Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a loom control method for making a determination as to whether data necessary for loom control is appropriate using an external storage medium.

2. Description of the Related Art As disclosed in Japanese Patent Application Laid-Open No. 52-103559, a system for transmitting information between a host computer and each control computer of a large number of looms and centrally managing the large number of looms is known. It has been conventionally proposed. As communication information,
Operational weaving data such as operation time, machine stop time, weaving amount, remaining warp beam, operation data such as warp breakage, weft insertion error, etc., set weft insertion timing, set weft detection timing, set weft setting, etc. There is a condition, and by transmitting and receiving these pieces of information, the weaving state, warp beam consumption state, abnormality occurrence state, and the like of each loom are grasped by the host computer, and necessary work for each loom is performed based on this grasp.

[Problems to be Solved by the Invention] However, in any input of the loom control conditions such as the starting condition such as the machine rotation angle position at the time of starting, the machine stopping angle position, and the warp sending speed, the warp sending condition such as the warp tension, etc. It is necessary to rely on the transfer operation of the margin operator, and data transfer different from desired loom control conditions may be performed due to the manual intervention. When there is a loom whose operating efficiency is extremely low despite the fact that the same fabric is woven by a large number of looms, the cause is often the inconsistency of the loom control conditions due to the transfer error as described above. . Therefore, it is necessary to check the control conditions of the loom whose operating efficiency is extremely low. In this check, it is necessary to perform the operation of displaying the data on the display device and comparing the displayed data with the original data for each individual data. There is inevitably a very complicated and inefficient work efficiency,
Check errors are also likely to occur.

The present invention utilizes an external storage medium, such as a memory card, as disclosed in JP-A-52-99360, which makes it possible to simplify the construction of a mechanical and control system when using a host computer. Is to provide a loom control method capable of easily and accurately checking the loom.

Means for Solving the Problems According to the present invention, a data transfer function is provided between a loom control computer and an external storage medium, and desired comparison target data among the data in a specific loom is transmitted to the loom. Selected by the transfer operation of the control computer and transferred to the external storage medium, and the stored data in the transferred external storage medium and the comparison target data in the loom control computer of another loom are compared by the comparing means of the loom control computer. , And when the two do not match, this mismatch is displayed.

[Operation] The loom control computer transmits and receives the information to and from the external storage medium in response to the transfer command under the connection state with the external storage medium. The data specified by the transfer command in the loom control computer performing the transfer operation is transferred from the loom control computer to the external storage medium, and the transferred data is stored in the external storage medium. If the transferred external storage medium is connected to another loom control computer, it is possible to compare and determine the stored data in the external storage medium and the stored data of the loom control computer based on the comparison means in the loom control computer. Becomes When the difference between the two stored data is grasped by the comparison judgment, the inconsistency is displayed.

Hereinafter, an embodiment in which the present invention is applied to a jet loom will be described with reference to the drawings.

The loom control computers Ce and Cg installed in each loom Le, Lg (e = 1, 2, 3,..., E ≠ g) provide a transfer data selecting device 1, a transfer command device 2, a data rewriting device 3, and a display. The device 4 and the comparison command device 5 are connected, and a memory card 6 can be inserted and connected to the loom control computers Ce and Cg.
The transfer command device 2 is for instructing one of transfer from the loom control computers Ce and Cg to the memory card 6 and transfer from the memory card 6 to the loom control computers Ce and Cg. In the memory Me of the loom control computer Ce, the working weaving data group E such as warp beam diameter, warp breakage, weft insertion error and the like is taken in and stored as detection data from the detector, and warp tension, warp delivery speed, etc. Sending data group A, length measurement data group B such as weft insertion length, weft insertion start timing, weft insertion end timing, etc., and weft insertion data group C such as injection start timing and injection stop timing of main and sub weft insertion nozzles. , A start data group D such as a machine rotation angle position at the time of starting and a machine rotation angle position at the time of stopping the machine is captured and stored by an input setting operation of the data rewriting device 3.

As shown in FIG. 2, warp sending data A (1), A
(2) warp let-off data group A composed of · · · A (i) is stored in the address n _1, n ₂ ··· n _i of memory Me, measurement data B (1), B ( 2) ... B (j)
The length measurement data group B composed of the addresses ni _{+ 1} and ni _{+ 2}
... weft insertion data C (1), C (2) ... C in ni _{+ j}
(K). Weft insertion data group C is an address
ni + j _{+ 1} , ni + j _{+ 2} ... ni + j + k and start data D
The start data group D composed of (1), D (2)... D (l) has addresses ni + j + k _{+ 1} , ni + j + k _{+ 2.}
+ J + k + 1. The active weaving data group E is stored at an address other than the above.

Similarly, in the memory Mg of the loom Lg, the warp delivery data a
(1), a (2)... A (i) are the warp sending data group A ′ at addresses n ₁ , n _2.
n _i , and the length measurement data b (1), b (2)
The length measurement data group B 'composed of a (j) is stored at addresses ni _{+ 1} , ni _{+ 2} ... Ni _{+ j} and weft insertion data C (1), C

A start data group D 'composed of start data d (1), d (2)... D (l) is an address ni + j + k _{+ 1} , ni + j
+ K _{+ 2} ... Ni + j + k + 1. The operation weaving data group E 'is stored at an address other than the above.

If only the operating efficiency of the loom Lg is abnormally low among the looms Le and Lg that are weaving the same woven fabric, the loom showing the data group A ', B', C ', D' of the loom Lg and the normal operating efficiency In some cases, Le does not match the data groups A, B, C, and D, that is, the proper data groups A, B, C, and D are not used as the loom data groups.
Therefore, the data group A ', B', C ', D' of the loom Lg and the data group
A check for match or mismatch with A, B, C, and D is performed based on the flowchart of FIG.

First, the memory card 6 is inserted and connected to the loom control computer Ce of the loom Le exhibiting normal operation efficiency. The loom control computer Ce enters a transfer standby state in response to the insertion signal accompanying this insertion connection. Based on the transfer command by the operation of the transfer command device 2 and the designation of the transfer data group by the operation of the transfer data selection device 1, the loom control computer Ce transfers the specified transfer data groups A, B, C, D from the memory Me to the memory card. 6
Transfer to Thus the loom control computer Ce warp let-off data group A (1), A (2 ) ··· A (i) is transferred to the address m _1, m ₂ ··· m _i of the memory card 6.
Next, a length measurement data group B (1), B (2)... B (j)
To the addresses mi ₊₁ , mi ₊₂ ... Mi _{+ j} of the memory card 6,
The weft insertion data C (1), C (2)... C (k) are transferred to the addresses mi _{+ j + 1} , mi _{+ j + 2.}
(1), D (2)... D (l) are addresses mi + j + k _{+ 1} ,
mi + j + k _{+ 2} ... mi + j + k + 1

After inserting the memory card 6 storing the control data A, B, C and D of the loom Le into the loom Lg, the loom control computer Cg uses the comparison command device of the comparison command device 5 to store the data A (i) on the memory card 6 side. ₀ ) (i ₀ = 1,2... I), B (j ₀ ) (j

(L ₀ ) (l ₀ = 1,2... L) and stored data a on the loom Lg side
(I ₀ ) (i ₀ = 1,2... I), b (j ₀ ) (j ₀ = 1,2.
j), c (k ₀ ) (k ₀ = 1, 2,... k), d (l ₀ ) (l ₀ =
1, 2,... L). This comparison is sequentially performed in a one-to-one correspondence between the addresses m ₁ , m _{2 to} mi + j + k + ₁ on the memory card 6 and the addresses n ₁ , n _{2 to} ni + j + k + ₁ on the loom Lg, and non-coincidence data is displayed each time non-coincidence data is compared. Displayed on device 4. For example, if the data b (2) at the address ni _{+ 2} of the loom Le does not match the data B (2) at the address mi _{+ 2} of the memory card 6, the loom control computer
Cg displays the address ni _{+ 2} and the data b (2) on the display device 4.

Such defective data display indicates a setting failure of the control data in the loom Lg, and this setting failure can be specified as a cause of an abnormal decrease in the operating efficiency of the loom Lg. Therefore, the control data b displayed as defective data
By rewriting (2) to the appropriate control data B (2) by operating the data rewriting device 3, the control data of the loom Lg matches the appropriate control data of the loom Le, and the abnormal decrease in the operating efficiency of the loom Lg is eliminated. Is done. No defective data is displayed when the control data of the loom Lg matches the control data of the loom Le, and it is understood that the abnormal decrease in the operating efficiency of the loom Lg is not caused by a control data setting error. Is done. That is,
By using the memory card 6, it is possible to easily grasp the suitability of the control data of the loom, and by displaying the presence or absence of defective data, is it possible to determine whether the operating efficiency of the loom is reduced due to the control data setting defect. Can be determined.

The present invention is, of course, not limited to the above-described embodiment. For example, as shown in FIG. 4, each time the control data of the loom Le and the control data of the loom Lg are checked, the display of the defective data is performed. And the control data of the memory card 6 corresponding to the defective data may be transferred to the address of the defective data for replacement. Alternatively, when there is defective data, the display of the presence of the defective data may be performed after the completion of all the checks, and all the control data of the memory card 6 may be transferred collectively.

Further, a data check may be performed when control data is input to the loom, or data of an abnormal loom may be transferred to a memory card to perform a data check on a normal loom.

[Effects of the Invention] As described above in detail, the present invention compares the storage data transferred in the external storage medium with the comparison target data in the loom control computer of another loom by the comparing means of the loom control computer. At the same time, if the two do not match, this mismatch is displayed, so that it is possible to easily grasp whether or not the cause of the operation abnormality of the loom is due to a setting error of the control data, and this This provides an excellent effect that an appropriate measure can be taken based on the grasp result.
