Description

[Technical field]

[0001] The invention relates to the technical field of cup yogurt production, in particular to a filling production line. [Background technology]

[0002] In the field of yogurt filling production technology, yogurt cups are conveyed in a step-by-step manner, and the conveying power comes from a swing mechanism based on a parallel four-bar linkage structure. As is known to all, the movable link in the parallel four-bar linkage structure can make a rotational motion in space while maintaining a horizontal spatial posture. The motion range of the movable link is projected on the horizontal plane to form a horizontal reciprocating linear motion, and on the vertical plane to form a vertical reciprocating linear motion, and the two motions are performed simultaneously. The movable link is provided with a mold for setting up the yogurt cup. When the movable link moves, the yogurt cup will form a reciprocating motion in the vertical direction while obtaining a horizontal displacement operation. From the outside, it moves in a parabola-like trajectory, which makes the yogurt cup reciprocate in the vertical direction during the step-by-step conveying process. This motion process is short and it is very easy to shake the cup body and make it deviate from the given position, which has a negative impact on the subsequent filling operation.

[0003] In addition, common yogurt cups are mainly packaged in plastic cups, especially plastic cups produced based on the technology of linked cups. In this packaging form, the cup body has only one cavity for accommodating materials, and the cavity is filled with yogurt. Single-form yogurt products show weak market demand in the competition of dairy products. After all, there is only one product provided to consumers in a single cup body. If the taste is only original, it is bound to be at a disadvantage in the market competition with other products that are filled with different flavors from the original. On a larger scale, even if other flavors can be provided, the same cup body only provides a single flavor of yogurt products, which still lacks selling points compared to other newer dairy products.

[0004] Therefore, the prior art has developed a plastic cup with two cavities. Yogurts of different flavors are installed in the two cavities according to demand, or one cavity is filled with yogurt and the other cavity is filled with granular biscuits or other foods, so as to enhance consumers' eating experience and improve the market competitiveness of the product. During the production process, after the two materials are filled into the two cavities respectively, the plastic cup is transported to the film sealing station, and the cover film is heat-sealed to seal the two cavities. However, during the transportation process, the two materials may cross the cups. In order to prevent the above phenomenon from occurring, it is necessary to fill one cavity first, and then cover the two cavities with the cover film, and heat-seal the cover film so that part of the cover film seals the filled cavity, and then manually peel off the other part of the cover film to open the other cavity for the next step of filling. However, the manual film peeling method not only results in additional labor costs, but also leads to reduced production efficiency and the phenomenon of missing film peeling, thereby greatly increasing the production cost;

[0005] Finally, the filling equipment for filling granular food in the prior art includes a quantitative feeding device and a straight hopper that can be raised and lowered. When the yogurt cup is transported to the filling station, the straight hopper descends, and the quantitative feeding device feeds a quantitative amount of material into the straight hopper. The material enters one of the cavities through the straight hopper, thereby completing the filling of one of the cavities. However, when the existing filling equipment fills one of the cavities, the material transportation distance is long, which results in a long filling time, thereby reducing the filling efficiency. [Summary of the invention]

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a filling production line, which can completely avoid the vertical movement of the yogurt cups during the translational transportation of the yogurt cups, thereby preventing the yogurt cups from leaving a given position and facilitating subsequent filling operations; it can also realize automatic film peeling, thereby avoiding the occurrence of missing film peeling and reducing manufacturing costs; it can also effectively shorten the conveying distance of materials during filling, thereby shortening the filling time and improving the filling efficiency.

[0033] Beneficial effects of the present invention:

[0034] 1. When the translation driving component drives the conveying component to reciprocate in the horizontal direction, the design of the vertical directional transmission component can make the conveying component slide in the conveying direction relative to the lifting driving component, so as to avoid the lifting driving component interfering with the translation of the conveying component. When the lifting driving component drives the conveying component to reciprocate in the vertical direction, the horizontal directional transmission component can make the conveying component move in the vertical direction relative to the translation driving component, thereby avoiding the translation driving component interfering with the lifting and lowering of the conveying component. It can be seen that the translational movement and the lifting and lowering movement of the conveying component in the present invention do not interfere with each other, that is, the movement of the conveying component in the vertical direction is completely avoided when the conveying component is translated, and the yogurt cup will not be lifted when the conveying component is driven to translate and transport the yogurt cup, thereby avoiding the yogurt cup from leaving the given position, which is convenient for subsequent filling operations.

[0035] When the yogurt cup is conveyed to the bottom of the film-uncovering mechanism by the stepping conveying device, the film-uncovering mechanism uncovers the cover film. When the film-uncovering mechanism of the present invention is working, the third driving unit drives the first rocker arm to swing, thereby driving the connecting rod to perform a rotary motion while maintaining a horizontal state, and the rotary motion of the connecting rod drives the third rocker arm to swing, and the swing of the third rocker arm drives the air pipe to rotate, thereby realizing the driving of the suction cup to swing, and at the same time, the swing of the first rocker arm will also drive the bracket to perform a rotary motion while maintaining a horizontal state, thereby driving the second rocker arm to swing. In this way, when the third driving unit drives the disk surface of the suction cup to swing to a downward direction, the suction cup absorbs the cover film, and then the third driving unit drives the suction cup to swing and the bracket to swing, so that the suction cup uncovers the cover film, and then the suction cup releases the cover film, and the cover film remains uncovered under the action of the limit rod, so as to facilitate the later material filling. Subsequently, the third driving unit drives the first rocker arm to swing in the opposite direction, so that the suction cup and the bracket swing in the opposite direction to make the disk surface of the suction cup in a downward position, and after the suction cup absorbs the cover film, the third driving unit drives the bracket to swing and the suction cup to swing, so as to perform the film-uncovering action. It can be seen that the film peeling mechanism of the present invention can realize automatic film peeling, avoid the occurrence of missed film peeling, and reduce the manufacturing cost; in addition, the design of the guide member in the film peeling mechanism can keep the cover film in an uncovered state when the stepping conveyor device conveys the yogurt cup toward the filling and discharging device, so as to facilitate the subsequent filling.

[0036] When the filling and discharging device of the present invention is working, after the baffle closes the discharging port of the main hopper, a quantitative amount of material is put into the main hopper through the quantitative feeding device for temporary storage. When the container reaches the filling station, the lifting component drives the carrier platform to descend to a specified position, and then the driving component drives the baffle to flip to open the discharging port. At this time, the quantitative material is filled into the container. After the filling is completed, the driving component drives the baffle to flip to close the discharging port, and the lifting component drives the carrier platform to rise and reset, so that the main hopper receives the material put by the quantitative feeding device. It can be seen that compared with the way of the material moving from the quantitative feeding device to the container in the prior art, in the present invention, by temporarily storing the quantitative material in the main hopper for waiting to be put, compared with the conveying distance from the quantitative feeding device to the container, the conveying distance from the discharging port to the container in this technical solution is much shorter. In contrast, it can effectively shorten the conveying distance between the material and the container during filling, thereby shortening the filling time and improving the filling efficiency. In addition, by the way of opening and closing the discharging port with the baffle, the structure is relatively simple and the processing cost is relatively low.

[0037] 2. The lifting driving component includes a first driving unit and a first rotating shaft. The vertical directional transmission component includes a support block and a slider. The bottom end of the support block is fixedly connected to the first rotating shaft, and the top end of the support block is rotatably connected to the slider through a pin shaft. The slider is slidably connected to the conveying component and can reciprocally slide along the conveying direction of the conveying component. The first driving unit drives the first rotating shaft to rotate so that the support block swings. The swing of the support block can change the vertical distance and the distance in the conveying direction between the top end of the support block and the first rotating shaft. The change in the vertical distance drives the conveying component to generate reciprocating movement in the vertical direction through the slider, and the change in the distance in the conveying direction can eliminate the influence through the sliding of the slider, thereby completely avoiding the translation of the conveying component and the translation driving component. And the horizontal directional transmission component can enable the conveying component to generate vertical movement relative to the translation driving component. Therefore, when the conveying component is lifted or lowered, the translation of the conveying component and the lifting of the translation driving component can be completely avoided.

[0038] 3. A rocker is fixed on the first rotating shaft. The first rotating shaft includes a main active first rotating shaft and at least two driven first rotating shafts. The rocker includes a main rocker fixed on the active first rotating shaft and a driven rocker fixed on the driven first rotating shaft. A first transmission rod is rotatably connected between the main rocker and the adjacent driven rocker and between two adjacent driven rockers. The first driving unit drives the active first rotating shaft to rotate so that the rocker swings, and the swing of the rocker drives the driven first rotating shaft to rotate. Designed in this way, it can drive the support blocks on the active first rotating shaft and the driven first rotating shafts to swing synchronously through one first driving unit, thereby reducing the number of first driving units used and simplifying the structure. In addition, designed in this way, it can also enable the designer to reasonably configure different numbers of driven first rotating shafts according to the different lengths of the conveying component, so as to ensure the smoothness of the lifting movement of the conveying component.

[0039] 4. A slide rail is installed at the bottom of the conveying component, and a chute that slidably cooperates with the slide rail is provided at the top of the slider. With such a design, the smoothness of the relative sliding between the slider and the second chute can be ensured.

[0040] 5. The translation driving component includes a rocker arm and a second driving unit for driving the rocker arm to swing. The horizontal orientation transmission assembly includes a connecting portion and a guiding portion that slidably cooperates with the connecting portion vertically. The connecting portion is fixed on the conveying component, and the guiding portion is fixed on the rocker arm. The swing of the rocker arm will be transmitted to the connecting portion through the guiding portion, causing the connecting portion to drive the conveying component to translate. Since the conveying component is slidably connected to the slider, the lifting driving component will not interfere with the translation of the conveying component. And the vertical sliding cooperation between the connecting portion and the guiding portion can prevent the conveying component from generating a lifting motion. Therefore, when the conveying component translates, the lifting motion of the conveying component and the translation of the lifting driving component can be completely avoided.

[0041] 6. The second driving unit includes a second motor and a second driving shaft. The rocker arm includes a driving rocker arm fixed on the second driving shaft, and the second motor is connected to the second driving shaft. It is applicable to a conveying component with a relatively short length.

[0042] 7. The second driving unit further includes a second driven shaft, and the rocker arm further includes a driven rocker arm fixed on the second driven shaft. A second transmission rod is rotatably connected between the driving rocker arm and the adjacent driven rocker arm and between two adjacent driven rocker arms. With such a design, the translation driving component can be applicable to a conveying component with a relatively long length, and only one second motor is required, with a simple structure.

[0043] 8. The connecting portion is provided with a guiding hole, and the guiding portion is a roller that reciprocally slides vertically along the guiding hole. With such a design, the smoothness of the sliding can be improved, and the occurrence of jamming phenomena that cause the conveying component to be unable to lift can be avoided.

[0044] 9. A guiding groove that slidably cooperates with the inner wall of the guiding hole is provided on the outer peripheral side of the roller. With such a design, the guiding effect and the smoothness of the sliding cooperation are improved.

[0045] 10. A notch with an opening facing downwards is provided on the support plate. The notch is located between the limiting rod and the air delivery pipe, and the inner side surface of the notch is tangent to the outer peripheral surface of the limiting rod. With such a design, when conveying the covering film, the design of the notch can enable the covering film to move smoothly to the outside of the support.

[0046] 11. The guiding member includes an upper guiding strip and a lower guiding strip arranged in parallel. The upper guiding strip and the lower guiding strip are bent towards the same side along the conveying direction and then extend straight. With such a design, the covering film can be gradually guided to be turned to a vertical state on the movement path of the covering film, and then the cavity can be completely opened and exposed.

[0047] 12. The active swing arm unit further includes a connecting block. One end of the connecting block is fixedly connected to the second rotating shaft, and the other end is connected to the support rod connected to the first swing arm. With such a design, the back-and-forth swinging movement of the support can be made more stable.

[0048] 13. The loading platform is provided with a through hole for the main hopper to penetrate, and the main hopper is fixedly arranged on the loading platform. With such a design, the shaking of the main hopper can be avoided, ensuring that the quantitative feeding device can accurately feed the materials into the main hopper.

[0049] 14. The main hopper includes a main body part and a mounting part. One end of the main body part extends into the mounting part and is movably connected to the mounting part. A limiting plate extending outward is provided on the periphery of the mounting part. The limiting plate is pressed on the loading platform and fixedly connected to the loading platform through bolts. In this solution, the main body part and the mounting part can be independently processed and formed, and the two form the main hopper through later assembly. Compared with the method of integrally processing and forming the main hopper, this solution can effectively reduce the processing difficulty and thus effectively reduce the processing cost.

[0050] 15. The driving component includes a second driving member, a second rotating shaft, a second connecting block and a second connecting rod. The second rotating shaft is rotatably installed on the guiding hopper. The baffle is fixedly connected to the part of the second rotating shaft located inside the guiding hopper. The second connecting block is fixedly connected to the part of the second rotating shaft located outside the guiding hopper. The second driving member includes a driving rod that can move vertically back and forth. Two ends of the second connecting rod are respectively rotatably connected to the driving rod and the second connecting block. By the vertical reciprocating movement of the driving rod, the second connecting rod can be driven to swing. By the swing of the second connecting rod, the second connecting block can be driven to swing. The swing of the second connecting block drives the second rotating shaft to rotate, thereby driving the baffle to flip to open or close the discharge port.

[0051] 16. The second rotating shaft includes a driving rotating shaft and a driven rotating shaft. The second connecting block is fixedly connected to the driving rotating shaft, and the baffle is fixedly connected to the driven rotating shaft. The driving rotating shaft and the driven rotating shaft are movably connected through a quick-release structure. With such a design, it is convenient to separately disassemble and clean the guiding hopper later.

[0052] 17. The quick-release structure includes a transmission groove and a transmission protrusion. One of the transmission groove and the transmission protrusion is provided at one end of the driving rotating shaft, and the other is provided at one end of the driven rotating shaft. With such a design, the structure is simple and the processing difficulty is relatively low.

[0053] 18. A slot is provided on the bottom surface of the loading platform, and a plug plate is provided on the guide hopper. The guide hopper is inserted into the slot through the plug plate to be movably connected with the loading platform. With such a design, the insertion direction of the guide hopper can be designed to be consistent with the insertion direction of the transmission protrusion and the power transmission groove. In this way, the driven rotating shaft and the driving rotating shaft can be disassembled while the guide hopper is disassembled, and the driven rotating shaft and the driving rotating shaft can be plugged and matched while the guide hopper is installed, thereby improving the disassembly and assembly speed of the filling and discharging device.

[0054] 19. The bottom of the guide hopper is also provided with a pressure plate arranged around the filling port. During filling, the pressure plate presses on the edge of the container mouth. With this design, the container and the guide hopper can be sealed by the pressure plate, thereby avoiding the overflow of materials during the filling process, ensuring the weight of the materials in the container, and thus improving the qualified rate of the product.

The flanging at the top of the yogurt cup, that is, the edge part of the cup mouth, is supported by the support plates 11, and the body of the yogurt cup is located in the conveying channel.

[0086] The filling production line in this embodiment includes a stepping conveying device 100, a film peeling mechanism 200 and a filling and discharging device 300 arranged on a frame 10, and the film peeling mechanism 200 and the filling and discharging device 300 are arranged one by one along the conveying direction of the stepping conveying device 100; wherein the stepping conveying device 100 includes a conveying component, a translation driving component, and a lifting driving component, wherein the conveying component includes a plurality of conveying plates 110 arranged at equal intervals and parallel to each other, and the two ends of the plurality of conveying plates 110 are fixedly connected by a connecting rod 112, and one of the conveying plates 110 is provided between two adjacent support plates 11, and a supporting part is provided on the conveying plate 110, and the supporting part includes a plurality of molds 114 distributed at equal intervals along the length direction of the conveying plate 110, and a limiting opening 111 is formed between two adjacent molds 114, and the cup body of the yogurt cup is located in the limiting opening 111, and the edge of the yogurt cup mouth is pressed on the mold 114, and the two adjacent molds 114 support the yogurt cup.

[0087] like ​ As shown, the lifting drive component includes a first driving unit and a first rotating shaft. The first driving unit includes a first motor 120 fixed to the frame 10. The first rotating shaft includes an active first rotating shaft 151 and at least two driven first rotating shafts 152. The active first rotating shaft 151 and the driven first rotating shaft 152 are spaced apart and parallel to each other along the length direction of the conveying channel. For example, the first rotating shaft includes an active first rotating shaft 151 and three driven first rotating shafts 152. One of the three driven first rotating shafts 152 is located on one side of the active first rotating shaft 151, and the other two are spaced apart and distributed on the other side of the active first rotating shaft 151. A rocker is fixedly connected to the first rotating shaft. The rocker includes an active rocker 153 fixed on an active first rotating shaft 151 and a slave rocker 154 fixed on a driven first rotating shaft 152. A first transmission rod 155 is rotatably connected between the active rocker 153 and an adjacent slave rocker 154 and between two adjacent slave rockers 154. The first motor 120 is fixedly connected to the active first rotating shaft 151 through a reducer or directly. The first motor 120 drives the active first rotating shaft 151 to rotate to drive the active rocker 153 to swing. The swing of the active rocker 153 drives the slave rocker 154 to swing through the first transmission rod 155. The swing of the slave rocker 154 drives the driven first rotating shaft 152 fixedly connected thereto to rotate.

[0088] A vertical directional transmission assembly is provided between the active first rotating shaft 151 and the conveying plate 110, and between the driven first rotating shaft 152 and the conveying plate 110. The vertical directional transmission assembly includes a slider 130 and a support block 140. The above-mentioned support blocks 140 are respectively fixed on the active first rotating shaft 151 and the driven first rotating shaft 152. The top of the support block 140 is rotatably connected to the slider 130 through a pin shaft. A chute is provided at the top of the slider 130. A slide rail 113 parallel to the conveying plate 110 is provided at the bottom of at least one conveying plate 110. The chute is slidably connected to the slide rail 113 and can reciprocate along the length direction of the slide rail 113. The rotation of the active first rotating shaft 151 and the driven first rotating shaft 152 can drive the support block 140 to swing synchronously. The swing of the support block 140 will drive the slider 130 to reciprocate in the vertical direction and slide reciprocally along the slide rail 113. The reciprocating movement of the slider 130 in the vertical direction drives the conveying component to reciprocate in the vertical direction of the conveying channel.

[0089] The translation driving component includes a second driving unit and a rocker arm. The second driving unit drives the rocker arm to swing back and forth. The second driving unit includes a second motor 181, a second active rotating shaft 182 and a second driven rotating shaft 183. The second driven rotating shaft 183 is rotatably connected to a support 184. The second motor 181 and the support 184 are fixed on the frame 10. The rocker arm includes an active rocker arm 185 fixed on the second active rotating shaft 182 and a driven rocker arm 186 fixed on the second driven rotating shaft 183. A second transmission rod 187 is rotatably connected between the active rocker arm 185 and the driven rocker arm 186. The second motor 181 is fixedly connected to the second active rotating shaft 182 through a speed reducer or directly. The second motor 181 drives the second active rotating shaft 182 to rotate so that the active rocker arm 185 on the second active rotating shaft 182 swings. The swing of the active rocker arm 185 drives the driven rocker arm 186 to swing through the second transmission rod 187.

[0090] A horizontal directional transmission assembly is provided between the active swing arm 185 and the conveying component, and between the driven swing arm 186 and the conveying component. The horizontal directional transmission assembly includes a connecting portion 160 and a guiding portion 170 that is vertically slidably engaged with the connecting portion 160. The connecting portion 160 is a vertical connecting plate provided on the conveying component. A vertically extending guiding hole 161 is provided on the vertical connecting plate. The guiding portion 170 is provided on the active swing arm 185 and the driven swing arm 186. The guiding portion 170 is a roller, and a guiding groove that is slidably engaged with the inner wall of the guiding hole 161 of the vertical connecting plate is provided on the outer peripheral side of the roller. In this embodiment, the synchronous swinging of the active swing arm 185 and the driven swing arm 186 drives the roller to reciprocate horizontally while also sliding vertically along the guiding hole 161. The horizontal reciprocating movement of the roller drives the vertical connecting plate to drive the conveying component to reciprocate horizontally in the conveying channel. The sliding of the roller will prevent the conveying component from moving in the vertical direction. Thus, the conveying component can only perform reciprocating movement in the horizontal direction.

[0091] In the attached drawings of this embodiment, the direction of the next working station of the step conveyor device 100 is the front, and the direction of the previous working station of the step conveyor device 100 is the back. The translation driving component and the lifting driving component in this embodiment drive the conveying component to move in an asynchronous manner. Specifically, when the yogurt cup is moved towards the next working station direction by the conveying component, the conveying component is at a high position, and the first motor 120 stops working. At this time, the support block 140 is perpendicular to the horizontal line (as ​ shown), the edge of the mouth of the yogurt cup presses on the mold 114 and separates from the support plate 11. The second motor 181 drives the second driving shaft 182 to rotate forward so that the active swing arm 185 on the second driving shaft 182 swings forward. The swing of the active swing arm 185 drives the driven swing arm 186 to swing forward through the second transmission rod 187. The synchronous swing of the active swing arm 185 and the driven swing arm 186 drives the roller to swing forward. The forward swing of the roller is split into a forward movement in the horizontal direction and a vertical slide along the guiding hole 161. The sliding of the roller will prevent the conveying component from moving in the vertical direction. The forward movement of the roller drives the vertical connecting plate to drive the conveying component to move forward horizontally in the conveying channel. Since the slide rail 113 on the conveying component is slidably connected to the slider 130, the translation of the conveying component will not be interfered by the vertical directional transmission assembly, thereby avoiding driving the translation of the lifting driving component.

[0092] After the yogurt cup is conveyed to the next working station, the second motor 181 stops working, and the first motor 120 drives the active first rotating shaft 151 to drive the active rocker 153 to swing forward. The swing of the active rocker 153 drives the driven rocker 154 to swing forward through the first transmission rod 155. The swing of the driven rocker 154 drives the driven first rotating shaft 152 fixedly connected thereto to rotate. The synchronous rotation of the active first rotating shaft 151 and the driven first rotating shaft 152 drives all the supporting blocks 140 to swing forward synchronously so that the conveying component descends to a low position (such as ​ shown). During the forward swing of the supporting block 140, it will drive the slider 130 to move downward and at the same time drive the slider 130 to slide forward along the slide rail 113. The downward movement of the slider 130 will drive the conveying component to descend to a low position. The downward movement of the conveying component causes the guide hole 161 to move downward along the roller, thereby avoiding interference from the horizontal directional transmission component and preventing the translation drive component from descending. And the forward sliding of the slider 130 along the slide rail 113 will completely prevent the conveying component from moving in the horizontal direction. After the conveying component descends to a low position, the body of the yogurt cup disengages from the limiting port 111, and the edge of the cup mouth of the yogurt cup presses on the support plate 11, waiting to be received by the conveying component at the next working station.

[0093] After the conveying component descends to a low position, the first motor 120 stops working, and the second motor 181 drives the second active rotating shaft 182 to rotate backward so that the active rocker arm 185 on the second active rotating shaft 182 swings backward. The swing of the active rocker arm 185 drives the driven rocker arm 186 to swing backward through the second transmission rod 187. The synchronous swing of the active rocker arm 185 and the driven rocker arm 186 drives the roller to swing backward. The backward swing of the roller is split into a backward movement in the horizontal direction and a vertical slide along the guide hole 161. The sliding of the roller will prevent the conveying component from moving in the vertical direction. The backward movement of the roller will drive the vertical connecting plate to drive the conveying component to move backward in the horizontal direction of the conveying channel. And since the slide rail 113 on the conveying component is slidably connected to the slider 130, the translation of the conveying component will not be interfered by the vertical directional transmission component, thereby preventing the lifting drive component from translating.

[0094] After the conveying component moves backward in place, the second motor 181 stops working, and the first motor 120 drives the active first rotating shaft 151 to drive the active rocker 153 to swing backward. The swing of the active rocker 153 drives the driven rocker 154 to swing backward through the first transmission rod 155. The swing of the driven rocker 154 drives the driven first rotating shaft 152 fixedly connected thereto to rotate. The synchronous rotation of the active first rotating shaft 151 and the driven first rotating shaft 152 drives all the supporting blocks 140 to swing backward synchronously. When the supporting block 140 is perpendicular to the horizontal line (such as ​As shown in the figure, the conveying component rises to a high position. When the support block 140 swings backward, it drives the slider 130 to rise and slide backward along the slide rail 113. The rise of the slider 130 drives the conveying component to rise to a high position. The rise of the conveying component causes the guide hole 161 to move upward along the roller, thereby avoiding interference from the horizontal directional transmission component to avoid driving the translation drive component to rise. The slider 130 slides backward along the slide rail 113 to completely avoid the horizontal movement of the conveying component. After the conveying component rises to a high position, the cup body of the yogurt cup on the previous station is inserted into the limit opening 111, and the edge of the yogurt cup mouth is pressed on the mold 114, and then the above operation steps are performed again, thereby realizing the step-by-step conveying of the yogurt cup.

[0095] It can be seen that in this embodiment, the translational movement and the lifting movement of the conveying component do not interfere with each other, that is, when the conveying component is driven to translate, the vertical movement of the conveying component is completely avoided. Therefore, when the conveying component is driven to translate to convey the yogurt cup, the yogurt cup will not be lifted, thereby avoiding the yogurt cup from leaving the given position, which is convenient for subsequent filling operations.

[0096] After the stepping conveying device 100 is used to transport the yogurt cup to the bottom of the film peeling mechanism 200, the film peeling mechanism 200 peels off the cover film, that is, during production, ​ As shown, a portion of the cover film is first heat-sealed and fixed on the yogurt cup to seal the first cavity 01, and the other portion of the cover film is covered on the second cavity 02. The film peeling mechanism 200 is used to peel off the cover film 03 to open the second cavity 02, thereby facilitating the later filling of the second cavity 02 with materials.

[0097] like ​As shown, the film peeling mechanism 200 in this embodiment includes a film peeling assembly and a film cover guide assembly, the film peeling assembly includes a bracket 210, an active swing arm unit, a driven swing arm unit, a posture adjustment swing unit and a third driving unit, the bracket 210 is located above the support plate 11, the bracket 210 includes two parallel bracket plates 211 and a bracket rod 212 connected between the two ends of the two bracket plates 211, the bracket plate 211 is provided with a mounting hole, and a bearing is provided between the bracket rod 212 and the mounting hole, so that the bracket rod 212 rotates relative to the bracket plate 211. The active swing arm unit includes a first rocker arm 243 and a connecting block 245, the driven swing arm unit includes two second rockers 246, the posture adjustment swing unit includes an air pipe 220, a suction cup 230, a third rocker arm 244 and a connecting rod 242, the air pipe 220 is rotatably connected between the two bracket plates 211, the air pipe 220 is parallel to the bracket rod 212, and the suction cups 230 are spaced on the air pipe 220 at equal intervals. The third driving unit includes a third motor 240 and a second rotating shaft 241 connected to the third motor 240. The third motor 240 is fixed to the frame 10. The second rotating shaft 241 is horizontally arranged and parallel to the support plate 11. The bottom end of the first rocker arm 243 and the bottom end of the connecting block 245 are respectively fixedly connected to the second rotating shaft 241. The top end of the first rocker arm 243 is rotatably connected to one end of the connecting rod 242. The top end of the connecting block 245 is fixedly connected to one of the support rods 212, and one end of the support rod 212 is fixedly connected to the portion between the bottom and top ends of the first rocker arm 243. One end of the gas pipe 220 extends out of the outside of the support 210 and is connected to the third rocker arm 244. The bottom end of the second rocker arm 246 is fixedly connected, the top end of the third rocker arm 244 is rotatably connected to the connecting rod 242 through a pin shaft, the top end of the second rocker arm 246 is fixedly connected to another bracket rod 212, and the bottom end of the second rocker arm 246 is rotatably connected to the support plate 11, that is, the support plate 11 is provided with a support seat 14 which is relatively fixed to the support plate 11, and the support seat 14 is provided with a third rotating shaft 15, and the bottom end of the second rocker arm 246 is fixedly connected to the third rotating shaft 15, so that the second rocker arm 246 can realize a swinging motion; or the support plate 11 is provided with a hinge seat, and the bottom end of the second rocker arm 246 is rotatably connected to the hinge seat through a pin shaft, so that the second rocker arm 246 can also realize a swinging motion.

[0098] When the film peeling mechanism 200 is working, the third motor 240 drives the second rotating shaft 241 to rotate to drive the first rocker arm 243 and the connecting block 245 to swing. The swing of the first rocker arm 243 will simultaneously drive the connecting rod 242 and the bracket 210 to swing back and forth. The movement range of the bracket 210 is perpendicular to the horizontal direction. The movement of the connecting rod 242 will drive the third rocker arm 244 to swing. The swing of the third rocker arm 244 will drive the air pipe 220 to rotate. The rotation of the air pipe 220 will drive the suction cup 230 to swing. At the same time, the back and forth swinging of the bracket 210 will also drive the suction cup 230 to swing through the air pipe 220. The movement range of the suction cup 230 is located above the material support assembly.

[0099] In addition, a limiting rod 250 parallel to the gas pipe 220 is connected between the two support plates 211 in this embodiment. The limiting rod 250 corresponds to the gas pipe 220 one by one. The limiting rod 250 is located on one side of the gas pipe 220. In the working state of this embodiment, the limiting rod 250 can be located above the second cavity 02. The height of the limiting rod 250 in the vertical direction is greater than the lowest height of the plate surface of the suction cup 230 in the vertical direction. A notch 213 with an opening facing downward is also provided on the support plate 211. The notch 213 is located between the limiting rod 250 and the gas pipe 220. The inner side surface of the notch 213 is tangent to the outer peripheral surface of the limiting rod 250. In this way, when the plastic cup is transported, the cover film 03 can move to the outside of the support under the guidance of the limiting rod 250 and the notch 211.

[0100] The cover film guide assembly in this embodiment includes a guide member 260 arranged outside the bracket 210 and extending along the length direction of the support plate 11, so as to keep the cover film in an uncovered state during the process of conveying the yogurt cup to the bottom of the filling and discharging device, so as to facilitate the filling of the filling and discharging device. The guide member 260 is connected with the limit rod 250, so that when the yogurt cup moves to the outside of the bracket and continues to be conveyed, the cover film 03 can always be placed on the guide member 260 to keep the cover film 03 in an uncovered state, wherein the guide member 260 includes an upper guide bar 261 and a lower guide bar 262 arranged in parallel, and the upper guide bar 261 and the lower guide bar 262 are bent to the same side along the conveying direction and then extend straightly. In this embodiment, the upper guide bar 261 and the lower guide bar 262 are bent to the right side at the same angle along the conveying direction and then extend straightly, so that the cover film 03 can be gradually guided to flip to a vertical state on the movement path of the cover film 03, thereby making the second cavity 02 fully open and exposed.

[0101] In order to describe this embodiment more clearly, in this embodiment, after the yogurt cup is placed on the stepping conveyor 100, the second cavity 02 is located on one side of the first cavity 01 as the left side, and the first cavity 01 is located on one side of the second cavity 02 as the right side. ​As shown, in this embodiment, the disk surface of the suction cup 230 is parallel to the horizontal plane and is arranged downward. At this time, the disk surface of the suction cup is at the lowest height in the vertical direction. The suction cup 230, the first swing arm 243, the second swing arm 246, the third swing arm 243 and the bracket 210 are all in the first position. The air delivery pipe 220 is connected to a negative pressure generator, and the negative pressure generator sucks air to enable the suction cup 230 to adsorb the cover film 03. Subsequently, the third motor 240 drives the second rotating shaft 241 to rotate to drive the first swing arm 243 to swing 90° to the right. The swing of the first swing arm 243 will simultaneously drive the connecting rod 242 and the bracket 210 to perform swing movements. The second swing arm 246 swings under the drive of the bracket 210. The movement of the connecting rod 242 will drive the third swing arm 244 to swing 90° to the right. The swing of the third swing arm 244 will drive the air delivery pipe 220 to rotate 90°, so that the disk surface of the suction cup 230 swings to a state parallel to the vertical plane. In addition, the swing movement of the bracket 210 will also move the suction cup 230 to the right by a certain distance. During this process, while the suction cup 230 undergoes a spatial position movement, its spatial attitude also changes through self-rotation. Thus, the suction cup 230 can uncover the cover film 03. At this time, the suction cup 230, the first swing arm 243, the second swing arm 246, the third swing arm 243 and the bracket 210 are all in the second position (as ​ shown).

[0102] It should be noted that during the process of the suction cup 230 moving from the first position to the second position, since the cover film 03 is flexible, the cover film 03 will move upward over the limit rod 250. In this way, when the suction cup 230 is in the second position, after the negative pressure generator ventilates to enable the suction cup 230 to release the cover film 03, the cover film 03 will be placed on the limit rod 250 to keep the cover film 03 in an uncovered state. In the state where the cover-uncovering assembly is in the second position, the connection between the limit rod 250 and the upper guide bar 261 is that the end of the limit rod 250 faces the end of the upper guide bar 261. When the yogurt cup is conveyed by the conveying component to the next station for filling, during the conveyance to the next station, the cover film 03 passes through the notch 213 under the guidance of the limit rod 250 and is then placed on the guiding member 260. The guiding member 260 keeps the cover film 03 in an uncovered state during the conveyance. After the suction cup 230 releases the cover film 03, the third motor 240 drives the second rotating shaft 241 to rotate to drive the first swing arm 243 to swing 90° to the left, so that the suction cup 230, the first swing arm 243, the second swing arm 246, the third swing arm 243 and the bracket 210 move to the first position, so as to uncover the cover film 03 on the yogurt cup conveyed from the previous station, thereby realizing continuous film uncovering. It can be seen that by adopting the film-uncovering mechanism 200 of this embodiment, automatic film uncovering can be realized, avoiding the occurrence of missed film uncovering and reducing the manufacturing cost.

[0103] After using the stepping conveying device 100 to convey the yogurt cup to the lower part of the filling port of the filling and discharging device, the filling and discharging device 300 fills the second cavity 02 with materials.

During operation, the first driving member 331 drives the fourth rotating shaft 332 to rotate. The rotation of the fourth rotating shaft 332 drives the first connecting block 333 to swing. The swing of the first connecting block 333 drives the first connecting rod 334 to swing. Furthermore, the swing of the first connecting rod 334 drives the loading platform 320 to achieve lifting movement.

The bottom end of the main body part 341 extends into the installation part 342 to achieve the movable connection between the main body part 341 and the installation part 342. A through hole for the installation part 342 to penetrate is provided on the loading platform 320. A limiting plate 3421 that extends outward is provided on the peripheral side of the installation part 342. The limiting plate 3421 is press-fitted on the loading platform 320 and is fixedly connected to the loading platform 320 through bolts. Thus, the main hopper 340 is fixedly arranged on the loading platform 320.

[0105] ​The guiding hopper 350 and the driving component 360 are both installed on the loading platform 320. The bottom end of the guiding hopper 350 is provided with a filling port and a pressing plate 351 arranged around the filling port. The filling port is located directly above the conveying channel. The guiding member 260 extends along the conveying direction of the plastic cup to the lower part of the filling port. During filling, after the container (yogurt cup) is transported by the step conveying device to directly below the filling port, the pressing plate 351 presses on the edge of the mouth of the container. Among them, the guiding hopper 350 is located below the loading platform 320 and is sleeved on the outside of the installation part 342. The lower end of the installation part 342 is open to form a discharge port, and the discharge port is located inside the guiding hopper 350. The discharge port communicates the internal space of the main hopper and the internal space of the guiding hopper. A rotatable baffle 352 is arranged inside the guiding hopper 350. The driving component 360 drives the baffle 352 to rotate to open or close the discharge port, thereby controlling the on-off of the internal space of the main hopper and the internal space of the guiding hopper. The driving component 360 includes a second driving member 361, a fifth rotating shaft 362, a second connecting block 363 and a second connecting rod 364. The second driving member 361 is a cylinder, and the cylinder includes a cylinder body and a piston rod 3611 that vertically expands and contracts relative to the cylinder body. The piston rod 3611 forms a driving rod that can move vertically back and forth. The fifth rotating shaft 362 includes a driving rotating shaft 3621 and a driven rotating shaft 3622. The driving rotating shaft 3621 and the driven rotating shaft 3622 are movably connected through a quick-release structure. The driven rotating shaft 3622 is rotatably installed on the guiding hopper 350. The baffle 352 is fixedly connected to the driven rotating shaft 3622 through screws. The second connecting block 363 is fixedly connected to the driving rotating shaft 3621. The two ends of the second connecting rod 364 are respectively rotatably connected to the driving rod and the second connecting block 363. During operation, the cylinder drives the piston rod 3611 to move vertically back and forth. The vertical movement of the piston rod 3611 drives the second connecting rod 364 to swing. The swing of the second connecting rod 364 drives the second connecting block 363 to swing. The swing of the second connecting block 363 drives the fifth rotating shaft 362 to rotate, and then drives the baffle 352 to rotate to open or close the discharge port.

[0106] The quick-release structure in this embodiment includes a transmission groove and a transmission protrusion. The transmission protrusion is inserted and matched with the transmission groove. Both the transmission protrusion and the transmission groove are non-circular structures. For example, the transmission protrusion is a linear protrusion, and the transmission groove is a linearly extending through groove in the radial direction. One of the transmission groove and the transmission protrusion is provided at one end of the driving rotating shaft 3621, and the other is provided at one end of the driven rotating shaft 3622. A slot 321 is provided on the bottom surface of the load platform 320, and a plug board 353 is provided at the top of the guiding hopper 350. The guiding hopper 350 is movably connected to the load platform 320 by inserting the plug board 353 into the slot 321. Preferably, the direction of inserting the plug board 353 into the slot 321 is designed to be the same as the inserting direction of the transmission protrusion and the transmission groove. In this way, when the guiding hopper 350 is disassembled, the disassembly of the driven rotating shaft 3622 and the driving rotating shaft 3621 can be achieved at the same time. At the same time, when the guiding hopper 350 is installed, the plug-in fit between the driven rotating shaft 3622 and the driving rotating shaft 3621 can be achieved, thereby improving the disassembly and assembly speed of the filling and discharging device 300.

[0107] When the filling and discharging device 300 in this embodiment is in the high position state, that is ​ As shown, the driving component 360 drives the baffle 352 to flip to close the discharge port. The quantitative feeding device feeds a quantitative amount of material into the main hopper 340 for temporary storage. After the container (yogurt cup) is conveyed to the filling station by the step conveyor device, as ​ As shown, after the lifting component 330 drives the load platform 320 to descend to the specified position, the pressing plate 351 is pressed on the flange at the edge of the mouth of the second cavity 02. The driving component 360 drives the baffle 352 to flip to open the discharge port. At this time, the quantitative material is filled into the container. After the filling is completed, the driving component 360 drives the baffle 352 to flip to close the discharge port, and the lifting component 330 drives the load platform 320 to rise and reset, so that the main hopper 340 receives the material fed by the quantitative feeding device. It can be seen that compared with the way of the material moving from the quantitative feeding device to the second cavity in the prior art, in this embodiment, by temporarily storing the quantitative material in the main hopper 340 for storage and waiting for feeding, compared with the conveying distance from the quantitative feeding device to the second cavity, the conveying distance from the discharge port to the second cavity 02 in this technical solution is much shorter. In contrast, the conveying distance between the material and the container during filling can be effectively shortened, thereby shortening the filling time and improving the filling efficiency. In addition, by using the baffle 352 to open and close the discharge port, the structure is relatively simple and the processing cost is low.
