Description

Technical Field

[0001] The utility model belongs to the technical field of stacking devices, and in particular relates to a stacking device for bricks. Background Art

[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, it is necessary to transfer the fired bricks on the front conveyor belt to the rear conveyor belt for stacking layer by layer to form a brick stack for packaging. The mechanical equipment used in this link is a stacking device. The existing stacking device consists of a rack and a brick clamp. The brick clamp is assembled on the rack. When stacking, the brick clamp first clamps a layer of bricks on the front conveyor belt, and then the rack drives the brick clamp to move to the rear conveyor belt to release the bricks. After that, the rack drives the brick clamp back to the front conveyor belt to continue clamping the bricks, and then the rack drives the brick clamp to move to the rear conveyor belt to stack the bricks on the previous layer of bricks. In this cycle, a brick stack can be stacked. Although this type of stacking device can replace manual unloading, the overall stacking efficiency is low and it is difficult to meet the needs of large-scale unloading. Utility Model Content

DETAILED DESCRIPTION

[0021] The utility model will be further described below in conjunction with the accompanying drawings.

[0022] Example 1

[0023] Reference Figure 1-Figure 2 As shown, a brick stacking device of this embodiment includes a base 1, a clamping mechanism 2, a first rotation drive assembly 3, a rotating frame 4 and a lifting drive assembly 5. The base 1 is used to connect to the ground, and the clamping mechanism 2 is used to clamp bricks. In this embodiment, there are two clamping mechanisms 2 and two lifting drive assemblies 5, and the two clamping mechanisms 2 are respectively connected to the rotating frame 4 through two lifting drive assemblies 5. The two clamping mechanisms 2 are distributed on both sides of the rotation axis of the rotating frame 4, specifically distributed at 180 degrees.

[0024] In this embodiment, the first rotation drive assembly 3 is arranged on the base 1 and its output end is transmission-connected with the rotating frame 4. The first rotation drive assembly 3 is used to drive the rotating frame 4 to rotate horizontally. Specifically, the first rotation drive assembly 3 includes a first driven gear, a first driving gear and a first driver 303. The first driven gear is rotationally connected with the base 1 and fixedly connected with the rotating frame 4. The first driver 303 is arranged on the base 1 and its output end is transmission-connected with the first driving gear. The first driving gear is meshed with the first driven gear. The first driver 303 in this embodiment is a motor. When the first driver 303 drives the first driving gear to rotate, the first driving gear can drive the first driven gear to rotate. Since the number of teeth of the first driving gear is less than the number of teeth of the first driven gear, the power output by the first driver 303 can be decelerated and torque-increased, so that the rotating frame 4 can be better driven to rotate. When the rotating frame 4 rotates, it can drive the two clamping mechanisms 2 to rotate. If the first driver 303 drives the rotating frame 4 to rotate horizontally by 180 degrees, the two clamping mechanisms 2 will be swapped with each other.

[0025] In this embodiment, the rotating frame 4 has an intermediate column and two rectangular frames. The lower end of the intermediate column is fixedly connected to the first driven gear. The rectangular frame is a vertical through structure. The two rectangular frames are fixedly connected to the upper end of the intermediate column relative to one end, and the two rectangular frames are distributed at 180 degrees.

[0026] In this embodiment, the clamping mechanism 2 is connected to the rotating frame 4 through the lifting drive assembly 5, and the lifting drive assembly 5 is used to drive the clamping mechanism 2 to move up and down. Specifically, the lifting drive assembly 5 includes a frame 31, a lifting rod 32, a lifting transmission assembly 33 and a second driver 34. The frame 31 is fixed to the rectangular frame, and the lifting rod 32 is longitudinally slidably connected to the frame 31. The lifting transmission assembly 33 is transmission-connected between the lifting rod 32 and the second driver 34, and the second driver 34 is used to cooperate with the lifting transmission assembly 33 to drive the lifting rod 32 to move up and down.

[0027] In this embodiment, the lifting transmission assembly 33 specifically includes a transmission chain 331, a first auxiliary gear 332, a second auxiliary gear 333 and a second driving gear 334. The upper and lower ends of the transmission chain 331 are respectively fixed to the upper and lower ends of the lifting rod 32. The first auxiliary gear 332 and the second auxiliary gear 333 are both rotatably connected to the frame 31. The second driving gear 334 is rotatably connected to the frame 31 and is transmission-connected to the output end of the second driver 34. The first auxiliary gear 332 and the second auxiliary gear 333 are both located between the second driving gear 334 and the lifting rod 32. The transmission chain 331 is meshed with the lower side of the first auxiliary gear 332, the rear side of the second driving gear 334 and the upper side of the second auxiliary gear 333 in sequence, and the transmission chain 331 is in a taut state. When the second driver 34 drives the second driving gear 334 to rotate, the second driving gear 334 will drive the transmission chain 331 to move up and down, so that the upper and lower ends of the transmission chain 331 will drive the lifting rod 32 to slide up and down in the frame 31, and when the lifting rod 32 slides up and down, it will drive the clamping mechanism 2 at its lower end to move up and down. In this embodiment, the second driver 34 is composed of a reducer and a motor. The reducer is fixedly connected to the frame 31, and its output end is transmission-connected to the second driving gear 334. The motor is fixedly connected to the reducer, and its output end is transmission-connected to the input end of the reducer. When the motor is working, the power output by the motor can drive the second driving gear 334 to rotate after being decelerated and torque-increased by the reducer.

[0028] In this embodiment, the three sides of the lifting rod 32 without the transmission chain 331 are fixedly connected to the longitudinally arranged limit rods 321, and the limit rods 321 are specifically slide rails. The positions corresponding to the three limit rods 321 on the frame 31 are all provided with assembly slots, and each assembly slot is detachably connected with a slide seat 322 longitudinally slidably connected to the corresponding limit rod 321. Such an arrangement can enhance the connection strength between the lifting rod 32 and the frame 31 and improve the sliding stability.

[0029] In the present embodiment, a second rotating drive assembly 6 is further provided between the clamping mechanism 2 and the lifting drive assembly 5, and the second rotating drive assembly 6 is used to drive the clamping mechanism 2 to rotate horizontally. Specifically, the second rotating drive assembly 6 includes a housing 61, a third driving gear, a second driven gear and a third driver 64, the housing 61 is fixedly connected to the lower end of the lifting rod 32, the second driven gear is rotationally connected to the housing 61 and is fixedly connected to the clamping mechanism 2, and the third driving gear is transmission-connected to the output end of the third driver 64 and meshes with the second driven gear. In the present embodiment, the number of teeth of the second driven gear is greater than the number of teeth of the third driving gear, and such a setting is also for amplifying the torque. When the third driver 64 drives the third driving gear to rotate, the third driving gear will drive the second driven gear to rotate, so that the second driven gear can drive the clamping mechanism 2 to rotate horizontally. In the present embodiment, the structure of the third driver 64 can refer to the structure of the second driver 34, which will not be repeated here.

[0030] After such arrangement, when it is necessary to place the bricks clamped by the clamping mechanism 2 at different angles, this can be achieved by controlling the clamping mechanism 2 to rotate horizontally to meet the placement requirements at different angles.

[0031] When the stacking device of this embodiment is used, one clamping mechanism 2 should be aligned with the brick feeding belt, and the other clamping mechanism 2 should be aligned with the stacking conveyor belt. When stacking, the brick feeding belt first delivers bricks to wait for the clamping mechanism 2 to pick them up in advance. When clamping, the lifting drive assembly 5 controls the clamping mechanism 2 (hereinafter referred to as the first clamping mechanism 2, and the other clamping mechanism 2 is the second clamping mechanism 2) to descend in height. When it descends to a height that can clamp bricks, the first clamping mechanism 2 is controlled to clamp the bricks (after which the brick feeding belt should be controlled to deliver bricks to prepare for the next brick retrieval). Then the first rotating drive assembly 3 is controlled to drive the rotating frame 4 to rotate 180 degrees, so that the first clamping mechanism 2 is aligned with the stacking conveyor belt. In this state, the second clamping mechanism 2 will be aligned with the brick feeding belt at the same time. At this time, on the one hand, the first clamping mechanism 2 can be controlled to put bricks on the stacking conveyor belt for stacking, and on the other hand, the second clamping mechanism 2 can be controlled to clamp the bricks on the brick feeding belt for taking bricks. In this cycle, the stacking operation can be completed. It can be seen that when one of the clamping mechanisms 2 of the stacking device places bricks for stacking, the other clamping mechanism 2 can simultaneously perform the brick-taking operation. When the clamping mechanism 2 has stacked the bricks, the other clamping mechanism 2 can immediately stack them again, thereby reducing the waiting time for taking bricks, and then shortening the stacking time, so as to improve the stacking efficiency to meet the large-scale production needs.

[0032] It is worth mentioning that the two clamping mechanisms 2 are arranged relative to each other to balance the gravity on both sides of the first rotary drive assembly 3, which can improve the rotation balance of the rotary frame 4 to a certain extent, thereby increasing the service life of the entire palletizing device.

[0033] Example 2

[0034] The difference between this embodiment and embodiment 1 is that there are three clamping mechanisms 2, and there are three corresponding lifting drive components 5 and rectangular frames. The three rectangular frames are distributed in an equilateral triangle, and correspondingly, the three lifting drive components 5 are also distributed in an equilateral triangle, so that the three clamping mechanisms 2 are distributed in an equilateral triangle around the rotation axis of the rotating frame 4.

[0035] When using the layout of this embodiment, two clamping mechanisms 2 can correspond to two brick feeding conveyor belts respectively, and another clamping mechanism 2 can correspond to the stacking conveyor belt, thereby forming a two-to-one stacking layout, which can further reduce the waiting time for taking bricks and further improve the stacking efficiency.

[0036] In summary, the utility model discloses a brick stacking device, which can be used to take bricks by one or more clamping mechanisms 2 while one clamping mechanism 2 is stacking bricks. After one clamping mechanism 2 stacks bricks, the subsequent clamping mechanism 2 can immediately stack bricks again, and the previous clamping mechanism 2 will take bricks synchronously. Such cyclic stacking can reduce the waiting time for taking bricks, thereby shortening the stacking time, thereby improving the stacking efficiency and meeting the large-scale production needs.
