Description

Technical Field

[0001] This utility model relates to the field of automated sorting technology in logistics, and in particular to a sorting trolley based on a linear motor. Background Technology

[0002] In express logistics sorting centers, automated sorting equipment has become a core component. Among them, the circular cross-belt sorting machine is widely used due to its high efficiency and accuracy. Traditional sorting carts are mostly driven by a centralized motor with a transmission belt, or by a rotary motor, which has problems such as complex structure, difficult maintenance, and low control precision.

[0003] In recent years, linear motor technology has been introduced into the sorting field. By setting a secondary board at the bottom of the trolley, it interacts with the primary linear motor mounted on the sorting machine base to directly generate driving force, realizing independent and precise driving of the trolley. However, the power supply problem of this sorting trolley has become a technical challenge. Traditional solutions mostly use wireless power supply or battery power supply. Wireless power supply has problems such as low efficiency, high cost, and electromagnetic interference; while battery power supply requires frequent charging or replacement, affecting continuous operation capability and increasing maintenance costs.

The current collector brush is rotatably connected to one end of the rotating frame, and a limiting foot is provided at the other end of the rotating frame. An elastic element is provided between the rotating frame and the mounting base.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0024] Example 1

[0025] Reference Figure 1 This is the first embodiment of the present invention. This embodiment provides a sorting trolley based on a linear motor, including a mounting frame 1. Roller sets 11 are fixedly connected to both ends of the mounting frame 1. An electric roller 2 is installed at one end of the mounting frame 1, and a driven roller 3 is installed at the other end. A belt 5 for carrying goods is sleeved on the electric roller 2 and the driven roller 3. A secondary plate 8 is fixedly provided at the bottom of the mounting frame 1.

[0026] Mounting plates 4 are fixedly connected to both sides of the mounting bracket 1, and a current collector 6 is mounted on at least one mounting plate 4;

[0027] The current collector 6 includes a mounting base 61, a rotating frame 62, and a current collector brush 63. The mounting base 61 is fixedly connected to the mounting plate 4, the rotating frame 62 is rotatably connected to the mounting base 61, and the current collector brush 63 is rotatably connected to one end of the rotating frame 62. The other end of the rotating frame 62 is provided with a limiting foot 64. An elastic element 65 is provided between the rotating frame 62 and the mounting base 61. The elastic force of the elastic element 65 acts on the rotating frame 62, so that the limiting foot 64 tends to remain in contact with the mounting base 61, thereby limiting the initial lowest position of the current collector brush 63.

[0028] The inner cavity of the mounting frame 1 is fixedly connected to a slide bed 7, and the upper surface of the slide bed 7 is in contact with the inner side of the belt 5; the inner cavity of the mounting frame 1 is fixedly connected to a slide bed 7; there are multiple sets of mounting plates 4, and each set of mounting plates 4 is located on both sides of the belt 5; the elastic element 65 is specifically a spring; the rotational connection axis of the collector brush 63 is parallel to the rotational connection axis of the rotating frame 62.

[0029] It should be noted that the roller sets 11 at both ends of the mounting frame 1 roll on the base track. One end of the mounting frame 1 is equipped with an electric roller 2, and the other end is equipped with a driven roller 3. The belt 5 is sleeved on the electric roller 2 and the driven roller 3 to form the bearing surface of the sorting trolley. In order to prevent the belt 5 from sinking when carrying heavy objects, a slide bed 7 is fixedly installed in the inner cavity of the mounting frame 1. The upper surface of the slide bed 7 contacts the inner side of the belt 5 to provide support for it.

[0030] The bottom of the mounting frame 1 is fixed with a secondary plate 8 by bolts. When multiple sorting carts are connected end to end by the connecting plate to form a circular sorting line and installed on the base (not shown in the figure), the secondary plate 8 will have an electromagnetic interaction with the primary of the linear motor (not shown in the figure) installed on the base, thereby driving the sorting cart to move along the linear motor track.

[0031] On both sides of the mounting frame 1, multiple sets of mounting plates 4 are fixedly connected. The mounting plates 4 are located on the outside of the belt 5 and serve as protection and installation support. On one set of mounting plates 4, a current collector 6 is installed.

[0032] The current collector 6 includes a mounting base 61 fixedly connected to the mounting plate 4. A rotating frame 62 is rotatably connected to the mounting base 61 via a pin. One end of the rotating frame 62 is rotatably connected to a current collector brush 63, and the other end of the rotating frame 62 is bent downward to form a limiting foot 64. A spring is installed between the rotating frame 62 and the mounting base 61 as an elastic element 65. Under the action of the spring, one end of the rotating frame 62 is subjected to a downward force, causing the limiting foot 64 to press tightly against the mounting base 61. This state is the initial state of the current collector, at which time the current collector brush 63 is maintained at a certain initial lowest position.

[0033] In use, when the sorting cart is installed on the sorting line, the installation height of the externally powered sliding contact line 9 is higher than the initial lowest position of the collector brush 63. Therefore, during the installation process, the sliding contact line 9 will contact the collector brush 63 from below and push it upward. The lifting of the collector brush 63 will force the rotating frame 62 to overcome the spring force and rotate around the pin shaft, thereby causing the limit foot 64 to disengage from the mounting base 61. At this time, the spring force is converted into a continuous counterclockwise return torque on the rotating frame 62. This torque is eventually transmitted to the collector brush 63, which manifests as a continuous upward pressure, forcing the collector brush 63 to always press tightly against the lower surface of the sliding contact line 9, thereby achieving stable and reliable conductive contact.

[0034] The electrical energy obtained from the sliding contact line 9 by the current collector 6 is transmitted to the electric roller 2, which drives it to rotate, thereby driving the belt 5 to move and complete the sorting and unloading of goods.

[0035] In summary, the power supply method through contact between the current collector 6 and the sliding contact line offers higher energy transmission efficiency and lower cost compared to wireless power supply. It also eliminates electromagnetic interference issues and provides a continuous and stable power supply to the sorting cart. By utilizing the spring force and the rotation of the rotating frame 62, the current collector brush 63 is lifted upwards by the sliding contact line after installation and remains in close contact with the sliding contact line under the pressure of the spring. This automatically compensates for installation errors and deformations of the sliding contact line, ensuring reliable and continuous contact.

[0036] Importantly, the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
