Description
Technical Field
[0001] The utility model relates to the technical field of coil transfer, in particular to an anti-toppling device for a material taking trolley. Background Art
[0002] After the metal coil is produced, it is necessary to use a V-shaped surface trolley to remove the coil from the cross arm, and then transfer it to the packaging production line for automatic packaging. Since the metal coil is prone to topple when placed on the V-shaped surface of the trolley, to solve this problem, the traditional method is mainly to set slots for inserting the retaining rods along the length direction on both sides of the trolley, and the retaining rods are inserted manually, which is time-consuming and laborious, with low automation, and cannot adapt to coils of different sizes. Currently, there are special devices on the market for limiting the metal coil, mostly in the form of a piano key structure, which consists of a group of interlaced piano key type clamping plates, installed directly above the trolley, and driven by an oil cylinder to press down. The piano key type clamping plates will naturally insert into the gaps of the coil, thus preventing the metal coil from toppling. However, the above structure still has the following defects: (1) It cannot be adaptively adjusted according to coils of different sizes, and manual intervention is required during adjustment, with still relatively low automation; (2) It is a downward pressing structure installed directly above, and it is impossible to load and unload materials from directly above; (3) The structure design is cumbersome and complex, with high costs and is not conducive to maintenance. Summary of the Utility Model
[0003] The technical problem to be solved by the utility model is: to overcome the deficiencies in the prior art and provide an anti-toppling device for a material taking trolley with a simple structure design, low manufacturing cost, high automation, easy maintenance, and does not affect the loading and unloading of coils from directly above.

Specific Embodiments
[0030] The present utility model will now be further described in conjunction with the accompanying drawings. These drawings are all simplified schematic views, only illustrating the basic structure of the present utility model in a schematic manner, and therefore only showing the components related to the present utility model.
[0031] Such as Figure 1 and Figure 3As shown in the figure, an anti-toppling device for a material handling trolley includes a chassis 100, a sliding plate 200, a fixed stop rod 300, a movable stop rod 400, a sliding seat 500, a first driving assembly 600, and a second driving assembly 700. The chassis 100 is inclined and installed on one side of the material handling trolley. The sliding plate 200 is arranged horizontally and is slidably installed at the top of the chassis 100. The bottom end of the fixed stop rod 300 is connected to the right end of the sliding plate 200. The bottom end of the movable stop rod 400 is slidably connected to the left part of the sliding plate 200 through the sliding seat 500. The first driving assembly 600 is installed in the middle of the chassis 100 to drive the sliding plate 200 to move longitudinally. The second driving assembly 700 is distributed on the sliding plate 200 and the sliding seat 500 to drive the sliding seat 500 to move horizontally. By driving the sliding plate 200 to move longitudinally through the first driving assembly 600, the fixed stop rod 300 and the movable stop rod 400 can limit the coil from the side, without occupying the space directly above the coil, and without affecting the loading and unloading of the coil from directly above. Combining with the second driving assembly 700 to drive the sliding seat 500 to move horizontally, the distance between the fixed stop rod 300 and the movable stop rod 400 can be automatically adjusted to achieve adaptive adjustment for coils of different sizes. The structure design is simple, the manufacturing cost is low, the degree of automation is high, and it is convenient for maintenance. Specifically, the chassis 100 is connected to the material handling trolley through a mounting plate; the bottom end of the sliding plate 200 is connected to the top end of the chassis 100 through a slide rail-slider structure to ensure the stability of the longitudinal movement of the sliding plate 200; the bottom end of the sliding seat 500 is also connected to the top end of the sliding plate 200 through a slide rail-slider structure; the fixed stop rod 300 and the movable stop rod 400 are both inclined relative to the chassis 100 and are in a "7" shape, such a design ensures the limiting effect. It should be noted that this device can be installed on both sides of the material handling trolley according to actual needs.
[0032] As Figure 1 and Figure 2 shown in the figure, a sensor 800 is installed at one end of the sliding seat 500 close to the material handling trolley, and proximity switches 900 are correspondingly arranged on the inner sides of the bottom ends of the fixed stop rod 300 and the movable stop rod 400. Through the setting of the sensor 800, when the material handling trolley picks up materials, it can accurately move to the picking position according to the detection signal. Combining with the setting of the proximity switches 900, the movable stop rod 400 can accurately move to the end face of the coil according to the actual width of the coil, further improving the degree of automation.
[0033] As Figure 1 and Figure 2As shown in the figure, the first driving assembly 600 includes a lead screw 610, a nut block 620, and a first motor 630. The lead screw 610 is disposed between the chassis 100 and the slide plate 200. The lead screw 610 is longitudinally arranged, and its two ends are respectively rotatably connected to the chassis 100. The nut block 620 is threadedly sleeved on the lead screw 610 and is connected to the middle part of the bottom end of the slide plate 200. The first motor 630 is installed on one side of the chassis 100 away from the material handling cart, and its output end is drivingly connected to the lead screw 610. Specifically, the two ends of the lead screw 610 are respectively connected to the chassis 100 through mounting seats; the output end of the first motor 630 is connected to the end of the lead screw 610 away from the material handling cart through a chain and sprocket structure. The first motor 630 drives the lead screw 610 to rotate, which is then converted into the axial movement of the nut block 620, thereby realizing the longitudinal movement of the slide plate 200.
[0034] As Figure 1 and Figure 2 shown in the figure, the second driving assembly 700 includes a rack 710, a second motor 720, and a gear 730. The rack 710 is disposed between the sliding seat 500 and the slide plate 200. The rack 710 is longitudinally arranged and is installed on the slide plate 200. The body of the second motor 720 is vertically installed on the sliding seat 500, and its output end is connected to the gear 730. The gear 730 meshes with the rack 710. The second motor 720 drives the gear 730 to rotate. Due to the meshing of the gear 730 and the rack 710, the sliding seat 500 is driven to move horizontally.
[0035] As Figure 1 shown in the figure, in order to avoid rigid contact when the fixed stop bar 300 and the movable stop bar 400 limit the coiled material, nylon plates 1000 are respectively installed on the relative inner sides of the fixed stop bar 300 and the movable stop bar 400.
[0036] As Figure 1 and Figure 2 shown in the figure, first limit plates 1100 are respectively installed on the front and rear sides of the chassis 100 to mechanically limit the maximum moving stroke of the slide plate 200. A second limit plate 1200 is installed on the slide plate 200. The second limit plate 1200 is respectively arranged on the left and right sides of the rack 710 to mechanically limit the maximum moving stroke of the sliding seat 500.
[0037] As Figure 2 shown in the figure, first signal devices 1300 are respectively installed at the front and rear ends of the chassis 100 to realize the intelligent limit of the moving stroke of the slide plate 200. A second signal device 1400 is installed at the left end of the sliding seat 500 to realize the intelligent limit of the moving stroke of the sliding seat 500.
[0038] After the cross arm 1500 is ready for the coil stock, the material fetching trolley moves towards the coil stock. At this time, the fixed stop bar 300 and the movable stop bar 400 are farthest from the material fetching trolley, that is, the slide plate 200 is located at the end of the chassis 100 away from the material fetching trolley, and the distance between the fixed stop bar 300 and the movable stop bar 400 is the farthest, that is, the slide seat 500 is located at the end of the slide plate 200 away from the coil stock, as Figure 4 shown. During the process of the material fetching trolley moving towards the coil stock, when the inductor 800 detects the disappearance of the coil stock signal, after a delay for a period of time, the controller (not shown in the figure) stops the material fetching trolley. At this time, the material fetching trolley is located at the material fetching position, as Figure 5 shown. Then the controller starts the first driving assembly 600 to drive the slide plate 200 to move towards the coil stock until the fixed stop bar 300 and the movable stop bar 400 reach both side ends of the coil stock, as Figure 6 shown. After reaching the position, the controller starts the second driving assembly 700 to drive the slide seat 500 to move towards the coil stock according to the actual width of the coil stock, as Figure 7 shown. When the proximity switch 900 on the movable stop bar 400 detects the end face of the coil stock, it stops, as Figure 8 shown. Finally, the material fetching trolley is lifted, and after the material fetching trolley finishes fetching the material, it is transported away, as Figure 9 and Figure 10 shown.

It cannot be used to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
