[0073] The present application provides a tongue plate mechanism for shoulder loop folding, and a cloth piece folding device including the tongue plate mechanism for shoulder loop folding. Figure 1 and Figure 2 As shown, the fabric folding device is used to automatically fold and sew the upper fabric 100 and the lower fabric 200 that form the shoulder loops.

[0074] like Figure 3 and Figure 4As shown, the tongue plate mechanism for folding the shoulder loop involved in the present application includes a fixed mounting plate 10, and an upper tongue plate unit 20 and a lower tongue plate unit 30 both mounted on the mounting plate 10. The upper tongue plate unit 20 includes an upper tongue plate 21 for shaping the upper cloth piece 100 of the shoulder loop, and the lower tongue plate unit 30 includes a lower tongue plate 31 for shaping the lower cloth piece 200 of the shoulder loop. For ease of description, in the following embodiments, the length direction of the shoulder loop is defined as the front-to-back direction, the width direction of the shoulder loop is defined as the left-to-right direction, and the thickness direction of the shoulder loop is defined as the up-down direction. Based on this, Figure 4 In the view shown, the left side and right side of the paper are the front direction and the rear direction respectively, the upper side and the lower side of the paper are the upper direction and the lower direction respectively, and the front side and the back side of the paper are the right direction and the left direction respectively.

[0075] In particular, if Figure 3 and Figure 4 As shown, the tongue plate mechanism for shoulder strap folding involved in the present application also includes a lifting drive source and a lateral shift drive source 22. At least one of the upper tongue plate 21 and the lower tongue plate 31 is installed on the mounting plate 10 so as to be movable up and down, and the lifting drive source is connected to the upper tongue plate 21 and / or the lower tongue plate 31 in a transmission connection to drive the upper tongue plate 21 and / or the lower tongue plate 31 to move up and down. At least one of the upper tongue plate 21 and the lower tongue plate 31 is installed on the mounting plate 10 so as to be movable left and right along the width direction of the upper fabric piece 100 and the lower fabric piece 200, and the lateral shift drive source 22 is connected to the upper tongue plate 21 and / or the lower tongue plate 31 in a transmission connection to drive the upper tongue plate 21 and / or the lower tongue plate 31 to move left and right.

[0076] When the upper fabric piece 100 and the lower fabric piece 200 of the buckle shoulder loop are aligned, the state of the upper fabric piece 100 and the lower fabric piece 200 is as follows: Figure 1 and Figure 2 As shown, the upper fabric piece 100 is pressed on the upper tongue plate 21, and the upper straight edge on the left side, the upper straight edge on the right side, and the upper right bevel edge of the upper fabric piece 100 are completely folded under the upper tongue plate 21; the lower fabric piece 200 is pressed under the lower tongue plate 31, and the lower straight edge on the left side, the lower straight edge on the right side, and the lower bevel edge on the front left side of the lower fabric piece 200 are completely folded above the lower tongue plate 31, and the upper tongue plate 21 is located directly above the lower tongue plate 31. The upper left bevel edge 101 of the upper fabric piece 100 that is not folded at the front end is the buckle edge of the upper fabric piece 100, and the lower right bevel edge 201 of the lower fabric piece 200 that is not folded at the front end is the buckle edge of the lower fabric piece 200.

[0077] The buckling process is as follows: the push plate in the cloth folding device moves toward the upper left end upper bevel 101 of the upper cloth 100, and folds the upper left end upper bevel 101 of the upper cloth 100 slightly inward; at the same time, another push plate in the cloth folding device moves toward the lower right end lower bevel 201 of the lower cloth 200, and folds the lower right end lower bevel 201 of the lower cloth 200 slightly inward. After that, the side shift drive source 22 is activated to drive the upper tongue plate 21 to move left and / or the lower tongue plate 31 to move right, so that the upper tongue plate 21 and the lower tongue plate 31 are staggered in the left-right direction, and the upper cloth 100 and the lower cloth 200 are staggered in the left-right direction. After that, the lifting drive source is activated to drive the upper tongue plate 21 to move down and / or the lower tongue plate 31 to move up, so that the upper tongue plate 21 and the lower tongue plate 31 are close to each other in the up-down direction, and the upper cloth 100 and the lower cloth 200 are close to each other in the up-down direction. Afterwards, the lateral drive source 22 is reset, driving the upper tongue plate 21 to move rightward and / or the lower tongue plate 31 to move leftward and rightward, so that the upper tongue plate 21 and the lower tongue plate 31 are reset to a state of being directly facing each other in the left-right direction. In this process, the upper left upper bevel 101 of the upper fabric piece 100 and the lower right lower bevel 201 of the lower fabric piece 200 partially overlap, completing the pre-fastening. Afterwards, the push plate in the fabric folding device completely folds the lower right lower bevel 201 of the lower fabric piece 200 inward, and the push plate in the fabric folding device completely folds the upper left upper bevel 101 of the upper fabric piece 100 inward, so that the upper left upper bevel 101 of the upper fabric piece 100 completely enters the buckling edge of the lower fabric piece 200, and the upper fabric piece 100 and the lower fabric piece 200 are combined to complete the buckling.

[0078] Therefore, the present application can reliably align the upper bevel 101 at the front left end of the upper fabric piece 100 and the lower bevel 201 at the front right end of the lower fabric piece 200 through the up and down movement and left and right movement of the upper tongue plate 21 and / or the lower tongue plate 31, effectively realizing the automatic folding and interlocking of the upper fabric piece 100 and the lower fabric piece 200 during the automatic folding and sewing process of the shoulder loops, and reliably ensuring the quality of the automated sewing of the shoulder loops.

[0079] Preferably, in this embodiment, the upper tongue plate 21 and the lower tongue plate 31 can both move up and down, and the upper tongue plate 21 can also move left and right at the same time, but the lower tongue plate 31 cannot move left and right. Therefore, the side shift drive source 22 is connected to the upper tongue plate 21 in a transmission manner, and only drives the upper tongue plate 21 to move left and right.

[0080] Furthermore, if Figure 3 and Figure 4As shown, the tongue plate mechanism for shoulder strap folding also includes a first longitudinal drive source 41, a first longitudinal movable seat 42, a first longitudinal connection block 43, and a first linear guide assembly 44 extending forward and backward. The first longitudinal movable seat 42 is installed on the top surface of the mounting plate 10 so as to be movable forward and backward through the first linear guide assembly 44. The first longitudinal drive source 41 is a fixedly arranged cylinder, and the two ends of the first longitudinal connection block 43 are respectively fixedly connected to the cylinder piston rod of the first longitudinal drive source 41 and the first longitudinal movable seat 42, that is, the first longitudinal drive source 41 is transmission-connected to the first longitudinal movable seat 42 through the first longitudinal connection block 43, so as to drive the first longitudinal movable seat 42 to move forward and backward; the upper tongue plate unit 20, the lower tongue plate unit 30, the lifting drive source and the lateral drive source 22 are all installed on the first longitudinal movable seat 42. In this way, after the upper piece of cloth 100 and the lower piece of cloth 200 are folded, the cylinder piston rod of the first longitudinal drive source 41 extends backward, driving the first longitudinal movable seat 42 to move backward, and the upper tongue plate unit 20, the lower tongue plate unit 30, the lifting drive source and the side shift drive source 22 move backward together with the first longitudinal movable seat 42, driving the upper tongue plate 21 and the lower tongue plate 31 to move backward, the upper tongue plate 21 withdraws backward from the folded upper piece of cloth 100, and the lower tongue plate 31 withdraws backward from the folded lower piece of cloth 200, to facilitate subsequent material movement.

The lower tongue plate lifting drive source 33 is a cylinder fixed to the top surface of the first longitudinal movable seat 42, and the upper end of the cylinder piston rod of the lower tongue plate lifting drive source 33 is fixedly connected to the lower tongue plate base 32.

[0082] When the cylinder piston rod of the lower tongue plate lifting drive source 33 extends upward or retracts downward, the lower tongue plate base 32 is driven to move upward or downward, and the lower tongue plate 31 is also driven to move upward or downward. At the same time, the lower tongue plate quick release assembly 37 is detachable as a whole, which is convenient for replacing lower tongue plates 31 of different specifications and models to meet different sewing needs. Of course, in other embodiments, the lower tongue plate lifting drive source 33 can also be a motor.

[0083] Furthermore, the structure of the upper tongue plate unit 20 is preferably as follows: Figure 5 , Figure 7 and Figure 8 As shown, the upper tongue plate unit 20 includes an upper tongue plate base 23 and the above-mentioned lateral shift drive source 22. The upper tongue plate base 23 is installed on the upper side of the lower tongue plate base 32 so as to be movably installed up and down.

Preferably, the upper tongue plate unit 20 also includes a guide rod 214 extending up and down, and a linear bearing 215 fixed in the lower tongue plate base 32; the upper end of the guide rod 214 is fixed in the upper tongue plate base 23, and the guide rod 214 is supported in the linear bearing 215 so as to be movable up and down, and the lower end of the guide rod 214 is distributed on the upper side of the lower tongue plate base 32, and there is a spacing between the two; the upper tongue plate lifting drive source 24 is a cylinder fixed on the bottom surface of the lower tongue plate base 32, and the upper end of the cylinder piston rod of the upper tongue plate lifting drive source 24 is connected to the upper tongue plate base 23, and the connection mode can be upward abutment or fixed connection. When the cylinder piston rod of the upper tongue plate lifting drive source 24 extends upward or retracts downward, the upper tongue plate base 23 is driven to move up or down, and the upper tongue plate 21 is also driven to move up or down. Of course, in other embodiments, the upper tongue plate lifting drive source 24 can also adopt a motor.

[0084] Furthermore, if Figure 7 and Figure 8As shown, the upper tongue plate unit 20 also includes a second longitudinal movement drive source 25, a second longitudinal movement movable seat 26, a second longitudinal movement connecting block 27, and a second linear guide assembly 28 extending forward and backward. The second longitudinal movement movable seat 26 is installed on the top surface of the upper tongue plate base 23 so as to be movably mounted forward and backward through the second linear guide assembly 28; the second longitudinal movement drive source 25 is a cylinder, and both ends of the cylinder piston rod of the second longitudinal movement drive source 25 are fixedly connected to the upper tongue plate base 23, and both ends of the second longitudinal movement connecting block 27 are respectively fixedly connected to the cylinder body of the second longitudinal movement drive source 25 and the second longitudinal movement movable seat 26, thereby connecting the second longitudinal movement drive source 25 with the second longitudinal movement movable seat 26 in transmission; the lateral movement drive source 22 is fixed on the second longitudinal movement movable seat 26. In this way, when the cylinder piston rod of the second longitudinal drive source 25 is extended and retracted forward and backward, the cylinder body of the second longitudinal drive source 25 will be driven to move backward or forward accordingly, and the second longitudinal connection block 27, the second longitudinal movable seat 26, the lateral drive source 22 and the upper tongue plate 21 will be driven to move backward or forward together. This structure drives the upper tongue plate 21 forward or backward alone, so that after the upper cloth piece 100 and the lower cloth piece 200 are folded, the upper tongue plate 21 is first driven backward by the second longitudinal drive source 25, so that the upper tongue plate 21 first withdraws backward from the folded upper cloth piece 100; then, the upper tongue plate unit 20 and the lower tongue plate unit 30 are driven backward as a whole by the first longitudinal drive source 41, so that the lower tongue plate 31 withdraws backward from the folded lower cloth piece 200.

[0085] Furthermore, if Figure 7 and Figure 8 As shown, the upper tongue plate unit 20 also includes an upper tongue plate quick-release assembly 29, an upper quick-change base 210, a third linear guide assembly 211 extending left and right, and an adapter block 212; the upper quick-change base 210 is installed on the top surface of the second longitudinal movable seat 26 so as to be movable left and right through the third linear guide assembly 211; the lateral drive source 22 is directly connected to the upper quick-change base 210 through the adapter block 212 to drive the upper quick-change base 210 to move left and right; the upper tongue plate quick-release assembly 29 includes the above-mentioned upper tongue plate 21, and the upper tongue plate quick-release assembly 29 is detachably connected to the upper quick-change base 210 through screws. Preferably, the connection structure between the lateral drive source 22 and the upper quick-change base 210 is as follows: Figure 7 and Fig. 9As shown, the lateral shift driving source 22 is a cylinder, and a stepped groove is opened in the upper quick-change base 210, and the stepped groove includes a first groove body 2101 and a second groove body 2102 which are connected, and the width of the first groove body 2101 in the front-to-back direction is smaller than the width of the second groove body 2102; the adapter block 212 includes a connecting shaft section 2121 and a clamping shaft section 2122, and the connecting shaft section 2121 and the clamping shaft section 2122 are both cylindrical sections, and the outer diameter of the connecting shaft section 2121 is smaller than the outer diameter of the clamping shaft section 2122; the connecting shaft section 2121 is accommodated in the first groove body 2101 and is connected to the left end of the cylinder piston rod of the lateral shift driving source 22, and the clamping shaft section 2122 is accommodated in the second groove body 2102 and is abutted against the left and right side groove walls of the second groove body 2102. Thus, when the cylinder piston rod of the lateral shift driving source 22 extends to the left or retracts to the right, the drive adapter block 212, the upper quick-change base 210 and the upper tongue plate quick-release assembly 29 are driven to move left or right together, thus driving the upper tongue plate 21 to move left or right.

[0087] In summary, the working process of the tongue plate mechanism for shoulder strap folding having the above structure is as follows.

[0088] 1. Initial state before locking: the cylinder piston rod of the first longitudinal shift drive source 41 retracts forward, and the cylinder piston rod of the second longitudinal shift drive source 25 extends backward, and the corresponding upper tongue plate 21 and lower tongue plate 31 are both in the forward position; the cylinder piston rod of the lower tongue plate lifting drive source 33 retracts downward, and the corresponding lower tongue plate 31 is in a low position; the cylinder piston rod of the upper tongue plate lifting drive source 24 extends upward, and the corresponding upper tongue plate 21 is in a high position; the cylinder piston rod of the lateral shift drive source 22 retracts to the right, and the corresponding upper tongue plate 21 is in the right limit position, and the upper tongue plate 21 and the lower tongue plate 31 are facing each other up and down.

[0089] Second, the push plate in the cloth folding device folds the upper bevel 101 of the front left end of the upper cloth piece 100 slightly inward, and the other push plate in the cloth folding device folds the lower bevel 201 of the front right end of the lower cloth piece 200 slightly inward.

[0090] 3. The cylinder piston rod of the lateral shift driving source 22 extends to the left, driving the adapter block 212, the upper quick-change base 210 and the upper tongue plate quick-release assembly 29 to move left together, so that the upper tongue plate 21 moves left to the left limit position, and the upper cloth piece 100 and the lower cloth piece 200 are staggered left and right.

[0091] Fourth, the cylinder piston rod of the upper tongue plate lifting drive source 24 retracts downward, driving the upper tongue plate base 23 to move downward, causing the upper tongue plate 21 to move downward, and the upper tongue plate 21 is in a low position.

[0092] Fifth, the cylinder piston rod of the lateral shift driving source 22 retracts and resets to the right, causing the upper tongue plate 21 to move rightward to the right limit position, thereby causing the upper bevel 101 of the front left end of the upper fabric piece 100 and the lower bevel 201 of the front right end of the lower fabric piece 200 to partially overlap.

[0093] 6. The push plate in the cloth folding device folds the lower right end lower bevel 201 of the lower cloth piece 200 completely inward, and the push plate in the cloth folding device folds the upper left end upper bevel 101 of the upper cloth piece 100 completely inward, so that the upper left end upper bevel 101 of the upper cloth piece 100 completely enters the buckled edge of the lower cloth piece 200 to complete the buckling.

[0094] 7. The cylinder piston rod of the second longitudinal driving source 25 extends forward, and the cylinder body of the second longitudinal driving source 25 moves backward, driving the upper tongue plate 21 to move backward, and the upper tongue plate 21 withdraws backward from the folded upper cloth piece 100.

[0095] 8. The cylinder piston rod of the first longitudinal driving source 41 extends backward, driving the first longitudinal moving seat 42, the upper tongue plate unit 20 and the lower tongue plate unit 30 to move backward as a whole, the upper tongue plate 21 and the lower tongue plate 31 move backward to the rearmost position, and the lower tongue plate 31 withdraws backward from the folded lower cloth piece 200.

[0096] In the tongue plate mechanism for shoulder loop folding involved in the present application, the upper and lower tongue plates 21 and the lower tongue plates 31 are lifted and lowered to close the upper and lower pieces of cloth or position the pieces of cloth for subsequent material transfer and sewing; the upper and lower pieces of cloth are buckled by the left and right movement of the upper tongue plate 21; the upper and lower pieces of cloth are combined by the forward and backward movement of the upper tongue plate 21 and the lower tongue plate 31, and when the material transfer device is in place and completely fixes the combined pieces of cloth, the upper tongue plate 21 and the lower tongue plate 31 retreat to avoid interference with the subsequent material transfer action of the material transfer device. Therefore, the mechanism of the present application has a high degree of freedom and can adapt to the folding action of pieces of cloth in various positions; combined with the three-axis spatial movement of the upper tongue plate 21, the entire folding process can be controlled by the adjustment mechanism, which is more stable and reliable, and meets more processing methods of piece folding and sewing.

[0097] In summary, the utility model effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0098] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
