Description

DETAILED DESCRIPTION OF THE INVENTION The present invention utilizes a conventional pusher-equipped trolley that is attached to a horizontally rotating driving chino and is movably supported by a pair of left and right guide rails via a horizontal axis roller. The present invention is designed so that a trolley conveyor propulsion device using a vertical driving chain can be constructed at low cost.

Hereinafter, one embodiment of the present invention will be described based on the attached illustrative drawings. In the layout shown in FIG. 4 is a propulsion line using a suspended horizontal driving chain 6; 4 is a propulsion line using a pair of left and right vertical driving chains 5a, 5b; There is.

The first trolley 9 to the fourth trolley 12 are movably supported by the first trolley 9 to the fourth trolley 12, the connecting rod 1i5 connecting the first trolley 9 and the second nitrolley 10, and the third trolley 11 and the fourth trolley 1.
2, and a connecting rod 14 that connects the
and a third trolley 11, and connects both trolleys 10 and 11. Further, the first trolley 9 has a main driven dog 16.
The third trolley 11 and the fourth trolley 12 have auxiliary driven dogs 17 and 18 projecting from the third trolley 11 and the fourth trolley 12, respectively. Further, the horizontally arranged driving gears 6 are suspended from a pusher-equipped trolley 20 and an auxiliary trolley 21 movably supported by a guide rail 19.

As shown in FIGS. 3 and 4, the pusher-equipped trolley 20 has a pusher 25 that can be vertically swung via a support shaft 24 between a pair of left and right side walls 2i5a and 25b that are integrated with each other at the bottom 22. supported on both side walls 2i5a.
, rollers 27a, 27b that fit into the guide rail 19 are rotatably supported on a pair of front and rear protruding shafts 26a, 26b that protrude horizontally outward from each of the bottom portions 22. A drive engine is connected via vertical shafts 29a, 29b to protrusions 28a and 28b that protrude from both ends in the front-rear direction. In the structure shown in C1, the trolley 20 marked with 0 is also used as one of the upper side links, and the vertical shafts 29a and 29b are connected to the two front and rear vertical pins. The pusher 25 is urged upward by a weight portion 3 that projects from the free end on the opposite side to the support shaft 24 on both the left and right sides.
The free end portion comes into contact with a stopper rubber 34 embedded in the end surface of. Reference numeral 65 denotes a backing surface formed on the grip shear 25, and is located in front of the support shaft 24. 36 is pusher 25
This is a drive release cam that protrudes to both left and right sides from the support shaft 24, and is located diagonally rearward and above the support shaft 24. 67 is main driven dog 1
This is an anti-bank protrusion for 6.

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 button shear 25 is covered with a comb cap 68. This rubber camp 38 connects the lower side of the main driven dog 16, auxiliary driven dogs 17, 18, etc. to the trolley 2.
0 passes, the pusher 25 is pushed down by the collision between these driven dogs 16 to 18 and the anti-back protrusion 57, but at this time, by stopping the pusher 25 from being received by the rubber cap 38, It is possible to prevent the pusher 25 from violently colliding with the metal part of the trolley 20 and generating noise.

In the propulsion line 1 configured as described above, as shown in FIG. The main driven dog 16 is automatically engaged, and the moving body 7 for one movement is propelled by the pusher 25 that engages with the main driven dog 16.

In addition, in the section where the distance between the upper and lower kite rails 8 and 19 is reduced, the pushing surface of the pusher 25 comes into contact with the auxiliary driven dog 17 or 18 of the moving body 7 for transporting the transport. The body 7 can be propelled in a boosted state.

As shown by the imaginary lines in FIGS. 3 and 4, the pusher 25 is moved against gravity by a stopper 69 that protrudes into the moving path of the drive release cam 36 in the pusher 25 and is retractable. The pusher 25
By releasing the engagement between the main driven dog 16 and the main driven dog 16, it is possible to release the propelling action of the transport moving body 7 by the pusher 25. 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 and abuts on a protrusion 40 protruding laterally from the main driven dog 16 to stop the deactivated conveyance movable body 7 at a certain position.

As shown in FIGS. 5 and 6, the propulsion line 4 using vertical drive chains 5a and 5b connects the trolley 20, which pivotally supports the pusher 25, to a pair of left and right vertical drive chains 5a+5. It is installed between b. That is, remove the rollers 27a and 27b of the trolley 20,
Using these horizontal protruding shafts 26a, 26b for roller support, axotimments 42a, 42b are attached to the outside of the left and right side walls 2:5a, 2i5b. 5
a and 5b are attached via horizontal connecting pins 43a and 4i5b. The drive chinos 5a, 5b are configured by connecting a pair of left and right inner side links 44 and a pair of left and right outer side links 45 by a horizontal connecting bin with a roller, and the attachments 42a, 42b are connected to the outer side links 45. The horizontal connecting pins 43a and 43b also serve as horizontal connecting pins with rollers that connect both the links 44 and 45. 46a, 46
b is a cheno guide rail that movably supports the drive chinos 5a, 5b, and includes fixed frames 47a, 47b.
laid on top. In addition, attachments 38a, 38
b to the horizontal protruding shafts 26a, 26b for roller support, the protruding shafts 26a.

If 26b is too long, it can be cut to an appropriate length.

Note that the rubber camp 68 cannot be mounted using the vertical shaft 29b as shown in FIG. The rubber camp 68 is fitted to the upper end of this pole 1-48.

In the propulsion line 4 configured as described above, ζ is also 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 pusher surface 65 of the pusher 25, for example. The feeding moving body 7 is propelled in the same manner as the propulsion action in the propulsion line 1 by engagement between the pusher 25 of the trolley 20 and the main driven dog 16 driven by the pair of left and right drive chains 5a and 5b. I can do it.

Note that the pusher 25 and I provided on the trolley 20
By using each of the driven dogs 16 to 18 on the side of the I-transfer moving body 7 and the stopper 69, the propulsion line 1 or the propulsion line 4 can be moved without stopping the drive engine 6 or the pair of left and right drive chains 5a, 5b. The ability to automatically strain the conveyance moving body 7 in this case is the same as in the past. Further, the conveying moving body 7 can be sent into the propulsion line 1 from the end of the propulsion line 4 by using, for example, the rearing surface 35 of the pusher 25.

The present invention (r)) The trolley conveyor propulsion device can be implemented like the propulsion line 4 described above, and includes a trolley with a pusher used in the propulsion line 1 using a horizontal drive chain 6, i.e. 〢It has two protruding parts on the lower front and back to which the horizontal drive chino can be attached using a vertical shaft, a pair of horizontal protruding shafts for supporting rollers on the left and right sides, and a driven dog of the transport moving body on the upper part. A trolley provided with an engaging button shear 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 horizontal protruding shaft for supporting the roller. By simply using a pair of Axotimens I, a trolley with a pusher used for a horizontal drive engine can be used almost as is, and a propulsion device using a vertical drive chain can be constructed. 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 chino, and the overall cost can be reduced significantly. In addition, as explained in the embodiment, there is a propulsion line 1 that propels the transportation vehicle by a propulsion device using a horizontal drive chain, and a propulsion device that uses a vertical drive chain to propel the transportation vehicle. It is also easy to design a layout adapted to the situation by arbitrarily combining the stirring propulsion lines 4.

Incidentally, the structure of the driven dog in the pusher and on the conveyance moving body side is not limited to the structure shown in the embodiment.

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.
