By the known a kind of base plate of being made up of carboard or fluting board of DE 201 03 902 U1, it has footing, and footing is parallel to each other and is left that certain distance distributes and form with the slide plate that top cover is made of one by many.Have triangle or quadrangular cross section at the foldable structure middle slide plate.

By the known a kind of base plate of DE 195 23 492 A1, it adopts the core of reels of material compositions such as paper web, floor covering as supporting member, wherein reel core double-layer overlapping and setting mutual vertically.

By WO 95/25672 known a kind of bottom board system, it is made up of a flat cap at last, and it is equipped with the tubulose slide plate.Slide plate is folded into by flat carboard.In order to strengthen slide plate, the cuboid reinforcing element of in slide plate, packing into independent, they for example by reel or favose cardboard material form.

The carton pallet of prior art shows different shortcoming aspect the big transportation volume at its little intensity or stability, manufacturing that cost is high, waste of material during with the transmission base plate.Owing to the capillarity of cardboard material, known carton pallet is subject to the damage of water and moisture in addition.

Therefore there is such requirement for base plate, promptly is easy to make, have high stability, adopts material less or that cost is low, moisture proof and water better, and itself be convenient to transport.Exist in addition the method for making this base plate and the demand of making the equipment of this base plate.

Summary of the invention

The problems referred to above and requirement solve by footing and the base plate of the present invention that is used for base plate of the present invention.The method that the invention still further relates to the method for making the base plate footing, the equipment of making the base plate footing and make base plate.

Particularly the problems referred to above solve by a footing that is used for base plate, this footing has the fiber tube of a polygon cross-sectional plane, wherein fiber tube has open region and osed top supporting region, described open region provides the interconnection that passes the base plate footing, wherein each osed top supporting region is divided into many chambers by reinforced wall, and wherein reinforced wall is made of the inwardly folding sidewall of fiber tube.

But this base plate footing at high speed and making by the polygon fiber tube easily.Because raw MAT'L is a pipe, it only need be processed, and needn't make and install additional carboard part.The rib of supporting region constitutes by the cardboard material that exists in fiber tube purely.This makes that can definitely not having waste material ground produces useless plate footing.The tubular log material is firm especially in addition, because it does not have bonding position, and punching press seam or the like, but preferably be wound into one.Cause the on the one hand firm very light again structure of the opposing party because supporting region is separated by reinforced wall in addition, it also can bear high load.

According to the present invention, fiber tube is made up of the cardboard of reeling or the Reclaimed board of coiling.Coiling by cardboard reaches extra high intensity, even also can reach with recycled writing paper the time.The application of recycled writing paper reduces material cost.

The machine of carboard and paper plant has fixing working width in addition, therefore the constantly subsidiary side production paper slip that forms when the paper of producing certain width or carboard.Same its transition region is also as waste material during this external changes in weight.These side productions or transition region paper tape are sent old paper regenerative circuit usually again back to.This brings high cost to paper plant, because side production and transition region paper tape tube are too solid, can not directly regenerate.Therefore they will be spent high expense to collapse or saw broken.

Because for the fiber tube of the present invention of reeling only needs width is narrow paper slip or the cardboard lath of about 70mm-140mm, so can adopt without a doubt when paper production and attach side production and the transition region paper tape that produces, thereby be used valuably as waste material.The side production of broad or transition region paper tape only need cut into the bar that needs width, and this can realize in paper plant without a doubt.Because otherwise the side production paper tape almost can't sell, thus they can buy dirt-cheap, if not in addition free, this reduces the material cost of base plate footing greatly.

Fiber tube preferentially has quadrangle or octagonal cross-section shape.Form the contact surface and a flat areal of support on the ground of a flat top board that is used for base plate by this shape base plate footing, the load of Chu Xianing can be assigned on the big area thus.

In the preferred form of implementation of another kind, fiber tube is made up of a kind of cardboard material by means of the sodium silicate sclerosis.The intensity of the fiber tube of band sodium silicate gives the base plate footing of being made by it extra high intensity.Sodium silicate as reinforcement and adhesives is very cheap in addition, because it only spends the price of lining cement 1/3 commonly used.Do not discharge poisonous steam when sodium silicate hardens in addition in air.During additionally fiber tube waterproof and humidity after sclerosis, so base plate also can be used in the open.

The closed area of base plate footing preferably has sidewall, and they are equipped with and are arranged essentially parallel to the impression that loading direction distributes.Compare with flat plane, impression or ripple are strengthened the sidewall of supporting region, and improve bending strength.Impression also can join mutually, thereby forms waveform.

The closed area preferentially is divided into three or four chambers respectively.Secondly each chamber of closed area preferably is of similar shape.The shape of chamber and quantity are determined the stability of base plate fatefully.The transverse force that often occurs is also particularly advantageously born in preferred osed top chamber when base plate transportation and loading except the pressure that the weight of bearing by goods causes.

Reinforced wall is folded in the folded slot that is parallel to the loading direction distribution in the preferred form of implementation of another kind.It is accurately folding that folded slot is convenient to reinforced wall.Because folded slot distributes along loading direction,, therefore the pressure that occurs is passed on the bottom surface along main loading direction so reinforced wall is arranged vertically in supporting region.

The best mutual plane of the reinforced wall of closed area is bonding.The bonding load-carrying capacity that improves supporting region greatly of reinforced wall is because the shearing force between the reinforced wall can be transmitted in bonding position.

Fiber tube preferably has a continuous upper wall and a continuous lower wall, and wherein inwardly folding sidewall and upper wall and lower wall are bonding.Upper wall that the base plate footing is continuous and lower wall are as the liner and the reinforced rib of supporting region.

The closed area has a side window mouth respectively at least in addition, so that the base plate footing is connected with a strut rail.

Particularly the problems referred to above are also by having flat basically, a flat top board and at least two base plates solutions according to base plate footing of the present invention.By adding one for example by timber, plastics, the top board that metal or carboard are formed forms a complete base plate with the base plate footing, and it can be complementary with the application corresponding occasion.

Top board preferably is made up of carboard or regeneration carboard equally.Be prepared into a complete reproducible carton pallet thus.

Footing is bonded on the top board in parallel to each other in the preferred form of implementation of another kind.

This Outer Bottom Plating preferably has at least one strut rail, and it is connected with footing and distributes perpendicular to them.The stability of base plate can be greatly improved by such strut rail, thereby the material thickness of top board can be reduced.For example the thickness of somewhat expensive top board can be reduced to about 50% under the situation of identical load-carrying capacity.Thereby can reach maximum 20% cost reduction.

Secondly strut rail can be adopted or cancel as required, therefore the bottom board system that to organize shape separately can be provided.

Strut rail is preferably made by the fiber tube identical with footing.Therefore can use identical tendon duct winding machine.

The problems referred to above also solve by the method that is used for making the footing that is used for base plate in addition, and it has following work step:

1. punching out line of cut on the fiber tube shell surface is so that downcut reinforced wall;

2. on the fiber tube shell surface, impress folded slot, so that form the folded slot that is used for folding reinforced wall;

3. folding reinforced wall is so that be divided into each chamber with the supporting region of base plate footing.

Top by the same realization of method of the present invention about the described advantage of base plate footing of the present invention.

Secondly this method has following work step in a kind of preferred form of implementation, and they were carried out before other work steps:

1. be wound into continuous fiber tube by cardboard or cardboard flaggy;

2. continuous fiber tube is cut into the length of hope, so that form independent fiber tube.

Therefore make base plate footing certain-length and that have certain intensity and load-carrying capacity from raw MAT'L paper in one approach.The coiling work step can change like this, obtains the fiber tube of different wall, obtains the footing of different bearer ability thus.

This method preferably has the work step of processing impression on the fiber tube shell surface in addition, and wherein impression is arranged essentially parallel to desirable loading direction distribution.Impression or ripple are strengthened the shell surface of fiber tube.

The work step of line of cut punching press, folded slot impression and impression processing preferably carries out synchronously.Thereby shorten the manufacturing time of footing.

This method has fiber tube is immersed work step in the sodium silicate in the preferred form of implementation of this external another kind.The paper slip that is wound into fiber tube is pulled, and passes a gluing unit, and at this moment the side with paper slip immerses sodium silicate on whole surface.Because only behind winding process, carry out " compacting-impression-punching course " immediately, just can be with sodium silicate as bonding and hardener.Reach the definitely bonding of paper by the extruding to pipe, it only just can reach by post-processing with high costs under the situation that adopts senior lining cement in common reel.Particularly the coiling of fiber tube can carry out by much higher winding speed with than commonsense method the time, because treating that bubble possible between the bonding paper slip is extruded when pipe pushes.

In the preferred form of implementation of another kind, this method has the extruding and the heating work step of fiber tube, so that fiber tube is bubble-freely hardened.Extruding and heating work step preferably and punching press-impression work step carry out synchronously.The carboard fiber remains unchanged when extruding, and the carboard surface becomes more smooth, makes footing present less wettability power thus.By heating shortened the drying time of footing in addition, thereby can carry out following process immediately.Otherwise when normal dry, to keep as many as drying time in two weeks.

This method preferably has the work step of smearing lining cement on the reinforced wall portion subregion in addition, so that reinforced wall is bonding mutually.

The problems referred to above also solve by the equipment of making the base plate footing in addition, this equipment has one and is used at the shell surface upper punch crush-cutting secant of polygon fiber tube and the pipe processing machine of processing folded slot, with one be used for along the folder of the folding reinforced wall of folded slot, to form the supporting region of base plate footing.

But by this equipment at high speed with economically by fiber tube manufacturing base plate footing.This equipment can be worked on full automaticity ground, therefore can produce large batch of base plate footing under the situation of low cost per unit.

Its deuterzooid evaluation method selecting optimal equipment has a tendon duct winding machine and that is used for producing continuous fiber tube and is used for cutting off the shutoff device of continuous fiber tube, so that obtain wishing the fiber tube of length.

Pipe tool has instrument in another kind of preferred implementing form, and it can insert in the fiber tube, and at this moment interior instrument can radially open, so that be fitted on the fiber tube inwall.

Interior instrument preferably has the removable driving surface that is used to form groove, impression and punching press or cut-out.Therefore the driving surface of instrument can be changed under the worn-down situation easily in.

Secondly instrument preferentially has at least one electrical heating elements in.Can be by heater element with the heating of interior instrument, so that therefore what impel steep water glass is the fiber tube sclerosis of wetting.Therefore fiber tube almost is under the state of " baking " or extruding.

Instrument outside processing machine has in the preferred form of implementation of another kind, they comprise the removable stamping tool and the removable coining tool that is used for impressing folded slot on the fiber tube shell surface that is used at punching out line of cut on the fiber tube shell surface.In addition, the combined action by inside and outside instrument makes fiber tube compacting in this wise, makes and extrudes the air between the fiber tube ply of paper and reach the best bonding of paper tape.

In addition, outer instrument preferably has the removable coining tool that is used for processing impression.

Its secondary device preferably has the seamed edge cutting device, in order to the vertical line of cut that distributes of punching press on fiber tube.

Folder preferably has vacuum aspirator, so that make reinforced wall outwardly-bent from the shell surface of fiber tube.Vacuum aspirator is placed on the sidewall region that fiber tube downcuts and vacuumizes, so that hold reinforced wall and can it is outwardly-bent easily.

Folder preferably has the rotation clamp of a motor-driven driving, so that reinforced wall is folded into the supporting region of fiber tube.After reinforced wall is by means of the vacuum aspirator bending, just can adopt the rotation clamp, so that reinforced wall is folded into its desirable shape.

The rotation clamp preferably can rotate by means of stepping motor, and pneumatically moves up and down.

The problem of transportation is by a kind of bottom plate making process solution with taking up room in a large number to solve base plate, and wherein the method has following work step in order:

1. form prefabrication by the polygon fiber tube;

2. prefabrication is sent to the end user;

3. at the end user place prefabrication is fixed on the suitable top board.

Because last work step is located just to carry out the end user, only just form relatively heavier base plate constantly at this.Prefabrication only occupies little space in being transported to end user's process, so shipping expense is little.A truck can load the empty base plate of 800 European base plate sizes usually.Each card can transport about 8000 individual systems when transporting prefabrication, and they are in the assembling again of end user place.

Prefabrication is footing footing or strut rail preferably, selects which kind of pre-plate for use by end user's decision, as the top board of being made by timber, plastics or carboard.He can determine the prefabrication quantity of needs neatly according to the weight of goods to be transported in addition.For example can three when light goods but every base plate is only used two footing, this means that each base plate saves about 30% material.Whether the end user can should adopt strut rail according to the different choice of load in addition.

This method has work step from top board to the end user that supply in the preferred form of implementation of this external another kind.Therefore the end user can obtain a whole set of base plate member.

Only have an appointment under the situation of the same size deadweight of 3.5kg of base plate of the present invention, European by contrast wooden floor nearly weighs 11kg.Therefore this base plate also can be operated by the woman worker.Secondly can cancel the such gas processing for the outlet defined, this impels manufacturing cost further to reduce.

Be transported on the pipe storehouse 200 from second load-transfer device 180 by means of a knock-pin 185 at fiber tube 11 on the height of article one processing line.If pipe exceed capacity, fiber tube 11 is in load-transfer device 180 ends are deposited in a warehouse (not shown) so.Fiber tube 11 can flow to second load-transfer device 180 again by another pipe storehouse 190 in the case of necessary.

The fiber tube 11 that comes out from pipe storehouse 200 carries fork 210 to be caught by a vacuum aspirator by means of first, and flows to pipe processing machine 110.Carry fork 210 to move up and Rotate 180 ° for this reason.Get vacuum yet remove, fiber tube 11 falls in pipe processing machine 110.Carry fork 210 to come back to its reference position then.

In pipe processing machine 110, begin the course of processing of fiber tube 11 now.Six pressure cylinders 130 move to " fixing " position from the right side and the left side, at this moment fiber tube is only fixing gently, but does not compress.Interior then instrument 111 unimpededly moves in the fiber tube 11 by means of gear conveyer 145.Upward pressure cylinder 135 (referring to Figure 15) are unimpededly to dropping on another gear conveyer 146

simultaneously.Gear conveyer

145 and 146 is locked, so that corresponding pressure cylinder 140,135 is applied enough antagonistic forces.Present pressure cylinder 130,135 and 140 fluid power ground or pneumatically pressurize, and move to " control position ".On the shell surface of fiber tube 11, processing all folded slots 36, line of cut 38 and impression 39 on this position simultaneously.The material of fiber tube 11 is made that by compacting so consumingly the air between the paper tape is extruded simultaneously.The electrical heating elements 113 of instrument 111 then or in starting before this, instrument 111 in the heating makes fiber tube 11 dryings thus, thereby hardens.

In fiber tube 11 sclerosis backs or behind partially hardened, make pressure cylinder 130,135,140 and gear conveyer 145,146 return to its reference position.

The fiber tube 11 of carrying fork 220 that cutting is finished by means of second then and being equipped with folded slot 36 and impression 39 is transported to folder 120 from pipe processing machine 110.Carry out the folding process of the necessity as top detailed description the in detail there.

Present footing 10 is completion of processing just, and flows to a warehouse (not shown) by means of processing line bonded assembly the 3rd load-transfer device with all existence.

Then become a base plate 1 with a footing 10 and a suitable top board 50 are bonding.Yet this final assembling work step does not preferably carry out after footing 10 is made immediately, but locates just to carry out the end user.Wan Gong footing 10 separates with top board 50 and sends to the end user for this reason.The end user can finally assemble (bonding, as to peg graft bookbinding or the like) then.Therefore transportation volume is reduced to minimum, and reduces the traffic cost that base plate sends.

Certainly base plate also can be in the directly final assembling in the originating firm there of footing 10, if the end user is unwilling to assemble.

Figure 16 represents base plate 1 another kind of preferred form of implementation.Adopt strut rail 300 in this form of implementation between footing 10, they further improve the stability of base plate 1.

The same with footing 10, strut rail 300 is made up of the fiber tube 11 of reeling.Needed fiber tube can with the identical tendon duct winding machine 150 of the pipe 11 that is used for footing 10 on produce.Need the fiber tube 11 of length to process two strut rails 300 respectively by one by punching press, system groove and impression.

Figure 18 represents that one has the lateral plan of fiber tube 11 of the line of cut 302 of the folded slot 304 of vertical distribution of impression and punching press.Line of cut 302 with fiber tube 11 be divided into one first 305 and one second 306, they form a strut rail 300 respectively.The terminal (not shown) of while cutting hard paperboard tube when die cut line 302 is so that can form tenon 310 later on, as shown in Figure 19.

As shown in cross-sectional the looking of Figure 20, the side of semihard paperboard tube 305,306 is inwardly folding along folded slot 304, so that the sidewall thickness of U-shaped strut rail 300 is doubled.Then by making double side walls locate the method for outside turnup endways, at the strut rail 300 terminal tenons 310 that form, as shown in Figure 20.

For footing 10 is connected with strut rail 300, footing 10 is equipped with side window mouth 22 in its supporting region 30, and their same punching out form, as shown in Figure 16.Tenon 310 inserts in the side window mouth 22 of footing 10 when base plate 1 and strut rail 300 are fitted together, and water glass cementation where necessary.Here the open side of U-shaped strut rail 300 to top board 50 directions, and is fitted on the top board with seamed edge on it preferably up.

The production of strut rail 300 is similar to the production of footing 10 and carries out by means of corresponding apparatus.Strut rail 300 is equally by means of pipe processing machine 110 extruding in one procedure, stamping-out, system groove and outfit impression, if it is to wish.Carry out the folding of sidewall and tenon 310 with folder 120 then.
