JPH0665330U - Stopping device for bogies traveling along guide rails - Google Patents

Abstract

(57) [Summary] [Purpose] To smoothly stop the traverser. [Structure] Traverser 5 is used as buffer rod 1 of shock absorber 17
Since the traverser 5 can be brought into contact with the elastic stopper 14 after the shock is absorbed by the shock absorbing action of the shock absorber 17, the stacked articles placed on the car 3 on the traverser 5 can be prevented. There is no risk of a load collapse.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stop device for a truck that travels along a guide rail.

[0002]

[Prior art]

 Conventionally, the following devices are known as this type of stopping device. That is, it is known that an elastic stopper is provided at the ends of a pair of guide rails whose longitudinal direction is directed to the left and right, and with which a truck traveling along the guide rails abuts.

[0003]

[Disadvantages of the prior art]

 The conventional stopping device for a truck traveling along the guide rail has the following drawbacks. That is, since the dolly was hit against the elastic stopper to improve the accuracy of the stop position of the dolly, the elastic coefficient of the elastic stopper must be large, that is, the elastic stopper must be slightly stiff. However, even if the bogie is decelerated considerably immediately before it comes into contact with the elastic stopper, the impact force applied to the bogie and the elastic stopper may be large, and in such a case, the impact is applied to the bogie. There is a drawback that the articles may collapse.

[0004]

[Means for eliminating the above drawbacks]

 This invention adopts the following means in order to solve the above-mentioned drawbacks. This invention has an elastic stopper and a shock absorber in which the carriage contact surface of the buffer rod projects from the carriage contact surface of the elastic stopper toward the carriage side.

[0005]

[Function of the device]

 This device has the following actions. First, the carriage is brought into contact with the cushion rod of the shock absorber to absorb the shock by the cushioning action of the shock absorber, and then the carriage is brought into contact with the elastic stopper.

[0006]

【Example】

 The present invention will be described below based on an embodiment shown in the drawings. In this specification, the front means the lower side of FIG. 1, the rear means the upper side of FIG. 1, the left means the left side of FIG. 1, and the right means the right side of FIG.

A first guide rail 1 composed of two rails, the longitudinal direction of which is directed in the front-rear direction, and a second guide rail 2 composed of two rails parallel to the first guide rail 1, A vehicle 3 which is guided and travels by a known traveling device (not shown), and which extends across the front end front of the first guide rail 1 and the front end front of the second guide rail 2 in the longitudinal direction in the left-right direction. A guide rail 4 for the traverser, which is a book rail, and a traverser 5 guided by the guide rail 4 to travel by a known traveling device (not shown) are provided.

A guide rail 10 including two rails on which the vehicle 3 is mounted is provided above the traverser 5.

A bracket 12 is attached to each of the left and right ends of the guide rail 4, and an elastic stopper 14 is attached to each of the brackets 12 via a liner 13 for position adjustment. A main body of a shock absorber 17 using a spring or hydraulic pressure is attached to the bracket 12, and a shock absorbing rod 18 of the shock absorber 17 has a coaxial through hole 20 formed in the bracket 12, the liner 13 and the elastic stopper 14. The traverser 5 side, that is, the traverser contact surface 18a of the buffer rod 18 projects toward the traverser 5 side from the traverser contact surface 14a of the elastic stopper 14. Further, the buffer rod 18 can be completely retracted into the through hole 20. Considering the speed of the traverser 5 when it hits the buffer rod 18, the force for projecting the buffer rod 18 causes the traverser 5 to move fully when the buffer rod 18 is pushed back by the traverser 5. The speed is adjusted to almost zero. The guide rail 10 is connected to the first guide rail 1 or the second guide rail 2 when the traverser 5 contacts the traverser contact surface 14a of the elastic stopper 14.

[0010]

[Operation of the embodiment]

 Next, the operation of the embodiment will be described. The case where the vehicle 3 is transferred from the second guide rail 2 to the guide rail 10 of the traverser 5 will be described as an example. The traverser 5 stopped on the left side is run toward the right side, and the traverser 5 is decelerated before the traverser 5 reaches near the right end. After that, the traverser 5 moves the cushion rod 18 back and moves further to the right, and in the state where the cushion rod 18 is completely retracted, it comes into contact with the elastic stopper 14 and stops completely. In that state, the guide rail 10 on the upper part of the traverser 5 is connected to the second guide rail 2, so that stacked articles (not shown) that have advanced along the second guide rail 2 are placed. The car 3 moves onto the guide rail 10 and then stops. After that, the traverser 5 is run to the left. After that, the traverser 5 is stopped on the left side of the guide rail 4 by an operation reverse to the above, and then the car 3 is moved toward the first guide rail 1 to transfer the car 3 to the first guide rail 1. You can do it.

[0011]

[Effect of device]

 The present invention has the following effects due to the above-described configuration. After the dolly is brought into contact with the buffer rod of the shock absorber to absorb the shock by the shock absorbing action of the shock absorber, the dolly can be brought into contact with the elastic stopper, so that the stacked articles placed on the dolly are collapsed. Can be prevented.
