Description

Technical Field

[0001] The utility model relates to the technical field of palletizers, and more specifically, to a box feeding device for a palletizer. Background Art

[0002] A palletizer automatically stacks cardboard and plastic boxes, such as those already packed in containers, onto pallets in a specific arrangement. The stacking process can occur in multiple layers, and then the palletizer pushes the boxes out for forklift transport to the warehouse for storage. During the case-feeding operation, the palletizer may tilt, resulting in unstable gripping, which can prevent items from entering the sealed boxes and reduce work efficiency.

[0003] After searching, the Chinese patent with announcement number CN219565629U discloses a box feeding mechanism for a palletizer. Through the setting of the grabbing mechanism, the items can be adsorbed without causing additional damage to the items. By starting the cylinder, the suction cup is driven down to the top of the items inside the storage box. The internal environment of the suction cup is changed to vacuum through the vacuum pump, so that it adsorbs and completes the grabbing, avoiding the occurrence of empty grabbing or accidents.

[0004] When the above-mentioned carton feeding mechanism is in use, the cartons are transported through the conveying device. However, during the process of placing the cartons, the cartons will not always be located at the top center position of the conveying device. When the carton deviates from the top center position of the conveying device, it is difficult to clamp the carton subsequently, and it is inconvenient to limit and guide the carton, resulting in poor use effect. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a case feeding device for a palletizer, which aims to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a palletizer box feeding device, comprising a mounting plate and a transmission belt, and the transmission belt is fixedly mounted on the top of the mounting plate, and a support frame is fixedly connected to the top of the mounting plate and located at the outer position of the transmission belt, and a limiting assembly is arranged inside the support frame, and the limiting assembly comprises a screw rod, two sliders, four extrusion sleeves and two baffles, the front and rear ends of the screw rod are fixedly connected to the support frame, the two sliders and the four extrusion sleeves are movably mounted on the screw rod, and one side of the four extrusion sleeves are respectively in contact with the front and rear sides of the two sliders.

[0007] Furthermore, both ends of the two sliding blocks are fixedly connected to limit plates, and one side of the four limit plates respectively extends into both sides of the support frame.

[0008] It can be seen that in the above technical solution, the slider drives the two limit plates to move in the support frame to prevent the slider from deflecting.

[0009] Furthermore, bolts are movably provided on the two sliders, and the two sliders are fixed to the two baffles by two fastening bolts respectively.

[0010] It can be seen that in the above technical solution, another baffle is placed on top of one of the baffles, and the other baffle is fixed to the slider by bolts, and the length of the baffle is extended as needed.

[0011] Furthermore, two clamping blocks are fixedly connected to opposite sides of the two baffles, and one side of the four clamping blocks extends into the two sliding blocks respectively.

[0012] It can be seen that in the above technical solution, the stability between the baffle and the slider is improved.

[0013] Furthermore, the bottom end of the mounting plate is fixedly connected to a column, the column is movably connected to a connecting frame through a bearing, a self-locking motor is fixedly connected to the center position of the inner bottom end of the connecting frame, and the output shaft end of the self-locking motor is fixedly connected to the column.

[0014] Furthermore, the bottom end of the connecting frame is fixedly connected to a hydraulic cylinder, the bottom end of the hydraulic cylinder is fixedly connected to a bottom plate, and the bottom end of the bottom plate near the four corners is fixedly connected to universal wheels.

[0015] It can be seen that in the above technical solution, pushing the connecting frame can drive the four universal wheels to slide on the ground, thereby driving the mounting plate and the transmission belt to move horizontally.

[0016] Furthermore, the top of the bottom plate is fixedly connected to telescopic rods near the four corners, and the tops of the four telescopic rods are fixedly connected to the connecting frame.

[0017] It can be seen that in the above technical solution, the four telescopic rods extend and retract following the hydraulic cylinder, thereby improving the stability of the connecting frame.

[0018] Technical effects and advantages of this utility model:

[0019] 1. The utility model uses two baffles to limit and guide the carton, and makes the carton located at the top center of the transmission belt. The extrusion sleeve is rotated and moved away from the slider, and the slider is moved horizontally to drive the baffle to move horizontally. Similarly, the slider is squeezed and limited by the two extrusion sleeves. The distance between the two blocks is adjusted according to the size of the carton. The operation is simple, the carton can be easily limited and guided, and the use effect is good.

[0020] 2. The utility model extends the piston rod on the hydraulic cylinder to drive the connecting frame to move upward, thereby driving the mounting plate and the transmission belt to move upward.
