Description

[Detailed description of the invention] (Field of application of the invention) The present invention is designed to remove the labels from the mount by turning the mount of a label band, which is made up of a plurality of labels temporarily attached to a band-shaped mount, in a label peeling section. The present invention relates to a label peeling device for peeling a label, and particularly to a device configured to peel a label more reliably.

(Prior Art) This type of label peeling device is widely employed in label printing and pasting machines, metering printers, or other label issuing machines. However, in order to manufacture the entire label strip at low cost, it is necessary to use labels and mounts made of inexpensive coarse paper materials;
Alternatively, attempts have been made to apply a release agent thinly and roughly to the side of the mount to which the label is temporarily attached so that the label can be easily peeled off from the mount. For this reason,
The label itself has little rigidity, and the backing paper has a rough texture, so the release agent soaks into the backing paper, making it 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 does not peel off from the backing paper in this way, not only will the label not be issued, but the label will stick to the backing paper transport path, making the machine unable to operate or causing a malfunction. .

As an improvement over such inconveniences, there is a "portable labeling device" described in Japanese Patent Application Laid-Open No. 1342/1983, filed by the same applicant. In this prior application, "a peeling auxiliary member is provided in a position close to the place where the backing paper turns and in front of the label in the traveling direction," and this peeling auxiliary member basically performs its peeling action. Since the peeling force is applied uniformly in the width direction of the label, the peeling force does not necessarily act as a strong force, and the same problems as described above may occur.

(Purpose of the invention) The present invention was made in view of the above points, and it can be used reliably even with label strips that are manufactured at low cost and have uneven temporary adhesion strength between the label and the mount as described above. An object of the present invention is to provide a label peeling device that can peel a label from a mount.

(Summary of the invention) In order to achieve this purpose, in the present invention, at the position where the mount and label are separated near the peeling part,
A rotating body is provided with a label contacting part on the outer periphery of the side on which the adhesive of the label is applied, and even labels that cannot be peeled off simply by turning the mount can be rotated by contacting the label contacting part of this rotating body. It is configured so that it can be removed reliably without resistance by advancing while rotating the body. Furthermore, the label abutting part of the rotating body has a large diameter at the part corresponding to the central part of the label, which curves the label during peeling and strengthens its own rigidity. The center part is first peeled off from the backing paper, and the peeling phenomenon is spread to an external force in the width direction of the label (towards both ends) and to the rear of the label, thereby ensuring that the entire label is peeled off from the backing paper. be.

(Embodiments) 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 label supply section 22 is supplied to the label peeling device 23. This label peeling device 23 includes a transfer section 24 that transfers the label strip 1 as appropriate.
and the label band 1 near the front lower end of the main body 11.
A peeling part 30 peels off the label 3 from the mount 2 by turning only the mount 2 of the label 3 itself, and the peeling part 30 is disposed close to the position where the mount 2 and the label 3 are separated. A rotary body 33 is provided, which is the gist of the present invention.

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.
As the other end engages with the engagement pin 26b, the transfer drum 26 is rotated as the actuating lever 15 reciprocates.
The label band 1 is transported by rotating the label band 1 appropriately. A spring 29 biases the hook 27 toward the engagement pin 26b.

As shown in FIGS. 2 and 3, the main body 11 has both side edges 35a, 35b and these side edges 35a, 35.
The bottom cover 35 includes a connecting portion 35c that connects the bottom lid 35c. 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.

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.
A platen 39, which will be described later, is located between 32, the label band 1 is inserted between the regulating member 31 and the platen 39, and only the mount 2 is turned between the platen 39 and the regulating member 32.
Each label 3 is peeled off from the mount 2 due to its own rigidity.

A pin 36 is rotatably provided between both side edges 35a and 35b of the bottom cover 35 at a position near the peeling part 30 where the mount 2 and the label 3 are separated, as shown in FIG. The rotating body 33 is rotatably supported by this pin 36. On the outer periphery of the rotating body 33, a plurality of annular protrusions 33a are provided at predetermined intervals in the axial direction, forming a label abutting portion for the side of the label 3 on which the adhesive 5 is applied. There is. These protrusions 33a are
Portions corresponding to both ends of the label 3 have a small diameter, and the diameter gradually increases as the portion corresponds to the center of the label 3. It is more preferable that a silicone resin or the like be applied to the protrusion 33a of 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 sticking roller for sticking the label 3 sent out from the label sending window 35d formed in the bottom cover 35 onto an article, etc., and is rotatably supported by a pivot shaft 34. Furthermore, 49 is a temporary holding piece for temporarily holding the peeled label 3.

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

First, the bottom cover 35 of the main body 11 is opened, and the lower regulating member 32, the rotating body 33 supported by the pin 36, and the guide member 38 are separated from the passage of the label band 1 and the mount 2 to facilitate insertion. Do that loading. Note that during this loading, the guide member 37 is moved toward and away from the transfer drum 26. When the hand lever 13 is grasped after the loading is finished and the lower lid 35 is closed, the hand lever 13 and the operating lever 15 are rotated counterclockwise (FIG. 2) against the biasing force of the return spring 21. move. As the operating lever 15 rotates, the printing device 16 descends, and the selected characters 17a of each printing wheel 17 are coated with ink by the ink roller 18, and then printed on the label 3 on the platen 38.

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 temporary holding piece 49 until it is pasted onto an article or the like by the pasting roller 40.

However, since the backing paper 2 is turned in the peeling section 30, not all the labels 3 are necessarily removed from the backing paper 2.
It does not necessarily mean that it will be peeled off. That is, depending on the material of the label 3, the rigidity may be weak, and depending on the quality and application state of the release agent 4 and adhesive 5 applied to the mount 2 and the label 3, respectively, the mount 2 may have low rigidity.
In some cases, the label 3 is temporarily attached more strongly than necessary. Under these conditions, the labels 3 of the label band 1 will not be completely peeled off from the mount 2, and the mount 2 will not be completely peeled off.
Conversions occur frequently.

In view of the above points, in the present invention, the rotating body 33 is located close to the position where the mount 2 and the label 3 are separated.
is provided. Therefore, even if the label 3 is not completely peeled off from the backing paper 2 and is turned along with the backing paper 2, the vicinity of the tip on the side where the adhesive 5 is applied is the ridge 33a of the rotating body 33, as shown in FIG. By coming into contact with and moving forward while rotating the rotating body 33, it is reliably peeled off. During this peeling, the label 3 turns while contacting each protrusion 33a of the rotary body 33, but the rotary body 33 itself rotates in the direction of travel as the label 3 advances. 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.

Further, the ring-shaped protrusion 33a provided on the rotating body 33 has a diameter that gradually increases as it approaches the center of the label 3. For this reason, the label 3 that is being peeled off when in contact with the rotating body 33 is curved as shown in FIG. 3, and its rigidity is strengthened, so that peeling becomes more reliable. Furthermore, the central part of the label 3, which requires the strongest peeling force, is first peeled off from the mount 2, and the peeling phenomenon is
The external force in the width direction (in both end directions) is applied to the rear of the label 3 to ensure that the entire label 3 is peeled off from the mount 2. 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, for example, if the tip of the platen 39 is
0, and the mount 2 can be hung around the tip of the platen 39 and turned. 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 connected to the bottom cover 35 by a pin 36.
This example illustrates a configuration in which the bottom cover 35 is opened to separate the rotating body 33 from the path of the label strip 1 when the label strip 1 is loaded, thereby facilitating the loading. However, if the front or side surfaces of the main body 11 are opened and closed when the label strip 1 is loaded, the rotating body 33 can be attached to those opening/closing portions, or the loading of the label strip 1 can be facilitated by other means. For example, the rotating body 33 can be supported on a portion of the main body 11 that does not open or close.

Furthermore, in the above embodiment, the pin 36 is rotatably supported, and the label 3 is attached to the outer periphery.
Although a rotating body is illustrated in which a protrusion 33a is formed that gradually increases in diameter as it corresponds to the center,
This rotating body can also be constructed, for example, as shown in FIGS. 5 to 8, respectively. That is, the example shown in FIG. 5 has a configuration in which three rotating bodies 41 are rotatably supported by pins 42, and a label abutting portion formed on the outer peripheral surface of the central rotating body 41 is configured. The diameter of the annular tube-shaped protrusion 41a is larger than the diameter of the protrusion 41a formed on the rotating body 41 on both sides. Further, the rotating body 43 shown in FIG. 6 is composed of a required number of rollers rotatably supported by a pin 44, and the outer circumferential portion 43a of these rotating bodies 43, which constitutes the label abutting part, is in contact with the label 3. Pointed to reduce contact area. The diameter of the outer peripheral portion 43a of the rotating body 43 located near the center is
Outer peripheral portion 43a of rotating body 43 located near both sides
The diameter is larger than that of the The rotating body 45 shown in FIG. 7 is composed of a roller formed integrally with a rotatable shaft 46, and has a large number of protrusions 45a forming a label abutting portion formed on its outer peripheral surface. The height of these protrusions 45a gradually increases toward the center of the rotating body 45, and as a result, in the group of protrusions 45a that constitute the label abutting part, the part corresponding to the center of the rotating body 45 is Large diameter. The example of the rotary body 47 shown in FIG. 8 has the simplest configuration consisting of a roller integrally formed with a rotatable shaft 48, and the outer circumferential surface 47a of the rotary body 47 itself constitutes the label abutting portion. There is. The rotating body 47 is formed to have a diameter that gradually increases from both sides toward the center.

Next, a second embodiment of the present invention will be described with reference to FIGS. 9 to 11. This embodiment is an example in which the label peeling device according to the present invention is applied to a thermal transfer type printer, and is particularly suitable for peeling off large labels attached to items such as cardboard boxes. It is.

is pressed against the platen roller 51 by this urging force. A driven roller 57 is pivotally connected to the head support 53, and is pressed against the platen roller 51 by the biasing force mentioned above.

A label supply section 60 is disposed in the main body 50, and this label supply section 60 winds and holds a label strip 1 as shown in FIG. After the label strip 1 supplied from the label supply section 60 passes between the platen roller 51, the thermal head 55, and the driven roller 57, only the backing paper 2 is turned by the turning pin 70 that constitutes the label peeling section. This allows the label 3 to be peeled off from the mount 2. The mount 2 with the label 3 peeled off is appropriately wound up by a mount winding section 61 driven by a pulse motor PM via a belt 79.

Further, the main body 50 is provided with a ribbon supply section 63 in which a thermal transfer ribbon 62 is wound and held.
Ribbon 62 supplied from this ribbon supply section 63
is overlapped with label band 1 and platen roller 5
After passing between the belt 80 and the thermal head 55 and the driven roller 57, the belt 80 is moved by the pulse motor PM.
The ribbon winding section 64 is configured to appropriately wind the ribbon into a ribbon winding section 64 which is driven via the ribbon winding section 64 . 65, 66, 6
Reference numerals 7, 68, and 69 are guide rollers that appropriately guide the label strip 1, the mount 2, the thermal transfer ribbon 62, etc., and 71 is a guide plate that guides the mount 2.

Above the main body 50, the lid body 72 has a pair of hinges 73.
It is provided so that it can be opened and closed by. This lid body 7
10 and 11, a pair of support members 74 and 75 are fixed to the inner surface of one side of 2 by screws, and these support members 74,
Both ends of a pin 76 are rotatably attached to the pin 75 . Further, this pin 76 rotatably supports a rotating body 77 having an annular protrusion 77a on its outer periphery that constitutes a label abutting portion. A large number of the protrusions 77a are provided along the axial direction of the rotating body 77, and their diameters gradually increase toward the center of the rotating body 77, that is, the position corresponding to the center of the label 3. There is. The rotary body 77 configured in this manner is arranged so that when the lid body 72 is closed, the mount 2 near the turning pin 70 that constitutes the label peeling part is rotated.
The cover body 72 is located at the part where the label 3 and the label 3 are separated.
When the turning pin 7 opens, the turning pin 7 rotates as the lid body 72 opens.

As mentioned above, the label peeling device in the second embodiment includes a pulse motor PM, a platen roller 5
1, a transfer section consisting of a driven roller 57, a label winding section 61, and a ribbon winding section 64; a turning pin 70 forming a label peeling section; and a rotating body 77, which is the gist of the present invention.

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

The label band 1 supplied from the label supply section 60 and the thermal transfer ribbon 62 supplied from the ribbon supply section 63 are superimposed on each other at the position of the guide roller 66, and then transferred to the platen roller 51, the thermal head 55, and the driven roller 57. pass between. These label band 1 and thermal transfer ribbon 62 are transported while being sandwiched between a platen roller 51 and a driven roller 57, which are driven intermittently by a pulse motor PM. During this transfer, the heat generating part 55 of the thermal head 55 is moved based on the information to be printed.
Desired information is printed on the label 3 of the label band 1 by appropriately driving the a. The part of the backing paper 2 of the label band 1 on which the printing is done on the label 3 is turned approximately at a right angle by the turning pin 70, and then wound up by the backing paper winding section 61. Due to this turning of the mount 2, the label 3 is peeled off from the mount 2 due to its own rigidity, but the label 3, which cannot be peeled off only by the turning of the mount 2, is turned together with the mount 2. As shown in FIG. 11, the label 3, which is not completely peeled off and is in a turned state together with the mount 2, is reliably removed by abutting each protrusion 77a and moving while rotating the rotating body 77. It will be peeled off. In addition, the rotating body 77 protrusion 77 in this embodiment
a has a diameter that gradually increases toward the center of the label 3, that is, the center of the rotating body 77, so that the label 3 is
By curving the label 3, the rigidity of the label 3 is made stronger, and the central part of the label 3, which requires the strongest peeling force, is moved further away from the mount 2. It spreads to the external force in the direction (both end directions) and to the rear of the label 3. Therefore, the label 3 which cannot be completely peeled off from the mount 2 can be peeled off more reliably by the above-described configuration of the rotating body 77.

Note that in the second embodiment, the rotating body 77
is rotatably supported by a pin 76, and has a number of protrusions 7 on its outer periphery that gradually increase in diameter toward the center.
7a is shown as an example. However, this rotating body 77 may have a configuration as shown in FIGS. 5 to 8 of the first embodiment described above.

(Effects) As explained above in each embodiment, in the label peeling device according to the present invention, the rotary body having the label abutting part on the outer periphery is disposed at a position near the peeling part where the backing paper and the label are separated, and the backing paper Even a label that cannot be peeled off simply by turning the rotary body is configured to come into contact with the label abutting portion of the rotary body and move forward while rotating the rotary body, so that the label can be surely peeled off without resistance. Furthermore, the label abutting part of the rotating body has a large diameter at the part corresponding to the center of the label, which strengthens its rigidity by curving the abutted label, and requires the strongest peeling force. First, the center part of the label is peeled off from the label, and the peeling phenomenon is controlled by external force in the width direction of the label (toward both ends).
This spreads to the back of the label and makes it easy to separate the entire label from the mount. 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.
