Patent JP-S63199643-A (JP)
Title: Printing machine
Inventor: TAKEDA TAKEFUSA
IPC: B41F15/40
Filed: 1987-02-13
Abstract: PURPOSE:To reduce unsatisfactory printing, by a method wherein a vibration proofing member is provided between a holder block holding a squeegee and a holding member supporting the holder block, and exciters imparting vibration to the squeegee in printing is mounted on the holder block. CONSTITUTION:A linear-motion actuator vertically driving a member built in a holding member 7 is securely installed to a fixed board 2 with a nut 3a. Simultaneously when the fixed board 2 starts traveling horizontally leftwards by a driver, the actuator 1 acts to move downwards, and the tip edge of a squeegee 17 moves leftwards while pressing down a screen 23. At this time, first and second exciters 19a and 19b are actuated. By the squeegee 17 a paste 26 travels and reduces in viscosity. Additionally, the vibration of the first and second exciters 19a and 19b reduces the viscosity of the paste 26, thus making the paste 26 easy to move downwards with the bubbles in the paste 26 eliminated. As a result, the paste 26 is printed on a matter to be printed 24 through the pattern of the screen 23. In this manner, by imparting the vibration to the squeegee 17, printing unsatisfactoriness is remarkably reduced, and production loss can be improved away to a great extent.

Abstract: PURPOSE:To keep constant pressure and prevent a pipe line from being damaged by providing a drain oil passage with a check valve at the same time as drain oil from an oil-hydraulic motor and drain oil from respective oil-hydraulic driving gears are returned via the drain oil passage in common. CONSTITUTION:An equipment is composed so that drain oil from an oil- hydraulic motor M1 and drain oil from the respective oil-hydraulic driving gears of a back-hoe device may be returned to a tank T via a drain oil passage 35 in common. In its case, a check valve 36 is set for allowing oil to be discharged to the side of the tank T. When a swing base is swung to be driven and to be stopped, then low back pressure is generated on the drain oil upstream-side of the check valve 36, and flow resistance is loaded on drain oil from other valve blocks, and so the oil is sucked up into an oil circuit 37 via a suction check valve 33, and back-pressure is always kept constant. As a result, shock due to sudden stop is attenuated, and the damage of a pipe line can be suppressed.
