Description

[Detailed description of the invention] <Industrial application field> The disclosed technology is a technology for the structure of a holder attached to the spindle of a sheet roll in which a tape-like sheet from a label roll or the like is wrapped around a core tube to be attached to distributed products. Belongs to a field.

<Summary of the gist> Therefore, this invention unwinds a sheet roll, such as a label roll, in which labels, etc. are continuously pasted on a tape-like backing paper at equal intervals and wound around a cylindrical core tube. Alternatively, when the sheet roll is attached to a cantilever-type support shaft provided on the frame of the rewinding device, a ring-shaped groove for locking formed at the end of the support shaft has a function of preventing the sheet roll from falling off. This invention relates to the structure of a plate-shaped sheet roll guard to be hung, and in particular, the sheet roll guard is made of a rectangular plate, and a circular hole is provided at a predetermined position through which a support shaft is inserted, and one side of the sheet roll guard, or is provided with a slit notch on both sides, and the slit notch is adapted to be freely latched into a ring-shaped groove for latching that is smaller in size than the outer diameter of the spindle at the end of the spindle. This invention relates to a sheet roll guard structure in which the length from the center to the end of the sheet roll guard is longer than the vertical distance between the support shaft and the bottom inner surface of the device frame.

<Prior Art> As is well known, products sold in distribution departments, such as supermarkets, are often priced by pasting labels that display unit price, weight, total price, etc.; however, such labels are supplied using tape. In most cases, this is done by unwinding a sheet from a sheet roll wrapped around a core cylinder made of cardboard, etc., and is used when pricing products with different weights for each item, and the price of each item is fixed. When attaching a large amount of adhesives to fixed price products in advance in the back yard, or when issuing receipts at a register, etc.
The same applies to the case of supplying receipt paper, and accordingly, sheet rolls of the maximum size permitted by the sheet roll storage capacity of registers, receipt issuing machines, label printers, etc. are used.

In this case, for example, a label printer type printer is briefly explained in FIG. 1. A label roll 1 of a predetermined length is a sheet of mount paper with a large number of labels pasted adjacent to each other in advance on a core tube 2 made of paper or the like. The sheet 4 is wound up and loosely supported on a support shaft 3 of the device, and the sheet 4 is guided by a guide 5, fed out via a drive roller 6, and printed with predetermined information such as price and weight on a label by a printing machine 7. It is designed to be printed.

At this time, in order to speed up the loading and unloading of the label roll 1 on and off the support shaft 3 and improve serviceability, the support shaft 3 is provided in a cantilever type on the device frame 8 as shown in FIG. Depending on the design, a flange 9 is provided on one side so that the label roll 1 can be loaded and unloaded from the other side.

Depending on the tension relative to the sheet 4, the support shaft 3 may be of a fixed type or rotatable type, but in either case, the label roll 1 is rotatable after being set. Therefore, it goes without saying that the label roll 1 may fall off from the spindle 3 during operation.
In order to prevent lateral movement in the axial direction, a sheet roll guard as a stopper is provided at the end of the support shaft 3.

For example, as shown in FIGS. 2 and 3, a knob bolt 10 is screwed onto the end of the support shaft 3, and the center hole 12 of the plate-shaped sheet roll guard 11 is inserted from the head of the knob bolt 10 in the direction A in the figure. The thin slit 13 is engaged with the screw shank of the knob bolt 10, and the knob bolt 10 is fastened to attach the sheet roll guard 1 to the support shaft 3.
1 was fixed and used.

<Problem to be solved by the invention> However, the seat roll guard 11 of the stopper of this type is rotated by the knob bolt 1 as the roll 1 rotates.
There is a risk that the sheet roll guard 11 will fall off together with the knob bolt 10 by rotating the sheet roll guard 11 along with the knob bolt 10, or the sheet roll guard 11 will be displaced in its longitudinal direction and the center hole 12 will move, causing the knob bolt 10 to become loose. There was a drawback that it could come off the head.

In addition, the knob bolt 10 has the drawback that it is difficult to maintain and manage the knob bolt 10 as a component, and it is difficult to work with it, including machining female threads, and it also has the disadvantage of high cost.

<Purpose of the invention> The purpose of this invention is to solve the problems of the sheet roll guard based on the above-mentioned conventional technology as a technical problem, and to make it easy to set and secure regardless of the type of rotation and stop of the spindle. During operation, the sheet roll can be used for axial restraint, and in addition,
It is an object of the present invention to provide an excellent sheet roll guard structure that facilitates the loading and unloading work of sheet rolls and is beneficial to the field of printing technology application in the distribution industry.

<Means/effects for solving the problems> In order to solve the above-mentioned problems, the structure of this invention, which is based on the scope of the above-mentioned utility model registration claims, is to solve the above-mentioned problems. The sheet roll is set by inserting the core cylinder from the outside of the sheet roll onto a support shaft provided in a cantilever type on the frame of the device, and the circular hole of the plate-shaped sheet roll guard is exposed to the outer shaft end of the support shaft. The sheet roll guard is pushed into the sheet roll, and one of a pair of slit notches integrally formed adjacent to the circular hole of the sheet roll guard is engaged with a small-diameter ring-shaped groove for locking formed on the support shaft to prevent it from coming off. It is automatically latched, and the lower end of the sheet roll guard is brought into contact with the bottom inner surface of the equipment frame, and the length from the center of the sheet roll guard to the end is longer than the vertical distance between the support shaft and the bottom inner surface of the equipment frame. By forming the sheet roll guard in a tilted position with respect to the frame, the sheet roll guard is actively kept in a non-rotating state, thereby preventing the rotating sheet roll from falling off the support shaft via the stationary sheet roll guard. A technical measure has been taken to ensure that the sheet is fed out smoothly without any problems.

<Embodiment - Configuration> Next, an embodiment of this invention will be described based on the drawings from FIG. 4 onwards. Note that the same parts as those in the conventional embodiment shown in FIGS. 1 to 3 will be described using the same reference numerals.

In the embodiment shown in FIGS. 4 to 6, reference numeral 1 denotes a label roll, which is attached to a label printer 14 such as a supermarket, as in the conventional embodiment described above, and is attached to a frame 8' of the label printer 14. A tape-like sheet 4 is continuously wound in advance around a cylindrical paper core tube 2 in order to be set on a support shaft 3' which is horizontally installed in a cantilever manner and protrudes from a set part of the sheet, and is made into a unit. ing.

A presser flange is fixed to the frame 8' side of the support shaft 3', and a presser flange is fixed to the end of the support shaft 3' on the other side, as shown in FIG. Three ring-shaped grooves for locking at the width position 15,1
5 and 15 are formed with a set small diameter size.

And 11' is the setting width which forms the gist of this invention.
It is a plate-shaped sheet roll guard made of metal with a suitable length and thickness, and both ends thereof are formed into rounded parts 16, 16, and a circular hole 17 in the center into which a support shaft 3' can be inserted relatively freely. is bored, and on both sides of the circular hole 17 in the longitudinal direction are ring-shaped grooves 15, 15 whose width is the support shaft 3'.
Slit notch 1 of the same size as the maximum diameter of...
8 and 18 are bored as one pair.

Therefore, from the outer end of each slit notch 18, the rounded portions 16, 16 of the sheet roll guard 11'
Although the lengths to both ends are different, they are plane or line symmetrical with respect to the center of the circular hole 17.

As shown in FIG. 6, the length from the center to the end of the sheet roll guard 11' is longer than the vertical distance between the support shaft 3' and the internal bottom surface of the device frame 8'. In addition, the sheet roll guard 11' is obliquely provided between the rounded portion 16 at the outer end of the sheet roll guard 11' and the inner bottom surface of the device frame 8' to prevent rotation.

Note that a guide 5 is provided on the upper part of the support shaft 3' of the label printer 14, as in the conventional embodiment, and a drive roll 6 is provided at the front of the guide 5, facing the printing machine 7.

<Embodiment - Effect> In the above-described configuration, the label roll 1, which has been previously wound around the core tube 2, is set on the support shaft 3' with the guard removed as shown in FIG.
With the sheet roll guard 11' in a nearly horizontal state, a circular hole 17 is formed in the center of the guard 11', and a slit notch 18 is inserted into the ring-shaped groove 15 closest to the outer surface of the label roll 1. When they are slid into engagement and released, the far end falls due to its own eccentric weight, and as shown in FIG. Since the length from the center of the sheet roll guard 11' to the inner bottom surface 8' of the apparatus frame is longer than the vertical distance from the support shaft 3' to the apparatus frame, the apparatus does not rotate while maintaining an inclined posture.

Then, the leading edge of the sheet 4 is passed through the guide 5, the printing machine 7, and the drive roll 6 in a predetermined manner to complete the setting, and the label printer 14 is put into operation.

Therefore, when the label printer 14 is operated, the drive roller 6 rotates in a predetermined manner, prints predetermined items on the label of the sheet 4, feeds out the sheet 4 at set intermittent timing, and rotates the label roll 1 in the direction of the arrow.

During this time, the outer surface of the label roll 1 comes into sliding contact with the sheet roll guard 11', but as shown in FIG. Because it makes point contact and is tilted at a predetermined angle, it does not rotate and remains stationary.

Therefore, the sheet roll guard 11' does not rotate, and its slit notch 18 is engaged with the ring-shaped groove 15 of the support shaft 3' and will not come off. As long as this is the case, the label roll 1 will not come off the label printer 14.

When the core tube 2 is removed after all the sheets 4 are unrolled, the sheet roll guard 11' is simply removed.
It is only necessary to move the support shaft 3' in its longitudinal direction, bring the support shaft 3' and the circular hole 17 into a concentric position, and then remove the support shaft 3'.

In addition, in the embodiment shown in FIG. 7, a weight 1 such as a piece of iron is attached to one end of the sheet roll guard 11'' in contrast to the above-mentioned embodiment.
9 is attached integrally with an adhesive or the like, and the appearance of a natural inclined state can be actively achieved.

It goes without saying that the embodiments of this invention are not limited to the above-mentioned embodiments. For example, it is possible to use a roll guard with different lengths at both ends from the circular hole, or to increase the area of one end to reduce the weight. Various aspects can be adopted, such as increasing the size or making the slit notch shape bent, and the support shaft is not limited to a fixed type, but can also be applied to a rotating type.
The sheet roll can be one with pre-printed paper, one with blank paper, or one with a release liner. <Effects of the invention> As described above, according to this invention, the receipt issuing machine of the label printer that is indispensably used in the distribution sector can be applied. The sheet roll guard used as a sheet roll holder, such as the Not only is the excellent effect that it can be done at low cost, but also the excellent effect that it can be attached and detached with one touch, and that setting and resetting of devices such as label printers can be done reliably and quickly.

Moreover, once installed, it will not come off without permission, so it is highly reliable and has good serviceability.

Therefore, by providing slit notches on both longitudinal sides of the circular hole drilled in a predetermined part of the plate-shaped sheet roll guard into which the support shaft is inserted, the support shaft is inserted into a ring-shaped groove at the end of the support shaft. Cover the circular hole with the shaft, loosely insert the sheet roll guard, and then
The roll guard can be set with one touch by simply engaging the slit notch with the ring-shaped groove.
The effect is that the operation work is easy to perform.

Further, after setting, one of the slit notches engages with the support shaft, so that the center of gravity of the sheet roll guard is offset and the sheet roll guard does not rotate along with the roll due to its own weight.

Moreover, since the length from the center to the end of the sheet roll guard is longer than the vertical distance between the support shaft and the bottom inner surface of the equipment frame, the sheet roll guard always maintains a stationary tilted position even during operation. However, since it does not rotate, it is possible to prevent not only the sheet roll guard from falling off, but also the sheet roll from falling off.

Therefore, it is flexible enough to be applied whether the support shaft is a fixed type or a rotary type.
