Description

The present invention is a sheet capable of binding a plurality of sheet materials (including paper, synthetic resin film, metal film, medicine bag, food packaging material, etc.) without using a metal binding needle or glue. Regarding the material binding machine.

Conventionally, many booklets, forms, etc. are created by binding with metal binding needles, glue, or the like. In addition, in medicine bags and food packaging materials, a plurality of bags are bound into one and stored or displayed at the same time. However, metal binding needles are dangerous if the binding needles stick out. In addition, when booklets and forms are no longer needed and are discarded, they are cut with a shredder as necessary and reused as recycled paper from the viewpoint of incineration or resource saving, and metal binding needles. In order to avoid damage to the shredder blade, it is necessary to remove the metal binding needle, and it is difficult to dispose of it. On the other hand, those bound with glue or the like have a problem that toxic gas is generated at the time of incineration when the glue is a resin-based glue such as hot melt.

In order to deal with these problems, paper can be bound without using metal needles or glue. For example, when binding multiple sheets of sheet material (copy paper, forms, etc.), one Described are devices that supply moisture to each sheet of paper and apply pressure from above and below to bind the sheets with a binding member having a series of irregularities (for example, Patent Documents 1 and 2).

However, since these contain water and the like, they cannot be easily bound and the structure is large. Therefore, as shown in FIG. 8, the applicant of the present application, as the inventor of these, binds the handy type. The machine was developed (Patent Document 3). According to the binding machine of Patent Document 3, in addition to being a handy type, one side skeleton ( fixed block ) in which one uneven tooth is arranged and the other side skeleton (fixed block) in which the other uneven tooth is arranged (fixed block). ), Since a gap (a gap through which the sheet material passes) is provided, there is an advantage that the structure can be made simple.

By the way, there is a request that a conventional binding machine (including Patent Documents 1 to 3) wants to bind as many sheets as possible. The demand for the above-mentioned conventional binding machine is also high. At present, the maximum number of sheets is 3 to 5 for plain paper and 4 to 6 for thin synthetic film. Further improvement is needed. In addition, there are various types of sheet materials such as paper sheets, synthetic resin sheets, and cellophane, and it is necessary to bind medicine bags and food bags, and there is a high demand for binding as neatly as possible. Therefore, it is necessary to apply pressure to the binding margin as appropriate according to the type.
On the other hand, depending on the size and type of one uneven tooth and the other uneven tooth (steel tooth sharpness, etc.), the number of overlapping teeth may differ, or the meshing of these teeth may not be appropriate. It also had problems such as damaging the sheet material. That is, it is difficult to properly set the gap between one uneven tooth and the other uneven tooth (it is also difficult to set for the transport stage), and as the number of sheet materials increases, the uneven teeth of each other Causes a situation (paper jam) in which the sheet material is bitten. And once the tooth spacing is out of order, it is difficult to return to the original proper spacing.
Further, even binding a plurality of sheets by a pair of concave-convex teeth may occur a plurality of sheets Gameku Re up phenomenon resulting reaction, it is necessary countermeasures. Then, it is necessary to suppress these phenomena and bind a plurality of sheet materials.

When the slip occurs, there is a problem that the sheet material becomes shiny and uneven tooth marks are formed so as to draw a line, which impairs the aesthetic appearance of the sheet material. Therefore, such a phenomenon must be solved.
Further, in Patent Documents 1 and 2, the apparatus configuration is complicated and expensive, but there is a problem that it is particularly difficult to set the interval at which the sheet material passes. That is, in the above-mentioned conventional example, a gap for supplying the sheet material is separately provided (such as by arranging it on the outside of the skeleton), or a guide portion for guiding the gap is required, and the gap is required depending on the type of uneven teeth and the like. The problem was that the degree of protrusion (adjustment of the gap between the gaps) was difficult.

Therefore, an object of the present invention is to make the distance between one uneven tooth and the other uneven tooth appropriately adjustable so that the binding pressure can be adjusted according to a plurality of sheet materials, and the meshing of the uneven teeth is inconvenient.

The pressure applied to the uneven teeth and the sheet material can be adjusted by combining with the first elastic member) or with the second adjusting means (second elastic member). That is, the elastic force of the second adjusting means (second elastic member) can be adjusted while the binding pressure between the one concave-convex tooth and the other concave-convex tooth is kept constant, or the one side. The elastic force of the first adjusting means (first elastic member) can be adjusted while keeping the distance between the skeleton and the other side skeleton constant.
Further, it is provided with a one- sided skeleton to which one of the concavo-convex teeth is attached and a other-side skeleton to which the other concavo-convex tooth is attached, and any of these skeletons is configured to be movable along a slide strut. It is characterized in that the one-sided skeleton is brought into contact with and separated from the other-sided skeleton by the operating means via a pushing-down member arranged between them.
According to the present invention, it is possible to release the pressing force by the operating means while the pressing force by the operating means is applied to the one-sided skeleton (while the binding pressure on the sheet material is kept constant). Therefore, even if a paper jam occurs, the paper jam can be cleared and the original pressing force can be returned without changing the pressing force by the operating means. In addition, the positions of the uneven teeth with respect to the transport table can be precisely set.
The present invention has a structure in which the elastic member for adjusting the distance between the uneven teeth and the elastic member for adjusting the distance between the skeletons are arranged to face each other and operate in cooperation with each other, and the elastic member for adjusting the distance between the skeletons is used during normal operation. The elastic member for adjusting the uneven tooth spacing has a stronger elastic force, but when the elastic force for adjusting the concave-convex tooth spacing is released, the elastic force for adjusting the inter-body spacing causes the elastic force. It is characterized in that the distance between one side skeleton and the other side skeleton is widened.
Here, the elastic force is a pressing force (urging force), a stretching force or a pressing force from above when the skeletons on one side and the other side have a vertically arranged structure, but is not limited to the vertically arranged structure. It is possible.
According to the present invention, the elastic member for adjusting the uneven tooth spacing and the elastic member for adjusting the inter-body spacing are arranged in opposite arrangement and cooperate with each other (not limited to the vertical arrangement). You can adjust the urging force of. If the distance between the one-sided skeleton and the other side skeleton is set in advance by the elastic member for adjusting the uneven tooth spacing, then the one-sided skeleton can be slightly adjusted by the strength of the elastic force of the elastic member for adjusting the distance between the skeletons. It becomes possible to adjust the distance between the and the other side skeleton.
Further, according to the present invention, a transport table for transporting the sheet material, a guide portion arranged along the transport table to guide the sheet material, and a plurality of sheets to be supplied and discharged along the guide portion.

In the present invention, the one-sided skeleton and the other-side skeleton are arranged separately in the upper and lower portions, so that at least one of the one-sided concave-convex tooth and the other concave-convex tooth is formed in the separated gap. By projecting and / or arranging them separately to the left and right, at least one of the one concave tooth and the other concave tooth is projected and arranged in the separated gap. It is characterized by that. Here, the concavo-convex tooth is not limited to the rotating tooth, and may be a linear concavo-convex tooth, that is, one that is linearly arranged to face each other and pressed as an upper and lower mold by a press or the like.
In conventional binding Ji write device, it could only provide a gap between one side skeleton and the other side skeleton of the upper and lower arrangement. On the other hand, according to the present invention, since the elastic member for adjusting the uneven tooth spacing is arranged between the pushing-down member and the one-side skeleton, the operating means is used against the elastic member for adjusting the concave-convex tooth spacing. It can be pushed down through the pushing down member, and can be pushed down according to the number of sheet materials (binding pressure can be obtained). Therefore, the sheet material can be sandwiched by the uneven teeth protruding in the gap between the one side skeleton and the other side skeleton, not limited to the vertical arrangement. Further, if the one-side skeleton and the other-side skeleton are divided into two parts, left and right, in addition to the upper and lower skeletons, the urging force (elastic force) of the elastic member for adjusting the uneven tooth spacing can be applied at any position of the upper and lower gaps and the left and right gaps. It is possible to set the gap to be exhibited, and it is possible to insert and bind the sheet material not only from the horizontal direction but also from the vertical direction.

According to the present invention, when a plurality of sheet materials are overlapped and sandwiched between one side skeleton in which one uneven tooth is arranged and the other side skeleton in which the other uneven tooth is arranged, the uneven tooth spacing is adjusted. Since the uneven marks are given to the plurality of sheet materials via the elastic member for the purpose, it is possible to make uneven marks (good uneven marks depending on the material of the sheet material) that are difficult to peel off. In addition, the number of sheets to be stacked is increased as compared with the conventional case, slip is prevented, and transportation (supply and delivery) is improved.
Further, it is possible to adjust the appropriate interval according to that bind number and type regulation of the gap between one side skeleton and the other side skeleton by an elastic member for between uneven teeth interval adjustment. Then, damage to the uneven teeth can be prevented to prolong the life of the uneven teeth, and when the sheet material is bitten , the pressing force of the pressing member is relaxed to provide an elastic member for adjusting between the skeletons. The distance between the concavo-convex teeth facing each other is automatically widened, and the sheet material can be removed. The degree of protrusion of the uneven teeth (setting of the rotating teeth to protrude into the gap between the one-sided skeleton and the other-side skeleton) becomes easy.
Further, it is provided with a one- sided skeleton to which one of the concavo-convex teeth is attached and a other-side skeleton to which the other concavo-convex tooth is attached, and all of these skeletons are configured to be movable along the slide support. It becomes possible to accurately align the position of the uneven tooth with respect to the table and the notched flat surface portion of the uneven tooth.

Are rotatably incorporated into the skeletons 10 and 11, respectively (FIGS. 1 to 4).
The skeleton (fixed block) 5 is composed of an upper skeleton 10 and a lower skeleton 11, and the upper skeleton 10 and the lower skeleton 11 are further divided into left and right, and the upper left skeleton 10a and the upper right skeleton 10b. It is composed of a lower left skeleton 11a and a lower right skeleton 11b, and the upper skeleton 10 and the lower skeleton 11 are detachably fixed by bolts (slide struts) 22, and the upper left skeleton 10a and the upper right side. The skeleton 10b, and the lower left skeleton 11a and the lower right skeleton 11b are detachably connected by compression springs 51, 52, and 53, respectively.
Further, a transparent transfer table 61 is arranged so as to be located between the upper skeleton 10 and the lower skeleton 11, and the sheet material 4 is conveyed along the guide portion 60 at the end of the transfer table 61. Will be done. That is, a guide portion (U-shaped member) 60 is arranged at a position at the back where the uneven teeth 1A and 1B at the back of the transport table 61 mesh with each other, and a U-shaped space portion (upper plate 60a and side plate 60b) is arranged. The end portion of the sheet material 4 is positioned and conveyed in the L-shaped space formed by the above. The guide portion 60 is screwed to the transport table 61, and the tip end side 60a thereof can be configured to be vertically movable (FIGS. 12 and 16). The guide portion 60 is also arranged at the position of one of the uneven teeth 1A, and flattens the plurality of sheet materials 4 from above via the upper holding plate 71b.
In FIGS. 1 to 3, reference numeral 1E is a control unit for driving and controlling the uneven teeth 1A and 1B, reference numeral 63 is a pressing type controller, and reference numeral 62 is transparent plastic. Reference numeral 59 is a rotation axis of the gap adjusting member 60, which is connected to the driving means M (FIG. 3). Further, in FIGS. 5 and 6, a slide column 80 is arranged, and a pressing member 58 is attached to the slide column 80 so that the upper skeleton 10 can be brought into contact with and separated from the lower skeleton 11. It has become. That is, when the operating means 50, which is the operating means, is rotated, the pressing member is lowered via the operating means 55, and the upper skeleton 10 is brought into contact with and separated from the lower skeleton 11.

The left upper skeleton 10a and the upper right skeleton 10b are provided with insertion holes 12a and 12b through which the upper rotation shaft 6 is rotatably inserted, and the upper rotation is performed between the upper left skeleton 10a and the upper right skeleton 10b. A space portion 13 is formed which accommodates the upper gear 2 fixed in the middle of the shaft 6 and projects the uneven teeth 1A of the upper gear 2 from the lower surface of the upper skeleton 10.
Further, the lower left skeleton 11a and the lower right skeleton 11b are provided with insertion holes 14a and 14b through which the lower rotation shaft 7 is rotatably inserted, and are provided between the lower left skeleton 11a and the lower right skeleton 11b. Accommodates the lower gear 3 fixed in the middle of the lower rotating shaft 7, and projects the concave-convex teeth 1B of the lower gear 3 from the upper surface of the lower skeleton 11 of the lower gear 3. A gap S is formed in which the uneven teeth 1B mesh with the uneven teeth 1A of the upper gear 2 protruding from the lower surface of the upper skeleton 10.

Then, in the incorporation of the upper rotating shaft 6 in which the upper gear 2 is fixed to the upper skeleton 10, one end side of the upper rotating shaft 6 is inserted into the insertion hole 12a of the upper left skeleton 10a from the forming surface side of the space portion 13. Insertion, the end portion is projected from the upper left side skeleton 10a, and the other end side of the upper rotation shaft 6 is inserted into the insertion hole 12b of the upper right side skeleton 10b from the forming surface side of the space portion 13, and the end portion is inserted. It is projected from the upper right skeleton 10b, and the upper left skeleton 10a and the upper right skeleton 10b are fixed with bolts (slide columns) 22 (FIG. 3).

In this way, between the upper skeleton 10 incorporating the upper rotating shaft 6 to which the upper gear 2 is fixed and the lower skeleton 11 incorporating the lower rotating shaft 7 to which the lower gear 3 is fixed, A gap S is formed between the upper gear 2 and the lower gear 3 to feed the plurality of stacked sheet materials 4.
Further, in this embodiment, the lower concavo-convex tooth 1B of the opposing concavo-convex teeth 1A and 1B is used as the drive shaft 59 and is connected to the drive source. The drive shaft 59 is connected to the drive means M via a coupling 59a (FIG. 5). The uneven tooth 1A on the upper side has a structure that is rotated by a driven shaft. It is also possible to reverse the relationship between the drive shaft 59 of the concave-convex tooth and the driven shaft, or to arrange the drive means M in any of them.

In the present invention, a plurality of sheet materials 4 are superposed and fed and sandwiched between one concave-convex tooth 1A and the other concave-convex tooth 1B. An elastic member 51 for adjusting the spacing between the uneven teeth is arranged so as to elastically sandwich the plurality of sheet materials 4 by the gap S. The elastic member 51 for adjusting the uneven tooth spacing is arranged and connected to the storage hole 51a formed between the one-side skeleton 10 and the other-side skeleton 11. It is also possible to attach the slide support so as to wind it along the slide support 22. Further, by arranging a rubber material or the like in the storage hole 51a, it is possible to further exert elasticity.

Further, an operating means 50 is provided as an operating means for adjusting the distance S between the one-sided skeleton 10 and the other-side skeleton 11. The operating means 50 is provided with a pushing-down member 58, and has a structure in which the upper skeleton (fixed block) 10 and the skeleton 11 operate in cooperation with each other via the pushing-down member 58 and the elastic member 52 for adjusting the distance between the skeletons. That is, a fixing member 57 is built in the upper skeleton 10, and an elastic member 52 for adjusting between the skeletons is attached to the fixing member 57 so as to exert an elastic force. Then, when the upper operating means 50 is rotated, the pushing-down member 58 is pushed down, and the distance between one concave-convex tooth 1A and the other concave-convex tooth 1B can be adjusted. The gap S can also be adjusted with the elasticity of the elastic member 52 for adjustment.

The elastic member 51 for adjusting the distance between the uneven teeth and the elastic member 52 for adjusting the distance between the skeletons are arranged vertically and cooperate with each other, and the uneven teeth are more than the elastic member 52 for adjusting the distance between the skeletons. The elastic member 51 for adjusting the interval is arranged upward so that the urging force (pressing pressure from above) and the elastic force are stronger. That is, a spring is used for the member 51 for adjusting the spacing between the uneven teeth and the elastic member 52 for adjusting the spacing between the skeletons, but the elastic member 52 for adjusting the spacing between the skeletons is more than the elastic member 51 for adjusting the spacing between the skeletons. The one that is long and has weak urging force and elastic force is used. The third elastic member 53, which will be described later, is shorter than the elastic member 51 for adjusting the uneven tooth spacing and has a stronger urging force (elastic force), like the elastic member 52 for adjusting the space between the frames. ..

Therefore, when the sheet material 4 is supplied to the gaps S of the skeletons 10 and 11 by using the binding machine 1 of the first embodiment, the sheet material 4 is sandwiched between one uneven tooth and the other uneven tooth, and uneven marks are formed. Granted. In the gaps S between the skeletons 10 and 11, the elastic force of the spring, which is the elastic member 51 for adjusting the uneven tooth spacing, acts to prevent the plurality of sheet materials 4 from being peeled off and can be bound. In addition, when separating each sheet, it is possible to easily remove each sheet because there are only uneven marks and no needles or adhesives are used.
Further, since the elastic member 51 for adjusting the uneven tooth spacing and the elastic member 52 for adjusting the distance between the skeletons are arranged vertically and cooperate with each other, the urging force (pushing pressure) of each other can be adjusted. .. For example, the elastic member 52 for adjusting the inter-body spacing is arranged higher than the elastic member 51 for adjusting the uneven tooth spacing to increase the urging force, so that the elastic member 51 for adjusting the uneven tooth spacing can be formed. The distance S between the arranged one-sided skeleton 10 and the other-sided skeleton 11 can be adjusted so as not to open too much unnecessarily.
When the sheet material 4 is a synthetic resin film, a metal film, or the like, the gap S is adjusted by the operating means 50 accordingly, but the adjustment by the operating means 50 and the skeleton 10 and the skeleton 11 are adjusted. Since the gap S is adjusted by the elastic member 51 for adjusting the spacing between the uneven teeth and can be operated in a coordinated manner, it can be adjusted according to the type, hardness, and softness of the sheet material 4, and one concave-convex tooth 1A and the other. The distance from the uneven tooth 1B can be adjusted. Further, by loosening the operating means 50, the distance between the skeleton 10 and the skeleton 11 is widened, and the skeleton 10 is automatically pushed up by the elastic member 52 for adjusting the distance between the skeletons, and the distance between the uneven teeth 1A and the uneven teeth 2A is increased. Therefore, the sheet material 4 can be easily removed when the sheet material 4 is caught. The sheet material 4 includes a synthetic resin film, cardboard, thin paper, corrugated cardboard, a medicine bag containing medicine, a tea bag, or the like, which is a sheet-like bag (food bag) having a predetermined thickness in the center and a sheet around the circumference. It can also be used when binding the sheet-shaped end of a cardboard box, etc.).

6 (a), (b), and (c) show a state in which the single-dose medicated bags 4 are overlapped in the vertical direction and bound. By stacking a plurality of synthetic resin film medicated bags 4 and binding them with the uneven teeth 1A and 1B at the same time, uneven marks are imparted and the plurality of sheets can be bound.
Further, in the second to fourth examples of FIGS. 7 to 10, in addition to the ones in which the rotating teeth are used with each other, the ones in which the rotating teeth and the linear uneven teeth 1A and 1B are arranged to face each other (FIG. 9). , This is an example in which linear concavo-convex teeth are arranged so as to face each other (FIG. 10). In each case, an elastic member 51 or the like for adjusting between the skeletons is arranged between one side skeleton and the other side skeleton. In any combination of the above, the spacing between the gaps S can be appropriately bound corresponding to a plurality of sheet materials 4. Further, since one uneven tooth 1A and the other uneven tooth 1B are arranged at positions along the tip of the one side skeleton 10 and the other side skeleton 11 on the side extending to the gap S, the alignment is easy. is there.
Further, the upper and lower uneven teeth 1A and 1B are provided with flat portions 6c having no uneven teeth (FIG. 7). Due to the presence of the flat portion 6c, when it is desired to stop the addition of uneven marks, the sheet material 4 can be taken out in the middle of the process.
