[0002] As a basic building material, fired bricks are widely used in the construction industry. In the production process of fired bricks, the degree of mechanization and automation is high, while the number of mechanized production equipment related to finished bricks is relatively small. In the packaging process of finished bricks, the fired brick stacks need to be transferred layer by layer to the conveyor belt, and then transferred from the conveyor belt to the next process for re-stacking and packaging as required. In this process, a destacking device is required for destacking. The traditional destacking device consists of a rack and a brick clamp. The brick clamp is assembled on the rack. During destacking, the brick clamp clamps a layer of bricks on the brick stack, and then the rack drives the brick clamp to move to the conveyor belt to release the bricks. After that, the rack drives the brick clamp back to the brick stack to clamp the next layer of bricks. This can be repeated for continuous destacking. Although this destacking device can replace manual destacking, the overall destacking efficiency is low and it is difficult to meet the needs of large-scale destacking. Utility Model Content

DETAILED DESCRIPTION

[0025] The utility model will be further described below in conjunction with the accompanying drawings.

[0026] Reference Figure 1-Figure 6 As shown, the truss type depalletizing device of this embodiment includes a truss 1, a first rotation drive mechanism 2, a rotating frame 3, a clamping mechanism 4 and a lifting drive mechanism 5.

[0027] In this embodiment, the truss 1 is supported by two side frames distributed on the left and right. The truss 1 is gate-shaped as a whole. The truss 1 of this shape can leave space directly below so that a conveyor belt and a depalletizing device can be placed directly below.

[0028] In this embodiment, the first rotary drive mechanism 2 is arranged on the truss 1, and the rotating frame 3 is connected to the output end of the first rotary drive mechanism 2, and the first rotary drive mechanism 2 is used to drive the rotating frame 3 to rotate horizontally. Specifically, in this embodiment, the first rotary drive mechanism 2 includes a first mounting frame 21, a first driven shaft and a first driver 23, the first mounting frame 21 is fixedly connected to the truss 1, one end of the first driven shaft is rotatably connected to the first mounting frame 21 and the other end is fixedly connected to the rotating frame 3. A large gear is fixedly connected to the side of the first driven shaft, and the first driver 23 is used to drive the large gear to rotate. In this embodiment, the first driver 23 includes a first reducer and a first motor, the first reducer is fixedly connected to the first mounting frame 21, and its output shaft is fixedly connected to a small gear for rotatably meshing with the large gear. The first motor is fixedly connected to the first reducer and its output end is transmission-connected to the output end of the first reducer, so that when the first motor is working, the first driven shaft can be driven to rotate, and then the rotating frame 3 is driven to rotate, so that the clamping mechanism 4 can switch positions.

[0029] In this embodiment, the number of the clamping mechanisms 4 is 4, and the 4 clamping mechanisms 4 are arranged opposite to each other in pairs, and each pair of opposite pairs is a group. The spacing between the two clamping mechanisms 4 of the two groups of clamping mechanisms 4 is equal, and each group of clamping mechanisms 4 is distributed in a circular array around the rotation axis of the rotating frame 3, specifically in a cross-shaped distribution. In this embodiment, the clamping mechanism 4 includes a second rotary drive mechanism 41 arranged on the rotating frame 3 and a brick clamp 42 connected to the second rotary drive mechanism 41 in a transmission manner. The second rotary drive mechanism 41 is used to drive the brick clamp 42 to rotate horizontally, and the brick clamp 42 is used to clamp the bricks on the brick stack for unloading. The brick clamp 42 can specifically be a pneumatic or hydraulically driven clamp. In this embodiment, the second rotary drive mechanism 41 includes a second driven shaft, a second motor and a second reducer. The second driven shaft longitudinally penetrates the rotating frame 3 and is rotationally connected thereto. The second reducer is fixedly connected to the rotating frame 3, and its output end is transmission-connected to the second driven shaft. The second motor is fixedly connected to the second reducer, and the output end of the second motor is transmission-connected to the input end of the second reducer. When the second motor is working, it can drive the brick clamp 42 to rotate horizontally through the second reducer, so that the position and direction of the clamped brick can be changed.

[0030] In this embodiment, the lifting drive mechanism 5 includes a second mounting frame 51, a sliding member 52, a lifting chain 53 and a third driver 54. The second mounting frame 51 is fixedly connected to the middle part of the upper side of the truss 1. The first rotary drive mechanism 2 is longitudinally slidably connected to the second mounting frame 51 through the sliding member 52, so that the first rotary drive mechanism 2 can only slide up and down relative to the mounting frame 51. It is worth mentioning that there are four sliding members 52 in this embodiment, and the four sliding members 52 are evenly distributed on the second mounting frame 51, specifically in a rectangular distribution, so that the stability of the first rotary drive mechanism 2 when sliding up and down can be improved. In this embodiment, the sliding member 52 specifically includes a cylindrical sliding rod and a cylindrical fixed cylinder. The second mounting frame 51 is provided with a sliding hole that penetrates longitudinally, and the sliding rod penetrates the sliding hole to form a longitudinal sliding connection. The number of fixed cylinders of each sliding member 52 is two, and the two fixed cylinders are respectively fixed to the upper and lower ends of the second mounting frame 51, and are sleeved on the outer side of the sliding rod, so as to further stabilize the sliding direction of the sliding rod.

[0031] In this embodiment, the third driver 54 includes a third motor, a third reducer 541, a first gear 542 and a counterweight 543. The third reducer 541 is fixedly connected to the truss 1, the output end of the third motor is drivingly connected to the input end of the third reducer 541, the first gear 542 is fixedly connected to the output shaft of the third reducer 541, the counterweight 543 is longitudinally slidably connected to the side frame of the truss 1, and the end of the lifting chain 53 away from the first rotary drive mechanism 2 is fixedly connected to the counterweight 543. One end of the lifting chain 53 is fixedly connected to the first rotary drive mechanism 2 and the other end is fixedly connected to the counterweight 543. In addition, the lifting chain 53 is also drivingly assembled with the first gear 542, that is, meshingly assembled.

[0032] In a natural state, the counterweight 543 and the first rotary drive mechanism 2 will fall under their own gravity to tighten the lifting chain 53, so that when the third motor is working, the first gear 542 can be driven to rotate, and the first gear 542 can drive the lifting chain 53 to be retracted and released according to the rotation direction, so that the first rotary drive mechanism 2 can be driven to move up and down, and then the clamping mechanism 4 can be driven to move up and down. Counterweighting by the counterweight 543 can reduce the power burden of the third driver 54 to a certain extent, and can also extend the service life of the third driver 54 while reducing power consumption.

[0033] It is worth mentioning that the lifting drive mechanism 5 also includes a second gear 55, which is rotatably connected to the second mounting frame 51, and the lifting chain 53 is transmission-assembled, that is, meshing-assembled with the second gear 55. Such an arrangement enables the lifting chain 53 to vertically pull and release the first rotary drive mechanism 2, so that the lifting chain 53 drives the first rotary drive mechanism 2 to rise and fall smoothly.

[0034] In this embodiment, there are four lifting chains 53, and the fixed positions of the four lifting chains 53 and the second mounting frame 51 are evenly distributed on the second mounting frame 51, specifically in a rectangular distribution. Each lifting chain 53 is configured with a first gear 542 and a second gear 55. The four first gears 542 are all fixedly connected to the output shaft of the third reducer 541, specifically, the output shaft of the third reducer 541 passes through the opposite ends of the third reducer 541, and the four first gears 542 are grouped in pairs, and the two groups of first gears 542 are respectively arranged at the opposite ends of the output shaft. The four second gears 55 are all rotatably connected to the second mounting frame 51 through a rotating seat, and are distributed in a rectangular shape, so that the first rotary drive mechanism 2 can be evenly stressed when being pulled, further improving the lifting stability of the first rotary drive mechanism 2.

[0035] This embodiment can be arranged in the following manner when actually used. The truss 1 can be directly placed on the ground, and a stacking device can be arranged on the left and right sides of the truss 1. The brick-feeding device is a device for lifting the stacked bricks layer by layer. When the truss-type stacking device is unloading, the stacking devices on both sides can deliver bricks at the same time. The center of the truss 1 can be used to arrange a conveyor belt facing forward and backward. The conveyor belt is used to receive the bricks put down by the brick clamp 42 and send the bricks forward or backward.

[0036] In the initial state, the four brick clamps 42 are all in an open state. The two brick clamps 42 opposite to each other on the left and right (hereinafter referred to as the first pair of clamps) are opposite to the two piles of bricks on the left and right sides, that is, they are located directly above the brick piles of the two stacking devices, and the two brick clamps 42 opposite to each other front and back (hereinafter referred to as the second pair of clamps) will be located directly above the conveyor belt. During unloading, the lifting drive mechanism 5 drives the rotating frame 3 to drive each brick clamp 42 to descend at the same time. When the first pair of clamps descends to a height that can clamp bricks, the first pair of clamps is controlled to clamp a layer of bricks. Then the lifting drive mechanism 5 controls the rotating frame 3 to rise, so that the clamped bricks are separated from the stacking device. Then the first rotating drive mechanism 2 is controlled to drive the rotating frame 3 to rotate horizontally 90 degrees (at the same time, the stacking device should be controlled to drive the brick stack to increase the height to prepare for the next brick retrieval). After rotation, the first pair of clamps will be opposite to the conveyor belt, and the second pair of clamps will be opposite to the two stacks of bricks. At this time, the lifting drive mechanism 5 drives the rotating frame 3 to descend again. When the second pair of clamps descends to a height that can clamp bricks, the bricks clamped by the first pair of clamps will be close to the upper surface of the conveyor belt. At this time, the first pair of clamps can be controlled to release the bricks so that the bricks stop on the conveyor belt. At the same time, the second pair of clamps can be controlled to clamp a layer of bricks. Then the rotating frame 3 is controlled to rise and the above operations are repeated (after the brick clamps 42 release the bricks on the conveyor belt, the brick clamps 42 can control the conveyor belt to work during the rising process to send the bricks away to leave space for the next brick placement. After leaving space for placement, the conveyor belt can be controlled to stop working and wait for the brick clamps 42 to place the bricks). This cycle can be used for continuous unloading.

[0037] To sum up, the utility model discloses a truss type stacking device, which can realize brick taking and brick placing on both sides at the same time, and has twice the brick unloading efficiency compared with the prior art. In addition, while one pair of clamps is taking bricks, the other pair of clamps can be unloaded and rotated at the same time, which can increase the brick unloading efficiency by four times. The brick unloading efficiency is greatly improved and can meet the needs of large-scale brick unloading. The truss design also facilitates the layout of components such as conveyor belts and stacking devices to efficiently utilize space.
