Description

Technical Field

[0001] The invention belongs to the technical field of juice production and packaging, and in particular relates to a stacking conveying and packaging device for vacuum fresh-keeping juice production. Background Art

[0002] Vacuum-preserved juices are generally filled in glass bottles, plastic-coated cartons and aluminum cans during production. For example, glass bottles need to be boxed after filling and capping, stacked and palletized, and finally transported to a designated location. When boxing, a liner needs to be placed in the carton to separate and fix the bottles to prevent them from colliding and moving with each other during transportation, thereby protecting the product from damage.

[0003] Currently, there are two ways to install the liner: manual placement or robotic placement. Manual placement is less efficient. Although the robotic placement method improves the placement efficiency, when the robotic arm places the liner, the liner moves downward under the action of the robotic arm and is put outside the bottle. Since there may be errors in the movement of the robotic arm, the center of the hole on the liner and the center of the bottle may deviate when the liner moves downward and is put outside the bottle. As a result, the edge of the hole on the liner is squeezed and deformed by the bottle when the liner moves downward, and severe cases may cause damage to the edge of the hole on the liner. This will cause a gap between the hole on the liner and the bottle body. When the carton is subsequently transported, the bottle may shake, thereby increasing the risk of bottle damage.

[0017] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0018] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0019] As Figure 1-Figure 4 shown, a stacking conveyor packaging device for vacuum-preserved fruit juice production includes a first conveying mechanism 13 for conveying the bottle body 4, a second conveying mechanism 14 for conveying the inner lining 7, a third conveying mechanism 15 for conveying the carton 16, an operating table 3 and a pushing mechanism 8. The device further includes: A centering cylinder 2. There is a mounting frame 11 above the operating table 3. The bottom of the mounting frame 11 is installed with a fifth telescopic member 12. The output end of the fifth telescopic member 12 is installed with a top plate 1. The bottom of the top plate 1 is installed with a plurality of centering cylinders 2. The bottom ends of the centering cylinders 2 are sleeved outside the bottle body 4. A clamping mechanism 6. The bottom of the mounting frame 11 is installed with a driving member 5. The output end of the driving member 5 is provided with a turntable 51. The periphery of the turntable 51 is installed with a plurality of groups of clamping mechanisms 6. The clamping mechanism 6 is used to clamp the inner lining 7. When one group of clamping mechanisms 6 clamps the inner lining 7 and moves to the lower part of the plurality of centering cylinders 2, the plurality of centering cylinders 2 move downward through a plurality of circular holes on the inner lining 7 through the fifth telescopic member 12.

[0020] Furthermore, the straightening cylinder 2 comprises a cylinder body 21 , a conical hole 28 is formed inwardly at the bottom end of the cylinder body 21 , and the bottle body 4 is inserted into the conical hole 28 for straightening.

[0021] Further, a plurality of arc plates 23 are installed on the periphery of the cylinder 21, a plurality of wedge blocks 231 are arranged on the inner side of the arc plates 23, the wedge blocks 231 penetrate the cylinder 21, a fixing rod 22 is fixedly arranged in the cylinder 21, a plurality of elastic members 232 are arranged on the periphery of the fixing rod 22, the other end of the elastic member 232 penetrates the cylinder 21 and is connected to the arc plates 23, a connecting member 25 is installed in the cylinder 21, and the connecting member 25 includes a connecting plate 251, a connecting rod 25 2 and connecting plate 2 253, a plurality of connecting rods 252 are connected between connecting plate 1 251 and connecting plate 2 253, a plurality of conical rings 26 are arranged on the plurality of connecting rods 252, the inclined surface of conical ring 26 coincides with the inclined surface of wedge block 231, the top end of connecting plate 1 251 is connected with telescopic member 1 24, telescopic member 1 24 is mounted on top plate 1, the bottom end of connecting plate 2 253 is connected with connecting column 254, and clamping assembly 27 is mounted on connecting column 254.

[0022] Furthermore, the clamping assembly 27 includes a fixing ring 271, which is fixed on the inner wall of the cylinder 21. The connecting column 254 passes through the fixing ring 271. One end of the connecting column 254 is hinged with a plurality of clamping claws 273. The outer periphery of the fixing ring 271 is hinged with a plurality of connecting rods 272, and the other end of the connecting rod 272 is hinged with the clamping claw 273.

[0023] It should be noted that the hollowed-out part on the side of the lining 7 moves in alignment with the clamping mechanism 6, making it convenient for the clamping mechanism 6 to clamp the lining; the plurality of connecting rods 252 do not contact the plurality of elastic members 232 and the fixed parts of the fixing rod 22, so that the connecting member 25 is not interfered by the elastic member 232 and the fixed parts of the fixing rod 22 when moving.

[0024] In one case of this embodiment, the telescopic member 24 and the telescopic member 12 can both be cylinders; the driving member 5 can be a motor; the elastic member 232 can be an elastic telescopic rod, or other elastically telescopic components.

[0025] In actual application of this embodiment, the neatly arranged bottles 4 are conveyed to the operating table 3 by the conveying mechanism 1 13, and the baffle 31 on the operating table 3 blocks the bottles 4. The liner 7 is conveyed to the clamping mechanism 6 by the conveying mechanism 2 14 and clamped. Then, the turntable 51 is rotated by the driving member 5, so that the clamping mechanism 6 holding the liner 7 is rotated to the bottom of the plurality of straightening cylinders 2. At this time, the driving member 5 is turned off and locked, and then the plurality of straightening cylinders 2 are driven to move downward by the telescopic member 5 12 and the top plate 1. The straightening cylinder 2 moves downward and passes through the hole on the liner 7. The bottom of the straightening cylinder 2 is also sleeved on the top plate 1. The outer surface of the bottle body 4 is contacted by the conical hole 28, and the position of the bottle body 4 can be corrected, so that the central axis of the bottle body 4 coincides with the central point of the hole on the liner. At this time, the clamping mechanism 6 releases the liner 7, and the liner 7 moves down under the action of gravity and is sleeved on the outside of the bottle body 4. In this way, the liner 7 can be smoothly sleeved on the outside of the bottle body 4, which can effectively avoid mechanical stress from damaging the edge of the hole on the liner 7, thereby effectively avoiding a gap between the hole on the liner 7 and the bottle body 4, and effectively avoiding the shaking of the bottle body 4 during transportation, thereby reducing the risk of damage to the bottle body 4 during transportation; When the straightening cylinder 2 passes through the hole on the liner 7, the connecting member 25 is driven upward by the telescopic member 24, so that the conical ring 26 on the connecting member 25 slowly squeezes the wedge blocks 231 on the inner sides of the arc plates 23, so that the wedge blocks 231 move outward, thereby moving the arc plates 23 outward, and the arc plates 23 slowly abut against the holes on the liner 7, and cooperate with the straightening cylinder 2 to straighten the bottle body 4, further making the center axis of the bottle body 4 coincide with the center line point of the hole on the liner, so that the liner 7 can be smoothly sleeved on the outside of the bottle body 4, further effectively avoiding mechanical stress on the edge of the hole on the liner 7 The arc plate 23 abuts against the hole on the liner 7 to keep the liner 7 in a horizontal state, effectively preventing the liner 7 from being slightly bent when being clamped, so that the center axis of the bottle body 4 can be further coincided with the center point of the hole on the liner; in addition, the arc plate 23 abuts against the hole on the liner 7, which can correct the part of the edge of the hole on the liner 7 that is originally bent or creased, thereby effectively avoiding a gap between the hole on the liner 7 and the bottle body 4, effectively preventing the bottle body 4 from shaking during transportation, thereby reducing the risk of damage to the bottle body 4 during transportation; When the arc plate 23 abuts against the hole on the liner 7, the telescopic member 24 drives the connecting member 25 to move upward, and the connecting column 254 on the connecting member 25 moves upward, so that the clamping claw 273 rotates inward and clamps the surface of the bottle body 4, ensuring that the bottle body 4 does not move, improving the stability of the bottle body 4, and avoiding external vibrations that cause the bottle body 4 to shake. It can ensure that the central axis of the bottle body 4 always coincides with the center line point of the hole on the liner, so that the liner 7 can be smoothly put on the outside of the bottle body 4.

[0026] like Figure 5As shown, a through hole 233 is longitudinally opened in the arc plate 23, one end of the through hole 233 is connected to an air supply pipe 234, and the air supply pipe 234 is connected to an external air supply unit. A plurality of downwardly inclined air outlet holes 235 are opened on the outer surface of the arc plate 23, and the plurality of air outlet holes 235 are arranged at equal intervals longitudinally, and the air outlet holes 235 are connected to the through hole 233. A downwardly inclined air outlet hole 236 is opened at the bottom of the arc plate 23, and the air outlet hole 236 is connected to the through hole 233.

[0027] In one aspect of this embodiment, the external air supply unit may be an air pump.

[0028] In actual application of this embodiment, when it is necessary to put the liner 7 on the straightening cylinder 2 on the outside of the bottle body 4, the external air supply unit introduces gas into the through hole 233 through the air supply pipe 234, and the gas is discharged through a plurality of air outlet holes 235 and air outlet holes 236. Since the air outlet holes 1 235 and the air outlet holes 2 236 are inclined downward, the blown air flow will blow the top of the liner 7, so that the liner 7 slowly moves downward, and with the deadweight of the liner 7, the liner 7 can be smoothly put on the outside of the bottle body 4, which can effectively prevent mechanical stress from damaging the edges of the holes in the liner 7.

[0029] like Figure 6 and Figure 7 As shown, the clamping mechanism 6 includes: Positioning plate 64, a plurality of ear plates 61 are arranged on the periphery of the turntable 51, a fixing plate 62 is fixed on the other side of the ear plate 61, a telescopic member 2 63 is installed on the other side of the fixing plate 62, and a positioning plate 64 is installed on the output end of the telescopic member 2 63; A movable plate 65 is movably mounted on the other side of the positioning plate 64; A diagonal plate 68 and a fixed block 66 are provided on the other side of the movable plate 65. Telescopic parts three 67 are installed at the four corners of the fixed block 66. The output end of the telescopic part three 67 is installed with a diagonal plate 68. The diagonal plate 68 is in a right-angle state. When clamping the lining 7, the four diagonal plates 68 rest against the four diagonals on the inner side of the lining 7.

[0030] In one case of this embodiment, both the telescopic member 2 63 and the telescopic member 3 67 can be cylinders. In actual application of this embodiment, the conveying mechanism 2 14 transports the lining 7 toward the clamping mechanism 6. In the initial state, the size of the rectangle formed by the four diagonal plates 68 is smaller than the size of the rectangle formed by the hollow part of the lining 7. In this way, the lining 7 is sleeved on the four diagonal plates 68 under the action of inertia. At this time, the four telescopic members 3 67 are extended to make the four diagonal plates 68 move outward and press against the four diagonals on the inner side of the lining 7, thereby clamping the lining 7. Clamping the lining 7 in this way can effectively prevent the lining 7 from bending, so that the upper and lower holes of the lining 7 coincide with each other, which is convenient for the subsequent straightening cylinder 2 to pass through the hole on the lining 7.

[0031] Further, a slider 69 is provided on the movable plate 65, and a third chute 642 is formed on the positioning plate 64. The slider 69 is slidably installed in the third chute 642, and an elastic member three 645 is connected between the slider 69 and the third chute 642.

[0032] Further, a second chute 641 is formed at the top of the positioning plate 64. The second chute 641 communicates with the third chute 642. A U-shaped plate 643 is slidably installed in the second chute 641. Half of the U-shaped plate 643 is located in the second chute 641, and the other half of the U-shaped plate 643 is located outside the positioning plate 64. Both ends of the U-shaped plate 643 are wedge-shaped. A clamping groove 691 is formed on one side of the slider 69. One end of the U-shaped plate 643 passes through the second chute 641 and is clamped in the clamping groove 691. An elastic member two 644 is connected between the U-shaped plate 643 and the second chute 641. A trigger member 17 is provided on the top plate 1. The bottom end of the trigger member 17 is wedge-shaped. The wedge-shaped surface at the bottom end of the trigger member 17 coincides with the wedge-shaped surface at one end of the U-shaped plate 643. A wedge-shaped platform 10 is provided on the operating table 3. The top end of the wedge-shaped platform 10 is flush with the bottom end of the movable plate 65. The wedge-shaped platform 10 is located in the rotation direction of the movable plate 65.

[0033] In one case of this embodiment, both the elastic member two 644 and the elastic member three 645 can be springs.

[0034] During the actual application of this embodiment, when the top plate 1 drives several centering cylinders 2 to move downward, the trigger member 17 also moves downward accordingly. The trigger member 17 gradually contacts one end of the U-shaped plate 643 and causes the U-shaped plate 643 to move slowly, compressing the elastic member two 644, and causing the other end of the U-shaped plate 643 to move out of the clamping groove 691. In this way, the restriction on the slider 69 is released, causing the slider 69 to drive the movable plate 65 to move downward, thereby driving the inner liner 7 to move downward. Together with the self-weight of the inner liner 7 and the air flow blown out from the first air outlet 235 and the second air outlet 236, the inner liner 7 can be smoothly sleeved outside the bottle body 4. During the downward movement of the slider 69, the elastic member three 645 is compressed, which can prevent the slider 69 from moving too fast during the downward movement, thereby avoiding damage to the inner liner 7. During the downward movement of the inner liner 7, the second telescopic member 63 and several third telescopic members 67 contract, causing the diagonal plate 68 to gradually move away from the inner liner 7, enabling the inner liner 7 to move downward by its own weight and avoiding damage to the inner liner 7 driven by the diagonal plate 68. After the inner liner 7 is installed, the driving member 5 drives the turntable 51 to continue rotating, and the clamping mechanism 6 also rotates. During the rotation, the bottom of the movable plate 65 contacts the wedge-shaped platform 10, causing the movable plate 65 to move upward slowly, thereby causing the slider 69 to move upward and squeeze the U-shaped plate 643, causing one end of the U-shaped plate 643 to be tightly clamped in the clamping groove 691, and causing the movable plate 65 to return to its original position.

[0035] Such as Figure 2 、 Figure 8and Fig. 9 As shown, an auxiliary mechanism 9 is installed on the operating table 3, and the auxiliary mechanism 9 includes two rotating rods 91. Two slide grooves 32 are symmetrically opened on the operating table 3. The rotating rod 91 is movably sleeved in the slide groove 32. An elastic member 911 is connected between the rotating rod 91 and the slide groove 32. An auxiliary plate 92 is elastically rotatably installed outside the rotating rod 91. The auxiliary plate 92 rotates around the rotating rod 91 into the carton 16. When the auxiliary plate 92 rotates 90 degrees, the auxiliary plate 92 fits against the inner wall of the carton 16. Pull-back blocks 921 are provided on the opposite sides of the two auxiliary plates 92. The pushing mechanism 8 includes a telescopic member 4 81. A push plate 82 is installed at the output end of the telescopic member 81. When the push plate 82 pushes a number of bottles 4 and the liner 7 into the carton 16, the push plate 82 is resisted by the two pull-back blocks 921.

[0036] In one case of this embodiment, the telescopic member four 81 can be a cylinder, the elastic member four 911 can be a spring, and the rotating part of the auxiliary plate 92 is provided with a torsion spring, so that the auxiliary plate 92 is always in a parallel state with the carton 16 in the initial state.

[0037] In actual application of this embodiment, after the liner 7 is installed outside the plurality of bottle bodies 4, the push plate 82 is driven to move by the telescopic member 81, so that the push plate 82 contacts the liner 7 and pushes the plurality of bottle bodies 4 toward the carton 16. During the movement, the front end of the liner 7 contacts the two auxiliary plates 92, so that the two auxiliary plates 92 rotate toward the carton 16. Through the guidance of the two auxiliary plates 92, the plurality of bottle bodies 4 together with the liner 7 can easily enter the carton 16. The two auxiliary plates 92 will slowly rotate until they are in contact with the inner wall of the carton 16. At this time, the auxiliary plates 92 cannot be taken out, and the carton 16 cannot move along the conveying mechanism 3 15. When the bottles 4 and the liner 7 are completely put into the carton 16, the pull-back blocks 921 on the two auxiliary plates 92 are against the push plate 82. At this time, the telescopic member 4 81 is contracted, so that the push plate 82 slowly returns to its original position. In this way, the push plate 82 will drive the two pull-back blocks 921 to move, so that the two auxiliary plates 92 move outward, and the rotating rod 91 moves in the slide groove 1 32 to compress the elastic member 4 911. When the two auxiliary plates 92 are completely moved out of the carton 16, the elastic member 4 911 and the torsion spring have the resilience to make the auxiliary plates 92 rotate to their initial state, and the rotating rod 91 returns to its original position. It should be noted that, since the auxiliary plate 92 is inserted into the carton 16 and a number of bottles 4 together with the liner 7 are placed in the carton 16, when the auxiliary plate 92 moves out of the carton 16, there is a gap on both sides of the liner 7. Here, the thickness of the auxiliary plate 92 is set to a state where the gap formed cannot move the liner 7; in addition, when the push plate 82 pushes a number of bottles 4 together with the liner 7, the two auxiliary plates 92 are in a slowly rotating state, and at this time the push plate 82 is not blocked by the two pull-back blocks 921.
