Definitions

• the invention relates to a cutting machine for cutting blocks of material to form blocks of sheets, comprising a knife horizontally cutting through a block which extends across the working width of the machine and is horizontally movable relative to the block.
• the invention relates to a cutting machine for cutting flexible material, in particular foam blocks.
• DE 200 22 390 U1 describes a foam cutting device in which a horizontal cutting machine and a vertical cutting contour cutting machine are arranged one behind the other in a production line. First, a block is divided into plates by a vertical knife, forming a plate stack. The plate stack is then fed to the contour cutting machine.
• the invention has for its object to provide a cutting machine for cutting blocks of material into plates to form plate stacks, can be made with a block of any desired number of plates and separated, wherein in a simple manner, the formed plate stack of the remaining block can be removed.
• the cutting machine according to the invention is defined by the patent claim 1. It is characterized in that behind the Horizontaischne ⁇ dvoriques a removal device is provided which has a height-adjustable removal conveyor, that the knife is controlled such that it after completion of a section through the block first out of the Block moves out, then reverses and retracts into the block and finally starts up and raises the plate stack of the block, and that the removal device has a Separierorgan that the raised Plattenstape! engages and leads to the pickup conveyor.
• a first variant of the method according to the invention is defined by the patent claim 8.
• the knife of the horizontal cutting machine serves to form an opener for the initial lifting of the edge of the plate stack from the remainder block, so that the separating element is inserted into the open joint between Plattenstape! and residual block can penetrate to transfer the Plattenstapei on the pickup conveyor.
• the vertical position of the knife is stored in the control device. The knife can remain in the vertical position in which it left the block, in order to penetrate into the joint in a subsequent return. The security is given that the joint is not missed by an incorrect knife height.
• the knife that has performed the horizontal cutting process is moved out of cutting height in the block and then moved back into the previously formed joint.
• a second variant of the erfi ⁇ dungswashen method is defined by the patent claim 11.
• a block is first separated from the block, which is transported as a whole to the lower conveyor belt, so that can be cut with a horizontal knife plates.
• the horizontal contour or the stack of plates is cut only after removal by the removal device, while the sub-block is on the conveyor belt.
• the invention is suitable for CNC-controlled automatic cutting machines that automatically perform the operations according to a program, whereby the user can input the required parameters into the control device beforehand, such as the size of the block to be divided and the thickness of the plates to be cut, and the plate count of a plate stack.
• the invention offers a high degree of flexibility for the user. In particular, it is possible to divide a block of material into a plurality of plate stacks, each of which undergoes a different processing.
• the invention is particularly suitable for combination machines, which consists of a Horizontalschneidemaschme and a contour cutting machine, which are arranged one behind the other.
• the two machines can be arranged directly adjacent to each other, so that their cutting cloths or work belts directly adjoin one another, but they can also be spaced apart from one another and connected to one another by intermediate conveyors. It is also possible to supply the plate stack removed from the removal device to a temporary storage and then to process it further. This further processing can also be done with the same cutting machine, which has made the cutting of the blocks in plates.
• the removal conveyor is vertically movable in the removal device and that a conveyor belt is provided, on which the removal conveyor deposits a removed stack of plates.
• This conveyor belt is located in a conveyor line, which also includes the conveyor belt of the further processing cutting device, so that the plate stack is supplied after its removal by the removal device of further processing. In a double-cutting machine, this can be done by applying the stack of plates to the delivery side of the conveyor belt of the vertical cutting machine, the conveyor belt then being transported backwards onto the stack of plates in the knife area.
• Fig. 1 The general structure of a combined cutting machine
• FIG. 2 shows the same device as FIG. 1, but equipped with the removal device according to the invention
• Fig. 3 is an illustration of the removal device, as a separate
• Delivery device is formed and
• Fig. 4 is a schematic sequence of operations for lifting a
• a CNO controlled cutting machine 10 for foam blocks and other soft elastic material.
• the Cutting machine 10 has a base 11, the conveyor belts 12, 13 carries, which each form a work table for the material blocks to be processed.
• the conveyor belts 12, 13 extend over the entire working width of the machine. You do not have to form a closed work surface, but can also consist of several juxtaposed individual bands.
• the conveyor belts 12, 13 are driven in a controlled manner, so that the material block can be moved back and forth.
• a cutting frame 15 On a stand 14 of two fixed on both sides of the conveyor belt 12 posts a cutting frame 15 is fixed, which is controlled in height movable.
• the cutting frame is part of a horizontal cutting machine 16. It has a horizontal knife 17, which here consists of a band knife, but also a cutting wire would be possible.
• the knife 17 is rotatably controlled about its longitudinal axis, which forms the transverse axis of the horizontal cutting machine 16, so that the cutting edge can be selectively directed forward or backward.
• a vertical cutting contour cutting machine 20 is arranged in the transport path behind the horizontal cutting machine 16.
• This has a fixed annular frame 21 which guides a knife 22 arranged vertically.
• the knife 22 is a band knife or wire knife, which is moved in the longitudinal direction of its extension.
• the knife 22 may for example form a closed loop and be driven in rotation.
• the knife 22 is rotatable controlled about its longitudinal axis.
• the contour cutting machine 20 is a vertical cutting machine with which contour patterns can be cut into a block or a stack of plates.
• Figure 1 further shows a control panel 25, where the user can enter the desired parameters, and a control cabinet 26, a control computer contains all the operations of the two cutting device controls and coordinated with each other.
• FIG. 2 shows the same cutting machine as Figure 1, but additionally equipped with a take-off device 30.
• the take-off device 30, which is shown separately in Figure 3, has a frame 31 which stands on the ground and can be added to the cutting machine if necessary.
• the frame 31 carries a removal conveyor 32 from a circulating conveyor belt, which may also be divided into a plurality of parallel belt areas.
• the conveyor belt scraps around front and rear rollers, the rear roller being driven by a motor 33.
• the removal conveyor 32 is arranged rising from its front end to the rear.
• the removal conveyor 32 has a frame 35, on which the separating element 34 is attached.
• the frame 35 is linearly movable relative to the frame 31 in a guide 36.
