[0001] The utility model relates to the technical field of stack detection, in particular to a cigarette box stack type detection device. Background Art

[0002] The automated three-dimensional warehouse is the main equipment for the storage and inventory of finished cigarette box auxiliary materials. The main body of the automated three-dimensional warehouse is composed of shelves, aisle stacking cranes, inbound (outbound) workbenches, and automatic inbound (outbound) and operation control systems. The shelves are buildings or structures of steel or reinforced concrete structures. The shelves are standard-sized cargo spaces. The aisle stacking cranes travel through the aisles between the shelves to complete the storage and retrieval of goods.

[0003] Due to the high degree of automation of the equipment, it is impossible to fully monitor the working status of the stacker and the placement of the goods in real time during operation. The following phenomena may occur: the size of the stack on the loading platform exceeds the limit; the cigarette box collapses in whole or in part; the appearance of the cigarette box is abnormal, such as the cigarette box is damaged, the sealing tape of the cigarette box is not firmly attached or has an opening, which increases the troubleshooting time and affects the normal production and warehousing. Summary of the invention

[0004] To solve the above problems, the present application provides a cigarette box stack type detection device, which uses a photoelectric sensor to detect whether the stack is out of limit, and uses a camera device to collect stack images in real time to monitor the cigarette boxes. The double protection mechanism effectively ensures the normal state of the stack on the loading platform.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] The utility model provides a cigarette box stack type detection device, comprising a three-dimensional warehouse and a lane stacking crane, wherein a lane is arranged between the three-dimensional warehouses, the three-dimensional warehouse comprises a plurality of cargo platforms, the lane stacking crane transports the stack to the cargo platform, and the upper end surface and the side surface of the cargo platform are respectively installed with photoelectric sensors for detecting whether the stack on the cargo platform exceeds the limit;

[0007] The cigarette box stack type detection device also includes a camera device, which is communicatively connected to a display. A bracket is provided above the cargo platform. The camera device includes a plurality of cameras, which are mounted downward on the bracket. The cameras are used to collect stack image information and upload it to the display to monitor the stack situation in real time.

[0008] As an improvement of the above solution, the number of the cameras is two, and the two cameras are arranged directly above the cargo platform.

[0009] As an improvement of the above scheme, there are two brackets, which are installed directly above the cargo platform. A camera is installed on each bracket. Each bracket includes a vertical bar and a horizontal bar. The vertical bar is connected to the top of the cargo platform, and the horizontal bar is connected to the top of the vertical bar. The camera is installed in the middle of the horizontal bar to shoot the stacks from both sides of the cargo platform downward.

[0010] As an improvement of the above solution, photoelectric sensors are respectively provided on the upper end surface and the left and right side surfaces of the cargo platform, and two groups of photoelectric sensors are installed on each surface to form an X-shaped laser detection line.

[0011] The photoelectric sensor is connected to an audible and visual alarm. If the size of the stack on the cargo platform exceeds the limit or collapses, the cigarette box will touch the X-shaped laser detection line of the photoelectric sensor, thereby triggering the audible and visual alarm to alarm.

[0012] As an improvement of the above solution, a wireless access point is separately provided in each lane, and each wireless access point in the lane communicates with its adjacent camera device through a network.

[0013] As an improvement of the above solution, the model of the camera device is Intel RealSense D435 or Intel RealSense D455C.

[0015] The beneficial effects brought by the utility model are:

[0016] The utility model detects whether the stack exceeds the limit through the photoelectric sensor. If the size of the stack exceeds the limit or collapses, the cigarette box will block the laser detection line of the photoelectric sensor, thereby triggering the sound and light alarm. At the same time, the camera device is used to collect the image of the stack in real time, and the situation of the stack is monitored in real time through the image screen on the display. The dual protection mechanism of the photoelectric sensor and the camera device effectively ensures the normal state of the stack on the loading platform, which is conducive to the timely processing of abnormal stacks.

[0025] See also Figure 1-3 The present embodiment provides a cigarette box stack type detection device, including a stereoscopic warehouse A, a tunnel stacking crane and a camera device.

[0026] Laneways are arranged between the three-dimensional warehouses A, and the laneway stacking crane moves in the laneway to store and retrieve goods. The three-dimensional warehouse A includes a shelf, and a cargo platform 1 is arranged in the shelf. The laneway stacking crane transports the stacks to the cargo platform 1. Usually, the stacks can enter from both sides (left and right sides) of the cargo platform 1 in the laneway.

[0027] Photoelectric sensors 2 are installed on the upper end surface and the left and right side surfaces of the above-mentioned cargo platform 1, respectively, for detecting whether the height and length of the stack on the cargo platform 1 exceed the limit. Specifically, two groups of photoelectric sensors 2 are respectively arranged on each surface where the photoelectric sensors 2 are installed, and the two groups of photoelectric sensors 2 cross-emit lasers to form an X-shaped laser detection line 21. The photoelectric sensor 2 is connected to the sound and light alarm. If the stack on the cargo platform 1 exceeds the size limit or collapses, the cigarette box will block the X-shaped laser detection line 21 of the photoelectric sensor 2, thereby triggering the sound and light alarm to alert the staff to deal with the abnormal stack in time.

[0028] Above-mentioned cigarette box pile type detection device also comprises camera device, and camera device is connected with display by communication.In the prior art, because the distance around cargo platform 1 is very limited, the available space has only cargo platform 1 top and very limited height.In the present embodiment, two brackets 4 are provided above cargo platform 1, and camera device comprises two cameras 3.Two brackets 4 are installed on the top of cargo platform 1 just opposite, and a camera 3 is installed respectively on each bracket 4, and each bracket 4 comprises vertical bar 41 and cross bar 42, and vertical bar 41 is connected to the top of cargo platform 1, and cross bar 42 is connected to the top of vertical bar 41, and camera 3 is installed in the middle part of cross bar 42, and the distance from the top of pile is 1500mm, and camera 3 shoots pile downwards from both sides of cargo platform 1, so that the visual field of camera 3 can cover each exposed surface of pile, thereby can collect the image of comprehensive pile.The pile image information collected by camera 3 is uploaded to display to monitor pile situation in real time. Specifically, the camera device is mainly configured to monitor other abnormal conditions besides exceeding the size limit, that is, abnormal conditions that the photoelectric sensor 2 may not be able to detect, such as observing whether the surface of the cigarette box is damaged, whether the stack has partially collapsed, and other abnormal phenomena. By observing the stack image on the display, it can be manually determined whether there is an abnormality in the stack.

[0029] The models of the above-mentioned camera devices are Intel RealSense D435 or Intel RealSense D455C. These two depth camera devices use depth sensing technology, which can realize depth perception and 3D perception of the scene, that is, they can reconstruct the photographed stacking scene in three dimensions, and then display the three-dimensional model of the stacking on the display for the staff to monitor the situation of the stacking more intuitively and comprehensively.

[0030] In terms of the above network transmission, firstly, the cargo platform 1 can move in two directions, namely, along the direction of the lane C and the height direction of the three-dimensional warehouse A, and can communicate wirelessly, reducing the wiring cost; secondly, the metal shelves across different lanes C in the three-dimensional warehouse A seriously block the wireless signal. Figure 3In this embodiment, a wireless access point B is separately provided in each lane C, and the wireless access point B in each lane C communicates with the adjacent camera device through a network. This network configuration can improve the communication efficiency and data transmission speed between devices, and ensure the stability and accuracy of the entire cigarette box stack type detection device.

[0031] A moving device is provided below the cargo platform 1 for moving the cargo platform 1 in the three-dimensional warehouse A.
