Description

Technical Field

[0001] This invention relates to the field of logistics technology, and more specifically to an intelligent conveying device for warehousing logistics. Background Technology

[0002] In modern warehousing and logistics systems, automated cargo transport is a key element in improving logistics efficiency. With the rapid development of e-commerce and intelligent manufacturing, the demands for automation and efficiency in warehousing and logistics are increasing. Intelligent conveying devices, as core equipment in warehousing and logistics systems, undertake important functions such as cargo handling, transfer, and sorting.

[0003] However, traditional conveyor systems typically only carry and transport goods in a simple manner, lacking effective limiting mechanisms. When the conveyor system starts, stops, turns, or encounters uneven ground, goods are prone to sliding, tilting, or even falling off the conveyor platform. This problem is particularly severe for irregularly shaped or smooth-surfaced goods.

[0004] Because goods are prone to shifting and collisions during transportation, not only does the efficiency of transport become affected, but damage can also occur, increasing logistics costs. This risk is particularly high for fragile, high-precision, or high-value goods, severely impacting a company's economic performance.

[0005] In addition, when the goods deviate in position during transportation, it will cause a deviation between the actual position of the goods and the preset position, affecting the accuracy of subsequent operations such as gripping, sorting, and assembly. Or the goods may tilt or flip, causing the orientation of the goods to be inconsistent with the expectation, which will affect the normal operation of automated equipment.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the Invention

[0009] Furthermore, the compression chamber has a left air outlet and a right air outlet symmetrically opened on its side wall; The left air outlet is connected to a first limiting mechanism, and the right air outlet is connected to a second limiting mechanism. The first limiting mechanism and the second limiting mechanism have the same structure.

[0010] Furthermore, the first limiting mechanism and the second limiting mechanism are arranged diagonally along the picking platform.

[0011] Furthermore, a second piston rod is fixedly connected to the bottom of the second piston; the second piston rod passes through the bottom of the compression chamber; a connecting pipe is fixedly connected to the bottom of the compression chamber, and a sliding rod is slidably installed inside the connecting pipe, the bottom of the sliding rod being fixedly connected to the top of the upper limit plate; a second reset spring that drives the upper limit plate to reset is also installed inside the connecting pipe.

[0012] Furthermore, a gap is left between the second piston rod and the sliding rod.

[0022] like Figures 1 to 10 As shown, the present invention relates to an intelligent conveying device for warehousing and logistics, comprising: a conveyor 101, which serves as the mobile carrier of the entire device, and is provided with rolling wheels 106 at the bottom, enabling it to move flexibly to a designated position.

[0023] The picking platform 102 is located on top of the conveyor 101. The picking platform 102 is equipped with forks 132, which can realize the automatic transfer of goods between the shelf and the device.

[0024] The support assembly 103 is fixedly installed on the top of the conveyor 101 and adopts a portal frame structure design. The support assembly 103 includes: uprights 129, first crossbeams 130 and second crossbeams 131; four uprights 129 are fixedly installed at the four corners of the top of the conveyor 101, and first crossbeams 130 are installed on the tops of two adjacent uprights 129 along the left-right direction of the conveyor 101, and second crossbeams 131 are installed on the tops of the two first crossbeams 130 along the front-back direction of the conveyor 101; the uprights 129, first crossbeams 130 and second crossbeams 131 together form a stable portal structure for installing the limiting assembly 104.

[0025] The limiting assembly 104 includes: a mounting base 108 fixedly installed at the top center of the second crossbeam 131; a power source 107 installed on the top of the mounting base 108; a compression chamber 109 fixedly installed at the bottom center of the second crossbeam 131, the compression chamber 109 being a hollow cylinder; an upper limit plate 110 slidably installed at the bottom of the compression chamber 109; a connecting post 119 fixedly connected to the top of the compression chamber 109, the top of the connecting post 119 being connected to the bottom of the second crossbeam 131, and the compression chamber 104 being connected to the second crossbeam 131 via the connecting post 119; The internal sliding connection of the 9 is a second piston 122; the side wall of the compression chamber 109 is symmetrically provided with a left air outlet 120 and a right air outlet 128 for outputting compressed air; the left air outlet 120 and the right air outlet 128 are located near the bottom of the compression chamber 109, the left air outlet 120 is connected to a first limiting mechanism, and the right air outlet 128 is connected to a second limiting mechanism. The first limiting mechanism and the second limiting mechanism have the same structure; and the first limiting mechanism is located on the left front side of the picking platform 102, and the second limiting mechanism is located on the right rear side of the picking platform 102. The first limiting mechanism and the second limiting mechanism are arranged diagonally.

[0026] The left air outlet 120 and the right air outlet 128 are connected in a symmetrical structure. Taking the first limiting mechanism as an example: the left air outlet 120 is connected to the air supply pipe 111, the air supply pipe 111 is connected to the first piston pipe 115, and the first piston pipe 115 is fixedly installed on the base 105; the base 105 is fixedly installed on the top of the conveyor 101 and is located on one side of the picking platform 102. The interior of the first piston tube 115 is hollow. A first return spring 113 is fixedly installed at the air inlet end of the first piston tube 115. The other end of the first return spring 113 is fixedly connected to a first piston 114. The first piston 114 is slidably installed inside the first piston tube 115. The other end of the first piston 114 is fixedly connected to a first piston rod 115. The other end of the first piston rod 115 passes through the first piston tube 115 and is connected to a side limiting plate 112. A limiting rod 118 is installed at one end of the side limiting plate 112 near the picking platform 102. The loading side and unloading side of the limiting rod 118 are respectively sloped to avoid interfering with the picking platform 102 in handling goods.

[0027] A guide post 116 is also fixedly installed inside the first piston tube 115, and a guide groove 133 is provided on the side wall of the guide post 116. As an optional approach, refer to Figure 8The guide groove 133 is composed of a straight groove and an arc-shaped guide groove 133 connected in sequence. The arc-shaped guide groove 133 covers an area of ​​85-100 degrees, preferably 90 degrees. The groove is used to limit the guide block 117 so that the side limiting plate 112 slides horizontally. The arc-shaped guide groove 133 is used to drive the side limiting plate 112 to rotate. The guide block 117 is slidably engaged with the guide groove 133. The first piston rod 115 is also fixedly mounted with a guide block 117, which is slidably connected with the guide groove 133 of the guide post 116. Through the design of the guide groove 133, the horizontal movement and rotation of the limiting rod 118 are realized. This design is suitable for handling goods of fixed size. As another alternative, refer to Figures 9 to 10 The guide groove 133 is an arc-shaped groove, and a connecting rod 134 is slidably connected to one end of the first piston rod 115 near the guide post 116. The connecting rod 134 is sleeved on the inner wall of the first piston rod 115, and the other end of the connecting rod 134 is fixedly connected to the side limiting plate 112. A guide block 117 is installed on the connecting rod 134, and the guide block 117 is slidably connected to the arc-shaped groove. A third return spring 135 is installed between the side limiting plate 112 and the first piston tube 115. The third return spring 135 is used to drive the connecting rod 134 to slide into the first piston rod 115. This makes it so that when the side limiting plate 112 contacts the goods, it can no longer move towards the goods. At this time, the side limiting plate 112 deflects along the trajectory of the arc-shaped groove, thereby causing the limiting rod 118 to deflect. This design is beneficial for adapting to goods of different sizes. The arc-shaped guide groove 133 should be configured to deflect the limiting rod 118 outward, or deflect it outward first and then inward.

[0028] The power source 107 is a cylinder or a linear motor. Taking a cylinder as an example, when the power source piston rod 121 of the power source 107 extends, it drives the second piston 122 to slide downward, compressing the air in the compression chamber 109. The air in the compression chamber 109 then flows out from the left outlet 120 and the right outlet 128 respectively. The air then passes through the air supply pipe 111 into the first piston tube 115, causing the first piston 114 to slide along the inner wall of the first piston tube 115. During the sliding process, the guide block 117 is limited by the guide post 116, first sliding horizontally and then rotating. This causes the side limiting plate 112 to first approach the goods on the picking platform 102, and then causes the limiting rod 118 to deflect, thus limiting the goods on the picking platform 102. Through the cooperation of the two side limiting plates 112 and the limiting rod 118 connected by the left air outlet 120 and the right air outlet 128, the goods can be limited to the left and right, as well as to the front and back. Specifically, the two side limiting plates 112 squeeze the goods to center them from the left and right, and the two limiting rods 118 center the goods from the front and back sides respectively, thus completing the limitation of the goods.

[0029] The bottom of the second piston 122 is also fixedly connected to the second piston rod 123; the bottom of the compression chamber 109 is also provided with a through hole, through which the second piston rod 123 passes; a connecting pipe 125 is fixedly connected to the bottom of the compression chamber 109, and a sliding rod 124 is slidably installed in the connecting pipe 125. The bottom of the sliding rod 124 is fixedly connected to the top of the upper limit plate 110; a second return spring 126 is also installed in the connecting pipe 125. One end of the second return spring 126 is connected to the upper limit plate 110 or the connecting pipe 125, and the other end is connected to the bottom of the compression chamber 109; a gap is left between the second piston rod 123 and the sliding rod 124, so that the second piston rod 123 slides down to a certain distance and then contacts the sliding rod 124, causing the sliding rod 124 to slide down, thereby limiting the goods on the picking platform 102 from top to bottom; when the second piston rod 123 slides up, the upper limit plate 110 is reset upward by the second return spring 126.

[0030] Working principle: When it is necessary to limit the goods on the picking platform 102, the power source 107 is started. The power source piston rod 121 of the power source 107 extends and pushes the second piston 122 to slide downward in the compression chamber 109, compressing the air in the compression chamber 109. The compressed air flows out from the left air outlet 120 and the right air outlet 128 at the same time, and enters the first piston tubes 115 on both sides through the air supply pipe 111.

[0031] Compressed air entering the first piston tube 115 pushes the first piston 114 to overcome the elastic force of the first return spring 113 and slide along the inner wall of the first piston tube 115, causing the first piston rod 115 to extend outward. At this time, the guide block 117 on the first piston rod 115 slides along the guide groove 133 on the guide post 116: first, it slides horizontally along the straight groove, causing the side limiting plate 112 to move horizontally towards the picking platform 102, realizing the pre-positioning of the goods in the left and right directions; when the guide block 117 enters the arc-shaped guide groove 133, it causes the side limiting plate 112 to rotate, causing the limiting rod 118 to deflect, limiting the goods in the front and rear directions.

[0032] Simultaneously, as the second piston 122 slides downward, the second piston rod 123 also moves downward. When the second piston rod 123 slides downward to contact the sliding rod 124, it pushes the sliding rod 124 to drive the upper limit plate 110 to slide downward, limiting the cargo from above and completing the vertical fixation of the cargo.

[0033] When the limit needs to be released, the power source piston rod 121 of the power source 107 retracts, and the second piston 122 returns to its original position under the action of air pressure, reducing the air pressure in the compression chamber 109. The first piston 114 returns to its original position under the action of the first return spring 113, driving the side limit plate 112 and the limit rod 118 back to their initial positions; the upper limit plate 110 returns to its original position under the action of the second return spring 126, releasing the upper and lower limits on the goods.

[0034] As can be seen from the above description, this application achieves automated limiting of goods in three dimensions: left and right, front and back, and up and down by setting the limiting component 104. This solves the problem that goods are prone to displacement due to bumps and turns in traditional conveying devices, ensuring the stability of the goods' posture during conveying and picking up / dropping, and significantly reducing the risk of goods falling and being damaged. At the same time, it can keep the goods stable during the conveying process, and when conveying the same goods multiple times, the positional consistency is good and the repeatability error is small, ensuring that the automated equipment can reliably operate the goods.
