The read / write head 52 is capable of reading and writing information with respect to the small storage device 51i.
[0026]
  In addition, for example, an external device as shown in FIG. 3 is provided in order to write information necessary for the small storage device 51 when the tray 5 is fixed to the pallet 8 as a pre-process. That is, the external device shown in FIG. 3 includes a management device 53 composed of a personal computer, a barcode reader 56 for reading a barcode 55 attached to the front surface of the parts shelf 54, and a device for writing information to the small storage device 51.

[0027]
  The component shelf 54 stores a large number of trays holding components in each shelf according to component type, and a bar code 55 that records information on the tray is attached to the front of each shelf.
[0028]
  FIG. 4 shows a configuration of a controller 60 as a control device that performs determination of information read from the small storage device 51 by the read / write head 52 and control of the take-out mechanism 3 corresponding thereto. The controller 60 is mounted on the mounting machine M as shown in FIG. 2 and controls the tray component supply device 1 in conjunction with the control of the mounting machine M. In FIG. Is omitted, and only the configuration related to the control of the tray component supply apparatus 1 is shown.
[0029]
  In this figure, the controller 60 includes an arithmetic processing unit 61 constituted by a CPU, a component data storage unit 62 for storing component data, and an extraction order storage unit 63 for storing the component extraction order from the tray storage box 2. And a motor control unit 64 that controls various motors mounted on the tray component supply apparatus 1 and an external input / output unit 65.
[0030]
  The motor control unit 64 includes two motors (X-axis motor and Y-axis motor) 37 and 40 of the motor (H motor) 19 of the drawer device 10, the motor (Z-axis motor) 25 of the lifting device and the component transfer device 30. In addition, the motor 46 for conveying parts is controlled. The external input / output unit 65 inputs a signal from the read / write head 52 and a signal from various sensors 66 provided in the tray component supply apparatus 1, and writes data to the read / write head 52 as necessary. The control signal is output to the various drive units other than the motors 19, 25, 37, 40, and 46 described above.
[0031]
  The arithmetic processing unit 61 determines the content of the information read by the read / write head 52 based on the data obtained from the read / write head 52 via the external input / output unit 65, and according to the determination result, the motor control unit The take-out mechanism 3 is controlled by controlling the motors 19, 25, 37, 40, etc. via 64. For example, as will be described in detail later with reference to a flowchart, the type of the component is determined based on the information read by the read / write head 52, and it is determined whether the component matches the component to be extracted. The take-out mechanism 3 is controlled so as to be completed, and the drive of the take-out mechanism 3 is stopped when the discriminated part and the part to be taken out do not match. Further, an external display unit 66 is connected to the arithmetic processing unit 61, and an error display or the like when the above mismatches can be performed by the display unit 66.
[0032]
  The aboveReference formNext, the operation of the apparatus will be described.
[0033]
  First, when the tray 5 holding a specific part is set on the pallet 8 of the tray storage box 2, the specific stage pallet 8 is taken out from the tray storage box 2 to the outside in the parts shelf 54 shown in FIG. The tray 5 holding the specific parts is taken out and fixed on the pallet 8. At this time, the barcode reader 56 is operated so that the tray of the parts shelf 54 is attached to the front of the taken-out shelf. The bar code 55 is read, and information such as the part name is sent to the management device 53. Further, when the handy unit 57 is operated, the information is sent from the management device 53 to the handy unit 57 and written into the small storage device 51.
[0034]
  Here, the information read from the barcode 55 and written in the small storage device 51 includes at least information for identifying the type of the component, such as the name of the component, and matrix information of the component arrangement of the tray. (Information indicating how many columns the parts are arranged vertically and horizontally) is also included. More preferably, the component suction start position is also written in the small storage device 51. The component suction start position is, for example, one end side in the X direction and one end side in the Y direction of the matrix arrangement of components in the case of a new tray from which components have not been removed, and in the case of a tray in which some components have already been removed. The point is changed according to the extraction order.
[0035]
  If there is no information in the bar code 55, the component suction start position may be written in the small storage device 51 by giving information to the handy unit 57 by an input operation or the like in the management device 53.
[0036]
  In this way, information indicating the type of the component can be easily and definitely obtained by processing outside the tray storage box 2 at the time of setup, and the small memory provided in the pallet 8 on which the tray 5 of the component is set. Written to the device 51. When such external processing is completed, the pallet 8 on which the tray 5 is installed is stored in the tray storage box 2.
[0037]
  When the components are supplied from the tray component supply device 1 to the mounting machine M after the above-described setup operation is completed, the controller 60 automatically performs processing as shown in the flowchart of FIG.
[0038]
  That is, first, in step S1, a request for component supply from the machine (mounting machine M) is waited. When this request is made, the pallet 8 corresponding to the specified component is specified according to the program and the pallet is pulled out. Control is performed (step S2). In this case, according to the structure of the tray component supply apparatus 1 as shown in FIG. 1, after the elevating device 20 is driven, the height of the drawer device 10 is adjusted to correspond to the specified pallet 8. The drawer device 10 is driven and the pallet 8 is pulled out.
[0039]
  Next, the information of the small storage device 51 on the drawn pallet 8 is read by the read / write head 52 (step S3), and the part 6 actually held on the tray 5 on the pallet 8 is checked from this information. Then, it is determined whether or not the actual part matches the designated part (step S4). If the actual part does not match the designated part in this determination, the drive of the take-out mechanism 4 is stopped and an error is displayed by the display unit 66 (step S5).
[0040]
  If it is determined in step S4 that the actual part matches the designated part, the drawer 10 is raised to a predetermined height position corresponding to the part transfer device 30 (step S6). Subsequently, the component suction head 31 of the component transfer device 30 moves to the coordinates of the component suction start position recorded in the small storage device 51 (step S7), and then the component suction head 31 descends to suck the component (step S7). S8).
[0041]
  When the component suction is completed, the component suction start position is incremented to the next point, and this next suction start position is recorded in the small storage means 51 (steps S9 and S10). At the same time, the component suction head 31 is moved onto the component support base 43, and the component suction head 31 is further lowered to transfer the component onto the component support base 43 (steps S11 and S12). Although the processing after the component transfer is omitted in FIG. 5, after the component transfer, the component on the component support base 43 is sent to the mounting machine M by driving the component conveying device 4.
[0042]
  By the processing as described above, a situation in which a component different from the specified component due to erroneous setup is supplied to the mounting machine M is surely prevented.
[0043]
  That is, trays 5 holding different types of components are placed on the pallets 8 in each stage of the tray storage box 2, and the trays 5 of which types are set on the pallets 8 in each stage. Such a tray arrangement is predetermined, but when the operator takes out the tray 5 from the parts shelf 54 and stores it in the tray storage box 2, the pallet 8 at a specific stage is different from the predetermined parts. There is a case where the tray 5 of a different kind of component is set by mistake. Even in the case of such erroneous setup, the barcode information is actually read on the pallet 8 by reading the barcode information using an external device as shown in FIG. 3 and writing the information to the small storage device 51. Information such as the component type for the tray 5 is recorded in the small storage device 51 provided in the pallet 8.
[0044]
  When the take-out mechanism 3 is operated to supply the designated part to the mounting machine M in accordance with the program, first, a pallet 8 corresponding to the designated part is selected based on a predetermined tray arrangement, and the pallet 8 is pulled out. The information is read out from the small storage device 51 at this time, and the component type of the tray 5 actually set on the pallet 8 is determined. If the part determined due to the above-mentioned erroneous setup is different from the designated part, an error is displayed and error processing such as stopping of the take-out mechanism 3 is performed, which is different from the designated part. Thus, the parts are surely prevented from being sent to the mounting machine M.
[0045]
  Further, when the part determined by the information from the small storage device 51 matches the designated part, the part is sucked by the part suction head 31 of the part transfer device 30 from the tray 5 on the drawn pallet 8. Then, it is transferred onto the component support base 43 of the component transport device 4.Reference formWhen the component suction start position is recorded together with the matrix information of the components on the tray in the small storage device 51 and the component suction start position is updated according to the component suction, the component transfer device The component suction and transfer operations by 30 are efficiently performed.
[0046]
  That is, if there is no information on the part suction start position, when some parts have already been taken out from the tray 5, the part suction head 31 first moves to the point after the parts are taken out, and the parts are picked up by the suction operation here. The operation of moving to the next point after detecting that it could not be picked up is repeated until the point where the part exists is wasted.Reference formIf the small storage device 51 is used to record and update the component suction start position as described above, the component suction head 31 can immediately move to the point where the component exists. Is as short as necessary.
[0047]
  Next, an embodiment of the present invention will be described. In the present embodiment, only the control when the component determined based on the read information by the read / write head 52 does not match the designated component is different, and the other control procedures and the configuration of the apparatus are the same as the above-described reference embodiment. It is. For this reason, below, only the part peculiar to this Embodiment (difference with a reference form) is demonstrated.
[0048]
In the above-mentioned reference form, as shown in FIG. 5, when the part determined based on the information read by the read / write head 52 with the specific pallet 8 pulled out does not match the designated part, an error display is performed. In this embodiment, if the identified part does not match the designated part, the pallet 8 is returned to the tray storage box 2 to place another pallet 8 in the present embodiment. With regard to the palette searching process for determining whether or not the part identified by the information read from the small memory 51 for the other pallet 8 matches the designated part, the identified part and the designated part match. Repeat until Then, even if the search process is performed for all the stages, when a part that matches the designated part is not found, an error is displayed and the operation of the take-out mechanism 3 is stopped.
