Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of powder packaging, in particular to a connecting rod type bottle body clamping and positioning tool suitable for a high-speed packaging machine. Background Art
[0002] In the sterile liquid filling equipment, during normal operation, the vials move forward at a constant speed on the conveyor belt. The filling needle holder relies on mechanical transmission to maintain reciprocating synchronous motion with the vials, and the filling pump provides power for filling. The filling needle holder connects the filling needle and the liquid buffer tank through a medical-grade silicone hose. The overall weight of the filling needle holder is relatively light, and it has good stability when filling with the bottle. During the filling process of the liquid, the vial does not need to be positioned. The precise positioning of the servo control system and the combination of mechanical transmission can achieve the filling needle and the bottle mouth to be aligned for filling. It can be summarized that when the liquid is filled, the bottle is moving, and the bottle is kept aligned with the filling needle before filling.
[0003] However, in general powder filling equipment, the bottle is stationary when filling powder. This is because the liquid medicine is in liquid state and can be transmitted through pipes, while the powder medicine is in solid state. Solid powder cannot be transported to the filling buffer through a hose. The filling head has a certain weight, which is much heavier than the filling needle holder, and is not suitable for filling in a follow-up manner. Generally, during filling, the conveying device inside the filling equipment transports the vial to the lower side of the filling head, positions it and keeps it still, and then performs the powder filling action.
[0004] There are many ways to position vials on the filling equipment, such as using a cylinder to drive the positioning gripper, or using a star wheel to position the vials. During low-speed filling, there is no problem with the cylinder driving the positioning gripper to position the vials, but during high-speed filling, the speed and inertia of the cylinder itself are difficult to control, and the vials are easily knocked away. When using star wheels for positioning, although it can be applied to both high and low speeds, one star wheel can only position one bottle. If four bottles are to be filled, four sets of star wheels must be added, which will take up a lot of equipment space. Utility Model Content

[0036] When in use, the front clamping plate 304 and the rear clamping plate 404 can synchronously drive the front clamping plate 304 and the rear clamping plate 404 to perform reciprocating opening and closing movements under the reciprocating rotation of the connecting rod mechanism 200, thereby clamping or releasing the vial 700 on the conveying line body 500, so as to cooperate with the filling needle holder to perform powder packaging.
[0037] In some of the embodiments, Figure 1 and Figure 2As shown, in order to realize the synchronous opening and closing between the front clamping jaw mechanism 300 and the rear clamping jaw mechanism 400, the connecting rod mechanism 200 adopts a parallelogram connecting rod structure with small space occupation and compact structure, which mainly includes a supporting base plate 203, a driving shaft 204, a driven shaft 205, a left swing arm 206, a right swing arm 207, a front hinge plate 208 and a rear hinge plate 212.
[0038] Specifically, the driving shaft 204 and the driven shaft 205 are arranged vertically with left and right intervals, and the lower ends of the driving shaft 204 and the driven shaft 205 are rotatably mounted on the left and right ends of the support base plate 203 through bearings, and can reciprocate at a certain angle relative to the support base plate 203.

Preferably, the driving shaft 204 is used as the power shaft to connect the driving mechanism 600, which is limited by the square parallel structure design of the connecting rod mechanism 200, and can synchronously drive the driven shaft 205 to rotate.
[0039] The left swing arm 206 and the right swing arm 207 are parallel to each other and arranged horizontally at intervals, and the middle bottom positions thereof are fixedly connected to the top ends of the driving shaft 204 and the driven shaft 205, respectively, and the connection points can be set near the rear ends of the left swing arm 206 and the right swing arm 207.

[0040] like Figure 1 and Figure 2 As shown, the connecting rod mechanism 200 also includes a support seat 201 and a sleeve 202 coaxially arranged on the top of the support seat 201.

[0042] In addition, if Figure 1 and Figure 2 As shown, in order to reduce the volume of the device and improve the compactness of the structure of the device, a heightening pad 211 is provided at the top of the front hinge plate 208, and the top of the heightening pad 211 is fixedly connected to the proximal end of the front clamping jaw mechanism 300. And an extension plate 215 is provided on the front side wall of the rear hinge plate 212, and the top of the front end of the extension plate 215 is fixedly connected to the proximal end of the rear clamping jaw mechanism 400, so that the front clamping jaw mechanism 300 and the rear clamping jaw mechanism 400 are installed in a staggered manner.
[0043] In some of the embodiments, Figure 1 and Figure 2 As shown, the front clamp mechanism 300 includes a front connecting rod 301, a front sub-assembly plate 303 and a front clamping plate 304. The front connecting rod 301, the front sub-assembly plate 303 and the front clamping plate 304 can be designed as an integral structure, or welded to form an integral structure.
[0044] Specifically, the front connecting rod 301 is arranged horizontally, and its proximal end is fixedly connected to the heightening pad 211 on the connecting rod mechanism 200 by a first bolt 302, and its distal end is vertically connected to the horizontally arranged front sub-assembly plate 303. The front connecting rod 301 and the front sub-assembly plate 303 constitute a horizontally arranged T-shaped front clamp bracket.
[0045] The front sub-loading plate 303 is located at the left side of the conveying line body 500, and is provided with at least two spaced front clamping plates 304 to form at least two clamping claws at the left side of the conveying line body 500. The front clamping plates 304 are made of non-metallic materials, such as rubber or silicone, and have certain buffer elasticity.
[0046] In addition, as needed, a clamping groove 3041 can be opened on the clamping surface of the front clamping plate 304. The clamping groove 3041 is a triangular notch, which can cooperate with the rear clamping plate 404 to stably constrain the vial 700 in the triangular space, and is used to constrain the vial 700 and prevent the vial 700 from being smashed due to misoperation during debugging.
[0047] In some of the embodiments, Figure 1 and Figure 2 As shown, the rear clamp mechanism 400 includes a rear connecting rod 401, a rear sub-assembly plate 403 and a rear clamping plate 404. The rear connecting rod 401, the rear sub-assembly plate 403 and the rear clamping plate 404 can be designed as an integral structure, or welded to form an integral structure.
[0048] The proximal end of the rear connecting rod 401 is fixedly connected to the extension plate 215 on the connecting rod mechanism 200 by a second bolt 402, and the distal end thereof wraps around the bottom of the conveyor line body 500 and vertically connects to the horizontally arranged rear sub-loading plate 403. The rear connecting rod 401 and the front sub-loading plate 303 form a U-shaped rear clamp bracket.
[0049] The rear sub-packaging plate 403 is located on the right side of the conveyor line 500, and is provided with at least two rear clamps 404 arranged opposite to the front clamps 304, which can clamp and position multiple vials 700 at one time, and the bottle clamping efficiency is high. At least two clamps arranged opposite to the rear clamps 404 are formed on the left side of the conveyor line 500. The rear clamps 404 are made of non-metallic materials, such as rubber or silicone, and have a certain buffering elasticity. They are used to contact the vials 700 to prevent the vials 700 from being smashed by malfunction during debugging, and play a buffering role.
[0050] It is worth noting that Figure 1 As shown, in order to avoid the conveyor line body 500, the left side of the rear connecting rod 401 is connected to the connecting rod mechanism 200, and the right end is connected to the rear clamping plate 404. The rear connecting rod 401 adopts a U-shaped structure design, which surrounds the bottom of the conveyor line body 500 to the left side of the conveyor line body 500.
[0051] Furthermore, in some of the embodiments, Figure 1 As shown, in order to realize the reciprocating rotation of the connecting rod mechanism 200, a driving mechanism 600 is also provided at the bottom of the platform 100 of the positioning device. The driving mechanism 600 includes a servo motor 601 and a reducer 602. Compared with the cylinder bottle clamping, the servo motor has higher control accuracy, more stable start and stop control, and better bottle clamping accuracy.
[0052] The output shaft of the servo motor 601 is connected to the reducer 602, and the output shaft of the reducer 602 is connected to the driving shaft 204 of the connecting rod mechanism 200 through the coupling 603. When the servo motor 601 is started to run forward and reverse, the driving shaft 204 can be synchronously driven by the reducer 602 to reciprocate at a certain angle, and the rotation angle is 30-90°.
[0053] Combination Figure 1 and Figure 2As shown, the connecting rod type bottle body clamping and positioning tooling suitable for high-speed filling machines has the following working principle: the servo motor 601 cooperates with the reducer 601, and connects the driving shaft 204 through the coupling 603 to drive the connecting rod mechanism 200 to reciprocate, thereby driving the front clamping mechanism 300 and the rear clamping mechanism 400 to open and close. When the front clamping mechanism 300 and the rear clamping mechanism 400 are driven to merge, the syringe bottle 700 is constrained in the non-metallic triangular space. At this time, the filling motor starts and the filling action is performed. After the filling is completed, the front clamping mechanism 300 and the rear clamping mechanism 400 are driven to open. At this time, the syringe bottle 700 moves to several stations under the action of the conveyor line 500. The device reciprocates to play the role of filling and positioning.
