Description

Technical Field

[0001] The present invention relates to the technical field of stacking, and particularly relates to a stacking process for rapid code change. Background Art

[0002] In the stacking process of sheet-shaped products, stacking blades are essential. The principle of the existing blade product stacking process is to use a circulating chain or a synchronous belt. The chain or the synchronous belt is evenly filled with blades at equal intervals, and all the blades move intermittently following the chain or the synchronous belt. The product feeding mechanism loads the products into the gaps between the blades, and then the products move following the blades. When the products reach the outlet position, the product pushing mechanism and the product outlet mechanism move at the same speed as the blades to push the products away from the blades, completing the stacking action.

[0003] The above-mentioned existing product stacking process requires a very large number of blades to be installed, and it requires the product pushing mechanism and the product outlet to follow the movement of the blades. The mechanisms used are relatively complex. When the product thickness changes and the blades need to be replaced, the workload of blade replacement is very large. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a stacking process for rapid code change, which can greatly reduce the workload of code change, achieve rapid code change, and ensure the stacking efficiency.

[0005] The purpose of the present invention is achieved by adopting the following technical solutions: A stacking process for rapid code change, the stacking process is realized based on two annular transmission components. The two ends of the two annular transmission components are coaxially installed, and the two annular transmission components are independently driven by two motors respectively. Two blade discs are installed on each annular transmission component, and a plurality of blades arranged at intervals are fixed on each blade disc. The blade discs of the two annular transmission components are arranged alternately; The stacking process includes a feeding process and a discharging and resetting process, and the feeding process and the discharging and resetting process are parallel processes that cycle according to the same operation cycle. When a running cycle starts, one blade disc of one annular transmission component just moves to the feeding station, thus entering the feeding process, and the other annular transmission component enters the discharging process. When a running cycle ends and the next running cycle starts, the two annular transmission components exchange processes; The feeding process includes: Controlling the annular transmission component entering the feeding process through a motor to make it perform an intermittent movement of alternating between stopping and moving forward in a cyclic manner, and loading the products into the blade disc at the feeding station by the product feeding mechanism during the stopping period of the annular transmission component; The discharging and resetting process includes: Controlling the annular transmission component entering the discharging and resetting process through a motor to make it sequentially go through the following four stages: In the first stage, the ring drive assembly moves forward to move the blade disc with products to the discharging station. In the second stage, the ring drive assembly pauses, and the product pushing mechanism pushes the products on the blade disc to the product outlet during the pause of the ring drive assembly. In the third stage, the ring drive assembly moves forward to move the blade disc of the ring drive assembly to the rear end of the blade disc of another ring drive assembly. In the fourth stage, the ring drive assembly moves synchronously with another ring drive assembly until a blade disc of the ring drive assembly reaches the feeding station.

[0006] Furthermore, in the feeding process, the ring drive assembly pauses for a time of L1 each time, moves forward for a time of L2 each time, and the pause and forward movement of the ring drive assembly alternate and cycle N times. The operating cycle is T, and T = N×(L1 + L2).

[0007] Furthermore, in the discharging and resetting process, the first stage takes a time of T1, the second stage takes a time of T2, the third stage takes a time of T3, and the fourth stage takes a time of T4; where T = T1 + T2 + T3 + T4.

[0008] Furthermore, the operating cycle is T = 5s; L1 = 0.2s, L2 = 0.05s, N = 20; T1 = 1s, T2 = 2s, T3 = 1s, T4 = 1s.

[0009] Furthermore, the ring drive assembly adopts a chain or a synchronous belt.

[0010] Furthermore, the blades on the blade disc are arranged along the axial direction of the ring drive assembly.

[0011] Furthermore, the blades on the blade disc are arranged at equal intervals.

[0012] Furthermore, the two blade discs of the same ring drive assembly are installed on the ring drive assembly in a centrosymmetric manner.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: The stacking process provided by the present invention is realized based on two ring drive assemblies. Since these two ring drive assemblies are independently driven by two motors respectively, they can drive the respective blade discs to perform different actions. Coupled with the fact that the blade discs of these two ring drive assemblies are arranged alternately, the two ring drive assemblies can alternately perform the feeding process and the discharging and resetting process. Furthermore, the feeding process and the discharging and resetting process can be carried out simultaneously without interference. Therefore, the blade disc that is discharging does not need to move synchronously with the blade disc that is feeding. So the blade disc that is discharging can be stationary, making it unnecessary for the product pushing mechanism and the product outlet, etc. to move along with the blades. When the product specifications change, only four blade discs need to be replaced, greatly reducing the workload of code replacement. In addition, since the feeding process will not be interrupted by factors such as product discharging and operation cycle alternation and can continue continuously, the stacking efficiency can be guaranteed.

Detailed Embodiments

[0015] Next, in combination with the drawings and specific embodiments, the present invention will be further described. It should be noted that on the premise of non-conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0016] Refer to Figures 1-7 , the embodiment of the present invention provides a stacking process for rapid code replacement. The stacking process of the embodiment of the present invention is realized based on two annular drive assemblies. The two annular drive assemblies specifically refer to Figure 1 the annular drive assembly A and the annular drive assembly B shown in Figure 1As shown, the annular drive assembly A has disk A1 and disk A2, and the annular drive assembly B has disk B1 and disk B2. A plurality of blades arranged at intervals are fixed on each disk. Generally speaking, the blades on the disk are arranged at equal intervals, and the gaps between the blades can be used to load products. The disks of the two annular drive assemblies are arranged alternately; here it means that the two annular drive assemblies are used to drive their respective disks to move along the same circular path, and the disks of the two annular drive assemblies are arranged alternately along this circular path; for example, along this circular path, disk A1, disk B1, disk A2, and disk B2 are arranged in sequence.

[0017] Specifically, the annular drive assembly can adopt a chain or a synchronous belt; the blades on the disk are arranged along the axial direction of the annular drive assembly. Here, the axial direction of the annular drive assembly refers to the direction of its rotation center line. For example, if the annular drive assembly adopts a drive chain or a synchronous belt, the two ends of the annular drive assembly need to be meshed with a sprocket or a pulley, and the axial direction of the annular drive assembly is equivalent to the axial direction of the sprocket or the pulley.

[0018] In order to facilitate the design of the operating cycle of the annular drive assembly, in the embodiment of the present invention, the two disks of the same annular drive assembly are installed on the annular drive assembly in a centrosymmetric manner; for example, disk A1 and disk A2 are centrosymmetric on the annular drive assembly A, and disk B1 and disk B2 are centrosymmetric on the annular drive assembly B.

[0019] Reference Figure 7 , the stacking process of the embodiment of the present invention includes a feeding process and a discharging and resetting process, and the feeding process and the discharging and resetting process are parallel processes that cycle according to the same operating cycle. When a running cycle starts, one disk of one annular drive assembly just moves to the feeding station, thus entering the feeding process, and the other annular drive assembly enters the discharging process. When a running cycle ends and the next running cycle starts, the two annular drive assemblies exchange processes. In the embodiment of the present invention, the feeding station refers to the position on the annular drive assembly where the product feeding mechanism C can load products; the discharging station refers to the position on the annular drive assembly where the product pushing mechanism D can push out products.

[0020] The feeding process includes: Controlling the annular drive assembly entering the feeding process by a motor to make it perform an intermittent movement of alternating stopping and forward movement in a cyclic manner, and the product feeding mechanism loads products onto the disk at the feeding station during the stopping period of the annular drive assembly.

[0021] The discharging and resetting process includes: Controlling the annular drive assembly entering the discharging and resetting process by a motor to make it go through the following four stages in sequence: In the first stage, the ring drive assembly moves forward to move the blade disc with the product to the discharging station. In the second stage, the ring drive assembly pauses. During the pause of the ring drive assembly, the product pushing mechanism pushes the product on the blade disc to the product outlet. In the third stage, the ring drive assembly moves forward to move the blade disc of the ring drive assembly to the rear end of the blade disc of another ring drive assembly. Here, the front end of the blade disc refers to the end corresponding to the forward direction of the blade disc, and the rear end of the blade disc refers to the end opposite to the forward direction. In the fourth stage, the ring drive assembly and another ring drive assembly move synchronously until a blade disc of the ring drive assembly reaches the feeding station.

[0022] In the said feeding process, the ring drive assembly pauses for L1 seconds each time, moves forward for L2 seconds each time, and the pause and forward movement of the ring drive assembly alternate in a cycle of N times. The operating cycle is T, then T = N×(L1 + L2).

[0023] In the said discharging and resetting process, the first stage takes T1 seconds, the second stage takes T2 seconds, the third stage takes T3 seconds, and the fourth stage takes T4 seconds. Among them, T = T1 + T2 + T3 + T4.

[0024] Specifically, the operating cycle can be T = 5s; L1 = 0.2s, L2 = 0.05s, N = 20; T1 = 1s, T2 = 2s, T3 = 1s, T4 = 1s.

[0025] For example, when at the starting point of an operating cycle, the blade disc A1 of the ring drive assembly A just moves to the feeding station, while the blade disc B1 of the ring drive assembly B is already filled with products and is ready to move to the discharging station. In this operating cycle, the motor M1 drives the ring drive assembly A according to the Figure 5 shown operating curve, so that the ring drive assembly A pauses - moves forward alternately for 20 times. The product feeding mechanism C will load products into the blade disc A1 when the ring drive assembly A pauses. In this operating cycle, the motor M2 drives the ring drive assembly B according to the Figure 5 shown operating curve. First, the ring drive assembly B moves forward quickly for 1s to make the blade disc B1 reach the discharging station. Then the ring drive assembly B pauses for 2s. During the pause, the product pushing mechanism D pushes the product on the blade disc B1 to the product outlet E (refer to Figure 2 ). Then the ring drive assembly B moves forward quickly for 1s again to make the blade discs B1 and B2 reach the rear ends of the blade discs A1 and A2 respectively. Finally, the ring drive assembly B moves synchronously with the ring drive assembly A for 1s (refer to Figure 3 and Figure 4). When the operation cycle ends and the next operation cycle begins, the impeller disk B2 starts to receive products, the annular transmission assembly B enters the feeding process, and the annular transmission assembly A enters the discharging process, that is, the processes of the two are interchanged. Further, referring to Figure 6 the motor operation curve shown, it can be seen that the waveforms of the operation curves of the motors M1 and M2 are the same but the phases are just staggered by 5 s.

[0026] The stacking process provided by the embodiment of the present invention is realized based on two annular transmission assemblies. Since these two annular transmission assemblies are independently driven by two motors respectively, they can drive their respective impeller disks to perform different actions. Coupled with the fact that the impeller disks of these two annular transmission assemblies are arranged alternately, the two annular transmission assemblies can alternately perform the feeding process and the discharging and resetting process, so that the feeding process and the discharging and resetting process can be carried out simultaneously without interference. Therefore, the impeller disk that is discharging does not need to move synchronously with the impeller disk that is feeding, so the impeller disk that is discharging can be stationary, making the product pushing mechanism and the product outlet, etc. do not need to move along with the blades.

[0027] When the product specification changes, only four impeller disks need to be replaced, greatly reducing the workload of code change; in addition, since the feeding process will not be interrupted by factors such as product discharging and operation cycle replacement and can continue continuously, the stacking efficiency can be guaranteed.

[0028] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
