Background technology
In loom, shed forming device is used to form meridianpiston, forms shed open and be introduced in the shed open to allow parallel between meridianpiston.Known shed forming device usually drives at least two heald frames, and comprises and be used for each heald frame so that make transmission mechanism that heald frame moves up and down and driven the drive rod that is used for the transmission mechanism of heald frame with driving by drive unit.Transmission mechanism is driven by drive unit usually, for example dobbies, cam box, eccentric mechanism or any other drive unit.
Drive some drive rods as the drive unit describing among EP 0 742 298 A2, each heald frame is associated with a drive rod usually.For each heald frame, in this case, transmission mechanism comprises vertically rod of the rod that is connected to drive rod, first hinge-rod, horizon bar, second hinge-rod and two, and the crankmotion transmission that is used for the hinge-rod that will be associated is moving up and down of heald frame.EP 1 613 800 B1 have described has three hinge-rods and three vertically excellent transmission mechanisms.
The shape of shed open has been determined in the motion of all heald frames together.The motion amplitude of the motion of heald frame, particularly heald frame depends on different parameters, for example especially depends on rod and/or the length of hinge-rod, the moving line of drive rod and/or the coupled position of transmission mechanism and drive rod of transmission mechanism.The desired motion amplitude of heald frame can be selected according to different parameters, the type of Weaving pattern, braiding speed, heald frame type and/or the transmission mechanism of textile material for example to be woven, employed heald frame quantity, expectation.
Regulating a kind of of integrated box movement amplitude may be the moving line of regulating by the drive unit driven drive rod.The type that depends on drive unit becomes known for changing the method and apparatus of the moving line of drive rod.But, can't under the situation of not dismantling drive unit, change moving line usually.
Another that regulate the integrated box movement amplitude may be to regulate the length of the hinge-rod of transmission mechanism and/or rod and/or change hinge-rod and/or the position of the interlinkage of rod.In fact, select transmission mechanism at the loom assembly process, and no longer change transmission mechanism subsequently.
Generally speaking, transmission mechanism is connected to drive rod, and drive rod is driven by the connector that the drive unit utilization is set in coupled position.Can set the coupled position of the drive rod that connector makes transmission mechanism be connected to be associated can move, and is used for the amplitude of accommodation.If must move some heald frames, then can differently set the coupled position of expectation for different heald frames.In fact, in case loom is assembled, then the setting of the integrated box movement amplitude of loom is only carried out by regulating the coupled position that can set connector.
In fact can use form, according to the type of drive unit and/or the design of transmission mechanism, limit with reference to coupled position for the connector set between transmission mechanism and the drive rod in form, the shed open that is used to expect is set.Can for example provide with reference to the distance of coupled position with reference to coupled position apart from the drive rod end by providing this.
In order to regulate coupled position according to these forms, known use ruler is set at different coupled position the reference coupled position that is associated.In addition, JP 64-22789 discloses and scale has been set with easy adjusting on drive rod.But the adjusting of coupled position (except others) needs still to know that the type of drive unit, form that the transmission mechanism design and use are associated determine the coupled position of expectation.
Summary of the invention
The objective of the invention is to not need knowing drive unit, do not need to know the transmission mechanism design and/or not need to use the mode of form to set coupled position easily.Another purpose is to provide a kind of shed forming device of easy setting coupled position.
Purpose of the present invention is realized that by a kind of shed opening device wherein transmission mechanism and drive rod are connected in specific coupled position by connector, and wherein drive rod is provided with at least one indication that is used for reference to coupled position.
