In a spinning mill in which a bobbin from a spinning frame is mounted on a bobbin tray and sent to a winder, a package doffed from the winder is loaded on a hanger and then the package is mounted on a package tray, recording media is provided on the bobbin tray, on the hanger and the package tray, respectively. Frame numbers and spindle numbers which are production origin information of bobbins are written on the recording medium so that the production origin information can be controlled and the records can be grasped.
In a spinning mill in which a bobbin from a spinning frame is mounted on a bobbin tray and sent to a winder, a package doffed from the winder is loaded on a hanger and carried, after which it is unloaded and then mounted on a package tray, which is supplied to an inspection station, a production control system comprising:
A production control system for use in a spinning mill wherein a bobbin is mounted on a bobbin tray and sent to a winder, and a package doffed from the winder is carried by a hanger, unloaded, mounted on a package tray, and carried to an inspection station, the production control system comprising:
A package handling apparatus for use with a multi-spindle winding unit having a stock-line for stocking full packages doffed from the spindles on one side of the multi-spindle winding unit, a carrying conveyor on a side of the stock line opposite the winding unit and a shutter between the stock line and the carrying conveyor, the package handling apparatus comprising:

The present invention relates to a quality and production control system in a spinning mill.
The present invention further relates to a package carrying apparatus operated when wound packages doffed by an automatic winder are carried to a lifting device, and particularly to a package carrying apparatus which can grasp information such as information by which spindle a wound package was wound.
Generally, in a spinning mill, raw cotton is received to produce yarns through various steps such as mixing and blowing, combing, drawing, roving, spinning, unwinding, inspection, packaging, shipment from warehouse, etc. Then, the produced yarns are delivered to the post-steps outside the mill, for example, such as weaving, dyeing, etc.
FIG. 1 is a schematic view of a quality and production control system according to an embodiment of the present invention;
FIG. 2 is a plan view showing the structure of a spinning winder;
FIG. 3 is a plan view showing a tray for a spinning bobbin;
The present invention will be described hereinafter by way of embodiments shown in the drawings.
FIG. 1 shows the outline of a system of steps from spinning frames to a warehouse in a spinning mill.
In FIG. 1, reference numeral 1 designates a spinning frame and numeral 2 designates a winder. A plurality (forty in this embodiment) of spinning frames 1 and winders 2 are provided. A set of the spinning frame 1 and the winder 2 are directly connected to each other to constitute a so-called spinning winder 2. Each of the spinning frames 1 and winders 2 comprises a number of units. A constant-length device 35 is provided on each winder 2.
