Description

Technical Field

[0001] The invention relates to a plate stacking system and belongs to the technical field of plate processing. Background Art

[0002] Wood boards are common materials in the construction industry, furniture making, and decoration. The processing of boards involves the stacking of boards. There are two main types of board stacking: one is the boards after processing, which are generally stored in a stacking manner to save storage space; the other is the boards that need to be transported, which are also transported in a stacking manner to save transportation space and facilitate handling.

[0003] Wood itself contains a certain amount of moisture, so the moisture content of newly processed boards is relatively high. In order to ensure the quality of wood and wood products and extend their service life, measures must be taken to reduce the moisture in the wood (moisture content of wood) to an allowable range. To reduce the moisture content of wood, the temperature of the wood must be increased to evaporate the moisture in the wood and dissipate it out of the wood. Therefore, in the process of preparing for stacking of boards, several pads will be stacked parallel to the length of the boards between the layers of the board stack, perpendicular to the length of the boards, so that a drying channel is formed between the layers of the board stack to facilitate air flow, so that moisture quickly leaves the wood, accelerates the drying of the boards, and avoids the possibility of decay and mildew caused by the close storage of damp boards, which changes the performance of the boards, thereby affecting the quality and service life of the board products. When the dry boards are stacked and packaged for transportation, since the boards are already dry and in order to save the space and padding occupied by the board stacks, there is no need to place padding strips between the layers of the board stacks during transportation. The boards only need to be stacked into board stacks in sequence and then packaged for transportation. For board stacks that have padding strips between layers during storage, it is necessary to remove the padding strips between the layers before stacking the dry boards.

[0004] The stacking of plate stacks involves the stacking of plate stacks with padding strips and the stacking of plate stacks without padding strips, and also involves the removal of padding strips between plate layers. Currently, there is no equipment that can automatically stack these two types of plate stacks and remove the padding strips at the same time, so the stacking of plate stacks is generally done manually. Manual stacking of plates requires multiple workers to collaborate simultaneously, which is labor-intensive and inefficient.

[0005] Therefore, a plate stacking system is needed to reduce the workload of manually stacking plate stacks and improve the stacking efficiency of plate stacks. Summary of the invention

[0006] The present invention aims to solve the problem that there is no equipment in the prior art that can automatically stack plate stacks with padding strips and plate stacks without padding strips and can also remove padding strips between layers of plate stacks, and the plate stacks are mainly stacked manually, which has high work intensity and low efficiency. The present invention provides a plate stacking system that can automatically stack plate stacks and can stack padding strips or not stack padding strips and remove padding strips between layers of plate stacks as needed.

[0007] The technical solution of the present invention to solve the above technical problems is as follows:

[0008] A plate stacking system comprises a plate quantitative conveying device and a plate stacking device arranged behind the plate quantitative conveying device;

[0009] The plate quantitative conveying device comprises a conveying frame, a plurality of conveying chains arranged in parallel on the conveying frame, a pressing mechanism arranged on the conveying frame, and a discharging mechanism arranged behind the pressing mechanism, wherein the pressing mechanism comprises a pressing arm and a pressing arm driving mechanism, and the pressing arm driving mechanism can drive the pressing arm to rotate downward to separate the plates along the conveying direction; the discharging mechanism comprises a feeding arm and a feeding arm driving mechanism; the feeding arms are at least 2; the feeding arm driving mechanism can drive the feeding arm to flip upward and translate along the conveying direction to feed the plates into the plate stacking device;

[0010] The plate stacking device comprises a stacking frame, a lifting platform arranged on the stacking frame, and a lifting platform driving mechanism; the lifting platform driving mechanism can drive the lifting platform to move up and down on the stacking frame.

[0011] The beneficial effects of the present invention are:

[0012] 1. According to the required number of plates per layer of the plate stack, the pressing arm of the plate quantitative conveying device rotates downward to press the plates below it to separate the plates in the front and rear directions of the plate, the plates in front of the plate stop conveying, and the quantitative plates behind it continue to be conveyed backward, so as to realize the automatic quantitative transmission of the plates;

[0013] Second, the quantitative plates are transported to the plate stacking device for stacking through the feeding arm of the plate quantitative conveying device, thereby reducing the workload of manual handling;

[0014] 3. Automatically stacking the plates is achieved by automatically lifting and receiving the lifting platform of the plate stacking device and stacking the plates transported by the feeding arm.

[0015] On the basis of the above technical solution, in order to achieve the convenience of use and the stability of the equipment, the present invention can also make the following improvements to the above technical solution:

[0016] Furthermore, the pressing arm driving mechanism includes a pressing cylinder; the output end of the pressing cylinder is connected to the pressing arm; the pressing mechanism also includes at least two material guide plates arranged below the pressing arm, and the material guide plates are arranged between the conveying chains; the middle part of the upper end surface of the material guide plate is higher than the upper end surface of the conveying chain, and the two ends of the upper end surface of the material guide plate are respectively inclined downward to below the upper end surface of the conveying chain.

[0017] The beneficial effect of adopting the above-mentioned further technical scheme is that the pressing arm is driven by the pressing cylinder to rotate downward to press the plate below it; the friction between the plate and the conveying chain is reduced when the pressing arm presses the plate by setting a guide plate; when the plate is transported to the guide plate on the conveying chain, because the upper end surface of the guide plate is higher than the upper end surface of the conveying chain, the plate is higher than the conveying chain, and when the pressing arm rotates downward to press the plate, the plate is pressed on the guide plate and blocks the plate in front from being conveyed backward, thereby reducing the friction of the plate being directly pressed on the conveying chain, so that the rotation of the conveying chain is not affected, and the efficiency of the conveying chain in conveying a certain amount of plates at the rear is improved.

[0018] Furthermore, the feeding arm driving mechanism comprises a feeding platform, a flip cylinder (3.11) and a feeding platform driving mechanism; the feeding arm is a square plate, one side of the feeding arm is hingedly mounted on the feeding platform, and the feeding platform driving mechanism can drive the feeding platform to drive the feeding arm to translate along the conveying direction; a flip cylinder is provided on the feeding platform and at the front end of the feeding arm, and the output end of the flip cylinder is hingedly connected to the front end of the feeding arm and to the side that is not hinged to the feeding platform; the discharging mechanism also comprises a baffle plate, which is arranged at the rear end of the conveying frame, and at least two baffle plates are provided, the upper end surface of the baffle plate is higher than the upper end surface of the conveying chain, and the upper end surface of the baffle plate is lower than the upper end surface of the feeding arm after it is flipped upward.

[0019] The beneficial effect of adopting the above-mentioned further technical scheme is that the feeding arm is pushed to flip upward by the flipping cylinder, so that the upper end surface of the feeding arm is higher than the upper end surfaces of the conveying chain and the baffle plate, and the plate is pushed onto the feeding arm; the feeding arm is driven by the feeding platform to move backward to the lifting platform of the plate stacking device, and then the flipping cylinder drives the feeding arm to flip downward, and the feeding platform drives the feeding arm to move forward. The plate is blocked by the baffle plate and cannot move forward with the feeding arm, but is placed on the lifting platform, thereby realizing the automatic transportation of quantitative plates from the plate quantitative conveying device to the plate stacking device.

[0020] Furthermore, the plate quantitative conveying device also includes an intercepting mechanism arranged between the pressing mechanism and the discharging mechanism, and the intercepting mechanism includes an intercepting arm and an intercepting arm driving mechanism; the intercepting arm driving mechanism can drive the intercepting arm to rotate upward to intercept the plate on the conveying chain; the intercepting arm driving mechanism is an intercepting cylinder.

[0021] The beneficial effect of adopting the above further technical solution is that the intercepting arm intercepts the plate, causing the plate to slip on the conveying chain and stop moving backward, providing time for the pressing arm to rotate downward, facilitating the pressing mechanism to perform the pressing operation, and after the pressing mechanism presses the plate below it, the intercepting arm no longer intercepts the plate, and the plate between the pressing mechanism and the intercepting mechanism can continue to be conveyed backward. Since the distance between the intercepting mechanism and the pressing mechanism is fixed, the number of plates between the intercepting mechanism and the pressing mechanism is fixed, and the quantitative separation of the plates is better achieved.

[0022] Furthermore, it also includes an automatic plate feeding and sorting device arranged in front of the plate quantitative conveying device; the plate quantitative conveying device and the automatic plate feeding and sorting device are connected by a chain; the automatic plate feeding and sorting device includes:

[0023] Loading rack;

[0024] A conveying mechanism is arranged on the feeding frame, the conveying mechanism comprises a feeding chain and a first sprocket and a second sprocket for driving the feeding chain to rotate; the height of the first sprocket is higher than that of the second sprocket; the first sprocket is arranged at one end close to the quantitative conveying device for the plate material; the upper section of the feeding chain is arched;

[0025] A supporting member supporting the upper section of the feeding chain in an arched shape;

[0026] And a plurality of stop blocks are arranged on the feeding chain, and the spacing between adjacent stop blocks is greater than or equal to the width of the plate.

[0027] The beneficial effect of adopting the above-mentioned further technical scheme is that by setting the height of the first sprocket higher than that of the second sprocket, and arranging multiple stop blocks on the feeding chain, the conveying mechanism is tilted upward, and the stop blocks push the plates to be conveyed upward along with the feeding chain, thereby realizing automatic loading and conveying of the plates; by setting the upper section of the feeding chain to be arched, when the plates are conveyed upward, the plates that are not placed in parallel will leave the surface of the feeding chain during the conveying process due to the different contact angles of each part with the surface of the feeding chain, so that part of the plates will be higher than the height of the stop blocks, and thus fall down due to the loss of support of the stop blocks, and the fallen plates are pushed upward by the stop blocks again, and this cycle is repeated until the plates are conveyed in parallel, and the plates are automatically sorted in the process of conveying the plates upward so that the plates are parallel to each other, and there is no need to manually sort the plates that are not conveyed in parallel.

[0028] Furthermore, the support member includes an arc frame; the arc frame includes an inclined plate and an arched plate arranged on the inclined plate, and both ends of the arched plate are respectively fixed on the inclined plate; the shape of the arched plate is adapted to the arch of the upper section of the feeding chain.

[0029] The beneficial effect of adopting the above further technical solution is that the arc frame provides support for the feeding chain and keeps the upper section of the feeding chain in an arched shape, so that the feeding chain is conveyed more smoothly.

[0030] Furthermore, it also includes an automatic strip removal device for the interlayer pads of the plate material arranged in front of the automatic feeding and sorting device for the plate material; the automatic strip removal device for the interlayer pads of the plate material includes a strip removal rack, a turning mechanism arranged on the strip removal rack and a material dropping mechanism arranged at the rear of the turning mechanism; the turning mechanism includes a turning frame installed on the strip removal rack and a turning and strip removal driving mechanism; the turning frame includes a guide rail and a moving platform; the guide rail can be rotatably installed on the strip removal rack, and a slide groove is provided on the guide rail; the rear end of the moving platform can be movably installed on the slide groove; the turning and strip removal driving mechanism can drive The guide rail is driven to rotate on the strip drawing frame; the flipping strip drawing driving mechanism can also drive the mobile platform to translate on the guide rail; the mobile platform includes a plurality of parallel arms, and the rear ends of the parallel arms are movably installed on the slide groove; the blanking mechanism includes a bracket and a plurality of parallel plate conveying chains; the bracket is provided with an inclined guide plate; one end of the plate conveying chain is arranged below the guide plate, and the other end extends to the rear of the guide plate; a plurality of spacer blocks are arranged at intervals on the plate conveying chain; the spacer blocks on adjacent plate conveying chains correspond to each other one by one.

[0031] The beneficial effect of adopting the above-mentioned further technical scheme is that the function of automatically removing the padding strips from the stack of plates with padding strips can be realized through the automatic removal device of the padding strips between the plates, thereby reducing the workload of manual removal of the padding strips and improving work efficiency; the plates and the padding strips are separated by the flipping mechanism, and when the plates and the padding strips fall from the flipping mechanism, the plates and the padding strips are guided to slide down by the guide plate of the blanking mechanism, and the plates fall onto the plate conveying chain and are output through the plate conveying chain; the padding strips fall through the gaps between the plate conveying chains, thereby realizing the automatic separation of the padding strips from the plates and the automatic removal of the padding strips.

[0032] Furthermore, the flipping and drawing driving mechanism includes a drawing motor, a drawing drive shaft, a drawing drive chain and a chain winch installed on the drawing drive shaft; a flipping sprocket is provided at the upper end of the guide rail, one end of the drawing drive chain is fixed on the moving platform, and the other end is fixed on the chain winch by passing through the flipping sprocket; the drawing motor drives the drawing drive shaft to rotate; the conveying sprocket at one end of the plate conveying chain provided under the guide plate is installed on the drawing drive shaft through a bearing; a pad conveying mechanism is provided under the plate conveying chain, and the pad conveying mechanism includes a conveyor belt.

[0033] The beneficial effect of adopting the above-mentioned further technical scheme is that the rod drawing motor drives the rod drawing drive shaft to rotate, and the rod drawing drive shaft drives the chain winch to rotate. The chain winch winds up the rod drawing drive chain, thereby driving the rod drawing drive chain to pull the moving platform. Since the rod drawing drive chain bypasses the sprocket at the upper end of the guide rail to connect the moving platform, the rod drawing drive chain simultaneously generates a backward pulling force on the guide rail. When a stack of plates is placed on the moving platform, the weight of the moving platform is very large, and the force required for the rod drawing drive chain to pull the moving platform is greater than the force required for the rod drawing drive chain to pull the guide rail to rotate backward. Therefore, under the action of the rod drawing drive chain, the guide rail first tilts backward onto the guide plate of the blanking mechanism, and then the moving platform slowly translates upward. When the guide rail and the mobile platform need to be reset, the strip drawing motor reverses to drive the strip drawing drive shaft to rotate in the opposite direction, and the strip drawing drive shaft drives the chain winch to rotate in the opposite direction. The chain winch lengthens the strip drawing drive chain, and the mobile platform loses the pulling force of the strip drawing drive chain, so the mobile platform slowly moves downward on the slideway. When the mobile platform moves to the lower end of the guide rail, the guide rail slowly rotates forward under the action of the gravity of the mobile platform until the guide rail is reset. The conveying sprocket of the plate conveying chain is installed on the strip drawing drive shaft through a bearing. The rotation of the strip drawing drive shaft does not affect the rotation of the plate conveying chain, and the conveying sprocket is coaxially arranged with the chain winch, which reduces the number of sprocket shafts required, optimizes the structure of the device, and saves costs. A pad conveying mechanism is provided under the plate conveying chain. The pads fall from between the plate conveying chains and directly fall onto the conveyor belt. They are transported and collected by the conveyor belt, reducing the work of manually collecting and conveying the pads.

[0034] Furthermore, the plate stacking device also includes a crossbeam, a padding strip storage bin and a padding strip release drive mechanism arranged on the stacking machine frame; the padding strip storage bin is installed on the crossbeam, and the padding strip storage bin is arranged above the lifting platform; the padding strip storage bin includes at least two padding strip frames, and the length direction of the padding strip frame is perpendicular to the crossbeam; the padding strip release drive mechanism includes a padding strip release cylinder, and the padding strip release cylinder is fixedly installed at the lower end of the padding strip frame, and the piston rod of the padding strip release cylinder extends into the padding strip frame; sliding sleeves are provided at both ends of the crossbeam, and a guide column is provided on the stacking machine frame, and the sliding sleeve is mounted on the guide column, and a crossbeam lifting cylinder is also provided at both ends of the crossbeam.

[0035] The beneficial effect of adopting the above further technical solution is that the padding strips to be stacked are stored in the padding strip frame, and the padding strip release cylinder is used to control the padding strip stacking. Each time a layer of plates is stacked on the lifting platform, the padding strip release cylinder releases the padding strips and places them on the plates, thereby realizing the automatic stacking of padding strips between the layers of the plate stack, reducing manual operations and improving work efficiency. The padding strip frame is installed on the crossbeam, and the crossbeam lifting cylinder drives the crossbeam to move up and down on the guide column to adjust the height, so that the height of the padding strip frame can be adjusted. When the height of the plate stack on the lifting platform is high and there is insufficient space for the feeding arm to push the plates, the height of the padding strip frame can be adjusted to leave space for stacking the plates.

[0036] Furthermore, the lifting platform includes a plurality of support plates, and the support plates are arranged in parallel along the length direction of the lifting platform; the plate stacking device also includes a plate stack conveying mechanism arranged below the lifting platform, and the plate stack conveying mechanism includes a plurality of rollers arranged in parallel; the rollers are arranged in the gaps between the support plates; the height of the upper end surface of the roller is higher than the height when the upper end surface of the support plate is at the lowest point.

[0037] The beneficial effect of adopting the above-mentioned further technical solution is that the stacked plates are transported to the outside of the stacking frame through the plate stack conveying mechanism, which is convenient for transportation by forklifts and other transportation tools. By arranging rollers between the gaps of the support plates, and the height of the upper end surface of the rollers is higher than the height of the upper end surface of the support plate when it is at the lowest point, when the lifting platform is translated to the lowest point, the plate stack falls from the support plate onto the rollers, and the rollers rotate to convey the plate stack.

[0080] The specific working process of stacking dried plate stacks in this embodiment is as follows:

[0081] 1. Remove the interlayer pads from the stack of boards with pads:

[0082] The stack of plates with pads is placed on the plate stack conveying chain 1.7 of the plate layer pad automatic extraction device 1 by a forklift or other conveying equipment. The plate stack conveying chain 1.7 conveys the plate stack with pads to the mobile platform 1.3. The flipping strip extraction drive mechanism drives the guide rail to flip, and then drives the mobile platform 1.3 to move upward. The plates and pads of each layer of the plate stack slide down through the blanking mechanism in turn; the plates fall onto the plate conveying chain 1.4 and are transported to the plate automatic feeding and sorting device 2; the pads fall from the idle position of the plate conveying chain 1.4 to the conveyor belt 1.8 and are transported to the pad collection place;

[0083] 2. Automatic sorting and loading of plates:

[0084] The plate is conveyed to the end of the chain, guided by the receiving plate 2.8 and falls onto the feeding chain 2.3 of the plate automatic feeding and sorting device 2. After being sorted by the feeding chain 2.3 and the stopper block 2.4, the plate is sequentially and parallelly fed to the plate quantitative conveying device 3;

[0085] 3. Quantitative separation and transportation of plates:

[0086] The plate is transported on the alignment conveyor chain, and after being arranged by the alignment rollers and baffles, the two ends of the plate are aligned, and then it is transported from the alignment conveyor chain to the conveyor chain 3.1.1 of the plate quantitative conveying device 3. When the plate is transported to the interception mechanism, the interception arm 3.3 rotates upward to intercept the plate, and the plate slips on the conveyor chain 3.1.1, and the pressing arm 3.2 rotates downward to press the plate below it; then the interception arm 3.3 rotates downward, and the plate behind the pressing arm 3.2 continues to be transported backward on the conveyor chain 3.1.1;

[0087] The sheet is transported to the top of the feeding arm 3.4, the baffle plate 3.5 blocks the sheet, the output end of the flip cylinder 3.11 extends to drive the feeding arm 3.4 to flip upward, the sheet is pushed onto the feeding arm 3.4, the feeding platform driving mechanism drives the feeding platform 3.6 to translate backward to drive the feeding arm 3.4 to translate backward, and pushes the sheet to the rear of the baffle plate 3.5, the output end of the flip cylinder 3.11 contracts to drive the feeding arm 3.4 to flip downward, the feeding platform driving mechanism drives the feeding platform 3.6 to translate forward, and as the feeding arm 3.4 translates forward with the feeding platform 3.6, the baffle plate 3.5 blocks the sheet from moving forward;

[0088] 4. Palletizing of plates:

[0089] When the feeding arm 3.4 moves backward to the rear of the material blocking plate 3.5, the feeding arm 3.4 is located above the lifting platform 4.3. At this time, the lifting platform 4.3 moves upward to the bottom of the feeding arm 3.4. When the feeding arm 3.4 moves forward, the material blocking plate 3.5 blocks the plate from moving forward and falling on the lifting platform 4.3.

[0090] The plate quantitative conveying device 3 quantitatively conveys each layer of plates to the lifting platform 4.3 of the plate stacking device 4. The lifting platform 4.3 adjusts its height to receive each layer of plates in turn and stacks the plates into stacks.

[0091] 5. Conveying of plate stacks:

[0092] After the stack of plates is completed, the lifting platform 4.3 moves horizontally downward to the lowest position, and the stack of plates falls on the rollers 4.7, which rotate to transport the stack of plates to the outside of the plate stacking device 4.

[0093] Different from the above-mentioned specific operation process, this embodiment does not need to use the automatic padding strip extraction device 1 between the plate layers to extract the strips when stacking wet plate materials that need to be stacked with padding strips. In addition, after the plate quantitative conveying device 3 conveys each layer of plate materials quantitatively to the lifting platform 4.3 of the plate stacking device 4, the padding strips on the padding strip frame 4.2.1 are released by the padding strip release cylinder 4.4 and stacked on the plate materials. The lifting platform 4.3 adjusts its height to receive each layer of plate materials in turn and stack the padding strips, and the plate materials are stacked into plate stacks with padding strips.
