JP-A-8-183164 Japanese Patent Laid-Open No. 2001-62999

  The open type pad printing machine has a mechanism in which ink existing in an ink tray is poured into an adjacent printing plate and the printing plate is filled with ink by scraping off an excess with a blade. In the open type pad printing machine, since the ink tray is opened, an odor due to volatilization of the solvent contained in the ink existing in the ink tray has occurred.

  On the other hand, in the closed type pad printing machine, an ink pot having an open bottom surface is placed on a printing plate, and either one of the printing plate or the ink pot is moved horizontally to move the inside of the ink pot. The ink stored in is filled in the printing plate. That is, in the closed type pad printing machine, the ink pod is closed by the printing plate, so that the ink existing in the ink pot does not touch the outside air. Therefore, since the closed type pad printing machine can suppress the volatilization of the solvent contained in the ink, the generation of odor is reduced compared to the open type pad printing machine.

  However, even in the closed type pad printing machine, since the solvent is volatilized from the ink filled in the printing plate and the ink attached to the pad, the generation of odor is generated although the amount is small.

  The present invention has been completed in view of the above technical problem, and an object of the present invention is to provide a novel pad printer capable of improving the working environment.

  In the pad printing machine of the present invention that solves the technical problem, after the ink filled in the printing plate is attached to the pad, the pad is advanced toward the work installation table, and the ink attached to the pad is removed. A pad printing machine for transferring to a workpiece installed on the workpiece installation table, comprising a ventilator that forms an air flow from the workpiece installation table to the printing plate (hereinafter, It is called “Invention Printing Machine”).

  In the printing machine according to the present invention, it is preferable that the pair of wall members are arranged on both sides of the work setting table and the printing plate so as to sandwich the traveling direction of the pad.

  In the printing machine of the present invention, it is further preferable that the adsorption device is disposed downstream of the position where the printing plate exists in the air flow formed by the ventilation device.

  According to the present invention, the work environment can be improved.

For convenience of explanation, the side of the pad printing machine main body 2 where the workpiece mounting base 23 exists is referred to as the front (front), and the side where the ink tray 21 exists is referred to as the rear (rear).

  The ink tray 21 includes an ink reservoir 211 in which the ink I is stored, and a printing plate container 212 disposed adjacent to the front of the ink reservoir 211, and the printing plate 22 has a printing pattern groove 221. Is stored in the printing plate storage portion 212 in a state in which is directed upward.

  The workpiece setting table 23 is a holder for holding the workpiece W. The work setting table 23 is arranged in front of the ink tray 21.

  The pad 24 is attached to the tip of a rod R of a cylinder S that is attached to an advance / retreat apparatus (not shown) that moves back and forth in the upper space of the stamp plate 22 and the work setting table 23. The rod R of the cylinder S can be advanced and retracted along the vertical direction. That is, the pad 24 can be moved back and forth between the printing plate 22 and the work setting table 23 by driving the advance / retreat apparatus. Further, the pad 24 can be moved up and down toward the stamp plate 22 or the work setting table 23 by driving the cylinder S.

-Ventilator 3-
The ventilator 3 forms an air flow (air flow from the front to the rear) from the work installation base 23 toward the stamp 22. In the present embodiment, the ventilation device 3 includes a fan 31 disposed at a lower rear portion of the ink tray 21 and a duct 32 connected to the fan 31.

  The printer 1 of the present invention having the above-described configuration causes the ink I filled in the printing plate 22 to adhere to the pad 24, and then advances the pad 24 toward the work installation base 23. The adhered ink I is transferred to the work W installed on the work installation table 23.

  In the present embodiment, the ink I is filled into the printing plate 22 as shown in FIG. 3 by using the ink plate IP that can move back and forth with the ink I stored in the ink reservoir 211 of the ink tray 21. After coating on the surface of the printing plate 22, the excess is scraped off by a doctor blade DB that can move back and forth. As a result, the ink I is filled in the printing pattern groove 221 of the printing plate 22.

  Further, as shown in FIG. 4, the ink I adheres to the pad 24 by moving the pad 24 to the upper space of the printing plate 22 by driving the advance / retreat apparatus and then driving the cylinder S. This is done by lowering the pad 24 and bringing the pad 24 into contact with the printing plate 22. After the ink I is attached to the pad 24, the pad 24 is raised by driving the cylinder S.

  Further, as shown in FIG. 5, the ink I adhered to the pad 24 is transferred to the work W installed on the work setting table 23 by driving the advance / retreat device. Then, the pad 24 is lowered by driving the cylinder S, and the pad 24 is brought into contact with the workpiece W. After the ink I is transferred to the workpiece W, the pad 24 is raised by driving the cylinder S.

  In the printing machine 1 of the present invention, as shown in FIG. 6, during the execution of each step, the ventilation device 3 is operated to form an air flow from the work installation table 23 toward the stamp plate 22. To do. In the present embodiment, by rotating the fan 31 of the ventilation device 3, air is pushed toward the duct 32, thereby forming an air flow from the work installation base 23 toward the stamp plate 22.

  When an air flow from the work installation base 23 toward the printing plate 22 is formed, the solvent volatilized from the ink I stored in the ink reservoir 211 of the ink tray 21 rides back on the air flow. In the opposite direction, the air is finally discharged through the fan 31 and the duct 32.

  That is, according to the printing machine 1 of the present invention, since the solvent volatilized is not directed to the worker who performs work such as replacement of the workpiece W in front of the printing machine 1, the worker does not feel the odor caused by the solvent. As a result, the working environment is improved.

  In the present embodiment, an open type is used for the pad printer main body 2. However, the pad printer main body 2 is not limited to an open type, and may be a closed type. good.

  In the present embodiment, the ventilation device 3 includes the fan 31 and the duct 32. By rotating the fan 31, the air is pushed toward the duct 32. However, the ventilation device 3 may be configured to suck air from the downstream side of the duct 32, for example.
