Description

Technical Field

[0001] The invention relates to the technical field of stackers, in particular to a straight track double-column stacker. Background Art

[0002] The double-column stacker is one of the main components of the automated warehouse. Different from the single-column stacker, the frame structure is a rectangular frame composed of two columns, an upper beam and a lower beam. It is larger in size than a single column and has good structural rigidity. However, during operation, when the cargo on the loading platform is large or the product is light, there is no fixing device, which causes the product to tilt when following the stacker. When the tilt is severe, it will cause the product to slide and injure the product or the staff below. In order to solve this problem, a straight double-column stacker is proposed. Summary of the invention

[0003] The object of the present invention is to provide a straight track double-column stacker to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a straight double-column stacker, comprising a bracket, a cargo platform is installed on the bracket, a fork is installed on the cargo platform, a lifting mechanism is installed on one side of the bracket, an electric control box is installed on the other side of the bracket, a group of first electric telescopic rods are installed on both sides of the cargo platform, and an electric lifting rod is installed on the output end of the first electric telescopic rod.

[0005] The present invention further describes that a camera system is installed at both the front and rear ends of the cargo platform.

[0006] The present invention further illustrates that an outer rod is installed at the output end of the electric lifting rod on the left side of the cargo platform, an inner rod is slidably connected inside the outer rod, and the other end of the inner rod is connected to the electric lifting rod on the right side of the cargo platform.

[0007] The present invention further describes that a groove is provided on the inner side wall of the electric lifting rod, a hydraulic rod is installed on the inner upper surface of the groove, and a second electric telescopic rod is installed on the output end of the hydraulic rod.

[0008] The present invention further describes that an infrared detector is installed on the upper end of one group of the electric lifting rods, and a baffle is installed on the upper end of another group of the electric lifting rods, and the baffle corresponds to the position of the infrared detector.

[0009] The present invention further describes that a first pressure sensor is installed on the electric lifting rod, and a second pressure sensor is installed on the outer rod.

[0010] The present invention further illustrates that the specific steps of the fixing assembly are as follows:

[0011] The first step is to set the upper pressure limit of the first pressure sensor and the second pressure sensor, and the camera system takes a picture of the taken product and sends the product to the electric control box;

[0012] In the second step, the electric control box preliminarily determines the size of the product based on the received picture, and adjusts the position of the electric lifting rod, outer rod and inner rod according to the size, so that the electric lifting rod, outer rod and inner rod do not affect the product being moved to the cargo platform, so as to adapt to different sizes;

[0013] In the third step, after the product is moved to the loading platform, the electronic control box controls the electric lifting rod to move towards the product at the same time until the pressure between the first pressure sensor and the product is greater than the upper limit of pressure, thereby fixing the product in the middle of the loading platform. At the same time, the electric lifting rod drives the outer rod and the inner rod to move downward, so that the pressure between the second pressure sensor and the product is greater than the upper limit of pressure, thereby achieving the effect of using the outer rod and the inner rod to fix the top of the product.

[0014] The present invention further illustrates that the specific steps of the fine-tuning component are as follows:

[0015] In the first step, after the product is fixed, the infrared detector sends the echo data of the upper surface of the product to the electric control box, and the electric control box sets this as the original data of the product;

[0016] In the second step, when the product is moved to the desired placement, the infrared detector detects the upper surface of the product in real time and sends the echo data to the electric control box;

[0017] In the third step, if the data changes, the electric control box determines the tilt position of the product based on the original data and the changed data of the product, and controls the second electric telescopic rod at the corresponding position to extend into the bottom of the product. At the same time, the hydraulic rod is opened to make the hydraulic rod drive the second electric telescopic rod to slightly lift the tilted product until the data sent by the infrared detector is the same as the original data of the product, thereby achieving the effect of correcting the product.

[0018] Compared with the prior art, the beneficial effect achieved by the present invention is as follows: the present invention adopts a first electric telescopic rod and an electric lifting rod, and the electric control box controls the first electric telescopic rod to retract synchronously at the same time, and the electric lifting rods on both sides are simultaneously approached to gradually fit the products on the cargo platform, and push the products on the cargo platform to the middle of the cargo platform until the pressure value of the first pressure sensor is higher than the preset pressure upper limit value, thereby fixing the product and moving the product to the center position on the cargo platform at the same time, so that the cargo platform is evenly stressed, and the tilting of the cargo platform caused by uneven force can be prevented, which causes the product to slide down.

DETAILED DESCRIPTION

[0024] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figure 1 The present invention provides a technical solution: a straight double-column stacker, comprising a bracket 1, a cargo platform 4 is slidably connected to the side wall of the bracket 1, a lifting mechanism 3 is installed on one side of the bracket 1, the lifting mechanism 3 is controlled by a servo mechanism, the output end of the lifting mechanism 3 is fixedly connected to the cargo platform 4, the lifting mechanism 3 is used to control the lifting and lowering of the cargo platform 4, the bracket 1 is used to support the cargo platform 4, and an electric control box 2 is installed on the other side wall of the bracket 1, and the electric control box 2 is used to receive signals, process data, and send instructions.

[0026] See also Figure 2 A group of forks 5 are installed on the upper surface of the cargo platform 4. The group of forks 5 is driven by a driving device and controlled by an electric control box 2 for picking up products. First electric telescopic rods 6 are installed on the front and rear ends of both sides of the cargo platform 4 for adjusting the position of the products on the cargo platform 4. The output ends of the first electric telescopic rods 6 are fixedly connected with electric lifting rods 7. The output ends of the two electric lifting rods 7 on the left are fixedly connected with outer rods 10, and the output ends of the two electric lifting rods 7 on the right are fixedly connected with inner rods 11. The other end of the inner rod 11 is slidably connected to the inside of the outer rod 10. The electric lifting rod 7 is used to drive the outer rod 10 and the inner rod 11 to move up and down, so as to achieve the effect of fixing the products from above.

[0027] See also Figure 2A row of infrared detectors 12 are installed at the upper ends of the two electric lifting rods 7 on the left. The infrared detectors 12 are flush with the lower surface of the outer rod 10 and are used to emit infrared light and receive infrared echoes, so as to judge the inclination of the upper surface of the product. A row of baffles 13 are installed at the upper ends of the two electric lifting rods 7 on the right. The baffles 13 correspond to the positions of the infrared detectors 12 and are used to block the infrared light that is not blocked by the product. Blocking the unblocked infrared light makes the data obtained by the infrared detector 12 faster and more accurate.

[0028] See also Figure 2-3 A groove 14 is provided on the inner surface of the lower end of the first electric telescopic rod 6, and a hydraulic rod 8 is fixedly installed on the upper surface of the groove 14. The output end of the hydraulic rod 8 is fixedly connected to the second electric telescopic rod 9. The output end of the second electric telescopic rod 9 faces the cargo platform 4. The lower surface of the second electric telescopic rod 9 is located above the upper surface of the cargo platform 4. The second electric telescopic rod 9 is used to extend into the bottom of the product on the cargo platform 4 when the product on the cargo platform 4 is tilted. The hydraulic rod 8 is used to drive the second electric telescopic rod 9 to lift up and adjust the flatness of the product on the cargo platform 4.

[0029] See also Figure 2 A camera system 15 is installed on both the front and rear sides of the cargo platform 4 for photographing the product to determine the specific size of the product. A first pressure sensor 16 is installed on the inner wall of the electric lifting rod 7 for determining the fit between the electric lifting rod 7 and the product. A second pressure sensor 17 is installed on the lower surface of the outer rod 10 for determining the fit between the outer rod 10 and the product.

[0030] The lifting mechanism 3 , the fork 5 , the first electric telescopic rod 6 , the electric lifting rod 7 , the hydraulic rod 8 , the second electric telescopic rod 9 , the infrared detector 12 , the camera system 15 , the first pressure sensor 16 , and the second pressure sensor 17 are all connected to the electric control box 2 by signals.

[0031] Working principle: the electric control box 2 controls the lifting mechanism 3 so that the lifting mechanism 3 drives the cargo platform 4 to rise to the position where the product is required to be picked up. After the cargo platform 4 reaches the designated position, the electric control box 2 controls the photographing system 15 to take a photo of the product to be picked up. The photographing system 15 transmits the taken photo to the electric control box 2. The electric control box 2 calculates the specific size of the product according to the size in the photo, and controls the first electric telescopic rod 6 to move outward according to the size, so that the electric lifting rod 7 is located on the outside of the product. At the same time, the electric control box 2 controls the opening of the electric lifting rod 7, so that the electric lifting rod 7 lifts the outer rod 10 and the inner rod 11 upward to prevent the outer rod 10 and the inner rod 11 from being blocked from moving the product to the upper center of the cargo platform 4 due to the close distance between the outer rod 10 and the inner rod 11 and the cargo platform 4. At the same time, the fork 5 is also controlled to start by the electric control box 2. The started fork 5 takes out the product and moves it to the upper center of the cargo platform 4.

[0032] Before using the stacker, first set the upper pressure limits of the first pressure sensor 16 and the second pressure sensor 17 on the electrical control box 2. When the product is placed on the cargo platform 4, the electrical control box 2 controls the first electric telescopic rod 6 to retract synchronously, so that the first electric telescopic rod 6 drives the electric lifting rod 7 to move closer to the middle of the cargo platform 4. The electric lifting rods 7 on both sides gradually fit the products on the cargo platform 4 and push the products on the cargo platform 4 to the middle of the cargo platform 4 until the pressure value of the first pressure sensor 16 is higher than the preset upper pressure limit. The electrical control box 2 controls the first electric telescopic rod 6 to stop extending and retracting, thereby fixing the product and moving the product to the center position on the cargo platform 4, so that the cargo platform 4 is evenly stressed, thereby preventing the cargo platform 4 from tilting due to uneven stress, which may cause the product to slide down.

[0033] At the same time, the electric lifting rod 7 drives the outer rod 10 and the inner rod 11 to descend simultaneously, so that the outer rod 10 and the inner rod 11 gradually approach the upper surface of the product until the pressure value of the second pressure sensor 17 is greater than the preset pressure upper limit value. The electrical control box 2 controls the electric lifting rod 7 to stop lifting and fixing the taken out product to prevent the product from falling and causing harm to the staff under the stacker.

[0034] At this time, the infrared detector 12 sends the reflected echo data of the upper surface of the product on the cargo platform 4 to the electric control box 2, and sets this as the original data of the product. At this time, the taken product can be placed in the required position, but in this process, the infrared detector 12 detects the flatness of the upper surface of the product on the cargo platform 4 in real time, and sends the echo data received by the infrared detector 12 to the electric control box 2. If the echo data of the infrared detector 12 changes with the original data of the product, it means that the product is tilted. The electric control box 2 controls its corresponding second electric telescopic rod 9 to extend into the bottom of the product according to the tilted position of the finished product, and its corresponding hydraulic rod 8 drives the second electric telescopic rod 9 to lift slightly until the data detected by the infrared detector 12 is the same as the original data of the product, which means that the product has been corrected. At this time, the electric control box 2 controls the hydraulic rod 8 to stop extending and retracting to prevent the product from slipping due to tilting.
