Description

Technical Field

[0001] The invention relates to a conveying device, in particular to a subassembly and boxing conveying device. Background Art

[0002] In the process of realizing the automated production of bottled beverages, due to process requirements, the beverage box will be placed in the mold box. After the packaging of the beverage box is completed, the finished beverage box is grabbed out of the mold box using a suction cup mechanism. Most existing mechanisms use mechanical claws to grab the beverage box from the mold box, but the use of mechanical claws has the following disadvantages: first, the mechanical claws need to have a certain amount of space to move, resulting in the need to leave a gap between adjacent mold boxes, which makes the entire conveying device less compact; second, the mechanical claw grabbing method requires squeezing the side wall of the beverage box to have sufficient friction, which will cause the beverage box to deform and cause damage to the product. Therefore, the beverage box is replaced by a suction cup suction method to grab the beverage box from the mold box. However, due to the pressure between the beverage box and the mold box, the friction between the two is also relatively large. The suction cup suction method requires a large suction force and may cause the top cover or diaphragm on the top of the beverage box to separate from the bottle body. Summary of the Invention

[0003] The object of the present invention is to provide a subassembly and boxing conveying device that can effectively solve the problem that existing conveying devices require suction cups to generate large suction force when separating beverage boxes from mold boxes, which easily causes damage to products.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: a group-packing and conveying device, comprising a frame and multiple rows of parallel conveying rails arranged on the frame, multiple mold boxes are placed on each row of the conveying rails, each of the mold boxes is cylindrical and has an open top, the frame is provided with a blocking mechanism to control the movement or stillness of the mold box, and according to the direction of movement of the mold box, a jacking mechanism is fixed on the bottom of the frame upstream of the blocking mechanism, the jacking mechanism includes a jacking frame, a jacking plate, a jacking drive mechanism and multiple jacking rods, the jacking frame is fixed on the frame below the conveying guide rail, the jacking drive mechanism is arranged on the jacking frame, the jacking plate is driven vertically by the jacking drive mechanism, multiple jacking rods are fixed on the jacking plate, the positions of the jacking rods correspond one to one to the mold boxes above them, the conveying guide rails are provided with a channel for the jacking rod to pass through, and the bottom of each mold box is provided with a jack for inserting the jacking rod.

[0005] Preferably, the lifting mechanism further comprises a pair of slide rails and a transverse drive mechanism. The pair of slide rails are fixed to the lifting frame and parallel to the direction of movement of the mold box. The slide rails are provided with a movable plate. The lifting drive mechanism is fixed to the movable plate. The transverse drive mechanism is fixed to the lifting frame, and the transverse drive mechanism drives the movable plate to slide along the slide rails. By providing the transverse drive mechanism, the offset distance of the lifting rod in the direction of movement of the mold box is controlled, thereby adjusting the position of the lifting rod below the mold box. On the other hand, the number of beverage boxes ejected simultaneously can be adjusted to correspond exactly to the number of suction cups.

[0006] Preferably, the transverse drive mechanism includes a transverse drive motor, a transverse screw, and a transverse screw sleeve. The transverse drive motor is fixed to the lifting frame, the transverse screw is rotatably connected to the lifting frame, the transverse drive motor drives the transverse screw to rotate, the transverse screw sleeve is threadedly engaged with the transverse screw, and the movable plate is fixedly connected to the transverse screw sleeve. Through the cooperation of the transverse screw and the transverse screw sleeve, the transverse movement distance of the lifting rod can be more accurately controlled, allowing the lifting rod to accurately pass through the mold box and eject the beverage box.

[0007] Preferably, four first sliding sleeves are fixed to the movable plate, and four first sliding rods are fixed to the lifting plate. The four first sliding rods correspond to and slideably engage with the four first sliding sleeves. The sliding rods and the sliding sleeves cooperate to control the movement direction of the lifting plate, allowing it to move in a straight line when the lifting rod is lifted. Furthermore, the four sliding rods cooperate with the four sliding sleeves to ensure that deflection does not occur during the lifting operation.

[0008] Preferably, each lifting rod comprises a rod body and a support plate, wherein the bottom of the rod body is fixed to the lifting plate, and the support plate is fixed to the top of the rod body. The rod body serves as a connection, while the support plate can increase the contact area with the bottom of the beverage box to prevent the bottom of the beverage box from being deformed or broken during lifting.

[0009] Preferably, the blocking mechanism includes a blocking frame, a blocking plate, and a blocking driver. The blocking frame is fixed to the frame, and the blocking driver is fixed to the blocking frame. The blocking driver drives the blocking plate to intercept the mold box on the conveyor rail. The blocking driver controls the operation of the blocking plate to simultaneously block the mold boxes on multiple conveyor rails, thereby achieving the purpose of synchronously controlling the operating status of the mold boxes on multiple conveyor rails.

[0010] Preferably, two second sliding sleeves are fixed to the blocking frame, and two second sliding rods are connected to the blocking plate. The two second sliding rods correspond to and slide with the two second sliding sleeves in a one-to-one manner. The sliding direction of the second sliding rods is parallel to the direction in which the blocking plate is driven by the blocking driver. The second sliding rods cooperate with the second sliding sleeves to control the blocking frame to move smoothly along a straight line, thereby blocking the mold box in a straight line and facilitating its alignment with the suction cup mechanism.

[0011] Preferably, the blocking actuator is a blocking actuator cylinder comprising a cylinder body and a piston, the cylinder body being fixed to the blocking frame, the piston being fixedly connected to a connecting plate, and the connecting plate being fixedly connected to the two second slide bars. By controlling the movement of the blocking plate through the driving cylinder, the air source is relatively inexpensive to obtain. The blocking plate is aligned with the second slide bars, with the driving cylinder providing power, the slide bars limiting the direction of movement, and the connecting plate evenly transmitting the power of the driving cylinder to the two second slide bars, which is then transmitted to the blocking plate via the second slide bars, thereby enabling the blocking plate to maintain smooth linear motion.

[0012] Preferably, the blocking driver drives the blocking plate to move in a direction that forms an obtuse angle with the direction of movement of the mold boxes, thereby blocking the mold boxes at an obtuse angle, thereby facilitating the separation of two adjacent rows of mold boxes.

[0013] Compared with the prior art, the advantages of the present invention are: a lifting mechanism is provided below the conveyor rail, which solves the problem of high friction between the beverage box and the mold box, making it difficult to grasp the beverage box using a suction cup. A blocking mechanism is used to block the mold box on the conveyor rail, keeping it relatively still. Then, a lifting drive mechanism is used to operate a lifting plate to lift multiple lifting rods upward, thereby ejecting the beverage box from the corresponding mold box. When the suction cup sucks up the beverage box, it only needs to overcome the gravity of the beverage box itself. The provision of the lifting mechanism greatly facilitates the demoulding of the beverage box, while reducing the suction force required by the suction cup. When the suction cup sucks the beverage box, it also avoids pulling and separating the bottle cap or membrane from the bottle body, thus ensuring the integrity of the product.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0028] See Figures 1 to 4 This is an embodiment of a packaged box conveyor device according to the present invention. The packaged box conveyor device includes a frame 100 and multiple rows of parallel conveyor rails 110 disposed on the frame 100. In this embodiment, there are five rows of conveyor rails 110, each of which is equipped with multiple mold boxes 120. The mold boxes 120 are simply placed on the conveyor rails 110 and driven by friction. Each row of conveyor rails 110 includes two tracks with a gap between the two tracks, which is equivalent to the mold boxes 120 being mounted on two tracks. To ensure that the mold boxes 120 do not deviate, guide bars are provided on the side walls of each conveyor rail 110 to ensure that the gap between the mold boxes 120 and the side walls of the conveyor rails 110 is as small as possible. Each mold box 120 is cylindrical and matches the shape of the beverage box. Each mold box 120 has a socket at the bottom to facilitate ejecting the beverage box from the bottom of the mold box 120.

[0029] The assembly and box conveying device also includes a blocking mechanism 200 and a lifting mechanism 300. The blocking mechanism 200 is used to control the movement or stillness of the mold box 120, that is, to control whether the mold box 120 continues to run with the conveying guide rail 110, and the lifting mechanism 300 is mainly used to push out from the bottom the beverage box in the mold box 120 that is blocked by the blocking mechanism 200 and is in a prohibited state. Therefore, the lifting mechanism 300 is set on the frame 100 below the conveying guide rail 110 upstream of the blocking mechanism 200.

[0030] The lifting mechanism 300 includes a lifting frame 310, a lifting plate 320, a lifting drive mechanism 330 and multiple lifting rods 340. The lifting frame 310 is fixed on the frame 100. The lifting drive mechanism 330 does not have very strict requirements on the lifting height, so it can be a cylinder, a hydraulic cylinder or an electric cylinder. The cylinder body of the lifting drive mechanism 330 is fixed on the lifting frame 310, the lifting plate 320 is fixed on the piston of the lifting drive mechanism 330, and the lifting rods 340 are fixed on the top surface of the lifting plate 320. The arrangement and spacing of the lifting rods 340 are consistent with the arrangement and spacing of the mold box 120 above it, that is, one lifting rod 340 corresponds to one mold box 120. When the lifting drive mechanism 330 is started, the lifting rod 340 is lifted into the jack at the bottom of the mold box 120 to eject the beverage box from the mold box 120. Each lifting rod 340 includes a rod body 341 and a supporting plate 342. The bottom of the rod body 341 is fixed on the lifting plate 320, and the supporting plate 342 is fixed on the top of the rod body 341. Since the lifting rod 340 pushes the beverage box out of the mold box 120 from the bottom, it contacts the bottom of the beverage box through the supporting plate 342, thereby increasing the contact area and preventing the lifting rod 340 from piercing the beverage box during the lifting process.

[0031] Since the number of the lifting rods 340 on the lifting plate 320 is fixed, Figure 6 As shown, the lifting rods 340 are currently arranged in eight rows and five columns, but the packing quantity of different products is different. In other words, some products do not need to suck up eight rows of beverage cups at a time. In this case, the number of beverage cups lifted at a time needs to be adjusted. Therefore, the lifting mechanism 300 also includes a pair of slide rails 350 and a transverse drive mechanism 360. The pair of slide rails 350 are fixed to the lifting frame 310 and are arranged along the conveying direction of the mold box 120. A movable plate 370 is slidably set on the slide rails 350. The movable plate 370 is driven by the transverse drive mechanism 360 to move along the slide rails 350, and the lifting drive mechanism 330 is fixed to the movable plate 370. In this way, the effective lifting quantity of the lifting rods 340 at a time can be controlled, as shown in FIG. Figure 5 As shown, if the distance between two adjacent rows of lifting rods 340 is taken as a standard distance, then in the state shown in the figure, the transverse drive mechanism 360 controls the lifting plate 320 to move three standard distances in the moving direction of the mold box 120, that is, at this time there will be three rows of lifting rods 340 located behind the blocking mechanism 200, that is, three rows of lifting rods 340 will not work, and after the lifting drive mechanism 330 drives the lifting plate 320 to rise, five rows and five columns of beverage boxes will be lifted from the mold box 120.

[0032] Furthermore, in order to more accurately control the lateral movement distance, the lateral movement drive mechanism 360 includes a lateral movement drive motor 361, a lateral movement screw 362 and a lateral movement screw sleeve 363. The lateral movement drive motor 361 is fixed on the lifting frame 310, and the lateral movement screw 362 is rotatably connected to the lifting frame 310, and its axial direction is parallel to the length direction of the slide rail 350. The lateral movement drive motor 361 drives the lateral movement screw 362 to rotate, and the lateral movement screw sleeve 363 is threadedly connected to the lateral movement screw 362. The movable plate 370 is fixedly connected to the lateral movement screw sleeve 363, so that the movable plate 370 is driven by the rotation of the lateral movement screw 362. By using the cooperation between the lateral movement screw 362 and the lateral movement screw sleeve 363, the moving distance of the movable plate 370 can be accurately controlled to ensure that after the movable plate 370 moves, the lifting rod 340 can also be aligned with the socket of the mold box 120.

[0033] During the process of the lifting drive mechanism 330 driving the lifting plate 320 to rise and fall, it is necessary to ensure that the lifting rod 340 is in a straight up and down movement mode. The movable plate 370 is generally rectangular, and a first sliding sleeve 380 is fixed on each of the four corners of the movable plate 370, and a first sliding rod 390 corresponding to the first sliding sleeve 380 is set on the four corners of the lifting plate 320. Through the cooperation of the first sliding sleeve 380 and the first sliding rod 390, the movement trajectory of the lifting plate 320 is restricted to ensure that the lifting rod 340 can go straight up and down.

[0034] The blocking mechanism 200 mainly blocks the mold box 120 on the conveying guide rail 110 so that it no longer moves with the conveying guide rail 110, thereby ensuring that the lifting rod 340 can smoothly penetrate and move out of the mold box 120. The blocking mechanism 200 includes a blocking frame 210, a blocking plate 220 and a blocking driver 230. The blocking frame 210 is in the shape of a door, spanning above the conveying guide rail 110 and fixed on the frame 100. The blocking driver 230 is fixed on the crossbeam of the blocking frame 210, and the blocking plate 220 is driven by the blocking driver 230 to block the running line of the mold box 120. Two second sleeves 240 are also fixed on the blocking frame 210, and the two second sleeves 240 are respectively located on both sides of the blocking driver 230. Two second slide bars 250 are connected to the blocking plate 220, and the two second slide bars 250 slide with the corresponding second sleeves 240. By utilizing the cooperation of the second slide bars 250 and the second sleeves 240, the blocking driver 230 is a blocking drive cylinder, which includes a cylinder body 231 and a piston 232. The cylinder body 231 is fixed on the blocking frame 210, and the piston 232 is fixedly connected to the connecting plate 260. The connecting plate 260 is fixedly connected to the two second slide bars 250. The driving force of the blocking driver 230 is better transmitted to the two second slide bars 250 through the connecting plate 260, and then the thrust is transmitted to the blocking plate 220 through the second slide bars 250. The blocking plate 220 is restricted to a linear trajectory, and the blocking plate 220 is perpendicular to the conveying direction of the mold box 120. This allows the mold box 120 to maintain a uniform resting position after being blocked, facilitating suction by the suction cup mechanism, and also aligning with the lift rods 340 of the lift mechanism 300. The blocking plate 220 can be reversed in a vertical, downward direction, perpendicular to the direction of movement of the mold box 120. However, this approach would subject the second slide bar 250 and the blocking actuator 230 to significant lateral forces, potentially causing deformation and affecting the normal operation of the blocking plate 220. Therefore, the present invention sets the blocking plate 220's reverse movement at an obtuse angle to the direction of movement of the mold box 120, that is, obliquely inserting the blocking plate 220 to block the mold box 120. This increases the lateral forces on the second slide bar 250 and the blocking actuator 230 and reduces their lateral deformation range.

[0035] During use, the number of beverage boxes that need to be sucked up is determined according to the packing requirements, and then the transverse drive motor 361 drives the transverse screw 362 to transfer, driving the movable plate 370 to move laterally to an appropriate distance, and controlling the number of beverage boxes that can be lifted up in one lift to be equal to the number of beverage boxes that can be sucked up. When the operation officially starts, the conveying guide rail 110 drives the mold box 120 to move, and the blocking driver 230 drives the blocking plate 220 to block the mold box 120 obliquely downward. Blocked by the blocking plate 220, the mold box 120 is in a stationary state relative to the frame 100. At this time, the lifting drive mechanism 330 is started, driving the lifting plate 320 to move upward with the lifting rod 340. The lifting rod 340 is inserted into the mold box 120 from the jack at the bottom of the mold box 120, lifting the beverage box from the bottom, so that the beverage box and the mold box 120 are in a stationary state. After the empty mold boxes 120 are moved out from under the blocker, the blocking driver 230 is started again to make the blocking plate 220 block the mold box 120 with the beverage box, and the above process is repeated, and the above process is repeated. After the assembly and box conveying device of the present invention is adopted, before the suction cup mechanism sucks the beverage box, the lifting mechanism 300 can be used to separate the beverage box from the mold box 120, thereby eliminating the friction between the beverage box and the mold box 120, avoiding the suction cup mechanism from pulling the beverage box after sucking the beverage box, and making the suction process smoother.

[0036] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in this field within the scope of the present invention are included in the patent scope of the present invention.
