Description

Technical Field

[0001] This application relates to the field of sewing equipment technology, and more particularly to a modular linkage adjustment mechanism for a bag-applying machine and the bag-applying machine itself. Background Technology

[0002] Patch attaching machines are mainly used to attach and sew pocket-shaped fabric to jeans, shirts, etc. The folding mechanism is a crucial part of the patch attaching machine. During operation, a piece of pocket-shaped fabric is placed on a flap plate (latch), and then a matching die and folding blade (folding sheet) are used to fold the corresponding sides of the fabric. This requires making and installing the corresponding die and folding blade according to the pocket size.

[0003] For different bag sizes, it is necessary to change the die or adjust the folding blades one by one, which is cumbersome and affects production efficiency. Moreover, it is difficult to take into account the relative positions of multiple folding blades and between the folding blades and the die during the adjustment process. Summary of the Invention

[0004] This application provides a modular linkage adjustment mechanism that enables the concave die and folding knife to change positions synchronously, which can improve work efficiency and quickly adapt to different bag sizes.

[0006] Unit walls, which are mounted on the substrate in adjustable positions, and the unit walls of all folding components cooperate with each other to form an adjustable-shape concave mold;

[0007] A folding blade has an initial position and a working position relative to the substrate. The folding blade is movably connected to the unit wall to switch between the initial position and the working position. The folding blade also moves with the unit wall to adjust its position.

[0017] In one embodiment, each folding assembly further includes:

[0018] The second drive mechanism is mounted on the base plate and is used to drive the folding blade to switch between the initial position and the working position;

[0019] A locking mechanism is connected between the second drive mechanism and the folding knife. The locking mechanism has a locked state that keeps the second drive mechanism and the folding knife linked together, and a released state that releases the linkage. In the released state, the folding knife is allowed to move along the unit wall to adjust its position.

[0020] In one embodiment, the locking mechanism includes a locking member, which switches the locking mechanism to:

[0021] In the locked state, the second drive mechanism is kept in a transmission connection with the folding knife, and the folding knife has multiple engagement positions relative to the second drive mechanism;

[0022] In the released state, the transmission connection is disconnected, and the engagement position of the folding knife can be changed.

[0023] In one embodiment, the locking mechanism includes a coupling seat and a locking member, wherein the locking member is an automatic locking member and / or a manual locking member, and the automatic locking member and the manual locking member switch the locking mechanism between the locking state and the releasing state through corresponding driving methods;

[0058] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0059] In the existing technology, the die of the bag-applying machine interacts with the bag-shaped plate through its die wall to apply to the bag-shaped fabric, and then the edge of the bag-shaped fabric is folded by the folding knife. When the bag size changes, the die needs to be replaced and the folding knife needs to be adjusted, which affects the work efficiency.

[0060] See Figures 1-5 This application provides a modular linkage adjustment mechanism for a bag-applying machine, including a base plate 100 and at least two sets of folding assemblies 300 mounted on the base plate 100. The base plate 100 serves as a mounting platform for other components and has opposing top and bottom sides. Multiple sets of folding assemblies 300 collectively provide a die 200, and each set of folding assemblies 300 also provides a folding blade 310, wherein the die 200 and the folding blade 310 are located on the bottom side of the base plate 100. Regarding the bag-applying machine as a whole, the number of folding assemblies 300 shown in this embodiment or the figures is not strictly limited to all folding assemblies 300 in the bag-applying machine, but at least two sets are included.

[0061] The die 200 has a die wall that matches the preset bag shape. As one of the improvements in this application, the die wall adopts a split structure. For example, each set of folding components 300 includes a unit wall 210 and a folding blade 310. The unit wall 210 is mounted on the substrate 100 in an adjustable position. The unit walls 210 of all folding components 300 cooperate with each other to form an adjustable die 200. The die 200 as a whole includes multiple unit walls 210, such as 2 to 8. Each unit wall 210 is connected to and belongs to each set of folding components 300, and their relative positions can be changed as needed to adapt to different bag sizes. For easy adjustment, each unit wall 210 is slidably mounted on the bottom side of the substrate 100. That is, when adjustment is needed, it can slide relative to the substrate 100 to change its position. After adjustment, the position is locked.

[0062] The concave wall is generally U-shaped, with an open side and a closed side. The open side corresponds to the bag opening and the closed side corresponds to the bag bottom. In this embodiment, the unit wall 210 includes 5 pieces, namely the 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 blade 310 has an initial position and a working position relative to the substrate 100. In the initial position, the folding blade 310 is relatively far away from the bag-shaped plate, and in the working position, it is relatively close to the bag-shaped plate to compress and fold the bag-shaped fabric. The folding blade 310 is movably connected to the unit wall 210. The folding blade 310 can switch between the initial position and the working position. When it is necessary to adjust the folding blade 310 and the unit wall 210 to adapt to the new bag size, the folding blade 310 can also adjust its position according to the unit wall. In order to adapt to the new bag size, it can be understood that the folding blade 310 changes its working position after the position is adjusted. Of course, if the travel distance between the initial position and the working position remains unchanged during adjustment, it can be understood that the initial position relative to the substrate 100 has changed after adjustment.

[0064] In this embodiment, the folding component 300 adopts a modular design, breaking away from the concept of an integrated concave mold. It can adjust the folding blade 310 and the unit wall 210 in a coordinated manner, taking into account the accuracy of their relative positions and improving work efficiency in one step.

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

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

[0067] In one embodiment, the power unit may be a manually operated 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 driven between the torsion shaft 410 and each unit wall 210.

[0068] All controlled unit walls 210 have different adjustment directions, that is, at least two unit walls 210 do not move in the same direction (not parallel to each other) when adjusting. In this embodiment, all controlled unit walls 210 move in different 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. The bottom side of the base plate 100 is fixed with a guide seat 110. The sliding seat 220 and the guide seat 110 are slidably engaged. For example, a track 222 can be fixed to the top of the sliding seat 220, and the track 222 is slidably engaged with the guide seat 110.

[0070] The substrate 100 has strip-shaped guide holes 120 for each sliding seat 220. A first transmission member 221 is connected to the sliding seat 220 and inserted into the corresponding guide hole 120. The first transmission member 221 is fixed to the sliding seat 220. When adjustment is needed, it moves along the corresponding guide hole 120. The multiple guide holes 120 are roughly radially distributed. The first transmission member 221 itself can be a transmission pin or the like that that is vertically fixed to the sliding seat 220.

[0071] See Figure 6 In one embodiment, each folding assembly 300 further includes a second drive mechanism 320, which is mounted on the substrate 100. The folding blade 310 and the second drive mechanism 320 are connected by a locking mechanism 500. The locking mechanism 500 includes a locking member, which enables the locking mechanism 500 to have a locked state that keeps the second drive mechanism 320 and the folding blade 310 in motion, and a released state that releases the connection. In order to adapt to the follow-up adjustment of the folding blade 310 and the unit wall 210, the locking mechanism 500 in the released state allows the folding blade 310 to change its relative position with the second drive mechanism 320, that is, to change the mating position.

[0072] Depending on the type of drive, the locking component can be an automatic locking component 520 or a manual locking component 530. The automatic locking component 520 is driven by a linked power source (motor, cylinder, etc.) that automatically switches the state of the locking mechanism 500 according to the control signal. The manual locking component 530 is driven by manual operation to switch the state of the locking mechanism 500.

[0073] Furthermore, the locking mechanism 500 also includes a connecting seat 510, which is mainly used for the transition connection between the second drive mechanism 320 and the folding knife 310, providing a structural basis for cooperation with other components, as well as necessary support. In the locking mechanism 500, multiple locking elements of the same type or multiple locking elements of different types can be configured. At least one locking element that can switch the locking mechanism state is configured between the second drive mechanism 320 and the connecting seat 510, and between the connecting seat 510 and the folding knife 310. When locking elements are configured in both cases, the types of locking elements can be the same or different.

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

[0075] In method a), the second drive mechanism 320 is directly driven by the connecting seat 510, and the connecting seat 510 and the folding knife 310 are driven by the automatic locking member 520 or the manual locking member 530.

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

[0077] Method b), the second drive mechanism 320 and the connecting seat 510 are driven by the first automatic locking member, and the connecting seat 510 and the folding knife 310 are driven by direct drive, the second automatic locking member, or the manual locking member 530.

[0078] As further explained, automatic locking components can be used simultaneously between the second drive mechanism 320 and the coupling seat 510, and between the coupling seat 510 and the folding knife 310. Of course, the automatic locking components at the two locations are configured separately.

[0079] In method c), the second drive mechanism 320 and the connecting seat 510 are driven by the first manual locking member, and the connecting seat 510 and the folding knife 310 are driven by direct drive, automatic locking member 520 drive or second manual locking member drive.

[0080] As further explained, manual locking components can be used simultaneously between the second drive mechanism 320 and the coupling seat 510, and between the coupling seat 510 and the folding knife 310. Of course, the manual locking components at the two locations are configured separately.

[0081] For example, the second drive mechanism 320 can be a push-pull cylinder 322 fixed on the base plate 100. The folding blade 310 is linked to the piston rod of the push-pull cylinder 322. Since the folding blade 310 moves relative to each unit wall 210 during operation, in this embodiment, in order to adjust the folding blade 310 at the same time as adjusting the unit wall 210, and to allow relative movement between the unit wall 210 and the folding blade 310, the connection method between the two has been improved. A reset member 350 is provided between the unit wall 210 and the blade holder 330, realizing a resettable movable connection between the unit wall 210 and the folding blade 310.

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

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

[0084] The upper part of the figure shows the substrate 100, the push-pull cylinder 322, and the connecting seat 510 maintaining their positions. The connecting seat 510 disengages the piston rod of the folding blade 310 from the piston rod of the push-pull cylinder 322. When the unit wall 210 and the initial position of the folding blade 310 are adjusted by the first drive mechanism, the first transmission member 221, the track 222, the sliding seat 220, the unit wall 210, and the folding blade 310 move synchronously to the left side of the figure. After the adjustment is completed, the connecting seat 510 restores the linkage between the folding blade 310 and the push-pull cylinder 322.

[0085] See Figure 7 , Figure 8 In one embodiment, the first drive mechanism 400 further includes a motor 440 as a power device. The motor 440 has advantages such as easy automatic control and high adjustment accuracy. It can also cooperate with sensors to detect the position signals of moving parts, provide information feedback, and control accordingly. After adjustment, the motor 440 self-locks to maintain the position of each unit wall 210. The transmission cooperation between the motor 440 and the first transmission member 221 can adopt different forms such as cam, connecting rod, and gear. Preferred embodiments are also provided below.

[0086] In one embodiment, a raised bracket 130 is fixed above the substrate 100, and a motor 440 is mounted on the bracket 130. The motor shaft of the motor 440 is connected to the torsion shaft 410 through a universal joint 450. The torsion shaft 410 is vertically positioned, that is, perpendicular to the substrate 100. The motor 440 is horizontally positioned to reduce space occupation, and the universal joint 450 can effectively transmit and load 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 base plate 100. The linkage assembly includes a synchronization plate 420 and a connecting plate 430. The synchronization plate 420 is fixed to the bottom of the torsion shaft 410 and has two strip-shaped synchronization holes 421. The extension direction of each synchronization hole 421 is oblique to the radial direction of the torsion shaft 410. There are two connecting plates 430, which are respectively arranged on two opposite sides of the radial direction of the torsion shaft 410. The synchronization plate 420 is stacked on the two connecting plates 430. A second transmission member 431 is fixed on each connecting plate 430. The second transmission member 431 can be a transmission pin or the like that vertically fixed to the connecting plate 430. The second transmission member 431 extends into the corresponding synchronization hole 421.

[0088] The synchronous plate 420 moves by rotating with the torsion shaft 410, and then drives each connecting plate 430 through the synchronous hole 421 and the second transmission member 431. To limit the direction of movement of the connecting plates 430, each connecting plate 430 has a strip-shaped second guide hole 433. A guide pin 140 extending into the second guide hole 433 is fixed on the base plate 100. As can be seen in the figure, all the second guide holes 433 have the same extending direction, for example, they all extend in the front-to-back direction (corresponding to...). Figure 2 (Up and down direction) that is, the two connecting plates 430 can move in opposite directions synchronously, and move closer or further away from the torsion shaft 410.

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

[0090] Alternatively, the connecting plate 430 may have multiple drive holes 432, with the first transmission member 221 extending into the corresponding drive hole 432. The drive hole 432 is a strip-shaped hole that is obliquely intersecting with the corresponding guide hole 120. The first transmission member 221 is movably inserted into the intersection area of ​​the guide hole 120 and the drive hole 432.

[0091] Since the movement directions of each unit wall 210 and the linkage plate 430 may not be consistent during adjustment, in this case, since the drive hole 432 is oblique to the corresponding guide hole 120, the component force in the unexpected direction can be released, ensuring that the first transmission component 221 moves smoothly along the guide hole 120.

[0092] Of the five unit walls 210 mentioned above, the bottom unit wall and the two bottom corner unit walls are connected to one of the connecting plates, and the two side unit walls are connected to another connecting plate. The bottom unit wall is directly connected to the connecting plate 430, while the adjustment direction of the other four unit walls 210 is inconsistent with the movement direction of the connecting plate 430.

[0093] In some cases, when the shape of a certain unit wall 210 or folding blade 310 needs to be adjusted, it is necessary to disassemble and replace it. For ease of operation, the following provides a preferred method.

[0094] See Figure 9 , Figure 10 In one embodiment, the sliding seat 220 and the unit wall 210 are detachably connected by magnetic attraction. The top of the sliding seat 220 is provided with a track 222 that cooperates with the guide seat 110. Of course, the guide seat 110 and the track 222 are relative, and vice versa. Such naming is only for ease of reading and does not strictly limit whether the positions of the two can be interchanged.

[0095] The sliding base 220 has a magnetic attracting element 223 embedded inside or at the bottom, which magnetically attracts the unit wall 210. For example, a connecting plate 211 can be fixed to the top surface of the unit wall 210, and the connecting plate 211 is attached to the bottom of the sliding base 220. When disassembly is required, the unit wall 210 and the folding knife 310 can be separated from the bottom of the sliding base 220 simply by overcoming the magnetic attraction. A complementary engagement structure can also be provided between the sliding base 220 and the connecting plate 211 to further prevent misalignment and improve assembly accuracy.

[0096] In one embodiment, the unit wall 210 and the folding blade 310 are repositioned and movable. Generally, the folding blade 310 and the unit wall 210 slide together. In order to take into account synchronous adjustment, a limiting mechanism is provided between the folding blade 310 and the unit wall 210 to limit the sliding limit distance. For example, a blade holder 330 is fixed at the tail of the folding blade 310, and a guide rod 224 is fixed on the unit wall 210. The blade holder 330 has a first guide hole 331 through which the guide rod 224 slides. One end of the guide rod 224 that passes through the blade holder 330 has a limiting head 225. The blade holder 330 and the limiting head 225 constitute a limiting mechanism, so that the folding blade 310 is blocked by the limiting head 225 in the initial position.

[0097] In one embodiment, the reset member 350 is a helical compression spring sleeved on the guide rod 224. Under the action of the reset member 350, the relative position between the spring and the unit wall 210 can be maintained. When the folding knife 310 moves toward the working position, the helical compression spring is compressed and stores energy.

[0098] The limiting mechanism and the reset component 350 cooperate with each other so that when the folding blade 310 is disengaged from the second drive mechanism 320 and its position is adjusted, the folding blade 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 blade 310 and the second drive mechanism 320 can be restored.

[0099] The second drive mechanism 320, in its overall transmission sequence, has a downstream movable output component 321, a folding knife 310 with a fixed handle 340, and a locking mechanism 500 that can be connected between the handle 340 and the output component 321. The adjustable transmission connection method can specifically employ a locking cylinder, manual pin, meshing, tight fit, magnetic attraction, etc.

[0100] Since the adjustment of the unit wall 210 and the folding blade 310 is not done in a stepwise manner, but may only involve fine-tuning or require stepless adjustment, an automatic locking element 520 is preferably provided in the position-adjustable transmission connection to achieve automatic control. This allows for automatic switching between locked and released states and is also suitable for stepless adjustment. For example, the automatic locking element 520 can be a locking cylinder 511 to lock or release the handle 340 and allow the handle 340 to slide and adjust.

[0101] To facilitate disassembly and assembly, and to maintain the relative position of the folding blade 310 and the second drive mechanism 320 before and after disassembly and assembly, a manual locking element 530 can also be provided in the locking mechanism 500. When in use, the manual locking element 530 remains engaged, and when disassembly is required, the engagement is disengaged to separate the parts. The manual locking element 530 preferably adopts a structure that allows for quick positioning and disassembly, such as a positioning pin or a snap-fit ​​method.

[0102] Combination Figure 11 , Figure 12 In one embodiment, in order to realize the above connection method and carry related components, the locking mechanism 500 includes a connecting 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 connecting seat 510 and the second drive mechanism 320, and the other acts between the connecting seat 510 and the folding knife 310.

[0103] In one embodiment, the second drive mechanism 320 is a push-pull cylinder 322, the output component 321 is a connecting seat fixed to the piston rod of the push-pull cylinder 322, and the manual locking component 530 acts between the connecting seat and the connecting seat 510. For example, the connecting seat and the connecting seat 510 are provided with mutually cooperating pin holes, and the manual locking component 530 is a positioning pin inserted into the corresponding pin hole. During disassembly, the connecting seat 510 and the second drive mechanism 320 can be quickly separated by the manual locking component 530. With the magnetic attraction 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, the bottom of the connecting seat 510 is provided with a first limiting hole 512, the handle 340 is inserted into the first limiting hole 512, and the automatic locking component 520 is a locking cylinder 511 installed in the connecting seat 510. The piston rod of the locking cylinder 511 has a limiting head 513 that interacts with the handle 340. In order to accommodate the adjustment and disassembly of the folding knife 310, the handle 340 is provided with a slot 341 with one end open. The piston cylinder of the locking cylinder 511 passes through the slot 341, and the limiting head 513 is located at the end of the piston cylinder that passes through the slot 341.

[0105] To provide additional support, the track 222 is extended and passes through the coupling seat 510. The passing 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, and the handle 340 can move to any position within the stroke range relative to the locking cylinder 511. After the unit wall 210 and the folding knife 310 are adjusted by the first drive mechanism 400, the locking cylinder 511 relocks the handle 340.

[0107] The adjustment direction of the unit wall 210 is restricted by the guide hole 120, and the arrangement direction of the guide seat 110 and the track 222 corresponds to it. For example, the extension direction of the guide hole 120 is the first direction, and the folding knife 310 moves along the second direction when it is working. 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, the locking mechanism 500 releases the locking of the handle 340 of the folding knife 310 and can then adjust accordingly without interference in the direction of movement.

[0108] In some cases, such as in 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 move directly because it moves relative to the second drive mechanism along the second direction, and there is interference in the direction of movement.

[0109] To solve this problem, see Figure 13 , Figure 14 In one embodiment, a sliding joint is provided between the locking mechanism 500 and the second driving mechanism, or within the locking mechanism 500, to engage in a third direction. The sliding joint can be configured such that the connecting seat 510 itself is a split structure with a sliding engagement, with one part of the split structure connected to the second driving mechanism 320 and the other part connected to the folding knife 310.

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

[0111] Based on the foregoing, one embodiment of this application also provides a bag-applying machine, incorporating the modular linkage adjustment mechanism for bag-applying machines described in the preceding embodiments. The structure of other parts of the bag-applying machine can be implemented in conjunction with existing technologies.

Combined with automatic control, scaling can be achieved, which can reduce the production and debugging of fixtures and further reduce costs.
