Description

Technical Field

[0001] The utility model belongs to the field of packaging equipment, and in particular relates to a multi-layer drawer-type silo. Background Art

[0002] Cartoning machines in the packaging industry typically use a conveyor belt for loading, placing the required cartons onto the conveyor. The conveyor belt's loading capacity is small, and even at high speed, the cartoning machine can only support 7-8 minutes of normal production. This requires frequent loading by workers. Loading can also be difficult, and the loading position often doesn't always meet the cartoning machine's operating requirements. Misaligned cartons can also easily cause the cartoning machine to shut down.

[0003] In order to increase the loading capacity, it is often necessary to extend the length of the conveyor belt, which will cause the equipment to occupy a larger space. Utility Model Content

[0004] The utility model provides a multi-layer drawer-type material bin, which can store a certain number of paper boxes, meets the demand for automatic loading of material by a material-retrieving robot, and reduces the frequency of loading by personnel.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a multi-layer drawer-type silo, comprising a frame and multi-layer drawers arranged on the frame, the frame being divided into a loading area, a storage area and a retrieving area from one side to the other, the frame being provided with a linear guide rail running through the loading area, the storage area and the retrieving area, the linear guide rail being provided with multiple layers, and the multi-layer drawers sliding along the linear guide rails of the corresponding layers; locking cylinders arranged at intervals up and down are provided on the side walls of the frame located in the retrieving area, and the locking cylinders are provided on the sliding path of the drawers; positioning blocks are provided on the sides of the drawers, and positioning grooves for cooperating with the locking cylinders are provided on the positioning blocks; proximity sensors are also provided on the side walls of the frame located in the storage area and the retrieving area, and the proximity sensors are provided corresponding to the drawers of each layer for detecting the position of the drawers.

[0006] A set of slide rails is respectively provided on both sides of the drawer. The slide rails include slide rails spaced apart in an upper and lower direction and rolling bodies installed on the slide rails. The upper and lower rolling bodies respectively roll along the guide rail surfaces of the linear guide rails.

[0007] At least two rolling bodies are arranged on the slide rail.

[0008] The guide rail surface of the linear guide rail is provided with a rib or a slide groove.

[0009] The rolling element is a bearing or a roller.

[0010] The locking cylinders are distributed on the left and right sides of the frame, and the positioning blocks are arranged on the left and right sides of the drawer.

[0011] The proximity sensor is arranged on one side of the frame.

[0012] A plurality of partitions are provided in the drawer, and paper boxes are placed between adjacent partitions.

[0013] A slot is provided in the drawer, and the partition is inserted into the slot.

[0014] A button box is also provided on one side of the rack located at the loading area. The button box includes buttons and button indicator lights. The buttons and button indicator lights correspond to the number of drawers one by one. The button box is connected to the controller on the rack.

[0015] The beneficial effects achieved by the utility model are: the invention has a large capacity, reduces the frequency of personnel loading materials, and ensures the accuracy of the loading position.

[0016] Because of its drawer-style structure, a single drawer can sustain production for 7-8 minutes, compared to a horizontal conveyor belt. A multi-layer setup significantly increases carton capacity and reduces the need for personnel to load cartons. The drawer's partitions create a grid that secures the cartons' placement.

[0028] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0029] like Figure 1 As shown, a multi-layer drawer-type silo includes a frame 4 with multiple layers of storage locations arranged along the height direction. Each layer of storage location is provided with a drawer 2 that can be pulled out in both directions. Drawer 2 is used to store cartons required by a cartoning machine. The "carton" mentioned in this utility model refers to the carton sheet used to fold into a box body.

[0030] like Figure 3 As shown, the frame 4 is functionally divided into a loading area A, a storage area B, and a retrieving area C. The loading area A is located on one side of the operator 1, and the retrieving area C is located on the opposite side. A retrieving robot (not shown in the figure) is provided at the retrieving area C for retrieving materials. The storage area B is located between the loading area A and the retrieving area C, and the storage position is located within the storage area B. During use, the operator 1 pulls the drawer 2 from the storage area B to the loading area A, places the required cartons in the drawer 2, and then pushes the drawer 2 into the storage area B. When materials need to be retrieved, the retrieving robot pulls the drawer 2 out to the retrieving area C, takes out the required cartons, and then pushes the drawer 2 back into the storage area B after retrieving the materials. The bidirectional pulling and retraction of the drawer 2 ensures that the operator's loading and the retrieving robot's retrieving do not interfere with each other. Moreover, the provision of multiple drawers 2 can increase the capacity of the silo, reduce the operator's loading frequency, and meet the requirements of high-speed operation of the cartoning machine.

[0031] In order to realize the above working process, the structure of the drawer 2 is as follows Figure 4 As shown, the left and right sides of the drawer 2 are slidably mounted on linear guide rails 3 via a slide rail assembly. The linear guide rails 3 are fixed to the side walls of the frame 4. The interior of the drawer 2 is divided into partitions 10. The width between adjacent partitions 10 is consistent with the width of the paper box to ensure the correct position and posture of the paper box after it is placed, providing convenience for the material picking robot to grasp and retrieve the material.

[0032] like Figure 5 As shown, the slide rail assembly includes two slide rails 7 spaced apart in a vertical arrangement. The length of the slide rails 7 is less than the front-to-back length of the drawer 2. At least two freely rolling bearings 8 are mounted on the outer side of each slide rail 7. Rollers or other rolling elements may also be used in place of bearings. The sliding engagement between the slide rails 7 and the linear guide 3 is achieved by the bearings 8 rolling along the guide surface of the linear guide 3. Preferably, the guide surface of the linear guide 3 is provided with ribs or grooves to prevent the bearings 8 from derailing during rolling.

[0033] like Figure 1 and 7 As shown, the side wall of the frame 4 is also provided with a proximity sensor 5 for detecting the position of the drawer. The proximity sensor 5 is arranged layer by layer to detect the position of the drawer on each layer. Preferably, the storage area B and the material extraction area C are both provided with a proximity sensor 5.

[0034] Furthermore, a plurality of locking cylinders 6 are provided on the side walls of the frame of the material retrieval area C. The plurality of locking cylinders 6 are distributed on opposite sides of the frame 4 and are spaced apart up and down for locking and positioning the drawers 2 pulled out on each layer to avoid deviation of the drawer position during the material retrieval process.

[0035] Correspondingly, such as Figure 3 and 8 As shown, positioning blocks 12 are respectively provided on the left and right sides of the drawer 2, and positioning grooves are provided on the positioning blocks 12. When the drawer 2 is pulled out to the material collection area C, the piston of the locking cylinder 6 extends out and is stuck in the positioning groove of the positioning block 12 to lock the position of the drawer 2.

[0036] Preferably, Figure 1 、 2 As shown, a button box 9 is further provided on the side of the frame 4 facing the operator 1. The button box 9 is provided with buttons and button indicator lights. The buttons and button indicator lights correspond to the number of layers of the drawers 2. After the operator pushes the drawer 2 of a certain layer into the middle storage area B, he presses the button of the corresponding layer. At this time, the proximity sensor 5 corresponding to the corresponding layer detects the drawer, and the button indicator light on the button box 9 lights up, indicating that the drawer 2 of the layer has reached the correct position.

[0037] The following is a detailed description of the loading and retrieving process of this utility model. The loading and retrieving process of this device requires the cooperation of the operator and the retrieving robot. The general operation process is: the operator loads the paper box → pushes it into the intermediate storage position and presses a button → the robot grabs it → after grabbing, the robot pushes the drawer back to the intermediate storage position. The specific steps are as follows:

[0038] 1. The operator pulls out the first-layer drawer to the loading area, places the carton in the grid formed by the partition inside the drawer, and when it is full, pushes the drawer back to the middle storage area and presses the button on the button box corresponding to the first-layer drawer;

[0039] 2. The proximity sensor corresponding to the first-layer drawer detects the drawer position. After confirming that the drawer has reached the position, the controller (installed on the rack) controls the button indicator of the corresponding layer in the button box to light up;

[0040] 3. The operator repeats steps 1 and 2 above until all drawers are filled;

[0041] 4. When retrieving materials, the retrieving robot in the retrieving area pulls the drawer out to the retrieving area, and then the proximity sensor on the corresponding layer of the retrieving area detects the position of the drawer. When it detects that the drawer is pulled out to the right position, the controller controls the locking cylinder on the corresponding layer to extend and engage with the positioning blocks on both sides of the drawer to lock the drawer;

[0042] 5. After the retrieving robot finishes retrieving materials from the drawer, the locking cylinder retracts and the retrieving robot pushes the drawer back to the middle storage area.
