Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a vehicle body conveying device, and more particularly, to a vehicle body conveying device used in a production line for automobiles and the like.

(Prior art) As a vehicle body conveyance device, a roller conveyor is used to convey the vehicle body directly, as described in Utility Model Publication No. 56-33941 ``Dolly'', etc., and Utility Model Publication No. 57-51209 ``Car body conveyance device'' etc. Means such as carrier means and the like are known.

In addition, 1984-4845 “Transport device using a trolley”
is also known. The device relates to a vehicle body transfer device that moves a movable trolley along a rail.

(Problem to be solved by the invention) However, since the purpose of bogies and carriers is to place the entire car body, their weight and volume are large. The problem is that the heat capacity from the furnace is large, requiring extra heating and increasing heat loss.The trolleys are bulky and take up space, and the line is also large-scale, making it difficult to maintain and repair painting equipment. The problem was that it was difficult to store trolleys, etc. Furthermore, the roller bearing method had the problem of complicating the mechanism.

In addition, 1984-4845 “Transport device using a trolley”
However, since the transport vehicle is equipped with trolleys on the front, rear, left, and right sides, the transport vehicle has a problem in that the storage space of the transport vehicle becomes large when it is not in use.

(Means for solving the problem) This invention consists of a conveyor installed along the work line, and a plurality of conveyors installed vertically on both sides of the conveyor, supporting the conveyed objects at the upper end and having contact parts at the lower end. A vertical book support, and a plurality of horizontal supports that are installed almost horizontally on the conveyor, straddling the conveyor, are locked to the conveyor in the center, are moved by the conveyor, and connect the vertical support pillars located on both sides of the conveyor. A stand consisting of a stand, a plurality of rails installed along the conveyor with the conveyor sandwiched between the abutting parts of the vertical supports connected by the horizontal supports, and rollers attached to the rails. To provide a vehicle body transport device, comprising a number of trolleys on which the number of trolleys is placed, the number of which corresponds to the number of abutting parts of the stand, each of which is placed with a contacting part of the stand, and which is moved along a rail. This solves the problems of conventional vehicle body transport devices.

(Function) The object to be transported is placed on the vertical support of the stand, and placed on the trolley installed on the rail at each contact portion of the stand. Then, the contact portion of the stand is pressed against the trolley due to the load of the transported object. As the conveyor moves, the horizontal support of the stand that is locked to the conveyor is moved, and as the abutting part moves, the trolley is activated by rollers to place the object to be transported, and the object to be transported and the trolley move along the rail. move without compromising close contact with the object.

When the stand is not in use, the conveyor and the stand side support are simply locked together, so the stand can be removed from the conveyor. The stand and trolley can be separated because they are only in close contact with each other due to the pressing force.
In addition, even if the trolley is supported by multiple stands such as the front and rear stands, the front and rear stands are separate from each other, so these should be stored separately when not in use. .

(Example) An explanation will be given with reference to FIG. 1 showing a front view of an example of this invention, FIG. 2 showing details of section A in FIG. 1, and FIG. 3 showing a partially enlarged view.

1 is a stand. 8 is a con hair;
This embodiment consists of a chain conveyor, which is installed along a paint drying line on a work surface in a factory. Reference numeral 10 denotes an object to be transported, which in this embodiment is composed of an automobile body. The stand 1 consists of a contact portion 2, a vertical support 3, and a horizontal support 4. A total of four vertical supports 3 are vertically installed on both sides of the conveyor 8, two on each side, and support the transported object 10 by bringing its upper end into contact with the transported object 10 at four locations, front, rear, left, and right. Contact part 2
As shown in the cross-sectional view in Figure 2, it has a boat shape with the bottom periphery curved upward and the top open.
The lower end of the vertical support 3 is welded and fixed approximately at the center of the contact portion 2. The upper end of the vertical support 3 has a shape that allows it to come into contact with and support the transported object 10. Horizontal support 4
is installed almost horizontally above the conveyor 8, straddling the conveyor 8, and has two vertical supports 3 located at right angles to the conveyance direction of the conveyed object 10 near both ends thereof, two at the front and the rear. Connect, fix, and position.

5 is a trolley. The trolley 5 has an opening larger than the outer shape of the contact portion 2 on the top surface, and has a boat shape with both ends of the bottom surface located in the transport direction of the transported object 10 curved upward. A roller 6 is rotatably attached to the lower part of the trolley 5. The roller 6 is
As shown in FIG. 3, they may be attached to the four corners of the trolley 5, or as in another embodiment shown in FIG. 4, one wheel may be installed on the side B in the traveling direction and two wheels may be installed on the opposite side. Furthermore, the three wheels may be arranged in a manner opposite to that shown in FIG. The same number of trolleys 5 as the contact parts 2 of the stand 1 are installed.

Reference numeral 7 denotes rails, and two rails are installed in parallel to sandwich the conveyor 8 at an equal distance. The two rails are installed along the paint drying line so that the distance between the two rails matches the distance between the vertical supports 3 and 3 connected by the horizontal support 4. The width is about 100 mm wider than when using a trolley so that the rollers 6 can be installed side by side, and it has a U-shaped cross section with an upward opening and both side walls protruding upward. 8 is a conveyor, which in this embodiment is a chain conveyor. The conveyor 8 is installed approximately in the center between the two rails 7 along the paint drying line.

On the conveyor 8, hooks 9 capable of locking the center portion of the horizontal support 3 are installed at appropriate intervals so as to project upward.

Next, the operation of the embodiment will be explained. The object to be transported 10 is installed on the vertical support 3, and each contact part 2 of the stand 1 is positioned over the opening of the trolley 4 installed on one of the rails 6. is placed on trolley 4. When the horizontal support 4 is locked to the hook 9 of the conveyor 8, the stand 1 moves as the conveyor 8 moves.
At this time, the stand 1 is pressed against the trolley 5 due to the load of the car body 10, so as the conveyor 8 moves, the rollers 6 move along the inside of both side walls of the rail 7, and the trolley 5 is moved to the rail with the car body placed on it. 7
move on.

When the stand 1 is not in use, the stand 1 and the trolley 5 are separate bodies and are only in close contact with each other due to the pressing force caused by the load of the transported object 10, so that they can be separated. In addition, trolley 5 mutually
Furthermore, since the front and rear stands 1 are separate from each other, they are stored separately when not in use.

(Effect of the invention) Therefore, with this invention, the object to be transported can be transported according to the operation of the rollers. Moreover, since the structure is simple and the entire car body transfer device can be made smaller, heat loss can be reduced even when used in a paint drying line, making it possible to make the line smaller. Become. In other words, the line can be easily operated, cart storage is not required, and cleaning can be performed easily. In order to further reduce the weight, the rollers of the trolley can be made smaller.

Furthermore, when not in use, the trolley and stand can be stored separately, and since there is no need for a trolley, it is possible to reduce the storage space.
