Referring to Figures 1A, 1B, 2, 3A, 3B, and 3C, the present invention is a storage handling system with a booster device, which includes: a storage unit 10 having at least two storage devices 11, A lifting channel 12, at least one booster fixing portion 13 and a plurality of lifting rail portions 14. Each storage device 11 has a plurality of storage spaces 111. The lifting channel 12 is between the two storage devices 11. The at least one booster fixing part 13 is arranged on one of the at least two storage devices 11 and faces the lifting channel 12. The plurality of lifting rail parts 14 are respectively correspondingly arranged on the at least two storage devices 11.

A conveying device 20 has a plurality of driving wheels 21, a supporting portion 22 and at least one first clutch portion 23. When the plurality of driving wheels 21 contact the corresponding plurality of lifting rail parts 14, the conveying device 20 and the lifting channel 12 can move up and down relative to each other. And can move to at least a first height H1, a second height H2, and a third height H3; the first height H1 is lower than the second height H2, and the second height H2 is lower than the third height H3 .

At least one booster device 30 (in Figure 1B, the corresponding coefficients of the booster device fixing portion 13 and the booster device 30 in Figure 1A are omitted as at least one group, which is first described), which is fixed to the At least one booster fixing part 13. The at least one booster device 30 has a second clutch portion 31 and a booster supply portion 32 (for example, the first embodiment shown in Figs. 4A, 4B, and 4C, or the first embodiment shown in Figs. 5A and 5B, for example. Second embodiment); The second clutch portion 31 can be relatively separated from the first clutch portion 23 / relatively combined.

Thereby, when the conveying device 20 moves upward from the first height H1 to the second height H2, the first clutch portion 23 and the second clutch portion 31 automatically change from relative disengagement to relative coupling. The booster supply part 32 provides a boost for moving the conveying device 20 upward, and the conveying device 20 can at least continuously move up to the third height H3 (of course, it can be higher).

And when the conveying device 20 moves down from the third height H3 to the second height H2, the first clutch part 23 and the second clutch part 31 automatically change from relative coupling to relative disengagement. The boost supply part 32 does not contact the conveying device 20.

In practice, the second clutch portion 31 may have a guide groove 31A, a guide wall portion 31B, a slider 31C, and a turntable portion 31D. The sliding block 31C is connected to the booster supply part 32 and can slide relative to the guide groove 31A. The turntable portion 31D has a pivoting spindle 311, a blocking portion 312 and a clutch groove 313. The pivoting spindle 311 is pivoted on the slider 31C, the blocking portion 312 can slide relative to the guide wall portion 31B, and the clutch groove 313 is used to interact with the first clutch portion 23 To switch between relative separation/relative combination.

The boost supply unit 32 may have the following embodiments:

[a] First embodiment: referring to Figures 4A, 4B, and 4C, the booster supply 32 may be an elastic element. And one end is connected to the guide groove 31A corresponding to the opposite side of the slider 31C, and the other end is connected to the slider 31C. When the first clutch portion 23 and the second clutch portion 31 (more specifically, the clutch groove 313) are relatively combined, they are used to provide the conveying device 20 with a boost to move upward.

Furthermore, when the booster supply part 32 is an elastic element, the storage handling system with booster device may further include a buffer element 40. When the slider 31C moves to contact the buffer element 40, it is used to assist control The conveying device 20 does not rise too fast due to assisting.

[b] Second embodiment: referring to Figures 5A and 5B, the booster supply portion 32 can be at least one counterweight pulley assembly, and each counterweight pulley assembly can include a counterweight 321, a cable 322, and A pulley control group 323.

Of course, the greater the number of the power-assisting device fixing parts 13 and the power-assisting device 30 (the number increases or decreases within the scope of the protection of this case), the better the power-assisting effect.

Regarding the process of transforming the first clutch part 23 and the second clutch part 31 from relative disengagement to relative coupling, the process is as follows: Referring to Figure 4A, when the conveying device 20 is located at the first height H1, the blocking portion 312 of the second clutch portion 31 corresponds to the bottom of the guide groove 31A, and the clutch groove 313 is diagonally downward and faces the first A clutch part 23. And when the conveying device 20 rises from the first height H1 to the second height H2 (the rise and fall are known technologies, which are not the focus of this case, and will not be repeated), the first clutch part 23 is exactly corresponding to the clutch groove 313 (Refer to Fig. 5A for reference). Then, as shown in Fig. 4B, the conveying device 20 continues to rise, the first clutch part 23 slides into the clutch groove 313, and pushes the turntable part through the clutch groove 313 31D, the turntable portion 31D rotates with the pivoting shaft 311 as the axis, and the blocking portion 312 then rotates to be parallel to the guiding wall portion 31B. The booster supply portion 32 provides boost for the upward movement of the conveying device 20, and the blocking portion 312 starts to move relative to the guide wall portion 31B, so that the conveying device 20 can be raised to at least the third height H3 ( (As shown in Figures 4C and 5B).

The key point of this case is that the conveying device 20 has a considerable weight (assumed to be 500 kg) in order to be firm, plus it needs to carry heavy objects (assumed to be 800 kg), which is quite heavy (1300 kg) in total. The plurality of driving wheels 21 of the conveying device 20 and the plurality of lifting rails 14 can move relatively smoothly. In this case, the first clutch portion 23 and the second clutch portion 31 are designed for the conveying device 20 and the boosting device 30 to be able to move relatively smoothly. Quickly change between relative disengagement/relative bonding. Further, when relatively combined, the booster device 30 can generate a boost for the conveying device 20 to lift the conveying device 20, reduce the load of the relative engagement and transmission of the plurality of driving wheels 21 and the plurality of lifting rails 14, and enable smooth relative movement.

The advantages and effects of the present invention are as follows:

[1] The automatic clutch is quite convenient during the lifting process. The first clutch part and the second clutch part corresponding to each other are arranged between the conveying device and the boosting device. When the conveying device rises to a predetermined height (for example, from the first height to the second height), the first clutch part automatically changes from the relative disengagement to the relative combination with the second clutch part, and then when the conveying device drops to the predetermined height ( For example, if it descends from the third height to the second height), the first clutch part automatically resets to the second clutch part from the relative combination to the relative separation. The action process does not need to be controlled separately, which is quite convenient. Therefore, the automatic clutch during the lifting process is quite convenient.

[2] The lifting assist of the booster can reduce the load loss of the driving wheel. The present invention is provided with a booster device, which can generate boost during the lifting process of the conveying device, and assist the lifting of the conveying device, effectively reducing the heavy load of the driving wheel due to the load, and the wear when engaging the lifting rail part. Therefore, the lifting assist of the booster can reduce the load loss of the driving wheel.

[3] The mechanical clutch device does not require electricity and is quite energy-saving. In this case, the first clutch part and the second clutch part are both mechanical, and there is no need for electricity during frequent clutch actions. Therefore, the mechanical clutch device does not require electricity and is quite energy-saving.

The above is only a detailed description of the present invention with a preferred embodiment, and any simple modifications and changes made to the embodiment will not depart from the spirit and scope of the present invention.
