Referring to fig. 1 to 6, in an embodiment of the present utility model, a terminal packing apparatus includes:

A vibration discharger 100 for housing and outputting a terminal product;

A main bin 200 disposed corresponding to the vibration discharger 100 and receiving the output terminal product thereof, the main bin 200 including a main bin body portion 210 and a main discharge member 220 disposed to be opened and closed to the main bin body portion 210;

the main weighing device 300 is arranged corresponding to the main bin 200 and is used for obtaining the total weight of the main bin 200;

vibrating the discharge tray 400 to hold the terminal products and output the terminal products;

The auxiliary bin 500 is arranged corresponding to the vibration discharging disc 400 and receives the terminal products outputted by the vibration discharging disc, and the auxiliary bin 500 comprises an auxiliary bin main body part 510 and an auxiliary discharging part 520 which is arranged on the auxiliary bin main body part 510 in an opening and closing manner;

A controller for receiving information of the main weighing device 300 and the auxiliary weighing device 600, and controlling the operations of the vibration discharger 100, the main discharge member 220, the vibration discharge tray 400, the auxiliary discharge member 520 and the packing machine 700;

wherein, the output speed of the vibration discharger 100 is greater than the output speed of the vibration discharging tray 400.

In the prior art, the weighing mode cannot integrate the relation between the packing speed and the packing accuracy, and meanwhile, the deviation of the packing weight is larger.

In the present utility model, the vibration discharger 100 is used for housing and outputting a terminal product for conveying the terminal product therein into the main bin 200. The main bin 200 is disposed corresponding to the vibration discharger 100 and receives the terminal products outputted therefrom, and the main bin 200 is used to hold most of the terminal products (e.g., 99%) in a single package weight, so that the output speed of the vibration discharger 100 can be increased as much as possible. The main bin 200 includes a main bin body portion 210 and a main discharging member 220 provided to the main bin body portion 210 to be opened and closed, and the terminal product in the main bin body portion 210 is emptied by the main discharging member 220. The main weighing device 300 is arranged corresponding to the main bin 200, and is used for obtaining the total weight of the main bin 200 and guiding the completion of the work of the terminal packing device.

The vibratory discharge tray 400 houses terminal products that are inconsistent with the source of the terminal products in the vibratory discharge machine 100, as well as output terminal products. The terminal product in the vibratory discharge tray 400 is used only to replenish the portion (e.g., 1%) of the main bin 200 that does not meet the full package weight. The auxiliary bin 500 is arranged corresponding to the vibration discharging disc 400 and receives the output terminal products; the auxiliary bin 500 includes an auxiliary bin body portion 510 and an auxiliary discharging member 520 openly and closably provided to the auxiliary bin body portion 510. The auxiliary weighing device 600 is disposed corresponding to the auxiliary bin 500, and is used for obtaining the total weight of the auxiliary bin 500 and guiding the completion of the operation of the terminal packaging device.

Taking the main bin 200 as an example, the working modes of the main discharging part 220 can be various, and if the emptying mode of the main bin 200 is to actively utilize the gravity of the product, the main discharging part 220 can be only a flashboard type structure; if the emptying mode of the main bin 200 is passive, the main discharging member 220 needs to be correspondingly provided with a corresponding structure to convey the terminal products in the main bin 200. The output speed of the vibration discharger 100 is greater than that of the vibration discharge tray 400, so that in order to increase the packing speed of the terminal products, the discharge speed of the vibration discharger 100 should be as great as possible (a plurality of terminal products are simultaneously thrown into the main bin 200), and then the problem of inaccuracy (too much or too little) exists; the output speed of the corresponding vibration discharging tray 400 should be as low as possible (e.g., a single terminal product is thrown into the auxiliary bin 500 at the same time), and the remaining part of the packing emphasis in the main bin 200 is supplemented by the cooperation of the vibration discharging tray 400 and the auxiliary bin 500. The packing machine 700 is arranged below the main bin 200 and the auxiliary bin 500 correspondingly, and the packing machine 700 is in back sealing type or three-side sealing type; the terminal products in the main bin 200 and the auxiliary bin 500 are poured into the packing machine 700, and the packing machine 700 completes the packing work. The controller receives information of the main weighing device 300 and the auxiliary weighing device 600, and controls the operations of the vibration discharger 100, the main discharge piece 220, the vibration discharge tray 400, the auxiliary discharge piece 520, and the packing machine 700. The controller may be a PLC type or microcomputer controlled type arrangement, coordinating the operation of the various components. After the weight of the terminal products in the main bin 200 reaches the threshold value, stopping the operation of the vibration discharger 100, then filling the auxiliary bin 500 through the vibration discharge tray 400, and supplementing the residual value of the weight of the terminal products in the main bin 200 by the weight of the filled terminals; with the above arrangement, the filling speed of the main bin 200 can be increased, and the filling of the auxiliary bin 500 can be accurate, so that the whole packing process can be quickly and accurately coordinated.

In the present utility model, the vibration discharger 100 refers to a structure for discharging a terminal product stored in the vibration discharger 100 from an opening thereof by vibration in a conventional sense, and has a characteristic of high discharging speed but coarse discharging amount; the vibration discharging tray 400 refers to a structure for regularly arranging the terminal products in the material transmission channel thereof by vibration in the conventional sense and discharging the terminal products from the opening thereof more finely, and has the characteristics of low discharging speed but fine discharging amount.

In summary, the main bin 200 is filled by vibrating the discharger 100, the auxiliary bin 500 is filled by vibrating the discharge tray 400, the weight of the terminal product in the main bin 200 is monitored by the main weighing device 300, and the weight of the terminal product in the auxiliary bin 500 is monitored by the auxiliary weighing device 600; after the weight of the terminal products in the main bin 200 reaches the threshold value, stopping the operation of the vibration discharger 100, then filling the auxiliary bin 500 through the vibration discharge tray 400, and supplementing the residual value of the weight of the terminal products in the main bin 200 by the weight of the filled terminals; with the above arrangement, the filling speed of the main bin 200 can be increased, and the filling of the auxiliary bin 500 can be accurate, so that the whole packing process can be quickly and accurately coordinated.

Referring to fig. 5 to 6, in one embodiment, the bottom of the main hopper body part 210 is provided with a downward slope of 10 to 45 degrees, and the main discharge member 220 includes a main discharge plate hinged to the main hopper body part 210 in an openable manner and a main discharge driving structure 222 driving the main discharge plate to be turned over; the bottom of the auxiliary bin body portion 510 has a downward slope of 10 to 45 degrees, and the auxiliary discharging member 520 includes an auxiliary discharging plate openly and closably hinged to the auxiliary bin body portion 510 and an auxiliary discharging driving structure 522 driving the auxiliary discharging plate to be turned.

In the present embodiment, taking the main bin 200 as an example, by setting the bottom of the main bin body portion 210 to have a downward slope, the terminal products therein can escape from the main bin body portion 210 under the action of its own gravity. First, the main stripper plate is hinged to the main bin body portion 210, and is driven to open and close to the main bin body portion 210 by the main stripper driving structure 222. The driving power of the main discharge driving structure 222 may be motor, hydraulic or pneumatic, etc.

In one embodiment, the primary discharge drive structure 222 and the secondary discharge drive structure 522 are both pneumatic.

In most shop environments, a compressed air circuit is provided, in this embodiment, it is then convenient to drive pneumatically.

Referring to fig. 1 to 4, in one embodiment, a material returning tray 800 is disposed between a lower portion of the main bin 200 and an upper portion of the packing machine 700, a material returning driving structure 810 is disposed corresponding to the material returning tray 800, and the material returning driving structure 810 drives the material returning tray 800 to switch between a state of shielding and avoiding the main bin 200, wherein the material returning tray 800 has a declining tendency when the material returning tray 800 shields the main bin 200, and the controller controls the operation of the material returning driving structure 810.

In this embodiment, the tray 800 works to cope with the situation that excessive terminal products are accidentally entered in the main bin 200. Specifically, when excessive terminal products exist in the main bin 200, the controller switches from the avoiding state to the shielding state by driving the material returning disc 800, and then the controller drives the main discharging part 220 of the main bin 200 again to open the main bin 200, at this time, the terminal products in the main bin 200 are intercepted by the material returning disc 800, so that the situation that excessive terminal products are packed in a single package bag is avoided. The main discharge member 220 may be driven by a motor, pneumatic or hydraulic pressure, etc.

In one embodiment, the vibration discharger 100 is correspondingly provided with a first capacitance type material height sensor.

In this embodiment, the first capacitive feed-height sensor reflects the storage amount of the terminal product in the vibration discharger 100, and gives corresponding working guidance to the terminal packing apparatus.

Referring to fig. 1 to 4, in one embodiment, the terminal packing apparatus further includes:

a material storage hopper 910, a material outlet is arranged at the bottom of the material storage hopper 910, and the material storage hopper 910 is used for storing terminal products;

A transverse transferring member 920, disposed below the discharge port and in clearance fit with the discharge port in the height direction, where the transverse transferring member 920 is used for conveying the terminal product overflowed from the discharge port transversely;

In this embodiment, a storage hopper 910 is provided, a discharge port is provided at the bottom thereof, the storage hopper 910 is used for storing terminal products, and the terminal packing device operates to pack the terminal products in the storage hopper 910. The transverse transfer component 920 is disposed below the discharge port and forms a clearance fit with the discharge port in the height direction, and the transverse transfer component 920 is used for conveying the terminal product overflowed from the discharge port transversely. The terminal products in the storage hopper 910 overflow from the discharge port by gravity, and when the lateral transfer member 920 starts to operate, the terminal products in the storage hopper 910 continue to be transferred out for the lateral transfer member 920. The presence of the lateral transfer member 920 is due to the fact that the storage hopper 910 cannot be directly adapted to the subsequent bucket elevator 930. The bucket elevator 930 is disposed corresponding to the end of the transverse transferring member 920 in the length direction, and is configured to vertically lift the terminal product dropped from the end of the transverse transferring member 920, and an outlet of the bucket elevator 930 is disposed corresponding to the upper side of the vibration discharger 100. Because the height of the vibration discharger 100, the main bin 200, the vibration discharging tray 400 and the auxiliary bin 500 is above the packing machine 700, in order to reduce the feeding difficulty, the position of the storage hopper 910 is set lower, and then the bucket elevator 930 is required to lift the terminal product at the lower position to the height of the vibration discharger 100.
