Description

[Technical Field]

[0001] This invention belongs to the field of automation equipment, and in particular relates to an automatic buckle pressing device for handles. [Background Technology]

[0002] In daily life, packaging bags used to hold heavy items are usually equipped with handles. These handles are generally fixed to the bag by snap fasteners. The handle consists of two interlocking buckles. During assembly, they are usually pressed together manually, positioned manually, or pressed together using a press machine, which is inefficient.

[0003] Currently, in order to achieve automated production, there are also devices that automatically press two handle buckles onto the packaging bag for assembly. However, the current level of automation of this equipment is not high. This is mainly because the packaging bag and handle buckles themselves are soft, which causes various deformations during the automatic pressing process. During automated bag loading or handling on automated equipment, jamming and insufficient processing precision are prone to occur, which increases the difficulty of full automation. [Summary of the Invention]

[0004] This invention provides an automatic buckle-pressing device for handles, which can automate the entire process from bag loading to buckling, greatly improving the degree of automation.

[0005] This invention is achieved through the following technical solution:

[0006] An automatic buckle fastening device for handles includes a frame, on which are provided:

[0007] A lateral transport mechanism, which is equipped with an adsorption belt for adsorbing and transporting the packaging bags laterally;

[0008] A pressing mechanism, located on the transverse transport mechanism, is used to press the handle fasteners onto the packaging bag;

[0009] The feeding mechanism is located on both sides of the pressing mechanism and is used to feed the handle fastener to the pressing mechanism;

[0010] The bag-loading mechanism is located on one side of the feeding mechanism;

[0011] The bag-taking mechanism, located on the transverse transport mechanism and opposite to the bag-loading mechanism, is used to transfer the packaging bags from the bag-loading mechanism to the transverse transport mechanism.

[0012] As described above, an automatic buckle fastening device for handles includes a bag-retrieving mechanism comprising a base, a bag-retrieving movable seat disposed on the base, and a bag-retrieving movable seat with:

[0013] The first bag-taking assembly can move relative to the bag-taking mechanism along with the bag-taking moving seat, and includes a left adsorption group and a right adsorption group, which can move relative to each other on the bag-taking moving seat.

[0014] The second bag-retrieving component is located below the first bag-retrieving component and can move relative to the upper bag mechanism along with the bag-retrieving moving seat. The second bag-retrieving component can move up and down on the bag-retrieving moving seat.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. This invention provides an automatic buckle pressing device for handles. After the packaging bag is loaded onto the bag loading mechanism, it is taken out by the bag picking mechanism and transported to the transverse transport mechanism. The transverse transport mechanism then transports the packaging bag to the pressing mechanism. The pressing mechanism presses the male and female buckles of the handle pressing parts on both sides of the feeding mechanism onto the packaging bag. After pressing, the transverse transport mechanism then transports the packaging bag out, thereby realizing the automation of packaging bag pressing and greatly improving efficiency.

[0017] 2. The present invention provides an automatic buckle pressing device for handles. Through the action of a first bag picking component and a second bag picking component, the first bag picking component can pull and smooth the adsorption position laterally, and the second bag picking component can pull and smooth the adsorption position vertically. This simulates the action of a human hand to smooth the area around the adsorption position of the packaging bag during transportation. This ensures that the adsorption position of the packaging bag is adjusted to a flat state before it is transported to the transportation mechanism, which facilitates accurate positioning. It also avoids the situation where the packaging bag develops wrinkles during the automatic pressing process, thus affecting the automatic pressing. [Attached Image Description]

Detailed Implementation Methods

[0024] To make the technical problems solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0025] This invention is achieved through the following technical solution:

[0026] like Figure 1 , Figure 2 As shown, an automatic handle buckle fastening device includes a frame 1, on which are provided: a horizontal transport mechanism 2, which has an adsorption belt 21 for adsorbing and transporting packaging bags horizontally; a pressing mechanism 12, located on the horizontal transport mechanism 2, for pressing the handle buckle 92 onto the packaging bag; a feeding mechanism 11, located on both sides of the pressing mechanism 12, for conveying the handle buckle 92 to the pressing mechanism 12; a bag loading mechanism 5, located on one side of the feeding mechanism 11; and a bag picking mechanism 3, located on the horizontal transport mechanism 2 and opposite to the bag loading mechanism 5, for transporting the packaging bag 9 at the bag loading mechanism 5 to the horizontal transport mechanism 2. This invention provides an automatic buckle fastening device for handles. After the packaging bag is loaded onto the bag loading mechanism, it is taken out by the bag picking mechanism and transported to the transverse transport mechanism. The transverse transport mechanism then transports the packaging bag to the pressing mechanism. The pressing mechanism presses the male and female buckles of the handle fasteners on both sides of the feeding mechanism onto the packaging bag. After fastening, the transverse transport mechanism then transports the packaging bag out, thereby automating the fastening of the packaging bag and greatly improving efficiency.

[0027] In this plan, such as Figures 3 to 8As shown, the specific structure of the bag-retrieving mechanism is as follows: it includes a base 3 and a bag-retrieving movable seat 301 disposed on the base 3. In this scheme, the base 3 is disposed on the frame 1, and the bag-retrieving movable seat 301 is slidably disposed on the base 3 for moving in the direction of the upper bag mechanism to realize the removal of a single packaging bag from the upper bag mechanism. However, as mentioned in the background art, when the packaging bags are suspended in a stacked manner, their surfaces are prone to unevenness. Based on this, in this embodiment of the invention, a first bag-retrieving component 31 disposed on the bag-retrieving movable seat 301 is also included, which can move with the bag-retrieving movable seat 301 in the direction of the upper bag mechanism. It includes a left adsorption group 311 and a right adsorption group 312, which can move relative to each other on the bag-retrieving movable seat 301. A second bag-retrieving component 32 is located below the first bag-retrieving component 31 and can move with the bag-retrieving movable seat 301 in the direction of the upper bag mechanism. The second bag-retrieving component 32 can move up and down relative to the bag-retrieving movable seat 301. During the movement of the first and second bag-picking components after adsorbing the packaging bag, the first bag-picking component can pull and smooth the adsorbed position laterally, and the second bag-picking component can pull and smooth the adsorbed position vertically. This simulates the action of smoothing the area around the adsorbed position of the packaging bag in a human-like manner, so as to ensure that the adsorbed position of the packaging bag is adjusted to a flat state before it is transported to the transport mechanism, so that the handle on it can be accurately positioned.

[0028] To further ensure the packaging bag remains flat after removal, the present invention also provides a bag removal method, comprising the following steps: S1, the first bag removal component 31 and the second bag removal component 32 adsorb the packaging bag 9 around the transport adsorption position, wherein the transport adsorption position is the location where the packaging bag is adsorbed by the transport adsorption position of the transport mechanism during transport; S2, the first bag removal component 31 and the second bag removal component 32 jointly pull the packaging bag 9 onto the transport mechanism, so that the adsorption component on the transport mechanism adsorbs the transport adsorption position of the packaging bag 9, and the packaging bag 9 arrives before the transport mechanism. The first bag-taking component 31 and the second bag-taking component 32 adjust the posture of the packaging bag 9. The posture adjustment includes a lateral smoothing action and an up-and-down smoothing action. The lateral smoothing action includes the left suction group 311 and the right suction group 312 of the first bag-taking component 31 moving away from each other after the first bag-taking component 31 adsorbs the packaging bag 9, so as to simulate a lateral pulling action around the transport suction position of the packaging bag 9. The up-and-down smoothing action includes the second bag-taking component 32 moving up and down after the second bag-taking component 32 adsorbs the packaging bag 9, so as to simulate an up-and-down pulling action around the transport suction position of the packaging bag 9. This method involves adjusting the posture of the transport adsorption position on the packaging bag during the process of the first and second bag-picking components moving the bag to the transport mechanism after adsorption. This is done in a manner similar to a human hand, smoothing the area around the transport adsorption position laterally and vertically. This ensures that the transport adsorption position is flat before the bag is transported to the transport mechanism, thereby guaranteeing the adsorption effect of the transport mechanism on the packaging bag and the positioning effect after adsorption. It also facilitates the accurate positioning of the handle and prevents wrinkles caused by unevenness of the surface.

[0029] Furthermore, such as Figure 4 As shown, in step S1, the first bag-taking assembly 31 adsorbs the packaging bag 9 on both sides above the transport adsorption position. Furthermore, in step S1, the second bag-taking assembly 32 adsorbs the packaging bag 9 below the transport adsorption position. This addresses the potential unevenness on the surface of the packaging bag. Figure 4 The posture of the curve position in the middle packaging bag, and after adjustment as follows: Figure 5 As shown, this method only needs to ensure that the transport adsorption position is flat to achieve accurate positioning on the automated equipment. Therefore, this method only needs to adsorb around the transport adsorption position. In this solution, the upper and lower sides of the transport adsorption position are adsorbed.

[0030] In addition, in order to accommodate packaging bags of different sizes, this solution also includes a third bag-taking component 33 in step S1. The third bag-taking component 33 is located at the second bag-taking component 32 and is used to adsorb the lower end or near the lower end of the packaging bag 9.

[0031] Furthermore, in step S2, the lateral smoothing action and the vertical smoothing action are performed simultaneously. That is, regardless of whether the orientation of the transport adsorption site is concave or convex, it is ensured to become flat by lateral and vertical pulling.

[0032] Specifically, in this embodiment of the invention, the first bag-taking component 31 is used to adsorb the upper part of the packaging bag transport adsorption position, and after adsorption, it moves laterally away from the left adsorption group 311 and the right adsorption group 312. Its specific structure is as follows: Figure 6 As shown, the system includes a first mounting plate 310 and a first lateral drive mechanism 313. The first mounting plate 310 is mounted on the bag-retrieving moving seat 301, and the first lateral drive mechanism 313 is mounted on the first mounting plate 310. The left adsorption group 311 and the right adsorption group 312 are mounted on the first lateral drive mechanism 313. This design simulates the action of a human hand flattening a recessed area by moving the left adsorption group 311 and the right adsorption group 312 laterally away from each other, so that the transport adsorption position is pulled laterally.

[0033] Further, in this embodiment of the invention, the left adsorption group 311 includes a left mounting plate 3110 and a left suction head 3111 disposed on the left mounting plate 3110, and the right adsorption group 312 includes a right mounting plate 3120 and a right suction head 3121 disposed on the right mounting plate 3120. The first lateral drive mechanism 313 may be a cylinder, which drives the left mounting plate 3110 and the right mounting plate 3120 to move relative to each other simultaneously to complete the above-mentioned actions.

[0034] In addition, in this embodiment of the invention, both the left suction head 3111 and the right suction head 3121 are provided in duplicate. This allows them to adsorb more dots on the packaging bag, thereby preventing detachment.

[0035] Furthermore, to facilitate adjustable adsorption position, in this embodiment of the invention, the left mounting plate 3110 is provided with an elongated adjustment hole extending vertically, and the left suction head 3111 is fixed within the adjustment hole. This allows it to be used with packaging bags of different sizes, thereby greatly improving the applicability of this product.

[0036] To simplify the structure, an elastic reset member is provided between the left mounting plate 3110 and the right mounting plate 3120. After the first lateral drive mechanism 313 releases force, this elastic reset member allows the left mounting plate 3110 and the right mounting plate 3120 to quickly move away from each other. The elastic force of the selected reset member is matched to the suction force of its nozzle to achieve the aforementioned effect. Its simple structure allows for a more streamlined overall machine design.

[0037] In this embodiment of the invention, the second bag-taking component 32 is mainly used for pulling the packaging bag up and down. Its specific structure includes a positioning tail seat 321, a positioning plate 322, a guide rod 323, a second suction head group 324, and an up and down driving mechanism 325.

[0038] The positioning tailstock 321 is mounted on the bag-retrieving moving seat 301, and the positioning tailstock 321 has a vertically extending strip hole 3211; the positioning plate 322 is fixedly installed, and the positioning plate 322 has a vertically extending clearance hole 3221; the second suction head assembly 324 is mounted on the end of the guide rod 323; the guide rod 323 passes through the clearance hole 3221 of the positioning plate 322, and its tail end passes through the strip hole 3211 of the positioning tailstock 321; the up-and-down driving mechanism is mounted on the positioning plate 322 and is used to drive the guide rod 323 and the second suction head assembly 324 to move up and down. Its principle is that after the second suction head assembly 324 adsorbs the packaging bag, the up-and-down driving mechanism 325 drives the second suction head assembly 324 to move up and down, thereby realizing the action of pulling the packaging bag up and down.

[0039] More specifically, the second suction head assembly 324 includes multiple suction heads, with three provided in this design, connected to the guide rod 323 via a connecting seat. Furthermore, in this design, the guide rod 323 is positioned opposite the central suction head, and a second guide rod is also provided on one side of the suction head, which increases the stability of the second suction head assembly 324 during longitudinal and vertical movement.

[0040] In addition, since the position of the packaging bag changes during the bag-picking process when the bag-picking mechanism picks up the packaging bag from the bag-picking mechanism, in order to ensure that the second bag-picking component can smoothly contact the surface of the packaging bag for easy adsorption, the guide rod 323 is provided with a limiting piece near its tail end with an outer diameter larger than that of the strip hole 3211. A return spring is also provided between the limiting piece and the positioning tail seat 321. Thus, when the bag-picking moving seat 301 moves the second bag-picking component toward the packaging bag, and the second bag-picking component contacts the packaging bag, the return spring causes the bag-picking moving seat 301 to continue moving. During this process, the second bag-picking component is limited by the packaging bag and becomes a tail-end compression spring. This spring then keeps the second bag-picking component pressing against the surface of the packaging bag.

[0041] In addition, in order to ensure that the lower end is not affected when taking out larger packaging bags, the bag taking mechanism also includes a third bag taking component 33 disposed on the bag taking moving seat 301, and the third bag taking component 33 is located below the second bag taking component 32.

[0042] Specifically, the third bag-removing assembly 33 has a similar structure to the first bag-removing assembly, including a third mounting plate 331, a connecting plate 332 disposed on the third mounting plate 331, and a plurality of suction heads 333 disposed on the connecting plate 332.

[0043] Furthermore, for ease of adjustment, the connecting plate 332 is provided with multiple horizontally extending adjustment holes, and the suction head 333 is fixed in the adjustment holes, so that it can be appropriately adjusted according to different sizes of packaging bags to ensure the adsorption effect.

[0044] In this embodiment of the invention, in order to achieve non-stop operation when replenishing new handle fastener material, an alternating feeding component is also provided on the feeding mechanism 11, such as... Figures 14 to 20 As shown, it includes a first pushing assembly 41 disposed on one side of the feeding mechanism 11 and movable along the feeding mechanism 11, and a second pushing assembly 42 disposed on the other side of the feeding mechanism 11 and movable along the feeding mechanism 11; the first pushing assembly 41 includes a first pushing moving seat 411 and a first pushing plate 412 hinged to the first pushing moving seat 411; the second pushing assembly 42 includes a second pushing moving seat 421 and a second pushing plate hinged to the second pushing moving seat 421. Plate 422; The first pusher moving seat 411 and the second pusher moving seat 421 are each connected to opposite sides of the feeding mechanism 11. The first pusher plate 412 and the second pusher plate 422 are both located inside the feeding mechanism 11. The first pusher plate 412 can rotate relative to the first pusher moving seat 411 to fold outward from the feeding mechanism 11. After the first pusher plate 412 folds outward, the second pusher plate 422 can move past the first pusher assembly 41 within the feeding mechanism 11. By moving the first pusher assembly along the feeding mechanism, the first pusher assembly can always maintain a pushing force on the handle buckle. Moreover, the first pusher assembly and the second pusher assembly are set on the same feeding mechanism for alternating use, so that they can be accurately pushed to the pressing station, thereby realizing material replenishment without stopping the machine and greatly improving efficiency.

[0045] like Figure 15 As shown, after the first feeding, the second pushing component 42 continues to push the material 92 to the pressing station, while the first pushing component 41 is still in the starting position, as... Figure 19 As shown, when materials need to be replenished, the materials can be placed directly in the feeding mechanism and located behind the second pushing component 42 and between the first pushing component 41. At this time, the second pushing component 42 can maintain the pushing and pressing of the material in front, and the front pressing station works normally. Figure 17 As shown, the first pushing component 41 is pushed to the end of the newly added material, which then pushes the newly added material to the second pushing component 42. At this time, the pushing plate of the second pushing component 42 is flipped outward to make room, thus completing the material docking. Figure 18 As shown, the second pushing component 42 can pass over the first pushing component 41 and return to the starting end of the feeding mechanism. By repeating the above process, materials can be added alternately without stopping the machine, thereby greatly improving efficiency.

[0046] In this design, the first pusher plate 412 includes a first hinge seat 4121 and a first pusher plate 4122 connected to the first hinge seat 4121. The first hinge seat 4121 is also provided with a handle 4123. Its structure is simple and convenient for operators to manually flip the first pusher plate 4122 outward to make room.

[0047] In this embodiment of the invention, the first pusher moving seat 411 is L-shaped, the first hinge seat 4121 is hinged to the upper side of the first pusher moving seat 411, the first push plate 4122 falls into the feeding mechanism 11 from the upper opening of the feeding mechanism 11, and the first hinge seat 4121 drives the first push plate 4122 to fold upward toward the first pusher moving seat 411 so that the first push plate 4122 folds outward to make room.

[0048] In this invention, such as Figure 19 As shown, the feeding drive assembly includes a first feeding drive member 491 and a first feeding transmission member 4911 disposed on the feeding mechanism 11 facing the first pushing assembly 41, a second feeding drive member 492 and a second feeding transmission member 4921 disposed on the feeding mechanism 11 facing the second pushing assembly 42. The first feeding transmission member 4911 is connected between the first feeding drive member 491 and the first pushing assembly 41, and the second feeding transmission member 4921 is connected between the second feeding drive member 492 and the second pushing assembly 42. The feeding drive assembly employs dual feeding drive members, enabling automated reciprocating motion of the first pushing assembly and the second pushing assembly.

[0049] In this embodiment of the invention, a fixed bracket 111 is provided at the bottom of the feeding mechanism 11, and the first feeding drive 491 and the second feeding drive 492 are both mounted on the fixed bracket 111. Its structure is simple, facilitating the installation of the dual feeding drive components. Furthermore, the output ends of the first feeding drive 491 and the second feeding drive 492 extend out to both sides of the feeding mechanism 11, respectively, and are connected to the first feeding transmission component 4911 and the second feeding transmission component 4921 for transmission.

[0050] Specifically, the feeding mechanism 11 is provided with a slide rail along the feeding direction, and the pushing moving seat 411 is provided with a sliding seat that cooperates with the slide rail. Its structure is simple and facilitates the movement of the pushing moving seat 411. The first feeding drive 491 drives the sliding seat to reciprocate through the first feeding transmission 4911, thereby automating the first pushing assembly 41. In this solution, the first feeding drive 491 can be a motor, and the first feeding transmission 4911 is a transmission chain, transmission belt, or transmission rope structure that cooperates with the motor. The motor drives the transmission structure, causing the sliding seat to slide back and forth on the slide rail, thereby realizing the feeding and resetting of the first feeding drive 491. Similarly, the second feeding drive 492 and the second feeding transmission 4921 also drive the second pushing assembly 42 to feed and reset.

[0051] In this embodiment of the invention, to ensure that the packaging bag does not easily shift position during the bag-loading process, for example... Figures 9 to 10 As shown, one side of the transverse transport mechanism 2 is a bag-picking station. The bag-picking adjustment component 6 is located at the bag-picking station and includes a left adjustment component 61 and a right adjustment component 62. The left adjustment component 61 and the right adjustment component 62 form a guide channel with an opening that gradually decreases from the upper bag mechanism 5 to the bag-picking station. A bag-picking adjustment component is added to the side of the transverse transport mechanism opposite to the upper bag mechanism. This creates a funnel-shaped guide channel, allowing the packaging bags on the upper bag mechanism to be pre-positioned through this channel. This facilitates the bag-picking mechanism from moving in and picking up the bags, reducing the need for machine stops and adjustments due to bag position shifts. Furthermore, in this solution, through the cooperation of the bag-picking mechanism and the transverse transport mechanism, after the bag-picking mechanism adsorbs the packaging bag, the bag adheres to the adsorption belt during the resetting process, allowing the bag to be adsorbed by the adsorption belt and thus move with the transverse transport mechanism to the next station.

[0052] Specifically, in this solution, the aforementioned guide channel is formed by the left adjusting member 61 and the right adjusting member 62. The specific structure is as follows: the left adjusting member 61 includes at least a left guide plate 611, and the right adjusting member 62 includes at least a right guide plate 621. The left guide plate 611 and the right guide plate 621 are provided with oppositely arranged straight guide portions for forming equidistant channels, and both the left guide plate 611 and the right guide plate 621 have oblique guide portions on the side facing the upper bag mechanism 5. Its structure is simple and can facilitate pre-alignment of the packaging bag before handling.

[0053] Furthermore, in this embodiment of the invention, for ease of adjustment, the left adjusting member 61 further includes an adjusting drive mechanism 612 for driving the left guide plate 611 to move relative to the right guide plate 621. Additionally, the adjusting drive mechanism 612 is a motor. Thus, the distance between the left guide plate 611 and the right guide plate 621 can be adjusted via the drive mechanism, allowing it to be used with packaging bags of different widths.

[0054] In this embodiment of the invention, the right guide plate 621 is movably mounted on the transverse transport mechanism 2. Unlike the above, this allows for the simultaneous movement of the left guide plate 611 and the right guide plate 621, making the center position of the guide channel essentially unaffected. This facilitates bag retrieval in conjunction with the linearly moving bag-retrieving mechanism. Alternatively, either guide plate can be adjusted individually to accommodate eccentric packaging bag shapes.

[0055] In this embodiment of the invention, to prevent subsequent bags from shifting and causing positional deviations when the bag-picking mechanism 3 picks up a bag, the bag-picking adjustment component 6 further includes a stop mechanism. In this solution, the stop mechanism includes a left stop 691 located on the left guide plate 611 and extending to the right, and a right stop 692 located on the right guide plate 621 and extending to the left. This means that the left and right stops 691 and 692 extend into the path of the upper bag. Because the bag itself is relatively soft, the frontmost bag, when attracted by the bag-picking mechanism 3, can pass over the left and right stops 691 and 692, while all subsequent bags are blocked by the left and right stops 691 and 692, thereby effectively preventing the bags from shifting due to being attracted by the feeding bags.

[0056] Of course, in this solution, to prevent the left stop 691 and right stop 692 from excessively obstructing the bag feeding, especially during high-speed bag feeding, the stop mechanism also includes a stop drive 693 for driving the left stop 691 and right stop 692 to rotate. This allows the left stop 691 and right stop 692 to rotate after the bag-picking mechanism 3 has absorbed the foremost bag, preventing it from being between the left guide plate 611 and right guide plate 621. After the bag-picking mechanism 3 removes the bag, the left stop 691 and right stop 692 return to their original positions. This ensures that even if subsequent bags shift with the feeding bags, the resetting of the left stop 691 and right stop 692 can still adjust the position of the foremost bag.

[0057] In embodiments of the present invention, such as Figures 11 to 13 As shown, the frame 1 is also equipped with an anti-rolling guiding mechanism, which is located at the bag-picking station. The anti-rolling guiding mechanism includes a guide fixing frame 71, a movable frame 72 movably mounted on the guide fixing frame 71, and a guide drive component 73 mounted on the guide fixing frame 71 and connected to the movable frame 72. The guide drive component 73 drives the movable frame 72 to reciprocate along the bag transport direction. The movable frame 72 is provided with at least a limiting groove 721 for the upper edge of the bag to be inserted. The opposite side walls of the limiting groove 721 prevent the upper corner of the bag from folding towards the snap-fit ​​hole. With the addition of the guide fixing frame and the movable frame, when the bag-picking mechanism attaches the bag to the transverse transport mechanism, the upper edge of the bag is inserted into the limiting groove of the movable frame. Thus, when the transverse transport mechanism moves the bag at high speed, even if the upper corner of the bag is blown up by wind resistance and rolls up, it will be blocked by the opposite side walls of the limiting groove, thereby achieving the function of limiting and preventing roll-up.

[0058] In addition, in order to coordinate with the travel of the packaging bag and make way for the packaging bag buckle, the movable frame is driven by the guide drive to move laterally with the packaging bag, and after the packaging bag is in place at the buckle station, the movable frame is driven to reset.

[0059] In this embodiment of the invention, the limiting groove 721 is an elongated groove with its opening facing downwards. Since the packaging bag itself is soft, during the process of being adsorbed by the bag-taking mechanism 3 and transferred to the transverse transport mechanism 2, its upper edge is automatically blocked by the movable frame 72 and bends over the movable frame 72 to enter the limiting groove 721, and then resets under its own elasticity to be embedded in the limiting groove 721.

[0060] In this design, to facilitate the reciprocating motion of the movable frame 72, the guide fixing frame 71 is provided with a slide rail, and the limiting groove 721 is connected to the slide rail through a sliding seat.

[0061] Furthermore, the guide drive component 73 is installed on the rear side of the guide fixing frame 71 and connected to the rear side of the movable frame 72. Specifically, the guide drive component 73 is a cylinder. Its structure is simple and can ensure that during the process of the packaging bag moving from the bag picking station of the transverse transport mechanism 2 to the snap-fit ​​station, the limiting groove remains on the periphery of the upper edge of the packaging bag to prevent the upper edge corner of the packaging bag from rolling up during the movement. Moreover, it can be reset during snap-fit, ensuring the snap-fit ​​operation.

[0062] In addition, in this solution, the guide fixing frame 71 is also provided with a bag blocking structure 74. The bag blocking structure 74 is located on the front side of the guide fixing frame 71 and in the direction in which the packaging bag enters the movable frame 72. It can block the packaging bag and the packaging bag on the front side of the guide fixing frame 71 during the process of the bag picking mechanism 3 adsorbing and transferring the packaging bag to the transverse transport mechanism 2.

[0063] In this embodiment of the invention, the bag-blocking structure 74 includes two vertically arranged baffles 741, which are spaced apart. In this way, during the process of the bag-picking mechanism 3 adsorbing and transferring the packaging bag, the packaging bag will be blocked by the two baffles 741 and deformed to pass over the two baffles. During this process, the packaging bag can be paginated to prevent the adjacent bags from following due to the speed of the suctioned bag, thereby improving the reliability of bag picking.

[0064] In embodiments of the present invention, such as Figures 21 to 28 As shown, the specific structure of the upper bag mechanism is as follows: it includes an upper bag frame 51 and a hanging rod group 501 that is set on the upper bag frame 51 and extends horizontally. The hanging rod group 501 includes a load-bearing hanging rod 52 and a positioning hanging rod 53. The load-bearing hanging rod 52 and the positioning hanging rod 53 are arranged horizontally side by side.

[0065] The load-bearing hanging rod 52 has a rod head 521 at its end in the material-picking direction. The rod head 521 is used to limit the lateral movement of the packaging bag. The positioning hanging rod 53 has a guide head 531 at its end in the material-picking direction. The guide head 531 is located below the rod head 521 and cooperates with the upper end face of the rod head 521 to limit the longitudinal movement of the packaging bag. This invention provides a bag-loading mechanism applied to a snap-locking machine. Through the combination of the load-bearing hanging rod and the positioning hanging rod, rod heads and guide heads are respectively set at the ends of the load-bearing hanging rod and the positioning hanging rod. The lateral movement of the packaging bag is limited by the contact between the two sides of the rod head and the two sides inside the handle position of the packaging bag. The longitudinal movement of the packaging bag is limited by the cooperation between the lower end face of the guide head and the upper end face of the rod head. This allows the position of the packaging bag that has moved along the load-bearing hanging rod to the end to be oriented, thereby facilitating more accurate positioning and picking up of the packaging bag by the bag-picking mechanism, so as to facilitate more accurate positioning of the packaging bag in the subsequent snap-locking process.

[0066] In this embodiment of the invention, to improve the stability of the load-bearing hanging rod 52, the load-bearing hanging rod 52 includes two sets, which are arranged parallel to each other on both sides of the positioning hanging rod 53. This is equivalent to the two load-bearing hanging rods 52 being symmetrically arranged on both sides of the positioning hanging rod 53, which increases the contact surface for suspension, making it less likely for the packaging bag to shift on the hanging rod.

[0067] In this embodiment of the invention, the guide head 531 is plate-shaped and located below the rod head 521. Specifically, the guide head 531 is a U-shaped support plate. As mentioned above, the guide head 531 is mainly used to thicken the lower side of the rod head, so that when the packaging bag moves to the guide head, the lower side of the guide head and the upper surface of the rod head together limit the gap of the packaging bag's vertical movement. This solution, through the structure of the U-shaped support plate, allows it to fit the bottom of the packaging bag's handle while greatly reducing its own weight.

[0068] In addition, in this solution, the front side of the guide head 531 has an outlet part 5311 that is inclined toward the rod head 521, and the front end of the rod head is also arc-shaped. Its front end is connected to the bag picking mechanism, so it is set to be inclined to facilitate the bag being exported from the hanging rod.

[0069] Furthermore, in this design, the upper surface of the load-bearing hanging rod 52 is higher than the positioning hanging rod 53. This allows the load-bearing capacity of the packaging bag to be distributed among the load-bearing hanging rods 52.

[0070] In this design, the lower end of the positioning rod 53 is provided with a rod connecting block 532, which extends to both sides and connects to the bottom of the load-bearing rods 52 on both sides. Its structure is simple and easy to connect, making the rod assembly more stable overall.

[0071] In this design, the load-bearing hanging rods 52 on both sides can be adjusted in position on the connecting block 532 to adjust the distance between the two load-bearing hanging rods 52. This allows the distance between the two load-bearing hanging rods 52 to be adjusted according to the size of the handle of different sized packaging bags, and also ensures that the rod heads can be laterally limited for packaging bags of different sized sizes.

[0072] To facilitate bag loading, in this embodiment of the invention, the bag loading frame 51 is also provided with a bag loading pusher 7 that can move along the feeding direction. The bag loading pusher 7 causes the packaging bags on the hanging rod to gradually move closer to the bag picking mechanism.

[0073] Specifically, in this solution, the upper bag pusher 7 passes through the hanging rod assembly 501 and can move along the hanging rod assembly 501. Moreover, the upper bag pusher 7 includes an upper bag pusher plate 71 and an upper bag moving assembly. The upper bag pusher plate 71 is connected to the upper bag frame 51 through the upper bag moving assembly, and the upper bag pusher plate 71 has outwardly extending side wings 711 on both sides.

[0074] Furthermore, in this embodiment of the invention, one end of the hanging rod assembly 501 is hinged to the upper bag frame 51, and the other end of the hanging rod assembly 501 opposite to the hinged end is the upper bag end. The upper bag frame 51 is also provided with a height adjustment component for fixing the hinged end of the hanging rod assembly 501. By hinged to the upper bag frame, the height of the upper bag end can be changed by rotating the hanging rod assembly along the hinged end. Then, by fixing the hinged end of the hanging rod assembly with the height adjustment component, the position of the upper bag end can be adjusted according to the packaging bags of different sizes. Its structure is simple and convenient for adjustment, greatly improving the overall efficiency of the equipment.

[0075] In this embodiment of the invention, the hanging rod assembly 501 is fixed on the bearing seat 502, and the upper bag frame 51 is provided with an upper positioning plate 511. The height adjustment component passes through the positioning plate 511 and is connected to the bearing seat 502. The height adjustment component can change the angle of the bearing seat 502 relative to the upper bag frame 51 to change the height of the upper bag end. The hanging rod assembly 501 is hinged to the upper bag frame 51 as a whole through the bearing seat 502, so when adjusting the height of the upper bag end, it is only necessary to rotate the bearing seat relative to the upper bag frame. Its structure is simple, making the adjustment operation more convenient.

[0076] like Figure 25 As shown, the hanging rod assembly 501 is currently in a horizontal position. When the hanging rod assembly 501 rotates counterclockwise, the height of its upper bag end increases, as shown... Figure 26 As shown. When the hanging rod assembly 501 rotates clockwise, the height of its upper bag end decreases, as... Figure 27 As shown.

[0077] In embodiments of the present invention, such as Figure 28As shown, the upper bag frame 51 has the following specific structure: it includes a vertically arranged column 512 and a horizontally arranged crossbeam 513. The crossbeam 513 is located above the column 512, and the positioning plate 511 is arranged on the crossbeam 513. In this design, the main function of the upper bag frame 51 is to support the hanging rod assembly 501. Additionally, the bearing seat 502 has insertion holes penetrating its upper and lower end faces. The upper end of the column 512 has a hinged insert 5121, which passes through the insertion holes and is hinged to the bearing seat 502. By hinged between the bearing seat 502 and the hinged insert 5121, the column serves as an important component supporting the hanging rod assembly, with a simple structure and sufficient strength.

[0078] Specifically, in this design, when the hinged plug 5121 is inserted into the socket, a gap is left between the hinged plug 5121 and the two side walls along the length of the socket. This facilitates the rotation of the bearing seat 502 relative to the hinge.

[0079] Furthermore, in this embodiment of the invention, the height adjustment assembly is used to fix the hinge seat, and its specific structure includes an adjusting rod 81 that passes through the upper positioning plate 511 and extends to the bearing seat 502, and an adjusting member 82 disposed on the adjusting rod 81 for fixing the bearing seat 502. Its structure is simple and easy to adjust. Moreover, in this solution, the adjusting rod 81 is a bolt, and the adjusting member 82 is a nut.
