Description

Doffing trolley capable of achieving accurate positioning

Technical Field

The utility model relates to a textile machinery technical field, more specifically relates to a can realize doffing dolly of accurate location.

Background

In the conventional doffing process, when a single spindle sends a full bobbin signal, a worker takes off the wound bobbin yarn from the support arm and puts the prepared empty bobbin back on the support arm. At present, automatic doffing trolleys are also provided, automatic equipment replaces manual doffing and manual doffing, unmanned management of workshops can be achieved, and working efficiency is improved. The conventional automatic doffing trolley is controlled by a control system to move in a guide rail, and after a signal of needing doffing is received, the doffing trolley moves to the lower part of a corresponding spindle, the common doffing trolley in the prior art is poor in positioning accuracy in the advancing process or needs manual matching for positioning, and some equipment with good positioning accuracy is complex in structure and high in cost.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a can realize doffing dolly of accurate location can realize the accurate location of secondary through the mechanical device cooperation.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a can realize doffing dolly of accurate location, is including installing the guide rail on the machine, sliding connection has the doffing dolly on the guide rail, the bottom equidistance of guide rail is provided with a plurality of V-arrangement pieces, be equipped with the location cylinder on the doffing dolly, the top of location cylinder be connected with V-arrangement piece complex V-arrangement fixture block, install the proximity switch that can detect the V-arrangement piece on the doffing dolly. The doffing trolley is provided with trolley rollers which are matched with the guide rails to slide, and on the equipment, a sensor for measuring the winding length of the spindle is arranged on each single spindle head. Once the metering length reaches the full spindle winding length, the sensor can send out a full spindle signal, and the automatic doffing trolley realizes position positioning through a high-precision encoder, and at the moment, the positioning is realized for one time.

When the proximity switch on the doffing trolley detects the V-shaped block on the guide rail, the doffing trolley continues to move until the proximity switch cannot detect the V-shaped block, and the position of the doffing trolley is set as a positioning origin, namely the center of the V-shaped block of the positioning cylinder is aligned with the edge of the V-shaped block on the guide rail. And (3) according to the compensation distance which is set in advance in the program, enabling the doffing trolley to move to the position where the center of the V-shaped fixture block of the positioning cylinder is aligned with the V-shaped block on the guide rail, such as the position 3 (b) in the figure 2. In the process, the stepping motor for controlling the movement of the doffing trolley is turned off, and the trolley can be easily moved left and right at the moment. The positioning cylinder extends out, the V-shaped block is clamped into the V-shaped block, the positioning cylinder drives the doffing trolley to move left and right to achieve accurate positioning at the position shown by 3 (a) in figure 2, and the repeated positioning accuracy is guaranteed within the range of 0.1 mm. The utility model discloses simple structure, positioning accuracy are good, can realize automatic positioning.

To sum up, the utility model discloses a method that sensor primary location and mechanical structure secondary location combined together realizes the accurate location of doffing dolly, and repeated positioning accuracy guarantees at 0.1mm within range, has improved the rate of accuracy and the high efficiency of automatic doffing link greatly. The method provides guarantee for unmanned management of the doffing link, greatly reduces the number of the using workers, and stably improves the product quality.

Description of the labeling: 1. a guide rail; 2. a V-shaped block; 3. a V-shaped clamping block; 4. positioning the air cylinder; 5. a proximity switch; 6. trolley rollers.

Detailed Description

The present invention will be further described with reference to fig. 1 to 3 with reference to a specific embodiment of a doffing cart capable of realizing accurate positioning.

The utility model provides a can realize doffing dolly of accurate location, is including installing guide rail 1 on the machine, sliding connection has the doffing dolly on guide rail 1, the bottom equidistance of guide rail 1 is provided with a plurality of V-arrangement pieces 2, be equipped with location cylinder 4 on the doffing dolly, the top of location cylinder 4 be connected with V-arrangement piece 2 complex V-arrangement fixture block 3, install proximity switch 5 that can detect V-arrangement piece 2 on the doffing dolly. And a trolley roller 6 which is matched with the guide rail 1 to slide is arranged on the doffing trolley, and a sensor for measuring the winding length of the spindle is arranged on each single spindle head on the device. Once the metering length reaches the full spindle winding length, the sensor can send out a full spindle signal, and the automatic doffing trolley realizes position positioning through a high-precision encoder, and at the moment, the positioning is realized for one time.

When the proximity switch 5 on the doffing trolley detects the V-shaped block 2 on the guide rail 1, the doffing trolley continues to move until the proximity switch 5 cannot detect the V-shaped block 2, and the position of the doffing trolley is set as a positioning origin at the moment, namely, the center of the V-shaped fixture block 3 of the positioning cylinder 4 is aligned with the edge of the V-shaped block 2 on the guide rail 1. According to the compensation distance which is set in advance in the program, the doffing trolley moves to the position where the center of the V-shaped fixture block 3 of the positioning cylinder 4 is aligned with the V-shaped block 2 on the guide rail 1, as shown in the position 3 (b) in figure 2. In the process, the stepping motor for controlling the movement of the doffing trolley is turned off, and the doffing trolley can be easily moved left and right at the moment.
