Description

TECHNICAL FIELD

[0001] The utility model relates to infusion bag production technical field especially, relates to a kind of infusion bag mouth pipe pre-pressing positioning device. BACKGROUND

[0002] The automatic production process of non-PVC membrane infusion soft bag includes bag making, filling, sealing and other key procedures. At the bag making station, the bag making, filling and sealing machine completes the production of the bag body, and the bag body is placed into the annular clamp 2 shown in the drawing by the bag placing manipulator at the bag placing station. Under the control of the control system, the annular clamp 2 moves along the conveying track 1. Moreover, a clamping hand 21 for clamping and limiting the bag mouth pipe 61 part on the infusion bag 6 is provided on one side of the annular clamp 2. At the bag placing station, the infusion bag 6 is placed into the clamping hand 21 of the annular clamp 2, and the infusion bag 6 is then driven into the filling station and continuously transferred between subsequent stations under the driving of the annular clamp 2. Figures 1-3

[0003] However, in the actual production process, since the infusion bag 6 is hung on the annular clamp 2, the bag mouth pipe 61 part is in a free state without constraint, which leads to the uncertainty of the position of the entire infusion bag 6 and the inability to achieve accurate positioning of the bag mouth. This positioning deviation can cause a series of problems: first, in the filling process, since the position of the bag mouth pipe 61 is uncertain, the infusion liquid is difficult to flow accurately into the infusion bag 6, which can cause inaccurate filling amount, liquid overflow and other situations, resulting in a decrease in product qualification rate; second, in the sealing process, the position deviation of the bag mouth pipe 61 can cause the sealing position deviation, which can cause serious quality problems such as loose sealing and liquid leakage, resulting in material waste and a great safety hazard.

[0004] Therefore, a device capable of accurately positioning the bag mouth pipe 61 needs to be developed to achieve rapid and accurate positioning of the infusion bag 6 at subsequent stations and to ensure the production quality and efficiency of the infusion bag. UTILITY MODEL CONTENTS

[0005] In view of the problems existing in the prior art, the position of the infusion soft bag on the annular clamp is uncertain, accurate positioning of the bag mouth pipe cannot be achieved, and the subsequent filling process is seriously affected.

[0006] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows: ​An infusion bag pre-compression positioning device is provided for fully pressing the infusion bag opening tube into the gripper of an annular clamp. The bag opening tube is located inside the gripper. Multiple annular clamps are spaced apart on a conveyor track. The device includes a frame and a pressing mechanism and a pushing mechanism fixed on the frame. The pressing mechanism includes a first driving member and a pressure plate. The pressure plate is horizontally positioned and located directly above the gripper.

The pushing mechanism includes a second driving member and a push rod. The height of the push rod is the same as the height of the gripper, and the push rod faces the side of the gripper opening. The second driving member is fixedly connected to the push rod and drives the push rod to move closer to or away from the gripper in the horizontal direction.

[0007] The present invention is further configured such that the annular clamps are arranged at equal intervals on the conveying track, and the pressure plate simultaneously presses down on the bag opening tubes in the four clamps.

[0008] The present invention is further configured such that the annular clamps are arranged at equal intervals on the conveying track, and the push rod simultaneously pushes the bag opening tubes in the four clamps.

For ease of explanation, the terms "vertical", "horizontal", "left", "right", "upper", "lower", "inner", "outer", "bottom", etc., used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0019] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] As attached Figures 4-7 As shown, an infusion bag opening tube pre-compression positioning device includes a frame 3 and a pressing mechanism 4 and a pushing mechanism 5 fixed on the frame 3, used to completely press the bag opening tube 61 of the infusion bag 6 into the gripper 21 of the annular clamp 2.

[0021] The pre-compression positioning device in this invention is located between the bag-loading station and the filling station. At the bag-loading station, the bag-loading robot places the infusion bag 6 into the gripper 21 of the annular clamp 2. The annular clamp 2 moves along the conveying track 1 to the pre-compression positioning device and pauses conveying. After the bag opening tube 61 is positioned, the infusion bag 6 continues to enter the filling station along the conveying track 1 under the drive of the annular clamp 2.

[0022] Both the annular clamp 2 and the conveying track 1 are existing technologies. Multiple annular clamps 2 are equally spaced on the conveying track 1, and each annular clamp 2 is equipped with a gripper 21. The gripper 21 has a U-shaped opening. When the bag opening tube 61 on the infusion bag 6 is inserted into the gripper 21 through the opening, the infusion bag 6 is suspended on the annular clamp 2.

[0023] The frame 3 is composed of multiple support columns and connecting rods connected together, thus providing support and an installation platform for the entire positioning device.

[0024] The pressing mechanism 4 includes a first driving member 41, a guide rod 42, a fixed plate 43, a pressure plate 44, and an elastic buffer block 45.

[0025] The rack 3 includes a mounting base 31 for mounting the first drive unit 41. The mounting base 31 is located between the frame structure of the rack 3 and the first drive unit 41, thereby providing a mounting platform for the first drive unit 41.

[0026] In this embodiment, the first driving component 41 is an electric push rod, the axis of which is vertically arranged, and the bottom of the power output rod is fixedly connected to the fixed plate 43. The first driving component 41 is used to drive the fixed plate 43 to move up and down in the vertical direction.

[0027] The fixing plate 43 is a horizontally arranged flat plate structure. The center of its upper surface is fixedly connected to the power output rod of the first driving member 41, and the lower surface of the fixing plate 43 contacts and is fixedly connected to the pressure plate 44.

[0028] The guide rods 42 are cylindrical rod-shaped structures. Two guide rods 42 are vertically inserted into the mounting base 31 and slidably connected to the mounting base 31. The bottom of the guide rods 42 is fixedly connected to the fixed plate 43. When the first driving member 41 drives the fixed plate 43 to rise and fall, the guide rods 42 slide synchronously with the fixed plate 43 in the vertical direction. The guide rods 42 provide guidance for the up and down movement of the fixed plate 43 and the pressure plate 44, so that the fixed plate 43 and the pressure plate 44 remain stable during movement, improving the accuracy of downward positioning.

[0029] The pressure plate 44 is a rectangular plate structure, which is horizontally set and located directly above the clamp 21. The first driving member 41 drives the fixed plate 43 to rise and fall in the vertical direction, and at the same time drives the pressure plate 44 to rise and fall in the vertical direction.

[0030] The length of the pressure plate 44 is consistent with the conveying direction of the conveying track 1, and the length of the pressure plate 44 ensures that the pressure plate 44 can simultaneously press the bag opening tube 61 in the four clamps 21 when it is pressed down.

[0031] Four elastic buffer blocks 45 are provided on the lower surface of the pressure plate 44, and the elastic buffer blocks 45 are located directly above the gripper 21. The elastic buffer blocks 45 are made of silicone material. During the process of the pressure plate 44 pressing down on the bag opening tube 61, the elastic buffer blocks 45 gently press down on the bag opening tube 61, thereby avoiding damage to the bag opening tube 61 by the rigid compression of the pressure plate 44.

[0032] The pushing mechanism 5 is located below the pressing mechanism 4. The pushing mechanism 5 includes a second driving component 51 and a push rod 52.

[0033] The second drive unit 51 is fixed on the connecting rod of the frame 3. The second drive unit 51 is similar to the first drive unit 41 and can also be an electric push rod or other drive units, such as an electric cylinder or a pneumatic cylinder.

[0034] The second driving component 51 is fixedly connected to the push rod 52, thereby driving the push rod 52 to move.

[0035] The push rod 52 is a long, horizontal rod structure, with the same height as the gripper 21 and located on the side directly opposite the opening of the gripper 21. The length of the push rod 52 ensures that it can simultaneously push the bag opening tube 61 inside all four grippers 21.

[0036] The push rod 52 is provided with a positioning protrusion 521 facing the opening of the gripper 21. The positioning protrusion 521 is cylindrical, and its end facing the gripper 21 is provided with a hemispherical tip. The shape and size of the positioning protrusion 521 can be adapted to the opening of the gripper 21, so that the positioning protrusion 521 can be horizontally inserted into the opening of the gripper 21.

[0037] When the second driving member 51 drives the push rod 52 to approach the gripper 21 in the horizontal direction, the four positioning protrusions 521 are simultaneously inserted horizontally into the gripper 21, thereby completely pushing the bag opening tube 61 inside the gripper 21 into the gripper 21.

[0038] The implementation principle of the above embodiments is as follows: After passing the bag-loading station, the conveyor rail 1 delivers the annular clamp 2, with the infusion bag 6 suspended on it, to the positioning device. At this point, the pressure plate 44 is directly above the four grippers 21, and the four positioning protrusions 521 on the push rod 52 are aligned with the same four grippers 21. Then, the first drive unit 41 and the second drive unit 51 actuate, pressing the pressure plate 44 vertically downwards and pushing the push rod 52 horizontally, thus positioning the bag opening tube 61 vertically and horizontally, ensuring the bag opening tube 61 is fully in the set position within the grippers 21. Finally, the first drive unit 41 and the second drive unit 51 actuate, resetting the pressure plate 44 and the push rod 52, and the conveyor rail 1 delivers the infusion bag 6 to the next station.

[0039] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the present invention. Clearly, those skilled in the art can make various alterations and modifications to the present invention without departing from its spirit and scope. Thus, if such modifications and modifications fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include such modifications and modifications.
