Abstract

PURPOSE:To uniformly supply ink over an entire type surface by reciprocating both or either one of a type holder and an ink roller in a state that the holder is oscillated at a position where a type can be brought into contact with the roller, reciprocating to bring the type into contact with the roller. CONSTITUTION:A type holder 12 is oscillated at about 90 degrees between a position for printing on a label and a position for supplying ink by the operation of a second air cylinder 10. An ink roller 24 is disposed through a post 22 secured on a stationary plate 4 near a flat surface 12d when the holder 12 is oscillated at an ink supplying position. A type held on the surface 12d of the holder 12 is brought into contact with the roller 24 to be reciprocated in contact therewith. As a result, ink is supplied to the surface of the type uniformly.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing device for printing on labels and the like.

[Conventional technology]

The lot number or manufacturing date is printed on the labels affixed to containers of alcoholic beverages, etc. Therefore, labelers (label packing machines) are usually equipped with a printing device. .

Conventional general printing devices have a type holder that holds type in two positions: one in contact with a printing object such as a label, and the other in a position where it retreats from that position and abuts an ink replenishing means such as an ink pad or ink roller. After printing is performed by pressing the type into contact with the label, it is swung to bring it into contact with an ink pad or the like to replenish ink to the type for the next printing.

[Problem to be solved by the invention]

In the conventional printing apparatus, ink may not be uniformly replenished over the entire printing surface, and in this case, there is a risk that printing may be incomplete, such as shading or blurring.

The present invention has been made to eliminate the above-mentioned drawbacks, and provides a printing device that can reliably replenish ink to printed characters.

[Means for Solving the Problems] A printing device according to the present invention includes a type holder that holds type, an ink roller that contacts the type and supplies ink, and a type holder that connects the type holder with the type when the type is in contact with the object to be printed. The type holder includes a swinging means for swinging between a position where printing is performed and a position where the ink roller can be contacted, and a reciprocating means for reciprocating at least one of the type holder and the ink roller.

[Function] In the printing device according to the present invention, while the type holder is swung to a position where the type can come into contact with the ink roller, both or either of the type holder and the ink roller are reciprocated, By bringing the type and the ink roller into reciprocating contact, the entire type surface can be evenly replenished with ink.

[Examples] The present invention will be explained below with reference to illustrated examples. 1 and 2 are a plan view and a side view of a printing device according to an embodiment of the present invention. In the figure, (2) is the fixed plate (4
), a support plate (8) is attached to the rod (6) of this air cylinder (2), and the support plate (8) reciprocates by the operation of the cylinder (2). .

The air cylinder (2) is attached to the lower surface of the support plate (8).
) A second air cylinder (lO) is installed parallel to the cylinder. The head of the second air cylinder (lO) is supported by the plate (8) via a ball joint (9), and an L-shaped type holder (
One end (12a) of the type holder (12) is connected, and the middle part (12b) of the type holder (12) is connected to the support plate (8).
It is supported by a shaft (14) fixed to and is rotatable. The other end (12) of the type holder (12)
Type is mounted on the flat surface (12d) of c).

By the operation of the second air cylinder (10), the type holder (12) is moved between the position shown by the solid line in FIG. Swings approximately 90 degrees. Type holder (1
A bottle (16) is fixed to a portion closer to the air cylinder (10) than the shaft (14) of the type holder (2), and when this bottle (16) hits a stopper (18) fixed to the support plate (8), the type holder ( 12) Stop the rocking.

An ink roller (24) is arranged near the flat surface (12d) when the type holder (12) swings to the ink replenishment position via a support (22) fixed on the fixed plate (4). ing. This ink roller (24) is connected to the support (22)
It can be attached and detached from the

In this embodiment, the printing device is installed in a linear labeler, and when the container conveyed on the conveyor (26) reaches the labeling station, the glue plate (28) swings and the glue is first applied. After the adhesive is applied to the surface by a roller (30), it adheres to the bottom label of the label magazine (32), takes it out, returns to the position of the container on the conveyor (26), and stops. At this time, the first air cylinder (2
) is activated and the support plate (8) is moved to the left side in the drawing. In addition, the rond of the second air cylinder (10) (
11) has been extended and the type holder (12) has swung to the position shown by the two-dot chain line in FIG. From this state, the second air cylinder (10) is activated to swing the type holder (12) to the position shown by the solid line in FIG. 1, thereby printing on the label held on the glue plate (28).

When printing is completed, the second air cylinder (lO) is operated to swing the type holder (12) again to the position indicated by the two-dot chain line.

Next, the first air cylinder (2) is reciprocated to reciprocate the support plate (8). The type holder (12) is attached to the support plate (8), while the ink roller (
24) is fixed to the fixed plate (4), so the type held on the flat surface (, 12d) of the type holder (12) contacts the ink roller (24) and reciprocates while rotating it. . As a result, ink is evenly replenished onto the surface of the typeface.

In this way, when replenishing ink to the printed characters, the contact between the two is made twice, once back and forth, so there is no risk of incomplete printing due to insufficient ink supply. Also, when the ink roller (24) runs out of ink, the ink roller (24)
24) from the support column (22) and replace it.

In the above embodiment, the printing device is installed in the label pasting station of the labeler, but it goes without saying that it can be used for other purposes as well. Further, the ink roller (24) may be moved back and forth along the type holder (12).

(Effects of the Invention) As described above, according to the present invention, ink is supplied by bringing the type holder and the ink roller into reciprocating contact, so there is no risk of ink supply failure and incomplete printing. There is no.
