Description

Technical Field

[0001] This invention relates to the field of packaging technology, specifically to a stable and efficient automatic bottle counter and its operating method. Background Technology

[0002] Existing automated palletizing equipment generally uses a conveyor platform for direct transport, resulting in a large accumulation of empty bottles on the platform, which easily leads to bottle tipping. After tipping, manual handling is required, which can easily cause secondary contamination and cannot completely eliminate manual labor. To solve this technical problem, Chinese Patent Application No. 202120759967.3, published on November 30, 2021, discloses a fully automatic and efficient bottle stacking machine, including a bottle feeding mechanism, an automatic arrangement and pushing mechanism, an empty bottle sorting conveyor platform, a bottle holding and moving mechanism, a layer partition storage bin, a bottle stacking mechanism, a bottom tray storage bin, and a frame. The bottle feeding mechanism... The bottle feeding mechanism, automatic sorting and pushing mechanism, empty bottle sorting conveyor platform, and bottle carrying and moving mechanism are all mounted on the frame. The bottle feeding mechanism has a bottle inlet conveyor, the automatic sorting and pushing mechanism has a bottle pusher, the bottle pusher has a bottle inlet mechanism fixed at its lower end and a lifting mechanism at its side end, and the bottle inlet mechanism is arranged parallel to the bottle inlet conveyor. The empty bottle sorting conveyor platform has an automatic sorting and pushing mechanism on one side and a bottle carrying and moving mechanism on the other side. The bottle stacking mechanism is located below the bottle carrying and moving mechanism. The bottle stacking mechanism has a base plate storage compartment on one side for conveying base plates to the bottle stacking mechanism, and a partition plate on the other side for providing layer partitions to the bottle stacking mechanism. A partitioned storage compartment.

[0003] However, in the aforementioned literature, when the bottle-pushing cylinder moves the entire bottle-feeding mechanism to the empty bottle sorting conveyor platform, the bottles are prone to tilting or tipping over during the pushing process. This can easily cause pauses during operation due to the bottles tilting or tipping over, resulting in low efficiency of the entire production line. In addition, the bottle-feeding mechanism may touch the bottle mouth, causing secondary contamination. Furthermore, the width of the bottle-feeding mechanism is fixed before the bottles enter the bottle-feeding tunnel, making it impossible to adjust the width of the bottle-feeding mechanism according to the size of the bottles, resulting in poor reliability. Summary of the Invention

[0004] The purpose of this invention is to provide a stable and efficient automatic bottle stacking device and working method, which can adjust the size of the bottle inlet channel according to the width of the bottle, and at the same time prevent the bottle from tipping over during movement, thereby avoiding interruptions in the operation and achieving high work efficiency.

[0005] This invention provides a stable and efficient automatic bottle-stacking device, comprising a conveying section, a moving section, and a pushing section. The conveying section includes a bottle inlet channel, a diversion device, and two or more diversion channels. The front end of the diversion device is connected to the bottle inlet channel, and the rear end of the diversion device is connected to the inlet end of the diversion channel. The outlet end of the diversion channel, away from the diversion device, is equipped with a shut-off device and a flow-blocking device. The moving section includes a moving platform frame, a moving device, and a bottle-transferring device. The moving device includes a horizontal moving device, a lifting moving device, and a bottle-transferring device. Both the horizontal moving device and the lifting moving device are fixedly connected to the bottle-transferring device. The translational device moves the bottle transfer device to a position corresponding to the push section on one side. The lifting device moves the bottle transfer device up and down. The bottle transfer device includes a fixed bracket and two or more connecting brackets. The two or more connecting brackets are fixed on the fixed bracket. Two or more bottle guide plates 1 are fixed on one side of the connecting bracket. Two or more parallel bottle guide plates 2 are fixed at the bottom of the fixed bracket. Bottle guide plates 1 are arranged on both sides of bottle guide plates 2. Bottle guide plates 2 slide on the fixed bracket in a direction away from or close to bottle guide plates 1. One end of the connecting bracket is provided with a fixed stop, and the other end of the connecting bracket is provided with a clamping device.

[0006] The above setup includes a bottle inlet channel, a diversion device, and two or more diversion channels in the conveying section. This allows empty bottles to enter the diversion device through the inlet channel and be diverted to different diversion channels for efficient conveying. A shut-off device and a flow-intercepting device are installed at the end of each diversion channel furthest from the diversion device. When the shut-off device is opened, empty bottles located between the shut-off and flow-intercepting devices in the diversion channel are conveyed into the bottle transfer device in the moving section. Simultaneously, the flow-intercepting device intercepts other empty bottles in the diversion channel, achieving a flow-intercepting effect and better controlling the number of empty bottles entering the bottle transfer device, thus increasing conveying efficiency. The bottle transfer device is driven by a lifting and moving mechanism. The system features a lifting mechanism; the second bottle guide plate slides along a fixed support in a direction away from or close to the first bottle guide plate. The distance between the first and second bottle guide plates is adjusted according to the size of the empty bottle. A fixed stop is installed at one end of the connecting support, and a pressing device is installed at the other end. After an empty bottle enters between the first and second bottle guide plates, the fixed stop prevents the first empty bottle entering from the diversion channel from reaching a preset fixed position and then stops it. The pressing device then presses down on the last empty bottle entering from the diversion channel from the side. This ensures a smoother transfer of empty bottles and prevents them from tilting or tipping over, which could lead to contamination of the bottles and affect the efficiency of the transfer operation.

[0007] Furthermore, the horizontal moving device includes a guide rail 1, a moving frame, a drive motor 1, and a transmission shaft. The guide rail 1 is fixed on the moving platform frame. The moving frame is slidably connected to the guide rail 1 via a slider 2. The drive motor 1 is rotatably connected to the transmission shaft. The transmission wheels 1 at both ends of the transmission shaft are connected to the transmission wheels 2 located inside the moving platform frame via a transmission belt. A connecting block is fixed at the bottom of the moving frame, and the connecting block is clamped and fixed on the transmission belt. The lifting moving device includes a drive motor 2, a transmission shaft 2, and two or more lifting frames. The slider 3 fixed on the moving frame is slidably connected to the guide rail 2 located on the other side of the lifting frame. The drive motor 2 is rotatably connected to the transmission shaft 2. The gears located at both ends of the transmission shaft 2 mesh with the rack located on one side of the lifting frame, driving the lifting frame to move up and down through the moving frame. The bottom end of the lifting frame is fixedly connected to the bottle transfer device.

[0008] The above configuration involves connecting a drive motor to a transmission shaft, with transmission wheels at both ends of the shaft connected to transmission wheels on the inner side of the mobile platform frame via a transmission belt. Since the connecting block is clamped and fixed to the transmission belt, and the bottom of the mobile frame is also fixedly connected, the transmission belt drives the connecting block to move synchronously, thus achieving the effect of horizontal movement of the mobile frame and lifting device. By setting a gear and rack meshing connection on one side of the lifting frame, and a slider connected to a guide rail on the other side, the lifting frame can be raised and lowered when the drive motor rotates the transmission shaft. This design is simple and highly reliable.

[0009] Furthermore, slide rails are provided on both sides of the bottom of the fixed bracket, and sliders are fixedly connected to the extension sections at both ends of the bracket. Slider four is slidably connected to slide rails, and the extension sections are detachably connected to the fixed bracket and locked by fasteners.

[0010] The above setup, with slide rails on both sides of the bottom of the fixed bracket, allows slider four to slide and connect with slide rail one. When it is necessary to adjust the distance between bottle channel plate two and bottle channel plate one, the fixing piece will be loosened, and then the distance will be adjusted by sliding slider four and slide rail one. After that, the fixing piece on the extension section of the connecting bracket will lock the fixed bracket, thus facilitating the adjustment of the distance between bottle channel plate one and bottle channel plate two.

[0011] Furthermore, the pushing section includes an empty bottle sorting conveyor platform, a pushing device, a layer partition storage compartment, a bottle stacking mechanism, and a bottom tray storage compartment. The pushing device includes a frame, a driving device, a swinging device, and two or more fixed frames. Slider blocks are provided on both sides of the bottle holding cavity at the bottom of the frame. The slider blocks can be slidably connected to the slide rail on the conveying platform. A first baffle is fixedly provided at the bottom of one side of the frame. The swinging device is provided on the other side of the frame opposite to the first baffle. The swinging device includes a straight plate, a connecting rod, a rotating shaft, a first connecting member, and a second connecting member. The driving device is provided at the top of the frame and is rotatably connected to the first connecting member. The second connecting member is fixedly sleeved on the rotating shaft and fixedly connected to the first connecting member. The two ends of the rotating shaft are rotatably connected to the frame through hinge seats. The connecting rods located on both sides of the second connecting member are fixedly sleeved on the rotating shaft and fixedly connected to the straight plate. The fixed frames fixedly provided on the frame are fixedly provided with the second baffle. The driving device drives the straight plate to rotate and forms a bottle holding cavity at the bottom of the frame with the first baffle and the second baffle.

[0012] The above setup, by installing a drive device at the top of the frame and rotatably connecting the drive device to the first connecting member of the swing device, allows the first connecting member to rotate via a second connecting member after the drive device is activated. This causes the rotating shaft to rotate, and the connecting rod rotates synchronously with the shaft, thereby causing the straight plate to rotate towards the bottom of the frame. This forms a bottle-holding cavity at the bottom of the frame with the first and second baffles. Before the straight plate rotates, it is flush with the top plane of the frame. After the empty bottle is moved into the bottle-holding cavity at the bottom of the frame, the straight plate rotates towards the bottom of the frame, holding the empty bottle from the side. This effectively avoids contamination that would occur if the entire frame were to fall from top to bottom and then hold the empty bottle.

[0013] Furthermore, the driving device includes a cylinder, one end of which is fixedly connected to the top of the frame via a support, and the other end of which is rotatably connected to one end of the first connecting member. The first connecting member and the second connecting member are arranged perpendicularly, and the other end of the first connecting member is fixedly connected to one end of the second connecting member. The other end of the second connecting member is fixedly sleeved on the middle of the rotating shaft. Two connecting rods are provided and symmetrically arranged on both sides of the second connecting member. One end of the connecting rod is fixedly sleeved on the rotating shaft, and the other end of the connecting rod is fixedly connected to the straight plate.

[0014] The above configuration facilitates the rotation of the first connecting member by driving it with a cylinder. When the cylinder drives the first connecting member to rotate, the second connecting member's shaft can rotate synchronously. After the shaft rotates, it can simultaneously drive the connecting rod to rotate synchronously, thereby driving the straight plate to rotate.

[0015] Furthermore, the diversion device includes a platform, a first support, a second support, and a diversion rack. The platform has an opening in the middle of one end near the bottle inlet channel, and the other end of the platform is connected to the diversion channel. The opening is fixedly connected to the bottle inlet channel. The first support is fixedly installed at one end of the platform near the opening, and the second support is fixedly installed at the other end of the platform. The first and second supports are arranged in parallel. The first support has a bearing seat, one end of the rotating shaft is fixed to one end of the diversion rack, and the other end of the rotating shaft is rotatably connected to the bearing seat. The second support has a guide rail, and a slider is installed on the guide rail. The bottom of the slider is slidably connected to the guide rail, and the top of the slider is fixedly connected to a connecting plate. One end of the connecting plate is fixed with a fixing block. A transmission belt is clamped between the connecting plate and the fixing block. The transmission belt is connected to two rotating wheels, which are located above the second support. One rotating wheel is fixedly connected to the output end of a drive motor. The other end of the connecting plate is a bearing, which is rotatably connected to one end of the rotating shaft. The other end of the rotating shaft is fixedly connected to the top of the slider, and the bottom of the slider is slidably connected to the guide rail located at the other end of the diversion rack.

[0016] The above setup facilitates the entry of empty bottles into the distribution rack via the bottle inlet channel. The drive motor then rotates the transmission belt, which in turn moves one end of the connecting plate connected to the transmission belt horizontally. The other end of the connecting plate rotates around the bearing, causing the distribution rack to move synchronously. This allows the empty bottles in the distribution rack to be diverted into different distribution channels for continued transport.

[0017] Furthermore, a flow-blocking device is provided on one side of the flow-blocking frame near the bottom of the flow-blocking channel; the flow-blocking device includes a mounting frame, a cylinder and a flow-blocking block, the cylinder is fixed on the mounting frame, the output end of the cylinder is fixedly connected to one end of the flow-blocking block, and the other end of the flow-blocking block extends outward to form a protrusion. The shut-off device includes a mounting plate, a mounting bracket, a cylinder, and a shut-off block. One end of the mounting plate is fixed to the side of one end of the diversion channel by bolts. One end of the mounting bracket is fixed to the mounting plate by bolts. The other end of the mounting bracket is fixedly connected to the cylinder. The output end of the cylinder is threadedly connected to a connecting rod. One end of the connecting rod is configured as a circular protrusion. One end of the shut-off block extends outward. The other end of the shut-off block is hinged to the other end of the mounting plate. A protrusion is provided on the outer side of the other end of the shut-off block. The protrusion and the circular protrusion are hinged together.

[0018] With the above setup, when the diversion channel is full of empty bottles, the intercepting device can block the empty bottles in the diversion rack, preventing them from continuing to be transported into the diversion channel. After being fixed to one side of the diversion channel by the mounting bracket, the intercepting block can be moved by the drive cylinder to intercept the empty bottles. Then, the drive cylinder drives the stop block to rotate and open the diversion channel, allowing the empty bottles located between the stop device and the intercepting device to be transported out of the diversion channel. Next, the stop block is rotated by the drive cylinder to close the diversion channel, and the drive cylinder drives the intercepting block to move again, allowing the empty bottles in the diversion channel to continue to be transported to the position between the stop device and the intercepting device. This cycle is repeated, so that the empty bottles can be transported to the moving section in an orderly manner.

[0019] Furthermore, a bottle transfer channel is formed between the second bottle channel plate and the first bottle channel plate; a gap is provided between the first bottle channel plates; the pressing device includes a second mounting frame, a second cylinder, and a pressing block; the two ends of the second mounting frame are fixedly fixed on the first bottle channel plate, the second cylinder is fixed on the second mounting frame, and the pressing block is set in the gap between the first bottle channel plates and is fixedly connected to the output end of the second cylinder.

[0020] With the above setup, after the empty bottle enters the bottle transfer pipeline, the cylinder two can drive the pressure block to press the last empty bottle in the transfer pipeline, thereby preventing the empty bottle from tipping over during the transfer process.

[0021] Another aspect of the present invention provides a method for operating a stable and efficient automatic bottle counter, comprising the following steps: S1 Empty bottles enter the bottle inlet channel and are conveyed to the diversion device by the conveyor belt; S2 Empty bottles entering the diversion device are diverted into different diversion channels; S3 intercepts empty bottles in the diversion channel by opening the intercepting device. After the shut-off device is closed, the intercepting device is closed so that some empty bottles in the diversion channel are transported between the intercepting device and the shut-off device. After the number of empty bottles between the intercepting device and the shut-off device reaches the expected number, the intercepting device is opened again to intercept empty bottles in the diversion channel. Then the shut-off device is opened so that the empty bottles located between the intercepting device and the shut-off device are transported into the bottle transfer device. S4 Empty bottles located between the intercepting device and the shut-off device in different diversion channels enter the bottle transfer device. The first empty bottle entering the bottle transfer device is blocked by the baffle. Then the clamping device is opened to clamp the last empty bottle entering the bottle transfer device. The horizontal moving device drives the bottle transfer device to slide horizontally on the moving frame to the preset target position. The clamping device is closed. Then the lifting moving device drives the bottle transfer device to rise, so that the empty bottle is removed from the bottle transfer device. S5 The horizontal moving device moves the bottle transfer device to its original position. Then the lifting moving device moves the bottle transfer device down, so that the bottle transfer device moves to its original position. Repeat steps S3 to S5.

[0022] The above setup includes a bottle inlet channel, a diversion device, and two or more diversion channels in the conveying section. This allows empty bottles to enter the diversion device through the inlet channel and be diverted to different diversion channels for efficient conveying. A shut-off device and a flow-intercepting device are installed at the end of each diversion channel furthest from the diversion device. When the shut-off device is opened, empty bottles located between the shut-off and flow-intercepting devices in the diversion channel are conveyed into the bottle transfer device in the moving section. Simultaneously, the flow-intercepting device intercepts other empty bottles in the diversion channel, achieving a flow-intercepting effect and better controlling the number of empty bottles entering the bottle transfer device, thus increasing conveying efficiency. The bottle transfer device is driven by a lifting and moving mechanism. The system features a lifting mechanism; the second bottle guide plate slides along a fixed support in a direction away from or close to the first bottle guide plate. The distance between the first and second bottle guide plates is adjusted according to the size of the empty bottle. A fixed stop is installed at one end of the connecting support, and a pressing device is installed at the other end. After an empty bottle enters between the first and second bottle guide plates, the fixed stop prevents the first empty bottle entering from the diversion channel from reaching a preset fixed position and then stops it. The pressing device then presses down on the last empty bottle entering from the diversion channel from the side. This ensures a smoother transfer of empty bottles and prevents them from tilting or tipping over, which could lead to contamination of the bottles and affect the efficiency of the transfer operation.

[0023] Furthermore, in step S2, the flow-stopping device of the diverter is closed, and then the empty bottle in the bottle inlet channel enters the diverter through the opening. Then, the drive motor drives the rotating wheel and the transmission belt to rotate, and then the transmission belt drives the slider to slide horizontally on the guide rail on the second support. At the same time, the diverter rotates around the rotating connection between the first support and the diverter, so that the diverter is aligned with the inlet end of the diverter channel. The flow-stopping device of the diverter is opened, and the empty bottle in the diverter is diverted to different diverter channels for transportation. In step S3, when the flow-stopping device is opened, the cylinder drives the flow-stopping block to move into the diversion channel, pressing the empty bottle from the side. At the same time, the protruding part of the flow-stopping block extends outward to block the empty bottle in the direction of conveying. When the flow-stopping device is closed, the cylinder drives the flow-stopping block to move in the opposite direction and remove it from the diversion channel. When the shut-off device is opened, cylinder one drives the shut-off block to rotate 90° from the side of the diversion channel and then blocks the outlet end of the diversion channel; when the shut-off device is closed, cylinder one drives the shut-off block to rotate 90° in the opposite direction and open the outlet end of the diversion channel.

[0024] The above setup uses cylinders and other structures to drive the flow-diverting and shut-off devices to achieve the flow-diversion function. Attached Figure Description

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1 to 12 As shown, a stable and efficient automatic bottle-stacking device is used to transfer, stack, and stack empty bottles. The bottle-stacking device includes a conveying section, a moving section, and a pushing section. The conveying section includes a bottle inlet channel 1, a diversion device, and two or more diversion channels 2. In this embodiment, four diversion channels 2 are provided. The front end of the diversion device is connected to the bottle inlet channel 1, and the rear end of the diversion device is connected to the inlet end of the diversion channel 2. The outlet end of the diversion channel 2 away from the diversion device is provided with a shut-off device and a flow-blocking device.

[0039] like Figure 7As shown, the diversion device includes a platform 30, a first support 31, a second support 32, and a diversion rack 33. The platform 30 has an opening at the center of one end near the bottle inlet channel 1, and the other end of the platform 30 is connected to the diversion channel 2. The opening is fixedly connected to the bottle inlet channel 1. The first support 31 is fixedly installed at the end of the platform 30 near the opening, and the second support 32 is fixedly installed at the other end of the platform 30. The first support 31 and the second support 32 are arranged parallel to each other. The first support 31 has a bearing seat 311, one end of a rotating shaft is fixed to one end of the diversion rack 33, and the other end of the rotating shaft is rotatably connected to the bearing seat 311. The second support 32 has a guide rail 321, and a slider 322 is mounted on the guide rail 321. The bottom of the slider 322 is slidably connected to the guide rail 321, and the top of the slider 322 is fixedly connected to a connecting plate 323. A fixing block 324 is fixed to one end of the connecting plate 323. A transmission belt is clamped between the connecting plate 323 and the fixing block 324. The transmission belt is connected to two rotating wheels, which are located above the second bracket 32. One rotating wheel is fixedly connected to the output end of the drive motor 325. A bearing is provided on the other end of the connecting plate 323. The bearing is rotatably connected to one end of the rotating shaft. The other end of the rotating shaft is fixedly connected to the top of the slider 326. The bottom of the slider 326 is slidably connected to the guide rail 327 located at the other end of the diversion rack 33. This allows the transmission belt to rotate after the empty bottle in the bottle inlet channel 1 enters the diversion rack 33, thereby driving the connecting plate 323 to move horizontally. This enables the diversion rack 33 to move synchronously, thus diverting the empty bottles in the diversion rack 33 to different diversion channels 2 for continued transport.

[0040] like Figure 7 and Figure 9 As shown, a flow-blocking device is provided on one side of the flow-blocking frame 33 near the bottom of the flow-blocking channel 2. The flow-blocking device includes a mounting frame 11, a cylinder 12, and a flow-blocking block 13. The cylinder 12 is fixed on the mounting frame 11, and the output end of the cylinder 12 is fixedly connected to one end of the flow-blocking block 13. The other end of the flow-blocking block 13 extends outward to form a protrusion. In this embodiment, the mounting frame 11 is provided with a through hole. The mounting frame 11 is fixed to the bottom side of the flow-blocking frame 33 by bolts passing through the through hole. By fixing the flow-blocking block 13 to one side of the flow-blocking channel 2 by bolts passing through the through hole on the mounting frame 11, the flow-blocking block 13 can be moved into the flow-blocking channel by driving the cylinder 12 to intercept the empty bottle in the flow-blocking channel 2.

[0041] like Figure 6 and Figure 8As shown, the shut-off device includes a mounting plate 21, a mounting bracket 22, a cylinder 23, and a shut-off block 24. One end of the mounting plate 21 is fixed to the side of one end of the diversion channel 2 by bolts. One end of the mounting bracket 22 is fixed to the mounting plate 21 by bolts. The other end of the mounting bracket 22 is fixedly connected to the cylinder 23. The output end of the cylinder 23 is threadedly connected to a connecting rod 25. One end of the connecting rod 25 is configured as a circular annular protrusion 26. One end of the shut-off block 24 extends outward. The other end of the shut-off block 24 is hinged to the other end of the mounting plate 21. A protrusion 27 is provided on the outer side of the other end of the shut-off block 24. The protrusion 27 and the circular annular protrusion 24 are connected. The components 26 are hinged together. A through hole is provided on the protrusion 27. The rotating shaft (not shown in the figure) passes through the through hole, so that the protrusion 27 and the annular protrusion 26 are hinged together. In this embodiment, the cylinder 23 drives the stop block 24 to rotate and open the outlet end of the diversion channel 2, so that the empty bottle located between the stop device and the intercepting device is transported out of the diversion channel 2. Then, the cylinder 23 drives the stop block 24 to rotate and close the diversion channel 2. The cylinder 12 drives the intercepting block 13 to move again, so that the empty bottle in the diversion channel 2 continues to be transported to the position between the stop device and the intercepting device. This cycle is repeated so that the empty bottle can be transported to the moving section in an orderly manner.

[0042] like Figure 2-4 As shown, the moving section includes a moving platform frame 04, a moving device, and a bottle-transferring device. A conveying platform is fixedly installed at the bottom of the moving platform frame 04. The moving device includes a horizontal moving device and a lifting moving device. The horizontal moving device includes a guide rail 41, a moving frame 42, a drive motor 43, and a transmission shaft 44. The guide rail 41 is fixed on the moving platform frame 04. The moving frame 42 is slidably connected to the guide rail 41 via a slider 45. The drive motor 43 is rotatably connected to the transmission shaft 44. The drive wheels 46 at both ends of the transmission shaft 44 are connected to the drive wheels 47 located inside the moving platform frame 04 via a transmission belt. The bottom end of the moving frame 42 is fixedly connected to one end of a connecting block 48. The other end of the connecting block 48 is configured as two clamping plates, which are fixedly clamped to the transmission belt by bolts.

[0043] The lifting and moving device includes a second drive motor 51, a second transmission shaft 52, and two or more lifting frames 53. In this embodiment, there are two lifting frames 53. A third slider 49 fixed on the moving frame 42 is slidably connected to a second guide rail 54 on the other side of the lifting frame 53. The second drive motor 51 is rotatably connected to the second transmission shaft 52. In this embodiment, the moving frame 42 is provided with two first bearing seats 40. The second transmission shaft 52 is provided on the moving frame 42 and is rotatably connected to the first bearing seats 40. The gears 55 at both ends of the second transmission shaft 52 are correspondingly meshed with the rack 56 on one side of the lifting frame 53 and drive the lifting frame 53 to move up and down through the moving frame 42. The bottom end of the lifting frame 53 is fixedly connected to the bottle transfer device.

[0044] like Figure 5 As shown, the bottle transfer device includes a fixed bracket 6 and two or more connecting brackets 7. The bottom end of the lifting frame 53 is fixedly connected to the fixed bracket 6. In this embodiment, four connecting brackets 7 are provided. Two bottle channel plates 71 are fixed on one side of the connecting bracket 7, and there is a gap between the bottle channel plates 71. Two parallel bottle channel plates 62 are fixed at the bottom of the fixed bracket 6. The connecting brackets 7 are arranged on both sides of the bottle channel plates 62. The bottle channel plates 62 are parallel to the bottle channel plates 71. A bottle transfer channel is formed between the bottle channel plates 71 and the bottle channel plates 62 on the connecting bracket 7. Slide rails are provided on both sides of the bottom of the fixed bracket 6. 61. The slide rail 61 is perpendicular to the straight line direction of the bottle channel plate 62. The extension sections 77 at both ends of the connecting bracket 7 are fixedly connected to the slider 74. The slider 74 is slidably connected to the slide rail 61. The extension section 77 is fixedly connected to the fixed bracket 6 by the fixing member 78. In this embodiment, one end of the fixing member 78 is fixedly connected to the extension section 77, and the other end of the fixing member 78 is provided with a through hole. The other end of the fixing member 78 is locked to the fixed bracket 6 by bolts passing through the through hole. In this way, the extension section 77 can fix the entire connecting bracket 7 to the fixed bracket 6. One end of the connecting bracket 7 is provided with a fixing block 76, such as... Figure 12 As shown, one end of the fixed stop 76 extends into the channel of the bottle transfer device, and the other end of the connecting bracket 7 is provided with a pressing device. The pressing device includes a second mounting bracket 87, a second cylinder 88, and a pressing block 89. The two ends of the second mounting bracket 87 are respectively fixed on the first bottle channel plate 71, the second cylinder 88 is fixed on the second mounting bracket 87, and the pressing block 89 is set at the gap between the first bottle channel plates 71 and is fixedly connected to the output end of the second cylinder 88. The outlet end of the diversion channel 2 is aligned with the first bottle channel plate 71 and the second bottle channel plate 62 to form a bottle transfer pipe. In this way, after the empty bottle of the diversion channel 2 enters the bottle transfer pipe, the second cylinder 88 can drive the pressing block 89 to press the last empty bottle in the bottle transfer pipe, thereby preventing the empty bottle from tipping over during the transfer of the empty bottle.

[0045] like Figure 1As shown, the pushing section includes an empty bottle sorting conveyor platform z2, a pushing device, a shelf storage bin z3, a bottle stacking mechanism z4, and a bottom tray storage bin z5. One end of the empty bottle sorting conveyor platform z2 is connected to the conveyor platform at the bottom of the mobile platform frame 04, and the other end of the empty bottle sorting conveyor platform z2 is connected to the conveyor platform located at the bottom of the pushing device. This allows the empty bottles from the bottle transfer device to be transferred to the empty bottle sorting conveyor platform z2 via the conveyor platform, and then pushed to a preset position via the conveyor platform at the bottom of the pushing device. The empty bottle sorting conveyor platform z2 is used to place empty bottles transferred by the bottle transfer device; the partition storage compartment z3 is used to store the partitions; the bottle stacking mechanism z4 is used to push the empty bottles on the empty bottle sorting conveyor platform z2 to a preset position for stacking; and the bottom tray storage compartment z5 is used to store the trays. The empty bottle sorting conveyor platform z2, the partition storage compartment z3, the bottle stacking mechanism z4, and the bottom tray storage compartment z5 have been specifically described in Chinese patent document application number 202120759967.3, and will not be repeated here.

[0046] like Figure 10As shown, the pushing device is located between the empty bottle sorting conveyor platform z2 and the bottle counter mechanism z4, and includes a frame a1, a driving device, a swinging device, and two or more fixed frames a2. A first baffle a11 is fixedly installed at the bottom of one side of the frame a1. The swinging device is located on the other side of the frame a1 opposite to the first baffle a11. The swinging device includes a straight plate a21, a connecting rod a22, a rotating shaft a23, a first connecting piece a24, and a second connecting piece a25. The driving device is located at the top of the frame a1 and includes a cylinder a3. One end of the cylinder a3 is supported by a bracket a3. 1. Fixedly connected to the frame a1, in this embodiment, the other end of the cylinder a3 is threadedly fixedly connected to a connecting rod a32. One end of the connecting rod a32 is configured as an annular protrusion a33. One end of the first connecting member a24 is provided with a slot a34 that matches the annular protrusion a33. The fixed shaft passes through the annular protrusion a33 and is fixed in the slot a34, thus enabling a rotatable connection between the cylinder a3 and the first connecting member a24. The first connecting member a24 and the second connecting member a25 are arranged perpendicularly, and the other end of the first connecting member a24 is fixedly connected to one end of the second connecting member a25. The other end of the second connecting piece a25 is fixedly sleeved on the middle of the rotating shaft a23. Thus, when the cylinder a3 extends or retracts to drive the first connecting piece a24 to swing, the upper end of the second connecting piece a25 is simultaneously fixedly connected to the first connecting piece a24. This allows the second connecting piece a25 to swing while remaining fixedly connected to the rotating shaft a23, enabling the rotating shaft a23 to rotate synchronously via the second connecting piece a25. In this embodiment, a hinge seat (not shown in the figure) is fixedly provided on the frame a1. Both ends of the rotating shaft a23 are rotatably connected to the frame a1 via the hinge seat. The connecting rod a... Two connecting rods a22 are provided and symmetrically arranged on both sides of the second connecting member a25. One end of the connecting rod a22 is fixedly sleeved on the rotating shaft a23, and the other end of the connecting rod a22 is fixedly connected to the straight plate a21. In this embodiment, the connecting rod a22 is an L-shaped rod. The fixing frame a2 is symmetrically arranged on both sides of the frame a1. One end of the fixing frame a2 is fixed to the top of the frame a1, and the other end of the fixing frame a2 extends along the height direction of the frame a1 to the bottom of the frame a1 and is fixedly provided with a second baffle a12. The length of the first baffle a11 matches the distance between the second baffle a12.

[0047] like Figure 1As shown, the second baffle a12 extends outward from the end away from the first baffle a11. This facilitates the formation of a bottle-holding cavity a13 at the bottom of the frame a1 after the straight plate a21 rotates, together with the first baffle a11 and the second baffle a12. It also guides the empty bottle as it moves into the bottle-holding cavity a13. In the figure, before the cylinder a3 drives the straight plate a21 to rotate, the straight plate a21 is flush with the top plane of the frame a1. After the empty bottle moves into the bottle-holding cavity a14 at the bottom of the frame a1, the cylinder a3 drives the straight plate a21 to rotate towards the bottom of the frame a1, so that the straight plate a21 can hold the empty bottle from the side. This effectively avoids contamination that would occur if the entire frame a1 fell from top to bottom and then held the empty bottle.

[0048] At the bottom of the frame a1, on both sides of the bottle-holding cavity a13, there are sliders that can slide and connect with the slide rails on the conveying platform, thereby realizing the horizontal movement of the frame a1. One end of the frame a1 is fixedly connected to the partition plate suction mechanism 4. This makes it easy to simultaneously move the partition plate above the bottle-stacking mechanism by adsorbing the partition plate after the empty bottle is gripped and moved, so that the partition plate is placed above the empty bottle to achieve the function of separating layers. The partition plate suction mechanism 4 has been described in detail in the document with patent application number 202120759967.3, and will not be repeated here.

[0049] like Figure 1-12 As shown, a stable and efficient automatic bottle counter operates by means of the following specific steps: S1 Empty bottles enter the bottle inlet channel and are conveyed to the diversion device by the conveyor belt; S2 Before the empty bottle enters the diversion device, the flow-stopping device of the diversion rack is opened. After the empty bottle enters the diversion rack through the opening in the bottle inlet channel, the drive motor is controlled to drive the rotating wheel and the transmission belt to rotate. Then, the transmission belt drives the slider to slide horizontally on the guide rail on the second support. At the same time, it drives the end of the diversion rack near the transmission belt to rotate around the rotating connection between the first support and the diversion rack, so that the diversion rack is aligned with the inlet end of the diversion channel. The flow-stopping device of the diversion rack is closed, and the empty bottle in the diversion rack is diverted to different diversion channels for transportation. S3 intercepts empty bottles in the diversion channel by opening the intercepting device. After the shut-off device is closed, the intercepting device is closed so that some empty bottles in the diversion channel are transported between the intercepting device and the shut-off device. After the number of empty bottles between the intercepting device and the shut-off device reaches the expected number, the intercepting device is opened again to intercept empty bottles in the diversion channel. Then the shut-off device is opened so that the empty bottles located between the intercepting device and the shut-off device are transported into the bottle transfer device. S4 Empty bottles located between the intercepting device and the shut-off device in different diversion channels enter the bottle transfer device. Then, the clamping device is opened to clamp the last empty bottle entering the bottle transfer device. Drive motor one drives the transmission shaft to rotate, and then drives the moving frame to slide horizontally on the moving frame to the preset target position through the transmission belt. The clamping device is closed. Then, drive motor two drives the transmission shaft two to rotate. Through the meshing of gears and racks, the lifting frame and the bottle transfer device are raised, so that the empty bottle is removed from the bottle transfer device. S5 Drive motor one drives the transmission shaft to rotate in the reverse direction, and then drives the moving frame, lifting and moving device and bottle transfer device to move to the original position through the transmission belt. Then drive motor two drives the transmission shaft two to rotate in the reverse direction, and drives the lifting frame and bottle transfer device to descend through the meshing of gear and rack, so that the bottle transfer device moves to the original position. Repeat steps S3 to S5.

[0050] In this embodiment, when the flow-blocking device is opened, the cylinder drives the flow-blocking block to move into the diversion channel, pressing the empty bottle from the side. At the same time, the protruding part of the flow-blocking block extends outward to block the empty bottle in the direction of conveying. When the flow-blocking device is closed, the cylinder drives the flow-blocking block to move in the opposite direction and remove it from the diversion channel. When the shut-off device is closed, cylinder one drives the shut-off block to rotate 90° from the side of the diversion channel and then blocks the outlet end of the diversion channel; when the shut-off device is opened, cylinder one drives the shut-off block to rotate 90° in the opposite direction to open the outlet end of the diversion channel, so that the empty bottle located between the shut-off device and the intercepting device is transported from the outlet end of the diversion channel to the bottle transfer pipe of the bottle transfer device.

[0051] The working principle of this invention is as follows: A bottle inlet channel 1, a diversion device, and two or more diversion channels 2 are provided in the conveying section. This allows empty bottles to enter the diversion device through the bottle inlet channel 1 and be diverted to different diversion channels 2 for efficient conveying. A stop device and a flow-blocking device are provided at the end of the diversion channel 2 furthest from the diversion device. When the stop device is opened, empty bottles located between the stop device and the flow-blocking device in the diversion channel 2 are conveyed into the bottle transfer device in the moving section. Simultaneously, the flow-blocking device intercepts other empty bottles in the diversion channel, achieving a flow-blocking effect and better controlling the number of empty bottles entering the bottle transfer device, resulting in higher conveying efficiency. The bottle transfer device is raised and lowered by a lifting and moving device. Bottle guide plate 2 62 is slidably mounted on the fixed bracket 6 in a direction away from or close to bottle guide plate 1 71. The distance between bottle guide plate 1 71 and bottle guide plate 2 62 is adjusted according to the size of the empty bottle. A fixed stop 76 is provided at one end of the connecting bracket 7, and a pressing device is provided at the other end of the connecting bracket 7. After the empty bottle enters between bottle guide plate 1 71 and bottle guide plate 2 62, the fixed stop 76 can prevent the first empty bottle entering from the diversion channel 2 from reaching the preset fixed position and stopping. The pressing device can then press the last empty bottle entering from the diversion channel 2 from the side. In this way, the transfer of empty bottles can be more stable and prevent the empty bottles from tilting or tipping over, which would cause contamination of the empty bottles and affect the efficiency of the transfer operation.
