TECHNICAL FIELD
[0001] The utility model relates to a block packaging assembly line, in particular to a block packaging assembly line. BACKGROUND
[0002] With the progress of technology and the enhancement of environmental awareness, in recent years, aerated concrete bricks (referred to as blocks) gradually replace traditional red bricks or green bricks and become the preferred material in many large civil engineering projects. After the blocks are cut into pieces, a block pile is formed, and the block pile needs to be sent to a bundling station to bundle the blocks by a bundling machine. The block pile is placed on a tray, and when it is bundled, a forklift lifts the tray carrying the blocks (the tray has a space for the fork of the forklift to enter), and moves the blocks to the truck. Obviously, this block handling method must be attached to a tray, and a tray is needed for each block handling, which will waste many trays and increase the cost for the manufacturer. In order to solve this problem, the applicant previously applied for a utility model patent (publication number CN217125231U) named "trayless packaging system". The trayless packaging system includes a block transfer rotary lifting device and a tray circulating conveying device along the conveying direction of the tray circulating conveying device, which is provided with a block clamping manipulator, a bundling machine and a block rotary lifting device in sequence. The tray circulating conveying device is composed of two horizontal conveying mechanisms and two lifting conveying mechanisms. The two horizontal conveying mechanisms are located between the two lifting conveying mechanisms, and the lifting conveying mechanisms can be connected with the two horizontal conveying mechanisms. The block clamping manipulator includes two clamping hands for clamping the blocks. Although this trayless packaging system can realize trayless bundling and packaging, the two rows of blocks clamped out from the lower part of the block clamping manipulator need to be stacked manually, which is very inconvenient.

[0018] like Figure 1 As shown, this dual-track block packaging production line includes a frame 1, a first conveying device 2, a second conveying device 3, a first rotating hoist 4, a second rotating hoist 5, and a block clamping hoist 6. The first conveying device 2 and the second conveying device 3 are parallel. The first conveying device 2 is used to transport the block stack to be packaged; the second conveying device 3 is used to place and stack the blocks taken from the block stack; the first rotating hoist 4 is used to clamp, rotate, and lower the block stack except for the top part of the bottom layer (e.g., ...). Figure 6 Step A in the process); the second rotating lifting device 5 is used to clamp the top part of the block stack except for the bottom two layers (e.g., Figure 6 (Step B in the text), then move to one side (while rotating the block), and wait for the block clamping lifting device 6 to clamp away two rows of blocks (as in...). Figure 6 (Step C in the text), then place the block down (e.g.) Figure 6(Step D in the process) In this way, the block pile that originally did not have two holes becomes a block pile with two holes. After the block pile is packed (tied with straps), the two forks of the forklift can be inserted into the two holes to transport the block pile away. The block clamping and lifting device 6 is used to stack the two rows of blocks that have been clamped away on the second conveying device 3 to form a block pile with two holes. The second conveying device 3 transports the stacked block pile to the corresponding position of the first rotating lifting device 4. The first rotating lifting device 4 then lifts the block pile onto the first conveying device 2, and the first conveying device 2 transports the block pile to the packaging station for packaging.
[0019] To achieve the above functions, such as Figure 1 As shown, a first guide rail 11 is provided on the frame 1, spanning above the first conveying device 2 and the second conveying device 3. A first trolley 7 is provided on the first guide rail 11, and the first trolley 7 is connected to a first power source that drives the first trolley 7. A first rotating hoist 4 is mounted on the first trolley 7. Driven by the first power source, the first trolley 7 can move back and forth above the first conveying device 2 and the second conveying device 3. Figure 1 As shown, a second guide rail 12 is provided on the frame 1, which spans above the first conveying device 2 and the second conveying device 3. A second trolley 8 is provided on the second guide rail 12, and the second trolley 8 is connected to a second power source that drives the second trolley 8. The second rotating hoist 5 and the block clamping hoist 6 are both installed on the second trolley 8. Driven by the second power source, the second trolley 8 moves left and right synchronously with the second rotating hoist 5 and the block clamping hoist 6, so that the block clamping hoist 6 can move back and forth above the first conveying device 2 and above the second conveying device 3. Since the second rotating hoist 5 and the block clamping hoist 6 move synchronously, the second rotating hoist 5 needs to work above the second conveying device 3, while the block clamping hoist 6 needs to work above the first conveying device 2 and the second conveying device 3. Therefore, the center distance between the second rotating hoist 5 and the block clamping hoist 6 needs to be equal to the center distance between the first conveying device 2 and the second conveying device 3. In other words, the distance from the center point of the first conveying device 2 to the center point of the second conveying device 3 is equal to the distance between the center point of the second rotating hoist 5 and the center point of the block clamping hoist 6.
[0020] The working principle of this double-track block packaging production line is as follows: The block stack is lifted by the first rotating hoist 4 or other hoisting device and placed on the first conveyor device 2 (the first conveyor device 2 is existing technology and includes a chain and sprockets). The first rotating hoist 4 clamps the block stack on the first conveyor device 2, except for the top part of the bottom layer, rotates it 90°, and then lowers it (e.g., ...). Figure 6A step) so that the lowermost row of blocks and the upper block stack form a vertical and horizontal arrangement, and then the first conveying device 2 continues to convey the block stack to the position of the second rotary hoist 5, and the second rotary hoist 5 lifts the upper part of the block stack except the lowermost two layers (as shown in Figure 6 B step), and then the second trolley 8 moves right with the second rotary hoist 5 and the block clamping hoist 6 synchronously (the second rotary hoist 5 rotates while moving, improving efficiency), so that the block clamping hoist 6 is above the first conveying device 2, and the block clamping hoist 6 clamps the two rows of blocks (as shown in Figure 6 C step), and then the second trolley 8 moves left with the second rotary hoist 5 and the block clamping hoist 6 synchronously, and the second rotary hoist 5 is above the first conveying device 2, and places the blocks on the lower two layers (as shown in Figure 6 D step), so that the block stack without two holes becomes a block stack with two holes, and after the block stack is packed (by a binding belt), the block clamping hoist 6 stacks the two rows of blocks on the second conveying device 3, and also stacks them into a block stack with two holes, and the second conveying device 3 conveys the stacked block stack to the position corresponding to the first rotary hoist 4, and the first rotary hoist 4 hoists the block stack on the second conveying device 3 to the first conveying device 2, and the first conveying device 2 conveys the block stack to the packing position for packing. Through the double-block packing line with such a structure, not only can it realize full automation and trayless binding and packing, but also, the first rotary hoist 4 rotates once, the second rotary hoist 5 rotates once, and in the process of rotation of the second rotary hoist 5, the block clamping hoist 6 clamps two rows of blocks, that is, the three hoists only do one work, and the second rotary hoist 5 and the block clamping hoist 6 can also complete the application action (such as rotation) in the process of horizontal movement, so that the packing efficiency can be significantly improved. In addition, since only one power source drives the synchronous movement of the second rotary hoist 5 and the block clamping hoist 6, the manufacturing cost is low. Moreover, through such a structural layout, the entire packing line can be minimized.
[0021] As Figure 2As shown, the block clamping hoist 6 comprises a clamping lifting frame 60, a clamping support 61 and two sets of clamping hands 62, the two sets of clamping hands 62 are installed on the clamping support 61, the clamping support 61 is rotatably installed on the clamping lifting frame 60 (driven by a rotating power source), and the clamping lifting frame 60 is liftably installed on the second trolley 8 (driven by a lifting power source); each set of clamping hands 62 is slidably arranged on the clamping support 61 through a clamping hand sliding seat 64, and the two sets of clamping hands 62 can be relatively moved by being driven by a clamping hand power source. When the block clamping hoist 6 comes above the first conveying device 2, the lifting power source drives the clamping lifting frame 60 to descend, and the left and right two sets of clamping hands 62 clamp and lift the left and right two rows of blocks respectively; when the block clamping hoist 6 comes above the second conveying device 3, the left and right two sets of clamping hands 62 put down the two rows of blocks; and the left and right two sets of clamping hands 62 can be relatively close to each other by being driven by the clamping hand power source, so that the blocks can be arranged on the horizontal layer, for example, Figure 6 As shown, the blocks are arranged into six rows on the horizontal layer, and the block clamping hoist 6 has a rotating function, so that the blocks can be arranged into a staggered arrangement in the vertical direction, and two insertion holes are left without blocks, so that the block clamping hoist 6 can arrange a block pile with two holes.
[0022] As shown, Figure 3 Each set of clamping hands 62 comprises a front clamping plate 620 and a rear clamping plate 621, the clamping hand sliding seat 64 is provided with a clamping hand guide rail 65, the front clamping plate 620 and the rear clamping plate 621 are slidably arranged on the clamping hand guide rail 65, and the front clamping plate 620 and the rear clamping plate 621 can be relatively moved by being driven by a clamping power source. By driving the clamping power source, the front clamping plate 620 and the rear clamping plate 621 are relatively moved, so that the front clamping plate 620 and the rear clamping plate 621 can clamp a row of blocks.
[0023] Due to the existence of errors, after the block clamping hoist 6 puts down the blocks, the blocks cannot reach a high-precision seamless state on the horizontal layer, and there will still be gaps between adjacent blocks; in order to solve this problem, as shown, Figure 3 A left and right set of layer clamping hands 63 is installed on the clamping support 61, the layer clamping hand 63 comprises a layer clamping plate 630 and a layer clamping arm 631, the layer clamping arm 631 is hinged to the clamping support 61, the layer clamping plate 630 is connected to the lower end of the layer clamping arm 631, and the layer clamping arm 631 is in transmission connection with a layer power source for driving the layer clamping arm 631 to rotate. When a layer of blocks is arranged, the layer power source drives the left and right two sets of layer clamping hands 63 to relatively move, clamps the layer of blocks, and eliminates the gaps between the blocks, so as to meet the block packaging requirements.
[0024] As shown, Figure 4As shown, the first rotating hoist 4 comprises a first lifting frame 40, a first support 41, and two first clamping plates 42, the two first clamping plates 42 are installed on the first support 41, the first support 41 is rotatably installed on the first lifting frame 40 (driven by a rotating power source), and the first lifting frame 40 is liftably installed on the first crab 7 (driven by a lifting power source); each first clamping plate 42 is slidably arranged on the first support 41 through a first sliding seat, and the two first clamping plates 42 can be relatively moved by being driven by a first clamping plate power source 43. When the block stack without the jack is stacked on the first conveying device 2, the first clamping plate power source 43 drives the two first clamping plates 42 to clamp the upper part of the block stack except the lowermost layer, rotate and put down; when the second conveying device 3 is stacked into a block stack, the first rotating hoist 4 can also hoist and deliver the block stack to the first conveying device 2, and then into the packaging process.
[0025] The second rotating hoist 5 comprises a second lifting frame 50, a second support 51, and two second clamping plates 52, the two second clamping plates 52 are installed on the second support 51, the second support 51 is rotatably installed on the second lifting frame 50 (driven by a rotating power source), and the second lifting frame 50 is liftably installed on the second crab 8 (driven by a lifting power source); each second clamping plate 52 is slidably arranged on the second support 51 through a second sliding seat, and the two second clamping plates 52 can be relatively moved by being driven by a second clamping plate power source 53. The structure of the second rotating hoist 5 is the same as that of the first rotating hoist 4, and will not be repeated here.
[0026] Finally, it is worth mentioning that all the power sources involved in the present application include but are not limited to air cylinders, oil cylinders, hydraulic cylinders, electric push rods and motors.
