Description

Technical Field

[0001] The present invention relates to the technical field of glove packaging equipment, and in particular to an automatic glove feeding and sorting system. Background Art

[0002] In recent years, disposable gloves have gradually become an indispensable safety protection product in many industries due to their comprehensive performance advantages. For example, they can be applied to surgical operations and nursing inspections in the medical and health industry, food processing and catering services in the food processing industry, etc. In the production process of disposable gloves, air tightness testing is an important quality control step; this step is usually performed after the gloves are formed and before packaging. By performing this step, it can be ensured that there are no tiny holes or cracks on the gloves, thereby ensuring their protective performance. At present, the inflation test has become the most commonly used air tightness detection method due to its advantages such as high reliability, intuitive and fast, non-destructive, and strong applicability.

[0003] The basic steps of the inflation test include inflation operation and pressure measurement (or leakage observation). When performing the inflation operation, each glove generally needs to be taken out of the material basket separately and put on a special support structure in a specific posture before compressed air can be filled into the glove through special equipment. For example, the patent with publication number CN112213052A provides a method for testing the air tightness of disposable gloves, which includes step S1. Putting the wrist of the glove on the glove fixing mechanism; for another example, the patent with publication number CN217403708U provides a device for checking the air tightness of gloves, which discloses that when the air tightness of the outer rubber gloves needs to be tested, the outer rubber gloves are first put on the annular side of the round table seat.

[0004] However, although putting each glove on a special support structure in a specific posture is a routine operation of the inflation test, there is almost no feasible automated device that can achieve this operation in the existing technology of this industry, including the above two patents, so the traditional manual operation method is still used in the actual operation of the production line. According to the investigation, this is because the gloves before the air tightness test are usually piled up in a relatively random and messy manner, and the gloves themselves are soft, so it is difficult to use structures such as manipulators to straighten each glove into the same posture and put it on the support structure; and the manual operation method has the disadvantages of high labor cost and low work efficiency, which cannot be applied to large-scale production needs.

[0005] In summary, the present invention provides an automatic glove feeding and finishing system. Summary of the invention

[0006] The purpose of the present invention is to provide an automatic feeding and sorting system for gloves to solve the problem mentioned in the above background technology that when conducting air tightness testing on gloves, it is necessary to use traditional manual operation to take out each glove separately, adjust it to a specific posture and put it on a supporting structure, which has the disadvantages of high labor cost and low work efficiency and cannot be applied to large-scale production needs.

[0007] The present invention is achieved by adopting the following technical solutions: A glove automatic feeding and sorting system comprises a feeding mechanism and a sorting mechanism, wherein the feeding mechanism is used to feed each glove individually to the sorting mechanism, and the sorting mechanism is used to correct the posture of each glove to a specific posture and put it on a designated position; wherein the feeding mechanism comprises a material storage part and a material taking part, and the sorting mechanism comprises a pneumatic posture correction part and a material receiving part; the material taking part is used to take each glove out from the material storage part individually, and the taken-out glove will arrive at the pneumatic posture correction part to receive posture correction, and the posture-corrected glove will arrive at the material receiving part in a specific posture.

[0008] In the above scheme, by setting up a feeding mechanism and a sorting mechanism, the system can automatically complete the whole process of glove picking, posture correction and positioning, so as to facilitate the subsequent air tightness test of the gloves. Among them, the storage part is used to temporarily store disordered gloves, the picking part is used to take out gloves from the storage part one at a time, and the taken out gloves will then reach the pneumatic posture correction part to receive posture correction. The corrected gloves will finally reach the receiving part in a specific posture. The receiving part is used to support the gloves as required to facilitate the subsequent air tightness test.

[0009] Furthermore, the material storage part includes a displacement component and a material storage bin, the top of the material storage bin is provided with a discharge port, and the material storage bin moves on a horizontal plane along with the displacement component; the material picking part includes a lifting component and a material picking piece, the material picking piece is located above the discharge port of the material storage bin, and the material picking piece moves up and down along with the lifting component.

[0010] In the above scheme, by setting a lifting component, the material picking piece can enter the storage bin to pick up materials and leave the storage bin to deliver materials (to the pneumatic posture correction part), and can pick up materials from gloves at different heights in the storage bin; by setting a displacement component, the storage bin can move on the horizontal plane, so that the material picking piece can pick up materials from gloves at different horizontal positions; therefore, the material picking piece only needs to perform a linear lifting movement to complete the material picking operation for all gloves in the storage bin. It should be particularly noted that in actual applications, when arranging the specific positional relationship between the storage part and the material picking part, and setting the specific positions of each structure in the storage part and the material picking part, it is necessary to ensure that during the horizontal movement of the storage bin, there will be no misalignment between the material picking piece and the storage bin, that is, the material picking piece can always successfully descend to the inside of the storage bin to pick up materials.

[0011] Furthermore, the displacement assembly includes a translation structure and a rotation structure, the translation structure includes a translation force member and a translation plate driven by the translation force member, the rotation structure includes a rotation power member and a slewing bearing driven by the rotation power member; the slewing bearing is rotatably arranged on the translation plate, and the storage bin is arranged on the slewing bearing.

[0012] In the above scheme, under the action of the rotating power member, the slewing bearing can drive the storage bin to perform rotational motion; and under the action of the translational power member, the translation plate can indirectly drive the storage bin to perform translational motion by driving the slewing bearing; thus, based on the combined movement of the translation structure and the rotation structure, gloves at different positions in the storage bin all pass through the material picking member, thereby realizing the material picking operation for all gloves in the storage bin.

[0013] Furthermore, the material picking piece is in the shape of a rod with a hollow interior and a vacuum extracted, the lifting assembly includes a lifting power piece and a wheel group driven by the lifting power piece, the wheel group includes a driving wheel and a pressure wheel as a driven wheel, the driving wheel and the pressure wheel are respectively arranged on both sides of the material picking piece and are in contact with the surface of the material picking piece.

[0014] In the above scheme, driven by the lifting power part, the wheel group will rotate and generate friction between the material picking part, and the material picking rod can move up and down under the action of the friction force; wherein, when the material picking rod descends to contact the gloves in the storage bin, it will be subjected to an upward external force that stops the material picking rod from descending, and because the internal tube cavity of the material picking rod is under negative pressure, the gloves will be adsorbed onto the material picking rod.

[0015] Furthermore, the pneumatic posture correction part includes a pneumatic correction component and a material channel component, the pneumatic correction component includes an air acceleration mechanism and an air channel tube located above the air acceleration mechanism, and the air acceleration mechanism is connected to the air channel tube; the material channel component includes a feed channel and a discharge channel respectively connected to the air channel tube, wherein the discharge channel is connected to the bottom of the air channel tube through the air acceleration mechanism; when the pneumatic posture correction part corrects the posture of the glove, the glove first enters the air channel tube from the feed channel under the action of external force, and after the external force is cancelled, the upper port of the air channel tube is closed, and at the same time, the air acceleration mechanism generates an accelerated airflow downward along the circumference of its inner wall.

[0016] In the above scheme, the pneumatic correction component is used to correct the posture of the glove by forming an airflow, and the material channel component is used to provide a channel for the glove to enter or leave the pneumatic correction component; in the pneumatic correction component, the air acceleration mechanism is used to form an accelerated airflow, and the air channel tube is used to cooperate with the air acceleration mechanism, based on which the glove can be rotated in the pneumatic correction component through the airflow, thereby completing the correction of the glove posture.

[0017] Furthermore, the air channel tube comprises an outer shell, the interior of the outer shell is hollow and has openings at the top and bottom ends thereof, an opening and closing baffle is provided at the upper portion of the outer shell, and the bottom end of the outer shell is connected to the air acceleration mechanism.

[0018] In the above solution, the opening and closing baffle can automatically switch to an open or closed state, thereby being able to change the airflow condition in the air channel tube.

[0019] Furthermore, the air acceleration mechanism includes an annular main body part, the inner side of the main body part is a hollow chamber, an annular air storage chamber is provided in the main body part, an acceleration channel is connected below the air storage chamber, an air flow outlet is provided at the end of the acceleration channel, and the air flow outlet faces the discharge channel.

[0020] In the above scheme, when the air acceleration mechanism is started, compressed air will be sent into the air storage chamber, and the compressed air will be accelerated through the acceleration channel to form an accelerated airflow downward along the circumference of the inner wall of the air acceleration mechanism, and flow downward from the airflow outlet; in this process, the pressure at the center of the air acceleration mechanism becomes negative pressure, and the outside air enters the center of the air acceleration mechanism to form an upward airflow. The center of the air acceleration mechanism is the hollow chamber. Since the airflow flowing upward into the hollow chamber is relatively low-speed and high-pressure, and the accelerated airflow flowing downward along the circumference of the inner wall of the air acceleration mechanism is relatively high-speed and low-pressure, the airflow flowing upward into the hollow chamber will approach the accelerated airflow, thereby forming a curved vortex with the center pointing upward and the side wall pointing downward; when the random posture glove passes the position where the curved vortex is formed, it will rotate under the action of the curved vortex until the glove becomes a posture with the wrist facing downward and the fingers facing upward.

[0021] Furthermore, an air-permeable barrier is provided between the air acceleration mechanism and the opening and closing baffle.

[0022] In the above solution, the breathable barrier is used to limit the height of the gloves.

[0023] Furthermore, the material receiving part is located below the material discharge channel, and the material receiving part includes a material receiving assembly and a glove clamp; the material receiving assembly includes a plurality of material receiving claws distributed in a centrally divergent shape, and the plurality of material receiving claws move towards or away from each other under the drive of an opening and closing driving member, and move up and down under the drive of a lifting driving member; the glove clamp is located between the plurality of material receiving claws or below the plurality of material receiving claws.

[0024] In the above scheme, the material receiving claws are used to receive and open the gloves falling from the material discharging channel, and assist the gloves to be put on the glove clamp. Specifically: the initial positions of the plurality of material receiving claws are located above the glove clamp, and the plurality of material receiving claws first approach each other, so that after the gloves fall with the wrist facing downward and the fingers facing upward, the plurality of material receiving claws are located inside the gloves; then, the plurality of material receiving claws move away from each other to open the wrist of the glove; then, the plurality of material receiving claws move downward with the opened gloves in a state of moving away from each other, so that the gloves can be put on the glove clamp (when the plurality of material receiving claws are in a state of moving away from each other, the gaps between them are sufficient to avoid the glove clamp); then, the plurality of material receiving claws move toward each other again, and then continue to move downward to take off the gloves, thereby leaving the gloves on the glove clamp; finally, the plurality of material receiving claws return to the initial positions.

[0025] Furthermore, a signal detection device for detecting whether a glove passes through is provided in the discharge channel.

[0026] In the above scheme, a signal detection device is provided to detect whether the glove falls from the discharge channel, and the receiving claw can be linked to act.

[0027] The beneficial effects achieved by the present invention are: Provided is an automatic glove feeding and finishing system, which can automatically complete the whole process of glove picking, posture correction and positioning by setting a feeding mechanism and a finishing mechanism, and setting the finishing mechanism including a pneumatic posture correction part; wherein the posture correction is efficiently realized in a pneumatic and contactless manner.

[0036] Please refer to Figure 1 , Figure 6 and Figure 7 The receiving part 4 includes a receiving assembly and a glove clamp 401. The receiving assembly includes a square-shaped mounting frame 404, and a long strip-shaped guide frame 403 is provided at each of the four corners of the mounting frame 404. A receiving claw 402 is provided at each of the adjacent ends of the four guide frames 403. The receiving claw 402 is in the shape of a vertical cylinder (in other embodiments, the shape and number of the mounting frame 404, the guide frame 403 and the receiving claw 402 can be adjusted according to actual conditions, and the present invention does not make special restrictions on this); the mounting frame 404 is connected to the lifting drive member, and each guide frame 403 is driven by an opening and closing drive member (opening and closing The driving member may be a cylinder, a linear module, a gear rack, etc., in order to achieve the driving effect on the guide frame 403, which is not particularly limited in the present invention) and is movably mounted on the mounting frame 404.

[0037] Based on the above structure, the automatic glove feeding and finishing system provided in this embodiment can perform work according to the three basic steps of "taking materials → posture correction → positioning", specifically: Ⅰ. In the material taking step: The disordered gloves are temporarily stored in the storage bin 201. Under the action of the lifting component, the material taking part 101 can reach the storage bin 201 by descending to take a single glove from the storage bin 201, and then rise to the intersection with the pneumatic posture correction part 3; under the action of the displacement component, the storage bin 201 can move on the horizontal plane, so that the material taking part 101 can take gloves at different horizontal positions. When the lifting assembly is activated to enable the material taking part 101 to take the material, the following specific steps are included: 1) The driving wheel 102, the guide wheel 104 and the pressing wheel 103 are driven by the lifting power member, respectively as follows Figure 2 The driving wheel rotates in the direction a, the guide wheel rotates in the direction b and the pressure wheel rotates in the direction c. When the three wheels rotate, friction is generated between them and the material picking rod, thereby causing the material picking rod to descend by the friction.

[0038] 2) When the material picking rod descends to contact the gloves in the storage bin 201, it will be subjected to an upward external force that stops the material picking rod from descending. Figure 2 The air flow direction d in the inner tube cavity of the picking rod is shown, so the gloves will be adsorbed onto the picking rod.

[0039] 3) The lifting power part drives the driving wheel 102, the guide wheel 104 and the clamping wheel 103 to reverse, so that the material picking rod can rise with the glove until the glove reaches the intersection with the pneumatic posture correction part 3; when the glove enters the pneumatic posture correction part 3 under the action of external force, a new round of execution starts from step 1).

[0040] When the displacement assembly acts to move the storage bin 201, the following specific actions are included: the rotary power member drives the slewing bearing 203, as shown in FIG. Figure 3 The slewing bearing rotates in the direction e shown in the figure; at the same time, the translation plate 202 is driven by the translation force member according to the following Figure 3 The translation plate shown in the figure performs translational motion in the translational direction f; thus, based on the combined motion of the slewing bearing 203 and the translation plate 202 , the storage bin 201 undergoes a motion that enables gloves at different positions therein to pass under the material taking member 101 .

[0041] II. Posture correction steps: When the gloves reach the intersection with the pneumatic posture correction part 3 after the material taking step, the external force will send the gloves into the pneumatic correction component through the feeding channel 301, and then the pneumatic correction component will automatically correct the gloves to a specific posture by forming an airflow, and finally the gloves with a specific posture will fall to the receiving part 4 through the discharging channel 306. In this embodiment, the external force comes from the air amplifier set in the inclined tube (the extended part of the feeding channel 301) between the material taking part and the pneumatic posture correction part, and the air amplifier can spray a compressed airflow obliquely upward, and under the action of the compressed airflow, the gloves will be sucked into the pneumatic correction component; in other embodiments, those skilled in the art can use other structures or methods to achieve external force, and the present invention does not make special limitations on this.

[0042] The specific steps for the pneumatic correction component to perform its work are as follows: 1) When the material taking mechanism performs the material taking operation, the opening and closing baffle 302 is in an open state, and the air flow in the air channel tube 304 flows freely; when the glove reaches the intersection position with the pneumatic posture correction part 3, the external force acts as follows Figure 4 The feeding air direction g shown sends the glove into the feeding channel 301 and makes it pass upward through the hollow chamber 3051 of the air acceleration mechanism 305 (the air acceleration mechanism 305 is not started at this time), and then reaches the breathable barrier 303 in the air channel tube 304 and is blocked by the breathable barrier 303.

[0043] 2) After the external force is removed, the opening and closing baffle 302 becomes closed, and the air acceleration mechanism 305 is activated. The glove moves downward in the vertical direction due to gravity. When the glove moves downward to the position of the air flow outlet 3055 passing through the air acceleration mechanism 305, the glove rotates and eventually automatically finds a specific posture. The specific working principle of achieving this effect is as follows: Compressed air according to Figure 5 The compressed air is fed into the air storage chamber 3053 of the air acceleration mechanism 305 through the compressed air inlet 3052 as shown; when the air acceleration mechanism 305 is started, the compressed air is instantly accelerated through the acceleration channel 3054 to form an accelerated airflow downward along the inner wall of the air acceleration mechanism 305 (the accelerated airflow preferably reaches supersonic speed, the principle is the Laval nozzle effect), and follows the Figure 4 and Figure 5 The accelerated airflow shown in FIG. 1 flows in a direction i, flowing downward from the airflow outlet 3055 ; During this process, the pressure at the center of the air acceleration mechanism 305 becomes negative pressure, and the outside air enters the center of the air acceleration mechanism 305 to form an upward airflow. The center of the air acceleration mechanism 305 is the hollow chamber 3051. Since the airflow flowing upward into the hollow chamber 3051 is relatively low-speed and high-pressure, and the accelerated airflow flowing downward along the inner wall of the air acceleration mechanism 305 is relatively high-speed and low-pressure, the airflow flowing upward into the hollow chamber 3051 will approach the accelerated airflow, thereby forming a curved vortex with the center upward and the side wall downward. The curved vortex has the following characteristics: Figure 4 and Figure 5 The curve shown shows the vortex flow direction j.

[0044] When the glove in a random posture passes the position where the curved vortex is formed, it will rotate under the action of the curved vortex until the glove becomes a posture with the wrist facing downward and the fingers facing upward. At this time, the inner side of the glove is subjected to the upward airflow, and the air channel tube 304 on the outside of the glove is a negative pressure area, so the wrist of the glove can be stretched. The glove is suspended at the position of the airflow outlet 3055 in this posture, thereby achieving the correction of the glove posture.

[0045] 3) After the posture correction of the glove is completed, the air acceleration mechanism 305 is immediately closed, and the opening and closing baffle 302 becomes open again, and the glove falls into the discharge channel 306 under the action of its own gravity.

[0046] III. In the positioning step: The four receiving claws 402 are used to receive and open the gloves falling from the discharge channel 306, and assist the gloves to be put on the glove clamp 401, and then the four receiving claws 402 will reset to wait for receiving the next glove. The specific steps of the four receiving claws 402 are as follows: 1) The four receiving claws 402 are initially located as follows Figure 6 At the initial position k shown, the four material receiving claws 402 are in a mutually close position relationship, that is, in a position as shown in FIG. Figure 7 When a glove falls through the signal detection device 307, it will fall on the material receiving component with the wrist facing downward and the fingers facing upward. At this time, the four material receiving claws 402 are all located inside the glove. Subsequently, under the linkage of the signal detection device 307 indicating that the glove has fallen, the opening and closing drive member will drive the four guide frames 403 to move away from each other with the four material receiving claws 402, even if it becomes as shown in FIG. Figure 7 The open state t shown hereby stretches the wrist of the glove.

[0047] 2) Then, the lifting drive member drives the mounting frame 404 to carry the four material receiving claws 402 and the gloves in the stretched state to move downward, so that the four material receiving claws 402 reach the position as shown in FIG. Figure 6The mold position l is shown, so that the glove can be put on the glove clamp 401; in this process, since the four material receiving claws 402 are in the open state t, the space between the four material receiving claws 402 can avoid the glove clamp 401.

[0048] 3) Then, the opening and closing driving member drives the four material receiving claws 402 to move closer to each other, that is, to change to the closed state s again, and then the lifting driving member drives the four material receiving claws 402 to move downward, so that the four material receiving claws 402 reach the state as shown in FIG. Figure 6 The demoulding position m is shown; in this process, since the glove has been put on the glove clamp 401, when the four material receiving claws 402 become the closed state s, the glove does not fall with the material receiving claws 402 but remains on the glove clamp 401.

[0049] 4) Then, the opening and closing driving member will drive the four material receiving claws 402 to move away from each other, even if it becomes the open state t again, and then the lifting driving member will drive the four material receiving claws 402 to move upward, so that the four material receiving claws 402 are reset to the initial position k, and finally the four material receiving claws 402 wait at the initial position k for the next cycle action.

[0050] In summary, after executing the material taking step, the posture correction step and the positioning step, the disordered gloves in the storage bin 201 can be finally put on the glove fixture 401 in a specific posture, so as to facilitate the subsequent air tightness test. Based on this, the system provided in this embodiment realizes automation, which can effectively reduce labor costs and improve production quality and production efficiency.
