[0002]
[Prior art]
2. Description of the Related Art Conventionally, an integrated form in which unit forms are connected via a cutting machine and a plurality of stacked sheets are bonded and integrated so as to be peeled off is used for a delivery slip or the like.
These integrated foams are usually stacked while transporting a plurality of continuous sheets, bonded and integrated so that they can be peeled off, and then the cutting machine blade is pressed from one direction so that the cutting machine is applied to a predetermined location. Let it form.
[0003]
In this case, as shown in FIG. 8, when the cutting machine blade 41 is passed through the conventional integrated form 40, the cutting machine blade 41 is pushed out to the back side of the paper 42 at the position where the cutting machine blade 41 is finally passed through. As a result, a so-called burr 43 caused by the rising of the sheet is generated around the penetrating portion of the sheet 42.
The raised portion due to the paper cut is referred to as a burr here, but the burr is generated in the paper, and the paper surface is not flat. is there.
[0004]
For example, if a conventional integrated form is adapted to a delivery slip sheet, a plurality of unit forms are connected via a cutting machine, and each unit form is separated and used as a delivery slip by cutting from the cutting machine. It is configured. (For example, Reference 1)
When using this integrated form, the unit form is connected with a cutting machine, and after shipping information such as a delivery destination is printed with a laser printer, the unit is cut from the sewing machine with a burster. It is cut and separated into a foam, and is used by sticking to a delivery item with an adhesive layer.
[0005]
Normally, these processes are carried out with unit foams connected by a cutting machine, printed with a laser printer while transporting continuous unit forms of an integrated form, or cut from a sewing machine with a burster, etc. Processing is performed by performing cut processing every time.
However, if there is a burr 43 on the surface of the integrated foam, there is a problem that the burr 43 is caught and becomes an obstacle during conveyance.

A half cut 6 is formed between the delivery slip 3 and the sticking slip 4.
[0014]
Next, the structure of the integrated foam 1 will be described with reference to FIGS.
The integrated foam 1 includes a label base material 7 having a release paper 9 attached to an adhesive layer 8 applied to the back surface, and a delivery slip 3 and a sticker slip 4 attached on the label base material 7. And a slip sheet 20.
The slip sheet 20 stuck on the label base material 7 has the delivery slip 3 pasted on the label base material 7 via the release layer 10 and the pseudo adhesive layer 11 at the portion that becomes the delivery slip 3. The sticking slip 4 is stuck on the label base material 7 via the pseudo adhesive layer 11 in the portion to be the sticking slip 4.
As shown in the figure, the release layer 10 and the pseudo adhesive layer 11 may be laminated on the label base material 7 in order, or the pseudo adhesive layer 11 may be laminated on the label base material 7 in sequence. 11 and the release layer 10 may be sequentially laminated.
[0015]
Moreover, as shown in FIG. 4, since the half cut 6 is formed between the delivery slip 3 and the sticking slip 4, the end portion of the delivery slip 3 is picked while the half cut 6 is bent. The delivery slip 3 can be peeled off from the label base material 7 by pulling, and the sticking slip 4 is stuck to the label base material 7 only by the pseudo adhesive layer 11. It is configured so that it cannot be peeled off.
[0016]
A unit form comprising three delivery slips 2 is connected to the integrated form 1 via a cut-off sewing machine 5, and each of the cut-off sewing machines 5 is formed from the front and back sides of the integrated form 1. 1 has a structure that is cut and drilled in the inner surface direction.
In other words, the cut-off sewing machine 5 formed on the slip sheet 20 positioned at the top of the integrated form 1 has a perforated portion cut downward from the upper surface of the slip sheet 20, and the adhesive layer 8. The label base material 7 and the release paper 9 attached by the above have a perforated portion cut upward from the lower surface of the release paper 9 positioned at the lowest position of the integrated foam 1.
For this reason, as shown in FIG. 3, burrs 12 generated when the cut-off sewing machine 5 is formed do not occur on the front and back sides of the integrated form 1, and these plural sheets are stacked inside. It is configured to be hidden.
[0017]
The slip paper 20 can be used as long as it has sufficient strength, printability by a printer, and transportability. For example, high-quality paper, kraft paper, copy paper, glassine paper, parchment paper, rayon paper, coated paper, synthetic paper Paper such as paper and paper laminated with a resin film is preferably used, but resin films such as cellophane, stretched polypropylene, polyethylene terephthalate, stretched polystyrene, and polyvinyl chloride may also be used.
As for the thickness of a display base material, about 20-200 micrometers is preferable normally.
Also, the label base material 7 can use the same paper or film as the slip sheet 20.
[0018]
The pseudo-adhesion layer 11 is for integrating the label base material 7 and the slip sheet 20, and for example, urethane-based, acrylic-based thermoplastic resins can be used, such as a flexo method and a gravure method. It is applied to a thickness of about 0.1 to 50 μm by a known printing method or coating method, and is dried as necessary after bonding. The label base material 7 and the slip sheet 20 are bonded together by a wet or semi-wet laminating method, a thermocompression bonding method, or a pressure sensitive method in which the adhesive (or resin) is not dried.
[0019]
As the release layer 10, it is preferable to use a resin having low adhesion so that the delivery slip 3 can be easily peeled off from the label substrate 7, and an olefinic (co) polymer such as polyethylene, polypropylene, polybutylene or the like is used. In addition, other thermoplastic resins such as polystyrene, polyvinyl butyral, vinyl acetate copolymer, ethylene-vinyl acetate copolymer, vinyl chloride-vinyl acetate copolymer, acrylic resin, cellulose resin, and the like A film made of a mixture may be used.
Moreover, you may use the film formed from thermosetting resins, such as a polyurethane.
Furthermore, an antioxidant, a heat stabilizer, an ultraviolet absorber, a slip agent, an antistatic agent, an antifogging agent, a colorant, a filler, and the like may be added as desired.
Although the application amount and application thickness of the resin for forming the release layer 10 are not particularly limited, the application amount is preferably 0.1 to 10 μm.
[0020]
The pressure-sensitive adhesive layer 8 is a layer that enables the delivery slip 2 to be affixed to a package and is most preferably an acrylic pressure-sensitive adhesive, but may be a natural rubber-based pressure-sensitive adhesive, a synthetic rubber-based pressure-sensitive adhesive, a silicone rubber-based pressure-sensitive adhesive, or the like.
The coating amount and coating thickness of the pressure-sensitive adhesive for forming the pressure-sensitive adhesive layer 8 are not particularly limited, but preferably the coating amount is 0.1 to 50 g / m ² and the coating thickness is 0.1 to 50 μm. .
[0021]
The adhesive force of the pressure-sensitive adhesive layer 8 to an adherend such as a baggage needs to be larger than the adhesive force between the pseudo-adhesive layer 11 and the release layer 10, and can be adjusted appropriately according to the adherend such as the baggage. is necessary.
Further, the adhesive force between the release paper 9 and the pressure-sensitive adhesive layer 8 is smaller than the adhesive force between the pseudo adhesive layer 11 and the release layer 10 in order not to release the pseudo adhesive layer 11 and the release layer 10 when handling the delivery slip. There is a need.
[0022]
Next, an embodiment of a method for manufacturing an integrated foam according to the present invention will be described. FIG. 5 shows a schematic view of a part of the steps in the case of manufacturing the integrated form with continuous paper.
In the illustrated process, a manufacturing process is provided in which two horizontal sewing devices 30 and 31, one vertical half-cut device 32, and one pseudo adhesive layer forming device 33 are provided.
It is assumed that desired printing is performed on the upper surface of the slip sheet 20 in a step before the illustrated step.

Further, the other horizontal sewing machine 31 has a state in which the label base material 7 and the release paper 9 in a continuous state are pasted through the adhesive layer 8 and the release layer is applied to the surface of the label base material 7. A continuous sewing machine 36 is provided with a horizontal sewing machine blade cylinder 31a and a sewing machine blade receiving cylinder 31b that are opposed to each other.
However, the horizontal sewing machine 31 is configured in such a manner that the sewing machine blade cylinder 31a is positioned on the lower side and the sewing machine blade receiving cylinder 31b is positioned on the upper side, and is continuously cut by cutting from the lower surface side of the continuous paper 36 with the sewing machine blade 37. Burr is not generated on the lower surface side of the sheet 36.
In other words, burrs are not generated on the outer surface side of the release paper 9 attached to the bottom of the continuous paper 36.
[0025]
Then, the slip sheet 20 and the continuous sheet 36 in a continuous state are conveyed to a pair of pressure rollers 38a and 38b, and the slip sheet 20 is superimposed on the upper side of the continuous sheet 36 as shown in FIG. The continuous paper 36 is adhered by the thermoplastic resin applied to the back surface of the sheet, and a continuous integrated foam is formed.
The uppermost sheet in the continuous integrated form is the delivery slip 20, and the lowermost sheet is the release sheet 9.
[0026]
Thereafter, the continuous integrated foam is conveyed to the vertical half-cut device 32.
The vertical half-cut device 32 has a half-cut blade cylinder 32a arranged on the upper side and a receiving cylinder 32b arranged on the lower side, sandwiching the continuous integrated form, and cutting the slip sheet 20 from the upper side of the integrated form. A half cut is formed.
As shown in FIG. 7, the continuous integrated form formed in this way is then overlaid with the unit form on which the delivery slip 2 is three-faced cut and folded back by a sewing machine, and is used by the printer during use. It is used by performing a printing process, or by performing a printing process with a printer after separating into unit forms before performing a printing process with a printer.
In the continuous integrated foam shown in FIG. 7, the feed holes 39 for conveyance are formed at regular intervals on both sides, but when used, the portions of the feed holes 39 are separated and used.
[0027]
Further, if necessary, the continuous integrated form is separated from the desired cut-off sewing machine 5 into a sheet-like integrated form that is three-sided with a burster or the like, and then the sheet-like integrated form is attached to the printer. You may make it perform necessary printing, such as applying.
[0028]

Even when printing, or cutting out each unit form from a cutting machine with a burster, etc., there is no risk of transport failure without being caught by burrs formed on the surface of the integrated foam during transport. effective.
In addition, since multiple stacked sheets of integrated form are stacked in the order of slip sheet, label base material, and release paper from the upper side, a large amount of processing can be performed even when adapted to delivery slips. It can be performed mechanically smoothly.
Further, in the integrated foam manufacturing method of the present invention, the uppermost sheet is cut from the upper surface side of the sheet and cut with a sewing blade, and the lowermost sheet is cut on the lower surface side of the sheet. Since it is formed by cutting with a sewing machine blade, burrs due to cutting do not occur on the outside, so even when printing with a laser printer or processing with a burster, etc., it prevents conveyance troubles caused by burrs. There is an effect that an integrated foam can be manufactured.
In addition, by using the uppermost sheet as a delivery slip and the lower sheet as a release sheet, an integrated form suitable for the delivery slip can be manufactured.
