Description

Technical Field

[0001] The utility model particularly relates to a pull-tab lid feeding device and a pull-tab lid transfer device, belonging to the technical field of mechanical equipment. Background Art

[0002] In the existing pull-tab lid balancer feeding mechanism, the front pusher conveys the pull-tab lids stacked vertically into the balancer. To prevent the lids from tipping over, anti-tipping rubber sheets are added on both sides of the feeding area to squeeze the lids. After the lids are in place, the separating knife of the feeding mechanism cuts into the lids from directly above and then continues to push forward to separate the lids into groups, facilitating the subsequent transfer and storage of the grouped lids by the gripper mechanism of the robot (or three-axis electric cylinder).

[0003] The existing anti-tipping rubber sheets on both sides of the feeding mechanism are not only difficult to adjust during installation, but also the rubber sheets will turn up due to friction with the lids after running for a period of time, resulting in uneven pressure on the lids. When the pressure of the rubber sheets on the lids is large, the separating knife is likely to cause squeezing and abrasion when cutting into the lids. When the pressure of the rubber sheets on the lids is small, the lids are likely to tip over when the separating knife cuts into and pushes the lids. In addition, the anti-tipping rubber sheets need to be replaced regularly due to their service life, and the disassembly, installation and replacement are relatively difficult, and they can no longer keep up with the front-end production capacity of the production line in actual use. Therefore, how to avoid squeezing, abrasion and tipping of the lids and how to improve the process production speed and production capacity are still technical problems urgently needed to be solved in the industry.

[0031] When the separating knife of the pull-tab lid feeding device provided by the embodiment of the present utility model cuts into the lids, the impact is smaller, because the separating knife is a thin metal sheet, the cutting edge is subjected to profiling treatment, the size of the cutting edge into the lids is shorter, and the impact on the lids during cutting is smaller to prevent them from tipping in the forward direction.

[0038] In view of the deficiencies in the prior art, the inventors of this case have proposed the technical solution of the present utility model through long-term research and a large number of practices. The following will further explain the technical solution, its implementation process, principles, etc. Unless otherwise specified, the functional mechanisms such as the driving mechanism, controller, sensing device, and air source used in the embodiments of the present utility model are all known in the art and can be obtained through commercial purchase.

[0039] A lid feeding device provided in an embodiment of the present utility model is arranged between a lid pusher and a balancer. The main function of this lid feeding device is to separate the stacked lid bodies transported by the upstream lid pusher to form lid body groups containing a predetermined number and having a predetermined length, which is convenient for subsequent robots (or three-axis electric cylinders) to transfer and store the separated lid body groups.

[0040] Please refer to Figure 1 and Figure 2 , a lid feeding device, including a lid feeding frame 100, a lid separating assembly 200, a lid separating propulsion assembly 300, a lid pushing propulsion assembly 400, a sensing assembly 500, a lid separating anti-tipping blowing assembly 600, and a lid pushing anti-tipping blowing assembly 700. The lid separating assembly 200, the lid separating propulsion assembly 300, the lid pushing propulsion assembly 400, the sensing assembly 500, the lid separating anti-tipping blowing assembly 600, and the lid pushing anti-tipping blowing assembly 700 are all assembled on the lid feeding frame 100;

[0041] The lid feeding frame 100 is provided with a lid feeding channel 110 through which a plurality of stackable lid bodies 900 can continuously pass in a specified posture. The lid separating assembly 200 is used to separate the plurality of lid bodies 900 located in the lid feeding channel 110 into a plurality of mutually separated lid body groups. The lid separating propulsion assembly 300 and the lid pushing propulsion assembly 400 are used to push the lid body groups to travel along the lid feeding channel 110. The sensing assembly 500 is used to monitor the position of the foremost lid body 900 among the plurality of lid bodies 900 before separation. The lid separating anti-tipping blowing assembly 600 is used to output an air flow with a specified pressure to the end face of the exposed lid body 900 during the lid separating process of the lid separating assembly 200 to prevent the lid body 900 from tipping during the lid cutting process. The lid pushing anti-tipping blowing assembly 700 is used to prevent the lid body 900 from tipping during the process of the lid separating propulsion assembly 300 and the lid pushing propulsion assembly 400 pushing the lid body groups to travel.

[0042] Specifically, the cover inlet frame 100 may include a support frame and a cover inlet channel 110. The cover inlet channel 110, the sub-cover assembly 200, the sub-cover propulsion assembly 300, the cover propulsion assembly 400, the sensing assembly 500, the sub-cover anti-tipping air blowing assembly 600, and the cover anti-tipping air blowing assembly 700 are all assembled on the support frame. The support frame mainly provides structural support for the entire device, and its specific structure is not limited herein.

[0043] Specifically, the cover inlet frame includes multiple parallel and spaced support guide rods 111. The cover inlet channel 110 is formed between two adjacent support guide rods 111 to provide support and guidance for multiple covers 900 to pass through continuously. More specifically, the aforementioned designated posture refers to the posture in which the cover 900 stands upright, that is, the circumferential side surface of the cover 900 contacts the support guide rod 111. Therefore, the distance between two adjacent support guide rods 111 is less than the diameter of the cover 900. More specifically, the support guide rod 111 is made of metal. To avoid frictional damage to the area where the cover 900 contacts the support guide rod 111 during the traveling process, the area where the support guide rod 111 contacts the cover 900 is a smooth surface formed by polishing.

[0044] To prevent the cover 900 from tipping over during the cover cutting and traveling processes, the support guide rod 111 is inclined upward along the traveling direction of the cover 900, that is, lifted by a certain angle along the incoming cover direction, so that the cover 900 presents a backward-leaning posture in the cover inlet channel 110, thereby using its own weight to press the cover 900 in the incoming cover direction, so as to prevent the cover 900 from tipping forward during the cover cutting and traveling processes; of course, the inclination angle of the support guide rod 111 cannot be too large, as this will cause the cover 900 to tip backward. Preferably, the inclination / lifting angle of the support guide rod 111 is 3° - 45°.

[0045] Specifically, the cover inlet channel 110 includes a cover-separating area 101, a cover-separating advancing area 102, a cover-pushing area 103, a cover-pushing advancing area 105, a sensing area 104 and a cover-grabbing area 106, which are arranged in sequence from the inlet end to the outlet end. The cover-separating assembly 200 corresponds to the cover-separating area 101 and performs a cover-separating / cover-cutting action in the cover-separating area 101. The cover-separating advancing assembly 300 corresponds to the cover-separating area 101, the cover-separating advancing area 102 and the cover-pushing area 103. The cover-separating advancing assembly 300 can reciprocate between the cover-separating area 101, the cover-separating advancing area 102 and the cover-pushing area 103 to separate the cover body from the cover body. The sub-cover area 101 is pushed to the sub-cover area 103, the push-cover pushing assembly 400 corresponds to the push-cover area 103, the push-cover pushing area 105, and the grab-cover area 106, and the push-cover pushing assembly 400 can reciprocate between the push-cover area 103, the push-cover pushing area 105, and the grab-cover area 106 to push the cover body group from the push-cover area 103 to the grab-cover area 106, the sensing assembly 500 corresponds to the sensing area 104, the sub-cover anti-dumping blowing assembly 600 corresponds to the sub-cover area 101 and the sub-cover pushing area 102, and the push-cover anti-dumping blowing assembly 700 corresponds to the push-cover area 103 and the push-cover pushing area 105.

[0046] Specifically, the cover dividing assembly includes a first linear drive mechanism and a cover dividing knife 220, and the cover dividing knife 220 is transmission-connected to the first linear drive mechanism. The cover dividing knife 220 can move between the first workstation and the second workstation along a first direction under the drive of the first linear drive mechanism; when the cover dividing knife 220 is in the first workstation, there is no contact between the cover dividing knife 220 and the cover body 900, and when the cover dividing knife 220 is in the second workstation, the cover dividing knife 220 cuts into and is located between two adjacent cover bodies 900, wherein the first direction is parallel to the extension direction of the gap between adjacent cover bodies 900, and the first direction intersects with the moving direction of the cover body 900.

[0047] More specifically, the first linear drive mechanism may be a power mechanism capable of driving the capping knife 220 to realize linear reciprocating motion. For example, the first linear drive mechanism may be a linear drive cylinder, a linear drive electric cylinder, a linear drive motor or other power mechanisms.

[0048] For details, please refer to Figure 4 and Figure 5, to prevent the cover body 900 from tipping over during the cover cutting process, the whole of the cover separating knife 220 is a thin sheet structure. The cutting edge of the cover separating knife 220 is an arc structure similar to the side profile structure of the cover body 900, preferably a circular arc structure. The size of the cutting edge of the cover separating knife 220 changes according to the size of the cover body 900. The cutting edge of the cover separating knife 220 is polished. The material of the cover separating knife 220 can be metal or non-metal. Different from the conventional cover separating knife 220 that cuts into the center position of the cover body 900 (cuts in 30 mm), the cover separating knife 220 in the present utility model only needs to cut into the edge position of the cover body 900 (cuts in 3 mm). In this way, the extrusion amount caused when cutting into the cover body 900 is smaller, thereby preventing the cover body 900 from tipping over during the cover cutting and advancing process.

[0049] More specifically, please refer to Figure 4 and Figure 5 , the cover separating assembly further includes a pressing cover plate 210 and a base 230. The cover separating knife 220 is fixedly arranged on the pressing cover plate 210. The pressing cover plate 210 is fixedly arranged on the base 230. The base 230 is in transmission connection with the first linear driving mechanism. More specifically, the cover separating knife 220 is correspondingly arranged in the area between the two end parts of the pressing cover plate 210. More specifically, the pressing cover plate 210 includes a cover feeding pressing part 211 and a cover cutting pressing part 212. The cover separating knife 220 is located between the cover feeding pressing part 211 and the cover cutting pressing part 212. When the cover separating knife 220 performs the cover separating / cutting action, the cover feeding pressing part 211 of the pressing cover plate 210 presses on multiple cover bodies 900 in the upstream, and the cover cutting pressing part 212 presses on the separated cover body groups in the downstream, thereby further preventing the cover body 900 from tipping over during the cover cutting process.

[0050] Specifically, the cover separating and advancing assembly 300 can be integrally in transmission connection with the cover separating assembly, that is, the whole cover separating assembly can reciprocate between the positions corresponding to the cover separating area 101 and the cover pushing area 103 under the drive of the cover separating and advancing assembly 300. More specifically, the cover separating and advancing assembly 300 includes a second linear driving mechanism. More specifically, the second linear driving mechanism can be a power mechanism capable of driving the cover separating assembly to perform linear reciprocating motion. For example, the second linear driving mechanism can be a linear driving cylinder, a linear driving electric cylinder, a linear driving motor, and other power mechanisms, etc.

[0051] Specifically, the cover pushing and advancing assembly 400 includes a pushing block and a third linear driving mechanism. The third linear driving mechanism is in transmission cooperation with the pushing block and is used to drive the pushing block to reciprocate along the cover feeding channel 110.

[0052] Specifically, the whole cover separating assembly is correspondingly arranged above the cover feeding channel 110, and the whole cover pushing and advancing assembly 400 is correspondingly arranged below or on the side of the cover feeding channel 110.

[0053] The push block contacts the end face of the cover body group and pushes the cover body group to move along the cover entry channel 110 until the cover body group is pushed to the cover grabbing area 106 and resets. Specifically, when the push block is in the initial state, it can be tilted upward along the direction of travel of the cover assembly. It should be noted that the push block can also be connected to the slider via a torsion spring or the like to achieve a reset effect of the push block.

[0054] Specifically, the third linear drive mechanism is a power mechanism that can realize linear reciprocating drive. For example, the third linear drive mechanism can be a linear drive cylinder, a linear drive electric cylinder, a linear drive motor, or other power mechanisms.

[0055] Specifically, the sensing assembly 500 can be triggered by the cover body 900. The sensing assembly 500 is in communication with the sub-cover assembly 200. It should be noted that the sensing assembly 500 can be triggered by any triggering method, such as infrared triggering or visual triggering, and is not limited here. Of course, in addition to the direct connection between the sensing assembly 500 and the sub-cover assembly 200, the two can also be indirectly connected through a controller. Specifically, the controller receives and processes the trigger signal of the sensing assembly 500 and, in turn, adjusts the operating state and operating parameters of the sub-cover assembly 200. Of course, the controller and the CNC program contained therein are all known in the art and can be purchased commercially.

[0056] Specifically, the structures of the split cover anti-dumping blow assembly 600 and the push cover anti-dumping blow assembly 700 are the same, and the two are mainly different in their settings and areas of action. The split cover anti-dumping blow assembly 600 is used to output airflow to the cover body 900 located in the split cover area 101, and the push cover anti-dumping blow assembly 700 is used to output airflow to the cover body 900 located in the split cover advancement area 102, the push cover area 103 and the push cover advancement area 105. The structure of the split cover anti-dumping blow assembly 600 is introduced and explained below using the example of the split cover anti-dumping blow assembly 600, so that the structure of the push cover anti-dumping blow assembly 700 can be obtained without any objection. Please refer to Figure 1 、 Figure 3 andFigure 4 The sub - cover anti - tipping air - blowing assembly 600 includes an air source 800 and a blowing box 610. The blowing box 610 is correspondingly arranged on both sides of the cover - feeding channel 110. On the side of the blowing box 610 facing the cover - feeding channel 110, there are a plurality of air - blowing ports 611. The plurality of air - blowing ports 611 are arranged at intervals along the length direction of the cover - feeding channel 110. The blowing box 610 is connected to the air source, and the air - blowing ports 611 face the end face of the cover body 900 located in the cover - feeding channel 110. In order to better make the provided air flow prevent the cover body 900 from tipping, there are three rows of air - blowing ports on the blowing box. The multiple air - blowing ports included in each row are arranged in sequence along the length - extending direction of the cover - feeding channel. These three rows of air - blowing ports respectively face the upper region, the middle region, and the bottom region of the cover body located in the cover - feeding channel. It should be noted that the air source 800 can be a device that provides positive - pressure air flow. For example, the air source 800 can be a blower, etc.

[0057] Specifically, the cover body 900 is continuously conveyed into the cover - feeding channel 110 of the easy - pull - tab cover - feeding device by the upstream pusher. When the upstream pusher starts to convey the cover body 900, the air source 800 of the easy - pull - tab cover - feeding device communicates with the blowing box 610 and provides a continuous and stable positive - pressure air flow from the air - blowing ports 611 to the cover - feeding channel 110. When the cover body 900 travels in the cover - feeding channel 110, this continuous and stable air flow is output from the air - blowing ports 611 and acts on the cover body 900 in the horizontal direction to prevent it from tipping.

[0058] When the foremost cover body 900 reaches the sensing area 104, the sensing assembly 500 is triggered. The sensing assembly 500 sends a trigger signal to the controller. When the sub - cover assembly is in the initial position, it has no contact with the cover body 900. After receiving the trigger signal from the sensing assembly 500, the controller drives the sub - cover assembly 200 to act. The sub - cover knife 220 is driven by the first linear driving mechanism to cut into the space between two adjacent cover bodies 900. After the sub - cover knife 220 cuts in place, the sub - cover pushing assembly 300 drives the sub - cover assembly 200 and the group of cover bodies separated by the sub - cover assembly to continue moving forward. After the group of cover bodies is pushed to the cover - pushing area 103, the sub - cover pushing assembly 300 drives the sub - cover assembly 200 to reset (i.e., return to the cover - cutting area). The cover - pushing propulsion assembly 400 continues to push the group of cover bodies forward until the cover - grasping area 106. After the cover body 900 reaches the cover - grasping area 106, the robot transfers and stores the grouped cover bodies.

[0059] Of course, in addition to being applicable to easy - pull - tabs, the present utility model can of course also be applicable to other sheet - like products that need to be stacked and separated.

[0060] An easy-open lid feeding device provided by an embodiment of the present utility model outputs continuous and stable positive pressure air flows from both sides of the feeding channel. The air flows act horizontally on the center of the lid to prevent it from tipping in the forward direction. At the same time, by raising the feeding channel at a certain angle along the advancing direction, the lid is tilted towards the incoming lid direction, and its own weight is used to press the lid tightly to prevent the lid from tipping in its forward direction. In addition, when the lid separating knife of the present utility model cuts into the lids, the impact is smaller because the lid separating knife is a thin metal sheet, the incision is subjected to profiling treatment, the size of the incision into the lid is short, and the impact on the lid during cutting is small to prevent it from tipping in the forward direction.

[0061] It should be understood that the above embodiments are only for explaining the technical concept and features of the present utility model, and their purpose is to enable those skilled in the art to understand the content of the present utility model and implement it accordingly, and should not be used to limit the protection scope of the present utility model. Any equivalent changes or modifications made according to the spirit and essence of the present utility model should be covered within the protection scope of the present utility model.
