The housing 10 constitutes the outer surface of the tape cutting device 1. The housing 10 is, for example, a cover that covers the cutting unit 30. The cutting unit 30 (cutting blade 31 in FIG. 7) is provided inside the housing 10 so as not to come into contact with a part of the operator's body. The cutting unit 30 of the present embodiment is fixedly arranged with respect to the housing 10. The holding unit 50 is housed so as to be slidable with respect to the housing 10 (cutting unit 30). The holding unit 50 of the present embodiment is accommodated so as to be slidably movable in a predetermined linear direction (X direction) with respect to the housing 10.

In a state where the holding unit 50 is housed in the housing 10 (FIG. 2), a space 12 (FIG. 1) in which the tape 3 is arranged is formed between the housing 10 and the holding unit 50. The space 12 of this embodiment is formed by penetrating the tape cutting device 1 in the Y direction. Specifically, the space 12 is formed between the housing 10 and the holding unit 50 in a state of being housed in the housing 10.

FIG. 3 is a perspective view showing a state in which the holding unit 50 is open with respect to the housing 10. The holding unit 50 is configured to be slidable between a closed position P1 (FIG. 2) with respect to the housing 10 and an open position P2 (FIG. 3) with respect to the housing 10.

The first member 55 and the second member 56 are provided at both ends in the width direction (X direction) of the tape 3. A space for arranging the tape 3 is formed between the first member 55 and the second member 56. The first member 55 and the second member 56 regulate the movement of the tape 3 in the width direction. The first member 55 abuts on the tape 3 at one end in the width direction (end on the −X direction side) of the tape 3, and the second member 56 abuts on the other end in the width direction (end on the + X direction) of the tape 3. ), It comes into contact with the tape 3.

The first member 55 and the second member 56 are attached to the base 53 of the holding unit 50 and slide with the base 53. The base 53 is slidably connected along the holding unit moving mechanism 52. The base 53 is, for example, a plate-shaped member extending in the horizontal direction. An opening 57 through which the cutting blade 31 (FIG. 7) of the cutting unit 30 passes is formed in the central portion of the base 53. In the present embodiment, the first member 55 and the second member 56 are provided at both ends of the opening 57 in the Y direction.

As shown in FIG. 5, the first member 55 and the second member 56 of the present embodiment are provided so that the distance between them can be adjusted by the adjusting mechanism 58. The adjusting mechanism 58 of the present embodiment is an elastic member (for example, a spring or the like) in which the first member 55 and the second member 56 are urged in a direction approaching each other. The first member 55 is fixed to the base 53, and the second member 56 is attached to the base 53 so as to be movable relative to the first member 55. An adjusting mechanism 58 is provided in the second member 56, and the adjusting mechanism 58 moves the second member 56 in a direction approaching the first member 55. As a result, the distance between the first member 55 and the second member 56 is adjusted.

The first member 55 and the second member 56 have a first surface 59 and a second surface 60, respectively. The first surface 59 supports the lower surface S1 of the widthwise end of the tape 3. This restricts the downward movement of the tape 3 (in the −Z direction). The second surface 60 comes into contact with the side surface S2 of the tape 3. In the present embodiment, the tape 3 is sandwiched and held by the second surface 60 of the first member 55 and the second member 56. Specifically, the second surface 60 of the first member 55 abuts on one side surface S2 of the tape 3, and the second surface 60 of the second member 56 abuts on the other side surface S2 of the tape 3. Hold 3 As a result, the movement of the tape 3 in the width direction (X direction) is restricted.

As shown in FIGS. 5 and 6, at least one of the first member 55 and the second member 56 (the first member 55 in this embodiment) is provided with a pin-shaped member 61. The pin-shaped member 61 regulates the horizontal movement of the tape 3 in the Y direction (the direction in which the tape 3 extends). In the present embodiment, as shown in FIG. 6, the pin-shaped member 61 is inserted into a through hole (tape feed hole 7) penetrating in the thickness direction of the tape 3 to regulate the horizontal movement of the tape 3. .. A plurality of pin-shaped members 61 may be provided at intervals of the tape feed holes 7 in the direction in which the tape 3 extends. The pin-shaped member 61 is formed so as to extend upward from the first surface 59 that supports the tape 3.

At least one of the first member 55 and the second member 56 (both in the present embodiment) is provided with a claw portion 62 (regulatory member). The claw portion 62 restricts the movement of the tape 3 upward (+ Z direction). The claw portion 62 is provided so as to cover at least a part of the upper surface S3 of the widthwise end portion of the tape 3. Specifically, the end portion of the claw portion 62 is formed so as to extend toward the central portion side of the tape 3 from both end portions in the width direction of the tape 3 held by the first member 55 and the second member 56. For example, the claw portion 62 is a plate-shaped member extending in the horizontal direction above the first surface 59.

Here, an operation of an example of setting the tape 3 in the holding unit 50 will be described. The adjustment mechanism 58 widens the distance between the first member 55 and the second member 56 (for example, so as to be larger than the width of the tape 3), and inserts the tape feed hole 7 of the tape 3 into the pin-shaped member 61. At this time, one end in the width direction of the tape 3 (the end on the side where the tape feed hole 7 is provided) is arranged in the space between the first surface 59 of the first member 55 and the claw portion 62. Further, the other end of the tape 3 in the width direction is arranged in the space between the first surface 59 of the second member 56 and the claw portion 62, and the adjustment mechanism 58 keeps the distance between the first member 55 and the second member 56. It is narrowed so that the second surface 60 of the first member 55 and the second member 56 is brought into contact with the side surface of the tape 3.

The movement of the tape 3 in the Y direction is restricted by the pin-shaped member 61, the movement in the X direction is restricted by the second surface 60, the movement in the + Z direction is restricted by the claw portion 62, and the first surface 59 is restricted. Restricts movement in the -Z direction. In this way, the tape 3 is held by the holding unit 50.

Next, the cutting unit 30 will be described in detail.

FIG. 7 is a perspective view showing a schematic configuration of the cutting unit 30. 8 to 10 are side views showing a schematic configuration of the cutting unit 30.

As shown in FIGS. 7 to 10, the cutting unit 30 has a cutting blade 31 for cutting the tape 3 and a cutting blade receiving portion 32 provided on the cutting blade 31 so as to face each other in the vertical direction. The cutting blade receiving portion 32 is arranged so that the tape 3 is positioned between the cutting blade receiving portion 32 and the cutting blade 31 when the tape is cut. Specifically, the cutting blade receiving portion 32 is arranged above the cutting blade 31. The cutting blade 31 and the cutting blade receiving portion 32 are configured so that the relative position of the cutting blade 31 with respect to the cutting blade receiving portion 32 can be changed by the drive mechanism 40. In the present embodiment, the cutting blade receiving portion 32 is fixedly arranged with respect to the frame 44, and the relative position is changed by moving the cutting blade 31 in the vertical direction with respect to the cutting blade receiving portion 32. NS.

The cutting blade 31 of the present embodiment has a first cutting blade 31a (FIG. 8) and a second cutting blade 31b (FIG. 9). The first cutting blade 31a cuts the carrier tape 5. Specifically, the first cutting blade 31a cuts the carrier tape 5 in the width direction and divides the carrier tape 5 with the cover tape 6 left. The second cutting blade 31b cuts the carrier tape 5 and the cover tape 6 in the width direction. The second cutting blade 31b is arranged at a distance from the first cutting blade 31a in the extending direction (Y direction) of the tape 3. The first cutting blade 31a and the second cutting blade 31b are formed so as to extend in the width direction (X direction) intersecting the extending direction of the tape 3.

When the tape 3 is pulled out from the cutting unit 30 in the W1 direction of FIG. 14, which will be described later, a piece of the carrier tape 5 comes into contact with the first cutting blade 31 and is separated from the tape 3. In the present embodiment, the first cutting blade 31a removes a piece of the carrier tape 5 from the tape 3. As a result, only the cover tape 6 remains at the end of the tape 3.

The pulling out of the tape 3 from the cutting unit 30 (separation of the carrier tape 5 at the end of the tape 3) is performed with the holding unit 50 housed in the housing 10. Specifically, the tape 3 in the Y direction is pulled out through the space 12 (FIG. 1) formed between the housing 10 and the holding unit 50. At this time, the cutting blade 31 and the cutting blade receiving portion 32 are covered with the housing 10 so that a part of the worker's body does not come into contact with the cutting blade 31 and the cutting blade receiving portion 32.

The cutting blade 31 is fixed to the fixing member 33. The fixing member 33 is, for example, a plate-shaped member extending in the vertical direction. As shown in FIG. 10, the first cutting blade 31a is attached to the side surface of one side (−Y direction side) of the fixing member 33, and the second cutting blade 31b is attached to the other side (+ Y direction side) of the fixing member 33. Attached to the side. The second cutting blade 31b of the present embodiment is fixed to the fixing member 33 so that the upper end portion of the second cutting blade 31b is arranged at a position higher than the upper end portion of the first cutting blade 31a. As a result, when the drive mechanism 40 is driven, both the carrier tape 5 and the cover tape 6 can be cut by the second cutting blade 31b, and only the carrier tape 5 can be cut by the first cutting blade 31a. Further, the upper end portion (blade edge) of the second cutting blade 31b is formed so as to be inclined with respect to the thickness direction of the tape 3. As a result, the tape 3 can be cut more easily when the tape 3 is sandwiched between the second cutting blade 31b and the cutting blade receiving portion 32.

A first cutting blade receiving portion 32a and a fixed blade 32b are provided corresponding to the first cutting blade 31a and the second cutting blade 31b. The first cutting blade receiving portion 32a is arranged above the first cutting blade 31a and comes into contact with the upper surface of the tape 3 (cover tape 6) when the carrier tape 5 is cut. The fixed blade 32b is formed in a blade shape above the second cutting blade 31b.

11 to 13 are side views showing a schematic configuration of the cutting blade 31 and the cutting blade receiving portion 32. FIG. 14 is a side view showing a state in which the carrier tape 5 is removed from the tape 3. In addition, in FIGS. 11 to 14, some dimensions are exaggerated for convenience of explanation.

As shown in FIGS. 11 to 14, the cutting unit 30 has a posture changing member 37 that changes the posture of the carrier tape 5 removed by the first cutting blade 31a. The posture changing member 37 changes the direction in which the carrier tape 5 extends. Specifically, the posture changing member 37 changes the posture of the carrier tape 5 so that the extending direction of the carrier tape 5 is an inclined direction with respect to the XY plane. In the present embodiment, the posture changing member 37 changes its posture so that the extending direction of the carrier tape 5 is inclined upward with respect to the XY plane.

The posture changing member 37 is attached to the side surface of one of the fixing members 33 (the second cutting blade 31b side). The posture changing member 37 is, for example, a plate-shaped member extending in the vertical direction. The upper end portion of the posture changing member 37 is formed so as to extend in the width direction (X direction) of the tape 3. Thereby, the posture of the carrier tape 5 can be changed more easily.

Further, the upper end portion of the posture changing member 37 is arranged between the first cutting blade 31a and the second cutting blade 31b in the extending direction (Y direction) of the tape 3. In the present embodiment, the upper end portion of the posture changing member 37 is formed so as to extend toward the first cutting blade receiving portion 32a side. As a result, the posture changing member 37 can incline the extending direction of the piece of the carrier tape 5 more than the XY plane. By inclining the extending direction of the piece of the carrier tape 5 with respect to the XY plane, the direction in which the piece of the carrier tape 5 extends and the pulling direction W1 of the tape 3 can be made different. The tape 3 is pulled out in a state where the pull-out direction W1 of the tape 3 is inclined with respect to the adhesive surface between the carrier tape 5 and the cover tape 6. As a result, the carrier tape 5 can be more easily removed from the tape 3 by the first cutting blade 31a.

As shown in FIG. 13, the attitude changing member 37 pulls out the tape 3 from the cutting unit 30 in the pulling direction W1 (FIG. 14) in a state where the carrier tape 5 extends in an inclined direction with respect to the XY plane. The tape 5 comes into contact with the first cutting blade 31a. As a result, as shown in FIG. 14, the carrier tape 5 is removed from the tape 3. The pull-out direction W1 of the tape 3 of the present embodiment is a direction inclined upward with respect to the XY plane. By inclining the pull-out direction W1 of the tape 3, the tape feed hole 7 is disengaged from the pin-shaped member 61. After that, the carrier tape 5 can be more easily removed from the tape 3 by pulling out the tape 3 in the pulling direction W1 in a state where the carrier tape 5 is in contact with the first cutting blade 31a.

Next, the configuration of the drive mechanism 40 will be described in detail.

The drive mechanism 40 sets the relative positions of the cutting blade 31 with respect to the cutting blade receiving portion 32 to the first relative position R1 (FIG. 10), the second relative position R2 (FIG. 12), and the third relative position R3 (FIG. 10). Change to 13). The first relative position R1 is a relative position (relative position before driving of the drive cylinder 41 described later) when the tape 3 to be cut is arranged between the cutting blade 31 and the cutting blade receiving portion 32. Specifically, the first relative position R1 is a position where the cutting blade 31 is retracted from the cutting blade receiving portion 32. The second relative position R2 is a relative position when the carrier tape 5 is cut by the first cutting blade 31a. The third relative position R3 is a relative position where the first cutting blade 31a is farther from the first cutting blade receiving portion 32a than the second relative position R2. Specifically, at the third relative position R3, the distance D3 (FIG. 13) between the first cutting blade 31a and the first cutting blade receiving portion 32a is the distance D2 (FIG. 12) at the second relative position R2. ), And smaller than the distance D1 (FIG. 10) at the first relative position R1.

The drive mechanism 40 of the present embodiment includes a drive cylinder 41 (FIG. 1) driven by a fluid, a slider 42 (FIG. 7) connected to the drive cylinder 41, and a guide shaft 43 (FIG. 7) that guides the movement of the slider 42. 7) and.

The drive cylinder 41 is, for example, a double-acting cylinder. Specifically, the drive cylinder 41 moves the slider 42 in the first direction by supplying the fluid in the first direction (for example, upward), and the second direction opposite to the first direction. The fluid is supplied downward (for example) to move the slider 42 in the second direction. When the fluid is supplied to the drive cylinder 41 in the first direction, the relative position of the cutting blade 31 with respect to the cutting blade receiving portion 32 is changed from the first relative position R1 (FIG. 10) via the slider 42. It is changed to the relative position R2 (FIG. 12) of 2. When the fluid is supplied to the drive cylinder 41 in the second direction, the relative position is changed from the second relative position R2 (FIG. 12) or the third relative position R3 (FIG. 13) via the slider 42. It is changed to the first relative position R1 (FIG. 10).

In the present embodiment, an open / close detection unit 70 (FIG. 2) for detecting the position (open / close state) of the holding unit 50 in the housing 10 is provided. When the open / close detection unit 70 detects that the holding unit 50 has moved from the closed position to the open position, the drive mechanism 40 sets the relative position of the cutting blade 31 with respect to the cutting blade receiving unit 32 to the second relative position R2. It is configured to regulate the change to. Specifically, the detection of the open / close detection unit 70 cuts off the supply of the fluid in the first direction in the drive cylinder 41 of the drive mechanism 40, and regulates the cutting blade 31 from moving upward. At this time, the fluid may be supplied to the drive cylinder 41 in the second direction so that the cutting blade 31 moves downward. As a result, when the holding unit 50 is located in the open position, it is possible to prevent the cutting blade 31 from moving upward due to a malfunction.

The open / close detection unit 70 (for example, a sensor or the like) of the present embodiment is located at a position where the holding unit 50 is housed in the housing 10 (closed position) or pulled out from the housing 10 (open position). Detects where it is located. For example, the open / close detection unit 70 detects the open / closed state of the holding unit 50 by contacting the holding unit 50 in the closed state and separating from the holding unit 50 in the open state. Specifically, the dog 54 (FIG. 2) formed at the rear end portion (-X direction end portion) of the base 53 abuts on the open / close detection unit 70 when it is in the closed state, and the open / close detection is performed when it is in the open state. By separating from the unit 70, the open / closed state of the holding unit 50 is detected.

In the present embodiment, the control unit (not shown) controls the drive of the drive mechanism 40 based on the information detected by the open / close detection unit 70. The control unit includes, for example, a memory, a processing circuit corresponding to a processor such as a CPU that executes a program, and a storage device (storage unit).

The slider 42 is moved by driving the drive cylinder 41 to change the relative position of the cutting blade 31 with respect to the cutting blade receiving portion 32. The slider 42 is connected to the piston rod 41a of the drive cylinder 41. The slider 42 moves by driving the drive cylinder 41 by engaging with the piston rod 41a in the vertical direction. The slider 42 is attached to a fixing member 33 that fixes the cutting blade 31.

The guide shaft 43 is connected to the slider 42 in a state where the slider 42 can slide and move. The guide shaft 43 of the present embodiment guides the vertical movement of the slider 42. The guide shaft 43 is, for example, a rod-shaped member extending in the vertical direction. The guide shaft 43 is inserted into the through hole 42a (FIG. 7) penetrating in the vertical direction in the slider 42. A plurality of guide shafts 43 (for example, two) are provided at both ends of the fixing member 33 in the X direction. The guide shaft 43 is fixed to, for example, the frame 44.

15 and 16 are side views showing a schematic configuration of the guide shaft 43 and the plunger 45. In addition, in FIG. 15 and FIG. 16, for convenience of explanation, some members (plunger main body and the like) of the plunger 45 are omitted.

A recess 43a recessed in either the slider 42 or the guide shaft 43 is formed in a direction intersecting the moving direction of the slider 42. As shown in FIGS. 15 and 16, the recess 43a of the present embodiment is formed in the guide shaft 43. The recess 43a is formed by being recessed toward the axial center of the guide shaft 43. For example, the recess 43a is formed in a groove shape on the entire circumference at a position between one end and the other end of the guide shaft 43. This makes it possible to easily align the recess 43a with the plunger 45 described later.

An inclined surface S4 inclined with respect to the axial direction (Z direction) is formed in the recess 43a. The inclined surface S4 is formed in a curved surface, for example. In the present embodiment, the recess 43a (inclined surface S4) is formed symmetrically vertically with respect to a direction orthogonal to the axial direction.

A plunger 45 is provided on either the slider 42 or the guide shaft 43. In this embodiment, the plunger 45 is provided on the slider 42 (FIG. 10). The plunger 45 slides in the axial direction together with the slider 42. The plunger 45 has a movable portion 45a that is urged toward the recess 43a side. The movable portion 45a is urged by an elastic member 45b (for example, a spring or the like). An inclined surface S5 inclined with respect to the axial direction is formed on the movable portion 45a. The inclined surface S5 is formed, for example, in a curved surface. In the present embodiment, the movable portion 45a (inclined surface S5) is formed symmetrically vertically with respect to a direction orthogonal to the axial direction. For example, the plunger 45 is a ball plunger, and the movable portion 45a is a ball of the ball plunger.

With such a configuration of the drive mechanism 40, when the drive cylinder 41 is driven, the piston rod 41a moves, and the first cutting blade 31a moves upward from the state (R1) shown in FIG. 10 through the slider 42 and the fixing member 33. It moves and is arranged at the position (R2) shown in FIG.

In the present embodiment, as shown in FIG. 9, the upper end portion of the posture changing member 37 is arranged at a position higher than the upper end portion of the second cutting blade 31b. Therefore, when the fixing member 33 (FIG. 10) moves upward, the posture changing member 37 first comes into contact with the tape 3 (see FIG. 11). At this time, the tape 3 is in a state of being pressed against the fixed blade 32b by the posture changing member 37. When the fixing member 33 moves further upward from this state, the tape 3 is cut by the second cutting blade 31b and the fixing blade 32b, and the state of the second relative position R2 shown in FIG. 12 is obtained. By lifting the tape 3 by the posture changing member 37, the tape 3 can be pressed against the fixed blade 32b, so that the tape 3 can be cut more easily.

At this time, the carrier tape 5 is cut and divided by the first cutting blade 31a. In the present embodiment, the first cutting blade 31a is in a state of being inserted into the cover tape 6 by a small distance. That is, the distance D2 between the first cutting blade 31a and the first cutting blade receiving portion 32a is smaller than the thickness of the cover tape 6.

When the first cutting blade 31a is located at the second relative position R2 (FIG. 12), the plunger 45 is in the state shown in FIG. Specifically, the movable portion 45a of the plunger 45 is arranged at a position eccentric from the axially central portion 43aa of the recess 43a. In the present embodiment, the movable portion 45a is arranged at a position eccentric upward from the axially central portion 43aa of the recess 43a. More specifically, the central height C3 of the movable portion 45a is higher than the height C1 of the axial central portion 43aa of the concave portion 43a, and the axial end portion 43ab of the concave portion 43a (the upper end portion in the present embodiment). It is lower than the height C2.

Here, the axial central portion 43aa is a portion located at the center of the concave portion 43a in the axial direction (Z direction). In the present embodiment, the axially central portion 43aa of the recess 43a is a portion located on the axis of symmetry of the recess 43a. When the recess 43a is not formed symmetrically in the vertical direction, the axial central portion 43a of the recess 43a is the height of the movable portion 45a in the engaged state in which the movable portion 45a and the recess 43a are engaged in the vertical direction (Z direction). It is the part located in the direction.

When the supply of fluid to the drive cylinder 41 is cut off from the position shown in FIG. 12 (second relative position R2), the first cutting blade 31a moves to the third relative position R3 shown in FIG. In the present embodiment, the movement from the second relative position R2 to the third relative position R3 is performed by the plunger 45. Specifically, as the movable portion 45a moves from the state shown in FIG. 15 to the state shown in FIG. 16 in the axial direction (downward), the slider 42 provided with the plunger 45 also moves in the axial direction (downward). Moving.

As shown in FIG. 15, the movable portion 45a is urged in the + X direction by the elastic member 45b in a state where the central height C3 of the movable portion 45a is lower than the height C2 of the axial end portion 43ab. The movable portion 45a moves toward the axially central portion 43aa of the recess 43a. By the urging force of the inclined surfaces S4 and S5 and the elastic member 45b, a force having a component for urging the plunger 45 in the vertical direction (downward in the present embodiment) is applied, so that the movable portion 45a is recessed. It moves to the axial central portion 43aa side of 43a. In the present embodiment, the driving force of the driving cylinder 41 is larger than the downward force generated in the plunger 45, and the movable portion 45a moves upward beyond the recess 43a, so that the first relative position R1 Moves from to the second relative position R2. When the drive of the drive cylinder 41 is stopped, the movable portion 45a moves downward due to the downward force on the movable portion 45a generated by the urging force of the inclined surfaces S4 and S5 and the elastic member 45b, and the second It moves from the relative position R2 to the third relative position R3.

At the third relative position R3, as shown in FIG. 16, the movable portion 45a is arranged so that the center height C3 of the movable portion 45a and the height C1 of the axial central portion 43aa of the recess 43a are the same. NS. Since the slider 42 provided with the plunger 45 moves downward with respect to the guide shaft 43, the first cutting blade 31a connected to the slider 42 through the fixing member 33 also moves downward. As a result, the first cutting blade 31a moves from the second relative position R2 to the third relative position R3.

The difference (D4 shown in FIG. 15) between the height C3 of the movable portion 45a of the plunger 45 at the second relative position R2 and the height C1 of the movable portion 45a at the third relative position R3 is the first cutting blade 31a. It is the moving distance of. The moving distance of the first cutting blade 31a can be adjusted by changing D4, for example. At the third relative position R3 (FIG. 13), the size D3 of the gap formed between the first cutting blade 31a and the first cutting blade receiving portion 32a is, for example, equal to or larger than the thickness of the cover tape 6. , It is less than or equal to the thickness of the entire tape 3.

In the present embodiment, a relative position detecting unit 46 (for example, a sensor or the like) for detecting the relative position of the cutting blade 31 with respect to the cutting blade receiving unit 32 is provided. When the relative position detecting unit 46 detects that the relative position of the drive cylinder 41 of the drive mechanism 40 has been changed from the first relative position R1 to the second relative position R2, the supply of the fluid is cut off. It is composed. That is, the relative position detecting unit 46 (FIG. 9) detects the position of the cutting blade 31 to shut off the supply of the fluid from the state of FIG. The control unit controls the drive of the drive mechanism 40 based on the information detected by the relative position detection unit 46.

For example, the relative position detecting unit 46 detects the position of the cutting blade 31 depending on whether or not it is in contact with the dog 47 attached to the slider 42 that moves up and down. Specifically, at the first relative position R1 shown in FIG. 10, the dog 47 (FIG. 9) was at a position separated from the relative position detecting unit 46 and moved to the second relative position R2 shown in FIG. At that time, the dog 47 comes into contact with the relative position detection unit 46. When the dog 47 comes into contact with the relative position detection unit 46, the relative position detection unit 46 detects that the first cutting blade 31a is located at the second relative position R2, so that the drive cylinder 41 is reached. Fluid supply is cut off. As a result, the relative position can be changed from the second relative position R2 to the third relative position R3 (FIG. 13) by the plunger 45 immediately after the carrier tape 5 is cut, so that immediately after the carrier tape 5 is cut. The tape 3 can be pulled out from the cutting unit 30.

Next, the configuration of the removing member 65 for removing the carrier tape 5 separated from the tape 3 by the first cutting blade 31a from the space on the side of the first cutting blade 31a will be described.

FIG. 17 is a perspective view showing an operation in which the carrier tape 5 is removed by the removing member 65. As shown in FIGS. 14 and 17, the carrier tape 5 (cut piece) removed from the tape 3 by the first cutting blade 31a is located, for example, around the first cutting blade 31a. In the present embodiment, a removing member 65 (FIG. 17) for removing the carrier tape 5 from the space (passage 35) on the side of the first cutting blade 31a is provided. The carrier tape 5 before being removed by the removing member 65 is located in the passage 35. The passage 35 is formed, for example, surrounded by the first cutting blade 31a, the second cutting blade 31b, and the upper surface S6 of the fixing member 33.

The passage 35 is formed so as to extend along the first cutting blade 31a on one side (side of the + Y direction side) of the first cutting blade 31a. In the passage 35, the carrier tape 5 removed by the removing member 65 passes through. On the other side (side in the −Y direction) of the first cutting blade 31a, an accommodating portion 80 (FIG. 17) for accommodating the removed carrier tape 5 is provided. In addition, a first guide 81 is provided to guide the carrier tape 5 removed through the passage 35 from the passage 35 to the accommodating portion 80. For example, the first guide 81 has an inclined surface 81a extending in the direction of the accommodating portion 80 below the front end portion (+ X direction end portion) of the passage 35.

In the present embodiment, the second guide 82 is further provided on the other side (side in the −Y direction) of the first cutting blade 31a. The second guide 82 is formed so as to guide the carrier tape 5 from the first cutting blade 31a to the accommodating portion 80. As a result, even when the carrier tape 5 removed from the tape 3 falls on the side opposite to the passage 35 side of the first cutting blade 31a, the carrier tape 5 can be accommodated in the accommodating portion 80.

As shown in FIG. 4, the removing member 65 of the present embodiment is provided in the holding unit 50. Specifically, the removing member 65 is formed so as to extend downward from the base 53 of the holding unit 50. The removing member 65 is, for example, a plate-shaped (columnar) member extending in the vertical direction. The base 53 is provided behind the position where the tape 3 is held by the holding unit 50 (in the −X direction).

The removing member 65 moves in the width direction in the space lateral to the first cutting blade 31a to remove the carrier tape 5 separated from the tape 3 by the first cutting blade 31a. Specifically, the removing member 65 moves and comes into contact with the carrier tape 5 located in the passage 35, so that the carrier tape 5 is pushed out of the passage 35. The carrier tape 5 extruded to the outside of the passage 35 is accommodated in the accommodating portion 80 via the first guide 81.

The removing member 65 is configured to be movable in the width direction (X direction) of the tape 3 by the removing member moving mechanism. In the present embodiment, the removal member moving mechanism that moves the removing member 65 is the holding unit moving mechanism 52 (FIG. 2) that moves the holding unit 50 in the width direction. That is, when the holding unit 50 slides in the width direction with respect to the housing 10, the removing member 65 also slides in the width direction together with the holding unit 50. As a result, when the holding unit 50 is pulled out from the housing 10 after the work of removing the carrier tape 5 from the tape 3 is completed, the removal member 65 removes the carrier tape 5 from the space on the side of the first cutting blade 31a. Can be removed from.

The pulling direction of the tape 3 may be, for example, a direction inclined downward with respect to the XY plane, a direction along the XY plane, or the like.

Further, although the drive mechanism 40 has a drive cylinder 41 driven by a fluid, the drive mechanism 40 may drive the cutting unit 30 with a configuration other than the drive cylinder 41. The drive mechanism 40 may be, for example, a mechanism using a motor or the like. As a result, the position of the first cutting blade 31a can be finely adjusted.

Further, the tape cutting device 1 may include a tape pulling mechanism for pulling out the tape 3 from the cutting unit 30.

Further, the holding unit moving mechanism 52 is not limited to the holding unit moving mechanism 52, although the holding unit 50 is slidably moved by the holding unit moving mechanism 52. For example, the holding unit moving mechanism 52 may be a mechanism that has a power source and automatically opens and closes the holding unit 50. Further, although the holding unit moving mechanism 52 has a guide rail that supports the holding unit 50 so as to be slidable (in the X direction), the holding unit 50 may be moved by a mechanism other than the guide rail.

Further, the removal member moving mechanism for moving the removing member 65 is a holding unit moving mechanism (rail mechanism) 52 for moving the holding unit 50 in the width direction, but the present invention is not limited to this. The removing member moving mechanism is another mechanism as long as it moves in the width direction in the space lateral to the first cutting blade 31a and removes the carrier tape 5 separated from the tape 3 by the first cutting blade 31a. It may be. For example, the removing member moving mechanism and the holding unit moving mechanism 52 may be independent moving mechanisms.

Further, the first member 55 and the second member 56 are provided so that their distances from each other can be adjusted by the adjusting mechanism 58, but the present invention is not limited to this as long as the holding unit 50 can hold the tape 3. For example, when the width of the tape 3 to be cut is one kind, the first member 55 and the second member 56 may be integrally formed as one member.

Further, the first member 55 is fixed to the base 53, and the second member 56 is attached to the base 53 so as to be relatively movable with respect to the first member 55, but the present invention is not limited to this. For example, the second member 56 may be fixed to the base 53, and the first member 55 may be attached to the base 53 so as to be relatively movable with respect to the second member 56. Further, both the first member 55 and the second member 56 may be attached to the base 53 so as to be relatively movable.

Further, the cutting blade receiving portion 32 is fixedly arranged with respect to the frame 44, and the relative position is changed by moving the cutting blade 31 in the vertical direction with respect to the cutting blade receiving portion 32. , Not limited to this. For example, the cutting blade 31 may be fixedly arranged with respect to the frame 44, and the cutting blade receiving portion 32 may move with respect to the cutting blade 31. Further, both the cutting blade 31 and the cutting blade receiving portion 32 may be configured to move with respect to the frame 44.
