Description

Technical Field

[0001] The invention relates to the technical field of wine making, in particular to an automatic stacking fixture. Background Art

[0002] In the wine-making process, after the fermented grains are steamed, koji medicine needs to be added to the fermented grains during the drying process to facilitate the subsequent fermentation in the cellar. Koji medicine is made by a koji making machine, and the koji blocks made by the koji making machine need to be fermented in the koji room. The existing koji cultivation process (i.e., the process of fermenting and storing the koji blocks after they come out of the koji making machine) has a very backward degree of automation, and the relevant operations are mainly performed manually: the koji blocks made by the koji making machine are manually picked up and placed on the corresponding racks, and then the racks are transported to the koji room for fermentation. After the fermentation of the koji blocks is completed, the koji blocks on the koji racks are moved to the pallets for bundling and packaging, and then sealed after bundling and packaging. It can be seen that manual handling of koji blocks is labor-intensive and has low work efficiency; in addition, the temperature in the koji room is as high as 50°C, and the humidity is as high as 100%. The working environment is very poor, and it is difficult to recruit workers. Summary of the invention

[0003] In order to solve the problems of high labor intensity and low efficiency in the process of manual handling and transfer of yeast blocks in the yeast culture process in the prior art, the present invention provides an automatic stacking fixture.

[0004] The technical solution adopted by the present invention is: an automatic stacking fixture, including a robot and a connecting plate, the robot is connected to the middle of the connecting plate; a stacking mechanism is provided at one end of the connecting plate, and a unloading mechanism is provided at the other end; the unloading mechanism includes a base and two parallel slides slidably connected to the bottom of the base, and the bottom of the slide is evenly provided with parallel clamps, and the distance between adjacent clamps matches the width of the block; a power mechanism for driving the slide to move is provided on the base; the stacking mechanism includes a bottom plate and side plates arranged on both sides of the bottom plate, the distance between the two side plates matches the length of the block, and a first floating clamping mechanism for clamping the block is provided on any side plate. The unloading mechanism is used to transfer the block on the block rack, and the block is fermented on the block rack. After the fermentation is completed, the block on the block rack is transported to the pallet through the stacking mechanism, and the block is bundled and packaged on the pallet, and finally stored in the warehouse. In the process of transporting the block from the koji making machine to the block rack, the power mechanism drives the two slides to move relative to each other, that is, the two slides move toward each other or back to back. When the two slides move toward each other, the curved block is clamped between the adjacent clamping plates; when the two slides move in opposite directions, it is convenient to clamp the curved block. After the curved frame is clamped by the coding mechanism, it can be placed on the curved frame by the robot. In the process of transporting the curved block from the curved frame to the pallet, the curved blocks on the curved frame are arranged at equal intervals. The robot controls the unloading mechanism to grab the curved block on the curved frame and put it on the chain conveyor. The chain conveyor is provided with a baffle. The curved block is transported on the chain conveyor and piled up at the baffle. At this time, the automatic stacking fixture is controlled to rotate 180° so that the coding mechanism faces the curved block on the chain conveyor. The robot controls the coding mechanism to grab the curved block and grabs the curved block horizontally between the two side plates. The first floating clamping mechanism clamps and fixes the curved block in the two side plates, and then the robot grabs and places the curved block on the pallet. Since the block has high humidity and low strength, the present invention clamps and fixes the block through a first floating clamping mechanism. The first floating clamping mechanism is flexibly connected to the block, which can better protect the block and prevent the clamping plate from being in electrical contact with the surface of the block due to deformation of the workpiece. The present invention can put multiple blocks on the frame and the pallet at the same time through the stacking mechanism and the unloading mechanism. The present invention replaces the traditional process of manually carrying the block to the frame through the unloading mechanism, and also replaces the traditional process of manually carrying the block from the frame to the pallet through the stacking mechanism. It has a high degree of automation, reduces labor intensity, reduces production costs, and improves production efficiency. The automatic stacking fixture of the present invention is a composite fixture that can complete the transfer of blocks in two processes on the same device. It has strong versatility, further improves production efficiency, and greatly reduces production costs.

[0005] Furthermore, the power mechanism includes a first cylinder connected to the base, the movable end of the first cylinder is hinged with the first connecting plate and the second connecting plate in sequence, the middle part of the second connecting plate is hinged with the base; one side end of the second connecting plate is hinged with a slide plate through the third connecting plate; the other side of the second connecting plate is hinged with another slide plate through the fourth connecting plate; the base is provided with a slide rail, and the slide plate is provided with a slider matching the slide rail. The slide plate and the base are connected by the slide rail, which has a simple structure, small sliding friction, and is easy to maintain later. The first cylinder of the present invention is extended and retracted to drive the first connecting plate to extend and retract, and the first connecting plate drives the second connecting plate to rotate around the hinge point, that is, the second connecting plate rotates around the base. In the process of the second connecting plate rotating, since the third connecting plate and the fourth connecting plate are distributed on both sides of the hinge point and on both sides of the second connecting plate, it is convenient to control the relative movement of the two slide plates by controlling the different rotation directions of the second connecting plate, that is, the two slide plates move towards each other or move away from each other. When the two slide plates move towards each other, the curved block is clamped between the adjacent clamping plates; when the two slide plates move away from each other, it is convenient to clamp the curved block.

[0006] Furthermore, the clamping plate is a groove-shaped structure, and the curved block can be fixed in the groove-shaped structure. The clamping plate not only has a clamping effect on the curved block, but also has a supporting effect, so the fixing effect is better.

[0007] Furthermore, the clamping plate is provided with a second floating clamping mechanism for clamping the curved block. Since the curved block coming out of the curved block making machine has high humidity and low strength, the present invention clamps the curved block through a floating clamping mechanism, and the floating clamping mechanism is flexibly connected to the curved block, which can better protect the curved block and prevent the clamping plate from being in electrical contact with the surface of the curved block due to deformation of the workpiece.

[0008] Furthermore, the second floating clamping mechanism is a diaphragm cylinder or an airbag, and the airbag is connected to the compressor through an air pipe. The diaphragm cylinder has the characteristics of short stroke, stable operation, smooth output, simple structure, etc. It is suitable for low-strength work objects and meets the clamping of the curved block in this scheme. It is flexibly connected to the curved block and can better protect the curved block. In addition, the airbag is elastic. When the curved block needs to be clamped, air is ventilated into the airbag, and the airbag bulges to clamp the curved block; the airbag meets the clamping of the curved block in this scheme, and it is flexibly connected to the curved block and can also protect the curved block.

[0009] Furthermore, an adjustment mechanism for adjusting the swing amplitude of the second connecting plate is provided on the slide plate close to the first connecting plate; the adjustment mechanism includes two supports arranged on both sides of the first connecting plate, and the supports are provided with screws threadedly connected to the supports. According to the workpieces of different sizes and the curved blocks of different sizes on site, the swing amplitude of the second connection can be adjusted by the adjustment mechanism, and then the clamping force of the clamping plate can be adjusted to match the curved block, so as to avoid the curved block from being clamped or falling, thereby improving the versatility of the device. By rotating the screw, the spacing between the two screws can be adjusted to achieve the effect of adjusting the swing amplitude of the second connection.

[0010] Furthermore, the first floating clamping mechanism is a diaphragm cylinder or an airbag, and the airbag is connected to the compressor through an air pipe. The diaphragm cylinder has the characteristics of short stroke, stable operation, smooth output, simple structure, etc. It is suitable for low-strength work objects and meets the clamping of the curved block in this scheme. It is flexibly connected to the curved block and can better protect the curved block. In addition, the airbag is elastic. When the curved block needs to be clamped, air is ventilated into the airbag, and the airbag bulges to clamp the curved block; the airbag meets the clamping of the curved block in this scheme, and it is flexibly connected to the curved block and can also protect the curved block.

[0011] Furthermore, a damping mechanism for buffering the descent of the curved block is provided on the side plate. When the unloading mechanism carries the curved block to the pallet, the first floating clamping mechanism releases the curved block, and the curved block naturally falls to the pallet below under the action of gravity. At this time, the impact force of the curved block is relatively large, and the curved block may be damaged. Therefore, the present invention provides a damping mechanism to buffer the curved block, thereby preventing the curved block from being damaged due to the large impact force during the descent process.

[0012] Furthermore, the side plate includes a long plate and a short plate, the long plate matches the height of the curved block, and the height of the short plate is less than that of the long plate; the damping mechanism includes a push plate arranged at the lower part of the long plate and parallel to the short plate, and a second cylinder driving the push plate to extend and retract toward the short plate; the fixed end of the second cylinder is fixedly connected to the long plate, and the movable end of the second cylinder is connected to the push plate. When the curved block is unloaded onto the pallet, the second cylinder drives the push plate to extend, so that the push plate approaches and contacts the curved block, and the first floating clamping mechanism is released. There is a certain friction between the curved block and the push plate, which can reduce the impact of the curved block during the descent process, play a role in buffering the curved block, and avoid damage to the curved block. Since the side plate includes a short plate and a long plate, the curved block will exceed the short plate, and the lower part of the curved block on one side of the short plate is exposed. When the curved block is placed by the unloading mechanism, the curved block in the side plate fits more closely with the curved block on the pallet, ensuring the position accuracy of the unloading and the smooth and stable setting operation.

[0013] Furthermore, a distance sensor is provided on the outer side of the short board to detect the height of the curved blocks on the pallet, thereby ensuring the position accuracy of the robot's coding and bundling and improving the safety of the system.

[0014] The beneficial effects of the present invention are:

[0015] 1. The automatic stacking fixture of the present invention replaces the traditional manual transfer process of curved blocks, has a high degree of automation, reduces labor intensity, reduces production costs, and improves production efficiency.

[0016] 2. The automatic stacking fixture of the present invention is a composite fixture, which can complete the transfer of two process blocks on the same device, has strong versatility, improves production efficiency, and greatly reduces production costs.

[0017] 3. The first floating clamping mechanism and the second floating clamping mechanism of the present invention play a role in clamping the curved block; at the same time, the floating clamping mechanism is flexibly connected to the curved block, which can better protect the curved block and prevent the clamping plate from being in electrical contact with the surface of the curved block due to deformation of the workpiece.

[0018] 4. The present invention can adjust the swing amplitude of the second connection through the adjustment mechanism, and then adjust the clamping force of the clamping plate to match the clamping force with the curved block, thereby avoiding the curved block from being damaged or falling off, and improving the versatility of the device.

[0031] Working principle: The koji unloading mechanism is used to transport the koji blocks produced by the koji making machine to the koji rack. The koji blocks are fermented on the koji rack. After fermentation, the koji blocks on the koji rack are transported to the pallet through the koji loading mechanism. The koji blocks are then bundled and packaged on the pallet and finally stored in the warehouse. In the process of transporting the koji blocks from the koji making machine to the koji rack, the power mechanism drives the two slides to move relative to each other, that is, the two slides move toward each other or away from each other. When the two slides move toward each other, the koji block is clamped between the adjacent clamping plates; when the two slides move away from each other, it is convenient to clamp the koji block. After the koji unloading mechanism clamps the koji block, it can be placed on the koji rack by the robot. In the process of transporting the curved blocks from the curved rack to the pallet, the curved blocks on the curved rack are arranged at equal intervals. The robot controls the unloading mechanism to grab the curved blocks on the curved rack onto the chain conveyor. The chain conveyor is provided with a baffle. The curved blocks are transported on the chain conveyor and piled up at the baffle. At this time, the automatic stacking fixture is controlled to rotate 180° so that the stacking mechanism faces the curved blocks on the chain conveyor. The robot controls the stacking mechanism to grab the curved blocks and grab the curved blocks horizontally between the two side plates. The first floating clamping mechanism clamps and fixes the curved blocks in the two side plates, and then the robot grabs and places the curved blocks into the pallet. Since the humidity of the curved blocks is high and the strength of the curved blocks is not high, the present invention clamps and fixes the curved blocks by the first floating clamping mechanism. The first floating clamping mechanism is flexibly connected to the curved blocks, which can better protect the curved blocks and prevent the clamping plate from being in contact with the surface of the curved blocks due to deformation of the workpiece. The present invention can put multiple curved blocks on the curved rack and the pallet at the same time through the stacking mechanism and the unloading mechanism. The present invention replaces the traditional manual process of carrying the block to the rack through the unloading mechanism, and also replaces the traditional manual process of carrying the block on the rack to the pallet through the stacking mechanism, which has a high degree of automation, reduces labor intensity, reduces production costs, and improves production efficiency; the automatic stacking fixture of the present invention is a composite fixture, which can complete the transfer of blocks in two processes on the same device, has strong versatility, further improves production efficiency, and greatly reduces production costs. The robot adopts ABB's IRB6700 model robot.

[0032] Reference Figure 4The power mechanism of this embodiment includes a first cylinder 41 connected to the base, and the movable end of the first cylinder 41 is hinged with a first connecting plate 42 and a second connecting plate 43 in sequence, and the middle part of the second connecting plate 43 is hinged with the base 21; one side end of the second connecting plate is hinged with a slide plate through a third connecting plate 44; the other side of the second connecting plate is hinged with another slide plate through a fourth connecting plate 45; a slide rail 201 is provided on the base 21, and a slider 202 matching the slide rail is provided on the slide plate 22. The slide plate and the base are connected by means of a slide rail, which has a simple structure, small sliding friction, and is easy to maintain later. The first cylinder of the present invention is extended and retracted to drive the first connecting plate to extend and retract, and the first connecting plate drives the second connecting plate to rotate around the hinge point, that is, the second connecting plate rotates around the base. In the process of the second connecting plate rotating, since the third connecting plate and the fourth connecting plate are distributed on both sides of the hinge point and on both sides of the second connecting plate, it is convenient to control the relative movement of the two slide plates by controlling the different rotation directions of the second connecting plate, that is, the two slide plates move towards each other or back to back. When the two slide plates move toward each other, the curved block is clamped between adjacent clamping plates; when the two slide plates move away from each other, it is convenient to clamp the curved block.

[0033] Reference Figure 1 The clamping plate 23 of this embodiment is a groove-shaped structure. The clamping plate not only has a clamping effect on the curved block, but also has a supporting effect, so the fixing effect is better.

[0034] The clamping plate 23 of this embodiment is provided with a second floating clamping mechanism 203 for clamping the curved block; the second floating clamping mechanism 203 is a diaphragm cylinder. Since the curved block coming out of the curved machine has a high humidity and low strength, the present invention clamps the curved block through a floating clamping mechanism. The floating clamping mechanism is flexibly connected to the curved block, which can better protect the curved block and prevent the clamping plate from being in electrical contact with the surface of the curved block due to deformation of the workpiece. The diaphragm cylinder has the characteristics of short stroke, stable operation, smooth output, and simple structure. It is suitable for low-strength work objects and meets the requirements for clamping the curved block of this scheme. It is flexibly connected to the curved block, which can better protect the curved block.

[0035] Reference Figure 1 In this embodiment, an adjustment mechanism for adjusting the swing amplitude of the second connection plate is provided on the slide plate 22 near the first connection plate; the adjustment mechanism includes two supports 51 arranged on both sides of the first connection plate 42, and the supports 51 are provided with screws 52 threadedly connected to the supports. According to the workpieces of different sizes and the curved blocks of different sizes on site, the swing amplitude of the second connection can be adjusted by the adjustment mechanism, and then the clamping force of the clamping plate can be adjusted to match the curved block, so as to avoid the curved block from being clamped or falling, thereby improving the versatility of the device. By rotating the screw, the spacing between the two screws can be adjusted to achieve the effect of adjusting the swing amplitude of the second connection.

[0036] The first floating clamping mechanism 34 in this embodiment is a diaphragm cylinder, which has the characteristics of short stroke, stable operation, smooth output, and simple structure. It is suitable for work objects with low strength and can meet the clamping of the curved block in this solution. It is flexibly connected to the curved block, which can better protect the curved block.

[0037] The base, slide plate, and clamping plate in this embodiment are all made of stainless steel sheet material, which are precision machined after welding to ensure accuracy and strength, and also have the characteristic of light weight, which can reduce the load of the robot.

[0038] The base in this embodiment is in a "ji" shape, and reinforcing ribs are provided on the base to make space for the curved block holding mechanism; the reinforcing ribs further enhance the stability of the base.

[0039] Embodiment Two

[0040] Refer to Figure 1 and Figure 3 On the basis of Embodiment One, a damping mechanism for buffering the descent of the curved block is provided on the side plate in this embodiment; the side plate includes a long plate 33 and a short plate 32. The height of the long plate 33 matches the height of the curved block, and the height of the short plate 32 is less than the height of the long plate 33; the damping mechanism includes a push plate 61 provided at the lower part of the long plate 33 and parallel to the short plate 32, and a second cylinder 62 for driving the push plate to extend and retract towards the short plate; the fixed end of the second cylinder is fixedly connected to the long plate 33, and the movable end of the second cylinder is connected to the push plate 61.

[0041] Working principle: When the curved block unloading mechanism transports the curved block to the tray, the first floating clamping mechanism releases the curved block. Under the action of gravity, the curved block naturally drops onto the lower tray. At this time, the impact force of the curved block is relatively large, and the curved block may be damaged. Therefore, in the present invention, a damping mechanism is provided to buffer the curved block and avoid damage to the curved block due to a large impact force during the descent. When unloading the curved block onto the tray, the second cylinder drives the push plate to extend, so that the push plate approaches and contacts the curved block. The first floating clamping mechanism releases, and there is a certain frictional force between the curved block and the push plate, which can reduce the impact force during the descent of the curved block and play a role in buffering the curved block to avoid damage to the curved block. Since the side plate includes a short plate and a long plate, the curved block will extend beyond the short plate, and the lower part of the curved block on one side of the short plate is in an exposed state. When the curved block unloading mechanism places the curved block, the curved block inside the side plate fits more closely with the curved block on the tray, ensuring the position accuracy of unloading the curved block and the smooth and stable operation of the setting.

[0042] Refer to Figure 1 and Figure 3 In this embodiment, a distance sensor 7 is provided outside the short plate 32, which can detect the height of the curved block on the tray, ensure the position accuracy of the robot's curved block stacking and bundling, and improve the safety of the system.

[0043] Embodiment Three

[0044] The difference between this embodiment and the first embodiment is that the structure of the second floating clamping mechanism 203 is different. The second floating clamping mechanism 203 of this embodiment is an airbag, which is connected to the compressor through an air pipe. The airbag is elastic. When the curved block needs to be clamped, air is ventilated into the airbag, and the airbag swells to clamp the curved block; the airbag meets the clamping requirements of the curved block in this solution, and is flexibly connected to the curved block to protect the curved block.

[0045] Embodiment 4

[0046] The difference between this embodiment and the first embodiment is that the structure of the first floating clamping mechanism 34 is different. The first floating clamping mechanism 34 of this embodiment is an air bag, which is connected to the compressor through an air pipe. The air bag is elastic. When the curved block needs to be clamped, air is ventilated into the air bag, and the air bag swells to clamp the curved block. The air bag meets the clamping requirements of the curved block in this solution, and is flexibly connected to the curved block to protect the curved block.
