Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounter tape cutter device, and more particularly, to a mounter tape cutter suitable for use in cutting a tape body of a component supply tape after the components are supplied to a component mounting device (mounter) and emptied. It relates to the improvement of the apparatus.

  The component supply tape is composed of a tape body provided with a component storage unit for storing components, and a cover tape covering the opening of the component storage unit for storing components, and the cover tape is peeled off by the component supply device. Supply parts to the mounting equipment.

  The tape body (hereinafter also referred to as “empty tape”) of the component supply tape after the components are supplied and emptied is discharged out of the component supply device. Conventionally, the discharged empty tape has a tape length. At the right time, the worker cut by hand with scissors and put it in the collection box at the right time.

  If this empty tape is not cut and collected, the empty tape may be caught by the component supply device, and smooth component supply may not be possible. In addition, empty tape may be scattered on the floor around the component mounting apparatus, which may hinder the operation of the component mounting apparatus, or may hinder the traffic of nearby workers.

  In order to solve this problem, Patent Document 1 proposes a tape cutter device 100 shown in FIG.

  The tape cutter device 100 includes a main body 102 that is detachably attached to the component supply device, a receiving body 104 that is provided at an upper portion of the main body 102 and has an insertion port 104A into which an empty tape T is fed, and a receiving body 104. Cutting means (not shown) provided on the main body 102 at the lower side for cutting the empty tape T into a predetermined size, and a storage body that is detachably provided on the main body 102 and accommodates the cut empty tape T 106.

  The storage body 106 is provided so as to be able to be taken in and out of the space portion 102B formed in a gate shape by the leg body 102A of the main body 102. In FIG. 3, the storage body 106 drawn by a virtual line (two-dot chain line) is The state pulled out from the space part 102B is shown.

  FIG. 4 shows the state of discharging the empty tape and the empty tape to the tape cutter device 100 when a large number of component supply tapes 110 are attached in parallel to the component supply device 108 and the components are supplied to the component mounting device 112. It is a perspective view which shows the injection | throwing-in condition. As the component mounting operation progresses, the component supply tape 110 attached in parallel is fed out, and a large number of empty tapes T after the components are taken out are discharged out of the component supply device 108 in parallel. A large number of the discharged empty tapes T enter the insertion openings 104A in the receiving body 104 of the tape cutter device 100 disposed on the lower side, and the empty tapes T are cut and stored by cutting means (not shown). It is accumulated in the body 106.

Japanese Patent Laid-Open No. 10-315187

  However, the tape cutter device 100 described in Patent Document 1 has the following problems.

(1) When the cutting means cuts the empty tape T, vibration and tensile force (tension) are generated in the empty tape T. Due to the influence of this vibration and tensile force (tension), the component suction position of the component supply device may be shifted, which causes a reduction in the rate of normal component suction.

(2) Also, a finger or the like may enter the insertion port 104A into which the empty tape T is fed, and there is a possibility of injury due to the cutting means.

  The present invention has been made in view of such a problem, and does not give an adverse effect associated with the cutting of the empty tape to the component supply device, can stabilize the component suction position, and is injured by the cutting means. An object of the present invention is to provide a tape cutter device with improved safety so as not to occur.

  In order to solve the above-mentioned problem, the present inventor provides a tape pressing means between the point where the empty tape is discharged from the component supply device and the cutting means in the tape cutter device, thereby cutting the empty tape. The vibration and tensile force generated at the time of cutting are absorbed by the tape pressing means and do not adversely affect the component suction position of the component supply device, and at the time of cutting the empty tape by the cutting means, the fingers are taped by the tape pressing device. I found out that I can prevent it from entering.

  On the other hand, when the empty tape discharged from the component supply device is pressed by the tape pressing means, the empty tape is pulled by this, and the component suction position may be adversely affected.

  In response to this, it has been found that by providing a tape tension relaxation means between the point where the empty tape is discharged from the component supply device and the tape pressing means, it is possible to prevent adverse effects on the component suction position.

  The present invention has been made based on such findings.

  That is, the tape cutter device according to the present invention is provided at the top of the internal space having a main body having an internal space in which the tape main body of the component supply tape after being supplied by the component supply device is charged and stored. In a tape cutter device of a mounter having a cutting means, a tape pressing means for pressing the tape main body discharged from the component supply device provided between the point where the tape main body is discharged from the component supply device and the cutting means And a tape tension relaxation means provided between the point where the tape main body is discharged from the component supply device and the tape pressing means, which relaxes the tension of the tape main body when the tape main body is pressed. It is characterized by that.

  According to the present invention, since the tape pressing means for pressing the empty tape discharged from the component supply device is provided, vibration and tensile force generated when the cutting means cuts the empty tape is absorbed by the tape pressing means. The transmission is hardly transmitted to the suction position of the component supply device, and even if the cutting means cuts the empty tape, there is no adverse effect on the suction position.

  Further, since the tape pressing means presses the empty tape, the empty tape can be stably cut.

  Furthermore, since the tape pressing means prevents fingers from entering the internal space of the main body when cutting the empty tape, the possibility of injury by the cutting means is low and the safety is excellent.

  Further, since means for reducing the tension of the empty tape is provided, even if the tape pressing means presses the empty tape and tension is generated in the empty tape, the suction position of the component supply device is not adversely affected.

  Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a side view showing main components of a tape cutter device 10 according to a first embodiment of the present invention.

  The tape cutter device 10 includes a main body 12, a cutting mechanism 14 (movable blades 14 a and 14 b), a storage body 16, a tape press 18, and a movable roller portion (tape tension relaxation means) 20.

  The main body 12 has a box shape having an internal space 12A and an opening 12B in the upper part, and a cutting mechanism 14 is provided in the upper part of the internal space 12A. A storage body 16 is provided below 14.

  Further, the main body 12 has a top plate 12D protruding from the upper end portion of the right side surface 12C to a point about one third of the internal space 12A of the main body 12 in the horizontal direction in the drawing, and upward from the upper end portion of the right side surface 12C. And a provided hood 12E.

  The cutting mechanism 14 includes two movable blades 14a and 14b facing each other, and these two movable blades 14a and 14b are slid in a direction approaching each other by an air cylinder (not shown) to cut an object. Yes. The two movable blades are on standby with an interval of about 70 mm during standby, and at the time of cutting, each of the movable blades slides by about 40 mm to cut the empty tape T that is the object. Then, after the empty tape T is cut, it returns to the original standby position.

  In addition, since a large number of component supply tapes are attached in parallel to the component supply device, a large number of empty tapes T are discharged from the component supply device in parallel. Therefore, the two movable blades 14a and 14b each have a predetermined length (for example, about 50 cm) so that a large number of empty tapes T arranged in parallel can be cut.

  The empty tape T cut by the cutting mechanism 14 is accumulated in the storage body 16. The storage body 16 is detachably provided in the internal space 12A of the main body 12. When the series of mounting operations by the component mounting apparatus is completed, the storage body 16 is taken out and the accumulated empty tape T is discarded. It is getting better.

  At the upper end of the left side surface 12F of the main body 12, a plate-like tape presser 18 is provided in the horizontal direction in the figure so as to face the top plate 12D. The tape presser 18 is disposed between the point P where the empty tape T is discharged from the component supply device and the cutting mechanism 14 and in the vicinity of the cutting mechanism 14. The tape presser 18 has a predetermined length (for example, about 50 cm) in the depth direction in the figure, similarly to the lengths of the two movable blades 14a and 14b of the cutting mechanism 14, and an air cylinder (not shown) The sliding movement is possible in a direction toward the top plate 12D and a direction away from the top plate 12D.

  The interval between the tape presser 18 and the top plate 12D is about 50 mm when the empty tape T enters the main body 12 without pressing the empty tape T. When pressing the empty tape T, the tape press 18 slides about 35 mm toward the top plate 12D and presses the empty tape T, so the distance between the tape press 18 and the top plate 12D is about 15 mm. When the operation is stopped (when the power is turned off), the tape press 18 is in contact with the top plate 12D so that fingers do not enter the main body 12.

  The tape retainer 18 has a role of preventing the component suction position from being adversely affected by vibrations and tensile forces generated in the blank tape T when the cutting mechanism 14 cuts the blank tape T. For this reason, a certain amount of frictional force can be obtained between the front end portion 18A of the tape press 18 and the empty tape T, and it is necessary for the front end portion 18A to be able to absorb vibration and tensile force generated in the empty tape T during cutting. From this point, it is preferable to use an elastic body such as rubber for the tip 18A of the tape presser 18, for example.

  The movable roller portion 20 includes a roller 20A, a support 20B, a fulcrum portion 20C, and a spring 20D. The roller 20A has a role of guiding the empty tape T that has been discharged from the discharge point P of the tape feeder 30 downward, and is rotatably supported by the support 20B. It is preferable that the roller 20A can be rotated with a small force so that the traveling direction can be smoothly changed downward without the empty tape being entangled with the roller 20A.

  The support 20B is supported by the fulcrum 20C, and a spring 20D is provided between the support 20B and the hood 12C. The support 20B has a predetermined angle (for example, 45) around the fulcrum 20C. It can only be rotated. The fulcrum part 20C is fixed to the hood 12E. Instead of providing the spring 20D between the support body 20B and the hood 12E, the fulcrum part 20C is made into a mechanism incorporating a spring so that the support body 20B rotates about a predetermined angle (for example, 45 °) around the fulcrum part 20C. You may be able to move.

  Next, the operation of the tape cutter device 10 will be described.

  In the tape feeder 30 to which the component supply tape is attached, before the suction position Q, the cover tape C is folded back by a separation plate (not shown), pulled upward and separated from the tape body T, and the component is sucked. At position Q, it is adsorbed by the head 32 and taken out.

  The tape body (empty tape) T after the parts are taken out is discharged from the discharge point P to the outside of the tape feeder 30. The discharged empty tape T changes its direction downward while being in contact with the roller 20A, passes through the opening 12B between the tape press 18 and the top plate 12D, and enters the main body 12 of the tape cutter device 10. Go.

  The tape presser 18 is slid toward the top plate 12D by an air cylinder (not shown) at a time interval (for example, every 10 seconds) required for the empty tape T to enter the main body 12 by a predetermined length (for example, 20 cm). Move and hold the empty tape T and pull it. Then, the roller 20A receives a force from the empty tape T in the lower left direction in the drawing, and the roller 20A rotates around the fulcrum portion 20C in the lower left direction as indicated by a two-dot chain line in the drawing.

  For this reason, even if the tape presser 18 holds and pulls the empty tape T, the empty tape T moves as indicated by a two-dot chain line in the figure. The tension of the empty tape T is relieved and no adverse effect on the suction position Q occurs.

  As the tape press 18 slides at a predetermined time interval (for example, every 10 seconds) and presses the empty tape T, the two movable blades 14a and 14b of the cutting mechanism 14 also slide toward each other. Cut the empty tape T. The empty tape T cut by the cutting mechanism 14 is accumulated in the storage body 16. After the cutting of the empty tape T by the cutting mechanism 14, the cutting mechanism 14 and the tape presser 18 return to their original positions even if they are slid.

  And after a series of operation is complete | finished, the storage body 16 is taken out from the main body 12, and what is necessary is just to discard the cut | disconnected empty tape T accumulated.

  Next, the effect of the tape cutter device 10 will be described.

  At the time of cutting the empty tape T, the tape presser 18 slides toward the top plate 12D, and the empty tape T is pressed and pulled as shown by a two-dot chain line in the figure. A certain amount of frictional force is generated between the two. For this reason, the vibration and tensile force generated when the cutting mechanism 14 cuts the empty tape T is absorbed by the tip 18A of the tape retainer 18 and hardly transmitted to the side closer to the suction position Q than the tip 18A. Even if the cutting mechanism 14 cuts the empty tape T, there is no adverse effect on the suction position Q.

  In addition, since the tape press 18 holds the empty tape T in the vicinity of cutting the empty tape T, the empty tape T can be stably cut.

  Further, when the empty tape T is cut, the tape presser 18 slides toward the top plate 12D, the interval between the tape presser 18 and the top plate 18D is narrowed, and a finger enters the internal space 12A of the main body 12. To prevent that. For this reason, the possibility of injury by the cutting mechanism 14 is low, and the tape cutter device 10 is highly safe. Further, if the tape press 18 slides toward the top plate 12D and the distance between the tape press 18 and the top plate 12D is not less than a predetermined distance, a mechanism that prevents the cutting mechanism 14 from sliding is provided. By providing it, even when a finger is sandwiched between the tape press 18 and the top plate 12D, an accident can be prevented and the safety of the tape cutter device 10 can be further enhanced. Further, when the operation of the tape cutter device 10 is stopped (when the power is turned off), the tape press 18 is in contact with the top plate 12D, and fingers are prevented from entering the main body 12. Yes. Also in this respect, the safety of the tape cutter device 10 is high. Furthermore, if both are movable blades as in the present embodiment, the cutting edge of the movable blade can be retracted from the top of the top plate 12D except during cutting, and fingers are less likely to touch the cutting edge.

  On the other hand, when the tape press 18 pulls the empty tape T, there is a concern that the empty tape T is tensioned and the suction position Q is adversely affected. However, when the tape presser 18 pulls the empty tape T, the roller 20A receives a force from the empty tape T in the lower left direction in the figure, and rotates around the fulcrum 20C in the lower left direction as indicated by a two-dot chain line in the figure. The empty tape T moves as indicated by a two-dot chain line in the figure. For this reason, the tension of the empty tape T between the tip 18A of the tape press 18 and the discharge point P is relaxed, and no adverse effect on the suction position Q occurs.

  In the first embodiment described above, the cutting mechanism 14 is a movable blade. However, as in the second embodiment shown in FIG. It is good also as the fixed blade 14c. By using one of the fixed blades 14c, one of the drive mechanisms can be omitted, which is advantageous in this respect.
