Below with reference to Fig. 1-Fig. 2 description according to 1 speed control of truck for truck group 10 of the utility model embodiment
Device.As Figure 1-Figure 2, include: according to 1 speed control unit of truck for truck group 10 of the utility model embodiment
At least two limit switches and triggering item.
Truck group 10 may include multilayer truck 1, such as truck group 10 can be the double-deck truck 1, and at least two limits are opened
Pass can be set in the bottom of each truck 1 of truck group 10, and optionally, two limits can be set in the bottom of each truck 1
Switch, two limit switches are located on the longitudinal axis of truck 1 and time interval distribution, and certainly, the bottom of truck 1 can also be set
Limit switch there are four setting, four limit switches are located at the two sides of the bottom of truck 1 and time interval is opened, and are located at front
Two limit switches are horizontally aligned, and are horizontally also aligned positioned at subsequent two limit switches.
Triggering item fixes on the ground, and triggering item may include: preceding triggering item 801 and rear triggering item 802 (in such as Fig. 2
Shown in front-rear direction), preceding triggering item 801 and rear triggering item 802 are opposite with the operating position of truck 1 and charging position respectively
It answers, limit switch carries out different movements respectively from the accessible merging control truck 1 of matching of triggering item to change the speed of truck 1
Degree.
It is understood that being mounted with two limit switches on truck 1, for detecting the walking position of truck 1, and feed back
PLC (Programmable Logic Controller programmable logic controller (PLC)) position signal is given, for slowing down and stopping.
When PLC is connected to 1 signal in place of truck, PLC is issued to suction cup carrier can be with the instruction of suction, to draw the work of plate
Make, when not having signal, suction cup carrier cannot work, thus protect machinery equipment using safe.
According to 1 speed control unit of truck for truck group 10 of the utility model embodiment, by being set on truck 1
Multiple limit switches are set, it is made to be engaged with the triggering item for being fixed on ground, so that the walking speed of truck 1 can be effectively controlled
Degree ensures production safety, while convenient for the production under the conditions of multilayer truck 1.
By taking two limit switches as an example, two limit switches are spaced apart in the length direction of truck 1.Further, it limits
Bit switch may include: the first limit switch 15 and the second limit switch 16, in the first limit switch 15 and the second limit switch
16 respectively with triggering item contact when, truck 1 carries out different movements, in this way, can to truck 1 realize slow down step by step, the life of equipment
It is higher to produce safety.
Optionally, during truck 1 is moved to charging position by operating position, the first limit switch 15 and rear triggering
When item 802 contacts, truck 1 carries out the first movement, and when the second limit switch 16 is contacted with rear triggering item 802, truck 1 carries out second
Movement, it should be noted that the first movement here is that truck 1 slows down, and the second movement is that truck 1 brakes.
That is, during truck 1 is moved to charging position by operating position, the first limit switch 15 first with
Triggering item 802 contacts afterwards, and the motor 2 of limit switch triggering at this time slows down, and so that the speed of truck 1 is gradually lowered, continues to travel, the
Two limit switches 16 start to contact with rear triggering item 802, and the motor 2 of limit switch triggering at this time brakes, and make 1 stop motion of truck,
So far, truck 1 outputs completion, consequently facilitating subsequent charging work.
Correspondingly, during truck 1 is moved to operating position by charging position, the second limit switch 16 and preceding triggering
When item 801 contacts, truck 1 carries out the first movement, and when the first limit switch 15 is contacted with preceding triggering item 801, truck 1 carries out second
Movement, it should be noted that the first movement here is that truck 1 slows down, and the second movement is that truck 1 brakes.
That is, during truck 1 is moved to operating position by charging position, the second limit switch 16 first with
Preceding triggering item 801 contacts, and the motor 2 of limit switch triggering at this time slows down, and so that the speed of truck 1 is gradually lowered, continues to travel, the
One limit switch 15 starts to contact with preceding triggering item 801, and the motor 2 of limit switch triggering at this time brakes, and makes 1 stop motion of truck,
So far, 1 return of truck, is parked in operating position, convenient for the normal production work of follow-up equipment.
Optionally, limit switch (such as the first limit switch 15 and the second limit switch 16) can be communicated with motor 2, as a result,
When triggering item 801 and rear triggering item 802 before the first limit switch 15 and the second limit switch 16 touch, signal can be transmitted
Give PLC (not shown), PLC, which is received, can control after signal motor 2 the corresponding movement such as slowed down, braked, to grasp
Facilitate, precise control.
In further embodiments, speed control unit can also include: baffle 901, and baffle 901 can be set in truck
1 front, and flexible block 902 can be set on baffle 901, flexible block 902 is to being equipped with the direction of truck 1 from baffle
901 protrude above, and when truck 1 returns to operating position from charging position, the front end of truck 1 can be resisted against on flexible block 902, by
This, in 1 return of truck, flexible block 902 can be such that the brake of truck 1 is buffered, to keep 1 return of truck steady.
Further, speed control unit can also include: buffer 903, and buffer 903 is also disposed on baffle 901
And it is identical as the extending direction of flexible block 902, and the rear end of buffer 903 exceeds the rear end of flexible block 902, it is sharp as a result,
First the return of truck 1 is buffered with buffer 903, flexible block 902 is recycled to buffer revert action further progress,
The return of truck 1 can be made steady, advantageously ensure that the production safety of equipment.
In conclusion according to 1 speed control unit of truck for truck group 10 of the utility model embodiment, by
Multiple limit switches are set on truck 1, so that it is engaged with the triggering item for being fixed on ground, so that truck 1 can be effectively controlled
The speed of travel, ensure production safety, while convenient for the production under the conditions of multilayer truck 1.
Especially working as truck group 10 is multilayer truck 1, such as when the double-deck truck 1, upper layer truck 1 is controlled by PLC, needs to produce
When plate on upper layer truck 1, upper layer truck 1 is placed in operating position, when needing to produce the plate on lower layer's truck 1, upper layer material
Vehicle 1 is outputed automatically, and the plate on lower layer's truck 1 can be drawn by suction cup carrier at this time, easy to operate, high production efficiency.
The utility model additionally provides a kind of truck group 10, which includes the above-mentioned truck for truck group 10
1 speed control unit, to have many advantages, such as 1 speed control of truck convenience, production safety.
