Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of storage equipment, in particular to a novel material storage rack device. Background Art
[0002] A material storage rack is a device for storing components. With the development of technology, the functions of material storage racks have also been improved, but due to the limitations of their own structure, they still have the following technical shortcomings. Specifically, when items with a certain shape (such as components packaged in packaging boxes) are stacked from top to bottom in their internal warehouse, the placement of the material storage rack itself is unstable and tilts forward, or when the height of the multi-layer stacked items is relatively high and the stacking is not neat, when the staff opens the warehouse door, there is a probability that the items will tip out of the warehouse, thereby causing damage to the corresponding items or the material storage rack. In summary, it is very necessary to provide a rack device that is mainly used for safely stacking items with a certain shape. Utility Model Content
[0003] In order to overcome the drawbacks of existing material storage racks due to structural limitations as described in the background technology, the present invention provides a new type of material storage rack device that, under the joint action of relevant mechanisms, after the staff takes out the items from the corresponding warehouse, only needs to operate a simple power switch to automatically press the lower end of the pressure plate to tighten multiple component boxes stacked from top to bottom, thereby preventing the items in the warehouse from tipping forward and being damaged as much as possible.
[0004] The technical solution adopted by the utility model to solve its technical problems is:
[0005] The cam is secured to the upper and lower ends of the cam, and the cam is secured to the lower ends of the cam, and the cam is secured to the lower ends of the cam.
[0006] Furthermore, the force-bearing surface of the pressure resistor faces the lower end, and the height of the force-bearing surface of the pressure resistor is lower than the height of the lower end of the movable plate.
[0007] Furthermore, the outer dimensions of the movable panel are smaller than the inner dimensions of the storage bin.
[0008] Furthermore, the two connection terminals of the pressure resistor of each set of control circuits are electrically connected to the signal input terminal of each set of control circuits.
[0009] Compared with the existing technology, the present invention has the following advantages: the present invention stacks items from bottom to top in the corresponding storage bins. After the power switch is turned on, the control circuit and the pressure plate mechanism automatically press the lower end of the pressure plate against the stacked multiple boxes, thereby preventing the items in the bins from tipping over and being damaged. When the corresponding item needs to be taken out, the power switch is turned back on, and the lower end of the pressure plate separates the item at the top, making it easy to take out one item. In summary, the present invention has good application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

A rectangular movable plate 33. Each storage bin 101 has an opening 104 in the middle of its rear upper end. The motor reduction device M1 is vertically distributed and bolted to the upper end of one of the storage bins 101, and the rotating shaft is located in the opening (the inner diameter of the opening is larger than the outer diameter of the rotating shaft). The upper part of the screw rod 31 is welded to the lower end of the rotating shaft. The bearing seat 32 is fixedly installed in the middle of the lower end of one of the storage bins 101 by bolts. The lower end of the screw rod 31 is tightly fitted in the inner ring of the bearing seat 32. There is a wire hole 35 that passes through the middle of the rear end of the movable plate 31. The wire hole 35 and the screw rod 31 of the movable plate are connected together by threads. The four sets of control circuits are respectively equipped with a pressure resistor RT. There is an upward concave fixing groove 34 in the middle of the lower side end of the movable plate of each set of pressure plate mechanism, and the pressure resistor RT is installed in the fixing groove 34.
[0015] Figure 1 、 2As shown in Figures 3 and 4, the pressure-bearing surface of the pressure resistor RT faces downward, and the height of the pressure-bearing surface of the pressure resistor RT is lower than the height of the lower end of the movable plate 33. The external dimensions of the movable plate 33 are slightly smaller than the internal dimensions of the storage compartment 101. Each control circuit includes resistors R1 and R2, transistor Q1, and relay J1, which are connected via circuit board wiring. The positive power input terminal of relay J1 is connected to the positive control power input terminal, the collector of transistor Q1 is connected to the negative power input terminal of relay J1, the emitter of transistor Q1 is connected to the negative control power input terminal of relay J1, and one end of the first resistor R1. The other end of the first resistor R1 is connected to one end of the second resistor R2, and the other end of the second resistor R2 is connected to the base of transistor Q1. The two connection terminals of each set of controlled pressure resistors RT are respectively connected to the positive power input terminal of relay J1 and the other end of the first resistor R1 via wires. The power input terminals 1 and 2 of the power module A1 are connected to the two poles of the AC 220V power supply via wires, respectively. The power output terminals 3 and 4 of the power module A1 are connected to the power input terminals 1 and 2 of the four sets of power switches S1 via wires, respectively. The first power output terminals 3 and 4 of each set of power switches S1 are connected to the positive and negative power input terminals of each set of motor reduction equipment M1 via wires, respectively. The second power output terminals 5 and 6 of each set of power switch S1 are connected to the positive power input terminal of the power input terminal relay J1 of each control circuit and the emitter of the transistor Q1 via wires, respectively. The two normally closed contact terminals of the power output terminal relay J1 of each control circuit are connected to the positive and negative power input terminals of the motor reduction equipment M1 via wires, respectively. Figure 3 Among them, the resistance values of resistors R1 and R2 are 4.7K and 10K respectively; the transistor Q1 model is 9013; the relay J1 model is 9013 (NPN); the pressure resistor RT is a high-precision resistance strain gauge model BF350; the motor reduction device M1 is a finished coaxial motor gear reducer with a working voltage of 24V and 30W; the power module A1 is a finished AC 220V to DC 24V switching power supply module. Figure 3 In the present invention, the electrical components are mature existing industrial products, and this application does not elaborate on their working principles.
[0016] Figure 1 、 2As shown in Figures 3 and 4, the present invention opens the movable door 102 and stacks the items from bottom to top into the corresponding storage bin 101. After the 220V AC power enters the power input of the power module A1, the output of the power module A1 outputs a 24V DC power which enters the power input of the four power switches S1. When a staff member needs to remove an item from a corresponding storage bin 101, they turn the handle of the corresponding power switch S1 to the left, connecting pins 1 and 2 and pins 3 and 4 of the handle of the power switch S1. This connects the positive and negative power inputs of the corresponding motor reduction device M1, and the motorized screw 31 of the rotating shaft rotates clockwise. The screw 31 acts on the internal thread of the thread hole 35 of the movable plate 33, causing the movable plate 33 to move upward and no longer compress the top item in the corresponding storage bin, allowing the staff member to remove the top item. After taking out the top item, or after stacking multiple item boxes from bottom to top, the staff manually turns the handle of the corresponding set of power switch S1 to the right, and the 1, 2 pins and 5, 6 pins of the power switch S1 are connected respectively. In this way, the negative and positive pole power input terminals of the corresponding set of motor reduction equipment M1 are energized, and its shaft electric screw 31 rotates counterclockwise. The screw 31 acts on the internal thread of the thread hole of the movable plate 33, and the movable plate 33 then moves downward to press the top item in the corresponding storage bin to prevent it from tipping toward the front. When the movable plate 33 is descending, when the force-bearing surface of the pressure resistor RT contacts the upper part of the uppermost item box, the resistance value of the pressure resistor RT will change. When the movable plate 33 is not in place when descending, the force on the force-bearing surface of the pressure resistor RT is relatively low and its resistance value is relatively large, the voltage divided between it and the resistor R1 is relatively large, and the 24V power supply is divided by the pressure resistor RT and the resistor R1, and the resistor R2 reduces the voltage and limits the current to enter the base of the transistor Q1 below 0.7V. The transistor Q1 will not be turned on, and the relay J1 will not be turned on. In this way, the relay J1 will not be energized and its control power input terminal and the normally closed contact terminal will continue to be closed. The power output from the 1st and 2nd pins and the 5th and 6th pins of the power switch S1 will continue to control the power input terminal and the normally closed contact terminal of the relay J1 and continue to enter the negative and positive power input terminals of the motor reduction device M1. The motor reduction device M1 continues to be energized and work, and the corresponding set of movable plates 33 continues to descend.When the movable plate 33 moves down to the right position (just pressing the topmost item), the force on the force-bearing surface of the pressure resistor RT is relatively high and its resistance value is relatively small, and the voltage divided between it and the resistor R1 is relatively small. The 24V power supply is divided by the pressure resistor RT and the resistor R1, and the resistor R2 reduces the voltage and limits the current and enters the base of the transistor Q1, which is higher than 0.7V. The transistor Q1 will turn on the collector and output a low level to the negative power input terminal of the relay J1. The relay J1 will be energized to turn on its control power input terminal and the normally closed contact terminal to open the circuit. In this way, the power output from pins 1, 2 and pins 5, 6 of the power switch S1 will no longer continue to pass through the control power input terminal and the normally closed contact terminal of the relay J1, and continue to enter the negative and positive power input terminals of the motor reducer M1. The motor reducer M1 loses power and no longer works. The corresponding set of movable plates 33 will no longer move downward to ensure that after pressing the topmost item box, it will no longer move downward to press the item box. Subsequently, when the item boxes in a corresponding storage bin are taken out and put in again and multiple item boxes need to be put in, the staff will turn the handle of the corresponding power switch S1 to the left, and the handle 1, 2 and 3, 4 of the power switch S1 will be connected respectively. The positive and negative power input terminals of the corresponding motor reduction device M1 will be energized, and its rotating shaft electric screw 31 will rotate clockwise. The screw 31 acts on the inner thread of the thread hole of the movable plate 33. The movable plate 33 will then move upward to the stop point and turn off the power switch S1. Then, after the handle of the power switch S1 is turned to the right again, the corresponding movable plate 33 will automatically press the items in the corresponding storage bin.
