The present invention is intended to contribute to the improvement of the efficiency of cutting operation and labor costs and prevention of contamination of the fabric by measuring the fabric of the fabric as necessary length and then automatically cut it.

Conventionally, in order to process embroidery, dyeing, etc. on the fabric of the fabric, a primitive method of cutting the fabric with scissors by pulling the fabric wound on the tubular body on a separate hook and pulling it to a place marked with the required length by a human hand. Have been writing. Therefore, the efficiency of the cutting operation was lowered, and the length of the cut fabric was not fixed, and there was a drawback of asking the fabric because it had to be pulled by a human hand.

In view of the above-mentioned drawbacks, the inventors of the present invention set the number plate formed in the control circuit to a number equal to the length required for cutting, and detect the number of revolutions of the rollers as an electrical signal at the counter formed thereon. When the number and the predetermined number is matched to stop the rotation of the roller and at the same time to operate the cutting knife (Cutting Knife) to be automatically cut, as described in detail with reference to the present invention as follows. .

The present invention is the cutting device (B) and the length of the pressing action and the cutting blade of the length measuring device (A) and the push holder (push holder) to operate the counter (C ₁ ) by changing the rotation of the roller to an electrical signal It consists of a control circuit (F) which adjusts the measuring device (A) and the cutting device (B) to act alternately with each other, and a known shifter system (G) which acts to fold the original fabric thereon. .

Length measuring device (A) is a roller ( ₁ ) of the limit switch (LSW ₁ ) is provided with a mandrel of the cam (3) on one side of the roller (2) formed on the upper part of the base ( ₁ ) and connected to the counter (C ₁ ) R) is configured to be in contact with the main surface of the cam (3), the cutting device (B) is a body (6 ') of the double-sided cutting knife (6) to the rotating chain (5) installed in the fixed pressure holding holder (4) attached to the left or right able to be moved, and a body 6 'bottom bottom (6a) of the double-sided cutting knife (6) left and to the right and the center of the three limit switch (LSW ₂₎ (LSW ₃₎ (LSW ₄₎ 4'a of both sides of the blotter holder 4 'was swept away from the operation 7 (7') of the magnet MC (MC ').

The control circuit F comprises a counter C ₁ and its contact point C ₁ ′, magnets MC ₁ (MC ₂ ) (MC ₃ ) (MC ₄ ) and its contact point MC ₁ ′ (MC ₂ ″) ( MC ₂ ') (MC ₂ ") (MC ₃ ') (MC ₃ ") (MC ₄ ') (MC ₄ ") and limit switches LSW _1- (LSW ₄ ) contacts (LSW ₁ ') (LSW ₂ ') (LSW ₂ ") (LSW ₃ ') (LSW ₄ ') (LSW ₄ ") and the timer (T) is configured to interconnect.

The left and right flow apparatus G engages the gear 8 installed on one side of the roller 2 'and the gear 9 on which the crank rod 9a is bonded to each other so that the flow hole 10 moves forward and backward. It was. Reference numeral 11, which is not described in the drawing, is a case of the control circuit F, 12 is a fabric, and 13, 13 'is a fabric hanger.

Referring to the effects of the present invention configured as described above are as follows.

The number of lengths to cut the fabric is first set to the number plate Fa in the control circuit F, and then the switch SW ₁ is “on”. The pair of rollers 2 are driven by the motor M ₁ . The 2 'rotates with each other to discharge the fabric back. At this time, as the cam 3 installed on one side of the roller 2 rotates, the edge of the cam 3 presses the limit switch LSW ₁ , and this signal causes the number plate Ca of the counter C ₁ one by one. It works.

If the number of the dial (Fa) and the number (Ca) of the counter (C ₁ ) are identical, the motor (M ₁ ) of the roller (2) is stopped and the blotter holder (4). ') Moves forward and presses the fabric so that it does not move. At this time, the cutting knife 6 moves and cuts. This process is described in detail with reference to the control circuit (F). _{When 1} ) is turned “on”, power is applied to the magnet MC ₁ and the contact point MC ₁ ′ is attached to drive the motor M ₁ of the roller 2.

Thus while still work when the number (Ca) of a number (Fa) and a counter (C ₁₎ of the set value matches the power supply of the counter (C ₁₎ A contacts (C ₁ ') is falling at the same time the magnet (MC ₁₎ of the The rotation of the roller 2 is stopped because the motor M ₁ is stopped and stopped. At the same time, the “B” contact (MC ₂ ”) of the magnet (MC ₁ ) is“ on ”so that the power is supplied to the magnet (MC ₂ ), and the“ A ”contact (MC ₂ ′) is attached to the magnet (MC) (MC). ') Is activated so that the pressure holding holder 4' is moved forward as shown by the dotted line in FIG. 4 to press the distal end 12. At this time, the other contact point MC ₂ "is also attached to the limit switch LSW ₄ . The magnet MC ₄ is operated via the B contact LSW ₄ ″.

{When the contact A (LSW ₂ ') of the limit switch LSW ₂ is operated in the "ON" state, the contact B (LSW ₂ ") becomes" OFF "and the contact B of the limit switch LSW ₄ (LSW ₄ ") becomes" on ". On the contrary, when the contact point (LSW ') of the limit switch (LSW ₄ ) is operated in the "on" state, the contact point (LSW ₄ ) of the limit switch (LSW ₂ ) is turned "OFF" and the contact point (LSW) of the limit switch (LSW ₂ ). ₂ ') is turned on.}

Therefore, the contact point MC ₄ ′ is attached to drive the motor M _{2 of} the cutting knife 6 so that the cutting knife 6 moves from left to right to cut the fabric.

Here, the cutting knife 6 is moved to the left side, and the bottom portion 9a of the cutting knife body 6 'presses the upper portion of the limit switch LSW ₃ installed at an intermediate point, thereby causing the number Ca of the counter C ₁ . ) Is returned to the zero point and moved.

At this time, the point A (C ₁ ') of the counter (C ₁ ) is turned on again.

When the cutting knife 6 is moved to the right end, the bottom portion 6a of the body 6 'presses the upper part of the remote switch LSW ₄ so that the B contact LSW ₄ "is" OFF ". Since the power supply of the magnet (MC ₄ ) is stopped, the contact A (MC ₄ ′) drops and the motor M ₂ circuit of the cutting knife 6 is turned “OFF” to stop the cutting operation. Both magnets MC 'MC' of the holder 4 'are also supplied with power and stopped again.

At this time, contact A (MC ₄ ′) of magnet (MC ₄ ) is “OFF”, so contact B (MC ₄ ”) is“ on ”and connects circuit of magnet (MC ₃ ). LSW ₄ ) A contact (LSW ₄ ′) of “WON” is turned on and power is supplied to magnet (MC ₁ ), so contact (MC ₁ ′) is reattached so that motor (M ₁ ) for rotating roller (2) When the length measurement of the fabric 12 is repeated in the above-described process by driving, when the number Fa of the set length and the measurement length Ca coincide with each other, the cutting knife 6 is cut by the moving action.

The cutting knife (6) is a magnet (MC _3), the contact knife 6 is cut because the Motor (M ₂₎ by the "on" of the (MC ₃ ') is again driven in the opposite direction is moved from the right to left direction While cutting.

Left and right flow device (G) of the present invention flows to the left and right by the rotation of one gear 8 of the roller (2 '), so that the fabric 12 is discharged backward after the length measurement is the flow port of the upper and lower The fabric 12 is folded and folded in an orderly manner as shown by the dotted line in FIG. The timer T in the control circuit F is momentarily operated because the timer T is connected to the magnet MC ₃ when the cutting knife 6 is stopped at an intermediate position due to a momentary power failure or failure. When the power is supplied again when the power is supplied again, the power is supplied to the magnet MC ₄ first, and the contact point MC ₄ ′ is turned on to drive the motor M ₂ . By allowing (6) to proceed again, it is possible to prevent the short-circuit state of each other during power supply.

The present invention has an effect that can contribute to the improvement of efficiency and labor costs of the cutting work by measuring the length of the fabric so as to automatically cut the required length.
