Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printing position adjustment mechanism of a label printing device that is capable of adjusting the printing position on the label when printing on the label that is successively temporarily attached on a mount. .

Generally, in a label printing device, there are many cases where it is desired to adjust the printing position on the label.

For example, when fine-tuning the printing position during the assembly process, when the printing position has changed due to long-term use, or when
A typical example is when the printing position is appropriately set according to the request of the consumer. Therefore, if the printing position on the label is adjusted by adjusting the movement of the printing device, transfer mechanism, etc., the structure will become extremely complicated in relation to the connecting parts such as the power transmission mechanism for printing and transfer. Put it away.

Furthermore, various considerations are required to prevent a decrease in printing accuracy due to adjustment of the printing position or to prevent uncertain transport. The present invention has been made in view of the above-mentioned circumstances, and by configuring a reversing peeling section that reverses the mount and peels off the label so as to be able to move and adjust it in the front and rear directions along the label transport direction, Another object of the present invention is to provide a printing position adjustment mechanism for a label printing device that can adjust the printing position on a label without affecting the transport mechanism.

Label printing devices include manual and electric types, and among these, there are various types such as tabletop type, portable type, and so-called hand labelers that print by rotating a hand lever. There is a model.

Although the printing position adjustment mechanism according to the present invention can be applied to any type of label printing device, in the embodiment, an example in which it is applied to a portable manual label printing device will be described.

Generally, the printing wheel 9 of the first digit is fed by one character every specified number of printing times, and the printing wheel 9 of the upper digit is fed with the printing wheel 9 of the lower digit.
By raising the carry, the number of characters is sent one character at a time. Main ink roller 8 and auxiliary ink roller 1
9 is connected to the actuating member 5 by a link mechanism (not shown).

Each of these ink rollers 8, 19 is connected to an operating grip 6.
When the printing device 10 descends with the printing operation, that is, the operation in the direction of the arrow A, the surface of each character 12 to be printed is transferred and ink is applied to reach the position shown by the dashed-dotted line. Then, when the printer 10 rises due to the action of the main spring 7, it returns to its original position as shown by the solid line while moving over the surface of each printed character 12 again. A holding section 21 that rotatably holds a wound elongated label band 20 is provided in a part of the main body 1. The label strip 20 consists of a strip-shaped mount 20a and a large number of labels 20b that are successively temporarily attached onto the mount 20a with a pressure-sensitive adhesive applied to the back surface. Label strip 2 held by the holding section 21
The paper is guided by the guide members 22 and 23 and reaches a reversal peeling part 42 formed at the front end of the label 20b of the guide plate 40 in the transport direction, which will be described in detail later, where only the mount 20a is reversed and guided backward. There is. Further, the guide member 22 includes:
The label 20 is placed from near the position where the characters 12 pass, at intervals that allow each character 12 to be printed by the printer 10 to pass through.

The transport mechanism 25 that transports the label 20b includes a transport roller 27 that is pivotally connected to the main body 1 through a shaft 26, and a lever 28 that transmits the operation of the operating section 5 to the transport roller 27.
It consists of

The lever 28 is attached to the main body 1 by a shaft 29, and one end is connected to the actuating section 5, and the other end is connected to the transfer roller 27. The transfer roller 27, to which the operation of the actuating section 5 is transmitted by the lever 28, is rotated by a predetermined angle in the direction of the rebound indicator in FIG. 1 by the action of a built-in one-way clutch (not shown). With this rotation, the feed dog 27a formed on the outer periphery engages with a transfer hole (not shown) of the backing paper 20a and pulls the backing paper 20a, thereby causing the label 20b
It is configured to transfer one sheet at a time.

A bottom cover 31 is provided below the main body 1, and one end of the bottom cover 31 is pivotally attached to the main body 1 through a shaft 3 so that it can be opened and closed.

As shown in FIG. 2, the bottom cover 31 consists of a pair of holding members 32 provided in parallel to each other on both sides, and a connecting portion 33 that connects the holding members 32 near the pivot portion. The connecting portion 33 is formed with a groove 33a through which the feed dog 27a passes. A recess 32a is formed on the outer side of the tip of each holding portion village 32, and these recesses 32
When the bottom cover 31 is closed, elastic protrusions (not shown) provided inside the side plates 37 of the main body 1 are respectively engaged in the insides a.

Each holding member 32 is formed with a hole 32b that penetrates from the inside to the outside.

These holes 32b are long in the longitudinal direction of each holding member 32 and have a diameter that allows the screw 34 to be inserted easily. Furthermore, a protrusion 35 extending in the longitudinal direction is integrally provided on the front inner side of the outermost hole 32b of each holding portion village 32. The bottom cover 31 holds the guide plate 40 by a protrusion 35 provided on a pair of holding members 32 and a screw 34 inserted through the hole 32b. The guide 40 is a part that guides the label strip 20, and includes a flat platen 41 provided in the center portion and the label 20.
b An acute-angled reversal peeling section 42 provided at the front end in the transport direction
and mounting portions 43, which are provided on both sides and are slightly thicker than the platen 41 portion, are integrally formed. A groove 43a is formed on the outside of each attachment portion 43 from approximately the middle toward the front end, and these grooves 43a include
As shown in FIG. 3, the corresponding protrusions 35 are fitted together to the extent that they can be slid together. Further, a screw hole 43b is formed behind each groove 43a, and each screw hole 43b has
A screw 34 inserted into the outermost hole 32b of each holding member 32 from the outside is screwed together to fix the guide plate 40 to the bottom cover 31.
The label band 20 is guided while being restricted from moving laterally by a guide step 44 formed at the boundary between the platen 41 and both attachment parts 43.

Then, only the mount 20a is reversed at the reversing and peeling section and guided backward, that is, in the direction of the transfer roller 27 in FIG.
The label 20b is peeled off from the mount 20a at this inversion peeling section 42. In FIG. 1, reference numeral 45 denotes a temporary holding piece that is integrally provided inside the side plates 37, and temporarily holds the peeled label 20b together with the pair of label guide pieces 22a so that it does not fall downward. do.

The temporarily held label 20b is moved by the rotating piece 51 and the striking member 5.
2, and a pasting member 53, the pasting mechanism 50 is pasted onto an object 56. That is, the actuating member 5
When the actuating member 5 is raised, the rotary piece 51 pivotally attached to the actuating member 5 engages with the locking step 52a of the striking member 52, and the striking member 52 is dragged upward. And, the rotating piece 51 is
Due to the action of the cam surface 54 formed on the main body 1, it rotates clockwise in FIG.
As a result, the pasting member 53 instantly rotates around the shaft 55, and presses and pastes the temporarily held label 20b onto the object 56 to be pasted. Next, the operation of the printing device having the above configuration will be explained.

First, when the operating grip 6 is pushed down in the direction of arrow A, the main shaft 4 and the actuating member 5 are lowered.

As the actuating member 5 is lowered, the printing device 10 is lowered, and the main ink roller 18 and the auxiliary ink roller 19 move over the surface of the type 12 to be printed and apply ink. Then, the printing device 10 further descends and presses against the label 20b located on the platen 41, thereby printing on the label 20b. Next, when the grip 6 is released, the action of the main spring 7 causes the grip 6, main shaft 4,
As the actuating member 5 and the printer 10 rise in the direction of arrow B in FIG.
In the figure, the mount 20a is rotated counterclockwise by a predetermined angle and the mount 20a is pulled, and the label 20b is transferred by one sheet. Therefore, after the printed label 20b is peeled off by the reverse peeling section 17a, it is temporarily held by the tip of the guide plate 22 and the temporary holding piece 32. Then, the label 20b temporarily held by the pasting mechanism 50 is pasted onto the object 56 to be pasted. Thereafter, the actuating member 5 comes into contact with the inner surface la of the upper plate of the main body 1, and printing, transporting, and pasting of one label 20b are completed.
Therefore, in order to adjust the printing position on the label 20b, after loosening each screw 34, move the guide plate 40 along the protrusion 35 to move the reverse peeling part 42 in the front and back direction, and then tighten each screw again. Tighten 34.

For example, as shown in FIG. 4, when the reversing and peeling section 42 is moved forward in the transport direction of the label 20b by an amount L together with the guide plate 40, the label 20b is moved forward by the amount of peeling.

That is, the mount 20a is attached to the feed tooth 27a of the transfer roller 27.
Since the reverse side is fixed by
This is because only the sum of the pre-inversion portion L and the post-inversion portion L of the mount 20a, that is, the hole, is fed out forward from the holding portion 21. The printing device 10 that prints on this label 20b is
Since there is no change in the transport direction of the label 20b, the subsequent printing position on the label 20b changes backward. Also,
If the reversing peeling section 42 is moved backward in the transport direction of the label 20b, the printing position on the label 20b will be changed to the position of the reversing peeling section 42.
changes forward by twice the distance traveled.

In the above embodiment, the reversing peeling section 42 is shown as being integrally constructed with the platen 41, but the platen 41 is fixed to the bottom lid 31 and only the reversing peeling section 42 is movable and adjustable with respect to the bottom lid 31. It can also be configured to do so.

In addition, in order to facilitate label loading, the platen 41
Although the reversing peeling portion 42 is provided on the bottom cover 31 which can be opened and closed, these may be provided directly on the side plate 37 of the main body 1 or the like.

Furthermore, as a guide and fixing structure for the inversion peeling section 42,
Although the configuration using the protrusion 35 and the screw 34 is illustrated,
These may have other configurations, and in short, the inversion peeling portion 42
It suffices that the structure is such that it can be moved and adjusted in the transport direction of the label 20b and is fixed after adjustment.

As described above, the present invention is configured such that the reversing peeling section can be moved and adjusted in the front and rear directions along the label transport direction, so that printing on the label can be performed without adversely affecting the printing device and the transport mechanism. The position can be easily adjusted.
