DESCRIPTION:
BRIEF SUMMARY
BACKGROUND AND SUMMARY OF THE INVENTION
The instant invention relates to a process to service work stations of spinning or doubling machines by means of a plurality of service units capable of travelling alongside the work stations as well as to a device to carry out this process.
In spinning or doubling machines an end section is always configured as a service section through which the machine is connected to the electrical utilities network, to an air exhaust line, etc. In addition, fully automated machines are equipped with feeding and waste disposal equipment, such as for example equipment to supply the machines with empty bobbins or to remove the full bobbins. Because of the space required by this equipment, the servicing equipment can travel around the machine only at one of its ends.
The travelling equipment used to service the work station of spinning or doubling machines must be inspected from time to time to ensure that it remains operational. Since the side of the service units which faces the spinning stations must be accessible for this purpose, the service units are run to the end of the machine where said service units can switch over to the other side of said machine. In this arc segment the desired accessibility exists without interfering with the spinning stations.
However, this has the disadvantage that the spinning stations cannot be serviced during the inspection, not even by a second service unit, since the service unit to be inspected blocks the way from one side of the machine to the other. This leads to outages and stoppages of the spinning stations for extended periods, resulting in production losses.
It is therefore the objective of the instant invention to create a process and a device which make it possible to carry out the servicing of the spinning stations continuously, also during inspections of the servicing equipment.
This objective is attained by the invention in one exemplary embodiment thereof in that the service unit to be inspected is brought into an inspection position, crosswise to its usual direction of travel, in which also its side to be serviced which is otherwise turned towards the machine is rendered accessible and in which its path of travel is opened to another servicing unit, whereby another servicing unit travels into the usual path of travel of the service unit being temporarily inspected or adjusted and takes over the servicing tasks of the work stations now rendered accessible to it until the inspected service unit is brought back from its inspection position into its operative position after completion of the inspection. In this manner one or several service units can take over the servicing tasks of the work stations of a service unit to be inspected, without the service unit to be inspected blocking access for such and without it being necessary for the working service unit to return to a starting position, which would otherwise result in temporary interruption of the servicing process. In this manner, no work stations are deprived service by a service unit for the duration of the inspection.
When more than two service units operate in a production line which contains several machines connected to each other by a working section, it is advisable to distribute the task of servicing the work stations normally serviced by the service unit being inspected among the remaining service units in order to achieve an even work load distribution among such remaining service units.
Several of the functions of a service unit can only be checked when the latter is connected to energy sources. For this reason it is preferable if the service units, when they are in their inspection position, remain connected to the supply lines. If the service unit is designed so that, when in operation, it can be called by malfunctioning work stations to perform a service task, a further variation of the process according to this invention provides for the service unit to be uncoupled by a trip control line during or before movement into its inspection position.
