Description

Technical Field

[0001] The utility model relates to the technical field of vehicle loading machinery, in particular to a packaging box conveying mechanism of a walking type vehicle loading machine. Background Art

[0002] When products leave the factory, they are often packaged in boxes, which are made of a variety of materials, such as paper, wood, and plastic. Boxes are easy to use and transport, and the packaging is reliable, safe, and low-cost. They are widely used in various industries. However, there are many disadvantages when loading boxes.

[0003] For example, after conventional packaging boxes are delivered to a truck compartment manually or by a conveyor belt, they need to be manually removed from the conveyor belt and stacked layer by layer in the compartment. Stacking at a higher position requires the use of ladders or forklifts, requiring the cooperation of multiple operators. This is not only inefficient and labor-intensive, but also wastes limited human resources. Furthermore, this method of stacking packaging boxes can easily lead to damage to the contents due to improper operation, resulting in unnecessary property losses.

[0004] Therefore, replacing manual loading with automated loading equipment has become a growing trend in the logistics industry. A walking loader is an automated device equipped with a conveyor mechanism, a horizontal arrangement mechanism, and a stacking mechanism. The conveyor mechanism transports the boxes to the horizontal arrangement mechanism, where they are pushed into a row. The entire row of boxes is then sent to the stacking mechanism, where they are stacked sequentially onto the truck bed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a traveling loader packaging box conveying mechanism, which is used to convey the packaging box to a fixed position on the horizontal arrangement mechanism so that the automatic loader can perform the next horizontal arrangement operation, thereby solving the disadvantages of manual loading and improving loading efficiency.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A traveling loader packaging box conveying mechanism comprises a frame, a longitudinal belt conveyor fixedly connected to the frame, and two symmetrically arranged guide rods arranged above the belt conveyor, the two guide rods being arranged in a herringbone shape, the symmetry planes of the two guide rods being consistent with the movement direction of the belt conveyor, the ends of the two guide rods being away from each other being rotatably connected to the corresponding side of the belt conveyor, and the ends of the two guide rods being close to each other being close to the horizontal mechanism of the loader, and the frame being provided with an adjustment unit for driving the ends of the two guide rods close to the horizontal mechanism to move closer to or away from each other.

[0008] Furthermore, the adjustment unit includes a first plate arranged above or below the guide rod and two movable frames that can slide horizontally on the first plate, the first plate is connected to the frame, and the two movable frames are respectively rotatably connected to the corresponding guide rod at one end close to the horizontal mechanism, a horizontal screw is rotatably connected to the first plate, and nuts threadedly connected to the screw are fixedly connected to the two movable frames, and the threads of the two nuts mating with the screw have opposite rotation directions, and a first motor for driving the screw to rotate is fixedly connected to the first plate.

[0009] Furthermore, a second plate parallel to the first plate is provided above or below the first plate, the second plate is fixedly connected to the frame, the second plate and the first plate are slidably connected via a second linear guide module laterally arranged between the second plate and the first plate, a second motor is fixedly provided on the second plate, and the second motor drives the first plate to move laterally via a synchronous belt arranged between the first plate and the second plate.

[0010] Furthermore, the two movable frames are both C-shaped, and the two movable frames are symmetrically arranged with the belt conveyor as the center. The two movable frames are respectively buckled on both sides of the belt conveyor. The first flat plate is arranged below the movable frame, and the bottoms of the two movable frames are slidingly connected to the first flat plate. The upper ends of the two movable frames are respectively rotatably connected to the corresponding guide rods.

[0011] Furthermore, one end of each guide rod close to the horizontal mechanism is rotatably connected to a longitudinal straightening rod, and the adjustment unit is connected to the straightening rod.

[0012] Furthermore, a compensation plate is provided at one end of the two guide rods away from the horizontal mechanism, and both ends of each compensation plate are rotatably connected to the corresponding guide rod and the belt conveyor respectively.

[0013] Furthermore, a smooth and flexible sliding strip is fixedly provided on the inner side of the guide rod and the corresponding straightening rod.

[0015] The utility model comprises a frame, a belt conveyor, and two guide rods. Each guide rod is provided with a compensating plate connected to an adjustment unit. The adjustment unit comprises a lead screw, a nut, and two movable frames. The two movable frames are respectively connected to corresponding guide rods, and the lead screw drives the two movable frames to move synchronously in opposite directions. Under the action of the two guide rods, the packaging boxes are guided to the center of the belt conveyor, then transported from the belt conveyor to a transverse mechanism, where they are pushed into rows. Because the packaging boxes are delivered to the transverse mechanism at the same position from the belt conveyor, they do not interfere with the moving parts on the surface of the transverse mechanism, ensuring the normal operation of the transverse mechanism, improving loading efficiency, and preventing damage to the packaging boxes. A second plate is provided below the first plate of the adjustment unit. A synchronous belt between the second plate and the first plate drives the first plate to move laterally, thereby driving two straightening rods to move synchronously in the same horizontal direction.

[0024] For the convenience of description, in the following description, the direction consistent with the running direction of the belt conveyor 101 is referred to as "longitudinal", and the direction perpendicular to the running direction of the belt conveyor 101 in the horizontal plane is referred to as "transverse".

[0025] Example 1

[0026] like Figures 1 to 6 As shown, a traveling loader packaging box conveying mechanism includes a frame 6 formed by interconnected profiles, a longitudinal belt conveyor 101 fixedly connected to the frame 6, and two symmetrically arranged rigid guide rods 103 arranged above the belt conveyor 101. The two guide rods 103 are arranged in a herringbone shape, and the symmetry planes of the two guide rods 103 are consistent with the movement direction of the belt conveyor 101. The right ends of the two guide rods 103 are away from each other, and the right ends of the two guide rods 103 are rotatably connected to the front and rear sides of the belt conveyor 101 respectively. The left ends of the two guide rods 103 are close to the horizontal mechanism 2 of the loader. The frame 6 is provided with an adjustment unit for driving the two guide rods 103 to move closer to or away from one end of the horizontal mechanism 2.

[0027] The adjustment unit includes a rectangular first plate 105 arranged below the belt conveyor 101 and two movable frames 106 connected to the first plate 105 in a transverse sliding manner. The first plate 105 is connected to the frame 6, and the two movable frames 106 are respectively rotatably connected to the left ends of the corresponding guide rods 103. A transverse lead screw 111 is rotatably connected to the first plate 105, and the two movable frames 106 are fixedly connected with nuts 110 threadedly connected to the lead screw 111. The threads of the two nuts 110 and the lead screw 111 are in opposite directions. A first motor 112 is fixedly connected to the first plate 105, and the first motor 112 is a servo motor. The first motor 112 is connected to the lead screw 111 through a coupling.

[0028] Both movable frames 106 are C-shaped. The two movable frames 106 are symmetrically arranged with the belt conveyor 101 as the center. The two movable frames 106 are respectively buckled on both sides of the belt conveyor 101. The first flat plate 105 is arranged below the movable frame 106. The bottoms of the two movable frames 106 are slidingly connected to the first flat plate 105. The nut 110 is fixedly connected to the bottom of the corresponding movable frame 106. The upper ends of the two movable frames 106 are respectively rotatably connected to the corresponding guide rods 103.

[0029] Two groups of mutually parallel horizontal first linear guide modules 108 are provided between the two movable frames 106 and the first flat plate 105. The tracks of the first linear guide modules 108 are fixedly connected to the first flat plate 105. Each group of first linear guide modules 108 has two groups of sliders, and the two groups of sliders are respectively fixedly connected to the bottom of the corresponding movable frame 106.

[0030] A compensation piece 116 is provided at the right end of each of the two guide rods 103 , and both ends of each compensation piece 116 are rotatably connected to the corresponding guide rod 103 and the side of the belt conveyor 101 .

[0031] The working process of this utility model is:

[0032] First, the first motor 112 operates, driving the two movable frames 106 to move synchronously in opposite directions in the horizontal direction. This in turn drives the left ends of the two guide rods 103 to move in opposite directions, adjusting the distance between the left ends of the two guide rods 103 to correspond to the size of the packaging box. The packaging box is placed on the right end of the belt conveyor 101, which drives the packaging box from right to left. Under the action of the two guide rods 103, the packaging box is guided to the center of the belt conveyor 101. Then, it is transported from the middle of the left end of the belt conveyor 101 to the horizontal arrangement mechanism 2, where it is pushed into a row.

[0033] Since the packaging boxes are sent from the left end of the belt conveyor 101 to the same position of the horizontal mechanism 2, the packaging boxes will not interfere with the moving parts on the surface of the horizontal mechanism 2, thereby ensuring the normal operation of the horizontal mechanism 2.

[0034] Example 2

[0035] The difference between this embodiment and embodiment 1 is that:

[0036] The left end of each guide rod 103 is rotatably connected to a longitudinal righting rod 107. The upper portions of the two movable frames 106 are fixedly connected to the corresponding righting rod 107. A smooth, flexible slide 102 is fixedly mounted on the inner side of each guide rod 103 and the inner side of the corresponding righting rod 107. Each guide rod 103 and the corresponding righting rod 107 are connected to the same slide 102. Slide 102 can be made of plastic or rubber.

[0037] When the packaging box moves to the left, it passes between the two straightening rods 107, thereby straightening the packaging box and making it easier for the horizontal arrangement mechanism 2 to push the packaging boxes into rows.

[0038] Example 3

[0039] The difference between this embodiment and embodiment 2 is that:

[0040] A second plate 104 is provided below the first plate 105 and is parallel thereto. The second plate 104 is fixedly connected to the frame 6. Two second linear guide modules 109 are provided between the second plate 104 and the first plate 105, and are parallel to each other. The tracks of the second linear guide modules 109 are fixedly connected to the second plate 104, and the sliders of the second linear guide modules 109 are fixedly connected to the first plate 105. The second plate 104 and the first plate 105 are slidably connected via the second linear guide modules 109. A second motor 114 is fixedly provided on the second plate 104. A driving synchronous pulley is fixedly connected to the output shaft of the second motor 114. A driven synchronous pulley is rotatably connected to the second plate 104. A synchronous belt 115 is wound around the driving and driven synchronous pulleys. A connecting plate 113 is fixedly connected to the synchronous belt 115, and the connecting plate 113 is fixedly connected to the first plate 105. When the second motor 114 rotates, the first plate 105 is driven to move laterally via the synchronous belt 115.

[0041] When the first plate 105 moves laterally, it drives the two straightening rods 107 to move synchronously in the same direction laterally. The horizontal position of the opening between the two straightening rods 107 is adjusted according to the different specifications of the packaging boxes, so that the packaging boxes will not interfere with the moving parts on the surface of the horizontal mechanism 2 after entering the horizontal mechanism 2.
