DETAILED DESCRIPTION

[0022] In order to facilitate those skilled in the art to understand the present invention, the present invention will be further described in detail below in conjunction with specific embodiments and drawings.

[0023] Reference Figures 1 to 4 The utility model provides an automatic silo device, including a frame 1, a conveying mechanism 2 arranged on the frame 1, a first silo 3 arranged on the conveying mechanism 2, a second silo 4 arranged on the conveying mechanism 2, and a loading and unloading station 5 is arranged between the first silo 3 and the second silo 4.

[0024] The first silo 3 and the second silo 4 both include a silo frame disposed on the conveying mechanism, a lifting mechanism 31 disposed on the conveying mechanism 2, and a material tray 6 is stacked in the silo frame. In this embodiment, the first silo 3 is used for feeding, and the second silo 4 is used for discharging, that is, the first silo 3 is used to place the mobile phone shells to be processed, and the second silo 4 is used to place the processed mobile phone shells.

[0025] The lifting mechanism 31 includes a lifting fixed frame 311 connected to the side of the conveying mechanism 2, a first lifting cylinder 312 connected to the lifting fixed frame 311, a second lifting cylinder 313 connected to the output end of the first lifting cylinder 312, and a lifting bracket 314 connected to the output end of the second lifting cylinder 313, wherein the first lifting cylinder 312 is arranged in the horizontal direction, and the second lifting cylinder 313 is arranged in the vertical direction. Figure 1 For example, the conveying mechanism 2 conveys the material tray 6 from left to right, and two lifting mechanisms 31 are provided, which are respectively arranged on the front and rear sides of the conveying mechanism 2.

[0026] The silo frame includes two first frame assemblies 32 respectively connected to both sides of the conveying direction of the conveying mechanism 2, and two second frame assemblies 33 respectively connected to both sides of the conveying direction of the conveying mechanism 2. The two first frame assemblies 32 and the two second frame assemblies 33 enclose a space for accommodating the tray 6. The first frame assembly 32 is close to the loading and unloading station 5. The second frame assembly 33 includes a fixed bracket 331 connected to the conveying mechanism 2, a limit cylinder 332 arranged on the fixed bracket 331, and a limit stop bar 333 connected to the limit cylinder 332. The limit cylinder 332 is arranged in the horizontal direction. In the initial state, the limit stop bar 333 does not block the conveying mechanism 2 from conveying the tray 6. After the stacked trays 6 enter the first silo 3, the limit cylinder 332 extends so that the limit stop bar 333 blocks the tray 6, and the tray 6 is confined in the first silo 3.

[0027] The first frame assembly 32 includes a connecting frame 321 connected to the conveying mechanism 2, and an angle aluminum 322 arranged on the connecting frame 321. The angle aluminum 322 is provided with an opening near the bottom for the material feeding tray 6 to pass through. Since the opening is provided, the lowest material tray 6 can pass through the opening and enter the loading and unloading station 5. In addition, an optical fiber sensor is provided near the angle aluminum 322 of the first frame assembly 32 of the first material bin 3 to detect whether there are still material trays 6 in the first material bin 3. Similarly, an optical fiber sensor is also provided near the upper end of the fixed bracket 331 of the second frame assembly 33 of the second material bin 4 to sense whether the material trays 6 are fully stacked.

[0028] The conveying mechanism 2 includes a conveying frame 21, a conveyor belt 22 arranged on the conveying frame 21, and a conveying driving member 23 for driving the conveyor belt 22. The first material bin 3 and the second material bin 4 are connected to the conveying frame 21, that is, the first frame assembly 32 and the second frame assembly 33 are both connected to the conveying frame 21.

[0029] The conveying mechanism 2 is provided with an incoming material blocking assembly 7 and a tray 6 positioning assembly, the incoming material blocking assembly 7 is located on the side of the loading and unloading station 5 close to the first silo 3, and the tray 6 positioning assembly is located on the side of the loading and unloading station 5 close to the second silo 4; the incoming material blocking assembly 7 and the tray 6 positioning assembly both include a blocking bracket 81 connected to the conveying mechanism 2, a blocking cylinder 82 provided on the blocking bracket 81, and a blocking member 83 connected to the blocking cylinder 82. The incoming material blocking assembly 7 can prevent the tray 6 from flowing to the loading and unloading station 5, and the tray 6 positioning assembly can limit the tray 6 flowing into the loading and unloading station 5 to a preset loading and unloading position.

[0030] The lifting bracket 314 of the lifting mechanism 31 of the first silo 3 is evenly provided with a plurality of teeth 315 on one side facing the tray 6, and the tray 6 is provided with a groove corresponding to the teeth 315. The teeth 315 can be inserted into the groove, so as to facilitate lifting the stacked trays 6. Taking the first silo 3 as an example, the piston rod of the first lifting cylinder 312 is extended in the initial state. When the piston rod retracts, the teeth 315 are inserted into the groove of the bottom tray 6. At this time, the second lifting cylinder 313 is lifted up, and all the trays 6 above can be lifted and separated from the bottom tray 6. At this time, the bottom tray 6 can be sent to the loading and unloading station 5 by the conveyor belt 22. For the second silo 4, after the first tray 6 enters the second silo 4, the first lifting cylinder 312 and the second lifting cylinder 313 cooperate to lift the first tray 6, leaving space below for the next tray 6 to enter. After the second tray 6 enters the second silo 4, the second lifting cylinder 313 is reset, and the second lifting cylinder 313 is reset, so that the first tray 6 is stacked on the first tray 6, and the lifting bracket 314 returns to the bottom of the second tray 6, and performs the lifting action again to lift the two trays 6, and so on. In this embodiment, the width of the tray 6 is greater than the width of the conveyor belt 22, so that the lifting bracket 314 of the second silo 4 can enter the bottom of the tray 6.

[0031] The loading and unloading station 5 is provided with a material sensor 51, which is used to sense whether the material tray 6 is in place. After sensing that the material tray 6 is in place, the loading and unloading operation can continue.

[0032] The first guide plate 24 and the second guide plate 25 are respectively disposed at both ends of the conveying mechanism 2. The first guide plate 24 is disposed adjacent to the first bin 3, and the second guide plate 25 is disposed adjacent to the second bin 4. Two first guide plates 24 are symmetrically disposed, and two second guide plates 25 are symmetrically disposed. The first guide plates 24 and the second guide plates 25 can guide the material tray 6 to be centered.

[0033] The conveying mechanism 2 is provided with a controller 9 having a touch screen for setting parameters and monitoring the operation of the loading and unloading device.

[0034] During operation, the utility model can cooperate with the loading and unloading manipulator to operate, and the conveying mechanism 2 is connected with other feeding conveying devices. When the stacked trays 6 enter the first bin 3, the limit cylinder 332 of the first bin 3 drives the limit stop bar 333 to block the trays 6, and then the trays 6 are sent to the loading and unloading stations 5 one by one. The manipulator puts the mobile phone shell into the corresponding processing equipment for processing, and puts the mobile phone shell back into the tray 6 after the processing is completed. After all the mobile phone shells of the current tray 6 are processed, the current tray 6 enters the second bin 4, and the limit stop bar 333 of the second bin 4 blocks the tray 6 in the second bin 4. When all the trays 6 are transferred from the first bin 3 to the second bin 4, it means that the processing of the current batch of mobile phone shells is completed, the limit stop bar 333 of the second bin 4 is reset, and the conveyor belt 22 sends the trays 6 away. At the same time, a new batch of trays 6 enter the first bin 3, and a new round of processing continues.
