Description

Method and accessory configuration for adjusting warp knitting machine

The present invention relates to a method for adjusting a warp knitting machine in which a knitting tool zone is monitored and an adjustment signal is generated.

The invention also relates to an auxiliary device for adjusting a warp knitting machine, having an auxiliary device for monitoring the knitting tool area, and an actuating element or the like for generating an adjustment signal.

In the operation of a warp knitting machine, the knitting tools work together to form a loop. For example, a guide pin or other guide guide must be moved relative to the knitting needle, also referred to as a working needle, to form a loop. The knitting needle series are arranged on a knitting needle bar. The series of guide pins are provided on one or a plurality of guide rods. Depending on the so-called fineness of the machine, i.e. the number of knitting needles per width, the knitting needles are spaced apart from each other by a small distance.

Through this gap, also known as the "needle lane", the yarn guides must pass through the knitting needles without collision. It is therefore important that, in the return or natural position of the machine, the individual yarn guides are positioned as far as possible between the two knitting needles and the yarn guides are adjusted accordingly. Another possibility is to perform a known "pattern movement" when the machine is stationary. This causes the yarn guides to be adjusted near one of the needles of the needle bar.

To make the appropriate settings, the operator uses a magnifying glass through which the knitting tool area is viewed. Depending on the perceived position of the braiding tools relative to one another, the operator activates different switches or buttons on a control panel to generate an adjustment signal. The control panel is connected to the controller of the warp knitting machine via a cable, which changes the position of a bar according to the adjustment signal.

The CN 104 131 410 B patent discloses the use of a control panel that is wirelessly connected to the controller of the warp knitting machine.

Simultaneous use of the magnifying glass and the control panel requires a certain level of proficiency in the operator. In many cases, most operators must also be active at the same time when controlling on the control panel, such as turning a start switch to a position and keeping it there, while moving certain buttons.

The object of the present invention is to simplify the work of adjusting a warp knitting machine.

This object is achieved in a program as described above in which a camera is used to monitor the knitting tool zone and the knitting tool zone is presented on a display.

The camera and the display enable the braiding tool area to be viewed. The operator can monitor the movement of the respective bars and the knitting tool attached thereto to generate the adjustment signals.

Preferably, a camera having a variable focal length function is used. The braiding tools can then be shown in an enlarged form on the display so that the operator can easily identify how the braiding tools are positioned relative to one another. A magnifying glass will no longer be needed.

Preferably, a display is used in which the actuating elements for generating the adjustment signals are assigned. Therefore, the operator only needs to manipulate the display or a device carrying the display to generate the desired adjustment signal. This means that it can easily and immediately detect the effect of the adjustment signal caused.

It is preferred to use a touch sensitive display having a display field designated as an actuating element. Therefore, the display is designed as a "touch screen". For example, by tapping the right edge of the display, one of the particular bars can be moved to the right and the left edge of the display can be tapped to move the corresponding bar to the left.

Preferably, the designated areas are represented on the display as such. These designated areas can be marked, for example, "left" and "right" to simplify the work of the operator.

A communication device having a camera is preferably used, in particular a mobile phone or a portable computer, such as a tablet computer. Cameras are already installed in most mobile phones. Many portable computers, especially so-called tablets, also have built-in cameras. Both communication devices can also operate applications, so-called "apps", so the adjustment of the warp knitting machine will be supported by this application. When the actuating elements are actuated, the application forwards the corresponding control command as a tuning signal to the warp knitting machine.

Preferably, the communication device is coupled to a controller of the warp knitting machine by a wireless device. For example, this connection can be caused via a WLAN. To be able to do so, the communication device and the warp knitting machine, or more precisely the controller of the warp knitting machine, are provided with suitable interfaces.

Alternatively, a wired connection can also be used. For example, it is possible to use a fixedly mounted and hardwired camera that will send its image to the display. Thereby, the bar will be able to be adjusted. Of course, it is also possible to use a fixed camera that wirelessly transmits corresponding image information to the display.

Preferably, the display is part of a display facility and a portion of the display facility is attached to the warp knitting machine. The display facility can in principle have a plurality of displays. For example, one display can be located on the communication device and the other display can be placed on the warp knitting machine. In this case, a display on the warp knitting machine can be used, which has been provided to the controller of the warp knitting machine. The operator can select the location on the display where the knitting tool zone is to be viewed.

In this case, it is preferred to connect the communication device to a remote maintenance device. By using remote maintenance, the adjustment can be made by a remote maintenance device or remote service from a geographically remote point, such as by the manufacturer of the warp knitting machine.

The object can be achieved by an auxiliary facility as described above, wherein the auxiliary device has a camera for taking in a knitting tool area, and a display system is provided, on which the knitting tool area can be displayed. .

Using the display, the operator can display the knitting tool area and check if the adjustment signals have the desired effect. The camera can also be moved to different positions of the warp knitting machine and, for example, allows the knitting tool area to be monitored by the front or rear for adjustment.

Preferably, the camera has a variable zoom function. The braiding tool area can be displayed on the display in an enlarged image, which facilitates the adjustment.

Preferably, the display is designed as a touch sensitive display and the control elements are formed by designated areas of the display. The adjustment signals can be generated by touching the display, or more precisely, touching a designated area of the display.

Preferably, the camera is coupled to a communication device, particularly a mobile phone or a portable computer, such as a tablet computer. The operator then only has to keep the communication device on the machine and position it so that the camera can ingest the knitting tool area. Anyone, for example using the communication device, can also generate the required adjustment signals.

It would also be advantageous if the auxiliary device was wirelessly connected to one of the warp knitting machines. This wireless connection can be established, for example, using a WLAN connection. What is only required for this purpose is that the warp knitting machine and the auxiliary device are each provided with a suitable interface. In this case, it can also be provided, for example, that the knitting tool area is displayed on a display on the warp knitting machine. This display can in many cases be used as part of the component of the controller of the warp knitting machine. These control elements for generating adjustment signals can also be provided herein.

A warp knitting machine 1 includes a guide rod 2 on which a plurality of guide pins 3 are arranged. Instead of the guide pins 3, other yarn guides may be provided.

Further, the warp knitting machine comprises a knitting needle bar 4 on which a series of knitting needles 5 are arranged and arranged one upon another. When the warp knitting machine 1 is in operation, the needles 3 and the knitting needles 5 cooperate to form a loop. For a portion of this procedure, for example, the guide pins 3 will pass near the knitting needles 5.

The pins 3 are separated from each other by a small distance. For example, in the case of a fineness level of E20, 20 guide pins 3 will be provided for each turn. Therefore, the distance between the guide pins is on a size scale of about 1 mm. The same applies to the spacing of the knitting needles 5 relative to each other. In order to facilitate the interaction of the guide pins 3 with one of the knitting needles 5, the guide pins 3 are preferably arranged in the center as far as possible with respect to the knitting needles 5.

The illustration of the warp knitting machine is greatly simplified here. In fact, more knitting tools will be provided, such as shared hooks, combing hooks and the like. The illustrations of such weaving tools have been omitted for clarity. These weaving tools must be adjusted in the same way relative to other weaving tools.

The warp knitting machine 1 comprises a machine controller 6 comprising a display 7. The machine controller 6 is also provided with an antenna 8 or other receiving device for a WLAN, ie a wireless network.

In order to be able to make the required adjustments, an operator must monitor the knitting tool area and generate an adjustment signal based on the position of the needle 3 and the knitting needle 5 relative to each other, and the machine controller 6 will utilize the adjustment signals. A signal is used to adjust the position of the guide bar 2 and the knitting needle bar 4 relative to each other. In most cases, it suffices to adjust the position of one of the two bars 2, 4 parallel to its longitudinal direction. The adjustment signals may for example be pulses, wherein at each pulse the machine controller 6 shifts the particular bars 2, 4 being addressed or controlled by a fraction of a millimeter, for example 0.05 mm or 0.1 mm. The operator can visually monitor whether the adjustments made to the guide pins 3 and the knitting needles 5 relative to each other are successfully positioned, or whether further adjustment is required.

This monitoring was previously performed through a magnifying glass, so that the knitting tool area can be seen in a large proportion. However, this processing method is more troublesome.

In front of the warp knitting machine 1, an auxiliary device 9 for viewing the knitting tool area is shown enlarged. The auxiliary device forms a part for adjusting the auxiliary equipment of the warp knitting machine 1, or even completely forms the auxiliary facility. This is further explained later.

The auxiliary device 9 includes a camera 10 and a display 11. The camera 10 includes a variable zoom function, i.e., the braiding tool region can be presented on the display 11 in an enlarged form, thus the needle guide 2 having the guide pins 3 and the braid having the knitting needles 5 The needle bar 4 can be better identified. Preferably, the magnification can be adjusted to enable the operator to display the knitting needle regions, i.e., the knitting needles 3, 5, in a desired size.

The auxiliary device can be designed, for example, as a mobile communication device, such as a mobile phone, such as a "smart phone" or a portable computer, such as a tablet personal computer, a notebook computer, or the like.

The display 11 is designed as a touch sensitive display. The display 11 contains certain areas that are designed as control elements. The areas 12, 13 can be displayed on the display 11. These areas 12, 13 may also display information that would alert them to their utility. In this embodiment, the area 12 is labeled "L" and the area 13 is labeled "R". Therefore, if the light is buckled on the area 12, the guide rod 2 will move to the left, and if it is lightly buckled on the area 13, the guide rod 2 will move to the right.

In a method not shown in detail, a list of available bars can be pre-displayed on the display, and with a particular area of the touch-sensitive display 11, appropriate bars can be selected.

The corresponding adjustment signal is transmitted to the antenna 8 of the machine controller 6, so that the machine controller 6 can cause the desired action of the guide 2 or the knitting needle 4.

It can also be provided such that the image system displayed on the display 11 of the auxiliary device can also or only be displayed on the display 7 of the machine controller 6. If the display 7 is also designed as a touch-sensitive display, the adjustment can also be directly performed after one of the auxiliary devices is properly positioned so that the camera 10 records the knitting tool area having the knitting tools 3, 5. The grounding is performed on the machine controller 6.

It may also be provided with information relating to the image of the braided tool zone having the braiding tools 3, 5 being transmitted to a remote device, such as one of the manufacturers of the warp knitting machine. The adjustment can also be performed over a long distance by sending back one of the corresponding adjustment signals.

For this adjustment, only the auxiliary device 9 assigned to the warp knitting machine 1 is required to use appropriate measured values. This can be achieved, for example, by an IP address. It also requires that the auxiliary device, as previously described, be assigned to a particular bar that will be adjusted in a particular situation. But this is also easy and feasible.

To enable this adjustment, a so-called application ("app") can operate on the auxiliary device 9. This app, or application, can be provided by the manufacturer of the warp knitting machine.
