Description

  The present invention relates to an electronic component supply apparatus and an electronic component supply method used in a component mounting machine constituting a board production line, and more particularly to an apparatus and method using a tray.

  As a facility for manufacturing boards on which a wide variety of electronic components are mounted, it has become common to construct a board production line by connecting screen printing machines, component mounting machines, reflow machines, inspection machines, etc. with a transport device. Yes. Among these, the component mounter is mainly configured by an electronic component supply device that supplies electronic components and a component transfer device that transfers the supplied electronic components to a predetermined position on the substrate. Electronic component supply devices are roughly classified into a reel method and a tray method, which are selectively used according to the form of the electronic component. The reel-type supply device is suitable for a relatively small resistor or capacitor called a chip component, and employs a structure in which a reel-like tape holding the chip component is pulled out by a feeder. The tray-type supply device is suitable for relatively large electronic parts such as IC parts, and employs a structure in which a tray on which electronic parts are placed is pulled out from a magazine.

  A tray unit 1 which is a first embodiment of an electronic component supply apparatus according to the present invention will be described with reference to FIGS. FIG. 1 is a cross-sectional view illustrating the apparatus configuration of the tray unit 1 of the first embodiment. As shown in the figure, the tray unit 1 is configured such that a transfer magazine 3 is housed in the upper side of the main body box 2 and a supply magazine 4 is housed in the lower side of the main body box 2. Both magazines 3 and 4 each have a plurality of slots SL3 and SL4 for setting a pallet PL on which a tray on which electronic components are loaded is placed. Each pallet PL is provided with an unillustrated barcode representing a pallet ID for identification. On the other hand, a bar code reader (not shown) that reads a bar code is provided in each of the slots SL3 and SL4.

  In the first embodiment, the tray in the transfer magazine 3 is referred to as a transfer tray 5, and the tray in the supply magazine 4 is referred to as a supply tray 6. Each of the magazines 3 and 4 includes a fixed nut, a feed screw that rotates by being screwed to the fixed nut, and an elevating mechanism that includes a motor that drives the feed screw, and is independently raised and lowered. . In FIG. 1, the transfer magazine 3 is in a state where parts can be supplied at a half lowered position, and the replenishment magazine 4 is lowered to the lower limit so that the pallet PL can be taken in and out.

  Doors 21 and 22 are respectively provided at the upper and lower portions of the front surface (the left surface in the drawing) of the main body box 2 so that the pallet PL can be taken in and out of the raised transfer magazine 3 and the lowered supply magazine 4 respectively. It has become. The operation of placing the replenishment tray 6 loaded with electronic components on the pallet PL and setting the pallet PL in the slot SL4 of the replenishment magazine 4 corresponds to the replenishment operation of the electronic components. In addition, an operation input unit 23 having various operation buttons and the like is provided at a substantially central height on the front surface of the main body box 2.

  On the other hand, a pallet drawer table 7 corresponding to a component supply unit is provided at the substantially central height of the rear surface of the main body box 2. The pallet drawer table 7 normally moves the pallet PL and the transfer tray 5 pulled out from the slot SL3 of the transfer magazine 3 to the suction station of the component transfer device 91, and after the electronic components are sucked and supplied. Returns the pallet PL and the transfer tray 5 to the original slot SL3. However, in response to an instruction from the component transfer device 91, the pallet drawer table 7 returns the pallet PL, on which the empty transfer tray 5 is placed, to the slot SL4 of the supply magazine 4 and the slot of the supply magazine 4 The pallet PL on which the replenishment tray 6 is placed may be pulled out from SL4 and returned to the slot SL3 of the transfer magazine 3. That is, the pallet drawer table 7 also serves as a tray diversion means for diverting the supply tray 6 to the transfer tray 5.

  FIG. 2 is a diagram for explaining a control structure of the component mounter 9 including the tray unit 1 and the component transfer device 91. The tray unit 1 and the component transfer device 91 individually have a control unit. In addition, a host computer 8 is provided to manage the entire board production line including the component mounter 9 in an integrated manner. Further, a personal digital assistant (PDA) 92 is used to present and guide information of the host computer 8 to the operator. In this control structure, the following control is performed.

  When the operator places a tray on the pallet PL, a correspondence relationship between the pallet ID for identifying the pallet PL, the component type of the electronic component on the tray, and the number of loaded items is registered in the host computer 8 in advance. Next, when the operator sets the pallet PL in the slots SL3 and SL4 of the transfer magazine 3 or the replenishing magazine 4 of the tray unit 1, the bar code reader provided in the slots SL3 and SL4 is attached to the pallet PL. Read the barcode representing the ID. Thereby, the control unit of the tray unit 1 recognizes the correspondence between each pallet PL and each of the slots SL3 and SL4. Information on the correspondence between the pallet ID and the positions of the slots SL3 and SL4 is transmitted to the host computer 8 via the component transfer device 91 as indicated by an arrow F1 in the figure. Based on the received correspondence information between the pallet ID and the positions of the slots SL3 and SL4, and the correspondence relationship between the registered pallet ID and the component type and the number of loaded electronic components, the host computer 8 Know the location type and number of loads.

  Further, the host computer 8 transmits information on the correspondence relationship between the positions of the slots SL3 and SL4 and the component types to the component transfer device 91 as indicated by an arrow F2 in the figure. Based on the received information, the component transfer device 91 transmits magazine control and pallet control commands to the tray unit 1 as shown by an arrow F3 in the figure to transfer electronic components. That is, the component transfer device 91 sequentially transmits a command to pull out the pallet PL to the pallet pull-out table 7 from the slot SL3 of the transfer magazine 3 corresponding to the desired component type, and from the transfer tray 5 on the pallet PL. Electronic components are supplied. In addition, when the number of electronic components loaded on the transfer tray 5 is insufficient and the components run out, the component transfer device 91 issues a command to divert the supply tray 6 of the supply magazine 4 as will be described later. It is supposed to send. Further, the parts transfer device 91 transmits production information to the host computer 8 as indicated by an arrow F4 in the figure. The production information includes information on the number of substrates for which transfer of electronic components has been completed and information on the number of supplied electronic components.

  The host computer 8 determines a replenishment guide for replenishment of parts from the received production information, the part type and the number of loaded electronic parts already known, and as shown by an arrow F5 in the figure, the parts transfer device 91 and It transmits to the portable information terminal 92. In other words, the host computer 8 sequentially subtracts the quantity used for transfer from the initial number of electronic parts loaded on the set tray to obtain the existing number of loaded parts, and predicts that the parts will run out. That is, the host computer 8 has a function corresponding to a component management unit as a part of the tray unit 1. Of course, this function may be performed by the control unit of the tray unit 1. Details of the prediction and replenishment guidance functions of the host computer 8 as parts management means will be described in detail later.

  Next, an electronic component supply method using the tray unit 1 of the first embodiment will be described using a specific example with reference to the flowchart of FIG. As shown in FIG. 3, the electronic component supply method has four steps of an initial setting step S1, a longest replenishment plan step S3, a tray diversion step S4, and a replenishment execution step S5. The longest replenishment plan step S3 and the tray diversion step S4 and replenishment execution step S5 are repeated. FIG. 4 is a diagram for explaining the initial setting step S1, in which (1) shows the initial state, (2) shows the middle of the initial setting, and (3) shows the end of the initial setting. FIG. 5 is a diagram for explaining the tray diversion step S4, and (1) to (4) show temporal transitions. FIG. 6 is a diagram for explaining the longest supply plan step S3, and FIG. 7 is a diagram for explaining the supply execution step S5. In the figure, each tray indicates the type of component loaded, and the number of existing loads and the time during which transfer can be continued for each tray, which will be described later, are shown in parentheses.

  In the specific example, as shown in the initial state in which the tray of FIG. 4A is not set, the transfer magazine 3 and the replenishment magazine 4 of the tray unit 1 are each seven pieces of first to seventh. Slots SL31 to SL37 and SL41 to SL47. Also, consider a case where the electronic component of the six component types A to F is mounted on the substrate by the component mounter 9 in a number N = 5. The transfer required time T1 required for transferring these six types of electronic components is 2 minutes per substrate. The loading numbers nA to nF of the component types A to F loaded on the transfer tray 5 and the replenishment tray 6 are the loading number nA = 300 for the component type A, and the loading number nB = 100 for the component type B, respectively. The loading number nC = 20 for the component type C, the loading number nD = 10 for the component type D, the loading number nE = 50 for the component type E, and the loading number nF = 50 for the component type F. Then, when considering in units of trays, the transferable continuous time TA of the component type A is obtained by the following equation, and TA = 120 minutes.

Transfer continuation possible time TA = transfer required time T1 × (loading number nA / mounting number N)
= 2 × (300/5)
= 120
Similarly, the transfer continuation possible times TB to TF of the component types B to F are TB = 40 minutes, TC = 8 minutes, TD = 4 minutes, TE = 20 minutes, TF = 20 minutes, respectively. Become. Of course, if an electronic component is supplied to the component transfer device 91 and the existing number of loads is reduced, the transfer continuation possible time TA to TF is also reduced accordingly.

  In step S11 in the initial setting step S1 in FIG. 3, the operator first prepares transfer trays 5A to 5F on which electronic components of the respective component types A to F are respectively loaded. Set to 7 slots SL32 to SL37. Thereby, the tray unit 1 shifts from the initial state of FIG. 4 (1) to the state of (2). In the state of (2), the host computer 8 grasps the component types and the number of stacks of the transfer trays 5A to 5F as described above. Therefore, in step S12, the host computer 8 predicts the order in which the number of electronic components to be loaded is short after the component transfer device 91 starts the component transfer operation, and loads the component on the supply tray 6 to be supplied. The type is obtained and presented to the operator.

  In the specific example of FIG. 4, the host computer 8 predicts the order in which the number of electronic components is insufficient as follows. Since the component type D is insufficient 4 minutes after the start of the component transfer operation, if the component type D is replenished, the component types D and C are simultaneously insufficient after 8 minutes, so these two component types are replenished. Further, the missing component type D is replenished after 12 minutes, and the deficient component types D and C are replenished after 16 minutes. By performing such replenishment, the so-called component breakage, that is, the tray unit 1 cannot be supplied due to a shortage of electronic components, can be slowed down most. Based on this, the host computer 8 presents the component types loaded on the supply tray 6 as component types D, D, C, D, D, and C.

  In accordance with this presentation, in step S13, the operator transfers the four transfer trays 61, 62, 64, 65 loaded with the component type D and the two transfer trays 63, 66 loaded with the component type C. Are set in the second to seventh slots SL42 to SL47 of the supply magazine 4. Thereby, the process proceeds to the end of the initial setting in FIG. The first slot SL41 of the replenishing magazine 4 is vacant for collecting empty trays as will be described later.

  Next, when the operator issues a start command in step S2, the component transfer operation by the component transfer device 91 is started. At this point, the host computer 8 performs the longest replenishment planning step S3. The tray diversion step S4 will be described first.

  When the component transfer operation progresses smoothly, as shown in step S41 in the tray transfer step S4, there is a case where the number of existing stacks is insufficient in any of the transfer trays (any one of 5A to 5F). . Then, in step S42, the component transfer device 91 instructs the tray unit 1 to collect the transfer tray, that is, the empty tray whose existing stack number is insufficient, in the supply magazine 4, and to load electronic components of the same component type. The replenishment tray (any one of 61 to 66) is diverted.

  In the specific example, the transfer to the two substrates ends 4 minutes after the component transfer operation is started following the end of the initial setting in FIG. As shown in FIG. 5 (1), the number of existing stacks decreases by 10 for each of the transfer trays 5A to 5F of the transfer magazine 3, and the transfer continuation possible time TA to TF for each tray. Decreases by 4 minutes each. In the transfer tray 5D of the component type D, the existing number of loads becomes zero and an empty tray is formed. The empty tray is collected in the first slot SL41 of the supply magazine 4 as indicated by an arrow J1. Instead, the supply tray 61 loaded with the same component type D in the second slot SL42 is pulled out and returned to the transfer magazine 3 as indicated by the arrow J2. That is, the supply tray 61 is diverted to the transfer tray 5D.

  8 minutes after the elapse of 4 minutes, as shown in FIG. 5B, the transfer trays 5D and 5C of the component types D and C of the transfer magazine 3 become empty trays. Here, first, the empty tray of the component type D is collected in the second slot SL42 of the replenishing magazine 4 as indicated by the arrow J3. Instead, the same component type D of the third slot SL43 is selected as indicated by the arrow J4. The loaded supply tray 62 is returned to the transfer magazine 3 and diverted to the transfer tray 5D. Next, the empty tray of the part type C is collected in the third slot SL43 of the replenishing magazine 4 as indicated by the arrow J5. Instead, the same part type C of the fourth slot SL44 is loaded as indicated by the arrow J6. The replenishment tray 63 is returned to the transfer magazine 3 and diverted to the transfer tray 5C.

  Similarly, after 12 minutes, as shown in FIG. 5 (3), the transfer tray 5D for the component type D becomes an empty tray again, and the fourth slot of the supply magazine 4 as shown by the arrow J7. Instead, the supply tray 64 loaded with the same component type D in the fifth slot SL45 is returned to the transfer magazine 3 and transferred to the transfer tray 5D as indicated by an arrow J8. . After another 16 minutes, as shown in FIG. 5 (4), the transfer trays 5D and 5C of the component types D and C of the transfer magazine 3 become empty trays again. Here, first, the empty tray of the component type D is collected in the fifth slot SL45 of the supply magazine 4 as indicated by the arrow J9, and instead the same component type D of the sixth slot SL46 is selected as indicated by the arrow J10. The loaded supply tray 65 is returned to the transfer magazine 3 and diverted to the transfer tray 5D. Next, the empty tray of the part type C is collected in the sixth slot SL46 of the replenishing magazine 4 as indicated by the arrow J11. Instead, the same part type C of the seventh slot SL47 is loaded as indicated by the arrow J12. The replenishment tray 66 is returned to the transfer magazine 3 and diverted to the transfer tray 5C.

  In the specific example, the set six supply trays 61 to 66 are all diverted to the transfer tray 16 minutes after the start if the component transfer operation proceeds smoothly. The host computer 8 can predict a series of tray diversion processes shown in FIG. Further, the host computer 8 runs out of the replenishment trays 61 to 66 and cannot supply any of the component types (when the component runs out as the tray unit 1), and the existing component types A to F at that time. The number of loads can be predicted. FIG. 6 (1) shows a situation in which it is predicted that parts types F, E, and D will run out at the same time 20 minutes after 4 minutes have passed since FIG. 5 (4). The 20 minutes is the first transfer continuation possible time T2 in the specific example.

  In step S31 in the longest replenishment planning step S3, the host computer 8 predicts in advance the transfer continuation possible time T2 = 20 minutes. Further, the host computer 8 can obtain the component type of the supply trays 61 to 66 to be set next time based on the existing number of loaded components A, B, and C shown in FIG. That is, the component types F, E, and D, which are out of components in FIG. 6 (1), should be replenished first, and thereafter, the component types D, C, and D should be replenished according to the same prediction as in FIG. 6 (2). Predict that there is. The predicted transfer continuation possible time T2 and the information on the part type to be set are presented to the operator as supply guidance. Further, in step S32, before the transfer continuation possible time T2 = 20 minutes elapses, for example, a notice time is set 18 minutes after the start of the component transfer operation with a margin of 2 minutes. When the advance notice time is reached in step S33, in step S34, the host computer 8 informs the operator of the stop notice. For example, the message “The parts will run out in 2 minutes. Please set the supply trays for parts types F, E, D, D, C, D” is displayed.

  Next, when the above-mentioned stop notice is guided to the component transfer device 91 and the portable information terminal 92 in step S51 of the replenishment execution step S5, the operator who sees this notices the electronic of the component type presented in step S52. A supply tray loaded with parts is set in the supply magazine 4. In the specific example, as shown in FIG. 7, the empty trays in the first to sixth slots SL41 to SL46 of the supply magazine 4 are taken out, and the six supply trays 61 to 66 are removed from the second to seventh slots SL42 to SL42. Set to SL47. This parts replenishment can be performed before and after the stop notice 18 minutes later, and after 20 minutes, the state shown in FIG. Even if replenishment is attempted before 16 minutes, the replenishment work becomes inefficient because the replenishment trays 65 and 66 that have not been diverted remain in the replenishment magazine 4. Further, if the replenishment is later than 20 minutes later, the component is cut out, the component transfer operation is interrupted, and the board manufacturing efficiency is lowered.

  Finally, in step S6, the host computer 8 determines whether or not the number of substrates that have been transferred has reached a desired number based on the production information transmitted from the component transfer device 91, and if not, The operation after the longest replenishment plan step S3 is repeated, and when it is reached, the operation is terminated and the operator is informed accordingly.

  The second transfer continuation possible time after FIG. 6 (2) is 12 minutes. The time for which transfer can be continued each time after the parts are replenished varies depending on the combination of the number of existing stacks of the transfer trays 5A to 5F and the types of parts of the supply trays 61 to 66.

  In the tray unit 1 of the first embodiment, the host computer 8 corresponding to the component management means is supplied to each of the transfer trays 5A to 5F set in the transfer magazine 3 and the supply magazine 4. The number nA to nF of electronic components loaded on the trays 61 to 66 is grasped. Based on this, the host computer 8 predicts the transfer continuation possible time T2, obtains and presents the component types of the replenishment trays 61 to 66 that maximize the next transfer continuation possible time, and further notifies the stoppage. To guide you. Therefore, the operator can efficiently and systematically supply parts with minimum effort according to the presentation and guidance, and the supply time interval can be maximized.

  Further, the apparatus includes a transfer magazine 3 that mainly supplies electronic components to the component transfer device 91, a supply magazine 4 that can convert the supply trays 61 to 66, and a pallet drawer table 7 that also serves as a tray transfer means. . Accordingly, by setting the supply trays 61 to 66 of the appropriate component types presented at the appropriate supply timing guided by the operator in the supply magazine 4, the component transfer operation is not interrupted, and the board is manufactured. Very high efficiency.

  In the first embodiment, replenishment guidance (presentation of parts to be replenished and advance notice of stoppage) is provided on the premise that all of the replenishment trays 61 to 66 are used up. The replenishment guidance may be provided. In other words, the host computer 8 as the component management means may present the component type corresponding to the number of slots that can be replenished at the time when the operator's request is received, and the transfer continuation possible time from that point. In this way, when there is another job at the time of the stop notice, the operator can replenish parts in advance, and efficient parts replenishment flexibly corresponding to the convenience of the operator.

  Next, the tray unit 10 of the second embodiment in which the replenishment time interval is constant will be described with reference to FIGS. The tray unit 10 of the second embodiment has the same apparatus configuration and control structure as the tray unit 1 of the first embodiment shown in FIGS. 1 and 2, and the function of the host computer 8 as a component management means is different. FIG. 8 is a flowchart illustrating an electronic component supply method using the tray unit 10 of the second embodiment. As shown in the figure, the electronic component supply method of the second embodiment has four steps of an initial setting step S1, a constant supply plan step S7, a tray transfer step S4, and a supply execution step S8, and a tray transfer step S4, and The replenishment execution step S8 is repeated. FIG. 9 is a diagram for explaining the operation steps S1, S7, S4, and S8 in the second embodiment targeting a board on which electronic components of the same six component types A to F as in the first embodiment are mounted. , (1) to (6) show temporal transitions.

  In the electronic component supply method of the second embodiment, the initial setting step S1 (S11 to S13) in FIG. 8 is the same as that of the first embodiment, and the initial setting end state in FIG. ) Next, in step S71 in the fixed supply plan step S7, the operator inputs and sets a fixed supply time interval T3. Next, in step S72, the host computer 8 determines in advance whether or not a desired quantity of electronic components can be supplied when the components are supplied at the set supply time interval T3. If NO, in step S73, the host computer 8 sequentially shortens the replenishment time interval T3 to obtain a possible replenishment time interval T3. In step S74, the determined replenishment time interval T3 and the component types of the replenishment trays 61 to 66 for each component replenishment are presented. That is, in the second embodiment, on the premise that parts are replenished at a constant replenishment time interval T3, the part type to be replenished every time is obtained in advance. While the longest supply plan step S3 is repeated in the first embodiment, the constant supply plan step S7 of the second embodiment is an operation only once. The constant supply plan step S7 will be described later in a specific example.

  Next, when the operator issues a start command in step S2, the component transfer operation by the component transfer device 91 is started. If the component transfer operation progresses smoothly, there may be a case where the number of existing stacks is insufficient in one of the transfer trays (any of 5A to 5F), and in response to this, the tray transfer step S4 (S41 and S42). The diversion tray (any of 61 to 66) is diverted in the same manner as in the first embodiment.

  Next, when the replenishment time interval T3 elapses in step S81 of the replenishment execution step S8, in step S82, the operator places a replenishment tray (a part or all of 61 to 66) on which electronic components of the presented component type are loaded. Is set in the supply magazine 4. Finally, in step S6, the host computer 8 determines whether or not the number of substrates that have been transferred has reached a desired number based on the production information transmitted from the component transfer device 91, and if not, The tray diversion step S4 and the replenishment execution step S8 are repeated, and when it is reached, the operation is terminated and the operator is informed accordingly.

  The electronic component supply method of the second embodiment will be described with reference to a specific example of FIG. In a specific example, it is assumed that the replenishment time interval T3 = 10 minutes has been input. The host computer 8 predicts that the tray unit 10 operates as in (2) to (6) after the end of the initial setting in FIG. More specifically, (2) by 10 minutes (before supply), the transfer tray 5D for the component type D of the transfer magazine 3 becomes an empty tray twice, and the transfer tray 5C for the component type C is 1 The three empty trays are collected in the first to third slots SL <b> 41 to SL <b> 43 of the supply magazine 4. The supply trays 61 to 63 in the second to fourth slots SL42 to SL44 of the supply magazine 4 are sequentially diverted so as to be replaced. At this time, the supply trays 64 and 65 can be diverted to the component type D that becomes an empty tray after 12 minutes and 16 minutes, and the supply tray for the component type C that becomes an empty tray after 16 minutes. 66 can be diverted. Therefore, the supply trays 61, 62, 63 corresponding to the component types F, E, and D that are predicted to become empty trays after 20 minutes are prepared in advance, and the second to second of the supply magazine 4 after 10 minutes. When set in the fourth slots SL42 to SL44, the state shown in FIG.

  Furthermore, the supply tray 64 (part type D), 65 (part type D), 66 (part type C), and 61 (part type F) of the supply magazine 4 is reached by 20 minutes after the parts transfer operation continues. 62 (part type E) and 63 (part type D) are diverted in this order, and the state shown in FIG. After that, replenishment trays 61 to 66 corresponding to the component types D, C, D, D, C, and D to be empty trays are prepared in advance, and after 20 minutes, the second to seventh slots SL42 of the replenishment magazine 4 are prepared. When set to .about.47, the state shown in FIG. After 30 minutes thereafter, the supply tray 61 (part type D), 2 (part type C), 63 (part type D) of the supply magazine 4 are diverted in this order, and the state shown in FIG. It becomes.

  Then, there are replenishment trays 64 to 66 that can be diverted in correspondence with the component types D, C, and D that will become empty trays, and the component transfer operation is not interrupted until after 40 minutes. However, since there are not enough five component types B to F after 40 minutes, it is necessary to set five supply trays in the supply magazine 4, whereas the first to 30th points after 30 minutes. Only the fourth slots SL41 to SL44 are vacant. Eventually, after 40 minutes, the replenishment tray is insufficient and the component transfer operation is interrupted.

  When the desired number of electronic components is achieved within the 40 minutes, the host computer 8 has a desired number of substrates of 20 or less (since the required transfer time T1 = 2 minutes per one). At this time, the set input 10 minutes is set as a final replenishment time interval T3. Further, when the desired number of electronic components cannot be achieved in 40 minutes (the number of substrates exceeds 20), the host computer 8 reduces the replenishment time interval T2 to 9 minutes, 8 minutes,. The parts supply plan corresponding to FIG. 9 is predicted again, and the longest and constant supply time interval T3 at which the desired number of electronic parts is achieved is obtained. This is the specific content performed in the constant supply plan step S7.

  In the tray unit 10 of the second embodiment, the host computer 8 corresponding to the component management means is supplied to each of the transfer trays 5A to 5F set in the transfer magazine 3 and the supply magazine 4. The number nA to nF of electronic components loaded on the trays 61 to 66 is grasped. Based on this, the host computer 8 can supply a desired quantity of electronic components under the condition that the supply trays 61 to 66 are set in the supply magazine 4 at a predetermined fixed supply time interval T3. Is determined in advance, and if it is not possible, the fixed constant replenishment time interval T3 that can be obtained is obtained. Therefore, the operator can replenish electronic components systematically at a constant replenishment time interval T3 according to the presentation without making a complicated prediction. Further, the component transfer operation is not interrupted, and the board manufacturing efficiency is extremely high.

  In the second embodiment, when the set replenishment time interval T3 is too long, the short replenishment time interval may be allowed instead of shortening it. For example, in the specific example described with reference to FIG. 9, if the replenishment time interval T3 = 10 minutes and the parts are replenished after 10 minutes, 20 minutes, and 30 minutes, the parts run out after 40 minutes. Here, if the next replenishment time interval after 30 minutes is exceptionally set to 8 minutes and parts are replenished after 38 minutes, then the parts can be replenished after 10 minutes at 48 minutes. This 8 minutes is shorter than the set replenishment time interval T3 = 10 minutes, but it is possible to return to the original replenishment time interval T3 without causing parts to run out.

Next, a tray unit 11 according to a third embodiment including only a single transfer magazine 3 will be described with reference to FIG. FIG. 10 is a diagram illustrating a specific example of the apparatus configuration and operation of the tray unit 11 of the third embodiment. In the figure, each tray indicates the type of the loaded component, and the number of existing loads and the transfer continuation possible time are indicated in parentheses.
As shown in the initial state of FIG. 10 (1), the tray unit 11 stores the transfer magazine 3 having the seven slots SL 31 to SL 37 in the first to seventh inside the main body box 2. It is configured. The setting of the pallet PL on which the tray is placed in each of the slots SL31 to SL37, and the provision of an elevating mechanism, a door, an operation input unit, and the like are the same as in the first embodiment. Among the trays, the trays 5G, 5H, and 5I for supplying electronic components directly to the component transfer device 91 are the transfer trays 5G, 5H, and 5I, and those that wait for being diverted to the transfer tray 5 are the supply trays 61 to 64. It is. Further, the control structure of the tray unit 11 is the same as that shown in FIG. 2, and a host computer 8 and a portable information terminal 92 corresponding to parts management means are provided. In the tray unit 11, in consideration of safety, the transfer operation of the electronic components is interrupted when the supply trays 61 to 64 are set in the transfer magazine 3, and the host computer 8 transfers the transfer. Control is performed so that the operation continuation time is maximized.

  Next, the operation of the tray unit 11 of the third embodiment will be described based on a specific example. In a specific example, it is assumed that three types of electronic components of component types G, H, and I are each mounted on the substrate by N = 5. In addition, the transfer required time T4 required to transfer these three component types G, H, and I is set to 2 minutes per substrate. The loading numbers nG to nI of the component types G, H, and I that can be loaded on the transfer trays 5G, 5H, and 5I and the replenishment trays 61 to 64 are the component type G and the loading number nG = 30, respectively. The loading number nH = 30 and the component type I is the loading number nI = 15. Then, the transfer continuation possible times TG to TI in units of trays are TG = 12 minutes, TH = 12 minutes, and TI = 6 minutes, respectively. Of course, if the electronic component is supplied to the component transfer device and the number of existing loads is reduced, the transfer continuation possible times TG to TI are also reduced accordingly.

  In FIG. 10, first, the operator prepares transfer trays 5 </ b> G to 5 </ b> I loaded with electronic components of the respective component types G to I, and sets them in the first to third slots SL <b> 31 to SL <b> 33 of the transfer magazine 3. As a result, the tray unit 1 shifts from the initial state where the tray of FIG. 10A is not set to the state of (2). In the state of (2), the host computer 8 grasps the component type and the number of loads of each of the transfer trays 5G to 5I, and the number of electronic components is insufficient after the component transfer device starts the component transfer operation. The order to be performed is predicted, and the type of parts to be supplied is obtained and presented to the operator. Specifically, since component type I is insufficient 6 minutes after the start of the component transfer operation, if it is replenished, it can be predicted that 3 component types G, H, and I will be insufficient simultaneously 12 minutes later. Present to prepare G, H, and I supply trays. In accordance with this presentation, the operator prepares four transfer trays 61 to 64 each loaded with electronic components of component types I, G, H, and I, and sets them in the fourth to seventh slots SL34 to SL37. Thereby, the process proceeds to the end of the initial setting in FIG.

  Next, when the operator issues a start command, the component transfer operation by the component transfer device is started. At this time, the host computer 8 predicts the transfer continuation possible time T5 until one of the component types (any of G to I) is insufficient. The operation of tray transfer will be described first.

  When the component transfer operation progresses smoothly, there may be a case where the number of existing stacks is insufficient in any of the transfer trays (any of 5G to 5I). In a specific example, as shown in FIG. 10 (4), the transfer tray 5I for the component type I becomes an empty tray after 6 minutes. Then, the control unit of the component transfer apparatus changes the supply source of the component type I from the third slot SL33 to the fourth slot SL34. As a result, the component type I is supplied from the supply tray 61, and the supply tray 61 is diverted to the transfer tray 5I. That is, in the third embodiment, the tray diversion is performed according to a command from the control unit without changing the tray position. That is, the control unit of the component transfer device plays a role of tray diversion means.

  Subsequently, after 12 minutes, as shown in FIG. 10 (5), the transfer trays 5G and 5H and the new transfer tray 5I simultaneously become empty trays, and the replenishment trays 62 to 64 are diverted respectively. The Then, after 18 minutes, as shown in FIG. 10 (6), the new transfer tray 5I becomes an empty tray, and the parts transfer operation is interrupted. That is, the transfer continuation possible time T5 = 18 minutes.

  The host computer 8 can predict a series of tray diversion processes from (4) to (6) at the end of the initial setting in FIG. 10 (3), and can predict a transfer continuation possible time T5 = 18 minutes. Furthermore, in the state shown in FIG. 10 (6) after 18 minutes, the missing component type I is first replenished, and then the order of the missing component types can be predicted. Then, the transfer continuation possible time T5 = 18 minutes and the order of the missing component types are presented to the operator as supply guidance and stop notice. Therefore, the operator can prepare the replenishment tray to be set next, and if the component transfer operation is interrupted after 18 minutes, the operator can immediately set it in the transfer magazine 3. In the specific example of FIG. 10 (6), five empty trays are collected, and five replenishment units are loaded with electronic components of the missing component types in the first to fourth and seventh slots SL31 to SL34 and SL37. Set the tray.

  In the tray unit 11 of the third embodiment, the order in which the number of electronic components is insufficient is predicted, and the replenishment trays are prepared accordingly. Therefore, the limited number of replenishment trays are used up effectively and the transfer is continued. The possible time T5 can be maximized. In addition, since the transfer continuation possible time T5 and the insufficient component type are presented in advance, the operator can prepare the replenishment tray systematically and efficiently. Furthermore, since the replenishment tray can be set immediately after the transfer continuation possible time T5 obtained in advance, the transfer interruption time can be shortened.

  In each embodiment, the control structure is not limited to the one having the host computer 8 shown in FIG. 2, and the function of the component management means is controlled by the control unit of the component mounter 91 or the tray units 1, 10, 11. You may make it carry out by a part. In addition, the correspondence relationship between the pallet ID, the electronic component type and the number of loaded parts is registered in the host computer 8 in advance, and the operator reads the pallet ID when the pallet PL is set in the slots 3 and 4. When the pallet PL is set, the type and number of electronic components on the pallet PL may be input with a barcode scanner or the like. Further, the number of slots of the transfer magazine 3 and the replenishment magazine 4 is not limited to seven and is arbitrary.

  In the first and second embodiments, only the transfer trays 5A to 5F are set in the transfer magazine 3, but in an extra empty slot (the first slot SL31 in the embodiment). A replenishment tray 6 may be set. In addition, a spare magazine may be provided separately from the transfer magazine 3 and the replenishing magazine 4, and the spare magazine in which a plurality of replenishing trays are set may be replaced with the replenishing magazine 4 to supply parts. In addition, the present invention can be applied in various ways.
