Description

[Detailed Description of the Invention] This invention relates to a label printer that prints the weight, price, etc. on a label after measuring the weight.

First, the conventional structure of this type of device is shown in FIGS. 1 and 2.

1 is a main body, and the inside of this main body 1 is partitioned by a side frame 2 into an electronic weighing chamber 3 and a label printer chamber 4.

A display section 5 and an operation section 6 are provided on the outer surface of one electronic weighing chamber 3, and a saucer 7 is provided on the upper surface, and the load applied to the saucer 7 is converted into an electrical signal (not shown) inside. Known electronic scale components are housed therein, such as a conversion section for calculating the price and a calculation section for calculating the price based on the unit price and weight set by the operation section.

The label printer chamber 4 houses various label printer mechanism parts held by the side frame 2.

That is, as shown in FIG. 2 (side view), a supply roller 10 and a take-up roller 11 are provided which wind and hold both ends of a long mount 9 on which a plurality of labels 8 are pasted at equal pitches. In the path of the mount 9, there are a mount presser 12, a label detector 13, a printer section 14, a product name mark 15, and a label peeling section 1.
6, a feed roller 17, and a push roller 18 are provided.

The take-up roller 11 and the feed roller 17
is connected to the motor 21 by a bell} 19.20.

Further, a label issuing port 22 is formed on the front surface of the label printer chamber 4.

Therefore, when the weight is measured, the weight, price, etc. will be displayed on the display section 5.
The value is also output to the printer section 14 as an electrical signal.

As a result, the printer section 14 operates to print the price and weight on the label 8, and also stamp the product name using the product name stamp 15.

Next, the motor 21 rotates at a certain angle and the take-up roller 11 takes up the mount 9, but the label 8 is peeled off by the peeling section 16 and issued from the label issuing port 22.

The actions so far have been performed by known means, but
When replacing the mount 9, etc., a shaped door (not shown) on the side of the label printer chamber 4 is opened.

At this time, since there are many label printer mechanism parts 10 to 21 in the label printer chamber 4 and the path of the mount 9 is curved, replacing the mount 9 is extremely troublesome, and it is easy to insert the mount 9 into the wrong position. be.

Furthermore, the presence of the motor 21 has the disadvantage that the label printer chamber 4 becomes larger.

This invention focuses on creating a label printer that can eliminate the above-mentioned drawbacks.

This invention has an electronic weighing chamber and a label printer chamber separated by a side frame inside the main body case, and the label printer mechanism parts held by the side frame are housed in this label printer chamber. Among the label printer mechanism parts, a motor that drives a take-up roller for winding a mount is housed in the electronic weighing chamber together with an electronic weighing structure or parts, and three legs, each of which is positioned at a corner of a triangle and supports the main body case, are housed in the electronic weighing chamber. Two of them are fixedly installed at the bottom of the electronic weighing chamber, and one is fixedly installed at the bottom of the label printer chamber.

Therefore, since there is no motor in the label printer room, the label printer room can be made smaller, and there is more space around the mount, so the mount can be replaced extremely easily. The legs that support the main body case are two fixed to the bottom of the electronic scale chamber that houses the heavy motor, and one leg is fixed to the bottom of the label printer chamber, so that the weight distribution is good and the main case can be stably supported. It was something like that.

An embodiment of this invention will be explained based on FIGS. 3 to 6.

Components that are the same as those described in FIGS. 1 and 2 are designated by the same reference numerals, and explanations thereof will be omitted.

23 is a main body case, and inside this main body case 23 is a bottom plate 2.
An L-shaped side frame 26 consisting of a vertical plate 25 and a vertical plate 25 is fixedly provided.

This main body case 23 is partitioned into an electronic weighing chamber 3 and a label printer chamber 4 by the vertical plate 25.

Legs 27 are fixed to the outer front and rear portions of the bottom plate 24, and arms 27 are also fixed to the lower surface of a support portion 28 extending outward from the lower center of the vertical plate 25.

That is, two legs 27 are fixed to the bottom of the electronic weighing chamber 3, and one leg 27 is fixed to the bottom of the label printer chamber 4, and each of these legs 27 is positioned at a corner of an isosceles triangle. ing.

The take-up roller 11 is located immediately after the peeling section 16, and is directly connected to the motor 21 housed in the electronic weighing chamber 3 while being held by the vertical plate 25 of the side frame 26.

There are doors 29 on both sides of the main body case 23. 30
A panel is removably attached to indicate the function.

Note that the bottom of the electronic weighing chamber 3 is connected to the bottom plate 2 of the side frame 26.
4, but the bottom plate 31 of the label printer chamber 4 is provided on the main body case 23 side.

The bottom plate 31 has an opening facing the support portion 28.

In such a structure, the function of measuring the weight and issuing the label 8 is as described above, but since the motor 21 is housed using the space of the electronic weighing chamber 3, the label printer chamber 4 is made smaller. I can do that.

Further, there is more space around the mount 9.

In particular, by locating the take-up roller 11 immediately after the peeling section 16, the space around the mount 9 becomes even more spacious and the path becomes extremely neat.

This makes it extremely easy to replace the mount 9 by opening the door 30.

Furthermore, since the motor 21 and the take-up roller 11 are directly connected, it is possible to eliminate the need for extra power transmission parts.

Then, an electronic weighing chamber 3 that accommodates the heavy motor 21 is provided.
By fixing two legs 27 to the bottom of the other label printer chamber 4 and fixing one leg 27 to the bottom of the other label printer chamber 4, the main body case 1 can be stably supported with good weight distribution.

As mentioned above, this idea houses the motor that drives the take-up roller in the electronic weighing chamber, making it possible to downsize the label printer room and provide more space around the mount, which allows for frequent operations. In addition, by supporting the main body case with three legs placed at the corners of a triangle, the vibrations are well-balanced regardless of the flatness of the floor surface. The main body case can be supported without moving, and even when a heavy motor is installed in the electronic weighing chamber, two of the three legs are fixed to the bottom of the electronic weighing chamber, which improves weight distribution. This has the effect of making it possible to improve the balance even further.
