[0002] A palletizer is an automated device used to neatly stack items into piles and is widely applied in industries such as manufacturing, logistics, and warehousing. The palletizer can greatly improve production efficiency, reduce manual labor intensity, and ensure the stability and accuracy of stacking. It is one of the indispensable automated devices in modern industrial production, capable of significantly enhancing production efficiency and work safety. With the development of automation technology, palletizers are also constantly evolving, becoming more intelligent, efficient, and flexible.

[0003] In the prior art, when a palletizer stacks bagged items, it is necessary to place a pallet on a roller conveyor device, and then place the bagged items on the pallet through the palletizer. The pallet may be subjected to the force of the bagged items and slide and shift, which may lead to uneven stacking. Moreover, when the bagged items are stacked to a certain height, tipping may occur, resulting in a reduction in the stacking efficiency of the bagged items. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems existing in the prior art that when a palletizer stacks bagged items, it is necessary to place a pallet on a roller conveyor device, and then place the bagged items on the pallet through the palletizer. The pallet may be subjected to the force of the bagged items and slide and shift, which may lead to uneven stacking. Moreover, when the bagged items are stacked to a certain height, tipping may occur, resulting in a reduction in the stacking efficiency of the bagged items.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: an anti - tipping structure for a palletizer, comprising: a roller conveyor device and a palletizer body. The palletizer body is arranged on one side of the roller conveyor device, and further comprises:

[0006] Two first fixing blocks are symmetrically and fixedly installed at the bottom of the roller conveyor device close to the palletizer body. A bidirectional lead screw is movably embedded on the opposite sides of the two first fixing blocks. Threaded bars are sleeved on the outer surfaces of the two ends of the bidirectional lead screw. On the sides of the two threaded bars away from the bidirectional lead screw, movable rods are fixedly installed. Two second fixing blocks are symmetrically and fixedly installed at the top of the roller conveyor device close to the palletizer body. The inner walls of the two second fixing blocks are respectively movably sleeved on the outer surfaces of the two movable rods. Clamping plates are fixedly installed at one ends of the two movable rods. A square plate is fixedly installed on one side of the palletizer body close to the bottom. A first motor is fixedly installed on one side of the square plate. The output end of the first motor is fixedly installed at one end of the bidirectional lead screw.

[0007] Preferably, two guide rods are symmetrically and fixedly installed on the top of each of the two clamping plates. The multiple guide rods are evenly divided into two groups. A plurality of first baffles are arranged above each of the two clamping plates. The bottoms of two of the first baffles are respectively fixedly installed on the tops of the two clamping plates, and the interiors of the other first baffles are respectively movably sleeved on the outer surfaces of the two groups of guide rods. Through the arrangement of the first baffles, it is convenient to block the bagged items on the tray.

[0008] Preferably, a plurality of iron chains are equidistantly and fixedly installed on one side between every two adjacent first baffles. A limit ring is fixedly sleeved at one end of each of the multiple guide rods. Through the arrangement of the iron chains, when the upper first baffle moves upward, the iron chains can be straightened and apply a pulling force to the lower first baffle. Through the arrangement of the limit rings, a certain limiting effect is achieved.

[0009] Preferably, a square block is fixedly installed on one side of each of the multiple first baffles. Electric telescopic rods are fixedly installed on the tops of two of the square blocks. One ends of the two electric telescopic rods are respectively fixedly installed on the bottoms of the other two square blocks. Two of the square blocks are respectively connected to the two bottommost first baffles, and the other two square blocks are respectively connected to the two topmost first baffles. By controlling the electric telescopic rods to start through a controller, they are extended to apply an upward thrust to the upper square block, synchronously driving the topmost first baffle to slide upward along the outer surface of the guide rod.

[0010] Preferably, mounting blocks are fixedly installed on the opposite sides of two of the first baffles. A rotating rod is movably embedded in the top of each of the multiple mounting blocks. Motors two are fixedly installed on the bottoms of the multiple mounting blocks. The output ends of the multiple motors two are respectively fixedly installed on one ends of the multiple rotating rods. By controlling the motors two to start through a controller, the output shafts drive the rotating rods to rotate.

[0011] Preferably, connecting blocks are fixedly installed on the opposite sides of the other first baffles. The multiple connecting blocks are evenly divided into multiple groups. The inner walls of the multiple groups of connecting blocks are respectively movably sleeved on the outer surfaces of the multiple rotating rods. Through the above arrangement, the rotating rods can rotate with the connecting blocks and can also slide up and down.

[0012] Preferably, a plurality of second baffles are slidably connected to the outer surfaces of the multiple rotating rods. One ends of the multiple second baffles are respectively movably embedded in the opposite sides of the two arms of the multiple connecting blocks. Through the above arrangement, the second baffles can slide up and down along the rotating rods and cannot rotate.

[0013] Preferably, a plurality of protrusions are fixedly installed on the opposite sides of the two clamping plates. Through the arrangement of the protrusions, the function of increasing friction is achieved, thereby improving the stability of the clamping plates for clamping and fixing the tray.

[0014] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0015] In the present utility model, when the controller controls the first motor to start, the output shaft thereof drives the bidirectional lead screw to rotate. Then, under the action of the threaded engagement between the bidirectional lead screw and the threaded bar, and with the cooperation of the movable rod for limiting and guiding the threaded bar, the threaded bar can move towards the middle along the outer surface of the bidirectional lead screw, simultaneously pushing the movable rod and the clamping plate to move towards both sides of the tray, and clamping and fixing the tray through the clamping plate. With the cooperation of the protrusions, a certain frictional force can be increased, making the clamping more stable. In this way, when the palletizing machine body places the bagged items on the tray, the tray can be prevented from sliding and shifting, thereby avoiding the situation of uneven palletizing.

[0016] In the present utility model, when the controller controls the second motor to start, the output shaft thereof drives the rotating rod to rotate, simultaneously driving the second baffle to rotate 90 degrees to block the other two sides of the tray. The second baffle can slide up and down along the rotating rod and cannot rotate. Then, when the controller controls the electric telescopic rod to start and extend, an upward thrust is applied to the upper square block, simultaneously driving the uppermost first baffle to slide upward along the outer surface of the guide rod. With the cooperation of the iron chain, when the uppermost first baffle rises to a certain height, the iron chain connected thereto is in a straightened state and applies a pulling force to the lower first baffle. Repeating this process, the adjustment can be followed according to the stacking height of the bagged items. Simultaneously, through the movement of the first baffle, the connecting block can be driven to move, and a pushing force is applied to the second baffle through the connecting block, enabling the second baffle to slide upward along the outer surface of the rotating rod. In this way, the adjustment can be made according to the stacking height of the bagged items on the tray, so that the first baffle and the second baffle can block the bagged items, thereby preventing the bagged items from tipping over and improving the stacking efficiency of the bagged items.

With the cooperation of the protrusions, a certain amount of friction can be increased, making the clamping more stable. In this way, when the palletizer body 2 places the bagged items on the tray, the tray can be prevented from sliding and shifting, thus avoiding the situation of uneven palletizing.

[0027] Embodiment 2, as Figures 1 to 4 shown, two guide rods 4 are symmetrically and fixedly installed at the tops of the two clamping plates 304. The multiple guide rods 4 are evenly divided into two groups. A plurality of first baffles 401 are arranged above the two clamping plates 304. The bottoms of two of the first baffles 401 are respectively fixedly installed at the tops of the two clamping plates 304, and the interiors of the other multiple first baffles 401 are respectively movably sleeved on the outer surfaces of the two groups of guide rods 4.

Multiple second baffles 503 are slidably connected to the outer surfaces of the multiple rotating rods 501. One ends of the multiple second baffles 503 are respectively movably embedded on the opposite sides of the two arms of the multiple connecting blocks 504.

[0029] Working principle: When in use, first place the tray on top of the roller conveyor device 1 and push the tray between the two clamping plates 304. At this time, control the motor 1 306 to start through the controller, and its output shaft drives the bidirectional lead screw 301 to rotate.

In this way, when the palletizer body 2 places the bagged items on the tray, the tray can be prevented from sliding and shifting, thus avoiding the situation of uneven palletizing. Then, control the height of the first baffle 401 according to the stacking height of the bagged items. Control the motor 2 502 to start through the controller, and its output shaft drives the rotating rod 501 to rotate, simultaneously driving the second baffle 503 to rotate 90 degrees to block the other two sides of the tray. The second baffle 503 can slide up and down along the rotating rod 501 and cannot rotate. Then, control the electric telescopic rod 405 to start through the controller, and make it extend to apply an upward thrust to the upper square block 404, simultaneously driving the uppermost first baffle 401 to slide upward along the outer surface of the guide rod 4. With the cooperation of the iron chain 403, when the uppermost first baffle 401 rises to a certain height, the iron chain 403 connected to it is in a straightened state and applies a pulling force to the lower first baffle 401. Repeating this way, it can be adjusted following the stacking height of the bagged items. Simultaneously, through the movement of the first baffle 401, the connecting block 504 can be driven to move, and a pushing force is applied to the second baffle 503 through the connecting block 504, enabling the second baffle 503 to slide upward along the outer surface of the rotating rod 501. In this way, it can be adjusted according to the stacking height of the bagged items on the tray, so that the first baffle 401 and the second baffle 503 block the bagged items, thus preventing the bagged items from tipping over, and further improving the stacking efficiency of the bagged items.
