Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of knitting machines, especially relates to a knitting and sewing integrated hosiery machine. BACKGROUND

[0002] The knitting and sewing integrated hosiery machine is the mainstream intelligent hosiery machine at present, which is a combination of a knitting machine and a sewing machine and automatically performs a sewing process after the completion of knitting. The most common technical solution is recorded in Chinese patents CN200980108857.2, CN200980108858.7, CN200980108882.0 and CN200980120878.6. After the completion of knitting, a transfer mechanism hooks the last row of loops of the knitted socks, and then the socks are taken out of the needle cylinder of the knitting machine and transferred to the sewing machine. The sewing machine has an upper assembly and a lower assembly, and the transfer mechanism with the hooked socks moves between the upper assembly and the lower assembly, so that the socks first enter the sock turning tube in the lower assembly, and then the sock turning tube moves up to the upper assembly. In this process, the socks are turned over and come to the upper assembly with the sock turning tube, and then the loops hooked on the transfer mechanism are sewn. In the above process, if the socks are too long, even if the transfer mechanism has been moved into position, a part of the socks may still be left in the needle cylinder and cannot smoothly enter the sock turning tube.

[0003] The applicant has applied for a utility model patent named "a straight sending type sock conveyor", patent number 202220447031.1, which is installed on an integrated knitting and sewing hosiery machine. The integrated knitting and sewing hosiery machine includes a hosiery machine, a sock sewing machine, a sock suction cylinder, and a picking assembly. The picking assembly can pick up one end of the sock in the needle cylinder assembly of the sock sewing machine to the sewing tooth disc of the sock sewing machine. The sewing tooth disc and the needle cylinder assembly form a sock conveying path. The sock suction cylinder has a sock suction state located directly below the sock conveying path. The sock conveyor is installed between the hosiery machine and the sock sewing machine and includes a lifting conveying assembly. The lifting conveying assembly has a working position located directly above the sock suction cylinder in the sock suction state. The lifting conveying assembly includes a lifting rod and a lifting head. The lifting head is installed on the lifting end of the lifting rod and is used to convey the sock in the sock conveying path downward into the sock suction cylinder in the sock suction state when the lifting head is in the working position. The purpose of this technical solution is to move the lifting rod downward to push the sock into the sock suction cylinder, i.e., the sock tube, when one end of the sock is hooked on the picking assembly, i.e., the transfer mechanism, and the other end is still in the needle cylinder. The defect of this prior art is that the lifting rod necessarily needs a fixed mounting seat. The mounting seat is installed on the transfer path between the hosiery machine and the sock sewing machine. There are not many bases available for installation in this space, and the position is relatively low. At the same time, the mounting seat of the lifting rod cannot be too high above the base because it may interfere with the movement of the transfer mechanism. Therefore, the extension distance of the lifting rod is limited, i.e., the lifting rod only has a small stroke, and it may still not be able to completely pull the sock out of the needle cylinder and push it into the sock tube. SUMMARY

[0004] The utility model discloses a kind of knitting and sewing integrated hosiery machines, which can be applied to longer socks.

[0005] The utility model discloses a kind of knitting and sewing integrated hosiery machines, which can be applied to longer socks.

[0006] Further, the lower assembly has a driving mechanism that moves a certain distance in the horizontal direction, so that the extension line of the lifting rod falls into the sock suction tube in the lower assembly.

[0007] The lower assembly has a driving mechanism that rotates a certain angle in the vertical direction, and the lifting rod assembly forms the same angle with the axis of the upper assembly, so that the extension line of the lifting rod falls into the sock suction tube in the lower assembly.

[0008] The two further technical solutions can be used independently or in combination.

[0009] There are two main ways to make the knitted socks smoothly enter the sock suction tube of the lower assembly. One is to translate the lower assembly in the horizontal direction to approach the hosiery machine, and the other is to rotate the lower assembly in the axial direction to increase the opening cross-sectional area towards the hosiery machine. The utility model makes targeted design for the two cases.

[0010] In some machines, the sock suction tube can reciprocate between the upper assembly and the lower assembly, and is connected to the upper assembly or the lower assembly respectively. During the upward movement of the sock suction tube, the socks are turned to wrap around the sock suction tube with the inner surface facing outward, and during the process of removing the socks, the socks are turned again with the outer surface facing outward, which is the scheme mentioned in the background section. At this time, the sock suction tube can also be called a sock turning tube. Such a machine is a weaving, sewing and turning integrated machine. In some other machines, the sock suction tube is always connected to the lower assembly and does not move upward. The upper assembly has other tubular components to accommodate the sewn socks and remove the socks after sewing is completed. Such a machine is a weaving and sewing integrated machine but does not perform sock turning. Obviously, there is no difference between the two machines in the process of transferring the socks from the hosiery process to the sock sewing process. The utility model can be applied to both machines.

[0011] The technical effect of the utility model is embodied in two aspects. One is that the lifting rod assembly is installed on the upper assembly of the sock sewing machine, which is farthest from the hosiery machine, i.e. the space between the hosiery machine and the sock sewing machine can be utilized to the maximum extent. The other is that the side of the upper assembly facing the hosiery machine is empty. There is no object in this space or no object that needs to pass through this space. Therefore, the lifting rod assembly can be made longer, so that the lifting rod also has a longer stroke, which is more conducive to the lifting rod to penetrate into the sock suction tube, thereby processing longer socks. BRIEF DESCRIPTION OF DRAWINGS

[0012] Figures 1 to 3 is a schematic diagram of the working process of the utility model. DETAILED DESCRIPTION

[0013] Referring to the drawings. Some technical features of the present embodiment are prior art, so the drawings and embodiments only describe the key parts in a brief schematic diagram, and the rest of the related content can be referred to the prior art literature mentioned in the background section.

[0014] The present embodiment includes a hosiery machine 1 and a transfer mechanism 2, Figure 1 The state shown is that the hosiery has been completed, and the transfer mechanism hooks the last row of loops of the sock 00 and pulls it out of the needle cylinder 11 of the hosiery machine. At this time, the transfer mechanism 2 has moved between the upper assembly and the lower assembly of the sock sewing machine.

[0015] The sock sewing machine includes an upper component 3 and a lower component 4. The lower component 4 is mounted on a track 41 and can translate along the track 41. As can be seen in the figure, the track 41 is inclined, so the translation of the lower component 4 is also oblique and can be decomposed into horizontal and vertical components. Figure 1 In the state shown, the lower component has moved a certain distance toward the direction of the sock knitting machine.

[0016] On the side of the upper component 3 facing the knitting machine, a lifting rod assembly 6 is installed. The lifting rod assembly 6 contains a lifting rod 61. In fact, the lifting rod assembly is constructed like a cylinder piston, and the lifting rod 61 is the piston. Figure 2 In the indicated state, the lifting rod 61 extends downwards, pushing the sock 00 into the suction tube 5 of the lower assembly. The sock, pushed and pulled by the lifting rod, is completely pulled out of the syringe 11.

[0017] exist Figure 3 In the state shown, under the pushing and pulling of the lifting rod and the negative pressure inside the suction tube, the sock 00 has been completely inserted into the suction tube 5; at the same time, the lower component 4 returns to its original position along the track 41, that is, the position corresponding to the upper component 3, ready to proceed to the next process.
