Description

Technical Field

[0001] The present invention relates to the technical field of soft bag large infusion production, more specifically, to a filling device. The present invention also relates to a soft bag large infusion bag making, filling and sealing machine. Background Art

[0002] In the fully automated production process for soft-bag infusions, the filling and sealing process begins with bag receipt and continues through processes such as bag receipt, filling, sealing, and off-line. The bag receiving station is the initial location where the filling and sealing machine receives the soft bags as they are transported from the bag-making machine (also known as the front car) to the filling and sealing machine (also known as the back car). The bag receiving station is equipped with a back car clamp with an opening assembly. The opening assembly is used to open the back car clamp, allowing the front car conveyor to place the soft bag on the back car clamp. The filling station is where liquid is poured into the soft bags. This station is equipped with a clamping assembly to secure the soft bag's hose for easy infusion.

[0003] Currently, the process from soft bags arriving at the bag receiving station to filling is completed by first transporting them from the bag receiving station to the filling station via a subsequent vehicle conveyor. At the filling station, the filling nozzle of the filling device is inserted into the flexible tube attached to the bag, holding the tube tightly for filling. After filling is complete, the bag is transported to the subsequent process. This independent process of conveying and filling the soft bags affects filling efficiency and, in turn, the production speed of soft bag large-volume infusion products.

[0004] Moreover, a conveying device for conveying the soft bags from the bag receiving station to the filling station and a filling device of the filling station are arranged separately, resulting in a large occupied space. Summary of the Invention

[0005] In view of this, the object of the present invention is to disclose a filling device to improve the filling efficiency and thereby increase the production speed of soft bag large infusion products.

[0006] Another object of the present invention is to disclose a soft bag large infusion bag making and filling machine with the above-mentioned filling device.

[0007] In order to achieve the above object, the present invention discloses the following technical solutions:

[0008] A filling device, comprising:

[0009] A frame, wherein the frame is provided with a bag receiving position for receiving soft bags and a bag filling completion position for outputting filled soft bags;

[0010] A filling body for filling liquid into a soft bag;

[0011] a conveying mechanism for driving the filling body to reciprocate between the bag receiving position and the bag filling completion position, the filling body being arranged at a driving end of the conveying mechanism;

[0012] Among them, the filling body includes a filling head that can be plugged in and out of the hose of the soft bag; a clamping component that can tighten and loosen the hose, the clamping component is arranged on the filling head, and when the filling head is inserted into the hose, the clamping component can tighten the hose on the filling head; a plug-in drive member for driving the plugging and unplugging of the filling head, and the driving end of the plug-in drive member is connected to the filling head.

[0013] Preferably, in the above filling device, the conveying mechanism includes:

[0014] a linear drive member disposed on the frame;

[0015] A connecting bracket connects the driving end of the linear drive member and the filling body, and the connecting bracket slides with the conveying slide rail on the frame along the linear driving direction of the linear drive member through a conveying guide slider.

[0016] Preferably, in the above filling device, the bag receiving position and the bag filling completion position are arranged vertically, and the linear driving direction of the linear driving member is a vertical direction.

[0017] Preferably, in the above filling device, the conveying mechanism further comprises a limiter for limiting the descending position of the driving end of the linear driving member, and the limiter is provided on the frame and below the connecting bracket and can abut against the bottom of the connecting bracket.

[0018] Preferably, in the above filling device, the insertion and removal direction of the filling head forms an angle with the vertical direction.

[0019] Preferably, in the above-mentioned filling device, the linear driving component is a lifting cylinder; and the plugging and pulling driving component is a plugging and pulling cylinder.

[0020] It can be seen from the above technical solution that the filling device disclosed in the present invention includes a frame, on which is provided a bag receiving position for receiving soft bags and a bag filling completion position for outputting filled soft bags; a filling body for filling liquid into the soft bags; a conveying mechanism for driving the filling body to reciprocate between the bag receiving position and the bag filling completion position, and the filling body is arranged at the driving end of the conveying mechanism; wherein, the filling body includes a filling head that can be plugged in and out of a hose of the soft bag; a clamping assembly that can clamp and loosen the hose, and the clamping assembly is arranged on the filling head. When the filling head is inserted into the hose, the clamping assembly can tighten the hose onto the filling head; a plug-in drive member for driving the plug-in and pull-out of the filling head, and the driving end of the plug-in drive member is connected to the filling head.

[0021] During application, the bag receiving position of the frame is arranged corresponding to the output end of the first conveying device for conveying the soft bags output by the bag making machine, and the bag filling completion position of the frame is arranged corresponding to the input end of the second conveying device for conveying the filled soft bags to the next process.

[0022] During the working process, the conveying mechanism is first used to convey the filling body to the bag receiving position. At this time, the first conveying device clamps the soft bag output by the bag making machine through the bag transfer clamp, and conveys the soft bag to a position opposite to the bag receiving position. Then, under the drive of the plug-in drive component, the filling head is inserted into the soft bag, and the soft bag is tightened on the filling head by the clamping component; then the bag transfer clamp is opened and the soft bag is released; then the filling body starts to fill, and the liquid medicine enters the soft bag through the filling head. During the filling process, the conveying mechanism drives the filling head to move forward and backward. The filling body moves toward the bag filling completion position until it is transported to the bag filling completion position. At this time, the filling clamp on the second conveying device corresponding to the bag filling completion position is opened; when the filling is completed, the filling clamp is closed to clamp the hose with the filling clamp, and then the clamping assembly releases the hose. At the same time, the filling head is pulled out of the hose under the drive of the plug-in drive member; finally, the conveying mechanism drives the filling body to the bag receiving position again and enters the next filling cycle. The second conveying device clamps the hose of the filled soft bag through the filling clamp and transports it to the next process.

[0023] It can be seen that the filling device provided by the present invention utilizes the filling body to directly receive the soft bag, and there is no need to use other tools to transport the soft bag, that is, the bag receiving process and the filling process are combined together, which simplifies the filling process; and in the process of the conveying mechanism conveying the filling body, the soft bag is filled by the filling body at the same time, which saves the time occupied by the filling liquid alone, thereby improving the filling efficiency and further improving the production speed of soft bag large infusion products.

[0024] In addition, the present invention arranges the filling body at the driving end of the conveying mechanism, that is, the filling body is integrated on the conveying mechanism, thereby reducing the occupied space.

Since the above-mentioned filling devices have the above-mentioned effects, the soft bag large infusion bag making and filling machine having the above-mentioned filling devices has the same effects, so they will not be described in detail herein.

[0026] Preferably, in the above-mentioned soft bag large infusion bag making and filling machine, the first conveying device includes a first slide rail provided on the first conveying surface of the frame, and the bag transfer fixture is slidably engaged with the first slide rail via a first slider;

[0027] The second conveying device includes a second slide rail provided on the second conveying surface of the frame, and the potting fixture is slidably engaged with the second slide rail via a second slider;

[0028] Wherein, there is a conveying gap between the first conveying surface and the second conveying surface for conveying the soft bag.

[0035] The embodiment of the present invention discloses a filling device, which improves the filling efficiency and further increases the production speed of soft bag large infusion products.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0037] Please refer to the attached Figure 1-3 The filling device disclosed in the embodiment of the present invention includes a frame 1, on which is provided a bag receiving position for receiving a soft bag and a bag filling completion position for outputting the filled soft bag; a filling body for filling liquid into the soft bag; a conveying mechanism for driving the filling body to reciprocate between the bag receiving position and the bag filling completion position, and the filling body is arranged at the driving end of the conveying mechanism; wherein, the filling body includes a filling head 4 that can be plugged in and out of a hose 10 of the soft bag; a clamping component 3 that can clamp and release the hose 10, and the clamping component 3 is arranged on the filling head 4. When the filling head 4 is inserted into the hose 10, the clamping component 3 can tightly cover the hose 10 on the filling head 4; a plug-in and pull-out driving member 5 for driving the plug-in and pull-out of the filling head 4, and the driving end of the plug-in and pull-out driving member 5 is connected to the filling head 4.

[0038] During application, the bag receiving position of the frame 1 is arranged corresponding to the output end of the first conveying device for conveying the soft bags output by the bag making machine, and the bag filling completion position of the frame 1 is arranged corresponding to the input end of the second conveying device for conveying the filled soft bags to the next process.

[0039] During the working process, the filling body is first transported to the bag receiving position by the conveying mechanism. At this time, the first conveying device clamps the soft bag hose 10 output by the bag making machine through the bag transfer clamp 2 and transports the soft bag to a position opposite to the bag receiving position, such as Figure 1 As shown, in order to simplify the structure diagram, only the hose 10 of the soft bag is shown in the figure; then, under the drive of the plug-in drive 5, the filling head 4 is inserted into the hose 10, and the hose 10 is tightly covered on the filling head 4 by the clamping component 3, as shown in FIG. Figure 2 As shown; then the bag transfer clamp 2 is opened and the hose 10 is released; then the filling body starts filling, and the liquid medicine enters the soft bag through the filling head 4. During the filling process, the filling body is simultaneously driven by the conveying mechanism to move toward the bag filling completion position until it is conveyed to the bag filling completion position. At this time, the filling clamp 9 on the second conveying device corresponding to the bag filling completion position is opened; when the filling is completed, the filling clamp 9 is closed to clamp the hose 10 with the filling clamp 9, and then the clamping component 3 is made to release the hose 10. At the same time, the filling head 4 is pulled out from the hose 10 under the drive of the plug-in drive 5, as shown Figure 3As shown; finally, the conveying mechanism drives the filling body to be transported to the bag receiving position again and enters the next filling cycle. The second conveying device clamps the filled soft bag with a hose 10 through the filling clamp 9 and transports it to the next process.

[0040] It can be seen that the filling device provided by the present invention utilizes the filling body to directly receive the soft bag, and there is no need to use other tools to transport the soft bag, that is, the bag receiving process and the filling process are combined together, which simplifies the filling process; and in the process of the conveying mechanism conveying the filling body, the soft bag is filled by the filling body at the same time, which saves the time occupied by the filling liquid alone, thereby improving the filling efficiency and further improving the production speed of soft bag large infusion products.

[0041] In addition, the present invention arranges the filling body at the driving end of the conveying mechanism, that is, the filling body is integrated on the conveying mechanism, thereby reducing the occupied space.

[0042] In a specific embodiment, the conveying mechanism includes a linear drive member 6 mounted on the frame 1; a connecting bracket 7 connecting the driving end of the linear drive member 6 to the filling body; the connecting bracket 7 slides along the linear drive direction of the linear drive member 6 via a conveying guide slider and a conveying rail on the frame 1. In this embodiment, the conveying mechanism provides a linear driving force through the linear drive member 6, driving the connecting bracket 7 and the filling body to move linearly, thereby achieving reciprocating motion of the filling body between a bag receiving position and a bag filling completion position. During this motion, the conveying guide slider slides back and forth along the conveying rail to guide the movement direction of the filling body, thereby improving the accuracy of the filling body's movement position.

[0043] The connecting bracket 7 facilitates the assembly of the driving end of the linear driving member 6 and the filling body, and the filling body can also be directly connected to the linear driving member 6.

[0044] The conveying mechanism of the above structure is relatively simple and further reduces the space occupied. It is understood that the conveying mechanism can also adopt other structural forms, such as a belt transmission mechanism or a chain transmission mechanism that uses a rotating drive member to provide rotational force to achieve reciprocating movement of the filling body between the bag receiving position and the bag filling completion position.

[0045] In a further technical solution, the bag receiving station and the bag filling completion station are arranged vertically, with the linear drive element 6 driving the filling body in a vertical direction. This application utilizes the linear drive element 6 to drive the filling body up and down, achieving reciprocating motion between the bag receiving station and the bag filling completion station, facilitating layout and reducing occupied horizontal area. Of course, the bag receiving station and the bag filling completion station can also be arranged side by side, with the linear drive element 6 driving the horizontal direction; or the line connecting the bag receiving station and the bag filling completion station can be tilted relative to the horizontal direction.

[0046] To ensure accurate and controllable lifting and lowering positions, the conveying mechanism also includes a limiter 8 that limits the lowering position of the driving end of the linear drive member 6. The limiter 8 is provided on the frame 1 and is located below the connecting bracket 7, and can abut against the bottom of the connecting bracket 7. The limiter 8 can be a limiter plate, a limiter column, etc. Accordingly, the bottom end of the connecting bracket 7 is provided with a limiter hole that can cooperate with the limiter 8, thereby achieving a better limiting effect.

[0047] Of course, the limiting member 8 is not limited to the above-mentioned form, and other limiting methods such as front push and rear pull can also be used, which should be considered as the scope of protection of the present invention. The present invention can also control the lowering position by controlling the driving stroke of the linear drive member 6 without the above-mentioned limiting member 8.

[0048] To further optimize the above technical solution, the insertion and removal direction of the filling head 4 is angled with the vertical direction. Accordingly, the axis of the flexible bag's hose 10 is aligned with the insertion and removal direction of the filling head 4. Therefore, during transportation and filling, the hose 10 is tilted relative to the vertical direction. This reduces the vertical force exerted on the flexible bag during filling, thereby reducing the risk of the flexible bag falling and avoiding interference with the bag transfer fixture 2 and the filling fixture 9. Of course, the above insertion and removal direction can also be aligned with other directions, allowing the flexible bag's hose 10 to be placed in other orientations, such as horizontally or vertically, and this is not specifically limited by the present invention.

[0049] Specifically, the linear drive member 6 is a lifting cylinder, and the plug-in drive member 5 is a plug-in cylinder. The lifting cylinder is fixed to the frame 1, and its output end is connected to the plug-in cylinder through a connecting bracket 7, and the output end of the plug-in cylinder is connected to the filling head 4 through a connecting member.

[0050] When the equipment is in operation, the bag transfer fixture 2, holding the flexible bag hose 10, moves to a position opposite the bag receiving station. At this point, the pneumatic cylinder actuates, pushing the output end out. Driven by this, the filling head 4 is inserted into the hose 10. The hose clamping assembly 3 actuates, tightening the hose 10 onto the filling head 4. The bag transfer fixture 2 opens, releasing the hose 10. Filling now begins, with the liquid medicine passing through the filling head 4 and entering the flexible bag. Simultaneously, the filling clamp 9 opens. The lifting cylinder actuates, pushing the output end out, bringing the entire structure downward. The flexible bag enclosed in the filling head 4 moves from the bag transfer fixture 2 to the filling clamp 9, and the bag transfer fixture 2 enters the next cycle. During this process, the pneumatic cylinder remains in the pushing position, allowing the liquid medicine to continue filling. After a certain period of time, filling is complete, and the filling clamp 9 closes. The hose clamping assembly 3 actuates, releasing the hose 10. The pneumatic cylinder actuates, retracting the output end. Then, the lifting cylinder actuates, retracting the output end. After the output end of the plug-in cylinder is retracted, the soft bag can move to the subsequent process along with the filling fixture 9, and the various parts of the filling station then enter the next cycle.

[0051] The present invention utilizes a lifting cylinder to drive the filling body to move up and down between the bag receiving position and the bag filling completion position, and utilizes an insertion / extraction cylinder to drive the filling head 4 to insert or remove the hose 10. The cylinder structure is simple and cost-effective, and the lifting cylinder's short stroke shortens the filling body's cycle time, thereby improving work efficiency. The aforementioned linear drive element 6 and the insertion / extraction drive element 5 may also be other components capable of providing linear motion, such as hydraulic cylinders, servo motors, magnetically suspended linear motors, electric push rods, and the like, which are also considered within the scope of protection of the present invention.

[0052] An embodiment of the present invention also discloses a soft bag large infusion bag making and filling machine, comprising a filling device; a first conveying device for conveying the soft bags output by the bag making machine to the bag receiving position of the filling device, the first conveying device being provided with a bag transfer clamp 2 with a hose 10 that can clamp and release the soft bag; a second conveying device for conveying the soft bags at the bag filling completion position of the filling device to the next process, the second conveying device being provided with a filling clamp 9 that can clamp and release the hose 10; the filling device is the filling device provided by any of the above embodiments, which improves the filling efficiency and thereby improves the production speed of the soft bag large infusion products. The advantages are brought by the filling device. For details, please refer to the relevant parts in the above embodiments and will not be repeated here.

[0053] It should be noted that both the bag transfer clamp 2 and the filling clamp 9 are equipped with a clamp opening assembly that can open the clamp to release the hose 10; the clamp opening assembly cooperates with the action of the filling head 4 to control the opening and closing of the clamp, and as the clamp moves under the driving force of the conveying device, the clamp is opened at the position where the soft bag needs to be released.

[0054] In a specific embodiment, the first conveying device includes a first slide rail arranged on the first conveying surface of the frame 1, and the bag transfer fixture 2 slides with the first slide rail through the first slider; the second conveying device includes a second slide rail arranged on the second conveying surface of the frame 1, and the potting fixture 9 slides with the second slide rail through the second slider; wherein, there is a conveying gap between the first conveying surface and the second conveying surface for conveying soft bags.

[0055] In this embodiment, the first conveying device drives the bag transfer fixture 2 to slide along the first slide rail to convey the soft bags output by the bag making machine to the bag receiving position of the filling device. The second conveying device drives the filling and sealing fixture 9 to slide along the second slide rail to convey the soft bags at the bag filling completion position of the filling device to the next process. The first and second conveying devices can be powered by motors, cylinders, or electric push rods. The cooperation between the slide rails and the sliders ensures smooth operation, a relatively compact structure, and a small footprint. Of course, the first and second conveying devices can also adopt other structures, such as chain drive mechanisms or belt drive mechanisms.

[0056] To further optimize the above technical solution, the first and second conveying surfaces are parallel and angled with the horizontal direction, thereby ensuring that the first and second conveying devices can be separated into two parts, saving floor space and avoiding interference. The first and second conveying surfaces can also be arranged horizontally or non-parallel to each other, thereby saving floor space and avoiding interference. The first and second conveying surfaces can also be arranged horizontally or non-parallel to each other, thereby ensuring that the first and second conveying devices can be separated into two parts, saving floor space and avoiding interference. The first and second conveying surfaces can also be arranged horizontally or non-parallel to each other, thereby ensuring that the first and second conveying surfaces can be arranged horizontally or non-parallel to each other, thereby ensuring that the first and second conveying surfaces can be parallel ...

[0057] like Figure 1-3 As shown, the first and second slide rails are parallel and perpendicular to the working plane formed by the conveying axis of the conveyor mechanism and the insertion and extraction axis of the plug-in drive 5. This allows the first and second conveyor mechanisms, located on either side of the filling head 4, to respectively drive the movement of the bag transfer fixture 2 in a direction perpendicular to the working plane, further compacting the movement space and saving space. Of course, the first and second slide rails can also be arranged at an angle.

[0058] While the present invention does not explicitly describe the specific structures and operating principles of the bag transfer fixture 2, potting fixture 9, and their respective opening and closing assemblies, any hose 10 clamp with similar functionality should be considered within the scope of this invention. Implementations of the clamping assembly 3 include, but are not limited to, opening and closing grips and designs with a gradually changing inner diameter. Furthermore, adding relative motion between the bag transfer fixture 2 and potting fixture 9 to the present invention should be considered within the scope of this invention.

[0059] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0060] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
