DE102008018674B3 - Vertical cutting machine for foamed materials, particularly polyurethane flexible foam, has cutting portal movable on two tracks, where cutting portal has endlessly revolving cutting tool, two work benches and two side catches - Google Patents

Abstract

The vertical cutting machine has a cutting portal (6) movable on two tracks (7). The cutting portal has an endlessly revolving cutting tool, left and right work benches (2,5) and left and right side catches (1,4). The cutting portal is movable transverse to the feed direction of the foamed material. The cutting portal is moved into work benches of different lengths by similar work length from the work area. The entire work surface of both work benches is free so that both side catches are moved left and right in arbitrary over the entire work width of both the work benches.

Description

It is a vertical cutting machine for foams and other materials (the after conversion the cutting tool used constructively for other materials can be) according to the preamble of claim 1. In particular Polyuretan soft foams are cut to composite foams. following is here from the above-mentioned, above-mentioned foam block spoken.

The following vertical cutting machines are known from the prior art:
From the EP 0 390 939 A1 a vertical cutting machine is known in which the cutting unit arranged parallel to the two side stops and the right and the left table are designed to be the same length. These side stops are each movable only across the width of a work table.

From the DE 2052219 A a vertical cutting machine is known in which the side stop can push the material aerated concrete over the center of the table. Other functions do not fulfill this page stop. For transport, in one direction, serve tracks or moving belts.

Furthermore, from the JP 06320483 A a vertical cutting machine known, are arranged in the 2 side stops. With the same table surface, these can each be driven up to the knife gap. The side stops themselves can be moved vertically upwards or vertically downwards by a turning device. In addition, this machine has a turntable centered in the left center of the table.

Besides that is from the DE 1770623 U a cutting machine for cutting fabrics known in which, also centered, a turntable is arranged in the work table.

Finally, out of the DE 2207196 A a vertical cutting machine is known, which is characterized as follows:
In this vertical cutting machine 2 work tables and a cutting portal, transversely to the feed direction of the foam movable, with circulating band knife, arranged.

In the DE 2207196 A At the same time, the left worktable represents a turntable. This conventional turntable works as follows:
On the left work table a stop is firmly anchored and that at the outer end of the turntable left. It can not be opened upwards by 90 °, nor can it move independently, independently of the turning process of the turntable. There is no tilt stop on the turntable.

The Left turntable can be opened by a foot pedal (pneumatically operated). Of the left table leads then about 500 mm to the left. After that, the turntable can be hand-held with corresponding physical Power expenditure by 90 ° after be turned right. At the same time this causes the one on the left Firmly anchored table fixed left stop in the same direction by 90 ° and is then behind, d. H. left behind the bandknife located. Another turn to the right or from the starting position to the left is structurally not possible. The turntable itself is located on a substructure, on which a turntable is mounted is. The substructure (eg the outer "legs") of the turntable remains in his position. The table is thus turned on the base.

The Consequence of such a construction is that the left stop by the rotary movement of the turntable is rotated with and at the end of the turning process after all outside of the table area is left behind the band knife. Thus, the left stop in the rotated state - so stop rear left from the knife - not for transportation of the cuttings are used.

To execution This 1st intermediate step is the way to load the left workbench free. Without the (obstructing) left side stop can be the table surface Loaded with the foam block by placing a stacker now to the outside end the left turntable moves and unloads.

After that can the left table in a 2nd intermediate step (with renewed effort) be turned back to its original position.

at turning the turntable (open and close) the knife is exposed. Main danger: The operator of this turntable This can be due to the band knife open during the turning process inflict very significant injuries. This also applies to Third parties who may help to turn the table. Then you can the left table again pneumatically by foot pedal to the other table be approached.

Of the left stop is now back in its starting position on the left side of the left side of the table.

The above-mentioned 2 intermediate steps are used exclusively to get the foam block on the table of the machine and that with proper operation. However, since these intermediate steps are very time-consuming, there is a risk that the machine operator omits these and the foam block with force Hand carried to the table and then moved to the knife position. This is very dangerous in relation to the band knife. There is also the risk that z. B. with a forklift the machine (in the closed state) can be damaged.

First after turning back and closing the Turntable can then foam block with the left stop be pushed on the right table. There he will be at the right Table attached, located on the right head plate pushed (with it the block is just resting; constructive is such a head plate not mounted on the turntable). Again, this requires physical Effort.

To note: the foam block on the turntable was However, by the above-described rotation also to the left turned. The original outer right Side of the foam block (which after turning 90 ° now from the Knife is turned off) can not therefore with the subsequent cutting operations to be cut, what is significant and what to come back to is.

Of the left stop is now on the right table. The right stop is then from the right also to the foam block on the right Brought table and that first in manual mode via a so-called "4-way switch" over the Knife gap. Promoted on it the right stop the foam block.

Becomes this shift process continues to the left, so the block continues to Band knife guided, Although the foam discs are cut. They are but then after the respective cutting operation on the left turntable, but without being able to be rotated. In this state can namely only parallel cuts are made by the band knife. Therefore must be with proper operation in a 3rd intermediate step, this turning device again - before the cutting process is started - to be turned by the left stop to the extreme Driven to the left and then the turntable is opened by 90 °, so that then the stop on the opposite rear side of the left table is located. Only then can with this construction after execution the cutting program used the left turntable and the cut Foam material 90 ° once turned to the left and then cut crosswise.

Of the Operator then writes his program, as does the foam block should be cut, z. B. 10 pieces a. 200 mm. Then start he the automatic for the stop and the knife, with the unit on the opposite Side, so behind stands. Then the right stop puts the foam block in the given way too. The unit moves and the band knife cuts the discs as programmed.

To execution the cutting process must be the right stop from the area of the kerf moved back to the right become. The gap for the band knife is thereby exposed. The clippings are located on the left table. It was fed only with a stop, namely the right stop, because the left stop still with the turned table - on the across from lying side - behind, located behind the knife. The cutting unit is on the back side.

Now In a 4th intermediate step, the left table is opened again and rotated 90 ° and then closed, so only now the left stop again can be used. Through this process is the foam block (cut) once turned to the left by 90 °. But that means as mentioned, that at the beginning (as a result of the 2nd intermediate step) not cut Side of the foam block is again moved by 90 ° to the left to the stop has been. The non-cut side is thus around 90 ° after Turned left now on the opposite side of the table in front of the left stop. The distance to the knife is extremely close both when extending and retracting the table.

Now will over the left stop the material again to the knife gap to the right driven to the knife gap. At the same time the right stop brought in the direction of the knife gap. Only now can the block of 2 attacks (left and right). Then the new program is entered, so that the lateral side can be cut. It is pushed from left to right. The finished cut material is therefore no longer on the left, but now on the right table.

Around being able to unload the material, it is necessary, this by means of the right stop on the left To push table, but only about 35 mm is possible. Then you have to go in one 5. Intermediate step, the left stop be put aside again (otherwise it blocks the unloading), which is done manually by a handwheel to operate or by an electrical device happens. First when the left stop is then rotated 90 ° to the right again, is the work surface then from the outside accessible. Only this makes it possible it then to unload the material. The cutting tool (knife) lies here free.

After this the first cutting process performed and the turning process after left has been carried out by means of the left turntable is located the previously sliced foam, turned left, on the opposite Side of the turntable towards the stop. This site is not yet been cut and can also by means of the before described construction and the program will not be cut. Because the further cutting process is always only right with straight Cuts performed.

If Therefore, all pages neat it should be cut, so it is necessary, that in a 6. Intermediate step (practically before any other intermediate steps the 1st intermediate step would be) from the beginning the first page of the block is cut clean, because they then after the first operation described before then on the other half of the table left to stop. This page is with silicone oil or talc Mistake. Cutting off this "polluted side" would be possible if the operator on the table of the machine rises and with force push the not yet cut block to the band knife. The weight of such a block depending on the quality about 120 to 200 kg. In the face of (running or free standing) Bandmessers result from this quite significant dangers for body and Life of the server or helping third party and things.

It follows that there are several shortcomings when using the conventional vertical cutting machines with turntable:
The entire table, including the left stop, must be moved away by hand and rotated by 90 °, in order to be able to unload the foam block on the table, which is time-consuming and therefore cost-intensive (1st intermediate step). Since at the same time the band knife is exposed, there are considerable dangers for life and limb as well as things.

Of the Turntable only moves 90 ° once and then can not once and repeatedly by 90 °, but only once rotated 90 ° back, so a trimming (Straight cutting) of a foam block on all 4 sides not hereby possible is. If the cut sides are not exactly right-angled, this is true then for the subsequent cutting operations and for that the clippings. An exact right angle and straight cut is not guaranteed. For cutting all sides are time consuming and costly as well dangerous 6 intermediate steps necessary.

The described method of operation carries the further danger, that the operator in knowledge of these circumstances after the first intermediate step with force the block first to the band knife pulls to this 1st side (which in consequence of the rotation otherwise without this Cut unclean to the left stop would be) to prune in advance. hereby the operator assumes the danger of considerable injuries to the bandknife out, especially if he does so on the very smooth machine table increases.

One Another disadvantage is that when using this conventional Turntable the left stop to transport the foam block can only be used after the 2nd intermediate step, if the Material not improperly and in a hazardous manner on the Stroke lifted or dumped sideways and on the table has been pushed. The table is here for convenience or time reasons not open, exists at the same time the risk of damage the machine z. B. by a stacker. Moreover, this is a physical Force required to position the block. It can not be excluded that the operator for this purpose the working table of the cutting machine rises, which while running or standing band knife biggest dangers for body and brings with it life.

In addition, can the left stop is only used again after the 4th intermediate step come, which is very time-consuming in the production process and therefore is expensive.

at The technical situation described above therefore remains only the Recital - to the to cut the first side of the foam block in advance - that the Foam block after unloading on the table from the operator of Hand turned and cut first. This cut so Page would be then at the end left to the stop. Only with such an approach would be guaranteed that all 4 sides are clean cut. However, this is simultaneous to take into account that the 90 ° angle not sure about this procedure. Who by hand Moving a block, that can not do so exactly that then the 90 ° angle is complied with. this leads to then continue that inaccuracy in the clippings continues so one over the diagonal measured accuracy can no longer be given.

One exact right-angled cut is in this construction of the thus explained above not guaranteed.

apart Of these, such an operation is because of the open band blade very dangerous and again requires considerable effort.

The invention is based on the object to provide a vertical cutting machine, which eliminates the time-consuming and physically strenuous repeated turning away the left work table with left stop for the purpose of loading and unloading the work table.

Further the task was to create a vertical cutting machine, around rectangular or square material on all 4 sides like that to cut, that always exactly right-angled cuts are possible.

The The object is achieved with the features specified in claim 1. advantageous Embodiments are given in claims 2-4.

Construction of the vertical cutting machine according to the invention:

Cutting portal as well as right and left Work table:

The Cutting portal is running on 2 taps (rails). They are each 4000 mm long, 80 mm or 100 mm wide and 160 mm high. The cutting portal has the form of a open U-profile with the length dimensions of 3100 mm (top cross) and 2600 mm (vertical) and 3100 mm (cross under the right work table). It consists of folded 6 mm strong steel sheets with a respective width of 460 mm and a respective depth of 150 mm. The rigidity is determined by the Incorporation of 12 min thick steel plates increased. Located in the cutting portal The revolving, endless band knife, the 4 located therein knife rollers guided and by an electric motor (4 Kw brake motor) is driven. This Band knife exits top left from the cutting portal and then runs through the knife gap vertically downwards (the left and right Worktable are complete separated from each other). Under the right work table is the band knife then reintroduced into the cutting portal. From the front are on the cutting portal to protect the operator doors appropriate.

Technically This cutting unit was designed to be on rails (Linear guide right) moves, under the right worktable to its respective end (front and rear) is driven. This allows the cutting portal in each case out of the right work table and in front to the end of the right work table and also back to the end to the other end of the work table.

there became the length (Depth) of this right work table, however, chosen larger than that of the left table. The dimensions of the right working table are 4000 mm (depth) × 2585 mm (Width). The work surface on this right table amounts to 2750 mm (working length) × 2385 mm (Working width). The left work table has a length (depth) of 3000 mm × 3000 mm (width). The work surface is left 2750 mm (working length) × 2800 mm (Working width). The work tables have a height of approx. 900 mm (adjustable). The working height is 1400 mm plus 100 mm reserve. The currently highest foaming height is at a maximum of 1240 mm.

Left and right side stop:

By this construction is made possible that the cutting unit can be moved far enough to the rear (ie to the end of the longer, longer lasting Table), so that the entire working surface of the left and right Table is completely free. This in turn makes it possible for the first time each with a servo geared motor (clearance) driven side stops in any way over the entire working width of both worktables moved to the left and right can be just because the cutting unit with its open band knife no more hinders standing in the way. Both stops are guided on linear guides and racks along the work tables, so on the one hand ensured Remains that adhered to the right angle to the work desks and on the other hand as quiet as possible can be moved. Constructive was at the same time on the right and left stop an adjustment possibility provided such that by loosening a jig Anytime a readjustment is possible, although this is the case the construction of 12 mm thick steel girders on which anodized 3 mm thick aluminum sheets are attached, not necessary is held. The dimensions the attacks each amount to 1400 mm × 2700 mm, so commercially available foam blocks hereby transported to both sides, ie to the right and left can.

Around to clarify it again: by the differently chosen length (depth) the work tables as well as their complete separation from each other (by which can drive through the band knife) can be both work tables completely free, so that the stops any left and right over the entire width of the tables can be driven.

Constructively, the left side stop was built so that there is an independent element with the dimensions 2800 mm × 1400 mm integrated, which can be opened. In the middle at the bottom there is a locking / unlocking mechanism which allows this element to be opened upwards from the frame of the stop. By the simultaneous attachment of a gas cylinder each right and left above it is then possible without much effort that this inner part of the left side stop by 90 ° upwards opens out of the side stop. The result is that thereby the entire space between the stop below (surface of the work table) and the cross member of the side stop at the top (gap of 1320 mm × 2700 mm) is released and thus foam blocks of the commercial sizes (1100 mm to a maximum of 1240 mm ) can be driven away.

constructive For the first time, it is an absolutely free mobility / mobility the attacks guaranteed.

Turntable integrated in the left work table:

in the left work table (dimensions: 3000 mm × 2700 mm) is a turntable measuring 2200 mm × 2200 mm built-in. This measure was selected because the usual Short block length at 2000 mm to 2100 mm. This turntable is along the front attached left work table. It is also here around a massive steel structure, in which there is a sufficient number of cross struts are located. Planked the work tables are also with Aluminum sheets of the type described above. In the middle of the turntable is in square shape (dimensions 300 mm × 300 mm) incorporated a stamp pad. Through the middle leads one Bush. In turn, a lifting cylinder (stroke: 202.3 mm; F = 6800 N; V = 11-15 mm / s; Motor 24 VDC), which is also electrically powered becomes. This leaves also be designed pneumatically or hydraulically. This will allows that the turntable from its rest position in the left turntable after pushed out of the table at the top and then (20 mm lower edge over the left work table) can be rotated. The maximum lifting height is 160 mm, so that the turntable in the raised state now by any 90 ° can be rotated in both directions. The turntable became square selected so that when turning over the Diagonal as possible a lot of load is rotatable. The turning process itself can either per Hand or electric or be performed as before driven. Under the aforementioned socket are 4 guide pins, which are in the under Table holes engage as a holding device when an angle of 90 ° rotated is. If it is minimally more or less, then the turntable is through these guide studs led into the underlying bearing plate. If the tolerance is exceeded, let yourself the turntable because of the guide pins do not introduce so that when it retracts always ensures an angle of 90 ° is. To when you extend or retract the turntable in the resulting Gap between turntable and outer work table despite mounted warning signs and warning marks bruises the hands to avoid leaves the turntable can only operate when both hands are on the control panel and therefor certain snaps actuated and kept.

The Tables on the right and left are independent. Exist between the two no connections. For this reason, steel and steel were used for stability not related to aluminum. It is a massive steel-welded construction.

operation the new machine and associated advantages over the previous technique:

Loading:

The new machine is loaded with the foam block by the left Stop unlocked and this stop thereby automatically (by means of Gas pressure cylinder) open to the top becomes. This will (without turning the left stop to 90 ° and an associated separation of the work surface) possible, by stacker the foam block to transport to the beginning of the left work table. Without big ones Trouble is the Then move the block from the forklift to the left work table. is the foam block is exactly applied to the header right to start from a straight line and squareness of the cut material. The loading can alternatively also be done by the left Stop open before loading and then driven to the right. Through this unrestricted trafficability of the left stop over the work tables to the right will clear the entire table area, so that it can be loaded without any obstruction.

Of the The advantage is that in tight spaces in this way space can be loaded saving. It also serves to protect the machine, if an inexperienced Forklift driver does not dare or barely dares left when the stop is open to unload the clippings on the left table. Anyway, it will open this way the clippings are brought to the left table.

In addition, will This avoids a manual pushing of the block, so that the Operator with the band knife does not come into contact. A danger to the body and Life or things are thereby eliminated.

is the left stop has been moved to the right, he can now retrieved and closed. Is he left at the left, he can now be closed.

To its positioning on the left or right header can be so cut the adjoining foam block exactly at right angles.

Cutting process when using the turntable:

thereupon is through the left stop the foam block to the knife gap promoted. In addition, can the right stop can be added to the exactly straight guide. Now lets easily cut the first page of the block clean. After that drives the left stop continues to the right, possibly the right stop also continue to move to the right. Now it is the clippings on the right table.

Of the Advantage is: the first (right) side of the foam block is without any turning maneuvers the left stop and table or dangerous by hand transport exactly straight and cut off at right angles. After the foam block has been spent on the right table, the cutting unit drive back so that now the left outer side of the block can be cut.

Of the Another advantage is: also the second (left) side of the foam block is without any turning maneuver the left stop and table or dangerous by hand transportation as well exactly straight and right-angled cut off (trimmed). Alternatively, you can this left side also after execution of the cutting program cut as last part and because of its pollution (silicone oil, talc) be disposed of.

This shows the great advantage of this machine:
Due to the unlimited mobility of both stops to the left and right over the entire length of the tables (because the cutting portal can be moved out of the table), 4 intermediate steps have been saved when loading the work table and when trimming 2 sides of the foam block. Before loading, the left-hand stopper does not have to be moved to the right with the turntable, after which the path only becomes free for unloading the foam block on the table. In addition, this turning process is saved again when the block is on the work table and the left stop is retracted again in a new turning operation in preparation for the first cut pass (4 intermediate steps) and thus the "first side of the block" before trimmed is the left stop. Here, the foam block is transported without any obstacles to the left table and transported by left stop to the cutting tool.

Now can after cutting the soiled right side of the preset program (programmed) and can select the strips, slices etc are cut. That at the beginning or at the end of this cutting process remaining left part can then be disposed of.

hereupon is the sliced / pieces etc cut, then transported on the turntable block turned by 90 °, so now be cut "across" can. This allows z. B. forms such as sponges get cut.

After completion of the cutting processes there are 2 possibilities of unloading:
Either the left stop can be opened and moved over the block to the right and then closed again. With the closed side (outside) then the clippings can be transported to the left to the end of the table and there loaded on the forklift or side table. The same procedure would also be possible if the right stop is used for this discharge by moving to the left.

By this construction will thus become the 6 intermediate steps described above saved.

Of the right stop can be equipped as the left stop additionally. All the above also applies to correspondingly changed dimensions and for a mirror image reversed Arrangement of all elements.

In addition, there are the following advantages:
Since the operator is no longer tempted to climb onto the working table of this chosen design form (which the applicant prohibits when using his machine), but the turning process is done manually or fully automatically, this operation protects the machine operator from injury and possibly Serious bodily injury from contact with the running and standing band knife.

at the same time By this technique, the production speed is saved by saving of 6 intermediate steps increased significantly because of the time-consuming Repeated turning away the left work table with left stop omitted.

Further the machine operator is no effort in the usual Demanded form.

These Cutting machine is thus much safer by their construction and more efficient.

An embodiment of the invention will be described with reference to 1 - 7 explained.
