Description

  The present invention relates to a mountless label issuing apparatus that issues a mountless label, one side of which is a printing surface and the other side is a sticking surface formed of an adhesive layer.

A conventional mountless label issuing device includes a cutting means including a blade body having a substantially V-shaped blade portion when viewed from the front and a straight belt-like blade body, and the substantially V-shaped blade body and the straight belt-like blade body. A mountless label sheet is inserted between them, and the mountless label sheet is cut by driving the substantially V-shaped blade (see, for example, Patent Document 1).
And in the said patent document 1, by providing a non-adhesive coating film on a substantially V-shaped blade body, the adhesive of the adhesive layer of the mountless label paper or the adhesion of paper dust generated when the label paper is cut is attached. It is preventing. However, the coating process cannot sufficiently prevent adhesion of glue or the like.

  In the cutting means using a rotary blade, a technique has been proposed in which glue or the like is prevented from adhering to the blade by moving the rotary blade while making contact with the felt impregnated with silicon oil (for example, Patent Document 2).

Therefore, when the technique described in Patent Document 2 is applied to the cutting means of the blade body provided with the substantially V-shaped blade portion when viewed from the front, the following problem arises and cannot be applied.
(1) In Patent Document 2, since the blade tip is sandwiched and housed in a felt impregnated with oil, a shearing action by a pair of blades becomes impossible.
(2) Since the substantially V-shaped blade in Patent Document 1 contacts only the both sides of the linear oil-impregnated felt in Patent Document 2, an extra load (resistance) acts on the advancing / retreating operation, which is substantially omitted. It cannot be used for cutting means having a V-shaped blade body, and oil cannot be applied to a V-shaped blade body in a substantially front view.

JP 2000-190280 A Japanese Patent No. 4137210

  The present invention has been made in view of the above-described problems of the prior art, and in a mountless label issuing apparatus having a cutting means having a substantially V-shaped blade portion when viewed from the front, a load is imposed on the advancing and retreating operation of the blade body. In addition, an object of the present invention is to provide a mountless label issuing device that can prevent glue and paper dust from adhering to the blade body with a simple structure.

In order to achieve the above object, the mountless label issuing apparatus of the present invention is a mountless label issuing apparatus comprising a cutting means for cutting the mountless label paper by a shearing action, wherein the cutting means prints the mountless label paper . The mount-less label has a movable blade disposed on the surface side and a blade body formed in a substantially V shape in front view, and only in the vicinity of the deepest V portion of the blade body formed in a substantially V shape in front view. An oil holding body for applying oil to prevent the adhesive of the paper from adhering is provided, and a fixed blade arranged on the adhesive application surface side of the mountless label paper is provided.
The mountless label cutting unit of the present invention includes a movable blade disposed above the fixed blade, which will be described later, and disposed on the printing surface side of the mountless label sheet , and a blade body formed in a substantially V shape in front view. And an oil holding body for applying oil to prevent the adhesive of the mountless label paper from adhering only to the vicinity of the deepest V portion of the blade formed in a substantially V shape in front view. And a fixed blade disposed on the side of the adhesive surface of the label sheet .

Examples of the oil holder include a form in which oil is impregnated and held in an elastic impregnated body such as a sponge (for example, an open-cell foam), and a form in which oil is contained in a container. The oil is applied from the oil holding body to the blade body by a direct method in which the blade body (movable blade) is applied by directly contacting the oil holding body, or the blade body (movable blade) is moved back and forth. Any of the indirect methods in which oil is applied to the blade body by the action of another member to be linked may be used.
In addition, when the oil holder is an elastic impregnated body such as sponge, the oil can be applied to substantially the entire width of the blade body as long as the holder has substantially the same width as the blade body. When the body is a substantially V-shaped blade body as viewed from the front, the glue that adheres at the time of cutting gathers in the vicinity of the deepest part of the V part. It suffices if they are arranged at corresponding locations .

When the cutting means is a system in which only one blade body is driven, the oil holding body is attached to the side surface of the fixed blade on which the movable blade slides and within the moving region of the movable blade. Thereby, after the movable blade advances and cuts the label paper, the blade tip of the movable blade touches the oil holding body at the final stage of the advance, and the oil is applied to the blade body of the movable blade.
In addition, since the oil holding body is located on the surface of the fixed blade that the movable blade is in sliding contact with, the oil oozes out from the oil holding body by acting so that the cutting edge of the movable blade presses against the oil holding body. However, the oil that has oozed out adheres to the surface on which the movable blade of the fixed blade slides. Therefore, the oil comes on not only the movable blade but also the surface of the fixed blade that contacts the movable blade, so that it is possible to prevent glue and paper dust from adhering to both the fixed blade and the movable blade.

In the mountless label issuing device of the present invention, the oil is surely applied to the vicinity of the deepest V portion of the V-shaped cutting edge in front view by the forward / backward movement of the blade body. They can be prevented from adhering to the vicinity of the deepest V portion of the V-shaped cutting edge.
In addition, by attaching the oil holder to the fixed blade, the oil holder can be attached stably, and not only the movable blade but also the surface of the fixed blade in contact with the movable blade can be reliably moved by the forward and backward movement of the movable blade. Oil can be applied to both the fixed blade and the movable blade, and adhesion of glue and paper dust can be prevented.

The side view which shows the outline of the mountless label issuing apparatus which concerns on a reference example . It is an enlarged view of a cutting | disconnection means, (a) is a front view, (b) is the longitudinal cross-sectional side view. The front view which shows the modification of the oil holding body attached to a cutting | disconnection means. The cutting means and oil holding body which concern on embodiment of this invention are shown, (a) is a front view, (b) is the longitudinal cross-sectional side view.

A reference example and an example of an embodiment of a mountless label issuing apparatus according to the present invention will be described with reference to the drawings.
FIG. 1 shows an outline of a mountless label issuing apparatus A according to a reference example . A roll loading unit 2 is provided in a case 1, and a label sheet of a mountless label roll set in the roll loading unit 2 is fed forward. At the position, a label sheet feeding means 3, a printing unit 4, and a cutting means 5 for cutting the printed mountless label paper to a predetermined length are arranged, and the cutting means 5 is provided with an oil holder 6. Further, a label holding unit 7 for temporarily holding the mountless label L cut and sent is provided in front of the cutting means 5. A mountless label roll 8 is rotatably supported by the roll loading unit 2.

  The sending means 3 for sending the label paper 8 ′ from the mountless label roll 8 includes a downstream paper sending means 3b composed of a pair of upper and lower rollers arranged in the vicinity of the upstream side of the label outlet 9 provided on the peripheral wall of the case 1. The upstream sheet delivery means 3a also serves as the printing unit 4 disposed at a predetermined interval upstream of the sheet delivery means 3b.

  The upstream sheet delivery means 3a that also serves as the printing unit 4 includes a platen roller 4a positioned below (labeling side) the label sheet 8 'and a thermal head positioned above (printing side) the label sheet 8'. 4b, and the platen roller 4a and the lower roller of the downstream sheet feeding means 3b are driven and rotated by a motor. The thermal head 4b positioned above the label paper 8 'and the upper roller in the downstream paper feed means 3b are respectively connected to the label paper 8' as a lower roller (lower roller and platen roller in the paper feed means 3b). 4a), the label paper 8 'is urged downward so as to be attached, so that the label paper 8' can be sent out stably.

  Further, the platen roller 4a of the printing unit 4 and the lower roller of the downstream paper feeding means 3b are coated with a release agent on the respective surfaces, and are applied to the side opposite to the printing surface of the label paper 8 '. The attached adhesive is prevented from adhering so that the label paper 8 'can be fed smoothly. The configuration in which the adhesive layer of the label paper 8 ′ is less likely to adhere to the roller is not limited to the above configuration, and the roller itself or the outermost peripheral portion of the roller may be configured with an easily peelable member.

  The cutting means 5 for cutting the label paper 8 ′ printed on the product information printed by the printing unit 4 and sent to the label delivery port 9 into sheets of a predetermined length is sent horizontally from the label delivery port 9. It is composed of a pair of upper and lower fixed blades 5a and a movable blade 5b arranged so as to sandwich the label paper 8 '.

  The fixed blade 5a disposed on the printing surface side (upper side) of the label paper 8 ′ is formed of a band blade having a blade edge formed in a straight line with the same width, and is disposed on the sticking surface side (lower side) of the label paper 8 ′. The movable blade 5b has a substantially V-shaped blade portion when viewed from the front, and the label paper 8 'is cut by a shearing action as the movable blade 5b advances and retreats with respect to the fixed blade 5a. The movable blade 5b is configured to advance and retract by a motor (not shown).

An oil holding body 6 is attached to a side surface of the fixed blade 5a where the movable blade 5b is slidably contacted and in a moving region of the movable blade 5b. The oil holding body 6 comes into contact, and oil is applied to the cutting edge of the movable blade 5b, so that the adhesive of the label paper 8 'or paper dust generated by cutting the label paper 8' does not adhere to the movable blade 5b. It is like that.
That is, the movable blade 5b moves to a position where the blade edge slightly bites into the oil holding body 6, so that the oil oozes out from the oil holding body 6, and the oozed oil is applied to the cutting edge of the movable blade 5b. Is done.
Further, since the oil holding body 6 is located on the surface of the fixed blade 5a on which the movable blade 5b is slidably contacted, as described above, the cutting edge of the movable blade 5b acts so as to bite into the oil holding body. However, the oil is slightly oozed out from the oil holding body 6, and the oozed out oil also adheres to the surface of the fixed blade 5 a where the movable blade 5 b comes into sliding contact. Therefore, it is possible to prevent glue and paper dust from adhering not only to the movable blade 5b but also to the side surface of the blade edge of the fixed blade 5a. Further, the paper dust and glue of the cut label paper act so as not to adhere to the fixed blade 5a and the movable blade 5b, and act to adhere to the adhesive surface of the issued label.

The oil holding body 6 is obtained by impregnating an elastic body 6a such as a sponge of an open cell foam with 100% silicone oil 6b which is a food additive that does not adversely affect the human body even if it touches the human body. As shown in FIG. 2A, the elastic body 6a is formed in a substantially V shape (mountain shape) in which a surface corresponding to a substantially V-shaped cutting edge of the movable blade 5b meshes with a substantially V-shaped blade shape. Yes.
The elastic body 6a such as sponge impregnated with the oil 6b can be attached to the fixed blade 5a by either fixing with an adhesive or attaching a storage frame to the fixed blade 5a and storing the elastic body 6a in the storage frame. Good. When the elastic body 6a is fixed to the fixed blade 5a by bonding, the region where the movable blade 5b enters the elastic body 6a is not bonded, and the movable blade 5b smoothly enters the elastic body 6a.

Further, the elastic body 6a such as a sponge impregnated with the oil 6b constituting the oil holding body 6 is a label sheet 8 cut by a shearing action when the movable blade 5b is a blade body having a substantially V-shaped blade edge when viewed from the front. The 'adhesive is brought to the deepest part (valley part) of the V part of the substantially V-shaped cutting edge. For this reason, the adhesive of the label paper 8 ′ is likely to adhere to the vicinity of the deepest V portion of the substantially V-shaped front view of the movable blade 5b, so that the elastic body 6a of the oil holding body 6 has the blade width of the movable blade 5b. As shown in FIG. 3, the elastic body 6a ′ having a small width corresponding to the portion near the deepest V portion of the substantially V-shaped cutting edge of the movable blade 5b, as shown in FIG. 3, without having the substantially same width (see FIG. 2A). It is good.
As described above, by providing the elastic body 6a impregnated with the oil 6b so as to fit the shape of the substantially V-shaped blade portion when viewed from the front, the sheet is caused by the shearing action between the movable blade 5b and the fixed blade 5a when viewed from the front. Even when cutting, oil is reliably applied in the vicinity of the deepest V portion of the V-shaped cutting edge when viewed from the front, so that it is possible to prevent glue or paper dust from adhering to the portion. Further, since the shape of the movable blade 5b and the elastic body 6a impregnated with the oil 6b are matched, there is no load when the movable blade 5b is moved.
Further, by making the blade portion of the movable blade 5b substantially V-shaped when viewed from the front, the label paper 8 ′ is cut from the both sides in the width direction toward the center, so that the movable blade 5b moves. The distance can be reduced. Thereby, the cutting means 5 can be made into a compact unit.

  The label holding unit 7 that temporarily holds the mountless label L cut by the cutting means 5 in a standby state has a frame body 7b having a abacus ball-shaped contact member 7a, and a fixed frame 10 on the outer surface of the case 1. Installed. The mountless label L delivered to the label holding unit 7 is pasted on the product by automatic pasting by an pasting means (applicator) or by manual pasting by an operator.

In the previous reference example (see FIGS. 2 and 3), the straight band-shaped blade body is the fixed blade 5a, the blade body having a substantially V-shaped blade portion in front view is the movable blade 5b, and the oil retaining body 6 is attached to the fixed blade 5a. However, it may be reversed.
FIG. 4 is a view showing a cutting means and an oil holding body according to the embodiment of the present invention.
The cutting means 11 shown in FIG. 4 has a band blade having a blade portion formed in a straight line with the same width as the movable blade 11a on the printing surface side (upper side) of the label paper 8 ′, and affixing the label paper 8 ′. On the surface side (downward), the blade portion is formed in a substantially V shape as a fixed blade 11b and a blade body is disposed, and the movable blade 11a moves forward and backward with respect to the fixed blade 11b, whereby the label paper 8 ' It is cut by the shearing action. An oil holding body 12 (an elastic body such as a sponge impregnated with oil) is bonded and fixed to a surface (back surface) of the fixed blade 11b on which the movable blade 11a comes into sliding contact. In this case, since the movable blade 11a is a band blade, the elastic body of the oil holding body 12 has substantially the same width as the lateral width of the movable blade 11a so that the entire blade portion of the movable blade 11a is in contact with the elastic body together. It is formed in a rectangular shape.
And by the said structure, oil is apply | coated to the back surface of the fixed blade 11b of front view substantially V shape by sliding contact of the movable blade 11a, and paste, paper dust, etc. adhere to the back surface of the fixed blade 11b of front view substantially V shape. Can be prevented. Further, since the oil holding body 12 is attached to the fixed blade 11b disposed on the sticking surface side of the label paper 8 ′, the oil that has oozed out by contact with the oil holding body 12 due to the advancement (downward movement) of the movable blade 11a. Is applied in sliding contact with the back surface of the fixed blade as the movable blade 11a retreats (ascends), but the applied oil hangs down along the back surface of the fixed blade due to gravity and is absorbed by the oil holder 12. Therefore, it is possible to prevent the oil from dripping drastically.

  The mountless label issuing apparatus configured as described above can cut and form a sheet-like mountless label having a predetermined length from the label sheet by the shearing action of the movable blade and the fixed blade constituting the cutting means. And, since an elastic body (oil holding body) such as a sponge impregnated with oil is attached to the surface in which the movable blade of the fixed blade constituting the cutting means is in sliding contact and in the moving region of the movable blade, Due to the movement of the movable blade after the movable blade has cut the label paper by the shearing action between the movable blade and the fixed blade, the blade portion of the movable blade comes into contact with the sponge impregnated with oil, and the blade portion is coated with oil. . Further, when the movable blade comes into contact with the sponge, the oil impregnated in the sponge oozes out and attaches to the back surface of the fixed blade (the surface opposite to the surface on which the blade is formed). And the back surface of the movable blade (surface opposite to the surface on which the blade is formed) are in sliding contact with each other, so that oil is applied to the back surface of the movable blade as a result. Thereby, when the label paper is cut, the adhesive (glue) of the label paper and paper dust generated by the cutting are prevented from adhering to the movable blade and the fixed blade.

The present invention is not limited to the illustrated embodiment, and can be appropriately changed without departing from the gist of the present invention.
(1) In the embodiment, the cutting means is composed of a straight band blade and a substantially V-shaped blade body in a front view, and one blade body is a fixed blade and the other blade body is a movable blade. It is not limited to this, For example, the form which uses both blade bodies as a movable blade, or the form which comprises a pair of upper and lower blade bodies with a substantially V-shaped blade body in front view, etc. may be sufficient.
(2) In the embodiment, the configuration in which the elastic body (sponge) of the oil holding body is adhered to the fixed blade in an exposed state is shown, but the present invention is not limited thereto. For example, a pocket-shaped storage portion is provided on the fixed blade, You may accommodate the elastic body of an oil holding body in the accommodating part.
(3) In the embodiment, the mode of supporting the attachment surface side of the mountless label as the label holding unit for temporarily holding the mountless label to be cut and sent is not limited to this.
