Description

Technical Field

[0001] The utility model relates to the technical field of cigarette making equipment, in particular to a conveyor material sizing device. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] The storage conveyor is a belt conveyor with a certain storage function that has been newly adopted by tobacco silk production enterprises in recent years. The structure mainly includes a feeding bin composed of a horizontal belt conveyor, an inclined belt conveyor and its side walls. The inclined belt is equipped with rake nails. The horizontal belt stops running after transporting the material to the intersection of the horizontal belt and the inclined belt. The rolling rake nails lift the material between the inclined belt and the inclined flat belt. In order to detect the material between the inclined belt and the inclined belt, so as to stop the horizontal belt, the photoelectric tube that controls the start and stop of the horizontal belt of the feeder is generally installed on the upper side wall of the intersection of the horizontal belt and the inclined belt. When the material height at the intersection of the horizontal belt and the inclined belt is greater than 500mm, the photoelectric tube generates a stop signal for the horizontal belt motor.

[0004] There are still the following technical problems in the material transportation process of warehouse conveyors:

[0005] (1) Because the horizontal belt drive motor adopts continuous operation mode, when it receives the stop signal, due to inertia, the materials placed on the horizontal belt will sometimes splash part of the materials in the direction of the inclined belt. When there is too much material at the junction of the inclined belt and the horizontal belt, the thickness of the material on the inclined belt will be too large, resulting in too much material in front of the feed roller. At this time, the material will pass over the feed roller, resulting in the overall thickness of the material on the inclined belt being too thick, which will cause the inclined belt motor to overload, seriously affecting the continuity of the production process and the stability of product quality.

[0006] (2) Opposite-beam photoelectric tubes are generally installed on the baffles on both sides of the conveyor belt. When the material passes through the opposite-beam photoelectric tube's opposite-beam area, the detection is completed. The opposite-beam photoelectric tubes of existing storage-type conveyors are fixedly installed. When the material thickness is less than the installation height of the opposite-beam photoelectric tube, the material cannot pass through the opposite-beam area, making it impossible for the opposite-beam photoelectric tube to detect materials with a smaller thickness. The opposite-beam photoelectric tubes installed on existing conveyors cannot be adjusted according to the material detection thickness. Utility Model Content

[0007] In order to overcome the above-mentioned deficiencies in the prior art, the utility model provides a conveyor material leveling device.

[0008] To achieve the above objectives, one or more embodiments of the present invention provide the following technical solutions:

[0009] A conveyor material leveling device comprises a horizontal conveyor belt, an inclined conveyor belt, a diffuse reflection photoelectric switch and a beam photoelectric switch. The inclined conveyor belt is installed at the end of the horizontal conveyor belt through a bracket, and the diffuse reflection photoelectric switch is slidably installed on the side wall of the bracket. The diffuse reflection photoelectric switch is located directly above the intersection of the horizontal conveyor belt and the inclined conveyor belt. A material discharging roller is installed on the inclined conveyor belt, and a bracket is arranged on one side of the material discharging roller and close to the direction of the diffuse reflection photoelectric switch. The beam photoelectric switch is slidably arranged on the bracket.

[0010] It is further configured that observation windows are arranged on both sides of the inclined conveyor belt, brackets are vertically installed on the observation windows, and a beam-type photoelectric switch is installed on the upper end of the bracket.

[0011] It is further configured that the observation window is made of polymethyl methacrylate.

[0012] It is further configured that a slide groove is provided on the bracket, the diffuse reflection photoelectric switch is fixed on the slide plate, and the opposing beam photoelectric switch can be fixed on the slide plate.

[0013] It is further configured that a limit block is provided on the side wall of the slide plate, and the slide plate is slidably arranged in the slide groove through the limit block.

[0014] It is further configured that a distance is set between the end of the limit block and the side wall of the slide groove.

[0015] It is further configured that a threaded hole is provided through the limit block and the slide plate, a bolt is passed through the limit threaded hole, and the end of the bolt is installed with a nut.

[0016] It is further configured that the bolt passes through the protruding portion of the slide slot to install the nut.

[0017] It is further configured that the output ends of the diffuse reflection photoelectric switch and the through-beam photoelectric switch are connected to the input end of the terminal device.

[0018] It is further configured that the diffuse reflection photoelectric switch and the through-beam photoelectric switch are both connected to the terminal device via wireless communication.

[0019] One or more of the above technical solutions have the following beneficial effects:

[0020] (1) A diffuse reflection photoelectric switch is installed above the intersection of the horizontal conveyor belt and the inclined conveyor belt of the storage conveyor to detect the material height at the intersection of the horizontal belt and the inclined belt. Then, a through-beam photoelectric switch is installed on both sides of the transmission belt in front of the inclined belt feed roller to detect the material thickness on the feeding side of the feed roller. Through the use of the two photoelectric switches, when the diffuse reflection switch detects that the material height is greater than the set value, the horizontal conveyor belt is controlled to stop. Due to the inertia generated by the stop of the horizontal belt, the material will be splashed onto the inclined conveyor belt. When the material on the inclined conveyor belt is greater than the set value of the through-beam photoelectric switch, the inclined conveyor belt is controlled to stop, avoiding the problem of excessive material thickness on the inclined belt and ensuring uniform material transmission in the storage conveyor.

[0021] (2) The diffuse reflection photoelectric switch and the beam photoelectric switch are movably arranged on the bracket through the slide. After the height of the guard plate is adjusted by installing and removing the bolts and fixing them with bolts and nuts, the positions of the two photoelectric switches can be changed, thereby being able to detect materials of different thicknesses.

[0033] Embodiment 1

[0034] This embodiment discloses a conveyor material leveling device, see Figure 1 , including a horizontal conveyor belt 1, an inclined conveyor belt 2, a diffuse reflection photoelectric switch 3 and a through-beam photoelectric switch 4. The inclined conveyor belt 2 is installed at the end of the horizontal conveyor belt 1 through a bracket 6. The diffuse reflection photoelectric switch 3 is slidably installed on the side wall of the bracket 6. The diffuse reflection photoelectric switch 3 is located directly above the intersection of the horizontal conveyor belt 1 and the inclined conveyor belt 2. A feeding roller 5 is installed on the inclined conveyor belt 2. A bracket 6 is arranged on one side of the feeding roller 5 and close to the diffuse reflection photoelectric switch 3. The through-beam photoelectric switch 4 is slidably arranged on the bracket 6. The diffuse reflection photoelectric switch 3 is installed at a height of about 1200mm directly above the intersection of the horizontal conveyor belt 1 and the inclined conveyor belt 2. The through-beam photoelectric switch 4 is installed at a position about 350mm in front of the feeding roller of the inclined lifting belt, and the vertical height with the inclined conveyor belt 2 is 80mm. In order to ensure normal measurement, the measurement position for height is higher than the measurement installation position for thickness.

[0035] Observation windows 7 are arranged on both sides of the inclined conveyor belt 2, and brackets 6 are installed vertically on the observation windows 7. A beaming photoelectric switch 4 is installed on the upper end of the bracket 6. In order to ensure that the beaming photoelectric switch 4 can detect the material thickness, the beaming photoelectric switch 4 is arranged on both sides of the material.

[0036] The observation window 7 is made of polymethyl methacrylate, and the material accumulation behind the observation window 7 can be observed through the transparent polymethyl methacrylate material.

[0037] See also Figure 2 and Figure 3 A slide groove 61 is provided on the bracket 6, the diffuse reflection photoelectric switch 3 is fixed on the slide plate 62, the through-beam photoelectric switch 4 can be fixed on the slide plate 62, the diffuse reflection photoelectric switch 3 is installed on the slide plate 62 directly above the intersection of the horizontal conveyor belt 1 and the inclined conveyor belt 2, the diffuse reflection photoelectric switch 3 is welded to the slide plate 62, the through-beam photoelectric switch 4 is installed on the bracket 6 arranged perpendicular to the observation window 7, and the through-beam photoelectric switch 4 is welded to the slide plate 62.

[0038] The opposing photoelectric switch 4 sets a limit block 63 on the side wall of the slide plate 62, and the slide plate 62 is slidably set in the slide groove 61 through the limit block 63. A distance is set between the end of the limit block 63 and the side wall of the slide groove 61. The setting of the distance ensures that the limit block 63 can slide in the slide groove 61.

[0039] A threaded hole 64 is formed through the limit block 63 and the slide plate 62, a bolt 65 is passed through the threaded hole 64, the bolt 65 passes through the protruding part of the slide groove 61 to install a nut 66, and after tightening the nut 66, the nut 66 and the bolt 65 press the slide plate 62 tightly onto the bracket 6, thereby completing the fixation of the diffuse reflection photoelectric switch 3 or the through-beam photoelectric switch 4.

[0040] The output ends of the diffuse reflection photoelectric switch 3 and the through-beam photoelectric switch 4 are connected to the input end of the terminal device. The model of the diffuse reflection photoelectric switch 3 is the American Banner diffuse reflection photoelectric tube Q60BB6AF2000Q, the model of the through-beam photoelectric switch 4 transmitting end is the American Banner S186EQ, and the model of the receiving end is S18SP6RQ.

[0041] The diffuse reflection photoelectric switch 3 and the through-beam photoelectric switch 4 are both connected to the terminal device via wireless communication. The terminal device can use an existing PLC module. Specifically, the diffuse reflection photoelectric switch 3 and the through-beam photoelectric switch 4 can use an existing Bluetooth sending module, and the terminal device uses an existing Bluetooth receiving module. The terminal device uses both the Bluetooth sending module and the Bluetooth receiving module without prior art.

[0042] Measures to avoid blocking of the feeding roller 5 are as follows:

[0043] The existing terminal equipment such as the existing PLC module is used to send running and stopping signals to the horizontal belt motor of the feeder through the states of the diffuse reflection photoelectric switch 3 and the opposite-beam photoelectric switch 4 at two positions. When the diffuse reflection photoelectric switch 3 detects that the material height is greater than the set value, the horizontal conveyor belt 1 is controlled to stop. Due to the inertia generated by the stop of the horizontal conveyor belt 1, the material will be splashed onto the inclined conveyor belt. When the material on the inclined conveyor belt 2 is greater than the set value of the opposite-beam photoelectric switch 4, the inclined conveyor belt 2 is controlled to stop to avoid the splashed material clogging the feeding roller 5. At the same time, the motor 8 adopts the existing stepping motor. The motor 8 runs in a periodic inch motion mode of running for 1S and stopping for 3 seconds, which effectively detects and controls the material output. The motor 8 controls the operation of the horizontal conveyor belt 1 and the inclined conveyor belt 2 according to the states of the diffuse reflection photoelectric switch 3 and the opposite-beam photoelectric switch 4, which is easy to achieve in the prior art.

[0044] The adjustment methods of diffuse reflection photoelectric switch 3 and beam-type photoelectric switch 4 are as follows:

[0045] The opposing photoelectric switch 4 sets a limit block 63 on the side wall of the slide plate 62, and the slide plate 62 is slidably set in the slide groove 61 through the limit block 63. A distance is set between the end of the limit block 63 and the side wall of the slide groove 61. The setting of the distance ensures that the limit block 63 can slide in the slide groove 61.

[0046] A threaded hole 64 is formed through the limit block 63 and the slide plate 62, a bolt 65 is passed through the threaded hole 64, the bolt 65 passes through the protruding part of the slide groove 61 to install a nut 66, and after tightening the nut 66, the nut 66 and the bolt 65 press the slide plate 62 tightly onto the bracket 6, thereby completing the adjustment and fixation of the diffuse reflection photoelectric switch 3 or the through-beam photoelectric switch 4.

[0047] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
