Technical Field

[0001] The present invention relates to the technical field of automatic packaging of infusion sets, and in particular to a flow regulator position adjustment device for an infusion set product. Background Art

[0002] A disposable infusion set is a common medical consumable used for intravenous infusion. It typically consists of an IV needle, a needle holder, an infusion hose, a liquid filter, a flow regulator, a drip chamber, a bottle puncture device, an endotracheal tube, and an air filter. Disposable infusion sets are relatively long. The flow regulator consists of a housing and a roller connected to the housing. The housing has a channel for the hose to pass through. The structure of the flow regulator is in accordance with the national standard GBT43277.1-2023.

[0003] Regarding the production process of disposable infusion sets, the packaging process of the finished disposable infusion sets is completed by automatic packaging equipment. The basic operation sequence of the automatic packaging process is: (1) loading, (2) placing the infusion set in a straight line, (3) transferring the infusion set in a straight line to the winding device position, (4) the winding device operates to wind the infusion set in a straight line into a roll, and (5) placing the rolled infusion set into a packaging bag. The specific structure of the existing automatic packaging equipment can be referred to the invention patent application with application publication number CN111348279A, entitled Automatic Material Picking, Winding and Bagging Device for Infusion Sets.

[0055] The application will be further described in detail below with reference to the accompanying drawings using specific embodiments.

[0056] The specific embodiments described below are merely preferred embodiments of the present application, and the scope of protection of the present application is not limited thereto. Those skilled in the art may make some modifications or variations based on or in accordance with the principles, concepts, and spirit of the present application, and the technical solutions formed by such modifications or variations shall be included within the scope of protection of the present application.

[0057] like Figure 1-7 As shown, the flow regulator position adjustment device includes a loading device 100, an X-axis linear module 200, a Y-axis linear module 300, a first Z-axis linear module 400, a second Z-axis linear module 500, a first clamping mechanism 600, a second clamping mechanism 700, a third clamping mechanism 800, and a third Z-axis linear module 900. The Y-axis linear module 300 is installed on the frame, the X-axis linear module 200 is connected to the Y-axis linear module 300, and the first Z-axis linear module 400 is connected to the X-axis linear module 200. The second Z-axis linear module 500 is connected to the X-axis linear module 200, the third Z-axis linear module 900 is connected to the X-axis linear module 200, and the third Z-axis linear module 900 is located on the right side of the second Z-axis linear module 500; the first clamping mechanism 600 is connected to the first Z-axis linear module 400, the second clamping mechanism 700 is connected to the second Z-axis linear module 500, and the third clamping mechanism 800 is connected to the third Z-axis linear module 900; the third clamping mechanism 800 is located on the right side of the second clamping mechanism 700. The Y-axis linear module 300 drives the entire X-axis linear module 200 along the Y-axis, thereby causing the first, second, and third clamping mechanisms 600, 700, and 800 to move along the Y-axis. The X-axis linear module 200 drives the first, second, and third Z-axis linear modules 400, 500, and 900 along the X-axis, thereby causing the first, second, and third Z-axis linear modules 600, 700, and 800 to move along the X-axis. The first Z-axis linear module 400 drives the first clamping mechanism 600 along the Z-axis, the second Z-axis linear module 500 drives the second clamping mechanism 700 along the Z-axis, and the third Z-axis linear module 900 drives the third clamping mechanism 800 along the Z-axis. The loading device 100 is located below the X-axis linear module 200.

[0058] like Figure 1 、 2As shown in Figures 3, 8 and 9, the first clamping mechanism 600 includes a first bracket 601, a first driving unit 602, and a first clamping jaw 603. The first driving unit 602 is installed on the first bracket 601, and the first clamping jaw 603 is connected to the first driving unit 602. The first driving unit 602 can close or open the first clamping jaw 603. The first clamping jaw 603 includes a clamping portion 1 603-1 and a clamping portion 2 603-2. A recess 603-1-1 is provided on the inner side of the clamping portion 1 603-1, and a lifting portion 603-1-2 is provided at the lower end of the clamping portion 1 603-1. A recess 603-2-1 is provided on the inner side of the clamping portion 2 603-2, and a lifting portion 603-2-2 is provided at the lower end of the clamping portion 2 603-2. When the clamping portion 1 603-1 and the clamping portion 2 603-2 are closed, the recess 603-1-1 and the recess 603-2-1 form a accommodating space, and the hose of the infusion pump can move in the accommodating space. The lifting portion 603-1-2 and the lifting portion 603-2-2 are connected together to lift the hose upward to prevent the hose from falling out of the clamping jaw. The number of the first gripper 603 is at least one. The figure shows that a plurality of first grippers 603 are arranged in a line. When a plurality of first grippers are provided, as shown in the figure, the first driving unit 602 specifically includes a first driving module, a rear sliding plate 602-1, a front sliding plate 602-2, and a guide rail assembly 602-3. The first driving module usually selects a finger cylinder or an electric finger. The rear sliding plate 602-1 and the front sliding plate 602-2 are respectively connected to the two fingers of the finger cylinder (or electric finger). The guide rail Component 602-3 is connected between the rear sliding plate 602-1 and the front sliding plate 602-2. The clamping part 1 603-1 of each first clamping jaw 603 is connected to the front sliding plate 602-2, and the clamping part 2 603-2 of each first clamping jaw 603 is connected to the rear sliding plate 602-1. When the finger cylinder (or electric finger) is actuated, the rear sliding plate 602-1 and the front sliding plate 602-2 can slide relative to each other, and then the rear sliding plate 602-1 and the front sliding plate 602-2 drive each clamping jaw to close or open. Figure 9 One of the advantages of arranging multiple first clamps 603 in the above manner is that the distance between two adjacent first clamps is small, so that when operating multiple infusion products, the distance between two adjacent infusion products can be kept small.

[0059] If only one first clamping jaw 603 is provided, the rear sliding plate 602-1, the front sliding plate 602-2 and the guide rail assembly 602-3 may not be used, and the clamping part 1 603-1 and the clamping part 2 603-2 of the first clamping jaw 603 may be directly connected to the two fingers of the finger cylinder (or electric finger).

[0060] The first bracket 601 is mounted on the slider of the first Z-axis linear module 400 .

[0061] like Figure 1 、 2 As shown in Figures 3, 8 and 10, the second clamping mechanism 700 includes a second bracket 701, a second driving unit 702, and a second clamping jaw 703. The second driving unit 702 is installed on the second bracket 701, and the second clamping jaw 703 is connected to the second driving unit 702. The second driving unit 702 can close or open the first clamping jaw 603. The second clamping jaw 703 includes a clamping portion 1 703-1 and a clamping portion 2 703-2. A recess 703-1-1 is provided on the inner side of the clamping portion 1 703-1, and a lifting portion 703-1-2 is provided at the lower end of the clamping portion 1 703-1. A recess 703-2-1 is provided on the inner side of the clamping portion 2 703-2, and a lifting portion 703-2-2 is provided at the lower end of the clamping portion 2 703-2. When the clamping portion 1 703-1 and the clamping portion 2 703-2 are closed, the recess 703-1-1 and the recess 703-2-1 form a accommodating space, and the hose of the infusion pump can move in the accommodating space. The lifting portion 703-1-2 and the lifting portion 703-2-2 are docked together to lift the hose upward to prevent the hose from falling out of the clamping jaw. The number of the second clamping jaws 703 is at least one. The figure shows that a plurality of second clamping jaws 703 arranged in a line are provided. When a plurality of second clamping jaws are provided, the specific structure is basically the same as the structure of the plurality of first clamping jaws provided in the above-mentioned first clamping mechanism 600, that is, the second driving unit 702 includes a second driving module, a rear sliding plate, a front sliding plate, and a guide rail assembly. The second driving module usually selects a finger cylinder or an electric finger. The rear sliding plate and the front sliding plate are respectively connected to the two fingers of the finger cylinder (or electric finger). The guide rail assembly is connected between the rear sliding plate and the front sliding plate. The clamping part 1 of each second clamping jaw is connected to the front sliding plate, and the clamping part 2 of each second clamping jaw is connected to the rear sliding plate. Figure 10 If only one second clamping jaw 703 is provided, the rear sliding plate, front sliding plate and guide rail assembly can be omitted, and the clamping portion 1 703-1 and the clamping portion 2 703-2 of the second clamping jaw 703 can be directly connected to the two fingers of the finger cylinder (or electric finger).

[0062] The second bracket 701 is mounted on the slider of the second Z-axis linear module 500 .

[0063] like Figure 1 、 3As shown in Figures 7 and 11, the third clamping mechanism 800 includes a third bracket 801, a translation module 802, a third drive unit 803, and a third clamping jaw 804. The translation module 802 is connected to the third bracket 801, the third drive unit 803 is connected to the third bracket 801, and the third clamping jaw 804 is connected to the third drive unit 803. The third drive unit 803 is used to open or close the third clamping jaw 804. The third clamping jaw 804 includes a first clamping portion 804-1 and a second clamping portion 804-2. A recess 804-1-1 is provided on the inner side of the first clamping portion 804-1, and a supporting portion 804-1-2 is provided at the lower end of the first clamping portion 804-1. A recess 804-2-1 is provided on the inner side of the second clamping portion 804-2, and a supporting portion 804-2-2 is provided at the lower end of the second clamping portion 804-2. When the first clamping portion 804-1 and the second clamping portion 804-2 are closed, the recess 804-1-1 and the recess 804-2-1 form a accommodating space, and the hose of the infusion pump can move in the accommodating space. The supporting portion 804-1-2 and the supporting portion 804-2-2 are docked together to lift the hose upward to prevent the hose from falling out of the clamping jaw. The translation module 802 (which may be a cylinder) moves to make the third driving unit 803 translate along the X direction, thereby making the third clamping jaw 804 translate along the X direction. The number of the third clamping jaws 804 is at least one. The figure shows that a plurality of third clamping jaws 804 are arranged in a line. When a plurality of third clamping jaws are provided, as shown in the figure, the third driving unit 803 specifically includes a third driving module, a front skateboard 803-1, a rear skateboard 803-2, and a guide rail assembly. The third driving module usually selects a finger cylinder or an electric finger. The front skateboard 803-1 and the rear skateboard 803-2 are respectively connected to the two fingers of the finger cylinder (or electric finger). The guide rail assembly is connected between the front skateboard 803-1 and the rear skateboard 803-2. The first clamping part 804-1 of each third clamping jaw 804 is connected to the rear skateboard 803-2, and the second clamping part 804-2 of each third clamping jaw 804 is connected to the front skateboard 803-1. When the finger cylinder (or electric finger) is actuated, the rear skateboard 803-2 and the front skateboard 803-1 can slide relative to each other, and then the rear skateboard 803-2 and the front skateboard 803-1 drive each third clamping jaw to close or open. Figure 11 One advantage of providing multiple third clamps in this manner is that the spacing between two adjacent third clamps is small, which ensures that the spacing between two adjacent infusion sets is small when operating multiple infusion sets.

[0064] If only one third clamping jaw 804 is provided, the front slide 803-1, the rear slide 803-2 and the guide rail assembly can be omitted, and the first clamping part 804-1 and the second clamping part 804-2 of the third clamping jaw 804 can be directly connected to the two fingers of the finger cylinder (or electric finger).

[0065] The third bracket 801 is mounted on the slider of the third Z-axis linear module 900 .

[0066] When multiple third clamping jaws 804 , multiple second clamping jaws 703 , and multiple first clamping jaws 603 are provided, the number of the third clamping jaws 804 , the number of the second clamping jaws 703 , and the number of the first clamping jaws 603 are equal.

[0067] The following describes the operation process of the flow regulator position adjustment device:

[0068] Step S1, reference Figure 12 and 13 , a plurality of support frames 100-1 are provided on the top of the loading device 100, and each support frame 100-1 is provided with two grooves on the front side and two grooves on the back side, and the two grooves on the front side correspond to the two grooves on the back side, that is, two infusion products can be hung on one support frame 100-1; Figure 12 and 13 It can be seen that an infusion product is hung on the grooves on the front and rear sides of the support frame 100-1, and the hose portion between the front and rear grooves can basically be located on the horizontal plane (that is, the top of the hose of the infusion product in the suspended state is basically located on the horizontal plane). The multiple support frames 100-1 of the loading device 100 are located below the first clamping mechanism 600 and the second clamping mechanism 700. Figure 12 、 13 As can be seen in the figure, the distance between the flow regulator 1-6 and the venous needle seat 1-5 in the infusion product is not fixed. In the 8 infusion products shown in the figure, the distance between the flow regulator 1-6 and the venous needle seat 1-5 is different. In addition, since the hanging position of the infusion product on the support frame 100-1 is not fixed, the positions of the eight flow regulators 1-6 in the vertical direction are disordered. However, the eight flow regulators 1-6 are all located on the right side of the support frame 100-1, and the drip bucket 1-2 is located on the left side of the support frame 100-1 (as shown in the figure). Figure 12 shown).

[0069] In step S2, the first clamping jaw 603 on the first clamping mechanism 600 is initially in the open state, and the second clamping jaw 703 on the second clamping mechanism 700 is initially in the open state. The controller issues a command, and the first Z-axis linear module 400 and the second Z-axis linear module 500 are activated to cause the first clamping mechanism 600 and the second clamping mechanism 700 to descend along the Z-axis direction. The first clamping jaw 603 and the second clamping jaw 703 in the open state descend from their initial positions to the top position of the infusion set hose, as shown in FIG. Figure 14 As shown, the top of the hose is now located between clamping portion 1 603-1 and clamping portion 2 603-2, and between clamping portion 1 703-1 and clamping portion 2 703-2. Next, the controller issues a command to simultaneously close the first and second clamping jaws 603 and 703, placing the hose within the accommodation space formed by recesses 603-1-1 and 603-2-1, and within the accommodation space formed by recesses 703-1-1 and 703-2-1. Next, the first and second Z-axis linear modules 400 and 500 operate to raise the first and second clamping mechanisms 600 and 700 to their initial positions. The first and second clamping jaws 603 and 703 then move upward with the infusion pump (the lifting portions 603-1-2 and 603-2-2 of the first clamping jaw 603 hold the hose upward), and the infusion pump is released from the support frame 100-1, completing the material removal process. At this time, the entire infusion set is still in a natural drooping state.

[0070] Step S3: straighten the infusion set so that the infusion set is in a straight line.

[0071] The controller instructs the X-axis linear module 200 to move, so that the first Z-axis linear module 400 and the second Z-axis linear module 500 move away from each other in the X-axis direction. Figure 3 , that is, the first clamping mechanism 600 moves to the left and the second clamping mechanism 700 moves to the right, that is, the first clamping jaw 603 moves to the left and the second clamping jaw 703 moves to the right. The left end point P (i.e., the stop position) of the first clamping jaw 603 moving to the left and the right end point Q (i.e., the stop position) of the second clamping jaw 703 moving to the right. The distance L between the left end point P and the right end point Q is determined according to the length of the infusion set, refer to Figure 15 and 16 When the infusion set is in a straight line state, and the small end of the flow regulator 1-6 is against the venous needle seat 1-5, in this state, the distance between the drip bucket 1-2 and the large end of the flow regulator 1-6 is the distance L.

[0072] There are three specific ways to straighten it:

[0073] (1) The first method:

[0074] The first clamping mechanism 600 and the second clamping mechanism 700 start to move at the same time. The first clamping mechanism 600 moves to the left and the second clamping mechanism 700 moves to the right. After a period of time, the first clamping jaw 603 reaches the left end point P and stops. At the same time, the second clamping jaw 703 reaches the right end point Q and stops. That is, the first clamping jaw 603 and the second clamping jaw 703 reach their respective end points at the same time. Figure 15 and 16 As shown, the first clamping jaw 603 abuts against the drip bucket 1-2, the second clamping jaw 703 abuts against the large end of the flow regulator 1-6, and the small end of the flow regulator 1-6 abuts against the venous needle seat 1-5.

[0075] (2) The second method:

[0076] The first clamping mechanism 600 and the second clamping mechanism 700 begin moving simultaneously, the first clamping mechanism 600 moving leftward and the second clamping mechanism 700 moving rightward. The second clamping jaw 703 reaches the right endpoint Q and stops first, followed by the first clamping jaw 603 reaching the left endpoint P and stopping later. At this point, the infusion set is straightened, with the first clamping jaw 603 resting against the drip funnel 1-2, the second clamping jaw 703 resting against the large end of the flow regulator 1-6, and the small end of the flow regulator 1-6 resting against the intravenous needle holder 1-5.

[0077] (3) The third method:

[0078] The first clamping mechanism 600 and the second clamping mechanism 700 start moving simultaneously, the first clamping mechanism 600 moving to the left and the second clamping mechanism 700 moving to the right. The first clamping jaw 603 reaches the left endpoint P and stops first, followed by the second clamping jaw 703 reaching the right endpoint Q and stopping later. At this point, the infusion set is straightened, with the first clamping jaw 603 resting against the drip funnel 1-2, the second clamping jaw 703 resting against the large end of the flow regulator 1-6, and the small end of the flow regulator 1-6 resting against the intravenous needle holder 1-5.

[0079] In this way, the setting can be further optimized, namely: the first clamping mechanism 600 and the second clamping mechanism 700 start moving at the same time, the first clamping mechanism 600 moves to the left, and the second clamping mechanism 700 moves to the right; next, the second clamping mechanism 700 moves a certain distance to the right and then stops (that is, the second clamping jaw 703 moves to the right to the position point S and stops moving), the first clamping jaw 603 first reaches the left end point P and stops, and then the second clamping jaw 703 continues to move to the right (that is, after the first clamping jaw 603 reaches the left end point P, the second clamping jaw 703 continues to move to the right), and then the second clamping jaw 703 reaches the right end point Q and stops.

[0080] Further optimized settings: The distance between position point S and the right end point Q is one-ninth of the distance L. The advantage of this setting is that when processing multiple infusion products arranged side by side, and when the distance between two adjacent infusion products is close, the hoses at the two adjacent infusion needle seats 1-5 will not interfere or become entangled during the process of the second clamping jaw 703 moving from position point S to the right end point Q, thereby ensuring the quality and efficiency of the operation. Further optimized settings, the speed of the second clamping jaw 703 moving from position point S to the right end point Q is V2, and the speed of the first clamping jaw 603 moving from the starting point to the left end point P is V1, and V2 is less than V1.

[0081] Step S4: Use the third clamping mechanism 800 to position the venous needle seat 1-5.

[0082] In step S401, the third clamping mechanism 800 is actuated to clamp the small end of the flow regulator 1-6. The specific action method can be: the initial state of the third clamping jaw 804 is open, the third Z-axis linear module 900 is actuated to lower the third clamping mechanism 800, and then the translation module 802 is actuated to move the third clamping jaw 804 forward, and the third clamping jaw 804 is moved to the position of the flow regulator 1-6, and the small end of the flow regulator 1-6 is located between the first clamping part 804-1 and the second clamping part 804-2; next, the third driving unit 803 is actuated to close the third clamping jaw 804, as shown in FIG. Figure 17 As shown, the small end of the flow regulator 1-6 is located in the accommodation space formed by the recess 804-1-1 and the recess 804-2-1. At this time, the small end of the flow regulator 1-6 can move in the accommodation space, and the small end of the flow regulator 1-6 is not locked.

[0083] It should be noted that the third Z-axis linear module 900 and the translation module 802 can simultaneously actuate the third clamping jaw 804 to move to the flow regulator 1-6 position.

[0084] It should be noted that regarding the action of the third clamping mechanism 800, the third clamping jaw 804 can be aligned with the flow regulator 1-6 in the horizontal direction in advance, thus eliminating the process of "the third Z-axis linear module 900 moves to lower the third clamping mechanism 800".

[0085] It should be noted that, regarding the action of the third clamping mechanism 800, the third clamping jaw 804 can be aligned with the flow regulator 1-6 in the horizontal direction in advance, and the third clamping jaw can be allowed to wait in the appropriate position, thus eliminating the need for "the third Z-axis linear module 900 to move the third clamping mechanism 800 downward" and "the translation module 802 to move the third clamping jaw 804 forward".

[0086] In step S402, the second clamping jaw 703 is opened, and then the second Z-axis linear module 500 is actuated to raise the second clamping mechanism 700 a certain distance, that is, to raise the second clamping jaw 703 a certain distance, and the second clamping jaw 703 is separated from the infusion tube. At this time, the rightward thrust of the second clamping jaw 703 disappears, and the end face of the intravenous needle seat 1-5 abuts against the end faces of the first clamping portion 804-1 and the second clamping portion 804-2, as shown in FIG. Figure 18 shown.

[0087] Step S5: Let the second clamping jaw 703 clamp the flow regulator 1-6.

[0088] The X-axis linear module 200 moves the second clamping jaw 703 a short distance to the right, positioning the second clamping jaw 703 above the flow regulator 1-6. The second Z-axis linear module 500 then moves the second clamping jaw 703 down to the position of the flow regulator 1-6. The first clamping portion 703-1 and the second clamping portion 703-2 of the second clamping jaw 703 are positioned on either side of the flow regulator 1-6.

[0089] Next, the second clamping jaw 703 is closed, and the second clamping jaw 703 clamps the flow regulator 1 - 6 , and the flow regulator 1 - 6 is tightened and cannot move relative to the second clamping jaw 703 .

[0090] In step S6, the X-axis linear module 200 is activated, causing the second Z-axis linear module 500 to move leftward in the X-axis direction, that is, the second clamping mechanism 700 moves leftward, that is, the second clamping jaw 703 moves leftward, and the second clamping jaw 703 moves the flow regulator 1-6 to the left for a certain distance and then stops. The distance is the distance between the flow regulator 1-6 and the intravenous needle seat 1-5. Figure 20 The hose at the venous needle seat 1-5 is located in the accommodation space formed by the recess 804-1-1 of the first clamping portion 804-1 of the third clamping jaw 804 and the recess 804-2-1 of the second clamping portion 804-2.

[0091] Next, the second clamping jaw 703 is opened, and then the second Z-axis linear module 500 is actuated to raise the second clamping jaw 703 so that the second clamping jaw 703 is away from the flow regulator 1-6. At this point, the position adjustment task of the flow regulator 1-6 is completed.

[0092] As can be seen, the position of flow regulator 1-6 is adjusted by adjusting it away from the venous needle holder 1-5, with the large end of flow regulator 1-6 in front and the small end in the back as it moves along the flexible tube. It should be noted that the specific distance between flow regulator 1-6 and venous needle holder 1-5 after adjustment is determined based on actual needs; flow regulator 1-6 can be closer to or farther from the venous needle holder 1-5.

[0093] Step S6: releasing the infusion set product after the flow regulator position adjustment has been completed.

[0094] The specific process can be as follows: the Y-axis linear module 300 is actuated to synchronously move the first clamping mechanism 600 and the third clamping mechanism 800 along the Y-axis, that is, the first clamping jaw 603 and the third clamping jaw 804 are synchronously moved along the Y-axis. This allows the first clamping jaw 603 and the third clamping jaw 804 to move the infusion set product, whose flow regulator has been adjusted, without causing the infusion set product to fall during movement. When the infusion set product moves to the desired position, such as above a conveyor belt or a platform, the first Z-axis linear module 400 and the third Z-axis linear module 900 are synchronously actuated to lower the first clamping mechanism 600 and the third clamping mechanism 800. The first clamping jaw 603 and the third clamping jaw 804 then descend with the infusion set. Once the infusion set product is placed on the conveyor belt or the platform, the first clamping mechanism 600 and the third clamping mechanism 800 stop moving. Next, the first clamping jaw 603 and the third clamping jaw 804 are opened. Next, the first clamping mechanism 600 and the third clamping mechanism 800 are raised, and the first clamping jaw 603 and the third clamping jaw 804 are separated from the infusion set.

[0095] Step S7 , returning the first clamping mechanism 600 , the second clamping mechanism 700 and the third clamping mechanism 800 to their initial positions, and preparing to process the next group of infusion sets on the loading device 100 .

[0096] It should be noted that, regarding Figure 12 In the suspended infusion product shown, the roller in the flow regulator 1-6 is usually located at the large end of the flow regulator 1-6 (the roller does not squeeze the hose at this time), or the roller slightly squeezes the hose. It is possible that the roller is located in the middle of the flow regulator 1-6 or in the middle close to the small end. In this case, the roller in the flow regulator 1-6 presses the hose tightly. When this happens, the process of straightening the infusion set into a straight state in step S3 can also proceed smoothly. Figure 21 When the second clamping jaw 703 moves to the right, it pushes the flow regulator 1-6 to the right. After the flow regulator 1-6 moves a short distance to the right along the hose, the roller 1-8 moves to the large end of the flow regulator 1-6 (at this time, the roller 1-8 does not squeeze the hose), ensuring that the roller 1-8 is located at the large end of the flow regulator 1-6 when the flow regulator 1-6 finally abuts the intravenous needle seat 1-5. During step 6, when the second clamping jaw 703 moves to the left while holding the flow regulator 1-6, it can ensure that the flow regulator 1-6 moves smoothly and without resistance, ensuring that the position of the flow regulator 1-6 is adjusted to the correct position.

[0097] Regarding the control system, a PLC controller can be used.

[0098] about Figure 12 The loading station shown can translate the loading device 100 in a horizontal plane through a translation device, so that the multiple support frames 100 - 1 of the loading device 100 are conveniently located below the first clamping mechanism 600 and the second clamping mechanism 700 .
