A pusher-equipped trolley 20 and an auxiliary trolley 21 are movably supported on a guide rail 19.
It is suspended in the.

As shown in FIGS. 3 and 4, the trolley 20 with a pusher has a pusher 25 that can freely swing up and down via a support shaft 24 between a pair of left and right side walls 23a and 23b that are integrated with each other at the bottom 22. A pair of front and rear protruding shafts 26a, 2 are supported on the side walls 23a, 23b and project horizontally outward from the respective side walls 23a, 23b.
6b rotatably supports rollers 27a, 27b that fit into the guide rail 19, and furthermore, vertical shafts 29a, 29b are mounted on protrusions 28a, 28b protruding from both front and rear ends of the bottom portion 22 in the front-rear direction. A drive chain 3 is connected thereto. The drive chain 3 is connected to a center link 31 by a vertical pin 30.
and a pair of upper and lower side links 32 are alternately connected, and in the illustrated structure, the trolley 20 is also used as one of the upper side links, and the vertical shafts 29a, 29b are connected to two vertical pins, front and rear. It is also used for. The pusher 25 is urged upward by a weight portion 33 that protrudes from the free end on the opposite side to the support shaft 24 on both left and right sides.
The free end portion comes into contact with a stopper rubber 34 embedded in the end surface of 8a. 35 is a backing surface formed on the pusher 25 and is located in front of the support shaft 24. Reference numeral 36 denotes a drive release cam projecting from the pusher 25 on both the left and right sides, and is located diagonally rearward and above the support shaft 24. 37 is an anti-back projection for the main driven dog 16.

Further, among the vertical shafts 29a and 29b that project upward from the pair of front and rear projections 28a and 28b, the upper end of the vertical shaft 29b located directly below the pusher 25 is covered with a rubber cap 38. When the trolley 20 passes under the main driven dog 16 and the auxiliary driven dogs 17, 18, the rubber cap 38 causes the pusher 25 to move downward due to the collision between these driven dogs 16 to 18 and the anti-back protrusion 37. It will be pushed down, but at this time the pusher 2
5 by the rubber cap 38, it is possible to prevent the pusher 25 from colliding forcefully with the metal part of the trolley 20 and generating noise.

In the propulsion line 1 configured as described above, the pusher 25 of the trolley 20 is moved forward by the drive chain 3 as shown in FIG.
The main driven dog 16 of the conveyance movable body 7 is automatically fitted between the anti-back protrusion 37 and the conveyance movable body 7 is propelled by the pusher 25 that engages with the main driven dog 16. It will be done. In addition, in the section where the interval between the upper and lower guide rails 8 and 19 is reduced, the pusher surface 35 of the pusher 25 comes into contact with the sub-driven dog 17 or 18 of the conveyance movable body 7, so that the conveyance movable body 7 can be propelled in a boosted state.

In addition, as shown by the imaginary lines in FIGS. 3 and 4,
Cam 36 for driving release in the pusher 25
A stopper 3 that can be moved in and out freely protrudes into the movement path of the
9, the pusher 25 is tilted and swung against gravity, and the pusher 25 and the main driven dog 16 are
By disengaging the pusher 25 from the pusher 25, it is possible to release the pusher 25 from moving the transporting body 7. On the other hand, the pusher 25 can pass through the position of the stopper 39 in the lying position.
At this time, a protrusion 41 is protruded from the stopper 39 to abut a protrusion 40 protruding laterally from the main driven dog 16 and stop the deactivated conveyance movable body 7 at a certain position.

The propulsion line 4 using vertical drive chains 5a and 5b is as shown in FIGS. 5 and 6.
A trolley 20 on which the pusher 25 is pivotally supported is installed between a pair of left and right vertical drive chains 5a and 5b. That is, the rollers 27a, 27b of the trolley 20 are removed, and the horizontal protruding shafts 26a, 26b for supporting the rollers are used to move the left and right side walls 2.
Attachments 42a and 42b for attaching the drive chain are attached to the outside of the drive chains 3a and 23b, and the drive chain 5 is attached to both attachments 42a and 42b.
a and 5b are attached via horizontal connecting pins 43a and 43b. The drive chains 5a, 5b are a pair of left and right inner side links 44 and a pair of left and right outer side links 45 connected by a horizontal connecting pin with a roller, and the attachments 42a, 42b are connected to the outer side links. 45
The horizontal connecting pins 43a, 43
b also serves as a horizontal connecting pin with a roller that connects both the links 44 and 45. 46a, 46b
is a chain guide rail that movably supports the drive chains 5a and 5b, and is a fixed frame 47.
a, 47b. Note that when attaching the attachments 38a, 38b to the horizontal protruding shafts 26a, 26b for roller support, the protruding shafts 26
If a and 26b are too long, they can be cut to an appropriate length.

Incidentally, since the rubber cap 38 cannot be mounted using the vertical shaft 29b as shown in FIG. 3, the rubber cap mounting bolt 48 is mounted using the vertical shaft mounting hole of the protrusion 28b.
The rubber cap 38 is fitted onto the upper end of this bolt 48.

Also in the propulsion line 4 configured as described above, for example, the conveyor is pushed into the propulsion line 4 from the propulsion line 1 by the action of pushing the auxiliary driven dog 17 or 18 with the pushing surface 35 of the pusher 25. The moving body 7 is connected to a pair of left and right drive chains 5.
The engagement of the main driven dog 16 with the pusher 25 of the trolley 20 driven by the trolleys 20a and 5b allows the trolley to be propelled in the same way as the propulsion action in the propulsion line 1.

In addition, the pusher 25 provided on the trolley 20 and each driven dog 16 to 1 on the conveyance moving body 7 side
8, and by using the stopper 39, the drive chain 3 or the pair of left and right drive chains 5
It is no different from the conventional technology that it is possible to automatically store the moving body 7 in the propulsion line 1 or 4 without stopping the a and 5b. or,
It is also possible to feed the conveying moving body 7 from the end of the propulsion line 4 to the propulsion line 1, for example, by pushing the pusher 2.
This can be done by using the backing surface 35 of No. 5.

The trolley conveyor propulsion device of the present invention can be implemented like the propulsion line 4, and is a trolley with a pusher used in the propulsion line 1 using the horizontal drive chain 3, that is,
It is equipped with two protruding parts on the lower front and rear to which a horizontal drive chain is attached by a vertical shaft, a pair of horizontal protruding shafts for supporting rollers on the left and right sides, and a driven dog for the conveyance moving body on the upper part. A trolley provided with an engaging pusher is installed between a pair of left and right vertical drive chains via a pair of attachments attached to both left and right sides via the horizontally protruding shaft for supporting the roller. By simply using a pair of attachments, it is possible to construct a propulsion device using a vertical drive chain by reusing almost the pusher-equipped trolley used for the horizontal drive chain. Therefore, there is no need to change the configuration of the transportation moving body or the configuration of the stopper for storage or the like from the propulsion device using a horizontal drive chain, and the overall cost can be reduced significantly. In addition, as explained in the embodiment, the propulsion line 1 propels the transportation vehicle by a propulsion device using a horizontal drive chain.
It is also easy to design a layout that is suitable for the situation by arbitrarily combining the propulsion line 4 for propelling the conveyance moving body by a propulsion device using a vertical drive chain.

Note that the configurations of the pusher and the driven dog on the side of the conveyance moving body are not limited to the configurations shown in the embodiments.
For example, the pusher may be fixed to the trolley, and the driven dog side may be configured to be freely engageable and detachable from the pusher.
