Description

Technical Field

[0001] This utility model relates to the field of disposable glove packaging, specifically to an alternating feeding mechanism for disposable gloves and a disposable glove folding machine. Background Technology

[0002] Disposable gloves are a type of glove made of thin rubber sheets or films. They are commonly used in industries where gloves are changed frequently to prevent cross-infection. Currently, disposable gloves are also prevalent in daily life, such as in the food service industry. For ease of use, existing gloves are typically folded together and packaged separately. Therefore, manufacturers need to stack two gloves together before folding and packaging them manually or mechanically. During glove feeding, current feeding devices can only pick up one glove at a time. Therefore, the device needs to travel back and forth twice to stack two gloves together before folding and packaging, resulting in slow feeding speed and impacting overall packaging efficiency. Utility Model Content

[0003] To address the aforementioned problems, this invention provides an alternating feeding mechanism for disposable gloves and a disposable glove folding machine.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] An alternating feeding mechanism for disposable gloves includes a carrier plate and picking modules respectively disposed on the left and right sides of the carrier plate. The front end of the carrier plate serves as the feeding end, and the carrier plate has a storage area. Each picking module on both sides includes a translation drive unit, a picking unit, and a lifting drive unit. The driving end of the lifting drive unit is connected to a horizontal support plate extending in the front-back direction. The picking unit is movably mounted on the translation drive unit and is supported on the horizontal support plate by at least its own weight. The translation drive unit drives the picking unit to move back and forth, so that the picking unit switches between the feeding end and the storage area. The lifting drive units of the picking modules on both sides drive the picking unit to rise and fall, so that the picking units on both sides are at different height positions, thereby achieving alternating movement.

[0006] Furthermore, the material handling unit is equipped with pulleys, which abut against the horizontal support plate.

[0007] Furthermore, the material handling unit includes a lifting driver, a connecting rod, and a material handling head. The lifting driver is movably mounted on the translation driving unit. The driving end of the lifting driver is connected to the connecting rod, which is located above the carrier plate. The material handling head is mounted on the connecting rod.

[0008] Furthermore, the material-taking head is a vacuum suction head, and there are multiple material-taking heads. The connecting rod is provided with an installation slot, and the multiple material-taking heads are assembled in the installation slot and their positions are adjustable.

[0009] Furthermore, the driving end of the translation drive unit is connected to a mounting plate, the mounting plate is provided with a vertical guide rail, and the material handling unit is equipped with a slider, which is slidably mounted on the vertical guide rail.

[0010] Furthermore, it also includes a raw material table, which is located at the front end of the carrier plate as a feeding end.

[0011] Furthermore, it also includes a raw material platform lifting drive unit, which is connected to the raw material platform to drive the raw material platform to move up and down.

[0012] Furthermore, the carrier plate also has a folding working area located at the rear end of the storage area, and also includes a movable claw clamp disposed at the rear end of the carrier plate. The movable claw clamp is movable back and forth to transfer the gloves located in the storage area to the folding working area.

[0013] Furthermore, the translation drive unit includes a translation driver and a horizontal transmission assembly extending forward and backward. The material picking unit is movably and vertically mounted on the horizontal transmission assembly. The translation driver drives the horizontal transmission assembly to drive the material picking unit on the horizontal transmission assembly to switch back and forth between the front end of the carrier plate and the storage area of ​​the carrier plate.

[0014] A disposable glove folding machine includes a feeding mechanism and a folding mechanism located at the rear end of the feeding mechanism, wherein the feeding mechanism is the aforementioned alternating feeding mechanism for disposable gloves.

[0015] The technical solution provided by this utility model has the following beneficial effects:

[0016] Material handling modules are set on the left and right sides of the carrier plate. The material handling unit is used to pick up and put down gloves. The translation drive unit drives the material handling unit to switch between the front end of the carrier plate and the storage area of ​​the carrier plate to transfer the gloves from the feeding end to the storage area. The cooperation of the lifting drive unit and the horizontal support plate can control the height of the material handling unit on the same side so that the material handling units on both sides will not interfere with each other during the alternating picking and putting of materials, realizing alternating feeding, which can effectively save the glove feeding time and improve the feeding efficiency.

These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0022] In the description of this invention, terms such as "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0024] Reference Figures 1 to 4As shown, this embodiment provides an alternating feeding mechanism for disposable gloves, including a carrier plate 10, a raw material platform 30, and material picking modules 20 respectively disposed on the left and right sides of the carrier plate 10. The front end of the carrier plate 10 serves as the feeding end 101. Specifically, the raw material platform 30 is disposed at the front end of the carrier plate 10, i.e., the raw material platform 30 is the feeding end 101. The carrier plate 10 has a storage area 102. The material picking modules 20 on both sides each include a translation drive unit 21, a picking unit 23, and a lifting drive unit 22. The driving end of the lifting drive unit 22 is connected to a horizontal support plate 221 extending in the front-back direction. The picking unit 23 is movably and vertically disposed on the translation drive unit 21 and abuts against the horizontal support plate 221 by its own weight. That is, when the lifting drive unit 22 drives the horizontal support plate 221 to rise, it will drive the picking unit 23 to rise synchronously. When the lifting drive unit 22 drives the horizontal support plate 221 to fall, the picking unit 23 falls down due to its own weight and abuts against the horizontal support plate 221. The translation drive unit 21 drives the picking unit 23 to move back and forth, so that the picking unit 23 switches between the front end of the carrier plate 10 (i.e., the feeding end 101) and the storage area of ​​the carrier plate. During the back and forth movement of the picking unit 23, the horizontal support plate 221 always provides support for the picking unit 23, that is, the picking unit 23 always abuts against the horizontal support plate 221. The lifting drive units 22 of the picking modules 20 on both sides drive the picking units 23 to rise and fall, so that the picking units 23 on both sides are at different height positions and thus achieve alternating movement.

[0025] For ease of subsequent description, the translation drive unit 21, the picking unit 23, and the lifting drive unit 22 of the left picking module 20 are defined as the left translation drive unit, the left picking unit, and the left lifting drive unit, respectively, and the translation drive unit 21, the picking unit 23, and the lifting drive unit 22 of the right picking module 20 are defined as the right translation drive unit, the right picking unit, and the right lifting drive unit, respectively.

[0026] One preferred operating mode of the alternating feeding mechanism is as follows: In the left-side material handling module 20, the left-side translation drive unit moves the left-side material handling unit to the feeding end 101, the left-side lifting drive unit descends to a low position, and the left-side material handling unit descends accordingly, picking up one glove 1 at a time from the material table 30. Afterwards, the left-side translation drive unit moves the left-side material handling unit backward to the storage area 102 and places the glove 1 in the storage area. During this backward movement, the right-side lifting drive unit of the right-side material handling module drives the right-side material handling unit to move upward to make way. The right-side translation drive unit moves the right-side picking unit forward to the feeding end 101. Then, the right-side lifting drive unit descends to a lower position, and the right-side picking unit descends accordingly to pick up material from the raw material table 30. Afterward, the right-side translation drive unit moves the right-side picking unit backward to the storage area 102 to release the material. During this process, the left-side lifting drive unit drives the left-side picking unit to move upward to make way and then forward to the feeding end 101. This process is repeated alternately to achieve alternating feeding. Every two layers of gloves stacked in the storage area can be output to the subsequent folding station (i.e., the folding work area 103 described below). This effectively saves glove feeding time and improves feeding efficiency. In practical applications, it is nearly twice as efficient as a single picking module, saving half the feeding time.

[0027] Furthermore, in actual operation, the raw material platform 30 holds a stack of gloves of a certain thickness (e.g., hundreds of layers thick). To facilitate the material handling by the material handling unit 23, a raw material platform lifting drive unit 40 is also included. This unit drives the raw material platform 30, causing it to move up and down. Specifically, when the raw material is thick, the lifting drive unit 40 lowers the platform to facilitate the material handling by the material handling unit 23. As the material thickness decreases, the lifting drive unit 40 raises the platform to maintain it at a reasonable height for stable material handling by the material handling unit 23. The lifting drive unit 40 can utilize existing technologies such as electric telescopic rods or lifting cylinders to achieve lifting and driving.

[0028] In this embodiment, a raw material platform 30 is set at the front end of the carrier plate 10 as the feeding end 101. Of course, in other embodiments, the front end of the carrier plate 10 can also be connected to the output end of a glove punching machine. After the glove punching machine punches out gloves, the gloves are output to the front end of the carrier plate 10 and then picked up by the material picking unit 23.

[0029] The material handling unit 23 includes a lifting driver 231, a connecting rod 232, and a material handling head 233. The lifting driver 231 is movably mounted on the translation drive unit 21. A pulley 234 is provided on the lifting driver 231, and the pulley 234 abuts against the horizontal support plate 221 to reduce friction and facilitate smoother forward and backward translation of the material handling unit 23. In this embodiment, the lifting driver 231 is a lifting cylinder. The driving end of the lifting driver 231 is connected to the connecting rod 232, which is located above the carrier plate 10. In this embodiment, the connecting rod 232 extends in the left-right direction. Two material handling heads 233 are provided and are respectively mounted on the connecting rod 232. Specifically, the connecting rod 232 is provided with an mounting slot 235. The two material handling heads 233 are mounted in the mounting slot 235 and their positions are adjustable. Thus, the spacing between the material handling heads 233 can be adjusted according to actual conditions to achieve better material handling. More specifically, the material-picking head 233 is a vacuum suction head that uses negative pressure to pick up the outermost layer of the material, specifically a glove 1, for greater precision. Of course, the structure of the material-picking unit 23 is not limited to this; for example, the material-picking head 233 can also be other structures, such as a clamping type, and the number of material-picking heads 233 can be one or more. The lifting driver 231 can also be directly abutted against the horizontal support plate 221, and so on.

[0030] The translation drive unit 21 includes a translation driver 211 and a horizontal transmission assembly 212 extending forward and backward. The material picking unit 23 is movably mounted on the horizontal transmission assembly 212. The translation driver 211 drives the horizontal transmission assembly 212 to drive the material picking unit 23 on the horizontal transmission assembly 212 to switch back and forth between the front end of the carrier plate 10 and the storage area 102 of the carrier plate 10. For example, the translation driver 211 can be a drive motor, and the horizontal transmission assembly 212 can be a horizontally arranged conveyor belt with a fixing block 213. Further, the fixing block 213 serves as the drive end of the translation drive unit 21. A mounting vertical plate 241 is connected to the fixing block 213, and a vertical guide rail 242 is provided on the mounting vertical plate 241. The material picking unit 23 is equipped with a slider 243, which is slidably mounted on the vertical guide rail 242, thereby realizing the lifting and lowering of the material picking unit 23. The drive motor drives the conveyor belt, which in turn drives the fixed block 213 and the material handling unit 23 to move back and forth.

[0031] Specifically, the material-picking unit 23 rests against the horizontal support plate 221 by its own weight, which is sufficient. Of course, in other embodiments, in order to make the lifting and lowering movements of the material-picking unit 23 and the horizontal support plate 221 more synchronized, an elastic element can be added. This elastic element applies a downward elastic force to the material-picking unit 23. When the horizontal support plate 221 descends, the material-picking unit 23 descends by its own weight and the elastic force applied by the elastic element. In this way, the continuity will be better, and the resistance generated between the vertical guide rail 242 and the slider 243 will be avoided, which would cause the material-picking unit 23 to descend in a lag.

[0032] The carrier plate 10 also has a folding working area 103 located at the rear end of the storage area 102, and includes a movable gripper 50. The movable gripper 50 is disposed at the rear end of the carrier plate 10 and can move back and forth to transfer the gloves located in the storage area 102 to the folding working area 103 for subsequent folding operations. The back and forth movement of the movable gripper 50 can be driven by a drive device similar to the translation drive unit 21. Of course, in other embodiments, the storage area 102 can also be directly used as the folding working area 103.

[0033] This embodiment also provides a disposable glove folding machine, including a feeding mechanism and a folding mechanism located at the rear end of the feeding mechanism, the feeding mechanism and the folding mechanism being mounted on the same machine platform. The feeding mechanism is the aforementioned alternating feeding mechanism for disposable gloves, and the folding mechanism performs folding operations on the gloves 1 transferred to the folding work area 103. Specifically, the folding mechanism can adopt a structure from the prior art, which will not be described in detail here.

[0034] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
