Description

Technical Field

[0001] This utility model relates to a compact linear roller conveyor that can be started and rotated by fire alarm linkage or manual control, belonging to the field of logistics and warehousing. Background Technology

[0002] In the existing logistics and warehousing field, conveyor lines used in express delivery, e-commerce, and manufacturing enterprise warehousing and distribution centers are typically designed with different functional zones. To cope with sudden safety accidents such as fires, it is necessary to implement lifting fire-resistant partitions between different zones. Accordingly, the conveyor line needs to be equipped with a flip-off disconnect mechanism at this location to cooperate with the lifting and lowering of fire-resistant roller shutters.

[0003] Due to space constraints in various sites, existing tilting conveyors generally employ three-phase asynchronous motors for drive. The arrangement of these electric tilting roller assemblies is limited by site conditions, resulting in significant drawbacks: Firstly, the accuracy of the tilting angle is low. Existing three-phase asynchronous motors, which use photoelectric positioning to trigger the tilting, have a certain degree of error in tilting positioning, and the photoelectric position must be adjustable. Secondly, the output parameters of three-phase asynchronous motors cannot be adjusted; once the tilting angle is set, it cannot be adjusted, thus resulting in low overall tilting efficiency.

[0004] In view of the above, this patent application is hereby filed. Utility Model Content

[0005] The compact electric tilting linear roller conveyor proposed in this utility model aims to solve the problems existing in the prior art by proposing a solution that uses a servo motor to drive a linear electric cylinder to extend and retract, thereby realizing the tilting of the conveyor around the axis. By controlling the tilting angle and the position of the conveyor line through servo distance control, the overall structure design is made more compact and suitable for confined space conditions, thereby improving the control accuracy and efficiency of the tilting angle of the conveyor line.

[0006] To achieve the above design objectives, the compact electric tilting linear roller conveyor includes a fixed section and a tilting section of an electric roller conveyor, which are arranged opposite to each other and vertically connected to the base mounting frame. At least one set of servo electric cylinder power components installed on the side of the fixed section are driven and connected to the tilting section of the electric roller conveyor through a tilting connection mechanism fixedly installed on the side of the tilting section. At the bottom of the tilting section of the electric roller conveyor, a set of tilting shafts are sleeved on by an array of flanges, and the two ends of the tilting shafts are respectively mounted on the base mounting frame through a set of bearings with seats. Driven by the servo electric cylinder power components, the tilting section of the electric roller conveyor reciprocates around the tilting shafts in a circumferential direction.

[0007] Furthermore, the servo electric cylinder power assembly includes a servo motor and a servo electric cylinder. The bases of the servo motor and the servo electric cylinder are mounted on the base mounting bracket via an electric cylinder mounting bracket. The electric cylinder mounting bracket is fixedly connected to the servo electric cylinder base via a male-female hinge. The output shaft end of the servo electric cylinder is connected to the flipping connection mechanism via a ball-head fisheye assembly.

[0008] Furthermore, a sensor plate is installed on the side of the flip shaft, and a photoelectric detection component is installed on one side of the base mounting bracket.

[0009] Furthermore, a protective cover is connected to the outside of the servo electric cylinder power assembly and at the junction of the electric roller machine's fixed section and the electric roller machine's tilting section.

[0010] Furthermore, the base mounting frame includes a basic frame, at the corners of which are respectively provided two sets of electric cylinder mounting base fixing plates for connecting and fixing the electric cylinder mounting support, and two sets of buffer pads for supporting and buffering the fall of the fixed section of the electric roller machine.

[0011] Furthermore, at least one set of horizontal fixing section mounting blocks for connecting the bottom of the fixed section of the electric roller machine is provided inside the basic frame.

[0012] Furthermore, at least one set of bearing seat mounting plate for mounting the bearing with seat on the side of the flip shaft, photoelectric mounting bracket for mounting the photoelectric detection component, adjusting pad for adjusting the height and fixing of the base frame, and protective cover mounting bracket for mounting the protective cover are respectively provided on the side of the base frame.

[0013] In summary, the compact electric tilting linear roller conveyor proposed in this application has the following advantages:

[0014] 1. This application adopts a drive method of servo motor plus servo electric cylinder. Compared with the existing three-phase asynchronous geared motor, the turning angle control accuracy is higher and the overall structure of the conveyor line is more compact, which can effectively reduce the height of the conveying surface by about 150mm. At the same time, the overall thickness of the conveyor line in the horizontal state is smaller.

[0015] 2. Upon receiving a fire signal or manual control command, the servo electric cylinder can convert the rotational motion of the servo motor into linear motion, and pull up the turning section of the roller machine around the rotating shaft through the connecting mechanism. The turning angle can be precisely controlled and dynamically adjusted by the encoder of the servo motor.

[0016] 3. This application has a position detection photoelectric device at the end of the flipping shaft, which, together with the extension stroke of the servo electric cylinder, provides double protection for the flipping angle control, resulting in higher control efficiency.

Detailed Implementation

[0025] Example 1, such as Figure 1 and Figure 2 As shown, the compact electric tilting linear roller conveyor 3 described in this application is applied to a double-layer conveyor line. The double-layer conveyor line includes two superimposed upper conveyor line 6 and lower conveyor line 7, which are composed of two sets of platforms 2 and platform guardrails 1 as the base. A set of compact electric tilting linear roller conveyor 3 and platform tilting plate 5 are respectively arranged at the relative positions of the lower conveyor line 7.

[0026] In the event of an emergency such as a fire, the two sets of compact electric tilting linear roller conveyors 3 and platform tilting plates 5 are tilted by fire alarm signals or manual control commands to lower the fire shutter 4 vertically, thereby isolating and sealing the inner and outer conveying areas.

[0027] Since the platform flipping plate 5 needs to be flipped, and the vertical layer height between the upper conveyor line 6 and the lower conveyor line 7 is small, the compact electric flipping linear roller conveyor 3 described in this application is required to have a relatively compact overall structure, while having a small flipping space and a large flipping angle under the condition of limited flipping space. The following structural design scheme is adopted in this application.

[0028] The compact electric tilting linear roller conveyor includes an electric roller machine fixed section 1.1 and an electric roller machine tilting section 1.2, which are arranged opposite to each other and vertically connected to the base mounting frame 1.5; two sets of servo electric cylinder power assemblies 1.4 are installed on both sides of the electric roller machine fixed section 1.1, and are driven and connected to the electric roller machine tilting section 1.2 through a set of tilting connection mechanisms 1.10 fixedly installed on the side of the electric roller machine tilting section 1.2.

[0029] At the bottom of the electric roller mill's turning section 1.2, an array of flanges are fitted onto a set of turning shafts 1.9. The two ends of the turning shafts 1.9 are respectively mounted on the base mounting bracket 1.5 via a set of bearings with seats.

[0030] Driven simultaneously by two sets of servo electric cylinder power components 1.4, the electric roller machine's turning section 1.2 reciprocates around the turning shaft 1.9 in a circumferential direction.

[0031] When the two sets of electric roller conveyor tilting sections 1.2 tilt upwards respectively, the fire-fighting roller shutter 4 can fall vertically to close the inner and outer conveying areas.

[0032] To improve the safety of on-site operations, a protective cover 1.3 is connected to the outside of the two sets of servo electric cylinder power components 1.4 and the connection between the electric roller machine fixed section 1.1 and the electric roller machine tilting section 1.2, so as to enclose the servo electric cylinder power components 1.4 from the outside and prevent operators from touching the drive components and being injured.

[0033] The servo electric cylinder power assembly 1.4 includes a servo motor 1.7 and a servo electric cylinder 1.8. The bases of the servo motor 1.7 and the servo electric cylinder 1.8 are mounted on the base mounting bracket 1.5 via an electric cylinder mounting bracket 1.6. The electric cylinder mounting bracket 1.6 is fixedly connected to the base of the servo electric cylinder 1.8 via a male-female hinge to provide the necessary rotational connection to the servo electric cylinder 1.8 during the flipping action. The output shaft end of the servo electric cylinder 1.8 is connected to the flipping connection mechanism 1.10 via a ball joint fisheye assembly, thereby eliminating the non-parallel torque caused by component processing or assembly accuracy issues.

[0034] Driven by the servo motor 1.7, the servo electric cylinder 1.8 converts the rotational motion of the servo motor 1.7 into linear motion. Its output shaft acts on the flipping connection mechanism 1.10 and transmits pushing and pulling force to the flipping section 1.2 of the electric roller machine through the flipping connection mechanism 1.10, so that the flipping section 1.2 of the electric roller machine flips around the flipping shaft 1.9 to flip up or down.

[0035] To further improve the accuracy of the flipping control and achieve dual monitoring, a sensor plate is installed on the side of the flipping shaft 1.9, and a photoelectric detection component 1.11 is installed on one side of the base mounting bracket 1.5. The photoelectric detection component 1.11 is used to detect and feedback the rotation angle of the sensor plate, and to determine the flipping angle and position of the flipping shaft 1.9, i.e. the flipping section 1.2 of the electric roller machine, through the sensor plate.

[0036] The base mounting bracket 1.5 is used to connect the above-mentioned components and serve as a machine frame to adjust the overall height of the connected electric roller machine. It includes a base frame 1.5.1, and at the corners of the base frame 1.5.1, there are two sets of electric cylinder mounting base fixing plates 1.5.8 for connecting and fixing the electric cylinder mounting support 1.6, and two sets of buffer pads 1.5.3 for supporting and buffering the fall of the fixed section 1.1 of the electric roller machine.

[0037] Inside the basic frame 1.5.1, there is at least one set of horizontal fixing section mounting blocks 1.5.4 for connecting the bottom of the electric roller machine fixing section 1.1. The horizontal fixing section mounting blocks 1.5.4 also act as pads to compensate for the vertical installation height of the electric roller machine fixing section 1.1.

[0038] At least one set of bearing seat mounting plate 1.5.2 for mounting the bearing seat on the side of the base frame 1.5.1, a photoelectric mounting bracket 1.5.5 for mounting the photoelectric detection component 1.11, an adjusting pad 1.5.6 for adjusting and fixing the height of the base frame 1.5.1, and a protective cover mounting bracket 1.5.7 for mounting the protective cover 1.3 are respectively provided on the side of the base frame 1.5.1.

[0039] The embodiments described above, in conjunction with the accompanying drawings, are merely preferred solutions for achieving the objectives of this utility model. Those skilled in the art can draw inspiration from this and directly derive other alternative structures that conform to the design concept of this utility model. Other structural features derived therefrom should also fall within the scope of the solutions described in this utility model.
