    As the carriage of a flatbed knitting machine traverses the needle bed, a pulse generator which comprises a toothed disc and two cycle signallers at its circumference produces pulses in synchronism with the carriage movement and corresponding to the needle cycle for electronic control of the machine. The toothed disc has a tooth pitch which corresponds in whole number multiples with the pitch of the needles in the bed. The pulse generator may be located on the machine frame or on the carriage. In the former case the carriage can have a pick-up which entrains a chain stretched on the machine frame with the toothed disc rotatable jointly with one of the sprocket wheels for the chain. In the latter case the toothed disc, carried by the carriage may be rotated by a coupled pinion which meshes with a rack stationary on the frame and co-extensive with the traverse of the carriage. In each case the pulse generator produces synchronized control pulses without direct scanning of the needles in the bed.

    The invention relates to a planar caulking machine comprising a forward and reverse x-locking carriage and a pulse sensor that has a pulse shaping disk and two clock sensors mounted around the perimeter of the disk, which is designed to move over a needle bed in a forward and reverse direction. for electronic control of a planar die machine.
    The purpose of the invention is to improve the quality and reliability of control.
    FIG. 1 schematically shows a carriage and carriage support assembly of a flat plate machine with a pulse sensor on the machine body and a pulse sensor drive through an endless chain set in motion by the carriage; in fig. 2 shows a pulse sensor on the carriage and a stationary toothed rack for driving the pulse sensor; in FIG. 3, a disk for forming pulses c. two clock sensors j, - top view; in fig. 4 shows a sequence of disk pulses, as well as a table for a sequence of clock pulses; in fig. 5 — a second disk for generating pulses; in fig. 6 - pulse sequence and sequence
    cycles for the second disk.
    The carriage 1 (Fig. 1) of the flat carriage passes along the guide 2 in the machine body and is installed on this guide through the support unit 3. The boxes of the yarn feeders 4 are connected through the bracket 5 to the carriage. Sprockets 6 and 7 are mounted on the machine body on its sides with the help of supports 8 and 9. These sprockets 6 and 7 move an infinite chain 10, which is additionally provided for the drive chain of the carriage ,, The sprocket 6 is firmly connected to the disk (not shown ) pulse shaping sensor 11. The sprocket wheel 7 is designed as a holding sprocket. With the aid of the engagement carriage 12 fixed on the bracket 5, the endless chain 10 is carried along by the carriage 1 between the leftmost position 13 and the rightmost position 14, the distance between which limit is rectilinearly -part tensioned chain. This rectilinear section of the circuit lies within the working range of the pulse sensor 11.
    The engagement 12 is firmly connected to the chain 10 within the chain portion between the leftmost position 13 and the rightmost position 14. Due to this, the sprocket 6 and the pulse shaping disc connected to it are driven synchronously with the movement of the carriage 1. The division along the perimeter of the pulse shaping disc multiple to needle division. In the case of dividing the needle in inches, the sprockets 6 and 7 have an inch division, and the endless chain 10 is an inch chain. The endless chain 10 can be made as an endless chain link, an endless ball chain, or an endless perforated belt.
    In the flat hinge machine (Fig. 2}, the pulse sensor 15 is located on the carriage 1 in the area of the bracket 5. A gear rail 16 is fixedly fixed on the car body, which extends at least within the detected working area of the pulse sensor 15. The pulse disk 15 of the pulses (not shown) through gear 17, which is engaged with the rack 16, is driven synchronously with the movement of the carriage 1. Instead of the rack, a gear rack can be used.
    The distance between the sprockets 6 and 7 (Fig. 1) is chosen so that the engagement 12 for driving the disc for forming pulses, at least in the working area, occurs on a straight line segment. In the forward and reverse movements of the carriage 1, the sprockets b and 7 perform left rotation, while they do not rotate when the carriage is reversed. A similar movement is made by the disk to form pulses.
    FIG. 3 shows a disk 18 for forming pulses with teeth 19. The division 19 along the perimeter of the disk 18 is equal to the division between the needles in the needle bed. Along the perimeter of the disk 18, two sensors A and B are displaced to each other by one quarter of the distance between the needles. The pulse forming disk 18 is fixed on the same shaft as a sprocket and, accordingly, gear 17, and, consequently, and synchronously with the movement of the carriage 1. is set in motion within the working area of the pulse sensor. This means that the disk is forming
    3
    the pulses are rotated by one tooth together with the gap between the teeth (division P of the pulse shaping disk) if the carriage is displaced by one division between the needles.
    FIG. 4 in the upper part shows the sequence of pulses of the clock sensors, A and E with the right and left stroke of the disk 18. The period of the pulses exactly corresponds to the needle stroke. The vertical median line corresponds to that shown in FIG. 3 position of the disk 18.
    The lower part (Fig. 4) shows logical coding for clock sensors A and B in conjunction with a pulse shaping disk 18 for right and left strokes. If the carriage moves further one needle cycle 11, the clock sensors A and B receive different switching states.
    FIG. Figure 5 shows an otherwise-produced pulse shaping claim 18 with teeth G9, which acts as a code sensor. The division P along the perimeter of this pulse shaping disc 18 is equal to the number of t divisions between the needles. Clock sensors a and b are located on the carrier plate around the perimeter of the disk 18 with displacement to each other by one division –t between the needles.
    The pulse sequence for clock sensors A and B is shown in FIG. 6 above for a disc 18 rotating in the directions of a double arrow. The period between pulses corresponds to four beats of the tit needle.

    FIG. Figure 6 below shows the lottery coding of clock sensors A and B. Only a certain logical combination for sensors A and B is taken per needle cycle. Therefore, the needle clock corresponds to one logical combination.
    The difference between the disks (Figs. 3 and 5). The formation of pulses, respectively, of the pulse sensors, is that the tooth of the disk (Fig. 5) can be made four times larger than the teeth of the disk 18 (Fig. 3). This means that due to the unlimitedly small tooth shape, the outer diameter of the disk 18 should be selected in the design of FIG. 3 is larger than in the embodiment according to FIG. 5. The division of the endless chain 10, respectively, of the toothed rack 16 should be chosen small, the number of teeth of the sprockets 6 and 7, respectively, of the gear 17 in this case should be chosen small. A pulse sensor with a disk 18 and the location of the clock sensors A and B, as shown in FIG. 5, can be performed with a large chain division, respectively, by dividing the rack, gears 6 and 7, respectively, gears, 17 with large teeth, and also with a small diameter of the pulse shaping disk 18. This ensures a long service life and creates conditions for the best operation of the pulse sensor and its drive.
