Description
Technical Field
[0001] This utility model relates to the technical field of packaging bag making equipment, and in particular to a card placement device for bag making equipment. This card placement device can be used in bag making equipment. Background Technology
[0002] Due to their high practicality and portability, packaging bags have become an indispensable tool in modern society, and people's requirements for their manufacture have gradually diversified. For example, some users want packaging bags to be as lightweight and easy to fold as possible, while others want tote bags to be as sturdy as possible and not easily deformed. Based on this, packaging bags have undergone various improvements in terms of shape, material selection, and handle fixing.
[0003] Among these, the bag opening is a very vulnerable part. Furthermore, the handles of packaging bags are usually located at the bag opening and are often fixed to the edge of the opening by adhesive or fasteners. To improve the strength of the bag opening and its connection with the handle, a card is usually attached to the bag opening during the packaging bag production process. Sometimes, a pair of cards are even placed on the inner walls of both sides of the bag opening; one card is used to reinforce the connection between the bag body and the handle, while the other is only used to improve the strength of the bag opening.
[0004] However, existing bag-making equipment can usually only reinforce a single card on the substrate. If multiple cards are installed, the card gripping and storage structures need to be significantly modified. Furthermore, when multiple cards are transferred simultaneously, the space required for the transfer process is large, which is not only detrimental to the design of other nearby components, but also makes the cards prone to interference from nearby components, causing them to fall off or shift, which seriously reduces the yield of the packaging bags. Utility Model Content
[0005] The purpose of this invention is to solve the technical problems of existing bag-making equipment that can only reinforce a single card on the substrate. When installing multiple cards, the card gripping and storage structures need to be significantly modified. Furthermore, when transferring multiple cards simultaneously, the space required for the transfer process is large, which is not only unfavorable to the design of other nearby components, but also makes the cards prone to interference from nearby components, causing them to fall off or shift, thus seriously reducing the yield of the packaging bags.
[0006] To solve the above-mentioned technical problems, the present invention discloses a card placement device for a bag making equipment. The card placement device includes multiple card placement components, each corresponding to a specific card attaching station of the bag making equipment.
[0007] The card placement component is located next to the corresponding card-attaching station and includes a card storage component and a card transfer component. Multiple cards are stacked and stored in the card storage component, and the gripping end of the card transfer component can move between the card storage component and the corresponding card-attaching station.
[0008] Furthermore, the substrate placed on the transport component of the bag making equipment is conveyed to a card-attaching station. The gripping end of the card transfer component grabs a single card from the card storage component and transfers the card to the corresponding bonding area of the substrate located at the card-attaching station.
[0009] By adopting the above technical solution, and setting up multiple card placement components corresponding to multiple card-applying stations, it is possible to perform card-applying operations on both sides or multiple positions of the packaging bag opening for different functions. The card transfer component corresponding to each card-applying station can move precisely between the card storage component and the corresponding card-applying station, achieving stable gripping, precise transfer, and applicability of a single card, ensuring the accuracy of the card's applicability on the substrate. Furthermore, the independent setup of multiple card placement components, each corresponding to a card-applying station, reduces the difficulty and cost of modifying the bag-making equipment, while improving its versatility. It can flexibly adapt to the applicability requirements of single, double, or multiple cards, and accommodate diverse bag-making processes.
[0010] In addition, compared with the existing technology that simultaneously transfers multiple cards at one workstation, this method significantly reduces the space required for card transfer at a single card-attaching workstation, avoids the limitations imposed on the design of surrounding components by excessive transfer space, and avoids the problem of card interference with surrounding components during card transfer, which could lead to card detachment or displacement. This significantly improves the stability and reliability of card mounting.
[0011] The present invention also discloses a card placement device for a bag making equipment. The card storage component is located on the side of the card transfer component away from the corresponding card pasting station. The gripping end of the card transfer component grips the card from the card outlet of the card storage component, and the card outlet of the card storage component is higher than the card pasting station in the vertical direction.
[0012] Furthermore, the card transfer component includes a rotating shaft located below the card outlet, a gripping end located on the rotating shaft and aligned vertically with the card outlet, and a transfer drive component that drives the rotating shaft to rotate, thereby linking the gripping end to move between the card storage component and the card attaching station.
[0013] By adopting the above technical solution, the card storage component is located on the side of the card transfer component away from the corresponding card-applying station, which reduces the risk of interference between the card storage component and the substrate and the component transporting the substrate. In addition, the card outlet on the card storage component is higher than the card-applying station in the vertical direction. When the gripping end of the transfer drive component picks up the card from the card outlet, there is no interference from other components around it, which is conducive to accurate gripping and avoids the problems of card offset, skew, or missed gripping when picking up the card.
[0014] Furthermore, the card transfer component rotates via a pivot located below the card outlet, which in turn moves the gripping end. This allows for precise control of the gripping end's trajectory, ensuring smooth movement between the card storage component and the card-attaching station. It features a simple structure and stable transmission, reducing the risk of mechanical failure and maintenance costs of the card placement device.
[0015] The present invention also discloses a card placement device for a bag making equipment. The card placement component further includes a mounting base, which is disposed on the frame of the bag making equipment and located next to the card pasting station.
[0016] The transfer drive component is configured as a transfer drive motor, which is fixed on the mounting base, and its output end is connected to one end of the rotating shaft for transmission, driving the rotating shaft to rotate relative to the mounting base. Furthermore, the card transfer component includes a support member located at the axial center of the rotating shaft and extending radially outward along the shaft. Multiple adsorption members are spaced apart on one side of the support member, with the adsorption head of each adsorption member facing the card outlet as a gripping end.
[0017] By adopting the above technical solution, the card placement component is stably installed through the mounting base, ensuring that there is no shaking or displacement during the card grabbing and transfer process, and providing a stable installation foundation for subsequent accurate card retrieval and card placement.
[0018] Furthermore, the transfer drive motor boasts high transmission precision and fast response speed, enabling precise control of the shaft's rotation angle and speed. This, in turn, allows for precise control of the gripping end's movement trajectory and start / stop time, ensuring the accuracy and stability of card gripping and transfer. Multiple adsorption components located on the support structure firmly grip individual cards through adsorption force, preventing cards from falling off or tilting during gripping and transfer. The spacing between these adsorption components also accommodates cards of different sizes, improving the applicability of the card placement device.
[0019] The present invention also discloses a card placement device for a bag making equipment, wherein each adsorption component is a suction cup, and the card placement assembly further includes a pressing drive component that is connected to the suction cup for transmission.
[0020] The pressing drive component is located on the other side of the support member, is connected to the gripping end in a transmission manner, and can drive the gripping end to move relative to the support member.
[0021] By adopting the above technical solution, the pressing drive component can drive the gripping end (suction cup) to move relative to the support component and the rotating shaft, flexibly adjusting the posture and position of the gripping end to adapt to the card exit height of the card storage component and the substrate bonding area position of the card pasting station, further improving the smoothness and accuracy of card picking and placing; and after the card is transferred to the preset bonding area of the substrate, the pressing drive component can drive the support component and the suction cup to press down synchronously, pressing the card tightly onto the pre-coated bonding area, so that the adhesive layer between the card and the substrate is fully bonded, significantly strengthening the connection strength of the card on the substrate, avoiding the problem of the card not being firmly bonded and falling off later, further improving the reinforcement effect of the packaging bag opening and the stability of the product structure.
[0022] The present invention also discloses a card placement device for a bag making equipment, wherein multiple cards are stacked and stored in the receiving slot of a card storage component, and the card storage component has an open card outlet at the end near the card pasting station in the card stacking direction.
[0023] The gripping end of the card transfer component grips the outer wall of the card near the card exit and pulls it out from the card exit.
[0024] Using the above technical solution, the receiving slot can limit the stacked cards, preventing them from scattering or tilting during storage and ensuring that all cards maintain a neat stacked posture, facilitating accurate card grabbing by the gripping end. Furthermore, the gripping end grasps the outer wall of the card near the exit and pulls it out from the card exit, enabling smooth grabbing of single cards and preventing multiple cards from sticking together during the grabbing process. At the same time, the method of grasping the outer wall does not damage the card itself, ensuring card integrity.
[0025] The present invention also discloses a card placement device for a bag making equipment, wherein the receiving groove extends downward from the top at an angle relative to the vertical direction toward the card pasting station, and the end of the receiving groove near the card pasting station is open to form a card outlet.
[0026] Furthermore, the inclination angle of the receiving groove relative to the vertical direction is in the range of 30° to 60°.
[0027] By employing the above technical solution, the tilted receiving slot utilizes the cards' own weight to ensure that stacked cards always align and converge towards the card exit direction. This guarantees that cards near the exit are always in the preset gripping position, preventing cards from getting stuck or misaligned within the receiving slot, thus further improving the smoothness and success rate of card retrieval. Furthermore, limiting the tilt angle to the range of 30° to 60° ensures both smooth card feeding and stable card storage. An angle that is too large (e.g., greater than 60°) can cause cards to slip too quickly and become scattered, while an angle that is too small (e.g., less than 30°) cannot fully utilize gravity to bring the cards together.
[0028] The present invention also discloses a card placement device for a bag making equipment. The card storage component further includes a blocking member, which is disposed at the card outlet and located at both ends of the receiving groove in the length direction of the card.
[0029] In this configuration, the outer wall of the card closest to the card outlet in the receiving slot abuts against the blocking element.
[0030] By adopting the above technical solution, the blocking component can prevent stacked cards from sliding off the outlet on their own, and can achieve precise positioning to prevent cards from sliding off too quickly and stacking up haphazardly, thus ensuring the stability of card storage.
[0031] The present invention also discloses a card placement device for a bag making equipment. The blocking component includes a pair of baffles spaced apart along the length of the card. The pair of baffles are respectively fixedly installed on the ends of the two side walls of the receiving groove and extend toward each other. The outer walls of the two ends of the card closest to the card outlet in the receiving groove respectively abut against the pair of baffles.
[0032] Using the above technical solution, a pair of baffles extend toward each other and are fixed to the end of the side wall of the receiving groove. The structure is compact and does not occupy the outer wall surface of the card that is being gripped. That is, it does not interfere with the gripping action of the gripping end on the outer wall of the card. At the same time, the pair of baffles only abut against the outer walls at both ends of the card, without damaging the card surface and ensuring the integrity of the card.
[0033] The present invention also discloses a card placement device for a bag making equipment. The card storage component further includes multiple auxiliary limiting rods. The multiple auxiliary limiting rods are spaced apart along the length direction of the card on the open side of the receiving groove. The lower end of each auxiliary limiting rod extends toward the card outlet and abuts against the edge of the card closest to the card outlet in the receiving groove.
[0034] Using the above technical solution, multiple spaced auxiliary limiting rods can precisely limit the card closest to the exit from the open side of the receiving slot. Combined with the end limiting of the baffles on both sides, this prevents the card from shifting or warping in the width direction, ensuring that the card always maintains a flat and regular posture, further improving the accuracy of card retrieval and avoiding problems such as unstable gripping or missed grabbing due to card warping or shifting. Furthermore, the lower end of the auxiliary limiting rod extends towards the card exit and abuts against the edge of the card, neither obstructing the gripping space at the card exit nor interfering with the gripping action of the gripping end on the outer wall of the card. At the same time, it can also prevent the card from sliding off the open side of the receiving slot under the action of gravity, further improving the success rate of card retrieval.
[0035] The present invention also discloses a bag-making device, including a frame, a transport component, and a card placement device for any of the above-mentioned bag-making devices.
[0036] The bag-making equipment includes two pairs of card-applying stations set on the bag-making path. The two pairs of card-applying stations are arranged sequentially along the bag-making path, and each pair of card-applying stations is set on both sides of the transport component. Each card-applying station is equipped with a corresponding card placement component on its side.
[0037] Alternatively, the bag making equipment includes at least one pair of card-applying stations arranged along the bag making path, with each pair of card-applying stations arranged sequentially along the bag making path, and each card-applying station having a corresponding card placement component on its side.
[0038] Using the above technical solution, the transport components of this bag-making equipment can continuously convey the substrate along the bag-making path. In conjunction with the card-applying stations and corresponding card placement components arranged sequentially along the bag-making path, the corresponding card-applying operation can be achieved by using the card placement components corresponding to each pair of card-applying stations. Furthermore, this bag-making equipment can flexibly adjust the number and arrangement of card-applying stations according to the card-applying requirements of the packaging bags (single or double-sided, single or multiple sheets), adapting to the production of packaging bags of different specifications and with different reinforcement requirements, greatly improving the versatility and adaptability of the bag-making equipment.
[0039] The beneficial effects of this utility model are as follows:
[0040] This utility model discloses a card placement device for a bag-making equipment. The card placement device includes multiple card placement components, each corresponding to a specific card-applying station on the bag-making equipment. Each card placement component is located beside its respective card-applying station and includes a card storage component and a card transfer component. Multiple cards are stacked and stored within the card storage component. Substrate placed on a transport component of the bag-making equipment is transported to a card-applying station. The gripping end of the card transfer component grips a single card from the card storage component and transfers the card to the corresponding bonding area of the substrate at the card-applying station. The card transfer component corresponding to each card-applying station can move precisely between the card storage component and the corresponding card-applying station, ensuring the accuracy of the card's placement on the substrate. This card placement device does not require significant modifications to the original gripping and storage structures of the bag-making equipment. Multiple card placement components are independently set up, each corresponding to a card-applying station, reducing the difficulty and cost of modifying the bag-making equipment. Simultaneously, it improves the versatility of the bag-making equipment, flexibly adapting to the bonding needs of single, double, or multiple cards, and accommodating diverse bag-making processes.

[0052] As mentioned in the background section, existing bag-making equipment requires significant modifications to the card gripping and storage structures when installing multiple cards. Furthermore, the space required for the simultaneous transfer of multiple cards is substantial, which not only hinders the design of nearby components but also makes the cards highly susceptible to interference from nearby components, leading to detachment or displacement and severely reducing the yield of finished packaging bags.
[0053] To address this issue, the present invention provides a card placement device for a bag-making equipment. By setting up multiple independent card placement components, it solves the problem of large space occupation when multiple cards are transferred simultaneously, which is detrimental to the overall layout of the bag-making equipment and the design of surrounding components.
[0054] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0055] like Figure 1 and Figure 2As shown, in this embodiment, the card placement device includes multiple card placement components 10, which correspond to the corresponding card-attaching stations of the bag-making equipment and are fixed on the frame 20 of the bag-making equipment. The card-attaching station refers to the position on the substrate that needs to be affixed with a card when the transport component 30 transports the substrate to a predetermined position. The substrate may have one corresponding card-attaching station or two corresponding card-attaching stations at the predetermined position. This embodiment does not limit this to a single station.
[0056] It should be noted that the number of card placement components 10 can be two, three, four or other numbers, and can be designed according to the number and position of the bonding station. This embodiment does not limit this to a single number.
[0057] The card placement component 10 is located next to the corresponding card-attaching station and includes a card storage component 100 and a card transfer component 200. Multiple cards are stacked and stored in the card storage component 100, and the gripping end of the card transfer component 200 can move between the card storage component 100 and the corresponding card-attaching station.
[0058] Furthermore, the substrate placed on the transport component 30 of the bag making equipment is transported to a card-attaching station, where the gripping end of the card transfer component 200 grips a single card from the card storage component 100 and transfers the card to the corresponding bonding area of the substrate located at the card-attaching station.
[0059] This card placement device, by setting up multiple card placement components 10 and corresponding to multiple card-applying stations, can realize the application of different functional cards on both sides or multiple positions of the packaging bag opening. The card transfer component 200 corresponding to each card-applying station can move precisely between the card storage component 100 and the corresponding card-applying station, realizing stable gripping, precise transfer and application of a single card, ensuring the accuracy of the card's application position on the substrate. Furthermore, the multiple card placement components 10 are independently set up and each corresponds to a card-applying station, reducing the difficulty and cost of modifying the bag-making equipment, while improving the versatility of the bag-making equipment. It can flexibly adapt to the application needs of single, double or multiple cards and accommodate diverse bag-making processes.
[0060] In addition, compared with the existing technology that simultaneously transfers multiple cards at one workstation, this method significantly reduces the space required for card transfer at a single card-attaching workstation, avoids the limitations imposed on the design of surrounding components by excessive transfer space, and avoids the problem of card interference with surrounding components during card transfer, which could lead to card detachment or displacement. This significantly improves the stability and reliability of card mounting.
[0061] It should be noted that the substrate is transported to the corresponding card-attaching station, where it can be used to attach cards (i.e., head cards) to the opening of the final packaged bag, or to attach cards (i.e., bottom cards) to the bottom of the packaged bag. For ease of understanding, the following explanation will take the example of the substrate having head cards attached at multiple card-attaching stations.
[0062] In this embodiment, as Figure 3 As shown, the card storage component 100 can be located on the side of the card transfer component 200 away from the corresponding card-attaching station. The gripping end of the card transfer component 200 grabs the card from the card outlet of the card storage component 100, reducing the risk of interference between the card storage component 100 and the substrate and the components transporting the substrate. Furthermore, the card outlet on the card storage component 100 is higher than the card-attaching station in the vertical direction. When the gripping end of the transfer drive component 220 takes the card from the card outlet, there is no interference from other components around it, which is conducive to accurate gripping and avoids the problems of card offset, skew, or missed gripping when taking the card.
[0063] Furthermore, the card placement component 10 also includes a mounting base 300, which is set on the frame 20 of the bag making equipment and located next to the card pasting station. The mounting base 300 enables the card placement component 10 to be stably installed, ensuring that there is no shaking or displacement during the card grabbing and transfer process, and providing a stable installation foundation for subsequent accurate card picking and pasting.
[0064] Specifically, such as Figure 3 As shown, the mounting base 300 may include a pair of spaced-apart mounting sidewalls 310. The bottom of the pair of mounting sidewalls 310 is fixedly connected to the frame 20. The card storage component 100 and the card transfer component 200 are located between the pair of mounting sidewalls 310 and mounted on the pair of mounting sidewalls 310. This open mounting structure facilitates the disassembly, assembly, and maintenance of the internal card storage component 100 and card transfer component 200. Of course, the mounting base 300 may also be configured as a semi-open housing; this embodiment does not limit this to a single design.
[0065] The specific structure and working principle of the card transfer component 200 of the card placement component 10 will be described in detail below.
[0066] like Figure 3 and Figure 4As shown, in this embodiment, the card transfer component 200 is used to transfer the cards in the card storage component 100 to the substrate of the card pasting station. The card transfer component 200 can transfer cards by swinging between the card storage component 100 and the card pasting station through a rotating component linked to the gripping end. Alternatively, it can move between the card storage component 100 and the card pasting station through a robotic arm with multi-degree-of-freedom joints linked to the gripping end. It can also move between the card storage component 100 and the card pasting station through a slide rail guide mechanism in conjunction with the linked gripping end. This embodiment does not limit this to a single method.
[0067] Specifically, the card transfer component 200 may include a rotating shaft 210 disposed below the card outlet, with a gripping end disposed on the rotating shaft 210 and aligned vertically with the card outlet. The transfer drive component 220 drives the rotating shaft 210 to rotate, and the gripping end moves between the card storage component 100 and the card attaching station. It can precisely control the movement trajectory of the gripping end, ensuring its smooth movement between the card storage component 100 and the card attaching station. It has the advantages of simple structure and stable transmission, reducing the risk of mechanical failure and maintenance costs of the card placement device.
[0068] The transfer drive component 220 is configured as a transfer drive motor 221, which is fixed on the mounting base 300. The output end is connected to one end of the rotating shaft 210, and drives the rotating shaft 210 to rotate relative to the mounting base 300. The transfer drive motor 221 has high transmission accuracy and fast response speed, and can accurately control the rotation angle and speed of the rotating shaft 210, thereby accurately controlling the motion trajectory and start and stop time of the gripping end, ensuring the accuracy and stability of card gripping and transfer.
[0069] Specifically, the output end of the transfer drive motor 221 can be connected to one end of the rotating shaft 210 via a transmission belt assembly. The transmission belt assembly includes a pair of transmission pulleys respectively sleeved on the output end of the transfer drive motor 221 and one end of the rotating shaft 210, and a transmission belt sleeved on the pair of transmission pulleys. When the output end of the transfer drive motor 221 rotates, it drives the rotating shaft 210 to rotate via the transmission belt assembly. The output end of the transfer drive motor 221 can also drive the rotating shaft 210 via a transmission gear set. The output end of the transfer drive motor 221 can also be connected to one end of the rotating shaft 210 via a coupling. This embodiment does not specifically limit this.
[0070] And, as Figure 4 As shown, the card transfer component 200 includes a support member 230 disposed in the axial center of the rotating shaft 210 and extending radially outward along the rotating shaft 210. A plurality of adsorption members 240 are disposed at intervals on one side of the support member 230, and the adsorption head of each adsorption member 240 is facing the card outlet as a gripping end.
[0071] In this embodiment, multiple adsorption components 240 located on the support member 230 firmly grasp a single card through adsorption force, preventing the card from falling off or tilting during grasping and transfer. The spacing of the multiple adsorption components 240 also accommodates cards of different sizes, improving the applicability of the card placement device. Of course, the grasping end can not only grasp cards through adsorption but can also be equipped with a gripper structure that can clamp the card from both sides; this embodiment is not limited to this specific method.
[0072] More specifically, the support member 230 can be configured as a plate structure, each adsorption member 240 is a suction cup 241, and the card placement assembly 10 also includes a pressing drive component 250 that is pulsatorically connected to the suction cup 241. The pressing drive component 250 can be configured as a commonly used drive source such as a linear motor, hydraulic cylinder, or pneumatic cylinder commonly used in the art. This embodiment does not limit it to a single type.
[0073] The pressing drive component 250 is located on the other side of the support member 230, is connected to the gripping end in a transmission manner, and can drive the gripping end to move relative to the support member 230.
[0074] In this embodiment, the pressing drive component 250 can drive the gripping end (suction cup 241) to move relative to the support component 230 and the rotating shaft 210, flexibly adjusting the posture and position of the gripping end to adapt to the card exit height of the card storage component 100 and the substrate bonding area position of the card pasting station, further improving the smoothness and accuracy of card picking and placing; and after the card is transferred to the preset bonding area of the substrate, the pressing drive component 250 can drive the support component 230 and the suction cup 241 to press down simultaneously, pressing the card tightly onto the pre-coated bonding area, so that the adhesive layer between the card and the substrate is fully bonded, significantly strengthening the connection strength of the card on the substrate, avoiding the problem of the card not being firmly bonded and falling off later, further improving the reinforcement effect of the packaging bag opening and the stability of the product structure.
[0075] Of course, the card transfer component 200 can also be configured with other structures. When the card transfer component 200 adopts the structure of a robotic arm, the robotic arm may include a first robotic arm and a second robotic arm. A multi-degree-of-freedom joint is provided between the first robotic arm and the second robotic arm. The first robotic arm is mounted on the platform 20, and the gripping end is located at the free end of the second robotic arm. The first robotic arm can swing relative to the platform 20, and the second robotic arm can swing relative to the first robotic arm, thereby linking the gripping end to move. When the card transfer component 200 adopts a slide rail guide mechanism, the gripping end of the card transfer component 200 is slidably mounted on the slide rail, and the two ends of the slide rail are respectively located at the card-attaching station and the corresponding position of the card storage component 100. The gripping end is driven to move on the slide rail by the transfer drive component 220. The slide rail can extend along an arc or use multiple sets of linear slide rails in combination. This embodiment does not specifically limit this.
[0076] Therefore, the card placement component 10 can move the card through any of the card transfer components 200 described above. The card transfer components 200 of each card placement component 10 can adopt the same or different structures, and those skilled in the art can design them according to actual conditions and specific needs.
[0077] The specific structure and working principle of the card storage component 100 of the card placement component 10 will be described in detail below.
[0078] like Figure 3 and Figure 5 As shown, in this embodiment, multiple cards are stacked and stored in the receiving slot of the card storage component 100, and the card storage component 100 has an open card outlet at one end near the card pasting station in the card stacking direction.
[0079] The gripping end of the card transfer component 200 grips the outer wall of the card near the card exit and pulls it out from the card exit.
[0080] The receiving slots act as a guide, preventing stacked cards from becoming scattered or tilted during storage and ensuring all cards remain neatly stacked for precise card grabbing. Furthermore, the grabbing end grasps the outer wall of the card closest to the exit and extracts it from the card exit, enabling smooth single-card grabbing and preventing multiple cards from sticking together during the grabbing process. This method of grasping the outer wall also prevents damage to the card itself, ensuring card integrity.
[0081] Specifically, the receiving slot extends downwards from the top, inclined relative to the vertical direction, toward the card-applying station. The end of the receiving slot near the card-applying station is open to form a card outlet. The inclined receiving slot utilizes the weight of the cards themselves to keep stacked cards close together toward the card outlet, ensuring that cards near the outlet are always in the preset gripping position. This prevents cards from getting stuck or misaligned within the receiving slot, further improving the smoothness and success rate of card retrieval.
[0082] Furthermore, the tilt angle of the receiving slot relative to the vertical direction is within the range of 30° to 60°. For example, the tilt angle of the receiving slot relative to the vertical direction can be 30°, 35°, 45°, 60°, or other tilt angles within the above range. This receiving slot ensures the stability of card storage while satisfying the smoothness of card feeding. If the angle is too large (e.g., greater than 60°), it is easy for cards to slip too quickly and become scattered when stacked, while if the angle is too small (e.g., less than 30°), gravity cannot be fully utilized to bring the cards together.
[0083] More specifically, such as Figure 5As shown, the card storage component 100 may include three spaced-apart supporting bottom walls 110 and a pair of spaced-apart limiting side walls 120. The lower sidewalls of the pair of limiting side walls 120 are fixedly connected to the upper sidewalls of the corresponding supporting bottom walls 110, thereby forming a receiving groove with the three supporting bottom walls 110 and the pair of limiting side walls 120. This structure not only effectively restrains stacked cards but is also lightweight. Of course, the card storage component 100 may also be configured as a drawer-shaped housing; this embodiment does not limit it to this.
[0084] Furthermore, such as Figure 5 As shown, the card storage component 100 also includes a blocking member 130, which is disposed at the card outlet and located at both ends of the receiving groove in the length direction of the card.
[0085] In this compartment, the outer wall of the card closest to the card outlet abuts against the blocking member 130. The blocking member 130 can prevent the stacked cards from sliding off the outlet on their own and can achieve precise positioning to prevent the cards from sliding off too quickly and stacking up haphazardly, thus ensuring the stability of card storage.
[0086] In this embodiment, the blocking member 130 includes a pair of baffles 131 spaced apart along the length of the card. The pair of baffles 131 are respectively fixedly installed on the ends of the two side walls of the receiving groove and extend toward each other. That is, the pair of baffles 131 are respectively disposed on the lower end surface of the corresponding limiting side wall 120. The outer walls of the two ends of the card closest to the card outlet in the receiving groove abut against the pair of baffles 131. At this time, the card outlet is actually the gap between the lower side of the pair of baffles 131, the pair of limiting side walls 120 and the supporting bottom wall 110. After the gripping end grips the card, it pulls the card out from this gap.
[0087] This blocking member 130 has a compact structure and does not occupy the outer wall surface of the card being gripped, that is, it does not interfere with the gripping action of the gripping end on the outer wall of the card. Furthermore, a pair of baffles 131 extend toward each other and are fixed to the end of the side wall of the receiving groove. At the same time, the pair of baffles 131 only abut against the outer walls at both ends of the card, without damaging the card surface and ensuring the integrity of the card.
[0088] Of course, the blocking member 130 can be configured as a rod-shaped structure or a block-shaped structure, and this embodiment does not limit it to only one.
[0089] Furthermore, in this embodiment, the card storage component 100 also includes a plurality of auxiliary limiting rods 140, such as two, four, five or other numbers of auxiliary limiting rods 140. The plurality of auxiliary limiting rods 140 are spaced apart along the length direction of the card on the open side of the receiving slot, and the lower end of each auxiliary limiting rod 140 extends toward the card outlet and abuts against the edge of the card closest to the card outlet in the receiving slot.
[0090] Multiple spaced auxiliary limiting rods 140 can precisely limit the card closest to the exit from the open side of the receiving slot. Together with the end limiting of the baffles 131 on both sides, they prevent the card from shifting or warping in the width direction, ensuring that the card always maintains a flat and regular posture, further improving the accuracy of card retrieval and avoiding problems such as unstable gripping or missed grabbing due to card warping or shifting. In addition, the lower end of the auxiliary limiting rods 140 extends towards the card exit and abuts against the edge of the card, which neither obstructs the gripping space of the card exit nor interferes with the gripping action of the gripping end on the outer wall of the card. At the same time, it can also prevent the card from sliding off the open side of the receiving slot under the action of gravity, further improving the success rate of card retrieval.
[0091] Of course, the receiving slot of the card storage component 100 can also extend horizontally, and a clamping member, such as a coil spring, is provided on the side of the receiving slot away from the card transfer component 200. The clamping force of the coil spring makes the stacked cards always adhere and move closer to the card exit direction.
[0092] This embodiment also discloses a bag-making device, including a frame 20, a transport component 30, and a card placement device for any of the aforementioned bag-making devices. It should be noted that the transport component 30 can be a transport belt commonly used in the art or a structure that utilizes a movable adsorption structure to adsorb and transport the substrate; this embodiment does not specifically limit its use.
[0093] Among them, such as Figure 1 As shown, the bag making equipment may include two pairs of card-applying stations arranged along the bag making path. The two pairs of card-applying stations are arranged sequentially along the bag making path. Taking a side-sealed packaging bag as an example, the two front parts of the base material that constitute a pair of packaging bags are spread out in a direction perpendicular to the transport direction. The parts that constitute the bag opening are located on both sides of the transport component 30. Each pair of card-applying stations is arranged on both sides of the transport component 30. A corresponding card placement component 10 is provided next to each card-applying station.
[0094] like Figure 2 As shown, the bag making equipment may also include at least one pair of card-applying stations set on the bag making path. Each pair of card-applying stations is arranged sequentially along the bag making path. Taking a bottom-sealed packaging bag as an example, the two front parts that constitute a pair of packaging bags on the substrate are spread out along the transport direction, and the parts that constitute the bag opening are located on the same side of the transport component 30. A corresponding card placement component 10 is set next to each card-applying station.
[0095] The transport component 30 of this bag-making equipment can continuously convey the substrate along the bag-making path. In conjunction with the card-applying stations and corresponding card placement components 10 arranged sequentially along the bag-making path, the corresponding card-applying operation can be achieved by using the card placement components 10 corresponding to each pair of card-applying stations. Furthermore, this bag-making equipment can flexibly adjust the number and arrangement of card-applying stations according to the card-applying requirements of the packaging bags (single or double-sided, single or multiple cards), adapting to the production of packaging bags of different specifications and with different reinforcement requirements, greatly improving the versatility and adaptability of the bag-making equipment.
