Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an opening / closing device for an automobile lid member which is mainly used in a painting line for opening and closing an upper opening type lid member such as a hood and a trunk lid provided on an automobile body.

[0002]

[Prior art]

 Conventionally, as this type of opening / closing device, a ceiling-mounted articulated robot is placed above the transport path that transports the car body along the painting line, and an engaging member for the lid member is attached to this robot. , A lid member that can be opened and closed, or a high-strength column is placed on a base installed on the side of the transport path, and a horizontal arm extending to the transport path side is supported by this column so that it can be raised and lowered. It is known that an engaging member for a lid member is attached to the tip of an elevating arm to open and close the lid member by raising and lowering the arm (see Japanese Patent Laid-Open No. 2-75369).

[0003]

[Problems to be solved by the device]

 The equipment cost increases when using the above-mentioned ceiling-mounted articulated robot, while the number of axes decreases when using an elevating arm, but a slide guide member for elevating the arm and a chain for elevating drive. A large reduction in equipment costs cannot be expected, because the number of parts will increase as a result of the need for ball screws and ball screws. In addition, in a device that uses a lifting arm, a strong column is installed at the side of the transport path, so the forced downward flow of floating paint disturbs the air flow that blows downward into the coating booth, and The coating pattern of the coating gun may be disturbed.In addition, when the paint scraps attached to the slide guide members for lifting and lowering provided on the column are peeled off by the lifting and lowering motion of the arm, the paint scraps ride on the disturbed air currents It may adhere and cause poor coating. In view of the above points, the present invention has an object to provide a small and inexpensive switchgear.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is an apparatus for opening and closing an upper opening type lid member provided on an automobile body on a conveying path, wherein a base provided on a side portion of the conveying path is provided substantially in the longitudinal direction of the conveying path. A drive source having substantially horizontal output shafts orthogonal to each other is mounted, and an arm extending toward the conveyance path is attached to the output shaft so that the front end of the drive shaft is separated from the axis of the output shaft by a predetermined distance. An engaging member for the lid member is provided.

[0005]

[Action]

 The arm is turned by the drive source with the engaging member engaged with the lid member of the automobile body on the transport path. At this time, the engaging member moves up and down while moving circularly on a vertical plane about the axis of the output shaft, and the lid member is opened and closed. Here, the base needs only to be high enough to mount the drive source, and the base can be configured to be small and compact, so that the downward air flow in the painting line is not disturbed by the base. Also, the structure is simple because it is sufficient to connect the arm directly to the output shaft.

[0006]

【Example】

 Referring to FIGS. 1 and 2, reference numeral 1 denotes a transport path for transporting an automobile body A along a coating line. The transport path 1 is moved to a side portion of the transport path 1 along a guide frame 2 in the longitudinal direction of the transport path 1. A self-supporting base 3 is provided, and a drive source 4 consisting of a motor 4a and a harmonic drive type speed reducer 4b is provided on the base 3 so that its output shaft, that is, the output shaft 4c of the speed reducer 4b, is long in the conveyance path 1. It was mounted so as to be positioned on a horizontal axis a orthogonal to the direction, and an arm 5 extending to the side of the transport path 1 was attached to the output shaft 4c.

The arm 5 extends obliquely with respect to the axis a so as to be separated from the axis a by a predetermined distance and extends straight to the transport path 1 side. An engaging member 6 that engages with an operator C attached to the front end of a hood B that is an upper opening type lid member provided in the body A is provided.

The arm 5 has a joint 5a in the middle, and the arm 5 can be bent by a cylinder 5b. Further, as shown in FIG. 3, the engaging member 6 is provided with a limit switch 7 having a detection piece 7a pushed by the operator C.

When the vehicle body A is stopped at a fixed position and the bonnet B is opened, the base 3 is made to stand by in front of the stopped position of the vehicle body A, and the arm 5 is turned obliquely rearward after the vehicle body is stopped. In this state, the base 3 is retracted, and when the detection piece 7a of the limit switch 7 comes into contact with the operator C and the switch 7 is turned on, the base 3 is temporarily stopped (state of FIG. 2A), and then driven. The source 4 is operated to rotate the arm 5 upward, and the base 3 is retracted. By this combined operation, the engaging member 6 is moved along an arc trace b centered on the hinge at the rear end of the bonnet B. , Open the hood B (state of FIG. 2 (b)). In this state, a coating robot (not shown) is used to coat the back of bonnet B and the interior of the engine room. After coating, move base 3 and arm 5 in the opposite direction to close bonnet B, then close arm 5 The vehicle body A is transported forward by bending it at the joint 5a so as not to interfere with the vehicle body A.

Although the base 3 is movable in the above embodiment, when the bonnet B is opened while the vehicle A is being transported, the arm 5 is rotated in synchronization with the transportation of the vehicle A to engage the engaging portion. The material 6 can be moved along the locus b, and the base 3 does not have to be movable. Further, although the arm 5 is attached to the output shaft 4c so as to cross the axis a in the above embodiment, the arm may be bent in an L shape so that the tip end thereof is separated from the axis a.

[0011]

[Effect of device]

 As is clear from the above description, according to the present invention, the lid member is opened and closed by the rotation of the arm, and it is not necessary to provide a tall column having a slide guide member for the arm on the base, The device is small and inexpensive, and if the lid member is opened and closed in the coating line with this device, it is possible to prevent the coating pattern from being disturbed by the turbulence of the air flow, and because there is no slide guide member that rubs against the arm, it adheres to the guide member. It is also possible to prevent problems such as the paint scraps peeling off and adhering to the vehicle body, and good painting can be performed.
