Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0036] like Figure 1 and Figure 3 As shown, the present application provides a conveying device. An embodiment of the conveying device of the present application includes: a first conveying portion 10 , a transfer mechanism 20 , a blocking mechanism 30 and a second conveying portion 40 . Among them, the first conveying part 10 extends along the first direction a, and the first conveying part 10 is used to carry and convey multiple cover bodies 1 stacked along the first direction a, wherein the cover body 1 located on the first conveying part 10 is in a vertical posture; the transfer mechanism 20 is arranged downstream of the first conveying part 10, and the transfer mechanism 20 can grab the cover body 1 and drive the cover body 1 to flip to a horizontal posture; the blocking mechanism 30 is arranged between the first conveying part 10 and the transfer mechanism 20, and the blocking mechanism 30 has a blocking position for limiting the movement of the cover body 1 along the first direction a and an avoidance position for avoiding the cover body 1 so that the cover body 1 can move along the first direction a. When the transfer mechanism 20 drives the cover body 1 to flip, the blocking mechanism 30 is in the blocking position; the second conveying part 40 extends along the second direction b, and the second conveying part 40 can receive and convey the cover body 1 grabbed by the transfer mechanism 20, wherein the second direction b is arranged to intersect with the first direction a.

[0037] By applying the technical solution of this embodiment, when it is necessary to place the cover body 1, the cover body 1 in a vertical posture is transported by the first conveying part 10 along the first direction a to the transfer mechanism 20, and then transferred by the transfer mechanism 20 to the second conveying part 40. When the transfer mechanism 20 transfers the cover body 1, it can make the cover body 1 flip from the vertical posture to the horizontal posture, so that the cover bodies 1 are placed one by one on the second conveying part 40 to facilitate subsequent capping operations. The blocking mechanism 30 is arranged between the first conveying part 10 and the transfer mechanism 20. When the transfer mechanism 20 grabs a cover body 1 and performs a flipping action, the blocking mechanism 30 can block the remaining cover bodies 1 on the first conveying part 10 to prevent the cover bodies 1 from falling, etc. Using the conveying device of this embodiment, the staff only needs to place the stacked caps 1 in a vertical position on the first conveying part 10. The staff can place multiple caps 1 on the first conveying part 10 in one operation, which greatly improves the staff's efficiency in placing the caps 1. The subsequent action of placing the caps 1 in a horizontal position on the second conveying part 40 is performed by the transfer mechanism 20, which improves the efficiency of placing the caps 1. Therefore, the technical solution of this embodiment can effectively solve the problem in the related art that the manual placement of the caps cannot meet the capping speed of the robot arm.

[0038] It should be noted that, in this embodiment, when the transfer mechanism 20 transfers the cover 1, the cover 1 located at the most downstream is transferred. In addition, the first direction a and the second direction b mentioned in this embodiment are both lateral directions, and the first direction a and the second direction b are set at an angle, preferably the first direction a is perpendicular to the second direction b. In addition, it should be noted that the first direction a and the second direction b of this embodiment refer to the movement directions of the cover 1 on the first conveying part 10 and the second conveying part 40, respectively. Specifically, the first direction a is Figure 1 The direction from top to bottom in the middle, the second direction b is Figure 1 In the direction from right to left.

[0039] Specifically, when it is detected that the cover body 1 is missing in the subsequent capping step, the conveying device of this embodiment can be started to convey the cover body 1 to perform the capping step. Specifically, the judgment of "missing the cover body 1" is made by the photoelectric detector. When it is detected that the cover body 1 is missing, a signal is given to the solenoid valve, and the solenoid valve controls the first cylinder 32, the second cylinder 53 and the driving cylinder 26 to act to realize the capping operation.

[0040] like Figure 4 and Figure 5As shown, the conveying device further includes a limiting mechanism 50 corresponding to the end of the first conveying part 10, and the limiting mechanism 50 has a limiting position and a separation position. When the limiting mechanism 50 is in the limiting position, it can limit the cover body 1 adjacent to the most downstream cover body 1 from moving along the first direction a. The limiting mechanism 50 can limit the cover body 1 adjacent to the most downstream cover body 1 from moving along the first direction a, so that when the transfer mechanism 20 grabs the cover body 1, it can only grab the cover body 1 located at the most downstream.

[0041] like Figure 6 and Figure 7 As shown, the transfer mechanism 20 includes a suction cup structure 21, which has a suction state extending in the lateral direction and opposite to the stacked multiple cover bodies 1 and a release state extending in the vertical direction and opposite to the second conveying part 40. The cover body 1 is grasped by the suction cup structure 21, which has the advantages of simple structure and easy control.

[0042] like Figure 6 and Figure 7 As shown, the suction cup structure 21 includes a suction rod 211 and a suction cup 212 arranged at the first end of the suction rod 211, and the transfer mechanism 20 also includes a driving rocker arm 22, a connecting rotating rod 23, a positioning block 24 and a guide rod 25. The connecting rotating rod 23 is rotatably connected to the upper end of the driving rocker arm 22, the positioning block 24 is rotatably arranged, the first end of the guide rod 25 is connected to the connecting rotating rod 23, and the second end of the guide rod 25 is movably penetrated through the positioning block 24. The second end of the suction rod 211 is connected to the connecting rotating rod 23. When the driving rocker arm 22 swings, it can drive the connecting rotating rod 23 to switch between a suction position corresponding to the positioning block 24 horizontally and a release position corresponding to the positioning block 24 vertically. When the connecting rotating rod 23 is located at the suction position, the suction cup structure 21 is in a suction state, and when the connecting rotating rod 23 is located at the release position, the suction cup structure 21 is in a release state.

[0043] It should be noted that the above-mentioned “suction position corresponding to the positioning block 24 laterally” refers to that the connecting rotating rod 23 is located between the positioning block 24 and the first conveying part 10 and is basically flush with the positioning block 24 in the height direction (not limited to the same height); the above-mentioned “release position corresponding to the positioning block 24 vertically” refers to that the connecting rotating rod 23 is located below the positioning block 24 and is basically flush with the positioning block 24 in the first direction (not limited to the two being on the same vertical line).

[0044] Specifically, in this embodiment, the transfer mechanism 20 includes two driving swing rods 22 arranged on both sides of the first conveying part 10, and the connecting rotating rod 23 is located between the two driving swing rods 22 and rotates with the tops of the two driving swing rods 22. The transfer mechanism 20 also includes a driving cylinder 26, which is drivingly connected to the lower end of the driving swing rod 22 to drive the driving swing rod 22 to swing. When the driving swing rod 22 swings, the connecting rotating rod 23 located at the upper end of the driving swing rod 22 switches between the suction position and the release position. When the connecting rotating rod 23 moves from the release position to the suction position, due to the existence of the guide rod 25, the connecting rotating rod 23 rotates while moving, thereby driving the suction rod 211 connected thereto to swing so that the suction cup structure 21 can move to the suction state; when the connecting rotating rod 23 moves from the suction position to the release position, due to the existence of the guide rod 25, the connecting rotating rod 23 rotates while moving, thereby driving the suction rod 211 connected thereto to swing so that the suction cup structure 21 can move to the release state.

[0045] Preferably, the suction rod 211 and the guide rod 25 have the same extension trend, that is, the suction rod 211 and the guide rod 25 are arranged in parallel or at a small angle.

[0046] like Figure 6 and Figure 7 As shown, the suction cup structure 21 includes a suction rod 211 and a suction cup 212 arranged on the suction rod 211. The suction rod 211 includes a first rod body 2111 and a second rod body 2112 which are nested and matched. The suction cup 212 is arranged at one end of the first rod body 2111 away from the second rod body 2112. When the suction cup structure 21 is in the suction state, the first rod body 2111 extends relative to the second rod body 2112 to drive the suction cup 212 to fit with the cover body 1. In the process of switching the suction cup structure 21 from the release state to the suction state, the first rod body 2111 retracts relative to the second rod body 2112, so that the suction cup structure 21 can move smoothly to avoid interference with the cover body 1; after the suction cup structure 21 is in the suction state, the first rod body 2111 extends relative to the second rod body 2112 to make the suction cup 212 fit on the cover body 1, so as to facilitate the suction action of the cover body 1.

[0047] like Figure 1 and Figure 7 As shown, the first conveying part 10 includes a plurality of conveying groups 101 extending along the first direction a, each conveying group 101 can convey a group of multiple cover bodies 1 arranged in a stacked manner, and the transfer mechanism 20 includes a plurality of suction cup structures 21 corresponding to the plurality of conveying groups 101. By providing a plurality of conveying groups 101 and a plurality of suction cup structures 21 corresponding to the plurality of conveying groups 101, the conveying efficiency can be further improved.

[0048] like Figures 1 to 4As shown, each conveying group 101 includes a first conveying belt 11 and a second conveying belt 12 arranged at intervals, and a placement space 13 is formed between the first conveying belt 11 and the second conveying belt 12. The stack of cover bodies 1 is conveyed by the first conveying belt 11 and the second conveying belt 12 arranged at intervals, which has the advantage of simple structure. Specifically, in this embodiment, the first conveying belt 11 and the second conveying belt 12 are both annular belt structures, and the first conveying part 10 also includes support ribs extending along the first direction a, and support ribs are provided below the upper belt parts of the first conveying belt 11 and the second conveying belt 12.

[0049] like Figure 4 and Figure 5 As shown, the blocking mechanism 30 includes a baffle 31 movably arranged in the up-down direction. When the blocking mechanism 30 is in the blocking position, the baffle 31 and the cover body 1 are at least partially overlapped. When the blocking mechanism 30 is in the avoidance position, the baffle 31 and the cover body 1 are separated in the up-down direction. The baffle 31 that moves up and down is used to block the cover body 1, which has the advantages of simple structure and easy control. Specifically, the blocking mechanism 30 also includes a first cylinder 32, which is arranged above the baffle 31 and can drive the baffle 31 to move in the up-down direction.

[0050] like Figure 3 As shown, the limiting mechanism 50 includes a first clamping portion 51 and a second clamping portion 52 arranged at intervals. When the limiting mechanism 50 is located at the limiting position, the first clamping portion 51 and the second clamping portion 52 are close to each other and can clamp the cover body 1 adjacent to the most downstream cover body 1. Specifically, when the transfer mechanism 20 grabs the cover body 1, the first clamping portion 51 and the second clamping portion 52 are close to each other and can respectively clamp the two sides of the cover body 1 adjacent to the most downstream cover body 1, so that the transfer mechanism 20 can only grab the cover body 1 located at the most downstream; after the transfer mechanism 20 completes the grabbing, the first clamping portion 51 and the second clamping portion 52 are moved away from each other to release the clamped cover body 1, so that the cover body 1 on the first conveying portion 10 can further move along the first direction a.

[0051] Specifically, the limiting mechanism 50 further includes a second cylinder 53, which can drive the first clamping portion 51 and / or the second clamping portion 52 to move, thereby clamping or releasing the cover body 1. Preferably, the second cylinder 53 is a bidirectional cylinder, which can simultaneously drive the first clamping portion 51 and the second clamping portion 52 to move.

[0052] like Figure 1As shown, the first conveying part 10 also includes a frame 14, the first conveyor belt 11, the second conveyor belt 12 and the transfer mechanism 20 are all installed on the frame 14, the conveying device also includes a mounting plate 60 arranged between the first conveying part 10 and the transfer mechanism 20, and the blocking mechanism 30 and the limiting mechanism 50 are both installed on the mounting plate 60.

[0053] Specifically, in this embodiment, the frame 14 is made of white steel pipes and white steel plates, and mounting groove wheels are provided at both ends of the frame 14. Both ends of the first conveyor belt 11 are respectively installed in a pair of mounting groove wheels, and both ends of the second conveyor belt 12 are respectively installed in a pair of mounting groove wheels. The first conveying part 10 also includes a motor, which can drive the first conveyor belt 11 and the second conveyor belt 12 to rotate.

[0054] like Figure 1 and Figure 2 As shown, the second conveying part 40 includes a third conveying belt 41 and a guide positioning member 42. The third conveying belt 41 has a first conveying section 411 and a second conveying section 412 located downstream of the first conveying section 411. The first conveying section 411 corresponds to the first conveying part 10, and the guide positioning member 42 corresponds to the second conveying section 412. Specifically, the guide positioning member 42 includes two guide positioning strips 421 arranged on both sides of the second conveying section 412. In the direction from the first conveying section 411 to the second conveying section 412, the distance between the two guide positioning strips 421 first gradually decreases, and then the distance between the two remains unchanged. The distance is equal to or slightly larger than the diameter of the cover body 1, so that the connecting line of the centers of the multiple cover bodies 1 conveyed by the second conveying part 40 is roughly a straight line, which is convenient for the subsequent grabbing of the cover body 1 for capping operation.

[0055] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0056] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0057] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0058] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
