Description

Technical Field

[0001] The present invention relates to the technical field of palletizing devices, and in particular to a palletizing device and a method thereof for palletizing long and large materials. Background Art

[0002] An automated warehouse is a system that can automatically store and retrieve materials without direct manual processing. It mainly includes shelves, stackers, inbound (outbound) workbenches, automatic inbound (outbound) conveyor belts, and operation control systems.

[0003] Chinese invention patent CN105600258A discloses a high-bay warehouse stacker and an automated high-bay warehouse. The stacker's horizontal movement is achieved by forming a walking trolley through a track installed on the ground, a horizontal motion mechanism, and a frame. The vertical movement of the support platform is achieved by a vertical motion mechanism installed on the gantry and the frame. The fork is used to achieve bidirectional extension and retraction along the direction of the warehouse, significantly reducing manufacturing and operating costs.

[0004] The above-mentioned device uses a fork to take out and put in the goods. However, in actual use, there is no corresponding limit on the distance the fork is extended. Although the longer the distance the fork is extended, the more stable the goods are when lifting, the greater the wear and tear on the fork is. How to control the distance the fork is extended according to the size of the goods is not involved in the above-mentioned solution. In summary, the above-mentioned device still has room for improvement.

[0005] Therefore, it is necessary to provide a stacking equipment and method for long and large materials to solve the above technical problems. Summary of the Invention

Although the longer the distance the fork is extended, the more stable the goods are when being lifted, the greater the wear and tear of the fork is.

[0007] Based on the above ideas, the present invention provides the following technical solution: a stacking device for long and large materials, comprising a bracket and a loading platform slidably engaged with the bracket, a telescopic fork mounted on the top of the loading platform, side plates fixedly mounted on both sides of the upper fork arm of the telescopic fork, a stopper rod slidably mounted on the top surface of the side plate, and a slide rod slidably engaged with the side plate disposed below the stopper rod;

[0008] One end of the slide rod is rotatably engaged with a positioning rod, and the positioning rod and the slide rod are elastically connected. A pull rope is fixedly arranged between the barrier rod and the slide rod. When the barrier rod is attached to one side of the cargo and the upper fork arm moves relative to the cargo, the barrier rod can pull the slide rod through the pull rope to make it slide outward relative to the side plate. When the positioning rod passes over the cargo, the positioning rod can deflect upward relative to the slide rod and cause the telescopic fork to stop extending.

[0009] As a further solution of the present invention: a slide groove is provided on the top surface of the side panel, a guide block is fixedly provided inside the slide groove near one end of the upper fork arm, one end of the pull rope is fixedly connected to the barrier rod, and the other end of the pull rope passes through the guide block and extends to the end of the slide rod away from the positioning rod and is fixedly connected to the slide rod.

[0010] As a further solution of the present invention: an arc-shaped guide rod is fixedly provided on the end face of the positioning rod close to the sliding rod, the guide rod extends into the sliding rod at one end away from the positioning rod and slides with it, a protrusion is integrally formed on the end of the guide rod away from the positioning rod, and the sliding rod is provided with a mounting groove that slides with the guide rod and the protrusion, and a switch is installed in the inner cavity of the mounting groove close to the end face of the positioning rod, and the switch is electrically connected to the motor that drives the telescopic fork to operate.

[0011] As a further solution of the present invention: a stop block is elastically installed on the side of the slide rod, the stop block is made of iron, and magnetic strips are fixedly embedded on the front and rear sides of the inner cavity of the slide groove, and the magnetic strips are arranged on one end of the side plate close to the positioning rod.

[0012] As a further solution of the present invention: a plurality of strip grooves are evenly opened on both side surfaces of the slide rod, and a clamping strip matching the strip grooves is elastically installed on the side plate.

[0013] As a further solution of the present invention: the bottom surface of the inner cavity of the chute is configured as an inclined surface.

[0014] As a further solution of the present invention: the end of the positioning rod away from the sliding rod is a curved structure and forms a guide portion.

[0015] As a further solution of the present invention: the end of the slide close to the baffle is an open structure, the cross section of the slide is a "cross" shape, the baffle is set as a T shape as a whole, and the bottom end of the baffle is slidably set in the slide.

[0016] As a further solution of the present invention: the cross section of the installation groove is set to be a "cross" shape.

[0017] A method for stacking using the above-mentioned stacking equipment for long and large materials includes the following steps: moving the loading platform to one side of the designated goods, causing the telescopic fork on the top of the loading platform to extend under the goods; when the barrier bar is in contact with one side of the goods and the upper fork arm and the side plate move under the goods, the slide bar can slide outward relative to the side plate, and when the positioning bar passes over the goods and deflects upward relative to the slide bar, the telescopic fork stops running.

[0018] Compared with the prior art, the beneficial effect of the present invention is that: this device uses the sliding rod to set up, and when the barrier rod contacts one side of the cargo and the upper fork arm moves at the bottom of the cargo, the sliding rod can move outward relative to the side plate, so that when one end of the upper fork arm passes the center of the cargo, the positioning rod can pass over the cargo and rotate upward relative to the sliding rod, so that the positioning rod can be stuck on the other side of the cargo. At this time, the cargo is stuck between the barrier rod and the positioning rod, making the cargo more stable during transportation, and when the positioning rod rotates upward to the side of the cargo, the telescopic fork also stops extending and retracting. Therefore, it is possible to minimize the extension distance of the upper fork arm while ensuring stable lifting of the cargo, which is beneficial to protecting the telescopic fork.

DETAILED DESCRIPTION

[0033] like Figure 1-4 As shown, a stacking equipment and method for long and large materials include a bracket 1 and a loading platform 3 that slides with the bracket 1. A telescopic fork 4 is installed on the top of the loading platform 3. Of course, the loading platform 3 also needs to be equipped with relevant moving parts for driving the telescopic fork 4 to work, such as a motor, a reducer, and an encoder. Since the structure of the telescopic fork 4 is relatively common, it will not be described in detail here.

[0034] In order to drive the bracket 1 to move, in actual application, a slide rail 5 can be installed on the floor of the warehouse, and a slider 6 that slides with the slide rail 5 can be fixedly provided on the bottom surface of the bracket 1. Specifically, the bracket 1 can be driven to move on the slide rail 5 by the cooperation of the gear and the rack, that is, a rack is fixedly installed on the slide rail 5, and the bracket 1 is provided with a gear driven by a motor and meshing with the rack. Of course, the bracket 1 can also be driven to move by chain drive. Since it is a mature technical means in the mechanical field, it will not be elaborated here.

[0035] During actual use, the driving bracket 1 moves to the goods 13 to be taken out, the loading platform 3 is raised to the side of the corresponding goods 13, and the loading platform 3 is placed under the goods 13. Then, the telescopic fork 4 can be driven to extend so that the upper fork arm 401 of the telescopic fork 4 moves to the bottom of the goods 13. When the loading platform 3 moves upward again, the telescopic fork 4 can lift the goods 13 so that the goods 13 can leave the shelf. When the telescopic fork 4 retracts, the goods 13 can be driven onto the loading platform 3.

[0036] During specific application, as the telescopic fork 4 continues to extend, the pressure it bears will gradually increase. Therefore, the guide structures such as the rollers on the telescopic fork 4 will also be damaged. However, one end of the upper fork arm 401 of the telescopic fork 4 must exceed the center of gravity or the center of the cargo 13 during the movement, so that the cargo 13 can be lifted stably. In order to minimize the distance that the upper fork arm 401 extends, the present solution is fixed with side plates 12 on both sides of the upper fork arm 401. The top surface of the side plate 12 is slidably equipped with a stop rod 7, and a slide bar 11 is provided below the stop rod 7. The slide bar 11 is slidably matched with the side plate 12. One end of the slide bar 11 is rotatably matched with the positioning rod 10. When the blocking rod 7 on the upper fork arm 401 is attached to one side of the cargo 13 and the upper fork arm 401 moves a certain distance relative to the cargo 13, the slide bar 11 moves the same distance relative to the upper fork arm 401. Through the structure, when one end of the telescopic fork 4 passes the center position of the cargo 13, the positioning rod 10 at one end of the slide bar 11 can move to the other side of the cargo 13 and deflect relative to the slide bar 11. The deflection of the positioning rod 10 relative to the slide bar 11 can control the motor that drives the telescopic fork 4, thereby controlling the distance moved by the upper fork arm 401.

[0037] like Figure 2-6 As shown, a slide groove 1201 is provided on the top surface of the side plate 12. The end of the slide groove 1201 close to the stop bar 7 is an open structure. The cross section of the slide groove 1201 is a "cross" shape. Figure 5 As shown, the barrier rod 7 is configured as a T-shape as a whole, and the bottom end portion of the barrier rod 7 is slidably disposed in the slide groove 1201. Through the configuration of this structure, the barrier rod 7 can only slide in the horizontal direction relative to the side plate 12 and cannot move in the vertical direction relative to the side plate 12. A pull rope 8 is fixedly disposed between the barrier rod 7 and the slide rod 11.

[0038] Specifically, a guide block 9 is fixedly provided inside the slide groove 1201 near one end of the upper fork arm 401, one end of the pull rope 8 is fixedly connected to the barrier rod 7, the other end of the pull rope 8 passes through the guide block 9 and slides with it, and one end of the pull rope 8 passes through the guide block 9 and is fixedly connected to the end of the slide rod 11 away from the positioning rod 10. Through this structure, when the barrier rod 7 is attached to one side of the cargo 13 and the upper fork arm 401 moves relative to the cargo 13, the barrier rod 7 can pull the slide rod 11 through the pull rope 8 to make it slide outward relative to the side panel 12.

[0039] Reference Figure 6-11 As shown, an arc-shaped guide rod 18 is fixedly provided on the end surface of the positioning rod 10 close to the slide rod 11. The end of the guide rod 18 away from the positioning rod 10 extends into the slide rod 11 and slides with it. The center of the arc-shaped guide rod 18 is on the same straight line as the rotation center of the positioning rod 10. Figure 9As shown, a protrusion 1801 is integrally formed on the end of the guide rod 18 away from the positioning rod 10, and a mounting groove 1801 is provided on the slide rod 11 for slidingly cooperating with the guide rod 18. The cross-section of the mounting groove is set to a "cross" shape. A switch 17 can be installed at the end face of the inner cavity of the mounting groove near the positioning rod 10. When the positioning rod 10 completely passes over the cargo 13, the positioning rod 10 can bounce upward. When the protrusion 1801 on the guide rod 18 contacts the inner cavity end face of the mounting groove, the positioning rod 10 stops rotating. At this time, the protrusion 1801 contacts the switch 17. The above-mentioned switch 17 can be electrically connected to an external alarm, so that when the protrusion 1801 contacts the switch 17, it can alert the staff, and the staff can control the motor at the telescopic fork 4. Of course, the above-mentioned switch 17 also directly controls the motor at the telescopic fork 4 through electrical connection or signal connection. The specific circuit connection structure is a mature technical means in the electrical field and will not be elaborated here.

[0040] In order to lock the positioning rod 10 after rotation, this solution has a stopper 14 elastically installed on the side of the slide rod 11. The stopper 14 is made of iron, and a magnetic strip 16 is fixedly embedded on both the front and rear sides of the inner cavity of the slide groove 1201. The magnetic strip 16 is set at one end of the side plate 12 close to the positioning rod 10. When the slide rod 11 drives the positioning rod 10 to move out of the slide groove 1201 and the magnetic strip 16 is completely staggered with the stopper 14, the stopper 14 has a tendency to pop out. When the positioning rod 10 rotates relative to the slide rod 11 so that the guide rod 10 When one end of the rod 18 is located at the end face of the inner cavity of the installation groove, the guide rod 18 is staggered with the stop block 14. At this time, the stop block 14 can pop out and be placed at the end of the guide rod 18. At this time, the protrusion 1801 on the guide rod 18 is placed between the end face of the installation groove and the stop block 14, so that the positioning rod 10 is locked. Through this structure, when the positioning rod 10 passes over the cargo 13 and rotates upward, the positioning rod 10 can be placed on one side of the cargo 13 and limit it, thereby improving the stability of the cargo 13 during transportation.

[0041] In order to lock the sliding rod 11 in the sliding groove 1201, in actual application, a plurality of strip grooves 1104 can be evenly opened on both sides of the sliding rod 11, and a clip 22 that cooperates with the strip groove 1104 is elastically installed on the side panel 12. When the clip 22 pops out and is inserted into the strip groove 1104, the sliding rod 11 is locked in the sliding groove 1201.

[0042] During the actual picking process, first move the bracket 1 to the side of the corresponding goods 13, and lift the loading platform 3 to the bottom of the side of the goods 13. Figure 4As shown, the telescopic fork 4 is driven to extend, and during this process, the side plate 12 will also move synchronously with the upper fork arm 401. When the blocking rod 7 on the top of the side plate 12 contacts one side of the cargo 13, it will stop moving. At this time, when the upper fork arm 401 and the side plate 12 continue to move at the bottom of the cargo 13, the blocking rod 7 can move relative to the side plate 12 in the direction away from the positioning rod 10, and the set pull rope 8 makes it possible to pull the slide bar 11 during the movement of the blocking rod 7 relative to the side plate 12, thereby prompting the slide bar 11 and the positioning rod 10 at one end thereof to move. The positioning rod 10 slides in the slide groove 1201. Specifically, when the positioning rod 10 moves a certain distance relative to the side plate 12, the slide bar 11 also moves outward relative to the side plate 12 by the same distance. Therefore, when one end of the upper fork arm 401 passes over the center of the cargo 13, the positioning rod 10 can move to the other side of the cargo 13. When the positioning rod 10 passes over the cargo 13, the positioning rod 10 can rotate upward relative to the slide bar 11 and finally fit into the cargo 13. At this point, the cargo 13 is stuck between the positioning rod 10 and the blocking rod 7.

[0043] When the guide rod 18 is lifted up, the guide rod 18 is moved back to the position where the stopper 14 is located, and the stopper 14 is moved back to the position where the guide rod 18 is located.

[0044] Afterwards, the loading platform 3 is lifted up again and the goods 13 are lifted off the shelf by the upper fork arm 401. As the upper fork arm 401 retracts, the goods 13 can be driven onto the loading platform 3. When the bracket 1 moves the goods 13 to the designated unloading area, the telescopic fork 4 can be extended again. When the goods 13 are delivered to the designated area, the loading platform 3 moves downward so that the positioning rod 10 and the blocking rod 7 are staggered with the goods 13, which is conducive to retracting the slide bar 11 and the positioning rod 10 into the slide groove 1201. When the end of the slide bar 11 closes the positioning rod 10 and gradually moves into the inside of the slide groove 1201, the suction force of the magnetic strip 16 on the block 14 can make it staggered with the guide rod 18, so that the positioning rod 10 can rotate relative to the slide bar 11. As the slide bar 11 moves completely into the slide groove 1201, the side plate 12 squeezes the positioning rod 10 so that it can gradually rotate to a horizontal state and retract into the slide groove 1201.

[0045] To sum up, this device is provided with a slide bar 11. When the barrier bar 7 contacts one side of the cargo 13 and the upper fork arm 401 moves at the bottom of the cargo 13, the slide bar 11 can move outward relative to the side plate 12, so that when one end of the upper fork arm 401 passes over the center of the cargo 13, the positioning bar 10 can pass over the cargo 13 and rotate upward relative to the slide bar 11, so that the positioning bar 10 can be stuck on the other side of the cargo 13. At this time, the cargo 13 is stuck between the barrier bar 7 and the positioning bar 10, making the cargo 13 more stable during transportation, and when the positioning bar 10 rotates upward to the side of the cargo 13, the telescopic fork 4 also stops extending and retracting. Therefore, it is more able to minimize the extension distance of the upper fork arm 401 while ensuring stable lifting of the cargo 13, which is beneficial to protecting the telescopic fork 4.

[0046] like Figure 1-3 As shown, in order for the slide bar 11 to be retracted into the slide groove 1201, in actual use, after unloading is completed, the staff can push it back, but for the convenience of operation, a method of retracting the slide bar 11 is given here. Specifically, the bottom surface of the inner cavity of the above-mentioned slide groove 1201 can be set as an inclined slope 1202, and the bottom surface of the slide bar 11 can be installed with balls to reduce the friction between the slide bar 11 and the side panel 12. In actual use, when the blocking rod 7 and the positioning rod 10 are staggered with the cargo 13, the slide bar 11 can slide downward along the slope 1202, thereby pulling the positioning rod 10 back into the slide groove 1201.

[0047] like Figure 1As shown, in actual use, the loading platform 3 can be driven by a chain to move up and down along the bracket 1. In addition, a lifting motor can be arranged under the bracket 1, and the output shaft of the lifting motor is connected to the reel. A traction rope 2 is fixed between the reel and the loading platform 3. Of course, a pulley is installed at the top of the bracket 1 so that the traction rope 2 passes around the outside of the pulley. In actual use, guide wheels can also be installed on the loading platform 3, and the guide wheels are clamped on both sides of the bracket 1 to improve the stability of the movement of the loading platform 3.

[0048] Reference Figure 3 As shown, a joint can be fixedly installed on the end of the slide rod 11 away from the positioning rod 10, thereby facilitating the fixed connection between the pull rope 8 and the slide rod 11.

[0049] Reference Figure 6 As shown, the positioning rod 10 is fixedly provided with two sleeves 1001 at one end close to the sliding rod 11, and a rod sleeve 1101 is provided between the two sleeves 1001. The rod sleeve 1101 is fixedly connected to the sliding rod 11, and a connecting rod 1102 is coaxially provided in the rod sleeve 1101. The connecting rod 1102 and the rod sleeve 1101 are rotatably engaged. The end of the connecting rod 1102 away from the rod sleeve 1101 extends into the sleeve 1001 and is rotatably connected thereto. A circular shaft 1103 is fixedly provided at the end faces of both ends of the connecting rod 1102, and a first coil spring 15 is sleeved on the outside of the circular shaft 1103. The two ends of the first coil spring 15 are respectively fixedly connected to the inner wall of the sleeve 1001 and the outer wall of the circular shaft 1103. Through this structure, the positioning rod 10 and the sliding rod 11 are elastically engaged and the positioning rod 10 can rotate relative to the sliding rod 11.

[0050] Reference Figure 7 As shown, a through hole connected to the mounting groove is provided on the slide rod 11, a rectangular groove is provided on the inner wall of the through hole, and a protrusion 1401 that slides with the rectangular groove is fixedly provided on the stop block 14, and a first spring is fixedly provided between the protrusion 1401 and the inner end face of the rectangular groove.

[0051] Reference Figure 10-12 As shown, a boss is fixedly provided on the side panel 12 at the position of the clamping strip 22, and a connecting block 20 is provided above the boss. Specifically, a vertical rod is fixedly provided on the top surface of the boss, and the vertical rod extends into the connecting block 20 and slides with it. A second spring is fixedly provided between the connecting block 20 and the boss, and a pressure block 19 is hinged on the side of the connecting block 20 close to the side panel 12. Specifically, a rotating shaft is fixedly provided on the connecting block 20, and a mounting hole matching the rotating shaft is provided on the pressure block 19. The cross-section of the mounting hole is set to T-shape, so that one end of the rotating shaft extends into the mounting hole and rotates with it. In addition, a second coil spring is also sleeved on the outside of the rotating shaft, and the two ends of the second coil spring are respectively fixedly connected to the outer wall of the rotating shaft and the inner wall of the mounting hole.

[0052] A magnetic plate 21 is fixedly embedded on the side of the pressure block 19 close to the side panel 12, and a magnetic block that matches the magnetic plate 21 is fixedly embedded on the end of the clamping strip 22 away from the slide bar 11. The opposite side of the magnetic block and the magnetic plate 21 have the same magnetic pole. Through this structure, when the upper fork arm 401 moves upward and lifts the cargo 13, the cargo 13 will squeeze the connecting block 20 downward. When the magnetic plate 21 is aligned with the magnetic block, it can push the clamping strip 22 close to the slide bar 11, thereby locking the slide bar 11 in the slide groove 1201.

[0053] The side plate 12 is provided with a through slot that is slidably engaged with the clamping strip 22 . A baffle is fixedly provided at the end surface of the through slot away from the slide rod 11 , and a spring is fixedly provided between the baffle and the clamping strip 22 .

[0054] In actual use, one end of the positioning rod 10 away from the sliding rod 11 can be bent to form a guide portion 1002, thereby preventing the positioning rod 10 from interfering with the cargo 13 when moving at the bottom of the cargo 13.
