Description

200424096 Description of the invention [Technical field to which the invention belongs] The present invention relates to a special scribing knife for assembling storage containers and for cutting the bending line, such as articles, stationery, toys, food, etc. Thinning equipment for containers. [Prior art] Traditionally manufactured thin plates with bending scribe lines, for example, a plastic scribe edge forming a concave or convex scribe line on the top surface of a thin blade, make a bending scribe line with deep grooves and% grooves, as a true bend The top surface of the plastic thin-bladed blade with curved lines announced by Fair 4-9345 forms a side-lined blade with a slightly semi-straight convex blade, pressed against a thin semi-circular shallow groove and a slightly straight Deep groove #knife is a plastic sheet invented by Japanese Patent Laid-Open No. 2001-29377. A scribing knife with fine unevenness was formed with the blade edge. Drawing J shows that the entire inner surface of the f-folded scribing line is formed into a thin line. Japanese Unexamined Patent Publication No. 6-23835. 'Using the above-mentioned Japanese too. Iw the true and fair "9345 公 专 板 #Japanese Invention Special Publication 2001-293777 sheet material, the book | 丨 ^, the bendability of the sheet line made of wire knife is different. f "How to improve the raw parts, but if you use a thinner plate to store makeup materials and add a sharp edge and a slight side, it is considered to form a bent bend line and a bend part method, such as but the plastic line of the line Although the board is useful for pressing on the sheet part with a knife. For example, a 0-shaped concave knife is used to draw a line from the bend. The thickness-changed part of the bent bottom is continuously continuous in the direction of length 3 200424096. When the sheet is along the bottom, it is easy to crack or press on the sheet, which penetrates the commercial value of bent foreign matter such as garbage or moisture from the opening. It is an acute angle with the degree of sanitation, bending, etc. Moreover, its scribing knife eats as a thin plate when it is pressed and unfolded in the plane direction. The small thin plate with low elongation will appear small, biodegradable plastic plates are skewed, reverse warped or Corrugated, outer plastic It is difficult to mechanize the assembly of plates and containers into containers. If you bend the line to bend, you bend the hole. In addition, if you scribe the thinner part of the bottom of the line with a scribe, it will enter everywhere and affect the storage container. In addition, because The feel of the step in the groove part is not good, and when it is easy to hang to a deep cloth, the thickness of the groove part will increase, and the molecular density becomes higher. When the f-folded line of the thin plate is cracked, it cannot be formed. Good. When using the shape of the mechanical group, there will be stagnation or resistance. In addition, "the Japanese invention is used to form a full shape inside the bending line: when the micro-protrusion of Hiroyuki 6_23835 is divided into small bumps," the resistance to the knife is increased, It is time-consuming and labor-intensive to process. "Folding and scribing requires a lot of effort. At the same time, the resistance to the blade's edge 'causes the angle of the scribing blade to be easily changed, so it is difficult to be soft. Degree, it can not obtain a good folding line, there will be a large storage, bending or thin skin, because of the stretch and elongation will be plugged out of the box machine, so that the method, the blade pressure is difficult to average Bendability and the problem of the invention [Problem] To propose a dedicated scribing knife with a curve, which scribes a thin plate along the fold. The object of the present invention is to aim at the above-mentioned thin plate and cut the fold line with *. 4 200424096 Attached Bending warehouse, small convex parts of μ μ, on the groove part, a number of better characteristics than the groove view are formed in the longitudinal direction to obtain good f-foldability and softness, with feel and external payment, can be carried out Mechanical bending operation. According to the present invention, the method of immersing and supporting is: a thin plate is provided with a task that is inclined at a specific angle and faces each other, a pair of side parts, and a narrow part connected to one end of the side part. Bottom surface * and + 、, concave concave bending line; a plurality of shallow grooves shallower than the bending line and deep grooves deeper than the bending line are formed along the longitudinal direction of the bottom surface P of the bending line However, a few protrusions smaller than the grooves are formed on the grooves in the longitudinal direction. In the thin plate with a curved line, each groove portion and the convex portion are formed in a smooth shape from the longitudinal direction. The above-mentioned dedicated scribe knife for the thin plate is characterized in that a concave side is provided corresponding to the bending position of the thin plate, which is used when bending the scribe, has a pair of side portions inclined at a specific angle and facing each other, and A narrow top surface portion connected at one end of the side portion; along the top surface portion of the scribing blade, several blade edges shallower than the f-fold line and blade edges deeper than the shallow blade edge are formed in the longitudinal direction; along the underside of the blade edge A plurality of concave portions smaller than the blade edge are formed in the longitudinal direction. Each of the scribe blades and concave portions for this thin plate has a smooth curved surface shape in the longitudinal direction. The above sheet can be made of plastic sheet, plastic paper synthetic material, synthetic fiber and other materials, such as polypropylene (PP), polyethylene terephthalate (PET), or biodegradable plastic. Materials or composites made of plastic, and specifications such as 200424096 degrees are transparent or translucent thin plates in the range of 0.1-1 mm (eg, about 0.3 mm). The convex portion of the fold line may be composed of, for example, a convex groove portion 5, a concave portion, a protrusion, and the like. The concave portion of the scribing blade may be formed of, for example, a concave blade edge 9, a concave portion, a pothole, or the like. That is to say, when processing the bending scribe line 2 on the thin plate 1, use one or more scoring blades 6 to apply an appropriate amount to each bending part on the thin plate 1 according to the material, thickness, strength, hardness, etc. of the thin plate 1. You can also heat the scribing knife to a certain temperature for processing, and it can be arranged in the longitudinal direction on the curved scribing grooves attached to the thin plate to form several convex portions smaller than the grooves. The groove portions 3 and 4 constituting the above-mentioned bending scribe line 2 and the respective portions B, C, D, E, F, G, 01, 0, 2 and X of the blade edges 7 and 8 constituting the sheet-specific scribe blade 6 can be determined according to The thickness A of the thin plate 1 is set to the following values. For example, the lengths B and C of the grooves 3 and 4 and the blades 7 and 8 are set to a length included in a range of about 30% to 400% of the thickness A of the thin plate 1 (for example, about 08 mrn). The height D of the blade edge 8 is set to a depth and height included in a range of about 10% to 50% of the thickness A of the thin plate 1 (for example, 0.15πηπ). The distance E between the groove 5 and the blade edge 9 is set according to the thickness A of the thin plate 1 It is a pitch included in a range of about 0.05-0.5 mm (such as 0.2 mm). The depth F of the groove 5 and the height F of the blade edge 9 are set to be shallower than the groove portion 4 and lower than the blade edge 8 and set to a thin plate. The depth and height included in the range of about 5% to 30% of the thickness A of i (for example, 0.08 mm), set the width G of the groove 4 and the blade edge 8 to about 0% of the thickness A of the thin plate 1. For a width included in a range of -1 0 0% (for example, 0.5 mm), the width Η of the groove portion 3 and the blade edge 7 is set to about 5 ° / of the thickness a of the thin plate 1. -2 00% 200424096 The template 1 contains the range lb, line 2 A is set at the thickness of the bend). The setting will change the underline as appropriate. It will change the underline as appropriate. Fold the width (for example, 0.15mm). The angle 0 of the bending scribe line 2 and the angle $ 2 of the scribe blade 6 and the thickness A are set to an angle of about 1% and 130 degrees. The thickness X of the groove portion 4 is formed to about 〇Arn- Included thickness. For example, the angle θ 1 formed at the bending portions such as the front portion ia, the rear portion lc, and the joining portion ld of the thin plate and the angle 0 2 of the scriber 6 are used to define the allowable bending angle in the f-folding direction according to the thin plate ( For example, the angle θ 1 of the fold 2 of the folded portion 1 e, the upper surface 丨 f, and the f fold of the lower portion 1 g, and the angle θ 2 of the scribe blade 6, and the root degree A sets the allowable bending angle for the inside and outside. (Tweak ► If you increase the above 3, 〇, 〇, £,?, 〇, 01, 0 < values, the feel and bend i of the bending line 2 attached to the sheet 1 are poor. If you reduce the set value, the blade strength If it is lowered, it is not enough to obtain 2. Therefore, in order to comply with the above, if the set value of the pitch interval E is increased, the bending i of the sheet is poor. If the set value is decreased, the blade strength is reduced, and it is not enough to obtain 2 Effect. Therefore, in order to comply with the above, if the setting value line 2 of the blade angle 02 of the scoring blade 6 is increased, a large pressing force is required, and processing is difficult. Sheets, corrugations, etc., the bending performance of the sheet 1 is deteriorated, and mechanization is caused. , According to the bending of the side part 1 0 // m in the thin range 1 thickness 43 degrees). According to the formed sheet 1, the bending performance is attached to the bending setting range such as about 75 2 and X. The bending performance is attached to the bending setting range, and the attached bending 1 produces a reverse bending operation. 200424096 It becomes difficult. If the setting value is reduced, the blade strength will be reduced. * ^ F It is better to observe the above setting range. As long as the value within the above range is set, the thickness, material, and strength of the sheet 1 can be used. And hardness, adjust the width, length, depth, age, pitch, and angle of the grooves 3, 4, 5 of f-fold line 2 and the blades 7, 8, and 9 of the scribe line, and set them as required. Arrangement and group :: The grooves 3, 4, 5 of the wild scribe line 2 and the blades 7, 8 ′ of the scribe line 6 can be set to be viewed from the side, front, horizontal or bottom, 9, ^% meters are smooth Any particular shape such as curved surface, semi-circle, arc-like, fan-like, ellipse-like or trapezoid-like, quadrilateral, quasi-triangular, polygon-like, etc. = grooves of f-fold line 2 formed by multiple different shapes ^ And the record r0h of the scribe knife 6 can be set to be slightly the same width or Different widths and staggered shapes ... pear-shaped patterns, small bumps, rope-like, lock-like, and other special shapes. "In practical applications, the above-mentioned small convex portions can be built on Gengqiu_Yu 丄 or Genggou 邛The above shallow grooves or deep grooves can be different in depth or depth ... The above grooves and protrusions can be based on: the thickness of the two plates to determine the predetermined size ... the grooves and protrusions can be made From the longitudinal direction, it looks like a smooth curved surface. The small recesses can be formed at the shallow or deep blades. Production ...: The sharp or deep blades can be of different depths, or they can be approximately the same depth. The blade edge and the recessed portion can be formed according to the thickness of the thin plate: square-a predetermined size ', and the blade portion and the recessed portion can be formed into a shape of a smooth curved surface from the direction of ··'. 8 200424096 The stress applied to the surface of the sheet is arranged above the grooves in the longitudinal direction, and the printing of the part is smoother, and it is better to touch the sheet with your hand. And it wo n’t hang in the design. When the portion is pressed, the scribe line can be greatly reduced during the bending and scoring process of the thin plate, and even if the stretch ratio of the present invention has a plurality of convex portions smaller than the groove portion in the line of the fold scribe line of the thin plate, it can be made small. Prevents peeling of skew, anti-warp, and corrugated coatings. In addition, the bent part with a small drop in the groove part has almost no rough feel. The appearance of the bent part is better. There are fine concave molecules on the edge of the scribing blade to increase the density. The pressing force required by the knife is dispersed. And the biodegradable sheet with less resistance can also be easily and easily processed into a bending scribe line, and obtains good bending characteristics and flexibility according to the thickness of the sheet. In addition, even if the thin plate is folded into an acute angle, no cracks or large holes will appear, and even if there are holes, they are very small, and foreign matter is difficult to invade, which can effectively prevent the damage to commercial value and sanitation caused by this.

The example shown in the figure is constructed according to the above specifications. The following describes a method for processing 12 200424096 plastic sheet 1 using a scriber 6 and a method for assembling the plastic sheet 1 having a folding ruled line 2. First, when performing the processing of the bending scribe line 2, when the plastic sheet is ejected with the ejector knife provided with the mold, or after the ejection, use the scriber 6 shown in FIG. 7 according to FIG. 1 and FIG. 4 shows the bent portions of the front surface 丨 a, the side surface portion lb, the rear surface portion ic, and the joint portion ld of the plastic sheet 1, and the bent portions 1 e, the upper surface portion 1 f, and the lower surface portion ig. Appropriate pressure is applied according to the thickness, material, strength, and hardness of the plastic sheet 1, and the bent portions of the plastic sheet 1 are processed into bending lines as shown in Figs. 3, 5, and 6. The side surface upper part of the assembling side surface is curved, and the lower part is automatically wave-welded. The plastic sheet 1 with the bending line 2 is viewed as a rectangular container according to the first side. The front part i lb and the rear part 4 1 (5 and the joint part id, and the bending line 2 for processing the folded-in parts ie, 1 f and the lower part 1 g, and folded in an appropriate direction to connect the side part to one side. The part Id and the other side part 1 b are glued together and pushed together. The human body is pushed and fixed. The lower folded part ie, 1 f and the lower part 1 σ ^ g are bent inward and stuffed. At the gland L ^, temporarily bend the upper fold-in part le, the upper face If and 1 g outward, β listen to 'Open the container, and stuff it after packing. Packing machine (picture omitted) Yi ~ Jin It is very convenient to assemble and use an automatic cartoning machine (not shown). The ice box's joint part Id can also be welded or fixed by welding.

As mentioned above, because the plastic 4 has smaller and shallower grooves 5 on the thin plate 1, there are multiple grooves formed along the upper sides of the grooves 3 and 4 in the longitudinal direction 13 200424096. The generated stress in the surface direction is small, and it is possible to prevent the bent portion from being skewed, embarrassed, and corrugated, and to prevent the printed coating from peeling off at that portion. Moreover, the groove part 5 is smaller and shallower than the groove parts 3 and 4, and it is smoother. When you touch the bent part of the plastic sheet 1 with your hand, there is almost no rough feeling, and the feel is better. Better, superior in design. The scribing blade 6 has a smaller blade edge 9 than the blade edges 7 and 8. When pressed, the portion with a higher molecular density on the plastic sheet 1 is dispersed, and the scribing blade 6 is required for bending and scribing 2 The pressing force and the resistance resistance are greatly reduced. Even a micro-decomposable plastic sheet with a small elongation can be easily and easily processed into a bending line 2 corresponding to the thickness A of the plastic sheet to obtain good bending characteristics and Softness. In addition, even if the plastic sheet 1 is folded into an acute angle, no cracks or large holes will appear, and even if there are holes, they are very small, and foreign matter is difficult to invade, which can effectively prevent the damage to commercial value and sanitation caused by this. Bending with the sides of the bottom surface 2 b of the bending line 2 as a center, compared with the conventional bending at a part of the center of the bottom surface of the bending line, it is not easy to break, and the long groove 3 The thickness is also larger than the conventional bending scribe lines, which can ensure the strength required for bending and can be repeatedly assembled and unfolded. Therefore, the plastic sheet can be bent and assembled with machinery. Fig. 9 shows other examples of the · f fold line 2 and the scribe line 6. The groove portion 5 and the knife _ 9 ′ are formed on the groove portion 3 and the knife # 7 deeper or almost as deep as the groove portion 4 and the blade edge 8. Use a scoring knife 14 200424096 6 which basically corresponds to the shape of the groove part. In the plastic basic groove part 4 and 3, the knife is used for the bending effect in the groove part. The first part 5 and the same square shape of the two sheets are the same. The upper part of the seventh part can reach the middle. (1) Take a certain 9 example to process the bending line 2 on the sheet 1 to achieve and The same effects and effects as in the above examples. In addition, the groove portion 3 and the blade edge 7 can be formed on the groove portion 3 and the blade edge 7 which are shallower than the blade edge 8. Fig. 10 shows another example of the bending line 2 and the scribing knife. The ditch portion 7 is formed into a shape similar to a dihedral shape on the side, and the ditch portion 4 between the ditch portion $ and the blade edge 9 3 and the blade 8 between the blade edge 7 are formed.
