Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanism capable of bonding both sheets by inserting a double-sided pressure-sensitive adhesive tape between a sheet-like object to be stuck and an object to be stuck, and a mechanism which enables the two to be stuck together. It relates to a special double-sided adhesive tape to be used.

[0002]

2. Description of the Related Art When a paper sheet is attached to an object to be attached such as a mount or a wall surface, when a single-sided or double-sided adhesive tape is used,
Generally, a method is used in which an adhesive tape is cut into an appropriate length in advance, and then the tape is directly held by hand and attached.

[0003]

In order to attach a paper sheet to an object to be attached, such as when attaching a scrap of a photograph, a figure, or a newspaper article to a mount, a double-sided adhesive tape has been used more often than a glue in recent years. . At first glance, it seems easy, but in actual use, first cut the adhesive tape to an appropriate length, adhere to the back of the paper sheet, peel off the adhesive tape release paper, paste it on the target mount, etc. There is a problem that many steps have to be taken, which is troublesome and very troublesome.

[0004]

In order to solve the above-mentioned problems, the present invention provides an insertion wedge for facilitating the insertion of a double-sided adhesive tape between a paper sheet and an object to be stuck, and a double-sided adhesive tape. A guide for introducing the adhesive tape, a transfer mechanism for the adhesive tape, and a pressing means for ensuring adhesion by the inserted adhesive tape are integrally provided, and among these, an insertion wedge, a transfer mechanism, and a pressing means are provided. It has a mechanism that works in conjunction with the lever, and a series of operations from the insertion of the adhesive tape to the completion of the bonding can be performed smoothly and easily. A tape dedicated to the machine of the present invention has been devised to facilitate transport inside the machine and insertion between a sheet and an object to be stuck.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the machine of the present invention, when the lever is depressed, the double-sided adhesive tape is guided along the guide by the rotation of the transport vehicle and transported in the direction of the insertion wedge. As the insertion wedge is inserted between the paper sheet and the object to be pasted, the double-sided adhesive tape is also inserted. Immediately after insertion is complete, the pressure vertebra falls directly above the insertion site to ensure adhesion.

A guide having a U-shaped groove is provided to guide the double-sided adhesive tape in a desired direction. The guide is installed from the supply source of the adhesive tape to the transfer vehicle and from the transfer vehicle toward the insertion wedge entrance. The guide is arranged so as to sandwich both edges of the adhesive tape from the left and right, and the inside of the U-shaped groove has a smooth finish so that the adhesive tape can move smoothly along the guide. The interval at which the guides are placed on both sides of the adhesive tape almost matches the width of the adhesive tape,
The adhesive tape should not be too loose or too tight so as not to over tighten.

[0007] The insertion wedge is formed by arranging a pair of projections having a wedge-like shape, whose tip is thin and sharp and gradually increases in height as it goes backward, on both sides of the width through which the adhesive tape passes. You. This role is to prevent the upper surface or the lower surface of the adhesive tape from adhering at the time of transferring the double-sided adhesive tape between the paper sheet and the object to be attached, thereby preventing the insertion from becoming difficult. That is, the sheet is lifted so that the adhesive tape can be easily inserted, and serves to secure a gap with respect to the adherend.

In order to smoothly insert the tape with the movement of the insertion wedge, a guide is also provided for the insertion wedge. The guide may be fixed directly to the insertion wedge, or may move independently of the insertion wedge.

[0009] When deciding the position where the paper sheet is to be pasted on the object to be pasted, it is applied to the desired place by hand and both are brought into close contact with each other.
Usually there are few gaps. In order to allow the insertion wedge to be inserted smoothly from one end of the paper sheet, it is desirable that this tip is made as thin as possible.

[0010] If the tip is slightly inserted into the gap,
Subsequent pushing is easy. The height behind the projection of the insertion wedge should be such that a sufficient gap can be inserted without the double-sided adhesive tape adhering. The desired height depends on the width, thickness, and insertion depth of the double-sided adhesive tape to be used, and must be carefully determined.
If it is too low, the tape will stick on top or bottom, preventing smooth insertion. If it is too high, the adhesion may be insufficient. Desirable heights are 25% to 150% of the width of the adhesive tape. Also, a minimum height of 3 mm is required regardless of the width of the adhesive tape.

The upper surface of the insertion wedge that touches the sheet has a smooth curve continuously from the front end to the rear, and the finish of the workpiece should be as smooth as possible. This is to prevent the paper sheet from being caught at the time of insertion.

The adhesive tape is transported by rotating a transport vehicle having claws on its circumference or by directly moving the feed claws. Either method is a mechanism linked with the lever. Since holes are formed in the tape at predetermined intervals as described later, the claws fit into the holes, thereby preventing the tape from slipping and ensuring the feeding of a predetermined size.

Before the double-sided pressure-sensitive adhesive tape is fed into the insertion wedge, the separator (release paper) outside the tape is peeled from the pressure-sensitive adhesive layer. Peeling is preferably performed immediately before being fed into the insertion wedge as much as possible. Thereafter, the pressure-sensitive adhesive layer becomes the outermost surface on both sides of the tape and is sent to the insertion wedge.

The insertion wedge is associated with the lever. That is, the insertion wedge is inserted between the paper sheet and the object to be pasted at the same time as the lever is pressed down. At this time, the tape is also inserted as the insertion wedge advances. Immediately after the tape insertion is completed, this also works with the lever, and the pressing vertebra, which has already been lifted from the initial operation position, falls onto the paper sheet at the inserted tape position, and strongly presses the tape. And complete adhesion between the paper sheet and the object to be stuck.

As is clear from the role, the shape of the lower part of the pressing vertebra is desirably a plane which is kept parallel to the sheet surface, and its area is desirably substantially the same as that of the inserted adhesive tape. At the place corresponding to the paper sheet, a cushioning material is stuck in order to cushion and leave no trace of impact.
Suitable materials include, for example, felt, rubber, non-woven sheets, porous plastic sheets, and the like.

In general, a commercially available double-sided adhesive tape cannot be used for the tape used in the machine of the present invention. The tape dedicated to this machine has a basic structure with an intermediate layer as a support, an adhesive layer on both sides, and a separator on the outside, but the difference from ordinary products is that the overall width of the support is The pressure-sensitive adhesive layer is not formed, and a space having no pressure-sensitive adhesive layer is left at a fixed width inward from both edges. This is important so that the tape can be smoothly moved according to the guide of this machine.

The desirable width of the space where no adhesive is applied is as follows.
A minimum value of 1 mm is required on one side of the tape. Below this, when the tape moves, it tends to adhere to the guide or to come off. It is desirable that the maximum value is up to 40% of the width of the entire support as a sum of both sides. Above this, the effective width of the pressure-sensitive adhesive application with respect to the width of the support is too small,
Adhesion is likely to be incomplete.

The properties that the material constituting the support should have are:
It is desirable to have strength against bending. If the strength is too low, when inserting the tape into the paper sheet, it will not go straight in the direction of travel and will sag, and the upper or lower surface of the tape may adhere to the paper sheet or the object to be pasted before the insertion process is completed. is there.

When the product is made into a roll, a material having such a property that the roll is likely to remain is avoided. Curling can easily cause trouble when inserting the tape. If the material is paper,
A so-called "beam" is desirable. As the plastic material, polypropylene, polystyrene, polyethylene, OPS, polyethylene terephthalate, hard polyvinyl chloride, fluororesin, or the like is used.

The thickness of the support is 0.05 mm to 2 mm
Up to is recommended. If the thickness is 0.05 mm or less, there is a possibility that sagging occurs and insertion becomes difficult. At a thickness of 2 mm or more, the tape loses its flexibility and prevents smooth movement when passing through the guide. There is no problem when finishing the product into a single elongated stick, but when winding it into a roll, there is a gap between the separator and the adhesive, and there is a possibility that so-called nests may occur. Not only is there a possibility that even if it is rewound, the winding will remain and it will not be straightened, which will hinder insertion.

For forming the adhesive layer, an adhesive may be applied directly to the support, or may be once formed into a double-sided adhesive tape and then applied to both sides of the support. Which method is to be used depends on the ease of forming the pressure-sensitive adhesive on the material of the support and the convenience of the production process.

Examples of the pressure-sensitive adhesive include vinyl, silicon, acrylic, and rubber-based adhesives which have been conventionally used. Judgment is mainly made from the coating performance of the support material to the material and the adhesive strength to the object to be bonded. Decide.

As the separator, a separator treated with a conventionally used silicone release agent is used. Holes are provided at regular intervals in the longitudinal direction to ensure transfer.
The number of holes and their positions are usually made at the center when the number of holes is one with respect to the tape width, and two or more holes are used when the tape width is relatively wide. Alternatively, cuts may be made at both edges of the tape. The shape of the hole may be any of a circle, an ellipse, and a rectangle. For convenience in production, it may be perforated not only through the separator but also through the support and the adhesive layer.

The width of the separator may be the same as that of the support, or may be the same as that of the pressure-sensitive adhesive layer.
It is selected mainly for convenience in manufacturing. In the production of a tape, in the case of a wound form, the separator may not be provided on both sides but may be provided on only one side.

When the insertion of the double-sided adhesive tape between the paper sheet and the object to be pasted is completed, the tape needs to be processed in advance in order to facilitate separation from the subsequent tape. In this practical mode, the support including the adhesive layer is continuously pierced at regular intervals over the entire width of the tape, a chain line cut (perforation) is made with a blade, or the thickness of the support is constant. Insert the blade to the depth, and connect it only with the remaining thickness (half cut),
Alternatively, there is a method in which cutting is performed by completely inserting a blade, and the separated support is merely attached to the separator. Either method may be used, but when the machine is pulled up after the insertion is completed, a judgment is made based on whether or not the tape is easily detached from the already adhered tape and whether or not it is easy to manufacture.

The width of the pressure-sensitive adhesive layer of the double-sided pressure-sensitive adhesive tape and the interval between separations per insertion are determined in consideration of the size and thickness of the paper sheet to which the machine is mainly applied, and the reliability of bonding at the time of completion of bonding. Judge from and decide. The degree of bonding increases as the bonding area increases. However, when the tape width is determined, the tape feed must be lengthened to increase the bonding area. This implementation requires the insertion wedge to be inserted deep from the end of the paper sheet. The longer the insertion depth, the more likely it is that a problem will occur in tape feeding, and the greater the mechanical difficulty. From these, a desirable interval is 0.5 to 5 times the entire width of the tape. More preferably, it is 1 to 2 times. If it is 0.5 times or less, the bonding area is reduced, the bonding strength is reduced, and peeling is easy.

[0027]

An embodiment will be described with reference to the drawings. FIG. 1 shows the main components of the main body of the present invention. Two side plates 1
The movable components and the fixed components of the main components are supported by (a front side is omitted for easy viewing). The lever 2 is pivotally supported by the side plate 1 and returns from the depressed position to the original position by a spring (not shown). The figure shows the state before pushing down.

Reference numeral 10 denotes a transfer vehicle having one or a plurality of projections 14 at the center or both ends of the peripheral surface. Since holes 56 are formed at regular intervals in the separator 54 of the double-sided adhesive tape 50, the tape is transported as the transport vehicle 10 rotates with the projections 14 caught thereon. The shaft 13 is pivotally supported by the side plate 1 and is coaxially fixed to the ratchet wheel 12.
With. When the lever 2 is pressed down, the operating claw 20 pivotally supported by the lever is engaged with the claw 15 of the ratchet wheel 12,
The movement of the lever is transmitted to rotate the ratchet wheel 12, and the transfer wheel 10 fixed coaxially also rotates. The number of claws of the ratchet and the number of protrusions on the transfer wheel are usually made to match. In this case, the distance by which the tape is transported for each operation of lowering the lever to the lower limit naturally corresponds to the circumferential length (pitch) between the projections of the transport vehicle.

Reference numeral 30 denotes an insertion wedge. It is supported by rails 31 provided on both side plates 1 and can freely move back and forth. The lever 2 is linked to the lever 2 by a connecting lever 32. When the lever is pressed down, the insertion wedge 30 moves forward. At this time, since the transfer vehicle 10 is also rotating at the same time, the tape moves forward in accordance with the moving speed of the insertion wedge, and is inserted between the paper sheet and the object to be pasted.

In FIG. 1, a pressing vertebra 40 is used as the pressing means. It is supported by both side plates 1 (the support mechanism is omitted in the figure) and freely moves up and down. 41 is a cushioning material. Lever 2
Is hooked on the hook 44 of the pressing vertebra 40, and is raised as the lever is pushed down. When a certain height is reached, the lifting claw 43 comes off the hook 44, and the contracted pressing spring 42 is released and extended, so that the pressing vertebra is vigorously knocked down. Since the drop position is directly above the adhesive tape already inserted through the paper sheet, the adhesive tape can completely adhere the paper sheet to the object to be stuck. In the front part of the machine, just below the pressing vertebra, a gap for the paper sheet to enter is provided a few mm from the bottom surface.

After the pressed vertebra falls, a return spring 45 is provided to return to the position before the start of operation. Since this role merely raises the pressure vertebra slightly from the sheet surface to create a gap, the elasticity of this spring may be much smaller than that of the pressure spring 42.

In the embodiment shown in FIG. 4, a pressing piece 46 is attached as a pressing means by a hinge. Press down from above as soon as the insertion of the adhesive tape is completed.

In the embodiment shown in FIG. 5, a pressing roller 47 is attached. Move back and forth to complete the bond.

The use procedure and the order of operation of the machine of the present invention will be described. The tip of the insertion wedge 30 is inserted into the gap between the paper sheet and the object to be pasted. In this position, the machine is further advanced until a part of the paper sheet is directly below the pressing vertebra 40. Next, while holding the state, when the hand is pressed down the lever 2, the operating claw 20 is engaged to rotate the ratchet wheel 12, and rotate the coaxial transfer vehicle 10 by one pitch of the pawl 15. . Since the protrusion 14 is fitted in the hole 56 formed in the separator 54 of the double-sided adhesive tape 50 shown in FIG. 6, the tape moves along the guide 35. By a turning pin 48 provided immediately before the transfer vehicle 10,
The separator, which has been moving integrally with the tape body, can be turned at an acute angle, so that the separator moves away from the tape body. The tape body is an insertion wedge 30
It is introduced into the introduction guide 33 (FIG. 2). The insertion wedge is moved forward as the lever is pushed down by the connecting lever 32 engaged with the lever 2. At this time, the tape body also moves forward and is inserted between the paper sheet and the object.

At almost the same time when the insertion is completed, the pressing vertebra 40 falls to complete the adhesion of the tape. Immediately after pressing vertebra 4
0 is slightly lifted upward by the return spring 45.
The lever 2 returns to its original position by a spring (not shown). In connection with the return operation, the insertion wedge 30 also returns to the original position, and a series of operations is completed. As shown in FIG. 6, the double-sided adhesive tape has cuts 55 at predetermined intervals so as to be easily separated at predetermined lengths, so that the double-sided adhesive tape can be easily separated from the inserted adhesive portion. .

It is conceivable that the path from the winding body 59 of the double-sided adhesive tape to the insertion wedge 30 is different from that in FIG.
In the case of FIG. 1, the tape is supplied from above the transfer vehicle (that is, the side closer to the lever 2), and the separator 54 separated by the deflecting pin 48 is discharged backward from below. In another path, the tape is supplied from below, and the separator separated by the deflecting pin is discharged upward through a transfer vehicle. On the other hand, the tape body faces the insertion wedge. The direction of rotation of the transfer vehicle is opposite to that of FIG. The advantage of adopting this supply path is that the moving direction of the tape main body is almost straight from the bottom toward the insertion wedge, so that the movement direction of the insertion wedge coincides with that of the insertion wedge, and deformation such as bending of the tape during the movement can be avoided. it can. Therefore, it is easy to achieve smoother tape insertion.

The double-sided pressure-sensitive adhesive tape will be described with reference to the drawings. FIG. 6 is seen from the top surface of the tape. Support 5
The pressure-sensitive adhesive layer 52 is formed leaving a pressure-sensitive adhesive non-applied portion 53 having a certain width from both edges of the first adhesive layer 1, and a separator 54 is attached thereon. Holes 56 are formed in the separator at regular intervals. This distance is matched to the distance between the projections of the transport vehicle. The holes may be formed through the support 51 and the pressure-sensitive adhesive layer 52 for manufacturing convenience. The width of the separator 54 may be the same as that of the pressure-sensitive adhesive layer, or may be the same as the width of the support. In order to facilitate the separation of the tape, in FIG.
Has been put.

FIG. 7 is a sectional view. An adhesive layer 52 is formed on both sides of the support 51. When the tape is finished as a wound body, the separator 54 may have only one layer on one side, but when the product is in the form of a stick having a certain length, the separator 54 has both sides.

FIG. 8 shows a double-sided pressure-sensitive adhesive tape obtained by re-applying a tape having an adhesive applied on both sides of the support 51a and pasting the tape on both sides of the support 51.

FIG. 9 shows a state in which independent adhesive members 52b are attached to both sides of the support between the cuts. The separator is omitted. This method is suitable for an adhesive having a relatively thick body. The preferred thickness of the adhesive is about 0.5 mm to 3 mm.

[0041]

The present invention is embodied in the form described above, and has the following effects.

Since the transfer of the double-sided pressure-sensitive adhesive tape, the insertion wedge, and the operation of the pressing means are all interlocked with the lever, a series of operations from the insertion of the pressure-sensitive adhesive tape to the completion of the bonding can be smoothly and easily achieved.

By the function of the insertion wedge, the double-sided adhesive tape can be smoothly inserted between the paper sheet and the object to be stuck.

By the function of the pressing means after the double-sided pressure-sensitive adhesive tape is inserted, the adhesion is reliably achieved.

The double-sided pressure-sensitive adhesive tape dedicated to the present invention is provided with a non-coated portion of the pressure-sensitive adhesive on both edges of the tape support.
Smooth movement is possible along the guide installed in the machine, and insertion between the paper sheet and the object to be pasted by the insertion wedge is easily achieved.

By cutting the double-sided pressure-sensitive adhesive tape every fixed section, the cutting can be easily achieved without cutting with scissors or the like.
