[0031] The collating machine collates the content of the book to form a book core. The qualified book core and the marked book core for waste will be transmitted on the surface of the pallet channel, and the lever pushes the book core forward; the pallet (including the upper chain pallet 24 and the lower chain pallet 26) is used to support the book core and guide the direction of the book core. When the marked book core for waste reaches the upward flap assembly 3 from the pallet channel assembly, the cylinder in the upper flap assembly 3 extends to drive the swing arm to rotate around the fulcrum, so that the upward flap assembly 3 tilts upward, docks the upper and lower conveying belt assemblies 4, and pushes the marked book core for waste into the upper and lower conveying belt assemblies 4. The marked book core for waste is clamped and transmitted to the receiving belt by the upper and lower conveying belt assemblies 4; when the qualified book core reaches the upward flap assembly 3 from the pallet channel assembly 2, the cylinder in the upper flap assembly 3 remains in a retracted state, so that the upward flap assembly 3 and the pallet channel assembly 2 are in the same plane, and the lever continues to push the qualified book core into the next processing unit, and the collating machine uses the above-mentioned waste discharge mechanism to remove the waste book core. The outer inclined bottom plate 27 and the L-shaped inner bottom plate 23 exposed to the outside have a gap in the middle of these two parts. The gap is where the upward flap assembly 3 is installed. On the one hand, the upper flap assembly 3 is in the same plane as the pallet channel assembly, and the lever pushes the qualified book core to continue to move forward; on the other hand, the upper flap assembly 3 is at an inclined angle with the pallet channel assembly 2, docking the upper and lower conveyor belt assemblies 4, and the lever pushes the marked waste book core to enter the upper and lower belts, and the upper and lower belts clamp and remove the problematic book core. The qualified book core and the marked waste book core are moved on the pallet channel assembly and the upward flap assembly 3 by the power of the lever. The chain 211 runs through the collating machine, and a driving sprocket (not shown) is provided at one end of the collating machine, and a driven sprocket (not shown) is provided at the other end of the collating machine. The chain 211 is a closed ring transmission system. A lever is installed equidistantly on the chain 211, and the spacing between each lever is equal.

[0032] In this embodiment, a channel through which a lever passes is provided between the pallet channel assembly 2 and the upward flap assembly 3. The lever is pulled by the chain 211. There is a book core in each lever interval, which may be a qualified book core or a book core marked for waste discharge. The lever 29 is used to push the book core on the pallet. The pallet channel assembly is provided with a support bar of an upper lever chain and a support bar of a lower lever chain, both of which play the role of supporting and guiding the chain 211. The lower chain support plate 24, the middle pad 25, the upper chain support plate 26, the outer inclined bottom plate 27, the small mounting bracket 28, the lever 29, and the outer mounting pad 210 constitute the chain guide groove of the chain 211. The chain 211 pulls the lever forward from the upper chain support bar and then returns from the lower chain support bar, forming a closed power transmission system. The power of the chain comes from an external servo motor (not shown) installed at one end of the collating machine.

[0033] The pallet channel in the pallet assembly 2 receives the book cores transmitted from the collating station, and these book cores include the book cores marked for waste discharge. The book core is pushed forward by the lever 29 on the outer inclined bottom plate 27. When the book core reaches the notch, the book core marked for waste discharge will be transmitted to the waste discharge assembly and sent out. The qualified book core will continue to be transmitted forward along the pallet by the lever. The outer inclined bottom plate 27 and the L-shaped inner bottom plate 23 form the pallet channel. The lever 29 is fixed on the chain 211, and the lower chain pallet 24, the middle pad 25, and the upper chain pallet 26 are used to install the chain 211, so that the chain 211 will not run out of position, increasing the stability of the chain transmission. The chain 211 is inserted between the waste discharge mechanism and the collating machine, and the driving sprocket and the driven sprocket are respectively arranged at both ends of the collating machine (not shown).

[0034] like Figure 5 and Figure 6 As shown, the upward flap assembly 3 includes a cylinder 31, a driving swing arm 32, a swing support shaft 33, a tight expansion sleeve 34, a pressure cover 35, an intermediate cushion sleeve 36, a long swing arm 37, a short swing arm 38, a pull rod 39, a lower mounting plate 310, an upper mounting plate 311, an oblique mounting block 312, a swing seat 313, a waste exhaust blowing bottom plate 314, a waste exhaust swing bottom plate 315, an inner oblique swing plate 316, and a swing shaft seat 317. One end of the cylinder 31 is mounted on the cylinder mounting plate 14 with a cylinder support shaft, and the cylinder may rotate around the cylinder support shaft. The other end is connected to the driving swing arm 32, and the driving swing arm 32 is fixed on the swing support shaft 33. The swing support shaft 32 passes through the left wall panel 11 and the right wall panel 12 of the frame 1. Bearings are installed at both ends of the shaft and are fixed to the left wall panel 11 and the right wall panel 12 with bearing mounting seats. The long swing arm 37 and the short swing arm 38 are suspended in pairs on the swing support shaft 32 and fixed with a tightening sleeve 34 and a pressure cover 35. Each pair of swing arms is separated by an intermediate cushion sleeve 36, and each pair of swing arms is connected by a pull rod 39. The lower mounting plate installation 310 is fixedly mounted on the top of the bottom mounting seat 16 of the frame 1, and the upper mounting plate 311 is fixedly mounted on the top of the lower mounting plate 310 with an oblique mounting block 312.

The inner oblique swing plate 316 is installed on the support plate 15 of the frame 1 through a swing shaft seat 317. The swing shaft of the swing shaft seat 317 passes through the inner oblique swing plate 316, so that the swing plate can swing up and down.

[0035] The upward flap assembly 3 is installed at the notch of the pallet channel. When the qualified book core reaches the upward flap assembly 3, the cylinder 31 is in a retracted state, the waste discharge swing bottom plate 315 and the outer inclined bottom plate 27 remain in the same plane, and the book core continues to be transported forward to enter the binding machine; when the book core marked for waste discharge reaches the waste discharge swing bottom plate 315, the cylinder 31 is in an extended state, the waste discharge swing bottom plate 315 will flip up, and the book core marked for waste discharge will be transported upward along the bottom plate 315, and the power comes from the lever. After the book core marked for waste discharge enters the upper and lower belt clamping, the power comes from the driving motor of the upper and lower belts. The lower mounting plate 310, the upper mounting plate 311, the oblique mounting block 312, the swing seat 313, the waste discharge air blowing bottom plate 314, the waste discharge swing bottom plate 315, the inner oblique swing plate 316, and the swing shaft seat 317 are combined into a small assembly. The waste discharge swing bottom plate 315 is flipped by pulling the pull rod 39 up and down. When the bottom plate 315 is flipped up, it is used to convey the book blocks marked for waste discharge. When the bottom plate 315 returns to the same plane as the outer oblique bottom plate 27, it is used to convey qualified book blocks. In this embodiment, the swing support shaft 33 of the upward flip plate assembly links the long swing arm 37 and the short swing arm 38. The actuator can be a cylinder connecting rod, or a servo motor that drives the swing support shaft 33 around the fulcrum offset angle through a synchronous belt or chain. In this embodiment, the cylinder is used as the power as an example.

[0036] like Figure 7 , Figure 8 and Fig. 9As shown, the upper and lower conveyor belt assembly 4 includes a left wall panel 41, a right wall panel 42, a motor 43, an upper belt driving roller 44, a gear shaft 45, a belt 46, an upper belt wall panel 47, a conveyor belt cylinder 48, a tensioning wheel swing arm 49, a pulley 410, a tensioning pulley 411, a lower belt driving roller 412, a belt pad 413, a lower belt driven pulley 414, a spring 415, a hanging plate 416, and a column 417. The left wall panel 41 and the right wall panel 42 are fixed on the columns 417 installed on both sides of the frame 1 in parallel relative to each other; the motor 43 is fixedly installed on the left column 417 installed near the book output end; the upper belt driving roller 44 passes through the left wall panel 41 and the right wall panel 42, and is equipped with bearings and bearing seats at both ends. The bearing seats are respectively fixed on the left and right side wall panels, and the power is provided by the motor 43; the two upper belt wall panels 47 are connected by hexagonal studs and installed on the hanging plate 416 passed by the gear shaft 45; the transmission belt cylinder 48 is suspended in parallel front and back on the left wall panel 41 On the U-shaped support beam between the left and right wall panels 42, the other ends of the two conveyor belt cylinders 48 respectively pull the two ends of the two upper belt wall panels 47, and adjust the distance between the upper belt wall panels 47 and the belt pad 413 by the extension and contraction of the cylinders; the tension wheel swing arm 49 is arranged and installed on the two upper belt wall panels 47, and is pulled by a spring 415 to provide tension; the lower belt active roller 412 is also installed between the left wall panel 41 and the right wall panel 42; the belt pad 413 is fixed between the left wall panel 41 and the right wall panel 42 and is located below the tension wheel swing arm 49.

[0037] In this embodiment, all components are connected by screws and various standard parts to form a complete mechanical structure.

[0038] In the book binding production, the workstations of the pagination machine sequentially place stickers at the same lever interval, so that multiple book stickers are arranged in order to form a book core. The lever 5 exists both in the pagination machine and in the waste discharge mechanism, located between the outer inclined bottom plate 27 and the L-shaped inner bottom plate 23, and fixed on the chain 211. The flat book core is pushed into the entire device from the book inlet end, and passes through the pallet channel assembly 2 in turn. The lever chain 51 runs through the pagination machine. The waste discharge mechanism is the part connected to the rear end of the pagination machine. The book core marked for waste discharge is removed by the waste discharge mechanism and enters the upper and lower conveyor belt assembly 4. The book core marked for waste discharge is clamped and conveyed to the collection belt by the upper and lower belts. The qualified book core passes through the upward flap assembly 3, and the flap remains horizontal. The qualified book core is transported forward along the pallet channel assembly 2 to the book outlet.

[0039] Lever 5 Fig.10 As shown, it is driven by a lever chain 51 that runs through the pagination machine, and the bottom of each lever 5 is fixed to the chain link 53 of the chain 51 by a latch 52.

[0040] When the book block marked for waste discharge is transported to the waste discharge swinging bottom plate 315 and the inner inclined swinging plate 316 of the upward flip plate assembly 3, the cylinder 31 extends under the control of the solenoid valve, driving the swing arm 32 to rotate around the fulcrum, so that the waste discharge swinging bottom plate 315 and the inner inclined swinging plate 316 are tilted upward and docked with the upper and lower conveying belt assembly 4, and the book block marked for waste discharge enters the upper and lower belt clamping transmission. The upper and lower belts are powered by independent motors. The upper and lower belts convey the book block and push up the tension wheel swing arm 49. The tension wheel swing arm 49 is spring-loaded. The elastic tension of 415 presses the book downward, so that the marked book for waste discharge passes through the upper and lower conveying belt assembly 4 quickly and smoothly under the drive of belt 46, and is transmitted to the collecting belt for sorting; after the marked book for waste discharge enters the upper and lower conveying belt assembly 4, the cylinder 31 of the upward flap assembly 3 retracts under the control of the electromagnetic valve, and the waste discharge swing bottom plate 315 and the inner inclined swing plate 316 flip downward and return to the horizontal position of the pallet in the pallet channel assembly 2, so that the qualified book core can continue to be transported forward along the pallet channel. The upward flap removal and waste discharge method can make the book core be removed smoothly and quickly, and this upward flap removal method can effectively avoid the occurrence of book jams, effectively reduce the damage of book labels, and avoid waste of book labels. Furthermore, the waste discharge mechanism of the upward flap removal adopts the method of flipping the flap upward, and the removal direction of the marked book core for waste discharge is consistent with the movement direction of the book core, and the removal efficiency is higher.

[0041] In this embodiment, the power source of the upper and lower conveyor belt assemblies is an external motor, and the transmission system is simpler and convenient to maintain. The book core lies flat on the pallet channel for transmission, and the book core has a wide contact surface, which can prevent the book from curling and wrinkling. Especially for book cores with light paper weight, soft and thin paper, it can effectively reduce the damage of the book stickers and avoid waste of book stickers. The horizontal collection operation is more convenient. When working, the two cylinders of the upper and lower belt assemblies remain in an extended state, and the upper belt is attached to the lower belt. The upper and lower belts can be removed upward by the book core marked for waste discharge.
