Detailed Description

In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

Embodiment one:

Fig. 1 is a schematic structural diagram of an automatic tray separating and stacking device according to an embodiment of the present invention. As shown in fig. 1, a tray automatic separating and stacking device according to an embodiment of the present invention includes:

A tray removal mechanism 200 for separating individual trays 900 from a first stack 910; the disketting mechanism 200 includes: the tray stack lifting assembly 210 is configured to drive the first tray stack 910 to rise or fall; and a separation assembly 220 for preventing the descent of the tray 900 when the first tray stack 910 descends;

a tray mechanism 300 for stacking individual trays 900 from below on a second tray stack 920; and a station switching mechanism 400 for conveying individual trays 900 from the tray-removing mechanism 200 to the code tray mechanism 300.

It should be noted that the tray 900 operated in this embodiment is a plastic tray, and the plastic tray has a receiving groove to receive a corresponding product. The tray automatic separating and stacking device of the present embodiment needs to be matched with a product placement mechanism, not shown in the figure, and the product placement mechanism places the product in the accommodating groove. Generally, if a plurality of receiving slots are provided on the blister tray to receive a plurality of products, the station switching mechanism 400 transfers the blister tray filled with the products to the code tray mechanism 300 after the products are placed on all the receiving slots, so that the code tray mechanism 300 stacks the plurality of trays 900 into the second tray stack 920.

Fig. 2 is a schematic structural diagram of a tray stack lifting assembly in the tray automatic separating and stacking device according to the first embodiment of the present invention; as shown in fig. 2, the tray stack lifting assembly 210 in this embodiment includes a lifting frame 211 and a lifting driving member 212 mounted on the lifting frame 211, and in particular, the tray stack lifting driving member 212 may be a linear module. The power take off end of the tray stack lift drive 212 is fitted with a horizontal conveyor 214. The horizontal conveyor 214 cooperates with the lifting rail 215 through the lifting slider 213 to movably connect the lifting frame 211. The horizontal conveyor 214 is provided with a belt pulley driven by a motor, and the belt pulley is wound around a conveying belt, wherein one motor can drive the conveying belts of two parallel horizontal conveyors 214 to rotate. Of course, if the operator directly places the first tray stack 910 in the tray stack lifting assembly 210, the power output end of the tray stack lifting driving member 212 does not need to be connected to a member having a horizontal conveying function, so long as the first tray stack 910 can be driven to lift by connecting the horizontal bracket.

By separating the single tray 900 from the first tray stack 910, the single tray 900 may be used to load products and transported to the stacking mechanism 300 by the station switching mechanism 400, and the stacking mechanism 300 stacks the single tray 900 into the second tray stack 920 from below the second tray stack 920, so that when the tray 900 is loaded with more products, the station switching mechanism 400 supports the tray 900, and the tray 900 is prevented from being deformed greatly to cause product scattering. Moreover, the single tray 900 is stacked from the lower part of the second tray stack 920, so that the same horizontal height is always kept when the tray 900 is input to the code tray mechanism 300 by the station conversion mechanism 400, the tray 900 is not required to be moved to different heights by the station conversion mechanism 400 each time, and the tray 900 is also conveniently taken away by the station conversion mechanism 400 from the same height each time, thereby facilitating the separation of the single tray 900 and the automation of stacking the tray 900 into the second tray stack 920, improving the automation level, improving the production efficiency, reducing the operation strength of workers and saving the labor cost.

The tray automatic separating and stacking device of the present embodiment may be applied to the tray automatic separating and stacking system of the second embodiment, and cooperate with the first conveying mechanism 500 for feeding the first tray stack 910 and the second conveying mechanism 600 for removing the second tray stack 920. Instead of cooperating with the above mechanism, the first tray stack 910 may be placed in the tray stack lifting unit 210 directly by a person or by an operator operating the stacker, forklift, or the like, and the second tray stack 920 may be taken out of the tray stacking mechanism 300 by a person or by an operator operating the stacker, forklift, or the like, but the apparatus may also realize automation of the operation of separating the single tray 900 and stacking the trays 900 into the second tray stack 920, although complete automation cannot be realized. The time interval between the two placement of the first stack 910 and the two removal of the second stack 920 may be at least several minutes, which is sufficient for a worker to supply the first stack 910 and remove the second stack 920 for other automatic tray separation stacking apparatuses, thereby saving labor and improving labor efficiency.

Fig. 3 is a schematic structural diagram of a code disc mechanism in an automatic tray separating and stacking device according to a first embodiment of the present invention, in which a tray stack lifting assembly is omitted; as shown in fig. 3, the separator assembly 220 preferably includes a separator support 224 and a support drive 221, the support drive 221 being drivingly connected to the separator support 224, the separator support 224 being adapted to support the trays 900 from below the uppermost individual tray 900.

In this embodiment, the supporting driving member 221 may be an air cylinder, however, in other implementations, other linear driving members, such as a linear module, an electric push rod, or a ball screw transmission mechanism, may be used for the supporting driving member 221. In this embodiment, two separating assemblies 220 are disposed, and are respectively located outside a pair of opposite sides of the tray 900 and are fixedly mounted on the separating frame 222, and the separating frame 222 is fixedly mounted on the main frame 100. The pair of opposite sides are parallel to the line of both the position where the tray 900 is separated in the separating assembly 220 and the position where it is stacked into the second tray stack 920, in other words, the pair of opposite sides can be considered to be parallel to the direction in which the tray 900 is conveyed by the station switching mechanism 400. The power output direction of the supporting driving member 221 is perpendicular to the conveying direction of the tray 900 by the station switching mechanism 400.

In addition, in the present embodiment, the separation frames 222 are further provided with lifting upper limit sensors 223, and the lifting upper limit sensors 223 on the two separation frames 222 are respectively reflective sensors to detect the distance between the first tray stack 910 and the reflective sensors, and when the distance is smaller than a certain preset value, it can be determined that the tray stack lifting assembly 210 has driven the first tray stack 910 to lift to a position where the separation support 224 can support the uppermost tray 900.

Specifically, the power output end of the bearing driving member 221, that is, the piston rod of the air cylinder is fixedly connected with the separation bearing member 224, wherein the air cylinder can be selected from air cylinders with guiding function and capable of bearing bending moment. The separation support 224 includes a support actuator 2241 with a horizontal support ear 2242 mounted at the bottom of the support actuator 2241. Specifically, a pair of parallel horizontal support ear plates 2242 disposed at intervals may be mounted on each support transmission plate 2241, and the free ends of the horizontal support ear plates 2242 may be semicircular in shape, so as to facilitate the support ear plates to extend into the lower portion of the edge of the tray 900.

By arranging the separation supporting member 224 in transmission connection with the supporting driving member 221, the supporting driving member 221 drives the separation supporting member 224 to separate from the area where the first tray stack 910 is lifted before the tray stack lifting assembly 210 drives the first tray stack 910 to lift, so that interference is avoided. After the tray is lifted up, the support driving member 221 drives at least part of the separation support 224 to be inserted below the edge of the uppermost tray 900, and when the tray stack lifting assembly 210 drives the first tray stack 910 to descend, the uppermost tray 900 is blocked by the separation support 224 and cannot descend, so as to be separated from the rest of the trays of the first tray stack 910 below. By adopting the separation mode, the operation reliability is high, and the stable operation of the automatic separation stacking device of the material trays 900 is ensured.

FIG. 4 is a schematic view of a part of a tray automatic separating and stacking apparatus according to a first embodiment of the present invention, wherein a tray stack lifting assembly is omitted; as shown in fig. 1, 3 and 4, the tray removing mechanism 200 further preferably includes an air blowing assembly 230, wherein the air blowing assembly 230 is drivingly connected to the support driving member 221, and the air blowing assembly 230 faces between edge portions of the uppermost two trays 900 in the first tray stack 910.

Specifically, the air blowing assemblies 230 may be mounted on the supporting and driving plates 2241 of the separating and supporting member 224, two air blowing assemblies 230 are horizontally distributed on each supporting and driving plate 2241 along the direction in which the tray 900 is driven by the station switching mechanism 400, the air blowing assemblies 230 include an air blowing block 231, a plurality of air blowing holes 232 between the edge portions of the two trays 900 facing the uppermost are formed in the air blowing block 231, and the air blowing block 231 may be further connected with a compressed air source or a blower or a high-pressure blower.

Through setting up the air-blowing subassembly 230, when air-blowing subassembly 230 bloies, the air current can produce effort to first tray stack 910 top-down second tray 900 to make this tray 900 separate with the first tray 900 of top, when avoiding tray stack lifting assembly 210 to drive first tray stack 910 and descend, two trays 900 of top are because frictional force or atmospheric pressure etc. cause adhesion, thereby guarantee that only one at every turn by the tray 900 of station switching mechanism 400 transport, moreover, can not interfere with second tray 900 at every turn when station switching mechanism 400 moves to tear open tray mechanism 200, in order to improve the reliability of tray autosegregation stacking device.

As shown in fig. 1,3 and 4, the tray removing mechanism 200 further preferably includes a clamping assembly 240, wherein the clamping assembly 240 includes a clamping member 242 and a clamping driving member 241, the clamping driving member 241 is drivingly connected to the supporting driving member 221, the clamping member 242 is drivingly connected to the clamping driving member 241, and the clamping member 242 is used for clamping the tray 900 from two horizontal sides of the tray 900.

Specifically, the clamping driving member 241 may be an air cylinder, where the air cylinder may be an air cylinder with a guiding function and capable of bearing a bending moment. Of course, in other implementations, other linear drives, such as linear modules or electric push rods or ball screw drives, may be used for the clamping drive 241. The clamping driving member 241 is installed at the lower portion of the support transmission plate 2241, and a hole is formed at the middle position of the lower portion of the support transmission plate 2241 to install the clamping driving member 241. The power output end of the clamping driving member 241, i.e. the piston rod of the cylinder is fixedly connected to the separation support 224.

In the tray 900 operated in this embodiment, the side wall closest to the two edges is provided with a pit, and the clamping piece 242 may match the shape and the size of the pit. When the clamping driving member 241 drives the clamping member 242 to clamp the tray 900, not only various movements of the tray 900 in the horizontal plane can be restricted, but also upward movements of the tray 900 can be restricted because the tray 900 has solid material under the pit. In addition, the tray 900 can be prevented from moving upward only by the friction force of the holder 242 with the tray 900.

Since the trays 900 may be suction plastic, which is light in weight, when the air blowing assembly blows air to the uppermost two trays 900, the uppermost one of the trays 900 may be blown up, causing it to deviate from the home position. By arranging the clamping driving piece 241 to be in transmission connection with the clamping piece 242 so as to clamp the tray 900 from the two horizontal sides of the tray 900, the uppermost tray 900 not yet placed with products can be prevented from being blown up when the blowing assembly blows air, and the position stability of the tray 900 is ensured.

FIG. 5 is a schematic view of a tray automatic separating and stacking apparatus according to an embodiment of the present invention, wherein a separating frame is omitted compared with FIG. 4, and the tray traversing limiting assembly is partially enlarged in FIG. 5; FIG. 6 is a schematic view of a part of an automatic tray separating and stacking apparatus according to an embodiment of the present invention, wherein parts of tray and tray supporting driving members are omitted compared with FIG. 4; as shown in fig. 1 and fig. 4-6, preferably, the station switching mechanism 400 includes a translation driving member 410 and a translation supporting member 420, where the translation supporting member 420 is drivingly connected to the translation driving member 410, and the translation supporting member 420 has a hollow portion 423 penetrating in a vertical direction.

In this embodiment, the translation driving member 410 may employ a rodless cylinder. The power output end of the rodless cylinder is connected with one side of the translation support 420, which is parallel to the movement direction of the translation support 420. While the other side of the translation supporter 420 parallel to the moving direction is connected to the main frame 100 through the translation slider 440 and the translation slide 430. The translation sliding rail 430 is fixedly connected to the translation supporting member 420, and the translation sliding block 440 is matched with the translation sliding rail 430 and is fixedly mounted on the main frame 100. Of course, in alternative implementations, other linear drives, such as linear modules or electric push rods or ball screw drives, may be used for the translation drive 410.

The translation supporting member 420 includes a first rectangular supporting plate 421, where the first rectangular supporting plate 421 is square or rectangular, and has a hollowed portion 423 thereon. The hollowed portion 423 may be rectangular, kidney-shaped, or oval, etc., so that a part of the tray lifting assembly 310 described below may be penetrated therethrough to lift the tray 900 upward. Of course, in order to avoid interference between the translation bearing 420 and the separation bearing 224 in this embodiment, the translation bearing 420 further includes a second rectangular bearing plate 422, where the second rectangular bearing plate 422 is located on the bottom surface of the first rectangular bearing plate 421 and is fixedly connected to the first rectangular bearing plate 421, one side of the second rectangular bearing plate 422 is connected to the power output end of the translation driving member 410, and the other side of the second rectangular bearing plate 422 is connected to the main frame 100 through the translation sliding block 440 and the translation sliding rail 430. The middle portion of the second rectangular supporting plate 422 is further provided with a larger hollow hole, which is enough to cover the hollow portion 423, so that the material tray lifting assembly 310 can partially pass through the hollow portion, and the overall weight of the translation supporting member 420 can be reduced.

Through setting up translation bearing 420, can be steady hold tray 900 from tearing open the below that the dish mechanism 200 moved to code wheel mechanism 300, moreover because the reliable bearing of translation bearing 420, when tray 900 is on translation bearing 420, still can accept the product and place the mechanism and place the product in the holding tank of tray 900 to improve holistic automation level.

In other implementations, the workstation switching mechanism 400 may also take the form of a rotation. In the present embodiment, the tray detaching mechanism 200, the code wheel mechanism 300, and the second conveying mechanism 600 in the second embodiment are disposed substantially in line, so that the conveying directions of the trays 900 are identical among the several. If the tray removing mechanism 200 is located outside the conveying direction of the code wheel mechanism 300 and the second conveying mechanism 600, it is also conceivable to use a rotating manner to drive the tray 900 to move from the tray removing mechanism 200 to the code wheel mechanism 300. The tray 900 is driven to move in a rotating manner without a long guide rail, so that the cost of the apparatus can be reduced, but the separation assembly 220 and the lower part of the code wheel mechanism 300 are required to provide enough space for the movement of the tray 900 and the parts supporting the tray 900.

As shown in fig. 4-6, preferably, a translation limit sensor 450 is further disposed on one side of the translation support 420, and the translation limit sensor 450 is used to detect the horizontal relative position between the translation support 420 and the supported tray 900.

Specifically, the translation limit sensor 450 is a travel switch, and may be mounted on a side of the first rectangular support plate 421 facing away from the code wheel mechanism 300. When the translation supporter 420 is extended below the tray 900, since the tray 900 is clamped by the clamping assembly 240, the lower portion of the tray 900 may press the actuating member of the travel switch from the side facing the code wheel mechanism 300. When the side of the translation support 420 continues to move beyond the side of the tray 900 facing away from the code wheel mechanism 300, the actuating member of the travel switch springs upward, indicating that the translation support 420 is in place, as the upper side is no longer under pressure. Of course, in another implementation, the translation limit sensor 450 may also employ a reflective photoelectric sensor, where if the photoelectric sensor experiences no reflected signal, i.e., a reflected signal, i.e., no reflected signal, when the translation support 420 moves in a direction away from the code wheel mechanism 300, it is indicated that a side of the translation support 420 away from the code wheel mechanism 300 has passed a distance beyond a side of the tray 900 away from the code wheel mechanism 300, and the translation support 420 moves in place.

By providing the translation limit sensor 450 to detect the horizontal relative position between the translation support 420 and the supported tray 900, the translation support 420 can reliably support the tray 900, so as to prevent the tray 900 from being deformed during the transferring process, and thus, the product therein is scattered.

As shown in fig. 1 and 4-6, the code wheel mechanism 300 preferably includes a code wheel lift assembly 310, a code wheel traverse drive assembly 320, and a code wheel support assembly 330, the code wheel lift assembly 310 being configured to advance individual code wheels 900 from below a second stack 920 of code wheels into the second stack 920, and the code wheel support assembly 330 being configured to support the second stack 920 and being drivingly connected to the code wheel traverse drive assembly 320.

The code wheel lifting assembly 310 comprises a code wheel lifting driving piece 311 and a code wheel lifting piece 312, the code wheel lifting driving piece 311 can be installed on the main frame 100, the code wheel lifting driving piece 311 can be two cylinders, and the power output end of each cylinder is provided with one code wheel lifting piece 312 respectively. The cylinder can be selected from a cylinder with a guiding function and capable of bearing bending moment. Of course, in other implementations, other linear driving members, such as a linear module, an electric push rod, or a ball screw drive, may be used for the lifting/lowering driving member 311. The top end, i.e. the power output end, of the tray lifting driving member 311 is provided with a tray lifting member 312, and the tray lifting member 312 can pass through the hollowed portion 423 of the translation supporting member 420 to jack up the tray 900 upwards.

In this embodiment, two code wheel supporting assemblies 330 and two code wheel transverse driving assemblies 320 are provided, the two code wheel supporting assemblies 330 are disposed opposite to each other, and the code wheel transverse driving assemblies 320 drive the two code wheel supporting assemblies 330 to approach or separate from each other in the direction of code wheel translation.

By providing the tray support assembly 330, the second stack 920 of stacked trays can be supported by the tray support block 331, and the tray support assembly 330 is drivingly connected to the tray transverse driving assembly 320, such that the tray transverse driving assembly 320 drives the tray support assembly 330 away from each other when the second stack 920 is to be output, so that the second stack 920 can be delivered. When further stacking is desired to form the second tray stack 920, the code wheel supporting assemblies 330 may be brought closer together to support the progressively higher second tray stack 920.

As shown in fig. 4-6, the code wheel transverse drive assembly 320 preferably includes a code wheel transverse drive 321 fixedly disposed relative to the main frame 100, and the code wheel support assembly 330 includes a code wheel support transmission 336, the code wheel transverse drive 321 being drivingly connected to the code wheel support transmission 336; the code wheel mechanism 300 further includes a code wheel lateral movement limiting assembly 340, the code wheel lateral movement limiting assembly 340 includes a first lateral limiting member 341 that is relatively fixed with the main frame 100 or the code wheel supporting transmission member 336, and the code wheel lateral movement limiting assembly 340 is used for limiting the limiting positions of the two code wheel supporting assemblies 330 that are relatively arranged to be close to each other.

Specifically, in this embodiment, the transverse code wheel driving member 321 may be an air cylinder, the power output end, i.e. the piston rod, of the transverse code wheel driving member 321 is in driving connection with the supporting code wheel driving member 336, and the transverse code wheel driving member 321 is fixedly mounted on the code wheel frame 322. The code wheel support drive 336 is also movably coupled to the code wheel frame 322 by linear slides and linear slides. Wherein the linear slides are mounted on the lower surface of the upper plate portion of the code wheel support transmission 336 and the linear slides are mounted on the code wheel frame 322.

The code wheel supporting and driving member 336 further includes an outer vertical plate portion 345, and a first transverse limiting member 341 is fixedly mounted on the outer vertical plate portion 345. Specifically, the first lateral limiting member 341 may have an external thread and be in threaded connection with an internal threaded hole of the outer riser 345, and the first lateral limiting member 341 may also be in threaded connection with a lock nut. By rotating the first lateral limiter 341, the relative position of the first lateral limiter 341 between the code wheel support transmission 336 and the code wheel support transmission 336 in the direction of movement of the code wheel support transmission 336 can be adjusted and then locked by the lock nut.

By providing the first lateral stop 341 to limit the extreme positions of the two tray support assemblies 330 toward each other, a portion of the tray support assemblies 330 can be extended a sufficient distance below the edge of the tray 900 to ensure that the tray 900 is supported and prevent the tray 900 from falling.

In addition, the code wheel traversing limiting assembly 340 further comprises a first buffer member 342, wherein the first buffer member 342 may be a member such as a hydraulic buffer, the first buffer member 342 may be mounted on the outer vertical plate portion 345 in a threaded connection manner, and may also be locked by a locking nut. When the transverse code wheel driving member 321 drives the code wheel supporting assembly 330 to move inward, the first buffering member 342 can abut against the code wheel frame 322 when the code wheel supporting driving member 336 is about to move in place, and the first buffering member 342 is compressed to buffer the movement of the code wheel supporting assembly 330.

In addition, the code wheel traversing limiting assembly 340 further includes a second traversing limiting member 343, the second traversing limiting member 343 has external threads and is in threaded connection with an internal threaded hole of a limiting riser 346 fixedly mounted on the supporting frame, and the second traversing limiting member 343 may also be in threaded connection with a locking nut. By rotating the second lateral limiter 343, the relative position of the second lateral limiter 343 between the code wheel support transmission member 336 and the code wheel support transmission member 336 in the moving direction can be adjusted and then locked by the lock nut. Thereby enabling adjustment of the setting of the maximum distance position at which the code wheel supporting assembly 330 is moved outwardly.

The code wheel traverse limiting assembly 340 further comprises a second buffer member 344, wherein the second buffer member 344 may be a member such as a hydraulic buffer, and the second buffer member 344 may be mounted on the limiting riser 346 in a threaded connection manner, or may be locked by a lock nut. When the transverse code wheel driving member 321 drives the code wheel supporting assembly 330 to move inward, the second buffering member 344 can abut against the outer side surface of the code wheel supporting driving member 336 when the code wheel supporting driving member 336 is about to move in place, and the second buffering member 344 is compressed to buffer the movement of the code wheel supporting assembly 330.

The code wheel bearing assembly 330 includes a code wheel bearing block 331, the code wheel bearing block 331 is rotatably connected to a code wheel bearing bracket 333 by a bearing shaft 332, and the code wheel bearing bracket 333 is fixedly mounted on a code wheel bearing driving member 336. In addition to the support shaft 332, a compressive elastic member 334 such as a cylindrical helical compression spring is connected between the code wheel support block 331 and the code wheel support seat 333. When the tray lifting assembly 310 drives the tray 900 to lift, the tray 900 applies an upward force to the inclined surface of the tray supporting block 331, so that the tray supporting block 331 rotates against the elastic force of the elastic compressible member 334. When the tray 900 passes over the inclined plane and reaches the upper supporting surface 3311 of the tray supporting block 331, the tray supporting block 331 is restored under the action of the compressive elastic member 334, and the tray 900 is supported by the upper supporting surface 3311. The bottom of the tray supporting block 331 is abutted to the bottom of the tray supporting seat 333, and the abutted position is on the side of the supporting shaft 332 facing the second tray stack 920, so that the moment generated by the acting force of the bottom of the tray supporting seat 333 on the tray supporting block 331 can balance the moment generated by the compressive elastic member 334 and the moment generated by the tray 900, so that the tray supporting block 331 is kept in place to support the second tray stack 920.

As shown in fig. 4-6, the code wheel support assembly 330 preferably further includes a tray longitudinal stop post 335, the tray longitudinal stop post 335 being fixedly connected to the code wheel support drive 336 and adapted to limit the position of the corners of the tray 900.

Specifically, the vertical limiting columns 335 of the tray may be angle steel, which is disposed at two ends of each of the tray supporting and driving members 336 in the translation direction of the tray, and the opening directions of the four angle steel on the tray supporting and driving members 336 on two sides face the inside of the tray mechanism 300, so as to limit the positions of the corners of the tray 900.

Wherein the tray longitudinal limit column 335 is also provided with a height detection sensor 337. Because the top of the tray longitudinal limit post 335 is provided with a plurality of mounting holes with different heights to mount the height detection sensor 337, the position of the height detection sensor 337 on the tray longitudinal limit post 335 can be adjusted according to the number of trays 900 in the second tray stack 920 and the height of the trays 900 themselves, so as to adapt to the stacking height requirements of different trays 900.

By providing the tray longitudinal limit posts 335, when the trays 900 are gradually stacked into the second tray stack 920, the second tray stack 920 stacked by the trays 900 is kept vertical, and horizontal dislocation between the trays 900 of each layer does not occur, so that the second tray stack 920 is askew. Thereby ensuring the forming quality of the second tray stack 920. In addition, through with the vertical spacing post 335 of charging tray and code wheel support driving medium 336 fixed connection, when needs send second charging tray pile 920, can outwards remove along with code wheel support driving medium 336 to give up the space of sending out second charging tray pile 920, improved the convenience of operation.

The action principle of the embodiment can be referred to the action principle of the tray automatic separating and stacking system of the second embodiment, and will not be described herein.

Embodiment two:

As shown in fig. 1, the second embodiment also provides an automatic tray separating and stacking system, which includes a first conveying mechanism 500 and a second conveying mechanism 600, and an automatic tray separating and stacking device according to any of the foregoing, where the first conveying mechanism 500 is used to convey a first tray stack 910 that does not contain a product to the tray stack lifting assembly 210; the second transfer mechanism 600 is used to remove the second tray stack 920 from the code tray mechanism 300.

Fig. 7 is a schematic structural diagram of a first conveying mechanism in the tray automatic separating and stacking system according to the second embodiment of the present invention; as shown in fig. 7, the first conveying mechanism 500 includes a first conveying frame 510 and a first conveying motor 520, the first conveying motor 520 is in transmission connection with a first conveying shaft 530 through a synchronous toothed belt and a synchronous pulley, the first conveying shaft 530 drives a first conveying belt 540 through a first conveying pulley 580, and the first conveying belt 540 can support the first tray stack 910 near opposite beam edge portions at the bottom of the first tray stack 910 and drive the first tray stack 910 to move along the length direction of the first conveying mechanism 500. The first conveying mechanism 500 further includes a first conveying sensor 550 fixedly disposed with respect to the first conveying frame 510, the first conveying sensor 550 being configured to detect whether the first tray stack 910 is moved into position. In addition, the first conveying mechanism 500 further comprises a plurality of blocking driving members 560, and each blocking driving member 560 can be an air cylinder, wherein the air cylinder can be an air cylinder with a guiding function and capable of bearing bending moment. Of course, in alternative implementations, other linear drives, such as linear modules or electric push rods or ball screw drives, may be used for the blocking drive 560. While the power take-off end of the blocking drive 560 is also provided with a baffle 570. If the first tray stack 910 moves into position, the blocking drive 560 extends, driving the flap 570 to block the first tray stack 910 from further advancing, so as to prevent the first tray stack 910 from being further conveyed by the first conveyor belt 540. Even if the first transfer motor 520 malfunctions, the first tray stack 910 is not caused to be pushed away due to the blocking of the shutter 570.

Fig. 8 is a partial schematic view of an automatic tray separating and stacking system according to a second embodiment of the present invention, where fig. 8 includes a second conveying mechanism, a code tray mechanism, and a separating mechanism without a tray stack lifting assembly; as shown in fig. 8, the second conveying mechanism 600 includes a second conveying frame 610 and a second conveying motor 620, the second conveying motor 620 is in transmission connection with a second conveying shaft 630 through a synchronous toothed belt and a synchronous pulley, the second conveying shaft 630 drives a second conveying belt 640 through a second conveying pulley 660, and the second conveying belt 640 can support the second tray stack 920 near opposite beam edge portions at the bottom of the second tray stack 920 and drive the second tray stack 920 to move along the length direction of the second conveying mechanism 600. And the second conveyor 640 may extend into the code wheel mechanism 300, and when the code wheel mechanism 300 completes stacking of a certain second tray stack 920, the second tray stack 920 descends and falls onto the second conveyor 640, and may be conveyed by the second conveyor 640. The second conveying mechanism 600 further includes a second conveying sensor 650, where the second conveying sensor is fixedly disposed relative to the second conveying frame 610, and the second conveying sensor 650 is configured to detect whether the second tray stack 920 moves in place, and if so, feedback a signal to the control system, where the second conveying motor 620 stops running, and the second tray stack 920 is removed by operating the stacking machine, the forklift, etc. manually or by an operator.

The action principle of the embodiment is as follows:

An operator manually or maneuvers a fork lift, or the like, places a first stack 910 of non-product at an end of the first conveyor 500 remote from the stack lift assembly 210. Specifically, the first conveying mechanism 500 in this embodiment may accommodate four first tray stacks 910 distributed along the length direction thereof, wherein the downstream side of the three storage positions nearest to the tray stack lifting assembly 210 is provided with the blocking drive 560 and the shutter 570. Even if the position of each time the first tray stack 910 is put in is not so accurate, after the blocking driver 560 lifts the barrier 570, the first conveyor 540 may drive the first tray stacks 910 forward by a distance, for example, several seconds or tens of seconds, after the first conveyor 540 runs for a period of time, until it is blocked by the barrier 570, and the distance between the respective first tray stacks 910 may be defined by the distance between the barriers 570.

When it is desired to supply the first tray stack 910 to the tray stack lifting assembly 210, each of the blocking drivers 560 drives the flap 570 to descend. The first conveying motor 520 drives the first conveying shaft 530 through the synchronous toothed belt and the synchronous pulley, the first conveying shaft 530 drives the first conveying belt 540 to move, and the first conveying belt 540 drives the first tray stack 910 to move towards the tray stack lifting assembly 210. At the same time, the horizontal conveyor 214 of the tray stack lifting assembly 210 also starts to operate to receive the first tray stack 910 from the first conveyor belt 540. Because the tray stack lifting assembly 210 is provided with a fixed limiting member, when the horizontal conveyor 214 is continuously operated, the first tray stack 910 can be conveyed to a position abutting against the limiting member, and the first tray stack 910 can be positioned.

While the first conveyor 500 transfers the first tray stack 910 closest to the tray stack lifting assembly 210, the second and third first tray stacks 910 closest to the tray stack lifting assembly 210 on the first conveyor 540 are sequentially fed back as the first and second first tray stacks 910 due to the movement of the first conveyor 540.

Before the tray stack lifting assembly 210 starts to lift, it is required to ensure that the supporting driving member 221 drives the separating supporting member 224 to retract, and at the same time, the clamping driving member 241 drives the clamping member 242 to retract. The tray stack lifting assembly 210 starts to lift the first tray stack 910 until the lifting upper limit sensor 223 detects that the first tray stack 910 is blocked, meaning that the tray stack lifting assembly 210 moves to the highest position of lifting and conveying the first tray stack 910 in place, and the uppermost tray 900 of the first tray stack 910 is in a position that can be supported by the separation support 224.

When the first tray stack 910 moves in place, the supporting driving member 221 drives the separating supporting member 224 to extend, the supporting ear plate is also inserted under the edge portion of the tray 900, and the holding driving member 241 extends to also drive the holding member 242 to be inserted into the pit at the edge portion of the tray 900, so that the distance between the air blowing block 231 and the first tray stack 910 is shortened, and the air blowing hole 232 on the air blowing block 231 faces. The air blowing assembly 230 begins to blow air such that the uppermost two trays 900 of the first tray stack 910 are separated. Since the uppermost one of the trays 900 is gripped by the gripping member 242, the uppermost tray 900 is not blown out. Simultaneously with or after the blowing of the blowing assembly 230, the tray stack lifting assembly 210 starts to descend, thereby driving the first tray stack 910 to descend, so that the second tray 900 from top to bottom is separated from the uppermost one of the trays 900.

When the first tray stack 910 is lowered into position, the translation driving member 410 drives the translation supporting member 420 to move toward the tray lifting assembly 310. If the translation limit sensor 450 moves below a side of the tray 900 that faces the code wheel mechanism 300, the translation limit sensor 450 detects the code wheel until the tray 900 moves relative to the translation limit sensor 450 until it is no longer detected by the translation limit sensor 450, indicating that the translation support 420 is in place. Specifically, in this embodiment, the tray 900 begins to press the translation limit sensor 450 until a side of the tray 900 facing away from the code wheel mechanism 300 no longer presses the translation limit sensor 450, which proves that the translation supporter 420 is moving in place. Wherein, since the dimension of the translation bearing 420 perpendicular to the moving direction of the tray 900 is smaller than the minimum spacing of the two separation bearings 224, the separation bearings 224 will not withdraw during the insertion of the translation bearing 420 under the tray 900 to ensure reliable support of the tray 900.

After confirming that the translation support 420 is in place, the product placement mechanism is activated to place product into the receiving slot of the tray 900 and the support drive 221 is retracted to move the separation support 224 away from under the tray 900. Retraction of the support drive 221 may be prior to placement of the product by the product placement mechanism because there is now a translation support 420 to support the tray 900 to meet the product placement requirements. Of course, more stable way may be that, in the process of putting the product into the tray 900, the supporting driving member 221 and the clamping driving member 241 are not retracted, and the tray 900 is clamped by the clamping member 242, so that the position of the tray 900 in the process of putting the product is more stable, and the process of putting the product is ensured to be smoothly performed.

After the desired products are placed in the corresponding positions of the tray 900, the translation driving member 410 drives the translation supporting member 420 to move toward the tray mechanism 300 until the tray 900 is completely inserted into the tray mechanism 300. Before the tray 900 is lifted up by the tray lifting assembly 310, it is ensured that the tray transverse driving member 321 is extended. The tray lifting driving member 311 drives the tray lifting member 312 to pass through the hollow portion 423 of the translation supporting member 420, and push up the tray 900. Since the bottom of the tray longitudinal limit post 335 may form a guide space with a large bottom and a small top, even if the position of the tray 900 driven by the translation support 420 is slightly deviated, the tray 900 can be ensured to smoothly enter the area inside the tray longitudinal limit post 335.

In the process that the tray 900 is lifted by the tray lifting unit 312, the tray 900 presses a side of the tray support block 331 facing the tray lifting unit 310 upward, so that the tray support block 331 rotates relative to the tray support base 333 with the axis of the support shaft 332 as an axis, the top of the tray support block 331 moves away from the second tray stack 920, and the compressive elastic member 334 is compressed, so that the tray 900 can pass upward over the upper support surface 3311. In this process, although the upper supporting surface 3311 may be separated from the already supported second tray stack 920, the second tray stack 920 may not fall or be loosened because the lower tray 900 contacts the bottom of the second tray stack 920.

When the bottom surface of the newly entered tray 900 exceeds the upper supporting surface 3311, the compressive elastic member 334 accumulates elastic potential energy, pushing the upper portion of the tray supporting block 331 to move toward the second tray stack 920, and the upper supporting surface 3311 is located below the tray 900, so as to support the newly filled tray 900. Since the bottom of the code tray supporting block 331 is abutted against the bottom of the code tray supporting seat 333 at the side of the supporting shaft 332 facing the second tray stack 920, the moment generated by the supporting force of the bottom of the code tray supporting seat 333 to the code tray supporting block 331 can balance the moment generated by the compressive elastic member 334 and the moment generated by the tray 900, so that the code tray supporting block 331 is kept in place to support the second tray stack 920. The tray lift assembly 310 is lowered away from the lowermost tray 900 already in the second tray stack 920 and continues to descend to a position that does not interfere with the movement of the translation support 420.

The tray stack lifting assembly 210 is then raised to a position where the uppermost tray 900 of the first tray stack 910 is supported by the separation support 224, and the uppermost tray 900 of the first tray stack 910 is separated again. Of course, the raising of the tray stack lifting assembly 210 does not have to be performed after the last tray 900 has been completely stacked into the second tray stack 920. As long as the translation bearing 420 is separated from the area where the tray stack lifting assembly 210 drives the first tray stack 910 to move, the tray stack lifting assembly 210 can lift again, and the tray removing operation is continued.

When the number of trays 900 in the second tray stack 920 in the tray mechanism 300 is sufficient, that is, when the height detection sensor 337 detects the tray 900, the station switching mechanism 400 stops feeding the tray 900 into the tray mechanism 300, and the translation supporting member 420 is located at a position that does not affect the lifting of the tray lifting member 312 and drives the second tray stack 920 to lift. Specifically, the tray 900 may be located in the tray removing mechanism 200 to support the tray 900 for the product loading mechanism to load the product into the tray 900, or in a position between the tray removing mechanism 200 and the code wheel mechanism 300 that does not have the above-mentioned influence. The tray lifting driving member 311 drives the tray lifting member 312 to lift, and after the tray lifting member 312 contacts with the bottom surface of the second tray stack 920, the tray lifting member may further lift so that the bottom surface of the second tray stack 920 is higher than the upper supporting surface 3311, or the tray lifting member is not moved upwards after contacting. The code wheel transverse driving member 321 of the second tray stack 920 is retracted to drive the code wheel supporting member 330 away from the other code wheel supporting member 330, so that the minimum spacing between the two code wheel supporting blocks 331 is larger than the width of the second tray stack 920, i.e. the dimension perpendicular to the horizontal conveying direction of the trays, and the minimum spacing between the two tray longitudinal limit posts can also be larger than the width of the second tray stack 920. The tray lifting driving member 311 drives the tray lifting member 312 to descend so that both edges of the bottom surface of the second tray stack 920 fall on the second conveyor 640. Of course, the lifting and lowering assembly 310 does not necessarily need to wait for the minimum interval between the two tray longitudinal limit posts 335 to be larger than the width of the second tray stack 920, as long as the minimum interval between the two tray supporting blocks 331 is larger than the width of the second tray stack 920, and the lowering of the second tray stack 920 is not directly affected.

After the minimum interval between the two tray longitudinal limit posts 335 is also greater than the width of the second tray stack 920, and after the second tray stack 920 is lowered by the tray lifting assembly 310 into contact with the second conveyor belt 640, the second conveyor motor 620 is started, and the second conveyor shaft 630 is driven to be in driving connection by the synchronous toothed belt and the synchronous pulley, and the second conveyor shaft 630 drives the second conveyor belt 640 by the second conveyor pulley 660, so as to move the second tray stack 920 out of the tray mechanism 300. If the second transfer sensor 650 of the second transfer mechanism 600 detects the second tray stack 920, it indicates that the second tray stack 920 has been moved to a position where it can be removed, and the second transfer sensor 650 signals the control system, which prompts the operator to manually or maneuver the stacker, forklift, etc. to remove the second tray stack 920.
