Apparatus for inserting pens into sample drums

The invention relates to an apparatus for using tifting in desert drums e.g. for textile and knitting machines, which semi-automatically with the help of a head, stamp and actuating means pens according to a template pushes into pre-drilled holes in a sample drum placed on a movable slide.

It is a device of individual to patternwise setting, sliding in radial grooves of a pattern wheel M mounted selectors on circular knitting and circular knitting machines are known which operates such that a selector according to the pattern, either the pattern wheel continues to rotate when actuated by hand by one step, and a selector of the pattern wheel moved from its starting position to another position or just rotates the pattern wheel one step further.

Likewise, there is a device for inserting three edging of selectors in sample wheels with the help of completely automatic means known, which are actuated by a perforated belt, the individual selectors from magazines get to a push-in mechanism that works like a stamp. There are those filled with selectors Magazines arranged in such a way that the aligning and conveying of the selectors was carried out by vibration

The disadvantage of these devices is that they are used to set or insert selectors in Imster wheels Devices can also be used to insert pins into sample drums. Furthermore a device of this type which also works with fully automatic means is disproportionately complicated and prone to failure, which is disadvantageous and costly, especially for smaller businesses.

A recent pin insertion apparatus for sample drums of jacquard machines is through a button or lever mechanism characterized, which pushes a pattern pen into a pattern drum when a first key is pressed and after pushing in a pin a carriage carrying the sample drum automatically by a hole division in moved further in the axial direction and locked, while pressing a second key only moves the V / agens in the original direction by one hole division

1098U / 0333

however, it does not cause a pin to be pushed in. This apparatus thus only enables mechanical actuation of the carriage and the sample drum in the axial direction, while the rotary movement of the sample drum by one row of holes must be carried out by hand. In this apparatus, too, the pens are made from a vibratory storage container fed to a push-in mechanism, the pens initially being in an above a cough-peg bed Arranged magazine get out of which the parallel stacked coughing pens through her Own weight fall on the Uusterstift bed. From this the bottom sample pen is created by means of a keypad pushed into the hole in the pattern drum aligned with it and also turned the pattern drum moved a hole distance in the axial direction.

A newer device of this type consists of a spring-loaded feeder and spring-loaded pen holder, which with a spring-loaded needle actuated by a toothed segment " cooperate ^

The main disadvantages of these devices are that, although they are of a simple construction, they require insertion the pins in pre-drilled holes of the sample drum by no means complex. For example, 3. both the possibility a simple setting as well as the overview between template and IIur; -terlroninel, as well as dio absolute Independence of the juewe ~ -'un; Ts: .icchani:; wen from each other

Working position (Fig. 10), whereby the .penetrating of the pin 15 is finished in the pre-drilled hole 9 of the sample drum 8. Lifting the lever 20 removes it Arm 79b from the punch 88, which under the action of the compression spring 89 returns to the original position (FIG. 9) while at the same time the other arm 79a of the angle lever 79 lifts the feeder 81 into the upper position for inserting a new pin 15 into the horizontal arm 85 As soon as the groove 85 is without a pin 15 for any reason, the monitoring device interrupts the continuation malfunction in the following way:

The end wall 96 (Fig. 12) of the slide 95 is due to The pressure effect of the spring 97 constantly acts on the feeder 81. Once in the horizontal groove 85 of the Feeder 81 is a pin 15, the slide 95 can not penetrate into the space of the groove 85 because the Front wall 96 of the slide 95 on the outer circumference of the Pin 15 slides (Fig. 15). In the opposite case it penetrates the slide 95 enters the space of the empty groove 85 due to its incline 98 and the pressure effect of the spring 97 CFig. 14-) and prevents further movement of the feeder 81. The monitoring device only allows the feeder 81 to move back into its upper one Position.

"A rotary movement of the support shaft 4 (Fig. 7) by one row of holes and a longitudinal movement of the same support shaft by a hole pitch of two lying in a row of holes Holes 9 of the sample drum 8 (Pig. 2) are made with the aid of independent actuating means

Any of these movements can immediately after the proper pushing of a pin 15 into a hole 9 of the Sample drum 8 can be carried out in any sequence and combination ™, Φ

As soon as pressure is exerted on the button 18 (FIG. 7) of the double-armed lever 36 in the direction of the arrow S., the lever J6 and the hinged tab 39 are aligned against the pulling action of the spring 40. As a result, the one-armed lever 41 presses on the stop screw 44 of the plunger 45, the pawl 46 rotates the ratchet 50 in the direction of arrow S ₂ by such an angle that it § the distance between the projection 47 of the plunger 45 μ and the adjustable stop 48 allows. After the button 18 is released, the double-armed lever 36, the tab 39, the single-armed lever 41 and the plunger 45 return to the original starting position as a result of the action of both springs 40, 49, whereupon the described function can be repeated. The ratchet 50 remains in the through

the rotation set position, v / eil the roller 51 mounted on the lever 52 by the tension spring f> 4- against the Teeth of the ratchet 50 is pressed and thus its unauthorized partial rotation prevented.

The actuating means for the longitudinal advance works in the same way as the actuating means just described of the carriage 2, which is in the arrow directions S ^ and

Sr _{7 can} move (Fig. 8).

As soon as a pressure is exerted on the button 19 (FIG. 8) of the double-armed lever 55 in the direction of arrow S and the lever 55 assumes the dash-dotted position 55 ', the cable suspended in the lever 55 and guided in guide rollers 57> 58, 59 moves 56 pushes the plunger 60 against the pressure of the spring 62. As a result, the tooth 64 of the retaining plate 65 releases the spring-loaded pawl 61, which engages the toothing 66 of the ruler 67 and moves it in the direction of the arrow Sr. The .bange of the advance is at least so great that the tube 69 of the ruler 67 is removed from an incision 75 of the guide strip 73 ^by the width thereof. At this point, the tension spring 70 causes the longitudinal advance of the carriage 2 in the direction of the arrow S ^ by the height of an incision 75 in the guide bar 73. The height of the individual incisions 75 corresponds to the individual hole pitches in the Muyter-

drum 8 (Fig. 2) and the width of the individual incisions 75 of the feed length of the ruler 67 in the direction of the arrow Sc, so that its stone 69 is no more than one Bneite of the incision 75 is moved. After approval of the button 19, the plunger 60 with the pawl 61 ′ returns to the original position as a result of the action of the compression spring 62 Back position in which the tooth 64 of the retaining plate 65 engages the pawl 61 with the toothing 66 of the ruler 67 interrupts. At the same time, the double-armed lever 55 also returns to the original A Position back.

The longitudinal advance of the carriage 2 in the direction of the arrow Sr ₇ , d. i · against the pulling action of the spring 70 »takes place in that the handwheel 7 (FIG. 1) is shifted by hand in this arrow direction Sn. In this way, the engagement of the Steines'69 with the respective notch 75 of the guide bar 75 is interrupted and at the same time the leading edge of 74- g overall to abut against the stopper pin 68 ^. compulsions. This is pressed by the incline of the guide edge 74 in the direction of the arrow S ^, so that the ruler 67 is also moved in this direction.
