Description

Technical Field

[0001] The present invention relates to the technical field of material feeding equipment, and in particular to an automatic material feeding method. Background Art

[0002] Currently, loading of flexible linear materials such as infusion pumps is usually done manually. This method is not only inefficient, but also easily contaminated by pathogens, requiring disinfection of operators, and high cost. After searching, Chinese patent CN103057946B discloses an infusion tube loading mechanism, which is arranged on an infusion tube assembly line and is used to realize automatic loading of infusion tube raw material tube bodies. The mechanism includes a loading assembly for loading the infusion tube body and a conveying assembly for grabbing the infusion tube body on the loading assembly and conveying it to the next process station. The invention is characterized in that the loading assembly includes a movable feeding rack, on which a plurality of grooves for accommodating the infusion tube body are provided, which are used to load the infusion tube body and move it to the bottom of the conveying assembly; the conveying assembly includes a movable bracket, a plurality of air claws are installed at the lower end of which are used to grab the infusion tube body on the movable feeding rack; the air claws with the infusion tube body are driven by the movable bracket to move and transport it to the next process station, thereby realizing automatic loading. The shortcomings of the above patent are: first, the above feeding rack places the infusion tube by setting the groove, and the infusion tube The liquid tubes need to be put on one by one, which is very troublesome. Moreover, if there are too few grooves, the feeding amount is small at a time, and it is necessary to keep going back and forth. If there are too many grooves, the feeding rack will be very large, which takes up a lot of space. Secondly, combined with the drawings of the patent, it can be seen that the two ends of the infusion tube are placed in the grooves of the feeding rack, and the middle part hangs down. Because the material of the infusion tube itself is relatively soft, and the middle part of the infusion tube is in a free hanging state, when the air claw sucks the infusion tube, it is affected by the suction force, and the naturally hanging infusion tube may shake and swing back and forth, resulting in the inability to suck. Third, in the above patent, both ends of the infusion tube are placed in the groove of the feeding rack, and there are usually connecting tubes, drip bucket components, flow regulators, intravenous needles and other components at both ends of the infusion tube, which makes the weight of the two ends of the infusion tube greater than the weight in the middle. This makes it easy for the air gripper to drop the middle of the infusion tube due to the heavier ends; Fourth, after multiple infusion tubes are clamped, the ends are often not aligned, and manual re-alignment is required, which increases the work intensity; Fifth, during the transmission of multiple infusion tubes, the distance between adjacent infusion tubes is fixed, which cannot meet the needs of spacing adjustment.

[0021] The automatic material feeding method of the above-mentioned automatic material feeding device comprises the following steps: the material is an infusion device,

[0022] The first step is to place the infusion pumps on the loading rack between the two limit baffles in front and behind the feeding plate;

[0023] The second step is feeding: start the mobile driving cylinder, the telescopic rod of the mobile driving cylinder extends, the feeding plate and the limit baffle rise, the height of the lower end of the feeding plate is higher than the height of the loading rack, the middle of the infusion set is lifted by the feeding plate, the infusion set is placed on the feeding plate, the limit baffles before and after the feeding plate block the front and rear ends of the infusion set, start the mobile feeding motor, the feeding plate carrying the infusion set moves backward under the action of the auxiliary mobile plate and the front and rear limit baffles. After the infusion set is delivered to the position, turn off the mobile feeding motor, start the mobile driving cylinder, the telescopic rod of the mobile driving cylinder retracts, the feeding plate and the limit baffle descend, the height of the feeding plate is lower than the loading rack, the infusion set falls on the loading rack, the telescopic rod of the mobile driving cylinder continues to retract, the height of the upper end of the limit baffle is lower than the height of the loading rack, turn off the mobile driving cylinder, start the mobile feeding motor, drive the feeding plate and the auxiliary mobile plate to move forward, return to their original position, and turn off the mobile feeding motor;

[0024] The third step is ejection: start the ejection front and rear drive motors to drive the material ejection mechanism forward so that the ejection tube is located under the infusion pump, start the ejection drive cylinder, retract the telescopic rod of the ejection drive cylinder, and start the power source at the same time. The power source is an air pump, and the suction groove of the ejection tube continuously inhales air. When the feed tube of the infusion pump is sucked by the suction groove, the pressure sensor detects that there is a negative pressure in the ejection tube, indicating that there is an infusion pump in the suction groove, and drives the ejection drive cylinder. The telescopic rod of the ejection drive cylinder extends, and the ejection tube moves upward. The upper end of the ejection tube presses against the infusion pump to a height higher than the remaining material on the carrier;

[0025] Step 4: Picking up the material: Simultaneously start the claw cylinders of the two claw parts on the left and right sides of the support frame to drive the first picking claw and the second picking claw to separate, that is, the picking adjustment claw is in the open state, start the claw drive moving mechanism, drive the two claw parts on the left and right sides of the support frame to move downward to the left and right sides of the ejector tube, and the infusion tube of the infusion set enters the movable limit groove of the picking adjustment claw, start the claw cylinder, close the picking adjustment claw, and complete the picking up of the infusion set. The picking adjustment claw can slide left and right along the infusion tube of the infusion set through the movable limit groove, start the claw drive moving mechanism, and the picking adjustment claw will rise with the infusion set. At the same time, start the pressing mechanism to press The material is vertically driven by the cylinder, and the telescopic rod of the vertical driving cylinder for pressing the material is extended, driving the pressing rod to move upward, and the height of the pressing rod is higher than the material carrier. Then the front and rear driving cylinders for pressing the material are started, so that the pressing rod moves forward and is placed above the remaining materials that have not been picked up. Then the vertical driving cylinder for pressing the material is started, and the telescopic rod of the vertical driving cylinder for pressing the material is retracted, driving the pressing rod to move downward, pressing the material, so that the two ends of the remaining materials are separated from the picked up materials. At the same time of pressing the material, the two shaking driving cylinders on the left and right sides of the material carrier are started, and the telescopic rods of the shaking driving cylinders are extended and retracted, retracted and extended again, so that the shaking rods shake back and forth left and right, shaking off the lower end of the remaining materials to avoid tangling.

[0026] Step 5: Straighten the material: Start the clamping claw drive moving mechanism to drive the clamping claw brackets on the left and right sides of the support frame to move left and right, and the left and right picking adjustment claws of the infusion pump slide left and right along the infusion pump and separate. At the same time, start the push plate drive cylinder, and the telescopic rod of the push plate drive cylinder extends to drive the push plate to move toward the picking adjustment claw. The picking adjustment claw on the left side of the infusion pump abuts against the push plate to fix the left end position of the infusion pump, and the picking adjustment claw on the right side of the infusion pump abuts against the push plate to fix the right end position of the infusion pump. As the picking adjustment claw on the left moves to the left and the picking adjustment claw on the right moves to the right, the loose part in the middle of the infusion pump is straightened, and then the push plate drive cylinder is started, and the telescopic rod of the push plate drive cylinder retracts to complete the material straightening operation;

[0027] Step 6: Material alignment: A connecting tube is fixed to the left end of the infusion tube of the infusion set. The outer diameter of the connecting tube is larger than the inner diameter of the movable limiting groove. After the infusion set is picked up, as the left picking adjustment claw of the infusion set moves to the left, the right picking adjustment claw moves to the right. When the left picking adjustment claw touches the connecting tube of the infusion set, the left picking adjustment claw and the connecting tube are abutted, and the position remains unchanged. The right picking adjustment claw still slides to the right along the infusion tube of the infusion set. As the left picking adjustment claw and the right picking adjustment claw continue to separate, all the picking adjustment claws on the left clamping claw bracket abut against the connecting tubes of the infusion sets they have picked up, thereby achieving alignment of the left ends of all the picked infusion sets.

[0028] Step 7: Clamping and changing distance: After the infusion set is aligned, start the clamping claw drive moving mechanism to drive the two clamping claw brackets on the left and right sides of the support frame to move upward and backward, then stop, start the variable distance drive moving mechanism, drive the two variable distance clamping parts on the left and right sides of the support frame to move downward and forward, and at the same time start the variable distance drive cylinder, the telescopic rod of the variable distance drive cylinder retracts, and at the same time start the variable distance clamping claw cylinders on the two variable distance brackets on both sides of the support frame, so that the clamping claws of the variable distance clamping claw cylinders are separated. The variable distance clamping claw cylinders on the two variable distance brackets on both sides of the support frame are located just above the infusion set clamped by the two clamping claw parts, and start The variable pitch drive mechanism drives the variable pitch clamping claw cylinders on the two variable pitch brackets to move downward, so that the infusion set is placed in the clamping claws of the variable pitch clamping claw cylinder. Then the variable pitch clamping claw cylinder is started to close the clamping claws of the variable pitch clamping claw cylinder to clamp the infusion set. The variable pitch drive mechanism is started to drive the two variable pitch brackets on the left and right sides of the support frame to move backward. At the same time, the variable pitch drive cylinder is started to increase the distance between adjacent variable pitch clamping claw cylinders. The variable pitch drive mechanism is started to drive the two variable pitch brackets on the left and right sides of the support frame to move downward and place them on the specified position of the material, thus completing the loading.

[0029] Step 8: Gather the remaining materials: Start the vertical drive cylinder for gathering, and the telescopic rod of the vertical drive cylinder extends to drive the gathering plate to rise. The upper end of the gathering plate is higher than the height of the carrier. Then start the front and rear drive cylinders for gathering, and the telescopic rods of the front and rear drive cylinders extend to move the gathering plate backward. The gathering plate cooperates with the gathering baffle to gather the materials.

[0030] Step 8: Repeat steps 3 to 8. When the quantity of materials on the carrier is lower than the set quantity, repeat steps 1 to 8 until the material loading quantity requirement is met.

[0031] Due to the adoption of the above structure, the present invention has the advantages of high material conveying efficiency, material ejection, stable material clamping, automatic material alignment, and variable spacing between materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] When in use, the material in this embodiment is described as an infusion set, but the material can also be other flexible linear materials.

[0065] The automatic material feeding method of the above-mentioned automatic material feeding device includes the following steps:

[0066] The first step is to place the infusion pumps on the loading rack 13 between the two limit baffles 17 before and after the feeding plate 16, as shown in the attached figure. Figure 3 As shown, attached Figure 3 As an example, an infusion set is placed on the carrier 13, and both ends of the infusion set naturally hang down on both sides of the carrier 13;

[0067] The second step is feeding: start the mobile drive cylinder 15, the telescopic rod of the mobile drive cylinder 15 extends, the feeding plate 16 and the limit baffle 17 rise, the height of the lower end of the feeding plate 16 is higher than the height of the carrier 13, the middle part of the infusion set is lifted by the feeding plate 16, the infusion set is placed on the feeding plate 16, the limit baffles 17 before and after the feeding plate 16 block the front and rear ends of the infusion set, start the mobile feeding motor 20, the feeding plate 16 carrying the infusion set moves backward under the action of the auxiliary moving plate 19 and the front and rear limit baffles 17. After the infusion set is delivered to the position, The mobile feeding motor 20 is turned off, and the mobile driving cylinder 15 is started. The telescopic rod of the mobile driving cylinder 15 is retracted, and the feeding plate 16 and the limit baffle 17 are lowered. The height of the feeding plate 16 is lower than the carrier 13, and the infusion set falls onto the carrier 13. The telescopic rod of the mobile driving cylinder 15 continues to retract, and the height of the upper end of the limit baffle 17 is lower than the height of the carrier 13. The mobile driving cylinder 15 is turned off, and the mobile feeding motor 20 is started, driving the feeding plate 16 and the auxiliary mobile plate 19 to move forward and return to their original position, and the mobile feeding motor 20 is turned off;

[0068] The third step is ejecting the material: start the ejection front and rear drive motors 22 to drive the material ejection mechanism 11 to move forward, so that the ejection tube 5 is located below the infusion pump, start the ejection drive cylinder 3, and retract the telescopic rod of the ejection drive cylinder 3. At the same time, start the air pump, and the suction groove 6 of the ejection tube 5 continuously inhales air. When the feed pipe of the infusion pump is sucked by the suction groove 6, the pressure sensor detects that there is a negative pressure in the ejection tube 5. It can be seen that there is an infusion pump in the suction groove 6, and the ejection drive cylinder 3 is driven. The telescopic rod of the ejection drive cylinder 3 is extended, and the ejection tube 5 moves upward. The upper end of the ejection tube 5 pushes against the infusion pump and is higher than the height of the remaining material on the carrier 13;

[0069] Step 4: Picking up the material: Simultaneously start the clamping cylinders 41 of the two clamping claw components 36 on the left and right sides of the support frame 37, drive the first picking claw 44 and the second picking claw 45 to separate, that is, the picking adjustment claw 46 is in the open state, start the clamping claw driving moving mechanism 38, drive the two clamping claw components 36 on the left and right sides of the support frame 37 to move downward to the left and right sides of the ejection tube 5, the picking adjustment claw 46 is opened, and the infusion tube of the infusion set enters the movable limiting groove 48 of the picking adjustment claw 46, start the clamping claw cylinder 41, close the picking adjustment claw 46, and complete the picking up of the infusion set. The picking adjustment claw 46 can slide left and right along the infusion tube of the infusion set through the movable limiting groove 48, start the clamping claw driving moving mechanism 38, and the picking adjustment claw 46 rises with the infusion set. At the same time, start the material pressing mechanism 29. Start the material pressing vertical drive cylinder 31, and the telescopic rod of the material pressing vertical drive cylinder 31 extends, driving the material pressing rod 30 to move upward, and the height of the material pressing rod 30 is higher than the material carrier 13. Then start the material pressing front and rear drive cylinders 32, so that the material pressing rod 30 moves forward and is placed above the remaining materials that have not been picked up. Then start the material pressing vertical drive cylinder 31, and the telescopic rod of the material pressing vertical drive cylinder 31 retracts, driving the material pressing rod 30 to move downward, pressing the materials, so that the two ends of the remaining materials are separated from the picked materials. At the same time of pressing the materials, start the material shaking mechanism 33, and start the two material shaking drive cylinders 35 on the left and right sides of the material carrier 13. The telescopic rod of the material shaking drive cylinder 35 extends and retracts, retracts and then extends, so that the material shaking rod 34 shakes back and forth left and right, shaking off the lower end of the remaining materials to avoid tangling.

[0070] Step 5: Straightening the material: Start the clamping claw drive moving mechanism 38, drive the clamping claw brackets 40 on the left and right sides of the support frame 37 to move left and right, and the left and right picking adjustment claws 46 of the infusion set slide left and right along the infusion set and separate. At the same time, start the push plate drive cylinder 50, and the telescopic rod of the push plate drive cylinder 50 extends, driving the push plate 51 to move toward the picking adjustment claw 46. The picking adjustment claw 46 on the left side of the infusion set abuts against the push plate 51 to fix the left end position of the infusion set, and the picking adjustment claw 46 on the right side of the infusion set abuts against the push plate 51 to fix the right end position of the infusion set. As the picking adjustment claw 46 on the left side moves to the left and the picking adjustment claw 46 on the right side moves to the right, the loose part in the middle of the infusion set is straightened, and then the push plate drive cylinder 50 is started, and the telescopic rod of the push plate drive cylinder 50 retracts to complete the material straightening operation.

[0071] Step 6: Material alignment: A connecting tube is fixedly provided at the left end of the infusion tube of the infusion set, and the outer diameter of the connecting tube is larger than the inner diameter of the movable limiting groove 48. In this way, when the infusion set rises after being picked up, as the left picking adjustment claw 46 of the infusion set moves to the left, the right picking adjustment claw 46 moves to the right. When the left picking adjustment claw 46 hits the connecting tube of the infusion set, as the left picking adjustment claw 46 moves to the left, the left picking adjustment claw 46 abuts against the connecting tube, and the position remains unchanged. The right picking adjustment claw 46 still slides to the right along the infusion tube of the infusion set. As the left picking adjustment claw 46 and the right picking adjustment claw 46 continue to separate, all the picking adjustment claws 46 on the left clamping claw bracket 40 abut against the connecting tube of the infusion set they have picked up, thereby achieving alignment of the left ends of all the picked infusion sets.

[0072] Step 7: Clamping and changing distance: After the infusion set is aligned, start the clamping claw driving moving mechanism 38 to drive the two clamping claw brackets 40 on the left and right sides of the support frame 37 to move upward and backward, then stop, start the variable distance driving moving mechanism 60, drive the two variable distance clamping components 59 on the left and right sides of the support frame 37 to move downward and forward, and at the same time start the variable distance driving cylinder 62, the telescopic rod of the variable distance driving cylinder 62 retracts, and the distance between adjacent variable distance clamping claw cylinders 62 becomes minimum, and at the same time start the variable distance clamping claw cylinders 62 on the two variable distance brackets 61 on both sides of the support frame 37, so that the clamping claws of the variable distance clamping claw cylinders 62 are separated, and the variable distance clamping claw cylinders 62 on the two variable distance brackets 61 on both sides of the support frame 37 are located at the two clamping claw components 36 Just above the clamped infusion set, the variable pitch drive moving mechanism 60 is started, driving the variable pitch clamping claw cylinders 62 on the two variable pitch brackets 61 to move downward, so that the infusion set is placed in the clamping claws of the variable pitch clamping claw cylinders 62, and then the variable pitch clamping claw cylinders 62 are started to close the clamping claws of the variable pitch clamping claw cylinders 62 to clamp the infusion set, and the variable pitch drive moving mechanism 60 is started to drive the two variable pitch brackets 61 on the left and right sides of the support frame 37 to move backward, and at the same time, the variable pitch drive cylinders 62 are started to increase the distance between adjacent variable pitch clamping claw cylinders 62, and the variable pitch drive moving mechanism 60 is started to drive the two variable pitch brackets 61 on the left and right sides of the support frame 37 to move downward and place them on the specified position of the material to complete the loading;

[0073] Step 8: Gathering the remaining materials: Start the vertical gathering drive cylinder 26, the telescopic rod of the vertical gathering drive cylinder 26 extends, driving the gathering plate 24 to rise, and the upper end of the gathering plate 24 is higher than the height of the carrier 13, then start the front and rear gathering drive cylinders 25, the telescopic rod of the front and rear gathering drive cylinders 25 extends, and the gathering plate 24 moves backward, and the gathering plate 24 cooperates with the gathering baffle 27 to gather the materials;

[0074] Step 9: Repeat steps 3 to 8. When the amount of material on the carrier 13 is lower than the set amount, repeat steps 1 to 8 until the material loading quantity requirement is met; repeat this process to achieve automatic loading. The amount of remaining material on the carrier 13 can be determined based on the amount of material fed out at one time in the second step and the frequency of ejecting material in the third step. This can be done through the control system, or the operator can adjust the program in the control system in time after on-site inspection and set it according to demand. Compared with the prior art, the present invention has a clever structure and is easy to operate. It can transport a lot of materials at a time and does not need to be placed one by one, saving time and effort. Before the material is clamped, it can be sucked out and then ejected to ensure accurate clamping and prevent it from falling. In addition, the infusion set of the present invention can be automatically aligned and automatically straightened. At the same time, the infusion set after loading can adjust the distance between adjacent infusion sets as needed to meet the need for adjusting the material spacing.

[0075] Due to the adoption of the above structure, the present invention has the advantages of high material conveying efficiency, material ejection, stable material clamping, automatic material alignment, and variable spacing between materials.
