The print head 13 is formed with nozzles for ejecting ink on the lower surface facing the printing object 11. The ink ejected from the nozzles is supplied from an ink cartridge (not shown).

  As a general method of use, the printing apparatus 10 mounts the printing object 11 on the transport base 12 and transports it in the X direction, while reciprocating the print head 13 in the Y direction to eject ink from the nozzles. . With this operation, an image, characters, or the like is printed on the upper surface of the flat print object 11 such as paper facing the print head 13.

[Outline of structure of jig table device]
FIG. 2 is an embodiment showing a state where the jig table device 15 to which the present invention is applied is used for the printing device 10. In the figure, reference numeral 17 denotes a table 17 on which the printing apparatus 10 is placed.

  The jig table device 15 of this embodiment includes a guide unit 20 and an urging unit 30.

  The guide unit 20 is arranged between the transport table 12 and the print head 13 along the first direction X from the outside of the transportable region R of the transport table 12 to the transport table 12. Guide to move. The urging unit 30 urges the jig table 16 in a state in which the jig table 16 is pressed against the pressing member 21 provided on the transport table 12.

  This will be described in detail below.

[Details of structure of jig table device]
FIG. 3 is a diagram illustrating the urging unit 30 in the embodiment.

  In this example, the guide unit 20 includes a pair of left and right guide rails 24, and moves the jig table 16 along the first direction X between the two guide rails 24. The guide unit 20 moves the jig table 16 from the outside of the transferable region R of the transfer table 12 to the transfer table 12, and moves the jig table 16 between the transfer table 12 and the print head 13. Introduce. Here, the transportable region R refers to a region in which the transport table 12 can move by the operation of the printing apparatus 10. The guide unit 20 moves and introduces the jig table 16 from the outside of the transportable region R in which the transport table 12 can move to the transport table 12.

  Each of the pair of left and right guide rails 24 has rails 22 extending in the X direction on the inner surface. Casters 23 that roll on the rails 22 are attached to the four corners of the jig table 16. The jig tables 16 are guided by the guide rails 24 by rolling the right and left casters 23 on the rails 22 of the both guide rails 24.

  The urging unit 30 moves the jig table 16 guided by the guide unit 20 from the downstream side in the X direction toward the upstream side (in the X2 direction in the drawing), and moves outside the transportable region R. To the transportation platform 12. Then, the jig table 16 is urged in a state in which the jig table 16 is pressed against the pressing member 21 provided on the transfer table 12.

  In this example, the urging unit 30 includes a plastic chain 31, a chain cover 35, a gear 32, a shaft 33, a friction clutch 34, and a motor (not shown).

  The plastic chain 31 is connected to the jig table 16 and functions as a transmission member that transmits an urging driving force. The gear 32 applies a biasing force in the X2 direction to the plastic chain 31. The plastic chain 31 is covered with a chain cover 35 so that the urging force can be transmitted to the jig table 16 while maintaining a linear state even when the urging force is applied by the gear 32. A rotational driving force of a motor (not shown) is applied to the gear 32 by a shaft 33 and a friction clutch 34. As a result, an urging force in the X2 direction is applied to the jig table 16 via the plastic chain 31.

  The friction clutch 34 is a clutch that transmits rotation with frictional force up to a predetermined torque, but when the predetermined torque is exceeded, slipping and slipping prevent the rotation from being transmitted. The torque at which the friction clutch 34 stops transmitting rotation is such that the jig table 16 does not move after the jig table 16 is pressed against the pressing member 21. In addition, the torque is set to be smaller than the torque when the carriage 12 moves by the operation of the printing apparatus 10.

  FIG. 4 is a diagram illustrating a state where the guide of the jig table 16 is released.

  The rail 22 is provided outside the transferable region R of the transfer table 12 and is not provided in the transferable region R. Thereby, the guide unit 20 guides the jig table 16 outside the transferable area R of the transfer table 12 and releases the guide of the jig table 16 in the transferable area R. It is configured.

5A and 5B are diagrams for explaining a state in which the jig plate 25 is placed on the jig table 16. FIG. 5A shows a state in which the jig plate 25 is removed from the jig table 16, and FIG. The jig plate 25 is placed on the work table 16.
FIG. 6 is a diagram illustrating the positioning mechanism.

  In this example, the jig plate 25 is placed on the jig table 16, and the printing object 11 is placed on the jig plate 25 for printing.

  The jig table 16 is provided with three positioning pins 26 </ b> A and 26 </ b> B for positioning the jig plate 25. One positioning pin 26A is arranged on the front side in the direction X2 in which the urging unit 30 urges the jig table 16, and two positioning pins 26B are arranged on the rear side.

  The jig plate 25 is a quadrangle having a size and shape substantially the same as the jig table 16. A positioning hole 27B corresponding to the two positioning pins 26B on the rear side of the jig table 16 and a positioning recess 27A corresponding to the front positioning pin 26A are provided. The front positioning pin 26A and the positioning recess 27A are fitted, and the rear positioning pin 26B and the positioning hole 27B are fitted, whereby the jig plate 25 is positioned on the jig table 16.

  The jig plate 25 has a pair of positioning recesses corresponding to the pair of pressing members 21 provided on the transport table 12 of the printing apparatus 10 at the front end in the X2 direction when placed on the jig table 16. 28 is provided.

  The pressing member 21 of the transport table 12 and the positioning recess 28 of the jig plate 25 are in the state where the jig table 16 is pressed against the pressing member 21 provided on the transport table 12. And functions as a positioning mechanism for positioning the jig table 16 in the second directions X and Y.

  The guide unit 20 and the urging unit 30 described above are arranged so as to be lifted and lowered by a lifting device 38 provided on the table 37. A height detection unit 39 is provided on the table 37 so as to straddle the upper part of the guide unit 20 in a gate shape. The height detection unit 39 and the lifting device 38 adjust the height position of the upper surface of the printing object 11 to be printed.

[Description of operation]
In such a configuration, printing on the printing object 11 is performed as follows.

  First, the jig plate 25 is placed on the jig table 16, and the printing object 11 is placed on the jig plate 25. At this time, the jig table 16 is positioned outside the transferable region R of the transfer table 12. Then, the jig table 16 is moved to a position where the printing object 11 is positioned below the height detection unit 39. In this state, the elevating device 38 is operated to raise and lower the guide unit 20. Thereby, the jig | tool table 16, the jig | tool board 25, and the printing target object 11 raise / lower. The height detection unit 39 detects the height position of the upper surface of the print object 11, and when the clearance with the print head 13 reaches an optimum height for printing, the lifting device 38 is stopped.

  Next, the urging unit 30 is operated, and the jig table 16 is moved in the X2 direction. That is, a motor (not shown) is rotated, and the rotation is transmitted to the plastic chain 31 via the friction clutch 34, the shaft 33 and the gear 32. As the plastic chain 31 moves forward in the X2 direction, the jig table 16 moves in the X2 direction. At this time, when the jig table 16 is outside the transferable region R of the transfer table 12, the jig table 16 is guided by the casters 23 rolling on the surface of the rail 22. When the jig table 16 enters the transferable region R of the transfer table 12, the guide of the jig table 16 is released, and there is a slight backlash in the planar direction.

  When the jig table 16 further moves in the X2 direction in this state, the positioning recess 28 provided at the front end portion of the jig plate 25 is engaged with the pressing member 21 provided on the jig table 16, The position in the plane direction of the jig table 16 with play is determined. In this state, the jig table 16 is pressed against the pressing member 21 and no longer moves. At this time, the urging unit 30 continues to operate. In other words, the motor (not shown) continues to rotate, and when the torque exceeds a certain level, the friction clutch 34 idles. Thereby, a certain weak torque is transmitted to the shaft 33, the gear 32, and the plastic chain 31. This torque is set so weak that it does not move after the jig table 16 is pressed against the pressing member 21.

  In this state, the jig table 16, the jig plate 25, and the printing object 11 are disposed between the transport table 12 and the print head 13. At this time, the jig table 16, the jig plate 25, and the printing object 11 are in the transportable region R of the transport base 12.

  In this state, the printing apparatus 10 is operated. The carriage 12 starts moving in the X direction, and the print head 13 ejects ink downward while reciprocating in the Y direction. As the carriage 12 moves in the X direction, the jig table 16 pressed against the pressing member 21 moves backward. That is, the friction clutch 34 idles, the plastic chain 31 moves in the X direction, and the shaft 33 and the gear 32 rotate in the reverse direction. In other words, the urging force in the X2 direction by the urging unit 30 is set so as to be weaker than the force of the transport base 12 of the printing apparatus 10 moving in the X direction.

  Therefore, printing can be performed on the printing object 11 placed on the jig table 16 and the jig plate 25 by the same control as when the printing object 11 is directly placed on the transport table 12 for printing. It can be done.

[Function and effect]
