Description

Technical Field

[0001] The invention relates to a medicine box packing device, in particular to a silo used in the device for storing partitions. Background Art

[0002] Generally, cartons (such as medicine boxes or other small cartons) are packed into cartons after being bundled. Currently, the bundling of cartons is completed by a carton bundling machine, and then the cartons are packed manually. In order to realize automatic cartoning, the applicant has designed a fully automatic carton packing equipment. One of the processes of the fully automatic carton packing equipment is to send partitions into the carton, which can separate multiple layers of cartons. The partitions need to be sent into the carton by a robot. As they are continuously moved, the stacked partitions will gradually decrease and the height will gradually decrease. The silo for storing the partitions needs to ensure that the top partition is always in the suction position of the robot so that the robot can suck it. There is currently no such silo for storing partitions on the market. Summary of the invention

[0021] As Figure 1 shown, this partition buffer bin includes a bin rack 1, as Figure 2As shown, the silo frame 1 is equipped with two rows of silo fence mechanisms, each row of silo fence mechanisms includes two front and rear silo fence components 2, each silo fence component 2 includes a silo fence 20 and a material dragging plate 21 installed on the silo fence 20, as shown in FIG. Figure 2 As shown, after a stack of partitions A enters the silo, it reaches the four drag plates 21 of the four silo fence assemblies 2. In order to gradually lift the placed partitions A upwards, as shown in FIG. Figure 3 or Figure 4 As shown, the present invention is provided with a partition lifting mechanism 3 between the front and rear two silo fence assemblies 2 of each row of silo fence mechanisms. Figure 5 and Figure 6 As shown, the partition lifting mechanism 3 includes a synchronous belt 30 and two synchronous wheels (the synchronous wheels are not shown in the figure), the synchronous belt 30 is wound around the synchronous wheels, and a lifting piece 31 is provided on the synchronous belt 30, and the synchronous wheels are connected to the lifting power source 33 that drives the synchronous wheels to rotate. When the partition A is placed, the lifting power source 33 drives the synchronous belt 30 to rotate, so that the lifting piece on the synchronous belt 30 lifts the partition A from the bottom. Every time the robot takes a piece, the lifting piece 31 lifts the partition A to the height of the thickness of a partition. In this way, it can be ensured that the top partition in the silo is always in the robot suction position. The partition cache silo of this structure effectively avoids the problem of personnel operation safety when the cartoner is running inside and the robot sucks the partition because the manual discharge space is designed at the bottom of the silo. At the same time, it solves the problem of time waste caused by the shutdown of the cartoner when placing the partition because the safety of the operator must be guaranteed. Therefore, configuring this partition buffer silo can significantly increase the production efficiency of the equipment and ensure the linkage reliability of the front and rear equipment and the case packing machine.

[0022] The lengths of the partitions A are different. In order to store partitions of different lengths, the present invention installs two left and right support frames 4 on the silo frame 1. Figure 3 As shown, the left row of bin fence mechanisms and the left partition lifting mechanism 3 are installed on the left support frame 4, as shown in FIG. Figure 4 As shown, the right row of silo fence mechanisms and the right partition lifting mechanism are installed on the right support frame, and the support frame 4 is installed on the silo frame 1 so as to be movable and adjustable left and right. As long as one of the support frames 1 is moved left and right (the other does not move as a reference), the support frame 1 can move the silo fence mechanism and the partition lifting mechanism 3 on this side, so that the spacing between the left and right rows of silo fence mechanisms changes, and the partition lifting mechanism 3 is also the same, thereby meeting the storage of partitions A of different lengths.

[0023] For convenient adjustment, a plurality of first pin holes 10 are provided on the bin rack 1 in the left-right direction, and a first spring pin 44 that can be inserted into the first pin holes 10 is provided on the support frame 4. After the position of the support frame 4 is adjusted, it is very convenient to adjust by simply inserting the first spring pin 44 into the first pin holes 10.

[0024] The widths of the partition plates A are different. To accommodate the storage of partition plates with different widths, a sliding shaft 41 is provided on the support frame 4, and both the bin railing assembly 2 and the partition plate lifting mechanism 3 are arranged on the sliding shaft 41 of the support frame 4 so as to be movable back and forth for adjustment. With this structure, by simultaneously moving the bin railing assembly 2 and the partition plate lifting mechanism 3 back and forth to adjust their front and rear positions, the storage of partition plates A with different lengths and widths can be satisfied.

[0025] Similarly for convenient adjustment, as Figure 3 shown, a plurality of second pin holes 43 are provided on the support frame 4 in the front-rear direction, and a second spring pin 22 that can be inserted into the second pin holes 43 is provided on the bin railing 20 of the bin railing assembly 2. After the position of the bin railing assembly 2 is adjusted, it is very convenient to adjust by simply inserting the second spring pin 22 into the second pin holes 43.

[0026] And for convenient adjustment of the partition plate lifting mechanism 3, as Figure 4 shown, a plurality of third pin holes 45 are provided on the support frame 4 in the front-rear direction, and a third spring pin 34 that can be inserted into the third pin holes 45 is provided on the partition plate lifting mechanism 3. After the position of the partition plate lifting mechanism 3 is adjusted, it is very convenient to adjust by simply inserting the third spring pin 34 into the third pin holes 45.

[0027] Since the partition plate lifting mechanism 3 needs to be driven and at the same time can be adjusted to move back and forth and left and right, as Figure 5 and Figure 6 shown, a first bevel gear 36 and a second bevel gear 37 are rotatably installed on a spline slide base 46 on the support frame 4. The first bevel gear 36 and the second bevel gear 37 are meshed. The first bevel gear 36 is sleeved on a first spline shaft 35 (spline connection), the second bevel gear 37 is connected to a second spline shaft 32 (fixed connection), the synchronous pulley of the partition plate lifting mechanism 3 is sleeved and connected to the second spline shaft 32 (spline connection), and the first spline shaft 35 is in transmission connection with the lifting power source 33. During operation, the lifting power source 33 drives the first spline shaft 35 to rotate. The first spline shaft 35 drives the second spline shaft 32 to rotate through the first bevel gear 36 and the second bevel gear 37, and the second spline shaft 32 drives the synchronous pulley of the partition plate lifting mechanism 3 to rotate, thus driving the synchronous belt 30 to rotate. As Figure 6As shown, when adjusting left and right, the first bevel gear 36 on the spline slide 46 can move left and right on the first spline shaft 35, so that the support frame 4 can achieve left and right movement adjustment, and the partition lifting mechanism 3 can also achieve left and right movement adjustment. When adjusting forward and backward, the synchronous wheel can move forward and backward on the second spline shaft 32, so that the partition lifting mechanism 3 can also achieve forward and backward movement adjustment.

[0028] like Figure 2 As shown, the silo fences 20 of the silo fence assemblies 2 on the left and right sides can be rotatably provided with guardrails 25, and the guardrails 25 are connected to the guardrail power source 26 for driving the guardrails 25 to rotate. The left and right guardrails 25 can be opened or closed by the drive of the guardrail power source 26. Figure 2 As shown, when the guardrail 25 is opened, the operator can put an extra stack of partitions into the silo from the side to replenish the partitions; after the partitions are replenished, the guardrail 25 is closed, and the guardrail 25 can act on the partition A from the side, so that the partition A in the silo can be stacked neatly to ensure that the robot arm can accurately pick up the partition and put it into the carton.

[0029] Finally, it is worth mentioning that Figure 7 As shown, the partition buffer silo is installed in the frame 6, and the frame 6 is equipped with a protective door 7, and the frame 6 or the protective door 7 is equipped with a sensor 8 that can sense the opening and closing of the protective door 7. The sensor 8 is connected to the control system, and the control system controls the guardrail power source 26 to work. When the protective door 7 is opened, the sensor 8 senses it, and the sensor 8 transmits a signal to the control system, and the control system controls the guardrail power source 26 to operate, so that the guardrail 25 automatically opens, and the operator can put an extra stack of partitions into the silo from the side; when the protective door 7 is closed, the control system controls the guardrail power source 26 to operate, and the guardrail 25 automatically closes. In this way, the convenience of manually placing partitions can be greatly improved, and the labor intensity of manual labor can be saved to the maximum extent.
