Technical Field

[0001] The present invention relates to the technical field of stacking machinery, and in particular to a stacking machine and a ceiling rail guide device thereof. Background Art

[0002] With the rapid development of logistics and warehousing, stackers are increasingly used in automated warehouses. Stackers mainly include cargo platforms, columns, lower beams, travel drive components, lifting drive components, ceiling rail components, and floor rail components, among which the ceiling rail component is one of the important components; and the guide device, as a part of the ceiling rail component, has a guide wheel that is often worn during use due to processing, manufacturing or installation errors, resulting in a gap between the guide wheel and the ceiling rail during travel, affecting the normal operation of the stacker.

[0003] At present, the guide wheel is generally fixed to the ceiling rail bracket by two or more bolts. In order to solve the problems caused by processing, manufacturing and installation errors, the only method that can be adopted is to open holes for fixing the guide wheel on the ceiling rail bracket during installation. However, there is currently no good way to solve the problem of wear during use, which leads to a gap between the guide wheel and the ceiling rail during walking. Summary of the invention

[0033] In order to better illustrate the present invention, the present invention is further described in detail below with reference to the accompanying drawings.

[0034] Example 1

[0035] A stacker overhead rail guide device, comprising:

[0036] like Figure 1 , 2 As shown, a fixing plate 100 and an axle seat 300 for connecting a guide wheel 200;

[0037] like Figure 3 As shown, a first virtual circle 110 is provided on the fixing plate 100, at least two first mounting holes 111 are provided on the circumference of the first virtual circle 110, and a second mounting hole 112 is provided at the center of the first virtual circle 110;

[0038] The wheel axle seat 300 is provided with at least two connection holes 301;

[0039] When connecting, the two connecting holes 301 correspond to the first mounting hole 111 and the second mounting hole 112 respectively. A connecting member 500 passes through one connecting hole 301 and the first mounting hole 111, and another connecting member 500 passes through another connecting hole 301 and the second mounting hole 112, thereby connecting the wheel axle seat 300 and the fixing plate 100 together.

[0040] Specifically, Figure 3 , 4 As shown, the center of one of the first mounting holes 111 and the center of the second mounting hole 112 are on a first straight line 130 , the first straight line 130 is parallel to the moving direction of the stacker, and the other first mounting holes 111 are symmetrically arranged on both sides of the first straight line 130 .

[0041] In this embodiment, a first mounting hole is arranged on a first straight line parallel to the traveling direction of the stacker, and a plurality of first mounting holes are symmetrically arranged on both sides of the first straight line, so that the wheel axle seat can be adjusted both inwardly and outwardly.

[0042] Specifically, the connecting member 500 is a bolt, the first and second mounting holes 111 and 112 are threaded holes, and the connecting hole 301 is a through hole.

[0043] It should be noted that, in this embodiment, the connecting member 500 can also be a bolt and a nut, and the first and second mounting holes 111 and 112 can also be through holes. After the bolt passes through the first and second mounting holes, the nut is connected to one end of the bolt to fix the wheel axle seat and the fixing plate.

[0044] Specifically, Figure 5 As shown, the overhead rail guide device further includes a bearing 600 and a guide wheel 200 ; the guide wheel 200 is sleeved on the wheel axle seat 300 , and the bearing 600 is arranged between the guide wheel 200 and the wheel axle seat 300 .

[0045] The overhead rail guide device of the stacker of this embodiment is provided with a first virtual circle on the fixing plate, at least two first mounting holes are provided on the circumference of the first virtual circle, and a second mounting hole is provided on the circumference of the first virtual circle; when connecting, a connecting member is passed through the connecting hole and the first mounting hole on the axle seat, and another connecting member is passed through the connecting hole and the second mounting hole on the axle seat, so that the axle seat and the fixing plate are connected together; Figure 6As shown, when the guide wheel needs to be moved inward or outward, it is only necessary to remove the connecting piece passing through the first mounting hole, and then pass it through another first mounting hole, so that the wheel axle seat drives the guide wheel to swing inward or outward at a certain angle with the center of the second mounting hole, so that when a gap is generated between the guide wheel and the ceiling rail, the operator can adjust the position of the guide wheel conveniently and quickly.

[0046] It should be noted that when moving the wheel axle seat, the connecting piece in the first mounting hole should be completely removed, and the connecting piece fixed at the second mounting hole should also be loosened.

[0047] exist Figure 6 The axle seat 300 at the top is in a normal state, and the axle seat 300 at the bottom is in a state of being offset to the outside of the ceiling rail.

[0048] This embodiment also provides a stacker, which includes: a travel drive component, a lifting drive component, and a ceiling rail component.

[0049] Wherein, the above-mentioned ceiling rail guide device is arranged inside the ceiling rail component.

[0050] Example 2

[0051] This embodiment is basically the same as Embodiment 1, with the main difference being:

[0052] like Figure 7 , 8 As shown, the fixing plate 100 is provided with a plurality of the second mounting holes 112;

[0053] Among them, several second mounting holes 112 are arranged on the circumference of a second virtual circle 120, the center of the second virtual circle 120 and the center of the first virtual circle 110 are on the first straight line 130, and the center of the second virtual circle 120 is arranged at the center of the first mounting hole 111 on the first straight line 130.

[0054] The overhead rail guide device of the stacker of the present embodiment sets a second virtual circle with the center of the first mounting hole on the first straight line as the center, and arranges multiple second mounting holes on the circumference of the second virtual circle, so that the operator can remove a connecting part at will to adjust the position of the guide wheel; compared with Example 1, it is necessary to find the connecting part connected to the first mounting hole and then remove the connecting part to complete the adjustment, which further facilitates the actual operation.

[0055] Preferably, a plurality of the second mounting holes 112 are symmetrically arranged on both sides of the first straight line 130 .

[0056] Preferably, the lines connecting the centers of two adjacent first mounting holes 111 and the center of the first virtual circle 110 form a first angle α;

[0057] Lines connecting the centers of two adjacent second mounting holes 112 and the center of the second virtual circle 120 form a second angle β;

[0058] The first angle α is not equal to the second angle β.

[0059] For example, the first angle α is 5° and the second angle β is 10°. When the connecting hole is adjusted from corresponding to the first mounting hole on the first straight line to corresponding to an adjacent first mounting hole, the swing angle of the axle seat is 5°; and when the connecting hole is adjusted from corresponding to the second mounting hole on the first straight line to corresponding to an adjacent second mounting hole, the swing angle of the axle seat is 10°; because the swing angle is larger, the offset distance is also larger. When the operator needs to offset a smaller distance at a time, the connecting hole can be made to correspond to a different first mounting hole, and when a larger distance is needed at a time, the connecting hole can be made to correspond to a different second mounting hole. Therefore, the operator has a variety of adjustment methods to choose from.

[0060] It should be noted that, in this embodiment, the first angle α and the second angle β do not mean limitations on the present invention, and each first angle α or each second angle β may not be equal, that is, the distance between two adjacent first mounting holes may be larger or smaller, and the same applies to the second mounting holes.
