Description

Technical Field

[0001] The invention belongs to the technical field of knitting, and relates to an auxiliary device for a warp knitting machine, and in particular to a power-assisted trolley for workers in a warp knitting machine workshop. Background Art

[0002] The loom operator is a type of operator in the textile industry who operates the loom. Their service items mainly include checking whether the machine has any abnormal noise, whether the yarn paths are unobstructed, whether the tension is constant, whether the fabric surface and winding are normal, and solving any possible fabric problems that may arise during the operation of the warp knitting machine. It is crucial to maintain the normal operation of the warp knitting machine.

[0003] Under normal circumstances, warp knitting machines are placed in workshops, and operators need to constantly shuttle between the machines they manage for inspection. When receiving alarm messages of warp knitting machine failures such as yarn breakage, they need to rush to the faulty warp knitting machine as soon as possible and deal with the failure in time to ensure the normal production of the warp knitting machine in the workshop. In a large weaving workshop, more than 100 warp knitting machines need to be set up to form a large cluster of warp knitting machines to save floor space. Therefore, multiple operators need to be equipped at the same time, and the labor cost is relatively high. In addition, under the existing technology, operators still have the following shortcomings when managing and controlling warp knitting machines:

[0004] 1. When the operator controls the warp knitting machine, he needs to constantly shuttle between the machines he controls, which causes the operator to walk more than 30,000 steps a day. This causes high fatigue intensity, and the operator is easily fatigued, which reduces work efficiency.

[0005] 2. The existing warp knitting machines are very stable, and one operator can operate up to 10 machines. However, in order to ensure the stability of the machines and not exceed the fatigue resistance of the personnel, each operator can only effectively control 3 to 4 warp knitting machines at the same time in reality, which restricts the further reduction of labor costs and the further improvement of single-person production capacity;

[0006] 3. Existing weaving workshops are still dominated by labor-intensive and skill-based work modes, and cannot be transformed into intelligent automation. Summary of the invention

[0007] The present invention aims to solve the deficiencies in the prior art and provides a power-assisted trolley for a warp knitting machine worker in a warp knitting machine workshop, which facilitates the worker's control over the machine, reduces the worker's physical exertion, and effectively improves production efficiency.

[0029] In order to enable ordinary technicians in this field to better understand the technical solution of the present invention, the following Figure 1-8 The technical solution of the present invention is further described with embodiments.

[0030] Example 1

[0031] Actual statistical data show that when a warp knitting worker manages four warp knitting machines, the number of steps he walks every day will exceed 30,000, which is completely beyond the fatigue limit of the human body. In order to solve the problems of high labor intensity of warp knitting workers and limited number of warp knitting machines monitored in the prior art, and to further improve production efficiency, the present invention designs a power-assisted trolley for warp knitting workers in a warp knitting machine workshop, several warp knitting machines 1 are arranged longitudinally in the workshop, and an annular tread guide rail 2 is laid on the periphery of the warp knitting machine 1, the tread guide rail 2 includes two inner and outer moving rails 7 and a middle tread groove 8, and the power-assisted trolley 3 is placed above the tread guide rail 2, and the power-assisted trolley 3 includes a translation trolley 4, a lifting mechanism 5 and a seat transverse movement mechanism 6 from bottom to top.

[0032] The translation trolley 4 includes a frame 41, a roller 42 and a servo motor 43. The roller 42 is installed at the four corners of the frame 41 through a pin shaft and is placed above the moving track 7 on the corresponding side. The servo motor 43 is installed on the inner side of the frame 41 and connected to the roller 42 through a pin shaft. A step plate 44 is provided on the side of the frame 41 close to the warp knitting machine 1, and the step plate 44 is placed on the step plate groove 8.

[0033] The lifting mechanism 5 includes, from top to bottom, a flat plate 51, two groups of lifting scissor rods 52 arranged inside and outside, and a lifting servo electric cylinder 53. Each group of lifting scissor rods 52 includes two rod plates, and the two rod plates are movably connected by a pin shaft to form a scissor shape. The middle parts of the two groups of lifting scissor rods 52 are built into a lifting structure through a lifting center axis 54. The upper ends of the rod plates that constitute the lifting scissor rods 52 are connected to the bottom of the flat plate 51 through a lifting angle seat 55. The bottom end of one of the rod plates is connected to the frame 41 through the lifting angle seat 55, and the bottom end of the other rod plate is installed with a lifting roller 56. The lifting rollers 56 of the two groups of lifting scissor rods 52 are connected by a pin shaft 57. The lifting servo electric cylinder 53 is installed on the frame 41. The output end of the lifting servo electric cylinder 53 is connected to a lifting rod 58, and the other end of the lifting rod 58 is connected to a connecting sleeve 59 on the pin shaft 57.

[0034] The seat transverse movement mechanism 6 includes a seat 61 and a fixed transverse movement slot plate 62 which is arranged on both sides of the bottom of the seat 61 and fixedly connected to the top of the flat plate 51. A transverse movement slot with closed ends is provided above the fixed transverse movement slot plate 62. A sliding block 63 is provided in the transverse movement slot. A transverse movement plate 64 is fixedly connected above the sliding block 63. The sliding block 63 is controlled by a transverse movement electric cylinder 65 to move along the transverse movement slot.

[0035] When the power-assisted trolley moves laterally on the track, in order to enhance the protection of the worker's body, a protection shed 9 is provided on the outside of the power-assisted trolley 3 , and a protection baffle extending toward the direction of the warp knitting machine 1 is provided on the top of the protection shed 9 .

[0036] Protective shell plates are provided on the outside of the translation trolley 4, the lifting mechanism 5 and the seat transverse movement mechanism 6. On the one hand, they play a role in dust prevention. On the other hand, they can also prevent the clothes of the car stopper or the yarn in the workshop from being hooked on the equipment when the mechanical structure is exposed, causing damage to the equipment or accidental injury to the operator.

[0037] The specific operation process is as follows: when the stopper sits in the power-assisted trolley 3 to work, he mainly guides and arranges the yarn of the warp knitting machine; when the stopper stands in the resistance trolley 3, his head extends toward the warp knitting machine and his hands also extend forward. This is the moment to deal with the yarn breakage of the warp knitting machine. The lifting servo electric cylinder 53 in the lifting mechanism 5 will push the lifting rod 58 to horizontally pull the connecting sleeve 59 on the pin shaft 57 connected to the lifting roller 56, so that the lifting structure formed by the lifting scissor rod 52 lifts the flat plate 51 up, and at the same time, the flat plate The transverse electric cylinder 65 on 51 starts to control the transverse plate 64 to move toward the warp knitting machine 1, thereby driving the seat 61 installed on the transverse electric cylinder 64 to move toward the warp knitting machine 1, forming a seat support for the car stopper. When dealing with the yarn breakage fault in the loop, the power-assisted trolley 3 is not allowed to move laterally along the step plate guide rail 2. When the yarn breakage in the loop is dealt with, the car stopper sits down, and the transverse movement mechanism 6 and the lifting mechanism 5 of the seat automatically return to their original state. After the car stopper sits in the corresponding position, the power-assisted trolley 3 is allowed to move laterally.

[0038] When a fault alarm occurs in any warp knitting machine 1 in the longitudinal direction, the power-assisted trolley 3 can quickly respond to the corresponding faulty machine position along the tread plate guide rail 2 under the drive of the servo motor 43, saving the physical strength of the machine stopper, so that the number of machines controlled by the machine stopper can be increased from four to ten, thereby saving labor costs and improving production efficiency.

[0039] Example 2

[0040] The difference between Example 2 and Example 1 is that the lifting and lowering of the lifting mechanism 5 is not achieved by the cooperation of the lifting scissor rod 52 and the lifting servo electric cylinder 53. The lifting mechanism 5 disclosed in this embodiment mainly includes a flat plate 51 and a push cylinder arranged at the bottom thereof. The bottom of the flat plate 51 is connected to the movable shaft at the top of the push cylinder, and the push cylinder is fixed to the frame 41. When the seat 61 needs to be raised, starting the push cylinder can directly drive the seat 61 arranged on the flat plate 51 to rise. This lifting method is faster and more convenient.

[0041] The above shows and describes the basic principles, main features and advantages of the present invention. However, the above is only a specific embodiment of the present invention, and the technical features of the present invention are not limited thereto. Any other implementation methods derived by any technician in the field without departing from the technical solution of the present invention should be included in the patent scope of the present invention.
