[0001] The present application relates to the technical field of filling equipment, in particular to a filling and plugging device. BACKGROUND
[0002] With the continuous development of automatic filling technology, automatic filling equipment has been applied in various fields, such as food, medicine, medical packaging, etc. The filling equipment can realize the automatic flow of containers and perform filling work during the container flow. After the filling work is completed, the plugging work is performed by the plugging device.
[0003] The plugging device is an important part of the filling equipment. During the plugging work, the bottle plug is transferred to the plugging station and installed in the bottle mouth. The structure of the plugging device affects the production efficiency. Therefore, how to improve the production efficiency of the plugging work is an important problem. CONTENT OF THE INVENTION
[0004] The purpose of the embodiment of the present application is to provide a filling and plugging device which can improve the production efficiency of the plugging work.
[0005] To solve the above technical problems, the embodiment of the present application provides a filling and plugging device. The filling and plugging device comprises a support, a fixing member, a blocking member and a pressing assembly. The fixing member is connected with the support, and the fixing member is provided with a plurality of hollow areas, each of which is used for positioning the bottle plug. The blocking member is rotationally connected with the fixing member, and the blocking member can be transformed between a first state and a second state. In the first state, the blocking member is close to the hollow area and located on the moving path of the bottle plug in the hollow area, and supports the bottle plug in the hollow area. In the second state, the blocking member is away from the gap and leaves the moving path of the bottle plug in the hollow area. The pressing assembly is movably arranged on the support, and the pressing assembly comprises a plurality of plug pressing members corresponding to the plurality of hollow areas, each of which can enter the corresponding hollow area and drive the bottle plug to pass through the hollow area.
[0006] The filling and plugging device provided by the embodiment of the present application uses the fixing member with hollow areas to provide accommodation space for the bottle plug, and the number of hollow areas is multiple, which can accommodate a large number of bottle plugs at one time. The blocking member can prevent the bottle plug from falling during the plugging work, and exit the moving path of the bottle plug when the pressing assembly performs the pressing work. Then the pressing work of a large number of bottle plugs is completed synchronously by the pressing assembly. Thus, the production efficiency of the plugging work is improved.
[0007] In some embodiments, the fixing member comprises a first side and a second side arranged oppositely, the plurality of hollowed regions are arranged adjacent to the first side, and the first side is provided with a plurality of openings corresponding to the plurality of hollowed regions. In this way, the bottle plug can be conveniently moved into the hollowed regions through the openings on the side of the fixing member.
[0008] In some embodiments, the edge of the blocking member is arranged spaced apart from the first side of the fixing member. In this way, by arranging the edge of the blocking member spaced apart from the first side of the fixing member, the range of the blocking member shielding the hollowed regions can be reduced, and the rotation angle of the blocking member during state transformation can be reduced.

[0010] In some embodiments, the edge of the blocking member is provided with a plurality of grooves corresponding to the plurality of hollowed regions, both ends of each groove penetrate through the blocking member, and in the first state, each groove accommodates part of the bottle plug. In this way, by arranging the grooves, the lifting area of the bottle plug by the blocking member can be reduced, and the rotation angle of the blocking member during state transformation can be reduced.
[0011] In some embodiments, the width of the groove is greater than the diameter of the plug member. In this way, by making the width of the groove greater than the diameter of the plug member, interference between the blocking member and the plug member when the blocking member returns to the initial position can be avoided.
[0012] In some embodiments, the filling plug device further comprises an elastic member, one end of the elastic member is connected with the fixing member, the other end of the elastic member is connected with the blocking member, and the elastic member can drive the blocking member to change from the second state to the first state under the elastic restoring force. In this way, by arranging the elastic member, automatic resetting of the blocking member can be realized.
[0013] In some embodiments, the elastic member has a plurality of elastic members, and the plurality of elastic members are distributed on the opposite sides of the fixing member. In this way, by arranging a plurality of elastic members, the stability of the blocking member during rotation can be ensured.
[0014] In some embodiments, each plug member is provided with a central hole, and the filling assembly further comprises a suction cup connected with the hole wall of the central hole and exposed on the surface of the plug member. In this way, by arranging the suction cup, the bottle plug can be fixed when being moved by the plug member.
[0015] In some embodiments, the plurality of hollowed-out regions are arranged uniformly in the same direction at the edge of the fixing member.

[0026] In the description of the embodiments of the present application, unless otherwise explicitly specified and limited, the technical terms "mounting", "connection", "connecting" and the like should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or integral; can be mechanical connection, can also be electrical connection; can be direct connection, can also be indirect connection through an intermediate medium, can be internal communication of two elements or interaction relationship between two elements. 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.
[0027] The filling and capping device can be used in automatic filling equipment in the fields of food, medicine, medical aesthetics, daily chemical sub-packaging, etc., for example, can be used in automatic filling production of penicillin bottles. The filling and capping device can perform capping work on the container to realize the function of capping, and can also be used for other containers in the working condition of pressing type capping or covering.
[0028] At present, in the automatic filling and capping work of the automatic filling line, a two-axis manipulator is used to drive a vacuum suction tube to vacuum suck the stopper from the stopper taking station Figure 7 to the capping station for capping work. However, the two-axis manipulator has high cost, large space occupation, and low production efficiency.
[0029] In order to improve the production efficiency of the capping work, some embodiments of the present application provide a filling and capping device. The filling and capping device provides a containing space for the stopper by using a fixed part with a hollow region, the number of the hollow regions is multiple, and a large number of stoppers can be simultaneously contained in one pressing work. The blocking part can prevent the stopper from falling during the capping work, and withdraw from the movement path of the stopper when the pressing assembly performs the pressing work. Then, the pressing work of a large number of stoppers is completed synchronously by the pressing assembly. Thus, the production efficiency of the capping work is improved.
[0030] The structure of the filling and capping device provided by some embodiments of the present application will be described below. Figures 1 to 6
[0031] As Figures 1 to 6 As shown, the filling and capping device provided by some embodiments of the present application includes a support 11, a fixing member 12, a blocking member 13 and a pressing assembly 14. The fixing member 12 is connected with the support 11, and the fixing member 12 is provided with a plurality of hollowed-out regions 121, each of which is used for positioning a bottle plug 21. The blocking member 13 is rotationally connected with the fixing member 12, and the blocking member 13 can be transformed between a first state and a second state. In the first state, the blocking member 13 is close to the hollowed-out regions 121 and is located on the moving path of the bottle plug 21 in the hollowed-out regions 121, and supports the bottle plug 21 in the hollowed-out regions 121. In the second state, the blocking member 13 is away from the hollowed-out regions 121 and leaves the moving path of the bottle plug 21 in the hollowed-out regions 121. The pressing assembly 14 is movably arranged on the support 11, and the pressing assembly 14 includes a plurality of pressing members 141 corresponding to the plurality of hollowed-out regions 121, each of which can enter the corresponding hollowed-out region 121 and drive the bottle plug 21 to pass through the hollowed-out region 121.
[0032] The support 11 is a part of the filling and capping device for providing a mounting basis for other components, and meanwhile, the support 11 can be connected in the filling equipment, so as to integrate the filling and capping device in the filling equipment. The support 11 can adopt the form of a support seat and a connecting arm in cooperation, so as to mount the components in a position facilitating cooperation.
[0033] The fixing member 12 is a component for providing a placing space for the bottle plug 21. The fixing member 12 is connected with the support 11 and is kept in a relatively fixed state. The hollowed-out regions 121 provided on the fixing member 12 are adapted to the contour of the bottle plug 21, and the bottle plug 21 can be accommodated in the hollowed-out regions 121 of the fixing member 12 during the capping operation. The hollowed-out regions 121 can be through holes provided on the fixing member 12 or notches provided at the edge of the fixing member 12. The plurality of hollowed-out regions 121 can be arranged along the direction indicated by the arrow S in FIG. 1. Figure 2
[0034] The blocking member 13 is a component cooperating with the fixing member 12. The blocking member 13 is rotationally connected with the fixing member 12 and can rotate relative to the fixing member 12. The blocking member 13 can transform states during rotation, and in different states, the blocking member 13 is located at different positions relative to the fixing member 12. In the first state, the blocking member 13 is close to the hollowed-out regions 121 of the fixing member 12 and is located on the moving path of the bottle plug 21 in the hollowed-out regions 121. When the blocking member 13 is in the first state, it can prevent the bottle plug 21 in the hollowed-out regions 121 from falling out and plays a role of supporting the bottle plug 21. When the blocking member 13 is transformed into the second state, the blocking member 13 is away from the hollowed-out regions 121 of the fixing member 12 and leaves the moving path of the bottle plug 21 in the hollowed-out regions 121. When the blocking member 13 is in the second state, it can facilitate the movement of the bottle plug 21 during the capping operation and will not affect the movement of the bottle plug 21 to the position of the bottle mouth of the container.
[0035] The pressing assembly 14 is used to move the bottle stopper 21 to perform the stoppering operation. The pressing assembly 14 can move relative to the fixed part 12, and the stoppering part 141 of the pressing assembly 14 moves the bottle stopper 21 during the movement and finally makes the bottle stopper 21 enter the bottle mouth of the container. The stoppering part 141 can adopt the form of clamping or adsorbing to fix the bottle stopper 21 during the movement of the bottle stopper 21. The stoppering part 141 is arranged in correspondence with the hollowed area 121 on the fixed part 12, and through the synchronous movement of the plurality of stoppering parts 141, the stoppering operation of the bottle stopper 21 in the plurality of hollowed areas 121 can be completed at the same time.
[0036] The filling and stoppering device provided by some embodiments of the present application adopts the fixed part 12 with the hollowed area 121 to provide the accommodation space for the bottle stopper 21, the number of the hollowed areas 121 is multiple, and a large number of bottle stoppers 21 can be accommodated at the same time in one stoppering operation. The blocking part 13 can prevent the bottle stopper 21 from falling during the stoppering operation and withdraw from the movement path of the bottle stopper 21 when the pressing assembly 14 performs the stoppering operation. Then, the stoppering operation of a large number of bottle stoppers 21 is completed synchronously by the pressing assembly 14. Therefore, the production efficiency of the stoppering operation is improved.
[0037] As shown in FIGS. 1, 2 and 3, the fixed part 12 includes the first side 122 and the second side 123 arranged oppositely, and the plurality of hollowed areas 121 are arranged adjacent to the first side 122, and the first side 122 is provided with the plurality of openings 124 corresponding to the plurality of hollowed areas 121. Figure 2 Figure 3 The opening 124 makes the hollowed area 121 communicate with the outside at the side of the fixed part 12 with smaller area, thereby facilitating the bottle stopper 21 to be pushed into the hollowed area 121 along the position of the opening 124. The fixed part 12 as the stoppering part can make the opening 124 at the side edge face the part of the bottle stopper 21 to be conveyed. In this way, after the bottle stopper 21 is conveyed, the bottle stopper 21 can directly enter the hollowed area 121 of the fixed part 12 through the opening 124, which simplifies the form of the bottle stopper 21 entering the accommodation space of the fixed part 12. Therefore, the production efficiency of the stoppering operation is improved.
[0038] In some embodiments, the edge of the blocking part 13 and the first side 122 of the fixed part 12 can be arranged at intervals.
[0039] In some embodiments, the edge of the blocking part 13 and the first side 122 of the fixed part 12 can be arranged at intervals.
[0040] That is, the edge of the blocking piece 13 is in a non-aligned state with the first side surface 122 of the fixing piece 12. The edge of the blocking piece 13 only shields part of the hollowed-out area 121, and supports the bottle plug 21 in the hollowed-out area 121. By spacing the edge of the blocking piece 13 from the first side surface 122 of the fixing piece 12, the shielding range of the blocking piece 13 on the hollowed-out area 121 can be reduced, which facilitates the blocking piece 13 to exit the movement path of the bottle plug 21 at a smaller angle, and gives way to the movement of the bottle plug 21.
[0041] When the blocking piece 13 is connected to the fixing piece 12, mounting pieces 127 can be arranged on opposite sides of the fixing piece 12 to realize the rotational connection between the blocking piece 13 and the fixing piece 12. The mounting pieces 127 can simplify the cooperation structure between the fixing piece 12 and the blocking piece 13. The mounting pieces 127 can be connected to the opposite sides of the fixing piece 12 by screws or other fasteners, and the rotating shafts protruding from the two sides of the blocking piece 13 can be inserted into different fixing pieces 12, thereby realizing the rotational connection between the blocking piece 13 and the fixing piece 12.
[0042] In some embodiments, the side of the fixing piece 12 close to the blocking piece 13 can be provided with a plurality of limiting structures corresponding to the plurality of hollowed-out areas 121, and each limiting structure includes a first limiting portion 125 and a second limiting portion 126 arranged opposite to each other. Figure 3 As shown in the figure, the first limiting portion 125 and the second limiting portion 126 are arranged adjacent to the first side surface 122, and the first limiting portion 125 and the second limiting portion 126 extend into the corresponding hollowed-out area 121 in a direction close to each other.
[0043] The limiting structure can play a limiting role at a position close to the opening 124 on the first side surface 122. When the bottle plug 21 is pushed into the hollowed-out area 121 through the opening 124 by an external force, the first limiting portion 125 and the second limiting portion 126 extending into the hollowed-out area 121 can support the bottle plug 21. Thus, it is beneficial for the bottle plug 21 to smoothly transition into the hollowed-out area 121 and reach the supporting position of the blocking piece 13. The limiting portion can be formed by a protruding portion arranged on one side of the fixing piece 12. Meanwhile, the limiting portion located between two hollowed-out areas 121 can be formed by the same protruding portion.
[0044] In some embodiments, the edge of the blocking piece 13 can be provided with a plurality of grooves 131 corresponding to the plurality of hollowed-out areas 121, and both ends of each groove 131 penetrate the blocking piece 13. In the first state, each groove 131 is used to accommodate part of the bottle plug 21.
[0045] The groove 131 at the edge of the blocking member 13 corresponds to the hollow area 121 at the edge of the fixing member 12. The groove 131 provides a receiving space for part of the bottle stopper 21, so that the bottle stopper 21 can be removed from the moving path when rotated at a small angle relative to the fixing member 12. The two ends of the groove 131 penetrate the blocking member 13, and the groove 131 forms a clearance area on the side of the blocking member 13 with a smaller area. The groove 131 is arc-shaped, and the size of the groove 131 in the preset direction is smaller than the diameter of the head 211 of the bottle stopper 21. When the blocking member 13 is in the first state, the part of the blocking member 13 near the groove 131 surrounds the insertion part 212 of the bottle stopper 21 inserted into the bottle mouth. The head 211 of the bottle stopper 21 abuts against the surface of the blocking member 13 and is supported and held within the hollow area 121 of the fixing member 12 by the blocking member 13.
[0046] In some embodiments, the width of the groove 131 may be greater than the diameter of the pressure plug 141.
[0047] In this way, when the stopper 21 leaves the rotation path of the blocking member 13, the blocking member 13 can be controlled to return to the first state, avoiding interference between the blocking member 13 and the stopper 141.
[0048] like Figure 4 and Figure 5 As shown, an elastic element 15 can be provided between the blocking element 13 and the fixing element 12. The elastic element 15 can drive the blocking element 13 from the second state to the first state under the elastic restoring force.
[0049] The elastic element 15 can drive the blocking element 13 to achieve automatic reset. The elastic element 15 can elastically deform when the blocking element 13 moves away from the hollow area 121 of the fixing element 12. After the force from the pressure plug 141 on the blocking element 13 disappears, it drives the blocking element 13 to rotate towards the hollow area 121 of the fixing element 12. Thus, the rotation process of the blocking element 13 is controlled by the elastic restoring force of the elastic element 15. The elastic element 15 can be a spring, a sheet, or other elastic element. In practice, the elastic element 15 can be a tension spring, with suspension parts provided on the sides of both the fixing element 12 and the blocking element 13. The two ends of the tension spring can be hung on the suspension parts of different components. The tension spring prevents the blocking element 13 from rotating when no external force is applied.
[0050] In addition, there can be multiple elastic elements 15, and multiple elastic elements 15 are located on opposite sides of the fixing element 12.
[0051] By increasing the number of elastic elements 15, the strength of the connection between the blocking element 13 and the fixing element 12 can be ensured. At the same time, distributing multiple elastic elements 15 on opposite sides of the fixing element 12 can ensure the stability of the blocking element 13 during rotation.
[0052] likeFigure 6 As shown, each pressure plug 141 may be provided with a central hole 142, and the pressure assembly 14 also includes a suction cup 143, which is connected to the hole wall of the central hole 142 and exposed on the surface of the pressure plug 141.
[0053] The central hole 142 can form a passage communicating with the vacuum pump. The pressing assembly 14 can be connected to the vacuum pump through the connector 144, thereby controlling the suction cup 143 to adsorb the bottle stopper 21. This ensures that the bottle stopper 21 can be moved stably during the pressing operation.
[0054] In some embodiments, a plurality of hollowed-out areas 121 may be evenly arranged in the same direction at the edge of the fastener 12.
[0055] like Figure 2 As shown, multiple hollow areas 121 can be evenly arranged along the direction indicated by arrow S, and the number of hollow areas 121 can be set to ten. By evenly arranging multiple hollow areas 121, the regularity of the arrangement of each component can be ensured, which is beneficial to the smooth operation of the filling equipment. In practice, the number of hollow areas 121 can also be set to five, six, seven, or eight.
[0056] In some embodiments of this application, the filling and capping device provides the following: During the capping operation, the hollow area 121 of the fixing member 12 receives the bottle stopper 21, and the blocking member 13 supports the bottle stopper 21 to ensure that it does not fall off. The capping assembly 14 descends and activates a vacuum, sucking up the upper surface of the bottle stopper 21 and continuing to descend until the bottle stopper 21 is installed on the bottle neck. During the descent of the capping assembly 14, a downward force is applied to the bottle stopper 21 and acts on the blocking member 13, causing the blocking member 13 to rotate and move away from the movement path of the bottle stopper 21 without affecting the descent of the bottle stopper 21. During the descent of the capping assembly 14, the bottle stopper 21 will disengage from the blocking member 13, and the blocking member 13 will be pulled back to its original position by the tension of the tension spring. Furthermore, the outer diameter of the capping member 141 of the capping assembly 14 is smaller than the size of the groove 131 of the blocking member 13, so the descent of the capping assembly 14 does not affect the return of the blocking member 13 to its original position.
[0057] Those skilled in the art will understand that the above embodiments are specific implementations of this application, and in practical applications, various changes can be made in form and detail without departing from the spirit and scope of this application.
