Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas (mainly LPG) container printing machine. Conventional gas container printing machines print with the gas container laid down horizontally and held between the top and bottom. Since printing cannot be performed until the containers are turned over one by one and re-snipped between the rollers, there is a problem in that the work efficiency is extremely low and a lot of time and labor is wasted. The present invention solves such problems and allows printing on gas containers that can be immediately hung vertically on a trolley conveyor without having to turn them over horizontally. It was invented for the purpose of providing a container printing machine.

The present invention will be explained below with reference to the drawings. 1 is a movable trolley with bearing movable wheels 2, 2 on the lower side and installed laterally, and is laid in a direction parallel to the traveling direction of a trolley conveyor (not shown). It is placed movably on the rail 3. Reference numeral 4 denotes a movable prime mover mounted and fixed on the movable truck 1, and a chain 7 is wound around the rotary shaft 5 of the movable prime mover and the wheel shaft 6 of the movable wheel 2 via a sprocket. 8, 8 is located on the left half (left half in Fig. 1) of the movable cart 1 in an approximately X-shape in the left-right direction (left-right direction in Fig. 1), and extends left and right around the pivot 9 inserted through the center. The ends are lift side rods installed in parallel so that they can be opened and closed up and down. Reference numeral 10 denotes a lift starting point where the inner lower end of the lift side rod 8 is pivotally connected to the movable cart 1. 11 is lift side rod 8
This is a moving shaft inserted through the lower end of the outer side of the movable cart 1 in parallel with the width direction (the front direction in FIG. 1) of the movable cart 1. Reference numerals 12 and 12 denote wheels rotatably mounted on both ends of the moving shaft 11. 13, 13 is the wheel 1
The wheels 12, 12 are laid on the movable dolly 1 so that they roll within the guide rails 13, which are guide rails provided at positions where the wheels 2 and 12 move inward and outward on the movable dolly 1. 1
4 pivots the inner upper end of the lift side rods 8, 8 15
This is a lift base plate provided horizontally above the lift side rod 8. Reference numeral 16 denotes an upper moving shaft that is inserted through the outer upper end of the lift side rod 8 in a direction parallel to the moving shaft 11. 17, 17 are wheels rotatably attached to both ends of the upper moving shaft 16. Guide rails 18, 18 are provided at positions where the wheels 17, 17 move inward and outward on the lower surface of the lift base plate 14, and are laid on the lower surface of the lift base plate 14 so that the wheels 17 roll within the guide rail 18. . 19, 19 is the lift base plate 14
These are guide rails installed parallel to each other in the left and right direction on the top.
Reference numeral 20 denotes a printing table that is loosely fitted into the guide rail 19 so as to slide in the left and right direction. Reference numeral 21 denotes a cylinder for sliding the printing table 20, and the outer body of the cylinder is fixed on the lift base plate 14 in the moving direction of the printing table 20 (left-right direction in FIG. 1). is pivotally connected to the printing table 20. 23, 23 is the printing table 20
Inside position (left and right center position side of moving trolley 1)
In addition, there is a tire roll rotating shaft which is longitudinally supported at positions slightly shifted forward and backward in the width direction from the center line in the width direction of the printing table 20. 24, 24...
is a tire roll that is attached to each tire roll rotation shaft 23 to rotate vertically and laterally. Reference numeral 25 denotes a plate cylinder provided to rotate laterally on the tire roll rotation shaft 23 at an intermediate position between the upper and lower tire rolls 24, 24. Reference numeral 26 denotes a prime mover which engages the tire roll rotation shafts 23, 23 via gears 27, 27, . Reference numerals 28, 28, . . . denote a group of inking rollers that are provided to rotate in parallel with the plate cylinder 25. 22, 29 are adjustment screws for the rollers 28, 28... 30 is a restraining side lift side rod formed symmetrically with the same structure as the lift side rod 8 and provided on the right half platform of the movable trolley 1, facing the lift side rod 8. Reference numeral 31 designates a restraint-side lift base plate provided laterally on the lift-side rod 30 in the same structure as the lift base plate 14 and symmetrically. Reference numerals 32 and 32 denote guide rails provided in two parallel rows in the left-right direction on the lift base plate 31 on the restraining side. Reference numeral 33 designates a restraining movement frame whose lower end is loosely fitted into the guide rail 32 so as to slide therein, and whose central portion is vertically vertically columnar. 34 is a cylinder for sliding the restraint movement frame 33, and the outer body of the cylinder is fixed on the lift base plate 31 in the sliding direction (left and right direction) of the restraint movement frame 33, and the tip of the telescopic shaft 35 of the cylinder 34 is restrained. It is pivotally attached to the moving frame 33. Reference numerals 36 and 36 designate pinch rollers provided vertically to rotate laterally around a restraining shaft 37 provided vertically inside the restraining movement frame 33 (center side in the left-right direction of the movable trolley 1). Reference numeral 37 denotes lift upper and lower rods which are mounted on the movable cart 1 to be rotated by bearing in the left and right longitudinal directions, and left and right moving shafts are provided at the lower end positions on the outside of each of the lift side rods 8, 8 and 30, 30. Screws 38, 38 are respectively carved in the parts where the shaft 11 moves (the left and right screws have opposite lead directions), and the vertically moving pieces 39, 3 are attached to the screws 38, 38 at the outer positions of each moving shaft 11, respectively.
9 are screwed together to move laterally. Reference numeral 40 indicates a lift for the lift upper and lower rods 37 provided on the movable cart 1, and a motor is used to engage the lift upper and lower rods 37 via a chain 41. Reference numeral 42 denotes a quick return cylinder of the movable trolley 1, which has a telescopic shaft pivoted to one side of the movable trolley 1 in the width direction. 43 is a phototube provided inside the restraining movement frame 33. 44 is a limit switch that comes into contact with a hook 45 of a trolley conveyor (not shown).

Because the present invention has such a configuration, the gas container A is transported by the trolley conveyor and the tire roll 2
4 and 24, the limit switch 44 and phototube 43 detect this, respectively, and capture the progress status of the gas container suspended on the trolley conveyor. The moving table 1 is moved to follow the progress of the gas container, and at the same time, the cylinders 21 and 34 are energized, the printing table 20 and the restraining movement frame 33 are moved inward, and the tire rolls 24, 24, etc. The pinch roller 36 holds the gas container A from the left and right sides, and then the prime mover 26 is rotated to rotate the tire roll 24 and the plate cylinder 25 via the gears 27.
5 can be attached and printed on the outer periphery of the gas container A. Also, in this case, it is necessary to change the printing position depending on the size of the gas container, but in this case, the lift motor 40 is rotated and the lift upper and lower rods 3
When 7 is rotated, the vertical moving piece 39 moves to the vertical rod 37.
The lift side rods 8 and 30 move up and down about the respective raft lifting starting points 10 in order to move the movement shafts 11 at the lower ends of each of the lift side rods 8 and 30 left and right. It can be moved and adjusted in the height direction. Also, to apply ink to the plate cylinder 25, the ink application rollers 28, 28 are connected to the plate cylinder 2.
By employing a known ink application method in which the ink roller 28 is attached and rotated, the plate barrel can be printed, and ink can be appropriately supplied from an ink supply device B provided near the inking roller 28. This allows continuous printing. Therefore, when the present invention is carried out, it is an invention that has the effect that it becomes possible to automatically print a predetermined mark at a predetermined position during the transport process of gas containers on a trolley conveyor.
