Description

Technical Field

[0001] This invention relates to the field of roller conveyor technology, and more particularly to a stainless steel roller conveyor and method. Background Technology

[0002] Roller conveyors are suitable for transporting various goods, such as intelligent post-harvest packaging of agricultural products, laser-cut components transported away from the conveyor line, and intelligently welded parts. Multi-section roller conveyors are favored by many users because they offer the advantage of individual section control for preventing line congestion. Due to different application scenarios, the required length of roller conveyors varies from user to user. Currently, manufacturers offer roller conveyors broken down into multiple roller conveyor units, allowing users to select and purchase the appropriate number of units based on their required length and assemble them themselves.

[0003] After research, it was found that although existing roller conveyors have the function of independent control of opening and closing, in actual conveying process, it is still necessary to have personnel to observe the density of goods on the line and adjust the conveying accordingly. This not only wastes labor, but also cannot achieve seamless connection of feeding, thus reducing conveying efficiency. Therefore, we propose a new type of stainless steel roller conveyor and conveying method. Summary of the Invention

A C-shaped clamp is rotatably sleeved on the outer circumference of the transmission rod near the bottom end. A drive motor is fixed on the side of the second support frame away from the grooved slide rail, and a turntable is fixed at the top of the output shaft of the drive motor. A rack push-pull rod is rotatably connected to the upper surface of the turntable near the circumferential edge. The rack push-pull rod passes through the C-shaped clamp and meshes with the rubbing gear D.

[0014] A method for conveying stainless steel rollers includes the following steps:

[0015] S1: First, the material runs towards the end position via the original roller conveyor. When the material reaches the position of photoelectric sensor one, roller conveyor one is started and begins to carry the material. When the material reaches the position of photoelectric sensor two, roller conveyor two begins to carry the material and continues to run. When the material leaves the position of photoelectric sensor two, roller conveyor one stops running. When the material reaches the position of photoelectric sensor three, that is, when it reaches the tail panel, roller conveyor two stops running.

[0016] At the same time, when photoelectric sensor 3 detects material, roller conveyor 2 cannot start through photoelectric sensor 2. When photoelectric sensor 3 detects material and material reaches photoelectric sensor 2, roller conveyor 1 stops running. After the material at the position irradiated by photoelectric sensor 3 is transported away, all lines resume operation.

[0017] S2: When the material reaches the photoelectric position three, it will hit the extended strip plate, which will cause the connected contact head and electrical contact piece to separate, thereby de-energizing the geared motor that drives the roller conveyor two.

[0018] S3: When the original roller conveyor receives material, the drive motor in the anti-wear mechanism is activated. At this time, under the transmission of a series of transmissions such as the rack and pinion push rod and the driven gear, the two swing plates swing alternately to guide the material to run alternately from the two lines near the middle.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. By setting up a three-section conveying method, and each section is equipped with its own independent transmission mechanism, the overall line can more conveniently control the material conveying distance. With the sensing mechanism set at the end of each section, the material can move forward automatically and orderly at equal intervals. After the material that finally reaches the tail plate is taken out, the next material can quickly follow, improving the overall conveying efficiency.

[0021] 2. Through the oil storage tank and oil-absorbing brush, the roller can intermittently pick up lubricating oil as it rotates, and then flow into the bearing to automatically lubricate it.

[0022] 3. By using the strip baffle and compression spring, the material can be prevented from being bumped by the strong impact of inertia on the surface of the trough baffle when it is about to reach the photoelectric position 3. This setting can play a certain buffering role.

[0023] 4. By setting two swing guardrails that can swing left and right, the material can be prevented from moving forward from one position continuously during the conveying process, which would cause uneven wear of the roller conveyor and make it easy for the material to deviate during the conveying process. This setting allows the material to move forward alternately from the middle position of the roller conveyor. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] In this embodiment, refer to Figures 1-11 A stainless steel roller conveyor includes a feeding frame 1, a first frame 2, and a second frame 4 connected together. A primary roller conveyor 12 is mounted on the feeding frame 1, and roller conveyors 1 9 and 2 7 are respectively mounted on the top of the first frame 2 and the second frame 4. The conveying directions of the primary roller conveyor 12, roller conveyor 1 9, and roller conveyor 2 7 are in a straight line. The front of the feeding frame 1, the first frame 2, and the second frame 4 are respectively equipped with a transmission mechanism 14 capable of controlling the independent operation of each of the primary roller conveyors 12, roller conveyor 1 9, and roller conveyor 2 7. A geared motor 142 is provided; the top of the material receiving frame 1, frame one 2 and frame two 4 are respectively fixed with parallel connecting strips 11 on the front and rear sides to fix the three frames together. A light sensing mechanism is provided above the connecting strip 11 near the rear side, and the light sensing mechanism includes photoelectric one 10, photoelectric two 8 and photoelectric three 6 fixed at the end of each conveying section to send start and stop signals to the three geared motors 142. The two connecting strips 11 are fixed with the same tail guard plate 5 at the end away from the original roller table 12.

[0038] Specifically, by setting up a three-section conveying method, and each section is equipped with its own independent transmission mechanism 14, the overall line can more conveniently control the material conveying distance. With the sensing mechanism set at the end of each section, the material can move forward automatically and orderly at equal intervals. After the material that finally reaches the tail panel 5 is taken out, the next material can quickly follow, improving the overall conveying efficiency.

[0039] Reference Figures 1-2 Photoelectric sensor 10 is fixed to the upper surface of the connecting strip 11 at the junction of the incoming material frame 1 and the frame 1 2; photoelectric sensor 28 is fixed to the upper surface of the connecting strip 11 at the junction of the frame 1 2 and the frame 2 4; photoelectric sensor 36 is fixed to the upper surface of the connecting strip 11 at the end away from the incoming material frame 1; photoelectric sensor 10, photoelectric sensor 28 and photoelectric sensor 36 are connected to the same controller through signal lines, and the signal output terminal of the controller is connected to the control switches of the three geared motors 142 through signal lines respectively;

[0040] With this setup, when the material reaches position 10 of photoelectric sensor 1, roller conveyor 9 starts to carry the material. When the material reaches position 8 of photoelectric sensor 2, roller conveyor 7 starts to carry the material and continues to run. When the material leaves position 8 of photoelectric sensor 2, roller conveyor 9 stops running. When the material reaches position 6 of photoelectric sensor 3, that is, when it reaches the tail guardrail 5, roller conveyor 7 stops running.

[0041] Reference Figures 1-3The incoming material frame 1, frame 2, and frame 4 have the same overall structure. The incoming material frame 1 includes two parallel front and rear side plates located at the front and rear ends of the original roller conveyor 12, respectively. The transmission mechanism 14 includes a motor fixing plate 141 fixed to the bottom of the front side plate near the incoming material end, and a reduction motor 142 fixed to the back of the motor fixing plate 141. The reduction motor 142 is located below the original roller conveyor 12. The output shaft of the reduction motor 142 passes through the motor fixing plate 141 and is fixed with a drive pinion. All original roller conveyors 12, roller conveyor 9, and roller conveyor 7 are the same size and have roller heads reserved at both ends. A pulley is fixed to the end of each roller head near the transmission mechanism 14. Symmetrical pulleys A1410 are fixed to the lower part of the front side plate near both ends. The same conveyor belt 144 is wound around the outer circumference of all pulleys 1 and the two pulleys A1410 below them. A pressure roller 149 is installed on the front side plate between two adjacent pulleys 1, near the top. Two symmetrical rectangular sliding holes 147 are opened at two intervals near the middle of the side plate, and a bearing seat 143 is slidably connected to each of the two rectangular sliding holes 147. A short shaft extending horizontally forward is rotatably connected to each of the bearing seats 143. The ends of the two short shafts are fixed with adjusting pressure rollers 148 that press down on the conveyor belt 144. The bottom of the front side plate has two sliding insertion holes that communicate with the corresponding rectangular sliding holes 147. A guide rod is slidably connected to each of the two sliding insertion holes, and the top of the guide rod is fixed to the corresponding shaft. The surface of the bearing 143; pulling down the two guide rods controls the adjustment roller 148 to press down the conveyor belt 144. The bottom ends of the two guide rods are fixed with the same connecting rod 145, and the middle of the connecting rod 145 is screwed with an adjusting screw 146; the end of the roller head near the geared motor 142 is also fixed with a transmission gear disc 1411 that meshes with the drive pinion; by rotating the adjusting screw 146, the conveyor belt 144 can be tightened to improve the conveying effect and prevent the conveyor belt 144 from slipping.

[0042] Reference Figures 8-9 All the rear side plates have the same oil storage tank 16 fixed on the rear side below the roller head, and the roller head end near the rear side of the device is fitted with a shaft head sleeve 17. The outer circumference of the shaft head sleeve 17 is cut with a cross-section, and a return spring 19 is fixed on the cross-section. The end of the return spring 19 away from the shaft head sleeve 17 is fixed with an oil-absorbing brush bristle 20. The roller head is fitted with a bearing 18. Through the oil storage tank 16 and the oil-absorbing brush bristle 20, the roller can be intermittently coated with lubricating oil when the roller rotates, and then flow into the bearing 18, so as to automatically lubricate the bearing 18.

[0043] Reference Figure 2 and Figure 8The lower surfaces of frame 1 2 and frame 2 4 are both fixed with support frame 1 3, and support frame 2 15 is provided below the material receiving frame 1 to fix the front side plate and the rear side plate. The height of support frame 1 3 and support frame 2 15 is adjustable. With this setting, the top conveying surfaces of roller conveyor 1 9, roller conveyor 2 7 and the original roller conveyor 12 can be adjusted to be on the same horizontal plane.

[0044] Reference Figures 5-7 The tail section 5 includes a grooved baffle 501 fixed to the ends of two connecting strips 11. The bottom of the grooved baffle 501 faces the roller conveyor 7. Sliding bearings are embedded near both ends of the bottom of the grooved baffle 501. Guide rods 509 are slidably connected to the two sliding bearings. The same strip-shaped abutment 502 is fixed to one end of the two guide rods 509 near the roller conveyor 7. The strip-shaped abutment 502 is located above the conveying plane. A compression spring 503 is fixed to the middle of the strip-shaped abutment 502 near the side of the grooved baffle 501. A round hole 504 is opened in the middle of the grooved baffle 501 for the compression spring 503 to pass through. A C-shaped baffle 505 is fixed to the side of the grooved baffle 501 away from the roller conveyor 7 near the round hole 504 to fix the other end of the compression spring 503.

[0045] By using the strip baffle 502 and compression spring 503, when the conveyed material is about to reach the photoelectric three-6 position, it can be prevented from being bumped by the surface of the trough baffle 501 due to strong inertia. This setting can play a certain buffering role.

[0046] Reference Figures 5-7 The C-shaped baffle 505 has a hole in the middle, through which a round rod top rod 506 is slidably connected. The round rod top rod 506 passes through the compression spring 503 and is fixed to the surface of the strip plate 502. The other end of the round rod top rod 506 is fixed with a Z-shaped pressure rod 507. An electrical contact piece 508 is fixed on the side of the groove baffle 501 away from the roller conveyor 7, below the end of the Z-shaped pressure rod 507. A contact head is fixed on the Z-shaped pressure rod 507. The contact head and the electrical contact piece 508 are connected in series in the control circuit of the reduction motor 142 on the roller conveyor 7 to prevent the roller conveyor 7 from continuing to run if the photoelectric sensor 3 6 fails to detect material.

[0047] Reference Figure 2 , Figure 5 , Figure 8 , Figures 10-11The second support frame 15 is equipped with an anti-wear mechanism 13, which includes a grooved slide rail 1310 fixed to the side of the second support frame 15 with its opening facing the first support frame 3. The grooved slide rail 1310 has two protruding sliders slidably connected within its groove, and a rack rod is fixed between the two protruding sliders on the side closest to the bottom of the groove. The bottom of the groove of the grooved slide rail 1310 has a through hole for the rack rod to slide through. Ordinary bearing assemblies 1311 are fixed on the side of each of the two protruding sliders away from the bottom of the groove, and each ordinary bearing assembly 1311 contains... Rotary connection is provided with a vertically upward extending actuating rod 1312 that passes through the original roller conveyor 12. The two actuating rods 1312 are parallel to each other and the distance between them is equal to two-thirds of the length of a single roller in the original roller conveyor 12. The top of each actuating rod 1312 is fixed with a swing guard plate 135, and the lower surface of each swing guard plate 135 away from the actuating rod 1312 is fixed with a guide shaft rod 134. The lower surface of each of the two connecting strips 11 away from the tail guard plate 5 is fixed with parallel strips 137. Each strip 137 has a strip-shaped sliding hole 136 in the middle that forms a sliding fit with the guide shaft rod 134.

[0048] By setting two swing guardrails 135 that can swing left and right, the material can be prevented from moving forward from a certain position during the conveying process, which would cause uneven wear of the roller conveyor and make it easy for the material to deviate during the conveying process. This setting allows the material to move forward alternately from the middle position of the roller conveyor.

[0049] Reference Figure 2 , Figure 8 , Figures 10-11 An arched shaft bracket 131 with an opening facing downwards is fixed in the middle of the support frame 15. An anti-slip bearing is embedded in the middle of the arched shaft bracket 131, and a transmission rod 132 is rotatably connected to the anti-slip bearing. A driven gear 133 and a rubbing gear D139 are fixed at the upper and lower ends of the transmission rod 132, respectively, and the driven gear 133 meshes with a rack. A C-shaped clamp is rotatably fitted onto the outer circumference of the transmission rod 132 near its bottom end. A [missing information - likely a component or part] is fixed on the side of the support frame 15 away from the grooved slide rail 1310. A drive motor 138 is provided, and a turntable is fixed to the top of the output shaft of the drive motor 138. A rack and pinion push rod 1313 is rotatably connected to the upper surface of the turntable near the circumferential edge. The rack and pinion push rod 1313 passes through a C-shaped plate and meshes with a rubbing gear D139. With this arrangement, the reciprocating rotation of the rubbing gear D139 can be converted into two boss sliders sliding back and forth in the grooved slide rail 1310, thereby allowing the two swinging plates 135 to swing alternately to guide the material to run in the designed direction.

[0050] A method for conveying stainless steel rollers includes the following steps:

[0051] S1: First, the material runs towards the end position via the original roller conveyor 12. When the material reaches the position of photoelectric sensor 10, roller conveyor 9 is started and begins to carry the material. When the material reaches the position of photoelectric sensor 28, roller conveyor 27 begins to carry the material and continues to run. When the material leaves the position of photoelectric sensor 28, roller conveyor 9 stops running. When the material reaches the position of photoelectric sensor 36, that is, when it reaches the tail guardrail 5, roller conveyor 27 stops running.

[0052] At the same time, when photoelectric sensor 36 detects material, roller conveyor 27 cannot be started by photoelectric sensor 28. That is, only one material can be guaranteed on roller conveyor 27. When photoelectric sensor 36 detects material and material reaches photoelectric sensor 28, roller conveyor 19 stops running. After the material at the position irradiated by photoelectric sensor 36 is transported away, all lines resume operation.

[0053] S2: When the material reaches the photoelectric three position 6, it will hit the extended strip plate 502, which will cause the contact head and electrical contact piece 508 connected together to separate, thereby de-energizing the reduction motor 142 used to drive the roller conveyor two 7.

[0054] S3: When the original roller conveyor 12 receives material, the drive motor 138 in the anti-wear mechanism 13 is activated. At this time, under the transmission of a series of transmissions such as the rack and pinion push rod 1313 and the driven gear 133, the two swing plates 135 swing alternately to guide the material to run alternately from the two lines near the middle, preventing continuous friction on a fixed position of the roller conveyor and reducing the wear of the roller conveyor.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
