Description
Technical field
The utility model relates to a kind of automatic detection device, particularly relates to reflective without connecting line type pallet fork movable machinery conflict automatic detection device.
Background technology
Pallet fork motion refers to the mechanical action that pallet fork is protruding from article carrying machine or retract, article carrying machine includes but not limited to piler, fork truck, mechanical arm, robot, this mechanical action can be rectilinear motion or circular motion, and the pallet fork of the article carrying machine mechanical action that stretches has been used for picking or deliver goods operation.If pallet fork at the volley with other article generation mechanical conflicts in surrounding environment, the consequence such as damage, the damage of pallet fork, the damage of article carrying machine of position in storehouse of the falling of article, stores may be caused.
At present, after there is mechanical conflicts in moving for preventing pallet fork, pallet fork continuation motion causes damage, existing detection guard method or device: (1) in the driving-chain of pallet fork, increase clutch coupling, resistance is increased to clutch mechanism action after certain numerical value when a collision occurs, pallet fork and power source are disconnected, avoiding conflict and cause badly damaged consequence, is a kind of passive-type safety guard; (2) drive the parameter of power source indirectly to judge whether mechanical conflicts occurs by detecting pallet fork, as judged whether to clash by the electric current of detection drive motor, this is that one indirectly detects protected mode, and detection accuracy is limited, easy flase drop and undetected; (3) displacement detecting sensor or force detection sensor are installed on pallet fork and whether mechanical conflicts occur to detect pallet fork motion.Due to the mechanical dimension of pallet fork, it is range limited that the sensor of installation detects, the method also easy flase drop and undetected.Meanwhile, the sensor of installation moves with pallet fork, needs the circuit of sensor to connect from pallet fork to guide to the relatively-stationary parts of article carrying machine, thus causes inconvenient in actual applications; (4) directly use noncontact acquisition sensor, as the detection such as ultrasound wave, photoelectric sensor mechanical conflicts, but sensor is not easily adjusted to suitable sensing range and sensitivity, easily the object in surrounding enviroment is mistaken for mechanical conflicts.
Utility model content
Technical problem to be solved in the utility model be to provide one accurately, reliably, easily reflective without connecting line type pallet fork movable machinery conflict automatic detection device.
For solving the problem, described in the utility model reflective without connecting line type pallet fork movable machinery conflict automatic detection device, it is characterized in that: multiple retroreflecting plates that this device comprises the comb block of, a retroreflecting formula photoelectric sensor and is arranged on pallet fork machined surface; Described comb block parallel lay-up is on described multiple retroreflecting plate and be slidably connected with the machined surface of described pallet fork, and which is provided with several perforate, this several perforate and described multiple retroreflecting plate match; Described retroreflecting formula photoelectric sensor is located at the front, side of described comb block, and is fixed on the side base of described pallet fork.
Described comb block is rectangular slab, which is provided with 1 ~ 1000 rectangular perforate; The length of described perforate is 0.1 millimeter ~ 1000 millimeters, and its width is 0.1 millimeter ~ 1000 millimeters.
The utility model compared with prior art has the following advantages:
1, the utility model directly detects mechanical conflicts with the contact of the article that conflict by the comb block be arranged on pallet fork, can overcome some existing detection method or device is easily mistaken for service load mechanical conflicts thus undetected deficiency under light load.
2, the utility model directly detects mechanical conflicts with the contact of the article that conflict by the comb block be arranged on pallet fork, can overcome some existing detection method or device and easily under heavy loading Payload is mistaken for conflict thus the deficiency of flase drop.
3, the utility model directly detects mechanical conflicts with the contact of the article that conflict by the comb block be arranged on pallet fork, can overcome and directly use the noncontact acquisition sensor easily deficiency causing erroneous judgement affected by environment.
4, the utility model only mounting broach block retroreflecting plate on pallet fork, drawing relatively-stationary parts on signal wire to machine without the need to connecing from the pallet fork of motion, simplifying installation, it is convenient to implement, and reliability is higher.
5, the utility model belongs to active safety detection protective device; adopt direct-detection mechanical conflicts mode; for article carrying machine carries out protection provide signal to the mechanical conflicts in motion, detect promptly and accurately and not easily undetected and flase drop, thus improve the security of article carrying machine.

Embodiment
As shown in Fig. 1 ~ 3, reflective without the conflict of connecting line type pallet fork movable machinery automatic detection device, comb block 1, retroreflecting formula photoelectric sensor 2 that this device comprises and the multiple retroreflecting plates 3 be arranged on pallet fork 6 one machined surfaces 5.Comb block 1 parallel lay-up is slidably connected on multiple retroreflecting plate 3 and with the machined surface 5 of pallet fork 6, which is provided with several perforate 4, and this several perforate 4 matches with multiple retroreflecting plate 3; Retroreflecting formula photoelectric sensor 2 is located at the front, side of comb block 1, and is fixed on the side base of pallet fork 6.
Wherein: comb block 1 is rectangular slab, which is provided with 1 ~ 1000 rectangular perforate 4; The length of perforate 4 is 0.1 millimeter ~ 1000 millimeters, and its width is 0.1 millimeter ~ 1000 millimeters.
The utility model can install many covers on a pallet fork 6 simultaneously.
Principle of work:
When not there is mechanical conflicts, the part of the non-perforate of comb block 14 just blocks each retroreflecting plate 3, as shown in Figure 3.Retroreflecting formula photoelectric sensor 2 is not owing to being irradiated on retroreflecting plate 3, and retroreflecting formula photoelectric sensor 2 sends mechanical collision signal.
When during pallet fork 6 is according to Fig. 3 there is mechanical conflicts in indicated direction motion, first comb block 1 touches the object on motion path, cause comb block 1 to sliding in the other direction, the part of comb block 1 perforate 4 overlaps with each retroreflecting plate 3, as shown in Figure 4.The hot spot 7 of retroreflecting formula photoelectric sensor 2 projection is irradiated on retroreflecting plate 3, and retroreflecting formula photoelectric sensor 2 has sent mechanical collision signal.
