Description

Technical Field

[0001] The utility model belongs to the field of carton stacking and packing, in particular to a carton stacking and palletizing device. Background Art

[0002] The cartons used for pharmaceutical packaging are often thin, rectangular, and flat. After packaging, they are typically transported by conveyor belts to the packing station, where workers manually stack and pack them. This method is labor-intensive and, due to the high speed of the equipment, requires two people to complete the task, resulting in high labor costs. Packing is also done entirely by workers counting, which creates the risk of overpacking or underpacking.

[0003] Chinese patent CN210594282U discloses a pharmaceutical palletizer conveying device, comprising: a feed conveyor belt, a packaging box conveyor belt, a discharge conveyor belt, a purifier, a detection box, a counting display, a controller, a lifting column, a cylinder, a movable block, a baffle and a support column; the feed conveyor belt and the discharge conveyor belt are connected by a movable fastener; the packaging box conveyor belt is vertically arranged on the feed conveyor belt and is arranged at a position between the purifier and the detection box; the counting display is arranged on the detection box; and the controller is arranged on the support column at the lower end of the detection box.

[0004] This patent tilts the discharge conveyor belt at a certain angle to the horizontal direction. Every time the lifting column rises a certain distance, the packaging boxes transmitted from the discharge conveyor belt are stacked in sequence. The packaging boxes obtained in this way are easily offset, resulting in the stacked packaging boxes being neither neat nor standard, and still requiring secondary sorting and processing.

[0029] like Figure 1-Figure 7 As shown, the utility model provides a carton stacking and palletizing device, comprising: a frame 1, a conveyor belt 2, a carton lifting assembly 3, a carton receiving frame 4, multiple pairs of check assemblies 5, a pair of second cylinders 6, and a third cylinder 7.

[0030] like Figure 1-Figure 2 As shown, the frame 1 includes a base 11 and legs 12; the conveyor belt 2 is mounted on the frame 1 and surrounds the top and bottom surfaces of the base 11 of the frame 1. The conveyor belt 2 can continuously transport cartons 9, facilitating subsequent stacking and palletizing of the cartons 9. Guide rails 8 are mounted on the base 11 of the frame 1 and are symmetrically arranged on both sides of the conveyor belt 2, effectively preventing the cartons 9 on the conveyor belt 2 from shifting.

[0031] like Figure 2-Figure 3As shown, the carton lifting assembly 3 is located below the frame 1 and includes a first cylinder 31 and a lifting bracket 32. The lifting bracket 32 includes two side plates and a bottom plate 45. The two side plates are located on both sides of the conveyor belt 2. The first cylinder 31 is fixed to the frame 1. The movable end of the first cylinder 31 is connected to the bottom plate 45 of the lifting bracket 32. The two side plates of the lifting bracket 32 pass through the sides of the conveyor belt 2 from below the frame 1. When the carton lifting assembly 3 of the present invention is in operation, the lifting bracket 32 is raised by the extension and retraction of the first cylinder 31, and the rising lifting bracket 32 lifts the carton 9 on the conveyor belt 2.

[0032] like Figure 2-Figure 3 As shown, a pair of second cylinders 6 are fixed on both sides of the carton accommodating rack 4, and the non-return assembly 5 has a fixed non-return assembly 501 and a movable non-return assembly 502. Specifically, there are two pairs of fixed non-return assemblies 501, and there is a pair of movable non-return assemblies 502, which are located between the two pairs of fixed non-return assemblies 501. The movable end of the second cylinder 6 is connected to the movable non-return assembly 502. When the second cylinder 6 contracts upward, it drives the movable non-return assembly 502 and the paper boxes 9 on the movable non-return assembly 502 to move upward. After the number of stacked paper boxes 9 reaches a certain level, the second cylinder 6 drives the movable non-return assembly 502 and the stacked paper boxes 9 to lift upward a certain distance, leaving enough buffer space and time for subsequent stacking, thereby greatly improving the operating efficiency of the device. As shown Figure 2 As shown, the third cylinder 7 is located behind the carton rack 4. Optionally, the third cylinder 7 is mounted on the rear plate 44 of the carton rack 4 via a support plate 48. The movable end of the third cylinder 7 is connected to a push plate 49, which pushes the carton 9 from the rear of the carton rack 4 through the push plate's movable hole 40 to the front of the carton rack 4. The third cylinder 7 of the present invention moves, pushing the carton 9 lifted by the second cylinder 6 into the second storage space of the carton rack 4. This allows staff to remove the standardized stacked cartons for packing, improving the efficiency of carton packing.

[0033] like Figure 4-Figure 5As shown, the carton storage rack 4 is fixed on the top surface of the base 11 of the frame 1, and the rear portion of the carton storage rack 4 has a push plate movable hole 40. In a specific embodiment, the carton storage rack 4 includes a first side panel 41, a second side panel 42, a front panel 43, a back panel 44 and a bottom panel 45. The first side panel 41, the second side panel 42 and the back panel 44 constitute a first storage space for stacking the carton 9. The first side panel 41, the front panel 43 and the bottom panel 45 constitute a second storage space for placing the carton 9 pushed out from the first storage space. The utility model realizes the lifting and stacking of the carton 9 in the first storage space of the carton storage rack 4 in advance, and then pushes the carton 9 in the first storage space to the second storage space, so that the stacked carton 9 is neat and standard, which is convenient for subsequent packing. Among them, the bottom panel 45 of the carton storage rack 4 is made with a semicircular notch 46 to reduce the difficulty of taking the carton 9 and facilitate the packing of the carton 9. The paper box receiving frame 4 further has a baffle 47 , which is connected to the first side plate 41 and the second side plate 42 and can effectively prevent the paper box 9 from overflowing.

[0034] like Figure 3 、 Figure 6 、 Figure 7 As shown, each pair of check assemblies 5 is distributed on both sides of the paper box accommodating frame 4. When the paper box 9 passes through the check assemblies 5, the check assemblies 5 contract. After the paper box 9 has completely passed through the check assemblies 5, the check assemblies 5 extend, and the paper box 9 falls onto the top surface of the check assemblies 5. Specifically, the check assemblies 5 include a check seat 51, a spring 52, and a check dial block 53. The spring 52 is installed in the check seat 51, and one end is connected to the check dial block 53. The check dial block 53 is an arc-shaped block. When the check dial block 53 is squeezed laterally, the check dial block 53 enters the check seat 51 by compressing the spring 52 in the check seat 51. The check assemblies 5 of the present invention can allow the paper box 9 to pass through, and extend when the paper box 9 reaches the top of the check assemblies 5 to prevent the paper box 9 from falling back, thereby gradually realizing the cumulative stacking of multiple paper boxes 9 and completing the preliminary stacking and palletizing.

[0035] In addition, the cylinders of the present carton stacking and palletizing device can be controlled by sensors, programmable controllers, human-machine interfaces and other components. Cartons 9 are transported to the inside of the device through the conveyor belt 2, and the information of the carton 9 being in place is provided to the programmable controller through the sensor. The first cylinder 31 rises, passes through the non-return assembly 5 and stacks upward, and the parameters are set. When the number of cartons stacked upward is reached, the second cylinder 6 pulls upward to leave enough free time for subsequent stacking. After the pulling is completed, the third cylinder 7 is actuated to push out a certain number of cartons 9. The staff takes away the stacked cartons for packing, thereby improving the packing efficiency. This device can set the number of stacks and the parameters of each cylinder. When the conveyor belt 2 transports the cartons 9 to the specified position, the sensor receives the signal and gives the cylinder an instruction to move. The number of stacks can also be calculated through the programmable controller, and the number of counts is more accurate to avoid the occurrence of too many or too few boxes.

[0036] The method of using this carton stacking and palletizing device is as follows:

[0037] The cartons 9 are continuously transported by the conveyor belt 2 and arrive at the carton lifting assembly 3. The first cylinder 31 of the carton lifting assembly 3 extends and contracts to raise the lifting bracket 32. The rising lifting bracket 32 lifts the carton 9 on the conveyor belt 2. When the carton 9 passes through the non-return assembly 5, the non-return assembly 5 contracts. After the carton 9 completely passes through the non-return assembly 5, the non-return assembly 5 extends, and the carton 9 falls onto the top surface of the non-return assembly 5, gradually accumulating multiple carton 9. When the carton 9 reaches a sufficient number, the second cylinder 6 drives the movable non-return assembly 502 and the stacked carton 9 to lift upward, and then the third cylinder 7 extends to push the carton 9 lifted by the second cylinder 6 to the second storage space of the carton storage rack 4.

[0038] The utility model utilizes the non-return component 5 to prevent the carton 9 from falling back, gradually realizes the cumulative stacking of multiple carton 9, completes the preliminary stacking and palletizing, and realizes the lifting and stacking of the carton 9 by the first cylinder 31, realizes the overall lifting of the stacked carton 9 by the second cylinder 6, and leaves enough buffer space and time for subsequent stacking, and pushes the carton 9 to the second accommodating space of the carton accommodating rack 4 by the third cylinder 7, which is convenient for taking out and packing the carton 9. The multiple cylinders cooperate with each other to complete the stacking and palletizing of the carton 9, with a high degree of automation and standardization, which can effectively improve the sorting efficiency of carton packing.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
