Description

Technical Field

[0001] The utility model relates to a production material channel, in particular to a horizontal rotary buffer material channel for an automatic line. Background Art

[0002] It has become a trend for processing and manufacturing enterprises to transform to automation. Automated production lines have been widely used in many industries due to their high efficiency, labor-saving and stable product quality. Large-scale production of a single variety is one of its major features. Automated production lines can achieve less or even no production change, and pursue the maximization of automatic line processing efficiency. Therefore, existing technologies rarely have a caching mechanism to match it. However, with the development of diversified market product demand, it is sometimes necessary to process and produce multiple varieties of parts on automated production lines. In order to improve the processing flexibility of the production line, the impact of production change on the production line must be considered. Most existing production lines have complex production change process steps, which easily leads to the problem of occupying production time.

[0003] Chinese patent CN112917248A discloses a flexible processing production line for retarders, including a processing line and an automatic line. The processing line is a processing device and an auxiliary device that are arranged linearly and discontinuously from each other. The automatic line is used to transport the processed parts between the devices of the processing line. The processing line and the automatic line are parallel and independent of each other. The processing line and the automatic line of this invention are separately arranged. When a new process needs to be added to the flexible line or the production capacity needs to be expanded, only the corresponding machine tools need to be added to the processing line, while the processing line remains in its original state, which greatly reduces the cost of updating the automated flexible line. However, the shortcomings of this flexible processing production line are: complex structure and narrow application range. Utility Model Content

[0041] The operation mode of the above-mentioned automatic line with horizontal rotary buffer material channel includes the following steps:

[0042] When loading parts:

[0043] Step 1: Set the control program and load it into the automatic line control system, and the automatic line control system sends a part loading request and part information to the material channel control system;

[0044] Step 2, after the material channel control system receives the above information, the first tray detection sensor 123, the second tray detection sensor 124, the tray load detection sensor 125, the first roller tray position detection sensor 1202 and the second roller tray position detection sensor 1206 on the roller tray 1201 are first triggered, and the corresponding signals are sent to the material channel control system according to the following rules. The material channel control system controls the automatic line to execute the corresponding program with the horizontal rotary buffer material channel according to the received signals; wherein the truth table of the signal is shown in Table 1;

[0045] Table 1 Truth table of the signal

[0046]

[0047] (1) If (TPC = 1)∧(GT1 = 0), tray 2 moves along the positive direction of the X-axis to the X-direction transmission assembly 11, that is, moves from area a to area c;

[0048] (2) If (TPC = 1) ∧ (GT1 = 1), the reciprocating cylinder 121 drives the roller tray 1201 to move from area b to area a, then the value of GT1 becomes 0, and the tray 2 moves along the positive direction of the X-axis to the X-direction transmission component 11, that is, it moves from area a to area c;

[0049] (3) If (TPC = 0) ∧ (DYTP = 1) ∧ (DETP = 0) ∧ (GT1 = 0), the tray 2 moves along the positive direction of the X-axis to the X-direction transmission assembly 11, that is, moves from area a to area c;

[0050] (4) If (TPC = 0) ∧ (DYTP = 1) ∧ (DETP = 0) ∧ (GT1 = 1), first the reciprocating cylinder 121 drives the roller tray 1201 to move from area b to area a, then the value of GT1 becomes 0, and the tray 2 moves along the positive direction of the X-axis to the X-direction transmission component 11, that is, it moves from area a to area c;

[0051] (5) If (TPC=0)∧(DYTP=1)∧(DETP=1)∧(GT1=0), the material channel control system sends a request for loading to the production line, and the lifting mechanism pallet 122 moves along the positive direction of the Z axis. The lifting mechanism pallet positioning pin 1221 on it is fully limited with the pallet positioning pin hole 23. After driving the pallet 2 to the preset position, the material channel control system sends a loading preparation completion signal to the production line, and the production line manipulator starts to load the parts. After completion, the production line sends a loading completion signal to the material channel control system, and the lifting mechanism pallet 122 moves along the negative direction of the Z axis until the pallet 2 returns to the roller pallet 1201. At this time, the lifting mechanism pallet 122 continues to move down along the negative direction of the Z axis to the initial position, and then the pallet 2 moves along the positive direction of the X axis to the X-direction transmission component 11, that is, it moves from area a to area c;

[0052] (6) If (TPC = 0) ∧ (DYTP = 1) ∧ (DETP = 1) ∧ (GT1 = 1), the reciprocating cylinder 121 first drives the first roller tray 12011 to move to area a, waiting for parts to be loaded. The process is the same as rule (5). After loading is completed, the tray 2 moves along the positive direction of the X-axis to the X-direction transmission component 11, that is, it moves from area a to area c;

[0053] (7) When (TPC=0)∧(DYTP=0)∧(GT1=1) is satisfied, if CLW=1, the drive motor 111 is started to drive the tray 2 from the area d to the area b, and the tray 2 is rolled onto the first roller tray 12011. Then, the first tray detection sensor 123, the second tray detection sensor 124 and the tray load detection sensor 125 generate a trigger signal. When the signal pattern matches one of the rules (1) to (6), the corresponding program is executed. If CLW=0, wait until the tray 2 moves to the discharge position, and trigger CLW=1, and execute the subsequent actions of rule (7).

[0054] (8) When (TPC=0)∧(DYTP=0)∧(GT1=0) is satisfied, the reciprocating cylinder 121 first drives the first roller tray 12011 to move to area b, at which time GT1=1, and the action of rule (7) is executed;

[0055] Step 3, when the tray 2 moves from area a to area c, if (JLW=0)∧(ZD=0), the drive motor 111 and the roller motor on the first roller tray 12011 are started, and the tray 2 moves along the positive direction of the X-axis to the X-direction transmission component 11; if (JLW=1)∨(ZD=1), the first roller tray 12011 stops running until (JLW=0)∧(ZD=0) meets the requirement;

[0056] Step 4: Before the tray 2 moves from area e to area f, the blocking member 115 is lifted along the positive direction of the Z axis. The tray 2 is first stopped by the blocking member 115 in area d. At this time, the driving motor 111 stops running until one of the following rules is met:

[0057] a) If (DSTP=0)∧(GT2=0), the blocking member 115 descends along the negative direction of the Z axis, the driving motor 111 and the roller motor on the second roller tray 12012 are started, and the tray 2 moves from area e to area f;

[0058] b) If (DSTP=0)∧(GT2=1), the second roller tray 12012 is driven by the reciprocating cylinder 121 to first move from area g to area f. At this time (GT2=0), repeat a);

[0059] c) If (DSTP=1), wait until (DSTP=0). If (GT2=0), repeat rule a). If (GT2=1), repeat rule b).

[0060] When retrieving parts:

[0061] Step 1: Set the control program and load it into the automatic line control system, and the automatic line control system sends a part retrieval request and part information to the material channel control system;

[0062] Step 2, after the material channel control system receives the above information, the first tray detection sensor 123, the second tray detection sensor 124, the tray load detection sensor 125 and the first roller tray position detection sensor 1202 on the first roller tray 12011 are first triggered, and send corresponding signals to the material channel control system according to the following rules. The material channel control system controls the automatic line to execute the corresponding program with the horizontal rotary buffer material channel according to the received signal; wherein the truth table of the signal is shown in Table 1;

[0063] (1) If (DETP=0)∧(GT1=0), the tray 2 moves along the positive direction of the X-axis to the X-direction transmission assembly 11, that is, moves from area a to area c;

[0064] (2) If (DETP=0)∧(GT1=1), first the reciprocating cylinder 121 drives the first roller tray 12011 to move from area b to area a, then the value of GT1 becomes 0, and rule (1) is repeated;

[0065] (3) If (DETP=1)∧(TPC=0)∧(GT1=0), the tray 2 moves along the positive direction of the X-axis to the X-direction transmission assembly 11, that is, moves from area a to area c;

[0066] (4) If (DETP=1)∧(TPC=0)∧(GT1=1), first the reciprocating cylinder 121 drives the first roller tray 12011 to move from area b to area a, then the value of GT1 becomes 0, and rule (3) is repeated;

[0067] (5) If (DETP=1)∧(TPC=1)∧(GT1=0), the material channel control system sends a request for unloading to the production line, and the lifting mechanism pallet 122 moves along the positive direction of the Z axis. The lifting mechanism pallet positioning pin 1221 on it is fully limited with the pallet positioning pin hole 23. After driving the pallet 2 to the preset position, the material channel control system sends a signal of completion of unloading preparation to the production line, and the external manipulator starts to unload the parts. After the unloading is completed, the production line sends a signal of completion of unloading to the material channel control system, and the lifting mechanism pallet 122 starts to move down until the pallet 2 returns to the first roller pallet 12011. At this time, the lifting mechanism pallet 122 continues to move down until it returns to the initial position. At this time, the pallet 2 begins to prepare for lateral movement and moves to the material channel assembly 11, that is, moves from area a to area c;

[0068] (6) If (DETP=1)∧(TPC=1)∧(GT1=1), first the reciprocating cylinder 121 drives the first roller tray 12011 to move from area b to area a. At this time (GT1=0), repeat rule (5);

[0069] (7) When (DYTP=0)∧(GT1=1) is satisfied, if CLW=1, the blocking member 115 is lowered, the driving motor 111 and the roller motor on the first roller tray 12011 are started, and the tray 2 is rolled onto the first roller tray 12011. The sensor signals 123, 124 and 125 are triggered. When the signal pattern matches one of the rules (1)-(6), the corresponding program is executed; if CLW=0, wait until a tray 2 moves to the discharge position. When CLW=1, rule (7) is repeated;

[0070] (8) If (DYTP=0)∧(GT1=0), first, when the reciprocating cylinder 121 drives the first roller tray 12011 to move from area a to area b, rule (7) is repeatedly executed;

[0071] Step 3: When the tray 2 moves from area a to area c, it is the same as step 3 of “parts loading”;

[0072] Step 4: When pallet 2 moves from area e to area f, it is the same as step 4 of “parts loading”.
