Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a manual labeler that can accurately adjust the position of a label relative to a printing device.

<Prior Art> This type of labeler has the disadvantage that the label tape is loaded manually, and the printing position on the label changes due to errors that occur during loading.

For this reason, even in the past, for example,
A label position adjustment mechanism as disclosed in Japanese Patent No. 136200 has been proposed.

<Problems to be Solved by the Invention> However, the adjustment mechanism disclosed in the above-mentioned publication is
As shown in FIGS. 4 and 15, the label tape is divided into a feed wheel 69 for transporting the tape and a ratchet wheel 133, and clutch members 145 and 147 connecting the two are connected to the slot 1.
By inserting a coin into the wheel 51 and applying an inward force, the coin can be separated and the relative position of the feed wheel 69 and the ratchet wheel 133 can be selected. In addition to the inconvenience of having to perform the adjustment within a narrow labeler case, there is also the problem that the structure of the adjustment mechanism is complicated and the manufacturing cost is high.

<Means for Solving the Problems> In the labeler of the present invention, the label position can be adjusted by simply moving the knob 325 from the outside of the case 1.

For this purpose, the adjustment means 32 of the labeler according to the invention
The rack gear 31 meshing with the one-way clutch 41 on the feed drum 42 side is vertically displaced by manual operation from the outside, thereby adjusting the position of the label 82 on the label tape 8. There is.

The adjustment means 32 forms a shaft hole in the upper part of the rack gear 31, tightly fits the rotor 321 into the shaft hole, and inserts the rotor 321 into the rotating frame 2 of the operating mechanism 2.
The rotor 321 has a spring 323 which is eccentrically pivotally connected to the rotor 2 by a support shaft 322, and which biases the rotor 321 so as to constantly press it against the rack gear 31.
and an engaging portion 324 that engages the rotor 321 with the rack gear 31 when the rotor 321 is biased by the
The rotor 321 is provided with a knob 325 for retracting the rotor 321 against the spring 323 and thereby disengaging the rack gear 31 from the rotor 321.

<Function> Since the labeler of the present invention is as described above, the knob 325 is operated to disengage the rotor 321 from the rack gear 31 in a state in which the rotor 321 is in close contact with the rack gear 31, and then the rotor 321 is disengaged from the rack gear 31 by operating the knob 325. 321
When rotated, the eccentric rotation of the rotor 321 about the support shaft 222 causes the rack gear 31 to displace its position in the rotating frame 22 by a minute amount in the vertical direction.

When the rack gear 31 moves upward, the one-way clutch 41 is connected to the feed drum 42 and rotates slightly, so that the label tape 8 is transferred by the rotation angle of the feed drum 42 and the label 82 is The position is finely adjusted.

On the other hand, when the rack gear 31 moves downward, the one-way clutch 41 rotates without being connected to the feed drum 42, so the label tape 8 remains stationary. One-way clutch 4 during upward movement of frame 22
Since the rotation of the label tape 8 decreases by a small angle, the feed length of the label tape 8 is shortened, and the label 8
The position of 2 is adjusted so that it is moved relatively backward.

<Example> The labeler of the present invention will be explained below with reference to the accompanying drawings. In Fig. 1, 1 is a case, 2 is an operating mechanism, 3 is a feed drive mechanism, 4 is a transfer device, 5 is a printing device, and 6 is an ink application device. 7 is a peeling mechanism, and 8 is a label tape.

The above case 1 is a holding part 11 for the label tape 8.
It has a main part 12 that houses the transfer device 4, printing device 5, etc., and a grip part 13 extending from the main part 12.

As shown in FIG. 4, the holding section 11 is constructed to hold the label tape 8 wound in a roll between a pair of elastic pieces 111, 111', and is attached to the dial side of the printing device 5, which will be described later. A protruding piece 112 is provided that protrudes outward from the dial, and as shown in FIG. 1, by fitting and fixing the elastic pieces 111, 111' to the case main part 12, the label tape 8 can be removed. It is possible to maintain it.

The grip part 13 has an inner chamber 131 facing downward in the figure.
is open, and the lever 21 of the actuation mechanism 2 is disposed opposite this inner chamber 131.

The operating mechanism 2 includes a lever 21 whose inner end is pivotally supported by the main part 12 and whose outer free end rotates toward and away from the grip part 13, and a rotating frame 22 connected to the inside of the lever 21. The lever 21 and the rotating frame 22 are pivotally connected to the main part 12 by the same pivot 23, and the lever 21 and the rotating frame 22 are always connected by a return spring 24 mounted between the rotating frame 22 and the grip part 13. The lever 21 is biased so as to be separated from the grip 13.

In order to obtain cooperation between the lever 21 and the rotating frame 22, the lever 21 and the rotating frame 22 may be made integrally, but in this embodiment, the lever 21 is attached to the 211
The rotating frame 22 is supported by the rotating frame 211 for the time being, and the rotating frame 22 is provided with a support shaft 221, and the end of the spring 24 is connected to this supporting shaft 221, whereby the rotating frame 22 is supported for the time being. 211 is configured to be pressed.

As shown in FIGS. 5 and 6, the feed drive mechanism 3 includes a rack gear 31 rotatably provided on the rotating frame 22, and an adjusting means 32 for adjusting the position of the rack gear 31. , the position of the rack gear 31 in the rotation frame 22 is configured to be able to be displaced in the width direction of the rotation frame 22, that is, in the vertical direction in the figure, by the rotation of a rotor 321 provided on the rack gear 31. .

The mechanism shown in the embodiment as the adjustment means 32 is such that the rotor 3 is inserted into the shaft hole formed in the rack gear 31.
21, and the eccentric position of this rotor 321 is pivotally connected to the rotating frame 22 by a support shaft 322, and the rotor 321 is provided with a spring 323 that constantly presses the rotor 321 against the rack gear 31. The rack gear 31 is provided with a locking portion, for example, a locking pawl 324, for locking the rack gear 31. In order to engage the locking pawl 324, the rack gear 31 is provided with a plate surface 311 on its pivot side. A large number of engagement holes 312 are formed in this plate surface 311 .

In the above embodiment, the rotor 321 can be moved to the spring 3 by gripping the knob 325 provided on the rotor 321.
23, the rotor 321 is brought into close contact with the rack gear 31, and the rack gear 31 is released from the locking part, and then the rotor 321 is rotated. It is displaced as the rotor 321 rotates eccentrically, and is fixed at the displaced position when the rotor 321 engages with the rack gear 31 again.

The amount of movement of the rack gear 31 is the amount of movement of the rotor 321.
However, since the label position adjustment dimension is extremely small, it is usually sufficient for the rotor 321 to have a small diameter.

That is, since the above-mentioned rack gear 31 meshes with a passive gear 411 of this clutch 41 to drive the one-way clutch 41 of the above-mentioned transfer device 4, when the rack gear 31 is moved in the vertical direction in the figure, the movement of this rack gear 31 is As a result, the passive gear 411 rotates slightly, and by the upward movement of the rack gear 31, the label tape 8 is moved in the forward direction in a minute dimension and its position is adjusted.

In addition, in order to move the label tape 8 in the backward direction, it is sufficient to move the rack gear 31 downward in the figure in advance.
1, the label tape 8 does not immediately retreat, but when the label tape 8 moves forward next time, that is, when the lever 21 returns, the rotation of the passive gear 411 decreases by a minute angle, and the position of the label tape 8 is moved relative to the other. Adjust so that it moves backwards.

Therefore, the position of the label tape 8 with respect to the printing device 5 can be adjusted independently by operating the adjusting means 32, regardless of the vertical movement of the rotating frame 22 by the lever 21 of the operating mechanism 2.

Therefore, in the labeler of the present invention, when attaching the label tape 8, first the adjustment means 32 is
It is desirable to normally set the knob 325 at the center position, so that the position of the label 82 of the label tape 8 can be freely adjusted in both the front and rear directions.

The other frame plate 521' has a receiving part 524 recessed above it so as to face the insertion hole 522, and the lower part of this receiving part 524 is provided with the frame plate 521'.
A receiving piece 525 for receiving the rotary disk is provided that extends toward.

Further, an appropriate number of connecting shafts 526 are horizontally suspended between the frame plates 521, 521', thereby fixing the pair of frame plates 521, 521' in a facing manner.

Between the pair of frame plates 521 and 521', a receiving mechanism 53 for receiving the printing belt is provided for each printing mechanism, and this receiving mechanism 53 is connected to a rotary receiving piece provided below the protruding base 531. 532 and this rotating piece 5

2 and the press rod 533 from other rotary receiving pieces 532 and the press rod 533; a support case 535 for receiving the press rod 533;
33, and a support shaft 537 on which the rotary receiving piece 532 is mounted on the support case 535 and whose both ends protrude from the support case.
To support this support shaft 537, for example, a vertically elongated bearing hole 538 provided at the lower end of the frame plates 521, 521', and a vertically long bearing hole 538 interposed between the protruding table 531 and the support case 535, It is provided with a fulcrum member 539 abutting on the central top, for example a block member made of an elastic material, and the rotary receivers 532 are aligned in the same number as the printing belts 54.

The protruding base 531 is usually the frame plate 521, 5
21', and in the embodiment, the half base portions that protrude from the inner walls of the pair of frame plates 521, 521' in opposing directions are joined when the frame plates 521, 521' are assembled. It consists of

The rotation receiving pieces 532 are arranged in a row corresponding to the printing belt groups so that each printing belt 54 can be attached to the respective printing belts, and are separated by spacers 534 so that they can rotate independently.

When pushed up by the elastic member 536, it is configured to retreat into the support case 535 against the pressing force of the elastic member 536.

The support case 535 is supported at the center of the top by the fulcrum member 539, and on both sides of the lower end by the vertically elongated bearing hole 538, and under normal conditions, the support shaft 537 is located inside the bearing hole 538 in the drawing. It is set to lock onto the bottom edge of the hole.

Therefore, in this catch mechanism 53, since both ends of the support case 535 can swing up and down by the length of the bearing hole 538 using the fulcrum member 539 as a fulcrum, the printing of the printing belt group on the surface of the label 82 is prevented. Even if the surface is slanted, this mismatch is absorbed by the swinging of the support case 535 during printing, and the printing surface formed by the printing belt group can be accurately brought into close contact with the label 82.

In the above, the support case 535 may be made to swing by other configurations, for example, a vertical groove is formed on the side surface of the support case 535 that is in contact with the frame plates 521, 521', and the groove is formed in the groove. A guide pin may be inserted from the frame plate side, or the fulcrum member 539 may be formed integrally projecting from the top of the support case 535.

A printing belt drive mechanism 55 is provided in the receiving portion 524 of the frame plate 521', and this drive mechanism 55
includes a locking piece 551 that is fitted into the receiving portion 524 and has a wavy locking surface 551' extending parallel to the protruding base 531; a stator 552 that fixes the printing belt 54 in the receiving portion 524, and a spacer 5 that separates the printing belt 54 from the frame plates 521, 521'.
53, 553', rotary discs 554 arranged in the same number as the number of printing belts so that the printing belts 54 can be respectively attached thereto, rotatably supporting the rotary discs 554 and having shaft ends protruding from the insertion holes 522. A rotary knob 556 is inserted between the selector shaft 555 and the rotary knob 556 to allow the selector shaft 555 to reciprocate in the axial direction. and an indicator 557 inserted into the mounting frame 52 from the insertion opening 523 parallel to the selector shaft 555;
5 and an engagement rod 558 provided in the inside.

The selector shaft 555 has a locking protrusion 555' at its tip, and is designed to engage the rotary disk 554 in the rotational direction by the locking protrusion 555'.

For this purpose, a through hole is provided in the center of the rotary disk 554 through which the selector shaft 555 is inserted, and
A locking groove 554' is formed in the wall of this through hole.

The printing belt 54 has a large number of printing marks 54.
For example, numbers, symbols, barcodes, etc. and corresponding readable characters 543 are formed in sequence,
By reading the read characters 543 with the indicator 557, it is possible to know the print arrangement forming the printing surface of the printing mechanism 51, that is, the arrangement of the print marks 541' on the lower surface of the rotary receiver 532.

Furthermore, the engaging rod 558 is connected to the selector shaft 5.
It is fixedly installed in a hollow chamber provided in 55.

The hollow chamber of this selector shaft is as shown in Fig. 7.

While being rotated, it makes its own swinging motion and comes into contact with the label receiving surface S of the peeling mechanism 7.

The printing mechanisms 51, 51' do not necessarily have to be constructed as in the embodiment, and for example, porous type that retains ink inside may be used.

In this case, since the printing itself becomes a so-called stamp type in which ink is self-supplied, the ink applicator 6 becomes unnecessary.

The ink application device 6 applies ink to the printed characters located on the lower surface of the printing device 5, and includes an ink roller 61 impregnated with ink, and this ink roller 61 is attached to one end, and the other end is attached to the ink roller 61 impregnated with ink.

It is constructed so that it can be pulled out of the case 1 at any time.

That is, this has the advantage that the ink roller 61 can be easily replaced and the inside of the case can be inspected easily.

When the printing device 5 descends, this ink roller 61 is pressed by it and retreats, but on the other hand, the printing device 5
When it rises, it returns by the force of the springing means 63, which is similar to the conventional device, but in this embodiment,
Since the printing device 5 swings in the opposite direction to the rotational direction of the ink roller 61, this movement and the rotational movement of the ink roller 61 combine to cause the relative sliding of the ink roller 61 with respect to the printing device 5. The rubbing stroke becomes large, and therefore, even if multiple printing mechanisms are installed as in the embodiment, all the printing mechanisms 51, 5
There is an advantage that the print 541' of 1' can be rubbed.

In the embodiment, this ink application device 6 includes a cover plate 6
The cover plate 64' is provided with a protrusion 641 that faces the protrusion 112 of the holding portion 11, and the printing device 5 is provided between the pair of protrusions 112 and 641. By locating the knob 556, it is possible to prevent the knob 556 from colliding with an external object and being damaged.

As shown in FIG. 2, the peeling mechanism 7 includes a receiving frame 71 that can rotate outward, a pressing member 72 that faces the receiving frame 71, and further guides the label tape 8 to the label receiving surface S of the receiving frame 71.

11 are provided.

Furthermore, this receiving frame 71 has supporting tongue pieces 712 and 71 that support the label 82 peeled off from the transfer tape 81.
2', guides 713, 713' that restrict movement of the label tape 8 in the width direction, and the guide frame 7.
The supporting tongues 712, 712' support the center portion of the lower surface of the label 82, and the supporting tongues 714, 714' By being locked by the guide frame 73, the receiving frame 71 is fixed in the case 1 as shown in FIG.
1 is configured to be able to rotate outward as shown by the chain line in FIG.

As shown in FIG. 2, the pressing member 72 includes a label pressing roller 721 and a pressing portion 722 extending above the receiving frame 71.

This pressing portion 722 presses the label 82 peeled off from the transfer tape 81 from its upper surface.
2' prevents the label 82 from falling off.

That is, the label 82 peeled off from the transfer tape 81
is connected to the next label only by the adhesive layer on its underside, this label 82 simply attaches its underside to the supporting tongue 7.
12, 712' is unstable, but if the upper surface is also pressed by the pusher 722 as in this embodiment, rotation in the counterclockwise direction is prevented as shown in FIG. This is because it can be held without falling off.

The label receiving surface S of the receiving frame 71 is made of an elastic sheet member 715, and this sheet member 715 is attached to the receiving frame 71 as shown in FIG.
It is removably fitted into a concave portion 716 formed on the top surface of the label, and the label receiving surface S is made smooth and the back surface is made into a deformable surface 717.

This back deformable surface 717 is made so that the label receiving surface S can be deformed in response to each printed character 541' that makes up the printing arrangement of the printing mechanism 51, and since there are two printing mechanisms in the embodiment, this etc. printing mechanism 51,
Two deformable surfaces 717 and 717' are formed on the sheet member 715 so as to correspond to each of the deformable surfaces 717 and 717'.

As shown in FIG. 13, this deformable surface 717 may be formed by continuously forming wave-shaped protrusions 718' on the back surface of the sheet member 715 so as to match the portions of the label surface S that are pressed against each other by the printed characters 541'. However, in the embodiment shown in FIG. 11, as shown in FIG.
41' is provided with protrusions 718 that receive the pressing force of each print 541' so that the protrusions 718 are aligned on the back surface of the label receiving surface S.

This protrusion 718 has a conical tip, and when the printing surface of the printing mechanism 51 is pressed against the label 82 on the label receiving surface S, the pressing force of each printed character 541' making up this printing surface As shown by the chain lines in Figure 12, they are constructed so that they each change distortion independently.
Due to the deformation of each protrusion 718 and the other protrusions, the minute unevenness of the printed characters 541' forming the printing surface is absorbed, and beautiful and clear printing is applied to the label 82.

Since the present grave labeler is like this, when the lever 21 is turned toward the grip 13 and approached,
