Description

[Detailed description of the invention] This invention involves printing on a printing medium such as a label or price tag, and pasting the printed printing medium on a target object such as a product.
Alternatively, so-called label printing and pasting machines and price tag printing installations that can be installed are related to printing devices in machines, especially printing devices that can print multiple pieces of information such as product price, quantity, or manufacturing date in multiple stages. 1. This invention relates to a printing device in which the interval between the multi-stage printing can be arbitrarily adjusted.

This kind of conventionally known multi-stage printing device has a plurality of printing devices, each of which has a plurality of rows of rotatable type wheels or type bands arranged in parallel, and which is equipped with an appropriate type selection mechanism, and is integrated into a printing device frame. Furthermore, the printing device frame is fixed to a yoke that moves up and down as the hand lever is grasped and released.

However, in this multi-stage printing device, each printing device has a structure fixed at a fixed position, so
It was not possible to change the spacing between printed characters to the desired spacing.

Therefore, for example, in a label such as the one shown in Fig. 4, on which a partition line l that defines the position to be printed is preprinted, the partition line l and the printing may overlap as shown in Fig. 4. Even if the printout is very difficult to read due to storage, you can adjust the position of the type on the printer to
It was impossible to print properly.

The present invention was devised in view of the above-mentioned circumstances, and its purpose is to construct a structure in which each printing device arranged in multiple stages can be slid and fixed independently. Another object of the present invention is to provide a printing device in which the spacing between printed characters can be arbitrarily adjusted.

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 to 3 show one embodiment of the present invention, in which a yoke 3 is fixed to a hand lever 2 rotatably pivoted to a machine frame 1, 1' of a label printing and pasting machine. A printing device 4 is attached to .3'.

This printing device 4 is configured to be able to slide in the front and back directions of the label printing and pasting machine (in the front direction of arrow PQ), respectively.
Each of the printers consists of printing units 5a and 5b on the base, and a printing unit 6 which is detachably attached to the printing unit 5b at the rear and has a code plate type 7 at the lower end for displaying the product name, store name, etc. Consists of a separate printer.

As shown in FIG. 3, the printing devices 5a, 5b have a plurality of type wheels 9, 9, . ... are arranged in parallel so that they can each rotate independently.

That is, each type ring 9 supported by the support column 11 has type letters 12, 12, . 13, 13... are formed.

In the support column 11, blind holes 14, 14, the same number as the type wheels 9, 9, etc. are bored in one row in the axial direction, and each blind hole A steel ball 16 is disposed at 14 and is urged by a spring 15.

The steel ball 16 engages with the recess 13 on the inner peripheral surface of the type ring 9, thereby positioning the type ring 9.

In addition, index letters are formed on the outer peripheral surface of each index wheel 10, and a gear 17 having a larger diameter than the index wheel 10 is fixed to one side of each index wheel 10. 1
7 engages with the locking recesses 30, 30, . ring 10
rotate in the opposite direction.

Note that the index wheel 10 is attached to the frame plate 8, by means of screws 18 and 18'.
It is supported by a support shaft 19 installed between 8'.

Reference numeral 20 denotes a support shaft that is inserted through the center of the support column 11, and screw holes 21 and 21' are formed in both end faces of the support shaft.

Furthermore, thin plates 22 and 22' are interposed between the frame plates 8 and 8' and the type wheel 9 and index wheel 10.
, 22', frame plates 8, 8', and yokes 3, 3', respectively.
', 23' are inserted through the screws 23, 23', and the tips of the screws 23, 23' are screwed into the screw holes 21, 21' of the support shaft 20.

The holes drilled in the yokes 3 and 3' are elongated holes 39, 39, and 39 that are formed long in the front and rear directions of the label printing and pasting machine (in the front direction of arrow PQ in FIGS. 1 and 2).
', 39'.

24.24' and 25.25' are a pair of upper and lower guides protruding from the outer surfaces of the frame plates 8, 8';
A yoke 3.3' is located between 4 and 25 and between 24' and 25'.

Each yoke 3, 3' has an upper edge and a lower edge parallel to each other, and the upper guide 24, 24' is in sliding contact with the upper edge of the corresponding yoke 3, 3', and the lower guide 25. ,2
5' are in sliding contact with the lower edges of the corresponding yokes 3, 3'.

Hence the guides 24, 25, 24'. 25' C. Guide the printing devices 5 a and 5 b along the yoke 3.3' 7 so that they can slide in the front and back direction of the label printing and pasting machine (in the forward direction of arrow PQ in FIGS. 1 and 2). It looks like this.

Above the index wheels 10, 10, . . ., a type selection shaft 26 is rotatably attached to a rod 27.

The selection shaft 26 has anti-slip V-shaped protrusions 28, 28 formed on both ends of its circumferential surface, and the above-mentioned protrusions 28, 28 are formed in the center of the circumferential surface. Output ring 10 and gear 17
Locking recesses 29, 29, . After engaging the type selection shaft 26, if the type selection shaft 26 is rotated, the index wheel 1
0 and the type wheel 9 rotate in conjunction with each other, the desired type 12 can be positioned at the printing position, that is, at the lowest end of the type wheel 9.

A pair of arms 31.31' are rotatably attached to both ends of each of the rods 27, 27, and the lower ends of the arms 31.31' are connected to the thin plates 22.22'. It is pivotally connected to the upper end extension 32, 32'.

Next, in FIG. 1, 33a and 33b are ink rollers rotatably attached to one end of holders 34a and 34b;
The other end is rotatably and resiliently attached to a stay installed between the machine frames 1 and 1'.

Moreover, 35 is a roll-shaped label continuous body, and the machine frame 1,
It is rotatably held by an arm-shaped side plate 36 at the upper part of 1'.

Explain the action.

When the hand lever 2 is squeezed, the yokes 3, 3' are lowered to print the type 12.1 located at the lowest end of the printing units 5a, 5b.
2 pushes away the ink rollers 33a and 33b, and at that time, the ink roller 33a.

33 b coats the type 12, 12 and code plate type 7 with ink and descends to contact the label on the printing stand (not shown) to perform predetermined printing.

Then, when the hand lever 2 is released, the yoke 3.3'
At the same time, the printing devices 5a, 5b and 6 also rise and return to their original positions as shown in FIG.

At the same time, the printed unit label 37 is sent out below the adhesive member 38 by a feeding device (not shown), and becomes ready to be attached to an object such as a product.

In the above printing operation, the characters 12 of the printing devices 5a and 5b
．． If the position of unit label 37 is incorrect,
For example, as shown in Figure 4, the printing did not fit neatly into the printing field m, and the printing overlapped with the partition line l, making it extremely difficult to read, and sometimes leading to misreading.

In such a case, loosen the fixing screws 23, 23' of each printer 5a, 5b from the outside of the vertically long guide holes 40a, 40b drilled in the frame frames 1, 1', and then Printer 5a, 5b with yoke 3.3'? If you slide the printing devices 5a and 5b along the
．． The shaft of 23' slides in the front-rear direction within the range in which it can move within the elongated holes 39, 39' of the yokes 3, 3'.

Therefore, by stopping the printing units 5a and 5b at desired appropriate positions and tightening the fixing screws 23 and 23', the printing units 5a and 5b are fixed to the yoke 3 and 3', and the desired character position can be obtained. Can be done.

As explained above, in the printing device according to the present invention, a plurality of printing devices can be individually slid along the yoke and fixed, so that the interval between each printing in multi-stage printing can be adjusted. This makes it possible to always print easily legible characters on labels and price tags.

In particular, for labels etc. that have pre-printed fields,
This effect is significant.
