Description

Collision prevention device

Technical field

This utility model relates to technical field of automation, a kind of anticollision for multistage tape transport product Device.

Background technology

In the last few years, machinery industry development from semi-automation to automatization, it is achieved that the change at full speed of machinery industry, respectively Plant automation equipment to be constantly manufactured；The most whether, in still producing in life, facilitating of plastic is light so that People are increasing to the demand of plastics, thus the production of plastics is also required to accelerate.Plastics are that injection is formed on injection machine, On intelligent moulding production line, injection machine uses robot pickup, commonly uses conveyer belt in present intelligent production line Transport, conventional conveying is with many levels, during particularly injection machine intellectuality produces, two-stage conveyer belt be divided into machine limit conveyer belt and Main conveyor belt, is transported to fixed position by machine limit conveyer belt and main belt by product, then passes through at main belt end The operations such as vision sorting machine people sort, vanning；And between two conveyer belts, have individual confluence, produce at confluence two conveyer belt If product arrive simultaneously, will collide between product and product, produce scratch, overlap etc., affect the sorting of sorting machine people Quality, thus affect the quality of production and the production efficiency of product.

Summary of the invention

Problem to be solved in the utility model is to provide and a kind of is avoided that product during production and transport collides Collision prevention device.

In order to solve the problems referred to above, the technical solution adopted in the utility model is: this collision prevention device, includes at machine First sensor that limit conveyer belt and main conveyor belt intersection edge are each arranged and the second sensor, described first sensor Being in series with the coil of the first relay on the loop of normally opened contact, the normally-closed contact of this first relay is connected on the time relay Coil loop on；The time delay normally-closed contact of the described time relay is connected on the loop of the second relay coil；Described The coil of the 3rd relay it is in series with on the loop of the normally opened contact of the second sensor；The normally-closed contact of described second relay with Formation machine limit conveying of connecting with the control circuit of machine limit conveyer belt motor after the normally-closed contact parallel connection of described 3rd relay is charged Machine control circuit.In technique scheme, more specifically scheme is it may also is that described first sensor and described second senses Device is laser sensor.

Owing to have employed technique scheme, this utility model compared with prior art, has the beneficial effect that this reality With novel by sensor with the cooperation of relay, it is to avoid sending out of the defective products that the collision of product causes during production and transport Raw, thus improve production efficiency.

Accompanying drawing explanation

Fig. 1 is conspectus of the present utility model.Fig. 2 is conveyer belt schematic diagram of the present utility model.

Detailed description of the invention

The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:

Collision prevention device shown in Fig. 1 and Fig. 2, includes and each sets at machine limit conveyer belt and main conveyor belt intersection edge The first sensor ETL1 put and the second sensor ETL2, the loop of the normally opened contact of first sensor ETL1 is in series with first The coil of relay K A1, on the loop of the coil that the normally-closed contact of this first relay K A1 is connected on time relay KT；Time Between the time delay normally-closed contact of relay K T be connected on the loop of the second relay K A2 coil；Second sensor ETL2's is normally opened The coil of the 3rd relay K A3 it is in series with on the loop of contact；The normally-closed contact of the second relay K A2 and the 3rd relay K A3 Normally-closed contact parallel connection after connect with the control circuit of machine limit conveyer belt motor formation machine limit conveyer belt circuit for controlling motor.This reality Executing in example, first sensor ETL1 and the second sensor ETL2 is laser sensor.Hand over machine limit conveyer belt at main conveyor belt At remittance, edge sets laser sensor, then measures confluence length and the speed of main conveyor belt, according to this length and speed Calculate the time t transferring out confluence after product departs from laser sensor, time t is arranged on time relay KT.As Really the laser sensor of confluence has sensed product simultaneously, the normally opened contact of first sensor ETL1 and the second sensor ETL2 Normally opened contact Guan Bi, the coil of the first relay K A1 and the coil of the 3rd relay K A3 obtain electric adhesive, the first relay K A1 Normally-closed contact disconnect, the coil of time relay KT not electric cannot adhesive, the time delay normally-closed contact of time relay KT It is in closure state, makes the second relay K A2 coil obtain electric adhesive, due to the second relay K A2 coil and the 3rd relay K A3 Coil be in attracting state, so the normally-closed contact of the normally-closed contact of the second relay K A2 and the 3rd relay K A3 is in Off-state so that machine limit conveyer belt circuit for controlling motor dead electricity, machine limit conveyer belt motor shuts down, and machine limit conveyer belt stops Conveying；After elapsed time t product safety transfers out confluence, laser sensor has not sensed product, first sensor The normally opened contact of ETL1 disconnects, and the releasing winding of the first relay K A1, the normally-closed contact of the first relay K A1 is in closed form State, the coil of time relay KT obtains electric adhesive, and the time delay normally-closed contact of time relay KT disconnects, the second relay K A2 line Circle release, is in release conditions, so the normally-closed contact of the second relay K A2 is in closed form due to the second relay K A2 State so that machine limit conveyer belt circuit for controlling motor obtains electric, machine limit conveyer belt motor rotation, machine limit conveyer belt normally carries；As long as In the middle of two laser sensors one has not sensed product, and two conveyer belts can be properly functioning.
