The mechanism also includes a support plate unit for supporting and unloading the glass bottles. The present invention drives the supporting plate to move back and forth relative to the lower bracket through a reciprocating component.

Description

Technical Field

[0001] The invention relates to the technical field of glass bottle storage, in particular to a glass bottle positioning and stacking mechanism. Background Art

[0002] Glass bottles are widely used as packaging containers in the food, beverage, and pharmaceutical industries. They require efficient and stable palletizing operations during production, storage, and transportation. Neat palletizing not only improves storage space utilization, but also reduces collisions and damage during transportation, thereby ensuring product quality.

[0003] At present, the common glass bottle palletizing equipment usually includes a baffle plate structure and a support plate structure that move along the track. The equipment drives the baffle plate to move to the periphery of the glass bottle matrix through the track frame. The glass bottle matrix is ​​as follows: Figure 8 As shown, the bottle group is framed and fixed as a whole, and then the enclosure plate and the supporting plate below move in coordination to transport the glass bottle group to the target stacking area. After arriving at the designated position, the enclosure plate remains stationary and the supporting plate returns to its initial position. The glass bottles fall layer by layer to the stacking area due to the loss of support.

[0004] However, the existing equipment still has two shortcomings: First, during the falling stage of the glass bottles, in order to avoid the bottle body being stuck due to the continuous clamping of the baffle, the baffle needs to release the constraint on the bottle body in advance, resulting in a lack of lateral limit for the glass bottles during the falling process, which is prone to tilting and affects the neatness and stability of the stacking.

[0005] Secondly, when the glass bottle has completely fallen, the baffle needs to correct the position of the tilted bottle body. However, since the bottle body has moved down a certain distance, the baffle can only act on the upper part of the bottle body, making it difficult to apply uniform thrust, resulting in limited correction effect. When the lower part of the bottle body is not effectively constrained, it may only tilt but not move, further reducing the stacking accuracy. Summary of the Invention

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a glass bottle positioning and stacking mechanism, including a track frame that moves left and right along the track, four panels controlled by electric cylinders are hinged at the lower part of the track frame, and a bottle pushing unit for correcting the position of the glass bottles is commonly provided on the four panels. The mechanism also includes a support plate unit for supporting and unloading the glass bottles.

[0007] The bottle pushing unit includes a pushing plate arranged on the enclosure through a flip assembly and used to push the lower part of the glass bottle body after it falls. Bottle clamping blocks that contact the bottle body are arranged at equal intervals in the left and right directions on the pushing plates on the front and rear sides. When the bottle clamping blocks contact the bottle body, the bottle body is pushed back and forth left and right through the guide assembly.

[0008] The support plate unit includes a lower bracket that slides left and right on the track, a bearing plate is provided on the upper side of the lower bracket for sliding left and right, and a reciprocating component is provided on the rear side of the lower bracket and the bearing plate for driving the bearing plate to swing left and right relative to the lower bracket.

[0009] Preferably, the flip assembly includes a linkage rod rotatably arranged on the enclosure, the linkage rod is fixedly connected to the push plate through a connecting support plate, a swing plate is fixedly installed in the middle of the linkage rod, and the end of the swing plate is hinged to the enclosure through a hydraulic push rod.

[0010] Preferably, the guide assembly includes a sliding frame arranged on the front and rear push plates at equal intervals along the left and right directions. The sliding frame is connected to the push plates for left and right sliding. The bottle holding block is connected to the inner side of the sliding frame for front and back sliding. A coil spring is arranged between the bottle holding block and the sliding frame.

[0011] Preferably, fixed rods are fixedly installed at equal intervals on the left and right sides of the pushing plates on the front and rear sides, the fixed rods correspond to the sliding frames one by one, and a continuously bent guide groove is opened on the bottle clamping block, and the fixed rods slide inside the guide groove.

[0012] Preferably, two groups of bottle pushing blocks are provided on the push plates on the left and right sides for sliding left and right, and the two groups of bottle pushing blocks are staggered front and back. The bottle pushing blocks in the same group are fixedly installed with a synchronization plate on one side away from the enclosure plate, and the bottle pushing blocks are locked together with the push plates by fastening screws.

[0013] Preferably, the lower bracket and the left part of the supporting plate are sloped with the same slope, the right part of the lower bracket is an inclined structure, the lower part of the right part of the supporting plate is a vertical surface, and the upper part is an inclined surface with the same slope as the right part of the lower bracket.

[0014] Preferably, the reciprocating assembly includes a driving motor fixedly mounted on the rear side of the lower bracket, a crank disk fixedly mounted on the output shaft of the driving motor, and a spring telescopic plate is hinged between the eccentric position of the crank disk and the bearing plate.

[0015] Preferably, two rotating rollers arranged symmetrically on the left and right are rotatably provided on the inner side of the supporting plate, a conveyor belt is wound between the two rotating rollers, the front end of the right rotating roller is connected to a gear through a ratchet structure, and a rack is provided at the front end of the right side of the track for sliding up and down.

[0016] Preferably, a U-shaped plate is provided on the front side of the supporting plate and on the outside of the corresponding gear for sliding up and down, and teeth for locking the rotation of the gear are provided on the upper side of the horizontal section of the U-shaped plate, and a compression spring is provided between the U-shaped plate and the supporting plate.

[0017] Preferably, an electric push rod for driving the rack to move up and down is fixedly installed on the front side of the track, and a lower pressure plate is fixedly installed on the rear side of the rack.

[0018] The beneficial effects of the present invention are as follows: 1. The present invention drives the carrying plate to move back and forth relative to the lower bracket through a reciprocating assembly. During this process, the regular shaking of the carrying plate exerts a lateral thrust on the glass bottles falling onto the lower bracket, forcing the bottle bodies to gradually align and arrange them closely, effectively preventing tilting. At the same time, the conveyor belt on the carrying plate engages with the rack on the track. When the carrying plate moves to the left, the gear drives the conveyor belt to transport the glass bottles to the right, further ensuring that the bottles are closely arranged.

[0019] 2. The present invention adopts a flip assembly to drive the push plate to flip downward, so that the bottle-holding block on the push plate acts accurately on the lower part of the glass bottle body. Combined with the limitation of the baffle on the upper part of the bottle body, a bidirectional clamping force is formed up and down, and the position of the bottle body is corrected synchronously. It breaks through the limitation of the existing technology that the baffle can only push the upper part of the bottle body, effectively eliminates the tilting and non-movement phenomenon caused by the unconstrained lower part of the bottle body, and improves the stacking accuracy.

[0020] 3. The present invention adopts a guide assembly to guide the bottle clamping block, so that the fixed rod cooperates with the continuously bent guide groove on the bottle clamping block to drive the bottle clamping block to move back and forth along a preset path. During this process, the bottle clamping block continuously applies a reciprocating lateral thrust to the bottle body, thereby moving the glass bottle when correcting it, preventing the bottle body from getting stuck and not falling completely.

[0021] Fourth, the present invention adopts two sets of individually adjustable bottle pushing blocks to clamp and push the left and right sides of the glass bottle array, so as to adapt to the precise correction of the staggered glass bottle matrix, improve the positioning accuracy of each layer of the glass bottle matrix, further ensure the stability of palletizing, and by manually adjusting the position of the bottle pushing blocks, it can adapt to glass bottles of different diameters.

[0032] The following embodiments of the present invention are described in detail. The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, the techniques or conditions described in the literature in the art or in the product specifications shall be followed.

[0033] See Figure 1 、 Figure 2 and Figure 5 A glass bottle positioning and stacking mechanism includes a track frame 1 that moves left and right along a track 5. Four panels 2 controlled by electric cylinders are hinged at the lower part of the track frame 1. A bottle pushing unit 3 for correcting the position of the glass bottles is commonly provided on the four panels 2. The mechanism also includes a support plate unit 4 for supporting and unloading the glass bottles.

[0034] In the initial state, the four enclosure panels 2 are located on the left side of the track 5 , and the four enclosure panels 2 are located on the left side of the pallet unit 4 .

[0035] It should be noted that the glass bottles are transported forward by the existing conveyor belt, and the four panels 2 are all arranged above the front of the conveyor belt, and the panel 2 at the rear is flipped upward under the control of the corresponding electric cylinder, so that the conveyor belt drives the glass bottles to move between the four panels 2. After the number of glass bottles between the four panels 2 reaches a certain number, the rear panel 2 is driven to flip downward by controlling the rear electric cylinder, so that the four panels 2 are framed on the outside of the glass bottle matrix, and the glass bottle matrix is ​​limited by the panel 2.

[0036] Then the track frame 1 is moved to the right along the track 5, so that the track frame 1 drives the glass bottle matrix to move to the upper part of the pallet unit 4 through the four panels 2, and then the pallet unit 4 and the four panels 2 are moved to the right to the stacking area synchronously. After that, the positions of the four panels 2 remain unchanged, and the pallet unit 4 is moved to the left to the initial position, so that the glass bottles fall layer by layer to the stacking area under the action of gravity.

[0037] During the process of the pallet unit 4 moving to the left, the pallet unit 4 can push and correct the falling glass bottles by reciprocating movement, so that the glass bottles remain in a vertical state and fall closely together. When the pallet unit 4 moves to the initial position, the bottle pushing unit 3 cooperates with the four surrounding plates 2 to push and correct the glass bottle array, so that the glass bottles are arranged closely together, ensuring the stability of the glass bottle stacking.

[0038] See Figure 1 and Figure 2 The pallet unit 4 includes a lower bracket 41 that slides left and right on the track 5, and a supporting plate 42 is provided on the upper side of the lower bracket 41 for sliding left and right. The rear sides of the lower bracket 41 and the supporting plate 42 are jointly provided with a reciprocating component 43 that drives the supporting plate 42 to swing left and right relative to the lower bracket 41.

[0039] See Figure 2 and Figure 4 The lower bracket 41 and the left part of the supporting plate 42 are sloped surfaces with the same slope, the right part of the lower bracket 41 is an inclined structure, the lower part of the right part of the supporting plate 42 is a vertical surface, and the upper part is an inclined surface with the same slope as the right part of the lower bracket 41.

[0040] In the initial state, the supporting plate 42 is located in the center of the upper part of the lower bracket 41, so that the lower bracket 41 and the sloped surface on the left side of the supporting plate 42 are arranged coplanar, and the inclined surface on the right side of the supporting plate 42 is coplanar with the inclined surface on the right side of the lower bracket 41.

[0041] When the four enclosures 2 push the glass bottle array to move to the right, the glass bottles in the rightmost row of the glass bottle array first contact the slope of the left part of the lower bracket 41, causing the glass bottles to move upward along the slope of the left part of the lower bracket 41, and then the glass bottles in the rightmost row contact the slope of the left part of the supporting plate 42, and then the glass bottles move along the slope of the left part of the supporting plate 42 to the upper part of the supporting plate 42.

[0042] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4 Two rotating rollers 421 arranged symmetrically on the left and right sides are rotatably provided on the inner side of the supporting plate 42, a conveyor belt 422 is wound between the two rotating rollers 421, the front end of the right rotating roller 421 is connected to a gear 423 through a ratchet structure, and a rack 424 is provided at the front end of the right side of the track 5 for sliding up and down.

[0043] See Figure 3 A U-shaped plate 425 is provided on the front side of the supporting plate 42 and corresponds to the outside of the gear 423 for sliding up and down. The upper side of the horizontal section of the U-shaped plate 425 is provided with teeth for locking the rotation of the gear 423, and a compression spring is provided between the U-shaped plate 425 and the supporting plate 42.

[0044] See Figure 1 and Figure 2 An electric push rod 426 for driving the rack 424 to move up and down is fixedly installed on the front side of the track 5, and a lower pressure plate 427 is fixedly installed on the rear side of the rack 424.

[0045] It should be noted that if Figure 1 As shown, the track 5 in this embodiment is divided into two parts, both of which are plate-shaped structures. The track frame 1 slides left and right on the upper part of the track 5, and the lower bracket 41 slides left and right on the lower part of the track 5. The lower bracket 41 and the track frame 1 are both powered by the existing track moving assembly.

[0046] like Figure 3 As shown, the ratchet structure in this embodiment includes a ratchet fixedly mounted on the front end of the right rotating roller 421, a gear 423 is rotatably connected to the front end of the right rotating roller 421, and pawls that cooperate with the ratchet are hinged at equal intervals inside the gear 423. A torsion spring is provided between the pawl and the gear 423, which is not shown in the figure. When the gear 423 rotates clockwise, the gear 423 drives the right rotating roller 421 to rotate synchronously through the ratchet and the pawl, and vice versa, the rotating roller 421 is not driven to rotate.

[0047] In the initial state, the compression spring pushes the U-shaped plate 425 upward by its own elastic force, so that the U-shaped plate 425 drives the teeth on its horizontal section to insert into the tooth groove at the bottom of the gear 423, thereby locking the rotation angle of the gear 423. At the same time, the gear 423 limits the ratchet wheel through the pawl, so that the right rotating roller 421 can only rotate in one direction clockwise.

[0048] When the four enclosures 2 drive the glass bottle array to move to the upper part of the supporting plate 42, the glass bottle array moves on the conveyor belt 422 and pushes the upper part of the conveyor belt 422 to move to the right, thereby causing the conveyor belt 422 to drive the rotating roller 421 to rotate clockwise, thereby improving the smoothness of the glass bottle array moving to the upper part of the supporting plate 42 and reducing the wear on the bottom of the glass bottles.

[0049] Then, the four enclosures 2 and the lower bracket 41 are driven to move synchronously to the right through the existing track moving assembly, and the lower bracket 41 drives the glass bottle array to move synchronously through the carrying plate 42 until the glass bottle array moves to the stacking area.

[0050] In the initial state, the telescopic section of the electric push rod 426 is in an extended state, so that the electric push rod 426 drives the rack 424 to be located on the upper part of the supporting plate 42. When the glass bottle array moves to the stacking area, the telescopic section of the electric push rod 426 is retracted, so that the electric push rod 426 drives the rack 424 to move downward, and the rack 424 drives the lower pressure plate 427 to move downward synchronously.

[0051] It should be noted that the lower side surface of the lower pressure plate 427 is located below the teeth of the rack 424, so that the lower pressure plate 427 first contacts the upper side surface of the vertical section of the U-shaped plate 425 and pushes it downward. When the teeth on the horizontal section of the U-shaped plate 425 are completely disengaged from the gear 423, the rack 424 moves downward to engage with the upper part of the gear 423.

[0052] See Figure 1 、 Figure 2 and Figure 4 The reciprocating assembly 43 includes a drive motor 431 fixedly mounted on the rear side of the lower bracket 41 , a crank disk 432 is fixedly mounted on the output shaft of the drive motor 431 , and a spring telescopic plate 433 is hinged between the eccentric position of the crank disk 432 and the bearing plate 42 .

[0053] When the rack 424 is engaged with the gear 423, the clamping force of the four enclosures 2 on the glass bottle array is weakened by controlling the electric cylinder to prevent the glass pieces from pressing against each other and getting stuck. Then the lower bracket 41 is moved to the left to the initial position, and the drive motor 431 is started to drive the crank disk 432 to rotate, so that the crank disk 432 moves the supporting plate 42 back and forth left and right through the spring expansion plate 433, so that the supporting plate 42 moves back and forth left and right relative to the lower bracket 41.

[0054] When the lower bracket 41 moves to the left, the positions of the four enclosures 2 remain unchanged, so that the four enclosures 2 push the position of the glass bottle array unchanged, causing the lower bracket 41 to move to the left relative to the glass bottle array. When the supporting plate 42 moves to the left relative to the lower bracket 41, the supporting plate 42 no longer supports the row of glass bottles on its right side, so that the row of glass bottles on the right side of the supporting plate 42 falls onto the lower bracket 41.

[0055] When the supporting plate 42 moves to the left relative to the lower bracket 41, the supporting plate 42 overlaps with the leftward movement of the lower bracket 41, so that the supporting plate 42 moves quickly to the left relative to the rack 424, and the supporting plate 42 drives the gear 423 to move synchronously, so that the gear 423 rotates clockwise on the rack 424, so that the gear 423 drives the conveyor belt 422 to rotate through the rotating roller 421, and the conveyor belt 422 pushes the glass bottles on it to the right quickly, so that the glass bottles are close together when unloading.

[0056] When the supporting plate 42 moves to the right relative to the lower bracket 41, the supporting plate 42 pushes the glass bottle on its right side through the vertical surface on its right side, so that the cylindrical surface of the glass bottle rests on the vertical surface on the right side of the supporting plate 42, thereby straightening the skewed glass bottle, and the spring expansion plate 433 contracts and buffers, which can prevent the supporting plate 42 from pushing the glass bottle too much and causing the glass bottle to break.

[0057] When the lower bracket 41 moves to the left and no longer blocks the glass bottles, the glass bottles fall to the palletizing area under the action of gravity, thereby unloading the glass bottles row by row until all the glass bottles fall to the palletizing area. Then the lower bracket 41 drives the supporting plate 42 to move to the left to the initial position and stops driving the motor 431.

[0058] See Figure 1 、 Figure 5 and Figure 6 The bottle pushing unit 3 includes a pushing plate 32 arranged on the enclosure 2 through a flip assembly 31 and used to push the lower part of the glass bottle after it falls. Bottle clamping blocks 33 that contact the bottle body are arranged at equal intervals in the left and right directions on the pushing plates 32 on the front and rear sides. When the bottle clamping blocks 33 contact the bottle body, the bottle body is pushed back and forth left and right through the guide assembly 34.

[0059] See Figure 1 、 Figure 5 and Figure 7 The flip assembly 31 includes a linkage rod 311 rotatably arranged on the enclosure 2. The linkage rod 311 is fixedly connected to the push plate 32 through a connecting support plate. A swing plate 312 is fixedly installed in the middle of the linkage rod 311. The end of the swing plate 312 is hinged to the enclosure 2 through a hydraulic push rod 313.

[0060] When all the glass bottles fall into the stacking area, the glass bottles move downward relative to the enclosure 2, so that the enclosure 2 corresponds to the upper position of the bottle body, and then the telescopic sections of the two hydraulic push rods 313 at the front and rear positions are extended, so that the front and rear hydraulic push rods 313 drive the corresponding linkage rods 311 to rotate by pushing the swing plate 312, and the linkage rod 311 drives the front and rear push plates 32 to flip to the lower part of the corresponding enclosure 2.

[0061] See Figure 5 and Figure 6 The guide assembly 34 includes a sliding frame 341 arranged on the front and rear sides of the push plate 32 at equal intervals along the left and right directions. The sliding frame 341 is connected to the push plate 32 for left and right sliding movement. The bottle clamping block 33 is connected to the inner side of the sliding frame 341 for front and back sliding movement. A coil spring is arranged between the bottle clamping block 33 and the sliding frame 341.

[0062] See Figure 6Fixed rods 342 are fixedly installed on the pushing plates 32 on the front and rear sides at equal intervals in the left and right directions. The fixed rods 342 correspond one-to-one to the sliding frames 341. A continuously bent guide groove is opened on the bottle clamping block 33, and the fixed rods 342 slide inside the guide groove.

[0063] In the initial state, the coil spring pushes the bottle-holding block 33 by its own elastic force, so that the bottle-holding block 33 moves toward the middle of the track frame 1, and the fixing rod 342 is located at the end of the guide groove away from the middle of the track frame 1. When the two flipping push plates 32 at the front and rear drive the bottle-holding block 33 to rest against the bottle body, the push plate 32 pushes the bottle body through the bottle-holding block 33, so that the glass bottles are arranged closely.

[0064] At the same time, the reaction force of the glass bottle on the bottle-holding block 33 pushes the glass bottle away from the middle of the track frame 1, so that the bottle-holding block 33 drives the guide groove thereon to move synchronously, so that the fixed rod 342 drives the bottle-holding block 33 and the sliding frame 341 to move back and forth left and right by pushing the guide groove, so that the bottle-holding block 33 moves the glass bottle to prevent the bottle from getting stuck and not falling completely.

[0065] See Figure 5 、 Figure 7 and Figure 8 Two groups of bottle pushing blocks 321 are slidably provided on the pushing plates 32 on the left and right sides. The two groups of bottle pushing blocks 321 are staggered front to back. The bottle pushing blocks 321 in the same group are fixedly installed with a synchronization plate 322 on the side away from the enclosure 2. The bottle pushing blocks 321 are locked together with the pushing plates 32 by fastening screws. Each group of bottle pushing blocks 321 is composed of a number of bottle pushing blocks 321 arranged at equal intervals along the front and back direction.

[0066] The operator moves the two synchronous plates 322 in advance according to the diameter of the glass bottle, so that the two synchronous plates 322 respectively drive the two groups of bottle pushing blocks 321 to move left and right, so that when the push plates 32 on the left and right sides are flipped to the lower part of the enclosure 2 and are in a vertical state, the push plates 32 on the left and right sides drive the bottle pushing blocks 321 to rest against the lower part of the bottle body.

[0067] Specifically, one group of bottle pushing blocks 321 on the left pushing plate 32 rests on the leftmost column of glass bottles, and another group of bottle pushing blocks 321 on the left pushing plate 32 rests on the glass bottles that are staggered in the second column from left to right and the leftmost column of glass bottles. The same applies to the bottle pushing blocks 321 on the right pushing plate 32.

[0068] When the push plates 32 on the front and rear sides are flipped to the lower part of the enclosure 2 and are in a vertical state, the fixing rod 342 moves to the end of the guide groove close to the middle part of the track frame 1, so that the bottle clamping block 33 can no longer move relative to the push plates 32 on the front and rear sides, thereby allowing the push plates 32 on the front and rear sides to push and correct the lower part of the bottle body on the front and rear sides through the bottle clamping block 33.

[0069] At the same time, the push plates 32 on the left and right sides are flipped to the lower part of the enclosure 2 and are in a vertical state, so that the push plates 32 on the left and right sides drive the bottle pushing blocks 321 to rest against the lower part of the bottle body, thereby combining with the limitation of the enclosure 2 on the upper part of the bottle body to form an upper and lower bidirectional clamping force, synchronously correcting the position of the bottle body, effectively eliminating the tilting and non-movement phenomenon caused by the unconstrained lower part of the bottle body, and improving the stacking accuracy.

[0070] Then the push plate 32 is reset, and the enclosure 2 is flipped upward by the electric cylinder, and the track frame 1 is moved to the initial position to facilitate palletizing the glass bottles again. It should be noted that the palletizing area of ​​the glass bottles is provided with an elevator in the prior art, which is not shown in the figure. When the palletizing of one layer of glass bottles is completed, the elevator drives the glass bottle stack to move downward a fixed distance as a whole, so that the glass bottles can be palletized on the glass bottle stack again.

[0071] See Figures 1 to 8 When palletizing glass bottles, the present invention also includes the following steps: the first step is to convey the glass bottle array forward to between the four panels 2 through the existing conveyor belt, control the rear electric cylinder to drive the rear panel 2 to flip downward, so that the four panels 2 are framed on the outside of the glass bottle matrix, and then move the panel 2 to the right.

[0072] In the second step, when the four enclosures 2 drive the glass bottle array to move to the upper part of the supporting plate 42, the rotation of the conveyor belt 422 improves the smoothness of the movement of the glass bottle array to the upper part of the supporting plate 42, reduces the wear on the bottom of the glass bottles, and then drives the four enclosures 2 and the lower bracket 41 to move synchronously to the right to the stacking area through the existing track moving assembly.

[0073] The third step is to control the electric cylinder to weaken the clamping force of the four enclosures 2 on the glass bottle array, move the lower bracket 41 to the left to the initial position, and the conveyor belt 422 quickly pushes the glass bottles on it to the right, so that the glass bottles are close together when unloading. At the same time, the drive motor 431 is started to drive the supporting plate 42 to move back and forth left and right, so that the supporting plate 42 can straighten the crooked glass bottles.

[0074] In the fourth step, the glass bottles fall to the stacking area under the action of gravity, and then the lower bracket 41 drives the carrying plate 42 to move left to the initial position and stops the driving motor 431.

[0075] In the fifth step, the telescopic sections of the two hydraulic push rods 313 at the front and rear positions are extended, so that the two flipping push plates 32 drive the bottle clamping block 33 to lean against the bottle body, and the glass bottle is moved through the cooperation of the fixing rod 342 and the guide groove to prevent the bottle body from getting stuck and not falling completely.

[0076] In the sixth step, the push plates 32 on the left and right sides are flipped to the lower part of the enclosure 2 and are in a vertical state, so that the bottle pushing block 321 and the bottle clamping block 33 are against the lower part of the bottle body. Combined with the limit of the enclosure 2 on the upper part of the bottle body, a bidirectional clamping force is formed in the upper and lower directions to synchronously correct the position of the bottle body and improve the stacking accuracy.

[0077] In the seventh step, the push plate 32 is reset and the enclosure 2 is flipped upward, the track frame 1 is moved to the initial position, and the glass bottle stack is driven by the elevator to move downward a fixed distance as a whole, so that the glass bottles can be stacked on the glass bottle stack again.
