Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a selvage cutting device for a side trimmer used to collect band-shaped cutting waste, ie, stubble, generated during side trimming of foils and thin strips.

Conventional foils and thin strips (hereinafter simply referred to as strips).

) The band-shaped cutting waste generated during side trimming is divided longitudinally by the operator or with a razor, etc., and sucked into the suction duct, but such work requires considerable skill and is dangerous. There was a strong demand for labor-saving molds.

The present invention was developed in response to such demands, and includes a full-stage frame that can be raised and lowered at the side end of the strip conveyance line and movable in the width direction of the strip, and a strip with a notch cut into the measuring end using a side trimmer. The suction port of the ear suction duct and the cutter knife 4 for cutting the edge of the strip, which are fixed to the frame so as to be sandwiched in the vertical direction, are opposed to each other, and the cutter knife 4 for cutting the edge of the strip is placed in the direction of the suction port. a lifting device for moving the selvedge cutter knife in the width direction of the selvage, a positioning device for moving the selvage cutter knife in the width direction of the selvage, and a positioning device for moving the selvage cutter knife in the width direction of the selvage; All features are attached to the frame.

Embodiment 4 of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an embodiment of the present invention, in which 1 is a strip, 2 is a rotary blade that cuts into the measuring end of the strip 1 and generates cutting chips 3 in the form of a band;
4 is a roll provided in the circumferential direction of groove 2 into which the rotary blade 2 is inserted, and a shaft 6 extending in the machine direction of the strip 1 is slidably passed through a frame 5 that fully supports the rotary blade 2.

The frame 5 is equipped with bolts 7 that are fixed in position, and the shaft 6
A bar 8 slidably inserted into the frame 5 parallel to the
The frame 5 can be fixed at an appropriate position on the shaft 6 by bringing the tip of the bolt 7 into full pressure contact with the shaft 6.

The shaft 6 is supported by a cylinder device 9 so as to be movable up and down.

The swarf suction duct 10 is supported by the frame 5 so as to face the suction port 11 above the selvage of the strip conveyance line P where the strip 1, which has been completely cut into a predetermined cut by the rotary blade 2, is conveyed. There is.

and s) In order to support the cutting scraps 3 at the end of the IJ knob below the suction port 11 so as to be able to move freely in the entire vertical direction and in the width direction of the selvage of the strip 1, Holder 1 of cutter knife 12
3. A guide member 14 that supports the entire vertical movement, a cylinder device 15 that gives a vertical movement 4 to the slit knife 12, and a fully movable base 16 attached to the holder 13, and a strip 10 in the width direction. A rod 1T is slidably inserted into the frame 5 with its axis extending in the same direction as
A cylinder device 18 is attached to the movable base 16' at the rod end of the movable base 16, and a cylinder device 18 for moving the entire strip of the movable base 16 in the direction of the inside of the strip is attached to the fixed base 19.

In the above configuration, to adjust the position of the rotary blade 2, the cylinder device 94 is shortened, the frame 5 is pulled up at position 1 shown by metal a, the entire frame 5 is moved along the shaft 6, and the rotary blade 2 is moved to position 7 at an appropriate position. Tightening is stroked by actuation.

The rotary blade 2, which has fully adjusted its position, is lowered by the extension operation of the cylinder device 9, and cuts 4 are continuously generated in the form of band-shaped chips 3 at the side end of the strip 1 moving in the direction of arrow a.

In this case, the cut is made after the tip of the strip 1 has completely passed through the rotary blade 2.

Therefore, at this stage, the cutting waste 3 moves together with the strip 1 onto the strip conveying line P.

On the other hand, the cylinder devices 15 and 113 are kept in an extended state when the entire frame 5 is put on standby at the position shown in A above.

Therefore, when the frame 5 is lowered, the selvedge cutter knife 12 passes over the side edge 4 of the cutting waste 3, and the tip of the selvedge cutter knife 12 is positioned obliquely below the cutting waste 3.

Here, the cylinder device 18 is shortened and the selvage cutter knife 12 is guided directly below the cutting waste 3 (the state shown in Fig. 2), and the cylinder device 15 is fully shortened and the selvedge cutter knife 12 is shown with a 12-piece mouth. When it is raised to the position, the cutting waste 3 is transferred in the longitudinal direction (transfer direction of the IJ knob) in the process.
The tip of the cutting waste 3a on the rear side is sucked into the suction duct 10 from the suction port 11, and all the cutting waste generated thereafter rises completely within the suction duct 10 and is collected.

Since the present invention has the above-mentioned configuration, it is possible to automate the work of cutting and collecting cutting debris generated during side trimming, and it is highly effective in improving the work efficiency and safety of such work. .
