Description

Technical Field

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

[0002] In recent years, due to their comprehensive performance advantages, disposable gloves have gradually become indispensable safety protection supplies in many industries. For example, they can be applied to surgical operations and nursing examinations in the medical and health industry, food processing and catering services in the food processing industry, etc. In the production process of disposable gloves, airtightness detection is an important quality control step; this step is usually carried out 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, thus guaranteeing their protective performance. Currently, inflation testing has become the most commonly used airtightness detection method due to its high reliability, intuitive and fast, non-destructive, and strong applicability.

[0003] The basic steps of inflation testing include inflation operation and pressure measurement (or leakage observation). When performing the inflation operation, generally, each glove needs to be taken out from the material basket separately and put on a special support structure in a specific posture, and then compressed air can be filled into the glove through special equipment. For example, the patent with the publication number CN112213052A provides a method for detecting the airtightness of disposable gloves, which discloses the step of S1. putting the wrist part of the glove on the glove fixing mechanism; and for another example, the patent with the publication number CN217403708U provides a device for detecting the airtightness of gloves, which discloses that when it is necessary to detect the airtightness of an external rubber glove, the external rubber glove is first put on the annular side surface of the frustum base.

[0004] However, although putting each glove on a special support structure in a specific posture is a conventional operation for inflation testing, in the existing technologies of this industry including the above two patents, almost no feasible automatic device capable of realizing this operation has been proposed. Therefore, the traditional manual operation method is still adopted in the actual operation of the production line. Through investigation, it is found that this is because the gloves before airtightness detection are usually stacked in a relatively random and messy manner, and due to the soft body characteristics of the gloves themselves, it is difficult to straighten each glove into the same posture and put it on the support structure through structures such as manipulators; while the manual operation method has disadvantages such as high labor cost and low work efficiency, and cannot meet the requirements of large-scale production.

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

[0006] The object of the present invention is to provide an automatic glove feeding and sorting system to solve the problems mentioned in the above background technology. When performing airtightness detection on gloves, the traditional manual operation method is required to separately take out each glove, adjust it to a specific posture and put it on the support structure. This method has the disadvantages of high labor cost and low work efficiency, and cannot meet the requirements of large-scale production.

[0007] The present invention is implemented by the following technical solutions:

[0008] An automatic glove feeding and sorting system includes a feeding mechanism and a sorting mechanism. The feeding mechanism is used to separately feed each glove into 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. Among them, the feeding mechanism includes a storage part and a picking part, and the sorting mechanism includes a pneumatic posture correction part and a receiving part. The picking part is used to separately take out each glove from the storage part, and the taken-out glove will reach the pneumatic posture correction part to receive posture correction. After the posture is corrected, the glove will reach the receiving part in a specific posture.

[0009] In the above solution, by setting the feeding mechanism and the sorting mechanism, the system can automatically complete the whole process of glove picking, posture correction and positioning, so as to facilitate the subsequent airtightness detection of gloves. Among them, the storage part is used to temporarily store the disordered gloves, the picking part is used to take out the gloves from the storage part one by one, the taken-out gloves will then reach the pneumatic posture correction part to receive posture correction, and 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 airtightness detection.

[0010] Further, the storage part includes a displacement component and a storage bin. The top of the storage bin is provided with a discharge port, and the storage bin moves on the horizontal plane with the displacement component. The picking part includes a lifting component and a picking member. The picking member is located above the discharge port of the storage bin, and the picking member moves up and down with the lifting component.

[0011] In the above solution, by setting up the lifting component, the material taking part can enter the storage bin to take materials and leave the storage bin to feed materials (to the pneumatic attitude correction part), and can take materials from gloves at different height positions in the storage bin; by setting up the displacement component, the storage bin can move on the horizontal plane, so that the material taking part can take materials from gloves at different horizontal positions; therefore, the material taking part only needs to perform a linear lifting motion to complete the material taking 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 taking part, and setting the specific positions of the various structures in the storage part and the material taking part, it is necessary to ensure that there is no misalignment between the material taking part and the storage bin during the horizontal movement of the storage bin, that is, the material taking part can always successfully descend into the storage bin to take materials.

[0012] Further, the displacement component includes a translation structure and a rotation structure. The translation structure includes a translation power member and a translation plate driven by the translation power 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.

[0013] In the above solution, under the action of the rotation power member, the slewing bearing can drive the storage bin to perform a rotational motion; and under the action of the translation power member, the translation plate can indirectly drive the storage bin to perform a translational motion by driving the slewing bearing; thus, based on the combined motion of the translation structure and the rotation structure, gloves at different positions in the storage bin all pass through the material taking part, and then the material taking operation for all gloves in the storage bin can be realized.

[0014] Further, the material taking part is a rod-shaped member with a hollow interior and evacuated to form a vacuum. The lifting component includes a lifting power member and a wheel set driven by the lifting power member. The wheel set includes a driving wheel and a pressing wheel as a driven wheel. The driving wheel and the pressing wheel are respectively arranged on both sides of the material taking part and are both in contact with the surface of the material taking part.

[0015] In the above solution, under the drive of the lifting power member, the wheel set will rotate and then generate a frictional force with the material taking part. Under the action of the frictional force, the material taking rod can perform a lifting motion; among them, when the material taking rod descends to contact the gloves in the storage bin, it will receive an upward external force that stops the material taking rod from descending, and because the inner lumen of the material taking rod is in a negative pressure state, the gloves will be adsorbed onto the material taking rod.

[0016] Further, the pneumatic attitude 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. The air acceleration mechanism is connected and communicated with the air channel tube. The material channel component includes a feed channel and a discharge channel respectively connected and communicated with the air channel tube. The discharge channel is communicated below the air channel tube through the air acceleration mechanism. When the pneumatic attitude correction part corrects the attitude of the glove, the glove first enters the air channel tube from the feed channel under the action of an external force. After the external force is removed, the upper port of the air channel tube is closed, and at the same time, the air acceleration mechanism generates an accelerating air flow downward along the circumferential direction of its inner wall.

[0017] In the above solution, the pneumatic correction component is used to correct the attitude of the glove by forming an air flow, 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 accelerating air flow, and the air channel tube is used to cooperate with the air acceleration mechanism. Based on this, the glove can be rotated in the pneumatic correction component through the air flow, and thus the attitude correction of the glove can be completed.

[0018] Further, the air channel tube includes an outer shell. The inside of the outer shell is hollow, and its top and bottom are provided with openings. An opening and closing baffle is provided on the upper part of the outer shell. The bottom end of the outer shell is communicated with the air acceleration mechanism.

[0019] In the above solution, the opening and closing baffle can automatically switch between the open and closed states, and thus can change the air flow situation in the air channel tube.

[0020] Further, 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 communicated 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.

[0021] In the above solution, after the air acceleration mechanism is started, compressed air is sent into the air storage chamber. The compressed air is accelerated through the acceleration channel to form an accelerating air flow that moves downward along the circumferential direction of the inner wall of the air acceleration mechanism and flows out downward from the air flow outlet. During 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 air flow. The center of the air acceleration mechanism is the hollow chamber. Since the air flow flowing upward into the hollow chamber is relatively low-speed and high-pressure, while the accelerating air flow moving downward along the circumferential direction of the inner wall of the air acceleration mechanism is relatively high-speed and low-pressure, the air flow flowing upward into the hollow chamber will approach the accelerating air flow, thereby forming a curved eddy current with upward flow at the center and downward flow at the side wall. When the glove in a random posture passes through the position where the curved eddy current is formed, it will rotate under the action of the curved eddy current until the glove becomes a posture with the wrist opening facing downward and the fingers facing upward.

[0022] Further, a breathable barrier is provided between the air acceleration mechanism and the opening and closing baffle.

[0023] In the above solution, the breathable barrier is used to limit the height of the glove.

[0024] Further, the receiving part is located below the discharge channel. The receiving part includes a receiving component and a glove fixture. The receiving component includes a plurality of receiving claws distributed in a central divergent shape. The plurality of receiving claws move closer to or away from each other under the drive of the opening and closing drive member and move up and down under the drive of the lifting drive member. The glove fixture is located between or below the plurality of receiving claws.

[0025] In the above solution, the receiving claws are used to receive and spread open the glove falling from the discharge channel and assist the glove to be sleeved on the glove fixture. Specifically: the initial positions of the plurality of receiving claws are above the glove fixture. The plurality of receiving claws first move closer to each other so that the glove falls in a posture with the wrist opening facing downward and the fingers facing upward, and then the plurality of receiving claws are located inside the glove. Then, the plurality of receiving claws move away from each other to spread open the wrist part of the glove. Then, the plurality of receiving claws move downward with the state of moving away from each other to make the glove sleeved on the glove fixture (when the plurality of receiving claws are in the state of moving away from each other, the gap between them is sufficient to avoid the glove fixture). Then, the plurality of receiving claws move closer to each other and then continue to move downward to take off the glove, so that the glove remains on the glove fixture. Finally, the plurality of receiving claws will reset to the initial position.

[0026] Further, a signal detection device for detecting whether the glove passes through is provided in the discharge channel.

[0027] In the above solution, by setting the signal detection device to detect whether the glove falls from the discharge channel, the receiving claws can be linked to act accordingly.

[0028] The beneficial effects achieved by the present invention are as follows:

[0029] A glove automatic feeding and sorting system is provided. By setting a feeding mechanism and a sorting mechanism, and setting the sorting mechanism to include a pneumatic posture correction part, the whole process of glove material taking, posture correction, and positioning can be automatically completed; among them, the posture correction is efficiently achieved in a pneumatic and non-contact manner. Compared with the prior art that requires traditional manual operation methods, the present invention realizes automation, thereby effectively reducing labor costs, improving production quality and production efficiency, and thus being well applicable to large-scale production requirements.

[0048] Based on the above structure, the glove automatic feeding and sorting system provided in this embodiment can perform its work according to the following three basic steps: "material taking → attitude correction → positioning", specifically:

[0049] Ⅰ. In the material taking step:

[0050] The disordered gloves are temporarily stored in the storage bin 201. Under the action of the lifting component, the material taking part 101 can descend to the storage bin 201 to pick up a single glove from the storage bin 201, and then ascend to the handover position with the pneumatic attitude 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 pick up gloves at different horizontal positions. Among them:

[0051] When the lifting component acts to enable the material taking part 101 to pick up materials, the following specific steps are included:

[0052] 1) Driven by the lifting power part, the driving wheel 102, the guiding wheel 104 and the pressing wheel 103 rotate respectively according to the driving wheel rotation direction a, the guiding wheel rotation direction b and the pressing wheel rotation direction c as shown. When the three wheels rotate, frictional forces will be generated between them and the material taking rod, and thus the material taking rod can descend by relying on the frictional force. Figure 2 As shown, when the material taking rod descends to contact the gloves in the storage bin 201, it will receive an upward external force that stops the material taking rod from descending. And because the inner cavity of the material taking rod is in negative pressure and there is an air flow direction d in the inner cavity of the material taking rod as shown, the gloves will be adsorbed onto the material taking rod.

[0053] 2) When the material taking rod descends to contact the gloves in the storage bin 201, it will receive an upward external force that stops the material taking rod from descending. And because the inner cavity of the material taking rod is in negative pressure and there is an air flow direction d in the inner cavity of the material taking rod as shown, the gloves will be adsorbed onto the material taking rod. Figure 2 As shown, when the material taking rod descends to contact the gloves in the storage bin 201, it will receive an upward external force that stops the material taking rod from descending. And because the inner cavity of the material taking rod is in negative pressure and there is an air flow direction d in the inner cavity of the material taking rod as shown, the gloves will be adsorbed onto the material taking rod.

[0054] 3) The lifting power part drives the driving wheel 102, the guiding wheel 104 and the pressing wheel 103 to reverse, so that the material taking rod can rise with the gloves until the gloves reach the handover position with the pneumatic attitude correction part 3; when the gloves enter the pneumatic attitude correction part 3 under the action of an external force, the execution starts from step 1) again for a new round.

[0055] When the displacement component acts to enable the storage bin 201 to move, the following specific actions are included: Driven by the rotary power part, the slewing bearing 203 rotates in the slewing bearing rotation direction e as shown; at the same time, driven by the translation power part, the translation plate 202 moves in the translation plate translation direction f as shown; thus, based on the combined movement of the slewing bearing 203 and the translation plate 202, the storage bin 201 moves in such a way that gloves at different positions therein can all pass under the material taking part 101. Figure 3 Shown, the slewing bearing 203 is driven by the rotary power part to rotate in the slewing bearing rotation direction e as shown; at the same time, the translation plate 202 is driven by the translation power part to move in the translation plate translation direction f as shown; thus, based on the combined movement of the slewing bearing 203 and the translation plate 202, the storage bin 201 moves in such a way that gloves at different positions therein can all pass under the material taking part 101. Figure 3 Shown, the slewing bearing 203 is driven by the rotary power part to rotate in the slewing bearing rotation direction e as shown; at the same time, the translation plate 202 is driven by the translation power part to move in the translation plate translation direction f as shown; thus, based on the combined movement of the slewing bearing 203 and the translation plate 202, the storage bin 201 moves in such a way that gloves at different positions therein can all pass under the material taking part 101.

[0056] Ⅱ. In the attitude correction step:

[0057] After the glove reaches the handover position with the pneumatic posture correction part 3 after the material taking step, the external force will send the glove into the pneumatic correction component through the feeding channel 301. Subsequently, the pneumatic correction component will automatically align the glove to a specific posture by forming an air flow. Finally, the glove in the specific posture will fall to the material receiving part 4 through the discharging channel 306. In this embodiment, the external force comes from the air amplifier arranged in the inclined pipe (the extended part of the feeding channel 301) between the material taking part and the pneumatic posture correction part. The air amplifier can eject compressed air flowing obliquely upward. Under the action of the compressed air, the glove will be sucked into the pneumatic correction component. In other embodiments, those skilled in the art can adopt other structures or methods to achieve the external force, and the present invention does not make special limitations on this.

[0058] The specific steps for the pneumatic correction component to perform work are as follows:

[0059] 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 pipe 304 circulates freely. When the glove reaches the handover position with the pneumatic posture correction part 3, the external force sends the glove into the feeding channel 301 according to the feeding air flow direction g as shown, and makes it pass upward through the hollow chamber 3051 of the air acceleration mechanism 305 (at this time, the air acceleration mechanism 305 is not started), and then reaches the air permeable barrier 303 in the air channel pipe 304 and is blocked by the air permeable barrier 303. Figure 4 As shown in the figure, the glove is sent into the feeding channel 301 and passes upward through the hollow chamber 3051 of the air acceleration mechanism 305 (at this time, the air acceleration mechanism 305 is not started), and then reaches the air permeable barrier 303 in the air channel pipe 304 and is blocked by the air permeable barrier 303.

[0060] 2) After the external force is cancelled, the opening and closing baffle 302 becomes closed. At this time, the air acceleration mechanism 305 is started, and the glove moves downward along the vertical direction due to the action of gravity. When the glove moves downward to pass through the air flow outlet 3055 of the air acceleration mechanism 305, the glove will rotate and finally automatically align to a specific posture. The specific principle for achieving this effect is as follows:

[0061] The compressed air is sent into the air storage chamber 3053 of the air acceleration mechanism 305 through the compressed air inlet 3052 according to the compressed air access direction h as shown. When the air acceleration mechanism 305 is started, the compressed air will be accelerated instantaneously through the acceleration channel 3054 to form an accelerating air flow flowing downward along the inner wall circumference of the air acceleration mechanism 305 (this accelerating air flow preferably reaches supersonic speed, and the principle is the Laval nozzle effect), and flows out downward from the air flow outlet 3055 according to the accelerating air flow direction i as shown in the figure and as shown in the figure. Figure 5 The compressed air is sent into the air storage chamber 3053 of the air acceleration mechanism 305 through the compressed air inlet 3052 according to the compressed air access direction h as shown. When the air acceleration mechanism 305 is started, the compressed air will be accelerated instantaneously through the acceleration channel 3054 to form an accelerating air flow flowing downward along the inner wall circumference of the air acceleration mechanism 305 (this accelerating air flow preferably reaches supersonic speed, and the principle is the Laval nozzle effect), and flows out downward from the air flow outlet 3055 according to the accelerating air flow direction i as shown. Figure 4 and Figure 5 As shown in the figure and as shown in the figure, the accelerating air flow flows out downward from the air flow outlet 3055.

[0062] 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 air flow. At the center of the air acceleration mechanism 305, that is, at the hollow chamber 3051, since the air flow flowing upward into the hollow chamber 3051 is relatively low-speed and high-pressure, and the accelerating air flow along the inner wall circumference of the air acceleration mechanism 305 downward is relatively high-speed and low-pressure, the air flow flowing upward into the hollow chamber 3051 will approach this accelerating air flow, and then a curved eddy current with upward flow at the center and downward flow at the side wall is formed. This curved eddy current has the same as Figure 4 and Figure 5 The curved eddy current flow direction j shown.

[0063] When the glove in a random posture passes through the position where the curved eddy current is formed, it will rotate under the action of the curved eddy current until the glove becomes a posture with the wrist opening facing down and the fingers facing up. At this time, the inner side of the glove bears the upward air flow, and the air passage tube 304 on the outer side of the glove is a negative pressure area. Therefore, the wrist opening of the glove can be in a stretched state, and the glove suspends at the air outlet 3055 position in this posture, thereby realizing the correction of the glove posture.

[0064] 3) After completing the correction of the glove posture, immediately the air acceleration mechanism 305 is closed, and the opening and closing baffle 302 becomes open again. The glove will fall into the discharge channel 306 under the action of its own gravity.

[0065] III. In the positioning step:

[0066] Four receiving claws 402 are used to receive and expand the glove falling from the discharge channel 306, and assist the glove to be sleeved on the glove fixture 401. Then, the four receiving claws 402 will reset to wait for receiving the next glove. The specific steps for the four receiving claws 402 to perform their work are as follows:

[0067] 1) The four receiving claws 402 are initially located at the initial position k as shown in Figure 6 . At this time, the four receiving claws 402 are in a position relationship of being close to each other, that is, in the closed state s as shown in Figure 7 ; when a glove falls after passing through the signal detection device 307, it will land on the receiving component with the wrist opening facing down and the fingers facing up. At this time, all four receiving claws 402 are located inside the glove; subsequently, under the linkage of the signal representing that the glove has fallen sent by the signal detection device 307, the opening and closing drive member will drive the four guide frames 403 to drive the four receiving claws 402 to move away from each other, that is, to change it to the open state t as shown in Figure 7 to expand the wrist of the glove.

[0068] 2) Then, the lifting drive member drives the mounting bracket 404 to move downward with the four material receiving claws 402 and the glove in the expanded state, so that the four material receiving claws 402 reach the sleeve die position l as shown in Figure 6 , and then the glove can be sleeved on the glove fixture 401; during 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 fixture 401.

[0069] 3) Then, the opening and closing drive member drives the four material receiving claws 402 to move closer to each other, that is, to change back to the closed state s again. Then, the lifting drive member drives the four material receiving claws 402 to move downward, so that the four material receiving claws 402 reach the demolding position m as shown in Figure 6 ; during this process, since the glove has been sleeved on the glove fixture 401, when the four material receiving claws 402 change to the closed state s, the glove does not descend with the material receiving claws 402 but remains on the glove fixture 401.

[0070] 4) Then, the opening and closing drive member drives the four material receiving claws 402 to move away from each other, that is, to change back to the open state t again. Then, the lifting drive member drives 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 cyclic action.

[0071] In summary, by performing the material taking step, the posture correction step and the positioning step, the disordered gloves in the storage bin 201 can be finally sleeved on the glove fixture 401 in a specific posture, so as to facilitate the subsequent airtightness detection. Based on this, the system provided in this embodiment realizes automation, which can effectively reduce the labor cost, improve the production quality and production efficiency.
