Description

Technical Field

[0001] The utility model relates to a capping machine, in particular to a standing bag filling and capping machine. Background Art

[0002] The turntable stand-up pouch filling and capping machine can automatically complete the filling of stand-up pouches and the installation of sealing caps in sequence.

[0003] China's published patent (CN115783443A) discloses a turntable self-supporting bag filling and capping machine with an increased number of workstations, including a frame, a turntable, and a turntable driving mechanism. The direction in which the spiral ascending channel of the lid on the inner side wall of the vibrating disk body extends is opposite to the direction in which the turntable rotates. The cap delivery channel of the capping mechanism is tangent to different sides of the vibrating disk body and the turntable, respectively. The tangent point between the cap delivery channel of the capping mechanism and the turntable is an improved capping station that replaces the original capping station. The beneficial effect of the present invention is that, due to the improvement of the structure, the position of the improved capping station can replace the original capping station and be changed to a place closer to the previous station, so that at least one station can be added to the section extending from the improved capping station to the first station according to the processing sequence, so that the number of stations can be increased to install the corresponding functional components, so that the production line can add more processing stations and functional components without increasing the space occupied by the production line to meet the production needs.

[0004] However, in combination with its processing process, it can be seen that in the screw-on capping part, when the self-supporting bag is conveyed from the bag feeding mechanism to the rotating platform, it needs to cooperate with other auxiliary parts for conveying and positioning, and the self-supporting bag may shake during the conveying process, affecting the subsequent filling, screwing on the cap and other processing steps.

DETAILED DESCRIPTION

[0030] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0031] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0032] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0033] See also Figure 1-Figure 3In the embodiment of the utility model, a self-supporting bag filling and capping machine comprises a base 1 and a frame 3 installed on the base 1, and a conveying platform 11 is arranged on the base 1, and the conveying platform 11 forms a loading position, a filling position, a capping position, a capping position and a unloading position relative to the base 1, and the loading position, the filling position, the capping position and the capping position correspond to the bag feeding mechanism 10, the filling mechanism, the capping machine 9 and the capping mechanism arranged along the circumference of the conveying platform 11 in sequence; the bag feeding mechanism 10 is used to convey the packaging bag toward the loading position, and then the conveying platform 11 can convey the packaging bag to the filling position, and the arranged filling mechanism pours an equal amount of material into the packaging bag. After the filling is completed, the conveying platform 11 continues to rotate to the capping position, and the capping machine 9 makes the threaded cap contact with the packaging bag for the first time, and then when it reaches the capping position, the threaded cap is tightened on the packaging bag through the capping mechanism, and finally falls out automatically from the unloading position, so as to realize automatic packaging of the material, and the degree of automation is high.

[0034] It should be noted that the filling and capping machine provided in this embodiment can be used for automatic filling and packaging of liquid beverages or paste beverages, etc. The packaging bags mentioned above include but are not limited to stand-up bags.

[0035] For further information, see Figure 5-Figure 8 The conveying platform 11 includes an arc-shaped seat 1102 fixed on the base 1 and a turntable 1101 that can rotate relative to the arc-shaped seat 1102. The turntable 1101 is driven to rotate intermittently by a driving member 5 installed on the base 1. A plurality of U-shaped notches 11012 for placing packaging bags are equidistantly arranged on the turntable 1101 along the circumferential direction, and when the U-shaped notch 11012 and the arc-shaped seat 1102 are staggered along the plumb direction, the notch of the U-shaped notch 11012 is blocked, wherein the two side edges of the U-shaped notch 11012 are a short side 11012a and a long side 11012b, respectively, and the direction of the long side 11012b toward the short side 11012a is the same as the rotation direction of the turntable 1101.

[0036] The arc seat 1102 is connected to a plurality of fixing frames 1103 installed on the base 1 , and the fixing frames 1103 are used to effectively support the arc seat 1102 .

[0037] The U-shaped notch 11012 on the turntable 1101 is used to place the spiral opening of the stand-up bag (the position between the spiral opening and the bag body). After the stand-up bag enters the U-shaped notch 11012, it can rotate with the turntable 1101, thereby realizing the successive position change of the stand-up bag at multiple stations.

[0038] In this embodiment, when one of the U-shaped notches 11012 rotates to the bag feeding mechanism 10, due to the setting of the long side 11012b of the U-shaped notch 11012, the self-supporting bag can be taken out from the bag feeding mechanism 10, and at the same time, it enters the U-shaped notch 11012 under the guiding action of the end of the arc seat 1102, thereby realizing automatic positioning of the self-supporting bag. At the same time, the inner arc surface of the arc seat 1102 blocks the U-shaped notch, so that the self-supporting bag maintains a vertical position without changing when rotating with the turntable 1101, which is convenient for subsequent filling, cap feeding and cap screwing operations, and does not require clamping and fixing, thereby reducing the use of mechanical parts. The overall structure is simple and has high stability.

[0039] Preferably, an embedded groove 11011 is further provided on the rotating disk 1101 at the position of the U-shaped notch 11012 to achieve positioning and limiting of the side end of the spiral opening of the stand-up bag.

[0040] For further information, see Figure 7 and Figure 8 The arc seat 1102 is also provided with a blanking notch 11021 , and an inclined material blocking portion 11022 is formed on the end of the blanking notch 11021 along the rotation direction of the turntable 1101 .

[0041] When the self-supporting bag after capping follows the turntable 1101 to rotate to the blanking notch 11021, the opening of the U-shaped notch 11012 loses its obstruction. When the self-supporting bag continues to follow the turntable 1101 to rotate to the inclined material blocking part 11022, it moves out of the U-shaped notch 11012 under the action of the inclined material blocking part 11022, thereby realizing automatic discharging of the self-supporting bag after packaging, with a high degree of automation.

[0042] Among them, a material guide 4 is installed on the base 1 at a position directly below the material blanking notch 11021. The self-supporting bag falling out of the material blanking notch 11021 falls onto the material guide 4 and falls into a pre-prepared collection box or collection bucket under the action of the material guide 4.

[0043] For further information, see Figure 5 , Figure 6 , Figure 9-11 The bag feeding mechanism 10 includes a mounting frame 1001 mounted on the base 1, and a first support plate 1003 and a second support plate 1004 are fixed on the mounting frame 1001 and are located on the same horizontal plane. The gap between the first support plate 1003 and the second support plate 1004 forms a material guide trough 1006, and also includes a pushing member fixed on the mounting frame 1001, and the pushing member is used to transport the packaging bag placed in the material guide trough 1006 toward the turntable 1101.

[0044] Since the material guide trough 1006 is arranged in a long strip shape, a plurality of packaging bags can be placed in the material guide trough 1006 at equal distances, thereby cooperating with the pushing member to realize sequential conveyance of the packaging bags.

[0045] Preferably, an arc-shaped guide groove 1005 is formed on one end of the first support plate 1003 and the second support plate 1004 toward the turntable 1101, and the arc-shaped guide groove 1005 is connected to the material guide groove 1006. The arc length direction of the arc-shaped guide groove 1005 is different from the rotation direction of the U-shaped notch 11012 following the turntable 1101, so that when the turntable 1101 rotates to the material guide groove 1006 to obtain a position, the long side 11012b of the U-shaped notch 11012 abuts against the spiral mouth of a self-supporting bag, and pushes the self-supporting bag to move out along the arc-shaped guide groove 1005. At the same time, under the action of the arc-shaped guide groove 1005, a certain squeezing effect is exerted on the self-supporting bag, so that the self-supporting bag enters the inner side of the U-shaped notch 11012, thereby realizing self-conveying and positioning of the self-supporting bag, and effectively eliminating the complexity of subsequently using other auxiliary equipment to reposition the self-supporting bag.

[0046] Exemplarily, in one embodiment, the pushing member includes a linear drive 1002 mounted on the mounting frame 1001, and a material tapping member 1007 is installed on the movable end of the linear drive 1002. Preferably, the material tapping member 1007 is hinged to the movable end of the linear drive 1002, and a limit block is also fixed on the movable end of the linear drive 1002. The limit block limits the material tapping member 1007, so that the material tapping member 1007 can only rotate in the conveying direction of the self-supporting bag when it is in a vertical state, thereby maintaining a vertical state when the material tapping member 1007 performs a material tapping action, and when the material tapping member 1007 is reset, it will not push the self-supporting bag subsequently placed in the guide groove 1106 in the opposite direction.

[0047] See also Figure 1-Figure 4 The filling mechanism includes a material storage tank 2 and a pumping mechanism 12 installed on the base 1, and the pumping mechanism 12 is connected to the material storage tank 2 through a conduit; it also includes at least one filling head 7 connected to the pumping mechanism 12, and the filling head 7 is installed on the frame 3 and can move in a vertical direction to be in sealing contact with the packaging bag during filling. Preferably, a stirring member 201 is provided in the material storage tank 2.

[0048] The pumping mechanism 12 is provided to pump the material (beverage or other liquid substance) in the storage tank 2 into the filling head 7, and inject it into the self-supporting bag through the filling head 7, wherein the filling head 7 moves down during filling to seal and contact with the self-supporting bag to achieve filling. The filling head 7 is a vacuum filling head, which belongs to the use of conventional components, and therefore, this embodiment will not be described in detail.

[0049] For an exemplary embodiment, please refer to Figure 2 and Figure 4 The pumping mechanism 12 includes a support frame 1204 installed on the base 1 and at least one piston cylinder 1201 (including a cylinder body, a piston and a connecting rod) installed on the support frame 1204 and connected to the filling head 7. The piston cylinder 1201 is driven by an electric telescopic rod 1205 installed on the support frame 1204 to perform the pumping action. Of course, in order to ensure the stability of the pumping of the piston cylinder 1201, a connecting plate 1202 is fixed to the movable end of the electric telescopic rod 1205. The connecting plate 1202 is connected to the piston cylinder 1201, and a guide rod 1203 slidably connected to the support frame 1204 is fixed on the connecting plate 1202. The connecting plate 1202 is driven to move up and down reciprocatingly by the electric telescopic rod 1205, thereby driving the piston cylinder 1201 to perform the pumping action.

[0050] For another exemplary embodiment, please refer to Figure 3 , the above-mentioned electric telescopic rod 1205 is replaced by a cylinder 1206.

[0051] See also Figure 1 The capping mechanism includes a lifting drive member 8 installed on the frame 3, and the movable end of the lifting drive member 8 is connected to the capping member 6 through a movable frame, wherein the capping member 6 includes a motor 604 installed on the movable frame, and a driving shaft 603 is fixed to the movable end of the motor 604, and a capping head 601 is slidably installed at one end of the driving shaft 603 away from the motor 604, and the capping head 601 is in contact with an elastic member 602 sleeved on the driving shaft 603.

[0052] The lifting drive member 8 includes but is not limited to a cylinder, and the lifting drive member 8 drives the screw cap member 6 to move up and down to tighten the threaded cover and the self-supporting bag thread. The screw cap member 6 is a commonly used screw cap structure, so it will not be described in detail in this embodiment.

[0053] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
