Description

Technical Field

[0001] The present invention relates to the technical field of glass bottle warehousing, and specifically to a glass bottle positioning and palletizing mechanism. Background Art

[0002] As a packaging container widely used in industries such as food, beverage, and medicine, glass bottles require efficient and stable palletizing operations during production, storage, and transportation. Neat palletizing can not only improve the utilization rate of warehousing space but also reduce collisions and breakages during transportation, ensuring product quality.

[0003] Currently, common glass bottle palletizing equipment usually includes a baffle structure and a supporting plate structure that move along a track. The equipment drives the baffle to move to the periphery of the glass bottle matrix through a track frame. As shown in the glass bottle matrix Figure 8 The bottle group is framed and fixed as a whole. Subsequently, the baffle and the supporting plate below cooperate to move, and the glass bottle group is transported to the target palletizing area. After reaching the designated position, the baffle remains stationary, and the supporting plate resets to the initial position. The glass bottles fall layer by layer to the palletizing area due to the loss of support.

[0004] However, the existing equipment still has two deficiencies: First, during the falling stage of the glass bottles, in order to avoid the bottle body getting stuck due to the continuous clamping of the baffle, the baffle needs to release the restraint on the bottle body in advance, resulting in the lack of lateral limit for the glass bottles during the falling process, and they are prone to tilt, affecting the neatness and stability of palletizing.

[0005] Second, when the glass bottles have completely fallen, the baffle needs to correct the position of the skewed 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 and it is difficult to apply a uniform thrust, resulting in limited correction effect. When the lower part of the bottle body is not effectively constrained, the bottle may only tilt without moving, further reducing the palletizing accuracy. Summary of the Invention

[0006] To solve the above technical problems, the technical solution adopted by the present invention is: A glass bottle positioning and palletizing mechanism includes a track frame that moves left and right along a track. Four baffles controlled by electric cylinders are hinged to the lower part of the track frame. A bottle pushing unit for correcting the position of the glass bottles is commonly provided on the four baffles. The mechanism also includes a pallet unit for supporting and discharging the glass bottles.

[0007] The bottle pushing unit includes a pushing plate that is arranged on the baffle through a flipping assembly and is used to push the lower part of the glass bottle body after falling. Clamping blocks that contact the bottle body are equidistantly arranged in the left - right direction on the front and rear pushing plates. When the clamping blocks contact the bottle body, the bottle body is pushed to move left and right through a guiding assembly.

[0008] The pallet unit includes a lower bracket that slides left and right on the track. A bearing plate is slidably arranged left and right on the upper side of the lower bracket. A reciprocating assembly for driving the bearing plate to sway left and right relative to the lower bracket is jointly provided at the rear sides of the lower bracket and the bearing plate.

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

[0010] Preferably, the guiding assembly includes sliding frames arranged at equal intervals in the left-right direction on the front and rear pushing plates. The sliding frames are slidably connected to the pushing plates left and right. A bottle clamping block is slidably connected to the inside of the sliding frame. A helical spring is arranged between the bottle clamping block and the sliding frame.

[0011] Preferably, fixing rods are fixedly installed at equal intervals in the left-right direction on the front and rear pushing plates. The fixing rods correspond to the sliding frames one by one. A guiding groove with continuous bends is formed on the bottle clamping block. The fixing rods slide inside the guiding groove.

[0012] Preferably, two groups of bottle pushing blocks are slidably arranged left and right on both the left and right pushing plates. The two groups of bottle pushing blocks are arranged in a front-back dislocation manner. Synchronous plates are jointly fixedly installed on the sides of the bottle pushing blocks in the same group away from the enclosure plate. The bottle pushing blocks are locked to the pushing plates through fastening screws.

[0013] Preferably, the left parts of the lower bracket and the bearing plate have slopes with the same inclination. The right part of the lower bracket has an inclined surface structure. The lower part below the right part of the bearing plate is a vertical surface, and the upper part is an inclined surface with the same slope as the inclined surface of the right part of the lower bracket.

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

[0015] Preferably, two rotation rollers are rotatably arranged symmetrically left and right inside the bearing plate. A conveyor belt is wound between the two rotation rollers. The front end of the right rotation roller is connected to a gear through a ratchet structure. A rack is slidably arranged up and down at the front end on the right side of the track.

[0016] Preferably, a U-shaped plate is slidably arranged up and down in front of the bearing plate and corresponding to the outside of the gear. Teeth for locking the rotation of the gear are arranged on the upper side of the horizontal section of the U-shaped plate. A compression spring is arranged between the U-shaped plate and the bearing plate.

[0017] Preferably, an electric push rod for driving the rack to move up and down is fixedly installed at the front side of the track. A lower pressing plate is fixedly installed at 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 by 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 clamping block on the push plate acts accurately on the lower part of the glass bottle body, and combined with the limiting position of the upper part of the bottle body by the surrounding plate, a bidirectional clamping force is formed up and down, and the position of the bottle body is corrected synchronously, breaking through the limitation of the surrounding plate in the prior art that can only push the upper part 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.

[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 reciprocate left and right 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 block, it can adapt to glass bottles of different diameters.

Detailed implementation manners

[0032] The embodiments of the present invention will be described in detail below. The described embodiments are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention. For those without specific technical or conditions noted in the embodiments, they shall be carried out according to the techniques or conditions described in the literature in this field or according to the product specifications.

[0033] Refer to Figure 1 , Figure 2 and Figure 5 , a glass bottle positioning and palletizing mechanism, including a track frame 1 that moves left and right along a track 5. Four enclosing plates 2 are hinged to the lower part of the track frame 1 and are controlled by electric cylinders. A bottle pushing unit 3 for correcting the positions of glass bottles is commonly provided on the four enclosing plates 2. The mechanism further includes a pallet unit 4 for supporting and discharging glass bottles.

[0034] In the initial state, the four enclosing plates 2 are located at the left part of the track 5, and the four enclosing plates 2 are located at the left part of the pallet unit 4.

[0035] It should be noted that the glass bottles are conveyed forward through an existing conveyor belt. The four enclosing plates 2 are all arranged above the front part of the conveyor belt, and the enclosing plate 2 at the rear part is turned upward under the control of the corresponding electric cylinder, so that the conveyor belt drives the glass bottles to move between the four enclosing plates 2. After a certain number of glass bottles between the four enclosing plates 2 are reached, the electric cylinder at the rear part is controlled to drive the enclosing plate 2 at the rear part to turn downward, so that the four enclosing plates 2 are framed outside the glass bottle matrix, and the glass bottle matrix is limited by the enclosing plates 2.

[0036] Subsequently, move the track rack 1 to the right along the track 5, so that the track rack 1 drives the glass bottle matrix to move to the upper part of the pallet unit 4 through the four enclosing plates 2. Then, the pallet unit 4 and the four enclosing plates 2 move to the right synchronously to the stacking area. After that, the positions of the four enclosing plates 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 in a reciprocating motion manner, so that the glass bottles fall in a vertical state and close to each other. When the pallet unit 4 moves to the initial position, the pushing unit 3 cooperates with the four enclosing plates 2 to push and correct the glass bottle array, so that the glass bottles are arranged close to each other, ensuring the stability of the glass bottle stacking.

[0038] Refer to Figure 1 and Figure 2 As shown in, the pallet unit 4 includes a lower bracket 41 that slides left and right on the track 5. A bearing plate 42 is slidably arranged on the upper side of the lower bracket 41 left and right. A reciprocating component 43 for driving the bearing plate 42 to sway left and right relative to the lower bracket 41 is jointly arranged at the rear sides of the lower bracket 41 and the bearing plate 42.

[0039] Refer to Figure 2 and Figure 4 As shown in, the left parts of the lower bracket 41 and the bearing plate 42 are slopes with the same slope, the right part of the lower bracket 41 is of an inclined plane structure, the lower part below the right part of the bearing plate 42 is a vertical plane, and the upper part is an inclined plane with the same slope as the inclined plane of the right part of the lower bracket 41.

[0040] In the initial state, the bearing plate 42 is located at the central position of the upper part of the lower bracket 41, so that the slopes of the left parts of the lower bracket 41 and the bearing plate 42 are arranged coplanarly. At the same time, the inclined plane of the right part of the bearing plate 42 is coplanar with the inclined plane of the right part of the lower bracket 41.

[0041] When the four enclosing plates 2 push the glass bottle array to move to the right, the rightmost row of glass bottles in the glass bottle array first contacts the slope of the left part of the lower bracket 41, so that the glass bottles move upward along the slope of the left part of the lower bracket 41. Subsequently, the rightmost row of glass bottles contacts the slope of the left part of the bearing plate 42, and then the glass bottles move along the slope of the left part of the bearing plate 42 to the upper part of the bearing plate 42.

[0042] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in, two rotation rollers 421 arranged symmetrically left and right are rotatably arranged inside the bearing plate 42. A conveyor belt 422 is wound between the two rotation rollers 421. The front end of the right rotation roller 421 is connected with a gear 423 through a ratchet structure. A rack 424 is slidably arranged up and down at the front end on the right side of the track 5.

[0043] Refer to Figure 3 , a U-shaped plate 425 is slidably arranged up and down on the front side of the bearing plate 42 and corresponding to the outside of the gear 423. Teeth for locking the rotation of the gear 423 are arranged on the upper side of the horizontal section of the U-shaped plate 425. A compression spring is arranged between the U-shaped plate 425 and the bearing plate 42.

[0044] Refer to 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 pressing plate 427 is fixedly installed on the rear side of the rack 424.

[0045] It should be noted that as Figure 1 shown, the track 5 in this embodiment is divided into upper and lower parts, and both are in a plate-like structure. 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. Both the lower bracket 41 and the track frame 1 are provided with sliding power through existing track moving assemblies.

[0046] As Figure 3 shown, the ratchet structure in this embodiment includes a ratchet fixedly installed at the front end of the right rotating roller 421. The gear 423 is rotatably connected to the front end of the right rotating roller 421. Pawls cooperating with the ratchet are equally spaced and hinged inside the gear 423. A torsion spring is arranged 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, otherwise it does not drive the rotating roller 421 to rotate.

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

[0048] When the four enclosing plates 2 drive the glass bottle array to move to the upper part of the bearing 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. Furthermore, the conveyor belt 422 drives the rotating roller 421 to rotate clockwise, improving the smoothness of the glass bottle array moving to the upper part of the bearing plate 42 and reducing the wear on the bottom of the glass bottles.

[0049] Subsequently, through the existing track moving assembly, the four enclosing plates 2 and the lower bracket 41 are driven to move to the right synchronously. The lower bracket 41 drives the glass bottle array to move synchronously through the bearing 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 the extended state, so that the electric push rod 426 drives the rack 424 to be located above the bearing plate 42. When the glass bottle array moves to the stacking area, the telescopic section of the electric push rod 426 is contracted, so that the electric push rod 426 drives the rack 424 to move downward, and the rack 424 drives the lower pressing plate 427 to move downward synchronously.

[0051] It should be noted that the lower side of the lower pressing plate 427 is located below the teeth of the rack 424, so that the lower pressing plate 427 first contacts the upper side 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] Refer to Figure 1 、 Figure 2 and Figure 4 As shown in FIGS.

[0053] After the rack 424 engages with the gear 423, the clamping force of the four enclosing plates 2 on the glass bottle array is weakened by controlling the electric cylinder to prevent the glass pieces from abutting against each other and getting stuck. Then, the lower bracket 41 is moved to the left to the initial position, and at the same time, the driving motor 431 is started to drive the crank disk 432 to rotate, so that the crank disk 432 reciprocates the bearing plate 42 left and right through the spring telescopic plate 433, so that the bearing plate 42 reciprocates left and right relative to the lower bracket 41.

[0054] When the lower bracket 41 moves to the left, the positions of the four enclosing plates 2 remain unchanged, so that the positions of the four enclosing plates 2 pushing the glass bottle array remain unchanged, so that the lower bracket 41 moves to the left relative to the glass bottle array. When the bearing plate 42 moves to the left relative to the lower bracket 41, the bearing plate 42 no longer supports a row of glass bottles on its right part, so that a row of glass bottles on the right part of the bearing plate 42 fall onto the lower bracket 41.

[0055] Moreover, when the bearing plate 42 moves to the left relative to the lower bracket 41, the bearing plate 42 superimposes the leftward movement of the lower bracket 41, so that the bearing plate 42 moves rapidly to the left relative to the rack 424. The bearing 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 quickly pushes the glass bottles on it to the right, so that the glass bottles are close together when being discharged.

[0056] When the carrier plate 42 moves to the right relative to the lower bracket 41, the carrier plate 42 pushes the glass bottles on its right through the vertical surface on its right, so that the cylindrical surface of the glass bottle abuts against the vertical surface on the right of the carrier plate 42, thereby straightening the skewed glass bottle. Moreover, through the contraction and buffering of the spring telescopic plate 433, it can prevent the driving force of the carrier plate 42 on the glass bottle from being too large and causing the glass bottle to break.

[0057] When the lower bracket 41 moves to the left until it no longer blocks the glass bottle, the glass bottle falls to the stacking area under the action of gravity, thereby discharging the glass bottles column by column until all the glass bottles fall to the stacking area. Subsequently, the lower bracket 41 drives the carrier plate 42 to move to the initial position to the left and stops the driving motor 431.

[0058] Refer to Figure 1 、 Figure 5 and Figure 6 As shown in

[0059] Refer to Figure 1 、 Figure 5 and Figure 7 As shown in

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

[0061] Refer to Figure 5 and Figure 6 As shown in

[0062] Refer to Figure 6Fixed rods 342 are fixedly installed on the push plates 32 on the front and rear sides at equal intervals in the left and right directions. The fixed rods 342 correspond to the sliding frames 341 one by one. 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 clamping block 33 by its own elastic force, so that the bottle clamping 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 front and rear flipping pushing plates 32 drive the bottle clamping block 33 to lean against the bottle body, the pushing plate 32 pushes the bottle body through the bottle clamping 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 clamping block 33 pushes the glass bottle in the direction away from the middle of the track frame 1, so that the bottle clamping block 33 drives the guide groove thereon to move synchronously, so that the fixed rod 342 drives the bottle clamping block 33 and the sliding frame 341 to move back and forth horizontally by pushing the guide groove, so that the bottle clamping block 33 moves the glass bottle to prevent the bottle body from getting stuck and not falling completely.

[0065] See also Figure 5 , Figure 7 and Figure 8 Two groups of bottle pushing blocks 321 are slidably arranged 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 one 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 plurality of bottle pushing blocks 321 arranged at equal intervals along the front and rear 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 abuts against the leftmost column of glass bottles, and another group of bottle pushing blocks 321 on the left pushing plate 32 abuts against the glass bottles that are staggered in the second column from left to right and the leftmost column of glass bottles, and the same applies to the bottle pushing blocks 321 on the right pushing plate 32.

[0068] When the pushing plates 32 on the front and rear sides are flipped to the lower part of the surrounding plate 2 and are in the vertical state, the fixing rod 342 moves to the end of the guiding groove close to the middle side of the track frame 1, so that the bottle clamping block 33 can no longer move relative to the pushing plates 32 on the front and rear sides, thereby enabling the pushing plates 32 on the front and rear sides to push and correct the lower parts of the bottle bodies on the front and rear sides through the bottle clamping blocks 33.

[0069] At the same time, flip the pushing plates 32 on the left and right sides to the lower part of the surrounding plate 2 and in the vertical state, so that the pushing plates 32 on the left and right sides drive the bottle pushing blocks 321 to abut against the lower parts of the bottle bodies, thereby combining with the limitation of the upper parts of the bottle bodies by the surrounding plate 2 to form an up-and-down bidirectional clamping force, synchronously correcting the positions of the bottle bodies, effectively eliminating the inclination and non-movement phenomenon caused by the lack of restraint of the lower parts of the bottle bodies, and improving the palletizing accuracy.

[0070] Subsequently, reset the pushing plates 32. At the same time, flip the surrounding plate 2 upward through the electric cylinder and move the track frame 1 to the initial position to facilitate palletizing the glass bottles again. It should be noted that there is a lift in the prior art in the palletizing area of the glass bottles, and the lift is not shown in the figure. After a layer of glass bottles is palletized, the whole stack of glass bottles is driven by the lift to move downward by a fixed distance to facilitate palletizing the glass bottles on the stack of glass bottles again.

[0071] Refer to Figures 1 to 8 , when palletizing the glass bottles, the present invention further includes the following steps: First step, convey the glass bottle array forward to between the four surrounding plates 2 through the existing conveyor belt, control the electric cylinder at the rear to drive the surrounding plate 2 at the rear to flip downward, so that the four surrounding plates 2 are framed outside the glass bottle matrix, and then move the surrounding plate 2 to the right.

[0072] Second step, when the four surrounding plates 2 drive the glass bottle array to move to the upper part of the bearing plate 42, improve the smoothness of the movement of the glass bottle array to the upper part of the bearing plate 42 by the rotation of the conveyor belt 422, reduce the wear on the bottoms of the glass bottles, and then drive the four surrounding plates 2 and the lower bracket 41 to move to the right synchronously to the palletizing area through the existing track moving assembly.

[0073] Third step, weaken the clamping force of the four surrounding plates 2 on the glass bottle array by controlling the electric cylinder, 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 being unloaded. At the same time, start the driving motor 431 to drive the bearing plate 42 to move left and right reciprocally, so that the bearing plate 42 straightens the skewed glass bottles.

[0074] Fourth step, the glass bottles fall to the palletizing area under the action of gravity. Subsequently, the lower bracket 41 drives the bearing plate 42 to move to the left to the initial position and stops the driving motor 431.

[0075] The fifth step is to extend the telescopic sections of the two hydraulic push rods 313 at the front and rear positions, 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] The sixth step is to flip the push plates 32 on the left and right sides to the lower part of the enclosure 2 and place them 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, and combined with the limiting effect of the enclosure 2 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 to improve the stacking accuracy.

[0077] In the seventh step, the push plate 32 is reset and the enclosure plate 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 as to stack the glass bottles on the glass bottle stack again.

[0078] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations on the present invention. A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention and they are still covered by the protection scope of the present invention.
