Description

Technical Field

[0001] The invention relates to the technical field of pallet recovery, and in particular to an empty pallet recovery device. Background Art

[0002] The bracket provides a stable platform for material transmission, which keeps the material stable during the transportation process and makes material transmission more convenient. By using the bracket, it can be easily loaded, unloaded and transported by forklifts and manipulators, thus improving the operation efficiency.

[0003] Among them, wooden brackets are widely used in various production scenarios because of their strong shock absorption and sound insulation effects and lower cost;

[0004] In the prior art, after the materials are transferred on the conveying equipment, the wooden pallets require a large number of people to carry and stack them, and there is no mature equipment that can automatically recycle and stack the wooden pallets, which reduces the production efficiency and increases the labor cost;

[0005] Moreover, in actual use and storage, since wooden pallets are made of wood, if they are used improperly and come into contact with too much moisture, or if the manufacturing enterprise is located in the south or other humid areas, the wooden pallets will be affected by moisture. After being affected by moisture, the wooden pallets are prone to rot, thus becoming more fragile. The existing technology is unable to inspect the wooden pallets when recycling and stacking the pallets. When the wooden pallets are stacked high, if the rotten wooden pallets are at the bottom, the rotten wooden pallets will be damaged and deformed due to excessive pressure, which will cause the materials to tip over during transportation, leading to safety accidents.

DETAILED DESCRIPTION

[0042] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] Example 1

[0044] An empty pallet recovery device, such as Figure 1-18 As shown, it includes a support leg 1, a surrounding frame 2, a limiting frame 3 and an entrance 4; a plurality of support legs 1 are fixedly connected to the surrounding frame 2, and the surrounding frame 2 is provided with an entrance 4; the surrounding frame 2 is fixedly connected to the limiting frame 3;

[0045] It also includes a driving motor 101, a conveying chain 102, a supporting plate 103, a base 111, a lifting frame 112, a screw motor 113, a bottom plate 114 and a bracket assembly; the frame 2 is fixedly connected to the driving motor 101, and the output shaft of the driving motor 101 passes through the frame 2; the frame 2 is fixedly connected to the conveying chain 102, and the conveying chain 102 shaft is fixedly connected to the output shaft of the driving motor 101; the frame 2 is fixedly connected to the supporting plate 103; all the legs 1 are fixedly connected to a bottom plate 114; the bottom plate 114 is fixedly connected to The base 111 is slidably connected to a lifting frame 112, and the lifting frame 112 is provided with a threaded rod; the base 111 is fixedly connected to a screw motor 113, and the threaded rod of the lifting frame 112 is connected to the working part of the screw motor 113; the surrounding frame 2 is fixedly connected to two plug-in assemblies arranged front and back facing each other, and the lifting frame 112 is located between the two plug-in assemblies, and the lifting frame 112 is located between the two chains of the conveying chain 102, and the two plug-in assemblies are located above the lifting frame 112 and the entrance 4, and the size of each plug-in assembly is set according to the actual working space.

[0046] The support assembly behind the limiting frame 3 includes a support plate 121, a first electric push rod 122, a fixed plate 123, an insertion strip 124, a first electric slide rail 125 and a first electric slider 126; the limiting frame 3 is fixedly connected to the support plate 121; the limiting frame 3 is fixedly connected to the first electric push rod 122, and the first electric push rod 122 runs through the limiting frame 3; the limiting frame 3 and the support plate 121 are jointly fixedly connected to two first electric slide rails 125; each first electric slide rail 125 is slidably connected to a first electric slider 126; all the first electric slide rails 125 are jointly fixedly connected to a fixed plate 123; the fixed plate 123 is fixedly connected to two insertion strips 124.

[0047] It also includes a limiting component; the surrounding frame 2 is fixedly connected to two limiting components that are symmetrically arranged on the left and right.

[0048] The limiting assembly on the left side of the entrance 4 includes a second electric push rod 201, a hollow arc plate 202, an air inlet pipe 203 and an elastic sheet 204; the frame 2 is fixedly connected to the second electric push rod 201; the second electric push rod 201 is fixedly connected to the hollow arc plate 202; the hollow arc plate 202 is fixedly connected to the elastic sheet 204; the hollow arc plate 202 is fixedly connected to the air inlet pipe 203, and the air inlet pipe 203 is connected to the cavity formed by the hollow arc plate 202 and the elastic sheet 204.

[0049] Before the device is put into operation, all air inlet pipes 203 are connected to the external air supply equipment;

[0050] Then, the to-be-processed bracket 5 is transported to the entrance 4 by the transport device. During the transport of the to-be-processed bracket 5, the position of the to-be-processed bracket 5 is adjusted manually or mechanically to prevent the to-be-processed bracket 5 from deviating too much and failing to smoothly enter the enclosure 2 from the entrance 4, thereby affecting the subsequent palletizing work;

[0051] When the bracket 5 to be processed enters the enclosure 2 from the entrance 4, the driving motor 101 starts to work, and the driving motor 101 drives the connected conveying chain 102 to start rotating. After the bracket 5 to be processed enters the entrance 4, the bracket 5 to be processed contacts the conveying chain 102, and then the bracket 5 to be processed continues to be transported to the inside of the enclosure 2 through the conveying chain 102. When the bracket 5 to be processed is transported to the preset position (directly above the lifting frame 112), the screw motor 113 starts to work, and the screw motor 113 drives the connected lifting frame 112 to move upward until the through hole on the side of the bracket 5 to be processed is aligned with the insertion strip 124. At this time, the first electric push rod 122 starts to work, and the telescopic part of the first electric push rod 122 drives the connected fixed plate 123 to move toward the direction of the bracket 5 to be processed. The movement of the fixed plate 123 drives the connected insertion strip 124 to move until the insertion strip 124 enters the through hole of the bracket 5 to be processed;

[0052] At this time, the screw motor 113 starts to work in the reverse direction, driving the lifting frame 112 to reset, and at this time, the bracket 5 to be processed is supported by the front and rear inserts 124, so it will not fall off;

[0053] Afterwards, the subsequent bracket 5 to be processed will also be brought to the preset position through the conveyor chain 102. At this time, the screw motor 113 works forward again, driving the lifting frame 112 to move upward until the subsequent bracket 5 to be processed contacts the first bracket 5 to be processed, and at this time the first electric push rod 122 is reset, driving the insertion bar 124 to reset, so that the insertion bar 124 no longer supports the first bracket 5 to be processed, and the first bracket 5 to be processed is now supported by the subsequent bracket 5 to be processed. More specifically, the two brackets 5 to be processed are now supported by the lifting frame 112 in a stacked state;

[0054] At this time, the lifting frame 112 is still moving. When the through hole of the subsequent bracket 5 to be processed is aligned with the insertion strip 124, the first electric push rod 122 works forward again until the insertion strip 124 enters the through hole of the subsequent bracket 5 to be processed, and then the screw motor 113 drives the lifting frame 112 to reset, so that the insertion strip 124 completes the support work of the two stacked brackets 5 to be processed, and thus a working cycle is completed. After that, the insertion strip 124 and the lifting frame 112 repeatedly cooperate to complete the stacking work of several brackets 5 to be processed. When the brackets 5 to be processed are stacked to a preset height, the several brackets 5 to be processed are stacked into a bracket pile, and the device stops working, and then the bracket pile can be transferred away by a forklift or a mechanical arm or other equipment;

[0055] Furthermore, when the to-be-processed bracket 5 is being transported by the transport device, although the position has been corrected, the transport device itself will vibrate to a certain extent, and the to-be-processed bracket 5 will be slightly offset. When the bracket pile is not high, the slight offset of the to-be-processed bracket 5 will not affect the palletizing work. However, when the bracket pile is high, each to-be-processed bracket 5 will be slightly offset, which will cause the bracket pile to topple.

[0056] The prior art usually sets a limit block to fine-tune the bracket 5 to be processed. However, after long-term use, the length, width and height of each bracket 5 to be processed will have certain deviations. If the width of the bracket 5 to be processed in the left and right directions increases, the friction of the existing limit block on the bracket 5 to be processed will be too large, resulting in the conveyor chain 102 being unable to drive the bracket 5 to be processed to move. If the width of the bracket 5 to be processed in the left and right directions decreases, the existing limit block will not be able to play a limiting role.

[0057] Therefore, the device is also provided with a limit position component. Before the bracket 5 to be processed enters the enclosure 2 from the entrance 4, the second electric push rod 201 starts to work and pushes the hollow arc plate 202, the air inlet pipe 203 and the elastic sheet 204 to move toward the center direction of the entrance 4 until the elastic sheet 204 contacts the left side or right side corresponding to the bracket 5 to be processed. Then the external air supply device starts to work and introduces air into the cavity formed by the hollow arc plate 202 and the elastic sheet 204. The air pressure in the cavity increases due to the air blowing, and the elastic sheet 204 will swell. After swelling, the elastic sheet 204 can correct the bracket 5 to be processed, and due to the elastic setting of the elastic sheet 204, there will be no strong friction force on the bracket 5 to be processed. In this way, the conveying chain 102 can also normally transport the bracket 5 to be processed, and the elastic sheet 204 is used to limit the correction of the bracket 5 to be processed, thereby avoiding the problem that each bracket 5 to be processed cannot be accurately corrected by using a general limit block.

[0058] Example 2

[0059] On the basis of Example 1, Fig.11 and Fig.12 As shown,

[0060] It also includes a second electric slide rail 301, a second electric slider 302, a connecting rod 303 and a pressure plate 304; the surrounding frame 2 and the limiting frame 3 are fixedly connected to a second electric slide rail 301; the second electric slide rail 301 is slidably connected to the second electric slider 302; the second electric slider 302 is fixedly connected to the connecting rod 303; the connecting rod 303 is fixedly connected to the pressure plate 304.

[0061] It also includes a third electric slider 311, an adjustment frame 312, an air port 3121, a deformation grinding sheet 3122, a conduit 3123, an air cavity 3124 and a steering component; the second electric slide rail 301 is slidably connected to the third electric slider 311; the third electric slider 311 is connected to the adjustment frame 312 through the steering component, and the adjustment frame 312 is hollow, and the inner side surface of the adjustment frame 312 is open, and the upper and lower parts of the inner side surface of the adjustment frame 312 are inclined; each inclined surface of the adjustment frame 312 is provided with a plurality of air ports 3121, and each air port 3121 is provided with a built-in valve; the adjustment frame 312 is fixedly connected to the deformation grinding sheet 3122; the adjustment frame 312 and the deformation grinding sheet 3122 surround the air cavity 3124; the adjustment frame 312 is fixedly connected to the conduit 3123, and the conduit 3123 is connected to the air cavity 3124.

[0062] The adjustment frame 312 is provided with a heating component, and the heating component cooperates with the air port 3121 to dry the bracket 5 to be processed, so that the service life of the bracket 5 to be processed is extended.

[0063] Before the device is put into operation, the conduit 3123 is connected to the external air pump;

[0064] During the stacking process of the brackets 5 to be processed, when the brackets 5 to be processed are stacked high, the bracket stack of the brackets 5 to be processed will inevitably shake due to the work of the parts;

[0065] Therefore, when the first-entered to-be-processed bracket 5 is driven to move upward by the lifting frame 112, the second electric slide rail 301 starts to work, and drives the second electric slide block 302, the connecting rod 303 and the pressing plate 304 to move downward in sequence. When the pressing plate 304 contacts the upper surface of the first-entered to-be-processed bracket 5, the subsequent to-be-processed bracket 5 pushes the first-entered to-be-processed bracket 5 upward. At this time, the second electric slide rail 301 works accordingly, driving the pressing plate 304 to move upward. In this process, the pressing plate 304 always contacts the upper surface of the first-entered to-be-processed bracket 5 and applies pressure to its upper surface, so as to further ensure the stability of the bracket stack.

[0066] When the bracket 5 to be processed is being stacked and the insert strip 124 is not in operation, the second electric slide rail 301 drives the connected third electric slider 311 to move upward, and the third electric slider 311 drives the steering component, the adjustment frame 312, the deformation grinding sheet 3122 and the guide tube 3123 to move upward in sequence. The inner side surface of the adjustment frame 312 and the outer side surface of the bracket 5 to be processed are in a clearance fit relationship. The bracket 5 to be processed with a displacement in position is limited and corrected by the inclined surface of the adjustment frame 312 during the upward movement of the adjustment frame 312, thereby further ensuring the stability of the bracket stack;

[0067] When the adjusting frame 312 starts to move upward, the external air pump connected to the guide tube 3123 starts to work and introduces air into the air cavity 3124. At this time, the air pressure in the air cavity 3124 becomes high, and the deformable grinding sheet 3122 is squeezed and bulged by the air. At this time, the deformable grinding sheet 3122 can grind the outer side of the bracket 5 to be processed during the movement of the adjusting frame 312, so that the burrs generated by the bracket 5 to be processed during use can be removed. On the one hand, the burrs are prevented from causing damage to the materials supported on the bracket 5 to be processed (such as bagged particles and general fruits, etc.), and on the other hand, the burrs of the bracket 5 to be processed can be avoided, which may cause punctures to the hands of the staff who subsequently contact the bracket 5 to be processed.

[0068] When the air enters the air cavity 3124, the air will be ejected from the air port 3121 to blow away the debris polished on the bracket 5 to be processed, thereby ensuring the cleanliness of the surface of the bracket 5 to be processed, so that the subsequent use of the bracket 5 to be processed will not be affected by the debris, and during the air jetting process of the air port 3121, the heating component of the adjustment frame 312 starts to work, thereby heating the air in the air cavity 3124. At this time, the air port 3121 ejects hot air, so that the surface of the bracket 5 to be processed can be blown and dried, ensuring that the bracket 5 to be processed is dry before storage or use, thereby extending the service life of the bracket 5 to be processed;

[0069] Furthermore, within a fixed time, the total air output of all the air ports 3121 is less than the total amount of air introduced by the external air pump, so that the air ports 3121 will not affect the operation of the deformable grinding sheet 3122 .

[0074] Each detection strip includes an air guide bend 408, a needle 409 and a hollow telescopic strip 4010; the mounting plate 407 is fixedly connected to the air guide bend 408, and the air guide bend 408 passes through the mounting plate 407; the air guide bend 408 passes through the hollow rotating rod 402 and is connected to the rod cavity 403; the end of the air guide bend 408 away from the hollow rotating rod 402 is a vertical portion; the vertical portion of the air guide bend 408 is fixedly connected to the hollow telescopic strip 4010; the hollow telescopic strip 4010 is fixedly connected to the needle 409, and the contact portion between the hollow telescopic strip 4010 and the needle 409 is in a closed state, and the pointed portion of the needle 409 is more prominent than the curved teeth of the curved rack 406.

[0075] The steering component includes an annular slide rail 313 and a curved slider 314 ; the third electric slider 311 is fixedly connected to the annular slide rail 313 ; the annular slide rail 313 is slidably connected to the curved slider 314 ; the curved slider 314 is fixedly connected to the adjustment frame 312 .

[0076] Before the device is put into operation, all hollow rotating rods 402 are connected to an external pump, and the air pressure detector 405 is connected to an external alarm device for communication;

[0077] In actual use, the brackets 5 to be processed will be placed on the ground or used in an environment with many metal parts. At this time, the surface of the brackets 5 to be processed will be pierced with solid foreign objects (such as sharp stones and nails, etc.), especially the solid foreign objects on the upper and lower surfaces, which will cause the brackets 5 to be processed to tilt when they are stacked, causing the bracket stack to fall over;

[0078] Therefore, the device is provided with two thorn removal assemblies. Before the bracket 5 to be processed enters the enclosure 2 from the entrance 4, the two DD motors 404 start to work. The two DD motors 404 drive the connected hollow rotating rods 402 to rotate clockwise from the right to the left. The two hollow rotating rods 402 drive other parts of the two thorn removal assemblies to rotate. Before the bracket 5 to be processed enters the enclosure 2 from the entrance 4, the bracket 5 to be processed will first pass through the thorn removal assembly.

[0079] (For the convenience of description, the following description is made by taking the upper thorn removal assembly as an example. The lower thorn removal assembly is symmetrically identical to the upper thorn removal assembly in structure. The only difference is that the upper thorn removal assembly processes the upper surface of the bracket 5 to be processed, while the upper thorn removal assembly processes the lower surface of the bracket 5 to be processed. The two thorn removal assemblies achieve the same effect.)

[0080] When the bracket 5 to be processed passes through the thorn removal component, the convex surface of the rotating curved rack 406 will contact the upper surface of the bracket 5 to be processed, and the curved rack 406 is still rotating. At this time, if there is a hard foreign object pierced on the upper surface of the bracket 5 to be processed, a shallow foreign object (such as a sharp stone) will be directly picked up by the tip of the curved teeth of the curved rack 406, and a deep foreign object (such as a nail) will be first picked up by the tip of the curved teeth, so that there is a certain gap between the top of the deep foreign object and the upper surface of the bracket 5 to be processed, and then as the curved rack 406 continues to rotate, the top of the deep foreign object is picked up. The part will be stuck in the V-shaped gap of the curved teeth of the curved rack 406, and then the curved rack 406 continues to rotate to pull out the deeply embedded foreign matter, so that the solid foreign matter embedded in the upper surface of the bracket 5 to be processed can be removed, thereby avoiding the problem that the surface of the bracket 5 to be processed will be pierced by solid foreign matter, especially the solid foreign matter on the upper surface and the lower surface, which will cause the bracket 5 to be processed to tilt when stacking, causing the bracket stack to topple, making the stacking of the bracket 5 to be processed more stable and ensuring the subsequent normal use of the bracket 5 to be processed;

[0081] When the curved rack 406 rotates, a rough portion 4061 is provided on the convex surface of the curved rack 406. The rough portion 4061 can grind the upper surface of the bracket 5 to be processed when the curved rack 406 rotates, so that the burrs on the surface of the bracket 5 to be processed are further processed.

[0082] In actual use, the bracket 5 to be processed may be exposed to excessive moisture due to improper use, or the production enterprise may be located in the south or other humid areas, which may cause the bracket 5 to be processed to rot. If the rotten bracket 5 to be processed is located at the bottom of the bracket pile, the rotten bracket 5 to be processed may be damaged and deformed due to excessive pressure, which may cause the material to fall during transportation, thereby causing a safety accident.

[0083] Therefore, a detection strip is provided on the thorn removal component. Before the convex surface of the curved rack 406 contacts the upper surface of the bracket 5 to be processed, the upper surface of the bracket 5 to be processed will first contact the thorn needle 409 in the detection strip. Before the bracket 5 to be processed contacts the thorn needle 409, the external pump starts to work, and introduces air into the rod cavity 403 of the hollow rotating rod 402. The rod cavity 403 introduces air into the air guide bend 408. The air enters the hollow telescopic strip 4010 from the air guide bend 408. Thereafter, the hollow telescopic strip 4010 is unfolded, and the hollow telescopic strip 4010 pushes the thorn needle 409 to unfold as shown in the figure. Fig.18 state, and at this time the air pressure detector 405 records the pressure value in the rod cavity 403 to obtain the unfolding pressure value, and the air pressure detector 405 continuously records the pressure value in the rod cavity 403 when the detection strip is working;

[0084] When the upper surface of the bracket 5 to be processed contacts the needles 409, if the contact portion of the upper surface of the bracket 5 to be processed with each needle 409 is a normal area (the area is not corrupted and has a harder texture), all the needles 409 will be supported by the normal area, and at this time the needles 409 are driven to rotate by the hollow rotating rod 402, and the needles 409 cannot penetrate into the normal area, and the needles 409 will be retracted into the air guide elbow 408 under the top of the normal area and move toward the hollow telescopic strip 4010. The needles 409 compress the hollow telescopic strip 4010 when moving, and the air in the hollow telescopic strip 4010 will be compressed. At this time, since the hollow telescopic strip 4010, the air guide elbow 408 and the rod cavity 403 are connected, the pressure in the rod cavity 403 will increase, and the air pressure detector 405 will detect that the pressure in the rod cavity 403 has changed, and obtain a normal pressure change value. At this time, the bracket 5 to be processed can be normally sent to the enclosure 2 for subsequent work;

[0085] If the upper surface of the bracket 5 to be treated that contacts the part of the needles 409 is a corroded area (the corroded area will be softer), the needles 409 will not be held by the corroded area and move toward the hollow telescopic strip 4010, and there are two situations at this time;

[0086] Case 1: Only a small part of the needle 409 will not retract into the air guide elbow 408 (indicating that only a small part of the bracket 5 to be treated is corroded, but it can still be used). At this time, the pressure value in the rod cavity 403 will be abnormal, but the pressure value in the rod cavity 403 changes little.

[0087] At this time, the air pressure detector 405 will send the first information to the second electric slide rail 301. The second electric slide rail 301, which receives the first information, will start to work and drive the third electric slide block 311 to move downward when the bracket 5 to be processed is pushed upward by the lifting frame 112, until the bracket 5 to be processed is located between the inner sides of the adjustment frame 312.

[0088] After that, the external air pump connected to the conduit 3123 starts to work efficiently, and the built-in valves of all the air ports 3121 are closed, and the air is introduced into the air cavity 3124 of the adjustment frame 312. At this time, the deformation grinding sheet 3122 protrudes and bulges more. After the deformation grinding sheet 3122 protrudes and bulges, it clamps the bracket 5 to be processed.

[0089] At this time, the annular slide rail 313 starts to work, driving the curved slider 314 to start rotating 180 degrees counterclockwise around the annular slide rail 313 from a top-down perspective, so that the bracket 5 to be processed is now outside the enclosure 2. At this time, the second electric slide rail 301 continues to work to drive the third electric slider 311 to move upward, thereby driving the bracket 5 to be processed to move.

[0090] Until the bracket 5 to be processed is moved to the top of the bracket pile, the curved slider 314 drives the annular slide rail 313 to reset, and the bracket 5 to be processed is located directly above the bracket pile. At this time, the external air pump stops working, and the bracket 5 to be processed is separated from the adjustment frame 312 and falls to the top of the bracket pile. In this way, the defective bracket 5 to be processed, which is less corroded and can still be used, can be transferred to the top of the bracket pile. On the one hand, the defective bracket 5 to be processed will not be squeezed, damaged or deformed at the bottom of the bracket pile, and the defective bracket 5 to be processed is located at the top of the bracket pile, which is higher from the ground and more difficult to be corroded by water vapor, so that the service life of the defective bracket 5 to be processed is longer.

[0091] Case 2: Most of the needles 409 will not retract into the air guide bend 408 (indicating that most of the bracket 5 to be processed is corroded and cannot be used anymore), but the pressure value in the rod cavity 403 changes greatly. At this time, the air pressure detector 405 will send a second message to the external alarm device, and notify the staff or machinery to remove the bracket 5 to be processed through the external alarm device, so that the damaged bracket 5 to be processed that is severely corroded and cannot be used anymore can be transferred in time and will not affect the stacking of subsequent bracket piles.

[0092] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
