Although the details of the knitted fabric quality control device 100 will be described later, each main part is equipped in a state of being supported by the frame 60 to which the exterior panel 61 is attached, and the main part thereof is also shown in FIG. As shown, a measuring mechanism unit 1, a moving mechanism unit 2, a sorting mechanism unit 4, a control device 5 for controlling the operation of these, and the like are provided.

The weighing mechanism unit 1 has a weighing table 11 on which the knitted fabric P discharged from the knitting machine 70 and charged into the input port 10a is placed, and the weight of the knitted fabric P placed on the weighing table 11 Is configured to measure.
The weighing table 11 receives the knitted fabric P dropped through the input port 10a, and is arranged below the input port 10a so that the received knitted fabric P is placed on the upper surface. ..
The weighing table 11 is mounted on the electronic weighing device 12, and the electronic weighing device 12 measures the weight of the knitted fabric P placed on the measuring table 11, and the weighing result is input to the control device 5.

Peripheral walls 15 and 16 are erected on the outer peripheral edge of the measuring table 11 to prevent the knitted fabric P from falling from the measuring table 11. Further, the peripheral walls 15 and 16 are formed on a pair of side walls 15 facing the moving direction X, which will be described later, along a transverse direction perpendicular to the moving direction X, and on the rear side (lower right side in FIG. 3) along the moving direction X. An arranged rear wall 16 is provided.
Further, the rear wall 16 is configured as a comb-shaped wall in which a plurality of comb tooth portions 16a extending upward from the rear edge portion of the measuring table 11 are arranged side by side at regular intervals.

The moving mechanism unit 2 slides the moving bodies 21 and 28 between the weighing table 11 and the payout table 40 arranged adjacent thereto, and pushes and slides the knitted fabric P by the moving bodies 21 and 28. It is configured to be mobile.
In the present application, the direction in which the moving bodies 21 and 28 are moved by the moving mechanism unit 2 is the moving direction X, and in the moving direction X, the payout table 40 side is the front side when viewed from the weighing table 11, and the payout table 40 is used. The side of the weighing platform 11 is the rear side.

As the moving bodies 21 and 28, a first moving body 21 arranged on the rear side and a second moving body 28 arranged on the front side are provided along the moving direction X.
The first moving body 21 and the second moving body 28 are composed of plate-shaped members orthogonal to the moving direction X in a state where the lower ends are close to the upper surfaces of the measuring table 11 and the payout table 40. The upper ends of the moving body 21 and the second moving body 28 are fixed to sliders 22 and 29 slidably mounted on a pair of shafts 23 and 30 extending along the moving direction X, respectively.

The sliders 22 and 29 are coupled to the moving belts 24 and 31, and the moving belts 24 and 31 are rotated around the drive pulleys of the moving motors 25 and 32 fixed to one end side of the shafts 23 and 30. ing.
Therefore, the first moving body 21 and the second moving body 28 fixed to the sliders 22 and 29 are moved by rotationally driving the moving motors 25 and 32 by the drive control unit 51 in which the control device 5 functions. It can be moved along the direction X. Then, by moving the first moving body 21 and the second moving body 28 along the moving direction X, the knitted fabric P is pushed and slid by the first moving body 21 and the second moving body 28. Can be moved along the moving direction X on the weighing table 11 and the payout table 40.

Further, the first moving body 21 is configured as a comb-shaped moving body formed in a comb shape in which a plurality of comb tooth portions 21a hanging downward are arranged side by side at regular intervals. Then, the comb tooth portion 21a functions as a device that abuts the knitted fabric P on the measuring table 11 and the payout table 40 from the side and pushes and slides them as the first moving body 21 moves.
The comb tooth portion 21a of the first moving body 21 is arranged so as not to overlap with the comb tooth portion 16a of the rear wall 16 also formed in a comb shape in the moving direction X view. Then, when moving the first moving body 21 in the moving direction X, the position on the rear side of the rear wall 16 (for example, the position of the first moving body 21 shown in FIGS. 5, 7, or 10) is set as the initial position. , From the initial position, it passes through the installation position of the rear wall 16 and is moved to a position on the front side of the rear wall 16 (for example, the position of the first moving body 21 shown in FIG. 6, FIG. 8, or FIG. 9). be able to.

Further, the first moving body 21 is provided with a flat plate-shaped cover portion 21b extending from the upper end of the plurality of comb tooth portions 21a arranged side by side toward the front side. Then, the cover portion 21b of the first moving body 21 arranged at the initial position covers the upper part of the comb tooth portion 16a of the rear peripheral wall 16. Therefore, it is possible to prevent the knitted fabric P thrown into the loading port 10a from being caught on the upper end of the comb tooth portion 16a of the rear peripheral wall 16 and to preferably guide the knitted fabric P on the measuring table 11.

On the other hand, the second moving body 28 has a flat plate portion 28a that hangs downward. Then, the flat plate portion 28a functions as a device that abuts and pushes the knitted fabric P on the measuring table 11 and the payout table 40 from the side as the second moving body 28 moves.
When moving the second moving body 28 in the moving direction X, the vicinity of the inside of the front side of the measuring table 11 (for example, the position of the second moving body 28 shown in FIG. 5 or 6) is set as the initial position, and the position is rearward from the initial position. It can be moved to the side (for example, the position of the second moving body 28 shown in FIG. 7 or 8) or the front side position (for example, the position of the second moving body 28 shown in FIG. 9, FIG. 10, or FIG. 11). ..

Further, the second moving body 28 is provided with a flat plate-shaped cover portion 28b extending from the upper end of the flat plate portion 28a toward the front side. Then, even when the second moving body 28 moves from the initial position toward the rear side, the space on the front side of the flat plate portion 28a is partitioned by the cover portion 28b with respect to the input port 10a. Therefore, it is possible to prevent the knitted fabric P charged into the loading port 10a from being erroneously guided to the front side of the flat plate portion 28a, and to preferably guide the knitted fabric P onto the measuring table 11 on the rear side of the flat plate portion 28a. can do.

The moving mechanism unit 2 is a pre-weighing movement operation performed by the drive control unit 51 of the control device 5 before the weighing mechanism unit 1 measures the weight of the knitted fabric P, and the measuring mechanism unit 1 measures the weight of the knitted fabric P. It is configured to perform the post-weighing movement operation that is performed later.

The pre-weighing movement operation is the time from when the weighing mechanism 1 detects that the knitted fabric P has been loaded into the weighing table 11 from the loading port 10a until the posture of the loaded knitted fabric P stabilizes (for example, 3). The knitted fabric P placed on the weighing table 11 is placed in the substantially central portion of the weighing table 11 after the lapse of seconds) and before the weight measurement of the knitted fabric P by the weighing mechanism unit 1. It is a pulling action.

In this pre-weighing movement operation, the first moving body 21 is moved from the initial position as shown in FIG. 5 to a position slightly before the central portion of the weighing table 11 as shown in FIG. In the operation of moving the knitted fabric P placed unevenly to the rear side toward the central portion, and the operation of moving the second moving body 28 from the initial position as shown in FIG. 5 to the substantially central portion of the weighing table 11 as shown in FIG. By moving it to a position slightly in front of it, the operation of moving the knitted fabric P, which is biasedly placed on the front side on the weighing table 11, toward the center portion is alternately repeated a predetermined number of times.

By performing such a pre-weighing movement operation, the knitted fabric P that has been thrown into the loading port 10a and placed on the weighing table 11 is provided around the weighing table 11 before the weighing mechanism unit 1. It is separated from the side wall 15 and the rear wall 16 and brought to the substantially central portion of the measuring table 11. As a result, contact of the knitted fabric P with the peripheral walls 15 and 16 and the moving bodies 21 and 28 at the time of subsequent weighing is suppressed. Therefore, the deterioration of the weighing accuracy of the measuring mechanism unit 1 due to such contact is surely prevented, and the weight of the knitted fabric P is accurately measured.
The method of such pre-weighing movement operation can be changed as appropriate. Further, the pre-weighing movement operation may be omitted as appropriate.

Then, the weight of the knitted fabric P is measured by the weighing mechanism unit 1 after the pre-weighing movement operation. At the time of weighing by the measuring mechanism unit 1, the moving mechanism unit 2 positions each of the first moving body 21 and the second moving body 28 at the initial positions as shown in FIG. At this time, the first moving body 21 is retracted to the outside of the rear wall 15 when viewed from the measuring table 11. As a result, the contact of the knitted fabric P with the first moving body 21 at the time of weighing by the measuring mechanism unit 1 is surely prevented.

The post-weighing movement operation is performed at the timing immediately after the weight measurement of the knitted fabric P by the weighing mechanism unit 1, and the knitted fabric P after the weighing by the measuring mechanism unit 1 is arranged adjacent to the front side from the weighing table 11. It is an operation of transferring to the departure table 40.

In such a post-weighing movement operation, first, the first moving body 21 and the second moving body 28 at the initial positions as shown in FIG. 5 are sandwiched between the substantially central portion of the weighing table 11 as shown in FIG. By moving each to the position, the knitted fabric P located in the substantially central portion of the weighing table 11 is sandwiched between the first moving body 21 and the second moving body 28, and then the first moving body 21 and the first moving body 21 The operation of moving the second moving body 28 and the second moving body 28 to the substantially central portion of the payout table 40 as shown in FIG. 9 is performed. As a result, the knitted fabric P placed on the weighing table 11 is sandwiched between the comb tooth portion 21a of the first moving body 21 and the flat plate portion 28a of the second moving body 28, and the substantially central portion on the payout table 40. Can be moved to. Further, after the knitted fabric P is moved onto the payout table 40, as shown in FIG. 10, the comb tooth portion 21a of the first moving body 21 is moved to a position rearward from the rear wall 16 and is a second. 2 The flat plate portion 28a of the moving body 28 is moved to a position on the front side of the payout table 40, so that the comb tooth portion 21a and the flat plate portion 28a are moved with respect to the rotational operation of the payout table 40 of the sorting mechanism unit 4, which will be described later. Interference is avoided.
The method of such post-weighing movement operation can be changed as appropriate. Further, when the weighing table 11 and the payout table 40 are used in combination, the post-weighing movement operation can be omitted.

The sorting mechanism unit 4 has a payout table 40 on which the knitted fabric P after weighing by the measuring mechanism unit 1 is placed, and the quality determination unit 52 of the knitted fabric P placed on the payout table 40 is determined later. Based on the results, it is configured to sort out good products and defective products and pay them out.

The payout table 40 is fixed to the lower surface thereof and is rotatably supported around the rotating shaft portion 41 along the moving direction X, and the rotating shaft portion 41 is connected to the rotating motor 42. Then, the rotary motor 42 is rotationally driven by the drive control unit 51 in which the control device 5 functions, so that the payout table 40 is tilted in an arbitrary direction, and the knitted fabric P placed on the payout table 40 is arbitrarily selected. Can be slid down in the direction of.

Then, as shown in FIG. 11, the sorting mechanism unit 4 tilts the payout table 40 to one side where the non-defective product payout box 65 (an example of the non-defective product payout unit) is provided, and places the non-defective product on the payout table 40. The non-defective product payout operation of sliding the knitted fabric P of the above into the non-defective product payout box 65 can be executed. Further, although not shown, the defective knitted fabric P placed on the defective product payout table 40 by inclining the payout table 40 to the other side provided with the defective product payout box 66 (an example of the defective product payout unit). Can be executed for the defective product dispensing operation, which slides the defective product into the defective product dispensing box 66. Further, the defective product payout box 66 is arranged on the rear side of the non-defective product payout box 65, and the defective knitted fabric P that has slipped off the payout table 40 is once guided by the inclined guide plate 45 to pay out the defective product. It is put into the box 66.
Further, a partition plate 62 is provided to partition the side where the non-defective product payout box 65 is provided and the side where the defective product payout box 66 is provided. As a result, the good product and the defective product of the knitted fabric P that has been paid out can be reliably distinguished.
The weighing table 11 and the payout table 40 can also be used as one. In this case, the knitted fabric P placed on the weighing table 11 can be directly held by a robot arm or the like so as to be sorted and dispensed into a non-defective product payout box 65 and a defective product payout box 66.

Specifically, the quality determination unit 52 determines that the knitted fabric P is placed on the measuring table 11 of the measuring mechanism unit 1 when the measured value of the measuring mechanism unit 1 exceeds the preset minimum set weight, and knits the fabric. The measured value of the weighing mechanism unit 1 at the time when the time (for example, 3 seconds) in which the placed knitted fabric P stabilizes after the determination that the woven fabric P is placed has elapsed is recognized as the weight of the knitted fabric P. Then, when the weight of the knitted fabric P measured by the measuring mechanism unit 1 is within the preset set weight range, the knitted fabric P is determined to be a good product. Further, when the weight of the knitted fabric P measured by the weighing mechanism unit 1 is equal to or less than the lower limit value or more than the upper limit value of the set weight range, the knitting machine 70 has broken yarn or clogged yarn. Or, since it is predicted that a plurality of knitted fabrics P are simultaneously paid out due to poor discharge of the knitting machine 70, the knitted fabric P is determined to be a defective product. In the present embodiment, when a plurality of knitted fabrics P are paid out at the same time, it is determined as a defective product. For example, the weight of the knitted fabrics P measured by the measuring mechanism unit 1 is two or more. When two or more knitted fabrics P are paid out at the same time when the woven fabric P is within the preset weight range, it is possible to judge the two or more knitted fabrics P as non-defective products. it can.
Then, the sorting mechanism unit 4 sorts the knitted fabric P into a non-defective product and a defective product based on the determination result of the quality determination unit 52, and pays out to the non-defective product payout box 65 and the defective product payout box 66.

The abnormality determination unit 53 is configured to determine and report an abnormality in the knitting machine 70 based on the determination result of the quality determination unit 52.
Specifically, in the abnormality determination unit 53, as an abnormality of the knitting machine 70, a knitted fabric P having a weight exceeding the upper limit value of the set weight range is continuously dispensed a set number of times, and a knitting weight below the lower limit value of the set weight range is knitted. The state in which the woven fabric P is continuously paid out a set number of times, the state in which the knitted fabric P is not paid out for a certain period of time, and the like are determined by using the determination result of the quality determination unit 52 and the like. Then, the abnormality of the knitting machine 70 determined in this way is notified to the operator in real time by the lighting of the lamp arranged on the indicator 56, the alarm sound generated by the buzzer 57, and the like.
Further, the abnormality determination unit 53 can automatically stop the knitting machine 70 when the abnormality of the knitting machine 70 occurs continuously a predetermined number of times. Further, in the unmanned operation performed at night or the like, the knitting machine 70 can be automatically stopped at the first abnormality determination.
