Description

Technical Field

[0001] This invention belongs to the field of medical dressing production technology, and specifically relates to an automated production method for a medical abdominal pad. Background Technology

[0002] Abdominal pads are primarily used in surgical procedures to absorb blood and exudate, isolate organs, absorb blood from wound surfaces, and clean the skin. To facilitate tracking, an X-ray tracking line is incorporated into the abdominal pad, allowing it to be tracked when X-rays are applied to the body. Abdominal pads are typically rectangular, with an X-ray tracking line (usually a folded blue barium strip running along the length of the pad) at one corner. The abdominal pads can be folded for packaging.

[0003] For example, patent application number CN202210978373.0 discloses an abdominal pad folding and binding machine, comprising: a frame; a feeding unit disposed within the frame for positioning and conveying abdominal pads; at least one straightening and folding unit connected to the feeding unit for straightening and folding the abdominal pads fed by the feeding unit; a pressing unit connected to the straightening and folding unit for pressing multiple folded abdominal pads fed by the straightening and folding unit together to form an abdominal pad group; and a receiving unit connected to the pressing unit for binding and pressing multiple abdominal pad groups fed by the pressing unit and then feeding them out in one go.

[0004] The aforementioned device has a complex folding structure and can only use a fixed folding method. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an automated production method for a medical abdominal pad. This method automates the folding and binding of the abdominal pad, featuring a simple folding structure that allows for various folding methods (vertical folding includes both bi-folding and Z-shaped folding, facilitating adjustment of the folding size). The resulting product has a good appearance. The technical solution is as follows:

[0006] This invention provides an automated production method for a medical abdominal pad, the method comprising: S1 Manual Feeding and Stretching: At the first feeding station, the abdominal pad is manually fixed to the loading plate and stretched manually or automatically; after fixing, the three-station turntable rotates.

[0007] S2 Ironing: At the ironing station, the ironing structure irons the abdominal pad; after ironing is completed, the three-station turntable rotates.

[0008] S3 workbench transfer and X-ray tracking line folding: At the first discharge station, the folding transfer structure transfers the ironed abdominal pad from the first discharge station to the second feed station; during the transfer process, the air blowing device blows the X-ray tracking line into the underside of the abdominal pad.

[0009] S4 Longitudinal Folding and Flattening: At the longitudinal folding station, either the longitudinal folding component of the bidirectional folding structure or the Z-shaped folding mechanism of the longitudinal folding and flattening structure works. The longitudinal folding component is used to fold the abdominal pad once or multiple times, and the Z-shaped folding mechanism is used to fold the abdominal pad in a Z-shape. When the longitudinal folding component folds, the longitudinal folding plate flips over. After longitudinal folding, the longitudinal folding pressure plate of the longitudinal folding and flattening structure presses the longitudinally folded abdominal pad tightly. After pressing is completed, the four-station turntable rotates.

[0010] S5 Lateral Folding and Flattening: At the lateral folding station, the lateral folding assembly of the bidirectional folding structure folds the abdominal pad after longitudinal folding laterally; during lateral folding, the two lateral folding plates of the lateral folding assembly flip in sequence; after lateral folding, the lateral folding pressure plate presses the laterally folded abdominal pad tightly; after pressing is completed, the four-station turntable rotates.

[0011] S6 Stacking and Compacting: At the second discharge station, the pressing and transfer structure transfers a predetermined number of abdominal pads to the stacking mechanism; in the stacking mechanism, multiple abdominal pads are stacked on top of each other and compacted.

[0012] S7 Binding: The discharge structure transfers the abdominal pads in the stacking mechanism to the binding structure. During the transfer, the discharge structure clamps the upper and lower sides of the abdominal pads. At the binding structure, the abdominal pads are bound.

[0013] S8 discharge: The discharge structure sends the bundled abdominal pads out of the binding structure and outputs them.

[0017] Specifically, in this embodiment of the invention, for the longitudinal folding assembly at the longitudinal folding station: there are two longitudinal folding plates, namely a large longitudinal folding plate and a small longitudinal folding plate. The large longitudinal folding plate, the small longitudinal folding plate, and the transverse folding assembly are arranged sequentially from the inside out and are adjacent to each other. Both the large longitudinal folding plate and the small longitudinal folding plate are arranged along the front-back direction, and their outer ends are rotatably mounted on the loading groove via a front-back longitudinal pivot. The small longitudinal folding plate is floating. In step S4, when folding using the two longitudinal folding plates, the... The large longitudinal folding plate is folded at 1 / 2 of the length of the abdominal pad, and the small longitudinal folding plate is folded at 3 / 4 of the length of the abdominal pad. The large longitudinal folding plate is used to fold the abdominal pad once, and the small longitudinal folding plate is used to fold the abdominal pad a second time. When only one longitudinal folding plate is used for folding, the large longitudinal folding plate does not move, and the small longitudinal folding plate is folded at 1 / 2 of the length of the abdominal pad. The small longitudinal folding plate is used to fold the abdominal pad once. When the longitudinal folding assembly is not used, neither of the two longitudinal folding plates works.

[0018] In step S3, when the folding transfer structure feeds the material, it first transfers the abdominal pad to the rear and upper part of the placement area of ​​the second feeding station; the blowing device operates, and the folding transfer structure moves forward to bring the abdominal pad directly above the placement area. The folding transfer structure then descends to place the abdominal pad in the placement area, and returns to its original position after placement. When the abdominal pad is placed in the placement area, its front end is located in front of the transverse folding assembly. When folding with two longitudinal folding plates, the rear end of the abdominal pad is located in front of the large longitudinal folding plate. When folding with only one longitudinal folding plate, the rear end of the abdominal pad is located in front of the small longitudinal folding plate. When folding with a Z-shaped folding mechanism, the rear end of the abdominal pad is located in front of the large longitudinal folding plate, and the Z-shaped folding mechanism clamps the abdominal pad at the small longitudinal folding plate.

[0019] Specifically, in this embodiment of the invention, for the transverse folding assembly at the longitudinal folding station: two transverse folding plates are located on the front and rear sides of the placement plate, respectively, and are rotatably mounted on the loading slot via a left-right transverse pivot; at the transverse folding station, the transverse folding pressure plate is located directly above the placement plate; at the second feeding station, the right end of the right transverse folding plate extends to the right relative to the loading slot and its right part is curved upward from left to right, and the front right side of the loading slot has a notch for the transverse folding plate to pass through; in step S5, one transverse folding plate away from the X-ray tracking line moves first, and the other transverse folding plate moves later with a flip angle of less than 180°; the folding positions of the two transverse folding plates are located at 1 / 3 and 2 / 3 of the width of the abdominal pad after longitudinal folding, respectively.

The two second grippers are arranged back-to-back and can move up and down. The second grippers are arranged in the left-right direction and can move left and right, clamping the upper and lower sides of the folded abdominal pad. Notches for the second grippers are provided at the middle of the outer end of the placement plate and the middle of the outer end of the loading groove. One second gripper feeds material at the second discharge station, and the other second gripper discharges material at the stacking groove. In the steps... In S6, during feeding, one second gripper first descends to face the placement plate, then moves towards the second discharge station to the placement plate, clamps the upper and lower sides of the folded abdominal pad, moves upward first, and then moves away from the second discharge station; during discharge, another second gripper moves towards the stacking groove to the top of the stacking groove, first descends to the adjacent top of the abdominal pad stack, releases the folded abdominal pad, moves away from the stacking groove first to leave the stacking groove, and then moves upward; the 180° rotary table rotates 180° to switch between feeding and discharging.

[0022] Specifically, the discharge structure in this embodiment of the invention includes a two-dimensional moving mechanism capable of forward and backward and vertical movement, a push plate mechanism on the rear side of its slide, and two clamping plates. The two clamping plates are arranged side by side, one fixed and one movable. The fixed clamping plate is located directly in front of the suspended assembly and can be inserted into the suspended assembly backward. The movable clamping plate is located directly above the fixed clamping plate, can move up and down, and can clamp the upper side of the abdominal pad. The push plate mechanism is located between the two clamping plates, adjacent to and above the fixed clamping plate, arranged in the left-right direction, and can move forward and backward. The clamping plates are arranged in the forward and backward direction and include two clamping arms arranged side by side. The rear side of the stacking groove has two rear notches arranged side by side, and the two rear notches allow the two clamping arms to pass through respectively. The upper side of the component has two clearance grooves arranged side by side, and the clearance grooves are arranged in the front-to-back direction; when the fixed clamping plate is inserted into the overlapping groove, the two clamping arms are respectively located in the two rear notches, and their rear parts are respectively located in the two clearance grooves; in step S6, after the folded abdominal pads in the overlapping groove reach a predetermined number, the overlapping pressure plate moves downward to press the abdominal pad stack; in step S7, after the pressing is completed, both clamping plates are inserted into the overlapping groove, and the movable clamping plate moves downward to clamp the upper side of the abdominal pad stack; the two-dimensional moving mechanism first moves upward, then moves backward, and finally moves downward to bring the abdominal pad stack to the binding structure; in step S8, after the binding is completed, the push plate mechanism moves backward to push the abdominal pad stack away from the two clamping plates and push it out of the binding structure.

[0026] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1 See Figure 1-8 Example 1 provides an automated production system for a medical abdominal pad. The system includes a feeding device 1, an air blowing device (not shown), a folding device 2, and a stacking and binding device 3. For ease of description, the feeding device 1 is defined as being located in front of the folding device 2, but this is not intended to limit the scope of this patent.

[0028] The feeding device 1 includes a three-station turntable 11, an ironing structure 12, and three loading plates 13. A first feeding station 4, an ironing station 5, and a first discharging station 6 are sequentially arranged along the rotation direction of the three-station turntable 11. The first discharging station 6 is located at the rear of the three-station turntable 11. The three loading plates 13 are indexed on the three-station turntable 11 and are respectively located at the first feeding station 4, ironing station 5, and first discharging station 6. Specifically, the included angle between two adjacent loading plates 13 is 120°, and the rotation angle of the three-station turntable 11 is 120°. The loading plates 13 are equipped with fixing components for stretching and fixing the abdominal pads; the fixing components include multiple positioning pins and / or positioning clamps, and they must fix at least four corners of the abdominal pads. The first feeding station 4 is equipped with an operator to manually lay the abdominal pads flat on the loading plate 13. The ironing structure 12 is located next to the ironing station 5, directly above the corresponding loading plate 13, and is used to iron the abdominal pad flat (specifically through hot pressing ironing).

[0029] The folding device 2 includes a four-station turntable 21, a longitudinal folding and flattening structure 22, a folding transfer structure 23, a pressing transfer structure 24, a transverse folding pressure plate, and four bidirectional folding structures 25. Along the rotation direction of the four-station turntable 21, there are sequentially arranged a second feeding station 7 (for feeding), a longitudinal folding station 8 (for longitudinal folding and flattening), a transverse folding station 9 (for transverse folding and flattening), and a second discharging station 10 (for discharging). The four bidirectional folding structures 25 are indexed on the four-station turntable 21 and are respectively located at the second feeding station 7, the longitudinal folding station 8, the transverse folding station 9, and the second discharging station 10. Specifically, the included angle between two adjacent bidirectional folding structures 25 is 90°, and the rotation angle of the four-station turntable 21 is 90°. The second feeding station 7 is located at the front of the four-station turntable 21 and is located behind (specifically, directly behind) the first discharging station 6.

[0030] The longitudinal folding and flattening structure 22 is located next to the longitudinal folding station 9. It can move left and right. It includes a Z-shaped folding mechanism and a longitudinal folding pressure plate arranged side by side. It is used to perform Z-shaped folding and flattening.

[0031] The bidirectional folding structure 25 includes a loading slot 51 and a longitudinal folding assembly 52 (for longitudinal folding) and a transverse folding assembly 53 (for transverse folding) arranged sequentially from the inside to the outside. The longitudinal folding assembly 52 may or may not be active, and the Z-shaped folding mechanism may or may not be active. Either the longitudinal folding assembly 52 or the Z-shaped folding mechanism can be active, meaning that the longitudinal folding of this patent can adopt two folding methods: bi-folding and Z-shaped folding. Both the Z-shaped folding mechanism and the longitudinal folding pressure plate can move up and down (controlled independently). The Z-shaped folding mechanism is used to fold the abdominal pad in a Z-shape. The longitudinal folding assembly 52 includes one or more (usually two) longitudinal folding plates 41 that can be flipped toward the transverse folding assembly 53 (flipping angle approximately 180°), which are used to fold the abdominal pad in the longitudinal direction once or multiple times. The abdominal pad after Z-shaped folding or bi-folding is located on the transverse folding assembly 53, and the longitudinal folding pressure plate is used to press the longitudinally folded abdominal pad tightly. The transverse folding pressure plate is located next to the transverse folding station 9, directly above the placement plate 42 of the transverse folding station 9. It can move up and down and is a rectangular plate that mates with the folded abdominal pad and is arranged in the left and right direction. It is used to move downward to press the folded abdominal pad. For the bidirectional folding structure 25 at the longitudinal folding station 8: the longitudinal folding plate 41 is rotatably mounted on the loading groove 51 via a longitudinal pivot (driven by a corresponding structure) in the front and rear directions. The transverse folding assembly 53 includes a central placement plate 42 (fixed on the loading slot 51) and two transverse folding plates 43 on its front and rear sides. Both transverse folding plates 43 can be folded toward the placement plate 42 (the flip angle is about 180°). They are rotatably mounted on the loading slot 51 via left and right transverse pivots (driven by corresponding structures). Their sequential actions fold the longitudinally folded abdominal pad into three transverse folds. Specifically, the transverse folding plate 43 away from the X-ray tracking line moves first, and the other transverse folding plate 43 moves later to ensure that the X-ray tracking line is located on the upper side of the folded abdominal pad.

[0032] The folding transfer structure 23 is located between the first discharge station 6 and the second feed station 7, and is used to transfer the ironed abdominal pad from the first discharge station 6 to the second feed station 7.

[0033] The air blowing device is located on the left or right side of the front of the second feeding station 7, next to the X-ray tracking line. It is used to blow the X-ray tracking line into the underside of the abdominal pad before the abdominal pad is transferred to the corresponding bidirectional folding structure 25 by the folding transfer structure 23. Specifically, the air blowing device includes multiple (specifically three) bamboo-joint air blowing tubes, which allow the X-ray tracking line to fold along the diagonal of the abdominal pad and in its vicinity on the underside of the abdominal pad.

[0034] The overlapping and binding device 3 includes an overlapping mechanism 31, a discharge structure 32, and a binding structure 33. The overlapping and binding device 3 and the longitudinal folding and flattening structure 22 are located on the left and right sides of the four-station turntable 21, respectively. The overlapping mechanism 31 is located next to the second discharge station 10. The pressing and transferring structure 24 is located between the overlapping mechanism 31 and the second discharge station 10 and is used to transfer the folded abdominal pad from the second discharge station 10 to the overlapping mechanism 31.

[0035] Specifically, the loading plate 13 is a rectangular plate that matches the size of the abdominal pad, and it is arranged radially along the three-station turntable 11. Specifically, the loading plate 13 of the first discharge station 6 is arranged in the front-to-back direction; the loading plates 13 of the first feeding station 4 and the ironing station 5 are both arranged at an angle. The loading trough 51 is a rectangular trough (larger than the abdominal pad) that can accommodate the abdominal pad, and it is arranged radially along the four-station turntable 21. Specifically, the loading trough 51 on the second feeding station 7 and the transverse folding station 9 is arranged in the front-to-back direction, and the loading trough 51 on the longitudinal folding station 8 and the second discharge station 10 is arranged in the left-to-right direction.

[0036] Example 2 See Figure 1-8 Example 2 provides an automated production system for medical abdominal pads, whose structure is basically the same as that of Example 1, except that: in this example, the first feeding station 4 is located on the front left side of the three-station turntable 11, the ironing station 5 is located on the front right side of the three-station turntable 11, and the ironing structure 12 is located on the right side of the three-station turntable 11. The X-ray tracking line of the abdominal pad on the first discharging station 6 is located on the front right side of the abdominal pad; the air blowing device is located on the front right side of the second feeding station 7 and folds the X-ray tracking line to the left on the lower side of the abdominal pad. The longitudinal folding station 8, the transverse folding station 9, and the second discharging station 10 are located on the right, rear, and left sides of the four-station turntable 21, respectively, and the longitudinal folding and flattening structure 22 is located on the right side of the four-station turntable 21, while the stacking mechanism 31 is located on the left side of the four-station turntable 21. With the first discharge station 6 as the reference, the three-station turntable 11 rotates to the left; with the second feed station 7 as the reference, the four-station turntable 21 rotates to the right. The rotation speeds of the three-station turntable 11 and the four-station turntable 21 are coordinated.

[0037] The fixing component includes five positioning pins, four of which are located at the four corners of the abdominal pad, and the remaining pin is located at the center of the back of the abdominal pad. Of course, the fixing component can also adopt other methods, such as four positioning clips and two sets of positioning pins (including multiple positioning pins arranged side by side in front and behind, which can move synchronously in the left and right and upward to achieve automatic stretching).

[0038] The ironing structure 12 is located directly above the abdominal pad at the ironing station 5. It can move up and down (specifically driven by a corresponding cylinder), and its positioning is designed to avoid the positioning pin. When the ironing structure 12 is in the low position, it presses against the upper side of the abdominal pad.

[0039] The folding transfer structure 23 can move forward and backward and vertically, and it is equipped with four first grippers (specifically pneumatic grippers, driven synchronously). The four first grippers (arranged in a rectangular shape) can clamp the four corners of the abdominal pad respectively, and they are all vertically positioned.

[0040] The pressing and transfer structure 24 includes a 180° rotary table and two second grippers (specifically pneumatic grippers) on its left and right sides. The two second grippers are arranged back-to-back and can move up and down (individually controlled). The second grippers are arranged in the left and right direction and can move in the left and right directions, clamping the upper and lower sides of the folded abdominal pad. Notches for the second grippers to work are provided at the middle of the outer end of the storage plate 42 and the middle of the outer end of the loading groove 51 (arranged radially along the four-station rotary table 21). One second gripper feeds material at the second discharge station 10 (moving downwards, then left and right (away from the stacking mechanism 31), and then upwards), while the other second gripper discharges material at the stacking mechanism 31 (moving downwards, then left and right (away from the stacking mechanism 31), and then upwards) to increase speed. After one feeding and discharging cycle, both second grippers move upwards to the highest position, and the 180° rotary table rotates 180°. Of course, the pressing and transfer structure 24 can also adopt other structures, such as the single-gripper structure shown in the figure.

[0041] At the longitudinal folding station 8, two rotating motors 45 are arranged side-by-side on the outer side (specifically the right side) of the loading trough 51. Two transverse folding plates 43 are rotatably mounted on the loading trough 51 at their ends (front or rear) near the placement plate 42 via transverse shafts. The two rotating motors 44 are respectively connected to the outer ends (specifically the right ends) of the two transverse shafts. At the longitudinal folding station 8, the rotating motors 44 and the corresponding transverse folding plates 43 are adjustable on the loading trough 51, allowing the two transverse folding plates 43 to be adjusted to move away from or closer to each other. At the transverse folding station 9, when using the transverse folding assembly 53 for transverse folding, the folding positions of the two transverse folding plates 43 (specifically at the transverse shafts) are located at 1 / 3 and 2 / 3 of the width of the longitudinally folded abdominal pad, respectively. At the second discharge station 10, a second gripper is located between the two rotating motors 44. At the longitudinal folding station 8: the transverse folding plate 43 and the shelf 42 are located on the same horizontal plane, the left and right sides of the transverse folding plate 43 and the shelf 42 are flush, and the front and back width of the transverse folding plate 43 is larger than the front and back width of the shelf 42.

[0042] The longitudinal folding and flattening structure 22 includes a lateral moving mechanism, a Z-shaped folding mechanism, and a longitudinal folding pressure plate. The lateral moving mechanism is arranged in the left-right direction and can move in the left-right direction. The Z-shaped folding mechanism is located inside the slide of the lateral moving mechanism (on the side closer to the four-station turntable 21, specifically the left side) and can move up and down. The longitudinal folding pressure plate is located outside the slide of the lateral moving mechanism (specifically the right side) and can move up and down. It is a rectangular plate that cooperates with the longitudinally folded abdominal pad and is arranged in the front-back direction. At the longitudinal folding station 8, the Z-shaped folding mechanism includes two third grippers (specifically pneumatic grippers, synchronously driven) arranged side by side. The two third grippers are located at the front and rear of the abdominal pad, respectively. The third grippers are vertically arranged and their two gripping arms are arranged side by side. During Z-folding, the third grippers are located at 1 / 3 of the length of the abdominal pad. After clamping the abdominal pad, they move upward first and then outward. When the Z-shaped folding mechanism moves outward to the outer end of the abdominal pad (specifically the right end), the third grippers release. After longitudinal folding, the longitudinal folding pressure plate moves inward (specifically to the left) to directly above the transverse folding assembly 53, and then moves downward to achieve pressing. After pressing is completed, the transverse moving mechanism moves outward (specifically to the right).

[0043] The stacking mechanism 31 is positioned directly opposite the second discharge station 10 and includes a stacking groove 61, a lifting base plate 62, a suspension assembly, and a stacking pressure plate. The stacking groove 61 is a rectangular groove (arranged along the front-to-back direction) that mates with the folded abdominal pads. It has a side notch (specifically a vertically oriented strip notch with an open top) on its right side for inserting the second gripper. The lifting base plate 62 is located in the lower part of the stacking groove 61 and can move up and down in a step-by-step manner to maintain a constant top height of the abdominal pad stack. The suspension assembly is located above the lifting base plate 62 and supports the abdominal pad stack, allowing the insertion of a fixing clamp. The stacking pressure plate is located directly above the stacking groove 61 and can move up and down (specifically driven by a cylinder). It mates with the stacking groove 61 and can move downwards into the stacking groove 61, pressing against the upper side of the abdominal pad stack. Specifically, it is a horizontally oriented rectangular plate. The discharge structure 32 can move forward and backward and vertically. It can transfer the stacked abdominal pads from the stacking groove 61 to the binding structure 33 and push the bound abdominal pads backward. When the abdominal pads in the stacking groove 61 reach a predetermined number, the stacking pressure plate moves downward and presses against the upper side of the abdominal pads to perform compression.

[0044] Specifically, the discharge structure 32 includes a two-dimensional moving mechanism 63 capable of forward and backward and vertical movement, a pusher mechanism 65 on the rear side of its slide, and two clamping plates 64. The two clamping plates 64 are arranged side by side, one fixed and one movable. The fixed clamping plate is located directly in front of the suspended assembly and can be inserted into the suspended assembly. The movable clamping plate is located directly above the fixed clamping plate and can move up and down (specifically driven by a corresponding cylinder), clamping the upper side of the abdominal pad. The pusher mechanism 65 is located between the two clamping plates 64, adjacent to and above the fixed clamping plate, arranged in the left-right direction, and can move forward and backward (specifically driven by a corresponding cylinder). The clamping plates 64 are arranged in the forward and backward direction and include two clamping arms arranged side by side (arranged in the forward and backward direction with a gap between them). The rear side of the stacking groove 61 has two rear notches arranged side by side (specifically, vertically arranged strip notches with open tops), and the two rear notches allow the two clamping arms to pass through respectively. For the movable clamping plate: a protrusion (specifically a rectangular plate with rounded corners on the left) is provided on the left clamping arm. The protrusion is coplanar with the clamping arm, located on the left side of the clamping arm, at the location of the binding strap during binding, and its left end is located adjacent to the right side of the left end of the abdominal pad, which is used to ensure the binding effect. Two clearance grooves are provided side by side on the upper side of the suspended component, which are arranged in the front-back direction and are specifically rectangular grooves. When the fixed clamping plate is inserted into the overlapping groove 61, the two clamping arms are respectively located in the two rear notches, and their rear parts are respectively located in the two clearance grooves. After pressing, both clamping plates 64 are inserted into the overlapping groove 61, and the movable clamping plate moves downward to clamp the upper side of the abdominal pad. The two-dimensional moving mechanism 63 first moves upward, then backward, and finally downward to bring the abdominal pad to the binding structure 33. After binding, the push plate mechanism 65 moves backward to push the abdominal pad away from the two clamping plates 64 and push it out of the binding structure 33.

[0045] Among them, the storage plate 42, the horizontal folding plate 43 and the vertical folding plate 41 are all rectangular plates. The horizontal folding plate 43 (the hollow holes on it are specifically round holes) and the vertical folding plate 41 (the hollow holes on it are specifically strip holes) are both provided with multiple hollow holes. The horizontal folding plate 43 is located near the outer end of the storage groove 51.

[0046] Example 3 See Figure 1-8Example 3 provides an automated production system for a medical abdominal pad, the structure of which is basically the same as that of Example 3, except that: in this example, there are two longitudinal folding plates 41, namely a large longitudinal folding plate and a small longitudinal folding plate. The large longitudinal folding plate, the small longitudinal folding plate, and the transverse folding assembly 53 are arranged sequentially from the inside to the outside and are adjacent to each other. The large longitudinal folding plate, the small longitudinal folding plate, the transverse folding plate 43, and the placement plate 42 are located on the same horizontal plane, and the width of the large longitudinal folding plate is greater than the width of the small longitudinal folding plate. Specifically, the length of the large longitudinal folding plate (radial along the four-station turntable 21) is approximately twice the length of the small longitudinal folding plate, and the lengths of the small longitudinal folding plate and the transverse folding plate 43 are approximately the same.

[0047] For the bidirectional folding structure 25 at longitudinal folding station 8: both the large and small longitudinal folding plates are arranged in the front-to-back direction, and their outer ends (specifically the right ends) are rotatably mounted on the loading groove 51 via a longitudinal pivot. When using two longitudinal folding plates 41 for folding, the folding position of the large longitudinal folding plate (specifically at the longitudinal pivot) is 1 / 2 of the length of the abdominal pad (counting from the inside to the outside), and the folding position of the small longitudinal folding plate is 3 / 4 of the length of the abdominal pad (counting from the inside to the outside). The large longitudinal folding plate is used to fold the abdominal pad once, and the small longitudinal folding plate is used to fold the abdominal pad a second time. When using only one longitudinal folding plate 41 for folding, the large longitudinal folding plate does not move, and the folding position of the small longitudinal folding plate is 1 / 2 of the length of the abdominal pad. The small longitudinal folding plate is used to fold the abdominal pad once. When the longitudinal folding assembly 52 is not used, neither of the two longitudinal folding plates 41 works.

[0048] Preferably, the small longitudinal folding plate is floating (it can swing up and down slightly) to facilitate the third gripper to grasp the abdominal pad.

[0049] When the folding transfer structure 23 is fed, it first transfers the abdominal pad to the upper rear of the placement area of ​​the second feeding station 7. The air blowing device operates, and the folding transfer structure 23 moves forward to bring the abdominal pad directly above the placement area. The folding transfer structure 23 then descends to place the abdominal pad in the placement area (used for placing and folding the abdominal pad, located near the outer end (specifically the front end) of the bidirectional folding structure 25), and returns to its original position after placement. When the abdominal pad is placed in the placement area, its front end is located in front of the transverse folding assembly 53. When folding using two longitudinal folding plates 41, the rear end of the abdominal pad is located behind the large longitudinal folding plate. When folding using only one longitudinal folding plate 41, the rear end of the abdominal pad is located behind the small longitudinal folding plate. When folding using a Z-shaped folding mechanism, the rear end of the abdominal pad is located in front of the large longitudinal folding plate, and the Z-shaped folding mechanism clamps the abdominal pad at the small longitudinal folding plate (floating setting).

[0050] Example 4 Example 4 provides an automated production system for medical abdominal pads, whose structure is basically the same as that of Example 2, except that: in this example, at the second feeding station 7, the right end of the right-side transverse folding plate 43 extends to the right relative to the loading trough 51 to catch the X-ray tracking line hanging down during the transfer process, and its right part is curved upward from left to right (slightly bent) to ensure the success rate of X-ray tracking line folding. The front right side of the loading trough 51 has a notch for the transverse folding plate 43 to pass through. The setting of the right-side transverse folding plate 43 should ensure that it can be set laterally, and the flipping angle is slightly less than 180°.

[0051] Example 5 See Figure 1-13 Example 5 provides an automated production method for a medical abdominal pad, employing the aforementioned automated production system for medical abdominal pads. The method includes: S1 Manual feeding and stretching: At the first feeding station 4, the abdominal pad is manually fixed on the loading plate 13 and stretched manually or automatically; after the fixing is completed, the three-station turntable 11 rotates.

[0052] Specifically, the abdominal pad is manually stretched while being secured to the five positioning pins.

[0053] S2 Ironing: At ironing station 5, ironing structure 12 moves downward to iron the abdominal pad; after ironing is completed, ironing structure 12 returns to its original position, and the three-station turntable 11 rotates.

[0054] S3 workbench transfer and X-ray tracking line folding: At the first discharge station 6, the folding transfer structure 23 transfers the ironed abdominal pad from the first discharge station 6 to the second feed station 7; during the transfer process, the air blowing device blows the X-ray tracking line into the underside of the abdominal pad.

[0055] Specifically, when the folding transfer structure 23 is feeding, it first transfers the abdominal pad to the rear upper part of the placement area of ​​the second feeding station 7. The air blowing device operates, and the folding transfer structure 23 moves forward to bring the abdominal pad directly above the placement area. The folding transfer structure 23 then descends to place the abdominal pad in the placement area, and returns to its original position after placement. When the abdominal pad is placed in the placement area, its front end is located in front of the transverse folding assembly 53. When folding using two longitudinal folding plates 41, the rear end of the abdominal pad is located behind the large longitudinal folding plate. When folding using only one longitudinal folding plate 41, the rear end of the abdominal pad is located behind the small longitudinal folding plate. When folding using a Z-shaped folding mechanism, the rear end of the abdominal pad is located in front of the large longitudinal folding plate, and the Z-shaped folding mechanism clamps the abdominal pad at the small longitudinal folding plate (floating setting).

[0056] S4 Longitudinal Folding and Flattening: At longitudinal folding station 8, either the longitudinal folding component 52 of the bidirectional folding structure 25 or the Z-shaped folding mechanism of the longitudinal folding and flattening structure 22 works. The longitudinal folding component 52 is used to fold the abdominal pad once or multiple times, and the Z-shaped folding mechanism is used to fold the abdominal pad in a Z-shape. When the longitudinal folding component 52 folds, the longitudinal folding plate 41 flips. After longitudinal folding (including bi-folding or Z-shaped folding), the longitudinal folding pressure plate of the longitudinal folding and flattening structure 22 presses the longitudinally folded abdominal pad tightly. After pressing is completed, the four-station turntable 21 rotates.

[0057] Specifically, when using two longitudinal folding plates 41 for folding, the larger longitudinal folding plate is folded at half the length of the abdominal pad, and the smaller longitudinal folding plate is folded at three-quarters the length of the abdominal pad. The larger longitudinal folding plate is used to fold the abdominal pad once, and the smaller longitudinal folding plate is used to fold the abdominal pad a second time. When using only one longitudinal folding plate 41 for folding, the larger longitudinal folding plate does not move, and the smaller longitudinal folding plate is folded at half the length of the abdominal pad, used to fold the abdominal pad once. When the longitudinal folding assembly 52 is not used, neither of the two longitudinal folding plates 41 is active.

[0058] S5 Lateral Folding and Flattening: At the lateral folding station 9, the lateral folding assembly 53 of the bidirectional folding structure 25 laterally folds the longitudinally folded abdominal pad. During lateral folding, the two lateral folding plates 43 of the lateral folding assembly 53 flip sequentially. After lateral folding, the lateral folding pressure plate moves downward to press the laterally folded abdominal pad firmly. After pressing is completed, the four-station turntable 21 rotates.

[0059] Specifically, at the lateral folding station 9, one lateral folding plate 43 (specifically the right-side lateral folding plate 43), which is away from the X-ray tracking line, moves first, followed by another lateral folding plate 43 (specifically the left-side lateral folding plate 43, which is designed to be bent), with its flip angle being less than 180°. The folding positions of the two lateral folding plates 43 are located at 1 / 3 and 2 / 3 of the width of the abdominal pad after longitudinal folding, respectively.

[0060] S6 Stacking and Compacting: At the second discharge station 10, the pressing and transfer structure 24 transfers a predetermined number (specifically 5 pieces) of abdominal pads to the stacking mechanism 31. In the stacking mechanism 31, multiple abdominal pads are stacked on top of each other and compacted.

[0061] Specifically, during feeding, one of the second grippers (specifically the second gripper on the right) first descends to face the placement plate 42, then moves towards (specifically to the right) the second discharge station 10 to the placement plate 42, clamping the upper and lower sides of the folded abdominal pads. It then moves upwards and then away from (specifically to the left) the second discharge station 10. During discharge, another second gripper (specifically the second gripper on the left) moves towards (specifically to the left) the stacking groove 61 to directly above it. It first descends to the adjacent upper part of the abdominal pad stack, releasing the folded abdominal pads. It then moves away from (specifically to the right) the stacking groove 61 to leave it, and then moves upwards. The 180° rotary table rotates 180° to switch between feeding and discharging. After the predetermined number of folded abdominal pads in the stacking groove 61 is reached, the stacking pressure plate moves downwards to press the abdominal pad stack together.

[0062] S7 Binding: The discharge structure 32 transfers the abdominal pad in the stacking mechanism 31 to the binding structure 33. During the transfer, the discharge structure 32 clamps the upper and lower sides of the abdominal pad; at the binding structure 33, the abdominal pad is bound.

[0063] Specifically, after pressing, both clamping plates 64 are inserted into the overlapping groove 61, and the movable clamping plate moves downward to clamp the upper side of the abdominal pad. At this time, the push plate mechanism 65 is located in front of the abdominal pad. The two-dimensional moving mechanism 63 first moves upward, then backward, and finally downward to bring the abdominal pad to the binding structure 33. Of course, other methods can also be used.

[0064] S8 Discharge: Discharge structure 32 sends the bundled abdominal pad out of the binding structure 33 and outputs it.

[0065] Specifically, after the binding is completed, the push plate mechanism 65 moves backward to push the abdominal pads away from the two clamping plates 64 and push the binding structure 33 out backward.

[0066] S9 Packaging and Disinfection: Packaging and disinfection are carried out using conventional methods (either using separate equipment or by setting it behind the binding structure 33 to achieve automatic packaging after discharge).

[0067] like Figure 9-12 The product obtained by the method of this patent has a much better appearance than the product obtained by hand.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
