Abstract

The automatic stacking mechanism with the weight protection function comprises a machine frame, and stacking mechanisms are installed on the inner walls of the two sides of the machine frame. A rotating shaft is rotatably mounted on the inner wall of the top of the rack, first bevel gears are fixedly connected to the two ends of the rotating shaft, fixing plates are mounted on the inner walls of the two sides of the rack, and threaded rods are rotatably connected to the tops of the two fixing plates; when the plate stacking machine is used and the infrared transmitting tube and the infrared receiving tube which are symmetrically arranged on the two sides of the interior of the rack operate, the infrared transmitting tube can continuously transmit infrared signals, the infrared receiving tube is used for receiving the infrared signals, and when the height of stacked plates exceeds and shields the infrared signals, the infrared transmitting tube can continuously transmit the infrared signals. When a single chip microcomputer in the touch screen recognizes that signals are interrupted and the height of the stacked plates exceeds a threshold value, the stacking mechanism stops running, so that the stacking weight in the stacking process of the plates is prevented from being too large, and the overweight stacking protection effect is achieved.

Description

Technical Field

[0001] The utility model relates to the technical field of palletizers, and in particular to an automatic palletizing mechanism with weight protection. Background Art

[0002] A palletizer is a device used to stack goods transported along a conveyor line in a pre-set manner. A palletizer is usually composed of a robotic arm, a control system and a conveying system. The control system is responsible for guiding the robotic arm to perform lifting and stacking operations. Palletizers are widely used in manufacturing, logistics, warehousing and other fields. They can improve production efficiency, reduce labor costs, and ensure the accuracy and consistency of cargo stacking.

[0003] However, traditional palletizers lack automatic weight detection and control mechanisms when performing plate stacking operations, and are unable to effectively monitor whether the height of the plate stack exceeds the safety threshold, resulting in excessive stacking during the stacking process, increasing the safety risks of operators and equipment, and may also affect the quality and efficiency of palletizing. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art.

[0005] To this end, one purpose of the utility model is to propose an automatic stacking mechanism with weight protection, which can continuously send and receive infrared signals through an infrared transmitting tube and an infrared receiving tube, judge the stacking height of the plates, and stop the operation of the stacking mechanism in time to prevent excessive accumulation from causing additional weight increase.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic stacking mechanism with weight protection, comprising a frame, wherein the stacking mechanisms are installed on the inner walls on both sides of the frame; a rotating shaft is rotatably installed on the top inner wall of the frame, and both ends of the rotating shaft are fixedly connected to a first bevel gear, and a fixing plate is installed on the inner walls on both sides of the frame, and the tops of the two fixing plates are rotatably connected to a threaded rod, and the tops of the two threaded rods are fixedly connected to a second bevel gear, and every two adjacent first bevel gears and second bevel gears are meshed and connected, and a motor is installed at the bottom of one of the fixing plates, and the rotating shaft of the motor passes through the fixing plate and is fixedly connected to one end of the bottom of the threaded rod, and the outer walls of the two threaded rods are threadedly connected to movable plates, and infrared transmitting tubes and infrared receiving tubes are symmetrically installed on opposite sides of the two movable plates.

[0007] Preferably, the stacking mechanism comprises a rodless cylinder symmetrically mounted on the inner walls of both sides of the frame, a telescopic cylinder is mounted on the rodless cylinder via a slider, and a piston rod of the telescopic cylinder is fixedly connected to a lifting rod.

[0008] Preferably, a touch screen is installed on one side of the frame, and a single-chip microcomputer is integrated inside the touch screen.

[0009] Preferably, the touch screen is electrically connected to the telescopic cylinder and the rodless cylinder through a single-chip microcomputer, and the signal output ends of the infrared transmitting tube and the infrared receiving tube are both connected to the single-chip microcomputer signal inside the touch screen.

[0010] Preferably, at least two cylinders are symmetrically mounted on the bottom inner wall of the frame, damping blocks are slidably mounted inside the cylinders, and springs are mounted on the bottom inner wall of the cylinders.

[0011] Preferably, a cover is installed on the outside of the motor.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: when performing the palletizing operation, the utility model can continuously send infrared signals through the infrared transmitting tube and receive infrared signals through the infrared receiving tube. When the height of the stacked plates exceeds and covers the transmitted infrared signal, it is judged that the stacking gravity exceeds the preset threshold value, so that the single-chip microcomputer in the touch screen recognizes the signal interruption, thereby stopping the operation of the palletizing mechanism in time to prevent the safety hazards caused by excessive stacking. In addition, by starting the motor, the two threaded rods can be driven to rotate, changing the height of the infrared transmitting tube and the infrared receiving tube, and then dynamically adjusting the emission and receiving height of the infrared signal to achieve the threshold adjustment of the palletizing weight protection.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 2 An embodiment of the utility model provides an automatic palletizing mechanism with weight protection, comprising: a frame 1 and a palletizing mechanism installed on the inner walls of both sides of the frame 1.

[0021] Among them, refer to Figure 1 and Figure 3 The stacking mechanism includes a rodless cylinder 14 symmetrically installed on the inner walls of both sides of the frame 1, and a telescopic cylinder 15 is installed on the rodless cylinder 14 through a slider. The piston rod of the telescopic cylinder 15 is fixedly connected with a lifting rod 18. When the stacking mechanism is in use, the inner walls of both sides of the frame 1 start the telescopic cylinder 15 to extend the lifting rod 18 into the bottom of the stacked plate, and lift the plate upward through the rodless cylinder 14, so as to facilitate the movement of the new plate to the bottom of the original stacked plate, thereby completing the stacking operation of the plate.

[0022] Among them, Figure 1 As shown, a rotating shaft 4 is rotatably installed on the inner wall of the top of the frame 1, and both ends of the rotating shaft 4 are fixedly connected to the first bevel gear 5, and fixed plates 2 are installed on the inner walls of both sides of the frame 1, and the tops of the two fixed plates 2 are rotatably connected to the threaded rods 3, and the tops of the two threaded rods 3 are fixedly connected to the second bevel gear 6, and every two adjacent first bevel gears 5 and second bevel gears 6 are meshed and connected, and a motor 11 is installed at the bottom of one of the fixed plates 2, and the rotating shaft of the motor 11 passes through the fixed plate 2 and is fixedly connected to one end of the bottom of the threaded rod 3, and the outer walls of the two threaded rods 3 are threadedly connected with movable plates 7, and infrared transmitting tubes 10 and infrared receiving tubes 9 are symmetrically installed on the opposite sides of the two movable plates 7.

[0023] When the motor 11 is in use, it can drive one of the threaded rods 3 to rotate, and drive the other threaded rod 3 to rotate simultaneously under the transmission of the first bevel gear 5 and the second bevel gear 6, so that the infrared transmitting tube 10 and the infrared receiving tube 9 can adjust the height, thereby realizing the emission and reception height adjustment of the infrared signal.

[0024] Further, see Figure 1 A touch screen 12 is installed on one side of the frame 1, and a single-chip microcomputer is integrated inside the touch screen 12. The touch screen 12 is electrically connected to the telescopic cylinder 15 and the rodless cylinder 14 through the single-chip microcomputer, and the signal output ends of the infrared transmitting tube 10 and the infrared receiving tube 9 are both connected to the single-chip microcomputer signal inside the touch screen 12.

[0025] When the infrared transmitting tube 10 and the infrared receiving tube 9 are in operation, the infrared transmitting tube 10 can continuously send infrared signals and use the infrared receiving tube 9 to receive infrared signals. When the height of the stacked plates exceeds and blocks the infrared signal, the single chip microcomputer in the touch screen 12 can recognize that the signal is interrupted, the height of the stacked plates exceeds the threshold, and the operation of the stacking mechanism is stopped, thereby preventing the stacking weight of the plates from being too large during the stacking process, thereby achieving the function of protecting against overweight stacking.

[0026] like Figure 1 and Figure 4 As shown, at least two cylinders 16 are symmetrically installed on the bottom inner wall of the frame 1, and a damping block 17 is slidably installed inside the cylinder 16. A spring 19 is installed on the bottom inner wall of the cylinder 16. When the plate is lifted and lowered for stacking, the bottom of the plate can contact the damping block 17 on the cylinder 16, and the contraction of the spring 19 can buffer the downward stacking of the plate.

[0027] Specifically, a shield 13 is installed outside the motor 11 , and the shield 13 can cover and protect the motor 11 .

[0028] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when the utility model is used, the inner walls on both sides of the frame 1 start the telescopic cylinder 15 to extend the lifting rod 18 into the bottom of the stacked plate, and lift the plate upward through the rodless cylinder 14, so as to facilitate the movement of the new plate to the bottom of the original stacked plate, thereby completing the stacking operation of the plate.

[0029] When the infrared transmitting tube 10 and the infrared receiving tube 9 symmetrically arranged on both sides of the frame 1 are in operation, the infrared transmitting tube 10 can continuously send infrared signals and use the infrared receiving tube 9 to receive infrared signals. When the height of the stacked plates exceeds and blocks the infrared signal, the single chip microcomputer in the touch screen 12 can recognize the signal interruption, the height of the stacked plates exceeds the threshold, and the operation of the stacking mechanism is stopped, thereby preventing the stacking weight of the plates from being too large during the stacking process, thereby achieving the function of protecting against overweight stacking.

[0030] In addition, by starting the motor 11, one of the threaded rods 3 can be driven to rotate, and the other threaded rod 3 can be driven to rotate simultaneously under the transmission of the first bevel gear 5 and the second bevel gear 6, so that the infrared transmitting tube 10 and the infrared receiving tube 9 can adjust the height, thereby realizing the emission and reception height adjustment of infrared signals. When the height is increased, the stacking plates can be stacked more and the stacking weight is increased. When the height is reduced, the stacking plates can be stacked less and the stacking weight is reduced, thereby realizing the threshold adjustment of the stacking weight protection.

[0031] Parts not involved in the present invention are the same as the prior art or can be implemented by the prior art. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
