Description

Technical Note

The present invention relates to a Yakugawa Pallet I made from a plate-like sheet having a rigid t'l: replaced with a corrugated cardboard sheet and having a Fork Hitokawa DH II section. Background art

In recent years, pallets made mainly of cardboard sheets have been used in place of wooden pallets. Wooden pallets are always worried about problems such as harmful LU of wood blocks, excessive moisture, and wood resin, but paper pallets are not only free from such concerns, but are also homogeneous products produced at the factory. As it is light and light in weight, it is quickly becoming a pallet for export. However, since the cardboard pallet is made of corrugated pole sheet, it has the disadvantage that the strength is weak as a note. Pallets made of leg members with laminated paper tubes and corrugated ball sheets have strong compressive strength for static meta-load III ', but are pallets for products with unevenness or poor rigidity. And lack of aptitude, the use was limited. For this reason, corrugated cardboard pallets have been proposed that have been modified to increase the rigidity of the product mount (hereinafter referred to as the top plate) and to be used in a wider range of fields.

The gazette of Ι- 4-2 1 5 9 4 3 is based on the fact that a narrow girder made by folding a corrugated sheet into a trapezoidal shape is attached to a Pallets with increased rigidity are shown. However, a large number of bent girders are required to provide sufficient rigidity. Large equipment was required. Therefore, there is a disadvantage that the manufacturing cost is high.Moreover, since a large number of girders are combined in a grid, it is not possible to efficiently produce a pallet having four dimensions, and the la s becomes high. Also became higher. Japanese Patent Publication No. 87-175054 discloses a pallet formed by folding a corrugated cardboard sheet into a continuous triangle and using it as a leg member. A pallet of this shape has a strong pressure resistance, but like other corrugated cardboard pallets, the top plate only has a flat corrugated board, and the top plate has the same shape as the top plate. It did not lead to improvement of the stiffness.

Japanese Unexamined Patent Publication No. Hei 8-72 2876 describes a pallet made of so-called anglucona, which is obtained by laminating paperboard to any number of IBs and forming an L-shape as a strong material for a top plate sleeve. This pallet has improved the strength of the top plate, but Angugona is a highly pulmonary material. It uses a lot of interleaf paper and is heavy in weight, inferior in workability and strengthens the top plate. In order to do so, a large number of members were required, and it was necessary to join each one of the gluconers to the top plate, so that the resulting pallet had a serious drawback that it was very expensive.

Accordingly, it is an object of the present invention to provide a pallet made of corrugated ball sheet which has improved the drawbacks of the conventional pallet made of corrugated pole. (1) Needless to say, the compressive strength, (2) High bending strength and shear strength, (3) Use of few members, (4) Light weight, (5) Simple manufacturing, ( 6) The purpose of the koto is to provide inexpensive cardboard sheet pallets. Disclosure of explanation

The present invention has completed a pallet in which the rigidity, which is the characteristic of a corrugated cardboard sheet, is utilized to the utmost, and the illiard strength and shear strength of the top plate, which are the conventional requirements, have been modified to a human width. .

When used in a flat state, the corrugated cardboard sheet has neither a strong lili strength nor a high compressive strength. In particular, when the corrugated cardboard sheet is folded out in parallel with the step, the folding is easily done. For this reason, the conventional method of using a corrugated cardboard sheet as a top plate material in a metaphysical manner cannot significantly improve the strength of the ridge. However, when the corrugated cardboard sheet is set up vertically, both the llll strength and the pressure resistance are dramatically increased. The present invention relates to a corrugated cardboard ― Ichikawa has solved this problem by using this characteristic of the bird.

The pallet related to the first demonstration of the tree was a V-shaped slab that had an I section at ^^ of the Irikawa fork. It is a pallet that is made of a cardboard sheet, and is composed of a cardboard sheet.

According to this eleventh aspect, the W-structure break corresponds to a normal palette with a uniform width of 100 to 150 millimeters of a corrugated sheet. ), And its W-structure rest is passed through the pallet, so that a ||||

Further, according to this description, the following effects can be obtained because the fork insertion river is provided at the W structure holiday.

First, by providing the fork 忡 entrance in the W structure rest, the W structure rest roasts the top plate reinforcing material and the leg member, and the leg member can be substantially omitted. Therefore, the structure of the pallet becomes pure, so that the manufacturing apparatus is simplified and the manufacturing cost is reduced.

Second, the members equivalent to the legs of the pallet also substantially function as the top-plate sleeves, so that the I-projection strength became extremely strong. That is, generally, the stiffness of a homogeneous material such as 厲 is proportional to the square of the thickness of the material. The knives of this sword have one part per W in the W structure, and the corrugated cardboard sheet is a non-homogeneous material including an air layer, so the height of the W structure is squared. 1111 Although not reflected in bending strength, illige strength is dramatically improved because the height of the pallet is reflected in the tangential bending strength by the leg member shaping the strong material of the top plate I do.

Third, in order to use the corrugated cardboard sheet in the form of a W-structure rest, the number of walls constituting the W-structure rest is reduced, so that a pallet having an arbitrary strength and durability can be obtained. Can be made.

Fourth, by arranging the W structure at one of the special locations requiring strength, a pallet can be made with a strengthened specific location. Fifth, when the W structure is suspended, the distance from the ridge line to the ridge line of the W structure is shortened, so that the distance to support the top plate is also shortened, and the llll strength of the top plate is substantially increased. . Furthermore, if a high-density and rigid material such as plywood or plywood is used for the top plate, the I mountain ridge strength will be significantly higher.

Sixth, when stacking pallets loaded with products in multiple stages, the bottom of the pallet of the present invention is also formed from the ridgeline of the W structure rest, so the load m added to the upper pallet is Since it hangs evenly on the lower mounted product (for example, a cardboard box) through the 棱 line, there is no partial concentrated load like a pallet with a paper tube as a leg. There is no lowering. Seventh, since the opening of the Fork River where the W structure is closed can be opened anywhere in the W structure, the width and height of the opening, the spacing between the openings, etc. can be easily designed depending on the transport stage Can be manufactured.

Eighth, because the W structure is made of bent side plates of corrugated cardboard sheets, it has high cushioning properties and can protect the mounted products from various types of vibration and impact. Ideal for transporting precision parts and fragile products such as pottery, porcelain, and glassware.

The second invention of the present invention relates to a folded wire of a W structure. In other words, the w structural member is folded upward ii! I

(Hereinafter referred to as the upper fold line) and the downward fold line (hereinafter referred to as the lower fold line). The upper fold line consists of the upper liner and the half-cut line that cuts the core, except for the lower liner that is in contact with the cardboard sheet die-cutting machine.The lower fold line cuts all layers of the corrugated cardboard sheet. It consists of all W breaks and lines. Most of the lower fold line is composed of all cut lines, and the length of the transversal line is about 30 to 100 millimeters at one point, and the two right and left wings of the W structure rest are at one center fi degree It is plastic that it is placed.

According to this statement, the following effects can be obtained by providing a cutting line, a cutting line, a whole cutting line, and a partial ^ line as shown in I: in the folding line of the structural member. Wear.

First, the above-mentioned bending line makes it easy for the W structural member to fold up and down. Because it can be done simply, a W structure can be easily created manually.

Second, since most of the folded wires are composed of “sleeves”, the pressure resistance is higher than that of the normal folded wires. Third, when the W structural member is densely folded, the cut surface is formed into an exposed ^ shape, so that the mechanism for applying the adhesive to the rectangular cut metal can be simplified.

Fourth, impregnating the cut iffi with water resistant 乂 impregnating the liner and the width core of the cut cross-section by the water resistant 、 will reduce the water resistance of the pallet, the llll shear strength and the pressure resistance. Be improved.

Fifth, compared to the ridge line portion bent by a line, the cut metal has a higher adhesive strength, a larger application volume, and a better penetration and transpiration of water, so that the adhesion to the top plate and the bottom plate is improved. .

Sixth, since the bending line is a half-cut line, a full-cut line, and a partial 鄞 line, the W structural member can be punched in a single punching stroke.

Seventh, since the sheet W structure described above is provided by providing a partial fold line at the bottom folding line, later workability is facilitated.

A third invention of the present invention is to insert an auxiliary plate into the fork insertion opening of the W structure rest.

According to the present invention, when a fork is inserted into the engagement portion, the tip of the fork is questioned! The structure is susceptible to laceration when it collides with the slab cut of the W structure rest of the part. Therefore, in order to protect this metaphor, the tip of the fork can be directly questioned by inserting a sleeve aid that fits the shape and dimensions of the H mouth into the f] mouth. It can be prevented from contacting. When the fork is inserted into the mouth at an angle of ίΦ, the fork is inserted while sliding along the ifii of the sleeve aid, so that the cut surface at the opening is less likely to tear.

Furthermore, according to this Π Π sword, the auxiliary material is made of a corrugated cardboard sheet of one shape, and the cut surface of the opening is supported by r shapes, so that the strength of the auxiliary material against external pressure is improved. Improves I-strength.

If the material of the auxiliary material is a corrugated sheet, the completed pallets will all be pallets made from corrugated sheets. According to a fourth description of the present H-sword, the auxiliary material has two or more shape retaining wings toward the upper side or the left and right sides, and the shape retaining wings are connected to a W structure at an interfacing portion. It is to insert into the empty question formed by. The ridge spacing of the W-structure rest is fixed by the shape-retaining wing inserted into the air gap, so that the bending strength, the pressure resistance, and the shear strength are stable against external pressure. That is, the predetermined W structure can be maintained without fixing the W structure to the top plate or the bottom plate with an adhesive.

According to a fifth aspect of the present invention, the shape of the three ports is changed from a rectangle to a trapezoidal shape in which triangles protrude from both ends of the opening (hereinafter, referred to as a trapezoidal opening). By setting it as an interrogation part, the strength of the I river and the pressure resistance can be improved.

According to a sixth aspect of the present invention, the W structure rest is sandwiched between a top plate and a bottom plate in which side wall flaps having openings corresponding to the openings of the W structure are continuously arranged on four sides. The side flap is folded and the corresponding top flap side wall flap and bottom flap are joined to form a pallet with a box shape (hereinafter referred to as a box-shaped pallet). is there.

According to a seventh aspect of the present invention, there is provided a method according to the sixth aspect, wherein, of the side flaps provided on the four sides of the sixth aspect, the side flaps having openings at front and rear of the pallet are removed, and the top plate and the bottom plate are removed. It is said that the side wall flaps are provided only on the left and right sides. The W structure is sandwiched between the top plate and the bottom plate, and the side wall flap of the top plate is folded into r shapes, and the side wall flap of the bottom plate is folded into an ^L shape, and then protruded. The corresponding side wall flaps are joined together.

The flaps on the left and right side walls of the 6th and 7th swords greatly increase the shear strength acting in the fork insertion direction (front-rear direction) of the pallet. : Pallets can be prevented from being damaged due to damage such as vibration during transportation, sudden braking, and impact underneath.

The Η sword of Section 8 of this II sword is constructed by connecting the notch member of Part I (hereinafter referred to as the extra notch), which had been discarded as notched waste material, to the 则 plate of the W structure rest. It is to bend in the direction of the top plate as it is. If the half-cut line of the extra notch connected to the side plate of the W structure rest is a medium fire on the side plate of the W structure rest, the 線 line position of the notch extra part cut in the direction of the top plate is This position coincides with the ridge line position of the W structure on this holiday, and the lill strength and pressure resistance are greatly improved. The use of materials that previously required time-consuming disposal greatly contributes to the strengthening of the pallet.

According to a ninth invention of the present invention, a plurality of rows of Yanagawa notches (hereinafter referred to as Yanagawa notches) are provided so as to be perpendicular to the ridgeline on the top plate side of the W structure, and the fork is provided from the ridge direction of the W structure rest. A two- or three-strand W structure is arranged in parallel with a space where a string can be inserted, and a beam member made of a corrugated cardboard sheet is inserted into one notch of the Yanagawa.

According to the present invention, the llll strength in the direction perpendicular to the ridge line of the W structure can be increased, so that a four-sided pallet can be easily formed. According to a tenth aspect of the present invention, in the pallet comprising the W structure, the W structure is a W structure without notching an opening of a fork insertion river, and the W structure having no opening is provided. Or a pallet consisting of three sets arranged side by side with a space for the fork to be inserted, forming a pallet and a leg member of a software, and joining a top plate and a bottom plate vertically.

In the pallet according to the present invention, the W structure rest is used as a leg member of a cardboard pallet, but since the top plate uses the cardboard sheet as it is, the llll strength is reduced through the opening. Although high strength and strength are not obtained like the body's llll strength, the ridgeline of the W structure that forms the leg member can be extended to the entire palette, leaving the insertion hole of the fork insertion river, Substantial llll strength is improved. The pressure resistance of the pallet can be arbitrarily controlled by increasing or decreasing the number of sides of the W structure.

The first aspect of the present invention of this ¾ Ming, the bottom plate there is no sleeves shaped box of屮, houses one of the pallets Bok out of f _t d Ming Paretsu Bok made of W structure holiday, Roh, 'This is to let the let and the box rest. It has the following effects.

First, in order to store the pallets in a sleeve-shaped box, the top of the pallet can be used as the bottom of the box. Therefore, not only can the bottom of the box be omitted, Simple box! j Can be tied up.

Second, if the boxes and pallets are rested, the pallets will become less shear and | extruded, and at the same time their H-resistance will be improved. As a result, the I-strength I and the shear strength I of the pallet rest to be stored do not need to be ignited, and the amount of material used is small.

\ 3, in the pallet with a regular wall flap installed at iVi i & 扳, the 壁 wall flap is folded outside the upper iid box and joined to ii. The sleeve box and the pallet can be easily integrated.

The twelfth invention of the present sword is to make a pallet having the above configuration by using a rigid book material other than a cardboard sheet.

In other words, for any rigid thin plate material, the above effect can be achieved by providing an opening in the book board and folding it into a W structure and joining it to the top plate and bottom plate, regardless of the material. Can conduct.

As described above, the pallet using the W structure according to the present invention has a strong I girder strength, compressive strength, and shear strength, and has an arbitrary strength by increasing or decreasing the number of side plates. It is a pallet that can handle various dimensions. In addition, the pallet is small because of the small amount of raw materials used, and the structure is simple, so the production cost can be reduced.

In addition, although this specification W does not specify 0 for the direction when using corrugated cardboard sheets, the steps' and j to be used can be determined according to the characteristics and pallet dimensions required for the nozzle. . In other words, in Palette 1, where the compressive strength is required, the stage I of the W structure break must be passed A to the top and bottom. Although the strength is not so much needed, the pallet which is viewed from the viewpoint of the llll strength III is a fire. If the pallet is fired, use a step with the step parallel to the ridgeline. , And the folding of the W structure rests in the machine direction, so that one corrugated sheet can take a large number of boards, so the manufacturing cost can be reduced. Can be.

Also, the material of the corrugated cardboard sheet is JM if the kind of liner core (quality, basis weight, etc.) is selected according to the quality characteristics required for the pallet. — Fruits can also be selected from the types of breeds available on the market (A, B, C, E, H, etc.). Further, depending on the strength, a cardboard sheet such as a double-duplex or double-duplex can be selected at any time. In addition, the leaf base paper Ya La Mine one Bok base paper with a water-resistant, polyacid de base paper, such as a strong cardboard Paretsu me by go-between humidity and water to be used as a cardboard Sea Bok of the material _(the further, stage Borushi one The pallets of various strengths can also be obtained by binding various types of rigid materials to each other.

Best mode for carrying out the explanation

In order to describe the present invention in more detail, it will be described with reference to the accompanying drawings.

FIG. 1 shows a perspective view of the pallet 1 according to the first invention of the present invention, and FIG. 2 shows a side view thereof. It has a simple configuration in which the top plate 110, the W structure 120, and the bottom plate 130 are joined from the top of the pallet 1 only with an adhesive.

The basic structure of the present invention resides in the W structure 120, and FIG. 3 shows a W structural member 1221, which is an expanded drawing thereof. W structural member 1 2 0 1 has a fork insertion river notch 1 2 0 9 (opening 1 2 0 a) which is ffled at all cut lines 1 2 0 7 and 1 2 0 8, and W structural rest 1 2 0 It consists of an upper fold line 1202 and a lower fold line 1203 for folding, and they are formed adjacent to each other alternately. In addition, the bending direction of each bending line may be opposite to each other, and if-, the symbols of the folding line and the cutting line in the subsequent drawings are opposite.

Folding the W structure material 1 201 into |||| fold lines 1 2 0 2 and 1 2 0 3 results in a W structure 1 2 0. Note that the W structure rest 120 is constituted by side plates indicated by the symbols ^ 1 205 and 1 206. (In order to avoid complexity, the same symbol is used hereafter, 125.)

Since the strength of the pallet 1 is determined almost proportionally by the number of side plates 125, it can be arbitrarily controlled by increasing or decreasing the number of plates 125 of the W structure rest 120. The strength of (则扳 125) is determined by the material type of the corrugated cardboard sheet and the type of the flour. It can be easily estimated from the column crush strength of the board and the overall ring crush of the base paper.

However, since the W structure 120 has an opening 120a in the side plate 125, the strength of the pallet 1 varies depending on its shape. That is, as shown in FIG. 4 which is a front view of the W structure 120, the height H of the W structure 120 (the height H of the W structure 120 is The length L of the side plate 125 is represented by the height H of the W structure in order to avoid complication in the future because the length L is almost the same as the length L of the opening. The bending strength varies depending on the opening width w 1 and the like.

The bending strength of the pallet, which is the greatest feature of the present invention, increases as the height H of the W structure 120 increases, and decreases as the height h i of the opening increases. That is, as the height h2 of the top plate reinforcing material, which is the difference between the height H of the side plate 125 and the opening h1, the bending strength increases. The pallet made of step poles is made of an inhomogeneous material including an air layer, and cannot be applied unconditionally due to the effect of the two openings formed in the center of the pallet. It is proportional to the square of the height. That is, in the pallet of the configuration of the present invention, since the heights H and h2 of the W structure 120 are high, the bending strength is dramatically increased.

In addition, the bending strength depends on the height hl of the opening, the opening width w1 of the opening 120a, the distance w2 from one opening 120a to another opening 120a, It depends on the distance w3 from the edge and so on, so it is necessary to experiment to know the detailed bending strength.

When making a pallet with high pressure resistance, the corrugated cardboard sheet is used in the vertical direction, but this direction is the width direction of the corrugating machine. The integer of the value obtained by dividing the limited corrugated board sheet width by the height H of the corrugated board is the number of side plates 125 that can be collected from one corrugated board sheet. Therefore, only a limited number of side plates 125 can be obtained from one W structural member 1221, and the pallet strength is limited. However, by using two or more plural W structural members 1201, almost any number of side plates 1205 can be obtained, so that the pallet can have any strength. . Furthermore, the ridgeline of the side plate 1205 adjacent to the W structure 1205 ¾Since the gap w4 between the cuts 1202b is short, the effective strength of the top plate 110 is high. Become.

In addition, the width of the opening 120a of the W structure 120 depends on the size of the fork and the transport method, and the width w1 of the opening 120a and the distance w2 between the two openings 120a. And the height h 1 can be arbitrarily designed.

The second sword of the present invention relates to a folded Ifll wire of a W structural member 1221, made of a corrugated cardboard sheet. FIG. 5 is a perspective view of the W structural member, and FIG. Place a perspective view of the body. The folding line of the present invention consists of an upper folding line 1 202 and an upper liner 1 consisting of a half-cut line obtained by cutting the upper liner 11 and the core 12 except for the lower liner 13 of the cardboard sheet. It consists of a lower fold line 1203 consisting of the entire cutting line cut from 11 to the lower liner 13 and a 鄞 line 124.

According to the present invention, the upper folding line for bending the W structural member 1 201 into a Λ shape

Since 1202 is a half cut line 120c, it can be easily folded upward. The half cutting line may partially include the entire cutting line.

Furthermore, since the lower fold line 1 203 that folds the W structural member 1 201 into a V-shape is a complete cut line 120 b, the upper liner 1 1, the core 1 2, and the lower liner 1 1 3 Has been cut, and the bottom line 1203, which does not contain the entire cutting line 120b, has a ^ line 124, so that it can be folded down easily. Can be. The 鄞 line 124 may be any portion on the V-shaped fold line 1203, but it is desirable to have two places at the left and right or one place at the center. The length of the wire 124 differs somewhat depending on the material type of the corrugated cardboard sheet, but it is desirable that the length of one point is about 60 mm.

Further, since the W structure 120 can be folded into a rectangular column shape in which the wall surfaces of the side plates 120 5 are in close contact with each other, the upper and lower cutting structures 120 B of the W structure 120 can be formed. , 120 c can be easily coated with an adhesive. Cutting surface 1

The shape of 220b and 120c is honeycomb, and when the adhesive is applied to the sections 120b and 120c, the adhesive is cut to 120b and 120c. Enter inside As a result, the material near the cuts 120b and 120c is strengthened by the effect of the adhesive, and the ll! -Strength, pressure resistance and water resistance are improved.

In addition, the cut surfaces 120b and 120c of the W structure rest 120 have a larger cutting area than the line ridge line 120e bent by the line 124, and are bonded.剂 is easy to ride, and the adhesion to the top plate 110 and bottom plate 130 is improved.

Further, since the cut portions 120b and 120c have a sleeve shape, the pressure resistance can be increased as compared with the ridge line portion 120e folded by the ^ line 1104.

In addition, the W structural member 1201 can be cut out of the upper fold line 1202, the lower fold line 1203, the 鄞 line 1204, and the opening 120a by one punching. The punched sheet becomes a continuous sheet.

According to a third aspect of the present invention, an auxiliary plate 340 made of a corrugated ball sheet is inserted into the opening 120a of the W structure 120, and FIG. FIG. 8 is a perspective view of the developed view of FIG.

According to the present invention, when a fork is inserted into the opening 120 a of the W structure 120 of the pallet 1, the fork is cut out of the opening 120 a in a cut-out section 120 7, 1 208. When it comes into contact, the notched sections 1207 and 1208 have a structure susceptible to tearing. Therefore, in order to protect the cutouts 1207 and 1208 of the W structure rest 120, the auxiliary material 3400 having a one-piece shape matching the shape and dimensions of the opening 120 a is provided. The fork is inserted into the opening 120a to prevent the fork from directly contacting the notched sections 1207 and 1208. Also, the fork is connected to the wall of the auxiliary member 3400. When the fork is inclined at an angle of 401, the fork is inserted while sliding along the ceiling JI: 3401 or the side wall: 3402, so that damage to the W structure rest 120 is greatly reduced.

Furthermore, according to the ¾ ¾, the auxiliary material 340 is supported by the notch 2 1 2 0 f of the mouth 1 2 0 a, interval w 4 is ϊ ^[:. for always maintained, llll up strongly ίί and resistance to U: the strength is improved.

The fourth sword of the present invention is one in which a shape retaining wing 4304 is provided on the auxiliary material 3400 of the third sword. Pallet 1 W structure 120 FIG. 9 shows a perspective view in which the auxiliary material 4304 having the 430 is inserted, and FIG. `` A plurality of shape-retaining wings 4304 are provided above the one-shape auxiliary material 4330, and the shape-retaining wings 4304 are provided from the notched gap of the opening 120a. By inserting it, the opening section 120 f of the W structure 120 is fixed, that is, the W structure 120 is not fixed to the top plate 110 or the bottom plate 130 with an adhesive. As shown in the development of FIG. 10, the shape retaining wings 4304 can partially cover the ceiling material 4301 with the W structure 120. Cut out along the notch line 4305 in accordance with the shape and dimensions, and bend it along the 鄞 line 4303 to make a protruding shape retaining blade 4304.

Fig. 11 shows a perspective view of the W-shaped retaining wing 4304 extending to the left and right and inserted into the opening 120a of the W structure 120. Same as the fruit. At this time, the protruding shape retaining blade is cut out from the side wall 4302 of the auxiliary material 4300.

The fifth invention of the present invention relates to the opening 5200a of the W structure 520. FIG. 12 is a perspective view of the pallet 2 of the embodiment. In the pallet 1, the shape of the opening 120a is rectangular, but the opening 420a of the present invention has a trapezoidal shape. According to the experiments of the present inventor, a rectangular (width 250 mm, height 65 mm) opening 120 a at both ends of an upper side of the upper side 150 a width 15 mm and height 30 mm The pallet 2 having a trapezoidal opening 502 a with a protruding triangle has significantly improved bending strength and pressure resistance compared to the pallet 1 having a rectangular opening 120 a.

FIG. 13 is a development view of the W structure 520 of the present invention. The upper folding line 5202 and the lower folding line 5203 are provided so as to be opposite to the folding lines in the developed view of FIG.

The sixth sword, the sixth sword of the present invention, is provided on the top plate G101 and has a lid 611, which includes side flaps 6102 and 6103 and a glue allowance 6107. 0, and connected to the bottom plate 6 3 0 1 to form a body 6 3 0 consisting of side wall flaps 6 3 0 2, 6 3 0 3 and glue allowance 6 3 0 7, and a body box 6 3 0 W A pallet 3 which houses the structure 6 20 and covers the lid 6 10. FIG. 14 shows a perspective view of the notebook 3, FIG. 15 shows a perspective view of the lid box 61, and FIG. 16 shows a perspective view of the body box G 30.

According to the present invention, a height 630 and a lid 610 are made, and a W structure 620 is put in the height 630 and the lid 610 is covered. Palette 3 can be created easily.

The seventh aspect 11 of the present invention is that, in the pallet 3, the side wall flap 6103 before and after the lid 61 0, and the 0 W wall flap after the height 63 0. 6 3 0 3 missing, top plate 7 1 0 1 connecting side wall flap 7 1 0 2 and bottom plate 7 3 0 1 fast connecting side wall flap 7 3 0 2, glue to ridge line After storing the W structure rest 720 which hesitated, the side flaps 7102 and 7302 are folded II and the corresponding side flaps are joined together. FIG. 17 shows a perspective view of the knurl 4.

According to Kizaki Akira, the pallet is completed simply by folding and joining the flaps 7102 and 7302 to the top plate 7101 and the bottom plate 7301 Therefore, it is a pallet suitable for a single-movement pallet manufacturing machine.

A pallet without side wall flaps, such as the knurl 1, has a much lower strength when the fork insertion force | tJ is compared with the shear force on the left x side of the pallet. Not. However, as shown in the pallets 3 and 4 of the water of ^ 6 and 7 側, the side flaps 6102, 7102 and 6302, 73 connected to the top plate and bottom plate By joining 02, the shear strength in the fork insertion direction can be changed to human.

Wood ¾ HJJ ^ 8 ll! Ij is a tiger lumber that is usually shown as a notched deer wood in the I section 820a of the W structure rest 820 a. Part 8 210) is used as the top plate sleeve material in Icheon. Fig. 18 shows the metaphysical diagram of the LET 5 and part of the perspective view of the W structural member 8 201 strengthened by the notch 8 The 20 perspective view is shown in Figure 20.

As shown in the perspective view of the W structural member in Fig. 19, the center of the part that was flfled by the half cutting line 8207 and the entire cutting line 8208 was cut by the full cutting line 8209. The remaining notches 8 2 1 0 and 8 2 1 1 (represented by 8 2 1 0 in the future to avoid complexity) will correspond to the side plates 8 2 0 5 and 8 2 0 of the W structure rest 8 2 0 6 (In order to avoid complications, the side plate will be represented by 8205 in the future.) In addition, the prayer will be bent on the top plate 8101 while being installed with a broken line 8207.

In the pallet 5 of the present embodiment, the bending strength and the pressure resistance are reduced by using the notch margin 821 of the opening 820a as described above. Is improved by more than 20% compared to the strength when Icheon was not used.

Furthermore, according to the present invention, since the notch surplus portion 8210, which was conventionally cut off and discarded, is used, the strength is improved by using the W structural member 8201 without leaving it. In addition, the problem of discarding waste materials can be omitted.

According to a ninth invention of the present invention, a two- or three-string W structure 920 is arranged in parallel at an interval where a fork can be inserted, forming a four-sided pallet. FIG. 21 is a perspective view of the pallet 6 in which a pair of W structures 920 are arranged in parallel, and FIG. 22 is a developed view 920 of the W structure 920.

Directly to the top-side ridgeline 9200b of the W structure rest 920, two rows on both sides of the pallet and one row at almost the center, a total of three rows of Yanagawaguchi 920h, 9 20 i, 9 20 h (In order to avoid complexity, it will be represented by 9 20 h in the future.) 3 sets of notched rivers with cutouts The members are arranged in a row with iiil gaps between them, and the beam members of the three arrested members are joined to Yanagawa Ri 920 h and then joined to the top plate 9 10 and the bottom plate 9 30 . In the pallet 6 of this study, the fork can be inserted in the direction of the opening 920a and in the direction of the lateral opening 920y. It becomes a four-sided pallet.

In other words, for the insertion from the direction of the opening 920 a, the W structure with the W structure rest 920 is used. High beam strength can be obtained by the beam member 990 folded into a W structure made of corrugated cardboard sheet inserted at 920 h. It should be noted that the illi strength of the beam member 990 depends on the number of side plates constituting the beam of the beam member 990, the bending height, and the configuration of the corrugated ball.

In addition, in the case of the nozzle 6, if the opening 920a of the W structural member is used without being cut, the fork can be inserted only from the direction of the lateral opening 920y. It becomes a pallet. Pallets of this type can easily be made large pallets up to the size of the corrugated sheet. Compressive strength can be controlled by the number of side walls of the W structure, which is a leg member, and bending strength can be controlled by the number and height of beam members.

The beam member 9900 consists of an upper fold line consisting of a half-cut line 9902 and a lower fold line consisting of a full-cut line 9903 and a 鄞 line 9904. Is shown.

The 10th development of the present invention was a simple folding of a cardboard sheet without notching the beam opening 920 h in the pallet 6 and using no beam member 990. The leg member 102 is a variable two-way pallet 7 sandwiched between the top plate 101 and the bottom plate 103 and joined. Figure 24 shows the oblique j¾ diagram of Palette 7 in the process of being accused.

ADVANTAGE OF THE INVENTION According to this invention, although it is a simple structure which consists of a leg member 1020, a top plate 1101, and a bottom plate 1031, a pallet with strong pressure resistance can be obtained. In addition, since the distance between the leg members can be reduced to an allowable range in which the fork can be inserted, the sudden llll strength j £ can be increased.

Furthermore, since there is no top plate reinforcing material h2 shown in FIG. 4, the fork insertion height can be increased, and the pallet can be easily loaded and unloaded. The pallet 7 of the present invention [1JJ has low strength against the force applied to the left and right directions of the pallet. Therefore, it is preferable to arrange the side wall flaps 10 13 and 10 33 and join the corresponding side wall flaps.

The first investigation of the HJJ of this invention was that the bottom of the box was cut open as a fork opening at a position corresponding to the opening of the fork insertion river at the bottom of the pallet. One of the pallets 1 to 7 according to the embodiment of the present invention is housed in a sub-block B provided with a pallet, and the pallet and the pallet B are integrated.筘 B has an open bottom, so various types of pallets can be formed depending on the type of pallets to be stored in the sub-b of the box B. An exploded view of let 8 is shown in Figure 25.

Box B in Fig. 25 is also an open box at the top of 筘, and the cover Y is shown as a box that covers the box B from above.パ The pallet 11 stored in B is a W structure rest 1 1 2 between the top plate 1 1 1 1 and the bottom plate 1 1 3 1 with the side wall flaps 1 1 3 2 connected in the left and right direction of the pallet. It is joined by sandwiching 0. Side wall flap 1 1 3 2 With pallet 1 1 2 open, cover box B from above, and then bottom plate of pallet 1 1 attached to the bottom of outer surface B 1 of box B Fold the side wall flap 1 13 2 at the line 1 1 3 4 [The pallet 11 and the box B are integrated by joining the outer surface B 1 of the box B with an adhesive or a gum tape.

The following effects can be obtained by integrating the pallet with the box. First, since the pallet 11 is stored in the box B with an open bottom, the top plate 110 of the pallet 11 becomes Kanekawa as the bottom plate of the 筘 B.筘 The bottom plate of B can be omitted.

Secondly, since the box B and the pallet 11 are closed, the shear strength of the pallet is greatly improved, so that the shear strength of the pallet 11 does not need to be considered so much. .

Third, by joining the side flap of the pallet 11 and the outer side of the box B, the rest can be easily made.

In addition, in the figures from 1 to 25, the same palette is In the drawings, perspective views, metaphysical diagrams, etc., there are some dimensions, the number of sheets, etc., which are given forces ^s , omissions and simplifications, etc. In, mutual drawings and figures are designed and created in relation to each other. Industrial applicability

As described above, the pallet according to the book has an overweight due to the provision of the opening on the W structure rest, the illicit rigidity of the top plate has been dramatically improved, and the pallet mounting surface has been strengthened. It is possible to provide a pallet made of corrugated cardboard, which can deal with products with high fluidity and has a simple structure.
