Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a label strip in which a plurality of labels are successively temporarily attached to a band-shaped mount, and the mount of the label band is turned around in a label peeling section, thereby peeling the label from the mount. The present invention relates to a peeling device, and particularly to a device configured to more reliably peel a label.

Label peeling devices of this type are widely employed in label printing and applicator machines, metering printers, or other label printing machines. however,
In order to manufacture the entire label strip at a low cost, labels and mounts made of inexpensive, coarse-grained paper are used, or a release agent is applied to the label temporary side of the mount to make it easier to peel off the label from the mount. Attempts have been made to apply the mold agent thinly and roughly. For this reason, the label itself has little rigidity, and since the backing paper is coarse, the release agent soaks into the backing paper and becomes thinner, and the applied release agent becomes uneven. Therefore, even if the mount is turned at the label peeling section, the label often cannot be completely peeled off from the mount. If the label is not peeled off from the mount in this way, not only will the label not be issued, but the label will stick to the mount transport path, making the machine inoperable or causing a malfunction.

The present invention has been made in view of the above points, and even if the label band is manufactured at low cost and has uneven adhesive strength between the backing paper and the label, it is possible to reliably separate the label from the backing paper. An object of the present invention is to provide a label peeling device that can peel labels.
In order to achieve this purpose, in the present invention, the mount of the peeling part and the label are located close to the position where they are separated,
In addition, a rotating body that can freely rotate by contacting with the label is disposed in the direction in which the label travels, and labels that cannot be peeled off simply by turning the backing paper also come into contact with this rotating body and advance while rotating the rotating body. The structure is such that it can be reliably peeled off without resistance.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

The label strip 1 wound and held by the supply section 22 is supplied to a label peeling device 23 according to the present invention.
This label peeling device 23 includes a transfer section 24 that appropriately transfers the label strip 1, and a transfer section 24 that appropriately transfers the label strip 1, and a label peeling device 24 that converts only the mount 2 of the label strip 1 near the front lower end of the main body 11 so that the label 3 is separated from the mount 2 by the rigidity of the label 3 itself. A peeling section 30 that peels off the
The rotating body 33, which is the gist of the present invention, is provided close to the position where the mount 2 and the label 3 are separated.

The transfer section 24 includes both side plates 11a of the main body 11,
It has a transfer drum 26 rotatably supported by a shaft 25 installed between 11b and a hook 27. On the outer peripheral surface of the transfer drum 26, transfer pins 26a that engage with the holes 6 of the label band 1 are provided at regular intervals, and on one side, engaging pins 26b that engage with the hooks 27 are provided as transfer pins. The same number as 26a are provided. The hook 27 is pivotally connected at one end to the operating lever 15 by a pivot pin 28.
When the other end engages with the engagement pin 26b, the transfer drum 26 is appropriately rotated as the operating lever 15 reciprocates, and the label strip 1 is transferred. A spring 29 biases the hook 27 toward the engagement pin 26b.

have. This bottom cover 35 is attached to both side plates 11a and 11b of the main body 11 by a pivot 34 so as to be openable and closable.

The peeling portion 30 includes both side plates 11a of the main body 11,
Upper regulating members 3 integrally formed on each of the upper regulating members 11b
1, and a lower regulating member 32 that is integrally provided to the connecting portion 35c of the bottom cover 35. The upper regulating member 31 and the lower regulating member 32 are arranged with a slight interval between them.
By turning only the mount 2 of the label band 1 between labels 1 and 32, each label 3 is peeled off from the mount 2 by its own rigidity.

A pin 36 is fixedly installed between both side edges 35a and 35b of the bottom cover 35 so as to be located near the peeling part 30. The rotating body 33 made of a helically formed member is wound around this pin 36 . Rotating body 33 made of a spiral member
is close to the position where the mount 2 and the label 3 are separated, and is rotatable relative to the pin 36 in the traveling direction of the label 3. As shown in an enlarged view in FIG. 4, the outer circumferential surface of the rotating body 33 is located slightly below the plane that includes the traveling direction of the label 3 that is normally peeled off, that is, the label 3 is peeled off normally. This is provided at a position slightly lower than the peeling part 30 (FIG. 2) so that the adhesive 5 of the label 3 can be seen. It is more preferable that silicone resin or the like is applied to the rotating body 33 configured in this way to prevent the label 3 from sticking.

In FIG. 2, 37 and 38 are label strip 1
This is a guide member for engaging the entire hole 6 and the hole 6 of only the mount 2 with the transfer pin 26a of the transfer drum 26, respectively, and 39 is a platen that receives the printing pressure of the printer 16. Reference numeral 40 denotes a roller for attaching the label 3 delivered from the label delivery window 35d formed in the bottom cover 35 to an article, etc., and is rotatably supported by the pivot shaft 34.

Next, the operation of the above embodiment will be explained.

First, the insertion of the label strip 1 is performed by opening the bottom cover 35 and separating the lower regulating member 32, the rotating body 33, and the guide member 38 from the passage of the label strip 1 and the mount 2, and also interlocking with the opening of the bottom cover 35. The guide member 37 may be separated from the path of the label band 1 or individually to facilitate the above-mentioned insertion. When the hand lever 13 is grasped after the guide member 37 and the lower lid 35 are closed, the hand lever 13 and the operating lever 15 rotate counterclockwise (FIG. 2) against the biasing force of the return spring 21. do. Actuation lever 1
5, the printing device 16 descends, and the selected type 17a of each type wheel 17 is printed by the ink roller 1.
After the ink is applied at step 8, the label 3 on the platen 38 is printed.

When the hand lever 13 is released, the return spring 2
1 by hand lever 13 and actuating lever 1
5 rotates clockwise in FIG. 2 and returns to its original position, and the printing device 16 rises. In conjunction with this operation, the transfer drum 26 of the transfer unit 24 rotates counterclockwise, so that the transfer drum 26 transfers the label strip 1 at its upper portion and the turned mount 2 at its lower portion.

As described above, only the mount 2 of the label strip 1 transferred by the transfer section 24 is turned around at the peeling section 30. As a result, the printed label 3 is peeled off from the mount 2 due to its own rigidity, and is temporarily held by the rotating body 33 until it is pasted onto an article or the like by the pasting roller 40.

However, not all the labels 3 are necessarily peeled off from the mount 2 by turning the mount 2 in the peeling section 30 . That is, label 3
Some materials have weak rigidity, and depending on the quality and application state of the release agent 4 and adhesive 5 applied to the mount 2 and label 3, respectively, the label 3 may be required for the mount 2. There are some that are even more tentative than that. Label 3 of label band 1 under these conditions
is not completely peeled off from the mount 2 and often turns around together with the mount 2.

However, in this embodiment, the rotating body 33 is provided close to the position where the mount 2 and the label 3 are separated, and located slightly below the plane that includes the traveling direction of the label 3 that is normally peeled off. It is being Therefore, the label 3, which is not completely peeled off from the backing paper 2 and is turning along with the backing paper 2, also comes into contact with the rotating body 33 near its tip as shown in FIG. 4, and moves while rotating the rotating body 33. This will ensure that it is removed. During this peeling, the label 3 advances while in contact with the rotary body 33, and the rotary body 33 rotates in the direction of travel as the label 3 advances. Therefore, the contact resistance of the label 3 with the rotating body 33 is extremely small, and the label 3 can be peeled off more smoothly.

In addition, in the said Example, the peeling part 30 which turns the mount 2 and peels off the label 3 is comprised from the upper regulation member 31 and the lower regulation member 32, as an example. However, it is also possible, for example, to use the tip of the platen 39 as the peeling section 30 and to turn the mount 2 by wrapping it around the tip of the platen 39. In this case, the transport drum 26 can transport the label strip 1 and peel off the labels 3 simply by pulling the turned mount 2.

Further, the rotating body 33 is attached to a bottom cover 35, and when the label strip 1 is inserted, the bottom cover 35 is opened and the rotating body 33 is attached to the bottom cover 35.
A configuration is illustrated in which the above-mentioned insertion is facilitated by separating the label band 1 from the path of the label band 1. However, if the structure is such that the front or side surfaces of the main body 11 are opened and closed when the label strip 1 is inserted, the rotating body 33 can be attached to those opening/closing parts, or the insertion of the label strip 1 can be easily made by other means. This allows the rotating body 33 to be fixed to a portion of the main body 11 that does not open or close.

Further, in the above embodiment, the rotating body 33 is constructed of a spiral member rotatably wound around the pin 36, but the rotating body 33 may be constructed as shown in FIGS. 5 to 8, respectively. You can also. That is, the example of the rotating body 41 shown in FIG. 5 consists of a required number of rollers rotatably supported by pins 42 fixedly installed on both side edges 35a and 35b of the bottom cover 35. These rollers have sharp outer peripheries to reduce the contact area with the label 3. In addition, the rotating body 4 shown in FIG.
Example No. 3 consists of a roller integrally formed with a shaft 44 rotatably supported by both side edges 35a, 35b of the bottom cover 35. The rotary body 45 shown in FIG. 7 is composed of a roller integrally formed with a rotatable shaft 46 similarly to the example shown in FIG. A protrusion 4 consisting of a plurality of annular shapes
5a is formed. Rotating body 47 shown in FIG.
Similarly, it consists of a roller formed integrally with a rotatable shaft 48, and has a large number of protrusions 47a formed on its outer peripheral surface for the same purpose as the example shown in FIG.

Next, a second embodiment of the present invention will be described with reference to FIGS. 9 to 11. This embodiment shows an example in which a label peeling device according to the present invention is applied to a printer such as a weighing printer.

In FIG. 9, reference number 51 is a supply section attached to the main body 50 of the printer, and this supply section 5
1 winds and holds a label band 1 as shown in FIG. The label strip 1 supplied from the supply section 51 is guided by a guide roller 52 and then passes through a transmission type photoelectric detector S, a printing section 53, and a stamp section 54.

The photoelectric detector S detects the label strip 1 for transport control.
The sensor is arranged so as to detect the hole 6 and output a signal. The printing section 53 facing the platen 55 is
For example, it has a print head 56 of a thermal printing type, and is configured to print print data from a measuring device, a keyboard, etc. (not shown) on the label 3. Further, the stamp unit 54 facing the printing stand 57 prints fixed data on the label 3 using a stamp 59 driven by the solenoid M.

The label strip 1 that has passed through the stamp section 54 reaches a label peeling device 60 that includes a peeling section 61, a transfer section 62, and a rotating body 63, which is the gist of the present invention.

The peeling section 61 is configured to utilize the edge of the tip of the stamp stand 57, and the label 3 is peeled off from the mount 2 by turning only the mount 2 of the label band 1 at the peeling section 61.

The transfer unit 62 includes a drive roller 64 and a driven roller 65 that grip and pull the turned mount 2, and a pulse motor PM that rotationally drives the drive roller 64. The transport section 62 is driven and controlled by a transport signal generated based on a print completion signal, an output signal from the photoelectric detector S, etc., and transports the entire label strip 1 by pulling the mount 2. 66
is a winding unit that winds up the transported mount 2 as appropriate.

As shown in FIGS. 10 and 11, the rotating body 63 is composed of a spiral member wound around a U-shaped pin 67, and has a structure capable of rotating in the direction in which the label 3 is transported. The pin 67 is implanted at the upper end of a rotating plate 69 that is pivotally connected to the main body 50 by a pivot 68 . The rotating plate 69 has a spring hook member 70 located in a notch 69a formed at the lower center.
is fixed, and a spring 71 is stretched between this spring hanging member 70 and a spring hanging member 72 of the main body 50. Therefore, the rotating plate 69
It can swing between a pair of stoppers 73 and 74 fixed at 0, and is stabilized in a state in which it is in contact with one of the stoppers 73 and 74 due to the biasing force of the spring 71. Further, when the rotary plate 69 is in contact with the stopper 73, the rotating body 63 is close to the position where the mount 2 and the label 3 of the peeling part 61 are separated, and when the rotary plate 69 is in contact with the stopper 74, It is sufficiently spaced from the peeling part 61. As shown in an enlarged view in FIG. 11, the rotary body 63, like the rotary body 33 described above, is located slightly below the plane that includes the traveling direction of the label 3 that is normally peeled off. shall be established.

Next, the operation of the above embodiment will be explained.

First, when loading the label strip 1, the rotary plate 6
This is done after the loading operation is facilitated by bringing the stopper 9 into contact with the stopper 74. When loading of the label band 1 is completed, the rotary plate 69 is brought into contact with the stopper 73 to bring the rotating body 63 close to the position where the mount 2 and the label 3 are separated. In this state, the following printing, transport, and label peeling operations are started.

The label strip 1 supplied from the supply section 51 is transferred intermittently by the transfer section 62 as appropriate. The printing unit 53 and the stamp unit 54 print variable data and fixed data, respectively, at predetermined positions on each label 3 during the intermittent transfer process.

Further, since the mount 2 pulled by the transfer section 62 is turned around at the peeling section 61, the printed label 3 is peeled off from the mount 2 due to its own rigidity. However, the label 3, which cannot be peeled off only by turning the backing paper 2, is turned together with the backing paper 2. In this way, the label 3 which is not completely peeled off and is in a turned state together with the mount 2, is reliably peeled off by having its tip end abutting the rotary body 63 and moving forward while rotating the rotary body 63. Ru.
During this peeling, the label 3 advances while in contact with the rotary body 63, and the rotary body 63 rotates in the traveling direction as the label 3 advances, as in the first embodiment described above. Therefore, the contact resistance of the label 3 with the rotating body 63 is extremely small, and the label 3 can be peeled off more smoothly.

Note that in the second embodiment, the rotating body 63
exemplified is a helical member rotatably wound around a pin 67 implanted in a rotating plate 69. However, this rotating body 63 is not replaced by the rollers 41 or rollers 43, 45, 4 as shown in FIGS. 5 to 8 of the first embodiment.
7, and these can be attached to the rotary plate 69 with an appropriate structure and operated.

As described above in each of the embodiments, the label peeling device according to the present invention includes a rotating body that is rotatably disposed in a position where the label and the mount are separated from each other in the peeling section by contacting the label, and Even labels that cannot be peeled off simply by turning the mount come into contact with this rotary body and are moved while rotating the rotary body, so that they can be reliably peeled off without resistance.
Therefore, even a label temporarily attached to a mount under adverse conditions can be reliably peeled off, thereby preventing machine failure due to label issuance errors or label jams.
