In practical applications, such as Fig. 1, the present invention is set for two conveyer belts or crawler belt in the machinery for transmitting an object
Standby upper application, and operation can be operated alone in two conveyer belts or crawler belt.These objects can be automobile, material storage-transportation case or material
The objects such as pallet.
Detection sensor is respectively set at the inner side and outer side position of each conveyer belt(It is passed including infrared opposite-radiation tubular type
Sensor or ultrasonic sensor etc.), a pair of of detection sensor of crooked detection that a1, a2 are conveyer belt A, b1, b2 are conveyer belt B
A pair of of detection sensor of crooked detection.A1, a2, b1, b2 detection sensor are respectively placed in mounting bracket, the peace of a1 and b1
Higher than the object of transmission, the installation site of a2 and b2 is generally at the intermediate position of two conveyer belts and with conveyer belt holding position
One horizontal plane, specific installation site regards conveyer belt and transmits the size decision of object, according to the ruler of conveyer belt and transmission object
It is very little, select the detecting distance of detection sensor.With occur object it is crooked when, detection light or sound wave between detection sensor can
Reliably be blocked and do not influence conveyer belt operation and object above be transmitted as criterion, a1, a2, b1, b2 scheme of installation are such as
Shown in Fig. 2, Fig. 3.
When the object on conveyer belt is in transmit process, when the sides A occur crooked, as shown in figure 4, object is in transmit process
In, first occlusion detection sensor a1, a2, i.e. detection sensor a1, a2 act output signal, at this time can be defeated by detection device
Going out signal, keeps conveyer belt A out of service, conveyer belt B continues to run until that detection sensor b1, b2 is blocked, as shown in figure 5,
I.e. detection sensor b1, b2 acts output signal, at this time by detection device output signal, so that conveyer belt A is run, conveyer belt B
It continues to run so that the sides A generate crooked object and are adjusted such as Fig. 6.
Similarly, when the sides B generate it is crooked when, as shown in fig. 7, object is in transmit process, first occlusion detection sensor b1,
B2, i.e. detection sensor b1, b2 act output signal, conveyer belt B can be made to stop fortune by detection device output signal at this time
Row, conveyer belt A continue to run until that detection sensor a1, a2 is blocked, as shown in figure 4, i.e. detection sensor a1, a2 acts
Output signal makes conveyer belt B run at this time by detection device output signal, and conveyer belt A continues to run so that the sides B generate
Crooked object is adjusted such as Fig. 6.
Certain large-sized objects, such as the automobile in storage depot are conveyed in conveyer belt, since its front wheel side compares rear wheel-side
Weight, between conveyer belt and conveyer belt handing-over or transmission process in tremble, all can be object(Such as:Automobile)Side is always toward one
A direction is crooked, although constantly doing crooked adjustment, repeatedly, will produce cumulative offset, causes a longitudinal past direction to deviate, makes
The object that must be transmitted(Such as:Automobile)It causes to scratch even transmission tape jam beyond longitudinal allowable range to stop.As shown in Figure 8.
For this purpose, this invention proposes a solution:First, being respectively set two groups in the sides A of conveyer belt longitudinal direction and the sides B
Overlength detection sensor is object overlength early warning c2 and d2 and overlength alarm c1 and d1.When early warning detection sensor c2 or d2 are acted
When, do primary crooked adjustment if even if object does not generate crooked at this time, the only crooked adjustment of negative direction, i.e.,:It will be pre-
The alert conveyer belt for acting that side stops a period(It is specific how long, depending on line speed, size, transmission object
Quality and shape determine, several seconds usual;Or until crooked early warning detection sensor is failure to actuate), this biography of stopping
Send band to be further continued for running, be at this time it is artificial caused by it is crooked, when by next crooked test point, then do corresponding crooked tune
It is whole, it is transfinited with correcting longitudinal, as shown in Figure 9.When longitudinal overlength early warning c2 and d2 are acted, conveyer belt can run and carry out askew
Skew adjustment, when overlength alarms c1 and d1 action alarms, conveyer belt A and B must stop, and to prevent object scraping collision or fall down accident hair
It is raw.
Second is that be not provided with vertical misalignment detection sensor c1, d1, c2, d2, every time crooked adjustment it is secondary or three times after, with
It is above-mentioned similarly, in normal transmission is advanced, the crooked generation of a negative direction is done, until crooked tune is done in next crooked detection again
It is whole, with the cumulative offset of correcting longitudinal.As shown in Figure 10.
Detection sensor a1, a2, b1, b2 installation site for detection must be in a straight line, as much as possible with biography
Send band traffic direction vertical;A pair of of detection sensor of crooked detection that a1, a2 are conveyer belt A, b1, b2 are the askew of conveyer belt B
Tiltedly a pair of of detection sensor of detection;A1, a2, b1, b2 detection sensor are respectively placed in mounting bracket, the installation position of a1 and b1
The object higher than transmission is set, the installation site of a2 and b2 are generally in one at the intermediate position of two conveyer belts and with conveyer belt
Horizontal plane, in order to avoid being scratched by object, specific installation site regards conveyer belt and transmits the size decision of object, according to conveyer belt
With the size of transmission object, select the detecting distance of detection sensor, with occur object it is crooked when, the detection between detection sensor
Light or sound wave can reliably be blocked and do not influence conveyer belt operation and object above be transmitted as criterion, in this way to object
Crooked detection and adjustment can be only achieved optimum.The control device of crooked detection is electronic device, and appearance and size is small, visually
The space of conveyer belt and control panel disposes, and can also be included in conveyer belt control system.
During crooked detection and adjustment of the present invention, according to object skew condition, control device sends out control letter
Number, drive conveyer belt(Crawler belt)Crooked adjustment or the crooked adjustment of negative direction are done with actions such as the length travels that reduces object.
It is above-mentioned for conveyer belt unidirectional operation describe, if equipment allow conveyer belt it is two-way i.e. forward and reverse operation when, also can be by upper
It states method and carries out the crooked detection and adjustment of object.
