Technical Field

[0001] The utility model relates to the field of material handling, in particular to a through-type transfer structure and a material handling system. Background Art

[0002] During the material handling process, it is necessary to transfer materials between different working areas. Sometimes, there are differences in the requirements for the working environments of different working areas.

[0003] Therefore, how to carry out cross-region handling has become a difficulty in material handling. To solve such problems, the existing methods provide a conveying structure for passing through a wall.

[0004] For example, the structure disclosed in the patent with the application publication number CN105197530A uses two conveyors that are docked and distributed in two working areas to transfer materials between the two areas.

[0005] However, in this structure, when the material is transferred from one working area to another, the states of the material at both ends of the conveyor are the same, which is not convenient for subsequent manual material taking for materials with manual operation handles, such as wafer boxes. Summary of the Utility Model

[0006] The purpose of the utility model is to solve the above problems existing in the prior art, and provide a through-type transfer structure and a material handling system.

[0007] The purpose of the utility model is achieved by the following technical solutions:

[0008] The through-type transfer structure includes a first docking port located in the first area and a second docking port located in the second area. A transfer mechanism is arranged between the first docking port and the second docking port. The transfer mechanism is used to transfer materials between the first docking port and the second docking port, and the transfer mechanism includes a tray and a mechanism for driving the tray to translate between the first docking port and the second docking port and rotate horizontally around an axis extending in the vertical direction.

[0009] Preferably, the first docking port includes an outer frame. A first operation port corresponding to one end of the transfer mechanism is arranged on the side of the outer frame. A carrier plate corresponding to the first operation port is arranged inside the outer frame. The carrier plate is located above the tray and has an avoidance port corresponding to the tray. A first detection sensor for detecting whether there is a material at the carrier plate is arranged inside the outer frame.

[0010] Preferably, positioning guiding blocks are arranged on the carrier plate so that the materials are positioned at a predetermined position on the carrier plate and can be transferred by the transfer mechanism.

[0011] Preferably, a detection grating is provided at the first operation port.

[0012] Preferably, a controller is provided on the outer frame on the same side as the first operation port.

[0013] Preferably, a second operation port corresponding to the carrier plate is provided at the top of the outer frame.

[0014] Preferably, a second detection sensor for detecting whether there is material within a certain range above the carrier plate is provided at the outer frame.

[0015] Preferably, there are two first operation ports, and each first operation port is matched with a transfer mechanism and a third operation port of a second pair of interfaces.

[0016] Preferably, the transfer mechanism includes a translation mechanism, on which a lifting mechanism driven by it to translate is provided, on the lifting mechanism a rotating mechanism driven by it to lift is provided, and on the rotating mechanism a tray driven by it to rotate horizontally is provided.

[0017] A material handling system includes the through-type transfer structure as described in any one of the above.

[0018] The advantages of the technical solution of the present utility model are mainly reflected in:

[0019] The transfer mechanism of the present utility model enables the material to be transferred between the first pair of interfaces and the second pair of interfaces, and at the same time enables the tray to rotate horizontally, so that the handle on the material can be rotated to a position adapted to the operator after the material is transferred, thus facilitating the subsequent manual picking and placing of the material by the operator and being beneficial to improving the operation convenience.

[0029] Embodiment 1

[0030] The following describes the through - type transfer structure disclosed by the present utility model with reference to the drawings. As shown in the attached Figure 1 and attached Figure 2 figures, it includes a first pair of interfaces 100 located in the first region and a second pair of interfaces 200 located in the second region. A transfer mechanism 300 is arranged between the first pair of interfaces 100 and the second pair of interfaces 200. The transfer mechanism 300 is used to transfer the material 500 between the first pair of interfaces 100 and the second pair of interfaces 200. The transfer mechanism 300 includes a tray and a mechanism for driving the tray to translate between the first pair of interfaces and rotate horizontally around an axis extending in the vertical direction.

[0031] Among them, the structures of the first pair of interfaces 100 and the second pair of interfaces 200 can be designed according to needs. Their structures can be different or the same. Preferably, the structures of the first pair of interfaces 100 and the second pair of interfaces 200 are the same.

[0032] Taking the first pair of interfaces 100 as an example for illustration below, the first pair of interfaces 100 includes an outer frame 110. The outer frame 110 can be a structure that is hollow inside and generally rectangular parallelepiped formed by columns, cross - beams and closing plates. As shown in the attachedFigure 3 As shown, a first operation opening 111 corresponding to one end of the transfer mechanism 300 is provided on the side of the outer frame 110. Correspondingly, the first operation opening 111 is provided on the side of the outer frame 110 facing away from the wall 400 or partition. A carrier plate 120 corresponding to the first operation opening 111 is provided inside the outer frame 110. The carrier plate 120 is used to carry the material 500. At the same time, in order to facilitate the transfer of the material 500 by the transfer mechanism 300, the carrier plate 120 has an avoidance opening 121 corresponding to the tray 310 of the transfer mechanism 300. And a first detection sensor (not shown in the figure) for detecting whether there is a material 500 at the carrier plate 120 is provided inside the outer frame 110. The first detection sensor can be a known proximity sensor or the like, and its installation position can be designed according to needs and is not limited here.

[0033] As attached Figure 3 As shown, in order to accurately align the material 500 at the carrier plate 120 with the tray 310 of the transfer device, a positioning guide block 130 is further provided on the carrier plate 120. The positioning guide block 130 includes two C-shaped blocks symmetrically distributed on both sides of the avoidance opening 121 and with opposite openings. The upper top corners inside the two C-shaped blocks are chamfered, and the two C-shaped blocks define a rectangular groove.

[0034] As attached Figure 1 、As attached Figure 3 As shown, a controller is provided on the outer frame 110. The controller and the first operation opening 111 are on the same side of the outer frame 110, which is convenient for the operator. The controller includes a display screen 140. The display screen 140 can be a known touch screen. At the same time, the controller further includes a transfer start button 150, an emergency stop button 160, a speaker 170, etc. When the operator places the material 500 on the carrier plate 120, the first detection sensor detects that there is a material 500 on the carrier plate 120. At this time, a prompt that the material 500 is in place can be issued through the speaker 170 and / or the display screen 140. Then, the operator can press the transfer start button 150 to trigger the transfer mechanism 300 to perform the transfer.

[0035] As attached Figure 1 As shown, a second operation opening 112 corresponding to the carrier plate 120 is provided at the top of the outer frame 110. The operation opening is used to cooperate with a top transfer mechanism 300 such as an overhead crane for work.

[0036] As attached Figure 3As shown, a detection grating 180 is provided at the first operation port 111 for detecting whether there is a staff member performing the operation of picking and placing the material 500. If so, the top transfer mechanism 300 can be controlled to stop picking and placing the material 500 from the second operation port 112. In addition, to conveniently control the movement of the top transfer mechanism 300, as shown in the appendix Figure 2 As shown, a second detection sensor 190 for detecting whether there is a material 500 within a certain range above the carrier plate 120 is provided on the outer frame 110. The second detection sensor 190 can be a proximity sensor, a through-beam sensor, a self-reflective sensor, etc. provided at a certain height above the carrier plate 120. Details are not elaborated here, and its specific installation position can be designed according to needs and is not limited here.

[0037] As shown in the appendix Figure 1 As shown, to facilitate distinguishing the entry and exit of the material 500, there are two first operation ports 111 at the first docking port 100, which are arranged side by side. Each first operation port 111 is matched with a transfer mechanism 300 and a third operation port of the second docking port 200. One of the first operation ports 111 serves as an inlet, and the other first operation port 111 serves as an outlet.

[0038] The structure of the second docking port 200 is the same as that of the first docking port, and details are not elaborated here. The second docking port and the first docking port are symmetrically distributed on both sides of the wall body 400 or the partition.

[0039] The structure of the transfer mechanism 300 can be designed according to needs. In this embodiment, as shown in the appendix Figure 4 As shown, the transfer mechanism 300 includes a translation mechanism 320, on which a lifting mechanism 330 driven by it to translate is provided. On the lifting mechanism 330, a rotating mechanism 340 driven by it to lift is provided. On the rotating mechanism 340, a tray 310 driven by it to rotate horizontally is provided.

[0040] The translation mechanism 320 can be a feasible device or structure capable of driving the rotating mechanism 340 to reciprocate linearly. For example, the translation mechanism 320 is a servo module. Preferably, as shown in the appendix Figure 4As shown, the translation mechanism 320 includes a moving frame 321 movably arranged on a track 322. The moving frame 321 can be arranged on the track 322 by rolling with rollers or by sliding with sliders. The structure of the moving frame 321 can be designed as required and is not limited herein. A driving wheel 324 driven to rotate by itself by a first motor 323 is arranged on the moving frame 321. The first motor 323 can be a known reduction motor. The axis of the driving wheel 324 extends horizontally and is perpendicular to the track 322. The driving wheel 324 is in rolling connection with a driving belt 325 that is fixedly positioned and extends along the moving direction of the translation mechanism 320. Both ends of the driving belt 325 are fixed on a belt fixing seat. When the first motor 323 drives the driving wheel 324 to rotate by itself, due to the driving belt 325 being fixed, the frictional force between them drives the moving frame 321 to move along the track 322. More preferably, in order to ensure stable contact between the driving wheel 324 and the driving belt 325, a limiting wheel 326 is further arranged on the moving frame 321 on both sides of the driving wheel 324 to make the driving belt 325 closely adhere to the driving wheel 324. The limiting wheel 326 is a belt wheel. The driving belt 325 bypasses the top of the driving wheel 324 after passing around the bottom of the limiting wheel 326 on one side and then passes around the top of the limiting wheel 326 on the other side. Of course, in other embodiments, the driving belt 325 can also pass around the top of the driving wheel 324 after passing around the top of the limiting wheel 326 on one side and then pass around the top of the limiting wheel 326 on the other side. Arranging the limiting wheel 326 can effectively increase the wrap angle between the driving belt 325 and the driving wheel 324, thereby ensuring the reliability and stability of the translation drive.

[0041] The structure of the lifting mechanism can also be set as required. For example, the lifting mechanism includes a hydraulic cylinder or a pneumatic cylinder. The telescopic shaft of the hydraulic cylinder or the pneumatic cylinder is connected to a lifting platform. A longitudinal guiding structure is arranged between the lifting platform and the moving frame 321. In a more preferred embodiment, as shown in the appendix Figure 5 As shown, in order to make the structure more compact and small, the lifting mechanism includes a lifting frame 331 slidably arranged vertically on the moving frame 321. A rack 332 extending vertically is arranged on the lifting frame 331. The rack 332 meshes with a gear 333. The gear 333 is connected to a second motor 334 that drives it to rotate by itself. The second motor 334 is a reduction motor and is fixed on the moving frame 321.

[0042] The rotation mechanism 340 can be a known servo turntable. More preferably, as shown in the appendix Figure 4As shown, the rotating mechanism 340 includes a pedestal bearing 342 provided on the lifting frame 331. The bottom of the pedestal bearing 342 is connected to a third motor 341. The third motor 341 is a reduction motor and is connected to the rotating shaft on the pedestal bearing 342. The top of the rotating shaft is connected to the center position at the bottom of the tray 310.

[0043] The shape of the tray 310 can be adaptively designed according to the material 500 to be transferred. In this embodiment, the tray 310 is a triangular plate, and positioning pins 311 matching the material 500 are provided on the tray 310. The positioning pins 311 are arranged at the three vertex positions of the tray 310.

[0044] After an operator places the material 500 on the carrier plate 120 and sends a transfer trigger signal, the transfer mechanism 300 moves the tray 310 to directly below the material 500. Then, the lifting mechanism drives the tray 310 to rise. The positioning pins 311 on the tray 310 are inserted into the positioning grooves or holes at the bottom of the material 500 to achieve the positioning of the material 500. At the same time, the rising carrier plate 120 lifts the material 500 above the positioning guide block 130. Then, the translation mechanism 320 drives the tray 310 to translate above the carrier plate 120 at the other end. After the rotating mechanism 340 drives the tray 310 to rotate 180° self - rotatably, the lifting mechanism drives the tray 310 to lower, thereby placing the material 500 on the carrier plate 120 at the other end. At this time, the operator takes away the material 500 on the carrier plate 120 at the other end. When the first detection sensor at the first interface or the second interface detects that there is a material transferred by the transfer mechanism on the carrier plate, the speaker can emit a voice or a prompt tone to remind the operator to process it. Of course, in other embodiments, the rotation angle of the tray can also be adjusted according to the position of the operation port, which is not limited herein.

[0045] Embodiment 2

[0046] This embodiment discloses a material handling system, including the through - type transfer structure as described above. The through - type transfer structure can cooperate with a known overhead crane system.

[0047] There are still various implementation manners of the present utility model. All technical solutions formed by equivalent transformation or equivalent substitution fall within the protection scope of the present utility model.
