DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. In this embodiment, as an example of transport equipment using a moving body, as shown in FIGS. 1 and 5, a suspended transport device 1 that transports an object to be transported on a fixed path on the ceiling side is shown. The hanging and conveying device 1 is an example of a trolley guide rail 2 which is an example of a rail device, a driving body rail 3 provided above the trolley guide rail 2, and a moving body supported and guided by the trolley guide rail 2. The trolley device 4 includes a trolley device 4, a transport device supporting device 5 attached to the trolley device 4, and a driving body (such as a chain conveyor) 6 supported and guided by the driving body rail 3.

The trolley device 4 includes a front trolley 7
A connecting rod 10 for connecting between the trolley 8, the rear trolley 9, the front trolley 7 and the free trolley 8, and a connecting for connecting between the trunnion pins 11 provided continuously from the free trolley 8 and the rear trolley 9. It is composed of a frame 12 and the like. The supporting device 5 includes a C-neck 13 attached to the lower ends of the two trunnion pins 11, an arm 14 extending downwardly attached to the lower portion of the C-neck 13, and a horizontally provided horizontal portion at the lower end of the arm 14. And the like. Each of the trolleys 7, 8, and 9 includes a guide wheel 16 supported and guided by the trolley guide rail 2 and a side-runout prevention wheel.
17 respectively.

As shown in FIGS. 1 to 4, the front trolley 7 has a passive body 20 which can be freely engaged and disengaged with a transmission (pusher dog) 18 from the driving body 6 and can move up and down. An operating lever 22 is attached to the left and right sides so as to be a fulcrum. The rear end of the operation lever 22 and the lower end of the passive body 20 are connected via a pin 23 in the left-right direction so as to be relatively swingable.

Therefore, the operating lever 22 and the passive body 20 are
When the front end side of the operation lever 22 moves upward, the passive body 20 is linked so as to descend. At this time, the lifting and lowering of the passive body 20 is performed by the cylindrical body 24 attached to the guide wheel shaft and the front trolley 7.
Is guided by the guide body 25 formed at the center. Normally, the operating lever 22 is urged by the weight portion 22A so that the front end thereof moves downward so that the upper end of the passive body 20 protrudes into the movement path of the transmission 18.

The front trolley 7 is provided with a downwardly abutted portion 26, and an upwardly abutting portion provided on the rear end side of the operating lever 22 contacts the abutted portion 26 from below. In addition, the lower limit of the operation lever 22 due to its own weight is regulated. Here, the contacted part 26 is integrated with the front trolley 7,
For example, it is made of metal such as iron.

The contact portion is formed by a cylindrical rubber body 27 made of, for example, fluoro rubber. The mounting to the operation lever 22 is performed by press-fitting into a concave portion 28 formed on the upper surface side of the rear end of the operation lever 22. Here recess 28
Is formed such that the inner diameter 28b at the back is larger than the inner diameter 28a at the opening, that is, 28a <28b.
Is formed substantially equal to the inner diameter 28b of the back, that is, 27a ≒ 28b.

At the upper end of the front trolley 7, the passive body
At a position rearward of 20, a runaway preventing body (hold dog) 30 for preventing the passive body 20 from running away forward when the transmission body 18 and the passive body 20 are engaged is provided. This runaway inhibitor
Numeral 30 is configured to be able to swing back and forth via a pin 31, and normally, its upper end is urged by a weight portion 30 </ b> A so as to protrude into the movement path of the transmission 18.

In order to maintain the engagement between the power transmitting member 18 and the passive member 20, the runaway preventing member 30 is a regulated portion which can freely contact from behind a regulating portion formed on the rear surface of the front trolley 7. (Regulated surface) 32 is provided at the lower part. Here, the restricting portion is the same as the above-described operation lever 22 side, and is formed of a cylindrical rubber body 33 made of, for example, fluoro rubber. The mounting on the front trolley 7 is performed by press-fitting into a concave portion 34 formed on the rear surface side of the front trolley 7.

As shown in FIG. 5, the other rear trolley 9
The cam tail 35 for moving the operation lever 22 upward is extended rearward. Reference numeral 37 denotes a transferred object. Next, the operation of the above embodiment will be described.

Usually, the trolley device 4 is moved on a fixed path by receiving the moving force of the driving body 6 by engaging the transmission 18 with the passive body 20 as shown in FIG. At this time, as shown by a solid line in FIG. 1, the operating lever 22 is urged by the weight portion 22A so that the front end thereof moves downward, thereby raising the passive body 20 and moving the upper end thereof to the transmission body 18. Into the moving route of Further, the contacted part 26
The rubber body 27 abuts from below to restrict the lower limit of the operation lever 22 due to its own weight. When the trolley device 4 tries to run away during the above-described movement, the runaway preventing body 30 comes into contact with the rear surface of the transmission 18 so that the runaway is prevented.

When the trolley device 4 is stopped at a predetermined stop position, when the trolley device 4 to be stopped approaches, the stopper body is moved to a passive body by a cylinder device or the like.
We rush into 20 movement routes from the side. Then, as shown by the phantom line in FIG. 1, first, the passive body 20 is pushed down by the stopper body and disengaged from the transmission body 18, the trolley device 4 is in a non-drive state, and the runaway preventing body 30 is attached to the stopper body. Collides, and further movement is stopped.

The trolley device 4 stopped as described above
When the subsequent trolley device 4 approaches, the operation lever 22 of the subsequent trolley device 4 rides on the cam tail 35 provided on the rear trolley 9 of the preceding trolley device 4. As a result, the operation lever 22 swings around the horizontal axis 21 so that the rear end is lower against the weight bias, as shown by the imaginary line in FIG. It will be lowered and separated from the transmission 18. At this time, the rubber body 27 is separated from the contacted portion 26 downward.

To move the trolley device 4 stopped as described above again, first, the stopper body is retracted. Then, the pressing force of the stopper body to the passive body 20 is released, so that the urging of the weight portion 22A causes the operating lever 22 to move down at the front end side and to move up the passive body 20. As shown by the solid line in FIG. At this time, the upper limit is
Is restricted by contacting the contacted portion 26, and at that time, the collision (contact) is performed softly because it is a collision with the rubber body 27, and a loud noise (collision sound) is generated.
The operating lever 22 is not damaged.

In this state, the operation of the driver 6 causes the transmission 18
Comes from behind. And the transmission 18 is a runaway prevention body
As shown by the imaginary line in FIG. 1, the upper part 30 collides with the upper part of the runaway stopper 30 and swings forward around the pin 31 so that the regulated part 32 is separated from the rubber body 33. . The transmission 18 that has passed through the portion of the runaway prevention body 30 in this manner engages with the passive body 20, so that the trolley device 4 can be moved by the moving force of the driving body 6. Further, as the transmission body 18 passes, the runaway preventing body 30 swings backward (restoring swing) around the pin 31 by the bias of the weight portion 30A, and this swing is regulated with respect to the rubber body 33. It is performed until the unit 32 collides (contacts). Since the collision at this time is a collision with the rubber body 33, the collision is performed softly, and no loud noise (collision sound) is generated and the runaway preventing body 30 is not damaged.

As shown in the above embodiment, when the contact portion is formed by the rubber body 27, the operation of forming the rubber body 27 and the work of exchanging for wear can be easily performed on the operation lever 22. In the first invention, the contacted part may be formed of a rubber body, and further, both the contacted part and the contacted part may be formed of a rubber body.

As shown in the above embodiment, when the rubber body 27 is made of fluoro rubber, heat resistance, chemical resistance,
Since it is excellent in water resistance and organic solvent resistance, it can be used for various transport equipment, but in the first invention, a rubber body other than fluororubber may be used.

As shown in the above embodiment, the opening inner diameter 28
A cylindrical rubber body 27 is provided in a concave portion 28 having an inner diameter 28b deeper than a.
When the rubber member 27 is press-fitted, the forming operation of the rubber member 27 and the replacing operation for the abrasion can be easily performed by using the rubber elastic force, and the mounting posture can be maintained by the rubber elastic force. May have a configuration other than a cylindrical shape such as a rod shape, and attachment is optional.

In the above embodiment, the hanging and conveying device 1 using the trolley device 4 as the moving body is shown, but it may be a floor conveyor device using a cart as the moving body.

[0031]

According to the first aspect of the present invention, while the front trolley and the operation lever can be constructed inexpensively, for example, made of iron, the collision of the abutting portion with the abutted portion is not caused by the rubber body . Therefore, the operation can be performed softly, noise at the time of restricting the operation of the operation lever can be reduced, and damage to the front trolley and the operation lever can be reduced. In addition, replacement work for rubber body forming work and abrasion
In some industries, rubber elastic force is applied to the operation lever.
It can be easily performed and the mounting posture is rubber bullet
It can be firmly maintained by sexuality.

According to the configuration of the second aspect of the present invention ,
