Description

Technical Field

[0001] Embodiments of the present invention belong to the broad technical field of automation, and are particularly directed to in-line processing of elastic compressible articles. More specifically, the present invention relates to a system and method for automatically processing elastic compressible articles, such as pulling / peeling, stacking, counting and packaging of elastic compressible articles. Background Art

[0002] Due to the growing demand, the number of gloves produced has increased significantly, especially in industries such as healthcare, manufacturing and food processing. This large volume of production requires efficient and automated processes to meet demand and remain cost-effective. When dealing with large quantities of items, traditional manual handling and packaging methods become impractical and time-consuming.

[0003] In the past, automation in glove production has focused primarily on stacking and counting machines, which have helped streamline some aspects of the process. However, the lack of an automated packaging system means that after counting, the gloves must be manually transferred to a packaging station where they must be manually packaged by humans. Manual packaging results in increased labor costs, reduced production rates, and the potential for error or contamination.

[0004] In recent years, attempts have been made to address these shortcomings with automated glove packaging systems, but they remain separate entities from the stacking and counting machines. These separate systems result in a disjointed workflow where gloves must be transported between different machines, causing delays and inefficiencies. The lack of integration increases the risk of contamination during transfers.

[0005] Furthermore, separate systems take up more workspace, making it challenging to optimize the layout of a production facility. Furthermore, the transfer of gloves between different machines causes delays in production timelines, affecting overall efficiency. Furthermore, the transfer of gloves from one system to another increases the possibility of contamination, thereby affecting the quality of the final product.

[0006] Recognizing these challenges, the present invention introduces an innovative continuous processing system. This approach seamlessly integrates the key stages of glove production covering picking / stripping, stacking, counting and packaging, eliminating the need for manual transfers and providing a consolidated and space-saving solution. The continuous system not only improves production efficiency but also addresses contamination risks, thereby improving the overall operational efficiency of glove manufacturing. Summary of the invention

[0007] The present invention introduces a system and method for automated handling of elastically compressible articles, specifically gloves. The comprehensive solution integrates various mechanisms including stripping devices, conveying devices, lifting devices, picking devices, glove carriers, forming devices, and inserting devices into an integrated system. The method includes the precise steps of stripping, conveying, counting, stacking, pressing, and packaging gloves seamlessly. The notable feature is the elimination of separate entities and waiting times, resulting in a continuous, efficient, and safe process without manual transfers.

[0008] The main purpose of the present invention is to improve the operational efficiency of the production of elastically compressible articles, particularly gloves. The present invention greatly simplifies the entire process by integrating the various stages into one integrated system, thereby ensuring a seamless flow from initial stripping to final packaging.

[0009] Another object of the present invention is to optimize workspace utilization. Eliminating separate systems and integrating multiple functions creates a more compact and efficient production layout. This not only saves valuable space, but also helps to form a more organized and streamlined workspace.

[0010] Furthermore, the present invention aims to reduce the labor costs associated with manual transfer and packaging. By achieving automation, the need for extensive manual labor is minimized, thereby improving cost-effectiveness and resource optimization for glove manufacturers.

[0011] Furthermore, the present invention aims to minimize the risk of contamination during the production process. The integration of a continuous processing system eliminates the need for manual transfers between different machines, thereby reducing the chance of contamination and ensuring high quality of glove production.

[0012] Essentially, the present invention aims to revolutionize the automated handling of elastically compressible articles, providing a comprehensive solution that not only addresses the challenges associated with traditional methods, but also brings a range of advantages in terms of increased efficiency and cost-effectiveness as well as improved product quality.

[0013] Preferably, in one embodiment, the present invention introduces a unique automatic peeling mechanism using half rollers. These half rollers engage and rotate inwards to effectively peel elastic compressible articles, such as gloves, from the production line. This mechanism ensures a precise and controlled peeling process.

[0014] Preferably, in one embodiment, the present invention comprises a transfer station equipped with a double conveyor: a first conveyor (usually a conveyor belt) and a second conveyor. The first conveyor receives the products from the stripping station, while the second conveyor facilitates the smooth transfer of the products to the counting and stacking station, using an advanced mechanism of an image pickup device for efficient transfer.

[0015] Preferably, in one embodiment, the present invention comprises a counting and stacking unit having temporary glove storage bins aligned with the second conveyor. Each bin has a pressing device located above it, thereby ensuring that the products are effectively pressed to release air after being conveyed into the bin. This allows the products to be neatly stacked and compact in the bin.

[0016] Preferably, in one embodiment, the present invention introduces an intermediate liftable tray as a distinguishing feature. In an embodiment, the tray engages with the temporary glove storage bin, thereby facilitating efficient transfer of stacked gloves. The third transfer unit comprising the movable tray ensures continuous and synchronized rotation, thereby optimizing the flow of gloves from the counting and stacking unit to the packaging station.

[0017] Preferably, in one embodiment, the present invention comprises a packaging unit with a loading station having a movable glove carrier on a track, thereby ensuring a smooth transfer from the third transfer unit without delay. The present invention also comprises a deck unit with a packaging box loading and forming station, thereby providing a systematic approach to glove packaging. The inserting station with a seven-in-one inserting combination accurately completes the packaging process.

[0018] The central embodiment of the present invention is an integrated continuous processing system that seamlessly links all key stages of glove production together. This embodiment eliminates the need for manual transfers between different machines, providing an integrated and space-saving solution. The continuous system improves overall operational efficiency while mitigating contamination risks.

[0019] In summary, the various embodiments of the present invention collectively contribute to a sophisticated and comprehensive system for automatically processing elastically compressible articles, particularly gloves. Each embodiment addresses specific challenges in the production process, ultimately forming a system that is both innovative and efficient and suitable for the glove manufacturing industry.

[0063] In the detailed description below, many specific details are set forth in order to fully understand the present invention. However, it will be appreciated by those skilled in the art that the present invention can be implemented without these specific details. In other cases, well-known methods, procedures and / or components are not described in detail to avoid obscuring the present invention.

[0064] The invention will be more clearly understood from the following description of embodiments of the invention given by way of example only with reference to the accompanying drawings, which are not drawn to scale.

[0065] As used in this disclosure and the appended claims, the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates or indicates otherwise.

[0066] Throughout the disclosure and claims of this specification, the word "comprise" and its variations, such as "include" and "have", means "including but not limited to", and is not intended to exclude, for example, other components, elements or steps. "Exemplary" means "as an example" and is not intended to indicate a preferred or ideal embodiment, and "such as" is not used in a limiting sense, but for illustrative purposes.

[0067] Embodiments of the present invention are primarily focused on a system 1 and method 100 for automatically handling at least one elastically compressible article 3, including but not limited to pulling / peeling, stacking, counting and packaging processes. The term "elastically compressible article" as used in this document encompasses a variety of glove types, including but not limited to vinyl gloves, nitrile gloves, latex gloves, medical gloves, safety gloves, etc.

[0068] In the preferred embodiment depicted, as in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in , the automatic system 1 is used to pull / peel, stack, count and package at least one elastically compressible product, and the system includes several interconnected units, stations or devices that operate as an integrated system 1. An integrated system refers to the fusion and integration of multiple units, stations or systems to achieve dynamic interaction in order to achieve continuous productivity, improve efficiency or achieve centralized management. The automatic system 1 includes at least one product peeling unit 7, at least one product conveying unit 9, at least one product counting and stacking unit 11, at least one product transfer unit 13, at least one product packaging unit 15 and at least one system control unit (not shown), which is responsible for supervising, regulating, signaling, indicating or operating the functions of the entire system. These units 7, 9, 11, 13, 15 are preferably interconnected within the system structure 5. In addition, they can be interconnected to each other via different system structures 5 to form an integrated system. In one embodiment, the automatic system 1 only includes at least one product conveying unit 9, at least one product counting and stacking unit 11, at least one product transfer unit 13, at least one product packaging unit 15 and at least one system control unit (not shown). In this configuration, the peeling unit 7 can be provided as a separate independent system.

[0069] According to embodiments of the present invention, various transfer methods or any suitable transfer methods may be used to transfer the elastically compressible articles between units 7, 9, 11, 13, 15. These transfer methods include, but are not limited to, pick-and-place systems, robotic arms, conveyors, suction and discharge mechanisms, pull and discharge systems, etc. Additional alternatives for transfer methods may include pneumatic grippers, magnetic conveyors, vacuum suction arms, shuttle systems, and sliding transfer trays.

[0070] Although the present invention is intended for use in an integrated system, it is contemplated that the present invention may be divided into multiple systems depending on the needs and applications of the user.

[0071] The product stripping unit 7 of the system 1 comprises: at least one stripping / pulling device 7a, connected to the system structure 5; and at least one power transmission unit 7b, such as a gear, a motor, a belt or a chain, connected to the stripping / pulling device 7a, for motorizing the stripping / pulling device 7a. Preferably, the stripping / pulling device 7a is a pair of half rollers 7c, which are intended to be spaced apart to form a glove channel 7d and engage with the dipping line in the glove production process. When the gloves 3 are semi-demolded from the hand mold device during the final stage of the glove production line, they pass through the channel 7d between the half rollers 7c of the product stripping unit 7. When a preset number of gloves 3 is reached or detected, the half rollers 7c engage with each other, wherein the surfaces of the half rollers 7c are attached to each other, clamping the gloves 3, and rotating inwardly by the power transmission unit 7b, thereby effectively pulling the gloves 3 out of the mold device. Preferably, a detection sensor (not shown) is used to detect the number of gloves 3 passing through the half rollers 7c, so as to be used for the system control unit to instruct the half rollers 7c to operate. After the glove 3 has been stripped, the half-rollers 7c disengage from each other and reform the glove channel 7d, so that the glove 3 is released, and the half-rollers rest for the next stripping cycle.

[0072] The product conveying unit 9 of the system 1 is connected below the product stripping unit 7, and includes at least one first conveying device 9a, which is usually one of a group of conveying belts 9b. This arrangement is strategically significant so that the gloves 3 stripped from the dipping line can be received simultaneously. The conveying belts 9b operate in parallel, thereby enhancing the system's ability to effectively process multiple gloves 3 at the same time. The gloves 3 are laid on these conveying belts 9b after being stripped from the dipping line by the stripping device 7a. Subsequently, the conveying belts 9b transport the gloves 3 to subsequent stations, specifically to the counting and stacking unit 11 of the system 1, based on the signal of the system control unit. Alternatively, the first conveying device 9a can be operated continuously without waiting for the signal of the system control unit.

[0073] In addition, the product transfer unit 9 of the system 1 further comprises at least one second transfer device 9c, which is connected after the first transfer device 9a and is used to transfer the gloves 3 from the conveyor belt 9b of the first transfer device 9a to the counting and stacking unit 11 of the system 1. Although it is conceivable that a picking, pulling, suction or similar device may also be used, the second transfer device 9c in the product transfer unit 9 is preferably in the form of a clamping device. Figure 6-A , Figure 6-B , Figure 6-C and Figure 6-D The operating mechanism of the second conveying device 9c is further shown.

[0074] In this embodiment, the conveying device is a pair of clamps 9d mounted on the first mounting device 9e. When the glove 3 is transferred from the front of the first conveying device 9a to the end, the clamp 9d is opened under the control of the system control unit to fix the wrist portion of the glove 3. Subsequently, the mounting device 9e moves backward to a position above the counting and stacking unit 11, while transporting the clamped glove 3 and the clamp 9d mounted thereon. After that, the clamp 9d is opened to release the glove 3 onto the counting and stacking unit 11. Then, the clamp 9d and the first mounting device 9e return to the initial position for subsequent cycles.

[0075] Next comes the counting and stacking unit 11 of the system 1, which is connected to the product conveying unit 9 and includes a temporary glove storage bin 11a or a group of such bins 11a. These bins 11a are aligned with the second conveyor 9c and the first conveyor 9a to facilitate the organized flow of gloves 3. When the gloves 3 are laid on the conveyor belt 9b after the stripping process, they move in an orderly manner, lined up in a row, and go to their designated temporary glove storage bins 11a.

[0076] A key feature within the counting and stacking unit 11 is that a pressing device 11b is strategically positioned above each bin, which is configured to press the gloves 3 as they are transferred into the bin 11a to release excess air in the gloves 3, such as Figure 6-E As further shown in the figure, the stacked gloves 3 in the bin 11a do not occupy unnecessary space and are kept in a compact arrangement. In order to maintain an orderly count of the gloves in the bin, a counter (not shown) is provided to cooperate with the pressing device 11b to keep track of and record the number or quantity of gloves 3 in the bin 11a. The counter can count when the pressing device 11b is pressed or when the gloves 3 are transferred to the bin 11a. When the stripping and transfer process is repeated, the gloves 3 are stacked in the bin 11a in an orderly manner, wherein each glove 3 is gently compressed by the pressing device 11b. This dual function ensures not only an organized stacking process, but also ensures accurate recording of the number of gloves 3 in the bin 11a. The independent cooperation of the counter and the pressing device 11b makes the counting mechanism flexible, which further helps to improve the accuracy and efficiency of the entire system 1.

[0077] The top of the temporary glove storage bin 11a is open and the bottom is closed by a bin door 11c that can be opened and closed automatically. When the gloves 3 reach a predetermined number, the bin door 11c releases them from the bin under the control of the system control unit. Each bin door 11c can function independently or together based on the system control unit. The number of temporary glove storage bins 11a and pressing devices 11b should be set to be the same as the number of first conveying devices 9a and second conveying devices 9c. The number of temporary glove storage bins 11a, pressing devices 11b, first conveying devices 9a and second conveying devices 9c should be increased accordingly so that the entire system 1 can adapt to a faster production speed.

[0078] The article transfer unit 13 is a distinguishing feature of the system 1 and is used to efficiently transfer the gloves 3 from the counting and stacking unit 11 to the packaging unit 15 within the same system 1, thereby eliminating the need for a separate system. Figure 7-A , the product transfer unit 13 includes at least one anti-drop mechanism or anti-gravity device for transferring the product 3. The anti-drop mechanism or anti-gravity device is configured to facilitate the transfer of the product 3 between the counting and stacking unit 11 and the packaging unit 15, wherein the anti-drop mechanism or anti-gravity device greatly reduces or eliminates any drop effect during the transfer process. The anti-drop mechanism or anti-gravity device can cover various mechanisms or methods, including any technology that effectively reduces or minimizes the drop effect during the transfer process, regardless of the specific implementation method.

[0079] In a specific embodiment, the anti-drop mechanism or anti-gravity device comprises an intermediate liftable tray 13a, possibly a group of such trays 13a, which are arranged below or connected to the counting and stacking unit 11, specifically arranged below or connected to the temporary glove storage bin 11a. The tray 13a is controlled by at least one lifting device 13b under the control of the system control unit, which is configured to rise from the initial position door leaf of the tray (as defined by the letter "A") to a position below the temporary glove storage bin 11a (as defined by the letter "B") when the bin 11a is filled with stacked gloves 3 or reaches its capacity. Figure 7-A , Figure 7-B , Figure 7-C and Figure 7-DThe working mechanism of this intermediate liftable tray 13a is shown. Preferably, the tray 13a rises upward to establish a connection with the bin 11a and engage with the bin 11a. When the bin door 11c is opened, the gloves 3 are neatly placed or kept in the tray 13a, thereby avoiding any erroneous or missed drops. After the gloves 3 are accommodated in the tray 13a, the tray descends back to its initial position for subsequent transfer. This careful design eliminates the potential problems faced by traditional systems, in which the gloves 3 falling from full height often cause missed drops due to various reasons. Such missed drops or stacking of gloves 3 may interfere with the system, causing jamming or collapse. Therefore, the intermediate liftable tray 13a is intended to prevent the gloves 3 from falling directly into the tray 13a from full height, which is a common practice in traditional systems. This precaution is crucial in avoiding missed drops and potential interference with system functions.

[0080] Figure 8-A , Figure 8-B , Figure 9-A and Figure 9-B The interaction between the bin 11a and the liftable tray 13a is further illustrated in a perspective view and a top view, respectively, specifically highlighting at least one anti-obstruction engagement device, which ensures unimpeded opening and closing of the bin 11a when the liftable tray 13a is in an engaged state. The anti-obstruction engagement device preferably features a bin door 11c, which includes a single door leaf 11d or a pair of door leaves 11d. Each door leaf 11d is composed of a series of first spaced-apart members 11e. The anti-obstruction engagement device is also characterized by a liftable tray 13a, which includes a single tray leaf 13c or a pair of tray leaves 13c, wherein each tray leaf 13c is composed of a series of second spaced-apart members 13d. During the engagement process, each second spaced-apart member 13d is raised in the direction of the space 11f between each first spaced-apart member 11e. This arrangement ensures that the opening of the first spaced-apart members 11e is not obstructed. When the first spaced apart members 11e are opened, they swing within the spaces 13e between the second spaced apart members 13d, thereby facilitating smooth and unhindered movement.

[0081] The intermediate liftable tray leaf 13c can also be opened and closed to release the gloves to a subsequent station or unit called the third transfer unit 14, which is part of the article transfer unit 13. Figure 10-A , Figure 10-B , Figure 10-C and Figure 10-D , which shows the glove transfer process from the intermediate liftable tray 13a to the third transfer unit 14.

[0082] The third transfer unit 14 is connected below the intermediate tray 13a and includes at least one movable tray 14a. In one embodiment, the movable tray 14a is slidably mounted on a tray turntable 14b that can rotate to adjust the positioning of the gloves 3. The tray turntable 14b slides and / or rotates in a track unit 14c below the intermediate liftable tray 13a, thereby ensuring a carefully designed drop height to prevent gloves from being missed and dropped. The track unit 14c is preferably capable of switching between a first position and a second position by a moving mechanism.

[0083] Preferably, the movable tray 14a includes a plurality of raised sides 14d with an open top in a box-like configuration. When the intermediate liftable tray 13a is configured to release the stacked gloves 3 from the tray leaf 13c, the tray leaf 13c swings downward and engages with the inner side of the movable tray 14a, so that the stacked gloves 3 are released onto the movable tray 14a in a closed manner, thereby preventing the gloves 3 from being missed and falling. After the movable tray 14a of the third transfer unit 14 is filled with the stacked gloves 3 from the intermediate tray 13a, the intermediate tray leaf 13c is closed, and the movable tray 14a slides to a subsequent station, which will be explained in detail in the following paragraphs.

[0084] refer to Figure 11-A , Figure 11-B , Figure 11-C and Figure 11-D , the pallet turntable 14b slides together with the attached full movable pallet 14a toward the packaging loading station 15a located at one end in the product packaging unit 15. The packaging loading station 15a includes a pallet receiving unit 15b capable of receiving the movable pallet 14a from the track unit 14c. In addition, the packaging loading station 15a includes a pallet discharging unit 15c responsible for discharging an empty movable pallet 14a. When arriving at the packaging loading station 15a, the full movable pallet 14a can be discharged from the pallet turntable 14b or disassembled into the pallet receiving unit 15b.

[0085] The track unit 14c carrying the tray carousel 14b without the movable tray 14a can switch its position from the first position (which discharges the movable tray to the tray receiving unit) to the second position (which receives the empty movable tray 14a from the tray discharge unit 15c) upon receiving a signal from the system control unit. This enables the empty movable tray 14a to be moved into the tray carousel 14b, thereby preparing for the next set of gloves 3 or a subsequent cycle.

[0086] The full movable tray 14a, now located at the tray receiving unit 15b, awaits the next stage, in which it will become the focus of picking by at least one picking device 151 in the product packaging unit 15, in preparation for the subsequent packaging process. After picking up the gloves 3 from the full movable tray 14a, the tray 14a is transformed into an empty state and smoothly moved back to the designated station, namely the tray discharge unit 15c, ready to receive the next group of gloves 3. This strategic rotation of the movable tray 14a ensures a continuous flow of gloves 3, thereby optimizing the efficiency of the entire automated process. The tray receiving unit 15b and the tray discharging unit 15c can be operated in various ways, such as using a conveyor track system, where the movable tray 14a continuously travels from one end (tray receiving unit 15b) to the other end (tray discharging unit 15c), and the gloves 3 are picked up during the travel process; or utilizing a first waiting area (tray receiving unit 15b) and a second waiting area (tray discharging unit 15c), where after picking up the gloves 3 from the full movable tray 14a, the picking device 15l transfers the empty movable tray 14a from the tray receiving unit 15b to the tray discharging unit 15c, so that efficient glove handling is achieved in the process. This setting eliminates delays or waiting times, helping to improve the overall efficiency of the system 1. Essentially, a group of movable trays 14a take turns to receive gloves from the intermediate tray 13a. This synchronized movement creates a continuous rotation, facilitating uninterrupted operation. This strategic rotation of the movable trays 14a not only ensures a constant flow of gloves 3, but also optimizes the efficiency and continuity of the entire automated process.

[0087] Reference now Figure 12-A , Figure 12-B , Figure 12-C , Figure 12-D , Figure 12-E , Figure 12-F The product packaging unit 15 of the system 1 includes, in addition to the packaging loading station 15a, several interconnected units for the packaging process, whereby these units are connected to the system structure 5. The product packaging unit 15 also includes at least one lifting device 15d (such as a rotating lifter capable of rotation), which is configured to transfer items, such as packaging boxes, gloves, etc., between the interconnected units of the product packaging unit 15.

[0088] The product packaging unit 15 comprises at least one packaging box loading station 15e and at least one box forming station 15f connected adjacent to the packaging box loading station 15e. The packaging box loading station 15e is designated for loading the prepared packaging box B, which is released to the box forming station 15f after loading.

[0089] At least one unfolding and / or forming mechanism is provided at the box forming station to facilitate the unfolding or assembly of the flat packaging box B into a three-dimensional shape. Alternatively, it opens the flat packaging box B along a foldable fold to form a box-like structure.

[0090] The product packaging unit 15 further comprises at least one overhead transport device 15g located above the packaging box loading station 15e and / or the box body forming station 15f and / or the lifting device 15d, and is designed or configured to perform various functions, including but not limited to transferring an empty packaging box B to the packaging box loading station 15e, or transferring an empty packaging box B from the packaging box loading station 15e to the box body forming station 15f, or transferring a formed box B from the box body forming station 15f to the lifting device.

[0091] After the flat packaging box B is unfolded into a formed box B in the box forming station 15f, the box B is transferred to the lifting device 15d by the overhead transport device 15g.

[0092] The product packaging unit 15 also includes at least one tucking station 15h, which includes at least one tucking device 15hh, wherein the tucking station is adjacently connected to the packaging box loading station 15e and the box body forming station 15f. Preferably, the tucking station is connected below the packaging box loading station 15e and the box body forming station 15f. Under the signal of the system control unit, the lifting device 15d transfers the formed box B to the tucking station 15h for the first tucking process. In the first tucking process, the first side of the formed box B is closed, and the second side is open.

[0093] The product packaging unit 15 further includes at least one product insertion module 15i adjacent to the packaging loading station 15a, the product insertion module 15i includes at least one tightening module 15j, the diameter of the tightening module is smaller than the diameter of the formed box B, wherein the tightening module has a tightening device capable of compacting or compressing the stacked gloves 3 so that the gloves 3 can be inserted into the formed box B. The tightening module 15j is connected to at least one insertion device 15k, which is responsible for starting the tightening module 15j to enter the formed box B.

[0094] The formed box B with the closed first side is transferred to the product insertion module 15i by the lifting device 15d. Then, the stacked gloves resting at the tray receiving unit 15b are picked up by the picking device 15l and placed in the tightening module 15j for the glove compacting process.

[0096] In such Fig.13 In another preferred embodiment of the present invention shown in , a method 100 for automatically handling at least one elastically compressible article (such as pulling / peeling, stacking, counting) is provided. Preferably, the method 100 is integrated with the above-mentioned system 1 and involves a series of steps to ensure a streamlined and efficient process.

[0097] The method 100 for automatically processing at least one elastic compressible article 3 includes: step 101, transferring at least one elastic compressible article to a stripping unit; step 103, transferring the elastic compressible article from the stripping unit to the conveying unit; step 105, transferring the elastic compressible article from the conveying unit to a counting and stacking unit; step 107, counting and stacking the elastic compressible articles; step 109, transferring the elastic compressible article from the counting and stacking unit to the article transfer unit; step 111, transferring the elastic compressible article from the article transfer unit to the article packaging unit; the method 100 also includes a step 113 of packaging the elastic compressible article after the step 111 of transferring the elastic compressible article from the article transfer unit to the article packaging unit, wherein the method 100 is continuously performed in this order. The details of steps 101, 103, 105, 107, and 109 will be discussed in detail in the following paragraphs.

[0098] The method 100 begins at step 101: transferring at least one elastically compressible article to a stripping unit. Initially, the elastically compressible article undergoes a precise stripping or pulling process facilitated by half rollers, as explained in the previous system description. The engagement, inward rotation and subsequent disengagement of these half rollers effectively pulls the article out of the production line. Thereafter, the half rollers are disengaged and step 103 is performed: releasing the stripped article from the stripping unit to a conveying unit, where the stripped article (specifically a glove) is laid on a conveyor belt of the conveying unit.

[0099] Continuing in this order, the method 100 proceeds to step 105: transferring the elastically compressible article from the conveying unit to a designated counting and stacking unit. The conveying unit (covering the first conveying device and the second conveying device) involves transferring the article from the peeling unit to the first conveying device, then to the second conveying device, and finally to the counting and stacking unit through the second conveying device, which includes but is not limited to at least one device of clamping, adsorbing, pulling, grabbing or picking up, or a combination thereof.

[0100] Subsequently, the method 100 proceeds to step 107, which is a critical stage: counting and stacking the elastically compressible articles within the counting and stacking unit 107. As the articles enter the unit (specifically, into the temporary glove storage bin), they undergo a counting and stacking process. A pressing device located above each storage bin performs a pressing action as each glove enters the storage bin. This step requires a repetitive process in which the stripping and conveying steps are repeated to fill the storage bin with gloves while applying the pressing device.

[0101] When the predetermined number is reached or the capacity is reached, the method 100 transitions to step 109: transferring the elastically compressible articles from the counting and stacking unit to the article transfer unit, such as Fig.14 This involves step 109a: raising at least one intermediate liftable tray of the product transfer unit by a lifting device to engage with the door of at least one temporary glove storage bin of the counting and stacking unit; and then performing step 109b: releasing the gloves onto the liftable tray by opening the door of the temporary glove storage bin. The door of the temporary glove storage bin is opened so that the stacked gloves can be placed and laid on the liftable tray, wherein, by at least one anti-obstruction device, the engagement of the liftable tray does not hinder the opening of the door, thereby enabling the gloves to be placed on the liftable tray.

[0102] Subsequently, the door is closed and step 109c is performed: returning the liftable tray to its initial position for subsequent transfer. The method 100 also involves step 109d: arranging a third movable tray to receive the stacked gloves from the intermediate tray. The door of the intermediate tray is opened, releasing the stacked gloves into a third movable tray slidably mounted on a tray turntable, which then slides within the track unit to transfer the stacked gloves to the product packaging unit. The third movable tray can be rotated to optimize the position or orientation of the gloves, thereby ensuring a smooth packaging process. Preferably, the third movable tray is slidably mounted on a tray turntable, which can rotate and slide within the track unit, whereby the track unit can be switched between a first position and a second position by at least one moving mechanism. This integrated method 100 emphasizes the integration and efficiency achieved by the system for automatic product handling of the present invention.

[0103] Then, the method 100 proceeds to step 111: transferring the elastically compressible product from the product transfer unit to the product packaging unit, such as Fig.15 As shown in . First, perform step 111a: slide the pallet turntable to one end of the track unit located at the first position, at which the packaging loading station of the product packaging unit is adjacently positioned. The packaging loading station includes: at least one pallet receiving unit, positioned adjacent to the first position of the track unit; and at least one pallet discharge unit, positioned at the second position of the track unit. Perform step 111b: move or slide the third movable pallet filled with stacked gloves from the pallet turntable to the pallet receiving unit of the packaging loading station. Then, perform step 111c: move the track unit from the first position to the second position, at which the pallet discharge unit of the packaging loading station is adjacently positioned. Subsequently, at least one empty third movable pallet is discharged from the pallet discharge unit into the pallet turntable.

[0104] After this, the method 100 proceeds to the critical step 113 of packaging the elastically compressible articles. The elastically compressible articles or stacked gloves efficiently transferred from the article transfer unit undergo a packaging process to ensure accuracy and orderliness.

[0105] Initially, the gloves in the third movable tray of the tray receiving unit are picked up in an orderly manner by at least one picking device and carefully placed into the tightening module. The module is used to compress and compact the gloves for the subsequent packaging steps. At the same time, the pre-loaded or live-loaded packaging boxes will undergo a conversion process facilitated by the forming device. This process requires unfolding or assembling the flat packaging box into a three-dimensional configuration, thereby forming a specific box shape suitable for accommodating gloves.

[0106] With the first side of the packaging box exposed, the inserting device is engaged to securely close that side. The gloves nested in the tightening module are then accurately and gently inserted into the packaging box by entering from the second side through at least one associated insertion device. The inserting device again works to ensure that the gloves are tightly inserted into the packaging box without leaving any residue or traces on the outside of the box. The second side of the packaging box is then sealed by the inserting device, effectively completing the packaging process.

[0107] This systematic method 100 ensures that the elastically compressible articles (in this case gloves) are not only accurately stripped, counted, stacked, pressed and transferred, but also efficiently and securely packaged for subsequent use. The integration of various mechanisms (including the stripping device, conveying device, lifting device, picking device, glove carrier, forming device and inserting device) exemplifies the complexity and efficacy of the automated processing system. Notably, the system operates as a unified entity, eliminating the need for separate components and eliminating the waiting time and manpower associated with the packaging process. The entire process proceeds continuously without delays, waiting periods or the need for manual transfers.

Therefore, the forms of the present invention shown and described herein are to be considered as illustrative only, and other embodiments may be selected without departing from the scope of the present invention as set forth in the appended claims.
