Description

Technical Field

[0001] The invention relates to the technical field of cargo handling, and in particular to a fully automatic and efficient loading and unloading device for box-type cargo. Background Art

[0002] For the transportation of box cargo, currently most of them use slings or forklifts. When using slings, first tie the box securely with ropes, then use the sling to suspend it in the air for transportation, while forklifts use shovels to directly act on the bottom of the box to fork it up, and then transport it to the destination. Sling transportation requires personnel to tie and untie ropes, which is time-consuming and labor-intensive. During the operation, forklifts act on one side of the bottom of the box, so it is not convenient to fork it directly. Instead, external force is required to tilt the box or hold it against the box first, and the forklift is also prone to damage the box in the process of forking the box.

[0003] The above two handling methods are not only inefficient, but also relatively simple in mode. When faced with goods of different weights, they also lack flexibility in actual use. Therefore, it is necessary to propose a fully automatic and efficient loading and unloading device for box-type goods. Summary of the invention

[0010] Preferably, two vacuum suction cups are slidably mounted on the bottom plate;

[0011] A sliding groove is provided on the surface of the bottom plate corresponding to the sliding track of the vacuum suction cup. Two guide rods are arranged at the upper end of the bottom plate corresponding to the position of each suction cup frame. The suction cup frame is slidably connected to the two guide rods. Two springs are also connected to each guide rod. One end of the spring is connected to the bushing that fixes the guide rod, and the other end is connected to the outer wall of the suction cup frame.

[0012] Preferably, each vacuum suction cup is arranged through the bottom plate, and a suction cup frame is also provided on the upper end surface of the bottom plate for installing the vacuum suction cup, and vacuum suction cup avoidance grooves are opened at the positions of the suction cup frames on both sides of the lifting plate.

[0016] Preferably, a clamping plate avoidance groove is provided on the plate surface of the bottom plate, and the clamping plate avoidance groove is located between the limiting column and the threaded rod and is larger than the width of the clamping plate;

[0021] Compared with the prior art, the present invention provides a fully automatic and efficient loading and unloading device for box-type cargo, which has the following beneficial effects:

[0022] (1) The loading and unloading device proposed in the present invention has three operation modes, which can be selected according to the different weights of goods. When the goods are light, they can be directly suspended and transported by two vacuum suction cups, and the two clamps do not need to move. When the goods are heavy, but can be suspended from the ground by the vacuum suction cups, the shovels at the bottom of the two clamps can be used to support the box. The top of the box is fixed by the two vacuum suction cups, and the bottom is supported by the two shovels. During the suspension and transportation process, there will be no relative shaking with the loading and unloading device, which can ensure the safety of loading and unloading. When the weight of the goods is greater than the adsorption force of the two vacuum suction cups, the two clamps can be rotated to a vertical state first, and then the two clamps can move toward each other in the horizontal direction, and the two shovels can be used to apply force to both sides of the bottom of the box, so that the box can be forked smoothly. Compared with the unilateral forking of the forklift, the operation method of the present application makes it easier to fork the box, and then the two vacuum suction cups adsorb the top of the box again to ensure the stability of the box.

[0023] (2) The two clamping plates in the present invention can move synchronously toward or away from each other in the horizontal direction and can also be extended and retracted in the vertical direction, so that the device can be applied to boxes of different sizes, further improving the application range of the device.

[0024] (3) In addition, the two vacuum suction cups in the present invention adopt a floating design, and both can slide in the horizontal direction. Since the present invention adopts a combination of vacuum suction cups and clamps when fixing the box, when the vacuum suction cup first moves to adsorb the top of the box, and then the two shovels move toward the box to support its bottom, the suspension equipment needs to be able to accurately move the device to the top of the box, and also ensure that the distance between the box and the clamps on both sides is the same. The vacuum suction cups in the present invention adopt a floating design. Even if the position of the device relative to the box deviates, the two clamps will still generate a force on the box during the movement, so that the box is automatically centered relative to the bottom plate, and the two shovels will still be accurately supported on the bottom of the box.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

[0035] like Figure 1As shown in Figure 7, this embodiment proposes a fully automatic and efficient loading and unloading device for box-type cargo, including a base plate 1, on the surface of which two vacuum suction cups 10 are installed. For lighter cargo (the weight of the cargo does not exceed the maximum adsorption force of the vacuum suction cup 10), the cargo can be directly adsorbed and suspended by the two vacuum suction cups 10 for transportation. However, for safety during transportation, this embodiment also has two clamping plates 9 rotatably installed on both sides of the base plate 1. The two clamping plates 9 are synchronously flipped downward and move toward the box body a. A shovel plate 19 is also connected to the bottom of each clamping plate 9, and the two shovel plates 19 are arranged facing each other. When the two clamping plates 9 are flipped downward to a vertical state, the two shovel plates 19 at this time just move to the bottom of the box body a to support it, thereby preventing the box body a from separating from the two vacuum suction cups 10.

[0036] Specifically, in the above scheme, the two clamping plates 9 rotate relative to the bottom plate 1. In order to achieve synchronous movement of the two, a mounting frame 21 is installed at the positions corresponding to the clamping plates 9 on both sides of the bottom plate 1 in this embodiment. The top of the mounting frame 21 is rotated with a rotating shaft, and a gear 23 is fixedly sleeved in the middle of the rotating shaft. The top of the clamping plate 9 is fixedly connected to the circumferential surface of the rotating shaft through two short plates. The gear 23 is distributed between the two short plates and does not contact the clamping plate 9 to avoid motion interference. The two gears 23 are driven to rotate synchronously by external force, thereby driving the clamping plate 9 to swing around the rotating shaft.

[0037] Furthermore, in this embodiment, four support columns 8 are fixed on the upper end surface of the bottom plate 1 in the vertical direction, and the top ends of the four support columns 8 are connected to the top plate 3. A lifting plate 2 is arranged between the bottom plate 1 and the top plate 3, and the lifting plate 2 is slidably sleeved on the four support columns 8. A cylinder 7 is installed on the top of the top plate 3, and the piston rod of the cylinder 7 penetrates the top plate 3 and is fixedly connected to the center of the lifting plate 2. A linear rack 27 is arranged on the plate surface of the lifting plate 2 in the vertical direction at the position corresponding to each gear 23, and the linear rack 27 is meshed with the corresponding gear 23. The lifting plate 2 is driven by the cylinder 7 to slide between the bottom plate 1 and the top plate 3, thereby driving the linear rack 27 to move in the vertical direction, and the gear 23 is meshed with the corresponding linear rack 27 to drive the clamping plate 9 to rotate.

[0038] It should be pointed out in particular that since the lifting plate 2 moves in the vertical direction, two vacuum suction cups 10 are installed on the surface of the base plate 1, each vacuum suction cup 10 is arranged through the base plate 1, and a suction cup frame 12 is also provided on the upper end surface of the base plate 1 for installing the vacuum suction cup 10. Therefore, in order to avoid the lifting plate 2 from interfering with the suction cup frame 12 when moving in the vertical direction, vacuum suction cup avoidance grooves 30 are opened on both sides of the lifting plate 2 at the positions corresponding to the suction cup frames 12.

[0039] The whole device is installed on the suspension equipment when in use, such as Figure 1As shown, two support plates 4 are fixed to the upper end of the top plate 3, and the tops of the two support plates 4 are connected into an integrated structure by a connecting strip 5. The middle part of the connecting strip 5 is rotatably installed with a rotating shaft 6, and the rotating shaft 6 is fixed to the suspension device. After the suspension device suspends the device and moves it to the top of the box a, the suspension device lowers the device, and the two vacuum suction cups 10 first contact the upper end surface of the box a. The two vacuum suction cups 10 work to adsorb the box a, and then the suspension device suspends the device, and the box a is lifted off the ground. At this time, the cylinder 7 is started to drive the lifting plate 2 to move upward, and the linear rack 27 engages with the gear 23 to drive the two clamps 9 to rotate toward the box a. After the clamp 9 rotates to a vertical state, the shovel plate 19 at its bottom is just supported on the bottom of the box a, and finally the suspension device transports the box a to the destination.

[0040] In the actual operation process, if two clamps 9 are needed to clamp the box a, then the suspension equipment is required to accurately move the entire device to the top of the box a, that is, to ensure that the distance between the box a and the clamps 9 on both sides is the same. This requires personnel to have higher requirements on the operating accuracy of the suspension equipment. Otherwise, once the device deviates, the two clamps 9 will not be able to support and fix the box a normally. Based on this, the present embodiment chooses to slide and install two vacuum suction cups 10 on the bottom plate 1. Specifically, a slide groove 18 is provided on the plate surface of the bottom plate 1 corresponding to the sliding track of the vacuum suction cup 10. Two guide rods 13 are provided at the upper end of the bottom plate 1 corresponding to the position of each suction cup frame 12. The suction cup frame 12 is slidably sleeved with the two guide rods 13. Two springs 14 are sleeved on each guide rod 13. One end of the spring 14 is connected to a liner for fixing the guide rod 13, and the other end is connected to the outer wall of the suction cup frame 12. The two vacuum suction cups 10 become a floating design through the above structure. When the suspension device drives the device to move above the box a, since the connecting bar 5 and the rotating shaft 6 can rotate, the personnel can first hold the entire device to rotate and adjust it, and adjust the entire device to be consistent with the direction of the box a, so as to attach Figure 1 For example, the length direction of the bottom plate 1 is adjusted to be parallel to the length direction of the box a, and the distance between the middle of the box a and the two clamps 9 is not adjusted. The two vacuum suction cups 10 are started to adsorb the box a and lift the box a off the ground under the action of the suspension equipment. At this time, the two clamps 9 are driven to move toward the box a synchronously. Since the two vacuum suction cups 10 can slide in the horizontal direction, the two clamps 9 act on the side of the box a to drive it to slide adaptively during the synchronous movement, and finally the two linear racks 27 are supported on the lower side of the box a, which is equivalent to the automatic centering of the clamps 9.

[0041] In addition, the device in this embodiment has to face boxes a of different specifications during operation. In order to improve its scope of application, this embodiment first sets the two clamps 9 to be telescopic, and a cylinder 25 is installed on the back of each clamp 9 along its length direction. The side of the shovel plate 19 that contacts the clamp 9 is fixedly connected with two connecting rods 26. The two connecting rods 26 extend into the interior of the clamp 9 and are slidably connected thereto. The piston rod of the cylinder 25 is fixedly connected to the shovel plate 19, and the shovel plate 19 is driven by the cylinder 25 in a direction away from the clamp 9, thereby achieving the extension of the clamp 9 to adapt to boxes a of different heights.

[0042] When facing boxes a of different widths, this embodiment slides the two mounting frames 21 on the base plate 1. Specifically, the bottoms of both sides of the two mounting frames 21 are integrally formed with sliders 24, and the upper end of the base plate 1 is provided with limit columns 15 and threaded rods 17 corresponding to the sliding direction of the mounting frames 21, wherein the limit columns 15 are fixedly connected to the base plate 1, and the threaded rods 17 are connected to the rotation, and are driven to rotate by the motor 16 on the base plate 1, and the sliders 24 on both sides of each mounting frame 21 are respectively sleeved on the limit columns 15 and the threaded rods 17, wherein one slider 24 is slidingly connected to the limit column 15, and the other slider 24 is threadedly connected to the threaded rod 17, and the thread directions of the two sliders 24 threadedly connected to the threaded rod 17 remain opposite, so that the motor 16 can drive the mounting frames 21 to move toward or away from each other synchronously, so as to adapt to boxes a of different widths. When the width of the box a is small, the two mounting frames 21 move toward each other synchronously, and the clamping plate 9 moves toward the bottom plate 1 along with the mounting frames 21. In order to prevent the clamping plate 9 from being blocked by the bottom plate 1 when moving, a clamping plate avoidance groove 11 is provided on the board surface of the bottom plate 1. The clamping plate avoidance groove 11 is located between the limiting column 15 and the threaded rod 17 and is larger than the width of the clamping plate 9. At the same time, since the two mounting frames 21 move in opposite directions or toward each other, the lifting plate 2 moves in the vertical direction. Therefore, in order to avoid interference between the mounting frames 21 and the lifting plate 2, the present embodiment further provides a limiting sliding groove 29 on the board surface of the lifting plate 2. The limiting sliding groove 29 is adapted to the width of the mounting frames 21.

[0043] When the mounting frame 21 is adjusted in the horizontal direction, the linear rack 27 needs to cooperate with the synchronous movement therewith, therefore, an adjusting slider 28 is slidably installed on the inner side of the limiting slide 29, and the adjusting slider 28 is slidably sleeved on the slide rail 31 inside the limiting slide 29, and the inner side end of the mounting frame 21 is fixedly connected with the column 22 along the setting direction, and the column 22 extends upward to penetrate the adjusting slider 28 and is slidably connected therewith, so that when the distance between the two mounting frames 21 in the horizontal direction is adjusted, the relative positions of the linear rack 27 and the gear 23 remain unchanged, and the linear rack 27 can always move synchronously with the lifting plate 2 in the vertical direction, ensuring that the linear rack 27 and the gear 23 can always mesh normally. It is also necessary to explain the length of the limiting slide 29. When the two mounting frames 21 move toward each other until the clamping plate 9 contacts the inner side of the clamping plate avoidance groove 11, the two mounting frames 21 move to the limit position, and the adjusting slider 28 just contacts the inner side of the limiting slide 29.

[0044] In addition, since the two mounting frames 21 of the present invention can adjust the distance between them horizontally to adapt to boxes a of different widths, the functionality of the entire device can be further improved. When the weight of the goods inside the box a is very large and it cannot be suspended by the adsorption force of the vacuum suction cup 10, the two clamping plates 9 can be directly inserted into the bottom of the box a to fork it. During the specific operation, the distance between the two clamping plates 9 is first adjusted according to the width of the box a, so that when the two clamping plates 9 are in a vertical state, the distance between the two shovel plates 19 is slightly larger than the width of the box a, and the cylinder 7 is started. Drive the two clamps 9 to rotate to a vertical state, then start the motor 16 to drive the two mounting frames 21 to move toward each other, and fork the box a through the two shovel plates 19. At this time, the piston rods of the two oil cylinders 25 retract, driving the bottom plate 1 to move downward, so that the two vacuum suction cups 10 contact the upper end surface of the box a, and then the two vacuum suction cups 10 work to adsorb the upper end surface of the box a. At this time, the bottom of the entire box a is supported by the shovel plate 19, and the top is adsorbed and fixed by the two vacuum suction cups 10. In this way, when the suspension equipment suspends the device and the box a from the ground, the entire box a can remain stable.

[0045] When the two shovel plates 19 are inserted into the bottom of the box a, in order to reduce the damage of the shovel plates 19 to the box a, the present embodiment also has several rollers 20 distributed on the inclined surface of the shovel plates 19. All rollers 20 are partially embedded in the shovel plates 19 and rotatably connected thereto. When the inclined surface of the shovel plates 19 contacts the box a, the rollers 20 can convert the sliding friction between the two into rolling friction, thereby reducing the friction between the two.
