Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for positioning a press bar in a paper punching device of a Jacquard machine.

In recent years, in the production of pattern paper, the method has changed from the method in which workers discuss the design drawings and punch them, to the method in which the design drawings are read using an automatic reader such as a pattern analyzer, the design drawings are once punched on tape, and then the tape is used. Electrically and automatically operate the paper perforation machine,
A method of perforating pattern paper is used.

The present invention provides a paper punching machine suitable for such a method, and in particular, a paper punching machine that uses a solenoid to operate press bars arranged in parallel to punch a horizontal row of paper at the same time. This invention provides a method for positioning a press bar in a machine, and will be described below with reference to the drawings together with an apparatus for carrying out the method.

In FIG. 1, reference numeral 1 denotes a shaft fixed to the machine base and extending in a direction perpendicular to the plane of the drawing, and one end of a control plate P is supported on the shaft 1.

A groove 2 formed at one location on the upper side of the control plate P
The memory hand 3 is engaged with and hangs down, while a spring 4 is connected to the plate P and is locked to a fixed shaft 6 via a hook 5, so that the plate P is always rotated counterclockwise around the shaft 1. energized. Further, the plates P are provided in a number corresponding to the number of horizontal holes in the pattern paper at equal intervals in the direction of the axis 1, and a locking plate 7 is fixed to the upper edge of each plate P to be operated by a solenoid S corresponding to the plate. ing.

That is, FIG. 2 is a view of the plate P portion in FIG.
are lined up in an orderly manner at equal intervals by collars 8 between the plates, and the locking plates 7 fixed to the upper part of the plates are arranged in a staggered manner so as not to obstruct adjacent plates. Solenoids SI to Sn are arranged above the locking slope, and are arranged so that when the solenoid rod 9 is lowered, the rod presses the locking plate 7. Furthermore, in FIGS. 1 and 2, a reset shaft extends parallel to the axis 1, extends over the entire plate castle area, and is supported at both ends by the mysterious moving plates 11, 11.
1 and 11, it is possible to take the upper and lower layers directly from the reset shaft 1, and when the reset shaft 10 is lower, each control plate P is pressed against the reset shaft, and the lower layer is taken against the spring 4. , are reset all at once.

On the other hand, directly above the reset shaft 10, the control plates that are not pressed by the solenoid rod 9 move up simultaneously following the reset shaft 10' by the force of the spring 4, and come into contact with the lower surface of the reset shaft 10. In addition, each of the plates F' has a groove 2 opened at the upper edge of the plate for hanging the memory needle 3, and a memory needle 3 whose upper end is bent into a U-shape is locked in the groove 2. Normally, the memory needle 3 is locked to the bottom of the groove 2 by its own weight.

A hole 12 is formed in the middle part of the memory needle 3, and a press bar 13 is horizontally passed through the hole 12 and supported, and the press bar 13 assumes two positions according to the upper and lower positions of the memory needle 3, When the press bar 13 is in the lower layer, the rear end surface of the press bar is pressed against the press grid 14. When the press grid 14 fixed to the moving frame 15 moves to the left, the press bar 13 is pressed by the press grid 14. The punch 16 at the tip of the press bar is slid.

The movable frame 15 is a guide 17, 1 fixed to the machine base.
8, and is moved left and right by a drive device that will be described later.

A die 19 forms the same number of holes 20 as the punches 16 in the direction in which the punches 16 are lined up, and the pattern paper 21 on the die 19 is perforated by the left row of press bars corresponding to the lower layer of the memory needles 3.

Reference numerals 22 and 23 are guard wheels for intermittently transporting the pattern paper 21 at a predetermined pitch, and claws 24 are set up at equal intervals on the outer periphery of the wheel.
engages with the feeding hole of the patterned paper 21, and the patterned paper is accurately and intermittently transferred at predetermined intervals without slipping.

Note that 25 is a felt impregnated with lubricating oil and is fixed to the end face of the moving frame 15 during punching, and the frame 26
It lubricates the punch 16 and die 19 when moving back and forth.

FIG. 3 shows the drive mechanism of the reset shaft 10.

That is, a pin 29 is fixed to the upper end of the lever 28 which is movable in the direction of arrow A with the fixed shaft 27 as a fulcrum, and the U groove 31 of the lever 30 is engaged with the pin 29. A mysterious moving plate 11 having a reset shaft 10 at its end is fixed to a shaft 32 having one end fixed thereto. 33 is a locking plate fixed to the control plate P and abuts on the reset shaft 10.

Therefore, due to the periodic activation of the lever 28, the pin 29
The lever 30 is placed around the shaft 32 as a fulcrum via the shaft 32.
The puzzle plate 11 fixed to the shaft 32 moves mysteriously in the direction of arrow B, and the reset shaft 10 moves up and down. The solenoid box 34 housing the solenoid 8 shown in the first figure is formed by a side wall, a solenoid fixing surface 36, and an upper wall 37, and the solenoid fixing surface 36 has a solenoid S mounting hole 38 and a ventilation hole as shown in the fourth figure. 39 is bored, and the ventilation hole 39 is bored so as to be located in the gap formed by the three solenoids S, so that an air flow is generated upward along the cylindrical outer peripheral surface of the solenoid S. .

That is, as shown in the first figure, a plurality of closed openings 40 are formed on the upper surface of the solenoid box, a fan 41 is attached to the closed opening 401, and the fan 41 is actively rotated to create an upward air flow inside the solenoid box 34. It forms a cooling device that releases the heat generated by the operation of the solenoid S. When a large number of solenoids are disposed closely together in this way, the cooling device described above is effective in improving the life of the solenoid.
In addition, what is installed below the memory needle 3 is a pattern copying device 4.
This is a device for creating a pattern paper identical to the pattern paper already perforated in step 2, that is, the master card 43. During drilling operations using this device, the above-mentioned solenoid S and control plate P do not operate. That is, by manually rotating the switching rod 45 that extends into the control plate P and forming the plane part 44 and setting it with the arcuate part facing downward, all the plates PI to Pn are fixed in position at the lower layer and reset. The shaft 10 and solenoid S are in an unrelated state. That is, a cylinder 46 for intermittently transferring the master card 43 is supported by a shaft 47 so as to be rotated by a pitch rotation device (not shown), and a bearing 48 supporting the shaft 47 is slidably supported by a pair of vertical rods 49, and the cylinder 46 is rotated by a pitch rotation device (not shown). An eccentric cam 50 is a shaft support 5 at the bottom of the bearing 48! A lever 52 is fixed to the shaft 51. When drilling with such a copying device, the lever 52 is turned in the direction of arrow C to rotate the eccentric cam 50 by a certain angle.
The bearing 48 that contacts the cam surface is raised along the rod 49 and fixed at a position where the upper end surface contacts the lower surface of the card pressing plate 53.

At this time, the lower end of the memory needle 3 is inserted into the hole 54 of the pressing plate 53, and the copy punching operation is set. During the punching operation, the rod 49 is moved up and down by a device not shown, and the cylinder 46, pressing plate 53, guide 54, etc. are moved up and down as a unit, and the memory needle above the hole in the master guard 43 enters the hole in the card. The press bar 13 maintains the lower calendar without being displaced, and when the press grid 14 moves to the left, it is pressed and perforates the pattern paper 21.

On the other hand, the memory needle in the position other than the hole in the master card is pushed up by the rise of the cylinder 46, and the press bar 13 also becomes an upper layer and no hole is punched. In this way, a stamp paper identical to that of the master card 43 is created.

A normal paper perforation operation that also depends on the control plate P in the above-mentioned paper perforation machine will be explained.

In FIG. 1, during the operation of the paper punching machine, the IJ set shaft 10 continues to reciprocate between two upper and lower positions, and the reset shaft 10
The solenoid rod S moves forward and backward in synchronization with the movement of. That is, in FIGS. 1 and 5, when the reset shaft 10 moves from A to A in FIG.
Pn rotates clockwise around shaft 1 against spring 4 and is in the lower calendar position. At this time, solenoids SI to Sn are activated by the design reading memory device and designated solenoids S3 to Si are activated. is energized and the energized solenoid S3
, Si rods 9-3, 9-i protrude with a constant stroke and support the upper surfaces of the corresponding control plates P3, Pi.
Subsequently, when the reset shaft 10 reaches the upper layer in FIG. 5C, the plate P corresponding to the specified solenoids S3 and Si is
3, Pi is pressed by the rods 9-3 and 9-i and remains in the lower layer), and the plates other than the plates P3 and Pi follow the rise of the reset shaft 10 and are rotated by the spring 4 to the upper layer. , the press bar 13 is in this state according to the design drawing.
is set. Therefore, if the moving frame 15 is moved to the left when the reset wire 10 is directly above, the rear end of the press bar 13 passing through the memory needle 3 supported by the plate in the lower layer will be pressed against the press grid 14. The punch 16 at the tip of the press bar operates, and the pattern paper 21 is perforated.

That is, the solenoid rod 9 is made to protrude when the plate P is directly at the lower level, and when the plate P pivots to the upper layer, it comes into contact with the upper surface of the plate and acts only to prevent the plate from pivoting, thereby pushing the plate from the upper layer to the lower layer. It does not have any lowering effect.

Therefore, compared to the case where the solenoid rod protrudes while pushing down the plate, the solenoid rod does not do any mechanical work in the above method, so the voltage applied to the solenoid can be small and is sufficient to keep the rod stationary at the protruding position. Good voltage.

As described above, in the present invention, the upper part of the press bar that perforates the patterned paper. A control plate that controls the lower two positions is supported freely around one shaft as a fulcrum, and the plates are positioned directly at the bottom all at once against a spring, and a set shaft is provided so that it can move up and down across the entire plate. At the same time, a solenoid rod that holds the lower order of the plate is arranged in correspondence with each of the control plates, and when all the control plates are once pressed to the lower layer by the reset shaft, the solenoid corresponding to the drilling position is energized, and the solenoid rod After projecting, the reset shaft is positioned directly above, and the control plate facing the non-energized solenoid also pivots toward the upper position, and the control plate corresponding to the energized solenoid is blocked by the solenoid rod to maintain the lower position. Since the perforation and non-perforation positions of the press bar hanging from the control plate are controlled, when the solenoid rod is energized and protrudes, it does not do the job of pushing down the control plate, but prevents the control plate from pivoting. All you have to do is energize the solenoid with enough voltage to do so, which reduces power consumption, and also reduces the amount of heat generated by the solenoid, greatly extending the life of the solenoid.
This is particularly effective when a large number of solenoids are used, such as in a paper perforator.
