Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a work positioning device in which a plate-shaped work guide member and a receiving member for receiving the back surface of the work guided by the guide member are arranged at positions corresponding to the peripheral shape of the work.

[0002]

[Prior art]

 This type of equipment is used when processing workpieces such as luggage door outers taken out from a pallet while applying sealer, or when assembling other workpieces such as luggage door inners from above. To be done. However, if the rigidity of the work is low, it will be twisted in the pallet or before it, and it will float from the receiving surface of the receiving member when it is set in the positioning device. There was an occasion.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the above circumstances, and an object thereof is to provide a work positioning device of the kind described at the beginning for setting a plate-shaped work in a state in which deformation such as twisting is forcibly corrected.

[0004]

[Means for Solving the Problems]

 The present invention provides a guide member that guides the periphery of a work set from above to a position corresponding to the peripheral shape of a plate-like work, and a receiving member that receives the back surface of the work that has been guided adjacent to this guide member. In order to achieve the above-mentioned object, in the work positioning device in which the suction cups mounted on the rod tip end are positioned at a standby position above the work receiving surface of the receiving member and lowered from this standby position. , The air cylinders for controlling the raising and lowering of the rod are arranged in at least four directions, and after the suction cup sucks the back surface of the work guided along the guide member to each air cylinder, the front edge of the suction cup is flush with the work receiving surface. Cylinder control means for stopping the rod when it detects that the rod has descended to the position is attached.

[0005]

[Action]

 With the suction cup standing by above the work receiving surface of the receiving member, the plate-like work is set from above to the front edge of the suction cup along the guide member, and the suction cup sucks the back surface portion of the associated work. Each cylinder control means lowers the rod after adsorbing the work, and detects that the rod has descended to a position where the front edge of the associated suction cup is flush with the work receiving surface and stops the rod. As a result, all four sides of the work are forcibly set in close contact with the work receiving surface of the original receiving member regardless of the presence or absence of deformation.

【Example】

 FIG. 1 shows a positioning device for a luggage door outer according to an embodiment of the present invention. Corresponding to the peripheral shape of the luggage door outer 1, a receiving member 10 with suction cups according to the present invention is provided at four corners and a receiving member 20 provided with a guide member 21 shown in FIG. ing.

As shown in FIG. 2, the receiving member with a suction cup 10 guides the guide member 2 which is inclined from the outside to guide the peripheral edge of the luggage door outer 1 set from above and the guide member 2 adjacent to this guide member. The pair of receiving members 3 and 3a which are separated from each other for receiving the back surface of the luggage door outer 1 and the suction cup 11 are attached to the tip end portion of the rod 13, and the position of the work receiving surface 3c of the receiving members 3 and 3a and An air cylinder 16 for controlling the lifting and lowering of the rod 13 so as to be positioned at a higher standby position is housed in the box 9 and configured as a unit. A cylinder control means 15 is attached to this air cylinder, which holds the rod 13 in the standby position and lowers it after suction so that the front edge 11a of the suction cup 11 is flush with the work receiving surface 3c. The rod position sensor 14 detects that 13 has descended and stops it.

The operation of the work positioning device configured as described above is as follows. When the suction door 11 is on standby above the work receiving surface 3c, the luggage door outer 1 stacked on the pallet is attracted by the robot hand and released along the guide members 2 and 21, It is set on the front edge 11a of the suction cup 11 along the guide surface. In this state, the suction cup 11 is sucked and sucked by the suction device through the suction tube 12 at the rear surface position of the belonging luggage door outer 1. Usually, the plate-like work tends to bend downward at the center, and therefore, regardless of whether or not it is deformed, it surely abuts the suction cups 11 on all four sides from above. The suction force is set so as not to damage or partially deform the work. In response to the suction end signal supplied from the suction device, the cylinder control means 15 lowers the rod 13, and when the rod position sensor 14 detects the lowering of the rod 13 to a predetermined position, the rod 13 is stopped, The front edge 11a of the suction cup 11 is positioned on the same plane as the work receiving surface 3c. As a result, the luggage door outer 1 is brought into close contact with the pair of work receiving surfaces 3c of the receiving member with suction cup 10 and the work receiving surface 20a of the receiving member 20.

With the deformation of the luggage door outer 1 from the reference surface thus corrected, the sealer is applied, and the luggage door inner is set from above to perform the assembling process. As a result, the sealer application or assembly work with the inner work, which is another work, can be performed with high accuracy.

In the above-described embodiment, the air cylinder provided with the suction cup has versatility by forming a unit with the receiving member, but it can be placed alone adjacent to the receiving member without being unitized. It is also possible to do it.

[0011]

[Effect of device]

 As described above, according to the present invention, the work is deformed because the suction cup waits at a position slightly higher than the original work receiving surface to adsorb the work, and then retracts to forcibly adhere to the work receiving surface. Even if it is done, it can be surely set on the work receiving surface, various processing accuracy in the set state is highly secured, and processing errors can be avoided. The work is not deformed due to suction by the suction cup.
