Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting device for cutting a roll-shaped material into one or several small pieces having a desired width, or for trimming the ends. The elongate cutting operation is performed in the space between the rotating annular cutting tool and the spacing tool. The material of the strip to be cut into an elongated shape is preferably steel, aluminum or plastic. The present invention relates to the rapid exchange of cutting and spacing tools on a mandrel of a cutting device for cutting in an elongated manner and to store them in a narrow place in communication with the cutting device.

[0002]

2. Description of the Prior Art Cutting a wide, roll-shaped material in a longitudinal direction is performed by cutting device means, that is, in an elongated cutter, two cutting rings arranged one above the other, namely an annular cutting device. It is suitably carried out between. The strips are assembled vertically one above the other and are handled between two horizontally extending mandrels provided with an annular cutting device and a spacing device. The spacing device is for obtaining an elongated cut piece having a desired width. The ends of the two mandrels are held by two bearings in the frame. The frame portions are often arranged on the same base.

For example, the desired strip width, and / or
Or when changing the thickness, change the material and
Depending on the wear condition of the cutting tool on the mandrel, the tool set is reassembled or a new one is assembled. Alternatively, how frequently the tool set should be changed is determined according to the work order. New elongated cutting tools have high productivity and cutting speeds are often 600 meters per minute or more. The performance of the elongated cutting device is highly dependent on the reassembly of the tool set and the time required for assembly. Reassembly and assembly of the tool set is currently performed in two different suitable ways. One way is a mandrel,
This is a method in which the entire frame portion including the cutting tool and the space holding tool is removed, moved to another location, and replaced with a new tool set. Often it is possible to change tools and directly replace the tool set of the elongated cutting device. Another method reassembles one of the frame sections in a well-known manner so that one of the mandrels is free, and reassembles and assembles the tool set with the mandrel in place. Such elongated cutting devices have been disclosed elsewhere in EP 044047 and EP 0784942.

[0004] The latter method is preferred by most users of the slender cutting device, but is said to be inexpensive. Many users also state that the method is faster if the tool set is changed in an advanced manner.

The easiest way to change tool sets is
In this method, the cutting tool and the spacer are loosened from the mandrel, the tools are disassembled one by one using a hand or a normal tool, and then assembled using a new cutting tool and the spacer.

[0006] Patent EP 0 784 942 discloses an assembling device which facilitates the exchange of the entire tool set. The assembling device is provided with a pair of upright, mutually disposed bars, similar to the mandrel of the cutting device. Preferably, the assembly apparatus is provided with at least four pairs of bars oriented in different directions. The assembling apparatus is provided so as to be movable between a mounting position and a connecting position in a work base. The mating rods of the assembly are connected to the mating mandrels. For that purpose, the end wall of the work pedestal is openable. The used tool set is extruded on a bar. A new bar of the assembly device connects with the end of the mandrel and pushes the newly assembled tool set onto the mandrel. Movement of the tool set between the bar and the mandrel is performed by an extruder on an assembly device or an elongated cutting pedestal, or both.

[0007] The cutting implement and the spacing retainer are stored in a location near the elongated cutting pedestal or, if a plurality of elongated cutting pedestals are used, the plurality of elongated cutting pedestals. The storage location is expandable. The best way to provide a gap between two cutting tools to obtain a strip of material that has been cut to the desired width is to use a combination of spacing tools of different thicknesses. For this reason, there are often prepared more than one hundred kinds of spacing members having different thicknesses. Also, it is necessary to store many different cutting tools. The movement between the tool storage place and the work table is most easily performed by hand, but a robot is often used as a device, for example. Since the cutting and spacing devices are often stored on a horizontal floor, the storage space is large. It should also be noted that each tool set is composed of about thirty parts, and the robot can move only one part at a time, so that the movement time is long.

[0008]

This embodiment is a modification of the present invention. Other variants are possible within the scope of the claims.

The robot 1 includes a pedestal 2 having an extension that enables the robot to operate throughout the storage location. The pedestal is
Each of the four corners of the storage location has a total of four straight solids, one each. The tops of the uprights 3 are connected by four horizontal bars 4 along four surfaces of the storage place. The carrier 5 can move back and forth in a horizontal plane on the two parallel horizontal bars 4. Carrier 5
Is driven by an electric motor via an infinite belt with gears. The belt is driven along one horizontal bar 4. The cross transport 7 travels across the longitudinal transport 5. This carrier 7 is also driven by an electric motor via a long screw. The vertical holding device 8 is mounted on the cross transport device 7. The vertical holder 8 is vertically movable in the vertical direction. At the lower end of the vertical holder 8, a robot tip 9 having a gripping device 10 protruding in the horizontal direction is mounted. Robot tip 9
Is movable in a plane crossing the vertical axis of the holder 8.

A storage unit 11 is provided within the radius of the robot tip 9 (see FIG. 3). Each storage unit 11 has an upright rectangular frame structure 12. On one side or both sides of the vertical surface of the frame structure 12, a large number of support fixtures protruding in the horizontal direction in the shape of a thick wall tube 13 are provided. The outer diameter of the tube 13 corresponds to the outer diameter of the horizontal mandrel of the cutting device means supplied from the storage location. A number of necessary annular cutting tools 14 and spacing tools 15 are housed on these tubes 13. The distance between adjacent tubes 13 should be at least such that the cutting tool 14 or spacing tool 15 does not rub against nearby tools as the tool moves along the jacket surface of the tube 13. . Each tube 1
An extruder 16 is connected to 3. The extruder is a tube 13
All the target tools stored above are transferred to the frame structure 12.

If the jacket 17 is full, the robot tip 9 places its load on the bar on which the tool set is assembled. The movement of the tool on the jacket 17 is preferably performed by the support 25 operating as an extruder.

The re-installation of the tool on the tube 13 in the storage location is performed in the reverse order. The support 25 is then used as an extruder, and the number of the tool unit attached to each tube 13 is determined by the travel length of the support 25 oriented to the tube 13.

[0019]

The effects of the present invention are clearly shown in the above embodiment. The robot 1 has a precise assembly of the storage unit 11 and a gripper 10 that handles many tools at the same time.
This significantly reduces the storage 11 and the distance between the storage 11 and the receiving device. The expansion of the storage space using the upper space makes it easier to provide the storage space 11 closer to the cutting device. It is possible to greatly reduce the travel distance.
