Abstract
Description
Technical Field
[0001] The utility model relates to the field of depalletizing equipment, in particular to a frame holding machine for depalletizing. Background Art
[0002] The existing method of unstacking bricks mainly relies on manual or traditional equipment to hold bricks layer by layer, which has the following defects: (1) When the brick stack is relatively loose, it must be gathered first and then held. During the gathering process, the contact surface between the first and second layers of bricks is uneven, causing the second layer of bricks to trip over the first layer of bricks when the first layer of bricks is gathered, interrupting the brick holding process. (2) When the brick stacks are stacked layer by layer, the two adjacent layers of bricks may occasionally stick to each other. When the upper layer of bricks is clamped and lifted, the lower layer of bricks will be lifted up, destroying the stacking position of the lower layer of bricks, resulting in the lower layer of bricks not being clamped normally. (3) Because the clamps of the traditional single-layer clamping device are all set on the same plane, when the bricks to be unstacking are placed on an inclined surface, the traditional clamping device still performs the clamping work according to the horizontal working surface, which is prone to the risk of loose layers or even loose stacks.
[0003] The purpose of the utility model is to provide a frame holding device for dismantling stacks, which has automatic positioning of the working surface, can overcome the problem of uneven lower bricks and can stably hold bricks, and has a high degree of automation, so as to solve practical problems of civil engineering enterprises and make up for the technical defects of the prior art. Utility Model Content
[0004] The purpose of the utility model is to provide a frame-holding device for stacking with automatic positioning of the working surface, which can overcome the problem of uneven lower bricks and can stably hold bricks, and has a high degree of automation. The working mode of clamping first and then holding after height positioning and the coordinated movement of multiple cylinders can not only effectively avoid the risk of loose layers or stacks in the clamping and holding process, but also extend the service life of the equipment and expand the adaptability of the equipment.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A frame holding machine for depalletizing: the frame holding machine for depalletizing comprises a frame body which can rotate horizontally, and a clamping device and a frame holding device are arranged below the frame body;
[0007] The clamping device includes several groups of fixed rods A in the same horizontal plane, and connecting ears with hanging holes are provided on the side walls at both ends of each of the fixed rods A, and at least two L-shaped fixing blocks are provided on each fixed rod A, and the upper part of each L-shaped fixing block is connected to the fixed rod A, and the lower part is connected to the fixed rod B, and the fixed rod B is provided with several groups and is in the same horizontal plane, and the extension direction of each fixed rod A is 90° with the extension direction of each fixed rod B located therebelow, and the lower surface of each fixed rod B is provided with several groups of clamping block groups, and the top of the clamping block group is embedded in the slideway A provided at the lower part of the fixed rod B through its own slide rail A, and each of the clamping block groups includes two relatively arranged clamping blocks A, and the two are connected by a transverse cylinder A, and as the transverse cylinder A is opened and closed, the relatively arranged clamping blocks A move correspondingly on the slideway A, and the lower part of each group of relatively arranged clamping blocks A is provided with a first clamping module, and the first clamping module opens and closes the clamping blocks A for clamping as they are opened and closed;
[0008] The frame holding device includes a plurality of fixing rods C on the same horizontal plane, the fixing rods C are located below the plane where the fixing rods B are located, and are connected to the fixing rods B through a plurality of T-shaped fixing frames, both ends of each fixing rod C extend downward to be fixed to the sheet-shaped second clamping module, and each fixing rod C is provided with a plurality of clamping blocks B, the clamping blocks B near the two ends of the fixing rod C are arranged facing the second clamping module, and are connected and controlled by a transverse cylinder B to open and close, the clamping blocks B (307) located in the middle of the fixing rod C are arranged opposite to each other, and are connected and controlled by a transverse cylinder B to open and close, and the top of the clamping block B is embedded in the slideway B provided at the bottom of the fixing rod C through its own slide rail B;
[0009] Each T-shaped fixing frame includes a T-shaped component and a vertical cylinder A and a vertical cylinder B. The upper part of the T-shaped fixing frame is hung and fixed on the fixing rod A. The piston of the vertical cylinder A is fixedly connected to the fixing rod B, and the piston of the vertical cylinder B is fixedly connected to the fixing rod C.
[0010] Preferably, the frame body includes a frame-type fixing frame and plug-in fixing blocks arranged on the four corners of the fixing frame, each of the plug-in fixing blocks passes through a hanging hole on the corresponding connecting support ear, and a rotating module is arranged on the upper part of the fixing frame, and a bearing set that can rotate horizontally is arranged on the rotating module.
[0011] Preferably, several tightening modules are arranged at the lower part of the several groups of fixing rods B, each of the tightening modules comprises a transversely arranged cylinder with a rectangular cross section and two fixed connecting rods extending upward from the upper part of the cylinder, and the connecting rods are fixedly arranged on the side wall of the fixing rod B.
[0012] Preferably, the plug-in fixing block is inserted into the hanging hole of the connecting ear, and a limiting nut is provided at one end of the connecting ear.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The utility model makes the tightening block at the bottom of the frame clamping machine contact the outer wall surface of the top of the brick pile before formal operation. Through the movable connection between the connecting ear and the plug-in fixing block, the tightening block drives the entire frame clamping machine to adapt to the uneven brick pile, so as to achieve the effect of automatic positioning, so that the brick pile is not easy to be loose or the danger of loose stacking occurs during the clamping process.
[0015] 2. The utility model adopts a working mode of clamping first and then holding. When the equipment is working, the frame holding device will first clamp the second layer of the brick stack and then the clamping device will clamp the first layer. The displacement difference between the vertical cylinder A and the vertical cylinder B separates the first and second layers of the brick stack, which makes it less likely to cause the two layers to stick together or the brick layers to be uneven, causing the bricks to fall apart when being lifted.
[0016] 3. In the utility model, since the clamping device and the frame holding device can be controlled separately by their different cylinders, the working sequence can be fine-tuned according to actual work needs to adapt to different types of brick stacks. In addition, the frame holding machine adopts multi-cylinder coordinated movement, which not only has uniform force but also facilitates the replacement of wearing parts, thereby extending the service life of the equipment and expanding the adaptability of the equipment.
[0017] In summary, the utility model is a frame holding machine for depalletizing, which adopts a working mode of clamping first and then holding after height positioning. Compared with traditional manual depalletizing or single-layer depalletizing machines, it can effectively avoid the risk of loose layers or loose stacks during the clamping and holding process. Under the frame holding device, the relative movement of the vertical cylinder A and the vertical cylinder B can solve the risk of loose layers when lifting due to adhesion between the two layers or uneven brick layers. In addition, the device adopts multi-cylinder coordinated movement, which not only ensures uniform force but also facilitates the replacement of wearing parts, thereby extending the service life of the equipment and expanding the adaptability of the equipment.
