Description

[Detailed explanation of the idea] The present invention relates to a label printing device.

An example of a conventionally known label printing device will be explained based on FIG. 1. Reference numeral 1 denotes a peeling plate for printing, and a peeling mount with a label 2 is sent out horizontally from inside the printer (not shown). 3 is pulled downward at the edge of the peeling plate 1, and the label 2 is peeled off from the mount 3.

Reference numeral 4 denotes a fixing plate disposed above the peeling plate 1, 5 a support rod passing through approximately the center of the fixation plate 4, 6 a bar with a magnet 7 fixed to the lower end of the support rod 5, and 8 The deck is attracted to the magnet 7, 9 is a spring that urges the support rod 5 upward, 10 is a solenoid, 11 is rotatably supported at the center by a fixed shaft 12, and a notch 13 at one end is connected to the an interlocking rod that engages with the pin 14 of the support rod 5 and whose elongated hole 15 at the other end engages with the pin 16 of the plunger 10a of the solenoid 10;
17 is a guide rod of the bar 6.

In such a configuration, from the state shown by the solid line, the solenoid 1
0 is activated to move the plunger 10a upward, the deck 8 is pressed against the label 2 on the peeling plate 1 via the interlocking rod 11, the support rod 5, and the bar 6, as shown by the imaginary line, and printing is performed. However, the structure is relatively complicated, and there are a solenoid 10, a spring 9, a support rod 5, etc. above the peeling plate 1, and the overall size of the device increases accordingly.

Therefore, the present invention provides a label printing device that solves these problems.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

20 is a printer, 21 is a printer drum, 22 is a peeling plate that extends horizontally from the printer 20 and also serves as a marking stand.
Reference numeral 23 is a pull-type lever, and the main body 23a is fixed to the lower surface of the peeling plate 22 with a nut 24, and the plunger 23b extends upward through the peeling plate 22.

A bar 25 is fixed to the upper end of the plunger 23b with a screw 26, and extends horizontally along the longitudinal direction of the peeling plate 22.

A spring 27 is fitted onto the plunger 23b and urges the bar 25 upward.

31 is a screw 32 fixed to the lower surface of one end of the bar 25, and a round bar 34a extending downward through a hole 33 formed in the peeling plate 22 is a stopper nut screwed into the upper threaded portion of the round bar 31. , 34b is a lock nut, and 35 is a rubber plate fixed to the lower surface of the stopper nut 34a.By turning the nut 34a, the gap α between the rubber plate 36 and the peeling plate 22 is adjusted. , the amount of pressing of the printing plate 29 against the label 2 can be adjusted.

36 is a bolt that is screwed into a screw hole at the lower end of the round bar 31 via a flat washer 40; 37 is a weight that loosely fits into the round bar 31 and also serves as a stopper placed on the washer 40; Plunger 2 via round rod 31 and bar 25
3b is prevented from being removed from the main body 23a by the spring 27.

28 is a round bar 3 with the plunger 23b of the bar 25 in between.
A magnet 29 is fitted into a U-shaped portion 25a formed at a proper position on the opposite side from 1, and a printing plate 29 is attracted to the magnet 28.

The rear side wall 30 of the U-shaped portion 25a extends downward longer than the front side, and is used for positioning the printing plate 29.

Further, the printing plate 29,
The structure is such that the magnet 28, etc., the round bar 31, the stopper nut 34a10, the nut 34b1, the weight 37, etc. are almost balanced.

In the above configuration, when the solenoid 23 is actuated and the plunger 23b is pulled downward against the spring 27 from the state shown by the solid line in FIG. 2, and predetermined characters, symbols, etc. are printed on the label 2.

In this case, the load applied to the plunger 23b is approximately equal on the left and right sides, and the round bar 31 is attached to the hole 3 of the peeling plate 22.
Since the plunger 23b penetrates through and acts as a guide rod, the plunger 23b can move up and down smoothly.

In the above embodiment, the peeling plate 22 was used as a stamp stand, but a stamp stand may be provided separately from the peeling plate 22, and the printing plate 29 may be pressed against the label 2 on the stamp stand.

Further, if the weight of the round bar 31 is increased, the weight 37 can be omitted.

In this case, the washer 40 instead of the weight 37 prevents the plunger 23b from being removed.

As described above, the label printing device of the present invention includes a solenoid whose main body is disposed below the marking stand and whose plunger extends upwardly through the marking stand, and a bar whose intermediate portion is fixed to the plunger. A round bar is provided that extends downward from one end of the bar through the hole in the marking stand, and stoppers are respectively provided at the upper and lower parts of the round bar at a predetermined distance from the marking stand, and the plunger of the bar is inserted between the ends of the bar. The printing plate is removably attached to a suitable position on the opposite side of the round bar, and the stopper at the upper part is formed with a male threaded part on the outer periphery of the round bar, and a stopper nut is screwed into this male threaded part, The stopper nut is configured so that it comes into contact with the top surface of the marking stand as the plunger descends, and the loads on both sides of the bar are balanced with the axis of the plunger as a boundary, so the following effects can be obtained. .

1 The main body of the solenoid is not located above the marking stand,
Since it can be placed below the marking stand, which is usually left as a waste of space, the entire carriage can be made smaller than the conventional example mentioned at the beginning.

2. For the stopper at the upper part, a male thread is formed on the outer periphery of the round bar, and a stopper nut is screwed into this male thread,
Since the stopper nut is configured to come into contact with the upper surface of the printing plate as the plunger descends, the lowering position of the printing plate can be adjusted with a simple structure.

3 Since the structure is such that the loads on both sides of the bar are balanced with the axis of the plunger as a boundary,
The bar can be expected to move more smoothly than a bar in which the opposite side of the bar from where the printing plate is attached is biased upward by a spring.

This is because in this invention, the load on both sides of the bar is the same and the loads are balanced, so when the plunger is driven, the inertial force on both sides of the bar is the same, and the bar is This is because no twisting occurs at the joint with the plunger shaft, and dynamic balance can be obtained.

On the other hand, with the conventional bar in which one side of the bar is biased by a spring, even if static balance is satisfied, when the plunger is driven, inertia force acts only on the printing plate side, so the joint part If the bar becomes distorted, smooth movement of the bar cannot be expected.

4. A round bar installed on the opposite side of the bar from the side where the printing plate is attached so that the load is balanced is not only a balance weight, but also acts as a means of adjusting the vertical movement position of the bar, and requires only a small number of parts. A sufficient effect can be obtained with the number of points.
