[0008] Further, the conveying and buffering assembly has a two-section structure comprising a first section belt line driven by a first section alternating current induction motor and a second section belt line driven by a second section servo motor.

[0011] Further, the material pushing assembly comprises a material pushing platform, a push rod assembly driven by a rodless cylinder and an electromagnetic valve assembly arranged on the material pushing platform, and a material detection photoelectric sensor.

[0012] Based on the structural design of the mosquito-repellent incense piece automatic material arrangement and stacking device, the application simultaneously proposes the following mosquito-repellent incense piece automatic material arrangement and stacking method:

[0013] The mosquito-repellent incense pieces produced by the receiving machine are continuously conveyed to the receiving machine conveying line in multiple queues;

[0014] The quality of each single mosquito-repellent incense piece on the receiving machine conveying line is detected and the in-out warehouse count is counted. The unqualified mosquito-repellent incense pieces are removed from the conveying line. The qualified mosquito-repellent incense pieces are conveyed to a plurality of lamination head arrangement machines by a variable pitch conveying device.

[0015] The laminated head arrangement machine comprises a laminated head assembly and a conveying buffer assembly.

[0037] Example 1, as Figures 1 to 6 As shown, a novel automatic mosquito coil stacking and transfer assembly equipment comprises, along the production process route, this application and a transfer device consisting of a lifting receiving assembly 6, a transverse material cylinder assembly 7, a three-axis truss gripper assembly 8, and a mosquito coil stack pallet material leveling assembly 9.

[0038] The mosquito coil automatic material stacking device comprises a receiving machine conveying line 1, a same number of variable-distance conveying devices connected with the receiving machine conveying line 1 and having the same conveying channel as the receiving machine conveying line 1, a plurality of stack head alignment machines 4 connected with each variable-distance conveying device, and a material pushing assembly 5 arranged at the conveying end of each group of stack head alignment machines 4.

[0039] Specifically, the receiving machine conveying line 1 is connected with a receiving machine at the front end of mosquito coil production, and the receiving machine conveying line 1 can select various types of conveying devices, such as a roller machine, a narrow belt conveyor, and a receiving machine belt line designed as follows:

[0040] The device comprises a wire body frame 1.11, a plurality of conveying belts arranged on the top of the wire body frame 1.11 and driven to run by a servo motor 1.1, and a material cutting and removing mechanism 1.8 connected to the horizontal terminal of each group of conveying belts, and an inlet detection photoelectric assembly 1.6 and an outlet detection photoelectric assembly 1.7 arranged above the vertical direction of the plurality of conveying belts and arranged in front and back along the horizontal conveying direction.

[0041] Further, each group of conveying belts is closed-loop wound between a set of driving rollers 1.4 and driven rollers 1.5 oppositely arranged on the wire body frame 1.11, a servo driven wheel 1.3 is sleeved on the shaft end of the driving roller 1.4, a servo driving wheel 1.2 is sleeved on the driving shaft of the servo motor 1.1, and a transmission belt is closed-loop wound between the servo driving wheel 1.2 and the servo driven wheel 1.3.

[0042] A waste collection basket 1.9 is arranged below the vertical direction of the material cutting and removing mechanism 1.8, and an electromagnetic valve assembly 1.10 for controlling the operation and opening and closing state of the material cutting and removing mechanism 1.8 is installed on the wire body frame 1.11.

[0043] The material cutting and removing mechanism 1.8 comprises a metal sheet slide 1.8.3 connected with the terminal of the conveying belt in the horizontal direction, one end of the metal sheet slide 1.8.3 is hinged to the wire body frame 1.11, the other end is connected to the driving end of a material cutting and removing cylinder 1.8.1, at least one set of elastic buffer sheets 1.8.4 is arranged below the vertical direction of the metal sheet slide 1.8.3, and the material cutting and removing cylinder 1.8.1 is connected to a set of quick exhaust valves 1.8.2.

[0044] The electromagnetic valve assembly 1.10 comprises a double-electronic-control electromagnetic valve 1.10.1 for controlling and connecting the quick exhaust valves 1.8.2 and a silencer 1.10.2.

[0045] The above receiving blank machine conveying line 1 is mainly used for conveying mosquito-repellent incense tablets from the receiving blank machine. The single mosquito-repellent incense tablets are sequentially conveyed forward along each group of conveying belts. In the conveying process, the mosquito-repellent incense tablets first pass through the warehouse detection photoelectric assembly 1.6, and the warehouse counting of the mosquito-repellent incense tablets is performed by the photoelectric sensor, and the photographing and identification are performed by the visual camera to determine whether the current mosquito-repellent incense tablet is damaged. Then, the mosquito-repellent incense tablet passes through the subsequent warehouse detection photoelectric assembly 1.7 to perform the warehouse counting. Since the spacing value between the warehouse detection photoelectric assembly 1.6 and the warehouse detection photoelectric assembly 1.7 and the running speed of the conveying belt are pre-fixed, the in-out warehouse record of each mosquito-repellent incense tablet can be accurately calculated, and the damaged mosquito-repellent incense tablet can also be clearly recorded and timely disposed.

[0046] When the visual detection identifies that there is a damaged mosquito-repellent incense tablet, after a preset delay, the device PLC sends a signal to the material cutting and removing cylinder 1.8.1 through the double electric control electromagnetic valve 1.10.1. The material cutting and removing cylinder 1.8.1 drives the metal slide 1.8.3 to vertically flip, the damaged mosquito-repellent incense tablet falls downward and is redirected to enter the waste collection basket 1.9 by colliding with the elastic buffer piece 1.8.4. Then, the material cutting and removing cylinder 1.8.1 controls the metal slide 1.8.3 to horizontally reset, and the qualified mosquito-repellent incense tablet can be horizontally conveyed through the metal slide 1.8.3 to the subsequent variable-distance conveying device.

[0047] The variable-distance conveying device comprises a plurality of first variable-distance conveying lines 2 extending obliquely to both sides and a second variable-distance conveying line 3 extending straight in the middle.

[0048] The first variable-distance conveying line 2 is used to significantly expand the spacing of the mosquito-repellent incense tablets conveyed from the receiving blank machine conveying line 1 by the conveying speed and the conveying distance. The first variable-distance line body frame 2.9 is provided with a first variable-distance servo motor 2.1 and a shaft provided with a first variable-distance driving roller 2.4, a first variable-distance driven roller 2.5, and a conveying belt closed-loop wound between the first variable-distance driving roller 2.4 and the first variable-distance driven roller 2.5.

[0049] A first variable-distance servo driven wheel 2.3 is sleeved on the shaft end of the first variable-distance driving roller 2.4, a first variable-distance servo driving wheel 2.2 is sleeved on the driving shaft of the first variable-distance servo motor 2.1, and a transmission belt is closed-loop wound between the first variable-distance servo driving wheel 2.2 and the first variable-distance servo driven wheel 2.3. Under the driving of the first variable-distance servo motor 2.1, the transmission belt drives the conveying belt to run to horizontally convey the mosquito-repellent incense tablets conveyed from the receiving blank machine conveying line 1 forward.

[0050] A blocking roller assembly 2.7 and a counting photoelectric detection switch 2.8 are arranged above the vertical direction of the first variable distance line body frame 2.9, the blocking roller assembly 2.7 is driven by a pneumatic cylinder to extend downward in the vertical direction to block the mosquito-repellent incense pieces on the conveying belt, so that the distance between the mosquito-repellent incense pieces and the front mosquito-repellent incense piece is enlarged to a set value; the counting photoelectric detection switch 2.8 sequentially counts the passing mosquito-repellent incense pieces, thereby providing quantity statistics for subsequent stacking operations;

[0051] Since the first variable distance conveying line 2 is located at the outer side of the variable distance conveying device, the included angle between the first variable distance conveying line 2 and the conveying direction of the receiving blank machine conveying line 1 is large. In order to improve the smoothness of the connection and transmission of the mosquito-repellent incense pieces between the two groups of equipment, a transition roller assembly 2.6 is arranged at the conveying front end of the first variable distance line body frame 2.9, the transition roller assembly 2.6 includes a plurality of groups of roller bearings 2.6.1 which are connected obliquely and arranged in parallel with each other, the number of roller bearings 2.6.1 in each group is different and gradually decreases along the conveying direction; when the mosquito-repellent incense pieces enter the first variable distance conveying line 2 from the metal slide 1.8.3, the transition roller assembly 2.6 can transition and receive the mosquito-repellent incense pieces through the plurality of groups of roller bearings 2.6.1, so that the mosquito-repellent incense pieces can more smoothly enter the first variable distance conveying line 2.

[0052] The main function of the above-mentioned first variable distance conveying line 2 is to continuously convey the queue of mosquito-repellent incense pieces conveyed from the receiving blank machine conveying line 1, and at the same time, the distance between the adjacent mosquito-repellent incense pieces in the queue is significantly increased during the continuous conveying process, and the size of the distance value can be randomly adjusted and changed according to the number of subsequent stacking.

[0053] The second variable distance conveying line 3 is located at the middle part of the whole variable distance conveying device, and is also used for connecting and conveying the mosquito-repellent incense pieces conveyed from the receiving blank machine conveying line 1, and the second variable distance conveying line 3 has a smaller distance enlarging effect on the front and rear conveying mosquito-repellent incense pieces.

[0054] The structure design of the second variable distance conveying line 3 is basically the same as that of the first variable distance conveying line 2, except that the second variable distance conveying line 3 does not have a transition roller assembly 2.6. Specifically,

[0055] The second variable distance conveying line 3 has a second variable distance line body frame 3.8, a second variable distance servo motor 3.1 and a shaft are installed on the second variable distance line body frame 3.8, a second variable distance driving roller 3.4, a second variable distance driven roller 3.5, and a conveying belt which is closed-loop wound between the second variable distance driving roller 3.4 and the second variable distance driven roller 3.5 are installed on the shaft;

[0056] The shaft end of the second variable distance active roller 3.4 is sleeved with a second variable distance servo driven wheel 3.3, the driving shaft of the second variable distance servo motor 3.1 is sleeved with a second variable distance servo drive wheel 3.2, and a transmission belt is looped between the second variable distance servo drive wheel 3.2 and the second variable distance servo driven wheel 3.3; under the driving of the second variable distance servo motor 3.1, the transmission belt drives the conveying belt to run to horizontally convey the mosquito-repellent incense tablets conveyed from the butt joint receiving machine conveying line 1 forward;

[0057] The second blocking roller assembly 3.7 and the second counting photoelectric detection switch 3.8 are arranged vertically above the second variable distance line frame 3.8, the second blocking roller assembly 3.7 is driven by a gas cylinder to extend downward vertically to block the mosquito-repellent incense tablets on the conveying belt, so that the interval between the mosquito-repellent incense tablets and the front mosquito-repellent incense tablets is enlarged to a set value; the second counting photoelectric detection switch 3.8 sequentially counts the passing mosquito-repellent incense tablets, thereby providing quantity statistics for subsequent stacking operation.

[0058] The laminated head alignment material sorting machine 4 comprises a device main frame 4.3, and a laminated head alignment assembly 4.1 and a conveying and buffering assembly 4.2 arranged on the device main frame 4.3.

[0059] The laminated head alignment assembly 4.1 is used for connecting and conveying the mosquito-repellent incense tablets conveyed from the first variable distance conveying device 2 or the second variable distance conveying device 3, and then performing laminated head alignment material sorting action on the laminated head alignment assembly 4.1 with the mosquito-repellent incense tablets in a set number (such as 5 pieces) as a group; the laminated head alignment assembly 4.1 comprises a rack, a laminated head alignment servo motor 4.1.3 arranged on the rack, a laminated chain 4.1.1 driven by the laminated head alignment servo motor 4.1.3 to run circularly in a horizontal direction, a head alignment material sorting knurled roller 4.1.4 and an auxiliary smooth roller 4.1.5 arranged on both sides of the laminated chain 4.1.1, and a fire head limiting plate 4.1.7 arranged on one side of the laminated chain 4.1.1.

[0060] Specifically, a plurality of mosquito-repellent incense tablet supporting plates 4.1.2 are arranged vertically at equal intervals on the laminated chain 4.1.1, and the head alignment material sorting knurled roller 4.1.4 is driven by an alternating current induction motor 4.1.6 and a chain sprocket assembly to rotate reciprocally in a vertical direction.

[0061] Mosquito incense piece from the first variable distance conveying line 2 or the second variable distance conveying line 3 is conveyed and carried on the above-mentioned mosquito incense piece supporting plate 4.1.2, and through the counting of the first counting photoelectric detection switch 2.8 or the second counting photoelectric detection switch 3.8, when a preset number of mosquito incense pieces (such as 5 pieces) are all stacked on a certain mosquito incense piece supporting plate 4.1.2, the control system PLC drives the stacking chain 4.1.1 to move forward in the horizontal direction by a certain distance through the stacking head servo motor 4.1.3, so that the mosquito incense piece supporting plate 4.1.2 realizes a preset displacement each time, so that the group of stacked mosquito incense pieces is conveyed by a standard conveying distance.

[0062] In the above intermittent conveying process, the control system PLC drives the stacking head arrangement knurled roller 4.1.4 to rotate through the alternating current induction motor 4.1.6 and the chain sprocket assembly, and the group of stacked mosquito incense pieces rotates along the axial center under the joint rotating and friction of the stacking head arrangement knurled roller 4.1.4 and the auxiliary smooth roller 4.1.5, so that the fire head edge of the group of mosquito incense pieces is clamped and embedded on the fire head limiting plate 4.1.7, thereby the fire head of the group of mosquito incense pieces is arranged uniformly; the arranged group of mosquito incense pieces is conveyed to the conveying buffer assembly 4.2 in sequence along the stacking chain 4.1.1.

[0063] Through the stacking head working principle comparison diagram as shown in Figure 5-2 and Figure 5-3 , under the joint action of the stacking head arrangement knurled roller 4.1.4 and the auxiliary smooth roller 4.1.5, the mosquito incense piece is continuously rotated to achieve the stacking head operation, that is, the fire head edge is clamped and embedded on the fire head limiting plate 4.1.7.

[0064] The conveying buffer assembly 4.2 has a multi-section conveying assembly, and in the embodiment, a two-section structure of the first section belt line 4.2.1 driven to operate by the first section alternating current induction motor 4.2.2 and the second section belt line 4.2.3 driven to operate by the second section servo motor 4.2.4 is adopted; the first section belt line 4.2.1 and the second section belt line 4.2.3 are horizontally butted; the conveying buffer assembly 4.2 is designed to be two-section conveying, which provides error redundancy buffer for the conveying of the group of mosquito incense pieces after the arrangement and stacking, so as to prevent the mutual conflict and interference of the front and rear groups of mosquito incense pieces from stacking due to the inconsistent conveying beats of the above-mentioned first variable distance conveying line 2 and the second variable distance conveying line 3.

[0065] The first section belt line 4.2.1 is used for connecting, conveying and buffering the group of mosquito incense pieces conveyed from the stacking head assembly 4.1, and the second section belt line 4.2.3 is used for connecting, conveying and pushing out the group of mosquito incense pieces conveyed from the first section belt line 4.2.1 to the subsequent material pushing assembly 5;

[0066] Under the control of the control system PLC, the first section AC induction motor 4.2.2 and the second section servo motor 4.2.4 keep the interval action working rhythm, when the mosquito-repellent incense pieces are conveyed by the second section belt line 4.2.3 to the material pushing assembly 5, the first section belt line 4.2.1 conveys the mosquito-repellent incense pieces cached thereon to the second section belt line 4.2.3, at the same time, the first section belt line 4.2.1 receives the next group of mosquito-repellent incense pieces conveyed from the stack head assembly 4.1;

[0067] The working rhythm from the stack head assembly 4.1 to the first section belt line 4.2.1, the second section belt line 4.2.3 and the material pushing assembly 5 keeps consistent, through the action cooperation between the above-mentioned assemblies, the mosquito-repellent incense pieces are sequentially subjected to the material arrangement, stacking and head alignment action, thereby realizing the full-automatic material arrangement and stacking process.

[0068] The material pushing assembly 5 comprises a material pushing platform 5.1, a push rod assembly 5.3 driven by a rodless cylinder 5.2 and an electromagnetic valve assembly 5.4 arranged on the material pushing platform 5.1, and a material detection photoelectric sensor 5.5; Figure 6 The arrow in the figure indicates the direction of the mosquito-repellent incense pieces entering and leaving the material pushing assembly 5.

[0069] When the group of mosquito-repellent incense pieces are conveyed to the material pushing platform 5.1 by the stack head assembly 4, the material detection photoelectric sensor 5.5 detects the group of mosquito-repellent incense pieces, the rodless cylinder 5.2 and the electromagnetic valve assembly 5.4 are controlled by the control system PLC to drive the push rod assembly 5.3 to push forward to push the mosquito-repellent incense pieces away from the material pushing platform 5.1, then the push rod assembly 5.3 retreats backward to avoid the next group of mosquito-repellent incense pieces, the control system PLC controls the next group of mosquito-repellent incense pieces to be conveyed to the material pushing platform 5.1 by the stack head assembly 4, and the entering and leaving the material pushing assembly 5 and the pushing mosquito-repellent incense pieces action cycle reciprocate.

[0070] Based on the structure design of the above-mentioned mosquito-repellent incense piece automatic material arrangement and stacking device, the following mosquito-repellent incense piece automatic material arrangement and stacking method is realized:

[0071] (I) The mosquito-repellent incense pieces produced by the receiving machine are continuously conveyed to the receiving machine conveying line 1 in multiple queues;

[0072] (II) The quality of each single mosquito-repellent incense piece is detected on the receiving machine conveying line 1, and the in-and-out warehouse counting is performed, the unqualified mosquito-repellent incense pieces are removed from the conveying line, and the qualified mosquito-repellent incense pieces are conveyed to the stack head assembly 4 by the variable pitch conveying device;

[0073] A material breaking and removing mechanism 1.8 is arranged at the horizontal terminal end of the receiving machine conveying line 1. A visual camera is used for shooting and identification to determine whether the currently conveyed mosquito-repellent incense sheet is damaged. If so, the PLC will send a signal to the material breaking and removing cylinder 1.8.1 through the double electric control electromagnetic valve 1.10.1. The material breaking and removing cylinder 1.8.1 drives the metal sheet slide 1.8.3 to flip vertically, and the damaged mosquito-repellent incense sheet falls down. Then, the material breaking and removing cylinder 1.8.1 controls the metal sheet slide 1.8.3 to reset horizontally. The qualified mosquito-repellent incense sheet can be conveyed horizontally through the metal sheet slide 1.8.3 to the subsequent variable-distance conveying device.

[0074] The variable-distance conveying device includes a plurality of first variable-distance conveying lines 2 extending obliquely to both sides and a second variable-distance conveying line 3 extending linearly in the middle. According to the requirements of the conveying rear-end stacking and transfer operation, the distance between the adjacent mosquito-repellent incense sheets in the multiple conveying queues is adjusted by adjusting the conveying speed of the first variable-distance conveying lines 2 and the second variable-distance conveying line 3.

[0075] Further, a transition roller assembly 2.6 can be arranged at the connection and conveying part between the first variable-distance conveying line 2 and the receiving machine conveying line 1. The transition roller assembly 2.6 includes a plurality of roller bearings 2.6.1 arranged obliquely and parallel to each other. The number of roller bearings 2.6.1 in each group is different and gradually decreases along the conveying direction.

[0076] (Three), the sheet aligning and sorting machine 4 includes a sheet aligning and sorting assembly 4.1 and a conveying and buffering assembly 4.2. The sheet aligning and sorting assembly 4.1 connects and conveys the single mosquito-repellent incense sheets continuously conveyed from the variable-distance conveying device, performs the mosquito-repellent incense sheet aligning and sorting action in a set number of groups, and intermittently conveys the stacked mosquito-repellent incense sheets to the conveying and buffering assembly 4.2 at a set standard conveying distance.

[0077] The sheet aligning and sorting assembly 4.1 is provided with a plurality of mosquito-repellent incense sheet supporting plates 4.1.2 vertically and equidistantly on the sheet conveying assembly. The sheet conveying assembly rotates vertically and reciprocally.

[0078] The mosquito-repellent incense sheets conveyed from the variable-distance conveying device are carried on the mosquito-repellent incense sheet supporting plates 4.1.2. The number of the mosquito-repellent incense sheets is counted through the counting photoelectric detection switch. After the preset number of mosquito-repellent incense sheets are all stacked on the mosquito-repellent incense sheet supporting plates 4.1.2, the control system PLC drives the sheet conveying assembly to advance intermittently by a set distance. The stacked mosquito-repellent incense sheets are conveyed forward by a standard conveying distance.

[0079] In the intermittent conveying process, the control system PLC drives the rotating of the head-arranging knurled roller 4.1.4 through the AC induction motor 4.1.6 and the chain and sprocket assembly. The stack of mosquito-repellent incense pieces rotates along the axial center under the joint rotating and friction of the head-arranging knurled roller 4.1.4 and the auxiliary smooth roller 4.1.5. The head edges of the mosquito-repellent incense pieces are clamped to the head limiting plate 4.1.7.

[0080] The conveying and buffering assembly 4.2 has a multi-section conveying assembly. The conveying assemblies are connected intermittently to convey and buffer the stack of mosquito-repellent incense pieces from the stack head-arranging assembly 4.1. The stack of mosquito-repellent incense pieces is then pushed out by the material pushing assembly 5.

[0081] The above content, combined with the embodiments shown in the drawings, is only a preferred scheme for achieving the purpose of the present application. Those skilled in the art can be inspired by this to directly deduce other alternative structures that meet the design concept of the present application. Other structural features obtained thereby shall also belong to the scope of the present application.
