For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0026] Filling equipment is widely used in food, medicine, medical beauty, daily chemical sub-packaging and other fields, such as RTU (ready-to-use) vials, cartons, pre-filled bottles and other products in automatic filling production, to realize the weighing and filling function, and can also be used for other parallel containers on the nest plate.

[0027] The current filling equipment arranges a group of weighing stations, and transfers a group of empty containers before filling to the weighing station for pre-filling weighing by a mechanical hand. After weighing, the mechanical hand transfers the empty bottles to the filling station for filling, waits for the filling to be completed, and then transfers the filled bottles to the weighing station for post-filling weighing, and then performs the next container weighing and filling. This will cause the filling and weighing action to be discontinuous, the container transfer process to be complicated, and the production efficiency to be reduced.

[0028] In order to improve the production efficiency of the filling operation, some embodiments of the present application provide a filling device. The filling device designs a pre-filling weighing station and a post-filling weighing station, arranges the filling and weighing into a pipeline form. It is beneficial to the continuity of the container flow. At the same time, the container un-nesting and the container re-nesting are continuously carried out in the process of the nest plate flow, which is also beneficial to the continuity of the container flow. Thus, the production efficiency of the filling operation is improved.

[0029] The structure of the filling device provided by some embodiments of the present application will be described below. Figures 1 to 6 The structure of the filling device provided by some embodiments of the present application will be described below.

[0030] As shown in Figures 1 to 6 some embodiments of the present application provide a filling device including a first conveying mechanism 11, a second conveying mechanism 12, a first transfer mechanism 13, a first weighing mechanism 14, a filling mechanism 15, a second weighing mechanism 16, a capping mechanism 17 and a second transfer mechanism 18. The first conveying mechanism 11 is used to convey the nest plate 100 loaded with containers, and the first conveying mechanism 11 is sequentially provided with a transfer station 111 and a receiving station 112 along the conveying direction. The second conveying mechanism 12 is provided with a plurality of carriers 121, and the second conveying mechanism 12 is sequentially provided with a feeding station 122, a first weighing station 123, a filling station 124, a second weighing station 125, a capping station 126 and a discharging station 127 along the conveying direction. The first transfer mechanism 13 is used to transfer the containers loaded by the nest plate 100 located at the transfer station 111 to the carriers 121 located at the feeding station 122. The first weighing mechanism 14 is used to weigh the containers on the carriers 121 located at the first weighing station 123. The filling mechanism 15 is used to fill the containers on the carriers 121 located at the filling station 124. The second weighing mechanism 16 is used to weigh the containers on the carriers 121 located at the second weighing station 125. The capping mechanism 17 is used to cap the containers on the carriers 121 located at the capping station 126. The second transfer mechanism 18 is used to transfer the containers on the carriers 121 located at the discharging station 127 to the nest plate 100 located at the receiving station 112.

[0031] The first conveying mechanism 11 is used to convey the nest plate 100. The nest plate 100 loaded with the containers can be fed at the conveying starting point of the first conveying mechanism 11 and reach the transfer station 111 along with the operation of the first conveying mechanism 11. The transfer station 111 is located on the conveying path of the first conveying mechanism 11 and is a station for transferring the containers loaded on the nest plate 100. As the containers are transferred out of the nest plate 100, the nest plate 100 is gradually emptied. The emptied nest plate 100 will follow the operation of the first conveying mechanism 11 to reach the receiving station 112. The receiving station 112 is a station for receiving the containers after filling and stoppering. That is, the containers after filling and stoppering can be returned to the nest plate 100 to continue to circulate with the nest plate 100. The first conveying mechanism 11 can mainly consist of a servo drive, a conveying belt and a nest plate 100 positioning mold.

[0032] The second conveying mechanism 12 is used to drive the containers to circulate among different operation stations. The second conveying mechanism 12 has a container carrier 121. The containers transferred out of the nest plate 100 can be placed on the carrier 121 and then pass through different operation stations in sequence along with the operation of the second conveying mechanism 12. The second conveying mechanism 12 drives the carrier 121 to pass through the feeding station 122, the first weighing station 123, the filling station 124, the second weighing station 125, the stoppering station 126 and the discharging station 127 in sequence, respectively, to perform the feeding, pre-filling weighing, filling, post-filling weighing, stoppering and discharging operations of the containers. The carrier 121 can make corresponding shapes to carry and position the containers according to different specifications of the containers. The first conveying mechanism 11 can be arranged in a ring shape to circulate the carrier 121.

[0033] The first transfer mechanism 13 is used to transfer the containers by clamping. Corresponding to the transfer station of the first conveying mechanism 11, the first transfer mechanism 13 can clamp the containers on the nest plate 100 and transfer them to the carrier 121 located at the feeding station 122. The first transfer mechanism 13 can simultaneously transfer the containers located on the same straight line and transfer the large number of containers loaded on the nest plate 100 to different carriers 121 in batches through repeated actions. In this way, the containers can be subjected to different operation operations along with the operation of the second conveying mechanism 12. The first transfer mechanism 13 can mainly consist of a three-axis robot and a suction cup or a clamping jaw.

[0034] The first weighing mechanism 14 can weigh the containers on the carrier 121 at the first weighing station 123 to obtain the weight of the containers before filling. The first weighing mechanism 14 can cooperate with the weighing member 141 through the pushing member to achieve the weighing operation before filling. The first pushing member 142 can push the containers on the carrier 121 at the first weighing station 123 to the weighing member 141, and after the weighing member 141 detects the weight of different containers, the second pushing member 143 arranged oppositely pushes the containers back to the carrier 121 at the first weighing station 123. The weighing member 141 can be installed through the bracket.

[0035] The filling mechanism 15 can fill the containers on the carrier 121 at the filling station 124 with liquid such as medicine or beverage, so that the liquid enters the interior of the containers. In the vicinity of the second conveying mechanism 12, a liquid storage mechanism 151 for storing liquid bags or liquid tanks filled with liquid can be arranged. At the same time, the filling mechanism 15 can use a pump to pressurize and inject the liquid, and the pump assembly 152 can be arranged at a position adjacent to the second conveying mechanism 12. In actual cases, the filling mechanism 15 can also include a nitrogen filling assembly 153 for nitrogen filling operation, and the second conveying mechanism 12 can be provided with a corresponding nitrogen filling station 1211. The completion of filling can be achieved by cooperation of a servo drive, a lifting shaft, a lifting shaft support, a filling needle support and a filling needle, and a vacuum assembly can also be used to meet the requirements of vacuum filling products. The filling mechanism 15 can also fill the liquid while filling nitrogen.

[0036] The second weighing mechanism 16 can weigh the containers on the carrier 121 at the second weighing station 125 to obtain the weight of the containers after filling. The second weighing mechanism 16 can also cooperate with the weighing member through the pushing member to achieve the weighing operation after filling. The pushing member can push the containers on the carrier 121 at the second weighing station 125 to the weighing member, and after the weighing member detects the weight of different containers, the other pushing member arranged oppositely pushes the containers back to the carrier 121 at the second weighing station 125.

[0037] The capping mechanism 17 can cap the containers on the carrier 121 at the capping station 126 to seal the interior of the containers by installing the bottle stopper into the bottle mouth of the containers. The capping mechanism 17 can be matched with the height-adjustable material arranging member 20 to meet various capping modes, such as vacuum capping, mechanical capping, vacuum-assisted mechanical capping, and mechanical capping with nitrogen filling hole. The present case is illustrated as mechanical capping. In actual cases, adjusting the height of the material arranging member 20 can avoid adjusting the height of the capping mechanism, thereby avoiding the decrease of efficiency caused by the increase of capping stroke.

[0038] The second transfer mechanism 18 is used for clamping and transferring the containers. The second transfer mechanism 18 is arranged corresponding to the receiving station 112 of the first conveying mechanism 11, and can clamp the containers on the carrier 121 and transfer the containers to the nest plate 100 at the receiving station 112. The second transfer mechanism 18 can simultaneously transfer the containers in the same line, and can transfer a plurality of containers on different carriers 121 to the same nest plate 100 in batches through repeated actions, so that the containers can be returned to the corresponding nest plate 100. The second transfer mechanism 18 can mainly include a three-axis robot and a suction cup or a clamping jaw.

[0039] The filling device provided by some embodiments of the present application is provided with different conveying mechanisms to realize the circulation of the nest plate 100 and the containers. The conveying mechanism for driving the circulation of the containers can cooperate with the weighing mechanism, the filling mechanism 15 and the capping mechanism 17 to realize the weighing, filling and capping processes of the containers. The container de-nesting and re-nesting can be realized by different transfer mechanisms, so that the containers can be separated from the nest plate 100 for subsequent weighing, filling and other processes, and can be returned to the nest plate 100 after the completion of different processes. Thus, the circulation of the containers in the processes is realized, and the production efficiency of the filling process is improved.

[0040] In some embodiments, the filling device can further include a third conveying mechanism 101 and a third transfer mechanism 102. The third conveying mechanism 101 is used for conveying nest boxes, and the nest boxes are arranged with the nest plates 100 loaded with the containers. The third transfer mechanism 102 is arranged at the conveying starting point of the first conveying mechanism 11, and is used for transferring the nest plates 100 in the nest boxes on the third conveying mechanism 101 to the first conveying mechanism 11.

[0041] The third conveying mechanism 101 is used for conveying the nest boxes, and the nest boxes are used for placing the nest plates 100. The nest boxes can provide space for the processing of the nest plates 100 and the containers, and realize the centralized processing of a plurality of containers. By arranging the third conveying mechanism 101 adjacent to the first conveying mechanism 11, the conveying processes of the nest boxes and the nest plates 100 can be closely linked. This facilitates the transfer of the nest plates 100 from the nest boxes to the first conveying mechanism 11. The third conveying mechanism 101 can mainly include a servo drive and a conveying belt, and the conveying belt can carry a plurality of nest plates 100 to the positioning mold.

[0042] The transfer of the nest box can be achieved by a third transfer mechanism 102. The third transfer mechanism 102 can adopt the form of clamping or sucking to fix the nest box, and transfer the nest box together with the container loaded by the nest box to the first transmission mechanism 11. The driving part of the third transfer mechanism 102 can adopt the form of a mechanical hand to drive the movement of the nest plate 100 in space and keep the direction of the nest plate 100 unchanged. In actual cases, the third transfer mechanism 102 can be composed of a two-axis mechanical hand and a suction cup or a clamping jaw, and the double-servo-driven mechanical arm is lifted and rotated, and the mechanical arm can be equipped with a planetary wheel structure to keep the direction of the nest plate 100 unchanged during the rotation of the mechanical arm.

[0043] As shown in Figure 1 , the filling device can further include a fourth transfer mechanism 103 located at the transmission endpoint of the first transmission mechanism 11, and the fourth transfer mechanism 103 is used to transfer the nest plate 100 located at the transmission endpoint of the first transmission mechanism 11 into the nest box located on the third transmission mechanism 101.

[0044] By setting the fourth transfer mechanism 103 at the transmission endpoint of the third transmission mechanism 101, the nest plate 100 can be conveniently returned to the nest box. After the containers are subjected to different operations and returned to the nest plate 100, the first transmission mechanism 11 transmits the nest plate 100 to the transmission endpoint. The fourth transfer mechanism 103 located at the transmission endpoint of the first transmission mechanism 11 can transfer the nest plate 100 arriving at the transmission endpoint into the nest box located on the third transmission mechanism 101. Thus, the nest plate 100 is returned to the nest box. In actual cases, the fourth transfer mechanism 103 can be composed of a two-axis mechanical hand and a suction cup or a clamping jaw, and the double-servo-driven mechanical arm is lifted and rotated, and the mechanical arm can be equipped with a planetary wheel structure to keep the direction of the nest plate 100 unchanged during the rotation of the mechanical arm.

[0045] In some embodiments, the transmission direction of the third transmission mechanism 101 can be parallel to the transmission direction of the first transmission mechanism 11, and the nest box and the nest plate 100 can be transmitted synchronously.

[0046] As shown in Figure 1 , the third transmission mechanism 101 and the first transmission mechanism 11 are arranged in parallel, the third transmission mechanism 101 transmits the nest box on the side where the third transmission mechanism 101 is located, and the first transmission mechanism 11 transmits the nest plate 100 on the side where the first transmission mechanism 11 is located. Moreover, the third transmission mechanism 101 and the first transmission mechanism 11 transmit synchronously. In this way, the nest plate 100 separated from the nest box and transferred to the first transmission mechanism 11 can be returned to the corresponding nest box at the transmission endpoint of the first transmission mechanism 11, which facilitates the consistency of the nest box and the nest plate 100 during the circulation.

[0047] In some embodiments, the filling device can further comprise a first and a second reject mechanism 21 and 22, and the second conveying mechanism 12 is provided with a first and a second reject station 128 and 129 between the capping station 126 and the dispensing station 127, the first reject mechanism 21 is used to eject the container on the carrier 121 of the first reject station 128 from the carrier 121, and the second reject mechanism 22 is used to eject the container on the carrier 121 of the second reject station 129 from the carrier 121.

[0048] The reject mechanism can eject the containers that do not meet the filling requirements, such as unqualified weighing or capping, to prevent the containers that do not meet the filling requirements from continuing to flow forward. The reject mechanism can mainly consist of a linear module, a reject needle rack, and a reject collection mold. By providing the reject mechanism at different positions of the first conveying mechanism 11, the unqualified product rejection of multiple containers placed in close proximity can be adapted. Different reject mechanisms can be used for rejection of parts of closely arranged containers. For example, the reject needles in each reject mechanism can be arranged in a corresponding relationship with one stopper interval for rejection. Taking an arrangement of ten containers as an example, i.e., five containers are placed on each carrier 121, the first reject mechanism 21 can be used for targeted unqualified product rejection of the first, third, fifth, seventh, and ninth containers from one side, and the second reject mechanism 22 can be used for targeted unqualified product rejection of the second, fourth, sixth, eighth, and tenth containers.

[0049] As shown in Figure 4 The filling mechanism 15 can include a stopper pressing member 151 and a stopper feeding member 152, the stopper pressing member 151 is movable in a direction close to / away from the carrier 121 at the capping station 126 to drive the stopper into the bottle mouth of the container, and the stopper feeding member 152 is used to position the stopper. The stopper receiving member 191 is located on the movement path of the stopper pressing member 151 when the filling mechanism 15 performs the capping operation.

[0050] The stopper pressing member 151 can be driven by a servo to move, and the movement of the stopper pressing member 151 can stably drive the stopper to move to the bottle mouth of the container and finally complete the capping operation. During the movement of the stopper pressing member 151, the stopper can be adsorbed in the form of vacuum to ensure the control of the movement of the stopper. In actual cases, the capping mechanism 17 can be provided with a stopper guiding assembly, and the movement of the stopper can be guided by the stopper guiding cylinder 153 to smoothly transfer the stopper to the bottle mouth of the container. The stopper guiding cylinder 153 can be installed on the lifting shaft 155 through the stopper guiding cylinder mounting arm 154, and the lifting shaft 155 is movably installed in the lifting shaft support seat 156. At the same time, the stopper pressing member 151 can be installed through the stopper pressing member mounting arm 157, and the stopper pressing member mounting arm 157 is installed on the stopper pressing lifting shaft 158, and the stopper pressing lifting shaft 158 is movably installed in the lifting shaft 155.

[0051] In addition, the plug feeding member 152 can have a first state in which the plug feeding member 152 is located on the moving path of the plug pressing member 151 and a second state in which the plug feeding member 152 exits the moving path of the plug pressing member 151.

[0052] By controlling the conversion of the plug feeding member 152 between different states, the positioning of the bottle plug on the plug feeding member 152 can be facilitated, and after the positioning of the bottle plug is completed, the capping operation can be performed by changing the state of the plug feeding member 152. In actual cases, the plug feeding member 152 can be servo-driven, and can be installed by rotating shaft support seat 1521, rotating shaft 1522, and plug feeding arm. According to different working conditions, the position and discharge direction of the sorting member 20 can be adjusted, and the swing plug feeding can be changed to linear plug feeding.

[0053] In some embodiments, the filling device can further include a plug poking mechanism 19, which includes a plug receiving member 191 for accommodating the bottle plug and a movable plug poking member 192 for moving the bottle plug to the plug feeding member 152 when the plug feeding member 152 is in the second state.

[0054] The plug receiving member 191 of the plug poking mechanism 19 can accommodate the bottle plug, and the plug poking member 192 can move the bottle plug to the plug feeding member 152 during movement. Thus, the automatic transfer of the bottle plug is realized, and a large number of bottle plugs can be transferred simultaneously. The plug poking mechanism 19 can include a servo drive, a lifting shaft 193, a lifting shaft support seat 194, a plug poking needle mounting arm 195, and a plug poking needle. The plug receiving member 191 can be installed by a plug receiving arm and a plug receiving arm support column.

[0055] As shown in FIGS. Figure 1 and Figure 5 The filling device can further include a sorting member 20, which is provided with a plurality of sorting channels 21 spaced from each other, and the plug poking mechanism 19 is arranged adjacent to the sorting member 20, and the plug receiving member 191 is located at the end of the sorting channel 21.

[0056] The sorting member 20 can arrange the bottle plugs in a certain posture and distance, i.e., control different bottle plugs to move along different sorting channels 21 and finally reach different accommodation spaces on the plug receiving member 191. Through the action of the sorting member 20, the bottle plugs can be arranged, so that a plurality of bottle plugs are transferred to the plug receiving member 191 for subsequent batch capping operation. In addition, the sorting member 20 can adjust the discharge height of the rubber plug by lifting or replacing the mold to meet different capping modes.

[0057] In actual situations, when the first conveying mechanism 11 operates to make the carrier 121 reach the capping station 126, the plug receiving member 191 receives the sorted plug material, and the plug poking mechanism 19 pokes the plug on the plug receiving member 191 into the plug feeding member 152. Then, the plug feeding member 152 feeds the plug to the position of the capping operation, and the capping mechanism 17 operates to cap the plug on the container.

[0058] In some embodiments, the second conveying mechanism 12 can also be provided with a buffer station 120, which is located between the feeding station 122 and the first weighing station 123.

[0059] The buffer station 120 can provide a reserved space during the circulation of the containers driven by the first conveying mechanism 11, which can facilitate detection or other operations, and is also conducive to dealing with unexpected situations and preventing adverse situations from causing a large impact.

[0060] When the filling device provided in some embodiments of the present application performs the filling operation, the nest box with the nest plate 100 and the empty container is conveyed by the third conveying mechanism 101 to the nest plate feeding station 122, and the third transfer mechanism 102, i.e., the nest plate feeding mechanism, takes out the nest plate 100 in the nest box and places it on the first conveying mechanism 11, i.e., the nest plate conveying mechanism. The first conveying mechanism 11 conveys the nest plate 100 with the container to the transfer station 111, i.e., the container feeding station. The first transfer mechanism 13, i.e., the container feeding mechanism, transfers the container to the carrier 121 of the second conveying mechanism 12, and then sequentially passes through the pre-filling weighing station, the filling station 124, the post-filling weighing station, the post-filling nitrogen filling station, the capping station 126, the unqualified product rejection station, and the container unloading station. When the container is unloaded, if the second transfer mechanism 18 adopts the mode of vacuum suction for unloading the container, a cylinder needs to be added at the unloading station to assist in pushing the bottle to prevent the unloading failure. If the second transfer mechanism 18 adopts the clamping mode, this problem can be ignored. After the container is placed, the empty nest plate 100 is conveyed by the first conveying mechanism 11 to the nest plate unloading station, and the fourth transfer mechanism 103, i.e., the nest plate unloading mechanism, transfers the nest plate 100 at the conveying end of the first conveying mechanism 11 to the empty nest box on the third conveying mechanism 101.

[0061] As Figure 6The third transfer mechanism 102 is taken as an example to describe the transfer mechanism of the nest plate 100. The third transfer mechanism 102 can install the suction cup holder through the suction cup holder mounting plate 104 to suck the nest plate 100 through the suction cup. The suction cup holder mounting plate 104 can move with the belt pulley. The belt pulley includes a fixed wheel 105 and a movable wheel 106, the movable wheel 106 is connected with the suction cup holder mounting plate 104, and the fixed wheel 106 and a driving part can be installed on a support base 107. The speed reduction ratio of the fixed wheel 105 and the movable wheel 106 can be 1:1, which ensures that the direction of the suction cup holder mounting plate 104 is always unchanged. In actual cases, the third transfer mechanism 102 and the fourth transfer mechanism 104 can also use a gripper to clamp the nest plate 100 to transfer.

[0062] In actual cases, the nest plate 100 and the nest box are one-to-one corresponding, and are simultaneously moved and stopped. A sensor can be arranged before the empty container is weighed to detect whether there is a container on the platform 121. If there is no bottle or the bottle is missing, the weighing, filling and capping are not performed. A sensor can be arranged at the capping station 126 to detect whether the capping is successful, and to determine whether the product needs to be rejected.

[0063] The filling device provided by some embodiments of the present application can reduce the risk of broken bottles, reduce the size of the device, and improve the production efficiency.

[0064] Those skilled in the art can understand that the above-mentioned embodiments are specific embodiments for implementing the present application, and in actual applications, various changes can be made in form and details without departing from the spirit and scope of the present application.
