Description

DETAILED DESCRIPTION OF THE INVENTION The invention provides: - a jacquard-type system, especially for embroidery;
The present invention relates to a control device for use with a jacquard mechanism for a machine or textile machine and a punching device that allows the rapid production of jacquard cards or tapes.

Jacquard mechanisms have been in use for almost 200 years)
, the tkVkII number O bin 1'#- entered or entered into this mechanism enlarged hole has a finger-like protrusion and a plurality of rows of coded holes '4
A tape is provided in front of the card.

Since the tape is moved relative to the bins, those bins that correspond to holes in the tape remain in their initial positions, while the bins that do not correspond to holes are moved to their initial or rest positions; This causes the embroidery, sewing or weaving machine to operate according to the predetermined schedule embodied in the coded holes.

Since the motion between the bottle, tape, and 0 is relative, the bottle is
If you wish, you can move the field towards the tape.

After each stitch or movement is read, the Jacquard tape is moved vertically in small increments to align with the next row of holes to be read. How long is the length of the Jacquard tape roll? 4 feet, this length is required to be carried out by this machine! It is determined by the number of movements. For example, in an embroidery machine, the length of the jacquard tape is determined by the number of stitches.

Additionally, when starting up the Jacquard tape, four lengths of unperforated tape must be passed through the machine to be fed through the Jacquard mechanism. Also, at the end of the Jacquard tape there must be another length of unperforated tape in order to be able to properly pull the tape out of the machine.

The physical size of the Jacquard tape, the cost of storage, the cost of the tape before perforation, the time consumed for loading and untapping the tape (this is done every complete cycle of the machine).
Because the use of jacquard tape has many advantages, it is expensive and time-consuming. do.

Additionally, holes that are not accidentally drilled in the tape, or that are blocked by dust or other O-obstructing substances, can cause errors in the intended operation of the machine. Additionally, the lifespan of Jacquard tape is limited by the length of the tape, since the presence or absence of holes in the tape is detected by the bottle, and the quality of the tape deteriorates after a large number of operating cycles.

It is an object of this invention to provide an improved Jacquard system and a control device that does not require special tape and can operate an existing Jacquard mechanism, preferably using an electronic control device. Additionally, a perforation device for preparing and reproducing Jacquard tapes is provided to substantially reduce the cost of manufacturing such tapes.

According to one aspect of the invention DIIIIIIK, there is provided a control device for a Jacquard mechanism having a number of longitudinally operable bins, each said control device facing and aligned with a corresponding bin. a plurality of identical hole closures disposed and arranged, each said hole device being moved reciprocatingly relative to said bottle to pass said bottle therethrough, and a selection for opening and closing each of said hole devices; It is configured such that only the bin, which includes a device and passes through one of the multi-opening hole devices, remains inactivated. Alternatively, the selection device may take the form of a rotating drum having a plurality of holes.

According to another aspect of the invention, a punching device for punching holes in a Jacquard card or tape is disclosed, the device comprising: a rotary drum having a plurality of holes; a plurality of punch fingers; a device for reciprocating the fingers relative to the drum as unperforated Jacquard tape is passed therethrough, the fingers penetrating the tape through correspondingly located apertures in the drum; Make a reciprocating motion to avoid this. Preferably, the punching device includes a printing device for printing instructions or instructions corresponding to the punched holes on the tape. Additionally or alternatively, a reader can be provided which simulates the round hole being drilled to verify the correctness of one hole.

The invention will now be explained with reference to Figure Ii.

1 and 2, a conventional jacquard mechanism has two rolls 2. Tape of length 1
including. The tape 1 is transported longitudinally by a sprocket wheel 4 or other suitable tape transport device.

The tape 1 passes through a feeding device 5, and the corpse feeding device 5 has a plurality of
The feeding fingers 9 can be reciprocated toward the bottle 6,
When activated, these bottles operate actual embroidery machines, carpet-making machines, weaving machines, etc.

As the tape moves into the bins 6, the bins 6, which remain inactive, pass through the holes in the tape 1 and thus remain in their rest position. However, the bins 6 which do not align with the corresponding holes in the tape 10 are actuated by the tape 1 and are moved from their rest position.

Thus, the presence or absence of each hole row O running across the tape 1 determines which bin 1 is actuated, and the order of the rows determines the order in which the bins 6 are actuated.

5-6, in accordance with a preferred embodiment of Jin's invention, the jacquard tape is replaced by a guide block 10, the cough guide block having a plurality of internal holes extending directly through the guide block. It has an orifice 11. Each orifice 11 corresponds to one bin 60 that remains unchanged. Guide block 10 is mounted on bracket 12 for reciprocating movement relative to the bin by a conventional operating mechanism of the machine.

A plurality of solenoids 13 are mounted above and below guide block 100, each solenoid having an armature 14 biased by a spring 15 to close orifice 11 when solenoid coil 16 is deenergized.

In FIG. 5, the solenoid coil 14i; is deenergized, thus blocking or closing the armature 14 orifice 11;
This actuates the bin 6 when the guide block 10 is moved towards it. However, as shown in FIG. 6, when the solenoid coil is energized, the armature 14Fi
is drawn towards the solenoid 13 against the action of the spring 150, thereby unblocking or opening the orifice 11 and allowing the bottle 6 to pass through the orifice 11;
This brings the guide block 10 into its rest position 11 when it is moved towards the bin 6. As can be seen from FIG. 4, locating the solenoid 13 both above and below the guide block 100 means that the adjacent solenoid 13
The 0 spacing can be made 02 times the spacing between adjacent bins 6 and their corresponding orifices 11.

A second embodiment of the control device according to the present invention is shown in FIGS.
Shown in Figure 0. A hollow drum 20 is attached to a frame 21 and its longitudinal axis @
It can be rotated in many ways. A guide rod 25 having a plurality of ports 24, each corresponding to one O bin 6, is disposed between the bins 6, the drum 20, and the O bins. Frame 21 #i Since the entire device is configured to be able to reciprocate toward and away from the bin 6, the bin 6 is attached to the guide rod 25.
t) through opening 24;

As shown in FIGS. 9 and 10, depending on the position of the drum 20, either the bins 6 are not moved from their resting position through the drum 20, or the bins 6 are not moved from their resting position through the drum 20.
are moved from their resting position without penetrating.

If any bins are to be moved from their rest position, it is determined by the position of the holes 25 in the drum 200, and in the particular case by the position of the drum. The desired program or sequence of operations carried out by the fingers 6 is a function of both the position of the holes 25 in the drum 20 and the position of the drum 20 determined by the stepper motor 22.

Those skilled in the art will appreciate that the solenoid armature 14 of FIGS. 93-6 and the drum 20 of FIGS. 7-10
Both II'i and II'i are strong and strong parts with a low rate of inertia. This results in faster operation of the control device and no wear as would occur with ordinary paper, jacquard cards or tape. Moreover, since the solenoid 1s or the stepping motor 22 is operated electronically,
The desired instruction program can be stored on magnetic tape or electronic storage media.

The drums 20 in FIGS. 7 to 10 are the irises 11 to 14.
The perforation machine shown in the figure can be used to make ordinary jacquard tape. Drum 20 is mounted to frame 30 and rotated by stepper motor 22 as previously described. Jacquard tape 1 passes through the punch head and card feed block S1, which reciprocates vertically towards and away from drum 20, raising and lowering the tape together with block 31.

A plurality of punch fingers 52 are housed within the block 31 and these fingers intersect with the bin 6 of FIGS. 1-10. The punch fingers 32 are biased by the spring 35 in a direction away from the tape 1.

Depending on the position of the drum 20, as shown in FIGS. 13 and 14, when the block 51 moves towards the drum 20, the punch fingers 32 will enter the drum 20 (in this case the tape will not be perforated). , or pressed downward by the drum 20 to compress the spring 33 and force a hole in the tape 1 as shown in FIG.

As will be apparent to those skilled in the art, the apparatus of FIGS. 11-14 can be used to control a stepper motor 22 using a program stored on magnetic tape.
Accordingly, the same program as the hole pattern of the jacquard tape 1 is created.

Additionally, these perforators can perforate at relatively higher speeds than conventional purely mechanical, tape duplicating and perforating devices. In addition, the punch fingers 52d (paper or cardboard) are M
Allows the use of relatively strong and durable materials such as YLAR® plastic films.

As can be seen from Figure 12, the drum 20Fi can also be provided as a plurality of coaxially arranged drum cylinders 20m, 20m and 200 as shown by the broken lines. This is particularly advantageous when the length of each drum 20m, 20B and 200 corresponds to a large number of holes 25 for receiving a single piece of data, such as a symbol or individual embroidery. Therefore, the drum is 20 m.

2011 and 200 are rotated independently from each other to form the hole 25.
A large number of combinations can be provided. Essentially, each drum 20m, 20II and 200 would require a corresponding stepper motor 22. In FIGS. 15 to 17, an equivalent device for the control device of FIGS. 7 to 10 is conventionally used to decode the encoded holes contained in each row. Tape "reading" implementation and advanced techniques are required.

Thus, in accordance with another embodiment of the invention, a tape printer and a perforator are combined and operated synchronously so that a blank tape is perforated with the desired coded holes and simultaneously or #1. At the same time, for example, explanations and instructions indicating the various stages of the embroidery process to be carried out are printed.

Thus, as shown in FIGS. 15 and 16, punch 40 and printer 41 are arranged side by side in the figures to produce punched and printed tape 43 from blank tape 42. Figure $17 shows blank tape 42,
The final perforated and printed tape 45 and the perforated only intermediate tape 44 are shown. It will be apparent to those skilled in the art that the direction of tape movement can be reversed or that punch 40 and printer 4
1, it is possible to print first and then punch.

Additionally, referring to FIG. 18, it is highly desirable that the Jacquard tape be equipped with a device to ensure that the tape is properly perforated. This makes it possible to detect minor errors that are not readily apparent to the eye, for example if the product is embroidered but the embroidery loosens prematurely.

Such a device is shown in FIG. The device includes a first stage 50, an intermediate stage 51 and a final stage 52. The first stage 50 is a perforation mechanism or a printer], the intermediate stage 51 is a reading machine, and the perforation machine configuration is either a printer), and the final stage 52 is a reading machine or a printer.

Obviously, each stage is different, and it is necessary to have a reader, a printer, and a perforator all one downstream from the perforator. K like this, tape 1
can be punched, printed and verified in a single pass through the device. As is clear to those skilled in the art, an optical reader or a mechanical reader may be used. optical reading)
The machine is easily recognized by the LAID device which directs the light westward through the hole in the tape 1 which is detected by a phototube.

Although the foregoing description describes only some of the embodiments of this invention, it will be apparent to those skilled in the art that variations thereof may be practiced without departing from the scope of this invention.
