Description

Technical Field

[0001] The present invention relates to the technical field of glove packaging equipment, and in particular to a glove posture correction and conveying mechanism and a working method thereof. Background Art

[0002] Disposable gloves are a common type of personal protective equipment. They have the advantages of high elasticity, high air tightness, and good comfort. They have been widely used in various fields such as health care, food processing, and industrial manufacturing. In the production process of disposable gloves, they need to be tested for air tightness before packaging to determine whether the disposable gloves have defects such as gaps and damage.

[0003] When using the inflation method to test the air tightness of gloves, before filling the gloves with gas, it is often necessary to put the gloves on a special support structure in a specific posture. 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 external rubber gloves needs to be tested, the external rubber gloves are first put on the annular side of the truncated pedestal seat; however, neither of the above two patents discloses how to put the gloves on the glove fixing mechanism or the annular side of the truncated pedestal seat. In fact, investigations have found that because gloves are usually stacked in a random and messy manner before air-tightness testing, and because the gloves themselves are soft, it is difficult to use structures such as robotic arms to straighten each glove into the same posture and put it on the support structure; therefore, in most workshops, workers are required to manually straighten each glove and put it on the support structure in a specific posture. However, this method has the disadvantages of high labor costs and low work efficiency, and cannot be applied to large-scale production needs.

[0004] In summary, the present invention provides a glove posture correction and conveying mechanism and a working method thereof. Summary of the invention

[0005] The purpose of the present invention is to provide a glove posture correction and conveying mechanism and a working method thereof, so as to solve the following technical problems mentioned in the above background technology: when performing air tightness testing on gloves, it is necessary to manually adjust each glove 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.

[0006] The present invention is achieved by adopting the following technical solutions:

[0007] A glove posture correction and conveying mechanism comprises a material channel part and a pneumatic posture correction part, wherein the pneumatic posture correction part is connected with the material channel part; the material channel part is used to provide a channel for the glove to enter or leave the pneumatic posture correction part; the pneumatic posture correction part is used to adjust the posture of the glove; the pneumatic posture correction part comprises an air acceleration mechanism and an air channel tube located above the air acceleration mechanism; when the pneumatic posture correction part adjusts the posture of the glove, the glove first enters the air channel tube from the material channel part under the action of an 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.

[0008] Furthermore, the air acceleration mechanism is connected to the air channel tube; the material channel part 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.

[0009] 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.

[0010] 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.

[0011] Furthermore, an air-permeable barrier is provided between the air acceleration mechanism and the opening and closing baffle.

[0012] Furthermore, the opening and closing baffle is a butterfly valve.

[0013] A working method of a glove posture correction and conveying mechanism, using the above-mentioned glove posture correction and conveying mechanism, comprises the following steps:

[0014] Step 1: Under the action of external force, the glove passes through the material channel part and enters the pneumatic posture correction part;

[0015] Step 2: After the external force is removed, the upper port of the air channel tube is closed, and the glove rotates in the pneumatic posture correction part based on the airflow formed by the pneumatic posture correction part, and finally automatically finds a specific posture;

[0016] Step 3: The pneumatic posture correction part stops forming airflow, the upper port of the air channel tube opens, and the glove falls through the material channel part in a specific posture, and finally leaves the glove posture correction and conveying mechanism.

[0017] Furthermore, in step 1, the opening and closing baffle is in an open state; in step 2, the opening and closing baffle becomes a closed state, and the air acceleration mechanism is started to form an airflow; in step 3, the opening and closing baffle becomes an open state again, and the air acceleration mechanism is closed to stop forming an airflow.

[0018] Furthermore, after the air acceleration mechanism is started, the compressed air in the air storage chamber will be accelerated through the acceleration channel to form an accelerated airflow that flows downward along the circumference of the inner wall of the air acceleration mechanism and flows downward from the airflow outlet; in the process of the accelerated airflow flowing downward, the airflow flowing upward into the hollow chamber will approach the accelerated airflow.

[0019] Furthermore, in each step, the method of applying force to the gloves by the glove posture correction and conveying mechanism is as follows:

[0020] In step 1, the opening and closing baffle is in an open state, the air in the air channel tube flows freely, and the glove reaches the air channel tube under the action of external force;

[0021] In step 2, as the external force is removed, the opening and closing baffle becomes closed and the air acceleration mechanism is activated, the glove moves downward; when the glove moves downward to the airflow outlet position passing through the air acceleration mechanism, the glove rotates under the combined action of the accelerated airflow formed by the air acceleration mechanism and the airflow approaching the accelerated airflow; when the glove rotates to a posture with the wrist facing downward and the fingers facing upward, the inner side of the glove is subjected to the upward airflow, and the air channel tube outside the glove is in a negative pressure area, so that the glove is suspended at the airflow outlet position in this posture;

[0022] In step 3, as the opening and closing baffle becomes open again and the air acceleration mechanism is closed, the glove falls through the material channel portion under the action of its own gravity.

[0023] The beneficial effects achieved by the present invention are:

[0024] Provided is a glove posture correction and conveying mechanism and a working method thereof. By setting a material channel part and a pneumatic posture correction part, and based on steps 1 to 3 performed by the material channel part and the pneumatic posture correction part, the automatic posture correction and conveying of disordered gloves can be achieved in a pneumatic and contactless manner, thereby facilitating each glove to be put on a support structure in a specific posture in the subsequent process.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] Example 1

[0035] The first aspect of this embodiment provides a glove posture correction and conveying mechanism, please refer to Figure 1 and Figure 2 , including a material channel part and a pneumatic posture correction part, the pneumatic posture correction part is connected to the material channel part; the material channel part is used to provide a channel for the glove to enter or leave the pneumatic posture correction part, and the pneumatic posture correction part is used to adjust the posture of the glove. Specifically:

[0036] The pneumatic posture correction part includes an air acceleration mechanism 4 and a vertically arranged air channel tube 3 located above the air acceleration mechanism 4, and the air acceleration mechanism 4 is connected to the air channel tube 3; the material channel part includes a feed channel 6 and a discharge channel 5 respectively connected to the air channel tube 3, wherein the discharge channel 5 is vertically arranged and connected to the air channel tube 3 directly below the air channel tube 3 through the air acceleration mechanism 4. In this embodiment, the air acceleration mechanism 4, the air channel tube 3, the feed channel 6 and the discharge channel 5 are all cylindrical in shape (in other embodiments, they can be set to other shapes according to actual conditions, and the present invention does not make special restrictions on this); the feed channel 6 is connected to the discharge channel 5 in an inclined posture (in other embodiments, the feed channel 6 can be set at other positions according to actual conditions, and the present invention does not make special restrictions on this), and then connects the air acceleration mechanism 4 and the air channel tube 3.

[0037] The air channel tube 3 includes an outer shell, the interior of the outer shell is hollow and has openings at the top and bottom. The upper part of the outer shell is provided with an opening and closing baffle 1, and the bottom end is connected to the air acceleration mechanism 4. An air-permeable barrier 2 is provided between the air acceleration mechanism 4 and the opening and closing baffle 1 (those skilled in the art may select a baffle or a mesh with holes according to actual conditions, and the present invention does not make special restrictions on this). In this embodiment, the opening and closing baffle 1 specifically adopts a butterfly valve (in other embodiments, other components or other structures may be used as the opening and closing baffle 1 according to actual conditions, as long as the effect of automatically switching between the open and closed states can be achieved, and the present invention does not make special restrictions on this).

[0038] Please refer to Figure 3 The air acceleration mechanism 4 includes an annular main body portion 42, the inner side of the main body portion 42 is a hollow chamber 41, an annular air storage chamber 44 is provided in the main body portion 42, the air storage chamber 44 is connected to the compressed air inlet 43 located on the outer side thereof, and an annular acceleration channel 45 is connected below the air storage chamber 44 (in other embodiments, the structure of the acceleration channel 45 can also adopt a plurality of evenly distributed through holes, which is not particularly limited in the present invention), and an air flow outlet 46 is provided at the end of the acceleration channel 45, and the air flow outlet 46 faces the discharge channel 5.

[0039] A second aspect of the present embodiment provides a working method of a glove posture correction and conveying mechanism, which uses the above-mentioned glove posture correction and conveying mechanism and includes the following steps:

[0040] Step 1: Please refer to Figure 4, a single glove has a random posture in a natural state, the opening and closing baffle 1 is in an open state, and the airflow in the air channel tube 3 on the upper side of the air acceleration mechanism 4 flows freely; under the action of external force, the glove enters the mechanism through the feed channel 6, and passes upward through the hollow chamber 41 of the air acceleration mechanism 4 (the air acceleration mechanism 4 is not started at this time), and then reaches the air permeable barrier 2 in the air channel tube 3 and is blocked by the air permeable barrier 2. Among them, the external force can be specifically compressed air, which can send the glove into the air channel tube 3 from the entrance of the feed channel 6.

[0041] Step 2: Please refer to Figure 5 After the external force is removed, the opening and closing baffle 1 becomes closed, and the air acceleration mechanism 4 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 46 passing through the air acceleration mechanism 4, the glove rotates and finally automatically finds a specific posture. The specific method to achieve this effect is as follows:

[0042] Please refer to Figure 6 When the air acceleration mechanism 4 is started, the compressed air is sent into the air storage chamber 44 of the air acceleration mechanism 4 through the compressed air inlet 43. The compressed air will be instantly accelerated through the acceleration channel 45 to form an accelerated airflow downward along the inner wall of the air acceleration mechanism 4 (the accelerated airflow preferably reaches supersonic speed, the principle is the Laval nozzle effect), and flows downward from the airflow outlet 46; in this process, the pressure at the center of the air acceleration mechanism 4 becomes negative pressure, and the outside air enters the center of the air acceleration mechanism 4 to form an upward airflow. The center of the air acceleration mechanism 4 is the hollow chamber 41. Since the airflow flowing upward into the hollow chamber 41 is relatively low-speed and high-pressure, and the accelerated airflow flowing downward along the inner wall of the air acceleration mechanism 4 is relatively high-speed and low-pressure, the airflow flowing upward into the hollow chamber 41 will approach the accelerated airflow, thereby forming a curved vortex with the center pointing upward and the side wall pointing downward.

[0043] When the glove in a random posture passes through 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 3 outside the glove is a negative pressure area, so the glove wrist can be stretched. The glove is suspended at the position of the airflow outlet 46 in this posture, thereby achieving the correction of the glove posture.

[0044] Step 3: Please refer to Figure 7 After the posture correction of the gloves is completed, the air acceleration mechanism 4 is closed, and the opening and closing baffle 1 becomes open again. The gloves fall through the discharge channel 5 under the action of their own gravity, thereby completing the output of the gloves.

[0045] In summary, the glove posture correction and conveying mechanism and the working method thereof provided in this embodiment can realize automatic posture correction and conveying of disordered gloves in a pneumatic and contactless manner, so that each glove can be put on the support structure in a specific posture in the future; this pneumatic straightening method has the advantages of high efficiency, high degree of automation, and labor cost saving, and can be well applied to the large-scale production needs of disposable gloves.

[0046] It should be noted that the parts that are not described in detail or in detail in the above scheme, such as the specific way in which the external force is applied, how to realize the automatic start and shutdown of the air acceleration mechanism 4, how to realize the automatic opening and closing of the opening and closing baffle 1, etc., all use existing related technologies and do not belong to the improvements made to the existing technologies by the present invention to solve the technical problems to be solved, nor do they belong to the scope of protection of the technical scheme of the present invention. Therefore, they will not be repeated in this article.

[0047] Of course, the above contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of the embodiments of the present invention. The present invention is not limited to the above examples, and equal changes and improvements made by ordinary technicians in the technical field within the essential scope of the present invention should all fall within the scope of the patent coverage of the present invention.
