DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The present embodiment discloses a conveying assembly with a cloth roll turning function. The cloth roll conveying assembly 4 is used in conjunction with a seam head device 1 to convey a cloth roll 100 to be seamed. The input cloth roll 100 may be in the front and back positions. The cloth roll can be rotated and turned to ensure that the front and back positions of the cloth roll are consistent. Figure 1-Figure 9 Provide detailed explanation.

[0040] Reference Figure 1 , Figure 2 , Figure 3 As shown, it includes a cloth roll turning device 2, a cloth roll flipping device 5, a cloth roll conveyor belt 6 and a cloth roll storage trough 7, which are, from right to left, the cloth roll storage trough 7, the cloth roll conveyor belt 6, the cloth roll flipping device 5 and the cloth roll turning device 2, and the seam head device 1 is placed at the far right position.

[0041] The cloth roll storage trough 7 is used to store cloth rolls, and the cloth roll storage trough 7 is rotatably connected to the frame. By rotating and adjusting the cloth roll storage trough 7, the stored cloth rolls can be dumped onto the cloth roll conveyor belt 6, and then sequentially conveyed by the cloth roll conveyor belt 6. The cloth roll conveyor belt 6 is located at the cloth roll turning device 2 and is installed with the cloth roll storage trough 7, and can convey the cloth roll toward the cloth roll turning device 2.

[0042] The cloth roll turning device 5 is located between the cloth roll turning device 2 and the cloth roll conveyor belt 6 . The cloth roll turning device 5 can convey a single component, thereby preventing the cloth roll conveyor belt 6 from simultaneously inputting multiple cloth rolls into the cloth roll turning device 5 .

[0043] Reference Figure 4 As shown, the cloth roll turning device 5 includes a turning cylinder 51, which is rotatably connected to the frame, and the rotation axis of the turning cylinder 51 is parallel to the axis of the cloth roll being transported. A cloth storage gap 52 is provided on the outer periphery of the turning cylinder 51, and the cloth storage gap 52 is used to store a single cloth roll, and the cloth roll can be transported to the cloth roll turning device 5 by rotating. When it is necessary to transport a cloth roll, the turning cylinder 51 rotates, and the cloth storage gap 52 will rotate to the side facing the cloth roll conveyor belt 6, and the cloth roll at the end of the cloth roll conveyor belt 6 can enter the cloth storage gap 52. Then, the turning cylinder 51 rotates counterclockwise, and the cloth storage gap 52 will carry the cloth roll to produce a turning displacement until the cloth roll falls off from the cloth storage gap 52, and the cloth roll enters the cloth roll turning device 2.

[0044] The cloth roll 100 originally input into the cloth roll storage tank 7 has different winding directions, and when the cloth roll is connected at the seam end, the front and back of the cloth roll need to be kept consistent. The cloth roll turning device 2 can turn the cloth roll horizontally, and then adjust the winding directions of each component to be consistent.

[0045] Reference Figure 5 As shown, the cloth roll turning device 2 includes a cloth roll temporary storage platform 23, and the cloth roll temporary storage platform 23 is provided with three groups of temporary storage seats 24, and the three groups of temporary storage seats 24 are arranged along the axial direction of the cloth roll. The cloth roll can be supported by the temporary storage seats 24, and a recessed position is formed on the upper part of the temporary storage seat 24, and the recessed position can limit the cloth roll, and only one group of cloth rolls can be easily passed.

[0046] Specifically, the temporary storage seat 24 includes a support frame 241 and a plurality of support rollers 242. The support frame 241 plays a supporting role. Each support roller 242 is rotatably connected to the support frame 241. The axes of the plurality of support rollers 242 are parallel to the axis direction of the cloth roll. The middle support roller 242 is located at a lower position, and a concave space for accommodating the cloth roll is formed on the upper part of the plurality of support rollers 242. The cloth roll 100 can be sunken into the concave space, and through the rotation of the support rollers 242, the cloth roll 100 can be adaptively deflected and adjusted.

[0047] In this embodiment, the temporary storage seats 24 are three groups, which are divided into two groups of fixed temporary storage seats 244 and one group of movable temporary storage seats 243. The fixed temporary storage seats 244 are fixedly mounted on the frame, and the movable temporary storage seats 243 are located in the middle of the fixed temporary storage seats 244. The position of the movable temporary storage seats 243 corresponds to the middle position of the cloth.

[0048] The cloth roll turning device 2 also includes a lifting device 8 and a rotating device 9, and the movable temporary storage seat 243 is installed through the lifting device 8 and the rotating device 9, wherein the movable temporary storage seat 243 is raised and lowered by the lifting device 8 and rotated and adjusted by the rotating device 9, so that the cloth roll supported by the upper part of the movable temporary storage seat 243 can be lifted up, and then rotated and turned to adjust the direction of the cloth roll.

[0049] The movable temporary storage seat 243 has an upward and downward movable stroke. The movable temporary storage seat 243 is at the highest position formed. The rotation position of the cloth roll supported by the upper part of the movable temporary storage seat 24 can be avoided to avoid interference between the cloth roll and other components during the rotation process, ensuring that the cloth roll can rotate smoothly. The lowest position of the movable temporary storage seat 24 is not higher than the fixed temporary storage seat 244. Generally, when the movable temporary storage seat 24 is at the lowest position, the heights of the three groups of temporary storage seats 24 remain consistent, and the three groups of temporary storage seats 24 jointly support multiple cloth rolls.

[0050] In order to maintain the stability of the cloth roll in the lifted state, the support roller 242 of the movable temporary storage seat 24 has a certain length, which is greater than one-third of the width of the cloth roll, so that the cloth roll can be supported only by the movable temporary storage seat 24. In addition, the movable temporary storage seat 24 can support the components. In the supported state, the cloth roll is partially embedded in the recessed position on the upper side of the movable temporary storage seat 24, which can maintain the stability of the cloth roll without the need for other structures to stabilize the components.

[0051] The movable temporary storage seat 243 has a rotational travel, and the rotational travel of the movable temporary storage seat 243 is approximately 180°, which can realize the cloth roll to rotate 180° in the horizontal direction. In addition, since the temporary storage seat 24 is equipped with a support roller 242, the support roller 242 can be rotated. In the temporary storage seat 24, the cloth roll can be tilted and deflected by rotating multiple support rollers 242. Even if there is a small deviation in the rotation angle of the movable temporary storage seat 243, during the descent process, the two ends of the cloth roll can fall into the fixed temporary storage seats 244 on both sides respectively, and the rotation of the support roller 242 can cause the cloth roll to have a small deflection, so that the cloth roll can be automatically adjusted.

[0052] Reference Figure 7 , Figure 8 As shown, the lifting device 8 includes a lower seat 81, an upper seat 83, a transmission structure 82 and a driver 84. The lower seat 81 is located at the bottom of the lifting device 8 as a support, and the upper seat 83 is located on the upper part of the lower seat 81. The transmission structure 82 is located between the upper seat 83 and the lower seat 81, and can realize lifting transmission; the transmission structure 82 can specifically adopt a scissor lift structure, and the upper and lower ends of the transmission structure 82 can be lifted and lowered by rotating the scissors.

[0053] Specifically, the scissors-type lifting structure has a lower fixed end 821, a lower movable end 822, an upper fixed end 823 and an upper movable end 824, wherein the lower fixed end 821 is rotatably connected to the lower seat 81, the lower movable end 822 is rotatably connected to the lower slider 825, and the lower slider 825 is slidably connected to the lower seat 81; the upper fixed end 823 is rotatably connected to the upper seat 83, the upper movable end 824 is rotatably connected to the upper slider 826, and the upper slider 826 is slidably connected to the upper seat 83.

[0054] The driver 84 is a linear driver, and its driving end is connected to the lower slider 825. The driver 84 can drive the lower slider 825 to slide. During the sliding process, the lower fixed end 821 and the lower movable end 822 of the scissor lift structure will approach each other, so that the upper side of the scissor lift structure can be adjusted up and down. The upper slider 826 can slide adaptively as the scissor lift structure rises and falls.

[0055] Reference Figure 7 , Figure 8 , Fig. 9 As shown, the rotating device 9 includes a fixed seat 91, a rotating seat 92 and a rotating drive mechanism 93. The fixed seat 91 is fixedly mounted on the upper seat 83, and the rotating seat 92 is rotatably connected to the fixed seat 91 through a shaft structure 94. The axis of the shaft structure 94 is arranged in the up-down direction. The shaft structure 94 is a combination structure of a rotating shaft and a thrust bearing, which can smoothly realize rotation and stably support the weight of the cloth roll.

[0056] The rotary drive mechanism 93 can drive the rotating seat 92 to rotate and adjust, so that the cloth roll can be turned around by 180 degrees, thereby realizing the cloth roll turning around.

[0057] Reference Fig. 9 As shown, the rotary drive mechanism 93 is a gear rack structure, including a gear 931, a rack 932 and a cylinder 933. The two sets of gear rack structures drive the rotating seat 92 at the same time, so that the rotating seat 92 and the cloth roll can be deflected at the required angle to achieve the U-turn of the cloth roll.

[0058] Among them, the gear 931 is fixedly mounted on the shaft structure 94 of the rotating seat 92, and the rack 932 meshes with the gear 931 and is reciprocated by the cylinder 933. The reciprocating stroke of the cylinder 933 is the active stroke of the rack 932, and the gear 931 will also reciprocate and rotate within a certain rotation range, which just corresponds to the forward and reverse positions of the cloth roll.

[0059] In order to maintain the activity stability of the rack 932 , a guide slide seat 934 may be installed at the lower portion of the fixed seat 91 , and the guide slide seat 934 may be used to guide the rack 932 in sliding manner, thereby maintaining the sliding stability of the rack 932 .

[0060] Further, refer to Figure 5 , Figure 6 As shown, the cloth roll temporary storage table 23 is provided with a cloth pushing rod 25, which is located between two adjacent groups of temporary storage seats 24. The cloth pushing rod 25 can be driven by a driver to push the cloth roll, and can push the cloth roll out of the temporary storage seat 24 and enter the subsequent conveying structure.

[0061] Specifically, one end of the cloth pushing rod 25 is rotatably connected to the frame, and the other end can move between the two sets of temporary storage seats 24. The cloth pushing rod 25 can be pushed up and down by the cylinder. During the upward deflection of the cloth pushing rod 25, part of the cloth pushing rod 25 will be pushed out to the upper side of the temporary storage seat 24, and the cloth roll can be pushed backward to achieve the transfer of the cloth roll.

[0062] This embodiment also discloses a seaming machine, including a seaming device 1 and a cloth roll conveying assembly in the above embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 Detailed description is given below.

[0063] The end-sewing device 1 is used to connect the ends of two rolls of cloth by sewing, so that the cloth can be spliced ​​to form a longer length to adapt to the subsequent processing of the cloth. The specific structure of the end-sewing device 1 is prior art and will not be described again.

[0064] The sewing device 1 is provided with a cloth loading position 11. During the sewing process, the cloth to be connected by the sewing head is first transported to the cloth loading position 11 of the sewing device 1. Then, the mechanism in the sewing device 1 operates to process the parts to be sewn to realize the sewing operation.

[0065] The cloth loading position 11 serves to receive the cloth roll for the seam head. The seam head device 1 and the cloth roll conveying assembly 4 are respectively located on both sides of the cloth loading position 11, and the cloth roll 100 input from the cloth roll conveying assembly 4 is input into the seam head device 1 through the cloth loading position 11.

[0066] Reference Figure 1 , Figure 4 As shown, the cloth roll turning device 2 also includes an inclined guide platform 21 and a movable guide platform 22. The inclined guide platform 21 is located on the side of the cloth roll temporary storage platform 23 close to the cloth loading position 11. Generally, the inclined guide platform 21 can be an inwardly concave arc structure and gradually descends toward the cloth loading position 11.

[0067] A gap 3 for people to pass through is formed between the inclined guide platform 21 and the cloth loading position 11. Since there is a gap between the two, the cloth needs to be guided at the gap 3 by the movable movable guide platform 22. A sliding frame 221 is provided at the lower part of the movable guide platform 22. The movable guide platform 22 can slide and adjust between the inclined guide platform 21 and the cloth loading position 11, and the height of the movable guide platform 22 is higher than the table height of the cloth loading position 11, but lower than the height of the lowest point of the inclined guide platform 21, so that the cloth roll can smoothly roll from the inclined guide platform 21 to the cloth loading position 11 by its own weight during the transmission process.

[0068] The movable guide platform 22 is driven by a linear push rod 222 to achieve sliding adjustment. Since the height of the movable guide platform 22 is lower than the inclined guide platform 21, and a space is reserved at the lower side of the inclined guide platform 21, the movable guide platform 22 can slide into the lower side of the inclined guide platform 21 when not in use, so as to store the movable guide platform 22, and the operator can move it at the interval 3, so as to facilitate the operation of the seam head device 1.

[0069] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
