[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The application scenarios of the present invention may be manufacturing plants and assembly lines of different production workshops.

[0030] The present invention is mainly used for products on the diversion and filtration assembly line, and also has the ability to control the assembly line. Users can use the device to divert and filter products in a single channel on the main assembly line to the remaining channels of the assembly line, which can play the role of product classification and facilitate subsequent parallel processing of products, thereby speeding up production efficiency.

[0031] Embodiments of the present invention are combined Figures 1 to 4 , provides the following technical solutions: a multi-channel multi-stage diversion filtering assembly line device, comprising: a plurality of dual-channel two-stage diversion filtering assembly line devices, wherein the dual-channel two-stage diversion filtering assembly line device is a basic device of the device of the present invention, which can divert different categories of products on the main assembly line to two tail assembly lines; according to the actual production needs of the factory, the tail assembly line can be regarded as a basic device for continuing to splice the main assembly line, and expanded to any number of channels and corresponding numbers of stages to improve processing efficiency.

[0032] In the embodiment of the present invention, it should be understood that the number of channels represents the number of categories of products after diversion and filtering; the number of levels represents the maximum number of levels in the device, that is, the maximum transmission path depth from the main pipeline to the terminal channel; the larger the number of levels, the more times the product will be diverted on average.

[0033] For example, in order to construct an n-channel m-stage filtration and diversion pipeline device, the required number of basic devices is calculated as follows:

[0034]

[0035] Here, k represents the number of base units required and n represents the number of channels.

[0036] Furthermore, the formula for the range of levels of the multi-channel multi-stage filtration and diversion pipeline device is as follows:

[0037]

[0038]

[0039] Among them, m represents the number of levels and n represents the number of channels.

[0040] In this embodiment, the dual-channel two-stage flow-dividing filtering assembly line device 10, 20, 30 is the basic part of the device of the present invention. The dual-channel two-stage flow-dividing filtering assembly line device 10 can divert different categories of products on one channel to two different channels, which is convenient for subsequent processing. If different categories of products on one channel are to be diverted to four different channels, only two identical dual-channel two-stage flow-dividing filtering devices 20, 30 need to be added to achieve the one-to-two or two-to-four functions.

[0041] Exemplarily, the device includes: a main pipeline 13, a buffer pipeline 11, a tail pipeline 12, a buffer pipeline 21, a tail pipeline 22, a buffer pipeline 30, and a tail pipeline 31. The buffer pipeline 11 and the tail pipeline 12 are responsible for shunting and filtering the single-channel product of the main pipeline 13 into dual channels of A and B, the buffer pipeline 21 and the tail pipeline 22 are responsible for shunting and filtering the products of channel A into dual channels of A1 and A2, and the buffer pipeline 31 and the tail pipeline 32 are responsible for shunting and filtering the products of channel B into dual channels of B1 and B2. In this way, the single-channel product of the main pipeline is shunted and filtered into four-channel products of A1, A2, B1, and B2. Through the above approach, the dual-channel two-stage shunting and filtering pipeline device can be expanded to a multi-channel and multi-stage shunting and filtering pipeline device, and the user can splice the device of the present invention according to the actual production needs of the factory to achieve the function of shunting and filtering multiple products.

[0042] In this embodiment, combined with Figure 2 As shown, it is a mechanical structure diagram of a dual-channel two-stage diversion filtering assembly line device provided in an embodiment of the present invention. The dual-channel two-stage diversion filtering structure includes: a correction device 14, a counting device 16 and a diversion device 15.

[0043] Exemplarily, the correction device 14 can be of different structures. The correction device example in the figure is a force feedback push rod, which adjusts the product to a suitable position without damaging the product; the counting device 16 is composed of a plurality of photoelectric gates, which is used to count the products on the assembly line and control the diversion device 15 based on this; the diversion device 15 is also adapted to different structures. The diversion device 15 example in the figure is a push rod diversion. When it is detected that the product passes through the push rod and meets the diversion conditions, the diversion device 15 is started to divert the product to other channels. The assembly line shown in the figure includes the main assembly line 13, the buffer assembly line 11 and the tail assembly line 12. The main purpose is to reduce the negative impact of the diversion process on the main assembly line through a multi-stage conveyor belt. Among them, the main pipeline 13 is used to transport products that need to be diverted, and a correction device 14 is arranged at its front end; the buffer pipeline 11 is used as a diversion site to filter and divert the products. Different pipeline speeds can be set to ensure that the diversion can proceed smoothly without affecting the main pipeline speed; a photoelectric gate 161 is arranged at the front end of the pipeline, and a diversion device 15 is arranged at the end; the tail pipeline 12 is the product pipeline after diversion, which consists of two channels to ensure that the products after diversion will not be mixed again; photoelectric gates 162, 163 and 164, 165 are arranged at the front and end of the tail pipeline 12 respectively. The product is transported to the buffer pipeline 11 via the main pipeline 13, and will be diverted and filtered to different channels of the tail pipeline 12 on the buffer pipeline 11, and subsequent product processing will also be carried out on the tail pipeline 12. The running speed of the main pipeline 13 will not be affected in the entire diversion and filtration process.

[0044] In this embodiment, combined Figure 3 As shown, it is a forward operation flow chart of a dual-channel two-stage shunt filtration pipeline device provided by an embodiment of the present invention. The forward process of the shunt filtration product of the present invention at least includes the following steps:

[0045] Step S1: The correction device corrects the posture of the product on the main waterline;

[0046] Exemplarily, the posture correction process further includes: the correction device can have a variety of design methods, such as pneumatic correction, vibration correction, force feedback push rod correction, etc.; in this engineering example, the correction device adopts a force feedback push rod correction method, through the push rod with force feedback, the product is pushed from the assembly line to the middle position without damaging the product, so as to achieve correction;

[0047] Further detect the product posture, start the correction device, and correct the product to the appropriate position;

[0048] Finally, select the appropriate correction device according to the specific production environment.

[0049] Step S2: The products of the main assembly line are transported to the buffer assembly line;

[0050] Step S3: Counting the products on the buffer line when they pass through the photoelectric gate 161 of the diverter device and controlling the diverter device to start;

[0051] Exemplarily, the counting and control process further includes: when the photoelectric gate 161 detects that a product has passed, the total number of products is counted plus one; and the diversion device is started according to the diversion conditions, for example, the diversion operation can be performed at intervals of one product.

[0052] Step S4: The diversion device diverts part of the products to other production lines;

[0053] Exemplarily, the diversion process further includes: the diversion device can be designed in a variety of ways, such as turntable diversion, roller diversion, push rod diversion, etc. In this embodiment, the diversion device adopts a push rod diversion method, and the push rod is used to push the product from the production line to different channels, thereby realizing diversion;

[0054] Further select a suitable diversion device according to the specific production environment;

[0055] When the diversion conditions are met, the product is diverted to other channels.

[0056] Step S5: Counting and performing corresponding control operations when the products on the buffer line pass through the front-end photoelectric gates 162 and 163 of the tail line;

[0057] Exemplarily, the process of counting and performing corresponding control operations further includes:

[0058] When the photoelectric gate 162 detects a product passing through, the product count of this channel is increased by one;

[0059] When the photoelectric gate 163 detects a product passing through, the product count of this channel is increased by one;

[0060] In product storage mode, control the start and stop of the tail conveyor belt.

[0061] In this embodiment, the start and stop of the diverter device in step S4 is controlled by the five photoelectric gates. When it is detected that the product passes through the diverter device, if the diverter condition is met, the diverter device will be started to divert the product to the corresponding channel. The specific control process is as follows:

[0062] For example, the channel where the photoelectric gate 162 is located is recorded as channel A, and the channel where the photoelectric gate 163 is located is recorded as channel B. When the product passes through the photoelectric gate 161 and meets the diversion condition, the counting device starts the diversion device to divert the product to channel B. If the counting device on channel B detects that this channel cannot accommodate more products, the specific capacity upper limit is set by the user. In this case, the counting device will not start the diversion device to avoid blocking of channel B due to diversion.

[0063] Specifically, when the photoelectric gate at the end of the tail assembly line is blocked by the product for too long, the upper limit of the blocking time is set by the user, and the counting device will also determine that this channel is blocked, and will not exit the blocking mode until the product at the photoelectric gate at the end is transported away. The above is just a simple control diversion method. Users can design more complex and reliable diversion conditions according to actual conditions, and pay attention to ensuring that there will be no channel conflicts and other problems during the diversion process.

[0064] Furthermore, considering the complexity of the actual production environment, when the production line starts to get blocked, in order to buy more time to solve the blockage, the device of the present invention designs a feedback control solution. When the counting device detects that there are too many products on the line, the buffer line and the tail line will enter the product storage mode, and in more serious cases, the main conveyor belt will be stopped to buy sufficient time to solve the blockage. Figure 2 Taking the dual-channel two-stage shunt filtering pipeline device shown as an example, assuming that the channel where the photoelectric gate 162 is located is blocked, for the sake of convenience of explanation, the channel where the photoelectric gate 162 is located is recorded as channel A, and the channel where the photoelectric gate 163 is located is recorded as channel B.

[0065] In this embodiment, combined Figure 4 As shown in FIG. 1 , the feedback control process of the split flow filtration product of the present invention at least includes the following steps:

[0066] Step S101: The counting device detects that channel A is blocked, and controls the tail pipeline channel A to enter the product storage mode. At this time, the tail pipeline A will stop running continuously, and will only run when and only when the photoelectric gate 162 detects the product. Once the product is transported out of the detection range of the photoelectric gate 162, the tail pipeline A will stop running immediately. Such a control program ensures that the spacing between products on the tail pipeline is minimized, so that the tail pipeline can store enough products;

[0067] Step S102: The diversion device prohibits diverting products to channel A. At this time, all products are diverted to channel B until channel B can no longer accommodate more products;

[0068] Step S103: the counting device detects that channel B is blocked, and controls the tail pipeline channel B to enter the product storage mode;

[0069] Step S104: Channel A and channel B cannot accommodate more products, and the counting device sends out an alarm signal and feedback controls the main conveyor belt to stop, reminding the operator to manually clear the blockage to avoid more serious failures.

[0070] Step S6: When the products on the tail assembly line pass through the photoelectric gates 164 and 165 at the end of the tail assembly line, they are counted and corresponding processing operations are performed.

[0071] Exemplarily, the process of counting and performing corresponding processing operations further includes:

[0072] When a product passes through the photoelectric gate 164, the total number of products and the number of products in this channel are counted down by one, indicating that the product has been diverted;

[0073] When a product passes through the photoelectric gate 165, the total number of products and the number of products in this channel are counted down by one, indicating that the product has been diverted;

[0074] Subsequent product processing is carried out on the tail conveyor.
