Description

The invention relates to a keyboard jacquard card hitting machine for beating jacquard cards across rows for multi-colored fabrics, in particular Carpets, with a facility to facilitate reading and simultaneous Hitting all the colors of the cartridge, at which when reading the cartridge dots a the keyboard key assigned to the same color is pressed, that of a key group belongs to which one of the number of colors to be read from immediately includes adjacent buttons.

The known card punching machines for the production of jacquard carp without a device to facilitate the simultaneous reading and striking of all colors of the cartridge are usually equipped with a sixteen-key keyboard, each key having a punch. is assigned, which is to be brought into working position when the button is pressed. After all of the punches required for a punch have been brought into the working position, a hammer mechanism is actuated by means of which the punches in the working position punch corresponding holes in the jacquard cards. After the beat has taken place, the jacquard card is moved a little further for the next beat, and the above-described process then takes place again. When hitting jacquard cards for the production of multicolored goods, in particular carpets, the procedure in these machines is such that all colors are whipped directly onto a card without pre-cards. Each color is assigned as many punches as corresponds to the relation “total number of punches to number of colors”. This means that when striking a five-color product on a sixteen- key card-striking machine for each color, according to the relationship 16: 5 = 3, remainder 1, three punches and thus three keys are available. The sixteenth punch is left unused. For a four-color product, there would be four punch punches, for a three-color product, five stamps, etc. For a four-color product, the sixteenth stamp would of course also be used, since 16 is divisible by 4.

The following refers to a five-color commodity. But it is true analogous also for two-, three-, four-colored goods etc. For hitting a five-colored one As mentioned, there are three punches available for each color. For one blow can therefore only ever be brought into the working position by three punches will. After punching with these three punches, the card must be for the next stroke to be advanced by a corresponding piece. Are now for example the color I the buttons 1, 2, 3, the color II the buttons 4, 5, 6, the color III the Keys 7, 8, 9, the color IV the keys 10, 11, 12 and the color V the keys 13, 14, 15 and appear on the one containing the five-color carpet pattern Cartridges for one blow in a row are always the same colors, so they are all Press the keys associated with that color. However, it appears, for example, initially the color III, then the color II and then maybe the color IV so is for that Color III the corresponding first key 7, for color II the corresponding second key 5 and press the third button 12 for color IV. So it’s when beating not only to make sure that the correct color is struck, but also still that within the key group belonging to a color according to the In order of the colors on the cartridge the correct button is pressed. That requires a very high level of concentration, since you feel very comfortable with the sixteen keys available can easily deviate. The use of trained assistants is practically impossible.

To facilitate the complicated reading process described above and striking operation using a sixteen key machine without A machine of the type mentioned at the beginning has already been created (German utility model 1786 400). The same points in place of the known Keyboard with the keys in a row next to each other, in groups keys arranged one below the other, each group comprising a color. Included However, the disadvantage remains that all sixteen keys, i.e. for each color several buttons that need to be operated.

The invention is therefore based on the object of a card striking machine without creating this disadvantage of this known machine.

The solution to this problem is that a single, one of the Key group comprising the number of keys corresponding to the number of colors to be read to control all punch is provided that this group of buttons when successive reading of the cartridge points one after the other to appropriately large Punch groups by means of a switching device to control the key that is pressed is connectable within the punch group corresponding punch and that the circuits of the switching device each by pressing the buttons when Reading the successive cartridge points are triggered. As a whole just like that Many keys are to be actuated, how colors occur, the operator needs to concentrate only on reading one cartridge point at a time. This will make that flawless hitting of the jacquard card is much easier. Inexperienced operators can easily familiarize themselves and also work faster than before from the start.

Preferred further embodiments of the invention emerge from FIG the subclaims. An exemplary embodiment of the invention is given below described in the drawing. In this FIG. 1 to 3 a front view, a Top view and a side view of a machine according to the invention, FIG. 4 to 11 details of the mechanical part of the machine, various on an enlarged scale Views and Sections, F i g. 12 an electrical circuit diagram of the machine and F i g. 13 is a schematic diagram to illustrate the mode of operation of the subject matter of the invention.

The machine 1 according to the invention has an electrical control part, the essential parts of which are housed in the control cabinet 2 (FIG. 1), as well as a mechanical part, the details of which are shown in FIG. 4 to 11 shown in more detail and which will be discussed first below.

On a conventional machine frame 3 there is a carriage 4 with the one to be punched Jacquard cards. volume 5 (for example Verdol system) in the longitudinal direction. tion of the frame 3 arranged to be movable (Fig. 4,5) The jacquard card ribbon is mounted on a take-up reel 6 and a take-up reel 7 and runs on both sides a perforated table 8 rigidly connected to the frame 3 in controllable rollers 9 and 10, which are provided with the rollers in corresponding ones in the jacquard card band 5 Holes 11 engage.

Above the perforated table 8, a striking mechanism 12 is arranged, which over a linkage 13 can be moved up and down and is guided by four pins 14. In the In the bottom plate 15 of the striking mechanism 12, punches 16 are loosely inserted into corresponding guide holes hooked. With their tips, the punches 16 are rigid with the frame 3 connected and located above the perforated table 8 plate 17 out. Neither with the plate 12 lowered when the jacquard card tape is perforated, even in the raised state (FIGS. 4, 6), the punch 16 can be removed from this Slide out plate 17 so that they are always safely guided.

Each of the two parallel rows of eight punches 16 are assigned pressure strips 19 between the base plate 15 and the top plate 18 of the striking mechanism 12, a pressure strip 19 belonging to each punch 16. The pressure strips 19 are arranged displaceably in such a way that they can be brought either over the associated punch 16 (working position) or outside of them. The bars 19 are displaced by means of rods 20, 21, the rods 21 being actuated by magnets 22. In the working position, for example, in FIG. 6 the pressure bar 191y, while the pressure bar 191 is outside the working position. In Fig. 7 the same state of affairs can be recognized; here the working position for all pressure bars 19 of the right half and the non-working position for the left half are illustrated.

When the percussion mechanism 12 goes down, all of the punches 16 are initially lowered; However, while those punches over which there is no pressure bar 19 in the working position stop when they hit the Sacquard card tape 5 and move through the bottom plate 15 into the top plate 18 when the hammer mechanism 12 is further lowered, the remaining punches 16 are located in the working position Pressure strips 19 detected and punch a hole in the jacquard card tape 5. The control of the pressure strips 19 and the magnets 22 will be discussed in greater detail later when the circuit diagram is discussed.

The respective work cycle, the lowering of the striking mechanism 12, takes place after all of the pressure bars 19 to be actuated for the impact in question have been brought into the working position; With a five-choir product this is, according to the relationship 16: 5 = 3, remainder 1, three pressure bars 19, with a four-choir product four pressure bars 19, with a three-choir product five pressure bars 19, etc. the carriage 4 shifted a little so that the jacquard card tape 5 is released for a new beat. After a field of the tape - also referred to as a single card - is full in this way, the carriage 4 is moved back again and the rollers 9 and 10 are operated by hand so that the next single card can be punched. The actuation of the rollers 9 and 10 could of course also take place automatically. As already indicated, the striking mechanism 12 is actuated via the linkage 13. This linkage 13 is moved by an eccentric 23 which is driven by a motor 25 via a belt drive 24 (FIGS. 5 through 11). A coupling 26 is provided between the belt drive 24 and the eccentric 23 and is actuated by a controllable magnet 27 via a pawl 28. When the pawl 28 is raised, the clutch 26 is switched on. After exactly one rotation - the hammer mechanism 12 has moved downwards and upwards again - the pawl 28 engages again and in the process switches off the clutch 26.

From the eccentric 23 is next to the linkage 13 also at the same time another linkage 29 is actuated. The linkage 29 has the task of driving the carriage 4 after the jacquard card tape 5 has been perforated, one step further to be conveyed so that the next perforation can take place. The linkage 29 initially has a lever 29a, which sits rigidly on the shaft 30, which it shares with the linkage 13 and which is deflected when the eccentric 23 moves. This creates a Bumper 29 h set in motion, one end of which has a switch 31 able to operate, which switches off the magnets 22, whereby all are in the working position located pressure bars 19 are brought back into the out-of-work position. Furthermore, a further sub-linkage 29 c is actuated by the bumper 29b, which is connected to a rack 32 rigidly attached to the carriage 4 and thus to advance the carriage 4 by one step in accordance with the eccentric stroke able. It is necessary that the actuation of the linkage element 29c is regulated in this way is that the rack 32 is only set in motion when the hammer mechanism 12 moved up again. This can be easily done by making an appropriate setting of stop pieces 29d, in which the rod element 29c engages, reach. Further care must be taken that switch 31 is only actuated when the perforation is completed.

Overall, the workflow in the machine 1 can be summarized as follows be: 1. Engaging in working position all required for one stroke Pressure bars 19.

2. Loosen the pawl 28 and thus execute the blow the striking mechanism 12 via the rod 13.

3. After the blow has taken place when the striking mechanism 12 goes up, actuation the rack 32 via the linkage 29 and at the same time bring it out of work the pressure bar 19 via a switch 31 to be actuated by the bumper 29b.

Of these three steps, only the first is carried out partly manually by pressing the appropriate contact buttons, while all others can be controlled automatically. The manual operation is carried out in such a way that that for a multi-choir product, each choir only has one that can be operated mechanically by hand Key 33 is assigned to a keyboard attached to the machine frame 3.

According to the circuit diagram (FIG. 12), the electrical part of the machine is set up for a five-choir product. Of the sixteen magnets 221 to 22 ".j, three magnets are assigned to one of the buttons 31 , namely magnet 221 to 22, 11, button 33," Magnet 221v to 22.1, button 33, I, magnet 22v "to 221x, button 3311, etc.

The magnets 22 also include relays 34, which are just like the Magnets 22 in groups of three are each assigned to one of the keys 33.

A transformer 35, which can be connected to a power supply system and has a rectifier (not shown) connected upstream, serves as the power source. The minus phase of the power source first leads to the contacts 36 of the buttons 33. Depending on which of the contacts 36 is closed, the minus phase flows through one of the plugs 37 to the corresponding relay group 34. In the exemplary embodiment, for the sake of simplicity, only the wiring for the Button 33, shown; when the button 331 is pressed, the contact 361 closes so that the minus phase is applied to the relays 341 and 34111 via the plug 371.

-7- The plus phase of the power source is applied directly to all relays 34, so that when a corresponding key 33 is pressed, a circuit containing the associated relay group 34 is closed and the contacts 34 ″ of the relays are thus attracted when the button 331 is pressed, all contacts 34 ″ 1 to 34, 13 of the relay group 341 to 34111 are attracted. The plus phase of the power source is to be connected to the magnets 22 via the closed contacts 34 ″. However, although all contacts 34 ″ to 34, 3 are closed when the button 331 is pressed, for example, there is only one of these contacts Current flow to the corresponding magnet of the associated group of magnets 221 to 22111, which with. its minus phase lies directly on the power source, so that only this one magnet 22 is attracted and thus only a single pressure bar 19 is brought into the working position. The plus phase flowing via the contacts 34 ″ to the magnets 22 is controlled in the following way: The plus phase first leads from the power source to a switching band 38 and flows from here, depending on the position of the associated switching band contact 38 ″, via the lines a, b or c to one of the connector rows 39 to 39 (in the position shown, the plus phase leads via the line a to the connector row 39a). At connector row 39, the plus phase is branched in such a way that it is connected to contacts 34 "1, 34"4> 34 "7y 34.1. Etc. (in the drawing, for the sake of simplicity, only the connection to contact 34" is shown 1 and 34, 14 drawn). From the connector strip 39b, the positive phase flowing through the line b is distributed so that it is at the contacts 34 "" 34 "" etc., and in an analogous manner from the connector strip 39, such a division takes place that the over the line c flowing plus phase with the contacts 34 "", 34 ", etc. is connected.

When the button 33 is pressed, the position of the switching contact 38 ″ only a positive current through the contact 34a 1 to the magnet 221 flow and thereby attract it. One press of the button 3311 would accordingly, a current to the magnet 221v via the contact 34a4, that is to say likewise the first magnet of the second relay group 221v to 22v, flow and attract it. The same applies to all other keys. Each time it would be when printing on one of the buttons 33 in the shown position of the switching contact 38 ″ in each case the first magnet of the associated relay group will be attracted.

Simultaneously with the attraction of a magnet 22 is another of so-called self-holding contact actuated by the moving soft iron core 22 "of this magnet 40 switched on, which now causes the plus phase from the power source directly flows to these magnets 22 and not via the contacts 34 ″. This is from the following Reason required. When the pressed button 33 is released, it also releases immediately again the associated contact 34 "of the corresponding relay 34, 'so that the current flow is interrupted again via the contact 34 ″ to the magnet 22 which has just been actuated. However, the magnet 22 must remain attracted until all three hit one stroke required magnets 22 or pressure strips 19 brought into working position and the blow is carried out; only then are the magnets allowed to loosen again and thus be brought out of work. This happens as in the explanation of the mechanical part carried out by actuating the switch 31, whereby the The negative phase leading to the magnets is interrupted again.

When one of the buttons 33 is pressed down, a further contact 42 is closed with a slight delay compared to the closing of the contacts 36 via a lever 41. As a result, a coupling 38b of a motor (not shown) that is continuously running during operation of the system receives current, whereby the switching contact 38 ″ is moved a little further (in the drawing from line a to line b) When one of the buttons 33 is pressed down the second time, the second magnet of a relay group is attracted, i.e. magnet 2211 or 22v, etc. When the button is pressed the third time, the positive current flowing over the switching band 38 is routed via the line c, the contact 42 next to the clutch is actuated 381, at the same time the clutch 26, which sets the striking mechanism 12, as mentioned at the beginning, into action.

The machine is used as follows: Given is the one shown in FIG. 13 cartridge shown on the right of a five-color or five-choir product. The five intended colors white, green, yellow, blue and red are marked on the cartridge with the letters a, b, c, d, e, on the keyboard 33 and the corresponding three punched punches (marked with the circuit board in the drawing) I, 1I, 11I, IV and V are designated.

For the first blow, the colors green, green, red appear on the cartridge. These are beaten as follows: First, the key II of the keyboard 33 corresponding to the color green is pressed, whereby, as can be seen from the circuit diagram in FIG. 12 can be seen, the switch contact 38 'of the switching strip 38, which abuts the line a, the associated magnet 221V brings in the operating position. Subsequently, the key is pressed II again after the switching strip 38 with its switching contact 38 from the line a to the Line b is moved. This brings the magnet 22v, i.e. the second magnet of the magnet group 221v to 22v belonging to button II, into the working position the switching contact 38 ″ is applied to the line c. In this position of the switching band 38, the magnet 22xv is brought into the working position, i.e. the third magnet of the magnet group 22g111 to 22X1 .. belonging to this button.

The three holes for the first three cartridge points are now punched, as shown on the card in FIG. 13 is drawn in, and then the card is shifted a little under the striking mechanism 12 and can now be prepared for the second strike. At the same time, the next switching band contact 38a of the switching band 38 has reached line a. The colors red, white and white appear one after the other on the cartridge. Accordingly, the key V (red) must first be pressed so that the associated magnet 22g111 is actuated, i.e. the first of the magnet group 22g111 to 22g1- associated with key V. The color white now follows on the cartridge, so that key 1 must be pressed after switching strip contact 38 "has reached line b. This causes magnet 2211, i.e. the second magnet group 221 to 221 belonging to key I, to Since the color white now appears again on the cartridge, the button I is pressed again after the switching strip 38 with its contact 38 rests on the line c, so that the magnet 22111 is actuated switching strip 38 and corresponding other wiring or Umstöpselung the plug Pure 39 and 37, the subject invention allows the beating patterns of different color number switch If it is, for example, to a three-color pattern, so stood for each color according to the relationship 16:.. 3 = 5, remainder 1, five punches are available, then instead of the connector rows 39 ″ to 39, two further connector rows would have to be occupied. However, only three plugs would be required from each of these rows to branch the current. From the first row the relevant phase would have to be connected to contacts 34a 1, 34 .. and 34.1. are applied, from the second row of connectors to the contacts 34, =, 34a 7 and 34 ", l. ETC.

Furthermore, because five rows of plugs 39 are to be used, five lines a, b, c etc. would also have to be connected to them. Accordingly, the distance between the individual contacts 38, 1 would also have to be compared with the illustration in FIG. 12 can be enlarged, so that only after the switching strip 38 has been backed five times, a next contact 38 ″ comes to rest on a line connected to the connector row 39.

In the case of a three-core product, the plugs 37 would also have to be unplugged accordingly, since only three buttons 33 are required. The plugging would have to be done in such a way that the relay groups 341 to 34v on the switch 361 belonging to the button 331, the relay group 34v to 34g from the switch 3611 and the relay group 34g1 to 34gv from the switch 3611 are connected. If instead of a three-color product there is only a two-color product, corresponding re-plugging must take place again, since only two buttons 33 are required for a two-color product, but on the other hand eight lines a, b, c etc. and eight rows of plugs 39.
