Description

[Detailed description of the invention] The present invention relates to a jacquard card punching machine.

Conventionally, in the punching of Jacquard cards, the design drawn by the designer was transferred to the person in charge of the design, and here the pattern was transferred to the design paper like the eyes of the base, the structure was accurately marked, and the design paper was transferred to the design paper. It was punched into a jacquard card by a skilled engraver.

In recent years, a machine has been developed that detects a design drawing using a phototube or phototransistor CG8, etc., and automatically perforates it.

The present invention further provides a novel punching machine, and the apparatus of the present invention will be explained below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a control plate in which a memory needle 2 is engaged with a long groove 3 and is suspended; one end of the plate 1 is pivotally supported by a shaft 4 extending perpendicular to the plane of the paper, and the plate 1 is swingable around the shaft 4. be.

A large number of the plates 1 are provided in the direction of the axis 4, and the number corresponds to the number of horizontal holes drilled in the Jacquard card 5, and the upper edge of each plate 1 has a solenoid 6 corresponding to each play 1.
A locking plate 7 that is acted upon by the locking plate 7 is fixed to each plate, and the locking pieces 7 are arranged in a zigzag pattern in a direction perpendicular to the plane of the paper.

Furthermore, the plate 1 is connected to the lower end of the spring 8,
The upper end of the spring is locked to a hook 63 hooked to the horizontal rod 9 of the machine frame, so that the spring is always biased upward.

Instead of the hook 63, it is also possible to hang a chain and lock the spring to the chain.

The upper limit position of each plate 1 is determined by the stop plate 11 of each plate abutting against a reset shaft 10 extending in the direction of the axis 4 to the plate area.

Reference numeral 6 denotes a solenoid that presses the locking piece 7 of each plate 1, and is provided as many as the number of plates 1.
Control of the plate 1 is performed by retraction.

The ON finger ◇ of the solenoid 6 is turned on by a design number reading and storing device (not shown).

The solenoid box 65 that accommodates the solenoid 6 is formed by a side wall 66, a solenoid fixing surface 67, and a clay wall 68. The solenoid fixing surface 67 has a solenoid 6 mounting hole 69 and a ventilation hole 70 as shown in the third figure. The ventilation hole 70 is bored so as to be located in the gap formed by the three solenoids 6, so that an air flow is generated upward along the cylindrical outer peripheral surface of the solenoid 6.

Openings 81 are formed at multiple locations on the top surface of the solenoid box, and a fan 82 is attached to the openings 81. By actively rotating the fan, an upward air flow is generated within the solenoid box 65, and when the solenoid 6 is operated, It forms a cooling device that releases the generated heat.

When a large number of solenoids as described above are placed closely together,
Such a cooling device is effective for the life of the solenoid.

13 is a switching rod for Jacquard card copying, which has a flat part 14 formed in the axial direction;
is positioned facing downwards and is not related to the behavior of plate 1.

That is, the notch 16 of the cam plate 15 fixed to the end of the rod 13
Then, a roller 19 provided at one end of the lever 18 biased by the spring 17 is inserted to position the switching rod 13.

The rotation of the rod is rotated by hand during copy punching.

A notch 20 or 21 positions the copy punch position of the rod 13.

Therefore, when the roller 19 is inserted into the notch 20 or 21, the arc portion of the rod 13 is located downward, and at this time, all the plates 1 are positioned in the downward position and take a position independent of the solenoid 6.

A long groove 3 for hanging the memory needle 2 is formed in each plate 1 and opens at the upper edge of the plate 1, and the memory needle 2, whose upper end is bent into a U-shape, moves up and down in the long groove 3. The memory needle 2 is normally locked at the bottom of the long groove by its own weight.

In addition, a presser 23 is horizontally penetrated and supported by the hole 22 in the middle of the memory needle 2, and takes two positions according to the upper and lower positions of the memory needle 2, and when in the lower position, the presser 23 is in the operating position, Pushed by the press grid 25 fixed to the moving frame 24, the punch 26 at the tip of the press spar 23 is slid.

Numeral 64 is felt impregnated with lubricating oil and is fixed to the movable frame 24 over the width of the punch to lubricate the punch 26 and the guide when the frame moves back and forth.

The movable frame 25 is movable left and right on the guide 27.2B, and is slid by means described below.

A die 29 has the same number of holes 30 as the punches 26 in the direction in which the punches 26 are arranged, and the jacquard card 5 on the die is punched by the left row of the presser 23 corresponding to the lower position of the memory needle 2.

31 and 32 are card wheels that intermittently transport cards 5 at a predetermined pitch; pawls 33 set at equal intervals on the outer circumference of the wheel fit into the feeding holes of the cards 5, and the cards are accurately and intermittently transported without slipping. .

Furthermore, 34 is already punched jacquard card 35
This is a copying machine for punching the same card as the above-mentioned one, by rotating the aforementioned switching rod 13, all the plates 1 are lowered at once against the spring 8, and the lower end of the memory needle 2 is positioned at the position shown in Fig. 1. .

Further, a cylinder 3 for intermittently transferring the master card 35 is provided.
6 is rotatably supported by a pitch rotation device (not shown).
A bearing 38 supporting the shaft 37 is slidably fitted to a pair of vertical rods 39.

An eccentric cam 40 is supported by a shaft 41 at the lower part of the bearing 38, and a lever 42 is fixed to the shaft 41.

Further, 43 is an eccentric cam receiving member fixed to the vertical rod 39, and the member 43 follows the vertical movement of the rod 39 in the direction of arrow A.

Furthermore, a memory needle guide 45 having a small hole 44 and a card pressing plate 47 having a hole 46 are fixed to the upper part of the rod 39, and move up and down together with the rod 39.

The state shown in FIG. 1 shows a reset state in which the copying device 34 is not in use, and when operating the device, the lever 42 is rotated counterclockwise, and the eccentric cam 40 fixed to the shaft is rotated in the direction of arrow B. By rotating the bearing 38, the bearing 38 is raised along the rod 39 and fixed at a position where the upper end surface 48 abuts the lower surface of the card pressing plate 47.

At this time, a slight gap is provided between the pressing plate 47 and the cylinder 36, and the master card 35 passes through this gap.

When the cylinder is in the raised position, the copying device is set and the lower end of the memory needle 2 is also inserted into the hole 46 of the pressing plate 47.

In this state, the sliding rod 39 is moved up and down by a device not shown, and the cylinder 36, press plate 47, and guide 45 are moved up and down integrally.

At this time, the memory needle at the position where the hole is in the master card 35 enters the hole in the card, and without being displaced, the press bar 23 is in the state shown in FIG. The presser 23 moves to the left and punches the jacquard card 5 in the same manner as the card 35.

On the other hand, when the master card 35 does not have a hole, the memory needle is pushed up by the surface of the master card 35 by the same length as the rise of the cylinder 36, displacing the presser 23 upward, and no punching is performed.

In FIG. 2, the drive mechanism of the reset shaft 10 is shown.

That is, the lever 5 is swingable in the direction of arrow C about the shaft 49 as a fulcrum.
A bottle 51 is fixed to the 0 end, and a long groove 154 of a lever 53 fixed to a lever 52 is fitted into the bottle 51, and a reset button for pressing and releasing the locking plate 11 of the plate 1 is attached to the end of the lever 52. A shaft 10 extends across the entire plate in a direction perpendicular to the plane of the drawing.

The plate 1 is loosely fitted onto the shaft 4 and moves up and down in the direction of the arrow.

Therefore, as the swinging lever 50 swings, the lever 53 swings around the shaft 54 via the bin 51, and since the levers 52 and 53 are integrally fixed to the shaft 54, the lever 52 and the shaft 54 swing together. The reset shaft 10 moves up and down by swinging in the direction of arrow E about the center.

The movement of the reset shaft 10, the operation of the solenoid 6 and the movement of the moving frame 24 are interrelated, that is, when the reset shaft 10 is in the lower position, the plate 1 is lowered against the spring 8. At this time, the solenoid 6 is activated by the design reading/memory device, a specific solenoid is turned on, the rod 12 protrudes, and then the reset shaft 10 reaches the upper position, and at the same time the moving frame 24 moves to the left. ing.

When the reset shaft 10 is in the upper position, the plate 1 corresponding to the specific solenoid 6 remains in the lower position, and the other plates 1 are returned to the upper position by the spring 8, and the presser 23 is set according to the design drawing. As the moving frame moves to the left, a punch corresponding to a predetermined presser is actuated, and the jacquard card 5 is perforated.

Therefore, the rod 12 of the solenoid 6 does not act to push down the protruding plate when the plate 1 is in the lower position.

That is, it has the effect of a stopper. Reference numeral 55 in the second figure is a solenoid for punching the feed hole in the jacquard card 5, and a spring 5 is connected to the rod of the solenoid 55 via a connecting rod 56.
7 The biased lever 58 is supported by a shaft 59, and a support shaft 61 of a presser 60 is fixed to the lower end of the lever 58.

That is, normally when the solenoid 55 is not energized, the rod 6
2 is in the lower position, so the spring 57 causes the lever 58 to be in the upper position, and the presser 60 is in the double-dot vertical line position.

When the solenoid 55 is turned on during drilling, the rod 62 retreats, and the lever 58 descends against the spring 57 via the connecting rod 56 to assume the lower position, and the press spar 60 mounted on the shaft 61 also moves to the lower position, that is, the solid line. Once in position, it is pressed by the press grid on the movable frame side, and card feeding holes are bored at both ends or at the center of the Jacquard card.

The punching operation by the above device will be explained next.

First, a punching method using an automatic reading storage device will be described.

From the device that read and memorized a row of design drawings 1 9 1
7.25...1337th is read out,
A signal is input to the solenoid 6.

Prior to the signal, all the plates 1 are in the lowered position against the spring 8 due to the lowered position of the reset shaft 10,
At this time, the solenoid 6 is energized and the activation or deactivation of the solenoid 6 is selected according to the design drawing, and the rod 12 protrudes and descends from the solenoid with the on finger →, and the rod of the solenoid without the on finger → takes the upper position. Under this condition, when the reset shaft 10 is in the upper position, the plate 1 corresponding to the lowered rod is blocked by the rod and remains in the lower position, and the blenoid 1 for the de-energized solenoid is not blocked by the rod 12, so the spring 8 to rise to the original position.

When the moving frame 24 moves to the left under such a plate arrangement, the press spar 23 supported by the memory needle 2 of the lower plate is pressed against the press grid 25, and the jacquard card 5 is punched. Since the memory needle hung on the plate in the upper position is raised, the press spar 23 supported by the memory needle is not pressed against the press grid 25 when the frame 24 moves to the left, so no punching is performed.

In this way, design drawings 1, 9, 17, 25...
・The 1337th hole is punched in the first row of the jacquard card, followed by the design drawings 2, 10, 18, 26...1
If the 338th hole is punched in the second row in the same manner as above, and then 8 rows are punched in the same manner as above, the number for the first row (1, 2, 3...1344) of the design drawing will be punched. The perforation is completed as a jacquard - autumnal equinox.

Next, the second part of the design drawing and the first part are perforated in the same manner as above.

Next, a method of punching a copy card using a master card will be explained.

In the case of the copy punching operation, as described above, the solenoid 6 is not used, the plate 1 is maintained at the lower position, and the presser 23 is controlled by moving the memory needle 2 to the upper and lower positions using the master card 35. .

That is, the switching rod 13 is manually rotated clockwise or counterclockwise from the position shown in FIG. 8 and the plate 1 is fixed in the lower position.

Therefore, the memory needle 2 hanging down from the plate 1 is also in the lower position, and the press 23 supported by the memory needle 2 is set in the position pressed by the press grid 25, that is, in the lower position.

At this time, the lower end of the outer memory 2 is located within the hole 46 of the card pressing plate 47.

Furthermore, by turning the lever 42 in the direction of arrow F, the eccentric cam 40
rotate the cylinder 36 and the bearing 38 to the sliding rod 39
The upper surface 48 of the bearing 38 is raised along the card pressing plate 4.
7, and copy punching is completed.

Note that the master card 35 is wound around the cylinder 36 in advance before the cylinder 36 is raised.

When copy punching is prepared through the above operations, the drive source starts driving and punching is performed.

That is, when the sliding rod 39 rises every time the master card 35 is pitch-fed, and the cylinder 36 fixedly provided on the rod 39 via the eccentric cam 40 rises integrally with the card pressing plate 47 - the master card Memory needle 2 on 35 perforations
remains in the lower position, while the memory needle 2 on the non-perforated card is moved upward by the master card 35.
Position the presser 23 at the upper level.

In this state, the moving frame 24 moves to the left, the press spar 23 at the lower position is pressed by the press grid 25, and the jacquard card 5 is punched by the punch 26 at the tip of the press spar 23.

Since the plate 1 is fixed when the memory needle 2 is raised, the U-shaped upper end locking portion with memory operates to move upward along the long groove 3 of the plate 1.

When punching of a portion of the master card is completed, the movable frame 24 returns to its original position, and then the cylinder 36 and card pressing plate 47 also return to their original positions due to the lowering of the slot 39, and all the memory hands 2 are reset.

At this time, that is, when the cylinder descends, the cylinder 36 rotates one pitch by a pitch feed mechanism (not shown), and the second and third ends of the master card 35 are located directly below the memory.

The above operation is repeated, and punching of each row of master cards is performed one after another at the same time.

Next, a punching operation using both punching by the electromagnetic solenoid 6 and copy punching by the master card 35 will be described.

In other words, the pattern paper has a hole common to each pattern paper called a peep hole, an attached hole that functions as a boto, a folding machine, an ear, a shuttle change, a winding stop, etc., and which circulates through multiple pieces of the pattern paper, and a hole that is common to each pattern paper. There is a diaphragm hole that changes little by little as the pattern changes depending on the pattern.

Of the various holes mentioned above, the holes that are common to each patterned paper and the holes that circulate among a plurality of patterned papers are copy-punched using a master card, and only the aperture holes are punched by operating an electromagnetic solenoid.

As shown in Figure 4, the Master Card used for such punching is a window frame-shaped Master Card in which only the peephole and attached hole parts Q1 and Q2 exist as pattern paper, and the part P that originally had the aperture hole has been cut out. 35a is used.

Therefore, when punching is performed using the master card 35a and the electromagnetic solenoid 6 in combination, the master card 35a
a to the cylinder 36, and reset the reset shaft 13.
Alternatively, all the plates 1 are pushed down to the lower position by the bushing rod 10, and in this state, the Ql of the MasterCard shown in FIG.

All the electromagnetic solenoids corresponding to the Q2 area are turned on, and the binding rod 12 is fixed in the lower position.

Therefore, the electromagnetic solenoid corresponding to the P area of the master card 35a is controlled for each line of printing paper, and controls the plate 1 to be punched with the aperture hole.

In this way, by using the master card 35a for punching the peephole and attached holes and using the electromagnetic solenoid 6 only for punching the aperture hole, all the solenoids are not constantly used, and the life of the solenoid is extended. At the same time, the generation of heat can also be kept constant.

As described above, according to the present invention, a plate corresponding to a row of cards is provided so as to be swingable about a single axis, and the plate has the following features:
The memory needle supporting the press bar is suspended, and a solenoid corresponding to a card row is arranged corresponding to each plate, and the solenoid is operated according to a command from the design drawing reading storage device to determine the memory needle in two positions. Furthermore, the above-mentioned first position can be determined to be in the second position depending on whether or not there is a perforation in the lower master card with memory.

Therefore, the press bar supported by the memorized needle is also determined to be in two working and non-working positions, and in this state, by simultaneously operating the press grids that press the press bar in the working position, the press bar is arranged in a row on the jacquard. Punching is applied to each
It is capable of extremely high-speed punching.

Furthermore, the apparatus of the present invention can arrange a horizontal row of design drawings at any position in a row of jacquard cards, and can create jacquard cards with different layout patterns from the same design drawing.
