Abstract

PURPOSE:To provide the title apparatus so designed that the moving speed of a carriage and the actuation speed of a hooking machine head are ensured to be changeable according to the angle of the carriage against X-axis, thereby beating yarns at invariably definite denseness even if the head on the hooking machine moves in any direction against the X-axis. CONSTITUTION:In a hooking machine so designed that a carriage 6 movable in the XY-axes directions above a cloth 2 stretched on a frame 4 is fitted with a head 7 for putting a needle 11 to vertical motion through the rotation of a servomotor 14, the carriage 6 is ensured to be moved in the X-axis or Y-axis direction, and when this carriage is to be moved in the direction at a given angle against the X-axis, its moving speed is made controllable according to this angle, whereas the rotational speed of the servomotor 14 is also made controllable.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to automatic hook drag weaving equipment.

[Conventional technology]

In general, an automatic hook drag weaving machine uses an f! :It was constructed by attaching a hook device to a main body that was movable in the x-axis and y-axis directions.

[The problem that the invention attempts to solve]

By the way, in conventional hook machines, the vertical movement of the needle is controlled only by operating a switch on the motor, so the motor of the hook machine always rotates at a constant rotation speed during weaving. It was. For this reason, even when the speed of movement increases when the main body changes direction, the weaving operation has to continue at a constant speed, resulting in more thread than necessary being inserted at the required intervals, resulting in a dense weave. .

Therefore, in the past, attempts were made to obtain good weaving by controlling the advancing speed of the main body and giving a command to speed up the weaving machine so that it would proceed at a speed corresponding to the weaving speed of the 7-tsuku machine when changing direction. However, even if a speed-up command is issued at an early stage, the response is slow due to the large inertia of the main body, and a situation arises in which the speed required to obtain good textile work is not reached. It was difficult to eliminate the dense fiber state.

Moreover, if you set K so that a command that speeds up the main body's speed when changing direction at a certain angle or less is set, it will automatically change direction at an angle that does not reduce the speed of the main body (for example, Even when drawing large polygons, the speed of movement of the main body was increased, and the hook machine, which weaved at a constant speed, sometimes resulted in coarse weaving.

In this way, with the method of controlling the movement by giving commands to the main body with large inertia, there are cases where the desired command is not followed due to the influence of inertia, or there is a contradiction that the movement speed of the main body increases when unnecessary. This was inconvenient for performing the desired weaving work.

Therefore, the present invention attempts to perform the desired weaving work by controlling the hook machine in addition to controlling the main body.

[Means for solving problems]

In order to achieve the above object, the present invention is provided so as to be movable in the X-ray direction and the Y-ray direction above the raw cloth stretched on the frame,
A hook machine equipped with a main body whose traveling speed is adjusted when the direction of travel changes below a certain angle, and a motor that is attached to the main body and whose rotational speed is changed according to changes in the speed of travel when the main body changes the direction of travel. It consists of

Further, it is preferable that the hook device is detachable and replaceable with respect to the motor attached to the main body.

[For production]

The motor of the hook machine is a servo motor, an inverter controlled motor, or a similar controlled motor. The balance between the traveling speed of the main body and the vertical movement speed of the needle of the hook machine is determined based on the angle at which the main body changes direction and the distance traveled. For example, as shown in Fig. 4, when the main body changes direction by 45 degrees at point B and travels 15Il1l to point C, the program shown in Fig. 5 calculates θ=135 (however, θ is Angle obtained by subtracting the turning angle from the direction of travel), z = 1
5 (where L is the distance traveled after changing direction), and since 100≦θ and 0xt≦20,
At point A, which is 10 minutes before point B, the rotation of the motor of the hook machine is reduced to 50% speed, and this state is maintained until point C is reached. Next, when turning 165R at point C and proceeding 60 seconds to point D, it is expressed as θ=45 1=50, not 100≦θ, but 20≦θ<100, and t>15 Therefore, since 15≦t is not O, the motor of the hook machine is restored to 100% rotation at point C.

At this time, in a slight change in direction as represented by θ<20>, there is no reduction in the traveling speed of the main body, so there is no need to slow down the rotation of the motor of the hook machine.

In addition, even if a direction change is made at a steep angle, the decrease in the speed of the main unit will be small if the next distance to travel is long. All you have to do is work at about 701.
