DETAILED DESCRIPTION

[0043] The following will be described in detail below with reference to the accompanying Figure 1 - the accompanying Figure 12 The present application will be described in further detail.

[0044] Embodiment 1:

[0045] As Figure 1As shown, in the embodiment, the conveying belt 3 is used to convey the book block 4 discharged from the delivery; the collating mechanism 1 comprises a placing table 12, a paper delivery assembly 13 and a lifting assembly 15, the placing table 12 is used to place the stacked book block 4, the paper delivery assembly 13 is located below the placing table 12 and between the placing table 12 and the rack 11, and is used to discharge the book block 4 on the placing table 12, and the lifting assembly 15 is used to lift the stacked book block 4.

[0046] The book block 4 with different contents is placed on the plurality of collating mechanisms 1, the paper delivery assembly 13 extracts the bottom of the stacked book block 4 on the placing table 12, and the lifting assembly 15 lifts the book block 4 stacked above the bottom book block 4 at the moment when the paper delivery assembly 13 extracts, and the cooperation of the paper delivery assembly 13 and the lifting assembly 15 achieves that the stacked book block 4 in each collating mechanism 1 is extracted from the bottom and falls on the conveying belt 3, and the falling time of the book block 4 in each collating mechanism 1 is close, and each type of book block 4 falls on the top of the book block 4 on the conveying belt 3 along the movement direction of the conveying belt 3, and finally forms the collated book.

[0047] In the embodiment, as shown, Figure 2 The rack 11 and the placing table 12 are spaced apart along the horizontal direction by a distance, and the stacked book block 4 on the placing table 12 extends from the edge of the placing table 12 close to the rack 11 to abut against the rack 11.

[0048] The paper delivery assembly 13 is located below the placing table 12 and on the side close to the edge of the placing table 12 between the placing table 12 and the rack 11, and the paper delivery assembly 13 close to the placing table 12 facilitates the rapid contact with the bottom book block 4 on the placing table 12 and the extraction of the book block 4.

[0049] The lifting assembly 15 is located on the upper surface of the placing table 12, the stacked book block 4 on the placing table 12 is placed in the lifting assembly 15, and the lifting assembly 15 lifts the stacked book block 4 to cooperate with the extraction of the book block 4 by the paper delivery assembly 13.

[0050] As shown, Figure 3 In the embodiment, the ejector pin 111 is fixed on the rack 11 at a position horizontally flush with the placing table 12 and faces the placing table 12, the tip of the ejector pin 111 points to the placing table 12, and the ejector pin 111 abuts below the bottom book block 4, and when the bottom book block 4 is driven by the paper delivery assembly 13 to bend downward, the ejector pin 111 abuts on the book block above the bottom book block 4, and the ejector pin 111 prevents the book block above the bottom book block 4 from being taken off together when the bottom book block 4 is extracted by suction.

[0051] In this embodiment, the paper output assembly 13 includes a roller assembly 131, two suction nozzles 132 and a rotating mechanism 133. The roller assembly 131 and the suction nozzles 132 are both located below the edge of the placement platform 12 near the frame 11. The suction nozzles 132 are connected to the lower surface of the placement platform 12 through the rotating mechanism 133.

[0052] Specifically, a roller assembly 131 is formed by three rollers 1311 and a rotating shaft 1313. The rotating shaft 1313 connects the three rollers 1311 along the central axis of the rollers 1311. The three disc-shaped rollers 1311 are driven to rotate coaxially through the rotating shaft 1313. The three rollers 1311 are spaced at the same distance on the rotating shaft 1313.

[0053] Each roller 1311 has a friction element 1312 fixed on its circumferential surface. The friction element 1312 is a low-grit sandpaper fixed on the circumferential surface of the roller 1311. The low-grit sandpaper has a certain friction force and can provide a certain friction force to extract the book 4 when the roller 1311 contacts the book 4 without causing friction damage to the surface of the book 4.

[0054] like Figure 4 As shown, in this embodiment, a suction nozzle 132 corresponds to a rotating mechanism 133 connected to the bottom of the placement platform 12.

[0055] Specifically, a rotating mechanism 133 includes a connecting block 1331 and a rotating rod 1132. The connecting block 1331 is a square block, one end of which is fixed to the lower surface of the placement platform 12. The end of the connecting block 1331 away from the placement platform 12 is hinged to the rotating rod 1132, which is a long strip plate.

[0056] The rotating rod 1132 is driven by a motor to rotate around the hinge point with the connecting block 1331. The end of the rotating rod 1132 away from the connecting block 1331 is fixedly connected to the suction nozzle 132. When the rotating rod 1132 rotates, it drives the suction nozzle 132 to reciprocate along an arc trajectory to adsorb and extract the bottom booklet 4.

[0057] In this embodiment, the suction nozzle 132 is located between any two adjacent rollers 1311 in a roller group 131. The suction nozzle 132 is an arc-shaped rod fixed to the bottom end of the rotating rod 1132, and the suction force is maintained inside the arc-shaped rod.

[0058] The top of the suction nozzle 132 is a compression head 1321 made of elastic material. The suction nozzle 132 is used to suck and extract the bottommost book block 4 on the placement table 12 through the compression head 1321. When not in the suction state, the suction nozzle 132 is below the placement table 12, and the compression head 1321 is below the horizontal plane of the placement table 12. When in the suction state, the suction nozzle 132 rotates clockwise along an arc trajectory upward at the edge of the placement table 12, so that the top end of the compression head 1321 reaches the level of the plane of the placement table 12. At this time, the compression head 1321 abuts against the lower surface of the bottommost book block 4 to suck the book block 4. When the suction nozzle 132 rotates counterclockwise along an arc trajectory downward to reset, the compression head 1321 drives the part of the bottom book block 4 beyond the edge of the placement table 12 to be close to the roller set 131 to be bent.

[0059] Two baffles 112 are fixed below the placement table 12 at a position lower than the plane of the placement table 12. The baffles 112 are square long plates inclined in the vertical direction. The baffles 112 resist the book block 4 extracted by the roller set 131. Because the suction nozzle 132 sucks the side edge of the book block 4 exposed on the placement table 12, when the roller drives the book block 4 to rotate, the center of gravity of the book block 4 will deviate. The mass on the side of the book block 4 away from the baffle 112 is larger, preventing the inertia of the book block 4 driven by the roller set 131 from being too large to fall into the lower transmission belt for subsequent book block 4 stacking.

[0060] The upper end of the baffle 112 is fixed to the rack 11 and is higher than the height of the rotating shaft 1313 of the roller set 131, so that the book block 4 extracted and slid out of the roller set 131 can abut against the baffle 112 to prevent the book block 4 from slipping off.

[0061] The lower end of the baffle 112 is below the roller set 131 in the vertical direction. The lower end of the baffle 112 is inclined toward the roller set 131 in the vertical direction by the rack 11. The lower end of the baffle 112 corresponds to the upper end of the conveyor belt 3, so that the book block 4 slides through the baffle 112 and falls onto the conveyor belt 3.

[0062] In this embodiment, the positioning assembly 14 includes a positioning groove 141, a positioning table 142, and a positioning piece 143. The positioning piece 143 abuts against and positions the stacked book blocks on the placement table 12 to prevent the book blocks from sliding during extraction.

[0063] The positioning groove 141 is a waist-shaped groove opened on the placement table 12. The groove hole penetrates the upper surface of the placement table 12. The positioning groove 141 is opened in the direction of the rack 11.

[0064] The positioning table 142 is composed of an abutting table 1421 and a sliding column 1422. The abutting table 1421 and the sliding column 1422 are an integral structure. The positioning table 142 is perpendicular to the surface of the placement table 12. The positioning table 142 moves toward or away from the rack 11.

[0065] The abutting table 1421 is a square plate perpendicular to the plane of the placing table 12, and the sliding column 1422 is a cylinder 1521 corresponding to the width of the positioning groove 141. The sliding column 1422 is fixed at the bottom end of the abutting table 1421 and penetrates the positioning groove 141, and the sliding column 1422 moves in the positioning groove 141.

[0066] The end of the sliding column 1422 away from the abutting table 1421 is provided with a thread, and the sliding column 1422 penetrates the thread below the positioning groove 141 to fix the position of the positioning table 142 with a bolt. When the positioning table 142 is fixed, the face of the abutting table 1421 close to the rack 11 abuts against one side of the stacked book.

[0067] The positioning member 143 is two L-shaped positioning plates fixed on the upper end of the rack 11, and the L-shaped openings of the two positioning plates are oppositely arranged, and the included angle of the two openings corresponds to the corner angle of the book at the edge of the placing table 12. The corner angles at both ends of the book are positioned and abutted.

[0068] The two positioning plates and the abutting plate abut and position the two corner angles of one side and the opposite side of the stacked book. The abutting plate is adjusted by sliding in the positioning groove 141 through the sliding column 1422 to correspond to books of different widths.

[0069] In this embodiment, the collating mechanism 1 further comprises a detection camera 16, which is used to shoot the state of the book on the roller 1311.

[0070] The detection camera 16 is fixed on the rack 11 and located between the two positioning plates. The shooting angle of the detection camera 16 is directed to the roller surface of the plurality of rollers 1311 in the roller set 131. When the book contacts the roller surface of the roller 1311, the detection camera 16 shoots the book. If the shooting result shows that the shooting book surface shows different content from the set content, it is displayed as an abnormal state. If there is no suction nozzle 132 in the shooting picture during detection, it is displayed as an abnormal state. If the shooting picture shows that the book 4 is not flat, it may be that the bottommost book 4 drives the upper books 4 to slide, which is displayed as an abnormal state. The above states all issue an abnormal signal and stop the equipment running.

[0071] In this embodiment, as shown in Figure 5 The lifting assembly 15 comprises a frame 151 and a vibrator 154. The frame 151 is located on the upper surface of the placing table 12 and the stacked book is placed in the frame 151. The vibrator 154 is fixed on one side of the frame 151.

[0072] The frame 151 is formed by combining the surrounding part 152 and the lifting part 153. The surrounding part 152 is composed of six cylinders 1521 perpendicular to the placement platform 12 and a connecting plate 1522. Two of the six cylinders 1521 are fixed on one side to form a concave surrounding part with an opening on one side. The connecting plate 1522 is located on the outside of the concave surrounding part and fixes the six cylinders 1521 in place.

[0073] The lifting part 153 is composed of horizontal plates 1531 arranged in the horizontal direction, which extend from one end of each cylinder 1521 near the placement platform 12 toward the center of the concave enclosure. The six horizontal plates 1531 correspond to the six cylinders 1521, and the bottom of the stacked book pieces is placed on the plane formed by the horizontal plates 1531.

[0074] The vibrator 154 is fixed on one side of the connecting plate 1522.

[0075] like Figure 6 As shown, in operation, the vibrator 154 and the suction nozzle 132 are electrically connected via an electrical signal. When extracting the bottom layer of book stickers, the suction nozzle 132 moves towards the book stickers. When the compression head 1321 on the suction nozzle 132 picks up the book stickers, a signal is generated on the signal device on the suction nozzle 132. The first signal is transmitted to the signal device on the vibrator 154. Upon receiving the first signal, the vibrator 154 vibrates, causing the frame 151 to vibrate, resulting in a momentary, minute vibration of the book stickers accumulated inside the frame 151. The pressure on the bottommost book piece is reduced by moving upwards. When the vibrator 154 vibrates, the suction nozzle 132 drives the bottommost book piece 4 to contact the roller 1311. The friction element 1312 on the surface of the roller 1311 is used to extract the bottommost book piece. When the suction nozzle 132 drives the bottommost book piece 4 to fully adhere to the roller so that the bottommost book piece 4 is discharged, the suction nozzle 132 rotates counterclockwise in the opposite direction to return to the initial state, adheres to the new bottommost book piece 4, and sends out the first signal again.

[0076] like Figure 7 As shown, this embodiment also includes a sorting mechanism 2, which is located at the output end of the conveyor belt 3. The conveyor belt 3 delivers the book formed by the book stickers of different contents that have fallen from multiple collating mechanisms 1 to the sorting mechanism 2.

[0082] Embodiment 2:

[0083] In this embodiment, as shown in Figures 9-10 The lifting assembly 15 includes two shift forks 155 and two cylinders 156, the cylinders 156 are arranged on the rack 11, one end of the shift fork 155 is hinged to the rack 11, and the hinge point is located above the cylinder 156, the end of the shift fork 155 far from the hinge point is hinged to the output end of the cylinder 156, and in this embodiment, the midpoint of the shift fork 155 along the length direction of the shift fork 155 is hinged to the output end of the cylinder 156, and the cylinder 156 drives the shift fork 155 to rotate around the hinge point of the shift fork 155 and the rack 11.

[0084] The shift fork 155 is a long strip-shaped square plate, and the length of the square plate is less than the distance between the rack 11 and the edge of the placement table 12.

[0085] The cylinder 156 pushes the fork 155, causing the fork 155 to rotate along an arc trajectory around the hinge point with the frame 11. The rotation direction of the fork 155 is opposite to the movement direction of the suction nozzle 132. When the suction nozzle 132 rotates downward counterclockwise, the cylinder 156 pushes the fork 155 upward counterclockwise around the hinge point with the frame 11. When the suction nozzle 132 rotates upward clockwise, the cylinder 156 retracts, causing the fork 155 to rotate downward clockwise around the hinge point with the frame 11. The fork 155 and the suction nozzle 132 intersect during rotation. The hinge point between the fork 155 and the frame 11 is lower than the horizontal plane of the placement platform 12 in the horizontal direction. When the cylinder 156 pushes the fork 155 to the highest point, the highest point of the fork 155 is higher than the hinge point and also higher than the horizontal plane of the placement platform 12. The fork 155 lifts the bottom of the book at the highest point.

[0086] A signal device is installed on the cylinder 156, through which the cylinder 156 and the suction nozzle 132 are electrically connected.

[0087] like Figure 11 As shown, when the suction nozzle 132 adsorbs the bottom book piece 4, it moves towards the book piece. When the compression head 1321 on the suction nozzle 132 adsorbs the bottom book piece 4 and bends it towards the roller 1311, the signal device on the suction nozzle 132 generates a second signal. The second signal is transmitted to the signal device on the cylinder 156. When the cylinder 156 receives the second signal, it pushes the fork 155 to rotate upward. When the fork 155 rotates upward, it intersects with the book piece 4 bent downward by the suction nozzle 132, and the fork 155 contacts the bottom book piece. After the book piece 4 above the book piece 4, the cylinder 156 reaches its maximum stroke, causing the fork 155 to move to its highest point, lifting the stacked book pieces 4 above. At the instant the fork 155 lifts the book piece 4 above, the bottom book piece 4 is pulled away from the surface of the contact roller 1311 by the roller 1311. When the suction nozzle 132 rotates to its lowest point, a third signal is generated and transmitted to the signal device of the cylinder 156. The cylinder 156 retracts, driving the fork 155 to rotate downward to reset. When the suction nozzle 132 rotates upward again to absorb the bottom book piece 4, a signal is generated to perform reciprocating motion.

[0090] The moving groove 21 is a U-shaped groove, and the inner surface of the moving groove 21 is smooth to prevent friction from hindering the movement of the books or damaging the books.

[0091] The sliding baffle 22 is an inclined square plate connected to one side of the moving groove 21, the lower end of the long side of the sliding baffle 22 is close to one side of the moving groove 21, the end of the sliding baffle 22 close to the conveying belt 3 tends to be horizontal, the end of the sliding baffle 22 away from the conveying belt 3 tends to be vertical, there is an angle difference between the two ends of the sliding baffle 22 to form a twist, the horizontal end of the sliding baffle 22 makes the books transferred from the conveying belt 3 to the sliding baffle 22 stable and not scattered, and the books are changed from horizontal placement to vertical placement to facilitate subsequent processing.

[0092] There is a gap between the sliding baffle 22 and the moving groove 21, and the push rod 23 passes through the gap, the books fall from the conveying belt 3 to the moving groove 21 and abut against the sliding baffle 22, and are moved by the push rod 23.

[0093] The push rod 23 is a rod perpendicular to the baffle 112, the push rod 23 is in the gap between the sliding baffle 22 and the moving groove 21, a chain conveying belt 24 is arranged on the side of the sliding baffle 22 away from the moving groove 21, a plurality of push rods 23 are fixed on the chain conveying belt 24 at the same interval, the push rod 23 extends from the gap between the sliding baffle 22 and the moving groove 21 and moves along the long side of the sliding baffle 22 in the gap, the push rod 23 pushes the books falling from the conveying belt 3 to the sliding baffle 22 and the moving groove 21, and aligns the edges of the books by pushing the books.
