Description

DETAILED DESCRIPTION OF THE INVENTION The present invention enables conveyance objects having a large length and width, such as automobiles, to be conveyed freely up and down, left and right in a stable state, and also allows the conveyance object supporting member to be moved upwardly by being pushed by a traveling chain. This invention relates to a butcher conveyor device that can make the slit width provided in the floor extremely narrow and prevent foreign matter, paint, etc. from entering under the slit when a carrier connected to the slit is placed under the floor.

The conventional butsha conveyor device was developed in U.S. Patent Publication No. 57-00771.
As shown in No. 7, the front and rear carriers, which are connected by a conveyance support member and pushed by a lower running chain, are guided by rollers, two on each side, on the left and right carrier rails. Since it is configured to run, horizontal
There is a lot of rattling from side to side of the carrier when moving. In addition, horizontal and vertical hinges must be provided at the connection between the conveyed object support member and the carrier so that the carrier can move horizontally and vertically. The structure is complicated, and the conveyed object supporting member is likely to wobble.

The present invention solves the above-mentioned drawbacks, and allows objects of large length and width, such as automobiles, to be conveyed freely up and down, left and right in a stable state without rattling, and is further supported by being pushed by a traveling chain. To provide a bumper conveyor device that can make the width of the slit in the floor extremely narrow to prevent foreign objects, paint, etc. from entering under the slit when a carrier connecting members to the upper part is placed under the floor. Two carriers are provided at the front and rear, each having one roller running thereon on each side and a guide roller guided by the side of the carrier rail installed in the center, and the front and rear carriers are separated from each other to form a conveyed object support member. The carriers are horizontally rotatably connected to connecting shafts provided upright, and the carriers are pushed by traveling chains located below the front and rear carriers.

□ An embodiment of the present invention will be described below based on the drawings.

do.

In Figures 1 to 3, 1.1' indicates two carriers, front and rear, which are placed apart from each other under the floor, each having one roller 5 on each side that runs on two carrier rails 2 in parallel, and one in the center. It has two guide rows (4) at the front and rear that are guided by the side surface of the carrier rail 2 on the top surface of the carrier rail 2.5 is the front carrier 1.
The rear carrier 1' has a presser metal fitting for releasing the hook of the ridge carrier from the chain button (to be described later). The front and rear carriers 1.1' are horizontally rotatably connected to a connecting shaft 7 vertically disposed on the conveyed object support member 6. The connecting shaft 7 has a shape having a side recess 9 for inserting one end of a dustproof cover to prevent foreign matter and paint particles from entering under the slit 8 in the floor.
A dustproof cover 10 with its end inserted is erected on the floor. 11 is a running chain 12 disposed below the front and rear carriers 1.1' and attached to the chain 11 and engaged with the hook 5 of the carrier 12)'
F-:r--7 puttu, /:, Ya-Cah.

The present invention is constructed as described above. Therefore, the conveyed article 13 supported by the conveyed article support member 6 is conveyed on the carrier rail 2 as the hook 5 of the carrier 1 engages with the chain button 12 of the traveling chain 11 and is pulled. .

The present invention has two rollers running on carrier rails, one on each side of the carrier, and the front and rear carriers are separated from each other and connected horizontally rotatably to connection shafts installed upright on a conveyed object support member. Therefore, it is of course possible to freely make horizontal and vertical curves (see FIGS. 4 and 5).

Furthermore, since the carrier is guided by the guide roller installed in the center and the side surface of the carrier rail, it can run stably without wobbling from side to side when it is leveled. The structure is simple and the cost is low because the front and rear carriers are separated from each other and are horizontally rotatably connected to connecting shafts installed upright on the conveyed object support member, so the carriers are placed under the floor. In this case, the width of the slit provided in the floor can be made extremely narrow, which has various excellent effects such as preventing foreign matter, paint, etc. from entering under the slit.

Note that the connecting shafts 7 vertically disposed on the conveyance object supporting member 6 are connected to the first to fifth
As shown in the figure, if the dust cover 10 has a shape with a side recess 9 for insertion into the end, the dust cover 10 can completely prevent foreign objects, paint, etc. from entering the conveyor through the slit 8. can. Further, by making the top surface of the cover 10 slightly inclined, foreign matter and paint particles falling on the top surface of the cover 10 flow down to the floor surface without being fixed on the top surface of the cover 10. Furthermore, by slightly raising the floor surface at the slit 8@, it is possible to reliably prevent foreign objects, paint, etc. that have fallen onto the floor from the end of the cover 10 from entering the slit 8.

In addition to the dustproof cover shown in FIG. 3, the dustproof cover 10 is provided oppositely on both sides of the connecting shaft 7 of the concave portion 9 as shown in FIG. 6, or the dustproof cover 10 is provided oppositely as shown in FIG. By using a material that completely hides the gap through which the connecting shaft 7 of the dust-proof cover 10 passes with an elastic material 10a made of rubber to the extent that the connecting shaft 7 can pass through, it is possible to reliably remove foreign objects and paint. etc. can be prevented from entering the slit 8.

In Figures 8 to 10, carriers 15 are further inserted through distance pars 14 at the front and rear of the outer sides of the two front and rear carriers 1 and 1'.
．． 15' are connected, and a relatively long conveyed object 16 is shown.
can be transported. The outer carrier 15.15' is of the same construction as the inner carrier 1.1', except that it has two rollers 3 on each side on each side; A lever rod 17 is rotatably pivoted, and a running chain 11 is attached to the lower end of the lever 41-17.
The second carrier 15' is provided with a hook 5 that engages and disengages from the chain button 12, and a sensor rod 18 is provided at the upper end thereof, and the second carrier 15' comes into contact with the sensor rod 18 and pushes up the sensor rod 18, and the subsequent carrier A push-up rod 19 is attached to release the connection between the hook and the chain gripper.
