Then, a bag-loading mechanism clamps the bags held by the bag-picking mechanism. The bag-loading mechanism reciprocates between the bag-picking mechanism and the main disc mechanism, conveying the bags one by one to the bag-loading station of the main disc mechanism for initial suction and fixation, thus opening the bag opening. During the intermittent movement of the main disc mechanism, the main disc mechanism rotates the paper bag to the bag-opening mechanism, which hooks the bottom of the bag to fully open it. The fully opened bag is then rotated by the main disc mechanism to the feeding mechanism, where it quantitatively injects stored powder raw materials into the fully opened bag. The bag with injected raw materials is compacted by a vibration mechanism, and then the compacted bag is removed from the main disc mechanism by a bag-transfer mechanism. The paper bag is removed from the machine and conveyed to the M-edge folding mechanism to fold the bag opening into an M-shape. Simultaneously, under the bag-moving action of the moving mechanism, the paper bag with the M-shaped opening folded at the M-edge folding mechanism is conveyed to the M-edge pressing mechanism to press the bag opening back to its original M-shape. Under the pressing of the M-edge pressing mechanism, the paper bag is moved to the shaping and gluing mechanism. The shaping and gluing mechanism sequentially cuts off the excess bag body at the opening of the paper bag containing powder raw materials, folds the cut-off bag opening at 90° and 180° in sequence and squeezes it, and sprays glue into the opening of the bag body while tilting the bag body. The bag body is then conveyed out and squeezed and shaped by the pressing mechanism to make it stronger and more square and beautiful in appearance. It can meet the needs of accurately packaging raw materials of different weights in paper bags of different lengths, widths and models. It has a fast packaging speed, high qualification rate, and the material in the packaged paper bag is fully compacted. The finished product is strong and well-shaped, and the packaging appearance is good, which greatly improves the production efficiency of paper bag packaging products. Attached Figure Description

[0041] The bag storage mechanism 2 is located on one side of the frame mechanism 1. It stores paper bags of different sizes and conveys them towards the bag-picking mechanism 3. The bag-picking mechanism 3 is located on one side of the bag storage mechanism 2 and is used to pick up and remove the paper bags one by one from the bag storage mechanism 2. The bag-feeding mechanism 4 is located between the bag-picking mechanism 3 and the main platen mechanism 5. It reciprocates between the bag-picking mechanism 3 and the main platen mechanism 5, conveying the paper bags picked up by the bag-picking mechanism 3 to the main platen mechanism 5, where they are adhered and fixed by suction cups, and the bag opening is initially opened. The bag-opening mechanism 6 and the feeding mechanism 7 are distributed sequentially along the outer periphery of the main platen mechanism 5. The bag-opening mechanism 6 fully opens the paper bags that have rotated to the bag-opening mechanism 6. The feeding mechanism 7 quantitatively injects the powder raw material to be packaged into the fully opened paper bags that have rotated to the bottom of the feeding mechanism 7. The bag transfer mechanism 9, the M-edge folding mechanism 10, the M-edge pressing mechanism 11, the shaping and glue injection mechanism 12, and the pressing mechanism 13 are distributed sequentially along the side away from the main plate mechanism 5;

[0042] The bag transfer mechanism 9 is used to simultaneously transport the paper bags containing powder raw materials from the main tray mechanism 5 to the M-edge folding mechanism 10, transport the M-edge folded paper bags from the M-edge folding mechanism 10 to the M-edge pressing mechanism 11, and transport the M-edge pressed paper bags from the M-edge pressing mechanism 11 to the shaping and gluing mechanism 12 under the pressing action of the M-edge pressing mechanism 11; the M-edge folding mechanism 10 is used to fold the two sides of the bag opening of the paper bag containing powder raw materials into an M-shape; the M-edge pressing mechanism 11 is used to press the M-shaped bag opening of the paper bag containing powder raw materials; the shaping and gluing mechanism 12 is used to sequentially process the paper bags containing powder raw materials. Excess bag body at the opening is cut off, the cut-off opening is folded 90° and 180° sequentially and squeezed, and the bag body at the opening is tilted while the glue is sprayed into the opening of the bag body; the pressing mechanism 13 is used to squeeze the bag body from the top and sides after the glued bag body is transported to the pressing mechanism 13; the drive mechanism a is connected to the main plate mechanism 5, the bag transfer mechanism 9 and the pressing edge mechanism 11; the drive mechanism a drives the main plate mechanism 5 to rotate intermittently and drives the bag transfer mechanism 9 and the pressing edge mechanism 11 to move back and forth through the set cam divider.

[0043] In an optional embodiment, after the paper bag contains the powder raw material, it is vibrated by the vibration mechanism 8 and then removed from the main plate mechanism 5 by the bag transfer mechanism 9.

[0044] Example 2: The present invention proposes an automated paper bag packaging equipment. Compared with Example 1, this example also discloses the specific structure of the frame mechanism 1; the frame mechanism 1 includes a frame body, a glass door, and a maintenance door;

[0045] Multiple pairs of glass doors are installed evenly along the outer periphery of the frame body on its side surface. Multiple inspection doors are located below the pairs of glass doors and are all detachably installed on the side surface of the frame body. A control box integrating the control system, display screen, and button module is mounted on the frame body via a rotating robotic arm. The control system is used for intelligent control of the various electrical mechanisms in the automated paper bag packaging equipment. The feeding mechanism 7 is installed on the upper surface of the frame body, and its discharge pipe extends into the frame body and is located at the feeding station of the main disc mechanism 5.

[0046] Example 3; as Figure 2 As shown, the present invention proposes an automated paper bag packaging device. Compared with Embodiment 1, this embodiment also discloses the specific structure of the bag storage mechanism 2; the bag storage mechanism 2 includes a bag storage assembly 201, a mounting frame a202, a driving device a203, a protective cover 204, and a brush wheel 205;

[0047] A bag storage assembly 201 is installed within the frame mechanism 1 to store paper bags of different sizes. The structure of the bag storage assembly 201 is functionally identical to that of an automatic bag feeding structure based on a fully automatic packaging machine described in authorization announcement number CN113753323B, and is therefore not described in detail here. A mounting frame a202 is connected to the frame mechanism 1 and is located above the bag storage assembly 201. A brush wheel 205 is rotatably connected to the mounting frame a202 via a rotating shaft. The brush wheel 205 is located directly above the bag outlet side of the bag storage assembly 201, and brush bristles are evenly distributed on its outer circumference. A rotating shaft drives a drive device a203. The drive device a203 is connected to the mounting frame a202. A protective cover 204 covers the upper part of the brush wheel 205 and is connected to the mounting frame a202. The drive device a203 drives the brush wheel 205 to rotate, thereby agitating the paper bags placed in the storage bag assembly 201, ensuring that the paper bags in the storage bag assembly 201 can be picked up by the bag picking mechanism 3.

[0048] Example 4; as Figure 3 As shown, the present invention proposes an automated paper bag packaging device. Compared with Embodiment 3, this embodiment also discloses the specific structure of the bag picking mechanism 3. The bag picking mechanism 3 includes a mounting base a301, a cylinder a303, a tube body 304, a tube connector 305, a mounting frame b, a suction column 307, and a suction cup 308.

[0049] Mounting base a301 connects to frame mechanism 1, cylinder a303 connects to mounting base a301, the telescopic end of cylinder a303 faces the bag outlet side of bag storage assembly 201, and is connected to tube body 304 for communication with vacuum device; multiple suction cups 308 are provided and located on the side away from cylinder a303, suction cups 308 and suction columns 307 correspond one to one, suction cups 308 are connected to one end of suction column 307 and are connected; each suction column 307 is perpendicular to tube body 304, some suction columns 307 are directly connected to tube body 304 and communicate with the inside of tube body 304, the remaining suction columns 307 are connected to tube body 304 through mounting bracket b, and communicate with the inside of tube body 304 through pipe joint 305.

[0050] The paper bag inside the storage bag assembly 201 is pushed to the bag outlet side of the storage bag assembly 201 by the moving component set in conjunction with the brush wheel 205. The cylinder a303 pushes the tube 304 toward the storage bag assembly 201. Multiple suction cups 308 adhere to the paper bag inside the storage bag assembly 201. The vacuum device operates so that the multiple suction cups 308 adsorb the paper bag to remove the paper bag from the storage bag assembly 201.

[0051] Example 5; as Figure 4 As shown, the present invention proposes an automated paper bag packaging device. Compared with embodiment four, this embodiment also discloses the specific structure of the bag loading mechanism 4. The bag loading mechanism 4 includes a mounting base b401, a driving device b402, a linear module 403, a proximity switch a404, a mounting base c405, a bag clamping finger cylinder 406, a bag clamping piece 407, and a proximity switch b409.

[0052] Both proximity switches a404 and b409 are mounted on mounting base b401. Mounting base b401 is connected to frame mechanism 1 and is located above bag-picking mechanism 3. Mounting base b401 is located between bag-picking mechanism 3 and main tray mechanism 5 and is distributed along the line connecting bag-picking mechanism 3 and main tray mechanism 5. Mounting base b401 is provided with a drive mechanism b for driving mounting base c405 to reciprocate between proximity switches a404 and b409 along the length of mounting base b401. The drive mechanism b is selected, but is not limited to, a structure in which drive device b402 and linear module 403 cooperate to move. The operation of drive device b402 drives linear module 403 to drive mounting base c405 to reciprocate between proximity switches a404 and b409 to transport the paper bags taken out by bag-picking mechanism 3 from bag storage assembly 201 to the bag loading station on main tray mechanism 5. The fixed end of the bag-clamping finger cylinder 406 is connected to the mounting base c405, and the two sets of drive ends of the bag-clamping finger cylinder 406 are respectively connected to two bag-clamping plates 407; wherein, a silicone layer 408 is provided on the end face of the two bag-clamping plates 407 that are close to each other.

[0053] When the bag-retrieving mechanism 3 removes the paper bag from the storage assembly 201, the drive mechanism b drives the mounting base c405 to move toward the bag-retrieving mechanism 3 until proximity switch a404 or proximity switch b409 detects the mounting base c405. At this time, the drive mechanism b stops running. At this time, the two clamping plates 407 are located on both sides of the paper bag held by the bag-retrieving mechanism 3. The clamping finger cylinder 406 operates to drive the two clamping plates 407 to move closer to each other to clamp the paper bag, and the bag-retrieving mechanism 3 separates from the paper bag. The drive mechanism b then drives the mounting base c405 to move toward the bag-up position of the main plate mechanism 5 until proximity switch b409 or proximity switch a404 detects the mounting base c405. At this time, the clamped paper bag is located between the two suction nozzles at the bag-up position. The suction nozzles at the bag-up position adsorb the clamped paper bag to complete the bag-up operation.

[0054] The main plate mechanism 5 has a main plate body and a suction nozzle adsorption structure arranged in groups on the main plate body along the circumferential direction of the main plate body. The main plate body is an existing structure selected, but not limited to the main plate structure described in the authorization announcement number CN217074982U; the suction nozzle adsorption structure is a suction nozzle structure connected to the vacuum equipment, which will not be described in detail.

[0055] Starting from the point closest to the bag-loading mechanism 4, the main disc body is sequentially defined along its outer periphery as bag-loading station a, bag-opening station b, unloading station c, vibration station d, vibration station e, vibration station f, bag-transfer station g, and reserved station h; there are eight sets of suction nozzle adsorption structures, which are respectively installed at the above eight stations; the bag-loading mechanism 4 moves the clamped paper bag to the suction nozzle adsorption structure at the bag-loading station, and is located between the suction nozzles on both sides. The paper bag is adsorbed by the suction nozzles under negative pressure. After the paper bag is adsorbed at the bag-loading station, it is moved from the bag-loading station to the bag-opening station by the rotation of the main disc body.

Compared with Embodiment 5, this embodiment also discloses the specific structure of the bag opening mechanism 6.

A conveyor belt is fitted around the outside of the placement groove, and the paper bags are placed on the conveyor belt. The conveyor belt moves synchronously with the bag-transferring mechanism 9 as the paper bags are moved.

[0067] The operation of the bag transfer mechanism 9 is as follows: the paper bag after being vibrated at the vibration station is moved to the M-edge folding mechanism 10; the drive device c908 drives the clamping fixing plate 903 to move along the width direction of the pad plate 901 to extend the bag hook 912 into one side of the paper bag, at which time the paper bag is located between the bag hook 912 and the clamping plate a917; the drive device d914 drives the mounting seat h916 and the bag hook fixing seat to move toward the side closer to the paper bag, thereby clamping the paper bag between the bag hook 912 and the clamping plate a917; the drive mechanism a drives the left and right swing transmission shaft 919 to rotate, driving the moving plate 902 to move toward the M-edge folding mechanism 10 in the length direction of the pad plate 901, so as to move the paper bag to the M-edge folding mechanism 10;

[0068] The bag transfer mechanism 9 returns to its original position: the drive device d914 drives the mounting base h916 and the bag hook fixing base to move away from the paper bag, and the drive device c908 drives the clamp fixing plate 903 to move away from the paper bag along the width direction of the pad plate 901; the drive mechanism a drives the left and right swing transmission shaft 919 to rotate in the opposite direction, driving the moving plate 902 to move towards the main plate body along the length direction of the pad plate 901.

[0069] Example 9; as Figure 8 As shown, the automated paper bag packaging equipment proposed in this invention, compared with Embodiment 8, also discloses the specific structure of the folding edge mechanism 10.

The fixed end of the drive device e1002 is connected to the bracket 1001, and the drive end of the drive device e1002 is connected to the mounting base i1003. The drive device e1002 uses, but is not limited to, a cylinder to drive the mounting base i1003 to move toward or away from the placement slot. There are two drive devices f1004, which are arranged side by side and are both connected to the mounting base i1003. The drive directions of the two drive devices f1004 are opposite, and the drive end of each drive device f1004 is connected to the upright plate a1005. The drive device f1004 uses, but is not limited to, a cylinder to drive the two upright plates a1005 to move synchronously. The upright plates b1006 are arranged in pairs, with each pair connected to the mounting base i1003. The two pairs of upright plates b1006 are located between the two upright plates a1005, with a gap between each pair of upright plates b1006 for the insertion of the upright plate a1005. When the compacted paper bag is moved below the M-shaped folding mechanism 10, the drive device e1002 moves the mounting base i1003 toward the paper bag. At this time, the two pairs of upright plates b1006 extend into the inside of the paper bag, while the two upright plates a1005 are located on the outside of the paper bag. The two drive devices f1004 operate synchronously, driving the two upright plates a1005 toward the two pairs of upright plates b1006, causing the upright plates a1005 to pull the paper bag into the gap between the two upright plates b1006, forming an M-shaped fold on both sides of the paper bag opening, restoring the paper bag opening to its original M-shape. After the hem is folded, the two drive devices f1004 reset first, and then the drive device e1002 resets.

[0071] Example 10; as Figure 9 As shown, the automated paper bag packaging equipment proposed in this invention, compared with Embodiment Nine, also discloses the specific structure of the pressing edge mechanism 11. The pressing edge mechanism 11 includes a mounting plate b1101, a rotating shaft 1102, a mounting base j1103, a driving device g1104, a pressing block 1105, a connecting shaft a1106, and a connecting shaft b1107;

[0072] Mounting plate b1101 is slidably connected to frame mechanism 1; wherein, mounting plate b1101 is connected to frame mechanism 1 by means of, but not limited to, a slide rail and a slider; mounting plate b1101 moves along the length direction of the placement groove, that is, along the distribution direction of the folding edge mechanism 10, the pressing edge mechanism 11, and the shaping and gluing mechanism 12. In the initial state, mounting plate b1101 is located on the side closer to folding edge mechanism 10.

[0073] Two mounting bases j1103 are provided, arranged side by side and each connected to the lower end face of the mounting plate b1101.

[0075] After the paper bag is folded by the edge-folding mechanism 10 and conveyed to the edge-pressing mechanism 11 by the bag-transferring mechanism 9, the paper bag is positioned between two pressing blocks 1105. Two driving devices g1104 operate to drive the pressing blocks 1105 to move and press the folded paper bag between the two pressing blocks 1105. The driving mechanism a drives the rotating shaft 1102 to rotate, and through the connecting shafts a1106 and b1107, it drives the mounting plate b1101 to move to the side closer to the shaping and gluing mechanism 12. The paper bag enters the shaping and gluing mechanism 12 for processing. The edge-pressing mechanism 11 resets and moves again to the side closer to the edge-folding mechanism 10 under the drive of the driving mechanism a.

[0076] Example 11; as Figure 10 and Figure 11 As shown, the automated paper bag packaging equipment proposed in this invention, compared with Embodiment 10, also discloses the specific structure of the shaping and gluing mechanism 12. The shaping and gluing mechanism 12 includes a mounting frame c1201, an adjustment mechanism b1202, a drive device h1204, a knife holder 1205, a cutter b1207, a drive device i1208, an edge folding plate a1209, an edge folding plate b1210, a drive device j1211, a dynamic pressure edge plate 1213, a fixed pressure edge plate 1214, a beveled opening plate 1215, a drive device k1216, and a glue spraying pipe 1217;

[0077] Mounting frame c1201 is connected to frame mechanism 1 via adjusting mechanism b1202. Adjusting mechanism b1202 has the same structure as adjusting mechanism a, and its height can be adjusted to meet the needs of cutting paper bags of different heights. Two guide members 1203 are arranged side-by-side at the end of mounting frame c1201 facing the edge pressing mechanism 11; a guide channel for the paper bag to pass through is provided between the two guide members 1203. Mounting frame c1201 has a processing channel for the upper end of the paper bag to pass through; the processing channel is connected to the guide channel, and along the direction away from the guide channel, a bag cutting station, an edge folding station, an edge pressing station, and a beveled glue spraying station are sequentially provided at the processing channel.

[0078] The cutter b1207 is located at the bag cutting station and connected to the inner wall of the processing channel; the cutter holder 1205 is connected to the drive end of the drive device h1204, and the drive device h1204 is connected to the mounting bracket c1201; the end face of the cutter holder 1205 facing the cutter b1207 is provided with a cutter a1206; the cutter a1206 and the cutter b1207 cooperate to cut off the excess bag body at the upper port of the paper bag.

[0079] The drive unit i1208 is located at the folding station and on one side of the processing channel. The drive unit i1208 is connected to the mounting frame c1201. The drive end of the drive unit i1208 is connected to the folding plate a1209, which is used to fold the upper opening of the paper bag at the folding station to 90°. The drive unit k1216 is located at the folding station and above the processing channel. The drive end of the drive unit k1216 faces the folding plate a1209 and is connected to the folding plate b1210, which is used to fold the upper opening of the paper bag from 90° to 180°.

[0080] The fixed pressure plate 1214 is located at the pressing station and is connected to the inner wall of the processing channel; the drive device j1211 is connected to the mounting bracket c1201, and the drive end of the drive device j1211 faces the fixed pressure plate 1214 and is connected to the moving pressure plate 1213.

[0081] The inclined plate 1215 is connected to the mounting bracket c1201 via an inclined plate connecting seat. The inclined plate 1215 and the inclined plate connecting seat are adjustable to adjust the distance between the inclined plate 1215 and the inner wall of the processing channel. The end face of the inclined plate 1215 and the inner wall of the processing channel form a guide channel for the upper end of the paper bag to pass through. When the upper end of the paper bag passes through the guide channel, the upper end of the paper bag tilts out an angled opening under the guidance of the inclined plate 1215. The glue spraying pipe 1217 is connected to the frame mechanism 1. The glue inlet end of the glue spraying pipe 1217 is connected to the glue outlet end of the glue spraying system. The glue outlet end of the glue spraying pipe 1217 faces the opening and is used to spray glue from inside the glue spraying pipe 1217 into the opening formed at the upper end of the paper bag after the paper bag is detected. The paper bag is detected during glue spraying by a bag detection photoelectric sensor.

[0082] The height of the mounting frame c1201 is adjusted by adjusting mechanism b; under the clamping action of the pressing edge mechanism 11 and the conveyor belt, the paper bag enters the processing channel from the guide channel between the two guide members 1203; driven by the transmission mechanism, the paper bag moves sequentially along the bag cutting station, folding station, pressing edge station, and oblique nozzle glue spraying station with each action of the transmission mechanism; after the paper bag enters the bag cutting station, the upper end of the paper bag is located between cutter a1206 and cutter b1207, and the drive device h1204 drives cutter a1206 to move towards cutter b1207, and cutter a1206 and cutter b1207 cooperate to press the paper bag... Excess bag material at the top port is cut off; then the paper bag enters the folding station, where drive device i1208 moves the folding plate a1209, folding the top opening of the paper bag to 90° under the constraint of mounting bracket c1201. Drive device i1208 then resets, and drive device k1216 moves the folding plate b1210 to fold the top opening of the paper bag from 90° to 180°. The paper bag then enters the pressing station, where the folded 180° top end is positioned between the fixed pressing plate 1214 and the moving pressing plate 1213. Drive device j1211 moves the moving pressing plate 1213 toward the fixed pressing plate 1214 to press the top end of the paper bag. The paper bag then enters the guide channel, tilting at an angled opening under the guidance of the inclined opening plate 1215. After the paper bag is detected at the inclined opening glue spraying station, the glue spraying system sprays glue from the glue spraying pipe 1217 into the opening.

[0083] Example 12; as Figure 12 As shown, the automated paper bag packaging equipment proposed in this invention, compared with Embodiment Eleven, also discloses the specific structure of the pressing mechanism 13. The pressing mechanism 13 includes a mounting base k1301, a driving device l1302, a driving device m1304, a pressure plate b1305, and a mounting frame d;

[0084] Mounting base k1301 is located above the conveyor belt and is connected to frame mechanism 1. The fixed end of drive device l1302 is connected to mounting base k1301, and the drive end of drive device l1302 faces the conveyor belt.

There are two drive devices m1304, which are located on both sides of the conveyor belt and are connected to mounting frame d. Pressure plate b1305 corresponds to drive device m1304 one-to-one. Pressure plate b1305 is connected to the drive end of drive device m1304, and the two pressure plates b1305 are located between the two drive devices m1304.

[0085] After the paper bags are coated with glue, they are conveyed to the pressing mechanism 13 by the conveyor belt and positioned between the two pressing plates b1305. The drive device l1302 drives the pressing plate a1303 to press the upper part of the paper bag, making the glued paper bag stick more firmly. The two drive devices m1304 synchronously drive the two pressing plates b1305 to squeeze and shape the two sides of the paper bag, making it stronger and more square and beautiful in appearance. After pressing, the conveyor belt moves the paper bags from the pressing mechanism 13 one by one, and then the robot arm clamps and transfers them out of the equipment.

[0086] Example 13; This invention proposes an automated paper bag packaging device. Compared to Example 12, this example further discloses the specific structure of the drive mechanism a. The drive mechanism a includes an encoder, a main motor, a main transmission reducer, a transmission bearing housing, a cam divider, a divider main shaft gear, a divider output gear, a main shaft gear, a main shaft, cam a, cam b, a bag opening swing arm, a follower bearing, a bag moving swing arm, a bag moving pull rod, a bearing with a vertical seat, a square bearing, and an encoder mounting base, etc. Those skilled in the art can construct the drive mechanism a using the above structure and its supporting structures according to the technical manual and the description of this technical solution. The driving process of the drive mechanism a is as follows:

[0087] Drive mechanism a is mounted on frame mechanism 1. Drive mechanism a provides power to main disc mechanism 5, bag transfer mechanism 9, and pressing edge mechanism 11 through a main motor. The main motor drives the main drive reducer to rotate 360°, which in turn rotates the main shaft gear of the divider 360° and the output gear of the divider rotates 45°. Since the divider has intermittent motion, when the output shaft of the main drive reducer rotates from 0 to 120 degrees, the output gear of the divider rotates from 0 to 45°; when the output shaft of the main drive reducer rotates from 120 to 360°, the output gear of the divider does not rotate. Thus, the main disc mechanism rotates intermittently under the drive of drive mechanism a. That is, drive mechanism a is driven by a main motor and outputs power through the cam divider. The main shaft gear of the divider drives the main shaft gear to rotate, which in turn drives the main shaft to rotate. The main shaft then drives cams a and b to rotate. Cam a drives the bag-opening swing arm via a follower bearing. The bag-opening swing arm transmits the motion to the main disc mechanism via a connecting rod, causing the main disc mechanism to rotate intermittently. Cam b drives the bag-transfer swing arm via a follower bearing. The bag-transfer swing arm transmits the motion to the left-right swing transmission shaft 919 of the bag-transfer mechanism 9 and the rotating shaft 1102 of the pressing edge mechanism 11 via a bag-transfer pull rod. The drive mechanism a obtains the real-time motion angle of the main shaft through an encoder. The timing of the actions of other components of the machine is controlled by setting the angle information obtained from the encoder.

[0088] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
