Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a label sheet brake device that applies tension to a label sheet for printing in a label printer for a scale.

(Prior Art) As is well known, department stores and supermarkets are equipped with so-called cash registers and cashiers that calculate the prices of a wide variety of products being sold. In addition to calculating the unit price, weight, etc., a system is used in which a label is printed out and attached to the product or handed to the purchaser, which also serves as a record and issue of a receipt to the purchaser.

An example of a label printer for such a scale is
It is constructed as shown in FIGS. 7 to 12.
In other words, 1 is a scale connected to a weighing device (not shown) for weighing products, and is installed at the cash register of department stores and supermarkets, and is used to calculate data such as unit price, weight, total price, etc. for products to be sold. It has a mechanism to print out the data on a label. Operation section 4 on the front of this scale 1
The label roll 6 is configured such that the measurement data for the label is printed by operating a numeric keypad provided on the label printer 5, and the label roll 6, which is replaceably set on a mounting boss (not shown) of the label printer 5, is approximately parallel to the frame 19. It is set and prevented from coming off by a triangular mounting plate 20. The backing paper 7 of the label sheet 8 fed out from the label roll 6 is wound up by a winding device 9, and weighing data is printed by a printer 10 on labels (not shown) that are removably attached to the backing paper 7 at set intervals. It is configured to be sent out.

Further, between the label roll 6 and the printer 10, a brake device 11 is provided for applying tension to the label sheet 8 being fed to the printer 10.
It is fixed to a frame 19 via a bracket 12.

As shown in FIGS. 8 to 12, this brake device 11 is fixed in a position opposite to the label roll 6 side, that is, toward the lower left in the figure, and therefore The difference is that there is sufficient operation space between the frame 19 and the frame 19.

The guide 13 provided on the bracket 12 and allowing the mount 7 of the label sheet 8 to slide is L.
The label roll 6 of this guide 13 is formed into a mold.
On the opposite side, there is an auxiliary guide 14 with a U-shaped cross section.
A slit 21 is formed between the guide 13 and the auxiliary guide 14, which are integrally fixed and allow the label sheet 8 to pass relative thereto. A knob 18 for operating the brake shoe 16 is provided at a predetermined portion of the auxiliary guide 14 so as to be operable from a knob hole 22 . This knob hole 22 is bored in the auxiliary guide 14 to have a predetermined diameter size, and a long groove 23 is bored in communication with the knob hole 22 outwardly, that is, in a direction intersecting the label sheet 8.

The knob 18 is loosely inserted into the knob hole 22 so as to be movable back and forth, and a stem 17 having a stepped portion 24 that functions as a stopper extends backward through a small diameter neck portion, and the tip of the stem 17 is connected to the auxiliary guide 1.
Brake shoe 16 that can move back and forth in the longitudinal direction of 4
and are fixed together by welding.

A handle 25 is integrally formed and extended on the outer part of the brake shoe 16, and a hook 26 is formed at the tip of the handle 25 by bending it toward the label roll 6 side, so that it can be lightly hung with a fingertip. It is made possible.

Further, a plate 27 is loosely inserted into the stem 17 near the knob 18, and an elastic spring 1 is inserted between the plate 27 and the brake shoe 16.
5 is interposed to press the brake shoe 16 against the guide 13, and a label sheet 8 is interposed between the two to apply a predetermined friction to prevent overrun of the label sheet 8. A predetermined tension is applied between the printer 10 and the printer 10 to prevent this.

Therefore, the mount 7 of the label sheet 8 slides relative to the inner surface of the guide 13, and the label (not shown) attached to the label sheet 8 slides relative to the outer surface of the brake shoe 16.

Note that the knob 18 is screwed and fixed to the stem 17 to prevent it from coming off.

Then, the state shown in FIG. 10, that is, the knob 1
8 is in a position concentric with the knob hole 22 of the auxiliary guide 14, the knob 18 can be advanced to the loose insertion state, so the brake shoe 16 presses and clamps the label sheet 8 to the guide 13 by the elastic spring 15. Then, a predetermined tension is applied to the label sheet 8, and a brake operation is performed. On the other hand, as shown in FIG. 11, when the narrow diameter part of the stem 17 is in the narrow part of the long groove 23 of the auxiliary guide 14, the knob 18 is subjected to a stopper action, and the stem 1
7, the brake shoe 16 lifts up from the guide 13, and while maintaining that distance, the label sheet 8 is inserted through the slit 21, that is, the label roll 6
replacement, and brake device 11 and printer 10
It is possible to insert the label sheet 8 into the holder.

(Problems to be Solved by the Invention) However, in such a label sheet brake device, the brake can be released by operating the hook 26 of the brake shoe 16 with a fingertip.
Although it is designed to be extremely easy to operate, it is necessary to operate the brake manually, so it may be easy to forget to apply the brake. There was a problem in that the printing position on the label was shifted due to forgetting to apply the brake.

Therefore, an object of the present invention is to provide a label sheet brake device that can automatically apply the brake by closing the case door even if the user forgets to apply the brake.

(Means for solving the problem) In order to achieve the above-mentioned purpose, a guide is provided that provides a sliding surface for the label sheet, and a guide that provides elasticity for the label sheet that slides against the sliding surface during printer operation. It has a pressing position and a brake shoe that maintains a position away from the sliding surface when replacing the label sheet, and prevents overrun of the label sheet stretched from the roll to the take-up device via the printer. The label sheet brake device includes a handle connected to the brake shoe, an auxiliary guide that guides the brake shoe in a direction transverse to the running direction of the label sheet and in a direction toward and away from the label sheet, and a drawer of the handle provided on the auxiliary guide. an inclined surface that slopes away from the guide in the direction in which it is directed; a stem that is erected on the brake shoe and whose tip is inserted into a long groove provided in the direction of inclination of the inclined surface; A guide member movable on the stem, a spring provided compressed between the guide member and the brake shoe to press the brake shoe in the guide direction and press the guide member against the inclined surface, and a spring provided at the tip of the stem. A label sheet brake device characterized by comprising a knob.

(Function) In the brake device of the present invention, when the openable and closable case door is closed, the brake shoe is always deviated to the operating position, so that the printing position on the label sheet is not shifted.

(Example) Next, the first and second examples of the present invention are shown in Figs.
This will be explained with reference to FIG. In addition, since the basic structure of the brake device is the same as that shown in FIGS. 7 to 12 of the prior art, corresponding parts are given the same reference numerals and detailed explanation thereof will be omitted.

First, in the brake shoe 16 of the brake device of the embodiment described below, in its operating position, the handle 25 is housed inside the frame 19,
Another difference from the prior art is that in the non-operating position, the handle 25 has a length that projects outward from the closed position of the case door.

1 to 3, in the brake device, the brake shoe 16 is connected to the guide 13 via the elastic spring 15 in the operating position, similar to the conventional device.
In addition, the label sheet 8 is configured to be interposed between the brake shoe 16 and the guide 13 and run. Then, move the handle 25 in the direction of arrow A as shown in FIG.
When pulled in the opposite direction with a fingertip, the brake shoe 16 and the label sheet 8 are separated, and when pushed in the opposite direction with a fingertip, the brake shoe 16 is brought into pressure contact with the guide 13. On the other hand, the case door 30 is located on the side surface of the frame 19 and is configured to be openable and closable with a hinge 32.
The operator can open and close it as necessary, such as when replacing the label roll 6 (FIG. 3). When the case door 30 is closed from the open position shown by the two-dot chain line to the closed position shown by the solid line, the handle 25, which had been protruding as shown by the two-dot chain line, is moved from the non-operating position as the hook 26 is pressed. The label sheet 8 is brought into an operating position in which a predetermined tension is applied. In this way, even if you forget to apply the brake by pressing the handle 25 with your fingertip, you can apply the brake by closing the case door 30.

Next, referring to FIGS. 4 to 6, the second part of the present invention will be described.
An example will be explained. In this embodiment, the auxiliary guide 14 is formed with an inclined surface 14a having a portion close to the guide 13 and a portion separated from the guide 13. This inclined surface 14a has long grooves 33 having the same width and extending in a direction perpendicular to the running direction of the label sheet 8.
The stem 17 of the brake shoe 16 is held in place by a knob 34 provided on the stem 17 disposed in the long groove 33 and a guide member 35 pressed against the inner surface of the auxiliary guide 14 by a spring 15. Since the brake shoe 16 is guided along the long groove 33, the brake shoe 16 is slidably disposed within the auxiliary guide 14 between a close portion on the left side of the figure, that is, an operating position, and a distant portion, that is, a non-operating position. ing. The brake device of the second embodiment configured in this way has a brake shoe 16 similar to the first embodiment.
The handle 25 can be pressed by closing the case door 30 to bring the brake shoe 16 into the operating position as shown in FIG.

(Effects of the invention) As described above, in this invention, the brake shoe is configured to be activated by the case door, so even if you forget to apply the brake, the brake can be applied automatically by closing the case door, and the brake shoe can be applied automatically by closing the case door. There are no printing errors caused by forgetting to apply the brake, and a safe and reliable brake device can be obtained. Furthermore, as before,
When removing a used label sheet from the weighing machine, there is no need to pull up the knob and then pull out the handle. Simply pull out the handle to release the brake shoe from pressing against the guide.
It has superior operability compared to conventional ones.
