Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of lid conveying equipment, and more specifically, to a lid conveying device and a lid fastening production line having the same. Background Technology
[0002] After the powder is filled, a lid needs to be placed on the can to protect the powder inside. To facilitate the transport of the lids, multiple lids are usually placed in a box. When the lid is needed, multiple lids need to be removed and placed on the first conveyor belt.
[0003] In existing technology, multiple upright covers are sequentially placed on a first conveyor belt. A gripper sequentially clamps each cover and transfers it to a second conveyor belt, which then moves the covers to a capping machine. An upright cover refers to a cover whose axis is parallel to the horizontal plane. Since one gripper can only hold one cover at a time, a stop bar is installed at the exit of the first conveyor belt to prevent other covers from falling off. However, the contact area between the stop bar and the cover is small. Under the pressure of subsequent covers and the force of the first conveyor belt, the cover may tilt, potentially causing it to fall off the first conveyor belt. In other words, the stop bar is ineffective in stopping the cover. Utility Model Content
[0004] The main purpose of this utility model is to provide a cover conveying device and a cover fastening production line having the same, so as to solve the problem that the cover may fall off from the discharge end when the stop bar stops the cover in the related technology.
[0005] To achieve the above objectives, according to one aspect of the present invention, a cover conveying device is provided, comprising: a base frame; a first conveying structure disposed on the base frame and used for conveying covers, the first conveying structure having an inlet end and an outlet end; a stop structure disposed adjustablely at the outlet end of the first conveying structure, the stop structure including a stop plate having a stop position for stopping covers and a avoidance position for avoiding covers; and a first driving structure disposed on the base frame, the first driving structure drivingly cooperating with the stop plate to switch the stop plate between the stop position and the avoidance position.
[0006] Furthermore, the moving direction of the stop plate has a preset angle with the conveying direction of the first conveying structure.
[0007] Furthermore, the stop plate is provided with an avoidance notch, and when the stop plate is in the avoidance position, the cover moves out through the avoidance notch.
[0008] Furthermore, the cover conveying device also includes a second drive structure mounted on the base frame and a cover-removing structure that drives and cooperates with the second drive structure. The cover-removing structure has a cover-removing state and a release state. The second drive structure drives the cover-removing structure to switch between the cover-removing state and the release state. When the cover-removing structure is in the cover-removing state, the stop plate switches from the stop position to the avoidance position. When the cover-removing structure moves from the cover-removing state to the release state, the stop plate switches from the avoidance position to the stop position.
[0009] Furthermore, the cover conveying device also includes a transmission structure and a reversing structure. The transmission structure includes a transmission plate and a mounting rod. The first end of the transmission plate is driven and engaged with the second drive structure, and the second end of the transmission plate is connected to the mounting rod. The mounting rod extends along the width direction of the first conveying structure. The cover-removing structure is set on the mounting rod, and the reversing structure is set between the mounting rod and the base frame. When the cover-removing structure moves from the cover-removing state to the release state, the reversing structure drives the mounting rod to rotate.
[0010] Furthermore, the reversing structure includes a guide rod and a connector. The connector is rotatably mounted on the base frame. The rotation axis of the connector is parallel to the width direction of the first conveying structure. The connector is provided with a mounting through hole. The guide rod is connected to the mounting rod and passes through the mounting through hole.
[0011] Furthermore, the base frame has an outwardly protruding support member that extends in a direction away from the feed end, and the connector is rotatably mounted on the outwardly protruding support member.
[0012] Furthermore, the cover conveying device also includes a third drive structure, which is mounted on the mounting rod. The third drive structure works in conjunction with the cover-removing structure to move the cover-removing structure toward or away from the discharge end.
[0013] Furthermore, the first conveying structure includes multiple conveying components, which are spaced apart along the length of the stop plate. The clearance gaps are multiple, and each clearance gap corresponds to one of the multiple conveying components.
[0014] According to another aspect of the present invention, a cap-making production line is provided, including a cap conveying device and a second conveying structure. The cap conveying device is the cap conveying device described above, and the second conveying structure is disposed at the discharge end of the first conveying structure.
[0015] The cover conveying device of this utility model includes a base frame, a first conveying structure, a stop structure, and a first driving structure mounted on the base frame. The first conveying structure is used to convey the cover. The first conveying structure has an inlet end and an outlet end. The stop structure is located at the outlet end of the first conveying structure and includes a stop plate with a stopping position and a clearance position. When the stop structure is in the stopping position, it stops the cover; when the stop structure is in the clearance position, it clears the cover. Through the above arrangement, the cover can enter the first conveying structure from the inlet end and move to the outlet end under the drive of the first conveying structure. The stop plate can stop the cover, preventing it from falling from the outlet end. Compared to the stop rod in the prior art, the stop plate has a larger contact area with the cover, preventing the cover from falling from the outlet end when the stop plate is in the stopping position. The first driving structure can switch the stop plate between a stop position and a clearance position. When the stop plate is in the stop position, it limits the movement of the cover; when the stop plate is in the clearance position, it clears the cover, allowing the cover to move normally. Therefore, the technical solution of this application effectively solves the problem in related technologies where the cover may fall off the discharge end when the stop bar stops it.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0030] like Figure 1 and Figure 8 As shown, the cover conveying device of this embodiment includes: a base frame 10, a first conveying structure 20, a stop structure 30, and a first driving structure 40. The first conveying structure 20 is disposed on the base frame 10 and is used to convey the cover 1. The first conveying structure 20 has an inlet end 21 and an outlet end 22. The stop structure 30 is adjustablely disposed at the outlet end 22 of the first conveying structure 20. The stop structure 30 includes a stop plate 31, which has a stop position for stopping the cover 1 and a avoidance position for avoiding the cover 1. The first driving structure 40 is disposed on the base frame 10 and drives the stop plate 31 to switch the stop plate 31 between the stop position and the avoidance position.
[0031] Applying the technical solution of this embodiment, the cover conveying device includes a base frame 10, a first conveying structure 20, a stop structure 30, and a first driving structure 40 disposed on the base frame 10. The first conveying structure 20 is used to convey the cover 1. The first conveying structure 20 has an inlet end 21 and an outlet end 22. The stop structure 30 is disposed at the outlet end of the first conveying structure 20, and the stop structure 30 includes a stop plate 31, which has a stopping position and a clearance position. When the stop structure 30 is in the stopping position, the stop structure 30 stops the cover 1; when the stop structure 30 is in the clearance position, the stop structure 30 clears the cover 1. Through the above arrangement, the cover 1 can enter the first conveying structure 20 from the inlet end 21 and move to the outlet end 22 under the drive of the first conveying structure 20. A stop plate 31 is provided to stop the cover 1, preventing it from falling from the discharge end 22. Compared to the stop bar in the prior art, the contact area between the stop plate 31 and the cover 1 is larger, preventing the cover 1 from falling from the discharge end when the stop plate 31 is in the stop position. The first driving structure 40 can drive the stop plate 31 to switch between the stop position and the avoidance position. This ensures that when the stop plate 31 is in the stop position, it limits the movement of the cover 1; when the stop plate 31 is in the avoidance position, it avoids the cover 1, allowing the cover 1 to move normally. Therefore, the technical solution of this embodiment effectively solves the problem in the related art where the cover may fall from the discharge end when the stop bar stops the cover.
[0032] like Figure 1 and Figure 8 As shown, in this embodiment, the stop plate 31 is movably disposed on the base frame 10 along the height direction of the base frame 10. This simplifies the movement path of the stop plate 31 and facilitates the first drive structure 40 in driving the stop plate 31 to move.
[0033] In other embodiments, the stop plate 31 is rotatably mounted on the base frame 10. Of course, the stop plate 31 can also be moved along the width direction of the first conveying structure 20.
[0034] like Figure 1 and Figure 8 As shown, in this embodiment, the stop plate 31 is provided with a clearance notch 311. When the stop plate 31 is in the clearance position, the cover 1 moves out through the clearance notch 311. The cover 1 can move out through the clearance notch 311. That is, by providing the clearance notch 311, the stop plate 31 can move a small distance to achieve clearance of the cover 1.
[0035] The stop structure 30 also includes a mounting plate disposed on the side of the stop plate 31. The first drive structure 40 includes a first drive member and a connecting rod, wherein the telescopic rod of the first drive member is connected to the connecting rod, and the connecting rod is disposed on the mounting plate.
[0036] The connecting rod is set parallel to the mounting plate.
[0037] The first driving component is the first cylinder.
[0038] like Figures 2 to 4 As shown, in this embodiment, the cover conveying device further includes a second driving structure 50 disposed on the base frame 10 and a cover-removing structure 60 driven and cooperating with the second driving structure 50. The cover-removing structure 60 has a cover-removing state and a release state. The second driving structure 50 drives the cover-removing structure 60 to switch between the cover-removing state and the release state. When the cover-removing structure 60 is in the cover-removing state, the stop plate 31 switches from the stop position to the avoidance position. When the cover-removing structure 60 moves from the cover-removing state to the release state, the stop plate 31 switches from the avoidance position to the stop position. When the cover-removing structure 60 is in the cover-removing state, the cover-removing structure 60 can drive the cover 1 to move out from the discharge end 22. After the cover-removing structure 60 drives the cover 1 to move out from the discharge end 22, the second driving structure 50 can drive the cover-removing structure 60 to move to the release state, thereby realizing the transfer of the cover 1. When the cover-removing structure 60 is in the cover-removing state, the stop plate 31 switches from the stop position to the avoidance position, so that the cover-removing structure 60 can bring the cover 1 out of the discharge end 22. When the cover-removing structure 60 moves from the cover-removing state to the release state, the stop plate 31 switches from the avoidance position to the stop position to prevent the cover 1 on the first conveying structure 20 from falling off the first conveying structure 20.
[0039] The second drive structure 50 is a second cylinder, which is hinged on the base frame 10.
[0040] The cap-removing structure 60 is a suction cup. In other embodiments, the cap-removing structure 60 can be a gripper.
[0041] like Figures 1 to 6As shown, in this embodiment, the cover conveying device further includes a transmission structure 70 and a reversing structure 80. The transmission structure 70 includes a transmission plate 71 and a mounting rod 72. The first end of the transmission plate 71 is driven and engaged with the second drive structure 50, and the second end of the transmission plate 71 is connected to the mounting rod 72. The middle part of the transmission plate 71 is hinged to the base frame 10. The mounting rod 72 extends along the width direction of the first conveying structure 20. The cover-removing structure 60 is disposed on the mounting rod 72, and the reversing structure 80 is disposed between the mounting rod 72 and the base frame 10. When the cover-removing structure 60 moves from the cover-removing state to the release state, the reversing structure 80 drives the mounting rod 72 to rotate. The second drive structure 50 can drive the transmission plate 71 to move, which in turn drives the mounting rod 72 to move, and the mounting rod 72 can drive the cover-removing structure 60 to move. The reversing structure 80 is provided so that when the transmission plate 71 drives the mounting rod 72 to move, the mounting rod 72 can rotate relative to the transmission plate 71. In turn, the mounting rod 72 can drive the cover-removing structure 60 to rotate relative to the base frame 10 around the axis of the mounting rod 72, that is, to realize the reversing of the cover-removing structure 60.
[0042] The telescopic rod of the second cylinder is hinged to the first end of the transmission plate 71.
[0043] The axis of the mounting rod 72 is set parallel to the width direction of the first conveying structure 20.
[0044] The swing axis of the transmission plate 71 is set parallel to the width direction of the first conveying structure 20.
[0045] like Figure 4 and Figure 6 As shown, in this embodiment, the reversing structure 80 includes a guide rod 81 and a connector 82. The connector 82 is rotatably mounted on the base frame 10, and the rotation axis of the connector 82 is parallel to the width direction of the first conveying structure 20. The connector 82 is provided with a mounting through hole 821. The guide rod 81 is connected to the mounting rod 72 and passes through the mounting through hole 821. When the mounting rod 72 moves, it can drive the guide rod 81 to move within the mounting through hole 821. When the guide rod 81 moves, it can drive the connector 82 to rotate relative to the base frame 10, thereby enabling the rotation of the mounting rod 72. Consequently, the mounting rod 72 can drive the cover-removing structure 60 to rotate, that is, the mounting rod 72 can drive the cover-removing structure 60 to reverse direction.
[0046] The reversing structure 80 also includes a first connecting block that is fixedly connected to the guide rod 81. The mounting rod 72 passes through the first connecting block, and the relative position of the mounting rod 72 and the first connecting block remains fixed.
[0047] like Figure 1As shown, in this embodiment, the base frame 10 has a protruding support member 11, which extends in a direction away from the feed end 21, and the connector 82 is rotatably mounted on the protruding support member 11. The protruding support member 11 can support the connector 82, facilitating the installation of the connector 82.
[0048] The protruding support member 11 includes a connecting plate and a support plate. The connecting plate is perpendicular to the support plate and connects the support plate and the base frame 10. The support plate extends along the height direction of the base frame. The connecting member 82 is rotatably mounted on the support plate.
[0049] Connector 82 includes a second connecting block.
[0050] like Figure 4 and Figure 5 As shown, in this embodiment, the cover conveying device further includes a third driving structure 90, which is mounted on the mounting rod 72. The third driving structure 90 cooperates with the cover-removing structure 60 to move the cover-removing structure 60 toward or away from the discharge end 22. The third driving structure 90 enables the cover-removing structure 60 to move toward or away from the discharge end 22, thereby enabling the cover-removing structure 60 to contact the cover 1, complete the cover removal, and after removal, drive the cover 1 to move away from the discharge end 22, increasing the distance between the cover 1 and the discharge end 22, making it easier for the cover-removing structure 60 to drive the cover 1 to change direction.
[0051] The third drive structure 90 is the third cylinder, and the telescopic rod of the third cylinder is connected to the cover removal structure 60.
[0052] like Figure 1 and Figure 8 As shown, in this embodiment, the first conveying structure 20 includes multiple conveying components 23, which are spaced apart along the length of the stop plate 31. Multiple clearance notches 311 are also included, each corresponding to one of the multiple conveying components 23. The multiple conveying components 23 enable the simultaneous conveying of multiple covers 1. The one-to-one correspondence between the multiple clearance notches 311 and the multiple conveying components 23 facilitates the cover removal structure 60 removing the cover 1 when the stop plate 31 is in the clearance position.
[0053] The conveyor component 23 includes a first roller, a second roller, and a conveyor belt fitted around the outer periphery of the first and second rollers. One first roller, one second roller, and one conveyor belt constitute a set of conveyor substructures, and each conveyor component includes two sets of conveyor substructures. The first and second rollers are spaced apart and rotatably mounted on the base frame 10. The two sets of conveyor substructures are spaced apart along the length of the stop plate 31.
[0054] The length direction of the stop plate 31 is parallel to the width direction of the first conveying structure 20.
[0055] like Figures 5 to 8 As shown, the capping production line of this embodiment includes a cap conveying device and a second conveying structure 100. The cap conveying device is the one described above, and the second conveying structure 100 is disposed at the discharge end 22 of the first conveying structure 20. The stop plate 31 of the cap conveying device can stop the cap 1. Compared with the stop rod, the stop plate 31 has a larger contact area with the cap 1, preventing the cap 1 from falling from the discharge end of the first conveying structure 20. The can processing production line with the cap conveying device described above also has the above advantages.
[0056] The second conveying structure 100 includes a conveyor plate chain. Of course, in other embodiments, the second conveying structure may also be a conveyor belt or a conveyor roller.
[0057] The second conveying structure 100 drives the cover 1 to move in a direction parallel to the width direction of the first conveying structure 20. The second conveying structure 100 then drives the cover to the capping machine.
[0058] like Figure 7 and Figure 8 As shown, when the cover-removing structure 60 is in the cover-removing state, the axis of the cover-removing structure 60 is parallel to the length direction of the first conveying structure 20. The third drive structure 90 first drives the cover-removing structure 60 to move towards the direction closer to the discharge end 22. After the cover-removing structure 60 contacts the cover body 1, the third drive structure 90 drives the cover-removing structure 60 to move away from the discharge end 22. The second drive structure 50 then drives the mounting rod 72 to move the cover-removing structure 60. At the same time, the reversing structure 80 drives the cover-removing structure 60 to reverse direction.
[0059] like Figure 3 As shown, when the cap removal structure 60 switches from the cap removal state to the release state, the first drive structure 40 drives the transmission plate 71 to swing, and then the transmission plate 71 can drive the mounting rod 72 to move. When the mounting rod 72 moves, it can drive the guide rod 81 to slide in the mounting through hole 821, and then the guide rod 81 can drive the connecting piece 82 to rotate, ultimately realizing the movement of the cap removal structure 60.
[0060] like Figure 5 As shown, when the cap-removing structure 60 is in the released state, the reversing structure 80 has already driven the cap-removing structure 60 to complete the reversal, that is, the axis of the cap-removing structure 60 is perpendicular to the second conveying structure 100. The third driving structure 90 drives the cap-removing structure 60 to move towards the direction closer to the second conveying structure 100, and the cap-removing structure 60 drives the cap 1 closer to the second conveying structure 100, and the cap-removing structure 60 releases the cap.
[0061] In the description of this utility model, it should be understood that "multiple" means two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms 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, and therefore should not be construed as limiting the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.
[0062] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0063] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
[0064] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
