[0002] The pocket patching machine is mainly used to place and sew bag-shaped fabrics on jeans, shirts, etc. The folding device is an important part of the pocket patching machine. When working, a piece of bag-shaped fabric is usually placed on the bag-shaped plate (tongue plate), and the corresponding sides of the bag-shaped fabric are folded using the matching die and folding knife (folding piece).

[0058] Unless otherwise defined, all technical and scientific terms used in the description of this application have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in the description of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the description of this application includes any and all combinations of one or more of the related listed items.

[0059] In the prior art, the female die of a pocket attaching machine cooperates with a pocket-shaped plate through its female die wall to act on pocket-shaped fabric, and then a folding knife folds the edge of the pocket-shaped fabric. When the pocket size changes, it is necessary to replace the female die and adjust the folding knife, which affects the operation efficiency.

[0060] See Figures 1 to 5 , in an embodiment of this application, a modular linkage adjustment mechanism for a pocket attaching machine is provided, including a base plate 100 and at least two sets of folding assemblies 300 installed on the base plate 100. The base plate 100 can serve as an installation platform for other components and has opposite top and bottom sides. Multiple sets of folding assemblies 300 jointly provide a female die 200, and each set of folding assemblies 300 also provides a folding knife 310, where the female die 200 and the folding knife 310 are located on the bottom side of the base plate 100. As for the pocket attaching machine as a whole, the number of folding assemblies 300 shown in this embodiment or in the drawing is not strictly limited to all the folding assemblies 300 in the pocket attaching machine, but at least includes more than two sets.

[0061] The die 200 has a die wall that matches the preset bag shape. As one of the improvements of the present application, the die wall adopts a split structure. For example, each set of folding components 300 includes a unit wall 210 and a folding knife 310. The unit wall 210 is installed on the base plate 100 with adjustable position. The unit walls 210 of all folding components 300 cooperate with each other to form a shape-adjustable die 200. The die 200 as a whole includes multiple unit walls 210, for example, 2 to 8 units. Each unit wall 210 is respectively connected to each set of folding components 300, and the relative positions between them can be changed as needed to adapt to different bag sizes. For the convenience of adjustment, each unit wall 210 is installed on the bottom side of the base plate 100 in a sliding position, that is, it can slide relative to the base plate 100 to change the position when adjustment is required, and lock the position after the adjustment is completed.

[0062] The die wall is generally U-shaped, with an open side and a closed side opposite to each other, the open side corresponds to the bag opening, and the closed side corresponds to the bag bottom. The unit wall 210 in this embodiment includes five pieces, namely a central bag bottom unit wall, two bottom corner unit walls adjacent to the two sides of the bag bottom unit wall, and two side unit walls on both sides of the opening.

[0063] The folding knife 310 has an initial position and a working position relative to the base plate 100. The folding knife 310 is relatively far away from the bag-shaped plate in the initial position, and relatively close to the bag-shaped plate in the working position, so as to squeeze and fold the bag-shaped cloth. The folding knife 310 is movably connected to the cell wall 210, and the folding knife 310 can be switched between the initial position and the working position. When the folding knife 310 and the cell wall 210 need to be adjusted to adapt to the new bag size, the folding knife 310 can also follow the position adjustment of the cell wall. In order to adapt to the new bag size, it can be understood that the folding knife 310 has changed its working position after the position adjustment. Of course, if the travel distance between the initial position and the working position is kept unchanged during the adjustment, it can be understood that the initial position has been changed relative to the base plate 100 after the adjustment.

[0064] In this embodiment, the folding assembly 300 adopts a modular design, breaking the concept of an integrated die, and can adjust the folding knife 310 and the unit wall 210 in a linked manner, taking into account the accuracy of their relative positions, thereby further improving work efficiency.

[0065] In one embodiment, the modular linkage adjustment mechanism further includes a first driving mechanism 400, which is transmission-connected to all the folding assemblies 300 to drive each unit wall 210 and the folding knife to adjust the position.

[0066] The first driving mechanism 400 can utilize the same power device in conjunction with an improved linkage assembly to simultaneously drive all controlled unit walls 210 , thereby simplifying the structure and reducing costs.

[0067] In one embodiment, the power device may adopt a manual torsion shaft 410, which may be manually driven and / or equipped with a power source. The torsion shaft 410 is rotatably mounted on the base plate 100, and each set of folding components 300 is arranged around the axis of the torsion shaft 410; the linkage component is transmission-connected between the torsion shaft 410 and each unit wall 210.

[0068] All the controlled unit walls 210 have different adjustment directions, that is, at least two unit walls 210 have different movement directions (non-parallel) when adjusting their positions. In this embodiment, all the controlled unit walls 210 have different movement directions when adjusting, and generally tend to converge or diverge outward.

[0069] In order to guide the movement of the unit wall 210, each unit wall 210 is fixed to the corresponding sliding seat 220, and a guide seat 110 is fixed to the bottom side of the substrate 100. The sliding seat 220 slidably cooperates with the guide seat 110. For example, a track 222 can be fixed to the top of the sliding seat 220, and the sliding seat 220 slidably cooperates with the guide seat 110 through the track 222.

[0070] The substrate 100 is provided with a strip-shaped guide hole 120 for each sliding seat 220, and the sliding seat 220 is connected with a first transmission member 221 inserted into the corresponding guide hole 120. The first transmission member 221 and the sliding seat 220 are fixed to each other, and move along the corresponding guide hole 120 when adjustment is required. The multiple guide holes 120 are roughly radially distributed. As for the first transmission member 221 itself, it can be a transmission pin vertically fixed to the sliding seat 220.

[0071] See also Figure 6 In one embodiment, each folding assembly 300 also includes a second driving mechanism 320, which is installed on the base plate 100. The folding knife 310 and the second driving mechanism 320 are connected to each other through a locking mechanism 500. The locking mechanism 500 includes a locking member, which enables the locking mechanism 500 to have a locking state for maintaining the linkage between the second driving mechanism 320 and the folding knife 310, and a released state for releasing the linkage. In order to adapt to the follow-up adjustment of the folding knife 310 and the unit wall 210, the locking mechanism 500 allows the folding knife 310 to change its relative position with the second driving mechanism 320 in the released state, that is, changes the matching position.

[0072] Depending on the driving type, the locking member can be an automatic locking member 520 or a manual locking member 530. The driving method of the automatic locking member 520 is to automatically switch the state of the locking mechanism 500 according to the control signal through an interlocking power source (motor, cylinder, etc.); and the driving method of the manual locking member 530 is manual operation to switch the state of the locking mechanism 500.

[0073] Furthermore, the locking mechanism 500 further includes a coupling seat 510 which is mainly used for the transitional connection between the second driving mechanism 320 and the folding knife 310, provides a structural basis for cooperation with other components, and necessary support. In the locking mechanism 500, multiple locking members of the same type or multiple locking members of different types can be configured. Between the second driving mechanism 320 and the coupling seat 510, and between the coupling seat 510 and the folding knife 310, at least one locking member for switching the state of the locking mechanism is configured. When locking members are configured at both places, the types of the locking members can be the same or different.

[0074] Specifically, the transmission mode between the second driving mechanism 320 and the folding knife 310 can be:

[0075] Mode a), the second driving mechanism 320 is directly transmitted to the coupling seat 510, and the coupling seat 510 and the folding knife 310 are transmitted through an automatic locking member 520 or a manual locking member 530.

[0076] Direct transmission does not strictly limit the number of components participating in the transmission. It is only relative to the automatic locking member 520 and the manual locking member 530, that is, direct transmission always maintains a transmission connection during normal use and cannot switch the state of the locking mechanism 500.

[0077] Mode b), the second driving mechanism 320 and the coupling seat 510 are transmitted by a first automatic locking member, and the coupling seat 510 and the folding knife 310 are transmitted by direct transmission, a second automatic locking member or a manual locking member 530.

[0078] As a further explanation, automatic locking members can be used simultaneously between the second driving mechanism 320 and the coupling seat 510, and between the coupling seat 510 and the folding knife 310. Of course, the automatic locking members at the two places are configured separately.

[0079] Mode c), the second driving mechanism 320 and the coupling seat 510 are transmitted by a first manual locking member, and the coupling seat 510 and the folding knife 310 are transmitted by direct transmission, an automatic locking member 520 or a second manual locking member.

[0080] As a further explanation, manual locking members can be used simultaneously between the second driving mechanism 320 and the coupling seat 510, and between the coupling seat 510 and the folding knife 310. Of course, the manual locking members at the two places are configured separately.

[0081] For example, the second driving mechanism 320 may adopt a push-pull cylinder 322 fixed to the substrate 100. The folding knife 310 is linked to the piston rod of the push-pull cylinder 322. Since the folding knife 310 moves relative to each unit wall 210 during operation, in this embodiment, in order to adjust the folding knife 310 while adjusting the unit wall 210 and allowing relative movement between the unit wall 210 and the folding knife 310, the connection method between the two is also improved. A reset member 350 is provided between the unit wall 210 and the tool holder 330 to achieve a resetable movable connection between the unit wall 210 and the folding knife 310.

[0082] Reference line A is the position of the push-pull cylinder 322 fixed to the substrate 100. The middle part in the upper and lower parts of the figure shows the folding knife 310 in the initial state, and the upper and lower parts of the figure are referenced with this middle part.

[0083] The lower part of the figure shows that the substrate 100 and the unit wall 210 remain in place, while the coupling seat 510 is linked to the folding knife 310 and the piston rod of the push-pull cylinder 322. The push-pull cylinder 322 drives the folding knife 310 and the coupling seat 510 to move. The folding knife 310 enters the working position. The folding knife 310 has a relative displacement to the left in the figure relative to the unit wall 210, and the reset member 350 deforms accordingly.

[0084] The upper part of the figure shows that the substrate 100, the push-pull cylinder 322, and the coupling seat 510 remain in place. The coupling seat 510 releases the linkage between the folding knife 310 and the piston rod of the push-pull cylinder 322. When the first driving mechanism 400 adjusts the initial positions of the unit wall 210 and the folding knife 310, the first transmission member 221, the track 222, the sliding seat 220, the unit wall 210, and the folding knife 310 move synchronously to the left in the figure. After the adjustment is completed, the coupling seat 510 restores the linkage between the folding knife 310 and the push-pull cylinder 322.

[0085] See Figure 7 , Figure 8 , in one embodiment, the first driving mechanism 400 further includes a motor 440 as a power device. The motor 440 has the advantages of being easy to achieve automatic control and high adjustment accuracy. It can also cooperate with sensors to detect the position signals of moving parts, perform information feedback and corresponding control. After the adjustment is completed, the motor 440 can be self-locked to maintain the positions of the unit walls 210. The transmission cooperation between the motor 440 and the first transmission member 221 can adopt different forms such as cams, linkages, and gears. Preferred embodiments are also provided below.

[0086] In one embodiment, an elevated bracket 130 is fixed above the substrate 100. The motor 440 is installed on the bracket 130. The motor shaft of the motor 440 is drivingly connected to the torsion shaft 410 through a universal joint 450. The torsion shaft 410 is vertically arranged, that is, perpendicular to the substrate 100. The motor 440 is horizontally arranged to reduce space occupation, and the universal joint 450 can effectively transmit and bear a large torque.

[0087] The top of the torsion shaft 410 is rotatably fitted to the bracket 130, and the bottom of the torsion shaft 410 is rotatably fitted to the substrate 100. The linkage assembly includes a synchronous plate 420 and a linkage plate 430. The synchronous plate 420 is fixed to the bottom of the torsion shaft 410. Two strip-shaped synchronous holes 421 are formed in the synchronous plate 420, and the extending direction of each synchronous hole 421 is obliquely intersecting with the radial direction of the torsion shaft 410. There are two linkage plates 430, which are respectively arranged on two opposite sides in the radial direction of the torsion shaft 410, and the synchronous plate 420 is stacked on the two linkage plates 430. A second transmission member 431 is fixed on each linkage plate 430. The second transmission member 431 can be a transmission pin vertically fixed to the linkage plate 430 or other means. The second transmission member 431 extends into the corresponding synchronous hole 421.

[0088] The synchronous plate 420 moves by rotating with the torsion shaft 410, and then drives each linkage plate 430 through the synchronous hole 421 and the second transmission member 431. In order to limit the movement direction of the linkage plate 430, strip-shaped second guiding holes 433 are formed in each linkage plate 430, and a guiding pin 140 extending into the second guiding hole 433 is fixed on the substrate 100. It can be seen in the figure that all the second guiding holes 433 have the same extending direction, for example, all extend in the front-back direction (corresponding to the up-down direction in Figure 2 ), that is, the two linkage plates 430 can move synchronously and reversely, approaching or departing from the torsion shaft 410 synchronously.

[0089] The cooperation mode between each linkage plate 430 and the sliding seat 220 is that the first transmission member 221 on the sliding seat 220 can be directly fixed to the linkage plate 430.

[0090] Alternatively, a plurality of driving holes 432 are formed in the linkage plate 430, the first transmission member 221 extends into the corresponding driving hole 432, the driving hole 432 is a strip-shaped hole and is obliquely intersecting with the corresponding guiding hole 120, and the first transmission member 221 movably penetrates through the intersecting area of the guiding hole 120 and the driving hole 432.

[0091] Since the movement directions of the unit walls 210 and the linkage plate 430 may not be the same during adjustment, in this case, since the driving hole 432 is obliquely intersecting with the corresponding guiding hole 120, the component force in the unexpected direction can be released to ensure the smooth movement of the first transmission member 221 along the guiding hole 120.

[0092] Among the five unit walls 210 described above, the bottom unit wall of the bag and the two bottom corner unit walls are linked to one linkage plate, and the two side unit walls are linked to another linkage plate. Among them, the bottom unit wall of the bag directly follows the movement of the linkage plate 430, while the other four unit walls 210 are adjusted to have a movement direction inconsistent with that of the linkage plate 430.

[0093] In some cases, when the shape of a certain unit wall 210 or the folding knife 310 itself needs to be adjusted, disassembly and replacement are required. For the convenience of operation, the following preferred methods are provided.

[0094] See Figure 9 、 Figure 10 , in one embodiment, the sliding seat 220 and the unit wall 210 are detachably connected in a magnetic attraction manner. The top of the sliding seat 220 is provided with a track 222 that cooperates with the guiding seat 110. Of course, the guiding seat 110 and the track 222 are relative. Vice versa, such naming is only for the convenience of reading and does not strictly limit whether their positions can be interchanged.

[0095] A magnetic attracting member 223 is embedded inside or at the bottom of the sliding seat 220, and the unit wall 210 is magnetically attracted through the attracting member 223. For example, a connecting plate 211 can be fixed on the top surface of the unit wall 210, and the connecting plate 211 is attached to the bottom of the sliding seat 220. When disassembly is required, the unit wall 210 and the folding knife 310 can be separated from the bottom of the sliding seat 220 only by overcoming the magnetic attraction force. A latching structure with complementary shapes can also be provided between the sliding seat 220 and the connecting plate 211 to further prevent misalignment and improve the assembly accuracy.

[0096] In one embodiment, the unit wall 210 and the folding knife 310 adopt a resetable movable connection. Generally speaking, the folding knife 310 and the unit wall 210 are in sliding cooperation. In order to take into account synchronous adjustment, a limiting mechanism for limiting the sliding limit distance is provided between the folding knife 310 and the unit wall 210. For example, a knife seat 330 is fixed at the tail of the folding knife 310, a guiding rod 224 is fixed on the unit wall 210, and the knife seat 330 is provided with a first guiding hole 331 for the guiding rod 224 to slide through. One end of the guiding rod 224 passing through the knife seat 330 is provided with a limiting head 225, and the knife seat 330 and the limiting head 225 constitute the limiting mechanism, so that the folding knife 310 is blocked by the limiting head 225 in the initial position.

[0097] In one embodiment, the resetting member 350 is a spiral compression spring sleeved on the guiding rod 224. Under the action of the resetting member 350, the relative position with the unit wall 210 can be maintained. When the folding knife 310 tends to the working position, the spiral compression spring is compressed to store energy.

[0098] The limiting mechanism and the reset member 350 cooperate with each other. When the folding knife 310 is disengaged from the second driving mechanism 320 and its position is adjusted, the folding knife 310 can move synchronously with the unit wall 210 to ensure the stability of the relative position. After the position adjustment is completed, the linkage between the folding knife 310 and the second driving mechanism 320 can be restored.

[0099] As a whole, the second driving mechanism 320 has an output member 321 that is located on the downstream side and is movable in the transmission order. The folding knife 310 is fixed with a handle portion 340, and the locking mechanism 500 can be connected between the handle portion 340 and the output member 321. The position-adjustable transmission connection method can specifically adopt a locking cylinder, a manual bolt, meshing, a tight fit, magnetic attraction, and so on.

[0100] Since the adjustment between the unit wall 210 and the folding knife 310 is not in a step-by-step manner, it may be only a fine adjustment or requires stepless adjustment. To achieve automatic control, an automatic locking member 520 is preferably provided in the position-adjustable transmission connection, so that the switching between the locked state and the released state can be realized through automatic control, and it is also suitable for stepless adjustment. The automatic locking member 520 can, for example, adopt a locking cylinder 511 to lock or release the handle portion 340 and allow the handle portion 340 to slide and adjust.

[0101] To facilitate disassembly and assembly and maintain the relative position between the folding knife 310 and the second driving mechanism 320 before and after disassembly and assembly, a manual locking member 530 can also be provided in the locking mechanism 500. When in use, the manual locking member 530 remains in linkage, and when disassembly is required, the linkage is released for separation. The manual locking member 530 preferably adopts a structure that can be quickly positioned for disassembly and assembly, such as a positioning pin or a clamping method, and so on.

[0102] Combined with Figure 11 、 Figure 12 , in one embodiment, to implement the above connection method and carry related components, the locking mechanism 500 includes a combination seat 510, an automatic locking member 520, and a manual locking member 530. One of the automatic locking member 520 and the manual locking member 530 acts between the combination seat 510 and the second driving mechanism 320, and the other acts between the combination seat 510 and the folding knife 310.

[0103] In one embodiment, the second driving mechanism 320 is a push-pull cylinder 322, the output member 321 is a connection seat fixed to the piston rod of the push-pull cylinder 322, and the manual locking member 530 acts between the connection seat and the combination seat 510. For example, there are mating pin holes between the connection seat and the combination seat 510, and the manual locking member 530 is a positioning pin inserted into the corresponding pin hole. When disassembling, the combination seat 510 and the second driving mechanism 320 can be quickly separated through the manual locking member 530. Combining with the magnetic attraction method between the unit wall 210 and the sliding seat 220, the unit wall 210 and the folding knife 310 can be quickly removed.

[0104] In one embodiment, a first limiting hole 512 is provided at the bottom of the coupling seat 510. The handle portion 340 is inserted into the first limiting hole 512. The automatic locking member 520 is a locking cylinder 511 installed in the coupling seat 510. A limiting head 513 that interacts with the handle portion 340 is provided on the piston rod of the locking cylinder 511. In order to adapt to the adjustment, disassembly and assembly of the folding knife 310, a slotted hole 341 with one end open is provided on the handle portion 340. The piston cylinder of the locking cylinder 511 passes through the slotted hole 341, and the limiting head 513 is located at one end where the piston cylinder passes through the slotted hole 341.

[0105] For auxiliary support, the track 222 extends and penetrates through the coupling seat 510. The penetrating part adopts a sliding fit to avoid interfering with the movement of the coupling seat 510 and the folding knife 310.

[0106] When adjustment is required, the locking cylinder 511 is released. The handle portion 340 can move relative to the locking cylinder 511 to any position within the stroke range. After the unit wall 210 and the folding knife 310 are adjusted by using the first driving mechanism 400, the locking cylinder 511 locks the handle portion 340 again.

[0107] The adjustment direction of the unit wall 210 is restricted by the guiding hole 120, and the arrangement directions of the guiding seat 110 and the track 222 correspond to it. For example, the extending direction of the guiding hole 120 is the first direction, and the folding knife 310 moves along the second direction during operation. If the first direction is parallel to the second direction, such as the bottom unit wall of the bag and the two bottom corner unit walls, when adjusting the unit wall, after the locking mechanism 500 releases the locking of the handle portion 340 of the folding knife 310, it can be adjusted following the movement without interference in the movement direction.

[0108] In some cases, for example, in the two side unit walls, the first direction and the second direction are inclined to each other. When the unit wall 210 is adjusted along the first direction, the folding knife 310 cannot directly follow the movement because it moves along the second direction relative to the second driving mechanism and there is interference in the movement direction.

[0109] To solve this problem, refer to Figure 13 、 Figure 14 In one embodiment, between the locking mechanism 500 and the second driving mechanism, or a sliding joint that cooperates along the third direction is provided inside the locking mechanism 500. The setting method of the sliding joint can be that the coupling seat 510 itself is a split structure with a sliding fit. One part of the split structure is connected to the second driving mechanism 320, and the other part is connected to the folding knife 310.

[0110] The sliding joint in the figure includes a sliding seat 323 and a sliding rail 324 that cooperate with each other. The sliding seat 323 is fixed to the bottom of the output member 321, and the sliding rail 324 can be fixed to the joint seat 510 and slide along the third direction, where the third direction can be perpendicular to the second direction. The first direction suitable for the movement of the folding knife 310 can be synthesized through the third direction and the second direction. When adjusting the unit wall 210, the sliding seat 323 and the sliding rail 324 slide adaptively. The above-mentioned first direction, second direction, and third direction are all arranged in the parallel plane of the substrate 100.

[0111] Based on the above, an embodiment of the present application further provides a pocket pasting machine with the modular linkage adjustment mechanism for the pocket pasting machine in the above embodiments. The structures of other parts of the pocket pasting machine can be implemented in combination with the prior art.

[0112] In the modular linkage adjustment mechanism for the pocket pasting machine of the present application, the female die and the folding knife are modularly designed as a whole, which can be quickly adjusted to adapt to different pocket sizes, and scaling can be achieved in combination with automatic control, which can reduce the production and debugging of jigs and further reduce costs.
