[0043] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0044] This invention discloses an accumulation conveying device, with reference to Figure 1 and Figure 2 As shown, the system includes a frame 1, a blocking mechanism 2, a tray 3, a buffer mechanism 4, a conveying and turning mechanism 5, a tensioning and lubrication mechanism 6, and an overload alarm mechanism 7. In this embodiment, four blocking mechanisms 2 are provided, located at the loading position, unloading position, waiting position, and conveyor belt position, respectively. The loading and unloading positions can be operated manually or by a robot. The blocking mechanisms 2 are used for blocking and positioning the tray. The buffer mechanism 4 is located at the two end tray turning start positions and is used for buffering before the conveying and turning mechanism 5 is coupled with the tray 3. The tensioning and lubrication mechanism 6 is located in the middle of the conveying equipment and is used to adaptively adjust the chain tension and lubricate the chain. The overload alarm mechanism 7 is located on the drive shaft and mainly protects the motor and chain, preventing motor burnout, chain breakage, etc., caused by excessive load or jamming, which could lead to shutdown and safety accidents.

[0045] Reference Figure 3-4As shown, the frame 1 includes aluminum profiles 1001, guide rails 1002, tracks 1003, support plates 1004, protective covers 1005, and brackets 1006. The support plate 1004 is composed of several components, with two aluminum profiles 1001 mounted on its upper end, distributed at the left and right ends, and two aluminum profiles 1001 mounted on its lower end, also distributed at the left and right ends. Two guide rail 1002 mounting slots are provided on the end faces of the aluminum profiles 1001, allowing the guide rails 1002 to be placed in the two mounting slots of the four aluminum profiles 1001, enabling the tray 3 to move in one direction. In this embodiment, the cross-section of the aluminum profiles 1001 adopts an asymmetric variable stiffness structure, forming a mechanical property of being rigid at the top and flexible at the bottom. It has X-shaped cross reinforcing ribs inside, forming a triangular stable structure. The mounting slots of the guide rails 1002 and the aluminum profiles 1001 adopt a dovetail design. The interference fit and hydraulic expansion process are used during installation. Axial pressure is applied to both ends of the guide rail 1002 to induce slight plastic deformation and completely fill the gap in the mounting groove. This structure eliminates the stress concentration problem of traditional screw fixing and extends service life. The track 1003 is installed on the upper and lower ends of the support plate 1004. The track 1003 adopts a segmented structure with corrugated expansion joints between the segments. When the temperature changes, the track can expand freely at the expansion joints to avoid track deformation caused by thermal stress. It is used to install the chain and guide the chain. The bracket 1006 consists of several parts, mainly located at the left and right ends of the aluminum profile. The lower part has an adjustable mechanism for adjusting the flatness of the equipment. The protective cover 1005 is placed on both sides of the track 1003 at the front and rear ends for personnel safety and to prevent accidental contact.

[0046] Reference Figure 5As shown, the blocking mechanism 2 includes a mounting plate 2001, connecting block 1 2002, blocking wheels 2003, telescopic pins 2004, rotating seats 2005, bearing seats 2006, sensor 1 2007, connecting bracket 1 2008, connector 2009, cylinder 2010, mounting base 2011, connecting rod 2012, connecting bracket 2013, and sensor 2 2014. Two connecting blocks 1 2002 are respectively installed on the left and right sides of the mounting plate 2001 and connected to the aluminum profile 1001 on the frame 1. Four bearing seats 2006 are respectively placed on the left, right, front, and rear sides of the mounting plate 2001. Two rotating seats 2005 are respectively placed in the four bearing seats 2006. Four blocking wheels 2004... 03 is placed on two rotating seats 2005; two telescopic pins 2004 are placed on two rotating seats 2005; connecting bracket 1 2008 is placed at the lower end of mounting plate 2001; connector 2009 is installed on the piston rod of cylinder 2010; the tail end of cylinder 2010 is connected to mounting seat 2011; mounting seat 2011 is placed at the lower end of mounting plate 2001; connecting rod 2012 is installed on connector 2009; two sensors 1 2007 are respectively installed on connecting bracket 1 2008 to detect the extension and retraction state of cylinder 2010; connecting bracket 2 2013 is placed at the upper end of mounting plate 2001; sensor 2 2014 is installed on connecting bracket 2 2013 to detect whether tray 3 is in place.

[0047] The working principle of the blocking mechanism 2 is as follows: the cylinder 2010 is connected to the connector 2009, the connector 2009 is connected to the connecting rod 2012, and the connecting rod 2012 is connected to the rotating seats 2005 at both ends. The rotating seat 2005 is equipped with two blocking wheels 2003 and a telescopic pin 2004. When the pallet 3 passes through, the telescopic pin 2004 retracts the blocking wheel 2003 to block the pallet 3, and the telescopic pin 2004 rises to prevent the pallet 3 from retracting. This allows for more precise control of the position of the pallet 3. When the pallet 3 needs to be released, the piston rod of the cylinder 2010 extends, driving the connector 2009 to drive the connecting rod 2012 to move. The movement of the connecting rod 2012 drives the rotating seat 2005 to rotate, thus releasing the pallet 3. Since the blocking wheel 2003 is fixed on the rotating seat 2005, a blocking wheel 2003 is provided at the other end of the rotating seat 2005 to prevent the pallet 3 from retracting during release.

[0048] Reference Figure 6-7As shown, the tray 3 consists of a panel 3001, rollers 3002, pulleys 3003, a rotating traction block 3004, a blocking block 3005, a first buffer pad 3006, a second buffer pad 3007, a damping traction mechanism 3008, and a first connecting plate 3009. A rotating traction block 3004 is installed at each end of the upper surface of the panel 3001; a first connecting plate 3009 is installed at the upper end of the panel 3001; two rollers 3002 are installed on one side of each rotating traction block 3004, and a pulley 3003 is installed on one of the rollers 3002; a blocking block 3005 is installed on the other side of the rotating traction block 3004; a first buffer pad 3006 and a second buffer pad 3007 are installed at the upper and lower ends of the first connecting plate 3009; the damping traction mechanism 3008 is installed on the side of the first connecting plate 3009; the rollers 3002 are provided with U-shaped grooves for engaging with the guide rail 1002 in the frame 1. The damping traction mechanism 3008 consists of a self-locking nut 30081, a connecting plate 2 30082, a gasket 30083, a shaft 30084, a pressure plate 1 30085, a spring 1 30086, a friction plate 30087, a pressure plate 2 30088, a traction sprocket 30089, an oil-free gasket 1 300810, an oil-free gasket 2 300811, a connecting plate 3 300812, and a pin 300813. The traction sprocket 30089 is fitted into the shaft 30084; the first oilless gasket 300810 is installed on the side of the traction sprocket 30089; the friction plate 30087 is placed on the other side of the traction sprocket 30089; the second pressure plate 30088 is placed on the side of the friction plate 30087; the pin 300813 is installed into the hole of the second pressure plate 30088 and placed in the groove of the shaft 30084; the pin 300813 is installed into the hole of the first pressure plate 30085; the first spring 30086 is fitted into the shaft 30084 and placed on the second pressure plate 30085. 088 Side view; Pressure plate 30085 is placed on one side of spring 30086, while pin 300813 is placed in the groove of shaft 30084; gasket 30083 is placed on the side of pressure plate 30085; oil-free gasket 300811 is installed on one side of connecting plate 3009; shaft 30084 is installed into the hole of connecting plate 3009; connecting plate 300812 is installed on the other side of connecting plate 3009 and fixed to shaft 30084; self-locking nut 30081 locks pressure plate 30085.The working principle of pallet 3 is as follows: During the linear motion of pallet 3, the sprocket drives the traction sprocket 30089 to move, and friction drives the pallet 3 to move linearly. During the flipping process, the damping traction mechanism 3008 makes the pallet 3 run smoothly. The damping traction mechanism 3008 mainly exerts force on the pressure plate 30088 through the spring 30086. The pressure plate 30088 transmits the force to the friction plate 30087, and the friction plate 30087 presses the traction sprocket 30089. During the flipping process, the traction sprocket 30089 is no longer driven, and the overall flipping is mainly carried out by the conveying flipping mechanism 5. The groove and shim 30083 set in the shaft 30084 are used to adjust the preload of the spring 30086.

[0049] Reference Figure 8 As shown, the buffer mechanism 4 includes a buffer block 4001, a second spring 4002, a connecting seat 4003, a limiting block 4004, and a rotating shaft 4005. The buffer block 4001 is connected to the connecting seat 4003 via the rotating shaft 4005. The upper and lower ends of the second spring 4002 are respectively placed on the buffer block 4001 and the connecting seat 4003. The limiting block 4004 is connected to the connecting seat 4003. The connecting seat 4003 is connected to the conveying and flipping mechanism 5.

[0050] The working principle of the buffer mechanism 4 is that the blocking mechanism 2 releases the pallet 3, the pulley 3003 on the pallet 3 contacts the buffer block 4001, and the buffer block 4001 is provided with a buffer arc groove. When the pallet 3 is coupled with the conveying and flipping mechanism 5, it drives the pallet 3 to move, and the buffer block 4001 rotates around the rotating shaft 4005. The buffer block 4001 compresses the second spring 4002, the pulley 3003 in the pallet 3 is displaced, the second spring 4002 returns to its original position, and the buffer block 4001 rotates around the rotating shaft 4005. The limit block 4004 restricts the buffer block 4001 from returning to its original position.

[0051] Reference Figure 9-11 As shown, the conveying and turning mechanism 5 includes a motor 5001, a guide disk 1 5002, a drive shaft 5003, a drive sprocket 5004, a coupling mechanism 5005, a guide disk 2 5006, a sprocket 5007, a driven shaft 5008, and a driven sprocket 5009.

The coupling mechanism 5005 consists of a coupling disc 50051 and coupling pins 50052. Six coupling pins 50052 are evenly installed on the coupling disc 50051.

[0053] The working principle of the conveying and flipping mechanism 5 is that the motor 5001 rotates, driving the active sprocket 5004, which in turn drives the driven sprocket 5009 to rotate through the sprocket 5007, thereby driving the pallet 3 to move in a straight line; the rotation of the motor 5001 drives the coupling mechanism 5005 to rotate, and the coupling pin 50052 on the coupling mechanism 5005 is coupled with the rotating traction block 3004 on the pallet 3, thereby driving the rotation of the pallet 3.

[0054] In this embodiment, an energy recovery module, including a permanent magnet generator and a supercapacitor, is installed on the driven shaft 5008 of the conveying and flipping mechanism 5. When the tray 3 moves downward or brakes, the motor 5001 is in the power generation state. The energy recovery module stores the regenerated electrical energy in the supercapacitor for equipment startup and auxiliary power supply, thereby achieving energy saving.

[0055] Reference Figure 12-14As shown, the tensioning and lubrication mechanism 6 includes an oil receiving groove 6001, a chain tensioning assembly 6002, an adjusting shaft 6003, an adjusting nut 6004, a spring 6005, a lubrication block 6006, an oil pipe 6007, an oil can 6008, a connecting plate 6009, a connecting block 6010, a sensor 6011, a scale 6012, a pointer 6013, and a connecting plate 6014; the tensioning and lubrication mechanism 6 is composed of a sprocket 60021, a brush 60022, a sprocket 60023, a sprocket 60024, a sprocket 60025, and a sprocket 60026. Sprockets 60021, 60023, 60025, and 60026 are installed on one side of connecting plate 6014; scale 6012 is installed on the other side of connecting plate 6014; adjusting shaft 6003 is placed on one side of connecting plate 6014; sprocket 60024 is connected to adjusting shaft 6003; pointer 6013 is installed on one end of sprocket 60024; brush 60022 contacts sprocket 60023 and is placed on one side of connecting plate 6014; connecting plate 6009 is installed on one side of sprockets 60021, 60023, 60025, and 60026; spring 6005... An auxiliary pneumatic cylinder is added to the spring 6005 and fitted onto the adjusting shaft 6003. The pneumatic cylinder is connected in parallel with the adjusting shaft 6003, and the air pressure is controlled by a proportional valve. During normal operation, the spring 6005 provides basic tension. When the chain extends or retracts rapidly, the pneumatic cylinder responds quickly according to the acceleration signal to provide instantaneous compensation tension and prevent the chain from jumping. The adjusting nut 6004 is placed on the adjusting shaft 6003. The connecting block 6010 is installed on the connecting plate 6009 and has a waist-shaped hole for easy adjustment. Two sensors 6011 are installed on the connecting block 6010. The sensors 6011 not only monitor the tension position but also record the change curve of the tension position over time. The control system establishes a chain wear prediction model based on historical data and uses an exponential smoothing algorithm to predict the remaining life. When it is predicted that the chain will reach the wear limit within a set time, an early warning is automatically issued to achieve predictive maintenance and avoid sudden failures. The lubrication block 6006 is installed on the end face of the connecting plate 6014 and connected to the brush 60022. One end of the oil pipe 6007 is connected to the lubrication block 6006, and the other end is connected to the oil can 6008. The oil can 6008 is installed on the aluminum profile 1001. The tensioning lubrication mechanism 6 is installed on the upper track 1003. The oil receiving groove 6001 is installed on the lower track 1003. An ultrasonic transducer can be installed at the bottom of the oil receiving groove 6001. It is activated periodically to generate ultrasonic waves to emulsify and discharge the deposited waste oil, preventing sludge from clogging the oil outlet. The inner wall of the oil receiving groove 6001 is coated with an oleophobic coating, so the waste oil does not easily adhere and automatically flows to the oil outlet.

[0056] The working principle of the tensioning and lubrication mechanism 6 is to adjust the chain 5007 according to... Figure 14The chain 5007 is threaded out in the manner shown. This arrangement primarily ensures the tension of the chain 5007 and reduces its wear. The spring force of the spring 6005 is adjusted by adjusting the nut 6004. Two sensors 6011 are installed, one for adjusting the range and also serving as an alarm. The pointer 6013 and scale 6012 facilitate adjustment during on-site installation. The oil can 6008 outputs oil through the oil pipe 6007 and then through the lubrication block 6006 to the brush 60022. The brush 60022 lubricates the sprocket 60023, thereby lubricating the chain 5007 and ensuring its service life. The oil can 6008 uses a timed oiling method to reduce manual intervention. The oil collection trough 6001 is used to collect waste oil, ensuring the cleanliness of the equipment's appearance.

[0057] Reference Figure 15 As shown, the overload alarm mechanism 7 includes an overload seat 7001, an adjusting seat 7002, an adjusting block 7003, an adjusting bolt 7004, a spring 7005, and a sensor 7006. The adjusting seat 7002 is installed on the guide plate 5002; the overload seat 7001 is installed on the motor 5001; the adjusting block 7003 is placed on the adjusting seat 7002; the spring 7005 is placed on the adjusting block 7003; the sensor 7006 is installed on the adjusting seat 7002; and the adjusting bolt 7004 is installed on the adjusting seat 7002 and passes through the adjusting block 7003 and the spring 7005.

[0058] The overload alarm mechanism 7 works as follows: when the load on tray 3 is too high or chain 5007 is jammed, motor 5001 vibrates, causing overload seat 7001 to displace, spring 7005 to compress, sensor 7006 to receive no signal, the equipment alarms, and stops operating. Adjusting bolt 7004 is used to adjust the preload of spring 7005. The preload plays a crucial role in the overload alarm mechanism 7; if it is too high, overload seat 7001 cannot displace, and the alarm function cannot be triggered; if it is too low, the alarm function triggers frequently. A shape memory alloy spring is installed between adjusting block 7003 and adjusting seat 7002. When overload causes spring 7005 to compress, the shape memory alloy spring automatically restores its shape when the motor heats up, pushing adjusting block 7003 and overload seat 7001 back to their original positions without manual intervention. Sensor 7006 is a piezoelectric sensor that generates an electrical signal by utilizing the pressure change when overload seat 7001 contacts adjusting block 7003, requiring no external power supply. Sensor signals are transmitted wirelessly to the control system, completely solving the wiring problem for moving parts. Even if the equipment is powered off, the overload alarm mechanism can still operate independently, achieving fault safety protection. Simultaneously, an inertial mass block is added to the spring 7005. This inertial mass block is connected to the overload seat 7001 via a damping spring. When the equipment is running normally, the inertial mass block moves synchronously with the motor; when jamming occurs, the inertial mass block lags behind the overload seat 7001 due to inertia, resulting in relative displacement and triggering the auxiliary sensor alarm.
