Problems solved by technology

Depending on the setting of the angle of repose or the number of revolutions of the loom, sometimes the load of the frame driving motor is too large, or the motor cannot follow the desired opening curve, or the motor or the transmission system may be damaged due to the excessive load of the motor.
[0003] However, since the operator cannot understand the actual motor load under the set shedding movement conditions before weaving, after setting the shedding conditions, it is necessary to carry out trial weaving to confirm the load generation situation or the state of the shedding movement
The result is a suitable setting of the shedding movement regulation or its accompanying adjustment of the loom, especially the adjustment of the loom speed is complicated

Embodiment 1

[0039] The first embodiment is based on inputting the opening motion conditions of each palm frame 2 to the setter 5. When the palm frame 2 is driven under the set opening motion conditions, the motor 3 corresponding to each palm frame 2 is obtained. An example of the load applied on and displayed on the display 9.

[0040] In order to display the load of the motor 3, a plurality of databases corresponding to a plurality of opening motion conditions, for example, each weave (tissue) are stored in the memory 7. This database is based on the actual weaving carried out under each shedding movement condition, and accumulates the data of the actual load of the motor 3 when the palm frame 2 is driven under each shedding movement condition. figure 2 The distribution form shown is expressed in the form of a table.

[0041] figure 2 The database, as shown in the box in the upper paragraph, is the middle position of the top dead center and bottom dead center (rotation angle of the loom mai...

Embodiment 2

[0062] In the second embodiment, in addition to the input of the opening motion conditions, the input of the allowable load value of the motor 3 is also used. According to the set opening motion conditions, the database and the load allowable value, the load contraction of the motor 3 can be obtained below the allowable value. Examples of opening movement conditions and displayed on the display 9.

[0063] On the setting device 5, use Figure 4 In the display screen shown, input the allowable value of the load of the motor 3, such as "80%", and input as the opening movement condition, for example, the middle position of the frame number 1 is 290° and the opening amount is 120 mm. When these set values ​​are input to the setter 5, the arithmetic unit 8 extracts recommended opening motion conditions that are lower than the input load allowance value from the database stored in the memory 7.

[0064] Specifically, when the opening movement conditions stored in the database of the memo...

Embodiment 3

[0071] Example 3, as described in the above-mentioned Example 2, is that in addition to the open motion conditions, the load allowance of the motor 3 can be input and the open motion conditions that shrink it below the allowable value of the load of the motor 3 can be obtained. The obtained recommended opening motion conditions are output to the controller 6 and the recommended opening motion conditions are automatically set in the controller 6 as an example.

[0072] Therefore, the arithmetic unit 8 obtains the recommended opening motion condition, inputs the set value of the recommended opening motion condition to the controller 6, and automatically sets it there. This eases the burden on the operator to adjust the loom. The display 9 displays the calculated recommended opening motion conditions with numerical values, curves (opening curves), or a combination of numerical values ​​and curves (opening curves), but in Embodiment 3, since the controller 6 automatically sets The s...

Abstract

An electric shedding apparatus (1) for a loom drives a plurality of heald frames (2) with dedicated motors (3). The electric shedding apparatus (1) includes a setter (5) that sets a shedding motion condition including a plurality of items for driving each heald frame (2), a controller (6) that controls the rotation of each motor (3) on the basis of the set shedding motion condition, a memory (7) that stores a database including a plurality of shedding motion conditions and loads applied to each motor (3) if the corresponding heald frame (2) is driven under the shedding motion conditions, and a calculator (8) that determines a load corresponding to the set shedding motion condition on the basis of the set shedding motion condition and the database.

Description

Technical field [0001] The present invention relates to a device for appropriately setting opening movement conditions on an electric opening device that drives a plurality of palm frames with respective dedicated motors. Background technique [0002] The electric shedding device of the loom uses each dedicated motor to drive multiple palm frames, and drives each palm frame according to a prescribed opening curve, but its opening curve passes through corresponding to the middle position, that is, corresponds to the vertical movement direction of the palm frame. The rotation angle of the main shaft of the loom (the same below) at the middle position of the, and the angle of repose (dwell) of the maximum opening on the upper side or the maximum opening on the lower side. Depending on the setting of the angle of repose or the number of revolutions of the loom, the motor for driving the frame may be overloaded, or the motor cannot follow the desired opening curve, or the motor or the...
