaged, means for forcibly releasing the stress in the direction opposite to the tape feeding direction so as not to damage the storage tape 13, and means for reversing the feeding wheel 11 by one pitch to recover the state. .

Thus, it is detected whether or not the operation of feeding the storage tape 13 by the feeding wheel 11 and the feeding of the storage tape 13 by the feeding wheel 12 are not displaced. By maintaining the state, the compressive stress applied to the storage tape 13 can be forcibly released in a direction in which the tape does not break.

Therefore, even if an excessive load is applied to the storage tape 13 during the tape feeding of the electronic component E, the storage tape 13
Is not damaged, the electronic component E stored in the damaged storage tape 13 is not discarded, and a re-taping operation with a lot of time and effort is not performed. Also, when a tape feeding abnormality occurs, after the compressive stress is released by the stress release section, the clogged storage tape 13 is removed by one.
The original state can be restored by returning the pitch, and even if a tape feeding error occurs, it is easy to recover to the normal state.

[0072]

As described above, according to the present invention,
The first and second wheels for transporting the storage tape
The deviation of the drive amount from the wheel is out of the preset allowable value.
That the abnormality detecting means, Runode stops the movement of the storage tape, electronic components of the tape feeding even accommodating tape excessive force on storage tape during occurs is not damaged. Moreover, if the deflection storage tape occurs, forced reverse rotation of the first wheel in the direction opposite to the direction out feed tape <br/>
By that, it is easy to return to a normal state even tape feeding abnormality occurs.
