[0032] In view of the deficiencies in the prior art, the inventor of this case has proposed the technical solution of the utility model after long-term research and extensive practice. The technical solution, its implementation process and principle will be further explained as follows.

[0033] The technical solution, its implementation process and principles, etc. will be further explained below in conjunction with the accompanying drawings and specific implementation cases. Unless otherwise specified, the cylinder, cover body, cans, motors, chains, belts, etc. used in the embodiments of the utility model are components known to those skilled in the art, which can be purchased commercially, and their specific structures and models are not limited here.

[0034] See also Figure 1-Figure 7 As shown, one embodiment of the utility model proposes a cover body detection device, including a constraint mechanism and a detection mechanism 2, wherein the constraint mechanism at least includes a first limiting mechanism and a second limiting mechanism that are relatively arranged, and the first limiting mechanism and the second limiting mechanism enclose a constraint space for constraining the grouped cover bodies 7; the detection end of the detection mechanism 2 is arranged opposite to the end of the grouped cover bodies 7 in the constraint space, and is used to identify whether the end of the grouped cover bodies 7 is a positive end or a negative end.

[0035] For easy understanding, see Figure 1 and Figure 2 The utility model provides a cover detection device which can be placed downstream of the cover buffer and the transfer device to carry the grouped covers 7 that have been bagged and packaged. The grouped covers 7 can be dropped or placed in the constrained space. The detection end of the detection mechanism 2 can be opposite to the end of the grouped covers 7 and detect the end of the grouped covers 7. It is easy to understand that the grouped covers 7 are formed by stacking a plurality of covers in sequence. Due to the particularity of the shape of the cover itself, the sheet-like cover has a front side and a back side. The front side of the cover can be understood as the side on which the pull ring can be pulled, and the back side of the cover is the side connected to the body of the can. Then, the grouped covers 7 stacked in sequence have a positive end and a reverse end.

[0036] The cover detection device provided by the utility model is actually used to detect and identify the positive end and the reverse end of the grouped cover 7, so that the subsequent stacking process can be stacked in order according to the designated end of the grouped cover 7. One end of the grouped cover 7 placed in the constrained space can be opposite to the detection mechanism 2, and the detection mechanism 2 can identify and detect whether this end is the positive end or the reverse end. In the subsequent stacking, the detected end can be stacked in order according to whether it is the positive end or the reverse end.

[0037] Furthermore, if Figure 1 and Figure 2 As shown, the detection end of the detection mechanism 2 is arranged crosswise with the axis of the grouped cover body 7, that is, the detection end of the detection mechanism 2 can detect the grouped cover body 7 from the side of the grouped cover body 7. Since the first cover body or the last cover body of the grouped cover body 7 is prone to reverse cover phenomenon during the packaging process, that is, the arrangement direction of this cover body is opposite to that of other cover bodies, the detection mechanism 2 arranged on the side of the grouped cover body 7 can also detect the first cover body or the last cover body at the end, detect and determine whether the first cover body or the last cover body is reversed. It is easy to understand that the detection mechanism 2 is provided at at least one of the first limiting mechanism and the second limiting mechanism, and the end of the grouped cover body 7 can be detected by one side, or both ends of the grouped cover body 7 can be detected to improve the detection accuracy. Of course, the detection mechanism 2 can be a proximity sensor. Since the front and back surfaces of the cover body have different shapes, when the cover body with the reverse cover problem is superimposed on another correctly placed cover body, the common thickness of the two is significantly different from the thickness of the two covers arranged in the same direction. Therefore, the proximity sensor can be used to detect and determine whether the first cover body or the last cover body in the paper bag of the group of covers 7 has the reverse cover problem.

[0038] Due to the high speed of easy-open lid production, the front lid is easy to be turned upside down during the packaging process. If it cannot be detected, when the lid arrives at the filling plant, when the lid and the can body are screwed together, the screwing failure will occur due to the reversed lid, affecting the efficiency of the entire canning line. Manual sampling is not only inefficient, but also increases the labor intensity of workers.

[0039] Therefore, a cover body detection device provided by the utility model can detect and identify the ends of the grouped covers 7 by setting a constraint mechanism and a detection mechanism 2. When it is detected that the cover bodies in the group have a cover-inverted problem, it can be identified in time, and the cover bodies with the cover-inverted problem can be picked up and stored elsewhere by a robot or other transportation methods, which is not only conducive to the subsequent orderly stacking, but also conducive to the subsequent screwing of the cover body and the can body.

[0040] Further, in another preferred embodiment of the present application, the first limiting mechanism can move toward or away from the side where the second driving mechanism is located under the drive of a driving mechanism; the second limiting mechanism can move toward or away from the side where the first driving mechanism is located under the drive of a driving mechanism. That is to say, the first limiting mechanism and the second limiting mechanism can move relative to and opposite to each other. When the two move relative to each other, the first limiting mechanism and the second limiting mechanism can abut against the two ends of the grouped cover body 7 and squeeze and constrain the grouped cover body 7 so that the grouped cover body 7 forms a relatively tight arrangement, which is convenient for the detection of the detection mechanism 2. Of course, the first limiting mechanism and the second limiting mechanism can be connected to the cylinder drive. Taking the first limiting mechanism as an example, when the cylinder is extended or retracted, the first limiting mechanism can move toward the second limiting mechanism or move away from the second limiting mechanism. Of course, other driving methods can make the first limiting mechanism or the second limiting mechanism reciprocate, which are all within the protection scope of the present application.

[0041] More specifically, the first limiting mechanism includes a constraint base 11 and a constraint side seat 12, wherein the constraint side seat 12 is arranged on the constraint base 11, and the constraint side seat 12 and the constraint base 11 enclose a sub-constraint space, and the sub-constraint space is at least used to constrain the end of the grouped cover body 7. In a preferred embodiment, the first limiting mechanism includes at least two relatively arranged constraint side seats 12, and the two constraint side seats 12 and the constraint base 11 enclose the sub-constraint space. The grouped cover body 7 can be understood as a regular columnar object, that is, when constraining the grouped cover body 7, effectively restricting and restraining the end of the grouped cover body 7 can effectively constrain the grouped cover body 7 in the constraint space.

[0042] More specifically, Figure 2 As shown, the two constraint side seats 12 are arranged in sequence along the second direction, and the second direction is the horizontal direction. That is to say, the sub-constraint space enclosed by the two constraint side seats 12 and the constraint base 11 has an entrance for the grouped cover body 7 to enter in the vertical direction. Regardless of whether the grouped cover body 7 is dropped or placed in the constraint space, the first limiting mechanism can effectively constrain the end of the grouped cover body 7 to prevent the grouped cover body 7 from being dislocated.

[0043] More specifically, the constraint side seat 12 includes a constraint portion 121 and a guide portion 122, at least part of the guide portion 122 is arc-shaped, and the guide portions 122 of the two constraint side seats 12 are arranged opposite to each other, and the guide portions 122 of the two constraint side seats 12 form an opening for the end of the grouped cover body 7 to enter. The guide portion 122 can guide the grouped cover body 7 in a regular columnar shape, and the arc of the guide portion 122 can contact the outer wall surface of the grouped cover body 7, so that the grouped cover body 7 can slide or roll freely along the guide portion 122, so that it can fall into the constraint space more quickly and accurately.

[0044] In another preferred embodiment of the present application, the restraining mechanism also includes a first positioning member 13 and a second positioning member 14 that are relatively arranged, and the first positioning member 13 and the second positioning member 14 are respectively arranged on the first limiting mechanism and the second limiting mechanism, and the first positioning member 13 is matched with the positive end shape of the grouped cover body 7, and the second positioning member 14 is matched with the reverse end shape of the grouped cover body 7.

[0045] like Figure 3 one Figure 7 As shown, Figure 1 The enlarged schematic diagram of A in the middle is Figure 2 compared to, Figure 3 The first positioning member 13 and the second positioning member 14 can respectively fit with the positive end and the reverse end of the grouped cover body 7, and when the first limiting mechanism and the second limiting mechanism squeeze the grouped cover body 7, they can also play the effect of pressing the grouped cover body 7 together, making the grouped cover body 7 more compact.

[0046] Of course, the most important thing about the first positioning member 13 and the second positioning member 14 is that they can work together with the detection mechanism 2. If the opposite end of the grouped cover body 7 is placed on one side of the first limiting mechanism, the first positioning member 13 of the first limiting mechanism cannot be matched with the opposite end of the grouped cover body 7. Then, the detection mechanism 2 can more easily determine that the end of the grouped cover body 7 is not the positive end during detection and identification. Therefore, the first positioning member 13 and the second positioning member 14 are not only convenient for restraining and fixing the grouped cover body 7, but also enable the detection mechanism 2 to detect and identify the end of the grouped cover body 7 more accurately.

[0047] Furthermore, Figure 6The group of covers 7 shown is packed by stacking the covers in paper bags, and a first marker is set on the paper bag of the group of covers 7. During the stacking process, the first markers of the stacked group of covers 7 must be kept neat. Therefore, the cover detection device provided by the present application also includes an adjustment mechanism and an identification mechanism 4, the adjustment mechanism is arranged opposite to the constraint mechanism, the adjustment mechanism is at least used to carry the group of covers 7 and rotate the group of covers 7 in the constraint space, the identification mechanism 4 is used to identify the first marker of the group of covers 7, and when the identification mechanism 4 identifies the first marker, the group of covers 7 stops rotating.

[0048] When the cover is packed and sealed, there will be a certain degree of randomness in the sealing angle of the paper bag, and the bag mouth will be folded in half after sealing, and the height here will be higher than the other parts. Therefore, when the easy-open lid is stacked, if the bag mouth angle cannot be adjusted, the higher the number of stacking layers, the greater the accumulated height error at the bag mouth will be, which will cause the stacking to tilt and affect the stacking effect of the cover.

[0049] It is easy to understand that the first marker corresponds to the seal of the paper bag, which can be a black bar set along the axial direction of the grouped cover body 7. The adjustment mechanism can make the grouped cover body 7 rotate. When the identification mechanism 4 identifies the first marker, the grouped cover body 7 stops rotating. At this time, the grouped cover body 7 has not only completed the front and back end detection, but also has rotated to the specified angle. The first limiting mechanism and the second limiting mechanism can move in opposite directions to release the grouped cover body 7. Subsequently, the grouped cover body 7 can be transported and stacked by a manipulator or other equipment. The grouped covers formed by stacking are stacked tightly, and the seals of the grouped covers are stacked in an orderly manner to avoid the occurrence of stacking tilt or collapse problems.

[0050] Of course, the first marker in the present application may also have other colors, shapes or arrangements.

[0051] Specifically, the adjustment mechanism includes at least two roller components 31, and the two roller components 31 can rotate in the same direction under the drive of an external force. A certain gap can be left between the two rolling components, and the grouped cover body 7 can be placed between the two rolling components. When the roller components 31 rotate in the same direction, the grouped cover body 7 also rotates synchronously and in the same direction. The two roller components 31 can be connected to a motor drive, and of course can also be connected through a chain or belt drive. The chain or belt can move under the drive of the motor to drive the roller components 31 to roll.

[0052] More specifically, in another preferred embodiment of the present application, a cover detection device further includes a movable base 5, on which the adjustment mechanism and the constraint mechanism are movably disposed and can synchronously reciprocate along a first direction. The movable base 5 may be movably provided with a plurality of adjustment mechanisms and constraint mechanisms, which are arranged in sequence along the first direction.

[0053] That is to say, the movable base 5 can reciprocate along the first direction and the opposite direction of the first direction under the drive of an external force. A receiving station and a releasing station are respectively arranged along the first direction. When the movable base 5 is in the receiving station, the first limiting mechanism and the second limiting mechanism wait to constrain the grouped cover body 7. This receiving station can be placed downstream of the easy-open cover transfer mechanism. When the easy-open cover transfer mechanism releases a grouped cover body 7 at the receiving station, the first limiting mechanism and the second limiting mechanism can move relative to each other to squeeze the cover body. The detection mechanism 2 detects the end of the grouped cover body 7, and the adjustment mechanism rotates the grouped cover body 7 so that its first marker rotates to an appropriate angle.

[0054] After the inspection process is completed or during the inspection process, the movable base 5 moves from the receiving station to the releasing station. After the above inspection process is completed, the first limiting mechanism and the second limiting mechanism move in opposite directions to release the grouped cover bodies 7, and the grouped cover bodies 7 can be transported or stacked by a manipulator or other transport methods. The cover body detection device provided by the present application can not only carry the cover bodies released by the upstream easy-open cover transport mechanism, but also detect and identify the grouped cover bodies 7 that have been packaged. If the grouped cover bodies 7 are found to have a reverse cover problem during this process, they can be transported to the waiting inspection area by a manipulator. If the grouped cover bodies 7 are normal, they can be transported to the stacking area for orderly stacking, thereby improving the consistency of the grouped cover bodies 7, improving the progress of the stacking work, and ensuring the order of stacking.

[0055] like Figure 4 As shown, a cover detection device further includes an auxiliary component 6, wherein the auxiliary component 6 is arranged on both sides of the constraint space and is at least used to constrain the group of covers 7 in the limit space, see Figure 4 It is easier to understand that the auxiliary component 6 actually further constrains the position of the grouped cover body 7 to prevent the grouped cover body 7 from falling off during the rotation process.

[0056] Furthermore, the auxiliary component 6 is movably arranged on the movable base 5, and the auxiliary component 6 can slide along the length direction of the roller component 31. The position of the auxiliary component 6 can be adjusted according to actual processing requirements. After adjusting to a suitable position, the auxiliary component 6 can be fixed to the movable base 5 using fasteners.

[0057] It should be understood that the above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the utility model.
