Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for setting doors, etc., which can be conveniently used in the process of attaching doors to automobile bodies transported on a fixed line.

Conventional devices of this kind are, for example,
As in the device described in Publication No. 36627, a device for setting a door, etc. is fixed at a fixed position on the floor surface, and therefore, in order to set a door, etc. on the car body with the setting device, the car body must be moved to the corresponding position. It is necessary to stop at a fixed position adjacent to the setting device. That is, there has been no known device that can automatically attach a door or the like to an automobile body that is being conveyed on a fixed path by a floor conveyor or the like without stopping the automobile body.

Of course, it is conceivable that the problem could be solved by moving a setting device such as a door synchronously with the vehicle body in the same direction and at the same speed beside the transportation path of the vehicle body.
Since the car body and mounting parts such as doors are placed on separate carts, even if both carts could be moved in perfect synchronization, the width direction of the car body on the car body transport cart would be If the positioning accuracy is not extremely high, not only will it not be possible to maintain a constant gap between the mounting parts such as a door when moving them horizontally toward the car body over a certain distance, but there is also a risk of damage due to undue pressure between the two parts. also occurs. Of course, it is extremely difficult to accurately and safely attach doors, etc. to the automobile body due to the relative positional accuracy between the automobile body transport vehicle and the door, etc. setting device, and the synchronized speed error between the two. .

The present invention proposes a device for setting doors, etc. that can solve the above-mentioned problems, and its features are as follows: (2) A body positioning and supporting means is provided on the carriage that can be moved in the same direction as the carriage at the same speed; (3) Further, a vertically movable table is provided on the cart, and is movable in a direction parallel to the moving direction of the cart. (5) The vertical movement table is further provided with a positioning stopper that can come into contact with a surface, and the vertical movement table is capable of horizontally moving between a receiving position for a mounting member such as a door and a setting position with respect to the main body, and that the mounting member is fixed in a predetermined position. (6) A vertical movement table driving means is provided for moving the vertical movement table rearward in order to bring the positioning stopper into contact with a specific surface of the main body. It is in.

In such an apparatus of the present invention, particularly in an apparatus of the present invention combined with the body positioning and supporting means described in item (2) above, a main body such as an automobile body is placed on the side of the trolley that is waiting at a predetermined position. When the supported carrier arrives, the carrier is started and made to travel in the same direction as the carrier at the same speed, and in this state, the main body positioning and supporting means lifts the main body on the carrier and moves the body in the width direction (travel of the carrier). By performing positioning in the left and right direction (orthogonal to the direction), the main body is transferred to a predetermined position in the width direction of the cart on the setting device side.

Next, the vertically movable base is moved rearward on the carriage by the vertically movable base driving means to a position where the positioning stopper abuts a specific surface on the main body side. As a result, when the mounting member supplying device is at the receiving position, the mounting member such as a door supported on the mounting member supplying device moves rearward together with the vertical movement table, and is moved to a predetermined position in the front and back direction with respect to the main body. positioned in position.

The main body supported on the trolley via the main body positioning support means and the mounting member supported on the trolley via the vertical movement base and the mounting member supply device are on a common trolley, so they are vertically disposed. Since there is a fixed positional relationship with respect to the direction, as a result of the positioning of the main body in the horizontal width direction on the trolley and the longitudinal positioning of the mounting member on the lighthouse truck, the mounting member is attached to the main body. They will be located opposite to each other at a fixed distance apart from the predetermined position. Therefore, by horizontally moving the attachment member supplying device in such a state to a setting position relative to the main body by a certain stroke, the attachment member on the supplying device can be set at a predetermined position on the main body. However, the work of joining the main body and the mounting member can be carried out by an automatic machine or the like under such conditions.

When the door set truck 4 is at the starting end standby position of its reciprocating path, the door D to be installed is transferred to the door supply device 10. That is, when the comb-shaped door transfer elevating loading platform 72 is in the raised position as shown by imaginary lines in FIGS. 2 and 3, the door D that has been previously transferred to the loading platform 72 is
is transferred onto the door lower end support means 19 of the door supply device 10 which is in the door receiving position a at the door receiving position X as shown in FIG. 4 by lowering the cargo receiving platform 72. The lower end D ₁ of the door D that is supported by the loading platform 72 and descends in this way
is accurately transferred to the door lower end support corner 53a of the support 55a of the door lower end support means 19 waiting at the door lower end receiving position P,
The outer surface D ₂ of the door D is brought into contact with the door outer surface suction support means 20 in a state where the suction cup 32 is retracted from the protective member 30 , and the door D is brought into contact with the door supply device 1 .
It is stably supported while leaning diagonally on zero. Next, as shown by imaginary lines in FIGS. 3, 7, and 9, the door pusher 45 of the door sliding means 22 is moved in the conveying direction 3 by the cylinder unit 43, and the door D is moved in the conveying direction 3.
The door D is pushed back and slid by the door pusher 45, and the door front end _D3 is brought into contact with the door front end positioning stopper 21, thereby positioning the door D in the transport direction 3. During the sliding process of the door D, the outer surface _D2 of the door slides on the protective material 30, and direct sliding contact between the suction cup 32 and the outer surface _D2 of the door can be avoided.

After the transfer and positioning of the door D to the door supply device 10 is completed as described above, the body B transported in the transport direction 3 by the transport trolley 1 is placed on the door set trolley 4 as shown in FIG. When the door set carriage 4 reaches the upper position of the body positioning support means 7, the door set carriage 4 is moved synchronously with the conveyance carriage 1 at the same speed and in the same direction. In this state, as shown in FIG. 2, the draining rib _B1 formed on the bottom side of the body B
Since the lifting table 60 of the means 7 is raised by the cylinder unit 61, the body B is lifted up to a predetermined height by the supporting table 62 via the draining rib _B1 , and the conveying cart 1 Float body B from the top. Next, as shown by the imaginary line in FIG. 15, the slide base 63 is advanced to the limit position by the cylinder unit 64, and the body B is moved in the width direction ₈ on the support base 62 via the draining rib B1 by the pressing part 65. 8 in the width direction of the body B using a total of four pressing parts 65, front, rear, left, and right.

After the body B has been transferred onto the four positioning support means 7 in the front, rear, left, and right directions and the positioning in the height direction and width direction 8 is completed, move the vertical movement table positioning stopper as shown by the imaginary line in FIG. The movable base 49 of No. 11 is advanced to a predetermined position by the cylinder unit 50, and its stopper plate 11a is moved forward.
facing the front facing surface _B3 of the frame part _B2 near the door hinge installation position of the body B,
As shown in FIG. 7, the vertical movement table 6 is moved in a direction opposite to the transport direction 3 by the cylinder unit 13. As a result, the stopper plate 11a of the stopper 11 is attached to the front surface of the frame portion of the body B.
Since it comes into contact with _B3 , the pressure in the cylinder unit 13 is kept constant to maintain this state. By positioning the vertical movement table 6 with respect to the body B in the transport direction 3 in this way, the horizontal movement table 9, the second horizontal movement table 16, and the door supply device 10 position the vertical movement table 6 on the vertical movement table 6. Door D
and the body B supported on each of the positioning support means 7 have a normal relative positional relationship in the transport direction 3 for door installation.

Next, as shown in FIG. 6, the horizontal movement table 9 is advanced by a stroke S by the cylinder unit 15, and at the same time, the tilting frame 23 is rotated clockwise in the figure around the horizontal axis 24 by the cylinder unit 25, and the door is opened. The supply device 10 is changed to the door setting position c in which the stopper 29 and the stopper roller 28 are in contact with each other. As the horizontal movement table 9 moves forward, the operating lever 33 of the door outer suction support means 20 separates from the end of the guide rod 14 and the suction cup 32 is pushed out by the spring 31. Therefore, by generating suction force in the suction cup 32 in advance, The door D approaches the body B with its outer surface D ₂ adsorbed by the suction cup 32, and is rotated together with the door supply device 10 around the horizontal axis 24 to change to the normal installation posture.

After the lateral movement table 9 reaches the forward limit position and the door feeding device 10 is changed to the door setting attitude c together with the door D, the second lateral movement table 16
By further advancing the cylinder unit 18 by the stroke s, the door feeding device 10, which is in the door setting position c, is further advanced together with the door D to reach the door setting position Y.
reach. At this time, the attachment 54 for positioning the support 55a that supports the lower end _D1 of the door
a is the stopper 6 of the body positioning support means 7;
6a to restrict movement of the door supply device 10 toward the body B side. That is, the forward movement of the second lateral movement table 16 by the cylinder unit 18 is continued until the attachment 54a comes into contact with the stopper 66a. As a result, as shown in FIGS. 6, 18, and 19, the door D is accurately fitted into the door mounting position of the body B, and the two upper and lower hinges attached to the front side of the door D are
The body mounting pieces H _{1 a} and H ₂ a of H 1 and H ₂ are attached to the frame B ₂ of the body B by the hands of an operator. Note that since this installation work is done from the inside of body B, the body mounting pieces H ₁ a and H ₂ a of the hinge
It is necessary to keep it in contact with the body frame part _B2 . Usually the body mounting piece H ₂ a of the lower hinge H ₂
is biased toward the body B side by a built-in spring, so the body mounting piece H ₂ a is naturally pressed against the body frame part B ₂ , but the body mounting piece H ₁ a of the upper hinge H ₁ is free. It is. Therefore, after the setting of door D is completed as described above,
As shown in FIG. 6, the presser lever 36 of the free hinge presser means 35 is rotated toward the body B side by the cylinder unit 38, and the body mounting piece _H1a of the hinge _H1 is attached to the body frame as shown in FIG. By pressing part _B2 with the tip of the presser lever 36,
This free body mounting piece _H1a can also be easily mounted from the inside of the body B.

Further, in the door setting state shown in FIGS. 6 and 18, the door D is moved between the support 55a and the suction cup due to the contact between the positioning attachment 54a of the door lower end support means 19 and the stopper 66a of the body positioning support means 7. 32, it is held at a predetermined position without being pressed against the body B at all, and the body B and the door D are not slightly deformed or scratched. Note that the door pusher 45 of the door sliding means 22 shown in FIGS. 3 and 9 has its side surface 45a facing the body B in contact with the outer surface of the body B during door setting. The door push shear 45 can move backward relative to the support base 42 against the spring 46.
The side surface 45a of the body B is not unduly pressed against the outer surface of the body B.

The work of attaching door D to body B is completed,
When the door set cart 4 reaches a predetermined position on the moving path, the suction support of the door outer surface _D2 by the suction cup 32 is released, and then the door supply device 10, the second lateral movement table 16, and the vertical movement are performed in the reverse order to the above. After returning the table 6 and the vertical movement table positioning stopper 11 to their original positions, further lowering the body positioning support means 7, and returning the body B onto the conveying cart 1 which is moving in synchronization with the door setting cart 4. The series of operations is completed by returning the door setting cart 4 to the standby position at the starting end of the movement path shown in FIG.

The device of the present invention can be implemented and used as described above, by temporarily transferring the main body such as the body from the conveyor truck onto the truck for setting the attachment member such as the door, and positioning it in the width direction. The positioning of the mounting member and the main body in the transport direction is as follows:
This is done by moving the attachment member supply device backward in the transport direction together with the vertical movement table and bringing the positioning stopper on the vertical movement table into contact with a specific surface of the main body, so that the main body is not supported on the transport vehicle. Even if the positional accuracy is low, the mounting member can be set with high precision relative to the main body. Moreover, the main body can be firmly fixed while being positioned in the width direction on the positioning support means (in the embodiment, the left and right draining ribs B ₁ are fixed by being clamped from both sides by the pressing parts 65), so that the mounting The setting and installation work of parts can be performed safely. Furthermore, even if some movement speed error occurs between the mounting member setting cart and the main body transporting cart, the setting and attachment work of the mounting member will not be hindered at all.

Furthermore, as shown in the embodiment, when the lateral movement stopper (stoppers 66a, 66b in the embodiment) for the mounting member supply device at the setting position is provided on the main body positioning support means, Since the positioning of the supply device can be performed at the part that is closest and integrated into the main body, the accuracy errors of each part are accumulated and the positioning accuracy is improved, as in the case where the mounting member supply device is moved laterally and a stopper is provided on the mechanism side. It is possible to perform highly accurate positioning not only in the lateral movement direction (width direction) but also in the height direction, etc., and the mounting member can be set with high accuracy.
