Abstract

PURPOSE:To contrive the simplification of production lines in a plant and the improvement of the degree of freedom for users to select function by providing a means for detecting the presence or absence of a label, a backing paper guide means and a rewinder unit based on the selective use of a backing paper guide. CONSTITUTION:A housing 1 is provided with a means 27 for detecting the presence or absence of a label, a backing paper guide means 28 and a rewinding unit 29 in order to obtain an operative condition, whereby the printed backing paper 3 of the label 2 is wound around a take-up shaft 41 of the rewinder unit 29. Therefore, the printing position of the label 2 is regulated by a platen 11 for moving the backing paper and the backing paper 3 is bent by a tensile force based on the driving force delivered from the rewinding unit 29 to facilitate the separation of the label 2 therefrom. This method can provide a standard machine with additional functions and contrive the simplification of production lines in a plant and the improvement of the degree of freedom for users to select the function.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a label printing machine that prints necessary information on a label attached to a long mount and issues the label.

2. Description of the Related Art An example of a conventional label issuing machine will be described with reference to FIG. First, a label roll holding section 5 is formed in the upper part of the housing 1 to hold a label roll 4 wound around a long backing paper 3 on which labels 2 of a certain size are stuck at equal intervals. There is. This label roll holding section 5 includes a vertically erected support 6 and a horizontal holding shaft 7 which is fixed to the upper part of this support and has a diameter much smaller than the inner diameter of the label roll 4.
and a clip 8 attached to the end of the holding shaft 7.

Next, inside the housing 1, a substantially U-shaped bell introduction guide 9 is provided. A platen 11 and a thermal head 12 constituting a printing mechanism 10 are provided at the tip of the label introduction guide 9. The platen 11
is connected to a drive section (not shown), and the thermal head 12 is pressed against the platen 11. Furthermore, an ink ribbon mechanism 13 is attached to the upper part of the label introduction guide 9. This ink ribbon mechanism 13
consists of a ribbon roll 15 that holds the ink ribbon 14, a plurality of ribbon guide rollers 16, and a ribbon take-up shaft 17.

Furthermore, a peeling plate 18 that sharply bends the mount 3 is provided at the tip of the platen 11.

A label issuing port 19 is formed at the tip of the peeling plate 18, and a label sensor 20 is provided above the label issuing port 19 as means for detecting the presence or absence of a label.

Next, below the peeling plate 18, a pinch roller 21 connected to a drive section and a pinch presser roller 22 pressed against the pinch roller 21 are provided.

Two guide rollers 23 are provided below the label introduction guide 9. Furthermore, the housing 1
A winder 24 is fixedly provided on the back surface of the winder 24, which is connected to a drive section.

In such a configuration, printing on the label 2 is performed by driving the platen 11 to control the amount of movement of the label 2, and by energizing the thermal head 12 to print necessary information. Further, the backing paper 3 is pulled by the driving of the pinch roller 21, and the backing paper 3 is sharply bent at the peeling plate 18, and the label 2 is peeled off from the backing paper 3 and the label issuing port 1
Published from 9. And the mount 3 is a guide roller 23
After that, it is wound up by a rewinder 24.

Thus, label issuing stops when most of the label 2 is peeled off and a portion of the rear end is attached to the mount 3. In this issuing state, the label sensor 20 is detecting the label 2, and as long as this detection signal is present, the next label 2 will not be issued.

Then, by removing the issued label 2 by hand, the next label can be issued.

Problems to be Solved by the Invention This type of label printing machine can be used in a variety of ways, as described below.

(1) The label 2 is peeled off from the backing paper 3 and issued, and the backing paper 3 is wound up with the rewinder 24.

(2) The label 2 is peeled off from the mount 3 and issued, and the mount 3 is discarded by dripping.

(3) The printed label 2 is wound up with the rewinder 24 while being attached to the mount 3.

When the printed label 2 is wound up with the winder 24 while attached to the mount 3, a gently curved mount guide (not shown) is used to prevent the mount from bending sharply at the peeling plate 18. use

These usages can be roughly divided into: ◎When the backing paper 3 is wound up by the rewinder 24, regardless of whether the label 2 is to be peeled off from the backing paper 3.

◎When mount 3 is dripped.

It can be classified into two types. Therefore, when winding up the mount 3 with the rewinder 24, as described above,
Mechanical components such as a label sensor 20, a liner tensioning mechanism using a pinch roller 21, a guide roller 23, and a rewinder 24 are required. On the other hand, when the mount 3 is dripped, the above-mentioned mechanical parts are not required.

For this reason, conventionally, an expensive machine exclusively for winding the liner, which is equipped with all of the above-mentioned mechanical parts, and an inexpensive machine, only for dripping, which omit the above-mentioned mechanical parts, have been manufactured separately.

Therefore, two models have to be manufactured from the beginning on the production line, which poses the problem of difficult management. Furthermore, there is a problem on the user side as well, in that if it is necessary to change the usage condition, the user must purchase a different type of device.

Means for Solving the Problems The present invention includes a label roll wound with a long backing paper to which a label is attached, a printing mechanism for printing on the label, a release plate that sharply bends the backing paper, and a release plate adjacent to the release plate. a labeling machine having a built-in guide roller that determines the bending angle of the mount; a label presence/absence detection means that is detachably attached to a label issuing port adjacent to the peeling plate; A mount guide that is attached to gently bend the mount; a mount guide that is selectively attached to the standard machine and determines a path for the mount together with the guide roller; a drive section; and a winding driven by the drive section. The rewinder unit is equipped with a shaft and is detachably attached to the standard machine.

The guide rollers provided in the standard machine are not necessary when using the mount with a dripping effect, but the standard machine can be used as is without any additional parts attached, and the mount can be used as is. When winding up the label, select the use of a mount guide depending on whether or not you want to peel off the label.
By attaching a label presence/absence detection means, a mount guide means, and a rewinder unit, it is possible to add other functions to the standard machine, simplifying the production line at the factory and increasing the flexibility of the user's function selection. The structure is such that it is possible to improve the performance.

Embodiment An embodiment of the present invention will be explained based on FIGS. 1 to 8. Components that are the same as those described with reference to FIG. 9 are designated by the same reference numerals, and description thereof will be omitted. First, this embodiment has a standard machine 25, which is shown in FIG. − number of guide rollers 26 are provided at the portion.

A mechanical component that should be attached to the standard machine 25 formed in this way according to its use is the label presence/absence detection means 27.
, a mount guide means 28 , a rewinder unit 29 ,
Four types of mount guides 30 are prepared.

First, the label presence/absence detection means 27 detects the label sensor 3.
1, this label sensor 31 is attached to a prismatic sensor support fitting 34 attached to the side surface of the housing 1 via a mounting nut 32 and a spring washer 33, so that its position can be freely adjusted. There is. A connector 35 is pulled out from the label sensor 31.

Next, the front three-piece scarecrow stage 28 consists of a J'S plate 36 and two guide rollers 37 rotatably attached to the support plate 36. The support plate 36 has mounting screws 38
It can be selectively attached to the housing 1 by means of the following.

Further, the rewinder unit 29 is removably attached to the housing l with a mounting screw 39, and the connector 40
A drive section (not shown) is provided therein, and a winding shaft 41 protruding laterally is formed.

Furthermore, the mount guide 30 is made of a plate material curved in a semi-circular arc shape, and a bent piece 4 is provided at one edge of the mount guide 30.
2 is bent, and an abutting portion 43 is bent at the other end. A cut piece 44 is disposed inwardly of the bent piece 42.
is bent, and the peeling plate 18 is held between the bent piece 44 and the bent piece 42, and the abutting portion 43
is detachably attached to the housing 1 by contacting the guide roller 26.

- 0- In the above configuration, in order to obtain a usage state in which the label 2 is printed and the backing paper 3 is wound up by the winding shaft 41 of the rewinder unit 29, it is necessary to install the label presence/absence detection means 2 in the housing 1.
7, the mount guide means 28, and the rewinder unit 29 are attached.

As a result, printing position control on label 2 is controlled by platen 1.
The bending of the mount 3 for peeling off the label 2 is performed by a tensile force based on the driving force from the rewinder unit 29. In this case, the force for bending the mount 2 may be quite weak, but
Even if the force from the rewinder unit 29 becomes large, the force is absorbed by the peeling plate 18, and the mount 3 and label 2 between the platen 11 and the thermal head 12 will not slip. Therefore, since the driving torque of the winding shaft 41 in the rewinder unit 29 is constant, a change in the winding diameter of the mount 3 with respect to the winding shaft 41 causes the mount 3 to
Even if the tensile force varies, the label peeling function will not be impaired, and the feeding speed of the label 2 during printing will not be varied and printing irregularities will not occur.

Next, when winding up the mount 3 together with the label 2 without peeling the label 2 from the mount 3, the mount guide 30, the mount guide means 28, and the rewinder unit 29 are attached to the housing 1. Thereby, the necessary information is printed on the label 2 by the printing mechanism 10, and the label 2 is wound up by the rewinder unit 29 without being peeled off from the mount 3.

In this way, on the production line at the factory, the standard machine 25 is manufactured, and four types of functional parts are separately manufactured: the label presence/absence detection means 27, the mount guide means 28, the rewinder unit 29, and the mount guide 3o. By manufacturing this, it is possible to provide various label printing machines that users need.

Effects of the Invention As described above, the present invention includes a label roll that is wound around a long mount to which a label is attached, a printing mechanism that prints on the label, a peeling plate that sharply bends the mount, and a peeling plate that sharply bends the mount. A standard machine having a built-in guide roller that determines the bending angle of the mount near the plate, a label presence/absence detecting means that is detachably attached to a label issuing port near the peeling plate, and a label presence/absence detection means that is attached to the peeling plate portion. a mount guide that is selectively attached to gently bend the mount; a mount guide that is selectively attached to the standard machine and defines a path for the mount together with the guide roller; a drive section; and a drive section driven by the drive section. Since the rewinder unit is equipped with a take-up shaft and a rewinder unit that can be detachably attached to the standard machine, the guide rollers provided in the standard machine are unnecessary when the mount is used with the paper flowing down. However, you can use the standard machine as is without attaching any additional parts to it, and when winding the backing paper, you can choose to use the backing paper guide depending on whether or not you want to peel off the label. By attaching a label presence/absence detection means, a mount guide means, and a rewinder unit, it is possible to add other functions to the standard machine, simplifying the production line at the factory and increasing the flexibility of the user's function selection. This has the effect of making it possible to improve the performance.
