The orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc. mentioned or possibly mentioned in this specification are defined with respect to the structures shown in the respective drawings. The terms "inside" and "outside" respectively refer to the directions towards or away from the geometric center of a specific component. They are relative concepts and may therefore change accordingly depending on their different positions and usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0034] The present application provides a cross-station material transfer device, including: a conveyor unit 1, a first material unit 2, a second material unit 3, and a third material unit 4.

[0035] Please refer to Figure 1, the conveying unit 1 includes a first conveying track 10, a second conveying track 11, and a third conveying track 12 arranged in sequence. The first conveying track 10, the second conveying track 11, and the third conveying track 12 are all inclined downward along the conveying direction of the material, facilitating the conveyance by means of its own gravity and increasing the transmission efficiency. The first conveying track 10 and the second conveying track 11 are spaced apart to facilitate the placement of the second material unit 3 described below. There is a height difference at the connection of the first conveying track 10 and the second conveying track 11, so that the material transmission starting points of the first conveying track 10 and the second conveying track 11 both have a certain height, facilitating the setting of inclined planes for material conveyance on the first conveying track 10 and the second conveying track 11. The second conveying track 11 and the third conveying track 12 define an arc-shaped bend at the connection, or the third conveying track 12 is an arc-shaped track. Through the bending of the arc-shaped bend or the arc-shaped track, the transmission direction of the material is changed to facilitate the conveyance of the material to different positions.

[0036] The first material unit 2 is located at the first end of the first conveying track 10 and is provided with a first placement table 20 that can be lifted and lowered. The first placement table 20 can be lifted to the opening at the first end of the first conveying track 10, so that the material on the first placement table 20 can automatically flow to the first end of the first conveying track 10.

[0037] The second material unit 3 is located between the first conveying track 10 and the second conveying track 11 and is provided with a second placement table 30 that can be lifted and lowered. Figure 5 The optional position of the second material unit 3 relative to the first conveying track 10 is shown. The second placement table 30 can be lifted to the opening at the second end of the first conveying track 10 to receive the material on the first conveying track 10. When the second placement table 30 is lifted to the opening at the first end of the second conveying track 11, the material on the second placement table 30 automatically flows to the first end of the second conveying track 11, and the material on the second conveying track 11 flows to the third conveying track 12 through the connection of the second conveying track 11 and the third conveying track 12.

[0038] The third material unit 4 is located at the second end of the third conveying track 12 and is provided with a third placement table 40 that can be lifted and lowered. When the third placement table 40 is lifted to the opening of the third conveying track 12, the material on the third conveying track 12 automatically flows to the third placement table 40.

[0039] Among them, the second conveying track 11 and the third conveying track 12 can be connected by means of abutting at the ports, facilitating the smooth transmission of materials from the second conveying track 11 to the third conveying track 12.

[0040] The cross-station material transfer equipment provided by this application, when it is necessary to transfer materials, first place the materials on the first placement table 20 of the first material unit 2, and then the first placement table 20 drives the materials to move to the corresponding height, so that they slide into the first conveying track 10 and continue to slide until they slide into the second material unit 3. Then, the second material unit 3 moves the materials to the corresponding height again, so that they slide into the second conveying track 11 and continue to slide, and enter the arc bend or arc track through the second conveying track 11 and finally enter the third material unit 4. The third material unit 4 can move it to the appropriate height. By setting the first conveying track 10, the second conveying track 11 and the third conveying track 12 to cooperate with the first material unit 2, the second material unit 3 and the third material unit 4, the materials of the first material unit 2 can be conveyed to the second material unit 3 and the third material unit 4, so as to realize the transfer of materials between different stations, solve the problem that the units for placing materials and the units for receiving materials need to correspond one by one, improve the material transfer efficiency, reduce the labor intensity, and there is no need to leave staff for material transfer at each station, saving the conveying cost.

[0041] As an optional embodiment, the conveying unit 1 further includes a frame body 13, and the frame body 13 includes a first support 130, a second support 131 and a third support 132; the first material unit 2 further includes a first base 21 fixed on the first support 130, and a first driving member 22 for driving the first placement table 20 to lift is installed on the first base 21; the second material unit 3 further includes a second base 31 fixed on the second support 131, and a second driving member 32 for driving the second placement table 30 to lift is installed on the second base 31; the third material unit 4 further includes a third base 41 fixed on the third support 132, and a third driving member 42 for driving the third placement table 40 to lift is installed on the third base 41. As Figure 2 、 Figure 6 and Figure 9 shown, the first support 130, the second support 131 and the third support 132 can be rectangular frame structures arranged vertically. The first base 21 can be fixedly connected to the first support 130 by bolts, welding, etc. The first driving member 22 is fixedly installed on the first support 130 to play a fixing role. The second base 31 can be fixedly connected to the second support 131 by bolts, welding, etc. The second driving member 32 is fixedly installed on the second support 131 to play a fixing role. The third base 41 can be fixedly connected to the third support 132 by bolts, welding, etc. The third driving member 42 is fixedly installed on the third support 132 to play a fixing role.

[0042] Among them, the first driving member 22, the second driving member 32, and the third driving member 42 can all be cylinder structures, and their vertically arranged output shafts can respectively drive the first placing table 20, the second placing table 30, and the third placing table 40 connected to the top to slide vertically.

[0043] As an alternative embodiment, the first support 130 includes at least two first vertical support rods 1300; the first material unit 2 further includes a moving frame 23 connected to the first driving member 22, and the moving frame 23 includes at least two sliding sleeves 230, and at least two of the sliding sleeves 230 are respectively sleeved on at least two of the first vertical support rods 1300 in a one-to-one correspondence. Please refer to Figure 2 and Figure 3 , the number of the first vertical support rods 1300 can be four, and the sliding sleeves 230 are correspondingly arranged as four. The four sliding sleeves 230 are respectively sleeved on the four first vertical support rods 1300 in a one-to-one correspondence, so that the moving frame 23 can slide smoothly within the first support 130.

[0044] The second support 131 includes at least two second vertical support rods 1310, and the second material unit 3 further includes a movable frame 33 connected to the second driving member 32. The movable frame 33 includes at least two pulley groups 330, and at least two of the pulley groups 330 are respectively abutted against the second vertical support rods 1310 in a one-to-one correspondence. Please refer to Figure 6 and Figure 7 , any one of the pulley groups 330 of the second vertical direction includes three vertically arranged pulleys, and the pulleys of any one of the pulley groups 330 can be abutted against the inner side of the second vertical support rod 1310, so as to avoid the situation that when the second placing table 30 slides vertically on the second support 131, the movable frame 33 arranged on the outer side of the second support 131 interferes with the second end opening of the first conveying track 10 and the first end opening of the second conveying track 11.

[0045] As an alternative embodiment, the first placing table 20 is rotatably connected to the moving frame 23, and a baffle 200 for preventing materials from falling off is arranged at one end of the first placing table 20 away from the first conveying track 10; a limiting elastic member 24 is connected between one side of the first placing table 20 away from the first conveying track 10 and the moving frame 23. Please refer to Figure 3 , the rotation axis of the first placing table 20 is located on a positioning shaft 201 fixed to the moving frame 23. A rotating sleeve 202 is arranged at the bottom of the first placing table 20, and the rotating sleeve 202 is rotatably connected to the positioning shaft 201 and can drive the first placing table 20 to rotate. The limiting elastic member 24 is in a compressed state. When there is no material on the first placing table 20, the elastic action of the limiting elastic member 24 balances the gravity of the baffle 200, so that the first placing table 20 is in a horizontal or approximately horizontal state.

[0046] Optionally, the rotation axis of the first placement table 20 is set on the side away from the first conveying track 10 (the position between the center line of the first placement table 20 and the end away from the first conveying track 10). When the material is placed on the first placement table 20, since the rotation axis is close to the side of the baffle 200, the first placement table 20 will incline downward toward the side of the baffle 200; or, when feeding the material on the first placement table 20, the material is placed on the side close to the baffle 200, and the first placement table 20 inclines downward toward the side of the baffle 200 and is stably set on the first placement table 20 under the block of the baffle 200.

[0047] Optionally, please refer to Figures 3 to 4 , a rotating frame 25 is connected between the lower part of the first placement table 20 and the moving frame 23, and a rotating sleeve 202 is arranged under the rotating frame 25. The limiting elastic member 24 can be a limiting spring, and the limiting spring is connected between the rotating frame 25 and the moving frame 23.

[0048] As an alternative embodiment, a limiting member is arranged on the side of the first placement table 20 facing the first conveying track 10. When the limiting member is lifted to contact the blocking member on one side of the first conveying track 10, it is limited and drives the first placement table 20 to incline toward the direction where the first conveying track 10 is located, so that the material on the first placement table 20 flows to the first conveying track 10. When the first placement table 20 is lifted to the position where the limiting member contacts the bottom of the first conveying track 10 or the blocking members such as blocks and baffles arranged around the first conveying track 10, the side of the first placement table 20 facing the first conveying track 10 is limited and guides the first placement table 20 to flip toward the side of the first conveying track 10, automatically flowing the material on the first placement table 20 onto the first conveying track 10.

[0049] As an alternative embodiment, a plurality of spherical seats are arranged on the third conveying track 12 configured as an arc-shaped track, and an outwardly convex ball 120 is arranged on the top of the spherical seat, and the ball 120 is rotatably arranged. As Figure 8 shown, after the ball 120 protruding from the top of the spherical seat contacts the material, it rotates to enable the material to smoothly pass along the bending direction of the arc-shaped track.

[0050] In addition, rollers arranged along the material conveying direction are arranged on both the first conveying track 10 and the second conveying track 11. Coupled with the fact that the first conveying track 10 and the second conveying track 11 are inclined along the material transmission direction, the material can be stably conveyed on the first conveying track 10 and the second conveying track 11.

[0051] As an optional embodiment, the third material unit 4 further includes a linkage assembly 43 located between the third conveying track 12 and the third placing table 40; the linkage assembly 43 includes a limiting platform 430 which is rotatably arranged to rotate towards the third placing table 40 after receiving the material on the third conveying track 12, so as to transfer the material on the limiting platform 430 to the third placing table 40. As Figures 9 to 10 shown, the limiting platform 430 receives a single material from the third conveying track 12 and transfers it to the third placing table 40 one by one, realizing the one-by-one transmission, picking and placing of the material between the third placing table 40 and the third conveying track 2.

[0052] As an optional embodiment, the linkage assembly 43 further includes a fixedly arranged support 431 and a link assembly 432 rotatably connected to the support 431. The link assembly 432 includes a first linkage rod 4320 and a second linkage rod 4321 which are bent and connected. The first linkage rod 4320 is connected to the limiting platform 430, and the second linkage rod 4321 extends towards the side where the third placing table 40 is arranged. When the third placing table 40 rises to make its side wall abut against the second linkage rod 4321, the second linkage rod 4321 is squeezed to drive the limiting platform 430 to tilt towards the third placing table 40, so that the material on the limiting platform 430 is transferred to the third placing table 40. As Figure 9 and Figure 10 shown, the support 431 is fixed on the frame 13. The first linkage rod 4320 can be an "L"-shaped rod, and the second linkage rod 4321 is an inclined rod. A bushing is arranged at the connection between the two. The bushing rotating sleeve 202 is sleeved on the limiting shaft 433 of the support 431 and can rotate around the limiting shaft 433. The side of the second linkage rod 4321 facing the third placing table 40 is free. When the third placing table 40 rises to contact the second linkage rod 4321 at its side, it plays a role in squeezing the second linkage rod 4321. The second linkage rod 4321 moves downward, thereby driving the limiting platform 430 to tilt towards the third placing table 40, and further conveying the material on the limiting platform 430 to the third placing table 40.

[0053] Furthermore, a sensor (such as a pressure sensor, an image sensor, etc.) for detecting whether there is material on the limiting platform 430 is arranged on the top of the limiting platform 430. When the sensor detects that there is material on the limiting platform 430, it transmits an ascending signal to the third driving member 42, and the third driving member 42 drives the third placing table 40 to rise.

[0054] Further, the side portion of the third storage table 40 can be an inclined surface, which starts squeezing the second linkage rod 4321 from the end contacting the second linkage rod 4321, and increases the lateral squeezing distance of the third storage table 40 as the third storage table 40 rises, so as to increase the inclination degree of the limiting platform 430.

[0055] Further, the third material unit 4 further includes a sliding frame 44 connected to the third driving member 42. The sliding frame 44 includes at least two pulley groups 330, and at least two of the pulley groups 330 are in one-to-one correspondence and abut against the side wall of the third support 132.

[0056] As an alternative embodiment, the top surface of the second storage table 30 is inclined in the same direction as the inclination directions of the first conveying track 10 and the second conveying track 11, so as to facilitate receiving the materials on the first conveying track 10 and conveniently conveying the materials on the first conveying track 10 to the second conveying track 11. At least two limiting rods that can be telescopically arranged in the vertical direction are installed on the second storage table 30, and when the two limiting rods extend, they limit the materials located on the second storage table 30. Among them, the limiting rods can be driven by a cylinder installed on the second storage table 30. When there are materials on the second storage table 30, the limiting rods are controlled to extend, and retract when the second storage table 30 is conveyed to the first end opening of the second conveying track 11.

[0057] Among them, the number of the limiting rods can be two, and the two limiting rods are respectively located on both sides of the second storage table 30; the number of the limiting rods can also be three, four, etc., and are arranged along the circumferential direction of the second storage table 30.

[0058] Further, an image sensor can be provided on the second storage table 30 to detect whether there are materials on the second storage table 30 and whether the second storage table 30 moves to the second end opening of the second conveying track 11, and transmit an extension signal to the controller of the cylinder when detecting the materials, and the cylinder drives the limiting rods to extend to prevent the materials from falling off the second storage table 30; when detecting that the second storage table 30 moves to the second end opening of the second conveying track 11, transmit a retraction signal to the controller of the cylinder, and the cylinder drives the limiting rods to retract, and the materials are transmitted to the second conveying track 11 under the action of gravity.

[0059] The present application also provides a material transmission method, which conveys materials through the cross-station material transmission device described in any one of the above embodiments, including the following steps.
