  The present invention relates to a component supply device including a splicing detection device that detects a connection portion between two carrier tapes holding a plurality of components.

  2. Description of the Related Art Conventionally, in a component supply apparatus equipped in a component mounting apparatus, a carrier tape holding a plurality of components at regular intervals is wound around a supply reel, and a sprocket that engages a feed hole formed in the carrier tape is driven. Accordingly, the carrier tape wound around the supply reel is fed at a predetermined pitch to supply the component to the component supply position, and the component is conveyed to the component mounting apparatus by the component adsorption device.

  In this type of component supply device, when the remaining amount of the components held on one supply reel decreases, the starting end portion of the carrier tape wound around another supply reel holding the same type of components is used. So-called splicing, which is connected to the terminal portion of the carrier tape whose remaining amount is low, is performed. By this splicing, parts can be supplied continuously, so that it is not necessary to stop the operation of the component mounting apparatus for replenishing the parts, and the operating rate of the component mounting apparatus can be improved.

  By the way, in splicing, based on the identification code given to the supply reel, the carrier tape holding the parts different from the parts held on the carrier tape whose remaining amount is reduced should not be connected. However, since there is a possibility that an incorrect carrier tape is connected due to an operator's operation error or the like, it is necessary to be able to recognize from which point an incorrect component is mounted. For this reason, in this type of component supply device, a splicing detection device for detecting a connection portion (splicing portion) between two carrier tapes is provided.

A component supply apparatus including such a splicing detection apparatus is described in Patent Document 1, for example. In the device described in Patent Document 1, each carrier tape of two taping electrical components (62) is connected by a metal connection piece (100), and the metal piece is provided in a moving path of the taping electrical component. The connection part (103) of the taping electrical component is detected by detecting with a metal detector comprising a pair of electrodes (166) and the like.

The two engaging recesses 27a and 27b do not necessarily have the same shape, and may have different shapes.

  As shown in FIGS. 2 and 3, the splicing detection device 30 includes a support block 31 attached to the main body 11, and an engagement member 33 rotatably supported on a support shaft 32 attached to the support block 31. The detection sensor 34 that detects the rotation of the engagement member 33 is mainly configured.

  The support shaft 32 is attached in parallel to the longitudinal direction of the carrier tape 14, and a through hole 33 a formed at the center of the engagement member 33 is fitted to the support shaft 32. A flat plate-like engagement lever portion 35 having a width slightly larger than the arrangement pitch of the feed holes 17 is formed on one end side of the engagement member 33 around the through hole 33a. A detection lever portion 36 is formed on the other end side.

  The engaging lever portion 35 can be brought into contact (engaged) with the end surface 14 a of the carrier tape 14 by the rotation of the engaging member 33, and is inserted between the support block 31 and the detection lever portion 36. The urging force of the spring 37 is always in contact with the end surface 14 a of the carrier tape 14. The flat plate-like engagement lever portion 35 is penetrated by a substantially rectangular opening 38, and the opening 38 is formed at both ends of the opening 38, that is, in the longitudinal direction of the carrier tape 14 of the engagement lever portion 35. The two engaging portions 35a and 35b are formed at the two locations spaced apart by a predetermined amount in the longitudinal direction of the carrier tape 14. As shown in FIG. 4, the two engaging portions 35a and 35b are formed in a shape that matches the two engaging concave portions 27a and 27b formed in the first carrier tape 14A.

  The detection lever portion 36 is disposed so as to cross the slit 40 a of the detection block 40 of the detection sensor 34. As an example, the detection sensor 34 includes a light source that irradiates light so as to cross the slit 40a of the detection block 40, and an optical sensor that detects light from the light source, and the light from the light source is blocked. , A transmission sensor that emits a detection signal. Accordingly, when the engagement member 33 is rotated to an angular position where the two engagement portions 35a and 35b engage with the two engagement recesses 27a and 27b formed on the first carrier tape 14A, the detection is performed. Light from the light source is blocked by the detection lever portion 36 located in the slit 40a of the block 40, and the engagement between the engagement portions 35a and 35b and the engagement recess portions 27a and 27b can be detected.

  The detection sensor 34 is not limited to the above-described transmission type sensor, but may be a reflection type sensor that detects reflected light from the surface of the detection lever unit 36, a proximity sensor that is sensitive to the detection lever unit 36, or the like. Other sensors can also be used.

  As shown in FIG. 3, the support block 31 of the splicing detection device 30 is provided with a support body 41 that supports the lower surface of the carrier tape 14 that is transported on the transport path 23. A recess 41a for accommodating the storage portion 15 is formed. Further, a cover 42 is attached to the support block 31 so as to cover the upper surface of the support body 41, and the carrier tape 14 can pass between the upper guide portion 42a of the cover 42 and the support body 41. Yes. A leaf spring 43 is inserted between the upper surface of the carrier tape 14 and the upper guide portion 42 a of the cover 42, and the spring force of the leaf spring 43 presses the carrier tape 14 to a position where it abuts on the upper surface of the support body 41. Then, the carrier tape 14 passing through the splicing detection device 30 is positioned.

  Next, the operation in the present embodiment will be described. When the components 13 are mounted on the substrate, the carrier tape 14 is fed by one pitch by driving the sprocket 22 by a motor (not shown), and the components 13 are supplied to the component supply position 18 one by one. At this time, the cover tape 16 affixed to the carrier tape 14 is peeled off before the component supply position 18, guided by the roller 24, and discharged to a predetermined position. When the component 13 is supplied to the component supply position 18, the component 13 is sucked by a suction nozzle of a component transfer device (not shown), transferred to a mounting position in the component mounting device, and mounted on a substrate by the component mounting device. The

  Each time such a component mounting operation is performed, the remaining amount of the component of the identification code corresponding to the component 13 is sequentially subtracted by a control device (not shown). When the remaining number of the parts 13 held on the first carrier tape 14A wound around the supply reel 12 becomes a predetermined number or less, a parts replenishment command is output from the control device, and the worker performs the replenishment work of the parts 13 (Splicing work) is executed.

  In this case, the control device retrieves the identification code of the supply reel 12 in which the remaining number of the parts 13 is equal to or less than the predetermined number from the correspondence table and displays it on the display device as a replacement reel. The required reel type can be identified by referring to the identification code.

  By the way, the replenishment work of the parts 13 is performed by removing the supply reel 12 wound with the first carrier tape 14A in which the remaining number of the parts 13 is equal to or less than a predetermined value from the main body 11 of the parts supply apparatus 10, and then removing the parts 13 This is done by setting another supply reel, in which the held second carrier tape 14 </ b> B is fully wound, to the main body 11. Then, the second carrier tape 14B is pulled out from the supply reel, and the end portion 14A1 of the first carrier tape 14A and the start end portion 14B1 of the second carrier tape 14B are connected by the connecting member 25 as shown in FIG. To do. The end portion 14A1 of the first carrier tape 14A and the start end portion 14B1 of the second carrier tape 14B are connected to each other via a connecting member 25 using a tape connecting tool (not shown) at the feed hole. As such a tape connecting tool, for example, the one described in JP-A-11-40984 can be used.

  The first and second carrier tapes 14A and 14B connected by the connecting member 25 are sent out from the second supply reel 12 by the drive of the sprocket 22, and the end portion 14A1 of the first carrier tape 14A is splicing detection device. The two engagement portions 35a and 35b of the engagement member 33 are respectively inserted into the two engagement recesses 27a and 27b of the notch portion 27 formed on the end surface 14a of the first carrier tape 14A when passing through 30. When engaged (see the two-dot chain line in FIGS. 5 and 6), the engaging member 33 is rotated about the support shaft 32 by the biasing force of the spring 37. As a result, as shown in FIG. 7, the detection lever portion 36 is positioned and held at a position where the light from the light source of the detection sensor (transmission sensor) 34 is blocked, and a detection signal is emitted from the detection sensor (transmission sensor) 34. It is done. In this manner, it can be detected that the cutout portion 27 formed in the first carrier tape 14A has passed through the splicing detection device 30.

  At this time, since the carrier tape 14 passing through the splicing detection device 30 is positioned at a position where it abuts on the upper surface of the support body 41 by the spring force of the leaf spring 43, the engagement portions 35a and 35b of the engagement member 33 and The engagement of the notch 27 with the engagement recesses 27a and 27b can be performed accurately.

  When the sprocket 22 is driven from the state where the two engaging portions 35a and 35b of the engaging member 33 are engaged with the two engaging concave portions 27a and 27b formed on the first carrier tape 14A. Due to the action of the second surfaces (inclined surfaces) 27a2 of the engaging recesses 27a and 27b, the engaging member 33 is smoothly rotated and returned against the urging force of the spring 37, and again the end surface of the first carrier tape 14A. 14a comes into contact.

  In this case, the distance L0 from the notch 27 to the end of the end portion 14A1 of the first carrier tape 14A is known in advance, and the distance from the splicing detection device 30 to the component supply position 18 is also known. In the control device, it is possible to recognize when the first component 13 held on the second carrier tape 14B is supplied to the component supply position 18.

  In this way, the connection positions of the first and second carrier tapes 14A and 14B connected to each other can be recognized, whereby the parts 13 held on the second carrier tape 14B at a predetermined timing can be recognized. Residual amount management can be started, and even if an operator connects the wrong carrier tape, it is easy to know from which timing the wrong component was mounted on the board, Recovery can be performed appropriately and efficiently.

  According to the above-described embodiment, the notch 27 and the engagement member 33 constituting the splicing detection device 30 include the two engagement recesses 27a and 27b and the engagement portions 35a and 35b, respectively. As shown in FIG. 9 (A), the end portions of the connecting portions of the first and second carrier tapes 14A and 14B are rolled up to form a gap between the connected carrier tapes 14A and 14B. Even if CL occurs, even if either one of the engaging portions 35a or 35b corresponds to the gap CL, the other engaging portion 35b or 35a is engaged with the end surface 14a of the first carrier tape 14A. As a result of the contact, the engaging member 33 is not rotated, and the detection sensor 34 does not react erroneously or cause malfunction of the carrier tape.

  Moreover, since the two engaging recesses 27a and 27b are formed between the plurality of feed holes 17, the width of the carrier tape 14 is increased even if the two engaging recesses 27a and 27b are formed. In addition, since the engaging portions 35a and 35b are formed at both ends of the opening 38 by providing the opening 38 in the engaging lever portion 35, the two engaging portions 35a and 35b are very easy. Can be formed.

  However, the two engaging portions 35a and 35b are not limited to the configuration described in the above-described embodiment. For example, the two protruding portions are spaced apart in the longitudinal direction of the carrier tape 14 on a flat plate. It is good also as an engaging part.

  FIG. 8 shows another form of the carrier tape. The carrier tape 114 shown in FIG. 8A is a component 113 having a smaller width and length than the carrier tape 14 described in the previous embodiment. The notch 127 formed of the two engaging recesses 127a and 127b is formed at a position separated by a preset distance L1 from the end of the end portion 114A1 of the carrier tape 114, and the component 113. The pitch P2 of the storage holding portion 115 that stores and holds is set to ½ of the pitch P1 of the feed holes 117. As a result, the component 113 can be supplied to the component supply position by driving the sprocket engaged with the feed hole 117 by a half pitch. In the figure, reference numeral 25 denotes a connecting member for connecting two carrier tapes 114.

  On the other hand, the carrier tape 214 shown in FIG. 8B accommodates and holds a part 213 having a larger width and length than the carrier tape 14 described in the previous embodiment, and has two engagement recesses 227a. The notch portion 227 made of 127b is formed at a position separated by a preset distance L2 from the end of the end portion 214A1 of the carrier tape 214, and the pitch P3 of the storage holding portion 215 for storing and holding the component 213 is: It is set to twice the pitch P1 of the feed holes 217. As a result, the component 213 can be supplied to the component supply position by driving two pitches of the sprocket engaged with the feed hole 217.

  In the above-described embodiment, the two engaging portions 35 a and 35 b of the engaging member 33 that engages the notch portion 27 formed by the two engaging concave portions 27 a and 27 b formed on the carrier tape 14 are formed on the carrier tape 14. However, it is not necessary to engage at two points in a strict sense, and the projecting amounts of the two engaging portions 35a and 35b are slightly increased. A change that is formed differently and is normally engaged with the end surface 14a of the carrier tape 14 at one point is substantially within the scope of the technical idea of the present invention.

  Further, in the above-described embodiment, the notch portion 27 formed of the two engagement recess portions 27a and 27b formed in the carrier tape 14 is formed, and the two engagement portions that engage with the engagement recess portions 27a and 27b are formed. Although 35a and 35b were formed in the engaging member 33, the number of engaging recessed parts and engaging parts is not limited to two, and may be plural. When the number of the engagement recesses and the engagement portions is, for example, three, by forming two openings 38 in the engagement lever portion 35 with an interval in the longitudinal direction of the carrier tape 14, A total of three engaging portions can be easily formed at both end portions of the two openings 38 (the inner end portions of the two openings 38 are common portions).

  Further, the number of engagement points that engage with the end surface 14a of the carrier tape 14 is infinite, that is, a single notch and engagement portion having a length continuous in the longitudinal direction of the carrier tape. In addition, “engage at least at two or more points” in claim 1 includes these forms.

  Furthermore, in the above-described embodiment, the example in which the notch portion 27 including the two engagement recesses 27a and 27b is formed on the end portion 14A1 side of the first carrier tape 14A has been described. Can also be formed on the start end 14B1 side of the second carrier tape 14B.

  Thus, the specific configuration described in the above-described embodiment is merely an example of the present invention, and the present invention is not limited to such a specific configuration. Of course, various embodiments can be employed without departing from the scope.
